[0011] In an embodiment of the present invention, a receiving plate is arranged below the scraping plate on the side where the sludge flows out of the material receiving box.

[0012] In an embodiment of the present invention, two groups of insertion holes are arranged on the inner wall of the annular water tank. A blocking plate is inserted into the insertion holes.

[0016] 1. An automatic silt cleaning device for a water tank according to the present invention is provided with a drag plate below a sealing plate. During use, the bottom end of the drag plate contacts the inner bottom wall of the annular water tank. Then, as the sealing plate rotates with the rotating frame, when the bottom surface of the drag plate rotates relative to the inner bottom wall of the annular water tank, the silt deposited on the inner bottom wall of the annular water tank is scraped off its original position, causing the silt to flow out of the inner bottom wall of the annular water tank.

The vibrator vibrates on the surface of the discharge pipe, causing the discharge pipe to vibrate synchronously, and the discharge port of the annular water tank connected to the discharge pipe vibrates synchronously. Under the action of the vibration force, the silt accumulated above the discharge port accelerates through the discharge pipe, and the content of silt adhering to and remaining on the inner wall of the annular water tank can be reduced, which is beneficial to improving the cleaning effect of the silt.

Detailed implementation manner

[0030] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited are not intended to limit the present invention.

[0031] Referring to Figures 1 - 8 As shown, an automatic silt cleaning device for a water tank of the present invention includes an annular water tank 1. A first bracket 11 is provided on the bottom surface of the annular water tank 1. A second bracket 12 is provided at the center of the annular water tank 1. A driving motor is provided on the surface of the second bracket 12. A plurality of connecting frames 13 are evenly arranged in a ring at the top end of the output end of the driving motor. The bottom end of the connecting frame 13 is fixedly connected to a rotary frame 14. A sealing plate 15 is provided below the rotary frame 14. The sealing plate 15 is inserted into the notch of the annular water tank 1 and a connecting block is provided between the sealing plate 15 and the rotary frame 14. A pair of first telescopic rods 2 are provided on the top surface of the sealing plate 15. The bottom end of the output end of the first telescopic rod 2 penetrates through the sealing plate 15 and is fixedly connected to a drag plate 21. Both ends of the drag plate 21 are in contact with the inner and outer annular inner walls of the annular water tank 1. A pair of discharge ports 3 are opened on the inner bottom wall of the annular water tank 1. A discharge pipe 31 is inserted into the discharge port 3. A first electric valve is provided inside the discharge pipe 31. A receiving box 32 is installed below the discharge pipe 31. The opening of the receiving box 32 is in an open state;

[0032] When the embodiment of the present invention is in use, liquid water is injected into the annular water tank 1. At the same time, the first telescopic rod 2 is started. The first telescopic rod 2 drives the drag plate 21 to move downward through the output end and stops when the bottom surface of the drag plate 21 contacts the inner bottom wall of the annular water tank 1. Then the driving motor is started. The driving motor drives the rotary frame 14 to rotate through the connecting frame 13 on the output end. The rotary frame 14 drives the sealing plate 15 below to rotate on the notch of the annular water tank 1 through the connecting block. The sealing plate 15 drives the drag plate 21 to rotate in the annular water tank 1 through the first telescopic rod 2. When the bottom surface of the drag plate 21 rotates relative to the inner bottom wall of the annular water tank 1, the silt deposited on the inner bottom wall of the annular water tank 1 is scraped off from its original position, so that the silt flows out of the inner bottom wall of the annular water tank 1. By controlling the output of the driving motor, the drag plate 21 is made to push the silt to gather at the discharge port 3. Then the first electric valve inside the discharge pipe 31 inserted into the discharge port 3 is controlled to open. The silt gathered above the discharge port 3 flows downward with the liquid water through the discharge pipe 31 and is finally collected by the receiving box 32 below the discharge pipe 31. After the drag plate 21 completely scrapes the silt deposited in the annular water tank 1 and discharges it through the discharge port 3, the first electric valve is controlled to close. The above process of cleaning the silt deposited in the annular water tank 1 is completed by the drag plate 21 located inside the annular water tank 1, replacing manual cleaning inside the annular water tank 1, which has the advantages of high cleaning efficiency, low cost and prevention of safety hazards.

[0033] A vibrator 33 is arranged on the surface of the discharge pipe 31. After the first electric valve in the discharge pipe 31 is opened, the silt gathered above the discharge port 3 will flow downward with the liquid water. At this time, the vibrator 33 is started. The vibrator 33 vibrates on the surface of the discharge pipe 31, making the discharge pipe 31 vibrate synchronously, and the discharge port 3 of the annular water tank 1 connected to the discharge pipe 31 vibrates synchronously. Under the action of the vibration force, the silt gathered above the discharge port 3 accelerates through the discharge pipe 31, and the content of the silt adhering and remaining on the inner wall of the annular water tank 1 can be reduced, which is beneficial to improving the cleaning effect of the silt.

[0034] A pair of air jets 22 are symmetrically arranged on both sides of the drag plate 21. Two sets of air pumps 23 are arranged on the top surface of the sealing plate 15. Each set of air pumps 23 has two. A conduit 24 is arranged between the air pumps 23 and the air jets 22. When the drag plate 21 scrapes the silt deposited on the inner bottom wall of the annular water tank 1, the air pumps 23 are started. The air pumps 23 jet air to the air jets 22 through the conduit 24. The air jets 22 jet airflows pointing to the surface of the drag plate 21. When the airflows enter the liquid water, the liquid water is driven. The driven liquid water acts on the surface of the drag plate 21 to prevent the silt from adhering and accumulating on the surface of the drag plate 21.

[0035] A liquid extraction pump 7 is provided at the top of the material receiving box 32. The input end of the liquid extraction pump 7 is inserted into the interior of the material receiving box 32. The output end of the liquid extraction pump 7 is connected with a return pipe 71. The top end of the return pipe 71 penetrates into the annular water tank 1, and a one-way valve with the valve port pointing to the annular water tank 1 is arranged inside the return pipe 71. After the sludge enters the interior of the material receiving box 32 along with the liquid water, when the sludge settles to the bottom of the material receiving box 32, the liquid extraction pump 7 is started. The input end of the liquid extraction pump 7 pumps the liquid water above the sludge, and then injects it into the annular water tank 1 through the return pipe 71, completing the reuse of the liquid water.

[0036] A pair of partition plates 4 are symmetrically inserted through the two side surfaces of the material receiving box 32. The end of the partition plate 4 is provided with a first linkage frame 42. The end of the first linkage frame 42 away from the partition plate 4 is provided with a second telescopic rod 41, and the second telescopic rod 41 is installed on the side surface of the material receiving box 32. After the sludge settles into the material receiving box 32, the second telescopic rod 41 is started. The second telescopic rod 41 drives the partition plate 4 to move into the interior of the material receiving box 32 through the first linkage frame 42, and stops after the pair of partition plates 4 are butted. After the partition plates 4 are butted, the sludge is sealed below, and the liquid water is above the partition plates 4. When the liquid water in the material receiving box 32 is extracted by the liquid extraction pump 7, the partition plates 4 will prevent the sludge from being pumped back into the annular water tank 1, preventing the sludge from flowing back.

[0037] A pair of scraping plates 52 are symmetrically inserted through the two ends of the material receiving box 32. A second linkage frame 51 is arranged on the surface of one scraping plate 52, and a third telescopic rod 5 is arranged between the second linkage frame 51 and the surface of the material receiving box 32. A third linkage frame 54 is arranged on the surface of the other scraping plate 52, and a fourth telescopic rod 53 is arranged between the third linkage frame 54 and the material receiving box 32. Docking holes are opened at both ends of the material receiving box 32, and the scraping plates 52 are inserted into the docking holes. When there is too much sludge precipitation in the material receiving box 32 and it needs to be cleaned, during the cleaning, the third telescopic rod 5 is started. The third telescopic rod 5 drives the scraping plate 52 to move into the interior of the material receiving box 32 through the second linkage frame 51. At the same time, the fourth telescopic rod 53 is started. The fourth telescopic rod 53 drives the other scraping plate 52 to move out of the material receiving box 32 through the third linkage frame 54, so that the scraping plates 52 open the docking holes penetrating through the side surface of the material receiving box 32, and the other scraping plate 52 pushes the sludge deposited at the bottom of the material receiving box 32 to move, and then flows out of the material receiving box 32 through the docking holes, completing the cleaning of the sludge in the material receiving box 32. Compared with manual cleaning, it is more convenient and reduces the labor intensity.

[0038] A receiving plate 6 is arranged below the scraping plate 52 on the side where the sludge flows out of the material receiving box 32. The sludge flowing out of the material receiving box 32 is received by the receiving plate 6, and the staff only needs to collect the sludge on the receiving plate 6, which is convenient for the staff to collect the sludge flowing out of the material receiving box 32.

[0039] On the inner wall of the annular water tank 1, there are two groups of insertion holes 8. Inside the insertion holes 8, there is a blocking plate 81 inserted. On the bottom surface of the blocking plate 81, there is a fourth linkage 83. Between the fourth linkage 83 and the bottom surface of the annular water tank 1, there is a fifth telescopic rod 82. After the silt on one side of the discharge port 3 in the annular water tank 1 is pushed by the drag plate 21 and gathers above the discharge port 3, it is necessary to move the drag plate 21 in the reverse direction so that the silt on the other side of the discharge port 3 is also gathered above the discharge port 3. When the drag plate 21 moves away from the discharge port 3, first start the fifth telescopic rod 82. The fifth telescopic rod 82 drives the blocking plate 81 to move into the annular water tank 1 through the fourth linkage 83. The blocking plate 81 moves attached to the surface of the drag plate 21, isolating the drag plate 21 from the silt gathered above the discharge port 3. After that, when the drag plate 21 moves, the silt gathered on one side of the discharge port 3 is blocked, so that when the drag plate 21 moves in the annular water tank 1, the silt gathered at the discharge port 3 is difficult to be driven by the surging liquid water to spread. Similarly, on the other side of the discharge port 3, the blocking plate 81 will also block the other side of the discharge port 3. After that, when the silt is discharged through the discharge port 3, a pair of blocking plates 81 isolate the discharge port 3, preventing a large amount of liquid water from being discharged through the discharge port 3, resulting in more liquid water being replenished in the annular water tank 1 later, which affects the use of the cooler.

[0040] Refer to Figure 1 , Figure 9 , Figure 10 As shown in the figure, on the side of the annular water tank 1, there is a pair of water tanks 84. The side of the water tank 84 is penetrated and inserted with a water outlet pipe 85. The end of the water outlet pipe 85 penetrates into the annular water tank 1, and a second electric valve is arranged inside. At the same time, a water pump is arranged at the water inlet end of the water outlet pipe 85. After the blocking plate 81 restricts the silt above the discharge port 3, there may be residues when the silt is discharged along with the liquid water between the pair of blocking plates 81. Therefore, the water tank 84 is provided. When the liquid water between the pair of blocking plates 81 drains out, open the second electric valve inside the water outlet pipe 85. The water tank 84 sprays liquid water into the annular water tank 1 through the water pump inside the water outlet pipe 85. The liquid water drives the remaining silt above the discharge port 3 to flow downward again, further improving the cleaning effect of the silt.

[0041] At the water outlet end of the water outlet pipe 85, there are a plurality of inclined plates 86. When the liquid water sprayed out by the water outlet pipe 85 passes through the inclined plates 86, the liquid water is adjusted downward to impact the inner bottom wall of the annular water tank 1. The liquid water sprayed out by the water outlet pipe 85 is sprayed out after being received by the inclined plates 86. The receiving direction of the sprayed liquid water by the inclined plates 86 is downward, flushing the remaining silt on the inner bottom wall of the annular water tank 1, accelerating the flow of the remaining silt along with the liquid water, and further optimizing the cleaning efficiency of the remaining silt.

[0042] During use, inject liquid water into the annular water tank 1. At the same time, start the first telescopic rod 2. The first telescopic rod 2 drives the drag plate 21 to move downward through the output end. Stop when the bottom surface of the drag plate 21 contacts the inner bottom wall of the annular water tank 1. Then start the drive motor. The drive motor drives the rotary frame 14 to rotate through the connecting frame 13 on the output end. The rotary frame 14 drives the sealing plate 15 below to rotate on the notch of the annular water tank 1 through the connecting block. The sealing plate 15 drives the drag plate 21 to rotate in the annular water tank 1 through the first telescopic rod 2. When the bottom surface of the drag plate 21 rotates relative to the inner bottom wall of the annular water tank 1, the silt deposited on the inner bottom wall of the annular water tank 1 is scraped off from its original position, so that the silt flows out of the inner bottom wall of the annular water tank 1. By controlling the output of the drive motor, the drag plate 21 is made to push the silt to gather at the discharge port 3. Then control the first electric valve inside the discharge pipe 31 inserted into the discharge port 3 to open. The silt gathered above the discharge port 3 flows downward with the liquid water through the discharge pipe 31 and is finally collected by the receiving box 32 below the discharge pipe 31. After the drag plate 21 completely scrapes the silt deposited in the annular water tank 1 and discharges it through the discharge port 3, control the first electric valve to close. The above process of cleaning the silt deposited in the annular water tank 1 is completed by the drag plate 21 located inside the annular water tank 1, replacing manual cleaning inside the annular water tank 1. Among them, after the first electric valve in the discharge pipe 31 is opened, the silt gathered above the discharge port 3 will flow downward with the liquid water. At this time, start the vibrator 33. The vibrator 33 vibrates on the surface of the discharge pipe 31, making the discharge pipe 31 vibrate synchronously, and the discharge port 3 of the annular water tank 1 connected to the discharge pipe 31 vibrates synchronously. Under the action of the vibration force, the silt gathered above the discharge port 3 accelerates through the discharge pipe 31. Among them, when the drag plate 21 scrapes the silt deposited on the inner bottom wall of the annular water tank 1, the air extraction pump 23 is started. The air extraction pump 23 jets air to the air jet head 22 through the conduit 24. The air jet head 22 jets the air flow towards the surface of the drag plate 21. When the air flow enters the liquid water, it drives the liquid water. The driven liquid water acts on the surface of the drag plate 21 to prevent the silt from adhering and accumulating on the surface of the drag plate 21.

[0043] After the sludge enters the inside of the material receiving box 32 along with the liquid water, when the sludge settles to the bottom of the material receiving box 32, the liquid extraction pump 7 is started, and the input end of the liquid extraction pump 7 pumps the liquid water above the sludge; after the sludge settles to the inside of the material receiving box 32, the second telescopic rod 41 is started, and the second telescopic rod 41 drives the partition plate 4 to move into the material receiving box 32 through the first linkage frame 42, and stops after the pair of partition plates 4 are butted. After the partition plates 4 are butted, the sludge is sealed below, and the liquid water is above the partition plates 4. When the liquid water in the material receiving box 32 is extracted by the liquid extraction pump 7; when there is too much sludge sediment in the material receiving box 32 and needs to be cleaned, during the cleaning, the third telescopic rod 5 is started, and the third telescopic rod 5 drives the scraper 52 to move into the material receiving box 32 through the second linkage frame 51. At the same time, the fourth telescopic rod 53 is started, and the fourth telescopic rod 53 drives the scraper 52 on the other side to move out of the material receiving box 32 through the third linkage frame 54, so that the scraper 52 opens the docking hole penetrating through the side of the material receiving box 32, and the scraper 52 on the other side pushes the sludge deposited at the bottom of the material receiving box 32 to move, and then flows out of the material receiving box 32 through the docking hole, completing the cleaning of the sludge in the material receiving box 32; the sludge flowing out of the material receiving box 32 is received by the receiving plate 6, and the staff only needs to collect the sludge on the receiving plate 6, which is convenient for the staff to collect the sludge flowing out of the material receiving box 32.

[0044] After the sludge on one side of the discharge port 3 in the annular water tank 1 is pushed by the drag plate 21 and gathers above the discharge port 3, it is necessary to move the drag plate 21 in the reverse direction so that the sludge on the other side of the discharge port 3 is also gathered above the discharge port 3. When the drag plate 21 moves away from the discharge port 3, the fifth telescopic rod 82 is started first, and the fifth telescopic rod 82 drives the blocking plate 81 to move into the annular water tank 1 through the fourth linkage frame 83. The blocking plate 81 moves attached to the surface of the drag plate 21, isolating the drag plate 21 from the sludge gathered above the discharge port 3. After that, when the drag plate 21 moves, the sludge gathered on one side of the discharge port 3 is blocked, so that when the drag plate 21 moves in the annular water tank 1, the sludge gathered at the discharge port 3 is difficult to be driven and diffused by the surging liquid water; after the blocking plate 81 restricts the sludge above the discharge port 3, there may be residues when the sludge is discharged along with the liquid water between the pair of blocking plates 81. Therefore, a water tank 84 is provided. When the liquid water between the pair of blocking plates 81 drains out, the second electric valve inside the water outlet pipe 85 is opened, and the water tank 84 sprays liquid water into the annular water tank 1 through the water pump inside the water outlet pipe 85. The liquid water drives the remaining sludge above the discharge port 3 to flow downward again; the liquid water sprayed out by the water outlet pipe 85 is received by the inclined plate 86 and then sprayed out. The sprayed liquid water is in the downward direction after being received by the inclined plate 86, flushing the remaining sludge on the inner bottom wall of the annular water tank 1, accelerating the flow of the remaining sludge along with the liquid water, and further optimizing the cleaning efficiency of the remaining sludge.

[0045] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
