Description

Technical Field

[0001] This invention relates to the field of foreign object removal devices, specifically a foreign object removal device for the maintenance of power equipment. Background Technology

[0002] With the rapid development of my country's economy, the construction of power equipment is increasing, and the requirements for the safety of power equipment are also becoming more stringent. However, shutting down for maintenance would seriously affect people's normal lives and factory operations, causing significant economic losses. Nowadays, plastic greenhouses and garbage dumps are often found near power transmission equipment and corridors. In windy weather, easily floating and flammable foreign objects such as discarded plastics often become entangled in power transmission cables. If not dealt with in time, this can easily lead to short circuits between lines, and in severe cases, fires in power equipment.

[0003] Patent CN105098633A discloses a foreign object removal device for power equipment maintenance, comprising: an insulating rod providing support; a motor fixed to the upper end of the insulating rod; a base connected to the output shaft of the motor, the motor driving the base to rotate; and a winding member connected to the base, which rotates when driven by the base. This invention can reach near debris on power equipment to cut or shred it. Therefore, this invention can quickly, conveniently, simply, and reliably remove high-level debris from power equipment, ensuring the safe operation of the power system.

[0004] Patent CN108110663A discloses a multi-purpose foreign object remover for power equipment maintenance, comprising a connecting sleeve, an adjustable extension rod structure, a replaceable screwdriver structure, a primary fastening bolt, a secondary fastening bolt, a protective sleeve, a foreign object striking hammer structure, and a foreign object forced removal hook and puller structure. The design of the primary single-ended screw, primary fastening nut, long nut, secondary single-ended screw, and secondary fastening nut allows for easy adjustment of the remover's length according to foreign object removal needs, enabling long-distance foreign object removal. The inclusion of a movable plate, movable bolt, threaded tube, tension spring, and fixed plate allows for foreign object removal in relatively narrow spaces.

[0005] In reality, when floating objects such as plastic bags and kite strings are entangled in cables, the entanglement is often quite firm, and the cables are generally not taut, making removal even more difficult. Since the foreign object removal device in the aforementioned patent does not have the function of straightening the cable and cutting the entangled objects on the cable, it is quite difficult to remove floating objects entangled in swaying cables, which greatly affects the work efficiency of the staff.

[0031] 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.

[0032] Example 1:

[0033] This invention provides a foreign object removal device for the maintenance of power equipment, such as... Figure 1-7As shown, the device includes an operating lever 1. An anti-slip sleeve, made of rubber, is fixedly connected to the outer surface of the operating lever 1. This sleeve not only increases the friction between the hand and the operating lever 1 but also provides insulation. An electric push rod 2 is fixedly connected to the upper end of the operating lever 1. The electric push rod 2 is existing technology and can extend and retract to adjust the length between the operating lever 1 and the electric push rod 2. A horizontal support rod 4 is located above the electric push rod 2. Two symmetrical connecting rods 3 are fixedly connected to the upper end of the electric push rod 2. The end of each connecting rod 3 furthest from the electric push rod 2 is fixedly connected to the outer surface of the horizontal support rod 4. The connecting rods 3 connect and fix the electric push rod 2 to the horizontal support rod 4, and the connecting rods 3 can also be made of insulating material.

[0034] A movable rod 7 is provided on the outside of the transverse support rod 4. An electric push rod 8 is fixedly connected between the transverse support rod 4 and the movable rod 7. The electric push rod 8 is existing technology and is controlled by an external controller. When the electric push rod 8 extends or retracts, it can drive the movable rod 7 to move closer to or away from the transverse support rod 4. Two symmetrical clamping mechanisms 6 are provided at both ends of the transverse support rod 4. The clamping mechanism 6 includes a limiting rod 61 and two symmetrical clamping plates 62. Anti-slip pads are fixed on the side of the two clamping plates 62 that are close to each other, which can increase the friction between the clamping plates 62 and the cable.

[0035] Two symmetrical transmission mechanisms 9 are provided between the transverse support rod 4 and the moving rod 7. The transmission mechanisms 9 can push the cutting and dismantling mechanism 10 to move when the moving rod 7 moves. Each transmission mechanism 9 is equipped with a cutting and dismantling mechanism 10 on its exterior. The transmission mechanism 9 includes a slider 93. A rotating rod 94 is rotatably connected to the outer surface of the slider 93. Transmission rod 95 and transmission rod 98 are respectively hinged to the two ends of the rotating rod 94. The movement of the moving rod 7 can pull one end of the rotating rod 94 to rotate through the transmission rod 95.

[0036] Since the slider 93 is rotatably connected to the middle of the rotating rod 94, and the hinge of the transmission rod 98 and the rotating rod 94 is provided with a damping structure and the damping effect is good, the transmission rod 98 will not rotate arbitrarily. Therefore, the cutting and dismantling mechanism 10 can be moved by the transmission rod 98. The cutting and dismantling mechanism 10 includes a fixed shell 100, and a telescopic rod 102 is fixedly connected to the inner wall of the fixed shell 100. A spring is installed inside the telescopic rod 102, which enables the telescopic rod 102 to have the function of extension and retraction.

[0037] Example 2:

[0038] Each clamping plate 62 is rotatably connected to the outer surface of the limiting rod 61. Each clamping plate 62 has a hinge rod 63 hinged to its outer surface. When the hinge rod 63 moves, it can drive the two clamping plates 62 to open and close. The limiting rod 61 has a connecting block 64 on its outside. The end of each hinge rod 63 away from the clamping plate 62 is hinged to the connecting block 64. When the connecting block 64 moves, it can drive the two clamping plates 62 to rotate through the hinge rod 63. A fixing rod 65 is fixedly connected to the outer surface of the connecting block 64. A sliding rod 66 is fixedly connected to the end of the fixing rod 65 away from the connecting block 64. The sliding rod 66 can connect the fixing rod 65 to the moving rod 7. When the moving rod 7 moves, it can push the fixing rod 65 to move.

[0039] The end of the slide rod 66 away from the fixed rod 65 is slidably connected to the inside of the moving rod 7. It can adjust the distance between the clamping mechanism 6 and the moving rod 7 according to the extension and retraction of the electric push rod 2 5. Both ends of the transverse support rod 4 are fixedly connected to the electric push rod 2 5. The electric push rod 2 5 is existing technology. The extension and retraction of the electric push rod 2 5 is controlled by the controller, which can control the distance between the two clamping mechanisms 6. The ends of the two electric push rods 2 5 away from the transverse support rod 4 are fixedly connected to the outer surfaces of the two limit rods 61 respectively. When the electric push rod 2 5 extends and retracts, it can drive the limit rod 61 to move.

[0040] The transmission mechanism 9 also includes a limiting groove 91 formed on the outer surface of the transverse support rod 4. A guide groove 92 is formed on the inner top wall of the limiting groove 91. Both the limiting groove 91 and the guide groove 92 pass through the transverse support rod 4. The slider 93 is slidably connected inside the limiting groove 91. The limiting groove 91 can limit and guide the slider 93. A moving block 99 is fixedly connected to the upper surface of the slider 93. The moving block 99 is slidably connected inside the guide groove 92. The guide groove 92 can guide the moving block 99.

[0041] The outer surface of the movable rod 7 has a groove 97, and a slide bar 96 is slidably connected inside the groove 97. The end of the transmission rod 95 away from the rotating rod 94 is fixedly connected to the outer surface of the slide bar 96. The slide bar 96 slides inside the groove 97, which allows the transmission rod 95 to be connected to the movable rod 7 while also allowing the transmission rod 95 to move.

[0042] Example 3:

[0043] The fixed housing 100 is fixedly connected to the end of the transmission rod 2 98 away from the rotating rod 94. The end of the telescopic rod 102 away from the fixed housing 100 is fixedly connected to the mounting strip 103. The cutting blade 104 is installed inside the mounting strip 103. Screws arranged at equal intervals are installed on the outer surface of the mounting strip 103. The screws pass through the mounting strip 103 and the cutting blade 104, and the cutting blade 104 is fixed inside the mounting strip 103 by the screws. When the cutting blade 104 is worn or damaged, it is convenient to replace the cutting blade 104.

[0044] The outer surface of the fixed housing 100 is fixedly connected with support rods 101 arranged at equal intervals. Each support rod 101 is equipped with a roller at the end away from the fixed housing 100. When the cutting blade 104 cuts the floating entanglement outside the cable, the roller will contact the cable, making it convenient for the cutting blade 104 to move outside the cable.

[0045] The outer surface of the transverse support rod 4 is fixedly connected to a fixing plate 13 and a fixing plate 2 14. A bidirectional screw 11 is rotatably connected between the fixing plate 13 and the fixing plate 2 14. The fixing plate 13 and the fixing plate 2 14 facilitate the installation of the bidirectional screw 11. The bidirectional screw 11 passes through the moving block 99 and is threadedly connected to the moving block 99. When the bidirectional screw 11 rotates, it can drive the moving block 99 to move. The outer surface of the fixing plate 2 14 is fixedly connected to a power motor 12. The power motor 12 is existing technology. It serves as the power source for the rotation of the bidirectional screw 11 and can be replaced by other power sources. The output shaft of the power motor 12 passes through the fixing plate 2 14 and is rotatably connected to the fixing plate 2 14. The output shaft of the power motor 12 is fixedly connected to one end of the bidirectional screw 11. When the power motor 12 is turned on by an external controller, it can drive the bidirectional screw 11 to rotate, thereby enabling the moving block 99 to move.

[0046] Working principle:

[0047] When removing floating debris such as plastic bags or kite strings from a cable, firstly, raise the horizontal support rod 4 to the position of the cable. Then, position the cable between the clamping plates 62. At this time, control the extension of the electric push rod 3 8 via the controller. When the electric push rod 3 8 extends, it increases the distance between the horizontal support rod 4 and the moving rod 7. At this time, the moving rod 7 moves the fixed rod 65 and the connecting block 64 via the slide rod 66, causing the two clamping plates 62 to rotate relative to each other, thus clamping the cable between the two clamping plates 62. Then, control the extension of the electric push rod 2 5, which can move the two clamping mechanisms 6 away from each other, keeping the cable taut. At this time, the floating debris is located between the two clamping mechanisms 6. While the electric push rod 3 8 extends, the moving rod 7 pulls the transmission rod 1 95. Due to the lever principle, the transmission rod 1 95 pushes the transmission rod 2 98 to move through the rotational connection between the slider 93 and the rotating rod 94, which can move the fixed shell 100 toward the cable. As the fixed housing 100 moves closer to the cable, the cutting blade 104 first contacts the cable. As the fixed housing 100 continues to move towards the cable, the telescopic rod 102 retracts, and the spring inside the telescopic rod 102 provides support, ensuring that the cutting blade 104 remains in contact with the outer surface of the cable. At this time, the support rod 101 contacts the outer surface of the cable, facilitating the movement of the cutting blade 104 on the outer surface of the cable. Then, the power motor 12 is activated, driving the bidirectional screw 11 to rotate. The rotation of the bidirectional screw 11 drives the moving block 99 to reciprocate, which in turn drives the cutting and removal mechanism 10 to move. This mechanism can cut and remove floating debris wrapped around the outer surface of the cable. This device can first straighten the swaying cable, keeping it taut, and then cut off the floating debris wrapped around it. It is convenient and quick to use, greatly increasing the work efficiency of the staff.
