Description

Technical Field

[0001] This utility model relates to the field of evaporation observation at meteorological stations, and in particular to a large evaporator for meteorological stations that can remotely clean and change water and control water level. Background Technology

[0002] "Precise monitoring" is the primary link and cornerstone of the China Meteorological Administration's work requirements of "precise monitoring, accurate forecasting, and refined services." It fundamentally determines the accuracy of weather forecasts, the early detection and warning of meteorological disasters, effective decision-making in meteorological disaster prevention and mitigation, the credibility of climate research, and the refinement of public services. Meteorological equipment maintenance and support are the lifeline and fundamental guarantee for achieving "precise monitoring." Through regular inspections, preventative maintenance, and rapid fault repair, equipment downtime is minimized to ensure continuous and stable data acquisition, thus safeguarding the "lifeline" of meteorological operations.

[0003] Taking the National Basic Observation Station in Wuchuan Autonomous County, Zunyi City, Guizhou Province as an example, the maintenance and support of its large-scale evaporators faces challenges such as remote location, rugged mountain roads, adverse weather conditions, and safety risks. Specifically: ① Sudden heavy rains and continuous flooding cause the water level in the large evaporators to overflow, exceeding the maximum water level requirement and necessitating increased maintenance frequency. Each manual maintenance session can take over an hour, during which time data must be treated as missing data, failing to ensure continuous data collection and hindering "precise monitoring." ② High evaporation rates during high-temperature periods easily cause water levels to drop below the minimum, resulting in missing data. For unmanned stations separated from the station, exceeding the time limit for manual water replenishment reduces the usability of evaporation data. ③ High-altitude stations have abundant vegetation and high biodiversity, including insects, birds, and spiders. Frequent biological activity leads to pollution and debris accumulation in the large evaporator water, reducing the accuracy of meteorological data and directly impacting the accuracy of weather forecasts, the scientific rigor of climate research, and the effectiveness of related decision-making. Therefore, it is urgent to equip the large evaporators with intelligent water supply and drainage devices and self-cleaning functions with remote control to achieve remote control of data quality.

[0004] A search revealed that Chinese patent document CN219179625U provides an "Automatic Water Level Control System for Large-Scale Evaporation Observation at a Meteorological Station." This utility model discloses an automatic water level control system for large-scale evaporation observation at a meteorological station, belonging to the field of meteorological station evaporation observation technology. The automatic control system includes an evaporation tank and a measuring tank. One side of the evaporation tank is connected to a first water pipe, and the other end of the first water pipe is connected to the measuring tank. An ultrasonic sensor is installed above the measuring tank. The outer surface of the measuring tank has a lower water level line and an upper water level line from bottom to top. A first glass tube for controlling water addition and a second glass tube for controlling drainage are vertically connected to the first water pipe. Both the first and second glass tubes are equipped with two water level sensors. This utility model provides an automatic evaporator maintenance device for meteorological observation stations, which can automatically control the water level, replacing manual water addition and extraction, reducing measurement errors, and is convenient and practical. However, in this scheme, the first water pump is placed inside the evaporation tank. When the water pump is working, it will inevitably generate heat due to energy conversion and loss, which changes the temperature of the water and alters the natural condition of the water in the evaporator, affecting the evaporation rate. At the same time, the device cannot be remotely controlled, and the liquid level will fluctuate violently during the automatic water addition and dispensing process, causing the evaporation data at that moment to be distorted. Utility Model Content

[0005] The purpose of this invention is to provide a large weather station evaporator that can be remotely cleaned, water changed, and water level controlled. It can remotely monitor the water quality and water level in the evaporation tank, thereby enabling timely drainage, cleaning, and water changing operations.

[0006] To achieve the above objectives, this utility model provides a large evaporator for weather stations capable of remote cleaning, water exchange, and water level control. It includes a water storage tank, a water supply pipe, an evaporation tank, and a drain pipe connected in sequence. A water pump and a water supply solenoid valve are connected sequentially to the water supply pipe outside the water storage tank. A flushing nozzle is also provided at the end of the water supply pipe on the inner wall of the evaporation tank. An electrically controlled water level gauge is installed inside the evaporation tank. A drain solenoid valve is connected to the drain pipe. The system also includes a monitoring camera with an opening facing the top of the evaporation tank. The water pump, monitoring camera, water supply solenoid valve, electrically controlled water level gauge, and drain solenoid valve are all electrically connected to the terminal integration box of a network liquid level alarm controller.

[0007] As a further improvement of this utility model, the electronically controlled water level gauge is a radar water level gauge, which is installed above the inner cavity of the evaporation tank, with the detection end of the radar water level gauge arranged vertically downward.

[0008] As a further improvement of this utility model, the device also includes a louvered box and an evaporation data acquisition sensor module. The end of the drain pipe is connected to the evaporation data acquisition sensor module. The evaporation data acquisition sensor module and the network liquid level alarm controller equipment terminal integration box are both installed inside the louvered box. The monitoring camera is installed on the louvered box.

[0009] As a further improvement of this utility model, the flushing nozzle is a fan-shaped rotating nozzle, and the number of fan-shaped rotating nozzles is at least two and arranged around the center line of the evaporation tank; the end of the water supply pipe is connected to a soft water pipe, which is arranged around the outside of the evaporation tank, the water inlet end of each fan-shaped rotating nozzle is connected to the soft water pipe, and the spray nozzle of each fan-shaped rotating nozzle faces the other side of the inner wall of the evaporation tank.

[0010] As a further improvement of this utility model, the fan-shaped rotary nozzle includes a fixed base, a connecting base, and a fan-shaped nozzle body. The water inlet end of the fan-shaped rotary nozzle is disposed on the fixed base, and the connecting base is detachably connected to one end of the fixed base, with the inner cavities of the two communicating. One end of the fan-shaped nozzle body is rotatably and sealingly connected to the connecting base, with the inner cavities of the two communicating. The other end of the fan-shaped nozzle body is provided with the spray nozzle, which is elongated. The length of the long side of the spray nozzle is greater than the cross-sectional dimension of the water inlet end of the fan-shaped nozzle body, and the length of the short side of the spray nozzle is less than the cross-sectional dimension of the water inlet end of the fan-shaped nozzle body. A fan blade structure is fixedly connected to the middle of the inner cavity of the fan-shaped nozzle body.

[0011] As a further improvement of this utility model, the fan blade structure is fixedly connected to a limiting shaft, and a limiting sleeve is fixedly installed in the inner cavity of the fixed seat. One end of the limiting shaft is inserted into and rotated with the limiting sleeve.

[0012] As a further improvement of this utility model, the water storage tank is connected to a remote water inlet switch.

[0013] Beneficial effects Compared with existing technologies, the advantages of this utility model of a large evaporator for weather stations capable of remote cleaning, water exchange, and water level control are as follows: 1. After the device is operational, the monitoring camera transmits real-time images of the water quality in the evaporation tank. When the water quality declines, the system remotely activates the supply and drainage solenoid valves and the tap water inlet switch. A fan-shaped rotating nozzle cleans and replaces the water inside the evaporation tank. The radar level gauge monitors water level changes in real time and automatically adjusts the evaporator water level according to evaporation observation requirements, keeping the evaporation water level within the normal range. When the evaporation water level exceeds the lower or upper limit due to natural evaporation or heavy rainfall, the radar level gauge remotely alarms and makes a judgment, promptly initiating remote supply and drainage operations by opening and closing the supply and drainage solenoid valves, ensuring continuous, fully automated observation of large-scale evaporation at the meteorological station.

[0014] 2. The electronically controlled water level gauge adopts a radar water level gauge. The radar water level gauge uses a lens to emit high-frequency short-wave electromagnetic waves, which has a high signal-to-noise ratio, small blind zone, good transmission characteristics, and is more convenient to install. It adopts non-contact measurement and does not require the use of a universal flange for aiming. It can realize Bluetooth debugging and configuration, 4G network remote cloud platform data transmission, real-time monitoring of water level, and early alarm through threshold setting to guide business personnel to carry out remote water supply and drainage operations in a timely manner, so as to remotely maintain the water level at the standard height.

[0015] 3. The monitoring camera can continuously monitor changes in water quality and algae growth on the inner wall of the evaporation tank, and initiate cleaning and water replacement operations in a timely manner to ensure that the water in the evaporation tank always maintains a natural water state and to ensure that the monitoring data is true and accurate.

[0016] 4. The purpose of the water storage tank is to allow the tap water to settle in a natural state beforehand, ensuring that the temperature of the water supplied to the evaporator remains at the current atmospheric temperature, thus reducing the impact of temperature differences on the accuracy of the data.

[0017] 5. Equipped with an electric self-priming diaphragm water pump and fan-shaped rotating nozzles, the water pump and water storage tank are connected through multiple fan-shaped rotating nozzles facing different directions. High-pressure water jets impact the tank wall for cleaning, enabling unattended remote control and fully automatic operation. Monitoring and command issuance can be performed via PC or mobile software. It effectively removes scale, algae, dust and other deposits from the inner wall of the evaporation tank. According to remote commands, it automatically empties the old water and injects fresh natural water.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0021] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0022] Example The specific embodiments of this utility model are as follows: Figures 1 to 5 As shown, a large evaporator for a weather station capable of remote cleaning, water exchange, and water level control includes a water storage tank 25, a water supply pipe 20, an evaporation tank 4, and a drain pipe 6 connected sequentially along the water flow direction. A water pump 24 and a water supply solenoid valve 22, located outside the water storage tank 25, are connected sequentially to the water supply pipe 20. A flushing nozzle 18 is also provided at the end of the water supply pipe 20 on the inner wall of the evaporation tank 4. An electrically controlled water level gauge 19 is installed inside the evaporation tank 4. A drain solenoid valve 5 is connected to the drain pipe 6. Both the water supply solenoid valve 22 and the drain solenoid valve 5 are ball valves.

[0023] The device also includes a monitoring camera 15 with an opening facing the top of the evaporation tank 4. The water pump 24, monitoring camera 15, water supply solenoid valve 22, electric level gauge 19, and drain solenoid valve 5 are all electrically connected to the network level alarm controller terminal integration box 14, which is powered by mains power 9. Specifically, the monitoring camera 15 is electrically connected to the network level alarm controller terminal integration box 14 via camera control cable 16; the water supply solenoid valve 22 is electrically connected to the network level alarm controller terminal integration box 14 via water supply solenoid valve control cable 23; the electric level gauge 19 is electrically connected to the network level alarm controller terminal integration box 14 via electric level gauge control cable 21; and the drain solenoid valve 5 is electrically connected to the network level alarm controller terminal integration box 14 via drain solenoid valve control cable 8. The water pump 24 is an electric self-priming diaphragm water pump.

[0024] Among them, the monitoring camera 15 is an Ezviz 4G network 360° panoramic HD smart AI camera. Based on AI algorithms, it can intelligently detect the exposure of the image. When there is reflection from objects in the monitored area and local overexposure occurs, it will automatically adjust the exposure parameters to ensure the clarity of the image details, thereby avoiding the situation where the water quality cannot be seen due to reflection from the water surface.

[0025] The network liquid level alarm controller, model PWC3100, has functions such as liquid level acquisition and display, automatic liquid level control, over-limit alarm, and remote control.

[0026] The controller collects the on-site water level and displays it on the display panel. At the same time, it transmits the data to the Haichuang Cloud Platform via the 4G network. After obtaining the water level information, the platform forwards it to the user terminal, allowing the user to remotely view the real-time liquid level and equipment operating status via mobile phone or computer.

[0027] The automatic water level control function involves the controller collecting and judging the water level. When the water level is lower than the lower control limit, the water pump is started (the lower control limit relay is activated) to replenish water. When the water level is higher than the upper control limit, the water pump is turned off (the lower control limit relay is deactivated) to stop water supply, thereby achieving automatic water level control (the same logic can be used to implement drainage control logic).

[0028] The controller supports a liquid level over-limit alarm function. When the water level exceeds the upper alarm limit, the upper alarm limit relay activates (and deactivates when the water level falls below the upper limit). When the water level falls below the lower limit, the lower alarm limit relay activates (and deactivates when the water level exceeds the lower alarm limit). When the upper and lower alarm limit relays are connected to alarm devices, on-site audible and visual alarms can be achieved, as well as remote alarms via WeChat, SMS, telephone, etc.

[0029] The water inlet of the water storage tank 25 is connected to a remote water inlet switch 26. The remote water inlet switch 26 is electrically connected to the network liquid level alarm controller device terminal integration box 14. The opening and closing of the remote water inlet switch 26 is controlled by the network liquid level alarm controller device terminal integration box 14.

[0030] The lower part of the evaporator 4 is buried below ground level. The upper outer side of the evaporator 4 is arranged with a water ring 3, a soil ring 2, and a concrete ring 1 from the inside to the outside. All three rings are located above ground level. An overflow port 17 communicating with the inner cavity is provided on the upper outer wall of the evaporator 4.

[0031] The electronically controlled water level gauge 19 is a radar water level gauge, installed above the inner cavity of the evaporation tank 4, specifically on the inner wall of the evaporation tank 4. The detection end of the radar water level gauge is arranged vertically downwards, used to measure the water level height inside the evaporation tank 4. The model of the radar water level gauge is the 80G radar water level gauge from Shenzhen Jiajia Eye Technology Co., Ltd.

[0032] The device also includes a louvered box 13 and an evaporation data acquisition sensor module 00. The end of the drain pipe 6 is connected to the evaporation data acquisition sensor module 00. The evaporation data acquisition sensor module 00 and the network liquid level alarm controller equipment terminal integration box 14 are both installed inside the louvered box 13.

[0033] This solution is an improvement upon the E-601B large-scale evaporator. The E-601B large-scale evaporator is listed in the national standard GB / T 21327-2019. The main body of the E-601B large-scale evaporator consists of an evaporation tank (4), a water ring (3), an overflow tank, and an electrical probe system. The evaporation data acquisition sensor module (00) includes the overflow tank and the electrical probe. The instrument measures the liquid level change by triggering an audible signal when the electrical probe contacts the water surface, and calculates the evaporation rate by combining the precipitation and overflow volume.

[0034] A monitoring camera 15 is installed on the upper outer side of the Stevenson screen 13, with its lens angled downwards towards the water surface of the evaporation tank 4. The Stevenson screen 13 is installed above a concrete platform 7 set on the ground. The horizontal distance between the vertical center lines of the evaporation tank 4 and the Stevenson screen 13 is 3000mm.

[0035] The flushing nozzle 18 is a fan-shaped rotating nozzle, and there are at least two fan-shaped rotating nozzles arranged around the center line of the evaporation tank 4. In this embodiment, the diameter of the evaporation tank 4 is 618 mm, and the number of fan-shaped rotating nozzles is three. The larger the diameter of the evaporation tank 4, the more fan-shaped rotating nozzles need to be configured. The end of the water supply pipe 20 is connected to a soft water pipe 28, which is arranged around the outside of the evaporation tank 4. The water inlet end of each fan-shaped rotating nozzle is connected to the soft water pipe 28, and the spray nozzle 1832 of each fan-shaped rotating nozzle faces the inner wall of the evaporation tank 4 on the other side.

[0036] The fan-shaped rotary nozzle includes a fixed base 181, a connecting base 182, and a fan-shaped nozzle body 183. The fixed base 181 is cylindrical, and the water inlet end of the fan-shaped rotary nozzle is located on one end of the fixed base 181. The soft water pipe 28 is connected to the water inlet end of the fixed base 181, and the fixed base 181 passes through the side wall of the evaporation tank 4. The connecting base 182 is detachably connected to one end of the fixed base 181, and the inner cavities of the two are connected. Specifically, the internal thread of one end of the connecting base 182 is threadedly connected to the external thread of one end of the fixed base 181. The inner side wall of the connecting base 182 is provided with a raised first stepped structure, and the end face of the first stepped structure facing the fixed base 181 is provided with an annular sealing gasket 184. The end face of the fixed base 181 and the end face of the first stepped structure together clamp the sealing gasket 184 to form a seal.

[0037] The rotation axis of the fan-shaped nozzle body 183 is arranged horizontally. The fan-shaped nozzle body 183 includes a rotating connecting sleeve 1831 located at one end. The rotating connecting sleeve 1831 is rotatably and sealingly connected to the connecting seat 182 and the inner cavities of the two are connected. Specifically, the connecting seat 182 includes a second stepped structure arranged in an annular pattern on its outer side wall. The rotating connecting sleeve 1831 is sleeved on the outside of the second stepped structure of the connecting seat 182 and the two are rotatably engaged. A plurality of sealing rings 186 are provided between the inner wall of the rotating connecting sleeve 1831 and the outer wall of the second stepped structure. One end of the rotating connecting sleeve 1831 is provided with an annular inner flange. A bearing 185 is provided between the inner flange of the rotating connecting sleeve 1831 and the axial end face of the second stepped structure.

[0038] The other end of the fan-shaped nozzle body 183 is provided with a water nozzle 1832. The water nozzle 1832 is elongated, with the long side of the water nozzle 1832 being longer than the cross-sectional dimension of the water inlet end of the fan-shaped nozzle body 183, and the short side of the water nozzle 1832 being shorter than the cross-sectional dimension of the water inlet end of the fan-shaped nozzle body 183. This not only increases the water pressure of the spray but also expands the spray area, which is beneficial for rinsing the inner wall of the evaporation tank 4. A fan blade structure 187 is fixedly connected to the middle of the inner cavity of the fan-shaped nozzle body 183. The fan blade structure 187 is specifically located inside the rotating connecting sleeve 1831, and the water inlet end of the fan-shaped nozzle body 183 is located at the end of the rotating connecting sleeve 1831.

[0039] The fan blade structure 187 is fixedly connected to the middle of the limiting shaft 188. One end of the limiting shaft 188 is fixedly connected to the inner wall of the fan-shaped nozzle body 183 through at least two connecting plates. A limiting sleeve 189 is fixedly installed in the inner cavity of the fixing seat 181. The outer wall of the limiting sleeve 189 is fixedly connected to the inner wall of the fixing seat 181 through at least two connecting rods. The other end of the limiting shaft 188 is inserted into and rotated with the limiting sleeve 189 to reduce the shaking of the limiting shaft 188.

[0040] During the water spraying process of the fan-shaped nozzle body 183 of the flushing nozzle 18, the water pump 24 delivers water to the soft water pipe 28 and distributes it to each flushing nozzle 18. When the water enters the fan-shaped nozzle body 183 from the fixed seat 181, the water flow impacts the fan blade structure 187 and drives it to rotate relative to the connecting seat 182. Thus, the fan-shaped nozzle body 183 sprays water while rotating, expanding the cleaning range.

[0041] The aforementioned network liquid level alarm controller equipment terminal integration box 14 includes a network liquid level alarm controller. The network liquid level alarm controller is equipped with an industrial-grade PLC (Programmable Logic Controller) and RTU (Remote Terminal Unit). The built-in power supply module converts the mains power 9 into the voltage required by each component, and includes a 4G module, a relay closing control module, etc., to realize functions such as liquid level acquisition and display, 4G network cloud platform terminal transmission, over-limit alarm, and remote water level control.

[0042] The workflow of a large evaporator at a weather station capable of remote cleaning, water exchange, and water level control is as follows: After the tap water inlet remote switch 26 remotely stores water in the water storage tank 25, it starts the power supply of the network liquid level alarm controller equipment terminal integration box 14. The radar water level gauge automatically detects the water level in the evaporation tank 4 and transmits it to the remote control terminal in real time.

[0043] (I) Remote Drainage Control Process. When the water level in the evaporator tank 4 exceeds the normal operating limit, the radar water level gauge will trigger an alarm on the remote maintenance platform. The operator first enters the remote maintenance operation command on the terminal microcomputer and sets the working mode of the evaporation sensor in the data acquisition device to "maintenance mode". Then, the operator remotely opens the relay terminal of the drainage solenoid valve 5 in the terminal integration box 14 of the network liquid level alarm controller with one click. Through the drainage solenoid valve control cable 8, the drainage solenoid valve 5 is opened, the drainage pipeline is connected, and remote automatic drainage operation is realized. The radar water level gauge transmits water level change data in real time. When the water level drops to the lower limit of normal operation, the relay terminal of the drain solenoid valve 5 is disconnected, the drain pipe is shut off, and drainage stops. The effectiveness of this operation is verified by the monitoring camera 15. Finally, the remote maintenance operation command is entered on the terminal microcomputer, and the working mode of the evaporation sensor in the data acquisition device is set to "normal operation". Through the water level over-limit alarm, the remote microcomputer commands the sensor to switch the working mode. This eliminates the situation in Chinese patent document CN219179625U where the business personnel did not receive the alarm in advance during the automatic water addition and discharge process, and the evaporation sensor was always in the normal operation mode. The liquid level would fluctuate violently, but this would not cause the evaporation data to be distorted at this time.

[0044] (II) Remote Water Supply Control Process. When the water level in evaporator tank 4 exceeds the normal operating lower limit, the radar level gauge will trigger an alarm on the remote maintenance platform. The operator first inputs a remote maintenance command on the terminal computer, setting the evaporation sensor in the data acquisition unit to "maintenance mode." Next, the operator remotely activates the water supply solenoid valve 22 relay terminal in the network level alarm controller terminal integration box 14, closing it. Through the water supply solenoid valve control cable 23, the water supply solenoid valve 22 is opened, connecting the water supply pipeline. The water pump 24 starts, adding water from the storage tank 25 to the evaporator tank 4, and the radar level gauge transmits real-time water level change data. When the water level rises to the normal operating upper limit, the water supply solenoid valve 22 relay terminal is disconnected, the water supply pipeline is cut off, and water supply stops. This operation is verified by the monitoring camera 15. Finally, the operator inputs a remote maintenance command on the terminal computer, setting the evaporation sensor in the data acquisition unit to "normal operation mode." If the water in the storage tank 25 is drained, the operator promptly opens the remote tap water inlet switch 26 to replenish the water.

[0045] The remote control described in (a) and (b) above can automatically control the water level, replacing manual water addition and extraction, reducing measurement errors. It is convenient to use and highly practical, and can keep the water level of the large evaporator at the meteorological station within the normal range, fundamentally solving the problem of adjusting the water level of the large evaporator.

[0046] (III) When the monitoring camera 15 transmits the water quality image of the evaporation tank 4 in real time and finds that the water quality has declined, the original dirty water in the evaporation tank 4 is drained in the remote control according to the procedure in (I). Then, clean water is added to the evaporation tank 4 in the remote control according to the procedure in (II). At the same time, the three fan-shaped rotating nozzles 18 pressurize the clean water source in the water storage tank 25 under the pressure of the high-pressure electric self-priming diaphragm water pump 24 to form a high-pressure spray to rinse and change the water at the same time. Repeat the above operation to achieve complete cleaning of the inner wall of the evaporation tank 4 and clean water. The effectiveness of the operation is verified by the monitoring camera 15 to realize remote cleaning and water change of the large evaporator of the meteorological station, which greatly solves the problem of automatic operation and maintenance of high-altitude meteorological observation equipment and injects new momentum into the accurate collection of meteorological data and the improvement of the quality and efficiency of meteorological services.

[0047] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
