Description

Technical Field

[0001] This utility model belongs to the technical field of glass insulator production equipment, and in particular relates to a cooling pool on a glass insulator thermal shock line. Background Technology

[0002] Glass insulators play a crucial insulating role in power systems, and their performance directly affects the safety and stability of power transmission. In actual operating environments, glass insulators frequently encounter drastic temperature changes, such as diurnal temperature variations, seasonal changes, and sudden weather events. Thermal shock treatment is a core step in verifying the quality of glass insulators. By accurately simulating extreme temperature change scenarios that may occur in actual use, it is possible to efficiently detect latent defects inside the glass insulators, such as microcracks and bubbles. These defects may not immediately cause insulator failure under normal operating conditions, but under drastic temperature fluctuations, they will rapidly expand due to thermal expansion and contraction, ultimately leading to insulator damage and potentially causing serious power accidents. Therefore, conducting rigorous and effective thermal shock treatment on glass insulators to ensure their sufficient resistance to temperature changes is a key measure to guarantee the safe and reliable operation of power systems.

[0003] Currently, the cooling tanks on glass insulator thermal shock production lines generally use conveyors to slowly transport glass insulators to complete the thermal shock treatment. Specifically, the conveyor operates at a relatively constant and slow speed, resulting in insufficient thermal shock intensity. In view of the problems existing in the cooling tanks on current glass insulator thermal shock production lines, this invention aims to design a completely new cooling tank.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a cooling pool on the thermal shock line of a glass insulator, which effectively improves the thermal shock strength of the glass insulator through innovative structural design and advanced control methods.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a cooling pool for a glass insulator's hot and cold impact line, comprising a rectangular water pool, a slide installed from one end to the middle of the water pool, with the upper end of the slide positioned above the end of the water pool; a pusher roller is also installed in the middle of the water pool; the slide includes a row of evenly arranged four-section round rods; the lower part of the row of four-section round rods is connected as one unit by several crossbars, and the ends of the crossbars are fixed to the inner wall of the water pool; the portion of the row of four-section round rods protruding from the water pool is connected as one unit below by slats; a protective plate extending towards the protruding end of the four-section round rods is fixed to the end face of the water pool; the ends of the slats are fixed to the protective plate.

[0007] As a preferred technical solution of this utility model, the four-section round rod is divided into a first slope section, a second slope section, a third slope section and an arc section from top to bottom, and there is an arc transition between adjacent two slope sections; the inclination of the first slope section, the inclination of the second slope section and the inclination of the third slope section increase sequentially.

[0008] As a preferred embodiment of this utility model, the upper ends of a row of four-section round rods are fixed on the same first arc transition plate; the first arc transition plate is tangent to the connection point of the upper ends of the four-section round rods.

[0009] As a preferred embodiment of this utility model, the lower ends of the row of four-section round rods are fixed on the same second arc transition plate; the second arc transition plate is tangent to the connection point of the upper end of the four-section round rods.

[0010] As a preferred embodiment of this utility model, the push roller includes a main shaft that is sealed and installed between the side walls of the water tank; three axially arranged push plates are evenly installed on the portion of the main shaft located inside the water tank; a motor for driving the main shaft to rotate is installed on the outer wall of the water tank; and the push plates cooperate with the arc segment.

[0011] As a preferred embodiment of this utility model, a connecting water pipe is installed between the two ends of the water tank; a circulation pump is installed on the connecting water pipe.

[0012] As a preferred technical solution of this utility model, the four-section round rod is made of smooth stainless steel, and a Teflon coating can also be applied to the surface of the stainless steel.

[0013] This utility model has the following beneficial effects: This invention abandons the slow conveyor method of the original and adopts a design combining a slide carriage and a pusher roller. After the glass insulator slides into the water tank from the slide carriage, it is quickly and orderly pushed to different areas by the pusher roller for thermal shock treatment, which greatly enhances the thermal shock strength and can more effectively test the performance of the glass insulator, thereby improving product quality.

[0014] The tilting design of the slide and the precise pushing of the pusher rollers in this invention increase the movement speed of the glass insulators in the water tank, enabling more glass insulators to be processed per unit time, significantly improving overall production efficiency and meeting the needs of large-scale production.

[0015] The tilt angle of this utility model slide has been precisely calculated and verified through multiple tests. The guard plate is made of high-strength, corrosion-resistant, and smooth alloy material and is polished. The curvature radius of the first and second arc transition plates is customized according to the glass insulator. These detailed designs ensure that the glass insulator slides smoothly and steadily during the transition, reducing scratches and other damage caused by collisions and friction, and ensuring the appearance and internal quality of the product.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1 Please see Figure 1-6 As shown, this utility model is a cooling pool for the thermal shock line of glass insulators. It aims to replace the original method of slowly conveying glass insulators with a conveyor in a water pool to subject them to thermal shock by optimizing the structure, thereby strengthening the thermal shock intensity and improving production efficiency and product quality.

[0027] The structure includes a rectangular water tank 1 and a slide 2 installed from one end to the middle of the water tank 1, with the upper end of the slide 2 positioned above the end of the water tank 1. A push roller 3 is also installed in the middle of the water tank 1. The slide 2 includes a row of evenly arranged four-section round rods 21. The row of four-section round rods 21 is connected as one unit below by several crossbars 22, and the ends of the crossbars 22 are fixed to the inner wall of the water tank 1. The portion of the row of four-section round rods 21 protruding from the water tank 1 is connected as one unit below by slats 23. A protective plate 24 extending towards the protruding end of the four-section round rods 21 is fixed to the end face of the water tank 1. The ends of the slats 23 are fixed to the protective plate 24. The protective plate 24 is made of high-strength, corrosion-resistant alloy material, and its surface is polished to be smooth and flat, preventing scratches caused by friction between the glass insulator and the protective plate 24 during the sliding process, which would affect product quality.

[0028] The four-section circular rod 21 is divided into a first slope section, a second slope section, a third slope section, and an arc section from top to bottom, with an arc transition between adjacent slope sections. The inclination of the first slope section, the second slope section, and the third slope section increases sequentially. The glass insulator is fed to the first slope section of the four-section circular rod 21 via an input conveyor. Then, the glass insulator accelerates and slides into the water in the pool 1 via the second slope section. It continues to accelerate on the third slope section and then changes direction at the arc section, sliding to the output conveyor where it is carried away from the pool 1.

[0029] The upper ends of a row of four-section round rods 21 are fixed to the same first arc-shaped transition plate 25. The first arc-shaped transition plate 25 is tangent to the upper end of the four-section round rods 21 at its connection point. The lower ends of a row of four-section round rods 21 are fixed to the same second arc-shaped transition plate 26. The second arc-shaped transition plate 26 is tangent to the upper end of the four-section round rods 21 at its connection point. The radii of curvature of the first arc-shaped transition plate 25 and the second arc-shaped transition plate 26 are customized according to the size of the glass insulator and the sliding speed to ensure a smooth transition when the glass insulator enters and leaves the slide 2, reducing the impact of impact on the glass insulator.

[0030] The push roller 3 includes a main shaft 31 that is sealed and installed between the side walls of the water tank 1. Three axially aligned guide plates 32 are evenly mounted on the portion of the main shaft 31 located within the water tank 1. A motor 33 is installed on the outer wall of the water tank 1 to drive the rotation of the main shaft 31. The guide plates 32 are fitted with arc-shaped segments. There is only enough space between two guide plates 32 to accommodate one glass insulator. The motor 33 is a variable frequency motor, which can flexibly adjust its speed according to actual production needs, thereby controlling the pushing frequency of the push roller 3 and achieving precise adjustment of the thermal shock intensity of the glass insulator. Simultaneously, a speed reducer is installed between the motor 33 and the main shaft 31 to further precisely control the rotation speed of the main shaft 31, ensuring that the guide plates 32 can push the glass insulator stably and evenly.

[0031] A connecting water pipe is installed between the two ends of the water tank 1. A circulation pump is installed on the connecting water pipe. The circulation pump is a high-efficiency and energy-saving type, which can ensure the water circulation in the water tank 1, so as to make the water temperature evenly distributed and provide a stable thermal shock environment for the glass insulator. At the same time, multiple temperature sensors are installed in the water tank 1 to monitor the water temperature changes in real time and feed the data back to the control system. The control system automatically adjusts the flow rate of the circulation pump and the power of the heating or cooling equipment according to the preset temperature range to ensure that the water temperature is always maintained within a suitable range.

[0032] The four-section round rod 21 is made of smooth stainless steel, which boasts excellent hardness, wear resistance, and corrosion resistance, along with a high degree of surface smoothness. The rod undergoes fine polishing to reduce the coefficient of friction when in contact with tempered glass, minimizing scratches and wear. A Teflon coating can also be applied to the stainless steel surface. Teflon has an extremely low coefficient of friction, a smooth surface, and strong chemical stability, significantly reducing friction between the tempered glass and the rod, thus lowering the risk of wear. Furthermore, the Teflon coating is corrosion-resistant and high-temperature resistant, making it suitable for various environmental conditions.

[0033] In actual production, the glass insulator slides into the upper end of the slide 2 and down the four-section round rod 21 to the middle of the water tank 1. During this process, the glass insulator undergoes a rapid cooling process by hot water, experiencing thermal shock. At this time, the push roller 3 rotates under the drive of the motor 33, and the push plate 32 pushes the glass insulators sequentially to the output conveyor. This design greatly improves the thermal shock resistance and production efficiency of the glass insulators, while ensuring the stability of product quality.
