Description

Technical Field

[0001] This invention relates to the field of protective fence equipment technology, and in particular discloses a reusable and mobile intelligent alarm protective fence. Background Technology

[0002] The intelligent alarm protective fence is a comprehensive on-site temporary safety isolation device that integrates physical barriers and intelligent status sensing alarm functions. Its primary core function is to provide a set of rigid or semi-rigid physical isolation units with specific structural strength, which can be interconnected and repeatedly disassembled, transported, and moved. Through the rapid assembly and combination of these units in a preset target space area, a temporary continuous physical isolation barrier can be constructed to effectively prevent unauthorized personnel from passing through at will and to deter unauthorized intrusion. The protective fence, through its inherent structure, disassembly and mobility characteristics, and spatial reconfiguration capabilities, meets the requirements for safety isolation, flexible spatial distribution, and equipment reusability. The embedded intelligent alarm function gives the traditional physical isolation fence the ability to autonomously detect and immediately warn of abnormal boundary conditions, greatly enhancing the effectiveness of real-time control over the safety status of the isolated area.

[0003] Patent CN107345459A discloses a novel protective fence. The technical solution of this patent includes a first fence frame and a second fence frame. Each of the first and second fence frames has two sets of connecting rods at their closest points. A rotating connecting pipe connects the two sets of connecting rods at the same height, and the rotating connecting pipe has movable holes that mate with the connecting rods. Each of the first and second fence frames has two sets of moving wheels at its bottom, and a rotating connecting rod connects the two sets of moving wheels. One end of each set of rotating connecting rods is rotatably connected to the center of the bottom of the first and second fence frames, respectively. A balance support rod is sleeved on the outside of each set of rotating connecting rods, and a first limiting baffle is provided at the bottom of each set of rotating connecting rods. However, this patent is not convenient for storage and folding, and is very inconvenient for transfer.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] As attached Figure 1 To the attached Figure 4 As shown, this invention discloses a reusable and movable intelligent alarm protective fence, including a telescopic plate 1, an installation mechanism 2, a telescopic mechanism 3, and a storage mechanism 4. The installation mechanism 2 comprises four sets, symmetrically mounted on the telescopic plate 1. Each installation mechanism 2 includes an installation cylinder 201, a motor 203, a locking assembly, and a lifting assembly.

The rod storage assembly can store the four sets of hinge rods, and each set of mounting cylinder storage assembly can store each mounting cylinder 201.

[0031] As attached Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 8 and attached Figure 9As shown, the telescopic plate 1 includes four fixed plates 101 and four sliding plates 102. Each fixed plate 101 has a universal wheel 103 installed at its lower part. The universal wheel 103 has a self-locking function. Each sliding plate 102 is slidably installed between two adjacent fixed plates 101. The four fixed plates 101 and four sliding plates 102 form a closed rectangular structure. Each fixed plate 101 is provided with a mounting hole 207. A base plate 204 is installed in each mounting hole 207. The base plate 204 is fastened to the lower part of the mounting cylinder 201 by fastening bolts. The base plate 204 is coaxial with the mounting cylinder 201. The outer surface of the base plate 204 is provided with a positioning hole 205. The inner wall of the mounting hole 207 is provided with a pair of rectangular grooves. The locking assembly includes a second connecting shaft 211. The second connecting shaft 211 is fixedly installed on the inner wall of the rectangular groove of the mounting hole 207. The outer surface of the second connecting shaft 211 is... An arc-shaped block 210 is slidably installed inside the rectangular groove of the mounting hole 207. A spring 212 is wound around the outside of the second connecting shaft 211. One end of the spring 212 is fixedly connected to the outer surface of the second connecting shaft 211, and the other end of the spring 212 is fixedly connected to the end of the arc-shaped block 210 away from the mounting cylinder 201. Multiple infrared sensors, logic control circuits, and buzzers are installed on the outer surface of each mounting cylinder 201. The multiple infrared sensors are installed in a circumferential shape on the outer surface of the mounting cylinder 201. The multiple infrared sensors are electrically connected to the logic control circuit. The logic control circuit is electrically connected to the motor 203 and the buzzer. A remote control module is also installed on the outer surface of the mounting cylinder 201. The remote control module is electrically connected to the logic control circuit and to the remote control. The remote control has three buttons: on, off, and stop. The three buttons control the forward rotation, reverse rotation, and stop of the motor 203, respectively.

[0032] As attached Figure 7 Appendix Figure 8 and attached Figure 9As shown, the arc-shaped block 210 has an arc-shaped surface facing the mounting cylinder 201. The radius of the arc surface of the arc-shaped block 210 is equal to the radius of the inner wall of the mounting hole 207. An inclined surface is provided on the arc surface of the arc-shaped block 210. The distance between the inclined surface of the arc-shaped block 210 and the bottom of the inner wall of the mounting hole 207 gradually increases along the direction away from the mounting cylinder 201. The diameter of the inner wall of the mounting hole 207 is equal to the diameter of the outer surface of the chassis 204. A top shaft 213 is fixedly installed on the arc surface of the arc-shaped block 210. The diameter of the top shaft 213 is equal to the diameter of the positioning hole 205, and the length of the top shaft 213 is equal to the depth of the positioning hole 205. The motor 203 is installed on the upper part of the mounting cylinder 201. Two mutually perpendicular side grooves 202 are provided on the side of the mounting cylinder 201. The lifting assembly includes a bidirectional threaded rod 206, which is connected to the mounting cylinder 201. The biaxially aligned bidirectional threaded rod 206 is rotatably mounted inside the mounting cylinder 201. The bidirectional threaded rod 206 is connected to the output end of the motor 203 via a coupling. Each fixed plate 101 is provided with a first receiving groove 214, which can completely accommodate the motor 203 and the coupling. The output end of the motor 203 is rotatably connected to the mounting cylinder 201. The outer surface of the bidirectional threaded rod 206 is provided with two sections of threads with opposite helical directions. The section between the two sections of threads is a smooth rod. The two sections of threads of the bidirectional threaded rod 206 are of equal length. A lifting block 208 is installed on the outer side of each thread section of the bidirectional threaded rod 206, and the lifting block 208 and the threads on the outer surface of the bidirectional threaded rod 206 form a helical fit. The two sections of threads of the bidirectional threaded rod 206 have equal thread pitch.

[0033] When the fence needs to be deployed, press the start button on the remote control. The remote control module and logic control circuit control the motor 203 to start. The motor 203 drives the bidirectional threaded rod 206 to rotate. The bidirectional threaded rod 206 drives the two lifting blocks 208 to move away from each other. The lifting blocks 208 drive the first connecting rod 301 and the second connecting rod 302 to move through the first connecting shaft 209, which in turn drives the four fixed plates 101 to move away from each other, thereby expanding the range of the fixed plates 101. The working time of the motor 203 is controlled by the remote control to adjust the expansion range of the fixed plates 101. When the infrared sensor detects an object or living creature rapidly approaching, the infrared sensor sends an electrical signal to the logic control circuit, which then controls the buzzer to start, thus issuing an alarm.

[0034] As attached Figure 6 Appendix Figure 7 and attached Figure 8As shown, the lifting block 208 is formed by two short rods fixedly connected vertically. The two short rods of the lifting block 208 are slidably installed in each side groove 202. A first connecting shaft 209 is fixedly installed at one end of each short rod outside the side groove 202. The hinge rod group includes multiple first connecting rods 301 and second connecting rods 302. The number of first connecting rods 301 and second connecting rods 302 is equal. Multiple first connecting rods 301 and second connecting rods 302 are continuously and alternately hinged together. The lengths of the first connecting rods 301 and second connecting rods 302 are equal and the hinge position is located at the center of the first connecting rods 301 and second connecting rods 302. The first connecting rods 301 and second connecting rods 302 are respectively connected to the first connecting shafts 209 of different short rods installed on the same bidirectional threaded rod 206. The first connecting rods 301 and second connecting rods 302 can be detached from the first connecting shafts 209. All first connecting rods 301 and second connecting rods 302 can be separated individually.

[0035] As attached Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8 and attached Figure 11 As shown, the rod storage assembly includes two side panels 401. The inner wall width of the side panels 401 is greater than half the length of the first connecting rod 301 and the second connecting rod 302. The two side panels 401 are respectively fixedly installed between two adjacent fixed plates 101. A middle plate 403 is slidably installed between the two side panels 401. A connecting block 402 is fixedly installed at the end of each side panel 401 away from the middle plate 403. A mounting shaft 408 is rotatably installed between the two connecting blocks 402. The connecting blocks 402 and the side panels 401 can slide along the outer surface of the mounting shaft 408. Two first flip plates 409 are symmetrically rotatably installed on the outer side of the mounting shaft 408. A second flip plate 410 is slidably installed between the two first flip plates 409. The second flip plate 410 is rotatably connected to the connecting block 402. The width of the first flip plate 409 is equal to that of the side panel 401. The second flip plate 410 is fixedly installed on the outside of the mounting shaft 408. Two second storage slots 404 and one limiting slot 405 are symmetrically arranged on each fixed plate 101. The width of the second storage slot 404 is equal to the outer diameter of the mounting cylinder 201. The length of the limiting slot 405 is greater than the length of the second storage slot 404. The length of the second storage slot 404 is equal to half the length of the mounting cylinder 201. One end face of the limiting slot 405 coincides with the end face of the second storage slot 404.

[0036] The output end of motor 203 rotates in reverse, and the bidirectional threaded rod 206 drives the two lifting blocks 208 to move closer to each other. The lifting blocks 208 drive the first connecting rod 301 and the second connecting rod 302 to move through the first connecting shaft 209, thereby driving the four fixed plates 101 to move closer to each other, thus achieving the purpose of shrinking the range of the fixed plates 101. When the four fixed plates 101 are in contact, press the stop button on the remote control. At this time, motor 203 stops working. Then remove the coupling and disassemble it to separate the coupling from the bidirectional threaded rod 206. Place the coupling and motor 203 in the first storage slot 214. Then rotate the first flip plate 409 and remove all the first connecting rods 301 and the second connecting rods 302 and put them into the side panel 401. After putting them all into the side panel 401, cover the first flip plate 409 to complete the storage of the first connecting rods 301 and the second connecting rods 302.

[0037] As attached Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8 and attached Figure 10 As shown, the mounting cylinder storage assembly includes a fixing rod 406, which is fixedly installed in a limiting groove 405. An end cap 407 is fixedly installed at the end of the fixing rod 406 away from the mounting hole 207, and the diameter of the end cap 407 is larger than the diameter of the fixing rod 406. A pressure block 414 is slidably installed on the outside of the fixing rod 406, and the pressure block 414 is slidably installed in the limiting groove 405. A pair of arc-shaped grooves 415 are provided on the lower side of the pressure block 414, and the radius of the arc-shaped grooves 415 is equal to the radius of the outer surface of the mounting cylinder 201. A threaded hole is provided on the side of the pressure block 414, and a one-way helical rod 413 is installed in the threaded hole of the pressure block 414. The one-way helical rod 413 and the threaded hole of the pressure block 414 form a helical engagement. A fixing block 412 is rotatably installed on the outside of the one-way helical rod 413, and the fixing block 412 is fixedly installed on the fixing plate 101. A handle 411 is fixedly installed at the end of the one-way helical rod 413 away from the pressure block 414.

[0038] Pushing the arc-shaped block 210, the spring 212 is compressed by the arc-shaped block 210, causing the top shaft 213 to gradually disengage from the positioning hole 205, thereby disengaging the chassis 204 from the mounting hole 207. The fastening bolts connecting the chassis 204 and the mounting cylinder 201 are then removed. After removing the fastening bolts, the chassis 204 is placed back into the mounting hole 207. The arc-shaped block 210 is then released, and the top shaft 213 is reinserted into the positioning hole 205 under the action of the spring 212. 5. This completes the positioning of the chassis 204. The mounting cylinder 201 and the bidirectional threaded rod 206 are placed into the second storage slot 404. Then, the handle 411 is turned, which drives the one-way screw rod 413 to rotate. The one-way screw rod 413 drives the pressure block 414 to slide along the inner wall of the limiting groove 405. The mounting cylinder 201 is pressed by the cooperation of the arc groove 415 and the second storage slot 404, thereby completing the storage of the mounting cylinder 201 and the bidirectional threaded rod 206.

[0039] The working principle of this embodiment is as follows:

[0040] (i) When the fence needs to be deployed, press the start button on the remote control. The remote control module and logic control circuit control the motor 203 to start. The motor 203 drives the bidirectional threaded rod 206 to rotate. The bidirectional threaded rod 206 drives the two lifting blocks 208 to move away from each other. The lifting blocks 208 drive the first connecting rod 301 and the second connecting rod 302 to move through the first connecting shaft 209, thereby driving the four fixed plates 101 to move away from each other, so as to expand the range of the fixed plates 101. The working time of the motor 203 is controlled by the remote control to adjust the expansion range of the fixed plates 101.

[0041] (ii) When the infrared sensor detects that an object or living organism is rapidly approaching, the infrared sensor sends an electrical signal to the logic control circuit, which then controls the buzzer to start, thereby issuing an alarm.

[0042] (III) When folding is required, press the close button on the remote control. The output end of motor 203 rotates in the reverse direction. The bidirectional threaded rod 206 drives the two lifting blocks 208 to move closer to each other. The lifting blocks 208 drive the first connecting rod 301 and the second connecting rod 302 to move through the first connecting shaft 209, thereby driving the four fixing plates 101 to move closer to each other, thus achieving the purpose of shrinking the range of the fixing plates 101. When the four fixing plates 101 are in contact, press the stop button on the remote control. At this time, motor 203... Stop the operation, then remove the coupling and disassemble it to separate the coupling from the double-threaded rod 206. Place the coupling and motor 203 in the first storage slot 214, then rotate the first flip plate 409 to remove all the first connecting rods 301 and second connecting rods 302 and put them into the side panel 401. After all the first connecting rods 301 and second connecting rods 302 are put into the side panel 401, cover the first flip plate 409 to complete the storage of the first connecting rods 301 and second connecting rods 302.

[0043] (iv) Then push the arc-shaped surface of the arc block 210. The arc block 210 compresses the spring 212, causing the top shaft 213 to gradually disengage from the positioning hole 205, thereby achieving the purpose of disengaging the chassis 204 from the mounting hole 207. Remove the fastening bolts at the connection between the chassis 204 and the mounting cylinder 201. After removing the fastening bolts, put the chassis 204 back into the mounting hole 207. Then release the arc block 210. Under the action of the spring 212, the top shaft 213 is reinserted into the positioning hole. Hole 205 is used to position the chassis 204. The mounting cylinder 201 and the bidirectional threaded rod 206 are placed into the second storage groove 404. Then, the handle 411 is turned, which drives the one-way screw rod 413 to rotate. The one-way screw rod 413 drives the pressure block 414 to slide along the inner wall of the limiting groove 405. The mounting cylinder 201 is pressed by the cooperation of the arc groove 415 and the second storage groove 404, thereby completing the storage of the mounting cylinder 201 and the bidirectional threaded rod 206.
