Description

Technical Field

[0001] This utility model relates to the field of laser obstacle removal technology, specifically to a laser obstacle removal instrument with protective functions. Background Technology

[0002] Overhead power lines are prone to catching loose debris due to abnormal weather conditions, posing a serious threat to their safe operation. If this debris remains entangled on the lines for an extended period, it can compromise the safety of the power grid. Therefore, power maintenance departments must promptly remove any debris found on overhead power lines to ensure safe operation. Laser debris removal equipment is typically used to clear debris from overhead power lines. The principle behind laser debris removal is to use remote focusing technology to precisely control a high-energy laser beam to remotely irradiate the gravity-supported parts, the parts entangled in the conductor, or the parts adhered to the debris. The irradiated parts absorb the laser energy, causing a rapid increase in local temperature, resulting in melting or vaporization, and the debris falls off, thus achieving remote removal. Laser debris removal equipment can emit controllable lasers from the ground to cut and remove high-altitude debris from a distance, enabling live, remote, and non-contact operation.

[0003] Commercially available laser obstacle removal devices typically require the use of a tripod. The tripod is installed on the lower side of the laser obstacle removal device to stably set it up on the ground, allowing workers to control the laser's direction. However, when workers use laser obstacle removal devices in the field to clear hanging objects from overhead power lines, there are situations where the device needs to be set up on soft, damp mud or dry sand. Tripod legs are usually telescopic rods with small outer diameters and small lower end faces. Therefore, when the tripod is set up on mud or sand, the legs can easily sink into the ground due to excessive pressure, making it impossible to set up the laser obstacle removal device stably. This causes inconvenience in using the laser obstacle removal device and increases the possibility of it tipping over and being damaged. Utility Model Content

[0004] The purpose of this invention is to provide a laser obstacle removal instrument with protective functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a laser obstacle removal instrument with protective functions, comprising a main body of the laser obstacle removal instrument, a tripod set below the main body of the laser obstacle removal instrument, the tripod including a vertical rod fixedly set on the lower side wall of the main body of the laser obstacle removal instrument, a convex ring coaxially fixed at the middle position of the vertical rod, three telescopic legs extending obliquely downwards are hinged in a ring array on the circumferential side wall of the convex ring, a base is set at the middle position of the lower end of the three telescopic legs, and a lifting mechanism for adjusting the distance between the base and the vertical rod is set on the vertical rod, the base and the lifting mechanism are movably connected, and the base is used to stabilize the position of the vertical rod when it is working.

[0006] As a further improvement to this technical solution, the bottom of the upright is coaxially provided with an installation groove, and the lifting mechanism includes a lead screw coaxially rotatably disposed inside the installation groove. A first nut is threaded onto the lead screw, and three extension rods are fixedly arranged in a ring array on the lower side wall of the first nut. The lower end of the extension rods extends to the bottom of the upright.

[0007] As a further improvement to this technical solution, the lifting mechanism also includes a three-pronged plate coaxially fixed to the lower side wall of the upright. The three-pronged plate is composed of three straight plates arranged in a ring array and welded together at one end. Three slots are formed between the side wall of the three-pronged plate and the inner wall of the mounting groove, and the three extension rods pass through the corresponding slots respectively.

[0008] As a further improvement to this technical solution, the lifting mechanism also includes a driven gear coaxially fixed to the lead screw near the top, and a driving gear rotatably disposed on the outer side wall of the upright, one side of the driving gear penetrating the side wall of the upright and meshing with the driven gear.

[0009] As a further improvement to this technical solution, a sliding sleeve is slidably fitted on the upright below the convex ring. A connecting rod is hinged to the circumferential side wall of the sliding sleeve at the position corresponding to each telescopic outrigger. The other end of the connecting rod is hinged to the non-piston rod of the corresponding telescopic outrigger.

[0010] As a further improvement to this technical solution, a threaded rod is vertically fixed at the middle position of the upper side wall of the chassis, and the lifting mechanism also includes a second nut that is threadedly connected to the threaded rod. The second nut is fixedly set at the middle position of the lower end of the three extension rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This protective laser obstacle removal device, when the lower end of the telescopic outriggers contacts sand or mud, after initially setting up the main body of the laser obstacle removal device on the ground, the chassis is fixed to the lower side of the second nut by threaded rods. Then, the worker rotates the drive gear and adjusts the distance between the upper side wall of the chassis and the lower end of the upright through the lifting mechanism until the lower side wall of the chassis touches the ground and supports the laser obstacle removal device. This prevents the lower end of the telescopic outriggers from sinking into the ground, ensuring the stability of the main body of the laser obstacle removal device when used on mud or sand. At the same time, the chassis lowers the center of gravity of the laser obstacle removal device, reducing the possibility of the laser obstacle removal device tipping over if the worker accidentally touches it.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1 and Figure 2 As shown, one of the objectives of this embodiment is to provide a laser obstacle removal instrument with protective functions, including a laser obstacle removal instrument body 1. The laser obstacle removal instrument body 1 is electrically connected to an external storage battery during use, which powers the instrument. This facilitates workers using the laser obstacle removal instrument body 1 in the field to clear hanging objects on overhead power lines. A tripod 2 is installed below the laser obstacle removal instrument body 1 to stably support the instrument body 1 on the ground. The tripod 2 includes a vertical rod 21 fixedly installed on the lower side wall of the instrument body 1. A convex ring 211 is coaxially fixed at the middle position of the vertical rod 21. Three telescopic legs 22 extending obliquely downwards are hinged in a circular array on the circumferential side wall of the convex ring 211. Each telescopic leg 22 consists of three sleeves connected sequentially. A latch fixed to one of the sleeves is provided at the connection point of adjacent sleeves to lock the two adjacent sleeves together. The sleeve hinged to the convex ring 211 is the non-piston rod of the telescopic leg 22. At the same time, a sliding sleeve 23 is slidably sleeved on the upright 21 below the convex ring 211. The circumferential sidewall of the sliding sleeve 23 is hinged to a connecting rod 24 at a position corresponding to each telescopic leg 22. The other end of the connecting rod 24 is hinged to the non-piston rod of the corresponding telescopic leg 22. When the laser obstacle clearing instrument is used, the worker rotates the lower end of one of the telescopic legs 22 away from the axis of the upright 21. This causes the telescopic leg 22 to drive the sliding sleeve 23 to move downward along the axis of the upright 21 through the corresponding connecting rod 24. The moving sliding sleeve 23 then drives the corresponding telescopic leg 22 to rotate synchronously through the other two connecting rods 24 until the distance between the connection point of the connecting rod 24 and the sliding sleeve 23 and the connection point of the telescopic leg 22 is the farthest. At this point, the connecting rod 24 prevents the lower end of the telescopic leg 22 from continuing to rotate away from the axis of the upright 21, thus completing the deployment of the tripod 2.

[0027] By touching the ground with the lower ends of the three telescopic outriggers 22, and utilizing the principle that three points determine a plane, the tripod 2 and the main body 1 of the laser obstacle removal instrument can be stably placed on the ground. At this time, the connecting rod 24 is in a horizontal state. The length of the two sleeves on the telescopic outriggers 22, except for the piston rod, extending beyond the adjacent upper sleeve is adjustable. After adjusting the length of the sleeves extending beyond the adjacent upper sleeve, the positions of the two sleeves can be locked using the corresponding latches. The overall length of the telescopic outriggers 22 can be adjusted. By adjusting the length of the three telescopic outriggers 22 one after another, the height of the main body 1 of the laser obstacle removal instrument on the ground can be adjusted, making it convenient for workers of different heights to use the main body 1 of the laser obstacle removal instrument.

[0028] When the lower end of the telescopic outrigger 22 contacts soft, wet mud or dry sand, the lower end of the outrigger 22 is prone to sinking into the mud or sand, causing the laser obstacle removal instrument body 1 to be unable to be stably erected on the ground. If the lower end of the telescopic outrigger 22 suddenly sinks into the ground while workers are using the laser obstacle removal instrument body 1 to clear hanging objects from overhead power lines, the laser obstacle removal instrument body 1 is likely to tip over and be damaged due to collision with hard objects. To solve this problem, refer to... Figure 3 , Figure 6 and Figure 7 A base 25 is installed at the middle of the lower end of the three telescopic outriggers 22. The outer diameter of the base 25 is ten times or more the outer diameter of the upright 21, ensuring that the base 25 can provide good support for the laser obstacle removal instrument after it touches the ground. The upright 21 is equipped with a lifting mechanism 26 for adjusting the distance between the base 25 and the upright 21. The base 25 and the lifting mechanism 26 are movably connected. The base 25 is used to stabilize the position of the upright 21 when it is working. After the worker sets up the unfolded tripod 2 on the mud or sand, the worker installs the base 25 on the lifting mechanism 26. The worker adjusts the distance between the upper side wall of the base 25 and the lower end of the upright 21 through the lifting mechanism 26 until the lower side wall of the base 25 touches the ground completely. This allows the tripod 2 and the main body 1 of the laser obstacle removal instrument to be placed stably on the ground, ensuring the stability of the main body 1 of the laser obstacle removal instrument during use. At the same time, the base 25 lowers the center of gravity of the laser obstacle removal instrument, reducing the possibility of the laser obstacle removal instrument tipping over if the worker accidentally touches it.

[0029] Reference Figure 3 and Figure 4 An mounting groove 212 is coaxially provided at the bottom of the upright 21. The structure of the lifting mechanism 26 is described in detail below, referring to... Figure 5The lifting mechanism 26 includes a lead screw 261 coaxially rotatably disposed inside the mounting groove 212. A first nut 262 is threaded onto the lead screw 261. Three extension rods 263 are fixedly arranged in a ring array on the lower side wall of the first nut 262. The lower ends of the extension rods 263 extend to the bottom of the upright 21. A threaded rod 251 is vertically fixed at the middle position of the upper side wall of the chassis 25. The lifting mechanism 26 also includes a second nut 267 threadedly connected to the threaded rod 251. The second nut 267 is fixedly disposed at the middle position of the lower ends of the three extension rods 263. The chassis 25 is threadedly fixed to the lower side of the second nut 267 by the threaded rod 251. Through the threaded connection of the threaded rod 251 and the second nut 267, the chassis 25 is installed on the lower side of the lifting mechanism 26, so that the chassis 25 can be disassembled and installed from the lifting mechanism 26.

[0030] The lifting mechanism 26 also includes a three-pronged plate 266 coaxially fixed to the lower side wall of the upright 21. The three-pronged plate 266 is composed of three straight plates arranged in a ring array and welded together at one end. Three slots are formed between the side wall of the three-pronged plate 266 and the inner wall of the mounting groove 212. Three extension rods 263 pass through the corresponding slots respectively, that is, the extension rods 263 slide in contact with the inner wall of the corresponding slots. The slots restrict the corresponding extension rods 263 to move only along the axial direction of the upright 21.

[0031] The lifting mechanism 26 also includes a driven gear 264 coaxially fixed to the lead screw 261 near its top. A driving gear 265 is rotatably mounted on the outer wall of the upright 21. One side of the driving gear 265 passes through the side wall of the upright 21 and meshes with the driven gear 264. A knob is coaxially fixed to the lower end of the driving gear 265. When the worker holds the knob and rotates the driving gear 265, the meshing transmission between the driving gear 265 and the driven gear 264 causes the driven gear 264 to drive the lead screw. When rod 261 rotates, the slot prevents extension rod 263 and first nut 262 from rotating with lead screw 261. Then, through the threaded connection between lead screw 261 and first nut 262, first nut 262 drives extension rod 263 to move downward along the axis of lead screw 261. The moving extension rod 263 drives the base 25 to move synchronously through second nut 267, thereby adjusting the distance between base 25 and upright rod 21, so that base 25 can support the main body 1 of laser obstacle removal instrument.

[0032] When using this device on mud or sand, the worker unfolds the tripod 2 so that the lower end of the telescopic outrigger 22 touches the ground, initially setting up the main body 1 of the laser obstacle removal instrument on the ground. Then, the worker screws the base 25 onto the lower side of the second nut 267 using the threaded rod 251. The worker then rotates the drive gear 265 and adjusts the distance between the upper side wall of the base 25 and the lower end of the upright 21 through the lifting mechanism 26 until the lower side wall of the base 25 is completely in contact with the ground. This prevents the lower end of the telescopic outrigger 22 from sinking into the ground, ensuring that the worker can stably set up the tripod 2 and the main body 1 of the laser obstacle removal instrument on the mud or sand. At the same time, the base 25 lowers the center of gravity of the laser obstacle removal instrument, reducing the possibility of the laser obstacle removal instrument tipping over if the worker accidentally touches it, and preventing the main body 1 of the laser obstacle removal instrument from colliding with the ground and being damaged.
