Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning device and anchoring system for intercepting objects at a cold source water intake. Background Technology

[0002] Currently, nuclear power plants generally use seawater direct current cooling as the final cold source for their units. To prevent debris and marine life from entering the cooling system with the seawater, multiple interception facilities are typically installed at the cold source intake. These facilities use nets and other structures to intercept marine life and floating objects. In existing technologies, the primary method for cleaning these nets is for maintenance personnel to approach the intake by boat and manually drag the nets onto the boat or side of the boat for cleaning. While this method can barely meet operational requirements when the number of marine organisms is small, it becomes difficult to efficiently and continuously clean the nets when large-scale invasions occur by shrimp, jellyfish, or other marine life. This is limited by the boat's operational capabilities and the limited manpower, making it challenging to effectively and continuously clean the nets. This can easily lead to partial or even complete blockage of the cold source intake, thus affecting the continuity of the unit's cold source supply. Utility Model Content

[0022] Combination Figures 1 to 9 As shown, this utility model embodiment provides a cold source water intake interception and cleaning device, applied to a cold source water intake, including a floating bridge body 10, a suction pump assembly 20, a collection assembly 30, an interception net 40, and a conveying pipe 50. The conveying pipe 50 is arranged along the length direction of the floating bridge body 10 on the side of the floating bridge body 10. The outlet end of the conveying pipe 50 is connected to the collection assembly 30, and the inlet end of the conveying pipe 50 is connected to the outlet end of the suction pump assembly 20. The interception net 40 is connected to the inlet end of the suction pump assembly 20, and the interception net 40 is located below the floating bridge body 10. The suction pump assembly 20 can suck up the intercepted objects in the interception net 40 and convey them to the collection assembly 30 through the conveying pipe 50.

[0023] In this embodiment, in the application scenario of the cold source intake area of ​​a nuclear power plant, the cold source intake interception and cleaning device is arranged in the water area in front of the cold source intake. It includes a floating bridge body 10 set on the water surface, a suction pump assembly 20 set underwater, a collection assembly 30 set on the shore or dock area, an interception net 40 set underwater in front of the cold source intake, and a conveying pipeline 50 for establishing a hydraulic conveying channel. The floating bridge body 10 floats on the water surface and serves as the installation carrier for the suction pump assembly 20 and the conveying pipeline 50, while also providing passage and maintenance personnel. The conveying pipeline 50 is set along the length of the floating bridge body 10 on its side, extending parallel to the width of the cold source intake. One end serves as the inlet end, connected to the outlet end of the suction pump assembly 20, and the other end serves as the outlet end, connected to the collection assembly 30 on the shore, thereby forming a closed conveying path from underwater to the shore. By fixing the conveying pipe 50 to the support structure on the side of the floating bridge body 10, the relative position of the conveying pipe 50 can be kept stable when the floating bridge body 10 sways slightly with the waves, thus ensuring the continuity of the suction and conveying process.

[0024] Furthermore, the interception net 40 is installed near or integrated with the existing interception facilities in front of the cold source intake, and is located in the waters below the floating bridge body 10. The interception net 40 is used to mechanically intercept marine organisms and floating debris brought by seawater flow, causing them to accumulate inside the net. The outlet or bottom of the interception net 40 is connected to the inlet of the suction pump assembly 20 via a flexible or semi-rigid pipe, allowing the intercepted material inside the interception net 40 to smoothly enter the suction pump assembly 20 during suction. The suction pump assembly 20 is preferably located in the water below the floating bridge body 10, connected to the floating bridge body 10, with its inlet connected to the interception net 40 and its outlet connected to the inlet of the delivery pipe 50. When the suction pump assembly 20 is put into operation, it draws the mixed fluid containing marine organisms and debris from inside the interception net 40. After being pressurized by the suction pump assembly 20, the fluid is sent to the delivery pipe 50, which then transports it along the side of the floating bridge body 10 towards the shore, realizing underwater suction and remote transportation of the intercepted material inside the interception net 40. The collection assembly 30 is set on the shore, dock platform, or other locations convenient for maintenance personnel to operate. Its inlet is connected to the outlet of the delivery pipe 50, and it is used to receive the mixed fluid containing marine organisms and debris transported by the delivery pipe 50. The collection assembly 30 can take the form of a collection frame, collection pool, etc. By setting up a filter or drainage structure inside the collection assembly 30, seawater is discharged from the collection assembly 30, while marine organisms and debris are retained inside the collection assembly 30, making it convenient for maintenance personnel to centrally clean, bag, and transfer the intercepted material on shore.

[0025] In one embodiment, the suction pump assembly 20 includes a suction pump body 21, a front suction pipe 22, a rear suction pipe 23, a first connector 24, and a second connector 25. One end of the front suction pipe 22 is connected to the interception net 40, and the other end of the front suction pipe 22 is connected to the suction pump body 21 through the first connector 24. One end of the rear suction pipe 23 is connected to the suction pump body 21, and the other end of the rear suction pipe 23 is connected to the delivery pipe 50 through the second connector 25.

[0026] In this embodiment, the suction pump assembly 20 includes a suction pump body 21, a pre-pump suction pipe 22, a post-pump suction pipe 23, a first connector 24, and a second connector 25. The suction pump body 21 serves as the core component providing suction power. The pre-pump suction pipe 22 introduces the mixed fluid inside the intercepting net 40 into the suction pump body 21. The post-pump suction pipe 23 transports the pressurized mixed fluid from the suction pump body 21 to the delivery pipeline 50. The first connector 24 and the second connector 25 establish reliable detachable connections between the suction pump body 21 and the pre-pump suction pipe 22, and between the post-pump suction pipe 23 and the delivery pipeline 50, respectively. One end of the pre-pump suction pipe 22 is fixedly connected to the outlet or bottom opening of the intercepting net 40. This end can be sealed to the opening of the intercepting net 40 using clamps, flanges, or threaded connections, allowing seawater and intercepted marine life and floating debris inside the intercepting net 40 to smoothly enter the pre-pump suction pipe 22 during suction. The pre-pump suction pipe 22 preferably extends from the intercepting net 40 along the water flow direction or along the bank direction to the vicinity of the suction pump body 21. The other end is connected to the inlet end of the suction pump body 21 via a first connector 24. The first connector 24 can be a quick connector or a flange connector, etc., to facilitate quick disassembly and assembly of the connection between the pre-pump suction pipe 22 and the suction pump body 21 during equipment maintenance or replacement of the suction pump body 21. Through this arrangement, the intercepted material inside the intercepting net 40 flows into the suction pump body 21 along the direction of the pre-pump suction pipe 22 during the suction process, achieving a stable transition from the interception position to the suction position.

[0027] Furthermore, one end of the post-pump suction pipe 23 is fixedly connected to the outlet end of the suction pump body 21. This connection can also be achieved by welding or bolting to the outlet flange of the suction pump body 21 to ensure the sealing and pressure-bearing capacity of the outlet when the suction pump body 21 is working. Preferably, the post-pump suction pipe 23 extends upward or towards the shore from the underwater location of the suction pump body 21, and the other end is connected to the inlet end of the delivery pipeline 50 through a second connector 25. The second connector 25 can be selected according to the structure of the delivery pipeline 50 to achieve reliable communication and convenient disassembly between the post-pump suction pipe 23 and the delivery pipeline 50. In this way, the mixed fluid containing marine organisms and debris, pressurized by the suction pump body 21, is introduced into the delivery pipeline 50 through the post-pump suction pipe 23 and transported along the direction of the delivery pipeline 50 to the collection assembly 30 on the shore for centralized treatment.

[0028] To adapt to changes in water depth and wave conditions at the nuclear power plant's cold source intake, the main body 21 of the suction pump can preferably adopt a submersible pump structure. It is connected to the floating bridge body 10 via suspension or support components, ensuring that the suction pump body 21 maintains a suitable water depth range as the floating bridge body 10 rises and falls with water level changes. The inlet suction pipe 22 and outlet suction pipe 23 can be made of flexible hoses or pipes with a certain degree of rigidity, depending on the site layout conditions, to ensure unobstructed fluid flow while also considering the overall flexibility and tensile and bending resistance of the device.

[0029] In one embodiment, a check valve 26 is provided at the connection between the pump post-suction pipe 23 and the pump body 21.

[0030] In this embodiment, the check valve 26 is installed between the outlet end of the suction pump body 21 and the inlet end of the downstream suction pipe 23. Preferably, it is a pipeline-type check valve structure adapted to the delivery pipeline 50, with its valve body axially positioned at the center line of the outlet of the suction pump body 21. The pump-side end of the check valve 26 is fixedly connected to the outlet end of the suction pump body 21 via a flange connection, threaded connection, or quick-connect structure. The pipeline-side end is fixedly connected to the end of the downstream suction pipe 23 via welding, a flange, or a quick-connect fitting, allowing the outlet channel of the suction pump body 21 to communicate with the internal space of the downstream suction pipe 23 via the check valve 26. The check valve 26 is internally equipped with a valve disc assembly that opens in the conveying direction and a return spring assembly. The valve disc opens from the suction pump body 21 towards the downstream suction pipe 23. When the suction pump body 21 is running, the mixed fluid containing marine organisms and debris, pressurized by the suction pump body 21, pushes the valve disc of the check valve 26 to open and enter the downstream suction pipe 23. When the pump stops running or there is a backflow tendency in the downstream pipeline, the valve disc closes under the action of the medium pressure difference and the return spring. Structurally, this limits the fluid flow from the suction pump body 21 to the upstream suction pipe 22 in a unidirectional direction. In application scenarios where multiple suction pump bodies 21 are arranged in parallel and connected to the conveying pipeline 50 or manifold through their respective downstream suction pipes 23, a corresponding check valve 26 is installed at the outlet end of each suction pump body 21. This forms an independent outlet section bounded by the check valve 26 in the overall pipeline layout of the device, which is beneficial for maintaining the independent operating channels of each suction pump assembly 20 and the stability of the pipeline conditions.

[0031] In one embodiment, the suction pump assembly 20 further includes a first quick connector 27, the first connector 24 is a four-way connector, and three suction pipes 22 are provided in front of the pump. One end of the three suction pipes 22 and the first quick connector 27 are respectively connected to the four ports of the four-way connector, and the other end of the first quick connector 27 is connected to the suction pump body 21.

[0032] In this embodiment, to accommodate the cleaning needs of multiple intercepting nets 40 at the cold source water inlet, the suction pump assembly 20 also includes a first quick connector 27, and the front-end pipelines are arranged in a convergence configuration: the first connector 24 is a pipeline-type four-way connector, and three suction pipes 22 are provided in front of the pump. The three suction pipes 22 extend horizontally or in the direction of water flow from the intercepting nets 40 at different positions to the vicinity of the suction pump body 21. The end of each suction pipe 22 away from the intercepting nets 40 is connected to three branch ports of the four-way connector, and the remaining port of the four-way connector is connected to one end of the first quick connector 27. The other end of the first quick connector 27 is connected to the inlet end of the suction pump body 21. Through the above arrangement, after the three suction pipes 22 converge at the four-way connector, they are connected to the suction pump body 21 via the first quick connector 27, enabling one suction pump body 21 to simultaneously establish suction channels with three intercepting nets 40 located at different positions in front of the cold source water inlet. The first quick connector 27 is preferably a quick-connect pipe structure with quick insertion and sealing functions. It is fixed to the four-way connector and the main body of the suction pump 21 by means of threads, snaps or flanges, so that when the suction pump body 21 needs to be inspected, disassembled or replaced, the pump body can be quickly separated from the three front suction pipes 22 and the four-way connector by operating the first quick connector 27. This facilitates maintenance work in the limited space under the movable floating bridge body 10. At the same time, the symmetrical or uniform connection between the four-way connector and the three front suction pipes 22 helps to balance the flow distribution of each interception net 40 during the suction process, ensuring that the suction pump assembly 20 continuously and stably suctions the intercepted objects in the multiple interception nets 40.

[0033] In one embodiment, the delivery pipe 50 includes at least one extension pipe 51, at least two manifolds 52, and a second quick connector 53. The two manifolds 52 are arranged on both sides of the floating bridge body 10 along the length direction of the floating bridge body 10. One end of the second quick connector 53 is connected to the other end of the pump suction pipe 23, and the other end of the second quick connector 53 is connected to one of the manifolds 52 through the second connector 25. And / or, one end of the second quick connector 53 is connected to the other end of the pump suction pipe 23, the other end of the second quick connector 53 is connected to one end of the extension pipe 51, the other end of the extension pipe 51 is connected to another manifold 52 through the second connector 25, and both manifolds 52 are connected to the collection assembly 30.

[0034] In this embodiment, the delivery pipeline 50 includes at least one extension pipe 51, at least two manifolds 52, and a second quick connector 53 for quickly connecting the suction pump assembly 20 to the delivery pipeline 50. The two manifolds 52 are respectively arranged on both sides of the floating bridge body 10 along its length, generally fixed at the bottom or side edge of the floating bridge body 10, and float on the water surface with the floating bridge body 10 as a whole, thus forming two main delivery channels extending along the length direction on both sides of the floating bridge body 10. The downstream end of each manifold 52 is connected to a collection assembly 30 on the shore or dock side, so as to centrally deliver the suction material from different suction pump assemblies 20 to the collection assembly 30. The suction pipe 23 of the suction pump assembly 20 located below or to the side of the floating bridge body 10 extends to the side of the floating bridge body 10 and is detachably connected to the delivery pipeline 50 via the second quick connector 53.

[0035] Specifically, in one connection method, one end of the second quick connector 53 is fixedly connected to the other end of the post-pump suction pipe 23, and the other end of the second quick connector 53 is connected to the manifold 52 on one side via the second connector 25. At this time, the mixed fluid output from the post-pump suction pipe 23 directly enters the interior of the corresponding side manifold 52 through the second quick connector 53 and the second connector 25, and is transported along the direction of the manifold 52 to the collection assembly 30 connected thereto. With this arrangement, the suction pump assembly 20 arranged near one side of the floating bridge body 10 can be connected to the manifold 52 on that side nearby, reducing the laying length of the post-pump suction pipe 23.

[0036] In another connection method, to accommodate the relative distance between the location of the partial suction pump assembly 20 and the location of the manifold 52, an extension pipe 51 is introduced into the delivery pipe 50 for transitional connection. Specifically, one end of the second quick connector 53 is also connected to the other end of the pump-fed suction pipe 23, and the other end of the second quick connector 53 is connected to one end of the extension pipe 51. The extension pipe 51 is arranged across the bottom or side of the floating bridge body 10 to the other side of the floating bridge body 10, and its other end is connected to the manifold 52 on the other side through the second connector 25, so that the suction pump assembly 20 can be connected to the manifold 52 on the opposite side. Both of the above-mentioned manifolds 52 are connected to the collection assembly 30. Therefore, regardless of whether the pump suction pipe 23 is directly connected to one side of the manifold 52 via the second quick connector 53 and the second connector 25, or connected to the other side of the manifold 52 via the second quick connector 53 and the extension pipe 51 and the second connector 25, the suction material output by the suction pump assembly 20 can be transported to the collection assembly 30 along the manifold 52, realizing the flexible arrangement and unified transportation of multiple suction pump assemblies 20 on both sides of the floating bridge body 10.

[0037] In one embodiment, the suction pump assembly 20 further includes a fixing rope 28, one end of which is fixedly connected to the delivery pipe 50 and the other end of which is fixedly connected to the suction pump body 21.

[0038] In this embodiment, to constrain the spatial position of the suction pump body 21 under movable arrangement conditions, the suction pump assembly 20 also includes a fixing rope 28. The fixing rope 28 is preferably a rope component with certain tensile strength and seawater corrosion resistance, such as a steel wire rope or synthetic fiber rope, and its length is predetermined based on the designed water depth at the cold source intake and the draft of the floating bridge body 10. Specifically, one end of the fixing rope 28 is fixedly connected to the delivery pipe 50 by means of clamps, holding pieces, or welded lifting rings, preferably at a section of the delivery pipe 50 near the bottom of the floating bridge body 10, so that the fixing rope 28 extends below or to the side of the delivery pipe 50 in spatial arrangement; the other end of the fixing rope 28 is fixedly connected to the pump body shell of the suction pump body 21 by means of lifting rings, connecting lugs, or clamping structures, thereby suspending the suction pump body 21 at a designated position below the delivery pipe 50. Through the above connection method, the fixing rope 28 forms a flexible constraint link between the delivery pipeline 50 and the suction pump body 21. When the floating bridge body 10 floats up and down with changes in water level or sways slightly under the action of wind and waves, the suction pump body 21 is kept at a predetermined suspension height range relative to the delivery pipeline 50 under the traction and limiting effect of the fixing rope 28. This ensures that the suction pump body 21 is always in the underwater working area near the cold source intake, avoiding abnormal stress on the inlet and outlet pipelines due to attitude changes. The fixing rope 28 can be set as a single rope or multiple ropes according to the site layout requirements. Multiple fixing ropes 28 can be arranged symmetrically along the circumference of the suction pump body 21 and fixedly connected to different positions of the delivery pipeline 50, so that the offset of the suction pump body 21 in the longitudinal and lateral directions is kept within the design range, thereby forming a relatively stable suspension arrangement of the suction pump assembly 20 below the floating bridge body 10.

[0039] In one embodiment, the floating bridge body 10 includes a floating bridge support 11, a floating bridge tread 12, and multiple buoyancy pipes 13. The multiple buoyancy pipes 13, the floating bridge tread 12, and the conveying pipes 50 are all arranged along the length direction of the floating bridge support 11, and the multiple buoyancy pipes 13 and the conveying pipes 50 are located at the bottom of the floating bridge support 11, while the floating bridge tread 12 is located at the top of the floating bridge support 11.

[0040] In this embodiment, the floating bridge body 10 is positioned on the water surface in front of the cold source intake, providing an installation carrier for the suction pump assembly 20 and the delivery pipeline 50, and providing a passage and operation platform for maintenance personnel. The floating bridge body 10 uses a floating bridge support 11 as its skeleton structure. The floating bridge support 11 is preferably a frame-type support extending along its length, which can be formed into a rectangular or polygonal skeleton structure by welding or bolting steel sections. Buoyancy pipes 13 and floating bridge treads 12 are respectively arranged at the bottom and top of the floating bridge support 11, thereby forming an upper passage platform and a lower buoyancy support area.

[0041] Specifically, the buoyancy pipes 13 are multiple hollow, closed float components, spaced apart at the bottom of the floating bridge support 11 along its length. Each buoyancy pipe 13 is fixedly connected to the floating bridge support 11 via support clamps, clamps, or support lugs. The buoyancy pipes 13 are arranged parallel to the length of the floating bridge body 10, ensuring a stable buoyancy distribution across the width of the cold source intake. The overall buoyancy of the floating bridge body 10 is primarily provided by the multiple buoyancy pipes 13. The delivery pipe 50 is also arranged along the length of the floating bridge support 11, positioned at the bottom of the floating bridge support 11 near the side, so that the delivery pipe 50 and the buoyancy pipes 13 are at approximately the same height. It is fixedly connected to the floating bridge support 11 via pipe clamps or support seats, thus forming a parallel arrangement of the buoyancy pipes 13 and the delivery pipe 50 at the bottom of the floating bridge support 11.

[0042] Furthermore, the floating bridge treads 12 are laid on top of the floating bridge support 11, extending along the length of the floating bridge support 11. The floating bridge treads 12 can be made of anti-corrosion wood, anti-slip steel grating, or composite materials, and are fixed to the floating bridge support 11 by bolts, pressure plates, or welded supports. The floating bridge treads 12 cover the top frame of the floating bridge support 11, so that the floating bridge body 10 forms a continuous passage surface in both length and width directions, facilitating the longitudinal movement of maintenance personnel along the floating bridge body 10 and the arrangement of related equipment during operation and maintenance. The buoyancy pipes 13 and the conveying pipes 50 are uniformly arranged in the bottom area of ​​the floating bridge support 11, and the floating bridge treads 12 are arranged in the top area of ​​the floating bridge support 11. With all components arranged along the length of the floating bridge support 11, the floating bridge body 10 has an overall elongated structure, adapting to the arrangement conditions in front of the cold source water intake and providing a continuous and stable support foundation for the laying of the conveying pipes 50.

[0043] In one embodiment, the floating bridge body 10 also includes floating bridge handrails 14 and floating bridge railings 15. The floating bridge handrails 14 are respectively disposed at both ends of the floating bridge support 11, and both ends of the floating bridge railings 15 are respectively connected to the corresponding floating bridge handrails 14.

[0044] In this embodiment, to form a safety protection structure on the floating bridge body 10 for maintenance personnel to pass through, the floating bridge body 10 also includes floating bridge handrails 14 and floating bridge railings 15 installed on the floating bridge support 11. Specifically, the floating bridge support 11 is a frame structure extending along its length, with end columns or end mounting sections corresponding to its two ends. Floating bridge handrails 14 are vertically installed at both ends of the floating bridge support 11. The floating bridge handrails 14 are preferably made of metal profiles and are fixed to the reserved connecting parts on the top or side of the floating bridge support 11, extending upwards to a certain height from the upper surface of the floating bridge tread 12, serving as protective columns and support components. Floating bridge railings 15 are respectively installed between the two side edges of the floating bridge body 10 along the length direction of the floating bridge support 11. The two ends of the floating bridge railings 15 are respectively connected to the two floating bridge handrails 14 on the corresponding sides, so that the two floating bridge handrails 14 on each side and the floating bridge railing 15 in the middle together form a lateral protective boundary extending along the length direction of the floating bridge body 10. The floating bridge railing 15 can adopt a horizontal bar or mesh structure, and is reliably connected to the floating bridge handrail 14 by welding, bolts, or clamps. Its lower end is further fixed to the edge area of ​​the floating bridge support 11 or the floating bridge tread 12 by support members, so that the floating bridge handrail 14, the floating bridge railing 15 and the floating bridge support 11 form an integrated protective frame. Through the above arrangement, the floating bridge handrail 14 forms longitudinal end posts at both ends of the floating bridge body 10, and the floating bridge railing 15 extends continuously between the end posts, so that both sides of the floating bridge body 10 form a continuous enclosure structure in the length direction, which limits the passage area of ​​personnel on the floating bridge tread 12, and facilitates the standardized guidance of personnel activity range when the movable floating bridge is deployed and maintained.

[0045] In one embodiment, the floating bridge body 10 further includes an outer tube 16 disposed at the edge of the floating bridge support 11, the outer tube 16 being used to reinforce the floating bridge support 11.

[0046] In this embodiment, to improve the overall rigidity and structural stability of the floating bridge body 10 under marine conditions, the floating bridge body 10 also includes an outer perimeter pipe 16 disposed at the edge of the floating bridge support 11. The floating bridge support 11 is a frame structure composed of a main beam extending along the length direction and several crossbeams arranged along the width direction, with its outer edge forming a rectangular or polygonal outline boundary. The outer perimeter pipe 16 is continuously arranged along this outline boundary and is disposed close to the edge of the floating bridge support 11. The outer perimeter pipe 16 is preferably made of metal tubing with a hollow cross section, such as round or square tubing, and is fixed to the outer edge of the floating bridge support 11 by welding, clamping connectors, or flange connectors, so that the outer perimeter pipe 16 substantially coincides with the outer outline of the floating bridge support 11 in the plane. The outer pipe 16 is connected to the ends of each crossbeam and main beam, and the originally relatively independent beam ends and corner nodes are connected through rigid pipes to form a closed circumferential reinforcement component around the floating bridge support 11. This enhances the overall bending and torsional resistance of the floating bridge support 11 in the length, width and diagonal directions. Thus, when the floating bridge body 10 bears the suction pump assembly 20, the conveying pipeline 50 and personnel passage load, the outer pipe 16 can play a role in structural reinforcement and boundary constraint of the floating bridge support 11, limiting its deformation under the action of waves, flow velocity and anchoring tension, and ensuring the stability of the floating bridge body 10 in the cold source water intake area.

[0047] Combination Figure 10 and Figure 11 As shown, this utility model also provides an anchoring system, including the cold source water intake interception and cleaning device as described above, and multiple anchoring groups 100 for fixing the cold source water intake interception and cleaning device. The anchoring group 100 includes an anchor rope 101, an anchor chain 102, and an anchor block 103. One end of the anchor rope 101 is connected to the cold source water intake interception and cleaning device, and the other end of the anchor rope 101 is connected to the anchor chain 102. The anchor block 103 is connected to the anchor chain 102.

[0048] In this embodiment, the anchoring system is arranged in the working water area in front of the cold source intake, including the cold source intake interception and cleaning device as described above, and multiple anchoring groups 100 for positioning and restraining the cold source intake interception and cleaning device. Each anchoring group 100 is respectively set at different positions of the floating bridge body 10. Each anchoring group 100 includes an anchor rope 101, an anchor chain 102, and an anchor block 103. One end of the anchor rope 101 is fixedly connected to the cold source intake interception and cleaning device through a mooring ring, connecting lug, or clamp structure, preferably fixed to the buoyancy tube 13 of the floating bridge body 10 or the lateral reinforcement member of the floating bridge support 11, so that the anchor rope 101 extends underwater from the edge of the floating bridge body 10; the other end of the anchor rope 101 is connected to the upper end of the anchor chain 102 through a shackle, connecting ring, or collar. Chain 102 extends downwards in a vertical or slightly inclined direction, and its lower end is fixedly connected to anchor block 103 via connectors. Anchor block 103 is placed on the underwater bedrock or seabed surface of the water area where the cold source intake is located. It is preferably a concrete block or metal block with a certain weight and bottom area. It is arranged in multiple positions around the floating bridge body 10 according to the layout range of the floating bridge body 10 in the plane, so that multiple anchoring groups 100 are symmetrically or pairedly distributed around the cold source intake interception and cleaning device. Through the above structural arrangement, anchor rope 101 forms multiple pulling paths between the cold source intake interception and cleaning device and the underwater anchor block 103. Anchor chain 102 is located between anchor rope 101 and anchor block 103 and laid close to the seabed. Anchoring group 100 forms circumferentially distributed anchoring constraints on the cold source intake interception and cleaning device in the horizontal and vertical directions, so that the cold source intake interception and cleaning device is kept within the predetermined working water area under the action of seawater flow, tidal changes and wind and waves.

[0049] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
