[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A water meter maintenance and testing device, comprising a housing 1;

[0032] The housing 1 is equipped with a backwashing cleaning mechanism 2 for backwashing and cleaning the water meter filter screen and guide vanes;

[0033] The housing 1 is equipped with a reading detection mechanism 3 for detecting the accuracy of the water meter movement;

[0034] The reading detection mechanism 3 includes a detection placement component 31, a sealing downward movement component 32, and a sealing component 33; the housing 1 and the sealing component 33 are both connected to the detection placement component 31; the housing 1 and the sealing component 33 are both connected to the sealing downward movement component 32; the detection placement component 31 is used to monitor the accuracy of the movement; the sealing downward movement component 32 is used to drive the sealing component 33 downward; the sealing component 33 is used to seal the movement detected by the detection placement component 31.

[0035] In this invention, when the operator performs maintenance on the water meter, the water meter mechanism is first removed, and then the filter screen and guide vanes are removed from the lower end of the mechanism. After the filter screen and guide vanes are fixed in place by the reading detection mechanism 3, they are backwashed and cleaned. While backwashing and cleaning, the operator puts the mechanism into the detection placement component 31, and then the sealing moving component 32 drives the sealing component 33 to move down. The sealing component 33 and the detection placement component 31 cooperate to seal the mechanism, and then the detection placement component 31 monitors the accuracy of the mechanism. This allows for automatic detection of the mechanism without disassembling the meter case and water pipes when the water meter needs to be inspected during maintenance; the filter screen and guide vanes are backwashed and cleaned at the same time.

[0036] The detection placement assembly 31 includes a detection housing 311, a water storage tank 312, and a water inlet tank 313. The water storage tank 312 is fixedly installed on the inner side wall of the left rear end of the housing 1, and the water inlet tank 313 is fixedly installed on the inner side wall of the left front end of the housing 1. The water inlet and outlet of the detection housing 311 are fixedly connected to the water storage tank 312 and the water inlet tank 313, respectively, and the water inlet and outlet of the detection housing 311 are connected to the water storage tank 312 and the water inlet tank 313, respectively. A water filter screen and guide vanes are installed in the detection housing 311. The detection housing 311 is connected to the sealing assembly 33. A submersible pump is fixedly installed in the water storage tank 312, with the water inlet of the submersible pump connected to the water storage tank 312 and the water outlet of the submersible pump connected to the detection housing 311.

[0037] The sealing downward moving assembly 32 includes a second cylinder 321, a limiting rod 322, and a vertical moving plate 323; the second cylinder 321 is fixedly installed on the outer side wall of the left front end of the housing 1; the driving end of the second cylinder 321 is fixedly connected to the front end of the vertical moving plate 323, the rear end of the vertical moving plate 323 is slidably connected to the limiting rod 322, and the lower end of the limiting rod 322 is fixedly connected to the upper end of the water storage tank 312; the vertical moving plate 323 is connected to the sealing assembly 33.

[0038] The sealing assembly 33 includes a cylinder 331, a rack 332, a gear 333, and a test cover 334. The lower end of the cylinder 331 is fixedly connected to the vertical moving plate 323. The driving end of the cylinder 331 is fixedly connected to the rack 332. The lower end of the rack 332 is slidably connected to the limiting groove opened at the upper end of the vertical moving plate 323. The rack 332 is meshed with the gear 333, the gear 333 is rotatably connected to the upper end of the vertical moving plate 323, and the gear 333 is connected to the test cover 334 by a key, so that while the gear 333 drives the test cover 334 to rotate, the test cover 334 can move up and down. The test cover 334 is threadedly connected to the vertical moving plate 323, and the lower end of the test cover 334 is threadedly connected to the test case 311.

[0039] In this invention, the operator installs the meter core and impeller to be tested onto the filter screen and guide vanes in the meter housing 311. Then, cylinder 2 321 drives the vertical moving plate 323 to slide downward along the limiting rod 322, so that the lower end of the meter cover 334 abuts against the upper end of the meter housing 311. Then, cylinder 331 drives the rack 332 to slide backward, the rack 332 drives the gear 333 to rotate, and the rotation of the gear 333 drives the meter cover 334 to rotate. The rotation of the meter cover 334 causes the lower end of the meter cover 334 to be screwed into cylinder 331. 31 is sealed to cylinder 331; at this time, the inside of the water inlet 313 is empty, and the submersible pump installed in the water storage tank 312 starts to inject water into the water inlet 313 through the detection case 311. When water is injected, the water flow drives the dial of the watch movement to rotate through the impeller. Because the capacity of the water inlet 313 is constant, after the water inlet 313 is filled with water, the accuracy of the watch movement can be checked by observing whether the increase in the dial of the watch movement is the same as the capacity of the water inlet 313. This realizes that when the accuracy of the watch movement needs to be tested during water meter maintenance, the watch movement can be automatically tested simply by removing the watch movement.

[0045] In this invention, the operator places the removed filter screen and guide vanes into the placement hole 212 on the positioning plate 211. Then, cylinder 223 drives block 224 to slide backward on the positioning plate 211. Block 224 drives slide rod 221 to slide along the limiting groove 222. The two slide rods 221 respectively block the filter screen and guide vanes to prevent them from falling off. Then, high-pressure nozzle 231 is activated to backwash and clean the filter screen and guide vanes. After cleaning, cylinder 223 drives block 224 to reset. At the same time, reset spring 225 drives slide rod 221 to slide along the limiting groove 222 to reset, releasing the fixation of the filter screen and guide vanes. At this time, the filter screen and guide vanes are removed, thus achieving backwash cleaning of the filter screen and guide vanes.
