A high-altitude monitoring device and method for construction sites

Abstract

This invention discloses a high-altitude monitoring device and method for construction sites, comprising a mounting column, a fixing frame fixedly connected to the surface of the mounting column, and a mounting shell rotatably connected to the surface of the fixing frame. During operation, the invention utilizes a protective shell, elastic telescopic plates, and shock-absorbing springs to protect the mounting shell and camera lens, reducing the impact of the protective shell on the fixing frame. This prevents the fixing frame from loosening or being damaged by large objects or strong impacts. In rainy weather, rainwater flows into a collection box. When the water in the collection box reaches a certain weight, the collection box moves downwards along with a protective eave. The eave and collection box block the channels and fences on both sides of the protective shell, preventing rainwater from entering the interior of the protective shell through the channels, thus keeping the working area of ​​the mounting shell and camera lens dry.

Description

Technical Field

[0001] This invention relates to the field of high-altitude monitoring devices, specifically a high-altitude monitoring device and method for construction sites. Background Technology

[0002] A construction site is a place where buildings are constructed. During daily construction, there is a large turnover of workers, and safety protection measures are generally not perfect. The working environment is also quite complex, and accidents are inevitable during construction. It is difficult for people to understand the process of the accident, which makes it difficult to deal with. There may also be cases such as theft of steel materials from the construction site, resulting in the loss of building materials and affecting the normal use of the construction site. Therefore, surveillance cameras are installed on construction sites.

[0003] Current technology typically involves installing surveillance cameras at high altitudes within construction sites. These cameras are usually mounted on the surface of the building's external scaffolding or tower crane support. During construction, debris inevitably flies or falls from heights. Falling debris hitting the surveillance cameras can cause them to shift or become damaged, preventing them from providing stable monitoring of the construction site. Furthermore, surveillance cameras at high altitudes are susceptible to weather conditions, resulting in unclear images. Additionally, damaged cameras require manual access to high altitudes for repair or replacement, which can easily lead to accidents. Summary of the Invention

[0004] The purpose of this invention is to provide a high-altitude monitoring device and method for construction sites to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-altitude monitoring device for construction sites, comprising a mounting column, a fixed frame fixedly connected to the surface of the mounting column, a mounting shell rotatably connected to the surface of the fixed frame, a camera lens fixedly connected inside the mounting shell, a protective mechanism provided on the surface of the fixed frame for protecting the camera lens, a shock-absorbing mechanism provided between the protective mechanism and the fixed frame for reducing the impact of the protective mechanism on the fixed frame, retraction mechanisms provided on both sides of the protective mechanism for retracting when the mounting shell rotates, and shielding mechanisms provided on both sides of the protective mechanism for automatically shielding both sides of the mounting shell in rainy weather;

[0006] As a further embodiment of the present invention, the protective mechanism includes a protective shell, which is disposed on the surface of the fixed frame through the shock absorption mechanism. The protective shell has an opening on one side corresponding to the camera lens, and a soft, arc-shaped protective top is fixedly connected to the upper end of the protective shell.

[0007] As a further embodiment of the present invention, the shock-absorbing mechanism includes a through-hole, which is opened on the surface of the protective shell near the fixed frame. The fixed frame is located inside the through-hole. An elastic telescopic plate is connected between the bottom of the inner wall of the through-hole and the bottom surface of the fixed frame. A shock-absorbing spring is connected between the top of the inner wall of the through-hole and the surface of the fixed frame. A push plate is fixedly connected to the surface of the fixed frame. The upper end of the push plate passes through the protective shell and extends to the arc-shaped protective top position. A U-shaped blocking plate is fixedly connected to the inner wall of the protective shell.

[0008] As a further embodiment of the present invention, the shrinking mechanism includes multiple sets of through slots, which are respectively opened on both sides of the protective shell. Each set of through slots is elastically slidably connected to a fence plate. A fixing plate is fixedly connected to the fence plate on the side of the mounting shell. Both sides of the mounting shell are fixedly connected to elastically telescopic actuating plates, which extend to the surface of the fixing plate.

[0009] As a further embodiment of the present invention, the shielding mechanism includes two retractable shielding eaves, which are respectively fixedly connected to the two side surfaces of the arc-shaped protective top. The shielding eaves are arc-shaped and located at positions corresponding to the fence panels. Collection boxes are fixedly connected to both sides of the arc-shaped protective top. The side of the collection box closest to the protective shell is an elastically retractable plate, and the collection box is teardrop-shaped. The collection box is located at the rear side of the shielding eaves corresponding to the through groove position. The collection box fits against the shielding eaves, and the shielding eaves communicate with the collection box.

[0010] As a further embodiment of the present invention, a fixing ring is fixedly connected to the surface of the mounting shell, and a support plate is fixedly connected to the upper end of the fixing ring. A first sliding plate and a second sliding plate are slidably connected to the surface of the support plate near the camera lens. A U-shaped wiping frame is fixedly connected to the surface of both the first and second sliding plates. A wiping cotton is fixedly connected to the surface of the wiping frame near the camera lens. A first pull rope is fixedly connected to the surface of the first sliding plate. Fixing posts are fixedly connected to both sides of the support plate and the surface of the mounting shell. The first pull rope extends to the collection box after passing around the fixing post near the first sliding plate. The first pull rope passes through the protective shell and is connected to the collection box. The first pull rope is elastic. A second pull rope is fixedly connected to the surface of the second sliding plate. The second pull rope extends to the middle of the side wall of the protective shell after passing around the fixing post near the second sliding plate. A sliding block is connected to the end of the second pull rope after passing through the protective shell. The sliding block is located below the collection box and slides on the surface of the protective shell.

[0011] As a further embodiment of the present invention, grooves are provided on both sides of the mounting shell, and reflectors are elastically provided in both grooves. The two reflectors extend to the position of the fixing ring on the side near the fixing ring, and the two reflectors are slidably connected to both sides of the fixing ring. A third pull rope is fixedly connected to the surface of each of the two reflectors. Two fixing rods are fixedly connected to the surface of the mounting shell. The two third pull ropes pass around the fixing rods and are respectively connected to the surface of the first sliding plate and the second sliding plate. The third pull rope near the first sliding plate is connected to the second sliding plate, and the third pull rope near the second sliding plate is connected to the first sliding plate.

[0012] A method for using a high-altitude monitoring device at a construction site, the specific steps of which are as follows:

[0013] Step 1: Install high-altitude monitoring devices on the surface of the external scaffolding or tower crane support frame at the construction site;

[0014] Step 2: After installation, the camera lens will be protected.

[0015] Step 3: The shock absorption mechanism can reduce the impact of debris hitting the protective mechanism on the fixed frame;

[0016] Step 4: The retraction mechanism will retract as the mounting housing rotates;

[0017] Step 5: The shielding mechanism will automatically shield both sides of the mounting housing during rainy weather.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. During the operation of the monitoring device, this invention utilizes a protective shell, elastic telescopic plate, and shock-absorbing springs to protect the mounting shell and camera lens, reducing the impact of the protective shell on the mounting bracket. This prevents the mounting bracket from loosening or being damaged by large objects or strong impacts, which could affect the stable shooting of the camera lens. In rainy weather, rainwater flows into the collection box. When the water in the collection box reaches a certain weight, the collection box and the shielding eaves move downwards together. The shielding eaves and the collection box block the channels and grid plates on both sides of the protective shell, preventing rainwater from entering the interior of the protective shell through the channels. This helps keep the working area of ​​the mounting shell and camera lens dry, preventing rainwater from flowing along the surface of the protective shell into the interior, which could damage the camera lens, prevent it from shooting, and affect normal monitoring.

[0020] 2. When monitoring in rainy weather, when the weight of the water in the collection box reaches a certain level, the collection boxes on both sides will move sequentially with the first and second pull ropes. The first and second pull ropes will then move the first and second sliding plates, respectively. The first and second sliding plates will then move the wiping frame and wiping cotton downwards together. The wiping cotton will wipe half of the camera lens surface at a time, which helps to keep the camera lens surface clean and prevents rainwater from adhering to the camera lens surface, thus affecting the normal monitoring and shooting of the camera lens. Furthermore, the first and second sliding plates move alternately, dividing the camera lens into two parts for wiping, reducing the obstruction of the camera lens's shooting image during wiping, and preventing the camera lens from being blocked during wiping, which would affect the camera lens's shooting.

[0021] 3. During monitoring in rainy weather, when the collection box moves the first sliding plate downwards, the first sliding plate moves the third pulling rope. The third pulling rope passes around the fixed rod and pulls the reflector on the side closest to the second sliding plate. The reflector slides within the groove. As the reflector moves, the end of the reflector closest to the camera lens gradually tilts upwards under the action of the fixed ring. After the reflector is fully extended, the camera lens can capture the image obscured by the wiping cotton through the reflection of the reflector. When the second sliding plate moves downwards, it can move the reflector on the other side out. This is beneficial for compensating for the obstructed image when the camera lens is blocked, preventing the camera from failing to capture a complete monitoring image when the lens is blocked, thus ensuring real-time recording in case of an accident.

[0034] Please see Figures 1-10 The present invention provides a technical solution: a high-altitude monitoring device for construction sites, including a mounting column 1, a fixing frame 2 fixedly connected to the surface of the mounting column 1, a mounting shell 3 rotatably connected to the surface of the fixing frame 2, a camera lens 4 fixedly connected inside the mounting shell 3, a protective mechanism provided on the surface of the fixing frame 2 for protecting the camera lens 4, a shock-absorbing mechanism provided between the protective mechanism and the fixing frame 2 for reducing the impact of the protective mechanism on the fixing frame 2, a retraction mechanism provided on both sides of the protective mechanism for retracting when the mounting shell 3 rotates, and a shielding mechanism provided on both sides of the protective mechanism for automatically shielding both sides of the mounting shell 3 in rainy weather;

[0035] The protective mechanism includes a protective shell 5, which is mounted on the surface of the fixed frame 2 via a shock-absorbing mechanism. The protective shell 5 has an opening on one side corresponding to the camera lens 4, and a soft, arc-shaped protective top 6 is fixedly connected to the upper end of the protective shell 5.

[0036] The shock absorption mechanism includes a through-hole 7, which is opened on the surface of the protective shell 5 near the fixed frame 2. The fixed frame 2 is located inside the through-hole 7. An elastic telescopic plate 8 is connected between the bottom of the inner wall of the through-hole 7 and the bottom surface of the fixed frame 2. A shock-absorbing spring 9 is connected between the top of the inner wall of the through-hole 7 and the surface of the fixed frame 2. A push plate 10 is fixedly connected to the surface of the fixed frame 2. The upper end of the push plate 10 passes through the protective shell 5 and extends to the arc-shaped protective top 6. A U-shaped baffle plate 11 is fixedly connected to the inner wall of the protective shell 5.

[0037] The retraction mechanism includes multiple sets of through slots 12, which are respectively opened on both sides of the protective shell 5. Each set of through slots 12 is elastically slidably connected to a fence plate 13. A fixing plate 14 is fixedly connected to the side of the fence plate 13 closest to the mounting shell 3. Both sides of the mounting shell 3 are fixedly connected to elastically telescopic actuating plates 15, which extend to the surface of the fixing plate 14.

[0038] The shielding mechanism includes two retractable shielding eaves 16, which are fixedly connected to the two sides of the arc-shaped protective top 6. The shielding eaves 16 are arc-shaped and located at the corresponding positions of the fence panels 13. Collection boxes 17 are fixedly connected to both sides of the arc-shaped protective top 6. The side of the collection box 17 closest to the protective shell 5 is an elastically retractable plate, and the collection box 17 is teardrop-shaped. The collection box 17 is located at the position of the through groove 12 on the rear side of the shielding eaves 16. The collection box 17 fits into the shielding eaves 16, and the shielding eaves 16 and the collection box 17 are connected.

[0039] When the high-altitude monitoring device is installed on the surface of the mounting column 1 at a high altitude, if debris falls on the surface of the curved protective top 6 and the protective shell 5, the protective shell 5 will block the debris, preventing it from directly hitting the mounting shell 3 and causing the camera lens 4 to shift, shake, or become damaged, thus affecting the monitoring effect. After the protective shell 5 is hit, it will shake up and down under the action of the elastic telescopic plate 8 and the shock-absorbing spring 9 to reduce the impact force. The fixing frame 2 will slide within the opening 7, which helps to reduce the impact of the mounting shell 3 on the fixing frame 2. This prevents the mounting shell 3 from directly impacting the fixing frame 2 when the debris is large or the impact force is large, which could cause the fixing frame 2 to loosen or be damaged, affecting the stable shooting of the camera lens 4. When debris hits the protective shell 5... When the impact force is large, the protective shell 5 will shake significantly. The baffle plate 11 will contact the fixing frame 2 to block the protective shell 5, preventing it from hitting the mounting shell 3 and causing it to shake, thus affecting the normal monitoring and recording of the camera lens 4. When debris hits the surface of the arc-shaped protective top 6, some debris will remain on the surface. When the protective shell 5 shakes, the agitator plate 10 will move the arc-shaped protective top 6 up and down, which helps to dislodge the debris remaining on the surface of the arc-shaped protective top 6 and remove it from the top of the protective shell 5. This prevents debris from accumulating on the surface of the arc-shaped protective top 6, which would affect the shock absorption effect and hinder the buffering of subsequent debris impacts. During monitoring, it is necessary to... When adjusting the monitoring angle, the mounting shell 3 and the camera lens 4 will rotate to one side. The mounting shell 3 will drive the actuating plate 15 to rotate together. The actuating plate 15, in the direction of rotation, will cause the fixing plate 14 to move closer to the fixing frame 2. The fixing plate 14 will then drive the fence plate 13 to move closer to the fixing frame 2. The fence plate 13 will slide within the through groove 12, which helps to reduce the obstruction of the camera lens 4's image by the fence plate 13. This prevents the protective shell 5 from extending directly to both sides of the camera lens 4. When the mounting shell 3 rotates, the protective shell 5 will obstruct the image captured by the camera lens 4, affecting the normal monitoring and recording of the camera lens 4. The through groove 12 can also provide ventilation and heat dissipation. In rainy weather, rainwater will flow along the surface of the arc-shaped protective top 6. The water flows to the shielding eaves 16 and collection box 17 on both sides. The water in the shielding eaves 16 also flows to the collection box 17. When the water in the collection box 17 reaches a certain weight, the collection box 17 will move downward together with the shielding eaves 16. The shielding eaves 16 and collection box 17 will block the through grooves 12 and the fence 13 on both sides of the protective shell 5, preventing rainwater from entering the interior of the protective shell 5 through the through grooves 12. This helps to keep the working area of ​​the mounting shell 3 and the camera lens 4 dry, and prevents rainwater from flowing along the surface of the protective shell 5 into the interior of the protective shell 5, which could damage the camera lens 4, prevent it from shooting, and affect normal monitoring. In addition, the teardrop-shaped collection box 17 can reduce secondary collisions when debris leaves the top of the protective shell 5.

[0040] During monitoring in rainy weather, raindrops will fall onto the surface of the camera lens 4. As a further embodiment of the present invention, a fixing ring 18 is fixedly connected to the surface of the mounting shell 3, and a support plate 19 is fixedly connected to the upper end of the fixing ring 18. A first sliding plate 20 and a second sliding plate 21 are slidably connected to the surface of the support plate 19 near the camera lens 4. A U-shaped wiping frame 22 is fixedly connected to the surface of both the first sliding plate 20 and the second sliding plate 21. A wiping cotton 23 is fixedly connected to the surface of the wiping frame 22 near the camera lens 4. A first pulling rope 24 is fixedly connected to the surface of the first sliding plate 20. Fixing posts 25 are fixedly connected to both sides of the support plate 19 and the surface of the mounting shell 3. The first pull rope 24 extends to the collection box 17 after passing around the fixed post 25 near the first sliding plate 20. The first pull rope 24 passes through the protective shell 5 and is connected to the collection box 17. The first pull rope 24 is elastic. A second pull rope 26 is fixedly connected to the surface of the second sliding plate 21. The second pull rope 26 passes around the fixed post 25 near the second sliding plate 21 and extends to the middle of the side wall of the protective shell 5. The end of the second pull rope 26 passes through the protective shell 5 and is connected to a sliding block 27. The sliding block 27 is located below the collection box 17 and slides on the surface of the protective shell 5. During monitoring in rainy weather, when the weight of the water in the collection box 17 reaches a certain level, both sides... The collection box 17 will move downwards together. The collection box 17 near the first sliding plate 20 will pull the first pulling rope 24 to move together. The first pulling rope 24 will go around the fixed post 25 and pull the first sliding plate 20 downwards. The first sliding plate 20 will drive the wiping frame 22 and wiping cotton 23 to move downwards together. The wiping cotton 23 will wipe the half of the mirror surface of the camera lens 4 near the first sliding plate 20. Then the wiping frame 22 will pass over the camera lens 4. After the collection box 17 near the second sliding plate 21 moves downwards a certain distance, it will drive the sliding block 27 to move downwards together. The sliding block 27 will drive the second pulling rope 26 to move downwards together. The second pulling rope 26 will go around the fixed post 25. Then, the second sliding plate 21 moves downward, which in turn moves the wiping frame 22 and wiping cotton 23 near the second sliding plate 21 downward. The wiping cotton 23 near the second sliding plate 21 wipes the half of the mirror surface of the camera lens 4 that is close to the second sliding plate 21, which helps to keep the surface of the camera lens 4 clean and prevents rainwater from adhering to the surface of the camera lens 4, thus affecting the normal monitoring and shooting of the camera lens 4. Furthermore, the first sliding plate 20 and the second sliding plate 21 move alternately, dividing the camera lens 4 into two parts for wiping, reducing the obstruction of the camera lens 4's shooting image during wiping, and preventing the camera lens 4 from being blocked during wiping, thus affecting the shooting of the camera lens 4.

[0041] When wiping the camera lens 4, the wiping cotton 23 still partially obstructs the image captured by the camera lens 4. As a further solution of the present invention, grooves 28 are provided on both sides of the mounting shell 3, and reflectors 29 are elastically provided in both grooves 28. The two reflectors 29 extend to the position of the fixing ring 18 on the side near the fixing ring 18, and the two reflectors 29 are slidably connected to both sides of the fixing ring 18. A third pull rope 30 is fixedly connected to the surface of the two reflectors 29. Two fixing rods 31 are fixedly connected to the surface of the mounting shell 3. The two third pull ropes 30 pass around the fixing rods 31 and are respectively connected to the surface of the first sliding plate 20 and the second sliding plate 21. The third pull rope 30 near the first sliding plate 20 is connected to the second sliding plate 21, and the third pull rope 30 near the second sliding plate 21 is connected to the first sliding plate 20. During monitoring in rainy weather, when the collection box 17 When the first sliding plate 20 moves downward, it will move the third pulling rope 30 together. The third pulling rope 30 will go around the fixed rod 31 and pull the reflector 29 on the side near the second sliding plate 21. The reflector 29 will slide in the slide groove 28. During the movement of the reflector 29, the end of the reflector 29 near the camera lens 4 will gradually tilt up under the action of the fixed ring 18. After the reflector 29 is fully extended, the camera lens 4 can capture the image blocked by the wiping cotton 23 through the reflection of the reflector 29. When the second sliding plate 21 moves downward, it can move the reflector 29 on the other side. This is beneficial to use the reflector 29 to compensate for the blocked image of the camera lens 4 when the image captured by the camera lens 4 is blocked. This avoids the camera lens 4 not being able to capture the monitoring image completely when it is blocked, so that real-time recording can be carried out in the event of an accident.
