[0004] One embodiment of this application provides a sand filter grid for soil and water conservation, comprising:

[0005] A first frame, within which a first window position is formed;

[0006] A second frame, within which a second window position is formed; and

[0007] A filter element has multiple filter holes and is clamped and fixed between a first frame and a second frame. The first frame and the second frame are detachably connected, and the first window position and the second window position are used to expose the filter element.

[0008] In one embodiment, the first frame and the second frame are connected by screws, ropes or buckles.

[0009] In one embodiment, the first frame has a groove around its circumference, the second frame is embedded in the groove, and the outer wall of the second frame abuts against the groove wall.

[0010] In one embodiment, an anti-slip pad is further included, which is fixed to the side of the first frame or the second frame facing the filter element.

[0011] In one embodiment, the system further includes telescopic components, which are respectively provided at both ends of the first frame and both ends of the second frame along the height direction of the filter screen. The telescopic components are used to change the size of the filter screen in the width direction.

[0012] In one embodiment, the telescopic assembly includes a first telescopic rod and a second telescopic rod. One of the first and second telescopic rods has multiple limiting holes, and the other of the first and second telescopic rods has at least one limiting protrusion that engages with the limiting holes. On the first frame, the ends of the first and second telescopic rods that are furthest from each other are fixedly connected to the first frame. On the second frame, the ends of the first and second telescopic rods that are furthest from each other are fixedly connected to the second frame.

[0013] In one embodiment, along the height direction of the sand filter grid, any end of the sand filter grid is provided with a splicing structure, which is a hook or a splicing hole, and the splicing structure is used to realize the superposition and use of different sand filter grids.

[0014] In one embodiment, a reinforcing rib is further included, and the reinforcing rib is fixed at both the first window position and the second window position.

[0015] In one embodiment, a fixing plate is provided on the outer wall of the first frame or the outer wall of the second frame, and a locking hole is provided on the fixing plate for locking the sand filter grid to the outlet of the sedimentation tank.

Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] like Figures 1-5As shown, one embodiment of this application provides a sand-filtering grid for soil and water conservation, comprising: a first frame 10, a second frame 20, and a filter element 30. A first window position 11 is formed within the first frame 10. A second window position 21 is formed within the second frame 20. The filter element 30 has multiple filter holes 31. The filter element 30 is clamped and fixed between the first frame 10 and the second frame 20. The first frame 10 and the second frame 20 are detachably connected. The first window position 11 and the second window position 21 are used to expose the filter element 30.

[0028] The sand filter grid (hereinafter referred to as the sand filter grid) for soil and water conservation in the above-described embodiments adopts a three-layer detachable stacked structure, consisting of the first frame 10, the second frame 20, and the filter element 30 between the first frame 10 and the second frame 20. When the sand filter grid needs to be cleaned, the filter element 30 can be disassembled and cleaned individually, simplifying the cleaning method and reducing the workload. Furthermore, when cleaning the sand filter grid, a cleaned or new filter element 30 can be directly installed between the first frame 10 and the second frame 20, effectively ensuring the working efficiency of the sand filter grid. Since the filter element 30 in the sand filter grid is detachable, filter elements 30 with different pore sizes 31 can be replaced according to the actual particle size of the intercepted and filtered debris, improving the flexibility of the sand filter grid in use.

[0029] like Figures 1-2 As shown, specifically, the filter element 30 is made of filter cotton (e.g., highly permeable honeycomb porous filter cotton), with a plurality of filter holes 31 formed on the filter cotton through its own material structure. Alternatively, the filter element 30 is made of a metal filter screen, such as wire mesh, with a plurality of arrayed filter holes 31. The first frame 10 and the second frame 20 are made of high-strength and corrosion-resistant materials according to the actual working requirements; for example, both the first frame 10 and the second frame 20 are made of stainless steel.

[0030] like Figure 1 As shown, the first frame 10 has a groove 12 around its circumference, and the second frame 20 is embedded in the groove 12. The outer wall of the second frame 20 abuts against the groove wall of the groove 12, that is, the outer wall of the second frame 20 and the side wall of the groove 12 on the first frame 10 are tightly fitted to achieve a detachable connection between the first frame 10 and the second frame 20, and to clamp and fix the filter element 30 between the first frame 10 and the second frame 20.

[0031] More preferably, to facilitate the disassembly of the first frame 10 and the second frame 20 for cleaning or replacing the filter element 30, corresponding operating handles are provided on the first frame 10 and the second frame 20 so that workers can quickly disassemble the first frame 10 and the second frame 20 by applying force.

[0032] In this embodiment, to accommodate the structure of the water outlet and increase the sand filtration area, the sand grating is a rectangular sand grating. Correspondingly, the first frame 10, the second frame 20, and the filter element 30 are all rectangular. At this time, the external dimensions of the filter element 30 are consistent with the dimensions within the groove 12, or the external dimensions of the filter element 30 are slightly smaller than the dimensions within the groove 12, so as to facilitate the placement of the filter element 30 within the groove 12.

[0033] In other embodiments, the first frame 10 and the second frame 20 have the same structure. For example, both the first frame 10 and the second frame 20 are rectangular frames 2cm wide, and are connected by screws or ropes. Alternatively, the first frame 10 and the second frame 20 are provided with a snap-fit ​​structure to snap them together. Or, the first frame 10 and the second frame 20 are simply stacked, and are clamped and fixed by providing a corresponding limiting structure at the water outlet. More preferably, as... Figure 4 As shown, multiple positioning rods 13 can also be provided on the top of the first frame 10 or the second frame 20. The positioning rods 13 are inserted into the top of the filter element 30. In this way, during assembly, the positioning rods 13 can pass through the filter hole 31 on the top of the filter element 30 or a corresponding hole can be specially opened to initially fix the filter element 30 on the first frame 10, which facilitates the subsequent assembly of the second frame 20.

[0034] In other embodiments, the shape of the sand filter grid can also be square, circular, etc., and can be flexibly set according to the actual application scenario.

[0035] More preferably, in this embodiment of the application, the sand filter grid further includes an anti-slip pad 40, and the anti-slip pad 40 is fixed to the side of the first frame 10 or the second frame 20 facing the filter element 30. For example, as Figure 1 As shown, an anti-slip pad 40, such as a rubber pad, is fixed to the side of the second frame 20 facing the filter element 30. The contact area between the filter element 30 and the first frame 10 and the second frame 20 is limited, resulting in a limited clamping force. However, the filter element 30 experiences significant water flow impact during use. By providing the anti-slip pad 40, the frictional force on the filter element 30 can be increased, facilitating a firm fixation of the filter element 30 between the first frame 10 and the second frame 20.

[0036] The number and position of the anti-slip pads 40 can be designed based on the water flow impact force received by the filter element 30. For example, when the water flow impact force on the filter element 30 is large, anti-slip pads 40 can be installed around the entire circumference of the second frame 20, i.e., one anti-slip washer ring can be installed. When the water flow impact force on the filter element 30 is smaller, for example... Figure 1 and Figure 3As shown, a 0.5cm thick anti-slip pad 40 can be set at each of the four corners of the second frame 20, that is, an anti-slip strip can be set.

[0037] like Figures 2-3 As shown, the sand filter grid also includes a telescopic component 50, which extends along the height direction of the sand filter grid (e.g., along the height direction of the sand filter grid). Figure 2 In the vertical direction of the filter screen, telescopic components 50 are respectively provided at both ends of the first frame 10 and both ends of the second frame 20. The telescopic components 50 are used to change the width direction of the filter screen (e.g., vertical direction). Figure 2 The horizontal dimension (in the middle), for example, the telescopic component 50 can be extended to a length of 15cm.

[0038] Specifically, the telescopic assembly 50 includes a first telescopic rod 51 and a second telescopic rod 52. Multiple limiting holes 511 are formed on either the first telescopic rod 51 or the second telescopic rod 52, and at least one limiting protrusion 521 is provided on the other. The limiting protrusion 521 and the limiting hole 511 are in a concave-convex fit. On the first frame 10, the ends of the first telescopic rod 51 and the second telescopic rod 52 that are far apart from each other are fixedly connected to the first frame 10 (e.g., welded). On the second frame 20, the ends of the first telescopic rod 51 and the second telescopic rod 52 that are far apart from each other are fixedly connected to the second frame 20.

[0039] Both the first telescopic rod 51 and the second telescopic rod 52 are hollow structures. For example, multiple limiting holes 511 are opened on the first telescopic rod 51, and multiple limiting protrusions 521 are opened on the second telescopic rod 52. The limiting holes 511 and the limiting protrusions 521 correspond one-to-one. When using the sand filter, the width of the sand filter is adjusted according to the actual outlet width. The size adjustment principle of the telescopic component 50 is similar to the adjustment principle of the telescopic rod in a folding umbrella.

[0040] The telescopic component 50 installed in the sand filter effectively increases the range of outlet sizes that the sand filter can adapt to, thus improving the versatility of the sand filter.

[0041] like Figure 3 As shown, along the height direction of the filter screen, any end of the filter screen has a splicing structure, which can be a hook or a splicing hole. The splicing structure is used to allow multiple filter screens to be stacked. During the rainy season, if the water volume is too large, two filter screens can be stacked in the height direction to effectively intercept the water flow. When the splicing structure is a hook, multiple pairs of hooks can be set between two filter screens to connect them. When the splicing structure is a splicing hole, for example, a splicing plate 60 can be detachably (or fixedly) installed on the first frame 10 or the second frame 20. The splicing plate 60 has splicing holes, and two filter screens are connected by screws or connecting ropes 61.

[0042] In other embodiments, guide grooves and guide rods can be provided at both ends in the height direction of the filter screen, and the guide groove on one filter screen and the guide rod on another adjacent filter screen can be inserted horizontally to achieve a detachable connection between the two filter screens.

[0043] More preferably, in this embodiment of the application, the sand filter grid further includes reinforcing ribs 70, and the reinforcing ribs 70 are fixed to both the first window position 11 and the second window position 21. For example, as Figure 2 As shown, both the first window position 11 and the second window position 21 are fixed with two parallel reinforcing ribs 70, or both the first window position 11 and the second window position 21 are fixed with two intersecting reinforcing ribs 70 distributed diagonally. The reinforcing ribs 70 are, for example, 1cm wide stainless steel strips, which further enhance the structural strength of the sand filter grid.

[0044] like Figure 2 As shown, a fixing plate 80 is provided on the outer side wall of the first frame 10 or the outer side wall of the second frame 20. The fixing plate 80 has a locking hole 81, which is used to lock the sand filter screen to the outlet of the sedimentation tank. For example, a fixing plate 80 is provided on the left and right side walls of the first frame 10 respectively, and the sand filter screen is fixed to the outlet side wall by screws or pins passing through the locking hole 81.

[0045] The sand filter grid designed in the above embodiments of this application is a sand filter grid that is easy to install, easy to store, easy to clean, and easy to replace, and has a wide range of applications.

[0046] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
