Description

Technical Field

[0001] The invention relates to the technical field of hollow column explosion-proof devices, in particular to an injection explosion-proof device for a hollow composite insulator. Background Art

[0002] Traditional porcelain insulators have drawbacks such as explosion susceptibility and heavy weight. Hollow composite insulators, however, utilize epoxy resin-impregnated fiberglass wrapped tubing encapsulated in a silicone rubber sheath. These insulators combine lightweight design with impact resistance. High-temperature vulcanized silicone rubber sheaths are bonded to the outer wall of the insulation tube to form a continuous protective layer, addressing the degradation of insulation performance associated with environmental erosion in traditional porcelain sheaths. Hollow composite insulators have evolved from early suspension structures to a full product line covering AC / DC voltages from 750kV to 1100kV. These insulators are also suitable for diverse scenarios, including GIS bushings and substations, achieving full coverage from power distribution to ultra-high voltage transmission. When drilling a hollow cylinder, the contact between the drill bit and the hollow body will generate radial force and vibration, which will cause micropores or incompletely cured epoxy resin areas to expand into through holes, causing damage to the hollow cylinder structure, reducing the sealing performance and the mechanical strength of the hollow cylinder, increasing the rework rate and production costs.

[0003] Patent CN116230329B discloses a composite insulator and injection molding process.

The switching valve 46 is connected to the controller 11 through a signal line. The atomizing nozzle 43 and the pressurizing nozzle 44 are connected to the water tank 35 through the switching valve 46 and the guide pipe 45.

The controller 11 compares the temperature and humidity information with the preset values. The temperature range is 5°C to 40°C, and the humidity should be lower than 80%. When the temperature is too low, the hollow cylinder is prone to microcracks due to its low-temperature brittleness. In a low-temperature environment, the plasticity of the material is reduced, resulting in the inability to effectively release stress during punching, resulting in cracking at the edge of the hole wall. Excessive temperature will increase the risk of thermal deformation. Excessive humidity will cause stratification of the punching edge or expansion of microcracks in the hole wall. If the humidity is too low, it is necessary to pay attention to the possible generation of static electricity. When the temperature is too high or the humidity is too high, the fan 22 is driven by the support motor 10 to rotate, thereby accelerating the air circulation inside the hollow cylinder and reducing the temperature and humidity. When the temperature is too low, the electrical energy in the heat storage chamber 19 is converted into heat energy through the output unit 33 to heat the internal space of the hollow cylinder. At the same time, the fan 22 is driven by the support motor 10 The fan 22 rotates to uniformly increase the temperature inside the hollow column.

When drilling, the fan 22 is driven to rotate by the support motor 10 to generate suction to drive the debris generated by the drilling into the storage chamber 21 through the air outlet 25. Different impurities in the debris can be separated by the filter 23, and the reusable debris can be collected together, reducing resource waste, realizing the function of controlling the internal environment of the hollow column, solving the problems of thermal expansion, hygroscopic expansion, accelerated aging and structural blockage of the hollow column, reducing the risk of deformation of the hollow column, avoiding the impact of debris on subsequent processing, improving the product qualification rate, and extending the service life of the product under complex working conditions.

[0027] Example 5: Please refer to Figure 1 、 Figure 2 and Figure 6 , a hollow composite insulator injection explosion-proof device, the push rod 4 is provided with a rotating assembly 3 on the right side of the outer wall, the rotating assembly 3 is connected to the controller 11 through a signal line, and the controller 11 is provided in the middle of the inner wall of the rotating assembly 3; The rotating assembly 3 includes: a holder 12, a rotating gear 13, a photoelectric sensor 14 and a rotating shaft 15. The holder 12 is connected to the controller 11 via a signal line, the rotating gear 13 is connected to the photoelectric sensor 14 via a signal line, and the rotating gear 13 is connected to the support motor 10 via a connecting shaft. By canceling the fixation of the rotating gear 13 by the holder 12, the supporting motor 10 drives the rotating gear 13 to rotate on the rotating shaft 15, driving the inner support plate 8 to rotate, and the rotation angle of the rotating gear 13 is detected and controlled by the photoelectric sensor 14. A rotating shaft 15 is mounted on the right side of the outer wall of the push rod 4, a rotating gear 13 is mounted on the upper side of the outer wall of the rotating shaft 15, a holder 12 is mounted on the right side of the outer wall of the rotating gear 13, and a photoelectric sensor 14 is mounted on the upper side of the outer wall of the holder 12; The outer support plate 9 includes: support pieces 2 and positioning holes 7. The outer support plate 9 is composed of support pieces 2. There are gaps between the support pieces 2. The positioning holes 7 are set in the middle of the inner wall of the support piece 2. Furthermore, when drilling, if the positioning is inaccurate, the performance of the hollow column will be reduced, and the drilling position on the surface of the hollow column needs to be positioned. After the operator places the hollow column, the inner support plate 8 and the outer support plate 9 support and fix the control column. After completing one hole drilling, the controller 11 cancels the fixation of the rotating gear 13 by the fixer 12, and the rotating gear 13 is driven by the support motor 10 to rotate on the rotating shaft 15. At the same time, the rotation angle of the rotating gear 13 is detected by the photoelectric sensor 14. After rotating to the required angle, the support motor 10 stops driving the rotating gear 13 and restores the fixing effect of the fixer 12 on the rotating gear 13. During the rotation process, the inner support plate 8 and the outer support plate 9 rotate synchronously. After the rotation is completed, auxiliary positioning is performed through the positioning hole 7 on the outer support plate 9, so as to achieve the effect of accurately controlling the drilling position, avoiding the reduction of structural stability caused by uneven hole spacing, improving processing efficiency, and increasing the service life of the prepared hollow composite insulator and reducing maintenance costs.

[0028] Working principle: When performing the hollow cylinder punching operation, the controller 11 controls the support motor 10 to drive the lifting rod 29 to lift the first support block 27, so that the first support block 27 lifts the outer support plate 9, and the second support block 28 remains stationary. After the infrared sensor 1 detects that the operator has placed the hollow cylinder, the information is transmitted to the support motor 10, and the support motor 10 drives the lifting rod 29 to lower the lifting height of the first support block 27, so that the support piece 2 of the outer support plate 9 is attached to the outer wall of the hollow cylinder. The support motor 10 drives the lifting rod 29 to lower the lifting height of the first support block 27, so that the support piece 2 of the outer support plate 9 is attached to the outer wall of the hollow cylinder. The rotating nut 6 is rotated to push the push rod 4, so that the push block 5 contacts the inner support plate 8. The support motor 10 drives the lifting rod 29 to lift the second support block 28, and the support piece 2 of the inner support plate 8 is attached to the inner wall of the hollow column to complete the support and fixation of the hollow column. When the support motor 10 drives the lifting rod 29 to raise the height of the second support block 28, the pressure of the inner support plate 8 on the inner wall of the hollow column is detected by the pressure sensor 30 to ensure that the pressure applied by the inner support plate 8 on the inner wall of the hollow column is within the range of 0.5kN to 1kN; After the operator places the hollow cylinder, the inner support plate 8 and the outer support plate 9 support and fix the control cylinder, and after completing a hole drilling, the controller 11 cancels the fixation of the rotating gear 13 by the fixer 12, and the supporting motor 10 drives the rotating gear 13 to rotate on the rotating shaft 15, driving the inner support plate 8 and the outer support plate 9 to rotate synchronously. At the same time, the rotation angle of the rotating gear 13 is detected by the photoelectric sensor 14. After rotating to the required angle, the supporting motor 10 stops driving the rotating gear 13 and restores the fixing effect of the fixer 12 on the rotating gear 13. After the rotation is completed, the positioning is assisted by the positioning hole 7 on the outer support plate 9. The operator drills the hollow cylinder. During the drilling process, the drill bit contacts the hollow cylinder and rotates at high speed, generating heat and vibration. The shock absorber 18 arranged on the side where the inner support plate 8 and the outer support plate 9 contact the hollow cylinder eliminates vibration, transfers heat to the absorption unit 32 through the heat conductive layer 31, and the absorption unit 32 transfers the heat to the heat storage chamber 19 through the heat transfer pipe 34, and converts the heat into electrical energy for storage. During the drilling process, the temperature of the drilling position of the hollow cylinder is detected by the temperature sensor 16, and the information is transmitted to the controller 11. The controller 11 compares the received temperature information with the preset range. After the heat is absorbed and converted by the heat component 17, if the temperature still exceeds the set value, the fan 22 is driven by the support motor 10 to rotate to accelerate the air circulation inside the hollow cylinder. After the drilling is completed, the heat storage chamber 19 is connected through the output unit 33 to maintain the temperature of the drilling position, thereby reducing the generation of thermal stress. When punching holes at both ends of the hollow column, the hollow column is deformed due to operational errors, which affects the use of the hollow column. The operator places the deformed position on the support module and supports and fixes the hollow column by adjusting the inner support plate 8 and the outer support plate 9. The controller 11 controls the output units 33 of the inner support plate 8 and the outer support plate 9 to connect to the heat storage chamber 19 to convert electrical energy into thermal energy to heat the deformed position. During the heating process, the temperature of the deformed position is detected by the temperature sensor 16 to ensure that the temperature is within the set range. After heating to the set temperature, the controller 11 controls the lifting rod 29 to lower the lifting height of the first support block 27 and increase the lifting height of the second support block 28, and monitors the pressure applied by the push block 5 to the hollow column through the pressure sensor 30. , to correct the deformed position of the hollow cylinder. During the correction process, the controller 11 releases the fixation of the rotating gear 13 by the fixer 12, and drives the rotating gear 13 to rotate on the rotating shaft 15 through the support motor 10, thereby driving the inner support plate 8 and the outer support plate 9 to rotate, thereby avoiding the asymmetric material flow caused by unilateral rotation, reducing the shear stress gradient between the fiber reinforcement layer and the resin matrix, and shortening the correction cycle. After the correction is completed, the fan 22 is driven by the support motor 10 to rotate to accelerate the gas circulation inside the hollow cylinder and accelerate the cooling. The controller 11 controls the switching valve 46 to connect the atomizing nozzle 43, the guide pipe 45, the water valve 37 and the water tank 35, and switches the pressurized nozzle 36 to the atomizing mode to spray water on the correction area, and realize rapid cooling of the correction area by evaporation and heat absorption; When the hollow cylinder is being punched and corrected, the temperature and humidity inside the hollow cylinder are detected by the temperature sensor 16 and the humidity sensor 26, and the temperature and humidity information is transmitted to the controller 11. The controller 11 compares the temperature and humidity information with the preset values. When the temperature is too high or the humidity is too high, the fan 22 is driven by the support motor 10 to rotate, thereby accelerating the air circulation inside the hollow cylinder and reducing the temperature and humidity. When the temperature is too low, the electrical energy in the heat storage chamber 19 is converted into thermal energy through the output unit 33 to heat the internal space of the hollow cylinder. At the same time, the fan 22 rotates under the drive of the support motor 10 to even out the temperature inside the hollow cylinder. The humidity rises evenly. When the humidity is too low, the atomizing nozzle 43 and the water tank 35 are connected by controlling the switching valve 46, and the water flow in the water tank 35 is atomized and sprayed out, assisted by the rotation of the fan 22 for uniform humidification. After the drilling is completed, the pressurized nozzle 44 and the water tank 35 are connected by controlling the switching valve 46, and the water flow in the water tank 35 is pressurized and sprayed out to clean the drilling position and the inside of the hollow cylinder. When drilling, the fan 22 is driven to rotate by the support motor 10 to generate suction to drive the debris generated by the drilling into the storage chamber 21 through the air outlet 25, and different impurities in the debris can be separated by the filter 23, and the reusable debris is collected together.
