Description

Technical Field

[0001] The invention relates to the technical field of water quality detection equipment, and in particular to an automatic cleaning device for aquatic sensor. Background Art

[0002] In the process of aquaculture, people need to monitor the water quality in real time online to ensure that aquatic products have a good growth and development environment, thereby increasing aquaculture benefits and reducing the occurrence of aquaculture accidents. Dissolved oxygen and pH value are important indicators of water quality. For this reason, people often use water quality sensors such as dissolved oxygen sensors and pH sensors to monitor aquaculture water in real time online, and adjust the dissolved oxygen content and water pH value in the water in a timely manner according to the monitoring data. Since these sensors are immersed in water for a long time, various impurities such as plankton, plants, algae, and residual bait are easily attached to the surface of their probes, affecting the measurement accuracy. For this reason, people need to clean or maintain the sensor probes frequently, otherwise the data will be inaccurate and the water quality cannot be guaranteed.

[0003] At present, there are two common methods for automatically cleaning the sensor probe: one is to use a water pump to automatically spray water to clean the sensor probe. The disadvantage of this method is that the water pump cover and the inner filter element are easily blocked by various impurities in the water under the strong suction of the water pump, which can easily cause water pump failure and poor water spraying; the other is to use a brush to automatically brush the sensor probe with the help of external force. The disadvantage of this method is that the brush itself is a material that is easily attached to various impurities in the water, and the actual cleaning effect is even more unsatisfactory. Therefore, it is urgent to solve the problem of cleaning the sensor probe. Summary of the invention

[0004] In view of this, in order to solve the problem of cleaning the water quality sensor probe, an embodiment of the present invention provides an automatic cleaning device for aquatic product sensors.

[0010] Furthermore, it also includes a guide bottle, which is arranged on the air flow pipeline between the closed container and the floating body.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figure 1 and 2 An embodiment of the present invention provides an automatic cleaning device for aquatic sensors, including a float 1, an air filling and exhaust component 2, at least one water quality sensor 3, and a closed container 4 arranged on the periphery of each of the water quality sensor probes 301.

[0027] Specifically, the float 1 uses the buoyancy of the water body to make the entire aquatic sensor automatic cleaning device float on the water surface. The float 1 can be designed into a cavity structure of various shapes, and there is no limitation on this. In this embodiment, the float 1 includes a float ball 102 and a float ball top cover 101 detachably connected to the upper part of the float ball 102.

[0028] The float 102 has a hollow disc-shaped cavity structure, and a circular sink 102b is provided on the upper part of the float 102. A plurality of hooks 102a are provided on the outer side of the notch edge of the sink 102b. The float top cover 101 is a spherical cover, which covers the upper part of the float 102. A plurality of screw grooves 101a are provided on the lower edge of the float top cover 101. The number of the screw grooves 101a corresponds to the position of the hooks 102a and they are engaged with each other, so that the float top cover 101 and the float 102 can be detachably connected, which is convenient for disassembly and maintenance. The float top cover 101 is engaged with the upper part of the float 102, and its main functions are to prevent rain, sun, and pollution, and to protect the internal inflation and exhaust components 2 of the float 102.

[0029] The inflation and exhaust component 2 is arranged inside the floating body 1, specifically arranged inside the sink 102b, and protected by the float top cover 101. The function of the inflation and exhaust component 2 is to inflate or exhaust the airflow pipeline 5 between it and the closed container 4, and the closed container 4. The inflation and exhaust component 2 includes a control box, a ventilation pipeline, a circuit board, and an air pump and a solenoid valve controlled by the circuit board arranged in the control box. The control box surface is provided with a ventilation port 201, which is used to ventilate the ventilation pipeline (inflation and exhaust) and is the total air inlet and outlet of the entire cleaning device; the air pump and the solenoid valve are both connected to the ventilation pipeline, and the opening and closing of the ventilation pipeline are controlled by the solenoid valve. One end of the ventilation pipeline is connected to the ventilation port 201 on the surface of the control box to ventilate with the outside, and the other end passes through the surface of the control box to connect to the upper end part 503 of the airflow pipeline 5.

[0030] The number of the water quality sensors 3 can be set to one or more, which is specifically determined according to the water quality data to be detected. At the same time, the water quality sensor 3 can be a variety of types of water quality sensors, which are not specifically limited, and can also be determined according to the type of water quality data to be detected, such as a common pH sensor for detecting pH value or a dissolved oxygen sensor for detecting dissolved oxygen content. In this embodiment, two water quality sensors 3 are used as an example for illustrative description, and the two water quality sensors 3 are respectively a pH sensor 3a and a dissolved oxygen sensor 3b.

[0031] Please refer to Figure 2 and 3The water quality sensor 3 is vertically arranged and fixed on the fixing frame 7, and the upper part of the fixing frame 7 is connected to the floating body 1 so that the water quality sensor 3 is suspended in the water body. In this embodiment, a connecting rod 703 is provided on the upper part of the fixing frame 7, and the upper end of the connecting rod 703 is connected to the floating ball 102. A plurality of mounting structures are provided on the side of the fixing frame 7, and the mounting mechanism specifically includes a fixed pressure cover 701 for fixing the pH sensor, and a U-shaped holder 702 for fixing the dissolved oxygen sensor 3b.

[0032] At the same time, the two water quality sensors 3 are also connected to the circuit board through lines. Here, the two water quality sensors 3 are arranged with their probes facing downward and at the same height. The upper parts of the two water quality sensors 3 are provided with connectors 302. The circuit board is provided with a line interface 202 exposed from the upper surface of the control box. The connector 302 is connected to the line interface 202 through a line. The circuit board supplies power to the water quality sensor 3 and obtains the data collected by the water quality sensor 3.

[0033] The closed container 4 is arranged at the lower part of the water quality sensor probe 301, and is sleeved on the outer periphery of each water quality sensor probe 301. The upper end of the closed container 4 is connected to the water quality sensor probe 301, and the water quality sensor probe 301 is extended into the closed container 4. Here, the closed container 4 is cylindrical, and a container bracket 405 is provided on the upper end of the closed container 4. A plurality of closed containers 4 can share one container bracket 405, and the container bracket 405 is fixedly connected to the lower end of the fixing frame 7, and a water seal 404 connected to the water quality sensor probe 301 is provided on the upper end of the closed container 4.

[0034] Please refer to Figure 3 and 4 , the closed container 4 is provided with a flushing hole 401 opposite to the water quality sensor probe 301, and the flushing hole 401 is preferably arranged opposite to the water quality sensor probe 301. In this embodiment, the lower end of the closed container 4 is provided with a flushing cover 402, and the lower sealing is achieved by the flushing cover 402. The flushing hole 401 is arranged on the flushing cover 402, and is arranged opposite to the water quality sensor probe 301 up and down. In addition, the flushing cover 402 is also provided with a bypass hole 403 around the flushing hole 401, and the bypass hole 403 is used to block larger impurities from entering the closed container to prevent blockage and assist drainage. The flushing hole 401 is raised relative to the bottom surface of the flushing cover 402, so that the distance between the water quality sensor probe 301 and the flushing hole 401 is shortened, so that the water body has a better flushing effect. The bypass hole 403 is arranged on the bottom surface of the flushing cover 402, so that the water in the closed container 4 can be completely discharged when exhausting.

[0035] The closed container 4 is connected to the gas filling and exhaust component 2 through the airflow pipeline 5, so that the air pressure inside the closed container 4 and the ventilation pipeline inside the gas filling and exhaust component 2 are kept the same. Specifically, the upper end portion 503 of the airflow pipeline 5 is connected to the ventilation pipeline of the gas filling and exhaust component 2, and a plurality of airflow branches 501 are provided at the lower end of the airflow pipeline 5. The number of the airflow branches 501 is the same as the number of the closed containers 4. Each of the airflow branches 501 is connected to a closed container 4, and the pipe diameter of the airflow branch 501 should be larger than the aperture of the flushing hole 401. At the same time, a stopper clamp 502 can be provided on each of the airflow branches 501, and the opening and closing of the airflow branches 501 can be controlled by the stopper clamp 502.

[0036] When the inflating and exhausting component 2 exhausts air, it changes the pressure difference between the inside and outside of the closed container 4, so that the external water enters the closed container 4 through the flushing hole 401 to flush the water quality sensor probe 301. That is to say, the solenoid valve is opened to make the ventilation pipeline conductive, and the closed container 4, the airflow pipeline 5, and the guide bottle 6 discharge gas to the outside through the inflating and exhausting component 2, and the internal air pressure is reduced. Based on the principle that the flow rate of the fluid in a narrow channel will be accelerated, the flow rate of the external water will be increased by multiples when it enters the closed container 4 along the flushing hole 401 under the action of water pressure, thereby forming a water column to flush the water quality sensor probe 301. After being flushed by the accelerated water body, the water quality sensor 3 will be more accurate because the impurities on the surface of the probe 301 are flushed away. Then, the water entering the closed container 4 will rise along the airflow branch 501 until the floating height of the float 102. After the water body is stable, the water quality sensor 3 is controlled to detect the water body to obtain stable detection data.

[0037] In order to clean the water quality sensor probe 301 for a longer time, the automatic cleaning device for aquatic sensor is further provided with a guide bottle 6, which is arranged on the airflow pipeline between the closed container 4 and the gas filling and exhaust component 2, and is specifically connected in series to the upper part of the airflow pipeline 5 and fixed on the connecting rod 703. The guide bottle 6 can accommodate more incoming water when the gas filling and exhaust component 2 is exhausted to achieve a longer cleaning of the water quality sensor probe 301, so that more impurities attached to the surface of the water quality sensor probe 301 can be washed away, so that the response speed of the water quality sensor 3 is significantly improved.

[0038] In contrast, the air-filling and air-exhausting component 2 can also inflate to change the pressure difference between the inside and outside of the closed container 4, so that the water inside the closed container 4 is discharged from the flushing hole 401. Specifically, the air pump in the air-filling and air-exhausting component 2 and the air-flow pipeline 5 are inflated to increase the air pressure inside the pipeline, and the air-flow pipeline 5, the guide bottle 6 and the water inside the closed container 4 are squeezed under the action of the air pressure to be discharged from the flushing hole 401 and the bypass hole 403, so that the water quality sensor probe 301 can be prevented from being immersed in the water for a long time, and the attachment of impurities and pollutants in the water can be reduced.

[0039] The working process of the above-mentioned automatic cleaning device for aquatic sensor is as follows: when it is necessary to detect the water quality, the air-filling and air-exhausting component 2 exhausts air, reduces the air pressure in the closed container 4, and allows water to enter through the flushing hole 401 to flush the water quality sensor probe 301, and after the air is exhausted and the water in the closed container 4 is stable, the water is detected through the water quality sensor 3; after the detection is completed, the air-filling and air-exhausting component 2 is inflated until the water in the closed container 4 is completely discharged to prevent the water quality sensor probe 301 from being immersed in the water. In this way, regularly exhausting and inflating the float 102 can reduce the attachments on the water quality sensor probe 301 and better clean it, improve the detection accuracy of the water quality sensor 3, and extend the maintenance cycle of the water quality sensor.

[0040] The above-mentioned automatic cleaning device for aquatic sensor can clean all water quality sensors 3 at the same time. In addition, since each of the air flow branches 501 is provided with a stopper clamp 502, the opening and closing of the air flow branches 501 can be controlled by the stopper clamp 502, thereby achieving cleaning of one or more of the water quality sensors 3.
