Description

Technical Field

[0001] This utility model belongs to the field of water conservancy surveying technology, and in particular relates to a measuring instrument for water conservancy surveying. Background Technology

[0002] Traditional surveying operations often face the challenge of instrument setup and fixation. When the field survey environment is complex, conventional surveying instruments need to be fixed with the help of a stable base or manual assistance. If the geology is soft or the terrain is rugged, not only does the difficulty of fixing increase dramatically, but the unstable foundation may also lead to deviations in the measurement data. Especially in emergency survey scenarios, if there are sudden disasters such as floods or mudslides, there is often a lack of flat ground or fixed facilities on site. Surveyors have to operate the instruments by hand. At this time, problems such as instrument shaking and angle deviation can easily cause data errors. Moreover, it is difficult to maintain stability for a long time with manual support, which seriously affects the efficiency and accuracy of the survey. In addition, traditional fixing methods require carrying a lot of auxiliary equipment, which increases the load of field operations. In remote areas, transportation is inconvenient, which restricts the flexibility and timeliness of water conservancy surveys.

[0003] However, when using an existing water conservancy surveying instrument, due to the variability of the surveying scenarios and the increase in uncertain factors such as water flow, external forces can affect the measurement points of the instrument, causing instrument deviation and affecting the accuracy of the measurement data. Utility Model Content

[0004] The purpose of this utility model is to provide a measuring instrument for water conservancy surveying. By setting a fixing part, it solves the problem that when using an existing water conservancy surveying measuring instrument, due to the changing scenarios of water conservancy surveying, the increase of uncertain factors such as water flow, and the influence of external forces on the measuring point position of the measuring instrument, the instrument deviates and the accuracy of the measurement data is affected.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a measuring instrument for water conservancy surveying, including a chute plate and a plurality of supporting legs disposed below the chute plate. A fixing plate is disposed below the chute plate, and a measuring instrument is disposed on the top of the chute plate. It also includes: a fixing part disposed on the chute plate; and a supporting part disposed on the fixing plate; wherein the fixing part penetrates through the chute plate.

[0007] Furthermore, the fixing part includes a clamping assembly disposed on the slide plate; and a limiting assembly mounted on the clamping assembly; wherein the clamping assembly and the limiting assembly are fixedly connected.

[0008] Furthermore, the clamping assembly includes a fixed frame fixedly connected to the bottom of the slide plate, a rotating rod is provided on the fixed frame, a rotating plate is rotatably connected to the bottom inner wall of the fixed frame, a handle is fixedly connected to the bottom of the rotating rod, and a plurality of movable parts are provided on the rotating plate; wherein, the rotating rod passes through the fixed frame, the fixed frame is rotatably connected to the outer wall of the rotating rod, and the rotating plate is fixedly connected to the outer wall of the rotating rod, and the movable parts include a plurality of clamping blocks provided on the top of the slide plate, and a hinge plate is hinged to the bottom of each of the clamping blocks; wherein, the bottom of each of the clamping blocks passes through the slide plate, the outer wall of each of the clamping blocks is slidably connected to the slide plate, and the side of each of the hinge plates near the fixed frame is hinged to the rotating plate, and the clamping assembly drives the rotating rod and the rotating plate to rotate by rotating the handle, thereby driving the hinge plates to push the clamping blocks to move along the slide.

[0009] Furthermore, the limiting component includes a ratchet gear mounted on the rotating rod, a strike block at the bottom of the fixing frame, a connecting plate fixedly connected to the bottom of the ratchet gear, and a telescopic rod on the connecting plate; wherein, the ratchet gear is fixedly connected to the outer wall of the rotating rod, the strike block is adapted to the ratchet gear, the telescopic rod passes through the connecting plate, the connecting plate is slidably connected to the outer wall of the telescopic rod, and the side of the telescopic rod near the ratchet gear is fixedly connected to the strike block. The limiting component prevents the rotating rod from reversing through the cooperation of the ratchet gear and the strike block and the compression of the telescopic rod, thus ensuring the fixed state of the clamping component on the measuring instrument.

[0010] Furthermore, the support includes a connecting component disposed on a fixed plate; and a pressing component mounted on the connecting component; wherein the connecting component passes through the pressing component.

[0011] Furthermore, the connecting assembly includes an electric telescopic rod mounted on a fixed plate. The output shaft of the electric telescopic rod is fixedly connected to a movable plate. Several connecting rods are arranged below the fixed plate. The electric telescopic rod passes through the fixed plate, and its outer wall is fixedly connected to the fixed plate. The sides of the several connecting rods that are close to each other are respectively fixedly connected to several support legs. The connecting assembly drives the movable plate to move through the electric telescopic rod. The movable plate is connected to the support legs through the connecting rods, providing power and a connection basis for the action of the pressing assembly.

[0012] Furthermore, the pressing assembly includes movable plates respectively mounted on several connecting rods, each movable plate having a support block, each support block having a damper fixedly connected to the side near the movable plate, and each movable plate having a hinged second plate hinged to it. The connecting rods pass through the movable plates, the movable plates are rotatably connected to the outer walls of the connecting rods, the dampers are fixedly connected to the movable plates on the side away from the support blocks, and the hinged second plates are hinged to the movable plate on the side near the electric telescopic rod. Driven by the connecting assembly, the movable plates rotate around the connecting rods, placing the support blocks on a flat surface. The dampers buffer the downward pressure, thereby increasing the support area of ​​the support leg.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting a fixing part, when in use, turn the handle, and the handle drives the rotating plate to rotate through the rotating rod. When the rotating plate rotates, the hinge plate and the clamping block cooperate with each other and move towards the measuring instrument along the sliding groove on the sliding plate until the measuring instrument is fixed. Release the handle, and at this time, the ratchet on the rotating rod cooperates with the impact block. Through the compression of the telescopic rod, the rotating rod is prevented from reversing. When using the measuring instrument for water conservancy surveying, it forms a wrap-around fixation for the measuring instrument, avoiding deviation of the measurement position due to uncertain factors in the water conservancy surveying scenario, and improving the accuracy of the measurement data.

[0015] 2. After the measuring instrument is fixed by setting up the support, the electric telescopic rod is started. The electric telescopic rod drives the moving plate to move. When the moving plate moves, the hinge plate drives the movable plate to move around the connecting rod until the support block is placed on the plane. The damper is used to buffer the downward pressure when lowering, thereby increasing the support area of ​​the support leg. When using the measuring instrument for water conservancy surveying, the increased support area of ​​the measuring instrument can prevent the support leg from shifting due to water flow and other impacts, thus improving the stability of the measurement data.
