As shown in fig. 1 to 5, the present invention provides a fishyard tail water filtering apparatus with an automatic cleaning function, which comprises a water storage tank 100, a filtering assembly 200, a first driving device 300 and a second driving device 400.

Wherein, the bottom surface of the water storage tank 100 is in a semicircular arc shape and the top is opened. Note that the water storage tank 100 is connected to a water supply system. Preferably, the radius of the bottom surface of the sump 100 is equal to the radius of rotation of the filter assembly.

The number of the filter assemblies 200 is two, the two filter assemblies 200 are respectively installed at both sides of a center line of the bottom surface of the water storage tank 100, and any one of the filter assemblies 200 has two working positions, i.e., a first working position and a second working position.

When the filter assembly 200 is in the first operating position, the filter assembly 200 is in an operating state for filtering water. When the filter assembly 200 is in the second operating position, the filter assembly 200 is in an idle state for cleaning the filter assembly 200 of impurities.

When one filter assembly 200 is in the first operating position, the other filter assembly 200 is in the second operating position. Thus, when one filter assembly 200 is cleaned, the other filter assembly 200 is still in working state, and the filtering efficiency is not influenced. Preferably, the first operating position of the filter assembly 200 is at the bottom of the reservoir 100 and the second operating position is at the top of the reservoir 100.

The first driving means 300 are used to drive one filtering assembly 200 from the first operating position to the second operating position and the other filtering assembly 200 from the second operating position to the first operating position. Namely, the two filter assemblies 200 are driven to change the working positions, that is, the filter assembly 200 which needs to clean impurities is driven to the second working position, and meanwhile, the filter assembly 200 which is cleaned of impurities is driven to the first working position.

The second driving device 400 is used for driving the filter assembly 200 in the second working position to rotate so as to clean impurities on the surface of the filter assembly 200. Specifically, the second driving device 400 drives the filter assembly 200 to rotate, and impurities are separated from the surface of the filter assembly 200 by the centrifugal force, thereby cleaning the filter assembly 200.

In one embodiment, the first driving device 300 includes a first motor 310, a rotating bracket 320, and a rotating shaft 330.

Wherein, the first motor 310 is installed at one side of the water storage tank 100 and is fixedly connected with the water storage tank 100. And the power output shaft of the first motor 310 is coaxially arranged with the center line of the bottom surface of the water storage tank 100 and is rotatably connected with the water storage tank 100.

The rotating bracket 320 is installed in the water storage tank 100 and is fixedly connected with a power output shaft of the first motor 310.

The number of the rotating shafts 330 is two, the two rotating shafts 330 are respectively installed at two ends of the rotating bracket 320 and rotatably connected with the rotating bracket 320, and one ends of the two rotating shafts 330 far away from the center line of the rotating shaft 330 of the rotating bracket 320 are respectively connected with one filter assembly 200.

Thus, the working positions of the two filter assemblies 200 can be changed every time the first motor 310 drives the rotary bracket 320 to rotate by 180 degrees.

The first driving device 300 with this structure has a simple structure and is easy to control.

In one embodiment, the second driving device 400 includes a second motor 410, a first electric telescopic rod 420, and a driving friction wheel 430.

Wherein the second motor 410 is installed at the other side of the sump 100 and is slidably connected to the sump 100.

The first electric telescopic rod 420 is used for driving the second motor 410 to do reciprocating linear motion. Specifically, the power output end of the first electric telescopic rod 420 is connected with the second motor 410. Thus, the second motor 410 can be driven to reciprocate by controlling the extension or contraction of the first electric telescopic rod 420.

The driving friction wheel 430 is installed on a power output shaft of the second motor 410, and the driven friction wheel 440 is installed at one end of the rotating shaft 330 facing the rotating bracket 320, so that when the first electric telescopic rod 420 extends, the driving friction wheel 430 and the driven friction wheel 440 are abutted against each other.

Thus, when the first motor 310 drives the filter assembly 200 to move to the second working position, the first motor 420 is first extended to drive the second motor 410 to move, so that the driving friction wheel 430 moves to a direction close to the driven friction wheel 440, and the driving friction wheel 430 and the driven friction wheel 440 are interfered with each other. Then, the second motor 410 rotates to rotate via the driving friction wheel 430 and the driven friction wheel 440, so as to drive the filter assembly 200 to rotate, and impurities on the surface of the filter assembly 200 are thrown out by the centrifugal force, so that the filter assembly 200 is cleaned.

In one embodiment, the filter assembly 200 includes a filter support 210 and a first valve assembly 230.

Wherein, the side of the centre of a circle line of the bottom surface that deviates from the aqua storage tank 100 of filter screen support 210 is the sphere form, and the radius of sphere form suits with the radius of rotation of filter assembly 200, and the periphery of filter screen support 210 is provided with a plurality of first installing ports, and first installing port department is fixed and is provided with filter screen 220.

The first valve assembly 230 includes a first permanent magnet 231 and a first return spring 232.

Wherein, one side of the filter screen bracket 210, which is far away from the circle center line of the bottom surface of the water storage tank 100, is provided with a first mounting cavity 201, the side wall of one end of the first mounting cavity 201, which is far away from the circle center line of the bottom surface of the water storage tank 100, is provided with a plurality of first water outlets 202, one end of the first mounting cavity 201, which is far away from the circle center line of the bottom surface of the water storage tank 100, is provided with a second water outlet 203, a first permanent magnet 231 is slidably mounted in the first mounting cavity 201 and keeps sealed with the first mounting cavity 201, a first reset spring 232 is mounted in the first mounting cavity 201 and is positioned at one end of the first permanent magnet 231, which faces the circle center line of the bottom surface of the water storage tank 100, and in a natural state, the first reset spring 232 has a.

Thus, when the first permanent magnet 231 is located at one end of the first installation cavity 201 away from the center line of the bottom surface of the water storage tank 100, the first permanent magnet 231 blocks the first water outlet 202 and the second water outlet 203.

In one embodiment, a second valve assembly 500 is further included, the second valve assembly 500 being mounted on a side of the filter assembly in the first operating position away from the axial center line of the rotating bracket 320 and corresponding to the first valve assembly 230, the second valve assembly 500 including a valve body 510, a second permanent magnet 520, and a second return spring 530.

Wherein, the bottom of the water storage tank 100 is provided with a second mounting opening, the valve body 510 is fixedly mounted at the second mounting opening and keeps sealed with the water storage tank 100, and one side of the valve body 510 facing the filter assembly 200 is adapted to the spherical shape. This will not affect the engagement of filter assembly 200 with second valve assembly 500 regardless of how much second drive 400 rotates filter assembly 200. It should be noted that when filter assembly 200 is in the first operating position, filter assembly 200 remains sealed to second valve assembly 500.

The valve body 510 is provided with a second mounting cavity 501, one end of the second mounting cavity 501 facing the filter assembly 200 is provided with a third water outlet 502, the side wall of the one end of the second mounting cavity 501 facing the filter assembly 200 is provided with a plurality of fourth water outlets 503, and the second permanent magnet 520 is slidably mounted in the second mounting cavity 501 and sealed with the second mounting cavity 501.

The second return spring 530 is installed in the second installation cavity 501 and located at an end of the second permanent magnet 520 facing away from the filter assembly 200, and naturally, the second return spring 530 has a tendency to move the second permanent magnet 520 closer to the filter assembly 200. Thus, when the second permanent magnet 520 is positioned at an end of the second mounting cavity 501 facing the filter assembly 200, the third water outlet 502 and the fourth water outlet 503 are blocked.

And when the filter assembly 200 is in the first working position, the opposite sides of the first permanent magnet 231 and the second permanent magnet 520 have the same magnetic poles. Thus, when the filter assembly 200 is in the first operating position, the first permanent magnet 231 and the second permanent magnet 520 have the same magnetic poles on opposite sides thereof, according to the principle that like poles repel each other. Under the action of the repulsive forces of the first permanent magnet 231 and the second permanent magnet 520, the first permanent magnet 231 and the second permanent magnet 520 respectively overcome the elastic forces of the first return spring 232 and the second return spring 530 to move towards the directions away from each other, so that the first permanent magnet 231 opens the first water outlet 202 and the second water outlet 203, the second permanent magnet 520 opens the third water outlet 502 and the fourth water outlet 503, and water in the water storage tank 100 enters the filter assembly 200 through the filter screen 220, enters the second water outlet 203 through the first water outlet 202 after being filtered by the filter assembly 200, then enters the third water outlet 502, and finally flows out of the fourth water outlet 503.

The second valve assembly 500 of this structure is matched with the first valve assembly 230 to complete the automatic opening and closing of the first water outlet 202, the second water outlet 203, the third water outlet and the fourth water outlet 503 without additional energy such as electric energy.

In one embodiment, the driving friction wheel 430 is slidably connected to the power output shaft of the second motor 410 through a shaft sleeve 450, a third return spring 460 is disposed in the shaft sleeve 450, and the third return spring 460 has a tendency to move the shaft sleeve 450 away from the power output shaft of the second motor 410 in a natural state.

Thus, the driving friction wheel 430 and the driven friction wheel 440 can always keep interference under the elastic force of the third return spring 460.

In one embodiment, the device 600 for containing foreign matter further comprises two oppositely arranged containing units 610, wherein the containing units 610 comprise a box body 611 and a second electric telescopic rod 612.

The box body 611 is installed at one side of the filter assembly 200 at the second working position, one side of the box body 611 facing the filter assembly 200 is provided with an opening, and one side of the box body 611 facing the first motor 310 is provided with a groove adapted to the rotating shaft 330.

The second electric telescopic rod 612 is fixedly installed on a side of the box body 611 facing away from the filter assembly 200, and a power output shaft of the second electric telescopic rod 612 is fixedly connected with the box body 611.

Thus, when the first driving device 300 drives the filtering assembly 200 to be cleaned of impurities to move to the second working position, the two second electric telescopic rods 612 extend and drive the two cases 611 to approach and contact each other, so as to cover the filtering assembly 200 in the two cases 611. The second driving device 400 drives the filter assembly 200 to rotate, so as to throw out impurities on the surface of the filter assembly 200. The foreign substances are contained in the case 611 by the case 611, and thus are not returned to the water storage tank 100. After cleaning, the two second telescopic electric rods 612 are retracted to drive the two cases 611 away from each other, thereby exposing the filter assembly 200.

Preferably, the two housings 611 are kept sealed from each other when they are close to each other, and at least one of the housings 611 is provided with a water inlet (not shown in the drawings) and a water outlet (not shown in the drawings), the water inlet being connected to a clean water supply system. When the second driving device 400 drives the filter assembly 200 to rotate, water is sprayed into the box 611, so that the surface of the filter assembly 200 can be cleaned, and meanwhile, the mass of impurities can be increased due to the addition of the water, so that the centrifugal force is increased, and the cleaning effect is enhanced. And the sewage after cleaning flows out from the water outlet.

The working principle of the invention is as follows:

when the filter assembly 200 in the first working position works for a period of time and needs to be cleaned, the first driving device 300 drives the rotating bracket 320 to rotate 180 degrees, so that the two filter assemblies 200 can change working positions. The two second motorized telescoping rods 612 then extend and drive the two housings 611 toward each other and into contact to enclose the filter assembly 200 within the two housings 611. The second driving device 400 drives the filter assembly 200 to rotate, so as to throw out impurities on the surface of the filter assembly 200. The foreign substances are contained in the case 611 by the case 611, and thus are not returned to the water storage tank 100. After cleaning, the two second telescopic electric rods 612 are retracted to drive the two cases 611 away from each other, thereby exposing the filter assembly 200.

Such repetition of the above steps may allow cleaning of the filter assembly 200 without affecting the treatment of the water.
