Example 1

As shown in figures 1-6, the built-in drainage pipeline with the detachable large-hole intercepting filter screen comprises a pipeline 3 and a filter screen 1, wherein a plurality of fixing hooks 4 are uniformly arranged on the inner walls of the two ends of the outlet and the inlet of the pipeline 3 along the circumferential direction respectively, and the fixing hooks 4 are connected with the filter screen 1. Pipeline 3 adopts PVC-UH to make, and fixed hook 4 welds in pipeline 3 inner wall, and fixed hook 4 is located 3/20 departments at pipeline 3 full length both ends to make installation that can be convenient through fixed hook 4 with demolish filter screen 1, compare the filter screen 1 that sets up in the middle of the pipeline, can be comparatively convenient dismantle filter screen 1, clear up or retrieve and block the thing, simultaneously effectual daily wearing and tearing and destruction that have reduced.

In the preferred scheme, fixed hook 4 includes parallel arrangement's fixed block 401 and stopper 403, and fixed block 401 is used for fixed with 3 inner walls of pipeline, is connected with connecting block 402 between fixed block 401 and the stopper 403, and fixed block 401, connecting block 402, stopper 403 and the combination of 3 inner walls of pipeline form joint portion 404, and joint portion 404 is used for being connected with filter screen 1. With this structure, the dimensions and the thickness of the retainer 101 of the catching portion 404 are matched so that the catching portion 404 can fix the filter net 1.

In a preferable scheme, the length of the limiting block 403 is smaller than that of the fixing block 401. With this structure, the notch 2 of the filter net 1 can be put in and taken out from the gap between the limiting block 403 and the inner wall of the pipeline 3.

In a preferable scheme, the filter screen 1 comprises a holder 101, a plurality of filter rods 102 are uniformly arranged on the holder 101, and one ends of the filter rods 102 are respectively connected. From this structure, be provided with 3, filter pole 102, compare 4 filter poles 102, material saving compares 2 filter poles 102 for overall structure is stable, has effectively avoided the filter screen deformation that the impulsive force of rivers leads to, blocks the thing and runs off.

In the preferred scheme, a plurality of gaps 2 are uniformly arranged on the retainer 101, and the shapes of the gaps 2 are matched with the shapes of the limiting blocks 403. From this structure, filter screen 1 can directly put into fixed hook 4 from the one end of pipeline 3 through breach 2 on, the installation is dismantled simple and conveniently.

In a preferable scheme, the retainer 101 is circular, and the diameter of the retainer 101 is slightly smaller than that of the inner wall of the pipeline 3. With the structure, the filter screen 1 can be placed in the pipeline 3, and the operation is convenient.

In a preferable scheme, the thickness of the retainer 101 at the notch 2 is smaller than a gap between the end face of the limit block 403 and the inner wall of the pipeline 3. Due to the structure, the filter screen 1 can be easily fixed through the fixing hooks 4.

In a preferable scheme, the material of the filter screen 1 is polytetrafluoroethylene. From this structure, the effectual long-term impact and the erosive wear who has avoided rivers, simultaneously because good self-lubricating function, reduced with the 3 inner walls between the friction of pipeline, can easily take out and put into when maintaining and clearing up.

Example 2

Taking 3 pipelines with the length of 2m and the section radius of 0.1m, welding a fixed hook 4 with a section of a square with the side length of 0.01m in each 0.3m position at the left and right of the pipeline, wherein the shape of the fixed hook 4 is formed by combining cuboids of 0.01 multiplied by 0.02m, 0.01 multiplied by 0.01m and 0.01 multiplied by 0.03m, the fixed hooks 4 are positioned in the same vertical plane, and the adjacent fixed hooks 4 mutually form an angle of 120 degrees; taking a circular filter screen 1 with the radius of 0.095m, wherein three plastic-impregnated filter rods 102 with adjacent angles of 120 degrees are dispersed outwards from the center of a circle and are arranged in the circular filter screen 1, and the section of the filter screen 1 is circular with the radius of 0.01 m; the notch 2 of the filter screen 1 is positioned at 1/3 of each arc line of three same arc lines which are divided by the filter screen 1, and the notches 2 are also adjacent to each other at an angle of 120 degrees relative to the circle center. At this moment, the filter screen 1 can be installed in the pipeline, the filter screen 1 is vertically placed into the pipeline 3, the fixing hook of the pipeline 3 corresponds to the notch 2 of the filter screen 1, then the filter screen is rotated, the fixing hook 4 and the notch 2 are staggered, the filter screen 1 is fixed in the pipeline 3, and the filter screen 1 is taken out only by rotating the filter screen 1 until the fixing hook 4 corresponds to the notch 2, and then the filter screen can be taken out vertically. The design can be used for mounting and dismounting the filter screen 1 at any time and cleaning intercepted objects; the adjacent three poles that each other become 120 of filter screen 1 internal design can intercept bulky discarded object and retrieve the locator etc. and interception efficiency obtains guaranteeing, can not lead to the pipeline to block up in filter screen department because of intercepting more middle-size and small-size discarded object, also can retrieve simultaneously positioner such as GPS, the effectual waste of avoiding the material, and have stability, can not lead to the inside shape deformation of filter screen to destroy because of the impulsive force of rivers, the pressure of intercepting thing to lose filtering capability. The inside shape of filter screen is adjacent three filter rods 102 that each other become 120 jiaos, compares four or the more material saving of arc design, compares two and has more stability, and its nodical is in the filter screen centre of a circle, and the effectual impulsive force of having avoided rivers leads to the filter screen to warp, blocks the thing and runs off, pipeline 3 that has fixed hook 4 and filter screen 1 that has breach 2 can enlarge in proportion and reduce, and the size is easily adjusted, is applicable to the pipeline of each environment.

The working principle is as follows: 3 fixed hooks 4 are welded and installed in the pipeline 3 along the circumferential direction of the inner wall, the 3 fixed hooks 4 form an angle of 120 degrees with each other, when the filter screen 1 is placed, the gap 2 corresponding to the gap between the fixed hook 4 and the inner wall of the pipeline 3 is vertically placed until the fixed hook 4 is contacted with a fixed block 401, then the filter screen 1 is rotated, the positions corresponding to the gap 2 and the fixed hook 4 are staggered, at the moment, the filter screen 1 cannot be taken out of the fixed hook 4, namely, the filter screen 1 is stably placed in the pipeline 3 and works; when taking out filter screen 1, the breach 2 of rotary filter screen 1 to fixed hook 4 department, with the clearance of breach 2 corresponding fixed hook 4 and 3 inner walls of pipeline, lift filter screen 1 perpendicularly, accomplish taking out of filter screen 1, can clear up and maintain filter screen 1.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. Namely, equivalent alterations and modifications within the scope of the invention are also within the scope of the invention.
