Description

Technical Field

[0001] This invention relates to the field of suspension system technology, specifically to a suspension system for an artificial earthquake air source. Background Technology

[0002] Air-based seismic sources first appeared in the coal mining industry, primarily using high-pressure, high-capacity (5000-6000 in³) single-gun designs. With the development of Earth science, seismologists have used offshore air-based seismic sources in conjunction with seismic stations to conduct experiments exploring the deep crustal and upper mantle structures. In recent years, China has also successively built several land-based air-based seismic source excitation systems. The air-based seismic source is a key component in generating artificial earthquakes. Its working principle is as follows: it stores high-pressure gas; when the pressure reaches the set excitation pressure, it is released instantaneously via a solenoid valve, causing the water body to vibrate. This vibration, combined with the impact of the water body on the ground, produces an artificial earthquake. A single air-based seismic source weighs approximately 150 kg. During operation, it is suspended above a fixed water level. Ensuring that the high-pressure gas pipeline and power / signal lines do not become entangled during operation, and that it is raised above the water surface for easy equipment maintenance, is crucial. Therefore, how to suspend the air-based seismic source in water has become a primary operational requirement.

[0003] This addresses how to suspend the air vibration source within a designated water level area during operation, ensuring that high-pressure air lines and power signal lines do not become entangled, and how to elevate it above the water surface for easy equipment maintenance, thereby improving work efficiency and quality. Summary of the Invention

[0004] To solve the above technical problems, the present invention is implemented through the following technical solution: a suspension system for an artificial earthquake air source, comprising a planar floating platform, a lifting bracket fixedly connected to the top of the planar floating platform, a winch fixedly connected to the top of the lifting bracket, a connecting rope fixedly connected to the drive end of the winch, a movable base fixedly connected to the bottom of the connecting rope, a fixing chain fixedly connected to the side of the movable base, an adjustment device fixedly connected to the bottom of the fixing chain, a fixing device fixedly connected to the bottom of the adjustment device, and an air source fixedly connected to the side of the fixing device, the air source being positioned above the planar floating platform; The fixing device includes a fixed outer shell. An adjusting wheel is rotatably connected to the bottom of the inner wall of the fixed outer shell. An adjusting shaft is rotatably connected to the side of the inner wall of the fixed outer shell. An adjusting rope is slidably connected to the inner wall of the adjusting wheel. The side of the adjusting wheel engages with the side of the adjusting shaft. The top of the adjusting rope is fixedly connected to the bottom of the adjusting device. The side of the fixed outer shell is fixedly connected to the side of the air source. When the air source is activated, air pressure is compressed inside to store gas energy. When the winch is activated, the winch drives the connecting rope to move up and down. The movement of the connecting rope causes the moving base to move up and down for height adjustment. The movement of the seat drives the adjustment device, which in turn moves the adjustment rope. This movement of the rope then moves the adjustment wheel, which in turn moves the fixed housing. The fixed housing then moves the air source, thus moving the air source through the adjustment of the rope. The tilt angle of the air source can be adjusted by combining multiple sets of adjustment ropes, facilitating different excitation angles. Furthermore, the combination of the adjustment wheel and the adjustment shaft ensures that the air source is at the same angular position during adjustment, guaranteeing the uniformity of the excitation state and angle, and facilitating repeatable experiments.

[0005] Preferably, the adjusting wheel includes a rotating base, the top of which has a rotating groove, a fixing ring fixedly connected to the inner side of the rotating base, a limiting groove on the top of the fixing ring, a limiting plate fixedly connected to the inner side of the limiting groove, a rotating worm gear sleeved and fixedly connected to the side of the rotating base, the side of the rotating worm gear meshing with the side of the adjusting shaft, and the rotating base being rotatably connected to the top of the inner wall of the fixed housing through the rotating groove.

[0006] Preferably, the adjusting shaft includes a rotating column, a driving screw groove is provided on the side of the rotating column, an inner rotating hole is provided on the part of the rotating column located on one side of the driving screw groove, a rotating seat is sleeved and fixedly connected to the side of the rotating column located on the inner rotating hole, a rotating groove is provided on the side of the rotating seat, the side of the driving screw groove meshes with the side of the rotating worm gear, and the rotating seat is rotatably connected to the inner wall side of the fixed housing through the rotating groove.

[0007] Preferably, the adjusting rope includes a fixing ring with an embedding groove on its side. A connecting rope is fixedly connected to the side of the fixing ring. The fixing ring is disposed inside the rotating base and slidably connected to the rotating base. The top of the connecting rope is fixedly connected to the bottom of the adjusting device. The connecting rope is driven by the adjusting device, and the fixing ring is embedded into the inside of the fixing ring. It slides along the side of the limiting plate through the embedding groove into the limiting groove. This setting facilitates the fixing of the connecting rope in a fixed position on the inner wall of the fixing ring. The setting of the limiting groove facilitates the division of the fixed position of the internal angle of the fixing ring, thereby facilitating the fixing ring to be locked in the fixed limiting groove during movement. This ensures that the adjusting device moves the connecting rope up and down within the range of motion. Furthermore, the setting of multiple sets of limiting grooves facilitates multi-angle adjustment. The angle is rapidly switched, and during the process of the fixed ring being embedded into the limiting groove, the side of the fixed ring is squeezed under the restriction of the limiting plate, thereby preventing the fixed ring from sliding out inside the limiting groove. When the angle is finely adjusted, the rotating seat is rotated, the rotating seat rotates, the rotating column rotates, the rotating column rotates, the driving screw groove rotates, the driving screw groove rotates, the rotating worm wheel rotates, and the rotating worm wheel rotates, thereby completing the angle adjustment of the fixed ring. After the adjustment is completed, the unidirectional transmission is achieved in the meshing state of the driving screw groove and the rotating worm wheel to prevent the rotating worm wheel from rotating on its own. The setting of the rotating groove facilitates the rotation adjustment of the rotating base inside the fixed shell during active adjustment. The setting of the rotating groove facilitates the rotational engagement with the inner wall side of the fixed shell. The setting of the rotating seat and the inner rotating hole facilitates the rotation of the rotating column to drive the rotating worm wheel for movement adjustment.

[0008] Preferably, the adjustment device includes a winding shaft, a connecting frame fixedly connected to the side of the winding shaft, a drive seat fixedly connected to the end of the winding shaft away from the connecting frame, a brake ring sleeved and fixedly connected to the side of the drive seat, a drive shaft of an adjustment motor fixedly connected to the side of the drive seat, the top of the connecting frame fixedly connected to the bottom of the movable base, the top of the adjustment motor fixedly connected to the bottom of the movable base, and a connecting rope sleeved on the side of the winding shaft and fixedly connected to the side of the winding shaft.

[0009] Preferably, the drive base includes a drive base, a brake strip is rotatably connected to the side of the drive base via a rotating shaft, a reset spring is fixedly connected to the side of the brake strip, the side of the drive base is fixedly connected to the side of the winding shaft, and the side of the drive base away from the winding shaft is fixedly connected to the drive shaft of the adjusting motor. During adjustment, the adjusting motor is started, the drive shaft of the adjusting motor rotates, causing the drive base to rotate, which in turn causes the brake strip to rotate. The brake strip rotates and moves along the inner wall of the brake ring. During this movement, the brake strip rotates under the squeezing action of the brake ring, thereby squeezing and deforming the reset spring. The deformation of the reset spring generates elastic force, causing the brake strip to rotate back. The brake bar is locked inside the brake ring, driving the base to rotate and causing the winding shaft to rotate. The rotation of the winding shaft winds the connecting rope, thus keeping the winding shaft stable after the adjustment motor stops driving after the winding shaft has finished rotating. This allows the connecting frame to be moved by the moving base, and the movement of the connecting frame moves the winding shaft, thereby adjusting the entire air vibration source. By setting multiple sets of adjustment motors, different pitch angles can be achieved by using different winding shaft convolution amounts when adjusting the pitch angle of the air vibration source, thus facilitating air excitation tests at different angles. At the same time, the braking of the brake bar and brake ring ensures that the winding shaft remains fixed when external intervention stops.

[0010] Preferably, the brake ring includes a limiting ring with a brake groove on its inner wall. A return spring is fixedly connected to the side of the limiting ring. A sliding frame is sleeved and slidably connected to the side of the limiting ring. A limiting slide bar is fixedly connected to the inner wall of the sliding frame. The movable end of an electric telescopic rod is fixedly connected to the side of the limiting ring. The fixed end of the electric telescopic rod is fixedly connected to the side of an adjusting motor. The brake bar is disposed inside the brake groove. The side of the return spring contacts the side of the adjusting motor. The brake bar slides along the inner wall of the brake groove and brakes inside the groove. When adjustment is complete and reversal is required... When the electric telescopic rod is activated, its movement causes the limiting ring to move as well. The limiting ring moves along the inner wall of the sliding frame, and during this sliding motion, it is restricted by the limiting slide bar. Simultaneously, the movement of the limiting ring compresses and deforms the return spring, generating elastic force. This elastic force drives the limiting ring to move again, re-engaging it with the side of the drive base. This facilitates the re-engagement of the brake bar, allowing for rewinding around the reel. Consequently, the connecting rope is wound at different amounts on the side of the reel, thus achieving different pitch angle adjustments.

[0011] This invention provides a suspension system for an artificial earthquake air source. It has the following beneficial effects: 1. The suspension system of this artificial earthquake air source includes a fixed outer shell. When the air source is activated, air pressure is compressed inside to store gas energy. Activating a winch moves the connecting rope up and down, which in turn moves the movable base up and down for height adjustment. The movable base then moves the adjustment device, which in turn moves the adjustment rope, which in turn moves the adjustment wheel, which in turn moves the fixed outer shell, and finally, the fixed outer shell moves the air source. Thus, the air source is moved by adjusting the ropes, and the tilt angle of the air source can be adjusted by combining multiple sets of adjustment ropes. This allows for different excitation angles to be achieved. The combination of the adjustment wheel and adjustment shaft ensures that the air source is at the same angular position during adjustment, thus guaranteeing the uniformity of the excitation state and angle, and facilitating repeatable experiments.

[0012] 2. The suspension system of this artificial earthquake air source is equipped with a fixed ring. The connecting rope is driven by the adjustment device. The fixed ring is embedded into the inside of the fixed ring and slides along the side of the limiting plate into the limiting groove through the embedding groove. This design facilitates the fixing of the connecting rope to the inner wall of the fixed ring. The limiting groove facilitates the division of the fixed position of the internal angle of the fixed ring, thus ensuring that the fixed ring is locked in the fixed limiting groove during movement. This allows the connecting rope to be fixed within the range of motion as the adjustment device moves the connecting rope up and down. Furthermore, the multiple sets of limiting grooves facilitate rapid switching between multiple angles during angle adjustment. The fixed ring is also constrained by the limiting plate during the process of embedding into the limiting groove. The side of the device generates pressure, thus preventing the fixed ring from sliding out inside the limiting groove. When making a fine angle adjustment, the rotating seat is rotated, which in turn drives the rotating column to rotate. The rotating column then drives the drive screw groove to rotate, which in turn drives the rotating worm wheel to rotate. The rotating worm wheel then drives the fixed ring to rotate, thus completing the angle adjustment of the fixed ring. After the adjustment is completed, the drive screw groove and the rotating worm wheel are engaged to achieve unidirectional transmission and prevent the rotating worm wheel from rotating on its own. The rotating groove facilitates the rotation adjustment of the rotating base inside the fixed shell during active adjustment. The rotating groove facilitates rotational engagement with the inner wall of the fixed shell. The rotating seat and the inner rotating hole facilitate the rotation of the rotating column to drive the rotating worm wheel for movement and adjustment.

[0013] 3. The suspension system of this artificial earthquake air source is equipped with a reset spring. During adjustment, the adjustment motor is started, and the drive shaft of the adjustment motor rotates, driving the drive base to rotate. The drive base rotates, driving the brake bar to rotate. The brake bar moves along the inner wall of the brake ring. During the movement of the brake bar, it rotates under the squeezing action of the brake ring, thereby squeezing and deforming the reset spring. The deformation of the reset spring generates elastic force, driving the brake bar to rotate, thus locking the brake bar inside the brake ring. The rotation of the drive base drives the winding shaft to rotate, and the rotation of the winding shaft winds the connecting rope. Thus, after the winding shaft has rotated and the adjustment motor stops driving, the winding shaft remains in a stable state. This facilitates the movement of the connecting frame by moving the base, and the movement of the connecting frame drives the movement of the winding shaft, thereby adjusting the entire air source. By setting multiple sets of adjustment motors, different pitch angles can be achieved by different winding shaft convolution amounts when adjusting the pitch angle of the air source, thus facilitating air excitation tests at different angles. At the same time, the braking of the brake bar and the brake ring ensures that the winding shaft remains fixed when external intervention stops.

[0014] 4. The suspension system of this artificial earthquake air source is equipped with a brake bar. The brake bar slides along the inner wall of the brake groove and brakes inside the groove. When adjustment is complete and retraction is needed, the electric telescopic rod is activated. The electric telescopic rod moves, causing the limiting ring to move. The limiting ring moves along the inner wall of the sliding frame. During the sliding process, the limiting ring is restricted by the limiting slide bar, limiting its sliding trajectory. At the same time, the movement of the limiting ring compresses and deforms the return spring, generating elastic force. The elastic force of the return spring drives the limiting ring to move again. The moving limiting ring re-engages with the side of the drive base, thus facilitating the re-braking of the brake bar and the retraction of the winding shaft. This allows the connecting rope to be wound at different amounts on the side of the winding shaft, thereby achieving different pitch angle adjustments. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] For the first embodiment, please refer to... Figures 1-2 The present invention provides a technical solution: a suspension system for an artificial earthquake air source, including a planar floating platform 1, a lifting bracket 2 fixedly connected to the top of the planar floating platform 1, a winch 3 fixedly connected to the top of the lifting bracket 2, a connecting rope 4 fixedly connected to the drive end of the winch 3, a movable base 5 fixedly connected to the bottom of the connecting rope 4, a fixing chain 6 fixedly connected to the side of the movable base 5, an adjustment device 7 fixedly connected to the bottom of the fixing chain 6, a fixing device 8 fixedly connected to the bottom of the adjustment device 7, and an air source 9 fixedly connected to the side of the fixing device 8. The air source 9 is positioned above the planar floating platform 1. The fixing device 8 includes a fixing housing 801. An adjusting wheel 802 is rotatably connected to the bottom of the inner wall of the fixing housing 801. An adjusting shaft 803 is rotatably connected to the side of the inner wall of the fixing housing 801. An adjusting rope 804 is slidably connected to the inner wall of the adjusting wheel 802. The side of the adjusting wheel 802 engages with the side of the adjusting shaft 803. The top of the adjusting rope 804 is fixedly connected to the bottom of the adjusting device 7. The side of the fixing housing 801 is fixedly connected to the side of the air vibration source 9.

[0019] The air source 9 is activated, and the internal air pressure is compressed to store gas energy. The winch 3 is activated, and the winch 3 drives the connecting rope 4 to move up and down. The movement of the connecting rope 4 causes the moving base 5 to move up and down for height adjustment. The movement of the moving base 5 causes the adjustment device 7 to move. The movement of the adjustment device 7 causes the adjustment rope 804 to move. The movement of the adjustment rope 804 causes the adjustment wheel 802 to move. The movement of the adjustment wheel 802 causes the fixed shell 801 to move. The movement of the fixed shell 801 causes the air source 9 to move. Thus, the air source 9 is moved by adjusting the adjustment rope 804. The tilt angle of the air source 9 can be adjusted by combining multiple sets of adjustment ropes 804, so as to achieve different excitation angles. The combination of adjustment wheel 802 and adjustment shaft 803 ensures that the air source 9 is in the same angular position when the adjustment rope 804 is adjusted, so as to ensure the uniformity of the excitation state and angle and facilitate repeated experiments.

[0020] For the second embodiment, please refer to... Figures 1-5 Based on the first embodiment, the present invention provides a technical solution: the adjusting wheel 802 includes a rotating base 8021, a rotating groove 8022 is provided on the top of the rotating base 8021, a fixing ring 8023 is fixedly connected to the inner wall side of the rotating base 8021, a limiting groove 8024 is provided on the top of the fixing ring 8023, a limiting plate 8025 is fixedly connected to the inner wall side of the limiting groove 8024, a rotating worm gear 8026 is sleeved and fixedly connected to the side of the rotating base 8021, the side of the rotating worm gear 8026 meshes with the side of the adjusting shaft 803, and the rotating base 8021 is rotatably connected to the top of the inner wall of the fixed housing 801 through the rotating groove 8022.

[0021] The adjusting shaft 803 includes a rotating column 8031. A drive screw groove 8032 is provided on the side of the rotating column 8031. An inner rotating hole 8033 is provided on the part of the rotating column 8031 ​​located on one side of the drive screw groove 8032. A rotating seat 8034 is sleeved and fixedly connected to the side of the rotating column 8031 ​​located on the inner rotating hole 8033. A rotating groove 8035 is provided on the side of the rotating seat 8034. The side of the drive screw groove 8032 meshes with the side of the rotating worm gear 8026. The rotating seat 8034 is rotatably connected to the inner wall side of the fixed housing 801 through the rotating groove 8035.

[0022] The adjusting rope 804 includes a fixing ring 8041, an embedding groove 8042 is provided on the side of the fixing ring 8041, a connecting rope 8043 is fixedly connected to the side of the fixing ring 8041, the fixing ring 8041 is disposed inside the rotating base 8021 and is slidably connected to the rotating base 8021, and the top of the connecting rope 8043 is fixedly connected to the bottom of the adjusting device 7.

[0023] The connecting rope 8043 is driven by the adjusting device 7. The fixing ring 8041 is embedded into the inside of the fixing ring 8023 and slides into the limiting groove 8024 along the side of the limiting plate 8025 through the embedding groove 8042. This setting facilitates the fixing of the connecting rope 8043 to the inner wall of the fixing ring 8023. The setting of the limiting groove 8024 facilitates the division of the fixed position of the internal angle of the fixing ring 8023, so that the fixing ring 8041 can be locked in the fixed limiting groove 8024 during the movement. This ensures that the adjusting device 7 fixes the connecting rope 8043 within the range of movement. When adjusting the angle, the setting of multiple sets of limiting grooves 8024 facilitates the rapid switching of multiple angles. During the process of the fixing ring 8041 being embedded into the limiting groove 8024, the limiting plate 8025 restricts the side of the fixing ring 8041, thereby preventing the fixing ring 8041 from being squeezed in the limiting position. The inside of the groove 8024 slides out. When making a fine-tuning of the angle, the rotating seat 8034 is rotated. The rotation of the rotating seat 8034 drives the rotating column 8031 ​​to rotate. The rotation of the rotating column 8031 ​​drives the drive screw groove 8032 to rotate. The rotation of the drive screw groove 8032 drives the rotating worm gear 8026 to rotate. The rotation of the rotating worm gear 8026 drives the fixed ring 8023 to rotate, thereby completing the angle adjustment of the fixed ring 8023. After the adjustment is completed, the unidirectional transmission is achieved in the meshing state of the drive screw groove 8032 and the rotating worm gear 8026 to prevent the rotating worm gear 8026 from rotating on its own. The setting of the rotating groove 8022 facilitates the rotation adjustment of the rotating base 8021 inside the fixed shell 801 during active adjustment. The setting of the rotating groove 8035 facilitates the rotational engagement with the inner wall side of the fixed shell 801. The setting of the rotating seat 8034 and the inner rotating hole 8033 facilitates the rotation of the rotating column 8031 ​​to drive the rotating worm gear 8026 for movement adjustment.

[0024] Third embodiment, please refer to Figures 1-7 Based on the second embodiment, the present invention provides a technical solution: the adjustment device 7 includes a winding shaft 701, a connecting frame 702 is fixedly connected to the side of the winding shaft 701, a drive seat 703 is fixedly connected to the end of the winding shaft 701 away from the connecting frame 702, a brake ring 704 is sleeved and fixedly connected to the side of the drive seat 703, a drive shaft of an adjustment motor 705 is fixedly connected to the side of the drive seat 703, the top of the connecting frame 702 is fixedly connected to the bottom of the movable base 5, the top of the adjustment motor 705 is fixedly connected to the bottom of the movable base 5, and a connecting rope 8043 is sleeved on the side of the winding shaft 701 and fixedly connected to the side of the winding shaft 701.

[0025] The drive base 703 includes a drive base 7031. A brake strip 7032 is rotatably connected to the side of the drive base 7031 via a rotating shaft. A reset spring 7033 is fixedly connected to the side of the brake strip 7032. The side of the drive base 7031 is fixedly connected to the side of the winding shaft 701. The side of the drive base 7031 away from the winding shaft 701 is fixedly connected to the drive shaft of the adjusting motor 705.

[0026] During adjustment, the adjustment motor 705 is started. The drive shaft of the adjustment motor 705 rotates, causing the drive base 7031 to rotate. The rotation of the drive base 7031 causes the brake strip 7032 to rotate. The brake strip 7032 rotates and moves along the inner wall of the brake ring 704. During the movement of the brake strip 7032, it rotates under the squeezing action of the brake ring 704, thereby squeezing and deforming the reset spring 7033. The deformation of the reset spring 7033 generates elastic force, causing the brake strip 7032 to rotate, thus causing the brake strip 7032 to be stuck inside the brake ring 704. The rotation of the drive base 7031 causes the winding shaft 701 to rotate, and the rotation of the winding shaft 701 affects the connecting rope 804. 3. The winding is performed so that after the winding shaft 701 has rotated and the adjustment motor 705 stops driving, the winding shaft 701 remains stable. This makes it easy to move the connecting frame 702 by moving the base 5. The movement of the connecting frame 702 moves the winding shaft 701, which in turn moves the air source 9 as a whole, thus adjusting the pitch angle of the air source 9. By setting multiple sets of adjustment motors 705, different pitch angles can be achieved by different winding amounts of the winding shaft 701 when adjusting the pitch angle of the air source 9. This makes it easy to achieve air excitation tests at different angles. At the same time, the braking of the brake strip 7032 and the brake ring 704 makes it easy for the winding shaft 701 to remain fixed when there is no external intervention.

[0027] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the brake ring 704 includes a limiting ring 7041, the inner wall of the limiting ring 7041 is provided with a brake groove 7042, a return spring 7043 is fixedly connected to the side of the limiting ring 7041, a sliding frame 7044 is sleeved and slidably connected to the side of the limiting ring 7041, a limiting slide bar 7045 is fixedly connected to the inner wall side of the sliding frame 7044, the movable end of an electric telescopic rod 7046 is fixedly connected to the side of the limiting ring 7041, the fixed end of the electric telescopic rod 7046 is fixedly connected to the side of an adjusting motor 705, a brake bar 7032 is disposed inside the brake groove 7042, and the side of the return spring 7043 contacts the side of the adjusting motor 705.

[0028] Brake bar 7032 slides along the inner wall of brake groove 7042 and brakes inside brake groove 7042. When adjustment is complete and retraction is required, electric telescopic rod 7046 is activated. The movement of electric telescopic rod 7046 drives limit ring 7041 to move. Limit ring 7041 moves along the inner wall of sliding frame 7044. During the sliding process of limit ring 7041 along the inner wall of sliding frame 7044, limit ring 7041 slides along a trajectory limited by limit slider 7045. The limiting ring 7041 moves while compressing and deforming the return spring 7043 to generate elastic force. The elastic force of the return spring 7043 drives the limiting ring 7041 to move. The limiting ring 7041 moves and re-engages with the side of the drive base 7031, which facilitates the restoration of braking of the brake bar 7032. This facilitates the return of the winding shaft 701, so that the connecting rope 8043 is wound with different amounts on the side of the winding shaft 701, thereby achieving different pitch angle adjustments.

[0029] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
