Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, specifically a protective manhole cover. Background Technology

[0002] Municipal drainage protective manhole covers are devices used to protect the openings of drainage systems, ensuring the safety of the manholes and preventing pedestrians, vehicles, etc. from falling into them. Their main function is to drain water from roads while ensuring the safety and long-term use of the manhole covers.

[0003] Currently, road water is mainly drained into sewers through manhole covers. However, the design of existing manhole covers is relatively simple, usually with only small drainage outlets, resulting in low drainage efficiency. When heavy rainfall causes road water accumulation, a single drainage outlet often cannot drain water quickly and effectively. In addition, the water may contain garbage, which can easily clog the drainage outlets, thus affecting the drainage function of the manhole cover and further reducing the efficiency of road drainage. Utility Model Content

[0004] The purpose of this invention is to provide a protective manhole cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective manhole cover, including a base plate, and further comprising:

[0006] The manhole cover body is rotated on the top of the base plate by a hinge. Drainage outlets are provided on both sides of the surface of the manhole cover body. An adjustment component is provided in the inner cavity of the manhole cover body. The adjustment component includes a torsion block, a rotating rod and an elliptical plate.

[0007] The protective cover is rotated on top of the manhole cover body via a hinge.

[0008] Preferably, the bottom of the torsion block is rotatably connected to the manhole cover body via a bearing, the top of the rotating rod is fixedly connected to the output shaft of the torsion block, and the bottom of the rotating rod is fixedly connected to the elliptical plate.

[0009] Preferably, both sides of the top of the elliptical plate are rotatably connected to movable rods via bearings, and one side of each movable rod is rotatably connected to an adjusting plate, the top of which contacts the drain outlet.

[0010] Preferably, the manhole cover body has sliding grooves on both sides of its bottom, and sliders are fixedly connected to both sides of one end of the two adjusting plates, with the surface of the sliders sliding in the inner cavity of the sliding grooves.

[0011] Preferably, the bottom of the torsion block is rotatably connected to a limiting ring, and the top of the limiting ring is fixedly connected to the bottom of the manhole cover body.

[0012] Preferably, the top of each drain outlet is fixedly connected with a filter screen for intercepting garbage in the accumulated water.

[0013] Preferably, reflective strips for warning vehicles traveling at night are fixedly connected to both sides of the top of the manhole cover body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the setting of the adjustment component, allows for the adjustment of the drainage outlet size to facilitate drainage when there is excessive water accumulation on the road. First, the protective cover is opened via the hinge. Then, the toggle block is turned, causing the rotating rod to rotate. Simultaneously, the rotating rod rotates the elliptical plate. As the elliptical plate rotates, the movable rod rotates and retracts relative to the bearing. Subsequently, the movable rod rotates and moves the adjustment plate relative to the ground. As the adjustment plate moves, the slider moves stably and limitably within the inner cavity of the slide groove. At this time, the drainage outlet is enlarged by the movement of the adjustment plate. Subsequently, the water on the road surface is discharged sequentially through the filter screen into the inner cavity of the sewer. Finally, the filter screen can intercept garbage in the water.

[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] Please see Figures 1-4 As shown, a protective manhole cover includes a base plate 1, and also includes:

[0023] The manhole cover body 2 is rotated on the top of the base plate 1 by a hinge. Drainage outlets 3 are provided on both sides of the surface of the manhole cover body 2. An adjustment component 4 is provided in the inner cavity of the manhole cover body 2. The adjustment component 4 includes a torsion block 401, a rotating rod 402 and an elliptical plate 403.

[0024] The bottom of the torsion block 401 is rotatably connected to the manhole cover body 2 via a bearing. The top of the rotating rod 402 is fixedly connected to the output shaft of the torsion block 401. The bottom of the rotating rod 402 is fixedly connected to the elliptical plate 403. Both sides of the top of the elliptical plate 403 are rotatably connected to movable rods 404 via bearings. One side of the movable rod 404 is rotatably connected to an adjusting plate 405. The top of the adjusting plate 405 contacts the drain outlet 3. Both sides of the bottom of the manhole cover body 2 are provided with sliding grooves 6. Both sides of one end of the two adjusting plates 405 are fixedly connected to sliders 7. The surface of the sliders 7 slides in the inner cavity of the sliding grooves 6. When there is too much water on the road and it is necessary to adjust the size of the drain outlet 3 to facilitate drainage, the protective cover is first opened by the hinge. 5. Then, twist the torsion block 401. The twisting of the torsion block 401 drives the rotating rod 402 to rotate. At the same time as the rotating rod 402 rotates, it drives the elliptical plate 403 to rotate. At the same time as the elliptical plate 403 rotates, it drives the movable rod 404 to rotate and retract relative to each other through the bearing. Then, as the movable rod 404 rotates, it drives the adjusting plate 405 to move relative to each other. At the same time as the adjusting plate 405 moves, it drives the slider 7 to move stably and limit its movement in the inner cavity of the slide groove 6. At this time, the movement of the adjusting plate 405 expands the drain outlet 3. Then, the water on the road surface is discharged into the inner cavity of the sewer through the filter screen 8. Finally, the garbage in the water can be intercepted by the filter screen 8.

[0025] The protective cover 5 is rotated on top of the manhole cover body 2 via a hinge; the bottom of the toggle block 401 is rotatably connected to a limit ring 406, the top of the limit ring 406 is fixedly connected to the bottom of the manhole cover body 2, and the top of the drain outlet 3 is fixedly connected to a filter screen 8 for intercepting garbage in the accumulated water. The two sides of the top of the manhole cover body 2 are fixedly connected to reflective strips 9 for warning vehicles driving at night. The setting of the limit ring 406 can facilitate the stable rotation of the toggle block 401 when it rotates, and can also avoid the phenomenon of damage to the toggle block 401 caused by dust. The setting of the filter screen 8 can facilitate the interception and filtration of garbage in the accumulated water when the accumulated water enters from the drain outlet 3. The setting of the reflective strips 9 can facilitate the warning of people when vehicles are driving at night, and avoid excessive crushing and damage to the manhole cover body 2.

[0026] Working principle: First, the base plate 1 and the manhole cover body 2 are installed at the sewer. Then, the reflective strip 9 is installed to warn pedestrians during nighttime vehicle traffic, preventing damage to the manhole cover body 2 from being run over. When water accumulates on the road, it will drain out through the drain outlet 3 of the manhole cover body 2. Later, when the water accumulation is too high and the size of the drain outlet 3 needs to be adjusted for drainage, first, the protective cover 5 is opened via the hinge, then the toggle block 401 is turned. The turning of the toggle block 401 causes the rotating rod 402 to rotate. As rod 402 rotates, it drives elliptical plate 403 to rotate as well. As elliptical plate 403 rotates, it drives movable rod 404 to rotate and retract relative to it via bearing. As movable rod 404 rotates, it drives adjusting plate 405 to move relative to it. As adjusting plate 405 moves, it drives slider 7 to move stably and limit its movement within the cavity of slide groove 6. At this time, the movement of adjusting plate 405 expands drain outlet 3. Subsequently, the water on the road surface is discharged into the cavity of sewer through filter screen 8. Finally, the garbage in the water can be intercepted by filter screen 8.
