Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, and in particular relates to a plane tilt angle detection device. Background Technology

[0002] In engineering construction, whether the building is level is crucial to the safety and reliability of the entire project, which requires testing of the completed walls and panels.

[0003] Traditional leveling methods typically rely on manually operated level instruments or spirit levels. While these methods can meet basic measurement needs to some extent, they suffer from problems such as cumbersome operation, limited measurement accuracy, and significant susceptibility to environmental factors. Especially in complex or special construction environments, such as working at heights, confined spaces, or irregular surfaces, traditional leveling tools often struggle to complete measurement tasks accurately and quickly. Furthermore, with the continuous advancement of modern construction technology and the increasing scale of projects, the requirements for measurement accuracy and efficiency are also rising, making traditional leveling methods inadequate for the needs of actual construction. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a plane tilt angle detection device.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a plane tilt angle detection device, comprising a box structure, a movable support column on the bottom wall of the box structure, a gravity block above the support column, a plurality of force-bearing columns on the outer periphery of the gravity block, a gap between the gravity block and the plurality of force-bearing columns, the other ends of the plurality of force-bearing columns being connected to the side wall of the box structure respectively, strain gauges being mounted on the surface of the plurality of force-bearing columns respectively, wires extending to the outside of the box structure being mounted on the plurality of strain gauges, and a top cover being mounted on the upper end of the box structure.

[0006] By adopting the above technical solution, the box structure, as the main body of the entire plane tilt angle detection device, provides a stable installation environment for the internal components. The strain gauges installed on the inner side wall of the box structure can sensitively capture the minute deformation caused by the change of plane tilt angle, and then transmit the signal to the external processing equipment through the wire to realize the detection of plane tilt angle. In addition, the box is small in size, easy to carry and install in various environments and on various equipment, and has a wide range of applications.

[0007] Optionally, the box structure includes a base plate, which is square, and side plates are provided on the base plate. The side walls of the base plate have mating notches, and the side walls at both ends of the mating notches are respectively provided with limiting grooves. The lower ends of several side plates are respectively equipped with sockets that are inserted into several mating notches, and the two sides of the sockets are respectively equipped with limiting strips that are connected to the limiting grooves.

[0008] By adopting the above technical solution, the base plate is square, and the side plates are installed around the base plate. Through the insertion method of the notch and socket, as well as the cooperation of the limiting groove and limiting strip, the stable assembly of the box structure is achieved. This design not only improves the convenience of assembly, but also ensures the overall strength and stability of the box structure.

[0009] Optionally, a protrusion and a groove are provided between adjacent side plates, and the protrusion and the groove are connected to each other.

[0010] By adopting the above technical solution, the connection between the protrusion and the groove further enhances the connection strength between adjacent side plates, preventing structural instability caused by loose side plates. This design helps to improve the overall rigidity and durability of the entire box structure.

[0011] Optionally, the box structure includes a base plate, which is circular, and a sleeve is provided on the base plate. The sleeve is connected to the base plate by fixing bolts or adhesive.

[0012] By adopting the above technical solution, the base plate is circular, and the sleeve is installed on the outer periphery of the base plate and connected by fixing bolts. This design makes the box structure more compact, and the use of fixing bolts ensures a firm connection between the sleeve and the base plate, improving the stability and load-bearing capacity of the box structure.

[0013] Optionally, the two pairs of force-bearing columns are circular or rectangular in shape, and the two pairs of force-bearing columns are symmetrically distributed with the center point of the box structure as the base point.

[0014] By adopting the above technical solution, the shape of the stress column is circular or rectangular, and it is symmetrically distributed with the center point of the box structure as the base point. This design is not only aesthetically pleasing, but also ensures that the stress column can be uniformly stressed when the plane tilt angle changes, thereby improving the accuracy and reliability of strain gauge detection.

[0015] Optionally, the bottom wall of the box structure is provided with a mounting groove, which is located at the center of the bottom wall of the box structure.

[0016] By adopting the above technical solution, the mounting groove is located at the center of the bottom wall of the box structure, which facilitates the installation of the support column. At the same time, the design of the mounting groove also helps to improve the stability of the support column and ensure its accuracy in the plane tilt angle detection process.

[0017] Optionally, the lower end of the support column is conical.

[0018] By adopting the above technical solution, the lower end of the conical support column can better adapt to uneven installation surfaces. Even on slightly inclined or uneven ground, the conical design can ensure good contact between the support column and the base plate, preventing the device from affecting the detection accuracy due to shaking. Furthermore, the conical design ensures that the gravity block has angular freedom in the direction of gravity deflection when the plane tilt angle changes, thus ensuring that the overall force change caused by the gravity direction deflection is fully reflected in the lateral rod strain.

[0019] Optionally, the gravity block is rectangular or cylindrical, and the gap between the gravity block and the plurality of force-bearing columns is 0.1mm-0.5mm.

[0020] By adopting the above technical solution, a gap of 0.1mm-0.5mm is provided between the outer wall of the gravity block and the force-bearing column. This design not only avoids direct contact and friction between the gravity block and the force-bearing column, but also ensures that there is no prestress in the device and does not have a significant impact on the measurement process itself.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This device uses the gravity of the central weight and the support of the support rods to maintain the weight's freedom at the turning angle, preventing interference from forces or bending moments perpendicular to the axial direction at the bottom. This ensures the accuracy of data measurement. The design of the gravity block allows it to apply pressure evenly to the surrounding rods. These minute pressure changes are captured by strain gauges, indirectly measuring the plane tilt angle.

[0023] 2. Compared with traditional leveling instruments or spirit levels, this device is easier to operate. Users only need to place the device on the plane to be measured, and can obtain the tilt angle information by reading the data output by the strain gauge. Therefore, even under conditions of large changes in the external environment, the stability and reliability of the measurement data can be guaranteed.

[0024] 3. This device adopts a modular design, and the box structure is easy to assemble and disassemble, making it convenient for users to carry out daily maintenance and upkeep. At the same time, the simple structural design also reduces production costs, making the device more competitive in the market. Attached Figure Description

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] like Figure 1 As shown in Figure 3, the specific solution of the embodiment is as follows: A plane tilt angle detection device includes a box structure 1, the geometric dimensions of which are 10cm³-80cm³. The box structure 1 serves as the main structure of the entire plane tilt angle detection device, providing a stable installation platform for other components and protecting the internal components from the influence of the external environment. The box structure 1 is assembled from transparent acrylic sheets. By using transparent acrylic sheets, users can intuitively observe the internal working conditions of the device. At the same time, acrylic sheets have good impact resistance and weather resistance, ensuring the durability of the device. Furthermore, acrylic sheet materials and processing costs are low, and processing precision is high, which helps to improve the accuracy and economic benefits of the device.

[0032] The box structure 1 includes a base plate 101 and side plates 102 installed around the base plate 101. The base plate 101 is square and serves as the bottom support of the box structure 1, providing a stable mounting base for other components. The square shape of the base plate 101 facilitates the placement and positioning of the device. The side plates 102 are used to enclose the box structure 1, providing mounting space and protection for internal components.

[0033] The base plate 101 has a notch 103 on its side wall, and a limiting groove is formed on the side wall at both ends of the notch 103. A socket 104 is installed at the lower end of each of the side plates 102, which is inserted into the notch 103. The fit between the socket 104 and the notch 103 strengthens the stable connection between the base plate 101 and the side plates 102. The fit between the base plate 101 and the side plates 102 forms a complete box structure 1, providing good sealing and stability for the device. Limiting strips connected to the limiting grooves are installed on both sides of the socket 104. A protrusion 105 and a groove 1 are provided between adjacent side plates 102. 06. The fit between the limiting groove and the limiting strip can prevent the docking notch 103 from falling off the socket 104. The fit between the docking notch 103 and the limiting groove makes the connection between the bottom plate 101 and the side plate 102 more stable, improving the overall strength of the device. The protruding block 105 and the groove 106 are connected to each other. The design of the protruding block 105 and the groove 106 makes the connection between adjacent side plates 102 more tight, improving the overall stability of the box structure 1. The bottom wall of the box structure 1 is provided with an installation groove 107. The installation groove 107 is located at the center of the bottom wall of the box structure 1. The installation groove 107 is used to install the support column 5.

[0034] The inner wall of the box structure 1 is provided with two pairs of force-bearing columns 2. The force-bearing columns 2 are made of PVC rods or pressure-sensitive materials. The two pairs of force-bearing columns 2 are circular or rectangular in shape and are symmetrically distributed with the center point of the box structure 1 as the base point. Strain gauges 3 are installed on the surface of the two pairs of force-bearing columns 2 respectively. The strain gauges 3 are installed on the surface of the force-bearing columns 2 to detect the deformation of the force-bearing columns 2, thereby calculating the tilt angle of the plane. The cooperation between the force-bearing columns 2 and the strain gauges 3 enables the device to detect the tilt angle of the plane, improving the accuracy of the detection.

[0035] Two pairs of strain gauges 3 are equipped with wires 4 extending to the outside of the housing structure 1. The wires 4 can transmit the signals on the strain gauges 3 to external processing equipment. The upper end of the housing structure 1 is provided with a notch for the wires 4 to pass through. Through the cooperation of the wires 4 and the notch, the device can transmit the detected signals to the external processing equipment, realizing real-time data processing and display.

[0036] The bottom wall of the box structure 1 is provided with a support column 5. The lower end of the support column is made of wear-resistant material. The lower end of the support column 5 is conical. A rolling ball can be installed at the lower end of the support column 5, allowing the lower end of the support column 5 to rotate freely. The lower end of the support column 5 is inserted into the mounting groove 107, which is a conical groove. A gravity block 6 is installed at the end of the support column 5 away from the bottom wall of the box structure 1. The cooperation between the support column 5 and the gravity block 6 allows the device to maintain a stable posture. At the same time, the design of the gravity block 6 increases the stability of the device and improves the accuracy of detection. The gravity block 6 is rectangular or cylindrical. There is a gap of 0.1mm-0.5mm between the outer wall of the gravity block 6 and several of the force-bearing columns 2. A top cover 7 is installed at the upper end of the box structure 1. The top cover 7 is used to close the box structure 1 and protect the internal components. The design of the top cover 7 gives the device good sealing and protection, avoiding the influence of external factors on the internal components of the device.

[0037] In some technical solutions, the box structure 1 includes a base plate 101 and a sleeve installed on the outer periphery of the base plate 101. The base plate 101 is circular, and the sleeve is connected to the base plate 101 by fixing bolts.

[0038] The working principle of the above embodiments is as follows:

[0039] When the plane tilt angle detection device is in use, if it is placed on a plane with an inclination angle, gravity will cause the gravity block 6 to tilt towards one end of the force-bearing column 2. The end of the force-bearing column 2 will be subjected to the pressure of the gravity block 6, resulting in deformation. The strain gauge 3 on the force-bearing column 2 sensitively captures the minute deformation of the force-bearing column 2 under the gravitational deflection. The resistance value of the strain gauge 3 changes, and this change is converted into a corresponding electrical signal output. By reading these electrical signals, we can obtain the magnitude of the force on the force-bearing column 2 at a specific tilt angle. Using known material parameters and the readings of the strain gauge 3... Based on the mechanical properties of the material, the relationship between the deformation of the stressed column 2 and the force it is subjected to is established. The force on the stressed column 2 under the deflection of gravity is calculated. Finally, using the parallelogram principle of forces, the direction of gravity deflection is inferred from the force on the stressed column 2, and then the inclination angle of the plane is solved. The parallelogram principle of forces states that when an object is subjected to multiple forces, it can be regarded as the diagonal of a parallelogram, and each force is regarded as an adjacent side of the parallelogram. By measuring and calculating the direction and magnitude of these forces, we can determine the shape of the parallelogram, and thus solve for the inclination angle of the object.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
