Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a fluorescent paint brushing detection device for monitoring oil leakage points of radiators. Background Art

[0002] Transformers are essential power equipment in the offshore wind power generation industry. Oil-immersed transformers are the most widely used type of transformers. Existing oil-immersed transformers are equipped with a plate radiator to ensure the normal operation of the transformer.

[0003] The cooling oil in the transformer needs to be refluxed into the transformer after heat exchange through the plate radiator to achieve cooling of the transformer. With the extension of service life, under the action of the corrosive medium in the surrounding environment, the coating on the surface of the transformer heat sink ages, the coating paint cracks and gradually peels off, and loses its corrosion protection effect on the metal substrate of the heat sink. The metal substrate oxidizes and loses under the action of the corrosive environment, and the rust spots expand and gradually form holes, resulting in the leakage of cooling oil, which seriously hinders the safe and stable operation of the transformer. The coating peeling phenomenon of the heat sink of the coastal wind power station transformer is more serious under the action of chloride ions. In order to detect leaks in the radiator without affecting the operation of the wind power station, it is necessary to use the fluorescent paint outline oil circuit method based on this patent to timely find the oil leakage point of the heat sink and efficiently perform maintenance operations on the transformer. However, the existing leak detection methods are mostly seen in offline shutdown detection and analysis, which cannot meet the requirements of real-time detection of oil leakage points of the heat sink without stopping the machine, affecting the maintenance and construction efficiency of the transformer.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] Reference Figure 1-Figure 5 The utility model provides a fluorescent paint brushing detection device for monitoring the oil leakage point of a radiator, comprising:

[0043] The housing 1 has an open bottom.

[0044] The batching container 2 is provided with a plurality of chambers for storing solvents and coatings respectively. The batching container 2 is arranged on one side of the top of the housing 1. The plurality of chambers are connected to a pumping mechanism through pipelines, and a first one-way valve is arranged in the pipelines.

[0045] The mixing shell 3 is arranged at the top of the inner cavity of the shell 1. The inner cavity of the mixing shell 3 is connected with the batching container 2 through a pumping mechanism. A mixing mechanism is arranged in the mixing shell 3.

[0046] The brush coating housing 4 is arranged at the bottom of the mixing housing 3.

A percolation mechanism is arranged at the top of the inner cavity of the brush coating housing 4, and a brush coating mechanism is arranged at the bottom of the inner cavity of the brush coating housing 4.

[0047] The detection shell 5 is fixedly connected to the outer wall of the outer shell 1 , and an ultraviolet lamp 6 is arranged on one side of the inner cavity of the detection shell 5 .

[0048] Different coatings and solvents are filled in several chambers in the batching container 2, and the pumping and pressing mechanism is driven to draw the coatings and solvents in the batching container 2 into the mixing shell 3. The mixing shell 3 is a square container surrounded by plastic partitions, which is connected to the batching shell through the pumping and pressing mechanism. The first one-way valve can ensure the one-way flow of materials. After the pumping and pressing mechanism draws materials, the materials in the pumping and pressing shell 7 container enter the mixing shell 3 under the action of gravity. The spiral agitator 11 is driven to achieve uniform mixing of the materials. The stirring rate and stirring time of the spiral agitator 11 are set as needed. After the mixing is completed, the uniformly mixed materials reach the brushing shell 4 through the percolation net below, and the pumping and pressing mechanism is driven to push, so that the materials can be evenly sprayed out from the spraying mechanism. After the coating is dried, the ultraviolet lamp 6 is turned on to detect leaks, wherein the second one-way valve can ensure the one-way flow of materials when the pumping and pressing mechanism is pushed.

[0049] The light source is a UV lamp or LED tube with a suitable wavelength, based on the need for light excitation frequency to produce the fluorescent effect of the fluorescent coating material. The light source is fixed at the front end of the drying tube 15 to irradiate the fluorescent coating after drying and film formation. The fluorescent coating produces fluorescence under the excitation of light of a suitable wavelength. The operator can determine the oil leakage area according to the fluorescence intensity and distribution. A tin foil reflector is pasted inside the detection housing 5 to promote light reflection. Carbon black sealant is used to seal the joints to prevent the light from the light source from leaking out.

[0062] A plurality of spray heads 14 are disposed at the bottom of the coating housing 4 and are communicated with the inner cavity of the coating housing 4 .

[0063] Further optimization plans also include:

[0065] The use of the drying tube 15 improves the film-forming efficiency of the coating and shortens the detection time of the oil leakage point of the transformer heat sink.

[0066] A digital LCD screen is provided outside the drying tube 15, which measures and displays the temperature inside the drying tube 15 in real time based on the current value of the thermistor, so as to assist in determining the ambient temperature and time required for the paint to dry. A resistance wire is provided inside the drying tube 15, and when the power is turned on, the resistance wire is energized to generate heat. When the drying tube 15 passes over the newly applied coating, it will heat the coating, thereby achieving rapid drying and film formation of the coating.
