Description

Technical Field

[0001] This utility model relates to the field of underwater structure attachment detection technology, specifically to a long-term monitoring device for underwater structure attachments of sea-crossing bridges. Background Technology

[0002] Sea-crossing bridges are in a complex marine environment for a long time, and their underwater structural surfaces are prone to the adhesion of various marine organisms, dirt and debris. These attachments not only affect the appearance of the bridge structure, but more importantly, they pose a serious threat to the structural safety, durability and hydrodynamic performance of the bridge. At present, the detection of attachments on the underwater structure of sea-crossing bridges mostly relies on manual inspection by divers or underwater camera equipment.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220957634U, which discloses a photographic device for underwater bridge structure inspection. The device includes an imaging display and a stainless steel housing. A lower support base is integrated with the stainless steel housing at its lower end. An underwater camera is mounted on the front surface of the lower support base. This utility model allows the underwater camera to rotate 360 ​​degrees underwater by rotating a guide rod, thereby adjusting the angle of the underwater photograph. The guide rod moves up and down within a guide sleeve to adjust the underwater photographing height. This overcomes the problem in existing bridge underwater structure inspections where the underwater camera is sealed and protected by a sealed structure, but the main body of the camera cannot be adjusted in multiple directions during use, resulting in a limited underwater photographing angle.

[0004] While this device can adjust the angle and height of underwater cameras for taking pictures, it cannot automatically clean the underwater camera equipment. The underwater environment is complex, and underwater cameras easily accumulate various impurities, algae, and other substances during use. If they are not cleaned in time, the lens will gradually become blurry, which will seriously affect the subsequent shooting and inspection results, leading to a decrease in the accuracy and reliability of the inspection data. Currently, most cleaning methods rely on manual operation, requiring staff to climb under the bridge to manually clean the camera equipment. This method not only greatly increases the labor intensity of the staff but also poses certain safety risks and has low cleaning efficiency, making it unsuitable for widespread application in actual underwater bridge structure inspection work.

[0008] Furthermore, the pumping assembly includes a suction pump fixedly installed on the top of the water storage tank. The outlet end of the suction pump passes through the water storage tank and extends into its interior. A filter cylinder is fixedly installed on one side of the water storage tank. The output end of the suction pump is connected to the filter cylinder through a pipe. A pumping pipe is fixedly installed at the bottom end of the filter cylinder.

[0009] Furthermore, the cleaning brush assembly includes a cleaning brush rotatably mounted between the two sides of the inner wall of the cleaning frame, and a rotary motor for driving the cleaning brush to rotate is fixedly mounted on one side of the cleaning frame.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown in the figure, an embodiment of the present invention provides a long-term monitoring device for underwater structures of bridges in the sea, comprising: a mounting base 1;

[0023] A fixed frame 2 is installed at the bottom of the mounting base 1. A cleaning frame 3 is fixedly installed on one side of the fixed frame 2.

[0024] Mounting plate 6 is installed at the bottom of the lifting plate 4, and an underwater camera 7 is fixedly installed on one side of the mounting plate 6.

[0025] A water storage tank 9 is fixedly installed on the top of the cleaning frame 3. A water pumping assembly 10 is installed on the top of the water storage tank 9 for pumping seawater into the water storage tank 9. A small water pump 11 is fixedly installed on the top of the cleaning frame 3. The inlet of the small water pump 11 is connected to the water storage tank 9. A water storage pipe 12 is fixedly installed on the outlet of the small water pump 11. Two nozzles 13 are fixedly inserted into the water storage pipe 12.

[0026] A cleaning brush assembly 14 is installed inside the cleaning frame 3 and is used to clean the underwater camera 7.

[0027] The device is fixed to a suitable position under the bridge by the mounting base 1. The fixing frame 2 is installed at the bottom of the mounting base 1, and the cleaning frame 3 is fixedly installed on one side of the fixing frame 2 and the two are connected to each other. The lifting plate 4 is slidably installed between the two sides of the inner wall of the fixing frame 2. The drive component 5 is installed on the fixing frame 2 to drive the lifting plate 4 to move up and down, thereby realizing the lowering of the underwater camera 7 and the flexible adjustment of the shooting height of the underwater camera 7.

[0028] Mounting plate 6 is fixed to the bottom of lifting plate 4. Underwater camera 7 is mounted on one side of mounting plate 6 for capturing images of the underwater structure. Water tank 9 is fixedly mounted on top of cleaning frame 3. Water pumping assembly 10 is mounted on top of water tank 9 for pumping seawater into water tank 9. Small water pump 11 is mounted on top of cleaning frame 3, with its inlet connected to water tank 9 and its outlet connected to water storage pipe 12. Water storage pipe 12 is equipped with two nozzles 13. Cleaning brush assembly 14 is installed inside cleaning frame 3 and, in conjunction with the water sprayed from nozzles 13, is used to clean underwater camera 7. During the inspection process, after underwater camera 7 finishes capturing images, driving assembly 5 moves lifting plate 4 upward, thereby moving underwater camera 7 into cleaning frame 3. Small water pump 11 starts, transporting water from water tank 9 to nozzles 13 through water storage pipe 12. Nozzles 13 spray water to rinse the lens of underwater camera 7, while cleaning brush assembly 14 starts working to clean the lens. This automatic cleaning function effectively solves the problems of existing equipment failing to clean itself after shooting and the lens easily becoming blurry, affecting the shooting effect. It avoids the tedious operation of manual cleaning, reduces the labor intensity of staff, and improves the efficiency and accuracy of testing.

[0029] like Figure 2 As shown, in some embodiments, the drive assembly 5 includes a drive motor 51 fixedly installed on the top of the inner wall of the fixed frame 2, a lead screw 52 fixedly installed on the output end of the drive motor 51, the lead screw 52 being threadedly connected to the lifting plate 4, and the bottom end of the lead screw 52 being rotatably connected to the bottom of the inner wall of the fixed frame 2.

[0030] The drive motor 51 is started, which drives the lead screw 52 to rotate in both directions, thereby raising and lowering the height of the lifting plate 4 that is threaded to it, and in turn, raising and lowering the height of the mounting plate 6 and the underwater camera 7.

[0031] like Figure 2 As shown, in some embodiments, the pumping assembly 10 includes a suction pump 101 fixedly installed on the top of the water storage tank 9. The outlet end of the suction pump 101 passes through the water storage tank 9 and extends into its interior. A filter cylinder 102 is fixedly installed on one side of the water storage tank 9. The output end of the suction pump 101 is connected to the filter cylinder 102 through a pipe. A pumping pipe 103 is fixedly installed at the bottom end of the filter cylinder 102.

[0032] Start the suction pump 101. Its suction force draws seawater through the filter cartridge 102, pipe and water pump 103. When passing through the filter cartridge 102, impurities and dirt can be filtered to obtain clean water, which is then injected into the water storage tank 9. This makes it easier to clean the underwater camera 7 and prevents it from getting worse after washing.

[0033] like Figure 3As shown, in some embodiments, the cleaning brush assembly 14 includes a cleaning brush 141 rotatably mounted between the two sides of the inner wall of the cleaning frame 3, and a rotary motor 142 for driving the cleaning brush 141 to rotate is fixedly mounted on one side of the cleaning frame 3. The cleaning brush 141 is made of a soft material to avoid scratching the lens.

[0034] The rotating motor 142 is started to drive the cleaning brush 141 to rotate, thereby cleaning the lens of the underwater camera 7.

[0035] like Figure 2 As shown, in some embodiments, a servo motor 15 is fixedly installed at the bottom end of the lifting plate 4, and a fixed shaft 16 is fixedly installed at the output end of the servo motor 15. The bottom end of the fixed shaft 16 is fixedly connected to the other side of the mounting plate 6.

[0036] The servo motor 15 is started to drive the fixed shaft 16 to rotate, which in turn drives the mounting plate 6 and the underwater camera 7 on it to rotate, making it easier to capture more underwater structures and attachments.

[0037] like Figure 4 As shown, in some embodiments, a sealing plate 17 is slidably installed at the bottom of the cleaning frame 3, and electric push rods 18 are fixedly installed on both sides of the cleaning frame 3. The output end of the electric push rod 18 is fixedly connected to one end of the sealing plate 17.

[0038] When the underwater camera 7 is not in use, the electric push rod 18 can be activated to retract its telescopic end, thereby driving the sealing plate 17 to close the opening below the cleaning frame 3, thus protecting the underwater camera 7 from long-term exposure to the external environment, preventing corrosion and damage, and reducing its service life.

[0039] like Figure 4 As shown, in some embodiments, rubber wiping blocks 19 are fixedly installed on the bottom of both the fixed frame 2 and the bottom of the closed plate 17. The two rubber wiping blocks 19 are symmetrically distributed, and their adjacent sides are in contact with each other. The inner wall of the rubber wiping block 19 is in contact with the outer periphery of the lifting plate 4.

[0040] When the sealing plate 17 closes the opening, the two rubber wiping blocks 19 merge together, so that when the lifting plate 4 moves upward after being submerged, it can wipe away the dirt adhering to the seawater.

[0041] like Figure 2 As shown, in some embodiments, a rotating plate 20 is rotatably mounted on the bottom of the mounting base 1, and the top of the fixing frame 2 is slidably connected to the bottom of the rotating plate 20.

[0042] The rotating plate 20 is designed to increase the range of motion of the lifting plate 4, thereby increasing the range of motion of the underwater camera 7.
