Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass insulator testing technology, and more specifically, to a glass insulator stress screening device. Background Technology
[0002] Glass insulators have a longer service life and better stability than ceramic insulators, and therefore have been widely used in recent years. Since glass insulators are made of tempered glass, they have internal stress during production, so it is necessary to screen and test their internal stress. Generally, glass insulator stress screening devices are mainly air-cooled, but existing air-cooled glass insulator stress screening devices have some problems and defects.
[0003] For example, during the screening and testing of glass insulators, broken glass insulators may not be completely separated from intact glass insulators, or broken glass insulator fragments may jump out of the device, causing injury to workers and accidents. If the cooling temperature is not low enough, unqualified glass insulators cannot be completely screened out. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a stress screening device for glass insulators, which can not only effectively separate broken glass insulator fragments, but also prevent glass residue from splashing and causing accidents when glass insulators with high stress break during the breaking process.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A stress screening device for glass insulators includes a support base and support columns respectively installed on both sides of the support base. A drive mechanism is installed on the support columns, and a track is installed on the drive mechanism. The track runs under the drive of the drive mechanism. A cold air blower is installed on the support base. The output end of the cold air blower is connected to a cold air delivery pipe, and the other end of the cold air delivery pipe is close to the lower surface of the track. An inclined plate is installed on the support columns to prevent broken glass insulators from jumping out.
[0007] Furthermore, a top bracket is installed at the upper end of the supporting column, a fan is installed on the upper side of the top bracket, and an mounting plate is installed on the lower side of the top bracket, with an air guide cover installed on the mounting plate.
[0008] Furthermore, the output end of the fan is connected to the air guide shroud.
[0009] Furthermore, the air outlet of the air guide shroud is located above the track.
[0010] Furthermore, the position of the air guide shroud facing the track is the same as the position of the cold air conveying pipe close to the track.
[0011] Furthermore, the track is provided with a mesh, the mesh aperture being smaller than that of a normal glass insulator but larger than that of fragments of a broken glass insulator.
[0012] Furthermore, a collection box is provided below the track.
[0013] Furthermore, the drive mechanism includes a drive motor mounted on a support column, the output end of the drive motor being connected to a rotating shaft, and a track being provided on the rotating shaft.
[0014] Furthermore, there are two sets of rotating shafts, with the motor driving the shafts to rotate, and the shafts driving the tracks to run.
[0015] Furthermore, the distance between the end of the cold air delivery pipe close to the lower surface of the track and the lower surface of the track is 2-5mm.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention employs simultaneous cooling of the upper and lower tracks, resulting in rapid temperature reduction. When the glass insulators arrive at this location, the temperature drops sharply. If the internal stress of the glass insulators does not meet the standards, they will break spontaneously upon encountering this temperature drop. The dual cooling of the tracks ensures that the temperature drops rapidly to a level suitable for inspecting the quality of the glass insulators. After the glass insulators break, fragments will splatter. The inclined plate prevents the broken glass insulators from scattering and causing accidents. A mesh is installed on the tracks, allowing broken glass insulators to fall through the mesh into the collection box during transportation, effectively separating qualified glass insulators from broken glass insulator fragments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0022] See attached document Figure 1 As shown, a stress screening device for glass insulators includes a support base 1 and support columns 2 respectively installed on both sides of the support base 1. A drive mechanism is installed on the support columns 2, and a track 3 is installed on the drive mechanism. The track 3 runs under the drive of the drive mechanism. A cold air blower 4 is installed on the support base 1. The output end of the cold air blower 4 is connected to a cold air delivery pipe 5. The other end of the cold air delivery pipe 5 is close to the lower surface of the track 3. An inclined plate 9 is installed on the support columns 2 to prevent broken glass insulators from jumping out.
[0023] A top bracket 6 is installed at the upper end of the support column 2. A fan 12 is installed on the upper side of the top bracket 6. An installation plate 7 is installed on the lower side of the top bracket 6. An air guide hood 8 is installed on the installation plate 7. The output end of the fan 12 is connected to the air guide hood 8. The air outlet of the air guide hood 8 is above the track 3. The position of the air guide hood 8 facing the track is the same as the position of the cold air conveying pipe 5 close to the track.
[0024] The cold air blown out of the blower 12 is directly blown onto the track 3 through the air guide 8, which lowers the surface temperature of the track 3. Since the glass insulator will only burst when the stress inside is unqualified, simply using the blower 12 to cool the track 3 is not enough to completely detect unqualified glass insulators. A cold air blower 4 is also installed below the track 3. The cold air blown out by the cold air blower 4 is blown onto the track through the cold air delivery pipe 5, and also blown onto the glass insulator through the mesh of the track, which lowers the temperature of the track. This causes the temperature of the glass insulator to drop rapidly. When the stress inside the glass insulator is relatively high, it will crack when the temperature drops rapidly, while qualified glass insulators will remain undamaged.
[0025] The distance between the end of the cold air delivery pipe 5 close to the lower surface of the track 3 and the lower surface of the track is 2-5mm. Through repeated experiments, setting the distance to 2-5mm not only does not affect the normal operation of the track 3, but also allows the temperature of the track 3 to drop rapidly. At the same time, the cold air that reaches the glass insulator through the mesh of the track 3 will not blow away the glass insulator on the track 3.
[0026] like Figure 2As shown, the track 3 is provided with a mesh, the mesh aperture is smaller than the size of a normal glass insulator but larger than the size of a broken glass insulator fragment. A collection box is provided below the track 3. The drive mechanism includes a drive motor 11 mounted on the support column 2. The output end of the drive motor 11 is connected to the rotating shaft 13. The track 3 is provided on the rotating shaft 13. There are two sets of rotating shafts 13. The drive motor 11 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the track 3 to run.
[0027] When using this invention, first place the glass insulator on the track 3, turn on the fan 12 on the top bracket 6 and the cold air blower 4 on the support base 1, start the drive motor 11, and the track 3 will start running, transporting the glass insulator to the position below the air guide shroud 8 and the location where the cold air delivery pipe 5 blows out. The combined force of the cold air from the air guide shroud 8 and the cold air from the cold air delivery pipe 5 causes the temperature of the glass insulator to drop sharply. If the stress inside the glass insulator is too high, it will burst when it encounters a sudden drop in temperature. Qualified glass insulators will remain undamaged. The fragments of the burst glass insulator will not bounce out due to the obstruction of the inclined plate 9 and will fall back onto the track 3. Because track 3 is made of rubber, it is elastic, so falling glass fragments will not damage qualified glass insulators. Track 3, made of rubber, is somewhat soft and not rigid, so it will sway slightly during operation. The swaying of track 3 will cause broken glass insulator fragments to slide from the grid on track 3 into the collection box 10 below track 3. Since the aperture of the grid on track 3 is smaller than the size of a normal glass insulator but larger than the size of broken glass insulator fragments, qualified glass insulators will not slide from the grid into the collection box 10 as track 3 reaches the designated position.
[0028] This invention employs a dual cooling mechanism, simultaneously blowing cold air from both above and below onto the track 3 to cool it rapidly. When the glass insulators arrive at this point, the temperature drops sharply. If the internal stress of the glass insulators does not meet the standards, they will break on their own due to the sudden temperature drop. The dual cooling of the track 3 ensures that the temperature of the track 3 drops rapidly to a level suitable for testing whether the glass insulators are qualified. After the glass insulators break, they will splatter. The inclined plate 9 prevents the broken glass insulators from splattering out and causing accidents. A mesh is set on the track 3, and the broken glass insulators fall through the mesh into the collection box 10 during transportation, effectively separating qualified glass insulators from broken glass insulator fragments.
