Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 4 and 5, the present embodiment provides a water quality monitoring apparatus including a sampling water tank, a water pump 7, a liquid level detection part 5, and a controller 8. The sampling bucket comprises a bucket body 1, a sampling pipeline 4 communicated with the bucket body 1 and a water quality detection sensor 3 arranged in the bucket body 1; the water pump 7 is communicated with the sampling pipeline 4 so as to convey a water sample to be detected into the barrel body 1; the liquid level detection part 5 is arranged in the barrel body 1 to detect the liquid level of a water sample in the barrel body 1; the controller 8 is in signal connection with both the liquid level detection part 5 and the water pump 7 so as to control the water pump 7 to be turned off when the liquid level of the barrel body 1 is higher than a preset height.
In this embodiment, the controller 8 can close the water pump 7 when the liquid level detection part 5 detects that the liquid level of the water sample reaches the predetermined height, which is favorable for improving the problem that the water sample in the prior art may overflow the water bucket accidentally.
The liquid level detection part 5 comprises a first probe 51, and the first probe 51 is in signal connection with the controller 8 to transmit a signal to the controller 8 when the liquid level reaches a predetermined height.
The liquid level detection part 5 comprises a second probe 52, the position of the second probe 52 is higher than that of the first probe 51, and the second probe 52 is in signal connection with the controller 8 so as to control the water pump 7 to be switched off after the second probe 52 senses a water sample.
The liquid level detection part 5 further comprises a third probe 53, and the third probe 53 is arranged at the bottom of the barrel body 1.
In this embodiment, a set of liquid level detection part 5 with 3 probes of low, medium and high water levels, of type JYB-714, and a liquid level relay (see fig. 4) are provided at the bottom of the sampling water tank to detect the liquid level of the sampling water tank. When the sampling is triggered, when the water level exceeds 300mm due to the failure of the control system or the abnormality of the water pump 7 and continuously rises, and a water sample contacts the first probe 51 (namely the liquid level rises to about 320mm of the height of the sampling barrel), the liquid level relay sends a pulse signal to the input point DI1 of the water pumping system control module, the water pumping system control module outputs the pulse signal from the DO3 to the relay of the water pump, the water pump 7 stops working, and the water taking is finished. The second probe 52 is used as a backup probe, when the first probe 51 is damaged or fails due to other faults, the water level will continue to rise to the second probe 52 (i.e. the liquid level rises to about 350mm of the height of the sampling barrel), at this time, the liquid level relay sends a pulse signal to the input point DI1 of the pumping system control module, and the pumping system control module outputs a pulse signal from the DO3 to stop the operation of the water pump (see FIG. 5).
In this embodiment, the controller 8 is an original water pumping system control module.
The water quality monitoring device further comprises a drain pipe 6, and the drain pipe 6 is positioned in the barrel body 1 so as to discharge a water sample in the barrel body 1, wherein the water sample is higher than an inlet of the drain pipe 6.
In order to avoid the extreme condition that the water pumping process cannot be stopped due to the sequential failure of the water pumping control system, the water pump 7, the liquid level detection part 5 and the liquid level relay or other factors, a standby water drainage pipe 6 is added. A hole with the diameter of 1 inch (the outer diameter is 32mm, the inner diameter is 25mm) is additionally arranged at the bottom of the sampling water bucket, a drain pipe 6 with the height of 355mm is arranged in the sampling water bucket, and the drain pipe is connected to a water intake of the middle water pool after being butted with a pipeline at the bottom of the sampling water bucket and then is connected to the water intake of the middle water pool. When the liquid level continuously rises to exceed 355mm of the height of the sampling barrel due to system or hardware faults, the water sample flows back to the middle water pool from the standby drain pipe 6.
The drain pipe 6 is vertically arranged in the barrel body 1, and the inlet of the drain pipe 6 is positioned at the upper end of the drain outlet. The inlet of the drain pipe 6 is higher than a predetermined height.
Be provided with the hole with drain pipe looks adaptation on the diapire 9 of staving 1, drain pipe 6 extends to the outside of staving 1 by the through-hole.
