Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water quality detection equipment, and in particular to an intelligent discharge port water quality monitoring system. BACKGROUND

[0002] The intelligent discharge port is a modern discharge device, which is usually combined with an automatic opening and closing device such as a gate or a valve. With the advancement of modernization, more and more scenarios use the intelligent discharge port, such as factory sewage discharge ports, river sewage discharge ports, or domestic sewage discharge ports. The use of the intelligent discharge port can not only achieve timed and quantitative discharge, but also can sample and detect water quality.

[0003] The existing water quality monitoring equipment usually uses a detection rod to be inserted into the discharge port. When sewage is discharged, the detection rod can feedback information such as the PH value, temperature, and flow rate of the water quality. In order to better analyze the water quality, a water inlet is arranged near the discharge port to facilitate the sampling and detection of the water quality by the operator at regular intervals. However, the existing water sampling bottle has the above-mentioned shortcomings and deficiencies.

[0004] Because the diameter of the drain pipe is large, water samples at different depths need to be taken during sampling to detect the content and composition of the sediment in the water quality. The existing sampling bottle can only take a sample at a time, that is, after being lowered, a water sample at a certain depth is taken. Therefore, multiple sampling bottles need to be used to take water samples at different depths, which is complicated and time-consuming and labor-intensive.

[0005] In addition, the opening and closing of the existing sampling bottle under water is difficult to operate. When the water sample at a specific depth is taken, the water samples at the remaining depths will enter during the bottle collection process, thereby affecting the accuracy of the water sample at that depth.

Figure 5 As shown in the figure, a plurality of first water inlets 13 are arranged on the outer wall of the lower end of the bottle body 11, and the rotating cover 12 is rotatably arranged at the bottom of the bottle body 11. Specifically, the rotating cover 12 is provided with a rotating hole matched with the rotating clamping groove 21, and the rotating cover 12 is rotatably clamped at the lower end of the bottle body 11 through the cooperation of the rotating hole and the rotating clamping groove 21. The outer diameter of the part of the bottle body 11 provided with the first water inlet 13 is preferably rotatable with the inner diameter of the rotating cover 12, and the rotating gap is preferably controlled to be between 0.2-1mm. A plurality of second water inlets 14 are vertically arranged on the wall of the rotating cover 12 and are uniformly arranged around the circumference of the rotating cover 12. The second water inlets 14 are matched with the first water inlets 13. Specifically, when the rotating cover 12 is assembled with the bottle body 11, the second water inlets 14 on the rotating cover 12 are rotated to a state of being in communication with the first water inlets 13, and then rotated by an angle, so that the second water inlets 14 and the first water inlets 13 are staggered with each other, so that the inner cavity of the bottle body 11 forms a sealed cavity. When the above water inlets are in communication again, the inner cavity of the bottle body 11 becomes an open cavity again, and at this time, the water in the drain pipe 1 can enter the bottle body 11 through the water inlets.

At this time, when the sampling bottle 4 is lifted upward, the strong magnet 18 is always adsorbed by the magnetic plate 101. The driving plate 15 is lifted upward relative to the bottle body 11 under the tension of the second pull rope 19, so as to achieve the lifting effect of the lifting plate 16. The second pull rope 19 is preferably arranged in four around the circumference of the driving plate 15, so as to keep the stability of the driving plate 15 when being lifted.
