Description

Technical Field

[0001] This utility model relates to the field of negative pressure-free water supply in municipal pipe networks, specifically a negative pressure-free water supply device for municipal pipe networks. Background Technology

[0002] A municipal pipeline network negative pressure-free water supply device is a device directly connected in series with the municipal pipeline network to achieve negative pressure-free water supply. Its core function is to eliminate the influence of negative pressure, ensure water supply stability, and prevent water pollution. In the prior art, a Chinese patent application with application number CN202221593189.6 describes a municipal pipeline network negative pressure-free water supply device. This patent describes a device that uses a forward and reverse motor to drive two take-up rollers to rotate. The two take-up rollers respectively wind up two pull ropes, causing the connecting block to pull the protective door upwards. The protective door then drives two T-shaped sliding bars to slide upwards within two T-shaped grooves, making the protective door easy to open and thus facilitating maintenance by personnel. Simultaneously, the first rotating rod is driven by the transmission between the two transmission rollers and the transmission belt. The second rotating rod rotates in conjunction with the cleaning brush to clean the rising observation window, facilitating subsequent observation by staff and improving the practicality of the device. By rotating the locking block into one of the C-shaped blocks and connecting it with the magnetic block, the protective door can be quickly locked. When the protective door needs to be opened, it can also be quickly unlocked, making it convenient for staff to operate. The existing municipal pipeline network negative pressure water supply device has a fixed height, which is inconvenient to adjust the height of the box according to the height of the connecting pipe, resulting in poor adaptability. Since the water supply is connected to the inlet pipe, it is inconvenient to filter the water supply, and impurities can easily enter the pump body, affecting its use and causing certain adverse effects on users. Therefore, we propose a municipal pipeline network negative pressure water supply device. Utility Model Content
