Description

Technical Field

[0001] The present invention relates to the technical field of oil seismic ocean exploration, and particularly to a hanging device and a mounting device. Background Art

[0002] Marine seismic exploration is a common exploration operation. It mainly achieves the purpose of marine seismic exploration by releasing multiple seismic geophone nodes (referred to as nodes for short) to the seabed and then using each node released to the seabed to collect marine seismic data.

[0003] The specific usage method of the nodes is as follows: First, arrange hooks on each node, and then arrange hanging pipes at intervals on the rope in sequence. Then, release the rope by the node ship on the target survey line and hang the hooks one by one on the hanging pipes, thereby realizing the arrangement of the nodes on the rope, and then the nodes can be released to the seabed one by one to collect marine seismic data. Finally, the rope is recovered by the node ship, and the hooks on the nodes are detached from the hanging pipes on the rope, thereby recovering the nodes, and then the seismic data in the nodes can be exported to complete the marine seismic exploration.

[0004] When releasing and recovering the rope, the rope is released along the sailing direction of the node ship so that the nodes mounted on it are released to the target survey line.

[0005] Some types of nodes have directional requirements, so 2 hooks need to be arranged at the front and rear ends of the seismic geophone nodes respectively. This operation mode increases the complexity of the automatic hanging equipment, and at the same time requires a relatively large operation platform. Therefore, micro-small shallow-water operation ships cannot apply the relevant equipment to achieve automated operation.

[0006] In the shallow-water OBN operation area, only micro-small operation ships can be used. Limited by the available deck area, the existing automatic node release operation equipment cannot be installed, resulting in the relevant work in this type of sea area can only be carried out manually. To achieve the set operation speed (1.5 m / s), multiple operation personnel need to be configured, with high labor intensity, high operation risk, and high operation cost.

[0007] Therefore, how to reduce the operation risk and labor intensity during the node mounting operation using a micro-small operation ship has become an urgent technical problem to be solved. Summary of the Invention

[0008] In view of this, the present invention provides a hanging device and a mounting device.

[0009] Specifically, the present invention is realized through the following technical solutions:

[0010] According to a first aspect of the present invention, there is provided a hanging device for hanging a node, comprising: a first transmission device for transporting the node in a first direction, the first transmission device being provided with a hanging position; a second transmission device, the first transmission device and the second transmission device being cross-arranged for transporting a hanging tube in the second direction and capable of transporting the hanging tube to the hanging position; a hanging device, the hanging device being connected to the node, the hanging device being used to connect the hanging tube located at the hanging position.

[0011] The present invention provides a hooking device. Specifically, the hooking device includes a first transmission device, a second transmission device and a hooking device. The first transmission device is used to transport the node in the first direction, and transport the node to the hooking position of the first transmission device. Preferably, the node is a seismic detector node. The second transmission device is cross-arranged with the first transmission device, and is used to transport the hooking tube in the second direction, and can transport the hooking tube to the hooking position of the first transmission device, so that the hooking device can connect the hooking tube at the hooking position. By setting the hooking position and the hooking device, during operation, the node only needs to be manually placed in the first transmission device, and the hooking of the seismic detector node and the hooking tube on the rope can be quickly realized through the hooking device, thereby improving the hooking efficiency of the seismic detector node, and then the navigation speed of the node ship will not be affected by the low hooking efficiency of the seismic detector node and the rope.

[0012] Optionally, the model of the geophone node can be: Z100, Z700, Z3000, Mass, or OBX.

[0013] In the related technology, in the shallow sea OBN (Ocean Botton Node) operation area, only micro-sized operation vessels can be used. Due to the limitation of the available deck area, the existing automatic release node operation equipment cannot be installed, resulting in related work in this type of sea area can only rely on manual work. In order to achieve the set operating speed (1.5m / s), 8 to 9 people are required, who are mainly responsible for the transmission, hanging and release of the cable, which has high labor intensity, high operation risk and high operation cost.

[0014] By setting the hooking position and the hooking device provided by the present invention, the node only needs to be manually placed in the righting chute during operation, which reduces the operation risk and labor intensity. Under the condition of maintaining the operation speed (1.5m / s), the number of personnel can be reduced to 30% of the original.

[0015] In addition, the above-mentioned hooking device provided by the present invention may also have the following additional technical features:

[0016] In some technical solutions of the present invention, optionally, the hanging tube includes a sliding part and a hanging part, the sliding part is installed on the second transmission device, and is used to move with the movement of the second transmission device, and the hanging part is connected to the sliding part; the first transmission device includes: a first main body, and a hanging position is arranged on the first main body; the first main body includes a first transmission channel, which is used to transport the node, and the first transmission channel passes through the hanging position; a first straightening device is arranged on the first main body and is located at the hanging position, and when the node is located at the hanging position, the first straightening device is at least partially located above the node.

[0017] In this technical solution, the hanging tube includes a sliding part and a mounting part. The hanging tube is installed on a second transmission device (such as a rope) through the sliding part. When the second transmission device is transported, the sliding part drives the mounting part to move in the second direction along with the second transmission device. The mounting part is arranged below the sliding part to facilitate mounting with the node.

[0018] Furthermore, the first transmission device includes a first main body, a first transmission channel and a first straightening device, wherein the first transmission channel on the first main body cooperates with the node in a rolling manner to transport the manually pushed node to the hanging position, the hanging position is arranged on the first main body, and the hanging position is arranged at the end of the first transmission channel, and the node waits for hanging at the hanging position; the first transmission channel is arranged in the first main body and is used to transport the node, and the end of the first transmission channel is the hanging position; the first straightening device is arranged on the first main body and is located at the hanging position, the first straightening device includes a pulley, and when the node is located at the hanging position, the first straightening device is at least partially located above the node.

[0019] Specifically, the first straightening device is used to straighten the hook provided on the node during the process of the node moving to the hooking position, so that the hook is at 90 degrees. By providing the first straightening device, the hooking of the hooking tube and the hook can be quickly realized, thereby improving the hooking efficiency of the seismic detector node and the rope, thereby increasing the sailing speed of the node ship.

[0020] In some technical solutions of the present invention, optionally, the second transmission device includes a second upper body, the second upper body includes a door body, the door body is close to the side of the first transmission channel where the first straightening device is provided, and the door body is used to support the transportation channel of the hanging tube; a second lower body is connected to the door body and the first body, and is arranged parallel to the second upper body, and is used to support the first body and support the door body.

[0021] In this technical solution, the second transmission device includes a second upper body and a second lower body, and the second upper body and the second lower body are connected by a door body. The door body is located on the side close to the first straightening device, and the door body is used to carry the transportation channel of the hanging tube so that the hanging tube can be transported to the hanging position and hung with the node.

[0022] Furthermore, the second lower body is connected to the door body and the first body, that is, the door body and the first body are both located above the second lower body, and the second lower body is also arranged in parallel with the second upper body and cross-arranged with the first body, and the second lower body is used to carry the first body. A stable structure is established through the second upper body and the second lower body, and the first transmission device and the second transmission device are effectively connected, which helps to quickly realize the hanging of the hanging tube and the hook.

[0023] In some technical solutions of the present invention, optionally, the second transmission device also includes: a rope guide tube connected to the door body, the rope guide tube is an arc-shaped through groove, which is used to correct the transportation direction of the hanging tube so that the hanging part is aligned with the hanging device.

[0024] In this technical solution, the second transmission device also includes a rope guide tube, which is arranged on the door body. The rope guide tube is an arc-shaped through groove, which is convenient for the hanging tube to pass through. When working, the rope will move with the hanging tube in the direction of the rope guide tube during the process of being released into the water. The arc-shaped through groove cooperates with the moving hanging tube, and the hanging tube can be gradually straightened until it is facing the through groove, thereby ensuring that the hanging tube can run along the through groove of the rope guide tube, so as to be aligned with the hook on the node. By providing the rope guide tube, the hanging tube that is shaken by the rope can be straightened, which helps to quickly realize the hanging of the hanging tube and the hook.

[0025] Among them, the rope guide tube is horizontally installed on the door beam of the door body, and its central axis is parallel to the central axis of the second lower body, the central axis of the rope guide tube and the central axis of the first transport channel intersect vertically, and the through groove of the rope guide tube runs through both ends and the ends of both ends are provided with arc support surfaces.

[0026] In some technical schemes of the present invention, optionally, the hanging device includes: a fixed plate, connected to the node; a limiting beam, connected to the fixed plate; a hook limiter, arranged on the limiting beam, a hook, hinged to the hook limiter, and used to hang with the hanging tube located at the hanging position, the hook and the first straightening device are in rolling cooperation, wherein the hook limiter is used to limit the rolling angle of the hook when the hook and the first straightening device are in rolling cooperation.

[0027] In this technical solution, the hanging device includes a fixed plate, a limiting beam, a hook and a hook limiter. Among them, the fixed plate connects the node and the limiting beam. By setting the fixed plate, more contact surfaces are provided for the node to achieve a stable connection to prevent the node from being lost. At the same time, it also provides a mounting surface for the hanging device. Reasonable setting of the setting position of the limiting beam can make the hanging device connected with the node move more smoothly. A hook limiter is provided on the limiting beam. The hook limiter is hinged to the hook. Before contacting the first straightening device, the hook is parallel to the direction of the fixed plate. After contacting the first straightening device, the hook and the first straightening device are rollingly matched. Under the joint constraints of the first straightening device and the hook limiter, the hook is 90°, that is, it is perpendicular to the direction of the fixed plate. Among them, the hook limiter is used to limit the rolling angle of the hook when the hook and the first straightening device are rollingly matched. Preferably, the rolling angle of the hook is less than or equal to 90°.

[0028] In addition, since the current nodes are connected to the main cables using thinner cables, which is a soft connection, the layout posture of the nodes and the seabed is unstable when deployed on the seabed. By setting hooks and hinged with hook limiters, the posture stability of the nodes after seabed deployment is improved, avoiding the current problem of soft connection between the nodes and the main cables.

[0029] In some technical schemes of the present invention, optionally, the hook includes: a hanging rod; a hook body, connected to the hanging rod and hinged to the hook limiter, with a first opening between the hanging rod and the hook body; a locking plate, movably connected to the hook body, for closing the first opening when the mounting part does not contact the hanging rod or the mounting part enters the hanging rod, and opening the first opening when the mounting part contacts the hanging rod.

[0030] In this technical solution, the hook includes a hanging rod, a hook body and a locking piece. The hook body is connected to the hanging rod and the locking piece, and a first opening is formed between the hanging rod and the hook body. Before the hanging rod contacts the hanging tube, the first opening is closed by the locking piece and is in a normally closed state. After contacting the hanging tube, the locking piece at the first opening moves in the same direction of the hanging tube, i.e., in the second direction, under the pressure of the hanging tube. At this time, the first opening is in an open state. When the hanging tube is completely connected to the hanging rod, the locking piece returns to the position before the hanging rod contacts the hanging tube.

[0031] Among them, the central axis of the hook rod and the central axis of the hanging tube coincide with each other, that is, the hook and the hanging tube are hung together, and the hook and the hanging tube are in a hung state.

[0032] In addition, the hook further comprises an elastic member, which is respectively connected to one end of the hook body and the locking plate, and at this time, the other end of the locking plate is connected to the hook body. The elastic member is used to change the closed state or open state of the first opening according to the movement of the locking plate.

[0033] Specifically, the hanging connecting pipe continues to move in the through groove of the guiding rope pipe to the hook. The moving hanging connecting pipe enters the hanging rod of the hook and abuts against the locking piece and continues to push, completing the unlocking. The hanging connecting pipe continues to move forward along the hanging rod and crosses the locking piece, and the elastic piece causes the locking piece to return to its position and close, realizing the locking between the hook and the hanging connecting pipe, thereby realizing the hanging connection of the seismic geophone node on the rope.

[0034] In some technical solutions of the present invention, optionally, the first transmission device further includes: a gate, which is arranged on the side of the first transmission guide rail away from the door body.

[0035] In this technical solution, the first transmission device further includes a gate. The gate is located on the side of the first transmission guide rail away from the door body, is arranged opposite to the door body, and is on the side of the hanging position. The gate is used to, after the hanging connecting pipe and the hook are successfully connected, due to the influence of the continuous movement of the rope, the node connected to the hanging connecting pipe pushes open the gate in the second direction, realizing the release of the node. By setting the gate, the movement of the nodes that have not been connected is restricted, and the demand for automated operation in extremely shallow water areas is met.

[0036] It should be noted that the rope is released by the gravity of the seismic geophone node itself. The throwing of the rope, the hanging of the hook and the hanging connecting pipe are carried out simultaneously.

[0037] In some technical solutions of the present invention, optionally, the orientation of the gate is the same as the second direction.

[0038] In this technical solution, the opening direction of the gate is the same as the second direction, that is, the same as the moving direction of the hanging connecting pipe. As the rope continues to move, the node will push open the gate, thus finally realizing the release of the seismic geophone node. By opening the gate in the second direction to realize the release of the node, the demand for automated operation in extremely shallow water areas is met.

[0039] In some technical solutions of the present invention, optionally, the first main body further includes: limiting guide rails, which are arranged on both sides of the first transmission channel and are in a sliding fit relationship with the limiting beam and the fixed disk.

[0040] In this technical solution, the limiting guide rails are arranged on both sides of the first transmission channel, and the two limiting guide rails are parallel. The limiting beam, the fixed disk and the limiting guide rails cooperate with each other to make the node move in the first direction and then reach the hanging position, so that the staff only needs to put the node into the first transmission device and push it, greatly reducing the labor intensity of the staff. Thus, the demand for automated operation in extremely shallow water areas is met.

[0041] According to a second aspect of the present invention, a mounting device is provided, which is suitable for mounting the mounting device of the first aspect or any one of the technical solutions of the first aspect. The mounting device comprises: a rope and a plurality of mounting tubes, wherein the plurality of mounting tubes are installed on the rope at intervals along the length direction of the rope.

[0042] The mounting device provided by the present invention includes the mounting device of any one of the technical solutions in the first aspect, and thus has all the beneficial effects of any of the above technical solutions, which will not be repeated here.

[0043] The technical solution provided by the present invention brings at least the following beneficial effects:

[0044] (1) The present invention has a simple structure and a small size, and can be installed on a small and micro node operation ship, meeting the needs of automated operation in extremely shallow waters. At the same time, since the hook and the hanging pipe are hinged, the problem of easy loss and unstable layout caused by conventional soft ropes connecting the hook and the node is eliminated.

[0045] (2) Due to the increase in the node release speed, the node ship can sail at high speed, thereby offsetting the interference of ocean currents.

[0046] (3) The staff only needs to put the node into the righting slide and push it to the bottom, which greatly reduces the labor intensity of the staff.

[0047] (4) Due to the significantly high node release speed, the efficiency of seismic exploration operations is greatly improved, and costs are greatly saved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0065] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0066] For the device embodiments, since they basically correspond to the method embodiments, the relevant parts can refer to the partial descriptions of the method embodiments. The device embodiments described above are only illustrative. The units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed to multiple network units. Some or all of the modules can be selected according to actual needs to achieve the objectives of the solution of the present invention. Those of ordinary skill in the art can understand and implement it without creative efforts.

[0067] Referring to Figure 1 As shown, an embodiment of the present invention provides a hanging device 100 for hanging a node 200, including: a first transmission device 10 for transporting the node in a first direction, and the first transmission device 10 is provided with a hanging position; a second transmission device 20, the first transmission device 10 and the second transmission device 20 are arranged crosswise, for transporting a hanging pipe 210 in a second direction, and capable of transporting the hanging pipe 210 to the hanging position; a hanging device 30, the hanging device 30 is connected to the node 200, and the hanging device 30 is used to connect the hanging pipe 210 located at the hanging position.

[0068] The present invention provides a hanging device 100. Specifically, the hanging device 100 includes a first transmission device 10, a second transmission device 20, and a hanging device 30. The first transmission device 10 is used to transport the node in a first direction and transport the node to the hanging position of the first transmission device 10. Preferably, the node is a geophone node. The second transmission device 20 is arranged crosswise with the first transmission device 10, for transporting the hanging pipe 210 in a second direction, and capable of transporting the hanging pipe 210 to the hanging position of the first transmission device 10, so that the hanging device 30 can connect the hanging pipe 210 at the hanging position. By setting the hanging position and the hanging device 30, during operation, the node only needs to be manually placed into the first transmission device 10, and then the hanging of the geophone node and the hanging pipe 210 on the rope can be quickly realized through the hanging device 30, thereby improving the hanging efficiency of the geophone node, and further ensuring that the sailing speed of the node ship will not be affected due to the too low hanging efficiency of the geophone node and the rope.

[0069] Exemplarily, the model of the geophone node may be: Z100, Z700, Z3000, Mass, or OBX.

[0070] In the related technology, in the shallow sea OBN (Ocean Botton Node) operation area, only micro-sized operation vessels can be used. Due to the limitation of the available deck area, the existing automatic release node operation equipment cannot be installed, resulting in related work in this type of sea area can only rely on manual work. In order to achieve the set operating speed (1.5m / s), 8 to 9 people are required, who are mainly responsible for the transmission, hanging and release of the cable, which has high labor intensity, high operation risk and high operation cost.

[0071] By setting the hooking position and the hooking device 30 provided by the present invention, the node only needs to be manually placed in the righting chute during operation, which reduces the operation risk and labor intensity. While maintaining the operating speed at (1.5m / s), the number of personnel can be reduced to 30% of the original.

[0072] In addition, the above-mentioned hooking device 100 provided by the present invention may also have the following additional technical features:

The hanging tube 210 is installed on the second transmission device 20 (such as a rope) through the sliding portion 212. When the second transmission device 20 is transported, the sliding portion 212 drives the mounting portion 214 to move in the second direction along with the second transmission device 20. The mounting portion 214 is arranged below the sliding portion 212 to facilitate the mounting with the node. The mounting portion 214 has an annular through hole, and the node can pass through the through hole to complete the mounting with the hanging tube 210.

[0075] Further, the first transmission device 10 includes a first main body 102, a first transmission channel 104, and a first alignment device 106. Among them, the first transmission channel 104 on the first main body 102 is in rolling cooperation with the node to transport the manually pushed node to the hanging position. The hanging position is provided on the first main body 102 and at the end of the first transmission channel 104. The node waits for hanging at the hanging position; the first transmission channel 104 is provided in the first main body 102 for transporting the node, and the end of the first transmission channel 104 is the hanging position; the first alignment device 106 is provided on the first main body 102 and is located at the hanging position. The first alignment device 106 includes a pulley. When the node is at the hanging position, at least part of the first alignment device 106 is located above the node.

[0076] Specifically, as Figure 5 shown, the first alignment device 106 is used to align the hook 308 provided on the node during the movement of the node towards the hanging position, so that the hook 308 is at a 90° angle. By providing the first alignment device 106, the hanging connection between the hanging pipe 210 and the hook 308 can be quickly realized, thereby improving the hanging connection efficiency between the seismic detector node and the rope, and further enabling the sailing speed of the node ship.

[0077] In some embodiments, optionally, the second transmission device 20 includes a second upper main body. The second upper main body 202 includes a door body. The door body is close to the side of the first transmission channel where the first alignment device is provided. The door body is used to carry the transport channel of the hanging pipe; the second lower main body 204 is connected to the door body and the first main body, and is arranged in parallel with the second upper main body, and is used to carry the first main body and support the door body.

[0079] Further, the second lower main body 204 is connected to the door body 108 and the first main body 102, that is, both the door body 108 and the first main body 102 are located above the second lower main body. The second lower main body is also arranged in parallel with the second upper main body and intersects with the first main body 102. The second lower main body is used to carry the first main body 102. Through the second upper main body and the second lower main body, a stable structure is established, effectively connecting the first transmission device 10 and the second transmission device 20, which helps to quickly realize the hanging connection between the hanging pipe 210 and the hook 308.

[0080] In some embodiments, optionally, the second transmission device 20 further includes: a rope guide tube 2024 connected to the door body 108, the rope guide tube 2024 is an arc-shaped through groove, which is used to correct the transportation direction of the hanging tube so that the hanging part is aligned with the hanging device.

[0081] In this embodiment, the second transmission device 20 further includes a rope guide tube 2024, which is provided on the door body 108. The rope guide tube 2024 is an arc-shaped through groove, so as to facilitate the passage of the hook tube 210. During operation, the rope will move the hook tube 210 toward the rope guide tube 2024 during the process of being released into the water. The arc-shaped through groove cooperates with the moving hook tube 210, and the hook tube 210 can be gradually straightened until it is facing the through groove, thereby ensuring that the hook tube 210 can run along the through groove of the rope guide tube 2024, so as to be aligned with the hook 308 on the node. By providing the rope guide tube 2024, the hook tube 210 that is shaken by the rope can be straightened, which helps to quickly achieve the hooking of the hook tube 210 and the hook 308.

[0082] Among them, the rope guide tube 2024 is horizontally installed on the door beam of the door body 108, and its central axis is parallel to the central axis of the second lower body, the central axis of the rope guide tube 2024 and the central axis of the first transport channel intersect vertically, and the through groove of the rope guide tube 2024 runs through both ends and the ends of both ends are provided with arc support surfaces.

[0083] Reference Figure 2 and Figure 3 As shown, in some embodiments, optionally, the hanging device 30 includes: a fixed plate 302, connected to the node; a limiting beam 304, connected to the fixed plate 302; a hook limiter 306, arranged on the limiting beam 304, a hook 308, hinged to the hook limiter 306, for hanging with the hanging tube 210 located at the hanging position, the hook 308 and the first straightening device 106 are in rolling cooperation, wherein the hook limiter 306 is used to limit the rolling angle of the hook 308 when the hook 308 and the first straightening device 106 are in rolling cooperation.

[0084] In this embodiment, the hook device 30 includes a fixing plate, a limiting beam 304, a hook 308 and a hook stopper 306. The fixing plate 302 connects the node and the limiting beam 304. The fixing plate 302 provides more contact surfaces for the node to achieve a stable connection to prevent the node from being lost. At the same time, it also provides an installation surface for the hook device 30. The reasonable setting position of the limiting beam 304 can make the hook device 30 connected with the node move more smoothly. The limiting beam 304 is provided with a hook stopper 306, which is hinged to the hook 308. Figure 5 and Figure 6 As shown, before contacting the first straightening device 106, the hook 308 is parallel to the direction of the fixing plate 302, as shown in FIG.Figure 7 As shown, after contacting the first centralizing device 106, the hook 308 is in rolling cooperation with the first centralizing device 106, such as Figure 8 As shown, under the joint restraint of the first centralizing device 106 and the hook limiter 306, the hook 308 is at 90°, that is, perpendicular to the direction where the fixed disk 302 is located. Among them, the hook limiter 306 is used to limit the rolling angle of the hook 308 when the hook 308 and the first centralizing device 106 are in rolling cooperation. Preferably, the rolling angle of the hook 308 is less than or equal to 90°.

[0085] In addition, since a thin cable is currently used to connect the node and the main cable, which is a flexible connection, the laying postures of the node and the seabed are unstable when laid on the seabed. By setting the hook 308, which is hinged to the hook limiter 306, the posture stability after the node is laid on the seabed is improved, avoiding the problem of the current flexible connection between the node and the main cable.

[0086] In some embodiments, optionally, the hook 308 includes: a hanging rod 3082; a hook body 3084, connected to the hanging rod 3082, hinged to the hook limiter 306, and having a first opening between the hanging rod 3082 and the hook body; a lock piece 3086, movably connected to the hook body, for closing the first opening when the mounting portion 214 does not contact the hanging rod 3082 or the mounting portion 214 enters the hanging rod 3082, and opening the first opening when the mounting portion 214 contacts the hanging rod 3082.

[0087] In this embodiment, the hook 308 includes a hanging rod 3082, a hook body, and a lock piece 3086. The hook body 3084 is connected to the hanging rod 3082 and the lock piece. A first opening is formed between the hanging rod 3082 and the hook body. Before the hanging rod 3082 contacts the hanging connection pipe 210, the first opening is closed by the lock piece and is in a normally closed state, such as Figure 9 and Figure 10 As shown, after contacting the hanging connection pipe 210, under the pressure of the hanging connection pipe 210, the lock piece at the first opening moves in the same direction as the hanging connection pipe 210, that is, in the second direction. At this time, the first opening is in an open state, such as Figure 11 As shown, when the hanging connection pipe 210 is completely hung on the hanging rod 3082, the lock piece returns to the position before the hanging rod 3082 contacts the hanging connection pipe 210.

[0088] Among them, the central axis of the hanging rod 3082 of the hook 308 coincides with the central axis of the hanging connection pipe 210, that is, the hanging connection between the hook 308 and the hanging connection pipe 210 is completed, and the hook 308 and the hanging connection pipe 210 are in a hanging connection state.

[0089] In addition, the hook 308 further includes an elastic member 3088. The elastic member 3088 is respectively connected to one end of the hook body and the locking piece. At this time, the other end of the locking piece is connected to the hook body. The elastic member is used to change the closed state or open state of the first opening according to the movement of the locking piece.

[0090] Exemplarily, the elastic member is a spring. The cost of the spring is relatively low, which can reduce the cost of the hanging device.

[0091] Specifically, the hanging pipe 210 continues to move in the through groove of the guide rope pipe 2024 to the hook 308. The moving hanging pipe 210 enters the hanging rod 3082 of the hook 308, abuts against the locking piece and continues to push, completing the unlocking. The hanging pipe 210 continues to advance along the hanging rod 3082 and crosses the locking piece. The elastic member makes the locking piece return to its original position and close, realizing the locking between the hook 308 and the hanging pipe 210, thereby realizing the hanging of the seismic geophone node on the rope.

[0092] Refer to Figure 12 and Figure 13 As shown, in some embodiments, optionally, the first transmission device 10 further includes: a gate 2022, which is arranged on the side of the first transmission guide rail away from the door body 108.

[0093] In this embodiment, the first transmission device 10 further includes a gate 2022. The gate 2022 is located on the side of the first transmission guide rail away from the door body 108, and is arranged opposite to the door body 108. The gate 2022 is located on one side of the hanging position. The gate 2022 is used to, after the hanging pipe 210 and the hook 308 complete the hanging, under the influence of the continuous movement of the rope, the node connected to the hanging pipe 210 pushes open the gate 2022 in the second direction, realizing the release of the node. By providing the gate 2022, it not only restricts the movement of the unhung nodes, but also meets the requirements of automated operation in extremely shallow water areas.

[0094] In some embodiments, optionally, the orientation of the gate 2022 is the same as the second direction.

[0095] In this technical solution, the opening direction of the gate 2022 is the same as the second direction, that is, the same as the moving direction of the hanging pipe 210. As the rope continues to move, the node will push open the gate 2022, thereby finally realizing the release of the seismic geophone node. By opening the gate 2022 in the second direction, the release of the node is realized, meeting the requirements of automated operation in extremely shallow water areas.

[0096] In some embodiments, optionally, the first main body 102 further includes: a limit guide rail 1010, which is arranged on both sides of the first transmission channel 104 and has a sliding fit relationship with the limit beam 304 and the fixed disk 302.

[0097] In this technical solution, the limiting guide rails 1010 are arranged on both sides of the first transmission channel 104, and the limiting guide rails 1010 on both sides are in parallel. The limiting beam 304 and the fixed plate 302 cooperate with the limiting guide rails 1010 to move the node in the first direction and then reach the hanging position, so that the staff only needs to put the node into the first transmission device 10 and push it, which greatly reduces the labor intensity of the staff. Thus, the demand for automated operation in extremely shallow waters is met.

[0098] According to a second aspect of the present invention, a mounting device 300 is provided, which is suitable for mounting the mounting device 100 of the first aspect or any one of the technical solutions of the first aspect. The mounting device comprises: a rope and a plurality of mounting tubes 210, wherein the plurality of mounting tubes 210 are installed on the rope at intervals along the length direction of the rope.

[0099] The mounting device 300 provided by the present invention includes the mounting device of any one of the technical solutions in the first aspect, and thus has all the beneficial effects of any of the above technical solutions, which will not be described in detail here.

[0100] In some specific embodiments, the hooking device for hooking the node, when hooking the hook on the node and the hooking tube on the rope, first, the node is fixed on the hook plate and placed in the righting slide rail (i.e., the first transmission device), the limit beam, the fixed plate and the limit guide rail cooperate with each other to limit the displacement state of the hook plate, and the node is manually pushed to the end of the righting slide. When the node reaches the end of the righting slide, the hook righting wheel (i.e., the first righting device) and the hook limiter jointly constrain the hook to be 90°, and the hook rod axis and the hook tube axis coincide with each other in the hooked state. During the process of releasing the rope into the water, it will move the hook tube in the direction of the guide rope tube. Then, the hook tube contacts the guide rope tube, and the arc righting surface (i.e., the arc-shaped through groove) of the guide rope tube cooperates with the hook tube, thereby ensuring that the hook tube can smoothly enter the hook tube through groove along the arc righting surface. Next, when the hook pipe continues to move in the guide rope pipe groove to the top of the node hook plate (i.e., the node is fixed on the hook plate), the node hook plate hook is straightened to 90° by the hook straightening wheel and the hook limiter, causing the hook pipe axis and the hook rod axis to coincide, and the moving hook pipe pushes open the hook lock plate and continues to push, completing the buckle. Next, the hook pipe that has completed the buckle continues to move, the hook pipe passes over the lock plate, and the lock plate resets under the action of its own elastic force, realizing the lock between the hook and the hook pipe, that is, realizing the connection of the node on the rope. Finally, as the rope continues to move, the node will push open the gate of the straightening slideway, thereby finally achieving the release of the seismic detector node.

[0101] The hooking device provided by the present invention has the following advantages:

[0102] (1) The present invention has a simple structure and a small size, and can be installed on a small and micro node operation ship, meeting the needs of automated operation in extremely shallow waters. At the same time, since the hook and the hanging pipe are hinged, the problem of easy loss and unstable layout caused by conventional soft ropes connecting the hook and the node is eliminated.

[0103] (2) Due to the increase in node release speed, the node ship can sail at high speed, thereby offsetting the interference of ocean currents.

[0104] (3) The staff only needs to put the node into the righting slide and push it to the bottom, which greatly reduces the labor intensity of the staff.

[0105] (4) Due to the significantly high node release speed, the efficiency of seismic exploration operations is greatly improved, greatly saving costs.
