Description
Technical Field
[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, and in particular to an explosion-proof self-cleaning camera protective cover. Background Technology
[0002] In the construction of a smart construction site for a pumped storage power station, in order to accurately control the on-site construction progress and project quality, the digital platform needs to collect information from each construction site in a timely manner, which basically relies on the monitoring cameras installed on the construction site.
[0003] Currently, the surveillance cameras used on construction sites are all ordinary cameras. Most focus on improving color accuracy and image clarity, but their ability to prevent external interference is insufficient, making them prone to malfunction due to external explosion vibrations. Simultaneously, due to the impact of construction excavation, the dust concentration in underground tunnels is high, and the cameras are easily contaminated by dust, requiring frequent cleaning. Because it is impossible to work close to the excavation face, timely collection of excavation data is not possible, hindering the management of tunnel excavation progress and quality by the smart construction site system. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an explosion-proof self-cleaning camera cover to address the above-mentioned problems.
[0005] The technical solution adopted in this utility model is: an explosion-proof self-cleaning camera protective cover, comprising:
[0006] The camera mounting base has an internal cavity for mounting the camera body;
[0007] A set of protective covers, symmetrically and rotatably installed at the bottom of the camera mounting base, corresponds to the camera body. The set of protective covers can rotate and fit together to form a hemispherical dome to protect the camera body.
[0008] The drive assembly is located inside the cavity of the camera mounting base. The drive assembly is connected to the protective cover in a transmission manner. The drive assembly is used to drive a group of protective covers to rotate synchronously and open and close.
[0009] The cleaning component is arranged in a ring inside the side wall of the camera mounting base, and the cleaning component can clean the camera body.
[0010] The controller is connected in communication with both the drive and cleaning components, and can control the opening and closing of the drive and cleaning components.
[0011] Using the above-mentioned technical means, when blasting operations are to be carried out at the construction site, the controller controls the drive component to close the protective cover, forming a hemispherical dome that can protect the camera body from damage by flying rocks from the excavation face. Furthermore, the controller controls the cleaning component to clean the camera body, ensuring that the camera body can obtain a better monitoring image in a high-concentration dust environment.
[0012] In some embodiments, the drive assembly includes a motor and a bevel gear set. The motor is mounted on the top of the camera body via a mounting bracket. The output end of the motor is connected to the bevel gear set. The output end of the bevel gear set is respectively connected to a set of the protective covers, such that the rotation directions of the set of protective covers are opposite.
[0013] In some embodiments, the bevel gear set includes a top bevel gear and side bevel gears. The top bevel gear is connected to the output end of the motor. Side bevel gears are symmetrically meshed on both sides of the top bevel gear. Both sides of the side bevel gears are connected to a rotating shaft. One rotating shaft is connected to a disc at one end of the protective cover, and the other rotating shaft is connected to a disc at the remaining end of the protective cover. A pair of fixed shafts arranged coaxially with the rotating shafts are installed on the inner wall of the camera mounting base. The fixed shafts on both sides are rotatably connected to the discs.
[0014] In some embodiments, the cleaning component includes a flow pipe, an air duct, and a water pipe. An arc-shaped flow pipe is provided in the side wall of the camera mounting base from top to bottom. The top of the flow pipe is connected to the air duct and the water pipe. The air duct is provided with an air source and an air source valve, and the water pipe is provided with a water source and a water source valve. The controller can control the opening and closing of the air source valve and the water source valve. The bottom of the arc-shaped flow pipe is connected to an annular flow pipe. At least part of the bottom of the annular flow pipe is exposed above the camera mounting base. The annular flow pipe is provided with a plurality of nozzles facing the camera body along the circumferential direction.
[0015] In some embodiments, a soft brush is provided at the bottom peripheral edge of the inner wall of the camera mounting base. The soft brush abuts against the outer wall of the protective cover and can brush the outer wall of the protective cover when it is opened and closed.
[0016] The beneficial effects of this utility model are:
[0017] 1. When blasting operations are required at the construction site, the controller controls the drive assembly, which in turn drives the protective cover to rotate and close, forming a hemispherical dome. This protects the camera body from the impact of fragments generated by external explosions, making it particularly suitable for camera equipment in blasting environments. When facing situations with high dust concentrations and easy contamination in underground caverns, the controller can also control the cleaning assembly to first wash and then dry the camera body, ensuring its cleanliness.

[0030] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.
[0031] Combination Figures 1 to 6 As shown, this embodiment is an explosion-proof self-cleaning camera protective cover, including a camera mounting base 14, a set of protective covers 7, a drive assembly, a cleaning assembly, and a controller. The camera mounting base 14 has an internal cavity for mounting the camera body 6. A set of protective covers 7 is symmetrically and rotatably mounted on the bottom of the camera mounting base 14. The protective covers 7 correspond to the camera body 6 inside the cavity, and the set of protective covers 7 can rotate to form a hemispherical dome to protect the camera body 6. A drive assembly is located inside the cavity of the camera mounting base 14, and the drive assembly is connected to the protective covers 7. The drive assembly drives the set of protective covers 7 to rotate synchronously and open and close. A cleaning assembly is circumferentially located inside the side wall of the camera mounting base 14, and the cleaning assembly can clean the camera body 6. Both the drive assembly and the cleaning assembly are communicatively connected to the controller, which can control the opening and closing of the drive assembly and the cleaning assembly.
[0032] In some implementation schemes, such as Figure 1 As shown, the drive assembly includes a motor 1 and a bevel gear set. The motor 1 is mounted on the top of the camera body 6 via a mounting bracket 2. The output end of the motor 1 is connected to the bevel gear set. The output ends on both sides of the bevel gear set are respectively connected to a set of protective covers 7, so that the rotation directions of the set of protective covers 7 are opposite.
[0033] Furthermore, the bevel gear set includes a top bevel gear 8 and side bevel gears 9. The top bevel gear 8 is connected to the output end of the motor 1. The two sides of the top bevel gear 8 are symmetrically meshed with side bevel gears 9. Both sides of the side bevel gears 9 are connected to a rotating shaft 3. One side of the rotating shaft 3 is connected to a disc 5 at the end of any of the protective covers 7. The other side of the rotating shaft 3 is connected to a disc 5 at the end of the remaining protective cover 7. The inner wall of the camera mounting base 14 is equipped with a pair of fixed shafts 4 arranged coaxially with the rotating shafts 3. The fixed shafts 4 on both sides are rotatably connected to the discs 5.
[0034] In some implementation schemes, such as Figure 1 , Figure 2 and Figure 4 As shown, the cleaning assembly includes a flow pipe 12, an air duct 10, and a water pipe 11. An arc-shaped flow pipe 12 is provided inside the side wall of the camera mounting base 14 from top to bottom. The top of the flow pipe 12 is connected to the air duct 10 and the water pipe 11. The air duct 10 is equipped with an air source and an air source valve, and the water pipe 11 is equipped with a water source and a water source valve. The controller can control the opening and closing of the air source valve and the water source valve. The bottom of the arc-shaped flow pipe 12 is connected to an annular flow pipe 12. At least part of the bottom of the annular flow pipe 12 is exposed above the camera mounting base 14. The annular flow pipe 12 has multiple nozzles facing the camera body 6 along its circumferential direction. Specifically, in this embodiment, the annular flow pipe 12 has 25 nozzles evenly arranged along its circumferential direction. Simultaneously, in this embodiment, the air and water sources need to be controlled with appropriate air and water pressures to ensure that the airflow and water flow can properly clean the camera body 6 without causing a strong impact on it.
[0035] Furthermore, the camera body 6 is cleaned using air and water sources. Since the dust concentration at the construction site is high, the protection level of the camera body 6 in this embodiment needs to meet certain requirements. The waterproof level needs to reach IPX6 or above, and the dustproof level needs to reach IP6X or above, so as to ensure that the camera body 6 is not only unaffected by the high dust environment at the construction site, but also undamaged during the air-water linkage cleaning.
[0036] Furthermore, in addition to conventional materials suitable for manufacturing explosion-proof shields 7, in this embodiment, the shield 7 can also be made of polycarbonate and laminated glass. These two materials ensure that the shield 7 has sufficient strength to withstand blast impacts while providing a clear and transparent viewing window, meeting the need for the camera body 6 to maintain monitoring even when the shield 7 is closed under special circumstances. Specifically, polycarbonate has an impact resistance more than 200 times that of glass, while maintaining high light transmittance (approximately 90%) and being lightweight. Laminated glass, made by sandwiching one or more layers of PVB (polyvinyl butyral) film between two or more panes of glass, maintains the integrity of its overall structure even after breaking due to impact, unlike ordinary glass which scatters into fragments. It provides excellent optical clarity and good explosion-proof performance.
[0037] Furthermore, if the protective cover 7 is made of the aforementioned transparent material, the cleaning component in this embodiment can also clean the protective cover 7 when it is in a closed state to ensure the cleanliness of the protective cover 7 and thus meet the clarity requirements of the data collected by the camera.
[0038] In some implementation schemes, such as Figure 2 and Figure 4As shown, a soft brush 13 is provided at the bottom periphery of the inner wall of the camera mounting base 14. The soft brush 13 abuts against the outer wall of the protective cover 7 and can brush the outer wall of the protective cover 7 when it is opened and closed.
[0039] The implementation principle of an explosion-proof self-cleaning camera protective cover is as follows:
[0040] After the camera body 6 is installed and in normal working condition, the protective cover 7 is in the open state.
[0041] When the construction site is ready for excavation and blasting, the staff receives a message and sends a control signal through the controller. The motor 1 receives the control signal and drives the top bevel gear 8 to rotate. The top bevel gear 8 drives the side bevel gears 9 on both sides to rotate. The side bevel gears 9 rotate in opposite directions and each drives the corresponding rotating shaft 3 and disc 5 to rotate. This causes the disc 5 to drive the fixedly connected protective cover 7 to rotate. Thus, a set of protective covers 7 rotates until it is in a closed state to protect the camera body 6.
[0042] like Figure 5 and Figure 6 As shown, after the blasting operation is completed, if the camera body 6 still needs to continue to collect data from the excavation face, the controller will control the motor 1 to run in reverse. The motor 1 drives the bevel gear set to make a set of protective covers 7 rotate until it is in the open state. During this process, the soft brush 13 can brush the protective covers 7.
[0043] After excavation and blasting operations are completed, the high dust concentration in the environment can negatively impact the data acquisition of the camera body 6. In this case, the water supply valve of water pipe 11 is opened using the controller. Water flows through the circulation pipe 12 and, under pressure, washes the camera body 6. After washing, the water supply valve of water pipe 11 is closed. Then, the air supply valve of air duct 10 is opened. Air flows through the circulation pipe 12 and, under pressure, dries the camera body 6 until it is clean and ready for continued use.
[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
