Description

Technical Field

[0001] This invention relates to the field of hydraulic engineering testing instruments, and in particular to a hydraulic engineering testing instrument and its operating method. Background Technology

[0002] Ultrasonic-based hydraulic testing instruments are devices that utilize ultrasonic technology to test the structural safety of hydraulic structures such as reservoirs, sluices, dams, and water pipelines. Their basic principle is to use the propagation characteristics of ultrasonic waves in a medium to perform non-contact detection and measurement of information such as the volume, shape, material, and internal defects of the hydraulic structure. Specifically, the propagation of ultrasonic waves in hydraulic structures is affected by factors such as structural shape, medium material, and the location, size, and nature of defects. Therefore, during the testing process, it is necessary to select appropriate parameters such as probes, ultrasonic frequencies, and beam angles to test different targets.

[0003] Due to the complex structure of some hydraulic engineering facilities, if a general underwater detector collides with the facility or malfunctions or loses power for other reasons, it requires manual diving to retrieve the detector, which is not only costly but also unsafe.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] This invention provides a hydraulic testing instrument, such as... Figure 1-6As shown, the instrument includes a main shell 1, a control device, a traveling mechanism, and an auxiliary lifting mechanism 4. A transparent shell 3 is provided on the upper surface of the main shell 1, and a camera component 8 is installed inside the transparent shell 3 to facilitate taking pictures through the transparent shell 3. A detector 9 is installed on the outer wall of the transparent shell 3. The control device is located inside the main shell 1 and includes a circuit board 2 and a power supply (not shown in the figure). The power supply provides power to the circuit board 2. The traveling mechanism is located outside the main shell 1, and the control device is electrically connected to the traveling mechanism. External personnel can transmit signals to the circuit board 2 through a control terminal and then control the traveling mechanism to drive the entire detection instrument to move in the water.

[0044] Among them, such as Figure 1-2 As shown, the auxiliary lifting mechanism 4 includes an airbag 41, an air pump 42, and an air cylinder 43. The airbag 41 is located on the outside of the main housing 1, while the air pump 42 and the air cylinder 43 are located inside the main housing 1. The air outlet and air inlet of the air pump 42 are connected to the air cylinder 43 and the airbag 41, respectively. An air outlet pipe 44 connects the air outlets of the airbag 41 and the air cylinder 43. A solenoid valve 45 is connected in series on the air outlet pipe 44. The solenoid valve 45 is separately connected to a power supply and is electrically connected to a control device. The power supply circuit of the solenoid valve 45 can close and open the solenoid valve 45 by detecting the on / off state of the circuit inside the control device, that is, by detecting the on / off state of the circuit inside the circuit board 2. Specifically, when the instrument's circuit board 2 malfunctions in the water or the power supply is not faulty, the control device normally controls the opening and closing of the solenoid valve 45 according to the instrument's own operating mode. Once the instrument's circuit board 2 malfunctions in the water or the power supply fails, the circuit board 2 will not be powered, so the valve of the solenoid valve 45 can be opened, and the gas in the gas storage cylinder 43 will move to the air bag 41, causing the volume of the air bag 41 to expand rapidly. Then, under the action of the air bag 41, it will quickly rise to the water surface for salvage personnel to retrieve, thereby avoiding underwater salvage operations and ensuring their safety.

[0045] Specifically, during use, the instrument mainly operates in four modes: balance mode, descent mode, ascent mode, and emergency mode. The air pump 42 can be turned on and off according to the instrument's operating mode, as follows: In descent mode, the external control unit controls the air pump 42 to compress the gas in the airbag 41 into the gas cylinder 43, thus reducing the instrument's volume. Because the instrument's mass remains almost constant, its density increases, and its buoyancy decreases, facilitating descent and saving significant descent power. In ascent mode, the external control unit controls the solenoid valve 45 to open, allowing the compressed gas in the gas cylinder 43 to gradually return to the airbag 41, thus increasing the instrument's volume and decreasing its density. The smaller size increases buoyancy, facilitating the instrument's ascent and saving significant power. When the instrument needs to remain stationary or move horizontally in the water, it must be switched to balance mode. In this mode, a certain amount of gas must be retained in the air bladder 41 to maintain the instrument's density close to that of water. Once the air bladder 41 contains a certain amount of gas, the air pump 42 and solenoid valve 45 will not operate. In emergency mode, when the main power supply is insufficient or the instrument's circuit board 2 malfunctions, the traveling mechanism cannot propel the instrument normally. The solenoid valve 45 will automatically open or can be manually controlled to open, completely releasing the gas in the gas cylinder 43 into the air bladder 41. This causes the air bladder 41 to inflate to its maximum size, allowing the instrument to rise rapidly and preventing it from remaining in the water.

[0046] Specifically, the aforementioned detector 9 is an ultrasonic detector 9. The top surface of the transparent shell 3 is flat, and the detector 9 is threadedly mounted on the flat surface, thereby increasing the detection range of the detector 9. In addition, for the sake of structural aesthetics, the lower end of the main shell 1 is open, and a second transparent shell 3 is installed at the lower end, which is symmetrically arranged with the upper transparent shell 3. Moreover, most of the gas storage cylinder 43 is located inside the transparent shell 3, and the bottom surface of the lower transparent shell 3 is flat. An ultrasonic detector 9 is also threadedly mounted on this flat surface, increasing the detection range.

[0047] Furthermore, such as Figure 3-4As shown, the instrument also includes multiple support components 5 evenly distributed on the outer wall of the main shell 1. Each support component 5 includes a base, a rotating sleeve 52, a main rod 53, and a sliding rod 54. The base is fixedly mounted on the outer wall of the main shell 1, the rotating sleeve 52 is rotatably mounted on the base, and the main rod 53 is fixedly connected to the outer wall of the rotating sleeve 52. A sliding blind hole 531 is provided at the end of the main rod 53 away from the rotating sleeve 52, and the sliding rod 54 is partially and sealed within the sliding blind hole 531. At least one T-shaped blind hole 522 is provided on the end face of the rotating sleeve 52, and a T-shaped sliding post 55 is sealed and slidably mounted within the T-shaped blind hole 522. A corresponding number of limiting holes 511 for inserting the T-shaped sliding post 55 are provided on the base at corresponding positions. A vent hole 532 is provided at the bottom of the sliding blind hole 531, and the vent hole 532 is connected to the T-shaped blind hole 522. The large-diameter holes of 22 are connected, and the ventilation position of the T-shaped blind hole 522 is located at the bottom of the hole. When the instrument falls to the support plane, the weight of the instrument causes the sliding rod 54 to rotate and slide at the same time. Since the sliding blind hole 531, the T-shaped blind hole 522, the ventilation hole 532 and the sliding blind hole 531 are connected, the sliding rod 54 will reduce the volume of the cavity formed by the sliding blind hole 531, the T-shaped blind hole 522, the ventilation hole 532 and the sliding blind hole 531 while sliding. Under the action of compressed air, the T-shaped sliding column 55 will be forced to slide along the T-shaped blind hole 522 until the end of the T-shaped sliding column 55 is inserted into the limiting hole 511. The sliding rod 54 and the main rod 53 will no longer rotate, so that multiple sliding rods 54 can stably support the entire instrument, providing automated support and convenient use.

[0048] Specifically, the base includes two mounting plates 51 and a central shaft fixed between the two mounting plates 51. One end of each mounting plate 51 is fixed to the outer wall of the main shell 1. A rotating sleeve 52 is sleeved on the central shaft. The rotating sleeve 52 has an annular cavity 521, which communicates with a vent 532. The sidewall of the annular cavity 521 is connected to the bottom of the T-shaped blind hole 522 through a micro-hole 523. Specifically, each end of the rotating sleeve 52 has at least one T-shaped blind hole 522. Correspondingly, each mounting plate 51 has a limit hole 511 at a corresponding position, thereby limiting the... When in position, multiple T-shaped sliding columns 55 can work together with multiple limiting holes 511 to limit the position, thereby making the support component 5 more stable. Specifically, the end of the T-shaped sliding column 55 is a spherical surface, while the limiting hole 511 is a hemispherical structure. Even in the event of an accident, if the end of the T-shaped sliding column 55 slides into the limiting hole 511, the sliding rod 54 can still rotate back to its original position. This avoids the problem that when support is not needed, due to other factors, the sliding rod 54 may only rotate, and the end of the T-shaped sliding column 55 may slide into the limiting hole 511, causing the sliding rod 54 to be unable to rotate back to its original position.

[0049] Specifically, the sliding blind hole 531 is a T-shaped hole. The end of the sliding rod 54 located in the large-diameter hole of the sliding blind hole 531 is fixedly fitted with an annular sealing ring 56. The upper end of the annular sealing ring 56 is sealed, and the end of the sliding rod 54 is fitted inside. The annular sealing ring 56 is sealed and connected to the side wall of the large-diameter hole in the sliding blind hole 531. The annular sealing ring 56 also serves as a limit to prevent the sliding rod from falling out of the sliding blind hole 531.

[0050] Furthermore, the end face of the sliding rod 54 located outside the main rod 53 is connected to a universal ball seat. The end face of the universal ball seat away from the sliding rod 54 is provided with a movable claw 57. Due to the presence of the universal ball seat, the movable claw 57 can make stable contact with the support surface. The movable claw 57 can make more firm contact with the support surface, and the support is more stable.

[0051] Furthermore, the support assembly 5 also includes an upper flexible support base 58 and a lower flexible support base 59. Both the upper flexible support base 58 and the lower flexible support base 59 are located on the outer wall of the main shell 1 and on the upper and lower sides of the base. Both the upper flexible support base 58 and the lower flexible support base 59 are provided with arc grooves that run vertically through the main rod 53 for placement. When the instrument is suspended in the air, the main rod 53 can rotate. When the instrument is placed facing up or down, the support assembly 5 will automatically flip due to gravity. The upper flexible support base 58 and the lower flexible support base 59 can reduce the impact force generated by the support assembly 5 when flipping.

[0052] Furthermore, such as Figure 1 , 3 As shown, the outer wall of the main housing 1 is provided with multiple evenly distributed side arms 7 each having a central through hole. The traveling mechanism includes multiple power components 6 evenly distributed outside the main housing 1. The power components 6 include propeller propulsion components 61. The multiple propeller propulsion components 61 are correspondingly disposed on the ends of the multiple side arms 7 away from the main housing 1. The propeller propulsion components 61 are electrically connected to the control device. Specifically, the power components 6 also include a first servo motor 62 and a rotating shaft 63. The first servo motor 62 is disposed inside the side arm 7. The output shaft of the first servo motor 62 is connected to the rotating shaft 63. One end is sealed and rotatably located at the end of the side arm 7 away from the main housing 1, and the other end extends out of the side arm 7 and is connected to the propeller propulsion assembly 61. The first servo motor 62 is electrically connected to the control device. Thus, the first servo motor 62 can drive the rotating shaft 63 and then drive the entire propeller propulsion assembly 61 to rotate, thereby adjusting the direction of propulsion and facilitating the movement of the instrument. Specifically, the propeller propulsion assembly 61 is existing technology and includes a propulsion sleeve, a propeller, and a motor. The propeller and the motor are both installed inside the propulsion sleeve, and the motor is used to drive the propeller to rotate.

[0053] Furthermore, there are multiple airbags 41, each corresponding to one of the multiple side arms 7 on their outer periphery. In this embodiment, there are four airbags, each of which is an annular airbag 41, and each annular airbag 41 is connected by multiple airbag rings. Each airbag ring can inflate to a certain volume. Specifically, there are four side arms 7, and four corresponding propeller propulsion components 61, which are evenly distributed on the outside of the main shell 1. There are also four airbags 41. An air inlet pipe 46 is connected to the air inlet of the air pump 42. A six-way connector 47 is connected between the air outlet pipe 44 and the air inlet pipe 46. Each of the four airbags 41 is connected to a ventilation pipe 48. The central through hole of the side arm 7 is connected to the main shell 1. The end of the ventilation pipe 48 near the airbag 41 is located in the central through hole, passes through the side arm 7 and connects to the airbag 41 on it. All four ventilation pipes 48 are connected to the six-way connector 47, thus forming a complete ventilation pipe 48. The pipe structure is simple.

[0054] Preferably, such as Figure 6 As shown, the camera assembly 8 includes a camera 81, a first U-shaped frame 82, a second U-shaped frame 83, a second servo motor 84, a mounting cylinder 85, and a third servo motor. The mounting cylinder 85 is installed on the upper end of the main housing 1, the third servo motor is installed inside the mounting cylinder 85, the second U-shaped frame 83 is located above the mounting cylinder 85 and connected to the output end of the third servo motor, the first U-shaped frame 82 is located inside the second U-shaped frame 83, the second servo motor 84 is installed inside the first U-shaped frame 82, a rotating sleeve is provided on the inner side wall of the second U-shaped frame, the output shaft of the second servo motor 84 passes through the first U-shaped frame 82 and is rotatably connected to the rotating sleeve, the camera 81 is mounted on the first U-shaped frame 82, and the second servo motor 84 and the third servo motor are electrically connected to the control device. During operation, the third servo motor can control the second U-shaped frame 83 to rotate circumferentially in the vertical direction, and the second servo motor 84 can control the first U-shaped frame 82 to rotate circumferentially in the horizontal direction, thereby enabling the camera 81 to shoot from multiple directions, making it more convenient to use. Moreover, the camera 81 is a commercially available binocular camera 81.

[0055] Specifically, the second U-shaped frame 83 has a side bracket 86 on its side end, and a lighting component 87 is provided on the side bracket 86. The lighting component 87 is electrically connected to the control device and is powered by a power source to provide supplementary lighting and prevent insufficient light in the water. Specifically, the lighting component 87 can be a commercially available lighting fixture.

[0056] This embodiment also provides a method for operating a hydraulic testing instrument, including a descent mode, an ascent mode, a balance mode, and an emergency mode;

[0057] In descent mode, when the instrument is just submerged, the external control terminal turns on the air pump 42 to compress the gas in the air bag 41 into the air storage bottle 43. At the same time, the travel mechanism is adjusted to the descent state, that is, the first servo motor 62 rotates the propeller propulsion assembly 61 through the rotating shaft 63, so that the propulsion direction is in the descent direction.

[0058] In ascending mode, when the instrument needs to ascend, the external control terminal opens the solenoid valve 45. By controlling the opening of the solenoid valve 45, the compressed gas in the gas storage cylinder 43 gradually returns to the air bag 41. At the same time, the traveling mechanism is adjusted to the ascending state. That is, the first servo motor 62 rotates the propeller propulsion assembly 61 through the rotating shaft 63, so that the propulsion direction is in the ascending direction. At the same time, the ascending speed of the instrument can be accelerated by controlling the opening of the control valve and raising the propeller propulsion assembly. Thus, under the combined action of the air bag 41 and the propeller propulsion assembly 61, ascending power is saved.

[0059] In the balance mode, gas is left in the airbag 41. In conjunction with the use of the propeller propulsion assembly 61, the first servo motor 62 controls the thrust direction of the two opposing propeller propulsion assemblies 61 to be upward and the thrust direction of the other two propeller propulsion assemblies 61 to be downward. This ensures that the magnitude of the instrument's weight is equal to the sum of the magnitude of the buoyancy and the thrust generated, thus ensuring that the instrument is in a hovering state. When tilting occurs, the thrust of the corresponding propeller propulsion assembly 61 increases.

[0060] In emergency mode, if the main power supply is insufficient or the circuit board 2 malfunctions, the power supply circuit inside the solenoid valve 45 will detect this and control its own circuit to fully open the solenoid valve 45. The compressed gas in the gas cylinder 43 will quickly return to the airbag 41, causing the airbag 41 to expand rapidly and rise to the water surface as quickly as possible, making it easier for salvage personnel to retrieve the gas.

[0061] Using the above operating method, the instrument operates faster during ascent and descent, is more stable during filming, and can automatically rise to the water surface in case of emergency for personnel to retrieve, making it more convenient to use overall.

[0062] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
