Description

Technical Field

[0001] This utility model relates to the field of manhole covers, and in particular to a safety drainage manhole cover. Background Technology

[0002] During urban construction, dedicated drainage ditches are installed and covered with steel mesh as filters to block debris such as tree branches and plastic bags, preventing blockages. However, in urban life, rainwater can easily accumulate on the roads during rain. To speed up drainage, manhole covers are often lifted and placed on the roadside. However, due to neglect or forgetting to replace the covers after drainage, the manholes are left exposed on the road surface. Pedestrians or vehicles may fall into or get stuck in the manholes without noticing, especially at night, when accidents are more likely to occur.

[0003] In the prior art, such as Chinese patent CN078748U, a drainage well cover structure is disclosed, including a cover base and a cover plate. The cover plate is placed on the cover base, and through holes for water flow are distributed on the cover plate. The characteristic is that an annular stepped ring is protruding on the inner wall of the cover base, and the cover plate is composed of two plates that are movably connected together. When the cover plate is placed on the cover base, the cover plate rests on the stepped ring through its periphery, which is adapted to the shape of the stepped ring, and the upper surface of the cover plate is flush with the top surface of the cover base. This drainage well cover structure requires the cover plate to be rotated open during use. Although it can achieve drainage, the cover plate is in a flipped-up state during drainage, which can easily cause pedestrians to trip, especially when a vehicle hits the cover plate, which will cause more serious accidents. Therefore, there is an urgent need for a safe drainage well cover to solve the above problems. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a safety drainage well cover.

[0028] Reference Figures 1 to 3A safety drainage well cover includes a base 10, a top cover 20, several baffles 30, and several reset components 40;

[0029] The base 10 has several first through slots 11 and several mounting slots 12 alternately arranged along its circumference, with the first through slots 11 penetrating the base 10 vertically.

[0030] The top cover 20 is rotatably mounted on the base 10 and has several second through slots 21 arranged at intervals along its circumference, which are opposite to the first through slot 11. The second through slots 21 penetrate the top cover 20 vertically.

[0031] The baffle 30 is installed in the mounting slot 12;

[0032] The reset component 40 is disposed in the mounting groove 12 and its two ends abut against the base 10 and the baffle 30 respectively.

[0033] The second channel 21 can be arranged opposite to the first channel 11 when the top cover 20 is rotated relative to the base 10 to the first position, so that water can flow into the drain pipe through the second channel 21 and the first channel 11; or it can be arranged opposite to the mounting groove 12 when the top cover 20 is rotated relative to the base 10 to the second position, so that at least a portion of the baffle 30 extends into the second channel 21 to close the second channel 21.

[0034] In this invention, when the top cover 20 rotates to the second position relative to the base 10, the second through groove 21 and the mounting groove 12 are arranged opposite each other, so that at least a portion of the baffle 30 extends into the second through groove 21 under the action of the reset member 40, thereby closing the second through groove 21. At this time, the manhole cover is in normal use, and the rotation of the top cover 20 relative to the base 10 is also restricted, preventing accidental activation of the emergency drainage function. When severe water accumulation or flooding occurs, the emergency drainage function of the manhole cover needs to be activated. Specifically, first, the baffle 30 is pressed downward to disengage it from the second through groove 21, and then the top cover 20 is rotated to allow the top cover to... The lower end face of the top cover 20 abuts against the upper end face of the baffle 30 until it rotates to the first position relative to the base 10. At this time, the second through groove 21 and the first through groove 11 are arranged opposite each other, so that the water flow above the top cover 20 can flow into the drainage pipe through the second through groove 21 and the first through groove 11 in sequence to realize emergency drainage. The advantage of this utility model is that the structure described above can connect the first through groove and the second through groove by rotating the top cover and the base relative to each other, thereby realizing emergency drainage of the manhole cover. It will not cause safety hazards due to the cover plate being higher than the upper end face of the manhole seat after rotation, and it reduces the difficulty of operation and drainage, and has very good practicality.

[0035] In some embodiments, the base 10 is provided with an annular relief groove 13 with an open upper end, and also includes a connecting ring 50 disposed in the annular relief groove 13, with baffles 30 spaced apart and connected to the connecting ring 50; the connecting ring 50 connects multiple baffles 30 into a whole, so that only one or two baffles 30 need to be pressed to push all baffles 30 to move simultaneously. In order to reduce the force required for pressing, the baffles 30 can be made of lightweight materials.

[0036] In some embodiments, the connecting ring 50 and the baffle 30 are integrally formed.

[0037] In some embodiments, the reset member 40 is configured as a spring.

[0038] In some embodiments, a filter screen 60 is provided in the second channel 21; it can block debris such as branches and plastic bags, and prevent blockage of the second channel 21, the first channel 11 or the drainage pipe.

[0039] In some embodiments, the baffle 30 is provided with a plurality of drainage holes 31; this arrangement allows water accumulated on the upper surface of the baffle 30 to flow into the drainage pipe through the drainage holes 31 even when emergency drainage is not required, thus preventing water accumulation on the baffle 30 from causing odor.

[0040] In some embodiments, a bearing 70 is provided between the top cover 20 and the base 10; this arrangement can reduce the frictional force when the top cover 20 rotates relative to the base 10, making it easier for workers to operate the rotation of the top cover 20.

[0041] In some embodiments, the top cover 20 is provided with an adjustment groove 80; as a preferred embodiment of the adjustment groove 80, the adjustment groove 80 is set as an internal hexagonal groove. Specifically, the worker carries an external hexagonal wrench to connect with and rotate the internal hexagonal groove on the top cover 20, which facilitates the worker's operation of rotating the top cover 20.

[0042] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
