Technical Field

The invention relates to the technical field of special automobile manufacturing, in particular to a storage battery heating system for a snow sweeper.

Background

the snow sweeper is mostly used in the north, the extremely cold weather with the temperature below-30 ℃ often appears in winter in the north, the automobile is difficult to start under the environment of the extremely cold temperature of-30 ℃, the main reason is that starting lubricating liquid becomes thick, ignition is not easy to succeed in rotating speed when ignition is started, the other reason is that the density of electrolyte of a storage battery with too cold temperature becomes low, the discharge capacity of the storage battery is not large at the normal temperature, the storage battery is insufficient in power, once ignition is unsuccessful for the first time, the storage battery consumes a large amount of electric charges, the chemical reaction of the storage battery with the extremely cold environment is inhibited, the electric quantity cannot be supplemented, and the second start has no chance at all. Therefore, the starting of the automobile is difficult in extremely cold weather.

Disclosure of Invention

The invention aims to provide a snow sweeper battery heating system which can solve the problem that in the prior art, an automobile is difficult to start in extremely cold weather.

In order to solve the problems, the invention adopts the technical scheme that: this kind of snow sweeper storage battery heating system, including the controller, the controller air supply fan send hot-blast speed, hot-blast from the heater through the blast pipe admit air, the blast pipe passes through pipeline and storage battery case gas mixing cabin intercommunication, air supply fan sets up on the pipeline, storage battery case gas mixing cabin and storage battery installation cabin intercommunication be provided with temperature sensor in the storage battery installation cabin, temperature sensor with the controller electricity is connected.

In the above technical solution, a more specific solution may also be: and a throttle valve is arranged on the pipeline between the air supply fan and the exhaust pipe.

Further: the pipeline is communicated with the battery box gas mixing cabin through gas mixing cabin gas inlets, and the gas mixing cabin gas inlets are formed in four corners of the battery box gas mixing cabin.

Further: the storage battery box gas mixing cabin is communicated with the storage battery installation cabin through a gas inlet, and the gas inlet is formed in the position on the upper side of the center line of the four sides of the storage battery installation cabin.

Further: the temperature sensors are arranged at four corners of the storage battery installation cabin.

Further: the bottom of the storage battery installation cabin is provided with an exhaust hole, and gas in the storage battery installation cabin is exhausted from top to bottom.

Due to the adoption of the technical scheme, compared with the prior art, the invention has the beneficial effects that: the invention is provided with the storage battery box gas mixing cabin, tail gas is introduced into the storage battery box gas mixing cabin, the tail gas enters the storage battery installation cabin after the temperature is fully mixed, the storage battery is heated to a certain temperature by the heater, the electronic activity of the storage battery is the most active, the discharging capacity of the storage battery reaches the optimal state, at the moment, the voltage and the discharging flow of the storage battery are values under the normal temperature state and are not influenced by the external low temperature, and the engine can be started smoothly.

Detailed Description

The invention is described in more detail below with reference to the following figures and examples:

The snow sweeper storage battery heating system shown in figure 1 comprises a controller 12, wherein the controller 12 controls the speed of air supply of an air supply fan 5, hot air enters air from a heater 1 through an exhaust pipe 2, the exhaust pipe 2 is communicated with a storage battery box gas mixing cabin 8 through a pipeline 4, the air supply fan 5 is arranged on the pipeline 4, the storage battery box gas mixing cabin 8 is communicated with a storage battery installation cabin 9, a temperature sensor 11 is arranged in the storage battery installation cabin 9, and the temperature sensor 11 is connected with the controller 12. A throttle valve 3 is provided in a pipe 4 between the blower fan 5 and the exhaust pipe 2. Pipeline 4 passes through gas mixing cabin air inlet 7 and battery box gas mixing cabin 8 intercommunication, and gas mixing cabin air inlet 7 is opened in four angles of battery box gas mixing cabin 8. The gas mixing cabin 8 of the storage battery box is communicated with the storage battery installation cabin 9 through a gas inlet 6, and the gas inlet 6 is arranged at the position on the upper side of the central line of the four sides of the storage battery installation cabin. The temperature sensors 11 are respectively arranged at four corners of the storage battery installation cabin. The bottom of the storage battery installation cabin 9 is provided with an exhaust hole, and the gas in the storage battery installation cabin 9 is exhausted from top to bottom.

When the system is started, the controller 12 starts the throttle valve 3 through the wire harness 13, meanwhile, the air supply fan 5 accelerates the supply of hot air, the hot air enters the air from the heater 1 through the exhaust pipe 2, the pipeline 4 is connected to the air inlet 7 of the gas mixing cabin of the battery box in the exhaust pipe 2, the gas in the gas mixing cabin 8 enters the battery installation cabin 9 from the air inlet 6, and the gas is subjected to heat exchange in the battery installation cabin 9. When the temperature sensor 11 arranged in the battery installation cabin 9 detects that the temperature is lower than 20 ℃, the signal of the temperature sensor 11 is transmitted to the controller 12, the controller compares the acquired digital quantity with a set value, and when the temperature is lower than the set value, the controller 12 transmits the signal to the air supply fan 5, and the air supply fan 5 accelerates air supply. When the temperature is higher than 25 ℃, the air supply fan 5 supplies air at a low speed, the temperature in the battery box is controlled to be 20-25 ℃, the temperature is the normal temperature working temperature of the battery 10, and at the moment, the electronic activity of the battery 10 is most active, and the discharging capacity of the battery 10 reaches the optimal state. The voltage and the discharge current of the battery 10 are both values at normal temperature and are not influenced by the external low temperature. The engine can be started smoothly. When the system is closed, the throttle valve 3 is closed and the blower fan 5 does not operate.

The invention utilizes the tail gas to heat the storage battery 10, and solves the problem that the automobile is difficult to start in extremely cold weather.
