The invention provides a municipal umbrella-like temporary guarding device for a sewer inspection shaft opening, and belongs to the field of municipal administration. The municipal umbrella-like temporary guarding device includes a rod body. An upper end head of the rod body is fixedly connected with a connecting circular block horizontally. A plurality of first guarding rods are connected with the circular side wall of the connecting circular block though a hinge in a surrounding mode evenly and fixedly. The rod body is provided with a cylindrical sliding sleeve in a sleeved mode. A pluralityof second guarding rods are connected with the circular side wall of the cylindrical sliding sleeve though a hinge in a surrounding mode evenly and fixedly. A movable end head of each second guardingrod is connected with the corresponding first guarding rod through hinges correspondingly. According to the municipal umbrella-like temporary guarding device, the rod body is used for being vertically inserted in the shaft opening, then the cylindrical sliding sleeve slides relative to the rod body, the distance between the cylindrical sliding sleeve and the connecting circular block at the upperend of the rod body is shortened, so that the first guarding rods and the second guarding rods are opened up outwards through hinge butt points, the second guarding rods are horizontally supported atthe edge of the upper side of the shaft opening, debris and pedestrians are prevented from falling into a sewer inspection shaft, and a storage battery box is used for storing a storage battery.
Description
technical field [0001] The invention relates to municipal equipment, in particular to an umbrella-shaped temporary protection device for municipal sewer inspection wells. Background technique [0002] Municipal administration mainly involves the construction planning of all aspects of the city. It is to maintain the image of the city and strengthen urban planning management, such as road construction and maintenance, urban garbage disposal, etc. Among them, the sewer is a kind of urban public facility, which is mainly used to discharge building sewage and Rainwater, in order to maintain or repair the sewer frequently, it is necessary to reserve some inspection wells on the ground to drill into the sewer for inspection or repair the sewer. For safety reasons, the sewer maintenance master often needs to A warning sign is erected at the entrance of the sewer to prevent passing people from falling into the sewer unprepared, but most of the current warning devices are a few plast...
