Fig. 2 is the structural schematic diagram of flow divider.
Fig. 3 is the sectional view along A-A in Fig. 2.
Specific implementation mode
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
As shown, the present embodiment provides a kind of water quality monitoring system based on unmanned boat, including unmanned boat 1, described
At least one set of detection unit is provided on unmanned boat 1, the detection unit includes water gathering tube 21, water acquisition pump 22, is connected to water acquisition
The flow divider 23 of pipe 22 and four test chambers 24 for being connected to flow divider 23, one kind is respectively arranged in each test chamber 24
Sensor 25.
The flow divider 23 includes the valve body 231 for being internally provided with chamber 230, and a circle is provided in the chamber 230
The axial location of columnar spool 232, the spool 232 is equipped with a shaft 233, and the shaft 233 is installed on a motor 234
Power output end, the spool 232 can rotate under the drive of the motor 234；It is equal in the circumferential direction of the spool 232
Even three groove 232a that arc is distributed with；Water outlet 235 there are four being uniformly distributed in the madial wall of the chamber 230；Each
A guide rod 236 is provided in the water outlet 235, the guide rod 236 is provided with one close to one end of the spool 232
Steel ball 237, a compressed spring 238 is sleeved on 236 outside of the guide rod and withstands the steel ball 237, and works as the steel ball 237
It can be pressed on water outlet 235 to close water outlet 235 when withstanding on the lateral wall of the spool 232, when the steel ball 237
Water outlet 235 can be left when in into groove 232a to which water outlet 235 is open-minded.
Due to uniformly distributed three grooves 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 be removed out of groove, to make four water outlets be all closed；It can also
Enough by rotary spool, wherein some steel ball is set to 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
It is more convenient to control Spool rotating.
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 the water acquisition pump, motor, sensor respectively.
