Description

Technical Field

[0001] The invention belongs to the technical field of power transmission line maintenance, and in particular relates to a vibration deicing device for a power transmission line. Background Art

[0002] In some areas, transmission lines are affected by severe cold, rain and snow, resulting in ice covering the surface of the transmission lines, which increases the load on the transmission lines, makes it easy for the lines to break at the insulator connection area, and easily causes the poles to fall due to excessive load. Therefore, it is more important to remove ice from the transmission lines.

[0003] The invention patent, with authorization publication number CN113595007B, discloses a de-icing device and de-icing method for power transmission lines. The de-icing device includes an air compressor, a de-icer, and a drone. A traction rope and an insulated air pipe are connected to the de-icer. The drone is used to wrap the traction rope around the power transmission line and land on the ground. The traction rope is used to pull the de-icer under the power transmission line. The other end of the insulated air pipe is connected to the air compressor. The de-icer is provided with a piston, which is arranged at the top of the de-icer. The air compressor provides airflow to drive the piston to reciprocate. A controller assembly is provided at the connection between the insulated air pipe and the air compressor. The controller assembly is a PLC, which includes a PLC control unit and an execution unit. The controller assembly is provided with an interactive interface for operation. The execution unit includes a solenoid valve. The controller assembly is used to control the start and stop of the airflow output and the output volume. A guide device is provided on the upper surface of the de-icer. The guide device includes multiple guide posts, which are evenly arranged along the circumference of the piston. The guide device is used to guide the piston under the power transmission line.

[0004] When it is used, the staff on the ground use a drone to pull the traction rope to the top of the transmission line, and then land on the ground after circling it. The staff on the ground pulls the traction rope to pull the de-icer to the bottom of the transmission line, and then starts the air compressor. The air compressor provides airflow to drive the piston to reciprocate, and the piston continuously vibrates and impacts the transmission line to achieve de-icing operations.

[0005] However, this method of directly using an air compressor to supply air and achieve piston reciprocating impact is only suitable for de-icing transmission lines with thin ice thickness and close distances between towers. However, for transmission lines with thick ice, the de-icing force is insufficient and it is difficult to effectively shake off the ice layer. In addition, when the distance between towers is large, the ice on the transmission line has a mutual embedding effect, requiring a distributed ice destruction method. Therefore, in order to more effectively remove ice from transmission lines, it is necessary to provide a vibrating de-icing device that relies on compressed air as a power source, can provide more effective impact on the transmission line, and can also achieve distributed and segmented ice destruction on the transmission line.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 9 A vibration deicing device for power transmission lines includes a platform 1 made of ABS plastic and 5 cm thick; a stamping mechanism is installed on the middle side of the bottom of the platform 1, and a pressure column 7 is installed in the stamping mechanism. The pressure column 7 passes through the platform 1 and is connected to a support plate 9. The top of the support plate 9 is equipped with a punching head 10; When the punching mechanism instantly rushes in the compressed air, it drives the pressing column 7 to move upward instantly, so that the punching head 10 quickly hits the power transmission line.

[0020] Locking mechanisms are provided on both sides of the platform 1, which are used to hang on the power transmission line and perform anti-loosening locking and sealing; With the locking mechanism set, when the connecting frame 13 is hung on the power line, the connecting frame 13 is prevented from being separated from the power line.

[0021] The bottom of the punching mechanism is connected to an air supply control mechanism, which is also connected to a pressure gas tank 28. The air supply control mechanism is used to control the pressure of compressed gas into the pressure gas tank 28 and control the supply of compressed gas to the punching mechanism. After receiving the gas supply, the punching mechanism instantly pushes the pressure column 7 to push up the power transmission line. The pressure gas tank 28 is a 6.8L carbon fiber high-pressure gas tank coated with insulating paint. It stores compressed air, and the air pressure after the gas is injected into the pressure gas tank 28 is controlled by the air control mechanism. When the air supply control mechanism is controlled to release compressed air to the punching mechanism, the high-pressure compressed air in the pressure gas tank 28 is instantly discharged into the punching mechanism, pressing against the power transmission line on the column 7 to provide power.

[0022] A control mechanism is installed on the pressure gas tank 28; It also includes a distributed control device, which is used to perform delayed distributed control operations on multiple control mechanisms according to set numbers, and the control mechanism is used to control the locking and unlocking of the locking mechanism, and control the gas supply control mechanism to control the pressure of compressed gas to fill the pressure gas tank 28, and is also used to supply compressed gas into the stamping mechanism after receiving the operation instructions of the distributed control device.

[0023] Under such a setting, the distributed control device operates the selected multiple control mechanisms at a single time to realize distributed de-icing control.

[0024] See Figure 1 、 Figure 2 and Figure 6 The stamping mechanism includes a cylinder 2 fixed to the bottom of the table 1. The top of the cylinder 2 is fixed to the bottom of the table 1 by circumferentially distributed locking bolts 3. The top of the cylinder 2 and the bottom of the table 1 are both provided with press-in ring grooves. The inner wall of the press-in ring groove is pressed tightly by a sealing ring 4. The material of the sealing ring 4 is chloroprene rubber. Under such installation, the sealing ring 4 is pressed by the upper and lower press-in ring grooves and is clamped on the inner wall of the press-in ring groove, so that the cylinder 2 and the bottom of the table 1 have good sealing performance.

[0025] A sliding plug 5 is inserted into the cylinder 2, and a sealing ring 6 is embedded on the outer side of the sliding plug 5. The sealing ring 6 is made of graphite copper and slides in contact with the inner wall of the cylinder 2. In this arrangement, the sealing ring 6 and the inner wall of the cylinder 2 not only have a barrier property, but also have good lubrication. The top center position of the sliding plug 5 is screwed to the pressure column 7, and a spring 8 is provided on the pressure column 7. The spring 8 is a compression-rebound type. The two ends of the spring 8 are supported on the sliding plug 5 and the table 1 respectively. The initial compression-rebound force of the spring 8 is 6 Newtons, and the maximum compression-rebound force of the spring 8 is 14 Newtons.

[0026] Under the setting of spring 8, when the air supply control mechanism rushes compressed air into the lower space of the cylinder 2, the sliding plug 5 drives the pressure column 7 to move upward, and the spring 8 is compressed to the shortest state; when the air supply control mechanism stops rushing compressed air into the lower space of the cylinder 2 and controls the air release, the sliding plug 5 drives the pressure column 7 to move downward through the rebound force of spring 8 until the sliding plug 5 contacts the inner bottom of the cylinder 2.

[0027] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A plug post 11 is integrally provided at the bottom center of the impact head 10, and a column groove is provided at the bottom center of the support plate 9, and the plug post 11 is bonded in the column groove with resin glue. The plug post 11 and the impact head 10 are made of neoprene. A slot 12 is provided at the top of the impact head 10, and the slot 12 is a cross groove structure.

[0028] Under such an arrangement, when the transmission line is punched on the support plate 9, the punching head 10 forms a soft protection for the transmission line.

[0029] See Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The locking mechanism includes a connecting frame 13 screwed to the top of the table 1, and the connecting frame 13 is evenly coated with insulating paint. The connecting frame 13 is made of aluminum, and the top of the connecting frame 13 is tightly inserted into the soft cover 14. The material of the soft cover 14 is neoprene. The left and right sides of the bottom of the table 1 are screwed with mounting tubes 15. The material of the mounting tube 15 is ABS plastic. The bottom of the mounting tube 15 is screwed to fix the electromagnet 16. When the electromagnet 16 is energized, its upper part is the magnetic pole N pole; A magnetic block 17 is slidably inserted into the mounting tube 15 , the lower end of the magnetic block 17 is the N pole, the top of the magnetic block 17 is screwed to a sealing post 18 , the top of the sealing post 18 slides through the table 1 and is pressed against one end of the connecting frame 13 .

[0030] When the electromagnet 16 is energized, the magnetic block 17 is at the same level as the electromagnet 16 and drives the magnetic block 17 upward through the repulsive force. The upper end of the sealing column 18 presses one end of the connecting frame 13. When the electromagnet 1 loses power, the magnetic block 17 drives the sealing column 18 downward due to its own gravity, and the upper end of the sealing column 18 retracts into the table 1.

[0031] Before the de-icing device is mounted on the power line, the two connecting frames 13 are first tied with nylon ropes respectively, and the other ends of the nylon ropes are respectively tied to the sides of the landing gear of the drone. Before it is mounted on the power line, the electromagnet 16 is controlled to be de-energized, and the drone is controlled to rise to drive the de-icing device to rise. During the process, the telescope is used for observation, and the drone is controlled to drive the side opening of the connecting frame 13 to align with the power line and insert it into the power line. The electromagnet 16 is controlled to be energized, and the sealing column 18 moves up to buckle the connecting frame 13. When the de-icing device needs to be removed from the power transmission line, the drone is controlled to rise. When the de-icing device is lifted upward so that the side opening of the connecting frame 13 is aligned with the power transmission line, the electromagnet 16 is controlled to lose power. Then the drone is controlled to drive the side opening of the connecting frame 13 out of the power transmission line, and the drone is controlled to descend until the de-icing device falls to the ground, and the nylon rope is untied from the connecting frame 13.

[0032] See Figure 1 、 Figure 2 and Figure 6 The gas supply control mechanism includes a tee 19 that is sealed and screwed to the bottom of the cylinder 2. The right end of the tee 19 is sealed and screwed with an electromagnetic pressure relief valve 20. The electromagnetic pressure relief valve 20 is a normally open type and is closed by electricity. The lower end of the tee 19 is sealed and screwed with an electromagnetic valve 21. The electromagnetic valve 21 is a normally closed type and is opened by electricity. The lower end of the electromagnetic valve 21 is sealed and screwed with an electronic pressure gauge 22. The lower end of the electronic pressure gauge 22 is sealed and screwed with a tee 23. The upper port of the pressure gas tank 28 is sealed and screwed to one end of the tee 23. The right end of the tee 23 is screwed with an electromagnetic valve 24 that is normally closed and is opened by electricity. The right end of the electromagnetic valve 24 is screwed with a check valve 25. The inlet end of the check valve 25 is screwed with a joint 26. The joint 26 is installed with an air pipe 27. The air pipe 27 is an insulated compressed air pipe and is connected to the compressed air pump on the ground through the air pipe 27.

[0033] The compressed air pump is connected to the air pipe 27 by a quick-release air joint. Under such an arrangement, a single compressed air pump is sufficient to inflate the pressure gas tanks 28 on multiple de-icing devices.

[0034] There are three control modes: Mode 1: Control the electromagnetic pressure relief valve 20 to open, the electromagnetic valve 1 21 to close, the electromagnetic valve 2 24 to open, the punching mechanism to deflate, and the pressure tank 28 to start inflating. The electronic pressure gauge 22 measures the pressure of the gas injected into the pressure tank 28, and the control mechanism monitors the pressure of the injected gas. When the set pressure threshold is reached, the electromagnetic valve 2 24 is controlled to close. Mode 2: Keep controlling the solenoid valve 2 24 closed, control the solenoid pressure relief valve 20 closed, open the solenoid valve 1 21 for 2 seconds, and then control the solenoid valve 1 to close; Mode three: the electromagnetic pressure relief valve 20 is controlled to open, and the electromagnetic valve 1 21 and the electromagnetic valve 2 24 are controlled to close.

[0035] In the two control modes, the pressure gas tank 28 is depressurized and inflated, and the pressure gas is instantly supplied to the punching mechanism.

[0036] Therefore, the compressed air is released instantaneously from the pressure gas tank 28, providing more effective impact kinetic energy for the punch head 10. When the punch hits the transmission line, the transmission line area is impacted and vibrates, and the ice on the surface is effectively peeled off.

[0037] See Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 The control mechanism includes a mounting hoop 29 fixed to the pressure gas tank 28 by bolts. The right side of the mounting hoop 29 is connected to a control box 31 through a connector 30. The mounting hoop 29, the connector 30 and the control box 31 are injection-molded integral parts. A development board 32 is provided on one side of the control box 31. A battery box is installed on the right side of the control box 31, housing Battery 1 (33). A charger (34) is bolted to the side of the control box 31. The power output of the charger (34) is connected to the power input of Battery 1 (33) via a cable. The power output of the charger (34) is connected to a charging head, which is embedded in the right side of the control box 21 and connected to a charging cable. An integrated relay (35) is screwed to the lower portion of Battery 1 (33) within the control box 31. The power output of Battery 1 (33) is connected to the power input of the integrated relay (35) via a cable.

[0038] Each control point output end of the integrated relay 35 is connected to the power input end of the electromagnet 16, the electric control input end of the electromagnetic pressure relief valve 20, the electric control input end of the electromagnetic valve 1 21 and the electric control input end of the electromagnetic valve 2 24 through cables.

[0039] See Figure 8The development board 32 includes a wireless signal transceiver module 1, which is bidirectionally connected to a numbering module. The numbering module is used to accept external numbering operations, and the wireless signal transceiver module 1 sends out the number it has programmed. Under such a setting, the numbering module can not only store the edited number, but also change it through the distributed control device. Among them, the numbering module only allows 16 characters to be programmed, and more or less characters will not be entered. The front character is a change character, which can be entered as 0, 1, or 2, where 0 represents relay control module 2, relay control module 3, and relay control module 4. The control module 4 is shut down, 1 represents operation mode 1, 2 represents operation mode 2, the second character is also a conversion character, which can be input T or R, where T represents power on of the relay control module 1, and R represents power off of the relay control module 1. The remaining 14 characters are used for random programming; the wireless signal transceiver module 1 is also connected to a signal processing module, which is used to convert the control signal received by the wireless signal transceiver module 1. During the conversion process, the last 14 digits of the number stored in the number programming module are matched with the last 14 digits of the received number. If the match is unsuccessful, a signal is sent through the wireless signal transceiver module 1. The prompt of unsuccessful matching is also used to receive the air pressure value signal of the electronic pressure gauge 22 to judge the critical pressure value. If the critical pressure value is reached, the signal processing module sends an instruction to close the solenoid valve 2 24 to the logic import module. If it is lower than the critical pressure value, the signal processing module sends an instruction to close the solenoid valve 2 24 to the logic import module. When the second character is T, the relay control module 1 sends an instruction to connect the electromagnet 16. When the second character is R, the relay control module 1 sends an instruction to disconnect the electromagnet 16. The signal processing module is connected to the logic import module, and the logic import module is connected to the relay control module 1. , relay control module 2, relay control module 3 and relay control module 4, the logic import module is used to identify the converted control signal, the identification process is the judgment process of the first two digits of the number, which are stored in the control mode of the two major control modes of the relay control module 1 on-off operation control mode and the relay control module 2, relay control module 3 and relay control module 4. Each control mode corresponds to a set number in advance. When judging, the first two digits of the number are matched with the number of each control mode respectively, and input into the relay control module 1, relay control module 2, relay control module 3 and relay control module 4 respectively according to the control mode; When mode 1 corresponding to number 1 is running, relay control module 2 issues a power-off instruction, relay control module 3 issues a power-off instruction, and relay control module 4 issues a power-on instruction. If the pressure critical value is reached, relay control module 4 issues a power-off instruction. When mode 2 corresponding to number 2 is running, the relay control module 4 keeps issuing the power off instruction, the relay control module 2 issues the power on instruction, the relay control module 3 issues the power on instruction for 2 seconds, and then issues the power off instruction; When mode three corresponding to number 3 is running, relay control module two, relay control module three and relay control module four issue a power-off instruction; When the control mode corresponding to number T is running, the relay control module issues a command to turn on the power supply; When the control mode corresponding to number R is running, the relay control module issues an instruction to disconnect the power supply.

The operation signal receiving module receives the number input by the industrial computer 105, and the column allocation module allocates the number and sends it out through the wireless signal transceiver module 2 with a delay. The industrial computer 105 sets the delay time for the two adjacent groups of allocations. The operation signal receiving module also receives the number programmed by the industrial computer 105, and the column allocation module allocates the number and sends it out through the wireless signal transceiver module 2 to modify the number pre-stored in each number programming module.

[0045] Therefore, under such a setting, the numbers stored in the numbering module of multiple de-icing devices can be modified, and the first two digits of the numbers can be edited according to control requirements. Therefore, when all de-icing devices are mounted on the transmission line, the de-icing devices are distributed controlled by the distributed control device.

[0046] Due to the use of distributed control, multiple sections of the transmission line can be impacted at the same time, and this impact method can be delayed multiple times, effectively destroying the embedded state of ice in the corresponding section of the transmission line, and the de-icing effect is better.

[0047] The working principle of this embodiment is as follows: when the connecting frames 13 of all de-icing devices are hung on the transmission line by nylon ropes pulled by drones, and the locking mechanism is controlled by the distributed control device to complete the locking, the operation number is set by the distributed control device and is issued with a delay, so that multiple sections of positions on the transmission line can be impacted at the same time, and this impact method can be delayed multiple times, effectively destroying the embedded state of ice on the corresponding section of the transmission line, and the de-icing effect is better.

[0048] During the vibration deicing process, the air supply control mechanism controls the pressure gas tank 28 to be filled with compressed air of a set pressure value. After the control mechanism receives the numbered instruction, the air supply control mechanism instantly charges the high-pressure air in the pressure gas tank 28 into the punching mechanism, which drives the pressing column 7 to rush upward rapidly, causing the punching head 10 to rush upward at high speed to the transmission line. The transmission line area is impacted and vibrates, and the ice on the surface is effectively peeled off. The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
