Technical Field
[0001] This utility model relates to the field of inclinometer technology, and more specifically, to a freeze-proof rotating structure for an inclinometer. Background Technology
[0002] An inclinometer is an instrument used to accurately measure the tilt angle or slope of an object. It is widely used in civil engineering, geological exploration, and industry. In civil engineering, it can monitor slope stability and building settlement; in geological exploration, it can measure the dip angle of strata and monitor geological hazards; in industry, it assists in the installation and commissioning of mechanical equipment and the monitoring of pipeline laying. Through internal sensors and other components, it converts the tilt angle into electrical signals and other data outputs, providing crucial measurement information for various industries.
[0003] Inclinometers are typically used in conjunction with inclinometer tubes. Moisture in the soil can enter the inclinometer tube as water vapor through tiny pores in the tube wall or gaps at the joints, causing humidity. When the ambient temperature is low, this can easily lead to the guide wheels and shaft of the inclinometer freezing and becoming unable to rotate, affecting the normal operation of the inclinometer. Therefore, we propose a freeze-proof rotating structure for the inclinometer. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a freeze-proof rotating structure for inclinometers to solve the technical problem that when the current environment is not very stable, the guide wheels and shafts of the inclinometers are prone to freeze and cannot rotate.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a freeze-proof inclinometer rotating structure, including an inclinometer body and a rotating mechanism installed on the inclinometer body. The inclinometer body includes a heating pipe, a connecting pipe, a detection part, a connecting plate, and an airflow pipe. A motor is installed inside the heating pipe, and a fan blade is installed at the end of the motor's main shaft. An electric heating wire is installed inside the heating pipe below the fan blade. An air inlet is opened on the outer surface of the heating pipe. The rotating mechanism includes a mounting frame rotatably installed between the connecting plates. Guide wheels are symmetrically rotatably installed inside the mounting frame. Heating pipes are installed diagonally on the mounting frame by bolts. A metal hose is installed on the heating pipe, and the end of the metal hose is connected to the airflow pipe.
[0006] Preferably, both the heating pipe and the connecting pipe are provided with a connecting plate at their lower ends, the connecting pipe is located at the end of the connecting plate at the lower end of the heating pipe, and the detection part is located at the end of the connecting plate at the lower end of the connecting pipe.
[0007] Preferably, an airflow pipe is installed between the heating pipe and the connecting pipe, as well as at the lower end of the connecting pipe, and the airflow pipe is connected to the heating pipe and the connecting pipe.
[0008] Preferably, a mounting shaft is rotatably mounted on the connecting plate, the mounting bracket is installed between the mounting shafts, and a torsion spring is provided on the connecting plate outside the mounting shafts. The end of the torsion spring is connected to the mounting bracket, and the torsion spring keeps the mounting bracket in an inclined state.
[0009] Preferably, the heating tube has a rectangular cross-section and includes a first heating section, a bent section, a straight section, and a second heating section in sequence along its long axis. The bent section is bent outward at a 90-degree angle and located at the end of the first heating section. The straight section is bent and located at the end of the bent section, and the second heating section is located at the end of the straight section.
[0010] Preferably, the first heating part is arc-shaped along its long axis, the first heating part is semi-circular in shape, the first heating part is wrapped around the outside of the guide wheel, and the beginning of the first heating part extends beyond the horizontal position of the guide wheel. The second heating part is an annular tube with a notch, the second heating part is wrapped around the outside of the mounting shaft, and the inner walls of both the first heating part and the second heating part are provided with air vents.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the design of the heating pipe structure, by setting a motor, fan blades and electric heating wire inside the heating pipe, can generate hot air, which is transmitted to the heating pipe through the airflow pipe and metal hose to heat the guide wheel and mounting shaft. This effectively prevents the guide wheel and its shaft and mounting shaft from freezing due to low ambient temperature, ensuring that the inclinometer can rotate and be used normally in low temperature and humid environment. It solves the problem that the guide wheel and shaft of the inclinometer are prone to freezing and unable to rotate when the current environment is low and stable.
[0013] 2. This utility model also designs a heating tube structure in which the beginning of the first heating part extends beyond the horizontal position of the guide wheel, so that when the mounting bracket is tilted at a high angle, the heating tube will not touch the inner wall of the inclinometer tube. The first heating part is semi-circularly wrapped around the outside of the guide wheel and the second heating part is wrapped around the outside of the mounting shaft, so that hot air can be fully blown out to the guide wheel and the mounting shaft, ensuring the anti-freezing effect of the rotating structure. Moreover, the notch in the second heating part can also facilitate the installation and removal of the heating tube. Attached Figure Description

Detailed Implementation
[0022] like Figures 1 to 7 As shown, this utility model relates to a freeze-proof inclinometer rotating structure, including an inclinometer body 100 and a rotating mechanism 200 provided on the inclinometer body 100. The inclinometer body 100 includes a heating pipe 101, a connecting pipe 102, a detection part 103, a connecting plate 104, and an airflow pipe 105. A motor 106 is provided inside the heating pipe 101, and a fan blade 107 is installed at the end of the main shaft of the motor 106. An electric heating wire 108 is provided inside the heating pipe 101 below the fan blade 107. An air inlet is provided on the outer surface of the heating pipe 101. The rotating mechanism 200 includes a mounting bracket 201 rotatably mounted between the connecting plates 104. Guide wheels 202 are symmetrically rotatably mounted inside the mounting bracket 201. A heating pipe 205 is diagonally mounted on the mounting bracket 201 by bolts. A metal hose 206 is provided on the heating pipe 205, and the end of the metal hose 206 is connected to the airflow pipe 105. This utility model is equipped with an anti-freezing structure, which effectively prevents the guide wheel 202 and its shaft and mounting shaft 203 from freezing due to low ambient temperature, ensuring that the inclinometer can rotate and be used normally in low temperature and humid environment, and preventing the inclinometer from being affected by the low temperature environment.
[0023] Specifically, both the heating pipe 101 and the connecting pipe 102 are equipped with a connecting plate 104 at their lower ends. The connecting pipe 102 is located at the end of the connecting plate 104 at the lower end of the heating pipe 101, and the detection unit 103 is located at the end of the connecting plate 104 at the lower end of the connecting pipe 102. The connecting plate 104 is used for connecting the various parts of the inclinometer.
[0024] Furthermore, airflow pipes 105 are installed between the heating pipe 101 and the connecting pipe 102, as well as at the lower end of the connecting pipe 102. The airflow pipes 105 are connected to the heating pipe 101 and the connecting pipe 102. The installation of the airflow pipes 105 allows the heating pipe 101 and the connecting pipe 102 to connect, enabling airflow.
[0025] It is worth noting that a mounting shaft 203 is rotatably mounted on the connecting plate 104, and a mounting bracket 201 is installed between the mounting shafts 203. A torsion spring 204 is provided on the connecting plate 104 outside the mounting shafts 203, and the end of the torsion spring 204 is connected to the mounting bracket 201. The torsion spring 204 keeps the mounting bracket 201 in an inclined state. The torsion spring 204 can support the mounting bracket 201, allowing the inclination of the guide wheel 202 to be adjusted, which can be used with inclinometers in inclinometer tubes of different diameters.
[0026] It is worth noting that the heating tube 205 has a rectangular cross-section. The heating tube 205 includes, along its long axis, a first heating section 2051, a bent section 2052, a straight section 2053, and a second heating section 2054. The bent section 2052 is bent outward at a 90-degree angle and located at the end of the first heating section 2051. The straight section 2053 is bent and located at the end of the bent section 2052. The second heating section 2054 is located at the end of the straight section 2053. The bending of the bent section 2052 and the straight section 2053 allows the heating tube 205 to adapt to the shape of the rotating structure, thereby positioning the first heating section 2051 and the second heating section 2054 on the outside of the guide wheel 202 and the mounting shaft 203, respectively.
[0027] It is worth noting that the first heating element 2051 is arc-shaped along its long axis and is semi-circular in shape. The first heating element 2051 wraps around the outside of the guide wheel 202, with its starting end extending beyond the horizontal position of the guide wheel 202. The second heating element 2054 is an annular tube with a notch, wrapping around the outside of the mounting shaft 203. Both the inner walls of the first and second heating elements 2051 and 2054 have air vents. The fact that the starting end of the first heating element 2051 extends beyond the horizontal position of the guide wheel 202 ensures that the heating tube 205 will not touch the inner wall of the inclinometer tube when the mounting bracket 201 is tilted at a high angle. The semi-circular shape of the first heating element 2051 wrapping around the outside of the guide wheel 202 and the second heating element 2054 wrapping around the outside of the mounting shaft 203 allow hot air to be fully blown onto the guide wheel 202 and the mounting shaft 203, thereby preventing freezing of the rotating structure.
[0028] Working Principle: This embodiment provides a freeze-proof rotating structure for an inclinometer. During use, the inclinometer is placed in the inclinometer tube. The mounting bracket 201 is kept tilted by the torsion spring 204, allowing the guide wheel 202 to better fit against the tube wall. When the inclinometer descends, the guide wheel 202 rolls on the tube wall, and the detection unit 103 performs the detection. During use, if the ambient temperature is low and may cause the guide wheel 202 and shaft of the inclinometer to freeze, the motor 106 and electric heating wire 108 inside the heating pipe 101 are activated. The motor 106 drives the fan blade 107 to rotate, and cold air from the outside enters through the air inlet on the outer surface of the heating pipe 101. After being heated by the electric heating wire 108, it becomes hot air. The hot air flows through the airflow pipe 105 at the lower end of the connecting pipe 102 and between the heating pipe 101 and the connecting pipe 102, towards the metal. Hot air enters the heating tube 205 through the flexible hose 206. The hot air first reaches the first heating section 2051. Since the first heating section 2051 is semi-circular and wraps around the outside of the guide wheel 202, the hot air is blown out from the air outlet on its inner wall, heating the guide wheel 202 and its shaft. This helps the guide wheel 202 bond the inclinometer tube and prevents the shaft of the guide wheel 202 from freezing. At the same time, the hot air flows along the bend 2052 and straight section 2053 of the heating tube 205 to the second heating section 2054, wrapping around the outside of the mounting shaft 203. The hot air is blown out from the air outlet on its inner wall, heating the mounting shaft 203 and preventing it from freezing. The heating tube 205 continuously provides heat to the guide wheel 202 and the mounting shaft 203, effectively preventing freezing caused by low ambient temperature and ensuring the normal rotation and measurement operation of the inclinometer.
