[0039] In the present embodiment, the rainwater collection device is an agricultural water-saving rainwater collection device (hereinafter referred to as the collection device). Specifically, the collection device includes a water collecting box 1 and a filtering structure arranged on the water collecting box 1. The upper end of the water collecting box 1 is provided with an opening, and the filtering structure includes a first filter element 5 covering the opening, and a plurality of first filtering holes 52 are provided on the first filter element 5. A cleaning unit is also provided on the water collecting box 1, and the cleaning unit includes a cleaning plate 8 slidably arranged on the first filter element 5 along the left-right direction, and the size of the cleaning plate 8 in the front-to-back direction is adapted to the size of the first filter element 5 in the front-to-back direction. The cleaning unit also includes a driving mechanism, and the driving mechanism is used to drive the cleaning plate 8 to slide along the left-to-right direction.

[0040] like Figure 1, 2 As shown, the first filter element 5 is a filter plate, and the first filter hole 52 is arranged in the middle and right side of the filter plate. The left side of the filter plate is a plate-like structure without the first filter hole 52, and the cleaning unit is arranged on the plate-like structure on this side, which is convenient for the installation of the cleaning unit.

[0042] In other embodiments, when actual usage requirements are met, the cleaning chute 51 can be set on the front and rear sides of the water collecting box 1. At this time, the cleaning plate 8 is an inverted "concave" shape, and the inner side of the lower part of the cleaning plate 8 is slidably set in the cleaning chute 51 on the corresponding side. In this way, on the one hand, the cleaning plate 8 can slide along the cleaning chute 51, and on the other hand, it can prevent debris such as fallen leaves from falling into the cleaning chute 51 and polluting the cleaning chute 51.

[0043] In this embodiment, if Figure 2 As shown, the driving mechanism includes a mounting box 6 arranged on the left side of the cleaning plate 8, the bottom of the mounting box 6 is fixedly mounted on the filter plate, a multi-stage cylinder 7 is arranged in the mounting box 6, the axis of the multi-stage cylinder 7 extends in the left-right direction, the cylinder body of the multi-stage cylinder 7 is fixedly mounted in the mounting box 6, and the driving end of the multi-stage cylinder 7 extends rightward out of the mounting box 6 and is fixedly mounted on the left side of the cleaning plate 8. In this way, the cleaning plate 8 can be driven to slide in the left-right direction by driving the multi-stage cylinder 7, and the cleaning plate 8 is used to clean the debris falling on the first filter hole 52 of the filter plate, so as to avoid the first filter hole 52 from being blocked and affecting the water collection efficiency.

[0044] Of course, in other embodiments, the driving mechanism can also be a hydraulic cylinder, or in other embodiments, a synchronous wheel is rotatably installed on the left and right sides of the first filter element 5 through a mounting frame, and a synchronous belt is wound around the two synchronous wheels. The driving mechanism includes a driving motor that drives the synchronous wheel to rotate, and a through hole for the synchronous belt to pass through is provided on the cleaning plate 8, and the cleaning plate 8 is fixed to the synchronous belt. In this way, the driving motor can be used to drive the synchronous wheel to rotate, drive the synchronous belt to move, and then drive the cleaning plate 8 to slide.

[0045] In this embodiment, preferably, Figure 2As shown, the movable cover of the first filter element 5 is arranged on the upper opening of the water collecting box 1. The right end of the first filter element 5 is hingedly connected to the water collecting box 1 through a hinge shaft 17, and the axis of the hinge shaft 17 extends in the front-back direction. A dumping unit is also arranged on the water collecting box 1, and the dumping unit is used to drive the first filter element 5 to flip outward around the hinge shaft 17 and fall back.

[0046] Specifically, Figure 2 As shown, a mounting plate 9 is provided at the left side of the inner cavity of the water collecting box 1. The mounting plate 9 is an L-shaped plate, which includes a horizontal plate and a vertical plate fixed on the right side of the horizontal plate and extending upward. The horizontal plate is arranged above the bottom surface of the inner cavity of the water collecting box 1 at intervals, and the left side of the horizontal plate is fixedly connected to the left side of the inner cavity of the water collecting box 1. The size of the horizontal plate in the left-right direction is adapted to the left-right direction size of the plate-like structure on the left side of the first filter element 5 without the first filter hole 52, and the size of the horizontal plate in the front-to-back direction is adapted to the front-to-back direction size of the inner cavity of the water collecting box 1. The upper end of the vertical plate abuts against the lower end of the first filter element 5. In this way, the mounting plate 9 and the inner cavity of the water collecting box 1 can be used to enclose an installation cavity 91, and the part outside the installation cavity 91 constitutes a water storage cavity 12. When collecting rainwater, rainwater will not fall or splash into the installation cavity 91, so that the installation cavity 91 is kept dry and the components in the installation cavity 91 are prevented from being damaged by moisture.

[0047] A hydraulic rod 11 is arranged in the installation cavity 91, and the hydraulic rod 11 includes a mounting sleeve and a driving rod, wherein a hinge seat 10 is arranged at a position of the mounting plate 9 corresponding to the lower end of the mounting sleeve, and the lower end of the mounting sleeve is hingedly connected to the hinge seat 10 through a support rod 101, and the hinge axis of the mounting sleeve extends in the front-to-back direction.

The upper end of the driving rod is hingedly connected to the hinge seat 10, and its hinge axis extends in the front-back direction. In this way, when it is necessary to remove the debris on the first filter plate, the first filter element 5 can be lifted up by the hydraulic rod 11, so that the first filter element 5 is turned outward, and the first filter element 5 is tilted with the water collecting box 1, and the sliding of the cleaning plate 8 is coordinated to facilitate the falling and cleaning of the debris, thereby improving the cleaning efficiency and cleaning effect.

[0049] Preferably, in the present embodiment, a second filter element 13 is provided inside the water collecting box 1 at a position corresponding to the first filter element 5, the size of the second filter element 13 is adapted to the size of the first filter element 5, a plurality of second filter holes 131 are provided on the second filter element 13, and the mesh number of the second filter holes 131 is greater than the mesh number of the first filter holes 52, that is, the aperture of the second filter holes 131 is smaller than the aperture of the first filter holes 52, and the density of the second filter holes 131 is greater than that of the second filter holes 131.

[0050] Specifically, Figure 2 As shown, the second filter element 13 is a filter net, and the second filter element 13 is arranged above the bottom of the inner cavity of the water collecting tank 1 at intervals, and the left end of the second filter element 13 is fixedly connected to the right side of the vertical plate of the mounting plate 9, and the right end of the second filter element 13 is fixedly connected to the right side wall of the inner cavity of the water collecting tank 1. The second filter element 13 is arranged in this way, and the mesh number of the second filter hole 131 is larger than the mesh number of the first filter hole 52. The second filter element 13 can be used for secondary filtration to improve the filtration effect, reduce impurities in the water collecting tank 1, and avoid clogging of the irrigation pipe 2. Of course, in other embodiments, the second filter element can also be a filter plate, or a mesh filter sponge, etc. In other embodiments, the first filter element can also be a filter net.

[0051] In this embodiment, the left-right dimensions of the second filter element 13 are adapted to the left-right dimensions of the position of the first filter hole 52 set on the first filter element 5, so that rainwater falling from the first filter element 5 can fall on the second filter element 13 for secondary filtration, thereby improving the filtering effect.

[0052] Preferably, in this embodiment, a shock absorbing structure is also provided on the water collecting tank 1, and the shock absorbing structure includes a shock absorbing groove 141 opened on the upper end surface of the water collecting tank 1, a shock absorbing spring 15 is provided in the shock absorbing groove 141, and a shock absorbing block is provided at the upper end of the shock absorbing spring 15, and the position of the shock absorbing block corresponds to the lower end surface of the first filter plate.

[0053] Specifically, in this embodiment, if Figure 4 As shown, the shock absorbing groove 141 is provided at the left side of the upper end surface of the opening of the water collecting tank 1. The shock absorbing spring 15 extends vertically, and its lower end is fixedly connected to the bottom of the shock absorbing groove 141. The shock absorbing block is a rubber block 16, and the lower end of the rubber block 16 is fixedly connected to the upper end of the shock absorbing spring 15; the upper end extends out of the shock absorbing groove 141, and the shock absorbing block 16 is vertically slidably arranged in the shock absorbing groove 141.

[0054] Limiting holes are provided on both side walls of the damping groove 141, and matching limiting plates 161 are provided at the positions corresponding to the limiting holes on both sides of the lower end of the rubber block 16. The limiting plates 161 are vertically slidably provided in the limiting holes on the corresponding sides. In this way, the limiting holes and the limiting plates 161 are used to block and prevent the rubber block 16 from running out of the damping groove 141, ensuring that the rubber block 16 is always in the damping groove 141. The damping structure can be used to buffer the bottom of the first filter element 5 and protect the filter plate when the first filter element 5 falls back to the initial position.

[0055] Of course, in other embodiments, the damping groove 141 can also be arranged at other positions of the upper end surface of the opening of the water collecting box 1, such as the front and rear side surfaces. In other embodiments, when meeting the actual use requirements, the damping block can also be a rigid plastic block or iron block.

[0056] Working process of this application:

[0057] When debris such as fallen leaves and branches fall on the first filter element 5, the dumping unit is activated, and the hydraulic rod 11 extends to lift the first filter element 5. Since the right end of the first filter element 5 is hinged to the water collecting tank 1, the first filter element 5 is flipped outward along the hinge shaft 17.

[0058] The cleaning unit is started, and the cleaning plate 8 moves to the right under the action of the multi-stage cylinder 7, and the cleaning plate 8 pushes the debris on the upper end of the first filter element 5 to move to the right until the debris slides from the right end of the first filter element 5 to the ground, completing the cleaning of the debris on the surface of the first filter element 5.

[0059] The multi-stage cylinder 7 drives the cleaning plate 8 to retract to the initial position, and the hydraulic rod 11 drives the first filter element 5 to fall back and cover the water collecting box 1 again. During the falling process, the buffer structure is used to buffer, so as to avoid the first filter element 5 from rigidly contacting the water collecting box 1 and improve the protection. In this way, the cleaning work of the filter structure is completed.

[0060] In summary, the agricultural water-saving irrigation equipment of the utility model can filter rainwater by arranging a first filter element 5 on the water collecting tank 1. The filtered rainwater can be collected in the inner cavity of the water collecting tank 1 for storage for later use. When debris such as fallen leaves falls on the first filter element 5 through the cleaning unit, the driving mechanism of the cleaning unit can be used to drive the cleaning plate 8 to slide on the first filter unit, and the cleaning plate 8 can be used to push and remove the debris to avoid the debris clogging the first filter hole 52 of the first filter plate, thereby ensuring the passability of rainwater and improving the rainwater recovery effect.
