Description

Technical Field

[0001] The utility model relates to the technical field of engineering drainage, in particular to a drainage device for engineering construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. During the construction of water conservancy projects, it is necessary to drain the construction site to ensure the normal construction.

[0003] The existing technology patent (patent name: A drainage device for engineering construction, patent number: 202320473607.6) is provided with an inner cylinder and an outer cylinder. By discharging sewage from the water inlet into the outer cylinder, the water level in the outer cylinder gradually rises, and the water enters the inner cylinder and is finally discharged from the water outlet. During the process, solid waste in the sewage is deposited and filtered through the filter plate, which greatly reduces the solid waste in the water and avoids damage to the drainage pump and blockage of the drainage device.

[0004] However, the above technical patent has the following defects: (1) Floating garbage may enter the inner side of the inner cylinder as the water level rises, and then as the water level inside the inner cylinder rises, the filter plate may be blocked. The top rod only penetrates the filter holes on the filter plate and cannot remove the floating garbage inside the inner cylinder. The floating garbage can only be removed by stopping the injection of sewage and draining the water inside the inner cylinder, thereby increasing the workload of the staff and reducing the sewage treatment efficiency; (2) The staff is required to regularly salvage the floating garbage inside the outer cylinder, further increasing the workload of the staff. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art and to propose a drainage device for engineering construction.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A drainage device for engineering construction comprises an outer cylinder and a filter inner cylinder arranged inside the outer cylinder, an adapter ring is rotatably provided on the side wall of the outer cylinder, a fixing hole is provided on the side wall of the adapter ring, a sewage injection pipe is fixedly connected to the side wall of the outer cylinder, a plurality of filter holes are provided on the surface of the filter inner cylinder, a sewage discharge pipe is fixedly connected to the side wall of the filter inner cylinder, and the sewage discharge pipe is fixedly connected to the fixing hole, a garbage infiltration inlet is provided on the side wall of the outer cylinder, a garbage collection box is fixedly connected to the outer side wall of the outer cylinder at the garbage infiltration inlet, an opening is provided on the side wall of the garbage collection box, and a transfer box is provided inside the opening.

[0013] Preferably, the bottom end of the filter inner cylinder is fixedly connected to a drive shaft extending to the inside of the sewage pipe, and the surface of the drive shaft is provided with spiral conveying blades.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This solution is equipped with an outer cylinder and a filter inner cylinder. Sewage is injected into the outer cylinder through a sewage injection pipe, and then enters the filter inner cylinder through the filter holes. Under the action of the filter holes, impurities can be prevented from entering the filter inner cylinder. Finally, the filtered sewage is discharged through the sewage discharge pipe. Since the filter holes are arranged on the side wall of the filter inner cylinder, floating garbage will not enter the filter inner cylinder, thereby facilitating the cleaning of floating garbage.

[0016] 2. This solution is equipped with a push cylinder, an arc-shaped sealing plate and a garbage recycling box. When it is necessary to clean floating garbage, the push cylinder can be opened to make the arc-shaped sealing plate seal the filter hole. At this time, sewage cannot enter the inner filter cylinder, causing the water level inside the outer cylinder to continue to rise, and then the floating garbage rises with the rising water level. When the floating garbage reaches the garbage seepage outlet, the sewage and floating garbage enter the inner side of the transfer box through the garbage seepage outlet, realizing the automatic salvage and recovery function of the floating garbage.

[0017] 3. This solution is provided with a drive motor, a drive shaft and a spiral conveying blade. The drive motor drives the spiral conveying blade to rotate through the drive shaft, which can quickly discharge impurities such as mud and sand deposited inside the inner cylinder and avoid blockage of the sewage pipe.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1 - Figure 6 A drainage device for engineering construction includes an outer cylinder 1 and a filter inner cylinder 9 arranged inside the outer cylinder 1. The side wall of the outer cylinder 1 is rotatably provided with an adapter ring 2, and the side wall of the adapter ring 2 is provided with a fixing hole. The side wall of the outer cylinder 1 is fixedly connected to a sewage injection pipe 7;

[0027] It should be noted that: under the action of the adapter ring 2, the sewage discharge pipe 14 can rotate with the filter inner cylinder 9, while ensuring that the sewage discharge pipe 14 can extend to the outside of the outer cylinder 1.

[0028] A plurality of filter holes 901 are provided on the surface of the filter inner cylinder 9, a sewage discharge pipe 14 is fixedly connected to the side wall of the filter inner cylinder 9, and the sewage discharge pipe 14 is fixedly connected to the fixed hole, a garbage infiltration inlet 102 is provided on the side wall of the outer cylinder 1, and a garbage recycling box 4 is fixedly connected to the outer wall of the outer cylinder 1 at the garbage infiltration inlet 102, and an opening is provided on the side wall of the garbage recycling box 4, and a transfer box 5 is provided inside the opening.

[0029] It should be noted that: when it is necessary to clean the floating garbage, the push rod cylinder is turned on, and the cylinder 6 is pushed to drive the arc-shaped sealing plate 8 to move, so that the arc-shaped sealing plate 8 realizes the sealing function of the filter hole 901. At this time, the sewage cannot enter the filter inner cylinder 9, so that the water level inside the outer cylinder 1 continues to rise, and then the floating garbage rises with the rising water level. When the floating garbage reaches the garbage seepage outlet, the sewage and the floating garbage enter the inner side of the transfer box 5 through the garbage seepage outlet, realizing the automatic salvage and recovery function of the floating garbage.

[0030] Furthermore, a pushing cylinder 6 is installed on the outer wall of the outer tube 1 , and an output end of the pushing cylinder 6 extends to one end inside the outer tube 1 and is fixedly connected to a curved sealing plate 8 .

[0031] Furthermore, elastic cotton is provided on one side of the garbage recycling box 4, and a rubber layer is provided on the surface of the elastic cotton.

[0032] It is worth noting that the elastic cotton combined with the rubber layer can significantly enhance the sealing function of the arc-shaped sealing plate 8 on the filter hole 901.

[0033] Furthermore, a circular opening is opened on the side wall of the transfer box 5 , and a reflux pipe 11 plugged into the circular opening is fixedly connected to the side wall of the outer tube 1 , and a solenoid valve is provided on the reflux pipe 11 .

[0034] It should be noted that the sewage inside the transfer box 5 can be discharged back into the outer tube 1 by opening the solenoid valve.

[0035] It is worth noting that the diameter of the return pipe 11 is not sufficient to allow floating garbage to pass through, thereby preventing the floating garbage from flowing back into the outer tube 1 along with the sewage; a rubber layer is provided on the surface of the return pipe 11, and when the circular port is plugged into the return pipe 11, the sealing between the circular port and the return pipe 11 can be ensured to avoid water leakage.

[0036] Furthermore, a driving motor 3 is installed at the top of the outer cylinder 1, and the output end of the driving motor 3 is fixedly connected to the filter inner cylinder 9. The side wall of the outer cylinder 1 is provided with an observation window 101 for observing floating garbage. The bottom end of the outer cylinder 1 is fixedly connected to a sewage pipe, and a sealing plug 12 is provided at the pipe mouth of the sewage pipe. The bottom end of the filter inner cylinder 9 is fixedly connected to a driving shaft 13 extending to the inside of the sewage pipe, and the surface of the driving shaft 13 is provided with a spiral conveying blade 10.

[0037] It should be noted that the driving motor 3 drives the filter inner cylinder 9 to rotate, and then drives the spiral conveying blade 10 to rotate, which can quickly discharge the mud and sand deposited at the bottom of the inner cylinder and avoid clogging of the sewage pipe.

[0038] It should be noted that the provision of the observation window 101 facilitates the staff to observe the content of floating garbage inside the inner tube, so as to determine whether the floating garbage needs to be cleaned.

[0039] When the utility model is in use, sewage is injected into the outer cylinder 1 through the sewage injection pipe 7, and the sewage enters the interior of the filter inner cylinder 9 through the filter hole 901. The filter hole 901 realizes the filtering function of impurities. When the sewage water level in the filter inner cylinder 9 reaches the sewage discharge pipe 14, it will be discharged through the sewage discharge pipe 14. Since the filter hole 901 is set on the side wall of the filter inner cylinder 9, floating garbage will not enter the interior of the filter inner cylinder 9, thereby facilitating the cleaning of floating garbage.

[0040] When the staff observes through the observation window 101 that the content of floating garbage inside the inner tube exceeds the standard, they start the push cylinder 6, which drives the arc-shaped sealing plate 8 to move, realizing the sealing function of the filter hole 901. At this time, the sewage cannot enter the filter inner tube 9, causing the water level inside the outer tube 1 to continue to rise, and then the floating garbage rises with the rising water level. When the floating garbage reaches the garbage seepage outlet, the sewage and floating garbage enter the inner side of the transfer box 5 through the garbage seepage outlet, realizing the automatic salvage and recovery function of the floating garbage;

[0041] When the sewage treatment is completed, the sealing plug 12 is opened and the drive motor 3 is turned on. The drive motor 3 drives the filter inner cylinder 9 to rotate, and then drives the spiral conveying blade 10 to rotate through the drive shaft 13, so that the mud and sand deposited at the bottom of the inner cylinder can be quickly discharged, while avoiding blockage of the sewage pipe.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
