Description

Technical Field

[0001] The present invention relates to the technical field of security monitoring, and in particular to a weak current engineering security monitoring device. Background Art

[0002] The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in a closed loop, and constitutes an independent and complete system from camera to image display and recording. It can reflect the monitored object in real time, vividly and truthfully, and can replace manual long-term monitoring in harsh environments and record it through a video recorder. Video security monitoring system refers to an electronic system or network that uses video detection technology to monitor the defense area and display and record on-site images in real time.

[0003] At present, the core equipment of security monitoring equipment is security monitoring camera, which is equipped with lens, and the direction of the lens is controlled by the pan / tilt. The image pictures obtained by the security monitoring camera through the lens are uploaded to the cloud through the network. Among them, because the lens is in an exposed state, the clarity and transparency of the lens is the key to the security monitoring camera to obtain high-quality images. At present, the main factor affecting the clarity and transparency of the lens is adhesion. For example, the free oil molecules produced by exhaust emissions in the air will be mixed with dust and adhere to the surface of the lens, and the glue produced by trees, bird droppings and dead flying insects will adhere to the surface of the lens. Such adhesion of dirt has strong adhesion ability, and it is difficult to effectively clean it with different cleaning methods. Moreover, it is easy to form water stains and stains on the surface of the lens during cleaning, and the cleaning effect is poor. In addition, the cleaning parts are usually cleaning cotton, which is easy to be contaminated. The cleaning cotton after secondary contamination will transfer its own dirt to the lens when cleaning the lens again.

[0004] To this end, the present invention proposes a weak current engineering security monitoring device. Summary of the invention

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In the present invention, a revolving suspension and a water spray pipe are arranged on a suspension seat, and a rotating shaft is arranged on the suspension to drive a rotating cloth cleaning disk. After the suspension revolves and drives the cloth cleaning disk to be located below the water spray pipe, the water spray pipe can spray water on the cloth cleaning disk. When the suspension revolves until the cloth cleaning disk and the lens are in contact, the rotation axis of the cloth cleaning disk is perpendicular to the lens. At this time, the rotating shaft is controlled to rotate at a high speed, and the cloth cleaning disk will use centrifugal force to wipe off the adhered dirt on the lens, which has the advantage of stronger lens cleaning force.

[0026] 2. In the present invention, when the cloth cleaning disk is set to rotate at high speed, part of the adhered matter and implicit water on it will be centrifugally thrown off. Therefore, this function cooperates with the revolving suspension and the water spraying pipe to facilitate the water replenishment and centrifugal movement of the contaminated cloth cleaning disk, so as to achieve the self-cleaning and spin-drying treatment of the cloth cleaning disk. Then, when the cloth cleaning disk with greatly reduced humidity is controlled to rotate centrifugally to wipe the lens, water marks and water stains on the lens surface can be effectively eliminated. Therefore, this setting not only improves the cleaning degree of the lens after wiping, but also has the function of self-cleaning of the cloth cleaning disk, which is convenient for multiple uses of the cloth cleaning disk.

[0027] 3. In the present invention, an annular turntable and a linkage transmission combination for connecting the annular turntable and the rotating shaft are arranged at the bottom of the suspension seat, so that the rotation of the rotating shaft is driven by the annular turntable which does not occupy space, wherein the linkage transmission combination is a belt drive structure. This arrangement greatly reduces the weight and occupied space of the components for controlling the rotation of the rotating shaft, making the high-speed rotation control of the rotating shaft more reliable and stable.

[0028] 4. In the present invention, a driving disc is arranged at the bottom of the suspension seat for horizontal sliding, and then the suspension rod on the suspension is arranged to be an elastic telescopic structure, and a roller is arranged on the suspension rod to abut against the outer circumference of the driving disc. Therefore, when the suspension revolves, the telescopic action of the suspension rod is controlled by the position of the driving disc, and when the driving disc is controlled to slide relative to the suspension shaft, the cloth strip cleaning disc can increase the squeezing force on the lens, making it easier to clean up adhesions with stronger adhesion strength.

[0029] 5. In the invention, the sliding of the driving disc will cause the suspension rod to extend and retract when the suspension is in operation. When the suspension rod extends and retracts, the distance between the large pulley and the suspension shaft changes. When the rotational angular velocity of the suspension is constant, the large pulley will show a state of speed change. That is, when the suspension is in operation, the cloth strip cleaning disc and the lens are in a low speed state relative to each other, and it is in a highest speed state when the distance between the cloth strip cleaning disc and the lens is the farthest. This arrangement has the function of continuous centrifugal drainage and periodic cleaning of the lens after absorbing water once, which greatly improves the efficiency of lens cleaning.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example 1

[0044] See also Figure 1-7 A weak current engineering security monitoring device includes a monitoring camera 1, a lens 2 is arranged at the front end of the monitoring camera 1, the monitoring camera 1 is used for security monitoring, and a control pan-tilt 3 is connected to one side of the monitoring camera 1, and the function of the control pan-tilt 3 is to adjust the direction of the lens 2.

[0045] In the present technical solution, a suspension seat 4 is also included. The suspension seat 4 is used to suspend the device. When in use, it is connected to the external mounting plate by bolts. The suspension seat 4 can be a disc-shaped structure. The bottom of the suspension seat 4 is fixedly connected to a suspension shaft 5 connected to the control pan / tilt 3. When in use, a wire passage is opened in the suspension shaft 5 to facilitate the wiring of the wires of the device. The suspension shaft 5 is connected to a suspension 6 that revolves relative to the suspension shaft 5, that is, the suspension 6 can rotate around the suspension shaft 5. The bottom of the suspension 6 is rotatably connected to a rotating shaft 7 whose axis is perpendicular and intersecting with the axis of the suspension shaft 5. In specific implementation, it is preferred that the suspension 6 includes a suspension rod 61 and a vertical plate 62. One end of the suspension rod 61 is welded with a rotating sleeve 611 that is sleeved on the outside of the suspension shaft 5. A bearing is provided between the rotating sleeve 611 and the suspension shaft 5. The top of the vertical plate 62 is fixedly connected to the bottom of the suspension rod 61 and close to the free end. The rotating shaft 7 is rotatably connected to the bottom of the vertical plate 62.

[0046] Furthermore, the bottom of the suspension seat 4 is fixedly connected to a control motor 101, and the output of the control motor 101 is fixedly connected to a driving gear 1011. The outer fixed sleeve of the rotating sleeve 611 is provided with a passive gear 6111 meshing with the driving gear 1011. The control motor 101 drives the rotating sleeve 611 to rotate through the meshing cooperation between the driving gear 1011 and the passive gear 6111, thereby driving the suspension 6 to rotate around the suspension shaft 5.

[0047] A cloth cleaning disk 8 is provided on one end of the rotating shaft 7 facing the axis of the suspension shaft 5. When the rotating shaft 7 rotates, the cloth cleaning disk 8 can be driven to rotate. When in use, the lens 2 is first controlled to be in a horizontal orientation by controlling the pan / tilt head 3, and then the suspension 6 is controlled to rotate to a position where the cloth cleaning disk 8 and the front side of the lens 2 are relative to each other. When the rotating shaft 7 is controlled to rotate, the cloth cleaning disk 8 will rotate and clean the adhered dirt on the surface of the lens at the same time.

[0048] Among them, the cloth strip cleaning disk 8 includes a conical disk 81 and a short cloth rope 82 that is evenly and fixedly arranged on the large end face of the conical disk 81. The cross-section of the short cloth rope 82 is circular, and the small end face of the conical disk 81 is fixedly connected to the rotating shaft 7. Therefore, when the rotating shaft 7 rotates at a high speed, the short cloth rope 82 will twist and swing laterally under the action of centrifugal force. This arrangement allows a large number of short cloth ropes 82 to centrifugally clean away adhesions, water stains and water marks on the lens 2, with greater cleaning power. In addition, the centrifugal movement of the short cloth rope 82 can also dehydrate and remove dirt, making it easy to throw away the sewage mixture thereon, thereby realizing a self-cleaning function and not affecting subsequent recycling.

[0049] A circular turntable 106 is provided at the bottom of the suspension seat 4, and the suspension shaft 5 is located inside the circular turntable 106 and the two are coaxial. In specific implementation, a limit sleeve can be welded at the bottom of the suspension seat 4 and sleeved on the outside of the circular turntable 106. The limit sleeve and the circular turntable 106 rotate in coordination. A linkage transmission combination 9 is provided on the suspension 6. Under the action of the linkage transmission combination 9, when the suspension 6 moves circumferentially relative to the circular turntable 106, the rotating shaft 7 rotates. In other words, the rotation of the rotating shaft 7 is achieved by the relative movement of the suspension 6 and the circular turntable 106 through the conversion of the linkage transmission combination 9.

[0050] Specifically, the linkage transmission combination 9 includes a large pulley 91, a transmission belt 92 and a small pulley 93. The small pulley 93 is fixedly arranged at the other end of the rotating shaft 7. The large pulley 91 is rotatably connected to the other end of the suspension rod 61 and is connected to the small pulley 93 through the transmission belt 92. The outer wall of the transmission belt 92 between the large pulley 91 and the annular turntable 106 is abutted against the lower end of the annular turntable 106. The transmission belt 92 is a synchronous belt. The annular turntable 106 uses friction to drive the transmission belt 92 to operate. When the transmission belt 92 operates, it drives the small pulley 93 to rotate at high speed.

[0051] In this embodiment, a groove 41 is provided on the top of the suspension seat 4, and a control motor 102 is fixedly connected to the groove 41. The output shaft of the control motor 102 is fixedly connected to a driving gear 1021 located below the suspension seat 4. The driving gear 1021 is meshed with the inner circumferential wall of the annular turntable 106, and a circle of teeth can be provided on the inner circumferential wall of the annular turntable 106. That is to say, the control motor 102 provides driving force for the rotation of the annular turntable 106 through the driving gear 1021.

[0052] A water spray pipe 105 is provided at the bottom of the suspension seat 4 near the inner circle of the annular turntable 106. The function of this water spray pipe 105 is to spray cleaning liquid downward. When the cloth cleaning disc 8 moves to the bottom of the water spray pipe 105, the cleaning liquid sprayed by the water spray pipe 105 will wet the short cloth rope 82, thereby realizing the function of replenishing water to the short cloth rope 82.

[0053] Furthermore, a water tank 103 is fixedly installed in the trough 41, and a water pump is installed in the water tank 103. The water outlet pipe of the water pump is fixedly connected to the transfer pipe 1031 located outside the water tank 103. The top of the water spray pipe 105 extends into the trough 41 and is connected to the transfer pipe 1031 through a hose. After the water pump is started, the cleaning liquid will be sprayed out through the water spray pipe 105.

[0054] Example 2

[0055] See also Figure 8-10, which is different from Example 1 in that the suspension rod 61 is an elastic telescopic structure and includes a base rod 6101, a tension spring 6102 and a sleeve 6103, one end of the sleeve 6103 is sleeved on the outside of the base rod 6101 and one side of the sleeve is fixedly connected to the vertical plate 62, the tension spring 6102 is located in the tension spring 6102 and its two ends are respectively fixedly connected to the base rod 6101 and the sleeve 6103, that is, the distance between the cloth cleaning disk 8 and the suspension shaft 5 can be adjusted, and the bottom of the suspension seat 4 is slidably connected to a driving disc 104, and a clearance notch 1041 for making way for the suspension shaft 5 is opened in the middle of the driving disc 104, and a roller 61031 is arranged on the other side of the sleeve 6103, and the outer peripheral wall of the roller 61031 and the driving disc 104 are connected to the driving disc 104. The outer peripheral walls of the disk 104 are against each other, and the adjustment of the above distance is controlled by the sliding of the driving disk 104. When the driving disk 104 moves, under the action of the track formed by its outer peripheral wall and the elastic tension of the tension spring 6102, the distance between the cloth cleaning disk 8 and the suspension shaft 5 will change. Therefore, when the lens 2 is located directly below the straight line of movement of the driving disk 104, the cloth cleaning disk 8 increases the squeezing force on the lens 2 when passing through the lens 2, and there is also a situation where the cloth cleaning disk 8 does not contact the lens 2. When the squeezing force between the cloth cleaning disk 8 and the lens 2 increases, it can clean up the dirt with stronger adhesion strength. When the cloth cleaning disk 8 does not contact the lens 2, it is convenient to centrifugally clean the sewage mixture on the short cloth rope 82. It should be noted that the change in the distance between the cloth cleaning disk 8 and the suspension shaft 5 will also change its rotation speed. Therefore, there is a way to clean the lens 2, which is to control the suspension 6 to continue to revolve, and then start the drive disc 104 to move so that the cloth cleaning disc 8 rotates and passes through the lens 2. When passing through, it will strongly squeeze the outer surface of the lens 2. At this time, when the cloth cleaning disc 8 and the lens 2 are relative, its rotation speed is at the lowest state. When the distance between the cloth cleaning disc 8 and the lens 2 is the largest, the rotation speed of the cloth cleaning disc 8 is the highest. Therefore, after water is supplied to the cloth cleaning disc 8 once, the variable speed revolution of the cloth cleaning disc 8 can effectively drain water centrifugally, clean up adhesions, water stains and water marks (on the lens 2 and the short cloth rope 82), and has the advantage of high cleaning efficiency of the lens 2.

[0056] Furthermore, a positioning groove 51 is formed on the outer wall of the suspension shaft 5, and an electric push rod 107 is arranged in the positioning groove 51. The back of the driving disc 104 is fixedly connected to a connecting plate 1042 fixedly connected to the output shaft of the electric push rod 107. The electric push rod 107 provides driving force for the sliding of the driving disc 104.

[0057] Working principle: When it is used, when it is necessary to clean the surface of the lens 2 from the adhered dirt, the suspension 6 is controlled to revolve, the cloth cleaning disc 8 is located below the water spray pipe 105, the water spray pipe 105 sprays water to wet the short cloth rope 82, and then the suspension 6 is controlled to rotate to the position where the short cloth rope 82 contacts the surface of the lens 2, and the annular turntable 106 is controlled to rotate. Under the transmission of the linkage transmission assembly 9, the small pulley 93 drives the rotating shaft 7 to rotate at a high speed, and the short cloth rope 82 is swung under the action of centrifugal force to clean the dirt on the lens 2. Under the action of centrifugal force, the short cloth rope 82 is separated from the sewage. When the humidity of the short cloth rope 82 is greatly reduced, the water stains and water marks on the lens 2 will gradually disappear, and the lens 2 is vigorously cleaned. Then the suspension 6 is controlled to rotate, the cloth cleaning disc 8 is located below the water spray pipe 105 again, the water spray pipe 105 sprays water for the second time, and then the annular turntable 106 is controlled to rotate to realize the centrifugal cleaning function of the cloth cleaning disc 8 itself, which is convenient for subsequent use.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
