[0002] A large amount of construction site sewage is generated in construction sites such as tunnel projects, civil engineering, underground projects, mines, concrete mixing plants, sand and gravel yards, and processes related to construction projects. The sewage often contains a large amount of mud, gravel, petroleum and other pollutants. If it is discharged directly into rivers or surface water, it will cause river siltation and water pollution. Moreover, the discharged water cannot be directly recycled, resulting in a waste of water resources. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a water supply and drainage device for construction engineering, which can filter waste water and recycle it, thereby avoiding pollution to the environment and wasting water resources.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A water supply and drainage device for construction engineering, comprising a wastewater tank, a water collecting tank, a funnel, a sewage pipe, a stirring motor, a stirring paddle, a sealing cover and a pull rod; the wastewater tank is provided with a water inlet pipe, the funnel is fixedly connected in the wastewater tank and is located below the water inlet pipe, the funnel is provided with a filter, and the funnel is connected to the sewage pipe; the stirring motor is fixedly connected to the wastewater tank, the stirring paddle is connected to the stirring motor, and the stirring paddle is located in the wastewater tank; the sealing cover is located above the sewage pipe, the sealing cover is slidably connected to the main shaft of the stirring paddle, the pull rod is connected to the sealing cover, the pull rod drives the sealing cover to move up and down along the main shaft of the stirring paddle, the sealing cover covers the end of the sewage pipe, the funnel is disconnected from the sewage pipe, the sealing cover leaves the end of the sewage pipe, and the funnel is connected to the sewage pipe; the water collecting tank is fixedly connected to the bottom of the wastewater tank, and an outlet pipe is provided at the bottom of the water collecting tank.

[0006] The funnel includes a funnel bracket, which is fixed to the top surface of the wastewater tank; one end of the filter is fixed to the funnel bracket and the other end is connected to the sewage pipe. The sewage pipe is L-shaped, one end is connected to the filter screen and the other end extends from the side wall of the wastewater tank.

[0007] It also includes a protective shell, the stirring motor is fixedly connected to the outside of the wastewater tank and is located on the top of the wastewater tank, and the protective shell covers the outside of the stirring motor; the protective shell is provided with a guide groove, and the pull rod is provided with a corresponding guide block, the guide block is slidably connected to the guide groove, and the guide block limits the moving stroke of the pull rod.

[0008] The sealing cover is in an inverted shape and is provided with a groove, the inner diameter of which is larger than the outer diameter of the sewage pipe; the sealing cover is sleeved on the stirring paddle main shaft, the stirring paddle main shaft is provided with a slide groove, and the sealing cover is provided with a corresponding slider, which is slidably connected to the slide groove.

[0009] The outer wall of the sealing cover is provided with an annular groove, and the bottom end of the pull rod is provided with a corresponding connecting block, which is installed in the annular groove.

[0010] The pull rod comprises a handle and a connecting rod. The handle is located outside the wastewater tank. The connecting rod is fixed to both ends of the handle. The connecting rod passes through the top surface of the wastewater tank and extends into the wastewater tank. The bottom end of the connecting rod is connected to the sealing groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The sealing cover of the present invention is slidably sleeved on the outer side of the main shaft of the stirring paddle. When the wastewater is filtered, the sealing cover can be covered on the upper port of the sewage pipe, thereby preventing water from flowing through the sewage pipe during the filtering process, thereby being able to fully separate floating objects, stones and water, ensuring that the wastewater discharged into the wastewater tank can be filtered and finally discharged through the outlet pipe, so that the discharged water flow can be recycled; after the wastewater is filtered, the sealing cover can be moved away from the port of the sewage pipe by the pulling force of the tension rod, and then the dirt squeezed inside the funnel bracket will be discharged through the sewage pipe.

[0013] 2. The sealing cover of the present invention is provided with an annular groove, and the pull rod is provided with a connecting block. The connecting block can slide inside the annular groove, and then when the main shaft of the stirring paddle drives the sealing cover to rotate, the annular groove opened in the middle of the outer wall of the sealing cover will slide on the outside of the connecting block, so that the sealing cover will not drive the connecting rod to rotate synchronously, thereby avoiding the occurrence of motion conflict. At the same time, when the connecting rod rises, the connecting rod drives the connecting block to rise, and the connecting block drives the sealing cover to rise, thereby completing the adjustment operation of the sealing cover.

DETAILED DESCRIPTION

[0021] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0022] like Figure 1-6 As shown, a water supply and drainage device for construction engineering includes a wastewater tank 1, a water collecting tank 2, a funnel 3, a sewage pipe 4, a stirring motor 5, a stirring paddle 6, a sealing cover 7, a pull rod 8 and a protective shell 9.

[0023] The wastewater tank 1 and the water collecting tank 2 are both rectangular boxes. The water collecting tank 2 is fixedly connected to the bottom of the wastewater tank 1 and is connected thereto. Four supporting legs are fixedly connected to the bottom of the water collecting tank 2. An outlet pipe 21 is fixedly connected to one side of the bottom of the water collecting tank 2. The outlet pipe 21 is used to discharge the filtered wastewater from the inside of the water collecting tank 2.

[0024] A water inlet pipe 11 is provided on the top surface of the wastewater tank 1 , which is communicated with the interior of the wastewater tank 1 . A valve is provided on the water inlet pipe 11 , which is used to introduce wastewater carrying floating objects and stones into the interior of the wastewater tank 1 .

[0025] The funnel 3 includes a funnel support 31 and a filter screen 32. The funnel support 31 is fixedly connected to the top surface of the wastewater tank 1 and is located below the water inlet pipe 11. One end of the filter screen 32 is fixedly connected to the funnel support 31, and the other end is connected to the sewage pipe 4. The sewage pipe 4 is L-shaped, one end is connected to the filter screen 32, and the other end is fixedly connected to the side wall of the wastewater tank 1 and extends from the side wall of the wastewater tank 1. The aperture of the filter screen 5 is 2 mm, and the filter screen 5 can filter out the floating objects and stones in the wastewater. The sewage pipe 4 is used to guide the floating objects and stones filtered by the filter screen 5.

[0026] The stirring motor 5 is fixedly connected to the outer top surface of the wastewater tank 1, and the stirring paddle 6 is directly connected to the stirring motor 5. The stirring motor 5 drives the stirring paddle 6 to rotate. The stirring paddle 6 is located in the wastewater tank 1. The upper blade 61 of the stirring paddle 6 is located above the sewage pipe 4. The bottom blade 61 of the stirring paddle 6 is located in the sewage pipe 4 and at its top. The blade 61 of the stirring paddle 6 can break up floating objects and stones to ensure that the sewage pipe 4 will not be blocked when discharging sewage.

[0027] The sealing cover 7 is inverted and has a groove 71. The inner diameter of the groove 71 is larger than the outer diameter of the sewage pipe 4. The sealing cover 7 is sleeved on the main shaft 62 of the stirring paddle 6. The main shaft 62 of the stirring paddle 6 is provided with a slide groove 621. The sealing cover 7 has a corresponding slider 72, and the slider 72 is slidably connected to the slide groove 621.

[0028] The pull rod 8 includes a handle 81 and a connecting rod 82. The handle 81 is located above the wastewater tank 1. The connecting rod 82 is fixedly connected to both ends of the handle 81. The connecting rod 82 passes through the top surface of the wastewater tank 1 and extends into the wastewater tank 1. An annular groove 73 is provided on the outer wall of the sealing cover 7. A corresponding connecting block 821 is provided at the bottom end of the connecting rod 82. The connecting block 821 is installed in the annular groove 73. In the process of the main shaft 62 of the stirring paddle 6 driving the sealing cover 7 to rotate, the annular groove 73 opened in the middle of the outer wall of the sealing cover 7 will slide on the outside of the connecting block 821, so that the sealing cover 7 will not drive the connecting rod 82 to rotate synchronously, thereby avoiding the occurrence of motion conflict. At the same time, in the process of the connecting rod 82 rising, the connecting rod 82 drives the connecting block 821 to rise, and the connecting block 821 drives the sealing cover 7 to rise, thereby completing the adjustment operation of the sealing cover 7.

[0029] The pull rod 8 drives the sealing cover 7 to move up and down along the main shaft 62 of the stirring paddle 6, and the sealing cover 7 covers the end of the sewage pipe 4. The funnel 3 is disconnected from the sewage pipe 4, and the sealing cover 7 leaves the end of the sewage pipe 4. The funnel 3 is connected with the sewage pipe 4, and the floating objects and stones filtered by the filter net 5 are discharged through the sewage pipe 4.

[0030] The protective shell 9 is fixedly connected to the top of the wastewater tank 1, and the protective shell 9 covers the outside of the stirring motor 5. The protective shell 9 is provided with a guide groove 91, and the connecting rod 82 is provided with a corresponding guide block 822, which is slidably connected to the guide groove 91, and the guide block 822 limits the movement of the pull rod 8, thereby preventing the connecting rod 82 from driving the sealing cover 7 to move excessively.

[0031] The working principle and working process of the present invention are:

[0032] After the construction wastewater is discharged, the wastewater first enters the wastewater tank 1 through the water inlet pipe 11. When the wastewater is filtered, the sealing cover 7 can be covered on the upper end of the sewage pipe 4, thereby preventing water from flowing through the sewage pipe 4 during the filtering process, thereby being able to fully separate floating objects, stones and water, ensuring that the wastewater discharged into the wastewater tank 1 can be filtered and finally discharged through the water outlet pipe 21.

[0033] After being filtered by the filter 32, the wastewater enters the water collecting box 2. After the water flow inside the water collecting box 2 accumulates to a certain height, it will be discharged to the outside through the outlet pipe 21. Then, the water flow discharged from the outlet pipe 21 can be recycled, thus avoiding the waste of water resources. Floating objects and stones carried in the wastewater will be filtered out by the filter 32 and remain on the filter 32.

[0034] When the floating objects and stones accumulate to a certain amount, the stirring motor 5 drives the stirring paddle 6 to rotate, and at the same time pulls the pull rod 8 upward, the pull rod 8 drives the sealing cover 7 to move upward, and the sealing cover 7 is separated from the top of the sewage pipe 4. The blades 61 of the stirring paddle 6 can break up the floating objects and stones to ensure that the sewage pipe 4 will not be blocked during sewage discharge. At this time, the floating objects and stones will enter the interior of the sewage pipe 4, and the floating objects and stones inside the sewage pipe 4 will be discharged to the outside through the sewage pipe 4.

[0035] The invention can filter waste water and recycle it, thus avoiding pollution to the environment and waste of water resources.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
