Abstract
The utility model discloses a zigzag type bulletproof ventilation net which comprises protective plate clamping grooves and primary protective plates, wherein the primary protective plates are obliquely arranged in the protective plate clamping grooves in a shutter type. At least one layer of secondary protective plates is further arranged in the protective plate clamping grooves. The secondary protective plates are arranged at the back of the primary protective plates side by side, and the front protective plates and the back protective plates are connected side by side on the end portions in a break angle mode to form zigzag channels. The zigzag type bulletproof ventilation net is suitable for anti-riot and bulletproof armored cars, and does not influence ventilation and heat dissipation of engines of the armored cars, reinforces resisting and blocking effects on bullets, can effectively prevent bullet fragments from entering the ventilation net, obviously improves bulletproof safety, and enables the engines to keep normal work.
Description
Technical field
The utility model relates to vehicle motor heat dissipation technology field, relates in particular to a kind of shellproof ventilation equipment anti-riot, the bulletproof armour car engine that is applicable to.
Background technique
Anti-riot, bulletproof armour car generally all is equipped with more powerful motor, so heating value is bigger, and the ventilation equipment that not only can dispel the heat but also can be shellproof need be installed before motor.This type of facility of prior art adopts following two kinds of structures, i.e. open and close type structure and individual layer louvre type structure mostly at present.Though these two kinds of mode of structure have shellproof and draught effect, and the wretched insufficiency part is all arranged.The former is the open and close type structure, and closing can be shellproof, open and can dispel the heat, but heat radiation is difficult for, and can only the short time close use, the time slightly length will cause the gentle engine bin temperature of engine water too high and can't normally move.The latter is individual layer louvre type structure, can realize good performance of ventilating, but it has only one deck protection, when being subjected to the bullet attack, although can resist positive impact, the bullet fragment that the bullet attack produces still is easy to enter from the air intake passage of the louvre type structure of individual layer.Facts have proved that the power of bullet fragment is still very big, can cause the damage of component in engine radiator and the cabin, thereby cause the motor cisco unity malfunction.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of shellproof ventilation net of dioptric type anti-riot, the bulletproof armour car engine that is applicable to is provided; when realizing ventilation and heat; can protect in-engine component to exempt to damage and shellproof fully, thereby effectively guarantee the normal operation of motor.
The purpose of this utility model is achieved by the following technical programs:
The shellproof ventilation net of a kind of dioptric type that the utility model provides comprises backplate draw-in groove, one-level backplate; Described one-level backplate is the flap type oblique arrangement in the backplate draw-in groove; Also be provided with one deck secondary backplate at least in the described backplate draw-in groove in addition, described secondary backplate is arranged in the back of one-level backplate side by side, and is knuckle between the backplate of front and back in the end and connects and constitute tortuous passageway.The utility model is added one deck secondary backplate (also can increase by two layers, three layers or multilayer secondary backplate side by side) side by side in one-level backplate back, when not influencing the vehicle motor heat radiation, not only strengthened the effect of resisting to bullet, and its tortuous passage can stop entering of bullet fragment, thereby effectively promoted shellproof Security.
Further, secondary backplate described in the utility model is the knuckle type, so only uses two-layer backplate, also can realize three-layer protection, and forms corrugated labyrinth type air intake passage, thereby further effectively stops entering of bullet fragment.
The utlity model has following beneficial effect:
(1) the utility model is the dioptric type air intake passage; then form waveform labyrinth type air intake passage when adopting the shellproof insulation blocking of multilayer; when not influencing the vehicle motor ventilation and heat; not only strengthened the barrier effect of resisting to bullet; and can effectively prevent entering of bullet fragment; significantly improved shellproof Security, can protect interior each component of motor to exempt from damage, made motor can keep normal work.
(2) the utility model is simple and compact for structure, also can form three-layer protection and corrugated labyrinth type air intake passage when only using two-layer backplate, uses effectively simple.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model embodiment's plan view;
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: backplate draw-in groove 1, one-level backplate 2, secondary backplate 3, outer panel 4 is installed screw 5, bound edge press strip 6, upper sealing plate 7, following shrouding 8
Embodiment
Illustrated in figures 1 and 2 is the embodiment of the shellproof ventilation net of a kind of dioptric type of the utility model, comprises backplate draw-in groove 1 and is arranged on one-level backplate 2, secondary backplate 3 in the backplate draw-in groove 1.As shown in Figure 2, one-level backplate 2 is the flap type oblique arrangement; Secondary backplate 3 is knuckle type and the corresponding back that is arranged in one-level backplate 2.Be knuckle between one-level backplate 2 and the secondary backplate 3 in the end and connect, when forming three-layer protection, constitute tortuous waveform labyrinth type air intake passage.
The both sides of backplate draw-in groove 1 are provided with outer panel 4, and outer panel 4 is provided with screw 5 is installed, in order to shellproof ventilation net is fixed on headstock part solid and reliablely.In addition, around one-level backplate 2 fronts, be provided with bound edge press strip 6(and see Fig. 1), the upper end of backplate draw-in groove 1 and bottom are respectively equipped with upper sealing plate 7 and following shrouding 8, to improve steadiness and the decorative appearance of installing.
Claims (2)
1. the shellproof ventilation net of dioptric type comprises backplate draw-in groove (1), one-level backplate (2); Described one-level backplate (2) is the flap type oblique arrangement in backplate draw-in groove (1); It is characterized in that: also be provided with one deck secondary backplate (3) at least in the described backplate draw-in groove (1), described secondary backplate (3) is arranged in the back of one-level backplate (2) side by side, and is knuckle between the backplate of front and back in the end and connects and constitute tortuous passageway.
2. the shellproof ventilation net of dioptric type according to claim 1, it is characterized in that: described secondary backplate (3) is the knuckle type.
