Description

Technical Field

[0001] The invention relates to the technical field of monitoring equipment, and in particular to a self-dust removal and heat dissipation monitoring camera. Background Art

[0002] Surveillance equipment is one of the most common security equipment. It realizes real-time monitoring of a specific area and can provide us with information about people or vehicles that have passed through the area over a period of time. With the increasing popularity of closed-circuit surveillance in civil and commercial use, surveillance cameras are widely used in various fields, playing a role in protecting corporate management and social security.

[0003] Existing monitoring equipment is often installed at a high place. If the dust adheres to the protective cover of the monitoring equipment and blocks the view, it is necessary to climb up to clean it. The cleaning process is difficult and dangerous. Although some monitoring equipment will install a wiper on the front side of the lens to wipe the dust off the lens on the monitoring equipment; however, the wipers on the existing monitoring equipment are mostly exposed to the outside world, which is easy to accumulate dust. Moreover, dust and dirt will also accumulate on the wipers after use. When the mirror of the monitoring equipment is cleaned for many times, it is easy to scrape the previously accumulated dust onto the mirror of the monitoring equipment again, resulting in poor cleaning effect of the wiper.

[0004] To this end, we propose a self-dust removal and heat dissipation surveillance camera. Summary of the invention

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1. The circular windshield of the present invention is partially covered with a protective glass and partially located in a water tank. When it needs to be cleaned, the circular windshield can be rotated by a driving motor on a cleaning component, which makes cleaning convenient. Compared with the traditional method of exposing the wiper to the outside to clean the mirror surface, the present application cleans the rotating circular windshield through a cleaning component built into the water tank, which has a better cleaning effect on the mirror surface. Moreover, compared with the traditional wiper that will intermittently block the camera's line of sight during cleaning, the present application will not block the camera's line of sight during cleaning, and will not affect the camera's shooting.

[0018] 2. The present invention utilizes the output shaft of the swing frame and the driving motor to be rotationally connected through the shaft damper. When the output shaft of the driving motor rotates, the swing frame will be driven to rotate together under the damping action of the shaft damper. At this time, the U-shaped plate in a vertical state on the swing frame will rotate to contact the inner wall of the top of the water tank and leave the water surface, while the U-shaped plate in a horizontal state on the swing frame will rotate to a vertical state and enter the water surface. At this time, the swing frame is blocked by the inner wall of the top of the water tank and no longer rotates with the driving motor, but the driving motor will continue to drive the gear plate to rotate, and at this time the bevel gear and the gear plate are meshed and rotated, thereby driving the cleaning roller to rotate on its own and be located on the water surface. The inner cleaning roller scrubs the circular windshield to increase the cleaning effect of the circular windshield; in addition, it should be noted that during each regular cleaning, the rotation direction of the drive motor is opposite to that of the last cleaning, so that the U-shaped plate on the swing frame can switch positions, so that the two sets of U-shaped plates on the swing frame can be immersed in water in turn, and then the cleaning roller is immersed in water in turn, so that the dust accumulated on the cleaning roller can be washed away in the water, and the cleaning roller can rotate on its own, and can scrub the circular windshield during cleaning, and can also throw the dust it carries into the water, so that the cleaning roller can perform self-cleaning and keep clean.

[0019] 3. The present invention provides a drying unit. When the driving motor is working, it drives the piston block to move back and forth, thereby exhausting air to the outside of the pressure cylinder through the exhaust pipe and sucking air into the pressure cylinder through the air inlet pipe. The gas discharged from the exhaust pipe is blown toward the circular windshield through the air outlet on the vertical pipe, so as to dry the circular windshield rotated out of the water tank, thereby reducing the influence of moisture in the circular windshield on the line of sight of the camera body; at the same time, the gas discharged from the exhaust pipe is also blown toward the inside of the protective shell, and air is blown toward the heat dissipation holes on the rear side of the protective shell from the inside to the outside, so as to blow away the dust attached to the heat dissipation holes, thereby preventing the dust from clogging the heat dissipation holes and affecting the heat dissipation of the camera body.

[0035] like Figure 1-Figure 11 As shown, the present invention provides a self-dust-removing and heat-dissipating surveillance camera, comprising a mounting base 1, a water tank 2, a camera body 3 and a protective shell 4, the water tank 2 is fixedly arranged on the mounting base 1, a base 5 is fixedly arranged at the bottom of the protective shell 4, the base 5 is fixedly arranged on the top of the water tank 2, the camera body 3 is fixedly arranged in the protective shell 4, an opening is arranged at one end of the protective shell 4, and a protective glass 6 is arranged in the opening, and a heat dissipation hole 7 is opened at the other end of the protective shell 4; it also includes a cleaning component 8, the cleaning component 8 includes a driving motor 81 and a circular front windshield 82, the driving motor 81 is arranged inside the water tank 2, the circular front windshield 82 is arranged on the output end of the driving motor 81, a long strip opening 83 is opened on the top of the water tank 2, the top of the circular front windshield 82 moves through the long strip opening 83 and covers the protective glass 6, and the bottom of the circular front windshield 82 is located in the water tank 2.

[0036] A portion of the circular windshield 82 is arranged to cover the protective glass 6, and a portion is located in the water tank 2. When it needs to be cleaned, the circular windshield 82 can be driven to rotate by the driving motor 81 on the cleaning component 8, which makes cleaning convenient. Compared with the traditional way of exposing the wiper to the outside to clean the mirror surface, the present application uses the cleaning component 8 built into the water tank 2 to clean the rotating circular windshield 82, which has a better cleaning effect on the mirror surface. Moreover, compared with the traditional wiper that will intermittently block the camera's line of sight during cleaning, the present application will not block the camera's line of sight during cleaning, and will not affect the camera's shooting.

[0037] like Figure 1-Figure 11As shown, the cleaning component 8 also includes a scrubbing unit 84 and a drying unit 85. Two groups of vertical partitions 86 are fixedly arranged side by side in the water tank 2. An equipment bin 87 is located between the two groups of vertical partitions 86. One side of the equipment bin 87 is a cleaning bin 88, and the other side of the equipment bin 87 is a water storage bin 89. The driving motor 81 is fixedly arranged on the upper side of the equipment bin 87. The output shaft of the driving motor 81 rotates and passes through one side of the vertical partition 86 and then extends into the cleaning bin 88. The center of the circular windshield 82 is fixedly arranged on the output shaft of the driving motor 81 and is located in the cleaning bin 88. The long strip 83 is located at the top of the cleaning bin 88. The scrubbing unit 84 is arranged in the cleaning bin 88 and is connected to the output shaft of the driving motor 81. The scrubbing unit 84 contacts the circular windshield 82. The drying unit 85 is arranged on the front side wall of the water tank 2. The output shaft of the driving motor 81 rotates and passes through the front side wall of the water tank 2 and then is connected to the drying unit 85. The drying unit 85 is also connected to the protective shell 4.

[0038] The scrubbing unit 84 and the drying unit 85 are driven by the driving motor 81. The scrubbing unit 84 scrubs the circular windshield 82 to increase the cleaning effect of the circular windshield 82. The drying unit 85 dries the scrubbed circular windshield 82 to reduce the residual moisture in the circular windshield 82 and prevent it from affecting the shooting of the camera body 3.

[0039] like Figure 1-Figure 11 As shown, the central axis of the lens of the camera body 3 is perpendicular to the inner surface of the circular windshield 82 and the foot of the perpendicular is located between the center and the edge of the circular windshield 82. Moreover, when the circular windshield 82 rotates, it always covers the protective glass 6, so that the circular windshield 82 can be cleaned without affecting the shooting of the camera body 3.

[0040] like Figure 1-Figure 11 As shown, the scrubbing unit 84 includes a swing frame 841, which is composed of two groups of U-shaped plates 8411 vertically fixed to each other. The center of the swing frame 841 is rotatably connected to the output shaft of the driving motor 81 through a shaft damper 842. The circular windshield 82 moves through the two groups of U-shaped plates 8411. The scrubbing unit 84 also includes cleaning rollers 843. The cleaning rollers 843 are rotatably arranged on the inner walls of one side of the two groups of U-shaped plates 8411 through bearings. The central axis of the cleaning roller 843 points vertically to the central axis of the circular windshield 82. The circular windshield 82 is in close contact with the outside of the cleaning roller 843. The outside of the cleaning roller 843 is a sponge cover, and the circular windshield 82 is cleaned by squeezing and rolling the sponge cover.

[0041] like Figure 1-Figure 11As shown, the scrubbing unit 84 includes a gear plate 844 and a bevel gear 845. The gear plate 844 is fixed on the output shaft of the driving motor 81, and the gear plate 844 is located on both sides of the circular windshield 82. The bevel gear 845 is fixed on one end of the cleaning roller 843, and the bevel gear 845 is meshed with the gear plate 844.

[0042] The swing frame 841 is connected to the output shaft of the driving motor 81 through the shaft damper 842. When the output shaft of the driving motor 81 rotates, the swing frame 841 is driven to rotate together under the damping action of the shaft damper 842. At this time, the U-shaped plate 8411 on the swing frame 841 in a vertical state will rotate to contact the inner wall of the top of the water tank 2 and leave the water surface, and the U-shaped plate 8411 on the swing frame 841 in a horizontal state will rotate to a vertical state and enter the water surface. At this time, the swing frame 841 is blocked by the inner wall of the top of the water tank 2 and no longer rotates with the driving motor 81, but the driving motor 81 will continue to drive the gear plate 844 to rotate, and at this time the bevel gear 845 is meshed with the gear plate 844 to rotate, thereby driving The cleaning roller 843 rotates on its own, and the cleaning roller 843 located in the water surface scrubs the circular windshield 82, thereby increasing the cleaning effect of the circular windshield 82; in addition, it should be noted that during each regular cleaning, the rotation direction of the driving motor 81 is opposite to the rotation direction during the last cleaning, so that the U-shaped plate 8411 on the swing frame 841 can switch positions, so that the two sets of U-shaped plates 8411 on the swing frame 841 can be immersed in water in turn, and then the cleaning roller 843 can be immersed in water in turn, so that the dust accumulated on the cleaning roller 843 can be washed away in the water, and the cleaning roller 843 can rotate on its own, so that it can scrub the circular windshield 82 during cleaning, and can also throw the dust it carries into the water.

[0043] like Figure 1-Figure 11As shown, the drying unit 85 includes an eccentric wheel 851, a pressure cylinder 852, a push rod 853 and a piston block 854. The eccentric wheel 851 is fixedly arranged on the output shaft of the driving motor 81 and is located at the front side of the water tank 2. The pressure cylinder 852 is fixedly arranged on the side wall of the front side of the water tank 2 and is located on both sides of the eccentric wheel 851. The piston block 854 is in sliding and sealing cooperation with the inside of the pressure cylinder 852. The push rod 853 slides horizontally through the inner wall of the pressure cylinder 852 toward one side of the eccentric wheel 851, and the central axis of the push rod 853 is perpendicular to the central axis of the output shaft of the driving motor 81. The push rod 853 is located inside the pressure cylinder 852. One end is fixedly connected to the piston block 854, and the other end of the push rod 853 located outside the pressure cylinder 852 is fixedly connected to the arc block 855, the eccentric wheel 851 is in sliding contact with the arc block 855, and a return spring 856 is connected between the piston block 854 and the inner wall of the pressure cylinder 852 on the side away from the eccentric wheel 851. An exhaust pipe 857 and an intake pipe 858 are connected on the inner wall of the pressure cylinder 852 on the side away from the eccentric wheel 851. A one-way valve 1 is connected in series to the exhaust pipe 857, and a one-way valve 2 is connected in series to the intake pipe 858. One end of the exhaust pipe 857 extends into the interior of the protective shell 4 and points to the heat dissipation hole 7 on the inner wall on the rear side of the protective shell 4.

[0044] like Figure 1-Figure 11 As shown, the exhaust pipe 857 is also connected to a vertical pipe 859 , the bottom end of the vertical pipe 859 is fixedly connected to the top of the water tank 2 and is located on one side of the circular windshield 82 , and multiple groups of air outlets 8510 are opened on the vertical pipe 859 , and the air outlets 8510 face the circular windshield 82 .

[0045] By means of the provided drying unit 85, when the driving motor 81 is working, the piston block 854 is driven to move back and forth, thereby exhausting air to the outside of the pressure cylinder 852 through the exhaust pipe 857, and sucking air into the pressure cylinder 852 through the air inlet pipe 858. The gas discharged from the exhaust pipe 857 is blown toward the circular windshield 82 through the air outlet 8510 on the vertical pipe 859, so as to dry the circular windshield 82 rotated out of the water tank 2, thereby reducing the influence of moisture in the circular windshield 82 on the line of sight of the camera body 3; at the same time, the gas discharged from the exhaust pipe 857 is also blown toward the inside of the protective shell 4, and the heat dissipation holes 7 on the rear side of the protective shell 4 are blown from the inside to the outside, so as to blow away the dust attached to the heat dissipation holes 7, thereby preventing the dust from clogging the heat dissipation holes 7 and affecting the heat dissipation of the camera body 3.

[0046] like Figure 1-Figure 11 As shown, a water pump 21 is fixedly provided at the bottom of the equipment bin 87. The water suction end of the water pump 21 is connected to the inside of the water storage bin 89 through a pipe 1, and the water outlet end of the water pump 21 is connected to the inside of the cleaning bin 88 through a pipe 2. A solenoid valve 22 is connected in series to the pipe 2.

[0047] When the circular windshield 82 needs to be cleaned, the solenoid valve 22 is controlled to open and the water pump 21 is started to pump the water in the water storage tank 89 into the cleaning tank 88. The volume of the water storage tank 89 is much larger than the volume of the cleaning tank 88. The water in the water storage tank 89 can be used to clean the cleaning tank 88 multiple times.

[0048] like Figure 1-Figure 11 As shown, a sewage pipe 23 is connected to one side of the bottom of the cleaning chamber 88, and a solenoid valve 24 is connected in series to the sewage pipe 23. A liquid level sensor 25 is also provided on the upper side of the inner wall of the cleaning chamber 88. When cleaning is completed, the solenoid valve 24 is opened, and the sewage in the cleaning chamber 88 is discharged to the outside.

[0049] like Figure 1-Figure 11 As shown, a rainwater collecting bucket 26 is connected to the top of the water storage tank 89, and a filter net 27 is fixedly provided inside the rainwater collecting bucket 26. Rainwater is collected by the rainwater collecting bucket 26, and the filter net 27 can filter out external impurities, so that water resources can be comprehensively utilized and energy can be saved.

[0050] During specific use, the driving motor 81, the water pump 21, the solenoid valve 1 22, the solenoid valve 24 and the liquid level sensor 25 can be turned on or off through the monitoring central control system. When it is necessary to clean the dust on the circular windshield 82, firstly, the solenoid valve 1 22 is controlled to be opened, the solenoid valve 24 is controlled to be closed and the water pump 21 is controlled to work, and the tap water or the collected rainwater pre-stored in the water storage tank 89 is passed into the cleaning tank 88. When the water surface level reaches the position of the liquid level sensor 25, the liquid level sensor 25 transmits the liquid level signal to the central control system, and the central control system controls the water pump 21 to be turned off. At this time, the liquid level in the cleaning tank 88 immerses the U-shaped plate 8411 in a vertical state on the swing frame 841, and at the same time, the liquid level in the cleaning tank 88 just reaches the bottom of the U-shaped plate 8411 in a horizontal state on the swing frame 841; then the driving motor 81 is controlled to work, and the driving motor 81 drives the circular windshield 82 to rotate, so that the water in the cleaning tank 88 cleans the circular windshield 82;

[0051] At the same time, since the swing frame 841 is connected to the output shaft of the driving motor 81 through the shaft damper 842, when the output shaft of the driving motor 81 rotates, the swing frame 841 will be driven to rotate together under the damping action of the shaft damper 842. At this time, the U-shaped plate 8411 in a vertical state on the swing frame 841 will rotate to contact the inner wall of the top of the water tank 2 and leave the water surface, while the U-shaped plate 8411 in a horizontal state on the swing frame 841 will rotate to a vertical state and enter the water surface. At this time, the swing frame 841 is blocked by the inner wall of the top of the water tank 2 and no longer rotates with the driving motor 81, but the driving motor 81 will continue to drive the gear plate 844 to rotate, and at this time the bevel gear 845 is meshed and rotated with the gear plate 844, thereby driving the cleaning roller 843 to rotate on its own and be located on the water surface. The cleaning roller 843 scrubs the surface of the circular windshield 82 to increase the cleaning effect of the circular windshield 82, and the cleaning roller 843 located above the water surface squeezes and scrapes the water on the surface of the circular windshield 82, and squeezes the excess water to flow onto the water surface. The cleaned circular windshield 82 rotates and moves out of the long strip 83. During the cleaning process, the circular windshield 82 always covers the laminated protective glass 6. Compared with the traditional wiper that will intermittently block the camera's line of sight during cleaning, the present application will not block the camera's line of sight during cleaning, and will not affect the camera's shooting; in addition, the driving motor 81 can be controlled to drive the circular windshield 82 to rotate for multiple circles until the dust on the circular windshield 82 is cleaned and no longer blocks the camera body 3's line of sight;

[0052] In addition, when the driving motor 81 is working, the eccentric wheel 851 is also driven to rotate. When the eccentric wheel 851 presses the arc block 855 toward the side of the pressure cylinder 852, the push rod 853 and the piston block 854 are driven to move together, and the return spring 856 is compressed. When the eccentric wheel 851 starts to move away from the pressure cylinder 852, the arc block 855, the push rod 853 and the piston block 854 are driven to move toward the side of the eccentric wheel 851 under the action of the rebound force of the return spring 856. Therefore, the eccentric wheel 851 is always in close sliding contact with the arc block 855, so that the piston block 854 can be driven to move back and forth, thereby expelling the exhaust gas through the exhaust pipe 857. The air is exhausted from the outside of the pressure cylinder 852 and sucked into the pressure cylinder 852 through the air inlet pipe 858. The gas exhausted from the exhaust pipe 857 is blown toward the circular windshield 82 through the air outlet 8510 on the vertical pipe 859, so as to dry the circular windshield 82 rotated out of the water tank 2 and reduce the influence of the moisture of the circular windshield 82 on the line of sight of the camera body 3.
