Description

Technical Field

[0001] The present invention relates to the field of underwater exploration technology, and in particular to an underwater portable imaging device. Background Art

[0002] X-ray imagers are primarily used for security inspections of suspicious items, quickly detecting dangerous goods and other contraband hidden in packages, vehicles, and daily and office supplies. Currently, imagers are primarily used on land, while portable underwater imagers are primarily used during salvage operations. Even in complex environments like mud and weeds, the imager's X-rays can penetrate material, enabling efficient and rapid evidence recovery. This significantly improves efficiency by eliminating the traditional visual and manual search methods of divers, who dive deep into the water.

[0003] To ensure imaging quality during the use of existing imagers, searchers are usually required to hold the handles on both sides of the imager with both hands to ensure stable movement of the imager. When using the imager underwater, as the searchers continue to move underwater, the floating water plants on the bottom of the water can easily interfere with the normal imaging of the imager.

[0010] Furthermore, it also includes a stabilization component; the stabilization component includes a micro water pump, a water inlet pipe, an electrically controlled two-way valve, a delivery pipe and a first connecting pipe; a first cavity is opened in the imager; a micro water pump is fixed in the first cavity; the water inlet of the micro water pump is connected to the water inlet pipe; the water inlet pipe is connected to the outside of the imager; the water outlet of the micro water pump is connected to the electrically controlled two-way valve; the electrically controlled two-way valve is connected to the delivery pipe; a connecting cavity for improving the stability of the imager is opened inside each grip; a first connecting pipe is connected between each connecting cavity and the delivery pipe.

[0011] Furthermore, each handle is provided with a plurality of one-way valves.

[0012] Furthermore, an auxiliary system is also included, which includes an air pump, an electrically controlled three-way valve, a second connecting pipe and an airbag; an air pump is fixedly connected in the first cavity; a second cavity is opened in the imager; an air inlet is opened on the second cavity; a one-way air inlet valve is provided at the air inlet; the air inlet end of the air pump is connected to the second cavity through a pipeline; the air outlet end of the air pump is connected to the electrically controlled three-way valve; one end of the electrically controlled three-way valve is connected to the second connecting pipe; the detection head is circumferentially wrapped with an airbag for protecting the detection head; the interior of the airbag is connected to the second connecting pipe; the expansion direction of the airbag is set to expand downward.

[0013] Furthermore, the other end of the electrically controlled three-way valve is arranged to be connected to the delivery pipe.

This eliminates the need to manually push water plants and improves the efficiency of underwater detection.

[0017] The imager is supported by the bottom plate, grip rod and connecting rod, fixed on the underwater soil, and a gap is maintained between the detection head and the underwater soil, so that the imager can scan the bottom of the water in a static state and avoid the degradation of image quality caused by shaking when holding the imager;

[0018] By filling the connecting cavity with water, the overall weight of the grip is increased, and the weight is transferred to the bottom plate through the connecting rod, thereby increasing the force with which the bottom plate presses on the underwater soil, reducing the shaking of the imager caused by water erosion, improving the overall stability of the imager, and thus improving the imaging quality of the imager.

[0039] It also includes a stabilizing component; the stabilizing component includes a micro water pump 203, a water inlet pipe 204, an electrically controlled two-way valve 205, a delivery pipe 206 and a first connecting pipe 207; a first cavity 1002 is provided in the imager 1; a micro water pump 203 is fixedly connected to the left side of the first cavity 1002; the water inlet of the micro water pump 203 is connected to the water inlet pipe 204; the water inlet pipe 204 is connected to the outside of the imager 1; the water outlet of the micro water pump 203 is connected to the electrically controlled two-way valve 205; the electrically controlled two-way valve 205 is connected to the delivery pipe 206; a connecting cavity 4002 is provided inside each handle 4; a first connecting pipe 207 is connected between each connecting cavity 4002 and the delivery pipe 206.

[0040] Furthermore, in order to reduce the impact of muddy water on imaging quality, four one-way valves 4003 are provided on each handle 4.

[0041] The following is a detailed description of the process of using the imager 1 underwater:

[0042] The imaging principle of the existing imager 1 is usually to emit X-rays from the inside of the imager 1 to the object to be detected. After the X-rays encounter the object to be detected, part of the rays will be reflected back, so that the reflected X-rays are captured by the detection head 1001 and converted into electrical signals by the processor, so that the internal situation of the object to be detected is displayed on the display screen 2. The searcher can carry the imager 1 for transfer by holding the handle 7. During the search process, the searcher needs to hold the handles 4 on both sides with both hands to make the imager 1 move stably to ensure the imaging quality. However, when the imager 1 is used underwater, such as when searching for buried evidence or cultural relics under the water, the searcher usually needs to dive to the bottom of the water with the imager 1, and then hold the handles 4 with both hands to make the detection head 1001 face the bottom of the water, and make the detection head 1 001 is kept at a distance from the bottom of the water to prevent foreign objects such as stones on the bottom of the water from scratching the detection head 1001. Then the search personnel need to keep moving forward slowly, so that the bottom of the water is continuously scanned by the imager 1, so as to search for evidence or cultural relics buried on the bottom of the water. When the search personnel move underwater, when the detection head 1001 of the imager 1 is facing the bottom of the water, the display screen 2 is in a state facing the front, so it is extremely inconvenient for the search personnel to observe the display screen 2 when they need to. For this reason, by setting the display screen 2 to be rotatably connected to the imager 1, based on looking from right to left, the display screen 2 is rotated 90 degrees clockwise so that the display screen 2 is parallel to the bottom of the water. In this way, the search personnel can observe the display information on the display screen 2 while looking at the bottom of the water during diving, thereby improving the efficiency of the search personnel in detecting evidence.

[0043] Furthermore, when there are water plants growing on the bottom of the water, the water plants are constantly floating in the water and are likely to interfere with the imaging quality of the imager 1. At this time, the search personnel need to push away or remove the water plants in the area to be detected, which requires the search personnel to do extra work and reduces the efficiency of detecting the bottom of the water. To this end, the latch 208 is removed from the limit shaft 3001, thereby facilitating the separation of the rotating part 4001 from the limit shaft 3001. From the right to the left, the handle 4 and the connecting rod 5 are rotated 90 degrees counterclockwise with the protruding rod 5002 as the rotation center, and At this time, the protruding block 5003 is located in the second groove 6002, and the protruding block 5003 is limited by the second groove 6002 to ensure that the protruding rod 5002 will not be separated from the fixing ring 6 when rotating. By continuously rotating the grip rod 4 and the connecting rod 5 counterclockwise until the grip rod 4 and the connecting rod 5 are in a horizontal state, the locker 5001 is unlocked to allow the connection between the grip rod 4 and the connecting rod 5 to rotate freely, and then the grip rods 4 on the left and right sides are rotated toward the middle respectively until the rotating parts 4001 of the two grip rods 4 fit together, that is, Figure 11As shown, the locker 5001 is then locked to keep the grip 4 tilted toward the front. In this way, when the search personnel moves forward to an area with aquatic plants, the detection head 1001 is still close to the bottom of the water, so that the two grips 4 are respectively inserted into the roots of the aquatic plants. As the imager 1 continues to move forward, the aquatic plants in front of the imager 1 are pushed to the left and right sides respectively through the two grips 4, so that the soil in the area with aquatic plants is exposed under the detection head 1001, reducing the interference of floating aquatic plants on the imaging of the imager 1, and improving the imaging quality of the imager 1 during underwater mobile search, thereby eliminating the work of manually pushing the aquatic plants and improving the efficiency of underwater detection.

[0044] On this basis, when the imager 1 is used to detect evidence buried underwater, in order to improve the imaging quality of the imager 1, the imager 1 needs to continuously scan the same area in a stationary state. However, it is difficult for a conventional handheld imager 1 to remain stationary underwater. At this time, the rotating part 4001 is sleeved on the adjacent limit shaft 3001, and the latch 208 is also inserted into the through hole of the corresponding limit shaft 3001. Therefore, the rotating part 4001 can only rotate around the limit shaft 3001. Move the left grip 4 clockwise, and bend the right grip 4 counterclockwise. At this time, the lock 5001 is in the locked state, so the connecting rod 5 rotates synchronously with the adjacent grip 4, thereby driving the protruding rod 5002 and the protruding block 5003 to rotate synchronously, so that the protruding block 5003 slides in the adjacent first groove 6001 until the protruding rod 5002 and the protruding block 5003 are disengaged from the fixing ring 6, then the telescopic end of the connecting rod 5 is pulled out, and the bottom plate 201 is rotated to make it in a horizontal state. In this way, Figure 6As shown, the grip 4, the connecting rod 5 and the bottom plate 201 are in the unfolded state, and then the bottom plate 201 is placed on the underwater soil, so that the bottom plate 201, the grip 4 and the connecting rod 5 serve as the support of the imager 1, the imager 1 is fixed on the underwater soil, and a gap is maintained between the detection head 1001 and the underwater soil, so that the imager 1 can scan the bottom of the water in a stationary state, avoiding the reduction of imaging quality caused by shaking when holding the imager 1. On this basis, since the imager 1 is placed on the bottom of the water and is affected by the buoyancy of the water, the force of the bottom plate 201 pressing on the underwater soil is reduced. The water flow is relatively light. When the imager 1 is washed by the water flow, the imager 1 will vibrate, which can easily lead to a decrease in image quality. Therefore, the electronically controlled two-way valve 205 is first controlled to be in an open state, and then the micro water pump 203 is controlled to start pumping water, so that the water outside the imager 1 enters the micro water pump 203 through the water inlet pipe 204, and then passes through the electronically controlled two-way valve 205, the delivery pipe 206 and the first connecting pipe 207 in sequence, and finally enters the connecting chamber 4002, so that the connecting chamber 4002 is filled with water. In this way, the overall weight of the handle 4 is increased, and the weight is transmitted through the connecting rod 5. The handle 4 is used to push the water surface of the imager 1 and the floating mud on the bottom of the water is disturbed, thereby forming turbid muddy water, which will affect the imaging quality of the imager 1. For this reason, a one-way valve 4003 is provided on the handle 4, and the micro water pump 203 is controlled to continuously pump water to the bottom of the water. Water is transported in the communication chamber 4002, and the pressure in the communication chamber 4002 increases, causing the one-way valve 4003 to open, and the water in the communication chamber 4002 is discharged outward through the one-way valve 4003. In this way, the water is continuously discharged from the one-way valve 4003 and blown toward the seaweed outside the grip 4, thereby improving the efficiency of pushing away the seaweed. In addition, the water flows to the left and right sides of the detection area, thereby driving the disturbed muddy water to flow to the left and right sides, accelerating the dispersion of the muddy water, and thus reducing the impact of the muddy water on the imaging quality of the imager 1. When the imager 1 is placed upright on the soil at the bottom of the water for use, it can also be used as shown in the following example. Figure 11 In the state shown, the imager 1 is supported by the grip 4 to improve stability.

[0045] Furthermore, when the underwater soil is located on a slope, if only the bottom plate 201 is pressed against the underwater soil, the bottom plate 201 may slide downward along the slope. Therefore, the raised portion 202 on the bottom plate 201 is manually pulled out. When the bottom plate 201 is placed on the underwater soil, the raised portion 202 is simultaneously driven to be inserted into the underwater soil, thereby increasing the contact area between the bottom plate 201 and the underwater soil and preventing relative slippage between the bottom plate 201 and the underwater soil, thereby improving the stability of the imager 1 when placed on the slope. In addition, the raised portion 202 is initially stored in the bottom plate 201 to prevent the tip of the raised portion 202 from scratching the searcher, thereby improving the safety of the handheld imager 1 when in use.

[0046] Example 2

[0047] On the basis of Example 1, Figure 2 and Figures 8-10 As shown, an auxiliary system is also included, which includes an air pump 301, an electrically controlled three-way valve 302, a second connecting pipe 303 and an airbag 304; the air pump 301 is fixedly connected to the right side of the first cavity 1002; a second cavity 1003 is opened in the imager 1; an air inlet 1004 is opened on the second cavity 1003; a one-way air inlet valve is provided at the air inlet 1004; the air inlet end of the air pump 301 is connected to the second cavity 1003 through a pipeline; the air outlet end of the air pump 301 is connected to the electrically controlled three-way valve 302; one end of the electrically controlled three-way valve 302 is connected to the second connecting pipe 303; the detection head 1001 is circumferentially wrapped with the airbag 304; the interior of the airbag 304 is connected to the second connecting pipe 303; the expansion direction of the airbag 304 is set to expand downward.

[0048] Furthermore, in order to drain the accumulated water in the connecting cavity 4002, avoid the residual water stains that accelerate the rust inside the handle 4, and clear out the silt and other impurities remaining inside the handle 4, thereby extending the service life of the handle 4, the other end of the electric three-way valve 302 is set to be connected to the delivery pipe 206.

[0049] Furthermore, in order to ensure that the accumulated water in the communication chamber 4002 is completely discharged, the position of the one-way valve 4003 located at the lower side is set to be located at the bottom of the communication chamber 4002.

[0050] When the imager 1 is placed on the underwater soil for static scanning, there is a gap between the detection head 1001 and the underwater soil, and the water flow still flows between the detectable head 1001 and the underwater soil. The sand and other suspended matter in the water flow will interfere with the propagation path of the X-rays when passing through the detection head 1001, thereby increasing the noise of the imaging. For this reason, before using the imager 1, it is necessary to first control the external inflation device to deliver air to the air inlet 1004, so that compressed air is stored in the second cavity 1003, and the one-way air inlet valve at the air inlet 1004 is used to prevent the air in the second cavity 1003 from leaking out. When the imager 1 needs to be used for static scanning, the handle 4, connecting rod 5 and bottom plate 201 are unfolded as described in Example 1 to fix the imager 1 on the underwater soil, and after the connecting cavity 4002 is filled with water by the micro water pump 203, the electronically controlled two-way valve 205 is controlled to close to block the micro The water pump 203 is connected to the delivery pipe 206, and the electronically controlled three-way valve 302 is controlled to connect the air pump 301 with the second connecting pipe 303. Then, the air pump 301 is controlled to start working, so that the air in the second cavity 1003 enters the air pump 301 through the pipe. The airflow passes through the electronically controlled three-way valve 302 and the second connecting pipe 303 and finally enters the airbag 304, inflating the airbag 304 and expanding downward until it contacts the bottom soil. As a result, the gap between the detection head 1001 and the bottom soil is filled after the airbag 304 expands. In this way, a relatively sealed space is formed between the detection head 1001, the airbag 304 and the bottom soil, thereby preventing water flow in the area below the detection head 1001, and further preventing the movement of impurities such as sand in the water from interfering with the imaging and causing an increase in noise, thereby improving the imaging quality of the imager 1 and preventing impurities such as sand flowing in the water from scratching the lens of the detection head 1001.

[0051] On this basis, when the underwater search is completed, the imager 1 is first brought to the shore. At this time, the grip 4 is in the storage state, and there is still water in the connecting chamber 4002. For this reason, the air pump 301 is connected to the delivery pipe 206 by controlling the electrically controlled three-way valve 302, and then the air pump 301 is controlled to start working, so that the air in the second cavity 1003 passes through the electrically controlled three-way valve 302 and then flows through the delivery pipe 206 and the first connecting pipe 207 in sequence, and finally enters the connecting chamber 4002. In this way, air is transported into the connecting chamber 4002 by the air pump 301, thereby increasing the pressure in the connecting chamber 4002, and thus squeezing the accumulated water in the connecting chamber 4002 out of the one-way valve 4003. On this basis, when the grip 4 is in the storage state, the grip 4 is in a vertical direction. In this state, by setting the position of the one-way valve 4003 located at the bottom to be located at the bottom of the connecting chamber 4002, it is ensured that the water at the bottom of the connecting chamber 4002 can be discharged from the one-way valve 4003 at the bottom, thereby ensuring that the accumulated water in the connecting chamber 4002 is completely discharged. When the accumulated water in the connecting chamber 4002 is completely discharged, the air pump 301 is continued to be controlled to continuously deliver airflow into the connecting chamber 4002, so that the air in the connecting chamber 4002 is continuously discharged from the one-way valve 4003, thereby drying the inner wall of the connecting chamber 4002 through the airflow, preventing water stains from staying in the connecting chamber 4002 for a long time and accelerating the rust inside the handle 4, and can also clear out impurities such as silt remaining in the handle 4, thereby extending the service life of the handle 4 and reducing maintenance costs.

[0052] It should be noted that the imager 1 as a whole has good waterproof performance. In addition to ensuring that it can be used underwater, it can also be used on land. The scope of use includes but is not limited to scenarios such as public security or border drug control, emergency inspections at transportation hubs, general aviation passenger aircraft and ship inspections. It can quickly scan various types of objects to be inspected, thereby discovering dangerous goods and contraband hidden in the objects, enriching the diversity of the use scenarios of the imager 1.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
