[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] like Figure 1-Figure 13As shown, this embodiment proposes a utility pole anti-fall protection device, including a storage box 2 fixed on a utility pole 1, which can be connected to the utility pole 1 by bolts, and the storage box 2 is fixed on one side of the utility pole 1 to store the broken cable 4. The two ends of the movable frame 5 are respectively connected to the rotating wheels 7 through one-way bearings, and the cable 4 is arranged between the two rotating wheels 7.

[0039] A one-way bearing is a bearing that can rotate freely in one direction and is locked in the other direction. By setting the one-way bearing, when the cable 4 moves toward the storage box 2 to achieve the storage of the cable 4, the cable 4 can drive the rotating wheel 7 to rotate. When the cable 4 moves away from the storage box 2, the one-way bearing is set, and the rotating wheel 7 cannot rotate, thereby reducing the possibility of the cable 4 moving outward.

[0040] The storage box 2 is slidably connected to the movable frame 5, and the storage box 2 is fixedly connected to a fixed rod 21 arranged in a horizontal direction. The fixed rod 21 and the movable frame 5 are slidably connected, and the movable frame 5 can only slide along the length direction of the fixed rod 21. The compression spring 22 is sleeved on the fixed rod 21, and the left end of the compression spring 22 is connected to the storage box 2, and the right end of the compression spring 22 is connected to the movable frame 5.

[0041] In the initial state, when the movable frame 5 is located in the storage box 2, the compression spring 22 is in a compressed state. The elastic force of the compression spring 22 can move the movable frame 5 away from the storage box 2, thereby allowing the movable frame 5 to move outward, so that the clamping position of the pulling cable 4 is at a sufficient distance from the utility pole 1, thereby facilitating the subsequent pulling of the cable 4.

[0042] The movable frame 5 is rotatably connected to a support plate 3 for supporting a cable 4, a cable groove is provided on the upper surface of the support plate 3 to facilitate the placement of the cable 4, the movable frame 5 is connected to a clamping plate 53 that can reciprocate for pulling the cable 4; the movable frame 5 is connected to a motor for driving the clamping plate 53 to move, the movable frame 5 is slidably connected to a conductive block 56 through a small spring, the movable frame 5 is connected to a contact 57 that cooperates with the conductive block 56, and when the conductive block 56 and the contact 57 are in contact, the motor can be controlled to work.

[0043] The utility pole 1 is connected to a solar panel 12, which is used to power the motor. The utility pole 1 can also be connected to an indicator light 11, which can also be used to power the indicator light 11. When the conductive block 56 and the contact 57 are in contact, the indicator light 11 is powered on and lights up, which serves as an auxiliary warning. Alternatively, a battery can be used directly to power the motor.

[0044] The movable frame 5 is slidably connected with an unlocking rod 55 that moves in the horizontal direction. A small spring is sleeved on the unlocking rod 55. One end of the small spring is connected to the unlocking rod 55, and the other end is connected to the movable frame 5. The conductive block 56 is fixedly connected to the unlocking rod 55. When the unlocking rod 55 slides in the horizontal direction, the unlocking rod 55 can drive the conductive block 56 to move. The contact 57 is a conductive structure. When the conductive block 56 moves to contact with the contact 57, the circuit corresponding to the motor forms a complete loop. At this time, the circuit corresponding to the motor is energized and the motor works.

[0045] The support plate 3 is connected to the movable frame 5 through a torsion spring. The elastic force of the torsion spring is much greater than the elastic force of the small spring. In the initial state, under the action of the torsion spring, the support plate 3 is in a horizontal state. The support plate 3 drives the unlocking rod 55 to move, so that the conductive block 56 moves to the side of the contact 57, and the motor is not energized.

[0046] When the cable 4 breaks, the cable 4 sags and drives the support plate 3 to rotate around the movable frame 5, causing the torsion spring to deform. The small spring drives the unlocking rod 55 to move, causing the conductive block 56 to contact the contact 57. When the broken cable 4 is stored, the torsion spring drives the support plate 3 to reset, and the support plate 3 drives the unlocking rod 55 to move, causing the conductive block 56 to move to the side of the contact 57, and the motor is powered off.

[0047] The movable frame 5 is slidably connected with a clamping rod 54 that moves in the vertical direction. The clamping rod 54 is connected to the movable frame 5 through a reset spring. The reset spring is sleeved on the clamping rod 54. One end of the reset spring is connected to the clamping rod 54, and the other end of the reset spring is connected to the movable frame 5. The storage box 2 is provided with a clamping groove for the clamping rod 54 to slide into, and the clamping rod 54 is provided with a limiting groove for the unlocking rod 55 to slide into.

[0048] In the initial state, the support plate 3 moves the unlocking rod 55 into the limiting groove to limit the clamping rod 54. At this time, the conductive block 56 is located on the side of the contact 57, and the unlocking rod 55 moves into the clamping groove to limit the movable frame 5, and the compression spring 22 is in a compressed state. The elastic force of the small spring can move the unlocking rod 55 to the conductive block 56 and the contact 57, and at the same time, the unlocking rod 55 moves out of the limiting groove, and the elastic force of the reset spring can move the clamping rod 54 out of the clamping groove.

[0049] The movable frame 5 is rotatably connected to a reciprocating screw rod 51, which is arranged in a horizontal direction. The output shaft of the motor is connected to the reciprocating screw rod 51, and the reciprocating screw rod 51 is matched with a nut 52. The nut 52 is slidably connected to the movable frame 5, and the nut 52 is slidably connected to a clamping plate 53 that moves toward or away from each other. A first spring is connected between the two clamping plates 53. When the reciprocating screw rod 51 rotates, it can drive the nut 52 to reciprocate in the horizontal direction.

[0050] The reciprocating screw 51 is a screw that can make the nut 52 reciprocate without changing the rotation direction of the main shaft. The reciprocating screw 51 is a form of a three-dimensional cam pair, which is represented by two thread grooves with the same pitch and opposite rotation directions. The two ends are connected by a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the nut 52 placed in the spiral groove to make axial reciprocating motion.

[0051] The movable frame 5 is provided with a slide groove, which includes an inner slide groove 61 and an outer slide groove 62. The right end of the inner slide groove 61 is connected to the outer slide groove 62 through an inclined groove 63, and the left end of the inner slide groove 61 is connected to the outer slide groove 62 through a horizontal groove. The splint 53 is connected to a spring column 58, and the spring column 58 is slidably set in the slide groove.

[0052] The first spring is always in a compressed state. When the spring column 58 slides in the outer slide groove 62, the gap between the two clamping plates 53 is larger than the diameter of the cable 4. When the spring column 58 slides from the inclined groove 63 to the inner slide groove 61, the two clamping plates 53 move inward to clamp the cable 4. At this time, when the spring column 58 moves to the left in the inner slide groove 61, the cable 4 can be pulled.

[0053] The outer slide groove 62 is higher on the left and lower on the right, and the height of the inclined groove 63 is higher than the right end of the outer slide groove 62. The spring column 58 includes a third spring and a sliding column. The sliding column and the clamping plate 53 are slidably connected. The third spring is sleeved on the sliding column. One end of the third spring is connected to the sliding column, and the other end is connected to the clamping plate 53. The third spring is always in a compressed state. Under the elastic force of the third spring, the sliding column is always in contact with the upper surface of the slide groove, so that when the sliding column slides to the lower right end of the outer slide groove 62, it can directly slide into the inclined groove 63 to prevent sliding backward, and then slide into the inner slide groove 61.

[0054] The storage box 2 is fixedly connected with a sliding rod 29 and a guide rod 27 both arranged in vertical directions. The sliding rod 29 is slidably connected with a first rack 25. The guide rod 27 is slidably connected with a second rack 28. The first rack 25 is rotatably connected with a pressure rod 24 that can only rotate downward. The first rack 25 is fixedly connected with a limiting block. The limiting block is in contact with the upper surface of the pressure rod 24. Under the limiting action of the limiting block, the pressure rod 24 can only rotate downward. The second rack 28 is connected with a pull rope, and the other end of the pull rope is connected to the nut 52. The second rack 28 can only slide along the length direction of the guide rod 27.

[0055] The storage box 2 is rotatably connected to a guide wheel 23. When the movable frame 5 moves outward, the right end of the pull rope is driven to move rightward. The pull rope can be hung on the guide wheel 23 to keep the pull rope in a taut state. When the reciprocating screw rod 51 drives the nut 52 to move rightward, the pull rope can drive the second rack 28 to move upward.

[0056] The storage box 2 is rotatably connected to a gear 26, and both ends of the gear 26 are respectively meshed with the first rack 25 and the second rack 28. The second rack 28 is connected to the storage box 2 through a second spring. The second spring is sleeved on the slide bar 29. The lower end of the second spring is connected to the second rack 28, and the upper end is connected to the storage box 2. The length of the second spring is long enough to facilitate the second rack 28 to move a sufficient distance. When the pull rope drives the second rack 28 to rise, the first rack 25 is driven down through the gear 26, and the second spring is compressed.

[0057] A method for using a utility pole anti-fall protection device, using the above utility pole anti-fall protection device, comprises the following steps:

[0058] S1: When the cable 4 breaks, the cable 4 drives the support plate 3 to rotate around the movable frame 5, and the small spring drives the unlocking rod 55 to move, so that the conductive block 56 and the contact 57 are in contact. At this time, the motor is energized, and the reset spring drives the clamping rod 54 to disengage from the clamping slot of the storage box 2, and the compression spring 22 drives the movable frame 5 to move out of the storage box 2;

[0059] S2: The motor drives the reciprocating screw 51 to rotate, the reciprocating screw 51 drives the nut 52 to move, the nut 52 drives the clamping plate 53 to slide, and the spring column 58 slides in the outer slide groove 62. At the same time, the nut 52 drives the second rack 28 to rise through the pull rope, and the second rack 28 drives the first rack 25 to descend through the gear 26. The first rack 25 drives the pressure rod 24 to descend, and the pressure rod 24 presses down the cable 4, so that the cable 4 is bent and enters the storage box 2;

[0060] S3: As the clamping plate 53 continues to move, the spring column 58 slides from the inclined groove 63 into the inner sliding groove 61 to clamp the cable 4. At this time, when the reciprocating screw rod 51 continues to rotate, it drives the clamping plate 53 to move leftward to pull the cable 4 and move the cable 4 into the storage box 2. At this time, the second spring drives the second rack 28 to reset, and the second rack 28 drives the first rack 25 to reset. In this process, the pressure rod 24 rotates around the first rack 25 to pass over the cable 4.

[0061] S4: When the cable 4 is stored, the torsion spring drives the support plate 3 to reset, and the support plate 3 drives the unlocking rod 55 to move to the left, so that the conductive block 56 moves to one side of the contact 57, and the motor is powered off, so that the broken cable 4 is stored in the storage box 2;

[0062] In S4, there are two limit slots on the card rod 54. When the card rod 54 slides into the card slot of the storage box 2, the unlocking rod 55 slides into the limit slot above the card rod 54. When the reset spring drives the card rod 54 to move upward to reset the card rod 54, the limit slot below the card rod 54 is flush with the unlocking rod 55. Therefore, when the unlocking rod 55 moves, it can slide into the limit slot below the card rod 54.

[0063] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
