Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to an intelligent air-saving oxygen control box. Background Art

[0002] Aquaculture is the human-controlled breeding, cultivation, and harvesting of aquatic plants and animals. It generally encompasses the entire process from seedling to aquatic product under artificial breeding and management. Most aquatic products are cultivated intensively, requiring an oxygen supply system to continuously introduce oxygen into the water during the cultivation process to maintain dissolved oxygen levels. This provides optimal conditions for high-density cultivation and achieves high yields.

[0003] In the existing oxygen supply device, the flow rate of the oxygen is controlled by manually adjusting the flow rate or adjusting the flow rate switch with a solenoid valve.

[0004] Manual adjustment is primarily manual and lacks intelligent control. Customers cannot be informed of any issues with normal water oxygenation caused by air leakage and pressure loss at the back end. Air usage is unknown, and leaks cause waste that customers are unaware of. Furthermore, water pressure and flow are manually adjusted using simple ball valves, which are difficult to control and can easily damage back-end oxygen pipelines and aeration equipment, such as a bursting microporous ceramic aeration plate.

[0005] In addition, when adjusting manually, it is easy to produce errors in the observation of various instrument parameters, and the adjustment is inconvenient; and the equipment is in a humid environment for a long time, which makes it easy to rust and shorten the equipment life.

[0006] Therefore, in response to the above problems, it is urgent to design an intelligent oxygen control box to realize real-time regulation of the dissolved oxygen content in water, achieve the purpose of energy conservation, and replace the traditional manual adjustment method to realize intelligent control of the dissolved oxygen content in water. Utility Model Content

[0007] The purpose of this utility model is to provide an intelligent air-saving oxygen control box to solve the problems of inconvenient control and adjustment of dissolved oxygen content in water and low intelligence level mentioned in the above background technology. The following technical solution is provided: an intelligent air-saving oxygen control box, comprising:

[0008] The box body is provided with a ventilation pipeline inside the box body, and the ventilation pipeline is connected with a solenoid valve, a filter, a pressure gauge, and a temperature and pressure sensor in sequence;

[0009] The rear end of the temperature and pressure sensor is connected to a pressure reducing valve, which in turn is connected to an electric proportional control valve and a mass flowmeter. The end of the mass flowmeter is connected to the outside of the box through a vent line. The end of the vent line extends outside the box and is connected to a float flowmeter. A second temperature and pressure sensor for temperature regulation is located above the pressure reducing valve.

[0010] The solenoid valve, temperature and pressure sensor, electric proportional control valve, mass flow meter and second temperature and pressure sensor are all controlled by PLC.

[0011] In this technical solution, the cabinet uses a carbon steel spray-coated casing, which effectively reduces corrosion caused by moisture and reduces contact between components inside the cabinet and moisture, greatly extending the overall life of the equipment. When in use, the entire device is controlled by a PLC. The operator enters the target dissolved oxygen rate value on the Android screen. The PLC compares the target value with the actual dissolved oxygen sensor data. Based on the comparison result, the electric proportional control valve controls the oxygen intake, ultimately ensuring that the dissolved oxygen rate data reaches the target dissolved oxygen value.

[0012] In order to ensure the airtightness of the device, a set of solenoid valves can be added at the outlet. At this time, the inlet solenoid valve and the outlet solenoid valve control the on and off of the oxygen pipeline. They automatically open when starting work and automatically close when stopping work. When an emergency alarm occurs, the PLC can control it to automatically cut off, thereby ensuring that oxygen operation is no longer carried out when the device fails.

[0013] Advantageously, to ensure the device's accurate temperature detection, a set of temperature and pressure sensors can be added to the outlet. When the device is operating, the inlet and outlet temperature and pressure sensors collect information about the inlet and outlet temperature and pressure. The operator then enters the upper and lower alarm limits for the box's temperature and pressure on the control terminal (Android screen). When the PLC controls the inlet and outlet temperature and pressure sensors and compares the collected values, the system issues an alarm. If the backend loses pressure due to a leak, for example, the temperature and pressure sensors will detect this immediately, triggering the alarm device through the host computer and simultaneously sending a warning signal to the customer.

[0014] In any of the above technical solutions, further, an inlet stop valve is provided between the air inlet end of the ventilation line and the solenoid valve. A second stop valve is provided between the temperature and pressure sensor and the pressure reducing valve. A second pressure gauge is connected between the electric proportional control valve and the pressure reducing valve, and a third stop valve is provided between the second pressure gauge and the electric proportional control valve. A fourth stop valve and a fifth stop valve are provided between the electric proportional control valve and the mass flow meter, and between the mass flow meter and the float flow meter, respectively.

[0015] In this technical solution, a stop valve is set at each node controlled by the PLC. When the parts of the equipment need to be replaced, it is only necessary to close the stop valve at each node to cut off the oxygen path. When the equipment is running, all the stop valves are in the path state.

[0016] By measuring the pressure values ​​on both the pressure gauge and the second pressure gauge, it is possible to determine if there is a leak in the pipeline. Combined with an electric proportional control valve, automatic pressure regulation is achieved, allowing for precise pressure and flow control to adjust the overall pressure and flow, while also protecting the downstream oxygen pipeline and aeration equipment.

[0017] During operation, the mass flow meter collects instantaneous flow and calculates cumulative flow, generating flow statistics and a time-based oxygen consumption curve. The mass flow meter and float flow meter allow customers to monitor instantaneous flow and cumulative gas usage at any time, facilitating gas cost control. Furthermore, the mass flow meter allows for a maximum gas usage threshold. If gas usage exceeds this threshold, the host computer triggers a warning device, notifying the customer to investigate the cause of the abnormality.

[0018] In addition, this device can monitor the dissolved oxygen in the water by adding a precision probe. According to the set dissolved oxygen set value, the host can control the electric regulating valve to achieve real-time adjustment of the gas flow, so as to effectively reduce the impact of power outages.

[0019] The beneficial effects of this utility model include: By comparing dissolved oxygen values ​​with the calibrated range, the PLC controls the electric proportional control valve to stabilize the dissolved oxygen value; the two solenoid valves automatically open and close, ensuring operational safety; and the PLC controls the temperature and pressure sensors to collect the maximum temperature and pressure values ​​to monitor temperature and pressure stability, incorporating an alarm device to provide real-time operator alerts. Furthermore, a mass flow meter enables the collection and reporting of real-time flow data. This provides human-computer interaction and a high level of intelligence, enabling intelligent statistical analysis of dissolved oxygen rates and oxygen consumption during each time period, thus achieving intelligent monitoring and control of dissolved oxygen in the pool.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0025] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0026] Example 1:

[0027] like Figure 1 As shown, this embodiment provides an intelligent air-saving oxygen control box, including:

[0028] The box body 10 has a ventilation pipe 11 inside, and the ventilation pipe 11 is connected to the solenoid valve 20, the filter 30, the pressure gauge 40, and the temperature and pressure sensor 50 in sequence;

[0029] The rear end of the temperature and pressure sensor 50 is connected to a pressure reducing valve 60, which is also connected to an electric proportional control valve 70 and a mass flowmeter 80. The end of the mass flowmeter 80 is connected to the outside of the housing 10 through a ventilation line 11. The end of the ventilation line 11 extends outside the housing 10, and a float flowmeter 90 is connected to the outside of the ventilation line 11. A second temperature and pressure sensor 91 for temperature regulation is provided at the upper end of the pressure reducing valve 60.

[0030] The solenoid valve 20 , the temperature and pressure sensor 50 , the electric proportional control valve 70 , the mass flow meter 80 and the second temperature and pressure sensor 91 are all controlled by the PLC.

[0031] In this technical solution, the housing 10 is made of a carbon steel spray-coated shell, which can effectively reduce corrosion caused by moisture and reduce the contact of components inside the housing with moisture, greatly improving the overall life of the device. When the device is in use, the entire device is controlled by a PLC, and an alarm device is installed on the PLC to alert the operator.

[0032] The operator enters the target dissolved oxygen rate on the Android screen. The PLC compares the target value with the actual dissolved oxygen sensor reading. Based on this comparison, the electric proportional control valve 70 controls the oxygen intake, ultimately bringing the dissolved oxygen rate reading to the target value. To ensure the airtightness of the device, a set of solenoid valves 20 can be added at the outlet. In this case, the inlet and outlet solenoid valves control the on-off of the oxygen pipeline, automatically opening when operation begins and closing when operation stops. In the event of an emergency alarm, the PLC can control the automatic disconnection, ensuring that oxygen flow is not performed in the event of a device failure.

[0033] Advantageously, to ensure the device's accurate temperature detection, a set of temperature and pressure sensors 50 can be added to the outlet. When the device is operating, the temperature and pressure sensors 50 at the inlet and outlet collect data on the inlet and outlet temperature and pressure. The operator then writes the upper and lower alarm limits for the box's temperature and pressure on the control terminal (Android screen). When the PLC controls the temperature and pressure sensors 50 at the inlet and outlet and compares the collected values, the system issues an alarm. If the backend loses pressure due to a leak, for example, the temperature and pressure sensors 50 will promptly detect the loss and trigger the alarm device through the host computer, simultaneously sending a warning signal to the customer.

[0034] In a preferred embodiment of the present invention:

[0035] like Figure 2 As shown, specifically, an inlet stop valve 12 is provided between the air inlet end of the ventilation line 11 and the solenoid valve 20. A second stop valve 13 is provided between the temperature and pressure sensor 50 and the pressure reducing valve 60. A second pressure gauge 41 is connected between the electric proportional control valve 70 and the pressure reducing valve 60, and a third stop valve 14 is provided between the second pressure gauge 41 and the electric proportional control valve 70. A fourth stop valve 16 and a fifth stop valve 17 are provided between the electric proportional control valve 70 and the mass flowmeter 80, and between the mass flowmeter 80 and the float flowmeter 90, respectively.

[0036] In this technical solution, a stop valve is set at each node controlled by the PLC. When the parts of the equipment need to be replaced, it is only necessary to close the stop valve at each node to cut off the oxygen path. When the equipment is running, all the stop valves are in the path state.

[0037] By measuring the pressure values ​​at both pressure gauge 40 and second pressure gauge 41, it's possible to determine if there's a leak in the pipeline. This, combined with the electric proportional control valve 70, automatically adjusts the pressure, precisely regulating both pressure and flow, while also protecting the downstream oxygen pipeline and aeration equipment.

[0038] During operation, the mass flow meter 80 collects instantaneous flow and calculates cumulative flow, generating flow reports and periodic oxygen consumption curves. The mass flow meter 80 and float flow meter 90 allow customers to monitor instantaneous flow and cumulative gas usage at any time, facilitating gas cost management. Furthermore, the mass flow meter 80 allows for a maximum gas usage threshold. If gas usage exceeds this threshold, a warning device is triggered on the host computer, informing the customer to investigate the cause of the abnormality.

[0039] In addition, this device can monitor the dissolved oxygen in the water by adding a precision probe. According to the set dissolved oxygen set value, the host can control the electric regulating valve to achieve real-time adjustment of the gas flow, so as to effectively reduce the impact of power outages.

[0040] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
