Description

Technical Field

[0001] The present invention relates to the technical field of sewers, in particular to a sunken rainwater collection green belt. Background Art

[0002] In urban road construction, green belts will be built between two roads. The function of green belts is to separate traffic and beautify roads. Drainage channels will be set up on both sides of the green belts, and reservoirs will be set up under the green belts to supply water to the green belts or directly discharge it into the rainwater purification system. In order to improve the utilization rate of rainwater, sunken rainwater collection green belts are needed.

[0003] Although the existing sunken rainwater collection green belt can collect and filter rainwater, when the rainfall is small, the rainwater cannot meet the water requirements of the green plants in the green belt. The existing sunken rainwater collection green belt will still discharge the rainwater into the reservoir, and then replenish the green belt through the water replenishment device, thereby wasting a lot of energy and requiring staff to monitor the green belt for a long time. It is more cumbersome to use. Therefore, we propose a sunken rainwater collection green belt. Summary of the Invention

When rainwater needs to be collected, the rainwater flows into the interior of the collection mechanism through the manhole cover. The rainwater is intermittently discharged through the collection mechanism. Subsequently, the rainwater is separated from debris and sewage by the separation mechanism, so that the separated rainwater is slowly and repeatedly discharged into the soil of the green belt to irrigate the green belt.

[0010] The diverter device includes a diverter plate fixed at the bottom of the outer box, two springs are provided on the top of the diverter plate to drive the collecting mechanism to move up and down, and a guide mechanism is also provided on the diverter plate to quickly transport rainwater to the inside of the sewer pipe, the middle part of the diverter plate is recessed downward to form a drainage slope, and the middle part of the drainage slope is provided with a drainage outlet adapted to the irrigation pipe, the bottom of the outer box is fixed to the diverter plate, the bottom of the spring is fixed to the diverter plate, and the top of the spring is fixed to the top of the bottom plate, and the water storage barrel can be pushed up and down by the elastic force of the spring, and rainwater flows into the diverter plate through the separation mechanism and is discharged through the guide mechanism. When the flow rate of rainwater is small, the rainwater is transported to the inside of the irrigation pipe through the drainage outlet through the separation mechanism and the guide mechanism, so that the rainwater flows into the green belt through the irrigation pipe. When the flow rate of rainwater is large, the separation mechanism fills the drainage outlet, so that the rainwater is quickly discharged into the inside of the sewer pipe through the guide mechanism.

When the rainfall is small, the weight of the rainwater accumulated in the water barrel and the spring cooperate to drive the water barrel to move back and forth, so that the rainwater inside the water barrel is intermittently discharged into the diversion mechanism, and the rainwater is transported to the inside of the irrigation pipe through the diversion mechanism and the diversion mechanism to irrigate the green belt. When the rainfall is large, the rainwater accumulated in the water barrel is large and heavy, and the water barrel drives the separation mechanism to move downward, so that the bottom of the separation mechanism is inserted into the drain port, blocking the drain port, and causing the rainwater to flow into the interior of the outer box. The rainwater inside the outer box flows into the interior of the sewer pipe through the diversion mechanism, thereby quickly discharging the rainwater inside the water barrel.

When the rainfall is small, the bottom plate moves downward, causing the bottom plate to drive the sealing block to move downward, and the sealing block does not contact the drainage slope and the drainage port, so that the rainwater flows into the interior of the irrigation pipe through the drainage port, thereby irrigating the green belt. When the rainfall is large, the bottom plate moves downward quickly, causing the bottom plate to drive the sealing block to move downward, so that the inclined surface of the sealing block contacts the drainage slope, and at the same time, the water blocking block is inserted into the interior of the drainage port to seal the drainage port, so that the rainwater is transported to the interior of the sewer pipe through the diversion mechanism.

[0040] The water storage device 4 includes an outer box 401 and a mounting plate 412. A fixing plate 413 is fixed to the top of the outer wall of the outer box 401. Bolts are provided between the mounting plate 412 and the fixing plate 413. A collection mechanism for collecting and intermittently discharging rainwater is provided inside the outer box 401. A separation mechanism for filtering rainwater is also provided below the collection mechanism. The bottom of the outer box 401 is connected to the diversion mechanism, and the mounting plate 412 is fixed to the ground by bolts. The mounting plate 412 is fixed to the top of the fixing plate 413 by bolts. When rainwater needs to be collected, the rainwater flows into the interior of the collecting mechanism through the manhole cover 1, and the rainwater is intermittently discharged through the collecting mechanism. Subsequently, the rainwater separates debris and sewage through the separation mechanism, so that the separated rainwater is slowly and repeatedly discharged into the soil of the green belt to irrigate the green belt.

[0041] The diversion device 5 includes a diversion plate 501 fixed below the outer box 401. Two springs 502 are set on the top of the diversion plate 501 to drive the collection mechanism to move up and down. The diversion plate 501 is also provided with a guide mechanism for quickly transporting rainwater to the inside of the sewer pipe 2. The middle part of the diversion plate 501 is concave downward to form a drainage slope. The middle part of the drainage slope is provided with a drainage port adapted to the irrigation pipe 3. The bottom of the outer box 401 is fixed to the diversion plate 501, the bottom of the spring 502 is fixed to the diversion plate 501, and the top of the spring 502 is fixed to the diversion plate 501. It is fixed to the top of the bottom plate 403, and the elastic force of the spring 502 can push the water storage barrel 404 up and down. The rainwater flows into the diverter plate 501 through the separation mechanism, and is discharged through the diversion mechanism. When the flow of rainwater is small, the rainwater is transported to the inside of the irrigation pipe 3 through the drainage port through the separation mechanism and the diversion mechanism, so that the rainwater flows into the green belt through the irrigation pipe 3. When the flow of rainwater is large, the separation mechanism fills the drainage port, so that the rainwater is quickly discharged to the inside of the sewer pipe 2 through the diversion mechanism.

[0042] The collecting mechanism includes a water storage barrel 404 arranged inside the outer box 401 and a connecting rod 406 fixed on the manhole cover 1, a blocking block 407 in the shape of an inverted cone is fixed to the bottom of the connecting rod 406, a bottom plate 403 is fixed to the bottom of the water storage barrel 404, a through hole adapted to the blocking block 407 is opened on the bottom plate 403, the blocking block 407 is inserted in the through hole, the bottom of the bottom plate 403 is fixed to the top of the spring 502, the top of the blocking block 407 is in contact with the top of the through hole, the through hole is sealed by the blocking block 407, so that the rainwater inside the water storage barrel 404 is temporarily stored, when the rainwater enters the water storage barrel 404 through the manhole cover 1, the rainwater is stored inside the water storage barrel 404, and the weight of the accumulated rainwater drives the water storage barrel 404 to move downward, so that the water storage barrel 404 drives the bottom plate 403 to move downward, so that the bottom plate 403 Separated from the blocking block 407, the rainwater inside the water barrel 404 flows into the separation mechanism through the through hole. When the rainfall is small, the weight of the rainwater accumulated in the water barrel 404 and the cooperation of the spring 502 drive the water barrel 404 to move up and down reciprocatingly, so that the rainwater inside the water barrel 404 is intermittently discharged into the diversion mechanism, and the rainwater is transported to the inside of the irrigation pipe 3 through the diversion mechanism and the diversion mechanism to irrigate the green belt. When the rainfall is large, the rainwater accumulated in the water barrel 404 is large and the weight is large. The water barrel 404 drives the separation mechanism to move downward, so that the bottom of the separation mechanism is inserted into the drain outlet, blocking the drain outlet, and causing the rainwater to flow into the interior of the outer box 401. The rainwater inside the outer box 401 flows into the interior of the sewer pipe 2 through the diversion mechanism, thereby quickly discharging the rainwater inside the water barrel 404.

[0043] The separation mechanism includes a threaded ring 411 fixed to the bottom of the bottom plate 403, the bottom of the threaded ring 411 is screwed with a filter cartridge 402 for filtering rainwater, a sealing block 409 is fixed to the bottom of the filter cartridge 402, and an inclined surface adapted to the drainage slope is provided below the sealing block 409, and a water blocking block adapted to the drainage outlet is fixed to the bottom of the inclined surface, and a plurality of filter holes are provided on the filter cartridge 402, and a threaded groove adapted to the threaded ring 411 is provided on the inner wall of the filter cartridge 402. Through the cooperation between the threaded groove of the filter cartridge 402 and the threaded ring 411, the filter cartridge 402 can be quickly installed on the threaded ring 411, and it is also convenient for people to clean the filter cartridge 402. The cylinder 402 filters rainwater to prevent debris from entering the irrigation pipe 3 and blocking the irrigation pipe 3. When the rainfall is small, the bottom plate 403 moves downward, causing the bottom plate 403 to drive the sealing block 409 to move downward, and the sealing block 409 does not contact the drainage slope and the drainage outlet, so that rainwater flows into the interior of the irrigation pipe 3 through the drainage outlet, thereby irrigating the green belt. When the rainfall is large, the bottom plate 403 moves downward quickly, causing the bottom plate 403 to drive the sealing block 409 to move downward, so that the inclined surface of the sealing block 409 contacts the drainage slope, and at the same time, the water blocking block is inserted into the interior of the drainage outlet to seal the drainage outlet, so that the rainwater is transported to the interior of the sewer pipe 2 through the diversion mechanism.

[0044] The diversion mechanism includes an overflow plate 503 fixed on the top of the diverter plate 501 and a plurality of drain pipes 504 fixed between the diverter plate 501 and the downpipe 2, and the diverter plate 501 is provided with a plurality of drain ports adapted to the drain pipes 504. One end of the plurality of drain pipes 504 away from the diverter plate 501 passes through the downpipe 2 and extends to the inside of the downpipe 2. The rainwater on the diverter plate 501 and the outer box 401 flows into the inside of the drain pipe 504 through the drain port, and the diverter plate 501 and the outer box 401 can be quickly drained through the drain pipe 504. The water inside the box 401 is discharged to prevent rainwater from accumulating inside the diverter plate 501 and the outer box 401. When the inclined surface of the sealing block 409 contacts the drainage slope, the sealing block 409 is inserted into the inside of the overflow plate 503. Through the cooperation between the overflow plate 503 and the sealing block 409, the top of the drain outlet is sealed, so that rainwater flows through the drain pipe 504 through the drain outlet and enters the interior of the sewer pipe 2, so that the rainwater inside the water storage barrel 404 can be discharged quickly, and excessive watering of the green belt when the rainfall is heavy can be avoided.

[0045] A connecting pipe 505 is fixed to the bottom of the diverter plate 501. The connecting pipe 505 is arranged in an inverted Y shape. The end of the connecting pipe 505 away from the diverter plate 501 is connected to the irrigation pipe 3. The rainwater is diverted through the connecting pipe 505 so that the rainwater can irrigate the green belts on both sides of the sewer pipe 2 at the same time, thereby increasing the irrigation area.

[0046] By adopting the above technical solutions:

[0047] During use, when the rainfall is small, when the bottom plate 403 moves downward, the bottom plate 403 drives the sealing block 409 to move downward, and the sealing block 409 does not contact the drainage slope and the drainage outlet, so that rainwater flows into the interior of the irrigation pipe 3 through the drainage outlet, thereby directly irrigating the green belt, without the need to discharge the rainwater into the water reservoir and then irrigate it through the water replenishment device, thereby eliminating the need for staff to monitor the green belt for a long time, saving resources, and being simple, convenient and fast to operate;

[0048] When the rainfall is heavy, the bottom plate 403 moves downward quickly, causing the bottom plate 403 to drive the sealing block 409 to move downward, so that the inclined surface of the sealing block 409 contacts the drainage slope, and the sealing block 409 is inserted into the interior of the overflow plate 503. Through the cooperation of the overflow plate 503 and the sealing block 409, the top of the drain outlet is sealed, so that rainwater flows through the drain pipe 504 through the downpipe 504 and then enters the interior of the downpipe 2, so that the rainwater inside the water storage barrel 404 can be discharged quickly, and the green belt can be prevented from being over-irrigated when the rainfall is heavy. At the same time, the water blocking block is inserted into the interior of the drain outlet, sealing the drain outlet, so that rainwater flows into the interior of the outer box 401, and the rainwater inside the outer box 401 flows through the downpipe 504 through the downpipe and then enters the interior of the downpipe 2, so that the rainwater inside the water storage barrel 404 can be discharged quickly, and the green belt can be prevented from being over-irrigated when the rainfall is heavy.

[0049] Secondly, reference Figure 3 、 Figure 4 and Figure 5 As shown, two limiting posts 410 are symmetrically fixed to the bottom of the bottom plate 403, and two sliding rods 408 are symmetrically fixed to the outer wall of the water storage barrel 404. The inner wall of the outer box 401 is provided with a sliding groove for facilitating the sliding of the sliding rods 408. The limiting posts 410 are inserted into the inside of the two springs 502. The limiting posts 410 prevent the springs 502 from bending when compressed or extended, causing the device to be unable to be used normally. The limiting posts 410 are driven downward by the bottom plate 403 to make the bottom of the limiting posts 410 contact with the top of the diverter plate 501, thereby adjusting the bottom plate 403. The limit prevents the sealing block 409 from colliding with the connecting pipe 505 when the bottom plate 403 drives the sealing block 409 to move downward, thereby damaging the sealing block 409 or the connecting pipe 505 and affecting the service life of the sealing block 409 or the connecting pipe 505. When the water storage bucket 404 moves up and down, the water storage bucket 404 drives the sliding rod 408 to move up and down, so that the sliding rod 408 moves up and down along the inner wall of the sliding groove. The sliding rod 408 is limited by the sliding groove, and the sliding rod 408 limits the water storage bucket 404, thereby preventing the water storage bucket 404 from rotating when moving up and down and damaging the spring 502.

[0050] By adopting the above technical solutions:

[0051] During use, when the water storage bucket 404 moves up and down, the water storage bucket 404 drives the slide rod 408 to move up and down, so that the slide rod 408 moves up and down along the inner wall of the slide groove, and the slide rod 408 is limited by the slide groove, and the slide rod 408 limits the water storage bucket 404, thereby preventing the water storage bucket 404 from rotating when moving up and down and damaging the spring 502.

[0052] Again, reference Figure 4 and Figure 7 As shown, a water retaining ring 405 is fixed to the bottom of the manhole cover 1, and the bottom of the water retaining ring 405 is inserted into the inside of the water storage barrel 404. The water retaining ring 405 blocks the rainwater flowing into the water storage barrel 404 from the manhole cover 1, preventing rainwater with debris from flowing into the inside of the outer box 401, blocking the drain outlet and the sewer outlet, and affecting the normal use of the device.

[0053] By adopting the above technical solutions:

[0054] When in use, the water retaining ring 405 blocks rainwater flowing into the water storage barrel 404 from the manhole cover 1, preventing rainwater with debris from flowing into the interior of the outer box 401 and blocking the drain outlet and the sewer port, thereby affecting the normal use of the device.

[0055] Finally, reference Figure 1 and Figure 11 As shown, two baffles 7 are provided on the mounting plate 412, two clamping blocks 6 are fixed to the outside of the manhole cover 1, and two annular grooves 8 are provided at the bottom of the mounting plate 412 for facilitating the movement of the clamping blocks 6. A torsion spring is provided between the baffles 7 and the mounting plate 412. After aligning the two clamping blocks 6 with the baffles 7, push the clamping blocks 6 downward to allow the manhole cover 1 to enter the interior of the mounting plate 412, rotate the manhole cover 1, and allow the manhole cover 1 to drive the clamping blocks 6 to move along the inside of the annular grooves 8. The clamping blocks 6 are limited by the annular grooves 8, so that the manhole cover 1 can be installed inside the mounting plate 412 quickly and conveniently.

[0056] By adopting the above technical solutions:

[0057] When in use, align the two blocks 6 with the baffle 7, push the block 6 downward to allow the manhole cover 1 to enter the interior of the mounting plate 412, rotate the manhole cover 1, and allow the manhole cover 1 to drive the block 6 to move along the inside of the annular groove 8. The block 6 is limited by the annular groove 8, so that the manhole cover 1 can be installed inside the mounting plate 412, which is convenient and quick.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
