The working principle is as follows: when needs carry out irrigation, push away this filter equipment for irrigation and water conservancy to the river course bank, the wheel that closes gyro wheel 4 is stopped, makes removal automobile body 3 firm. The lead screw motor that the lead screw on the lead screw guide rail is connected is opened, and the lead screw slider drives support cylinder body 32 and removes along removing automobile body length direction, removes to the other end of keeping away from push rod 5, and at this moment, cartridge filter mechanism 1 removes the automobile body outside, corresponds the river top setting in river course, and the delivery port on the frustum type bulge wall 13 of 11 one sides is strained through first, is connected to the pump body by the hydraulic pipeline. Through the regulation of regulation formula supporting mechanism 2, make cartridge filter mechanism 1 immerse the aquatic gradually downwards, specifically adjust support cylinder body 32, make its piston rod shrink, bracing piece 33 drives filtering mechanism 1 and descends gradually, filter screen piece 21 and branch 20 below the second section of thick bamboo 12 immerse the aquatic gradually, because supporting mechanism 2 rotates with cartridge filter mechanism through bending pole 35 and links to each other during the regulation, at the in-process that descends, the supplementary blowdown mechanism of constituteing by filter screen piece and branch plays certain counter weight effect, make the stable decline of whole cartridge filter mechanism, filter screen piece and branch play the cover to debris or pasture and water in the aquatic, the suppression effect, the jam to filtration pore 18 of second section of thick bamboo 12 bottom has been avoided, convenient follow-up filtration of drawing water. According to the condition that the first filter cylinder and the second filter cylinder are immersed in water, the air cylinder 36 can be continuously adjusted to enable the piston rod of the air cylinder to contract, and the connecting rod 34 hinged with the air cylinder drives the bending rod 35 to continuously descend, so that the first filter cylinder and the second filter cylinder are ensured to be immersed in water continuously. Because the lower section of the bending rod can be set to be telescopic, the first filter cartridge and the second filter cartridge can be conveniently immersed in water better, particularly, the lower section of the bending rod can be lengthened before the bending rod is adjusted to descend, and then the whole filter cartridge mechanism can be immersed in a river channel better through adjustment of the air cylinder 36. Opening the pump body, wherein river water is immersed into the cavities of the first filter cylinder 12 and the second filter cylinder 12 through the filter holes 18 of the second filter cylinder, is immersed into the first filter cylinder 11 through the filter holes of the first filter cylinder, and is finally discharged from the water outlet 14 on the frustum-shaped protruding wall 13; in the process, due to the arrangement of the rod body 19 on the second filter cylinder 12 and the filter holes 18 on the first filter cylinder and the second filter cylinder, impurities, garbage and the like in water are prevented from entering, the blockage of a water conveying pipeline and a pump body is reduced, and the irrigation efficiency is improved.

Example 2

As shown in fig. 6 to 8, the filtration apparatus for irrigation and water conservancy is the same as the filtration apparatus for irrigation and water conservancy of embodiment 1, except that the adjustable support mechanism 2 comprises a rotating disc seat 37 arranged on the top end surface of the moving vehicle body 3, a support cylinder 32 is supported and fixed on the rotating disc seat, a support rod 33 is fixedly connected to the top end of a piston rod of the support cylinder, one end of a connecting rod 34 is hinged to the top end of the support rod, one end of two bending rods 35 are fixedly connected to the other end of the connecting rod, and the other ends of the two bending rods are rotatably connected to the filter cartridge mechanism through a first bearing and a second bearing respectively; a cylinder 36 is hinged between the support rod and the connecting rod.

The working principle is as follows: this filter equipment theory of operation and process for irrigation and water conservancy are with embodiment 1 filter equipment's theory of operation, the institute is different because set up regulation formula supporting mechanism 2 and removal automobile body 3 into the horizontal rotation connected mode, can be when using, this regulation formula supporting mechanism 2 is rotated to direct level, make support cylinder body 32 through rotating disk seat 37 change to the outside of removing the automobile body, compare embodiment 1, the regulation mode is more nimble, the setting of electrical structure such as lead screw on the removal automobile body has also been reduced. When the filter cylinder mechanism 1 rotates to the outer side of the vehicle body of the mobile vehicle body through the adjusting type supporting mechanism 2, the supporting cylinder body 3 is continuously adjusted to enable the piston rod of the supporting cylinder body to contract, the filter cylinder mechanism is descended, and then the air cylinder 36 is adjusted to ensure that the first filter cylinder and the second filter cylinder are better immersed into the water body of the river channel.

Example 3

As shown in fig. 9 to 10, the filtration apparatus for irrigation and water conservancy is similar to the filtration apparatus for irrigation and water conservancy of embodiment 1, except that the adjustable support mechanism 2 includes a slide groove 38 provided on the top end surface of the movable body 3, and the slide groove 38 is provided along the longitudinal direction of the movable body.
