Description
Technical field
The present invention relates to a kind of electrical system casing ventilation hole and use protector, relate in particular to the protector of electrical system casings such as convergence control cabinet, distribution box, mechanism case with the ventilating opening place.
Background technology
The electrical system casing in use; As do not have the forced ventilation requirement, generally adopt ventilation hole to dispel the heat, take a breath, but after offering ventilation hole; Dust and little winged insect can get into box house from ventilation hole; Also have rainwater when rainy and get into box house, bring potential safety hazard so for the reliability service of the equipment in the casing from ventilation hole, so the ventilation hole protection object of attaching most importance to; The degree of protection of the above-mentioned casing of national Specification need reach IP54, so the degree of protection of ventilation hole protector also need reach the national standard of IP54.
Industry is to set up Air Filter for dustproof usual way at present; Usually the method that adopts for waterproof is to set up bucker; The Chinese patent notification number is CN201726049U; The day for announcing is on 01 26th, 2011; Name is called and discloses a kind of outdoor case in ' a kind of outdoor case use the ventilation hole protector ' specification and use the ventilation hole protector, comprises the protector housing that is used to be installed on the outdoor case and is positioned at the dustproof filter pad of protector enclosure interior, and this protector housing comprises bridging board, be positioned at the bridging board both sides and through continuous biside plate of bridging board and the side plate that is positioned at the bridging board rear end and links to each other with bridging board; The inboard of said bridging board, biside plate and side plate is configured for holding the cavity of dustproof filter pad, and said dustproof filter pad is spacing by the Stop structure of being located at the bridging board front end.But this ventilation hole protector can not reach the national standard of IP54, and Air Filter all is arranged on the bucker in this protector, and this structure is insecure, and ventilation effect is bad.Bucker normally is fixed on the casing with marine glue or water-proof sealing strip in addition; Because bucker is located at the casing outside; So marine glue or waterproof sealing adhesive tape are directly exposed to occurring in nature, ageing failure or be considered to destroy very easily, and then bucker and casing are damaged.
Summary of the invention
The object of the present invention is to provide a kind of electrical system casing ventilation hole to use protector, not enough with the degree of protection that solves ventilation hole protector in the prior art, mount is insecure, the problem that ventilation effect is bad.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of electrical system casing ventilation hole is used protector, comprises shell, the biside plate that said shell comprises bridging board, is positioned at the bridging board both sides and links to each other through bridging board; Reach end plate with biside plate and bridging board back-end closure; Shell front end spiral-lock has shell block, and said shell block is provided with and is used for the intercommunicating pore that is communicated with ventilation hole, and the cavity between intercommunicating pore and shell and the shell block has constituted downward vent passages jointly; Shell block is provided with the Air Filter that is used for the intercommunicating pore sealing; The bridging board of shell and biside plate protrude respectively on inner wall separately and are provided with at least one assembling that is used to assemble convexity, are provided with tapped blind hole on the assembling convexity, and the corresponding said assembling raised position of shell block is provided with the assembling through hole.
Vent passages below between shell and the shell block is provided with water-retaining structure.
Described water-retaining structure comprises the staggered outstanding water fender of establishing; A two adjacent water fenders end face separately is installed in respectively on the sidewall of each self-corresponding shell; The overhang center of shell of the other end, the both sides of water fender extend to respectively on the medial surface of end plate of shell block rear end face and shell.
Said water fender free end is in the horizontal alignment angle that has a down dip.
Convex with in the below of water fender on the said shell block rear end face and be used for the support raised line that cooperates with the water fender side lap, the medial surface of the opposite side of water fender and the end plate of shell fixedly installs.
Said shell block front end face convexes with the preceding ring platform that is used to be inserted in the casing ventilation hole in the intercommunicating pore place; The endoporus front end of preceding ring platform is provided with Turbogrid plates; The shell block rear end face convexes with the back ring platform of internal diameter and intercommunicating pore equal diameters in the intercommunicating pore place; Said back ring platform inner chamber and intercommunicating pore have constituted the cavity that holds Air Filter jointly, and Air Filter is arranged in the said cavity.
The shell block front end face is provided with seal groove in the air grid peripheral ring, is provided with the waterproof grommet that is used for the cabinet exterior sealing in the seal groove.
Said bridging board is semicircle.
The outer edge surface of the front end edge shell of shell convexes with eaves, and shell block has and is used for and the spacing outer edge surface that cooperates of the inner edge surface of said eaves, and the shell block buckle is in the eaves of shell.
A kind of electrical system casing ventilation hole of the present invention is used protector, is provided with shell block between shell and the cabinet exterior, makes fixed structure more firm; The protruding protrusion of assembling is arranged on the inner wall of bridging board and biside plate; Assemble more firmly, simultaneously the draught area of protector increases, and reaches good ventilation effect; Air Filter is installed on the shell block, makes fixing more firm of Air Filter.
Further, the outstanding interlaced water fender of establishing of outer casing underpart under the situation that does not increase the distance between shell lower ending opening and the ventilation hole, has prevented that effectively rainwater is splashed in the casing by vent passages.
Further, the downward-sloping angle of water fender free end, when effectively having prevented to dabble, aqueous reflux advances vent passages.
Further, the shell block front end face is provided with the air grid of protrusion, and air grid cooperates with the ventilation hole sleeve, better with the protector location and installation in the casing vent, simultaneously air grid also with the Air Filter accurate localization in intercommunicating pore.
Further; The waterproof grommet of shell block front end face setting does not need around shell, to be coated with in the prior art fluid sealant and prevents that rainwater is from connecting the casing of entering between the slit; Seal is arranged on shell block inside, is difficult for wearing out, and has prolonged the useful life of ventilation hole protector.
Further, semicircular bridging board has prevented shell top ponding.
