Description

Technical Field

[0001] The present application relates to the technical field of drainage wells, and in particular to an intelligent filtering rain screen. Background Art

[0002] A rain grate, also known as a manhole cover or manhole cover, is a device used to collect and drain rainwater. Ductile iron rain grate is the most common type, featuring high strength, plasticity, toughness, and wear resistance. It is used in high-load applications such as urban expressways and trunk roads.

[0003] Existing rain screens typically come in either rectangular or circular shapes. Rectangular rain screens are typically deployed on both sides of urban arterial roads. They have multiple, spaced-apart holes on their tops, which supply water to underground drainage pipes. Water accumulation on urban arterial roads is primarily concentrated along the sides, so the first holes are typically larger than those in circular rain screens. In the absence of accumulated water, larger debris can easily enter the underground drainage pipes through the first holes. When it rains, debris carried by the accumulated water mixes with previously accumulated debris, increasing the probability of underground drainage pipe blockage. Utility Model Content

[0004] In order to reduce the probability of blockage of underground drainage pipes, the present application provides an intelligent filtering rain screen.

[0005] The intelligent filtering rain screen provided by this application adopts the following technical solutions:

[0006] A smart filtering rain screen comprises a rain screen body, a mounting base arranged to be raised and lowered at the bottom of the rain screen body, a telescopic assembly connecting the rain screen body and the mounting base, a water collection cylinder arranged at the bottom of the mounting base and connected to the top of the rain screen body, the rain screen body having first through holes extending through both side end surfaces at intervals, the water collection cylinder having a circulation valve at the bottom, and is characterized in that the mounting base has a sealing protrusion extending to the first through hole, and the sealing protrusion partially blocks the first through hole.

[0007] By adopting this technical solution, the mounting base is installed at the bottom of the rain screen body in a lifting manner. The sealing protrusion of the mounting base partially blocks the first through-hole. Under normal circumstances, the area of ​​the first through-hole is reduced, which can improve the safety of pedestrians on both sides of urban roads. When the amount of accumulated water is small, the accumulated water can flow directly from the first through-hole to the underground drainage pipe. When the amount of accumulated water is large, the accumulated water enters the water collection tube. As the water level in the water collection tube increases, the mounting base and the water collection tube are lowered as a whole, allowing the sealing protrusion to release the blockage of the first through-hole, leaving the first through-hole intact and improving the drainage speed.

[0008] Optionally, the top of the rain screen body is provided with a sedimentation trough corresponding to the water collecting barrel, and the bottom wall of the sedimentation trough is provided with a second through hole communicating with the water collecting barrel.

[0009] By adopting the above technical solution and setting up the sedimentation tank, the accumulated water can be sedimented and filtered to a certain extent in the sedimentation tank, reducing the probability of larger debris entering the water collection barrel and causing blockage.

[0010] Optionally, the top of the rain screen body has a connecting groove connected to the sedimentation groove.

[0011] By adopting the above technical solution and setting the connecting groove, the accumulated water in the rain screen body can flow to the sedimentation groove through the connecting groove, thereby improving the efficiency of the accumulated water flowing into the water collection tube and improving the sinking efficiency of the water collection tube.

[0012] Optionally, the mounting seat is lifted and lowered by a telescopic assembly, and the rain screen body is provided with four groups of telescopic assemblies, which are respectively arranged at the four corners of the mounting seat.

[0013] By adopting the above technical solution, the mounting seat and the rain screen body are connected by a telescopic component. The mounting seat is raised and lowered by the telescopic component and can automatically sink according to the amount of accumulated water, thereby increasing the area of ​​the water flow hole and improving drainage efficiency.

[0014] Optionally, the telescopic assembly includes a guide column fixed to the bottom of the rain screen body, a limiting gasket arranged at the end of the guide column, and a reset spring sleeved on the guide column. The mounting seat has a sliding through hole for the guide column to slide through, and the two ends of the reset spring respectively abut the limiting gasket and the mounting seat.

[0015] By adopting the above technical solution, the structural composition of the telescopic assembly is specifically disclosed. One end of the guide column is fixed to the bottom of the rain screen body, and the mounting seat and the guide column are slidably matched. The reset spring arranged between the mounting seat and the bottom of the guide 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 the effect of blocking the first through hole.

[0016] Optionally, the bottom of the mounting seat has a positioning groove for installing the water collecting cylinder.

[0017] By adopting the above technical solution and providing 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.

[0018] Optionally, the open end of the water collecting tube is provided with a positioning ring portion for abutting against the positioning groove, and the water collecting tube is provided with connecting bolts for connecting to the rain screen body around the positioning ring portion.

[0019] By adopting the above technical solution and setting the positioning ring, the contact area between the water collecting cylinder and the positioning groove can be increased, the positioning abutment effect can be improved, and then the connection can be locked by connecting bolts, with high connection strength.

[0020] Optionally, the invention 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.

[0021] By adopting the above technical solution, the rain screen body is hinged in the rain screen frame, which makes it easy for maintenance personnel to rotate the rain screen body to open it, and then remove the water collecting cylinder under the mounting seat to clean the internal debris, thereby improving the practicality of the water collecting cylinder.

[0022] Optionally, the rain screen frame is provided with a clearance groove in a direction away from the hinge joint for the telescopic assembly to rotate.

[0023] By adopting the above technical solution and setting the clearance groove, the probability of interference between the two telescopic components of the mounting seat away from the hinge joint and the rain screen frame is reduced when the rain screen body is rotated, so that the rain screen body can be completely rotated out of the wellhead.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The present invention's rain screen filter includes a screen body, a mounting base, a water collection tube, a telescopic assembly, and a screen frame. Under normal conditions, it improves safety for pedestrians on both sides of the road and reduces the likelihood of large debris entering underground drainage pipes and causing blockages. When water accumulates significantly, the mounting base and water collection tube descend synchronously, improving drainage efficiency.

[0026] 2. The present application, through the provision of the sedimentation trough and the connecting trough, can direct the accumulated water through the connecting trough to the sedimentation trough for a certain sedimentation effect, thereby improving the sinking efficiency of the mounting base;

[0027] 3. The present application reduces the probability of interference between the telescopic assembly and the rain comb frame when the rain comb body is rotated by setting the clearance groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses an intelligent filtering rain screen.

[0035] Reference Figure 1 and Figure 2 An intelligent filtering rain screen includes a rain screen body 1, a mounting base 2 arranged at the bottom of the rain screen body 1, a water collecting cylinder 3 fixed to the bottom of the mounting base 2, a telescopic component 4 connecting the rain screen body 1 and the mounting base 2, and a rain screen frame 5 for hinged installation of the rain screen body 1.

[0036] 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 flow of accumulated water are spaced apart 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.

[0037] The top of the rain screen body 1 has a sedimentation trough 12 that corresponds to the water collection barrel 3. The sedimentation trough 12 has a circular cross-section. The bottom wall of the sedimentation trough 12 has multiple second through-holes 121 that penetrate the two end surfaces and allow accumulated water to flow into the water collection barrel 3. The second through-holes 121 can reduce the probability of larger debris entering the water collection barrel 3.

[0038] The top of the rain comb body 1 also has a connecting groove 13 connected to the sedimentation groove 12, and the connecting groove 13 is located in the middle of the width direction of the rain comb body 1. The connecting groove 13 is arranged along the length direction of the rain comb body 1 and is symmetrically arranged along the horizontal axis of the sedimentation groove 12.

[0039] The mounting base 2 is generally rectangular and plate-shaped. It is vertically adjustable relative to the rain screen body 1 via a telescopic assembly 4. A sealing protrusion 21 is integrally formed on the top of the mounting base 2, corresponding one-to-one with the first through-hole 11. The top area of ​​the sealing protrusion 21 is smaller than the area of ​​the first through-hole 11. In this embodiment, the sealing protrusion 21 is rectangular, with the same length as the first through-hole 11 and a width that is half the width of the first through-hole 11.

[0040] The telescopic assembly 4 includes a guide post 41 welded or bolted to the bottom of the rain screen body 1 , a limiting washer 42 provided at one end of the guide post 41 away from the rain screen body 1 , and a return spring 43 sleeved on the guide post 41 .

[0041] The mounting base 2 has a sliding through-hole 22 through which a guide post 41 slides. The two ends of a return spring 43 respectively abut the bottom surface of the mounting base 2 and the top surface of a stop washer 42. The stop washer 42 is annular in shape, and the bottom end of the guide post 41 is threadedly connected to a fixing screw 44 for locking the stop washer 42. In this embodiment of the present application, the rain screen body 1 is equipped with four sets of telescopic assemblies 4, one at each of the four corners of the mounting base 2.

[0042] Reference Figure 3 The center portion of the bottom surface of the mounting base 2 has a positioning groove 23 for positioning the water collection tube 3. The positioning groove 23 is annular, and the water collection tube 3 has a positioning ring portion 31 that matches the positioning groove 23 to improve the positioning and assembly efficiency of the water collection tube 3. The positioning ring portion 31 is evenly spaced circumferentially with multiple connecting bolts 32 for securing the mounting base 2. In this embodiment, the positioning ring portion 31 has six connecting bolts 32.

[0043] according to Figures 1 to 3 The bottom of the water collection tube 3 has a water flow hole 33 extending through the inner and outer walls, and a circulation valve 34 is sealed within the water flow hole 33. The provision of the circulation valve 34 slows the flow of accumulated water within the water collection tube 3 to the underground drainage pipe. When there is no accumulated water or the amount of accumulated water is small, the return spring 43 is in its normal, uncompressed state. At this time, the sealing protrusion 21 is located within the first through hole 11, partially blocking the first through hole 11. A small amount of accumulated water flows directly from the first through hole 11 to the underground drainage pipe. The amount of water in the water collection tube 3 is small, and the mounting base 2 cannot be lowered as a whole.

[0044] When the amount of accumulated water increases, the amount of water in the water collecting tube 3 increases, and the weight of the mounting base 2 and the water collecting tube 3 increases, causing the return spring 43 to begin to compress. The lowering of the mounting base 2 and the water collecting tube 3 causes the sealing protrusion 21 to disengage from the first through hole 11. At this time, the flow area of ​​the first through hole 11 increases, increasing the amount of water discharged per unit time and improving drainage efficiency.

[0045] Reference Figure 4The rain screen body 1 is hinged to the rain screen frame 5 on one side along its length. Two hinged joints 14 are integrally formed along the sidewalls of the rain screen body 1. The hinged joints 14 are cylindrical, with hinge shafts 141 extending axially from the center of each end. The rain screen frame 5 has hinge slots 51 corresponding to the hinged joints 14, and a rotation hole 511 is provided in the hinge slots 51 for rotatably mounting the hinge shafts 141. The rain screen frame 5 also has a rectangular clearance slot 52 on the side away from the hinge slot 51. This ensures that when the rain screen body 1 is rotated upward, the two telescopic components 4 at the bottom of the rain screen body 1, away from the hinged joints 14, will not interfere with the clearance slot 52.

[0046] The implementation principle of an intelligent filtering rain screen 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 partially blocks the first through hole 11. At this time, a part of the accumulated water passes through the first through hole 11 to the underground drainage pipe, and the amount of water in the water collecting cylinder 3 cannot make the sealing protrusion 21 out of the blocked state; when the amount of accumulated water is large, a large amount of water enters the water collecting cylinder 3, so that the water outflow at the bottom of the water collecting cylinder 3 is much smaller than the water inflow, and the weight of the water collecting cylinder 3 becomes larger, so that the water collecting cylinder 3 and the mounting seat 2 drop synchronously, so that the sealing protrusion 21 is out of the blocked state, and the first through hole 11 is in a complete state for drainage; after the accumulated water is drained, the water in the water collecting cylinder 3 flows out completely under the action of the circulation valve 34, so that the mounting seat 2 is reset.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
