DETAILED DESCRIPTION

[0034] like Figure 1-Figure 4 As shown, a cleaning device and a cleaning method for a water conservancy project include two vertical plates 1, a floating plate 2 is fixedly installed on the outer side of the vertical plates 1, a top plate 9 and a bottom plate 12 are fixedly arranged between the two vertical plates 1, and the bottom plate 12 is located below the top plate 9, and a storage chamber for accommodating garbage is formed between the top plate 9 and the bottom plate 12, and a second square tube 10 is elastically arranged at one end of the top plate 9, and the second square tube 10 is an arc-shaped structure as a whole, one end of which is located between the top plate 9 and the bottom plate 12, and the other end of which is elastically arranged with a first square tube 13;

[0035] A slide plate 11 is slidably arranged between the top plate 9 and the bottom plate 12, and the slide plate 11 is located at one end of the second square tube 10 away from the first square tube 13. When garbage enters the storage chamber from the second square tube 10, the slide plate 11 will be squeezed to slide between the top plate 9 and the bottom plate 12. Both ends of the first square tube 13 and the second square tube 10 are opened.

[0036] A connecting shaft 6 is provided on one side of the first square tube 13 away from the top plate 9, both ends of the connecting shaft 6 pass through the vertical plate 1 and are rotatably connected thereto, and a filter plate 5 is provided at the connecting shaft 6, the filter plate 5 passes through the connecting shaft 6 along the radial direction of the connecting shaft 6 and is slidably matched therewith, and a pressure strip 4 is fixedly provided at the top and bottom ends of the filter plate 5;

[0037] A baffle 7 is fixedly arranged between the two vertical plates 1. The baffle 7 can be made of materials such as plastic or rubber. The baffle 7 is located on the side of the first square tube 13 away from the connecting shaft 6. When the filter plate 5 is in a vertical state, only a small gap will be left between the end of the pressure strip 4 and the baffle 7. At this time, the front and rear vertical plates 1, the baffle 7 and the filter plate 5 enclose a compression chamber. As the filter plate 5 moves downward relative to the connecting shaft 6, the pressure strip 4 on the filter plate 5 is conducive to squeezing the garbage in the compression chamber into the first square tube 13, and then squeezed into the space between the top plate 9 and the bottom plate 12 through the second square tube 10 for storage. In actual application, a rubber pad can be fixedly arranged on the outside of the slide plate 11 to increase the friction between the slide plate 11 and the top plate 9 and the bottom plate 12, so that the garbage can be further compressed in the storage chamber, which is conducive to storing more garbage.

[0038] A guide plate 19 is provided on one side of the top of the first square tube 13 close to the connecting shaft 6, and a lifting assembly connected to the guide plate 19 is provided on the first square tube 13. When the filter plate 5 rotates to cause the pressure strip 4 to pass over the first square tube 13, the lifting assembly drives the guide plate 19 to move upward, so that the guide plate 19 is in an inclined state and contacts with the rotating filter plate 5, so that the garbage attached to the filter plate 5 can flow into the compression chamber along the guide plate 19.

[0039] like Figure 3-Figure 10 As shown, the lifting assembly includes a slider 21 that is slidably matched with the first square tube 13. A strip groove is provided on one side of the top of the first square tube 13 near the connecting shaft 6. The slider 21 is slidably arranged at both ends of the strip groove. Specifically, a vertical shaft 23 is fixedly arranged on the bottom surface of the strip groove. The vertical shaft 23 passes through the slider 21 and is slidably connected thereto. A support spring 22 is sleeved on the outer side of the vertical shaft 23. The support spring 22 is connected between the slider 21 and the bottom surface of the strip groove. In addition, a baffle is fixedly arranged on the top of the vertical shaft 23 to prevent the slider 21 from being separated from the vertical shaft 23.

[0040] The guide plate 19 is located between the two sliders 21. Fig. 9 As shown, a round shaft 26 is fixedly provided near the bottom end of both sides of the guide plate 19, and the round shaft 26 extends into the slider 21 and is connected thereto through a coil spring 25;

[0041] Furthermore, a slot 30 is provided on the outer circumferential surface of the vertical shaft 23, and a block 27 that cooperates with the slot 30 is elastically provided on the side of the slider 21 away from the guide plate 19. When the block 27 pops out and is inserted into the slot 30, the slider 21 is locked with the vertical shaft 23. A first magnet 28 is fixedly provided on the end of the block 27 away from the slot 30, and a second magnet 31 is fixedly embedded on the inner wall of the vertical plate 1. The second magnet 31 is a strip-shaped structure. The first magnet 28 and the second magnet 31 are collinearly arranged in the vertical direction, and the opposite sides of the first magnet 28 and the second magnet 31 have the same magnetic poles. First through grooves connected to the strip grooves are provided on the end surfaces of both ends of the first square tube 13 to facilitate the cooperation between the first magnet 28 and the second magnet 31.

[0042] The filter plate 5 is fixedly provided with protrusions 15 at positions near the pressure strip 4 on both sides. The outer side of the protrusion 15 is an arc surface. When the protrusion 15 on the filter plate 5 moves to the guide plate 19, the guide plate 19 can be driven to deflect in the vertical direction by the pressure of the protrusion 15 and finally contact the bottom surface of the pressure strip 4.

[0043] A guide plate 14 is elastically provided on one side of the pressure strip 4 close to the filter plate 5, and a plurality of latch teeth are integrally formed at the bottom of the guide plate 14. When the protrusion 15 squeezes the guide plate 19 to deflect in the vertical direction, the top of the guide plate 19 will be placed at the latch teeth on the bottom surface of the guide plate 14. At this time, as the pressure strip 4 moves downward, the guide plate 19 and the slider 21 can be driven to move downward. In this process, the guide plate 19 is squeezed by the side edges of the strip groove so that the guide plate 19 gradually rotates to a vertical state, and the guide plate 14 is set to avoid direct contact between the guide plate 19 and the bottom surface of the pressure strip 4 to generate a large friction force.

[0044] In actual use, in order to drive the connecting shaft 6 to rotate, a driven gear is fixedly sleeved on one end of the connecting shaft 6 passing through the vertical plate 1, and a motor is arranged on the side of the baffle 7 away from the first square tube 13. The motor is fixedly connected to the vertical plate 1, and the output end of the motor is connected to a driving shaft, the driving shaft passes through the vertical plate 1 and is fixedly provided with a driving gear 3, the driving gear 3 is meshed with the driven gear, and the driving shaft here is rotatably connected to the vertical plate 1, and this structure can drive the driven gear to rotate, thereby driving the connecting shaft 6 to rotate, and in order to drive the entire device to move on the water surface, a first propeller can be fixedly installed at the bottom of the floating plate 2, and a second propeller can be fixedly installed on the bottom surface of the bottom plate 12, the first propeller can be used to drive the device to walk on the water surface, and the second propeller can be used to drive the device to turn on the water surface, of course, the first propeller and the second propeller here can be operated by remote control, and the specific control structure is a mature technical means in the electrical field, which will not be described in detail here;

[0045] When the whole device is located on the water surface, the floating plate 2 is helpful to support the device, and the inner side of the vertical plate 1 is provided with a baffle 7. When the filter plate 5 is in a position such as Figure 4 In the state shown in FIG. 1 , the filter plate 5 is gradually deflected upward as the connecting shaft 6 rotates. During this process, the filter plate 5 can lift the garbage accumulated between the two vertical plates 1 upward and away from the water surface. Figure 3 and Figure 6 As shown, when the filter plate 5 gradually rotates upward, the top of the guide plate 19 will fit with the filter plate 5. Afterwards, when the filter plate 5 rotates, it will squeeze the guide plate 19, thereby causing the guide plate 19 to gradually rotate toward the baffle 7. Through the provided guide plate 19, when the garbage slides off the filter plate 5, it can pass through the guide plate 19 into the first square tube 13. When the guide plate 19 rotates to a vertical state, the pressure strip 4 is located on one side of the baffle 7. At this time, under the action of the gravity of the pressure strip 4, the filter plate 5 can be driven to move downward relative to the connecting shaft 6. As the pressure strip 4 moves downward The movement can compress the garbage in the compression chamber into the first square tube 13, and then enter the storage chamber through the second square tube 10. The sliding plate 11 is provided, and the friction between the sliding plate 11 and the top plate 9 and the bottom plate 12 is used to compress the garbage well in the storage chamber. In addition, when the filter plate 5 moves downward relative to the connecting shaft 6, since the guide plate 19 is always in contact with the filter plate 5, the guide plate 19 can also remove the sundries such as branches stuck on the filter plate 5, thereby preventing the garbage from being retained on the filter plate 5 and affecting the use of the filter plate 5.

[0046] When the protrusion 15 on the filter plate 5 slides to the guide plate 19, the pressure of the protrusion 15 on the guide plate 19 causes the guide plate 19 to deflect in the direction close to the baffle 7 and finally contact with the guide plate 14 at the bottom of the layer 4. Afterwards, when the layer 4 continues to move downward, it can drive the guide plate 19 and the slider 21 to slide downward along the strip groove. The squeezing of the guide plate 19 by the side edges of the strip groove is conducive to the guide plate 19 gradually rotating to a vertical state and being stored in the strip groove. In this process, the guide plate 19 will drive the guide plate 14 at the bottom of the layer 4 to deflect, thereby avoiding In order to avoid generating a large friction force between the guide plate 19 and the pressure strip 4, when the guide plate 19 is stored in the strip groove, the pressure strip 4 will contact the top end surface of the first square tube 13 and drive it to move downward, so that the first magnet 28 on the clamping block 27 can be aligned with the second magnet 31 on the vertical plate 1. Under the repulsive force between the first magnet 28 and the second magnet 31, the clamping block 27 can be driven to move in the direction of the vertical axis 23 and finally inserted into the clamping groove 30, so as to lock the slider 21 and the vertical axis 23, so that the slider 21 and the guide plate 19 are stably placed in the strip groove;

[0047] When the pressure strip 4 continues to rotate with the connecting shaft 6, the pressure strip 4 will squeeze the first square tube 13 and continue to drive it to move downward. When the pressure strip 4 passes over the first square tube 13, the first square tube 13 bounces upward. When the first square tube 13 moves upward to the initial position, the first magnet 28 and the second magnet 31 are staggered. At this time, the block 27 will be separated from the slot 30, thereby driving the slider 21 to slide upward along the strip slot through the pressure of the support spring 22, and the guide plate 19 is also deflected outward under the action of the coil spring 25 so as to fit with the filter plate 5 rotating upward. The above process can be repeated to continuously clean the garbage between the two vertical plates 1.

[0048] In summary, in this device, a filter plate 5 is slidably arranged on the connecting shaft 6, and the rotation of the filter plate 5 can continuously collect the garbage between the two vertical plates 1. By arranging the pressure strip 4 on the filter plate 5, on the one hand, it can prevent the garbage from falling off the filter plate 5 when the filter plate 5 rotates upward to salvage the garbage. On the other hand, when the filter plate 5 moves downward relative to the connecting shaft 6, the pressure strip 4 can be used to compress the garbage in the compression chamber, so that the garbage is compressed in the storage chamber through the first square tube 13 and the second square tube 10, which is beneficial to increase the storage capacity of the garbage. In addition, when the filter plate 5 moves downward relative to the guide plate 19, the guide plate 19 can be used to clean up the debris stuck on the filter plate 5, so that the filter plate 5 can be used normally.
