Description

Technical Field

[0001] The invention relates to the technical field of dam body detection, in particular to a strength detection device for a dam body of a water conservancy project. Background Art

[0002] The safety of the dam of a water conservancy project is extremely important, and its strength is directly related to the stability of the entire water conservancy project and the safety of life and property of people in the surrounding areas. With the continuous expansion of the scale of water conservancy project construction and the increase in operating time, dam strength testing has become a key link in ensuring the safety of water conservancy facilities.

[0003] In the prior art, a Chinese patent with publication number CN221038322U discloses a dam strength detection device, including a protective tube, in which a rebounding hammer is inserted; a rotating assembly is connected to the protective tube, and a cleaning assembly is connected to the driving end of the rotating assembly; a fixed assembly that is the same as the fixed rebounding hammer is connected to the protective tube; a placement assembly is provided on the protective tube, and a video recording assembly is installed on the placement assembly. This solution can not only protect the rebounding hammer during use, but also set up a variety of tools. The use of a variety of tools can facilitate the user to clean the impurities on the dam body during the detection process, thereby facilitating the detection work of the user and indirectly improving the work efficiency of the user. At the same time, the user can use a camera to record the data on the rebounding hammer, which further facilitates the work of the staff and indirectly improves the work efficiency of the staff.

[0004] The dam strength detection device provided by the above patent uses the rebound method to detect the strength of the dam concrete. The rebound method is relatively simple to operate, but it can only detect the hardness of the dam surface to infer the strength. Since the dam surface is affected by factors such as weathering and erosion, its detection results often cannot accurately reflect the true strength of the dam inside. For dams with internal damage or uneven quality, the detection accuracy is poor.

[0005] In addition to the rebound method, the common dam strength testing methods include the core drilling method and the ultrasonic testing method. Although the core drilling method can directly obtain the core sample of the dam body for strength testing, this method will cause certain damage to the dam body and leave holes on the dam body, affecting the structural integrity of the dam body. In addition, the detection cost is high and the efficiency is low, and it is not possible to conduct large-scale and frequent detection of the dam body. Although the ultrasonic detection method is accurate, it requires a large number of detection points to be tested, which is a large workload. In addition, the dam body is often equipped with deep internal channels, which often have the problem of hypoxia, so it is not convenient for staff to enter. The existing dam body detection methods all require manual operation, which makes it inconvenient for the existing dam body detection methods to detect its internal channels, which is not conducive to a comprehensive detection of the dam body. In summary, the market now needs a device that can assist staff to conduct a comprehensive detection of the dam body concrete strength efficiently and accurately. Summary of the invention

[0054] Working principle: When in use, fully charge the crawler vehicle 1 to ensure that the crawler vehicle 1 has sufficient power, then design the detection route according to the structure of the dam body, and input the route into the crawler vehicle 1. The position of the crawler vehicle 1 can be understood in real time through the GPS positioning module inside the crawler vehicle 1, and then the staff can control the movement of the crawler vehicle 1 through the terminal, so that the crawler vehicle 1 can move along the set route. When the crawler vehicle 1 moves to the detection point, the crawler vehicle 1 stops operating, and the cooperation between the crawler vehicle 1 and the swing arm 51 makes the detection component 6 align with the position of the detection point, and adjusts the angle of the detection component 6 to align with the detection point through the detection adjustment motor 52, and then drives the ultrasonic detection probe 64 and the rebound detection probe 63 to press against the concrete of the dam body through the electric push rod 62, and then judges whether the strength of the dam body is normal through the data detected by the ultrasonic detection probe 64 and the rebound detection probe 63. After the detection of the detection point is completed, the crawler vehicle 1 will continue to move forward according to the set route and continue to detect the next detection point. When the internal passage of the dam needs to be inspected, the crawler 1 can be placed in the internal passage of the dam, and the crawler 1 can be controlled by the terminal to move and inspect. The cooperation of the visual camera 3 and the fill light 4 enables the staff to observe the road conditions in real time, so as to handle the abnormality in time.

[0055] In summary, compared with the prior art, the present application uses the crawler vehicle 1 to carry various detection components to detect the dam body, and the staff only needs to remotely control the crawler vehicle 1 to move along the designed route. After the crawler vehicle 1 moves to the detection point, it will control the detection component 6 to detect the concrete strength of the detection point, and then continue to move to the next point for detection, so that the dam body can be detected efficiently and quickly. At the same time, the detection component 6 is integrated with a rebound test probe and an ultrasonic detection probe 64. The dam body can be detected with high precision through the rebound tester 61 and the ultrasonic tester 61, and the crawler vehicle 1 can also enter the pipeline inside the dam body to detect the inside of the dam body, which can assist the staff to detect the dam body in an all-round way.

[0056] Example 3

[0057] This embodiment provides a method for a video acquisition unit to cooperate with a detection component 6 to acquire images of a dam body and detect the concrete strength. The specific steps of the method are as follows:

[0058] S100. Set concrete strength test points on the dam body. The positions and arrival paths of the test points can be pre-stored in the control system of the crawler vehicle 1. The setting of concrete strength test points should be representative and can truly reflect the quality status of the dam body concrete. The influence of factors such as the concrete pouring position, construction technology, and raw material changes should be considered. For example, for a large-volume concrete dam body, a test point should be set for each pouring position. Generally speaking, for smaller pouring positions (such as an area of ​​less than 100 square meters), no less than 3 test points can be set; for larger pouring positions (an area greater than 100 square meters), the number of test points should be increased in a certain proportion according to the size of the position. Normally, at least one test point is added for every additional 100 square meters.

[0059] The detection points should be evenly distributed in the casting position to avoid being concentrated in a certain area. For example, for rectangular casting positions, detection points can be set at the four corners and the center of the position, and for circular positions, they can be set at the circumference and the center of the circle. At the construction joint, detection points should be set on both sides of the joint. For higher dam bodies, detection points should be set in layers along the height direction of concrete pouring. Generally, a layer of detection points can be set every 3-5 meters, and the positions of the detection points of each layer should also be evenly distributed on the plane according to the above principles. In this way, the changes in the strength of concrete at different heights can be monitored, because with the increase in the pouring height, the construction conditions of concrete (such as the drop of concrete, the difficulty of vibration, etc.) may change, thereby affecting the strength. If the raw materials (such as cement varieties, sources of sand and gravel, etc.) change during the pouring of dam concrete, detection points should be added at the concrete junction before and after the change. This makes it easy to timely discover the potential impact of raw material changes on concrete strength and ensure the stability of dam quality.

[0060] S200, the crawler vehicle 1 moves to the vicinity of the concrete strength detection point, and through the cooperation of the swing component 5 and the detection component 6, the video acquisition and image processing of the dam body detection point position are performed.

[0061] S300: Identify the boundary of the slope surface on the acquired image, and determine two feature point sets of the upper and lower edges of the slope surface.

[0062] S400. Establish a two-dimensional rectangular coordinate system in the image. The origin can be the lower left corner of the image or other convenient position for calculation. The x-axis is horizontal to the right and the y-axis is vertical to the top. Use image analysis software to obtain the coordinate values ​​of the feature points of the upper and lower edges of the slope in the coordinate system. The coordinates of the two feature points at the bottom edge of the slope are (x1, y1) and (x2, y2), and the coordinates of the two feature points corresponding to the top edge are (x3, y3) and (x4, y4).

[0063] S500, calculate the slope of the upper and lower edge lines of the slope, the slope of the bottom edge line Top edge line slope Then calculate the slope angle θ (unit: radian), the calculation formula is:

[0064] S600, feeding back the slope inclination angle θ to the inclination driving unit, which cooperates with the swing component 5 to drive the detection component 6, so that the detection component 6 rotates until the ultrasonic detection probe 64 and the rebound detection probe 63 are perpendicular to the dam slope at the detection point.

[0065] S700, the electric push rod 62 drives the ultrasonic detection probe 64 and the rebound detection probe 63 to the concrete strength detection point; the rebound detection probe 6 performs rebound measurement on the dam concrete surface, and the measured rebound representative value is R. The ultrasonic transmitting probe in the ultrasonic detection probe 64 transmits ultrasonic waves, and the ultrasonic receiving probe receives ultrasonic waves, and the wave velocity V is calculated:

[0066]

[0067] Wherein, d is the distance between the ultrasonic transmitting probe and the ultrasonic receiving probe, and t is the time from when the ultrasonic transmitting probe transmits the ultrasonic wave to when the ultrasonic receiving probe receives the ultrasonic wave;

[0068] Then calculate f0 using the rebound representative value R and wave speed V as follows:

[0069] f0=0.0286ν 1.999 R 1.155

[0070] f0 is the converted value of concrete compressive strength at the testing point.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
