Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Example 1

[0035] An automatic pumping system for a sewage tank includes a sewage tank 1, a submersible pump 2, a level controller 3, and a limiting structure 4.

[0036] Wastewater tank 1 is connected to the dehumidifier drainage pipe and is used to collect wastewater discharged from each dehumidifier. Submersible pump 2 is installed in wastewater tank 1 and connected to a wastewater drainage pipe. When started, it can discharge the wastewater collected in wastewater tank 1 through the wastewater drainage pipe. Liquid level controller 3 is connected to submersible pump 2 and is used to control the opening and closing of submersible pump 2.

[0037] Specifically, the level controller 3 includes an upper limit water level detection component 31 and a lower limit water level detection component 32 that extend into the sewage tank 1. When the sewage level in the sewage tank 1 reaches the sensing probe of the upper limit water level detection component 31, the level controller 3 controls the submersible pump 2 to start pumping water. When the sewage level in the sewage tank 1 drops below the sensing probe of the lower limit water level detection component 32 and loses contact with the probe, the level controller 3 controls the submersible pump 2 to shut down and stop pumping water.

[0038] Furthermore, in this embodiment, the sewage tank 1 is also provided with a limiting structure 4 that can limit the upper limit water level detection component 31 and the lower limit water level detection component 32.

[0039] Example 2

[0040] A sewage tank sensor-activated automatic pumping system, such as Figures 2-3 As shown, the limiting structure 4 includes a horizontal limiting structure 41 and a vertical limiting structure 42. The horizontal limiting structure 41 is used to horizontally limit the upper limit water level detection component 31 and the lower limit water level detection component 32, preventing them from shifting under the action of water flow and causing height changes, thus improving the accuracy of water level detection. The vertical limiting structure 42 is used to vertically limit the upper limit water level detection component 31 and the lower limit water level detection component 32, preventing them from moving up and down under the action of external forces, thus improving the accuracy of water level detection.

[0041] The rest is the same as in Example 1.

[0042] Example 3

[0043] In this embodiment of a sewage tank automatic pumping system, the limiting structure 4 further includes a ground wire horizontal limiting structure 43 and a ground wire vertical limiting structure 44. The horizontal limiting structure 41 and the ground wire horizontal limiting structure 43 are hollow sleeves with water-permeable holes, and the vertical limiting structure 42 and the ground wire vertical limiting structure 44 are clamping members set on the top of the sleeves.

[0044] The liquid level controller 3 used in this embodiment is a fully automatic liquid level controller DF-96D, which includes an upper limit water level detection component 31, a lower limit water level detection component 32, and a ground wire 33. The upper limit water level detection component 31 includes an upper limit water level probe and an upper limit probe connection line connected to the upper limit water level probe. The lower limit water level detection component 32 includes a lower limit water level probe and a lower limit probe connection line connected to the lower limit water level probe. The ground wire 33 extends to the bottom of the sewage tank 1 and contacts the bottom of the sewage tank 1.

[0045] In this embodiment, the upper limit water level detection component 31, the lower limit water level detection component 32, and the ground wire 33 all extend into the corresponding sleeves and are fixed by clamping components.

[0046] The rest is the same as in Example 2.

[0047] Example 4

[0048] In this embodiment of a wastewater tank automatic pumping system, the sleeve is further provided with markings for differentiation. For example, the upper limit water level detection component 31 is marked with "Upper Water Level," the lower limit water level detection component 32 is marked with "Lower Water Level," and the ground wire 33 is marked with "Ground Wire," facilitating personnel differentiation. Furthermore, in this embodiment, multiple dehumidifier drainage pipes are connected to a main pipe, which is connected to the wastewater tank, and the wastewater drainage pipe is connected to the wastewater treatment device 6.

[0049] The rest is the same as in Example 3.

[0050] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
