Description

Technical Field

[0001] This utility model relates to the technical field of chemical electrical structures, specifically a protection device for electrical instrument components in chemical enterprises. Background Technology

[0002] Electrical instruments are a general term for instruments and meters. Commonly used electrical instruments are used to measure electrical parameters, monitor power quality, and control electrical equipment. They are widely used in industries such as industry, agriculture, scientific research, education, military, transportation, medical care, and telecommunications. Due to high safety requirements during transportation, electrical instruments are easily damaged by collisions. Therefore, protective devices are commonly used to protect them.

[0003] An existing electrical instrument protection device, such as one with patent publication number CN221863362U, first inserts the electrical instrument into the protective housing through an opening, allowing the outer wall of the instrument to contact the rubber strip inside the breathable pad. Then, a drive element is activated, causing a rotating rod to rotate. This rotating rod then drives a helical gear, which in turn drives a helical gear, which in turn drives a rotating rod. Finally, the helical gear drives a rotating rod. When the rotating rods rotate synchronously, the shaft fan on the rods also rotates, generating airflow inside the protective housing. This improves air circulation and breathability. When the electrical instrument is subjected to significant impact, the elasticity of the breathable pad and rubber strip cushions the pressure exerted by the protective housing. The device also incorporates a heat dissipation structure and a breathable pad, which not only cushion the pressure but also allow air to circulate within the protective housing, enhancing breathability and achieving cooling and dehumidification effects on the electrical instrument.

[0004] However, when this structure is used in the workshops of chemical enterprises, its protective performance is not sealed, making it susceptible to external corrosion and resulting in poor reliability. Utility Model Content

The middle of the bottom side of the connecting seat 2 is connected to the middle of the top side of the outer ring 6 via the connecting plate 5. The inner ring side of the outer ring 6 is constrained by multiple sets of ball bearings 7 and the inner ring 8. The outer ring side is rotatably connected, and the middle part of the left and right sides of the outer end of the inner thread cover 9 is respectively connected to the inner side of a set of handles 10; the connecting seat 2 is fixed in the corresponding position in the workshop by the fixing plate 3, thereby positioning the electrical instrument unit 1. When the inner thread cover 9 is in the open state outside the outer thread ring 4, it is connected and suspended by the connecting plate 5, which facilitates the operation and use of the electrical instrument unit 1. When the two sets of handles 10 are held to lift the inner thread cover 9, it can be rolled and constrained in the outer ring 6 by multiple sets of balls 7, so that the inner ring 8 rotates relative to the outer ring 6, thereby screwing the inner thread cover 9 closed on the outside of the outer thread ring 4, thereby sealing and protecting the internal electrical instrument unit 1 and reducing its impact from the external environment.

[0025] It also includes an oil nozzle 11, with one side of the outer end of the outer ring 6 connected to the inner side of the oil nozzle 11; oil can be injected into the ball bearings 7 on the inner wall of the outer ring 6 through the oil nozzle 11, which facilitates lubrication and maintenance.

[0026] It also includes an oil filling cap 12, and the outer side of the oil filling nozzle 11 and the inner side of the oil filling cap 12 can be detachably installed; after the oil filling cap 12 is installed on the outside of the oil filling nozzle 11, the inside of the oil filling nozzle 11 can be sealed and protected, improving reliability.

[0027] It also includes a connecting frame 13, a fan motor 14, a fan blade 15, and an air circulation pipe 16.
