Abstract
Description
Technical Field
[0001] This utility model relates to the field of manhole cover technology, and more specifically, to a permeable concrete cover. Background Technology
[0002] Urban construction involves numerous underground pipelines, such as sewers, underground gas pipelines, water supply pipelines, power pipelines, communication pipelines, and defense pipelines. These pipelines have an outlet to the surface at intervals; this section from the pipeline to the surface is called the manhole opening. The manhole opening is usually flush with the ground and therefore requires a cover, called a manhole cover. Manhole covers are typically made of reinforced concrete, metal, or reinforced plastics, and are primarily round or square in shape. The cover usually indicates the purpose of the underground pipeline, the maintenance unit, and their telephone number.
[0003] Currently, manhole covers used in sewers mainly serve the functions of drainage and containment at the manhole opening. However, due to the relatively simple design of manhole covers, there is no effective warning structure to mark the location of the manhole when water accumulates at the opening, resulting in insufficient safety performance. Utility Model Content
[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that addresses the problem of insufficient safety performance of manhole covers due to the lack of effective warning structures to indicate the location of the manhole opening.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a permeable concrete cover, comprising a concrete manhole cover, wherein the concrete manhole cover has multiple permeable grooves, and a water guide box is bolted to the bottom of the concrete manhole cover. The water guide box is located below at least one permeable groove, and a drainage hole is provided at the bottom of the water guide box. A hollow floating plate is provided inside the water guide box, and a guide rod is fixedly connected to the bottom of the hollow floating plate, with one end of the guide rod extending movably through to the bottom of the water guide box. A buffer connection assembly is provided on the hollow floating plate, and a warning rod is provided on the buffer connection assembly.
[0006] In a preferred embodiment, the concrete manhole cover is fixedly connected to a metal frame on its periphery.
[0007] In a preferred embodiment, a drainage groove is provided on the top of the side of the water guide tank.
[0008] In a preferred embodiment, the number of guide rods is one pair, the guide rods are arranged in a T-shape, and the guide rods are slidably connected to the water guide tank.
[0009] In a preferred embodiment, the buffer connection assembly includes a sealing box, a rotating rod is rotatably connected inside the sealing box, and one end of the rotating rod extends to the outside of the sealing box. A tension spring is hooked inside the sealing box, and one end of the tension spring facing away from the sealing box is hooked to the rotating rod.
[0010] In a preferred embodiment, one end of the rotating rod is fixedly connected to a mounting block, the mounting block is fixedly connected to one end of the warning rod, the warning rod is located below one of the permeable troughs, and the warning rod is made of rubber.
[0011] In a preferred embodiment, a warning strip is fixedly connected to the outer surface of the warning bar.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This permeable concrete cover slab uses a water guide box installed under the drainable concrete manhole cover to assist in the drainage of water on the road surface. When the drainage volume of water through the concrete manhole cover is greater than the drainage volume of the water guide box, the hollow floating plate will float up and drive the warning pole through the concrete manhole cover to be erected. This makes it convenient to mark the location of water accumulation on the concrete manhole cover and is relatively safe.
[0014] 2. This permeable concrete cover, by setting a buffer connection component, utilizes the properties of the rubber material of the warning pole and the buffer connection component to provide an elastic connection for the swing direction of the warning pole when it protrudes from the concrete manhole cover. This can improve the impact resistance of the warning pole and thus increase its durability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See also Figures 1-5 This utility model provides a permeable concrete cover plate, including a concrete manhole cover 1, on which multiple permeable grooves 2 are provided.
[0023] The permeable channel 2 facilitates the passage of water on the road surface so that it can be drained into the sewer.
[0024] In this embodiment: a metal frame 9 is fixedly connected to the periphery of the concrete manhole cover 1.
[0025] The metal frame 9 can wrap around the perimeter of the concrete manhole cover 1, thus reducing the chance of the edges of the concrete manhole cover 1 breaking.
[0026] In this embodiment: the bottom of the concrete manhole cover 1 is connected to a water guide box 3 by bolts. The water guide box 3 is located below at least one permeable trough 2, and the bottom of the water guide box 3 is provided with a drainage hole 4.
[0027] The bolted water guide box 3 can increase the convenience of disassembly and assembly with the concrete manhole cover 1. The water guide box 3 is set below the permeable channel 2 to receive the surface water on the road and to assist in drainage through the drainage hole 4. In this application, the water guide box 3 is located below the two permeable channels 2 to receive the passing rainwater. There are multiple drainage holes 4, and the drainage volume of the multiple drainage holes 4 is less than the drainage volume of the two permeable channels 2. When the permeable channel 2 is in a high-flow drainage state, the water guide box 3 can be gradually filled with water.
[0028] In this embodiment, a drainage groove 10 is provided on the top of the side of the water guide tank 3.
[0029] The drainage channel 10 increases the drainage capacity of the water tank 3 at the top, so that when the water tank 3 is nearly full, the accumulated water is discharged into the sewer through the drainage channel 10.
[0030] In this embodiment: a hollow floating plate 5 is provided inside the water guide tank 3. A guide rod 6 is fixedly connected to the bottom of the hollow floating plate 5, and one end of the guide rod 6 extends movably through to the bottom of the water guide tank 3. There is a pair of guide rods 6, which are arranged in a T-shape and are slidably connected to the water guide tank 3.
[0031] The connection between the guide rod 6 and the water tank 3 can be dynamically sealed by a sealing ring, which can improve the stability of the guide rod 6 in raising and lowering. When the water tank 3 is gradually filled with water, the hollow floating plate 5 can float in the water tank 3, and the guide rod 6 can position and move the hollow floating plate 5.
[0032] In this embodiment: A buffer connection assembly 7 is provided on the hollow floating disk 5. The buffer connection assembly 7 includes a sealing box 71. A rotating rod 72 is rotatably connected inside the sealing box 71, and one end of the rotating rod 72 extends to the outside of the sealing box 71. A tension spring 73 is hooked inside the sealing box 71, and one end of the tension spring 73 facing away from the sealing box 71 is hooked to the rotating rod 72.
[0033] The pair of tension springs 73 allows the rotating rod 72 to have spring tension when rotating in both directions. The rotating rod 72 can be connected to the sealing box 71 in a sealed rotation via a sealed bearing, which increases the waterproofness of the sealing box 71.
[0034] In this embodiment: one end of the rotating rod 72 is fixedly connected to the mounting block 11, the mounting block 11 is fixedly connected to one end of the warning rod 8, the warning rod 8 is located below one of the permeable troughs 2, and the warning rod 8 is made of rubber.
[0035] In use, the concrete manhole cover 1 is placed at the sewer opening. When water is draining from the road surface and enters the sewer through the permeable channel 2, some of the accumulated water can enter the water guide tank 3 through the permeable channel 2. Because the bottom of the water guide tank 3 is equipped with drainage holes 4, the drainage holes 4 can normally assist in the drainage of the water guide tank 3. However, when the permeable channel 2 is in a high-flow-rate drainage state, that is, when the drainage volume of the permeable channel 2 is greater than the drainage volume of the multiple drainage holes 4, the water guide tank 3 can gradually be filled with accumulated water. To prevent the water guide tank 3 from overflowing... If the drainage of the permeable channel 2 is affected by the accumulation of water, the drainage channel 10 on the water guide box 3 can assist the water guide box 3 in draining water at the top position. When the water that cannot be drained in time in the water guide box 3 causes the hollow floating plate 5 to float in the water guide box 3, the hollow floating plate 5 can control the warning rod 8 to pass through the permeable channel 2 through the buffer connection component 7. By erecting the warning rod 8 on the concrete manhole cover 1, the concrete manhole cover 1 can be used as a warning to prevent pedestrians and vehicles from passing through the concrete manhole cover 1 and increasing the danger.
[0036] Similarly, when the water in the water guide tank 3 is emptied, the hollow floating plate 5, without buoyancy, can drive the warning rod 8 on the buffer connection assembly 7 to descend into the water guide tank 3, and below the position of the concrete well cover 1, so that the warning rod 8 can be easily stored.
[0037] It is worth noting that when the warning pole 8 is impacted by unplanned factors, the properties of the rubber material of the warning pole 8 can increase the impact cushioning. Furthermore, since the rotating rod 72 can provide an elastic connection for the swing direction of the warning pole 8, the warning pole 8 can swing with the permeable groove 2 as a parallel line when it is impacted. The swing direction of the warning pole 8 should be set along the length of the road by the permeable groove 2 on the concrete manhole cover 1. This can improve the impact resistance of the warning pole 8 and thus increase its durability.
[0038] In this embodiment: a warning strip 12 is fixedly connected to the outer surface of the warning rod 8.
[0039] Warning strip 12 can increase the visibility of warning bar 8.
[0040] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
