Device；The second pipe is equipped with electrodynamic pump, which is conducted to the deputy tank by the second pipe；It further include a control
Device, the controller are connected with the liquid level sensor and the electrodynamic pump, to realize that deputy tank automatically adds water.
It further, is respectively the first liquid level sensor and the second liquid level sensor there are two the liquid level sensors,
First and second liquid level sensor is set to up and down in the deputy tank, with the low-bit line and a high position for detecting deputy tank
Line.
Further, it is additionally provided with check-valves on the second pipe, which is to be led to by the additional water tank by direction
The deputy tank.
Further, the upper end of the cooling water tank and the deputy tank is respectively provided with a filling opening, the first pipe both ends point
It is not inserted in two filling openings；And in the deputy tank, which extends to the bottom of the deputy tank.
Further, which is set to the bottom of the additional water tank, and then the second pipe one end is conducted to the pair water
The filling opening of case, the other end are conducted to the electrodynamic pump, so that the electrodynamic pump accesses the second pipe.
The further technical solution of the utility model are as follows: the controller is the Vehicle Controller of fork truck；The liquid level sensor
With the Vehicle Controller communication connection.
Wherein, the mode which connect with the Vehicle Controller are as follows: the Vehicle Controller is electrically connected with a solenoid valve,
The solenoid valve accesses the power supply circuit of the electrodynamic pump, to realize the start-up and shut-down control to the electrodynamic pump.
The utility model has the advantages that the automatic adds water system of the cooling deputy tank of the forklift engine of the utility model, additional by being arranged
Water tank, additional water tank are connected to deputy tank by second pipe；Via height of water level in liquid level sensor detection deputy tank, in water
In the case that position is too low, controller starts electrodynamic pump, adds coolant liquid to the deputy tank, until reaching high water level, that is, realizes
Deputy tank coolant liquid is automatically replenished.
In further technical solution, using Vehicle Controller as the controller of the automatic adds water system, insertion is realized
Into whole vehicle control program, it is not required to additional electronic device, is operated more intuitive and convenient.
Detailed description of the invention
Fig. 1 shows the utility model embodiment structural schematic diagram.
Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in connection with fig. 1, this embodiment offers a kind of automatic adds water system of the cooling deputy tank of forklift engine, packets
Include cooling water tank 1, deputy tank 2 and additional water tank 7, in which:
The cooling water tank 1 is connected with deputy tank 2 by first pipe 12, specific: the cooling water tank 1 and the pair water
The upper end of case 2 is respectively provided with a filling opening, and then the both ends of the first pipe 12 are inserted in respectively in two filling openings；The water of radiation
The filling opening of case 1 is closed, and in the cooling water tank 1, which is set to the position of the filling opening；Meanwhile the pair
The filling opening of water tank 2 is also closed, but its filling opening is equipped with a conduction pipe 20, which is conducted to atmosphere, with
In exhaust or air-breathing；In the deputy tank 2, the end of the first pipe 12 extends to the bottom of the deputy tank 2, for dropping
Resorption coolant liquid in warm backward cooling water tank 1.
The additional water tank 7 is conducted to the deputy tank 2 by second pipe 72: it is electronic that the bottom of the additional water tank 7 is equipped with one
Pump 6；One end of the second pipe 72 is conducted to the filling opening of the deputy tank 2, and then the other end is conducted to the electrodynamic pump 6, so that
