DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] Figure 1-Figure 4 A specific embodiment of the utility model is a hydraulically driven lifting hole cover plate automatic unsealing device, such as Figure 1 As shown, the main body is composed of a cover plate 101, a hydraulic rod 102 and a hydraulic drive device 103. The cover plate 101 is fixed to the floor slab through a cover plate rotating shaft 107 on the side of the lifting hole close to the wall. One end of the hydraulic rod 102 is hinged to the cover plate 101 through a hinge point 104, and the other end is hinged and fixed to a wall 109 near the lifting hole through a hinge point 105. The hydraulic drive device 103 is fixed to the wall 109 and connected to the hydraulic rod 102 through a hydraulic oil circuit 106. In this embodiment, the hydraulic rod 102 can be retracted and extended by using a switch on the hydraulic drive device 103, thereby driving the cover plate 101 to rotate around the cover plate rotating shaft 107, thereby realizing the automatic opening and closing of the cover plate 101.

[0024] like Figure 2 As shown, the cover plate 101 should be larger than the lifting hole 210 by more than 10 cm on all sides after installation. In the embodiment, the hinge point 105 between the hydraulic rod 102 and the wall 109 is fixed on the steel plate 212, and then the steel plate 212 is fixed to the wall 109 in a matrix arrangement by multiple rivets 211, so as to realize the hinge fixation of the hydraulic rod 102 and the wall 109.

[0025] like Figure 3 As shown, the hydraulic rod used in the device is a two-stage telescopic hydraulic rod, including a hydraulic rod sleeve 301, a primary hydraulic telescopic rod 302 and a secondary hydraulic telescopic rod 303. In the embodiment, the secondary hydraulic rod 303 has a first connecting rod 304, and a first hinge ring 305 is fixed to the other end of the first connecting rod 304; a second connecting rod 306 is provided at one end of the hydraulic rod sleeve 301, and a second hinge ring 307 is fixed to the other end of the second connecting rod 306.
