Description

Fluorescence method dissolved oxygen measuring instrument simple and convenient to operate

Technical Field

The utility model relates to the field of dissolved oxygen meters, in particular to a fluorescence dissolved oxygen meter with simple and convenient operation.

Background

The fluorescence method dissolved oxygen measuring instrument adopts an innovative fluorescence method to replace a traditional membrane electrode, does not need to replace a membrane and electrolyte, reduces the maintenance workload, improves the working reliability, and is particularly suitable for severe working conditions in the field of sewage treatment. In addition, the fluorescence sensor does not consume oxygen, so the fluorescence sensor has no requirements on flow rate and stirring and is not interfered by substances such as sulfide and the like. The fluorescence method dissolved oxygen measuring instrument is based on the fluorescence quenching principle. The irradiation of blue light onto the phosphor excites the phosphor and emits red light, the time and intensity of which is inversely proportional to the concentration of oxygen molecules, since oxygen molecules can carry away energy (quenching effect). The concentration of oxygen molecules can be calculated by measuring the phase difference between the excited red light and the reference light and comparing with an internal calibration value.

The existing fluorescence method dissolved oxygen measuring instrument comprises a host installation box 1, wherein the host installation box is arranged on the inner side of a railing, a host is arranged in the host installation box, a cable through hole 11 is formed in one side of the lower portion of the host installation box, one end of a connecting cable 2 is arranged in the host installation box and connected with the host, and the other end of the connecting cable penetrates through the cable through hole to be connected with a sensor 3. Before the dissolved oxygen amount of the water body in the pool body is measured, a measurer positioned on the bridge body holds the connecting cable by hand to place the sensor into the water body of the pool body. When the sensor needs to be replaced or repaired, a measuring person on the bridge holds the connecting cable to pull the sensor back.

The existing fluorescence method dissolved oxygen measuring instrument has the following defects:

1. when the measuring personnel pull the sensor back, the sensor is blocked by the lower surface of the bridge body and cannot be pulled back. Because the thickness of the pontic is great and railing and with the pontic side clearance setting, the survey crew is difficult to take back the sensor with the hand, the operation is very inconvenient.

2. In the measuring process, under the action of gravity of the sensor, the connecting cable is in a stressed stretching state, so that the connecting cable is always abutted against the side vertex angle of the bridge body. After long-time measurement, the connection cable is damaged due to the fact that the connection cable is rubbed with the top corner of the side edge of the bridge body.

3. In the measuring process, the sensor can not be fixed in the water body, and along with the rapid flow of the water body in the pool body, the sensor is easy to collide with other facilities in the pool or scrape to cause the damage of the sensor. Meanwhile, the sensor easily causes the connecting cable to be excessively stretched along with the movement of the water body, so that the connecting cable is damaged or even broken.
