Embodiment
[0019] Such as Figure 1-Figure 5 As shown, a floating ball type initial rainwater interception well includes a well body 1, a cover plate 2 is arranged on the top of the well body 1, a rainwater outlet 3 is arranged on the cover plate 2, and an initial rainwater interception pipe is arranged at the bottom of the well body 1 4 and the rainwater pipe 9, the bottom of the well body 1 is also provided with a slope shaft 5, the inner wall of the well body 1 is provided with a groove 5, the slope shaft 5 is pierced with a movable first floating ball 7, and the slope shaft 5 passes through The center of the first floating ball 7 is convenient for the first floating ball 7 to move along the slope axis 5 without affecting the blocking effect of the first floating ball 7 on the initial rainwater retention pipe 4 and the rainwater pipe 9 . A movable second floating ball 8 is arranged in the groove 5 , and the slope axis 5 is respectively connected with the initial rainwater retention pi...

The invention discloses a floating ball type initial rainwater intercepting well. The floating ball type initial rainwater intercepting well comprises a well body, a cover plate is arranged at the top of the well body, a rainwater opening is formed in the cover plate, an initial rainwater intercepting pipe and a rainwater pipe are arranged at the bottom of the well body, a slope shaft is further arranged at the bottom of the well body, a groove is formed in the inner wall of the well body, a movable first floating ball is arranged on the slope shaft in a penetrating mode, a movable second floating ball is arranged in the groove, the slope shaft is connected with the initial rainwater interception pipe and the rainwater pipe, and the first floating ball and the second floating ball are connected through a connecting rope. According to the floating ball type initial rainwater intercepting well, by means of buoyancy of the first floating ball and the second floating ball in water and displacement caused by interaction between the first floating ball and the second floating ball, initial rainwater can be effectively intercepted, pollution of the initial rainwater to the water environment is reduced, and meanwhile the floating ball type initial rainwater intercepting well has the characteristics of being low in manufacturing cost, easy to construct and low in maintenance cost.
Description
technical field [0001] The invention relates to the technical field of rainwater interception wells, in particular to a floating ball type initial rainwater interception well. Background technique [0002] The initial rainwater is directly discharged into the river through the rainwater pipe, which will cause a certain degree of pollution to the water environment, mainly because the rainwater dissolves a large amount of acid gas in the air, vehicle exhaust, factory exhaust gas and other polluting gases in the early stage of rainfall, and after landing on the ground, Due to the washing of roofs, asphalt concrete roads, etc., the rainwater in the early stage contains a large amount of pollutants, and its pollution level is relatively high, even exceeding the pollution level of ordinary urban sewage. Therefore, whether it is in the combined system or the divergent system, it is of great significance to study how to effectively intercept the initial rainwater and prevent it from...
