Description

Technical Field

[0001] The present invention relates to the technical field of surveying instruments, and specifically to a surveying instrument for information engineering surveying and mapping with an automatic calibration component. Background Technique

[0002] A surveying instrument combines optics, mechanics, and electronics to capture a workpiece, process it by computer, and magnify it 18 to 230 times, display it on a screen, and can directly take pictures for archiving or perform surface observation, measurement, and drawing.

[0003] In the prior art, the patent number is CN118243061B, and the name is a portable land surveying instrument with an automatic calibration function. It includes a support plate, the support plate is ball-jointed with an adjustment frame, a measuring mechanism is arranged on the upper part of the adjustment frame, the adjustment frame is rotatably connected with a second elastic telescopic rod, the telescopic end of the second elastic telescopic rod is fixedly connected with a first push rod, a sliding frame with a torsion spring arranged between the telescopic end of the first push rod is slidably connected to the adjustment frame, a rotating frame is slidably connected to the sliding frame, an adjustment elastic telescopic rod is rotatably connected to the rotating frame, and a detection rod is hinged to the adjustment elastic telescopic rod. When fixing the device, by rotating the adjustment frame around the support plate, the sliding frame is in a vertical state, and when measuring the slope angle of a hillside, the detection rod is driven to rotate by the rotating frame, so that the detection rod is in the same direction as the slope of the mountain body, improving the accuracy of the data.

[0004] However, during the process of the staff placing the surveying instrument, it is difficult to ensure that the direction of the measuring rod on the slope ruler is the same as the direction of the slope of the area to be measured on the mountain body, resulting in an angle between the measuring rod and the mountain slope. At the same time, during the process of the staff fixing the surveying instrument, due to the slope of the mountain body itself, it is difficult for the staff to always ensure that the fixing rod of the slope ruler is in a vertical state. Summary of the Invention

[0005] The purpose of the present invention is to provide a surveying instrument for information engineering surveying and mapping with an automatic calibration component to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A surveying instrument for information engineering surveying and mapping with an automatic calibration component, including:

[0007] A measuring head, with a support rod and a gravity ball arranged at the bottom of the measuring head;

[0008] A circular ring, with a spherical ball arranged inside the circular ring, a fixed rod arranged outside the circular ring, an outer ring arranged at the end of the fixed rod, a U-shaped ring arranged outside the outer ring, an air charging pipe arranged inside the U-shaped ring, a connecting pipe arranged on the surface of the air charging pipe; and a screwing ring, arranged inside the circular ring.

[0009] Preferably, a connecting rod is fixed to the bottom of the measuring head. The bottom of the connecting rod is connected to a spherical ball. The spherical ball is located inside the ring and can roll inside the ring. A vertical rod is fixed to the bottom of the spherical ball, and a gravity ball is fixed to the bottom of the vertical rod.

[0010] Preferably, a screwed ring is screwed onto the surface of the ring. A screwing ring is fixed to the top of the screwed ring. A swing rod is hinged to the surface of the screwing ring through a rotating shaft. A holding block is fixed to the end of the swing rod. A rubber strip is arranged at the bottom of the holding block. An elastic plate is connected to the surface of the swing rod, and the other end of the elastic plate is connected to the surface of the screwing ring. The elastic plate has a thrust on the swing rod, so that the holding block holds against the surface of the outer ring.

[0011] Preferably, a rubber strip is arranged on the surface of the outer ring. A U-shaped ring is fixed to the surface of the outer ring. An inflatable tube is placed inside the U-shaped ring. A connecting tube on the surface of the inflatable tube is connected to an inflation device. The inflation device fills gas into the inside of the inflatable tube. A stress plate is arranged inside the U-shaped ring. A holding rod is fixed to the surface of the stress plate. The holding rod is inserted into the inside of the outer ring, and the other end of the holding rod is inserted into the inside of the ring. The holding rod can move inside the ring and the outer ring.

[0012] Preferably, a spring is connected to the surface of the stress plate, and the other end of the spring is connected to the surface of the outer ring. The spring has a thrust on the stress plate, so that the stress plate holds against the surface of the inflatable tube.

[0013] Preferably, a holding groove is formed on the surface of the holding rod, and a lifting groove is formed inside the ring. The screwed ring is screwed into the lifting groove, and the screwed ring can rotate and lift in the lifting groove.

[0014] Preferably, after the holding rod moves, it holds against the surface of the spherical ball to keep the spherical ball stable. After the screwed ring descends, it holds in the holding groove, and the holding of the screwed ring makes the end of the holding rod close to the surface of the spherical ball.

[0015] Preferably, after the inflatable tube is inflated, the surface of the inflatable tube holds against the surface of the stress plate, so that the stress plate moves towards the spherical ball, the spring is compressed, and the holding rod moves along with the stress plate.

[0016] Preferably, when the spherical ball swings inside the ring, the measuring head swings along with the spherical ball, and the measuring head swings around the center of the spherical ball.

[0017] Preferably, the bottom of the inflatable tube is fixed inside the U-shaped ring, and the surface of the inflatable tube deforms after being inflated inside.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The present invention proposes to stably support the measuring head through a support rod. By screwing the screwing ring, the screwed ring rises inside the circular ring, and the bottom of the screwed ring does not contact the holding rod. Under the action of the spring, the end of the holding rod moves away from the spherical ball. Under the gravitational action of the gravity ball at the bottom of the spherical ball, the measuring head is driven by the connecting rod to remain vertical. The inflation device inflates the inflatable pipe through the connecting pipe. After the inflatable pipe is inflated, it abuts against the surface of the force-receiving plate, causing the holding rod to approach the spherical ball. The holding rod abuts against the surface of the spherical ball to stabilize the spherical ball. By screwing the screwing ring, the screwed ring descends in the circular ring. After the screwed ring descends, it abuts against the holding groove on the surface of the holding rod, causing the holding rod to stably abut against the surface of the spherical ball. And under the push of the elastic plate, the holding block at the end of the swinging rod abuts against the surface of the outer ring. Rubber strips are provided on the surface of the outer ring and the bottom of the holding block to make the screwing ring stable. BRIEF DESCRIPTION OF THE DRAWINGS
