[0032] The water channel 1 is slidingly connected with a floating block 11 capable of floating up under the water, when the floating block 11 is lowered to a specified position, the motor 3 can be driven to work, so that the scraper 7 slides along the surface of the filter plate 2 to realize the cleaning of the filter plate 2, the scraper 7 is rotationally connected with a brush ball, the brush ball can roll along the surface of the filter plate 2, and when the scraper 7 moves, the brush ball can be rolled to better realize the cleaning of the filter plate 2.

[0033] The water channel 1 is connected with a sliding plate 13, the floating block 11 is provided with a slot 14, the sliding plate 13 is fixedly connected with a sliding sleeve 15, the sliding sleeve 15 is slidingly connected with a plug rod 17 capable of sliding into the slot 14, when the plug rod 17 slides into the slot 14, the floating block 11 can be limited, and the position of the floating block 11 is limited.

[0034] The plug rod 17 is connected with the sliding plate 13 through a spring, the spring is sleeved on the plug rod 17, the left end of the spring is connected with the plug rod 17, and the right end of the spring is connected with the sliding plate 13, in the initial state, the slot 14 is higher than the plug rod 17, at this time, the plug rod 17 slides along the surface of the floating block 11, and the spring is in a stretched state, when the floating block 11 is lowered, the elastic force of the spring can make the plug rod 17 slide into the slot 14.

[0035] The sliding plate 13 is connected with a press switch 16 controlling the working of the motor 3, when the plug rod 17 slides into the slot 14, at this time, the plug rod 17 presses the press switch 16 to make the motor 3 work.

[0036] The pressing switch 16 is specifically a pressing spring switch, which is usually composed of a pressing button, a spring, a fixed seat and a conductive contact. The pressing button is usually made of plastic or metal material and has certain pressing performance and mechanical strength. The spring functions to automatically reset the button and ensure the elasticity of pressing. The fixed seat is used to fix the button and the spring to ensure that their positions do not change. The conductive contact is a key part of the circuit and is connected through the pressing button to make the contact connect or disconnect the circuit, thereby realizing the function of the switch.

[0037] Under the elastic force of the spring, when the plug rod 17 and the button are in contact, the button is pressed down at this time, the button applies force to the inside to compress the spring. In the process of pressing the button, the conductive contact is in contact with another contact to make the circuit closed, the current can flow, and the motor 3 works.

The push rod 8 is provided with an inclined surface on one side. Under the action of the inclined surface, the scraper 7 can drive the push rod 8 to move towards the floating block 11.

[0040] The push rod 8 is connected with a magnet 10 which has an attractive effect on the plug rod 17. The tension spring 9 is sleeved on the push rod 8. The left end of the tension spring 9 is connected with the drain tank 6, and the right end of the tension spring 9 is connected with the push rod 8.

The distance that the scraper 7 drives the push rod 8 to move is greater than the length that the plug rod 17 slides into the insertion slot 14. The magnetic force of the magnet 10 is greater than the elastic force of the spring. Therefore, when the magnet 10 moves to the side of the plug rod 17, the magnetic force of the magnet 10 can make the plug rod 17 move out of the insertion slot 14,

[0043] Embodiment two

[0044] Reference to the accompanying drawings Figure 4 The other structures are the same as those in embodiment one, and the difference lies in that, in this embodiment, the reset of the scraper is considered.

[0045] Since the feedback control and the holding force are cancelled in embodiment one, the precision and stability of the servo motor can be affected, therefore, in this embodiment, the output shaft of the motor 3 is fixedly connected with a first gear 20, the water channel 1 is slidingly connected with a push rod 22, the push rod 22 is rotatably connected with a second gear 21, the rope wheel 4 is fixedly connected with a third gear 24, the second gear 21 is located between the third gear 24 and the first gear 20, and the two sides can be engaged with or disengaged from the third gear 24 and the first gear 20.

[0046] The water channel 1 is connected with an electromagnet 23, the electromagnet 23 has an attraction effect on the push rod 22, when the press switch 16 is pressed, the electromagnet 23 is electrified, so that the two ends of the second gear 21 are engaged with the third gear 24 and the first gear 20 respectively, when the electromagnet 23 is powered off, under the action of gravity, or by increasing the reset spring, the second gear 21 is disengaged from the third gear 24 and the first gear 20, at this time, the rope wheel 4 can rotate freely, so as to facilitate the reset of the scraper 7.

[0047] The specific working process is as follows: the filter plate 2 filters the water in the water channel 1, at this time, the garbage is intercepted on the surface of the filter plate 2, under the action of gravity, the garbage will slide into the scraper 7, by rotating the screw rod 12, the height of the sliding plate 13 is adjusted, so that when the water level is at what height, the motor 3 will rotate, the filter plate 2 is cleaned, after the height of the sliding plate 13 is adjusted, when the filter plate 2 is blocked, at this time, the water level on one side of the float 11 is lowered, the float 11 is lowered.

[0048] When the float 11 drops to the slot 14 moves to the side of the plug rod 17, at this time the spring force makes the plug rod 17 slide into the slot 14, the plug rod 17 presses the press switch 16, the motor 3 and the electromagnet 23 are powered to work, the electromagnet 23 attracts the push rod 22, the second gear 21 is meshed with the third gear 24 and the first gear 20 respectively, the motor 3 drives the first gear 20 to rotate, the first gear 20 drives the third gear 24 to rotate through the second gear 21, the third gear 24 drives the rope wheel 4 to rotate, at this time the rope wheel 4 drives the pull rope 5 to wind on the rope wheel 4, the pull rope 5 drives the scraper 7 to move, realizing the movement of the scraper 7 along the surface of the filter plate 2.

[0049] With the movement of the scraper 7, the scraper 7 cleans the garbage on the surface of the filter plate 2 and scrapes into the draining tank 6, the water in the garbage flows back into the water channel 1 through the water outlet hole of the draining tank 6, the scraper 7 drives the push rod 8 to move, the push rod 8 drives the magnet 10 to move, the magnet 10 moves to the side of the plug rod 17 at this time, the plug rod 17 moves out of the slot 14, releasing the limiting of the float 11, at this time the float 11 rises with the increase of the water level, the plug rod 17 slides along the surface of the float 11.

[0050] The plug rod 17 no longer presses the press switch 16, the motor 3 and the electromagnet 23 are powered off, under the action of gravity, or by increasing the reset spring, the second gear 21 is disengaged from the third gear 24 and the first gear 20, at this time the rope wheel 4 can rotate freely, under the action of gravity, the scraper 7 is reset, and the tension spring 9 drives the push rod 8 to move.

[0051] Because the elastic force of the tension spring 9 is greater than the magnetic force of the magnet 10, the tension spring 9 can drive the push rod 8 to reset, so that the magnet 10 and the plug rod 17 no longer cooperate, so that the whole device can be reset, facilitating the next round of filter plate 2 cleaning work.

[0052] It should be noted that the slide plate 13 is provided with a sliding hole, the plug rod 17 can only move in the sliding hole, under the elastic force of the tension spring 9, at this time there is enough distance between the magnet 10 and the plug rod 17, under the action of the distance, the magnetic force of the magnet 10 is small enough, so it will not pull the plug rod 17, the spring can drive the plug rod 17 to slide into the slot 14,
