Description

Technical Field

[0001] This invention relates to the field of intelligent safety fence technology, and in particular to an intelligent early warning safety fence. Background Technology

[0002] Intelligent early warning security fences are a key technology in the field of modern perimeter security. They mainly consist of poles and monitoring and early warning devices integrated on the top of the poles, such as lidar or millimeter-wave radar. The system actively transmits and receives detection signals to achieve non-contact and large-scale real-time monitoring and early warning of intrusion behavior in specific areas. It is widely used in industrial parks, important infrastructure and construction sites, effectively improving the initiative and coverage efficiency of security protection.

[0003] The core of this intelligent early warning security fence lies in whether the monitoring device can be aligned with and cover the correct warning area. The accuracy and convenience of its installation and debugging directly determine the final effectiveness of the entire security system. However, many existing fences have simple structures, with a fixed rigid connection between the monitoring and early warning device and the pole. They must be used with standardized poles and do not have tilt angle adjustment. This design results in extremely poor installation adaptability. If the ground where the pole is installed has a slope, or if monitoring is required for areas at different distances and heights, the angle of the monitoring device cannot be adjusted to fit. Instead, adjustments can only be made using non-standard methods such as adding shims, or by replacing the pole with a different specification, or even relocating the installation site. This not only greatly increases the difficulty and cost of installation and debugging, but also severely limits the application range of the same specification fence in different terrain environments. Insufficient flexibility is its significant drawback. Therefore, this application provides an intelligent early warning security fence to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an intelligent early warning safety fence to solve the problems that existing intelligent early warning safety fences cannot adapt to different specifications of poles and have a small range of applications after installation.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A smart early warning safety fence includes a smart safety fence body, a solar panel at the top, a joint seat and an outer tube at the bottom, connected by a joint ball, symmetrically distributed fixing plates inside the outer tube, and an adjustment component that drives the fixing plates to move within the outer tube, a push-pull rod outside the outer tube, and a lifting component associated with the push-pull rod at the top of the outer tube, a locking component at the bottom of the joint seat, and a corrugated pipe fixedly connected to the joint seat and the outer tube, fitted outside the locking component; the adjustment component drives the displacement of the fixing plates and is connected to the outer tube; the locking component fixes the relative position between the joint ball and the joint seat and is connected to the joint seat; the lifting component drives the locking component and is connected to the push-pull rod.

[0007] Optionally, the adjustment assembly includes a bidirectional screw rotatably connected to the outer sleeve via a bearing. The outer side of the bidirectional screw is provided with symmetrically distributed threads in opposite directions, and one end of the bidirectional screw extends to the outside of the outer sleeve and is fixedly connected to a knob.

[0008] Optionally, the outer sleeve has guide rods symmetrically distributed on both sides of the bidirectional screw fixedly connected, and the top of the fixed plate has a connecting plate fixedly connected. The connecting plate is threadedly connected to the bidirectional screw, and the connecting plate is slidably sleeved on the outside of the guide rods.

[0009] Optionally, the outer sleeve and the joint seat are movably connected by a joint ball. The joint seat has a spherical groove that matches the shape of the joint ball. The bottom of the joint ball is fixedly connected to the top of the outer sleeve by a connecting rod. The part of the joint ball connected to the connecting rod is located outside the joint seat.

[0010] Optionally, the locking assembly includes a locking sleeve fitted onto the bottom of the joint seat, with a top limiting end fixedly connected to the top end of the locking sleeve and a bottom limiting end fixedly connected to the bottom end of the locking sleeve, and a movable cavity provided at the bottom of the joint seat that matches the shape of the locking sleeve and the top limiting end.

[0011] Optionally, the top limiting end is sleeved in the movable cavity, and the bottom of the top limiting end is fixedly connected to the joint seat with uniformly distributed elastic plates. The elastic plates have a wavy plate structure, and the locking sleeve has a through offset area in the middle.

[0012] Optionally, the lifting assembly includes a movable frame fixedly connected to one end of a push-pull rod extending into the inner part of the outer sleeve, with a pressure plate fixedly connected to the top of the movable frame, and the movable frame slidably sleeved on the outside of the guide rod.

[0013] Optionally, the bottom of the movable frame is provided with a clearance groove corresponding to the position of the bidirectional screw, and a spring is fixedly connected between the movable frame and the connecting plate away from the knob. The other end of the push-pull rod is located outside the outer tube and is rotatably fixedly connected to a push-pull head through a rotating rod. The push-pull head is located above the knob, and a protrusion is provided on the outside of the push-pull head. The knob is provided with evenly distributed grooves that match the shape of the protrusion on the side near the outer tube.

[0014] Optionally, the inner sleeve of the outer sleeve is fitted with a lifting plate located above the movable frame and the pressure plate. The bottom of the lifting plate is fixedly connected with a pressure block that matches the shape of the pressure plate, and the top of the lifting plate is fixedly connected with evenly distributed pressure rods.

[0015] Optionally, the top of the outer sleeve has a through hole that matches the shape of the pressure rod. The pressure rod passes through the through hole, and a limit plate is fixedly connected to the top of the pressure rod. The entire pressure rod is made of hard rubber.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting an adjustment assembly consisting of a bidirectional screw, a guide rod, and a fixing plate, the fence body can be quickly adapted to and firmly clamped to the top of uprights of different sizes through simple knob operation, which greatly expands the applicability of the equipment and simplifies the installation and fixing process.

[0018] The design of the joint ball, joint seat and locking component allows the pitch monitoring angle of the fence body to be flexibly adjusted according to actual needs, expanding the monitoring area. After adjustment, the lifting component drives the locking component to effectively squeeze and lock the joint ball, ensuring the stability of the adjusted angle, thereby ensuring the reliability and continuity of the monitoring area.

[0019] The lifting, adjusting, and locking components work together in a clever way. The push-pull rod, movable frame, and pressure plate not only achieve the locking function, but the push-pull head and knob on them can also assist in limiting the adjustment knob in the locked state through the cooperation of protrusions and grooves. This effectively prevents loosening caused by accidental touch and enhances the stability of the overall structure and the integration of operation.

[0020] By integrating solar panels on the top of the fence body, solar energy can be converted into electrical energy and stored in batteries to continuously power early warning units such as lidar, millimeter-wave radar, and buzzer alarms. This significantly improves the equipment's endurance in environments without mains power supply, meeting the needs of long-term outdoor deployment. Attached Figure Description

[0040] like Figures 1 to 3 As shown, an embodiment of the present invention provides an intelligent early warning safety fence, including an intelligent safety fence body 1. A solar panel 2 is disposed at the top of the intelligent safety fence body 1, and a joint seat 3 and an outer sleeve 4 are assembled at the bottom of the intelligent safety fence body 1. The joint seat 3 and the outer sleeve 4 are connected by a joint ball 10. A symmetrically distributed fixing plate 7 is fitted inside the outer sleeve 4, and an adjustment component capable of driving the fixing plate 7 to move is disposed within the outer sleeve 4. A push-pull rod 9 is fitted outside the outer sleeve 4, and a lifting component associated with the push-pull rod 9 is fitted at the top of the outer sleeve 4. A locking component capable of locking the joint ball 10 is fitted at the bottom of the joint seat 3. A locking component fitted on the joint seat 3 and the outer sleeve 4 is fixedly connected between the joint seat 3 and the outer sleeve 4. The corrugated pipe 5 outside the tight component, the intelligent safety fence body 1 is equipped with a lidar and millimeter-wave radar as well as a battery. The battery powers the lidar and millimeter-wave radar. A buzzer alarm is installed at the bottom of the intelligent safety fence body 1. When the lidar or millimeter-wave radar detects personnel entering the monitoring area, it will sound an alarm to warn of the situation. The solar panel 2 on the top of the intelligent safety fence body 1 can convert solar energy into electrical energy and store it in the battery when there is good sunlight, thereby greatly improving the endurance of the entire intelligent early warning safety fence. The principles and usage of the lidar, millimeter-wave radar, buzzer alarm and solar panel 2 are the same as those of the existing technology, and will not be described in detail here.

[0041] The adjusting component in the outer sleeve 4 can adjust the position of the fixing plate 7 in the outer sleeve 4, thereby adjusting the distance between the two fixing plates 7. When installing and fixing the intelligent early warning safety fence using poles of different specifications, the outer sleeve 4 can be fitted onto the top of the pole, and the distance between the fixing plates 7 can be adjusted by the adjusting component, so that the fixing plates 7 clamp the top of the pole, realizing the installation and fixing of the intelligent safety fence body 1 at the top of the pole. The connection between the joint seat 3 and the outer sleeve 4 through the joint ball 10 allows the angle between the intelligent safety fence body 1 and the outer sleeve 4 to be adjusted by the deflection between the joint seat 3 and the joint ball 10, thereby greatly expanding the monitoring area of ​​the intelligent safety fence body 1 and allowing the monitoring area of ​​the intelligent safety fence body 1 to be flexibly adjusted according to actual usage needs. After the pitch angle of the intelligent safety fence body 1 is adjusted, the lifting component and the locking component can cooperate to lock the relative positions of the joint seat 3, the outer sleeve 4 and the joint ball 10, thereby ensuring the stability of the intelligent safety fence body 1 after the pitch angle is adjusted, and ensuring the stability and reliability of the monitoring area of ​​the intelligent safety fence body 1.

[0042] In this embodiment, as Figure 2 , Figure 3 and Figure 9 As shown, the adjusting assembly includes a bidirectional screw 8 rotatably connected to the outer sleeve 4 via a bearing. The outer side of the bidirectional screw 8 is provided with symmetrically distributed threads in opposite directions. One end of the bidirectional screw 8 extends to the outside of the outer sleeve 4 and is fixedly connected to a knob 6. Guide rods 29 symmetrically distributed on both sides of the bidirectional screw 8 are fixedly connected to the outer sleeve 4. A connecting plate 28 is fixedly connected to the top of the fixing plate 7. The connecting plate 28 is threadedly connected to the bidirectional screw 8, and the connecting plate 28 is slidably sleeved on the outside of the guide rods 29. Thus, rotating the knob 6 from the outside of the outer sleeve 4 drives the bidirectional screw 8 to rotate, thereby adjusting the upper part of the bidirectional screw 8. The threaded portion pushes the connecting plate 28 to slide along the guide rod 29 in the outer sleeve 4. Then, the connecting plate 28 drives the fixing plate 7 to move in the outer sleeve 4. When the top of the pole is fitted between the fixing plates 7, adjusting the displacement of the fixing plate 7 to clamp it outside the top of the pole can fix the relative position between the outer sleeve 4 and the fixing plate 7 and the top of the pole. This achieves the overall installation and fixation of the intelligent safety fence body 1, making the installation and fixation operation between the intelligent safety fence body 1 and the pole simple and convenient, and can adapt to poles of different sizes and specifications, greatly improving the overall adaptability of the intelligent early warning safety fence.

[0043] In this embodiment, as Figures 3 to 7As shown, the outer sleeve 4 and the joint seat 3 are movably connected by a joint ball 10. A spherical groove adapted to the shape of the joint ball 10 is formed in the joint seat 3. Most of the joint ball 10 is fitted into this groove. The bottom of the joint ball 10 is fixedly connected to the top of the outer sleeve 4 via a connecting rod. The portion of the joint ball 10 connected to the connecting rod is located outside the joint seat 3. The connection between the joint seat 3 and the outer sleeve 4 via the joint ball 10 allows the angle between the intelligent safety fence body 1 and the outer sleeve 4 to be adjusted by the deflection between the joint seat 3 and the joint ball 10, thus expanding the monitorable area of ​​the intelligent safety fence body 1. The monitoring area of ​​the intelligent safety fence body 1 can be flexibly adjusted according to actual usage needs. The locking component includes a locking sleeve 11 fitted onto the bottom of the joint seat 3. A top limiting end 19 is fixedly connected to the top of the locking sleeve 11, and a bottom limiting end 21 is fixedly connected to the bottom of the locking sleeve 11. The bottom of the joint seat 3 has a movable cavity 17 that matches the shape of the locking sleeve 11 and the top limiting end 19. The top limiting end 19 is fitted into the movable cavity 17, and uniformly distributed elastic sheets 20 are fixedly connected between the bottom of the top limiting end 19 and the joint seat 3. The elastic sheets 20 have a wavy sheet structure. A through offset area 23 is opened in the middle of the locking sleeve 11. The diameter of the offset area 23 is larger than the cross-sectional diameter of the connecting rod that is fixedly connected between the joint ball 10 and the outer sleeve 4. This ensures that when the intelligent safety fence body 1 is adjusted in pitch angle, the locking sleeve 11 will not interfere with the relative displacement between the joint seat 3 and the joint ball 10. A locking seat 22 is fixedly connected to the top position of the offset area 23 in the locking sleeve 11. The locking seat 22 is made of hard rubber. After being squeezed and pressed against the outside of the joint ball 10 by external force, it can generate a certain deformation through its own rubber material, increasing the friction between it and the outer surface of the joint ball 10, thereby achieving the squeezing and locking effect on the joint ball 10. When the intelligent safety fence body 1 is tilted in pitch angle, the locking seat 22 will not interfere with the relative displacement between the joint seat 3 and the joint ball 10. After the pitch angle is adjusted, the lifting component can apply an upward squeezing force to the bottom limiting end 21 of the locking sleeve 11, thereby causing the locking sleeve 11 and the top limiting end 19 to slide and stretch the elastic sheet 20 in the movable cavity 17. While the elastic sheet 20 is stretched, it deforms and accumulates elastic potential energy. At the same time, the locking seat 22 in the locking sleeve 11 follows the displacement of the locking sleeve 11 and comes into contact with the area of ​​the joint ball 10 outside the joint seat 3, forming a lock on the joint ball 10. This ensures that the pitch angle of the intelligent safety fence body 1 can be fixed and stable after adjustment, thereby ensuring the stability of the monitoring area under the working state of the intelligent safety fence body 1.

[0044] In this embodiment, as Figures 3 to 10As shown, the lifting assembly includes a movable frame 15 fixedly connected to one end of a push-pull rod 9 extending into the inner wall of the outer sleeve 4. A pressure plate 16 is fixedly connected to the top of the movable frame 15, and the movable frame 15 is slidably sleeved on the outside of the guide rod 29. An angle is provided between the pressure plate 16 and the movable frame 15, and the pressure plate 16 is inclined towards the inner wall of the outer sleeve 4. A clearance groove corresponding to the position of the bidirectional screw 8 is provided at the bottom of the movable frame 15, and a spring 24 is fixedly connected between the movable frame 15 and the connecting plate 28 away from the knob 6. The other end of the push-pull rod 9 is located outside the outer sleeve 4 and is rotatably fixedly connected to a push-pull head 25 via a rotating rod. The push-pull head 25 is located above the knob 6, and a protrusion 26 is provided on the outside of the push-pull head 25. The knob 6 is close to One side of the outer sleeve 4 has evenly distributed grooves 30 that match the shape of the protrusions 26. Inside the outer sleeve 4, a lifting plate 12 is fitted above the movable frame 15 and the pressure plate 16. The bottom of the lifting plate 12 is fixedly connected to a pressure block 14 that matches the shape of the pressure plate 16, and the top of the lifting plate 12 is fixedly connected to evenly distributed pressure rods 13. The top of the outer sleeve 4 has a through hole 18 that matches the shape of the pressure rod 13. The pressure rod 13 passes through the through hole 18, and the top of the pressure rod 13 is fixedly connected to a limiting plate 27. The pressure rod 13 is made entirely of hard rubber, possessing a certain deformation capacity while also providing good support. During operation, after completing the fixing operation between the outer sleeve 4 and the upright... Then, by moving the push-pull head 25, it is deflected to a horizontal position under the action of the rotating rod. This pushes the push-pull rod 9, causing the movable frame 15 to slide along the guide rod 29 within the outer sleeve 4. During this sliding process, the movable frame 15 causes the pressure plate 16 to contact the inclined surface at the bottom of the pressure block 14, generating pressure. This, in turn, pushes the pressure block 14, causing the lifting plate 12 to move upwards. The lifting plate 12 then lifts the pressure rod 13, pressing and supporting the bottom limiting end 21 of the locking sleeve 11. This, in turn, pushes the entire locking sleeve 11 to slide and press against the outside of the joint ball 10, thus locking the joint ball 10. After the intelligent safety fence body 1 is locked, moving the push-pull head 25 deflects it via the rotating rod. This causes the end of the push-pull head 25 to deflect between the knob 6 and the outer sleeve 4, allowing the protrusion 26 on the push-pull head 25 to embed into the groove 30 on the knob 6, forming a limiting lock on the push-pull rod 9 and the movable frame 15, ensuring the working effect of the locking component. At the same time, under the action of the spring 24, the push-pull rod 9 and the push-pull head 25 will also generate a squeezing force on the knob 6, realizing an auxiliary limiting effect on the knob 6, preventing accidental touch of the knob 6 from affecting the overall stability of the device, thereby further enhancing the overall stability of the entire intelligent early warning safety fence after installation and adjustment and locking, and making the structures of the adjustment component, locking component and lifting component cooperate with each other, improving and strengthening their respective working effects, thus perfecting the entire technical solution.

[0045] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
