[0035] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] like Figure 1 As shown, the floors of bathrooms and balconies where the secondary drainage process is applied are, from bottom to top, a hardened layer, a waterproof layer 4, a mortar layer and ceramic tiles. In order to prevent the water on the ground from penetrating along the ceramic tiles and the mortar layer and accumulating on the surface of the waterproof layer 4, an interconnected drain pipe 5 and a secondary drainage water collection device are arranged through the hardened layer, so that the accumulated water on the surface of the waterproof layer 4 can be discharged into the sewer along the drain pipe 5 and the secondary drainage water collection device.
[0037] like Figure 1-4 As shown, the secondary drainage water collection device of the utility model comprises a water collection tray 1, a top cover 2 and a plurality of filter strips 3.
[0038] Among them, the water collecting tray 1 is used to collect the accumulated water on the surface of the waterproof layer 4. The top side of the water collecting tray 1 is flush with the waterproof layer 4 and is sealed and connected thereto. A leakage hole 101 is opened in the water collecting tray 1 for connecting to the drain pipe 5. After the accumulated water enters the water collecting tray 1, it flows into the drain pipe 5 through the leakage hole 101 and then is discharged into the sewer along the drain pipe 5.
[0039] The top cover 2 is used to seal the top side of the water collecting tray 1 to prevent the mortar in the mortar layer from falling into the water collecting tray 1 and blocking the leakage hole 101. The top cover 2 is located above the water collecting tray 1 and is spaced apart from it. The top cover 2 can support the mortar to facilitate construction, and the accumulated water on the surface of the waterproof layer 4 enters the leakage hole 101 through the gap between the top cover 2 and the water collecting tray 1.
[0040] The filter strips 3 are used to filter the mortar in the accumulated water. The multiple filter strips 3 are arranged at intervals along the annular path and between the top cover 2 and the water collecting tray 1, that is, the multiple filter strips 3 are enclosed to form a fence-like structure to block the mortar outside the fence. The leakage hole 101 is located in the middle of the multiple filter strips 3, and the middle refers to a certain position in the inner area of the annular structure enclosed by the multiple filter strips 3, rather than a specific center position, so that the leakage hole 101 is connected to the outside of the water collecting device through the intervals between adjacent filter strips 3, thereby preventing mortar from entering the leakage hole 101 and causing blockage, thereby ensuring the normal operation of the secondary drainage and water collecting device; one end of the filter strip 3 is fixedly set on one of the water collecting tray 1 and the top cover 2, and the other end is abutted against the other of the water collecting tray 1 and the top cover 2, that is, the water collecting tray 1 and the top cover 2 maintain a split structure, which is convenient for disassembly and assembly of the two, thereby facilitating the installation and maintenance of the secondary drainage and water collecting device.
[0041] like Figure 2 As shown, one end of the filter strip 3 is fixedly arranged on the top side of the water collecting tray 1, and the other end is abutted against the top cover 2, which can block the mortar outside the water collecting tray 1 and prevent it from entering the water collecting tray 1 and causing the loss of mortar; and in order to allow the accumulated water outside the water collecting tray 1 to flow evenly into the water collecting tray 1, it is preferred to arrange multiple filter strips 3 in a circular array around the center line of the leakage hole 101, that is, multiple filter strips 3 are arranged at intervals along a circular path.
[0042] When the amount of accumulated water on the surface of the waterproof layer 4 increases, the cross-sectional area through which the accumulated water passes between adjacent filter strips 3 also increases accordingly. The filter strips 3 are thick at the bottom and narrow at the top, that is, the interval between two adjacent filter strips 3 for the flow of accumulated water is thick at the top and thin at the bottom, so that the cross-sectional area through which the accumulated water passes between adjacent filter strips 3 increases at a faster rate, thereby facilitating the rapid discharge of the accumulated water.
[0043] like Figure 2 As shown, it is preferred that the side of the filter strip 3 close to the adjacent filter strip 3 be flat, or the side of the filter strip 3 away from the center line of the leakage hole 101 be trapezoidal, which can ensure the thick bottom and narrow top structure of the filter strip 3 and allow the accumulated water to pass evenly through the gaps between adjacent filter strips 3.
[0044] like Figure 1 and Figure 3 As shown, the top cover 2 includes a cover plate 21 and a limiting ring 22, wherein one end of the filter strip 3 away from the water collecting tray 1 is in contact with the bottom side of the cover plate 21; the limiting ring 22 is fixedly arranged on the cover plate 21, and the filter strip 3 is located inside the limiting ring 22. The limiting ring 22 is used to limit the filter strip 3, so as to prevent the filter strip 3 from detaching from the top cover 2 and to prevent the top cover 2 from sliding laterally, so as to ensure the normal operation of the secondary drainage and water collecting device.
[0045] like Figure 3As shown, one end of the filter strip 3 can also be fixed on the top cover 2, and the other end can be abutted against the water collecting tray 1; similar to the filter strip 3 on the water collecting tray 1, multiple filter strips 3 are arranged in a circular array around the center line of the top cover 2 to ensure the flow stability of the accumulated water.
[0046] When the filter strip 3 is arranged on the top side of the water collecting tray 1 for use, the blocked mortar will form a circle on the outside of the water collecting tray 1 over time, affecting the efficiency of discharging accumulated water on the surface of the waterproof layer 4. Therefore, the filter strip 3 can be made to contact with the bottom side of the water collecting tray 1 to ensure that the accumulated water enters the water collecting tray 1 in time, thereby ensuring the efficiency of discharging the accumulated water. Correspondingly, it is preferred to make the bottom side of the water collecting tray 1 flat to ensure its flatness against the filter strip 3.
[0047] like Figure 1 As shown, the two types of filter strips 3 can be lifted and used to perform secondary filtration on the mortar, so that the larger mortar is blocked on the outside of the water collecting tray 1, and the smaller mortar and accumulated water can flow into the water collecting tray 1 through the gaps between the large mortars, and then the filter strips 3 in the water collecting tray 1 can filter the smaller mortar.
[0048] like Figure 4 As shown, the water collecting pan 1 includes a pan body 11, a leveling ring 12 and a connecting pipe 13, wherein the pan body 11 is a bowl-shaped structure, and the leakage hole 101 is opened in the pan body 11, preferably in the middle position, and the outer diameter of the top cover 2 is not less than the outer diameter of the pan body 11, so that the top cover 2 can fully cover the pan body 11; the leveling ring 12 is fixedly arranged on the top side of the pan body 11, and is used to be sealed and connected with the waterproof layer 4, so as to facilitate the leveling installation of the secondary drainage water collecting device, and the filter strip 3 is abutted or fixed on the top side of the pan body 11 or the leveling ring 12; the connecting pipe 13 is fixedly arranged on the bottom side of the pan body 11, and is connected with the leakage hole 101, and is used to be connected with the drain pipe 5.
[0049] The working principle of the secondary drainage water collection device of the utility model is as follows:
[0050] like Figure 1 As shown, when the moisture on the ground penetrates along the tiles and mortar layers and accumulates on the surface of the waterproof layer 4, the accumulated water flows into the interior of the water collecting tray 1 along the gap between two adjacent filter strips 3, and is discharged into the sewer through the leakage hole 101 and the drain pipe 5, so as to prevent the accumulated water from affecting the waterproof performance of the ground; at the same time, the mortar in the mortar layer is blocked by the filter strip 3 on the outside of the water collecting tray 1, so as to prevent the mortar from entering the leakage hole 101 and causing blockage to the leakage hole 101, the drain pipe 5 and the sewer, thereby ensuring the normal operation of the secondary drainage and water collecting device.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
