Description

Technical Field

[0001] The utility model relates to the technical field of underwater water quality monitoring, in particular to an underwater water quality real-time detection system. Background Technique

[0002] Water quality monitoring is a process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality status. The monitoring scope is very wide, including unpolluted and polluted natural waters and various industrial wastewaters, etc.; a water quality real-time monitoring sensor is a device specifically used for real-time monitoring of water quality parameters in water bodies, which can continuously and automatically monitor water quality parameters and collect data in real time. These sensors can usually monitor multiple water quality indicators to ensure comprehensive monitoring of the water quality status. These sensors need to be placed underwater to ensure the detection effect, but when placed in water for a long time, they are easily damaged and have a low service life.

[0003] Therefore, we propose an underwater water quality real-time detection system to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an underwater water quality real-time detection system.

A plurality of detection holes are arranged on the side wall of the circular hole groove, and sensing probes are hermetically and fixedly arranged in the plurality of detection holes. A cleaning component corresponding to the plurality of detection holes is arranged in the cylindrical shell.

[0007] Preferably, a hemispherical filter screen cover corresponding to the circular hole groove is fixedly arranged at the lower end of the cylindrical shell.

[0008] Preferably, the cleaning component includes a water inlet pipe and a water outlet pipe arranged in the chamber. The water inlet pipe and the water outlet pipe are both fixedly connected with the piston. A plurality of through holes are arranged on the side walls of the end parts of the water inlet pipe and the water outlet pipe. The water inlet pipe is fixedly connected and communicated with an external clean water source, and the water outlet pipe is fixedly connected and communicated with an external water pump.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The system is provided with a cylindrical shell to integrate the detection end structure. A circular hole is provided on the cylindrical shell for water samples to enter. Multiple sensors are arranged on the inner wall of the circular hole. At the same time, the circular hole is closed by a piston. When timing detection is required, the piston can be moved to allow the water sample to contact the detection sensor, so as to perform real-time detection. After the detection is completed, the water sample can be discharged back by moving the piston to protect the sensor.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Refer to Figure 1-2 A real-time underwater water quality detection system shown, including:

[0019] The cylindrical shell 1 as the main body is provided with a circular hole groove at the bottom of the cylindrical shell 1 to allow water samples to enter. At the same time, a piston 2 is hermetically and slidably arranged in the circular hole groove. The piston 2 can control the entry of water samples into the circular hole groove and can also move to discharge water samples from the circular hole groove. In order to control the movement of the piston 2, a chamber communicating with the circular hole groove is arranged in the cylindrical shell 1. A truss 3 is horizontally and fixedly arranged in the chamber. Two electric telescopic rods 4 are symmetrically and fixedly arranged at the lower end of the truss 3, and the telescopic ends of the two electric telescopic rods 4 are fixedly connected to the piston 2. The position of the piston 2 can be controlled by the operation of the two electric telescopic rods 4. At the same time, in order to realize the detection operation, a number of detection holes are arranged on the side wall of the circular hole groove, and sensing probes 5 are hermetically and fixedly arranged in the number of detection holes. The number of sensing probes 5 respectively adopt existing sensors with different detection functions for water samples;

[0020] Even if the water sample is discharged by the piston 2, there will still be a certain residue, which will affect the next detection and the sensing probe 5. Therefore, a cleaning component corresponding to a number of detection holes is arranged in the cylindrical shell 1. The cleaning component includes a water inlet pipe 6 and a water outlet pipe 7 arranged in the chamber. The water inlet pipe 6 and the water outlet pipe 7 are both fixedly connected to the piston 2. A number of through holes are arranged on the end side walls of the water inlet pipe 6 and the water outlet pipe 7. The water inlet pipe 6 is fixedly connected and communicated with an external clean water source, and the water outlet pipe 7 is fixedly connected and communicated with an external water pump. Clean water can be introduced through the water inlet pipe 6 to clean the inside, and the waste water can be discharged through the water outlet pipe 7 after cleaning. In order to prevent the water inlet pipe 6 and the water outlet pipe 7 from affecting the movement of the piston 2, a corrugated pipe section is arranged on both the water inlet pipe 6 and the water outlet pipe 7;

[0021] Simple flushing will leave residual water, which will affect subsequent detection. Therefore, an air inlet pipe 8 and an air outlet pipe 9 are also fixedly arranged in the chamber. The air inlet pipe 8 is fixedly connected and communicated with an external clean air source, which can dry the inside and can also cool the inside (by blowing air into the chamber inside), avoiding the heat accumulation generated by the integration of a number of sensing probes 5. The air outlet pipe 9 is communicated with an external one-way valve. The external clean water source, the external clean air source, the external water pump and the external one-way valve are integrally arranged. The above structures all adopt existing technologies and do not affect the operation of the overall system, so they will not be elaborated here.

[0022] At the same time, when the water sample enters, impurities need to be isolated. A hemispherical filter cover 10 corresponding to the circular hole groove is fixedly arranged at the lower end of the cylindrical shell 1. The hemispherical structure design reduces the risk of complete blockage.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
