Problems solved by technology

These two types of well covers have their own characteristics. The rain grate is designed in the shape of a rectangular parallelepiped fishbone, which is convenient for collecting rainwater and sewage. However, due to its open design, the unavoidable odor in the drainage ditch diffuses from the rain grate, which affects the environment; The cast iron manhole cover ca

Example Embodiment

[0026] Example 1:

[0027] Attached Figure 1-3 As shown, a wellhead drainage device with a vane-type closing valve includes an upper shell and a lower shell 6 that are fixedly connected, and a flat ring-shaped closing valve. The lower shell 6 is in the shape of a basin and has a middle part of the basin bottom. The upper shell includes an inner tube 12 and an upper edge 1 for fixing on the ground. An annular cavity is formed between the inner tube 12 and the lower shell 6, and the outer wall of the inner tube 12 is sleeved. A push ring 8 is connected with a plurality of plastic blocks 9 fixed on the push ring 8; a cross mounting bracket 5 is fixed on the inner wall of the inner cylinder 12, and a hub fixing post 4 is fixedly arranged at the center of the cross mounting bracket 5 A hub 3 is installed on the top of the hub fixing column 4, the center of the hub 3, the inner cylinder 12, and the closing valve are on the same axis perpendicular to the hub plane, and the side of the...

Example Embodiment

[0033] Example 2:

[0034] On the basis of Example 1, combined with image 3 As shown, the end of the mounting post of the narrow end of the blade 14 is sleeved with a return spring 13, one end of the return spring 13 is fixedly connected to the mounting post of the narrow end of the blade 14 and the other end is fixedly connected to the hub 3. The inner wall of the hole used to accommodate the mounting column.

[0035] When the drainage is over, there is no more water in the water inlet on the inner cylinder 12, the water in the annular cavity is gradually discharged from the circular hole at the bottom of the lower shell 6, and the annular cavity is The water level gradually decreases, and the buoyancy of the plastic block 9 decreases. Under the action of gravity, the plastic block 9 and the push ring 8 fall, pull the push-pull rod 10, rotate the rocker arm 11, and return The position spring 13 twists the blade 14 back. Under the dual action of the push ring 8 and the return spr...

Abstract

The invention discloses a wellhead drainage device with a vane type closed valve, which comprises an upper casing and a lower casing fixedly connected, an annular cavity is formed between the inner cylinder of the upper casing and the lower casing , the outer wall of the inner cylinder is sleeved with a push ring, and a plurality of plastic blocks are fixed on the push ring; a hub is installed in the middle of the inner cylinder, and a plurality of rotatable blades are installed on the hub, and the blades The wide end of the blade is hinged on the inner cylinder through a mounting column, the end of the mounting column at the wide end of the blade is fixed with a rocker arm, the end of the rocker arm is fixedly connected with a push-pull rod, and the other end of the push-pull rod is hinged on the On the push ring, the top of the inner cylinder is provided with a strip-shaped water inlet, and the bottom of the lower shell is provided with a circular hole-shaped water outlet, and the water inlet of the water inlet is more than ten times the water outlet of the water outlet . The invention utilizes the closed valve which can be opened and closed automatically, and takes water permeability and environmental protection into account.

Description

technical field [0001] The invention relates to the field of drainage well equipment, in particular to a wellhead switch device for a drainage well, in particular to a wellhead drainage device with a blade-type closed valve. Background technique [0002] With the continuous development of urban construction in our country, the role of cities has become more and more important. As an important part of urban functions, urban drainage systems play an important role in ensuring the normal life of residents. It is an indispensable part of residents' lives. An important part of. With the development of urbanization in our country, a large number of people are pouring into the city, and the urban drainage system is under a huge test. In recent years, with the occurrence of heavy rainfall, urban waterlogging has become more and more serious. In the existing drainage system, there are mostly two kinds of drainage well covers commonly used, one is a solid cast iron well cover, and th...
