[0038] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0039] Example 1

[0040] See also Figure 1 - Figure 9, a video surveillance device for a hazardous chemical warehouse includes a monitor 3, a lens is provided on the monitor 3, and also includes: a mounting base 1; a rotating assembly 2 for driving the monitor 3 to rotate; the rotating assembly 2 includes a rotating shaft 21, the rotating shaft 21 is rotatably mounted on the bottom of the mounting base 1, the bottom end of the rotating shaft 21 is fixedly connected to the connecting base 22, and the mounting bracket 23 is fixedly mounted on the connecting base 22, and the monitor 3 is hinged on the mounting bracket 23, and a motor 24 is installed on the mounting base 1, and the output end of the motor 24 is fixedly connected to the first bevel gear 25, and the outer wall of the rotating shaft 21 is fixedly connected to the second bevel gear 26, and the first bevel gear 25 and the second bevel gear 26 are meshed. After the motor 24 is started, it drives the first bevel gear 25 to rotate, and the first bevel gear 25 drives the rotating shaft 21 to rotate through the second bevel gear 26, and the rotating shaft 21 drives the mounting bracket 23 to rotate through the connecting base 22, and the mounting bracket 23 drives the monitor 3 to rotate, so that the monitor 3 can rotate during monitoring, thereby continuously adjusting the monitoring angle, thereby expanding the monitoring range.

[0041] Furthermore, the end of the monitor 3 away from the lens is fixedly connected to a sliding shaft 27, and a spring 28 is provided between the sliding shaft 27 and the mounting bracket 23. A protruding rod 29 is fixedly installed on the mounting seat 1, and a waveform ring 210 is fixedly connected to the protruding rod 29. The waveform ring 210 is provided with a wavy contact surface. The sliding shaft 27 is in sliding contact with the wavy contact surface of the waveform ring 210, and the sliding shaft 27 is driven to rotate synchronously when the monitor 3 rotates. The sliding shaft 27 always presses against the wavy contact surface of the waveform ring 210 by the elastic force of the spring 28. The sliding shaft 27 slides along the wavy contact surface during the rotation process, so that the sliding shaft 27 can also move back and forth during the rotation process. When the sliding shaft 27 moves back and forth, it drives the monitor 3 to swing back and forth, so that the monitor 3 can also swing up and down during the rotation process, further expanding the range of monitoring coverage.

[0042] Furthermore, the protective cover 4 is used to protect the monitor 3; the protective cover 4 is fixedly installed at the bottom of the connecting seat 22, and a slot is provided on the protective cover 4. The slot of the protective cover 4 is located below the monitor 3. The protective cover 4 can rotate with the rotation of the connecting seat 22, so that the monitor 3 is always above the slot of the protective cover 4, avoiding the protective cover 4 from blocking the monitor 3, and the protective cover 4 continuously protects the monitor 3.

[0043] In addition, the cleaning component 5 is used to clean the lens of the monitor 3; the cleaning component 5 includes a swivel 51, a column 52, a mounting block 53 and a cleaning cotton 54. The swivel 51 is rotatably mounted on the mounting base 1, the column 52 is fixedly connected to the swivel 51, the mounting block 53 is fixedly connected to the end of the column 52 away from the swivel 51, and the cleaning cotton 54 is mounted on the mounting block 53. The lens of the monitor 3 contacts the cleaning cotton 54 during movement. During the rotation of the monitor 3, the lens of the monitor 3 contacts the cleaning cotton 54, so that the cleaning cotton 54 can use the movement of the lens itself to wipe the lens to maintain the clarity of the lens.

[0044] In addition, the cleaning assembly 5 also includes a cam 55, a pry bar 56, a protrusion 57, a first leaf spring 58, a lever 59, a limiting rod 510, a second leaf spring 511 and a plurality of ratchets 512. The cam 55 is fixedly mounted on the outer wall of the rotating shaft 21, the pry bar 56 is rotatably mounted on the mounting base 1, the protrusion 57 is fixedly connected to the mounting base 1, the first leaf spring 58 is fixedly connected between the protrusion 57 and the pry bar 56, the lever 59 is hinged at the end of the pry bar 56 away from the cam 55, the limiting rod 510 is fixedly connected to the lever 59, the second leaf spring 511 is fixedly connected between the lever 59 and the pry bar 56, and a plurality of ratchets 512 are fixedly connected to the inner wall of the rotating ring 51. During the rotation of the cam 55, the limiting rod 510 is fixedly connected to the lever 59. The second leaf spring 511 is fixedly connected between the lever 59 and the pry bar 56. 56 is in sliding contact with one end away from the shift rod 59, and multiple ratchets 512 are arranged in a circular array. The shift rod 59 is in sliding contact with multiple ratchets 512 in turn during the movement. Every time the cam 55 rotates one circle, it can use the cooperation of the pry bar 56, the shift rod 59 and the multiple ratchets 512 to drive the swivel 51 to rotate a certain angle. When the swivel 51 rotates, the cleaning cotton 54 is driven to rotate synchronously through the column 52 and the mounting block 53, so that the cleaning cotton 54 can be continuously moved. The cleaning cotton 54 can be disassembled and replaced for regular cleaning. The position of the cleaning cotton 54 can be continuously changed to avoid the cleaning cotton 54 staying in the same position for a long time and blocking the monitoring range of the local area for a long time, thereby increasing the range of the monitoring blind spot.

[0045] It is noteworthy that the cleaning assembly 5 further comprises a fluid cylinder 513, an air cylinder 514, an air pipe 515, a liquid pipe 516, a connecting block 517 and an arc block 518. The fluid cylinder 513 is fixedly mounted on the column 52, the air cylinder 514 is fixedly mounted on the outer wall of the fluid cylinder 513, the air pipe 515 is fixedly connected between the fluid cylinder 513 and the air cylinder 514, the liquid pipe 516 is fixedly connected to the fluid cylinder 513, the connecting block 517 is mounted on the monitor 3, the arc block 518 is fixedly connected to the connecting block 517, and the end of the liquid pipe 516 away from the fluid cylinder 513 is connected to the cleaning cotton 54. During the movement, the air cylinder 514 slides in contact with the arc block 518, and the liquid cylinder 513 is filled with detergent. When the lens is about to come into contact with the cleaning cotton 54, the arc block 518 on the connecting block 517 contacts the air cylinder 514 and squeezes the air cylinder 514, so that the air cylinder 514 injects air into the liquid cylinder 513 through the air pipe 515. The liquid cylinder 513 uses positive pressure to inject the detergent into the cleaning cotton 54 through the liquid pipe 516, so that when the cleaning cotton 54 wipes the lens, a small amount of detergent can be attached to the cleaning cotton 54, thereby improving the cleaning effect and further improving the clarity of the lens.

[0046] Example 2

[0047] A method for video monitoring a hazardous chemical warehouse, using the video monitoring device for a hazardous chemical warehouse in Example 1, further comprising the following steps:

[0048] Step 1: Plan and select models, investigate warehouse size, categories, etc., develop a monitoring coverage plan, and select explosion-proof lenses and high-precision sensors to adapt to complex environments.

[0049] Step 2: Hardware installation: Install the mounting base 1 at key locations according to the monitoring coverage plan, connect the industrial-grade wiring to the system, and complete the debugging of the monitor 3.

[0050] Step 3: Software debugging, installing monitoring software, importing map marking devices, setting parameter thresholds and rules, and comprehensively testing system functions.

[0051] Step 4: Intelligent activation, enable AI analysis, identify dangerous behavior alarms, link environmental data, focus on anomalies when exceeding standards, and push information.

[0052] Step 5: Training and establishing rules. Train personnel to be familiar with operations and processing procedures, formulate systems to clarify responsibilities, and standardize the use of the monitoring system.

[0053] Step 6: Maintenance and optimization: regularly maintain and calibrate equipment, collect problems and upgrade the system, analyze data to improve solutions, and enhance monitoring capabilities.

[0054] With the above structure, the working principle of this case is that after the motor 24 is started, it drives the first bevel gear 25 to rotate, the first bevel gear 25 drives the rotating shaft 21 to rotate through the second bevel gear 26, the rotating shaft 21 drives the mounting bracket 23 to rotate through the connecting seat 22, and the mounting bracket 23 drives the monitor 3 to rotate, so that the monitor 3 can rotate during monitoring, thereby continuously adjusting the monitoring angle, thereby expanding the monitoring range, and driving the sliding shaft 27 to rotate synchronously while the monitor 3 rotates. The sliding shaft 27 uses the elastic force of the spring 28 to always press against the wavy contact surface of the wave-shaped ring 210. The sliding shaft 27 slides along the wavy contact surface during the rotation process, so that the sliding shaft 27 can also reciprocate up and down during the rotation process. 7 drives the monitor 3 to swing back and forth when moving back and forth, so that the monitor 3 can also swing up and down during the rotation process, further expanding the scope of monitoring coverage, and the protective cover 4 can rotate along with the rotation of the connecting seat 22, so that the monitor 3 is always above the slot of the protective cover 4, avoiding the protective cover 4 from blocking the monitor 3, and the protective cover 4 continuously protects the monitor 3. Through the setting of the rotating component 2, the monitor 3 can be rotated during monitoring, thereby continuously adjusting the monitoring angle, thereby expanding the monitoring range. Through the cooperation of the sliding shaft 27 and the wave ring 210, the monitor 3 can also swing up and down during the rotation process, further expanding the scope of monitoring coverage and reducing the monitoring blind spot.

[0055] During the rotation of the monitor 3, the lens of the monitor 3 contacts the cleaning cotton 54, so that the cleaning cotton 54 can use the movement of the lens itself to wipe the lens to maintain the clarity of the lens; when the rotating shaft 21 rotates, the cam 55 is driven to rotate. Each rotation of the cam 55 drives the pry bar 56 to swing once. After the pry bar 56 swings, it is reset by the elastic force of the first leaf spring 58. When the pry bar 56 swings, it drives the lever 59 to swing. When the lever 59 swings with the pry bar 56, the lever 59 is The limiting rod 510 is against the pry bar 56, so that the lever 59 cannot rotate on the pry bar 56 at this time. Therefore, the lever 59 can move a ratchet 512 as the pry bar 56 swings, and drives the swivel 51 to rotate a certain angle through the ratchet 512. When the pry bar 56 is reset, the lever 59 is reset accordingly. At this time, the lever 59 contacts another ratchet 512, and the lever 59 is rotated on the pry bar 56 away from the limiting rod 510 by the reverse thrust of the ratchet 512, so that the lever 59 The lever 59 slides over the surface of the ratchet 512 without driving the ratchet 512 to move. After the lever 59 disengages from the ratchet 512, it is reset by the elastic force of the second leaf spring 511. Therefore, every time the cam 55 rotates one circle, the pry bar 56, the lever 59 and the plurality of ratchets 512 can be used to drive the rotating ring 51 to rotate a certain angle. When the rotating ring 51 rotates, the cleaning cotton 54 is driven to rotate synchronously through the column 52 and the mounting block 53, so that the cleaning cotton 54 can be continuously moved. The cleaning cotton 54 can be disassembled and replaced for easy regular cleaning. When the cleaning cotton 54 is continuously moved, the lens of the monitor 3 can still contact with the cleaning cotton 54 during the movement. Through the setting of the cleaning component 5, the cleaning cotton 54 can clean the lens during the rotation of the monitor 3 to maintain the clarity of the lens, and the position of the cleaning cotton 54 can be continuously changed to avoid the cleaning cotton 54 staying in the same position for a long time and blocking the monitoring range of the local area for a long time, thereby increasing the range of the monitoring blind spot.

[0056] The liquid cylinder 513 is filled with a detergent for cleaning the lens. When the monitor 3 rotates, the connecting block 517 is driven to rotate synchronously. When the lens is about to come into contact with the cleaning cotton 54, the arc block 518 on the connecting block 517 contacts the air cylinder 514 and squeezes the air cylinder 514, so that the air cylinder 514 injects air into the liquid cylinder 513 through the air pipe 515. The liquid cylinder 513 uses positive pressure to inject the detergent into the cleaning cotton 54 through the liquid pipe 516. Through the setting of the liquid cylinder 513, when the cleaning cotton 54 wipes the lens, a small amount of detergent can be attached to the cleaning cotton 54, thereby improving the cleaning effect and further improving the clarity of the lens.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
