Description

Technical Field

[0001] This utility model relates to the technical field of protective devices for monitoring equipment, specifically an external protective device for monitoring equipment. Background Technology

[0002] To ensure the safety and proper operation of surveillance equipment, protective devices are typically required. These devices are encased in a robust housing, providing additional protection for the surveillance equipment. The protective housing also ensures the quality of the images detected by the surveillance equipment and provides a better working environment.

[0003] According to a public notice (Announcement No.: CN220732913U) regarding a protective device for surveillance equipment, the aforementioned application provides comprehensive protection for the surveillance equipment by incorporating a mounting base, connecting arm, and protective shell. This effectively protects the equipment from external impacts and harsh environments. Simultaneously, the optimized buffer device and damping rod effectively reduce the transmission of external vibrations to the surveillance equipment, improving its stability and making the camera work more stably, thus providing clearer images. The inclusion of a fan, air inlet, and ventilation opening effectively enhances the heat dissipation performance of the surveillance equipment, reducing its temperature and extending its service life. Furthermore, water-shielding plates are installed at both ends of the protective shell, which, together with sealing rings, prevent rainwater from entering the interior of the protective shell. The inclusion of a disassembly door and lock facilitates disassembly, installation, and maintenance while preventing unauthorized individuals from opening the disassembly door and damaging the surveillance equipment.

[0004] However, in actual use, the aforementioned devices cannot provide comprehensive protection for the monitoring equipment inside the protective shell and the lens under relatively extreme conditions. When the lens of the monitoring equipment is contaminated by the external environment, the stains cannot be actively cleaned. The presence of stains will seriously affect the imaging quality of the monitoring, making it impossible for the camera to provide high-definition image quality. In view of this, we propose an external protective device for monitoring equipment. Utility Model Content

[0023] like Figures 1-4As shown, this utility model provides a technical solution: an external protective device for monitoring equipment, including a mounting plate 1, a support arm 11 fixedly connected to one end of the mounting plate 1, and a cleaning mechanism 2 provided at the end of the support arm 11 away from the mounting plate 1. The cleaning mechanism 2 includes: a mounting frame 21, a protective shell 22, an observation window 23, a top cover 24, a water tank 25, a motor 26, a connecting shaft 27, a connecting rod 28, a scraper 29, a nozzle 210, a sliding groove 211, a ventilation groove 212, and a push rod 213.

[0024] In one embodiment of this utility model, the bottom surface of the mounting bracket 21 is fixedly connected to the end of the support arm 11 away from the mounting plate 1. A protective shell 22 is fixedly connected to the upper surface of the mounting bracket 21. An observation window 23 is provided on the outer surface of the protective shell 22. A top cover 24 is snapped onto the upper surface of the protective shell 22. The bottom surface of the top cover 24 is fixedly connected to the outer wall of the water tank 25. A motor 26 is fixedly connected to the inner wall of the water tank 25. The bottom surface of the connecting shaft 27 is fixedly connected to the outer wall of the output end of the motor 26. A connecting rod 28 is fixedly connected to the outer surface of the connecting shaft 27. A scraper 29 is fixedly connected to the bottom surface of the connecting rod 28. A nozzle 210 is fixedly connected to the side wall of the scraper 29. A sliding groove 211 is provided on the upper surface of the protective shell 22. Ventilation slots 212 are provided on the outer surface of the protective shell 22. A push rod 213 is fixedly connected to the side wall of the connecting rod 28. There are two sets of connecting rods 28, which are distributed symmetrically in mirror image on the outer wall of the connecting shaft 27. A through groove is provided on the inner wall of the connecting shaft 27, and the other end of the through groove is connected to the nozzle 210. The output end of the motor 26 is T-shaped, and the input end of the water tank 25 is located on the outer surface of the protective shell 22. The output end of the water tank 25 is cylindrical and fixedly connected to the inner wall of the connecting shaft 27. The protective shell 22 is spherical in shape, and the end of the scraper 29 near the protective shell 22 abuts against the outer surface of the protective shell 22. A silicone plate is fixedly connected to the end of the scraper 29 near the protective shell 22. The motor 26 drives the connecting shaft 27 to rotate, which in turn enables the connecting rod 28 to drive the scraper 29 to periodically clean the outer surfaces of the protective shell 22 and the observation window 23. This maintains the continuous cleanliness of the observation window 23, which is beneficial for the monitoring equipment 41 to capture clear and stable video recordings. Furthermore, by setting the number of connecting rods 28 to two sets, the scraper 29 has better stability when rotating around the connecting shaft 27. Simultaneously, the water tank 25 allows cleaning fluid added to the tank to flow into the nozzle 210 through a channel when stubborn stains appear. The cleaning fluid is then output through the nozzle 210 onto the outer surfaces of the protective shell 22 and the observation window 23, ensuring... To ensure clear video recording even in extreme conditions, the protective shell 22 is spherical in shape, allowing for easy installation of the monitoring device body 41. Combined with the silicone plate on the scraper 29, it can quickly wipe away the cleaning fluid from the outer surface of the observation window 23, ensuring clear image quality. The output end of the motor 26 is inverted T-shaped, and is fixedly connected to the bottom surface of the connecting shaft 27 via the bottom upper surface of the motor 26 output end. The output end of the water tank 25 is cylindrical, allowing for the supply of cleaning fluid to the duct while avoiding the motor 26 output end and ensuring a seal, thus guaranteeing a cleaning effect. The side wall of the ventilation duct 212 is also equipped with a fine dustproof mesh, effectively preventing dust and insects from entering the device.

[0025] In addition, an auxiliary mechanism 3 is provided on the upper surface of the mounting frame 21. The auxiliary mechanism 3 includes a connecting gear ring 31, which is slidably connected to the upper surface of the mounting frame 21. The upper surface of the connecting gear ring 31 is fixedly connected to the lower surface of the scraper rod 29. The inner wall of the connecting gear ring 31 meshes with the outer wall of the connecting gear 33. The inner wall of the connecting gear 33 is rotatably connected to a fixed shaft 32. A fan blade 34 is fixedly connected to the upper surface of the connecting gear 33. A vent hole 35 is provided through the upper surface of the mounting frame 21. A sieve plate is fixedly connected to the inner wall of the vent hole 35. Multiple sets of fixed shafts 32 are arranged in a circumferential array on the upper surface of the mounting frame 21. The bottom surface of the fixed shaft 32 is fixedly connected to the upper surface of the mounting frame 21. When the scraper rod 29 rotates, it will synchronously drive... The connecting gear ring 31 rotates, and further, the inner wall of the connecting gear ring 31 can drive the connecting gear 33 to rotate around the fixed shaft 32, further restricting the position of the connecting gear 33. The rotating connecting gear 33 can cooperate with the fan blade 34 and the vent 35 to provide sufficient airflow, providing heat dissipation for the monitoring equipment body 41, and can efficiently dissipate heat for the wireless transmission module integrated inside the monitoring equipment body 41, ensuring the transmission quality of lossless images. Moreover, the vent 35 is opened on the mounting bracket 21, which can effectively avoid water leakage caused by rain and snow. At the same time, a sieve plate is provided to further prevent dust and insects, ensuring the normal operation of the monitoring equipment body 41. The generated airflow can overflow through the ventilation slot 212, forming a stable heat dissipation airflow channel.

[0026] In this embodiment of the utility model, a support frame 4 is fixedly connected to the upper surface of the mounting frame 21, and a monitoring device body 41 is fixedly connected to the upper surface of the support frame 4. The lens of the monitoring device body 41 is set at one end of the observation window 23. The push rod 213 is arc-shaped, and a limit strip is fixedly connected to the bottom surface of the push rod 213. A threaded connection groove is opened on the side wall of the mounting plate 1, and a fixing bolt is detachably connected to the inner wall of the threaded connection groove. The setting of the support frame 4 can ensure that the monitoring device body 41 is still a certain distance from the vent 35, so that the external air introduced by the vent 35 can more comprehensively dissipate heat from the monitoring device body 41. At the same time, the limit strip and the slide groove 211 cooperate with each other to further ensure the stability of the movement path of the scraper 29. And through the fixing bolt and the threaded connection groove, the device can be installed and disassembled more conveniently.

[0027] In this invention, during use, the motor 26 starts and drives the connecting shaft 27 to rotate, thereby causing the connecting rod 28, scraper 29 and push rod 213 fixed thereon to rotate together. The scraper 29 scrapes and cleans the outer surface of the protective shell 22 and the observation window 23. At the same time, the water in the water tank 25 is transported to the nozzle 210 through the through groove inside the connecting shaft 27 and sprayed out, further ensuring the cleaning effect, thus laying the foundation for clear video recording. The rotation of the scraper 29 also drives the connecting gear ring 31 to rotate, which in turn meshes and drives the connecting gear 33 and the fan blade 34 to rotate. Finally, airflow is introduced through the vent 35 to achieve heat dissipation, ensuring that the monitoring equipment body 41 is cooled down, further ensuring the stability of video transmission quality.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
