Description

Technical Field

[0001] This invention relates to the field of dam strength testing technology, specifically a hydraulic dam strength simulation testing device. Background Technology

[0002] The design goal of the hydraulic dam strength simulation testing device is to detect the structural strength and stability of the dam by simulating the actual working environment of the dam, and to promptly identify potential safety hazards, thereby ensuring the safety and reliability of the dam.

[0003] Patent publication number CN219284828U relates to a hydraulic dam strength simulation testing device, belonging to the field of hydraulic engineering testing technology. It solves the problem of cumbersome installation of protective mechanisms. The device includes a mounting base and a protective plate, as well as a support frame fixedly connected to the top surface of the mounting base. A top frame for mounting the main body of the strength testing device is fixedly connected to the top port of the support frame. A connecting slider is fixedly connected to the outer edge surface of the main body of the strength testing device. A groove is constructed on the protective plate. When used, this patent allows the protective plate to simultaneously enclose the hydraulic dam sample without any additional operations. Simultaneously, when the main body of the strength testing device returns to its original position, it also moves the protective plate back to its original position. It is convenient to use, requiring no additional operations to install or return the protective plate to its original position, and has good performance.

[0004] In the aforementioned patent, the protective plate can simultaneously enclose the water conservancy dam sample without any additional operations. At the same time, when the main body of the strength testing device returns to its original position, it will also drive the protective plate to return to its original position. It is relatively convenient to use, and the protective plate can be installed or returned to its original position without any other extra operations, which has a good usage effect. However, when measuring the model, it is necessary to position the model and to measure the model from multiple angles according to the tilt angle. Failure to position the model will lead to unreliable measurement results. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a hydraulic dam strength simulation and testing device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic dam strength simulation and testing device, comprising a base plate, a support column fixedly installed on the top of the base plate, a top plate fixedly penetrating the circumferential surface of the support column, a positioning device at the bottom of the top plate, an electric push rod fixedly installed on the top of the base plate, a positioning frame fixedly installed on the top of the base plate, the output end of the electric push rod slidingly penetrating the inner and outer walls of the positioning frame, a circular hole formed on the surface of the positioning frame, a limit hole formed on the surface of the circular hole, an adjusting column sleeved on the inner wall of the circular hole, and a positioning plate slidably installed on the top of the base plate. One end is fixedly installed on the surface of the positioning plate, and the other end of the adjusting column is set as an arc surface. Multiple limiting blocks are fixedly installed on the circumferential surface of the adjusting column. A triangular block is slidably installed on the top of the base plate. The triangular block is fixedly installed on the output end of the electric push rod. A hydraulic rod is fixedly installed on the top of the top plate. A stabilizing device for limiting the speed of the hydraulic rod and a protective device for protecting the stabilizing device are provided at the bottom of the top plate. After the model is positioned, the adjusting column is released. The adjusting column is reset by the reset spring and drives the adjusting column to rotate. After the adjusting column rotates, it no longer contacts the limiting hole and is blocked by the circular limiting block, so that the limiting block is limited.

[0007] According to the above technical solution, the positioning device further includes: a measuring device, a hollow box, and a square plate. The measuring device is set at the bottom of the output end of the hydraulic rod. The hollow box is fixedly installed at the bottom of the top plate. The square plate is fixedly installed at the bottom of the hollow box. The triangular block will contact the model when it moves, and the model will be lifted and moved upward by an angle through the inclined surface design of the triangular block.

[0008] According to the above technical solution, a reset spring is provided between the adjusting column and the circular hole, and the limiting hole contacts the limiting block. The adjusting column is reset by the reset spring.

[0009] According to the above technical solution, the stabilizing device includes: an elastic telescopic rod, a sliding plate, an arc-shaped friction rod, a transmission wedge, a square rod, and a circular vertical rod. The elastic telescopic rod is fixedly installed at the bottom of the top plate. The sliding plate is slidably installed on the inner wall of the hollow box. The sliding plate is fixedly installed at the bottom of the free end of the elastic telescopic rod. The arc-shaped friction rod is slidably installed at the bottom of the sliding plate. The transmission wedge is fixedly installed on the circumferential surface of the output end of the hydraulic rod. The square rod is slidably installed on the top of the square plate. One end of the circular vertical rod is fixedly installed on the top of the square rod, and the other end of the circular vertical rod is fixedly installed on the bottom of the transmission wedge. This increases the resistance when the hydraulic rod moves to the bottom, causing the hydraulic rod to descend slowly due to the increased resistance.

[0010] According to the above technical solution, the stabilizing device further includes: an air cylinder, a sealing plate, an L-shaped connecting rod, and an air inlet. The air cylinder is fixedly installed on the inner wall of the hollow box, the sealing plate is slidably installed on the inner wall of the air cylinder, one end of the L-shaped connecting rod is fixedly installed on the surface of the square rod, and the other end of the L-shaped connecting rod is fixedly installed on the surface of the sealing plate. The air inlets are all opened on the surface of the air cylinder. Since some air inlets no longer flow into the interior of the air cylinder, inflation can only be done slowly when the air cylinder is inflated.

[0011] According to the above technical solution, a first spring is provided between the sealing plate and the air cylinder, and the arc-shaped friction rod is in contact with the output end of the hydraulic rod, so that the sealing plate is reset by the first spring.

[0012] According to the above technical solution, the protective device includes: a sliding inclined block, a fixed plate, a rotating plate, and a blocking plate. The sliding inclined block is slidably installed on the inner wall of the hollow box. The fixed plate is fixedly installed on the side of the sliding inclined block away from the hollow box. The rotating plate is rotatably installed on the side of the fixed plate away from the sliding inclined block. The blocking plate is fixedly installed on the top of the fixed plate. When the sliding inclined block moves, it will contact the arc-shaped friction rod and push the arc-shaped friction rod to move in the direction of the hydraulic rod.

[0013] According to the above technical solution, a torsion spring is provided between the rotating plate and the fixed plate, and the blocking plate contacts the rotating plate, so that the rotating plate is reset by the torsion spring.

[0014] This invention provides a device for simulating and testing the strength of hydraulic dams. It has the following beneficial effects:

[0015] (1) In this invention, the adjustment column no longer contacts the limiting hole after rotation and the limiting block is blocked by the circle so that the limiting block is limited. This allows for quick positioning of the model, which is convenient and efficient. The triangular block will contact the model when it moves, and the inclined surface design of the triangular block will lift the model to the top and move it by an angle. This allows the model to be adjusted according to the required angle before testing, so that the measured values ​​are closer to the data of the real dam and improve the reliability of the device.

[0016] (2) In this invention, the friction between the output end of the hydraulic rod and the output end of the hydraulic rod increases as the output end of the hydraulic rod moves to the bottom, which increases the resistance when the hydraulic rod moves to the bottom and causes the resistance to decrease slowly. This makes the pressure applied to the model by the measuring device more uniform during measurement, reduces the error of the measurement results, and improves the reliability of the device. After the arc friction rod moves, it no longer contacts the hydraulic rod, so that when the output end of the hydraulic rod moves to the bottom, it no longer contacts the arc friction rod. This prevents the output end of the hydraulic rod from being decelerated when it moves to the top, reducing the detection time and improving work efficiency without affecting the detection results.

[0017] (3) In this invention, when the sealing plate is reset by the No. 1 spring, some of the air holes no longer flow with the inside of the air cylinder, so that the air can only be slowly filled when the air cylinder is filled. This allows sufficient time for the hydraulic rod to move to the top, improving the practicality of the device. The sliding block will contact the arc-shaped friction rod and push the arc-shaped friction rod to move towards the hydraulic rod, so that the arc-shaped friction rod contacts the output end of the hydraulic rod again, allowing the device to return to its initial state, thus improving the practicality and portability of the device.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 3 One embodiment of the present invention is a hydraulic dam strength simulation and testing device, comprising a base plate 1, a support column 2 fixedly installed on the top of the base plate 1, a top plate 3 fixedly penetrating the circumferential surface of the support column 2, a positioning device at the bottom of the top plate 3, an electric push rod 41 fixedly installed on the top of the base plate 1, a positioning frame 42 fixedly installed on the top of the base plate 1, the output end of the electric push rod 41 slidingly penetrating the inner and outer walls of the positioning frame 42, a circular hole being formed on the surface of the positioning frame 42, a limit hole being formed on the surface of the circular hole, an adjusting column 43 being sleeved on the inner wall of the circular hole, a positioning plate 44 being slidably installed on the top of the base plate 1, one end of the adjusting column 43 being fixedly installed on the surface of the positioning plate 44, the other end of the adjusting column 43 being set as an arc surface, a plurality of limit blocks 45 being fixedly installed on the circumferential surface of the adjusting column 43, a triangular block 46 being slidably installed on the top of the base plate 1, the triangular block 46 being fixedly installed on the output end of the electric push rod 41, and a hydraulic rod 47 being fixedly installed on the top of the top plate 3. This device can quickly position the model, making it convenient, fast, and improving work efficiency.

[0028] The positioning device also includes a measuring device 48, a hollow box 49, and a square plate 410. The measuring device 48 is located at the bottom of the output end of the hydraulic rod 47. The hollow box 49 is fixedly installed at the bottom of the top plate 3, and the square plate 410 is fixedly installed at the bottom of the hollow box 49. This allows the model to be adjusted according to the required angle before testing, so that the measured values ​​are closer to the data of the real dam and improve the reliability of the device.

[0029] A reset spring is provided between the adjusting column 43 and the round hole, and the limiting hole contacts the limiting block 45. The adjusting column 43 is reset by the reset spring.

[0030] In this embodiment, during operation: the model is placed on top of the base plate 1, and the hydraulic rod 47 is activated. The output end of the hydraulic rod 47 moves to the bottom, which drives the measuring device 48 to move to the bottom. The measuring device 48 moves to the bottom and contacts the model to measure it. The adjusting column 43 is rotated to the top, which drives the limiting block 45 to rotate to the top. After the limiting block 45 coincides with the limiting hole, the adjusting column 43 is pushed inward. The movement of the adjusting column 43 drives the positioning plate 44 to move inward into the positioning frame 42. The positioning frame 42 moves and contacts the model. After the model is positioned, the adjusting column 43 is released, and the adjusting column 43 returns to its original position via a reset spring. The spring reset drives the adjusting column 43 to rotate. After the adjusting column 43 rotates, it no longer contacts the limiting hole and is blocked by the circular limit block 45, which limits the limit block 45. This allows for quick and convenient positioning of the model, improving work efficiency. The electric push rod 41 is activated, and the output end of the electric push rod 41 moves, driving the triangular block 46 to move into the positioning frame 42. The triangular block 46 will contact the model and, through the inclined surface design of the triangular block 46, lift the model to the top and move it by an angle. This allows the model to be adjusted according to the required angle before testing, making the measured values ​​closer to the data of the real dam and improving the reliability of the device.

[0031] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, the bottom of the top plate 3 is provided with a stabilizing device for limiting the speed of the hydraulic rod 47 and a protective device for protecting the stabilizing device. The stabilizing device includes: an elastic telescopic rod 51, a sliding plate 52, an arc-shaped friction rod 53, a transmission inclined block 54, a square rod 55, and a circular vertical rod 56. The elastic telescopic rod 51 is fixedly installed at the bottom of the top plate 3. The sliding plate 52 is slidably installed on the inner wall of the hollow box 49. The sliding plate 52 is fixedly installed at the bottom of the free end of the elastic telescopic rod 51. The arc-shaped friction rod 53 is slidably installed at the bottom of the sliding plate 52. The transmission inclined block 54 is fixedly installed on the circumferential surface of the output end of the hydraulic rod 47. The square rod 55 is slidably installed on the top of the square plate 410. One end of the circular vertical rod 56 is fixedly installed on the top of the square rod 55, and the other end of the circular vertical rod 56 is fixedly installed on the bottom of the transmission inclined block 54. This makes the pressure applied to the model by the measuring device 48 more uniform during measurement, reduces the error of the measurement result, and improves the reliability of the device.

[0032] The stabilizing device also includes: an air cylinder 57, a sealing plate 58, an L-shaped connecting rod 59, and an air inlet 510. The air cylinder 57 is fixedly installed on the inner wall of the hollow box 49, the sealing plate 58 is slidably installed on the inner wall of the air cylinder 57, one end of the L-shaped connecting rod 59 is fixedly installed on the surface of the square rod 55, and the other end of the L-shaped connecting rod 59 is fixedly installed on the surface of the sealing plate 58. The air inlets 510 are all opened on the surface of the air cylinder 57, so that there is sufficient time to complete the movement when the output end of the hydraulic rod 47 moves to the top, thereby improving the practicality of the device.

[0033] A first spring is provided between the sealing plate 58 and the air cylinder 57. The arc-shaped friction rod 53 is in contact with the output end of the hydraulic rod 47, and the sealing plate 58 is reset by the first spring.

[0034] The protective device includes a sliding inclined block 61, a fixed plate 62, a rotating plate 63, and a blocking plate 64. The sliding inclined block 61 is slidably installed on the inner wall of the hollow box 49. The fixed plate 62 is fixedly installed on the side of the sliding inclined block 61 away from the hollow box 49. The rotating plate 63 is rotatably installed on the side of the fixed plate 62 away from the sliding inclined block 61. The blocking plate 64 is fixedly installed on the top of the fixed plate 62, so that the arc-shaped friction rod 53 contacts the output end of the hydraulic rod 47 again, so that the device returns to its initial state and improves the practicality and portability of the device.

[0035] A torsion spring is provided between the rotating plate 63 and the fixed plate 62. The blocking plate 64 contacts the rotating plate 63, and the torsion spring drives the rotating plate 63 to reset.

[0036] In this embodiment, during operation: the output end of the hydraulic rod 47 moves downwards and contacts the arc-shaped friction rod 53. The increased friction between the arc-shaped friction rod 53 and the output end of the hydraulic rod 47 increases the resistance as the hydraulic rod 47 moves downwards, causing it to gradually decrease. This results in a more uniform pressure applied to the model by the measuring device 48 during measurement, reducing measurement errors and improving the reliability of the device. The downward movement of the output end of the hydraulic rod 47 also drives the transmission ramp 54 to move downwards, and the transmission ramp 54 contacts the square rod 55. When the transmission inclined block 54 moves, it causes the square rod 55 to move away from the hydraulic rod 47. The movement of the square rod 55 causes the circular vertical rod 56 to move away from the hydraulic rod 47. The movement of the circular vertical rod 56 causes the arc-shaped friction rod 53 to move away from the hydraulic rod 47. After the arc-shaped friction rod 53 moves, it no longer contacts the hydraulic rod 47. This ensures that when the output end of the hydraulic rod 47 moves to the bottom, it no longer contacts the arc-shaped friction rod 53. This prevents the output end of the hydraulic rod 47 from being decelerated when moving upwards. This reduces the detection time and improves work efficiency without affecting the detection results.

[0037] The movement of the square rod 55 will cause the L-shaped connecting rod 59 to move towards the air cylinder 57. The movement of the L-shaped connecting rod 59 will cause the sealing plate 58 to move. The movement of the sealing plate 58 will compress the air inside the air cylinder 57 and expel it through the inflation hole 510. When the sealing plate 58 is reset by the first spring, since some of the inflation holes 510 are no longer in contact with the inside of the air cylinder 57, inflation inside the air cylinder 57 can only be carried out slowly, allowing sufficient time for the output end of the hydraulic rod 47 to move to the top. The device is moved to improve its practicality. When the transmission inclined block 54 moves to the top, it will contact the rotating plate 63. The rotating plate 63 is blocked by the blocking plate 64, preventing it from rotating to the top. The movement of the rotating plate 63 to the top will drive the sliding inclined block 61 to move to the top. The movement of the sliding inclined block 61 will contact the arc-shaped friction rod 53 and push the arc-shaped friction rod 53 towards the hydraulic rod 47, so that the arc-shaped friction rod 53 contacts the output end of the hydraulic rod 47 again, allowing the device to return to its initial state and improving its practicality and portability.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
