As the core equipment for underground power supply in coal mines, the safety and stability of mobile substations are directly related to the production safety and efficiency of mines. However, traditional mobile substations have many deficiencies in protection, such as low protection level and too troublesome movement. These problems have seriously restricted the development of the coal mining industry.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN220022089U) discloses a protective mobile substation, including a base, a transformer, a bracket and a protective device.

By setting the connecting piece 4 hinged between the two parts of the side guard plate 3, the side guard plate 3 can be folded in the process of being driven down by the moving block 7, reducing the area blocked by the side guard plate 3, and facilitating the staff to inspect and maintain the substation body 1. A first motor 6 is fixedly installed on the top of the protective column 2, and a through groove is provided on one side of the protective column 2 at the bottom of the first motor 6. A through groove is also provided on the opposite side of the protective column 2 facing the through groove. A movable connecting rod 18 is installed in the through groove, and one end of the connecting rod 18 is fixedly connected to one side of the moving block 7. By installing the first motor 6 on the top of the protective column 2, the screw rod 8 can be driven to rotate by the first motor 6. By setting one end of the connecting rod 18 to be fixedly connected to one side of the moving block 7, when the device moves the moving block 7 by rotating the screw rod 8, the other three moving blocks 7 will be lifted and lowered together.

[0024] In specific implementation, when the device is used normally, it can be Figure 1 As shown, the first motor 6 is started to drive the screw rod 8 to rotate, so that the moving block 7 is raised and lowered, and the side guard plate 3 is rotatably connected to one side of the moving block 7, and the two side guard plates 3 are connected by a connecting piece 4.

[0027] Embodiment 2

[0028] Reference Figure 1-4 The utility model provides a protective mobile substation: a mounting base 20 is fixedly connected to the bottom of the mounting plate 5, a cavity is opened inside the mounting base 20, a second motor 9 is fixedly installed on the top surface of the inner wall of the cavity, a rotatable main gear 10 is connected to the bottom of the second motor 9, a gear ring 11 and a rotatable sub-gear 12 are rotatably installed on the bottom surface of the inner wall of the cavity, a moving column 13 is connected to the internal thread of the sub-gear 12, the main gear 10 is meshed with the gear ring 11, and the gear ring 11 is meshed with the main gear 10 and the sub-gear 12 at the same time, a receiving cavity 14 is arranged on the top surface of the cavity opened inside the mounting base 20, and the moving column 13 is provided with a plurality of gears. The top is in the accommodating chamber 14, the bottom end of the moving column 13 is connected to the moving wheel 16, and the bottom end of the mounting seat 20 is fixedly connected to the contact sleeve 15. The main gear 10 is meshed with the gear ring 11, and the gear ring 11 is meshed with the main gear 10 and also with the sub-gear 12, so that the device can drive the main gear 10, the gear ring 11 and the sub-gear 12 to rotate together after starting the second motor 9. The top of the moving column 13 is arranged in the accommodating chamber 14, and the top of the moving column 13 is arranged to have the same area as the top surface of the inner wall of the accommodating chamber 14, so that the moving column 13 will not fall off easily, and the moving column 13 is also limited by lateral rotation.

[0029] During specific implementation, when the device needs to be fixed at a certain place for use, the second motor 9 can be started. After the second motor 9 is started, the gear ring 11 is driven to rotate, and the gear ring 11 is meshed with the sub-gear 12, so the sub-gear 12 will be driven to rotate, and the internal thread of the sub-gear 12 is connected with a moving column 13, and the bottom of the moving column 13 is fixedly connected to the moving wheel 16. Therefore, after the sub-gear 12 rotates, the moving column 13 will be driven to rise, so that the moving wheel 16 is separated from the bottom surface, and the abutment sleeve 15 is directly in contact with the bottom surface, preventing the device from running off the track during subsequent use. When it is necessary to move, the second motor 9 can be reversed to make the moving wheel 16 contact the ground again.

[0032] When using the utility model, when the device is used normally, it can be Figure 1 As shown, the first motor 6 is started to drive the screw rod 8 to rotate, so that the moving block 7 is raised and lowered, and the side guard plate 3 is rotatably connected to one side of the moving block 7, and the two side guard plates 3 are connected by a connecting piece 4. Therefore, when the moving block 7 rises, the side guard plate 3 will be driven to stand up, which not only protects the substation body 1, but also prevents workers from accidentally touching the substation body 1.

[0033] When the substation body 1 needs to be inspected and maintained, the first motor 6 can be used to drive the moving block 7 to descend. After the moving block 7 descends, it will drive the side guard plate 3 to descend. During the descent process of the side guard plate 3, it will fold itself, reducing the space occupied by the side guard plate 3. At the same time, the substation body 1 will be directly exposed to the maintenance personnel, making it convenient to inspect the substation body 1.

[0034] By providing a side guard plate 3 and arranging the side guard plate 3 to be rotatably connected to one side of the moving block 7, the substation body 1 in the device can be fully protected during normal use, so that workers are not likely to accidentally touch the substation body 1, the substation body 1 is not easily affected by external factors, and the device can be more conveniently maintained.

[0035] When the device needs to be fixed at a certain place for use, the second motor 9 can be started. After the second motor 9 is started, the gear ring 11 is driven to rotate, and the gear ring 11 is meshed with the sub-gear 12, so the sub-gear 12 will be driven to rotate, and the internal thread of the sub-gear 12 is connected with a moving column 13, and the bottom of the moving column 13 is fixedly connected to the moving wheel 16. Therefore, after the sub-gear 12 rotates, the moving column 13 will be driven to rise, so that the moving wheel 16 is separated from the bottom surface, and the abutment sleeve 15 is directly in contact with the bottom surface, so as to prevent the device from deviating during subsequent use. When it is necessary to move, the second motor 9 can be reversed to make the moving wheel 16 contact the ground again.

[0036] By setting the internal thread of the sub-gear 12 to connect the moving column 13, the device can quickly complete the conversion between movement and fixation during use. Compared with the traditional device that can only be moved by vehicle, the use of this utility model is simpler and more practical.
