Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of substations, specifically to a mine explosion-proof multi-module parallel intelligent substation. Background Technology
[0002] Although explosion-proof mobile substations for mining integrate high-rise buildings and are chamber-free, the dry-type transformer is completely enclosed by a steel explosion-proof shell. With no airflow underground, it relies solely on passive air self-cooling, leading to heat accumulation and extremely low heat dissipation efficiency. This becomes the primary bottleneck restricting capacity and stability. Current measures such as enlarging the shell and using corrugated heat sinks only increase size and weight, reduce flexibility, and still require larger tunnel cross-sections, failing to overcome the inherent self-cooling defect.
[0003] According to Chinese Patent No. CN221614499U, a mine-use explosion-proof mobile substation that is easy to install is disclosed. The substation includes a base plate welded to its bottom, with four legs fixed at each corner. Each leg has a groove inside, with a rotating bolt inserted into the groove. A rotating rod is rotatably mounted on the rotating bolt, and a caster wheel is fixed to the end of the rotating rod away from the rotating bolt. This invention, by providing a rotating rod with a caster wheel at the bottom within the groove of the leg, and the top of the rotating rod being an arc shape that mates with the groove, allows the rotating rod to rotate within the groove using the rotating bolt as a pivot. This mobile assembly allows the mine-use explosion-proof substation to provide vertical load-bearing capacity without hindering its movement, improving the stability of the substation and reducing the probability of production accidents.
[0004] However, existing multi-module parallel substations require manual operation by pressing the nearest high-voltage switch to complete the parallel operation. When the switch is closed, the system impedance drops sharply, which will generate a strong electric arc and an impact electromagnetic field. If the operator's hand forms a potential difference with the metal casing, it will cause electric shock to the user and power outage of the equipment. Utility Model Content

If the operator's hand forms a potential difference with the metal casing, it will cause electric shock to the user and power outage of the equipment.
[0006] The technical solution adopted to solve the above technical problems is: A mine-use explosion-proof multi-module parallel intelligent substation includes a multi-module parallel substation body. A high-voltage switch panel is fixed on the multi-module parallel substation body.

The sliding of the spring rod in the through hole of the sliding seat can change the rigid contact into a flexible contact.
[0009] As a preferred technical solution of this utility model, a movable base is fixed on the lower side of the multi-module parallel substation body, and a caster wheel is fixed on the bottom of the movable base.
[0010] As a preferred embodiment of this utility model, a third threaded rod is threadedly connected to the movable base, and a support plate is threadedly connected to the lower side of the third threaded rod. A through hole is opened on the right side of the support plate, and a second limiting rod is fixed to the lower side of the movable base.

[0011] As a preferred technical solution of this utility model, a telescopic base is fixed on the mobile base, and a telescopic plate is fixed on the telescopic base. The telescopic plate is fixed to the telescopic base by bolts, and a control panel is fixed on the telescopic plate. The control panel can control the movement of the motor and the electric telescopic bracket. The control panel has a built-in wireless transmission module. The height of the control panel can be infinitely adjusted by the telescopic plate. The built-in wireless transmission module can remotely receive ground commands and upload pressing results and switch status in real time, realizing "cloud inspection", reducing the number of people working underground and improving the level of intelligence.
[0012] The beneficial effects of this utility model are as follows: Because this utility model has a remote control module on the high-voltage switch panel, users can move the module up and down and horizontally and perform pressing operations through the control panel or remote wireless control, avoiding direct contact between the user and the high-voltage switch panel and improving equipment safety.

[0020] Example 1
[0021] exist Figure 1-4 This utility model provides a technical solution: a mine explosion-proof multi-module parallel intelligent substation, including a multi-module parallel substation body 1, a high-voltage switch panel 2 fixed on the multi-module parallel substation body 1, a sliding groove 3 on the multi-module parallel substation body 1, a movable plate 4 slidably connected in the sliding groove 3, a first threaded rod 5 connected in the sliding groove 3, the movable plate 4 being threadedly connected to the first threaded rod 5, a second threaded rod 6 and a first limiting rod 7 connected between the movable plates 4, a sliding seat 8 slidably connected to the first limiting rod 7, and the sliding seat 8 being threadedly connected to the second threaded rod 6. The sliding seat 8 is connected to an electric telescopic bracket 9, which in turn is fixed to an insulating pressing rod 10. The first threaded rod 5 and the second threaded rod 6 are driven by a motor. The motor drives the first threaded rod 5 to rotate, and the moving plate 4 moves laterally along the convex sliding groove 3 to achieve left and right positioning of the insulating pressing rod 10. The motor drives the second threaded rod 6 to rotate, and the sliding seat 8 moves back and forth along the first limit rod 7 to achieve front and back positioning of the insulating pressing rod 10. The dual-axis linkage enables the insulating pressing rod 10 to accurately reach any operating point on the high-voltage switch panel 2, completing intelligent inspection and remote opening and closing pressing.
[0022] In one aspect of this embodiment, there are two sliding grooves 3, the cross-section of which is convex. The cross-section of the moving plate 4 is also convex. A through hole is provided on the sliding seat 8. The electric telescopic bracket 9 consists of an electric telescopic rod and a mounting plate. A spring rod 18 is fixed on the mounting plate of the electric telescopic bracket 9. The spring rod 18 slides within the through hole of the sliding seat 8. An insulating pressing rod 10 is fixed to the end of the spring rod 18. The convex cross-section prevents the moving plate 4 from derailing from the sliding seat 8. When the electric telescopic rod extends, the mounting plate drives the spring rod 18 to slide down along the through hole. The spring rod 18 provides elastic buffering to avoid rigid impact damaging the switch.
[0023] In one aspect of this embodiment, a movable base 11 is fixed to the lower side of the multi-module parallel substation body 1. A caster wheel 12 is fixed to the bottom of the movable base 11. A third threaded rod 19 is threaded onto the movable base 11. A support plate 13 is threaded onto the lower side of the third threaded rod 19. A through hole is opened on the right side of the support plate 13. A second limiting rod 14 is fixed to the lower side of the movable base 11 and slides within the through hole of the support plate 13. A telescopic base 15 is fixed to the movable base 11, and a telescopic plate 16 is fixed to the telescopic base 15. The telescopic plate 16 is fixed to the telescopic base 15 by bolts. A control device is fixed to the telescopic plate 16. The control panel 17 controls the movement of the motor and the electric telescopic bracket 9. The control panel 17 has a built-in wireless transmission module, and the casters 12 enable the movement of the entire machine. By rotating the third threaded rod 19, the support plate 13 descends along the second limit rod 14 and presses against the ground, raising the casters 12 to complete the stable parking. The telescopic plate 16 rises and falls along the telescopic base 15. After adjusting the height of the control panel 17, the bolts are locked to accommodate different operator heights. The control panel 17 remotely sends and receives commands through the wireless module to drive the motors and the electric telescopic bracket 9 to work together, realizing unmanned intelligent operation and multi-module parallel control in an explosion-proof environment.
[0024] The working principle of this utility model is as follows: The control panel 17 receives remote commands via a wireless module, driving the first threaded rod 5 and the second threaded rod 6 to rotate, so that the moving plate 4 and the sliding seat 8 complete lateral and longitudinal linkage within the convex sliding groove 3, precisely positioning the insulating pressing rod 10 to any operating point on the high-voltage switch panel 2; the electric telescopic rod extends, the spring rod 18 slides down along the through hole and provides elastic buffering, and the insulating pressing rod 10 presses the switch with the set pressure, realizing unmanned opening and closing and intelligent inspection in an explosion-proof environment. The caster wheel 12 provides 360° movement, and rotating the third threaded rod 19 causes the support plate 13 to descend along the second limit rod 14 and press against the ground, lifting the caster wheel 12 to complete stable parking; the telescopic plate 16 rises and falls along the telescopic base 15, and locks after adjusting the height of the control panel 17, adapting to different operator heights.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
