Description

Technical Field

[0001] This utility model relates to the field of drainage equipment technology, and in particular to a universal sewage interception device suitable for rainwater grates. Background Technology

[0002] During the construction and design of municipal drainage ditches, multiple rainwater inlets are installed and covered with rainwater grates. To ensure drainage capacity, rainwater grates are usually designed with relatively large surface pores, allowing small pollutants to directly enter the drain pipes through the grate pores. Over time, this leads to blockages in the drainage ditches.

[0003] To address the aforementioned issues, invention patent application CN200810112073.4 discloses an environmentally friendly rainwater inlet filter bucket and a trap basket designed inside the rainwater grate. The basket has drainage holes of moderate diameter on its side, while the bottom of the basket is closed to store small-sized contaminants for regular cleaning. This method has two main problems: first, because the internal dimensions and shapes of different rainwater inlets vary, the trap basket must be customized, resulting in insufficient versatility; second, the structure, material, dimensions, and connection method of the support frame are not specified, leading to low standardization, and the processing and installation of the support frame increases additional workload.

[0004] Based on this, the invention patent with application number 201811516077.9 made improvements, optimizing the structural form and installation and fixing method of the intercepting basket. In addition to the above-mentioned improved methods, predecessors have designed various complex intercepting devices, but they are not suitable for old rainwater grates under various structural and construction environments, and are not conducive to the removal of pollutants and the cleaning of the intercepting device. Furthermore, they lack effective interception methods for fine pollutants such as silt and sand. Utility Model Content

[0005] This utility model provides a universal interception device for rainwater grates, aiming to solve the problems mentioned above, such as the insufficient applicability of existing rainwater grates, the difficulty in cleaning pollutants and the cleaning of the interception device, and the lack of effective interception methods for fine pollutants such as mud and sand.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A universal interception device for rainwater grates includes a rainwater grate, a detachable interception basket is detachably suspended directly below the rainwater grate, a disposable filter bag is detachably fitted inside the interception basket and the disposable filter bag covers the inner wall of the interception basket, a tray is placed at the bottom of the disposable filter bag and supports the bottom of the interception basket, and the disposable filter bag is located between the interception basket and the tray.

[0007] Preferably, the intercepting basket is a hollow inverted truncated square with an opening at the top and a number of drainage holes evenly distributed around the sides and bottom.

[0008] Preferably, the top of the intercepting basket has a ring of fixing protrusions along the opening, and the opening of the disposable filter bag is turned outward and tightly fitted onto the fixing protrusions.

[0009] More preferably, the disposable filter bag includes a mesh body with a plurality of filter holes, the opening of which is tightened by an elastic band and fitted onto a fixed protrusion.

[0010] Preferably, the opening of the intercepting basket is provided with an outwardly extending outer edge.

[0011] More preferably, each of the four corners of the outer edge is provided with a lower hanging ring, and the bottom inner side of the rain grate is provided with an upper hanging ring that corresponds to the lower hanging ring. The lower hanging ring and the corresponding upper hanging ring are connected by corresponding slings.

[0012] Furthermore, the lower hanging rings are symmetrical about the middle position of the sewage interception basket, and the upper hanging rings are symmetrical about the middle position of the rainwater grate. The middle position of the sewage interception basket and the middle position of the rainwater grate coincide in the vertical direction.

[0013] Furthermore, all of the slings are of the same length.

[0014] Preferably, the opening area of ​​the intercepting basket is not less than the area of ​​the rainwater grate.

[0015] Preferably, the area of ​​the tray is smaller than the bottom area of ​​the trap basket.

[0016] The beneficial effects of this utility model are: 1. The intercepting basket of this utility model is installed directly below the rain grate by suspension. During installation, only the fixation of the rain grate needs to be considered. As long as the rain grate can be installed, the intercepting basket can also be installed. There are no great restrictions on the size of the intercepting basket, which improves its versatility. The suspension ensures the installation of the intercepting basket and also ensures linkage. During installation and disassembly, the intercepting basket can be moved simultaneously by the rain grate, avoiding two operations, improving efficiency, facilitating cleaning, and making it easy to replace the disposable filter bag. 2. By using a tray to intercept and settle sediment and pollutants, rainwater carrying sediment and pollutants will first enter the tray, where they will settle. The clear liquid on the top will flow out first, leaving some sediment and pollutants in the tray. The overflowing clear liquid and other pollutants will then be filtered through a filter bag, improving filtration efficiency, reducing the amount of sediment entering, and ensuring drainage capacity.

[0018] The embodiments will be further described below with reference to the accompanying drawings.

[0019] like Figures 1-5 As shown in the preferred embodiment 1, a general-purpose intercepting device for rainwater grates includes a rainwater grate 1. A intercepting basket 2 is detachably suspended directly below the rainwater grate 1. A disposable filter bag 6 is detachably fitted inside the intercepting basket 2, and the disposable filter bag 6 covers the inner wall of the intercepting basket 2. A tray 9 is placed at the bottom of the disposable filter bag 6 and supports the bottom of the intercepting basket 2. The disposable filter bag 6 is located between the intercepting basket 2 and the tray 9.

[0020] The intercepting basket 2 is installed directly below the rain grate 1 by suspension. During installation, only the fixing of the rain grate 1 needs to be considered. As long as the rain grate 1 can be installed, the intercepting basket 2 can also be installed. There are no great restrictions on the size of the intercepting basket 2, as long as it can fit into the drain. The suspension ensures the installation of the intercepting basket 2 and also ensures linkage. During installation and disassembly, the rain grate 1 can drive the intercepting basket 2 to move simultaneously, avoiding two operations and improving efficiency. The tray 9 intercepts and settles sediment and pollutants. Rainwater carrying sediment and pollutants will first enter the tray 9 and settle inside. The clear liquid on the top will flow out first, leaving some sediment and pollutants in the tray 9. The overflowing clear liquid and other pollutants will then be filtered through the filter bag, improving filtration efficiency, reducing the amount of sediment entering, and ensuring drainage capacity.

[0021] The intercepting basket 2 is a hollow inverted truncated pyramid with an open top and a number of drainage holes 10 evenly distributed around its sides and bottom, ensuring its ability to drain and intercept wastewater.

[0022] The top of the intercepting basket 2 has a ring of fixing protrusions 12 along the opening, and the opening of the disposable filter bag 6 is turned outward and tightly fitted onto the fixing protrusions 12. The fixing protrusions 12 are used for the installation of the disposable filter bag 6.

[0023] The disposable filter bag 6 includes a mesh body 8 with several filter holes. The opening of the mesh body 8 is tightened by an elastic band 7 and fitted onto the fixing protrusion 12. It is convenient to replace and install. When in use, simply put the mesh body 8 into the intercepting basket 2, open the opening outward, and fit it onto the fixing protrusion 12.

[0024] The outer edge 11 extending outward is provided on the outside of the opening of the intercepting basket 2. The outer edge 11 can be used to fix the intercepting basket 2. When the drain outlet has a snap-fit ​​groove for the intercepting basket 2, the outer edge 11 can be placed on the snap-fit ​​groove. The suspension may not be effective at this time. The main purpose is to ensure that there is a connection between the intercepting basket 2 and the rain grate 1. On the other hand, the outer edge 11 is used to arrange the suspension assembly. When the drain outlet does not have a snap-fit ​​groove, the intercepting basket 2 is connected to and suspended from the rain grate 1 through the suspension assembly.

[0025] Each of the four corners of the outer edge 11 is provided with a lower hanging ring 4, and the bottom inner side of the rain grate 1 is provided with an upper hanging ring 3 corresponding to the lower hanging ring 4. The lower hanging ring 4 and the corresponding upper hanging ring 3 are connected by corresponding lifting straps 5. The depth of the connection can be ensured by changing the length of the lifting straps 5. Through the connection, the sewage interception basket 2 is connected to the rain grate 1.

[0026] The lower lifting rings 4 are symmetrical about the middle position of the sewage intercepting basket 2, and the upper lifting rings 3 are symmetrical about the middle position of the rainwater grate 1. The middle positions of the sewage intercepting basket 2 and the rainwater grate 1 coincide in the vertical direction. This ensures the stability of the lifting connection.

[0027] All the slings 5 ​​are of the same length to ensure stable stress during lifting.

[0028] The opening area of ​​the intercepting basket 2 is not less than the area of ​​the rainwater grate 1. This ensures that all rainwater and debris can fall into the intercepting basket 2.

[0029] The area of ​​the tray 9 is smaller than the bottom area of ​​the intercepting basket 2. This ensures that the tray 9 can be stably placed inside the intercepting basket 2. Heavier items that fall into the rainwater grate 1, such as mobile phones or keys, can also be easily found inside the tray.

[0030] like Figure 6 As shown, in a preferred embodiment 2, the sling 5 can be made of wear-resistant materials such as nylon or polyester. The rope is woven into a flat strip, which has a large contact area with the contact surface and even pressure distribution. After passing through the corresponding lifting ring, the ends are tied together. Furthermore, the form of buckle 13 and lock 14 can be adopted. The buckle 13 is provided on the strip rope body to adjust the length of the rope body, and the lock 14 is provided at both ends of the rope body to close the rope body.

[0031] The working principle of this utility model: The intercepting basket 2 is installed directly below the rain grate 1 by suspension. During installation, only the fixing of the rain grate 1 needs to be considered. As long as the rain grate 1 can be installed, the intercepting basket 2 can also be installed. The suspension not only ensures the installation of the intercepting basket 2, but also ensures linkage. During installation and disassembly, the rain grate 1 can drive the intercepting basket 2 to move simultaneously, avoiding two operations and improving efficiency. The tray 9 intercepts and settles sediment and pollutants. Rainwater carrying sediment and pollutants will first enter the tray 9 and settle inside. The clear liquid on the top will flow out first, leaving some sediment and pollutants in the tray 9. The overflowing clear liquid and other pollutants will then be filtered through the filter bag, improving filtration efficiency, reducing the amount of sediment entering, and ensuring drainage capacity.
