Description

Technical Field

[0001] The utility model relates to the technical field of tractors, in particular to a tractor driven by an extended-range power supply based on a methanol generator. Background Art

[0002] With the development of technology, as well as the country's attention to agricultural mechanization and the support of relevant policies, the pace of the development of agricultural tractors towards electrification and intelligence has been further accelerated, and the functional requirements and endurance of agricultural machinery have also been continuously improved. Among them, a tractor driven by an extended-range power supply based on a methanol generator is a new type of fuel-electric tractor, and its main feature is to use a methanol generator as the energy source, and cooperate with an extended-range power supply drive system to achieve the power output of the tractor. When the tractor needs to travel, the methanol generator starts to work, outputs electric energy to the motor, and the motor drives the tires to rotate, pushing the tractor to travel, which can improve the operation efficiency of the tractor.

[0003] At present, when the tractor is plowing or towing some heavy objects, its traveling speed is slow, which will have a greater impact on the heat dissipation of the battery. Moreover, at this time, the power output by the battery is large, so the generated heat will also increase. If the battery is not cooled in time, the performance and service life of the battery will be reduced. Summary of the Utility Model

A cooling water tank is fixedly arranged inside the tractor body 1. The cooling water tank is a prior art and can cool the cooling water in a circulating manner. It further includes: a battery box 2. The bottom and the outer walls around the battery box 2 are both arc-shaped structures and protrude outward, which can improve the strength of the battery box 2. When being collided, the deformation of the battery box 2 can be reduced, and the use safety can be improved. A plurality of cooling blocks 4 are fixedly arranged inside the battery box 2. The number of the cooling blocks 4 is from two groups to twenty groups. Here, we preferably choose fifteen groups. Cooling channels 401 are opened in each of the fifteen groups of cooling blocks 4. Moreover, the fifteen groups of cooling blocks 4 are equally spaced and distributed on the inner bottom of the battery box 2. The two ends of the cooling channels 401 are respectively communicated with the cooling water tank. And heat dissipation fins 402 are fixedly arranged on the outer walls on both sides of the cooling blocks 4. Through the heat dissipation fins 402, the low temperature inside the cooling blocks 4 can be transferred into the battery box 2, increasing the contact area with the air inside the battery box 2 and improving the cooling effect. When in use, the cooling water in the cooling water tank is introduced into one end of the cooling channels 401 and then flows back into the cooling water tank from the other end of the cooling channels 401. The low temperature can be dissipated into the battery box 2 through the heat dissipation fins 402, thereby cooling the environment inside the battery box 2, enabling the battery pack to be at a lower temperature, ensuring the performance and service life of the battery pack, and improving the use effect; A top cover 3 is fixedly arranged on the top of the battery box 2 through bolts. A sealing gasket is arranged between the bottom end face of the top cover 3 and the top end face of the battery box 2, which can improve the sealing effect between the top cover 3 and the battery box 2, reduce the entry of dust or moisture into the battery box 2, improve the use safety, and a heat preservation layer is fixedly arranged inside the top cover 3 and the battery box 2. On the one hand, it can reduce the influence of the external environment on the inside of the battery box 2, and on the other hand, it can reduce the leakage of cold air inside the battery box 2, improving the use effect. And setting the cooling water inside the cooling blocks 4 can avoid the influence of the cooling water leakage on the battery pack and improve the use safety of the battery pack.

[0027] Referring to Figure 2 and Figure 3 , an inlet pipe 201 and a first shunt pipe 202 are opened inside one end of the battery box 2.

The fifteen groups of first branch pipes 203 are respectively communicated with one end of the corresponding cooling channels 401. When in use, the cooling water enters the first shunt pipe 202 through the inlet pipe 201 and then flows along the corresponding first branch pipes 203 into the cooling channels 401 respectively, which is convenient for introducing the cooling water into the cooling channels 401 and improving the use effect.

[0028] Refer to Figure 2 , at the other end of the battery box 2, a drain pipe 206 and a second shunt pipe are provided. One end of the drain pipe 206 is connected to the second shunt pipe. A plurality of groups of second branch pipes are fixedly arranged on the second shunt pipe. The number of the second branch pipes is two to twenty groups, preferably fifteen groups, corresponding to the cooling channels 401 one by one. And the fifteen groups of second branch pipes are respectively connected to the other ends of the corresponding cooling channels 401. When in use, the cooling water entering the cooling channels 401 will flow from the other ends of the cooling channels 401 to the second branch pipes, and then converge in the drain pipe 206, which is convenient for recycling the cooling water and improving the use effect.

[0029] Refer to Figure 2 and Figure 3 , at the tops of both ends of the battery box 2, a first groove 204 and a second groove are respectively provided. The other end of the liquid inlet pipe 201 is connected to the first groove 204, and the other end of the drain pipe 206 is connected to the second groove. And at both ends of the top cover 3, a first joint 302 and a second joint are respectively fixedly arranged. The first joint 302 and the second joint are respectively connected to the first groove 204 and the second groove. The first joint 302 is connected to one end of the cooling water tank through a water pump, and the second joint is connected to the other end of the cooling water tank. When in use, by fixedly arranging the first joint 302 and the second joint on the top cover 3, it is convenient to introduce cooling water into the cooling channels 401 and to recycle the cooling water, improving the use effect.
