Embodiment 1

[0026] Such as Figure 1 to Figure 3 As shown, a large-flow anti-clogging manhole cover includes an outer shell 14 fixedly connected to the inner wall of the sewer and a cover plate 13 arranged on the top of the outer shell 14, and several cover components are slidably arranged on the cover plate 13. The outer casing 14 includes a cavity 1 inside, and a control part connected with the cover assembly is arranged in the cavity 1, and the control part controls the cover assembly according to the amount of accumulated water in the cavity 1. The degree of movement on the cover plate 13 changes the amount of water entering the cover plate 13 .

[0027] The control part includes a hollow trapezoidal buoy 2, the bottom of the buoy 2 does not fit the cavity 1, the top is fixedly connected to the pole 7, and the bottom of the buoy 2 does not fit the cavity 1 for the purpose of Reserve enough space to prevent the bottom of the buoy 2 from being too tight with the cavity 1, resulting in ...

Embodiment 2

[0031] Such as figure 1 , figure 2 , Figure 4 and Figure 5 As shown, a large-flow anti-clogging manhole cover includes an outer shell 14 fixedly connected to the inner wall of the sewer and a cover plate 13 arranged on the top of the outer shell 14, and several cover components are slidably arranged on the cover plate 13. The outer casing 14 includes a cavity 1 inside, and a control part connected with the cover assembly is arranged in the cavity 1, and the control part controls the cover assembly according to the amount of accumulated water in the cavity 1. The degree of movement on the cover plate 13 changes the amount of water entering the cover plate 13 .

[0032] In this embodiment, the cover assembly includes a "T"-shaped strut 7 that runs through the cover plate 13, and the bottom of the strut 7 is provided with a limit plate 12. The interior of the strut 7 is hollow and the bottom is sleeved with Sliding rod 11, the bottom of the limiting plate 12 is provided wi...

Embodiment 3

[0037] Such as figure 1 , figure 2 and Figure 6 As shown, a large-flow anti-clogging manhole cover includes an outer shell 14 fixedly connected to the inner wall of the sewer and a cover plate 13 arranged on the top of the outer shell 14, and several cover components are slidably arranged on the cover plate 13. The outer casing 14 includes a cavity 1 inside, and a control part connected with the cover assembly is arranged in the cavity 1, and the control part controls the cover assembly according to the amount of accumulated water in the cavity 1. The degree of movement on the cover plate 13 changes the amount of water entering the cover plate 13 .

[0038] The cover plate 13 is provided with a first water inlet 9 and a second water inlet 8 sleeved on the outside of the pole 7. The first water inlet 9 is mainly used for drainage when the rainfall is small, and the flowing water passes through the first water inlet. The water outlet 9 enters the cavity 1, and is discharged...

Abstract

The invention discloses a large-flow anti-blocking inspection well cover. The large-flow anti-blocking inspection well cover comprises an outer shell fixedly connected with the inner wall of a sewer and a cover plate arranged at the top of the outer shell, a plurality of sealing cover assemblies are arranged on the cover plate in a sliding mode, a cavity is formed in the outer shell, a control part connected with the sealing cover assemblies is arranged in the cavity, and the control part controls the moving degree of the sealing cover assemblies on the cover plate according to the amount of accumulated water in the cavity so as to change the water inlet amount of the cover plate. The inspection well cover can automatically adjust the extending height of the sealing cover assemblies according to the amount of accumulated water in the inspection well cover under the condition of large-flow rainwater in rainy days, therefore, the water discharge amount of the inspection well cover is increased, and the influence on traffic and public safety caused by excessive accumulated water on a road is avoided.

Description

technical field [0001] The invention relates to the technical field of water flow control, in particular to a large-flow anti-clogging inspection well cover. Background technique: [0002] The inspection well cover that uses in the city at present all adopts a heavy iron plate or steel plate to make, is connected with the crossing of the sewer by rotating or covering, and only a few apertures are set on the cover plate of the inspection well cover. And these apertures can also be used when the amount of rainwater is small, but once the rainfall is too large, the amount of accumulated water on the road surface will cause poor drainage than the drainage of the aperture of the manhole cover. And if the manhole cover is picked up in order to increase drainage, it may cause pedestrians to fall into the sewer and be dangerous. Therefore need a kind of inspection shaft cover that can change the inspection shaft cover water inlet according to the amount of displacement, can also gu...
