[0002] A rainwater storage tank is a rainwater collection facility, and its main function is to collect and temporarily store the peak flow of rainwater runoff. The rain grate is usually arranged at the water inlet of the rainwater storage tank to remove impurities, fallen leaves, etc. in the water and maintain the cleanliness of the rainwater, so that the rainwater entering the rainwater storage tank can be used for activities such as watering and washing later.

[0003] During rain, impurities, fallen leaves, etc. will accumulate on the surface of the rain grate, which will cause a certain degree of blockage of the rain grate. This will cause rainwater to be unable to be discharged into the rainwater storage tank in time when it rains heavily, and the rain grate cannot completely intercept impurities, fallen leaves, etc., which will cause impurities such as fallen leaves to enter the rainwater storage tank and accumulate, and it is not easy for subsequent staff to clean the impurities.

[0011] As a further solution of the present invention, the water level measuring mechanism includes a floating plate, the floating plate is slidably connected to the inner wall of the water storage pool in the vertical direction, a first traction rope is fixedly connected to the bottom surface of the floating plate, and one end of the first traction rope away from the floating plate passes through the side walls of the water storage pool and the collection pool and is fixedly connected to the wedge-shaped limiting block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the arrangement of the first grating body, the second grating body, the reservoir, the water inlet, the filter plate and the collection pool, the second grating body is in a horizontal state, which can intercept large sundries such as branches. The first grating body and the filter plate are arranged vertically. They can not only intercept small impurities such as sediment and fallen leaves, but also make the impurities automatically fall into the collection pool under the action of gravity for collection. This can prevent the first grating body and the filter plate from being blocked, ensure that impurities do not enter the reservoir, and better guarantee the cleanliness of the rainwater in the reservoir. After the rain stops, the staff can open the second grating body downward. The second grating body will combine with the first grating body to form a complete baffle, and at this time the water passing holes are completely closed, which is convenient for the staff to clean the impurities at the bottom of the collection pool. At the same time, the impurities will not adhere to the filter plate when moving upward, which can better prevent the filter plate and the rain grate from being blocked.

[0017] 2. Through the arrangement of the slide plate, the impurities intercepted by the first grating body and the filter plate will fall onto the slide plate under the action of gravity. As the weight of the impurities on the slide plate increases, the slide plate will move downward and compress the first spring. When cleaning the accumulated impurities in the collection pool, as the upper impurities on the slide plate are cleaned, the slide plate will move upward under the action of the first spring. The slide plate can drive the lower impurities to move upward for a certain distance, which is convenient for the staff to clean the impurities.

[0018] 3. Through the arrangement of the wedge-shaped limit block and the water level measuring mechanism, when the water level in the reservoir reaches a certain height, the water level measuring mechanism can drive the wedge-shaped limit block to cancel the limit on the second grating body, and then the second grating body can rotate downward under the action of gravity; until the second grating body is completely closed with the first grating body, at this time the rainwater no longer enters the reservoir and can directly flow downstream from the top surface of the reservoir; after the first grating body and the second grating body are closed, the first grating body, the second grating body and the filter plate can stop the filtering work, which can greatly reduce the working pressure of the first grating body, the second grating body and the filter plate; after the second grating body is opened, the staff can clean the impurities in the collection pool at any time; and only when the water level in the reservoir reaches a certain height, the second grating body will automatically open, which can ensure that the second grating body better intercepts large sundries.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0029] Please refer to Figures 1 - 7 , the present invention provides a technical solution: a rainwater grate, including a first grate body 1 and a second grate body 2, the first grate body 1 and the second grate body 2 are connected by a hinge shaft 3; water passing holes 4 are provided on both the first grate body 1 and the second grate body 2; the water passing holes 4 on the first grate body 1 and the second grate body 2 are arranged in a staggered manner; the water passing holes 4 are completely closed when the first grate body 1 and the second grate body 2 are closed.

[0030] A rainwater storage tank further includes a reservoir 5, a water inlet 6 is provided on the right side wall of the reservoir 5, the first grate body 1 is installed in the water inlet 6, a filter plate 7 is fixedly installed on the water inlet 6, and the filter plate 7 is located inside the first grate body 1; a collection pool 8 is arranged on the side of the reservoir 5, and the second grate body 2 is flush with the top surfaces of the reservoir 5 and the collection pool 8.

[0031] During operation, as Figures 1 - 3As shown in the figure, when it is raining, rainwater enters the collection pool 8 through the water passing holes on the second grate body 2. After the rainwater in the collection pool overflows the water inlet 6, the rainwater will enter the reservoir 5 through the water passing holes 4 and the water inlet 6 on the first grate body 1. When the rainwater passes through the water inlet 6, the filter plate 7 will filter the rainwater. The first grate body 1 can intercept large impurities such as fallen leaves, and the filter plate 7 can intercept small particulate matters such as sediment carried in the rainwater. Then, impurities such as fallen leaves and sediment will fall downward under the action of their own gravity to accumulate at the bottom of the collection pool, thereby avoiding blockage of the first grate body 1 and the filter plate 7 and enabling rainwater to better drain into the reservoir 5. After the rain stops, the staff can open the second grate body 2 downward. The second grate body 2 will combine with the first grate body 1 to form a complete baffle. At this time, the water passing holes 4 are completely closed, which is convenient for the staff to clean the impurities at the bottom of the collection pool 8. At the same time, the impurities will not adhere to the filter plate 7 when moving upward, which can better prevent blockage of the filter plate and the rainwater grate.

[0032] As a further solution of the present invention, a sliding plate 9 is slidably installed on the collection pool 8 in the vertical direction. The bottom of the sliding plate 9 is fixedly connected with a first spring 10, and one end of the first spring 10 away from the sliding plate 9 is fixed at the bottom of the collection pool 8.

[0033] During operation, as Figure 3 shown, through the setting of the sliding plate 9, the impurities intercepted by the first grate body 1 and the filter plate 7 will fall onto the sliding plate 9 under the action of gravity. As the weight of the impurities on the sliding plate 9 increases, the sliding plate 9 will move downward and compress the first spring 10. When cleaning the impurities accumulated in the collection pool 8, as the upper-layer impurities on the sliding plate 9 are cleaned, the sliding plate 9 will move upward under the action of the first spring 10, and the sliding plate 9 can drive the lower-layer impurities to move upward for a certain distance, which is convenient for the staff to clean the impurities.

[0034] As a further solution of the present invention, a wedge-shaped limit block 11 is slidably installed on the collection pool 8; a second spring 12 for its reset is fixedly connected to the wedge-shaped limit block 11; the wedge-shaped limit block 11 is located below the second grate body 2 and is used to limit the second grate body 2; a water level measuring mechanism is arranged in the reservoir 5. After the water level measuring mechanism detects that the water level in the reservoir 5 reaches a specified height, it will drive the wedge-shaped limit block 11 to cancel the limit on the second grate body 2, and the second grate body 2 will rotate to a closed state with the first grate body 1; the water level measuring mechanism includes a floating plate 13, the floating plate 13 is slidably connected to the inner wall of the reservoir 5 in the vertical direction, and a first traction rope 14 is fixedly connected to the bottom surface of the floating plate 13. One end of the first traction rope 14 away from the floating plate 13 passes through the side walls of the reservoir 5 and the collection pool 8 and is fixedly connected to the wedge-shaped limit block 11.

[0035] During operation, as Figures 3 - 5As shown, when rainwater enters the water storage tank 5, the liquid level will gradually rise. When the liquid level rises to contact the floating plate 13, the liquid level will continue to rise and drive the floating plate 13 to move upward. The floating plate 13 will drive the wedge-shaped limit block 11 to move away from the second grate body 2 through the first traction rope 14 until the wedge-shaped limit block 11 cancels the limit on the second grate body 2, and then the second grate body 2 will rotate downward under the action of gravity; until the second grate body 2 and the first grate body 1 are completely closed, at this time, rainwater no longer enters the water storage tank, and rainwater can directly Then it flows downstream from the top surface of the water reservoir; after the first grate 1 and the second grate 2 are closed, the first grate 1, the second grate 2 and the filter plate 7 no longer need to perform filtering work, which can greatly reduce the working pressure of the first grate 1, the second grate 2 and the filter plate 7; after the second grate 2 is opened, the staff can clean the impurities in the collection pool 8 at any time; and only when the water level in the water reservoir 5 reaches a certain height, the second grate 2 will automatically open, which can ensure that the second grate 2 can better intercept large debris.

[0036] As a further solution of the present invention, a hemispherical block 15 is fixedly connected to the bottom surface of the floating plate 13, and the hemispherical block 15 is in a hollow state.

[0037] When working, Figure 5 As shown, by disposing the hemispherical block 15 , the buoyancy of the floating plate 13 can be better increased.

[0038] As a further solution of the present invention, a mounting groove 16 is provided on the top of the collection tank 8, a turbine shell 17 is provided in the mounting groove 16, a turbine 18 is provided in the turbine shell 17, and a water inlet 19 and a water outlet 20 are provided on the turbine shell 17; a second traction rope 21 is fixedly connected to the turbine shell 17, and the second traction rope 21 passes through the collection tank 8 at one end away from the turbine shell 17 and is fixedly connected to the second grate body 2; a first sprocket 22 is fixedly connected to the rotating shaft of the turbine 18; the first A second sprocket 23 and a tensioning wheel 24 are arranged below the sprocket 22, and the first sprocket 22, the second sprocket 23 and the tensioning wheel 24 are connected through a chain 25; a first slider 26 is mounted on the rotating shaft of the tensioning wheel 24, and the first slider 26 is elastically slidably connected to the collecting tank 8; the second sprocket 23 is rotatably connected to the collecting tank 8, and a gear 27 is fixedly connected to the rotating shaft of the second sprocket 23, and the gear 27 is meshed with a rack rod 28, and the rack rod 28 is fixedly installed at the bottom of the slide plate 9.

[0039] When working, Figure 6 and Figure 7As shown in the figure, when the water level in the reservoir 5 reaches a certain height and the second grate body 2 rotates downward, the second grate body 2 will drive the turbine housing 17 to move upward through the second traction rope 21. The turbine housing 17 will drive the turbine 18 and the first sprocket 22 to move upward synchronously until the water inlet hole 19 and the water outlet hole 20 move above the top surface of the collection pool. At this time, the rainwater grate is closed. Then, when the rainwater flows through the top of the reservoir and the collection pool, the rainwater will flow into the turbine housing 17 from the water inlet hole 19 and then flow out from the water outlet hole 20. The flow of the rainwater will drive the turbine 18 to rotate. The turbine 18 will drive the first sprocket 22 to rotate. The first sprocket 22 will drive the tension pulley 24 and the second sprocket 23 to rotate synchronously through the chain 25. The second sprocket 23 will drive the gear 27 to rotate synchronously. The gear 27 will drive the rack bar 28 to move upward. When the rack bar 28 moves upward to a critical state where its meshing with the gear 27 is at a critical state, the rotation of the gear 27 will drive the rack bar 28 to vibrate up and down. The upward movement of the rack bar 28 can drive the slide plate 9 to move downward synchronously, making the impurities closer to the water flow. The vibration of the rack bar 28 can drive the slide plate 9 to vibrate synchronously. Then, when the rainwater flows through, some impurities can be washed onto the ground, greatly reducing the amount of impurities on the slide plate 9 and facilitating the subsequent cleaning of impurities by the staff. After the rain stops, after the staff cleans the impurities in the collection pool 8, the staff can press down the turbine housing 17 to make the turbine housing 17 retract into the installation groove 16. When the turbine 18 does not need to work, the turbine housing 17 can retract into the installation groove 16, greatly improving the service life of the turbine housing 17. The downward movement of the turbine housing 17 can drive the second grate body 2 to rotate upward back to the horizontal position through the second traction rope 21, and then the second grate body 2 can be limited by the wedge-shaped limiting block 11 again.

[0040] As a further solution of the present invention, a card slot 29 is provided on the side wall of the turbine housing 17. A block 30 capable of being clamped with it is provided on the side of the card slot 29. The block 30 is elastically slidably connected to the collection pool 8. A third traction rope 31 is fixedly connected to the block 30. The top end of the third traction rope 31 is fixedly connected to a second slider 32. The second slider 32 is slidably connected to the collection pool 8 in the vertical direction.

[0041] During operation, as Figure 6 shown in the figure, when the turbine housing 17 moves upward to expose the water inlet hole 19 and the water outlet hole 20, the card slot 29 will move to the immediate left of the block 30, and then the block 30 will be inserted into the card slot 29 under the action of the spring to limit the turbine housing 17. It can ensure that the turbine housing 17 will not move downward due to accidental touch. After the staff cleans the impurities in the collection pool, the second slider 32 can be hooked up by a special tool. The second slider 32 will drive the block 30 to move away from the turbine housing 17 through the third traction rope 31, and then the staff can press down the turbine housing 17 to make the turbine housing 17 retract into the installation groove 16.
