Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1, 2, 3 and 4, a PVC-U drain pipe includes a drain pipe body 1, a chute 2 is provided on an inner wall of the drain pipe body 1 in a vertical direction, a top end of the chute 2 penetrates through a top end of the drain pipe body 1, a bottom end of the chute 2 does not penetrate through a bottom end of the drain pipe body 1, a dirt removing rod 3 is provided inside the chute 2, and the dirt removing rod 3 can slide in the chute 2. The bottom end of the sliding groove 2 is provided with a spring through hole 4, a spring 5 is arranged in the spring through hole 4, and the spring 5 is made of stainless steel metal. The spring 5 top is equipped with the pole of decontaminating 3, 5 one end of spring is fixed to be set up the bottom of spring through-hole 4, the other end with the bottom fixed connection of pole of decontaminating 3. Be equipped with a plurality of first stoppers 6 on the 1 inner wall of drain pipe body, 6 cross-sectional shape of first stopper are fan-shaped. The dirt removing rod 3 is located between the first limiting block 6 and the inner wall of the sliding groove 2. The first limiting block 6 is fixed on the inner wall of the drain pipe body 1 through one of the two modes of integral forming and bolt fixing. Preferably, the first limiting block 6 and the drain pipe body 1 are integrally formed. The first limiting block can limit the moving position of the dirt removing rod 3, and the dirt removing rod 3 can move back and forth in the vertical direction.

The trash cleaning rod 3 is of a vertical rod-shaped structure, a plurality of grooves 7 are formed in the side face of the trash cleaning rod in the vertical direction at equal intervals, one ends of oblique rods 8 are arranged in the grooves 7, and the oblique rods 8 are arranged in the grooves 7 in a hinged mode. The water flow is discharged from top to bottom, and the inclined rod 8 is inclined downwards under the impact of water and the action of the gravity of the inclined rod 8. Because the inclined rod 8 inclines downwards, the sewage discharge effect of the drain pipe body 1 is not influenced.

The first limiting block 6 is located below the groove 7, and the second limiting block 9 is arranged above the groove 7. Second stopper 9 is L shape, and its both ends are end a9.1 and end b9.2 respectively, end b9.2 is located end a9.1 below, end a9.1 vertical fixation sets up on the pole 3 lateral walls of decontaminating, second stopper 9 with the pole 3 integrated into one piece of decontaminating. When the drain pipe body 1 is blocked, the dirt removing rod 3 moves downwards, due to the interaction of force, the free end of the inclined rod 8 is subjected to the upward acting force of a blocking object, the inclined rod 8 starts to rotate upwards by taking the hinged part as the circle center, and the second limiting block 9 can limit the rotation of the inclined rod 8.

The top end face of the drain pipe body 1 is provided with a concave part 10 beside the sliding groove 2, the top end of the dirt cleaning rod 3 is provided with a third limiting block 11, and the third limiting block 11 is matched with the concave part 10 in shape. The third stopper 11 can prevent the 3 slides of pole of decontaminating inside the drain pipe body 1 for the people can't operate pole of decontaminating 3. The top end of the third limiting block 11 is fixedly provided with a metal ring, and the dirt removing rod 3 can be conveniently moved by people through the metal ring.

Example 1, when used: when the drain pipe body 1 is blocked, the metal ring is hooked upwards by using a metal wire or a hook, and the dirt removing rod 3 moves upwards. Because the pole of decontaminating 3 is connected with spring 5 the effect of spring 5 pulling force is down the pole 3 downstream of decontaminating, repeated operation afterwards for the pole 3 back and forth movement of decontaminating can dredge the debris of jam under the effect of diagonal pole 8.

Example 2, when used: when the tension of the spring 5 is not enough to pull the trash cleaning rod 3, and further not enough to enable the trash cleaning rod 3 to move downwards, the trash cleaning rod 3 can be pushed and pulled manually, and the trash cleaning rod 3 is guaranteed to move back and forth in the sliding groove 2.

The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
