Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and particularly relates to a drainage device for a sewage pump box. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or for reuse. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people;

[0003] During the sewage treatment process, when transferring the sewage in the sewage pump box, a water pump is needed for pumping. In an ordinary sewage pump box, only one water pump is used. When the water pump breaks down, the water in the sewage pump box cannot be pumped and transferred in time. And when setting up a standby water pump, they all use the same power supply. When the power supply is cut off, the standby water pump cannot be used either. Therefore, we propose a drainage device for a sewage pump box. Utility Model Content

[0025] The various embodiments of the present application may exist in the form of a range. It should be understood that the description in the form of a range is only for convenience and brevity and should not be construed as a rigid limitation on the scope of the present application. Therefore, it should be considered that the described range description has specifically disclosed all possible sub-ranges and single values within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within that range, such as 1, 2, 3, 4, 5, and 6, regardless of the range.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, or B exists alone. Where A and B can be singular or plural. In this application, "at least one" means one or more, and "multiple" means two or more. "At least one kind", "at least one of the following items (pieces)" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can both represent: a, b, c, a - b (i.e., a and b), a - c, b - c, or a - b - c, where a, b, and c can be single or multiple respectively.

[0027] As Figures 1-3 shown, an embodiment of this application provides a drainage device for a sewage pump box, including:

[0028] A sewage pump box 1, the sewage pump box 1 is in an "L" shape, a high plate and a low plate are provided at the upper end of the sewage pump box 1, a water pump motor 2 is provided at the upper end of the low plate, a lifting impeller is inserted at the lower end of the rotating shaft of the water pump motor 2 inside the water pump housing, and a water outlet port 9 is further provided at the upper end of the water pump housing, and a first starting float 11 is also connected to the outside of the water pump housing;

[0029] A standby water pump 12, the standby water pump 12 is arranged at the lower end of the inner cavity of the sewage pump box 1, a second starting float 10 is provided on the standby water pump 12, and the standby water pump 12 is also connected to a UPS power supply 8 through a wire, and the water outlet of the standby water pump 12 is connected to a second pipeline 7;

[0030] A vibration switch 6, the vibration switch 6 is connected to the UPS power supply 8 and an audible and visual alarm 5 through a wire, the vibration switch 6 is fixedly connected to the outside of the second pipeline 7, a limiting housing 14 is fixedly connected to the inside of the second pipeline 7 at the connection of the vibration switch 6, and a vibration bead 13 is provided inside the limiting housing 14.

[0031] Specifically: The standby water pump 12 is a submersible pump;

[0032] The setting of the high plate and the low plate causes a height difference between the left and right sides of the sewage pump box 1;

[0033] If the water pump motor 2 fails or power is cut off, the UPS power supply 8 is usually connected to an external power supply and stores power. When the water level in the sewage pump tank 1 causes the second starting float 10 to start the standby water pump 12, the water in the sewage pump tank 1 is pumped out and conveyed through the second pipeline 7 into the main sewage pipe 4. And when conveying liquid in the second pipeline 7, the vibration bead 13 inside the limit housing 14 will be impacted, so that the side wall of the second pipeline 7 at the vibration bead 13 has relatively strong vibration, which will cause the vibration switch to start, and the sound and light alarm 5 will give an alarm, enabling the staff to check the water pump motor 2 in time.

[0034] As Figure 1 shown: The upper end of the water outlet 9 is connected to a first pipeline 3, and the outlets of the first pipeline 3 and the second pipeline 7 are both connected to the main sewage pipe 4.

[0035] Specifically: The main sewage pipe 4 can transfer sewage to a designated location.

[0036] As Figure 1 and Figure 2 shown: The outside of the UPS power supply 8 is fixedly connected to the outer side wall of the sewage pump tank 1, and the sound and light alarm 5 is fixedly connected to the upper end of the sewage pump tank 1.

[0037] Specifically: The sound and light alarm 5 uses existing equipment on the market and is prior art.

[0038] As Figure 2 shown: The second pipeline 7 penetrates and is inserted into the upper high plate of the sewage pump tank 1, and the vibration switch 6 is fixedly connected to the outside of the second pipeline 7 located in the sewage pump tank 1.

[0039] Specifically: The vibration switch 6 can be closed through the vibration of the side wall when pumping water in the second pipeline 7.

[0040] As Figure 3 shown: The limit housing 14 is evenly provided with a number of through holes.

[0041] Specifically: The through holes can allow water to enter the inside of the limit housing 14, thereby impacting the vibration bead 13 inside the limit housing 14.

[0042] As Figure 2 shown: The lower part of the water pump housing is provided with a liquid inlet.

[0043] Specifically: The liquid inlet can communicate the inside of the water pump housing with the inside of the sewage pump tank 1, so as to pump the sewage inside the sewage pump tank 1.

[0044] As Figure 1As shown: Both the water pump motor 2 and the UPS power supply 8 are connected to an external power supply through wires.

[0045] Specifically: The water pump motor 2 and the UPS power supply 8 both use existing devices on the market and are both prior art.

[0046] As Figure 2 shown: The starting height of the first starting float 11 is less than the starting height of the second starting float 10.

[0047] Specifically: Both the first starting float 11 and the second starting float 10 use existing floats on the market, which act as switches. When the water level state enables the connected circuit to close, the water pump motor 2 and the standby water pump 12 will be correspondingly started to work.

[0048] Principle of use: When the normal power supply and the water pump motor 2 do not malfunction, the water pump motor 2 is powered by an external power supply device to make it work, that is, the water level inside the sewage pump box 1 enables the first starting float 11 to start the water pump motor 2 to work, driving the lifting impeller to rotate, thereby pumping the sewage inside the sewage pump box 1 out from the water outlet 9, and then transporting the sewage to the main sewage pipe 4 through the first pipe 3 and then transferring it to the set position;

[0049] If the water pump motor 2 malfunctions or there is a power outage, the UPS power supply 8 is usually connected to an external power supply, stores power, and then uses the stored power to supply power to the standby water pump. That is, in the event of a power outage, the standby water pump 12 can also be started. When starting the standby water pump 12, the water level inside the sewage pump box 1 enables the second starting float 10 to start the standby water pump 12, pumping the sewage inside the sewage pump box 1, transporting it to the main sewage pipe 4 through the second pipe 7, and when transporting the liquid inside the second pipe 7, it will impact the vibration bead 13 inside the limit housing 14, so that the side wall of the second pipe 7 at the vibration bead 13 has relatively strong vibration, thereby causing the vibration switch to start and the sound and light alarm 5 to give an alarm, so that the staff can check the water pump motor 2 in time.

[0050] The above are only specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features claimed in the present application.
