Description

Technical Field

[0001] The utility model belongs to the technical field of underforest surveying and mapping, and particularly relates to an underforest surveying and mapping support. Background Technique

[0002] Underforest surveying and mapping refers to the surveying and mapping work carried out in forest-covered areas, aiming to obtain relevant information such as the terrain and ground features under the forest. Large-scale and high-precision underforest terrain surveying and mapping is of great significance for evaluating forest growth conditions, carbon storage, and forest resource monitoring. When conducting underforest surveying and mapping, surveyors need to use professional surveying instruments to collect data. At the same time, in order to make the data obtained by the surveying instruments more accurate, a support is needed to support the surveying instruments. However, when conducting underforest surveying and mapping, there is a problem of variable terrain undulation. When surveyors move their positions, the terrain will have a certain impact on the movement of surveyors, making it inconvenient for surveyors to transfer in the undulating and variable terrain while carrying the surveying instrument and the support. Content of the Utility Model

[0003] The utility model provides an underforest surveying and mapping support, which has the characteristics that a measuring instrument can be supported by three support rods. When the three support rods rotate to be parallel to each other, and the three connecting rods I and the three connecting rods II are in close contact with each other, the force on the three support rods will be more concentrated. Thus, the three retracted support rods can be used as crutches, which is beneficial to improving the stability and convenience of surveyors' movement in the forest.

[0004] The utility model provides the following technical solution: including a surveying instrument connecting seat, which is characterized in that: three support rods are rotatably connected to the bottom of the surveying instrument connecting seat. The support rod includes a connecting rod I, a connecting rod II, an internal thread tube, and a positioning rod. The connecting rod I is one-third of a cylinder, and the connecting rod II has the same size as the connecting rod I. A fixing block is arranged on one side of the connecting rod I, and a fixing seat is arranged on one side of the connecting rod II. A threaded rod is rotatably connected to the top of the fixing seat, and the threaded rod is in threaded connection with the fixing block. The connecting rod I and the connecting rod II are connected by a plurality of connecting rods. The internal thread tube is rotatably connected to the bottom of the connecting rod II. The outer side of the positioning rod is provided with an external thread. An empty groove and a through groove are formed inside the connecting rod II. A through hole is formed at the top of the positioning rod. A movable plate is movably connected to the inside of the empty groove. The positioning rod is movably connected to the inside of the internal thread tube and the through groove. A connecting buckle is arranged on one side of one of the connecting rod II, a binding band is arranged on one side of the connecting buckle, and a sleeve ring is arranged at one end of the binding band far away from the connecting buckle.

[0005] Among them, a connecting block is arranged on one side of the top of the connecting rod I, and the connecting block is rotatably connected to the bottom of the surveying instrument connecting seat.

[0006] Among them, a threaded groove is provided inside the fixed block, and the threaded rod is threadedly connected to the threaded groove.

[0007] Among them, a plurality of connection grooves are provided at the top of the second connecting rod, and a plurality of connection rods are fixedly connected to the bottom of the connection rod, and the connection rod is movably connected to the connection groove.

[0008] Among them, a plurality of guide rods are provided inside the empty groove, a plurality of through holes are provided on the movable plate, and the guide rods are located inside the through holes.

[0009] The beneficial effects of the present utility model are as follows: The upper surveying instrument connecting seat and the measuring instrument can be supported by three support rods, so that they remain stable during the measurement process. When the three support rods rotate to be parallel to each other, the three support rods will be in a retracted state, and the three connecting rods one and the three connecting rods two are in close contact with each other, so that the three support rods form a complete cylinder, and the force on the three support rods will be more concentrated. Therefore, the three retracted support rods can be used as crutches. When the surveying personnel walk in the forest, they can be supported by them, which is beneficial to improving the stability and convenience of the surveying personnel moving in the forest.
