Description

[0001] The present invention relates to the technical field of geodetic surveying and mapping, and particularly to a surveying and mapping device for geographic information collection. Background Art
[0002] Surveying and mapping is an activity of measuring, collecting, expressing the shape, size, spatial position and its attributes of natural geographical elements or surface artificial facilities, and processing and providing the obtained data, information and results.
[0003] Most of the current surveying and mapping instruments are equipped with camera components for purposes such as image capture and recording, high-precision measurement, non-contact measurement, versatility and flexibility. However, for surveying and mapping instruments that need to be used for long-term monitoring, the traditional camera components are obviously not suitable for the environment. Since the surveying and mapping instruments need to work outdoors for a long time without supervision, the outermost glass lens of the traditional camera component is prone to dust contamination, which affects the measurement accuracy. And when working in rainy days, rainwater hanging on the glass lens will cause blurred image capture and unable to achieve data measurement and monitoring. Therefore, a surveying and mapping device for geographic information collection is proposed. Summary of the Invention

A rotating sleeve is coaxially rotatably connected to the connecting shaft. A cylindrical water-absorbing sponge is connected to the rotating sleeve. One end of the connecting shaft away from the slider is connected to a second straight rack. The second straight rack meshes with a second gear. A control unit is arranged on the outer wall of the housing for controlling the output rotation speeds of the electric telescopic cylinder and the motor on rainy days.
[0008] Preferably, the control unit includes a water-collecting block and a floating plate. A water-collecting groove is formed in the water-collecting block.

Specific Embodiments
[0024] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0025] Referring to Figure 1-8 as shown, a surveying device for geographic information collection includes a housing 1 and a cleaning mechanism 2. A plurality of feet 11 are connected to the bottom of the housing 1. A lens surveying port 12 is provided on the housing 1. A camera assembly 13 is installed on the inner wall of the housing 1 opposite to the lens surveying port 12. A partition board 14 is sealingly connected to the inner wall of the housing 1. The camera assembly 13 penetrates through the partition board 14 and is sealingly connected to the partition board 14. A main shaft 15 is rotatably connected to the side of the partition board 14 close to the lens surveying port 12. A circular light-transmitting plate 16 is coaxially connected to the main shaft 15. The cleaning mechanism 2 is installed in the housing 1 and is used for regularly cleaning the light-transmitting plate 16 and cleaning rainwater.
[0026] In this embodiment, the cleaning mechanism 2 includes a motor 21 and an electric telescopic cylinder 25. A mounting seat 211 is installed on the inner wall of the bottom of the housing 1, and the motor 21 is installed on the mounting seat 211. A gear ring 22 is coaxially connected to the outer ring of the light-transmitting plate 16. The output shaft of the motor 21 is coaxially connected to a first gear 23, and the first gear 23 meshes with the gear ring 22. A rotating shaft 24 is connected to the inner wall of the top of the housing 1, and the lower end of the rotating shaft 24 is connected to a rotating plate 241. One end of the bottom surface of the rotating plate 241 is rotatably connected to a cleaning roller 243, and the other end of the bottom surface of the rotating plate 241 is connected to a water scraping plate 244. A water scraping strip 245 is connected to the water scraping plate 244. The electric telescopic cylinder 25 is installed on the inner wall of the top of the housing 1, and the movable end of the electric telescopic cylinder 25 is connected to a first straight rack 251. A second gear 242 is coaxially connected to the rotating shaft 24, and the first straight rack 251 meshes with the second gear 242. The stroke of the telescopic movement of the electric telescopic cylinder 25 just enables the first straight rack 252 to drive the second gear 242 to rotate 180°.
[0027] In this embodiment, a slide rail 26 is installed on the inner wall of the top of the housing 1. A slider 261 is slidably connected to the slide rail 26. A connecting shaft 27 is connected to the slider 261. A rotating sleeve 271 is coaxially rotatably connected to the connecting shaft 27. A cylindrical water-absorbing sponge 272 is connected to the rotating sleeve 271. One end of the connecting shaft 27 away from the slider 261 is connected to a second straight rack 28, and the second straight rack 28 meshes with the second gear 242. A control unit is provided on the outer wall of the housing 1 for controlling the output rotation speeds of the electric telescopic cylinder 25 and the motor 21 on rainy days.
[0028] In this embodiment, the control unit includes a water collecting block 3 and a floating plate 34. A water collecting groove 31 is formed in the water collecting block 3. A groove 32 is formed at the bottom of the water collecting groove 31. A circular water flow hole 33 is formed at the center of the bottom of the groove 32. The floating plate 34 is slidably connected to the groove wall of the groove 32. A conical and inverted water blocking block 35 is connected to the center of the bottom of the floating plate 34. A plurality of communication holes 341 are formed in the floating plate 34. A cavity 36 is formed in the water collecting block 3. A conductive block 38 is slidably connected to the cavity 36. A conductive strip 37 is embedded in one side wall of the cavity 36. The conductive strip 37 and the conductive block 38 are electrically connected to the control circuits of the electric telescopic cylinder 25 and the motor 21 through wires. When the conductive strip 37 contacts the conductive block 38 to conduct electricity, the electric telescopic cylinder 25 will retract and the motor 21 will be powered on and started. At the same time, a separate circuit is also provided on the motor 21 to realize the function of being powered on and started regularly.
[0029] In this embodiment, magnets are embedded in both the floating plate 34 and the conductive block 38, and the two magnets attract each other magnetically. When the floating plate 34 is in the lowest position, the position where the conductive block 38 is located does not contact the conductive strip 37. A pair of limiting blocks are provided at the notch of the groove 32.
[0030] In this embodiment, the light-transmitting plate 16 is made of a colorless and transparent material, and glass or plastic can be used. The wiper strip 245 is made of nitrile rubber, which has excellent heat resistance, oil resistance, wear resistance and aging resistance, thereby increasing the service life of the wiper strip 245.
[0031] In this embodiment, a drain hole 29 is provided at the bottom of the housing 1.
[0032] The working process and principle of the present invention are as follows:
[0033] When in use, the entire surveying and mapping device is installed at an outdoor surveying and mapping point, and the surveying instrument is turned on for surveying work. At this time, the light-transmitting plate 16 will be in contact with the outside world as the protective lens of the camera assembly 13. External light is captured by the camera assembly through the lens surveying port 12 and the light-transmitting plate 16. After the surveying and mapping device has worked for a certain period of time, the timing circuit of the motor 21 will be turned on, causing the motor 21 to start working. The light-transmitting plate 16 is driven to rotate through the meshing transmission of the first gear 23 and the gear ring 22, and the light-transmitting plate 16 in the area where dust has adhered at the lens surveying port 12 is rotated away, and the light-transmitting plate 16 in the clean area is moved to the lens surveying port 12, realizing the timely update of the outermost lens of the camera assembly 13, ensuring the image capture quality of the camera assembly 13, maintaining good measurement accuracy, and the light-transmitting plate 16 in the area where dust has adhered contacts the cleaning roller 243 during the rotation process, realizing the cleaning of the dust on the light-transmitting plate 16.
[0034] When it is rainy, rainwater will fall on the light-transmitting plate 16 at the lens mapping port 12. At this time, the water collecting groove 31 of the water collecting block 3 will collect the dripping rainwater and converge it in the groove 32. In the initial stage of rain, the floating plate 34 is at the bottom of the groove 32. At this time, the diameter of the water blocking block 35 just blocks the flowing water hole 33, and the rainwater will accumulate in the groove 32. As the amount of rainwater in the groove 32 rises, the floating plate 34 will float upward, driving the conductive block 38 to slide upward in the cavity 36 by means of magnetic force to contact the conductive strip 37. The motor 21 will be powered on to drive the light-transmitting plate 16 to rotate, removing the area with adhered rainwater on the light-transmitting plate. At the same time, the electric telescopic cylinder 25 pulls the first straight rack 251 to retract. Through the meshing transmission between the first straight rack 251, the second gear 242 and the second straight rack 28, the rotating shaft 24 is driven to rotate 180°, switching the cleaning roller 243 to the wiper blade 244. At the same time, the push slider 261 is pushed to slide on the slide rail 26 to make the water-absorbing sponge 272 fit with the light-transmitting plate 16. During the rotation of the light-transmitting plate 16, most of the rainwater on the surface of the light-transmitting plate 16 will be scraped off by the scraping strip 245, and the remaining rainwater will be absorbed by the subsequent water-absorbing sponge 272, realizing the continuous cleaning of the rainwater on the light-transmitting plate 16 and ensuring the image capture clarity of the camera assembly 13.
[0035] When the rainfall increases, the water inflow of the water collecting groove 31 and the groove 32 will be greater than the drainage volume of the flowing water hole 33. The floating plate 34 will float upward again, and the conductive block 38 in the cavity 36 will be driven to slide upward by magnetic force. The conductive strip 37 is equivalent to a sliding rheostat. After the conductive block 38 slides upward, the resistance connected to the circuit will decrease, causing the current passing through the motor 21 to increase and the output speed of the motor 21 to increase, so that the rotation speed of the light-transmitting plate 16 is increased. Even in heavy rain, it can still maintain a relatively fast rotation and switching of the light-transmitting plate 16 area, reducing the impact of rainwater on the image capture of the camera assembly 13. At the same time as the floating plate 34 floats upward, the water blocking block 35 will also move upward, and the reduction of the water blocking volume increases the drainage volume of the flowing water hole 33. When the water inflow and the drainage volume reach a balance, the floating plate 34 will stabilize at a certain height. When the rainfall continues to increase, the floating plate 34 will continue to float upward, realizing the adjustment of the rotation speed of the light-transmitting plate 16 according to the rainfall amount.
[0036] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
