Description

Technical Field

[0001] This invention belongs to the technical field of transmission line insulation tower equipment, specifically relating to a floating bridge insulation tower used in water. Background Technology

[0002] In the construction of power transmission lines crossing rivers and lakes, water crossing construction has always been a major and challenging project in power construction. Existing water crossing technologies for power transmission lines have significant limitations. For wide rivers and lakes, conventional transmission towers cannot be directly erected with fixed support structures on the water surface. Currently, the mainstream solutions in the industry are mainly divided into two types: one is to build transmission towers relying on natural islands in the water to complete the line crossing, but this method is greatly limited by geographical conditions and cannot be implemented in waters without islands, resulting in extremely poor adaptability; the other is to lay underwater cable channels. Although this can achieve power transmission over water, underwater cable laying has high construction costs, long cycles, and difficult subsequent maintenance. Furthermore, the cables are susceptible to water erosion, impact from underwater debris, and changes in water level, resulting in short service life and poor operational stability.

[0003] In addition, in the event of sudden natural disasters such as floods and water-related disasters, the existing land-based power transmission lines are easily damaged and interrupted. Disaster-stricken water areas urgently need to quickly build temporary power supply channels. However, the existing fixed transmission towers and underwater cable structures are all permanent facilities that cannot be quickly disassembled or deployed, making it difficult to meet the operational needs of rapid navigation, rapid power supply, and temporary emergency rescue in disaster emergency scenarios, which seriously restricts the efficiency of power emergency rescue and relief.

[0004] In summary, existing waterborne power transmission erection technologies suffer from poor scenario adaptability, low construction efficiency, lack of emergency response capabilities, and high operation and maintenance costs. There is an urgent need to develop a waterborne power transmission insulation support structure that can be deployed flexibly, built quickly, and adapted to various water conditions.

[0013] A cable arranging assembly is arranged on the outer side of the winch, the cable arranging assembly includes a reciprocating lead screw, both ends of the reciprocating lead screw are rotatably arranged inside the bracket through bearings, a cable arranger is screwed on the outer side of the reciprocating lead screw, the cable passes through the interior of the cable arranger, transmission gears are respectively fixed on the exterior of the reciprocating lead screw and the exterior of the central shaft of the winch, and a transmission belt is connected between the two transmission gears.

[0014] A mooring mechanism is arranged on the outer side of the pontoon bridge, the mooring mechanism includes an anchor and a buoy, and the anchor and the buoy, as well as the buoy and the pontoon bridge, are connected by anchor chains.

[0020] This invention provides a floating bridge insulation tower for underwater application, which has the following beneficial effects:

[0021] Breaking through the limitations of traditional waterway power transmission construction, it eliminates the need to build towers on islands or lay underwater cables. By using a mobile, foldable pontoon bridge to carry insulated towers / insulated scaffolding, the power transmission support structure can be built directly on the water surface.

[0025] The pontoon bridge has a folding and storage function, and its compact size after being folded makes it easy to transport and transfer. When unfolded, it has a large working area and can be used as a single unit, in multiple units, or in a continuous deployment.

Detailed Implementation

[0038] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0039] This embodiment discloses a floating bridge insulation tower for use in water, which is preferably suitable for the erection of power transmission lines in rivers with a width of more than 500m and a flow velocity of ≤2.5m / s.

[0040] Please see Figure 1-6 A floating bridge insulation tower for underwater use includes a pontoon bridge 100. The pontoon bridge 100 has its own internal power system and can be folded for storage and unfolded for operation. The pontoon bridge's self-powered system and its ability to be folded and unfolded are basic functions of existing pontoon bridge equipment and will not be elaborated here. The inner surface of the pontoon bridge 100 is provided with a bearing component 101 for placing the insulating tower 200. The bearing component 101 includes a bearing groove 1011, which is recessed into the inner surface of the pontoon bridge 100. The insulating tower 200 is installed on the upper part of the pontoon bridge 100 in an unfolded state. A support component 201 is provided at the bottom of the insulating tower 200. The support component 201 includes multiple connecting rods 2011 arranged circumferentially. The two ends of the connecting rods 2011 are fixedly connected to the bottom of the insulating tower 200. The connecting rods 2011 and the bearing groove 1011 cooperate with each other. The insulating tower 200 is connected and fixed to the bearing component 101 through the support component 201. Anchoring mechanisms 300 are provided on all four sides of the pontoon bridge 100.

[0041] The inner surface of the pontoon bridge 100 is embedded with a load-bearing component 101, which consists of multiple nested, orifice-shaped load-bearing grooves 1011. Different sized load-bearing grooves 1011 can accommodate the installation requirements of insulation towers 200 of different specifications. Multiple circumferentially symmetrically arranged connecting rods 2011 are fixed to the bottom of the insulation tower 200. The connecting rods 2011 precisely engage with the load-bearing grooves 1011, achieving the initial positioning and installation of the insulation tower 200.

[0042] The bearing groove 1011 and the connecting rod 2011 are shaped to match each other, and the support assembly 201 is provided with a positioning assembly 102 for fixing the connecting rod 2011.

[0043] The positioning component 102 includes a positioning groove 1021, the central axis of which coincides with the bearing groove 1011. Vertical screws 1022 are symmetrically fixed on both sides of the positioning groove 1021. The two vertical screws 1022 are located on both sides of the bearing groove 1011, and fastening nuts 1024 are screwed onto the outer sides of the two vertical screws 1022. A pressure plate 1023 is placed inside the positioning groove 1021. The pressure plate 1023 is provided with a through hole corresponding to the position of the vertical screw 1022 for the vertical screw 1022 to pass through.

[0044] A positioning component 102 is provided inside the bearing groove 1011. The positioning groove 1021 is coaxially arranged with the bearing groove 1011. During operation, the connecting rod 2011 is placed inside the bearing groove 1011, and the pressure plate 1023 is pressed against the upper part of the connecting rod 2011. The vertical screw 1022 passes through the through hole of the pressure plate 1023. By tightening the fastening nuts 1024 at both ends, the pressure plate 1023 is squeezed to lock and fix the connecting rod 2011, preventing the insulation tower 200 from shifting or shaking during operation and ensuring structural stability.

[0045] The bearing component 101 includes multiple sets of bearing grooves 1011 of different sizes. Each set of bearing grooves 1011 is shaped like an "U". The multiple sets of bearing grooves 1011 of different sizes are nested together for installing different models of insulation towers 200.

[0046] The anchoring mechanism 300 includes an anchor hole 301 and a cover plate 302. The cover plate 302 is detachably installed on the surface of the anchor hole 301, and an anchor assembly 303 is provided inside the anchor hole 301.

[0047] The anchor assembly 303 includes a bracket 3031 and a winch 3032. The central shaft of the winch 3032 is rotatably mounted inside the bracket 3031 via bearings. A cable 3033 is wound around the outer surface of the winch 3032, and an anchor 3034 is fixedly mounted at the end of the cable 3033. Further, the anchor 3034 is a barless anchor, preferably a Hall anchor.

[0048] A motor 3035 is fixedly installed on one side of the bracket 3031. The output end of the motor 3035 is fixedly connected to one end of the central shaft of the winch 3032. A hand crank 3036 is installed on the other side of the bracket 3031. The hand crank 3036 is fixedly connected to the other end of the central shaft of the winch 3032.

[0049] Anchoring mechanisms 300 are installed around the pontoon bridge 100. Under normal conditions, cover plates 302 seal the anchor holes 301 to prevent debris from entering. During mooring operations, cover plates 302 are removed, the anchor 3034 is manually thrown out, and the motor 3035 is started to drive the winch 3032 to rotate, causing the anchor 3034 to lock into the water. The cable 3033 is then tightened to complete the pontoon bridge positioning. In case of power failure or motor malfunction, the winch 3032 can be manually driven via a hand crank 3036. This dual-mode design ensures operational reliability. When it is necessary to retrieve the anchor 3034, a small boat is driven to the water surface directly above the anchor 3034, the angle of the anchor 3034 is adjusted, and the winch 3032 rotates in the opposite direction to retrieve the cable 3033 and the anchor 3034. The anchor hole cover plate 302 is then closed, and the pontoon bridge 100 is folded and stored, completing the overall equipment transfer and retrieval.

[0050] A cable guide assembly 304 is provided on the outside of the winch 3032. The cable guide assembly 304 includes a reciprocating screw 3041. Both ends of the reciprocating screw 3041 are rotatably mounted inside the bracket 3031 via bearings. A cable guide 3042 is screwed onto the outside of the reciprocating screw 3041. A cable 3033 passes through the inside of the cable guide 3042. Transmission gears are fixed to the outside of the reciprocating screw 3041 and the outside of the central shaft of the winch 3032. A transmission belt 3043 connects the two transmission gears.

[0051] During operation, the winch 3032 drives the reciprocating screw 3041 to rotate synchronously through the transmission gear and transmission belt 3043, which drives the cable guide 3042 to move back and forth, so as to realize the automatic straightening and laying of the cable 3033, avoid the cable from getting tangled or knotted, and extend the service life of the equipment.

[0052] In this embodiment, the entire device can be folded and stored, resulting in a compact size that facilitates vehicle and ship transport. After the equipment is transported to the shore of the work area, the folded pontoon bridge 100 is hoisted or slid onto the water surface. The built-in power system of the pontoon bridge 100 is then activated to unfold and level the pontoon bridge 100. Using the pontoon bridge 100's own power system, it is autonomously navigated to the target work location. Once the pontoon bridge 100 reaches the preset work location, the anchor hole cover plate 302 is removed, and the anchor 3034 is manually thrown to the bottom of the water. The motor 3035 is then started to drive the winch 3032 to tighten the cable 3033. The cable arrangement assembly 304 is used to neatly wind and unwind the cable 3033, completing the single-point anchoring and positioning. In the event of a power outage or malfunction of the motor 3035, the winch 3032 can be manually driven via the hand crank 3036 to complete the anchoring operation. In routine power transmission construction scenarios, fixed insulating towers are selected for assembly. Insulating tower 200 is built on the surface of pontoon bridge 100. The connecting rods 2011 arranged circumferentially at the bottom of the insulating tower 200 are precisely inserted into the bearing grooves 1011 of the corresponding specifications. Then, the pressure plate 1023 is passed through the vertical screw 1022 and pressed against the upper surface of the connecting rod 2011. The fastening nut 1024 is tightened, and the connecting rod 2011 is locked and fixed by the positioning component 102 to prevent the insulating tower 200 from shifting or loosening under force.

[0053] After the structure is installed and inspected for stability, a waterborne power transmission support structure is built based on the 200-meter insulating tower. This enables the erection of cross-water power transmission lines, emergency line repairs, and the opening of power channels. It can be used stably for a long time in waterborne power transmission construction and emergency power supply scenarios.

[0054] like Figure 7As shown, in another embodiment, to increase the stability of the pontoon bridge 100 on the water surface, at least two sets of mooring mechanisms 400 are added around the pontoon bridge 100. Anchors 401 are sunk to the bottom and fixed in place. Anchor chains 403 connect the buoys 402 to the pontoon bridge 100, further mitigating the impact of water flow and waves on the pontoon bridge 100, significantly improving the stability of operations on water. The anchor chains 403 tighten the buoys 402 to the pontoon bridge 100, and multiple sets of mooring mechanisms form multi-point limiting constraints, mitigating the impact of water flow and wave disturbances, completely locking the pontoon bridge's operating position, and preventing drifting and swaying during operations.

[0055] like Figure 8-11 As shown, in another embodiment, based on the same inventive concept, this embodiment discloses an emergency operation implementation method for the device, applicable to the scenario of rapid construction of temporary power channels on water after floods. In this embodiment, the fixed insulating tower 200 is replaced with a prefabricated insulating scaffold 500, enabling rapid assembly, disassembly, and deployment.

[0056] The insulated scaffold 500 is equipped with rollers 501 with brake pads at the bottom and foldable telescopic support rods 502 on the outside. When transporting and storing, the support rods are retracted and the brake pads are released, allowing the insulated scaffold 500 to move flexibly. When positioning and installing, the rollers 501 are pushed into the wheel grooves 1031 on the surface of the pontoon bridge 100, and the brake pads are locked, so that the rollers 501 are engaged in the anti-rotation joints 1032, restricting the rotation of the rollers. At the same time, the insulated scaffold 501 can be double-locked by the positioning component 102 to complete the bottom positioning.

[0057] The telescopic support rod 502 is deployed simultaneously, and the clamp 1042 is clamped between the support rod 502 and the fixed block 1041 of the pontoon bridge. The clamp 1042 is locked and fixed by bolts to achieve stable positioning of the support rod 502 and complete the rapid assembly of the insulated scaffold 501.

[0058] During the operation, the insulated scaffolding 500 can be assembled on the shore first, and then moved to the upper part of the pontoon bridge by the rollers 501 for fixation. Using the pontoon bridge 100's own power system, it can be quickly moved to the target water area in the disaster area. The platform is fixed by the anchoring mechanism 300 and the mooring mechanism 400. The temporary power transmission support structure can be quickly built by relying on the insulated scaffolding 500 to quickly restore the power supply in the disaster area of ​​the water area and meet the timeliness requirements of emergency rescue.

[0059] In one embodiment, two or more pontoon bridges 100 can be spliced ​​together for use. The splicing of pontoon bridges together is a basic function of existing pontoon bridge equipment, which will not be described in detail here.

[0060] In one embodiment, for ultra-wide waterways, multiple sets of pontoon bridges 100 can be continuously arranged to expand the operating range.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
