[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Reference Figures 1 to 5 According to an embodiment of the present invention, a cooling device for insulator production includes a cooling box 1, which is divided into an upper chamber 2 and a lower chamber 3. A rotating bracket 11 is provided in the upper chamber 2, and a positioning plate 12 for placing the insulator is provided on the rotating bracket 11. A temperature sensor 13 abutting against the insulator is provided on the positioning plate 12. A driving motor 14 connected to the rotating bracket 11 is provided in the lower chamber 3. Spray assemblies 15 for spraying water mist on the insulator are provided on the inner walls of the upper and lower ends of the upper chamber 2. A water tank 16 is provided at the side end of the cooling box 1. A water pump 17 connected to the spray assembly 15 is provided in the water tank 16. A controller 18 is provided on the cooling box 1. A fan 19 facing the positioning plate 12 is provided on the side wall of the upper chamber 2. The controller 18 is used to control the start and stop of the water pump 17, the driving motor 14 and the fan 19 according to the monitoring data of the temperature sensor 13.

[0026] The cooling device for insulator production according to an embodiment of the present invention places the insulator to be cooled on the positioning plate 12 on the rotating bracket 11, and then uses the spray assembly 15 to spray water mist on the upper and lower ends of the insulator to cool it, and starts the driving motor 14 to control the rotation of the rotating bracket 11, so that the water mist can be evenly attached to the insulator, which can not only improve the cooling speed of the insulator, but also ensure that the insulator is cooled evenly. The temperature sensor 13 on the positioning plate 12 can monitor the temperature of the insulator in real time. The controller 18 can control the water pump 17 to turn off when the temperature of the insulator drops to a certain value, and at the same time start the fan 19 to air-dry and cool the insulator. In conjunction with the rotating action of the rotating bracket 11, the fan 19 can only blow a single insulator on the rotating bracket 11, so as to avoid continuous positive blowing of one insulator causing the insulator to cool too quickly and affect its quality, so as to achieve pulsed slow cooling and air-drying of the insulator, which not only greatly shortens the cooling time of the insulator, but also ensures that the quality of the insulator will not be affected by the cooling rate, and effectively improves the production efficiency.

[0027] Specifically, when all the temperature sensors 13 monitor the initial temperature of the corresponding insulators, the controller 18 controls the drive motor 14 and the water pump 17 to start at the same time. After the insulator is cooled to a certain value, the controller 18 controls the water pump 17 to turn off, maintains the drive motor 14 on, and then starts the fan 19. The fan 19 quickly dries the insulator and can also cool the insulator. When the insulator drops to room temperature and is dried, the controller 18 controls the fan 19 to turn off, and then controls the drive motor 14 to turn off, completing the cooling process of the insulator; the opening time of the fan 19 can be known from multiple tests and will not be described in detail here; in this embodiment, the controller 18 is a single-chip microcomputer or a CPU, the drive motor 14 is a stepper motor, and the fan 19 is a conventional blower without a hot air function.

[0028] The rotating bracket 11 includes a rotating shaft 111 and multiple support rods 112. The lower end of the rotating shaft 111 is connected to the output shaft of the driving motor 14, and the support rods 112 are connected to the upper end side wall of the rotating shaft 111. The multiple support rods 112 are evenly distributed, and the support rods 112 are "L"-shaped. The positioning plate 12 is connected to the upper end of the vertical section of the support rod 112, and the number of the positioning plates 12 is consistent with the number of the support rods 112; the structure of the rotating bracket 11 enables it to place multiple insulators at the same time, which can not only cool multiple insulators at the same time, but also effectively improve the production efficiency. The structure of the support rods 112 can lift the positioning plate 12 to a certain height, and its even distribution around the rotating shaft 111 further ensures that the insulators on the positioning plate 12 can be evenly attached by water mist; in this embodiment, there are eight support rods 112 and eight positioning plates 12.

[0029] The positioning plate 12 includes a chassis 121 and a limiting column 122. The limiting column 122 is adapted to the central through hole of the insulator. The diameter of the chassis 121 is larger than the diameter of the limiting column 122. The temperature sensor 13 is embedded in the upper end surface of the chassis 121. The positioning plate 12 is made of silicone rubber. The chassis 121 is used to hold the insulator, and the limiting column 122 is used to limit the insulator to ensure that it can be stably placed on the positioning plate 12. When the insulator is placed on the positioning plate 12, the temperature sensor 13 can abut against the insulator, so that the temperature of the insulator can be monitored in real time, which provides a guarantee for the controllable cooling rate of the insulator. The silicone rubber material can increase the contact between the positioning plate 12 and the insulator. The friction of the insulator can prevent the insulator from shaking. At the same time, silicone rubber is soft and resistant to high temperature, will not wear out the insulator, will not be burned by the insulator, and has a long service life. In this embodiment, the chassis 121 and the limiting column 122 are an integrally formed structure, the height of the limiting column 122 is greater than the depth of the central through hole of the insulator. During specific implementation, the positioning plate 12 can be detachably connected to the support rod 112, and the matching positioning plate 12 is installed according to the size of different insulators. For example, a threaded shaft is set under the positioning plate 12, and the threaded shaft is embedded in the support rod 112 and threadedly connected to the support rod 112. The specific structure is well known to those skilled in the art, so it is not described in detail here.

[0030] The spray assembly 15 includes an annular tube 151 and a plurality of nozzles 152 connected to the annular tube 151, the nozzles 152 are evenly distributed on the annular tube 151, the annular tube 151 is respectively embedded in the top wall and the bottom wall of the upper cavity 2, the nozzles 152 respectively penetrate the top wall and the bottom wall of the upper cavity 2 and correspond to the positioning plate 12, and an atomizing nozzle 153 is provided at one end of the nozzle 152 away from the annular tube 151; a water main pipe 154 connected to the water pump 17 is provided on the water tank 16, a water branch pipe 155 is provided in the side wall of the upper cavity 2, both ends of the water branch pipe 155 are respectively connected to the two annular tubes 151, and one end of the water main pipe 154 is connected to the middle of the water branch pipe 155; the annular tube 151 is annular, and the outer diameter of the annular tube 151 is the same as the distance from the end of the support rod 112 away from the rotating shaft 111 to the center of the rotating shaft 111 The nozzle 152 corresponds to the positioning plate 12 one by one, and the atomizing nozzle 153 has a certain distance from the positioning plate 12, so as to ensure that the water mist can be evenly diffused to the insulator on the positioning plate 12. The annular tube 151 is embedded in the top wall and the bottom wall of the upper cavity 2, which can cool the upper cavity 2 and further improve the cooling rate of the insulator. The arrangement of the water delivery branch pipe 155 can ensure uniform water supply to the two spray assemblies 15, that is, uniform spraying of the upper and lower spray assemblies 15. In this embodiment, the upper end of the nozzle 152 of the lower spray assembly 15 has a certain distance from the bottom wall of the upper cavity 2, so as to avoid the atomizing nozzle 153 being submerged by the cooling water in the upper cavity 2. Specifically, the structure and principle of the atomizing nozzle 153 are well known to those skilled in the art, so they are not described in detail here.

[0031] The rotation speed of the rotating bracket 11 driven by the driving motor 14 is between 1RPM and 3RPM; if the rotation speed of the rotating bracket 11 is too fast, the water droplets attached to the surface of the insulator will be shaken off, and it is easy to cause the insulator to shake, or even fall off the positioning plate 12 and be damaged. In addition, if the rotation speed of the rotating bracket 11 is too fast, it will also affect the effect of the subsequent pulse-type slow cooling and drying of the insulator; in this embodiment, the rotation speed of the rotating bracket 11 driven by the driving motor 14 is 2RPM.

[0032] An exhaust hole 20 is provided on the top wall of the upper chamber 2, and a dustproof net 201 is provided at the exhaust hole 20; the exhaust hole 20 can discharge the water vapor in the upper chamber 2, so that the insulator is finally in a dry state, and the dustproof net 201 can prevent dust and other debris from falling into the upper chamber 2; in this embodiment, the exhaust hole 20 is located at one end of the top wall of the upper chamber 2 away from the fan 19, so that it can cooperate with the fan 19 to form convection and accelerate the drying rate of the insulator.

[0033] A baffle 21 is provided in the lower chamber 3 to seal the four sides of the drive motor 14. The upper and lower ends of the baffle 21 are respectively connected to the inner wall of the lower chamber 3, and the lower chambers 3 on the left and right sides of the drive motor 14 are interconnected. A collecting pipe 22 communicating with the upper chamber 2 is provided on the top wall of the lower chamber 3; an overflow pipe 23 communicating with the water tank 16 is provided on the side wall of the lower chamber 3 close to the water tank 16, and the overflow pipe 23 is located in the middle and upper part of the lower chamber 3, and the lower end of the collecting pipe 22 is located in the middle and lower part of the lower chamber 3; the baffle 21 can protect the drive motor 14 to prevent the drive motor 14 from being immersed in cooling water and affecting its service life, and the collecting pipe 22 can collect the cooling water in the upper chamber 2 to the lower chamber 3 The cooling water then gathers in the lower chamber 3 and finally flows back to the water tank 16 through the overflow pipe 23 for circulation, which can reduce the use of cooling water and reduce costs. In this embodiment, since there may be waste residue on the surface of the insulator, a filter is provided at the upper end of the collecting pipe 22 to prevent the waste residue and other debris in the upper chamber 2 from entering the lower chamber 3, and the lower end of the collecting pipe 22 is arranged at the middle and lower part of the lower chamber 3, so that part of the residue entering the lower chamber 3 can be deposited at the bottom of the lower chamber 3 and will not enter the water tank 16 through the overflow pipe 23. Finally, a filter element can be installed on the overflow pipe 23 to further ensure the purity of the recovered cooling water and provide protection for the recycling of cooling water.

[0034] An observation window 24 is provided on the front end side wall of the cooling box body 1 corresponding to the upper cavity 2. By providing the observation window 24, the surface state of the insulator can be conveniently observed, which is convenient for the staff to operate.
