Description

Technical Field

[0001] The invention relates to the technical field of open-pit sunken mining, and in particular to a large rotary floating ship pump station structure. Background Art

[0002] As open-pit mining continues to advance deeper, the mining method has gradually shifted from open-pit to underground. This shift has led to increasingly severe water hazards: mining operations destroy previously stable aquicludes, penetrate water-bearing fault fracture zones, and disrupt the original water pressure balance underground, causing large amounts of groundwater to flow into the foundation pits within the mining area, triggering flooding disasters. Furthermore, the influx of natural rainfall into the foundation pits further exacerbates the flooding, posing a significant safety hazard to mining operations. Poor drainage can easily lead to serious accidents such as underground mine collapses and flooding of mineral deposits, which not only hinder normal mine production but can also cause casualties and significant property damage.

[0003] To drain the water from the foundation pit promptly, a common solution is to use a floating pump station. Traditional floating pump stations are typically installed on the shore, requiring a reinforced concrete structure to be cast on a sloped bank. A truss rocker arm connects the floating pontoon to the reinforced concrete structure. However, due to the limited installation location and rotation angle range, traditional floating pump stations are unable to effectively cope with large water level fluctuations. High water levels can easily flood the floating pontoon, making them difficult to adapt to complex hydrological conditions. Summary of the Invention

[0004] In view of this, the present invention provides a large rotary floating vessel pump station structure to solve the problem that the existing floating vessel pump station is limited by the installation position, the rotation angle range is small, it is difficult to effectively cope with large water level changes, and it is easy to cause the floating vessel to be flooded.

On the one hand, the floating pump station components can be located near the center of the water area, and the movement trajectory of the transverse trusses between the vertical trusses and the floating pump station components will not interfere with the shore, so that the floating pump station components can swing at a large angle of at least 120° relative to the vertical trusses with the transverse trusses, which can better adapt to large water level changes, thereby effectively avoiding the flooding of the floating pump station components, and thus helping to improve the adaptability and safety of the large-rotating floating pump station structure under complex hydrological conditions; on the other hand, it can reduce the complexity of construction, reduce construction links, and save time and costs.

[0052] The following combination Figures 1 to 11 , describing embodiments of the present invention.

[0053] According to an embodiment of the present invention, a large rotary floating pump station structure is provided, which is used to drain water from the water area formed in the foundation pit of an open-pit mine. The large rotary floating pump station structure includes a vertical truss 100, the bottom end of the vertical truss 100 is used to be connected to the bottom foundation in the center of the water area, the top end of the vertical truss 100 is rotatably connected to a transverse truss 200, and the end of the transverse truss 200 facing away from the vertical truss 100 is movably connected to a floating pump station assembly, which is used to drain water from the water area.

[0054] The large rotary floating pump station structure of this embodiment sets a vertical truss 100 on the bottom foundation in the center of the water area, and uses the vertical truss 100 to replace the reinforced concrete structure of the traditional floating pump station to provide vertical support force, ensuring that the floating pump station assembly can be stably raised and lowered and stand on the water surface. On the one hand, the floating pump station assembly can be located near the center of the water area, and the movement trajectory of the transverse truss 200 located between the vertical truss 100 and the floating pump station assembly will not interfere with the shore, so that the floating pump station assembly can swing at a large angle of at least 120° relative to the vertical truss 100 with the transverse truss 200, which can better adapt to large water level changes, thereby effectively avoiding the floating pump station assembly from being flooded, and thus helping to improve the adaptability and safety of the large rotary floating pump station structure of this embodiment under complex hydrological conditions; on the other hand, it can reduce the complexity of construction, reduce construction links, and save time and cost.

[0055] It should be noted that the present embodiment utilizes a vertical truss 100 to replace the reinforced concrete structure of a traditional floating pump station. The vertical truss 100 is assembled by prefabricated components in the factory. Compared with the traditional floating pump station, which adopts an on-site casting method to cast a reinforced concrete structure on the shore, the construction process is complicated, requires professional equipment and personnel, and is costly. The "assembly" construction and standardized truss design of the present embodiment can save about 50% of the construction time, significantly improve the construction efficiency, and reduce the impact on the normal production and operation of the mine.

[0056] It should be noted that the floating pump station assembly of this embodiment can swing at a large angle of at least 120° relative to the vertical truss 100 along with the transverse truss 200. When faced with severe weather such as underground water gushing, heavy rain, etc., a large amount of water enters the foundation pit, causing the water level in the water area to rise rapidly in a short period of time, the connection nodes between the vertical truss 100 and the transverse truss 200 and the connection nodes between the transverse truss 200 and the floating pump station assembly work together to ensure the stable lifting and lowering operation of the floating pump station assembly, avoid drainage interruption and flooding of the hull, and ensure the safety of the surrounding area.

[0057] It should be noted that the transverse truss 200 located between the vertical truss 100 and the floating vessel pump station assembly adopts a standardized truss design, which enhances the supporting stability of the entire structure and is conducive to improving the anti-tilt capability.

[0058] It should be noted that the large-angle swing of at least 120° means that the angle between the transverse truss 200 when the floating vessel pump station assembly rises to the extreme position as the water level rises and the transverse truss 200 when the floating vessel pump station assembly falls to the extreme position as the water level falls is at least 120°.

[0059] It can be understood that the floating boat pump station assembly of this embodiment is located near the center of the water area, away from the garbage located near the water surface near the shore, which is beneficial to reduce the blockage of the water suction pipeline and reduce maintenance costs.

[0060] It can be understood that this embodiment is located near the center of the water area and is far away from the surrounding mines, which meets the "bombing avoidance" requirements, ensures equipment safety, and improves the safety and continuity of mining operations.

[0061] It can be understood that in this embodiment, the transverse truss 200 is located near the center of the water area, rather than near the shore, and the transverse truss 200 relies on the vertical truss 100 located in the center of the water area to provide vertical support force. Therefore, the transverse truss 200 will not interfere with the shore. The transverse truss 200 can swing freely relative to the vertical truss 100, so that the floating boat pump station assembly can swing at a large angle of at least 120° relative to the vertical truss 100 as the transverse truss 200 swings relative to the vertical truss 100, so as to better adapt to large water level changes.

[0062] It can be understood that during the open-pit mining process, groundwater flows into the foundation pit of the open-pit mine and rainwater injected by rainfall accumulates to form a water area. Therefore, the bottom foundation in the center of the water area is actually the rock of the mine (i.e., the ground), which facilitates the construction and assembly of the vertical truss 100.

[0063] It should be noted that the traditional floating pump station relies on the reinforced concrete structure cast on the shore with a certain slope to provide vertical support, that is, there is at least a distance between the reinforced concrete structure and the water area. Therefore, in order to connect the pontoon of the traditional floating pump station with the reinforced concrete structure, a longer and bulky transverse truss 200 is required to pass through the area between the reinforced concrete structure and the water area before it can be connected to the pontoon to meet the lifting requirements; while the present application directly installs the vertical truss 100 on the bottom ground foundation in the center of the water area, and only a smaller transverse truss 200 is needed to connect the vertical truss 100 with the floating pump station assembly to meet the same lifting requirements, so that in the process of installing the large rotary floating pump station structure of this embodiment, no complicated lifting equipment and professionals are required, and ordinary workers can quickly complete the assembly, greatly reducing the construction links and shortening the construction time.

[0064] It should be noted that the traditional floating pump station relies on the reinforced concrete structure cast on the shore with a certain slope to provide vertical support. Therefore, the pontoon of the traditional floating pump station can only be installed near the shore, and the vertical projection of the transverse truss 200 connecting the pontoon of the traditional floating pump station to the reinforced concrete structure will fall on the shore. If the transverse truss 200 of the traditional floating pump station swings downward too much, it will interfere with the shore. Therefore, the rotation angle range of the traditional floating pump station is small, especially the limited descent position leads to the interruption of discharge before the water in the deeper water area is completely discharged, and the surrounding safety cannot be guaranteed.

[0065] Specifically, the vertical truss 100 is formed using a lattice steel column structure. The vertical truss 100 is constructed using high-strength, corrosion-resistant materials and is designed based on scientific mechanical principles. The unique structure and rational rod layout of the lattice steel column structure enable it to have a load-bearing capacity far exceeding that of other supporting structures, capable of withstanding greater pressure and tension. This superior load-bearing capacity provides a solid guarantee for the stable operation of the floating pump station components. Even in complex geological conditions and harsh water environments with turbulent water flows and drastic water level fluctuations, the vertical truss 100 can provide stable and reliable support and positioning for the floating pump station components, ensuring the long-term stable operation of the large-slewing floating pump station structure of this embodiment. At the same time, the components of the vertical truss 100 can be prefabricated in a standardized manner in a factory. During the factory production process, advanced equipment and a strict quality control system are utilized to ensure that the dimensional accuracy, material properties, and other aspects of each component meet high standards. The standardized design makes the components universal and interchangeable, reducing errors and uncertainties in on-site construction.

[0066] Specifically, the transverse truss 200 is also formed by a lattice steel structure column structure.

[0067] More specifically, the vertical trusses 100 and the transverse trusses 200 are both configured to be detachable, and the components of the transverse trusses 200 or the vertical trusses 100 are quickly fastened and connected using bolts. On the one hand, this facilitates the rapid assembly of the transverse trusses 200 and the vertical trusses 100; on the other hand, it facilitates the disassembly, transfer, and reuse of the transverse trusses 200 or the vertical trusses 100.

[0068] like Figures 1 to 5As shown, in some embodiments, a floating pump station assembly includes a floating vessel and a pump station body 360. The floating vessel includes a main vessel 310 and two auxiliary vessels 320. The two auxiliary vessels 320 are arranged on either side of the main vessel 310, and each auxiliary vessel 320 is connected to the main vessel 310 via a connecting trestle 330. The main vessel 310 is provided with a mounting slot 311 at one end facing the transverse truss 200. A rotating shaft 340 is provided in the mounting slot 311. The transverse truss 200 is rotatably connected to the rotating shaft 340 via a half sleeve 350. The pump station body 360 is disposed on the floating vessel and is used to discharge water from the water area. This arrangement allows the main vessel 310 and the two auxiliary vessels 320 to form a combined floating vessel. On the one hand, this increases the floating vessel's anti-tilting ability. On the other hand, it can be transported separately, thereby facilitating transfer and movement, meeting the needs of frequent transfers in open-pit mining. At the same time, by providing a mounting groove 311 on the larger main ship 310, and the transverse truss 200 is rotatably connected to the rotating shaft 340 located in the mounting groove 311 through the half sleeve 350, both the vertical truss 100 and the transverse truss 200 can rotate relative to each other, and the transverse truss 200 and the floating vessel pump station assembly can rotate relative to each other for adaptive adjustment to avoid jamming, so that only one transverse truss 200 is needed to drive the floating vessel pump station assembly to smoothly perform a wide range of adaptive swinging and lifting with large changes in water level, and the structure is more simplified.

[0069] In a specific application, one end of the connecting pier 330 is detachably connected to the main ship 310 via bolts, and the other end is detachably connected to the auxiliary ship 320 via bolts.

[0070] like Figure 2 As shown, specifically, first connecting flanges 341 are provided at both ends of the rotary shaft 340, and the first connecting flanges 341 are connected to the surrounding wall of the mounting groove 311 via first bolts 342. With this arrangement, when the present embodiment is assembled for use, the first connecting flanges 341 need only be connected to the mounting groove 311 via the first bolts 342 to complete the rotational connection between the transverse truss 200 and the floating pump station assembly. When the present embodiment needs to be disassembled for transfer, the transverse truss 200 and the floating pump station assembly can be separated by simply removing the first bolts 342. The entire disassembly and assembly process is easy to operate, facilitating the flexible transfer of the present embodiment to meet the needs of sunken step mining operations in open-pit mines.

[0071] like Figure 1 、 Figure 2 and Figure 5As shown, specifically, a connecting rod 210 is provided between the transverse truss 200 and the half sleeve 350, and the end surfaces of the connecting rod 210 and the transverse truss 200 facing each other are respectively provided with a second connecting flange 220, and the two second connecting flanges 220 are connected by a second bolt 221. Through such a configuration, the second connecting flange 220 increases the contact area between the transverse truss 200 and the connecting rod 210, and improves the connection strength between the transverse truss 200 and the connecting rod 210; and the two second connecting flanges 220 are detachably connected into one body by the second bolt 221, thereby facilitating the disassembly and assembly of the transverse truss 200 and the connecting rod 210, and facilitating the transverse truss 200 and the connecting rod 210 to be prefabricated in the factory and then transported to the site for assembly.

[0072] In specific applications, the two second connecting flanges 220 are correspondingly penetrated by multiple second bolt holes, and the multiple second bolt holes are evenly spaced along the circumference of the connecting rod 210. The second bolt holes are used for the second bolts 221 to pass through; when the connecting rod 210 is assembled with the transverse truss 200, the second bolts 221 are passed through the corresponding second bolt holes and the second nuts are tightened.

[0073] Specifically, the cross-section of the connecting rod 210 is smaller than the cross-section of the transverse truss 200 .

[0074] like Figure 5 As shown, specifically, the half sleeve 350 includes a first half sleeve 351 and a second half sleeve 352, and the first half sleeve 351 and the second half sleeve 352 are detachably connected by a third bolt 353; the first half sleeve 351 and the second half sleeve 352 are respectively provided with a first arc groove and a second arc groove on the side facing each other, and when the first half sleeve 351 and the second half sleeve 352 are assembled, the first arc groove and the second arc groove form a circular through hole 354, and the circular through hole 354 matches the rotating shaft 340. Through such an arrangement, when it is necessary to assemble the half sleeve 350 and the rotating shaft 340, it is only necessary to place the first half sleeve 351 and the second half sleeve 352 against the outer peripheral surface of the rotating shaft 340, and make the rotating shaft 340 located in the circular through hole 354, and then use the third bolt 353 to connect the first half sleeve 351 and the second half sleeve 352 into one to complete the assembly; when it is necessary to separate the half sleeve 350 and the rotating shaft 340, it is only necessary to remove the third bolt 353, and the entire disassembly and assembly process is easy to operate; and the rotating shaft 340 can be removed separately for repair or replacement, reducing maintenance costs.

[0075] Specifically, a first mounting portion is horizontally extended at both ends of the first half sleeve 351, and a second mounting portion is horizontally extended at both ends of the second half sleeve 352. The first mounting portion and the second mounting portion are correspondingly penetrated by first bolt holes, and the first bolt hole matches the third bolt 353; a positioning portion 355 is provided at one end of the first half sleeve 351 facing the second half sleeve 352, and a positioning groove 356 is provided at the position of the second half sleeve 352 corresponding to the positioning portion 355, and the positioning groove 356 matches the positioning portion 355. When it is necessary to assemble the first half sleeve 351 and the second half sleeve 352 into an integrated half sleeve 350, it is only necessary to insert the positioning part 355 into the positioning groove 356 to ensure that the first bolt holes of the first half sleeve 351 and the second half sleeve 352 are aligned, and then the third bolt 353 is passed through the corresponding first bolt hole and the third nut is tightened to complete the assembly of the first arc groove and the second arc groove into a circular through hole 354 that matches the rotating shaft 340; when it is necessary to separate the half sleeve 350 and the rotating shaft 340, it is only necessary to remove the third nut from the third bolt 353 and take the third bolt 353 out of the corresponding first bolt hole. The entire disassembly and assembly process is easy to operate; and the rotating shaft 340 can be removed separately for repair or replacement, reducing repair costs.

[0076] In a specific application, a plurality of first bolt holes are provided, and the plurality of first bolt holes are arranged at equal intervals on the first mounting portion along the circumference of the connecting rod 210 .

[0077] More specifically, the first half sleeve 351 and the connecting rod 210 are integrally formed.

[0078] like Figure 2 As shown, specifically, two stoppers 343 are convexly formed on the outer surface of the rotating shaft 340. The two stoppers 343 are spaced apart along the axial direction of the rotating shaft 340, and the half sleeve 350 is disposed between the two stoppers 343. Through this arrangement, the two stoppers 343 serve to limit the half sleeve 350, preventing the half sleeve 350 from excessively moving along the axial direction of the rotating shaft 340 on the rotating shaft 340, ensuring that the floating vessel pump station assembly can smoothly and adaptably swing and rise and fall over a wide range with large changes in water level.

[0079] Specifically, the connecting pier 330 includes a shock-absorbing corrugated compensator, which can compensate for the axial and angular displacement of the connecting pier 330, and play a buffering role between the main ship 310 and the auxiliary ship 320, which is conducive to improving the stability of the floating pump station component in adapting to a large range of swinging and lifting with large changes in water levels.

[0080] like Figure 1 、 Figure 3 and Figure 4As shown, specifically, the bottom of the floating boat is provided with running wheels 370, and the length of the transverse truss 200 is greater than the length of the vertical truss 100, so that after all the water in the water area is drained, the floating boat pump station assembly can be lowered to abut the bottom of the open-pit mine foundation pit, so that the running wheels 370 abut against the ground for movement and transfer; it realizes amphibious use and meets the need for frequent site movement during mining.

[0081] Typically, mine foundations are solid, and simply installing the vertical truss 100 directly on the mine foundation can meet strength requirements. However, when this embodiment is applied to open-pit mines with relatively loose soil for drainage, if the vertical truss 100 is directly installed on the mine foundation, the connection strength may not meet the requirements. Therefore, to ensure that the vertical truss 100 provides stable vertical support, thereby ensuring that the floating pump station assembly can be stably raised and lowered on the water surface, a base pedestal 110 is provided at the bottom end of the vertical truss 100. More specifically, the base pedestal 110 is cast and formed on the mine foundation.

[0082] like Figures 6 to 9 As shown, in some embodiments, the floating boat pump station assembly includes a floating boat and a pump station body 360, the floating boat includes a main boat 310 and two auxiliary boats 320, the two auxiliary boats 320 are arranged on both sides of the main boat 310, each auxiliary boat 320 is connected to the main boat 310 through a connecting assembly 380, each connecting assembly 380 is rotatably connected to a half sleeve 350, the half sleeve 350 is connected to the end of the transverse truss 200 away from the vertical truss 100; the pump station body 360 is arranged on the floating boat and is used to discharge water in the water area. By adopting such an arrangement, the two transverse trusses 200 are respectively rotated on the two connecting assemblies 380 in a "double-arm support" manner, increasing the number of movable connection points between the transverse trusses 200 and the floating pump station assembly. This further reduces the cross-sectional dimensions of the transverse trusses 200 and improves the system stability while still meeting the requirement of driving the floating pump station assembly to smoothly and adaptably swing and lift over a wide range with large water level changes. As a result, during the installation of the large-swing floating pump station structure of this embodiment, no complex lifting equipment or professional personnel are required, and ordinary workers can quickly complete the assembly, significantly reducing the number of construction steps and shortening the construction time. At the same time, each transverse truss 200 is rotatably connected to the connecting assembly 380 via a half sleeve 350, which not only allows relative rotation between the vertical trusses 100 and the transverse trusses 200, but also allows relative rotation between the transverse trusses 200 and the floating pump station assembly for adaptive adjustment, ensuring flexible rotation at the rotation nodes and meeting the requirements for smooth posture adjustment of the floating pump station assembly under different working conditions.

[0083] It should be noted that this embodiment uses a main ship 310 and two auxiliary ships 320 to form an assembled floating ship. On the one hand, it increases the anti-tilting ability of the floating ship. On the other hand, it can be transported in separate parts, thereby facilitating transfer and movement, meeting the needs of frequent transfer mining in open-pit mines.

[0084] Specifically, the main body of the pump station 360 includes a manifold 361 and a pump body 362. The pump body 362 is installed on the auxiliary ship 320, and the manifold 361 is installed on the main ship 310. The outlet end of each pump body 362 can be independently connected to the shore outlet, or the outlet end of each pump body 362 can be connected to the manifold 361, and the manifold 361 is connected to the shore outlet. This allows the main body of the pump station 360 to be split into multiple modules according to function, and each functional module is installed on the auxiliary ship 320 and the main ship 310 respectively. This facilitates the transfer of the components and reduces the number of shore outlet pipes connected to the floating ship. More specifically, to further improve drainage efficiency, the pump body 362 can also be installed on the main ship 310.

[0085] It can be understood that the pump body 362 refers to a plurality of water suction pumps.

[0086] like Figure 7 As shown, specifically, the connecting assembly 380 includes a first portion 381, a second portion 382, ​​and a third portion 383. One end of the first portion 381 is connected to the auxiliary vessel 320, and the other end is detachably connected to the second portion 382. One end of the third portion 383 is connected to the main vessel 310, and the other end is detachably connected to the second portion 382. The half sleeve 350 is rotatably connected to the second portion 382. By separating the connecting assembly 380 into the first portion 381, the second portion 382, ​​and the third portion 383, the second portion 382 can be standardized and prefabricated in a factory. During the factory production process, advanced equipment and a strict quality control system are utilized to ensure that the dimensional accuracy and material properties of each second portion 382 meet high standards. This ensures the rotational flexibility of the rotation node formed at the connection between the half sleeve 350 and the second portion 382, ​​meeting the requirements for stable posture adjustment of the floating vessel pump station assembly under different operating conditions. The standardized design also makes the second portion 382 universal and interchangeable, thereby facilitating the replacement of damaged second portions 382.

[0087] It should be noted that, in this embodiment, the connecting assembly 380 is divided into a first part 381, a second part 382 and a third part 383. On the one hand, the floating vessel can be transported in parts for easy transfer and movement; on the other hand, the transverse truss 200 and the floating vessel pump station assembly can be disassembled and assembled, thereby facilitating the flexible transfer of this embodiment to meet the needs of sunken step mining operations in open-pit mines.

[0088] Specifically, a first flexible vibration-damping bellows 385 is detachably connected between the first part 381 and the second part 382; the first flexible vibration-damping bellows 385 can compensate for the axial and angular displacement of the connecting component 380, and act as a buffer between the main ship 310 and the auxiliary ship 320, which is conducive to improving the stability of the floating pump station component in adapting to a large range of swinging and lifting with large changes in water levels.

[0089] In a specific application, the end surfaces of the first portion 381 and the first flexible vibration-damping corrugator 385 facing each other are respectively provided with fourth connecting flanges 3811, and the two fourth connecting flanges 3811 are connected by a fifth bolt. This configuration increases the contact area between the first portion 381 and the first flexible vibration-damping corrugator 385, thereby improving the connection strength between the first portion 381 and the first flexible vibration-damping corrugator 385. The fifth bolt further detachably connects the two fourth connecting flanges 3811 into one, thereby facilitating the disassembly and assembly of the first portion 381 and the first flexible vibration-damping corrugator 385. This facilitates the prefabrication of the first portion 381 and the first flexible vibration-damping corrugator 385 in the factory and subsequent transportation to the site for assembly.

[0090] More specifically, the two fourth connecting flanges 3811 are correspondingly penetrated by a plurality of third bolt holes, and the plurality of third bolt holes are evenly spaced along the circumference of the connecting assembly 380, and the third bolt holes are used for allowing the fifth bolt to pass through; when the first part 381 and the first flexible vibration damping corrugator 385 are assembled, the fifth bolt is passed through the corresponding third bolt hole and the fifth nut is tightened.

[0091] In specific applications, the end surfaces of the second portion 382 and the first flexible vibration-damping corrugator 385 facing each other are each provided with a fifth connecting flange 3821, and the two fifth connecting flanges 3821 are connected by a sixth bolt. This arrangement increases the contact area between the second portion 382 and the first flexible vibration-damping corrugator 385, thereby improving the connection strength between the second portion 382 and the first flexible vibration-damping corrugator 385. The sixth bolt further detachably connects the two fifth connecting flanges 3821 into one, thereby facilitating the disassembly and assembly of the second portion 382 and the first flexible vibration-damping corrugator 385. This facilitates the prefabrication of the second portion 382 and the first flexible vibration-damping corrugator 385 in a factory and their subsequent transportation to the site for assembly.

[0092] More specifically, the two fifth connecting flanges 3821 are correspondingly penetrated by a plurality of fourth bolt holes, and the plurality of fourth bolt holes are evenly spaced along the circumference of the connecting assembly 380, and the fourth bolt holes are used for allowing the sixth bolt to pass through; when the second part 382 and the first flexible vibration damping corrugator 385 are assembled, the sixth bolt is passed through the corresponding fourth bolt hole and the sixth nut is tightened.

[0093] Specifically, a second flexible vibration-damping bellows 386 is detachably connected between the second part 382 and the third part 383; the second flexible vibration-damping bellows 386 can compensate for the axial and angular displacement of the connecting component 380, and act as a buffer between the main ship 310 and the auxiliary ship 320, which is conducive to improving the stability of the floating pump station component in adapting to a large range of swinging and lifting with large changes in water levels.

[0094] In a specific application, the end surfaces of the second portion 382 and the second flexible vibration-damping corrugator 386 facing each other are respectively provided with a sixth connecting flange 3822, and the two sixth connecting flanges 3822 are connected by a seventh bolt. This arrangement increases the contact area between the second portion 382 and the second flexible vibration-damping corrugator 386, thereby improving the connection strength between the second portion 382 and the second flexible vibration-damping corrugator 386. The second portion 382 and the second flexible vibration-damping corrugator 386 are detachably connected together by the seventh bolt, thereby facilitating the disassembly and assembly of the second portion 382 and the second flexible vibration-damping corrugator 386. This facilitates the prefabrication of the second portion 382 and the second flexible vibration-damping corrugator 386 in the factory and subsequent transportation to the site for assembly.

[0095] More specifically, the two sixth connecting flanges 3822 are correspondingly penetrated by a plurality of fifth bolt holes, and the plurality of fifth bolt holes are evenly spaced along the circumference of the connecting assembly 380, and the fifth bolt holes are used for the seventh bolt to pass through; when the second part 382 and the second flexible vibration damping bellows 386 are assembled, the seventh bolt is passed through the corresponding fifth bolt hole and the seventh nut is tightened.

[0096] In a specific application, the end surfaces of the third portion 383 and the second flexible vibration-damping bellows 386 facing each other are respectively provided with seventh connecting flanges 3831, and the two seventh connecting flanges 3831 are connected by an eighth bolt. This arrangement increases the contact area between the third portion 383 and the second flexible vibration-damping bellows 386, thereby improving the connection strength between the third portion 383 and the second flexible vibration-damping bellows 386. The eighth bolt further detachably connects the two seventh connecting flanges 3831 into one, thereby facilitating the assembly and disassembly of the third portion 383 and the second flexible vibration-damping bellows 386. This facilitates the prefabrication of the third portion 383 and the second flexible vibration-damping bellows 386 in the factory and their subsequent transportation to the site for assembly.

[0097] More specifically, the two seventh connecting flanges 3831 are correspondingly penetrated by a plurality of sixth bolt holes, and the plurality of sixth bolt holes are evenly spaced along the circumference of the connecting assembly 380, and the sixth bolt holes are used for the eighth bolt to pass through; when the third part 383 and the second flexible vibration damping corrugator 386 are assembled, the eighth bolt is passed through the corresponding sixth bolt hole and the eighth nut is tightened.

[0098] like Figure 7As shown, specifically, a positioning sleeve 384 is provided at each end of the second portion 382 located at the half sleeve 350. The positioning sleeve 384 is axially slidably provided on the second portion 382 and locked by a locking assembly. Through such an arrangement, on the one hand, the two positioning sleeves 384 act as a limiter for the half sleeve 350, preventing the half sleeve 350 from excessively moving axially along the second portion 382 on the second portion 382, ​​thereby ensuring that the floating vessel pump station assembly can smoothly adapt to a wide range of swinging and lifting with large changes in water levels; on the other hand, according to different limit requirements for the half sleeve 350, the locking assembly can be unlocked, and the positioning sleeve 384 can be flexibly adjusted to move axially along the second portion 382 to the desired position before being locked, thereby improving applicability.

[0099] Specifically, the positioning sleeve 384 is provided with a plurality of threaded holes spaced apart along its circumference. The locking assembly includes locking bolts 3841, the same number as the threaded holes, which match the threaded holes. When the positioning sleeve 384 needs to be locked and fixed to the second portion 382, ​​the locking bolts 3841 are simply tightened in the threaded holes until the end of the locking bolt 3841 facing away from the head presses against the outer surface of the second portion 382, ​​thereby achieving locking through friction. When the positioning sleeve 384 needs to be adjusted to move axially along the second portion 382, ​​the locking bolts 3841 are simply loosened in the threaded holes until the end of the locking bolt 3841 facing away from the head separates from the outer surface of the second portion 382, ​​resulting in a simple adjustment process.

[0100] like Figure 6 、 Figure 8 and Figure 9As shown, specifically, the transverse truss 200 includes a first transverse arm 230 and a second transverse arm 240. The first transverse arm 230 is rotatably connected to the vertical truss 100. The first transverse arm 230 and the second transverse arm 240 are each provided with a third connecting flange 250 at one end facing each other, and the two third connecting flanges 250 are connected by a fourth bolt; the second transverse arm 240 is provided with a half sleeve 350 at one end facing away from the first transverse arm 230. Because this embodiment uses two transverse trusses 200 to rotate on the two connecting assemblies 380 in a "double-arm support" manner, increasing the movable connection points between the transverse trusses 200 and the floating pump station assembly, the transverse truss 200 is split into a first transverse arm 230 and a second transverse arm 240, and the two third connecting flanges 250 are connected by a fourth bolt to connect the first transverse arm 230 and the second transverse arm 240 into one, which can not only meet the structural strength requirements, but also enable the first transverse arm 230 and the second transverse arm 240 to be standardized and prefabricated in the factory. During the factory production process, advanced equipment and a strict quality control system are used to ensure that the dimensional accuracy, material properties, etc. of the first transverse arm 230 and the second transverse arm 240 meet high standards. The standardized design makes the first transverse arm 230 and the second transverse arm 240 universal and interchangeable, reducing errors and uncertainties in on-site construction.

[0101] In a specific application, the two third connecting flanges 250 are correspondingly penetrated by a plurality of seventh bolt holes, and the plurality of seventh bolt holes are evenly spaced along the circumference of the transverse truss 200, and the seventh bolt holes are used for passing the fourth bolt; when the first transverse arm 230 and the second transverse arm 240 are assembled, the fourth bolt is passed through the corresponding seventh bolt hole and the fourth nut is tightened.

[0102] like Figure 7 As shown, specifically, a conversion rod 260 is provided between the second transverse arm 240 and the half sleeve 350, and the cross-sectional dimensions of the conversion rod 260 are smaller than the cross-sectional dimensions of the second transverse arm 240; the end surfaces of the second transverse arm 240 and the conversion rod 260 facing each other are respectively provided with an eighth connecting flange 261, and the two eighth connecting flanges 261 are connected by a ninth bolt. Through such a configuration, the eighth connecting flange 261 increases the contact area between the second transverse arm 240 and the conversion rod 260, thereby improving the connection strength between the second transverse arm 240 and the conversion rod 260; and the ninth bolt detachably connects the two eighth connecting flanges 261 into one, thereby facilitating the disassembly and assembly of the second transverse arm 240 and the conversion rod 260, and facilitating the prefabrication of the second transverse arm 240 and the conversion rod 260 in the factory and then transporting them to the site for assembly.

[0103] In a specific application, the first half sleeve 351 and the conversion rod 260 are integrally formed.

[0104] Specifically, running wheels 370 are provided at the bottom of the floating boat, and the length of the transverse truss 200 is greater than the length of the vertical truss 100, so that after all the water in the water area is drained, the floating boat pump station assembly can be lowered to abut the bottom of the open-pit mine foundation pit, so that the running wheels 370 abut against the ground for movement and transfer; it realizes amphibious use and meets the needs of frequent site movement during mining.

[0105] like Figure 9 and Figure 10 As shown, in some embodiments, a steering support 410 is provided at the top of the vertical truss 100, and two mounting seats 420 are provided on the end surface of the steering support 410 facing the transverse truss 200. The two mounting seats 420 are arranged at intervals, and each mounting seat 420 is provided with a mounting cavity 421. A mounting plate 430 is provided at one end of the transverse truss 200 facing the vertical truss 100, and support bodies 440 are provided one by one at the positions of the mounting seats 420 on the mounting plate 430. The support bodies 440 are rotatably connected to the corresponding mounting cavities 421 through a rotating shaft 450. The two support bodies 440 are rotatably connected to the two installation cavities 421 through the rotating shafts 450, so that two rotation nodes are formed between the vertical trusses 100 and the transverse trusses 200, which is conducive to improving the stability of the floating vessel pump station assembly in adapting to a large range of swinging and lifting with large changes in water levels; and ensuring the flexible rotation of the connection between the vertical trusses 100 and the transverse trusses 200, meeting the requirements of smooth posture adjustment of the floating vessel pump station assembly under different working conditions.

[0106] like Figure 11 As shown, specifically, the mounting seat 420 is penetrated by a first through hole, the first through hole is communicated with the mounting cavity 421, a screw head 451 is provided at one end of the rotating shaft 450, and a threaded portion is provided on the outer wall of the end of the rotating shaft 450 away from the screw head 451, and the threaded portion is used to threadably connect the fastening nut 460, and a second through hole is penetrated by the position of the support body 440 corresponding to the first through hole, and the second through hole and the first through hole are used for the rotating shaft 450 to pass through, and the support body 440 can rotate relative to the rotating shaft 450. Through such arrangement, when it is necessary to rotate and connect the horizontal truss 200 and the vertical truss 100 for assembly, it is only necessary to first extend the support body 440 into the installation cavity 421 so that the first through hole and the second through hole are aligned, and then the rotating shaft 450 is passed through the first through hole and the second through hole from one side of the mounting seat 420 and out from the other side of the mounting seat 420, and then the fastening nut 460 is tightened on the threaded portion until the fastening nut 460 and the screw head 451 respectively abut against the two side walls of the mounting seat 420 to complete the assembly; when it is necessary to disassemble the horizontal truss 200 and the vertical truss 100, it is only necessary to unscrew the fastening nut 460 from the threaded portion and pull out the rotating shaft 450 to remove the support body 440 from the installation cavity 421. The entire disassembly and assembly process is easy to operate, meeting the needs of frequent site movement during mining.

[0107] Specifically, the fastening nut 460 and the threaded portion are correspondingly penetrated by through holes along the radial direction of the fastening nut 460, and the through holes are used to insert the positioning cotter pin 470; when the horizontal truss 200 and the vertical truss 100 are rotated and connected and assembled, the fastening nut 460 and the threaded portion are aligned with the through holes, and the positioning cotter pin 470 is inserted into the through holes to form a physical limit line, which limits the rotation of the fastening nut 460, thereby preventing the fastening nut 460 from loosening under external influences, thereby improving the safety performance of the use of this embodiment.

[0108] Specifically, the steering support 410 is connected to the vertical truss 100 by bolts, and the mounting plate 430 is connected to the transverse truss 200 by bolts.
