Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building foundation pit construction technology, and in particular relates to a foundation pit submersible pump bracket and foundation pit submersible pump device. Background Technology
[0002] The level of groundwater has a significant impact on foundation pit excavation and subsequent municipal structure construction. Typically, construction can only proceed after the groundwater level has dropped to a certain level at the bottom of the foundation pit. Submersible pumps are essential tools for removing water from the excavated foundation pit.
[0003] Submersible pump brackets provide support for submersible pump drainage, but they only serve to support and fix the pump and cannot adjust the depth of the pump in the pit. If the pump is placed too deep, too much silt will be drained and may damage the pump. If the pump is placed too shallow, it will be difficult to effectively drain the water in the pit.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0033] like Figures 1-6 As shown, this utility model embodiment provides a submersible pump bracket for foundation pits, used to adjust the depth of a submersible pump 5 in a foundation pit. It includes a bracket 1, placed at the bottom of the foundation pit; a rotating assembly 2, rotatably connected to the bracket 1, the axis of the rotating assembly 2 being parallel to the plane of the bottom of the foundation pit, the rotating assembly 2 including a first limiting part 22; a pump sleeve assembly 3, one end connected to the rotating assembly 2 and the other end connected to the submersible pump 5; and a limiting member 4, detachably connected to the bracket 1, the limiting member 4 including a second limiting part 41 that restricts the rotation of the first limiting part 22.
[0034] The submersible pump bracket and device for foundation pits provided by this utility model support a rotating component 2 by means of a bracket 1 set at the bottom of the foundation pit. The rotating component 2 is parallel to the plane of the bottom of the foundation pit. A submersible pump 5 is connected to it through a pump sleeve assembly 3 to adjust the depth of the submersible pump 5. A first limiting part 22 is provided on the rotating component 2 to cooperate with the second limiting part 41 of the limiting part 4, thereby limiting the rotation of the rotating component 2. That is, the limiting part 4 is removed from the bracket 1, and the rotating component 2 can rotate. After rotating to a suitable position, the limiting part 4 is installed on the bracket 1 to fix the rotating component 2. The submersible pump 5 drains water. By removing and installing the limiting part 4, the submersible pump 5 can be fixed at different depths for drainage. This utility model can achieve drainage of the submersible pump 5 at different positions by fixing the diving height of the submersible pump 5 by the limiting part 4, thereby improving drainage efficiency and reducing the damage to the submersible pump 5 caused by silt, gravel and other debris.
[0035] Please continue to refer to this. Figure 1 , 2As shown in Figure 4, the rotating assembly 2 further includes a rotating shaft 21, which includes a first end 211 and a second end 212, which are rotatably connected to both sides of the bracket 1. A limiting member 4 is detachably connected to the connection between the bracket 1 and the first end 211, with the first end 211 passing through the limiting member 4. A first limiting part 22 is disposed on the outer periphery of the first end 211, and the limiting member 4 is recessed inward to form a second limiting part 41 that restricts the rotation of the first limiting part 22. When the limiting member 4 is installed on the bracket 1, the second limiting part 41 is adapted to the shape of the first limiting part 22, and the first limiting part 22 and the rotating shaft 21 stop rotating. At this time, the submersible pump 5 drains water. When the limiting member 4 is removed, the rotating shaft 21 can continue to rotate. The submersible pump 5 drains water again when it rotates to a suitable position.
[0036] Specifically, the first limiting part 22 is a cuboid disposed on the outer periphery of the rotating assembly 2, and the second limiting part 41 is a square groove formed by a recess in the limiting member 4, the inner surface of the square groove engaging with the outer surface of the cuboid. The square groove and the cuboid are compatible in shape. When the limiting member 4 is installed on the bracket 1, the square groove of the limiting member 4 engages with the cuboid on the rotating shaft 21, thereby restricting the rotation of the rotating shaft 21. At this time, the submersible pump 5 stops at a certain height to drain water. That is, every time the rotating shaft 21 rotates 180°, the position of the rotating shaft 21 can be fixed by the limiting member 4. After fixing, the submersible pump 5 can achieve drainage at different depths, thereby effectively preventing the submersible pump 5 from moving to an excessively high or low position at once.
[0037] Furthermore, the rotating assembly 2 also includes a rotating handle 24, which is formed by bending the second end 212. By providing the rotating handle 24, the rotating shaft 21, the first limiting part 22, and the pump sleeve assembly 3 can be rotated synchronously relative to the limiting part 4, thereby adjusting the depth of the submersible pump 5.
[0038] In addition, the rotating assembly 2 also includes a lifting rope shaft 23, which is located on the outer periphery of the rotating shaft 21 and between the first end 211 and the second end 212. One end of the pump sleeve assembly 3 is wound around the lifting rope shaft 23. Multiple grooves are provided at intervals along the axial direction on the lifting rope shaft 23 to engage one end of the pump sleeve assembly 3, increase the friction between the two, and prevent the pump sleeve assembly 3 from falling off during lifting.
[0039] For the pump sleeve assembly 3, the pump sleeve assembly 3 includes a lifting rope 31, a telescopic sleeve 32 and a fastening rope 33; one end of the lifting rope 31 is connected to the lifting rope shaft 23 and the other end is connected to the telescopic sleeve 32. The telescopic sleeve 32 is fitted around the outer periphery of the submersible pump 5. The telescopic sleeve 32 can be adjusted to different diameters to accommodate different types of submersible pumps 5. The fastening rope 33 is fitted around the outer periphery of the telescopic sleeve 32 to restrain the telescopic sleeve 32 and tighten it around the submersible pump 5.
[0040] On the other hand, this utility model embodiment also provides a submersible pump device for foundation pits, which is placed at the bottom of the foundation pit and includes a submersible pump 5 and a foundation pit submersible pump bracket as described in any of the above. The submersible pump 5 is connected to the end of the pump sleeve assembly 3 away from the rotating assembly 2.
[0041] In some other embodiments, the support 1 includes a frame 12 and a hanger 11; the frame 12 is placed at the bottom of the pit, the hanger 11 is placed on the frame 12, and there is a gap between the hanger 11 and the plane where the bottom of the pit is located; the rotating component 2 is rotatably connected to the hanger 11.
[0042] Please continue to refer to the following: Figure 1 As shown, the frame 12 supports the hanger 11, which together form the support 1, providing constraint and support for the submersible pump 5 and the drainage pipe 6. The frame 12 is erected by scaffolding, specifically disc-lock or coupler-type scaffolding. The frame 12 is erected from the existing scaffolding on the construction site, which is easy to obtain materials and convenient to erect.
[0043] Please continue to refer to this. Figure 3 As shown, the hanger 11 has a first shelf 111 and a second shelf 112. The area of the first shelf 111 is smaller than the area of the second shelf 112. The first shelf 111 and the second shelf 112 are connected by rods distributed in a radiating pattern. The second shelf 112 is installed on the frame 12 through mounting holes on it. The first shelf 111 is supported by the second shelf 112. First through holes 1111 and second through holes 1112 are respectively opened on opposite sides of the first shelf 111. The first end 211 and the second end 212 of the rotating shaft 21 pass through the first through holes 1111 and the second through holes 1112 respectively. The first end 211 is provided with a first limiting part 22 outside the first through hole 1111. The second end 212 is bent to form a rotating handle 24 outside the second through hole 1112. The limiting member 4 is provided with a third through hole 42 communicating with 41. The third through hole 42 passes through the first end 211, so that the rotating shaft 21 is rotatably connected to the limiting member 4. The limiting member 4 is engaged with the first shelf 111 through the slots opened on both sides of its square groove, so that the limiting member 4 can be installed and the first limiting part 22 is engaged with the second limiting part 41, thereby fixing the depth of the submersible pump 5 and enabling it to drain water.
[0044] In addition, it also includes a drain pipe 6, which is connected to the output end of the submersible pump 5. The bracket 1 has a hole 1121 for supporting the drain pipe 6. The water pumped by the submersible pump 5 is discharged outward through the drain pipe 6. The drain pipe 6 is a soft water pipe. The hole 1121 is opened on the bracket 1 to support the drain pipe 6. Specifically, the hole 1121 can be opened in the second shelf 112. The second shelf 112 is 3m-5m away from the bottom of the pit so as to discharge the stored water to the outside of the pit.
[0045] The above description provides a detailed account of the embodiments of this utility model, but the content is merely a preferred embodiment and should not be construed as limiting the scope of this utility model. All equivalent variations and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
