Description

Technical Field

[0001] The utility model relates to the field of marine seismic exploration, in particular to a coherent gun disassembly device used for marine seismic exploration. Background Art

[0002] In marine seismic exploration, a coherence gun is commonly used to release energy to stimulate seismic waves. A coherence gun, also known as a combination gun, consists of two air guns. Each air gun includes an air reservoir, a gun shuttle, and a clamp. Specifically, the rear end of the gun shuttle extends into the inner cavity of the air reservoir, while the front end of the gun shuttle extends beyond the front end of the air reservoir and is fixedly connected to the front end of the air reservoir via a clamp. When the two air guns are combined into a coherence gun, the clamps on the two air guns are fixedly connected together by a connector, and the rear ends of the two air reservoirs are also fixedly connected by a connector. Two chains are used to pull up the connectors at the front and rear ends of the coherence gun, allowing the coherence gun to be suspended in the air.

[0003] When the coherent gun is to be maintained, the two clamps at the head end of the coherent gun need to be removed, and the two gun shuttles need to be pulled out from the inner cavity of the two air cylinders respectively. The traditional method usually uses a hoist chain to be fixed on the head end of the two air cylinders and pulled up. Even if the clamp, connector and chain at the head end of the coherent gun are removed, the hoist chain at the neck of the air cylinder and the chain at the tail end of the air cylinder can still suspend the coherent gun in the air, thereby preventing the coherent gun from losing balance and falling from the air, avoiding accidental damage to the coherent gun and ensuring the work safety of the staff.

[0004] However, the traditional method has many limitations in actual use. Since the hoist chain needs to pull up the head end of the air cylinder, and the space at the head end of the air cylinder is limited, the hoist chain will always touch the clamp and get stuck at the clamp. On the one hand, it is easy to cause damage to the clamp. When the coherent gun is maintained and reinstalled, it is easy to cause the gun shuttle and the air cylinder to be fixed loosely, causing the coherent gun to work unstable. On the other hand, it will cause the gun shuttle to be dismantled and jammed, hindering the subsequent work process. The entire disassembly work needs to be carried out by multiple staff members together, which has low work efficiency and wastes a lot of manpower, material and financial resources. Utility Model Content

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0017] In addition, in the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0018] See also Figure 1 The utility model provides a coherent gun disassembly device for marine seismic exploration, comprising a connecting rod 1 and an adjusting hoop mechanism group. Preferably, the length dimension of the connecting rod 1 is set to 1000 mm, the height dimension of the connecting rod 1 is set to 400 mm, and the width dimension of the connecting rod 1 is set to 10 mm; the adjusting hoop mechanism group comprises two adjusting hoop mechanisms 2 respectively connected to the two ends of the connecting rod 1, the adjusting hoop mechanism 2 comprises an adjusting rod 210 and a connecting hoop 220, the adjusting rod 210 is connected to the connecting rod 1, and the connecting hoop 220 is fixedly connected to the adjusting rod 210. Preferably, the inner diameter dimension of the connecting hoop 220 is set to 224 mm, so that the connecting hoop 220 can be tightly connected to the air cylinder to prevent the connection between the connecting hoop 220 and the air cylinder from shaking.

[0019] The basic working principle of the coherent gun disassembly device for marine seismic exploration involved in the present invention is: when the coherent gun needs maintenance, the two connecting clamps 220 at both ends of the connecting rod 1 are respectively connected to the outer peripheral surfaces of the two air storage cylinders of the coherent gun, and the hoist chain is used to pull up the connecting rod 1. Since the hoist chain does not directly contact the coherent gun but acts on the connecting rod 1, it can effectively prevent the hoist chain from touching the clamp of the coherent gun and getting stuck at the clamp of the coherent gun, thereby avoiding damage to the clamp of the coherent gun and preventing the gun shuttle from being stuck during disassembly, greatly reducing the number of staff required for the entire disassembly work. In actual use, one person can complete the disassembly work of the coherent gun, thereby improving work efficiency.

[0020] See also Figure 1 The present invention is further described below with a specific embodiment:

[0021] In this embodiment, see Figure 1 As a preferred design, a plurality of connecting holes 110 are provided on the side of the connecting rod 1, and the plurality of connecting holes 110 are evenly arranged along the length extension direction of the connecting rod 1, a plurality of adjusting holes 211 are provided on the side of the adjusting rod 210, and the plurality of adjusting holes 211 are evenly arranged along the length extension direction of the adjusting rod 210. Preferably, a plurality of connecting holes 110 are respectively provided at both ends of the side of the connecting rod 1; the adjusting clamp mechanism 2 further includes a bolt, and the adjusting rod 210 is mounted on the connecting rod 1 by the bolt, and the bolt passes through the adjusting rod 210. The adjustment hole 211 is installed in the connecting hole 110 on the connecting rod 1. Since the coherent gun is composed of two air guns, in actual use, the distance between the two air guns can be flexibly set according to actual conditions. Therefore, the adjusting rod 210 is installed in different connecting holes 110 on the connecting rod 1 by bolts. The distance between the two adjusting rods 210 can be flexibly adjusted according to the actual conditions of the coherent gun. Preferably, the diameters of the connecting hole 110 and the adjustment hole 211 are both set to 15 mm; preferably, the two adjusting rods 210 are located on the same side of the connecting rod 1.

[0022] In this embodiment, see Figure 1 As a preferred design, a hanging block 120 is also fixedly provided on the connecting rod 1, and a through hole is opened on the hanging block 120, and the hoist chain can pass through the through hole and pull up the connecting rod 1. Preferably, the hanging block 120 is set at the center of the connecting rod 1. When the hoist chain pulls up the connecting rod 1 through the through hole, the coherence gun can be prevented from tilting in the air; preferably, the connecting rod 1 and the hanging block 120 are integrated, which can simplify the overall structure and facilitate production and manufacturing; preferably, the diameter of the through hole is set to 40-50mm, which can facilitate the hoist chain to pass through the through hole.

[0023] As can be seen from the above, the coherent gun disassembly device for marine seismic exploration of the present invention has the following beneficial effects:

[0024] By setting the connecting rod 1 and the adjusting clamp mechanism group, when the coherent gun needs maintenance, the two connecting clamps 220 are respectively connected to the outer peripheral surfaces of the two air cylinders of the coherent gun. When the hoist chain is used to pull up the connecting rod 1, the hoist chain can be effectively prevented from touching and getting stuck at the clamp of the coherent gun, thereby avoiding damage to the clamp of the coherent gun, and preventing the gun shuttle from being stuck during removal, thereby improving work efficiency.
