Description

Technical Field

[0001] The present invention relates to the technical field of storage batteries, and more specifically to a forklift storage battery with a self-checking function. Background Art

[0002] A forklift is a common loading tool in modern industrial or logistics handling systems. Among them, an electric forklift is a forklift powered by a battery. With the development of the economy and the progress of industry, people's demand for the application of electric forklifts is increasing, gradually replacing traditional manual handling and loading and unloading. Electric forklifts not only improve work efficiency, but also greatly reduce the labor intensity of staff.

[0003] Existing forklift batteries tend to generate a lot of heat after long-term use. If the heat cannot be dissipated in time, the battery performance will easily deteriorate. Moreover, the accumulated temperature is too high and will burn the battery or even cause an explosion, which poses a great safety hazard. In general, when the battery is maintained, the temperature is often checked when it is not in use. During use, it is difficult to monitor the internal temperature in real time. If the temperature is abnormal during use, it is difficult to maintain and service the battery in time, which greatly shortens the battery life. In addition, during operations such as loading, unloading and transportation, the forklift generates large vibrations, especially in harsh working environments, such as when the road surface in the working environment is not flat enough or frequent braking is required. The battery is easily impacted, and frequent impacts may even cause damage to the battery casing, affecting the battery life and increasing maintenance costs. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provide a forklift battery with a self-checking function.

[0007] The air flows in from the air inlet channel and the cooling fan generates a cooling airflow, which flows into the corresponding transverse channels from the air outlet through a plurality of L-shaped connecting channels, so that the cooling airflow is distributed more evenly.

[0008] Furthermore, a cylindrical air outlet pipe is installed at each air outlet hole of the base, and the side of the air outlet pipe has four strip-shaped air outlet grooves distributed in a circular shape and at equal intervals; air guide plates are installed in the transverse channel and the longitudinal channel.

[0009] The air is discharged through the strip-shaped air outlet slots of the air outlet duct, and the heat dissipation airflow is guided by the air guide plate, thereby achieving a better heat dissipation effect.

[0010] Furthermore, it also includes a detection unit, which includes a plurality of detection tubes, which are distributed in a rectangular array, the number of the detection tubes is equal to the number of the air outlet ducts and the two correspond one to one, a detection tube is installed at the top of each air outlet duct, and among the plurality of detection tubes corresponding to the same transverse channel, two adjacent detection tubes are connected by a transverse connecting rod, and among the plurality of detection tubes corresponding to the same longitudinal channel, two adjacent detection tubes are connected by a longitudinal connecting rod, and each intersection is provided with a plurality of arc-surrounding plates, and the detection tube at each intersection is abutted against the plurality of arc-surrounding plates at the intersection, a mounting plate is fixed in the detection tube, and a temperature sensor is installed on the mounting plate; the buffer frame, the arc-surrounding plate, the air outlet duct, and the detection tube are all made of metal materials, and the mounting plate is made of non-metallic materials.

[0011] Therefore, the detection tube can be well protected by the arc-surrounding plate and the buffer frame, and the temperature sensor in the detection tube can achieve good temperature measurement.

[0018] Furthermore, the buffer frame, the arc-surrounding plate, the air outlet pipe, and the detection tube are all made of copper-aluminum alloy material, and the mounting plate is made of plastic.

[0019] The copper-aluminum alloy material has good heat dissipation effect, thus facilitating heat dissipation.

[0020] Furthermore, the base and the surrounding frame are fixedly connected by bolts.

[0021] Furthermore, a plurality of top protrusions are fixed to the top of the enclosing frame, and the top protrusions are provided with hanging through holes.

[0022] Thereby, the lifting of the battery is facilitated by the top protrusion.

[0023] Furthermore, the battery unit is a lead-acid battery or a lithium battery, and a plurality of battery units are connected in series.

[0024] Furthermore, the multiple L-shaped connecting channels are not connected to each other.

[0025] Thereby, the multiple L-shaped channels can achieve a more uniform distribution of the heat dissipation airflow.

[0026] Furthermore, the top end of the detection tube is open, and the mounting plate is fixed to the bottom end.

[0027] This facilitates mounting of the temperature sensor via the mounting plate.

[0028] Furthermore, the top cover is circular.

[0029] Furthermore, the top of the enclosing frame has four mounting grooves, and each fixed horizontal plate cooperates with two of the mounting grooves.

[0032] Furthermore, the base has a plurality of bottom protrusions, and each bottom protrusion is fixedly connected to the surrounding frame by the bolts.

[0033] This makes it easier to fix the surrounding frame to the base.
