Description

Technical Field

[0001] This utility model relates to the field of municipal manhole cover technology, and in particular to a manhole cover that automatically opens to prevent flooding. Background Technology

[0002] Municipal manhole covers are covers installed in public places such as urban roads and squares to facilitate the maintenance of road facilities. They are mainly used to cover the drainage pipes, cables, and ventilation ducts underneath to protect their normal operation.

[0003] Existing manhole covers have low drainage capacity, which may cause urban flooding in low-lying areas during periods of heavy rainfall due to untimely drainage. In such cases, workers need to open the manhole covers, which is quite troublesome. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a flood-proof, automatically opening manhole cover.

[0005] Technical solution: A flood-resistant, automatically opening manhole cover includes an installation cylinder, an A-shaped structure, and a cover plate. The cover plate is snapped onto the top of the installation cylinder, and two water inlet holes are provided on the cover plate. The cover also includes an activation mechanism and a drainage mechanism. The activation mechanism is provided on the inner wall of the installation cylinder, and the drainage mechanism is also provided on the inner wall of the installation cylinder to increase road drainage. The activation mechanism is used to activate the drainage mechanism.

[0006] As an improvement to the above solution, the starting mechanism includes a mounting base, a slider, a water receiving tube, a return spring, a start button, a squeezing block, a protective shell, and a battery. The mounting base is fixedly connected to the inner wall of the mounting tube, and the slider is slidably connected to the mounting base. The water receiving tube is fixedly connected to the top of the slider, and a drain hole is opened on the lower side of the side wall of the water receiving tube. A return spring is connected between the water receiving tube and the mounting base. A start button is set on the top of the mounting tube, and a squeezing block is fixedly connected to the lower side wall of the water receiving tube. A protective shell is fixedly connected to the inner wall of the mounting tube, and a battery is installed in the protective shell.

[0007] As an improvement to the above scheme, the drainage mechanism includes a fixed base, a crossbeam, a screw, a motor A, a fixed column, a mounting plate, a perforated cylinder, a photovoltaic panel, a sealing cover, a motor B, a gear, and a gear ring. Fixed bases are symmetrically fixed to the inner wall of the mounting cylinder. A crossbeam is slidably connected between two fixed bases. A screw is rotatably connected between the upper and lower parts of both fixed bases. Motor A is mounted on the top of each of the two fixed bases. The output shaft ends of both motors A are fixedly connected to the upper ends of adjacent screws. Fixed columns are symmetrically fixed to the top of the crossbeam. Mounting plates are fixedly connected to the top of each of the two fixed columns. Perforated cylinders are rotatably connected to the periphery of each of the two mounting plates. Photovoltaic panels are mounted on the top of each of the two mounting plates. Sealing covers are threaded onto the tops of both perforated cylinders. Motor B is mounted in the middle of the top of the crossbeam. A gear is fixedly connected to the output shaft end of motor B. Gear rings are fixedly connected to the lower side of the outer wall of each of the two perforated cylinders, and both gear rings mesh with the gears.

[0008] As an improvement to the above solution, both sealing caps are made of PC material.

[0009] As an improvement to the above solution, a rubber pad is also included, with a rubber pad provided on the side wall where the protective shell fits into the mounting cylinder.

[0010] As an improvement to the above solution, a ring-shaped light strip is also included, with a ring-shaped light strip embedded in the upper inner wall of both sealing covers.

[0011] The beneficial effects achieved by this utility model are as follows: 1. In rainy weather, the porous cylinder automatically rises to the upper part of the cover plate with the assistance of the starting mechanism, thereby increasing the drainage capacity of the road surface and effectively preventing waterlogging. At the same time, the motor B drives the porous cylinder to rotate, which can prevent debris that comes with the water flow from clogging the porous cylinder. By setting up photovoltaic panels and batteries, solar energy can be converted into electrical energy and stored when the weather is good, without the need for an external power source.

[0012] 2. By setting rubber pads, rainwater can be prevented from entering the protective casing and damaging the battery.

[0013] 3. By setting up a ring-shaped light strip, the light strip can serve as a warning to pedestrians or vehicles, preventing them from colliding with the porous cylinder and causing damage. Attached Figure Description

The water receiving tube 33 is welded and fixed to the top of the slider 32. A drain hole is opened on the lower side wall of the water receiving tube 33. A return spring 34 is connected between the water receiving tube 33 and the mounting base 31. The start button 35 is set on the top of the mounting tube 1. The start button 35 has been waterproofed and can be used normally in an environment with sufficient moisture. The pressing block 36 is welded and fixed to the lower side wall of the water receiving tube 33. The pressing block 36 is located directly above the start button 33. The protective shell 37 is fixed to the inner wall of the mounting tube 1 by bolts. The battery 38 is installed in the protective shell 37 and is electrically connected to the start button 33.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, the drainage mechanism includes a fixed base 41, a crossbeam 42, a screw 43, a motor A44, a fixed column 45, a mounting plate 46, a perforated cylinder 47, a photovoltaic panel 48, a sealing cover 49, a motor B410, a gear 411, and a gear ring 412. Fixed bases 41 are symmetrically welded and fixed to the inner wall of the mounting cylinder 1. A crossbeam 42 is slidably connected between two fixed bases 41. A screw 43 is rotatably connected between the upper and lower parts of each of the two fixed bases 41. Motors A44 are bolted to the top of each of the two fixed bases 41. The output shaft ends of each of the two motors A44 are fixedly connected to the upper end of the adjacent screw 43. Fixed columns 45 are symmetrically welded and fixed to the top of the crossbeam 42. Mounting plates are bolted to the top of each of the two fixed columns 45. 46. ​​Both mounting plates 46 are rotatably connected to perforated cylinders 47. Photovoltaic panels 48 are mounted on the top of both mounting plates 46. Sealing caps 49 are threadedly connected to the top of both perforated cylinders 47. Both sealing caps 49 are made of PC material, i.e., polycarbonate, a high-performance polymer material with high strength, high toughness, excellent impact resistance, high temperature resistance, and high transparency. Motor B410 is bolted to the middle of the top of the crossbeam 42. Gear 411 is fixedly connected to the end of the output shaft of motor B410. Gear rings 412 are fixedly connected to the lower side of the outer wall of both perforated cylinders 47, and both gear rings 412 mesh with gear 411. Motors A and B are electrically connected to the start button 35.

[0024] In this embodiment, the mounting cylinder 1 is first installed at the opening of the municipal storm drain, and then the cover plate 2 is snapped onto the top of the mounting cylinder 1. During heavy rain, rainwater falls from the inlet hole 21 through the cover plate 2 into the receiving cylinder 33. When the amount of rainwater discharged from the drain hole in the receiving cylinder 33 is less than the amount entering from the inlet hole 21, the weight of the receiving cylinder 33 gradually increases. Under the action of gravity, the receiving cylinder 33 gradually moves downward and the return spring 34 gradually compresses. When the squeezing block 36 follows the receiving cylinder 33... When the start button 35 is pressed and moved downwards, motor A44 starts and drives screw 43 to rotate, thereby moving crossbeam 42 upwards. This ultimately lifts the two perforated cylinders 47 onto the top of cover plate 2, allowing water from the road surface to flow into the storm drain through the perforated cylinders 47. This automatic upward movement of the perforated cylinders 47 during heavy rain increases the drainage speed and effectively prevents flooding. When start button 35 is pressed, motor B410 starts synchronously. Motor B410, through gear 411 and gear... The engagement of ring 412 causes the two porous cylinders 47 to rotate. When debris on the road surface collides with the flowing water and hits the porous cylinders 47, the rotating cylinders 47 can throw the debris away, thus preventing the debris from clogging the porous cylinders 47 and reducing their drainage capacity. When the rain stops, the rainwater in the water receiving cylinder 33 is discharged from the drainage hole, and the weight of the water receiving cylinder 33 gradually decreases. Under the reset action of the return spring 34, the water receiving cylinder 33 is pushed upward and reset, and the squeezing block 36 is formed. When the start button 35 is pressed, motor B410 is turned off, while motor A44 reverses and drives the porous cylinder 47 to move downwards and reset via screw 43 and crossbeam 42. Under normal sunny weather, sunlight shines through the sealing cover 49 onto the photovoltaic panel 48, which converts solar energy into electrical energy and stores it in battery 38. Thus, no external power supply is needed to drive motors A44 and B410. Even if the city experiences a power outage, motors A44 and B410 can start and work normally.

[0025] like Figure 4 As shown, it also includes a rubber pad 6, and the protective shell 37 is provided with a rubber pad 6 on the side wall that fits against the mounting cylinder 1.

[0026] By setting the rubber gasket 6, the sealing of the connection between the protective shell 6 and the mounting cylinder 1 is ensured, which can prevent rainwater from entering the protective shell and damaging the battery.

[0027] like Figure 5 As shown, it also includes a ring light strip 7. The ring light strip 7 is embedded in the upper inner wall of both sealing covers 49. The ring light strip 7 is electrically connected to the start button 35.

[0028] When motors A and B start, the ring light strip 7 also starts simultaneously. At night, the ring light strip 7 emits light, which can serve as a warning to pedestrians or vehicles, preventing them from colliding with the porous cylinder 47 and causing damage.
