Description

Technical Field

[0001] This utility model relates to the field of underwater blasting technology, and in particular to an anti-buoyancy positioning device for underwater blasting explosive charges. Background Technology

[0002] Underwater blasting refers to the blasting technology that uses the shock waves, water hammer waves, and blasting stress generated by the explosion of explosives in underwater or water-contaminated media to break target objects or rock masses. It is widely used in water conservancy projects, waterway dredging, port construction, underwater reef removal, and shipwreck salvage.

[0003] In existing technologies, when placing underwater explosive charges, a counterweight is usually suspended at the bottom of the explosive charge. The counterweight and the explosive charge are connected by a flexible or semi-rigid suspension. The principle of preventing buoyancy is to rely on the gravity of the counterweight to pull the explosive charge to counteract the buoyancy. However, in underwater currents, the counterweight is prone to swinging, which weakens the pulling effect and may cause the position of the explosive charge to shift. This may result in a deviation between the actual blasting position and the designed position, affecting the blasting effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an underwater explosive charge anti-buoyancy positioning device.

[0005] This utility model is achieved by the following technical solution: an underwater explosive charge anti-buoyancy positioning device, including a placement bucket, an anti-buoyancy component on the top of the placement bucket, and a fixing component in the middle of the placement bucket; The anti-floating component includes a pin rod, which is slidably connected to the placement bucket. A fixing plate is slidably connected to the outer wall of the pin rod, and a toothed ring is fixedly connected to the outer wall of the fixing plate. The toothed ring is rotatably connected to the inner wall of the placement bucket, and a gear is meshed with the gear. A rotating rod is fixedly connected inside the gear, and the rotating rod is rotatably connected to the placement bucket. A baffle is fixedly connected to the outer wall of the end of the rotating rod away from the gear.

[0006] Through the above technical solution, the baffle blocks the placement opening at the top of the placement barrel, preventing the explosive charge from floating due to buoyancy, and also preventing the explosive charge from swaying in the water due to undercurrents, ensuring that the explosive charge is in the designed position and improving the blasting effect. At this time, the pin is slid inside the placement barrel and the fixing plate, thereby locking the fixing plate and preventing the baffle from shifting due to undercurrents and causing the blocking to fail. The placement barrel also provides physical protection for the explosive charge, preventing the explosive charge from swaying in the water and scratching the hole wall.

[0007] As a further improvement to the above solution, the fixing component includes a sliding groove, which is formed inside the placement barrel, and a sliding piece is slidably connected to the outer wall of the sliding groove.

[0008] As a further improvement to the above solution, a spring is fixedly connected to the outer wall of the sliding plate, and a connecting rod is fixedly connected to the end of the sliding plate away from the spring.

[0009] Through the above technical solution, the reverse elastic force of the spring continuously pushes the claw block to fit tightly against the inner wall of the blast hole. When the placement bucket is subjected to buoyancy and tends to float upward, the barbs of the claw block physically engage with the hole wall, accurately locking the predetermined position of the placement bucket and further preventing the overall displacement of the placement bucket.

[0010] As a further improvement to the above solution, the connecting rod is slidably connected inside the placement bucket, and a sliding block is fixedly connected to the end of the connecting rod away from the sliding piece.

[0011] As a further improvement to the above solution, a first fixing rod is fixedly connected inside the sliding block, a first connecting plate is rotatably connected to the outer wall of the first fixing rod, and a second fixing rod is rotatably connected to the end of the first connecting plate away from the first fixing rod.

[0012] As a further improvement to the above solution, a claw block is fixedly connected to the outer wall of the second fixing rod, and a first support rod is fixedly connected to the inner end of the claw block away from the second fixing rod. A second connecting plate is rotatably connected to the outer wall of the first support rod.

[0013] As a further improvement to the above solution, a second support rod is rotatably connected to the end of the second connecting plate away from the first support rod, and the second support rod is fixedly connected to the outer wall of the placement bucket.

[0014] Through the above technical solution, the claw block drives the second fixed rod and the first support rod to move synchronously, and the first support rod maintains the stability of the claw block's movement trajectory under the limiting action of the second connecting plate and the first support rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention involves a person pushing a fixing plate, which rotates around a placement bucket. The fixing plate drives a gear ring to rotate on the inner wall of the placement bucket. The gear ring meshes synchronously with several gears. When the gears rotate, they drive a rotating rod to rotate synchronously. At this time, the rotating rod drives a baffle plate to move. The baffle plate rotates around the rotating rod and blocks the placement opening at the top of the placement bucket, preventing the explosive charge from floating due to buoyancy. It also prevents the explosive charge from swaying in the water due to undercurrents, ensuring that the explosive charge is in the designed position and improving the blasting effect. At this time, a pin is placed inside the placement bucket and the fixing plate to lock the fixing plate, preventing the baffle plate from shifting due to undercurrents and causing the blocking to fail. The placement bucket also provides physical protection for the explosive charge, preventing it from swaying in the water and scratching the hole wall.

[0016] This invention utilizes the barbed teeth on the outer wall of the claw block to create a pressing contact with the inner wall of the blast hole. The claw block drives the second fixed rod and the first support rod to move synchronously. The first support rod maintains a stable trajectory under the limiting effect of the second connecting plate and the second support rod. At the same time, the first connecting plate rotates synchronously around the first and second fixed rods. The first fixed rod pushes the connecting rod to move through the sliding block. The connecting rod drives the sliding plate to slide along the groove and compress the spring. The reverse elastic force of the spring continuously pushes the claw block to fit tightly against the inner wall of the blast hole. When the placement bucket tends to float due to buoyancy, the barbed teeth of the claw block form a physical engagement with the hole wall, accurately locking the predetermined position of the placement bucket and further preventing the overall displacement of the placement bucket. At the same time, the spring and the claw block can adapt to different hole walls, eliminating the need for manual locking and reducing the complexity of operation. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0020] Please combine Figures 1-6This embodiment provides an underwater explosive charge anti-buoyancy positioning device, including a placement bucket 1, an anti-buoyancy component 2 on the top of the placement bucket 1, and a fixing component 3 in the middle of the placement bucket 1; The anti-floating component 2 includes a pin 201, which is slidably connected to the placement bucket 1. A fixing plate 202 is slidably connected to the outer wall of the pin 201. A toothed ring 203 is fixedly connected to the outer wall of the fixing plate 202. The toothed ring 203 is rotatably connected to the inner wall of the placement bucket 1. A gear 204 is meshed with the toothed ring 203. A rotating rod 205 is fixedly connected inside the gear 204. The rotating rod 205 is rotatably connected to the placement bucket 1. A baffle 206 is fixedly connected to the outer wall of the end of the rotating rod 205 away from the gear 204.

[0021] Personnel push the fixing plate 202, which rotates around the placement bucket 1. The fixing plate 202 drives the gear ring 203 to rotate on the inner wall of the placement bucket 1. At this time, the gear ring 203 meshes synchronously with several gears 204. When the gears 204 rotate, they drive the rotating rod 205 to rotate synchronously. At this time, the rotating rod 205 drives the baffle 206 to move. The baffle 206 rotates around the rotating rod 205. The baffle 206 blocks the placement opening at the top of the placement bucket 1 to prevent the explosive charge from floating due to buoyancy. At the same time, it prevents the explosive charge from swaying in the water due to the undercurrent, ensuring that the explosive charge is in the designed position and improving the blasting effect. At this time, the pin 201 is slid inside the placement bucket 1 and the fixing plate 202 to lock the fixing plate 202, preventing the baffle 206 from shifting and failing to block due to the undercurrent. The placement bucket 1 also provides physical protection for the explosive charge to prevent it from swaying in the water and scratching the hole wall.

[0022] Specifically, the fixing component 3 includes a slide 301, which is opened inside the placement barrel 1, and a sliding piece 302 is slidably connected to the outer wall of the slide 301.

[0023] Specifically, a spring 303 is fixedly connected to the outer wall of the sliding plate 302, and a connecting rod 304 is fixedly connected to the end of the sliding plate 302 away from the spring 303.

[0024] Specifically, the connecting rod 304 is slidably connected inside the placement bucket 1, and a sliding block 305 is fixedly connected to the end of the connecting rod 304 away from the sliding piece 302.

[0025] Specifically, a first fixing rod 306 is fixedly connected inside the sliding block 305, a first connecting plate 307 is rotatably connected to the outer wall of the first fixing rod 306, and a second fixing rod 308 is rotatably connected to the end of the first connecting plate 307 away from the first fixing rod 306.

[0026] Specifically, a claw block 309 is fixedly connected to the outer wall of the second fixed rod 308, and a first support rod 310 is fixedly connected to the inner end of the claw block 309 away from the second fixed rod 308. A second connecting plate 311 is rotatably connected to the outer wall of the first support rod 310.

[0027] Specifically, the second connecting plate 311 is rotatably connected to the end away from the first support rod 310 by a second support rod 312, and the second support rod 312 is fixedly connected to the outer wall of the placement bucket 1.

[0028] Due to the barbed tooth structure on its outer wall, the claw block 309 makes squeezing contact with the inner wall of the blast hole. The claw block 309 drives the second fixed rod 308 and the first support rod 310 to move synchronously. The first support rod 310 maintains a stable movement trajectory under the limiting action of the second connecting plate 311 and the second support rod 312. At the same time, the first connecting plate 307 rotates synchronously around the first fixed rod 306 and the second fixed rod 308. The first fixed rod 306 pushes the connecting rod 304 to move through the sliding block 305. The connecting rod 304 drives the sliding piece 302 to slide along the slide groove 301 and squeeze the spring 303. The reverse elastic force of the spring 303 continuously pushes the claw block 309 to fit tightly against the inner wall of the blast hole. When the placement bucket 1 is buoyed and tends to float, the barbed teeth of the claw block 309 form a physical engagement with the hole wall, accurately locking the predetermined position of the placement bucket 1, further preventing the overall displacement of the placement bucket 1. At the same time, the spring 303 and the claw block 309 can be used to adapt to different hole walls without the need for manual locking, reducing the complexity of operation.

[0029] The implementation principle of the underwater explosive charge anti-buoyancy positioning device in this embodiment is as follows: The operator first places the explosive charge into the placement bucket 1, then places the placement bucket 1 into the blast hole. The operator pushes the fixing plate 202, which rotates around the placement bucket 1. The fixing plate 202 drives the gear ring 203 to rotate on the inner wall of the placement bucket 1. At this time, the gear ring 203 meshes synchronously with several gears 204. When the gears 204 rotate, they drive the rotating rod 205 to rotate synchronously. At this time, the rotating rod 205 drives the baffle 206 to move. 6. Rotating with the rotating rod 205 as the center, the baffle 206 blocks the placement opening at the top of the placement barrel 1, preventing the explosive charge from floating due to buoyancy and preventing it from swaying in the water due to undercurrents, ensuring the explosive charge is in the designed position and improving the blasting effect. At this time, the pin 201 is placed inside the placement barrel 1 and the fixing plate 202, thereby locking the fixing plate 202 and preventing the baffle 206 from shifting and failing to block due to undercurrent scouring. The placement barrel 1 also provides physical protection for the explosive charge, preventing it from floating in the water. The shaking caused scratches on the borehole wall. When the operator lowered the placement bucket 1 into the blast hole, the claw block 309, due to the barbed structure on its outer wall, made squeezing contact with the inner wall of the blast hole. The claw block 309 drove the second fixed rod 308 and the first support rod 310 to move synchronously. The first support rod 310 maintained a stable movement trajectory under the limiting action of the second connecting plate 311 and the second support rod 312. At the same time, the first connecting plate 307 rotated synchronously around the first fixed rod 306 and the second fixed rod 308. The first fixed rod 306 was pushed by the sliding block 305. The moving connecting rod 304 is displaced, and the connecting rod 304 drives the sliding plate 302 to slide along the sliding groove 301 and squeeze the spring 303. The reverse elastic force of the spring 303 continuously pushes the claw block 309 to fit tightly against the inner wall of the blast hole. When the placement barrel 1 is subjected to buoyancy and has an upward tendency, the barbs of the claw block 309 form a physical engagement with the hole wall, accurately locking the predetermined position of the placement barrel 1, further preventing the overall displacement of the placement barrel 1. At the same time, the spring 303 and the claw block 309 can be adapted to different hole walls without the need for manual locking, reducing the complexity of operation.
