Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and in particular to a portable level for water conservancy projects. Background Art

[0002] Ecological river management projects refer to activities that promote the recovery of river water ecosystems through artificial restoration measures within the river land control line, on the basis of meeting the basic functions of the river such as flood control, drainage and water diversion, and build a healthy, complete and stable river water ecosystem. Levels are often used in ecological river management projects. Levels are instruments that establish a horizontal line of sight to measure the height difference between two points on the ground. The principle is to measure the height difference between ground points based on the principle of leveling.

[0003] Chinese patent CN214171791U proposes a portable level, which reduces the volume of the level by telescoping the legs. However, in this structure, the three legs with telescopic function need to be adjusted independently to complete the telescoping, which is inconvenient to operate. After being stored, the length is only reduced, and the overall carrying is still inconvenient and the structure is relatively scattered. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposed.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A portable level for water conservancy projects comprises a hollow tube, a mounting seat is provided on the top of the hollow tube, and a level body is provided on the mounting seat; a handle is provided on the side of the hollow tube for the user to hold; an adjustment rod is slidably arranged in the hollow tube, and the adjustment rod cooperates with a butterfly bolt threadedly arranged on the hollow tube so that the position of the adjustment rod is fixed after extension and retraction; three installation slots are provided on the adjustment rod, and a telescopic leg for contacting the ground is rotatably connected in each installation slot so that the telescopic leg can be stored in the installation slot or extended to the outside of the installation slot.

[0007] Furthermore, the telescopic leg includes an internal threaded tube and an external threaded rod, one end of the internal threaded tube is rotatably arranged in the installation groove, and the internal thread of the internal threaded tube is connected to the external threaded rod so that the device can be fixed and the angle can be adjusted by adjusting the external threaded rod.

[0008] Furthermore, a conical base is provided at the bottom of the externally threaded rod to improve the stability of the device.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model has a foldable storage function, which realizes the purpose of stretching when in use and folding when not in use. After storage, the volume of the device is greatly reduced, which is convenient for users to carry. When stored, the adjusting rod and the telescopic legs are both inside the hollow tube. At this time, the user can transfer and carry the device by operating the handle. When unfolded, according to the specific use requirements of the water conservancy project scene, the butterfly bolt is loosened so that it does not contact the adjusting rod. At this time, the adjusting rod is pulled to an appropriate length, and then the butterfly bolt is tightened to complete the adjustment of the use height of the device. Then, the three telescopic legs are pulled out away from the installation groove to form a triangular structure and fixed to the ground. Finally, the external threaded rod of the telescopic leg can be fine-tuned according to the horizontal position of the level, which can adapt to the use of different grounds and improve the practicality of the level.
