DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0023] An air well washing structure of a precipitation well, such as Figure 1 and Figure 2 , comprises a mounting ring 2 placed on the ground at the well mouth of the precipitation well 1 and a well washer body 3 located in the precipitation well 1, the well washer body 3 is provided with a pull rod 4, the end of the pull rod 4 away from the well washer body 3 extends vertically upward out of the precipitation well 1, and the mounting ring 2 is provided with a pushing piece for driving the pull rod 4 to move vertically up and down.

[0024] As Figure 1 and Figure 2When the well washer body 3 needs to be pulled up, only the pusher on the mounting ring 2 is used to vertically move the pull rod 4 up and down, at this time the well washer body 3 will move with the pull rod 4, at this time the pulling up of the well washer body 3 can be realized, without manually pulling up the well washer through the lifting rod, saving manpower and being convenient to use.

[0025] The well washer body 3 and the pull rod 4 can be the well washer body and the lifting rod in the mud return spraying type well washer of claim CN201820941198.7, which will not be described here.

[0026] As Figure 3 , the bottom end of the mounting ring 2 is provided with a support disc 5 in contact with the ground through an extension rod, the number of the extension rods is several, and each extension rod is uniformly distributed along the circumference of the mounting ring 2, the extension rod includes a screw rod 6 arranged at the bottom end of the mounting ring 2 and a threaded cylinder 7 threadedly connected to the screw rod 6, and the support disc 5 is arranged at the bottom end of the threaded cylinder 7, at this time the support disc 5 is below the screw rod 6, the purpose of this arrangement is that when the ground on which the mounting ring 2 is placed is uneven, the threaded cylinder 7 is rotated, at this time the support disc 5 is away from or close to the mounting ring 2 through the cooperation of the threaded cylinder 7 and the screw rod 6, until each support disc 5 is in contact with the ground, at this time the mounting ring 2 can be applied to uneven ground through each extension rod and the support disc 5, which is simple and convenient to use.

[0027] As Figure 3 , the pusher includes a threaded barrel 8 threadedly connected to the top end of the pull rod 4 and an inverted U-shaped mounting bracket 9 arranged at the top end of the mounting ring 2, the threaded barrel 8 is vertically located in the mounting bracket 9, and the top end of the threaded barrel 8 is rotatably connected with a rotating disc 10, the mounting bracket 9 is provided with an electric cylinder 12, and one end of the piston rod of the electric cylinder 12 is fixedly connected with the top end of the rotating disc 10. When the pull rod 4 needs to be vertically moved, only the threaded barrel 8 is threadedly connected to the pull rod 4, and then the electric cylinder 12 is opened, the piston rod of the electric cylinder 12 pushes the rotating disc 10 to vertically move the threaded barrel 8, at this time the pull rod 4 will vertically move with the threaded barrel 8, realizing the pulling up of the pull rod 4 and the well washer body 3.

[0028] As Figure 3The top end of the mounting frame 9 is horizontally provided with a sliding groove 13, a sliding block 14 is horizontally and slidably connected in the sliding groove 13, a screw rod 15 is rotationally connected between the front and rear groove walls of the sliding groove 13, one end of the screw rod 15 penetrates through the sliding block 14 and is threadedly connected with the sliding block 14, a hand lever 16 is arranged on the mounting frame 9 and used to drive the screw rod 15 to rotate, the electric cylinder 12 is arranged at the top end of the sliding block 14, and the threaded barrel 8 is located below the sliding block 14. At this time, the piston rod of the electric cylinder 12 penetrates through the sliding block 14 and is connected with the rotating disc 10, the piston rod of the electric cylinder 12 is dislocated with the screw rod 15. The purpose of this arrangement is that the screw rod 15 is driven to rotate by the hand lever 16. At this time, since one end of the screw rod 15 penetrates through the sliding block 14 and is threadedly connected with the sliding block 14, when the screw rod 15 rotates, the sliding block 14 is pushed to move horizontally in the sliding groove 13. At this time, the electric cylinder 12, the rotating disc 10 and the threaded barrel 8 move along with the sliding block 14. At this time, the alignment of the pull rod 4 and the threaded barrel 8 is facilitated. After alignment, the top end of the pull rod 4 is screwed into the threaded barrel 8. During the vertical movement of the pull rod 4 under the action of the electric cylinder 12, the screw rod 15 is driven to rotate by the hand lever 16, and the sliding block 14 slides in the sliding groove 13, so that the horizontal position of the pull rod 4 and the pull well washer body 3 in the dewatering well 1 is adjusted, and the dewatering well 1 is washed by the pull well washer body 3.

[0029] As Figure 3 and Figure 4 The top end of the mounting ring 2 is coaxially provided with an annular sliding rail 17, and two sliding blocks 18 are slidably connected on the sliding rail 17 in the circumferential direction of the sliding rail 17. The top end of one of the sliding blocks 18 is provided with a threaded groove 21, and a bolt 19 is threadedly connected in the threaded groove 21. The bottom end of the bolt 19 abuts against the top end of the sliding rail 17. The mounting frame 9 is arranged at the top ends of the two sliding blocks 18. The purpose of this arrangement is that when the mounting ring 2 is coaxial with the dewatering well 1, the pull rod 4 is connected with the threaded barrel 8, and the pull rod 4 is dislocated with the dewatering well 1, the bolt 19 can be loosened, and then the mounting frame 9 drives the sliding blocks 18 to slide on the sliding rail 17 in the circumferential direction of the mounting ring 2. At this time, the horizontal position of the pull rod 4 and the pull well washer body 3 in the dewatering well 1 can be adjusted. The use is simple and convenient.

[0030] As Figure 2 and Figure 3 The top end of the mounting frame 9 is inclined downwardly and provided with a reinforcing rod 20, and the bottom end of the reinforcing rod 20 is connected with the vertical edge of the mounting frame 9. The purpose of this arrangement is that the reinforcing rod 20 can reduce the bending of the horizontal edge of the mounting frame 9. The reinforcing rod 20 does not affect the horizontal movement of the sliding block 14, the electric cylinder 12, the threaded barrel 8 and the pull rod 4.

[0031] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
