Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a municipal drainage well, the inside including vertical setting is the well body 1 of cavity cube form, and the open-top of well body 1 is provided with well lid 2 horizontally. The well lid 2 is a hollow structure. A hanging basket 21 is arranged below the well lid 2.

The side wall of the bottom end of the well body 1 is horizontally provided with a drainage pipeline 3, and the drainage pipeline 3 is communicated with the inside of the well body 1. The position in the well body 1 above the drainage pipeline 3 is horizontally provided with a limiting table 5, and the shape of the limiting table 5 is matched with that of the well body 1. The vertical side walls of the limiting table 5 are fixedly connected with the well body 1. The middle position of the limit table 5 is provided with a circulation hole 51 vertically penetrating through the limit table 5. A fixing column 6 is vertically arranged between the circulation hole 51 and the bottom surface of the well body 1. The bottom end of the fixing column 6 is fixedly connected with the well body 1 integrally, and the top end is exposed above the circulation hole 51. The position of the fixed column 6 below the circulating hole 51 is sleeved with a spherical buoyancy block 7. The buoyancy block 7 is a solid body made of rubber. The buoyancy block 7 is connected with the fixed column 6 in a sliding way. The flow hole 51 has a truncated cone shape with a small upper part and a large lower part. The maximum cross-sectional area of the buoyancy block 7 is larger than the cross-sectional area of the top end of the circulation hole 51, so that the buoyancy block 7 cannot pass through the circulation hole 51 to reach the upper part of the limit table 5. Because the buoyancy block 7 is a sphere, the fitting degree with the flow hole 51 is better, and the plugging degree of the buoyancy block 7 to the flow hole 51 is higher.

A horizontal emergency pipeline 4 is arranged on the side wall of the well body 1 opposite to the side wall provided with the drainage pipeline 3, and the emergency pipeline 4 is communicated with the inside of the well body 1. The communication port of the emergency pipeline 4 and the well body 1 is positioned between the hanging basket 21 at the top end of the well body 1 and the limiting platform 5.

When raining, rainwater enters from the well cover 2 and then reaches the bottom end of the well body 1 through the circulation holes 51, and then is discharged through the drainage pipeline 3. When the drainage pipeline 3 flows backwards, water is gradually gathered at the bottom of the well body 1, and the water level gradually rises. The buoyancy block 7 sleeved on the fixed column 6 rises under the action of buoyancy, and finally the circulation hole 51 is blocked by the buoyancy block 7, so that rainwater on the buoyancy block is gathered above the limiting platform 5, and water on the buoyancy block cannot continuously circulate upwards. After the surface of water of rainwater reachs emergency pipeline 4, the rainwater is discharged from emergency pipeline 4. The emergency pipeline 4 is communicated with a water storage device. Through the arrangement, the problem that the surface water cannot be continuously discharged downwards due to the fact that the well body 1 is sealed after flowing backwards is avoided.

Referring to fig. 2 and 3, a groove which is arranged at an upper interval and a lower interval and surrounds the well body 1 is horizontally formed on the side wall of the top end of the well body 1, a well cover platform 11 is formed at the groove bottom of the upper groove, and a hanging basket platform 12 is formed at the groove bottom of the lower groove. The shape of well lid 1 matches with the shape of well lid platform 11, and well lid 1 is placed in well lid platform 11. The manhole cover 1 is fixed on the manhole cover stand 11 by a first fixing bolt 22. Hang basket platform 12 and be provided with the basket 21 of hanging of inside cavity and being the form of falling four-edged terrace, hang and be provided with a plurality of through-holes and top opening on the basket 21. The side wall at the top end of the hanging basket 21 is provided with a hem extending outwards, and the hem is abutted against the hanging basket table 12. The cradle 21 is fixed to the cradle table 12 by the second fixing bolt 23, and the cradle 21 is stabilized. The hanging basket 21 can prevent sundries in the rainwater from falling into the well body 1 and has a falling prevention function.

The implementation principle of the embodiment is as follows: when the water level of the drainage pipeline 3 rises due to large rainfall or large road surface drainage amount, water rises from the bottom end of the well body 1, the buoyancy block 7 floats upwards along with the rising water level, and as the diameter of the buoyancy block 7 is larger than the aperture of the circulation hole 51, the buoyancy block 7 is clamped when rising to the circulation hole 51, the rising direction of the water flow is effectively blocked, and the situations that sewage flows backwards and pollutes the road surface are avoided; the water flowing down from the well lid 2 is continuously discharged through the emergency pipeline 4, so that the problem that the accumulated water on the road surface cannot be discharged due to the closed drainage pipeline 3 is prevented

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
