Description

Technical Field

[0001] This utility model relates to the field of surveying instrument technology, and in particular to a portable surveying device for building engineering. Background Technology

[0002] Surveying instruments are a class of specialized equipment used to measure the Earth's surface topography, landforms, geographic information, and to conduct engineering surveys. They play an important role in fields such as geographic information science, engineering construction, urban planning, land resource surveys, and environmental monitoring. Simply put, surveying instruments are instruments and devices designed and manufactured for data acquisition, processing, and output in surveying operations. They are various instruments used for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry during the planning, design, construction, and operation management phases of engineering construction.

[0003] Surveying instruments are easily affected by environmental changes during the measurement process, leading to unstable measurement accuracy and thus affecting engineering construction measurements. Environmental changes include the influence of lighting. During the measurement process, sunlight shining on the observation lens causes lighting effects, which are not conducive to measurement. Secondly, they are easily affected by electromagnetic interference in complex environments. For example, when measuring near large power facilities, high-voltage transmission lines, radio transmission towers, motors and other strong electromagnetic fields, the electronic components inside the measuring equipment may be affected by electromagnetic induction when the measuring equipment is close to these power facilities, resulting in inaccurate measurement data. To address this, a portable surveying device for building engineering is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a portable surveying device for building engineering, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A portable surveying device for construction engineering includes a portable placement tray, a support leg at the bottom of the portable placement tray, a portable moving component on the support leg, a connecting seat at the top of the portable placement tray, a surveying instrument body rotatably mounted inside the connecting seat, a top shielding plate fixedly mounted on the top of the surveying instrument body, side shielding plates on both sides of the top shielding plate, and an adjustment plate mounted on the top shielding plate via an adjustment component, which is used to block light when pulled out.

[0006] Preferably, the adjustment assembly includes an adjustment groove formed on the side of the top shielding plate, and the adjustment plate is movably installed in the adjustment groove.

[0011] Preferably, the surveying instrument body has an observation port and a measurement port on both sides, and a top handle is provided on the top of the connecting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The portable surveying device for building engineering is equipped with a portable moving component. The operator can quickly pull the support leg away by pulling the storage handle with one hand and pulling the roller. It is easy to carry during movement and reduces the intensity compared to manual handling. The top shielding plate and side shielding plate can effectively block and absorb electromagnetic waves during use. The surveying instrument body will not be affected by electromagnetic waves during use, which can ensure the accuracy of measurement. The adjustable plate can move on the top shielding plate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to Figure 1-6 A portable surveying device for construction engineering includes a portable placement tray 1, with a support leg 2 at the bottom of the portable placement tray 1. A portable moving component is provided on the support leg 2, and the portable moving component includes a storage pull handle 3 fixedly installed on the side of the portable placement tray 1, a pull roller 4 installed on the side of one support leg 2, and a pull roller 4 provided on one support leg 2. During movement, the three support legs 2 are in a stored state. The worker can quickly pull the support leg 2 away by pulling the storage pull handle 3 with one hand and pulling the roller 4. It is easy to carry during movement and can reduce the intensity of manual handling.

[0017] Specifically, the portable placement tray 1 has a connecting base 5 on its top, and the surveying instrument body 7 is rotatably mounted inside the connecting base 5. A top shielding plate 10 is fixedly installed on the top of the surveying instrument body 7, and side shielding plates 11 are provided on both sides of the top shielding plate 10. An adjustment plate 13 is installed on the top shielding plate 10 through an adjustment assembly. The adjustment plate 13 is used to block light when it is pulled out. Observation ports 8 and measurement ports 9 are provided on both sides of the surveying instrument body 7, respectively. A top handle 6 is provided on the top of the connecting base 5. During use, the top shielding plate 10 and the side shielding plates 11 are provided on the outside of the surveying instrument body 7. The top shielding plate 10 and the side shielding plates 11 are made of aluminum alloy, which has good conductivity and magnetic permeability and can effectively block and absorb electromagnetic waves. When electromagnetic waves irradiate the shielding cover, the metal material will reflect most of the electromagnetic waves and absorb some of the electromagnetic waves, thereby preventing electromagnetic waves from entering the interior of the shielding cover. During use, the surveying instrument body 7 will not be affected by electromagnetic waves, and the measurement accuracy can be guaranteed.

[0018] Specifically, the adjustment assembly includes an adjustment groove 12 on the side of the top shielding plate 10, an adjustment plate 13 movably installed in the adjustment groove 12, a fixing screw hole 17 on the top of the top shielding plate 10, a fixing screw groove 18 on the top of the adjustment plate 13, a fixing bolt 19 threaded onto the fixing screw hole 17, and the bottom thread of the fixing bolt 19 threaded into the fixing screw groove 18. During the measurement process, when encountering strong light that may shine on the measurement port 9, the adjustment plate 13 is pulled out. After the adjustment plate 13 is pulled out, it can extend the area blocked above, so that the light will not shine into the measurement port 9, thus forming a good measurement shielding effect and avoiding the influence of light on the measurement. The fixing bolt 19 can fix the position of the adjusted adjustment plate 13.

[0019] Specifically, a side sliding groove 14 is provided on the inner wall of the adjustment groove 12, and a side sliding column 16 is fixedly installed on the side of the adjustment plate 13. The side sliding column 16 is slidably installed in the side sliding groove 14. A protective drop groove 15 is provided at the bottom of the side sliding groove 14, and an installation groove is provided at the bottom of the adjustment plate 13. A first magnetic block 20 is installed in the installation groove, and a second magnetic block 21 is fixedly installed on the side of the surveying instrument body 7. The first magnetic block 20 and the second magnetic block 21 are compatible. When not in use, the adjustment plate 13 continues to move outward. When the side sliding column 16 on the side of the adjustment plate 13 moves into the protective drop groove 15, the adjustment plate 13 can rotate to a vertical state. Under the interaction of the first magnetic block 20 and the second magnetic block 21, the measuring port 9 can be protected, and the protection effect is good.

[0020] In use: When using the surveying instrument body 7 to conduct site surveying at a construction site, the worker can quickly pull away the support leg 2 by pulling the storage handle 3 with one hand and pulling the roller 4. This makes it easy to carry during movement and reduces the intensity compared to manual handling. During use, the surveying instrument body 7 is equipped with a top shielding plate 10 and a side shielding plate 11 on its outer side. When electromagnetic waves shine on the shielding cover, the metal material will reflect most of the electromagnetic waves and absorb some of them, thus preventing electromagnetic waves from entering the shielding cover and ensuring measurement accuracy. During measurement, the adjustment plate 13 can be pulled outward to extend the area blocked above, preventing light from shining into the measurement port 9, thus forming a good measurement shielding effect and avoiding light affecting the measurement. When not in use, the adjustment plate 13 can be rotated to a vertical position, and the interaction of the first magnetic block 20 and the second magnetic block 21 can protect the measurement port 9, providing good protection and ease of use.
