Abstract

This utility model discloses a water quality monitoring buoy station with a monitoring module protection structure, including a buoy body, a support frame mounted on the buoy body, and a water quality monitoring unit located below the buoy body. A circular hole is provided through the center of the buoy body. Four longitudinal guide rails are installed inside the support frame, each with a slider. A lifting plate is fixed between the four sliders. An electric lead screw is also installed inside the support frame, with its lead screw nut fixedly connected to the sliders. The lifting plate is connected to the monitoring unit via a connecting rod. The monitoring unit of this water quality monitoring buoy station can be raised and lowered. When the water surface is about to freeze, the monitoring unit can be lifted out of the water, effectively preventing damage to the various sensors of the monitoring unit due to pressure. Furthermore, raising the monitoring unit facilitates later maintenance, eliminating the need to lift the entire water quality monitoring buoy station from the water surface.

Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically a water quality monitoring buoy station with a monitoring module protection structure. Background Technology

[0002] The principle of a water quality monitoring buoy station can be summarized as follows: an automated, integrated, and real-time mobile monitoring platform deployed in open waters, which integrates multiple sensors to measure water quality parameters in situ and continuously, and uses wireless communication technology to transmit the data to the monitoring center in real time. Currently, the monitoring modules of water quality monitoring buoy stations are directly fixed to the bottom or side of the buoy body. The monitoring modules can only be detached from the water when the entire water quality monitoring buoy station is lifted from the water surface. However, when the water surface is frozen, the various sensors of the monitoring modules will be crushed and damaged.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a water quality monitoring buoy station with a monitoring module protection structure. Utility Model Content

[0004] The technical problem solved by this utility model is to propose a water quality monitoring buoy station with a monitoring module protection structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water quality monitoring buoy station with a monitoring module protection structure, comprising a buoy body, a support frame mounted on the buoy body, a water quality monitoring unit disposed below the buoy body, a through-hole at the center of the buoy body, four longitudinal guide rails mounted inside the support frame, each of the four longitudinal guide rails having a slider, a lifting plate being fixed together between the four sliders, an electric lead screw mounted inside the support frame, the lead screw nut of the electric lead screw being fixedly connected to the slider, the lifting plate being connected to the monitoring unit via a connecting rod, the monitoring unit moving through the through-hole at the center of the buoy body, and a temperature sensor mounted on one side of the buoy body.

[0006] Furthermore, the monitoring unit includes an integrated board and several sensors with different monitoring functions. The lifting plate is connected to the integrated board via a connecting rod. Several through holes are provided on the integrated board. Sensor mounting bases are covered on the through holes and fixed with screws. Several sensors with different monitoring functions are respectively installed on their corresponding sensor mounting bases and pass through their respective through holes.

[0007] Furthermore, the lower end face of the integrated plate is equipped with several internally threaded sleeves, which are interconnected with the through holes. The internally threaded sleeves are threadedly connected to mesh tubes, and several sensors with different monitoring functions are inserted into the corresponding mesh tubes.

[0008] Furthermore, the electric lead screw includes a lead screw motor mounted on the float, an end plate mounted on the support frame, a bearing mounted on the bottom of the end plate, a lead screw mounted between the bearing and the output shaft of the lead screw motor, and a lead screw nut threaded onto the lead screw.

[0009] Furthermore, there are four connecting rods, with the upper and lower ends of the connecting rods fixed to the lifting plate and the monitoring unit, respectively.

[0010] Furthermore, the connecting rod is a single rod, with its upper end fixed to the lifting plate. A U-shaped block is installed on the upper end of the monitoring unit, and the bottom end of the connecting rod extends into the groove of the U-shaped block. A nut is fixed on one side of the U-shaped block, and a threaded rod passes through the other side of the U-shaped block laterally. The front end of the threaded rod passes through the U-shaped block and the bottom end of the connecting rod and is threadedly connected to the nut. A handle is fixed to the end of the threaded rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the monitoring unit of the water quality monitoring buoy station in this utility model can be raised and lowered. When the water surface is about to freeze, the monitoring unit can be raised and removed from the water surface, thereby effectively preventing the various sensors of the monitoring unit from being damaged by pressure. Moreover, raising the monitoring unit helps with later maintenance and upkeep, eliminating the need to lift the entire water quality monitoring buoy station from the water surface.

Detailed Implementation

[0013] 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.

[0014] This utility model provides a technical solution: Please see Figure 1-5A water quality monitoring buoy station with a monitoring module protection structure includes a buoy 1, a support frame 2 installed on the buoy 1, a power supply system, a data transmission system, and a data acquisition controller processing and storage module installed on the buoy 1, a water quality monitoring unit 6 under the buoy 1, a through hole 12 at the center of the buoy 1, four longitudinal guide rails 3 installed inside the support frame 2, each of the four longitudinal guide rails 3 is equipped with a slider 4, a lifting plate 5 is fixed together between the four sliders 4, an electric screw is also installed inside the support frame 2, the screw nut of the electric screw is fixedly connected to the slider 4, the lifting plate 5 is connected to the monitoring unit 6 through a connecting rod, the monitoring unit 6 shuttles in the through hole 12 at the center of the buoy 1, and a temperature sensor 11 is also installed on one side of the buoy 1; The temperature sensor 11 on one side of the float 1 can be above the water surface and directly monitor the outdoor temperature. When the outdoor temperature is about to reach the critical value for the water surface to freeze, the temperature sensor 11 will feed the signal back to the controller for processing. The controller will feed the signal back to the electric screw and control the electric screw to start, which will lift the monitoring unit 6 upward until the monitoring unit 6 is removed from the water surface and is in the round hole 12.

[0015] The monitoring unit 6 includes an integrated plate 61 and several sensors with different monitoring functions, such as an H sensor, dissolved oxygen sensor, conductivity / salinity sensor, turbidity sensor, and temperature sensor. It may also include a nutrient salt sensor and a comprehensive index sensor. The lifting plate 5 is connected to the integrated plate 61 via a connecting rod. The integrated plate 61 has several through holes, and sensor mounting bases 62 are covered on the through holes and fixed with screws. Several sensors with different monitoring functions are installed on their respective sensor mounting bases 62, and several sensors with different monitoring functions pass through their respective through holes. First, fix all kinds of sensors on the sensor mounting base 62. Then, pass the sensor through the through hole until it is below the integrated board 61. Then, fix the sensor mounting base 62 to the integrated board 61 with screws. This is to facilitate the installation and removal of the sensor.

[0016] Among them, the lower end face of the integrated plate 61 is equipped with several internal threaded sleeves 63, which are interconnected with the through holes. The internal threaded sleeves 63 are threadedly connected to the mesh tubes 64. Several sensors with different monitoring functions are inserted into the corresponding mesh tubes 64, and the mesh tubes 64 are used to protect the sensors.

[0017] In the above, the electric lead screw includes a lead screw motor mounted on the float 1, an end plate 9 mounted on the support frame 2, a bearing 10 mounted on the bottom of the end plate 9, a lead screw 7 mounted between the bearing 10 and the output shaft of the lead screw motor, and a lead screw nut 8 threaded onto the lead screw 7. The electric lead screw here has the same structure and principle as the electric ball screw in the prior art.

[0018] Example 1 There are four connecting rods, and the upper and lower ends of the connecting rods are fixed to the lifting plate 5 and the monitoring unit 6, respectively.

[0019] Example 2 The connecting rod consists of one rod, the upper end of which is fixed to the lifting plate 5. A U-shaped block 13 is installed on the upper end of the monitoring unit 6. The bottom end of the connecting rod extends into the groove of the U-shaped block 13. A nut is fixed on one side of the U-shaped block 13, and a threaded rod 14 passes horizontally through the other side of the U-shaped block 13. The front end of the threaded rod 14 passes through the bottom end of the U-shaped block 13 and the connecting rod and is threadedly connected to the nut. A handle 15 is fixed to the end of the threaded rod 14. When the handle 15 is turned, the threaded rod 14 is threadedly connected to the nut, and the handle 15 is pressed against one side of the U-shaped block 13, thus locking the U-shaped block 13 and the connecting rod. Conversely, if the U-shaped block 13 and the connecting rod are loosened, the entire monitoring unit 6 can be flipped along the bottom of the connecting rod, making it easier to maintain the monitoring unit 6.

[0020] In the above, the data acquisition controller processing and storage module, power supply system, and data transmission system are consistent with those of the data acquisition controller processing and storage module, power supply system, and data transmission system of the existing buoy station. The data acquisition controller processing and storage module includes: Data acquisition unit: Responsible for automatically collecting readings from each sensor at preset time intervals (e.g., once per hour).

[0021] Controller: Responsible for the power management, operating mode setting, and fault diagnosis of the entire system.

[0022] Power supply system: Solar panels: This is the mainstream power supply method, converting solar energy into electrical energy.

[0023] Storage battery: Stores the electrical energy generated by the solar panels to power the entire system on cloudy or rainy days or at night, ensuring continuous operation.

[0024] Data transmission system (communication link): Wireless communication module: Transmits the collected data to a remote data center or cloud platform via a wireless network. Common communication methods include: GPRS / 3G / 4G / 5G: Utilizing public mobile communication networks, these methods offer wide coverage and high speeds, making them the most common approach.

[0025] Satellite communication: used in areas without mobile signal coverage, such as the open sea and lakes.

[0026] LoRa and NB-IoT are low-power wide-area network technologies suitable for scenarios with extremely high power consumption requirements and small data volumes.

[0027] Buoy stations may also include safety and auxiliary systems.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
