Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, and particularly relates to a sewer manhole cover with adjustable flow rate for a sponge city. Background Technique

[0002] A sewer manhole cover is a facility used to cover a road or a deep well at home. Its main functions are to prevent people or objects from falling and to drain the road surface water to ensure the safety of pedestrians and vehicles. In addition, the sewer manhole cover also plays a very important role in the road and sidewalk drainage systems. When installing the manhole cover, it is necessary to ensure that the manhole cover is flush with the road surface to avoid the manhole cover sinking or protruding, which affects the traffic safety of pedestrians and vehicles. In addition, in order to maintain the drainage function, drainage holes need to be opened on the manhole cover.

[0003] However, at present, the drainage holes of sewer manhole covers generally have a small number and the number of drainage holes is fixed, or in order to facilitate drainage, the openings of the drainage holes are large. Therefore, when the rainfall is relatively large, a small number of drainage holes are not convenient for rapid drainage, and a large number of drainage holes will cause the load-bearing capacity of the sewer manhole cover to decrease, and road debris is easily dropped into the sewer. When the opening of the drainage hole is large, there will be certain safety hazards. Therefore, it is necessary to propose a sewer manhole cover with adjustable flow rate for a sponge city. Content of the Utility Model

[0004] An object of the utility model is to provide a sewer manhole cover with adjustable flow rate for a sponge city, so as to solve the technical problem that the flow rate of the existing sewer manhole cover is not adjustable.

[0005] Another object of the utility model is to improve the warning effect of the sewer manhole cover.

[0006] According to the object of the utility model, the utility model provides a sewer manhole cover with adjustable flow rate for a sponge city, comprising:

[0007] A manhole cover body, comprising a strip-shaped drainage opening and at least one group of drainage hole groups, each group of drainage hole groups comprising a plurality of drainage holes;

[0008] A displacement assembly, comprising a displacement lead screw and a support plate. One end of the displacement lead screw is arranged in the strip-shaped drainage opening. The support plate comprises a fixedly connected support part and a connecting part. The top of the support part is provided with a plurality of protrusions, each protrusion corresponding to one of the drainage holes. The connecting part is provided with a connecting hole for passing through the displacement lead screw. When the displacement lead screw rotates, it drives the support plate to move, so that the protrusions block or open the drainage holes;

[0009] The fixed plate includes a fixed groove extending in the vertical direction and an opening adapted to the connecting portion. The displacement lead screw is fixedly installed in the fixed groove, and the connecting portion is arranged to pass through the opening and connect with the supporting portion, so that when the displacement lead screw rotates, it drives the supporting portion to move.

[0010] Optionally, the manhole cover body further includes at least one limiting groove and at least one connecting screw hole, and the sewer manhole cover further includes:

[0011] At least one warning assembly located in the limiting groove. The warning assembly includes a warning plate and a connecting screw. The connecting screw is arranged at the end of the warning plate. The warning plate has a warning state in which the connecting screw cooperates with the connecting screw hole and a safe state in which the connecting screw is separated from the connecting screw hole and is located in the limiting groove.

[0012] Optionally, the warning plate is provided with a first mounting hole, and the bottom of the limiting groove is provided with a second mounting hole. The first mounting hole and the second mounting hole are arranged correspondingly, so as to connect the warning plate and the manhole cover body by passing a fastener through the first mounting hole and the second mounting hole.

[0013] Optionally, the displacement lead screw includes:

[0014] A handle located at the top of the fixed plate. The top of the handle is provided with a cross groove.

[0015] Optionally, the supporting portion has a U-shaped structure.

[0016] Optionally, the multiple drainage holes in each drainage hole group are arranged at equal intervals along a direction perpendicular to the extension direction of the strip-shaped drainage opening.

[0017] Optionally, the sewer manhole cover further includes:

[0018] A connecting frame having an annular structure. The connecting frame is sleeved on the circumferential side of the manhole cover body.

[0019] Optionally, the connecting frame includes at least one mounting position for mounting the manhole cover body in the connecting frame.

[0020] Optionally, the height of the limiting groove is the same as the thickness of the warning plate.

[0021] Optionally, the supporting portion is provided with a limiting hole, and the end of the connecting portion cooperates with the limiting hole to connect the supporting portion and the connecting portion.

[0022] The utility model adjusts the drainage speed of the sewer manhole cover by arranging a displacement component in the strip-shaped drainage opening. When the displacement lead screw of the displacement component rotates, it drives the support plate of the displacement component to move, so that the protrusion blocks or opens the drainage hole. That is, when the displacement lead screw rotates to control the support plate to move upward until the protrusion completely cooperates with the drainage hole, the drainage hole is in a blocked state to reduce the drainage flow rate of the sewer manhole cover. At the same time, the cooperation between the protrusion and the drainage hole can reduce the emission of peculiar smell in the sewer to a certain extent, and can also push out the blocked sundries in the drainage hole when the drainage hole is blocked by sundries. When the displacement lead screw rotates to control the support plate to move downward until the protrusion completely separates from the drainage hole, the drainage hole is in an open state to increase the drainage flow rate of the sewer manhole cover, thus avoiding the situation that water cannot be drained when there is too much water accumulation on the road surface.

[0023] Furthermore, the utility model arranges a warning component and a limit groove on the top of the manhole cover body. When the warning plate of the warning component is in a warning state, that is, the connecting screw of the warning component cooperates with the connecting screw hole on the top of the manhole cover body to support the warning plate so that the warning plate is in an erected warning state, thus warning pedestrians that there is water accumulation here and they need to drive carefully or take a detour. When the warning plate is in a safe state, that is, the connecting screw of the warning component separates from the connecting screw hole on the top of the manhole cover body, the warning plate is fixedly installed in the limit groove so that the height of the warning plate is flush with that of the limit groove, avoiding bumps when pedestrians drive past the sewer manhole cover, thereby improving the safety of the sewer manhole cover.

[0038] Figure 1 is a schematic overall structural diagram of a sewer manhole cover according to an embodiment of the present invention. Figure 2 is a schematic structural diagram of a displacement assembly according to an embodiment of the present invention. Figure 3 is a schematic installation diagram of a displacement assembly according to an embodiment of the present invention.

[0039] As Figure 1 shown, an embodiment of the present invention provides an adjustable-flow-rate sewer manhole cover 100 for a sponge city. The sewer manhole cover 100 includes a manhole cover body 10, a displacement assembly 20, and a fixing plate 30. The manhole cover body 10 includes a strip-shaped drainage opening 11 and at least one group of drainage holes 12. Each group of drainage holes 12 includes a plurality of drainage holes 121. The displacement assembly 20 includes a displacement lead screw 21 and a support plate 22. One end of the displacement lead screw 21 is disposed in the strip-shaped drainage opening 11. The support plate 22 includes a fixedly connected support portion 221 and a connecting portion 222. The top of the support portion 221 is provided with a plurality of protrusions 223. Each protrusion 223 is arranged corresponding to one drainage hole 121. The connecting portion 222 is provided with a connection hole for passing through the displacement lead screw 21. When the displacement lead screw 21 rotates, it drives the support plate 22 to move so that the protrusions 223 block or open the drainage holes 121. The fixing plate 30 extends in the vertical direction. The fixing plate 30 includes a fixing groove 31 extending in the vertical direction and an opening 32 adapted to the connecting portion 222. The displacement lead screw 21 is fixedly installed in the fixing groove 31, and the connecting portion 222 is arranged to pass through the opening 32 and connect with the support portion 221 so that when the displacement lead screw 21 rotates, it drives the support portion 221 to move. Here, the number of groups of drainage holes 12 can be one or more.

[0040] In this embodiment, the sewer manhole cover 100 includes a strip-shaped drainage opening 11 and at least one set of drainage holes 12. By arranging a displacement assembly 20 in the strip-shaped drainage opening 11, when the displacement lead screw 21 of the displacement assembly 20 rotates, it drives the support plate 22 of the displacement assembly 20 to move, so that the protrusion 223 blocks or opens the drainage hole 121 to adjust the drainage speed of the sewer manhole cover 100. That is, when the displacement lead screw 21 rotates to control the support plate 22 to move upward until the protrusion 223 is fully engaged with the drainage hole 121, the drainage hole 121 is in a blocked state to reduce the drainage flow rate of the sewer manhole cover 100. At the same time, the cooperation between the protrusion 223 and the drainage hole 121 can reduce the emission of odors in the sewer to a certain extent, and can also eject the blocked debris in the drainage hole 121 when the drainage hole 121 is blocked by debris. When the displacement lead screw 21 rotates to control the support plate 22 to move downward until the protrusion 223 is completely separated from the drainage hole 121, the drainage hole 121 is in an open state to increase the drainage flow rate of the sewer manhole cover 100, thereby avoiding the situation where accumulated water on the road surface cannot be drained when there is too much accumulated water.

[0041] In this embodiment, the sewer manhole cover 100 further includes a fixing plate 30. The fixing plate 30 includes a fixing groove 31 extending in the vertical direction and a guiding groove adapted to the connecting portion 222. The displacement lead screw 21 is arranged to pass through the fixing groove 31 and the connecting portion 222 is connected to the supporting portion 221 through the guiding groove, so that when the displacement lead screw 21 rotates, it drives the supporting portion 221 to move. The width of the connecting portion 222 is the same as the width of the guiding groove, so that the connecting portion 222 is clamped in the guiding groove to limit the connecting portion 222, preventing the connecting portion 222 from rotating during the process of driving the connecting portion 222 to move when the displacement lead screw 21 rotates, and avoiding the protrusion 223 on the supporting portion 221 connected to the connecting portion 222 from being misaligned with the drainage hole 121, thereby avoiding affecting the flow rate adjustment efficiency of the sewer manhole cover 100.

[0042] Figure 4 is a schematic structural diagram of a warning component according to an embodiment of the present invention, Figure 5 is a schematic structural diagram of the warning component in an open state according to an embodiment of the present invention.

[0043] Such as Figure 4As shown, in a further embodiment, the manhole cover body 10 further includes at least one limiting groove 40 and at least one connecting screw hole 50. The sewer manhole cover 100 further includes at least one warning component 60. The warning component 60 is located in the limiting groove 40. The warning component 60 includes a warning plate 61 and a connecting screw 62. The connecting screw 62 is arranged at the end of the warning plate 61. The warning plate 61 has a warning state in which the connecting screw 62 cooperates with the connecting screw hole 50 and a safety state in which the connecting screw 62 is separated from the connecting screw hole 50 and is located in the limiting groove 40. Here, the number of the warning components 60 is two, and the two warning components 60 are symmetrically distributed on both sides of the top of the manhole cover body 10.

[0044] As Figure 1 shown, in this embodiment, by arranging the warning component 60 and the limiting groove 40 on the top of the manhole cover body 10, when the warning plate 61 of the warning component 60 is in the warning state, that is, the connecting screw 62 of the warning component 60 cooperates with the connecting screw hole 50 on the top of the manhole cover body 10 to support the warning plate 61 so that the warning plate 61 is in an upright warning state, thereby warning pedestrians that there is water accumulation here and they need to be cautious or take a detour. When the warning plate 61 is in the safety state, that is, the connecting screw 62 of the warning component 60 is separated from the connecting screw hole 50 on the top of the manhole cover body 10, the warning plate 61 is fixedly installed in the limiting groove 40 so that the height of the warning plate 61 is flush with that of the limiting groove 40, avoiding bumps when pedestrians pass by the sewer manhole cover 100, thereby improving the safety of the sewer manhole cover 100.

[0045] As Figure 5 shown, in a further embodiment, the warning plate 61 is provided with a first mounting hole 611, and the bottom of the limiting groove 40 is provided with a second mounting hole 41. The first mounting hole 611 and the second mounting hole 41 are arranged correspondingly so as to connect the warning plate 61 and the manhole cover body 10 by passing a fastener through the first mounting hole 611 and the second mounting hole 41. When the warning plate 61 is in the safety state, the first mounting hole 611 and the second mounting hole 41 are arranged correspondingly so that the fastener passes through the first mounting hole 611 and the second mounting hole 41 to connect the warning plate 61 and the manhole cover body 10, so that the warning plate 61 is fixedly connected to the manhole cover body 10 when in the safety state, avoiding looseness of the warning plate 61 and causing potential safety hazards.

[0046] Figure 6 is a schematic structural diagram of a handle according to an embodiment of the present invention.

[0047] As Figure 6As shown, in a further embodiment, the displacement lead screw 21 includes a handle 211 located at the top of the fixed plate 30, and a cross groove is provided at the top of the handle 211. The handle 211 is provided at the top of the fixed plate 30, making the operation simple and convenient when the displacement lead screw rotates, so as to drive the support plate 22 to move up and down smoothly, thereby improving the convenience of adjusting the flow rate of the sewer manhole cover 100. Here, the user can use a screwdriver or power tool to drive the handle 211 to rotate.

[0048] In a further embodiment, the support portion 221 has a U-shaped structure, that is, the protrusion 223 for blocking the drain hole 121 is located at the top of the two extending arms of the support portion 221. The support portion 221 is arranged in a U-shaped structure, which can not only ensure that the support portion 221 bears multiple protrusions 223, but also reduce the weight of the support portion 221, making the support plate 22 lightweight, thereby reducing the overall load of the sewer manhole cover 100.

[0049] In a further embodiment, the multiple drain holes 121 of each group of drain holes 12 are arranged at equal intervals along the extension direction perpendicular to the strip-shaped drain opening 11. By arranging a plurality of drain holes 121 evenly on the sewer manhole cover 100, the water flow can be more evenly dispersed when entering the drain opening, which helps to reduce the local resistance of the water flow, thereby improving the overall drainage efficiency. In addition, the evenly distributed drain holes 121 make it less likely for impurities and particles in the water flow to accumulate at specific positions, thereby reducing the risk of blockage of the drainage system.

[0050] In a further embodiment, the sewer manhole cover 100 further includes a connection frame 70, the connection frame 70 has an annular structure, and the connection frame 70 is sleeved on the peripheral side of the manhole cover body 10. The outer peripheral side of the connection frame 70 is fixedly installed at the wellhead of the road surface. The connection frame 70 is sleeved on the peripheral side of the manhole cover body 10. The connection frame 70 increases the contact area between the manhole cover and the wellhead, thereby improving the stability of the manhole cover and preventing the manhole cover from shifting or tilting during use. At the same time, the connection frame 70 forms an effective seal between the sewer manhole cover 100 and the wellhead, reducing the possibility of moisture, dust and other impurities entering the sewer. In addition, the connection frame 70 provides a convenient installation method, simplifying the installation process of positioning and fixing the manhole cover body 10 on the wellhead.

[0051] In a further embodiment, the connection frame 70 includes at least one installation position 71, and the installation position 71 is used to install the manhole cover body 10 in the connection frame 70. The installation position 71 has a groove-like structure with an opening 32 facing upward. The installation position 71 provides an operating space when the manhole cover body 10 is sunk and installed into the connection frame 70, facilitating the taking and placing of the manhole cover body 10 and improving the installation efficiency of the manhole cover body 10.

[0052] In a further embodiment, the height of the limiting groove 40 is the same as the thickness of the warning board 61. That is, when the warning board 61 is in a safe state, the warning board 61 is fixedly installed in the limiting groove 40 and the warning board 61 is flush with the limiting groove 40, avoiding bumps when pedestrians pass through the limiting groove 40 of the sewer manhole cover 100, thereby improving the comfort and safety of pedestrians when traveling on the sewer manhole cover 100.

[0053] In a further embodiment, the support portion 221 is provided with a limiting hole, and the end of the connecting portion 222 is matched with the limiting hole to connect the support portion 221 and the connecting portion 222. The end of the connecting portion 222 is matched with the limiting hole of the support portion 221 to connect the support portion 221 and the connecting portion 222, so that when the displacement lead screw 21 rotates, it drives the connecting portion 222 and the support portion 221 to move, so as to realize the cooperation or separation between the protrusion 223 on the support portion 221 and the drain hole 121, thereby adjusting the flow rate of the drain hole 121 of the sewer manhole cover 100.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0055] The above-described embodiments merely represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
