[0016] Compared with the prior art, the above-described technical solution of the present invention has the following advantages:

[0017] The present invention discloses a cooling device for a blast furnace tuyeres camera. This device comprises a first fixing ring, a second fixing ring, and a round rod. The first fixing ring is installed at the end of the air blowing pipe, the second fixing ring is installed at the head of the camera body, and the round rod is installed between the first and second fixing rings. This creates a hollow space between the camera body and the high-temperature air blowing pipe, allowing for natural air circulation and heat insulation. Now, with the air source valve closed, nitrogen cooling is no longer used, achieving complete natural cooling. Previously, without nitrogen, the temperature reached as high as 80°C, severely impacting the safety of the camera body.

A limiting nut and a fastening nut are respectively provided on both sides of the second fixing ring. The limiting nut limits the closest distance between the second fixing ring and the first fixing ring, while the fastening nut limits the farthest distance between them. Since the round rod is easily subjected to thermal expansion and contraction in the high-temperature blast furnace, the second fixing ring will compress the sliding tube, which in turn compresses the damper and spring, causing the rod to slide within the sleeve. This achieves the adaptive movement of the second fixing ring and also protects the round rod.

[0019] The present invention discloses a cooling device for a blast furnace tuyeres camera. By incorporating a temperature sensor and a reciprocating lead screw, the temperature sensor monitors the temperature at the end of the blowpipe and transmits the temperature signal to the system. The system then controls the activation of a motor and the movement of a moving plate. The motor's output shaft drives the reciprocating lead screw to rotate, which in turn moves the moving plate, which in turn moves the blowpipe. This adjusts the distance between the blowpipe and the camera body, facilitating cooling of the camera body by adjusting the position of the blowpipe within different high-temperature ranges.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] like Figures 1 to 7 As shown in the figure, a cooling device for a blast furnace tuyeres camera according to an embodiment of the present invention includes an air blowing pipe 1, a camera body 2, and a cooling pipe 3. A first fixing ring 11 is slidably connected to the outer wall of the air blowing pipe 1. A second fixing ring 21 is threadedly connected to the outer wall of the head of the camera body 2. Two round rods 4 are symmetrically inserted between the first fixing ring 11 and the second fixing ring 21. One end of each round rod 4 is fixed by a clamping mechanism, and an adaptive adjustment mechanism is provided on one side of each round rod 4 on the second fixing ring 21. The cooling pipe 3 is threadedly connected to the end of the camera body 2 to protect the signal line of the camera body 2.

[0032] The first fixing ring 11, the round rod 4, and the second fixing rod provided by this invention ensure normal operation of the air vent camera even when nitrogen is not used. The first fixing ring 11 is installed at the end of the air blowing pipe 1, the second fixing ring 21 is installed at the head of the camera body 2, and the round rod 4 is installed between the first fixing ring 11 and the second fixing ring 21. This creates a hollow space between the camera body 2 and the high-temperature air blowing pipe 1, allowing for natural air circulation and heat insulation. Now, with the air source valve closed, nitrogen cooling is no longer used, and natural cooling is achieved entirely. Previously, without nitrogen, the temperature reached as high as 80°C, seriously affecting the safety of the camera body 2. After the improvement, the temperature of the camera body 2 is around 40°C, consistent with the ambient temperature, and the image quality is not affected, thus achieving the cooling function of the camera body 2. The signal line of the camera body 2 is connected to the cooling pipe 3, which facilitates heat insulation protection for the signal line of the camera body 2. The outer side of the camera body 2 is wrapped with a stainless steel corrugated plate as a fireproof cover.

[0033] like Figure 2 and Figure 3 As shown, the clamping mechanism includes V-shaped blocks 116 fixedly attached to the outer wall of the first fixed ring 11. Two fixed plates 111 are fixedly attached to the outer wall of the first fixed ring 11. A bidirectional lead screw 112 is rotatably connected between the two fixed plates 111 via a bearing. A screw block 115 is fixedly attached to one end of each bidirectional lead screw 112. Two V-shaped plates 114 are threadedly connected to each bidirectional lead screw 112. The two V-shaped plates 114 and the V-shaped blocks 116 clamp the round rod 4 in the middle.

[0034] In use, the clamping mechanism provided by the present invention fixes the round rod 4 by placing the round rod 4 inside the V-block 116, then rotating the rotating block 115, which in turn drives the bidirectional lead screw 112 to rotate, and the bidirectional lead screw 112 to move the V-plate 114 until the V-plate 114 and the V-block 116 work together to clamp the round rod 4, thus fixing the round rod 4. The opening angle of the V-block 116 is set to 90°-120°.

[0035] like Figure 3 As shown, two guide rods 113 are fixedly connected between the two fixed plates 111, and the V-shaped plates 114 are slidably connected to the two guide rods 113.

[0036] When the guide rod 113 provided by the present invention is in use, the V-shaped plate 114 slides on the guide rod 113 when sliding, and the guide rod 113 limits the V-shaped plate 114 to slide in the horizontal direction.

[0037] like Figure 4 and Figure 5As shown, each of the adaptive adjustment mechanisms includes a limiting nut 22 threaded to one end of the round rod 4, a fastening nut 23 threaded to the end of the round rod 4, a sleeve 24 slidably connected to the outside of the round rod 4, a sliding tube 25 slidably connected inside the sleeve 24, a damper 26 fixed to one end of the sliding tube 25, and a spring 27 sleeved on the outside of the damper 26.

[0038] The adaptive adjustment mechanism provided by this invention is used to fix the other end of the round rod 4. The second fixing ring 21 is provided with a limiting nut 22 and a fastening nut 23 on both sides. The limiting nut 22 is used to limit the closest distance between the second fixing ring 21 and the first fixing ring 11, and the fastening nut 23 is used to limit the farthest distance between the second fixing ring 21 and the first fixing ring 11. The round rod 4 is easily subjected to thermal expansion and contraction in the high-temperature blast furnace. Therefore, the second fixing ring 21 will squeeze the sliding tube 25, and the sliding tube 25 will squeeze the damper 26 and the spring 27, sliding within the sleeve 24, thereby realizing the adaptive movement of the second fixing ring 21 and also protecting the round rod 4.

[0039] like Figure 1 and Figure 2 As shown, two limiting rods 12 are fixedly connected to the outer wall of the air blowing pipe 1, and two limiting grooves 117 are opened on the inner side wall of the first fixing ring 11. The limiting rods 12 are slidably connected in the limiting grooves 117.

[0040] When the limiting rod 12 provided by the present invention is in use, the air blowing pipe 1 drives the limiting rod 12 to move during the movement of the air blowing pipe 1. The limiting rod 12 slides in the first fixed ring 11 and limits the movement of the air blowing pipe 1 in the horizontal direction.

[0041] like Figure 6 As shown, an installation plate 13 is slidably connected to the outer wall of the gas blowing pipe 1, and an installation frame 131 is fixedly connected to the outer wall of the first fixing ring 11. The installation frame 131 is welded to the inner wall of the blast furnace, and a motor 135 is fixedly connected to the installation frame 131. The output shaft of the motor 135 is rotatably connected to the installation frame 131 through a bearing. A reciprocating screw 133 is fixedly connected to the output shaft of the motor 135. One end of the reciprocating screw 133 is rotatably connected to the installation plate 13 through a bearing. A moving plate 132 is threadedly connected to the reciprocating screw 133, and the moving plate 132 is fixedly connected to the side wall of the gas blowing pipe 1. A protective cover is provided on the outside of the motor 135.

[0042] When the connecting plate and reciprocating screw 133 provided by the present invention are used, the motor 135 is turned on according to the temperature inside the blast furnace. The output shaft of the motor 135 drives the reciprocating screw 133 to rotate, which in turn drives the moving plate 132 to move. The moving plate 132 then drives the air blow pipe 1 to move, thereby adjusting the distance between the air blow pipe 1 and the camera body 2. This makes it suitable for use in different high-temperature environments. The position of the air blow pipe 1 can be adjusted to facilitate the cooling of the camera body 2.

[0043] like Figure 7 As shown, two crossbars 134 are fixedly connected between the mounting plate 13 and the mounting bracket 131, and the movable plate 132 is slidably connected to the two crossbars 134.

[0044] When the crossbar 134 provided by the present invention is in use, the moving plate 132 slides on the crossbar 134 during the movement process, and the crossbar 134 limits the moving plate 132 to move in the horizontal direction.

[0045] like Figure 7 As shown, a side plate 137 is fixedly connected to the side wall of the camera body 2, and two sliding rods 136 are fixedly connected to the side wall of the mounting bracket 131. The sliding rods 136 are slidably connected to the side plate 137.

[0046] When the slide bar 136 provided by the present invention is in use, in order to ensure the center alignment between the air blow pipe 1 and the camera body 2, the camera body 2 is driven to move by the second fixing ring 21. During the movement, the camera body 2 drives the side plate 137 to move. The side plate 137 slides on the two slide bars 136, and the slide bars 136 limit the camera body 2 to move axially.

[0047] like Figure 6 As shown, a temperature sensor 14 is fixedly connected to the inner wall of the air blow pipe 1 near the camera body 2, and the temperature sensor 14 is electrically connected to the motor 135.

[0048] The temperature sensor 14 provided by this invention is used to monitor the temperature at the end of the air blowpipe 1 during use, and then transmits the temperature signal to the system. The system controls the motor 135 to start and controls the movement of the moving plate 132, thereby adjusting the distance between the air blowpipe 1 and the camera body 2. For example, if the temperature at the end of the air blowpipe 1 is 80 degrees Celsius as monitored by the temperature sensor 14, it is usually necessary to adjust the gap between the air blowpipe 1 and the camera body 2 to 20 mm.

[0049] like Figure 1 and Figure 2 As shown, multiple fins 41 are linearly arranged and fixed on the outer wall of the round rod 4, and the round rod 4 is made of steel bars with a diameter of 4mm.

[0050] When in use, the fins 41 provided by the present invention expand the heat dissipation area, accelerate the heat dissipation, and reduce the heat transfer from the round rod 4 to the camera body 2; the round rod 4 is a steel bar with a diameter of 4mm, which has a certain rigidity.

[0051] Working Principle: To ensure normal operation of the camera even when nitrogen is no longer used, a first fixing ring 11 is installed at the end of the air blowing pipe 1, and a second fixing ring 21 is installed at the head of the camera body 2. A round rod 4 is installed between the first fixing ring 11 and the second fixing ring 21. This creates a hollow space between the camera body 2 and the high-temperature air blowing pipe 1, allowing for natural air circulation and heat insulation. Now, with the air source valve closed, nitrogen cooling is no longer used, and natural cooling is achieved entirely. Previously, without nitrogen, the temperature reached as high as 80°C, seriously affecting the safety of the camera body 2. After the improvement, the temperature of the camera body 2 is around 40°C, consistent with the ambient temperature, and the image quality is not affected, thus achieving the cooling function of the camera body 2. The signal line of the camera body 2 is connected to the cooling pipe 3, which facilitates heat insulation protection for the signal line of the camera body 2. The outer side of the camera body 2 is wrapped with a stainless steel corrugated plate as a fireproof cover.

[0052] To fix the round rod 4, the round rod 4 is placed inside the V-block 116, and then the rotating block 115 is rotated. The rotating block 115 drives the bidirectional lead screw 112 to rotate, and the bidirectional lead screw 112 drives the V-plate 114 to move until the V-plate 114 and the V-block 116 work together to clamp the round rod 4, thus fixing the round rod 4. The opening angle of the V-block 116 is set to 90°-120°. When the V-plate 114 slides, it slides on the guide rod 113, and the guide rod 113 limits the V-plate 114 to slide in the horizontal direction.

[0053] The adaptive adjustment mechanism is used to fix the other end of the round rod 4. The second fixing ring 21 is provided with a limiting nut 22 and a fastening nut 23 on both sides. The limiting nut 22 is used to limit the closest distance between the second fixing ring 21 and the first fixing ring 11, and the fastening nut 23 is used to limit the farthest distance between the second fixing ring 21 and the first fixing ring 11. The round rod 4 is easily subjected to thermal expansion and contraction in the high temperature of the blast furnace. Therefore, the second fixing ring 21 will squeeze the sliding tube 25, and the sliding tube 25 will squeeze the damper 26 and the spring 27, sliding within the sleeve 24, thereby realizing the adaptive movement of the second fixing ring 21 and protecting the round rod 4.

[0054] Temperature sensor 14 is used to monitor the temperature at the end of air blowpipe 1 during use, and then transmits the temperature signal to the system. The system controls the start of motor 135 and controls the movement of moving plate 132. The output shaft of motor 135 drives reciprocating screw 133 to rotate, which in turn drives moving plate 132 to move. Moving plate 132 then drives air blowpipe 1 to move, thereby adjusting the distance between air blowpipe 1 and camera body 2. This allows for adjustment of the position of air blowpipe 1 within different high-temperature ranges, facilitating cooling of camera body 2.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
