Description

Technical Field

[0001] This invention relates to the field of obstacle removal device technology, and in particular to an overhead line obstacle removal device and method. Background Technology

[0002] During use, overhead power lines are prone to malfunctions due to contact with external debris such as tree branches, plastic bags, and light bulbs.

[0003] Regarding the existing overhead line clearing devices: Currently, when moving by vehicle, the vehicle needs to be manually locked after it stops, which is cumbersome and cannot automatically brake when the vehicle stops. Existing devices cannot achieve the coordination between the adjustment structure and the carrying structure, so as to enable the carrying structure to adjust the obstacle clearing device at the same time, and to expand the adjustment range. Summary of the Invention

[0004] In view of this, the present invention provides an overhead line clearing device and method, which has a pushing part. By setting the pushing part, the device can automatically brake when the vehicle is stopped and automatically release the brake when the vehicle is pushed. It also features a laser cleaning section, which allows for angle adjustment and easy portability.

[0005] The purpose and effectiveness of the overhead line clearing device and method of the present invention are achieved by the following specific technical means: This invention provides an overhead power line clearing device and method, specifically comprising: a vehicle body, a pushing part, a laser cleaning part, an auxiliary part, and a supporting part; two roller shafts are rotatably connected to the vehicle body, each roller shaft is equipped with two rollers, both rollers are in contact with the ground; a placement seat is welded to the middle of the top surface of the vehicle body; two cleaning blocks are welded to the left and right end surfaces of the vehicle body, all four cleaning blocks are triangular prism structures, all four cleaning blocks are in contact with the top surface of the outer wall of the rollers, and the four cleaning blocks together form the cleaning structure for the mud on the rollers; the pushing part consists of a mounting plate, a first sliding rod, a spring, a connecting arm, a brake block, and a pusher arm, and the mounting plate is welded to the vehicle body; the laser cleaning part consists of a battery, a mounting seat, a locking nut, and a laser clearer, and the battery is inserted into the placement seat; the auxiliary part consists of a motor, an impeller, a connecting plate, and a heating wire, and the motor is mounted on the top surface of the battery; the supporting part consists of a sliding seat, a second sliding rod, a support seat, an adjusting screw, and a rubber sleeve, and the sliding seat is welded to the top surface of the vehicle body.

[0006] Furthermore, two first sliding rods are welded to the rear end face of the mounting plate, and a trolley arm is slidably connected to the two first sliding rods. Both first sliding rods are stepped shaft-shaped structures, and a spring for the trolley arm to return to its rearward position is sleeved on each of the two first sliding rods. Two connecting arms are welded to the trolley arm, and a brake block is welded to each connecting arm. Both brake blocks are in elastic contact with the top surface of the outer wall of a rear roller shaft. Grooves are arranged in a ring array on the rear roller shaft.

[0007] Furthermore, when the trolley arm is pushed forward 5cm, the brake block disengages from a rear roller shaft, thus releasing the brake on the rear roller shaft.

[0008] Furthermore, the placement seat is a cylindrical tubular structure, and the outer wall of the placement seat has through holes arranged in a ring array, which form the drainage structure of the placement seat; the inner wall of the placement seat is provided with rollers arranged in a ring array, the rollers are cylindrical rod-shaped structures, the top surface of the outer wall of the ring array of rollers contacts the bottom surface of the battery, and the inner wall of the placement seat is polished.

[0009] Furthermore, a mounting base is rotatably connected to the battery via a rotating shaft, and a laser obstacle clearer is rotatably connected to the mounting base via a rotating shaft. A locking nut is threaded onto the rotating shaft, and when the locking nut is tightened, the mounting base and the laser obstacle clearer are in a fixed state.

[0010] Furthermore, the mounting base has a concave structure and serves as a carrying structure for the battery and the laser obstacle clearer.

[0011] Furthermore, an impeller is mounted on the rotating shaft of the motor, and the impeller is located 20cm below the laser obstacle clearer; Two connecting plates are symmetrically installed on the top of the battery. Heating wires are installed in a linear array between the two connecting plates. The heating wires are electrically connected to the battery and are located 18cm below the laser obstacle clearer.

[0012] Furthermore, two second sliding rods are symmetrically slidably connected to the sliding seat. The upper end of each of the two second sliding rods is welded to the bottom of the support seat. An adjusting screw is threaded onto the sliding seat, and the upper end of the adjusting screw is rotatably connected to the support seat. The support seat is engaged with the laser obstacle clearer. A wiping block is attached to the support seat, and the wiping block contacts the lens of the laser obstacle clearer.

[0013] Furthermore, a rubber sleeve is attached to the handle of the adjusting screw, and the rubber sleeve makes elastic contact with the sliding seat.

[0014] A method for clearing obstructions from overhead power lines includes the following steps: 01. Push the vehicle to the obstacle removal position; 02. When the vehicle moves to the obstacle clearing position, the push arm moves backward under the action of the spring, and at this time the brake block realizes the braking of one of the rear roller shafts; 03. Rotate the adjusting screw to move the support seat downwards; 04. Loosen the locking nut. This allows you to adjust the angle of the mounting base and raise the angle of the laser obstacle clearer. After adjusting, tighten the locking nut. 05. When adjusting the level, simply hold the mounting base and rotate it; 06. Rotate the adjusting screw to move the support downwards, thus blocking the laser obstacle clearer lens.

[0015] Beneficial effects This application enables multi-directional adjustment of the laser obstacle clearer through the design of the laser cleaning section, as follows: A mounting base is rotatably connected to the battery via a rotating shaft, and a laser obstacle clearer is rotatably connected to the mounting base via the same rotating shaft. A locking nut is threaded onto the rotating shaft. When the locking nut is tightened, the mounting base and the laser obstacle clearer are fixed in place. During use, when the locking nut is loosened, the mounting base can be adjusted at an angle, and then the laser obstacle clearer can also be adjusted at an angle on the mounting base. This expands the angle adjustment range of the laser obstacle clearer.

[0016] The placement base allows for the placement and rotation of the laser cleaning component while preventing rainwater from soaking the battery. Specifically: First, the inner wall of the placement base features a circular array of rollers, each a cylindrical rod. The top surface of the outer wall of these rollers contacts the bottom surface of the battery. The inner wall of the placement base is polished, facilitating battery rotation during use and consequently, the rotation of the laser obstacle clearer. Second, because the placement base is a cylindrical tubular structure, its outer wall has a circular array of through holes, forming a drainage structure that prevents rainwater accumulation and potential damage to the battery.

[0017] By designing the push mechanism, the vehicle can automatically brake when stopped and automatically disengage when pushed. Specifically: Two first sliding rods are welded to the rear end of the mounting plate, and a push arm is slidably connected to each rod. Both first sliding rods are stepped shaft-shaped structures, and each rod is fitted with a spring for the push arm to return to its original position. Two connecting arms are welded to the push arm, and each arm has a brake block welded to it. Both brake blocks are in elastic contact with the top surface of the outer wall of a rear roller shaft. The rear roller shaft has grooves arranged in a circular array, allowing the brake blocks to engage the rear roller shaft. When the push arm is pushed forward 5cm, the brake blocks disengage from the rear roller shaft, releasing the brake. With this improvement, after the vehicle stops and the operator releases the push arm, the brake blocks elastically contact the rear roller shaft under the action of the springs, achieving automatic braking.

[0018] The mounting base allows for both angle adjustment of the laser cleaning component and convenient portability. Specifically, the concave shape of the mounting base, which serves as a carrying mechanism for both the battery and the laser obstacle clearer, allows for easy transport in areas where movement is difficult, improving flexibility during use.

[0019] The support structure protects the laser cleaning lens after use, as follows: After use, rotating the adjusting screw causes the support to engage with the laser obstacle remover, protecting the lens. Two second sliding rods are symmetrically connected to the sliding base, with their upper ends welded to the bottom of the support. The adjusting screw is threaded onto the sliding base, with its upper end rotatably connected to the support, engaging the laser obstacle remover. A wiping block is attached to the support, contacting the lens of the laser obstacle remover. During use, rotating the adjusting screw raises the support, allowing for cleaning and protection of the laser obstacle remover.

[0020] By setting up cleaning blocks, the dirt on the rollers can be automatically cleaned when the rollers rotate. Specifically, two cleaning blocks are welded to the left and right ends of the vehicle body. All four cleaning blocks are triangular prism structures and are in contact with the top surface of the outer wall of the rollers. The four cleaning blocks together form the dirt cleaning structure on the rollers. When the rollers rotate, the dirt on the rollers can be automatically cleaned through the cleaning blocks.

[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0033] Example: Please refer to Figures 1 to 8 : This invention proposes an overhead line clearing device and method, comprising: a vehicle body 1, a pushing part 2, a laser cleaning part 4, an auxiliary part 6, and a supporting part 7; Two roller shafts 101 are rotatably connected to the vehicle body 1. Each roller shaft 101 is equipped with two rollers 102, and both rollers 102 are in contact with the ground. A placement seat 3 is welded to the middle of the top surface of the vehicle body 1. The pushing part 2 consists of a mounting plate 201, a first sliding rod 202, a spring 203, a connecting arm 204, a brake block 205, and a pusher arm 206. The mounting plate 201 is welded to the vehicle body 1. The laser cleaning part 4 consists of a battery 401, a mounting base 402, a locking nut 403, and a laser obstacle clearer 404. The battery 401 is inserted into the placement base 3. The auxiliary part 6 consists of a motor 601, an impeller 602, a connecting plate 603, and a heating wire 604. The motor 601 is mounted on the top surface of the battery 401. The support part 7 consists of a sliding seat 701, a second sliding rod 702, a support seat 703, an adjusting screw 704, and a rubber sleeve 705. The sliding seat 701 is welded to the top surface of the vehicle body 1.

[0034] Two cleaning blocks 103 are welded to the left and right ends of the vehicle body 1. All four cleaning blocks 103 are triangular prisms. All four cleaning blocks 103 are in contact with the top surface of the outer wall of the roller 102. The four cleaning blocks 103 together form the cleaning structure for the mud on the roller 102. When the roller 102 rotates, the mud on the roller 102 can be automatically cleaned through the cleaning blocks 103.

[0035] Among them, two first sliding rods 202 are welded to the rear end face of the mounting plate 201, and a trolley arm 206 is slidably connected to the two first sliding rods 202. Both first sliding rods 202 are stepped shaft structures, and a spring 203 for the trolley arm 206 to return to its rearward position is sleeved on each of the two first sliding rods 202. Two connecting arms 204 are welded on the trolley arm 206. Each connecting arm 204 is welded with a brake block 205. Both brake blocks 205 are in elastic contact with the top surface of the outer wall of a rear roller shaft 101. The rear roller shaft 101 has grooves arranged in a ring array. At this time, the brake blocks 205 can be used to brake the rear roller shaft 101.

[0036] When the pusher arm 206 is pushed forward 5cm, the brake block 205 disengages from the rear roller shaft 101, thus releasing the brake on the rear roller shaft 101. With the above improvement, after the vehicle body 1 stops and the staff releases the pusher arm 206, the brake block 205 elastically contacts the rear roller shaft 101 under the action of the spring 203 to achieve automatic braking.

[0037] The placement seat 3 is a cylindrical tubular structure. The outer wall of the placement seat 3 has through holes 301 arranged in a ring array. The through holes 301 arranged in a ring array form the drainage structure of the placement seat 3. During use, it can prevent rainwater from accumulating in the placement seat 3, thereby preventing rainwater from soaking and damaging the battery 401.

[0038] The inner wall of the placement base 3 is provided with rollers 302 arranged in a ring array. The rollers 302 are cylindrical rod-shaped structures. The top surface of the outer wall of the rollers 302 arranged in a ring array contacts the bottom surface of the battery 401. The inner wall of the placement base 3 is polished so that the battery 401 can rotate easily during use, which also facilitates the subsequent rotation of the laser obstacle clearer 404.

[0039] The battery 401 is rotatably connected to a mounting base 402 via a rotating shaft. A laser obstacle clearer 404 is rotatably connected to the mounting base 402 via a rotating shaft. A locking nut 403 is threaded onto the rotating shaft. When the locking nut 403 is tightened, the mounting base 402 and the laser obstacle clearer 404 are fixed. During use, when the locking nut 403 is loosened, the mounting base 402 can be adjusted at an angle, and then the laser obstacle clearer 404 can also be adjusted at an angle on the mounting base 402. This expands the angle adjustment range of the laser obstacle clearer 404.

[0040] The mounting base 402 has a concave structure and serves as a carrying structure for the battery 401 and the laser obstacle clearer 404. In locations where it is inconvenient to walk on the vehicle body 1, the mounting base 402 can be held by hand for carrying, which improves the flexibility of use.

[0041] Among them, an impeller 602 is installed on the rotating shaft of the motor 601, and the impeller 602 is located 20cm below the laser obstacle clearer 404; Two connecting plates 603 are symmetrically mounted on the top of the battery 401. Heating wires 604 are mounted in a linear array between the two connecting plates 603. The heating wires 604 are electrically connected to the battery 401 and are located 18cm below the laser obstacle clearer 404. During use, in summer, the rotation of the motor 601 can drive the impeller 602 to rotate, thereby cooling the laser obstacle clearer 404. In winter, the heating wires 604 can be used to increase the temperature of the laser obstacle clearer 404.

[0042] Two second sliding rods 702 are symmetrically slidably connected to the sliding seat 701. The upper ends of the two second sliding rods 702 are welded to the bottom of the support seat 703. The adjusting screw 704 is threadedly connected to the sliding seat 701. The upper end of the adjusting screw 704 is rotatably connected to the support seat 703. The support seat 703 is snapped into the laser obstacle clearer 404. A wiping block is attached to the support seat 703. The wiping block contacts the lens of the laser obstacle clearer 404. During use, when the adjusting screw 704 is rotated, the support seat 703 can be raised. At this time, the laser obstacle clearer 404 can be wiped and protected through the support seat 703.

[0043] The adjusting screw 704 has a rubber sleeve 705 attached to its handle. The rubber sleeve 705 is in elastic contact with the sliding seat 701. The sliding seat 701 can reduce the chance of the adjusting screw 704 becoming loose by pressing against the rubber sleeve 705.

[0044] A method for clearing obstructions from overhead power lines includes the following steps: 01. Push the vehicle body 1 to the obstacle removal position; 02. When the vehicle body 1 moves to the obstacle clearing position, the push arm 206 moves backward under the action of the spring 203. At this time, the brake block 205 is used to brake the rear roller shaft 101. 03. Rotate the adjusting screw 704 to move the support 703 downward; 04. Loosen the locking nut 403. At this time, the angle of the mounting base 402 can be adjusted, and the angle of the laser obstacle clearer 404 can be raised. After adjustment, tighten the locking nut 403. 05. When adjusting the level, simply hold the mounting base 402 and rotate it; 06. Rotate the adjusting screw 704 to move the support 703 downward, thereby blocking the lens of the laser obstacle clearer 404.

[0045] The specific usage and function of this embodiment are as follows: When in use, first push the vehicle body 1 to the obstacle clearing position. At this time, since there are two cleaning blocks 103 welded on the left and right ends of the vehicle body 1, all four cleaning blocks 103 are triangular prism structures. All four cleaning blocks 103 are in contact with the top surface of the outer wall of the roller 102. The four cleaning blocks 103 together form the structure for cleaning the mud on the roller 102. When the roller 102 rotates, the mud on the roller 102 can be automatically cleaned through the cleaning blocks 103. Meanwhile, two first sliding rods 202 are welded to the rear end face of the mounting plate 201. A trolley arm 206 is slidably connected to the two first sliding rods 202. Both first sliding rods 202 are stepped shaft structures, and a spring 203 for the trolley arm 206 to return to its rearward position is sleeved on each of the two first sliding rods 202. Two connecting arms 204 are welded to the trolley arm 206, and a brake block 205 is welded to each connecting arm 204. Both brake blocks 205 spring against the top surface of the outer wall of a rear roller shaft 101. The rear roller shaft 101 has grooves arranged in a circular array. At this time, the brake block 205 can brake the rear roller shaft 101. When the pusher arm 206 is pushed forward 5cm, the brake block 205 disengages from the rear roller shaft 101, and the brake on the rear roller shaft 101 can be released. With the above improvement, after the vehicle body 1 stops and the staff releases the pusher arm 206, the brake block 205 elastically contacts the rear roller shaft 101 under the action of the spring 203 to achieve automatic braking. When encountering difficult road sections where the vehicle body 1 cannot pass, the user can hold the mounting base 402 to carry it. When adjusting the angle, the locking nut 403 can be loosened. This allows for adjustment of the angle of the mounting base 402 and increases the angle of the laser obstacle clearer 404. After adjustment, the locking nut 403 should be tightened. When rotation is required, the mounting base 402 can be rotated by holding it. Rollers 302 are arranged in a circular array on the inner wall of the placement base 3. The rollers 302 are cylindrical rod-shaped structures. The top surface of the outer wall of the circular array of rollers 302 contacts the bottom surface of the battery 401. The inner wall of the placement base 3 is polished, which facilitates the rotation of the battery 401 during use, and also facilitates the directional rotation of the laser obstacle clearer 404. When used in summer, because the impeller 602 is installed on the rotating shaft of the motor 601, and the impeller 602 is located 20cm below the laser obstacle clearer 404, the laser obstacle clearer 404 can be cooled down by rotating the impeller 602 through the rotation of the motor 601 in summer. In winter, the laser obstacle clearer 404 can be heated by the heating wire 604. After use, rotate the adjusting screw 704. Driven by the adjusting screw 704, the support 703 engages with the laser obstacle clearer 404, thus protecting the lens of the laser obstacle clearer 404. At this time, two second sliding rods 702 are symmetrically slidably connected on the sliding seat 701. The upper ends of the two second sliding rods 702 are welded to the bottom of the support 703. The adjusting screw 704 is threadedly connected to the sliding seat 701, and the upper end of the adjusting screw 704 is rotatably connected to the support 703. The support 703 engages with the laser obstacle clearer 404. A wiping block is attached to the support 703 and contacts the lens of the laser obstacle clearer 404. During use, when the adjusting screw 704 is rotated, the support 703 can be raised. At this time, the laser obstacle clearer 404 can be wiped and protected through the support 703. When used in rainy weather, because the placement seat 3 is a cylindrical tubular structure, the outer wall of the placement seat 3 has through holes 301 arranged in a ring array. The through holes 301 arranged in a ring array form the drainage structure of the placement seat 3, which can prevent rainwater from accumulating in the placement seat 3 during use, thereby preventing rainwater from soaking and damaging the battery 401.
