Description

Waterproof power storage function PLC switch board

Technical Field

The utility model relates to a waterproof accumulate function PLC switch board.

Background

It is used for installing semiconductor refrigeration dehumidifier usually to waterproof accumulate function PLC switch board among the prior art, has seted up the air intake on the cabinet body usually, and air intake department also can be provided with the fan cover at present, but it is usually only in order to block external dust and debris entering cabinet internally, can't play good water-proof effects, and external steam still can get into the cabinet along with the air inlet internal, and water-proof effects is relatively poor from this.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a waterproof accumulate function PLC switch board, can block that steam gets into in the box, play good water-proof effects.

In order to realize the technical effects, the utility model adopts the technical scheme that: the utility model provides a waterproof accumulate function PLC switch board, includes the switch board body, offers in air intake on the switch board body, air intake department is provided with the filtration ventilation screen panel, the filtration ventilation screen panel includes transversal outer housing and the inner housing of personally submitting L shape, the outer housing with the upper portion looks fixed connection of air intake, the inner housing with the lower part looks fixed connection of air intake, the outer housing with form the ventilation chamber between the inner housing, the inside wall in ventilation chamber is fixed and is provided with a plurality of baffles, the transverse dimension of baffle is less than the transverse dimension in ventilation chamber, the opening in ventilation chamber is located the below of filtration ventilation screen panel.

In a further improvement, the baffle is vertically and fixedly arranged on the inner side wall of the ventilation cavity.

The further improvement is that the baffle comprises a first baffle fixedly connected with the outer cover shell and a second baffle fixedly connected with the inner cover shell, and the first baffle and the second baffle are arranged in a staggered manner.

The further improvement is that the first baffle plate and the outer housing are welded and fixed or integrally formed, and the second baffle plate and the inner housing are welded and fixed or integrally formed.

In a further improvement, the outer cover shell and the inner cover shell are welded and fixed with the control cabinet body.

In a further improvement, the filtering and ventilating net cover is rectangular.

In a further improvement, the width of the opening of the ventilation cavity is half of the width of the filtering ventilation net cover.

The utility model has the advantages and the beneficial effects that: the air inlet department at the cabinet body has set up the filtration ventilation screen panel of labyrinth type, and external steam forms the comdenstion water by the entry of ventilation screen panel by supreme entering down after the encounter is cold, and it can not get into this internal along the lateral wall outflow of ventilation screen panel to be blockked the back by the baffle of ventilation intracavity, plays good water-proof effects from this.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-5, a waterproof electricity storage function PLC switch board, include switch board body 1, set up in air intake on the switch board body 1, air intake department is provided with filtration ventilation screen panel 2, filtration ventilation screen panel 2 includes transversal outer housing 3 and the inner housing 4 of personally submitting L shape, outer housing 3 with the upper portion looks fixed connection of air intake, inner housing 4 with the lower part looks fixed connection of air intake, outer housing 3 with form the draft chamber between the inner housing 4, the inside wall in draft chamber is fixed and is provided with a plurality of baffles 5, the transverse dimension of baffle 5 is less than the transverse dimension in draft chamber, the opening in draft chamber is located the below of filtration ventilation screen panel 2.

Preferably in this embodiment, the baffle 5 is vertically fixed to be arranged on the inner side wall of the ventilation cavity, and the baffle 5 is vertically arranged in the ventilation cavity, so that condensed water can be better prevented from entering the cabinet body, and ventilation is facilitated.

In order to further improve the water blocking effect, the baffle 5 comprises a first baffle 5 fixedly connected with the outer housing 3 and a second baffle 5 fixedly connected with the inner housing 4, and the first baffle 5 and the second baffle 5 are arranged in a staggered manner.

In this embodiment, the first baffle 5 is welded to the outer casing 3, most of the second baffle 5 is welded to the inner casing 4, and the second baffle 5 at the end of the inner casing 4 may be integrally formed with the inner casing 4.

In order to facilitate processing and manufacturing, the outer casing 3 and the inner casing 4 are welded and fixed with the control cabinet body 1.

In order to match with the control cabinet body 1 and ensure compact overall structure, the filtering and ventilating net cover 2 is rectangular.

In order to guarantee that the efficiency of air inlet improves the effect of blocking water simultaneously, the open-ended width in ventilation chamber be with filter ventilation screen panel 2 width half, the opening undersize in ventilation chamber influences ventilation efficiency, if the opening in ventilation chamber is too big, the baffle 5 in ventilation intracavity blocks water the effect relatively poor, selects its width from this to be whole filter ventilation screen panel 2 width half as the optimal choice.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
