Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
example (b):
an infrared waterproof gun type camera is shown in fig. 1 and comprises an infrared camera body 10, wherein a waterproof anti-fog sleeve 20 is sleeved on the infrared camera body 10, one end of the waterproof anti-fog sleeve 20 extends out of the infrared camera body 10, one end of the waterproof anti-fog sleeve 20, which extends out of the infrared camera body 10, is a sleeve opening 22 and corresponds to a camera head of the infrared camera body 10, and a rain cover 30 is arranged at the top of the infrared camera body 10;
as shown in fig. 2 and 3, an air exhaust hole 24 is formed in the inner surface of the looping 22 in a surrounding manner, the air exhaust hole 24 is arranged in an inclined manner, a fan 21 is arranged on the waterproof and antifogging sleeve 20, an air duct 23 is arranged inside the waterproof and antifogging sleeve 20, and two ends of the air duct 23 are respectively connected with the air outlets of the air exhaust hole 24 and the fan 21.
In the present embodiment, as shown in fig. 1, the blower 21 is disposed on the top of the waterproof and antifogging jacket 20.
The design of fan 21 at waterproof antifog cover 20 top utilizes current rain-proof cover 30 can satisfy the rain-proof demand of fan 21 air intake position, and the security is higher.
As shown in fig. 4, the supporting structure of the rain-proof cover 30 is disposed on the infrared camera body 10 not covered by the waterproof antifogging jacket 20.
In this embodiment, the waterproof and antifogging sleeve 20 covers more than half of the infrared camera body 10, the length of the waterproof and antifogging sleeve 20 is long, so as to extend the length of the air duct 23, because the fan 21 is arranged on the side surface of the waterproof and antifogging sleeve 20, if the air duct 23 is too short, the wind power is concentrated on one side of the sleeve opening 22, and the wind power cannot be scattered from the air outlet 24, and the air duct 23 is long, so that the wind power concentration can be avoided.
The working principle of the utility model is as follows: the fan 21 inhales the wind channel 23 with external air in to it discharges to extend wind channel 23 and move to the exhaust hole 24 department of linking 22, exhaust hole 24 slope sets up, and exhaust hole 24 encircles the internal surface at linking 22, as shown by the arrow in fig. 1, the combustion gas can form an air curtain before the camera head of infrared camera body 10 in following exhaust hole 24, the air curtain can prevent external water smoke, the water droplet that breeze blown and dust and camera head contact, protect camera head.
The length of the cuff 22 extending beyond the camera head need not be very long, as long as the air exit holes 24 can be arranged, and therefore do not interfere with the shooting of the camera head.
The utility model discloses an infrared waterproof gun type camera is through establishing the antifog cover of water proof 20 at 10 overcoat of infrared camera body, and the pullover cover of waterproof antifog cover 20 is established outside camera head, utilizes fan 21 to make the wind, and wind is discharged from fan 21, air duct 23 from exhaust hole 24 at last, forms one air curtain in camera head's the place ahead, avoids external water smoke and water droplet to be close to camera head, plays good protection effect to camera head.
In another embodiment, as shown in fig. 1 and 2, the inner surface of the cuff 22 is obliquely disposed, and the exhaust holes 24 are disposed perpendicular to the inner surface of the cuff 22.
The inner surface of the sleeve opening 22 is obliquely arranged, so that the air exhaust holes 24 meeting requirements can be perpendicular to the inner surface of the sleeve opening 22, and the air exhaust holes 24 are vertically drilled during machining, so that the machining cost is lower compared with that of oblique drilling.
In another embodiment, as shown in fig. 5, one end of the waterproof anti-fog sleeve 20 away from the sleeve opening 22 extends out of the end of the infrared camera body 10, and the fan 21 is disposed at one end of the waterproof anti-fog sleeve 20 away from the sleeve opening 22.
The fan 21 is arranged at the end of the waterproof and antifogging sleeve 20, and the air blown out by the fan 21 can uniformly enter the air duct 23 with an annular cross section, so that the air discharged from each air discharging hole 24 is more uniform.
The rain cover 30 of the present embodiment is designed to be larger so as to cover the blower 21 and the cuff 22 at the same time.
In this embodiment, as shown in fig. 5, the waterproof and antifogging sleeve 20 is provided with mounting holes at positions corresponding to the supporting structure of the rain-proof cover 30 and the mounting structure of the infrared camera body 10, that is, the top surface and the bottom surface of the waterproof and antifogging sleeve 20. The air duct 23 in the waterproof and antifogging sleeve 20 is arranged around the mounting hole.
In another embodiment, as shown in fig. 5, the waterproof and antifogging sleeve 20 is provided with a tapered air guide plate 25 in the air duct 23 inside the end portion near one end of the fan 21.
Because the cross section of the waterproof and antifogging sleeve 20 is annular, namely the cross section of the air duct 23 is also annular, and the wind blown out by the fan 21 basically faces the end face of the camera body, the wind blown out by the fan 21 can be guided into the annular air duct 23 by arranging the conical air guide plate 25, so that the waste of the wind power is avoided.
In this embodiment, in order to set the air inducing plate 25, the end of the waterproof and antifogging sleeve 20 extends backwards for a certain distance after exceeding the infrared camera body 10, and then the fan 21 is set, where this section is an air inducing section, and the inside of the section is the air duct 23 with the largest diameter, and when the position of the air duct 23 near the infrared camera body 10 is a plane, part of the air blown out by the fan 21 will impact on the plane, which causes waste of wind power, so that the air blown out by the fan 21 is guided into the annular air duct 23 by setting the tapered air inducing plate 25.
In another embodiment, as shown in fig. 2, the cross-sectional area of the air duct 23 decreases from the blower 21 to the air discharge hole 24.
The design that the wind channel 23 diminishes gradually makes the velocity of flow of gas in the wind channel 23 grow gradually, is favorable to forming the air curtain more.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
