Abstract
Description
Technical Field
[0001] The invention relates to the technical field of power plant detection, and in particular to an oil sampler for power plant detection. Background Art
[0002] In order to ensure the stable operation of power plants, professional technicians are usually required to go to the site to sample and analyze the equipment and the oil used in the equipment. In order to ensure the safety of sampling and the representativeness of the samples, special sampling equipment is required for sampling. At present, there is no suitable sampler for daily sampling, and the oil is usually directly collected from the oil tank opening by opening the oil tank cap. Therefore, there are the following defects: (1) The sample is easily contaminated by the surrounding environment and the rust of the oil tank valve, resulting in the test results having no reference value; (2) When the oil tank cap fails, the oil used in the equipment will be sprayed, and the interlock will cause the equipment to stop and cause the risk of fire; (3) Some lubricating oil samplers are difficult to control the amount of lubricating oil sample taken out. If the amount of lubricating oil sample taken out is too much, it will cause a waste of resources. If the amount taken out is small, secondary sampling is required, which wastes sampling time. Summary of the invention
[0003] The present invention proposes an oil sampler for power plant testing, which solves the problems of (1) the sample is easily contaminated by the surrounding environment and rust on the oil tank valve, resulting in the test result being of no reference value; (2) when the oil tank cover fails, the equipment oil is sprayed, and the interlock causes the equipment to stop and cause a fire risk; (3) some lubricating oil samplers are difficult to control the amount of lubricating oil sample taken out. If the amount of lubricating oil sample taken out is too much, it will cause a waste of resources. If the amount taken out is small, secondary sampling is required, which wastes sampling time.
[0004] The technical solution adopted by the present invention is: an oil sample sampler for power plant detection, including an oil tank and a sampling bottle, the top of the oil tank is provided with an oil tank port, the top of the sampling bottle is provided with a pump body, the suction end of the pump body is provided with an oil extraction pipe, the outer side of the oil extraction pipe is provided with a bottle cap, and the discharge end of the pump body is provided with an oil delivery pipe connected to the sampling bottle.
[0005] As a further improvement of the present invention, a scale bar is provided on the surface of the sampling bottle to facilitate real-time viewing of the amount of oil taken.
[0006] As a further improvement of the present invention, a counterweight is fixedly sleeved on one end of the oil extraction pipe, so as to facilitate the oil extraction pipe to penetrate into the bottom of the oil tank for sampling.
[0007] As a further improvement of the present invention, the counterweight block is composed of a plurality of counterweight blocks which are sleeved on the oil extraction pipe in an overlapping manner.
[0008] As a further improvement of the present invention, the weights of the counterweight blocks are all the same.
[0009] As a further improvement of the present invention, the bottle cap is rotatably connected to the oil extraction pipe, and the bottle cap is threadedly connected to the oil tank port, which improves the stability of the oil extraction process and avoids the lubricating oil circuit in the natural environment.
[0010] Beneficial effects of the present invention:
[0011] 1. The present invention utilizes the threaded connection between the bottle cap and the oil tank port during the oil extraction process, thereby improving the stability of the oil extraction process, and the operation safety of the on-site sampling personnel is high, which can ensure the safe and stable operation of the unit.
[0012] 2. When sampling the oil tank, the oil sampling pipe is extended into the oil tank through the counterweight block, which avoids the entire sampling device from bringing in a large amount of impurities, reduces the contamination of the lubricating oil in the oil tank by the sampler, and ensures the accuracy of lubricating oil detection.
[0013] 3. The sampling bottle is made of transparent material and has a scale bar on the surface, so you can check the amount of oil taken out in real time, saving the time of multiple sampling due to insufficient sampling volume at one time, and avoiding waste of resources caused by excessive sampling.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and implementation methods. It should be understood that the implementation methods described herein are only used to explain this application and are not used to limit this application.
[0018] Embodiment 1:
[0019] The present invention provides Figure 1 , Figure 2 An oil sample sampler for power plant testing is shown, comprising an oil tank 1 and a sampling bottle 2, wherein the top of the oil tank 1 is provided with an oil tank port 3, the top of the sampling bottle 2 is provided with a pump body 4, the suction end of the pump body 4 is provided with an oil extraction pipe 5, the outer side of the oil extraction pipe 5 is provided with a bottle cap 6, and the discharge end of the pump body 4 is provided with an oil delivery pipe 7 connected to the sampling bottle 2.
[0020] like Figure 1 and Figure 2 As shown, the sampling bottle 2 in the first embodiment is provided with a scale bar 8 on its surface. Since the sampling bottle 2 is made of transparent material, the amount of oil taken out can be checked in real time, which saves the time of multiple sampling due to insufficient sampling volume at one time and avoids waste of resources caused by excessive sampling.
[0021] like Figure 1 As shown, in the first embodiment, a counterweight block 9 is fixedly sleeved at one end of the oil extraction pipe 5. The counterweight block 9 is used to extend the oil extraction pipe 5 into the oil tank, thereby preventing the entire sampling device from bringing in a large amount of impurities, reducing the contamination of the lubricating oil in the oil tank 1 by the sampler, and ensuring the accuracy of the lubricating oil detection. The counterweight block 9 is sleeved on the oil extraction pipe 5 in an overlapping manner using a plurality of counterweight blocks. When performing the oil extraction operation, the number of counterweight blocks can be added in sequence as needed, so that the oil extraction port of the oil extraction pipe 5 is pressed to different oil extraction heights, thereby obtaining oil samples at different positions. For example, when it is necessary to obtain the oil in the top layer, no counterweight block is added; when it is necessary to drive the oil in the middle and upper layers, a counterweight block is added and pressed below a certain liquid level, so that the oil at the desired oil layer depth can be driven. For example, if other impurities are involved in the oil, it is difficult to accurately measure the oil product when the oil is extracted at a fixed height. As a further improvement of the present invention, the weights of the counterweight blocks are all the same, and the position of the oil inlet can be reasonably and quickly adjusted according to the number of counterweight blocks added.
[0022] In the first embodiment, the bottle cap 6 is rotatably connected to the oil extraction pipe 5, and the bottle cap 6 is threadedly connected to the oil tank port 3. The threaded connection between the bottle cap 6 and the oil tank port 3 makes the oil extraction process more stable and avoids the influence of shaking of the sampling device on the oil extraction.
[0023] Real-time example 2:
[0024] In summary, if Figure 1 and Figure 2 As shown, during use, when it is necessary to take oil from the tank, first open the tank cap, then insert the oil taking pipe 5 into the tank 1, and make the bottom end of the oil taking pipe 5 penetrate into the bottom of the tank 1 through the counterweight 9, so as to avoid the entire sampling device from bringing in a large amount of impurities, and at the same time ensure the accuracy of lubricating oil detection, and then control the bottle cap 6 to rotate so that it is connected to the tank port 3, so as to reduce the contamination of the lubricating oil in the tank 1 by the sampler, make the oil taking process more stable, and avoid the influence of the shaking of the sampling device on the oil taking, and control the pump body 4 to start, so as to discharge the oil sample in the tank 1 into the sampling bottle 2 through the oil taking pipe 5 using the oil pipe 7, and the oil taking amount can be checked in real time through the scale bar 8, which saves the time of multiple sampling due to insufficient sampling amount at one time, and also avoids the waste of resources caused by multiple sampling.
[0025] Embodiment three:
[0026] In summary, if Figure 1 and Figure 2 As shown, during use, when sampling is completed, the bottle cap 6 is controlled to rotate in the opposite direction to separate the bottle cap 6 from the tank port 3, the oil extraction pipe 5 is taken out from the tank 1, and then the tank cap is closed to seal the tank 1 to prevent the lubricating oil from spraying and leaking, and finally the lubricating oil in the sampling bottle 1 is tested.
[0027] The above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the implementation modes of the present invention.
