Description

Technical Field

[0001] The invention relates to the field of strength detection, and in particular to a dam body strength detector and a detection method for water conservancy projects. Background Art

[0002] As an important part of infrastructure construction, water conservancy projects play a key role in flood control, irrigation, power generation and other aspects. Among them, the dam body, as the main structure of the water conservancy project, its strength is directly related to the safety and durability of the project. Therefore, accurate detection of the dam body strength is an important prerequisite for ensuring the safe operation of the water conservancy project. The existing technology generally adopts a multi-point monitoring method for strength detection. During multi-point detection, the detection equipment selects the detection points at the same time. Therefore, there is no fixed fixing mechanism to provide a stable detection platform for the detection equipment, which makes the force direction of the detection equipment deviate during each detection, which is prone to errors, and manual measurement is required during each detection, which is too inconvenient. Summary of the invention

[0003] The invention provides a dam strength detector and a detection method for water conservancy projects, which overcome the shortcomings described in the background technology.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A dam strength detector for water conservancy projects, comprising a fixing frame, a detection device, and a motor, wherein the detection device is mounted on the fixing frame, the fixing frame comprises a pressing frame and a stabilizing frame, the lower end of the pressing frame is swungly connected to the stabilizing frame through a hinge, and the stabilizing frame is mounted on the output shaft of the motor, so that the pressing frame and the stabilizing frame are pressed against the dam body by rotating the stabilizing frame; The middle parts of the pressing frame and the stabilizing frame are both provided with openings for the detection device to detect the dam body. The edge of the pressing frame facing the stabilizing frame is provided with outwardly protruding indicator rods. The indicator rods are arranged equidistantly along the edge of the pressing frame, and the length of the indicator rods gradually shortens from top to bottom. When the pressing frame is pushed toward the stabilizing frame, all the indicator rods are against the stabilizing frame in sequence from bottom to top. When the indicator rod is squeezed, the color of the indicator rod surface gradually darkens.

[0005] A preferred technical solution is that the upper end of the pressing frame is close to the stabilizing frame and is supported by two springs. When the pressing frame swings toward the stabilizing frame, the springs are squeezed and a soft connection cannot be formed between the pressing frame and the stabilizing frame. Two positioning rods are respectively arranged at the corresponding positions of the stable frame and the two springs, and the positioning rods include an engraved telescopic rod and a fixed tube. The engraved telescopic rod is sleeved outside the fixed tube, and the engraved telescopic rod is fixed to the surface of the stable frame. The spring extends to the inside of the fixed tube to abut against it. When the pressing frame is swung toward the stable frame, the pressing frame applies force to the spring and pushes the fixed tube toward the dam body through the spring. The end of the fixed tube away from the stable frame is a pointed cone structure.

[0006] A preferred technical solution is that a handle is symmetrically arranged on the upper end of the pressing frame, and a support rod is fixed on the upper end of the stabilizing frame, and a snap-fitting rod is movably installed on the support rod. When the pressing frame is swung toward the stabilizing frame and squeezed until the surface color of all indicator rods is deepened, the snap-fitting rod swings toward the handle and snaps onto the outside of the handle to fix it.

[0007] A preferred technical solution is that the lower end of the buckle rod is provided with an inwardly concave step edge near the connection end with the support rod, and the stabilizing frame is provided with a support plate at the corresponding position of the step edge. When the buckle rod is buckled on the handle, the support plate abuts against the lower end surface of the buckle rod, and the buckle rod is inclined toward the handle; The buckle rod is movably mounted on the support rod via a torsion shaft, and the force direction of the torsion shaft is the direction in which the buckle rod swings toward the handle.

[0008] A preferred technical solution, all the indicating rods include a fixed column, a rubber contact, and a mechanochromic plate, the end of the fixed column is provided with a movable groove, and the rubber contact is movably installed in the movable groove, and an extrusion rod is provided at one end of the rubber contact facing the movable groove, the extrusion rod is embedded in the movable groove and abuts against the mechanochromic plate arranged in the fixed column, and a gap for the rubber contact to move is provided between the adjacent ends of the rubber contact and the movable groove, and when the rubber contact is squeezed, it moves inward, and squeezes the mechanochromic plate through the extrusion rod, so that the mechanochromic plate changes color as it is subjected to force; A force-applying groove is provided at the corresponding position of the force-induced color-changing plate and the end of the extrusion rod. The width of the force-applying groove is smaller than the outer diameter of the extrusion rod. The end of the extrusion rod is a conical structure. An inwardly concave force-bearing groove is provided at the corresponding position of the force-applying groove and the middle part of the end of the extrusion rod. When the extrusion rod abuts against the force-applying groove, the conical structure at the end of the extrusion rod first abuts against the force-bearing groove.

[0009] A detection method of a dam strength detector for a water conservancy project, applied to the detection method of a dam strength detector for a water conservancy project, the detection method comprises the following specific steps: S1: Install the detection device on the pressing frame, provide a fixed support platform for the detection device through the pressing frame, set the dam strength detector close to the dam body, and swing the fixed frame and the detection device to the dam body through the motor 1 to form a stable support; S2: Grip the handle tightly and push the pressing frame toward the stabilizing frame, using the spring to squeeze the positioning rod and the stabilizing frame until the positioning rod abuts against the dam body; S3: After the positioning rod is against the dam body, observe whether all indicator rods gradually change their surface color during continuous squeezing, and squeeze the stabilizing frame until the surface color of all indicator rods darkens; S4: While continuously pressing the handle, start the detection device to sample the dam body, regard the opening of the pressing frame and the stabilizing frame as a rectangular range, divide the rectangular range into nine area units, detect the strength of the dam body surface corresponding to all area units respectively, and record the strength detected in all unit areas.

[0010] Compared with the prior art, this technical solution has the following advantages: The detection equipment in the prior art does not have a fixed fixing mechanism, which leads to deviation in the direction of force application. The pressing frame of the present invention is connected to the stabilizing frame by a hinge and is tightly pressed against the dam body under the drive of a motor, forming a relatively stable detection platform, which effectively reduces the deviation in the direction of force application. The background technology also points out that each detection in the prior art requires manual measurement, which is too inconvenient. The detection device of the present invention realizes automatic movement and adjustment through motor drive, which greatly improves the convenience and efficiency of detection.

[0011] In actual applications, the working methods of the snap rod and the indicator rod are closely linked. When inspectors use the tester to test the strength of the dam body, they will first press the pressing frame and the stabilizing frame against the dam body and fix them together through the snap rod. In this process, the indicator rod will be in close contact with the dam body and change color when under pressure. Inspectors can judge whether the force is appropriate by observing the color change of the indicator rod, and adjust the position and direction of force of the detection device accordingly. By providing intuitive visual feedback, it shows that the indicator rod has been subjected to sufficient pressure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] like Figures 1 to 8 As shown, the present invention proposes a dam strength detector for water conservancy projects, including a fixed frame 1, a detection device 2, and a motor 3. The detection device 2 is installed on the fixed frame 1. The fixed frame 1 includes a pressing frame 11 and a stabilizing frame 12. The lower end of the pressing frame 11 is swingably connected to the stabilizing frame 12 through a hinge. The stabilizing frame 12 is installed on the output shaft of the motor 3, so that the pressing frame 11 and the stabilizing frame 12 are pressed against the dam body by rotating the stabilizing frame 12. The detection device 2 includes a strength detector 21, a screw slide 22, and a motor 23. The screw slide 22 is arranged in a rectangular array, and each screw slide 22 is connected to the output shaft of a motor 23. A screw slider 221 is installed on the screw slide 22, and the screw slider 221 forms a screw transmission connection with the screw slide 22. The side of the strength detector 21 is connected to the screw sliders 221 on all sides through four telescopic rods 211. The corresponding motor 2 23 is driven to allow the screw guide rail 22 to drive the strength detector 21 to move or adjust in the corresponding direction.

[0023] The middle parts of the pressing frame 11 and the stabilizing frame 12 are both provided with openings for the detection device 2 to detect the dam body. The edge of the pressing frame 11 facing the stabilizing frame 12 is provided with an outwardly protruding indicator rod 113. The indicator rods 113 are arranged equidistantly along the edge of the pressing frame 11, and the length of the indicator rods 113 gradually shortens from top to bottom. When the pressing frame 11 is pushed toward the stabilizing frame 12, all the indicator rods 113 are against the stabilizing frame 12 from bottom to top in sequence. When the indicator rods 113 are squeezed, the surface color of the indicator rods 113 gradually deepens. The indicator rods 113 are made of mechanochromic material and can produce a certain color change when squeezed by force. In addition, the upper end of the pressing frame 11 close to the stabilizing frame 12 is supported against the stabilizing frame 12 by two springs 114. When the pressing frame 11 swings toward the stabilizing frame 12, the springs 114 are squeezed and cannot form a soft connection between the pressing frame 11 and the stabilizing frame 12. Two positioning rods 124 are respectively provided at the corresponding positions of the stabilizing frame 12 and the two springs 114. The positioning rods 124 include a stamped telescopic rod 1241 and a fixing tube 124. 42, the engraved telescopic rod 1241 is sleeved outside the fixed tube 1242, and the engraved telescopic rod 1241 is fixed on the surface of the stable frame 12, and the spring 114 extends to the inside of the fixed tube 1242 to resist it. When the pressing frame 11 is squeezed and swung toward the stable frame 12, the pressing frame 11 applies force to the spring 114, and the fixed tube 1242 is pushed toward the dam body through the spring 114. The end of the fixed tube 1242 away from the stable frame 12 is a pointed cone structure; Based on the above content, the method of using the pressing frame 11 is as follows: Installation and preparation: First, connect the pressing frame 11 with the stabilizing frame 12 through hinges, and ensure that the fixing frame is installed on the output shaft of the motor 1 3 as a whole. At the same time, install the detection device 2 on the fixing frame 1, especially the strength detector 21 is connected to the screw slider 221 on the screw slide rail 22 through the telescopic rod 211; Positioning and pressing: Start the motor 3, and drive the stabilizing frame 12 to the surface of the dam body through the rotation of its output shaft, and then push the pressing frame 11 toward the stabilizing frame 12 manually or mechanically until the two are tightly pressed against the dam body. At this time, the indicator rod 113 on the pressing frame 11 will contact the stabilizing frame 12 and change color, indicating that a certain amount of pressure has been applied; Detection and adjustment: After the pressing frame 11 and the stabilizing frame 12 are stably pressed against the dam body, the motor 23 is started to drive the screw guide rail 22 to drive the strength detector 21 to move within the predetermined detection area to perform multi-point strength detection. During the detection process, the force application situation can be preliminarily judged by observing the color change of the indicator rod 113 to ensure the accuracy of the detection; It is mentioned in the background technology that the detection equipment in the prior art does not have a fixed fixing mechanism, resulting in a deviation in the force direction, while the pressing frame 11 of the present invention is connected to the stabilizing frame 12 by a hinge, and is tightly pressed against the dam body under the drive of the motor, forming a relatively stable detection platform, which effectively reduces the deviation in the force direction. The background technology also points out that each detection in the prior art requires manual measurement, which is too inconvenient, while the detection device 2 of the present invention realizes automatic movement and adjustment through motor drive, which greatly improves the convenience and efficiency of detection; The method of using the stabilizing frame 12 is closely connected with the pressing frame 11, which is mainly reflected in the following aspects: Installation and connection: As a part of the fixed frame, the stable frame 12 first needs to be installed on the output shaft of the motor 3 and connected to the pressing frame 11 through a hinge. After ensuring that the connection is stable, subsequent operations can be performed.

[0024] Positioning and support: Driven by the motor 3, the stabilizing frame 12 is first driven to the surface of the dam body to play a role in preliminary positioning and support. Subsequently, the pressing frame 11 is pressed tightly against it under manual or mechanical push to form a stable detection platform; Auxiliary detection: The positioning rod 124 and other structures on the stable frame 12 also play an auxiliary detection role. For example, the positioning rod 124 can cooperate with the corresponding structure on the pressing frame 11 to further ensure the stability and accuracy of the detection device 2 during the detection process; Similar to the pressing frame 11, the use of the stabilizing frame 12 is also intended to create a relatively stable detection environment. Through motor drive and structural design, it ensures that the detection device 2 can maintain a stable force direction and detection position during the detection process, thereby improving the accuracy of the detection. The problem of human measurement error mentioned in the background technology has been effectively alleviated in the present invention. The close cooperation between the stabilizing frame 12 and the pressing frame 11 and the automated operation of the detection device reduce the influence of human factors on the detection results.

[0025] Furthermore, a handle 112 is symmetrically provided on the upper end of the pressing frame 11, and a support rod 121 is fixed to the upper end of the stabilizing frame 12, and a buckling rod 122 is movably installed on the support rod 121. When the pressing frame 11 is swung toward the stabilizing frame 12 and squeezed until the surface color of all the indicator rods 113 is darkened, the buckling rod 122 swings toward the handle 112 and buckles outside the handle 112 to fix it.

[0026] Furthermore, the lower end of the buckle rod 122 is provided with an inwardly recessed step edge near the connection end with the support rod 121, and the stabilizing frame 12 is provided with a support plate 123 at a position corresponding to the step edge. When the buckle rod 122 is buckled on the handle 112, the support plate 123 abuts against the lower end surface of the buckle rod 122, and the buckle rod 122 is inclined toward the handle 112; The buckle rod 122 is movably mounted on the support rod 121 through a torsion shaft 1221, and the force direction of the torsion shaft 1221 is the direction in which the buckle rod 122 swings toward the handle 112; All the indicating rods 113 include a fixed column 131, a rubber contact 132, and a mechanochromic plate 133. The end of the fixed column 131 is provided with a movable groove 1311, and the rubber contact 132 is movably installed in the movable groove 1311, and an extrusion rod 1321 is provided at one end of the rubber contact 132 facing the movable groove 1311. The extrusion rod 1321 is embedded in the movable groove 1311 and abuts against the mechanochromic plate 133 provided in the fixed column 131. A gap for the rubber contact 132 to move is provided between the adjacent ends of the rubber contact 132 and the movable groove 1311. When the rubber contact 132 is squeezed, it moves inwards and squeezes the mechanochromic plate 133 through the extrusion rod 1321, so that the mechanochromic plate 133 changes color as it is subjected to force. A force-applying groove 1331 is provided at the corresponding position of the mechanochromic plate 133 and the end of the extrusion rod 1321. The width of the force-applying groove 1331 is smaller than the outer diameter of the extrusion rod 1321. The end of the extrusion rod 1321 is a conical structure. A force-bearing groove 1332 concave inwardly is provided at the corresponding position of the force-applying groove 1331 and the middle part of the end of the extrusion rod 1321. When the extrusion rod 1321 abuts against the force-applying groove 1331, the conical structure at the end of the extrusion rod 1321 abuts against the force-bearing groove 1332 first. In the dam strength detector for water conservancy projects, the buckle rod 122 and the indicator rod 113, although each has a unique function and structure, in actual use, they work together to ensure the stability of the detector and the accuracy of the detection; First, the buckle rod 122 cooperates with the support plate 123 on the stable frame 12 through the step edge at its lower end. When the buckle rod 122 is buckled on the handle 112, the support plate 123 provides support for the buckle rod 122 and tilts it toward the handle 112. This design not only enhances the connection stability between the pressing frame 11 and the stable frame 12, but also ensures that the detection device 2 can maintain a stable force direction during the detection process. At the same time, as an important component of the pressing frame 11, the structure and working principle of the indicator rod 113 are also worth mentioning. Each indicator rod 113 is composed of a fixed column 131, a rubber contact 132 and a mechanochromic plate 133. When the pressing frame 11 swings toward the stable frame 12 and presses against the dam body, the rubber contact 132 on the indicator rod 113 will first contact the dam body and be squeezed. This squeezing will cause the rubber contact 132 to move inward and apply pressure to the mechanochromic plate 133 through the squeezing rod 1321. As the pressure increases, the mechanochromic plate 133 will change color, thereby providing intuitive visual feedback, indicating that the indicator rod 113 has been subjected to sufficient pressure; In practical applications, the working modes of the buckle rod 122 and the indicator rod 113 are closely connected. When the inspectors use the detector to test the strength of the dam body, they first press the pressing frame 11 and the stabilizing frame 12 against the dam body and fix them together through the buckle rod 122. During this process, the indicator rod 113 will be in close contact with the dam body and change color when under pressure. The inspectors can judge whether the force is appropriate by observing the color change of the indicator rod 113, and adjust the position and force direction of the detection device 2 accordingly. In summary, the buckle rod 122 and the indicator rod 113 play their own unique roles in the dam strength tester for water conservancy projects, and work together to ensure the accuracy and stability of the test. The buckle rod 122 provides a stable connection and support, while the indicator rod 113 provides intuitive visual feedback to help testers better control the direction and strength of the force. Based on the above statements, the present invention also provides a detection method of a dam strength detector for a water conservancy project, which is applied to the detection method of a dam strength detector for a water conservancy project, and the detection method includes the following specific steps: S1: Installation and pre-positioning The detection device 2 is securely mounted on the pressing frame 11 to ensure that the detection device 2 has a stable supporting platform; Move the entire dam strength tester to a position close to the dam body; Start the motor 1 3 to drive the fixing frame 1 and the detection device 2 to swing until they are tightly against the dam body and form a stable supporting state; S2: Press and Position Grip the handle 112 and push the pressing frame 11 towards the stabilizing frame 12 manually or mechanically; During the pushing process, the spring 114 will squeeze the positioning rod 124 and the stabilizing frame 12 until the tip of the positioning rod 124 is tightly against the surface of the dam body; S3: Observe and adjust After the positioning rod 124 abuts against the dam body, carefully observe whether all the indicator rods 113 gradually change their surface colors under continuous squeezing; Continue squeezing the stabilizing frame 12 until the surface colors of all indicator rods 113 are significantly darker, which indicates that sufficient pressure has been applied to the dam body; S4: Detection and Recording While continuously pressing the handle 112, the detection device 2 is activated to perform sampling detection on the dam body; The opening between the pressing frame 11 and the stabilizing frame 12 is regarded as a rectangular detection range, and the rectangular range is equally divided into nine small area units; The strength of the dam surface corresponding to all regional units is detected separately, and the detection strength results of each unit are recorded.

[0027] Based on the above content, it can be seen that this detection method is a step in the dam strength detection, and its purpose is to more accurately detect the strength of different areas of the dam. This method of dividing the rectangular range into nine small areas for detection has several significant advantages. First, by subdividing the detection area, a more accurate measurement of the dam strength can be achieved, thereby improving the accuracy of the detection. Secondly, this method makes the detection process more systematic, and each small area can be regarded as an independent detection unit, which helps to better grasp the distribution of the dam strength. Finally, by comparing the strength data of different small areas, it is easier to find the weak links in the dam strength, providing targeted guidance for subsequent maintenance and reinforcement work; In terms of working principle, this method makes full use of the relative movement between the pressing frame and the stabilizing frame, as well as the color change of the indicator rod when it is under pressure. When the detection device is pressed against the dam body, the indicator rod can be brought into close contact with the dam body by holding the handle tightly and pushing the pressing frame toward the stabilizing frame. As the pressure increases, the indicator rod will change color, thereby providing intuitive visual feedback. By dividing the rectangular range into nine small areas and observing the color change of the indicator rod corresponding to each small area, a comprehensive and accurate detection of the dam body strength can be achieved.

[0028] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
