Description

Technical Field

[0001] The present invention relates to the technical field of blasting engineering auxiliary equipment, and in particular to a safe and environmentally friendly auxiliary underwater blasting device and a use method thereof. Background Art

[0002] Underwater blasting refers to blasting operations carried out in water, on the bottom of water or in temporary media. Common methods of underwater blasting include exposed blasting, drilling blasting and chamber blasting. The principle of underwater blasting is to utilize the detonation phenomenon produced by the explosion of emulsion explosives. The structure is destroyed mainly by the violent destructive effect produced by the shock wave energy and high-energy density gas.

[0003] The current purpose of underwater blasting is generally for engineering construction, such as leveling reef areas and clearing obstacles before collecting seabed resources. Because blasting is carried out underwater, especially in offshore areas, and is likely to involve many rare offshore marine habitats, if the animals in the ocean are not temporarily driven away in advance, it is easy to cause marine life such as dolphins and seals that rely on sound signals to obtain and communicate information to be affected and disturbed. The changes in the underwater sound field caused by blasting construction noise will have a significant impact on marine mammals, and high-energy underwater blasting noise has a great risk of causing injury and death to animals.

[0004] The traditional driving operation is to use the noise driving method, which refers to the use of the ship's air compressor to create irregular noise or use other sound-driven equipment to create noise to drive marine life away from the construction sea area. However, the traditional noise driving method relies on driving the ship to the seabed, and the effect is poor in deep water and areas with turbulent water. Secondly, the driving ship generally does not stay in one place, but cruises back and forth, and cannot maintain continuous driving in local areas. This method leads to a greater impact on marine life in the early stage. In the later stage, marine life may gradually become familiar with and adapt to the noise and no longer avoid it directly. Some animals will return to the construction sea area as a matter of course, making it difficult to drive away the marine life in the blasting area, resulting in a large number of marine life still existing in the blasting area during the blasting construction. Summary of the invention

[0005] In view of the problems in the related art, the present invention proposes a safe and environmentally friendly underwater blasting device, through which most of the marine life in the construction sea area can be effectively and continuously driven away, reducing the damage of underwater blasting to the marine life.

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is: a safe and environmentally friendly auxiliary underwater blasting device, including a device body, wherein the device body is provided with a surface component and an underwater component,

The device body is provided with a lifter, which moves relative to the water surface component along the coil. The device body is also provided with an airbag mechanism, which is used to keep the buoyancy suspension and lifting of the device body relative to the water surface.

[0012] As a further configuration of the above scheme, the bottom frame of the underwater component is also connected to a positioning claw frame, which includes a connecting chain and an embedded anchor, and the embedded anchor is provided with an expansion device with a driving unit and the expansion device includes a relatively swinging anchor rod.

[0013] As a further configuration of the above solution, the coiled cable includes a cable body and a cable, the cable body is provided with a wire groove, and the lifter includes a wire ring, and the wire ring is used to guide the cable to be inserted into the wire groove.

[0014] As a further configuration of the above scheme, the wire ring includes a wire retaining ring and a wire removal guide block. The wire retaining ring is sleeved on the outer ring of the cable body to guide the cable into the wire groove. The wire removal guide block is arranged at an angle relative to the wire groove to push the cable out of the wire groove when the device body floats.

[0015] As a further configuration of the above scheme, the lifter includes a lifting motor powered and started by a water flow power generation mechanism and a climbing rope device, wherein the climbing rope device includes a group of fixed clamping claws fixed to the device body and a group of sliding blocks with dynamic clamping claws that can move relative to the fixed clamping claws.

[0016] As a further configuration of the above scheme, the fish-repelling device includes a power converter and an ultrasonic emitting device with adjustable sound wave frequency band, and the ultrasonic emitting device is also connected to a remotely controlled sound wave frequency band adjustment component.

[0017] As a further configuration of the above scheme, the airbag mechanism is also provided with a water and gas filling and discharging mechanism, including an air suction pump and a drainage pump arranged in the bag body of the airbag mechanism. The air inlet pipe of the air suction pump is embedded in the coil and air is supplied through the floating block connected to the water surface component. When the air suction pump is started, the drainage pump is linked to pump water from the bag body to the outside. The bag body is also provided with an electromagnetically controlled one-way water inlet valve, and the one-way water inlet valve is normally closed.

[0018] A method for using a safe and environmentally friendly auxiliary underwater blasting device, comprising the following steps

[0019] S1: According to the construction area, pre-detect and calculate the approximate depth, select a device with a suitable length of cable, and lower the device body, surface components and underwater components at the predetermined position. The order of placement is to first lower the anchor, the connecting chain and the bottom frame;

[0020] S2: When lowering the underwater component, the winch wheel of the surface component is controlled so that the cable is pulled out as the underwater component sinks, and after the cable is no longer automatically reeled out, the device body and the surface component are simultaneously lowered into the water;

[0021] S3: After the device body and the surface component are launched into the water, the cable wheel is started by controlling the driving motor to slowly reel in the cable, so that the surface component is moved to the top of the bottom frame of the underwater component by pulling the cable, and then the cable wheel is locked to limit the use length of the cable;

[0022] S4: Then the device body is controlled to start a sinking mode, which includes loosening the fixed clamping claw and the dynamic clamping claw of the lifter, and opening the water inlet channel by electromagnetically controlling the one-way water inlet valve to fill the bladder with water, thereby causing the device body to sink along the coiled cable;

[0023] S5: Both the device body and the surface component are equipped with a power storage system, and are powered by a solar power storage device and a water flow power generation mechanism. After the device body sinks, the water flow power generation mechanism takes effect and continuously generates electricity to power the device through the impact of water flow. At the same time, the fish-repelling device is started according to preset parameters and is adjusted and controlled by a remotely controlled sound wave frequency band adjustment component;

[0024] S6: When the device body floats up, both the air suction pump and the drainage pump will be started. The air suction pump will draw air from the water surface through the air intake pipe in the coil and discharge the seawater in the bladder through the drainage pump;

[0025] S7: When suspended or stepping up and down, a part of the air and seawater in the sac keeps the buoyancy and gravity basically balanced. At this time, the fixed clamping claw and the dynamic cable clamping claw work together. When in action, the fixed clamping claw clamps the cable coil, and the dynamic cable clamping claw releases when the slider slides. When the slider moves to the farthest end of the fixed clamping claw, the dynamic cable clamping claw clamps the cable coil. When the fixed clamping claw is released, the driving structure of the slider flips, causing the slider to move toward the fixed clamping claw, and the device body rises, and vice versa.

[0026] Furthermore, as mentioned above, a speed sensor is also provided on the embedded anchor. After the embedded anchor sinks to the bottom, the driving unit provided thereon is started, driving the anchor rod of the expansion device to swing relatively to form a positioning on the bottom of the water.

[0027] Beneficial effects: The significant effects of the present invention include: the present invention adopts an independently positioned auxiliary device to position and release the fish-driving equipment, and accurately positions and places it when it is released, so that it can stably and continuously drive fish within a certain range through the device, and the device of the present invention can achieve continuous lifting and lowering of the water level to drive fish, which is relative to the existing surface floating fish driving technology, and avoids the problem of poor driving effect and incomplete driving in some deep waters. In addition, the equipment using this device can continuously and stably output the power supply based on multiple energy supplies to reduce and avoid repetitive problems, and the problem of returning after getting used to it under continuous and intermittent driving is solved.

The wire retaining ring 72 is sleeved on the outer ring of the cable body 44 to guide the cable 43 to be pressed into the wire groove 45. The wire removal guide block 73 is arranged at an angle relative to the wire groove 45 to push the cable 43 out relative to the wire groove 45 when the device body 1 floats.

The bladder body 61 is also provided with an electromagnetically controlled one-way water inlet valve 65, and the one-way water inlet valve 65 is normally closed.

[0047] like Figure 1 The safe and environmentally friendly auxiliary underwater blasting device comprises a device body 1, a surface component 2 and an underwater component 3;

[0048] Among them, a cable 4 is provided between the surface assembly 2 and the bottom assembly 3 of the present invention for connection. Figure 1 One end of the coil 4 is connected to the underwater assembly 3 and the other end is connected to the surface assembly 2. A cable wheel 41 is provided on the surface assembly 2. In addition, the device body 1 of this embodiment is as shown in FIG. Figure 1Located on the cable 4 relative to the surface assembly 2 and the underwater assembly 3 activities, the activity of the cable 4 is limited by the cable;

[0049] The water surface assembly 2 includes a floating body 21 for floating on the water surface, a solar energy storage device 22 for converting electric energy, a winch wheel 41 for winding and releasing the coil cable 4, and a driving motor 23;

[0050] The underwater assembly 3 includes a bottom frame 31 connected to the cable 4, and the bottom frame 31 includes a positioning claw frame 32. The positioning claw frame 32 is divided into a connecting chain 33 and an embedded anchor 34. The embedded anchor 34 imitates the structural design of a ship anchor, and includes an expansion device 35 with a driving unit and the expansion device 35 includes a relatively swinging anchor rod 36. It is worth noting that the expansion device 35 provided in the embedded anchor 34 of this embodiment is provided with a driving unit. The significance of the driving unit is to control the swing of the driving anchor rod 36 when receiving a command, such as Figure 1 The anchor rod 36 shown includes a main rod connected to the connecting chain 33 and an insert rod that is hinged and swung through an expansion device 35. When in use, the drive unit can drive the main rod to hinge and swing relative to each other, thereby improving the gripping force. Conversely, when retracting, the angle between the main rod and the insert rod can be reduced through hinged swing, thereby reducing water resistance and facilitating extraction from the bottom mud.

[0051] The device body 1 is provided with a fish-driving device 10 and a water flow power generation mechanism 20. When the device body 1 is under the water surface, the water flow power generation mechanism 20 drives the internal power generation mechanism to rotate and generate electricity through the power of the water flow, and cooperates with the solar power storage device 22 to store energy when not in use, so as to supply energy to the fish-driving device 10 and to ensure its continuous use. The device body 1 of this embodiment is provided with a lifter 7, such as Figure 1 , Figure 3The lifter 7 shown in the figure moves along the cable coil 4 relative to the water surface assembly 2. The cable coil 4 includes a cable body 44 and a cable 43. The cable body 44 is provided with a cable groove 45. The lifter 7 includes a wire ring 71. The wire ring 71 is used to guide the cable 43 to be inserted into the cable groove 45. The wire ring 71 includes a buckle ring 72 and a wire removal guide block 73. The buckle ring 72 is sleeved on the outer ring of the cable body 44 to guide the cable 43 to be pressed into the cable groove 45. The wire removal guide block 73 is arranged at an inclined surface relative to the cable groove 45, and is used to push the cable 43 relative to the cable groove 45 when the device body 1 floats. The design principle of the wire ring 71 is similar to that of the pull A wire groove 45 is provided between the chain head, the cable body 44 and the cable 43, and the cable body 44 has a certain elastic force, so that the cable 43 can be embedded in the cable body 44. The purpose of the modified structural design is that when in use, the device body 1 is lifted relative to the cable body 44, and the climbing device 77 of the lifter 7 is used to climb or descend. In this process, the device body 1 will reel in or release the cable 43. When climbing upward, the cable 43 is acted upon by the wire removal guide block 73, and is continuously removed from the wire groove 45 and reeled into the device body 1. On the contrary, the cable 43 is continuously rolled out and pressed into the wire groove 45 by the wire buckle ring 72 of the wire ring 71.

[0052] The device body 1 is also provided with an air bag mechanism 6, and the air bag mechanism 6 is used to keep the device body 1 buoyantly suspended and lifted relative to the water surface.

[0053] Furthermore, the solar power storage device 22 is used to generate electricity and supply power to the drive motor 23, and the drive motor 23 is used to drive the cable wheel 41 to store and wind the coil cable 4.

[0054] Furthermore, the lifter 7 includes a lifting motor powered and started by a water flow power generation mechanism 20 and a climbing rope device 77, wherein the climbing rope device 77 includes a set of fixed clamping claws 79 fixed to the device body 1 and a set of sliders 70 with dynamic clamping claws 78 that can move relative to the fixed clamping claws 79.

[0055] Furthermore, the fish-repelling device 10 includes a power converter and an ultrasonic emitting device 19 with adjustable sound wave frequency band, and the ultrasonic emitting device 19 is also connected to a remotely controlled sound wave frequency band adjustment component.

[0056] Furthermore, the airbag mechanism 6 is also provided with a water and gas filling and discharging mechanism, including an air suction pump 62 and a water discharge pump 63 arranged in the bladder body 61 of the airbag mechanism 6. The air inlet pipe 64 of the air suction pump 62 is embedded in the coil 4, and air is supplied through the floating block 24 connected to the water surface component 2. When the air suction pump 62 is started, the water discharge pump 63 is linked to pump water from the bladder body 61 to the outside. The bladder body 61 is also provided with an electromagnetically controlled one-way water inlet valve 65, and the one-way water inlet valve 65 is normally closed.

[0057] A method for using a safe and environmentally friendly auxiliary underwater blasting device as described above includes the following steps:

[0058] S1: According to the construction area, the approximate underwater depth is pre-detected and calculated (the underwater situation can also be determined by sonar), and then the device of the present invention with a suitable length of the coil 4 is selected. Subsequently, the device body 1, the surface component 2 and the underwater component 3 are lowered at the predetermined position. The order of placement is as follows: the embedded anchor 34, the connecting chain 33 and the bottom frame 31 are lowered first. It is worth noting that when the positioning claw frame 32 is launched into the water, the expansion device 35 of the embedded anchor 34 is retracted, and then opened after the descent is completed. According to the actual situation, the embedded anchor 34 should be launched in advance relative to the pre-calculated positioning point, which is about the length of a connecting chain 33, and then moved toward the expected positioning point, and then the remaining devices are launched into the water. The purpose is that after the embedded anchor 34 of the positioning claw frame 32 is embedded in the water bottom, there is still a section of connecting chain 33 between the bottom frame 31 and the embedded anchor 34. Within the circular range with the connecting chain 33 as the radius and the embedded anchor 34 as the center, the bottom frame 31 and other devices may move to a certain extent. In order to be in the predetermined position as much as possible, the embedded anchor 34 needs to be stably embedded in the water bottom.

[0059] S2: When lowering the underwater component 3, the winch wheel 41 of the surface component 2 is controlled to pull out the coil 4 as the underwater component 3 sinks, and after the coil 4 is no longer automatically rolled out, the device body 1 and the surface component 2 are simultaneously lowered into the water. When the underwater component 3 is lowered into the water, the winch wheel 41 is in a loosened state, allowing the coil 4 to be freely rolled out as the underwater component 3 sinks into the water, until the bottom frame 31 of the underwater component 3 reaches the bottom of the water;

[0060] S3: After the device body 1 and the water surface component 2 are launched into the water, the cable wheel 41 is started by controlling the driving motor 23 to slowly reel in the cable 4, so that the water surface component 2 is pulled and moved to just above the bottom frame 31 of the underwater component 3 by the pulling of the cable 4, and then the cable wheel 41 is locked to limit the use length of the cable 4. As mentioned above, after the underwater component 3 gets the bottom frame 31 and reaches the bottom of the water, the driving motor 23 is started to reel in the cable 4. Based on the fixation of the positioning claw frame 32, the reeling of the cable wheel 41 will first move the unfixed water surface component 2, and after moving to just above the bottom frame 31, the continued reeling will pull the bottom frame 31. The purpose of the present invention is that when the water surface component 2 moves to the top of the bottom frame 31, the winch wheel 41 will stop working. The stop command can be passively judged that it is at the required position by increasing the output torque of the drive motor 23 driving the winch wheel 41 when the water surface component 2 reaches the top of the bottom frame 31. At this time, the cable 4 is in a basically vertical state, and based on the cooperation of the bottom frame 31 and the water surface component 2, the cable 4 becomes the guide cable for the vertical lifting of the device body 1, which can avoid the positioning problem of the device body 1 being impacted by the water flow underwater, and can also be used to more conveniently realize the vertical lifting action of the device body 1 by the cable 4;

[0061] S4: Then the device body 1 is controlled to start the sinking mode, which includes loosening the fixed clamping claw 79 and the dynamic clamping claw 78 of the lifter 7, and opening the water inlet channel by electromagnetically controlling the one-way water inlet valve 65, so that the bag 61 is filled with water, so that the device body 1 sinks along the coil 4;

[0062] S5: The device body 1 and the water surface component 2 are both equipped with a power storage system, and are powered by a solar power storage device 22 and a water flow power generation mechanism 20. After the device body 1 sinks, the water flow power generation mechanism 20 takes effect and continuously generates electricity to power the device through the impact of water flow. At the same time, the fish driving device 10 is started according to the preset parameters, and is adjusted and controlled by the remotely controlled sound wave frequency band adjustment component. It is worth noting that the lifting and lowering of the device body 1 of this embodiment is also provided with an auxiliary mechanism to cooperate and realize, including the air bag mechanism 6 provided on the device body 1, which changes the proportion of air inside the device body 1 to form a floating ball by sucking air and draining water from the water surface, and the buoyancy is used to make the device body 1 float up, and the balance force of underwater suspension is achieved by the cooperation of the fixed clamping claw 79, the dynamic clamping claw 78 and the slider 70 of the climbing rope device 77, so as to realize the suspension or stepping lifting and lowering of the device body 1 by relying on the coil 4;

[0063] S6: When the device body 1 floats up, both the air suction pump 62 and the drainage pump 63 are started, and the air suction pump 62 draws air from the water surface through the air inlet pipe 64 in the coil 4, and discharges the seawater in the bladder 61 through the drainage pump 63;

[0064] S7: When suspended or stepping up and down, a part of the air and seawater in the bag 61 keeps the buoyancy and gravity basically balanced. At this time, the fixed clamping claw 79 and the dynamic clamping claw 78 work together. When in action, the fixed clamping claw 79 clamps the coil rope 4, and the dynamic clamping claw 78 is released when the slider 70 slides. When the slider 70 moves to the farthest end of the fixed clamping claw 79, the dynamic clamping claw 78 clamps the coil rope 4. The fixed clamping claw 79 is released and the driving structure of the slider 70 is flipped, so that the slider 70 moves toward the fixed clamping claw 79, and the device body 1 rises, and vice versa.

[0065] It is worth noting that the device of the present embodiment is designed to reduce wireless transmission as much as possible, and instead reduces the interference problem of underwater wireless transmission by embedding the cable 43 in the coil 4. The coil 4 can not only increase the working area of ​​the positioning and limiting device and simplify the complexity of the equipment, but also better transmit signals and energy, reducing the difficulty of production.

[0066] Furthermore, the embedded anchor 34 of S1 is also provided with a speed sensor. After the embedded anchor 34 sinks to the bottom, the driving unit arranged thereon is started, driving the anchor rod 36 of the expansion device 35 to swing relatively to form the positioning of the bottom of the water. The significance of setting this structure is that a speed sensor is arranged on the embedded anchor 34. During the sinking process of the positioning claw frame 32 after launching into the water, the speed sensor continuously feeds back a signal. After sinking to the bottom, the signal will change, which can be used as a trigger signal of the start instruction of the triggering driving unit, and another trigger signal of the driving unit can be remotely controlled to start.

[0067] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
