Example 1:

the sewage lifting pump station with the full-automatic lifting pump controller shown in the attached drawings 1-7 in the specification comprises glass fiber reinforced plastics 14 used as a pump station body for storing sewage, wherein a water inlet 19 for introducing the sewage and a lifting device for lifting and discharging the sewage are arranged in the glass fiber reinforced plastics 14, the lifting device consists of two independent lifting pump units, each lifting pump unit comprises a submersible pump arranged at the bottom of the glass fiber reinforced plastics 14 and a drainage pipeline communicated with the submersible pump and used for lifting the sewage; the submersible pump is controlled to be disconnected by a controller, the controller comprises a floating ball 35 which is powered on by acquiring buoyancy F3 through sewage level rising and drives the submersible pump to work, and a counterweight ball 37 which is used for disconnecting the controller through losing buoyancy F3 through sewage level falling so that the submersible pump stops, and the position of the floating ball 35 is higher than that of the counterweight ball 37. The controller comprises a static pressing sheet 28 and an elastic pressing sheet 29, wherein a static contact 30 is fixedly connected to the static pressing sheet 28, and a movable contact 31 for clamping the static contact 30 is arranged on the elastic pressing sheet 29; the lower surface of one end of the elastic pressing sheet 29 close to the movable contact 31 is respectively hinged with a floating ball 35 and a counterweight ball 37 connected through a pull wire 36 through a floating rod 34; the floating ball 35 and the counterweight ball 37 are both placed in a liquid level pipe 26 which is fixedly arranged on the inner wall of the glass fiber reinforced plastic 14 and is provided with a plurality of through holes 27. The buoyancy rod 34 is hinged through a connecting ring 33 fixedly connected to the lower surface of the elastic pressing sheet 29. The floating rod 34 is hinged in the sense that the floating ball 35 can only move up and down in the liquid level pipe 26 all the time, and the larger the bending angle of the elastic pressing sheet 29 is, the included angle between the elastic pressing sheet 29 and the floating rod 34 is changed, so that the hinged arrangement does not influence the force transmission nor the up-and-down swing of the elastic pressing sheet 29. A spring 32 is also arranged between the static pressing sheet 28 and the elastic pressing sheet 29. The conduction of the submersible pump circuit is controlled through the contact of the static contact 30 and the movable contact 31, however, the static contact 30 is kept still all the time, the conduction and the disconnection of the submersible pump are realized through controlling the displacement of the movable contact 31, when the elastic pressing sheet 29 of the controller is in the state shown in figure 4, the state is a natural state and is also a disconnected state, at the moment, the submersible pump does not work, sewage is continuously injected into a pump station, namely the glass fiber reinforced plastic 14, because the water level does not reach the drainage water level, the floating ball 35 cannot be subjected to the buoyancy F3, after the sewage is continuously injected, the water level continuously rises until the floating ball 35 is subjected to the buoyancy F3 to move upwards, so that the floating ball 35 transmits the buoyancy F3 to the elastic pressing sheet 29 through the buoyancy rod 34, and along with the continuous rising of the liquid level, the buoyancy F3 borne by the floating ball 35 continuously increases until, at this time, the buoyancy F3 of the floating ball 35 reaches the maximum value and overcomes the elastic force of the compressed spring 32 to continuously push the elastic pressing piece 29 upwards, and further overcome the frictional resistance between the movable contact 31 and the stationary contact 30 until the movable contact 31 is firmly clamped on the stationary contact 30, when the movable contact 31 and the stationary contact 30 are in the closed state, the maximum buoyancy F3 generated by the floating ball 35 is greater than the sum of the maximum static friction force F between the movable contact 31 and the stationary contact 30, the gravity G1 of the floating ball 35, the rebound force F1 generated by the elastic pressing piece 29 and the elastic force F2 generated by the spring 32. The circuit of the submersible pump is conducted, the controller acts as a switch of the working circuit of the submersible pump, and the submersible pump starts to work and starts to drain water after being closed. With the water level decreasing, the buoyancy F3 applied to the floating ball 35 will decrease until it is not. In this case, in order to keep the submersible pump working continuously to achieve the effect of prolonging the single working time period of the submersible pump, it is necessary to keep the movable contact 31 and the stationary contact 30 from being separated all the time, so that when the movable contact 31 and the stationary contact 30 are in a clamped state, the maximum static friction force F generated by the movable contact 31 clamping the stationary contact 30 is greater than the sum of the gravity G1 of the floating ball 35, the rebound force F1 generated by the elastic pressing piece 29, and the elastic force F2 generated by the spring 32. Therefore, the movable contact 31 and the fixed contact 30 can still keep contact under the action of the buoyancy F3 without the floating ball 35 until the sewage level reaches the lowest water level, namely the preset stop drainage level. At this time, when the movable contact 31 and the fixed contact 30 are in the disconnected state, the sum of the gravity G2 of the counterweight ball 37 and the gravity G1 of the floating ball 35 is greater than the sum of the maximum static friction force F between the movable contact 31 and the fixed contact 30, the rebound force F1 generated by the elastic pressing piece 29, and the elastic force F2 generated by the spring 32. It should be noted that the counterweight ball 37 is a key structure of the disconnection controller, and the best setting is that the density is adjusted to be the same as the sewage density, that is, the counterweight ball 37 is in a suspension state when submerged by water, the elastic pressing sheet 29 is not acted, and only when the lowest water level is reached and the buoyancy F3 is lost, the gravity of the counterweight ball 37 can pull down the elastic pressing sheet 29. Because the floating ball 35 and the counterweight ball 37 are both arranged in the liquid level pipe 26 which is fixedly arranged on the inner wall of the glass fiber reinforced plastic 14 and is provided with a plurality of through holes 27, the normal work of the floating ball 35 and the counterweight ball 37 cannot be influenced no matter the sewage level is at any position, and the reliability is extremely high.

The top of the glass fiber reinforced plastic 14 is also fixedly provided with a motor cover 1 for shielding the driving device.
