Abstract
The utility model discloses a dew-condensing and water-collecting plate having hidden vent holes. The cross section of the water-collecting plate is in a wave-shaped fluctuant structure, wherein each wave trough position is provided with a water guide groove; a plurality of vent holes are arranged above the side walls of each water guide groove; the upper part of at least one side wall of each water guide groove is provided with a bulge at one side of the water guide groove; and the vent holes are arranged below the bulge position of the side wall. The vent holes are arranged in the water-collecting plate and positioned below the bulge position of the side wall, has a large diameter and good air permeability, and can not be easily blocked by dust. Thus, the water-collecting plate is applicable to the damp environment, and can prolong the service life of electrical equipment and improve the operational safety and reliability of the electrical equipment.
Description
Technical field
The utility model relates to a kind of protection baffle plate that is used for preventing in the outdoor electric component box condensation water droplet, specifically a kind of condensation water collection sheet with hidden air vent hole.
Background technology
The mechanism case of outdoor converting equipment and terminal box are installed in the metal enclosed casing; Produce condensate owing to be everlasting when influenced by ambient air temperature and wetness in the casing; Condensing water droplet causes metal parts corrosion and aqueous corrosion in mechanism part and causes that the mechanical part wear extent is big and malfunctioning; Particularly drop on the low-voltage controling appliance and cause misoperation or short trouble; Cause insulating element insulation decline simultaneously and whole equipment can't normally be moved, use to equipment to bring about great losses, particularly cause power equipment malfunction or tripping to cause more serious accident.In order to prevent this from occurring, the bottom in the electric equipment case installs the dehumidifying heater additional usually, prevents that through heating humid air from condensing at the top.Yet; Humid air is heated and rises and most of humid air is discharged by casing side steam vent; But still some moist air stream concentrates at the top of casing, and former thereby make moisture condensation knot water because of the top material temperature difference, water droplet drops on parts or the insulating element; Still can cause parts corrosion or aqueous corrosion, and the problem of electric terminal short circuit or decreasing insulating.
In order to address this problem; TOHKEMY 2005-228780A discloses a kind of anti-condensation electric component box; At the top flat board that is obliquely installed is housed, has the radius that is used to ventilate air vent hole on the flat board, make the steam of below reach the casing top through air vent hole at 2.5-3.5mm; The water droplet that the while top falls can not be fallen by air vent hole, thereby protection is fixed on the electric equipment of dull and stereotyped below.Its shortcoming is that the air vent hole aperture on the flat board is less; The water droplet that falls when the top is prone to above air vent hole, form moisture film during by dull and stereotyped upper surface landing; With the closed vent hole, cause its venting capability to descend, cause steam to drop onto on the electric equipment condensing below the flat board.To this problem; The applicant also once proposed solution in CN10193461A; A water collection sheet that has many handles road water guide groove promptly is set below the casing top; Top between adjacent water guide groove has air vent hole, and the water drops flows down that the top falls is drained by water guide groove one or both ends in the water guide groove again.Though the water droplet of top drippage can not flow through air vent hole; But the aperture of air vent hole can not be excessive; Otherwise water droplet can be dropped on the electric equipment of below by the air vent hole place, and the aperture is too small, and permeability is bad first; When air was moist, part steam may condense in the water collection sheet lower end and directly be dropped on the electric equipment; The dust sealing of second being landed easily needs often cleaning dust stratification, otherwise can lose permeability.
Summary of the invention
The purpose of the utility model is to the problems referred to above; A kind of condensation water collection sheet with hidden air vent hole is provided; Can effectively prevent on the electric equipment in following of top condensate to the container, prolong electric equipment life-span and the safety and reliability that improve the electric equipment operation.
The technical scheme that the utility model solves the problems of the technologies described above is: said water collection sheet cross section undulate relief fabric; The trough present position is the water guide groove; Water guide recess sidewall top has a plurality of air vent holes; It is characterized in that: said every water guide groove has at least a side wall upper part to be provided with the convexity of water guide groove one side, and said air vent hole is opened in the below at this projected side wall position.
Water collection sheet is installed in below, casing top; The humid air that rises can get into the casing upper space along the air vent hole on the water collection sheet; And casing top condensation water falls into the water guide groove after being dropped on the water collection sheet; Be guided to casing one side by the water guide groove, flow to bottom half again and discharge or receive once more thermal evaporation.Because air vent hole is built in the below at projected side wall position; Thereby top condensation water droplet can not drop in the air vent hole; Therefore, the aperture of air vent hole is unrestricted, and large-size can be set; To make things convenient for humid air to rise to the top through water collection sheet apace, can also prevent that air vent hole from stopping up because of laying dust.
Processing for ease, the water guide recess sidewall of offering air vent hole is inclined to set, and makes the projection of this side wall upper part on vertical guide drop in the water guide groove.
The utility model water collection sheet air vent hole is built in the below at projected side wall position, and the aperture of air vent hole is increased, and not only permeability is good; And air vent hole is difficult for being stopped up by dust; Can adapt to and use, can effectively collect the water droplet that the top falls, thereby avoid being dropped on the electric equipment than wet environment; Can prolong electric equipment useful life, improve the safety and reliability of electric equipment operation.In addition, water collection sheet can adopt plastics or composite fibre materials to process, and processes and install very convenient.

Embodiment
As depicted in figs. 1 and 2; Water collection sheet cross section undulate relief fabric; The trough present position is a water guide groove 1; Two sidewalls 2,3 of each water guide groove 1 are inclined to set, and one of them sidewall 2 upper end is formed slopely convexity 21 to water guide groove 1 direction, makes this sidewall 2 tops projection on vertical guide drop in the water guide groove 1.The below of this projected side wall 21 offers several strip air vent holes 4, and the length of each air vent hole 4 and widely can surpass 10mm is to improve its permeability.
Water collection sheet is installed in below, casing top; The humid air that rises can get into the casing upper space along the air vent hole on the water collection sheet; And casing top condensation water falls into the water guide groove after being dropped on the water collection sheet; Be guided to casing one side by the water guide groove, flow to bottom half again and discharge or receive once more thermal evaporation.Because air vent hole is built in the below at projected side wall position; Thereby top condensation water droplet can not drop in the air vent hole; Therefore, the aperture of air vent hole is unrestricted, and large-size can be set; To make things convenient for humid air to rise to the top through water collection sheet apace, can also prevent that air vent hole from stopping up because of laying dust.
Water collection sheet can adopt plastics or composite fibre materials to process, and receives variations in temperature littler than metal, is difficult for making moisture condensation knot water, can adopt gluing connection, and processing and installation are all very convenient, and can cut into polylith splicing assembling.
