[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0015] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an underground energy-saving urban secondary water supply pump station.
[0016] Example:
[0017] Combination Figure 1 As shown, this utility model provides an underground energy-saving urban secondary water supply pump station, including a stainless steel water storage cylinder 1 and a fiberglass equipment room cylinder 2, and a secondary water supply pump station control box 21 for monitoring the stainless steel water storage cylinder 1 and the fiberglass equipment room cylinder 2. A water inlet pipe 3 is connected to the middle of the stainless steel water storage cylinder 1, and a float switch 4 is installed on the water inlet pipe 3. A 45-degree angled elbow 5 is installed at the end of the water inlet pipe 3 inside the stainless steel water storage cylinder 1, with the opening of the 45-degree angled elbow 5 facing downwards. The water flow injected through the 45-degree angled elbow 5 impacts the bottom of the stainless steel water storage cylinder 1, thereby disturbing the water and improving the ultraviolet disinfection effect. A submersible ultraviolet sterilizer is installed on the inner wall of the stainless steel water storage cylinder 1 on the side away from the water inlet pipe 3. 6. A sealed inspection well 7 is installed in the middle of the top of the stainless steel water storage cylinder 1. An air inlet pipe 8 and an exhaust pipe 9 are installed on both sides of the top of the stainless steel water storage cylinder 1, respectively. An activated carbon filter box 11 is installed on the air inlet pipe 8, and an insect screen 10 is installed on the activated carbon filter box 11. An axial flow exhaust fan 12 is installed on the exhaust pipe 9. The bottom ends of the air inlet pipe 8 and the exhaust pipe 9 both penetrate into the interior of the stainless steel water storage cylinder 1. The insect screen 10 and the activated carbon filter box 11 can filter the air entering the stainless steel water storage cylinder 1 to prevent external air from polluting the water source inside the stainless steel water storage cylinder 1. At the same time, the axial flow exhaust fan 12 installed on the exhaust pipe 9 can draw the air inside the stainless steel water storage cylinder 1 and discharge it to the outside for ventilation.
[0018] A connecting pipe 13 connects the stainless steel water storage tank 1 to the fiberglass equipment room tank 2. A variable frequency water pump 14, connected to the connecting pipe 13, is installed inside the fiberglass equipment room tank 2. A first gate valve 16 and a filter 17 are installed between the variable frequency water pump 14 and the connecting pipe 13. An outlet pipe 15 is connected to the other end of the variable frequency water pump 14. A check valve 18 and a second gate valve 19 are installed between the variable frequency water pump 14 and the outlet pipe 15. The outlet pipe 15 is evenly equipped with… Equipped with a pressure stabilizing tank 20, a pressure transmitter 22, and an electromagnetic flow meter 23, the pressure stabilizing tank 20 can prevent water hammer and assist the variable frequency water supply pump 14 in pressure regulation, thus improving the safety of the device. The stainless steel water storage tank 1 is equipped with a level gauge 24. Both the level gauge 24 and the electromagnetic flow meter 23 are electrically connected to the secondary water supply pump station control box 21. The bottom of the fiberglass equipment room tank 2 is equipped with a drainage pump 25, and a sewage pipe 26 is connected to the drainage pump 25.
[0019] Specifically, the float switch 4 is used to control the water inlet pipe 3. When the water level drops, the position of the float switch 4 drops accordingly, and water begins to enter the water inlet pipe 3, ensuring sufficient water supply inside the stainless steel water storage tank 1. At the same time, the level gauge 24 monitors the water level changes inside the stainless steel water storage tank 1 and feeds the data back to the secondary water supply pump station control box 21, which facilitates recording by management personnel and improves the practicality of the device.
[0020] The working principle and usage process of this utility model are as follows: First, water is drawn into the stainless steel water storage cylinder 1 through the water inlet pipe 3. At this time, the submersible ultraviolet sterilizer 6 is started to sterilize the water. After sterilization, the water is drawn into the fiberglass equipment room cylinder 2 through the connecting pipe 13. At this time, the variable frequency water supply pump 14 is used to pressurize the water and pump it into the water outlet pipe 15 for use by the user.
[0021] Meanwhile, the electromagnetic flowmeter 23 and the level gauge 24 are used to monitor the water level inside the fiberglass equipment room cylinder 2 and the stainless steel water storage cylinder 1, respectively, and the data is fed back to the secondary water supply pump station control box 21, so that the management personnel can record the water level.
[0022] In addition, a drainage pump 25 is installed in the recessed area of the fiberglass equipment room cylinder 2, so that the settled sewage can be pumped out through the sewage pipe 26 to ensure water safety.
[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
