[0016] The following further details the specific embodiments of the present utility model, such as the shapes, structures, mutual positions and connection relationships of the various components involved, the functions of each part, and the working principles, by describing the embodiments with reference to the drawings.

[0017] As Figures 1-4 shown, this underwater hydraulic sealing door system includes a door frame 1, a door body 2, guide rails 3 and guide rollers 4. The guide rails 3 are fixed on one side surface of the frame of the door frame 1. There are two guide rails 3, which are respectively arranged on the two side frames of the door frame 1 frame. The two guide rails 3 are arranged in parallel, and the length of the guide rails 3 is longer than the length of the door frame 1 frame. Guide rollers 4 are arranged at the four corners of one side surface of the door body 2. The guide rollers 4 are stuck on the guide rails 3 and slide on the guide rails 3. A hydraulic cylinder 5 is arranged on the outer side surface of the guide rails 3. One end of the hydraulic cylinder 5 is hinged to the outermost end of the door frame 1, and the other end is hinged to the outer side surface end of the guide rails 3. The hydraulic cylinder 5 is connected to an oil pressure control pipeline.

[0018] The above-mentioned hydraulic sealing door system includes a clamping device, which includes a clamping terminal 6. There are multiple clamping terminals 6, and clamping pins 7 are arranged on the clamping terminals 6. The clamping terminals 6 are arranged in parallel at the ends of the outer frame of the door frame 1. A clamping hole 8 is arranged at one end of the outer frame of the door body 2, and a clamping terminal is arranged at the other end. The clamping pins 7 are arranged corresponding to the clamping holes 8, and the clamping pins 7 can be inserted into the clamping holes 8 to prevent the door body 2 from shaking.

[0019] A clamping terminal is arranged at one end of the outer frame of the door frame 1, and a clamping hole 8 is arranged at the other end. The clamping hole 8 on the outer frame of the door frame 1 matches the clamping terminal on the door body 2, and a sealing ring 9 is arranged at the joint of the door frame 1 and the door body 2.

[0020] The device has clamping terminals on both the door frame 1 and the door body 2, and clamping holes 8 are also provided on the door frame 1 and the door body 2. When the door body 2 slides to completely overlap with the door frame 1 through the hydraulic cylinder 5, the clamping nails 7 on the door frame 1 are inserted into the clamping holes 8 of the door body 2, and the clamping nails 7 on the door body 2 are inserted into the clamping holes 8 of the door frame 1. In this way, the door frame 1 and the door body 2 are tightly combined without shaking, and the sealing ring 9 provided between the door frame 1 and the door body 2 plays a sealing role.

[0021] After the underwater hydraulic sealing door control system receives the closing signal, the oil pump is started to suck the hydraulic oil from the oil tank and transport it to the hydraulic cylinder 5 through the oil pressure control pipeline, thereby driving the piston rod to extend outward and driving the door body 2 to slide to one side along the guide rail 3 and fit closely to the door frame 1, so as to close the underwater hydraulic sealing door. Conversely, when the control system receives the opening signal, the hydraulic oil flows back from the hydraulic cylinder to the oil tank, the pressure in the hydraulic cylinder decreases, and the force direction of the piston rod changes to inward contraction, pushing the door body to slide to the other side along the guide rail, so as to open the underwater hydraulic sealing door.

[0022] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
