[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 As shown, this utility model is an energy-saving and labor-saving cryogenic liquid filling device, including a support base 1 and a cryogenic liquid filling equipment body 7. The inner wall of the support base 1 is provided with an annular clamping mechanism 2. The annular clamping mechanism 2 includes a first motor 21 fixedly connected to the inner wall of the support base 1, four support bars 22, and a rotating shaft 23 rotatably connected to the inner wall of the support base 1. A first gear 24 is fixedly connected to the surface of the output shaft of the first motor 21. A limiting groove 25 is fixedly connected between the tops of the four support bars 22. Multiple sliding strips 26 are slidably connected to the inner wall of the limiting grooves 25. Clamping plates 27 are fixedly connected to each of the multiple sliding strips 26. The bottom of each of the multiple sliding strips 26 is fixedly connected to a connecting shaft 28, and the surface of the rotating shaft 23 is fixedly connected to a second gear 29. Multiple transmission bends 210 are opened through the second gear 29. By setting the annular clamping mechanism 2, the filling equipment can be clamped, making it stable and preventing it from loosening, thus preventing accidents during use. At the same time, this device is ingeniously designed and practical. Its bottom is equipped with a universal wheel device 3, which can easily slide on the ground, making it easier and less strenuous for operators to hold the filling head 10, i.e., the vacuum hose, to the filling vehicle interface, thereby reducing the number of operators and saving labor costs to a certain extent.

[0026] The bottom of the support base 1 is equipped with a caster wheel device 3, and the surface of the support base 1 is fixedly connected with a connecting frame strip 4.

[0027] A fixed base 5 is fixedly connected to the top of the connecting frame 4. A reciprocating tapping mechanism 6 is provided on the fixed base 5. By setting the reciprocating tapping mechanism 6, the transmission pipe 8 can be continuously tapped to remove the attached material and prevent sticking. By keeping the inner wall of the pipe clean, the liquid transportation resistance is reduced, and the cryogenic liquid can be filled through the pipe at a faster speed, thereby shortening the filling time and improving the overall filling efficiency.

[0028] The reciprocating tapping mechanism 6 includes a second motor 61 and a limiting shaft 62 fixedly connected to the fixed base 5. A transmission wheel 63 is fixedly connected to the surface of the output shaft of the second motor 61. A transmission groove 64 is opened on the surface of the transmission wheel 63. A tapping strip 65 is rotatably connected to the surface of the limiting shaft 62. A transmission shaft 66 is fixedly connected to the inner wall of the tapping strip 65. The transmission shaft 66 and the transmission groove 64 are compatible with each other.

[0029] The first gear 24 meshes with the second gear 29, and multiple connecting shafts 28 are respectively adapted to adjacent transmission bends 210.

[0030] There are four caster wheels 3, which are arranged in a rectangular array at the bottom edge of the support base 1. The caster wheels 3 can move in any direction. The design of multiple caster wheels 3 ensures the stability of the entire device. At the same time, it has a braking function. When using it, braking can keep the entire device stable.

[0031] A transfer pipe 8 is fixedly connected to the surface of the cryogenic liquid filling equipment body 7. The cryogenic liquid filling equipment body 7 is a core component of an energy-saving and labor-saving cryogenic liquid tanker filling device, including key parts such as a cryogenic liquid container, a filling device, a piping system, and safety protection devices. The cryogenic liquid container is used to store cryogenic liquids, such as liquid oxygen, nitrogen, and argon; the filling device is responsible for transporting the cryogenic liquid from the container to the tanker; the piping system connects all components to ensure smooth flow of the cryogenic liquid; and the safety protection device monitors and controls various parameters during the filling process to ensure operational safety. As this is existing technology, it will not be described in detail here. The cryogenic liquid filling equipment body 7 is electrically connected to an external power source and is controlled by an external program. A pumping control system 9 is connected to the transmission pipe 8, and a filling head 10 is connected to the pumping control system 9. The pumping control system 9 includes a pump body and a pipeline system. Its pump body adopts a high-vacuum multi-layer thermal insulation design to reduce the cold loss of cryogenic liquid and ensure temperature stability during transportation. The corresponding transportation volume can be adjusted through a preset program. As this is existing technology, it will not be described in detail here. The pumping control system 9 is electrically connected to an external power source and is controlled by an external program.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] The working principle of this utility model is as follows: First, the container 7 to be filled is placed on top of the limiting groove 25. Then, the first motor 21 is started, which drives the first gear 24 to rotate through the output shaft. When the first gear 24 rotates, it drives the second gear 29, which rotates on the support base 1 through the rotating shaft 23. When the second gear 29 rotates, it squeezes and drives the multiple connecting shafts 28 through multiple transmission bends 210. The multiple connecting shafts 28 drive the multiple sliding strips 26 to move inward in the inner wall of the limiting groove 25. When the multiple sliding strips 26 move, they drive the multiple clamping plates 27 to move synchronously and fit against the surface of the container 7 to be filled, clamping it tightly. The device is then stabilized and moved to the designated location via multiple caster wheels 3. The filling interface 10 is then inserted into the filling vehicle. The filling control valve 9 is then controlled and the filling pump 7 is started to fill the liquid. When the cryogenic liquid passes through the delivery pipe 8 and is then delivered to the vehicle through the filling interface 10, the second motor 61 is started, which drives the transmission wheel 63 to rotate through the output shaft. The rotation of the transmission wheel 63 squeezes and drives the transmission shaft 66 through the transmission slot 64. The transmission shaft 66 drives the beater bar 65 to swing back and forth on the surface of the limit shaft 62, so that the beater bar 65 continuously beats the delivery pipe 8, causing the material attached to the delivery pipe 8 to fall off and allowing it to be delivered smoothly.
