Description

Technical Field

[0001] This application relates to the field of seismic source excitation source structure technology, and in particular to a gas explosion vector seismic source excitation source structure. Background Technology

[0002] A gas explosion vector source is a device that introduces methane, oxygen, or other gases into a cavity and detonates them with an electric spark to generate shock waves. It can be used in marine or terrestrial applications and requires specialized detonation equipment.

[0003] Current vector gas explosion devices generally include a gas explosion mechanism connected to a gas storage mechanism, with an adjustment mechanism between them. The adjustment mechanism includes a primary gas storage tank and a secondary gas storage tank, connected by a gas pipeline. The secondary gas storage tank is connected to the gas explosion mechanism via a second gas pipeline. A pressure regulating valve is connected to the first gas pipeline, and a solenoid valve is connected to the second gas pipeline. This invention allows for adjustment of the pressure in the gas storage mechanism via the adjustment mechanism, making the height of the water jet ejected by the gas explosion mechanism adjustable.

[0004] Regarding the aforementioned issues, the existing gas explosion vector vibration source excitation source structure cannot control the air intake speed of the tank during operation, which reduces the practicality of the gas explosion vector vibration source excitation source structure. Utility Model Content

[0005] Therefore, it is necessary to provide a gas explosion vector vibration source excitation source structure that can regulate the air intake speed of the tank and improve the practicality of the gas explosion vector vibration source excitation source structure.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: A gas explosion vector vibration source excitation source structure includes: A tank body, with an air inlet pipe provided at one end of the tank body; An adjustment structure is located inside the air intake pipe. The adjustment structure includes a connecting plate and an adjustment plate that are rotatably connected. The connecting plate is fixed to the inner wall of the air intake pipe. The adjustment plate is located inside the connecting plate. The connecting plate has an arc-shaped hole that communicates with the inside of the tank. The connecting plate also has an arc-shaped groove that communicates with the arc-shaped hole. The adjustment plate rotates within the arc-shaped hole so that the adjustment plate closes part of the connection position between the arc-shaped groove and the arc-shaped hole. A drive assembly is mounted on a connecting plate, and the movable end of the drive assembly is connected to the adjusting plate to drive the adjusting plate to move within the arc-shaped hole.

[0007] It is understandable that the arc-shaped groove connecting the interior of the tank with the outside world via the arc-shaped hole, and the adjustment plate located inside the arc-shaped groove rotating inside the groove, allows the arc-shaped plate to close the connection between the arc-shaped hole and the arc-shaped groove, thereby adjusting the area of ​​the connection opening between the arc-shaped hole and the arc-shaped groove, and further adjusting the air intake speed inside the tank through the arc-shaped hole. By setting up the adjustment structure, the air intake speed of the tank can be automatically controlled when the gas explosion vector vibration source excitation source structure is in operation, thus improving the practicality of the gas explosion vector vibration source excitation source structure.

[0008] In one embodiment, the arc-shaped hole is opened along the circumference of the connecting plate, and the length of the arc-shaped hole along the circumference of the connecting plate is not greater than the length of the adjusting plate along the circumference of the connecting plate. The adjusting part can completely cover the arc-shaped hole.

[0009] In one embodiment, a flow guide groove is provided on the side of the connecting plate away from the inside of the tank, and one end of the flow guide groove is connected to the arc-shaped groove.

[0010] In one embodiment, the guide groove is opened radially along the connecting disk, and multiple guide grooves are opened equidistantly along the circumference of the connecting disk.

[0011] In one embodiment, the drive assembly includes a gear ring and a drive gear, the gear ring and the drive gear meshing, the gear ring being sleeved on the outside of the adjusting plate and fixedly connected to the adjusting plate, and a drive member being provided on one side of the drive gear, the drive member driving the drive gear to rotate.

[0012] In one embodiment, a sealing strip is provided on the side wall of the connecting plate near the adjusting plate, one end of the sealing strip is in contact with the adjusting plate, and the other end of the sealing strip is in contact with the connecting plate.

[0013] In one embodiment, the outer wall of the air intake pipe is provided with a fixing seat, the fixing seat is fixedly connected to the outer wall of the air intake pipe, a rotating shaft is rotatably passed through the fixing seat, a connecting plate is fixedly connected to the arc surface of the rotating shaft, and a sealing plate is fixedly connected to one side of the connecting plate.

[0014] In one embodiment, a rubber disc is fixedly connected to one side of the sealing plate, and the rubber disc is adapted to the size of the inner wall of the air intake pipe.

[0015] In one embodiment, the rotating shaft is coaxially fixedly connected to a turntable, the turntable is eccentrically rotatably connected to a connecting rod away from the side wall of the rotating shaft, the connecting rod is rotatably connected to a partition plate away from the turntable, and a lead screw is threadedly connected to the partition plate, the lead screw being arranged along the height direction.

[0016] In one embodiment, a support plate is rotatably connected to the lead screw, and the support plate is fixed to the air intake pipe.

[0017] Compared with existing technologies, a gas explosion vector vibration source excitation structure connects the interior of the tank with an arc-shaped groove through an arc-shaped hole. An adjustment plate located inside the arc-shaped groove rotates within the groove, allowing the plate to close the connection between the arc-shaped hole and the groove. This adjusts the area of ​​the opening between the arc-shaped hole and the groove, further regulating the air intake speed through the arc-shaped hole inside the tank. By incorporating this adjustment structure, the gas explosion vector vibration source excitation structure can automatically regulate the air intake speed of the tank during operation, improving its practicality.

[0026] A gas explosion vector source is a device that introduces methane, oxygen, or other gases into a cavity and detonates them with an electric spark to generate shock waves. It can be used in marine or terrestrial applications and requires specialized detonation equipment.

[0027] Current vector gas explosion devices generally include a gas explosion mechanism connected to a gas storage mechanism, with an adjustment mechanism between them. The adjustment mechanism includes a primary gas storage tank and a secondary gas storage tank, connected by a gas pipeline. The secondary gas storage tank is connected to the gas explosion mechanism via a second gas pipeline. A pressure regulating valve is connected to the first gas pipeline, and a solenoid valve is connected to the second gas pipeline. This invention allows for adjustment of the pressure in the gas storage mechanism via the adjustment mechanism, making the height of the water jet ejected by the gas explosion mechanism adjustable.

[0028] Regarding the aforementioned issues, the existing gas explosion vector vibration source excitation source structure cannot control the air intake speed of the tank during operation, which reduces the practicality of the gas explosion vector vibration source excitation source structure.

[0029] Therefore, it is necessary to provide a gas explosion vector vibration source excitation source structure that can regulate the air intake speed of the tank and improve the practicality of the gas explosion vector vibration source excitation source structure.

[0030] Please see Figures 1 to 6 This application provides a gas explosion vector vibration source excitation source structure, including a tank 1, an air inlet pipe 2 is provided at the top of the tank 1, the air inlet pipe 2 is fixedly connected to the tank 1, and the interior of the air inlet pipe 2 is in relative communication with the interior of the tank 1, so that gas can enter the interior of the tank 1 through the air inlet pipe 2.

[0031] Reference Figure 2 , Figure 3 An adjustment structure 3 is provided inside the air intake pipe 2. The adjustment structure 3 is located at the connection position between the air intake pipe 2 and the tank 1. The adjustment structure 3 can adjust the connection area between the air intake pipe 2 and the tank 1, thereby adjusting the rate at which gas enters the tank 1.

[0032] In some embodiments, the adjustment structure 3 includes a connecting plate 301 and an adjustment plate 304. The connecting plate 301 is fixedly connected to the inner wall of the air intake pipe 2 and is coaxially arranged with the air intake pipe 2. An arc-shaped groove 302 is provided on the inner side wall of the connecting plate 301. The arc-shaped groove 302 is coaxially arranged with the connecting plate 301 and has an annular structure.

[0033] The side wall of the connecting plate 301 is also provided with an arc-shaped hole 303. One end of the arc-shaped hole 303 is connected to the inside of the tank 1, and the other end of the arc-shaped hole 303 is connected to the arc-shaped groove 302, so that the inside of the tank 1 is connected to the arc-shaped groove 302 through the arc-shaped hole 303.

[0034] The adjusting plate 304 is located inside the connecting plate relative to the arc groove 302, and one end wall of the adjusting plate 304 abuts against the inner side wall of the arc groove 302, and the other end wall of the adjusting plate 304 abuts against the side wall of the arc hole 303. The adjusting plate 304 slides against the inner wall of the arc groove 302, and the adjusting plate 304 is slidably connected to the inner wall of the arc hole 303.

[0035] In a specific embodiment, the adjusting plate 304 is an arc-shaped structure adapted to the arc-shaped groove 302, and the circumferential length of the adjusting plate 304 along the connecting plate 301 is not less than the circumferential length of the arc-shaped hole 303 along the connecting plate 301, so that the adjusting plate 304 can completely seal the sidewall of the arc-shaped hole 303. By rotating the adjusting plate 304 within the arc-shaped groove 302, the adjusting plate 304 gradually overlaps with the arc-shaped hole 303, thereby sealing the connection between the arc-shaped hole 303 and the arc-shaped groove 302, thus blocking the communication between the gas inside the tank 1 and the arc-shaped groove 302, and thus controlling the intake rate.

[0036] Reference Figure 3 , Figure 4 A gear ring 305 is coaxially mounted on the outer wall of the adjustment plate 304, and is fixedly connected to the outer wall of the adjustment plate 304. A servo motor 306 is fixedly connected to the upper surface of the connecting plate 301, and a gear 307 is fixedly connected to the output end of the servo motor 306. The gear 307 meshes with the gear ring 305. This causes the servo motor 306 to drive the gear 307 to rotate, which in turn drives the gear ring 305 to rotate. The gear ring 305 then drives the adjustment plate 304 to rotate inside the arc-shaped groove 302, thus shielding the arc-shaped hole 303.

[0037] By setting the adjustment structure 3, the air intake speed of the tank 1 can be automatically controlled during operation of the gas explosion vector vibration source excitation source structure, thereby improving the applicability of the gas explosion vector vibration source excitation source structure. A sealing strip 309 is fixedly connected to the lower surface of the connecting plate 301, and the upper surface of the sealing strip 309 is in contact with the lower surface of the adjustment plate 304. The sealing strip 309 can block the tiny gaps between the adjustment plate 304 and the connecting plate 301, thereby improving the sealing performance between the adjustment plate 304 and the connecting plate 301.

[0038] The upper surface of the connecting plate 301 has a guide groove 310, which is arranged radially along the connecting plate 301. Multiple guide grooves 310 are equidistantly arranged circumferentially along the connecting plate 301, and are connected to the arc-shaped hole 303. By providing the guide groove 310, gas can pass through the arc-shaped hole 303 more smoothly. A protective cover 308 is fitted over the servo motor 306, and the protective cover 308 is fixedly connected to the upper surface of the connecting plate 301. The protective cover 308 can seal and cover the servo motor 306, thereby improving the service life of the protective cover 308.

[0039] Reference Figure 2 , Figure 5 An auxiliary structure 4 is also provided on the side wall of the intake pipe 2. The auxiliary structure 4 is used to seal the opening of the intake pipe 2. In a specific embodiment, the auxiliary structure 4 includes a fixing seat 401, which is fixedly connected to the outer wall of the intake pipe 2. A rotating shaft 402 is rotatably passed through the inner wall of the fixing seat 401. The rotating shaft 402 is horizontally arranged. A connecting plate 403 is fixedly connected to the arc surface of the rotating shaft 402. A sealing plate 404 is fixedly connected to the side of the connecting plate 403 opposite to the rotating shaft 402. A rubber disc 405 is fixedly connected to the side of the sealing plate 404 opposite to the connecting plate 403. The rubber disc 405 is adapted to the size of the inner wall of the intake pipe 2.

[0040] By setting the auxiliary structure 4, the rubber disc 405 can be easily adjusted to seal the air intake pipe 2, eliminating the need for an additional plastic plug to seal the air intake pipe 2, thus improving the integration level of the gas explosion vector vibration source excitation source structure.

[0041] Reference Figure 5 , Figure 6 To facilitate the rotation of the auxiliary structure 4 and seal the end of the intake pipe 2, a turntable 406 is fixedly connected to one side of the rotating shaft 402. A connecting rod 407 is rotatably connected to the eccentric position of the turntable 406 away from the rotating shaft 402. A support plate 410 is fixedly connected to the outer wall of the intake pipe 2. A lead screw 409 is rotatably connected to the upper surface of the support plate 410. A partition plate 408 is threadedly connected to the arc surface of the lead screw 409. One side of the partition plate 408 is rotatably connected to one end of the connecting rod 407.

[0042] When it is necessary to control the rotation of the rotating shaft 402, first rotate the lead screw 409 to drive the partition 408, causing the partition 408 to move along the arc surface of the lead screw 409. The partition 408 drives the connecting rod 407 to rotate, the connecting rod 407 drives the turntable 406 to rotate, and the turntable 406 drives the rotating shaft 402 to rotate. By setting the above structure, the effect of conveniently controlling the rotation of the rotating shaft 402 is achieved. Several rotating plates 411 are fixedly connected to the upper end of the lead screw 409, and the rotating plates 411 are evenly distributed at one end of the lead screw 409. Rotating the rotating plates 411 can drive the lead screw 409 to rotate, achieving the effect of conveniently controlling the rotation of the lead screw 409.

[0043] When using the gas explosion vector seismic source excitation source tank 1, methane, oxygen, or other gases are first introduced into the tank 1 through the air inlet pipe 2, and then ignited by an electric spark to generate a shock wave. It can be used in marine or terrestrial applications and requires specialized detonation equipment. This type of source is superior to solid explosives in shock wave transmission, allowing control of the cavity rupture direction and thus the direction of the main energy propagation of the shock wave. It is one of the non-explosive seismic sources with higher seismic energy. When the air intake speed needs to be adjusted, the servo motor 306 is first started to drive the gear 307 to rotate. The gear 307 drives the gear ring 305 to rotate, and the gear ring 305 drives the adjusting plate 304 to adjust the speed. 304 slides along the inner wall of the arc-shaped groove 302 and the arc-shaped hole 303. Then, the rotation of the adjusting plate 304 can adjust the size of the opening of the arc-shaped hole 303, thereby controlling the intake speed. The sealing strip 309 can block the tiny gap between the adjusting plate 304 and the connecting plate 301, thereby improving the sealing between the adjusting plate 304 and the connecting plate 301. In addition, by setting the guide groove 310, the gas can pass through the arc-shaped hole 303 more smoothly. Finally, the protective cover 308 can seal and cover the servo motor 306, thereby improving the service life of the protective cover 308.

[0044] When it is necessary to adjust the rubber disc 405 to seal the air intake pipe 2, first rotate the rotating plate 411 to drive the lead screw 409 to rotate. The lead screw 409 drives the partition plate 408, causing the partition plate 408 to move along the arc surface of the lead screw 409. The partition plate 408 drives the connecting rod 407 to rotate. The connecting rod 407 drives the turntable 406 to rotate. The turntable 406 drives the rotating shaft 402, causing the rotating shaft 402 to rotate along the inner wall of the fixed seat 401. The rotating shaft 402 drives the connecting plate 403, and the connecting plate 403 drives the rubber disc 405. When the rubber disc 405 blocks the air intake of the air intake pipe 2, the rotation of the lead screw 409 can be stopped. At this time, the process is complete. The paired intake pipes 2 are sealed. When it is necessary to open the rubber disc 405, simply rotate the rotating plate 411 in the opposite direction to drive the lead screw 409 to rotate in the opposite direction. The lead screw 409 drives the partition 408, causing the partition 408 to move along the arc surface of the lead screw 409. The partition 408 drives the connecting rod 407 to rotate. The connecting rod 407 drives the turntable 406 to rotate. The turntable 406 drives the rotating shaft 402, causing the rotating shaft 402 to rotate along the inner wall of the fixed seat 401. The rotating shaft 402 drives the connecting plate 403, and the connecting plate 403 drives the rubber disc 405. When the rubber disc 405 separates from the inner wall of the intake pipe 2, the rubber disc 405 can be opened.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
