Description

Technical Field

[0001] The present invention relates to the technical field of protective device equipment, and particularly to a construction protection device for transmission and transformation lines and its usage method. Background Technique

[0002] The construction protection device for transmission and transformation lines is a safety protection device designed to ensure the safety of construction workers and the normal operation of equipment during the construction of transmission and transformation lines. This device usually includes multiple protection function modules, such as electrical insulation, electric shock prevention, falling object prevention, warning prompts, automatic monitoring and other systems, which can effectively cope with various potential hazards in the construction environment. It uses high-strength protection materials and advanced technologies to ensure the maximum protection of the safety of construction workers and equipment in high-voltage and high-current environments.

[0003] During the process of line construction, workers need to work on utility poles. During the operation, construction tools may accidentally fall. In areas with concentrated urban population, there is a possibility of hitting the masses. Conventional protective nets are elastic, which can have a certain buffering force and can reduce the impact force of falling objects. However, the impact force will also generate elastic force and bounce out of the protective net again, resulting in a second fall. The second fall may pose a risk of falling to the ground and injuring the masses. Summary of the Invention

[0012] Furthermore, a method for constructing a protection device for a power transmission and transformation line is provided, and the method steps are as follows: S1: Prevent dropped objects from falling again; S2: Clearing snow; S3: Improve cleaning; S4: Stabilize the device.

[0013] The present invention has the following beneficial effects: (1) The present invention provides a power transmission and transformation line construction protection device. When a construction tool accidentally falls during the construction process, it will directly fall onto the fixed rope in the elastic protection net. At this time, the fixed rope is not tightened. When the tool falls onto the fixed rope, the fixed rope will be buffered during the loosening process. The fixed rope will reduce the gravitational potential energy elastic force of the falling tool. At this time, the elastic protection net will drive the fixed rope to descend, the fixed rope will drive the internal thread block to descend, and the internal thread block will drive the sliding rectangular plate to descend. The sliding rectangular plate generates a buffer force under the action of the buffer spring to buffer the impact force of the falling object. Then the falling object will fall into the elastic protection net from the gaps between the fixed ropes to prevent the falling object from falling directly to the ground and hitting passers-by. After the falling object enters the elastic protection net, it will also generate an upward elastic force. Since the gravitational potential energy of the falling object is weakened, the upward rebound force of the falling object in the elastic protection net will also be reduced. At this time, the falling object will be blocked by the fixed rope when it bounces up, so that the falling object will not leave the elastic protection net, ensuring that the falling object will not fall again. (2) The present invention provides a power transmission and transformation line construction protection device. When snow falls into the elastic protection net and accumulates, the drive motor is started, the drive motor drives the double-threaded rod to rotate, the double-threaded rod drives the pulley to rotate, the pulley drives the synchronous belt to rotate, the synchronous belt drives the transmission wheel rod to rotate, the transmission wheel rod will contact the L-shaped transmission plate during the rotation process, the L-shaped transmission plate will push the L-shaped transmission plate down during the rotation of the transmission wheel rod, the L-shaped transmission plate drives the elastic protection net to stretch downward and deform, after the transmission wheel rod leaves the L-shaped transmission plate, the L-shaped transmission plate will rebound and rise under the elastic action of the elastic protection net, at this time the elastic protection net will vibrate violently, and the snow in the elastic protection net will be shaken out of the elastic protection net, thereby preventing the elastic protection net from being crushed due to the accumulation of snow, thereby protecting the normal use of the elastic protection net; (3) The invention provides a power transmission and transformation line construction protection device. During the rotation of the double-threaded rod, the two internal thread blocks are driven to move away from each other, and the internal thread blocks are driven to move away from each other. The fixed ropes will vertically stretch the elastic protection net. At this time, the plurality of fixed ropes in the elastic protection net will also be tightened at the same time. The gaps between the tightened fixed ropes will become larger, and the fixed ropes will be tighter. When the snow in the elastic protection net is shaken out, the snow will be directly cut when it hits the fixed ropes, making it easier to shake out the snow, thereby improving the efficiency of clearing the snow. (4) The present invention provides a power transmission and transformation line construction protection device. When installing the device, the first support plate is fixed at a specified position, and then the second support plate is pulled. When the second support plate moves in a direction away from the first support plate, the second support plate will drive the limit plate to move at the same time, and the L-shaped fixing rod will continue to descend under the action of the limit groove. When the second support plate moves to the specified position, the L-shaped fixing rod will move to the bottom of the limit groove. At this time, the L-shaped fixing rod will contact the ground under the limiting action of the limit groove. At this time, the second support plate will be more stable under the friction force of the L-shaped fixing rod, thereby ensuring the overall stability of the device and improving the installation and disassembly efficiency of the device.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown, the present invention is a protection device for transmission and transformation line construction, including a first support plate 1 and a second support plate 2. There are two fixed cables 3 arranged between the first support plate 1 and the second support plate 2, and an elastic protective net 4 is fixedly installed on the two fixed cables 3. It also includes: A jitter mechanism 5, the jitter mechanism 5 includes two C-shaped frames 501 respectively arranged between the first support plate 1 and the second support plate 2. Two double threaded rods 502 are respectively rotated on the two C-shaped frames 501. The two double threaded rods 502 respectively penetrate the two C-shaped frames 501. The front surfaces of the two C-shaped frames 501 are respectively fixedly installed with driving motors 503. The output shafts of the two driving motors 503 are respectively fixedly connected to the two double threaded rods 502. A rotating shaft 504 is arranged between the first support plate 1 and the second support plate 2. Pulley 505 is fixedly sleeved on the rotating shaft 504 and the two double threaded rods 502 respectively. A synchronous belt 506 is fixedly sleeved on several pulleys 505. A transmission wheel rod 507 is fixedly sleeved on the rotating shaft 504. The bottom of the elastic protective net 4 is fixedly installed with an L-shaped transmission plate 508.

[0020] Such as Figure 5 And Figure 6As shown, a plurality of ventilation holes 509 are respectively opened on the first support plate 1 and the second support plate 2, and a plurality of limiting hollow plates 510 are respectively hingedly installed on the first support plate 1 and the second support plate 2. The plurality of limiting hollow plates 510 are grouped in pairs, and sliding limiting plates 511 are respectively slidably installed in the plurality of groups of limiting hollow plates 510, and two hinge components 512 are hingedly installed on the plurality of groups of limiting hollow plates 510.

[0021] When the second support plate 2 leaves the first support plate 1 , the sliding limit plate 511 will slide in the limit hollow plate 510 , supporting the first support plate 1 and the second support plate 2 , thereby ensuring the stability of the first support plate 1 and the second support plate 2 .

[0022] like Figure 6 and Figure 7 As shown, a fixing mechanism 6 is provided on the two hinge assemblies 512, and the fixing mechanism 6 includes a rotating rod 601 fixedly installed on the side where the two hinge assemblies 512 are close to each other, an L-shaped transmission plate 508 passes through the rotating rod 601 and is slidably connected to the rotating rod 601, a sliding round rod 602 is rotatably sleeved on the rotating rod 601, the sliding round rod 602 passes through the second support plate 2 and is slidably connected to the second support plate 2, a mounting block 1 603 is fixedly installed on the right end of the sliding round rod 602, a mounting block 2 604 is provided below the mounting block 1 603, a telescopic rod 605 is fixedly installed on the bottom of the mounting block 1 603, the bottom end of the telescopic rod 605 is fixedly connected to the mounting block 2 604, a telescopic spring 606 is sleeved on the telescopic rod 605, the top end of the telescopic spring 606 is fixedly connected to the mounting block 1 603, and the bottom end of the telescopic spring 606 is fixedly connected to the mounting block 2 604.

[0023] During the movement of the L-shaped fixed rod 609, the mounting block 2 604 will drive the telescopic rod 605 to move, and the telescopic rod 605 will gradually extend and reach the specified position of the limit groove 608. When the second support plate 2 approaches the first support plate 1, the telescopic rod 605 will contract under the elastic force of the mounting block 2 604, so that the L-shaped fixed rod 609 leaves the ground, thereby improving the flexibility of the device.

[0024] like Figure 7 As shown, two limit plates 607 are fixedly installed on the right side of the second support plate 2, and limit slots 608 are respectively provided on the two limit plates 607. L-shaped fixing rods 609 are respectively fixedly installed on the sides of the two mounting blocks 604 away from each other, and the two L-shaped fixing rods 609 respectively penetrate the two limit slots 608 and are respectively slidably connected to the two limit slots 608.

[0025] The second support plate 2 will drive the limit plate 607 to move simultaneously. The L-shaped fixing rod 609 will continuously descend under the action of the limit groove 608. When the second support plate 2 moves to the specified position, at this time, the L-shaped fixing rod 609 will move to the bottom of the limit groove 608. At this time, the L-shaped fixing rod 609 will contact the ground under the limiting action of the limit groove 608. At this time, the second support plate 2 will be more stable under the frictional force of the L-shaped fixing rod 609, ensuring the overall stability of the device and improving the installation and disassembly efficiency of the device.

[0026] As Figure 1 and Figure 3 shown, tensioning mechanisms 7 are respectively arranged on two double threaded rods 502. The tensioning mechanism 7 includes two internal thread blocks 701 threadedly sleeved on the double threaded rods 502. The two internal thread blocks 701 are respectively fixedly connected to two fixing cables 3. A limit sliding rod 702 is fixedly installed on the C-shaped frame 501. The limit sliding rod 702 penetrates through the two internal thread blocks 701 and is slidably connected to the two internal thread blocks 701. A plurality of fixing ropes 703 are fixedly installed on the elastic protection net 4.

[0027] During the rotation of the double threaded rod 502, it will drive the two internal thread blocks 701 to move away from each other. The internal thread block 701 will drive the two fixing cables 3 to move away from each other. The fixing cables 3 will vertically stretch the elastic protection net 4. At this time, a plurality of fixing ropes 703 inside the elastic protection net 4 will also be tightened simultaneously. The gaps between the tightened plurality of fixing ropes 703 will become larger, and the fixing ropes 703 will be tighter. When shaking out the snow in the elastic protection net 4, the snow will directly be cut open when it touches the fixing ropes 703, making the snow easier to be shaken out and improving the efficiency of snow cleaning.

[0028] As Figure 3 shown, an installation groove 704 is formed on the first support plate 1. Two circular rods 705 are fixedly installed in the installation groove 704. A sliding rectangular plate 706 is slidably sleeved on the two circular rods 705. The front surface of the sliding rectangular plate 706 is fixedly connected to the C-shaped frame 501. Buffer springs 707 are respectively sleeved on the two circular rods 705. The top ends of the two buffer springs 707 are fixedly connected to the sliding rectangular plate 706. The bottom ends of the two buffer springs 707 are fixedly connected to the installation groove 704.

[0029] The internal thread block 701 drives the sliding rectangular plate 706 to descend. Under the action of the buffer spring 707, the sliding rectangular plate 706 generates a buffer force to buffer the impact force of the falling object. Then the falling object falls into the elastic protection net 4 through the gaps between several fixing ropes 703, preventing the falling object from directly hitting the ground and hitting passers-by. After the falling object enters the elastic protection net 4, an upward elastic force will also be generated. Since the gravitational potential energy of the falling object is weakened, the upward rebound force of the falling object on the elastic protection net 4 will also be reduced at this time. At this time, the falling object that bounces up will be blocked by the fixing ropes 703, so that the falling object will not leave the elastic protection net 4, ensuring that the falling object will not fall again.

[0030] As Figure 3 shown, two U-shaped frames 501 are respectively provided with an adaptation mechanism 8. The adaptation mechanism 8 includes two adaptation springs 801 fixedly installed on the mutually close sides of the U-shaped frames 501. The mutually close ends of the two adaptation springs 801 are respectively fixedly installed with adaptation ring blocks 802. The double threaded rod 502 and the limit slide rod 702 both penetrate through the adaptation springs 801 and the adaptation ring blocks 802.

[0031] During the process of the internal thread blocks 701 moving away from each other, they will contact the adaptation ring blocks 802. The internal thread blocks 701 drive the adaptation ring blocks 802 to move away from each other. After the internal thread blocks 701 leave the threads on the double threaded rod 502, the adaptation ring blocks 802 will顶住 the internal thread blocks 701 under the elastic force of the adaptation springs 801, keeping the internal thread blocks 701 in a semi-disengaged state from the threads. At this time, the stability of the internal thread blocks 701 will not affect the normal rotation of the double threaded rod 502.

[0032] As Figure 1 - Figure 8 shown, a method for a power transmission and transformation line construction protection device is as follows: S1: Prevent the falling object from falling again; S2: Clear the snow; S3: Improve the cleaning; S4: Stabilize the device.

[0033] If a construction tool accidentally falls during the construction process, it will directly fall onto the fixed rope 703 in the elastic protection net 4. At this time, the fixed rope 703 is not tightened. When the tool falls onto the fixed rope 703, the fixed rope 703 will be buffered during the loosening process. The fixed rope 703 will reduce the gravitational potential energy elastic force of the falling tool. At this time, the elastic protection net 4 will drive the fixed rope 3 to descend, the fixed rope 3 will drive the internal thread block 701 to descend, and the internal thread block 701 will drive the sliding rectangular plate 706 to descend. The plate 706 generates a buffer force under the action of the buffer spring 707 to buffer the impact force of the falling object, and then the falling object will fall into the elastic protection net 4 from the gaps between the plurality of fixed ropes 703 to prevent the falling object from falling directly to the ground and hitting passers-by. After the falling object enters the elastic protection net 4, an upward elastic force will also be generated. Since the gravitational potential energy of the falling object is weakened, the upward rebound force of the falling object in the elastic protection net 4 will also be reduced. At this time, the falling object will be blocked by the fixed rope 703 when it bounces up, making the falling object The falling objects will not leave the elastic protective net 4, ensuring that the fallen objects will not fall again; when the snow falls into the elastic protective net 4 and accumulates, the driving motor 503 is started, the driving motor 503 drives the double-threaded rod 502 to rotate, the double-threaded rod 502 drives the pulley 505 to rotate, the pulley 505 drives the synchronous belt 506 to rotate, and the synchronous belt 506 drives the transmission wheel rod 507 to rotate, and the transmission wheel rod 507 will contact the L-shaped transmission plate 508 during the rotation process, and the L-shaped transmission plate 508 will push the L-shaped transmission plate 508 to descend during the rotation of the transmission wheel rod 507, and the L-shaped transmission plate 508 drives the elastic protective net 4 to stretch and deform downward, and after the transmission wheel rod 507 leaves the L-shaped transmission plate 508, the L-shaped transmission plate 508 will rebound and rise under the elastic action of the elastic protective net 4, and at this time, the elastic protective net 4 will vibrate violently, shaking the accumulated snow in the elastic protective net 4 out of the elastic protective net 4, thereby preventing the elastic protective net 4 from being crushed due to the accumulation of snow, thereby protecting the normal use of the elastic protective net 4; When the double-threaded rod 502 rotates, the two internal thread blocks 701 will move away from each other, and the internal thread block 701 will drive the two fixing ropes 3 to move away from each other. The fixing ropes 3 will stretch the elastic protective net 4 vertically. At this time, the multiple fixing ropes 703 in the elastic protective net 4 will also be tightened at the same time. The gaps between the tightened multiple fixing ropes 703 will become larger, and the fixing ropes 703 will be tighter. When shaking out the snow in the elastic protective net 4, the snow will be directly cut when it hits the fixing ropes 703, making it easier to shake out the snow, thereby improving the efficiency of clearing the snow. When installing the device, fix the first support plate 1 at a specified position The second support plate 2 is positioned, and then the second support plate 2 is pulled. When the second support plate 2 moves in the direction away from the first support plate 1, the second support plate 2 will drive the limiting plate 607 to move at the same time, and the L-shaped fixing rod 609 will continue to descend under the action of the limiting groove 608. When the second support plate 2 moves to the specified position, the L-shaped fixing rod 609 will move to the bottom of the limiting groove 608. At this time, the L-shaped fixing rod 609 will contact the ground under the limiting action of the limiting groove 608. At this time, the second support plate 2 will be more stable under the friction force of the L-shaped fixing rod 609, thereby ensuring the overall stability of the device and improving the installation and disassembly efficiency of the device.
