One side of the sealing welding rod 131 is attached to the inner side of the lens outer barrel 110, and the other side of the sealing welding rod 131 is attached to the lens cover 130. The position where the sealing welding rod 131 contacts the lens outer barrel 110 and the lens cover 130 is seal-welded, that is, there are two welding traces on the sealing welding rod 131, one is the position where the sealing welding rod 131 and the lens outer barrel 110 overlap, and the other is the position where the sealing welding rod 131 and the lens cover 130 overlap.

[0028] like Figure 3 , Figure 5 , Figure 6 as well as Figure 7As shown, a cooling gap 111 is left between the lens outer barrel 110 and the lens inner barrel 120, and the cooling gap 111 is blocked by the lens cover 130 and the base device 30.

The protrusions also abut against the partition 112. More specifically, one end of the partition 112 is fixed on the base device 30, and the other end of the partition 112 is supported by the support ring 113, so that the position of the partition 112 in the cooling gap 111 can be fixed.

[0029] Preferably, if Figures 2 to 8 As shown, the barrel device 10 also includes a lens air inlet pipe 114 , a lens air outlet pipe 115 and an inner barrel air inlet pipe 116 installed on the lens outer barrel 110 .

The inner barrel air inlet pipe 116 is connected to the interior of the lens inner barrel 120 through the lens outer barrel 110 and the partition 112.

[0031] The inner cylinder 150 is arranged inside the outer cylinder 140, and a cooling gap is also left between the outer cylinder 140 and the inner cylinder 150. The cover plate 160 and the base device 30 are respectively arranged at both ends of the outer cylinder 140 and the inner cylinder 150.

The machine body cover plate 160 is provided with a cooling hole 162, and the gas in the inner cylinder 150 of the machine body can be discharged from the cooling hole 162. The cooling gas can be injected into the cooling gap between the outer cylinder 140 of the machine body and the inner cylinder 150 of the machine body through the machine body air inlet pipe 141, and the cooling gas bypasses the partition bar 151 and enters the cooling gap on the other side, and the cooling gas can be discharged from the machine body air outlet pipe 142, thereby completing the cooling protection of the inner cylinder 150 of the machine body.

[0032] like Figure 2 , Figure 5 , Figure 6 as well as Figure 7 As shown, the body device 20 includes a lens body 210 and an imaging body 220. The lens body 210 is accommodated in the lens inner barrel 120. A lens support ring 211 is sleeved on the lens body 210. The lens support ring 211 is fixedly sleeved on the lens body 210. The convex point of the lens support ring 211 contacts the inner wall of the lens inner barrel 120. Under the fixation of the lens support ring 211, the position of the lens body 210 relative to the lens cover 130 can be maintained. The lens cover 130 is provided with a lens through hole 132. The end of the lens body 210 is arranged corresponding to the lens through hole 132. The lens body 210 can collect light through the lens through hole 132 and transmit the light to the imaging body 220. The imaging body 220 is accommodated in the body inner barrel 150. The imaging body 220 is fixedly mounted on the base device 30. The imaging body 220 can analyze the light and form a video signal of the image to be transmitted to the terminal.

[0033] like Figure 2 and Figure 5As shown, the base device 30 includes a connecting plate 310, a mounting frame 320 and an air chamber block 330. The lens outer barrel 110 and the partition plate 112 are fixedly inserted on one side of the connecting plate 310, and the lens inner barrel 120 is arranged through the connecting plate 310. The relative positions of the lens inner barrel 120 and the lens outer barrel 110 can be fixed by cooperating with the lens cover plate 130 and the support ring 113. The sealing ring 161 is fixed on the connecting plate 310. The connecting plate 310 is provided with a through hole, and the lens body 210 and the lens inner barrel 120 are both penetrated by the through hole. The mounting frame 320 is fixedly installed on the side of the connecting plate 310 away from the lens inner barrel 120, and the imaging body 220 is fixedly installed on the mounting frame 320. The air chamber block 330 is fixedly mounted on the connecting plate 310. The air chamber block 330 is arranged around the through hole of the connecting plate 310. A plurality of air holes are opened on the air chamber block 330. The air holes are connected to the space on both sides of the base device 30. The air chamber block 330 is also fixedly mounted on the lens body 210. The air chamber block 330 is located at the center of gravity of the body device 20, which can prevent the lens body 210 and the imaging body 220 from tilting after being connected.

[0034] When the above is in use, the outer tube 140 is first used to fix it on the furnace wall, and then the lens body 210 is extended into the blast furnace. The lens body 210 collects the light in the blast furnace through the lens through hole 132 on the lens cover 130. The lens body 210 collects the light and transmits it to the imaging body 220. The imaging body 220 analyzes the light and generates a signal to transmit to the video terminal. The video terminal provides a visual monitoring picture to the staff. During the startup process, cooling gas is injected through the lens air inlet pipe 114, the inner cylinder air inlet pipe 116 and the body air inlet pipe 141. The cooling gas injected into the lens air inlet pipe 114 bypasses the partition 112, flows around the lens inner cylinder 120, and is discharged from the lens air outlet pipe 115 carrying the heat in the inner cylinder 120. The inner cylinder air inlet pipe 116 injects cooling gas into the lens inner cylinder 120. The gas in the lens inner cylinder 120 enters the body inner cylinder 150 through the air holes of the air chamber block 330 and is discharged through the cooling holes 162 on the body cover 160. The body air inlet pipe 141 injects cooling gas into the interlayer between the body inner cylinder 150 and the body outer cylinder 140. The cooling gas bypasses the partition bar 151 and is discharged through the body air outlet pipe 142. In the above process, due to the double weld sealing of the sealing electrode 131 on the lens cover 130, the sealing degree of the lens cover 130 is ensured, the invasion of dust into the industrial TV is reduced, and the service life of the industrial TV is increased.

[0035] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description.
