DETAILED DESCRIPTION

[0030] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 9 The present invention provides two technical solutions, which specifically include the following embodiments:

[0032] Example 1: Reference Figure 1 , Figure 2 A portable slope measuring device for water conservancy project construction includes a handheld measuring frame 1, both ends of the handheld measuring frame 1 are rotatably connected with moving wheels 102, an annular limit frame 4 is fixedly installed on the outside of the handheld measuring frame 1, a rotating shaft 402 is fixed inside the annular limit frame 4, and a plurality of transmission connecting rods 7 are rotatably connected to the outside of the rotating shaft 402, and the length of the transmission connecting rod 7 exceeds the moving wheel 102, which can be used in an inclined state during measurement. During surveying, the handheld measuring frame 1 is parallel to the side to be measured, so that the moving wheel 102 contacts with the surface to be measured, and the plurality of transmission connecting rods 7 are tilted to one side when placed, and then the survey is realized by pushing the handheld measuring frame 1 to move;

[0033] Specifically, a plurality of levels are installed inside the handheld measuring frame 1 to ensure that the handheld measuring frame 1 is in a horizontal state during placement and movement. The levels are existing devices and are not shown in the figure.

[0034] For further reference, Figure 1-Figure 9, the transmission connecting rod 7 extends to one end of the handheld measuring frame 1 and is fixedly installed with an arc-shaped transmission rod 8, and the end of the arc-shaped transmission rod 8 is fixed with a sealing end 801, and a plurality of arc-shaped outer sleeves 5 are fixed inside the handheld measuring frame 1, and the plurality of sealing ends 801 are respectively located inside the corresponding arc-shaped outer sleeves 5 and are slidably connected thereto, an air bag 9 is provided inside the arc-shaped outer sleeve 5, and the end of the air bag 9 is fixedly connected with a display rod 6 that is interconnected, and a liquid is provided inside the air bag 9, which can enter the display rod 6 by being pressurized, and the end of the display rod 6 passes through the corresponding arc-shaped outer sleeve 5 and remains perpendicular thereto. When the handheld measuring frame 1 is parallel to the side to be measured, so that the moving wheel 102 is in contact with the side to be measured, at this time, the plurality of transmission connecting rods The rod 7 can be compressed by contacting with the side surface to be treated, and rotates along the rotating shaft 402 inside the annular limit frame 4. The arc-shaped transmission rod 8 at the end can be driven to move by the rotation of the transmission connecting rod 7, so that the sealing end 801 is pushed into the arc-shaped outer sleeve 5. At this time, the airbag 9 is compressed, so that the internal liquid enters the inside of the display rod 6. As the handheld measuring frame 1 moves along the side surface to be treated, when the end of the transmission connecting rod 7 encounters a convex position, the rotation angle of the transmission connecting rod 7 increases, and when the end of the transmission connecting rod 7 encounters a concave position, the rotation angle of the transmission connecting rod 7 decreases. As the rotation angle of the transmission connecting rod 7 increases or decreases, the pressure of the airbag 9 can be changed, thereby changing the liquid level inside the display rod 6, which is convenient for observation.

[0035] For further reference, Figure 8 , Fig. 9 The end of the transmission connecting rod 7 away from the handheld measuring frame 1 is rotatably connected with a spherical body 703, and the spherical body 703 is used to contact the side surface to be measured during the survey process. A support spring 702 is fixedly installed between the transmission connecting rod 7 and the inner wall of the handheld measuring frame 1. The support spring 702 is used to drive the transmission connecting rod 7 to reset. When the survey is carried out, as the spherical body 703 contacts the side surface to be measured, the friction between the handheld measuring frame 1 and the surface to be measured can be reduced during the survey process, thereby ensuring the survey effect;

[0036] Furthermore, the straight-line distances from the arc-shaped transmission rod 8 and the sealing end 801, as well as the inner side of the arc-shaped outer sleeve 5 to the central axis of the rotating shaft 402 are all the same, so that when the transmission connecting rod 7 is forced to rotate along the rotating shaft 402, the sealing end 801 can be pushed into the arc-shaped outer sleeve 5 through the arc-shaped transmission rod 8. By keeping the arc-shaped transmission rod 8 and the sealing end 801, and the arc-shaped outer sleeve 5 and the rotating shaft 402 coaxial, when the transmission connecting rod 7 is forced to rotate along the rotating shaft 402, the arc-shaped transmission rod 8 can be pushed to operate, so that the sealing end 801 slides inside the arc-shaped outer sleeve 5, thereby ensuring the squeezing effect on the airbag 9;

[0037] Specifically, a through hole 701 is formed inside each of the plurality of transmission connecting rods 7, and the rotating shaft 402 passes through the through hole 701 and is rotatably connected thereto;

[0038] Specifically, a plurality of connecting and fixing rods 401 are fixed on both sides of the annular limiting frame 4, and the annular limiting frame 4 is fixedly connected to the handheld measuring frame 1 through the plurality of connecting and fixing rods 401;

During surveying, the handheld measuring frame 1 is parallel to the side to be measured, so that the moving wheel 102 contacts with the surface to be measured, and the plurality of transmission connecting rods 7 are tilted to one side when placed, and then the survey is realized by pushing the handheld measuring frame 1 to move;

When the handheld measuring frame 1 is parallel to the side to be measured, so that the moving wheel 102 is in contact with the side to be measured, at this time, the plurality of transmission connecting rods The rod 7 can be compressed by contacting with the side surface to be treated, and rotates along the rotating shaft 402 inside the annular limit frame 4. The arc-shaped transmission rod 8 at the end can be driven to move by the rotation of the transmission connecting rod 7, so that the sealing end 801 is pushed into the arc-shaped outer sleeve 5. At this time, the airbag 9 is compressed, so that the internal liquid enters the inside of the display rod 6. As the handheld measuring frame 1 moves along the side surface to be treated, when the end of the transmission connecting rod 7 encounters a convex position, the rotation angle of the transmission connecting rod 7 increases, and when the end of the transmission connecting rod 7 encounters a concave position, the rotation angle of the transmission connecting rod 7 decreases. As the rotation angle of the transmission connecting rod 7 increases or decreases, the pressure of the airbag 9 can be changed, thereby changing the liquid level inside the display rod 6, which is convenient for observation.

The support spring 702 is used to drive the transmission connecting rod 7 to reset. When the survey is carried out, as the spherical body 703 contacts the side surface to be measured, the friction between the handheld measuring frame 1 and the surface to be measured can be reduced during the survey process, thereby ensuring the survey effect;

[0044] Furthermore, the straight-line distances from the arc-shaped transmission rod 8 and the sealing end 801, as well as the inner side of the arc-shaped outer sleeve 5 to the central axis of the rotating shaft 402 are all the same, so that when the transmission connecting rod 7 is forced to rotate along the rotating shaft 402, the sealing end 801 can be pushed into the arc-shaped outer sleeve 5 through the arc-shaped transmission rod 8. By keeping the arc-shaped transmission rod 8 and the sealing end 801, and the arc-shaped outer sleeve 5 and the rotating shaft 402 coaxial, when the transmission connecting rod 7 is forced to rotate along the rotating shaft 402, the arc-shaped transmission rod 8 can be pushed to operate, so that the sealing end 801 slides inside the arc-shaped outer sleeve 5, thereby ensuring the squeezing effect on the airbag 9;
