Description

Technical Field

[0001] This invention belongs to the field of crab farming technology, specifically relating to a self-oxygenation system for crab farming based on Internet of Things (IoT) monitoring. Background Technology

[0002] In order to ensure the normal growth and health of crabs, an oxygenation system is needed to supplement the water in the crab farming area to ensure that the dissolved oxygen content in the water is sufficient.

[0003] An oxygenation system typically includes an oxygenation pump, which is connected to an oxygen outlet via an air delivery pipe. When the oxygen outlet is in the water, oxygen is supplied to the oxygen outlet by the oxygenation pump and then introduced into the water through the oxygen outlet, thus completing the oxygenation process.

[0004] In order to ensure the effectiveness of oxygen supplementation, the oxygen outlet location is usually adjusted according to the distribution of crabs and the water conditions to form different oxygenation schemes, thereby better supplementing oxygen in the water in the crab farming area.

[0005] When adjusting the oxygen outlet position, a gas delivery tube is required. The gas delivery tube is usually a flexible hose or an adjustable steel pipe combination. If the gas delivery tube is an adjustable steel pipe combination, although the adjustable steel pipe combination is suitable for matching the position of the oxygen outlet head, the adjustment range of the steel pipe combination is limited, which greatly restricts the adjustment range of the oxygen outlet head position.

[0006] If the air delivery tube is a flexible tube, although the flexible tube can adapt to the movement of the oxygen outlet head through its own deformation, reducing the limitation on the adjustment range of the oxygen outlet head position, during use, crabs in the water are likely to come into contact with the flexible tube. When the crabs clamp the flexible tube, it is easy to cause clamping damage to the crabs. Summary of the Invention

[0007] The purpose of this invention is to provide a self-oxygenating system for crab farming based on Internet of Things (IoT) monitoring. This system can remotely monitor the oxygen content in crab farming waters and adjust various oxygenation schemes. Furthermore, it can use temperature changes to drive away crabs during oxygenation, effectively reducing the damage caused by crabs clamping onto the air delivery hose.

[0008] The specific technical solution adopted by this invention is as follows:

[0009] An IoT-based self-oxygenation system for crab farming includes a self-oxygenation device and a control terminal connected by a signal.

[0010] The self-oxygenating device includes:

[0011] Support structure;

[0012] A buoyancy component installed on the support body is used to provide buoyancy to the support body;

[0013] An oxygenation module, comprising an oxygenation pump mounted on a support body and an electrically adjustable bracket mounted on a buoyancy component, wherein an air outlet is mounted on the electrically adjustable bracket, and the air outlet and the oxygenation pump are connected by an air guide hose, and a temperature change layer is provided on the outside of the air guide hose.

[0014] Dissolved oxygen sensor, used to measure the oxygen content in water;

[0015] The intelligent control module is installed on the support body. The oxygen pump, the electric adjustment bracket and the dissolved oxygen sensor are all electrically connected to the intelligent control module. The intelligent control module is also signal-connected to the control terminal.

[0016] The power module is installed on the buoyancy component, and the oxygenation pump, electric adjustment bracket, and control host are all electrically connected to the power module.

[0017] Furthermore, the air delivery hose includes a flexible inner tube, one end of which is fixedly connected to an oxygenation pump, and the other end of which is fixedly connected to an air outlet. An outer tube body is provided on the outside of the flexible inner tube, and a heating device electrically connected to the intelligent control module is installed inside the outer tube body.

[0018] Furthermore, the outer tube is also equipped with a pressure triggering mechanism that is electrically connected to the intelligent control module.

[0019] Furthermore, the heating device includes an electrically connected heater and multiple heating elements, which are connected in parallel via electrical wires. The heater is mounted on a buoyancy member, and the multiple heating elements are mounted inside the outer tube.

[0020] Furthermore, flexible heat-conducting plates are installed on both the outer tube and the heating element, and flexible heat dissipation plates are installed on the inner wall of the flexible inner tube. The flexible heat dissipation plates and the flexible heat-conducting plates are connected by heat-conducting wires.

[0021] Furthermore, an annular space is formed between the outer tube and the flexible inner tube, which is wrapped around the outside of the flexible inner tube. The annular space contains a flowing medium, and the pressure triggering mechanism is used to monitor the pressure of the flowing medium inside the annular space.

[0022] Furthermore, the flowing medium is brine.

[0023] Furthermore, the pressure triggering mechanism is a pressure sensor installed on the outer tube body, and the number of pressure sensors is at least one.

[0024] Furthermore, the power module includes a solar panel and a battery mounted on a support, and the solar panel and the battery are electrically connected.

[0025] Furthermore, the control terminal is an APP installed on a smart device.

[0027] (1) The crab farming self-oxygenation system based on Internet of Things monitoring of the present invention can remotely monitor and supplement oxygen in crab farming waters through the structure of control terminal and self-oxygenation equipment. When supplementing oxygen, the position of the oxygen outlet can be freely adjusted according to the user's needs by setting the electric adjustment bracket and the air outlet, and various oxygenation schemes can be adjusted. Furthermore, by setting a temperature change layer on the outside of the air guide hose, the temperature change can be used to drive away the crabs, so that the crabs are away from the air guide hose, effectively reducing the damage caused by the crabs clamping the air guide hose.

[0037] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0038] like Figure 1-7 As shown, a self-oxygenation system for crab farming based on Internet of Things monitoring includes a self-oxygenation device 17 and a control terminal 16 connected by a signal. The control terminal 16 can operate the self-oxygenation device 17.

[0039] The self-oxygenating device 17 includes a support body 2, a buoyancy component 1, an oxygenation module, a dissolved oxygen sensor, an intelligent control module, and a power supply module.

[0040] Among them, the support body 2 serves as the main body of the self-oxygenating device 17 and is the supporting structure for the other modules;

[0041] The buoyancy component 1 is installed on the support body 2, and the support body 2 is preferably installed on the lower side of the support body 2 to provide buoyancy for the support body 2. The buoyancy component 1 and the support body 2 can be an integral structure, that is, it can serve as a support for the other modules and also has buoyancy. The buoyancy component 1 can be an airbag, a hollow box or a buoyancy plate, preferably a hollow plastic box.

[0042] The oxygenation module includes an oxygenation pump 5 mounted on the support body 2 and an electrically adjustable support 6 mounted on the buoyancy component 1. The electrically adjustable support 6 can be a multi-degree-of-freedom robotic arm, a submersible robot that can move underwater, or other electrically adjustable equipment. An air outlet 7 is installed on the electrically adjustable support 6, and the air outlet 7 and the oxygenation pump 5 are connected by an air guide hose 8. At this time, the position of the air outlet 7 can be freely adjusted by controlling the control terminal 16, so that the adjustment of the position of the air outlet 7 is less restricted, and the air guide hose 8 has less restriction on the air outlet 7 during the adjustment process, which can support the free adjustment of the air outlet 7.

[0043] To reduce the restriction on the air outlet 7 caused by the air guide hose 8 during the adjustment of the air outlet 7, the air outlet 7 is made of a flexible material that can be bent freely. In addition, to reduce the damage caused by the crab to the air guide hose 8 during operation, this technical solution improves the air guide hose 8. Specifically, a temperature changing layer is provided on the outside of the air guide hose 8, which can quickly change the temperature, making the crab feel uncomfortable and causing it to move away from the air guide hose 8, thereby effectively reducing the damage caused by the crab to the air guide hose 8.

[0044] like Figure 2-4As shown, the air delivery hose 8 includes a flexible inner tube 9. One end of the flexible inner tube 9 is fixedly connected to the oxygen pump 5, and the other end of the flexible inner tube 9 is fixedly connected to the air outlet 7, thereby enabling the oxygen output by the oxygen pump 5 to be transmitted to the air outlet 7. The surface of the air outlet 7 is provided with multiple openings, allowing the oxygen inside the air outlet 7 to be transmitted to the water. An outer tube body 10 is provided on the outside of the flexible inner tube 9. A heating device electrically connected to the intelligent control module is installed inside the outer tube body 10, which can rapidly heat the outer tube body 10. The combination of the outer tube body 10 and the heating device forms a temperature change layer. After heating is completed, the heating device is stopped. Through the flow of oxygen inside the flexible inner tube 9, heat dissipation from the outer tube body 10 can be quickly completed, thereby achieving rapid temperature changes and causing discomfort to the crabs.

[0045] Here, the flexible inner tube 9 and the outer tube body 10 can be made of any one of rubber, silicone, or polyurethane (PU).

[0046] Specifically, such as Figure 2 and Figure 5-6 As shown, the heating device includes an electrically connected heater 14 and multiple heating elements 12. The heater 14 and multiple heating elements 12 are preferably connected in parallel through a wire body 15, which can turn on the corresponding heating element 12 individually. At the same time, a circuit breaker can be installed on the wire body 15 to protect the heater 14.

[0047] The heater 14 is installed on the buoyancy member 1, and multiple heating elements 12 are installed inside the outer tube 10. The multiple heating elements 12 are preferably arranged in sequence from the end closest to the air outlet 7 to the end furthest from the air outlet 7. The heater 14 and the multiple heating elements 12 are preferably arranged in parallel so that the heating elements 12 can freely heat individual areas on the outer tube 10 as needed, thereby reducing power consumption.

[0048] Here, the heating element 12 can be any one of the following: resistance metal wire, silicone heating sheet, polyester heating sheet, and aluminum foil heating sheet. It is preferably a silicone heating sheet, which has the effects of good flexibility, high temperature resistance, waterproofness, and good insulation performance. Its typical working temperature range is -60℃ to 200℃, which can well meet the usage requirements of the heating element 12.

[0049] like Figure 7As shown, in order to improve the rapid cooling of the heating element 12 and the outer tube 10, flexible heat-conducting plates can be installed on both the outer tube 10 and the heating element 12. Flexible heat sinks 18 can be installed on the inner wall of the flexible inner tube 9. The flexible heat sinks 18 and the flexible heat-conducting plates are connected by heat-conducting wires. Both the flexible heat sinks 18 and the flexible heat-conducting plates can be any one of silicone grease heat-conducting plates, metal foil heat-conducting plates, and carbon fiber heat-conducting plates. Preferably, metal foil heat-conducting plates are preferred because they have excellent thermal conductivity and good flexibility. They can meet the deformation requirements of the flexible inner tube 9 and the outer tube 10 while having a good thermal conductivity effect, so that the heat energy on the outer tube 10 and the heating element 12 can be quickly transferred to the interior of the flexible inner tube 9. The cooling is achieved by the rapidly flowing oxygen inside the flexible inner tube 9, which greatly improves the cooling efficiency while reducing the increase in cost.

[0050] Furthermore, in order to further reduce energy consumption, the outer tube 10 is equipped with a pressure triggering mechanism that is electrically connected to the intelligent control module. When the crab clamps the outer tube 10, the pressure triggering mechanism detects the pressure change on the surface of the outer tube 10 and automatically generates a start signal, causing the intelligent control module to automatically start the heating equipment. The intelligent control module is equipped with a time relay or other timing module, which can turn off the heating equipment after heating for a specific period of time.

[0051] like Figure 3-5 As shown, in order to improve the detection range of the pressure triggering mechanism, an annular space 11 is formed between the outer tube 10 and the flexible inner tube 9, which is wrapped around the outside of the flexible inner tube 9. The annular space 11 contains a flowing medium, which can be a liquid or a gas, preferably salt water. The pressure triggering mechanism is used to monitor the pressure of the flowing medium inside the annular space 11. When the outer tube 10 is clamped, it will deform in the direction closer to the flexible inner tube 9, thereby pressurizing the flowing medium inside the annular space 11 and increasing the pressure of the flowing medium, so that the pressure triggering mechanism can detect the phenomenon of the outer tube 10 being clamped.

[0052] When the outer tube 10 is damaged, the brine inside the outer tube 10 is discharged through the rupture. At the same time, the pressure triggering mechanism can detect the damage to the outer tube 10 by the decrease in pressure and feed back to the control terminal 16 to remind the user to carry out maintenance. At this time, by using the irritant properties of the brine to drive away the crabs around, it can prevent the crabs from further damaging the flexible inner tube 9 for a certain period of time, thereby reducing the adverse effects caused by the breakage of the flexible inner tube 9 during the supply process.

[0053] The pressure triggering mechanism can be a pressure sensor 13 installed on the outer tube 10, and the number of pressure sensors 13 is at least one.

[0054] When there is only one pressure sensor 13, it can effectively monitor the pressure changes inside the annular space 11 and complete the self-starting process.

[0055] When there are two pressure sensors 13, the two pressure sensors 13 monitor the pressure of the flowing medium at both ends of the annular space 11 respectively. When a certain position of the outer tube 10 is squeezed, a pressure change will occur at that position. This pressure change will propagate to both ends of the annular space 11 in the form of waves in the water. Since the distance from the squeezing point to the two ends is different, the pressure change amplitude recorded by the pressure sensor 13 will be different. Based on this difference, the position of the squeezing point can be inferred.

[0056] To illustrate this more clearly, one of the testing methods is disclosed, and the testing steps are as follows:

[0057] S1. Pressure change measurement: Pressure sensors 13 are installed at both ends of the annular space 11 to record the magnitude of the pressure change, denoted as P1 and P2 respectively.

[0058] S2. Determine the attenuation model of the pressure wave: Assume that the attenuation of the pressure wave in water is known and can be expressed as:

[0059]

[0060] in, P It is a pressure wave at a certain distance d Pressure range at the location, P 0 It is the initial pressure amplitude. α It is the attenuation coefficient. e It is the base of the natural logarithm, approximately equal to 2.71828. Under this model, the pressure amplitude... P It will change with distance d It decreases exponentially with the increase of;

[0061] S3. Establish equations: The distances from the extrusion point to the two pressure sensors 13 are respectively d 2 and d 2 ,have:

[0062]

[0063] Since the total length of the annular space 11 is L ,so d 2 +d 2 =L ;

[0064] S4. Calculate the location of the extrusion point: From the above equation, we can obtain:

[0065]

[0066] Taking the logarithm, we get:

[0067]

[0068] Combination d 1 + d 2 = L Solve d 2 and d 2 :

[0069]

[0070] Solving these two equations yields d 1 and d 2 :

[0071] .

[0072] When there are multiple pressure sensors 13, the multiple pressure sensors 13 are arranged at equal intervals along the axis of the annular space 11. Each pressure sensor 13 can effectively detect a region. When the pressure of the pressure sensor 13 changes, the pressure sensor 13 with the largest increase in pressure value is selected as the effective monitoring device, and the region corresponding to this device is the clamped region.

[0073] The dissolved oxygen sensor can be installed on the underside of the buoyancy component 1 or on the air outlet 7, or in other locations, to measure the oxygen content in the water and output a 4-20mA current signal.

[0074] The intelligent control module is installed on the support body 2. The oxygen pump 5, the electric adjustment bracket 6 and the dissolved oxygen sensor are all electrically connected to the intelligent control module. The intelligent control module can detect the status of the oxygen pump 5 and the electric adjustment bracket 6, receive the monitoring data from the dissolved oxygen sensor, and control the oxygen pump 5 and the electric adjustment bracket 6 to work. The intelligent control module is signal connected to the control terminal 16 to transmit data to the control terminal 16, and the intelligent control module can be controlled through the control terminal 16.

[0075] The power module is installed on the buoyancy component 1. The oxygen pump 5, the electric adjustment bracket 6, and the control host are all electrically connected to the power module to provide power to the oxygen pump 5, the electric adjustment bracket 6, and the control host, so that the oxygen pump 5, the electric adjustment bracket 6 and the control host can operate normally.

[0076] Specifically, such as Figure 1-2 As shown, the power module includes a solar panel 3 and a battery 4 mounted on the bracket 2, and the solar panel 3 and the battery 4 are electrically connected. The oxygen pump 5, the electric adjustment bracket 6, and the control host are all electrically connected to the battery 4. The solar panel 3 can convert solar energy into electrical energy and store it inside the battery 4, thereby reducing the consumption of non-renewable energy.

[0077] The control terminal 16 can be a remote control or an APP installed on a smart device, which enables users to remotely monitor and control the status of the auto-oxygenation device 17.

[0078] The working principle of this invention is as follows: the dissolved oxygen sensor measures the oxygen content in the water, and then the control terminal 16 displays the measured oxygen content value. When the oxygen content value is lower than the standard value, the user can operate the oxygenation pump 5 and the electric adjustment bracket 6 through the control terminal 16. The position of the air outlet 7 is adjusted by the electric adjustment bracket 6. After the air outlet 7 is adjusted, the oxygenation pump 5 is started, and oxygen is delivered to the air outlet 7 through the air guide hose 8 and then discharged through the air outlet 7 to complete the oxygenation work. This can help crab farmers solve problems such as untimely monitoring of dissolved oxygen in the water and improper adjustment methods, help crab farmers improve the quality and yield of crab farming, and increase the income of crab farmers.

[0079] Meanwhile, during use, when a crab clamps onto the air-conducting hose 8, the crab will apply pressure to the outer tube 10, causing the outer tube 10 to pressurize the fluid medium inside the annular space 11. This causes the pressure triggering mechanism to detect the clamping phenomenon of the outer tube 10 and then send a start signal to the intelligent control module. This causes the intelligent control module to automatically start the heating device and rapidly heat the outer tube 10, causing discomfort to the crab and causing it to move away from the air-conducting hose 8, thereby effectively reducing the damage caused by the crab clamping onto the air-conducting hose 8.

[0080] In summary, this technical solution, through the structural arrangement of the control terminal 16 and the self-oxygenating device 17, can remotely monitor and supplement oxygen in crab farming waters. During oxygen supplementation, the position of the oxygen outlet 7 can be freely adjusted according to the user's needs by using the electrically adjustable bracket 6 and the air outlet 7, thus completing the adjustment of various oxygenation schemes. Furthermore, by setting a temperature change layer on the outside of the air guide hose 8, the temperature change can be used to drive the crabs away, effectively reducing the damage caused by the crabs clamping onto the air guide hose 8.

[0081] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
