Description

Technical Field

[0001] This utility model relates to the field of crack detection technology, and in particular to an auxiliary tool for crack detection in water conservancy dams. Background Technology

[0002] Crack detection technology is a technical system that uses visual observation, non-destructive testing (such as acoustic waves and electromagnetic waves), and sensor monitoring, combined with data processing and algorithm analysis, to identify and locate cracks on and inside structural surfaces, and quantify their length, width, depth, and other parameters. In the context of hydraulic dams, this technology needs to be adapted to the dam's concrete material and complex environment (such as underwater or high humidity). Its core function is to provide accurate crack data support for dam safety assessment and maintenance, serving as a key technological foundation for ensuring the stable operation of dams.

[0003] Based on the core needs of crack detection technology in on-site data acquisition and manual interpretation, the core design of the auxiliary tool for crack detection in water conservancy dams is to help staff work efficiently. For example, portable devices pre-loaded with electronic drawings of the dam and coordinates of the detection points can replace traditional paper documents, allowing staff to quickly mark crack locations and enter preliminary measurement data such as lengths on the device, significantly reducing errors from manual recording. When further detection is needed, staff can use this tool to simultaneously retrieve historical detection data for the corresponding area, helping to determine the optimal detection angle and position of the acoustic probe, providing a reference for subsequent accurate detection, and making on-site operations more orderly and efficient.

[0004] However, in existing technologies, the plugs and detectors of some hydraulic dam crack detection equipment rely on a single interference fit or foundation plug-in method for fixation. Under the frequent equipment movement, operational vibration, and collisions at the dam inspection site, this type of connection structure is prone to loosening or even plug detachment. This may not only cause interruption or signal distortion in the transmission of crack data collected by the probe, but also affect the efficiency of the inspection operation due to connection failure, and even bring the risk of equipment damage.

[0005] Therefore, an auxiliary tool for detecting cracks in water conservancy dams is proposed to address the above-mentioned problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an auxiliary tool for detecting cracks in water conservancy dams. It aims to improve the problem that the connection structure between the plug and the detector of some existing water conservancy dam crack detection equipment is prone to loosening or even plug detachment under conditions such as frequent equipment movement, operational vibration, and collisions at the dam detection site.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An auxiliary tool for detecting cracks in water conservancy dams includes a detector. A connector is fixedly connected to the top of the detector. A plug is detachably connected to the outside of the connector. A clamping component is slidably connected to the outside of the plug. A pressure plate is slidably connected to the bottom of the clamping component. Multiple round-headed pins are fixedly connected to the bottom of the pressure plate.

[0014] One end of the spring is fixedly connected to one side of the inner plate, and the other end of the spring is fixedly connected to one side of the inner wall of the protective shell.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0018] A data cable is fixedly connected to the top of the plug, and a probe is fixedly connected to the other end of the data cable.

[0019] As a further description of the above technical solution:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 4This utility model provides an embodiment of an auxiliary tool for detecting cracks in water conservancy dams, comprising a detector 1, a connector fixedly connected to the top of the detector 1 for connecting a plug 2 to achieve data transmission; a plug 2 is detachably connected to the outside of the connector, the plug 2 for connecting the connector and a data cable 14 to form a data transmission path; a clamping component is slidably connected to the outside of the plug 2, the clamping component, through the continuous force of a spring 6, keeps the protective shell 3 in a downward state, achieving the dual effects of enhanced locking and sealing; the clamping component includes a protective shell 3 sliding outside the plug 2, the protective shell 3, through sliding cooperation with the plug 2, and in conjunction with the force of the spring 6, ensures the stable connection of each component, while providing an installation base for the rubber ring 4 and forming a protective barrier.

[0034] A rubber ring 4 is fixedly connected to the bottom of the protective shell 3. The rubber ring 4 fits against the top of the detector 1 to enhance the sealing and is part of the double sealing structure. The bottom of the rubber ring 4 is in close contact with the top of the detector 1. An inner plate 5 is fixedly connected to the outside of the plug 2. The inner plate 5 provides a fixed support point for the spring 6. A spring 6 is provided at the bottom of the inner plate 5. The spring 6 provides power to keep the protective shell 3 in a downward state by continuously generating force, which strengthens the locking and sealing. One end of the spring 6 is fixedly connected to one side of the inner plate 5, and the other end of the spring 6 is fixedly connected to one side of the inner wall of the protective shell 3. A pressure plate 7 is slidably connected to the bottom of the pressing component. The pressure plate 7 fits tightly against the locking block 9 to enhance the locking effect. Its bottom contacts the inner wall of the retaining ring 13 to enhance stability.

[0035] The top of the pressure plate 7 is slidably connected to the bottom of the protective shell 3. Multiple round-headed pins 8 are fixedly connected to the bottom of the pressure plate 7. After the round-headed pins 8 are inserted into the sockets 10, they form a locking structure with the rubber plugs 11. This is a component of multiple mechanical fixation, which can prevent the plug 2 from loosening or falling off. Two locking blocks 9 are fixedly connected to the bottom of the plug 2. The locking blocks 9 engage with the locking ring 13 to form a further mechanical lock, which strengthens the connection between the plug 2 and the connector. Multiple sockets 10 are opened on the top of the locking blocks 9 to engage with the round-headed pins 8. The sockets 10 provide insertion space for the round-headed pins 8 and are the basis for forming the locking structure. The inner wall of the sockets 10 is fixedly connected to the plugs 11 to engage with the round-headed pins 8. The plugs 11 are made of rubber and the opening diameter is smaller than the diameter of the round head of the round head of the pin 8. When the round head is inserted, it will be stretched open. After being fully inserted, it will elastically contract and wrap around the round head to achieve locking.

[0036] The opening of the insertion platform 11 is connected to the insertion hole 10. The insertion platform 11 is a rubber insertion platform 11. The top of the detector 1 is fixedly connected to a retaining ring 13 that engages with the retaining block 9. The retaining ring 13 provides a retaining space for the retaining block 9 and forms a mechanical fixation by cooperating with the retaining block 9. Its inner wall contacts the rubber pad 12 to form a preliminary seal. The bottom of the pressure plate 7 rotates on the top of the retaining block 9, and the bottom of the pressure plate 7 is in close contact with the inner wall of the retaining ring 13. The bottom of the retaining block 9 is fixedly connected to a rubber pad 12. The rubber pad 12 is in close contact with the inner wall of the retaining ring 13 to form a preliminary seal, which is a component of the double sealing structure. The outside of the rubber pad 12 is slidably connected to the inner wall of the retaining ring 13. The top of the plug 2 is fixedly connected to a data cable 14. The data cable 14 is used to transmit the crack data collected by the probe 15 to the detector 1. The other end of the data cable 14 is fixedly connected to the probe 15. The probe 15 is used to collect crack data of the dam.

[0037] Working principle: When installing the data cable 14 and probe 15, first align the plug 2 with the connector on the top of the detector 1, and pull the protective shell 3 upward to expose the locking block 9. At this time, the spring 6 between the inner plate 5 and the protective shell 3 will generate a rebound force due to stretching. Then, insert the plug 2 into the connector, so that the locking block 9 is inserted into the groove at the top of the retaining ring 13. Rotate the plug 2 to make the locking block 9 slide into the retaining groove of the retaining ring 13 to complete the engagement. The bottom rubber pad 12 is in close contact with the inner wall of the retaining ring 13 to form a preliminary seal.

[0038] After the protective shell 3 is released, the spring 6 contracts, causing the protective shell 3 to descend. The bottom rubber ring 4 fits against the top of the detector 1 to enhance the seal. Rotate the protective shell 3 until the pressure plate 7 aligns with the locking block 9. The round-headed insertion post 8 moves down with the protective shell 3 and inserts into the insertion hole 10. Because the insertion platform 11 is made of rubber and its opening diameter is smaller than the diameter of the round head of the insertion post 8, the round head will open the opening of the insertion platform 11. After it is fully inserted, the insertion platform 11 elastically contracts to wrap around the round head and lock it in place.

[0039] During testing, the crack data collected by probe 15 is transmitted to detector 1 via data cable 14. The sliding fit between protective shell 3 and plug 2, and the continuous force of spring 6, ensure stable connection of each component. The double seal of rubber pad 12 and rubber ring 4 can resist water vapor and dust at the dam site, ensuring stable operation of the equipment in complex environments.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
