Description

Technical Field

[0001] This utility model relates to the field of security inspection equipment technology, specifically an alarm device for intercepting unfamiliar personnel from entering. Background Technology

[0002] Given the growing demand for social security and protection, various venues are increasingly tightening their controls on the entry of strangers.

[0003] Traditional interception methods mainly rely on manual guarding or fixed barriers and access control facilities. Manual guarding suffers from high labor costs, susceptibility to fatigue and subjective judgment, making it difficult to achieve precise 24 / 7 control. Fixed barriers and access control facilities lack flexibility and are not convenient to adjust quickly according to actual traffic needs. In emergencies, they cannot respond promptly and effectively intercept unfamiliar intruders. Furthermore, while some existing automatic interception devices have certain automation functions, they mostly use rigid structures, which are easily damaged when subjected to external impacts, and lack real-time monitoring and alarm linkage mechanisms for intrusion behavior.

[0004] Therefore, there is an urgent need for a device that can automatically and quickly respond, flexibly adjust the interception status, and also has real-time monitoring and alarm functions to solve the shortcomings of existing technologies in the interception and control of unfamiliar personnel.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 7 This utility model embodiment provides an alarm interception device, which is applied to scenarios where strangers are prevented from entering. This embodiment improves the structure of the alarm interception device to give it the advantages of rapid blocking and good interception capabilities. Specifically, taking the timely prevention of strangers from entering as an example, as a preferred solution in this embodiment, the alarm interception device is specifically an alarm device for intercepting the entry of strangers, capable of blocking passageways.

[0029] Please see Figures 1 to 7This utility model provides a technical solution: an alarm device for blocking strangers from entering, which is mainly used in scenarios where strangers are blocked from entering.

[0030] It includes a support mechanism 2 and multiple blocking mechanisms 4, wherein:

[0031] The support mechanism 2 includes two support columns 201, two guide grooves 205 and two threaded rods 206. The two guide grooves 205 are respectively opened on the adjacent outer surfaces of the two support columns 201, and the two threaded rods 206 are respectively rotatably connected to the inner sidewalls of the two guide grooves 205.

[0032] The blocking mechanism 4 includes two guide blocks 401, two threaded sleeves 402, two tension springs 403, and a blocking cable 404. The two guide blocks 401 are slidably connected to the inner walls of the two guide grooves 205. The two threaded sleeves 402 are rotatably connected to the inner walls of the guide blocks 401 through damping bearings. One end of each of the two tension springs 403 is fixedly connected to the outer walls of the two guide blocks 401, and the other end of each tension spring 403 is fixedly connected to both ends of the blocking cable 404.

[0033] In this embodiment, the support column 201 serves as the basic support component of the entire device, used to fix and install other components, such as the guide groove 205, threaded rod 206, and detection sensor 204, providing stable structural support for the device and ensuring the overall stability and reliability of the device. The guide groove 205 is formed on the adjacent outer surface of the support column 201, providing guidance for the sliding of the guide block 401, allowing the guide block 401 to slide up and down on the support column 201 along a predetermined direction, thereby realizing the adjustment of the height position of the arresting cable 404. The threaded rod 206... The guide block 401 is rotatably connected to the inner wall of the guide groove 205. Through its threaded engagement with the threaded sleeve 402, it rotates under the drive of the motor 203, causing the threaded sleeve 402 and guide block 401 to move up and down along the guide groove 205, thereby controlling the raising and lowering of the barrier cable 404 to block and allow passage. The guide block 401 is slidably connected to the inner wall of the guide groove 205. Through the engagement of the threaded sleeve 402 and the threaded rod 206, it moves up and down along the guide groove 205 when the threaded rod 206 rotates, thus raising and lowering the barrier cable 404. This is a practical... The key component for adjusting the position of the arresting cable 404 is the threaded sleeve 402, which is rotatably connected to the inner wall of the guide block 401 via a damping bearing. It engages with the threaded rod 206, converting the rotation of the threaded rod 206 into the linear motion of the guide block 401. Simultaneously, the damping bearing allows the threaded sleeve 402 to idle within the guide block 401 after the limiting block 503 is engaged in the limiting groove 6, until the motor 203 reverses, causing the threaded sleeve 402 to move in the opposite direction. This allows multiple guide blocks 401 to achieve an arresting effect at different heights. The tension spring 4... One end of the 03 is fixedly connected to the outer wall of the guide block 401, and the other end is fixedly connected to both ends of the barrier cable 404, which provides an elastic connection between the two ends of the barrier cable 404. When the barrier cable 404 is impacted by an external force, the elastic force of the tension spring 403 can absorb and buffer the impact force, reduce the damage to the barrier cable 404, and ensure the interception effect. The barrier cable 404 is used to block the passage space within the two support columns 201. When the guide block 401 drives it to descend, it can block the passage space in time and play the role of intercepting strangers.

[0034] In the above embodiment, as a preferred option, a fixing mechanism 1 is fixedly installed at the bottom of the two support columns 201. The fixing mechanism 1 includes a fixing seat 101 and a protective pad 102. The two sides of the top of the fixing seat 101 are fixedly connected to the bottom of the support column 201, and the protective pad 102 is laid and fixed in the middle of the top of the fixing seat 101. The two sides of the top of the fixing seat 101 are fixedly connected to the bottom of the support column 201. This is used to fix the entire device on the ground or other foundation structure, ensuring the stability of the device during use and preventing it from moving or tipping over due to external forces. The protective pad 102, laid and fixed in the middle of the top of the fixing seat 101, can increase the friction between the fixing seat 101 and the foundation structure, further improving the stability of the device. At the same time, it plays a role in buffering and shock absorption to a certain extent, reducing the damage of the device to the foundation structure.

[0035] In the above embodiment, as a preferred option, the support mechanism 2 further includes a crossbeam 202, two motors 203, and four detection sensors 204. The bottom sides of the crossbeam 202 are fixedly installed to the tops of the two support columns 201. The two motors 203 are fixedly installed to the top sides of the crossbeam 202, and their output ends are connected to the tops of the two threaded rods 206 via key transmission. The four detection sensors 204 are fixedly installed on the outer walls of the two support columns 201 and located on both sides of the two guide grooves 205. The bottom sides of the crossbeam 202 are fixedly installed to the tops of the support columns 201, serving to connect the two support columns 201 and enhance the overall rigidity and stability of the device. The system provides a platform for the installation of components such as the motor 203 and the alarm mechanism 3. The motor 203 is fixedly installed on both sides of the top of the crossbeam 202, and its output end is connected to the top of the threaded rod 206 via a key drive, providing power for the rotation of the threaded rod 206, thereby realizing the automatic raising and lowering of the barrier cable 404, improving the automation level of the device, and enabling a rapid response to the situation of strangers entering. The detection sensor 204 is fixedly installed on the outer wall of the support column 201 and located on both sides of the guide groove 205, for real-time monitoring of people entering the passage space. When an abnormal person is detected, it can promptly transmit a signal to the control system, triggering the alarm mechanism 3 and the lowering of the barrier cable 404 to intercept strangers.

[0036] In the above embodiment, as a preferred option, an alarm mechanism 3 is provided on the top of the crossbeam 202. The alarm mechanism 3 includes a mounting base 301, a support rod 302, and an alarm light 303. Two mounting bases 301 are threadedly connected to the top of the crossbeam 202, one end of each of the two support rods 302 is fixedly mounted on the top of the two mounting bases 301, and two alarm lights 303 are fixedly mounted on the top of the two support rods 302. The mounting base 301 is threadedly connected to the top of the crossbeam 202 to fix the support rods 302, providing a mounting base for the alarm mechanism 3, enabling the alarm mechanism 3 to... The support rod 302 is stably installed on the device. One end of the support rod 302 is fixedly installed on the top of the mounting base 301, and the other end is fixedly installed on the alarm light 303. It serves to support and connect the alarm light 303, raising the alarm light 303 to a certain height so that it can more effectively emit an alarm signal and attract the attention of people in the vicinity. The alarm light 303 is fixedly installed on the top of the support rod 302. When the detection sensor 204 detects the entry of an unfamiliar person, the alarm light 303 is triggered and illuminates, emitting a strong visual alarm signal to remind relevant personnel that an unfamiliar person has entered, so that appropriate measures can be taken in time.

[0037] In the above embodiment, as a preferred option, the inner walls of the two guide grooves 205 are provided with multiple limiting mechanisms 5. Each limiting mechanism 5 includes a sliding groove 501, a compression spring 502, and a limiting block 503. The sliding groove 501 is formed in the inner wall of the guide groove 205. One end of the compression spring 502 is fixedly connected to the inner bottom wall of the sliding groove 501. The outer surface of the limiting block 503 is slidably connected to the inner wall of the sliding groove 501. One end of the limiting block 503 is fixedly connected to the other end of the compression spring 502. The sliding groove 501, formed in the inner wall of the guide groove 205, provides space for the sliding of the limiting block 503, allowing the limiting block 503 to... The guide block 401 moves along the guide groove 205 within the slide groove 501. Simultaneously, the arc angle of the lower edge of the guide block 401 can push the limiting block 503, causing the limiting block 503 to retract into the slide groove 501. This prevents the sliding of the guide block 401 from being affected. After the guide block 401 moves to the appropriate position, the limiting block 503 is inserted into the limiting groove 6 by means of the spring force of the compression spring 502, preventing the guide block 401 from continuing to slide down after reaching the appropriate position. The inclined limiting block 503 and the inclined limiting groove 6 can move the guide block 401 back to the top when it slides upward.

[0038] In the above embodiment, as a preferred solution, a limiting groove 6 is formed on the side of the outer surface of the two guide blocks 401 away from the tension spring 403. The inner sidewall of the limiting groove 6 is engaged with the outer surface of the limiting block 503. The limiting groove 6 is formed on the side of the outer surface of the guide block 401 away from the tension spring 403 and is engaged with the outer surface of the limiting block 503. Together with the limiting mechanism 5, the position of the guide block 401 is limited, thereby ensuring that the blocking cable 404 performs interception and release operations at a suitable height position.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] In this invention, the working steps of the device are as follows:

[0041] 1. The entire device is fixed to the ground or other foundation structure by anchor bolts to fix the fixing seat 101 of the fixing mechanism 1. The protective pad 102 increases the friction to prevent people from slipping and ensures the stability of the device.

[0042] 2. Initial state setting: When the device is initially set up, the blocking cable 404 is in the retracted state, the guide block 401 is located in a suitable position above the guide groove 205, the threaded sleeve 402 is engaged with the threaded rod 206, but the blocking cable 404 is not lowered.

[0043] 3. Personnel monitoring: The detection sensor 204 monitors the entry of personnel in the passage space in real time. When abnormal or unfamiliar personnel are detected, the signal is transmitted to the control system.

[0044] 4. Blocking Operation: After receiving the signal from the detection sensor 204, the control system triggers the motor 203 to start. The output of the motor 203 drives the threaded rod 206 to rotate via a key drive. The threaded sleeve 402 rotates on the threaded rod 206 and drives the guide block 401 to slide downward along the guide groove 205. As the guide block 401 slides down, it causes the blocking cable 404 to descend, blocking the passage space within the two support columns 201 and thus intercepting unfamiliar personnel. During this process, the arc angle of the lower edge of the guide block 401 pushes the limiting block 503 into the slide groove 501, which does not affect the downward movement of the guide block 401.

[0045] 5. Alarm issued: When the detection sensor 204 detects an unfamiliar person entering, it simultaneously triggers the alarm light 303 of the alarm mechanism 3 to light up, emitting a strong visual alarm signal to remind the surrounding personnel that an unfamiliar person has broken in.

[0046] 6. External force buffer: If the arresting cable 404 is subjected to an external force impact, the elastic force of the tension spring 403 absorbs and buffers the impact force, reducing damage to the arresting cable 404 and ensuring the interception effect.

[0047] 7. Release the block: When it is necessary to release the block, the motor 203 reverses and drives the threaded rod 206 to rotate in the opposite direction. The threaded sleeve 402 drives the guide block 401 to slide upward along the guide groove 205. During the upward sliding of the guide block 401, the inclined limit block 503 and the limit groove 6 cooperate to move the guide block 401 back to the top. Under the action of the compression spring 502, the limit block 503 is locked into the limit groove 6 again, and the blocking cable 404 is retracted.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
