Description

Technical Field

[0001] The present application relates to the field of surveying and mapping, and in particular to an integrated surveying and mapping reflection device. Background Art

[0002] In the field of surveying and mapping, total stations are commonly used for engineering surveying, including distance, angle, three-dimensional coordinate, and traverse measurements. A total station, short for total station electronic tachometer, is an optoelectronic instrument that combines an electronic theodolite, a photoelectric rangefinder, and a microprocessor. When measuring distance, the total station must be aimed at the center of a reflective prism and transmit and receive signals to obtain distance values. With the rapid development of lidar technology in recent decades, many engineering surveys now use laser scanners. Laser scanners transmit and receive laser light reflected from a target object to obtain three-dimensional environmental information. Compared to total stations, laser scanners offer high measurement density, high speed, and the absence of a reflective prism for signal reflection, thus garnering increasing attention. However, due to the scattered and disordered nature of lidar point clouds, the point cloud data collected by lidar is less reliable and accurate. Furthermore, due to errors in lidar system integration, cumulative errors often occur during the data acquisition process. This necessitates that large-scale point cloud data be collected in batches, which then require further processing (such as registration and adjustment) to obtain complete data. Therefore, total stations and lidar scanners each have their own advantages and disadvantages.

[0003] In actual engineering surveying, the two are often combined. A LiDAR scanner is used to obtain complete three-dimensional environmental information. A reflective prism is then installed in an appropriate area. The reflective prism is mounted on a centering pole via a prism pole, which is then mounted on the ground. The reflective prism reflects the surveying light, which is then scanned and received by a total station to obtain precise point position information. This information is used to assist in the registration of the LiDAR point cloud, eliminating accumulated errors and obtaining high-precision point cloud data. This step typically includes the following steps: first, reflective sheets are placed in the measurement area and scanned with a laser scanner to obtain point cloud data. Then, the reflective sheet area is located in the data area, and a reflective prism is again installed at its location. The total station is used to measure and obtain high-precision point positioning data. Finally, the total station point data is used to assist in the registration of the point cloud data, improving the average accuracy and quality of the point cloud data.

[0004] However, in existing surveying and mapping, reflective prisms and reflective sheets are deployed separately, making it difficult to ensure the relative positional consistency between different sets of reflective prisms and reflective sheets. This leads to certain errors in this measurement method. Furthermore, this measurement method requires finding the reflective sheet area in the point cloud data and deploying the reflective prisms, resulting in a complex workflow and a significant workload when measuring multiple points. These complex steps also introduce additional errors. Summary of the Invention

[0005] In order to improve the problem of complex process of arranging reflective prisms and reflective sheets in the surveying and mapping process in the prior art, the integrated surveying and mapping reflective device provided in this application adopts the following solution:

[0006] An integrated surveying and mapping reflection device is characterized in that it includes a mounting part, a reflecting prism, and a reflecting sheet, wherein the reflecting prism and the reflecting sheet are both mounted on the mounting part; the reflecting sheet is provided with a reflecting surface for reflecting surveying and mapping light, and the reflecting prism has a mirror surface for reflecting surveying and mapping light; the mounting part includes a prism rod for connecting to a centering rod, the orthogonal projection of the axis of the prism rod on the reflecting surface forms a centering line, the orthogonal projection of the center of the mirror surface on the reflecting surface and the center of the reflecting surface are both located on the centering line, and the reflecting surface and the mirror surface have the same orientation.

[0007] By adopting the above solution, the present application effectively simplifies the process of laying out the reflective prism and reflective sheet during the surveying and mapping process by using the technical means of installing the reflective prism and reflective sheet on the same mounting member. Traditional technical solutions usually require laying out the reflective prism and reflective sheet in two separate steps during the surveying and mapping process. After the surveyor has laid out the reflective sheet and completed the surveying and mapping, the surveyor needs to re-lay out the reflective prism and measure again, which is a large workload. Furthermore, the point cloud data obtained by the reflective sheet needs to be matched with the point positioning data obtained by the reflective prism, which inevitably leads to data errors. In the technical solution of the present application, by installing the reflecting prism and the reflecting sheet on the same mounting part, on the one hand, the surveying and mapping reflecting device formed by the combination has both the reflecting sheet and the reflecting prism, and the same device can achieve multi-functions; on the other hand, the reflecting sheet and the reflecting prism on the mounting part have the same orientation, and the center of the mirror surface and the center of the reflecting surface are both located on the projection of the axis of the reflecting prism on the reflecting surface, which ensures the centering effect of the surveying and mapping reflecting device, and the distance between the reflecting prism and the reflecting sheet is known. Therefore, during the surveying and mapping process, the surveying and mapping personnel only need to set up the surveying and mapping reflecting device once, and only need to directly substitute the known distance between the reflecting prism and the reflecting sheet into the subsequent calculation to complete the surveying and mapping, which significantly simplifies the surveying and mapping process for the layout of the reflecting prism and the reflecting sheet, and improves the surveying and mapping efficiency; thirdly, since there is no need to manually find the layout position of the reflecting sheet and layout the reflecting prism again, the unavoidable operational errors during the period can also be effectively eliminated, which helps to improve the accuracy of the surveying and mapping results.

[0008] Optionally, the mounting component also includes a mounting box body and a mounting cover plate, the reflective prism is installed in the mounting box body, the mounting box body has a reflective opening for mapping the entry and exit of light, and the mounting cover plate is hinged on the side edge of the mounting box body on one side of the reflective opening; the mounting cover plate is provided with a cover plate inner wall for resisting and covering the reflective opening, and the reflective sheet is fixed on the inner wall of the mounting cover plate.

[0009] By adopting the above-mentioned solution, the technical solution of the present application can close the mounting cover so that the reflecting prism and the reflecting sheet are covered and protected by the mounting member, which effectively prevents the reflecting prism and the reflecting sheet from being scratched. In the traditional technical solution, after the surveying is completed, the reflecting prism and the reflecting sheet are usually stored in an additional storage box to protect the reflecting prism and the reflecting member; however, this technical means, on the one hand, requires the surveyor to carry an additional storage box, which is inconvenient to carry; on the other hand, even if the reflecting prism and the reflecting sheet are stored in the storage box, the reflecting prism or the reflecting mirror may move in the storage box and be damaged by collision during transportation. In the technical solution of the present application, after the surveying is completed, the reflecting prism and the reflecting sheet can be stored for protection by simply closing the cover, which effectively simplifies the process and is easy to carry; on the other hand, since the reflecting prism and the reflecting mirror themselves are respectively mounted on the mounting box body and the mounting cover, the movement of the above two is restricted after the cover is closed, which effectively reduces the situation where the reflecting sheet or the reflecting prism is damaged by collision.

[0010] Optionally, the reflecting prism is rotatably mounted in the mounting box, the reflecting prism includes a mirror for reflecting surveying light, and the end face of the reflecting prism opposite to the mirror is covered with a soft buffer pad; the mounting cover has a closed state in which it contacts the reflecting opening, and in the closed state, the reflecting sheet is pressed against the soft buffer pad.

[0011] By adopting the above solution, the technical solution of the present application is provided with a soft cushion that can press against the reflective sheet, thereby further protecting it. During the storage and transportation of the reflective prism and the reflective sheet, due to unavoidable bumps and collisions caused by the external environment, the installation of the reflective sheet is usually unstable, and there is a possibility that the reflective sheet may fall off due to collisions. The technical solution of the present application provides a cushion on the back of the reflective prism. After the surveying and mapping is completed and the reflective prism is stored, the reflective prism can be rotated so that the cushion presses against the reflective sheet. This technical means effectively prevents the reflective sheet from falling off and being damaged, further protecting the reflective sheet.

[0012] Optionally, the mounting cover plate further has an open state in which it is engaged with the prism rod. An elastic slot is provided on the end face of the mounting cover plate opposite to the inner wall of the cover plate, and the prism rod is engaged in the elastic slot in the open state.

[0013] By adopting the above solution, the technical solution of the present application uses an elastic card slot to connect to the prism rod, which fixes the mounting cover to the prism rod when the cover is open, thereby positioning the reflector on the mounting cover. In actual production conditions, the mounting cover is affected by environmental factors such as wind, which may be disturbed and cause the reflector to move slightly, which can easily lead to measurement data errors. The technical solution of the present application can effectively improve the stability of the reflector when the cover is open during the surveying and mapping process, further improving the accuracy of the surveying and mapping data.

[0014] Optionally, the prism rod includes an upper support rod for connecting to the mounting box body and a lower support rod for connecting to the centering rod, one axial end of the upper support rod is hinged to one axial end of the lower support rod, and the other axial end of the upper support rod is hinged to the mounting box body. The upper support rod and the lower support rod are capable of rotatably fitting against the outer wall of the mounting box body.

[0015] By adopting the above-mentioned solution, the technical solution of the present application forms a prism rod by hingedly connecting the upper support rod and the lower support rod, which can be folded and stored after the surveying and mapping is completed to save space. In traditional technical solutions, the prism rod is usually detachably mounted on the reflective prism. After the surveying and mapping is completed, the surveyor needs to manually remove it for storage, and the next time the surveying and mapping is needed, the prism rod needs to be manually installed, and the operation process is relatively complicated. In the technical solution of the present application, the upper support rod is hinged on the installation box body, and the lower support rod is hinged to the upper support rod. When surveying and mapping work is required, the prism rod can be unfolded for use. After the surveying and mapping is completed, only the upper support rod and the lower support rod need to be rotated to fit on the outer wall of the installation box body. The operation process is relatively simple.

[0016] Optionally, a clamping portion is provided on the lower support rod, and a clamping groove is provided on the installation cover corresponding to the clamping portion; when the cover is closed, the lower support rod is attached to the outer wall of the installation box body and the clamping portion is clamped in the clamping groove.

[0017] By adopting the above solution, the technical solution of the present application is stably attached to the installation box body through the clamping portion on the lower support rod, and the installation cover is locked with the installation body, effectively preventing the installation parts from being disturbed during transportation, which causes the installation cover and the installation box body to rotate relative to each other. In the actual working conditions of storing and transporting the surveying and mapping reflection device, the installation cover may be bumped or flipped, causing the installation cover in the closed state to rotate away from the installation box body, thereby making it impossible to protect the reflective sheet and the reflective prism, and the reflective prism and the reflective sheet may be scratched and damaged. In the technical solution of the present application, the lower support rod is folded and attached to the outer wall of the installation box body, and the rotation of the installation cover can be limited by the clamping portion. On the one hand, the stability of the prism rod attached to the installation box body is ensured; on the other hand, the stability of the closed cover during transportation is effectively ensured, further improving the protection effect of the reflective sheet and the reflective prism.

[0018] Optionally, a limiting member for limiting the rotation of the mounting cover and the prism rod is provided in the mounting box body, and an opening and closing member for limiting the entry and exit of the limiting member in the box body is also slidably provided in the mounting box body; when the cover is closed, the opening and closing member is closed and the limiting member is received in the mounting box body; when the cover is open, the opening and closing member is opened and the prism rod and the mounting cover are respectively connected to the mounting box body through the limiting member.

[0019] By adopting the above-mentioned solution, the technical solution of the present application, by providing a limiter and an opening and closing member, can limit the rotation of the mounting cover plate and the prism rod when the surveying and mapping reflective device is in the open state, making the position of the reflective sheet on the mounting cover plate relatively stable and effectively ensuring the stability of the prism rod. In actual surveying and mapping, when the surveying and mapping reflective device is in the open state, because the prism rod is a foldable structure and the mounting cover plate is also rotatably mounted on the mounting box body, the cover plate may be disturbed and slightly move, and the prism rod may also be subjected to force and rotate, resulting in instability, making it difficult to ensure the position of the cover plate and the stability of the prism rod. In the technical solution of the present application, by providing a limiter, when the cover is in the open state, the opening and closing member opens to allow the limiter to limit the rotation of the mounting cover plate and the prism rod, effectively preventing the cover plate from slightly moving, thereby ensuring the position of the reflective sheet stable and further improving the accuracy of the surveying and mapping results. On the other hand, the prism rod can remain stable after being unfolded due to the limiter, further ensuring the stability and accuracy of the surveying and mapping.

[0020] Optionally, the limiting member includes a first pin, a second pin and a third pin, the upper support rod is provided with a first channel, the lower support rod is provided with a first blind hole for aligning with the first channel, and when the cover is open, one end of the first pin is located in the first blind hole, and the other end of the first pin is located in the first channel; a second blind hole is also provided in the upper support rod, and when the cover is open, one end of the second pin is located in the second blind hole, and the other end of the second pin is located in the installation box body; a third blind hole is provided on the installation cover plate, and when the cover is open, one end of the third pin is located in the third blind hole, and the other end of the third pin is located in the installation box body.

[0021] By adopting the above-mentioned scheme, the present application provides a first channel in the upper support rod and a corresponding first blind hole in the lower support rod. In actual surveying and mapping conditions, the prism rod is usually rotated and unfolded first, and then the first pin shaft located in the mounting box body can slide into the first channel as the opening and closing part is opened, and is resisted by the bottom surface of the first blind hole and is simultaneously located in the first blind hole and the first channel, thereby realizing the rotation limit between the upper support rod and the lower support rod; similarly, the limit member can also limit the upper support rod and the mounting box body, and between the mounting box body and the mounting cover plate; the technical solution of the present application drives the limit member by gravity, and does not require an additional driving source for driving. On the one hand, it further simplifies the operating process, and on the other hand, it does not require an additional driving source, which has the effect of energy saving and environmental protection.

[0022] Optionally, the opening and closing member is provided with a rope for pulling the opening and closing member to open and a return spring for driving the opening and closing member to slide closed; one end of the opening and closing member is fixed to the inner wall of the mounting cover through the rope, and the other opposite end of the opening and closing member is installed in the mounting box body through the return spring.

[0023] By adopting the above-mentioned scheme, the technical scheme of the present application drives the movement of the opening and closing parts through the pull rope and the return spring, and the opening and closing parts open and close as the installation cover is opened and closed, which significantly simplifies the work process; the technology of the present application adopts the technical means that the opening and closing parts move with the installation cover, and when the cover is closed, the opening and closing parts are closed to prevent the limiting parts from falling off from the installation box body; and when the cover is open, the opening and closing parts can be opened in a linkage manner to limit the prism rod and the installation cover; the design of the linkage structure of the technical scheme of the present application does not require additional operating procedures to limit the rotation of the prism rod and the installation cover, which significantly simplifies the operating process and effectively improves the layout efficiency of the surveying and mapping reflection device.

[0024] In summary, this application has at least the following beneficial technical effects:

[0025] 1. This application effectively simplifies the deployment of reflective prisms and reflective sheets during surveying and mapping by installing them on the same mounting fixture. Traditional solutions typically require deploying the reflective prism and reflective sheet separately in two separate steps during surveying and mapping. After surveyors deploy the reflective sheet and complete the survey, they must re-deploy the reflective prism and conduct another measurement, which is a significant workload. Furthermore, the point cloud data obtained from the reflective sheet must be aligned with the point positioning data obtained from the reflective prism, which inevitably results in data errors. In the technical solution of the present application, by installing the reflecting prism and the reflecting sheet on the same mounting part, on the one hand, the surveying and mapping reflecting device formed by the combination has both the reflecting sheet and the reflecting prism, and the same device can achieve multi-functions; on the other hand, the reflecting sheet and the reflecting prism on the mounting part have the same orientation, and the center of the mirror surface and the center of the reflecting surface are both located on the projection of the axis of the reflecting prism on the reflecting surface, which ensures the centering effect of the surveying and mapping reflecting device, and the distance between the reflecting prism and the reflecting sheet is known. Therefore, during the surveying and mapping process, the surveying and mapping personnel only need to set up the surveying and mapping reflecting device once, and only need to directly substitute the known distance between the reflecting prism and the reflecting sheet into the subsequent calculation to complete the surveying and mapping, which significantly simplifies the surveying and mapping process for the layout of the reflecting prism and the reflecting sheet, and improves the surveying and mapping efficiency; thirdly, since there is no need to manually find the layout position of the reflecting sheet and layout the reflecting prism again, the unavoidable operational errors during the period can also be effectively eliminated, which helps to improve the accuracy of the surveying and mapping results.

[0026] 2. The technical solution of the present application can close the mounting cover so that the reflecting prism and the reflecting sheet are covered and protected by the mounting part, which effectively prevents the reflecting prism and the reflecting sheet from being scratched. In the traditional technical solution, after the surveying is completed, the reflecting prism and the reflecting sheet are usually stored in an additional storage box to protect the reflecting prism and the reflecting part; however, this technical means, on the one hand, requires the surveying personnel to carry an additional storage box, which is inconvenient to carry; on the other hand, even if the reflecting prism and the reflecting sheet are stored in the storage box, the reflecting prism or the reflecting mirror may move in the storage box and be damaged by collision during transportation. In the technical solution of the present application, after the surveying is completed, the reflecting prism and the reflecting sheet can be stored for protection by simply closing the cover, which effectively simplifies the process and is easy to carry; on the other hand, since the reflecting prism and the reflecting mirror themselves are respectively mounted on the mounting box body and the mounting cover, the movement of the above two is restricted after the cover is closed, which effectively reduces the situation where the reflecting sheet or the reflecting prism is damaged by collision.

[0027] 3. The technical solution of the present application drives the movement of the opening and closing parts through a pull rope and a return spring. The opening and closing parts open and close as the installation cover is opened and closed, which significantly simplifies the work process. The technology of the present application adopts the technical means that the opening and closing parts move with the installation cover. When the cover is closed, the opening and closing parts are closed to prevent the limiting parts from falling off from the installation box body. When the cover is open, the opening and closing parts can be opened in a linkage manner to limit the prism rod and the installation cover. The design of the linkage structure of the technical solution of the present application does not require additional operating procedures to limit the rotation of the prism rod and the installation cover, which significantly simplifies the operating procedures and effectively improves the layout efficiency of the surveying and mapping reflection device.

[0041] The present application is further described in detail below with reference to the accompanying drawings.

[0042] Reference Figure 1 , an integrated surveying and mapping reflection device, which includes: a mounting part 1, a reflecting prism 2 for reflecting light in conjunction with a total station surveying and mapping, and a reflecting sheet 3 for reflecting light in conjunction with a laser radar scanner surveying and mapping, the reflecting prism 2 and the reflecting sheet 3 are both mounted on the mounting part 1.

[0043] Reference Figure 1 and Figure 2 The mounting member 1 includes a mounting box body 12, a mounting cover plate 13 and a prism rod 11. The mounting box body 12 has an accommodating chamber for installing the reflecting prism 2. The reflecting prism 2 is rotatably mounted in the accommodating chamber. The accommodating chamber has a reflecting opening 121 for measuring the entry and exit of light. In the embodiment of the present application, a rotating base is installed in the accommodating chamber, and the reflecting prism 2 is rotatably mounted on the rotating base. It is worth mentioning that in the embodiment of the present application, there is damping between the reflecting prism 2 and the rotating base. The reflecting prism 2 can stop at any rotation angle of the rotating base when not affected by external force to facilitate the adjustment of the reflecting prism 2. In other embodiments, a positioning protrusion is further provided on the end face of the rotating base close to the reflecting prism 2, and a positioning hole is provided on the reflecting prism 2 corresponding to the positioning protrusion, so that the positioning protrusion can be accommodated when the positioning hole of the reflecting prism 2 is rotated to be aligned with the positioning protrusion, thereby achieving positioning of the rotation angle of the reflecting prism 2; in this embodiment, when the mirror surface 21 of the reflecting prism 2 is facing the reflecting opening 121 or the end face opposite to the mirror surface 21 on the reflecting prism 2 is aligned with the reflecting opening 121, the positioning protrusion is received in the corresponding positioning hole to achieve positioning.

[0044] One side edge of the mounting cover 13 is hingedly connected to the side edge of the mounting box body 12 on one side of the reflective opening 121. The mounting cover 13 has an inner wall for contacting and covering the reflective opening 121, and the reflective sheet 3 is fixedly mounted on the inner wall of the cover. The mounting cover 13 has a closed state in which it contacts the reflective opening 121, and an open state in which it is engaged with the prism rod 11. In the closed state, the inner wall of the cover contacts the mounting box body 12 at the outer periphery of the reflective opening 121, and the reflective opening 121 is completely covered by the mounting cover 13, so that the reflective sheet 3 mounted on the inner wall of the cover is covered and protected by the mounting box body 12 and the mounting cover 13. At the same time, the reflective prism 2 mounted in the accommodating chamber is covered and protected by the mounting box body 12 and the mounting cover 13.

[0045] Reference Figure 2 and Figure 3An elastic card groove 131 is provided on the end face of the mounting cover 13 opposite to the inner wall of the cover. In the embodiment of the present application, the diameter of the elastic card groove 131 is not larger than the diameter of the prism rod 11, so that the mounting cover 13 can be stably clamped on the prism rod 11 through the elastic card groove 131; when the cover is opened, the mounting cover 13 is clamped on the prism rod 11. It is worth mentioning that, for the sake of ease of understanding, the surface on the reflective sheet 3 for reflecting the surveying and mapping light is defined as the reflecting surface 31, the surface on the reflecting prism 2 for reflecting the surveying and mapping light is defined as the mirror surface 21, and the orthogonal projection of the axis of the prism rod 11 on the reflecting surface 31 is defined as the centering line. When the cover is opened, the reflecting surface 31 and the mirror surface 21 are oriented in the same direction, and the orthogonal projection of the center of the mirror surface 21 on the reflecting surface 31 and the center of the reflecting surface 31 are both located on the centering line, so that the reflecting prism 2 and the reflecting sheet 3 on the surveying and reflecting device can be centered through the prism rod 11. There is a fixed distance difference between the reflecting prism 2 and the reflecting sheet 3, so that the data can be substituted into the calculation later.

[0046] It is worth mentioning that in the embodiment of the present application, a soft buffer pad 4 is provided on the end face opposite to the mirror surface 21 of the reflective prism 2. When the cover is closed, the soft buffer pad 4 faces the reflective opening 121, and the reflective sheet 3 is pressed against the soft buffer pad 4 to further protect the reflective sheet 3.

[0047] Reference Figure 1 and Figure 3 In order to save space, the prism rod 11 is composed of an upper support rod 111 hinged on the installation box body 12 and a lower support rod 112 hinged on the upper support rod 111. The upper support rod 111 and the lower support rod 112 can rotate and fit on the outer wall of the installation box body 12.

[0048] The mounting box body 12 has a mounting surface for connecting the upper support rod 111. When the cover is closed, the prism rod 11 is attached to the outer wall of the mounting box body 12. In order to stably attach the prism rod 11 to the outer wall of the mounting box body 12, a clamping portion 113 is provided on the lower support rod 112, and a clamping groove 132 is provided on the mounting cover 13 corresponding to the clamping portion 113. When the cover is closed, the clamping portion 113 is inserted into the clamping groove 132. In the embodiment of the present application, the clamping portion 113 is an "L"-shaped metal rod, and a positioning magnet for adsorbing the metal rod is provided in the clamping groove 132.

[0049] Reference Figure 4 and Figure 5The surveying and mapping reflection device also includes a limiting member 5 for limiting the rotation of the mounting cover 13 and the prism rod 11. The limiting member 5 includes a first pin 51 for limiting relative rotation between the upper support rod 111 and the lower support rod 112, a second pin 52 for limiting relative rotation between the upper support rod 111 and the mounting box body 12, and a third pin 53 for limiting relative rotation between the mounting cover 13 and the mounting box body 12. The first pin 51, the second pin 52, and the third pin 53 are all slidably mounted in the mounting box body 12.

[0050] A first channel 1111 is provided on the upper support rod 111, and a first blind hole 1121 for aligning with the first channel 1111 is provided on the lower support rod 112. When the cover is opened, one end of the first pin shaft 51 is located in the first blind hole 1121, and the other end of the first pin shaft 51 is located in the first channel 1111 to lock the relative rotation between the upper support rod 111 and the lower support rod 112.

[0051] A second blind hole 1112 is also provided in the upper support rod 111. When the cover is opened, one end of the second pin 52 is located in the second blind hole 1112, and the other end of the second pin 52 is located in the mounting box body 12 to lock the relative rotation between the upper support rod 111 and the mounting box body 12.

[0052] A third blind hole 133 is provided on the mounting cover 13. When the cover is opened, one end of the third pin 53 is located in the third blind hole 133, and the other end of the third pin 53 is located in the mounting box body 12 to lock the relative rotation between the mounting cover 13 and the mounting box body 12.

[0053] Reference Figure 6 To prevent the first, second, and third pins 51, 52, and 53 from falling out of the mounting box 12 when the lid is closed, the surveying and mapping reflectance device further includes an opening and closing member 6 for restricting the movement of the limiting member 5 within the box. The opening and closing member 6 is provided with a cable 61 for pulling the opening and closing member 6 open and a return spring 62 for driving the opening and closing member 6 to slide closed. One end of the opening and closing member 6 is secured to the inner wall of the mounting cover 13 via the cable 61, while the other, opposite end of the opening and closing member 6 is secured to the mounting box 12 via the return spring 62.

[0054] In this embodiment, the cable 61 is a flexible steel cable, and the opening and closing member 6 is a slide plate with a through hole. A slot is provided in the mounting box 12 for the opening and closing member 6, and the opening and closing member 6 is slidably mounted within the slot. The surface of the mounting box 12 that is hingedly connected to the upper support rod 111 is provided with a first through hole for alignment with the first channel 1111, a second through hole for alignment with the second blind hole 1112, and a third through hole for alignment with the third blind hole 133.

[0055] When the lid is in the closed state, the through holes on the opening and closing member 6 are staggered with the first through hole, the second through hole, and the third through hole. In the process from the closed state to the open state, the installation cover 13 rotates and drives the opening and closing member 6 to slide through the pull rope 61. When the lid is in the open state, several through holes on the opening and closing member 6 are aligned with the first through hole, the second through hole and the third through hole, so that the first pin shaft 51 slidably installed in the installation box body 12 slides into the first channel 1111, the second pin shaft 52 slides into the second blind hole 1112, and the third pin shaft 53 slides into the third blind hole 133.

[0056] In the process of changing from the open state to the closed state, in actual working conditions, the surveying and reflecting device is inverted to return the pin shaft to its original position, and then the installation cover plate 13 rotates, and the return spring 62 drives the opening and closing member 6 to slide in the corresponding slide groove. The several through holes on the opening and closing member 6 are misaligned with the first through hole, the second through hole, and the third through hole on the installation box body 12, thereby preventing the pin shaft from sliding out. It is worth mentioning that in the embodiment of the present application, the opening and closing member 6 includes a middle opening and closing slide plate for opening and closing the first through hole and the second through hole, and also includes a side opening and closing slide plate for opening and closing the second through hole; the number of the side opening and closing slide plates is two, and each side opening and closing slide plate corresponds to a third through hole and a third blind hole 133. The two side opening and closing slide plates are respectively arranged on both sides of the hinge between the upper support rod 111 and the installation box body 12, so that the rotation limit of the installation cover plate 13 is more stable.

[0057] The implementation principle of one embodiment of the present application is as follows: under normal circumstances, the surveying and mapping reflector is in a closed state; when surveying and mapping is in progress, the surveying and mapping reflector is in an open state. When switching from the closed state to the open state, the lower support rod 112 is first rotated to release the positioning of the clamping portion 113, and the prism rod 11 is vertically unfolded. The mounting cover 13 is then unfolded so that it is clamped onto the prism rod 11. After surveying and mapping is completed, when switching from the open state to the closed state, the surveying and mapping reflector is first inverted to return the stopper 5 to its original position. The mounting cover 13 is then rotated to contact the mounting box 12. Finally, the prism rod 11 is rotated to fit against the side wall of the mounting box 12, and the clamping portion 113 is installed in the clamping groove 132.
