Description

Technical Field

[0001] This utility model relates to the field of aquaculture water quality monitoring technology, and in particular to a freshwater aquaculture water quality monitoring and control device. Background Technology

[0002] Aquaculture refers to the production of raising and breeding aquatic economic animals (fish, shrimp, crabs, shellfish, etc.) and aquatic economic plants in ponds, reservoirs, lakes, rivers and other inland waters (including brackish water). It is an important part of the inland aquaculture industry. The quality of freshwater is one of the important factors affecting the growth of aquatic products in aquaculture. Therefore, it is necessary to use water quality monitoring and control devices to monitor the quality of freshwater at all times.

[0003] Existing water quality testing devices often rely on multiple ropes to fix them to the water surface. This method is not only cumbersome to operate, but also makes it difficult to ensure the stability of the device on the water surface. Once fixed, the position of the device is difficult to adjust. If it needs to be moved to other water areas for monitoring, a complicated fixing operation must be carried out again. The limitations of this fixing method restrict the flexibility and convenience of water quality testing devices. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a freshwater aquaculture water quality monitoring and control device, comprising a float, a conical box mounted above the float, a fixing block fixedly mounted inside the conical box, a rotating shaft between the fixing blocks, winding cylinders on both sides of the rotating shaft, a settling cylinder inside the float, a receiving groove inside the settling cylinder, an opening around the settling cylinder, an air inflator mounted at the top of the receiving groove, and an expansion airbag below the air inflator; an installation groove inside the fixing block, a return spring inside the installation groove, one end of the return spring fixedly mounted inside the installation groove, and the other end of the return spring fixedly mounted at one end of the winding cylinder.

[0005] As an improvement to the above technical solution, an mounting plate is installed on the top of the conical box, a fixing plate is fixedly installed on the top of the mounting plate, and solar panels are fixedly installed on both sides of the fixing plate.

[0006] As an improvement to the above technical solution, a receiving plate is provided inside the conical box, and a placement groove is opened above the receiving plate, and a detector is installed inside the placement groove.

[0007] As an improvement to the above technical solution, a connecting rope is connected above the settling cylinder, and a connecting rope is wound inside the winding cylinder, the length of which is greater than the water depth.

[0008] As an improvement to the above technical solution, a gap is left between the settling cylinder and the float, and the expansion airbag can fill the interior of the settling cylinder.

[0009] The beneficial effects of this utility model are as follows: An air inflator and an expansion airbag are installed in the internal receiving tank of the settling cylinder. This allows operators to control the operation of the air inflator to inflate or deflate the expansion airbag as needed. When the airbag is inflated, its volume expands, pushing the water inside the settling cylinder out through the external openings, thereby reducing the weight of the cylinder and increasing its buoyancy, making the device lighter and easier to move on the water surface. Conversely, when the device needs to be fixed on the water surface, the air in the airbag can be released, allowing the water inside the settling cylinder to flow back in, increasing its weight and thus stabilizing the device. This method of controlling the increase and discharge of water in the cylinder by inflating and deflating the airbag is not only simple to operate but also greatly improves the stability of the device on the water surface and the flexibility of monitoring operations, providing more reliable technical support for freshwater aquaculture water quality monitoring.

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0014] Please see Figure 1-2This utility model provides a technical solution: a freshwater aquaculture water quality monitoring and control device, including a float 10, a conical box 11 installed above the float 10, a fixing block 20 fixedly installed inside the conical box 11, a rotating shaft 21 arranged between the fixing blocks 20, winding cylinders 22 opened on both sides of the rotating shaft 21, a settling cylinder 23 arranged inside the float 10, a receiving groove 24 opened inside the settling cylinder 23, an opening 25 opened on the periphery of the settling cylinder 23, an air inflator 26 installed at the top of the receiving groove 24, and an expansion airbag 27 arranged below the air inflator 26; an installation groove 28 opened inside the fixing block 20, a return spring 29 arranged inside the installation groove 28, one end of the return spring 29 fixedly installed inside the installation groove 28, and the other end of the return spring 29 fixedly installed at one end of the winding cylinder 22.

[0015] In this embodiment, an air inflator 26 and an expansion airbag 27 are installed in the receiving groove 24 inside the settling cylinder 23. This allows the operator to control the operation of the air inflator 26 to inflate or deflate the expansion airbag 27 as needed. When the airbag is inflated, its volume expands, pushing the water inside the settling cylinder 23 out through the outer opening 25, thereby reducing the weight of the cylinder and increasing the buoyancy, making the device lighter and easier to move on the water surface. Conversely, when the device needs to be fixed on the water surface, the air in the airbag can be released to allow the water inside the settling cylinder 23 to flow back in, increasing its weight and thus stabilizing the device. This method of controlling the increase and discharge of water in the cylinder by inflating and deflating the airbag is simple to operate, improves the stability of the device on the water surface and the flexibility of monitoring operations, and provides more reliable technical support for freshwater aquaculture water quality monitoring.

[0016] Specifically, an mounting plate 30 is installed on the top of the conical box 11, a fixing plate 31 is fixedly installed on the top of the mounting plate 30, and solar panels 32 are fixedly installed on both sides of the fixing plate 31.

[0017] In this embodiment, by adding an installation plate 30 above the conical box 11 and fixing the fixing plate 31 and the solar panels 32 on both sides, the device can be self-powered by utilizing solar energy resources. The solar panels 32 provide continuous and stable power support for electronic devices such as the air inflator 26 and sensors inside the device, reducing dependence on the traditional power grid and reducing operating costs. Under sufficient sunlight, the solar panels 32 can efficiently convert light energy into electrical energy, ensuring that the device can continuously and stably carry out water quality monitoring. It is particularly suitable for remote or inconvenient freshwater aquaculture areas, providing a more convenient and efficient solution for water quality monitoring and control.

[0018] Specifically, the conical box 11 has a receiving plate 12 inside, and a placement groove 13 is opened above the receiving plate 12. A detector 14 is installed inside the placement groove 13.

[0019] In this embodiment, by setting a receiving plate 12 inside the conical box 11 and opening a placement groove 13 on the receiving plate 12, a stable and easy-to-install and maintain platform is provided for the detector 14. The detector 14 is installed in the placement groove 13 and can accurately and quickly acquire water quality data, such as dissolved oxygen, pH value, temperature and other key parameters, providing real-time water quality information for aquaculture farmers and improving the accuracy and efficiency of water quality monitoring. In addition, placing the detector 14 inside the conical box 11 can effectively avoid interference from the external environment, such as direct sunlight and rain erosion, further ensuring the stability and reliability of the monitoring data and providing strong technical support for the sustainable development of freshwater aquaculture.

[0020] Specifically, a connecting rope is connected above the settling cylinder 23, and a connecting rope is wound inside the winding cylinder 22. The length of the connecting rope is greater than the water depth.

[0021] In this embodiment, the settling cylinder 23 is connected to the winding cylinder 22 by a connecting rope at the top, and the length of the connecting rope is designed to be greater than the actual water depth, so that the settling cylinder 23 can sink to the bottom of the water. The connecting rope is kept taut by the reset spring 29 inside the device, so that the device can be stabilized on the water surface.

[0022] Specifically, there is a gap between the settling cylinder 23 and the float 10, and the expansion airbag 27 can fill the interior of the settling cylinder 23.

[0023] In this embodiment, the gap between the settling cylinder 23 and the float 10 ensures the balance and stability of the device in the water. When the expansion bladder 27 is inflated, it can quickly fill the interior of the settling cylinder 23, thereby increasing the buoyancy of the settling cylinder 23 and allowing the device to float easily on the water surface. Conversely, when the device needs to sink, the buoyancy of the settling cylinder 23 can be reduced by releasing the gas in the expansion bladder, allowing it to sink smoothly into the water. The method of adjusting buoyancy by inflating and deflating the expansion bladder 27 is not only simple to operate and quick to respond, but also greatly improves the adaptability and stability of the device in different water areas and under different environmental conditions, providing a more reliable technical guarantee for freshwater aquaculture water quality monitoring.

[0024] The working principle and usage process of this utility model are as follows: After the device is placed in the water, the solar panel 32 is activated to supply power. As needed, the inflation volume of the air bladder 27 inside the settling cylinder 23 is adjusted by the air inflator 26 to control the rise and fall of the settling cylinder 23 in the water. The return spring 29 and the connecting rope ensure that the device floats stably on the water surface. At the same time, the detector 14 inside the conical box 11 acquires water quality data in real time. When it needs to be moved to another location, the air bladder is filled with gas, and the settling cylinder 23 floats up. The whole process is simple to operate, self-sufficient using solar energy, and provides accurate and efficient water quality monitoring and control support for freshwater aquaculture, ensuring a stable aquaculture environment.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
