[0029] The specific structure of the water supply coupling system of the fire fighting truck and the corresponding technical effects brought by the specific structure will be described in detail below in conjunction with the patent drawings.
[0030] Please refer to Figure 1The utility model embodiment provides a kind of fire engine's water receiving coupling system 1 including water receiving vehicle, water supply belt 200 and water supply vehicle.The water receiving vehicle includes water receiving switch (not shown in drawing), first control module (not shown in drawing) and water receiving tank 110, water receiving tank 110 is provided with liquid level detection piece 111, water receiving tank 110 is provided with water inlet 112, water inlet 112 is equipped with first valve 120, water receiving switch, first valve 120 and liquid level detection piece 111 are connected with first control module communication, liquid level detection piece 111 is used to detect whether the liquid level in water receiving tank 110 is below first preset liquid level, one end of water supply belt 200 is connected with water inlet 112.
[0031] It needs to be explained that first control module can control the switch of first valve 120 according to the liquid level signal sent by liquid level detection piece 111.
[0032] Water supply vehicle (not shown in drawing) includes water supply switch, second control module and water tank, water tank is connected with water pump 310, water pump 310 is connected with driving element (not shown in drawing), driving element is used to control the start-stop of water pump 310, water pump 310 is provided with water outlet 311 connected with other end of water supply belt 200, water outlet 311 is equipped with second valve 330, water outlet 311 is provided with pressure switch 320, pressure switch 320 is located at the side of second valve 330 close to water supply belt 200, water supply switch, pressure switch 320, driving element and second valve 330 are connected with second control module communication.Second control module can control the switch of second valve 330 and driving element according to the pressure signal of pressure switch 320.
[0033] It can be understood that when water supply vehicle supplies water to water receiving vehicle, water pump 310 is opened, and at this time, first valve 120 and second valve 330 are both opened, and the water in water tank will enter water receiving tank 110 through water supply belt 200 under the action of water pump 310.
[0034] It needs to be explained that when water supply vehicle presses water supply switch, water receiving vehicle presses water receiving switch, liquid level detection piece 111 detects that the liquid level in water receiving tank 110 is in low liquid level state, first control module controls first valve 120 to open, water supply belt 200 is relieved, pressure switch 320 detects that the pressure of water supply belt 200 is reduced, second control module can start driving element, so as to control water pump 310 to start, and open second valve 330, so as to realize that water supply vehicle supplies water to water receiving vehicle.
[0035] When liquid level detection piece 111 detects that the liquid level in water receiving tank 110 is enough, first control module can control first valve 120 to close, at this time, water supply belt 200 is pressured, after pressure switch 320 detects that the pressure rises to preset pressure, second control module can close second valve 330, and close driving element, so that water supply vehicle is in standby state.
[0036] According to the above analysis, the water supply vehicle can control the water supply to the water receiving vehicle by controlling the start and stop of the second valve 330 and the driving member through the second control module according to the pressure signal of the pressure switch 320. The water receiving vehicle can control whether to receive the water supply of the water supply tank by controlling the opening and closing of the first valve 120 through the first control module according to the liquid level signal of the liquid level detection member 111. Therefore, the water supply and receiving coupling system 1 of the fire fighting vehicle provided in the embodiment can meet the normal water receiving of the water receiving vehicle and the normal water supply of the water supply vehicle even in a complex electromagnetic interference environment.
[0037] Alternatively, in some embodiments, the liquid level detection member 111 is a floating liquid level sensor, which is used to detect whether the liquid level in the water receiving tank 110 is lower than a first preset liquid level and whether it is greater than a second preset liquid level, the second preset liquid level being higher than the first preset liquid level. It can be understood that when the floating liquid level sensor detects that the liquid level in the water receiving tank 110 is lower than the first preset liquid level, it means that the liquid level in the water receiving tank 110 is in a low liquid level state, which represents that the water receiving tank 110 is in a water shortage state and needs to be supplied with water by the water supply vehicle. When the floating liquid level sensor detects that the liquid level in the water receiving tank 110 is higher than the second preset liquid level, it means that the liquid level in the water receiving tank 110 is sufficient and does not need to be supplied with water by the water supply vehicle.
[0038] Of course, in some other embodiments, the liquid level detection member 111 includes a first liquid level sensor and a second liquid level sensor in communication connection with the first control module, the height of the second liquid level sensor is greater than that of the first liquid level sensor, the first liquid level sensor is used to detect whether the liquid level in the water receiving tank 110 is lower than the first preset liquid level, and the second liquid level sensor is used to detect whether the liquid level in the water receiving tank 110 is greater than the second preset liquid level, that is, the liquid level in the water supply tank is detected by the two liquid level sensors.
[0039] That is, when the water supply vehicle presses the water supply switch, the water receiving vehicle presses the water receiving switch, and the liquid level detection member 111 detects that the liquid level in the water receiving tank 110 is lower than the first preset liquid level, the first control module controls the first valve 120 to open, the water supply belt 200 is depressurized, the pressure switch 320 detects that the pressure of the water supply belt 200 is reduced, and the second control module can start the driving member, so as to control the water pump 310 to start and open the second valve 330, thereby realizing the water supply of the water receiving vehicle by the water supply vehicle. When the liquid level detection member 111 detects that the liquid level in the water receiving tank 110 is higher than the second preset liquid level, the first control module can control the first valve 120 to close, at this time the water supply belt 200 is pressurized, the pressure switch 320 detects that the pressure rises to the preset pressure, the second control module can close the second valve 330, and the driving member is closed, so that the water supply vehicle is in a standby state.
[0040] In the embodiment, the water inlet 112 is provided with a water flow detection member 113, which is located at the side of the first valve 120 close to the water supply belt 200 and is in communication connection with the first control module. It can be understood that when the water supply vehicle presses the water supply switch, the water receiving vehicle presses the water receiving switch, and the liquid level detection member 111 detects that the liquid level in the water receiving tank 110 is lower than the first preset liquid level, the first control module controls the first valve 120 to open, the water supply belt 200 is depressurized, the pressure switch 320 detects that the pressure of the water supply belt 200 is reduced, and the second control module can start the driving member, so as to control the water pump 310 to start and open the second valve 330, so as to realize the water supply of the water supply vehicle to the water receiving vehicle. At this time, water will flow into the water inlet 112 through the water supply belt 200, and when the water flow detection member 113 detects the water flow of the water inlet 112, it will feed back the water receiving signal to the first control module, which represents that the water receiving is normal at this time. In other words, when the water flow does not detect the water flow in the water inlet 112, the water flow detection member 113 cannot send the water receiving signal to the first control module.
[0041] Optionally, in some embodiments, the water flow detection member 113 includes a conductive contact, and when the water flow output by the water supply tank passes through the water inlet 112, the electric contact is used to send a short-circuit signal to the first control module. It can be understood that the short-circuit signal can be understood as a normal water receiving signal. Of course, in some other embodiments, the water flow detection member 113 can be a flow sensor.
[0042] Optionally, in some embodiments, the water inlet 112 is provided with a first flow sensor, which is located at the side of the first valve 120 close to the water supply belt 200 and is in communication connection with the first control module. The first flow sensor is used to detect the water inflow of the water inlet 112, so as to facilitate the operation personnel to observe the water inflow of the water receiving tank 110 in time.
[0043] Optionally, the water outlet 311 is provided with a second flow sensor, which is located at the side of the second valve 330 close to the water supply belt 200 and is in communication connection with the second control module. The second flow sensor is used to detect the water outflow of the water outlet 311, so as to facilitate the operation personnel to observe the water outflow of the water supply tank in time.
[0044] According to the above setting, under the condition that the wireless communication equipment is not affected, the operation personnel of the water supply vehicle and the water receiving vehicle can judge whether the water leakage occurs in the water supply belt 200, the interface between the water supply belt 200 and the water inlet 112 and the interface between the water supply belt 200 and the water outlet 311 according to the comparison of the water outflow and the water inflow.
[0045] It should be noted that in some embodiments, the water supply vehicle can also serve as the water receiving vehicle of the rear vehicle, and the water receiving vehicle can also serve as the water supply vehicle of the front vehicle, that is, the water receiving vehicle is also provided with a water supply switch in communication connection with the first control module, and the water supply vehicle is also provided with a water receiving switch in communication connection with the second control module.
[0046] For example, when the water supply switch and the water receiving switch of the water supply vehicle are turned on at the same time, it means that the water supply vehicle needs to supply water to the front vehicle and at the same time receive water supply from the rear vehicle. When the water receiving switch and the water supply switch of the water receiving vehicle are turned on at the same time, it means that the water receiving vehicle not only needs water supply from the rear vehicle but also needs to supply water to the front vehicle.
[0047] In optional embodiments, when the series of fire vehicles changes, the water supply will produce a certain pressure drop or pressure increase, and then the water supply situation, at this time, the water supply end can make the second control module control the speed of the driving member to increase or decrease according to the pressure signal detected by the pressure switch 320, so as to ensure the constant pressure of the water supply.
[0048] Optionally, in some embodiments, in order to stably connect the water supply belt 200 with the water inlet 112 of the water receiving vehicle, the water supply belt 200 is stably connected with the water outlet 311 of the water pump 310. The two ends of the water supply belt 200 are provided with mounting flanges, the water inlet 112 is provided with a first flange, the water inlet 112 is sealingly connected with the mounting flange at one end of the water supply belt 200 through the first flange, and the water outlet 311 is provided with a second flange, the water outlet 311 is sealingly connected with the mounting flange at the other end of the water supply belt 200 through the second flange.
