DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0022] Embodiment 1:

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The nuclear magnetic tube cleaning device includes a hollow box 1, and also includes: a connecting shaft 3 rotatably connected to the hollow box 1, a nozzle 302, which is fixedly connected to the connecting shaft 3 obliquely downward, wherein a hollow cavity 301 connected to the nozzle 302 is opened on the connecting shaft 3, and a three-way joint 402 is arranged in the hollow box 1, and the output end of the three-way joint 402 is connected to the hollow cavity 301 through a rotating joint 403 arranged at the lower end of the connecting shaft 3; a booster pump 4 and a water pump 5 are both fixedly installed in the hollow box 1, wherein the output end of the booster pump 4 is fixedly connected to the input end of the three-way joint 402 through a pipe 1 401, and the output end of the water pump 5 is fixedly connected to the other input end of the three-way joint 402 through a pipe 2 501, and electromagnetic valves are arranged on the pipe 1 401 and the pipe 2 501; a clamping mechanism can be lifted and connected to the hollow box 1, and is used to clamp and fix the nuclear magnetic tube to be cleaned.

[0024] The clamping mechanism includes a U-shaped fixing frame 102 and a cylinder 2 fixedly connected to both ends of the U-shaped fixing frame 102 , and an arc-shaped plate 201 is fixedly connected to the output end of the cylinder 2 .

[0025] It also includes an electric telescopic rod 101 , which is fixedly mounted on the hollow box 1 , and a U-shaped fixing frame 102 is fixedly connected to the output end of the electric telescopic rod 101 .

[0026] An activated carbon filter is arranged in the input end of the booster pump 4 .

[0027] When in use, the nuclear magnetic tube to be cleaned is first sleeved on the connecting shaft 3 and located between the two arc plates 201, and then the two arc plates 201 are pushed by the cylinder 2 to move toward each other until the two arc plates 201 are both in contact with the outer wall of the nuclear magnetic tube, so as to clamp and fix the nuclear magnetic tube, and then the solenoid valve on the pipeline 1 401 is closed and the solenoid valve on the pipeline 2 501 is opened. At this time, the input end of the water pump 5 draws water from the external water storage tank through the hose, and sequentially transports it into the hollow cavity 301 through the pipeline 2 501 and the three-way joint 402, and finally sprays it to the inner wall of the nuclear magnetic tube through the nozzle 302, so as to clean the inner wall of the nuclear magnetic tube, and at the same time, the electric telescopic rod 101 drives the U-shaped fixing frame 102 to drive the nuclear magnetic tube to move upward, so that the nozzle 302 sprays water to the inner wall of the nuclear magnetic tube, so as to fully clean the inner wall of the nuclear magnetic tube.

[0028] After the cleaning of the inner wall of the nuclear magnetic tube is completed, the water pump 5 and the electromagnetic valve on the second pipe 501 are closed, and then the electromagnetic valve on the first pipe 401 is opened. At this time, the booster pump 4 absorbs the external gas and sequentially transmits it into the hollow cavity 301 through the first pipe 401 and the three-way joint 402, and finally sprays it out through the nozzle 302. Since the nozzle 302 is arranged obliquely downward, the water droplets remaining on the inner wall of the nuclear magnetic tube can be driven outward, thereby achieving the effect of drying the inner wall of the nuclear magnetic tube. At the same time, when the external gas passes through the input end of the booster pump 4, it contacts with the activated carbon filter (not shown in the figure). Since the activated carbon has a developed void structure and rich microporous tissue inside, these microporous tissues have a strong adsorption field. When the gas contacts the activated carbon, the strong adsorption field of the activated carbon micropores can adsorb the particles in the air into the micropores, thereby achieving the effect of filtering the gas, preventing the particles in the gas from being blown into the nuclear magnetic tube with the gas, affecting the cleaning effect of the inner wall of the nuclear magnetic tube.

[0029] Embodiment 2:

[0030] Reference Figure 1 , Figure 4 , a nuclear magnetic tube cleaning device is basically the same as Example 1, and further, a motor 6 is fixedly installed in the hollow box 1, a gear 1 601 is fixedly connected to the output end of the motor 6, and a gear 2 602 is fixedly connected to one end of the connecting shaft 3 passing through the hollow box 1, and the gear 2 602 is meshingly connected with the gear 1 601.

[0031] When the nozzle 302 moves from the inside to the outside of the nuclear magnetic tube and sprays water onto the inner wall of the nuclear magnetic tube to clean the inner wall of the nuclear magnetic tube, the motor 6 is started, and the motor 6 drives the connecting shaft 3 to rotate by meshing the gear 1 601 with the gear 2 602, so that the rotating nozzle 302 can spray water onto the inner wall of the nuclear magnetic tube without dead angles, thereby improving the cleaning effect of the inner wall of the nuclear magnetic tube.

[0032] Embodiment 3:

[0033] Reference Figure 3 The nuclear magnetic tube cleaning device is basically the same as that of Example 1, and further includes a protective pad 202, which is fixedly connected to the arc plate 201; when the nuclear magnetic tube to be cleaned is clamped and fixed, the protective pad 202 contacts the outer wall of the nuclear magnetic tube, thereby protecting the outer wall of the nuclear magnetic tube and preventing the arc plate 201 from hard contacting with the outer wall of the nuclear magnetic tube, causing scratches on the outer surface of the nuclear magnetic tube.
