[0018] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0019] As a water intake device for an online water quality monitoring station of a rain-source mountain river of the utility model, as Figure 1-2As shown in the figure, this embodiment provides a water intake device for an online water quality monitoring station in a rain-source mountain river channel, including a water storage tank 2. A float valve 7 is bolted inside the water storage tank 2. A flushing assembly 9 is installed on the surface of the water storage tank 2. The flushing assembly 9 includes a flushing drain pipe 3, a flushing water inlet gate 5, a flushing water drain gate 6, and a flushing inlet pipe 8. Under the action of the float valve 7, the water level in the water storage tank 2 can be monitored, so as to control the water intake pump and drain the excess water stored in the water storage tank 2.
[0020] In some preferred embodiments, as Figure 1 and Figure 2 shown, the left end of the flushing water drain gate 6 is fixedly communicated with the right side of the water storage tank 2, and the left end of the flushing drain pipe 3 is fixedly communicated with the right end of the flushing water drain gate 6.
[0021] In some preferred embodiments, as Figure 1 and Figure 2 shown, the right end of the flushing water inlet gate 5 is fixedly communicated with the left side of the water storage tank 2, and the right end of the flushing inlet pipe 8 is fixedly communicated with the left end of the flushing water inlet gate 5.
[0022] In some preferred embodiments, as Figure 1 and Figure 2 shown, suction pipe orifices 4 are provided on both the front and rear sides of the water storage tank 2. An intake filter 1 is bolted to the rear side of the water storage tank 2. The aperture of the filter of the intake filter 1 should ensure that most of the floating scum and stones in the river water can be intercepted, so as to prevent stones from entering the interior of the water storage tank 2. Through the suction pipe orifices 4, it is used to connect the valves and the water intake pump, so that water can enter the water storage tank 2 for the water intake pump to suck.
[0023] As Figure 1 shown, the present utility model is particularly suitable for installation under the river bottom. When in use, the water storage tank 2 is divided into an intake working condition, a water suction working condition, and a drainage working condition. In the intake working condition, the flushing water inlet gate 5 and the flushing water drain gate 6 are closed, and the water level in the water storage tank 2 is monitored through the float valve 7. When the water level in the water storage tank 2 reaches the specified height and the sampling time is reached, the water suction working condition starts. In the water suction working condition, water is taken from the water storage tank 2 through an external water intake pump, and the liquid level in the water storage tank 2 decreases. Through the monitoring of the float valve 7, when the liquid level in the water storage tank 2 decreases to the specified height, the water intake pump stops sucking water. When the liquid level reaches the specified height and the water storage time reaches the specified time, the drainage working condition starts. The flushing water inlet gate 5 and the flushing water drain gate 6 are opened, so that the flushing water enters the water storage tank 2 through the flushing inlet pipe 8 to flush it, so that the accumulated water and sediment inside the water storage tank 2 are discharged through the flushing drain pipe 3, so as to update the water sample in the water storage tank 2, ensuring that the online water quality monitoring station can obtain a sufficient amount of qualified water samples according to the established sampling frequency throughout the year.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
