Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering, in particular to a level testing instrument for water conservancy engineering survey. Background Art

[0002] During the construction of water conservancy projects, in order to ensure the quality of the project, it may be necessary to test whether some components are level during the survey of the water conservancy project to ensure that the components are level during the construction process. At this time, an infrared level meter is needed.

[0003] For example, the utility model with application number 202321859824.5 discloses an outdoor speaker that is easy to store. The motor is fixed in the shell, the screw rod is fixed on the output end of the motor, the outer side of the screw rod is connected to the threaded sleeve through a thread, and the motor is started to drive the screw rod to rotate, so that threaded movement occurs between the screw rod and the threaded sleeve, and the threaded sleeve moves. The movement of the threaded sleeve drives the base to move, and the infrared level body moves to complete the height adjustment. The slide plate can be pulled to drive the ejector pin to slide out of the slot, thereby releasing the limit on the pin. At this time, the infrared level body can be moved to complete the disassembly.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] Existing level testers usually require handheld devices for use, but the weight of the equipment is large, so it is a heavy burden on the user. At the same time, due to manual use, it is difficult to ensure that the level tester itself is in a horizontal state, which easily leads to errors in the detection of the horizontal state of the components.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a level testing instrument for water conservancy engineering survey is proposed. Utility Model Content

[0007] The utility model aims to provide a level tester for water conservancy engineering survey to solve the problems raised in the above-mentioned background technology.

[0011] Furthermore, universal wheels are arranged at the four corners of the bottom of the base, and a telescopic column is arranged at the bottom of the spherical connector, and the telescopic column forms a rotating connection structure with the heightening plate through the spherical connector. The tester body can be partially fine-tuned by adjusting the telescopic column to ensure the horizontal state of the tester body.

[0012] Furthermore, the adjustment mechanism includes a two-way adjustment screw rod, which is rotatably connected to the inner center of the adjustment slot, a rotating bevel gear is fixedly connected to the outer side of the center of the two-way adjustment screw rod, one end of the rotating bevel gear is meshed with a linkage bevel gear, a rotating shaft is arranged at the bottom center of the linkage bevel gear, and a rotating motor is arranged at the bottom of the rotating shaft. The height of the tester body can be adjusted by rotating the two-way adjustment screw rod in cooperation with the lifting frame.

[0013] Furthermore, both ends of the bidirectional adjustment screw rod are threadedly connected to a movable plate, both ends of the adjustment slot are fixedly connected to limit rods, both ends of the top of the movable plate are connected to a lifting frame, and the top of the lifting frame is hinged to the bottom of the height-enhancing plate. The height of the height-enhancing plate and the tester body can be adjusted by extending the lifting frame.

[0014] Furthermore, the detection mechanism includes a rotating adjustment head, the rotating adjustment head is fixedly connected to the top of the telescopic column, the top of the rotating adjustment head is sleeved with an adjustment sleeve, and the top of the adjustment sleeve is fixedly connected to the bottom of the mounting plate.

The horizontal state of the tester body can be detected by the movement of the balls inside the detection box.

[0016] Furthermore, the distance between the annular rail and the top of the inner cavity of the detection box is smaller than the diameter of the ball. Such an arrangement can prevent the ball from escaping from the annular rail.

[0017] The utility model provides a level tester for water conservancy engineering survey, which has the following beneficial effects:

[0018] First, the utility model, through the setting of the adjustment mechanism, drives the movable plate to move relatively by rotating the bidirectional adjustment screw rod, and through the cooperation of the movable plate and the lifting frame, can adjust the distance between the base and the height-increasing plate. Such a setting can adjust the height of the tester body and meet the requirements of detecting whether components of different heights are level.

[0019] Secondly, the utility model sets up a detection mechanism. Before detecting whether the components are level, it is necessary to first determine the level of the tester body. When the base is stationary, the horizontal state of the tester body is detected according to the position of the ball in the detection box. Then, according to the state of the ball, the height of the telescopic column combination is adjusted by the adjustment buckle. During the adjustment process, the state of the ball is monitored at any time to adjust the level of the tester body. BRIEF DESCRIPTION OF THE DRAWINGS

Universal wheels 7 are arranged at the four corners of the bottom of the base 1, and a telescopic column 8 is arranged at the bottom of the spherical connector 3, and the telescopic column 8 forms a rotating connection structure with the heightening plate 2 through the spherical connector 3.

[0027] In this embodiment: first, the position of the tester body 5 is moved by the universal wheel 7, and no handheld device is required. During the inspection, components at different positions are inspected by the test heads 6 on both sides according to the positions of the components. The setting of the spherical connector 3 can ensure that the rotation angle range of the telescopic column 8 is expanded, and the height of the heightening plate 2 can be adjusted by adjusting the height of the heightening plate 2.

[0028] In the first embodiment, since the heights of the components to be tested are different, the height of the tester body 5 needs to be adjusted, and the specific operation is as follows:

[0029] like Figure 3 and Figure 4 As shown, the adjustment mechanism includes a bidirectional adjustment screw 9, which is rotatably connected to the inner center of the adjustment slot, and a rotating bevel gear 10 is fixedly connected to the outer side of the center of the bidirectional adjustment screw 9, and a linkage bevel gear 11 is meshed with one end of the rotating bevel gear 10, and a rotating shaft is provided at the bottom center of the linkage bevel gear 11, and a rotating motor 12 is provided at the bottom of the rotating shaft.
