[0015] Compared with the prior art, the present invention provides a lens cleaning device for outdoor 3D code scanning recognition, which has the following beneficial effects: 1. The lens cleaning device for outdoor 3D code scanning recognition drives the limit rod to move circumferentially in the sliding groove through a servo motor, so that the scraper only scrapes and cleans the mirror surface of the camera body in one direction with one side, which can avoid the problem that the scraper is stained with dust on both sides during the reciprocating cleaning process, resulting in some dust falling on the mirror surface of the camera body during the movement and cannot be completely cleaned.

The present invention drives the limit rod to make circumferential motion in the sliding groove through a servo motor, so that the scraper can only scrape and clean the mirror surface of the camera body in one direction with one side.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0023] Reference Figure 1-Figure 8 , including a camera body 1 and a bottom plate 2, the camera body 1 is fixed on the bottom plate 2, and also includes: a support column 22 is fixed on the bottom plate 2, and an upper support plate 21 is fixed above the support column 22; a sliding groove 23 is opened on the bottom plate 2 and the support column 22, a limited insertion rod 36 slides in the sliding groove 23, and a scraper strip 35 is fixed on the limited insertion rod 36; a rotating block 231 is plugged into the sliding groove 23 through a rotating shaft, and a torsion spring is connected between the sliding groove 23 and the rotating block 231; a fixed plate 34 is fixed on the limited insertion rod 36, a telescopic rod 33 is fixed on the fixed plate 34, and the other end of the telescopic rod 33 is fixedly connected to the extrusion plate 32, and a support block 38 and a servo motor 3 are respectively fixed on the upper support plate 21, and a threaded rod 31 is fixedly connected to the output end of the servo motor 3, the threaded rod 31 is rotatably connected to the support block 38, the threaded rod 31 is threadedly connected to the extrusion plate 32, and the bottom plate 2 is threadedly connected to the tripod bracket 11.

[0024] In the present invention, a plurality of bolt holes are provided on the bottom plate 2, and the camera body 1 is fixed to the base of the bottom plate 2 by bolts. The support column 22 and the upper support plate 21 are designed as an integrated unit, and the support column 22 and the bottom plate 2 are fixedly connected by bolts, and the bolts are all fixed by threaded connection from the bottom of the bottom plate 2, so that the user can disassemble, repair and replace the camera body 1 by bolts. The threaded rod 31 is driven to rotate by the servo motor 3, so that the extrusion plate 32 can be driven to reciprocate along the direction of the threaded rod 31, so that the extrusion plate 32 can drive the telescopic rod 33 and the limit plug rod 36 to move synchronously. The limit plug rod 36 is inserted into the sliding groove 23 on the upper support plate 21 and the bottom plate 2. The overall shape of the sliding groove 23 is a parallelogram, and there is an extended stop groove on the two long sides. A rotatable rotating block 231 is provided at the two acute-angled corners. A torsion spring is connected between the rotating block 231 and the bottom surface of the sliding groove 23, and the torsion spring makes the rotating block 231 always in Figure 5 When the limiting rod 36 enters the long side groove along the short side groove, the rotating block 231 will be pushed open and enter the stop groove. After the rotating block 231 is pushed open, it is controlled to close by the torsion spring, so that the limiting rod 36 can move along the long side groove after switching the moving direction, and then the extrusion plate 32 only needs to perform a lateral reciprocating motion to drive the limiting rod 36 to move along the sliding groove 23 as shown in FIG. Figure 2 The scraper 35 will be driven to clean the mirror surface of the camera body 1 when the limit rod 36 moves in the inner long side groove; the scraper 35 will not contact the mirror surface of the camera body 1, so that the scraper 35 will only clean the mirror surface of the camera body 1 with one side. Compared with the traditional reciprocating scraping cleaning, it can avoid the problem that the scraper 35 is stained with dust on both sides during the cleaning process, resulting in some dust falling on the mirror surface of the camera body 1 during the movement and unable to be completely cleaned.

[0026] Reference Figure 1-Figure 8 The piston cylinder 4 and the spring baffle 43 are fixed on the upper support plate 21, and a compression spring 44 is fixed on the spring baffle 43. The other end of the compression spring 44 is fixedly connected to the piston push rod 41. The piston push rod 41 slides in the piston cylinder 4. The upper support plate 21 is respectively fixed with a sliding frame 47 and a clamping plate 45. A sliding inclined block 46 slides in the sliding frame 47. A return spring 49 is connected between the sliding inclined block 46 and the sliding frame 47. A link rod 48 is fixed on the sliding inclined block 46. The link rod 4 8 slides on the sliding frame 47, the other end of the link rod 48 is fixedly connected to the reset plate 491, a water tank 7 is fixed above the upper support plate 21, a water inlet 71 is opened above the water tank 7, the water tank 7 is connected to the piston cylinder 4, the piston cylinder 4 is connected to the water supply pipe 42, a sliding rod 37 is fixed on the fixed plate 34, the other end of the sliding rod 37 is fixedly connected to the extrusion block 39, the sliding rod 37 passes through the extrusion plate 32, a water receiving trough 6 is fixed on the bottom plate 2, and the side wall of the water receiving trough 6 is connected to the drain pipe 61.

[0027] In the present invention, when the extrusion plate 32 moves laterally, it will drive the sliding rod 37 and the extrusion block 39 to move synchronously. When the extrusion plate 32 moves to one side of the piston cylinder 4, the limiting rod 36 will slide from the outer long side to the inner long side groove. At this time, the limiting rod 36 will drive the sliding rod 37 and the extrusion block 39 to move synchronously. The extrusion block 39 will push and squeeze the piston push rod 41, so that the cleaning liquid inside the piston cylinder 4 is sprayed onto the mirror surface of the camera body 1 through the water supply pipe 42. A plurality of foam nozzles are linearly arranged on the water supply pipe 42, so that the cleaning liquid can be sprayed onto the mirror surface of the camera body 1 in the form of foam, so that the coverage of the cleaning liquid is more uniform, thereby improving the cleaning effect. The connection between the water tanks 7 is provided with a one-way valve, so that the water in the water tank 7 can only transport the cleaning liquid to the piston cylinder 4 in one direction, and the cleaning liquid in the piston cylinder 4 can only transport the cleaning liquid to the water supply pipe 42 in one direction. The compression spring 44 is always in a compressed state, so that the piston push rod 41 can be pushed to reset after the piston push rod 41 loses the extrusion limit, and then the cleaning liquid can be quantitatively extracted from the water tank 7. Because the length of the short side groove is short, the feed amount of the extrusion block 39 alone may not be able to push the piston push rod 41 to extrude enough cleaning liquid. An inclined block can be fixed on the piston push rod 41, so that the piston push rod 41 can be pushed by the lateral movement of the extrusion block 39 to extrude the inclined block, further increasing the propulsion stroke of the piston push rod 41, so that a sufficient amount of cleaning liquid can be squeezed. When the piston push rod 41 is squeezed and pushed to the bottom by the squeezing block 39, the piston push rod 41 will squeeze the inclined surface of the sliding inclined block 46 to make the sliding inclined block 46 move backward. When the piston push rod 41 contacts the clamping plate 45, the sliding inclined block 46 loses its restriction, and the return spring 49 will push the sliding inclined block 46 to return to its original position, thereby completing the clamping and limiting of the piston push rod 41, so that the mirror surface of the camera body 1 will not be sprayed with liquid again in the next cleaning movement. A slider is provided on the piston push rod 41 to slide in the slide groove provided in the upper support plate 21, so that the piston push rod 41 can be limited to prevent the piston push rod 41 from rotating due to the squeezing force. The reset plate 491 slides in the slide groove provided in the upper support plate 21 through the slider extending from the top. The reset plate 491 is fixedly connected to the sliding inclined block 46 through the link rod 48, so as to move synchronously with the sliding inclined block 46. Figure 2As shown, the stay groove at the upper left corner of the sliding groove 23 is longer than that at the lower right corner, and the extended part is the same as the sliding stroke of the reset plate 491. Whenever cleaning is completed, the limit rod 36 will perform a reciprocating motion in the extended stay groove in the original stroke, thereby driving the extrusion block 39 to push the reset plate 491 to perform a reciprocating motion, and then the sliding inclined block 46 will perform a reciprocating motion, and then the limit of the sliding inclined block 46 on the piston push rod 41 will be released, and under the action of the compression spring 44, the piston push rod 41 will be reset to complete the extraction of the cleaning liquid in the water tank 7; The water tank 7 should be coated with a sunscreen coating and a heat-insulating coating to prevent the water tank 7 from being exposed to the outside world for a long time, which may cause the sunlight and high temperature to deteriorate the cleaning liquid in the water tank 7. The water tank 7 is arranged above the camera body 1 to protect the camera body 1 and prevent the camera body 1 from being damaged by being dropped or hit. Example

[0028] Reference Figure 1-Figure 8 , including a camera body 1 and a bottom plate 2, the camera body 1 is fixed on the bottom plate 2, and also includes: a support column 22 is fixed on the bottom plate 2, and an upper support plate 21 is fixed above the support column 22; a sliding groove 23 is opened on the bottom plate 2 and the support column 22, a limited insertion rod 36 slides in the sliding groove 23, and a scraper strip 35 is fixed on the limited insertion rod 36; a rotating block 231 is plugged into the sliding groove 23 through a rotating shaft, and a torsion spring is connected between the sliding groove 23 and the rotating block 231; a fixed plate 34 is fixed on the limited insertion rod 36, a telescopic rod 33 is fixed on the fixed plate 34, and the other end of the telescopic rod 33 is fixedly connected to the extrusion plate 32, and a support block 38 and a servo motor 3 are respectively fixed on the upper support plate 21, and a threaded rod 31 is fixedly connected to the output end of the servo motor 3, the threaded rod 31 is rotatably connected to the support block 38, the threaded rod 31 is threadedly connected to the extrusion plate 32, and the bottom plate 2 is threadedly connected to the tripod bracket 11.

[0029] Reference Figure 1-Figure 8 An airbag baffle 51 is fixed on the upper support plate 21 , a compressed airbag 5 is fixed on the airbag baffle 51 , an air pipe 52 and an air inlet 54 are respectively connected to the compressed airbag 5 , and a heating copper tube 53 is sleeved on the air pipe 52 .

[0030] In the present invention, a one-way air inlet valve is provided between the compressed air bag 5 and the air inlet hole 54, so that the compressed air bag 5 can absorb air through the air inlet hole 54 when it is compressed and restored. A one-way air outlet valve is provided between the air pipe 52 of the compressed air bag 5, so that the gas inside the compressed air bag 5 can be discharged through the air pipe 52 when it is squeezed. The air pipe 52 is provided with a plurality of linearly distributed blowing holes, so that the gas can evenly blow and clean the dust on the mirror surface of the camera body 1. The material of the air pipe 52 is a metal material with good thermal conductivity, so that when the heating copper tube 53 is started, the gas inside the air pipe 52 can be heated, and then the mirror surface of the camera body 1 can be dried by hot air. The extrusion plate 32 will squeeze the compressed air bag 5 during each reciprocating motion, so as to complete the extrusion and blowing operation.

[0031] When in use, the position where the limit rod 36 stays is Figure 2 The servo motor 3 is then started to move the extrusion plate 32 to the right. During the movement, the extrusion plate 32 will first squeeze the compressed air bag 5. The gas in the compressed air bag 5 will perform the first step of blowing and cleaning the mirror surface of the camera body 1 through the air pipe 52. Then the extrusion block 39 contacts the piston push rod 41 and pushes the piston push rod 41, so that the cleaning liquid in the piston cylinder 4 is sprayed onto the mirror surface of the camera body 1 through the water supply pipe 42. At this time, the limit rod 36 moves to the lower right corner of the sliding groove 23. Then the servo motor 3 moves in the opposite direction, driving the extrusion plate 32 and the limit rod 36 to move to the left. The scraper 35 scrapes and cleans the mirror surface of the camera body 1 and resets to the starting position. This is a cleaning process. When the servo motor 3 repeats the above During the operation process, the piston push rod 41 is squeezed and limited by the sliding inclined block 46, so that the operation of spraying cleaning liquid will not be triggered. At the same time, the heating copper tube 53 starts to heat, so that the subsequent sprayed air can heat and dry the water stains remaining on the mirror surface of the camera body 1. When the last cleaning is completed, the servo motor 3 will drive the limit plug 36 to extend to the left for a distance to the bottom of the stay groove and then reset, so that the extrusion block 39 squeezes the reset plate 491 to drive the sliding inclined block 46 to synchronously move to release the limit of the piston push rod 41, preparing for the next cleaning. If the operation of spraying cleaning liquid multiple times is required during the entire cleaning process, it is only necessary to control the servo motor 3 to additionally drive the extrusion plate 32 to perform the above-mentioned limit release operation during the resetting process. Example
