Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a water quality monitoring buoy with adjustable detection depth. Background Technology

[0002] With the rapid development of aquaculture, the demand for water environment monitoring in pond and large-scale aquaculture scenarios is increasing.

[0003] Current water quality monitoring buoys generally adopt an integrated sensor housing design, encapsulating multi-parameter sensors (such as dissolved oxygen probes, pH electrodes, turbidity meters, etc.) within a rigid housing and using counterweights to achieve vertical levitation. This structure limits the contact depth between the sensor units and the water body to a fixed range (typically 0.1-1 meters below the water surface), creating the following chain of technical defects:

[0004] (1) Limitations of single-point detection: The spatial layout of the sensor cannot break through the physical boundary of the cabin, and can only acquire data of a single water layer;

[0005] (2) Missing vertical profile data: The inability to capture water stratification phenomena (such as dissolved oxygen climax layer, thermocline layer, etc.) leads to farmers misjudging the risk of oxygen deficiency in the bottom water.

[0006] (3) Redundant equipment deployment: To obtain data at different depths, buoys need to be deployed multiple times, which increases the equipment purchase cost by 200%-300%;

[0007] (4) Lack of dynamic monitoring: Fixed structures cannot respond to meteorological changes (such as convection between upper and lower water layers caused by rainstorms), resulting in delayed warnings of abnormal water quality.

[0008] It is evident that traditional water quality monitoring buoys mostly employ fixed sensor designs, only acquiring surface or single-depth water quality data (such as dissolved oxygen, pH, temperature, ammonia nitrogen, etc.). This makes it difficult to reflect the stratified changes in the vertical profile of the water body. Phenomena such as eutrophication and thermocline formation in the bottom water directly impact the survival rate of aquaculture organisms. Existing adjustable monitoring equipment often relies on complex mechanical structures or high-precision drive modules, resulting in high manufacturing costs, high energy consumption, and difficult maintenance. Especially in large-scale aquaculture scenarios, current technologies struggle to simultaneously meet the demands for adjustable detection depth, equipment portability, and cost-effectiveness. Therefore, there is an urgent need to develop a new water quality monitoring device to address these technical challenges. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The purpose of this invention is to provide a water quality monitoring buoy with adjustable detection depth to solve the problems existing in the prior art. It is a low-cost water quality monitoring device that can adapt to different aquaculture scenarios and flexibly adjust the detection depth according to actual needs, so as to achieve accurate collection of multi-dimensional water quality data, provide reliable technical support for the regulation of aquaculture environment, meet the needs of aquaculture farmers for precise and convenient water stratification monitoring, and promote the refined management and sustainable development of aquaculture.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1-3 As shown, this utility model provides a water quality monitoring buoy with adjustable detection depth, such as... Figure 1 As shown, the device includes a float 11, a data acquisition and transmission device 2, a float 5, and a water quality sensor 9. The float 5 is installed at the bottom of the float 11. The data acquisition and transmission device 2 is installed on the float 11. Multiple long tubes 10 are evenly distributed around the float 11. The length of the long tubes 10 is adjustable. Multiple water quality sensors 9 with adjustable positions are installed on the underwater part of each long tube 10. The water quality sensors 9 are connected to the data acquisition and transmission device 2.

[0031] The water quality sensor 9 and the long tube 10 are mechanically decoupled in a separate design, allowing the sensor 9 to be freely distributed along the axial direction of the tube 10. By manually adjusting the length of the tube 10, the sensor 9 can overcome the constraints of the original chamber boundary and directly achieve multi-point water quality sampling from the surface to the bottom layer, constructing a vertical profile data model of the water body. This low-cost water quality monitoring device can adapt to different aquaculture scenarios and flexibly adjust the detection depth according to actual needs, enabling accurate collection of multi-dimensional water quality data. It provides reliable technical support for aquaculture environment control, meets the needs of aquaculture farmers for precise and convenient stratified water monitoring, and promotes refined management and sustainable development of the aquaculture industry.

[0032] Specifically, the upper lifting ring 1 and the lower lifting ring 12 are the lifting ring screw and lifting ring nut, respectively, which are bolted to the float 11. The upper lifting ring 1 can be connected to the shore-based fixed pile to fix the position of the water quality monitoring buoy, or it can be used by a crane to pull and deploy the water quality monitoring buoy. One end of the connecting rope 8 is fixed to the lower lifting ring 12, and the other end can be connected to an anchor to fix the position of the water quality monitoring buoy, or it can be connected only to the counterweight. The upper lifting ring 1 and the lower lifting ring 12 support the anchoring of the shore-based fixed pile and the connection of the underwater counterweight, respectively, to adapt to the wind and wave resistance requirements of different water depth scenarios.

[0033] Four floats 5 are fixed at the four corners of the float plate 11. The float fixing rod 4 passes through the float plate 11 and the floats 5 in sequence and is connected to the float plug 13 by thread. There are keyways on the float fixing rod 4 and the float plate 11. The float fixing rod 4 is limited by a flat key to ensure that it will not rotate.

[0034] The long tube mounting bracket 3 is bolted to the float 11. The long tube 10 is a hollow tube, secured by bolts on the long tube mounting bracket 3 with adjustable clamping tightness. The long tube 10 has graduations, allowing the depth of its underwater end to be determined. Industrial plastic is used instead of stainless steel for the long tube 10, reducing manufacturing costs while maintaining tensile strength and lightening the overall weight of the buoy. The sensor mounting bracket 6 is connected to the long tube 10 via tapered threads, and multiple water quality sensors 9 (temperature sensor, turbidity sensor, dissolved oxygen sensor, conductivity sensor, ammonia nitrogen sensor, etc.) can be fixed around its perimeter and center. The sensor mounting bracket 6 can also be fitted with protective netting to safeguard the water quality sensors 9.

[0035] The design employs a hollow, graduated tube 10 and an adjustable clamping bracket 3. By manually adjusting the insertion depth of the tube 10 into the water (based on precise positioning using the graduated lines), continuous depth detection of the water quality sensor 9 is achieved within a 0-3 meter range, overcoming the limitations of traditional buoy fixing depths. Multiple types of water quality sensors 9 (temperature, dissolved oxygen, ammonia nitrogen, etc.) are integrated onto the sensor bracket 6 of a single tube 10, enabling simultaneous acquisition of vertical profile water quality parameters and solving the challenge of monitoring water stratification.

[0036] The sensor mounting bracket 6 is connected to the long tube 10 via a tapered thread, supporting quick disassembly and independent replacement of the sensor module (if a single sensor fails, the entire module does not need to be repaired).

[0037] The data acquisition and transmission unit 2 is installed at the end of the long tube 10 facing the water surface. The data transmission line inside passes through the hollow long tube 10 and connects to the water quality sensor 9. The data acquisition and transmission unit 2 is responsible for collecting data from the water quality sensor and transmitting it outwards. It supports wireless and wired transmission, and has its own battery that can be charged by a separately installed photovoltaic solar panel or connected to a power supply device on the shore.

[0038] The extended mounting holes 14 can be used to fix counterweights or to install additional long tube holders 3 to accommodate more water quality sensors 9. The extended mounting holes 14 allow for the addition of counterweights or additional long tube holders 3, enabling the parallel deployment of multiple long tubes (such as simultaneously monitoring different areas) to meet the flexible needs of large-scale aquaculture scenarios.

[0039] The installation process of the adjustable detection depth water quality monitoring buoy is as follows: First, install and fix all components on the float plate 11, including the float plate hanging ring 1, the long tube fixing frame 3, the float ball fixing rod 4, the float ball 5, the float plate lower hanging ring 12, and the float ball plug 13; Second, fix the water quality sensor 9 and the data acquisition and transmission device 2 on the long tube 10 according to the detection requirements; Third, fix the long tube 10 on the long tube fixing frame 3 according to the different detection depth requirements of the water quality sensor 9; Fourth, tie the counterweight to the float plate lower hanging ring 12 through the connecting rope 8.

[0040] The adjustable-depth water quality monitoring buoy of this invention has the following features:

[0041] (1) Existing buoy sensors are fixed to a rigid hull, and their detection depth is physically limited (0.1-1 meter). Therefore, this invention adopts a mechanical decoupling design between a split sensor mounting bracket 6 and a long tube 10, allowing the water quality sensor 9 to be freely distributed along the axial direction of the long tube 10. By manually adjusting the length of the long tube 10 (0-3 meters continuously adjustable), the water quality sensor 9 can break through the original hull boundary constraints and directly realize multi-point water quality sampling from the surface to the bottom layer, constructing a vertical profile data model of the water body.

[0042] (2) Traditional single-point detection cannot reflect key stratification features such as dissolved oxygen catalytic layers. Because this invention allows the integration of multiple water quality sensors 9 onto a single long pipe 10, when the pipe 10 extends to a depth of 3 meters, parameters such as dissolved oxygen and temperature at multiple points can be acquired simultaneously. Through gradient data analysis, the location of the thermocline can be accurately identified, helping aquaculture farmers predict the risk of oxygen deficiency at the bottom layer and effectively prevent the risk of fish, shrimp, and crabs surfacing and dying.

[0043] (3) Existing solutions require deploying multiple buoys to obtain data at different depths. Given that the long tube 10 of this invention can dynamically cover a detection range of 0-3 meters, a single device can replace the function of 3-5 fixed-depth buoys in the traditional solution. Combined with the cost reduction strategy of replacing stainless steel with industrial plastic materials, the equipment investment for thousands of acres of water surface is reduced from tens of thousands of yuan to thousands of yuan.

[0044] (4) Traditional integrated cabin failures require the entire unit to be returned to the factory for repair. Because this utility model uses a split sensor mounting bracket 6, a single damaged sensor module can be quickly replaced through water operations (time < 5 minutes), which shortens the maintenance cycle by more than 95% compared to the traditional solution, and the overall availability of the equipment is high.

[0045] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model.
