Description

Technical Field

[0001] This invention relates to the field of marine data monitoring equipment technology, specifically to a portable monitoring device for marine engineering and its operating method. Background Technology

[0002] Marine engineering involves multiple phases, including preliminary planning, design, mid-term construction, and post-construction operation. The required monitoring data covers multiple dimensions, including environment, structure, ecology, and disaster early warning. The preliminary planning phase of marine engineering requires the collection and analysis of meteorological, hydrological, water quality, and geological parameters.

[0003] Existing marine data monitoring equipment, such as wave buoys and weather stations, are all fixed structures requiring fixed-point installation, which is cumbersome, costly, and inflexible in relocation. Another type is ship-mounted marine data monitoring equipment, where the ship sequentially passes through navigational points for monitoring; this method is inefficient and consumes a lot of energy. Therefore, there is a need to design a portable monitoring device and operating method for marine engineering to solve the problems of high cost and low efficiency caused by the inflexible deployment and disassembly of existing marine data monitoring equipment. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a portable monitoring device and its working method for marine engineering.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a portable monitoring device for marine engineering, including an upper shell and a lower shell, the upper shell and the lower shell are sealed together, an attraction plate is provided on the top of the upper shell, a data acquisition main board and a battery are provided inside the upper shell, the data acquisition main board is connected to a data acquisition sensor group one and a data acquisition sensor group two, the data acquisition sensor group one collects air parameters, and the data acquisition sensor group two contacts seawater to collect seawater data.

[0006] The lower housing contains a main counterweight and a water storage chamber. The probe of the second sensor group extends into the water storage chamber. The bottom of the lower housing has a lower cover that supports the lifting assembly weight, which is connected to the bottom of the lower housing.

[0007] Specifically, an upper flange is provided on the bottom outer ring of the upper housing, and an upper flange is provided on the top outer ring of the lower housing. The upper flange and the lower flange are connected by bolts, and a sealing plate is clamped between the upper flange and the lower flange.

[0008] Specifically, the sealing plate is a fully sealed rubber plate, and the size of the sealing plate is larger than the size of the upper flange and the lower flange. The exposed part of the sealing plate forms a rolled edge with a downward hook structure.

[0009] Specifically, the sealing plate is provided with a second mounting hole, the height of which is greater than the thickness of the sealing plate. After applying sealant to the second mounting hole, the second sensor assembly is installed by pressing.

[0010] Specifically, the upper part of the upper housing is provided with a mounting hole 1, which is located below the suction plate. The mounting hole 1 is a threaded hole, and after applying sealant to the mounting hole 1, the outer shell of the data acquisition sensor group 1 is threadedly connected.

[0011] Specifically, both the first and second sensor groups are connected to the mainboard via communication lines. The mainboard is fixedly mounted inside the upper housing via a bracket. A battery is fixedly mounted on the bracket and supplies power to the mainboard. Cables connecting the battery to the outside are connected to a solar panel. The cables pass through cable through holes on the upper housing, and the solar panel is mounted on the outer wall of the upper housing.

[0012] Specifically, the water storage cavity adopts a box structure with an open top. The outer periphery of the water storage cavity is sealed and welded to the inner wall of the lower shell. A water inlet pipe is provided on one side of the water storage cavity, and a water inlet is provided at the corresponding position on the lower shell. After the water inlet is coated with sealant, the water inlet pipe passes through.

[0013] Specifically, a filling cavity is formed at the bottom of the lower shell, which is filled with polyethylene foam. A main counterweight is installed inside the filling cavity, and a gap is provided between the main counterweight and the inner wall of the lower shell. A lower cover connecting rope is installed on the lower outer wall of the lower shell, and the lower cover connecting rope is connected to the lower cover.

[0014] Specifically, a crossbeam is installed at the bottom of the lower housing, and a lifting ring is installed on the crossbeam. The lifting ring is connected to a lifting rope, and the lifting rope is connected to a lifting assembly weight. A protruding ring is provided at the bottom of the lower housing, and a groove is provided around the outer side of the protruding ring. A sealing ring is embedded in the groove. The sealing ring is made of water-soluble paper. A retaining ring is provided at the top of the lower cover. The retaining ring clamps the outer side of the protruding ring by squeezing the sealing ring. The lower cover is installed at the bottom of the lower housing.

[0015] A method for operating a portable monitoring device for marine engineering includes the following steps:

[0016] S1. Check the sealing of the upper and lower housings and the integrity of the equipment. Replace the sealing rings with new ones. Retract the hoisted assembly into the lower cover and secure the lower cover tightly.

[0017] S2. The bottom of the drone is equipped with a release lever and an electromagnet. When the electromagnet is energized, it attracts the attraction plate on the top of the shell. The drone is controlled to reach the predetermined position. When the electromagnet is de-energized, it releases the attraction plate, and the monitoring device falls to the water surface. Based on the roly-poly shape and bottom counterweight, the monitoring device floats upright on the water surface.

[0018] S3. Seawater enters the connection between the lower cover and the lower shell. The water-soluble paper-type sealing ring dissolves in water. The lower cover opens under the gravity of the hoisting assembly weight. The lower cover is pulled by the lower cover connecting rope. The hoisting assembly weight sinks into the water and is pulled by the hoisting rope. Under the action of the main counterweight and the hoisting assembly weight, the waterline of the monitoring device reaches the bottom of the rolled edge of the sealing plate.

[0019] S4. During the swaying and floating process of the monitoring device, seawater enters the water storage chamber through the water inlet pipe, and the seawater in the water storage chamber comes into contact with the probe of the second sensor group.

[0020] S5. The mainboard collects and stores the data collected by sensor group one and sensor group two, and uploads it to the data monitoring platform via the wireless module.

[0021] S6. A Beidou positioning module is set on the mainboard. When the monitoring device needs to be retrieved, the UAV identifies the location of the monitoring device through the Beidou positioning module, and uses an electromagnet to attract the suction plate to hoist the monitoring device back.

[0022] The present invention has the following beneficial effects:

[0023] This invention relates to a portable marine engineering monitoring device and its operating method. It employs a compact, integrated structural design and utilizes a drone for multi-point distributed deployment, resulting in higher data collection density and accuracy. The self-sustaining shell design, combined with counterweights, enhances stability, preventing the device from easily tipping over in wind and waves. The addition of lifting counterweights further stabilizes the device. A seawater-introducing structure protects the probe, preventing damage and improving monitoring accuracy.

[0032] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1-5 As shown, a portable monitoring device for marine engineering includes an upper shell 1 and a lower shell 2, which are sealed together. The top of the upper shell 1 is provided with an attraction plate 1.1, which is made of a magnetic metal plate and is easily attracted by an electromagnet extending from the bottom of the UAV.

[0034] The upper housing 1 has an upper flange 1.10 on the bottom outer ring and the lower housing 2 has an upper flange 2.12 on the top outer ring. The upper flange 1.10 and the lower flange 2.12 are connected by bolts, and a sealing plate 3 is sandwiched between the upper flange 1.10 and the lower flange 2.12.

[0035] The sealing plate 3 is a fully sealed rubber plate, which isolates the upper shell 1 and the lower shell 2. The size of the sealing plate 3 is larger than the size of the upper flange 1.10 and the lower flange 2.12. The exposed part of the sealing plate 3 forms a rolled edge 3.1 with a downward hook structure. The rolled edge 3.1 can not only protect the water inlet 2.10, but also provide stable support for the overall equipment to float on the water surface.

[0036] The upper housing 1 houses a data acquisition motherboard 1.4 and a battery 1.5. The data acquisition motherboard 1.4 uses an STM32 series control board and integrates a storage module, a wireless transmission module, and a Beidou positioning module. The motherboard 1.4 communicates and transmits data to the data monitoring platform via the wireless transmission module. The motherboard 1.4 connects to two sensor groups: Sensor Group 1.7 and Sensor Group 2.9. Sensor Group 1.7 includes, as needed, temperature and humidity sensors, light sensors, and barometers, integrating all probes into a cylindrical mounting box. Sensor Group 1.7 collects multiple air parameters. Sensor Group 2.9 uses temperature sensors, salinity sensors, and water quality sensors, integrating all probes into a cylindrical mounting box. Sensor Group 2.9 collects seawater data.

[0037] The upper part of the upper housing 1 is provided with a mounting hole 1.6, which is located below the suction plate 1.1. The mounting hole 1.6 is a threaded hole. After applying sealant to the mounting hole 1.6, the cylindrical outer shell of the acquisition sensor group 1.7 is threadedly connected.

[0038] The lower housing 2 is equipped with a main counterweight 2.1 and a water storage chamber 2.11. The probe of the second sensor group 1.9 extends into the water storage chamber 2.11. The sealing plate 3 is equipped with a second mounting hole 1.8. The height of the second mounting hole 1.8 is greater than the thickness of the sealing plate 3. That is, a rubber cylinder with protrusions at both the top and bottom is set on the sealing plate 3. After applying sealant to the second mounting hole 1.8, the second sensor group 1.9 is squeezed and installed to form a seal, preventing seawater from entering the upper housing 1 through the second mounting hole 1.8.

[0039] Both sensor group 1.7 and sensor group 2.9 are connected to the acquisition motherboard 1.4 via communication lines. The acquisition motherboard 1.4 is fixedly installed inside the upper housing 1.1 via bracket 1.3. A storage battery 1.5 is fixedly installed on the bracket 1.3. The storage battery 1.5 is connected to and supplies power to the acquisition motherboard 1.4. The storage battery 1.5 is connected to an external cable that connects to the solar panel 1.2. The cable passes through the cable through hole on the upper housing 1.1. The solar panel 1.2 is installed on the outer wall of the upper housing 1.

[0040] The water storage chamber 2.11 adopts a box structure with an open top. The outer periphery of the water storage chamber 2.11 is sealed and welded to the inner wall of the lower shell 2. A water inlet pipe is provided on one side of the water storage chamber 2.11, and a water inlet 2.10 is provided at the corresponding position on the lower shell 2. After the water inlet 2.10 is coated with sealant, the water inlet pipe passes through it. Seawater enters the water storage chamber 2.11 only through the water inlet and will not communicate with the seawater in the lower part of the lower shell 2, thereby improving the cleanliness of the seawater in the water storage chamber 2.11. The seawater in the lower part of the lower shell 2 floats up by filling with floating materials.

[0041] The bottom of the lower housing 2 is provided with a lower cover 2.3, which supports the lifting assembly weight 2.4. The lifting assembly weight 2.4 is connected to the bottom of the lower housing 2.

[0042] The bottom of the lower shell 2 forms a filling cavity 2.2, which is filled with polyethylene foam. The main counterweight 2.1 is installed in the filling cavity 2.2. There is a gap between the main counterweight 2.1 and the inner wall of the lower shell 2, allowing seawater to come into contact with the polyethylene foam. The lower cover connecting rope 2.9 is installed on the lower outer wall of the lower shell 2, and the lower cover connecting rope 2.9 is connected to the lower cover 2.3.

[0043] A crossbeam is installed at the bottom of the lower housing 2, and a lifting ring is installed on the crossbeam. The lifting ring is connected to a lifting rope 2.5, and the lifting rope 2.5 is connected to a lifting counterweight 2.4. The bottom of the lower housing 2 has a protruding ring 2.6, and a groove is provided around the outer side of the protruding ring 2.6. The groove is embedded with a sealing ring 2.8, which is made of water-soluble paper. A retaining ring 2.7 is provided on the upper part of the lower cover 2.3. The retaining ring 2.7 clamps the outer side of the protruding ring 2.6 by squeezing the sealing ring 2.8. The lower cover 2.3 is installed at the bottom of the lower housing 2.

[0044] A method for operating a portable monitoring device for marine engineering includes the following steps:

[0045] 1. Check the sealing of the upper housing 1 and the lower housing 2 and the integrity of the equipment. Replace the new sealing ring 2.8. Put the hoisting counterweight 2.4 back into the lower cover 2.3 and fix the lower cover 2.3 tightly.

[0046] 2. The bottom of the drone is equipped with a release lever and an electromagnet. When the electromagnet is energized, it attracts the attraction plate 1.1 on the top of the upper shell 1. When the drone is controlled to reach the predetermined position, the electromagnet is de-energized and releases the attraction plate 1.1. The monitoring device falls to the water surface. Due to the roly-poly shape and bottom counterweight, the monitoring device floats upright on the water surface.

[0047] 3. Seawater enters the connection between the lower cover 2.3 and the lower shell 2. The water-soluble paper-type sealing ring 2.8 dissolves in water. The lower cover 2.3 opens under the gravity of the lifting assembly weight 2.4. The lower cover 2.3 is pulled by the lower cover connecting rope 2.9. The lifting assembly weight 2.4 sinks into the water and is pulled by the lifting rope 2.5. Under the action of the main counterweight 2.1 and the lifting assembly weight 2.4, the waterline of the monitoring device reaches the bottom of the rolled edge part 3.1 of the sealing plate 3.

[0048] 4. During the swaying and floating process of the monitoring device, seawater enters the water storage chamber 2.11 through the water inlet pipe, and the seawater in the water storage chamber 2.11 comes into contact with the probe of the second sensor group 1.9.

[0049] 5. The mainboard 1.4 collects and stores the data collected by sensor group one 1.7 and sensor group two 1.9, and uploads it to the data monitoring platform via a wireless module.

[0050] 6. A Beidou positioning module is set on the mainboard 1.4. When the monitoring device needs to be retrieved, the UAV identifies the location of the monitoring device through the Beidou positioning module, and uses an electromagnet to attract the suction plate 1.1 to hoist the monitoring device back.

[0051] This invention is not limited to the above-described embodiments. Anyone should know that any structural changes made under the guidance of this invention, and any technical solutions that are the same as or similar to this invention, fall within the protection scope of this invention.
