Description

Technical Field

[0001] The invention belongs to the technical field of water supply pressurizing equipment, and in particular relates to an underground flood-proof digital water supply pressurizing equipment. Background Art

[0002] With the rapid development of urbanization, there are more and more high-rise buildings. The internal water supply of high-rise buildings generally requires secondary pressurization to supply water directly or secondary pressurization to the water tank on the roof before supplying water to the high-rise buildings. Moreover, some water plants are built far away from the urban area. The pipeline directly from the water plant to the water use site is too long, the pipeline loss is large, and the investment is high for the water plant. Therefore, a booster pump station is generally added in the middle to ensure that the water pressure of the municipal pipeline network has a certain pressure before entering the household. At present, the most common booster pump station is the traditional water supply complete set plus pump room, which uses a dry air-cooled motor inside. This installation method sometimes generates noise. If a flood disaster occurs, the pump room may be flooded, causing damage to the internal equipment, which has a great impact on residents' lives. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an underground flood-proof digital water supply pressurizing device, which is buried underground to reduce noise pollution and further avoid damage to the internal pressurizing equipment caused by flood disasters.

[0013] Beneficial Effects

[0014] The present invention can bury the booster pump station underground by setting a closed cylinder, thus saving space on the ground. Moreover, such a setting can achieve warmth in winter and coolness in summer, thereby improving the stability of the pump station operation. The use of a submersible pump as a power source not only solves the noise problem, but also has a better cooling effect on the motor, greatly extending the service life of the motor. The control unit is reduced in size and hidden in the water outlet parallel pipeline, and the flow of water can be used to cool the control unit and quickly take away the heat, thereby ensuring that the control unit is always operating in a low temperature state. By installing the air release valve inside the cylinder, the installation of the leaking parts of the booster pump station is reduced, making the overall appearance of the booster pump station clean and tidy.

[0019] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0020] The present invention provides an underground flood-proof digital water supply pressurizing device, comprising a sealed cylinder 1, wherein a plurality of wells 4 are arranged in the sealed cylinder 1, wherein the wells 4 comprise a water inlet transverse pipe, a vertical pipe and a water outlet transverse pipe connected in sequence, wherein the other end of the water inlet transverse pipe is communicated with a water inlet 19 arranged on the side of the sealed cylinder 1, and the other end of the water outlet transverse pipe is communicated with a water outlet 17 arranged on the side of the sealed cylinder 1, the top of the vertical pipe extends upward to the top of the sealed cylinder 1 and is provided with a sealing cover plate 9, wherein a submersible pump 3 for pressurizing the fluid from the water inlet transverse pipe and outputting it to the water outlet transverse pipe is arranged in the vertical pipe, an air vent valve 6 is arranged in the sealed cylinder 1 and on one side of the upper part of the vertical pipe, wherein the air vent valve 6 can quickly discharge the air in the well 4 to prevent the well 4 from generating air accumulation and affecting the water outlet flow, wherein a sealed container 15 is arranged in the water inlet transverse pipe, wherein a control unit 16 for controlling the start and close of the submersible pump 3 is arranged in the sealed container 15.

[0021] like Figure 1 As shown, in a specific embodiment, the cross-section of the closed cylinder 1 is circular, which is convenient for the underground construction of the underground pressure pump station and helps to save ground space.

[0022] A check valve 21 is provided between the vertical pipe and the water outlet transverse pipe to prevent water from flowing back. An outlet cut-off valve 22 is provided between the check valve 21 and the water outlet transverse pipe, and an inlet cut-off valve 23 is provided on the water inlet transverse pipe to cut off the water flow as needed during later maintenance and overhaul.

[0023] The vertical pipe is connected to the water outlet transverse pipe through a double flange elbow 24. A support plate 25 is provided on the upper part of the double flange elbow 24. The submersible pump 3 is fixed in the vertical pipe and in the position between the flow channels of the water inlet transverse pipe and the water outlet transverse pipe through the support plate 25. Furthermore, the support plate 25 is a sealing plate, which separates the vertical pipe from the water outlet transverse pipe. When the water is discharged, the water is only pumped from the water outlet transverse pipe by the submersible pump 3, which can improve the working efficiency of the submersible pump 3. When the water is in and out, the water flow submerges the submersible pump 3, so that the heat generated by the submersible pump 3 is taken away by the water flow in time during operation. Not using other types of booster pumps can avoid equipment overheating failures due to the inability to dissipate heat when buried underground, and reduce maintenance cycles and frequencies.

[0024] The top of the sealed container 15 is arranged on the top of the sealed cylinder 1 and is provided with a sealing cover plate 2 11, and the waterproof level of the sealed container 15 should reach IP68, further preventing the waterproof ability of the present invention when it is flooded, and preventing the control unit 16 inside it from short-circuiting and failing due to water leakage or seepage. Since the sealed container 15 is arranged in the water outlet horizontal pipe, the control unit 16 can be cooled by the water flow during the water outlet, avoiding overheating failure of the equipment due to the inability to dissipate heat when buried underground, and reducing the maintenance cycle and frequency.

[0025] An external cable 15 is installed on the top of the control unit 16. The external cable 15 passes through the sealed container 15 and the sealed cylinder 1 and is connected to the external power line to power the control unit 16. In addition, the control unit 16 can also be powered by a battery and replaced during maintenance. The control unit 16 is connected to the submersible pump 3 through the cable 5, so that various parameters of the submersible pump 3 can be monitored and controlled. In a preferred embodiment, the submersible pump 3 can also be frequency-controlled according to the water inlet and outlet pressures measured by the pressure sensors arranged at the water inlet 19 and the water outlet 17 to achieve constant pressure water supply. The control unit 16 is provided with a touch screen on the surface to realize human-computer interaction and alarm functions. The top surface of the control unit 16 is provided with a handle 13 to facilitate the installation and maintenance of the control unit 16. The threading holes of the external cable 15 and the cable 5 are both provided with sealing devices to prevent water leakage from the threading holes.

[0026] When the number of the wellbore 4 is greater than or equal to two, the water inlet transverse pipes are connected via the water inlet parallel pipe 20, and the water outlet transverse pipes are connected via the water outlet parallel pipe 18. Multiple wellbores 4 are connected in parallel via the water inlet parallel pipe 20 and the water outlet parallel pipe 18 to achieve the function of multiple use and multiple backup. In this embodiment, three sets of cylinder bodies are provided to achieve the function of two use and one backup.

[0027] In addition, if Figure 1 , 2 As shown, an inspection port 18 is provided on the top of the sealed cylinder 1, a ladder 2 is provided inside the sealed cylinder 1 and below the inspection port 18, and an inspection cover 17 is provided on the upper end of the ladder 2, so that maintenance personnel can enter the sealed cylinder 1 for operation. An inspection port 2 10 is provided on the top of the sealed cylinder 1, and the inspection port 2 10 is directly opposite to the inlet shut-off valve 23 and the outlet shut-off valve 22, and an inspection cover 2 11 is provided at the inspection port 2 10. The positions of the inspection ports 1 8 and 10 are convenient for maintenance personnel to maintain and adjust the internal pipelines and valves of the sealed cylinder 1. The inspection cover 1 7 and the inspection cover 2 11 are both sealing covers, which are sealed and connected to the sealed cylinder 1 when closed to prevent water leakage. Normally, the inspection cover 1 7 and the inspection cover 2 11 are normally closed, and are opened and closed as needed during maintenance.
