[0018] Embodiment 2 Referring to Figure 1 、 4 Figures 6 and 7, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment.

[0019] In this embodiment, the control box 310 includes a box body 311, a box door 312 hinged to the box body 311 through a hinge, and an observation window 313 installed at the upper end of the surface of the box door 312. The display 350 is fixed to the upper end of the inner cavity of the box body 311. The photovoltaic inverter 440 and the storage battery 450 are both fixedly connected to the inner wall of the box body 311.

[0020] The control box 310 and the bracket 410 are both fixed to the top of the cylinder body 110. The handrail 160 is located on one side of the inspection cover 120.

[0021] The ventilation assembly 170 includes an intake pipe 171 and an exhaust pipe 172 that are connected to both sides of the top of the cylinder 110, and a duct fan 173 installed at the top of the inner cavity of the cylinder 110. There are two duct fans 173, which are respectively connected to the intake pipe 171 and the exhaust pipe 172, and the input end of the intake pipe 171 is connected to the input end of the frequency converter 340.

[0022] As Figure 1 、 4 shown in Figures 6 and 7, the two duct fans 173 of the ventilation assembly 170 are respectively connected to the intake pipe 171 and the exhaust pipe 172. When the gas sensor 365 detects that the gas inside the cylinder 110 needs to be replaced, the frequency converter 340 controls the operation of the duct fan 173, inhales fresh air through the intake pipe 171, and discharges harmful gases through the exhaust pipe 172, thereby realizing ventilation and air exchange inside the cylinder 110. The solar panel 420 is fixed on the bracket 410, converts solar energy into electrical energy, and the MPPT controller 430 performs maximum power point tracking control on the output of the solar panel 420 to improve the power generation efficiency. The photovoltaic inverter 440 converts direct current into alternating current, a part of which is directly supplied to the ventilation assembly 170 and the control assembly 300 for use, and the other part is stored in the storage battery 450 for use when solar energy is insufficient. The control box 310 is used to provide protection and installation space for the PLC controller 320, the edge computing gateway 330, the frequency converter 340, the MPPT controller 430, the photovoltaic inverter 440, and the storage battery 450. The display 350 is installed at the upper end of the inner cavity of the box body 311 and is used to display the operation data of the pumping station in real time. The operation data can be read through the observation window 313, which is convenient for the inspection personnel to view.

[0023] Embodiment 3 Referring to Figure 1 、 2 Figures 4 and 5, this is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0024] In this embodiment, the water inlet assembly 130 includes an intake pipe 131 connected to the outside of the cylinder 110, a grille guide rail 133 fixed to the inner wall of the cylinder 110, and a crushing grille 132 installed on the surface of the grille guide rail 133 through a guide seat, and the crushing grille 132 is located at the connection between the intake pipe 131 and the cylinder 110.

[0025] There are multiple groups of coupling guide rails 280, and all of them are fixedly connected to the inner wall of the cylinder 110. The coupling guide rails 280 are used for lifting the first submersible pump 230 and the second submersible pump 240, and both the first submersible pump 230 and the second submersible pump 240 are installed on the surface of the coupling guide rails 280.

[0026] There are multiple sets of automatic couplers 270. The first submersible pump 230 and the second submersible pump 240 are both connected to the connecting pipe 260 through the automatic coupler 270. One end of the connecting pipe 260 away from the automatic coupler 270 is connected to the water outlet pipe 250. The connecting pipe 260 is fixedly connected to the pipe rack 220.

[0027] As Figure 1 , 2 , 4, and 5 show that sewage flows into the interior of the cylinder 110 through the water inlet pipe 131 of the water inlet assembly 130. The crushing grille 132 is installed at the connection between the water inlet pipe 131 and the cylinder 110, and can crush large particle impurities in the incoming sewage to prevent it from blocking subsequent equipment. The crushing grille 132 can be lifted through the grille guide rail 133 and in cooperation with an electric hoist or a winch for cleaning and maintenance. The first submersible pump 230 and the second submersible pump 240 can be conveniently overhauled and maintained by being lifted through the coupling guide rail 280. By using the automatic coupler 270, it can be connected to the connecting pipe 260, and the sewage is transported to the water outlet pipe 250 through the connecting pipe 260 and finally discharged from the pumping station. The pipe rack 220 plays a role in fixing the connecting pipe 260.

[0028] During use, sewage enters the interior of the cylinder 110 through the water inlet pipe 131. At the connection between the water inlet pipe 131 and the cylinder 110, the crushing grille 132 is installed on the grille guide rail 133 and can crush the sundries in the incoming sewage to prevent large particle sundries from affecting the operation of subsequent equipment. After the sewage enters the cylinder 110, it gathers in the sump 210. When the first liquid level sensor 362, the second liquid level sensor 363, or the third liquid level sensor 364 monitors that the liquid level reaches a certain height, a lifting action is triggered. The first submersible pump 230 and the second submersible pump 240 are connected to the connecting pipe 260 through the automatic coupler 270 under the guidance of the coupling guide rail 280. Then, the sewage is lifted to the water outlet pipe 250 through the connecting pipe 260 and discharged. The monitoring component 360 monitors various parameters of the pump station in real time. The flow sensor 361 monitors the sewage flow of the outlet pipe 250. The first liquid level sensor 362, the second liquid level sensor 363, and the third liquid level sensor 364 respectively monitor the liquid levels at different positions of the cylinder body 110 and the sump 210. The gas sensor 365 monitors the gas condition inside the cylinder body 110. The monitoring component 360 is connected to the edge computing gateway 330 through RS485. After the edge computing gateway 330 preliminarily processes the data, it communicates with the cloud management platform through the MQTT protocol. The cloud management platform then transmits the data to the central control terminal in the remote duty room through the WebSocket protocol, facilitating remote monitoring by the staff. At the same time, the edge computing gateway 330 is connected to the PLC controller 320 through RS485, and transmits the monitoring data to the PLC controller 320. The PLC controller 320 controls the output of the frequency converter 340 according to the preset program and the received data. The frequency converter 340 adjusts the operating states of the first submersible pump 230, the second submersible pump 240, and the ventilation component 170 according to the instructions of the PLC controller 320, achieving energy conservation and efficient operation. When the liquid level is low, the power of the submersible pump is reduced. When the gas sensor 365 detects that the concentration of harmful gases exceeds the standard, the ventilation volume of the ventilation component 170 is increased. The edge computing gateway 330 is also connected to the monitor 350 through the HDMI interface, and displays the monitoring data and the device operating status on the monitor 350, facilitating on-site staff to view; The duct fan 173 of the ventilation component 170 is respectively communicated with the intake pipe 171 and the exhaust pipe 172. When the gas sensor 365 detects that the gas inside the cylinder body 110 needs to be replaced, the frequency converter 340 controls the operation of the duct fan 173, inhales fresh air through the intake pipe 171, and discharges harmful gases through the exhaust pipe 172, realizing ventilation and air exchange inside the cylinder body 110; The solar panel 420 is fixed on the bracket 410, converts solar energy into electrical energy. The MPPT controller 430 performs maximum power point tracking control on the output of the solar panel 420 to improve the power generation efficiency. The photovoltaic inverter 440 converts direct current into alternating current. Part of it is directly supplied to the ventilation component 170 and the control component 300 for use, and the other part is stored in the storage battery 450 for use when solar energy is insufficient. Through real-time monitoring and energy-saving control, it can effectively solve the problems of lack of real-time monitoring and poor energy-saving effect existing in traditional underground integrated pump stations.
