DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] Please refer to Figure 1-2 , the present invention provides a technical solution: a multifunctional airbag pump, including a protective shell 6, an inner tube 4 is provided inside the protective shell 6, a water outlet nozzle 2 is provided at the upper end of the inner tube 4, and a water inlet nozzle 8 is provided at the lower end;

[0026] An airbag 5 is sleeved outside the inner tube 4, locking sleeves 7 are provided at both ends of the airbag 5, and the locking sleeves 7 are respectively locked and sealed with both ends of the inner tube 4;

[0027] An air inlet and outlet nozzle 1 is provided at the upper end of the protective shell 6, and the lower end of the air inlet and outlet nozzle 1 is connected to the airbag 5;

[0028] A water outlet check valve 3 is provided between the water outlet nozzle 2 and the inner tube 4, and a water inlet check valve 9 is installed between the water inlet nozzle 8 and the inner tube 4.

[0029] A filter screen 10 is provided at the lower end of the water inlet nozzle 8, and the filter screen 10 is located inside the protective shell 6.

[0030] A plurality of through holes are evenly provided near the lower end of the protective shell 6, and the through holes correspond to the filter screen 10.

[0031] When the air inlet and outlet nozzle 1 intakes air, the airbag 5 is in a compressed state under the action of air pressure. At this time, the water outlet check valve 3 opens, and the water inlet check valve 9 closes. The water in the airbag 5 flows out of the airbag pump through the inner tube 4, the water outlet check valve 3, and the water outlet nozzle 2; when the air inlet and outlet nozzle 1 exhausts air, the airbag 5 rebounds, and under the action of pressure, the water outlet check valve 3 closes, and the water inlet check valve 9 opens. Water flows into the airbag 5 through the filter screen 10, the water inlet check valve 9, and the water inlet nozzle 8, forming a water inlet and outlet circulation, and the water collection function can be realized.

[0032] A lower housing 15 is provided at the lower end of the protective shell 6, a transmitting circuit 12 is provided inside the lower housing 15, and the transmitting circuit 12 is connected to a water level measurement module, a well depth measurement module, and a drawdown module;

[0033] A receiving circuit 18 is provided near the upper end of the inner tube 4. The receiving circuit 18 transmits wireless signals with the transmitting circuit 12. The receiving circuit 18 is connected to a communication line 19. A scale line is provided on the communication line 19, and the communication line 19 is connected to the outside;

[0034] Among them, the water level measurement module includes an electrode 14. The electrode 14 is electrically connected to the transmitting circuit 12, and the electrode 14 is located below the transmitting circuit 12;

[0035] Among them, the well depth measurement module includes a magnet 16 and a pendant 17. The magnet 16 is fixed to the upper end of the pendant 17. The pendant 17 is located outside the lower end of the lower housing 15, and the pendant 17 is movably connected to the lower housing 15.

[0036] The lower housing 15 is provided with a through hole, and the through hole corresponds to the position of the electrode 14.

[0037] When it is necessary to measure the water level and well depth, the airbag pump is lowered into the water well. When the lower housing 15 touches the water surface, the electrode 14 undergoes a short - circuit phenomenon. This signal is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. At this time, the scale value on the graduated communication line 19 can be read to complete the water level measurement.

[0038] Continue to lower the airbag pump. When the airbag pump touches the bottom of the well, the pendant 17 first touches the bottom of the well and undergoes a relative displacement. The magnet 16 connected to it moves upward, reducing the distance from the transmitting circuit 12. The magnetic induction sensor on the transmitting circuit 12 senses the change in magnetic flux. This signal is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. At this time, the scale value on the graduated communication line 19 can be read to complete the well depth measurement.

[0041] When it is necessary to measure the drawdown, place the airbag pump underwater. The pressure signal generated by the pressure sensor 13 is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. When the water surface changes, the measured pressure value of the pressure sensor 13 will change. It is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. Then the drawdown change of the liquid level can be read, and the liquid level self - recovery linkage sampling can be realized according to the liquid level change and the airbag pump control system linkage.

[0042] The working principle and usage process of the present utility model:

[0043] When the air inlet / outlet nozzle 1 intakes air, the airbag 5 is in a compressed state under the action of air pressure. At this time, the water outlet check valve 3 opens, and the water inlet check valve 9 closes. The water in the airbag 5 flows out of the airbag pump through the inner tube 4, the water outlet check valve 3, and the water outlet nozzle 2; when the air inlet / outlet nozzle 1 exhausts air, the airbag 5 rebounds. Under the action of pressure, the water outlet check valve 3 closes, and the water inlet check valve 9 opens. Water flows into the airbag 5 through the filter screen 10, the water inlet check valve 9, and the water inlet nozzle 8, forming a water inlet and outlet circulation, which can realize the function of water extraction;

[0044] When the water level and well depth need to be measured, the airbag pump is lowered into the water well. When the lower housing 15 touches the water surface, the electrode 14 therein has a short - circuit phenomenon. This signal is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. At this time, the scale value on the graduated communication line 19 can be read to complete the water level measurement;

[0045] Continue to lower the airbag pump. When the airbag pump touches the bottom of the well, the pendant 17 touches the bottom of the well first and has a relative displacement. The magnet 16 connected to it moves upward, reducing the distance from the transmitting circuit 12. The magnetic induction sensor on the transmitting circuit 12 senses the change in magnetic flux. This signal is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. At this time, the scale value on the graduated communication line 19 can be read to complete the well depth measurement;

[0046] When the drawdown needs to be measured, the airbag pump is placed underwater. The pressure signal generated by the pressure sensor 13 is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. When the water surface changes, the pressure value measured by the pressure sensor 13 will change. It is processed by the transmitting circuit 12 and sent to the receiving circuit 18 through a wireless signal, and is uploaded to the ground equipment through the graduated communication line 19. Then the change in liquid level drawdown can be read, and according to the change in the liquid level, it can be linked with the airbag pump control system to realize self - recovery linkage sampling of the liquid level.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
