As shown in Fig. 2, in the present embodiment, installation trunnion 309 is respectively set in the both ends of cleaning pipe 203, to be pacified
Dress.
Embodiment 2
As another embodiment, the main distinction of the present embodiment and above-described embodiment 1 is, in the present embodiment,
The both ends of cleaning pipe 203 are respectively first end 205 and second end 206, and sewage draining exit 303 is set to first end 205, and drive module is set
It is placed in second end 206, the side wall of cleaning pipe 203 is provided with water inlet 310 at the position of second end 206, as shown in figure 4,
Water inlet 310 is for being connected to water supply pipe 202.
Embodiment 3
The present embodiment and the main distinction of embodiment 1 be, in the present embodiment, drive module using motor 307,
Cleaning rod 301 is driven to rotate using motor 307, to realize cleaning function.
As shown in figure 5, in the present embodiment, one end that may be mounted at cleaning pipe 203 of motor 307 is (as mentioned before
Second end 206), the output shaft of motor 307 is connected with cleaning rod 301, and on-off module can use valve 304, and valve 304
It is set to the sewage pipe 305 being connected with sewage draining exit 303；When needing washer jet 204, operation maintenance personnel can open valve
Door 304, while starting motor 307, motor 307 drives cleaning rod 301 to rotate, and real by bristle 302 in the course of rotation
Now to the cleaning of 203 inner wall of cleaning pipe and nozzle 204, allow be gathered in 204 impurity of nozzle under the action of bristle 302 from
Nozzle 204 is opened, the impurity for leaving nozzle 204 can be discharged under the drive of water flow from sewage draining exit 303 via sewage pipe 305, from
And can effectively solve the problems, such as that nozzle 204 is easy and block, is difficult cleaning of, so that grid is constantly in normal operating condition；Clearly
It washes after finishing, operation maintenance personnel closes valve 304 and motor 307, entire cleaning process are very convenient, efficient.
Embodiment 4
In a kind of back purge system with self-cleaning function provided by the present embodiment, on-off module includes sealing block
311, as shown in fig. 6, sealing block 311 is arranged in nozzle 204 and sewage draining exit at the beginning (when not cleaning to nozzle 204)
Between 303, sealing block 311 can effectively block the connection of sewage draining exit 303 Yu cleaning pipe 203, so that rushing into cleaning pipe 203
Wash water can only be sprayed from nozzle 204；As shown in fig. 7, sealing block 311 can be synchronous with cleaning rod 301 in washer jet 204
It rotates and moves, and realize the connection of sewage draining exit 303 and cleaning pipe 203, i.e., during rotation, sealing block in moving process
311 position can change, so that sewage draining exit 303 is connected to cleaning pipe 203, so that in cleaning pipe 203 after cleaning
Sewage can be discharged from sewage draining exit 303；After having cleaned (or after completing primary cleaning), sealing block 311 divides with cleaning rod 301
Initial position is not returned to, so that the channel between sewage draining exit 303 and cleaning pipe 203 disconnects, to be cleaned next time.
As is seen in fig. 6 or fig. 7, in a kind of preferred embodiment provided in this embodiment, on-off module further include cylinder 312,
