Abstract

The utility model relates to a blast proof case for special mains connection set, whose safety belongs to the technical field of special purposes. The utility model whose improves the safety and economical benefits when operated in the well is characterized in that the blast proof case for special mains connection set is arranged on a rectangular box body; the switching of the box cover adopts four-connecting-rod structure; the box cover is composed of two steel plates and a clearance gap is arranged on the healing point; the hems of the steel plates are bent upward a plurality of centimeters; the external wall of box is provided with a plastic coverage layer; an angle locating piece is fixedly adopted between the accumulators in the box. The utility model has the function of matching the mains connection set with direct current pulling motive power in the well.

Description

Blast proof case for sepecial mains connection set

Safety-type is applicable to the technical field of special purpose under this utility model.

Prior art feature of the present utility model is the rectangular box made from steel plate, (seeing accompanying drawing 1), case lid two block plates, one side of steel plate is bent downwardly several centimetres and casing hinge-coupled, the another side of steel plate is bent downwardly several centimetres and be separated with the gap and close up (seeing accompanying drawing 3), the hydrogen discharge that produces when making in the casing owing to battery discharging is gone out, chamber interior wall posts vulcanized rubber, be used for anticorrosion, insulation, the fixing plane corrugated sheet of use between battery in the case is swung to prevent the supply unit battery that is in operation.(seeing accompanying drawing 5) (its technological document sees that the explosion-proof shape of JISM6512-1966 is held the electric authority vehicle explanation of pond formula)

The purpose of this utility model is that the raising supply unit is property safe and reliable to operation in the down-hole, and is easy to use, increases economic efficiency.

Feature of the present utility model is, adopt on the basis that has feature now basic, case lid adopts four connecting rod opening-closing structures, each connects with two different connecting rods of length at every case lid and casing both sides, (seeing accompanying drawing 2), two block plates of case lid close up its limit, place at it and are bent upwards several centimetres and be separated with the gap and close up, (seeing accompanying drawing 4), the hydrogen discharge that produces when making battery discharging in the case is gone out, the case inside and outside wall has the plastic mulching layer, (principle of the plastic-blasting method of employing is seen Guangzhou radio-specific equipment 75 years " plastic powder high-pressure static spray technology ").The fixing different keepers of two kinds of triangular shape length that adopt reversal of the natural order of things between storage battery in the case, (seeing accompanying drawing 6) is to prevent in the case storage battery swing that is in operation.

The utility model and prior art feature are relatively, the case lid folding is light laborsaving, because hydrogen is explosion hazard gases in the case, it is particularly important at the down-hole security of operation to guaranteeing supply unit to remove the interior hydrogen of case, because hydrogen lta, so note removing dead angle in the case during design, this structure of case lid compares with existing structure, hydrogen drops to 0.06% through actual measurement by 0.3% in test, thereby has improved down-hole property safe and reliable to operation.

Fixingly between storage battery in this device case adopt reversal of the natural order of things keeper and existing corrugated sheet dividing plate relatively, surplus every locomotive can save 600 on the benefit yuan, and effect is than now good.

The utility model than domestic " safety-type ' supply unit relatively; (seeing safety electric source apparatus specification); greatly improved the useful life of storage battery and supply unit case; the life of storage battery will rise to 18-24 month by 3-6 month; the life-span will be by rising to 3-5 half a year at the bottom of the supply unit case; annually calculate with 1000 locomotives, 2000 casees supply unit meters can be country and save more than 50,000,000 yuan every year.

Claims

1. one kind connects the flameproof special type supply unit case of forming by what steel plate was made by case lid and casing, it is characterized in that case lid adopts four connecting rod opening-closing structures, two block plates of case lid close up its limit, place at it and are bent upwards, and adopt the angle keeper between storage battery in the device case.

2. by the described supply unit case of claim 1, it is characterized in that each connecting rod with two varying lengths of every case lid and casing both sides is connected.

3. by the described supply unit case of claim 1, it is characterized in that inside and outside the chest plastic mulching layer being arranged.

4. by the described supply unit case of claim 1, it is characterized in that fixing between storage battery in the case and adopt two kinds of keepers that angular shape length is different.
