Description

Technical Field

[0001] The utility model relates to the technical field of intrinsically safe products for mines, and particularly relates to a waterproof outer shell connection and fixing structure. Background Technique

[0002] The connection and fixing structures include welding method, bolt connection method, steel groove method and glass glue bonding method. The temporary fixing methods include scaffolding method, steel pipe method and hoisting method. The mixed fixing methods include welding + bolt connection method and steel groove + glass glue bonding method. The non-detachable fixed connections include welding, riveting and gluing, etc.

[0003] The prior art patent document with the publication number CN216625458U discloses a new type of waterproof motor housing, which includes a main housing. A junction box is provided above the main housing. A wiring hole is opened on the front surface of the junction box, and a wiring inner box is provided inside the junction box. A through hole is opened at a position corresponding to the wiring hole on the front surface of the wiring inner box. The through hole and the wiring hole are connected by a wiring pipe. A wiring terminal and a wiring hole are provided at the lower end inside the wiring inner box. A drain pipe is provided on the rear surface of the junction box, and a water outlet is opened at a position corresponding to the drain pipe at the bottom of the rear surface of the junction box. A top cover is installed on the top of the junction box. The main housing and the junction box are of an integral structure. The junction box, the wiring inner box and the wiring pipe are of an integral structure. The height of the wiring inner box is greater than the height of the junction box. The top cover and the junction box are fixedly connected by bolts, and bolt holes are opened on the top cover. There are four bolt holes in total, and the four bolt holes are respectively opened at the four corner positions of the top cover. Bolt fixing holes are opened at positions corresponding to the bolt holes on the upper surface of the junction box. The structure of this waterproof motor housing is scientific and reasonable, safe and convenient to use. The junction box and the main housing are of an integral structure, reducing the number of seals used and fundamentally reducing the water inlet positions. The junction box is of a double-layer structure inside and outside, and the inner box is higher than the outer box, greatly reducing the possibility of water entering the inner box. At the same time, a water outlet and a drain pipe are provided at the corresponding position of the sandwich between the wiring inner box and the junction box, and the accidentally entered water will also be discharged from the drain pipe out of the junction box and will not enter the wiring inner box, thus preventing accidents such as open circuit and burnout caused by water entering the motor interior, with high use safety and effectively extending the service life of the motor.

[0004] However, in the prior art patent CN216625458U, due to the relatively complex fixing of the housing of the new type of waterproof motor housing and the need to manufacture flange plates, the cost is high, there are many fixing bolts, it is inconvenient to operate, the efficiency is low, and the quality of the welding is uneven, which affects the fixing effect of the new type of waterproof motor housing.
