[0014] Furthermore, the method for using the optoelectronic combination cable installation device for bridge and culvert communication comprises the following steps:

[0015] S1: Place the cable between the profile plate and the contact plate, then rotate the threaded rod, the threaded rod drives the profile plate to descend, the profile plate and the contact plate will bend and clamp the cable to prevent the cable from slipping when the movable block drives the cable to move, then start the drive motor, the drive motor drives the shaft to rotate, the shaft drives the rod to rotate under the action of the pulley and the synchronous belt, the rod drives the roller to rotate, the roller drives several round rods to rotate, the round rod will contact the gap between the tooth plates during the rotation process, and push the movable block to move, because the installation box will encounter obstacles during the welding process, so the installation box will have many bends, when the roller passes through the bend, a larger angle and a smaller angle will be generated between the tooth plates, at this time the round rod close to the smaller angle will contact the tooth plate at the bend, so that the device can continue to move;

[0016] S2: During the movement of the movable block, the rotating wheel will rotate along the inner wall of the strip limiting groove, and the rotating wheel will effectively limit the movable block to ensure that the movable block can move at the center position in the installation box. When the movable block moves to the curved area of ​​the installation box, due to the angle problem, the strip limiting groove in the movable block will have a depth deviation. Since the telescopic spring is normally in a compressed state, the telescopic spring will be appropriately lengthened when the rotating wheel reaches the curved area, so that the rotating wheel can always be close to the strip limiting groove, thereby ensuring the stable movement of the movable block;

[0017] S3: After the cable is fixed and tightened, it will be tightly attached to the hollow rubber sleeve. When a vehicle passes through the bridge culvert, it will vibrate. The vibration will affect the cables in the installation box and cause the cables to vibrate. The cables will drive the hollow rubber sleeve to shake up and down. When the cables shake up and down, the friction force will drive the hollow rubber sleeve to move upward. At this time, the adaptive spring will produce a buffer.

[0018] S4: After the movable block pulls the cable through the L-shaped support plate, the L-shaped support plate is manually pressed, and the L-shaped support plate moves into the installation box and passes through the sliding slot. At this time, the support spring is compressed and deformed. Since the cable has just passed the L-shaped support plate, the cable is nearly horizontal due to the short distance and will not contact the L-shaped support plate. When the cable distance is long, the cable will droop downward due to the action of gravity. At this time, the cable just falls on the L-shaped support plate. At this time, multiple L-shaped support plates in the installation box will provide support for the cable to prevent the cable from drooping for a long time, causing cracks in the cable skin and contacting the installation box.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention is a photoelectric combined cable installation device for bridge and culvert communication. During use, the cable is placed between the profile plate and the contact plate, and then the threaded rod is rotated. The threaded rod drives the profile plate to descend. The profile plate and the contact plate bend and clamp the cable. Since the cable is relatively thick, the bent cable will improve its clamping effect to prevent the cable from slipping when the movable block drives the cable to move. Then the drive motor is started, and the drive motor drives the shaft to rotate. The shaft drives the rotating rod to rotate under the action of the pulley and the synchronous belt. The rotating rod drives the rotating roller to rotate, and the rotating roller drives a plurality of The circular rod rotates, and the circular rod contacts the gap between the tooth plates during the rotation process, and pushes the movable block to move. Since the installation box will encounter obstacles during the welding process, the installation box will have many bends. When the roller passes through the bend, a larger angle and a smaller angle will be generated between the tooth plates. At this time, the circular rod close to the smaller angle will contact the tooth plate at the bend, so that the device can continue to move, improving the flexibility and adaptability of the device. Under the pull of the movable block, the cable will pass through the installation box more smoothly, improving the installation efficiency of the cable;

[0021] (2) In the optoelectronic combined cable installation device for bridge and culvert communication of the present invention, during the movement of the movable block, the rotating wheel will rotate along the inner wall of the strip limiting groove, and the rotating wheel will effectively limit the movable block to ensure that the movable block can move to the center position in the installation box. When the movable block moves to the bend area of ​​the installation box, due to the angle problem, the strip limiting groove in the movable block will have a depth deviation. Since the telescopic spring is normally in a compressed state, the telescopic spring will be appropriately lengthened when the rotating wheel reaches the bend area, so that the rotating wheel can always be close to the strip limiting groove, thereby ensuring the stable movement of the movable block and avoiding the phenomenon of the movable block moving unsmoothly;

[0022] (3) The present invention provides a photoelectric combination cable installation device for bridge and culvert communication. After the cable is fixed and tightened, the cable will be tightly attached to the hollow rubber sleeve. When a vehicle passes through the bridge or culvert, vibration will occur. The vibration will affect the cable in the installation box and cause the cable to vibrate. The cable will drive the hollow rubber sleeve to shake up and down. When the cable shakes up and down, it will drive the hollow rubber sleeve to move upward under the action of friction. At this time, the adaptive spring will produce a buffer to prevent the cable from wearing the cable sheath during the sliding friction with the hollow rubber sleeve. When the cable moves left and right, the cable will drive the hollow rubber sleeve to rotate, and at the same time, it can effectively avoid the sliding friction between the cable and the hollow rubber sleeve, effectively protect the cable sheath and increase the service life of the cable;

[0023] (4) The present invention provides a photovoltaic combined cable installation device for bridge culvert communication. After the movable block pulls the cable through the L-shaped support plate, the L-shaped support plate is manually pressed down, and the L-shaped support plate moves into the installation box and passes through the sliding groove. At this time, the support spring is compressed and deformed. Since the cable has just passed the L-shaped support plate, the cable is nearly horizontal due to the short distance and will not contact the L-shaped support plate. When the cable is long, the cable will droop downward due to the action of gravity. At this time, the cable just falls on the L-shaped support plate. At this time, multiple L-shaped support plates in the installation box will provide support for the cable, avoiding the cable from drooping for a long time, causing the cable skin to crack and contact the installation box. The installation box will be in rainy weather. Rust will occur, affecting the quality of the cable and the signal transmission. After the L-shaped support plate passes through the sliding groove, the locking spring is normally in a compressed state. At this time, the triangular locking block will leave the rectangular groove under the elastic force of the locking spring. After releasing your hand, the L-shaped support plate will be pulled back under the elastic force of the support spring. At this time, the triangular locking block will be close to the inner wall of the strip mounting groove and the L-shaped support plate will be fixed in the mounting box. When the cable needs to be replaced, the two circular connecting rods are moved to make the two circular connecting rods close to each other. At this time, the cross slider will push the two triangular locking blocks into the rectangular groove. At this time, the L-shaped support plate will leave the cable, making it easier to pull out the cable for quick replacement.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 - Figure 8 As shown, the present invention is a photoelectric combined cable installation device for bridge and culvert communication, comprising an installation box 1, a movable block 2 is arranged in the installation box 1, a plurality of tooth plates 3 are fixedly installed on the inner wall of the bottom of the installation box 1, an installation cavity 4 is opened in the movable block 2, and further comprising:

[0038] The movable mechanism 5 includes a driving motor 501 fixedly installed in the installation cavity 4, a rotating shaft 502 is fixedly installed on the output shaft of the driving motor 501, the right end of the rotating shaft 502 is rotatably connected to the installation cavity 4, a connecting groove is provided on the inner wall of the bottom of the installation cavity 4, a rotating rod 503 is rotatably installed on the movable block 2, and pulleys 504 are fixedly sleeved on the rotating rod 503 and the rotating shaft 502, and synchronous belts 505 are sleeved on the two pulleys 504. The synchronous belts 505 run through the connecting rod 503. A connecting groove, a rotating roller 506 is fixedly sleeved on the rotating rod 503, and a plurality of circular grooves 507 are opened on the rotating roller 506. A plurality of movable springs 508 are fixedly installed on the inner walls of the mutually close sides of the plurality of circular grooves 507, and a plurality of circular rods 509 are fixedly installed on the ends of the plurality of movable springs 508 which are far away from each other. The plurality of circular rods 509 extend into the plurality of circular grooves 507 and are slidably connected with the plurality of circular grooves 507, and the plurality of circular rods 509 are meshed with the plurality of tooth plates 3.

[0039] As shown Figure 3 in the figure, hollow boxes 510 are fixedly installed on the left and right sides of the movable block 2 respectively. Telescopic springs 511 are fixedly installed on the inner walls of the two hollow boxes 510 close to each other. Mounting brackets 512 are fixedly installed at the ends of the two telescopic springs 511 away from each other. The two mounting brackets 512 extend to the outside of the two hollow boxes 510 respectively and are slidably connected to the two hollow boxes 510. Rotating wheels 513 are rotatably installed in the two mounting brackets 512 respectively.

[0040] During the movement of the movable block 2, at this time, the rotating wheel 513 will perform a rotational movement along the inner wall of the strip-shaped limiting groove 605. The rotating wheel 513 effectively limits the movable block 2, ensuring that the movable block 2 can move at the central position in the installation box 1.

[0041] As shown Figure 2 and Figure 3 in the figure, a fixing mechanism 6 is arranged on the front surface of the movable block 2. The fixing mechanism 6 includes a U-shaped plate 601 arranged on the front surface of the movable block 2. A contact plate 602 is fixedly installed on the front surface of the movable block 2. A limiting plate 606 is fixedly installed at the bottom of the U-shaped plate 601. The limiting plate 606 penetrates through the contact plate 602 and is slidably connected to the contact plate 602. A threaded rod 603 is rotatably installed on the U-shaped plate 601. The threaded rod 603 penetrates through the U-shaped plate 601 and the contact plate 602. The threaded rod 603 is threadedly connected to the contact plate 602. Strip-shaped limiting grooves 605 are respectively formed on the left inner wall and the right inner wall of the installation box 1. The two rotating wheels 513 respectively extend into the two strip-shaped limiting grooves 605 and are respectively in contact with the two strip-shaped limiting grooves 605.

[0042] When the movable block 2 moves to the curved area of the installation box 1, at this time, due to the angle problem, the depth of the strip-shaped limiting groove 605 in the movable block 2 will deviate. Since the telescopic spring 511 is normally in a compressed state, when the rotating wheel 513 reaches the curved area, the telescopic spring 511 will elongate appropriately, so that the rotating wheel 513 can always be in close contact with the strip-shaped limiting groove 605, thereby ensuring the stable movement of the movable block 2 and avoiding the phenomenon of the movable block 2 moving in a stuck and unsmooth manner.

[0043] As shown Figure 4As shown, a plurality of anti-wear mechanisms 7 are arranged in the installation box 1, and the anti-wear mechanism 7 includes a T-shaped round rod 701 fixedly installed on the inner wall of the top of the installation box 1, and two adaptive springs 702 are sleeved on the T-shaped round rod 701, and circular plates 703 are fixedly installed at the ends of the two adaptive springs 702 close to each other, respectively. The T-shaped round rod 701 penetrates the two circular plates 703 and is slidably connected to the two circular plates 703, and the ends of the two adaptive springs 702 away from each other are fixedly connected to the installation box 1 and the T-shaped round rod 701, respectively. A hollow rubber sleeve 704 is rotatably installed at the ends of the two circular plates 703 close to each other, and the T-shaped round rod 701 penetrates the hollow rubber sleeve 704 and is slidably connected to the hollow rubber sleeve 704.

[0044] After the cable is fixed and tightened, the cable will be tightly attached to the hollow rubber sleeve 704. When a vehicle passes through a bridge or a culvert, vibration will be generated. The vibration will affect the cable in the installation box 1 and cause the cable to vibrate. The cable will drive the hollow rubber sleeve 704 to shake up and down. When the cable shakes up and down, it will drive the hollow rubber sleeve 704 to move upward under the action of friction. At this time, the adaptive spring 702 will produce a buffer to prevent the cable from wearing the cable skin during the sliding friction with the hollow rubber sleeve 704. When the cable moves left and right, the cable will drive the hollow rubber sleeve 704 to rotate, and at the same time, it can also effectively avoid the sliding friction between the cable and the hollow rubber sleeve 704, effectively protect the cable skin and increase the service life of the cable.

[0045] like Figure 5 and Figure 7 As shown, two supporting mechanisms 8 are arranged on the installation box 1, and the supporting mechanism 8 includes an L-shaped supporting plate 801 slidably installed on the installation box 1, and a supporting spring 802 is fixedly installed on the right inner wall of the L-shaped supporting plate 801, and the left end of the supporting spring 802 is fixedly connected to the installation box 1. A sliding groove 803 is opened on the installation box 1, and the L-shaped supporting plate 801 extends into the sliding groove 803 and is slidably connected to the sliding groove 803.

[0046] After the movable block 2 pulls the cable through the L-shaped support plate 801 , the L-shaped support plate 801 is manually pressed down, and the L-shaped support plate 801 moves into the installation box 1 and passes through the sliding groove 803 .

[0047] like Figure 6 and Figure 7 As shown, a strip-shaped mounting groove 804 is provided on the sliding groove 803, and two rectangular grooves 805 are provided in the L-shaped support plate 801. Locking springs 806 are fixedly installed on the inner walls of the two rectangular grooves 805 that are close to each other, and triangular locking blocks 807 are fixedly installed on the ends of the two locking springs 806 that are away from each other. The ends of the two triangular locking blocks 807 that are away from each other are in contact with the mounting box 1 respectively, and the two triangular locking blocks 807 are slidably connected to the two rectangular grooves 805 respectively.

[0048] The cable has been hanging for a long time, causing cracks in the cable sheath and contacting the installation box 1. The installation box 1 will rust in rainy weather, affecting the quality of the cable and the signal transmission. After the L-shaped support plate 801 passes through the sliding groove 803, since the locking spring 806 is normally in a compressed state, the triangular locking block 807 will leave the rectangular groove 805 under the elastic force of the locking spring 806.

[0049] like Figure 7 As shown, unlocking springs 808 are fixedly installed on the front inner wall and the back inner wall of the strip mounting groove 804, and cross sliders 809 are fixedly installed on the ends of the two unlocking springs 808 close to each other. Two rectangular sliding grooves 810 are respectively opened on the top inner wall and the bottom inner wall of the strip mounting groove 804, and the tops and bottoms of the two cross sliders 809 extend into a plurality of rectangular sliding grooves 810 and are respectively slidably connected with the plurality of rectangular sliding grooves 810, and circular connecting rods 811 are fixedly installed on the left sides of the two cross sliders 809.

[0050] When the cable needs to be replaced, the two circular connecting rods 811 are moved closer to each other, and the cross slider 809 pushes the two triangular locking blocks 807 into the rectangular groove 805. At this time, the L-shaped support plate 801 will leave the cable, making it easier to pull out the cable for quick replacement.

[0051] A method of using a photoelectric combination cable installation device for bridge and culvert communication is as follows:

[0052] During use, the cable is placed between the profile plate 601 and the contact plate 602, and then the threaded rod 603 is rotated. The threaded rod 603 drives the profile plate 601 to descend, and the profile plate 601 and the contact plate 602 bend and clamp the cable. Since the cable is relatively thick, the bent cable will improve its clamping effect to prevent the cable from slipping when the movable block 2 drives the cable to move. Then the drive motor 501 is started, and the drive motor 501 drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the rotating rod 503 to rotate under the action of the pulley 504 and the synchronous belt 505. The rotating rod 503 drives the rotating roller 506 to rotate, and the rotating roller 506 drives several circular rods 509 to rotate. The circular rods 509 will contact the gap between the tooth plates 3 during the rotation process and push the movable block 2 to move. Since the installation box 1 will encounter obstacles during the welding process, the installation box 1 will have many bends. When the roller 506 passes through the bend, a large gap will be generated between the tooth plates 3. Angle and a smaller angle, at this time, the circular rod 509 close to the smaller angle will contact the tooth plate 3 at the bend, so that the device can continue to move, improving the flexibility and adaptability of the device movement, and the cable will pass through the installation box 1 more smoothly under the pulling of the movable block 2, thereby improving the installation efficiency of the cable; during the movement of the movable block 2, the rotating wheel 513 will rotate along the inner wall of the strip limiting groove 605, and the rotating wheel 513 will effectively limit the movable block 2 to ensure that the movable block 2 can move to the center position in the installation box 1. When the movable block 2 moves to the bend area of ​​the installation box 1, due to the angle problem, the strip limiting groove 605 in the movable block 2 will have a depth deviation. Since the telescopic spring 511 is normally in a compressed state, when the rotating wheel 513 reaches the bend area, the telescopic spring 511 will be appropriately lengthened, so that the rotating wheel 513 can always be close to the strip limiting groove 605, thereby ensuring the stable movement of the movable block 2 and avoiding the phenomenon of the movable block 2 moving jamming and not smooth;

[0053] After the cable is fixed and tightened, the cable will be tightly attached to the hollow rubber sleeve 704. When a vehicle passes through a bridge or a culvert, vibration will occur. The vibration will affect the cable in the installation box 1 and cause the cable to vibrate. The cable will drive the hollow rubber sleeve 704 to shake up and down. When the cable shakes up and down, it will drive the hollow rubber sleeve 704 to move upward under the action of friction. At this time, the adaptive spring 702 will produce a buffer to prevent the cable from wearing the cable skin during the sliding friction with the hollow rubber sleeve 704. When the cable moves left and right, the cable will drive the hollow rubber sleeve 704 rotates, and at the same time, it can effectively avoid sliding friction between the cable and the hollow rubber sleeve 704, effectively protect the cable skin and increase the service life of the cable; after the movable block 2 pulls the cable through the L-shaped support plate 801, the L-shaped support plate 801 is manually pressed, and the L-shaped support plate 801 moves into the installation box 1 and passes through the sliding groove 803. At this time, the support spring 802 is compressed and deformed. Since the cable has just passed the L-shaped support plate 801, the cable is nearly horizontal due to the short distance and will not contact the L-shaped support plate 801. When the cable distance is long, the cable will Due to the effect of gravity, the cable will droop downward, and at this time the cable will just fall onto the L-shaped support plate 801. At this time, multiple L-shaped support plates 801 in the installation box 1 will provide support for the cable to prevent the cable from drooping for a long time, causing cracks in the cable skin and contacting the installation box 1. The installation box 1 will rust in rainy weather, affecting the quality of the cable and the signal transmission. After the L-shaped support plate 801 passes through the sliding groove 803, since the locking spring 806 is normally in a compressed state, the triangular lock block 807 will leave under the elastic force of the locking spring 806. Rectangular groove 805, after releasing your hand, the L-shaped support plate 801 will be pulled back under the elastic force of the support spring 802, and the triangular locking block 807 will be close to the inner wall of the strip installation groove 804 and fix the L-shaped support plate 801 through the installation box 1. When the cable needs to be replaced, the two circular connecting rods 811 are moved to make the two circular connecting rods 811 close to each other. At this time, the cross slider 809 will push the two triangular locking blocks 807 into the rectangular groove 805. At this time, the L-shaped support plate 801 will leave the cable, so it is easier to pull out the cable for quick replacement.

7. A method for using a photoelectric combination cable installation device for bridge and culvert communication, using the photoelectric combination cable installation device for bridge and culvert communication as claimed in claim 6, characterized in that: The steps are as follows: S1: The cable is placed between the profile plate (601) and the contact plate (602), and then the threaded rod (603) is rotated. The threaded rod (603) drives the profile plate (601) to descend. The profile plate (601) and the contact plate (602) bend and clamp the cable to prevent the cable from slipping when the movable block (2) drives the cable to move. Then, the drive motor (501) is started. The drive motor (501) drives the rotating shaft (502) to rotate. The rotating shaft (502) drives the rotating rod (503) to rotate under the action of the pulley (504) and the synchronous belt (505). The rotating rod (503) drives The roller (506) rotates, and the roller (506) drives a plurality of circular rods (509) to rotate. During the rotation process, the circular rods (509) contact the gaps between the tooth plates (3) and push the movable block (2) to move. Since the installation box (1) encounters obstacles during the welding process, the installation box (1) will have many bends. When the roller (506) passes through the bends, a larger angle and a smaller angle will be generated between the tooth plates (3). At this time, the circular rod (509) close to the smaller angle will contact the tooth plates (3) at the bend, so that the device can continue to move. S2: During the movement of the movable block (2), the rotating wheel (513) will rotate along the inner wall of the strip limiting groove (605), and the rotating wheel (513) will effectively limit the movable block (2), ensuring that the movable block (2) can move at the center position in the installation box (1). When the movable block (2) moves to the curved area of ​​the installation box (1), due to the angle problem, the strip limiting groove (605) in the movable block (2) will have a depth deviation. Since the telescopic spring (511) is normally in a compressed state, when the rotating wheel (513) reaches the curved area, the telescopic spring (511) will be appropriately lengthened, so that the rotating wheel (513) can always be close to the strip limiting groove (605), thereby ensuring the stable movement of the movable block (2); S3: After the cable is fixed and tightened, the cable will be tightly attached to the hollow rubber sleeve (704). When a vehicle passes through the bridge culvert, vibration will occur. The vibration will affect the cable in the installation box (1) and cause the cable to vibrate. The cable will drive the hollow rubber sleeve (704) to shake up and down. When the cable shakes up and down, the friction force will drive the hollow rubber sleeve (704) to move upward. At this time, the adaptive spring (702) will produce a buffer. S4: After the movable block (2) pulls the cable through the L-shaped support plate (801), the L-shaped support plate (801) is manually pressed, and the L-shaped support plate (801) moves into the installation box (1) and passes through the sliding groove (803). At this time, the support spring (802) is compressed and deformed. Since the cable has just passed the L-shaped support plate (801), the cable is in a nearly horizontal state due to the short distance and will not contact the L-shaped support plate (801). When the cable is long, the cable will droop downward due to the action of gravity. At this time, the cable just falls on the L-shaped support plate (801). At this time, the multiple L-shaped support plates (801) in the installation box (1) provide support for the cable, preventing the cable from drooping for a long time, causing the cable skin to crack and contact the installation box (1).
