Abstract
The utility model discloses a safety battery for a power-off device. The safety battery comprises a main body, wherein the main body comprises a plurality of nickel-hydrogen batteries between which current-limiting resistors are arranged; the nickel-hydrogen batteries are in serial connection through the current-limiting resistors; epoxy resin is uniformly filled in the main body and coats the outer peripheries of the nickel-hydrogen batteries; a positive wire and a negative wire are arranged on the main body, the positive wire is connected with the positive poles of the nickel-hydrogen batteries, and the negative wire is connected with the negative poles of the nickel-hydrogen batteries. As the nickel-hydrogen batteries are serially connected through the current-limiting resistors, the current intensity is reduced and the probability of electric sparks is low; the epoxy resin is filled outside the battery, so that a heat-insulating role can be played during short circuit, and the safety performance is improved accordingly.
Description
Technical field
The utility model relates to a kind of battery, particularly a kind of cutoff instrument safety battery.
Background technology
At present, mining cutoff instrument is due to the particularity of its use, and in order to guarantee the safety in production under mine, the security performance that its various piece is formed has very high requirement.At present, the mining cutoff instrument that most enterprises is used is used common Ni-MH battery mostly, and its explosion-proof performance and insulation property poor effect, easily have potential safety hazard to the production operation under mine.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cutoff instrument safety battery for above drawback, uses current-limiting resistance to be connected in series a plurality of Ni-MH batteries, reduces size of current, is difficult for producing electric spark; Battery is filled with epoxy resin outward, plays the heat insulation effect of insulation when short circuit, improves security performance.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A cutoff instrument safety battery, comprises body, and wherein, described body comprises a plurality of Ni-MH batteries, between described Ni-MH battery, is provided with current-limiting resistance, and described Ni-MH battery is and is connected in series by current-limiting resistance; Described in body uniform filling have epoxy resin, described epoxy resin is coated on the outside surrounding of Ni-MH battery; Described body is provided with positive electrical wire and negative electrical wire, and described positive electrical wire is connected with Ni-MH battery anode, and described negative electrical wire is connected with Ni-MH battery battery cathode.
During use: positive electrical wire and negative electrical wire are connected on machine.
Beneficial effect: use current-limiting resistance to be connected in series a plurality of Ni-MH batteries, because resistance effect reduces size of current, be difficult for producing electric spark, reach explosion-proof effect, improve security performance; Battery is filled with epoxy resin outward, and at short circuit adstante febre, the coated Ni-MH battery of epoxy resin and current-limiting resistance, play the heat insulation effect of insulation, improves coefficient of safety.
Accompanying drawing explanation
Fig. 1 is the utility model front section view.
Fig. 2 is the utility model side sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment
As shown in the figure, a kind of cutoff instrument safety battery, comprises body 1, and wherein, described body 1 comprises a plurality of Ni-MH batteries 2, and 2 of described Ni-MH batteries are provided with current-limiting resistance 3, and described Ni-MH battery 2 is and is connected in series by current-limiting resistance 3; Described have epoxy resin 4 at the interior uniform filling of body 1, and described epoxy resin 4 is coated on the outside surrounding of Ni-MH battery 2; Described body 1 is provided with positive electrical wire 5 and negative electrical wire 6, and described positive electrical wire is connected with Ni-MH battery battery 5 is anodal, and described negative electrical wire 6 is connected with Ni-MH battery battery cathode.
During use: positive electrical wire and negative electrical wire are connected on machine.
Beneficial effect: use current-limiting resistance to be connected in series a plurality of Ni-MH batteries, because resistance effect reduces size of current, size of current is controlled to 2.5A, form safe current, be difficult for producing electric spark, reach explosion-proof effect, improve security performance; Battery is filled with epoxy resin outward, and at short circuit adstante febre, the coated Ni-MH battery of epoxy resin and current-limiting resistance, play the heat insulation effect of insulation, improves coefficient of safety.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, all should be encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
