Description

Technical Field

[0001] The invention relates to the field of drainage systems, in particular to a self-precipitation filtering capillary floor drain. Background Art

[0002] Currently, floor drains are required in indoor bathrooms, balconies, and other areas to serve as the interface between the indoor floor and the drainage pipe. Existing floor drains are usually designed with an inner and outer ring, with the inner ring being a conventional drain outlet and the outer ring using a simple filtration method to filter out particulate matter and impurities.

[0003] With the increasing demand for water conservation and recycling, there's a growing need for outdoor floor drains to collect rainwater and other wastewater. However, existing floor drains, often used for wastewater treatment, often only provide simple filtration, often due to the presence of debris, such as gravel, planting soil, and earth above the drains. For example, in rooftop buildings, when sandy rainwater is encountered, even with the simple filtration of existing floor drains, the sand easily accumulates in the pipes, hindering drainage and ultimately blocking them.

DETAILED DESCRIPTION

[0029] In order to describe the technical solution of the above invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] The self-precipitation filtering capillary floor drain provided by the present invention is as follows: Figures 1 to 4 As shown, it includes embedded parts 100, a cover 200 and a guide plate 300, wherein:

[0031] The cover 200 covers the upper opening of the embedded component 100 , and is used to preliminarily filter water that is about to flow into the inner cavity of the embedded component 100 .

[0032] A partition 110 is provided at the lower portion of the inner cavity of the embedded component 100. The partition 110 divides the lower portion of the inner cavity into a sedimentation area 111 and a drainage area 112. Of course, since there is no partition at the upper portion, the two areas are connected at the upper portion. The sedimentation area 111 is used for physical sedimentation, while the drainage area 112 is used for free drainage, which can also ensure smooth drainage when the precipitation is excessive. A drain outlet 120 is provided at the bottom of the drainage area 112. The drain outlet 120 can be connected to a drainage pipe to allow water to be discharged freely, or it can be connected to a water storage tank for storage and future use.

[0033] The guide plate 300 is placed at the upper portion of the inner cavity and forms a guide opening 301 between the guide plate 300 and the side wall of the embedded component 100. The position of the guide opening 301 corresponds to the settling area 111. In other words, the water filtered by the cover 200 is guided by the guide plate 300 and falls into the settling area 111 from the guide opening 301.

[0034] The drainage area 112 is also equipped with a gravity flip mechanism 130, which includes a support plate 131, a rod barrel 132 and a capillary drainage rod 133. The rod barrel 132 is tilted and mounted on the support plate 131, and can rotate at a preset angle on the support plate 131. The lower end of the rod barrel 132 is provided with a water trap 134; the capillary drainage rod 133 is inserted into the rod barrel 132, and the high end of the capillary drainage rod 133 passes over the partition 110 and extends to the sedimentation area 111; when the water level 001 of the sedimentation area 111 is higher than the end of the capillary drainage rod 133, the capillary drainage rod 133 uses capillary action to After absorbing the water from the sedimentation area 111 and directing the water from the low-end water level line to the high end of the capillary drainage rod 133, the water is directed to the low end on the other side and stored in the water trap 134 through gravity and the adsorption effect of the capillary drainage rod 133. As the amount of water in the water trap 134 increases, the center of gravity of the rod barrel 132 gradually moves toward the drainage area 112. When the weight of the water in the water trap 134 reaches a threshold, the rod barrel 132 rotates once. At this time, the water in the water trap 134 falls into the drainage area 112, and part of the water in the capillary drainage rod 133 is also thrown out. Due to the change in weight, the rod barrel 132 and the capillary drainage rod 133 return to their initial positions, completing the reset, and this cycle continues.

[0035] The present invention can ensure drainage efficiency while allowing as little sand and soil as possible to enter the drainage pipe or water storage tank, thereby avoiding blockage caused by siltation of sand and soil.

[0036] In some embodiments, please refer to Figure 5, the cover body 200 includes an upper cover body 210, a filter membrane 220 and a lower cover body 230 from top to bottom. The upper cover body 210, the filter membrane 220 and the lower cover body 230 are fixed into a whole by bolts or buckles, and the cover body 200 can perform the first treatment on the water flow. In some embodiments, the filter membrane 220 can be removed and replaced regularly according to the usage so as not to affect the filtering effect or drainage efficiency. In some embodiments, the upper cover body 210 and the lower cover body 230 can be made of stainless steel, wherein the holes of the upper cover body 210 are relatively fine, which is used to block debris such as leaves and gravel, and protect the filter membrane 220; the filter membrane 220 can allow the water flow to pass slowly, while isolating the medium-grained sand and soil in the water flow; the holes of the lower cover plate 230 are relatively large, which is used to provide support for the filter membrane 220. Of course, the small particles of sand that pass through the filter membrane 220 will still be deposited at the bottom of the sedimentation area 111. The capillary drainage rod 133 only absorbs the water at the top of the sedimentation area 111, achieving a second treatment of the water flow. After two treatments, the sand can be prevented from entering the pipeline, solving the problem of sand blocking the drainage pipeline.

[0037] In some embodiments, please refer to Figures 2 to 4 The upper opening of the embedded part 100 is provided with a groove 140 that matches the cover 200. The cover 200 can be directly placed in the groove 140 so that the upper surface of the cover 200 is consistent with the ground height.

[0038] In some embodiments, please refer to Figures 2 to 4 , at least three support blocks 150 for placing the guide plate 300 are installed on the upper part of the inner cavity of the embedded part 100, wherein the height of one of the support blocks 150 is higher than the height of the other two support blocks 150, and the guide port 301 is located at the low point of the guide plate 300. In some embodiments, the height of the guide plate 300 on both sides is higher than the height in the middle along the direction of water flow. In other words, the plane determined by the support block 150 is an inclined plane. After the guide plate 300 is placed on the support block 150, it tilts to one side at a certain angle, and the water flows toward the middle, so that the unorganized drainage that flows into the inner cavity through the cover body 200 passes through the simple concentration of the guide plate 300 and then flows into the sedimentation area 111. In some embodiments, the guide plate 300 can be made of durable materials such as stainless steel or resin to extend its service life.

[0039] In some embodiments, please refer to Figures 2 to 4The support plate 131 is provided with a clearance groove 135, into which the rod barrel 132 is inserted. Of course, the clearance groove 135 does not affect the rotation of the rod barrel 132. A support 136 is provided on both sides of the clearance groove 135, and a rotating shaft 137 is provided on both sides of the rod barrel 132 to match the support 136. The rod barrel 132 can rotate relative to the support 136 around the rotating shaft 137. In other words, the rotating shaft 137 can serve as a fulcrum. When the weight at both ends of the rod barrel 132 changes, the rod barrel 132 can rotate around the rotating shaft 137. In addition, the rotating shaft 137 has a certain amount of movable margin relative to the support 136. When the rod barrel 132 rotates, it can also move freely back and forth in the clearance groove 135. If the water discharge is too large, this design can ensure that the rod barrel 132 will not be washed away by the water flow.

[0040] In some embodiments, please refer to Figures 2 to 4 The rod-mounting barrel 132 is provided with three sets of rotating shafts 137 along the axial direction. In actual application, considering that the capillary drainage rods 133 to be replaced may have different material designs or different batch processes, the three sets of rotating shafts 137 can be used to find the most suitable center of gravity position for installation according to the different capillary drainage rods 133 after installation.

[0041] In some embodiments, please refer to Figures 2 to 4 The rod-holding tube 132 is cylindrical, with the upper half of the cylinder cut off at the lower end and slightly retracted inward to hold the capillary drainage rod 133. The remaining lower half of the cylinder is upturned as the water trap 134, which can be used to store a small amount of water drained by the capillary drainage rod 133. This manufacturing method is simple, easy to operate, and low-cost.

[0042] In some embodiments, please refer to Figures 2 to 4 , the capillary drainage rod 133 is made of diatomaceous earth mixed with gypsum. Of course, it can also be made of other loose, porous and water-absorbent materials similar to diatomaceous earth, as long as it can achieve the functions required by this application. In some embodiments, the high end of the capillary drainage rod 133 is bent in the direction of the plumb bob. When in use, the capillary drainage rod 133 can be directly placed in the rod barrel 132 and installed. Since its material is loose, porous and water-absorbent, the top layer of water that has been precipitated can be attracted upward by capillary action. When it passes the highest point, gravity draws the water to a lower place and stores it in the water trap 134. When in idle state, that is, when the water level line 001 of the sedimentation area 111 is low, the capillary drainage rod 133 is not in contact with the water body, which also enables the capillary drainage rod 133 to be used for a long time, and when it needs to be replaced, it can be directly pulled out and replaced with a new capillary drainage rod 133.

[0043] The self-precipitation filtration capillary floor drain provided in this application has the following working process:

[0044] When rainwater or residual water from irrigation is filtered by the cover 200, it enters the inner cavity and is drained through the guide plate 300 into the sedimentation area 111 for static sedimentation. As the water level 001 slowly rises, the capillary drainage rod 133 comes into contact with the water in the sedimentation area 111, and the water is drawn upward by capillary action. After passing the highest point of the capillary drainage rod 133, it naturally falls due to gravity, passes through the entire capillary drainage rod 133, and slowly gathers in the water trap 134 at the bottom of the rod tube 132. When a certain amount of water accumulates in the water trap 134, the center of gravity of the rod tube 132 gradually moves toward the drainage area 112, gradually losing stability and causing a flip. The water in the water trap 134 falls into the drain outlet 120, and some of the water in the capillary drainage rod 133 is also thrown out, and then returns to its initial position, forming a cycle. If the water flow rate increases within a short period of time due to increased precipitation or damage to the filter membrane 220, it can be collected in the sedimentation area 111 and then overflow through the upper part of the cavity, freely entering the drainage area 112. Therefore, even large flows can be drained smoothly. Compared with conventional floor drains, the present invention has a larger drop from the sedimentation area 111 to the drainage outlet 120, so the original sediment and new large particles brought by the water flow within a short period of time are unlikely to enter the drainage area 112. Therefore, whether the water flow is small or large, the sand and soil entering the drainage outlet 120 can be reduced, solving the problem of pipe blockage.

[0045] In summary, the self-precipitation filtration capillary floor drain provided by the present invention includes an embedded part 100, a cover body 200 and a guide plate 300, wherein the cover body 200 covers the upper opening of the embedded part 100; a partition plate 110 is provided at the lower part of the inner cavity of the embedded part 100, and the partition plate 110 divides the lower part of the inner cavity into a sedimentation area 111 and a drainage area 112; a drain port 120 is provided at the bottom of the drainage area 112; the guide plate 300 is placed at the upper part of the inner cavity and forms a guide port 301 between the guide plate 300 and the side wall of the embedded part 100, and the position of the guide port 301 corresponds to the sedimentation area 111; a gravity turning mechanism 130 is also installed in the drainage area 112, and the gravity turning mechanism 130 includes a support plate 131, a rod barrel 132 and a capillary drainage rod 133, The rod barrel 132 is tilted and mounted on the support plate 131, and can be rotated on the support plate 131 by a preset angle. A water trap 134 is provided at the lower end of the rod barrel 132; the capillary drainage rod 133 is inserted into the rod barrel 132, and the high end of the capillary drainage rod 133 passes over the partition 110 and extends to the sedimentation area 111; when the water level line 001 of the sedimentation area 111 is higher than the end of the capillary drainage rod 133, the capillary drainage rod 133 uses capillary action to absorb water from the sedimentation area 111 and guide the water from the high end to the low end, and stores it in the water trap 134. As the amount of water in the water trap 134 increases, the center of gravity of the rod barrel 132 gradually moves toward the drainage area 112. When the weight of the water in the water trap 134 reaches a threshold, the rod barrel 132 rotates once and resets. The present invention can ensure drainage efficiency while allowing as little sand and soil as possible to enter the drainage pipe or water storage tank, thereby avoiding blockage caused by siltation of sand and soil.

[0046] Obviously, those skilled in the art may make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
