Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to foundation pit drainage equipment. Background Art

[0002] A foundation pit is a pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. It is mainly used to facilitate foundation construction and provide excavation space. It is a common engineering measure in civil engineering, especially when laying foundations or underground construction is carried out at construction sites. When excavating foundation pits in areas with abundant groundwater, it is particularly important to drain the interior of the foundation pit. The drainage system of the foundation pit is usually composed of drainage ditches, collection wells and drainage equipment. The drainage ditch diverts the water inside the foundation pit to the collection well, and then discharges it outward through the drainage equipment.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a foundation pit drainage device, including a support mechanism 1, a lifting mechanism 2 is fixedly connected to the lower part of the support mechanism 1, a drainage mechanism 3 is fixedly connected to the lower part of the lifting mechanism 2, and a cleaning mechanism 4 is fixedly connected to the surface of the drainage mechanism 3. The support mechanism 1 includes a longitudinal support frame 11, a slider 18 and a slide rail 17. The top of the longitudinal support frame 11 is fixedly connected to a transverse support frame 15, the upper part of the transverse support frame 15 is fixedly connected to a slider 18, the slide rail 17 is slidably connected to the slider 18, and the bottom of the slide rail 17 is fixedly connected to a second transverse support frame 16. The lifting mechanism 2 includes a No. 1 electro-hydraulic push rod 21, one end of the No. 1 electro-hydraulic push rod 21 is fixedly connected to the No. 2 transverse support frame 16, and the other end of the No. 1 electro-hydraulic push rod 21 is fixedly connected to the fixed frame 22. The drainage mechanism 3 includes a filter box 31 and a drain pipe 33. The filter box 31 is fixedly connected to the fixed frame 22, and a water pump 32 is fixedly connected to the inside of the filter box 31. The water pump 32 is fixedly connected to the drain pipe 33. Both ends of the longitudinal support frame 11 are threadedly connected to threaded support rods 13, and the bottom of the threaded support rods 13 is fixedly connected to a support plate 14. The bottom of the longitudinal support frame 11 is fixedly connected to the wheel 12. A through groove is provided on the side of the No. 1 slide rail 17, and a locking bolt 19 is provided inside the through groove. The locking bolt 19 is threadedly connected to the No. 1 slider 18, and the locking bolt 19 is tightly squeezed and fixed to the side wall of the No. 1 slide rail 17. The upper part of the fixed frame 22 is fixedly connected to the limiting outer tube 23, and the limiting inner tube 24 is inserted into the inner part of the limiting outer tube 23. The limiting inner tube 24 is fixedly connected to the bottom of the No. 2 transverse support frame 16.

[0023] The following is a detailed description of the specific settings and functions of this embodiment. According to the width of the sump, the No. 1 slider 18 slides along the No. 1 slide rail 17 to adjust the distance between the two longitudinal support frames 11 to avoid the distance between the two longitudinal support frames 11 being too large, resulting in the overall occupation of the foundation pit area being too large. After the position of the longitudinal support frame 11 is adjusted appropriately, the locking bolt 19 is tightened to lock and fix the No. 1 slider 18 and the No. 1 slide rail 17, and then the whole is pushed to move. The rolling of the wheel 12 facilitates the movement of the whole. After the drainage mechanism 3 is moved to the upper part of the sump, the screw is turned. The threaded support rod 13 supports the support plate 14 against the ground, so that the wheel 12 is separated from the ground, which is convenient for the overall installation on the upper part of the water collection well. Then, the No. 1 electro-hydraulic push rod 21 is extended to push the drainage mechanism 3 downward. After the drainage mechanism 3 is placed inside the water collection well, the pipe for external drainage is connected to the drainage pipe 33, and the water in the foundation pit is discharged to the outside through the water pump 32. The water is filtered through the filter box 31. In the process of the fixed frame 22 moving up and down, the limiting outer tube 23 slides along the limiting inner tube 24, thereby limiting the movement of the fixed frame 22 and improving its movement stability.

[0024] Example 2: Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the cleaning mechanism 4 includes a fixed plate 41, which is fixedly connected to the side of the filter box 31. A second electro-hydraulic push rod 42 is fixedly connected to the lower portion of the fixed plate 41. A connecting rod 43 is fixedly connected to the lower portion of the second electro-hydraulic push rod 42. Both ends of the connecting rod 43 are fixedly connected to scrapers 44, and the scrapers 44 are in contact with the surface of the filter box 31. A second slide rail 45 is fixedly connected to the side of the filter box 31. A second slider 46 is slidably connected inside the second slide rail 45. The second slider 46 is fixedly connected to the side of the connecting rod 43.

[0025] The effect achieved by the entire embodiment is that, during the drainage process, the connecting rod 43 and the scraper 44 are driven to move by telescoping the No. 2 electro-hydraulic push rod 42, and the impurities attached to the surface of the filter box 31 are cleaned by the scraper 44 to avoid the filter holes on the surface of the filter box 31 from being blocked. During the up and down movement of the connecting rod 43, the No. 2 slider 46 slides along the No. 2 slide rail 45 to limit the movement of the connecting rod 43 and improve the stability of the movement of the connecting rod 43.

[0026] The method of use and working principle of this device are as follows: According to the width of the sump, the distance between the two longitudinal support frames 11 is adjusted by sliding the No. 1 slider 18 along the No. 1 slide rail 17. After the position of the longitudinal support frame 11 is adjusted appropriately, the locking bolt 19 is tightened to lock and fix the No. 1 slider 18 and the No. 1 slide rail 17. Then, the whole is pushed to move. The movement of the whole is facilitated by the rolling of the wheels 12. After the drainage mechanism 3 is moved to the upper part of the sump, the threaded support rod 13 is screwed to support the support plate 14 with the ground, so that the wheels 12 are off the ground.

[0027] Then, the No. 1 electro-hydraulic push rod 21 is extended to push the drainage mechanism 3 downward. After the drainage mechanism 3 is placed inside the water collection well, the pipe for external drainage is connected to the drainage pipe 33, and the water in the foundation pit is discharged outward through the water pump 32. The water is filtered through the filter box 31. During the drainage process, the No. 2 electro-hydraulic push rod 42 is extended and retracted to drive the connecting rod 43 and the scraper 44 to move. The scraper 44 is used to clean the impurities attached to the surface of the filter box 31 to avoid the filter holes on the surface of the filter box 31 from being blocked. During the up and down movement of the connecting rod 43, the No. 2 slider 46 slides along the No. 2 slide rail 45 to limit the movement of the connecting rod 43.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
