Description

Technical Field

[0001] This utility model relates to the field of safety protection device technology, and in particular to a mine electronic fence protection device. Background Technology

[0002] Electronic fences, as an important security device, are widely used in perimeter security and area isolation. By combining physical barriers with electronic alarm systems, they effectively prevent unauthorized entry of personnel or objects. In special working environments such as mining, setting up fences plays a crucial role in ensuring operational safety, clearly defining the boundaries of dangerous areas, and preventing unauthorized personnel from entering.

[0003] Currently, the fences used in mines are fixed physical or electronic fences, whose height and shape are difficult to change after installation. However, mining operations are highly dynamic, requiring large engineering vehicles or equipment to enter and exit specific work areas. If temporary passage is required, the fences need to be dismantled and reinstalled, which is not only time-consuming and labor-intensive, but also creates a safety management gap during the dismantling period. Therefore, the existing fences are not flexible enough to meet the dynamic operation needs of mining areas.

[0004] In addition, mining areas are mostly located in open fields and are constantly exposed to harsh natural environments such as strong winds. The support structure of traditional fences is relatively simple and has limited wind resistance. When encountering strong winds, tall fences are prone to swaying, collapsing or even being damaged. Not only do they lose their original protective function, but they can also cause secondary injuries to personnel or equipment after collapsing, posing serious safety hazards.

[0005] Therefore, this utility model proposes a fence protection device for a mine electronic vehicle recorder to address the shortcomings of the existing technology. Utility Model Content

[0010] Preferably, the mine electronic fence protection device further includes a magnetic block and a magnetic sliding column. The magnetic block is installed on the front side of the support column, and the magnetic sliding column is correspondingly arranged on the sliding fence. They are used to magnetically attract each other after the sliding fence slides to a designated position, providing auxiliary fixation.

[0011] Preferably, the pull plate and the sliding fence are respectively provided with locking holes for inserting the pin.

[0012] Preferably, a limiting through hole is provided on the fixed plate, and the limiting post passes through the limiting through hole and can slide along the axial direction of the limiting through hole to limit the movement range of the pulling plate.

[0013] Preferably, the support base has multiple sliding grooves and multiple sliding plates slidably connected to each other to form multi-point support.

[0014] Preferably, the support mechanism further includes a counterweight, which forms a receiving space between the support base and the sliding plate to accommodate the counterweight after the sliding plate is pulled out from the support base.

[0015] Preferably, the bolt is threaded onto the sliding plate.

[0016] Preferably, the mine electronic fence protection device further includes electronic components and a detection head. The electronic components are installed inside the support column, and the detection head is set on the sliding fence and the fixed fence.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 5 This utility model provides a mine electronic fence protection device, which aims to solve the problems of poor flexibility caused by the fixed height of existing mine fences and insufficient stability of the support structure in windy outdoor environments.

[0030] like Figure 1As shown, the mine electronic fence protection device includes a support column 1 and a fixed fence 11 and a sliding fence 8 installed on the support column 1. The support column 1 has a sliding groove 3 inside, and the sliding fence 8 is slidably connected to the inner wall of the sliding groove 3, so that the sliding fence 8 can move up and down along the length of the support column 1. The fixed fence 11 is fixedly connected to the upper part of the support column 1. Electronic components are installed inside the support column 1. Both the sliding fence 8 and the fixed fence 11 are equipped with detection heads. The detection heads are connected to the electronic components through wires. When a foreign object touches the fence, the detection head monitors it and realizes a remote alarm through the electronic components. A support mechanism 2 is connected to the bottom of the support column 1. The support mechanism 2 is used to provide a stable support foundation for the entire device.

[0031] The mine electronic fence protection device also includes a pull plate 4, a fixing plate 5, a limiting post 6 and a pin 7 for locking the height of the sliding fence 8. Furthermore, these components form a specific structural fit and connection relationship with the support post 1 and the sliding fence 8.

[0032] Please refer to Figure 1 , Figure 4 and Figure 5 The pull plate 4 is slidably mounted on the top of the support column 1. A fixing plate 5 is fixed to the outside of the support column 1 by welding or screws. A limiting through hole is provided on the fixing plate 5. A limiting post 6 passes through the limiting through hole of the fixing plate 5 and is fixedly connected to the pull plate 4. The sliding engagement of the limiting post 6 in the limiting through hole limits the range of vertical movement of the pull plate 4, thereby preventing the pull plate 4 from moving excessively. Two pins 7 are provided on the pull plate 4. Locking holes are provided on the pull plate 4 and the sliding fence 8 respectively. When the sliding fence 8 is pulled up to the predetermined height, the pull plate 4 is lifted up to align the locking hole on the pull plate 4 with the locking hole on the sliding fence 8. The pins 7 are passed through the aligned locking holes to achieve reliable positioning and locking of the sliding fence 8, ensuring that the sliding fence 8 will not slide accidentally when subjected to external impact.

[0033] Please refer to Figure 1 and Figure 3 To further enhance the stability of the locking mechanism, a magnetic block 10 is installed on the front side of the support column 1, and a corresponding magnetic sliding column 9 is provided on the sliding fence 8. After the sliding fence 8 slides to the designated position, the front end of the magnetic sliding column 9 and the magnetic block 10 are attracted to each other by magnetic force, providing a second layer of fixation for the sliding fence 8 and effectively reducing the slight displacement caused by factors such as vibration.

[0034] As a preferred embodiment, please refer to Figure 1 and Figure 2The support mechanism 2 includes a support block 201 fixedly connected to the bottom of the support column 1 and a support base 202 fixed to the bottom of the support block 201. The support base 202 has a sliding groove, and a sliding plate 203 that can be pulled out from the support base 202 is slidably connected to the inner wall of the sliding groove. The sliding plate 203 has a fixing hole, and a bolt 204 can pass through the fixing hole to anchor the sliding plate 203 to the ground. By pulling out the sliding plate 203 and fixing it with the bolt 204, the support area of ​​the entire device and the connection strength with the ground are increased, which significantly improves the anti-overturning ability.

[0035] As another preferred embodiment, in order to further increase the supporting force, after the sliding plate 203 is pulled out from the support base 202, a receiving space for accommodating the counterweight 205 is formed between the support base 202 and the sliding plate 203. By placing the counterweight 205, such as a concrete block or a metal block, in the receiving space, the overall weight of the mine electronic fence protection device can be effectively increased, the center of gravity can be lowered, and thus a stronger supporting force can be provided to resist external forces such as strong winds.

[0036] As another preferred embodiment, the bolt 204 is threaded onto the sliding plate 203. When it is necessary to anchor the sliding plate 203 to the ground, the bolt 204 can be tightened downwards without the need for additional fasteners.

[0037] In another preferred embodiment, the support base 202 may have multiple sliding grooves evenly distributed along the circumference, and multiple sliding plates 203 are slidably connected to each other, so that the support feet can extend from multiple directions to form a more stable multi-point support structure.

[0038] Working principle: When a higher level of protection is required by raising the fence, the worker pulls the sliding fence 8 upward. Since the sliding fence 8 is slidably connected to the groove 3 inside the support column 1, the sliding fence 8 will move smoothly upward along the groove 3 until it reaches the top of the fixed fence 11, completing the raising of the fence. Then, the pull plate 4 is lifted upward. Since the limiting post 6 slides in the limiting through hole of the fixed plate 5, the stroke of the pull plate 4 is limited and will not move excessively. When the locking hole on the pull plate 4 is aligned with the locking hole on the sliding fence 8, the pin 7 is pulled out from the pull plate 4 and inserted into the aligned locking hole. At this time, the pin 7 firmly fixes the pull plate 4 and the sliding fence 8 together. At the same time, the magnetic sliding post 9 on the sliding fence 8 and the magnetic block 10 on the support column 1 attract each other. Through the mechanical locking of the pin 7 and the auxiliary fixing of the magnetic attraction, the structural stability of the sliding fence 8 at the high position is ensured, effectively preventing movement or abnormal noise caused by shaking. Thus, the fence can be raised when needed to provide better protection.

[0039] When the mining area encounters severe weather such as strong winds and it is necessary to enhance the support stability of the fence, workers can pull out the sliding plate 203 from the sliding groove of the support base 202 to expand the bottom support area of ​​the entire device. Then, bolts 204 are passed through the fixing holes on the sliding plate 203 and tightened to fix it to the ground, achieving rigid anchoring of the mining electronic fence protection device to the ground. To further strengthen the support, a counterweight 205 can be placed in the space formed between the support base 202 and the pulled-out sliding plate 203. By increasing the overall weight of the mining electronic fence protection device, it can resist wind force. Through the synergistic effect of expanding the support surface, ground anchoring, and increasing the counterweight, stronger support can be provided when the wind is blowing, ensuring the safety of the fence itself.
