DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example 1

[0036] A surveillance camera with a cleaning function, such as Figure 1-3 As shown, it includes a mounting block 1, a connecting block 2, a servo motor 3, a rotating block 4, a camera body 5, a cleaning mechanism 6, a spraying mechanism 7 and a pushing mechanism 8. The mounting block 1 is rotatably connected to the connecting block 2, the connecting block 2 is rotatably connected to the rotating block 4, a servo motor 3 is installed on the right side of the connecting block 2, the output shaft of the servo motor 3 is rotatably connected to the connecting block 2, and is connected to the rotating block 4, a camera body 5 capable of real-time monitoring of indoor conditions is installed on the rotating block 4, a cleaning mechanism 6 for cleaning the lens is connected to the camera body 5, and a spraying mechanism 7 for spraying clean water to assist cleaning is connected to the camera body 5.

[0037] like Figure 1 and Figure 4As shown, the cleaning mechanism 6 includes a support block 61, a sliding frame 62, a compression spring 63, a fixed block 64, a turntable 65 and cleaning cotton 66. The support blocks 61 are symmetrically connected to the front of the camera body 5. The sliding frames 62 are slidably connected between the support blocks 61. Compression springs 63 are connected between the left and right sides of the sliding frame 62 and the adjacent support blocks 61. The lower part of the sliding frame 62 is connected to the fixed block 64, and the turntable 65 is rotatably connected to the fixed block 64. Cleaning cotton 66 for cleaning the lens is glued to the turntable 65. The cleaning cotton 66 moves upward to contact the lens of the camera body 5.

[0038] like Figure 1 , Figure 5 and Figure 6 As shown, the spraying mechanism 7 includes a storage cylinder 71, a threaded block 72, a connecting cylinder 73, an extrusion plate 74, a return spring 75 and a nozzle 76. The storage cylinder 71 for storing clean water is symmetrically fixed on the camera body 5. The storage cylinder 71 is made of transparent material to facilitate viewing of the remaining amount of clean water inside and timely addition. The top rear side of the storage cylinder 71 is threadedly connected with the threaded block 72, and the front side of the storage cylinder 71 is connected with the connecting cylinder 73. The connecting cylinder 73 is slidably connected with an extrusion plate 74 for squeezing clean water. The extrusion plate 74 and the adjacent connecting cylinder 73 are connected with a return spring 75. The upper part of the connecting cylinder 73 is connected with a nozzle 76 for spraying clean water. The connecting cylinder 73 is equipped with a one-way valve (not shown in the figure), and the sliding frame 62 is connected to the two extrusion plates 74.

[0039] like Figure 1 , Figure 7 and Figure 8 As shown, the pushing mechanism 8 includes an electric push rod 81, a connecting rod 82 and an inclined plate 83. The electric push rod 81 is installed on the top of the camera body 5. The connecting rod 82 is connected to the telescopic rod of the electric push rod 81. The inclined plate 83 is fixed on the connecting rod 82. The inclined plate 83 is attached to the top of the camera body 5, and the sliding frame 62 is in contact with the inclined plate 83.

[0040] The device can be installed for indoor and outdoor use, so as to monitor the indoor and outdoor conditions in real time. The camera body 5 can be connected to the circuit to start, so as to shoot the indoor conditions. The image will be transmitted to the mobile phone or computer for people to view. The servo motor 3 works according to the programming set in the control box. When using the device, the threaded block 72 can be unscrewed first, and clean water can be injected into the storage cylinder 71, and then flow into the connecting cylinder 73, which is convenient for later use. After the clean water is injected, the threaded block 72 is screwed back onto the storage cylinder 71, and then the mounting block 1 can be fixed to the height of the indoor wall by screws to fix the device. When the camera body 5 is working, the servo motor 3 will be controlled to operate through the control box. The output shaft of the motor 3 rotates to drive the rotating block 4 and the camera body 5 to rotate upward or downward, and then drives the cleaning mechanism 6 and the spraying mechanism 7 to rotate as a whole. The servo motor 3 will run forward and reverse according to the set programming, so that the camera body 5 rotates at a uniform speed, and the indoor situation is photographed more clearly. When the device is installed, the connecting block 2 can also rotate along the mounting block 1, and the camera body 5 can be rotated and adjusted in two directions. Initially, the angle can be adjusted according to the installation position of the camera body 5 to avoid many blind spots. When the device is used for a long time, the lens on the camera body 5 is prone to more dust. At the same time, due to the temperature, water mist is easily generated on the lens, and dust will stick to the water mist. When it is necessary to clean the dust, the telescopic rod of the electric push rod 81 can be controlled to retract from the initial extended state, thereby driving the connecting rod 82 and the inclined plate 83 to move backward, so that the inclined plate 83 pushes the sliding frame 62 to move upward, and the compression spring 63 is compressed accordingly, and the sliding frame 62 drives the fixed block 64, the turntable 65 and the cleaning cotton 66 to move upward. The sliding frame 62 also drives the squeezing plate 74 to move upward, so that the return spring 75 is compressed. The squeezing plate 74 moves upward to squeeze the cleaning water in the connecting tube 73, so that the cleaning water is sprayed onto the lens of the camera body 5 through the nozzle 76. Because a one-way valve is installed in the connecting tube 73, the water will not flow back into the storage tube 71. The cleaning cotton 66 moves upward to contact the lens, and then the lens is wiped clean. After the telescopic rod of the electric push rod 81 is retracted, the telescopic rod of the electric push rod 81 will automatically extend and reset, so that the telescopic rod of the electric push rod 81 extends and drives the connecting rod 82 and the inclined plate 83 to move backward and reset, and the inclined surface no longer blocks the sliding frame 62. The sliding frame 62 will drive the fixed block 64, the turntable 65 and the cleaning cotton 66 to move downward and reset under the reset action of the compression spring 63. The sliding frame 62 then drives the squeezing plate 74 to move downward and reset, so that the return spring 75 is reset, and the squeezing plate 74 will also pump the cleaning water in the storage tube 71 into the connecting tube 73 for the next use. In this way, under the action of the spraying mechanism 7, when cleaning the lens, the cleaning water can be automatically sprayed out, so that the lens is cleaned more cleanly and dirt is avoided.

[0041] Example 2

[0042] On the basis of Example 1, Figure 1 and Fig. 9 As shown, a defogger mechanism 9 is also included. The defogger mechanism 9 includes fixed columns 91 and heating wires 92. The fixed columns 91 are evenly fixed along the circumferential direction on the inner front side of the camera body 5. The heating wires 92 are connected between the fixed columns 91. The heating wires 92 are located inside the camera body 5.

[0043] In humid weather, water mist is easily generated on both sides of the lens of the camera body 5. The heating wire 92 can be turned on to generate heat, thereby putting the lens in a high temperature environment, which can evaporate the moisture on the lens and achieve the purpose of cleaning. After the water mist is cleaned, the heating wire 92 is turned off. In this way, there is no need to clean the lens specifically. For some small water mist, it can be directly removed by heating with the heating wire 92.

[0044] like Figure 1 , Fig.10 and Fig.11 As shown, it also includes a rotating mechanism 10, which includes a support rod 101, a pull rope 102 and a torsion spring 103. The support rod 101 is fixed to the front bottom side of the camera body 5, and a torsion spring 103 is connected between the turntable 65 and the fixed block 64. A pull rope 102 is wound around the turntable 65 and can indirectly rotate the cleaning cotton 66. The lower end of the pull rope 102 is connected to the support rod 101.

[0045] When cleaning the lens, the sliding frame 62 moves upward with the fixing block 64, the rotating disk 65 and the cleaning cotton 66, and the pull rope 102 will also move upward. Because the lower end of the pull rope 102 is connected to the support rod 101, the support rod 101 will pull the pull rope 102, so that the pull rope 102 moves up and is stretched along with the rotating disk 65, and the pull rope 102 drives the rotating disk 65 and the cleaning cotton 66 to rotate, so that the torsion spring 103 is deformed, and the cleaning cotton 66 rotates to fully contact and wipe the lens, and the cleaning effect is better. After cleaning, the sliding frame 62 moves downward with the fixing block 64, the rotating disk 65 and the cleaning cotton 66 to reset, and the pull rope 102 will also move downward to relax the pull rope 102, and the rotating disk 65 will drive the cleaning cotton 66 to rotate in the opposite direction under the resetting action of the torsion spring 103, and then drive the pull rope 102 to reverse, and the pull rope 102 can be reeled up. In this way, under the action of the rotating mechanism 10, it can automatically rotate when the cleaning cotton 66 cleans the lens, so as to achieve a better cleaning effect.

[0046] like Figure 1 and Fig.12As shown, it also includes an adjustment mechanism 11, which includes a drive motor 111 and a gear 112. The drive motor 111 capable of adjusting the angle of the camera body 5 is fixed to the lower part of the mounting block 1, and the gear 112 is fixed to the output shaft of the drive motor 111 and the rear side of the connecting block 2, and the two gears 112 are meshed with each other.

[0047] When using this device, the driving motor 111 can also be controlled by the control box. When the driving motor 111 runs forward or reverse, the output shaft rotates, which will drive the connecting block 2 to rotate along the mounting block 1 through the two gears 112, and then the rotating block 4, the servo motor 3 and the camera body 5 can be rotated, and the angle of the camera can be adjusted. After the adjustment, the driving motor 111 can be turned off.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
