Embodiment 2
With reference to Fig. 6-8, the present embodiment further includes following characteristics on the basis of embodiment 1：It is water storage in the fire fighting truck ontology
Case, the water tank top are connected with the suction pump for adding water into water tank, and the water inlet end of suction pump passes through delivery hose
It is connected with filter assemblies, the filter assemblies are floated on the water surface in river or lake and drawn water.
The filter assemblies include float 91, are fixedly connected on the connection cover 92 of float lower end, are connected under connection cover
The cylinder ceramic element 93 of the entirety at end, and be set in ceramic element periphery brushing during moving up and down
The brush body 94 of ceramic element outer wall plug.
The side of the connection cover is fixedly connected with water outlet pipe 921, and the side wall of the water outlet pipe forms pipe fitting
A922, the water outlet pipe are connected to the inside of ceramic element.
The upper end of the ceramic element is fixedly connected with the filter core top connection 931 of the annular of plastic material, filter core top connection
It is connected through a screw thread between connection cover lower end；The lower end of the ceramic element is fixedly connected with to close ceramic element lower end
Plastic material filter core lower contact 932；The diameter of the filter core lower contact is more than the diameter of ceramic element, is connect under the filter core
The periphery that head upper end is located at ceramic element is fixedly connected with multiple longitudinally disposed guide rods 933, and each guide rod is along ceramic element
Circumferentially equidistant arrangement.
The brush body includes to have entirety in circular ring shape and the brush holder 941 of lower ending opening, is sealedly connected on brush holder lower end
The brush lid 942 of annular, sealing are slidably mounted on the piston 943 of the annular in brush holder, and in piston upper end and brush holder
Spring 944 between top；The inner circumferential of the brush holder is equably connected with to brush the bristle of ceramic element outer wall plug
9412；Side on the brush holder close to upper end forms pipe fitting b9411, passes through between the pipe fitting b and pipe fitting a
Hose is connected；It is filled with liquescent gas in space in the brush body between piston and brush lid；The easy liquefaction
Gas can be freon.
It is described brush lid outer diameter be more than brush holder outer diameter, it is described brush cover form it is corresponding respectively with each guide rod
The pilot hole 9421 being slidably connected.
The buoyancy value of the float in water is more than 1.2 times of filter assemblies overall weight.
When negative pressure value in the ceramic element is increased above the elastic force of spring, hose, water outlet pipe, company are passed sequentially through
The conducting of lid is connect to also form negative pressure with the top for being located at piston in the brush holder being connected inside ceramic element so that piston pressure
Contracting spring moves up.
When the piston is moved to brush body inner top extreme position under the action of negative pressure, the buoyancy of brush body is more than brush body
The gravity of itself so that brush body moves from bottom to top along guide rod；When the piston is moved to bottom limit position in brush body,
Brush body is more than the buoyancy of brush body together with the gravity of the water in brush body so that brush body moves from top to bottom along guide rod.
It connects and is connected with fluid pressure sensor on the pipeline of the suction pump water inlet end, when fluid pressure sensor detects
To negative pressure value（Absolute value）It is determined as that ceramic element outer wall blocks when being greater than the set value, the output power for controlling suction pump at this time is handed over
Alternately increase, reduce a period of time（2-5min）；When the output power of suction pump increases, make to be connected with suction pump water inlet end
Brush body in formed negative pressure, when the piston is moved to brush body inner top extreme position under the action of negative pressure, the buoyancy of brush body is big
In the gravity of itself of brush body so that brush body moves from bottom to top along guide rod, to make bristle carry out ceramic element outer wall
Scrub；When the output power of suction pump reduces, the negative pressure in brush body being connected with suction pump water inlet end reduces, and piston is in bullet
Spring is replied under force effect, and bottom limit position in brush body is moved to, and brush body is more than the floating of brush body together with the gravity of the water in brush body
Power so that brush body moves from top to bottom along guide rod, to make bristle scrub ceramic element outer wall again.If by
After dry scrub, ceramic element is made to restore normal filtration condition.
Through this structure, the movement of brush body is driven without designing extra driving part, only passes through system itself
Entrained suction pump realizes the function that ceramic element cleans automatically.
Compared to the Chinese patent literature that document number is CN105688478A, although also achieving automatic brushing ceramic filtering
The function of core, but it is only applicable to the structure that ceramic element is encapsulated in a closing shell, when ceramic element is needed as this hair
It is just not suitable for when being equally in open environment in bright.Further, by changing brush body overall weight in the present invention
It is allowed to move up and down with the difference of buoyancy to realize the action of scrub, it is ingenious in design, and the water for passing in and out brush body is after filtering
Water, will not be hindered by impurity in piston moving process, service life and non-maintaining time significantly extend.
