[0038] In addition, in this application, descriptions such as "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0039] The sand filling device is a device to ensure that the sand filling volume in the construction process meets the design requirements and improve the precipitation efficiency. It is divided into an upper feeding port and a lower steel casing according to the composition parts; it is divided into an adjustable type and a fixed type according to the structural form.

[0040] In the related art, after the pipes are fixedly connected, the overall volume of the pipes is relatively large, making it difficult to install the pipes into the precipitation well again.

[0041] To solve the problems in the related art to a certain extent, the embodiment of this application provides a sand filling device for a precipitation well. When the pipe needs to be installed into the precipitation well, only the pipe barrel 11 needs to be first placed into the precipitation well, and then the bottom of the feeding pipe 12 is aligned with the top of the pipe barrel 11. And through the positioning component 26, the slot 22 is aligned directly above the inserting rod 21, and the feeding pipe 12 is pushed downward so that the inserting rod 21 is inserted into the slot 22. When the movable plate 23 moves into the slot 22, it will be squeezed by the slot 22 and shrink into the inserting rod 21, and the spring 24 is in a squeezed state. When the movable plate 23 moves into the fixed cavity 25, the movable plate 23 expands due to the resilience of the spring 24, so that the bottom of the movable plate 23 catches the fixed cavity 25.

[0042] The following describes this application with reference to the accompanying drawings and specific embodiments:

[0043] Combined Figures 1 - 3 , the embodiment of this application provides a sand filling device for a precipitation well, including the device body 1; the device body 1 includes: a feeding pipe 12 is arranged at the top of the pipe barrel 11; a connecting component 2 is arranged between the pipe barrel 11 and the feeding pipe 12, and the connecting component 2 includes: an inserting rod 21 is arranged at the top of the pipe barrel 11, and a slot 22 matching the inserting rod 21 is arranged on the feeding pipe 12; movable plates 23 are symmetrically arranged on the inserting rod 21 and are rotatably connected to the inserting rod 21; springs 24 are arranged between the movable plates 23; a fixed cavity 25 is arranged inside the inserting rod 21 and is located at the top of the slot 22; a positioning component 26 is arranged outside the pipe barrel 11 and the feeding pipe 12.

[0044] During use, first place the tube barrel 11 into the dewatering well. Subsequently, align the bottom of the feed pipe 12 with the top of the tube barrel 11, and through the positioning assembly 26, align the slot 22 directly above the insertion rod 21. Then, push the feed pipe 12 downward so that the insertion rod 21 is inserted into the slot 22. When the movable plate 23 moves into the slot 22, it will be squeezed by the slot 22 and contract into the insertion rod 21, and the spring 24 is in a compressed state. When the movable plate 23 moves into the fixed cavity 25, the movable plate 23 expands due to the resilience of the spring 24, causing the bottom of the movable plate 23 to catch the fixed cavity 25, thereby fixedly connecting the tube barrel 11 and the feed pipe 12. The tube barrel 11 and the feed pipe 12 support the inner wall of the dewatering well, preventing the dewatering well from collapsing during construction. At the same time, by separately placing the tube barrel 11 and the feed pipe 12 into the dewatering well for connection, the convenience of installing the tube barrel 11 and the feed pipe 12 in the dewatering well is increased, and the fixed connection between the tube barrel 11 and the feed pipe 12 is facilitated. After installation, by manually pouring filter sand into the pipe, the sand filling is completed.

[0045] Specifically, the feed pipe 12 is composed of assembled parts.

[0046] Specifically, during disassembly, first disassemble the feed pipe 12 into four pieces and rotate the disassembled feed pipe 12. When the fixed cavity 25 inside the feed pipe 12 squeezes the movable plate 23, after the disassembled feed pipe 12 is rotated 90 degrees, the movable plate 23 will be squeezed and retracted into the insertion rod 21, making the movable plate 23 unable to catch the fixed cavity 25, and then the feed pipe 12 can be pulled out.

[0047] In some embodiments, the positioning assembly 26 includes: a positioning rod 261 is arranged on the outside of the tube barrel 11, and a positioning sleeve 262 that cooperates with the positioning rod 261 is arranged on the outside of the feed pipe 12. When aligning the positioning slot 22 and the insertion rod 21, it is only necessary to align the positioning sleeve 262 on the outside of the feed pipe 12 with the positioning rod 261. When the feed pipe 12 moves downward, the positioning sleeve 262 on the outside of the feed pipe 12 will be sleeved on the positioning rod 261.

[0048] In some embodiments, a telescopic tube 241 is arranged between the movable plates 23 and is located inside the spring 24, supporting the spring 24 and at the same time playing a role in limiting the movable plate 23.

[0049] In some embodiments, both ends of the telescopic tube 241 are provided with sliders 242, which are rotatably connected to the telescopic tube 241. The movable plate 23 is provided with a chute 243 that cooperates with the slider 242, enabling the telescopic tube 241 to be slidably connected to the movable plate 23. When the movable plate 23 is contracted into the insertion rod 21, the telescopic tube 241 slides upward through the slider. When the movable plate 23 expands after contraction, the telescopic tube 241 slides downward through the slider, preventing the telescopic tube 241 from affecting the contraction and expansion of the movable plate 23.

[0050] In some embodiments, a connecting plate 211 is provided at the bottom of the insertion rod 21, and an installation groove 212 for mating with the connecting plate 211 is provided on the tube barrel 11 and fixed by bolts. By disassembling and assembling the bolts, the disassembly and assembly of the insertion rod 21 can be completed, increasing the convenience of disassembling and assembling the insertion rod 21.

[0051] In some embodiments, a sealing gasket 27 is provided at the top of the feed pipe 12. By means of the sealing gasket 27, the gap between the tube barrel 11 and the feed pipe 12 is reduced, increasing the sealing performance after the connection between the tube barrel 11 and the feed pipe 12.

[0052] In some embodiments, the feed pipe 12 includes: a pipe wall 121 symmetrically disposed at the top of the tube barrel 11; an empty groove 122 symmetrically disposed on the outer side of the pipe wall 121; a fixing bolt 123 disposed inside the empty groove 122 and passing through the pipe wall 121. By assembling the pipe walls 121 and then passing the fixing bolt 123 through the empty groove 122 in the pipe wall 121 and tightening with a nut, the pipe walls 121 are fixedly connected. Since the feed pipe 12 is composed of four pipe walls 121 with the same radius, by selecting the pipe walls 121 with corresponding radii according to the diameter of the precipitation well, the feed pipe 12 that matches the precipitation well can be assembled, enabling the feed pipe 12 to be used for precipitation wells of different sizes.

[0053] Specifically, the pipe walls 121 have different radii.

[0054] In some embodiments, a handle 13 is provided on the outer side of the pipe wall 121, increasing the convenience of moving the feed pipe 12.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification.

[0056] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them.
