Background
inspection wells, commonly known as inspection wells, are auxiliary structures which are arranged at junctions of drainage pipelines, turning positions, pipe diameter or gradient changing positions, water dropping positions or linear pipelines at certain intervals and are convenient for regular inspection and dredging of the pipelines. When the connecting fall of the water inlet and the water outlet pipes of the inspection well is large or the water converging amount is large and the flow speed is high, if the water flow is not decelerated and energy is dissipated, the inspection well body and the bottom of the inspection well can be impacted, scoured and eroded. The energy dissipation is to buffer the water flow with larger potential energy and reduce the damage of the water flow potential energy to the well bottom. Impact and vibration can greatly affect the connection reliability, sealing reliability and service life of the pipeline. At present, the problems of impact, scouring and erosion of water flow to a well body and a well bottom are solved, drop energy dissipation measures of a multi-stage step, a turn-back step and a spiral-flow step are mostly adopted, but due to the fact that the structure is complex, the inspection well cannot achieve the purpose of inspecting and dredging pipelines, and the effect and the significance of regular inspection and dredging of the inspection well are lost.

Drawings
FIG. 1 is a cross-sectional view of the present invention;
In the figure: 1-closing well body, 2-energy separation well body, 3-water inlet, 4-vertical wall well body, 5-water outlet, 6-buffer pad, 7-sealing ring, 8-spring, 9-spring seat I, 10-spring seat II, 11-exhaust valve and 12-base reinforcing rib.
Detailed Description
The invention is further described with reference to the following drawings and detailed description.
Example 1: as shown in figure 1, the drop energy dissipation anti-floating plastic inspection well comprises a closing-in well body 1, a well body 2, a water inlet 3, a vertical wall well body 4, a water outlet 5, a buffer pad 6, a sealing ring 7, a spiral mechanical spring 8, a spring seat I9, a spring seat II 10, an exhaust valve 11 and a base reinforcing rib 12.
The well body 1 adopts integrated into one piece, and the well body 2 adopts integrated into one piece, is connected with the well body 1 through welding, and the water inlet 3 is connected with the well body 2 through welding. The vertical wall well body 4 is integrally formed and welded with the well body 2 through welding. The water outlet 5 is welded with the vertical wall well body 4, the buffer pad 6 and the vertical wall well body 4 form dynamic seal in a sliding fit mode, and the sealing ring 7 is arranged in the buffer pad 6. The spiral mechanical spring 8 is arranged at the bottom of the well body and is fixed through a spring seat I9 and a spring seat II 10. Spring seat I9 is as an organic whole with straight wall well body 4, and spring seat II 10 is as an organic whole with blotter 6, and discharge valve 11 passes through threaded connection with straight wall well body 4 for adjust 6 positions of blotter. The base reinforcing ribs 12 are integrated with the vertical wall well body 4.
The working principle of the invention is as follows: because the height difference exists between the water inlet pipeline port and the water outlet pipeline port, when water flows into the water inlet pipeline port;
(1) When the water flow is small, the potential energy formed by the height difference is small, the water flow falls into a water pool formed by the buffer pad 6 and the well body, and the impact, the scouring and the erosion of the water flow on the buffer pad are reduced through the absorption and energy dissipation of the water body;
(2) when the water flow is large and the flow velocity is high, the water tongue formed by the water flow falls into a water pool formed by the buffer pad 6 and the well body, the impact energy is high, the water body can only partially absorb and dissipate energy, the rest energy directly impacts the buffer pad 6, the buffer pad 6 and the well body slide relatively, the spring is compressed, and the impact kinetic energy of the water flow is absorbed. The greater the water impact energy, the greater the spring compression.
While the present invention has been described in detail with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, and various changes can be made without departing from the spirit and scope of the present invention.
