Detailed Description
To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1-2, the pressure difference driven underwater telescopic power device comprises a shell 5, a piston 4 and a piston rod 6. The piston rod 6 penetrates through the shell 5 and is vertically and fixedly connected with the bottom of the piston 4. In order to ensure the sealing of the piston rod 6 during the movement, a dynamic sealing ring is arranged at the joint of the piston rod 6 and the housing 5. The casing 5 sets up to "T" shape structure, casing 5 sets up to withstand voltage shell, casing 5's material can be stainless steel, aluminum alloy, polymer composite, carbon fibre, glass fibre etc. do not do special restriction. The outer side wall of the top of the shell 5 is provided with a fixed mounting ring 2 which is fixedly connected with the shell 5 and protrudes out of the shell 5, so that the fixed connection with other devices is facilitated. The piston 4 is attached to the side wall of the inner cavity of the shell 5, and the inner cavity of the shell 5 is partitioned into an upper air chamber 3 and a lower air chamber 7.
The volume of the lower air chamber 7 is larger than that of the upper air chamber 3 so as to increase the stroke and output pressure of the piston 4. The upper air chamber 3 is provided with a first opening, and the first opening is convenient for the injection of subsequent seawater or other liquid or gas. The first opening is provided with a first adjusting mechanism 1 which seals or communicates the upper air chamber 3 with the outside of the shell 5. The first adjusting mechanism 1 is set as a first rubber sealing plug or a first electromagnetic valve. Of course, the first solenoid valve is preferred. When the first rubber sealing plug is selected, the first rubber sealing plug needs to be opened manually and then closed manually. The first electromagnetic valve is selected to control the opening and closing of the first electromagnetic valve to control the subsequent injection of seawater or other liquid or gas into the upper air chamber 3.
And a second opening is formed in the lower air chamber 7, and a second adjusting mechanism 8 for sealing or communicating the lower air chamber 7 with the outside of the shell 5 is arranged on the second opening. The second adjusting mechanism 8 is provided as a second rubber sealing plug or a second electromagnetic valve. Of course, a second solenoid valve is preferred. When the second rubber sealing plug is selected, the second rubber sealing plug needs to be opened manually and then closed manually. The second electromagnetic valve is selected to control the opening and closing of the second electromagnetic valve to control the subsequent injection of seawater or other liquid or gas into the lower air chamber 7. Of course, the first adjusting mechanism 1 and the second adjusting mechanism 8 are not limited to the above two mechanisms, and any existing device capable of opening and sealing the first opening and the second opening can be applied to the present device.
