Description

Technical Field

[0001] The present invention relates to the technical field of floating vessel pump stations, in particular to an amphibious floating vessel pump station device suitable for open-pit sunken mining in mines. Background Art

[0002] In my country, open-pit mining is gradually transitioning to underground operations. As mining depth increases, this shift in methods from open-pit to underground has led to an increasing problem of water hazards. During mining operations, these activities disrupt previously stable aquicludes, open up water-bearing fault fracture zones, and disrupt the existing water pressure balance underground. Large amounts of groundwater then surge into the mining area, causing flooding disasters. Simultaneously, the influx of natural rainfall exacerbates flooding, posing a significant threat to mining operations. Impaired drainage can lead to serious problems such as collapse and flooding of mine deposits, significantly hindering mine operations and potentially causing casualties and significant property losses.

[0003] Floating pump stations are a common solution to these complex drainage challenges. However, existing pontoon structures have significant drawbacks: they are bulky, expensive to manufacture, and lack mobility. They are difficult to relocate during open-pit pit bench mining and are unable to meet relocation requirements. Furthermore, they struggle to cope with peak drainage demands during emergencies such as torrential rainstorms and fault bursts. These factors have severely hampered their widespread adoption, hindering mine drainage capabilities from keeping pace with growing demand.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide an amphibious floating pump station device suitable for open-pit mining in mines to solve the problems existing in the above-mentioned prior art. It has a small size and is easy to transfer. It can also cope with the peak drainage needs of sudden events such as rainstorms, fault bursts, etc.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-11As shown, this embodiment provides an amphibious floating ship pump station device for open-pit depression mining in mines, including a working main ship 1, several working auxiliary ships 2 and several functional ships 3. The working main ship 1, several working auxiliary ships 2 and several functional ships 3 can constitute a floating ship combination group, wherein the volume and mass of the working main ship 1 are greater than the volume and mass of two working auxiliary ships 2 and one functional ship 3. The purpose of this setting is to enable the working main ship 1 to serve as the center of gravity of the entire floating ship combination group, so as to play a positioning role for the entire floating ship combination group, which is the key to ensuring the accurate operation of the entire floating ship combination group. The functional vessel 3 provides the necessary supplies for the main working vessel 1. During actual operation, the main working vessel 1 and the auxiliary working vessel 2 are necessary. Generally, two auxiliary working vessels 2 are provided. Under normal operating conditions, only one main working vessel 1 and one auxiliary working vessel 2 are required for operation. The other auxiliary working vessel 2 serves as a backup vessel. When the active auxiliary working vessel 2 fails, the other auxiliary working vessel 2 can be activated to operate, or the auxiliary working vessels 2 can be used at 50% of their full capacity to ensure normal operation. In the event of an emergency, the two auxiliary working vessels 2 can operate simultaneously to achieve full capacity, and even the two backup auxiliary working vessels 2 can be urgently mobilized to connect with the existing auxiliary working vessel 2. When the main working vessel 1 in the water is low on supplies and needs to transport required items or equipment, the functional vessel 3 can be urgently mobilized. Both the auxiliary working vessel 2 and the functional vessel 3 can be detachably connected to the side wall of the main working vessel 1 through a hull connection device 4. When there are two or more auxiliary working vessels 2 or functional vessels 3 on the same side, adjacent auxiliary working vessels 2 and adjacent functional vessels 3 can also be connected through the hull connection device 4. The main working vessel 1, auxiliary working vessel 2, and functional vessel 3 are all equipped with running gear at their lower ends. These running gears allow them to maneuver over land, shore, or shallow water. After completing operations such as water pumping and pressurization, when the water level drops below the waterline, the running gear serves as a stable support structure, ensuring the stability of the main working vessel 1, auxiliary working vessel 2, and functional vessel 3 during operations. The running gear responds promptly to water level fluctuations, keeping the main working vessel 1, auxiliary working vessel 2, and functional vessel 3 stable and preventing tilting or swaying caused by falling water levels, thus ensuring smooth operations such as water pumping and pressurization. When the floating vessel reaches land, the running gear enables smooth movement on the land surface. The running gear can utilize a conventional wheeled structure, with a rotating axle mounted at each end of the lower end of the main working vessel 1, auxiliary working vessel 2, and functional vessel 3. Each axle is connected to a wheel at each end, allowing the main working vessel 1, auxiliary working vessel 2, and functional vessel 3 to maneuver freely over land.The wheeled structure is characterized by flexible mobility and low resistance, and can easily adapt to different land terrains, such as flat roads and rugged mountain roads. It greatly improves the maneuverability and flexibility of the main working vessel 1, the auxiliary working vessel 2, and the functional vessel 3, and enables the main working vessel 1, the auxiliary working vessel 2, and the functional vessel 3 to freely switch between water and land. Of course, in addition to the traditional wheeled structure, those skilled in the art can also replace the wheels with universal wheels or crawler chassis structures, and are not limited to just one type. Those skilled in the art can choose according to actual needs. The main working vessel 1 is connected to a connecting truss 5. The end of the connecting truss 5 away from the main working vessel 1 is connected to the shore. The connecting truss 5 is used to limit the position of the main working vessel 1, thereby limiting the range of movement of the floating vessel assembly. Since the main working vessel 1 connected to the connecting truss 5 is relatively small, the connecting truss 5 is also optimized to effectively reduce its overall weight. This not only reduces the cost of material use, but also improves the overall performance of the main working vessel 1. The lighter connecting truss 5 makes the main working vessel 1 easier to move and operate, reduces energy consumption, and improves energy efficiency.

[0037] In actual use, since the traditional large and integrated floating pump station is divided into multiple small modular floating single bodies according to function, both the manufacturing cost and volume are much smaller than the traditional floating pump station. Due to the small size, and the lower ends of the main working ship 1, the auxiliary working ship 2 and the functional ship 3 are equipped with walking devices, they can be easily transferred. It should be noted that when transferring, the main working ship 1, the auxiliary working ship 2 and the functional ship 3 need to be separated from each other to form separate hulls, so as to facilitate the transfer.

[0038] In this embodiment, if Figure 2 As shown, the hull connecting device 4 includes a first direction swinging device 401, a hull spacing buffer telescopic device 402 and a second direction swinging device 403 connected in sequence, wherein the end of the first direction swinging device 401 away from the hull spacing buffer telescopic device 402 is used to be connected to the working main ship 1 through bolts, and the end of the second direction swinging device 403 away from the hull spacing buffer telescopic device 402 is used to be connected to the working auxiliary ship 2 or the functional ship 3 through bolts.

[0039] The first-direction swing device 401 and the second-direction swing device 403 have the same structure. Both ends of the first-direction swing device 401 and the second-direction swing device 403 can rotate relative to each other. However, the difference between the two is that the swing direction of the two ends of the first-direction swing device 401 is perpendicular to the swing direction of the two ends of the second-direction swing device 403. Specifically, the two ends of the first-direction swing device 401 can swing left and right in the horizontal direction, and the two ends of the second-direction swing device 403 can swing up and down in the vertical direction; or, the two ends of the first-direction swing device 401 can swing up and down in the vertical direction, and the two ends of the second-direction swing device 403 can swing left and right in the horizontal direction. By setting the first-direction swing device 401 and the second-direction swing device 403, the working main ship 1 and the working auxiliary ship 2 (or the functional ship 3) can be deflected in an up, down, left, and right angle manner.

[0040] The two ends of the hull spacing buffer telescopic device 402 can be close to or away from each other, so as to adjust the spacing between the working main ship 1 and the working auxiliary ship 2 (or functional ship 3), and play a damping and buffering role between them.

[0041] In this embodiment, if Figure 3-Figure 4 As shown, the first direction swing device 401 includes two swing members 4011 and an intermediate hinge 4012. The cross-section of the swing member 4011 is T-shaped, and the cross-section of the intermediate hinge 4012 is I-shaped. The adjacent ends of the two swing members 4011 are rotatably connected to the middle grooves on both sides of the intermediate hinge 4012 through a swing pin 4013. One end of the swing pin 4013 can pass through the swing member 4011 and the intermediate hinge 4012 in sequence, and a swing shaft retaining ring 4014 is sleeved on the outer side of one end of the swing pin 4013 to prevent the swing member from rotating. Figure 3 Taking the middle direction as an example, the swing pin 4013 passes through the swing member 4011 and the middle hinge 4012 from bottom to top, and the big head end of the swing pin 4013 is against the bottom of the middle hinge 4012, thereby preventing it from moving further upward. The swing pin 4013 passes through the middle hinge 4012 and one end of the swing member 4011 and is plugged with a limiting cotter pin 4015. The plug-in direction of the limiting cotter pin 4015 is perpendicular to the axial direction of the swing pin 4013, and the limiting cotter pin 4015 is against the swing shaft retaining ring 4014. The purpose of this setting is to enable the limiting cotter pin 4015 to be used to prevent the swing shaft retaining ring 4014 from moving along the axial direction of the swing pin 4013.

[0042] In actual use, since the swing members 4011 on both sides are hinged to the middle hinge member 4012 through the swing pin 4013, the swing members 4011 on both sides can swing with the corresponding swing pin 4013 as the swing center, thereby realizing the relative swing of the two ends of the first direction swing device 401 (and the second direction swing device 403).

[0043] It should be noted that the axial direction of the swing pin 4013 in the first direction swing device 401 is perpendicular to the axial direction of the swing pin 4013 in the second direction swing device 403, thereby achieving the technical effects of one swinging up and down in the vertical direction and one swinging left and right in the horizontal direction.

[0044] In addition, due to the volume limitation of the swing member 4011 and the middle hinge 4012, the swing range of the swing member 4011 is about 5°. When the swing member 4011 exceeds 5°, it will abut against the middle hinge 4012, thereby limiting its further swing.

[0045] In this embodiment, if Figure 5 As shown, the hull spacing buffer telescopic device 402 includes two telescopic positioning bases 4021, a telescopic limiting shaft 4022, and a compression spring 4023. The telescopic positioning base 4021 is a cylindrical structure with a T-shaped cross-section, comprising a small-diameter cylindrical structure and a large-diameter cylindrical structure fixed to each other, with the large-diameter cylindrical structure having a larger diameter than the small-diameter cylindrical structure. Each of the two telescopic positioning bases 4021 has a telescopic limiting hole at its center. The ends of the telescopic limiting shaft 4022 are slidably connected to the two telescopic limiting holes. The adjacent ends of the two telescopic limiting holes are provided with a reducing structure, the inner diameter of which is smaller than that of the telescopic limiting hole. A limiting block is provided at each end of the telescopic limiting shaft 4022. The diameter of the limiting block is larger than the inner diameter of the reducing structure and smaller than the inner diameter of the telescopic limiting hole, thereby ensuring that the telescopic limiting shaft 4022 always slides in the two telescopic limiting holes and does not fall out. A compression spring 4023 is sleeved on the outer sides of the small-diameter cylindrical structures of the two telescopic positioning bases 4021 , and both ends of the compression spring 4023 are respectively pressed against the large-diameter cylindrical structures of the two telescopic positioning bases 4021 .

[0046] When the distance between the working main ship 1 and the working auxiliary ship 2 (or functional ship 3) becomes larger, the two telescopic positioning bases 4021 in the corresponding hull spacing buffer telescopic device 402 will move away from each other, and at the same time, the compression spring 4023 is in an extended state. When the limit blocks at both ends of the telescopic limit shaft 4022 respectively counteract the corresponding reduced diameter structures, at this time, Figure 5As shown, the hull spacing buffer and telescopic device 402 is in its longest position. When the distance between the main working vessel 1 and the auxiliary working vessel 2 (or the functional vessel 3) decreases, the two telescopic positioning bases 4021 in the corresponding hull spacing buffer and telescopic device 402 move closer to each other, and the compression spring 4023 is in a contracted state. When the adjacent ends of the two telescopic positioning bases 4021 abut against each other, the hull spacing buffer and telescopic device 402 is in its shortest position.

[0047] In this embodiment, if Figure 2 As shown, an extension tube 404 is connected to the end of the second direction swing device 403 away from the hull spacing buffer telescopic device 402, and the end of the extension tube 404 away from the second direction swing device 403 can be fixed to the corresponding working auxiliary ship 2 or functional ship 3 through a flange.

[0048] The reason why the extension tube 404 is provided is that Figure 1 It can be seen that whether it is the main working vessel 1, the auxiliary working vessel 2 or the functional vessel 3, they all include a hull structure and a deck structure. From a bird's-eye view, the area of ​​the deck structure is larger than the hull structure. When installing the hull connecting device 4, it needs to be installed on the outer wall of the hull structure. However, due to the large area of ​​the deck structure, the distance between the deck structures of the two pontoons is smaller than the hull structure during the connection process of the two pontoons. In this way, the deck structures of the two pontoons may collide with each other. Moreover, if the distance is too small, it is not conducive to the installation of the hull connecting device 4 by the workers. Therefore, an extension pipe 404 is installed on the outer wall of the auxiliary working vessel 2 or the functional vessel 3 to increase the distance between the two pontoons to be connected and improve the safety of the workers during installation.

[0049] In this embodiment, all functional ships 3 include several reinforcement ships and / or several energy supply ships, that is, they may include only several reinforcement ships, or only several energy supply ships, or include several reinforcement ships and several energy supply ships.

[0050] The reinforcement vessel provides support for the entire pontoon fleet, primarily providing additional drainage capacity when demand increases or replacing damaged auxiliary vessel 2 requiring repair. The reinforcement vessel carries a backup pump unit consisting of multiple pumps, capable of providing robust drainage capacity based on actual demand. Its structure and functionality are essentially identical to auxiliary vessel 2, allowing for easy replacement and coordination during operations, enhancing the flexibility and reliability of the entire system. When reinforcement is not required, it can independently serve as a "fixed pump station" at a temporary location on land.

[0051] The energy supply vessel carries energy supplies, providing them to the main working vessel 1. These supplies include, but are not limited to, diesel fuel, batteries, and other energy resources, ensuring that the main working vessel 1 will not experience energy shortages during extended operations. Furthermore, the energy supply vessel also functions as the main working vessel 1, offering energy conversion and distribution capabilities. This allows for efficient energy utilization based on the energy needs of different floating vessels, improving overall system efficiency and operational sustainability.

[0052] In this embodiment, a truss hinge seat 6 is provided on the working main ship 1 and the shore, and the two ends of the connecting truss 5 are respectively fixed on the two truss hinge seats 6. The reason why the two ends of the connecting truss 5 are set on the truss hinge seats 6 is that, during the actual working process, the water level may change continuously. As the water level changes continuously, the inclination state of the connecting truss 5 will also change continuously, so it is necessary to connect it to the truss hinge seat 6 to adapt to the position change of the connecting truss 5.

[0053] The truss hinge seat 6 on the shore is fixed on the portal frame 7 or the fixed base 8, and different fixing positions are adopted according to different shore environments.

[0054] If the shore is in a state of quicksand, Figure 6-Figure 7 As shown, it is necessary to cast a concrete positioning pile (i.e., a portal frame 7) on the shore, and then fix the truss hinge seat 6 on the shore to the portal frame 7, so as to ensure the installation stability of the truss hinge seat 6.

[0055] If the shore is the wall of a mine, Figure 8 As shown, the fixed base 8 is fixed to the mountain wall through the fixed anchor rod 9, and then the truss hinge seat 6 is fixed to the fixed base 8, thereby ensuring the installation stability of the truss hinge seat 6.

[0056] In this embodiment, the specific structure of the truss hinge seat 6 is as follows: Figure 9-10 As shown, the truss hinge base 6 includes an upper support plate 601 and a lower support plate 603. The upper support plate 601 is located above the lower support plate 603. An upper hinge lug 602 is provided on either side of the lower end of the upper support plate 601, and a lower hinge lug 604 is provided on either side of the upper end of the lower support plate 603. The two upper hinge lugs 602 are located inside the two lower hinge lugs 604. The upper hinge lugs 602 and lower hinge lugs 604 on the same side are hingedly connected by a hinge shaft 606. A cylindrical support tube 605 is hingedly connected to the two hinge shafts 606. The support tube 605 is located inside the two upper hinge lugs 602, thereby enhancing the support force of the truss hinge base 6 on the connected trusses 5.

[0057] During actual installation, the lower support plate 603 can be fixed to the main working vessel 1 or the shore by bolts, and the upper surface of the upper support plate 601 is used to install the connecting truss 5.

[0058] In addition, it should be noted that due to the volume limitations of the upper support plate 601 and the lower support plate 603, the upper support plate 601 cannot rotate 360°. If in some cases its rotation angle cannot meet actual needs, the lower surface of the lower support plate 603 can be installed at an angle on the working main ship 1.

[0059] In this embodiment, a main control module and a power supply module are provided on the working main ship 1. The main control module is a controller on the working main ship 1, which can be specifically a control cabinet. The power supply module provides power to the main control module and other equipment that requires electricity. The power supply module includes a diesel generator set, a UPS power supply system and a city power supply system. It adopts three common power supply methods to ensure the stability and reliability of the energy supply. Even if there is a problem with one of the power supply lines, the other two can be supplemented in time to ensure the normal operation of the entire floating ship combination group and reduce the risk of operation interruption due to power outages. The main control module and the power supply module are electrically connected. In addition, the main control module is also electrically connected to the control terminal on the shore. The control terminal can be a control host. In this way, the staff only needs to operate the main control module on the shore.

[0060] In addition, the working auxiliary ship 2 is equipped with a secondary control module and a secondary pump group. The secondary control module is a control cabinet, and the secondary pump group includes multiple drainage pumps. The secondary pump group and the main control module are both electrically connected to the secondary control module. The staff can directly control the operation of the secondary pump group through the secondary control module. They can also issue commands to the main control module, which are transmitted to the secondary control module through the main control module, and then control the operation of the secondary pump group through the secondary control module. In this way, only the main control module is required to centrally control each working auxiliary ship 2 and functional ship 3, achieving efficient and accurate operation control. This remote control function not only improves the safety of the operation, but also greatly improves work efficiency and avoids the tediousness and risks of manual operation.

[0061] In this embodiment, if Figure 11 As shown, the working main ship 1 is provided with several main water inlet pipes 101, a collecting pipe 102 and at least one main water outlet pipe 103, wherein the outlet end of each main water inlet pipe 101 is connected to the water inlet end of the collecting pipe 102, the outlet end of the collecting pipe 102 is connected to the water inlet end of the main water outlet pipe 103, and the outlet end of the main water outlet pipe 103 is connected to the shore, so that the pumped water is discharged to the shore.

[0062] The working auxiliary ship 2 and the reinforcement ship in the functional ship 3 are provided with an auxiliary water suction pipe 201, a first auxiliary water outlet pipe 202 and a second auxiliary water outlet pipe 203. The outlet end of the auxiliary water suction pipe 201 is connected to the water inlet end of the auxiliary pump group, and the outlet end of the auxiliary pump group is respectively connected to the water inlet end of the first auxiliary water outlet pipe 202 and the water inlet end of the second auxiliary water outlet pipe 203. The outlet end of the first auxiliary water outlet pipe 202 is connected to the water inlet end of the main water inlet pipe 101, so that the water pumped up by the working auxiliary ship 2 and the reinforcement ship is discharged to the collecting pipe 102 on the working main ship 1, or the water pumped up by the working auxiliary ship 2 and the reinforcement ship can be directly connected to the shore through the outlet end of the second auxiliary water outlet pipe 203.

[0063] When working, the auxiliary suction pipe 201 on the working auxiliary ship 2 (including the reinforcement ship if there is one) performs water absorption work, and the absorbed water can flow into the collecting pipe 102 through the first auxiliary outlet pipe 202 and the main water inlet pipe 101, and then be discharged to the shore through the main outlet pipe 103.

[0064] Through the centralized processing of water discharged from the working auxiliary ship 2 (and reinforcement ship if there is one) by the working main ship 1, the number of shore outlet pipelines can be reduced from the number of working auxiliary ships 2 to the number of main outlet pipes 103, greatly reducing the complexity of pipeline laying and construction costs.

[0065] In addition, the working auxiliary ship 2 has a dual water supply mode: in the centralized water supply mode, the water discharged from the working auxiliary ship 2 is collected into the working main ship 1 through the first auxiliary water outlet pipe 202, and is uniformly transported through the main water outlet pipe 103; in the independent water supply mode, the working auxiliary ship 2 can be directly connected to the shore pipeline through the second auxiliary water outlet pipe 203 to meet the diverse working conditions such as local area drainage.

[0066] Furthermore, if the water delivery distance is too long, a reinforcement vessel can be towed to the shore and the spare pump set on the reinforcement vessel connected to the delivery pipe, thus achieving long-distance multi-stage pressurized delivery. This can improve drainage pressure and efficiency, ensuring that drainage tasks can be completed quickly and effectively in various environments.
