Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.
[0024] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "first", "second" and similar words used in the patent application specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0025] like Figure 1 , Figure 2 As shown, a micro water sampling station for water quality detection according to an example of the utility model comprises an installation box 10 and various instrument devices of the micro water sampling station installed in the box, wherein the instrument devices comprise a pretreatment water distribution tank 20, a water sampling device 30 and a controller, wherein the water sampling device 30 adopts a double water sampling pump arranged in parallel. Compared with the problem in the prior art that a single pump is damaged and the water sampling station cannot work, the double water sampling pumps can be used alternately, thereby avoiding the problem that the micro water station stops working and causes losses due to pump failure.
[0026] In this embodiment, the installation box 10 has components of the built-in micro water station.
[0027] Furthermore, the installation box 10 is made of anti-corrosion and anti-rust material, such as the installation box 10 made of stainless steel.
[0028] Furthermore, a maintenance call button is installed on the outside of the installation box 10, and a protective cover is provided on the maintenance call button, which can prevent the maintenance call button from being pressed accidentally.
[0029] Furthermore, the interior of the installation box 10 can be arranged in layers, so that the instruments and devices are firmly installed and scientifically distributed.
[0030] Furthermore, an electric control box is also provided in the installation box 10 to provide power to various instruments and devices.
[0031] In this embodiment, the pretreatment water distribution tank 20 is installed on the upper layer of the installation box 10. The pretreatment water distribution tank 20 is provided with a water inlet pipe 34 and a drainage pipe. The drainage pipe leads to the water quality detector and is provided with a solenoid valve. A liquid level sensor is provided in the pretreatment water distribution tank 20.
[0032] In this embodiment, the water sampling device 30 includes a sampling tube 33, which is connected to the input end of the first sampling pump 31 and the input end of the second sampling pump 32 through branch pipes. The output ends of the first sampling pump 31 and the second sampling pump 32 are connected to the water inlet pipe 34. The first sampling pump 31 and the second sampling pump 32 are both provided with sensors; and a controller, which linearly connects the liquid level sensor, the solenoid valve, the first sampling pump 31 and the second sampling pump 32.
[0033] Specifically, the liquid level sensor is connected to the controller, and the controller uses a software logic program to respond to the signal output by the liquid level sensor. When the water level in the pretreatment water distribution tank 20 has not reached the minimum water level, the controller controls the sampling pump of the sampling device to collect and input water samples. When the water level in the pretreatment water distribution tank 20 reaches the maximum water level, the sampling device stops working.
[0034] Furthermore, the drain pipe is connected to the drain port at the upper part of the pretreatment water distribution tank 20, and an overflow port is provided below the drain port, and a branch is provided in the drain pipe to connect to the overflow port. The overflow pipe and the drain pipe use the same pipeline, which makes the pipeline setting more concise and avoids redundant pipelines; at the same time, the overflow port also avoids the problem of overflow caused by excessive water level in the pretreatment water distribution tank 20; the drain port is provided at the upper part of the pretreatment water distribution tank 20, which is convenient for the water quality detector to use the supernatant of the water sample.
[0035] Furthermore, the water inlet pipe 34 may also include a first water inlet pipe 21 and a second water inlet pipe 22, the first sampling pump 31 is arranged on the first water inlet pipe 21, and the second sampling pump 32 is arranged on the second water inlet pipe 22. The first water inlet pipe 21 connects the sampling pipe 33 and the first water inlet of the pretreatment water distribution tank 20, and the second water inlet pipe 22 connects the sampling pipe 33 and the second water inlet of the pretreatment water distribution tank 20.
[0036] Furthermore, the first sampling pump 31 and the second sampling pump 32 are dual-purpose micro water pumps for water and air.
[0037] Furthermore, the first sampling pump 31 and the second sampling pump 32 are connected to a time circuit breaker, and the time circuit breaker is connected to the controller. The time circuit breaker can be used to control the sampling process. Under the action of the controller, the first sampling pump 31 and the second sampling pump 32 are used alternately at regular intervals. In this embodiment, the first sampling pump 31 and the second sampling pump 32 are used alternately every 15 minutes, and the samples enter the pretreatment water distribution bucket. After the sampling technique, the water sample is physically settled in the pretreatment water distribution tank 20.
[0038] Furthermore, the controller can also be connected to a remote control terminal, which includes a central control platform and an APP to facilitate remote control by staff.
[0039] Specifically, in actual work, the controller can select any one of the two pumps to run alone, or can select the two to run alternately or both pumps to run together. In particular, when one of the pumps fails, the relevant data is uploaded to the remote control end, so that the remote control end controls the other pump to continue working. The failed pump can wait for the micro water station to stop working, be removed and repaired, and then reinstalled after repair. The whole process will not affect the normal operation of the micro water station.
[0040] Furthermore, the micro water sampling station has a length of 900 mm, a width of 900 mm, and a height of 1900 mm, and is small in size and easy to place and transport.
[0041] The operation process of the micro water sampling station in this embodiment is as follows: the staff first carries the micro water sampling station to the detection location, the staff puts the sampling tube 33 into the water source to be detected, and the operator issues a running command. The water of the water source to be detected is pumped by the sampling pump to the pretreatment water distribution tank 20. After physical sedimentation and other treatments in the tank, the upper clear liquid is transmitted to the water quality detector through the drainage pipe for detection.
[0042] In summary, the technical solution of this application has the following beneficial effects:
[0043] 1. The present application designs two pumps connected to the pipeline in parallel on the device for collecting water samples. The two pumps can operate alternately. Any one of the pumps can independently support the normal operation of the micro water station. When one of the pumps encounters an obstacle, the other pump can ensure the normal operation of the micro water station, thus avoiding the problem of the micro water station stopping working and causing losses due to pump failure.
[0044] 2. The installation box 10 of the present application is designed in layers, and the pipeline setting is simple, which overcomes the problems of complex and redundant pipeline setting in the prior art.
[0045] 3. This application has a simple structure and occupies a small area, so it has no special requirements for terrain and has strong applicability.
[0046] The above are merely exemplary embodiments of the present application and are not intended to limit the protection scope of the present application. The protection scope of the present application is determined by the appended claims.
