The "connection" and "coupling" in this application include direct and indirect connections (couplings) unless otherwise specified.

[0028] As shown in Figures 1-7 A prefabricated sand setting device for water and soil conservation includes a sedimentation tank 10 and a filter body 20. The sedimentation tank 10 is divided into a water inlet area 10a and a water outlet area 10b on both sides of the filter body 20 fixed in the sedimentation tank 10. The filter body 20 includes a filter cage 21 and a plurality of filter blocks 22 filled in the filter cage 21, and the filter body 20 is used to filter the water flow from the water inlet area 10a to the water outlet area 10b through the plurality of filter blocks 22.

[0029] The assembly type sand setting device for water and soil conservation in the above embodiments is used, a filter body 20 is arranged in the sand setting pool 10, the filter body 20 includes a filter cage 21 and a plurality of filter blocks 22 filled in the filter cage 21, so that the plurality of filter blocks 22 in the filter cage 21 can play a role of sand setting and impurity interception, effectively improve the sand setting effect, and the water flow velocity in the sand setting pool 10 can be reduced through the filter body 20, and the water and soil conservation effect is greatly improved.

[0030] The assembly type sand setting device is generally arranged outdoors and mainly used for sand setting of the mud sand contained in the water flow in the water channel. Based on the use environment or scene of the assembly type sand setting device, the material of the sand setting pool 10 is a relatively hard, wear-resistant, corrosion-resistant and anti-aging material, for example, the material of the sand setting pool 10 is rubber. The filter cage 21 is used for bearing the plurality of filter blocks 22 and can bear the impact of the water flow, so it needs to have a certain strength. Based on this, the filter cage 21 can be processed by using a metal material, for example, the filter cage 21 is a wire cage. The filter block 22 needs to play a role of sand setting and impurity interception, and at the same time, the filter block 22 also needs to have a certain strength and can bear the impact of the water flow. Based on this, the filter block 22 is a gravel block, which has relatively low cost and high reusability. More preferably, the filter block 22 is a gravel block with a particle size of 3cm-5cm. If the particle size of the gravel block is too small, the water flow will be blocked, and if the particle size is too large, the sand setting effect will be reduced. The gravel block with a particle size of 3cm-5cm can ensure that the water flow smoothly flows to the water outlet area 10b and also ensure the sand setting effect.

[0031] As shown in Figure 1 , in order to fully utilize the space and ensure the volume of the water flow in the sand setting pool 10, the sand setting pool 10 is a rectangular body-shaped sand setting pool 10.

[0032] More preferably, a plurality of first fixing parts 11 are arranged on the side walls of the sand setting pool 10, the plurality of first fixing parts 11 divide to form a first filter area 10c, and the filter body 20 is detachably inserted into the first filter area 10c. For example, as shown in Figure 1 , a pair of first fixing parts 11 are arranged on the two side walls at the top of the sand setting pool 10 respectively, a pair of first fixing parts 11 are arranged on the two side walls at the bottom of the sand setting pool 10 respectively, and the first filter area 10c is divided by the four pairs of first fixing parts 11. The filter body 20 is a rectangular body-shaped filter body 20 which is adapted to the shape of the first filter area 10c, and the filter body 20 can be clamped and fixed by the first fixing parts 11 on both sides along the water flow direction of the first filter area 10c, so that the filter body 20 can stand in the sand setting pool 10.

[0033] When the filter body 20 is detachably inserted into the first filtration zone 10c, it facilitates the assembly of the prefabricated sedimentation device and improves construction efficiency. On the other hand, it improves dredging efficiency. For example, when dredging is required, the filter body 20 can be lifted out for cleaning without operating the sedimentation tank 10. The sediment on the gravel in the filter cage 21 can be removed by gently tapping and shaking it.

[0034] Better, such as Figures 2-3 As shown, the filter body 20 also includes a filter frame 23, within which a filter cage 21 filled with several filter blocks 22 is fitted. The shape of the filter frame 23 is adapted to the shape of the filter cage 21 filled with filter blocks 22; for example, the filter frame 23 is rectangular. The filter frame 23 further restricts the shape of the filter cage 21 within it, preventing deformation of the filter cage 21, and also enhances the structural strength of the entire filter body 20. The filter frame 23 is, for example, a stainless steel filter frame.

[0035] To facilitate the assembly and disassembly of the filter body 20, a lifting handle 24 is provided at the end of the filter frame 23 facing the opening of the sedimentation tank 10. The lifting handle 24 is, for example, a strip-shaped lifting handle made of metal, plastic, rope, or other materials. The filter body 20 with the lifting handle 24 has a basket-like structure, and the filter body 20 can be removed from the sedimentation tank 10 by lifting.

[0036] Better, such as Figure 1 as well as Figures 3-4 As shown, an overflow trough 25 is provided at the end of the filter cage 21 facing the pool opening of the sedimentation tank 10.

[0037] To fully utilize the filtration function of the filter element 20, the height of the filter element 20 and the height of the sedimentation tank 10 (height i.e. Figure 1 The vertical dimensions can be consistent or similar, so that the filter body 20 standing in the sedimentation tank 10 is similar to a filter wall. Since the filter body 20 is filled with gravel, it also has high structural strength and is not easily deformed. An overflow trough 25 is provided at the end of the filter cage 21 facing the opening of the sedimentation tank 10. When the water flow is large or rapid, sediment buildup in the filter body 20 can significantly affect the water flow rate. The overflow trough ensures that the water continues to flow smoothly through the filter body 20 to the outlet area 10b, preventing water from overflowing to other areas and ensuring the safe use of the prefabricated sedimentation device.

[0038] like Figure 1As shown, the top of the sand trap 10 is provided with a water inlet 12 and a water outlet 13 respectively, the water inlet 12 and the water outlet 13 are arranged at the top of the sand trap 10, so that the water flowing into the sand trap 10 can fully utilize the space in the sand trap 10, increase the settling time of the water flow in the sand trap 10, and further ensure the sedimentation effect. The space of the water inlet area 10a is larger than that of the water outlet area 10b, so as to fully sediment and filter the water flowing into the sand trap 10. For example, the filter body 20 is arranged at the position of 1 / 3 of the sand trap 10 away from the water outlet, the size of the filter body 20 along the direction of water flow in the sand trap 10 is 1 / 10 of the corresponding size of the sand trap 10 (i.e. Figure 1 the size in the horizontal direction).

[0039] Preferably, the assembled sand trap device further comprises a filter grid 30 fixed in the water outlet 13. Figure 1 and Figure 4 As shown, the water flows along the direction of the arrow, and passes through the water inlet 12, the water inlet area 10a, the filter body 20, the water outlet area 10b and the water outlet 13 in sequence. The water flowing into the water inlet area 10a is relatively dirty sewage, and the water flowing into the water outlet area 10b is relatively clean water, but there may be a small amount of sediment and impurities in the clean water in the water outlet area 10b. At this time, the filter grid 30 can be used for secondary sedimentation and impurity interception, so as to ensure the treatment effect of the assembled sand trap device on the water flow.

[0040] As shown in Figure 1 and Figure 4 The side walls of the water outlet 13 are provided with a plurality of second fixing parts 14, which divide to form a second filter area 10d, and the filter grid 30 is detachably inserted into the second filter area 10d. For example, a pair of second fixing parts 14 is fixed on the side walls on both sides of the top of the water outlet 13, and a pair of second fixing parts 14 is fixed on the side walls on both sides of the bottom of the water outlet 13, and four pairs of second fixing parts 14 divide to form the second filter area 10d, so as to facilitate the clamping and supporting of the filter grid 30. The filter grid 30 is detachably inserted into the second filter area 10d, which is convenient for regular cleaning of the filter grid 30 and also convenient for ensuring the use effect of the filter grid 30.

[0041] Among them, the plurality of first fixing parts 11 in the sand trap 10 and the plurality of second fixing parts 14 at the water outlet 13 are, for example, rubber blocks with the same material as the sand trap 10, and the first fixing parts 11 and the second fixing parts 14 are directly integrated with the sand trap 10, which is convenient for assembling and using the assembled sand trap device.

[0042] As shown in Figures 5-7As shown, the filter grid 30 comprises a detachable first frame 31, a filter piece 33 and a second frame 32 which are stacked in sequence, and the filter grid 30 is clamped between adjacent second fixed parts 14 along the water flow direction. The filter piece 33 is, for example, a layer of filter cotton or filter screen, and when the filter piece 33 is filter cotton, small particle suspended matters in the yellow mud water can be effectively intercepted and filtered. The filter grid 30 adopts a three-layer detachable structure design, and through the first frame 31 and the second frame 32, the intermediate filter piece 33 can be fixed conveniently. The three-layer stacked structure combination is convenient for disassembly, for example, when the filter grid 30 is used, the three-layer structure is assembled in sequence and inserted into the second filter area 10d, and the second fixed parts 14 of the second filter area 10d can maintain the stacking effect of the three-layer structure of the filter grid 30, and when the filter piece 33 needs to be cleaned or replaced, the filter piece 33 can be easily disassembled by taking out the filter grid 30 from the second filter area 10d.

[0043] Preferably, the first frame 31 and the second frame 32 are respectively provided with reinforcing ribs 34, and the first frame 31 and the second frame 32 are, for example, rectangular stainless steel frames, and the reinforcing ribs 34 are, for example, stainless steel strips welded on the stainless steel frames. The reinforcing ribs 34 can further enhance the structural strength of the first frame 31 and the second frame 32 and protect the filter piece 33. Specifically, taking the first frame 31 as an example, for example, as shown in Figure 5 , the reinforcing ribs 34 are respectively welded and fixed on two diagonal lines of the rectangular first frame 31, or, for example, as shown in Figure 6 , two parallel reinforcing ribs 34 are welded on the rectangular first frame 31.

[0044] Preferably, in order to facilitate the assembly of the filter grid 30, a plurality of positioning columns 35 are fixed on the top of the first frame 31 or the second frame 32, and the positioning columns 35 can be sleeved with the top of the filter piece 33, so as to preliminarily fix the position of the filter piece 33 when the filter grid 30 is assembled. For example, as shown in Figure 7 , two positioning columns 35 are arranged side by side or in parallel on the top of the first frame 31 to preliminarily fix the filter piece 33.

[0045] The existing sand settling tank is generally a brick structure or a soil structure, which is built by workers. For example, it takes 7 days to build a 3m 2 long sand settling tank, and the processing cost is nearly 10,000 yuan. It also takes about 1 hour to dredge the sand settling tank. The sand settling tank mainly utilizes the self-gravity of the sand to settle, and the sand settles relatively slowly, which takes more than 15 minutes, and when the water flow is turbulent, it may not have enough time to settle, which affects the sand deposition effect. Moreover, once the sand settling tank is built, it can only be fixed in a certain place and cannot be moved, not to mention recycled.

[0046] Correspondingly, in order to facilitate comparison, the volume of the sand trap 10 designed in the present application is also 3m 2 .

[0047] The assembled sand setting device in the above embodiment designed in the present application is mainly composed of three parts of the sand trap 10, the filter body 20 and the filter grid 30, and the three parts are also designed in a detachable and assembled structure. In this way, on the one hand, each part structure can be pre-processed for storage, and on the other hand, it can be directly assembled for later use, for example, the installation and application of the assembled sand setting device of the present application can be realized within twenty minutes, which obviously shortens the construction time, improves the construction efficiency and reduces the labor cost. The price of the whole assembled sand setting device is about 500 yuan, which also obviously reduces the material cost. When dredging, the filter body 20 and the filter grid 30 are detached, and the cleaning work can be completed within a few minutes, for example, within two minutes. The filter body 20 is in the sand trap 10, which is similar to a whole sand setting wall, that is, the whole filter body 20 can settle the sediment in the water flow, the sediment settling area is larger, the sediment settling time is shorter, and the sediment settling effect is better. Specifically, when the assembled sand setting device is actually used, the sediment settling time can reach one second, and 80% of the sediment can be deposited. Based on the structure of the assembled sand setting device, it can also be moved to other places for secondary use, even multiple reuse.

[0048] The above application uses specific examples to illustrate the present application, which is only used to help understand the present application and does not limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
