Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

referring to fig. 1-6, the utility model provides a double-deck waterproof ammeter case for mining machinery plant, including box 1, box 1 includes integrative top cap 11, outer housing 12 and inner housing 13 that set up, and outer housing 12 and inner housing 13 are all located the lower extreme of top cap 11, and inner housing 13 is located outer housing 12, and so design, guaranteed that top cap 11 upper surface does not have the connecting gap, and the rainwater can not get into box 1 easily, forms hollow air cavity 14 between inner housing 13 and the outer housing 12; a bottom plate 15 is fixedly installed on the lower surface of the inner cover shell 13, a plurality of air inlet holes 17 are formed in the bottom plate 15, outside air enters the inner cover shell 13 through the air inlet holes 17, then heat generated by the work of the ammeter 5 is taken away and discharged from the air outlet holes 18 to enter the hollow air cavity 14, and finally the outside air flows downwards along the hollow air cavity 14 and is discharged out of the box body 1; the inner wall of the inner cover shell 13 is provided with an ammeter 5 and a plurality of air outlet holes 18; the front surfaces of the inner housing 13 and the outer housing 12 are both provided with door opening through grooves 16, the lower ends of the door opening through grooves 16 are flush with the lower surfaces of the inner housing 13 and the outer housing 12, so that the box door 2 can be inserted into the door opening through grooves 16 from bottom to top, in order to prevent rainwater from entering the box body 1 from the joint of the door opening through grooves 16 and the box door 2, the box door 2 is designed to be inserted into the door opening through grooves 16 from bottom to top, so that the width of the box door 2 is certainly larger than that of the door opening through grooves 16, rainwater is effectively prevented from entering the box body 1 from the joint of the door opening through grooves 16 and the box door 2, in addition, the box door 2 is designed on the front surface of the box body 1, and the box door 2 is inserted into the door opening through grooves 16 from bottom to top, the upper end of the box body 1 is ensured to be complete without connecting gaps, so that the rainwater cannot easily enter the box body 1, the length of chamber door 2 is greater than the length that the logical groove 16 of door opening, the design like this, ensure that the lower extreme of chamber door 2 can not shift up to the top of bottom plate 15, further prevent that external rainwater from getting into in the box 1 from the junction of bottom plate 15 and the logical groove 16 of door opening, if 2 length of chamber door is less than the length of the logical groove 16 of door opening, so insert back in spacing draw-in groove 19 when 2 upper ends of chamber door, the lower extreme of chamber door 2 must be located the top of bottom plate 15, at this moment, form the opening between the lower extreme of bottom plate 15 and chamber door 2, external rainwater can directly get into in the box 1 through this opening, be provided with spacing draw-in groove 19 with 2 grafting sealing connection.

As an alternative embodiment, a sliding strip 21 fixedly connected with the box door 2 is slidably and hermetically installed in the hollow air cavity 14, and the sliding strip 21 is provided to further seal the joint of the box door 2 and the door opening through groove 16, so as to prevent rainwater from entering the box body 1 through the joint of the box door 2 and the door opening through groove 16.

the inner wall of the hollow air cavity 14 is provided with a plurality of vertical sealing clamping grooves 23, sealing clamping strips 22 are arranged in the sealing clamping grooves 23 in a sliding sealing mode, and the sealing clamping strips 22 are fixedly connected with the sliding strips 21.

the air inlet 17 is an inclined hole, and the central axis of the air inlet 17 is not perpendicular to the lower surface of the bottom plate 15, so that the design is convenient for outside air to enter the inner cover shell 13.

Articulated on chamber door 2 have a string detain 3, install on the box 1 and hang the post 4 of hanging that detain 3 articulate the connection with hanging, design like this, prevent that chamber door 2 from influencing 5 holistic leakproofness of case of ammeter in the logical groove 16 of door opening from automatic gliding.

When the double-layer waterproof electric meter box for the mining machinery plant is used, the box door 2 is inserted into the through groove 16 of the door opening from bottom to top until the upper end of the box door 2 is inserted into the limiting clamping groove 19, so that rainwater is difficult to enter the box of the electric meter 5, no opening gap is arranged on the top cover 11, the opportunity for rainwater to enter the box of the electric meter 5 is avoided, even if the rainwater enters the box body 1 from the joint of the box door 2 and the through groove 16 of the door opening, the rainwater flows downwards along the inner wall of the inner cover 13 under the action of self gravity and finally flows out from the air inlet 17, the work of the electric meter 5 is not influenced at all because the electric meter 5 is arranged on the inner wall of the inner cover 13 far away from the box door 2, the rainwater cannot enter the inner cover 13 and then flow onto the electric meter 5, and because the gap at the joint of the box door 2 and the through groove 16 of the door opening is small, the, and there is case lid and box 1's joint gap on the up end of 5 casees of traditional ammeter, in case sealed not tight, the rainwater gets into 5 incasement of ammeter very easily, the utility model discloses a set up chamber door 2 in box 1's front, the no joint gap of 1 upper surface of box, therefore waterproof performance is better than 5 casees of traditional double-deck ammeter, and also difficult problem, long service life that take place the rainwater after long-time the use in getting into box 1.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
