Description

Technical Field

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

[0002] A GPS locator is a device that determines its own location, speed, and time by receiving signals from Global Positioning System (GPS) satellites.

[0003] Reference to the utility model patent with authorization announcement number CN220601121 U discloses a GPS positioning device for engineering surveying, including a GPS positioning device body, an installation mechanism detachably connected to the GPS positioning device body and used to support the GPS positioning device body, a support adjustment mechanism connected to the installation mechanism through a connecting mechanism, and a level located on the installation mechanism for indicating whether the GPS positioning device body is in a horizontal position. The support adjustment mechanism of this utility model is connected to the installation mechanism through the connecting mechanism, so that the height of the GPS positioning device body can be adjusted in the vertical direction. At the same time, the installation mechanism can make the GPS positioning device body rotate in the horizontal direction to adjust the orientation of the GPS positioning device body in the horizontal direction, so as to measure different angles in the horizontal direction. The support adjustment mechanism facilitates the adjustment of the level and height of the installation mechanism, which is convenient to operate and does not require reinstallation of the support adjustment mechanism, thus improving work efficiency.

[0004] The GPS positioning device in the aforementioned patent is fixed using a traditional tripod, and its leveling requires manual adjustment, which is quite troublesome and depends on the operator's skill level. To solve the above problems, we propose a GPS positioning device for engineering surveying. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a GPS positioning device for engineering surveying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A GPS positioning device for engineering surveying includes a structural support plate with a fixed adjustment mechanism on its upper side. The fixed adjustment mechanism includes a mounting disc with three ball sleeves screwed to its bottom. Three electric telescopic rods are mounted on the upper side of the structural support plate, with ball seats fixedly mounted on the upper side of the output end of each electric telescopic rod. The ball seats are embedded inside the ball sleeves. A three-dimensional tilt sensor is screwed to the center of the bottom of the mounting disc. A fixing annular groove is fixedly mounted on the upper side of the mounting disc, with limit bolts screwed onto the sidewall of the fixing annular groove, extending through to the inside of the groove. Three vertical holes are formed on the upper side of the structural support plate, with locking holes inside each hole. A chuck is fixedly mounted on the bottom of each electric telescopic rod, locking into the locking holes.

[0008] Furthermore, the three ball sleeves and the three electric telescopic rods are all distributed at equal angles around the circumference, and the installation positions of the ball sleeves correspond one-to-one with the installation positions of the electric telescopic rods.

[0009] Furthermore, an abutment piece is fixedly installed on the inner end of the limiting bolt, and a GPS locator is placed inside the fixing ring groove, with the abutment piece abutting against the outer wall of the GPS locator.

[0010] Furthermore, the contact piece is a rubber pad.

[0011] Furthermore, a protective cover is fixedly installed at the bottom of the structural support plate, a charging interface is fixedly installed at the bottom of the protective cover, and heat dissipation holes are provided on the side wall of the protective cover.

[0012] Furthermore, a battery and a control processor are provided inside the protective cover. The battery is fixedly installed at the bottom of the structural support plate, and a heat insulation board is fixedly attached to the bottom of the battery. The control processor is fixedly installed at the bottom of the heat insulation board.

[0013] Furthermore, three telescopic rods are rotatably mounted on the bottom of the structural support plate, and limit screws are screwed onto the side walls of the telescopic rods. A ground-inserting tip is fixedly connected to the lower end of the telescopic rod.

[0014] Furthermore, the inner diameter of the vertical hole is larger than the outer diameter of the electric telescopic rod, and the inner diameter of the chuck hole is larger than the outer diameter of the chuck.

[0015] Compared with related technologies, the GPS positioning device for engineering surveying proposed in this utility model has the following beneficial effects:

[0016] This invention discloses a GPS positioning device for engineering surveying. Through a fixed adjustment mechanism, a heat dissipation tilt sensor detects the horizontal state of the mounting disc, transmitting the data to a control processor for processing. Three equidistantly distributed electric telescopic rods adjust the horizontal state of the mounting disc. The controller, based on tilt sensor feedback, adjusts the extension and retraction of each electric telescopic rod, thereby automatically leveling the mounting disc and ensuring the GPS positioning device mounted on it remains horizontal. This facilitates accurate positioning. Compared to the traditional manual adjustment using a tripod, this invention automates the horizontal adjustment process, eliminating reliance on operator skill and improving the efficiency of GPS positioning device horizontal setup, thus enhancing surveying efficiency and practicality.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-5 A GPS positioning device for engineering surveying includes a structural support plate 1, with a fixed adjustment mechanism 5 on the upper side of the structural support plate 1. The fixed adjustment mechanism 5 includes a mounting disc 51, with three ball sleeves 52 screwed onto the bottom of the mounting disc 51. Three electric telescopic rods 53 are provided on the upper side of the structural support plate 1. Ball seats 54 are fixedly installed on the upper side of the output end of the electric telescopic rods 53, and the ball seats 54 are embedded in the inner side of the ball sleeves 52. A three-dimensional tilt sensor 55 is screwed onto the center position of the bottom of the mounting disc 51. A fixed annular groove 56 is fixedly installed on the upper side of the mounting disc 51. Limit bolts 57 are screwed onto the side wall of the fixed annular groove 56 and screwed through to the inner side of the fixed annular groove 56. Three vertical holes 59 are opened on the upper side of the structural support plate 1, and a locking hole 510 is opened inside the vertical holes 59. A chuck 511 is fixedly installed on the bottom of the electric telescopic rods 53 and the chuck 511 is locked into the inner side of the locking hole 510.

[0025] By tightening the limiting bolt 57, the inner end of the limiting bolt 57 abuts against the GPS locator 6, thereby fixing the GPS locator 6 inside the fixing ring groove 56. This arrangement facilitates the installation and removal of the GPS locator 6.

[0026] In this method, a contact piece 58 is fixedly installed on the inner end of the limiting bolt 57, and a GPS locator 6 is placed inside the fixing ring groove 56. The contact piece 58 abuts against the outer wall of the GPS locator 6, and the contact piece 58 is a rubber gasket.

[0027] By setting it in the above manner, the contact piece 58 is set as a rubber pad, which avoids the inner end of the limit bolt 57 from causing contact damage to the outer wall of the GPS locator 6.

[0028] In this method, three telescopic rods 2 are rotatably installed at the bottom of the structural support plate 1, and limit screws 3 are screwed onto the side wall of the telescopic rods 2. The lower end of the telescopic rods 2 is fixedly connected to a grounding tip 4.

[0029] By setting it in the above manner, the limiting screw 3 can limit the automatic extension and retraction of the telescopic rod 2, and the ground insertion tip 4 can allow the lower end of the telescopic rod 2 to be inserted into the ground surface, thereby improving the support stability of the entire support system.

[0030] In this method, the three ball sleeves 52 and the three electric telescopic poles 53 are all distributed in a circular equiangular pattern, and the installation positions of the ball sleeves 52 and the electric telescopic poles 53 correspond one-to-one.

[0031] By adjusting the extension and retraction of the three electric telescopic rods 53 as described above, the tilt angle of the mounting disc 51 can be adjusted.

[0032] In this method, a protective cover 7 is fixedly installed at the bottom of the structural support plate 1, a charging interface 72 is fixedly installed at the bottom of the protective cover 7, and heat dissipation holes 71 are provided on the side wall of the protective cover 7.

[0033] With the above-described configuration, the heat dissipation hole 71 facilitates heat dissipation for the working components inside the protective cover 7.

[0034] In this method, a battery 8 and a control processor 10 are provided inside the protective cover 7. The battery 8 is fixedly installed at the bottom of the structural support plate 1, and a heat insulation plate 9 is fixedly attached to the bottom of the battery 8. The control processor 10 is fixedly installed at the bottom of the heat insulation plate 9.

[0035] By setting up the heat insulation plate 9 as described above, the heat generated by the battery 8 during operation is prevented from interfering with the control processor 10.

[0036] In this method, the inner diameter of the vertical hole 59 is larger than the outer diameter of the electric telescopic rod 53, and the inner diameter of the locking hole 510 is larger than the outer diameter of the chuck 511.

[0037] With the above-described configuration, the adjustment of the three electric telescopic rods 53 will cause the upper mounting disc 51 to tilt. The lower end of the electric telescopic rod 53 is slidably engaged with the locking hole 510 via the chuck 511, and will adaptively slide during adjustment to counteract the motion interference caused by the tilt of the upper mounting disc 51. The chuck 511 and the locking hole 510 have a locking and sliding damping effect, resulting in good stability and maintaining stability in daily use.

[0038] The working principle of the GPS positioning device for engineering surveying provided by this utility model is as follows:

[0039] In use, the surveyor first moves the GPS positioning device to the measurement point. The structural support plate 1 is placed on the ground, and the three telescopic rods 2 at the bottom of the support plate 1 are rotated to adjust their length to suit different terrains. The telescopic rods 2 are then fixed in place by the limiting screws 3. Next, the ground-inserting tips 4 at the lower ends of the telescopic rods 2 are inserted into the ground. The tight engagement between the tips and the ground provides a stable support foundation for the entire positioning device, preventing shaking or displacement during the measurement process.

[0040] Next, the GPS locator 6 is installed. The GPS locator 6 is placed in the fixing ring groove 56 on the upper side of the mounting disc 51. By rotating the limiting bolt 57, the rubber contact piece 58 at the inner end of the limiting bolt 57 is tightly abutted against the outer wall of the GPS locator 6, thus firmly fixing the GPS locator 6 inside the fixing ring groove 56, completing the initial installation. After the equipment is placed and fixed, the automatic leveling system starts. The three-dimensional tilt sensor 55 at the center of the bottom of the mounting disc 51 then begins to work, collecting real-time tilt angle data of the mounting disc 51 in the X, Y, and Z axes. The three-dimensional tilt sensor 55 transmits the collected tilt angle information to the control processor 10 inside the protective cover 7 in the form of electrical signals. After receiving the data transmitted by the three-dimensional tilt sensor 55, the control processor 10 immediately analyzes and processes the data. The control processor 10 has a built-in preset leveling algorithm. This algorithm compares the received tilt angle data with the standard data of the horizontal state, calculates the deviation of the mounting disk 51 from the horizontal state in each axis, and generates extension control commands for the three electric telescopic rods 53 according to predetermined logic rules based on the calculated deviation. These commands specify the extension length required for each electric telescopic rod 53, and the electric telescopic rod 53 performs the extension action after receiving the command. Since the three ball sleeves 52 and the three electric telescopic rods 53 are distributed at equal angles around the circumference, and the ball seat 54 is embedded inside the ball sleeve 52, this structural design allows the electric telescopic rods 53 to drive the mounting disk 51 to tilt and adjust in different directions during extension and retraction. During the leveling process, the electric telescopic rods 53 adjust their extension lengths according to the commands of the control processor 10. The three electric telescopic rods 53 work together to continuously adjust the posture of the mounting disc 51 until it is adjusted to a horizontal state. When the mounting disc 51 reaches a horizontal state, the GPS locator 6 fixed on it is also in a horizontal position. At this time, the GPS locator 6 can start to receive signals from the Global Positioning System (GPS) satellites to determine the position, speed and time information, and prepare for subsequent engineering measurement work.
