DETAILED DESCRIPTION

[0034] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0035] like Figures 1 to 6As shown, this embodiment proposes an anti-collision monitoring camera, including a protective tube 1 and a camera body 2 arranged at the bottom of the protective tube 1, a shielding mechanism 5 is arranged at the top of the protective tube 1, and a storage mechanism 3 is arranged inside the protective tube 1, which can shrink the camera body 2 when the shielding mechanism 5 is hit by an external object. The storage mechanism 3 includes a lifting component arranged inside the protective tube 1, a guide component 4 arranged between the camera body 2 and the inner wall of the protective tube 1, and a limiting mechanism 6 arranged between the lifting component and the shielding mechanism 5. The bottom of the protective tube 1 is also provided with a blocking mechanism 7 that can seal the bottom of the protective tube 1 after the camera body 2 is stored inside the protective tube 1;

[0036] The surrounding environment can be monitored by the camera body 2 arranged under the protective tube 1. It should be noted that a battery for powering the camera body 2 is also arranged inside the protective tube 1, so that the camera body 2 can perform normal shooting. When a falling object hits the monitoring equipment, the protective tube 1 can shield the camera body 2 thereunder, and the falling object will first contact the shielding mechanism 5. Therefore, the shielding mechanism 5 can protect the protective tube 1, thereby further improving the protection effect of the camera body 2. At the same time, when the shielding mechanism 5 is hit by the falling object, When struck, the storage mechanism 3 will be opened through the limiting mechanism 6, and the storage mechanism 3 will pull the camera body 2 back into the protective tube 1 to prevent the camera body 2 from being exposed to foreign objects and being damaged when falling objects from high altitude fall. After the camera body 2 is pulled back into the protective tube 1, the sealing mechanism 7 provided can also seal the bottom of the protective tube 1 to form a closed space inside the protective tube 1 to prevent any debris from entering the protective tube 1 to damage the camera body 2 and affect the monitoring work, thereby being able to provide all-round protection for the camera body 2 and prolong the service life of the camera body 2.

[0037] Specifically, Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the shielding mechanism 5 includes a support tube 501 arranged at the top of the protective tube 1, a slide column 502 slidably arranged inside the support tube 501, a buffer spring 503 arranged between the bottom of the slide column 502 and the inner bottom wall of the support tube 501, a support plate 504 arranged at the top of the slide column 502, and baffles 505 arranged at both sides of the support plate 504 and inclined, a mounting groove is opened on the surface of the baffle 505, and a plurality of rubber balls 506 are rotatably arranged on the surface of the mounting groove;

[0038] The support plate 504 and the baffle plate 505 arranged on the top of the protective tube 1 can shield and protect the protective tube 1 and the camera body 2 below it. When a falling object hits the support plate 504 or the baffle plate 505, the support plate 504 is compressed and drives the slide column 502 to slide toward the inside of the support tube 501. At this time, the buffer spring 503 can buffer and reduce the shock of the slide column 502 and the support plate 504 and the baffle plate 505 on its top to prevent the support plate 504 and the baffle plate 505 from being damaged. Because the baffle 505 is arranged at an angle, the falling objects can slide down quickly and avoid being accumulated on the top of the baffle 505. Because a plurality of rubber balls 506 are arranged on the surface of the baffle 505, when the falling objects come into contact with the rubber balls 506, the rubber balls 506 are elastic, which can not only provide buffering protection for the baffle 505, but also the rubber balls 506 can roll due to friction when hit by foreign objects, thereby making the falling objects roll down quickly, further improving the protection effect of the baffle 505, the protective tube 1 and the camera body 2.

[0039] like Figure 5 , Figure 6 , Figure 7 , Fig. 9 and Fig.11 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the pulling component includes a partition 101 arranged on the inner wall of the protective tube 1, a rotating column 301 rotatably arranged on the inner walls of both sides of the protective tube 1 and extending outward, a reel 302 arranged between the two rotating columns 301, a torsion spring 303 arranged on the rod wall of the rotating column 301 between the reel 302 and the inner wall of the protective tube 1, and a pull rope 304 arranged between the reel 302 and the camera body 2;

[0040] The guide component 4 includes a guide plate 401 disposed on the top of the camera body 2 and slidably connected to the inner wall of the protective tube 1, an iron frame 403 disposed on the inner wall of the protective tube 1 near the bottom, and a magnet 402 disposed at the bottom of the guide plate 401;

[0041] The limiting mechanism 6 comprises a moving seat 601 symmetrically slidably arranged on both sides of the top of the protective tube 1, a push rod 602 movably arranged at the bottom of the moving seat 601 and the support plate 504, a curved rod 603 arranged on the side wall of the moving seat 601, and a limiting block 604 arranged at one end of the curved rod 603 away from the moving seat 601, and a limiting groove 3011 matching with the limiting block 604 is formed at the end of the rotating column 301 located outside the protective tube 1;

[0042] When the falling object hits the support plate 504 or the baffle plate 505, the support plate 504 that is pressed downward will push the moving seat 601 to slide toward the top of the protective tube 1 on both sides through the push rod 602 at its bottom, and the moving seat 601 will drive the curved rod 603 to move horizontally, thereby driving the limit block 604 to disengage from the limit groove 3011 at the end of the rotating column 301. At this time, the torsion spring 303 is released from the force, which will drive the rotating column 301 and the reel 302 to rotate and reel up the pull rope 304, so that the camera body can be moved. 2 is pulled back into the protective tube 1 for protection. When the camera body 2 needs to be used again, the camera body 2 can be pulled downward, and the camera body 2 will slide down vertically along the inner wall of the protective tube 1 through the guide plate 401. When the camera body 2 is pulled out of the protective tube 1, the magnet 402 at the bottom of the baffle 505 is just attracted to the iron frame 403, and the position of the camera body 2 can be fixed. Therefore, when the camera body 2 is pulled down, the reel 302 and the rotating column 301 will be driven to rotate through the pull rope 304. Therefore, the torsion spring 303 will have a force to drive the rotating column 301 and the reel 302 to reverse and reset. However, at this time, the support plate 504 is not affected by the impact of the falling object, so the buffer spring 503 will drive the support plate 504 to move upward and reset, and the moving seat 601 will also be pulled toward the middle of the protective tube 1 to reset, so that the limit block 604 on the curved rod 603 is inserted into the limit groove 3011 at the end of the rotating column 301 again, and the rotating column 301 and the reel 302 can be limited again. , preventing the torsion spring 303 from driving the rotating column 301 and the scroll 302 to rotate. It should be noted that the shape of the limit block 604 and the limit groove 3011 can be set to a square, so when the square structure limit block 604 is inserted into the square structure limit groove 3011, it is convenient to stably fix the rotating column 301, and a sliding groove that cooperates with the moving seat 601 can be set on the top of the protective tube 1, so that the moving seat 601 can be squeezed by the push rod 602 and can slide stably on the top of the protective tube 1.

[0043] like Figure 2 , Figure 3 , Figure 4 and Fig.10 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, the blocking mechanism 7 further includes a rotating shaft 701 rotatably arranged on both sides of the bottom of the protective tube 1 and extending outward, a sealing plate 702 sleeved on the outside of the rotating shaft 701, a spring 703 arranged on the rod wall of the rotating shaft 701, and a transmission component 8 arranged outside the protective tube 1 and capable of driving the rotating shaft 701 to rotate when the camera body 2 moves vertically;

[0044] The transmission component 8 includes a rotating rod 801 rotatably arranged on the outer wall of the protective tube 1 through a fixed block, an active bevel gear 802 arranged on the rod walls on both sides of the rotating rod 801, a driven bevel gear 803 rotatably arranged on the outer wall of the protective tube 1 and meshing with the active bevel gear 802, a pulley 804 arranged between the end of the driven bevel gear 803 and the end of the rotating shaft 701 located on the outside of the protective tube 1, and a rotating assembly arranged between the camera body 2 and the rotating rod 801;

[0045] The rotating assembly includes a toothed plate 805 slidably arranged on the side wall of the protective tube 1, a gear 808 arranged on the rod wall of the rotating rod 801, a pressure plate 806 arranged at one end of the toothed plate 805 located inside the protective tube 1, a push plate 807 arranged on the top of the camera body 2 and matched with the pressure plate 806, and an elastic reset member arranged on the top of the toothed plate 805, wherein the elastic reset member is a compression spring 9;

[0046] Under normal conditions, the spring 703 will drive the rotating shaft 701 to rotate, causing the sealing plate 702 to flip toward both sides of the protective tube 1 to open the opening at the bottom of the protective tube 1, making it easier for the camera body 2 to enter and exit. When the device is hit by a falling object and the camera body 2 is pulled into the protective tube 1 through the pull rope 304, the push plate 807 on the top of the protective tube 1 will drive the toothed plate 805 with the pressure plate 806 to move upward, and the toothed plate 805 will drive the rotating rod 801 with the gear 808 to rotate. The rotating rod 801 then drives the pulley 804 to rotate through the active bevel gear 802 and the driven bevel gear 803, thereby driving the rotating shaft 701 to rotate and driving the sealing plate 702 to flip toward the middle of the protective tube 1, blocking the opening at the bottom of the protective tube 1, making the protective tube 1 completely sealed, thereby preventing debris from entering the protective tube 1 through the bottom opening and damaging the camera body 2, thereby increasing the service life of the camera body 2.

[0047] In addition, a protective frame 10 for shielding the transmission component 8 is provided on the back of the protective tube 1, a support frame 11 is provided on the side wall of the protective frame 10, and a connecting flange is provided at the end of the support frame 11; the protective frame 10 can be used to shield the components in the transmission component 8 to prevent foreign objects from touching the transmission component 8 and affecting the normal operation of the blocking mechanism 7; in addition, the protective tube 1 can be installed at a suitable position that needs to be monitored by using the connecting flange provided on the support frame 11 and the bolts.

[0048] The working principle of the present invention is as follows: when a falling object hits the support plate 504 or the baffle plate 505, the support plate 504 is compressed and drives the slide column 502 to slide toward the inside of the support tube 501. At this time, the buffer spring 503 can buffer and reduce the shock of the slide column 502 and the support plate 504 and the baffle plate 505 on the top thereof to prevent the support plate 504 and the baffle plate 505 from being damaged. Moreover, when the falling object contacts the baffle plate 505, because the baffle plate 505 is inclined, the falling object can be quickly The falling objects can slide down quickly to prevent them from accumulating on the top of the baffle 505. Because a number of rubber balls 506 are arranged on the surface of the baffle 505, when the falling objects come into contact with the rubber balls 506, the rubber balls 506 are elastic, which can not only provide buffering protection for the baffle 505, but also the rubber balls 506 can roll due to friction when hit by foreign objects, so that the falling objects can roll down quickly, thereby further improving the protection effect of the baffle 505, the protective tube 1 and the camera body 2.

[0049] At the same time, the support plate 504 that is pressed and moved downward will push the moving seat 601 to slide toward the two sides of the top of the protective tube 1 through the push rod 602 at its bottom. The moving seat 601 will drive the curved rod 603 to move horizontally, and then drive the limit block 604 to disengage from the limit groove 3011 at the end of the rotating column 301. At this time, the torsion spring 303 is released from the force and will drive the rotating column 301 and the reel 302 to rotate and reel up the pull rope 304, so that the camera body 2 can be pulled back into the protective tube 1 for protection.

[0050] When the device is hit by falling objects and the camera body 2 is pulled into the protective tube 1 through the pull rope 304, the push plate 807 on the top of the protective tube 1 will drive the tooth plate 805 with the pressure plate 806 to move upward, and the tooth plate 805 will drive the rotating rod 801 with the gear 808 to rotate. The rotating rod 801 then drives the pulley 804 to rotate through the active bevel gear 802 and the driven bevel gear 803, thereby driving the rotating shaft 701 to rotate and driving the sealing plate 702 to flip toward the middle of the protective tube 1, blocking the opening at the bottom of the protective tube 1, making the protective tube 1 completely sealed, thereby preventing debris from entering the protective tube 1 through the bottom opening and damaging the camera body 2, thereby increasing the service life of the camera body 2.

[0051] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
