Description

Technical Field

[0001] This invention relates to the field of cable de-icing equipment technology, specifically to a de-icing device suitable for outdoor cables. Background Technology

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of conductors. It plays an important role in the modern information transmission field. During the use of cables, they will face different operating environments. For example, in cold northern regions or during winter snowfall, ice and icicles can easily form on the outdoor surface of the cable. This icing will place a large weight load on the cable, which may lead to serious accidents such as cable breakage and tower collapse.

[0003] Currently, cable de-icing operations include manual de-icing, where workers climb to high altitudes to remove ice. This method is inefficient and dangerous. Thermal de-icing involves inputting a large current into the power grid to raise the temperature of the wires and prevent icing. However, this method consumes a lot of energy and can cause economic losses. Mechanical de-icing is also used, such as using drones to drive collision rods to collide with the cables for de-icing. However, this method can easily damage the cables during the collision process. Summary of the Invention

[0004] The purpose of this invention is to provide a de-icing device suitable for outdoor cables to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a de-icing device suitable for outdoor cables, comprising a housing mounted on the cable, the housing consisting of an upper housing and a lower housing connected by bolts, a rolling mechanism mounted on the housing for moving the device on the cable, and an ice-clearing mechanism mounted on the housing, the ice-clearing mechanism consisting of guide rods for clearing ice and snow through collision and impact, for removing ice and snow from the cable during the movement of the device.

[0007] Furthermore, the rolling mechanism consists of two mounting frames, a lower roller, an upper roller, a moving motor, and a thumb telescopic rod. The two mounting frames are respectively mounted on the upper and lower outer shells, with the mounting frame on the lower outer shell in a sliding connection state. The lower and upper rollers are respectively set on the lower and upper outer shells and are rotatably connected to their respective mounting frames. Both the lower and upper rollers are connected to the outer wall of the cable. The moving motor is set on the upper outer shell and connected to its corresponding mounting frame. The moving motor and the upper roller are connected via gear meshing. The thumb telescopic rod is mounted on the lower outer shell, and its telescopic shaft is connected to the mounting frame on the lower outer shell.

[0008] Furthermore, the ice-clearing mechanism consists of a movable frame and guide rods. The movable frame is divided into an upper frame and a lower frame, which are respectively set on the upper outer shell and the lower outer shell. Both the upper frame and the lower frame are arc-shaped and are connected by plug-in joints. The guide rods are installed on the movable frame, and there are multiple guide rods arranged in a ring.

[0009] Furthermore, the lower and upper rollers are provided with annular grooves. The annular grooves are used to adapt to the shape of the cable and can form a limit on the lower and upper rollers, making the connection between the lower and upper rollers and the cable more secure. The annular grooves are provided with long grooves filled with wear-resistant silicone to enhance the connection between the lower and upper rollers and the cable.

[0010] Furthermore, an avoidance groove is provided on the upper roller, which is located in the middle of the upper roller. A half gear is provided on the inner wall of the avoidance groove. A limit plate is installed on the mounting bracket on the upper shell. A movable plate is slidably installed on the limit plate. The movable plate is meshed with the half gear. One side of the movable plate is connected to the upper frame. A return spring is provided on the limit plate. The other end of the return spring is connected to the movable plate. The return spring allows the movable plate to return to its initial position after movement without external force.

[0011] Furthermore, the guide rod is hollow and has multiple air inlets. The guide rod is connected to the moving frame. An air cylinder is installed on the upper outer shell, and a piston is installed on the air cylinder. A transmission frame is installed on the upper roller, and part of the transmission frame extends into the air cylinder and is connected to the piston. The transmission frame causes the upper roller to drive the piston up and down during rotation, generating an impact airflow. An air pipe is installed on the air cylinder and is connected to the moving frame. The airflow in the air cylinder is transmitted to the guide rod through the air pipe and discharged through the air inlets.

[0012] Furthermore, stop plates are installed on both the upper and lower outer shells, and cleaning sponges are installed on both the upper and lower frames. The cleaning sponges are connected to the stop plates. Under normal conditions, the cleaning sponges are in a contracted state. During the movement of the moving frame, the cleaning sponges are stretched, causing them to extend. The expansion and contraction of the cleaning sponges can squeeze out the water absorbed by the sponges.

[0013] Furthermore, a transmission block is installed on the guide rod, and the transmission block contacts the adjacent guide rod. A limit frame is installed on the upper shell, and a transmission rod is installed on one of the transmission blocks. One end of the transmission rod passes through the limit frame and is movably connected to the limit frame. A pulling component is rotatably installed on the limit frame, and a collision ball is set on the limit frame. The collision ball contacts the transmission rod. A cable is set on the limit frame, with one end of the cable connected to the collision ball and the other end connected to the pulling component. A rotating component is installed on one end of the upper roller, and the rotating component is adapted to the pulling component. The rotating component contacts the rotating component as the upper roller rotates, causing the rotating component to rotate. Pulling the cable pulls the collision ball to move. As the rotating component continues to move, it disengages from the pulling component, and the collision ball falls and collides with the transmission rod, generating vibration. This vibration then drives the guide rod to vibrate through the transmission block, improving the snow and ice clearing effect.

[0014] Furthermore, a counterweight is provided on the bottom inner wall of the lower outer shell. The counterweight is made of lead and is used to increase the weight of the bottom of the lower outer shell. After the lower outer shell is connected to the upper outer shell, the lower outer shell pulls on the upper outer shell, making the connection between the upper roller on the upper outer shell and the cable more stable.

[0015] The present invention has the following beneficial effects:

[0016] (1) This invention uses an upper and lower roller clamping method to drive the equipment to move under the action of a moving motor. By setting a guide rod, the ice attached to the cable surface is knocked off during the movement of the equipment, thereby completing the de-icing operation. The equipment structure is relatively simple, reducing the cost of de-icing. At the same time, since the upper and lower shells are connected by bolts, they can be quickly disassembled, thereby improving the ease of disassembly and assembly of the equipment. Under the action of the thumb telescopic rod, the distance between the lower and upper rollers can be adjusted to ensure the stability of the equipment movement, thereby ensuring the stability of the equipment de-icing.

[0017] (2) The present invention uses the rotation of the upper roller to drive the piston to make piston movement in the air guide cylinder, thereby generating airflow. The airflow enters the guide rod after passing through the air guide pipe and the moving frame, and then acts on the surface of the cable through the air punch. Thus, after the guide rod is inserted into the ice, the air jet can improve the ice removal rate and improve the cable de-icing effect. At the same time, the impact of the airflow can also wash the water on the surface of the cable, ensuring the cleanliness of the cable surface and reducing the probability of subsequent icing of the cable.

[0018] (3) By setting a half gear on the upper roller, the guide rod can be extended and retracted during the movement of the equipment under the action of the moving plate, the limiting plate and the return spring. This can reduce the impact of the collision force on the equipment when the guide rod comes into contact with the ice, thus achieving the effect of buffering the equipment. At the same time, the extension and retraction of the guide rod can drive the air hole on it to move, so that the airflow can be applied to the surface of the cable more comprehensively, improving the cleaning effect on the cable surface.

[0019] (4) The present invention uses a cleaning sponge to clean the water flow on the cable surface, thereby further improving the cleaning effect on the cable surface. By extending and retracting the above-mentioned moving frame, the cleaning sponge can be extended and squeezed, thereby removing the water flow absorbed by the cleaning sponge during the squeezing process, ensuring the water absorption effect of the cleaning sponge, and achieving a clean effect on the cable surface.

[0020] (5) By setting up a transmission block and a transmission rod, the present invention can drive the rotating part to rotate during the rotation of the upper roller. The rotating part drives the pulling part to rotate, which in turn pulls the collision ball to rise. After the rotating part rotates to a certain angle, it disengages from the pulling part. Under the action of gravity, the collision ball contacts the transmission rod, thereby generating vibration. The vibration force acts on the guide rod, causing the guide rod to vibrate. The vibration of the guide rod can improve the ice removal effect. At the same time, the sound shock wave generated by the collision of the collision ball and the transmission rod has a probability of causing the ice attached to the cable to fall off. At the same time, the sound propagation can also remind the operator that the equipment is working, providing safe conditions for the normal de-icing of the cable.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0034] Please see Figures 1-8 As shown, this invention is a de-icing device suitable for outdoor cables, including a housing mounted on the cable 1. The housing consists of an upper housing 3 and a lower housing 2, which are connected by bolts. The upper housing 3 is provided with a positioning plug, and the lower housing 2 is provided with a positioning socket. The positioning plug and the positioning socket are adapted to limit the movement of the upper housing 3 and the lower housing 2 during installation, ensuring the accuracy of the installation. The housing is provided with a rolling mechanism, which is used to move the device on the cable 1. The housing is also provided with an ice-clearing mechanism, which consists of a guide rod 11. The ice-clearing mechanism clears ice and snow through collision and impact, and is used to remove ice and snow from the cable 1 during the movement of the device.

A circular gear 3 is sleeved on the upper roller 6. Circular gear 1 is meshed with both circular gear 2 and circular gear 3. A thumb telescopic rod 27 is mounted on the lower shell 2. The telescopic shaft of the thumb telescopic rod 27 is connected to the mounting bracket 4 located on the lower shell 2. The thumb telescopic rod 27 is powered by electricity and is used to adjust the distance between the lower roller 5 and the upper roller 6. The lower roller 5 and the upper roller 6 are provided with annular grooves. The annular grooves are used to adapt to the shape of the cable 1 and can form a limit on the lower roller 5 and the upper roller 6, making the connection between the lower roller 5 and the upper roller 6 and the cable 1 more secure. A long groove is opened in the annular groove and filled with wear-resistant silicone to enhance the connection and tightness between the lower roller 5 and the upper roller 6 and the cable 1.

[0036] The ice-clearing mechanism consists of a movable frame 10 and guide rods 11. The movable frame 10 is divided into an upper frame and a lower frame, which are respectively set on the upper outer shell 3 and the lower outer shell 2. Both the upper frame and the lower frame are arc-shaped and are connected by plug-in joint. Both sides of the upper frame are provided with inward limiting grooves, and both sides of the lower frame are provided with outward protrusions. The protrusions and limiting grooves are adapted to each other, so that the movable frame 10 is in a sealed state after the assembly is completed. The guide rods 11 are installed on the movable frame 10. There are multiple guide rods 11, which are arranged in a ring.

[0037] An avoidance groove is provided on the upper roller 6, which is located in the middle of the upper roller 6. A half gear 9 is provided on the inner wall of the avoidance groove. A limit plate 7 is installed on the mounting bracket 4 on the upper outer shell 3. A movable plate 8 is slidably installed on the limit plate 7. A T-shaped groove is provided on the limit plate 7.

A gear plate is provided at the bottom of the movable plate 8 for cooperating with the half gear 9. One side of the movable plate 8 is connected to the upper frame. A return spring is provided on the limit plate 7. The other end of the return spring is connected to the movable plate 8. The return spring allows the movable plate 8 to return to its initial position after movement without external force.

[0038] The guide rod 11 is hollow and has multiple air holes angled downwards at 45 to 60 degrees to blow airflow onto the surface of the cable 1. The guide rod 11 is made of stainless steel cylinder and is connected to the moving frame 10. An air guide cylinder 14 is mounted on the upper outer shell 3, and a piston 15 is mounted on the air guide cylinder 14. A transmission frame 13 is mounted on the upper wire roller 6, with a portion extending into the air guide cylinder 14 and connecting to the piston 15. The transmission frame 13 specifically consists of a turntable, a connecting plate one, and a connecting plate two. The turntable is mounted on the upper wire roller 6, and the connecting plate one is rotatably mounted on the turntable in an eccentric configuration. Plate 2 is rotatably mounted on connecting plate 1. The other side of connecting plate 2 extends into air guide cylinder 14 and is slidably connected to air guide cylinder 14. Limiting strips for moving connecting plate 2 are provided on the upper outer shell 3 to ensure that connecting plate 2 is in a vertical up-and-down movement state. The upper roller 6 drives piston 15 to move up and down during rotation through transmission frame 13, generating impact airflow. Air guide pipe 16 is installed on air guide cylinder 14 and is connected to moving frame 10. Airflow in air guide cylinder 14 is transmitted to guide rod 11 through air guide pipe 16 and discharged through air purging hole. Part of air guide pipe 16 is made of retractable hose material to facilitate the movement of moving frame 10.

[0039] Both the upper outer shell 3 and the lower outer shell 2 are equipped with stop plates 18, and both the upper frame and the lower frame are equipped with cleaning sponges 17. The cleaning sponges 17 are connected to the stop plates 18. Under normal conditions, the cleaning sponges 17 are in a contracted state. During the movement of the moving frame 10, the cleaning sponges 17 will be pulled, causing the cleaning sponges 17 to extend. The expansion and contraction of the cleaning sponges 17 can squeeze out the water absorbed by the sponges.

[0040] A transmission block 19 is installed on the guide rod 11. The transmission block 19 contacts the adjacent guide rod 11. Specifically, a corresponding transmission block 19 is installed on a single guide rod 11. After the moving frame 10 is assembled, the transmission blocks 19 on multiple guide rods 11 form a ring and are sleeved on multiple guide rods 11, forming a vibration force transmission device. A limit frame 21 is installed on the upper outer shell 3. A transmission rod 20 is installed on one of the transmission blocks 19. One end of the transmission rod 20 passes through the limit frame 21 and is movably connected to the limit frame 21. A pulling member 24 is rotatably installed on the limit frame 21. A collision ball 22 is provided on the limit frame 21. The collision ball 22 contacts the transmission rod 20. A pull cable 23 is provided on the limit frame 21. One end of the pull cable 23 is connected to the collision ball 22, and the other end of the pull cable 23 is connected to the pulling member 24. One end of the upper roller 6 is installed with The rotating component 25 is adapted to the pulling component 24. The rotating component 25 rotates with the upper roller 6 and comes into contact with the upper roller 6, causing the rotating component 25 to rotate. This pulls the cable 23, which in turn pulls the collision ball 22 to move. As the rotating component 25 continues to move, it disengages from the pulling component 24. The collision ball 22 falls and collides with the transmission rod 20, generating vibration. This vibration then drives the guide rod 11 to vibrate through the transmission block 19, improving the snow and ice removal effect. Specifically, the rotating component 25 consists of a collar and a round bar. The collar is fitted onto the upper roller 6, and the round bar is mounted on the collar. The pulling component 24 consists of a rotating rod and two round bars. The rotating rod is rotatably mounted on the limiting frame 21, and the two round bars are symmetrically mounted on the rotating rod. One of the round bars is connected to the cable 23, and the other round bar has an arc-shaped groove that is adapted to the round bar and is used to contact the round bar.

[0041] A counterweight 26 is provided on the bottom inner wall of the lower outer shell 2. The counterweight 26 is made of lead and is used to increase the weight of the bottom of the lower outer shell 2. After the lower outer shell 2 is connected to the upper outer shell 3, the lower outer shell 2 pulls on the upper outer shell 3, making the connection between the upper roller 6 on the upper outer shell 3 and the cable 1 more stable.

[0042] In use, the upper outer shell 3 and the lower outer shell 2 are bolted to the surface of the cable 1. The distance between the lower roller 5 and the upper roller 6 is adjusted by the thumb telescopic rod 27, so that the lower roller 5 and the upper roller 6 fit better against the surface of the cable 1, ensuring the stability of the equipment movement. During this process, the moving frame 10 is also assembled.

[0043] The starting motor 12 drives the upper roller 6 to rotate. Under the action of the upper roller 6 and the lower roller 5, the entire equipment moves, driving the guide rod 11 to move. The guide rod 11 collides with the ice on the surface of the cable 1, thereby achieving the effect of de-icing the surface of the cable 1. At the same time, during the rotation of the upper roller 6, the guide rod 11 is driven to reciprocate under the action of the half gear 9, the moving plate 8, and the limiting plate 7, thereby reducing the hard collision between the guide rod 11 and the ice. During the rotation of the upper roller 6, the piston 15 is indirectly driven to make piston movement in the air guide cylinder 14, generating airflow that acts on the surface of the cable 1 through the air vent on the guide rod 11, thereby improving the de-icing effect and cleaning the surface of the cable 1, reducing the probability of the cable 1 re-icing. At the same time, during the rotation of the upper roller 6, the rotating part 25 is driven to rotate, thereby driving the pull The moving part 24 rotates, and then pulls the collision ball 22 upward through the cable 23. After the rotating part 25 rotates at a certain angle, it separates from the pulling part 24. Under the action of gravity, the collision ball 22 collides with the transmission rod 20 and generates vibration. The vibration force is transmitted to the guide rod 11 through the transmission rod 20 and the transmission block 19, thereby driving the guide rod 11 to vibrate and improving the de-icing effect of the guide rod 11. At the same time, the cleaning sponge 17 can clean the surface of the cable 1 after de-icing, reducing the probability of the cable 1 freezing again. During the extension and retraction of the guide rod 11, the moving frame 10 will also move accordingly. During this process, the cleaning sponge 17 will switch between an extended state and a squeezed state. By squeezing the cleaning sponge 17, the water removal effect of the cleaning sponge 17 is achieved, thereby ensuring the water removal effect of the cleaning sponge 17 on the surface of the cable 1.
