Description

Technical Field

[0001] This utility model relates to the technical field of installation fixtures for high-level water tanks in towers, specifically a device for installing high-level water tanks inside towers. Background Technology

[0002] The nacelle (top of the tower) of a wind turbine houses core equipment such as generators, converters, and gearboxes. Its cooling and fire suppression systems have rigid requirements for water pressure. Generators, converters, and other equipment require continuous water cooling (or water-air cooling) during operation, and components such as heat exchangers and circulation pipes require stable water pressure to achieve efficient heat exchange. According to fluid mechanics principles, approximately 0.1 MPa of water pressure is generated for every 10-meter rise in water level. The height at the top of the tower (80-200 meters) naturally generates 0.8-2 MPa of water pressure, eliminating the need for an additional booster pump and reducing the risk of pump failure due to high-altitude vibration and low-temperature environments.

[0003] In existing technologies, the high-level water tank, installation materials, connecting hoses, and construction tools are usually hoisted to the second-floor tower platform using hoisting equipment. The water tank is then placed near the ladder. For example, utility model CN210660455U discloses an open cooling system at the bottom of an offshore wind turbine tower (hereinafter referred to as Prior Art 1), which includes a water-cooled circulation system and a pressure stabilizing device. The water-cooled circulation system includes a pump station, an external radiator, several internal power consumption components, and internal radiators and piping. The pump station includes a filter, a circulating water pump, a pressure relief valve, and a three-way valve. The external radiator is located outside the tower and connected to the inside of the tower via water pipes. All other components are installed inside the tower. The pressure stabilizing device consists of a high-level water tank, a breather valve, a salt spray filter, and a level gauge for monitoring the water level. Integration; the circulating water pump provides circulation power for the open water cooling system; after the coolant flows out from the bottom pump station, it flows through the pump station's three-way valve. When the pump station's three-way valve is fully closed, the coolant does not pass through the external radiator and flows directly into the tower through the pipeline. It then flows into each power consumption component inside the tower through a branching process. For power consumption components with complex internal coolant circulation structures, the output coolant flows into the high-level water tank for venting and stabilizing in the pressure stabilizing device. The coolant flowing out of the high-level water tank then enters the radiator inside the tower. For power consumption components with simple internal coolant circulation structures, the output coolant directly enters the radiator inside the tower. The confluence coolant in the radiator inside the tower returns to the circulating water pump; when the pump station's three-way valve is fully open, the coolant flows into the external radiator. The coolant cooled by the external radiator returns to the tower and flows into each power consumption component inside the tower through a branching process.

[0004] However, the existing technology for hoisting high-level water tanks for wind turbine generators involves high-altitude precision operations. Multiple factors can cause deviations between the hoisting points and the fixing holes on the tower platform, preventing the bolts from securing the high-level water tank to the tower platform. This necessitates a second hoisting at high altitude, which is not only time-consuming but also increases the risk of swaying due to prolonged suspension. Furthermore, the tower platform has a limited area, restricting subsequent repositioning operations and making it inconvenient to manually reposition the high-level water tank already placed on the tower platform. Utility Model Content

[0005] The purpose of this utility model is to provide an installation device for a high-level water tank inside a tower, which can solve the problems of insufficient hoisting alignment accuracy and difficulty in secondary adjustment in a narrow space when there is a deviation between the hoisting point of the high-level water tank and the fixing hole set on the tower platform in the actual use.

[0009] The base is detachably connected to the tower platform, and the first slide groove and the second slide groove are arranged perpendicularly.

[0010] Preferably, the receiving seat is provided with a limiting groove.

[0011] Preferably, the limiting groove is a stepped groove.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] See Figures 1-3 This embodiment discloses an auxiliary tooling for installing a high-level water tank 115 on a tower platform located at a high position in the tower. Specifically, it is a high-level water tank installation device inside the tower, including a buffer mechanism 101, a slide rail 102, and a base 103 for installation on the tower platform. The slide rail 102 is connected to the base 103 through the buffer mechanism 101.

[0034] The slide rail 102 is provided with a first slide groove 104 and a second slide groove 105. The telescopic end of the buffer mechanism 101 is connected to a guide block 112. The telescopic end of the buffer mechanism 101 is slidably installed in the first slide groove 104 through the guide block 112. A receiving seat 106 is slidably installed in the second slide groove 105.

[0035] The base 103 is detachably connected to the tower platform, and the first slide groove 104 and the second slide groove 105 are arranged perpendicularly.

[0036] In this embodiment, the tower platform is provided with several fixing holes, and the base 103 is detachably connected to the fixing holes. When installing the high-level water tank 115, the base 103 is first fixed to the tower platform by a detachable connection method, such as by bolts. Then, the high-level water tank 115 is hoisted and placed on the support 106 using conventional hoisting equipment such as a hoisting arm or a gantry hoisting mechanism. If there is a deviation between the hoisting point and the fixing hole of the tower platform along the direction of the first slide groove 104, the support 106 is pushed to slide within the first slide groove 104, which can adjust the position of the slide rail 102 and the high-level water tank 115 on the support 106 along the direction of the first slide groove 104. If there is a deviation between the hoisting point and the fixing hole of the tower platform along the direction of the second slide groove 105, the support 106 is pushed to slide within the second slide groove 105, which can adjust the position of the high-level water tank 115 along the direction of the second slide groove 105. By coordinating the adjustment of the first slide 104 and the second slide 105 in two directions, the deviation between the lifting point and the fixing hole can be fully adapted, eliminating the need for secondary lifting at high altitude, greatly reducing operational risks and saving operation time. The buffer mechanism 101 can effectively buffer the water tank 115 when it is placed on the support seat 106, reducing the damage to the water tank 115 and the tower platform caused by the lifting impact, and further improving the safety of the installation operation.

[0037] In some embodiments, a limiting groove 107 is provided on the receiving seat 106. In actual use, when adjusting the position of the high-level water tank 115 through the first sliding groove 104 and the second sliding groove 105, it is necessary to push the high-level water tank 115 to adjust its position; by providing the limiting groove 107, the high-level water tank 115 can be stably restricted to a preset position on the receiving seat 106 by adapting and engaging with the bottom structure of the high-level water tank 115, ensuring that the high-level water tank 115 and the receiving seat 106 move synchronously during the adjustment process.

[0038] In some embodiments, the limiting groove 107 is a stepped groove 108. The tower of a wind turbine generator may be equipped with elevated water tanks 115 of different sizes or models depending on the generator's power and operational requirements. The bottom structure dimensions of elevated water tanks 115 vary depending on their size. The stepped groove 108, by providing multiple steps of different depths and widths, can accommodate the bottom structures of elevated water tanks 115 of various sizes, improving the versatility and applicability of the installation device and reducing equipment procurement and maintenance costs.

[0039] In some embodiments, the buffer mechanism 101 includes a fixed cylinder 109 and a movable part 110. The fixed cylinder 109 is mounted on the base 103, and the movable part 110 is slidably connected to the fixed cylinder 109. An elastic element 111 is connected inside the fixed cylinder 109, and one end of the elastic element 111 away from the inside of the fixed cylinder 109 is connected to the movable part 110. A guide block 112 is disposed on the movable part 110, and the movable part 110 is slidably connected to the first sliding groove 104 through the guide block 112. In this embodiment, the fixed cylinder 109 is fixedly connected to the base 103, and the elastic element 111 is a spring mechanism. When the high-level water tank 115 is hoisted and placed on the receiving seat 106, a certain impact force will be generated. Under the action of the impact force, the movable part 110 will slide into the fixed cylinder 109, compressing the elastic element 111 inside the fixed cylinder 109. The elastic element 111 absorbs the impact force through its own elastic deformation, converting the instantaneous impact force into elastic potential energy. This significantly reduces the impact of the high-level water tank 115 on the base 103 and the tower platform, preventing the high-level water tank 115 from being damaged by the impact. It also reduces the impact on the tower platform structure, protecting the safety and stability of the tower platform.

[0040] In some embodiments, a limiting rod 113 is connected to the slide rail 102. By setting the limiting rod 113, the maximum sliding distance of the moving part 110 can be directly limited: when the high-level water tank 115 is hoisted to the receiving seat 106, the moving part 110 compresses the spring under the weight of the water tank until the limiting rod 113 contacts the base 103 and stops sliding. At this time, only a small gap is left between the bottom of the water tank and the platform surface to facilitate the adjustment of the high-level water tank 115, preventing the elastic element 111 from being over-compressed under the weight of high-level water tanks 115 of different sizes and dimensions, which would cause the water tank to exert excessive pressure on the platform and damage the platform structure; and by setting the limiting rod 113, the spring can also be prevented from being over-compressed, which maintains stable contact between the water tank and the platform and prevents the spring from failing due to overload.

[0041] In some embodiments, the receiving seat 106 is provided with a placement groove, in which a counterweight is detachably installed. When the bottom of the elevated water tank 115 of different sizes and dimensions is difficult to move to a position with a small gap between it and the platform surface to facilitate the adjustment of the elevated water tank 115 due to its small weight, the counterweight can be placed in the placement groove to increase the weight. This avoids a large gap between the elevated water tank 115 and the tower platform due to insufficient spring compression, which would make it inconvenient to install the elevated water tank 115.

[0042] In some embodiments, the limiting rod 113 is threadedly connected to the slide rail 102. By rotating the limiting rod 113, it can be extended or retracted along the thread direction, thereby precisely adjusting its effective length. In the installation requirements of the elevated water tank 115, it is necessary to ensure that the water tank, after being placed on the support 106, just contacts the platform. A small gap is left between the elevated water tank 115 and the tower platform to facilitate the adjustment of the elevated water tank 115. The limiting rod 113, threadedly connected to the slide rail 102, can be adjusted according to the actual installation situation: if the gap between the water tank and the platform is too large, the limiting rod 113 can be appropriately shortened to allow the spring to compress further, causing the moving part 110 to drive the slide rail 102 and the support 106 to move downwards; if the water tank presses the platform too tightly, the limiting rod 113 can be extended to limit excessive spring compression, avoid excessive force on the platform, and ensure that only a small gap is left between the elevated water tank 115 and the tower platform to facilitate the adjustment of the elevated water tank 115. Furthermore, once the elevated water tank 115 has moved to the position corresponding to the expected fixing hole, the operator can shorten the effective length of the limiting rod 113 by rotating it: the limiting rod 113 retracts inward along the threaded hole of the slide rail 102, and the receiving seat 106 and the elevated water tank 115 above it descend synchronously. This continues until the bottom end of the elevated water tank 115 contacts the surface of the tower platform, and the weight of the water tank is transferred to the platform through the bottom end, facilitating fixation by the operator. In this embodiment, the limiting rod 113 can be rotated manually or using a conventional electric wrench, depending on the actual needs.

[0043] In some embodiments, seepage holes are provided in the first groove 104 and the second groove 105, and a filling chamber communicating with the seepage holes is provided in the slide rail 102. Long-term sliding within the first groove 104 and the second groove 105 can easily lead to component wear due to friction, affecting the cushioning effect and service life. The filling chamber stores lubricant such as lubricating oil or grease, while the seepage holes allow the lubricant in the filling chamber to slowly and evenly permeate to the contact surfaces between the first groove 104 and the second groove 105 and the slide rail and the moving part 110. This continuously provides lubrication to the sliding parts, reducing the wear rate and noise during the sliding process.

[0044] In some embodiments, a pad is rotatably connected to the bottom end of the limiting rod 113. The pad is rotatably connected to the limiting rod 113 via a bearing. By providing the pad, wear caused by friction between the limiting rod 113 and the base 103 can be avoided when the limiting rod 113 contacts the base 103 and needs to rotate.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
