[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 2 The utility model provides an embodiment: a measuring frame for water conservancy construction management, including a top plate 1, the top end of the inner wall of the top plate 1 is rotatably connected to a clamping assembly for providing a clamping effect, the clamping assembly includes a turntable 2, the outer bottom end of the turntable 2 is rotatably connected to the top end of the inner wall of the top plate 1, and the top end of the turntable 2 is fixedly connected to a plurality of side rings 3. The turntable 2 here provides stable support for the side rings 3, and the inner side of the side ring 3 is slidably connected to a plurality of support columns, and the top end of the turntable 2 is slidably connected to a plurality of inner rings 4. The outer sleeve of the support column is provided with a spring 5. Here, under the action of the support column, it is ensured that the spring 5 will not bend laterally during extension and contraction, resulting in rupture.

[0033] Reference Figures 2 to 4 One end of the spring 15 is fixedly connected to one side of the side ring 3, and the other end of the spring 15 is fixedly connected to one side of the inner ring 4. The side ring 3 and the inner ring 4 here provide stable support for the spring 15. The top of the clamping assembly is detachably connected to a measuring device 6. The measuring device 6 here can perform right-angle measurements on the buildings of the water conservancy project to ensure the verticality of the buildings. The bottom end of the measuring device 6 is detachably connected to the top of the turntable 2. The inner wall of the top plate 1 is rotatably connected to a gear ring 17. The top plate 1 here provides stable support for the gear ring 17. The inner wall of the clamping assembly is rotatably connected to a rotating rod 8. The outside of the rotating rod 8 is rotatably connected to the inner wall of the turntable 2. The right side of the rotating rod 8 is fixedly connected to a pull rod 9. When the pull rod 9 is pulled, the rotating rod 8 here can be driven to rotate. The outside of the rotating rod 8 is fixedly connected to two elliptical blocks 10. The outside of the elliptical blocks 10 is rotatably connected to the inner wall of the bottom end of the turntable 2.

[0034] When the rotating rod 8 rotates, it can drive the two elliptical blocks 10 to rotate. An L-shaped groove 11 is provided inside the elliptical block 10, and the inner wall of the L-shaped groove 11 is slidably connected to a sliding rod 12. The bottom ends of the two sliding rods 12 are fixedly connected to a gear ring 2 13. When the elliptical block 10 rotates, the L-shaped groove 11 provided inside it will rotate accordingly. At the same time, because the pull rod 9 here is not perpendicular to the top plate 1, the L-shaped groove 11 will be tilted at a certain angle when it rotates, so that the sliding rod 12 sliding on its inner wall slides from the long axis side to the short axis side, further driving the gear ring 1 7 at its bottom end to move upward. The gear ring 1 7 is meshed with the gear ring 2 13. The outside of the gear ring 2 13 is slidably connected to the inner wall of the turntable 2. When the gear ring 1 7 moves up, it will disengage from the gear ring 2 13. At this time, the turntable 2 can be rotated, thereby driving the measuring device 6 at the top to adjust the angle.

[0035] Reference Figure 3 and Figure 5 The bottom end of the top plate 1 is rotatably connected to a plurality of fixed components for supporting. The fixed components include an outer column 14, and the top end of the outer column 14 is rotatably connected to the bottom end of the top plate 1. The outer column 14 here can be used to support the top plate 1, and the inner wall of the outer column 14 is slidably connected to the inner column 15. The outer column 14 here provides a stable support for the inner column 15, and the top end of the inner column 15 is fixedly connected to a limiting block 16, and the outer part of the limiting block 16 is slidably connected to the inner wall of the outer column 14. The limiting block 16 here can effectively prevent the inner column 15 from accidentally detaching from the sliding inner wall of the outer column 14. A spring 2 17 is fixedly connected to one side of the inner wall of the inner column 15, and the inner wall of the inner column 15 is slidably connected to a limiting disk 18. The spring 2 17 here is in an extruded state, which can provide a reaction force for the limiting disk 18 to move it outward.

[0036] One end of the second spring 17 is fixedly connected to one side of the limit plate 18. The limit plate 18 and the inner column 15 provide stable support for the second spring 17. A button 19 is fixedly connected to the outer side of the limit plate 18. The outer portion of the button 19 is slidably connected to the inner wall of the outer column 14. The outer portion of the outer column 14 is provided with a plurality of holes for adjusting the sliding distance of the inner column 15 within the outer column 14. The outer portion of the button 19 is slidably connected to the inner wall of the inner column 15. When the device needs to be stored, the button 19 can be first pressed to squeeze the limit plate 18 and the second spring 17, and the second spring 17 is squeezed harder, thereby providing a stronger reaction force. When the button 19 is pressed against the inner wall of the inner column 15, the inner column 15 is pulled to move toward the inner wall of the outer column 14. When it moves to the innermost part, the button 19 will pop out of the hole under the action of the second spring 17, completing the engagement.

[0037] The outer top end of the outer column 14 is rotatably connected to a Velcro strap 20, and the Velcro strap 20 here can bundle the stored outer columns 14 together. The bottom end of the inner column 15 is rotatably connected to a rotating block 21, and the bottom end of the rotating block 21 is rotatably connected to a rubber pad 22. The rotating block 21 and the rubber pad 22 here allow this device to stand stably on the ground no matter what angle it is unfolded to.

[0038] Working principle: First, press the measuring device 6, so that the inner ring 4 squeezes the spring 5, and at the same time the support column slides into the inner wall of the side ring 3. When the bottom end of the measuring device 6 contacts the top of the top plate 1, the reaction force of the spring 5 will lock the measuring device 6.

[0039] Secondly, when it is necessary to adjust the measuring angle of the measuring device 6, the pull rod 9 can be pulled to drive the rotating rod 8 and the two ellipsoidal blocks 10 to rotate. When the ellipsoidal block 10 rotates, the L-shaped groove 11 opened inside it will rotate accordingly. At the same time, because the pull rod 9 here is not perpendicular to the top plate 1, the L-shaped groove 11 will be tilted at a certain angle during rotation, causing the sliding rod 12 sliding on the inner wall to slide from the long axis side to the short axis side, further driving the gear ring 1 7 at its bottom end to move upward. When the gear ring 1 7 moves upward, it will disengage from the gear ring 2 13. At this time, the turntable 2 can be rotated, thereby driving the measuring device 6 at the top to adjust the angle.

[0040] Finally, when it is not needed, the device can be stored to reduce the space it occupies. At this time, the button 19 can be pressed first to squeeze the limit plate 18 and the spring 2 17, and the spring 2 17 can be squeezed harder to provide a stronger reaction force. When the button 19 is pressed to the inner wall of the inner column 15, the inner column 15 is pulled to move toward the inner wall of the outer column 14. When it moves to the innermost part, the button 19 here will pop out of the hole under the action of the spring 2 17, so that it is engaged. Then the Velcro strap 20 can be used to tie up the device. In addition, the rotating block 21 and the rubber pad 22 allow the device to stand stably on the ground no matter what angle it is unfolded to.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
