Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of safety protection, and specifically, to a personnel intrusion protection device for an operation area based on multi-sensor linkage. Background Art

[0002] In various industrial production, construction, power facility maintenance and other operation areas, ensuring personnel safety is of crucial importance. Traditionally, in order to demarcate the operation area and prevent unauthorized personnel from entering, ordinary guardrails are often used. However, ordinary guardrails have obvious deficiencies in practical applications, especially the lack of an effective warning function.

[0003] Most ordinary guardrails only prevent personnel from entering the operation area through simple physical barriers. Their structures are usually relatively simple, relying solely on the blocking effect of the fence itself. In a dimly lit environment, such as a night construction site or an underground operation area, it is difficult for ordinary guardrails to be clearly identified by personnel in the distance, which may allow unauthorized personnel to approach or even enter the operation area without being aware, increasing the risk of safety accidents.

[0004] In addition, ordinary guardrails do not have an active warning function. When someone approaches or attempts to climb over the guardrail, it cannot issue an alarm in time to alert the operating personnel and the intruder, resulting in the inability to take measures to prevent the intrusion behavior immediately, thus exposing the personnel and equipment in the operation area to danger. For example, in a high-voltage electricity operation area, if someone accidentally enters, the ordinary guardrail cannot give a timely reminder, which may cause serious electric shock accidents.

[0005] Moreover, ordinary guardrails cannot be integrated with modern safety management systems. With the development of technology, safety management increasingly relies on intelligent means to achieve real-time monitoring and early warning through multi-sensor linkage. However, due to their single function, ordinary guardrails are difficult to connect to various sensors and cannot work in coordination with other safety devices, failing to meet the requirements of modern safety management.

[0006] With the continuous improvement of the awareness of work safety and the increasingly strict safety management requirements, it is urgent to develop a personnel intrusion protection device for an operation area that has a warning function and can be linked with multi-sensors. This can not only effectively prevent unauthorized personnel from entering the operation area, ensure the safety of personnel and equipment, but also improve the intelligent level of safety management and reduce the occurrence of safety accidents. Utility Model Content

[0007] To overcome the above defects, embodiments of the present disclosure provide a personnel intrusion protection device for an operation area based on multi-sensor linkage, solving the technical problem that most ordinary guardrails in the prior art only prevent personnel from entering the operation area through simple physical barriers, and their structures are usually relatively simple, relying solely on the blocking effect of the fence itself.

Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] like Figures 1-5 As shown, it illustrates a multi-sensor linkage-based personnel intrusion protection device for work areas according to an embodiment of this disclosure, including:

[0038] The main frame 1, the working equipment 8, a pair of connecting frames 2 and a pair of side frames 3 are provided. The connecting frames 2 are rotatably connected to the outer surface of the main frame 1 by pins, and the side frames 3 are fixed to both sides of the main frame 1 by bolts.

[0039] Side protection component 5, which is disposed on the side frame 3;

[0040] Main protective component 4, which is disposed on the main frame 1 and the connecting frame 2;

[0041] The main protective component 4 includes several distance sensors 4-1, all of which are mounted on the surface of the main frame 1. Several movable columns 4-2 are movably connected inside the connecting frame 2. One end of each movable column 4-2 is provided with an outer protective railing 4-3. A first spring 4-4 ​​is installed on each of the movable columns 4-2 located at the top and bottom. LED light panels 4-5 are provided at both ends of the surface of the main frame 1. A pair of rectangular openings 4-6 are provided on the surface of the main frame 1. Vibration sensors 4-7 are installed in each of the rectangular openings 4-6. Sleeves 4-8 are provided at both the top and bottom ends of the outer surface of the connecting frame 2. Pressure sensors 4-9 are provided on the inner side of the sleeves 4-8. The output end of the pressure sensor 4-9 is attached to the surface of the corresponding movable column 4-2. Several electric push rods 4-10 are provided on the inner surface of one side of the connecting frame 2. A fixing rod 4-11 is provided at the output end of each electric push rod 4-10. One end of the fixing rod 4-11 is inserted into the surface of another connecting frame 2.

[0042] In some examples, during the process of preventing personnel from entering the work area, a main protective component 4 is designed to achieve flexible control over personnel entry and exit and effective monitoring and protection against intrusion. This component includes several distance sensors 4-1 installed on the surface of the main frame 1 to monitor the approach of personnel in front of the work area in real time. When personnel are detected approaching, an early warning signal can be issued in time. Several movable columns 4-2 mounted inside the connecting frame 2 and an outer protective railing 4-3 set at one end constitute a movable protective barrier. The first springs 4-4 mounted on the movable columns 4-2 at the top and bottom provide elastic support for the outer protective railing 4-3, so that it maintains a normal protective state when not subjected to external force. LED light panels 4-5 set at both ends of the surface of the main frame 1 can light up when an abnormality is detected, or can remain lit to display warning information, serving as a warning. In addition to its warning function, the vibration sensor 4-7 installed inside the rectangular opening 4-6 on the surface can detect vibrations caused by personnel intrusion or other external forces, further improving the accuracy of monitoring. The pressure sensor 4-9 inside the sleeve 4-8 set at both ends of the outer surface of the connecting frame 2 has its output end attached to the surface of the movable column 4-2, which can detect the pressure change on the movable column 4-2, thereby determining whether the outer protective railing 4-3 has been touched or moved. When normal personnel access is required, the electric push rod 4-10 set inside one side of the connecting frame 2 is activated, and the fixed rod 4-11 at the output end of the electric push rod 4-10 is pulled out from the surface of the other connecting frame 2. At this time, the connecting frame 2 can rotate around the pin, driving the outer protective railing 4-3 to open, facilitating personnel entry and exit. After personnel pass through, the electric push rod 4-10 is activated again to insert the fixed rod 4-11, closing the outer protective railing 4-3 and restoring the protective state.

[0043] Through the coordinated operation of components such as distance sensor 4-1, movable column 4-2, outer guardrail 4-3, first spring 4-4, LED light panel 4-5, vibration sensor 4-7, sleeve 4-8, pressure sensor 4-9, electric push rod 4-10, and fixed rod 4-11, the main protective assembly 4 realizes the switchable function of the connecting frame 2 and the outer guardrail 4-3, which can both ensure normal personnel access and effectively protect the work area.

[0044] like Figures 1-5 As shown in the figure, the side protection component 5 in this embodiment includes a side guardrail 5-1, which is fixed to the side surface of the side frame 3. The side guardrail 5-1 has a plurality of buffer posts 5-2 on its surface. A side enclosure 5-3 is fitted onto one side of the side guardrail 5-1. The side enclosure 5-3 has a plurality of round holes 5-4 on its surface. The round holes 5-4 are fitted onto the outside of the buffer posts 5-2. A second spring 5-5 is provided between the buffer posts 5-2 and the surface of the side enclosure 5-3.

[0045] In some examples, in the work area personnel protection work, in order to expand the protection range and enhance the protection capability of the surrounding area, a side protection component 5 is designed. This component includes a side guardrail 5-1 fixed to the side surface of the side frame 3 as a basic protection structure. Several buffer posts 5-2 are set on the surface of the side guardrail 5-1, which cooperate with the round holes 5-4 opened on the side enclosure 5-3 fitted on one side of the side guardrail 5-1. The side enclosure 5-3 can slide on the buffer posts 5-2. A second spring 5-5 is set between the surface of the buffer posts 5-2 and the side enclosure 5-3 to provide elastic force for the side enclosure 5-3. When it is necessary to increase the protection range, the side enclosure 5-3 can be pulled outward. The side enclosure 5-3 slides on the buffer posts 5-2 and stretches the second spring 5-5, so that the side protection area extends outward, thereby expanding the coverage of the entire protection device. When subjected to external impact, the second spring 5-5 can play a buffering role, reducing the impact force on the side guardrail 5-1, and can transmit vibration, in conjunction with the vibration sensor 4-7.

[0046] Through the coordinated operation of components such as side guardrail 5-1, buffer post 5-2, side enclosure 5-3, round hole 5-4, and second spring 5-5, the side protection assembly 5 can extend to the surrounding area, effectively increasing the protection range and improving the protection effect on the perimeter of the work area.

[0047] For example, such as Figure 1 As shown, a flashing buzzer 6 is provided on the top of the side guardrail 5-1.

[0048] In some examples, a flashing buzzer 6 or continuously flashing lights can be used to issue a warning, making it more conspicuous and improving the warning effect.

[0049] For example, such as Figure 2 As shown, a controller 7 is provided on the surface of the main frame 1, and a pair of infrared sensors 9 are provided on the surface of each of the outer protective railings 4-3.

[0050] In some examples, the controller 7 is used to control various sensors and accessories such as electric push rods 4-10, and the infrared sensor 9 is used to detect people.

[0051] In actual use: The protective device is placed at the entrance of the working equipment 8, and the entire device is lower than the feeding height. When the infrared sensor 9 senses the approach of a person, the flashing buzzer 6 will sound an alarm. The side frame 3 is fixed to both sides of the main frame 1 with bolts. In the initial state, the connecting frame 2 is locked by the electric push rod 4-10 and the fixing rod 4-11. The outer protective barrier 4-3 is in the closed state. The distance sensor 4-1 monitors the approach of personnel in real time. When someone approaches, the LED light panel 4-5 lights up as a warning. If a person touches the outer protective barrier 4-3, the vibration sensor 4-7 and the pressure sensor 4-9 sense and transmit signals. The controller 7 controls the flashing buzzer 6 to flash. If the person enters and exits normally, the electric push rod 4-10 is activated to pull out the fixing rod 4-11, and the connecting frame 2 is rotated to open the outer protective barrier 4-3. After passing through, it is closed again.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure 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 disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
