EMBODIMENT

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] like Figure 1 As shown, the pneumatic dewatering pump includes a water outlet pipe 6, an air inlet pipe, a one-way valve, a water inlet, and an air inlet pipe located inside the tank 1. The tank 1 is divided into an upper tank 2 and a lower tank 3 by a partition 1-1. The upper tank 2 and lower tank 3 are equipped with the water outlet pipe 6 and the air inlet pipe b5. The portion of the water outlet pipe 6 located in the upper tank 2 has a bend 6-2. The upper tank 2 and lower tank 3 are respectively equipped with water inlets a2-1 and b3-1 on their sides. The upper tank 2 is equipped with an air inlet pipe a4. The air inlet pipe a4 and air inlet pipe b5 are connected to an external solenoid valve via pipelines. The control system includes a chip, a switch, and a control button. The system includes a pressure sensor 10, with a chip that can be FT60F123-RB. When groundwater flows into the upper tank 2 and lower tank 3 through inlet a2-1 and inlet b3-1, the solenoid valves discharge air into the air inlet pipe a4 and air inlet pipe b5. This increases the pressure inside tank 1, squeezing the water in the upper tank 2 and lower tank 3, causing it to drain from the bottom of the bend pipe 6-2 and the outlet pipe 6, respectively. This system can quickly drain the groundwater in the pit. A pipeline generator 11 is installed between solenoid valves a7 and b8, and a lithium battery pack 12 is installed between the pipeline generator 11 and the control system.

[0035] When the solenoid valve is working, compressed air passes through the pipeline generator 11 and drives the generator impeller, so that the generator has a stable 12V voltage output. When the voltage of the lithium battery pack 12 is lower than the safe voltage (driving the solenoid valve coil), the pipeline generator 11 will charge the lithium battery pack. Since the power generation of the pipeline generator 11 is greater than the power consumption of the solenoid valve coil, the energy consumption of the whole system can be self-sufficient during operation, eliminating the need for frequent battery replacement and other maintenance operations.

[0036] The top of the outlet pipe 6 is located outside the upper tank 2, and the bottom is located below the inlet b3-1 of the lower tank 3 in the horizontal direction. The bottom of the outlet pipe 6 is equipped with a one-way valve b6-1 that opens towards the inside of the outlet pipe 6. The bottom of the outlet pipe 6 is located below the inlet b3-1. In this way, when groundwater enters the lower tank 3 from the inlet b3-1, the water flow will flow towards the bottom of the lower tank 3, and the outlet pipe 6 can discharge the water. If it is located above the inlet b3-1, the groundwater needs to touch the bottom of the outlet pipe 6 before it can be discharged, which is relatively slow. The one-way valve b5-1 at the bottom of the outlet pipe can prevent the backflow of groundwater and ensure that it can only flow from the bottom to the top.

[0037] The elbow 6-2 in the upper tank 1 is in the shape of a "U", the bottom of the elbow 6-2 is below the horizontal direction of the water inlet a2-1, and the bottom of the elbow 6-2 is provided with a one-way valve a4-1 opening towards the inside of the elbow 6-2. The elbow 6-2 in the upper tank 2 is also provided with an elbow 6-2 for the outflow of underground water, so that the underground water in the upper tank 2 can be pressed out of the elbow 6-2, and the one-way valve a6-3 at the bottom of the elbow 6-2 can ensure that the underground water can only flow out of the upper part of the elbow 6-2, preventing the water in the elbow and the water outlet pipe from flowing back.

[0038] The bottom of the air inlet pipe b5 is located in the lower tank 3 near the partition 1-1, and the part of the air inlet pipe b outside the upper tank 3 is connected with a quick release valve b5-1. The quick release valve b5-1 is connected with the electromagnetic valve b8 through a pipeline, and the end of the air inlet pipe b5 is located above the lower tank 3 to avoid being close to the lower part, so that the water in the lower tank 3 can be pressurized to the maximum extent, preventing the water flow from entering the inside of the air inlet pipe b5. When the electromagnetic valve is depressurized, the quick release valve b5-1 can quickly release the air.

[0039] The air inlet pipe a is located in the upper tank 2 near the top, and the part of the air inlet pipe a outside the upper tank 2 is connected with a quick release valve a. The pipeline connected with the quick release valve and the electromagnetic valve b8 is also provided with a pressure sensor 10, and the pressure sensor 10 is connected with the control system. The end of the air inlet pipe a is located above the lower tank 3 to avoid being close to the lower part, so that the water in the lower tank can be pressurized to the maximum extent, preventing the water flow from entering the inside of the air inlet pipe a. When the electromagnetic valve is depressurized, the quick release valve a can quickly release the air in the tank, so that the pressure inside and outside the tank remains the same to avoid pressure difference. The pressure sensor 10 can sense whether there is water flow into the upper tank 2 to transmit the signal to the integrated circuit, so that the integrated circuit controls the opening of the electromagnetic valve.

[0040] The water inlet a2-1 of the upper tank 2 is provided with a one-way valve c2-2 opening towards the inside of the tank, and the water inlet b3-1 of the lower tank 3 is provided with a one-way valve d3-2 opening towards the inside of the tank. The one-way valves c2-2 and d3-2 on the water inlets a2-1 and b3-1 can prevent the water in the tank from flowing back, ensuring that the underground water only flows in and does not flow out.

[0041] The electromagnetic valve b8 is connected with the control system, the electromagnetic valve b8 is connected with the electromagnetic valve a7, the electromagnetic valve a7 is connected with the control system, and the electromagnetic valve a7 is connected with the air compressor 9. The pressure sensed by the pressure sensor 10 is converted into a signal and transmitted to the integrated circuit, and then the integrated circuit controls the electromagnetic valve a7 and the electromagnetic valve b8 to work to intake air into the tank.

[0042] The PC3 pin of the chip is connected with the pressure IN port of the pressure sensor 101, the pressure sensor 101 is grounded, the A port input end of the electromagnetic valve b8 is connected with the OUT3 port of the chip PC1, and the output end is connected with the upper tank body, the B port input end of the electromagnetic valve b8 is connected with the OUT4 port of the chip PC2, and the output end is connected with the lower tank body, the input end of the total air inlet of the electromagnetic valve a7 is connected with the OUT1 of the chip PA3, the output end A port is connected with the P port of the electromagnetic valve b8, and the input end of the total switch of the electromagnetic valve a7 is connected with the OUT2 of the chip PC0.

[0043] When the pressure sensor 10 senses the pressure difference, it proves that the underground water enters the tank body, then the chip controls the electromagnetic valve a7 to inhale air, and controls the electromagnetic valve b8 to exhale air, the electromagnetic valve a7 transmits the air input from the air compressor 9 to the electromagnetic valve b8, the electromagnetic valve b8 inputs the air from the A port into the upper tank body, and then after the air inlet setting time, the air is input from the B port into the lower tank body.

[0044] The switch switching key includes a starting key SW1, a water outlet time switching SW2 and a sleep time SW3 switching, the starting key SW1 is connected with the KEY1 of the chip PA2, the starting key SW1 is a backup key, the KEY1 of the chip can also be connected with the switch J1 in the external electric box, the switch J1 in the external electric box can be directly pressed to start the device, if the switch J1 in the external electric box fails, the starting key SW1 can be used as a backup to start, the water outlet time switching SW2 is connected with the KEY2 of the chip PA0, and the sleep time SW3 is connected with the KEY3 of the chip PA1, when the whole device needs to be started, the starting key SW1 is pressed, then the chip starts to work, according to the depth of the underground water, the water outlet time switching SW2 is pressed to change the air outlet time of the electromagnetic valve b8, if the underground water is not enough, the sleep time SW3 is pressed, and the whole device can sleep for a set time.

[0045] The chip's power supply terminal is connected to LEDs 1, 2, 3, 4, 5, and 6 via resistors R1, R2, R3, R4, R5, and R6 respectively. LEDs 1, 2, 3, 4, 5, and 6 are also connected to the chip's PA7, PA6, PA5, PA4, PC5, and PC4 respectively. LEDs 1-3 indicate the water output time, and LEDs 4-6 indicate the sleep time. The chip's power supply terminal is connected to the battery module. The chip's PA0 and PA1 are connected to pins KEY2 (pin 3) and KEY3 (pin 4) of the programming port. When the device needs to change its operating mode, such as changing the sleep time or water output time, a new code is input through the programming port, and the chip executes the new instruction. Pin 1 is connected to the power module, which is connected to the chip's VCC terminal. The chip's VCC terminal is also connected to a charging display module. When the overall circuit voltage is less than 22V, the diode will break down, causing it to light up and indicating insufficient power.

[0046] Working principle: such as Figures 2-13 As shown, first place the tank into the pit where water needs to be pumped, and press the switch J1 in the external electrical box. If it fails, press the start button SW1. Button SW1 acts as a safety device to prevent the entire device from malfunctioning if switch J1 in the electrical box fails. After starting, the chip starts working. The chip transmits a signal from OUT1 of pin PA3 to solenoid valve a7. Solenoid valve a7 starts air compressor 9 to supply air to it. Then solenoid valve a7 transmits the air to solenoid valve b8. Solenoid valve b8 is also started at the same time as the chip starts solenoid valve a7. The chip transmits a signal to port A of solenoid valve b8 through pin OUT3 of PC1. The coil of port A of solenoid valve b8 is energized, which means that port A of solenoid valve b8 is activated. The air transmitted from solenoid valve a7 is released from port A. The air travels along the pipeline through pressure sensor 10 and enters the upper tank 2 through quick discharge valve a4-1. At this time, groundwater has entered the tank body through inlet a2-1 of upper tank 2 and inlet b3-1 of lower tank 3. When the air from the inlet pipe a4 enters the upper tank 2, the pressure sensor 10 senses the air pressure greater than the set value, for example, the set value is 0.4Mpa, the pressure sensor 10 will feedback the signal from the PC3 port of the chip to the chip, the chip continuously captures the signal of the pressure sensor 10, proving that there is water in the upper tank 2 all the time, because the pressure in the upper tank 2 is greater than the air pressure outside the tank, so the water in the upper tank 2 is squeezed out from the elbow 6-2 and flows out from the water outlet pipe 6, when the air inlet time of the electromagnetic valve b8 to the upper tank 2 reaches the set value of the chip, for example, 5 seconds, then the A port coil of the electromagnetic valve b8 loses power and stops air inlet, the compressed air in the upper tank 2 is released through the R port of the electromagnetic valve b8, the B port coil of the electromagnetic valve b8 is powered, and the B port starts to inlet air to the lower tank 3, the air inlet pipe 2 inlet air to the lower tank 3, the pressure in the lower tank 3 is greater than the pressure outside the tank, and the water is pressed out from the water outlet pipe 6, when the B port air inlet time reaches the set value of 5 seconds, the B port coil loses power and stops air inlet, and the A port inlet air, so as to repeat until the water in the tank is exhausted. When the water in the tank is exhausted, the A port of the electromagnetic valve b8 inlet air to the upper tank 2, because there is no water to submerge the elbow 6-2 in the tank, so the air entering the upper tank 2 is quickly discharged from the elbow, at this time the pressure sensor 10 senses the air pressure less than the set value, the pressure sensor 10 cannot feedback the signal to the chip, the chip cannot capture the signal of the pressure sensor 10, indicating that there is no water in the upper tank, then the chip controls the electromagnetic valve a7 to close through the OUT2 of the PC0 port, when the water in the foundation pit is deep, the water outlet time switching SW2 can be pressed according to visual observation, after the chip receives the signal, the air inlet time of the electromagnetic valve b8 will be changed, and the corresponding indicator light will light up, when the sleep time of the device needs to be changed, the sleep time switching SW3 is pressed, after the chip receives the signal, the sleep time of the device will be changed, and the new sleep time will be transmitted, and the corresponding indicator light will light up, when the sleep time is over, the PA2 of the chip is automatically opened, that is, the device starts to operate.
