Description

TECHNICAL FIELD

[0001] The present application relates to the field of drainage pipeline technology, in particular to a pick-up type underground water level control device. BACKGROUND

[0002] Rainwater, as a key element in the water cycle system, plays an important role in the process of building a sustainable urban water cycle system. City road sprinkling dust, green belt irrigation and other processes consume a lot of urban water resources. Under the national water management policy of water saving first, effectively and conveniently developing rainwater resource utilization is a great supplement to urban water resources.

[0003] The traditional rainwater management mode guides rainwater through pipes, water inlets, side stones and drainage ditches, and discharges rainwater into the sewer. Rainwater cannot be effectively utilized, resulting in waste of rainwater resources.

[0004] At present, there are water storage tanks on the market that directly collect rainwater, such as the Chinese utility model patent with application number 201920434103.7. Although this patent realizes the collection of rainwater, the storage capacity is limited and it is not connected to the urban drainage system, so it cannot adjust the storage capacity. When heavy rainfall occurs, urban waterlogging problems still occur. In addition, this patent cannot automatically output the collected rainwater according to the water demand, which is inconvenient for rainwater utilization.

[0005] And the existing water storage tank is mostly set above the ground. Because it is exposed to the outside and exposed to sunlight, it not only accelerates the aging of the material of the water storage tank, but also causes the temperature of the water storage tank and the rainwater stored inside to rise, which can accelerate the deterioration of the water quality and is not conducive to the maintenance of the rainwater quality.

[0006] Efficient supply of rainwater resources required for road sprinkling dust and green belt irrigation needs to meet the following conditions: first, rainwater storage is convenient. The storage device should be simple, rainwater should be easy to collect, and the occupied area should be as small as possible to adapt to the current situation of urban land shortage. At the same time, the storage device should be prefabricated and movable, and can be flexibly installed and adjusted according to the change of water demand points. Second, it has a decontamination function. Rainwater will carry branches, plastics and a large amount of dust after washing the ground, so it is necessary to remove the garbage and pollutants in the water body before it is used for road dust removal and green irrigation. Third, the storage water volume is adjustable. According to the water demand in the region, the storage water volume is reasonably set. Based on the above principles, a pick-up type underground water level control device is invented. SUMMARY

[0007] The present application provides a pick and pull type underground water level control device to solve the problems in the background art, which can collect rainwater, adjust water storage, discharge excess rainwater into underground drainage pipes, and monitor water demand.

[0008] To solve the above technical problems, the technical solutions adopted by the present application are as follows:

[0010] Further optimization of the technical solutions, the left and right sides of the storage box are provided with mounting cavities. The rainwater filtering and storage assembly includes a filter box fixedly installed inside the mounting cavities. One side of the filter box is provided with a plurality of water inlets. The inside of the water inlets is provided with an anti-reverse bracket to prevent garbage in the filter box from entering the storage box. The side of the filter box opposite to the water inlets is provided with a wire mesh. The inside wall of the filter box is provided with an underwater pump, the water outlet end of which protrudes above the ground, and the controlled end of the underwater pump is connected to the output end of the controller.

[0011] Further optimization of the technical solutions, the anti-reverse bracket includes a filter ring fixedly connected to the water inlets. The filter ring is provided with a plurality of plastic strips facing the inside of the filter box. The ends of the plastic strips opposite to the filter ring are close to each other.

[0012] Further optimization of the technical solutions, the side wall of the filter box is also provided with a convenient mounting mechanism. The convenient mounting mechanism includes a torsion bearing. The outer ring of the torsion bearing is fixedly connected to the side wall of the filter box. A rebound stand is fixedly installed in the inner ring of the torsion bearing, with a rebound torsion spring sleeved on the outside of the rebound stand. The end of the rebound stand is provided with a torsion circular plate. Two fixed pieces are provided on the side wall of the torsion circular plate opposite to the torsion bearing. Two compression frames for limiting the two fixed pieces are provided on the inside wall of the storage box.

[0013] The side of the torsion disc is provided with a pressing plate, and a plurality of elastic rods are arranged between the pressing plate and the filter box.

[0014] The liquid level jump mechanism further comprises an inner plate arranged in the machine box, and a conductive I-shaped frame is rotatably arranged on the side wall of the inner plate.

[0015] The side of the conductive I-shaped frame is provided with an elastic gear component for resetting the conductive I-shaped frame.

[0016] The elastic gear component further comprises a fixed pick rod fixed on the side wall of the inner plate, and the conductive I-shaped frame is provided with an extension piece.

[0017] The liquid level suspension pick component further comprises a lifting component arranged in the storage box and a pick support component arranged in the machine box and connected with the lifting component.

[0018] The lifting component further comprises two vertical guide rails fixed on the inner side wall of the storage box, and a lifting sliding block is slidably sleeved on the vertical guide rails.

[0019] The pick support component further comprises an inner circular rod fixedly connected with the inner side of the lifting plate, and the end of the inner circular rod is provided with a pick support arranged in the machine box.

[0020] The inner side wall of the storage box is provided with a plurality of drag blocks capable of adjusting the position, and the drag blocks are provided with a filter plate for filtering the entering rainwater.

[0021] The beneficial effects of the present application are as follows by adopting the technical scheme:

[0022] The present application can adjust the water storage capacity while collecting rainwater, effectively filter rainwater, drain excess rainwater into underground drainage pipes, and automatically monitor whether to perform green belt irrigation and other operations.

[0023] When the machine box and the storage box are used, they are buried underground. When it rains in the city, rainwater flows into the storage box from the water inlet at the top of the storage box. The rainwater is first filtered by the filter plate. The straw and plastic bag garbage in the rainwater will be retained on the filter plate. When the rainwater enters the storage box, the submersible pump will drive the water flow in the storage box to flow from the water inlet to the wire mesh. The rainwater is filtered for the second time. The plastic strip blocks the reverse flow of the strip-shaped impurities, achieving the effect of automatically filtering rainwater. The rainwater in the storage box is further removed after sedimentation and dust, and is stored for use on sunny days.

[0024] When the liquid level in the storage box rises, the plastic ball will be lifted upward by the buoyancy of the liquid level. When the pick-up support contacts and picks up the movable pick-up rod, the conductive I-shaped support will pop up and simultaneously contact two electrode plates. At this time, the water pump will be powered on and pump the rainwater in the storage box into the sewer to drain out. When the liquid level begins to drop, the lifting plate and the pick-up support fall down due to their own gravity. The pick-up support contacts and picks up the conductive I-shaped support to pop back. At this time, the water pump will be powered off and stop working, achieving the effect of automatically controlling the liquid level of the storage box.

[0025] When the storage box needs to be maintained, the cover plate at the top of the storage box is removed, and then the filter plate is pulled out by manually holding the two tension handles. Then the staff enters the inside of the storage box, holds the grip handle with four fingers, and presses the pressing plate with the thumb. The abutting steel ball under the pressing plate drives the slope block and the pressing plate to rotate together. The fixed pieces on both sides of the pressing plate will be separated from the pressing frame. At this time, the filter box can be taken out from the installation recess, achieving the effect of convenient disassembly and maintenance. BRIEF DESCRIPTION OF DRAWINGS

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0040] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0041] A pick-up type underground water level control device, in combination Figures 1 to 11 As shown, it comprises a storage box 3, a machine box 1, a water inlet assembly, a rainwater filtering and storing assembly, a ground water content detection assembly, a drainage mechanism, a liquid level jumping mechanism, a power supply and a controller.

[0042] The power supply is used to supply power to the whole device, and the power supply is arranged inside the machine box 1. The controller is used to control the operation of the whole device, and the controller can adopt a PLC programmable controller or a single-chip microcomputer with a control function, which is not limited here.

[0043] One side of the machine box 1 is provided with the storage box 3, and the storage box 3 and the machine box 1 are buried in the underground pit.

[0044] The top end of the storage box 3 is detachably provided with a cover plate, and the top end of the cover plate is provided with a water inlet assembly capable of entering rainwater and filtering rainwater. The water inlet assembly comprises a water inlet 301 and a water filter plate. The water inlet 301 is opened at the top end of the cover plate, and the water filter plate is arranged in the middle of the water inlet 301, and the water filter plate is flush with the ground.

[0045] The inside of the storage box 3 is provided with a rainwater filtering and storing assembly, which is used to filter and store rainwater, and prevent the internal garbage from entering the storage box 3, so as to ensure the cleanliness of the standby water in the storage box 3.

[0046] A surface moisture detection component protruding from the ground surface is installed at the top of the rainwater filtration and storage assembly. The output of the surface moisture detection component is connected to the input of the controller, and the controlled end of the rainwater filtration and storage assembly is connected to the output of the controller. The surface moisture detection component includes a moisture detector, which is installed at the top of the filter box 7, protruding from the ground surface, and its output is connected to the input of the controller.

[0047] To further enhance the water filtration effect, this invention also includes a filter plate 6 inside the storage box 3. Several adjustable drag blocks 304 are mounted on the top of the inner wall of the storage box 3. Each drag block 304 is fixedly connected to the inner wall of the storage box 3 by bolts, and there can be two drag blocks 304. The drag blocks 304 are equipped with the filter plate 6 for filtering incoming rainwater, and the filter plate 6 has several filter holes. During rainfall, rainwater first enters the storage box 3 through the inlet 301 for storage. The rainwater then passes through the filter plate 6 for filtration. The relative position of the filter plate 6 within the storage box 3 can be adjusted by the height of the drag blocks 304.

[0048] The storage box 3 has mounting cavities 303 on both the left and right sides.

[0049] The rainwater filtration and storage assembly includes a filter box 7 fixedly installed inside the mounting cavity 303. Several water inlets 701 are provided on one side of the filter box 7. An anti-reverse bracket is provided inside the water inlets 701 to prevent debris from the filter box 7 from entering the collection box 3. A wire mesh is provided on the side of the filter box 7 facing away from the water inlets 701. An underwater pump 707 is installed in the inner wall of the filter box 7. The outlet of the underwater pump 707 extends to the ground surface, and the controlled end of the underwater pump 707 is connected to the output end of a controller. After water is stored inside the collection box 3, there will still be small, rubber-like debris. The water flow from the water inlets 701 to the wire mesh filters the rubber-like debris onto the wire mesh. The debris is then emptied when the filter box 7 is removed.

[0050] The anti-reverse support includes a filter ring 705 fixedly connected to the inlet 701. Several plastic strips 706 are arranged on the filter ring 705 facing inwards towards the filter box 7, with the ends of the plastic strips 706 facing away from the filter ring 705 close together. The plastic strips 706 are made of plastic. After the filter box 7 stores waste, the waste inside the filter box 7 will float randomly; the plastic strips 706 prevent the waste from flowing out.

[0051] To enable quick installation and disassembly of the filter box 7, the present invention also provides a convenient installation mechanism on the side wall of the filter box 7.

[0052] The convenient installation mechanism comprises a torsion bearing 710, an outer ring of the torsion bearing 710 is fixedly connected with a side wall of the filter box 7, a rebound stand 711 is fixedly installed in an inner ring of the torsion bearing 710, a rebound torsion spring 712 is sleeved on an outer side of the rebound stand 711, and a torsion circular plate 713 is arranged at an end of the rebound stand 711. Two fixed pieces 709 are arranged on a side wall of the torsion circular plate 713, and two pressing frames 702 that limit the fixed pieces 709 are arranged on an inner side wall of the storage box 3.

[0053] The side of the torsion circular plate 713 is provided with a pressing assembly, the pressing assembly comprises a pressing plate 703, an elastic rod 708, a contact steel ball 715 and an inclined block 714. A plurality of elastic rods 708 are arranged between the pressing plate 703 and the filter box 7, and the elastic rods 708 are inserted into the side wall of the filter box 7. The end of the elastic rod 708 is further provided with a limiting head matched with the filter box 7.

[0054] Two contact steel balls 715 are arranged on the inner side wall of the pressing plate 703, and the side wall of the torsion circular plate 713 is provided with an inclined block 714 matched with the contact steel ball 715. When the pressing plate 703 is pressed, the pressing plate 703 is pressed to extrude the inclined block 714 through extruding the contact steel ball 715, so as to drive the torsion circular plate 713 and the fixed piece 709 to rotate, so as to drive the fixed piece 709 to be separated from the pressing frame 702.

[0055] The two sides of the pressing plate 703 are further provided with two grip handles 704, and the two fixed pieces 709 pass through the inside of one grip handle 704 respectively. The grip handle 704 plays a role of limiting the fixed piece 709 and facilitating hand holding.

[0056] The machine box 1 is provided with a drainage mechanism for pumping rainwater in the storage box 3, and a water outlet end of the drainage mechanism is connected with an underground drainage pipeline. The drainage mechanism comprises a water pump 2 arranged on a side of the storage box 3 opposite to the water pump 2. An input end of the water pump 2 is provided with a water suction pipe 201, the water suction pipe 201 extends to an inner side wall of the storage box 3 through a water suction pipe, an output end of the water pump 2 is provided with a drainage pipe 202, and the drainage pipe 202 is connected with the underground drainage pipeline. The water pump 2 on the side wall of the machine box 1 can pump the water in the storage box 3 into the sewer, so as to prevent the water in the storage box 3 from being too much and facilitate automatic adjustment of the water storage capacity.

[0057] The water in the storage box 3 can be used as standby water in a drought period. A nozzle is arranged on a green belt in the middle of a road, and the rainwater in the storage box 3 is pumped out for irrigation when it is dry.

[0058] The inner side of the machine box 1 is provided with a liquid level jump mechanism for controlling the opening and closing of the drainage mechanism according to the water level in the storage box 3. The liquid level jump mechanism comprises an embedded plate 5, a conductive I-shaped frame 505, an electrode plate 502, a spring position assembly, and a liquid level suspension pick-up assembly.

[0059] The embedded plate 5 is arranged inside the machine box 1 through four mounting flanges 501. A center bearing 504 is arranged on the side wall of the embedded plate 5. The conductive I-shaped frame 505 is arranged on one side of the center bearing 504. The outer ring of the center bearing 504 is fixedly connected with the side wall of the embedded plate 5. The conductive I-shaped frame 505 is rotatably arranged on the side wall of the embedded plate 5. A round rod is embedded in the inner ring of the center bearing 504 on one side of the conductive I-shaped frame 505. The material of the conductive I-shaped frame 505 is copper, which has good conductivity.

[0060] Two electrode plates 502 are diagonally arranged on the upper and lower sides of the embedded plate 5. Two traction guide wires 503 are drawn out of the two electrode plates 502. The two traction guide wires 503 are connected to the two ends of the power supply.

[0061] The conductive I-shaped frame 505 is provided with a spring position assembly on one side for resetting the conductive I-shaped frame 505. The spring position assembly is connected with a liquid level suspension pick-up assembly. The liquid level suspension pick-up assembly drives the conductive I-shaped frame 505 to rotate to control the opening and closing of the drainage mechanism according to the water level in the storage box 3. The conductive I-shaped frame 505 jumps back and forth between two positions through the spring position assembly. When the conductive I-shaped frame 505 contacts the electrode plate 502, a closed circuit is formed by the power supply. At this time, the water pump 2 starts to pump the water in the storage box 3 into the sewer pipe, achieving the effect of controlling the water storage capacity.

[0062] The spring position assembly comprises a fixed pick-up rod 506 fixed on the side wall of the embedded plate 5. An extension piece is arranged on one side of the conductive I-shaped frame 505. The extension piece is provided with a movable pick-up rod 507. The movable pick-up rod 507 extends away from the embedded plate 5. The movable pick-up rod 507 and the fixed pick-up rod 506 are located on both sides of the central axis of the conductive I-shaped frame 505 and are connected by a traction spring 508. The traction spring 508 pulls the movable pick-up rod 507 and the fixed pick-up rod 506. The conductive I-shaped frame 505 jumps back and forth between two angular positions. The conductive I-shaped frame 505 appears to be in two situations of being separated from the electrode plate 502.

[0063] The liquid level suspension pick-up assembly comprises a lifting assembly arranged inside the storage box 3 and a pick-up support assembly arranged inside the machine box 1 and connected with the lifting assembly.

[0064] The lifting assembly comprises two vertical guide rails 4 fixed on the inner side wall of the storage box 3, a lifting slider 401 sleeved on the vertical guide rails 4, a lifting plate 402 fixedly installed on the side wall of the lifting slider 401, an extension rod 403 arranged on one side of the lifting plate 402, and a plastic ball 404 arranged at the end of the extension rod 403 and suspended on the water surface. When it rains, the liquid level in the storage box 3 begins to rise, the plastic ball 404 is lifted by the buoyancy of the water, and when the liquid level in the storage box 3 drops, the plastic ball 404 and the lifting plate 402 fall down due to the weight, and the pick-up support assembly obtains power through the lifting plate 402, thereby facilitating automatic adjustment of the internal machine box 1.

[0065] The pick-up support assembly is arranged on the side of the lifting plate 402 opposite to the extension rod 403. The pick-up support assembly comprises an inner circular rod 406 fixedly connected to the inner side of the lifting plate 402, and a pick-up support 509 arranged in the internal machine box 1 and arranged at the end of the inner circular rod 406. The pick-up support 509 can drive the movable pick-up rod 507 to move by sliding up and down. A vertical sliding hole 302 is arranged on the side wall of the storage box 3 and matched with the inner circular rod 406, so that the inner circular rod 406 passes through the vertical sliding hole 302. A drag film 405 is arranged on the inner circular rod 406 of the machine box 1, and the drag film 405 and the machine box 1 form a sealed space.

[0066] When the pick-up support 509 slides up and down along with the lifting plate 402, the pick-up support 509 rises and touches the conductive I-shaped bracket 505, the conductive I-shaped bracket 505 jumps and contacts the electrode plate 502, and the pick-up support 509 slides down and touches the conductive I-shaped bracket 505 again, so that the conductive I-shaped bracket 505 jumps and separates from the electrode plate 502, thereby realizing the effect of automatic adjustment.

[0067] Further, the end of the extension rod 403 is provided with a bolt head, and the side wall of the lifting plate 402 is provided with a threaded hole matched with the bolt head. The plastic ball 404 at the end of the extension rod 403 is detachable. When it is necessary to replace the plastic ball 404, the extension rod 403 is manually rotated until the bolt head at the end of the extension rod 403 is separated from the lifting plate 402, and then a plastic ball 404 with greater buoyancy is replaced, thereby facilitating adjustment of the equipment.

[0068] The working process of the application is as follows:

[0069] The machine box and the storage box are buried underground. When it rains, the rainwater flows into the storage box from the water inlet at the top of the storage box and is stored in the storage box 3. The rainwater is preliminarily filtered by the filter plate 6, and the weeds and plastic bag garbage in the rainwater will be retained on the filter plate 6. When the rainwater enters the inside of the storage box, the submersible pump 707 starts to work to drive the water flow from the water inlet 701 to the wire mesh. This internal water flow can filter the strip-shaped garbage on the wire mesh, and the rainwater will be filtered for the second time and stored in the filter box 7.

[0070] In addition, the water level in the storage box 3 will also be adjusted according to the water level in the storage box 3. When the water level in the storage box 3 rises during the rain, the plastic ball 404 is lifted by the buoyancy of the water, the plastic ball 404 floats upward, the lifting assembly drives the picking support assembly to rise, and then drives the elastic gear assembly and the conductive I-beam 505 to rotate. The conductive I-beam 505 jumps back and forth between two positions through the elastic gear assembly, and the conductive I-beam 505 contacts the electrode plate 502 to form a closed circuit. At this time, the water pump 2 starts to pump the water in the storage box 3 into the sewer pipe, achieving the effect of controlling the water storage capacity. When the water pump 2 starts to pump the water in the storage box 3, the water pump 2 will pump the water in the filter box 7 into the storage box 3. In this process, because the filter box 7 is provided with an anti-reverse support, it can effectively prevent the garbage in the filter box 7 from entering the storage box.

[0071] When the water level in the storage box 3 drops, the plastic ball 404 and the lifting plate 402 fall down due to gravity, and then drive the picking support assembly to descend. The picking support assembly no longer drives the elastic gear assembly to rise, and the traction spring 508 will pull the movable picking rod 507 and the fixed picking rod 506 to drive the conductive I-beam 505 to reset. When the water level drops to a certain extent, the picking support 509 slides down and touches the conductive I-beam 505 again. The conductive I-beam 505 jumps and contacts the electrode plate 502, and the picking support 509 slides down and touches the conductive I-beam 505 again. The conductive I-beam 505 will jump away from the electrode plate 502, achieving the effect of automatic adjustment.

[0072] The conductive I-beam 505 will jump back and forth between two angle positions, and the conductive I-beam 505 will appear two situations of being separated from or connected to the electrode plate 502. The water in the storage box 3 is pumped out by the water pump 2 and discharged into the sewer, preventing the storage box 3 from having too much water, and facilitating automatic adjustment of the water storage capacity.

[0073] When the plastic ball 404 needs to be replaced, manually rotate the extension rod 403 until the bolt head at the end of the extension rod 403 is separated from the lifting plate 402, and then replace it with a plastic ball 404 with greater buoyancy, facilitating the adjustment of the equipment.

[0074] The present application is provided with a nozzle on the green belt in the middle of the road, the nozzle is communicated with the water outlet of the water supply pump through the water supply pipeline, the water supply pump can be arranged in the storage box 3, and the controlled end of the water supply pump is connected to the output end of the controller. When the water detection instrument detects that the ground water is too low, the controller controls the water supply pump to pump the water in the storage box to the nozzle to be sprayed out, so that the automatic reuse of rainwater is realized.

[0075] And in the dry period, the present application can also open the cover plate and the filter plate 6, and draw the rainwater in the storage box 3 for irrigation, so that the water in the storage box 3 is utilized.

[0076] When the garbage in the filter box 7 is cleaned and maintained, the worker enters the inside of the storage box 3, then four fingers hold the grip handle 704, the thumb starts to press the pressing plate 703, the abutting steel ball 715 under the pressing plate 703 drives the inclined block 714 and the pressing plate 703 to rotate together, and the fixed sheet 709 on both sides of the pressing plate 703 is separated from the pressing frame 702, at this time, the filter box 7 can be taken out from the installation recess 303, and the garbage is poured out when the filter box 7 is disassembled, so that the convenient disassembly and maintenance effect are realized.

[0077] The above only describes the preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
