Abstract
The utility model discloses a burning speed detection device, which comprises a photosensitive seat (1). A front photosensitive hole (1a) and a rear photosensitive hole (1b) are arranged on the photosensitive seat (1), a front photosensitive tube (2) is installed in the front photosensitive hole (1a), and a rear photosensitive tube (3) is installed in the rear photosensitive hole (1b). The front photosensitive tube (2) and the rear photosensitive tube (3) are vertically toward the upper end orifices of the photosensitive holes, and the upper end surface of the photosensitive seat (1) is fixedly provided with a horizontal transparent plate (4). The burning speed detection device has the beneficial effects for replacing manual defection, avoiding influence of artificial factors, increasing the detecting precision, and saving leading wires and gunpowder.
Description
Technical field
The utility model belongs to a kind of checkout equipment, relates in particular to a kind of pick-up unit of combustible substance burning rate.
Background technology
The detection of substance combustion speed is very crucial, and as gunpowder medicinal powder, the burning rate of fireworks leads detects, and detects data by these, can determine rational blasting time according to the explosion field condition, determines the firework display time of safety.
But existing detection technique almost is manually to finish entirely, the tester is implemented in a flat field ground and lays a lead-in wire, or arrange one section gunpowder, in the time of some combustion wire or gunpowder, by manually pressing stopwatch, get simultaneously at lead-in wire or gunpowder after-flame, again by manually pressing stopwatch, conversion by time and length draws burning rate.
The shortcoming of prior art is: detection is influenced by human factor, and it is big to detect error, and the lead-in wire and the gunpowder of waste are all very many.
The utility model content
The purpose of this utility model provides a kind of burning rate pick-up unit, can replace manual detection, avoids artificial factor, improves accuracy of detection, saves lead-in wire and gunpowder.
For achieving the above object, the utility model is explained a kind of burning rate pick-up unit, its key is: comprise the sensitization seat, photographic hole and back photographic hole before having on this sensitization seat, in the photographic hole preceding sensitizing tube is installed before described, the back sensitizing tube is installed in the back photographic hole, and described preceding sensitizing tube and back sensitizing tube all are vertical towards the aperture, upper end of photographic hole, and the upper surface of described sensitization seat is fixed with the horizontal light transmission plate.
The bottom of described sensitization seat is equipped with tube at the bottom of the shading, and described have power lead and signal wire tube at the bottom of this shading of preceding sensitizing tube and back sensitizing tube to stretch out.
Combustible is laid on the horizontal light transmission plate, after combustible is lighted, its flare point is successively by preceding photographic hole and back photographic hole, preceding sensitizing tube in the photographic hole and back sensitizing tube are successively experienced the light that flare point is sent, and send to computer system, computer system in conjunction with the distance of the two, just can be calculated burning rate according to the mistiming of the two fast.
The horizontal light transmission plate mainly plays the effect of heat insulation printing opacity.Can adopt the light transmissive material of a lot of fire-retardant thermal resistances to make.
Described horizontal light transmission plate is a glass plate.
Remarkable result of the present utility model is: a kind of burning rate pick-up unit is provided, has replaced manual detection, avoided artificial factor, improved accuracy of detection, saved lead-in wire and gunpowder.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of burning rate pick-up unit, comprise sensitization seat 1, photographic hole 1a and back photographic hole 1b before having on this sensitization seat 1, sensitizing tube 2 before being equipped with in the photographic hole 1a before described, back sensitizing tube 3 is installed in the back photographic hole 1b, and described preceding sensitizing tube 2 and back sensitizing tube 3 all are vertical towards the aperture, upper end of photographic hole, and the upper surface of described sensitization seat 1 is fixed with horizontal light transmission plate 4.
The bottom of described sensitization seat 1 is equipped with tube 5 at the bottom of the shading, and described have power lead and signal wire tube 5 at the bottom of this shading of preceding sensitizing tube 2 and back sensitizing tube 3 to stretch out.
Sensitizing tube can adopt photodiode.
Combustible is laid on the horizontal light transmission plate 4, after combustible is lighted, its flare point is successively by preceding photographic hole 1a and back photographic hole 1b, preceding sensitizing tube 2 in the photographic hole and back sensitizing tube 3 are successively experienced the light that flare point is sent, and send to computer system, computer system in conjunction with the distance of the two, just can be calculated burning rate according to the mistiming of the two fast.
Horizontal light transmission plate 4 mainly plays the effect of heat insulation printing opacity.Can adopt the light transmissive material of a lot of fire-retardant thermal resistances to make.
Described horizontal light transmission plate 4 is a glass plate.
Although above structure is described preferred embodiment of the present utility model in conjunction with the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression; as the distance of photographic hole 1a and back photographic hole 1b before changing; material of change horizontal light transmission plate 4 or the like, such conversion all falls within the protection domain of the present utility model.
