Description

Technical Field

[0001] This utility model relates to the field of geographic information surveying and mapping technology, specifically to an angle-adjustable geographic information surveying and mapping device. Background Technology

[0002] Geographic information is the digital representation of various states of the Earth's surface, providing a basis for research, reference, and construction. Therefore, the accuracy of geographic information data is of paramount importance. Current geographic data testing methods include: First, measurement via remote sensing satellites. Remote sensing satellites offer a wide measurement range and high speed, but their accuracy is not very high. Second, the most basic method is manual surveying. Manual surveying is slow and inefficient, but its accuracy is excellent. For vertical terrain and karst caves, it allows for in-depth surveying. Therefore, manual surveying is indispensable for some major projects. Manual surveying requires the use of surveying equipment such as levels and total stations.

[0003] In existing technologies, total stations used for geographic information surveying typically use a circular level on the base in conjunction with leveling screws to level the equipment during measurement. After leveling, the equipment's left and right angles are adjusted on the horizontal plane by rotating the base and the total station body, thus adjusting the total station's surveying angle. However, this technology lacks a limiting mechanism, allowing the total station body to easily rotate during actual surveying, leading to angle deviations and affecting surveying accuracy. Furthermore, the eyepieces and objectives on the total station body lack protection, making them prone to accumulating dirt and affecting observation. Utility Model Content

[0004] The purpose of this utility model is to provide an angle-adjustable geographic information mapping device to solve the problems of the lack of a limiting mechanism between the body and the base of the existing total station used for geographic information mapping. In the actual mapping process, the total station body is easy to rotate, which leads to the deviation of the mapping angle and affects the mapping accuracy. At the same time, the eyepiece and objective lens on the total station body lack protection and are easily covered with dirt, which affects the observation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An angle-adjustable geographic information mapping device includes a total station body, a base rotatably connected to the bottom of the total station body, and a limit mechanism provided between the total station body and the base.

[0007] The limiting mechanism includes a connecting sleeve and a limiting ring. A handle is fixedly connected to one side of the connecting sleeve. A guide rod is slidably connected to the bottom of the handle. A lever is fixedly connected to the outer end of the guide rod. A spring is sleeved on the outer side of the guide rod between the lever and the handle. A limiting block is fixedly connected to the inner end of the guide rod. A toothed groove is fixedly connected to the bottom of the limiting block. A toothed ring is fixedly connected to the outer top of the limiting ring. The toothed ring and the toothed groove are snap-fitted together. A spring is fixedly connected to the bottom of the handle and to the inner side of the limiting ring. A rubber block is fixedly connected to the outer side of the spring. The outer side of the rubber block is in close contact with the inner side of the limiting ring. A movable groove is formed at the bottom of the handle and at a position corresponding to the limiting block. A permanent magnet is embedded in the inner wall of the movable groove on the side away from the guide rod. An objective lens cover and an eyepiece cover are fixedly connected to the top of the handle by ropes.

[0008] Preferably, the connecting sleeve is fixedly connected to the bottom of the total station body, the handle is located on one side of the total station body, and the limiting ring is fixedly connected to the top of the base.

[0009] Preferably, the objective lens cover is fitted onto the objective lens of the total station body, and the eyepiece cover is fitted onto the eyepiece of the total station body.

[0010] Preferably, the limiting block is made of cast iron and is connected to the movable groove by a snap-fit ​​sliding connection.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by adding a limiting mechanism between the total station body and the base, and by using the spring and rubber block inside the limiting mechanism to be in close contact with the limiting ring, the steering resistance of the total station body rotating around the base can be increased to prevent the generation of rotational inertia and avoid self-rotation; in addition, a limiting block is also slidably connected inside the handle, which can be engaged with the top toothed ring of the limiting ring through the bottom toothed groove of the limiting block to lock the observation direction of the total station body, so as to prevent the measurement angle from deviating and increase the accuracy of its measurement.

[0013] 2. In this utility model, by using a rope to fix the eyepiece cover and objective lens cover at the top of the handle, the eyepiece and objective lens can be protected when the total station is not in use, so as to reduce the dirt sticking to the lens and ensure its observation effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-7 This utility model provides a technical solution:

[0024] An angle-adjustable geographic information mapping device includes a total station body 1 for geographic information measurement; a base 2 is rotatably connected to the bottom of the total station body 1 for leveling the total station body and connecting it to a tripod; a limit mechanism 3 is provided between the total station body 1 and the base 2 for limiting the rotation angle between the total station body and the base, so as to achieve self-locking adjustment of the total station in the horizontal angle to prevent rotational deviation and affect the mapping accuracy;

[0025] The limiting mechanism 3 includes a connecting sleeve 301 and a limiting ring 302. A handle 303 is fixedly connected to one side of the connecting sleeve 301. A guide rod 304 is slidably connected to the bottom of the handle 303. A lever 305 is fixedly connected to the outer end of the guide rod 304. A spring 306 is sleeved on the outer side of the guide rod 304, between the lever 305 and the handle 303. A limiting block 307 is fixedly connected to the inner end of the guide rod 305. A toothed groove 308 is fixedly connected to the bottom of the limiting block 307. A toothed ring 309 is fixedly connected to the top outer side of the limiting ring 302. The toothed ring 309 and the toothed groove 308 are snap-fit ​​connected and used to lock after angle positioning during total station surveying to prevent deviation and ensure measurement accuracy. A spring 310 is fixedly connected to the bottom of the handle 303, inside the limiting ring 307. It has a certain structural elasticity and can realize a flexible connection between the rubber block and the limiting ring. A rubber block 311 is fixedly connected to the outside of the handle 303. The outer side of the rubber block 311 is in close contact with the inner side of the limiting ring 307. The close contact between the rubber block and the limiting ring ensures friction, thereby increasing the damping of the rotation of the total station body and achieving the effect of stopping immediately when the handle is released. This facilitates rapid horizontal angle positioning during geographic information mapping. A movable groove 312 is provided at the bottom of the handle 303, corresponding to the position of the limiting block 307. A permanent magnet 313 is embedded in the inner wall of the movable groove 312 on the side away from the guide rod 305. This is used to magnetically fix the limiting block to prevent it from loosening and to ensure its structural stability. The top of the handle 303 is fixedly connected to the objective lens cover 315 and the eyepiece cover 316 by ropes 314. These are used to cover and protect the eyepiece and objective lens on the total station body, so as to protect the lens when it is not in use, prevent dirt from sticking, and ensure the observation effect.

[0026] In this embodiment, please refer to Figure 5 The connecting sleeve 301 is fixedly connected to the bottom of the total station body 1, the handle 303 is located on one side of the total station body 1, and the limiting ring 302 is fixedly connected to the top of the base 2.

[0027] In this embodiment, please refer to the figure. The objective lens cover 315 is fitted onto the objective lens 101 of the total station body 1, and the eyepiece cover 316 is fitted onto the eyepiece 102 of the total station body 1, which satisfies its structural design.

[0028] In this embodiment, please refer to Figure 4 The limiting block 307 is made of cast iron and is connected to the movable groove 312 by a snap-fit ​​sliding connection.

[0029] The working principle of this utility model is as follows: First, the total station body 1 is fixed to the geographic information mapping point by fixing it to the base 2 and tripod. Then, the total station body is leveled using the leveling screws on the base 2 and the circular level. Next, the objective lens cover 315 and eyepiece cover 316 are removed, exposing the objective lens 101 and eyepiece 102. Then, the handle 303 is held with one hand, causing the total station body 1 to rotate around the base 2 for angle adjustment. During rotation, the rubber block 311 at the bottom of the handle 303 is in close contact with the inner side of the limiting ring to increase the turning friction, counteracting rotational inertia and providing damping, thus preventing the total station body from easily rotating. While preventing deviation, it assists the total station in quickly locating the surveying direction. After the surveying direction is located, the push block 305 can be pushed inward, which in turn drives the limit block 307 to move inward along the movable groove 312, so that its bottom toothed groove 308 engages with the toothed ring 309 on the limit ring 302, thereby locking the total station body 1 in the surveying direction to prevent it from deviating and to ensure surveying accuracy. At the same time, the cast iron limit block 307 can be attracted to the permanent magnet 313 for locking and mechanical reinforcement to prevent loosening. Its structure has good stability. Conversely, pulling the push block 305 outward keeps the toothed groove 308 and toothed ring 309 in the open position under the elastic force of the spring 306, so that the rotation angle of the total station body 1 can be readjusted again.
