Description

Technical Field

[0001] This invention relates to the field of security monitoring technology, and in particular to a security monitoring device adapted to low-temperature environments. Background Technology

[0002] Currently, security monitoring devices are often fixed to outdoor poles using mounting brackets, fastening plates, and clamps. The positioning and load-bearing installation of the entire device are mainly achieved by the bolts and nuts between the clamps and the fastening plates.

[0003] In low-temperature winter conditions, the poles, clamps, fastening plates, and connecting fasteners will all experience a contraction effect due to cold. This passively increases the clearance between the components, causing a decrease in the thread engagement accuracy or a reduction in the clamping force of the clamps on the poles. The mounting frame and monitoring equipment are prone to slow vertical descent and slight downward movement, as well as horizontal offset and circumferential rotation. This not only causes deviation in the monitoring and shooting angle but also poses a risk of the monitoring device falling. Summary of the Invention

[0004] The purpose of this invention is to provide a security monitoring device adapted to low-temperature environments, in order to solve the technical problem in the prior art that the cold contraction of the components in winter causes the gaps between the components to increase, the thread engagement and clamping force to weaken, which in turn leads to the monitoring equipment falling, shifting and shaking, affecting the monitoring angle and posing a safety hazard of falling.

[0005] The technical problem to be solved by this invention can be achieved through the following technical solution: A security monitoring device adapted to low-temperature environments includes a monitor. A mounting frame is welded to the bottom of the monitor, and a fastening plate is vertically welded to the end of the mounting frame. Two sets of clamps are provided on the fastening plate and are fitted onto the outer wall of the pole. The clamps and the fastening plate are fixedly connected by nuts. A double reinforcement device is provided between the monitor and the fastening plate to strengthen the monitor's stability.

[0006] Preferably, the dual reinforcement device includes a servo motor fixedly mounted on the top of the mounting frame, the output end of the servo motor is fixedly provided with a drive shaft, both sides of the top of the drive shaft are provided with bidirectional threaded screws that rotate with the mounting frame, and a transmission component for connecting the two is provided between the bidirectional threaded screws and the drive shaft. Among them, the two sets of bidirectional threaded screws are threadedly connected to the outer wall near the upright with threaded sleeves, and the outer wall of the two sets of threaded sleeves is provided with a reinforcement component for reinforcing the connection between the clamp and the fastening plate.

[0007] Preferably, the reinforcing component includes a push plate that slides together with the outer walls of the two sets of threaded sleeves. A positioning ring one is fixedly provided at the end of the threaded sleeve near the upright, and a positioning ring two is fixedly provided on the other outer wall of the threaded sleeve. A limiting post is provided at the top of the positioning ring two that slides together with the outer wall of the push plate. A locking plate one is fixedly installed at each of the four corners of the push plate near the upright. The positioning ring is fitted against the outer wall of the push plate.

[0008] Preferably, the inner wall of the locking plate is provided with an inclined surface, which is in contact with the end of the fastening plate.

[0009] Preferably, a second locking plate is fixedly installed at the end of the first locking plate, and a second inclined surface is provided on the inner wall of the second locking plate near the upright, the second inclined surface being in contact with the outer wall of the upright.

[0010] Preferably, the outer wall of the monitor is provided with a shield, and limit strips are symmetrically installed on the inner wall of the shield opposite to the monitor. The inner wall of the monitor is provided with a sliding groove that slides with the limit strip. The two inner walls at the bottom of the shield are symmetrically provided with moving grooves. The end of the bidirectional threaded screw near the monitor extends into the moving groove, and the end of the bidirectional threaded screw is threaded with the inner wall of the moving groove.

[0011] Preferably, the bottom of the push plate is slidably sleeved above the mounting bracket.

[0012] Preferably, the top of the second locking plate is fitted to the bottom wall of the clamp.

[0013] Preferably, the outer side of the dual-reinforcement device is provided with a protective cover for its protection, and the protective cover is fixedly connected to the mounting bracket.

[0014] One method for using a security monitoring device adapted to low-temperature environments includes the following steps: Step 1: In winter when the temperature is low, control the servo motor to work, which drives the bidirectional threaded screw to rotate through the drive shaft and transmission components, so that the threaded sleeve and the shield move in opposite directions; Step 2: The threaded sleeve moves towards the upright, the first positioning ring disengages from the push plate, and the second positioning ring is limited and drives the push plate to move towards the upright until it is in contact with the pole and continues to advance; Step 3: The push plate moves the locking plate 1 and locking plate 2 closer to the upright. The first inclined surface squeezes the fastening plate and presses down the clamp, while the second inclined surface clamps the upright to form a positioning fulcrum, providing double reinforcement. Simultaneously, the shield moves towards the monitor, extending the shielding area at the monitor's camera lens to block rain and snow with a wrap-around structure.

[0015] The beneficial effects of this invention are: 1. In this invention, a dual reinforcement device is set up. A servo motor drives a bidirectional threaded screw to rotate, which drives the locking plate one and locking plate two of the reinforcement component to simultaneously reinforce the connection between the fastening plate and the upright, and between the clamp and the upright through the squeezing action of inclined plane one and inclined plane two. This effectively compensates for the problem of increased fit clearance and decreased clamping force caused by the low temperature contraction effect in winter, preventing the monitor from falling vertically, shifting horizontally, and swaying circumferentially, avoiding the risk of monitoring angle deviation and device falling. At the same time, locking plate two can provide auxiliary support during clamp installation to prevent clamp slippage, improving installation convenience and efficiency.

[0016] 2. In this invention, when the shield moves toward the monitor, the shield slides against the inner wall of the monitor through the limiting strip, which improves the stability of the limiting strip and the monitor during the sliding process. As the shield moves, the shielding area above the monitor camera is extended. The shield has a wrap-around structure to prevent rain and snow from falling on the lens of the monitor camera in low-temperature environments and affecting the monitoring effect.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1 like Figures 1 to 6 As shown, to address the problem in existing technologies where, in low-temperature winter environments, the gap between the pole 1, clamp 4, and fastening plate 5 increases due to the cold contraction effect, causing a natural decrease in the thread engagement and clamping force of the clamp 4, a security monitoring device adapted to low-temperature environments is proposed. The device includes a monitor 2, a mounting frame 3 welded to the bottom of the monitor 2, and a fastening plate 5 vertically welded to the end of the mounting frame 3. Two sets of clamps 4 are fitted onto the outer wall of the pole 1 on the fastening plate 5, and the clamps 4 and the fastening plate 5 are fixedly connected by nuts. A double reinforcement device is provided between the monitor 2 and the fastening plate 5.

[0021] like Figures 3 to 4 As shown, the dual reinforcement device includes a servo motor 13 fixedly installed on the top of the mounting frame 3. The output end of the servo motor 13 is fixedly provided with a drive shaft 14. Both sides of the top of the drive shaft 14 are provided with bidirectional threaded screws 11 that rotate with the mounting frame 3. The two sets of bidirectional threaded screws 11 are symmetrically arranged with respect to the center line of the mounting frame 3. A transmission component is provided between the bidirectional threaded screws 11 and the drive shaft 14 for connecting the two. Threaded sleeves 17 are threadedly connected to the outer wall of the two sets of bidirectional threaded screws 11 near the upright 1. The outer wall of the two sets of threaded sleeves 17 is provided with reinforcement components for reinforcing the connection between the clamp 4 and the fastening plate 5.

[0022] It should be noted that the transmission component consists of two sets of transmission wheels and one set of transmission belts. One set of transmission wheels is fixedly connected to the outer wall of the drive shaft 14, and the other set of transmission wheels is fixedly connected to the outer wall of the bidirectional threaded screw 11. The two sets of transmission wheels are connected by transmission belts.

[0023] like Figures 3 to 4 As shown, the reinforcement assembly includes a push plate 15 that slides together with the outer walls of the two sets of threaded sleeves 17. A positioning ring 16 is fixedly provided at the end of the threaded sleeve 17 near the upright 1. A positioning ring 19 is fixedly provided on the outer wall of the other side of the threaded sleeve 17. A limiting post 18 that slides together with the outer wall of the push plate 15 is provided at the top of the positioning ring 19. A locking plate 31 is fixedly installed at each of the four corners of the push plate 15 near the upright 1. The positioning ring 16 is in contact with the outer wall of the push plate 15. In the initial position, the two are in contact, which facilitates the subsequent repositioning of the push plate 15.

[0024] like Figures 3 to 6 As shown, a slope 32 is provided on the inner wall of the locking plate 31 opposite to the fastening plate 5, and the slope 32 is in contact with the end of the fastening plate 5.

[0025] like Figures 3 to 6 As shown, a second locking plate 33 is fixedly installed at the end of the first locking plate 31. A second inclined surface 34 is provided on the inner wall of the second locking plate 33 near the upright 1. The second inclined surface 34 is in contact with the outer wall of the upright 1.

[0026] like Figures 3 to 4 As shown, the bottom of the push plate 15 is slidably sleeved above the mounting bracket 3 to ensure the stability of the push plate 15 during operation.

[0027] The working principle in this embodiment is as follows: In the low-temperature environment of winter, the servo motor 13 drives the drive shaft 14 to work. The drive shaft 14 drives two sets of bidirectional threaded screws 11 to rotate through the transmission components. The rotation of the bidirectional threaded screws 11 drives the threaded sleeve 17 and the shield 21 to move away from each other. When the threaded sleeve 17 moves towards the upright 1, the positioning ring 16 no longer fits with the push plate 15, and the positioning ring 19 is limited by the limiting post 18, and moves synchronously towards the upright 1 until the positioning ring 19 fits with the push plate 15, and then pushes a certain distance towards the upright 1. The distance allows the inclined surfaces 32 and 34 of locking plate 31 and locking plate 33 to press synchronously toward one side of the upright 1. This causes the two sets of inclined surfaces 32 to press synchronously against both sides of the fastening plate 5, pressing down on both ends of the clamp 4 and locking the upright 1. The inclined surfaces 34 press synchronously against both sides of the upright 1, forming a double-sided clamping and positioning of the upright 1 through the inclined surfaces 34. This provides a stable force support point for the pressing and limiting of the inclined surfaces 32 of locking plate 31, further strengthening the limiting strength of the inclined surfaces 32 on the ends of the fastening plate 5. This double reinforcement overcomes the problems of increased fit clearance and loosening and sagging caused by low temperature contraction. During seasonal changes and at normal temperature, the bidirectional threaded screw 11 is controlled to rotate in the opposite direction. During the process of resetting the threaded sleeve 17, the positioning ring 16 moves towards the monitor 2 first. The positioning ring 16 drives the push plate 15 to reset, releasing the double reinforcement on both sides of the fastening plate 5. This avoids deformation, stress jamming, and damage to the thread structure caused by the lack of margin for each component under thermal expansion, ensuring that the entire device is adaptable to temperature-changing working conditions all year round. To further illustrate this embodiment: When installing the monitor 2, first attach the fastening plate 5 to the designated outer wall of the pole 1, then insert two clamps 4 in sequence, and install the fastening plate 5 on the pole 1. The bottom of the inserted clamps 4 is attached to the locking plate 2 33. The locking plate 2 33 plays an auxiliary supporting role during the installation of the clamps 4, preventing the clamps 4 from slipping and falling off after being inserted into the fastening plate 5, thus improving the ease of connection between the clamps 4 and the fastening plate 5. The clamps 4 and the fastening plate 5 are then fixed together with nuts, thereby completing the installation of the monitor 2.

[0028] By setting up a double reinforcement device, the servo motor 13 is used to drive the bidirectional threaded rod 11 to rotate, so as to drive the locking plate one 31 and the locking plate two 33 of the reinforcement component to synchronously reinforce the connection between the fastening plate 5 and the vertical rod 1 and the connection between the hoop 4 and the vertical rod 1 through the extrusion of the inclined surface one 32 and the inclined surface two 34. This effectively compensates for the problem of the increased fitting clearance caused by the cold shrinkage effect in winter and the decreased clamping force of the hoop 4, preventing the monitor 2 from vertically dropping, horizontally shifting and circumferentially swaying, and avoiding the risks of the monitoring angle deviation and the device falling. At the same time, the locking plate two 33 can provide auxiliary support during the installation process of the hoop 4 to prevent the hoop 4 from slipping, thus improving the installation convenience and efficiency.

[0029] Embodiment Two As Figures 1 to 4 shown, on the basis of Embodiment One, to solve the problem that in a low-temperature environment, rain, snow and ice are likely to fall on the lens of the monitoring camera, covering the lens and blocking the line of sight, resulting in unclear monitoring and invalid pictures, a shielding cover 21 is provided on the outer wall of the monitor 2. Symmetrically installed on the inner wall of the shielding cover 21 opposite to the monitor ② are limiting strips 22. Sliding grooves that are slidably matched with the limiting strips 22 are provided on the inner wall of the monitor 2. On both sides of the inner wall at the bottom of the shielding cover 21, moving grooves 23 are symmetrically provided. The end of the bidirectional threaded rod 11 close to the monitor 2 extends into the moving groove 23, and the end of the bidirectional threaded rod 11 is in threaded fit with the inner wall of the moving groove 23.

[0030] It should be noted that: the shielding cover 21 has a "冂" - shaped structure to protect the camera lens of the monitor 2 in a wrapping manner.

[0031] As Figure 1 、 Figures 3 to 6 shown, the top of the locking plate two 33 is in contact with the bottom wall of the hoop 4, and the locking plate two 33 supports the fixing plate.

[0032] As Figures 1 to 4 shown, a protective cover 6 for protecting it is provided on the outside of the double reinforcement device, and the protective cover 6 is fixedly connected to the mounting bracket 3. It plays a role in protecting the double reinforcement device.

[0033] The working principle in this embodiment is as follows: when the shielding cover 21 moves towards the monitor 2, the shielding cover 21 improves the stability of the limiting strip 22 during the sliding process with the inner wall of the monitor 2 through the sliding fit of the limiting strip 22 with the inner wall of the monitor 2. And as the shielding cover 21 moves, the shielding area above the camera of the monitor 2 is extended. And referring to Figure 1 - Figure 3 it can be seen that the shielding cover 21 is a wrapping shield, avoiding rain and snow in a low - temperature environment from falling on the lens of the camera of the monitor 2 and affecting the monitoring effect.

[0034] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: Step 1: In winter when the temperature is low, control the servo motor 13 to work, which drives the bidirectional threaded screw 11 to rotate through the drive shaft 14 and transmission components, causing the threaded sleeve 17 and the shield 21 to move in opposite directions.

[0035] Step 2: The threaded sleeve 17 moves toward the upright 1, the positioning ring 16 disengages from the push plate 15, and the positioning ring 19 is limited and drives the push plate 15 to move toward the upright 1 until it is in contact and continues to advance.

[0036] Step 3: Push plate 15 drives locking plate 1 31 and locking plate 2 33 to approach the upright 1. Inclined surface 1 32 squeezes fastening plate 5 and presses down clamp 4. Inclined surface 2 34 clamps upright 1 to form a positioning fulcrum, achieving double reinforcement. Simultaneously, shield 21 moves towards monitor 2, and the movement is stable through limit strip 22.

[0037] Step 4: Extend the covering area of ​​the shield 21 and use a wrap-around structure to block rain and snow to avoid affecting the monitoring effect.

[0038] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
