Technical Field
[0001] This invention relates to the field of security monitoring technology, specifically to an intelligent security monitoring device for construction sites. Background Technology
[0002] The intelligent security monitoring device used at the construction site is a comprehensive system with video surveillance as its core, integrating AI intelligent analysis, environmental perception, early warning linkage, and remote management.
[0003] CN114979570B discloses an intelligent security monitoring device for construction sites, including a mounting frame and multiple security monitoring devices. The mounting frame comprises vertical poles perpendicular to each other and multiple horizontal poles. One end of each horizontal pole is connected to the top of the vertical pole, and the other end is connected to a security monitoring device via a hanging rod. All the horizontal poles form a circular structure. The security monitoring device is a surveillance camera. This device uses a mounting frame with one vertical pole and multiple horizontal poles, with multiple surveillance cameras installed on each horizontal pole, enabling large-area circumferential monitoring of the construction site without blind spots. The intelligent security monitoring device for construction sites can automatically clean the surveillance cameras, preventing dust and debris from the construction site from affecting the quality of the monitoring images.
[0004] During use, the camera has a limited monitoring angle, the connecting wires become tangled when the camera rotates, and dust accumulates on the camera surface after long-term use at the construction site. Therefore, an intelligent security monitoring device for construction sites is proposed to solve the above-mentioned problems. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide an intelligent security monitoring device for construction sites, which addresses the shortcomings of the prior art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an intelligent security monitoring device for construction sites. The device includes a support column, a power distribution box fixedly connected to the top of the support column, a camera installed at the bottom of the support column, a rotating mechanism, a winding mechanism, and a cleaning mechanism installed at the bottom of the support column. Due to the fixing and limiting effect of the fixed rod, the sliding rod reciprocates on the circumferential surface of the reciprocating screw. The reciprocating movement of the sliding rod drives the telescopic plate to move, and the telescopic plate causes the fixed bracket to rotate. This allows the camera to rotate and swing up and down simultaneously. The camera can automatically cruise and scan according to a preset route and speed, periodically checking the entire monitoring area to ensure there are no blind spots, greatly improving the flexibility, coverage, and efficiency of the camera.
[0007] The rotating mechanism includes a disc, a rotating disk, a rotating shaft, an L-shaped plate, a reciprocating lead screw, a fixed rod, a sliding rod, a spur gear, a telescopic plate, and a fixed bracket. The disc is fixedly connected to the bottom of the support column. The rotating disk is rotatably connected to the inner wall of the disc. The rotating shaft is fixedly connected to the inner wall of the rotating disk. A motor is installed on the inner wall of the distribution box, and the rotating shaft is fixedly connected to the motor output end. The L-shaped plate is fixedly connected to the bottom of the rotating disk. The reciprocating lead screw is rotatably connected to the inner wall of the L-shaped plate. The fixed rod is fixedly connected to the inner wall of the L-shaped plate. The sliding rod is slidably connected to the circumferential surface of the reciprocating lead screw. The spur gear is fixedly connected to the circumferential surface of the reciprocating lead screw. The telescopic plate is fixedly connected to the left side of the sliding rod, and the fixed bracket is rotatably connected to the rear of the telescopic plate.
[0008] Preferably, the rotating mechanism includes teeth, a wire harness, a insert plate, a fixing slot, a locking plate, and a first elastic telescopic rod. The teeth are fixedly connected to the inner wall of the disc, the fixing slot is fixedly connected to the right side of the camera, the insert plate is inserted into the inner wall of the fixing slot, the wire harness is connected to the inner wall of the insert plate, the locking plate is slidably connected to the right side of the camera, and the first elastic telescopic rod is fixedly connected to the right side of the camera. The locking plate can move up and leave the fixing bracket, thereby freeing the locking plate from the fixing bracket. This allows the operator to disassemble and install the camera, making disassembly easier and preventing damage during disassembly that could render the camera inoperable, thus ensuring the continuity and reliability of the security camera.
[0009] Preferably, the first fixed rod is fixedly connected to the inner wall of the rotating disk, the sliding rod is slidably connected to the circumferential surface of the first fixed rod, the fixed bracket is in contact with the camera, the first spur gear meshes with the teeth, the locking plate is in contact with the inner wall of the fixed bracket, the locking plate is slidably connected to the inner wall of the fixed slot, the telescopic end of the first elastic telescopic rod is fixedly connected to the front and rear sides of the locking plate, and the insert plate is in contact with the locking plate. Ultimately, when the camera swings upward, the winding spool unwinds the wire harness, and when the camera swings downward, the winding spool winds up the wire harness. This actively compensates for changes in the length of the wire harness, maintaining a relatively constant tension, effectively preventing overstretching, ensuring that the wire harness is always under control during camera movement, avoiding damage, tangling, or interference with camera movement, thereby ensuring the long-term stable operation and service life of the equipment.
[0010] Preferably, the winding mechanism includes a rack, a second spur gear, a winding shaft, a first fixing plate, a fixing frame, a ring, and a protrusion. The rack is fixedly connected to the right side of the slide rod, the fixing frame is fixedly connected to the circumferential surface of the disc, the first fixing plate is fixedly connected to the bottom of the fixing frame, the winding shaft is rotatably connected to the inner wall of the first fixing plate, the second spur gear is fixedly connected to the circumferential surface of the winding shaft, the ring is rotatably connected to the circumferential surface of the disc, and the protrusion is fixedly connected to the circumferential surface of the ring.
[0011] Preferably, the winding mechanism further includes a belt, a second reciprocating lead screw, a second fixed plate, a second fixed rod, a slider, a first brush, and a hanging ring. The belt drive is connected to the circumferential surface of the winding shaft. The second fixed plate is fixedly connected to the bottom of the fixed frame. The second reciprocating lead screw is rotatably connected to the inner wall of the second fixed plate. The second fixed rod is fixedly connected to the inner wall of the second fixed plate. The slider is movably connected to the circumferential surface of the second reciprocating lead screw. The first brush is fixedly connected to the right side of the slider. The hanging ring is fixedly connected to the bottom of the slider.
[0012] Preferably, the rack meshes with the second spur gear, the rack is slidably connected to the inner wall of the fixed frame, the wire harness is wound on the winding shaft, the second reciprocating screw is driven by the circumferential surface of the belt, the slider is slidably connected to the circumferential surface of the second fixed rod, the slider contacts the wire harness, and the hanging ring is sleeved on the circumferential surface of the wire harness. The movement of the slider drives the first brush to move, thereby scraping the surface of the wire harness, keeping the wire harness clean, and preventing dust accumulation from causing physical, chemical, or electrical damage. This ensures the insulation performance, heat dissipation efficiency, and mechanical strength of the wire harness. During the movement of the slider, the movement of the slider drives the hanging ring to move, thereby arranging the threads of the wire harness together, which can effectively reduce the overall temperature of the wire harness, extend its service life, and better avoid the phenomenon of wire harness tangling.
[0013] Preferably, the cleaning mechanism includes a square box, a second brush, an air bladder, a rotating rod, a lever, a second L-shaped plate, a contact plate, and a second elastic telescopic rod. The square box is fixedly connected to the bottom of the support column, the second brush is fixedly connected to the inner wall of the square box, the air bladder is fixedly connected to the rear of the square box, the rotating rod is rotatably connected to the inner wall of the square box via a torsion spring, the lever is fixedly connected to the inner wall of the rotating rod, the second L-shaped plate is slidably connected to the inner wall of the square box, the contact plate is fixedly connected to the top of the rotating rod, and the second elastic telescopic rod is fixedly connected to the inner wall of the square box. When the protrusion moves and contacts the second L-shaped plate, the camera contacts the second brush. As the protrusion continues to move, the second brush can wipe the camera lens. Wiping the lens can effectively remove these deposits, restore the light transmittance of the lens, and ensure that the image captured by the camera is clear and sharp, providing high-quality images for monitoring and evidence collection. Regular wiping can reduce the damage of stains to the coating.
[0014] Preferably, the rotating rod contacts the lever, the contact plate contacts the second L-shaped plate, the telescopic end of the second elastic telescopic rod is fixedly connected to the top of the second L-shaped plate, and the rotating rod is rotatably connected to the inner wall of the second brush holder via a torsion spring. During the downward movement of the second L-shaped plate, the downward movement of the second L-shaped plate causes the contact plate to move downward, and the downward movement of the contact plate causes the rotating rod to rotate, thereby allowing the lever to move upward, thus realizing the lever's vibration of the second brush. If not cleaned for a long time, dust and dirt will accumulate at the base of the bristles, causing the bristles to harden, lose elasticity, and even clump together. This will reduce the cleaning efficiency of the second brush and may scratch the mirror surface during wiping.
[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. The construction site uses an intelligent security monitoring device. Through the cooperation of a disc, rotating disk, rotating shaft, L-shaped plate, reciprocating screw, fixed rod, sliding rod, spur gear, and telescopic plate, the camera can rotate and swing up and down simultaneously. The camera can automatically cruise and scan according to a preset route and speed, periodically checking the entire monitoring area to ensure there are no blind spots. This greatly improves the flexibility, coverage, and efficiency of the camera. At the same time, the camera can be disassembled and installed, making it easier for staff to disassemble and preventing damage during disassembly that could render the camera inoperable, thus ensuring the continuity and reliability of the security camera.
[0016] 2. The construction site utilizes an intelligent security monitoring device. Through the coordinated operation of racks, spur gears, winding spools, fixing plates, fixing frames, rings, protrusions, belts, and reciprocating screws, it can actively compensate for changes in the length of the wire harness, maintaining a relatively constant tension. This effectively prevents overstretching and ensures the wire harness remains under control during camera movement, avoiding damage, tangling, or interference with camera movement. This ensures long-term stable operation and extended lifespan of the equipment. Simultaneously, it can scrape the surface of the wire harness, keeping it clean and preventing dust accumulation that could cause physical, chemical, or electrical damage. This protects the wire harness's insulation performance, heat dissipation efficiency, and mechanical strength. Furthermore, the device allows for the arrangement of threads within the wire harness, effectively reducing its overall temperature, extending its lifespan, and further preventing tangling.
[0017] 3. The construction site uses an intelligent security monitoring device. Through the cooperation of the square box, brush II, airbag, rotating rod, lever, L-shaped plate II, contact plate, and elastic telescopic rod II, the brush II can wipe the camera lens. Wiping the lens can effectively remove these attachments, restore the lens's light transmittance, and ensure that the image captured by the camera is clear and sharp, providing high-quality images for monitoring and evidence collection. Regular wiping can reduce the damage of stains to the coating. At the same time, the lever can shake the brush II. If it is not cleaned for a long time, dust and dirt will accumulate at the base of the bristles, causing the bristles to harden, lose elasticity, and even clump together. This will reduce the cleaning efficiency of the brush II and may scratch the lens during wiping. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Please see Figures 1-8 One embodiment of the present invention is: an intelligent security monitoring device for construction sites, including a support column 1, a power distribution box 2 fixedly connected to the top of the support column 1, a camera 3 installed at the bottom of the support column 1, a rotating mechanism 4 installed at the bottom of the support column 1, a winding mechanism 5 installed at the bottom of the support column 1, and a cleaning mechanism 6 installed at the bottom of the support column 1, so that the camera 3 can rotate and swing up and down at the same time, and the camera 3 can automatically cruise and scan according to a preset route and speed, periodically checking the entire monitoring area to ensure that there are no blind spots, which greatly improves the flexibility, coverage and efficiency of the camera 3.
[0022] The rotating mechanism 4 includes a disc 401, a rotating disk 402, a rotating shaft 403, an L-shaped plate 404, a reciprocating lead screw 405, a fixed rod 406, a sliding rod 407, a spur gear 408, a telescopic plate 409, and a fixed bracket 410. The disc 401 is fixedly connected to the bottom of the support column 1, the rotating disk 402 is rotatably connected to the inner wall of the disc 401, and the rotating shaft 403 is fixedly connected to the inner wall of the rotating disk 402. A motor is installed on the inner wall of the distribution box 2, and the rotating shaft 403 is fixedly connected to the output end of the motor. L-shaped plate 404 is fixedly connected to the bottom of rotating disk 402, reciprocating screw 405 is rotatably connected to the inner wall of L-shaped plate 404, fixed rod 406 is fixedly connected to the inner wall of L-shaped plate 404, slide rod 407 is slidably connected to the circumferential surface of reciprocating screw 405, spur gear 408 is fixedly connected to the circumferential surface of reciprocating screw 405, telescopic plate 409 is fixedly connected to the left side of slide rod 407, and fixed bracket 410 is rotatably connected to the rear of telescopic plate 409.
[0023] The rotating mechanism 4 includes a tooth 411, a wire harness 412, a plug 413, a fixing slot 414, a locking plate 415, and an elastic telescopic rod 416. The tooth 411 is fixedly connected to the inner wall of the disc 401. The fixing slot 414 is fixedly connected to the right side of the camera 3. The plug 413 is inserted into the inner wall of the fixing slot 414. The wire harness 412 is connected to the inner wall of the plug 413. The locking plate 415 is slidably connected to the right side of the camera 3. The elastic telescopic rod 416 is fixedly connected to the right side of the camera 3. The rotating mechanism 4 allows for the disassembly and installation of the camera 3, making disassembly easier for workers and preventing damage during disassembly that could render the camera 3 inoperable. This ensures the continuity and reliability of the camera 3. Since the construction site may change location as the construction period progresses, the camera 3 in the area where construction is completed must be disassembled and placed in the new construction area.
[0024] Fixed rod 406 is fixedly connected to the inner wall of rotating disk 402, sliding rod 407 is slidably connected to the circumferential surface of fixed rod 406, fixed bracket 410 is in contact with camera 3, spur gear 408 meshes with tooth 411, locking plate 415 is in contact with the inner wall of fixed bracket 410, locking plate 415 is slidably connected to the inner wall of fixed slot 414, elastic telescopic rod 416 is fixedly connected to the front and rear sides of locking plate 415 at its telescopic end, and insert plate 413 is in contact with locking plate 415.
[0025] Working principle: When the device is started, the operator starts the motor. The motor output drives the rotating shaft 403 to rotate, which in turn drives the rotating disk 402 to rotate. The rotating disk 402 then drives the L-shaped plate 404 to rotate, which in turn drives the reciprocating screw 405 to rotate. The reciprocating screw 405 then drives the spur gear 408 to rotate. Due to the meshing of the spur gear 408 with the teeth 411, the spur gear 408 itself rotates during its rotation, which in turn drives the reciprocating screw 405 to rotate. The reciprocating screw 405 rotates, causing the slide bar 407 to rotate. Due to the fixing and limiting effect of the fixed rod 406, the slide bar 407 reciprocates on the circumferential surface of the reciprocating screw 405. The reciprocating movement of the slide bar 407 causes the telescopic plate 409 to move. The telescopic plate 409 causes the fixed bracket 410 to rotate, thereby enabling the camera 3 to rotate and swing up and down. The camera 3 can automatically cruise and scan according to the preset route and speed, periodically checking the entire monitoring area to ensure there are no blind spots, greatly improving the flexibility, coverage and efficiency of the camera 3.
[0026] When camera 3 needs to be disassembled, the operator pulls the insert plate 413 out of the fixing slot 414. At this time, the top of the locking plate 415 is no longer limited by the insert plate 413. Due to the reset action of the spring of the elastic telescopic rod 416, the elastic telescopic rod 416 moves upward. The upward movement of the elastic telescopic rod 416 drives the locking plate 415 to move upward. The upward movement of the locking plate 415 allows it to leave the fixing bracket 410, thereby freeing it from the locking of the fixing bracket 410. This allows the operator to disassemble and install camera 3, making disassembly easier and preventing damage during disassembly that could render camera 3 inoperable, thus ensuring the continuity and reliability of the security camera 3.
[0027] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the winding mechanism 5 includes a rack 501, a second spur gear 502, a winding shaft 503, a first fixing plate 504, a fixing frame 505, a ring 506, and a protrusion 507. The rack 501 is fixedly connected to the right side of the slide rod 407, the fixing frame 505 is fixedly connected to the circumferential surface of the disc 401, the first fixing plate 504 is fixedly connected to the bottom of the fixing frame 505, the winding shaft 503 is rotatably connected to the inner wall of the first fixing plate 504, the second spur gear 502 is fixedly connected to the circumferential surface of the winding shaft 503, the ring 506 is rotatably connected to the circumferential surface of the disc 401, and the protrusion 507 is fixedly connected to the circumferential surface of the ring 506.
[0028] The winding mechanism 5 also includes a belt 508, a reciprocating screw 509, a fixed plate 510, a fixed rod 511, a slider 512, a brush 513, and a hanging ring 514. The belt 508 is driven and connected to the circumferential surface of the winding shaft 503. The fixed plate 510 is fixedly connected to the bottom of the fixed frame 505. The reciprocating screw 509 is rotatably connected to the inner wall of the fixed plate 510. The fixed rod 511 is fixedly connected to the inner wall of the fixed plate 510. The slider 512 is movably connected to the circumferential surface of the reciprocating screw 509. The brush 513 is fixedly connected to the right side of the slider 512. The hanging ring 514 is fixedly connected to the bottom of the slider 512. This allows for active compensation of the length changes of the wire harness 412, ensuring that it always maintains a relatively constant tension. This effectively avoids excessive stretching and ensures that the wire harness 412 is always under control during the movement of the camera 3, preventing damage, entanglement, or interference with the movement of the camera 3. This ensures the long-term stable operation and service life of the equipment.
[0029] Rack 501 meshes with spur gear 502 and slides on the inner wall of the fixed frame 505. Wire harness 412 is wound on the winding shaft 503. Reciprocating screw 509 is circumferentially connected to belt 508. Slider 512 slides on the circumferential surface of fixed rod 511 and contacts wire harness 412. Hanging ring 514 is sleeved on the circumferential surface of wire harness 412 and can simultaneously scrape the surface of wire harness 412 to keep it clean and prevent dust accumulation from causing physical, chemical, or electrical damage. This ensures the insulation performance, heat dissipation efficiency, and mechanical strength of wire harness 412. Furthermore, the threads of wire harness 412 can be arranged together, effectively reducing the overall temperature of wire harness 412, extending its service life, and better preventing wire harness 412 from tangling.
[0030] Cleaning mechanism 6 includes a square box 601, a second brush 602, an air bladder 603, a rotating rod 604, a lever 605, an L-shaped plate 606, a contact plate 607, and a second elastic telescopic rod 608. The square box 601 is fixedly connected to the bottom of the support column 1. The second brush 602 is fixedly connected to the inner wall of the square box 601. The air bladder 603 is fixedly connected to the rear of the square box 601. The rotating rod 604 is rotatably connected to the inner wall of the square box 601 via a torsion spring. The lever 605 is fixedly connected to the inner wall of the rotating rod 604. The L-shaped plate 606 is slidably connected to the inner wall of the square box 601, the contact plate 607 is fixedly connected to the top of the rotating rod 604, and the elastic telescopic rod 608 is fixedly connected to the inner wall of the square box 601, so that the brush 602 can wipe the mirror surface of the camera 3. Wiping the mirror surface can effectively remove these attachments, restore the light transmittance of the lens, and ensure that the image captured by the camera 3 is clear and sharp, providing high-quality images for monitoring and evidence collection. Regular wiping can reduce the damage of stains to the coating.
[0031] The rotating rod 604 contacts the lever 605, the contact plate 607 contacts the L-shaped plate 606, the telescopic end of the elastic telescopic rod 608 is fixedly connected to the top of the L-shaped plate 606, and the rotating rod 604 is rotatably connected to the inner wall of the fixed seat of the brush 602 through a torsion spring. At the same time, the lever 605 can shake the brush 602. If it is not cleaned for a long time, dust and dirt will accumulate at the root of the bristles, causing the bristles to harden, lose elasticity, or even clump. This will reduce the cleaning efficiency of the brush 602 and may scratch the mirror surface during wiping.
[0032] Working principle: When the device is started, as the slide bar 407 moves up and down, it drives the rack 501 to move. Due to the meshing of the rack 501 and the spur gear 502, the spur gear 502 rotates during the movement of the rack 501. The rotation of the spur gear 502 drives the winding shaft 503 to rotate, which in turn winds the wire harness 412. Ultimately, when the camera 3 swings upward, the winding shaft 503 unwinds the wire harness 412, and when the camera 3 swings downward, the winding shaft 503 winds up the wire harness 412. This actively compensates for changes in the length of the wire harness 412, keeping it at a relatively constant tension. This effectively avoids overstretching and ensures that the wire harness 412 remains under control during the movement of the camera 3, preventing damage, tangling, or interference with the movement of the camera 3. This ensures the long-term stable operation and service life of the device. During the rotation of the winding shaft 503, the rotation of the winding shaft 503 drives the belt 508 to rotate, the rotation of the belt 508 drives the reciprocating screw 509 to rotate, and the rotation of the reciprocating screw 509 drives the slider 512 to rotate. Due to the limiting function of the fixed rod 511, the slider 512 moves back and forth on the circumferential surface of the reciprocating screw 509. The movement of the slider 512 drives the brush 513 to move, thereby scraping the surface of the wire harness 412, keeping the wire harness 412 clean, and preventing dust accumulation from causing physical, chemical, or electrical damage. This ensures the insulation performance, heat dissipation efficiency, and mechanical strength of the wire harness 412. During the movement of the slider 512, the movement of the slider 512 drives the hanging ring 514 to move, thereby arranging the threads of the wire harness 412 together. This effectively reduces the overall temperature of the wire harness 412, extends its service life, and better avoids the phenomenon of the wire harness 412 getting tangled.
[0033] During the rotation of the slide bar 407, the rotation of the slide bar 407 drives the fixed frame 505 to rotate, the rotation of the fixed frame 505 drives the ring 506 to rotate, and the rotation of the ring 506 drives the protrusion 507 to rotate. When the protrusion 507 moves and contacts the L-shaped plate 606, the camera 3 contacts the brush 602. When the protrusion 507 continues to move, the brush 602 can wipe the lens of the camera 3. Wiping the lens can effectively remove these deposits, restore the light transmittance of the lens, and ensure that the image captured by the camera 3 is clear and sharp, providing high-quality images for monitoring and evidence collection. Regular wiping can reduce the damage of stains to the coating. When the protrusion 507 moves and contacts the L-shaped plate 606, the inclined surface of the protrusion 507 causes the L-shaped plate 606 to move downward. The downward movement of the L-shaped plate 606 compresses the air bladder 603, allowing the air bladder 603 to blow air onto the mirror surface of the camera 3. This removes light dust and floating dust from the mirror surface quickly and effectively in a non-contact manner, avoiding physical damage that may be caused by wiping. During the downward movement of the L-shaped plate 606, the downward movement of the L-shaped plate 606 causes the contact plate 607 to move downward. The downward movement of the contact plate 607 causes the rotating rod 604 to rotate, which in turn causes the lever 605 to move upward, thereby making the lever 605 vibrate the brush 602. If not cleaned for a long time, dust and dirt will accumulate at the base of the bristles, causing the bristles to harden, lose elasticity, and even clump together. This will reduce the cleaning efficiency of the brush 602 and may scratch the mirror surface during wiping.
