Description of the Invention The utility model relates to the field of water meters, in particular to a water meter collector.
BACKGROUND OF THE INVENTION Currently, most of the remote water meters on the market transmit information of multiple water meters of the same group of floors to a water meter collector, and then are transmitted to a computer management system via a water meter collector to complete remote meter reading, but the water meter collector is In the process of use, especially in the summer, when the water vapor touches the water meter collector, the water droplets may condense. It is known that the electronic equipment is easily damaged by the water, thus inventing a device that can prevent water droplets from forming on the water meter collector housing. An urgent problem to be solved.
Summary of the Invention In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a water meter collector, which can effectively prevent the water droplets from being generated on the shell of the water meter collector.
The utility model comprises a water meter collector body, a fixed shell and a driving shell. The fixed shell comprises a back plate, a support plate which protrudes vertically in the same direction from a lower end of the back plate, and an inner end of the support plate is provided with one end slidingly fixed on the back plate. The pressure plate is connected between the pressure plate and the support plate via a plurality of elastic members, the collector body is placed between two pressure plates, and a plurality of heat dissipation holes are arranged on the back plate and the support plate. A side of the device body facing away from the back plate is provided with an exhaust impeller facing the collector body. A worm wheel is coaxially connected to the back of the exhaust impeller, the worm gear meshes with a vertical worm, and one end of the drive shell is connected with a water meter. The joint is connected with a pipe joint at the other end of the driving shell, and the worm shaft is coaxially connected with a driving shaft. The driving shaft is rotatably connected to the driving shell and the free end of the driving shaft extends into the driving shell. The freedom of the driving shaft Connected to the end is a water wheel placed in the drive housing. 
Figure is a schematic front view of the utility model
The upper and lower pressure plates of the utility model can move up and down to facilitate the fixation of the collector body 1. After the collector body 1 is placed on the upper and lower pressure plates 4, the collector body 1 is positioned by the elastic force of the spring 502 at the two pressure plates 4. Between the expansion rods 501 are added so that the springs 502 have no vertical displacement but only vertical displacement. The inner side of the pressure plate 4 can be made as a friction surface, which increases the friction with the collector body 1 and makes the positioning of the collector body 1 more stable. The use of the pressure plate 4 can be applied to various sizes of the collector body 1 .
The utility model adopts the water flow as the power, does not increase the power, and achieves the effect of preventing the formation of water droplets by inducing the draft from the collector body, and the collector body is positioned under the action of the two pressure plates, and the disassembly is convenient and quick.

[Meter's Latest Patent] Water Meter Collector
[Chinese instrument network meter patent] creative limit, instrumentation invention. Today, we introduce a national patent for invention - water meter collector. The patent was applied for by Zhengzhou Litong Water Co., Ltd., and it was authorized on March 15, 2017. When the utility model is used, the collector body 1 is connected to a water meter, and then the water gauge connector 10 at one end of the drive shell 3 of the utility model is connected to the end of the water meter, and the pipe joint 11 of the drive shell 3 is connected to the water pipeline. When the water flows, the water pushes the water wheel 13 to rotate, and the water wheel 13 drives the drive shaft 12 to rotate the worm shaft 9 via the transmission rod 17, the worm wheel 9 drives the suction impeller 7 to rotate through the worm wheel 8, and the suction impeller 7 faces the collector body 1. In the ventilation process, since the pressure plate 4 and the back plate 201 have a plurality of ventilation holes 6, and the front and rear of the fixation case 2 do not have side plates, the wind passes around the collector body 1 and continuously blows the collector body 1 so as to collect the air. The surface of the device body 1 does not retain moisture, and the effect of preventing water droplets from being generated on the water meter collector body 1 can be replaced. The pumping impeller 7 can be replaced with a blower impeller, and the blower impeller blows air toward the collector body 1 , and the same can be achieved. effect. The utility model can not only achieve the effect of preventing the generation of water droplets, but also can achieve the effect of heat dissipation.
