The control device 9 includes a controller 5 and an electric appliance control unit 8 that are connected to each other, and the electric appliance control unit 8 connects and controls the output fluid path cutoff valve, the fourth fluid path cutoff valve 84, the fifth fluid path cutoff valve 85, the sixth fluid path cutoff valve 86, and the seventh fluid path cutoff valve 87, respectively. The controller 5 is connected with and controls the liquid pump 1, and the controller 5 is also used for receiving signals of the liquid level sensor 6.
The controller 5 controls the liquid pump 1 through the power takeoff 2, and the power takeoff 2 is respectively connected with the controller and the liquid pump 1. The power take-off 2 is connected to a power source 4 via a transmission 3. The liquid pump 1 is preferably a mechanical pump. The power source 4 is preferably a vehicle engine.
The embodiment 1 of the invention provides a liquid storage device, which further comprises an alarm 12 for liquid level warning, wherein the alarm 12 is connected with the controller 5.
Taking water as an example, embodiment 1 of the present invention provides a liquid storage device, which has the working principle:
firstly, the sprinkling operation with normal working condition
When the watering operation is to be performed, the power source 4 (engine) is started, the power of the power source 4 is transmitted to the power takeoff 2 through the transmission 3, then the controller 5 controls the power takeoff 2 to be switched on, the power of the power source 4 is output to the liquid pump 1 (mechanical pump) through the power takeoff 2, and the liquid pump 1 starts to work. At the same time, the electrical control unit 8 controls the fourth, sixth, and seventh liquid passage cutoff valves 84, 86, and 87 to be closed. And the electric control unit 8 controls the first, second, third, and fifth fluid passage cutoff valves 81, 82, 83, and 85 to open. The liquid in the liquid tank 7 flows into the fifth liquid path cut-off valve 85 through a part of the third line 16, then flows into the inlet of the liquid pump 1 through a part of the first line 14, and the liquid is pressurized by the liquid pump 1 and flows out from the outlet of the liquid pump 1, and the seventh liquid path cut-off valve 87 is closed, so that the liquid flows out from the outlet of the liquid pump 1 and further flows into the liquid output line 13. Finally, the liquid flows through the output liquid path stop valves and the nozzles on the output branch paths and is finally sprayed outwards.
Secondly, the working condition is that the liquid level is too low in the sprinkling operation process
In the watering operation process, if the water level in the liquid tank 7 is reduced to the set lowest liquid level, the liquid level sensor 6 sends the lowest signal of the liquid level to the controller 5, the controller 5 controls the alarm 12 to give an alarm, the electric control unit 8 disconnects the cutoff valve, meanwhile, the power between the cutoff power takeoff 2 and the liquid pump 1 is cut off, the liquid pump 1 stops working, and the liquid pump 1 is prevented from being damaged due to air suction.
Thirdly, the working condition is self-priming water adding
When the liquid pump 1 self-priming the liquid tank 7, the controller 5 controls the electric control unit 8 to open the sixth liquid path cutoff valve 86 and the seventh liquid path cutoff valve 87 and close the other cutoff valves, and at the same time, the controller 5 controls the power takeoff 2 to supply the power of the power takeoff 2 to the liquid pump 1, and the liquid pump 1 starts to operate. Thus, the liquid pump 1 sucks water through the second connector 11, the water is added into the liquid tank 7, and the water flow sequentially passes through the second connector 11, the first pipeline 14, the liquid pump 1, the seventh liquid path shut-off valve 87 and the liquid tank 7.
When the liquid tank 7 is filled with water to the highest liquid level, the liquid level sensor 6 feeds back the highest liquid level signal to the controller 5, and the controller 5 controls the alarm 12 to give an alarm to remind an operator that the water tank is full. The controller 5 controls the power takeoff 2, so that the power connection between the power takeoff 2 and the liquid pump 1 is cut off, the liquid pump 1 stops working, and the liquid tank 7 is prevented from overflowing to cause water resource waste. In this case, the second port 11 is a self-priming port.
Fourthly, adding water into pressurized water source (fire hydrant) under working condition
When the fire hydrant is used for adding water into the liquid tank 7, the controller 5 controls the electric control unit 8 to enable the fourth liquid path stop valve 84 to be opened and other liquid path stop valves to be closed, and the fire hydrant is connected to the first interface 10 to add water into the liquid tank 7. The water flow passes through the first connector 10, the fourth fluid path shut-off valve 84, the third fluid path 16 and the fluid tank 7 in sequence.
When the liquid tank 7 is filled with water to the highest liquid level, the liquid level sensor 6 feeds back the highest liquid level signal to the controller 5, and the controller 5 controls the alarm 12 to give an alarm to remind an operator that the water tank is full. At the same time, the controller 5 gives an instruction to the electrical control unit 8, and the controller 5 closes the fourth fluid-passage cutoff valve 84 through the electrical control unit 8.
The invention also provides a liquid storage vehicle comprising the liquid storage device, which comprises a vehicle body, wherein the liquid storage device is connected with the vehicle body. Other technical features of the liquid storage cart are the prior art and are not described herein. Preferably, the liquid storage cart may be a water sprinkler.
Example 2
The present embodiment is different from embodiment 1 in that:
the liquid pump 1 is an electric liquid pump. The liquid pump 1 is powered by electricity, and the controller 5 can directly control the operation of the liquid pump 1 through a control signal.
The foregoing is merely a preferred embodiment of this invention, which is intended to be illustrative, and not limiting. The structure, the connection mode and the like of all the components in the invention can be changed, and the equivalent transformation and the improvement on the basis of the technical scheme of the invention are not excluded from the protection scope of the invention.
