The invention belongs to the field of municipal construction, in particular to a pressure-balanced self-dredging basketball well cover, which comprises a basketball well cover body, S-shaped drainage holes are symmetrically arranged on both sides of the basketball well cover body, U-shaped sealing channels with both ends connected to the outside are arranged in the basketball well cover body, and sliding sealing connections are arranged in both openings of the U-shaped sealing channels. A piston block is connected with the piston block. A sealing fluid is filled in the U-shaped sealing passage between the two piston blocks. A connecting rod is fixed at the lower end of the piston block, and an impact plate is fixed at the lower end of the connecting rod. A top rod is fixed at the upper end of the connecting rod far from the upper end of the connecting rod. A through hole is arranged on the side wall of the S-shaped drainage hole. The upper end is arranged through the through hole and extends to the S-shaped drainage hole, and the ejector rod is connected with the through hole by sliding seal. The invention realizes the self-dredging function by setting the ejector rod, impact plate, piston block and U-type sealing passage and cleaning the blocked S-type drainage hole by using water pressure as kinetic energy.

一种压力平衡的自疏通窨井盖
本专利技术属于市政建设领域,尤其是涉及一种压力平衡的自疏通窨井盖。
技术介绍
窨井盖是一种用于道路的常见的排水设施。窨井盖在使用过程中经常会出现堵塞的情况,尤其是在园林景区等,窨井盖的进水口经常会被落叶等杂物堵住,当落叶与进水口贴紧后,由于其叶片厚度薄,与水流的冲击面极小,不易清理,尤其是当窨井盖下方的水流在流动时,叶片的上下方存在一定的压差,使落叶紧紧地附着在进水口,导致窨井盖堵塞的情况。为此,我们提出一种压力平衡的自疏通窨井盖来解决上述问题。
技术实现思路
本专利技术的目的是针对上述问题,提供一种利用水流的压力平衡的自疏通窨井盖。为达到上述目的,本专利技术采用了下列技术方案:一种压力平衡的自疏通窨井盖,包括窨井盖本体,所述窨井盖本体的左右两侧对称设有S型排水孔,所述窨井盖本体内设有两端均与外部连通的U型密封通道,所述U型密封通道的两个开口内均滑动密封连接有活塞块,两个所述活塞块之间的U型密封通道内填充有密封液,所述活塞块的下端固定连接有连接杆,所述连接杆的下端固定连接有冲击板,所述冲击板远离连接杆一侧的上端固定连接有顶杆,所述S型排水孔 ...
