Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage transmission lines, and in particular relates to a blasting deicing and detonating device and system for overhead high-voltage transmission lines. Background Art

[0002] Ultra-high voltage transmission lines are prone to ice formation under the unique winter weather conditions. This increases the weight load on the wires and towers, leading to ice buildup. Ice buildup can cause tripping at the very least, or even tower collapse and line breakage at the worst. The resulting power outages and even grid disconnection can be extremely serious, making repairs difficult and time-consuming. Therefore, workers must promptly remove ice from the surfaces of high-voltage transmission lines.

[0003] An existing public document with publication number CN110676788B discloses a clamping hardware for detonating cords used for blasting and deicing overhead transmission lines, which belongs to the field of high-voltage transmission lines. The technical problem to be solved is to provide a clamping hardware with a simple structure and easy use, which can achieve deicing by clamping and hanging detonating cords.

[0004] It can be seen from the comparative documents that when breaking ice on the surface of high-voltage wires, the existing technology is to use blasting de-icing clamps to break ice on the surface of high-voltage wires, but these are often disposable products. When large-scale de-icing is required, a large number of products need to be used, which consumes more manpower and material resources, is not conducive to work efficiency, and easily causes waste of resources. Utility Model Content

[0005] The present invention is intended to solve the technical problems raised in the background technology. The existing technology is to break ice on the surface of high-voltage lines through blasting deicing clamps, but these are often disposable products. When large-area deicing is required, a large number of products need to be used, which consumes more manpower and material resources, is not conducive to work efficiency, and is likely to cause resource waste. For this reason, a blasting deicing detonating device and system for overhead high-voltage transmission lines are proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A blasting deicing detonator for overhead high-voltage transmission lines comprises two clamping plates, each of which has a vertical plate disposed on its upper side, the two ends of which are connected by an elastic mechanism, the two ends of the lower side of each clamping plate being fixedly connected to a connecting shaft, the lower end of each connecting shaft being fixedly mounted with a counterweight, the upper ends of the two clamping plates being inclined to form an inclined portion and being close to each other, the sides of the inclined portions of the two clamping plates being located away from each other being recessed outward to form a storage cavity, the storage cavity being filled with safety explosives for breaking ice;

[0008] The elastic mechanism includes a connecting plate, and the inner sides of both ends of the two connecting plates are connected to a clamping plate through an elastic member, one end of the clamping plate is clamped with the splint, and an insert block is provided on the side of the two clamping plates facing each other, and an installation shaft for use with the elastic mechanism is inserted between the two adjacent connecting plates, and the insert block is clamped with the end of the installation shaft.

[0009] Preferably, the elastic member is a spring, and both ends of the spring are fixedly connected to the clamping plate and the connecting plate respectively.

[0010] Preferably, a card slot is provided on the side of the splint, and a bent plug plate is provided at the lower end of the card plate, and the plug plate is inserted into the card slot, an upper baffle is provided at one end of the plug plate, and the upper baffle is fitted with the inner wall of the vertical plate, and a lower baffle is provided at the other end of the plug plate, and the end of the lower baffle is fitted with the surface of the splint.

[0017] The present invention also provides a blasting deicing and detonating system for overhead high-voltage transmission lines, comprising a drone and the blasting deicing and detonating device for overhead high-voltage transmission lines provided by the present invention.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The device can be directly installed on the wire that needs to break ice. During the ice breaking process, the impact of the safety explosives exerts an outward force on the splints on both sides. Under the impact and the resulting angular deviation, the splints lose the restriction of the elastic mechanism and will separate from each other, eventually falling from the high-voltage line.

[0020] 2. After the icebreaking operation is completed, the splint and the elastic mechanism of the device will separate from each other and fall off. After assembling the splint and the elastic mechanism, they can be used again. It is only necessary to re-glue new icebreaking safety explosives in the storage chamber. The installation method is very simple and can be recycled many times. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] Reference Figures 1-4A blasting and deicing detonating device for overhead high-voltage transmission lines includes two splints 1. A vertical plate 10 is provided on the upper side of the two splints 1. The two ends of the vertical plates 10 are connected by an elastic mechanism. The two ends of the lower side of the splint 1 are fixedly connected to a connecting shaft 3. The lower end of each connecting shaft 3 is fixedly installed with a counterweight 4. A storage cavity 2 is provided at the middle position of the two splints 1. The upper ends of the two splints 1 are inclined to form an oblique portion and are close to each other. The side of the oblique portions of the two splints 1 that are away from each other is concave outward to form a storage cavity 2. Safety explosives for breaking ice are pasted in the storage cavity 2.

[0029] The elastic mechanism includes a connecting plate 5, which has a U-shaped structure as a whole. The inner sides of both ends of the two connecting plates 5 are connected to a clamping plate 8 through an elastic member. The elastic member is a spring 9. The two ends of the spring 9 are fixedly connected to the clamping plate 8 and the connecting plate 5 respectively. One end of the clamping plate 8 is clamped with the splint 1. An insert block 16 is provided on the side where the two clamping plates 8 face each other. An installation shaft 7 used in conjunction with the elastic mechanism is inserted between the two adjacent connecting plates 5, and the insert block 16 is clamped with the installation shaft 7.

[0030] A slot 12 is provided on the side of the clamping plate 1. A bent insert 18 is provided at the lower end of the clamping plate 8. The insert 18 is inserted into the slot 12. An upper baffle 13 is provided at one end of the insert 18, and the upper baffle 13 is arranged to fit the inner wall of the vertical plate 10. A lower baffle 14 is provided at the other end of the insert 18. The end of the lower baffle 14 fits the surface of the clamping plate 1. The end faces of the lower baffle 14 and the upper baffle 13 are both rounded. By clamping the clamping plate 8 into the slot 12 on the edge of the clamping plate 1, the two ends of the insert 18 are respectively against the surfaces of the clamping plate 1 and the vertical plate 10 through the upper baffle 13 and the lower baffle 14, and then the clamping plate 8 can be clamped to the clamping plate 1. At the same time, the end faces are set to rounded corners to facilitate detachment from the slot 12 during the ice breaking process, thereby achieving detachment of the device from the high-voltage line.

[0031] The upper part of the vertical plate 10 is provided with a hook portion 6, and a groove is provided in the hook portion 6. When the device is placed, the drone directly hooks the groove, thereby lifting the device and placing it on the wire.

[0032] Both ends of the vertical plate 10 are provided with holes 11, and the mounting shaft 7 is composed of two semicircular shafts. The mounting shaft 7 passes through the two holes 11 to connect the two vertical plates 10. The mounting shaft 7 is directly inserted into the holes 11, so that the two splints 1 can be connected together to form an integral structure.

[0033] The insert block 16 is clamped between the two semicircular shafts, and limit blocks 17 are provided on the upper and lower sides of the insert block 16. The limit blocks 17 are respectively clamped on the upper and lower sides of the mounting shaft 7. The insert block 16 is clamped between the semicircular shafts, and the upper and lower positions are limited by the limit blocks 17 to restrict and fix the two semicircular shafts.

[0034] The middle section of the connecting plate 5 is provided with an inwardly recessed portion 15, and the edges of the vertical plates 10 are also provided with rounded corners. The recessed portion 15 in the middle section of the connecting plate 5 facilitates the surface contact between the connecting plate 5 and the vertical plates 10, contributing to the stability of the structure. The rounded edges facilitate the separation of the connecting plate 5 from the clamping plate 1 when breaking ice.

[0035] When breaking ice on high-voltage lines, the drone can lift the device by hooking the hooks 6 on both sides, and directly set up the device on the wires that need to break ice. The lower end is connected to the counterweight block 4 through the connecting shaft 3, and the wire fits in the oblique part of the splint 1. When the device is set on the wire, the overall center of gravity is located below the storage cavity 2 due to the action of the counterweight block 4, so that it can be effectively and stably set up on the wire.

[0036] After the installation of the device is completed, the drone leaves the device and remotely controls the ignition of the safety explosive in the storage chamber 2 to break the ice. It should be noted that how to remotely detonate the safety explosive is not an improvement of the present invention. The specific detonation method can refer to the existing technology. Electric detonators can be used for detonation. At this time, the electric detonators need to be installed (glued or snapped) in the storage chamber 2 in the same way as the safety explosives. For example, referring to the electric detonators and safety explosives in the public document CN206370671U, the electric detonators disclosed in the comparative document have two-wire bidirectional non-polarity networking communication, which can realize in-hole setting and online calibration of a wide range (0 to 16000ms) and a small interval (1ms) delay time, thereby realizing remote control ignition. In the process of breaking ice, the impact of the safety explosive has an outward force on the splints 1 on both sides. Under the impact, the splint 1 will drive the card plate 8 and the vertical plate 10 to move to both sides at the same time, and the corresponding spring 9 will be compressed. The card plate 8 drives the plug 16, which is equivalent to the installation shaft 7, to move outward, and eventually the plug 16 will be separated from the installation shaft 7. After the plug 16 is separated from the installation shaft 7, there is an obvious gap between the two semicircular shafts, and the overall structure loses stability. The positions of the two vertical plates 10 will be offset, and the positions of the two splints 1 will also be offset. When the two splints 1 are dislocated under the impact of breaking ice, the elastic mechanism will also be affected, and the spring 9 It will be compressed under the impact force, and after compression, it will reset and stretch to push against the installation shaft 7 again. However, since the plug block 16 has been separated from the installation shaft 7, stretching again will inevitably apply force to other positions of the corners. In the process of stretching, the angle of the connecting plate 5 will be completely deflected. The card plate 8 is inserted into the hole 11 from the side of the splint 1. Under the action of impact and the resulting angle deviation, it is easy to detach from the hole 11. Finally, the elastic mechanisms at both ends will deviate to both sides and detach from the splint 1. The splint 1 will separate from each other without the restriction of the elastic mechanism and eventually fall from the high-voltage line. The ice on the surface of the transmission line will also be broken and detached from its surface under the action of the safety gunpowder.

[0037] After the ice-breaking operation is completed, the splint 1 and the elastic mechanism of the device will separate and fall off from each other. After the splint 1 and the elastic mechanism are assembled, they can be used again. It is only necessary to re-glue new ice-breaking safety explosives in the storage chamber 2, pass the installation shaft 7 through the hole 11 on the vertical plate 10, and then insert the plug 16 from the end of the installation shaft 7, and insert the plug 18 into the slot 12 from one side to complete the re-assembly of the device. The installation method is very simple and can be used repeatedly.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
