Description

Technical Field

[0001] The utility model relates to the technical field of electronic fences, in particular to an electronic fence protection device. Background Art

[0002] Electronic fence is the most advanced perimeter anti-theft alarm system. It consists of a high-voltage electronic pulse host and a front-end detection fence. The high-voltage electronic pulse host generates and receives high-voltage pulse signals, and can generate alarm signals when the front-end detection fence is in a state of touching the net, short circuit, or disconnection, and sends the intrusion signal to the security alarm center; the front-end detection fence is a tangible perimeter composed of components such as rods and metal wires. The electronic fence is an active intrusion prevention fence that counterattacks against intrusion attempts, repel intruders, delay the intrusion time, and does not threaten human life. It also sends the intrusion signal to the monitoring equipment of the security department to ensure that the management personnel can understand the situation of the alarm area in time and deal with it quickly. With its unique performance, the electronic fence protection device is widely used in substations, power plants, water plants, factories, industrial centers, industrial and mining enterprises, material warehouses, residential areas, villa areas, schools, airports, aquaculture and livestock farms, government agencies, key cultural relics sites, military facilities, prisons, detention centers and other places with walls or where walls are needed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0022] The present utility model provides an electronic fence protection device as Figures 1-4 shown, including a base 1. The middle of the upper surface of the base 1 is movably provided with a support plate 2 through a pin shaft. A chute 3 is opened in the middle of the support plate 2. A slide seat 4 is slidably arranged inside the chute 3. The middle part of the inner side of the slide seat 4 is movably provided with a tension pulley 5 through a bearing. A plurality of guide pulleys 6 are arranged on both sides and at the top of the support plate 2. Both sides of the guide pulley 6 are movably provided with support seats 7 through bearings, and the support seats 7 are fixedly arranged outside the support plate 2. A fence wire 8 is arranged outside the guide pulley 6, and the fence wire 8 is arranged outside the tension pulley 5;

[0023] Specifically, movable seats 9 are movably arranged on both sides of the sliding seat 4 through bearings, and connecting seats 10 are movably arranged at the bottom ends of both sides of the support plate 2 through pin shafts. A tension spring 11 is fixedly arranged between the movable seat 9 and the connecting seat 10. The tension spring 11 can act on the tension pulley 5 to ensure that the fence wire 8 remains in a taut state.

[0024] More specifically, a plurality of connecting rods 12 are fixedly arranged on both sides of the support plate 2, and an extension plate 13 is fixedly arranged at one end of the connecting rod 12. A fixed frame 14 is fixedly arranged on the outer side of the extension plate 13, and strip-shaped grooves are formed through both sides of the fixed frame 14. A sliding rod 15 is slidably arranged inside the fixed frame 14. A positioning seat 16 is movably arranged in the middle of the sliding rod 15 through a pin shaft. Positioning springs 17 are fixedly arranged at both ends of the positioning seat 16, and one end of each positioning spring 17 is fixedly arranged on the inner wall of the fixed frame 14. The positioning springs 17 can assist in the reset of the sliding rod 15 to facilitate the automatic reset of the support plate 2.

[0025] Moreover, both ends of the sliding rod 15 are movably arranged with support arms 18 through pin shafts. The support arms 18 and the bottom ends of the extension plates 13 are both movably arranged with supports 19 through pin shafts, and the supports 19 are fixedly arranged on the upper surface of the base 1. The extension plates 13, the support arms 18 and the base 1 form a triangular structure, which can play an auxiliary supporting role for the support plate 2.

[0026] Furthermore, installation grooves 20 are formed at the four corners of the upper surface of the base 1, and the installation grooves 20 are arranged in a strip-shaped structure for the installation and fixation of the base 1.

[0027] Working principle of the utility model:

[0028] When the device is in use, the base 1 can be installed and fixed through the installation grooves 20 and fasteners such as expansion bolts. The fence wire 8 can be installed under the guidance of the tension pulley 5 and a plurality of guide pulleys 6. When the device encounters strong winds, the support plate 2 rotates around the pin shaft at its bottom end due to the action of the strong wind. At this time, the support plate 2 drives the extension plate 13 to move, and the triangular structure formed by the extension plate 13, the support arm 18 and the base 1 changes. During this process, the sliding rod 15 at the top end of the support arm 18 slides in the fixed frame 14 to achieve the unloading protection of the support plate 2. When the strong wind disappears, the sliding rod 15 and the positioning seat 16 are reset under the action of the positioning spring 17. At this time, the support plate 2 is reset. When the trees outside the fence fall due to strong winds, the fence wire 8 is stretched by the extrusion of the trees. At this time, the fence wire 8 drives the tension pulley 5 to move, and the tension pulley 5 drives the sliding seat 4 to slide in the chute 3 to achieve the release of the fence wire 8, so as to avoid the fence wire 8 being squeezed and driving the support plate 2 to fall. When the trees are cleared, the tension pulley 5 is reset under the action of the tension spring 11. At this time, the fence wire 8 returns to a taut state to ensure the normal use of the electronic fence.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
