Embodiment Construction

[0031] The water in the magnetically controlled water bucket of the waterproof manhole cover reaches a certain level, let the horizontal plate (5) take the connection hole between the horizontal plate (5) and the connecting plate (4) as the fulcrum, and use the force-saving effect of the lever of the horizontal plate to pass through the center The ball post (3) jacks up the pressure control well cover.

[0032] The bottom of the magnetically controlled water bucket (7) has an annular disc, one, when the water in the magnetically controlled water bucket (7) is relatively small, under the action of 3 permanent magnets (8), the annular disc and the stopper (9) Mutual attraction, thereby, the water in the magnetic control water bucket (7) inside is blocked in the inside; Two, when the water in the magnetic control water bucket (7) inside reaches a certain degree, has reached the state of claim 2: the pressure control well cover is jacked up Three, when the water in the magneticall...

Abstract

In a rain season, rainwater often floods roads, i.e. waterlogged highways are formed, and if waterlogging occurs in a street, a waterlogged street is formed. Traffic jam is formed by waterlogging, serious inconvenience is caused to the traffic of various kinds of vehicles and pedestrians, and electric shock accidents can be caused by waterlogging. The invention relates to an anti-waterlogging manhole cover, which effectively solves the problem. The anti-waterlogging manhole cover is composed of an outer frame bracket, a voltage-controlled manhole cover, a central ball column, a connecting plate, a barrel connecting plate, a transverse plate, a magnetic control bucket, a permanent magnet, a washer, a washer spring and the like. Leaves and the like can be blocked above, and fine sands can beshaken to flow, so that water flow is prevented from being blocked by the fine sands.

Description

technical field [0001] The invention relates to the field of traffic engineering, in particular to a waterproof manhole cover. Background technique [0002] 1. During the heavy rain season, the roads are often flooded with rainwater, which is the so-called flooded road. If the flooding occurs on the main street, it is called a "flooded street". Flooding causes serious traffic congestion, brings serious inconvenience to traffic of various vehicles and pedestrians, and flooding can also cause electric shock accidents. [0003] 2. Search for "waterproof immersion manhole cover", there is a similar patent: [0004] A reinforced waterproof manhole cover has the right to [0005] Application number: 201721454777.0 Application date: 2017-11-03 [0006] The utility model can enhance the compressive and rolling resistance of the manhole cover, is convenient for installation and maintenance, and has no special function of waterproofing and immersion. [0007] Three, query "waterpr...
