Description

Technical Field

[0001] The present invention relates to the technical field related to urban drainage systems, and in particular to an underground drainage treatment device for an urban park and a method for using the device. Background Art

[0002] With the development of society, people are no longer just pursuing the practicality of a product, but have a higher pursuit of the appearance of a product. Parks are one of the main contents of urban construction and an important part of the urban landscape. They meet the leisure needs of urban residents and can provide places for rest, sightseeing, exercise and various collective cultural activities. The drainage systems in parks are relatively hidden, and linear drainage ditches are often used, but the filter holes are easily blocked by dead branches and leaves.

[0003] Chinese patent announcement number CN112627316A discloses a municipal drainage manhole cover, which can effectively improve the drainage efficiency of the drainage manhole cover by setting a main frame, a receiving slot, a lifting slot, a limiting slide slot, a connecting slot, a filter box, a filter bin, a filter hole, a No. 1 drainage cover, a No. 2 drainage cover, a drainage hole, a warning tube, a limiting slider, a No. 1 casing, a No. 2 casing, a rotating connecting rod, a connecting column, a connecting hole and a floating block. During daily drainage, rainwater enters the filter bin through the drainage hole for filtration and drainage. In heavy rain weather, the amount of rainwater flowing in is large. When the filtration speed of the filter box is low, rainwater will accumulate in the filter bin and drive the float block to rise. The float block can push one end of the No. 1 drain cover and the No. 2 drain cover upward through the connecting column, rotating connecting rod, No. 1 sleeve and No. 2 sleeve. The other ends of the No. 1 drain cover and the No. 2 drain cover will approach each other along the inner wall track of the limiting slide. The No. 1 drain cover and the No. 2 drain cover are in a folded and raised state, and the accumulated water on the road will flow directly into the drainage pipe along the gap, thereby effectively improving the drainage speed of the accumulated water and avoiding the damage of the accumulated water to public facilities caused by long-term accumulation of water on the ground.

[0004] In summary, it can be seen that traditional municipal drainage facilities are difficult to take into account the dual functions of filtration effect and drainage efficiency. This causes the drainage filter holes to either be blocked by dead branches and leaves, affecting drainage efficiency, or be discharged into the sewer system together with the dead branches and leaves, which can easily cause pipe blockage. Summary of the Invention

[0005] In response to the defects in the existing technology, the present invention provides an underground drainage treatment device for urban parks and a method for using the same, which solves the problem that traditional municipal drainage facilities are difficult to balance the dual functions of filtration effect and drainage efficiency. This causes the drainage filter holes to either be blocked by dead branches and leaves, affecting the drainage efficiency, or be discharged into the sewer system together with the dead branches and leaves, easily causing pipe blockage.

[0009] Furthermore, the pressure relief assembly also includes a hinged seat fixed to the bottom wall of the water storage tank, an inclined rod is hinged on the hinged seat, a second float is fixed in the middle of the inclined rod, and a pull rope is fixedly connected between the second float and the right-angle plate.

[0010] Furthermore, the reciprocating assembly includes two guide rails fixed to the inner wall of one side of the water storage tank, a rectangular frame is slidably connected between the two guide rails, a plurality of limit plates are fixedly connected to one side of the rectangular frame, a plurality of vertical holes are opened on the limit plates, and a shift rod is slidably embedded between the upper and lower vertical holes, and a limit block is fixedly sleeved on the outside of the shift rod and below the limit plate.

[0011] Furthermore, the reciprocating assembly also includes two racks fixed on the upper and lower inner walls of the rectangular frame respectively, a fan-shaped gear is arranged between the two racks, and the fan-shaped gear is engaged with the two racks in turn, and the middle fixed sleeve of the fan-shaped gear is provided with an upper rotating shaft, and the upper rotating shaft is arranged to pass through the water storage tank.

[0012] Furthermore, the transmission assembly includes a lower rotating shaft rotatably embedded in the inner wall of one side of the pump body, the outer side of the lower rotating shaft and the part located inside the pump body are fixedly connected to multiple fan blades, one end of the lower rotating shaft and one end of the upper rotating shaft are fixedly connected to a wheel, and a belt is connected for transmission between the two wheels.

[0013] Furthermore, a circular cavity is provided in the pump body, and the inlet direction of the input end of the pump body is tangent to the inner wall of the circular cavity. A drainage pipe is fixedly embedded on the end face of the pump body away from the lower rotating shaft, and the bottom end of the drainage pipe is connected to the urban drainage system.

[0014] The embodiment of the present invention further provides a method for using an underground drainage treatment device in a city park, comprising the following steps:

[0015] Step 1: Pre-bury the well seat at the sewer wellhead. Rainwater leaks through the filter holes and is collected in the water storage tank for buffering. The floating block lifts the lever to pass through the filter holes.

[0016] Step 2: When the accumulated water in the water storage tank reaches a certain depth, the second float and the first float float up one after another. The first float drives the counterweight rod to move up to the top of the inclined groove. Under the elastic force of the spring, the right-angle plate drives the water baffle to stagger with the input end of the pump body, and the accumulated water enters the pump body and is discharged;

[0017] Step 3: During the process of draining the accumulated water, the fan blades are driven by the water flow to rotate, driving the wheel to rotate. After the belt transmission, the driving fan gear is engaged with the two racks in turn, which can drive the rectangular frame to move back and forth. The limit plate pushes the lever to move back and forth to remove the debris blocking the upper side of the water filter hole;

[0018] Step 4. After the liquid level in the water storage tank drops to the warning depth, the inclined rod tilts and pulls the pull rope to move the right-angle plate, and the counterweight rod moves to the top of the inclined groove. The counterweight rod squeezes the bottom wall of the inclined groove under the action of gravity, and the locking plate pushes the right-angle plate to reset. The right-angle plate drives the water baffle to block the input end of the pump body, and the liquid level in the water storage tank rises again.

[0019] It can be seen from the above technical solution that the beneficial effects of the present invention are as follows:

[0020] In rainy weather, the present invention allows rainwater to seep through the filter holes and be collected in the water storage tank for buffering. The float lifts the lever to pass through the filter holes. After the liquid level in the water storage tank drops, the float and the lever retract into the water storage tank, making it no different from a normal manhole cover and not affecting the normal passage of pedestrians in the city park.

[0021] During the process of draining the accumulated water, the fan blades are driven by the water flow to rotate, driving the rotating wheel to rotate. After the belt is driven, the driving fan gear is engaged with the two racks in turn, which can drive the rectangular frame to move back and forth. The limit plate drives the lever to move back and forth, and the debris blocking the upper side of the water filter hole is pushed away, avoiding the situation where the water filter hole is blocked by dead branches and fallen leaves, and can take into account the dual effects of filtering effect and drainage efficiency.

[0022] The present invention waits for the accumulated water cached in the water storage tank to reach a certain depth, the second float and the first float float up one after another, and the first float drives the counterweight rod to move up to the top of the inclined groove. Under the elastic force of the spring, the right-angle plate drives the water baffle to be staggered with the input end of the pump body, and the accumulated water enters the pump body for discharge. After the liquid level in the water storage tank drops to the warning depth, the inclined rod presses the counterweight rod to move to the corner of the vertical groove, and the counterweight rod squeezes the bottom wall of the inclined groove under the action of gravity, and the locking plate pushes the right-angle plate to reset, and the right-angle plate drives the water baffle to block the input end of the pump body. The liquid level in the water storage tank rises again, and the accumulated water is emptied when the water pressure in the water storage tank is sufficient. The impact force of the water flow can ensure the anti-blocking effect of the lever, and can prevent small impurities in the accumulated water from clogging the pipe, thereby avoiding the accumulation of impurities. It can also play a flushing role on the urban drainage system, reducing the maintenance burden of the drainage system. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0032] Example: Figures 1 to 6 As shown, the present embodiment provides an underground drainage treatment device for a city park, comprising a water storage tank 1, a well base 2 being fixedly connected to the upper side of the water storage tank 1, and a well cover 3 being hingedly connected to the upper side of the well base 2;

[0033] Specifically, a well groove is provided in the middle of the well seat 2, and a countersunk groove is provided on the upper part of the well groove. A manhole cover 3 is hinged at one end of the countersunk groove, and the thickness of the manhole cover 3 is consistent with the depth of the countersunk groove. After closing the manhole cover 3, the manhole cover 3, the well seat 2 and the road surface are flush, and do not affect the passage. It is worth mentioning that a recessed groove is provided on the upper side of the end of the manhole cover 3 away from the hinged position, and a pull ring is connected between the inner walls on both sides of the recessed groove. After pulling out the pull ring, the manhole cover 3 can be opened to facilitate cleaning of the water storage tank 1.

[0034] A pump body 4 is fixedly connected to one side of the bottom of the water storage tank 1. A circular cavity is provided in the pump body 4, and the inlet direction of the input end of the pump body 4 is tangent to the inner wall of the circular cavity. A drainage pipe 41 is fixedly embedded on the end surface of the pump body 4 away from the lower rotating shaft 71. The bottom end of the drainage pipe 41 is connected to the urban drainage system.

[0035] Specifically, the water flow entering from the input end of the pump body 4 can impact the inner wall of the circular cavity, forming a vortex in the pump body 4. The vortex can drive the fan blades 72 to rotate, capture the kinetic energy of the water flow, and the excess water is discharged to the urban drainage system through the drain pipe 41 to flush the sewer pipe.

[0036] A pressure relief assembly 5 is installed at the connection between the input end of the pump body 4 and the water storage tank 1. The pressure relief assembly 5 includes two guide bars 51 fixed to the inner wall of one side of the water storage tank 1. A water baffle 52 is slidably connected between the two guide bars 51. A right-angle plate 53 is fixedly connected to one side of the water baffle 52. A guide rod 54 is slidably embedded in the middle of the right-angle plate 53. One end of the guide rod 54 is fixedly connected to the inner wall of the water storage tank 1. The outside of the guide rod 54 is located between the right-angle plate 53 and the storage tank. A spring 55 is sleeved between the inner walls of the water tank 1, and a locking plate 56 is fixedly connected to one side of the top end of the right-angle plate 53. A locking groove 57 is provided on the locking plate 56. A counterweight rod 58 is slidably embedded in the locking groove 57, and one end of the counterweight rod 58 is slidably embedded in the vertical groove 59, wherein the vertical groove 59 is provided on the inner wall of the water storage tank 1, and the locking groove 57 is composed of a horizontal groove and an inclined groove that are interconnected, and a first float 510 is sleeved on the outer side of the counterweight rod 58.

[0037] When the accumulated water cached in the water storage tank 1 reaches a certain depth, the first float 510 floats up, and the first float 510 drives the counterweight rod 58 to move up to the top of the inclined groove. Under the elastic force of the spring 55, the right-angle plate 53 drives the water baffle 52 to be staggered with the input end of the pump body 4, and the accumulated water enters the pump body 4 and is discharged. On the contrary, in the early stage of the liquid level dropping in the water storage tank 1, the counterweight rod 58 is blocked by the horizontal groove and will not drive the locking plate 56 to move. During this process, the water storage tank 1 can maintain a continuous and effective drainage effect.

[0038] The pressure relief assembly 5 also includes a hinged seat 511 fixed to the bottom wall of the water storage tank 1, and a diagonal rod 512 is hinged on the hinged seat 511. A second float 513 is fixed to the middle of the diagonal rod 512, and a pull rope is fixedly connected between the second float 513 and the right-angle plate 53.

[0039] After the liquid level in the water storage tank 1 drops to the warning water level, the inclined rod 512 moves downward under the action of its own inclination angle and gravity. It is worth noting that the hinged seat 511 can limit the maximum inclination angle of the inclined rod 512, and the maximum inclination angle is less than 90°, so that the inclined rod 512 can tilt to the side away from the right-angle plate 53 each time. The right-angle plate 53 can be pulled by a pull rope to make the counterweight rod 58 re-positioned at the top of the inclined groove. The counterweight rod 58 squeezes the bottom wall of the inclined groove under the action of gravity, and the locking plate 56 pushes the right-angle plate 53 to reset. The right-angle plate 53 drives the water baffle 52 to block the input end of the pump body 4, and the liquid level in the water storage tank 1 rises again. Conversely, when the liquid level in the water storage tank 1 rises, the inclined rod 512 is lifted under the action of the second float 513.

[0040] A reciprocating assembly 6 is installed on the inner wall of one side of the water storage tank 1, and a plurality of water filter holes 31 are arranged in an array on the manhole cover 3. The water filter holes 31 are designed in a strip-shaped structure, and the water filter holes 31 are arranged corresponding to the driving rod 8. The bottom end of the driving rod 8 is fixedly connected with a floating block 81, so that when the liquid level in the water storage tank 1 rises, the floating block 81 lifts the driving rod 8 to pass through the water filter hole 31. The reciprocating assembly 6 includes two guide rails 61 fixed on the inner wall of one side of the water storage tank 1, and a rectangular frame 62 is slidably connected between the two guide rails 61. A plurality of limit plates 63 are fixedly connected to one side of the rectangular frame 62. A plurality of vertical holes are provided on the limit plates 63, and a driving rod 8 is slidably embedded between the upper and lower vertical holes. A limit block 82 is fixedly sleeved on the outside of the driving rod 8 and below the limit plate 63.

[0041] Rainwater leaks through the filter hole 31 and is cached in the water storage tank 1. The float 81 lifts the lever 8 to pass through the filter hole 31. Conversely, the liquid level in the water storage tank 1 drops, and the float 81 and the lever 8 drop synchronously, which is no different from a normal manhole cover 3 and will not affect the normal passage of pedestrians in the city park.

[0042] The reciprocating assembly 6 further includes two racks 64 respectively fixed on the upper and lower inner walls of the rectangular frame 62, a sector gear 65 is provided between the two racks 64, and the sector gear 65 is engaged with the two racks 64 in turn, and an upper rotating shaft 66 is fixedly sleeved in the middle of the sector gear 65, and the upper rotating shaft 66 is provided outside the water storage tank 1;

[0043] The upper rotating shaft 66 drives the sector gear 65 to rotate in one direction, driving the sector gear 65 to engage with the two racks 64 in turn, which can drive the rectangular frame 62 to move back and forth. The limit plate 63 pushes the lever 8 to move back and forth to remove the debris blocking the upper side of the water filter hole 31.

[0044] A transmission assembly 7 is connected between the pump body 4 and the reciprocating assembly 6. The reciprocating assembly 6 is provided with a plurality of shifting rods 8. The transmission assembly 7 includes a lower rotating shaft 71 rotatably embedded in the inner wall of one side of the pump body 4. The outer side of the lower rotating shaft 71 and the portion located inside the pump body 4 are fixedly connected to a plurality of fan blades 72. One end of the lower rotating shaft 71 and one end of the upper rotating shaft 66 are both fixedly connected to a rotating wheel 73. A belt 74 is connected between the two rotating wheels 73.

[0045] The fan blades 72 are pushed by the water flow to drive the lower rotating shaft 71 to rotate, and the lower rotating shaft 71 drives the rotating wheel 73 to rotate. The rotating wheel 73 can drive the upper rotating shaft 66 to rotate after being driven by the belt 74, thereby playing a transmission role.

[0046] The method for using the urban park underground drainage treatment device includes the following steps:

[0047] Step 1: Pre-bury the well seat 2 at the sewer wellhead. Rainwater leaks through the filter holes 31 and is collected in the water storage tank 1 for buffering. The floating block 81 lifts the lever 8 to pass through the filter holes 31.

[0048] Step 2: When the accumulated water in the water storage tank 1 reaches a certain depth, the second float 513 and the first float 510 float up one after another. The first float 510 drives the counterweight rod 58 to move up to the top of the inclined groove. Under the elastic force of the spring 55, the right-angle plate 53 drives the water baffle 52 to stagger with the input end of the pump body 4, and the accumulated water enters the pump body 4 and is discharged;

[0049] Step 3: During the process of draining the accumulated water, the fan blades 72 are driven by the water flow to rotate, driving the runner 73 to rotate. After being transmitted by the belt 74, the driving sector gear 65 is engaged with the two racks 64 in turn, which can drive the rectangular frame 62 to move back and forth. The limit plate 63 pushes the lever 8 to move back and forth, and the debris blocking the upper side of the water filter hole 31 is pushed away;

[0050] Step 4. After the liquid level in the water storage tank 1 drops to the warning depth, the inclined rod 512 tilts and pulls the pull rope to move the right-angle plate 53, and the counterweight rod 58 moves to the top of the inclined groove. The counterweight rod 58 squeezes the bottom wall of the inclined groove under the action of gravity, and the locking plate 56 pushes the right-angle plate 53 to reset. The right-angle plate 53 drives the water baffle 52 to block the input end of the pump body 4, and the liquid level in the water storage tank 1 rises again.

[0051] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacement may be a replacement of a portion of a structure, device, or method step, or it may be a complete technical solution. Any equivalent replacement or modification based on the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
