Embodiment Construction

[0014] Such as figure 1 , figure 2 Shown:

[0015] The present invention is made up of shaft 1 and flap 2.

[0016] Shaft 1 is made up of well bottom 3, well wall 4, well cover 5, front tooth ridge 6, rear tooth ridge 7, water inlet 8, water outlet pipe 9, shut-off pipe 10. Bottom 3 adopts concrete, bricks to form a horizontal plane, and well wall 4 adopts concrete, bricks to form an upright wall, or adopts other materials such as plastics to make; The tooth ridge 6 and the rear tooth ridge 7 are a small platform protruding horizontally from the well wall 4, one left and one right respectively, and are located on the opposite sides of the well wall 4. The water inlet pipe 8 is arranged on the well wall above the front tooth ridge 6, the water outlet pipe 9 is arranged on the well wall above the rear tooth ridge 7, and the intercepting pipe 10 is arranged on the other side of the well wall 4, located at the front tooth ridge 6 and the rear tooth ridge. 7 below.

Abstract

The invention relates to a turning plate type preliminary rainwater intercepting well. The structure of the turning plate type preliminary rainwater intercepting well comprises a vertical well and a turning plate, wherein the turning plate can rotate around a connecting shaft, the two ends of the shaft are connected to the well wall of the vertical well, a shaft sleeve is sheathed on the shaft, a panel is fixed on the shaft sleeve, the panel is divided into a left half part and a right half part, the left half part is watertight, a counterweight and a float are fixedly arranged below the left half part, the right half part comprises a water passing gap communicated with a water storage tank, a water leaking hole is formed at the bottom of the water storage tank, the turning plate is arranged below a water inlet pipe and a water outlet pipe and above an intercepting pipe, and front tenons and back tenons on two opposite sides on the well wall are arranged in the positions in the rotation direction of the turning plate. The turning plate type preliminary rainwater intercepting well disclosed by the invention can solve the respective defects of a leaping weir type intercepting well, an overflow weir type intercepting well and an intercepting groove type intercepting well. The turning plate type preliminary rainwater intercepting well disclosed by the invention has the advantages of automatically intercepting all high-concentration rainwater during the preliminary stage of rainfall, draining all clean rainwater during the medium-late stage of the rainfall and realizing diversion of the clean rainwater and the dirty rainwater; and furthermore, the structure is simple, no automatic control element and no energy power are required, automatic operation is realized, and the management is simple.

Description

technical field [0001] The invention relates to a rainwater pipeline interception device, in particular to a flap type initial rainwater interception well. Background technique [0002] A very important method of rainwater pollution control is to intercept the high-concentration rainwater at the beginning of the rainfall, divert it to the adjacent sewage pipe or reservoir, and then transport it to the sewage treatment plant for treatment, and discharge the clean rainwater directly into the river in the middle and late stages of the rainfall . The rainfall intensity of a rain and its water flow and concentration in the drainage pipes change with time. The intensity of the rainfall is small at the beginning, then gradually increases until the highest intensity, and then gradually decreases until the rain stops. The amount of water in the initial stage of rainfall is small, and the ground pollution is first washed away. Therefore, the concentration of pollutants in the rainwat...
