Technical Field
[0001] The utility model relates to the technical field of pipelines, in particular to a heating mechanism for an oil suction pipe of a wind turbine generator. Background Art
[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which in turn drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of a wind rotor, a generator (including a device), a stabiliser (tail wing), a tower, a speed limiting safety mechanism and an energy storage device. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind, and it converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator rotates and generates electricity driven by the wind rotor shaft. Broadly speaking, wind energy is also solar energy, so a wind turbine can also be said to be a heat energy generator that uses the sun as a heat source and the atmosphere as a working medium. When adding lubricating oil to the inside of a wind turbine, if a lot of oil is added, a wind turbine oil suction pipe heating mechanism is needed to suck out the lubricating oil.
[0003] Prior art includes a utility model with publication number CN214888777U, which discloses an oil suction pipe heating device for a lubrication system of a wind turbine gearbox. The patent adopts a heating belt and an insulation layer, and the insulation layer is arranged on the outer layer of the heating belt; a protective cover is arranged outside the insulation layer; a temperature sensor is arranged on the heating device, and the heating device is connected to the main controller of the wind turbine; the utility model device solves the problem that most of the prior art only has a heating rod arranged in the gear cavity, but the connecting pipeline between the gear box cavity and the lubrication system is nearly 2 meters long, and the lubrication pump is in direct contact with the connecting pipeline. If the lubricating oil in the connecting pipeline cannot flow, the circulation cannot be established.
[0004] In daily work, when equipment pipelines are in use, there is a problem that when the pipelines are absorbing oil, due to the low ambient temperature, the oil inside the pipelines is easily frozen, making it difficult for the equipment to absorb oil quickly. Utility Model Content
[0005] The utility model aims to solve the defect in the prior art that the pipeline is easily affected by the environment and freezes, and proposes a heating mechanism for the oil suction pipe of a wind turbine generator.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a wind turbine oil suction pipe heating mechanism, including a placement plate, an oil absorber, a pipeline and a heating device, the upper surface of the placement plate is fixedly connected with the oil absorber, the upper surface of the oil absorber is fixedly connected with the pipeline, the heating device is arranged on the surface of the pipeline, the heating device includes a connecting frame and a tank body, the connecting frame is fixedly connected to the upper surface of the placement plate, the tank body is fixedly connected to the upper surface of the connecting frame, the lower surface of the tank body is provided with a power device, the side of the tank body is fixedly connected with a water inlet pipe, and the side of the tank body is fixedly connected with a control panel.
[0007] Furthermore, a connecting block is fixedly connected to the side of the tank body, and a water inlet pipe is fixedly connected to the side of the connecting block. By providing the water inlet pipe, the inside of the heating pipe can be connected to hot water, thereby reducing the situation where the heating pipe is directly connected to the tank body when the equipment is in use, causing wrinkles and damage at the connection between the tank body and the heating pipe.
[0008] Furthermore, one end of the water inlet pipe is fixedly connected to a heating pipe, and the heating pipe is wound around the surface of the pipe. The heating pipe can be provided to heat the pipe.
[0009] Furthermore, one end of the heating pipe away from the water inlet pipe is fixedly connected to a water outlet pipe, one end of the water outlet pipe is fixedly connected to the surface of the connecting block, and the water outlet pipe is provided to facilitate reflux of the heating pipe.
[0010] Furthermore, a limiting device is provided on the surface of the water outlet pipe, and the limiting device includes a connecting sleeve and a first limiting ring. The connecting sleeve is sleeve-connected to the surface of the water outlet pipe, and the first limiting ring is provided on the surface of the pipe. One end of the connecting sleeve is fixedly connected with a connecting rope, and the connecting rope is fixedly connected to the side of the first limiting ring. The surface of the first limiting ring is rotatably connected with a second limiting ring, and a drawing groove is provided on the side of the first limiting ring, and a clamping groove is provided on the side of the second limiting ring. A pull rod is slidably connected to the inside of the drawing groove. By providing the connecting sleeve, the heating pipe can be limited and connected, which reduces the situation where the heating pipe is prone to rebound when the equipment is in use, making it difficult for the heating pipe to fully heat the pipe.
[0011] Furthermore, one end of the pull rod is fixedly connected with a clamping rod, and the clamping rod is clamped with the inside of the clamping slot. The clamping rod is provided to facilitate the limiting of the second limiting ring and the first limiting ring.
[0012] Furthermore, one end of the pull rod is fixedly connected to a spring, and one end of the spring away from the pull rod is fixedly connected to the inner wall of the pull groove. The spring is provided to facilitate applying a restoring elastic force to the pull rod.
[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] In the utility model, when the equipment is in use, the user places the pipeline at the place where oil absorption is required to absorb the oil. When the equipment is in use, the user allows heating water to enter the tank body through the water inlet pipe, and then the control board heats the inside of the tank body. Then the power device allows the heating water inside the tank body to enter the heating pipe through the water inlet pipe to heat the pipeline. Then the heating pipe flows back into the tank body through the water outlet pipe. By setting up the heating device, the pipeline is effectively heated, which plays a role in heating the pipeline, reduces the situation that when the equipment is in use, when the pipeline is absorbing oil, the oil inside the pipeline is easily frozen due to the low ambient temperature, making it difficult for the equipment to quickly absorb oil, and improves the practicality of the equipment.
[0015] In the utility model, by providing a limiting device, when the device is in use, the user pulls the pull rod, and the pull rod moves, which drives the spring to be displaced and deformed to generate elastic force. When the pull rod moves, it drives the clamping rod to move, and the clamping rod moves out of the inside of the clamping groove, and then the second limiting ring loses its restraint, and the second limiting ring is pulled out of the surface of the first limiting ring. By providing the limiting device, the heating tube is effectively limited, which plays a role in limiting and fixing the heating tube, reduces the situation that when the device is in use, the heating tube has its own elastic force, which makes it difficult to fully lay the pipeline and heat the pipeline, thereby improving the practicability of the device.

[0025] Specifically, a connecting block 46 is fixedly connected to the side of the tank body 42 , and a water inlet pipe 47 is fixedly connected to the side of the connecting block 46 .
[0026] In this embodiment: by providing a water inlet pipe 47, the heating water can be connected to the inside of the heating tube 49, thereby reducing the situation where the heating tube 49 is directly connected to the tank body 42 when the equipment is in use, causing wrinkles and damage at the connection between the tank body 42 and the heating tube 49.
[0027] Specifically, one end of the water inlet pipe 47 is fixedly connected to the heating pipe 49 , and the heating pipe 49 is wound around the surface of the pipeline 3 . The heating pipe 49 can heat the pipeline 3 .
[0028] Specifically, one end of the heating pipe 49 away from the water inlet pipe 47 is fixedly connected to the water outlet pipe 48 , and one end of the water outlet pipe 48 is fixedly connected to the surface of the connecting block 46 . The water outlet pipe 48 is provided to facilitate the reflux of the heating pipe 49 .
[0029] In this embodiment: a limiting device 5 is provided on the surface of the water outlet pipe 48, and the limiting device 5 includes a connecting sleeve 51 and a first limiting ring 53. The connecting sleeve 51 is sleeved and connected to the surface of the water outlet pipe 48, and the first limiting ring 53 is provided on the surface of the pipeline 3. One end of the connecting sleeve 51 is fixedly connected to a connecting rope 52, and the connecting rope 52 is fixedly connected to the side of the first limiting ring 53.

[0030] In this embodiment: by providing a connecting sleeve 51, the heating tube 49 can be connected in a limited position, thereby reducing the risk of the heating tube 49 rebounding easily when the device is in use, making it difficult for the heating tube 49 to fully heat the pipeline 3.
[0031] Specifically, one end of the pull rod 57 is fixedly connected to a clamping rod 58 , and the clamping rod 58 is clamped with the inside of the clamping groove 55 . The clamping rod 58 is provided to facilitate the limiting of the second limiting ring 54 and the first limiting ring 53 .

[0033] Working principle: When the equipment is in use, the user places the pipe 3 where oil needs to be absorbed to absorb the oil. When the equipment is in use, the user allows heating water to enter the tank body 42 through the water inlet pipe 45, and then the control board 44 heats the inside of the tank body 42. Then the power device 43 allows the heating water in the tank body 42 to enter the heating pipe 49 through the water inlet pipe 47 to heat the pipe 3. Then the heating pipe 49 flows back into the tank body 42 through the water outlet pipe 48. By setting up the heating device 4, the pipe 3 is effectively heated, which plays a role in heating the pipe 3. When the equipment is in use, when the pipe 3 is absorbing oil, the oil in the pipe 3 is easily frozen due to the low ambient temperature, which makes it difficult for the equipment to quickly absorb oil, thereby improving the practicability of the equipment.
[0034] When the device is in use, the user pulls the pull rod 57, and the pull rod 57 moves, causing the spring 59 to be displaced and deformed to generate elastic force. When the pull rod 57 moves, it drives the clamping rod 58 to move, and the clamping rod 58 moves out of the inside of the clamping groove 55, and then the second limiting ring 54 loses its restraint, and the second limiting ring 54 is pulled out of the surface of the first limiting ring 53. By setting the limiting device 5, the heating tube 49 is effectively limited, which plays a role in limiting and fixing the heating tube 49, reducing the situation when the device is in use, due to the elastic force of the heating tube 49 itself, which makes it difficult for the heating tube 49 to fully lay the pipeline 3, making it difficult for the heating tube 49 to heat the pipeline 3, thereby improving the practicability of the device.
