Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature industrial televisions, and more specifically, to a camera device. Background Art

[0002] At present, high-temperature industrial television for imaging in high-temperature furnaces is a special closed-circuit television equipment used in high-temperature environments. It is widely used in industrial high-temperature furnaces such as heating furnaces, steam boilers, sintering furnaces, etc. in metallurgy, electric power, building materials, light industry, chemical industry and other industries. The equipment can extend the camera lens directly into the furnace to observe the conditions of the materials and flame shape in the furnace, which is convenient for centralized scheduling and automatic monitoring of the production process, and realizes the function of ensuring production safety and improving product quality. However, after the installation of the entire high-temperature industrial television and the furnace wall, the existing device needs to adjust the distance between the camera and the object observed in the furnace, and the adjustment process is relatively cumbersome.

[0003] After searching, a Chinese patent with publication number CN216700177U discloses a high-temperature industrial television for imaging inside a blast furnace. The structure sets a compression spring, and by rotating a fixed ring on one side, the elasticity of the compression spring can be used to adjust the position of the camera, making the adjustment of the camera position more convenient. By setting the first and second cold air inlet pipes and the inlet and outlet water pipes, the temperature of the built-in sleeve and the protective sleeve can be reduced to cool the environment around the camera and extend its service life.

[0004] However, in actual use, since the camera of this structure is set inside the protective sleeve through an installation sleeve, when it is necessary to adjust the distance between the camera and the object to be observed in the furnace body, the camera needs to be pushed forward and close to the object for observation, and the length of the protective sleeve set by this structure is fixed, so the maximum adjustable distance of the camera can only be to the top of the protective sleeve. If this structure is installed inside furnaces of different models and sizes, it is necessary to replace the protective sleeve with a matching length according to the furnace body and install the camera inside the furnace body, resulting in low adaptability of the structure. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a camera device to solve the problems raised in the above background technology.

The spring 6 is arranged between the second protective sleeve 3 and the fixing seat 5. When the installation sleeve 2 is turned, the camera 13 can be driven forward. At the same time, the side where the inner wall of the second protective sleeve 3 contacts the installation sleeve 2 is pushed by the installation sleeve 2, so that the second protective sleeve 3 can move. At the same time, the connecting telescopic sleeve 4 and the spring 6 will be unfolded due to the movement of the second protective sleeve 3, thereby achieving the function of adjusting the length of the first protective sleeve 1. When one end of the installation sleeve 2 moves to be flush with the inner cavity of the first protective sleeve 1, the spring 6 can drive the second protective sleeve 3 to automatically reset through its own elasticity, so that the device can be adapted to furnaces of different sizes to improve the detection effect.

[0020] As attached Figure 2-4 As shown, two limit grooves 10 are symmetrically provided on the inner wall of the second protective sleeve 3, and sliders 16 are slidably connected inside the limit grooves 10. The surfaces of the two sliders 16 are commonly fixedly connected with limit rings 17, and the limit ring 17 is fixedly sleeved on the outside of one end of the first protective sleeve 1; the installation sleeve 2 and the second protective sleeve 3 are both provided with observation holes 14 at one end, and the installation sleeve 2 is fixedly provided with a plurality of support rods 20 on the surface relative to the observation holes 14, and a ball 21 is rotatably clamped at one end of the support rod 20; the inner wall of the second protective sleeve 3 is provided with a sliding groove adapted to the ball 21 corresponding to the ball 21.

[0021] As attached Figure 2 As shown, a second sealing gasket 15 is fixedly provided in the inner cavity of one end of the first protective sleeve 1 connected to the mounting sleeve 2, and a first sealing gasket 11 is fixedly connected to the inner cavity of one end of the second protective sleeve 3 connected to the first protective sleeve 1. The mounting sleeve 2 pushes the second protective sleeve 3 forward while rotating, and the ball 21 can contact with the second protective sleeve 3 to reduce the wear of the mounting sleeve 2. At the same time, the slider 16 slides inside the limiting groove 10 to prevent the second protective sleeve 3 from rotating during movement, thereby improving the stability of the second protective sleeve 3 during movement.

[0022] As attached Figure 2As shown, two water inlets 7 are symmetrically arranged on the surface of the first protective cover 1, and the water inlets 7 are connected with the inner cavity of the first protective cover 1; the first protective cover 1 forms a cooling chamber 9 between the first sealing gasket 11 and the installation cover 2, so that when the camera 13 enters the interior of the furnace body for observation, it can cool down the outside of the installation cover 2 by continuously injecting cold water into the cooling chamber 9, thereby extending the service life of the camera 13.

[0023] Working principle of the utility model: when the device is in use, firstly, the first protective cover 1 is fixedly connected to the surface of the furnace body through the mounting plate 8, and then the camera 13 is installed inside the mounting cover 2 by rotating and twisting the mounting plate 12, and the water pipe is connected to the outside of the water inlet 7. When detecting objects, the situation of the objects in the furnace body can be observed through the camera 13, and at the same time, cold water is added to the cooling chamber 9 through the water inlet 7. When the water inside the cooling chamber 9 is full, it will flow out from another water inlet 7, so that there is continuous cold water in the cooling chamber 9, so that the water source can cool the surface of the camera 13 when the camera 13 observes the object, thereby extending the service life of the camera 13;

[0024] If it is necessary to adjust the distance between the camera 13 and the object during detection, the camera 13 is driven forward by twisting the mounting sleeve 2. At the same time, the thrust generated by the extrusion of the mounting sleeve 2 on the side where the inner wall of the second protective sleeve 3 contacts the mounting sleeve 2 pushes the second protective sleeve 3 to achieve the function of adjusting the length of the first protective sleeve 1. At the same time, the telescopic sleeve 4 and the spring 6 connected will be expanded due to the movement of the second protective sleeve 3, thereby achieving the function of adapting to furnaces of different sizes and effectively improving the detection effect.
