Description

Technical Field

[0001] The present invention relates to the technical field of ocean monitoring, and in particular to an ocean monitoring device based on buoyancy adjustment delay. Background Art

[0002] Ocean environmental monitoring acts on the protection of the marine ecosystem, mainly including the monitoring of ocean environmental elements and ocean chemical elements. The monitoring of ocean environmental elements mainly includes observations such as water depth, water temperature, salinity, ocean current, wave, water color, transparency, sea ice, and sea glow. The monitoring of ocean chemical elements mainly includes dissolved oxygen, total alkalinity, reactive silicate, reactive phosphate, nitrate, nitrite, total phosphorus, total nitrogen, and total carbon.

[0003] Ocean observation instruments refer to the general term for equipment used for ocean observation, sampling, testing, etc. Usually classified according to marine science specialties, they are divided into ocean physical instruments, ocean chemical instruments, ocean biological instruments, and ocean geological and geophysical observation instruments, etc. At present, the acquisition of ocean parameters mainly relies on buoys or moored buoys placed on the sea surface. The ocean parameters obtained by these two methods are limited. Buoys mainly collect hydrological parameters on the water surface and nearby, and it is difficult to obtain large-depth longitudinal profile ocean parameters. Some buoys, through improved design, use high-pressure piston pumps to suck and discharge liquids, causing changes in their own displacement and generating the power for floating and sinking. The sensors carried by the floating buoys moving up and down are used for profile observation.

[0004] Based on the ocean observation instruments in the prior art, when detecting the ocean, under the action of the self-gravity of the monitoring device and the gravity of seawater, the monitoring device will quickly fall in the ocean, resulting in the sensor being unable to detect seawater in a timely manner, causing deviations in the monitoring data and low practicability. Summary of the Invention

[0005] The purpose of the present invention is to provide an ocean monitoring device based on buoyancy adjustment delay, which can adjust the overall buoyancy of the device according to the depth and external pressure, so that the whole device slowly descends in seawater, preventing the whole device from descending too fast and causing the sensor to be unable to continuously monitor seawater, avoiding deviations in the monitoring data, and improving practicability.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] An ocean monitoring device based on buoyancy adjustment delay, characterized in that it includes a housing, a jacking mechanism, a flipping assembly, a magnet, an adjustment mechanism, and a detection mechanism.

[0008] The housing includes a shell and a mounting plate. The mounting plate is fixedly provided on the inner wall of the middle part of the shell. Four jacking mechanisms are provided inside the shell. A flipping assembly and four magnets are provided on the top of the shell. A number of adjusting mechanisms are provided on the periphery of the shell. A detecting mechanism is provided on the upper part of the shell.

[0009] Further, a water inlet is opened on the inner wall of the bottom of the shell, and a first pressure relief valve is screwed through the outer wall at the center of the top of the mounting plate.

[0010] Further, the jacking mechanism includes a connecting pipe, a mounting cylinder, a piston, a top rod, a return spring and a drain pipe.

[0011] The connecting pipe is disposed through the inside of the shell. The upper part of the connecting pipe is fixedly provided on the outer wall of the top of the mounting plate. The lower part of the connecting pipe is fixedly provided on the outer wall of the bottom of the shell. The mounting cylinder is fixedly provided on the outer wall of the upper part of the connecting pipe. The bottom of the mounting cylinder abuts against the outer wall of the top of the mounting plate. The return spring is sleeved inside the mounting cylinder.

[0012] The piston is slidably mounted inside the mounting cylinder. A sealing ring is fixedly provided on the outer wall of the piston. The bottom of the top rod is fixedly provided on the outer wall of the top of the piston. The upper part of the top rod penetrates and is slidably sleeved on the outer wall of the top of the shell. Four through holes with inner diameters adapted to the outer diameter of the top rod are opened on the inner wall of the top of the shell.

[0013] Further, the flipping assembly includes a mounting block, four buoyancy plates and a limiting block.

[0014] The mounting block is fixedly provided on the outer wall of the top of the shell. Two buoyancy plates are respectively hinged on both sides of the mounting block. The other two buoyancy plates are respectively hinged on the outer walls of both sides of the mounting block. The limiting block is fixedly provided on the outer wall of the top of the mounting block.

[0015] Further, four mounting grooves are opened on the outer wall of the upper part of the shell, and the four magnets are respectively fixedly provided in the four mounting grooves.

[0016] Further, the adjusting mechanism includes two mounting plates, a reaction cylinder, a connecting pipe, a gas collecting hood and a rubber pipe.

[0017] The two mounting plates are respectively fixedly provided on the outer wall of the shell. The reaction cylinder is fixedly provided on the outer wall of the lower part of the two mounting plates. The gas collecting hood is fixedly provided on the outer wall of the upper part of the two mounting plates. The rubber pipe is fixedly provided on the outer wall of the top of the reaction cylinder.

[0018] One end of the connecting pipe is fixedly arranged on the upper inner wall of the reaction cylinder, and the other end of the connecting pipe passes through and is fixedly arranged on the inner wall of the middle part of the shell below the mounting plate. A second pressure relief valve is clamped and installed on the outer wall of the other end of the connecting pipe.

[0019] Furthermore, air holes are provided on the top outer wall of the reaction cylinder and the bottom outer wall of the gas collecting hood.

[0022] Furthermore, the interior of the reaction cylinder is filled with calcium carbide powder.

[0023] Beneficial effects of the present invention:

[0024] Seawater enters the connecting pipe. As the device as a whole descends in the seawater, the seawater pressure in the connecting pipe increases synchronously with the seawater pressure outside the device, so that the seawater in the connecting pipe squeezes the piston, and the reset spring squeezes the piston and offsets the seawater pressure. When the seawater pressure is greater than the tension of the reset spring, the piston drives the push rod to rise, and the push rod lifts the buoyancy plate, so that the buoyancy plate flips along the hinge on the mounting block, and the limit block limits the buoyancy plate, so that the contact area between the device as a whole and the seawater is increased, thereby increasing the buoyancy of the device as a whole. Seawater enters the shell. When the pressure inside the shell is greater than the set pressure value of the second pressure relief valve, seawater enters the reaction cylinder along the connecting pipe. The seawater reacts with the calcium carbide in the reaction cylinder to produce a large amount of gas. The gas causes the rubber tube to expand, further increasing the buoyancy of the device as a whole. The buoyancy of the device as a whole can be adjusted according to the depth and external pressure, so that the device as a whole slowly descends in the seawater, preventing the device as a whole from descending too fast, causing the sensor to be unable to continuously monitor the seawater, avoiding deviations in the monitoring data, and improving practicality.

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention.

[0039] As Figures 1 - 4 shown, a marine monitoring device based on buoyancy adjustment and time delay includes an outer shell 1, a jacking mechanism 2, a flipping assembly 3, a magnet 4, an adjusting mechanism 5 and a detection mechanism 6.

[0040] The housing 1 includes a housing body 101 and a mounting plate 102. The mounting plate 102 is fixedly provided on the inner wall of the middle part of the housing body 101. Four jacking mechanisms 2 are provided inside the housing body 101. A flipping assembly 3 and four magnets 4 are provided at the top of the housing body 101. A number of adjusting mechanisms 5 are provided on the periphery of the housing body 101. A detecting mechanism 6 is provided at the upper part of the housing body 101.

[0041] As a preferred embodiment of the present invention, a water inlet is provided on the inner wall of the bottom of the housing body 101, and a first pressure relief valve 103 is screwed through the outer wall at the center of the top of the mounting plate 102.

[0042] As a preferred embodiment of the present invention, as Figure 5 shown, the jacking mechanism 2 includes a connecting pipe 201, a mounting cylinder 202, a piston 203, a push rod 204, a return spring 205 and a drain pipe 206. Seawater enters the connecting pipe 201. As the whole device descends in the seawater, the seawater pressure in the connecting pipe 201 increases synchronously with the seawater pressure outside the device, so that the seawater in the connecting pipe 201 squeezes the piston 203, and the return spring 205 squeezes the piston and offsets the seawater pressure.

[0043] As Figure 2 and Figure 5 shown, the connecting pipe 201 is disposed through the inside of the housing body 101. The upper part of the connecting pipe 201 is fixedly provided on the outer wall of the top of the mounting plate 102. The lower part of the connecting pipe 201 is fixedly provided on the outer wall of the bottom of the housing body 101. The mounting cylinder 202 is fixedly provided on the outer wall of the upper part of the connecting pipe 201. The bottom of the mounting cylinder 202 abuts against the outer wall of the top of the mounting plate 102. The return spring 205 is sleeved inside the mounting cylinder 202.

[0044] The piston 203 is slidably mounted inside the mounting cylinder 202. A sealing ring is fixedly provided on the outer wall of the piston 203. The bottom of the push rod 204 is fixedly provided on the outer wall of the top of the piston 203. The upper part of the push rod 204 penetrates and is slidably sleeved on the outer wall of the top of the housing body 101. Four through holes with an inner diameter size adapted to the outer diameter size of the push rod 204 are provided on the inner wall of the top of the housing body 101.

[0045] As a preferred embodiment of the present invention, as Figure 6 shown, the flipping assembly 3 includes a mounting block 301, four buoyancy plates 302 and a limiting block 303. When the seawater pressure is greater than the tension of the return spring 205, the piston 203 drives the push rod 204 to rise. The push rod 204 jacks up the buoyancy plates 302, so that the buoyancy plates 302 flip along the hinge on the mounting block 301. The limiting block 303 limits the buoyancy plates 302, so that the contact area between the whole device and the seawater increases, thereby increasing the buoyancy of the whole device.

[0046] As shown in Figure 1 and Figure 6 shown, the mounting block 301 is fixedly arranged on the outer wall of the top of the housing 101, two buoyancy plates 302 are respectively hinged to both sides of the mounting block 301, and the other two buoyancy plates 302 are respectively hinged to the outer walls of both sides of the mounting block 301. The limiting block 303 is fixedly arranged on the outer wall of the top of the mounting block 301.

[0047] As a preferred embodiment of the present invention, as shown in Figures 1 - 3 shown, four mounting grooves are formed on the outer wall of the upper part of the housing 101, and the four magnets 4 are respectively fixedly arranged in the four mounting grooves.

[0048] As a preferred embodiment of the present invention, as shown in Figure 7 shown, the adjusting mechanism 5 includes two mounting plates 501, a reaction cylinder 502, a connecting pipe 503, a gas collecting hood 504 and a rubber pipe 505.

[0049] As shown in Figure 1 , Figure 2 and Figure 7 shown, the two mounting plates 501 are respectively fixedly arranged on the outer wall of the housing 101, the reaction cylinder 502 is fixedly arranged on the outer wall of the lower part of the two mounting plates 501, the gas collecting hood 504 is fixedly arranged on the outer wall of the upper part of the two mounting plates 501, and the rubber pipe 505 is fixedly arranged on the outer wall of the top of the reaction cylinder 502.

[0050] One end of the connecting pipe 503 is fixedly arranged on the inner wall of the upper part of the reaction cylinder 502, the other end of the connecting pipe 503 penetrates and is fixedly arranged on the inner wall of the middle part of the housing 101 below the mounting plate 102. A second pressure relief valve is installed on the outer wall of the other end of the connecting pipe 503. When seawater enters the interior of the housing 101 and the pressure inside the housing 101 is greater than the set pressure value of the second pressure relief valve, the seawater enters the reaction cylinder 502 along the connecting pipe 503. The seawater reacts with calcium carbide in the reaction cylinder 502 to generate a large amount of gas, and the gas causes the rubber pipe 505 to expand, further increasing the buoyancy of the whole device.

[0051] As a preferred embodiment of the present invention, air holes are formed on both the outer wall of the top of the reaction cylinder 502 and the outer wall of the bottom of the gas collecting hood 504.

[0052] As a preferred embodiment of the present invention, as shown in Figure 4 shown, the detection mechanism 6 includes a mounting box 601, a storage battery 602 and a sensor probe 603.

[0053] As shown in Figure 1 , Figure 2 and Figure 4As shown in the figure, the installation box 601 is fixedly arranged on the inner wall of the upper part of the housing 101. A storage battery 602 is connected to the bottom inner wall of the installation box 601 by bolts. The sensor probe 603 is fixedly arranged through the top inner wall of the housing 101. The sensor probe 603 is used to detect the ocean data at the depth where the current device is located.

[0054] As a preferred embodiment of the present invention, the reaction cylinder 502 is filled with calcium carbide powder. When calcium carbide reacts with water, acetylene and calcium hydroxide are generated. The reaction between calcium carbide and water is very violent and releases a large amount of heat. At the same time, the seawater around the device absorbs the heat generated during the reaction to prevent the device from being damaged by the heat.

[0055] The working principle of the present invention:

[0056] Seawater enters the communicating pipe 201. As the whole device descends in the seawater, the seawater pressure in the communicating pipe 201 increases synchronously with the seawater pressure outside the device, causing the seawater in the communicating pipe 201 to squeeze the piston 203. The return spring 205 squeezes the piston to offset the seawater pressure. When the seawater pressure is greater than the tension of the return spring 205, the piston 203 drives the ejector rod 204 to rise. The ejector rod 204 jacks up the buoyancy plate 302, causing the buoyancy plate 302 to flip along the hinge on the mounting block 301. The limit block 303 limits the buoyancy plate 302, increasing the contact area between the whole device and the seawater, thereby increasing the buoyancy of the whole device. Seawater enters the housing 101. When the pressure inside the housing 101 is greater than the set pressure value of the second pressure relief valve, the seawater enters the reaction cylinder 502 along the connecting pipe 503. The seawater reacts with the calcium carbide in the reaction cylinder 502 to generate a large amount of gas, which causes the rubber tube 505 to expand, further increasing the buoyancy of the whole device.

[0057] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Those skilled in the art can still adjust the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Therefore, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention also intends to include these modifications and variations.
