Description

Technical Field

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

[0002] Water quality monitoring devices are crucial for aquaculture. They are easy to install and operate, and can monitor water quality in real time to ensure aquaculture safety.

[0003] However, existing water quality testing devices cannot clean the filter screen in real time, which can lead to the filter screen being covered by algae and other plants over time, affecting the accuracy of the test. In addition, they can only test the water quality at a certain depth and cannot test the water quality at different depths, so they cannot fully reflect the true water quality.

[0004] Therefore, a water quality testing device is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing water quality testing devices, such as the inability to clean the filter screen in real time and the limitation that they can only detect water quality at a certain depth and cannot detect water quality at different depths. Therefore, this invention proposes a water quality testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water quality testing device includes a float box. Four hooks are fixedly connected to the outer circumference of the float box. Two hooks have a first connecting ring fixedly connected to their bottoms. Two connecting rods are fixedly connected to the outer circumference of the float box. Tension springs are fixedly connected to the surfaces of the two connecting rods, and floating balls are fixedly connected to the tops of the two tension springs. An electric push rod is fixedly connected to the inner top wall of the float box. A partition is fixedly connected to the inner circumference of the float box, with a through hole in the middle of the partition. One end of the output shaft of the electric push rod passes through the through hole and is fixedly connected to a connecting plate. A stainless steel filter screen is fixedly connected between the two ends of the connecting plate. A bracket is fixed to the inner wall of the stainless steel filter screen, and the surface of the bracket has multiple through mounting holes. Sensors (pH sensors) are installed in each mounting hole. Two second connecting rings are fixedly connected to the circumference of the electric push rod. Two pull ropes are fixedly connected to one end of the output shaft of the electric push rod, and the other ends of the two pull ropes are fixedly connected to the tops of the two floating balls, respectively. The two pull ropes pass through the first and second connecting rings.

[0008] In one possible design, a central control box is fixedly connected to the surface of the float box, a solar panel is fixedly connected to the surface of the central control box, an inverter and a battery are installed inside the central control box and electrically connected to the solar panel, and a lighting lamp is fixedly connected to one side of the central control box.

[0009] In one possible design, the tension spring is circumferentially fitted with a protective sleeve, the two ends of which are fixedly connected to the connecting rod and the floating ball, respectively, and the protective sleeve is made of corrugated pipe.

[0010] In one possible design, a waterproof sealing ring is provided at the sliding point between the electric push rod and the partition.

[0011] In one possible design, two first connecting rods are fixedly connected to the bottom end of the partition, and the bottom ends of the two first connecting rods are fixedly connected to the same first cleaning ring, which contacts the outer wall of the stainless steel filter. Two second connecting rods are fixedly connected to the bottom end of the partition, and the bottom ends of the two second connecting rods are fixedly connected to the same second cleaning ring, which contacts the inner wall of the stainless steel filter. A cleaning sponge is fixedly connected to the inner circumference of the second cleaning ring, and the surface of the cleaning sponge has cross-shaped through holes.

[0012] In one possible design, a counterweight filter is fixedly connected to the bottom of the float box.

[0013] In one possible design, the first and second cleaning rings are made of nylon.

[0014] In this application, when the starting device is activated and the electric push rod pushes the filter screen downwards, the first and second cleaning rings can clean the filter screen. The cleaning sponge has cross-shaped through holes, so when the sensor passes through, it not only cleans the sensor but also does not obstruct its passage. Simultaneously, the pull rope, following the downward movement of the electric push rod, pulls up the two floating balls on both sides, causing the device to move further downwards. This allows for the detection of water in deeper areas. When the electric push rod retracts, the stainless steel filter screen and sensor rise back up and are cleaned again, ensuring thorough cleaning. At the same time, the pull rope loosens, and the floating balls move downwards under the action of the tension spring, giving the device greater buoyancy and causing it to rise.

[0015] Beneficial effects: In this utility model, the water quality detection device can float up and down in the water by means of a floating ball, a pull rope and an electric push rod, so as to detect the water quality at different depths, making the detection data more comprehensive and more reflective of the true water quality.

[0016] In this utility model, the water quality detection device can be cleaned during the water quality detection process by means of a first cleaning ring, a second cleaning ring, and a cleaning sponge, making the device clean and ensuring that the sensor is not affected by algae and other pollutants in the water, thus guaranteeing the accuracy of the device in detecting water quality.

[0017] In this invention, a hook and a counterweight filter are used. The hook can be connected to a rope to fix the position of the device, and the counterweight filter can lower the center of gravity of the device to prevent it from tipping over. At the same time, it can also filter pollutants in the water and protect the internal components. Attached Figure Description
