Description
TECHNICAL FIELD
[0001] The utility model relates to the field of ring cooling observation, specifically, a device for protecting a camera. BACKGROUND
[0002] Sintering ring cooling is a very important equipment in the production process of sinter, which is used to cool the sintered ore in the sintering furnace. The main function of sintering ring cooling is to rapidly cool the high-temperature ore just sintered in the sintering furnace to room temperature. This process not only helps the accumulation and transportation of ore, but also helps to improve the physical strength of ore and reduce the release of volatile elements, thereby improving the stability and efficiency in the subsequent smelting process.
[0003] During the process of sintering ring cooling, it is necessary to observe whether there is any abnormality in the finished product ore inside the sintering ring cooling. The observation of the sintered ore inside the sintering ring cooling is completed by a camera, which is inserted into the sealed groove of the sintering ring cooling and takes pictures of the finished product ore. The camera transmits the pictures to the sintering control room, and the staff can observe the finished product ore in the ring cooling through the pictures received by the control room.
[0004] Currently, the camera is fixed in the sealed cover of the sintering ring cooling. When process fluctuations occur during sintering, the temperature in the sealed cover of the sintering ring cooling will rise to about 400℃ (the temperature in the sealed cover of the ring cooling during normal production is about 150±50℃). At this time, the camera located in the sealed cover of the sintering ring cooling needs to withstand a high temperature of about 400℃, which is far beyond the working temperature range of the camera. Therefore, when process fluctuations occur during sintering, the camera in the ring cooling is easily damaged. In actual production process, the probability of process fluctuations during sintering is very high, so the camera set in the sealed cover is often damaged due to high temperature. UTILITY MODEL CONTENTS
[0005] The utility model aims to provide a device for protecting a camera, which can withdraw the camera from the sealed cover when high temperature is detected in the sealed cover, thereby protecting the camera.
[0006] In order to achieve the above-mentioned purpose, the utility model provides a device for protecting a camera, which comprises a telescopic rod, a camera connected to the front end of the telescopic rod, a movable door arranged on a sealed cover, and a thermometer arranged in the sealed cover. The telescopic rod is arranged outside the sealed cover and can extend the camera into the sealed cover through the movable door.
[0007] The thermometer detects the temperature in the sealed cover, and the thermometer is electrically connected with the movable door and the telescopic rod.
[0008] Preferably, the camera has two position states: a working state and a standby state, the camera is in the standby state when the telescopic rod is retracted, and the camera is in the working state when the telescopic rod is extended.
[0009] Preferably, the device for protecting the camera further comprises a first position sensor and a second position sensor, the first position sensor and the second position sensor are arranged on the telescopic rod respectively, the first position sensor detects whether the camera is extended to the position, and the second position sensor detects whether the camera is retracted to the position.
[0010] Preferably, the second position sensor is electrically connected with the movable door to control the movable door to be closed.
[0011] Preferably, the device for protecting the camera further comprises a cooling bin, the cooling bin is arranged outside the sealing cover, the cooling bin is provided with an opening, the opening is matched with the movable door, and the movable door can open and close the opening.
[0012] Preferably, the cooling bin comprises a bin body and a nitrogen pipeline communicated with the bin body, the nitrogen pipeline is arranged at a position away from the opening, and the camera is located in the bin body when the camera is in the standby state.
[0013] Preferably, a control valve is arranged on the nitrogen pipeline, and the control valve is electrically connected with the thermometer.
[0014] Preferably, a through hole is arranged on the bin body, the through hole is arranged opposite to the opening, the telescopic rod is matched with the through hole, and the telescopic rod can be freely extended and retracted along the axial direction of the through hole.
[0015] Preferably, a sealing ring is arranged in the through hole, and the sealing ring is used for sealing the bin body.
[0016] According to the technical scheme, the thermometer is arranged in the sealing cover to detect the real-time temperature in the sealing cover, when the temperature in the sealing cover is increased to exceed the working temperature range of the camera, the thermometer sends a high-temperature signal, the high-temperature signal controls the telescopic rod to be retracted, the telescopic rod drives the camera to exit from the position of the movable door to the outside of the sealing cover, and thus the high-temperature environment in the sealing cover does not affect the camera.
[0017] When the thermometer detects that the temperature in the sealing cover is too high, a high-temperature signal is sent, and the high-temperature signal controls the telescopic rod to be retracted.
[0018] In one embodiment, the movable door is set to a normally closed state, and when the thermometer generates a high temperature signal, the high temperature signal controls the movable door to open and the telescopic rod to retract. In order to avoid the camera interfering with the movable door when the telescopic rod retracts, the telescopic rod needs to retract after the movable door is opened to a certain extent. This function can be achieved by setting a delay, for example, the telescopic rod retracts after a delay of 10 seconds after the high temperature signal. Then the telescopic rod will wait for 10 seconds before performing the retracting action after receiving the high temperature signal. Within the 10 seconds that the telescopic rod waits, the movable door completes the opening action, so that when the telescopic rod with the camera 2 retracts to the position of the movable door, the movable door will not interfere with the camera.
[0019] A position sensor can also be provided on the movable door, which can detect whether the movable door has been opened to a position that does not interfere with the camera. When the sensor detects that the movable door has been opened enough for the camera to pass, it will send a signal that controls the telescopic rod to retract and simultaneously drives the camera out of the sealed cover.
[0020] Preferably, the movable door 3 is set to a normally open state. That is, when the camera is located in the sealed cover, the movable door is in an open state. Since the temperature in the sealed cover is not high and there is no device that needs to be protected from high temperature outside the movable door, the movable door can be set to a normally open state. In this way, the control process of the movable door is very simple, and the device structure is also simpler. In this way, when the thermometer generates a high temperature signal, the telescopic rod retracts through the normally open movable door, and the camera exits the high temperature environment with the telescopic rod, thereby achieving the protection of the camera in high temperature.
[0021] After the camera retracts, in order to avoid the high temperature gas in the sealed cover overflowing to the position of the camera and causing damage to the camera, the movable door can be controlled to close. Thus, the camera is isolated from the high temperature gas in the sealed cover, thereby better protecting the camera.
[0022] Specifically, after the telescopic rod retracts, the second position sensor detects that the telescopic rod has retracted to the position and sends a signal that the telescopic rod has retracted to the position, which controls the movable door to close. Until the thermometer sends a low temperature signal and the camera needs to extend into the sealed cover, the movable door will open.
[0023] After the camera retracts, the thermometer continues to detect the temperature in the sealed cover until the temperature in the sealed cover returns to normal. At this time, the thermometer sends a low temperature signal that controls the movable door to open and controls the telescopic rod to extend. As the telescopic rod extends, the camera returns to the sealed cover. At this time, the worker can still observe the finished product ore in the sintering ring cooling through the camera.
[0024] Therefore, the device for protecting the camera can withdraw the camera from the high-temperature area by retracting the telescopic rod when the temperature in the sealed cover is too high, thereby protecting the camera in high temperature, and when the temperature in the sealed cover decreases, the telescopic rod can send the camera back into the sealed cover, and after being sent back, the camera can still work normally.

[0034] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.
[0035] In the present application, unless otherwise stated, the orientation words contained in the terms such as "external, internal, away, relative, axial" only represent the orientation of the term in the conventional use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation on the term.
[0036] Referring to Figs. 1-2 A device for protecting a camera, the device for protecting the camera comprising a telescopic rod 1, a camera 2 connected to the front end of the telescopic rod 1, a movable door 3 arranged on a sealed cover 10, and a thermometer 4 arranged in the sealed cover 10, the telescopic rod 1 being arranged outside the sealed cover 10 and being capable of extending the camera 2 into the sealed cover 10 through the movable door 3;
[0037] The temperature meter 4 detects the temperature in the sealed cover 10, and is electrically connected with the movable door 3 and the telescopic rod 1.
[0038] Through the above technical solution, the temperature meter 4 is arranged in the sealed cover 10, and is used for detecting the real-time temperature in the sealed cover 10. When the temperature in the sealed cover 10 is increased to exceed the working temperature range of the camera 2, the temperature meter 4 sends a high-temperature signal, and the high-temperature signal controls the telescopic rod 1 to retract, and the telescopic rod 1 drives the camera 2 to exit from the position of the movable door to the outside of the sealed cover 10, so that the high-temperature environment in the sealed cover 10 does not affect the camera 2.
[0039] When the temperature meter 4 detects that the temperature in the sealed cover 10 is too high, a high-temperature signal is sent, and the high-temperature signal controls the telescopic rod 1 to retract.
[0040] In an embodiment, the movable door 3 is arranged in a normally closed state. When the temperature meter 4 generates a high-temperature signal, the high-temperature signal controls the movable door 3 to open, and the telescopic rod 1 retracts. In order to avoid the interference between the camera 2 and the movable door 3 when the telescopic rod 1 retracts, the movable door 3 needs to be opened to a certain extent before the telescopic rod 1 retracts. This function can be realized by setting a delay, for example, the telescopic rod 1 retracts after a delay of 10 seconds after the high-temperature signal. Therefore, the telescopic rod 1 waits for 10 seconds before performing the retraction action after receiving the high-temperature signal. In the 10 seconds when the telescopic rod 1 waits, the movable door 3 completes the opening action, so that when the telescopic rod 1 retracts with the camera 2 to the position of the movable door 3, the movable door 3 does not interfere with the camera 2.
[0041] A position sensor can also be arranged on the movable door 3. The position sensor can detect whether the movable door 3 has been opened to a position where the movable door 3 does not interfere with the camera 2. When the sensor detects that the movable door 3 has been opened enough for the camera 2 to pass, a signal is sent, and the signal controls the telescopic rod 1 to retract and drive the camera 2 to exit to the outside of the sealed cover 10.
[0042] Preferably, the movable door 3 is arranged in a normally open state. That is, when the camera 2 is located in the sealed cover 10, the movable door 3 is in an open state. Since the temperature in the sealed cover 10 is not high, and there is no device that needs to be protected from high temperature outside the movable door 3, the movable door 3 can be arranged in a normally open state. In this way, the control process of the movable door 3 is very simple, and the structure of the device is also simple. In this way, when the temperature meter 4 generates a high-temperature signal, the telescopic rod 1 retracts through the normally open movable door 3, and the camera 2 exits the high-temperature environment with the telescopic rod 1, thereby realizing the protection of the camera 2 in a high-temperature environment.
[0043] After the camera 2 is retracted, in order to avoid the high-temperature gas in the sealing cover 10 overflowing to the position of the camera 2 and causing damage to the camera 2, the movable door 3 can be controlled to be closed. Thus, the camera 2 is isolated from the high-temperature gas in the sealing cover 10, and the camera 2 is better protected.
[0044] Specifically, after the telescopic rod 1 is retracted, the second position sensor detects that the telescopic rod 1 is retracted to the position and sends a retraction-to-position signal, which controls the movable door 3 to be closed. Until the thermometer 4 sends a low-temperature signal, the camera 2 needs to be extended to the sealing cover 10, the movable door 3 will be opened.
[0045] After the camera 2 is retracted, the thermometer 4 continues to detect the temperature in the sealing cover 10 until the temperature in the sealing cover 10 returns to the normal state. At this time, the thermometer 4 sends a low-temperature signal, which controls the movable door 3 to be opened and controls the telescopic rod 1 to be extended. With the extension of the telescopic rod 1, the camera 2 returns to the sealing cover 10. At this time, the staff can still observe the finished product ore in the sintering ring cooling through the camera 2.
[0046] Therefore, the camera protection device can protect the camera 2 when the temperature in the sealing cover 10 is too high by retracting the telescopic rod 1 to withdraw the camera 2 from the high-temperature area. When the temperature in the sealing cover 10 decreases, the telescopic rod 1 will send the camera 2 back to the sealing cover 10. After being sent back, the camera 2 can still work normally.
[0047] In this embodiment, preferably, the camera 2 has two position states: a working state and a waiting state. When the telescopic rod 1 is retracted, the camera 2 is in the waiting state. When the telescopic rod 1 is extended, the camera 2 is in the working state.
[0048] When the temperature in the sealing cover 10 is too high, the telescopic rod 1 retracts with the camera 2. At this time, the camera 2 is located outside the sealing cover 10, and the camera 2 is in the waiting state. When the temperature in the sealing cover 10 is not high, the telescopic rod 1 extends with the camera 2. The camera 2 is located in the sealing cover 10, and the camera 2 is in the working state.
[0049] In this embodiment, preferably, the camera protection device further comprises a first position sensor and a second position sensor.

[0052] In the embodiment, preferably, the second position sensor is electrically connected with the movable door 3 to control the closing of the movable door 3.
[0053] When the second position sensor detects that the camera 2 has been withdrawn to the outside of the sealing cover 10, the second position sensor will send a signal to retract to the position, and the signal to retract to the position controls the closing of the movable door 3 to avoid damage to the camera 2 caused by the overflow of high-temperature gas in the sealing cover 10.
