Description

Technical Field

[0001] The utility model discloses a warning manhole cover and belongs to the technical field of manhole covers. Background Art

[0002] Manhole covers are important equipment used to close sewers, septic tanks, inspection wells and other facilities. They are usually made of cast iron, ductile iron or composite materials.

[0003] However, in some places, due to poor drainage systems or low-lying terrain, waterlogging problems often occur, resulting in waterlogging on the roads. When dealing with the waterlogging, workers need to open the manhole covers to drain the water. Due to the turbidity of the water, it becomes difficult to directly find the location of the manhole cover, which increases the difficulty of their work.

[0004] A solution is now proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a warning manhole cover in order to solve the above-mentioned problem.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a warning manhole cover, including a manhole cover body, a drainage groove and a groove are opened on the manhole cover body, the groove is connected to the drainage groove, a warning component is installed in the groove, a limiting component that can close the groove opening is installed in the drainage groove, and the limiting component can move in a direction away from the groove opening when subjected to pressure.

[0007] Preferably, the warning component includes a warning ball, which is movably installed in the groove and connected to the groove through a connecting line.

[0008] Preferably, the warning component also includes a box and a second spring, the box is slidably connected to the groove, the warning ball is specifically placed in the box and movably connected to the box through a connecting line, and both ends of the second spring are fixedly connected to the box and the groove respectively.

[0009] Preferably, the limiting assembly includes a slider and a spring 1, the slider is movably installed in the drainage groove, and the two ends of the spring 1 are respectively fixedly connected to the slider and the drainage groove.

[0010] Preferably, the drainage groove and the groove are both provided with water guide grooves communicating with the outside.

[0011] Preferably, the warning ball is coated with a reflective coating.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. This product is set up with a pressure-triggered limit component. When the water is deep, the slider is pressed downward to release the seal of the groove opening, release the warning component, and make the extremely light warning ball float out of the water to provide a warning effect.

[0014] 2. There are water guide grooves at the bottom of the grooves and drainage grooves. After the water on the road recedes, the accumulated water in the grooves can be discharged in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 , Figure 3As shown, a warning manhole cover comprises a manhole cover body 1, a drainage groove 2 and a groove 3 are provided on the manhole cover body 1, the groove 3 is connected with the drainage groove 2, a warning component is installed in the groove 3, a limiting component which can close the opening of the groove 3 is installed in the drainage groove 2, and the limiting component can move in the direction away from the opening of the groove 3 when subjected to pressure. When the city is in a rainstorm and there is a high level of water accumulation on the road surface, the position of the manhole cover is easily invisible due to the water accumulation. At this time, it will become difficult for municipal maintenance personnel to find the manhole cover and move it away to speed up the discharge of the accumulated water. This product is provided with a pressure-triggered limiting component. When there is a lot of water on the road surface, the limiting component begins to move in the direction away from the opening of the groove 3 due to the large water pressure. When the limiting component moves a certain distance, the warning component located in the groove 3 begins to move outside the manhole cover under the buoyancy of the water, and finally floats on the water surface and can be observed by people, thereby playing a warning and reminder effect.

[0021] For example Figure 2 , Figure 3 As shown, the warning component includes a warning ball 5, which is movably installed in the groove 3 and connected to the groove 3 through a connecting line 10. When the limit component is pressed down by the pressure of water, the groove 3 begins to communicate with the drainage groove 2. At this time, the accumulated water enters the drainage groove 2 and the groove 3. The warning ball 5 is made of a plastic material with a low density and floats out under the buoyancy of the water. Due to the connection relationship of the connecting rope, the warning ball 5 will not float away with the water flow, but will always remain near the manhole cover body 1 to play a warning role. At the same time, the warning component also includes a box 8 and a spring 7. The box 8 and the groove 3 sliding connection, the warning ball 5 is specifically placed in the box 8 and movably connected to the box 8 through the connecting line 10, the two ends of the spring 27 are fixedly connected to the box 8 and the groove 3 respectively, because the spring 27 is arranged between the box 8 and the groove 3, therefore, under the support of the spring 27, the box 8 will always be near the opening of the groove 3, when the road surface water begins to increase, once the limit assembly leaves the opening of the groove 3, the spring 27 will push the box 8 out of the groove 3 so that the warning ball 5 floats out faster, thereby improving the response speed and avoiding the situation where the warning ball 5 is accidentally stuck in the groove 3.

[0022] The limiting assembly of this product includes a slider 4 and a spring 6. The slider 4 is movably installed in the drainage groove 2. The two ends of the spring 6 are fixedly connected to the slider 4 and the drainage groove 2 respectively. Figure 2 and Figure 3 As shown, there are gaps on both sides of the slider 4 and the drainage groove 2, and the gaps can prevent the slider 4 from generating friction with the inner wall of the drainage groove 2, so that when the slider 4 is subjected to pressure, it can move downward stably. When the slider 4 moves to completely leave the opening of the groove 3, the warning ball 5 in the groove 3 will be pushed out and float out of the water due to the buoyancy of the water.

[0023] The drainage groove 2 and the groove 3 of the product are both provided with a water guide groove 9 connected to the outside. After the water on the road surface recedes, the water guide groove 9 can discharge the accumulated water in the groove in time.

[0024] Finally, the warning ball 5 is coated with a reflective coating, which can reflect the light of vehicles or flashlights at night, making it easier for staff to find the manhole cover.
