DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] In the drawings, the sizes of components, layer thicknesses, or regions may be exaggerated for clarity. Therefore, any implementation of the present disclosure is not necessarily limited to the dimensions shown in the drawings, and the shapes and sizes of components in the drawings do not reflect true proportions. Furthermore, the drawings schematically illustrate idealized examples, and any implementation of the present disclosure is not limited to the shapes or values ​​shown in the drawings.

[0031] The embodiment of the present application provides an air gun controller housing, comprising: a bottom wall and a cover plate 100;

[0032] like Figures 1 to 5As shown, the bottom wall is provided with two opposite first side walls 101, and the bottom wall is provided with two second side walls 102, and the two second side walls 102 are arranged between the two first side walls 101.

[0033] A receiving chamber with an opening is formed, and the receiving chamber is used to receive the air gun control assembly. The two first side walls 101 constitute the two side boundaries of the receiving chamber, and the two second side walls 102 also constitute the other two side boundaries of the receiving chamber. The two second side walls 102 and the two first side walls 101 together form a rectangular frame. The space inside this rectangular frame is the receiving chamber, which is used to place the air gun control assembly. The cover plate 100 is arranged at the opening of the receiving chamber, and the cover plate 100 closes the opening of the receiving chamber. A plurality of connecting bases 301 are provided on the two first side walls 101.

[0034] The bottom wall, the cover plate 100, the two first side walls 101 and the two second side walls 102 form a rectangular shell (i.e., the air gun controller shell), and the internal space of the rectangular shell is the accommodating chamber, which is used to place the air gun control component and seal and protect the air gun control component. The air gun control component includes a circuit board and a control chip and other control elements for controlling the operation of the air gun source. In order to increase the anti-deformation and sealing effect of the rectangular shell, the bottom wall, the two first side walls 101 and the two second side walls 102 are integrally carved from a whole piece of stainless steel metal material. This integral carving process can ensure that the various parts of the rectangular shell are tightly combined without seams, thereby improving the strength and sealing of the shell. In addition, the stainless steel material has good corrosion resistance and can be used in seawater for a long time without rusting.

[0035] Specifically, in order to facilitate the installation of the air gun control assembly into the accommodating cavity, the end faces of the two first side walls 101 away from the bottom wall and the end faces of the two second side walls 102 away from the bottom wall are formed with a connecting end face 103. The cover plate 100 and the connecting end face 103 are detachably connected. The cover plate 100 is arranged at the opening of the accommodating cavity to close the opening of the accommodating cavity, wherein the cover plate 100 and the connecting end face 103 are sealed in a connected state, thereby playing a sealing role. The cover plate 100 and the connecting end face 103 are detachably connected by connecting screws. This connection method is convenient for users to perform maintenance and replacement operations, and ensures the firmness and sealing of the connection.

[0036] Specifically, in order to achieve a sealed connection between the cover plate 100 and the connection end face 103, the sealing effect is enhanced in the connected state. A sealing ring 107 is provided on the side of the cover plate 100 close to the connection end face 103. The sealing ring 107 is located in the accommodating cavity and extends into the accommodating cavity, and the sealing ring 107 is close to the edge of the accommodating cavity, that is, close to the first side wall 101 and the second side wall 102. A first sealing ring 108 is embedded in the periphery of the sealing ring 107. And on the cover plate 100

[0037] When assembled on the connecting end face 103, the first sealing ring 108 abuts against the first side wall 101 and the second side wall 102. This seals the receiving cavity, thereby achieving a sealed assembly of the cover plate 100. This forms a reliable sealing layer. This sealing layer effectively prevents seawater or other liquids from seeping into the receiving cavity through the gap between the connecting end face 103 and the cover plate 100. When the cover plate 100 is tightly fitted to the connecting end face 103, the sealing ring 107 and the first sealing ring 108 effectively prevent seawater or other liquids from entering the receiving cavity.

[0038] like Figure 3 As shown, further, to enhance the sealing effect, in addition to the first sealing ring 108, the cover plate 100 is also embedded with a second sealing ring 109 located between the cover plate 100 and the connecting end face 103. Furthermore, the second sealing ring 109 is located close to the sealing ring 107, so that the first sealing ring 108 and the second sealing ring 109 form an L-shaped sealing layer that fits the first side wall 101, the second side wall 102, and the connecting end face 103, thereby ensuring the sealing of the rectangular shell. The L-shaped sealing layer can better adapt to the shape of the rectangular shell, increase the sealing area, and improve the sealing effect. In addition, the second sealing ring 109 can also act as a buffer, reducing collision and wear between the cover plate 100 and the connecting end face 103.

[0039] like Figure 1 As shown, to ensure the stability of the cover plate 100 and the connecting end surface 103 when connected, the cover plate 100 is provided with a plurality of connecting screw holes 104, and the connecting end surface 103 is provided with mating screw holes 105 that correspond one-to-one with the connecting screw holes 104. The cover plate 100 and the connecting end surface 103 are connected by connecting screws that penetrate through the connecting screw holes 104 and the mating screw holes 105. The cover plate 100 and the connecting end surface 103 are detachably connected by the connecting screws. This connection method not only facilitates user maintenance and replacement operations, but also ensures a secure and sealed connection.

[0040] When connecting the cover plate 100 to the connection end surface 103, the cover plate 100 is placed on the connection end surface 103, and the connection screw holes 104 on the cover plate 100 are aligned with the matching screw holes 105 on the connection end surface 103. The connection screws are then threaded into the connection screw holes 104 and the matching screw holes 105, so that the cover plate 100 is fixed to the connection end surface 103 by the connection screws. This prevents the rectangular housing from being shaken or impacted in the sea, which may cause the connection between the cover plate 100 and the connection end surface 103 to loosen, thereby causing the seal to fail.

[0041] Furthermore, when the connecting screw is assembled into the connecting screw hole 104 and the matching screw hole 105

[0042] When the rectangular housing is struck, the end of the connecting screw will remain outside the connecting screw hole 104, meaning that the end of the connecting screw will protrude from the surface of the cover plate 100. This protruding end of the connecting screw is easily struck and damaged when the rectangular housing is impacted. This deforms the screw thread groove, making it no longer compatible with a screwdriver. This makes it difficult to turn the connecting screw with a screwdriver, making disassembly difficult. Therefore, to prevent the end of the connecting screw from being damaged during an impact, the screw thread groove is deformed. A receiving groove 106 is defined on the cover plate 100 at the location of the connecting screw hole 104. This allows the end of the connecting screw to be placed within the receiving groove 106, concealing it beneath the surface of the cover plate 100. This concealment of the end of the connecting screw beneath the surface of the cover plate 100 during an impact with the rectangular housing avoids the risk of damage to the end of the connecting screw. This prevents damage to the end of the connecting screw, which could hinder subsequent removal.

[0043] like Figure 1As shown, further, when the air gun control assembly is subsequently maintained and replaced, the cover plate 100 needs to be removed. During removal, since the first sealing ring 108 abuts against the first side wall 101 and the second side wall 102, the cover plate 100 cannot be easily removed after the connecting screws are removed. A tool such as a screwdriver is often required to pry up and remove the cover plate 100. However, in the process of using a screwdriver to pry the cover plate 100, it is easy to damage the first sealing ring 108 and the second sealing ring 109. In order to facilitate subsequent disassembly without damaging the first sealing ring 108 and the second sealing ring 109, at least two disassembly screw holes 110 are formed through the cover plate 100, and the positions of the disassembly screw holes 110 are located within the connecting end surface 103. When removing the cover plate 100, a matching screw is placed in the disassembly screw hole 110, and then the screw is rotated. The screw moves toward the inside of the disassembly screw hole 110 and passes through the disassembly screw hole 110 to abut against the connecting end face 103, so that the screw cannot continue to move. Then continue to rotate the screw. The screw rotates in place on the connecting end face 103, and the cover plate 100 that matches the screw thread through the disassembly screw hole 110 will be pushed by the screw, so that the cover plate 100 is lifted and detached from the connecting end face 103. In the process of removing the cover plate 100, there is no need to use tools to pry up the cover plate 100, thereby avoiding damage to the first sealing ring 108 and the second sealing ring 109. This design not only simplifies the disassembly process, but also avoids the risk of damaging the first sealing ring 108 and the second sealing ring 109 during the disassembly process. It has a simple structure and does not require the addition of

[0044] Compared with adding a buckle, the disassembly screw hole 110 has lower manufacturing cost and simpler manufacturing steps, and is more labor-saving when disassembling, as there is no need to pull the cover plate 100 with force, which is more labor-saving.

[0045] Specifically, two disassembly screw holes 110 can be formed through the cover plate 100, and the disassembly screw holes 110 are symmetrically arranged on the cover plate 100. The two disassembly screw holes 110 are equivalent to two fulcrums for lifting the cover plate 100. The symmetrical arrangement allows the lifting force on the cover plate 100 to be relatively uniform, thereby better lifting the cover plate 100.

[0046] like Figure 1As shown, further, in order to connect the air gun control assembly with other components of the air gun source in the outside world, multiple connection bases 301 are provided on both first side walls 101. A connection base 301 is provided on both first side walls 101. The end of the connection base 301 facing the air gun control assembly is connected to the air gun control assembly, and the end of the connection base 301 away from the air gun control assembly is connected to a cable, which is then connected to other components of the air gun source, thereby controlling the operation of the air gun source. The number of connection bases 301 provided can increase the number of devices that can be connected to the air gun control assembly, meeting the needs of existing air gun source system production and future interface expansion.

[0047] Furthermore, to facilitate maintenance and replacement of the connection base 301, the first side wall 101 is provided with a plurality of connection through-holes 201. The connection base 301 is assembled on the first side wall 101 through the connection holes 201, and the connection base 301 is threadedly connected to the connection holes 201. The connection base 301 is threadedly connected to the first side wall 101 through the connection holes 201 and can be replaced with a different connection base 301 as needed.

[0048] Specifically, the connection base 301 includes a sixteen-core base, a two-core base, a female four-core base, a male and female four-core base, and an eight-core base.

[0049] like Figure 5 As shown, to ensure the sealing of the rectangular housing at the connection base 301, a third sealing ring 202 is embedded on one side of the connection base 301 near the connection hole 201. When the connection base 301 is connected to the first side wall 101 through the connection hole 201, the third sealing ring 202 surrounds the connection hole 201 and abuts against the first side wall 101 to achieve sealing.

[0050] During installation, install the air gun control assembly into the accommodating cavity, and then

[0051] The connecting base 301 is installed to the connecting hole 201, ensuring that the third sealing ring 202 on the connecting base 301 abuts and seals against the first side wall 101, and the connecting base 301 is connected to the air gun control assembly. After the connection is completed, the cover plate 100 is installed to the connecting end face 103, so that the sealing ring 107 enters the accommodating cavity and each of the connecting screw holes 104 and each of the matching screw holes 105 correspond one to one. The connecting screws are then threaded into the connecting screw holes 104 and the matching screw holes 105, so that the cover plate 100 is fixed to the connecting end face 103 by the connecting screws. At this time, the first sealing ring 108 abuts against the first side wall 101 and the second side wall 102, and the second side wall 102 abuts against the connecting end face 103, achieving a seal and completing the installation of the air gun controller housing.

[0052] When disassembling the air gun controller housing, first use a screwdriver or other tool to rotate each of the connecting screws so that the connecting screws exit from each of the connecting screw holes 104 and each of the matching screw holes 105, thereby eliminating the fixed connection between the cover plate 100 and the connecting end face 103. However, at this time, a sealing ring 108 on the sealing ring 107 is still in contact with the first side wall 101 and the second side wall 102, making it impossible to directly remove the cover plate 100 from the opening of the accommodating cavity. Therefore, after removing the connecting screws, a matching screw is placed in the disassembly screw hole 110, and then the screw is rotated. The screw moves toward the inside of the disassembly screw hole 110, passes through the disassembly screw hole 110, and abuts against the connecting end face 103, preventing the screw from moving further. The screw is then continuously rotated, rotating in place on the connection end surface 103. The cover plate 100, whose threads mate with the screw through the disassembly screw hole 110, is then pushed by the screw, lifting the cover plate 100 and separating it from the connection end surface 103. This increases the gap between the cover plate 100 and the connection end surface 103, while the contact area between the sealing ring 108 and the first and second side walls 101, 102 decreases, reducing resistance, until the contact between the sealing ring 108 and the first and second side walls 101, 102 completely disappears. The cover plate 100 is then removed, completing the disassembly of the rectangular housing.

[0053] The air gun controller housing is formed by carving a whole piece of stainless steel metal material, which ensures high mechanical strength, strong impact resistance and corrosion resistance, and can ensure that the internal circuit of the housing can work stably under harsh construction environments. Two sealing rings are embedded on the cover plate 100, which can effectively prevent seawater from entering the housing. A disassembly screw hole 110 is provided so that when disassembling the air gun controller housing, there is no need to pry the cover plate.

[0054] Cover plate 100 eliminates the risk of damage to the two sealing rings during disassembly. It offers excellent corrosion and wear resistance, effectively resisting the erosion and abrasion of seawater. Furthermore, the optimized internal structure of the housing effectively prevents seawater infiltration and ingress, protecting the airgun control components.

[0055] The air gun controller housing provided in the embodiment of the present application has the advantages of simple structure, reliable performance, easy installation and maintenance, etc. It can meet the control requirements of the air gun source system in marine seismic exploration and has broad application prospects.
