Abstract
Description
Technical Field
[0001] The present application relates to the technical field of dam leakage detection, and in particular to a dam leakage detection device. Background Art
[0002] After a period of use, dams can develop cracks in the submerged sections due to water flow and their own weight, leading to leakage and serious risks to dam safety. Regular inspection and treatment of these cracks are essential. Common methods for dam leakage detection include inkjet and potentiometric (microcurrent) methods. When using the inkjet method, a diver or underwater robot carries an inkjet device to the underwater dam and visually determines the location of the leak. The inkjet device then sprays ink at the suspected leak site and observes the ink's diffusion in the water to determine if the area is leaking. If the dam is leaking, the ink will follow the water flow and diffuse toward the leak. If there is no leak, the ink will diffuse freely. This allows the diver or underwater robot to roughly determine the leak's location based on the water level and diving depth. Current inkjet devices struggle to precisely control the ink volume and velocity, and rely on visual observation of the ink's diffusion, placing high demands on the operator and making accuracy difficult to guarantee.

DETAILED DESCRIPTION
[0028] The following are specific embodiments of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.
[0029] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.
[0030] The embodiment of the present application provides a dam leakage detection device for spraying ink at a possible leakage location of the dam, and then determining whether the dam is leaking and the leakage situation based on the diffusion of the ink in water. Figure 1-Figure 5 The dam leakage detection device includes an ink sac 10, an ejection assembly 40, a visual inspection assembly 50, a nozzle 60, and a controller 100. The ink sac 10 has an inner cavity 11 for holding ink. The ejection assembly 40 includes a cylinder 41, a piston push rod 42, and a telescopic drive element 43. The cylinder 41 has a push chamber 411 within it. The nozzle 60 is connected to the push chamber 411. A connecting passage is provided between the push chamber 411 of the cylinder 41 and the inner cavity 11 of the ink sac 10. The piston push rod 42 is slidably mounted in the push chamber 411 of the cylinder 41. The telescopic drive element 43 is capable of driving the piston push rod 42 to slide back and forth within the push chamber 411, causing the push chamber 411 to draw ink from the inner cavity 11 of the ink sac 10 through the connecting passage and eject the drawn ink through the nozzle 60. The visual inspection assembly 50 is used to detect the diffusion of ink in water. The controller 100 is connected to the telescopic drive element 43 to control the telescopic drive element 43 to move according to a set stroke and speed.
[0031] The inner cavity 11 of the ink sac 10 can accommodate ink. The push chamber 411 of the cylinder 41 is connected to the inner cavity 11 of the ink sac 10. The cylinder 41 and the piston push rod 42 form a piston injection mechanism. This piston injection mechanism draws ink from the ink sac 10 into the push chamber 411 and ejects the absorbed ink by sliding the piston push rod 42 back and forth within the cylinder 41. Specifically, when the piston push rod 42 slides backward within the cylinder 41, negative pressure is generated within the push chamber 411 of the cylinder 41, and the ink in the inner cavity 11 of the ink sac 10 is drawn into the push chamber 411. When the piston push rod 42 slides forward within the cylinder 41, the ink in the push chamber 411 of the cylinder 41 is ejected through the nozzle 60. Furthermore, the sliding movement of the piston push rod 42 is driven by a telescopic drive element. The ink intake and ejection process is controlled by the movement of the piston push rod 42. The ink ejection speed and amount are determined by the movement speed and movement stroke of the piston push rod 42. Therefore, by controlling the movement of the telescopic drive element, a constant-quantity and constant-speed ejection can be achieved. In one embodiment of the present application, the telescopic drive element 43 is an electric push rod, and the controller can achieve a constant-quantity and constant-speed ejection by precisely controlling the movement of the electric push rod.
[0032] Furthermore, after the ink is sprayed into the water, it will spread in the water. The visual detection component 50 can perform visual detection to obtain the diffusion of the ink in the water. The visual detection component can automatically detect the diffusion of the ink in the water without relying on human observation, thereby ensuring accuracy.
[0033] The visual detection component 50 detects the diffusion of ink in water by image acquisition. In one embodiment of the present application, the visual detection component 50 is fixedly disposed on the cylinder body 41 .
[0034] In one embodiment of the present application, the visual inspection assembly 50 includes a housing 51, an image acquisition unit 52, and an image processing unit. The image acquisition unit 52 is used to capture images of ink diffusion in water, and the image processing unit is connected to the image acquisition unit 52. Specifically, the image processing unit and the image acquisition unit 52 can be arranged within the housing 51. The housing 51 can provide protection for the image processing unit and the image acquisition unit 52 in water, allowing them to operate normally underwater for extended periods of time. The image acquisition unit 52 is used to capture the diffusion of ink in water after inkjet printing. The image acquisition unit 52 can be linked to the telescopic drive element 43. When the telescopic drive element 43 drives the piston push rod 42 to slide forward within the cylinder 41, the image acquisition unit 52 can simultaneously begin image acquisition. During operation, the image acquisition unit 52 uploads the captured images of the ink diffusion to the image processing unit. The image processing unit includes an image processor that processes the images captured by the image acquisition unit 52. Through image processing and analysis, the ink diffusion situation can be determined, thereby determining the leakage status of the dam.
[0035] Further references Figure 5 In one embodiment of the present application, the visual detection component 50 further includes a lighting unit 53, which is used to provide lighting for the image acquisition unit 52. The underwater environment has poor lighting conditions, and the configuration of the lighting unit 53 can provide a better lighting environment for the image acquisition unit 52, so that the captured images are clearer and more accurate. In the technical solution of the present application, the visual detection component 50 is configured with multiple lighting units 53, for example, Figure 5 In the structure shown, the visual inspection component 50 is configured with two lighting units 53.
[0036] refer to Figure 1 and Figure 2 In one embodiment of the present application, the dam leakage detection device also includes a first one-way valve 70 and a second one-way valve 80; the first one-way valve 70 is arranged on the connecting channel between the pushing chamber 411 of the cylinder body 41 and the inner cavity 11 of the ink sac 10 to limit the one-way flow of ink from the inner cavity 11 of the ink sac 10 to the pushing chamber 411 of the cylinder body 41; the second one-way valve 80 is arranged between the nozzle 60 and the pushing chamber 411 to limit the one-way flow of ink from the pushing chamber 411 to the nozzle 60.
[0037] Specifically, when the piston push rod 42 slides backward in the cylinder body 41, negative pressure is generated in the push chamber 411 of the cylinder body 41, the first one-way valve 70 is in the forward open state, and the ink in the inner cavity 11 of the ink bag 10 can enter the push chamber 411 through the first one-way valve 70. The second one-way valve 80 is in the reverse closed state, and external water cannot flow back into the push chamber 411 through the nozzle 60. When the piston push rod 42 slides forward in the cylinder body 41, the ink pressure in the push chamber 411 increases, the first one-way valve 70 is in the reverse closed state, and the ink in the push chamber 411 cannot flow back into the inner cavity 11 of the ink bag 10 through the first one-way valve 70. The second one-way valve 80 is in the forward open state, and the ink in the push chamber 411 can be sprayed out through the nozzle 60. Therefore, in the above process, under the action of the first one-way valve 70 and the second one-way valve 80 , the piston push rod 42 slides back and forth in the cylinder body 41 to suck the ink of the ink bag 10 into the pushing chamber 411 and eject the sucked ink.
[0038] refer to Figure 2 and Figure 4 In one embodiment of the present application, the dam leakage detection device further includes an ink sac base 20, to which the open side of the ink sac 10 is mounted. The ink sac base 20 is provided with a filling hole 21 connected to the inner cavity 11 of the ink sac 10, and a plug 22 is disposed on the filling hole 12. The open side of the ink sac 10 is fixed to the ink sac base 20. When ink needs to be added to the inner cavity 11 of the ink sac 10, an operator removes the plug 22 from the filling hole 12 and pours ink into the filling hole 12. After the ink enters the filling hole 12, it flows through the channel in the ink sac base 20 and ultimately into the inner cavity 11 of the ink sac 10. After adding ink, the operator reinstalls the plug 22 on the filling hole 12 to block the filling hole 12.
[0039] Furthermore, the dam leakage detection device further includes a protective housing 30 ; the protective housing 30 is mounted on the ink sac base 20 and wraps the ink sac 10 . The ink sac 10 is usually made of a soft material, and the protective housing 30 can provide support and protection for the ink sac 10 . Figure 4 A schematic diagram of the protective shell 30 is shown. The protective shell 30 is a cylindrical structure. The protective shell 30 and the ink bag base 20 together wrap the ink bag 10.
[0040] refer to Figure 1 and Figure 2In one embodiment of the present application, a connecting tube 90 is provided between the ink sac base 20 and the cylinder body 41. The first end of the connecting tube 90 is connected to the ink sac base 20 and communicates with the inner cavity 11 of the ink sac 10 through the ink sac base 20. The second end of the connecting tube 90 is connected to the cylinder body 41 and communicates with the push cavity 411. Specifically, the connecting tube 90 and the piping structure at both ends of the connecting tube 90 are used to form a connecting channel between the push cavity 411 of the cylinder body 41 and the inner cavity 11 of the ink sac 10. In addition, the connecting tube 90 here can be configured as a curved rigid structure to maintain a fixed relative position between the ink sac base 20 and the cylinder body 41. It should be noted that other piping components can be provided between the first end of the connecting tube 90 and the ink sac base 20 to achieve connection, or they can be directly connected together; other piping components can be provided between the second end of the connecting tube 90 and the cylinder body 41 to achieve connection, or they can be directly connected together. In one embodiment of the present application, a first end of the connecting tube 90 is connected to the ink bag base 20 via a first one-way valve 70 ; a second end of the connecting tube 90 is connected to the cylinder body 41 via a pipe connector 91 .

The visual inspection assembly 50 includes an image acquisition unit 52 and an image processing unit 53. The image acquisition unit 52 uploads the captured images to the image processing unit 53 for recognition and processing. The battery 110 provides power for the telescopic drive element 43 and the visual inspection assembly 50.
