[0024] Compared with the prior art, the present application has the following advantages:

[0025] The infrared camera and the imaging camera are installed at multiple positions in the engine room, for collecting infrared images and optical images of the equipment in the engine room and displaying on the computer screen, because the temperature of the equipment will gradually change during use, especially the temperature of the bearing position gradually increases with the increase of use time, therefore the set temperature analysis module can process the infrared images, extract the temperature information of the equipment, record the temperature increase of the equipment during normal operation, and analyze the collected temperature data and compare with the normal temperature data stored in the database, when the temperature of the equipment exceeds the normal range, the system determines that the temperature is abnormal, at this time an alarm signal is sent out through the set alarm module to remind the operator to handle, thereby improving the safety and avoiding accidents.

[0027] By movably connecting the body with the sleeve via a movable seat, the movable seat can drive the infrared camera and the imaging camera to deflect relative to the sleeve and the mounting bracket, thereby adjusting the shooting angle of the camera. This allows the camera to be adaptively adjusted according to the position of the equipment in the ship's engine room. There is no need to install the camera at a specific position in the ship's engine room due to the fixed angle of the camera, thereby improving the camera installation efficiency and ensuring the temperature monitoring effect of the equipment at various positions inside the ship.

[0028] By setting a positioning component, the position status of the sleeve and the movable seat can be locked and restricted, avoiding the infrared camera and the imaging camera from shaking after the position is adjusted, making it impossible for the camera to accurately shoot the equipment, affecting the temperature monitoring effect of the equipment in the ship's engine room; and when the positioning component is actuated, it drives the limit assembly to act, limiting the position of the piston plate in the hydraulic chamber, so that the hydraulic oil capacity in the hydraulic chamber will no longer change, thereby ensuring the abutment and clamping state of the rubber head at the end of the sliding rod to the installation position, avoiding the clamping stability of the clamp seat being affected when used for a long time or in an environment with large vibrations, causing the camera to loosen or fall off from the installation position in the ship's engine room, thereby effectively ensuring the monitoring effect of the equipment temperature.

[0045] In use, the infrared camera 11 and the imaging camera 12 are first mounted at multiple positions in the cabin by the fixing mechanism, to ensure that all equipment can be covered, for collecting infrared images and optical images of the equipment in the cabin, and displaying on the computer screen. It should be noted that the temperature of the equipment will gradually change during use, especially the temperature of the bearing position of the equipment in the cabin will gradually increase with the increase of use time, so that the infrared camera 11 can collect the infrared images of the equipment in the cabin and obtain the surface temperature of the equipment, record the temperature rise of the equipment during normal operation, and then process the infrared images by the temperature analysis module 14, extract the temperature information of the equipment, and analyze the collected temperature data, and compare with the normal temperature data stored in the database 13 in stages. Through comparison with the data in the database 13, the system can automatically identify temperature abnormalities and reduce manual intervention. When the temperature of a certain equipment is detected to be out of the normal range, the system determines that the temperature is abnormal, and at this time, the alarm module 15 set sends an alarm signal to remind the operator to handle, and the system automatically predicts the equipment maintenance time, has high degree of automation, reduces the dependence on manual monitoring, can timely find equipment abnormalities through real-time monitoring of equipment temperature, avoids accidents, improves safety, and through the fixing mechanism, the infrared camera 11 and the imaging camera 12 can be quickly installed at each position in the cabin, facilitating accurate monitoring of the temperature at each position in the cabin, and ensuring safe operation of the equipment in the cabin.

[0046] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , as a preferred embodiment, on the basis of the above mode, further, the clamping part 3 includes first elastic expansion rods 301 arranged on both sides of the mounting bracket 2, a connecting frame 302 connected to the movable end of the first elastic expansion rod 301, and a clamping seat 303 connected to the connecting frame 302, and the clamping seat 303 is provided with a clamping assembly; the staff drives the clamping seat 303 on both sides of the mounting bracket 2 to separate the clamping seat 303 on both sides of the mounting bracket 2, the first elastic expansion rod 301 is stretched, the distance between the two clamping seats 303 is moved to the maximum, so that the clamping distance between the two clamping seats 303 adapts to the installation position in the cabin, and then the force on the clamping seat 303 is released, the first elastic expansion rod 301 pulls back the clamping seat 303, and the clamping seat 303 on both sides of the mounting bracket 2 is clamped to the mounting position by the clamping assembly, so as to facilitate the installation of the infrared camera 11 and the imaging camera 12 at different positions in the cabin, and further facilitate accurate monitoring of the temperature at each position in the cabin;

[0047] It should be noted that the clamping assembly includes a plurality of piston blocks 5 slidingly connected in the clamping seat 303, a slide rod 501 corresponding to each piston block 5, and a rubber head 502 provided at the end of the slide rod 501.

[0048] When it is necessary to install the infrared camera 11 and the imaging camera 12, the body 1 is placed at the installation position, and the two clamping seats 303 are moved close to each other under the pulling of the first elastic extension rod 301. When the slide rod 501 in the clamping seat 303 is in contact with the cabin installation position, it is pressed and slides towards the inside of the clamping seat 303. The piston block 5 is pressed to extrude the first elastic element 503, and the first elastic element 503 is also pressed to rebound and push the slide rod 501. A plurality of slide rods 501 can be in close contact with the irregular installation position, so as to facilitate the clamping and fixing of the installation support 2 and the infrared camera 11 and the imaging camera 12 provided thereon at different positions of the cabin, thereby facilitating temperature monitoring of different positions inside the cabin. The end of the slide rod 501 is provided with a rubber head 502 to contact and resist the installation position, which can improve the friction between the slide rod 501 and the installation position of the cabin. Not only can the stability of the installation support 2 be improved, but also the friction between the slide rod 501 and the installation position of the cabin can be prevented from being damaged due to long-term resistance.

[0049] As shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 9 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the movable seat 102 includes a ball hinge head 1021 and a base 1022 fixedly connected with the ball hinge head 1021. The infrared camera 11 and the imaging camera 12 are respectively arranged on both sides of the base 1022. The sleeve 101 is provided with a ball hinge groove 1011 for the movement of the ball hinge head 1021. The positioning component 4 includes a screw rod 401 symmetrically arranged on both sides of the sleeve 101, a knob 402 arranged at the end of the screw rod 401, an arc-shaped clamp plate 403 connected with the end of the screw rod 401 away from the knob 402, and a rubber pad 404 arranged on the arc-shaped clamp plate 403 and in movable abutment with the ball hinge head 1021.

The arc-shaped clamping plate 403 is in contact with the ball joint 1021 through the rubber pad 404, which, on the one hand, increases the contact surface with the ball joint 1021 and improves the rotation resistance of the ball joint 1021, and on the other hand, prevents the ball joint 1021 and the arc-shaped clamping plate 403 from being damaged due to hard contact, thereby ensuring their service life.

[0051] It should be noted that, in order to enable the arc-shaped clamping plates 403 on both sides of the sleeve 101 to clamp the ball joint 1021 at the same time, the sleeve 101 is rotatably connected to a bevel gear 7 that is slidably connected to the screw 401 through a support, and the sleeve 101 is rotatably connected to a bevel gear ring 701 that meshes with the bevel gear 7.

The rotating bevel gear 7 is meshed with the bevel gear ring 701 on the outside of the sleeve 101 for transmission. The bevel gear ring 701 is meshed with the bevel gear 7 on the other side of the sleeve 101 for transmission, so that the bevel gear 7 on the other side drives the screw 401 slidably connected to it to rotate through the guide bar 702, thereby making the screws 401 on both sides of the sleeve 101 rotate synchronously, realizing the clamping action of the two arc-shaped clamping plates 403 on the ball joint 1021.
