Description

Technical Field

[0001] This invention relates to lightning protection technology for broadcast television transmission towers, specifically to a lightning protection photoelectric signal isolation protection device for broadcast television transmission towers. Background Technology

[0002] As the core infrastructure for signal transmission, broadcast and television transmission towers are typically erected in high-altitude, open areas and other regions prone to thunderstorms. The photoelectric signal lines on these towers, including antenna monitoring, navigation light control, and microwave transmission lines, are highly susceptible to direct and induced lightning strikes. Especially during seasons with frequent severe convective weather, if signal cables lack effective physical fixation and electrical isolation protection before entering the equipment room, lightning surges will travel directly along the lines, not only instantly damaging the precision electronic equipment at the back end and causing broadcast interruptions, but also potentially causing secondary short circuits or grounding faults due to cable swaying or loosening, seriously threatening the safe broadcasting of television and the safety of personnel and equipment. Therefore, lightning-proof photoelectric signal isolation protection devices are necessary to ensure stable signal transmission and protection.

[0003] Existing optoelectronic signal isolation and protection devices typically employ rigid clamping methods such as bolt tightening or cable tie binding for cable fixing. These clamping units lack elastic buffering and adaptive adjustment capabilities with respect to the tower's inner wall. This results in an inability to provide uniform and appropriate clamping force when dealing with communication cables of varying diameters and quantities. Excessive tightness can damage the cable insulation and internal fiber core, while excessive looseness can lead to displacement and loosening under tower wind vibration or thermal expansion and contraction. Furthermore, in the event of lightning strikes or severe weather conditions, this rigid fixing structure, lacking flexible buffering, struggles to maintain stable cable positioning. This significantly reduces the reliability of the connection between the front-end surge protection module and the back-end core isolation module, failing to meet the cable safety fixing requirements under complex tower operating conditions.

[0004] Therefore, the applicant proposes a lightning protection photoelectric signal isolation protection device for broadcast television transmission towers to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a lightning protection photoelectric signal isolation protection device for broadcast television transmission towers, in order to solve the problems that existing photoelectric signal isolation protection devices mostly use rigid clamps for cable fixing, which lack elastic buffering and adaptive adjustment capabilities, making it difficult to adapt to different wire diameters, easily causing cable damage or loosening, making the connection between the surge protection module and the core isolation module unreliable, and failing to meet the requirements for safe cable fixing of the signal generation tower.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lightning protection type photoelectric signal isolation protection device for a broadcast television transmission tower, comprising a signal generating tower body and a tower house.

A vertical rod is fixedly connected to one side of the top of the second horizontal rod, and the top of the vertical rod is rotatably connected to the top of the inner cavity of the tower house.

[0008] The top side of the mounting box is provided with a cable pass-through groove, and the inner wall of one side of the tower is respectively equipped with a core isolation module and a surge protection module.

[0009] Furthermore, the top of the vertical rod and the top of the load-bearing rod are both rotatably connected to the top of the inner cavity of the tower house via a rotating shaft.

[0010] Furthermore, the bottom side of the second crossbar and the bottom side of the first crossbar are respectively rotatably connected to the top of the corresponding swing rod via pins.

[0011] Furthermore, displacement grooves are respectively provided on both sides of the vertical rod, and sliders are slidably connected to the inner cavity of the displacement grooves. A side plate is provided in the inner cavity of the vertical rod, and the two ends of the side plate are respectively fixedly connected to one end of the corresponding slider. One side of the side plate is fixedly connected to one side of the corresponding arc-shaped seat.

[0012] Furthermore, a spring damper is fixedly connected to the inner wall of one side of the vertical rod, and one end of the spring damper is fixedly connected to one side of the corresponding side plate.

[0013] Furthermore, doors are rotatably connected to both sides of one outer wall of the tower building via hinges.

[0014] Furthermore, an exhaust vent is provided on one side of the mounting box, and a dustproof net is provided in the inner cavity of the exhaust vent. The outer surface of the dustproof net is fixedly connected to the inner wall of the corresponding exhaust vent.

[0015] Furthermore, a mounting slot is provided on one side of the lower surface of the mounting box. A heat dissipation mechanism is provided in the inner cavity of the mounting slot. The heat dissipation mechanism includes a mounting frame. A straight rod is provided in the inner cavity of the mounting frame. Several main bevel gears are sleeved on the outer surface of the straight rod. Several guide slots are provided on one side of the inner wall of the mounting slot. A fan frame is provided in the inner cavity of the guide slot. A fan blade is provided in the inner cavity of the fan frame. A short rod is fixedly connected to one end of the fan blade.

[0016] Furthermore, the inner cavities of several of the guide slots are all connected to the inner cavity of the mounting box.

[0017] Furthermore, a drive motor is fixedly connected to one side of the mounting frame, one end of the straight rod is rotatably connected to the inner wall of the mounting frame via a rotating shaft, and the other end of the straight rod is fixedly connected to the output shaft of the drive motor through a bushing penetrating the side wall of the mounting frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By setting up the cable harness mechanism and combining it with the elastic buffer of the spring damper, the cable can be flexibly and adaptively clamped, avoiding damage to the insulation layer or loosening due to wind vibration caused by rigid fixation. The buffer structure formed by the arc-shaped seat and the spring damper can dynamically compensate when the cable sways, maintain the connection stability between the surge protection module and the core isolation module, and ensure the protection effect under severe weather conditions.

[0020] By setting up a heat dissipation mechanism, the drive motor rotates the straight rod, causing the main bevel gear and the secondary bevel gear to mesh and drive the short rod and fan blades to rotate synchronously, forming forced convection. Combined with the exhaust channel, an efficient heat dissipation channel is constructed to promptly dissipate the heat generated by the core isolation module and surge protection module and other electronic components in the tower room. This effectively avoids high temperature accumulation that could lead to module performance degradation or failure, ensuring the stable operation of the lightning protection photoelectric signal isolation protection device under continuous high load conditions and extending the overall service life of the equipment.

[0021] By using the outer frame mechanism, the mounting box provides the cable management mechanism with an independent operating space that is connected to the inner cavity of the tower. This allows the cables to be orderly introduced into the cable guide slots of the guide rails and accurately guided into the wire guide slots of the guide rails, preventing the cables from becoming tangled or interfering with the core isolation module and surge protection module when entering the tower. At the same time, the mounting box serves as the load-bearing base for the cable management mechanism, providing stable support and external protection for its internal moving parts. It effectively isolates the cable management mechanism from the erosion caused by rainwater, dust, and mechanical impacts, ensuring that the arc-shaped clamps and arc-shaped seats are not affected by the external environment during the cable clamping process, and maintaining the long-term reliability of the flexible adaptive clamping function.

[0034] As attached Figure 1 To be continued Figure 8 As shown:

[0035] Example 1:

[0036] This invention provides a lightning protection photoelectric signal isolation protection device for a broadcast television transmission tower, including a signal generating tower body 1 and a tower room 3. The bottom of the signal generating tower body 1 is fixedly connected to the top of the tower room 3. An outer frame mechanism 2 is fixedly connected to one side of the top of the tower room 3. The outer frame mechanism 2 includes a mounting box 201. The inner cavity of the mounting box 201 is connected to the inner cavity of the tower room 3. A wire harness mechanism 5 is provided in the inner cavity of the mounting box 201. The wire harness mechanism 5 includes a slide rail 501. One side of the slide rail 501 is fixedly connected to one side of the inner wall of the tower room 3. A toothed plate 504 is slidably connected to the inner cavity of the slide rail 501. An electric push rod 502 is fixedly connected to one side of the inner wall of the tower room 3. A piston rod 503 is fixedly connected to the output end of the electric push rod 502. One end of the piston rod 503 away from the electric push rod 502 is fixedly connected to one end of the toothed plate 504. A wire through groove 516 is opened on one side of the top of the slide rail 501.

[0037] Below the slide rail 501 and along the horizontal direction of the slide rail 501, there are several arc-shaped clamps 513. One side of the arc-shaped clamp 513 is fixedly connected to the inner wall of the tower 3. The other side of the arc-shaped clamp 513 is provided with an arc-shaped seat 512. One side of the arc-shaped seat 512 is provided with a vertical rod 509. One side of the vertical rod 509 is fixedly connected with a swing rod 508. The top two sides of the swing rod 508 are respectively rotatably connected with a second horizontal rod 510 and a first horizontal rod 507. One side of the top of the first horizontal rod 507 is fixedly connected with a force-bearing rod 505. The top of the force-bearing rod 505 is rotatably connected to the top of the inner cavity of the tower 3. The outer surface of the force-bearing rod 505 is sleeved with a transmission gear 506. The transmission gear 506 meshes with a toothed plate 504. One side of the top of the second horizontal rod 510 is fixedly connected with a vertical rod 509. The top of the vertical rod 509 is rotatably connected to the top of the inner cavity of the tower 3.

[0038] The top side of the mounting box 201 is provided with a cable pass-through groove 202, and the inner wall of one side of the tower 3 is respectively equipped with a core isolation module 7 and a surge protection module 8.

[0039] The top of the vertical rod 509 and the top of the load-bearing rod 505 are both rotatably connected to the top of the inner cavity of the tower 3 via a rotating shaft.

[0040] Working principle: First, the operator passes the communication cable of the signal generating tower 1 through the cable passage 202 opened at the top of the mounting box 201, allowing it to enter the inner cavity of the mounting box 201 and connect it with the core isolation module 7 and surge protection module 8 inside the tower 3. Then, the cable passes through the wire passage 516 opened on one side of the top of the slide rail 501, and sequentially passes through the space formed by the inner arc surface of the arc clamp 513 and the inner arc surface of the corresponding arc seat 512. After all the cables are placed, the operator activates the electric push rod 502 to move the piston rod 503, causing the piston rod 503 to push the toothed plate 504 to slide in the inner cavity of the slide rail 501. The displacement of the toothed plate 504 drives the transmission gear 506 that meshes with it to rotate the force rod 505. The rotation of the force rod 505 drives the corresponding crossbar 507 to rotate, and the swing rod is driven by the pin shaft. 508 performs a trajectory-controlled rotation. Under the combined action of the vertical rod 509 and the horizontal rod 510, the swing rod 508 drives the arc-shaped seat 512 to approach the arc-shaped clamp 513 and physically compress the wire. When the wire is in contact with the inner arc surface of the arc-shaped seat 512, the arc-shaped seat 512 is pressed and displaced into the inner cavity of the corresponding vertical rod 509 and compresses the spring damper 515, thereby ensuring the clamping force while avoiding rigid damage to the wire. When the signal tower 1 is subjected to lightning interference, the broadcast signal first enters the surge protection module 8 and then enters the core isolation module 7. After stabilization, it is transmitted outward to achieve photoelectric signal isolation protection. At the same time, the drive motor 602 drives the straight rod 603 to rotate, so that the main bevel gear 604 drives the secondary bevel gear 605 and the short rod 606 to drive the fan blade 607 to rotate, so that the heat inside the tower 3 is discharged through the exhaust channel 203.

[0041] This solution, through the configuration of slide rail 501, toothed plate 504, transmission gear 506, force-bearing rod 505, horizontal bar 1 507, swing rod 508, vertical rod 509, horizontal bar 2 510, arc-shaped clamp 513, and arc-shaped seat 512, combined with the elastic buffering effect of spring damper 515, achieves flexible and adaptive clamping of cables. This effectively solves the problem of existing rigid clamping methods easily damaging the cable insulation layer or loosening under wind vibration, ensuring stable fixation of cables of different diameters. Addressing the deficiency of traditional devices lacking elastic buffering, which reduces the reliability of the connection between surge protection module 8 and core isolation module 7, the arc-shaped seat 512 and spring damper 515 form a... The flexible buffer structure provides dynamic compensation when the cable is subjected to external force and vibration, maintaining the stability of the connection between the cable and the module, and ensuring the protection effect of the lightning protection photoelectric signal isolation protection device under severe weather conditions. In addition, the linkage heat dissipation component composed of drive motor 602, straight rod 603, main bevel gear 604, secondary bevel gear 605, short rod 606 and fan blade 607 in heat dissipation mechanism 6, together with exhaust channel 203, forms an efficient heat dissipation channel, which promptly dissipates the heat generated by the operation of electronic components in tower 3, avoiding the impact of high temperature on the performance of core isolation module 7 and surge protection module 8, and further improving the overall operational reliability and service life of the device.

[0042] Example 2:

[0043] This embodiment is basically the same as the previous embodiment, except that the bottom side of the second crossbar 510 and the bottom side of the first crossbar 507 are respectively rotatably connected to the top of the corresponding swing rod 508 through a pin.

[0044] The vertical rod 509 has displacement grooves 517 on both sides. The inner cavity of the displacement groove 517 is slidably connected to a slider 511. The inner cavity of the vertical rod 509 is provided with a side plate 514. The two ends of the side plate 514 are fixedly connected to one end of the corresponding slider 511, and one side of the side plate 514 is fixedly connected to one side of the corresponding arc-shaped seat 512.

[0045] A spring damper 515 is fixedly connected to the inner wall of one side of the vertical rod 509, and one end of the spring damper 515 is fixedly connected to one side of the corresponding side plate 514.

[0046] Doors 4 are hinged to both sides of one side of the outer wall of tower 3.

[0047] An exhaust channel 203 is provided on one side of the mounting box 201. A dustproof net 204 is provided in the inner cavity of the exhaust channel 203. The outer surface of the dustproof net 204 is fixedly connected to the inner wall of the corresponding exhaust channel 203.

[0048] Working Principle: The tops of the vertical rod 509 and the top of the force-bearing rod 505 are rotatably connected to the top of the inner cavity of the tower 3 via rotating shafts. When the cable management mechanism 5 is running, the force-bearing rod 505 rotates around its shaft connected to the top of the inner cavity of the tower 3 under the drive of the transmission gear 506. Simultaneously, the vertical rod 509, serving as the other support point of the swing rod 508, also rotates synchronously around its shaft connected to the top of the inner cavity of the tower 3. This allows the swing rod 508, the first horizontal rod 507, the second horizontal rod 510, the force-bearing rod 505, and the vertical rod 509 to form a stable double-rocker linkage system. This ensures that the movement trajectory of the arc-shaped seat 512 is precisely controllable as it approaches the arc-shaped clamp 513, preventing jamming or deviation due to unilateral force and ensuring uniform pressure on the cable. As a result, by means of a pin-connected bottom side of the second horizontal bar 510 and the bottom side of the first horizontal bar 507 to the top of the corresponding swing rod 508, when the force rod 505 drives the first horizontal bar 507 to rotate, the first horizontal bar 507 transmits power to the top of the swing rod 508 through the pin. At the same time, the second horizontal bar 510 provides constraint and guidance to the other side of the top of the swing rod 508 through another pin, so that the swing rod 508 can only swing along a preset plane under the constraint of the two pins instead of swaying randomly. This achieves the effect of accurately converting the rotational motion into the linear approximation action of the arc seat 512, improving the transmission efficiency and response accuracy of the wire harness mechanism 5. Displacement slots 517 are respectively opened on both sides of the vertical bar 509. The inner cavity of the vertical rod 509 is slidably connected to a slider 511. The inner cavity of the vertical rod 509 is provided with a side plate 514. Both ends of the side plate 514 are fixedly connected to one end of the corresponding slider 511. One side of the side plate 514 is fixedly connected to one side of the corresponding arc-shaped seat 512. When the arc-shaped seat 512 is subjected to the reaction force of the cable, this force is transmitted through the arc-shaped seat 512 to the side plate 514. The side plate 514 drives the sliders 511 at both ends to slide smoothly in the vertical direction within the displacement grooves 517 on both sides of the vertical rod 509. This allows the arc-shaped seat 512 to generate a controlled axial displacement relative to the vertical rod 509, providing a precise guiding path for the compression deformation of the spring damper 515, preventing the arc-shaped seat 512 from tilting or jamming during compression, and ensuring the flexible buffering function. The effect achieved is achieved by fixing a spring damper 515 to the inner wall of one side of the vertical rod 509. One end of the spring damper 515 is fixedly connected to one side of the corresponding side plate 514. When the arc-shaped seat 512 is displaced into the inner cavity of the vertical rod 509 due to cable compression, the side plate 514 moves synchronously and compresses the spring damper 515. The spring damper 515 generates an elastic reaction force proportional to the displacement and acts on the side plate 514. This force is then fed back to the cable surface through the arc-shaped seat 512. Under the premise that the electric push rod 502 provides a constant driving force, the clamping force required for cables of different diameters can be automatically adapted. This avoids damage to the cable insulation layer and fiber core due to excessive tightness, and also prevents the cable from loosening due to wind vibration due to excessive looseness, thus achieving a flexible and adaptive clamping effect.

[0049] Example 3:

[0050] This embodiment is basically the same as the previous embodiment, except that a mounting slot 205 is provided on one side of the lower surface of the mounting box 201. A heat dissipation mechanism 6 is provided in the inner cavity of the mounting slot 205. The heat dissipation mechanism 6 includes a mounting frame 601. A straight rod 603 is provided in the inner cavity of the mounting frame 601. Several main bevel gears 604 are sleeved on the outer surface of the straight rod 603. Several guide slots 608 are provided on one side of the inner wall of the mounting slot 205. A fan frame is provided in the inner cavity of the guide slot 608. A fan blade 607 is provided in the inner cavity of the fan frame. A short rod 606 is fixedly connected to one end of the fan blade 607. A secondary bevel gear 605 is fixedly connected to one end of the short rod 606 through the side wall of the fan frame. The secondary bevel gear 605 meshes with the corresponding main bevel gear 604.

[0051] The inner cavities of several guide slots 608 are all connected to the inner cavity of the mounting box 201.

[0052] A drive motor 602 is fixedly connected to one side of the mounting frame 601. One end of the straight rod 603 is rotatably connected to the inner wall of the mounting frame 601 via a rotating shaft. The other end of the straight rod 603 is fixedly connected to the output shaft of the drive motor 602 through a bushing that passes through the side wall of the mounting frame 601.

[0053] Working principle: Doors 4 are hinged to both sides of the outer wall of tower 3. When maintenance personnel need to inspect, debug, or replace the core isolation module 7, surge protection module 8, or cable management mechanism 5 inside tower 3, they can directly open door 4 around the hinges to enter the interior of tower 3. After the work is completed, closing door 4 restores tower 3 to its closed and protected state. This achieves convenient daily maintenance while effectively isolating external rainwater, dust, and small animals, ensuring a safe and stable operating environment for the electronic components inside tower 3. (The last sentence appears to be incomplete and possibly refers to a different system.) The system includes an exhaust channel 203, with a dustproof mesh 204 installed inside. The outer surface of the dustproof mesh 204 is fixedly connected to the inner wall of the corresponding exhaust channel 203. When the heat dissipation mechanism 6 is running, the airflow generated by the rotating fan blades 607 carries heat from the tower 3 and the installation box 201 outward through the exhaust channel 203. Simultaneously, the dustproof mesh 204 intercepts and filters dust particles in the incoming and outgoing airflow, achieving efficient heat dissipation while preventing external dust from flowing back into the installation box 201 and contaminating the core isolation module 7 and surge protection module 8, thus balancing heat dissipation performance and... The equipment's cleanliness protection is achieved through a mounting groove 205 on one side of the lower surface of the mounting box 201. A heat dissipation mechanism 6 is installed within the inner cavity of the mounting groove 205. The heat dissipation mechanism 6 includes a mounting frame 601. A straight rod 603 is installed within the inner cavity of the mounting frame 601. Several main bevel gears 604 are sleeved on the outer surface of the straight rod 603. Several guide grooves 608 are opened on one inner wall of the mounting groove 205. A fan frame is installed within the inner cavity of the guide groove 608, and a fan blade 607 is installed within the inner cavity of the fan frame. One end of the fan blade 607 is fixedly connected to a short rod 606, and one end of the short rod 606... A secondary bevel gear 605 is fixedly connected through the side wall of the fan frame. The secondary bevel gear 605 meshes with the corresponding main bevel gear 604. When the drive motor 602 starts, the straight rod 603 drives all the main bevel gears 604 to rotate synchronously. Each main bevel gear 604 drives the corresponding secondary bevel gear 605 and the short rod 606, so that multiple fan blades 607 rotate and deliver air simultaneously in their respective guide slots 608. This achieves the effect of using a single power source to achieve multi-point uniform heat dissipation, avoids local heat accumulation inside the tower 3, and ensures that the core isolation module 7 and surge protection module 8 are always within a suitable operating temperature range.
