Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 8In an embodiment of the present invention, an ultrasonic water meter for preventing clogging includes a water meter barrel 1, a water inlet pipe 101 is fixedly installed at the side end of the water meter barrel 1, a water outlet pipe 102 is fixedly installed at one end of the water meter barrel 1 away from the water inlet pipe 101, an ultrasonic detection mechanism 2 for detecting water flow is arranged inside the water meter barrel 1, the ultrasonic detection mechanism 2 uses the time difference data measured by the ultrasonic transducer to calculate the water flow rate in real time through processing by a computing chip, and has the function of accumulating the instantaneous flow rate as a cumulative flow rate, a filtering mechanism 3 for filtering impurities in the water flow is arranged at one end of the water inlet pipe 101 away from the water meter barrel 1, the filtering structure filters the water entering the water inlet pipe 101 to prevent the water meter barrel 1 from being blocked, and a collecting mechanism 4 for replacing and cleaning the filtering mechanism 3 to collect the filtered debris is arranged at the lower end of the water meter barrel 1 near the filtering mechanism 3, the collecting mechanism 4 removes and collects the debris filtered by the filtering mechanism 3, so that the water meter can be used for a long time without being blocked.

[0036] See also Figure 1 , Figure 2 The ultrasonic detection mechanism 2 includes an ultrasonic device 201, and the ultrasonic device 201 is symmetrically installed on the inner wall of the water meter barrel 1. The ultrasonic device 201 is a prior art and will not be described in detail herein. Ultrasonic waves are emitted by the ultrasonic device 201, and the ultrasonic device 201 at the other end receives the ultrasonic signals. The water flow and flow rate are calculated by the received ultrasonic signals. A display water meter 202 is fixedly installed on the upper end of the water meter barrel 1, and a data line 203 is fixedly installed on the output end of the display water meter 202. A processor 204 is fixedly installed on one end of the data line 203 away from the display water meter 202, and the processor 204 is fixedly installed on the upper end of the water meter barrel 1. The processor 204 is a prior art and will not be described in detail herein. As described above, a connecting line 205 is fixedly installed between the processor 204 and the ultrasonic device 201. The working principle is based on the time difference method, that is, by installing a pair of ultrasonic devices 201 at the upstream and downstream of the pipeline respectively, ultrasonic signals are transmitted and received mutually. Since the ultrasonic signal is superimposed on the water flow signal, the propagation speed of the downstream and upstream is different, thereby forming a time difference.

The telescopic spring arranged between the fixed cylinder 305 and the sliding ring 306 makes the filter 307 suffer greater resistance when more debris is filtered by the filter 307, so that the sliding ring 306 moves a greater distance, and the force of squeezing the telescopic spring is greater. The inner wall of the fixed cylinder 305 is provided with a A sliding groove 308 is provided, and a sliding block 309 is slidably installed in the sliding groove 308. A return spring 310 is fixedly installed between the sliding block 309 and the fixed cylinder 305.

A control line 311 is fixedly installed on one end of the sliding block 309 close to the return spring 310. When the sliding ring 306 slides to one side of the sliding block 309, the sliding ring 306 pushes the sliding block 309 to move, driving the control line 311 to start moving.

[0040] See also Figures 1 to 5The transmission rod 312 is rotatably installed at one end of the installation cylinder 303 close to the water meter cylinder 1, and the transmission rod 312 is fixedly installed at the rotating end of the turbine generator 210 at one end away from the installation cylinder 303. A limiting groove 313 is provided on the inner wall of the installation cylinder 303 close to the control line 311, and a limiting block 314 is slidably installed in the limiting groove 313. A limiting spring 315 is fixedly installed between the limiting groove 313 and the limiting block 314, so that when the limiting block 314 no longer moves, the limiting spring 315 pushes the limiting spring 315 to move to the original position more conveniently, and the installation cylinder 303 is close to the control line 311. A tightening ring 302 is rotatably installed on the outer wall of the near limit block 314. The above-mentioned tightening ring 302 is a multilateral tightening throat clamp ring in the prior art, which will not be described in detail here. After the tightening ring 302 is tightened, the tightening ring 302 slowly returns to its original state when the tightening ring 302 is no longer tightened, and the end of the control line 311 away from the sliding block 309 is fixedly installed on the control end of the tightening ring 302. When the control line 311 pulls the tightening ring 302, the tightening ring 302 pushes the limit block 314 to squeeze the transmission rod 312, so that the mounting tube 303 drives the mounting plate 304 to start rotating.

[0041] See also Figures 1 to 8 The collecting mechanism 4 includes a cleaning brush 401, which is configured as a burr cylindrical brush, and the bristles of the cleaning brush 401 are configured as an elastic plastic material. The cleaning brush 401 cleans the filtered residue of the filter screen 307 during the rolling process, so that the filtered residue is separated from the filter screen 307. A cleaning box 402 is fixedly installed on the outer wall of the filter box 301 close to the cleaning brush, and a cleaning frame 403 is fixedly installed on the inner wall of the cleaning box 402.

The cleaning ropes 407 wound on the winding discs 405 can make the cleaning brush 401 rotate to wind the cleaning rope 407 at one end during the rotation process, and rotate to release the cleaning rope 407 at the other end, so that the cleaning brush 401 can move up and down.

[0042] See also Figures 1 to 8A cleaning ring 408 is rotatably mounted on the outer wall of the cleaning brush 401 close to the winding disk 405, and a rubber telescopic rope 409 is fixedly mounted on the upper end of the cleaning ring 408, and the other end of the rubber telescopic rope 409 is fixedly mounted on the inner wall of the cleaning box 402. The rubber telescopic rope 409 provided on the cleaning brush 401 is elastic, so that when the cleaning brush 401 moves, the cleaning brush 401 is pulled to prevent the cleaning rope 407 from detaching from the winding disk 405 during the winding process. A tooth rack 410 is fixedly mounted on the side end of the cleaning ring 408, and a collecting box 411 is fixedly mounted on the side end of the cleaning box 402 close to the tooth rack 410, and the tooth rack 410 is slidably mounted on the inner wall of the collecting box 411. When the bristles on the cleaning brush 401 rotate to one side of the tooth rack 410, the tooth rack 410 collects the impurities filtered by the filter net 307 cleaned by the bristles on the cleaning brush 401.

[0043] See also Figures 1 to 8 A driven gear ring 412 is fixedly installed at one end of the cleaning brush 401 away from the winding disk 405, and a control rod 413 is rotatably installed on the inner wall of the cleaning box 402 close to the driven gear ring 412. A transmission gear ring 414 is slidably sleeved on the outer wall of the control rod 413. A protrusion is provided on the outer wall of the control rod 413, and a groove is provided on the inner wall of the transmission gear ring 414 that matches the protrusion of the control rod 413, so that when the control rod 413 rotates, the transmission gear 417 can slide on the outer wall of the control rod 413, and the transmission gear ring 414 is meshed and connected with the driven gear ring 412, and a connecting gear 415 is fixedly installed on the upper end of the control rod 413, and the side of the connecting gear 415 A rotating gear rod 416 is fixedly installed at the end, and a transmission gear 417 is fixedly installed on the outer wall of the rotating gear rod 416 close to the transmission rod 312, and an active gear ring 418 meshing with the transmission gear 417 is fixedly installed on the outer wall of the transmission rod 312 close to the transmission gear 417. When the water flow drives the transmission rod 312 to start rotating, the active gear drives the transmission gear 417 to start rotating, the control rod 413 drives the rotating gear rod 416 to rotate, the rotating gear rod 416 drives the connecting gear 415 to start rotating, and the transmission gear 417 drives the driven gear ring 412 to start rotating, so that the cleaning brush 401 starts to rotate, so that the cleaning brush 401 can keep rotating during the up and down movement.

[0044] The working principle of the present invention is: when the ultrasonic water meter is detecting water flow, water flows through the turbine generator 210, so that the water flows to charge the storage battery 207, so that the ultrasonic water meter does not need to replace the battery and has a long-term access to the power supply when detecting flow data, thereby achieving energy saving;

[0045] At the same time, the water flows through the filter 307, which removes impurities in the water flow, thereby preventing scale from being generated in the water meter barrel 1, causing the flow sensing area of ​​the ultrasonic water meter to be blocked and the sound wave data of the ultrasonic device 201 to be infected, thereby playing a protective filtering role;

[0046] After the ultrasonic water meter is used for a long time, the filter 307 is clogged, and the resistance of the filter 307 increases, so that the filter 307 drives the sliding ring 306 to start moving, and the sliding ring 306 drives the sliding block 309 to start moving. The sliding block 309 causes the control line 311 to pull the tightening ring 302 to start shrinking, so that the tightening ring 302 drives the sliding block 309 to start moving, and the limit block 314 abuts against the outer wall of the transmission rod 312. The transmission rod 312 drives the mounting plate 304 to start rotating through the limit block 314, so that the ultrasonic water meter can automatically replace the new filter 307;

[0047] When the transmission rod 312 starts to rotate, the driving gear drives the transmission gear 417 to start rotating, the control rod 413 drives the rotating gear rod 416 to rotate, the rotating gear rod 416 drives the connecting gear 415 to start rotating, and the transmission gear 417 drives the driven gear ring 412 to start rotating, so that the cleaning brush 401 starts to rotate. When the cleaning brush 401 starts to rotate, the cleaning rope 407 wound on the winding disk 405 causes the cleaning brush 401 to rotate at one end to wind the cleaning rope 407 and rotate at the other end to release the cleaning rope 407 during the rotation process, so that the cleaning brush 401 can move up and down to clean the filter 307, and the cleaning brush 401 removes and collects the residue and debris on the filter 307, thereby making the cleaning of the filter 307 more convenient.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
