[0002] An intelligent water meter is a new type of water meter that uses modern microelectronics technology, modern sensing technology, and intelligent IC card technology to measure water consumption and conduct water consumption data transmission and settlement transactions. Compared with traditional water meters that generally only have the functions of flow collection and mechanical pointer display of water consumption, it is a great progress.

[0043] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0044] Embodiment 1

[0045] Refer to Figures 1-5 , a waterproof performance detection device for the plastic shell of an intelligent water meter, including a main body assembly 1. The main body assembly 1 includes: a frame body 11, with a water outlet pipe 12 connected through its front side; a processing assembly 2 is arranged on the frame body 11. The processing assembly 2 includes: a bottom plate 211 symmetrically arranged on the outer side wall of the frame body 11; electric push rods 21 symmetrically and fixedly connected to the top of the bottom plate 211; a support frame 22 fixedly connected to the top of the electric push rods 21; support brackets 231 symmetrically arranged at the bottom of the support frame 22; a bidirectional lead screw 23 rotatably connected between the support brackets 231, and the right end of the bidirectional lead screw 23 penetrates through the support bracket 231; a motor 232, whose output shaft is fixedly connected to the right end of the bidirectional lead screw 23; threaded blocks 24 symmetrically and threadedly connected to the bidirectional lead screw 23; vertical plates 25 symmetrically and fixedly connected to the bottom of the threaded blocks 24; cross plates 251 symmetrically arranged on the facing surfaces of the vertical plates 25; an intelligent water meter body 26 arranged on the top of the cross plates 251; a detection mechanism 27 arranged on the frame body 11 and the intelligent water meter body 26. The detection mechanism 27 includes: a support plate 271 fixedly connected to the rear side wall of the frame body 11; an air inflation pump 272 fixedly connected to the top of the support plate 271; a hose 273 connected through the top of the air inflation pump 272; an air outlet head 274 connected through the port of the hose 273; a connector 275 connected through the top of the intelligent water meter body 26 and threadedly connected to the air outlet head 274. Through holes are symmetrically formed in the vertical plates 25 and the cross plates 251.

[0046] In use, the staff first place the intelligent water meter body 26 on the top of the horizontal plate 251, start the motor 232, the motor 232 drives the bidirectional lead screw 23 to rotate, and the threaded blocks 24 threadedly connected to the bidirectional lead screw 23 drive the vertical plate 25 and the horizontal plate 251 to approach each other until the vertical plate 25 fits against both sides of the intelligent water meter body 26, completing the fixation of the intelligent water meter body 26. At this time, rotate the air outlet head 274 and connect the air outlet head 274 to the connection head 275. After adding an appropriate amount of pure water to the frame 11, control the electric push rod 21 to lower the support frame 22, and the intelligent water meter body 26 fixed at the bottom of the support frame 22 together with the horizontal plate 251 falls into the water. When the intelligent water meter body 26 is completely submerged, the detection mechanism 27 detects the waterproofness of the intelligent water meter body 26: the staff starts the air pump 272, and the air pump 272 fills the inside of the shell of the intelligent water meter body 26 with gas through the hose 273. The staff observes the change of the pure water inside the frame 11. When the waterproofness of the shell of the intelligent water meter body 26 is poor, bubbles will be generated at the break of the shell of the intelligent water meter body 26. When the waterproofness of the shell of the intelligent water meter body 26 is good, no bubbles will be generated. The through holes on the vertical plate 25 and the horizontal plate 251 facilitate the pure water to fully contact the shell of the intelligent water meter body 26, avoiding incomplete detection results.

[0047] Embodiment 2

[0048] Based on Embodiment 1, an auxiliary function is added.

[0049] Refer to Figures 1-5 As shown in [reference figure], symmetrically fixedly connected between the brackets 231 are optical axes 241, the optical axes 241 penetrate through the threaded blocks 24, and the threaded blocks 24 are slidably connected to the optical axes 241. Symmetrically arranged on the inner side wall of the frame 11 are underwater cameras 4. Symmetrically arranged at the bottom of the bidirectional lead screw 23 are springs 31, the bottoms of the springs 31 are fixedly connected to a pressing plate 3, and through holes are also evenly formed in the pressing plate 3.

[0050] When the threaded block 24 moves on the bidirectional lead screw 23, it slides on the optical axes 241 on both sides. The optical axes 241 guide the movement of the threaded block 24, increasing the stability of the threaded block 24 during movement. The underwater cameras 4 are dispersedly arranged with adjustable angles, facilitating the omnidirectional observation of the bubbles around the shell of the intelligent water meter body 26, facilitating the capture of the bubble generation situation in areas that are inconvenient for the staff to observe, and increasing the comprehensiveness of the detection results. When the intelligent water meter body 26 is placed in front of the horizontal plate 251, the staff lifts the pressing plate 3 upward. The pressing plate 3 compresses the spring 31, places the intelligent water meter body 26 on the horizontal plate 251, and when the vertical plate 25 fits against the outer side wall of the intelligent water meter body 26, releases the pressing plate 3. The spring 31 moves the pressing plate 3 downward until the pressing plate 3 contacts the upper surface of the intelligent water meter body 26, increasing the stability of the intelligent water meter body 26 after fixation. Since the positions of the vertical plate 25, the horizontal plate 251, and the pressing plate 3 are all adjustable, the device is convenient for detecting the waterproof performance of intelligent water meter bodies 26 of different specifications, and has strong practicability.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
