[0028] Reference Figure 1 to Figure 5The embodiment of the present application provides a black smoke capture device, which may include a base 1, a vertical rod mechanism 2, a cross bar 3, a sleeve 4, a motor seat 5, a drive plate 6, a linear motor 7, a connecting portion 8, a drive box 9, a first drive motor 10, a first drive gear 11, a driven shaft 12, a capture camera 13 and a first driven gear 14, wherein the vertical rod mechanism 2 is arranged on the base 1; the cross bar 3 is arranged on the vertical rod mechanism 2 and is perpendicular to the vertical rod mechanism 2; the sleeve 4 is arranged on the outer periphery of the cross bar 3, and the sleeve 4 has a degree of freedom of movement along the extension direction of the cross bar 3; the motor seat 5 is connected to the cross bar 3; the drive plate 6 is connected to one side of the sleeve 4, and the drive plate 6 is arranged opposite to the motor seat 5 ; The linear motor 7 is connected to the motor seat 5, and the output end of the linear motor 7 is connected to the driving plate 6, and the linear motor 7 provides driving force for the movement of the sleeve 4 on the cross bar 3; one end of the connecting part 8 is connected to the sleeve 4; the driving box 9 is connected to the other end of the connecting part 8; the first driving motor 10 is arranged in the driving box 9, and the output end of the first driving motor 10 extends out of the driving box 9 and rotates with the driving box 9; the first driving gear 11 is fixed to the output end of the first driving motor 10; the driven shaft 12 is rotatably connected to the driving box 9; the snapshot camera 13 is fixed to the end of the driven shaft 12; the first driven gear 14 is arranged on the driven shaft 12, and the first driven gear 14 is meshed with the first driving gear 11.

[0029] Specifically, the black smoke capture device involved in the present application can adjust the position of the capture camera 13 according to actual needs when in use, so as to realize all-round black smoke capture. Specifically, the linear motor 7 drives the slide 4 to move on the crossbar 3, which can drive the drive box 9 and the capture camera 13 to move in the horizontal direction. The output end of the linear motor 7 is connected to the drive plate 6. By controlling the extension and contraction of the linear motor 7, the moving distance of the slide 4 can be accurately controlled, thereby realizing the precise positioning of the capture camera 13 in the horizontal direction. In addition, the first drive gear 11 can be driven to rotate by the first drive motor 10. Since the first drive gear 11 is meshed with the first driven gear 14, the first driven gear 14 will rotate with the rotation of the first drive gear 11, thereby driving the driven shaft 12 and the capture camera 13 to rotate. By controlling the rotation angle and speed of the first drive motor 10, the shooting angle of the capture camera 13 can be accurately adjusted, thereby meeting the black smoke capture requirements at different angles and positions.

[0030] In addition, in order to ensure the stability and reliability of the device, the base 1, the vertical rod mechanism 2, the crossbar 3 and the drive box 9 and other components can be made of high-strength, corrosion-resistant materials to improve the durability and service life of the entire device.

[0031] Reference Figure 2 , Figure 4A dust cover 15 is provided on the outer periphery of the first driving gear 11 and the first driven gear 14 , and the dust cover 15 is rotatably matched with the driven shaft 12 .

[0032] The dust cover 15 can effectively prevent dust and debris from entering the meshing portion between the first drive gear 11 and the first driven gear 14, thereby ensuring the stability and reliability of the gear transmission. The dust cover 15 rotates with the driven shaft 12, so that the dust cover 15 does not interfere with the rotation of the driven shaft 12, and can also maintain a relative position unchanged as the driven shaft 12 rotates.

[0033] Furthermore, the output end of the first drive motor 10 is rotationally matched with the drive box 9 via a bearing; the driven shaft 12 is rotationally connected with the drive box 9 via a bearing; and the dust cover 15 is rotationally matched with the driven shaft 12 via a bearing.

[0034] In this embodiment, the output end of the first drive motor 10 is rotatably matched with the drive box 9 through a bearing, so that the first drive motor 10 can stably drive the first drive gear 11 to rotate without being interfered with by other components; the driven shaft 12 and the drive box 9 are also rotatably connected through a bearing, ensuring that the driven shaft 12 can rotate smoothly, thereby driving the snapshot camera 13 to rotate; at the same time, the dust cover 15 and the driven shaft 12 are also rotatably matched with bearings, which can not only ensure that the dust cover 15 will not hinder the rotation of the driven shaft 12, but also effectively prevent dust and debris from entering the gear meshing part, thereby improving the reliability of the device.

[0035] Reference Figure 2 The vertical rod mechanism 2 may include a vertical plate 201, a horizontal plate 202, a threaded rod 203, an optical axis 204 and a driving mechanism, wherein one end of the vertical plate 201 is connected to the base 1; the horizontal plate 202 is connected to the side of the vertical plate 201 away from the base 1; the threaded rod 203 is rotatably arranged between the horizontal plate 202 and the base 1, and the cross bar 3 is threadedly matched with the threaded rod 203; the optical axis 204 is fixed between the horizontal plate 202 and the base 1, and the optical axis 204 is slidably matched with the cross bar 3; the driving mechanism is arranged in the base 1, and the output end of the driving mechanism is connected to the input end of the threaded rod 203.

[0036] Among them, when it is necessary to adjust the height of the capture camera 13, it can be achieved by driving the threaded rod 203 to rotate through the driving mechanism. Since the cross bar 3 is threadedly matched with the threaded rod 203, the cross bar 3 will be lifted and lowered along the axis direction of the threaded rod 203. At the same time, the setting of the optical axis 204 ensures the stability of the cross bar 3 during the lifting process, and prevents the cross bar 3 from shaking or tilting. By accurately controlling the output of the driving mechanism, the precise control of the lifting position of the cross bar 3 can be achieved, thereby meeting the precise adjustment requirements for the height of the capture camera 13.

[0037] Reference Figure 5 The driving mechanism may include a second driving motor 16, a second driving gear 17 and a second driven gear 18, wherein the second driving motor 16 is fixed in the base 1; the second driving gear 17 is fixed to the output end of the second driving motor 16; the second driven gear 18 is fixed to the input end of the threaded rod 203, and the second driven gear 18 is meshed with the second driving gear 17.

[0038] Specifically, by controlling the rotation of the second drive motor 16, the second drive gear 17 can be driven to rotate, and then the second driven gear 18 can be driven to rotate through the meshing relationship. Since the second driven gear 18 is fixedly connected to the input end of the threaded rod 203, the threaded rod 203 will rotate with the rotation of the second driven gear 18, thereby adjusting the lifting position of the cross bar 3. This driving method has a simple structure, is easy to control, and can achieve precise lifting position adjustment, meeting the height adjustment requirements of the black smoke capture device.

[0039] Furthermore, the diameter of the second driving gear 17 is a, the diameter of the second driven gear 18 is b, a<b; the diameter of the first driving gear 11 is c, the diameter of the first driven gear 14 is d, c<d.

[0040] Among them, in order to enable the second drive motor 16 to drive the threaded rod 203 to rotate with a smaller torque and achieve a larger lifting range, a second driven gear 18 with a larger diameter is used. In this way, when the second drive motor 16 rotates, the second drive gear 17 will drive the second driven gear 18 to rotate at a lower speed, but because the diameter of the second driven gear 18 is larger, it can drive the threaded rod 203 to perform a larger range of lifting and lowering movements. Similarly, in order to enable the first drive motor 10 to drive the capture camera 13 to rotate with a smaller torque and achieve a larger rotation angle, a first driven gear 14 with a larger diameter is used. This design makes the black smoke capture device more stable and reliable during movement, while also reducing the requirements for the drive motor and improving the economy and practicality of the device.

[0041] Reference Figure 2 A first bearing seat 19 is provided on the side of the base 1 facing the horizontal plate 202, and a first bearing 20 is provided in the first bearing seat 19; a second bearing seat 21 is provided on the side of the horizontal plate 202 away from the base 1, and a second bearing 22 is provided in the second bearing seat 21; wherein, both ends of the threaded rod 203 are respectively matched with the first bearing 20 and the second bearing 22.

[0042] In this embodiment, the first bearing seat 19 and the first bearing 20 are used between the base 1 and the horizontal plate 202 to support and rotate one end of the threaded rod 203, ensuring that the threaded rod 203 can rotate stably; at the same time, the other side of the horizontal plate 202 supports and rotates the other end of the threaded rod 203 through the second bearing seat 21 and the second bearing 22, further improving the rotation stability of the threaded rod 203. This design not only makes the structure of the entire vertical rod mechanism 2 more compact and stable, but also ensures the stability and reliability of the cross bar 3 during the lifting process, providing a good working platform for the black smoke capture device.

[0043] Reference Figure 2 , Figure 3 The sliding sleeve 4 may include a first ring 401 and a second ring 402 , wherein the first ring 401 is slidably matched with the cross bar 3 ; the second ring 402 is slidably matched with the cross bar 3 and there is a gap between the second ring 402 and the first ring 401 .

[0044] In this embodiment, the sliding sleeve 4 is provided with a first ring 401 and a second ring 402, so as to achieve clamping and sliding fit of the cross bar 3. The first ring 401 and the second ring 402 are respectively located on both sides of the cross bar 3 and form a sliding fit relationship with the cross bar 3, so that the sliding sleeve 4 can move along the axis direction of the cross bar 3. At the same time, there is a certain gap between the first ring 401 and the second ring 402, so as to reduce the friction between the sliding sleeve 4 and the cross bar 3, so that the sliding sleeve 4 slides on the cross bar 3 more smoothly.

[0045] Reference Figure 2 , Figure 3 The connecting part 8 may include a first connecting column 801 and a second connecting column 802, wherein one end of the first connecting column 801 is connected to the first ring 401, and the other end is connected to the drive box 9; one end of the second connecting column 802 is connected to the second ring 402, and the other end is connected to the drive box 9.

[0046] Among them, the sliding sleeve 4 can be connected to the driving box 9 through the first connecting column 801 and the second connecting column 802, so that the driving box 9 can drive the sliding sleeve 4 to move along the crossbar 3. At the same time, the design of the first connecting column 801 and the second connecting column 802 also enhances the connection stability between the sliding sleeve 4 and the driving box 9, preventing the sliding sleeve 4 from shaking or falling off during the movement. This structural design not only ensures the stability and reliability of the movement of the sliding sleeve 4, but also makes the structure of the entire black smoke capture device more compact and reasonable.

[0047] Reference Figure 2 , Figure 3 Two vertical plates 23 are arranged between the horizontal plate 202 and the base 1 , and the threaded rod 203 and the optical axis 204 are located between the two vertical plates 23 .

[0048] In this embodiment, the provision of the two vertical plates 23 not only enhances the connection strength between the horizontal plate 202 and the base 1, making the entire vertical rod mechanism 2 more stable; but also provides good support and positioning for the threaded rod 203 and the optical axis 204, ensuring their stability and accuracy during movement.
