[0026] [First Embodiment]

[0027] As Figures 1 - 3 shown in the figure, an automatic opening and closing vertical grate provided by the first embodiment of the present utility model includes a grate surface 1. A plurality of through-flow holes are opened inside the grate surface 1 so that during daily urban drainage, drainage is achieved through the through-flow holes of the vertical grates provided on both sides of the road, and large particle impurities are prevented from entering the inside of the drainage pipe by the grate surface 1. The grate surface 1 is hinged to the base 2 through a first rotating shaft 3. The base 2 is fixed inside the drainage channel A. The grate surface 1 can rotate around the first rotating shaft 3, thereby realizing the opening and closing actions of the grate surface 1, and further meeting the drainage requirements of urban roads in different situations through the opening and closing process of the grate surface.

[0028] As Figure 1As shown, in this embodiment, the bottom end of the grating surface 1 is hinged to the base 2, and the top end of the grating surface 1 is connected to the pulling rope L. This enables the grating surface 1 to rotate counterclockwise around the first rotating shaft 3 to open the grating surface 1, so that when heavy rainfall occurs in the city, large-capacity drainage can be achieved in a timely manner through the opening of the grating surface. At the same time, the grating surface 1 can rotate clockwise around the first rotating shaft 3 to close the grating surface 1, so that drainage can be achieved through the internal flow holes of the closed grating surface. The grating surface 1 prevents large particulate impurities from entering the inside of the drainage pipeline, meeting the drainage requirements of urban roads under different conditions.

[0029] As a further preference of this embodiment, an elastic member 4 is sleeved on the outer periphery of the first rotating shaft 3. The elastic member 4 can be a torsion spring commonly used in the mechanical field, etc. One end of the elastic member is fixedly connected to the grating surface 1, and the other end is fixedly connected to the base 2. By providing the elastic member 4, it can help the grating surface 1 to achieve the closing and reset process after the grating surface 1 is opened.

[0030] As Figure 1 shown, a bracket 6 is fixedly installed inside the overflow well B. The float 9 is hinged to one end of the bracket 6 through the second rotating shaft 7. In this embodiment, the float 9 is set as a sphere to evenly bear the buoyancy of the water body. According to actual usage requirements, the float 9 can also be set in other required shapes. A fixed pulley 5 is fixedly installed at the top of the overflow well B. One end of the pulling rope L is fixedly connected to the float 9, and the other end is wound around the outer periphery of the fixed pulley 5 and then connected to the grating surface 1. To further extend the service life of the pulling rope L, it is preferred to make the pulling rope L of a waterproof material.

[0031] As Figure 1 shown, a rope threading device 8 is also movably sleeved on the outer periphery of the second rotating shaft 7. The rope threading device 8 is fixedly connected to the float 9. Through the rope threading device 8, it is convenient to fixedly connect one end of the pulling rope L to the float 9.

[0032] As a preferred implementation mode of this embodiment, an overflow pipe C is communicated with one side of the overflow well B. The rope threading device 8 is arranged close to the overflow pipe C, and the float 9 is arranged away from the overflow pipe C to reduce the damage and lifting failure of the float 9 caused by water flow impact.

[0033] At the same time, in this embodiment, the gravity of the float 9 needs to be greater than the gravity of the rope threading device 8. The float 9 can rotate counterclockwise around the second rotating shaft 7 under the action of buoyancy, and rotate clockwise around the second rotating shaft 7 to return to its original position due to its own gravity after the buoyancy disappears.

[0034] The specific working process of this embodiment is as follows:

[0035] During the daily drainage of the city, the accumulated water on both sides of the road is drained through the flow holes of the vertical grating surface through the drainage channel A. At the same time, large particulate impurities can be prevented from entering the drainage pipeline. At this time, the vertical grating structure is as Figure 1 shown;

[0036] When heavy rainfall occurs in the city and the accumulated water inside the overflow well B reaches a certain depth, the floating body 9 floats upward under buoyancy and deflects counterclockwise around the second rotating shaft 7, driving the rope threading device 8 to tighten the pulling rope L. Under the dual action of the water flow impact force and this pulling force, the grating surface 1 is dragged to rotate counterclockwise around the first rotating shaft 3 to open. At this time, the vertical grating structure is as Figure 2 shown;

[0037] When the rainfall ends and the water level in the overflow well B is emptied from the overflow well C to a certain height position, the buoyancy decreases or disappears, and the vertical grating surface 1 is reset and closed again under the elastic restoring force of the torsion spring. At this time, the vertical grating structure returns to Figure 1 shown.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
