[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0026] according to Figure 1-6 The present invention provides a mining refrigeration device, comprising: a refrigerator 1 and a drive structure 2.

[0027] Example 1:

[0028] Drive structure 2 is disposed on both sides of the bottom end of refrigerator 1. Drive structure 2 includes a rotating rod 21, a contact rod 22, a connecting frame 23, and a rotating wheel 24. Rotating rod 21 is rotatably connected to refrigerator 1. Contact rod 22 is connected to rotating rod 21. Connecting frame 23 is connected to rotating rod 21. Contact rod 22 and connecting frame 23 are not parallel. Rotating wheel 24 is rotatably disposed on connecting frame 23.

[0029] When the refrigerator 1 needs to be moved, the interference rod 22 is rotated to rotate the rotating rod 21, which drives the connecting frame 23 to rotate. The connecting frame 23 rotates accordingly and causes the interference rod 22 to interfere with the ground. Since the interference rod 22 is not parallel to the rotating rod 21, when the two rotate, one of them will touch the ground first. At this time, the interference rod 22 interferes with the ground, and the rotating wheel 24 on the connecting frame 23 is some distance away from the ground. At this time, the refrigerator 1 is pushed or pulled, and the refrigerator 1 moves, which drives the driving structure 2 to move, so that the interference rod 22 is driven, and the pressure between the interference rod 22 and the ground increases, so that the interference rod 22 is subjected to a certain friction force, making it difficult for the interference rod 22 to move forward, and the interference rod 22 can drive the rotating rod 21 to rotate, so that the interference rod 22 will rotate and lift a part of the refrigerator 1. When the interference rod 22 rotates so that the interference rod 22 is perpendicular to the bottom plane of the refrigerator 1, the refrigerator 1 is lifted to the highest point, and the interference rod 22 continues to rotate, causing the position of the refrigerator 1 to drop. At the same time, the rotating rod 21 drives the connecting frame 23 to rotate, so that the rotating wheel 24 contacts the ground. Then, the contact rod 22 is rotated so that the rotating wheel 24 contacts the ground. When the rotating wheel 24 rotates with the rotating rod 21, the position of the refrigerator 1 is raised until the connecting frame 23 is perpendicular to the bottom plane of the refrigerator 1. At this time, the refrigerator 1 is supported by the connecting frame 23 and can be rotated by the rotating wheel 24. During the above process, the height of the refrigerator 1 changes frequently. It is necessary to control the refrigerator 1 to prevent it from falling suddenly. Then, the connecting frame 23 is fixed so that the refrigerator 1 can be moved by the roller. That is, the present invention can move the refrigerator 1 by rolling the rotating wheel 24 through the driving structure 2, which makes it easier to transport and arrange the refrigerator 1. When it is necessary to release the rotating wheel 24 to drive the refrigerator 1 to rotate, the fixing of the connecting frame 23 is released, and the refrigerator 1 is moved in the opposite direction in the same way. The driving structure 2 can be gradually reset so that the bottom end of the refrigerator 1 contacts the ground to prevent the rotating wheel 24 from contacting the ground and causing less friction and difficulty in placement.

[0030] The refrigerator 1 includes a fixed structure 11. The fixed structure 11 includes a fixed frame 111. The fixed frame 111 is movable relative to the drive structure 2. The fixed frame 111 matches the drive structure 2 so that the drive structure 2 can be clamped on the fixed frame 111. The fixed structure 11 also includes a rack 112, a gear 113, a connecting rod 114, a worm gear 115, and a worm 116; the worm gear 116 matches the worm gear 115; the connecting rod 114 is connected to the worm gear 115; the gear 113 is arranged on the connecting rod 114; the rack 112 is arranged on one side of the fixed frame 111; and the gear 113 is meshed with the rack 112. The rotating wheel 24 includes a gripping rod 241. The gripping rod 241 is arranged along the circumference of the rotating wheel 24.

[0031] When the connecting frame 23 is perpendicular to the bottom plane of the refrigerator 1 and the connecting frame 23 needs to be fixed, the worm 116 is rotated to rotate the worm wheel 115 matched thereto. The gear 113 is connected to the worm wheel 115 via the connecting rod 114, causing the gear 113 to rotate. When the gear 113 rotates, it drives the rack 112 to move, and the rack then causes the fixed frame 111 to move toward the connecting frame 23. The fixed frame 111 is matched with the driving structure 2, so that when the fixed frame 111 moves, the connecting frame 23 and the interference rod 22 are stuck on the fixed frame 111, that is, the connecting frame 23 and the interference rod 22 cannot rotate, so that the rotating wheel 24 drives the refrigerator 1 to remain stable when moving. When it is necessary to release the fixation, the worm 116 is reversed. In addition, after the driving structure 2 is reset, the connecting frame 23 can also be moved so that the interference rod 22 can be placed on the fixed frame 111 to prevent the interference rod 22 from contacting the ground and causing an impact. A gripping rod 241 is also circumferentially provided on the rotating wheel 24 to increase the friction between the driving structure 2 and the ground, thereby preventing the device from sliding on uneven ground or slopes.

[0032] The interference rod 22 includes: a main rod 221, a telescopic rod 222, and a telescopic spring 223. A telescopic groove 2211 is provided on the end of the main rod 221 away from the rotating rod 21. The telescopic rod 222 is telescopically arranged in the telescopic groove 2211. One end of the telescopic spring 223 is arranged in the telescopic groove 2211, and the other end is connected to the side of the telescopic rod 222 close to the rotating rod 21. The refrigerator 1 also includes: a positioning structure 12. The positioning structure 12 is arranged on one side of the rotating rod 21. The positioning structure 12 includes: an upper splint 121 and a lower splint 122. The positioning structure 12 has a positioning opening 123 between the upper splint 121 and the lower splint 122. The side of the lower splint 122 away from the upper splint 121 is an inclined surface. The inclined surface is inclined downward from the side away from the rotating rod 21 to the other side.

[0033] A telescopic rod 222 is provided at the end of the contact rod 22 away from the rotating rod 21, so that when the contact rod 22 contacts the ground, the telescopic rod 222 first contacts the ground and contracts simultaneously. When the contact rod 22 encounters an unstable ground, the telescopic rod 222 can automatically adjust accordingly when the contact rod 22 contacts the ground, thereby maintaining the stability of the overall structure. At the same time, the telescopic rod 222 can also be partially extended into the telescopic slot 2211 before the telescopic rod 222 of the contact rod 22 contacts the ground. When the contact rod 22 just contacts the ground, the telescopic rod 222 will exert a force on the ground, thereby increasing the friction between the contact rod 22 and the ground, making it more difficult for the contact rod 22 to slide on the ground, which is conducive to lifting the refrigerator 1. When the interference rod 22 rotates to a certain position, the telescopic rod 222 will contact the inclined surface of the lower splint 122 of the positioning structure 12. At this time, the telescopic rod 222 will be subjected to the component force toward the inside of the telescopic groove 2211, causing the telescopic rod 222 to shrink, that is, the overall length of the interference rod 22 becomes shorter, causing the interference rod 22 to move to the positioning port 123. At the same time, the telescopic rod 222 no longer conflicts with the lower splint 122, rebounds, and is stuck in the positioning port 123. At this time, the telescopic rod 222 is attached to the upper splint 121 and the lower splint 122, and is difficult to move, so that the interference rod 22 is positioned at this time, that is, the driving structure 2 is positioned as a whole, so that when the connecting frame 23 is fixed by the fixing structure 11 later, the driving structure 2 is difficult to move, which is convenient for fixation.

[0034] Example 2:

[0035] The connecting frame 23 includes a limit block 231, a fixed rod 232, and a resistance block 233. The fixed rod 232 is disposed on the side of the rotating wheel 24 close to the rotating rod 21. The limit block 231 is rotatably mounted on the fixed rod 232. The resistance block 233 is disposed on one side of the limit block 231. A sliding groove 234 is formed on the connecting frame 23. A slider 235 is disposed within the sliding groove 234 of the connecting frame 23. The slider 235 can slide within the sliding groove 234 to move away from or closer to the resistance block 233. The slider 235 is disposed on the side of the limit block 231 away from the resistance block 233. A resistance spring 236 is disposed at one end of the sliding groove 234 close to the resistance block 233 of the connecting frame 23. The resistance spring 236 is connected to the slider 235. A clamping groove 237 is formed on the connecting frame 23. The resistance block 233 extends into the clamping groove 237. The resisting block 233 is movable in the slot 237 .

[0036] A fixing rod 232 is provided on the side of the rotating wheel 24 close to the rotating rod 21, and the limit block 231 is rotatably mounted on the fixing rod 232. When the rotating wheel 24 rotates, the gripping rod 241 can interfere with the limit block 231, driving the limit block 231 to rotate, and an interference block 233 is provided on one side of the limit block 231, so that when the rotating wheel 24 moves forward, the gripping rod 241 can cause the limit block 231 to rotate, and when the rotating wheel 24 moves backward, the limit block 231 will interfere with the interference block 233, that is, the rotating wheel 24 cannot rotate backward, so that when moving upward or in some more complex terrain, the rotating wheel 24 tends to move backward, which can easily cause the rotating wheel 24 to move backward during movement. However, the rotating wheel 24 of the present invention can prevent this situation, which is conducive to the advancement of the device. The connecting frame 23 is provided with a slider 235 on the side of the limit block 231 away from the interference block 233, so that when the limit block 231 is driven by the advancing gripping rod 241, it will interfere with the slider 235, causing it to move in the sliding groove 234. At the same time, the interference spring 236 is stretched, so that when the gripping rod 241 rotates away from the limit block 231, the interference spring 236 rebounds, causing the slider 235 to drive the limit block 231 to quickly return to its original position, thereby preventing the limit block 231 from rotating too much and making it difficult to return to its original position, resulting in it failing to function. A slot 237 is also provided in the connecting frame 23, which allows the interference block 233 to be fully inserted so that the limit block 231 can be rotated in that direction, so that when the device needs to move backward, corresponding adjustments can be made to meet the needs. At the same time, the interference spring 236 can be in a stretched state from the beginning, so that after the interference block 233 is fully inserted into the slot 237, the interference spring 236 will drive the limit block 231 to rotate a certain range through the slider 235, so that the gripping rod 241 will no longer conflict with it when it rotates, avoiding unnecessary conflict or collision between the gripping rod 241 and the limit block 231.

[0037] The working principle and use process of the present invention:

[0038] When the refrigeration device needs to be transported, the telescopic rod 222 of the interference rod 22 is first extended into a part of the telescopic groove 2211 to compress the telescopic spring 223, and then the interference rod 22 is rotated to rotate the rotating rod 21, and the rotating rod 21 drives the connecting frame 23 to rotate, so that the rotating wheel 24 and the gripping rod 241 rotate accordingly. When the interference rod 22 rotates to contact with the ground, it stops. At this time, the telescopic spring 223 rebounds, causing the telescopic rod 222 to contact with the ground, and then push or pull the refrigerator 1 to make the refrigerator 1 move forward. The refrigerator 1 drives the rotating rod 21 forward, and the interference rod 22 contacts the ground, causing the interference rod 22 to be When the contact rod 22 rotates to the positioning structure 12, the telescopic rod 222 conflicts with the inclined surface of the lower splint 122, causing the telescopic rod 222 to extend into the telescopic groove 2211, and the telescopic spring 223 is compressed. At the same time, the telescopic rod 222 continues to rotate until the contact rod 22 moves to the positioning opening 123, and at the same time, the telescopic rod 222 disengages from the lower splint 122, causing the telescopic spring 223 to rebound, causing the telescopic rod 222 to extend into the positioning opening 123 and be stuck by the upper splint 121 and the lower splint 122. At this time, the gripping rod 241 contacts the ground, and the connecting frame 23 is perpendicular to the bottom plane of the refrigerator 1. Then, the worm 116 is rotated to rotate the worm wheel 115, which in turn drives the connecting rod 114 and the gear 113 to rotate. When the gear 113 rotates, the rack 112 is driven to move, and the rack drives the fixed frame 111 to move toward the connecting frame 23. The fixed frame 111 is matched with the driving structure 2, so that when the fixed frame 111 moves, the connecting frame 23 and the interference rod 22 are stuck on the fixed frame 111, that is, the connecting frame 23 and the interference rod 22 cannot rotate, so that the rotating wheel 24 drives the refrigerator 1 to move smoothly. Then, the refrigeration device can be moved.

[0039] In summary, the present invention adds a driving structure to the refrigerator, so that the refrigerator can be moved by the resistance rod, and at the same time, the rotating wheel is driven to contact the ground, so that the refrigerator can be moved by the rotating wheel, which facilitates the transportation and arrangement of the refrigerator.
