Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution as follows: Figure 2 and Figure 3 As shown in this embodiment, a hydraulic reciprocating sludge scraper includes a water tank body 1 and two mounting bases 4. The two mounting bases 4 are detachably connected to the outer walls of both sides of the water tank body 1. A transmission assembly 5 is installed between the two mounting bases 4. The transmission assembly 5 includes two slide rails 501 fixedly connected between the two mounting bases 4, and both slide rails 501 are horizontally arranged. The two slide rails 501 are slidably fitted with the same mounting frame 502. A vertically arranged hydraulic cylinder 1 503 is fixedly installed on the inner wall of the bottom of the mounting frame 502. A horizontally arranged connecting assembly 6 is installed at the output end of the hydraulic cylinder 1 503, and a mounting bracket 2 is installed at the bottom of the connecting assembly 6. A hydraulic cylinder 2 504 is fixedly installed on one side of the outer wall of the mounting base 4, and the hydraulic cylinder 2 504 is horizontally arranged. The output end of the hydraulic cylinder 2 504 is fixedly connected to one side of the outer wall of the mounting frame 502.

[0025] The mounting bracket 2 has several equally spaced scrapers 3 fixedly connected inside, and all scrapers 3 are set in a vertical position.

[0026] Start the hydraulic cylinder 2 504 on the outside of the mounting base 4. The output end of the hydraulic cylinder 2 504 drives the mounting frame 502 and the hydraulic cylinder 1 503 to move horizontally. Then the mounting frame 2 will move horizontally towards the sludge collection trough. The scraper 3 at the bottom of the mounting frame 2 can push the sludge a distance. The sludge at the front is driven to fall into the sludge collection trough. Then start the hydraulic cylinder 1 503 inside the mounting frame 502. The output end of the hydraulic cylinder 1 503 drives the mounting frame 2 to move upward through the connecting component 6. The scraper 3 will also move away from the sludge. Then control the hydraulic cylinder 2 504 to extend. Multiple scrapers 3 will be driven away from the sludge again. Finally, control the hydraulic cylinder 1 503 to drive the scraper 3 back to the position ready for the next sludge scraping. By repeating this process, the sludge can be continuously cleaned.

[0027] like Figure 3 As shown, each of the several scrapers 3 has a through hole 7 rotatably connected to one side of its outer wall via a hinge, and each of the several scrapers 3 has a sealing plate 8 inside, with the several through holes 7 covering the outside of the several sealing plates 8 respectively.

[0028] When the scraper 3 moves away from the sludge collection trough of the water tank body 1, the through hole 7 is hinged to one side of the scraper 3, and water and sludge can pass through the sealing plate 8 to push the through hole 7 to flip, which effectively reduces the effect of the scraper 3 stirring up the sludge. When the scraper 3 moves in the opposite direction, the through hole 7 is blocked by the scraper 3 and cannot flip, so the sludge and water cannot pass through the sealing plate 8, which helps to ensure the sludge scraping effect.

[0029] As Figure 3 and Figure 4 As shown in the figure, the connecting assembly 6 includes a mounting plate 601 fixedly connected to the output end of the hydraulic cylinder 503, two horizontally arranged slide rods 602 are fixedly connected inside the mounting plate 601, two moving blocks 603 are slidably sleeved on the two slide rods 602, and one connecting frame 605 is hinged to the bottom of each moving block 603. The mounting frame 2 is hinged to the bottom of the two connecting frames 605.

[0030] A bidirectional screw rod 604 is rotatably connected inside the mounting plate 601 through a bearing, and the two moving blocks 603 are threadedly sleeved on the threaded outer portions of both ends of the bidirectional screw rod 604. A motor 606 is fixedly installed on one side outer wall of the mounting plate 601, and the output end of the motor 606 is coaxially fixed with one end of the bidirectional screw rod 604.

[0031] With the increase of use time, the thickness of the sludge attached to the outer surface of the mounting frame 2 and the scraper 3 increases, and the mud scraping effect will also decrease. The motor 606 on the outside of the mounting plate 601 can be started, the output end of the motor 606 drives the bidirectional screw rod 604 to rotate, and the two moving blocks 603 sleeved on the outside of the slide rod 602 are driven by the bidirectional screw rod 604 to move closer to each other. Since one end of the bottom of the connecting frame 605 is limited and fixed, when the top end thereof moves, the height of the connecting frame 605 in the vertical direction decreases, thereby driving the mounting frame 2 and the scraper 3 to move to the top position, facilitating cleaning, and without the need for workers to enter the bottom of the pool.

[0032] As Figure 3 shown, the thread angle of the thread grooves at both ends of the bidirectional screw rod 604 is smaller than the equivalent friction angle, so that it has self-locking property.

[0033] As Figure 3 shown, the mounting plate 601 is fixedly connected with a reinforcing block on the top inner wall, and the bidirectional screw rod 604 is rotatably connected with the reinforcing block through a bearing, which can activate the effect of reinforcing the bidirectional screw rod 604, thereby avoiding the bending of the moving block 603 when it moves to the middle position of the bidirectional screw rod 604.

[0034] The utility model provides a kind of hydraulic reciprocating mud scraper, specific working principle as follows:

[0035] When the device works, the hydraulic cylinder two 504 outside the mounting seat 4 is started, the output end of the hydraulic cylinder two 504 drives the mounting frame 502 and the hydraulic cylinder one 503 to translate, then the mounting frame 2 will translate towards the sludge collecting groove, the scraper 3 at the bottom of the mounting frame 2 can push the sludge to one end distance, the sludge at the forefront is driven to fall into the sludge collecting groove, then the hydraulic cylinder one 503 inside the mounting frame 502 is started, the output end of the hydraulic cylinder one 503 drives the mounting frame 2 to move up through the connecting assembly 6, the scraper 3 will also move away from the sludge, then the hydraulic cylinder two 504 is controlled to extend, the plurality of scrapers 3 will be driven to move away from the sludge, finally the hydraulic cylinder one 503 is controlled to drive the scraper 3 to return to the position ready for the next time of scraping sludge, thus reciprocating, the continuous cleaning of sludge can be realized, when the scraper 3 moves away from the sludge collecting groove of the pool body 1, because the through hole 7 is hinged at the position on one side of the scraper 3, water and sludge can pass through the sealing plate 8 to push the through hole 7 to overturn, which effectively reduces the effect of the scraper 3 on the sludge, when the scraper 3 moves reversely, the through hole 7 is blocked by the scraper 3 and cannot overturn, the sludge and water cannot pass through the sealing plate 8, which is beneficial to ensure the effect of sludge scraping, with the increase of the use time, the thickness of the sludge attached to the outer surface of the mounting frame 2 and the scraper 3 increases, the effect of sludge scraping will also decrease, the motor 606 outside the mounting plate 601 can be started, the output end of the motor 606 drives the bidirectional screw rod 604 to rotate, the two moving blocks 603 sleeved outside the sliding rod 602 will be driven by the bidirectional screw rod 604 to move close to each other, because the bottom end of the connecting frame 605 is limited and fixed, when the top end thereof moves, the height of the connecting frame 605 in the vertical direction decreases, thereby driving the mounting frame 2 and the scraper 3 to move to the top position, which is convenient for cleaning, and personnel need not enter the pool bottom.

[0036] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
