Description

Technical Field

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

[0002] Dams are used to intercept water flows and regulate upstream water levels. Therefore, damage to dams can cause significant damage to the surrounding ecological environment. Regular dam strength testing is key to ensuring the safe and stable operation of water conservancy facilities. Rebound and ultrasonic methods are non-destructive and can quickly acquire strength data over a large area.

[0003] After searching, the invention patent with authorization announcement number CN118464597B discloses a strength testing device for a water conservancy project dam body. Through the mutual cooperation of the adjustment mechanism and the torque adjustment mechanism, the pressing component can adjust the force application position of the pressing component as the second telescopic rod is extended and retracted before applying pressure to the rebound hammer, so that the left and right force arms can be in the same state, ensuring the stability of the rebound hammer when pressing down and improving the accuracy of the rebound hammer during measurement. Although the above-mentioned strength testing device can be used for dam body strength testing, in the process of actually testing the dam body concrete strength using the rebound method, since there are usually multiple evenly distributed measuring points in a measuring area, it is necessary to manually adjust the device multiple times during the single measuring area detection process to achieve the detection of multiple measuring points. The operation process is extremely cumbersome, too labor-intensive and has a great impact on the detection efficiency. In addition, due to the obstruction of the positioning arc plate, the relevant testing personnel cannot accurately judge whether the rebound hammer's impact rod has moved to the corresponding measuring point during the adjustment process, which further increases the difficulty of adjustment.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a strength detection device for a water conservancy project dam body to overcome the above technical problems existing in the existing related art.

[0006] The technical solution of the present invention is achieved as follows:

[0016] Furthermore, the rebound detection mechanism includes an inverted L-shaped movable seat that is slidably arranged on the inner side of the guide groove and slidably sleeved on the outer side of the second guide rod. A reciprocating screw is provided through the bottom of the inverted L-shaped movable seat. The reciprocating screw is rotatably connected to the inverted L-shaped movable seat through a bearing. The top plate of the inverted L-shaped movable seat is fixedly provided with a driving member that is transmission-connected to the reciprocating screw.

[0017] Furthermore, a lifting seat is provided in the transmission sleeve on the outer side of the reciprocating screw, a rack meshing with the gear is fixedly provided on the right side of the top of the lifting seat, a convex column is rotatably nested on the front of the lifting seat through a bearing, a rebound tester is fixedly provided on the bottom of the lifting seat, and a third guide rod fixedly connected to the convex column is slidingly penetrated on the left side of the top plate of the inverted L-shaped movable seat, and a receiving groove for accommodating the rack is provided on the right side of the front of the inverted L-shaped movable seat, and the rear parts of the two annular partitions are both located on the inner side of the receiving groove.

[0020] 2. The present invention enhances the stability of the equipment and optimizes its operational convenience. The reinforcement components of the measuring point positioning mechanism allow the equipment to be fixed by stepping on or holding it, preventing it from shaking during testing. The sliding cooperation between the inverted L-shaped moving seat and the second guide rod and guide groove in the rebound testing mechanism, as well as the position limiting of the protruding column by the third guide rod, ensure the stability of the rebound tester during the lifting and movement process, and avoid detection deviations caused by equipment displacement. In addition, the second handle facilitates manual pulling of the overall movement of the measuring point switching mechanism, and in conjunction with the automatic switching mechanism, the detection path can be flexibly controlled. The driving member drives the reciprocating screw to realize the automatic lifting and lowering of the rebound tester, reducing manual operation steps, reducing labor intensity, and making the detection process simpler.

[0021] In summary, the present invention overcomes the problems of existing equipment requiring multiple manual adjustments, non-intuitive measurement point positioning, and low detection efficiency. Through the automated design of the mechanical structure, continuous and accurate detection of multiple measurement points in the measurement area is achieved, while avoiding the obstruction of the positioning structure to the observation of the measurement points, reducing the difficulty of operation, and meeting the efficiency and reliability requirements of the dam strength detection of water conservancy projects.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0038] According to an embodiment of the present invention, a strength detection device for a dam body of a water conservancy project is provided.

[0039] like Figure 1-Figure 5 As shown, the strength detection equipment for the dam body of a water conservancy project according to an embodiment of the present invention includes: a shell component 1, a measuring point positioning mechanism 2 is fixedly provided at the bottom of the shell component 1, a measuring point switching mechanism 3 is slidingly provided at the top of the shell component 1, and a rebound detection mechanism 4 is slidingly provided on the measuring point switching mechanism 3.

[0040] like Figure 2 As shown, the housing assembly 1 includes a square shell 11, with through slots 12 on both sides of the square shell 11, and guide assemblies fixedly provided on both sides of the top of the square shell 11. A plurality of avoidance channels 15 and guide channels 16 are evenly distributed on the front of the square shell 11, and any guide channel 16 is connected to the adjacent avoidance channel 15;

[0041] This technical solution facilitates the protrusion 46 to enter the inner side of the adjacent avoidance channel 15 under the drive of the lifting seat 44. During the detection process, the protrusion 46 continues to move downward along the adjacent avoidance channel 15 under the drive of the lifting seat 44. During the subsequent upward movement of the lifting seat 44, the protrusion 46 is driven to move up along the avoidance channel 15 and reset, and then enter the inner side of the adjacent guide channel 16. At this time, due to the guiding effect of the guide channel 16, the inverted L-shaped moving seat 41 slides to the right along the guide groove 32 and the second guide rod 38, thereby driving the rebound detection mechanism 4 to move to just above the laterally adjacent positioning groove 22;

[0042] Among them, any group of guide components includes a C-shaped side plate 13 and a first guide rod 14. The C-shaped side plate 13 is fixedly arranged on the top side of the square shell 11 and its top is provided with a rough surface for increasing friction with the adjacent traveling wheel 35. The first guide rod 14 is fixedly arranged on the inner side of the C-shaped side plate 13.

[0043] This technical solution facilitates the use of the first guide rod 14 to guide the movement of the U-shaped seat 31, and the setting of the rough surface ensures the friction between the C-shaped side plate 13 and the traveling wheel 35, thereby ensuring that when the traveling wheel 35 rotates, it can accurately drive the rebound detection mechanism 4 to move to the top of the adjacent positioning groove 22 in the same vertical column.

[0044] like Figure 3As shown, the measuring point positioning mechanism 2 includes a bottom plate 21 fixedly arranged at the bottom of the square housing 11, a plurality of evenly arranged positioning grooves 22 are evenly opened on the top of the bottom plate 21, and reinforcement components are fixedly arranged on both sides of the bottom plate 21;

[0045] With the help of the above solution, the measurement area is determined on the surface of the dam body. Then, the device is placed on the top of the measurement area. At this time, the bottom plate 21 attached to the top of the measurement area directly divides the measurement area into multiple evenly distributed measurement points through multiple positioning grooves 22, without the need for manual line drawing.

[0046] In addition, any group of reinforcement components includes two ear plates 23, both ear plates 23 are fixedly connected to the base plate 21, a pedal 24 is rotatably connected between the two ear plates 23 through a pin shaft, and a first handle 25 is fixedly provided on the side of the top of the first handle 25 away from the base plate 21.

[0047] This technical solution is to rotate the two pedals 24 from a vertical state to a horizontal whole with the pin as the center. At this time, the two pedals 24 are in contact with the surface of the dam body, and then the device can be reinforced by stepping on the pedals 24 or holding the first handle 25.

[0048] like Figure 4 As shown, the measuring point switching mechanism 3 includes a U-shaped seat 31 slidably sleeved on the outside of the two first guide rods 14, a guide groove 32 is provided at the bottom of the U-shaped seat 31, and an avoidance groove 33 is provided at the front end of the inner side of the U-shaped seat 31. A rotating shaft 34 is rotatably nested on the inner side of the U-shaped seat 31 through a bearing, and both ends of the outer side of the rotating shaft 34 are provided with traveling wheels 35 connected by an overrunning clutch. A limiting groove 36 is provided at the top of the rotating shaft 34, and a limiting slider is slidably provided inside the limiting groove 36. A gear 37 fixedly connected to the limiting slider is slidably sleeved on the outer side of the rotating shaft 34, and an annular partition is rotatably nested on both sides of the gear 37 through bearings. A second guide rod 38 is fixedly provided at the rear end of the inner side of the U-shaped seat 31, and a second handle 39 is fixedly provided at the rear end of the second guide rod 38.

[0049] The present technical solution is to drive the gear 37 to rotate when the rack 45 moves downward, and the gear 37 drives the rotating shaft 34 to rotate synchronously through the limit slider and the limit slide groove 36. However, since the traveling wheel 35 is connected to the rotating shaft 34 through the overrunning clutch, which is equivalent to a ratchet pawl structure, the traveling wheel 35 does not rotate. During the upward and reset process of the lifting seat 44, the rack 45, which is no longer engaged with the gear 37 due to the downward movement of the lifting seat 44, resumes its engagement with the gear 37. Subsequently, as the lifting seat 44 continues to rise, the rack 45 drives the gear 37 to rotate in the opposite direction. At this time, the rotating shaft 34 drives the traveling wheel 35 to move on the top of the adjacent C-shaped side plate 13. During the movement of the traveling wheel 35, the U-shaped seat 31 is driven to move synchronously along the first guide rod 14 through the rotating shaft 34, thereby driving the rebound detection mechanism 4 to move to just above the adjacent positioning groove 22 in the same vertical column.

[0050] like Figure 5 As shown, the rebound detection mechanism 4 includes an inverted L-shaped movable seat 41 which is slidably arranged on the inner side of the guide groove 32 and slidably sleeved on the outer side of the second guide rod 38. A reciprocating screw 42 is provided at the bottom of the inverted L-shaped movable seat 41, and the reciprocating screw 42 is rotatably connected to the inverted L-shaped movable seat 41 through a bearing. A driving member 43 that is transmission-connected to the reciprocating screw 42 is fixedly provided on the top plate of the inverted L-shaped movable seat 41. The driving member 43 is set as a motor, and a lifting seat 44 is transmission-sleeved on the outer side of the reciprocating screw 42. A rack 45 that meshes with the gear 37 is fixedly provided on the right side of the top of the lifting seat 44. A protruding column 46 is rotatably nested on the front side of the lifting seat 44. A rebound tester 47 is fixedly provided on the bottom of the lifting seat 44. A third guide rod 48 that is fixedly connected to the protruding column 46 is slidingly penetrated on the left side of the top plate of the inverted L-shaped movable seat 41. A receiving groove 49 for accommodating the rack 45 is provided on the right side of the front side of the inverted L-shaped movable seat 41, and the rear parts of the two annular partitions are both located inside the receiving groove 49.

[0051] According to the present technical solution, after the driving member 43 is started, the reciprocating screw 42 is driven to rotate continuously. At this time, the lifting seat 44, which is connected to the reciprocating screw 42, drives the rebound hammer 47 to move downward continuously. As the lifting seat 44 continues to move downward, the bottom end of the rebound hammer 47's impact rod enters the inner side of the adjacent positioning groove 22 and contacts the surface of the dam body inside the positioning groove 22. Subsequently, as the rebound hammer 47 continues to descend, the impact rod is gradually pressed into the rebound cylinder. After the lifting seat 44 moves to the bottom end of the reciprocating groove body outside the reciprocating screw 42, the measurement of the measuring point is completed, and the reading of the rebound hammer 47 is recorded to complete the detection of the measuring point.

[0052] Specifically, as the reciprocating screw 42 continues to rotate, the lifting seat 44 moves up and resets under the drive of the reciprocating screw 42, and the impact rod gradually moves out from the inside of the rebound cylinder during this process. After the lifting seat 44 reaches the top of the reciprocating groove body outside the reciprocating screw 42, the rebound tester 47 moves to the top of the longitudinally adjacent positioning groove 22 under the drive of the inverted L-shaped moving seat 41. Subsequently, as the lifting seat 44 continues to descend, the measuring point located on the inner side of the positioning groove 22 is detected.

[0053] In addition, during the lateral movement of the inverted L-shaped moving seat 41, the gear 37 is driven to move synchronously through the annular partition on the inner wall of the accommodating groove 49 and the side of the gear 37, and the gear 37 drives the limiting slider to move synchronously on the inside of the limiting slide groove 36. The setting of the annular partition can prevent the gear 37 from directly contacting the inner wall of the accommodating groove 49 and causing excessive friction.

[0054] Specifically, during the implementation process, the strength testing method of the dam body of the water conservancy project is as follows:

[0055] Step S1: Determine a measurement area on the dam surface, and then place the device on top of the measurement area. The bottom plate 21 attached to the top of the measurement area directly divides the measurement area into multiple evenly distributed measurement points through multiple positioning grooves 22, eliminating the need for manual line drawing.

[0056] Step S2: Rotate the two pedals 24 from a vertical position to a horizontal position with the pin as the center. At this time, the two pedals 24 are in contact with the surface of the dam body. Then, the device is reinforced by stepping on the pedals 24 or holding the first handle 25.

[0057] Step S3: Start the driving member 43. After the driving member 43 is started, it drives the reciprocating screw 42 to rotate continuously. At this time, the lifting seat 44, which is transmission-connected to the reciprocating screw 42, drives the rebound hammer 47 to move downward continuously. As the lifting seat 44 continues to move downward, the bottom end of the rebound rod of the rebound hammer 47 enters the inner side of the adjacent positioning groove 22 and contacts the dam surface inside the positioning groove 22. Subsequently, as the rebound hammer 47 continues to descend, the rebound rod is gradually pressed into the interior of the rebound cylinder.

[0058] Step S4: After the lifting seat 44 moves to the bottom of the reciprocating groove outside the reciprocating screw 42, the measurement of the measuring point is completed, and the reading of the rebound hammer 47 is recorded to complete the detection of the measuring point. As the reciprocating screw 42 continues to rotate, the lifting seat 44 moves upward and resets under the drive of the reciprocating screw 42, and the impact rod gradually moves out of the rebound cylinder during this process;

[0059] Step S5: The lifting seat 44 moves downward, driving the rack 45 downward. The rack 45 drives the gear 37 to rotate. The gear 37 drives the rotating shaft 34 to rotate synchronously through the limiting slider and the limiting slot 36. However, the traveling wheel 35 does not rotate because it is connected to the rotating shaft 34 via the overrunning clutch.

[0060] Step S6: During the upward reset process of the lifting seat 44, the rack 45, which no longer meshes with the gear 37 due to the downward movement of the lifting seat 44, resumes meshing with the gear 37. Subsequently, as the lifting seat 44 continues to rise, the rack 45 drives the gear 37 to rotate in the opposite direction. At this time, the rotating shaft 34 drives the traveling wheel 35 to travel on the top of the adjacent C-shaped side plate 13. During the travel process, the traveling wheel 35 drives the U-shaped seat 31 to move synchronously along the first guide rod 14 through the rotating shaft 34.

[0061] Step S7: After the lifting seat 44 reaches the top of the reciprocating groove outside the reciprocating screw 42, the rebound tester 47 moves to the top of the longitudinally adjacent positioning groove 22 under the drive of the inverted L-shaped moving seat 41. Subsequently, as the lifting seat 44 continues to descend, the measuring point located inside the positioning groove 22 is tested;

[0062] Step S8, when the rebound tester 47 reaches the upper part of the longitudinal frontmost positioning groove 22 due to multiple movements, the boss 46 enters the inner side of the adjacent avoidance channel 15 under the drive of the lifting seat 44. During the detection process, the boss 46 continues to move down along the adjacent avoidance channel 15 under the drive of the lifting seat 44. During the subsequent upward movement of the lifting seat 44, the boss 46 is driven to move up along the avoidance channel 15 and reset, and then enter the inner side of the adjacent guide channel 16. At this time, due to the guiding effect of the guide channel 16, the inverted L-shaped moving seat 41 slides to the right along the guide groove 32 and the second guide rod 38, thereby driving the rebound tester 47 to move to the upper part of the transverse adjacent positioning groove 22. In this process, the inverted L-shaped moving seat 41 drives the gear 37 to move synchronously through the inner wall of the accommodating groove 49 and the annular partition on the side of the gear 37, and the gear 37 drives the limit slider to move synchronously inside the limit slide groove 36;

[0063] Step S9: The U-shaped seat 31 is pulled by the second handle 39, so that the U-shaped seat 31 located at the front end of the outer side of the first guide rod 14 slides along the first guide rod 14 to the rear end of the outer side of the first guide rod 14, and then driven by the driving member 43, the rebound tester 47 gradually completes the detection of the inner measuring points of multiple positioning grooves 22 in the current vertical column.

[0064] In summary, with the help of the above technical solution of the present invention, the following effects can be achieved:

[0065] 1. The present invention improves detection efficiency and accuracy. The bottom plate 21 and positioning groove 22 of the measuring point positioning mechanism 2 can directly divide the measurement area into evenly distributed measurement points without the need for manual line drawing. The cooperation between the measuring point switching mechanism 3 and the rebound detection mechanism 4 can realize automatic switching of measurement points, avoiding multiple manual adjustments, greatly reducing manpower input, and improving the detection efficiency of multiple measurement points in a single measurement area. At the same time, the guide component accurately guides the movement of the measuring point switching mechanism 3. The rough surface ensures the friction between the traveling wheel 35 and the C-shaped side plate 13, ensuring that the rebound tester 47 accurately moves to the target measurement point. At the same time, the cooperation between the protrusion 46 and the avoidance channel 15 and the guide channel 16 can guide the lateral displacement of the rebound detection mechanism 4 through the mechanical structure, avoiding manual judgment errors, and accurately aligning the rebound tester 47's impact rod with the measurement point, thereby improving the accuracy of the detection data.

[0066] 2. The present invention enhances the stability of the equipment and optimizes the convenience of operation. The reinforcement component of the measuring point positioning mechanism 2 allows the equipment to be fixed by stepping on it or holding it, preventing the equipment from shaking during the test. The sliding cooperation between the inverted L-shaped moving seat 41 and the second guide rod 38 and the guide groove 32 in the rebound detection mechanism 4, as well as the limiting of the protrusion 46 by the third guide rod 48, ensures the stability of the rebound tester 47 during the lifting and movement process, and avoids detection deviations caused by equipment displacement. In addition, the second handle 39 facilitates manual pulling of the measuring point switching mechanism 3 as a whole to move, and cooperates with the automatic switching mechanism to flexibly control the detection path. The driving member 43, such as a motor, drives the reciprocating screw 42 to realize the automatic lifting and lowering of the rebound tester 47, reducing manual operation steps, reducing labor intensity, and making the detection process simpler.

[0067] In summary, the present invention overcomes the problems of existing equipment requiring multiple manual adjustments, non-intuitive measurement point positioning, and low detection efficiency. Through the automated design of the mechanical structure, continuous and accurate detection of multiple measurement points in the measurement area is achieved, while avoiding the obstruction of the positioning structure to the observation of the measurement points, reducing the difficulty of operation, and meeting the efficiency and reliability requirements of the dam strength detection of water conservancy projects.
