As shown in fig. 1-2, the monitoring protection device of the present embodiment includes a housing 1, and a housing cavity 101, a temperature reduction cavity 102, a primary purging cavity 103, and a secondary purging cavity 104 are disposed in the housing 1.

One end of the accommodating cavity 101 along the axial direction of the housing 1 is provided with a monitoring board 11, and the material of the monitoring board 11 is transparent. The monitoring head of the monitoring device 700 is disposed in the accommodating chamber 101 so that the monitoring head can monitor through the monitoring board 11. If the monitoring device 700 is a thermal infrared imager, the monitoring board 11 is made of germanium glass. If the monitoring device 700 is a visible light camera, the monitoring board 11 is made of quartz glass. In order to protect the monitoring head of the monitoring device 700, the accommodating cavity 101 is a sealed cavity to prevent the smoke dust from entering the accommodating cavity 101. The monitoring device 700 may be placed in the accommodating cavity 101, which is not limited herein, and may be adjusted according to the size of the monitoring device 700 and the measurement environment.

The cooling cavity 102 is coaxially sleeved on the side surface of the accommodating cavity 101, a cooling medium is filled in the cooling cavity 102, and the cooling medium is used for cooling the accommodating cavity 101, so that the monitoring device 700 can normally work in a high-temperature environment. A first air inlet pipe 12 and a second air inlet pipe 13 are formed on the side wall of the cooling cavity 102 to continuously convey cooling media into the cooling cavity 102. Of course, in other embodiments, the second air inlet pipe 13 may also be configured as an air outlet pipe to make the cooling medium form a circular flow.

The primary purging cavity 103 can release a primary air curtain, and the primary air curtain is shielded on one side of the monitoring board 11 far away from the monitoring device 700. The secondary purge cavity 104 is capable of releasing a secondary air curtain located on a side of the primary air curtain away from the monitor panel 11. That is, the first-stage air curtain and the second-stage air curtain form a double-layer protection to prevent the smoke in the environment from approaching the monitoring board 11, thereby preventing the smoke from depositing on the monitoring board 11 and the situation that the shooting of the monitoring device 700 is blocked occurs. Therefore, the monitoring protection device can protect the monitoring equipment 700 to adapt to smoke and high-temperature environments, and the monitoring accuracy is guaranteed.

Preferably, the temperature-reducing chamber 102 includes a first end and a second end along the axial direction, the first end is closer to the monitor plate 11 than the second end, and the primary purge chamber 103 is coaxially arranged at the first end. Preferably, a primary air curtain channel 106 is formed in an inner ring of the primary purging cavity 103, a primary air flow flows out from the primary air curtain channel 106 to form a primary air curtain, and the flowing direction of the primary air flow is inclined towards the monitoring board 11. That is, the primary air curtain can be used as a protective barrier for the monitor panel 11, and can also be used for purging the monitor panel 11 to blow off the dirt such as soot deposited on the monitor panel 11, and can carry away the heat at the monitor panel 11.

Preferably, the width of the primary air curtain channel 106 is gradually reduced along the flow direction of the primary air flow to increase the flow rate of the air flow and enhance the purging strength of the air flow. And in order to make the flowing direction of the primary air flow incline towards the monitoring board 11, i.e. to form a primary air curtain similar to a conical surface form, the primary air curtain channel 106 is arranged away from the wall surface of the monitoring board 11 and inclines towards the monitoring board 11.

Preferably, the primary purge cavity 103 includes a third end and a fourth end along the axial direction, the third end is closer to the monitor plate 11 than the fourth end, and the secondary purge cavity 104 is coaxially arranged at the fourth end. Preferably, a secondary air curtain passage 107 is formed in an inner ring wall surface of the secondary purging cavity 104, a secondary air flow flows out from the secondary air curtain passage 107 to form a secondary air curtain, and a flow direction of the secondary air flow inclines towards a direction far away from the monitoring board 11. I.e. a secondary air curtain in the form of a conical surface which projects away from the monitor panel 11 to prevent smoke from entering the central cavity of the secondary purge cavity 104.

In order to further enhance the blocking effect on the smoke, preferably, a third-stage purging cavity 105 is further disposed in the casing 1, and preferably, the second-stage purging cavity 104 includes a fifth end and a sixth end along the axial direction, the fifth end is closer to the monitor plate 11 than the sixth end, and the third-stage purging cavity 105 is coaxially arranged at the sixth end.

Preferably, the inner ring wall surface of the tertiary purging cavity 105 is provided with a tertiary air curtain passage 108, tertiary air flows flow out from the tertiary air curtain passage 108 to form a tertiary air curtain, and the flow direction of the tertiary air flows inclines towards the direction far away from the monitoring board 11. I.e. to form a tertiary air curtain in the form of a conical surface that projects away from the monitor panel 11 to prevent smoke from entering the central cavity of the tertiary purge cavity 105. That is, in this embodiment, if the smoke dust contacts the monitor panel 11, the smoke dust needs to pass through the third air curtain, the second air curtain and the first air curtain, which is almost impossible to happen, so the arrangement of the first air curtain, the second air curtain and the third air curtain can effectively prevent the monitor panel 11 from contacting the smoke dust, thereby ensuring that the shooting view of the monitor device 700 has no shielding point.

In order to adapt to the ever-expanding monitoring view 800 of the monitoring device 700, preferably, the diameter of the inner ring of the primary purging cavity 103 is R1, the diameter of the inner ring of the secondary purging cavity 104 is R2, the diameter of the inner ring of the tertiary purging cavity 105 is R3, and the diameter of the monitoring plate 11 is R0, which satisfies the following conditions: r0 is more than or equal to R1 and more than or equal to R2 is more than or equal to R3. And the maximum shooting visual angle of the monitoring protection device is larger than or equal to the monitoring visual angle 800 of the monitoring equipment 700.

The monitoring protection device needs to be provided with a purging gas with certain pressure, and in order to simplify auxiliary equipment, preferably, the cooling cavity 102 is communicated with the primary purging cavity 103, the primary purging cavity 103 is communicated with the secondary purging cavity 104, and the secondary purging cavity 104 is communicated with the tertiary purging cavity 105. The gas flow requirements of each chamber of the monitoring and protection device can be met even if one set of gas supply equipment is used. And the cooling medium is used as a first-stage air curtain, a second-stage air curtain and a third-stage air curtain, so that multiple cooling effects can be formed besides shielding smoke dust, and the monitoring equipment 700 is further assisted to adapt to a high-temperature environment.

In order to ensure the flow rate of the air flow, the widths of the first-stage air curtain channel 106, the second-stage air curtain channel 107 and the third-stage air curtain channel 108 are smaller, and in order to prevent the blockage from occurring accidentally, pressure sensors can be arranged in the first-stage blowing cavity 103, the second-stage blowing cavity 104 and the third-stage blowing cavity 105, so that when the blockage occurs, the pressure sensors can be found and maintained in time, and the monitoring and protecting device can be guaranteed to play a role normally.

The embodiment further provides a monitoring system, which includes the monitoring device 700 and the monitoring protection apparatus. The monitoring system can adapt to smoke dust and high-temperature environments, and the monitoring accuracy is guaranteed.

It is to be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention.
