Description

Technical Field

[0001] The invention belongs to the technical field of underwater cleaning, and in particular relates to an external device for preventing biological attachment of underwater equipment. Background Art

[0002] The description in this section merely provides background information related to the disclosure of this application and does not constitute prior art.

[0003] Solid structures used in marine environmental monitoring are susceptible to biofouling as soon as they are placed in water. Marine equipment, such as water quality meters, acoustic instruments, and temperature and pressure sensors, can become biofouled when used continuously in seawater for extended periods, affecting detection precision and accuracy, significantly impacting operations and maintenance. Biofouling and sediment coverage of observation equipment have long been a major concern.

[0004] Traditional solutions include wrapping sensors and other instruments with copper mesh, or applying antifouling paint on the sensor surface. However, these methods also have obvious disadvantages. First, the continuous adhesion of the copper mesh will cause changes in the water quality around the sensor, affecting the accuracy of sampling parameters such as water quality. Second, antifouling paint can only be applied to the outer shell, and the more sensitive probe parts cannot be painted, which will still cause biological attachment.

[0005] Numerous solutions have been proposed in the prior art to address the aforementioned biofouling problem, such as US Pat. No. 10786584B2, which provides an anti-biofouling solution for underwater lighting fixtures. This solution involves immersing the fixture in seawater and exposing it to the surrounding environment. In this patent, the main window is isolated from the surrounding environment by an auxiliary window member. Ultraviolet radiation is directed from a source within the modified device to the outer surface of the auxiliary window member, thereby transmitting the ultraviolet radiation to the outer surface of the auxiliary window. This solution addresses the biofouling problem by preventing organisms from attaching to the fixture through ultraviolet irradiation, while also avoiding water pollution caused by antifouling paint and other materials. However, this solution still has room for improvement in terms of sediment coverage.

[0006] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0007] The purpose of the present invention is to provide an external device for preventing underwater equipment from adhering to biological adhesion, which can solve the problem of underwater organisms adhering to marine environment monitoring equipment, and at the same time avoid mud and sand coverage, effectively remove adhesion over a large range and have little impact on the environment of the monitoring area.

[0008] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: an external device for preventing biological attachment of underwater equipment, comprising:

[0009] A second substrate is provided with a first hole.

[0010] The first substrate is arranged on the upper part of the second substrate. The first substrate and the second substrate are connected by surrounding connecting rods. The first substrate and the second substrate are preferably made of light-transmitting materials, such as quartz glass.

[0011] A first protective cover is provided on the upper portion of the first substrate, and at least one ultraviolet lamp is installed inside the first protective cover.

[0012] The second base plate has an annular structure and can be assembled with the target marine environment monitoring device via fasteners to enable the underwater equipment anti-fouling external device of the present invention to be installed on the marine environment monitoring device. A gap is maintained between the second base plate and the first base plate to ensure water flow, which facilitates the flushing of the surface of the marine environment monitoring device and the first and second base plates, preventing the accumulation of sediment near the second and first base plates.

[0013] The present invention realizes ultraviolet irradiation by setting up an ultraviolet lamp to prevent organisms from attaching to the marine environment monitoring device, and effectively removes biological insect eggs, larvae, etc. attached to the surface of the marine environment monitoring instrument. It should be noted that the ultraviolet lamp is turned on at a timed manner to avoid continuous opening to affect the organisms in the surrounding environment where the device is installed.

[0014] The present invention increases the distance between the ultraviolet lamp and the marine environment monitoring device by installing the first substrate and the second substrate, thereby expanding the irradiation range of the ultraviolet lamp, ensuring that the ultraviolet lamp is maximized within the effective irradiation range of the ultraviolet lamp, and expanding the range of removing attachments on the marine environment monitoring equipment. The way the first substrate and the second substrate maintain a distance can reduce or minimize the relevant vibration, heat, etc. of the installed marine environment monitoring device transmitted to the ultraviolet lamp inside the first protective cover, thereby avoiding the occurrence of loosening, etc. In addition, by arranging the first substrate on the marine environment monitoring device and connecting it to the second substrate through a connecting rod, a collision buffering effect can be achieved for the marine environment monitoring device in the installation area, specifically by absorbing collision energy through the deformation of the connecting rod.

[0015] According to one embodiment of the present invention, a first motor is provided in the middle of the first substrate, and an output shaft is provided at the output end of the first motor. The output shaft can pass through the first substrate and enter the space between the first substrate and the second substrate. The output shaft and the first substrate are connected and fixed by bearings and sealing rings. A first blade is arranged around the output shaft between the first substrate and the second substrate. By providing the first motor, the output shaft is driven in a timely manner to drive the rotation of the first blade, thereby driving the rotational flow of the water around the first and second substrates. The vortex is used to flush and clean the surface of the marine environment monitoring device in the vicinity of the assembly position of the device, for example, to remove organisms attached to the surface, mud and sand accumulated on the surface, etc., and the vortex formed can also flush and clean the device itself, that is, to achieve self-cleaning. The present invention effectively expands the scope of removing attachments from marine environment monitoring equipment through a combination of vortex cleaning and ultraviolet sterilization.

[0016] According to one embodiment of the present invention, the first protective cover is a cylindrical structure with a hollow interior. The ultraviolet lamp is located in the upper portion of the first protective cover, and the surface of the first protective cover is surrounded by through holes. The first protective cover protects the ultraviolet lamp and reduces the possibility of damage. The through holes surrounding the surface of the first protective cover not only facilitate the transmission of ultraviolet rays, but also enhance the interference effect of water passing through the surface of the first protective cover, increase the contact between the water flow and the surface of the first protective cover, and enhance the flushing effect of the water flow on the surface of the first protective cover.

[0017] The ultraviolet wavelength of the ultraviolet lamp used in the present invention is in the range of 240-280 nm. The wavelength within this range can kill and destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing growth cell death and (or) regenerative cell death.

[0018] According to one embodiment of the present invention, the lower portion of the first protective cover is connected to the first base plate via a second tube with two through-holes. The first base plate is provided with a first tube at the bottom. The first tube is a bent tube with two through-holes. One end of the first tube is connected to the second tube. The diameters of the two ends of the second tube are different. Specifically, the diameter of the end of the second tube connecting to the first protective cover is larger than the diameter of the other end, and the other end is located in the space between the first and second base plates. Water can enter the space below the first base plate through the holes on the surface of the first protective cover, thereby facilitating water flow and improving the cleaning effect. Similarly, water below the first base plate can enter the interior of the first protective cover and flow out of the holes on its surface, achieving internal flushing and cleaning. This design also reduces clogging of the holes on the surface of the first protective cover. In particular, when the first motor drives the first blade to rotate, some water can be driven from the first tube into the first protective cover and discharged from the first protective cover. This flushing and cleaning of the first and second tubes, as well as the interior of the protective cover, is achieved, while preventing clogging of the holes in the first protective cover. Water discharged from the interior of the first protective cover can enhance fluid flow around the first protective cover, improving the water cleaning effect.

[0019] According to one embodiment of the present invention, a flow diversion component is provided inside the second tube body, and the flow diversion component includes:

[0020] A rubber plate, the side of the rubber plate is fixedly connected to the inner wall of the second tube, and the surface of the rubber plate is provided with through holes;

[0021] The third sleeve has two through-holes, one end of the third sleeve is located below the rubber plate, and the other end is located above the rubber plate. The surface of the third sleeve is surrounded by second blades.

[0022] The upper portion of the third sleeve is connected to the first sleeve through a second sleeve with two ends penetrated, the first sleeve is penetrated at both ends, and the side of the first sleeve is staggered with diversion holes.

[0023] By arranging a diversion component inside the second tube body, the upward fluid from the second tube body is guided, so that the upward water flow can pass through the third sleeve and enter the second sleeve upward. Part of the water flow is divided into multiple streams after passing through the rubber plate. When the rubber plate faces the impact of excessive water flow, it can form a deformation to expand the diameter of its surface hole. The water body entering the second cylinder body further flows upward and is discharged from the top and periphery of the first cylinder body. In this process, the water body can form a vortex flow along the second blade outside the third sleeve and flow upward, and part of the water flow can be discharged from the diversion hole of the first sleeve, which is easy to use. An upward turbulent flow is formed inside the second tube body, which forms turbulence inside the second tube body and the first protective cover, thereby improving the water flushing and cleaning effect and avoiding blockage of each hole. More importantly, when the ultraviolet lamp is powered on, the turbulent flow formed inside the second tube body and the first protective cover can easily change the angle of ultraviolet irradiation, so as to increase the irradiation range and avoid blind spots. In addition, by arranging a diversion component inside the second tube body, it is possible to prevent or reduce the entry of organisms into the second tube body and the first protective cover, and the circulation of objects is restricted by the rubber plate, which also serves as an interception for sediment.

[0024] According to one embodiment of the present invention, a connecting ring is coaxially fixed to the bottom of the first sleeve, to which a first curved rod is connected. The first curved rod is arranged perpendicular to the axis of the connecting ring, and its two ends are bent and connected to the annular surface of the connecting ring. The structure of the connecting ring and the first curved pipe can divert water flow from the second cylinder upward or from the first protective cover downward, thereby reducing the occurrence of turbulent water flow. In addition, the first curved pipe acts as an interception and restriction, preventing or reducing the possibility of organisms and objects passing through.

[0025] According to one embodiment of the present invention, the connecting rod is hinged with two swinging plates, and a spring is provided between the swinging plates. The swinging plate is preferably arranged on the side of the connecting rod away from the first blade. By arranging the swinging plate on the connecting rod, it is possible to guide the water body formed by the rotation of the first blade. Specifically, the water flow forms a vortex under the rotation movement of the first blade and is discharged outward from the space between the connecting rods. In this process, the water flow can pass through the swinging plates, and the swinging plates between adjacent connecting rods limit the water flow discharge space, thereby increasing the outward discharge flow rate of the water flow and improving the water body's flushing effect on the surface of the marine monitoring equipment. At the same time, according to the outward discharge flow rate of the water body, the spring can adjust the spacing between the swinging plates to control the water body discharge channel space. In this process, the swinging plate swings continuously with the spring, which is easy to form vibration, which helps to drive away the organisms around the device and remove surface dirt. It is also beneficial for the vibration to be transmitted to the connecting rod, and then transmitted to the first substrate and the second substrate to drive away the organisms attached to the upper part.

[0026] According to one embodiment of the present invention, a battery is provided on the upper portion of the first motor, and the battery is electrically connected to the first motor and / or the ultraviolet lamp. The first motor and the ultraviolet lamp are powered by the battery.

[0027] According to one embodiment of the present invention, the battery is connected to the photovoltaic panel via a connecting line, and the photovoltaic panel supplies power to the battery, so that the device can work continuously for a long time.

[0028] According to one embodiment of the present invention, the first protective cover is made of a light-transmitting material, such as quartz glass, to enable ultraviolet rays to irradiate the surrounding area.

[0029] Preferably, the ultraviolet lamp is turned on and off intermittently, and is continuously powered on for 30 minutes to 60 minutes every 24 hours.

[0030] The present invention utilizes ultraviolet light to prevent organisms from attaching to marine environment monitoring equipment, effectively removing insect eggs, larvae, and other organisms adhering to the surface of the equipment. This advantageous effect is achieved by combining cyclone cleaning with ultraviolet sterilization to effectively expand the range of organism removal from marine environment monitoring equipment. This solves the problem of underwater organisms attaching to marine environment monitoring equipment while preventing sediment buildup. This effectively removes organisms over a wide area with minimal environmental impact in the monitoring area. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The technical solution of the present invention is further described in detail below with reference to the specific embodiments and the accompanying drawings:

[0043] Example 1:

[0044] See attached Figure 1 , Attachment Figure 3-4 As shown, the underwater equipment anti-biological adhesion external device includes:

[0045] The second substrate 45 has a first hole 46 formed thereon.

[0046] The first substrate 40 is disposed on the upper portion of the second substrate 45 . The first substrate 40 and the second substrate 45 are connected via a surrounding connecting rod 41 . The first substrate 40 and the second substrate 45 are preferably made of a light-transmitting material, such as quartz glass.

[0047] A first protective cover 30 is provided on the first substrate 40 , and at least one ultraviolet lamp 33 is installed inside the first protective cover 30 .

[0048] The second base plate 45 is annular in structure and can be assembled with the target marine environment monitoring device via fasteners to allow the underwater equipment anti-fouling external device of the present invention to be installed on the marine environment monitoring device. A gap is maintained between the second base plate 45 and the first base plate 40 to ensure water circulation, which facilitates the scouring effect of water on the surface of the marine environment monitoring device and the first and second base plates 40, 45, preventing the accumulation of sediment and other debris near the second base plate 45 and the first base plate 40.

[0049] The present invention realizes ultraviolet irradiation by setting an ultraviolet lamp 33 to prevent organisms from attaching to the marine environment monitoring device, and effectively removes biological insect eggs, larvae, etc. attached to the surface of the marine environment monitoring instrument. It should be noted that the ultraviolet lamp 33 is turned on at a timed interval to avoid continuous opening to affect the organisms in the surrounding environment where the device is installed.

[0050] The present invention increases the distance between the ultraviolet lamp 33 and the marine environment monitoring device by installing the first substrate 40 and the second substrate 45, thereby expanding the irradiation range of the ultraviolet lamp, ensuring maximum utilization of the ultraviolet lamp within the effective irradiation range of the ultraviolet lamp 33, and expanding the range of removing attachments on the marine environment monitoring equipment. The way in which the first substrate 40 and the second substrate 45 maintain a distance can reduce or minimize the relevant vibration, heat, etc. of the installed marine environment monitoring device transmitted to the ultraviolet lamp 33 inside the first protective cover 30, thereby avoiding the occurrence of loosening, etc. In addition, by arranging the first substrate 40 on the marine environment monitoring device and connecting it to the second substrate 45 through the connecting rod 41, a collision buffering effect can be achieved for the marine environment monitoring device in the installation area, specifically by the deformation of the connecting rod 41 to absorb the collision energy.

[0051] See attached Figure 2 As shown, a first motor 20 is disposed in the middle of the first base plate 40. An output shaft 21 is disposed at the output end of the first motor 20. The output shaft 21 can pass through the first base plate 40 and enter the space between the first base plate 40 and the second base plate 45. The output shaft 21 is fixed to the first base plate 40 via a bearing and a sealing ring. A first blade 22 is disposed around the output shaft 21 between the first base plate 40 and the second base plate 45. The first motor 20 is provided to periodically drive the output shaft 21, driving the rotation of the first blade 22. This in turn drives the rotational flow of the water surrounding the first base plate 40 and the second base plate 45. The vortex is used to flush and clean the surface of the marine environment monitoring device in the vicinity of the device's assembly location, for example, removing attached organisms and accumulated sediment. The resulting vortex also flushes and cleans the device itself, achieving self-cleaning. The present invention effectively expands the scope of attachment removal for marine environment monitoring equipment through the combination of vortex cleaning and ultraviolet disinfection.

[0052] See attached Figure 3 、 4As shown, the first protective cover 30 is a cylindrical structure with a hollow interior. The UV lamp 33 is located in the upper portion of the first protective cover 30, and through-holes are formed around the surface of the first protective cover 30. The first protective cover 30 protects the UV lamp 33 and reduces the possibility of damage. The through-holes formed around the surface of the first protective cover 30 not only facilitate the transmission of UV light but also enhance the interference effect of water passing through the surface of the first protective cover 30, increasing the contact between the water flow and the surface of the first protective cover 30 and improving the flushing effect of the water flow on the surface of the first protective cover 30.

[0053] The ultraviolet wavelength of the ultraviolet lamp 33 used in the present invention is in the range of 240-280 nm. The wavelength within this range can kill and destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing growth cell death and (or) regenerative cell death.

[0054] See attached Figure 2-4 As shown, the lower part of the first protective cover 30 is connected to the first substrate 40 through a second tube body 32 with both ends passed through. A first tube body 31 is provided at the bottom of the first substrate 40. The first tube body 31 is a bent tube with both ends passed through. One end of the first tube body 31 is connected to the second tube body 32. The diameters of the two ends of the second tube body 32 are different. Specifically, the diameter of the connection end of the second tube body 32 and the first protective cover 30 is larger than the diameter of the other end, and the other end is provided in the space between the first substrate 40 and the second substrate 45. Water can enter the space below the first substrate 40 below through the holes on the surface of the first protective cover 30, which helps the water flow in the space below the first substrate 40 to improve the cleaning effect. Similarly, the water under the first substrate 40 can also enter the interior of the first protective cover 30 and flow out from its surface holes to achieve an internal flushing and cleaning effect. This design can also reduce the blockage of the holes on the surface of the first protective cover 30, especially when the first motor 20 drives the first blade 22 to rotate, it can drive part of the water to enter from the first tube 31 and be discharged from the first protective cover 30, thereby achieving flushing and cleaning of the first tube 31, the second tube 32 and the inside of the protective cover 30, and avoiding blockage of the holes on the first protective cover 30. The water discharged from the inside of the first protective cover 30 to the outside can enhance the fluid flow around the first protective cover 30 to improve the water cleaning effect.

[0055] See attached Figure 4-6 As shown, a flow diversion component 50 is provided inside the second tube body 32, and the flow diversion component 50 includes:

[0056] A rubber plate 57, the side of the rubber plate 57 is fixedly connected to the inner wall of the second tube 32, and the surface of the rubber plate 57 is provided with through holes;

[0057] The third sleeve 55 is provided with two through-holes at both ends. One end of the third sleeve 55 is provided below the rubber plate 57, and the other end is provided above the rubber plate 57. The surface of the third sleeve 55 is surrounded by second blades 56.

[0058] The upper portion of the third sleeve 55 is connected to the first sleeve 51 through a second sleeve 54 with two ends penetrated therethrough. The first sleeve 51 has two ends penetrated therethrough, and the side surfaces of the first sleeve 51 are staggered with diversion holes 52 .

[0059] By setting a diversion component 50 inside the second tube body 32, the upward fluid from the second tube body 32 is guided, so that the upward water flow can pass through the third sleeve 55 and enter the second sleeve 54. Part of the water flow is divided into multiple streams after passing through the rubber plate 57. When facing the impact of excessive water flow, the rubber plate 57 can be deformed to expand the diameter of its surface hole. The water entering the second cylinder 54 flows further upward and is discharged from the top and periphery of the first cylinder 51. In this process, the water can form a vortex flow along the second blades 56 outside the third sleeve 55 and flow upward, and part of the water flow can be discharged from the diversion hole 52 of the first sleeve 51. It is easy to form an upward turbulent flow inside the second tube body 32, forming turbulence inside the second tube body 32 and the first protective cover 30, thereby improving the water flushing and cleaning effect and avoiding blockage of each hole. More importantly, when the ultraviolet lamp 33 is powered on, the turbulent flow formed inside the second tube body 32 and the first protective cover 30 can easily change the angle of ultraviolet irradiation, so as to increase the irradiation range and avoid blind spots. In addition, by arranging a diversion component 50 inside the second tube body 32, it is possible to prevent or reduce the entry of organisms into the second tube body 32 and the first protective cover 30, and the circulation of objects is restricted by the rubber plate 57, which also serves as an interception for mud and sand.

[0060] See attached Figure 6 As shown, a connecting ring 58 is coaxially fixed to the inner bottom of the first sleeve 51. A first curved rod 53 is connected to the connecting ring 58. The first curved rod 53 is arranged perpendicular to the axis of the connecting ring 58, and the two ends of the first curved rod 53 are bent and connected to the annular surface of the connecting ring 58. The structure of the connecting ring 58 and the first curved pipe 53 can divert water flow from the second cylinder 54 upward or from the interior of the first protective cover 30 downward, thereby reducing the possibility of water turbulence. In addition, the first curved pipe 53 acts as an interception and restriction, preventing or reducing the possibility of organisms and objects passing through.

[0061] See attached Figure 7As shown, the connecting rod 41 is hinged with two swing plates 42, and a spring 47 is provided between the swing plates 42. The swing plates 42 are preferably provided on the side of the connecting rod 41 away from the first blade 22. By providing the swing plates 42 on the connecting rod 41, it is possible to guide the water formed by the rotation of the first blade 22. Specifically, the water forms a vortex under the rotation of the first blade 22 and is discharged outward from the space between the connecting rods 41. In this process, the water can pass through the swing plates 42. The swing plates 42 between adjacent connecting rods 41 limit the water discharge space, thereby increasing the outward discharge flow rate of the water and improving the water flushing effect on the surface of the marine monitoring equipment. At the same time, according to the outward discharge flow rate of the water, the spring 47 can adjust the spacing between the swing plates 42 to control the water discharge channel space. In this process, the swing plates 42 continuously swing with the spring 47, which is easy to generate vibration, which helps to drive away organisms around the device and remove surface dirt. It also facilitates the transmission of vibration to the connecting rod 41, and then to the first base plate 40 and the second base plate 45 to drive away organisms attached to the upper part.

[0062] Elastic cords 43 are arranged around and connected between the first and second base plates 40, 45. These cords 43 are spaced apart between the connecting rods 41 and are provided with first baffles 44. These first baffles 44 are preferably smooth plates, such as metal sheets. The elastic cords 43 act to intercept and limit the passage between the connecting rods 41, preventing or reducing the ingress of fish and marine life into the space between the first and second base plates 40, 45. The first baffles 44 on the elastic cords 43 further restrict the area of the passage where organisms can enter. When the first blades 22 rotate, the resulting vortex displaces the first baffles 44 and deforms the elastic cords 43, releasing the first baffles 44 from restricting the fluid passage between the connecting rods 41. Furthermore, the change in position of the first baffles 44 during displacement helps alter the angle of the UV light emitted by the operating UV lamp 33, thereby increasing the irradiation range and avoiding blind spots.

[0063] A battery 10 is provided on the upper portion of the first motor 20 , and the battery 10 is electrically connected to the first motor 20 and / or the ultraviolet lamp 33 . The battery 10 is used to power the first motor 20 and the ultraviolet lamp 33 .

[0064] The first protective cover 30 is made of a light-transmitting material, such as quartz glass, and is used to irradiate the surrounding area with ultraviolet rays.

[0065] Preferably, the ultraviolet lamp 33 is intermittently turned on and off. The ultraviolet lamp 33 is continuously powered for 30 minutes to 60 minutes every 24 hours.

[0066] Example 2:

[0067] This embodiment is a further improvement based on embodiment 1: Figure 8 As shown, the upper and lower sections of the battery 10 are respectively provided with a first motor 20, and the first motors 20 provided at the upper and lower sections of the battery 10 are both provided with an output shaft 21 and the output shaft 21 are both provided with a first blade 22. The above design is used to improve the cyclone cleaning effect, wherein the first motor 20 provided at the upper part of the battery 10 drives the rotation of the output shaft 21 and the first blade 22 on the upper part thereof to drive the surrounding water flow to cyclone clean the first protective cover 30 and adjacent components.

[0068] Example 3:

[0069] This embodiment is a further improvement based on embodiment 1: Figure 9 As shown, a pressure-resistant cover 60 is provided on the upper part of the first substrate 40, and the battery 10, the first motor 20 and the first protective cover 31 are arranged in the pressure-resistant cover 60. When the first protective cover 30 is arranged in the pressure-resistant cover 60, the inlet end of the first tube body 31 is sealed.

[0070] Example 4:

[0071] This embodiment is a further improvement based on embodiment 1: Figure 10 As shown, the battery 10 is connected to the photovoltaic panel 70 via a connecting line 71, and the photovoltaic panel 70 supplies power to the battery 10, so that the device can work continuously for a long time.
