Description

Technical Field

[0002] The electric control box contains one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, and is completely assembled together by the manufacturer using structural components. Silicone rubber is used to seal the various components of the electric control box. Silicone rubber refers to a rubber with a main chain composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups. Ordinary silicone rubber is mainly composed of silicon-oxygen chain links containing methyl and a small amount of vinyl.

[0003] If impurities are mixed into silicone rubber seals during production, it may cause bulges or depressions on the surface of the silicone rubber seals, which may reduce its sealing performance and cause leakage after installation. In order to ensure the sealing effect during the production of silicone rubber sealing rings, the silicone rubber needs to have sufficient elasticity, be able to be stretched and compressed, and generate appropriate rebound force to fill the sealing gap, otherwise poor sealing may occur and cause leakage. Due to the particularity of the working environment of ships, silicone rubber seals need to have a certain degree of corrosion resistance. When exposed to harsh conditions such as seawater and salt spray for a long time, whether the seals will be corroded and lose their sealing function, so the silicone rubber seals need to be inspected before they are taken.

The two lifting screws 8 are both threaded through the return plate 3. A cavity 56 is provided in the simulation box 1. The lower ends of the two lifting screws 8 rotate through the vertical plate 2 and the simulation box 1 and extend into the cavity 56. The two lifting screws 8 are connected by a first transmission mechanism 9. Specifically, the first transmission mechanism 9 includes two first pulleys 10. The two first pulleys 10 are coaxially connected to the two lifting screws 8 respectively, and the two first pulleys 10 are connected by a synchronous belt transmission.

After the simulation is completed, the stretching mechanism 6 is used to detect whether its sealing is qualified, and the detection of the silicone rubber sealing is more comprehensive.

[0039] In order to test the elasticity of the silicone rubber seal, a stretching mechanism 6 is set up. The stretching mechanism 6 includes two L-shaped plates 12.

When the value of the tension sensor is zero, the distance between the two fixed plates 5 is compared with the initial distance to detect the elasticity of the silicone rubber seal. If the elasticity is insufficient and the rebound force is insufficient, insufficient sealing may easily occur.

Both ends of the roller 23 are equipped with fixed The fixed gear 32 and the fixed gear 32 match the card plate 31, and the slide plate 22 is threadedly connected with a movable screw 54. It should be noted that the external threads of the two movable screws 54 have opposite rotation directions, and the movable screw 54 is rotated away from the end of the slide plate 22 and penetrates the side plate 20. The fixed plate 5 rotates and penetrates a transmission shaft 24. The transmission shaft 24 and the two movable screws 54 are connected through a third transmission mechanism 25. Furthermore, the third transmission mechanism 25 includes a fourth pulley 26 and a fifth pulley 27.

At this time, the power shaft 36 is driven to rotate by the driving motor 37, and the power shaft 36 drives the two rollers 23 to rotate relative to each other, so that the silicone rubber seal can be pushed, thereby adjusting its position.

[0044] In order to detect the surface of the silicone rubber seal, a detection mechanism 42 is set up.

A power motor 51 is installed outside the U-shaped plate 44, and the drive shaft of the power motor 51 is coaxially installed with a main transmission wheel 50, which is meshed and connected with the slave transmission wheel 49.

[0045] Through the above technical features: the power motor 51 drives the connecting shaft 48 to rotate, the connecting shaft 48 drives the arc plate 55 to rotate through the driving gear 47, and the arc plate 55 drives the camera 43 to rotate, so that various parts of the silicone rubber seal can be inspected through the camera 43 to achieve a comprehensive inspection.

The fixed plate 5 drives the silicone rubber seal to stretch through the side plate 20. After stretching for a certain distance and time, the silicone rubber seal is relaxed. When the value of the tension sensor is zero, the distance between the two fixed plates 5 is compared with the initial distance to test the elasticity of the silicone rubber seal.

When repositioning the silicone rubber seal, push the return-shaped fixing plate 30 so that the card plate 31 is not limited to the fixed gear 32. At this time, the power shaft 36 is driven to rotate by the driving motor 37, and the power shaft 36 drives the two roller shafts 23 to rotate relative to each other, so that the silicone rubber seal can be pushed, thereby adjusting its position;
