Description

Technical Field

[0001] The present invention relates to the technical field of seabed reef crushing, and in particular to a composite intelligent seabed reef environmentally friendly crushing system and method. Background Art

[0002] In recent years, with the rapid development of shipping, port channels have been continuously widened, deepened and radiated outward, making important contributions to shipping construction and economic development. However, the existence of obstructing reefs has caused a lot of hidden dangers for the safe navigation of ships, greatly hindering the improvement of marine shipping capacity. In order to rectify the problem of reef obstruction in the channel, rock breaking methods such as mechanical reef breaking and chemical blasting have been proposed based on actual engineering experience. Among them, underwater drilling and blasting is used as the main construction method for underwater reef blasting due to its high construction efficiency and low consumption of explosives. However, the underwater shock waves and noise generated by blasting during the construction process cause serious damage to the surrounding marine life, which not only destroys the marine ecological environment. How to adopt reasonable solutions in the rock breaking process while taking into account the marine ecological environment and the economic and efficient advancement of the project has become a problem worthy of attention. Heavy hammer rock drilling is a common solution for mechanical rock breaking. It can directly solve the safety hazards of obstructing reefs while meeting environmental protection requirements. However, due to the influence of long-term geological effects and tidal climate change, there are significant differences in the mechanical strength of reefs in different marine areas. If the mechanical strength of the broken obstructing reef is relatively low, the existing engineering technology can achieve the set goal with low cost and high efficiency; otherwise, it will not only reduce the rock breaking efficiency but also greatly increase the loss of machinery and equipment. Therefore, it is very important to explore a combined rock breaking solution with little impact 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] Existing devices include: chemical blasting technology, heavy hammer rock drilling technology, water jet (high-pressure water gun) technology, carbon dioxide complete fracturing technology, etc. However, the above technologies have the following problems: chemical blasting does not pollute the environment too much and destroys the ecological balance; the heavy hammer rock drilling technology alone has an insignificant crushing effect on the super-hard reefs on the seabed, and the hammer is easily damaged; water jet (high-pressure water gun) technology can only drill a relatively small hole in a single area and cannot be used on a large scale in the breaking of super-hard rocks; if the carbon dioxide fracturing technology is used alone, due to the certain limit of gas pressure, the complete crushing of rock blocks is limited and the rock breaking efficiency is not high; at the same time, most of the existing technologies are mechanically controlled and cannot achieve intelligent control. Summary of the invention

[0004] The present invention provides a composite intelligent environmentally friendly seabed reef crushing system and method. First, water jet technology is used to drill holes in the rock, giving full play to the ability of high-pressure water guns to drill small holes. Then a carbon dioxide fracturing device is placed to pre-crack the rock using supercritical carbon dioxide. Finally, a heavy hammer is used to drill the rock to quickly break the rock. The present invention combines the advantages of three technologies: water jet technology, carbon dioxide fracturing technology, and heavy hammer rock drilling technology. Compared with single rock breaking, it has great advantages. The three technologies are combined to maximize the rock breaking efficiency. At the same time, all operations are controlled by computers, and fully automatic intelligent control can be achieved.

DETAILED DESCRIPTION

[0039] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0040] To achieve the above purpose, the embodiment of the present invention adopts the following technical solution: Figure 1 , Figure 2 , Fig.10A composite intelligent submarine reef environmental protection crushing system includes a hull 10, a mechanical arm 20, a guide rod 30, a lifting mechanism 40, a mounting ring mechanism 50 and a central control device 60, wherein the mechanical arm is arranged on the outside of the hull, the guide rod 30 is vertically distributed in the free end of the mechanical arm, the lifting mechanism is arranged in the hull, and the number of the lifting mechanisms in this embodiment is three, and the output ends of the three lifting mechanisms are respectively provided with a rock drilling hammer device 410, a carbon dioxide pre-cracking device 420 and a water jet device 430, the mounting ring mechanism is arranged on the guide rod 30, and the number of the mounting ring mechanisms corresponds to the number of the lifting mechanisms, that is, the number of the mounting ring mechanisms in this embodiment is also three, and further, the mounting ring mechanism includes a ring body 510 coaxially fixed on the outside of the guide rod 30, a pulley 520 capable of rotating at a set angle along the circumference of the ring body with the axial direction of the guide rod as the center, and a pulley 520 arranged at the output of the lifting mechanism The steel cable 530 is transmitted outward through the pulley at the outlet end, and the central control device is arranged in the hull, and is used to control the water jet device 430, the carbon dioxide pre-cracking device 420 and the rock drilling hammer device 410 to perform reef crushing operations in sequence. When in use, the water jet device is first used to drill a hole in the rock to give full play to the ability of the high-pressure water gun to drill small holes, and then the carbon dioxide fracturing device is placed to use supercritical carbon dioxide to pre-crack the rock, and finally the rock is drilled with a heavy hammer to quickly crush the rock. The present invention combines the advantages of the three technologies of water jet technology, carbon dioxide fracturing technology, and heavy hammer rock drilling technology. Compared with the single rock breaking technology, it has a greater advantage and can maximize the rock breaking efficiency; at the same time, the crushing system uses natural raw materials such as carbon dioxide and water, does not use chemical fuels, is more environmentally friendly to the environment, and has the characteristics of no pollution to the environment; in addition, the present invention can realize the automatic control of rock breaking, can realize all-round automatic operation, and reduce labor costs.

[0041] Furthermore, the pulley 520 in the mounting ring mechanism transmits the steel cable transmitted by the lifting mechanism, so that the aforementioned rock drilling hammer device, carbon dioxide fracturing device and water jet device can be lifted. At the same time, the pulley can move circumferentially along the ring body with the axial direction of the guide rod as the center. Therefore, under the control of the central control device, the pulley movement can be controlled to transport the rock drilling hammer device, carbon dioxide fracturing device and water jet device to the appropriate work station at the appropriate time, thereby avoiding interference between the above three devices during the working process, so as to improve the efficiency of seabed reef crushing.

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

[0043] Reference Fig.12 Further, the carbon dioxide pre-cracking device 420 includes a carbon dioxide storage tank 421, a first pressurizing device 422 and a pre-cracking pipe 423. The pre-cracking pipe includes a pipe body 4231 and a fracturing point 4232 arranged on the pipe body. The fracturing point is electrically connected to the central control device 60. When in use, the carbon dioxide storage tank transports carbon dioxide to the first pressurizing device, forms supercritical carbon dioxide (i.e., a state of high pressure) in the first pressurizing device, and transports it to the pre-cracking pipe. The pre-cracking pipe consists of a pipeline and a fracturing point. Whether the fracturing point is opened is controlled by the central control device. During operation, the lifting mechanism is started to transport the carbon dioxide pre-cracking device to the hole drilled by the water jet device. The fracturing point is opened, a large amount of carbon dioxide high-pressure gas is ejected, and microcracks are formed in the rock.

[0044] Reference Fig.11 Furthermore, the water jet device 430 includes 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 also includes a positioning mechanism, and the positioning mechanism is electrically connected to the central control device 60. Specifically, the positioning mechanism can be a GPS positioning device. When working, water is directly obtained from seawater, and is converted into high-pressure water after being pressurized by the second pressurizing device, and then transported to the high-pressure water gun. The high-pressure water gun is connected to the positioning mechanism, which can obtain GPS positioning information in real time and transmit it to the central control device, and the central control device realizes the control of the size and direction of the hole.

[0045] Furthermore, the rock drilling hammer device 410 includes a rock drilling hammer 411, which is connected to a pulley via a steel cable, and the pulley is connected to a lifting mechanism, which is controlled by a central control device. When the rock drilling hammer system starts the operation, the lifting mechanism drives the rock drilling hammer to perform free fall motion; after the operation is completed, the lifting mechanism starts and retracts the rock drilling hammer to restore it to its original height.

[0046] Reference Figure 3 , Figure 4As a preferred technical solution of this embodiment, a cavity is provided inside the ring body 510, and a sliding ring 511 is slidably provided inside the cavity. A sliding groove 512 is provided on the top of the ring body and is locally distributed along the circumference of the ring body. A sliding block 513 is slidably connected in the sliding groove, and the sliding block is fixedly connected to the sliding ring 511. The pulley 520 is rotatably provided on the sliding block 513 through a bracket 540. It should be noted that the sliding groove in this embodiment is locally distributed along the circumference of the top of the ring body, that is, the sliding groove is not a complete ring. In this way, when the sliding ring slides in the cavity of the ring body, it can drive the sliding block to slide in the sliding groove, that is, the sliding block and the pulley thereon can be locally rotated along the ring body, so as to facilitate moving the rock drilling hammer device 410, the carbon dioxide pre-cracking device 420 and the water jet device 430 to a suitable position.

[0047] It should be noted that, in the present embodiment, in order to improve the convenience of adjusting the rock drilling hammer device 410, the carbon dioxide pre-cracking device 420 and the water jet device 430, when installing the ring body, the portion of the ring body without the sliding groove can be arranged on the side close to the hull, so that the portion of the ring body with the sliding groove is located on the outer side of the hull, so that the azimuth adjustment of the aforementioned rock drilling hammer device 410, the carbon dioxide pre-cracking device 420 and the water jet device 430 can be facilitated.

[0048] Reference Figure 5 Furthermore, in order to achieve stable sliding of the sliding ring in the inner cavity of the ring body, a guide ridge 514 is provided at the bottom of the inner cavity, and correspondingly, a guide groove matching the guide ridge is provided at the bottom of the sliding ring 511. At the same time, in order to drive the rotation of the sliding ring, a power mechanism for driving the sliding ring 511 to move is also provided on the outer wall of the guide rod 30. Specifically, the power mechanism includes a motor 551 fixed to the outer wall of the guide rod, a driving gear 552 arranged at the output end of the motor, and a driven gear 553 arranged on the inner side of the sliding ring and meshing with the driving gear. When in use, the driving gear is driven to rotate under the drive of the motor, and the driving gear then drives the driven gear meshing with it to rotate. Since the driven gear is fixedly connected to the inner side of the sliding ring, when the driven gear rotates, it will synchronously drive the sliding ring to rotate in the inner cavity of the ring body, thereby achieving stable movement of the sliding ring.

[0049] Reference Figure 6 , Figure 7As a preferred technical solution of this embodiment, the outer wall of the ring body 510 is slidably connected with 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 fixedly provided 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 unfolded or retracted along the outer wall of the ring body to realize 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, the mounting block can be driven to slide along the groove synchronously.

[0051] Reference Figure 8 , Fig. 9 , further, the outer wall of the guide ring 517 is slidably connected with a plurality of support rods 518, and a support ring 519 is fixedly arranged 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 or separated from each other, and the outer wall of the mounting block 515 is fixedly provided with a magnetic suction cylinder 521, so that the support rod 518 close to the mounting block 515 can be magnetically attracted or separated from the mounting block when being magnetically attracted or separated from the magnetic suction cylinder;

[0052] Furthermore, each of the support rods 518 is provided with a limiting column 522 at the bottom, and correspondingly, a plurality of limiting seats 523 are arranged at intervals along the extension range of the sliding groove 512 on the outer wall of the ring body 510, and the limiting seats are used in conjunction with the limiting columns. Specifically, the lengths of the plurality of limiting columns 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, and the matching surfaces of the limiting columns 522 and the limiting seats 523 are provided with matching magnetic surfaces 5 24. In this embodiment, there are three limit columns and three limit seats, and the limit seats are evenly arranged on the outer wall of the ring body along the circumference of the sliding groove. When in use, the steel cable is transported from the output end of the lifting mechanism to the direction of the ring body, and the steel cable is placed in the support ring. At the same time, multiple support rods are adsorbed together by magnetic blocks, and the adsorbed support rods are located on the side wall of the mounting block. When the pulley needs to be moved to the side of the ring body away from the hull for lifting operations, the motor can be used to drive the active gear to rotate, and the active gear can then drive the driven gear to rotate, and the driven gear can then drive the sliding ring to slide in the inner cavity of the ring body, so as to drive the sliding block to slide, and the sliding block can then drive the pulley to slide. Since the sliding block will synchronously drive the mounting block to slide along the guide ring, the mounting block drives multiple support rods and the support ring to slide when sliding. At this point, the sliding block, pulley, steel cable and other components can be moved along the inner side of the sliding groove - the outer side of the sliding groove - the inner side of the sliding groove. In this moving process, the support rod will move to the corresponding limit seat position when moving with the mounting block, so that The corresponding limit column is magnetically attracted to the limit seat, thereby releasing the limit column together with the support rod and the support ring at the position of the limit seat, so that the released support ring can be used to sort out and support the steel cable, avoiding confusion of the released steel cable and facilitating the retrieval of the steel cable; when the steel cable needs to be retracted to the lifting mechanism, the mounting block slides with the sliding block, and the magnetic suction cylinder thereon is used to absorb the limit column released to the limit seat, and multiple limit columns and support rods are absorbed together. At the same time, the lifting mechanism retracts the steel cable along the support ring.

[0053] In this embodiment, the limiting posts on the support rod and the limiting seats on the outer wall of the ring body are different, and each limiting post is matched with its corresponding limiting seat, that is, a certain limiting post can only be magnetically matched with the limiting seat at its corresponding position, thereby realizing the release or retraction of the support ring.

[0054] It should be noted that a certain direction in this embodiment can be a clockwise direction along the ring body or a counterclockwise direction along the ring body, and no excessive restrictions are made here.

[0055] When in use, the central control device is started, the high-pressure water gun is adjusted to a suitable position through the pulley, the second pressurizing device is started to pressurize, and a high-pressure water flow is ejected to break the rock to form a small hole. After the water jetting work 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 to the inside; then the central control device is started, the lifting mechanism drives the pulley to extend the carbon dioxide fracturing tube into the above-mentioned small hole, and the carbon dioxide storage tank inputs the stored carbon dioxide into the first pressurizing device, and after forming supercritical carbon dioxide, it is input into the fracturing tube. The central control device controls the detonation, and a large amount of high-pressure gas is ejected to form microcracks; after the carbon dioxide fracturing operation is completed, the lifting mechanism drives the pulley to restore the carbon dioxide fracturing tube to its original position, and the central control device controls the pulley and the carbon dioxide fracturing tube to rotate along the guide rod and rotate to the inside; then, the lifting mechanism is started to drive the rock drilling hammer to perform free fall motion to break through the rock full of microcracks. After the above operation is completed, the lifting mechanism drives the rock drilling hammer to return to its original position. This cycle is repeated to achieve the 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.
