Description

Technical Field

[0001] This utility model belongs to the field of camera bracket technology, specifically a portable maintenance bracket for tunnel cameras. Background Technology

[0002] A camera is a device that converts optical image signals into electrical signals. When an object is photographed, the light reflected from the object is collected by the camera lens and focused onto the light-receiving surface of the imaging device. Through photoelectric conversion, the light is converted into an electrical signal, generating a "video signal." Because photoelectric signals are very weak, they need to be amplified by a pre-amplifier circuit and processed and adjusted by subsequent circuits to finally form a standard signal. These signals can be sent to storage devices such as video recorders for recording, transmitted through a transmission system, or directly output to a monitor for display. The entire process achieves efficient conversion and processing from optical images to electrical signals.

[0003] Currently, various methods have been proposed for portable maintenance brackets for tunnel cameras in existing technologies. For example, a patent application with publication number "CN218327146U" discloses a camera bracket including a storage box. Rollers are movably installed near the four corners of the front and rear ends of the storage box. A movable door is movably installed at the top of the storage box, and a support column is fixedly installed above the door. A telescopic column passes through the upper end of the support column, and a support plate is fixedly installed at the top of the telescopic column. Clamping mechanisms are provided near both sides of the upper end of the support plate. A camera is positioned above the support plate. Bolts pass through the outside of the support column near the top, with one end of the bolt fitting against the outside of the telescopic column. Thus, when raising or lowering the telescopic column, only loosening the bolts is needed to complete the extension or reduction of the telescopic column. However, for brackets located inside tunnels, the low humidity and lack of sunlight make the bolts prone to rusting. Rusty bolts are difficult to loosen, causing significant inconvenience to maintenance work. Maintenance personnel need to spend more time and effort to loosen the bolts, which not only reduces maintenance efficiency but also delays maintenance time and affects the normal operation of the tunnel monitoring system.

[0004] Therefore, this utility model provides a portable maintenance bracket for tunnel cameras. Utility Model Content

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The portable maintenance bracket for a tunnel camera described in this utility model allows the forward and reverse movement of the central gear to be controlled by stepping on the pedals on both sides. The forward and reverse movement of the central gear can drive the worm gear to rotate in both directions, thereby moving the nut up or down through the screw. This allows the camera to be moved down for maintenance, and then the camera can be moved up to reset. The screw and nut are always kept in a sealed protective cylinder, avoiding the rusting problem of traditional bolts caused by humidity and lack of sunlight in the tunnel environment. This reduces the difficulty for maintenance personnel to loosen the bolts and improves maintenance efficiency.

The portable maintenance bracket for a tunnel camera described in this utility model provides a protective cylinder at the upper end of the mechanism box, allowing the screw to rotate within the protective cylinder. The protective cylinder protects the screw, preventing dust, particles, and other impurities from falling onto it and preventing the screw and nut from getting stuck due to impurities, which could affect the lifting function.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 4 As shown in the embodiment of this utility model, a portable maintenance bracket for a tunnel camera includes a mechanism box 1. A rotating rod 22 is rotatably connected to the inner wall of the mechanism box 1, and a worm gear 14 is fixedly connected to the rotating rod 22. A screw 16 is rotatably connected to the bottom of the mechanism box 1, and a worm wheel 15 is fixedly connected to the screw 16. The worm wheel 15 meshes with the worm gear 14. A first driving gear 12 is rotatably connected to the inner wall of the mechanism box 1. The first driving gear 12 is connected to a first driven gear 13 via a clockwise one-way bearing 23. A second driving gear 20 is rotatably connected to the inner wall of the mechanism box 1. The second driving gear 20 is connected to a second driven gear 13 via a counterclockwise one-way bearing 24. 8. It should be noted that the function of the clockwise one-way bearing 23 is that the first driving gear 12 can drive the first driven gear 13 to rotate only when the first driving gear 12 rotates clockwise, and the counterclockwise rotation of the first driven gear 13 will not drive the first driving gear 12 to rotate through the clockwise one-way bearing 23. The function of the counterclockwise one-way bearing 24 is that the second driving gear 20 can drive the second driven gear 18 to rotate only when the second driving gear 20 rotates counterclockwise, and the second driven gear 18 cannot drive the second driving gear 20 to rotate in the opposite direction through the counterclockwise one-way bearing 24 when it rotates clockwise. A first rack 11 and a second rack 19 are slidably connected inside the mechanism housing 1. The first rack 11 meshes with a first drive gear 12, and the second rack 19 meshes with a second drive gear 20. A drive mechanism for driving the second rack 19 and the first rack 11 is installed on the sidewalls of the mechanism housing 1. A guide mechanism for guiding the second rack 19 and the first rack 11 is installed inside the mechanism housing 1.

[0026] like Figure 1As shown, a maintenance box 8 is provided on the upper end of the mechanism box 1. A nut 17 is threaded onto the screw 16, and two fixing rods 9 are fixedly connected to the upper end of the nut 17. A tray 27 is fixedly connected to the upper end of the fixing rods 9, and a camera 10 is mounted on the upper end of the tray 27. Through the above structure, the maintenance box 8 provides a dedicated storage space for storing tools, spare parts, and other maintenance equipment. This design allows maintenance personnel to quickly find the required tools, reducing the time spent searching for tools and thus improving maintenance efficiency. In addition, the maintenance box 8 can also protect tools and equipment from the influence of the external environment, extending the service life of the tools.

[0027] like Figure 1 As shown, the side wall of the mechanism box 1 is provided with four fixing plates 3. With the above structure, bolts and other fixing parts can be used to fix the mechanism box 1 more firmly to the tunnel wall or other supporting structure, thereby enhancing the overall stability of the support.

[0028] like Figures 1 to 3 As shown, the drive mechanism includes two connecting rods 5 and two pedals 6. Each connecting rod 5 is fixedly mounted on the side wall of an adjacent second rack 19 and first rack 11, and each pedal 6 is fixedly mounted on a connecting rod 5. During operation, the forward and reverse movement of the intermediate gear 21 can be controlled by stepping on the left and right pedals 6. The forward and reverse movement of the intermediate gear 21 can drive the worm wheel 15 to rotate forward and reverse via the worm gear 14, thereby causing the nut 17 to move up or down via the screw 16. Through this structure, the design of the pedals 6 and connecting rods 5 allows the operator to control the raising and lowering of the camera 10 with a simple stepping action, without the need for complex tools or equipment. This design not only improves the convenience of operation but also reduces the reliance on specialized tools, making maintenance work more efficient.

[0029] like Figure 1 As shown, the side wall of the mechanism housing 1 has two sliding grooves 4, and the connecting rod 5 slides within adjacent sliding grooves 4. During operation, the connecting rod 5 slides freely within the sliding grooves 4, while the side wall of the sliding groove 4 limits its movement. Through this structure, the sliding grooves 4 provide a stable sliding path for the connecting rod 5, ensuring that the connecting rod 5 will not shake or get stuck during movement.

[0030] like Figure 3 and 4As shown, the guiding mechanism includes two sleeves 28, two slides 25, and two springs 26. Each sleeve 28 is fixedly installed at the inner bottom end of the mechanism housing 1. One end of each slide 25 is fixedly installed at the lower end of an adjacent second rack 19 and first rack 11, and the other end of the slide 25 slides within the sleeve 28. One end of each spring 26 is fixedly installed at the inner bottom end of the sleeve 28, and the other end of the spring 26 is fixedly installed at the lower end of the slide 25. During operation, stepping on the pedal 6 causes the slide 25 to move downwards, compressing the spring 26. When the worker's foot is removed from the upper end of the pedal 6, the compressed spring 26 returns to its original position, causing the slide 25 to move upwards automatically.

[0031] like Figure 1 As shown, a caster wheel 7 is installed at the lower end of the mechanism box 1. Through this structure, the caster wheel 7 allows the support to move easily within the tunnel, adapting to different working position requirements and improving the portability and flexibility of the equipment.

[0032] like Figure 1 As shown, a protective cylinder 2 is fixedly connected to the upper end of the mechanism box 1. The screw 16 rotates inside the protective cylinder 2, and the screw 16 passes through the rotating mechanism box 1. The fixing rod 9 passes through the sliding protective cylinder 2. Through the above structure, the protective cylinder 2 provides a closed protective environment for the screw 16, preventing dust, particles, and other impurities in the tunnel from falling on the screw and avoiding jamming and wear caused by impurities. Furthermore, the fixing rod 9 passes through the sliding protective cylinder 2, so that the side wall of the contact point where the protective cylinder 2 and the fixing rod 9 slide through limits the fixing rod 9, thereby allowing the support plate 27 to move only up and down.

[0033] Working principle: When maintenance is required on 10, such as... Figure 1 As shown, by stepping on the right pedal 6, the drive connecting rod 5 drives the first rack 11 to move downward. The first rack 11 meshes with the first drive gear 12, causing the first drive gear 12 to rotate clockwise. The first drive gear 12 drives the first driven gear 13 to rotate clockwise through the clockwise one-way bearing 23. The first driven gear 13 drives the intermediate gear 21 to rotate counterclockwise, which in turn drives the worm gear 14 to rotate through the rotating rod 22. The worm gear 14 drives the worm wheel 15 to rotate, and the worm wheel 15 drives the screw 16 to rotate, thereby causing the nut 17 to move downward, achieving the purpose of moving the camera 10 downward.

[0034] When the camera 10 needs to be moved upwards and reset after maintenance, stepping on the left pedal 6 causes the second rack 19 to move downwards via the connecting rod 5. The second rack 19 then drives the second drive gear 20 to rotate counterclockwise. The second drive gear 20, through the counterclockwise one-way bearing 24, drives the second driven gear 18 to rotate counterclockwise. The second driven gear 18 then drives the intermediate gear 21 to rotate clockwise. This causes the intermediate gear 21 to drive the worm gear 14 to rotate via the rotating rod 22. Consequently, the worm gear 14 drives the worm wheel 15 to rotate, and the worm wheel 15 drives the screw 16 to rotate. At this time, the rotation direction of the screw 16 is opposite to the rotation direction when stepping on the right pedal 6, thus moving the nut 17 upwards and achieving the purpose of moving the camera 10 upwards and resetting it.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
