Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable erection device, in particular to a cable erection device for cold regions. BACKGROUND

[0002] In the cold region environment, after the cable is erected, snowfall in winter is easy to accumulate on the surface of the cable. The continuous accumulation of snow will continuously increase the carrying weight of the cable. When the weight exceeds the bearing limit of the cable, it is easy to cause the cable to break, thereby causing power interruption accidents. At the same time, the ice formed by the melting of the snow will further increase the carrying burden of the cable, which seriously threatens the safety and stability of power transmission.

[0003] Most of the existing cable erection devices only have basic cable support and guiding functions, and lack effective snow removal mechanisms for cold regions. Some simple snow removal devices have problems such as complex structure, high energy consumption, poor snow removal effect, etc., and are difficult to automatically trigger snow removal action according to the weight of the snow, and cannot realize intelligent and precise snow removal. In addition, the environment in cold regions is harsh, and the stability of external power supply is poor. The traditional snow removal device relying on external power supply cannot work normally in the case of power failure, further reducing the reliability of the cable erection in cold regions.

[0004] Therefore, in view of the special environmental requirements in cold regions, a cable erection device with automatic snow weight detection, precise snow removal action triggering, low energy consumption, high reliability and convenient installation and maintenance is designed to solve the problems of lack of effective snow removal mechanism, high energy consumption, poor reliability and low adaptability of existing devices. It has become a technical problem to be solved to ensure the safety of power transmission in cold regions and improve the stability of power supply. SUMMARY

Optimize the structure design of the device to improve the structural stability and component reliability in low temperature environment and prolong the service life. 4. Simplify the cable installation and maintenance process, improve the work efficiency, and reduce the risk of outdoor work in cold regions.

Connect the output end of the storage battery 270 to the voltage stabilizing module 320, connect the output end of the voltage stabilizing module 320 to the control module 280 to supply power to the control module 280. Connect the control module 280 to the driving motor 210 and the pressure switch 141 through wires to realize signal transmission and control. After the connection is completed, check whether the wire connection is firm and whether the insulation layer is intact to ensure that there is no short circuit and open circuit hidden danger.

[0042] 6. Debugging: After installation, debugging is carried out: first, check the flexibility of each mechanical part, manually turn over the upper bearing table 110 to ensure smooth opening and closing. Turn the crankshaft 240 to ensure that the transmission parts are not jammed. Then debug the electrical system, start the photovoltaic panel 290 power supply, check the charging status of the battery 270, and whether the control module 280 is working normally. Simulate the weight of the accumulated snow, place a 5kg weight on the cable 170, check whether the pressure switch 141 is triggered, whether the drive motor 210 is normally started, and whether the vibration frame 251 drives the cable 170 to reciprocate. Remove the weight and check whether the drive motor 210 is normally stopped. After debugging is completed, the device can be put into use.

[0043] Referring to Figures 1-5 The working principle of the present application is as follows: The working process of the present application mainly includes three stages: energy supply, snow detection and automatic snow removal, which are coordinated to realize automatic snow removal protection of the cable 170 in cold regions: 1. Energy supply stage: During the day, the photovoltaic panel 290 converts solar energy into electrical energy under sunlight, and the electrical energy is transmitted to the voltage conversion module 310 in the control box 300 through the wire. The voltage conversion module 310 converts the unstable voltage output by the photovoltaic panel 290 into a standard charging voltage of 14.4V, and charges the battery 270. At the same time, part of the electrical energy output by the voltage conversion module 310 is stabilized to 5V by the voltage stabilizing module 320, and is supplied to the control module 280 to ensure that the control module 280 is in working condition at any time. At night or when there is insufficient light, the photovoltaic panel 290 cannot generate electricity normally, at this time the battery 270 begins to discharge to supply power to the control module 280 and the drive motor 210, realizing continuous energy supply and ensuring stable operation of the device at all times.

[0044] 2. Snow detection stage: When it snows in cold regions in winter, snowflakes continue to accumulate on the surface of the cable 170, and the weight of the accumulated snow gradually increases. The weight of the accumulated snow is transmitted to the guide roller 161 through the cable 170, the guide roller 161 transmits the pressure to the roller mounting bracket 160, the roller mounting bracket 160 moves downward under the action of the pressure, drives the damping rod 151 to compress, the damping rod 151 pushes the pressure plate 152 to move downward, and the pressure plate 152 applies pressure to the diaphragm of the pressure switch 141. With the increase of the amount of snow, the pressure gradually increases, when the pressure reaches the preset threshold value (5kg) of the pressure switch 141, the contacts inside the pressure switch 141 are closed, a high-level signal is sent to the control module 280, and the control module 280 receives the signal and immediately enters the snow removal preparation state.

[0045] 3. Automatic Snow Removal Stage: After receiving the trigger signal from the pressure switch 141, the control module 280 immediately outputs a control signal to the drive motor 210, controlling the drive motor 210 to start. The output shaft of the drive motor 210 drives the drive wheel 220 to rotate, and the drive wheel 220 drives the driven wheel 230 to rotate synchronously via a V-belt. The driven wheel 230 drives the crankshaft 240 to rotate. During the rotation of the crankshaft 240, its eccentric structure drives the drive rod 250 to reciprocate. The drive rod 250 drives the vibrating frame 251 to reciprocate linearly along the axial direction of the cable 170. The vibrating frame 251 drives the cable 170 to vibrate synchronously via the connecting frame 171. The vibration frequency is 12Hz and the amplitude is 6mm. Under the action of vibration inertia, the snow on the surface of the cable 170 quickly falls off, preventing the continuous accumulation of snow. Once the snow has fallen, the weight of cable 170 returns to normal. The pressure of pressure plate 152 on pressure switch 141 gradually decreases. When the pressure falls below a preset threshold, the contacts inside pressure switch 141 open, and control module 280 receives no signal. It then outputs a control signal to drive motor 210, stopping it and completing one automatic snow removal cycle. If snow accumulates again, the device will repeat the snow detection and removal process to continuously protect cable 170.
