It quickly obtains the spatial point position information on the surface of the measured object through the method of high-speed laser scanning measurement, and has measurement advantages such as non-contact, automation, and high efficiency. Among them, the handheld slam laser scanner is not restricted by the environment during operation and has relatively high scanning accuracy, and has broad application prospects in the surveying and mapping field. During the use of the slam laser scanner, when water enters the inside of the slam laser scanner, it will cause equipment failures, and when rainwater adheres to the scanner, it will also affect the propagation of the laser, thereby affecting the scanning quality. Moreover, the slam laser scanner itself does not have any protective structure. Therefore, when using the slam laser scanner to collect information during building scanning and surveying on less rainy days, the accuracy of information collection cannot be well guaranteed, and at the same time, the service life of the equipment cannot be well guaranteed. Therefore, an information collection device for building surveying and mapping is proposed for the above problems. Content of the Utility Model

The right side of the bottom end of the rain shield 5 is fixedly connected with a storage battery 19 and a controller 20 arranged horizontally.

[0022] Embodiment 2

[0023] As Figures 2-3 shown, to solve the problem that it is not convenient to control the scraping rod 10 to scrape the rainwater on the rain shield 5, a worm gear 6 is fixedly connected to the outside of the sleeve shaft 4, a worm 7 is meshed and connected to the outside of the worm gear 6, and one end of the worm 7 is fixedly connected to a motor 8 fixedly connected to the fixed block 2. By controlling the motor 8 to drive the worm 7 to mesh with the worm gear 6, and further driving the rain shield 5 to rotate through the sleeve shaft 4 and slide with the scraping rod 10, it is convenient to control the scraping rod 10 to scrape the rainwater on the rain shield 5.

[0024] Embodiment 3

[0025] As Figures 1-3 shown, to solve the problem that the scraping effect of the scraping rod 10 on the rainwater outside the rain shield 5 is poor, a rectangular parallelepiped-shaped limiting block 21 is fixedly connected to the top end of the fixed shaft 3, a fixed sleeve 11 slidably connected to the fixed shaft 3 is slidably connected to the outside of the limiting block 21, and a first spring 12 is arranged at the top end outside the fixed shaft 3, and the first spring 12 is fixedly connected to the limiting block 21 and the fixed sleeve 11. By making the fixed rod 9 drive the rubber scraping rod 10 to be in close contact with the rain shield 5 under the elastic force of the first spring 12 on the fixed sleeve 11, when controlling the scraping rod 10 to scrape the rainwater on the rain shield 5, the scraping effect of the rainwater outside the rain shield 5 is better.

[0026] Embodiment 4

[0027] As Figure 1 、 Figure 2 and Figure 4 shown, to solve the problem that it is not convenient to replace the aging rubber scraping rod 10, a threaded shaft 13 penetrating through the fixed rod 9 is spirally connected to the top end of the fixed rod 9, a pressing rod 14 rotatably connected to the bottom end of the threaded shaft 13 and slidably connected to the fixed rod 9 is in contact with the scraping rod 10. By rotating the threaded shaft 13 to be spirally connected to the fixed rod 9, and further controlling the pressing rod 14 to slide up and no longer press the scraping rod 10, it is convenient to draw out the aging scraping rod 10 from the right side of the fixed rod 9 for replacement.

[0028] Embodiment 5

[0029] As Figure 3As shown in the figure, to solve the problem that it is not convenient to install the protection mechanism on the top of the SLAM laser scanner 1, fixing plates 15 are fixedly connected to both the front and rear sides of the top end of the SLAM laser scanner 1. A clamping rod 16 passing through the fixing plate 15 is slidably connected to the inner side of the fixing plate 15, and the clamping rod 16 is engaged with the fixing block 2. One end of the outer side of the clamping rod 16 is fixedly connected to a sliding plate 17 slidably connected to the fixing plate 15. A second spring 18 is provided at the other end of the outer side of the clamping rod 16, and the second spring 18 is fixedly connected to the sliding plate 17 and the fixing plate 15. By pulling the clamping rod 16 to compress the second spring 18 with the sliding plate 17, then placing the fixing block 2 in the protection mechanism between the two fixing plates 15, and then releasing the pull on the clamping rod 16 to make the clamping rod 16 engage with the fixing block 2 in the protection mechanism, it is convenient to install the protection mechanism on the top of the SLAM laser scanner 1.

[0030] In this embodiment, when the device is used in light rain weather, pull the clamping rod 16 to compress the second spring 18 with the sliding plate 17, then place the fixing block 2 in the protection mechanism between the two fixing plates 15, and then release the pull on the clamping rod 16 to make the clamping rod 16 engage with the fixing block 2 in the protection mechanism. At this time, it is convenient to install the protection mechanism on the top of the SLAM laser scanner 1. When the device is used after installation, start the device through the controller 20. At this time, the rain shield 5 on the top of the SLAM laser scanner 1 will block the rain. At the same time, the motor 8 will also drive the worm 7 to engage with the worm gear 6, so as to drive the rain shield 5 made of transparent plastic to rotate through the sleeve shaft 4. Because at this time the fixed rod 9 drives the rubber scraping rod 10 to contact the rain shield 5 under the elastic force of the first spring 12 on the fixed sleeve 11, during the rotation of the rain shield 5, the scraping rod 10 will continuously scrape the rain falling outside the rain shield 5, thus preventing rainwater from entering the device and causing a failure of the SLAM laser scanner 1, and at the same time ensuring the accuracy of information collection of the SLAM laser scanner 1 when the device is used in light rain weather. Since the scraping rod 10 will age after long-term use, resulting in a poor scraping effect of the rain outside the rain shield 5, at this time, by rotating the threaded shaft 13 screwed to the fixed rod 9, further control the sliding plate 14 to slide up and no longer press the scraping rod 10, and the aging scraping rod 10 can be pulled out from the right side of the fixed rod 9 for replacement.
