The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0033] Now, the present utility model will be further described in combination with the attached drawings and the detailed implementation manner. Please refer to Figure 1 - Figure 9 As shown, a land-based fluid cryogenic loading and unloading arm according to an embodiment of the present utility model includes an electric slide rail 1. A base 2 is provided at the moving end of the electric slide rail 1. A first adjustment component 3 is provided at one end of the base 2 for adjusting the height of the loading and unloading arm. A second adjustment component 4 is provided on the first adjustment component 3 for adjusting the incoming fluid. A controller 11 is provided on one side of the base 2. Four electric push rods 9 are provided at one end of the base 2. The moving end of the electric push rod 9 extends from one end of the base 2 to the other end of the base 2 and is provided with a fixed block 10.

[0034] Specifically, when using the cryogenic loading and unloading arm, the cryogenic loading and unloading arm can be moved left and right through the electric slide rail 1. The fixed stability and fixing effect of the cryogenic loading and unloading arm can be ensured through the electric push rod 9 and the fixed block 10.

[0035] As Figure 1 - Figure 9As shown in the figure, the first adjustment component 3 includes a column 301. The column 301 is arranged at one end of the base 2. A first motor 302 is arranged inside the column 301. The rotating shaft of the first motor 302 is connected to a threaded rod 303 through a coupling. A moving rod 304 is threadedly connected to the threaded rod 303. A limiting port 5 is opened on one side of the column 301. A limiting protrusion 305 is arranged on the moving rod 304. The limiting protrusion 305 is arranged in the limiting port 5, and the limiting protrusion 305 is adapted to the limiting port 5. A liquid storage tank 306 is arranged on the column 301. Six delivery pipes 307 are connected to the liquid storage tank 306. One end of the delivery pipe 307 extends from the outside of the column 301 to the inside of the column 301. A diffusion cotton 308 is arranged inside the column 301 where the delivery pipe 307 is located. A delivery cotton thread 309 is arranged inside the delivery pipe 307.

[0036] Specifically, when it is necessary to adjust the height of the cryogenic loading arm, the first motor 302 is started through the controller 11. Then, the rotating shaft of the first motor 302 drives the threaded rod 303 to rotate. Immediately, the threaded rod 303 drives the moving rod 304 and the limiting protrusion 305 to move in the limiting port 5. During the movement, the moving rod 304 comes into contact with the diffusion cotton 308. Then, the lubricating solution in the liquid storage tank 306 is delivered to the delivery cotton thread 309 through the delivery cotton thread 309, so as to avoid the problems that the moving rod 304 is inconvenient to move or there is resistance during the moving adjustment.

[0037] As Figure 1 - Figure 9 As shown in the figure, the second adjustment component 4 includes an inner arm 401. The inner arm 401 is arranged on the moving rod 304 through a fixing frame. An interface flange 402 is arranged at one end of the inner arm 401. An outer arm 403 is connected to the inner arm 401. A balancer 404 is arranged on the outer arm 403 through a first fixing plate, and the moving end of the balancer 404 is arranged at the junction of the inner arm 401 and the outer arm 403. A vertical pipe 405 is connected to one end of the outer arm 403. A connection joint 6 is arranged at one end of the vertical pipe 405. A shell 406 is arranged on the vertical pipe 405. A rotating port 7 and an ultrasonic flowmeter 413 are opened on one side of the shell 406. The principle of the ultrasonic flowmeter 413 is the same as that of the external clamp ultrasonic flowmeter with the model TUF-2000SW. The ultrasonic flowmeter 413 is composed of a detection head and a detection main body. The detection main body is arranged on the vertical pipe 405 through a third fixing plate. The detection head is fixed on the vertical pipe 405 through a hoop, and the detection head is connected to the detection main body through a wire.

[0038] On the vertical pipe 405, a second motor 407 is provided through the second fixing plate. The rotating shaft of the second motor 407 is installed with a driving gear 408. Part of the driving gear 408 is arranged in the rotating port 7. A driven gear 409 is meshed with the driving gear 408. A regulating plate 410 with a triangular-like structure is fixedly arranged on the driven gear 409. Adjusting grooves 8 with a hexagonal structure are formed at both ends of the regulating plate 410. A moving plate 411 is connected in the adjusting grooves 8. A convex block with a rectangular structure is arranged at one end of the moving plate 411, and the convex block is adapted to the adjusting groove 8. A column with a cylindrical structure is arranged at the other end of the moving plate 411. One end of the moving plate 411 is connected with an auxiliary plate 412. Six limiting grooves are formed on the auxiliary plate 412 during the meeting, and the column slides in the limiting grooves. The auxiliary plate 412 is arranged on the inner wall of the housing 406. During actual use, sealing structures are arranged on both the housing 406 and the auxiliary plate 412 to avoid leakage problems when the fluid passes through.

[0039] Specifically, when the fluid flow rate detected by the ultrasonic flowmeter 413 is low or small, the second motor 407 is started through the controller. Then, the rotating shaft of the second motor 407 drives the driving gear 408 to rotate. Immediately, the driving gear 408 and the driven gear 409 cause the regulating plate 410 to rotate. When the regulating plate 410 rotates, the moving plate 411 will move along with the limiting grooves and the adjusting grooves 8, so as to realize the adjustment of the fluid flow rate for multiple times, and thus the flow rate can be adjusted according to the fluid velocity, thereby ensuring the conveying efficiency.

[0040] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0041] Working principle: To sum up, by means of the above technical solutions of the present invention, when using the cryogenic loading arm, the cryogenic loading arm can be moved left and right through the electric slide rail 1, and the fixed stability and fixing effect of the cryogenic loading arm can be ensured through the electric push rod 9 and the fixed block 10;

[0042] When it is necessary to adjust the height of the cryogenic loading arm, the first motor 302 is started through the controller 11. Then, the rotating shaft of the first motor 302 drives the threaded rod 303 to rotate. Immediately, the threaded rod 303 drives the moving rod 304 and the limiting protrusion 305 to move in the limiting port 5. During the movement, the moving rod 304 contacts the diffusion cotton 308, and then the lubricating solution in the liquid storage tank 306 is conveyed to the conveying cotton thread 309 through the conveying cotton thread 309, so as to avoid the problem that it is inconvenient for the moving rod 304 to move or there is resistance during the moving adjustment;

[0043] When the fluid flow rate detected by the ultrasonic flowmeter 413 is low or small, the second motor 407 is started by the controller. Then, the rotating shaft of the second motor 407 drives the driving gear 408 to rotate. Immediately afterwards, the driving gear 408 engages with the driven gear 409, causing the adjusting plate 410 to rotate. When the adjusting plate 410 rotates, the moving plate 411 moves along the limiting groove and the adjusting groove 8, thereby realizing the adjustment of the fluid flow rate multiple times. Thus, the flow rate can be adjusted according to the fluid velocity, and further ensuring the conveying efficiency.
