Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage systems, and in particular to a pressurized drainage system. Background Technology
[0002] In drainage systems, there are situations where long-distance drainage is required. Conventional drainage methods only use a single pipe and a pump to power the drainage. However, long-distance drainage often results in low drainage efficiency due to low water pressure. Existing drainage methods are difficult to improve drainage efficiency according to actual drainage needs. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a pressurized drainage system that can improve the efficiency of long-distance drainage and meet actual drainage needs.
[0004] The technical solution of this utility model is as follows:
[0005] A pressurized drainage system includes a self-priming pump, a first pipeline pump, an inlet pipe, a delivery pipe, and a drainage pipe assembly. The inlet pipe is located at the input end of the self-priming pump, and the delivery pipe is located at the output end of the self-priming pump. The drainage pipe assembly includes a first drainage pipe and a second drainage pipe, both of which are connected to the delivery pipe. A first valve is provided on the first drainage pipe, and a second valve is provided on the second drainage pipe. The first pipeline pump is located on the second drainage pipe.
[0006] In a further technical solution, a third drain pipe is also included. The end of the conveying pipe is provided with a four-way connector, the three ends of which are respectively connected to the first drain pipe, the second drain pipe and the third drain pipe. A third valve is provided on the third drain pipe, and a second pipeline pump is provided on the third drain pipe. The ends of the second drain pipe and the third drain pipe are connected to a fourth drain pipe through a three-way connector.
[0007] In a further technical solution, the second valve and the first pipeline pump are sequentially arranged on the second drain pipe along the drainage direction. A first branch pipe is provided at the output end of the first pipeline pump on the second drain pipe, and a first drain valve is provided on the first branch pipe. The third valve and the second pipeline pump are sequentially arranged on the third drain pipe along the drainage direction. A second branch pipe is provided at the output end of the second pipeline pump on the third drain pipe, and a second drain valve is provided on the second branch pipe.
[0008] In a further technical solution, the ends of the first branch pipe and the second branch pipe are provided with water collection tanks.
[0009] In a further technical solution, a flow meter is provided on the delivery pipe.
[0010] The beneficial effects of this utility model are:
[0011] 1. The self-priming pump is turned on during drainage to provide power for drainage. When draining over a long distance, if the water flow is small, the first valve on the first drainage pipe can be opened and the second valve on the second drainage pipe can be closed for drainage in the normal way. If the water flow is large, the second valve on the second drainage pipe can be opened and the first valve on the first drainage pipe can be closed, and the first pipeline pump can be turned on to further pressurize the water flow, which can improve the efficiency of long-distance drainage. By setting two drainage pipes, the drainage efficiency can be improved according to the actual drainage needs.
[0012] 2. A third drainage pipe is installed, and the third drainage pipe and the second drainage pipe are connected in parallel. The first and second pipeline pumps on the second and third drainage pipes can be switched on and off separately. When the first or second pipeline pump needs to be shut down for maintenance, the pipeline pump that needs maintenance can be shut down, while the other one continues to drain water normally, ensuring drainage efficiency.
[0013] 3. The first branch pipe facilitates the discharge of water from the second drain pipe and the first pipeline pump during maintenance of the first pipeline pump, and the second branch pipe facilitates the discharge of water from the third drain pipe and the second pipeline pump during maintenance of the second pipeline pump.

[0017] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0018] Example:
[0019] like Figure 1As shown, a pressurized drainage system includes a self-priming pump 1, a first pipeline pump 2, an inlet pipe 3, a delivery pipe 4, and a drainage pipe assembly. The inlet pipe 3 is located at the input end of the self-priming pump 1 and is connected to a drainage water source. The delivery pipe 4 is located at the output end of the self-priming pump 1 and is used for long-distance drainage. A flow meter 5 is installed on the delivery pipe 4 to facilitate monitoring of the drainage flow rate. The drainage pipe assembly includes a first drainage pipe 6 and a second drainage pipe 7, both of which are connected to the delivery pipe 4. A first valve 8 is installed on the first drainage pipe 6, and a second valve 9 is installed on the second drainage pipe 7. The first pipeline pump 2 is installed on the second drainage pipe 7.
[0020] The working principle of the above technical solution is as follows:
[0021] The self-priming pump 1 is activated during drainage to provide power for drainage. The flow meter 5 monitors the drainage flow in the water supply pipe. During long-distance drainage, if the water flow is small, the first valve 8 on the first drainage pipe 6 can be opened and the second valve 9 on the second drainage pipe 7 can be closed for conventional drainage. If the water flow is large, the second valve 9 on the second drainage pipe 7 can be opened and the first valve 8 on the first drainage pipe 6 can be closed. The first pipeline pump 2 can be activated to further pressurize the water flow, thereby improving the efficiency of long-distance drainage. By setting up two drainage pipes, the drainage efficiency can be improved according to the actual drainage needs.
[0022] In another embodiment, such as Figure 1 As shown, based on the above embodiment, it also includes a third drain pipe 10, and a four-way connector 11 is provided at the end of the conveying pipe 4. The four-way connector 11 connects to the first drain pipe 6, the second drain pipe 7 and the third drain pipe 10 respectively at the three ends of the conveying pipe 4. A third valve 12 is provided on the third drain pipe 10, and a second pipeline pump 13 is provided on the third drain pipe 10. A fourth drain pipe 15 is connected to the end of the second drain pipe 7 and the end of the third drain pipe 10 through a three-way connector 14.
[0023] A third drain pipe 10 is installed, and the third drain pipe 10 and the second drain pipe 7 are connected in parallel. After being connected in parallel, they are connected to the fourth drain pipe 15. The first pipeline pump 2 and the second pipeline pump 13 on the second drain pipe 7 and the third drain pipe 10 can be switched on and off respectively. When the first pipeline pump 2 or the second pipeline pump 13 needs to be shut down for maintenance, one of the pipeline pumps that needs maintenance can be shut down, while the other pump continues to operate normally to drain water, ensuring stable operation of the system and ensuring drainage efficiency.
[0024] In another embodiment, such as Figure 1As shown, the second valve 9 and the first pipeline pump 2 are sequentially arranged on the second drain pipe 7 along the drainage direction. A first branch pipe 16 is provided at the output end of the first pipeline pump 2 on the second drain pipe 7, and a first drain valve 17 is provided on the first branch pipe 16. The third valve 12 and the second pipeline pump 13 are sequentially arranged on the third drain pipe 10 along the drainage direction. A second branch pipe 18 is provided at the output end of the second pipeline pump 13 on the third drain pipe 10, and a second drain valve 19 is provided on the second branch pipe 18. The ends of the first branch pipe 16 and the second branch pipe 18 face the same point, where a water collection tank 20 is provided.
[0025] The first branch pipe 16 facilitates the discharge of water from the second drain pipe 7 and the first pipe pump 2 during maintenance of the first pipe pump 2. The second branch pipe 18 facilitates the discharge of water from the third drain pipe 10 and the second pipe pump 13 during maintenance of the second pipe pump 13. The discharged water can be collected in the water collection tank 20 for easy disposal.
[0026] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
