Description
Technical field
The present invention relates to a kind of flow dividers for water quality monitoring system, belong to water quality monitoring technical field.
Background technique
Water quality monitoring is type, the concentration and variation tendency of each pollutant of pollutant in monitoring and measurement water body, comments
The process of valence water quality condition.Monitoring range is very extensive, including is not contaminated and contaminated natural water (river, river, lake, sea
And underground water) and various industrial water drainages etc..Main monitoring project can be divided into two major classes: one kind is reflection water quality condition
Overall target, such as temperature, coloration, turbidity, pH value, conductivity, suspended matter, dissolved oxygen, COD and biochemical oxygen demand (BOD)；
Another kind of is some noxious materials, such as phenol, cyanogen, arsenic, lead, chromium, cadmium, mercury and organic agricultural chemicals.For objective appraisal rivers and sea
The situation of foreign-water matter needs the measurement for carrying out flow velocity and flow in addition to above-mentioned monitoring project sometimes.At present in water quality monitoring usually
Water sampling and water quality detection are carried out using to unmanned boat, the water in waters is collected by ship by the sampling pump on unmanned boat
On test chamber in, then the sample water in test chamber is detected by the sensor on unmanned boat, such as Chinese patent
Document CN207510670U discloses a kind of unmanned boat for water quality monitoring.Water quality detection sensor is all largely electrification
Sensor is learned, will appear the consumption of the chemical substance in sensor in long-time use process, so that sensor accuracy
Decline, therefore need to replace sensor in use for some time.And on existing unmanned boat, due to all kinds of sensings
Device is unified to be arranged in test chamber, therefore generates consumption to each sensor after sample water enters in test chamber.However
Certain waters do not need to be monitored the various data of water quality, it is only necessary to acquire certain class water quality data, such as the ph of water quality
Value, and this has resulted in the unnecessary loss of other sensors.Therefore each sensor can be provided separately within to an inspection
It surveys intracavitary, and can select to inject sample water into some or certain some test chambers as needed to obtain corresponding water quality
Data, this just needs to flow in corresponding test chamber using to flow divider by the moisture that water pump pumps is adopted.
Summary of the invention
Therefore, the purpose of the present invention is to provide a kind of tool, there are four water outlets, and can be from any single water outlet
The flow divider for water quality monitoring system drained outward.
To achieve the goals above, a kind of flow divider for water quality monitoring system of the invention, including be internally provided with
The valve body of chamber, is provided with a columned spool in the chamber, and the axial location of the spool is equipped with a shaft, institute
The power output end that shaft is installed on a motor is stated, the spool can rotate under the drive of the motor；In the spool
Circumferential direction on be evenly distributed with three grooves of arc；Water outlet there are four being uniformly distributed in the inner sidewall of the chamber；Each
A guide rod is provided in the water outlet, one end close to the spool of the guide rod is provided with a steel ball, a compression
Spring pocket is on the outside of the guide rod and withstands the steel ball, and the energy when the steel ball is withstood on the lateral wall of the spool
It is enough pressed on water outlet to close water outlet, water outlet can be left when the steel ball enters in groove thus by water outlet
It is open-minded.
The marginal position of the water outlet is provided with sealing ring.
By adopting the above technical scheme, the flow divider for water quality monitoring system of the invention, is able to drive valve by motor
Core is rotated to different station, and so as to carry out switching water discharging on four water outlets, and structure is relatively simple, not rapid wear
It is bad.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for having used the water quality monitoring system of flow divider of the present invention.
Fig. 2 is the structural schematic diagram of flow divider of the invention.
Fig. 3 is the sectional view along A-A in Fig. 2.
Specific embodiment
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, flow divider of the invention can be used in water quality monitoring system, which includes nobody
Ship 1, is provided at least one set of detection unit on the unmanned boat 1, the detection unit include water gathering tube 21, adopt water pump 22,
It is connected to the flow divider 23 of water gathering tube 22 and is connected to four test chambers 24 of flow divider 23, in each test chamber 24 respectively
It is provided with a kind of sensor 25.
As shown in Figure 2,3, flow divider 23 of the invention includes the valve body 231 for being internally provided with chamber 230, in the chamber
A columned spool 232 is provided in 230, the axial location of the spool 232 is equipped with a shaft 233, the shaft 233
It is installed on the power output end of a motor 234, the spool 232 can rotate under the drive of the motor 234；In the valve
Three groove 232a of arc are evenly distributed in the circumferential direction of core 232；There are four being uniformly distributed in the inner sidewall of the chamber 230
Water outlet 235；A guide rod 236, the close spool 232 of the guide rod 236 are provided in each water outlet 235
One end be provided with a steel ball 237,238 sets of a compressed spring is in 236 outside of guide rod and withstands the steel ball 237,
And it can be pressed in when the steel ball 237 is withstood on the lateral wall of the spool 232 on water outlet 235 thus by water outlet 235
Closing can leave water outlet 235 when the steel ball 237 enters in groove 232a to which water outlet 235 is open-minded.
Due to three grooves uniformly distributed in the circumferential direction of spool, and four water outlets and steel are evenly distributed on the side wall of chamber
Ball, therefore by rotational valve core, four steel balls can be made to remove out of groove, so that four water outlets be made to be all closed；It can also
Enough by rotary spool, make wherein some steel ball enter in groove, excess-three steel ball is then outside groove, so that only one
Water outlet drains outward.Meanwhile above structure makes spool stress more balanced, overall structure is also relatively stable, passes through motor
Control valve core rotation is more convenient.
The marginal position of the water outlet 235 is provided with sealing ring 239.
The unmanned boat 1 further includes controller 3, and the controller 3 is connected with water pump, motor, the sensor adopted respectively.
The end of the water gathering tube 21 is provided with filter screen 210.
In the water quality monitoring system, Spool rotating is able to drive to different station, so as at four by motor
Switching water discharging is carried out on water outlet, so that sample water is entered different test chambers and is detected.Therefore, when only needing in sample water
A certain item index when being detected, then corresponding water outlet can be made to open with rotary spool, remaining water outlet is closed, sample water
It then can only enter in corresponding test chamber and be detected.
Obviously, above-described embodiment is only intended to clearly illustrate example, and does not limit the embodiments.For
For those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And obvious variation extended from this or change
It moves still within the protection scope of the invention.
