[0030] The following is combined with Figure 1-Figure 4 The utility model is described in further detail.

[0031] The utility model embodiment discloses a drainage floor drain.

[0032] like Figure 1 As shown, a drainage floor drain in this embodiment includes a pipe body 100, a mounting pipe 210 with openings at both ends is provided inside the pipe body 100 and at the upper end thereof, a filtering assembly for filtering sewage entering the pipe body 100 is provided inside the mounting pipe 210 and at the upper end thereof, an opening and closing assembly for opening and closing the mounting pipe 210 is provided inside the mounting pipe 210 and at the lower end thereof, and a fixing assembly for fixing the mounting pipe 210 to the inner wall of the pipe body 100 is provided on the outer wall thereof.

[0033] In this embodiment, the side surface at the upper end of the pipe body 100 extends outward to form a mounting portion 120, through which the pipe body 100 can be preferably installed on the ground, that is, the installation of the drainage floor drain on the ground is convenient;

[0034] The installation pipe 210 is installed in the pipe body 100 by means of a fixing assembly, so that the outer wall of the installation pipe 210 is tightly fitted with the inner wall of the pipe body 100. When the lower end of the pipe body 100 installed on the ground is docked with the existing sewage pipe, so that sewage on the ground enters the pipe body 100, the filter assembly on the installation pipe 210 filters the garbage in the sewage and collects the garbage, thereby preventing the garbage from clogging the sewage pipe under the pipe body 100, thereby affecting the discharge of sewage.

[0035] When sewage enters the filter assembly, the opening and closing assembly keeps the installation pipe 210 in an open state, so that the filtered sewage can pass through the installation pipe 210 and be discharged into the sewage pipe from the lower end of the pipe body 100. When the filter assembly completes filtering the sewage, the opening and closing assembly keeps the installation pipe 210 in a closed state, so that the odor in the sewage pipe cannot overflow from the pipe body 100.

[0036] When it is actually used, garbage in sewage is filtered through the filtering component, and the opening and closing of the installation pipe 210 is controlled by the opening and closing component. Compared with the existing drainage floor drain, this embodiment can filter and discharge the sewage in the pipe body 100 to avoid clogging of the pipe body 100. At the same time, when the pipe body 100 is not in use, the installation pipe 210 is closed to prevent the odor in the sewage pipe from overflowing from the pipe body 100.

[0037] like Figure 1-2 As shown, in this embodiment, the filter assembly includes a filter cylinder 200 which is arranged in a mounting tube 210 and has an opening at one end. The opening of the filter cylinder 200 is arranged toward the upper end of the mounting tube 210. The outer wall of the filter cylinder 200 and the inner wall of the mounting tube 210 are slidingly and tightly matched. A plurality of filter holes are evenly distributed on the bottom wall of the filter cylinder 200.

[0038] In this embodiment, by setting the filter cylinder 200 and the filter holes, when the sewage passes through the filter cylinder 200, the sewage is filtered, so that the garbage in the sewage is collected on the filter cylinder 200;

[0039] In order to fully filter the sewage in the pipe body 100, the outer wall of the filter cylinder 200 and the inner wall of the mounting pipe 210 are slidably fitted with each other, which can effectively prevent leakage from the gap between the two so that the sewage is not filtered;

[0040] In actual use, a grille plate 110 is provided at the upper opening of the tube body 100, and the grille plate 110 is used to limit the filter cylinder 200 in the tube body 100. At the same time, the grille plate 110 can intercept larger garbage in the sewage to the outside of the tube body 100, avoiding blockage caused by the entry of larger garbage.

[0041] like Figure 1-4 As shown, in this embodiment, the opening and closing assembly includes a fixed circular plate 400 arranged in the mounting tube 210, and a plurality of first through grooves 401 are evenly distributed on the fixed circular plate 400. A movable movable circular plate 410 is provided in the mounting tube 210 and below the fixed circular plate 400. Second through grooves 411 staggered with the first through grooves 401 are evenly distributed on the movable circular plate 410. Relative columns 420 are provided on the movable circular plate 410, and the upper ends of the relative columns 420 are all penetrated by the fixed circular plate 400. A limiting plate 421 is provided on the upper end of the column 420. A first spring 430 is sleeved on the column 420 located between the fixed circular plate 400 and the limiting plate 421. The first spring 430 is used to drive the movable circular plate 410 to abut against the lower side surface of the fixed circular plate 400, and the upper end surface of the limiting plate 421 abuts against the lower end surface of the filter cylinder 200.

[0042] In this embodiment, by disposing the fixed circular plate 400, the first through-groove 401, the movable circular plate 410, the second through-groove 411, the column 420, the limit plate 421 and the first spring 430, the movable circular plate 410 is abutted against the fixed circular plate 400 to block the first through-groove 401 and the second through-groove 411, thereby closing the installation tube 210;

[0043] Among them, rubber pads are installed on the movable circular plate 410 and at the opening edge of the second through groove 411. Through the arrangement of the rubber pads, the second through groove 411 is better sealed when it is attached to the fixed circular plate 400, thereby preventing sewage leakage;

[0044] When the filter cylinder 200 filters sewage, the sewage squeezes the filter cylinder 200 due to the impact force of the flow and gravity, so that the filter cylinder 200 slides downward along the side wall of the installation tube 210, driving the limit plate 421 to move downward and squeeze the column 420, so that the column 420 moves downward and drives the movable circular plate 410 to move, so that the first spring 430 is in a compressed state. At this time, the movable circular plate 410 does not abut against the fixed circular plate 400, so that the installation tube 210 remains in an open state, and the filtered sewage can pass through the first through groove 401 and the second through groove 411 to flow out of the installation tube 210 and be discharged from the tube body 100;

[0045] When the filter cylinder 200 has finished filtering the sewage, the filter cylinder 200 is relieved of the force, and the first spring 430 is reset to push the limit plate 421 upward, so that the movable circular plate 410 abuts against the fixed circular plate 400 and the filter cylinder 200 is raised, so as to close the installation pipe 210, thereby preventing the odor in the sewage pipe from overflowing from the pipe body 100;

[0046] The two ends of the filter cylinder 200 are lifted and lowered by the limiting plates 421 at both ends, so that the lifting and lowering of the filter cylinder 200 is more stable and has a better effect.

[0047] In actual use, when enough garbage is collected on the filter cylinder 200 to affect the closure of the installation pipe 210, the grid plate 110 in the pipe body 100 is taken out, and then the filter cylinder 200 is taken out and cleaned before continuing to use;

[0048] like Figure 1-4 As shown, in this embodiment, a clamping groove 201 is provided on the inner side wall of the tube body 100 along its circumference, and a mounting hole 441 is provided on the side wall opposite to the mounting tube 210;

[0049] The fixing assembly includes a mounting tube 450 which is arranged on the corresponding mounting hole 441 and opens outward, a slot 501 is opened on the side wall of the mounting tube 450, a blocking plate 510 is provided at the opening of the mounting tube 450, a fixing rod 520 is provided in the mounting tube 450, one end of which extends out of the blocking plate 510 and is clamped in the clamping groove 201, the fixing rod 520 is movably arranged, a limiting circular plate 530 is provided at the other end of the fixing rod 520, a lever 540 with one end extending out of the slot 501 is provided on the fixing rod 520, and a second spring 550 for pushing one end of the fixing rod 520 to extend is provided between the limiting circular plate 530 and the mounting tube 450.

[0050] In this embodiment, through the arrangement of the card slot 201, the mounting hole 441, the mounting tube 450, the notch 501, the blocking plate 510, the fixing rod 520, the limiting circular plate 530, the lever 540 and the second spring 550, the mounting tube 450 is installed by threading the mounting tube 450 on the mounting hole 441, and one end of the fixing rod 520 is clamped in the card slot 201, thereby achieving the installation and fixation of the mounting tube 210 on the tube body 100;

[0051] The fixing rod 520 is provided with a matching inclined surface 521 at one end. When the mounting tube 210 needs to be mounted on the tube body 100, the matching inclined surface 521 on the fixing rod 520 is abutted against the inner wall of the tube body 100, and the mounting tube 210 is pressed to make the matching inclined surface 521 match the inner wall of the tube body 100, so that the fixing rod 520 approaches the mounting tube 450, so that the limiting circular plate 530 squeezes the second spring 550. When the fixing rod 520 slides to the position of the card slot 201, the second spring 550 resets and pushes the limiting circular plate 530 to move, so that one end of the fixing rod 520 is clamped into the card slot 201, thereby realizing the installation of the mounting tube 210 in the tube body 100. The installation is relatively convenient and easy to install in actual use.

[0052] When the fixing rod 520 drives the limiting circular plate 530 to move, the limiting circular plate 530 fits the inner wall of the mounting tube 450, so that the movement of the fixing rod 520 is more stable and the movement effect of the fixing rod 520 is better.

[0053] Among them, by installing the blocking plate 510, when the second spring 550 pushes the fixing rod 520 to move, the effect of extending one end of the fixing rod 520 is better;

[0054] In actual use, when the installation tube 210 needs to be removed from the tube body 100, the filter cylinder 200 is first removed, and the sliding lever 540 slides along the slot 501 to drive the fixing rod 520 to move toward the installation cylinder 450, so that one end of the fixing rod 520 is disengaged from the slot 201, and the installation of the installation tube 210 on the tube body 100 can be released.

[0055] Working principle: First, install the pipe body 100 on the ground through the installation part 120 so that the lower end of the pipe body 100 is connected to the existing sewage pipe, and the installation pipe 210 is installed on the upper end of the pipe body 100 through the fixing assembly. When sewage enters the pipe body 100, the sewage is filtered by the filtering assembly. At this time, the sewage drives the opening and closing assembly to open the installation pipe 210, so that the filtered sewage enters the pipe body 100 from the installation pipe 210 and is discharged from the lower end to the sewage pipe. When the sewage stops entering the pipe body 100, the opening and closing assembly automatically closes the installation pipe 210. When the filter cylinder 200 needs to be cleaned, remove the disassembly grid plate 110 and take out the filter cylinder 200.

[0056] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
