[0034] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0035] The embodiment of the present application provides a labor-saving oil tank sampling and oil draining device, which solves the problem that the oil absorbed on the sampling rope is easily dripped onto the surface of the oil tank when the sampling rope is wound, thereby facilitating the sampling of the oil tank.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] Example:

[0038] like Figure 1-Figure 3 As shown, a labor-saving oil tank sampling and oil draining device includes a sampling rope 12, a fixing frame 20 and an oil drainer 21;

[0039] The sampling rope 12 is provided with a sampling device 13;

[0040] The fixing frame 20 is a hollow cylinder, and the fixing frame 20 is installed on the sampling hole of the oil tank;

[0041] The oil drainer 21 is mounted on the fixing frame 20 via a plurality of connecting members 22;

[0042] The oil drainer 21 comprises a hollow cylinder 211 and two funnels 212. The nozzles of the two funnels 212 are respectively located at two ends of the hollow cylinder 211 and are connected to the hollow cylinder 211. The nozzles of the funnels 212 are formed with oil drain holes 213.

[0043] The diameter of the oil-draining holes 213 is smaller than the diameter of the sampling rope 12 , and larger than the diameter of the sampling rope 12 after being squeezed by the wall of the hollow cylinder 211 .

[0044] When in use, the sampling rope 12 passes through the oil drain hole 213 and the hollow cylinder 211, and then, the end of the sampling rope 12 with the sampler 13 is placed inside the oil tank through the oil tank sampling hole, and the fixing frame 20 is set on the sampling hole. After the sampler 13 completes the oil extraction, the sampling rope 12 is pulled upward, and the sampling rope 12 slides in the oil drain hole 213 in the oil drainer 21. At this time, due to the pore size of the oil drain hole 213 They are all smaller than the diameter of the sampling rope 12, and larger than the diameter of the sampling rope 12 after being squeezed by the wall of the hollow cylinder 211. Therefore, the oil draining hole 213 squeezes the oil on the sampling rope 12 to drain the oil from the sampling rope 12, which solves the problem that the oil absorbed by the sampling rope 12 is easy to drip onto the surface of the oil tank when the sampling rope 12 is rolled up, causing waste of oil and environmental pollution, and further leading to inconvenience in oil sampling.

[0045] like Figure 1-Figure 2 As shown, the sampling rope 12 is provided with a sealing ring 121.

[0046] By providing the sealing ring 121 , the sealing ring 121 has elasticity and can better drain the oil from the sampling rope 12 after passing through the oil drain hole 213 .

[0047] like Figure 4-Figure 7 As shown, a gap 214 is provided on the oil drainer 21 , the gap 214 is connected to the oil drain hole 213 , and the width of the gap 214 is smaller than the diameter of the sampling rope 12 .

[0048] By setting the gap 214, the gap 214 shared by the hollow cylinder 211 and the two funnels 212 can allow the sampling rope 12 to move in and out when force is applied, and can facilitate the sampling rope 12 with the sampler 13 to be detached from the oil drainer 21, so as to facilitate the sampling operation of the sampler 13 and the sampling rope 12. When in use, when the sampling rope 12 passes through the gap 214, the sealing ring 121 on the sampling rope 12 is located below the oil drainer 21. As the sampling rope 12 drives the sampler 13 to rise after the sampling is completed, the sealing ring 121 abuts against the bottom of the oil drainer 21. After the abutment, the sampling rope 12 continues to rise along the oil draining hole 213. At this time, the sealing ring 121 squeezes the oil absorbed by the sampling rope 12. Since the sealing ring 121 is elastic, the sealing ring 121 can achieve a better oil draining effect.

[0049] It should be noted that, in order to achieve a better oil drainage effect, the inner diameter of the sealing ring 121 is smaller than the diameter of the sampling rope after it absorbs oil and expands.

[0050] like Figure 1As shown, the sampling and oil drainage device also includes an oil drainage box 10, on which a wire rack 11 is installed, and a roller is rotatably connected to the wire rack 11, and one end of the sampling rope 12 away from the sampler 13 is wound around the roller, and a handle 111 is installed on the wire rack 11.

[0051] By setting up a wire rack 11 and utilizing the wire rack 11 to realize the retraction and extension of the sampling rope 12, the purpose of saving effort can be achieved, the labor intensity of the operator is reduced, and the sampling efficiency is improved. The handle 111 drives the roller to rotate and pull the sampler 13 to be lowered and lifted, avoiding damage to the hands caused by direct contact and friction with the rope.

[0052] The oil drain box 10 is provided with a sleeve 14 for placing the sampler 13 .

[0053] Specifically, the sleeve 14 is detachably connected to the oil drain box 10, for example, by a threaded connection.

[0054] The oil drain box 10 is provided with an oil storage tank 101 , and the oil storage tank 101 is used to store the oil extracted by the sampler 13 .

[0055] like Figure 8 As shown, the fixing frame 20 is fixed to the sampling hole by bolts 23 to ensure the stability between the fixing frame 20 and the oil tank, thereby facilitating the sampling of the sampler 13.

[0056] During operation, the fixing frame 20 is fixed to the sampling hole by bolts 23, and then the sampling device 13 is placed in the oil tank through the gap formed between the connecting piece 22 and the fixing frame 20. At this time, the sampling device 13 is immersed in the grain and oil in the oil tank, and the sampling rope 12 of the fixed sampling device 13 is inserted into the oil drain hole 213 in the oil drainer 21 through the gap 214. It should be noted that when the sampling rope 12 is inserted into the oil drain hole 213 through the gap 214, the sealing ring 121 on the sampling rope 12 is located below the oil drainer 21, and the distance between the sealing ring 121 and the bottom of the oil drainer 21 does not exceed the distance between the oil drainer 21 and the bottom of the oil drainer 21. The distance from the oil surface in the oil tank is achieved by rotating the roller on the wire rack 11 to realize the winding of the sampling rope 12, and then the sampler 13 is pulled upward. At this time, the oil draining hole 213 and the sealing ring 121 squeeze the oil on the surface of the sampling rope 12 to achieve the oil draining operation. As the sampling rope 12 is pulled, the sampler 13 contacts the oil drainer 21. At this time, the sampling rope 12 is taken out from the side of the oil drainer 21 through the gap 214. After that, the oil in the sampler 13 is placed in the oil storage tank 101. The last operation is repeated many times until the sampling amount reaches the requirement, and the sampler 13 is placed in the sleeve 14 for storage.

[0057] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0058] 1. By providing the oil drainer 21, the problem that the oil absorbed by the sampling rope 12 is easily dripped onto the surface of the oil tank when the sampling rope 12 is rolled up, causing waste of oil and environmental pollution, and further causing inconvenience in oil sampling is solved.

[0059] 2. By providing the sealing ring 121 , the sealing ring 121 is elastic and can better drain the oil from the sampling rope 12 .

[0060] 3. By setting the gap 214, the gap 214 shared by the hollow cylinder 211 and the two funnels 212 can allow the sampling rope 12 to move in and out when force is applied, and can facilitate the sampling rope 12 with the sampler 13 to be detached from the oil drainer 21, thereby facilitating the sampling operation of the sampler 13 and the sampling rope 12.
