Description

Technical Field

[0001] This utility model relates to the field of slope detection technology, and in particular to a roadbed slope ratio detection device. Background Technology

[0002] In the design and construction of engineering projects, buildings need to be constructed with slopes of a certain gradient. Slope measurement and testing during construction is the process of transforming design into a complete building. If the slope is not properly controlled during construction, it will cause permanent defects and safety and quality accidents to the project. Therefore, it is necessary to accurately measure and test the slope of the construction project in accordance with regulations to ensure the quality and safety of the construction project.

[0003] Traditionally, to measure the cross slope of a slope or roadbed, two points on the slope or roadbed must be laid out first, and the horizontal distance and elevation difference between the two points must be measured. The slope is then calculated based on the horizontal distance and elevation difference. This method requires surveyors to use professional measuring instruments, which is time-consuming, labor-intensive, and cumbersome.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a roadbed slope ratio detection device to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a roadbed slope ratio detection device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A roadbed slope ratio detection device includes a base plate, on which a vacuum chamber is mounted. An opening groove is formed in the vacuum chamber, and an isolation ring is fixedly connected to the inner wall of the opening groove. A pad is fixedly connected to the bottom of the vacuum chamber, and a circular tube is fixedly connected to the pad. An inlet pipe is fixedly connected to the upper end of the circular tube, and a cap is fitted through the inner wall of the opening groove at the upper end of the inlet pipe. A sealing plug is also filled between the isolation ring and the inlet pipe. A colored liquid is injected into the circular tube. A fixed shaft is also fixedly connected to the vacuum chamber, and a rotating plate is rotatably sleeved on the outer wall of the fixed shaft. Two symmetrically distributed pointers are fixedly connected to the rotating plate. Multiple circumferentially evenly distributed scale lines are also provided on the vacuum chamber.

[0008] In a further technical solution, the centerlines of the fixed shaft, rotating plate, scale lines, and annular tube are collinear.

[0009] In a further technical solution, the vacuum chamber is also provided with two symmetrically distributed zero lines.

[0010] In a further technical solution, the volume of the colored liquid is half the volume of the annular tube.

[0011] A further technical solution is provided, wherein the vacuum chamber includes an outer shell, isolation blocks, an inner shell, and side plates; the bottom end of the base plate is fixedly connected to the outer shell, the inner shell is fixedly connected to the inner wall of the outer shell through multiple isolation blocks, and side plates are fixedly connected to both sides of the outer shell; a vacuum sealing space is formed between the outer shell, the inner shell, the side plates, and the isolation ring; and the inner shell, the side plates, and the sealing plug form a sealing space.

[0012] In a further technical solution, heat-conducting oil is injected into the space between the inner shell, side plate and sealing plug, and a temperature sensor and heater are provided on the inner wall of the inner shell.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] When measuring the slope ratio of a roadbed slope, the base plate is placed against the roadbed slope. The colored liquid in the annular tube becomes unbalanced due to gravity and flows within the tube until it reaches equilibrium again. Then, the pointer is rotated until it points to the surface of the colored liquid in the annular tube. The angle between the pointer and the zero line is observed through the scale. This angle is the angle between the base plate and the horizontal plane, thus allowing the roadbed slope ratio to be measured. The operation is simple and quick.

[0015] By injecting heat transfer oil into the space between the inner shell, side plates, and sealing plug, heating the heat transfer oil with a heater, and monitoring the temperature of the heat transfer oil in real time with a temperature sensor, the temperature of the colored liquid inside the annular tube is kept constant, thus avoiding volume changes in the colored liquid caused by temperature variations and preventing temperature changes from affecting measurement accuracy.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] For example, 1- Figure 4 As shown in the figure, this utility model embodiment provides a roadbed slope ratio detection device, including a base plate 1, a vacuum box 2 on the base plate 1, an opening groove 3 on the vacuum box 2, an isolation ring 4 fixedly connected to the inner wall of the opening groove 3, a pad 9 fixedly connected to the bottom of the vacuum box 2, a circular tube 8 fixedly connected to the pad 9, an inlet tube 6 fixedly connected to the upper end of the circular tube 8, a cap 7 being provided at the upper end of the inlet tube 6 passing through the inner wall of the opening groove 3, and a sealing plug 5 being filled between the isolation ring 4 and the inlet tube 6, and a colored liquid (not shown in the figure) being injected into the circular tube 8, a fixed shaft 10 fixedly connected to the vacuum box 2, a rotating plate 11 being rotatably sleeved on the outer wall of the fixed shaft 10, two symmetrically distributed pointers 12 fixedly connected to the rotating plate 11, and multiple circumferentially evenly distributed scale lines 13 being provided on the vacuum box 2.

[0025] Furthermore, the centerlines of the fixed shaft 10, rotating plate 11, scale line 13 and annular tube 8 are collinear.

[0026] Furthermore, the vacuum chamber 2 is also provided with two symmetrically distributed zero lines 14.

[0027] Furthermore, the volume of the colored liquid is half the volume of the annular tube 8. Specifically, when the base plate 1 is in a horizontal state, the plane containing the two liquid surfaces of the colored liquid in the annular tube 8 is parallel to the base plate 1, and the line connecting the two liquid surfaces of the colored liquid in the annular tube 8 coincides with the diameter of the annular tube 8.

[0028] like Figures 1-3As shown, the vacuum chamber 2 includes an outer shell 21, isolation blocks 22, an inner shell 23, and side plates 24; the bottom plate 1 is fixedly connected to the bottom of the outer shell 21, the inner shell 23 is fixedly connected to the inner wall of the outer shell 21 through multiple isolation blocks 22, and the side plates 24 are fixedly connected to both sides of the outer shell 21. A vacuum sealing space is formed between the outer shell 21, the inner shell 23, the side plates 24, and the isolation ring 4, and the inner shell 23, the side plates 24, and the sealing plug 5 form a sealed space.

[0029] Furthermore, heat transfer oil is injected into the space between the inner shell 23, the side plate 24, and the sealing plug 5. A temperature sensor and a heater are provided on the inner wall of the inner shell 23. The heat transfer oil is heated by the heater, and the temperature of the heat transfer oil is monitored in real time by the temperature sensor, thereby ensuring that the temperature of the colored liquid in the annular tube 8 is constant, thus avoiding changes in the volume of the colored liquid caused by temperature changes, and thus avoiding affecting the measurement accuracy.

[0030] In this embodiment of the invention, when measuring the slope ratio of a roadbed slope, the base plate 1 is placed against the roadbed slope. The colored liquid in the annular tube 8 becomes unbalanced due to gravity and flows within the annular tube 8 until it reaches equilibrium again. Then, the pointer 12 is rotated until it points to the surface of the colored liquid in the annular tube 8. The angle between the pointer 12 and the zero line 14 is observed through the scale line 13. This angle is the angle between the base plate 1 and the horizontal plane, thus enabling the measurement of the roadbed slope ratio. The operation is simple and quick. By injecting heat transfer oil into the space between the inner shell 23, the side plate 24, and the sealing plug 5, and heating the heat transfer oil with a heater, the temperature of the heat transfer oil is monitored in real time by a temperature sensor. This ensures that the temperature of the colored liquid in the annular tube 8 remains constant, thereby avoiding volume changes in the colored liquid due to temperature variations and thus preventing temperature changes from affecting the measurement accuracy.

[0031] The working principle of this utility model is as follows: Place the base plate 1 horizontally, then inject heat-conducting oil into the space formed by the inner shell 23, side plate 24 and sealing plug 5, and then seal the space with the sealing plug 5. Next, heat the heat-conducting oil to the set temperature by the heater, and then inject a colored liquid occupying half the volume into the annular tube 8, with the temperature of the colored liquid being the same as that of the heat-conducting oil. At this time, the two liquid levels of the colored liquid are coplanar with the zero line 14. Then, tighten the cap 7 to seal the annular tube 8, and then turn off the heater. When measuring the slope ratio of the roadbed, heat the heat-conducting oil to the set temperature by the heater, and then place the base plate 1 against the roadbed slope. The colored liquid in the annular tube 8 becomes unbalanced due to gravity and flows in the annular tube 8 until it is balanced again. Then, rotate the pointer 12 until the pointer 12 points to the liquid level of the colored liquid in the annular tube 8. Observe the angle between the pointer 12 and the zero line 14 through the scale line 13. This angle is the angle between the base plate 1 and the horizontal plane.

[0032] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
