[0032] The present invention provides a dam strength simulation detection device and detection method for water conservancy projects, which has the following beneficial effects:

[0035] 3. When the detection device is used to detect the strength of the water conservancy dam, a reset spring is used to drive the hammer block to impact the impact plate, and the rebound distance of the hammer block is detected. Since the elastic coefficient of the reset spring is known, based on Hu Ke's law, the strength data of the water conservancy dam can be quickly calculated according to the distance moved by the reaction force of the impact rebound, and the detection result is more accurate.

[0036] 4. When conducting strength testing on water conservancy dams, this testing device can realize multi-point measurement on the water conservancy dam without changing the overall position of the device, and can accurately control the distance between each testing point to realize multi-point fixed-distance strength measurement, and the test results are more accurate.

DETAILED DESCRIPTION

[0053] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0054] Example 1: Reference Figure 1-Figure 5 A dam strength simulation detection device for a water conservancy project comprises a base 1 placed on a water conservancy dam 11, a positioning suction cup can be arranged at the lower part of the base 1, and the base 1 is adsorbed on the water conservancy dam 11 by the positioning suction cup to improve the stability of the base 1;

[0055] It also includes: a support base 2 arranged on the base 1, a sliding rod 3 is installed on the support base 2 through an angle adjustment assembly, the angle adjustment assembly includes a steering shaft 13 rotatably installed on the support base 2, and the sliding rod 3 is fixedly installed on the steering shaft 13, a servo motor 10 for driving the steering shaft 13 to rotate is arranged on the support base 2, and the driving end of the servo motor 10 is fixedly connected to the steering shaft 13;

[0056] When the servo motor 10 is started, the steering shaft 13 is driven to rotate, and the rotation of the steering shaft 13 is driven to rotate the sliding rod 3, so that the inclination angle of the sliding rod 3 can be adjusted to be consistent with the inclination angle of the water conservancy dam 11 facing the water surface, thereby improving the accuracy of subsequent strength detection of the water conservancy dam 11;

[0057] An angle dial 12 for detecting the rotation angle of the sliding rod 3 is provided on the support seat 2, and the angle pointer in the angle dial 12 rotates synchronously with the steering shaft 13. When the steering shaft 13 rotates, the angle pointer will be driven to rotate. The rotation position of the steering shaft 13 can be adjusted according to the pointer position of the angle pointer on the angle dial 12, so that the angle adjustment of the sliding rod 3 is more accurate.

[0058] The sliding rod 3 is provided with a sliding adjustment seat 4 through a sliding mechanism. The sliding mechanism includes two limit slide grooves provided on the sliding rod 3. Two limit sliders are fixedly installed in the sliding adjustment seat 4, and the two limit sliders are respectively engaged and installed in the two limit slide grooves. The sliding mechanism is used to limit the sliding adjustment seat 4 so that the sliding adjustment seat 4 can slide stably on the sliding rod 3 without being offset or separated from the sliding rod 3.

[0059] In a further embodiment, the spacing adjustment unit is provided on the sliding rod 3, and is used to accurately adjust the position of the sliding adjustment seat 4 on the sliding rod 3, so as to facilitate strength testing of the water conservancy dam 11 at different positions, increase the number of samples for strength testing, and improve the accuracy of the test results;

[0060] The strength detection unit is arranged on the sliding adjustment seat 4 and realizes position adjustment under the drive of the spacing adjustment unit, and is used for performing accurate multi-position and equidistant strength detection on the water conservancy dam 11 .

[0061] The angle adjustment assembly is used to adjust the angle deflection position of the sliding rod 3, so as to facilitate the strength test of the above-water and underwater parts of the water conservancy dam 11. Figure 2 With the instruction manual Figure 3 As shown in the figure, the wave line shown in the figure is the schematic position of the water surface line. Figure 2 The structural position state of the device when the strength test is performed on the water surface of the water conservancy dam 11 at the upper position of the water surface line after the angle is adjusted. Figure 3After the angle of the device is adjusted, the structural position state of the water surface of the water conservancy dam 11 at the position below the water surface line is tested for strength, so that a comprehensive strength test can be performed on the water surface of the water conservancy dam 11, and the test range is wider.

[0062] Example 2: Reference Figure 1 as well as Figure 5-Figure 7 , the technical solution of this embodiment is different from that of the first embodiment in that: the spacing adjustment unit is composed of a moving component and an adjusting component, wherein the moving component drives the sliding adjustment seat 4 to move in cooperation with the adjusting component;

[0063] A placement plate is fixedly mounted on the sliding rod 3, and the adjustment assembly includes an oil storage tank 8 for storing hydraulic oil fixedly mounted on the placement plate, a push bin 9 is fixedly mounted on the placement plate, an oil filling bin 16 is fixedly mounted on the push bin 9, and an oil filling pipe 18 for conducting hydraulic oil is fixedly connected between the oil filling bin 16 and the oil storage tank 8, an oil guide pipe 20 is fixedly connected in the oil filling bin 16, and the liquid outlet end of the oil guide pipe 20 is located in the push bin 9, a reciprocating piston plate 21 is slidably mounted in the oil filling bin 16, and a control handle 17 is slidably mounted between the reciprocating piston plate 21 and the oil filling bin 16;

[0064] The oil guide pipe 20 and the oil filling pipe 18 are both provided with electric control valves for controlling opening and closing. The opening and closing states of the oil guide pipe 20 and the oil filling pipe 18 are automatically controlled by the electric control valves, so as to facilitate the position and direction of the flow conduction of the hydraulic oil in the oil storage tank 8, the pushing chamber 9 and the oil filling chamber 16.

[0065] When multi-point inspection is required, the operator can pull the control handle 17 to drive the reciprocating piston plate 21 to move leftward in the oil filling tank 16 (see the manual). Figure 7 The following directions are all in the instructions attached. Figure 7 As shown), the oil filling pipe 18 is opened at the same time. At this time, when the reciprocating piston plate 21 moves to the left, the hydraulic oil in the oil storage tank 8 will be sucked into the oil filling bin 16 through the oil filling pipe 18. After the reciprocating piston plate 21 moves to the left to the maximum position, the oil filling pipe 18 is closed and the oil guide pipe 20 is opened at the same time. Then, the control handle 17 is pushed inward to drive the reciprocating piston plate 21 to move right in the oil filling bin 16. When the reciprocating piston plate 21 moves to the right, the hydraulic oil sucked by the oil filling pipe 18 will be injected into the pushing bin 9 through the oil guide pipe 20. Repeat the above steps to continuously inject hydraulic oil into the pushing bin 9, and the hydraulic oil in the pushing bin 9 will increase.

[0066] If it is necessary to reduce the hydraulic oil in the pushing bin 9, it is only necessary to open the oil guide pipe 20 when the reciprocating piston plate 21 moves to the left to absorb oil, and the hydraulic oil in the pushing bin 9 is sucked into the oil filling bin 16 through the oil guide pipe 20, and then the reciprocating piston plate 21 is moved right and the oil filling pipe 18 is opened at the same time, so that when the reciprocating piston plate 21 moves to the right, the hydraulic oil in the oil filling bin 16 will be injected back into the oil storage tank 8 through the oil filling pipe 18 for replenishment, thereby reducing the amount of hydraulic oil in the pushing bin 9.

[0067] In a further embodiment, the moving assembly includes an adjusting piston plate 19 slidably mounted in the push bin 9, a push adjusting rod 14 is slidably mounted between the adjusting piston plate 19 and the push bin 9, and the upper end of the push adjusting rod 14 is fixedly connected to the lower part of the sliding adjustment seat 4, and a compression spring for resetting is fixedly mounted between the push adjusting rod 14 and the sliding adjustment seat 4;

[0068] When the hydraulic oil in the pushing bin 9 gradually increases, it will gradually push the adjusting piston plate 19 to move upward in the pushing bin 9, and at the same time stretch the compression spring, thereby driving the sliding adjusting seat 4 through the pushing adjusting rod 14, so that the sliding adjusting seat 4 moves upward on the sliding rod 3. When the hydraulic oil in the pushing bin 9 decreases, the compression spring will contract and pull the sliding adjusting seat 4, so that the sliding adjusting seat 4 moves downward on the sliding rod 3. The position of the sliding adjusting seat 4 on the sliding rod 3 can be flexibly adjusted to achieve multi-point detection.

[0069] The advantage of using hydraulic oil drive is that the larger flow resistance of hydraulic oil can effectively improve the stability of the movement of the sliding adjustment seat 4, and the incompressible and uniform force transmission characteristics of hydraulic oil can be utilized, so that the stable movement of the sliding adjustment seat 4 can be achieved with only a small force, making it easier to move in the water for strength testing of the water conservancy dam 11.

[0070] A spacing scale plate 15 for measuring the moving distance of the sliding adjustment seat 4 is fixedly installed on the sliding rod 3. The moving distance of the sliding adjustment seat 4 can be regulated by the spacing scale plate 15, so that the distance of each movement of the sliding adjustment seat 4 remains consistent, that is, equal-interval movement detection is achieved. For example, by detecting every 10 cm on the water conservancy dam 11, the moving distance of the sliding adjustment seat 4 can be controlled to be 10 cm each time, so that the strength test can be carried out every 10 cm on the water surface of the water conservancy dam 11. After the test, the data of multiple test points are summed and the average is calculated, so that the accurate strength data of the water conservancy dam 11 above the water surface line or below the water surface line can be calculated.

[0071] Example 3: Reference Figure 1 as well as Figure 8-Figure 13The technical solution of this embodiment is different from that of the second embodiment in that: the strength detection unit is composed of a contact component and a detection component, and the contact component is used to adjust the position of the detection component so that the detection component contacts the water conservancy dam 11 to realize strength detection;

[0072] The contact assembly includes a steering mounting plate 35 rotatably mounted on the sliding adjustment seat 4, and a positioning mechanism is installed between the steering mounting plate 35 and the sliding adjustment seat 4, the positioning mechanism includes a positioning plate fixedly mounted on the sliding adjustment seat 4, a positioning screw 23 is threadedly mounted on the positioning plate, two positioning holes 24 are symmetrically provided on the steering mounting plate 35, and the positioning holes 24 match the positioning screw 23, and a steering control handle is provided on the steering mounting plate 35;

[0073] The positioning screw 23 on the sliding adjustment seat 4 is used to position the steering mounting disc 35 so that the detection component remains stable during strength testing. When the upper water surface line of the hydraulic dam 11 is tested and the lower water surface line needs to be tested, first release the positioning of the steering mounting disc 35 by the positioning screw 23, and then rotate the steering mounting disc 35 half a circle to adjust the position of the detection component to the original symmetrical position. The positioning screw 23 can be used to engage it with another positioning hole 24 on the steering mounting disc 35, and the steering mounting disc 35 can be positioned again to keep it stable during testing.

[0074] A waterproof cylinder 5 for adjusting the position is fixedly mounted on the steering mounting plate 35, and a strength detection tube 6 is provided on the driving end of the waterproof cylinder 5. The waterproof cylinder 5 has a waterproof property and can be used normally underwater. When the waterproof cylinder 5 is started, it will push the strength detection tube 6 to move, so that the strength detection tube 6 contacts and squeezes the side wall of the water conservancy dam 11, and strength detection can be performed.

[0075] In a further embodiment, the detection assembly includes a control detection platform 25 for detection arranged outside the strength detection tube 6, a detection rod 22 and a hammer block 26 are slidably installed in the strength detection tube 6, and the inner diameter of the hammer block 26 is smaller than the outer diameter of the detection rod 22 (that is, the hammer block 26 will hit the detection rod 22 when moving), and a limit rod 30 is fixedly installed on the detection rod 22;

[0076] A chassis 27 is fixedly mounted on the inner wall of the strength detection tube 6, and an impact spring 29 is fixedly mounted between the chassis 27 and the limit rod 30. An impact plate 31 matching the hammer block 26 is fixedly mounted in the strength detection tube 6, and a through hole for the detection rod 22 and the limit rod 30 to pass through is opened on the impact plate 31, and a reset spring 28 is fixedly mounted between the impact plate 31 and the hammer block 26;

[0077] When the strength detection tube 6 squeezes the side wall of the water conservancy dam 11 under the action of the waterproof cylinder 5, the detection rod 22 will first contact the side wall of the water conservancy dam 11. As the waterproof cylinder 5 is gradually pushed, the detection rod 22 will gradually push back into the strength detection tube 6. When the detection rod 22 is pushed back, it will drive the limit rod 30 to push back and squeeze the impact spring 29. The limit rod 30 is fixed with the hammer block 26 in the state, and the two move at the same time. When the limit rod 30 is pushed back, it will drive the hammer block 26 to push back together, and when the hammer block 26 is pushed back and moved, it will stretch the reset spring 28;

[0078] A trigger mechanism is installed between the limit rod 30 and the hammer block 26, and the trigger mechanism includes a micro electric telescopic rod 33 fixedly installed in the hammer block 26, and the hammer block 26 is slidably sleeved on the outside of the limit rod 30, and a limit hole 34 matching the micro electric telescopic rod 33 is opened in the limit rod 30, and an opening and closing trigger rod 32 is fixedly installed on the limit rod 30, and a trigger controller matching the opening and closing trigger rod 32 is fixedly installed on the chassis 27. The trigger controller is activated under the triggering action of the opening and closing trigger rod 32 to control the micro electric telescopic rod 33 to start;

[0079] When the limit rod 30 is pushed back to the maximum position in the strength detection tube 6, it cannot move. At this time, the opening and closing trigger rod 32 on the limit rod 30 will contact the trigger controller on the chassis 27, so that the trigger controller is triggered and started. When the trigger controller is triggered and started, the micro electric telescopic rod 33 in the hammer block 26 is controlled to start. When the micro electric telescopic rod 33 is started, its driving end will shrink and leave the limit hole 34 on the limit rod 30, so that the positioning state of the hammer block 26 can be released.

[0080] At this time, the hammer block 26 will slide on the limit rod 30 and hit the detection rod 22 under the contraction of the return spring 28. When the detection rod 22 is stressed, the impact force will be transmitted to the side wall of the water conservancy dam 11, and a reaction force will be generated to act on the hammer block 26 through the detection rod 22, so that the hammer block 26 rebounds a certain distance. At this time, the control detection platform 25 on the strength detection tube 6 will record the maximum rebound distance of the hammer block 26, and automatically calculate the strength of the water conservancy dam 11 according to the rebound distance and the standard strength conversion table (such as "JGJ / T23-2001" and "JJG817-93", etc.);

[0081] After the preliminary rebound test is completed, the waterproof cylinder 5 starts to drive the strength detection tube 6 to return to its position.
