Description

Technical Field

[0001] The utility model relates to the technical field of drainage during traffic tunnel construction, in particular to a drainage device with a filtering function for construction of a factory traffic tunnel. Background Art

[0002] Construction drainage devices not only need to effectively remove stagnant water, but also need to be able to process and filter suspended solids and pollutants in the water. In this context, the development of drainage devices with filtering functions is particularly important. This equipment can reduce the impact on the environment, remove harmful substances and suspended matter through the filtering system, and ensure that the discharged water quality meets relevant environmental protection requirements. Designing an effective construction drainage device faces many technical challenges, including how to design an efficient filtering system, how to handle large flows of water, and how to ensure the durability and maintainability of the equipment.

[0003] After searching, the existing patent (Announcement No.: CN214143768U) discloses an energy-saving drainage device for the construction of a traffic tunnel of a pumped storage power station, including a base, a water pump installed on the base, the water pump connected to a first connecting pipe, the first connecting pipe connected to a water pumping turbine, one end of the water pumping turbine connected to a water pumping pipe, the other end of the water pumping turbine connected to a second connecting pipe, a three-way valve is provided at the other end of the second connecting pipe, a water inlet valve is provided at the connection between the lower side of the three-way valve and the second connecting pipe, an exhaust valve is provided at the right end of the three-way valve, the exhaust valve is connected to the air pumping turbine, the front end of the air pumping turbine is connected to a third connecting pipe, the other end of the third connecting pipe is connected to the air pump, the other end of the air pumping turbine is provided with an exhaust pipe, and a water outlet valve is provided at the left end of the three-way valve, and the water outlet valve is connected to the water outlet pipe. The air in the water inlet pipe can be completely extracted by the air pump, so that the water pump contacts the water source to perform water pumping work, which plays an energy-saving role.

[0004] However, in actual use, the above solution cannot filter impurities in sewage. If the drainage system cannot effectively filter impurities, it may cause blockage and wear inside the system, increasing additional maintenance and repair costs. In addition, frequent maintenance and repairs will also increase the overall operating cost of the project.

[0005] In view of this, the utility model proposes a drainage device for construction of a factory access tunnel with a filtering function. Utility Model Content

[0017] The working principle and beneficial effects of the utility model are:

[0018] 1. In the utility model, the sewage is filtered more carefully by the coarse particle filter plate and the fine particle filter plate, thereby greatly reducing the content of impurities in the water. At the same time, the coarse particle filter plate and the fine particle filter plate are tilted so that the filtered impurities can be pushed to the left by gravity and the direction of water flow and enter the first collection box and the second collection box through the first discharge port and the second discharge port for collection, thereby reducing the wear and blockage of the drainage system and equipment. Impurities such as sand, soil or other solid particles may clog the pipes or damage the pumps and valves, causing the drainage system to fail. Filtering and collecting these impurities can extend the service life of the equipment and reduce the cost of maintenance and replacement;

[0019] 2. In the utility model, the suction force in the first water inlet pipe can be increased by the second delivery pump, so that when the water flow is too large, the first delivery pump and the second delivery pump can be used to pump water at the same time, which helps to discharge sewage from the construction site in time and reduce the inconvenience and safety hazards caused by water accumulation. The simultaneous provision of the first delivery pump and the second delivery pump means that the second delivery pump can be used as a backup for the first delivery pump. This backup capacity can be started immediately when needed to ensure continuous drainage and avoid shutdowns and delays caused by failure of the first delivery pump.

[0035] Example 2

[0036] On the basis of Example 1, a preferred embodiment of a drainage device for construction of a factory traffic tunnel with a filtering function provided by the utility model is as follows: Figures 1 to 5 As shown: a first delivery pump 2 is fixedly connected to the front side of the bottom end of the first connecting pipe 3, the first delivery pump 2 and the filter box 4 are connected through the first connecting pipe 3, a first water outlet pipe 15 is fixedly connected to the front end of the first delivery pump 2, the first water outlet pipe 15 is fixed by the first delivery pump 2, so that the sewage filtered inside the filter box 4 is extracted by the first delivery pump 2 through the first connecting pipe 3 and discharged through the first water outlet pipe 15, a first control valve 16 is fixedly connected to the middle end of the first water outlet pipe 15, and the water flow rate in the first water outlet pipe 15 is controlled by the first control valve 16.

[0037] In this embodiment, a second water inlet pipe 17 is fixedly connected to the right side of the first connecting pipe 3, and the second water inlet pipe 17 is fixed by the first connecting pipe 3. A second delivery pump 18 is fixedly connected to the front end of the right side of the second water inlet pipe 17, and the first connecting pipe 3 and the second delivery pump 18 are connected by the second water inlet pipe 17. A one-way valve is provided at the middle end of the first connecting pipe 3 and the second water inlet pipe 17 to prevent sewage from flowing back in the pipeline.

[0038] In this embodiment, the front end of the second delivery pump 18 is fixedly connected to the second water outlet pipe 19 , and the second water outlet pipe 19 is fixed by the second delivery pump 18 .

During the extraction process, the sewage is transported into the water inlet hole 5 through the first water inlet pipe 14, and then enters the filter bin 6. The sewage is then first filtered through the coarse particle filter plate 7 to filter out the larger coarse particle impurities in the sewage, and then the fine particle impurities carried in the sewage are filtered out through the fine particle filter plate 8. At the same time, the coarse particle filter plate 7 and the fine particle filter plate 8 are tilted so that the filtered impurities can be pushed to the left and passed through the direction of gravity and water flow. The impurities enter the first collecting box 9 and the second collecting box 10 through the first discharge port 21 and the second discharge port 22 for collection. After the first collecting box 9 and the second collecting box 10 are full of impurities, it is only necessary to rotate the first limit buckle 12 or the second limit buckle 13 to cancel the engagement of the first collecting box 9 or the second collecting box 10, so as to draw out the first collecting box 9 or the second collecting box 10 and clean out the impurities. When the water flow is large or the first delivery pump 2 fails, it is only necessary to open the second control valve 20 and start the second delivery pump 18 to extract the sewage through the second delivery pump 18 using the second water inlet pipe 17, the first connecting pipe 3, the filter box 4 and the first water inlet pipe 14, and deliver it into the first water outlet pipe 15 through the second water outlet pipe 19.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
