Description

Technical Field

[0001] This utility model relates to the field of equipment protection, specifically to a cleaning and protection device for sensor equipment. Background Technology

[0002] With the continuous advancement of intelligent transportation and road informatization, cameras, optical sensors and other sensing devices are widely deployed in road information collection systems to realize functions such as traffic flow statistics and vehicle operation status monitoring.

[0003] These types of sensors are typically installed along roadsides or on roadside facilities for extended periods. Their observation windows directly face the road environment and are constantly exposed to complex outdoor conditions, making them susceptible to damage from collisions or impacts. Furthermore, the large amounts of dust, exhaust fumes, oil spills, and rain and snow generated by vehicles on the road easily adhere to the surface of the optical device's observation window, resulting in dust accumulation, water stains, or oil film contamination, thus reducing light transmittance.

[0004] Therefore, in order to solve the problems of lack of protection and poor light transmittance of the observation window of the sensing equipment when it is in outdoor working conditions for a long time, there is an urgent need for a cleaning and protection device for the sensing equipment that can not only ensure the light transmittance of the observation window, but also protect the observation window. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a cleaning and protection device for sensing equipment, which can not only ensure the light transmittance of the observation window, but also protect the observation window.

[0006] The present invention relates to a cleaning and protection device for sensing equipment, comprising a housing disposed on the observation window of the sensing equipment; an annular window groove is provided on the housing, and a transparent window plate adapted to the shape of the annular window groove is embedded in the annular window groove; the transparent window plate is rotatably mounted on the housing via a pivot located at its center.

[0007] A cleaning frame is also embedded in the annular window slot. The cleaning frame is set on the outer surface of the transparent window plate, and several cleaning strips are set on the side of the cleaning frame facing the transparent window plate.

[0008] Furthermore, a magnetic suction component that cooperates with the transparent window disc is provided in the annular window groove.

[0009] Furthermore, the magnetic attraction component includes a neodymium iron boron magnet disposed on the wall of the annular window groove and a magnetic steel sheet disposed on the outer periphery of the transparent window disk and capable of adsorbing with the neodymium iron boron magnet.

[0010] Furthermore, the bottom of the annular window groove is tilted outward at an angle of θ.

[0011] Furthermore, a drain hole is provided at the bottom of the annular window groove.

[0012] Furthermore, the cleaning frame is made of stainless steel, aluminum alloy, or engineering plastic.

[0013] The beneficial effects of this utility model are as follows: This utility model discloses a cleaning and protection device for sensing equipment. By setting a shell on the outside of the observation window of the sensing equipment, and setting an annular window groove on the shell, a transparent window plate is embedded in the annular window groove, allowing the observation window to maintain light transmission while also being effectively protected. By setting a cleaning frame and arranging several cleaning strips on the side facing the transparent window plate, the surface of the transparent window plate can be wiped clean, further ensuring the light transmission of the observation window.

[0019] The present invention will be further described below with reference to the accompanying drawings, as shown in the figures:

[0020] The present invention relates to a cleaning and protection device for a sensing device, comprising a housing 1 disposed on the observation window of the sensing device; an annular window groove 2 is provided on the housing 1, and a transparent window plate 3 adapted to the shape of the annular window groove 2 is embedded in the annular window groove 2; the transparent window plate 3 is rotatably mounted on the housing 1 by means of a rotating shaft located at its center.

[0021] A cleaning frame 4 is also embedded within the annular window groove 2. The cleaning frame 4 is disposed on the outer surface of the transparent window plate 3, and several cleaning strips 5 are provided on the side of the cleaning frame 4 facing the transparent window plate 3. The transparent window plate 3 can be a single annular transparent sheet or composed of two fan-shaped transparent sheets combined by an interlocking tongue structure. One end of the rotating shaft is fixed to the outer casing 1, and the other end extends through the cleaning frame 4 via a through hole 6, forming an extension end. The extension end is used to operate the rotating shaft to rotate, thereby driving the rotation of the transparent window plate 3. It should be noted that, to ensure cleaning effectiveness, the cleaning frame 4 is fixedly embedded in the annular window groove 2 with screws and disposed on the outer surface of the transparent window plate 3. Since the transparent window plate 3 needs to rotate, it is movably embedded in the annular window groove 2, allowing the cleaning frame 4 to move relative to the transparent window plate 3. Further details will not be elaborated here.

[0022] By setting a housing 1 on the outside of the observation window of the sensing device and forming an annular window groove 2 on the housing 1, a rotatable transparent window disk 3 is embedded in the annular window groove 2, so that the observation window is covered by the transparent window disk 3 under normal working conditions, thereby forming physical isolation and buffer for the original observation window of the sensing device, and thus effectively reducing the risk of damage to the observation window caused by collisions or impacts of external objects.

[0023] Meanwhile, by setting a cleaning frame 4 within the annular window groove 2 and arranging several cleaning strips 5 on the side facing the transparent window disk 3, the surface of the transparent window disk 3 can be wiped clean as it rotates via the pivot. This effectively removes dust, water stains, and oil adhering to the surface of the transparent window disk 3, ensuring good light transmission performance. This structure achieves both protection and rapid cleaning of the observation window, which is beneficial for improving the stability and service life of the sensing equipment under complex outdoor conditions.

[0024] In this embodiment, a magnetic suction component that cooperates with the transparent window disk 3 is provided in the annular window groove 2.

[0025] By setting a magnetic suction component in the annular window slot 2 that cooperates with the transparent window disk 3, the transparent window disk 3 can be reliably positioned or limited at a predetermined position, preventing it from rotating unexpectedly under the vibration of the sensing device or external impact, thereby ensuring the stability and light transmission consistency of the observation window in the working state.

[0026] In this embodiment, the magnetic attraction component includes a neodymium iron boron magnet disposed on the wall of the annular window groove 2 and a magnetic steel sheet disposed on the outer periphery of the transparent window disk 3 and capable of adsorbing with the neodymium iron boron magnet.

[0027] By specifically configuring the magnetic attraction components as neodymium iron boron magnets on the wall of the annular window groove 2 and magnetic steel sheets on the outer periphery of the transparent window disk 3, a stable and reliable magnetic attraction force can be formed when the transparent window disk 3 rotates to a designated position, achieving precise positioning and effective limiting. This structure can obtain a large attraction force and good repeatability without a complex mechanical locking mechanism, which can ensure the stability of the transparent window disk 3 in the working state, while reducing structural complexity and manufacturing costs.

[0028] In this embodiment, the bottom of the annular window groove 2 is tilted outward at an angle of θ. The angle θ is the angle between the downward-sloping surface on the outer side of the bottom and the horizontal plane, and its value can be any value between 1° and 2°.

[0029] By setting the bottom of the annular window groove 2 to be inclined outward at an angle of θ, rainwater, condensation, or water stains generated during the cleaning process that adhere to or enter the annular window groove 2 can be naturally discharged outward under gravity, preventing liquid from accumulating in the groove and thus reducing the risk of corrosion or contamination to components such as the cleaning frame 4 and cleaning strip 5. At the same time, this inclined structure helps reduce dirt retention, improves the device's self-draining capacity, and further enhances the reliability and service life of the cleaning protection device in complex outdoor environments.

[0030] In this embodiment, a drain hole is provided at the bottom of the annular window groove 2.

[0031] By providing a drain hole at the bottom of the annular window groove 2, a clear discharge channel can be provided for dust, water stains, and sewage generated during the cleaning process, allowing contaminants to be discharged promptly under gravity or rinsing action, preventing them from stagnating and accumulating within the annular window groove 2. This drain hole, in conjunction with the inclined bottom structure, further improves the drainage and sewage discharge efficiency of the annular window groove 2, thereby further reducing the risk of contamination or corrosion of internal components.

[0032] In this embodiment, the cleaning frame 4 is made of stainless steel, aluminum alloy or engineering plastic.

[0033] By using stainless steel, aluminum alloy or engineering plastic to make the cleaning frame 4, the corrosion resistance and structural stability of the cleaning frame 4 in long-term outdoor use environment can be significantly improved, avoiding deformation or failure of the cleaning frame 4 due to rust or aging, thereby ensuring a stable contact effect between the cleaning strip 5 and the transparent window plate 3.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
