Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality detector. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water and various industrial wastewater, etc.

[0003] During the detection process, due to the presence of floating objects on the water surface, when filtering using a filter device, the filter device will inevitably be blocked, so the filter device needs to be cleaned. At the same time, during the flow of water, small particles of impurities in the water flow are easy to adhere to the components, resulting in affecting the detection effect and subsequent detection work. Utility Model Content

[0004] The purpose of the utility model is to provide a water quality detector to overcome the above-mentioned defects in the prior art.

[0005] A water quality detector according to the utility model comprises a detection cylinder, the circumference of which is provided with uniformly distributed liquid inlets, the lower end of which is provided with a detector and a liquid discharge pipe, each of which is connected with an electromagnetic sliding door capable of sliding up and down, the lower end of which is connected with an electromagnetic mechanism, an indicator light is embedded in the upper end of the detection cylinder, a fixed disk is fixed in the detection cylinder at the height of the liquid inlet, a rotating rod is rotatably connected in the fixed disk, and uniformly distributed clearing nozzles are fixed on the outer circumference of the rotating rod. A filter cartridge is embedded on the cleaning rod, a drainage cartridge is fixedly arranged at the lower end of the fixed disk, a drainage cavity is opened on the fixed disk and connected to the upper end of the drainage cartridge, a spiral guide plate is fixedly arranged in the drainage cartridge, a rotating wheel is fixedly arranged at the lower end of the rotating rod, a cavity is opened at the rotating wheel, which is evenly distributed circumferentially and opened up and down, the cavity is arranged at an acute angle to the horizontal plane, and the angle is greater than the angle of water flow entering from the lower end, the rotating wheel is arranged at the lower end of the drainage cartridge, and both the upper and lower ends are concavely arranged.

[0006] Optionally, a float control box is fixedly provided in the detection cylinder, a float control device is fixedly provided at the lower end of the float control box, a connecting pipe is fixedly provided at the upper end of the float control device, the connecting pipe extends upward into the float control box, and there is a gap between the connecting pipe and the upper end of the float control box, and the lower end of the float control box is separately provided with evenly distributed drainage ports, and a pressure valve is provided in the drainage port.

[0007] The beneficial effects of the utility model are:

[0008] The guide plate guides the fluid so that the fluid entering the discharge cylinder through the discharge cavity is concentrated and falls from the lower end of the guide plate to the rotating wheel, thereby concentrating the water flow at the rotating wheel and increasing the impact force of the water flow on the rotating wheel, thereby reducing the occurrence of debris adhering to the open cavity, thereby reducing the error in the next detection process.

[0009] The flow of water drives the rotating wheel to rotate, and then the fixed connection between the rotating wheel and the rotating rod drives the cleaning rod connected to the rotating rod to rotate circumferentially, so that floating objects attached to the fixed plate are removed by the cleaning rod, and the filter cartridge is arranged in a boss shape, and the clogging effect of the filter holes at the filter cartridge is reduced by increasing the height of the filter cartridge.

A drainage cartridge 23 is fixedly arranged at the lower end of the fixed disk 14. A drainage cavity 26 is opened on the fixed disk 14 and is located at the upper end of the drainage cartridge 23. A spiral guide plate 24 is fixedly arranged in the drainage cartridge 23. A rotating wheel 22 is fixedly arranged at the lower end of the rotating rod 20. An opening 25 which is evenly distributed in the circumference and opened up and down is opened at the rotating wheel 22.

The rotating wheel 22 is arranged at the lower end of the drainage cartridge 23, and both the upper and lower ends are arranged concavely.

[0023] Put the detection tube 10 into the water surface, immerse the electromagnetic slide door 12 into the liquid surface, and the user controls the electromagnetic mechanism to work. At the lower end of the electromagnetic slide door 12, the electromagnetic mechanism generates a magnetic attraction force to attract the electromagnetic slide door 12, so that the electromagnetic slide door 12 slides downward, and the liquid inlet 11 evenly distributed on the outer periphery of the detection tube 10 opens, and the liquid can enter the detection tube 10 through the liquid inlet 11. The liquid flows to the fixed disk 14. During the flow of the liquid, large-area debris floating on the water surface is adsorbed by the fixed disk 14, and the debris accumulates on the upper end surface of the fixed disk 14.
