Description

Technical Field

[0001] This invention relates to the field of camera equipment installation and commissioning, specifically a space pre-occupancy and protection device for the installation of a television surveillance camera. Background Technology

[0002] CCTV equipment is an indispensable part of the daily management of public places and is widely installed and used in construction projects. During its installation and construction, the installation and commissioning phases are independent and do not overlap in time. The installers are construction workers, while the commissioning personnel are on-site technicians. The difference in their professional skills and job responsibilities often leads to the installation phase overlooking surrounding obstacles and failing to accurately assess whether the reserved space is sufficient, resulting in insufficient space. During commissioning, the cameras need to rotate significantly horizontally and vertically. However, in situations where there are objects nearby, obstacles can still obstruct the cameras during commissioning, preventing the CCTV cameras from achieving their intended commissioning purpose. Summary of the Invention

[0003] The purpose of this invention is to provide a space reservation and protection device for the installation of television surveillance cameras. When installing a camera, this device is used to protect the camera and check whether sufficient space has been reserved to prevent damage to the camera.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A space occupancy and protection device for installing a television surveillance camera includes a protection mechanism and a clamping mechanism for detachable and fixed installation with the camera. The protection mechanism includes a fixed frame fixed to the clamping mechanism. The fixed frame has an annular bracket fixed to it on its outer side away from the clamping mechanism. An air source is connected to the annular bracket. An inflatable bladder is fixed on the annular bracket. The inflatable bladder can expand to the outside of the camera when inflated by the air source.

[0006] Preferably, the inflatable bladder includes a main rigid airbag and a skirt airbag. The main rigid airbag is hemispherical and is fixed to the periphery of the annular bracket and arches away from the clamping mechanism. A secondary rigid airbag is connected to the arched surface of the main rigid airbag. The periphery of the skirt airbag is fixed to the side of the annular bracket near the clamping mechanism. The skirt airbag is provided with a window for the camera to pass through, and a retractable elastic edge is fixed to the window.

[0007] Furthermore, a first pressure sensor is provided on the top of the main rigid airbag, and a second pressure sensor is provided on the top of the auxiliary rigid airbag.

[0008] Preferably, the air source is a small air pump installed in the fixed frame. A four-way pipe is connected to the air outlet of the small air pump. A pressure relief pipe with a pressure relief valve is connected to one air passage interface of the four-way pipe. Two branch pipes are connected to the remaining two air passage interfaces of the four-way pipe respectively. An air valve is provided in the branch pipe. The end of the branch pipe away from the four-way pipe is connected and fixed to the annular bracket.

[0009] Preferably, the fixing frame is provided with an extension rod fixedly connected thereto, and the outer end of the extension rod is fixedly connected to the annular bracket.

[0010] Preferably, the clamping mechanism includes a slide plate, a positioning plate, and a clamping plate. The fixing frame is fixed on the slide plate, the top of the positioning plate is fixedly installed relative to the slide plate, the clamping plate is arranged opposite to the positioning plate, and the clamping plate has a linear travel along the length direction of the slide plate.

[0011] Preferably, rubber pads are fixed to the lower parts of the opposite sides of the positioning plate and the clamping plate.

[0012] Furthermore, a threaded rod is rotatably connected to the top of the positioning plate. The threaded rod is aligned with the length direction of the slide plate. A threaded sleeve that is threadedly engaged with the threaded rod is fitted onto the threaded rod. The threaded sleeve is fixed to the clamping plate. A slide frame is fixedly connected to the top of the clamping plate. The slide plate passes through the slide frame and the two slide in a sliding engagement.

[0013] Furthermore, the threaded rod has a handle at one end away from the clamping plate, and a limit plate is fixed at the other end of the threaded rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This invention can clamp and position the camera body, meeting the fixation requirements of the protection mechanism. It also facilitates quick assembly and disassembly of the protection mechanism by installers. The expansion of the airbag creates a shape change, effectively protecting the camera body and camera module area. After installation, the inflated airbag significantly expands in front of the camera, pre-occupying the space needed for camera rotation. As long as the inflated airbag does not interfere with surrounding facilities, rotation required for later maintenance and future application can be guaranteed. Once it is confirmed that obstacles in the surrounding area will not cause interference, the protection mechanism can be removed.

[0016] Therefore, by installing this device and inflating the airbag, one can directly observe whether obstacles around the installation site will interfere with the normal use of the camera body. This allows for sufficient space to be simulated during installation, enabling free rotation during the debugging phase. The device can be used during installation and then removed for use on the next camera. Using a small number of these devices can meet the installation needs of all cameras, leaving ample space for later debugging. Attached Figure Description

[0032] Example: A space occupancy and protection device for installing a television surveillance camera

[0033] It is mainly used to provide protection for general-purpose television surveillance cameras during the commissioning phase.

[0034] The development of this technology stems from the problem of repetitive disassembly and assembly, or camera damage during the debugging phase, in engineering projects. Through summarizing our findings, we discovered that many projects require the installation of numerous cameras, but installation and debugging are separate processes. Initial installation is typically done by construction workers, whose technical skills are limited. In most cases, they cannot adequately estimate the operating space for the cameras and easily overlook nearby obstacles, simply placing them in roughly the correct position. After completion, factory technicians come to debug the cameras. They find that many cameras are surrounded by obstacles such as cable trays and ducts, which the cameras will bump into when rotating, leaving insufficient space for movement. Therefore, reserving sufficient space during installation is crucial. However, the installers are construction workers with limited technical skills and judgment, thus requiring the use of this device.

[0035] refer to Figure 1-5 As shown, the main structure of this protection device mainly includes a clamping mechanism and a protection mechanism;

[0036] For ease of introduction, this device will be described in conjunction with a camera. The main structure of the camera includes a camera body 1. An adjustment head 2 that can adjust its angle is installed at the bottom of the camera body 1. An L-shaped mounting bracket 3 is provided at the bottom of the adjustment head 2. This device is not limited to this example and can also be used with cameras of other structures.

[0037] 1) Clamping mechanism 4

[0038] The clamping mechanism 4 includes a positioning plate 41, which is used to clamp one side of the camera body 1. A threaded rod 42 is rotatably connected to the top of the positioning plate 41. A handle 43 is fixedly connected to one end of the threaded rod 42, and a limiting plate is fixed to the other end of the threaded rod 42. A threaded sleeve 44 is fitted onto the threaded rod 42 and is threadedly engaged with it. The limiting plate is used to engage with the threaded sleeve 44 to prevent the threaded rod 42 from moving beyond its travel range and falling off. A clamping plate 45 is fixedly connected to the outside of the threaded sleeve 44. The clamping plate 45 is arranged parallel to the positioning plate 41 and is used to clamp and fix the camera body 1 on both sides.

[0039] The top of the clamping plate 45 is fixedly connected to a slide 46, and the top of the positioning plate 41 is fixedly connected to a slide plate 47. The slide plate 47 is a long strip-shaped component. The slide plate 47 is located above the threaded rod 42 and the two extend in the same direction and side by side. The slide plate 47 passes through the slide 46 and the two slide in a sliding fit. The end of the slide plate 47 away from the positioning plate 41 is fixedly connected to a limit head. Through the sliding fit between the slide plate 47 and the slide 46, the linear travel of the clamping plate 45 is auxiliaryly constrained, making the clamping plate 45 more stable when it moves closer to or further away from the positioning plate 41.

[0040] Based on the above structure, by rotating the threaded rod 42, under the linear sliding constraint of the slide plate 47 and the carriage 46, the clamping plate 45 can be moved closer to or away from the positioning plate 41, thereby clamping and fixing both sides of the camera body 1.

[0041] To protect the camera body's outer casing, rubber pads are fixed to the lower parts of the opposite sides of the positioning plate 41 and the clamping plate 45. Based on the anti-slip and flexible properties of the rubber pads, the clamping effect is enhanced, and the camera is protected, preventing the positioning plate 41 and the clamping plate 45 from clamping too tightly and causing damage to the clamping surface of the camera body 1.

[0042] The clamping mechanism 4 clamps and positions the camera body 1, which meets the fixing requirements of the protection mechanism for the camera body 1, provides stable support for the protection mechanism, and also facilitates quick assembly and disassembly of the protection mechanism by the installers.

[0043] 2) Protection Agency 7

[0044] The protection mechanism includes a fixing frame 5, which is fixedly installed in the middle of the slide plate 47 to support and fix the entire protection mechanism.

[0045] The mounting bracket 5 is provided with an extension rod 8 fixedly connected thereto. One end of the extension rod 8 is fixed to the mounting bracket 5, and the end of the extension rod 8 away from the mounting bracket 5 is fixed with a ring bracket 6. The extension rod 8 is used to enable the ring bracket 6 to be located at the lens part of the camera and to protect the lens part.

[0046] The mounting bracket 5 is a shell structure. A small air pump 75 and a four-way pipe 76 are installed inside the mounting bracket 5. The four-way pipe 76 includes four interfaces, which are defined as the first interface, the second interface, the third interface, and the fourth interface for ease of description. The outlet of the small air pump is fixedly connected to the first interface. A pressure relief pipe 78 is connected to the second interface of the four-way pipe 76, and a pressure relief valve is installed on the pressure relief pipe 78. The third and fourth interfaces are located on the left and right sides of the four-way pipe 76, respectively, and are connected to branch pipes 77. The branch pipes 77 are fixed to the mounting bracket 5. There are two branch pipes 77 arranged symmetrically on the left and right sides for more stable auxiliary support. The branch pipes 77 are connected to the small air pump 75 through the four-way pipe 76, thereby enabling the supply and connection of the air source. A solenoid valve is installed inside the branch pipe 77, and the branch pipe 77 is made of metal tubing, allowing for automatic control of the opening and closing of the branch pipe 77. The end of the branch pipe 77 furthest from the four-way pipe 76 is fixed to the annular bracket 6 and connected to the main rigid airbag 71, enabling the supply and connection of the air source. Furthermore, the pressure relief valve ensures that the connected air source remains within a safe pressure range. When the internal gas pressure of the main rigid airbag 71 and the auxiliary rigid airbag 73 is too high, it plays the role of venting and depressurizing.

[0047] The annular bracket 6 has a main rigid airbag 71 fixed along its annular surface. The main rigid airbag 71 is fixed to the inner wall of the annular bracket 6, and a first pressure sensor 72 is provided on the top of the main rigid airbag 71. The main rigid airbag 71 is an outwardly arched spherical airbag. A secondary rigid airbag 73 is connected to the arched surface of the main rigid airbag 71. A second pressure sensor 74 is provided on the top of the secondary rigid airbag 73. The cross-sectional areas of the main rigid airbag 71 and the secondary rigid airbag 73 after inflation are larger than the cross-sectional areas of the camera body 1 and the camera assembly, respectively, so that the main rigid airbag 71 and the secondary rigid airbag 73 maintain the optimal protection range with the camera body 1 and the camera assembly, and avoid the main rigid airbag 71 and the secondary rigid airbag 73 being too large or too small and causing collisions with the camera body 1 and the camera assembly.

[0048] The annular bracket 6 is fixed with a skirt airbag 79 on the side near the clamping mechanism 4. The skirt airbag 79 is connected to the main rigid airbag 71 to form a complete airbag protection, which effectively protects the area of ​​the main rigid airbag 71 near the camera body 1, so as to achieve the purpose of comprehensive protection of the camera components.

[0049] The portion of the annular support 6 located within the main rigid airbag 71 and the skirt airbag 79 is provided with an air outlet for inflating the entire inflatable bladder body composed of the main rigid airbag 71, the secondary rigid airbag 73, and the skirt airbag 79.

[0050] The skirt-shaped airbag 79 has a centrally located window for the camera body 1 to pass through. An elastic edge 791 is sewn along the edge of the window, ensuring close contact with the side wall of the camera body. This enhances the overall seal between the skirt-shaped airbag 79 and the camera body 1, while also meeting the sealing requirements of camera bodies 1 of different sizes. The elastic edge 791 can be a drawstring tightening structure for manual tightening, or it can be a rubber band-assisted closing structure.

[0051] By setting up a protection mechanism 7, the first pressure sensor 72 and the second pressure sensor 74 monitor the pressure of the main rigid airbag 71 and the auxiliary rigid airbag 73 in real time. A small air pump 75 provides the air source. Through the cooperation of the main rigid airbag 71, the auxiliary rigid airbag 73, the four-way pipe 76, the branch pipe 77 and the pressure relief pipe 78, the shape change generated by the inflation of the airbags is used to expand and pre-occupy the space of the camera body 1 and the camera component area, and to check whether the obstacles around the installation site will interfere with the normal use of the camera body 1 in the later stage.

[0052] The working principle of this device is as follows: When the installer finds obstacles in the surrounding area during the installation of the camera body 1 with the help of the adjusting head 2 and the L-shaped mounting bracket 3, the installer first places the main rigid airbag 71, the auxiliary rigid airbag 73 and the skirt airbag 79 in the predetermined position of the camera body 1, and then positions the positioning plate 41 in a suitable position on the camera body 1. Then, the threaded rod 42 is adjusted to make the clamping plate 45 close to the positioning plate 41, thereby fixing the camera body 1 and completing the installation of this device relative to the camera body 1.

[0053] After installation, the installer starts the small air pump 75 and supplies air into the four-way pipe 76. At this time, two sets of solenoid valves open, and the gas then passes through two branch pipes 77 to the main rigid airbag 71 and the auxiliary rigid airbag 73 in sequence. Simultaneously, the first pressure sensor 72 and the second pressure sensor 74 monitor the gas pressure in the main rigid airbag 71 and the auxiliary rigid airbag 73 in real time. The annular bracket 6 provides fixed support, so as the gas gradually enters, the main rigid airbag 71 and the auxiliary rigid airbag 73 expand. At the same time, the gas in the main rigid airbag 71 also enters the skirt airbag 79, and the skirt airbag 79 expands as well, until the main rigid airbag 71, the auxiliary rigid airbag 73, and the skirt airbag 79 expand to... When the camera reaches its optimal configuration, the small air pump 75 stops supplying air. At this time, the two sets of solenoid valves close synchronously. The expanded main rigid airbag 71, secondary rigid airbag 73, and skirt airbag 79 effectively protect the camera body 1 and the camera assembly. The elastic edge 791 then seals the skirt airbag 79 and the camera body 1. When the first pressure sensor 72 and the second pressure sensor 74 detect that the gas pressure inside the main rigid airbag 71 and secondary rigid airbag 73 is too high, the pressure relief valve opens, and the excess gas is discharged through the pressure relief pipe 78 until the gas pressure inside the main rigid airbag 71 and secondary rigid airbag 73 is maintained at the optimal state. Even when there are obstacles in the surrounding area, this system can still meet the installation and debugging needs of the installers for the camera body 1.

[0054] After inspecting the surrounding space, the gas in the main rigid airbag 71 and the auxiliary rigid airbag 73 is completely discharged through the pressure relief pipe 78. Then, the main rigid airbag 71, the auxiliary rigid airbag 73 and the skirt airbag 79 retract and reset. Then, grip the handle 43 to drive the threaded rod 42 to rotate counterclockwise, so that the clamping plate 45 is away from the clamping surface of the camera body 1. The ring bracket 6 can then be disassembled for installation and use by other cameras.

[0055] The advantage of this example is:

[0056] 1. By setting up a clamping structure, the camera body is clamped and positioned by the cooperation of the positioning plate, threaded rod, swivel handle, threaded sleeve and clamping plate, which meets the fixing requirements of the protection mechanism for the camera body and provides stable support for the protection mechanism. At the same time, it is also convenient for installers to quickly disassemble and assemble the protection mechanism. By setting up the protection mechanism, the first pressure sensor and the second pressure sensor monitor the pressure of the main rigid airbag and the auxiliary rigid airbag in real time. Then, a small air pump provides the air source. Through the cooperation of the main rigid airbag, the auxiliary rigid airbag, the four-way pipe, the branch pipe and the pressure relief pipe, the shape change generated by the inflation of the airbag can be used to simulate the space required for the camera body to rotate horizontally and vertically in all directions. Check whether the obstacles around the installation site will interfere with the normal use of the camera body in the later stage.

[0057] 2. The slide and slide plate improve the stability of the clamping plate during its movement and provide auxiliary limiting for its sliding. The protective rubber pad enhances the protection of the inner side of the positioning plate and clamping plate, preventing damage to the clamping surface of the camera body caused by excessive clamping. The limiting plate prevents the threaded rod from falling out due to exceeding its travel range and effectively limits its movement.

[0058] 3. The skirt-shaped airbag effectively protects the area of ​​the main rigid airbag near the camera body, achieving comprehensive protection for the camera components. The adjustable end enhances the overall seal between the skirt-shaped airbag and the camera body, while also meeting the sealing requirements of camera bodies of different sizes. An electromagnetic valve is installed inside the branch pipe, and the branch pipe itself is made of metal, automatically controlling its opening and closing. This also enhances the strength of the branch pipe material, providing auxiliary support for the main rigid airbag. A pressure relief valve releases pressure when the internal gas pressure of the main and auxiliary rigid airbags becomes excessive. The cross-sectional areas of the main and auxiliary rigid airbags are larger than those of the camera body and camera components, respectively, maintaining optimal protection between the main and auxiliary rigid airbags and the camera body and components, preventing collisions caused by excessively large or small airbags.
