Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of breaking seabed reefs, in particular to a composite intelligent seabed reef breaking system and method. BACKGROUND

[0002] In recent years, with the rapid development of marine vessels, the port channel is continuously widened, deepened and radiated outward, making important contributions to shipping construction and economic development. However, the existence of navigation-obstructing reefs has caused a lot of hidden dangers for safe navigation of ships, greatly hindering the improvement of marine shipping capacity. In order to regulate the problem of channel reef obstruction, according to the actual engineering experience, mechanical reef breaking, chemical blasting and other rock breaking methods have been proposed, among which underwater drilling and blasting method is used as the main construction method of underwater reef blasting because of its high construction efficiency and small explosive consumption. However, the underwater shock wave and noise generated during blasting cause serious harm to the surrounding marine organisms, not only destroying the marine ecological environment. How to take reasonable scheme in the process of rock breaking, while taking into account the marine ecological environment and efficient engineering economy, has become a problem worth noting. As a commonly used scheme of mechanical rock breaking, heavy hammer rock drilling can not only meet the environmental protection requirements, but also directly solve the safety hidden danger of navigation-obstructing reefs. However, due to the influence of long-term geological action and tidal climate change, the mechanical strength of reefs in different marine areas is significantly different. If the mechanical strength of the broken navigation-obstructing reefs is relatively low, the existing engineering technology can complete the given target efficiently and at low cost; otherwise, it will not only reduce the rock breaking efficiency, but also greatly increase the equipment loss. Therefore, it is very important to explore a combined rock breaking scheme with small influence on the surrounding ecological environment, stable rock breaking efficiency and relatively low equipment loss, as well as related auxiliary construction methods to solve the problems existing in the construction process.

[0003] The existing devices include chemical blasting technology, heavy hammer rock drilling technology, water jet (high pressure water gun) technology, and carbon dioxide complete fracturing technology. However, the above-mentioned technologies have the following problems: chemical blasting has too much pollution to the environment and destroys the ecological balance; single use of heavy hammer rock drilling technology has no obvious breaking effect on seabed super-hard reefs, and the hammer is easy to be damaged; water jet (high pressure water gun) technology can only drill small holes in a single area and cannot be used in large-scale super-hard rock breaking; carbon dioxide fracturing technology has a certain limit on the gas pressure, and the complete breaking of rock blocks is limited, so the rock breaking efficiency is not high; at the same time, most of the existing technologies are mechanically controlled and cannot realize intelligent control.

[0041] Further, the pulley 520 in the installation ring mechanism transmits the steel cable transmitted by the hoisting mechanism, so that the aforementioned rock drilling weight device, carbon dioxide fracturing device and water jet device can be hoisted, at the same time, the pulley can move along the circumference of the ring body with the guide rod axial as the center, so that the action of the pulley can be controlled under the control of the central control device, so that the rock drilling weight device, carbon dioxide fracturing device and water jet device can be transferred to the appropriate work station at the appropriate time, so as to avoid interference between the three devices during work, so as to improve the efficiency of seabed reef crushing.

[0042] As a preferred technical solution of the embodiment, the rock drilling weight device 410, the carbon dioxide pre-splitting device 420 and the water jet device 430 are arranged vertically from top to bottom along the guide rod 30, so that under the action of the hoisting mechanism, the rock drilling weight device 410, the carbon dioxide pre-splitting device 420 and the water jet device 430 can be driven to move to the rock breaking position respectively, so as to obtain better seabed reef crushing effect.

[0043] Referring to Figure 12 Further, the carbon dioxide pre-cracking device 420 comprises a carbon dioxide storage tank 421, a first pressurizing device 422, and a pre-cracking pipe 423, the pre-cracking pipe comprising a pipe body 4231 and a cracking point 4232 arranged on the pipe body, the cracking point being electrically connected with the central control device 60. In use, the carbon dioxide storage tank delivers carbon dioxide to the first pressurizing device, forms supercritical carbon dioxide (i.e. a state of very high pressure) in the first pressurizing device, and delivers the supercritical carbon dioxide to the pre-cracking pipe. The pre-cracking pipe is composed of a pipe and a cracking point, and whether the cracking point is opened or not is controlled by the central control device. In operation, the hoisting mechanism is started to deliver the carbon dioxide pre-cracking device to the hole drilled by the water jet device, the cracking point is opened, a large amount of high-pressure carbon dioxide gas is sprayed out, and micro-cracks are formed on the rock.

[0044] Referring to Figure 11 Further, the water jet device 430 comprises a second pressurizing device 431 and a high-pressure water gun 432 arranged at the output end of the second pressurizing device. The water jet device further comprises a positioning mechanism, which is electrically connected with the central control device 60. Specifically, the positioning mechanism can be a GPS positioning device. In operation, water is directly obtained from seawater, is pressurized by the second pressurizing device to be converted into high-pressure water, is then delivered to the high-pressure water gun, and is connected with the positioning mechanism on the high-pressure water gun to obtain real-time GPS positioning information and transmit the information to the central control device, so that the central control device can control the size and direction of the hole drilled.

[0045] Further, the rock drilling weight device 410 comprises a rock drilling weight 411, which is connected with a pulley through a steel cable, and the pulley is connected with the hoisting mechanism, which is controlled by the central control device. When the rock drilling weight system is started to operate, the hoisting mechanism drives the rock drilling weight to make free fall. After the operation is completed, the hoisting mechanism is started to recover the rock drilling weight to the original height.

[0046] Referring to Figure 3 , Figure 4As the preferred technical scheme of the embodiment, the ring body 510 is internally provided with a cavity, the cavity is internally slidably provided with a sliding ring 511, the top of the ring body is provided with sliding grooves 512 which are locally distributed along the circumference of the ring body, the sliding grooves are slidably connected with sliding blocks 513, and the sliding blocks are fixedly connected with the sliding ring 511. The pulley 520 is rotatably arranged on the sliding block 513 through a support 540. It should be noted that the sliding grooves in the embodiment are locally distributed along the circumference of the top of the ring body, that is, the sliding grooves are not a complete ring. When the sliding ring slides in the cavity of the ring body, the sliding blocks can slide in the sliding grooves, that is, the sliding blocks and the pulley thereon can locally rotate along the ring body, so as to move the rock drilling weight device 410, the carbon dioxide pre-splitting device 420 and the water jet device 430 to a suitable position.

[0047] It should be noted that, in the embodiment, in order to improve the convenience of adjusting the rock drilling weight device 410, the carbon dioxide pre-splitting device 420 and the water jet device 430, when the ring body is installed, the part of the ring body which is not provided with the sliding grooves can be arranged on the side close to the ship body. In this way, the part of the ring body which is provided with the sliding grooves is located on the outer side of the ship body, so that the azimuth adjustment of the rock drilling weight device 410, the carbon dioxide pre-splitting device 420 and the water jet device 430 can be facilitated.

[0048] With reference to Figure 5 Further, in order to realize the stable sliding of the sliding ring in the cavity of the ring body, a guide convex strip 514 is arranged at the bottom of the cavity. Correspondingly, the bottom of the sliding ring 511 is provided with a guide groove which matches the guide convex strip. In order to drive the rotation of the sliding ring, a power mechanism for driving the sliding ring 511 to move is further arranged on the outer wall of the guide rod 30. Specifically, the power mechanism comprises a motor 551 fixedly arranged on the outer wall of the guide rod, a driving gear 552 arranged on the output end of the motor, and a driven gear 553 arranged on the inner side of the sliding ring and engaged with the driving gear. In use, the driving gear is driven to rotate under the driving of the motor, and the driving gear in turn drives the driven gear engaged therewith to rotate. Since the driven gear is fixedly connected with the inner side of the sliding ring, the sliding ring is simultaneously driven to rotate in the cavity of the ring body when the driven gear rotates, thereby realizing the stable action of the sliding ring.

[0049] With reference to Figure 6 , Figure 7As a preferred technical solution of this embodiment, the outer wall of the ring body 510 is slidably connected to a mounting block 515 fixedly connected to the sliding block 513, and two guide wheels 516 for transmitting the steel cable 530 are symmetrically arranged on the mounting block 515; the outer wall of the ring body 510 is also fixed with a guide ring 517 distributed along its circumference and corresponding to the position of the sliding groove 512, and the guide ring passes through the mounting block. When in use, the guide ring is fixed to the outer wall of the ring body, and the steel cable at the output end of the lifting mechanism passes through the two guide wheels and is transmitted to the pulley, and extends outward through the pulley to be connected to the rock drilling hammer device 410, the carbon dioxide pre-cracking device 420 or the water jet device 430. When the mounting block slides with the sliding block, it will slide along the guide ring circumferentially of the ring body, and can synchronously drive the steel cable to be deployed or retracted along the outer wall of the ring body to achieve the release or retraction of the steel cable.

[0050] Furthermore, in order to achieve stable sliding of the mounting block along the outer wall of the ring body, an annular groove is opened on the outer wall of the ring body, and a slider is slidably connected in the groove. The end of the slider away from the groove is fixedly connected to the mounting block. In this way, when the sliding block slides in the sliding groove, it can synchronously drive the mounting block to slide along the groove.

[0051] Reference Figure 8 、 Figure 9 Furthermore, a plurality of support rods 518 are slidably connected to the outer wall of the guide ring 517, and a support ring 519 is fixedly provided at one end of the support rod away from the guide ring. It should be noted that the sides of two adjacent support rods are provided with matching magnetic blocks, that is, the two adjacent support rods 518 can be magnetically attracted to or separated from each other, and a magnetic cylinder 521 is fixedly provided on the outer wall of the mounting block 515. In this way, the support rod 518 close to the mounting block 515 can be magnetically attracted to or separated from the mounting block when it is magnetically attracted to or separated from the magnetic cylinder.

[0052] Further, the bottom of each support rod 518 is provided with a limiting post 522, and the outer wall of the ring body 510 is provided with a plurality of limiting seats 523 at intervals along the extension range of the sliding groove 512. The limiting seat 523 is matched with the limiting post 522. Specifically, the lengths of the plurality of limiting posts 522 decrease along a certain direction of the circumference of the ring body 510, and the heights of the limiting seats 523 increase along the certain direction of the circumference of the ring body 510. The matching surfaces of the limiting post 522 and the limiting seat 523 are provided with matching magnetic surfaces 524. In this embodiment, the number of limiting posts and limiting seats is three, and the limiting seats are uniformly arranged on the outer wall of the ring body along the circumference of the sliding groove. In use, the steel cable is conveyed from the output end of the hoisting mechanism to the ring body, and the steel cable is placed in the support ring. The plurality of support rods are adsorbed together by the magnetic adsorption block, and the support rods adsorbed together are located on the side wall of the mounting block. When it is necessary to move the pulley to the side of the ring body away from the ship body in order to facilitate the hoisting operation, the motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate, the driven gear drives the sliding ring to slide in the cavity of the ring body, so as to drive the sliding block to slide, and the sliding block drives the pulley to slide. Since the sliding block drives the mounting block to slide along the guide ring at the same time, the mounting block drives the plurality of support rods and the support ring to slide when sliding. Thus, the movement process of the sliding block, the pulley and the steel cable along the inside of the sliding groove-the outside of the sliding groove-the inside of the sliding groove can be realized. During the movement process, the support rod will be moved to the position of the corresponding limiting seat when moving with the mounting block, so that the corresponding limiting post and the limiting seat are magnetically adsorbed, so that the limiting post is released together with the support rod and the support ring at the position of the limiting seat, so as to use the released support ring to comb and support the steel cable, avoid the released steel cable from being messy, and facilitate the recovery of the steel cable. When it is necessary to recover the steel cable to the hoisting mechanism, the mounting block is slid with the sliding block, the magnetic adsorption cylinder thereon adsorbs the limiting post released to the limiting seat, and the plurality of limiting posts and the support rods are adsorbed together. At the same time, the hoisting mechanism recovers the steel cable along the support ring.

[0053] The limiting posts on the support rods and the limiting seats on the outer wall of the ring body in this embodiment are different. Each limiting post is matched with its corresponding limiting seat, that is, a certain limiting post can only be magnetically adsorbed with the limiting seat at its corresponding position, so as to realize the release or recovery of the support ring.

[0054] It should be noted that the certain direction in this embodiment can be the clockwise direction along the ring body, or the counterclockwise direction along the ring body, which is not limited here.

[0055] During operation, the central control unit activates, and the high-pressure water gun adjusts to the appropriate position via the pulley. The second pressurizing unit activates and applies pressure, ejecting a high-pressure water stream, breaking the rock and forming a small hole. After the water jet is completed, the pulley retracts the high-pressure water gun, and the central control unit controls the pulley and the high-pressure water gun to rotate inward along the guide rod. The central control unit then activates, and the lifting mechanism drives the pulley to extend the pre-splitting pipe into the small hole drilled. The CO2 storage tank feeds the stored CO2 into the first pressurizing unit, forming supercritical CO2, which is then fed into the pre-splitting pipe. The central control unit controls the detonation, causing a large amount of high-pressure gas to be ejected, forming microcracks. After the CO2 fracturing operation is completed, the lifting mechanism drives the pulley to return the pre-splitting pipe to its original position. The central control unit controls the pulley and the pre-splitting pipe to rotate inward along the guide rod. The lifting mechanism is then activated, driving the rock drill hammer into a free fall motion, penetrating the rock filled with microcracks. After the operation is completed, the lifting mechanism drives the rock drill hammer back to its original position. This cycle repeats, achieving the desired rock breaking effect.

[0056] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

9. A method for crushing seabed reefs using the composite intelligent seabed reef environmentally friendly crushing system according to claim 8, characterized in that: The following steps are involved: S10: The central control device is activated, the high-pressure water gun is adjusted to its position via the pulley, and the second pressurizing device is activated to increase pressure, ejecting a high-pressure water flow to break the rock and form a small hole. After the water jetting is completed, the pulley retracts the high-pressure water gun, and the central control device controls the pulley and the high-pressure water gun to rotate along the guide rod and rotate inward; S20: The lifting mechanism drives the pulley to extend the pre-cracking pipe into the drilled hole. The CO2 storage tank inputs the stored CO2 into the first pressurizing device. After forming supercritical CO2, it is input into the pre-cracking pipe. The central control device controls the detonation, and a large amount of high-pressure gas is ejected, forming microcracks. S30: After the carbon dioxide fracturing operation is completed, the lifting mechanism drives the pulley to restore the pre-cracking pipe to its original position, and the central control device controls the pulley and the pre-cracking pipe to rotate along the guide rod to the inside; S40: Subsequently, the lifting mechanism is started to drive the rock drilling hammer to perform free fall motion to penetrate the rock full of micro-cracks; after the rock drilling hammer operation is completed, the lifting mechanism drives the rock drilling hammer to return to its original position; S50: This cycle is repeated to break up the seabed reefs.
