Technical Field

[0001] The present application relates to the technical field of drainage wells, and in particular to a rain screen well cover. Background Art

[0002] Rain screen, also called cover plate, manhole cover, etc., is a device used to collect and discharge rainwater. At present, the most common rain screen is ductile iron rain screen, which has high strength, plasticity, toughness, wear resistance and other properties, and is used in some high-load occasions, such as urban expressways and urban trunk roads.

[0003] Existing rain screens usually have two shapes, rectangular or circular. Wherein, the rectangular rain screen is usually arranged on both sides of the main roads in the city, and the top of the rain screen is provided with a plurality of drainage holes for supplying water to flow to the underground drainage pipe at intervals.

[0004] However, in order to improve the drainage efficiency, the design size of the drainage hole is usually large, so that in the absence of rain, it is easy for leaves, garbage and other debris to enter the underground pipe through the drainage hole and accumulate. In rainy weather, it is easy to cause the underground pipe drainage problem. Utility Model Content

[0005] In order to reduce the probability of drainage blockage in underground pipes during rainy weather, the present application provides a rain screen manhole cover.

[0006] The rain screen manhole cover provided in this application adopts the following technical solution:

[0007] A rain screen manhole cover comprises a rain screen body, a mounting seat which is lifted and lowered at the bottom of the rain screen body, a lifting assembly connecting the rain screen body and the mounting seat, a water collecting cylinder which is arranged at the bottom of the mounting seat and is connected to the top of the rain screen body, the rain screen body is provided with first through holes which penetrate through the end faces on both sides at intervals, a circulation valve is arranged at the bottom of the water collecting cylinder, the mounting seat has a sealing protrusion which extends to the first through hole, the sealing protrusion completely blocks the first through hole, and the top of the rain screen body has a circulation groove which is connected to the water collecting cylinder.

[0008] By adopting the above technical solution, the mounting seat is lifted and installed at the bottom of the rain screen body, and the sealing protrusion of the mounting seat completely blocks the first through hole. Under normal circumstances, the probability of fallen leaves or garbage entering the underground pipeline is reduced.

[0009] When it rains, the accumulated water enters the water collecting barrel. As the amount of water in the water collecting barrel increases, the water collecting barrel drives the mounting seat to descend, releasing the sealing protrusion from blocking the first through hole. The first through hole is connected, which increases the drainage speed and alleviates the water collection problem.

[0010] Optionally, the top of the rain screen body has a water collection groove corresponding to the water collection tube, the bottom wall of the water collection groove is provided with a plurality of second through holes connected to the water collection tube, and the circulation groove is connected to the water collection groove.

[0011] By adopting the above technical solution and setting up the water collection tank, the accumulated water can be stored in the water collection tank to a certain extent, thereby improving the sinking efficiency of the water collecting tube.

[0012] Optionally, the bottom wall of the circulation groove gradually slopes downward from the edge of the rain screen body toward the water collection groove.

[0013] By adopting the above technical solution, the inclined setting of the bottom wall of the circulation groove can improve the efficiency of water accumulation in the water accumulation groove, and further improve the sinking efficiency of the water collecting tube.

[0014] Optionally, the side wall of the water collecting cylinder is provided with a mud discharge side hole communicating with the inner and outer side walls, and a sealing member is provided to seal the mud discharge side hole.

[0015] By adopting the above technical solution and setting the mud discharge side holes, when the drainage is completed, the seal is removed from the water collecting barrel, so that the mud and sand in the water collecting barrel are discharged from the mud discharge side holes, thereby improving the efficiency of cleaning the water collecting barrel.

[0016] Optionally, it further comprises a rain screen frame fixed to the ground, and the side wall of the rain screen body is provided with a hinge joint hinged to the rain screen frame.

[0017] By adopting the above technical solution, the rain screen body is hinged in the rain screen frame, which is convenient for maintenance personnel to rotate and open the rain screen body, and then remove the water collecting cylinder under the mounting seat to clean up the internal debris, thereby increasing the service life of the water collecting cylinder.

[0018] Optionally, the mud discharge side hole is located on a side of the water collecting cylinder close to the hinged joint.

[0019] By adopting the above technical solution, the mud discharge side hole is set on the side of the water collecting barrel close to the hinge head, so that after the user rotates to open the rain screen body, the mud discharge side hole is located below the water collecting barrel. At this time, the seal is opened and the water in the water collecting barrel can be directly discharged, making drainage convenient.

[0020] Optionally, the rain screen frame is provided with a clearance groove corresponding to the lifting assembly in a direction away from the hinge joint.

[0021] By adopting the above technical solution and setting the giving way groove, when the rain screen body is rotated, the probability of interference between the two lifting components of the mounting seat away from the hinge joint and the rain screen frame is reduced, so that the rain screen body can be completely rotated out of the wellhead, the rain screen body and the rain screen frame can be at 90 degrees, and the accumulated water in the water collection barrel can be completely discharged.

[0022] Optionally, the lifting assembly includes a fixed column fixed to the bottom of the rain screen body, a limiting gasket arranged at the end of the fixed column, and an elastic member sleeved on the fixed column, and the mounting seat has a sliding through hole for the fixed column to slide through, and the two ends of the elastic member respectively abut the limiting gasket and the mounting seat.

[0023] By adopting the above technical scheme, the structural composition of the lifting assembly is specifically disclosed, one end of the fixed column is fixed to the bottom of the rain screen body, the mounting seat and the fixed column are slidably matched, and the elastic member arranged between the mounting seat and the bottom of the fixed column can support the mounting seat, so that the mounting seat has a tendency to always move upward, ensuring that when there is no water accumulation or less water accumulation, the sealing protrusion always has a sealing effect on the first through hole.

[0024] Optionally, the bottom of the mounting seat has a positioning groove for installing the water collecting cylinder.

[0025] By adopting the above technical solution and setting the positioning groove, it is convenient for the installer to fix the water collecting cylinder on the mounting seat, thereby improving the installation efficiency of the water collecting cylinder.

[0026] Optionally, a positioning ring portion for abutting against the positioning groove is provided at the open end of the water collecting tube, and the water collecting tube is provided with locking bolts for connecting the rain screen body around the positioning ring portion.

[0027] By adopting the above technical solution and setting the positioning ring, the contact area between the water collecting tube and the positioning groove can be increased, the positioning abutment effect can be improved, and then the locking can be performed by means of locking bolts, so that the connection strength is high.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The present application completely blocks the first through hole through the sealing protrusion, thereby reducing the probability of leaves or garbage entering the underground pipeline;

[0030] 2. The present application improves the efficiency of water accumulation in the water collection tank by setting the flow tank tilted, and further improves the sinking efficiency of the water collection tube;

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The embodiment of the present application discloses a rain screen manhole cover.

[0039] Reference Figure 1 and Figure 2 A rain screen manhole cover comprises a rain screen body 1, a mounting seat 2 which is lifted and arranged at the bottom of the rain screen body 1, a water collecting cylinder 3 which is fixed at the bottom of the mounting seat 2, a lifting component 4 which connects the rain screen body 1 and the mounting seat 2, and a rain screen frame 5 on which the rain screen body 1 is hingedly mounted.

[0040] The rain comb body 1 is in the shape of a rectangular plate as a whole, and a plurality of first through holes 11 for the accumulation of water are arranged at intervals along the length direction of the rain comb body 1. The first through holes 11 are rectangular holes arranged along the width direction of the rain comb body 1.

[0041] The top of the rain screen body 1 has a water collection groove 12 corresponding to the water collection barrel 3, and the cross section of the water collection groove 12 is circular. The bottom wall of the water collection groove 12 has a plurality of second through holes 121 that penetrate the two side end surfaces and allow the accumulated water to flow to the water collection barrel 3. The second through holes 121 are circular holes, including a center hole located at the center of the circle and side holes arranged at intervals along the circumference of the center hole. The inner diameter of the center hole is larger than the inner diameter of the side holes.

[0042] The top of the rain screen body 1 is provided with a flow slot 13 connected to the water storage tank 12. The flow slot 13 is a strip-shaped slot, and is symmetrically arranged on both sides of the water storage tank 12 along the length direction of the rain screen body 1. The bottom wall of the flow slot 13 has a guide slope for guiding the flow of the accumulated water, that is, the bottom wall of the flow slot 13 gradually tilts downward from both sides of the rain screen body 1 to the water storage tank 12. Among them, the top surfaces of the rain screen body 1 on both sides of the flow slot 13 are tilted downward toward the water storage tank 12, and the tilt angle is between 1-3 degrees.

[0043] Reference Figure 2 and Figure 3 The mounting seat 2 is in the shape of a rectangular plate as a whole, and the mounting seat 2 is vertically lifted relative to the rain screen body 1 through the lifting assembly 4. A sealing protrusion 21 corresponding to the first through hole 11 is integrally provided on the top of the mounting seat 2. The top area of ​​the sealing protrusion 21 is equal to the area of ​​the first through hole 11, so that the sealing protrusion 21 can completely cover the first through hole 11. Under normal weather conditions, the probability of garbage such as fallen leaves and stones on the road surface entering the underground water pipe from the first through hole 11 is reduced.

[0044] The bottom of the water collecting barrel 3 has a water flow hole 31 penetrating the inner and outer walls, and a circulation valve 32 is sealed and installed in the water flow hole 31. The setting of the circulation valve 32 makes the flow rate of the accumulated water in the water collecting barrel 3 to the underground drainage pipe slow down. When there is no accumulated water or the amount of accumulated water is small, the lifting assembly 4 is at rest or at a low descending height relative to the rain screen body 1, and the sealing protrusion 21 completely blocks the first through hole 11, and the accumulated water only flows to the underground drainage pipe through the water collecting barrel 3.

[0045] The side wall of the water collecting barrel 3 is provided with a mud discharge side hole 33 connecting the inside and outside, and a seal 34 for sealing the mud discharge side hole 33 is threadedly mounted on the water collecting barrel 3. The outer wall of the seal 34 has a polygonal surface that is easy to rotate. In this embodiment, the outer wall of the seal 34 is a hexagon. When the water in the water collecting barrel 3 needs to be discharged, the seal 34 is rotated to make the mud discharge side hole 33 in a connected state.

[0046] Reference Figure 3 and Figure 4 The bottom of the mounting seat 2 has a positioning groove 23 in the middle for positioning and installing the water collecting tube 3. The positioning groove 23 is annular, and the water collecting tube 3 has a positioning ring portion 35 adapted to the positioning groove 23, so as to improve the positioning and assembly efficiency of the water collecting tube 3. The positioning ring portion 35 is evenly spaced circumferentially provided with a plurality of locking bolts 36 for connecting and fixing with the mounting seat 2. In the embodiment of the present application, the positioning ring portion 35 has six locking bolts 36.

[0047] The lifting assembly 4 includes a fixing column 41 welded or bolted to the bottom of the rain screen body 1 , a limiting washer 42 arranged at one end of the fixing column 41 away from the rain screen body 1 , and an elastic member 43 sleeved on the fixing column 41 .

[0048] The mounting seat 2 has a sliding through hole 22 for the fixing column 41 to slide through. The two ends of the elastic member 43 respectively abut the bottom surface of the mounting seat 2 and the top surface of the limiting gasket 42. In this embodiment, the elastic member 43 is a spring. Among them, the limiting gasket 42 is annular, and the bottom end of the fixing column 41 is threadedly connected with a fixing screw 44 for locking the limiting gasket 42. In the embodiment of the present application, a total of four groups of lifting components 4 are arranged on the rain screen body 1, and the four groups of lifting components 4 are respectively arranged at the four corners of the mounting seat 2.

[0049] When the amount of accumulated water is large, the amount of water in the water collecting cylinder 3 increases, driving the elastic member 43 to begin to compress downward. The downward movement of the mounting seat 2 and the water collecting cylinder 3 causes the sealing protrusion 21 to separate from the first through hole 11. At this time, the first through hole 11 is in a connected state, and the accumulated water on the road surface can be transported to the underground pipeline through the first through hole 11, thereby improving the drainage efficiency on the road surface.

[0050] One side of the rain screen body 1 in the length direction is hinged to the rain screen frame 5. Two hinged heads 14 are integrally provided on the side wall of the rain screen body 1 along the length direction. The hinged head 14 is columnar, and a hinge shaft 141 extends axially in the middle of both ends. The rain screen frame 5 has a hinge groove 51 corresponding to the hinged head 14, and a rotating hole for rotating the hinge shaft 141 is provided on the hinge groove 51. Among them, the mud discharge side hole 33 on the water collecting barrel 3 is located on the side of the water collecting barrel 3 close to the hinged head 14. After the user rotates to open the rain screen body 1, the mud discharge side hole 33 is located on the side of the water collecting barrel 3 facing the bottom surface, and the mud and sand in the water collecting barrel 3 can be directly discharged from the mud discharge side hole 33.

[0051] The rain screen frame 5 also has a clearance groove 52 on one side away from the hinge groove 51 . The clearance groove 52 is rectangular so that when the rain screen body 1 is rotated upward, the two lifting components 4 at the bottom of the rain screen body 1 away from the hinge 14 will not interfere with the clearance groove 52 .

[0052] The implementation principle of a rain screen manhole cover in an embodiment of the present application is as follows: when there is no accumulated water or the amount of accumulated water is small, the sealing protrusion 21 blocks the first through hole 11. At this time, the accumulated water passes through the water collecting tube 3 to the underground drainage pipe, and the amount of water in the water collecting tube 3 cannot cause the sealing protrusion 21 to be separated from the first through hole 11; when the amount of accumulated water is large, a large amount of water enters the water collecting tube 3, so that the water outflow at the bottom of the water collecting tube 3 is much smaller than the water inflow, and the weight of the water collecting tube 3 becomes larger, causing the water collecting tube 3 and the mounting seat 2 to drop synchronously, the sealing protrusion 21 to be separated from the blocking state, and the first through hole 11 is in a connected state and starts to drain water; after the accumulated water is drained, the water in the water collecting tube 3 gradually flows out under the action of the circulation valve 32, so that the mounting seat 2 is reset.

[0053] When the user needs to quickly drain the water in the water collecting barrel 3 , the user rotates the rain screen body 1 upwards and then opens the sealing member 34 , so that the water in the water collecting barrel 3 is quickly drained from the mud discharge side hole 33 .

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
