Novel anti-freezing outdoor encryption type fire hydrant
The invention discloses a novel anti-freezing outdoor encryption type fire hydrant. The fire hydrant comprises an upper shell, a valve element, water outlets and an outer shell, the upper shell is installed on the valve element, the water outlets are located in the two sides of the valve element, the upper shell is installed on the outer shell in an embedded mode and is characterized in that a coating is arranged on inner wall of one side of shell and faces convex lens, convex lens is fixedly connected with shell in sealed mode, and base is welded to bottom of shell. The automatic unfreezing device is simple in structure and easy to maintain, a water source in the hydrant is automatically unfrozen under the irradiation of sunlight, the curved reflecting mirror is beneficial to better lightcondensation, no electric appliance power source is needed, the municipal cost is saved, and whether water exists in the hydrant or not can be judged through the floating ball.
本发明公开了一种新型防冻室外加密型消防栓，包括上壳、阀芯、出水口、外壳，上壳安装于阀芯上，出水口位于阀芯两侧，上壳嵌入安装于外壳上，其特征在于：外壳一侧内壁设有涂层，涂层面向有凸透镜，凸透镜与外壳密封固定连接，外壳底部焊接有底座，本发明结构简单，易于维护保养，且在有阳光照射下自动为栓内水源进行解冻，曲状的反射镜有助于更好的聚光，且本发明无需使用任何电器电源，节约了市政成本，且可通过浮球判断出栓内是否有水。
