[0002] Water is the basic element for human survival, and electricity is the main energy for social development. Water conservancy and hydropower engineering is an engineering that controls and utilizes water energy resources based on the study of the natural characteristics of water. The support frame is a common device in water conservancy and hydropower engineering, used to support survey devices in water conservancy and hydropower engineering.

[0003] The existing public patent, with the public number CN213236722U, discloses a device support frame for water conservancy and hydropower engineering survey, which includes a placement table. Three fixed blocks are uniformly distributed and fixedly connected to the bottom of the placement table. Elastic rods are arranged at positions corresponding to the three fixed blocks on the bottom of the placement table. The top of each elastic rod is fixedly connected to a connecting block that is nested with the fixed block. A placement groove is arranged at the center of the top of the placement table. A fixed seat is nested in the placement groove. A surveying device is rotatably connected to the top of the fixed seat. Two inner grooves are arranged on both sides of the placement table. A moving block is arranged in each inner groove. A return spring is connected between the inner wall of each inner groove and the outer surface of each moving block. A limiting block is fixedly connected to the outer surface of each moving block away from the return spring. A driving rod is fixedly connected to the top of each moving block. An active groove is arranged on the top of the placement table and communicates with the two inner grooves. The two driving rods are correspondingly nested and slidably connected with the two active grooves.

[0004] When the fixed seat is clamped into the placement groove, the hands need to be used to drive the driving rod to prevent the limiting block from blocking the placement groove.
