Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of power equipment, and specifically relates to a waterproof mechanism box. BACKGROUND

[0002] 72.5-126kV porcelain column type circuit breaker is all outdoor equipment, and the waterproof structure of mechanism box is required higher, and the installation of mechanism box is as shown in the drawing, the top cover of mechanism box is fixed through bolt connection with the base. Figure 1 Because the bolt hole of the top surface of the top cover is all arranged on the plane, the gap of the connecting surface has the hidden danger of water inlet, and after the gap water inlet, the water will flow into the inside of the mechanism box from the bolt hole on the top cover, thereby causing the damp corrosion of the mechanism, the secondary assembly and the secondary part in the inside of the mechanism box, leading to the rust of the element, the aging of the contact point, the failure of the secondary part and the like, seriously affecting the performance of the switch, and the waterproof performance of the mechanism box cannot be guaranteed. UTILITY MODEL CONTENTS

[0003] The utility model provides a waterproof mechanism box in view of the shortage of prior art, realizes the waterproof purpose in structure, guarantees the operation safety of the element, the secondary assembly and the secondary part in the inside of the mechanism box, and improves the quality and product performance of outdoor equipment.

[0004] The utility model discloses a waterproof mechanism box, including the box body and the top cover of solid setting on the box body, the top surface of top cover is equipped with two rows first protruding, and the first through -hole for being bolted with the base is opened on the first protruding, and the second through -hole corresponding with the first through -hole is arranged on the base bottom surface.

[0005] The first through -hole of the top cover is connected with the second through -hole of the base through the bolt, and the height of the first through -hole is lifted by the first protruding on the top surface of the top cover, so that when the connecting gap is water inlet, the water inlet cannot flow into the inside of the mechanism box through the first through -hole due to the block of the protruding.

[0006] As optimization, the aperture of the second through hole is matched with the outer diameter of the first protrusion. When the top cover is connected with the base, the first protrusion can be inserted into the second through hole on the bottom surface of the base, so that the bottom surface of the base is attached to the top surface of the top cover, and the gap between the two end surfaces is reduced, thereby reducing the risk of water entering.

[0007] As optimization, the protrusion height of the first protrusion is not greater than the wall thickness of the base. When the top cover and the base are connected, the first protrusion is inserted into the second through hole, and since the upper end of the first protrusion does not exceed the wall thickness of the base, the bolt is arranged on the first through hole, and the bolt is used to screw and fasten the base and the top cover.

[0008] As optimization, the first protrusion is a stainless steel sleeve, the lower end of the stainless steel sleeve is welded and fixed to the top surface of the top cover, and the inner hole of the stainless steel sleeve penetrates the top cover to form the first through hole. Since the mechanism box is only screwed and fixed to the bottom of the base through the first protrusion, the first protrusion bears the weight of the mechanism box, and the first protrusion adopts the stainless steel sleeve with high strength, thereby improving the connection strength with the base.

[0009] As optimization, the second protrusion is a hollow circular truncated cone structure, the third through hole is arranged on the top surface of the circular truncated cone structure, and the second protrusion is integrally formed with the top cover. The second protrusion is integrally formed, which is convenient to process.

[0010] As optimization, the third protrusion is a circular ring structure, the inner hole of the circular ring structure penetrates the top cover to form the fourth through hole, and the third protrusion is integrally formed with the top cover. The third protrusion is integrally formed, which is convenient to process.

[0011] As optimization, the protrusion height of the first protrusion, the second protrusion and the third protrusion is not less than 5 mm. By limiting the minimum height of the protrusion, the water can not flow into the through hole through the protrusion due to the low height of the protrusion, so that the waterproof effect cannot be achieved.

[0012] As optimization, waterproof glue is applied to the connection gap between the top cover and the base. The connection gap is further sealed by the waterproof glue, and the waterproof effect is further improved.

[0013] The beneficial effects of the utility model are as follows: the first through hole is lifted in height by arranging the first protrusion on the top surface of the top cover, the first through hole of the top cover is connected with the second through hole of the base through a bolt, and when water enters the connection gap, the water cannot flow into the mechanism box through the first through hole due to the blockage of the protrusion. Similarly, the third through hole on the top cover for connecting with the mechanism through a bolt is lifted by the second protrusion, the fourth through hole for passing the output pull rod is lifted by the third protrusion, and water cannot flow into the mechanism box through the third through hole and the third through hole, so that the safe operation of the internal mechanism and secondary elements of the mechanism box is ensured, the waterproof structure is achieved, and the waterproof performance of the mechanism box is greatly improved.
