[0044] The embodiment of the present application proposes an environmental monitoring device, which is used to monitor the environment in an oil fume environment, such as an oil fume pipe. The embodiment of the present application is described by taking an oil fume pipe as an example. Currently, the situation inside the oil fume is mostly monitored by image monitors such as cameras. However, when the image monitor is exposed to the oil fume environment for a long time, the oil fume will adhere to the lens of the image monitor, thereby blocking the field of view of the image monitor, and thus causing the image monitor to be unable to be used for a long time. Therefore, the present application proposes an environmental monitoring device, which aims to provide a protective structure on the external cover of the image monitor, so as to reduce the pollution effect of oil fume pollution on the image monitor.

[0045] Specifically, see Figures 1 to 4The environment monitoring device includes a bracket 1, a protective cover 2, a barrier part 3 and an image monitor 4. The bracket 1 is arranged inside the oil fume duct; the protective cover 2 is arranged on the bracket 1 and has a first monitoring port 21; the barrier part 3 has a second monitoring port 31, the barrier part 3 is arranged inside the protective cover 2, and the barrier part 3 has a first working state of shielding the first monitoring port 21 and a second working state of the second monitoring port 31 facing the first monitoring port 21; the image monitor 4 is arranged inside the protective cover 2, and the image monitor 4 is used to monitor the external environment when the barrier part 3 is in the second working state.

[0046] It can be understood that when monitoring is not required, the barrier part 3 is in the first working state, and the barrier part 3 can block the first monitoring port 21, that is, can block the image monitor 4. When monitoring is required, the barrier part 3 is switched from the first working state to the second working state, so that the image monitor 4, the second monitoring port 31 and the first monitoring port 21 can be directly opposite, so that the image monitor 4 can monitor the external environment. Under the action of the protective cover 2 and the barrier part 3, the pollution effect of oil fume pollution on the image monitor 4 is reduced, thereby ensuring the long-term use of the image monitor 4.

[0047] Preferably, the image monitor 4 is a camera. In addition, in order to facilitate the camera to monitor the oil fume, the environmental monitoring device may also include a light source (not shown in the drawings). The light source is arranged on the bracket 1. When the image monitor monitors the environment of the oil fume duct, the light source emits a light beam, thereby illuminating the oil fume duct, so as to improve the shooting quality of the camera.

[0048] In some embodiments, see Figures 1 to 4 There is a gap between the protective cover 2 and the blocking portion 3 to form a heat dissipation channel 5, and the heat dissipation channel 5 is connected to the first monitoring port 21 and the second monitoring port 31. It can be understood that the image monitor 4 can generate heat during operation, and the inside and outside of the protective cover 2 can be cooled through the heat dissipation channel 5, so as to improve the service life of the image monitor 4.

[0049] In some embodiments, see Figures 1 to 4, the protective cover 2 is shaped like the barrier part 3, and the barrier part 3 is rotatably arranged inside the protective cover 2, so that the bracket 1, the protective cover 2 and the barrier part 3 can enclose a dynamic sealing space. It can be understood that during the rotation of the barrier part 3, the second monitoring port 31 can be directly opposite to the first monitoring port 21, so that the barrier part 3 can be switched from the first working state to the second working state. After the image monitor 4 has finished monitoring the oil fume duct, the barrier part 3 is controlled to rotate continuously or reversely, so that the barrier part 3 can be switched from the second working state to the first working state again. Such a setting can ensure that when the barrier part 3 is in the first working state, it can achieve dynamic sealing of the image monitor 4, so as to further reduce the pollution effect of oil fume pollution on the image monitor 4.

[0050] In some embodiments, see Figures 1 to 4 The shape of the protective cover 2 is a barrel, cone, sphere or hemisphere with an axial symmetry line. Such a configuration can avoid interference between the barrier part 3 and the protective cover 2 during rotation, thereby improving the safety performance of the environmental monitoring device.

[0051] In some embodiments, see Figures 1 to 4 The bracket 1 is provided with a guide groove 11, and the barrier portion 3 is provided with a flange 32, which is slidably arranged in the guide groove 11. Such an arrangement can improve the stability of the barrier portion 3 during the rotation process to avoid the barrier portion 3 from getting stuck during the rotation process.

[0052] It should be noted that the guide groove 11 is preferably an annular groove, and correspondingly, the flange 32 is also annular, and such a configuration is provided to further ensure the stability of the blocking part 3 during the rotation process.

[0053] In some embodiments, see Figures 1 to 4 A first anti-wear member 33 is provided between the flange 32 and the guide groove 11. Such a configuration can reduce the wear between the flange 32 and the guide groove 11, thereby further improving the service life of the environment monitoring device.

[0054] Among them, the first anti-wear component 33 is preferably a thrust bearing or a gasket with self-lubricating function. The structure and use of the thrust bearing and the gasket are both existing technologies, so they are not described here in detail.

[0055] In some embodiments, see Figures 1 to 4, a plurality of first monitoring ports 21 are provided at intervals along the circumference of the protective cover 2, and / or a plurality of second monitoring ports 31 are provided at intervals along the circumference of the barrier portion 3; the environment monitoring device further comprises a mounting frame 6, the mounting frame 6 is used to fix the image monitor 4, and the mounting frame 6 is rotatably arranged inside the barrier portion 3. It can be understood that a plurality of first monitoring ports 21 are provided, and with the cooperation of the mounting frame 6, the environment monitoring device can have a plurality of monitoring positions, thereby improving the comprehensiveness of the monitoring of the environment monitoring device, and when a plurality of second monitoring ports 31 are provided, the switching time of the barrier portion 3 between the two working states can be shortened, thereby improving the use efficiency of the environment monitoring device.

[0056] In some embodiments, see Figures 1 to 4 The environment monitoring device further includes a driving unit 7, which is disposed on the bracket 1 and is simultaneously connected to the mounting frame 6 and the barrier 3 in a transmission manner, so as to drive the barrier 3 and the mounting frame 6 to rotate synchronously in opposite directions. It can be understood that the driving unit 7 has two output ends, which are respectively connected to the barrier 3 and the mounting frame 6. When the working state of the barrier 3 is switched, the two output ends respectively control the barrier 3 and the mounting frame 6 to rotate in opposite directions, so as to further shorten the switching time of the barrier 3 between the two working states, thereby further improving the use efficiency of the environment monitoring device.

[0057] In some embodiments, see Figures 1 to 4 , the mounting frame 6 is shaped like the barrier part 3, and a rotating shaft 71 is provided between the mounting frame 6 and the barrier part 3. It can be understood that the length direction of the rotating shaft 71 is consistent with the direction of the axis of symmetry of the barrier part 3. When the driving unit 7 drives the mounting frame 6 and the barrier part 3 to rotate, the mounting frame 6 and the barrier part 3 can also rotate around the axis of the rotating shaft 71. This arrangement is to further improve the stability of the barrier part 3 during the rotation process. In addition, only one hole is provided on the mounting frame 6 to expose the monitoring lens of the image monitor 4. The side wall of the mounting frame 6 can keep corresponding fit with the side wall of the barrier part 3, and then another level of dynamic sealing structure is formed between the mounting frame 6 and the barrier part 3. The two-level dynamic sealing design has a better dynamic sealing effect, so that in the first working state, it is difficult for oil smoke to enter the internal space of the mounting frame 6, and it is difficult to pollute the image monitor 4 located in the internal space of the mounting frame 6.

[0058] In some embodiments, see Figures 1 to 4The driving part 7 includes a motor 72, a first gear 73, a second gear 74, a first ring gear 75 and a second ring gear 76; the first ring gear 75 is arranged on the blocking part 3, the second ring gear 76 is arranged on the mounting frame 6, and the first ring gear 75 and the second ring gear 76 are arranged coaxially; the motor 72 is arranged on the bracket 1, the first gear 73 is arranged on the output shaft of the motor 72, and the first gear 73 is meshed with the first ring gear 75; the second gear 74 is rotatably arranged on the bracket 1, and the first gear 73 is gear-transmitted through the second gear 74 and the second ring gear 76. It can be understood that the motor 72 can drive the first gear 73 to rotate during operation. During the rotation of the first gear 73, the first gear ring 75 and the second gear 74 can be driven to rotate at the same time. Since the first gear ring 75 and the first gear 73 are internally meshed, the rotation directions of the first gear 73 and the first gear ring 75 are consistent. The first gear 73 and the second gear 74 are externally meshed. Therefore, the rotation directions of the first gear 73 and the second gear 74 are opposite. During the rotation, the second gear 74 can drive the second gear ring 76 to rotate. Since the second gear 74 and the second gear ring 76 are internally meshed, the rotation directions of the second gear 74 and the second gear ring 76 are consistent, that is, the rotation directions of the first gear ring 75 and the second gear ring 76 are opposite, and thus, under the action of the driving part 7, the blocking part 3 and the mounting frame 6 can be rotated in different directions.

[0059] Exemplarily, there are four first monitoring ports 21, and the angle between two adjacent first monitoring ports 21 is 90°, there are two second monitoring ports 31, and the two second monitoring ports 31 are arranged opposite to each other, the first gear ring 75 rotates clockwise, and the second gear ring 76 rotates counterclockwise, when the image monitor, the second monitoring port 31 and the first monitoring port 21 are facing each other, the barrier part 3 is in the second working state, when the image monitor is facing the area between the two second monitoring ports 31 on the barrier part 3, the barrier part 3 is in the first working state, and when any second monitoring port 31 is facing the area between the two first monitoring ports 21 on the protective cover 2, the barrier part 3 is also in the first working state. Such an arrangement can prevent oil stains from directly adhering to the image monitor 4, thereby ensuring the long-term use of the image monitor 4.

[0060] More specifically, there are four first monitoring ports 21 and two second monitoring ports 31. By synchronously rotating the blocking portion 3 and the mounting frame 6 in opposite directions, the image monitor 4 can monitor the environment at any of the four first monitoring ports 21. The above-mentioned design structure not only achieves a dynamic sealing effect, but also enables the image monitor 4 to monitor the external environment from four different azimuths of 0°, 90°, 180°, and 270°. More specifically, when the blocking portion 3 is in the second working state, the monitoring lens of the image monitor 4, one of the four first monitoring ports 21, and one of the two second monitoring ports 31 are just aligned, so that the external environment can be monitored; when further synchronously rotating in opposite directions, for example, the image monitor 4 rotates clockwise and the blocking portion 3 rotates counterclockwise, the second working state can be entered, and the blocking portion 3 blocks the first monitoring port 21. In this way, the image monitor 4 can pass through the four first monitoring ports 21 in sequence after one clockwise rotation and monitor the external environment at the corresponding position of the first monitoring port 21.

[0061] In some embodiments, see Figures 1 to 4 The driving part 7 further includes a second anti-wear member 77, which is disposed between the first gear ring 75 and the second gear ring 76. Such an arrangement can support the second gear ring 76 to ensure the stability of the second gear ring 76 during rotation, and the arrangement of the second anti-wear member 77 can reduce the wear between the first gear ring 75 and the second gear ring 76, thereby further improving the service life of the environment monitoring device.

[0062] Among them, the second anti-wear component 77 is preferably a thrust bearing or a gasket with self-lubricating function. The structure and use of the thrust bearing and the gasket are both existing technologies, so they are not described here in detail.

[0063] In this embodiment, a monitoring device is also proposed, the monitoring device includes the above-mentioned environmental monitoring device, and the monitoring device includes at least one of a monitoring fixed device installed in the monitored environment and a robot for mobile inspection. It can be understood that the environmental monitoring device can monitor the oil fume at a fixed point, and can also be fixed on a robot to dynamically monitor the oil fume environment, wherein the robot can be a rail-mounted robot or a quadruped robot, etc.

[0064] Obviously, the above-mentioned 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. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
