DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] Embodiment: A mechanical deep-sea fixed depth tripping device, see attached Figure 1 -Attached Figure 4, including a shell 1, a sealing cylinder 3, a piston 4, a piston rod 5, an elastic member 8 and a connecting member 7, wherein one end of the shell 1 is connected to a handle, and the other end is rotatably connected to two clamps 2, and the two clamps 2 are rotated to clamp and release the detector; the two ends of the sealing cylinder 3 are sealed; the piston 4 is arranged in the sealing cylinder 3 and can slide in the sealing cylinder 3 along the length direction of the sealing cylinder 3; the piston rod 5 extends into the sealing cylinder 3 from the end of the sealing cylinder 3 close to the clamp 2 and is connected to the piston 4, the piston rod 5 can slide along the length direction of the sealing cylinder 3 on the shell 1 and the end of the piston 4 extending out of the sealing cylinder 3 contacts the external seawater; the elastic member 8 is arranged in the sealing cylinder 3 and is located at the end of the piston 4 away from the elastic rod, and the elastic member 8 is in a compressed state; the two ends of the connecting member 7 are respectively connected to the piston rod 5 and the clamp 2, when the piston 4 is located at the end of the sealing cylinder 3 close to the clamp 2, the two clamps 2 are in a clamped state, and when the piston 4 is located at the end of the sealing cylinder 3 away from the clamp 2, the clamp 2 is in a relaxed state.

[0021] In the deep sea, as the depth of the device is increased, the water pressure will gradually increase, and there is a positive correlation between the water pressure and the depth of the device. By setting an elastic member 8 in the sealing cylinder 3, the piston 4 is pushed to the end of the sealing cylinder 3 close to the clamp 2 under the action of the elastic member 8. At this time, under the action of the piston rod 5 and the connecting member 7, the clamp 2 is in a clamped state, and then the detector is released. As the device gradually falls, the pressure gradually increases, and the water pressure will directly act on the piston rod 5. When the water pressure is greater than the elastic force of the elastic member 8, the piston rod 5 will be pushed to move in the direction close to the elastic member 8, and then the elastic member 8 will be squeezed by the piston 4 until the piston 4 moves to a position close to the end of the sealing cylinder 3 away from the clamp 2. At this time, under the action of the piston rod 5 and the connecting member 7, the clamp 2 is in a relaxed state, that is, the clamp 2 is opened to realize the release of the detector. It is only necessary to select an elastic member 8 with appropriate elasticity according to the release depth to achieve accurate release at a specified depth.

[0022] Specifically, a sealing plug 31 is provided at one end of the sealing cylinder 3 close to the clamp 2, and a through hole 311 is provided on the sealing plug 31 for the piston rod 5 to pass through, and a sealing tape 32 is provided on the hole wall of the through hole 311. The sealing tape 32 can prevent the external seawater from entering the sealing cylinder 3 through the hole wall of the through hole 311 and the piston rod 5.

[0023] Specifically, an axial hole 51 is provided in the piston rod 5, and the axial hole 51 passes through the piston rod 5 toward the end of the piston rod 5 away from the piston 4; the axial hole 51 is provided with a radial hole 52 that passes through the piston rod 5 outwardly at the end close to the piston 4. When the piston 4 is located at the end of the sealing cylinder 3 close to the clamp 2, the radial hole 52 is located in the through hole 311 and on the side of the sealing belt 32 away from the piston 4.

[0024] By setting the radial hole 52 and the axial hole 51, when the water pressure is not reached, the radial hole 52 is located on the side of the sealing belt 32 away from the piston 4, and the external water cannot enter the sealing cylinder 3 through the radial hole 52. When the piston rod 5 moves toward the elastic member 8 and drives the radial hole 52 to cross the sealing belt 32, the radial hole 52 will be connected with the sealing cylinder 3, and then seawater will be injected into the sealing cylinder 3, so that the water pressure of the seawater can fully act on the piston 4.

The wear-resistant belt 33 can play a sealing role to prevent the radial hole 52 from communicating with the external seawater through the gap between the piston rod 5 and the through hole 311.

[0026] Specifically, an adjustment seat 9 is provided at the end of the sealing cylinder 3 away from the piston 4, and the end of the elastic member 8 away from the piston 4 is pressed against the adjustment seat 9; an outer side of the end of the sealing cylinder 3 away from the piston 4 is threadedly connected with an adjustment bolt 91, and one end of the adjustment bolt 91 extends into the sealing cylinder 3 and is connected to the adjustment seat 9.

[0027] By rotating the adjusting bolt 91 , the adjusting seat 9 can be pushed to squeeze the elastic member 8 , thereby adjusting the elastic force of the elastic member 8 acting on the piston 4 , so that different depths of delivery can be achieved through one elastic member 8 .

[0028] Specifically, the elastic member 8 is configured as a spring.

[0030] Specifically, the connecting member 7 is configured as a connecting plate, one end of which is hinged on the buffer cylinder 6, and the other end is hinged on the end of the caliper close to the buffer cylinder 6. One end of the caliper is connected to the corresponding connecting plate, and the other end is used to clamp and release the detector, and the middle position of the caliper is connected to the housing 1; in this embodiment, two calipers are respectively located on both sides of the buffer cylinder 6. When the piston 4 is located at one end of the sealing cylinder 3 close to the caliper, the two connecting plates rotate to be in a straight line under the action of the piston rod 5, thereby pushing the ends of the two calipers close to the sealing cylinder 3 to rotate in a direction away from each other, and then driving the ends of the two calipers away from the sealing cylinder 3 to rotate in a direction close to each other to achieve the clamping action of the two calipers; when the piston 4 moves to the end of the sealing cylinder 3 away from the caliper, the ends of the two connecting plates close to the buffer cylinder 6 are driven by the piston rod 5 to rotate in a direction close to the sealing cylinder 3, and then drive the ends of the two calipers close to the sealing cylinder 3 to rotate in a direction close to each other, thereby driving the ends of the two calipers away from the sealing cylinder 3 to rotate in a direction away from each other, and then the two calipers complete the opening action.

[0031] Specifically, an auxiliary channel is provided in the housing 1, and the portion of the piston rod 5 extending out of the sealing cylinder 3 and the buffer cylinder 6 are located in the auxiliary channel. The auxiliary channel can guide the sliding direction of the piston rod 5 and the buffer cylinder 6.

[0032] Specifically, an elastic member 61 is provided in the auxiliary channel, and the two ends of the elastic member 61 are respectively pressed against the housing and the end of the buffer cylinder 6 close to the piston rod 5. Specifically, the elastic member 61 is configured as a spring and is sleeved outside the piston rod 5.

[0033] Specifically, when the sealing cover 92 is connected to the sealing cylinder 3 , the sealing cover 92 is disposed outside the adjusting bolt 91 .
