Description

Technical Field

[0001] This utility model relates to the field of infrared technology, specifically to an infrared anti-intrusion device. Background Technology

[0002] Currently, when it is necessary to isolate a certain area, the common method is to set up a cordon, such as at construction sites or accident handling sites. Workers first place barriers at equal intervals along the edge of the site, and then stretch a retractable belt or safety chain between every two barriers to remind pedestrians that passage is prohibited. This serves two purposes: preventing external interference with the isolated area and preventing external factors from entering the site and causing an accident.

[0003] However, setting up a warning line requires at least two people to lay the barriers and retractable belts one grid at a time. Moreover, due to the weight of the retractable belts, adjacent barriers cannot be too far apart, which limits the speed of warning line construction. Furthermore, although the warning line serves its purpose of alerting pedestrians after it is laid, the on-site environment is usually quite complex, and people or objects may accidentally cross the warning line. Because no one is constantly watching the warning line, even if someone crosses it, sometimes it will not be noticed.

[0004] For example, the infrared anti-intrusion alarm system disclosed in patent document CN211669724U includes an infrared signal generating unit, an alarm unit, and a smart bracelet. The infrared signal generating unit includes a transmitting component and a receiving component arranged opposite to each other. The alarm unit and the smart bracelet are connected to the infrared signal generating unit through a wireless communication module to respond to the control signal emitted by the infrared signal generating unit and to sound an alarm. By setting up a set of transmitters and receivers, a range of 50-100 meters can be achieved. Compared with the traditional warning line structure, it is simpler and easier to manufacture. Existing infrared anti-intrusion devices are generally directly exposed to the outside, which is easy to be interfered with by external forces. At the same time, it is inconvenient to adjust the height, which makes it more troublesome to use. Utility Model Content

[0027] Example 1:

[0028] Please see Figure 1-4An infrared anti-intrusion device includes an infrared transmitter 1 and an infrared receiver 2. Both the infrared transmitter 1 and the infrared receiver 2 are externally equipped with protective components 3. Each protective component 3 includes a protective housing 301. A first motor 302 is fixedly connected to the bottom of the protective housing 301, and a protective plate 303 is fixedly connected to the output shaft of the first motor 302. Each of the two protective housings 301 has a lifting component 4 at its bottom. Each lifting component 4 includes a support column 401. A second motor 402 is fixedly connected to the bottom of the inner cavity of the support column 401, and a threaded rod 403 is fixedly connected to the output shaft of the second motor 402. Sliding rods are mounted on both sides of the inner cavity of the support column 401. A movable rod 404 is connected to the movable rod 404. A threaded cylinder 405 is embedded in the inner cavity of the movable rod 404. The threaded rod 403 is threadedly connected to the threaded cylinder 405. The top of the movable rod 404 is fixedly connected to the protective box 301. By setting an infrared transmitter 1 and an infrared receiver 2, infrared surveillance of 50-100 meters can be achieved. By setting a protective component 3, the infrared transmitter 1 and the infrared receiver 2 can be protected from direct exposure to the outside and from impacts from external hard objects, which could cause damage. By setting a lifting component 4, the user can easily adjust the height of the infrared transmitter 1 and the infrared receiver 2, improving the flexibility of the surveillance.

[0029] Example 2:

[0030] Please see Figure 1-4 An infrared anti-intrusion device includes an infrared transmitter 1 and an infrared receiver 2. A sliding groove 5 is provided on both sides of the inner cavity of a support column 401. A slider 6 is slidably connected to the inner cavity of the sliding groove 5. The end of the slider 6 away from the sliding groove 5 is fixedly connected to a movable rod 404, which can limit and guide the movement of the movable rod 404, improving the stability when the threaded rod 403 drives the movable rod 404, which is fitted with a threaded cylinder 405, to move up and down. A base 7 is fixedly connected to the bottom of the support column 401. Grooves are provided on both sides of the bottom of the base 7, and an electric push rod 8 is fixedly connected to the top of the inner cavity of the groove. A movable wheel 9 is fixedly connected to the telescopic end of the electric push rod 8. 8. The moving wheels 9 are pushed downwards to contact the ground, making it easy for the user to move the device. A battery box 10 is fixedly connected to the top of the base 7. A battery is fixedly connected to the inner cavity of the battery box 10, which can provide power to the device and expand its range of use. An alarm 11 is fixedly connected to the top of the two protective boxes 301. When an intrusion occurs, the alarm 11 will sound an alarm to remind on-site personnel to check, which improves the flexibility of the guard. A controller 12 is fixedly connected to the opposite side of the two protective boxes 301. The controller 12 is equipped with a display screen and control buttons, which can facilitate the user to control the device.

[0031] The principle of this embodiment is as follows:

[0032] In use, the device is controlled by the controller 12. Activating the electric push rod 8 pushes the moving wheel 9 downwards to contact the ground, allowing the user to easily move the device. The infrared transmitter 1 and infrared receiver 2 can then be placed separately. After they are moved to their respective destinations, the moving wheel 9 is retracted into the base 7 to increase the stability of the device. Then, the first motor 302 is activated to rotate the protective plate 303, opening the protective box 301 for easy access to the infrared transmitter 1 and infrared receiver 2. Finally, depending on the terrain, the second motor 402 is activated to rotate the protective plate 303. The threaded rod 403 rotates, causing the movable rod 404, which is fitted with the threaded cylinder 405, to move upward. At this time, the height of the infrared transmitter 1 and the infrared receiver 2 can be adjusted to be at the same level. Then, the infrared transmitter 1 and the infrared receiver 2 are turned on, which can achieve infrared surveillance of 50-100 meters. When the infrared receiver 2 cannot receive the infrared light emitted by the infrared transmitter 1, an intrusion has occurred. At this time, the alarm 11 will sound an alarm to remind the on-site personnel to check, thus improving the flexibility of the surveillance.

[0033] In summary, this infrared anti-intrusion device, by setting up an infrared transmitter 1 and an infrared receiver 2, can achieve infrared surveillance at a range of 50-100 meters. The protective component 3 protects the infrared transmitter 1 and infrared receiver 2 from direct exposure and prevents damage from impacts by external hard objects. The lifting component 4 allows the user to easily adjust the height of the infrared transmitter 1 and infrared receiver 2, improving the flexibility of the surveillance.
