Description
Technical field
The utility model relates to a kind of industrial television semiconductor refrigeration camera protector.
Background technology
Industrial television is one of important means of modern management, control, and it can provide the image of monitored object in real time, truly, thereby makes the supervisor obtain a large amount of abundant information, to improve the efficiency of management and automatization level.In modern large enterprise,, in production control, use industrial television equipment in large quantities for the efficient operation of guaranteeing to produce that continues.
Industrial television mainly comprises video camera, video camera protector and monitor.Wherein, the video camera protector shields to the relative video camera of " tender and lovely ", is not subjected to ectocine to guarantee it, and that this protector has is dustproof, anticorrosion, anti-greasy dirt, prevent that video camera is by functions such as mechanical impacts.
Because the normal working temperature scope of video camera is-10 ℃～50 ℃, so can be divided into two types of high temperature and normal temperature to the video camera protector according to the difference of environment for use temperature: the high temperature protection device is used for more than 50 ℃, needs to install the device of water-cooled, air cooling or gas-vapor mix cooling.The normal temperature protector is used for the operational environment below 50 ℃, its general uneasy dress cooling device.But in actual use, the installation region temperature of running into the video camera protector through regular meeting is higher than 50 ℃, and on-the-spot can't providing in order to the water of cooling or the situation of source of the gas, like this, the video camera protector just can not satisfy the cooling needs.Therefore, need a kind of semiconductor refrigeration camera protector that need not the cooling water source of the gas.
Chinese patent, the patent No. are 89219209.7 to disclose a kind of industrial television camera semiconductor refrigerating protecting crust.As shown in Figure 1, the main feature of this protecting crust 1 ' is that it utilizes radiating fin 11 ' and guard shield body 14 ' to carry out natural heat dissipation; And in guard shield body 14 ', increased in one and overlapped 15 ', improved refrigerating efficiency by filling with insulation material 13 ' between guard shield body 14 ' and interior cover 15 '; Be provided with a thermostat 19 ' in the inner cover 15 ', it is subjected to from the external world by the cable access of being located on guard shield body 14 ' and the inner cover 15 ' 16 ', 17 ', when internal temperature higher, when for example being higher than 50 ℃, it starts semiconductor chilling plate 12 ' refrigeration, and the cold junction of semiconductor chilling plate 12 ' is far away apart from video camera 18 '.Therefore, this installs aspect heat radiation, owing to be the natural heat dissipation that utilizes continuous radiating fin 11 ' and outer cover body 14 ', so heat-sinking capability is comparatively limited, if ambient temperature is higher or the ventilation situation is relatively poor, its heat-sinking capability more will be had a greatly reduced quality.Like this, just be easy to cause damage, thereby do not reach effect into video camera 18 ' cooling to semiconductor chilling plate 12 '.Overall thermal design aspect at protecting crust, because it is far away that semiconductor chilling plate 12 ' leaves video camera 18 ' distance, so more refrigerating capacity is dissipated in the air of inner cover 15 ' cavity, can not give full play to the refrigeration of semiconductor chilling plate 12 ', just low to the cooling effectiveness of video camera 18 '.
Summary of the invention
The purpose of this utility model provides a kind of industrial television semiconductor refrigeration camera protector, its perfect heat-dissipating, can effectively prolong the useful life of semiconductor chilling plate, can also improve refrigerating efficiency simultaneously, give full play to the cooling effect of semiconductor chilling plate video camera.
For achieving the above object, a kind of industrial television semiconductor refrigeration camera protector that the utility model proposes, it comprises a cover body, establish semiconductor cooling piece, a video camera, a thermostat in this cover body, this thermostat is by being arranged at cable access on the cover body and getting electric from the outside and circuit connecting this semiconductor chilling plate, characteristics are, a radiator fan is set outside this cover body, and this fan circuit connects this thermostat; One heat absorbing sheet is set in this cover body, and this heat absorbing sheet is close to this video camera and is linked to each other with the cold junction of semiconductor chilling plate.
This cover body is also established a fin outward, and the hot junction of this semiconductor chilling plate connects this fin, and fan is installed on this fin;
Also establish a camera mount in this cover body, this camera mount comprises heat insulation shelf and adjustable spike;
This cover body comprises cover and covers down, is provided with between cover and the following cover on this and can opens hasp up and down;
Outside this cover body,, also be provided with dust cover in the foreign side of fan and fin;
On this time cover, be provided with the sight glass of camera photography head, this glass is fixedly arranged on this cover body by heat insulation retainer plate.
When temperature in the cover body reaches the temperature of setting, thermostat starts semiconductor chilling plate and fan, because the cold junction of semiconductor chilling plate connects heat absorbing sheet, and heat absorbing sheet is close to video camera, therefore can directly freeze to video camera, thereby avoided the refrigerating capacity loss in the air of internal cavity, improved the refrigerating efficiency of semiconductor chilling plate effectively.By being located at outer radiator fan of cover body and fin heat radiation, effectively improved heat-sinking capability; Simultaneously radiator fan and fin and internal cavity are isolated fully, have both completely cut off effectively that dust enters in the cover body in the air, and the refrigerating capacity that can prevent cover body inside again is to extraneous dissipation.In addition, also be provided with dust cover in the foreign side of fan and fin, but the dust in the filtered air has avoided when distributing the semiconductor chilling plate heat fast dust to enter into fan and cover body inside.Video camera is installed on the camera mount, and this camera mount comprises heat insulation shelf and adjustable spike, by adjusting adjustable spike, the camera body of all size model can both be close to heat absorbing sheet; Cover body comprises cover and covers down, is provided with hasp between cover and the following cover on this, can open up and down, is convenient to installation, wiring and debugging.Following cover is provided with camera photography head sight glass, is convenient to video camera and observes external circumstances, can also protect pick-up lens to avoid damaging simultaneously.
