In order to solve the problems in the prior art, the utility model provides a pulse camera, wherein a lens heat insulation assembly is arranged in a shell of the pulse camera, so that the lens heat insulation assembly, a front panel and the front end face of an industrial personal computer are enclosed to form a heat insulation space for sealing the lens, and the lens can be effectively sealed and prevented from fogging.

Fig. 1 is a schematic structural view of a pulse camera of the present utility model. Fig. 3 is an exploded view of the pulse camera of the present utility model. As shown in fig. 1 and 3, one embodiment of the present utility model provides a pulse camera including:

a case 10, the case 10 including a housing 11 enclosing a hollow cavity, and a rear cover 12 closing a rear end surface of the housing 11, a front end surface of the housing 11 forming a transparent front panel 13;

the lens 20, the lens 20 is installed in the hollow cavity, and face the front panel 13, in order to gather the picture through the front panel 13;

the industrial personal computer 30, the industrial personal computer 30 is installed in the hollow cavity, and is located at the rear end of the lens 20; and

the lens heat insulation assembly 40, the lens heat insulation assembly 40 is formed into a cylinder shape with two open ends, and surrounds the lens 20, the front end of the lens heat insulation assembly 40 is abutted against the front panel 13, the rear end is abutted against the front end face of the industrial personal computer 30, and the lens heat insulation assembly 40, the front panel 13 and the front end face of the industrial personal computer 30 enclose to form a heat insulation space for sealing the lens 20.

In the present embodiment, the lens 20 is photographed through the front panel 13 of the housing 10, and the industrial personal computer 30 is located at the rear end of the lens 20, so that the lens 20 is disposed between the front panel 13 and the front end surface of the industrial personal computer 30.

The lens 20 may be mounted on the industrial personal computer 30 in a bayonet (e.g., inner three-blade, outer three-blade, etc.), screw, etc., or may be integrally formed with the industrial personal computer 30.

As the on-pole camera is exposed to natural conditions for a long period of time, it may experience various weather conditions, such as rain and snow weather, and the like. At the temperature, the occurrence of a fogging phenomenon may be caused due to a diurnal temperature variation; in the case of humidity, when it is exposed to rainy and snowy weather, the humidity increases, and the moisture in the case is easily accumulated.

The housing 10 forms a closed space for installing an imaging component such as the lens 20 and a control component such as the industrial personal computer 30 to provide a dust-proof and rain-proof protective housing, but the problem of fogging caused by temperature difference cannot be improved by sealing of the housing 10, and the problem of excessive humidity inside the housing cannot be solved due to the requirements of heat dissipation and the like.

A lens heat insulating member 40 for the lens 20, which is made of a heat insulating material such as foam, is provided inside the housing in this embodiment. The lens heat insulating member 40 is formed in a cylindrical shape with both ends open and a hollow cylinder formed in the middle thereof to place the lens 20 therein. And both ends of the lens heat insulating assembly 40 are respectively abutted against the inner surface of the front panel 13 and the front end surface of the industrial personal computer 30, thereby forming a heat insulating space for the lens 20. The lens heat insulation assembly 40 not only can keep the working environment temperature of the lens 20 stable, but also forms a heat insulation space independent of the hollow cavity inside the shell 10, and can insulate the moisture in the hollow cavity, thereby avoiding the generation of the fogging phenomenon from both temperature and humidity aspects.

In the present embodiment, the housing 10 may have a front end face and a rear end face, and the cross-sectional shape thereof may take a rectangular or square shape, for example, although the cross-sectional shape is specifically determined by the use situation, and the present embodiment is not limited to the shape shown in the drawings. The front face is used to form a window, in this embodiment realized as a transparent front panel 13, wherein, for sealing reasons, the front panel 13 and the side walls of the housing 10 may preferably be integrally formed as a shell 11, and the rear cover 12 is used to cover the rear face of the shell 11.

In one embodiment, the housing 10 includes a sealing ring 41, and the sealing ring 41 is disposed at a seam between the outer shell 11 and the rear cover 12, so that the housing 10 forms a watertight, dustproof, and airtight hollow cavity.

In a preferred embodiment, the outer surface of the front panel 13 is further covered with a light-transmitting material 14, which ensures both the light transmission of the lens and the protection from rain and dust. The light-transmitting material 14 is preferably high-light-transmitting glass, high-light-transmitting hard mold, high-light-transmitting composite material, or the like. The high light transmittance glass is super-white glass, is super-transparent low-iron glass, also called low-iron glass and high-transparency glass, and has light transmittance of more than 91.5%.

The light-transmitting material 14 may cover the front panel 13 or be formed as the front panel 13.

In order to ensure the normal operation of the pulse camera, heat dissipation is also a technical problem that needs to be solved by the shell. As shown in fig. 1, 2 and 3, the casing 31 of the industrial personal computer 30 has a first air inlet and a first air outlet 311 that open into the casing 31, and the first air inlet and the first air outlet 311 are opposite;

the housing 10 has a second air inlet 101 corresponding to the first air inlet position and a second air outlet 102 corresponding to the first air outlet 311 position.

The first air inlet may be located at the bottom of the casing 31, and the first air outlet 311 is located at the top of the casing 31. The second air inlet 101 is formed at the bottom of the housing 10, and the second air outlet 102 is formed at the top of the housing 10.

In the vertical direction, the first air inlet and the first air outlet 311 are aligned to form a linear heat dissipation channel for a main heat dissipation element inside the industrial personal computer 30. The second air inlet 101 is opposite to the first air inlet, and the second air outlet 102 is opposite to the first air outlet 311, so that a linear heat dissipation channel of the outside of the shell 10, the second air inlet 101, the first air inlet, the inside of the industrial personal computer 30, the first air outlet 311, the second air outlet 102, and the outside of the shell 10 is formed.

In this embodiment, a gap is necessarily present between the casing 31 of the industrial personal computer 30 and the inner surface of the casing 10 for installation, and in this embodiment, the casing 10 includes:

air inlet foam 42, wherein the air inlet foam 42 is filled between the first air inlet and the second air inlet 101 to form an air inlet channel leading from the second air inlet 101 to the first air inlet;

the air outlet foam 43 is filled between the first air outlet 311 and the second air outlet 101 to form an air outlet channel leading from the first air outlet 311 to the second air outlet 101.

The air inlet foam 42 is formed into a ring-shaped closed shape in cross section, and has a hollow shape in the middle for forming a gold-air passage, and the shape of the peripheral wall is the same as the shape of the first air inlet or the second air inlet 101. The air inlet foam 42 is filled between the first air inlet and the second air inlet 101, so that air entering from the second air inlet 101 is completely introduced into the casing 31 of the industrial personal computer 30, but not into the hollow cavity in the casing 10, so as to ensure the dustproof and waterproof effects in the casing 10. Because the foam is generally elastically deformable, the thickness of the air inlet foam 42 may be slightly greater than the gap between the first air inlet and the second air inlet 101, so that the air inlet foam 42 is elastically pressed between the casing 31 of the industrial personal computer 30 and the inner surface of the casing 10.

The shape setting and the action effect of the air outlet foam 43 are the same as those of the air inlet foam 42, and are not described in detail herein.

Further, as shown in fig. 1 and 3, the housing 10 includes a wire through hole 15, and the wire through hole 15 is formed on a side wall of the housing 10 to communicate the hollow cavity with the outside of the housing 10, and a cable 32 electrically connected to the industrial personal computer 30 passes through the wire through hole 15. The cable 32 penetrates the housing 10 from the wire through hole 15 and is communicated between the inside and the outside of the housing 10.

Due to the need for ease of installation, the aperture of the via 15 tends to be large to facilitate the passage of the cable 32, and a gap must exist between the cable 32 and the via 15. In order to prevent dust or moisture from entering the inside of the housing 10 from the wire through hole 15, the pulse camera of the present embodiment further includes:

and a heat shrinkage tube 44, wherein the heat shrinkage tube 44 is heat-shrunk around the wire passing hole 15 and the cable 32 penetrating through the wire passing hole 15 from the outside of the housing 10.

In this case, during installation, the cable 32 first penetrates through the unheated heat shrinkage tube 44, and then penetrates from the wire through hole 15 to the inside of the housing 10, so as to be electrically connected to the industrial personal computer 30. Then, one end of the heat shrinkage tube 44 is sleeved on the hole wall of the wire passing hole 15 protruding out of the outer surface of the shell 10. Finally, the heat shrinkage tube 44 is heated integrally, so that the heat shrinkage tube is used for thermally shrinking the wire through holes 15 and the part of the cable 32 outside the shell 10, thereby not only playing a role of fixing the cable 32, but also closing the exposed gaps of the wire through holes 15 and ensuring the tightness of the shell 10.

In this embodiment, the casing 10 is formed into a cube or cuboid shape, the second air inlet and the second air outlet for heat dissipation of the industrial personal computer are respectively disposed at the top and bottom of the casing 10, and the heat dissipation structures of the heat dissipation elements used in the casing 10 can be distributed on two side walls of the casing 10.

As shown in fig. 1, a heat radiation grill 16 is opened at a side wall of the housing 10 to communicate the hollow cavity with the outside of the housing 10.

For better shooting effect, the pulse camera of the present embodiment further includes:

a sunshade 50, the sunshade 50 being disposed above the housing 10 to shield a top of the housing 10 and at least partially shield a side wall of the housing 10.

The sunshade 50 is provided above the housing 10 for shielding sunlight, rainwater, dropping objects, etc. from above the housing 10. Wherein the sunshade 50 may completely shield the top of the housing 10 and partially shield the side walls of the housing 10.

As shown in fig. 3, the sunshade 50 includes a first side wall 51, a second side wall 52 corresponding to the first side wall 51, and a top plate assembly 53 connecting the first side wall 51 and the second side wall 52.

The first side wall 51 and the second side wall 52 have a connecting portion 54 extending longitudinally downward, the connecting portion 54 is fixedly connected with the side wall of the housing 10, and the connecting portion 54, the first side wall 51 and the second side wall 52 are all away from the heat dissipating grille 16, so as to ensure the heat dissipating effect of the heat dissipating grille 16.

The top plate assembly 53 may be formed in a planar shape or, as shown in fig. 3, connected with the first and second sidewalls 51 and 52 by a chamfer portion to form a shape adapted to the chamfer portion of the case 10.

In the present embodiment, the top of the housing 10 is provided with the second air outlet 102, wherein the second air outlet 102 may have a hole wall protruding from the top of the housing 10. There is a space between the planar member 53 and the top of the housing 10, and the space should be greater than the height of the wall of the second air outlet 102, thereby ensuring shielding effect and ventilation and heat dissipation effect.

The front end of the top plate assembly 53 may protrude beyond the front panel 13 of the case 10 to shield direct sunlight from the front of the case 10, preventing glare.

In this embodiment, the heat dissipation channels for the industrial personal computer and the heat dissipation channels for the hollow cavity inside the housing face different directions respectively, and are respectively disposed on two groups of different surfaces of the housing 10, so that the effects of mutual isolation and mutual noninterference can be achieved, and the dustproof and waterproof effects inside the housing 10 can be realized while the heat dissipation effects are ensured.

As shown in fig. 3, the bottom of the housing 10 of the present embodiment may be fixed to the pole by a bracket 60. The stand 60 may be a gimbal for adjusting the shooting direction of the pulse camera.

According to the above technical solution, the housing 10 forms a closed space for installing the imaging component such as the lens 20 and the control component such as the industrial personal computer 30 to provide a dust-proof and rain-proof protective housing, but the problem of fogging due to temperature difference cannot be improved by sealing of the housing 10. A lens heat insulating member 40 for the lens 20, which is made of a heat insulating material such as foam, is provided inside the housing in this embodiment. The lens heat insulating member 40 is formed in a cylindrical shape with both ends open and a hollow cylinder formed in the middle thereof to place the lens 20 therein. And both ends of the lens heat insulating assembly 40 are respectively abutted against the inner surface of the front panel 13 and the front end surface of the industrial personal computer 30, thereby forming a heat insulating space for the lens 20. The lens heat insulation assembly 40 not only can keep the working environment temperature of the lens 20 stable, but also forms a heat insulation space independent of the hollow cavity inside the shell 10, and can insulate the moisture in the hollow cavity, thereby avoiding the generation of the fogging phenomenon from both temperature and humidity aspects.

The above list of detailed descriptions is only specific to practical embodiments of the present utility model, and is not intended to limit the scope of the present utility model, and all equivalent embodiments or modifications, such as combinations, divisions or repetitions of features, without departing from the technical spirit of the present utility model are included in the scope of the present utility model.
