Description

Technical Field

[0001] The invention belongs to the technical field of forklift batteries, and in particular relates to a forklift battery provided with a ventilation duct. Background Art

[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Forklifts are widely used in ports, stations, airports, cargo yards, factory workshops, warehouses, circulation centers and distribution centers, etc., and can enter cabins, carriages and containers to load and unload and carry palletized goods. They are indispensable equipment in pallet transportation and container transportation. Electric forklifts are widely used in indoor operations and other working conditions with high environmental requirements, such as medicine, food and other industries, because they are pollution-free and low-noise. As people pay more attention to environmental protection, electric forklifts are gradually replacing internal combustion forklifts and becoming an important tool.

[0003] Existing electric forklifts use batteries as their power source. The forklift battery pack is generally sealed when in use. When used in high-temperature areas, the internal heat cannot be dissipated, which will cause the temperature inside the battery box to rise, thereby reducing the battery life. In severe cases, it may cause serious consequences such as fire. Summary of the invention

[0004] The object of the present invention is to provide a forklift battery provided with a ventilation duct, so as to solve the problem in the above-mentioned background technology that the battery pack box is generally closed when in use, and the internal heat cannot be discharged when used in high temperature areas, which will cause the temperature inside the battery box to rise, thereby reducing the service life of the battery, and in severe cases may cause serious consequences such as fire.

[0005] To achieve the above object, the present invention provides the following technical solution: a forklift battery provided with a ventilation duct, comprising a support plate and a battery body arranged above the support plate, two support frames for supporting the battery body being symmetrically fixed on the surface of the support plate, an adjusting screw being rotatably connected to the surface of the support frame, and a pressing plate for fixing the battery body being threadedly connected to the outer wall of the adjusting screw;

[0006] A protective shell is installed on the surface of the support plate, and ventilation grooves are opened on both side outer walls of the protective shell, and ventilation pipes are movably connected in the ventilation grooves on both sides of the protective shell, and a dustproof net is installed in the ventilation pipe, and two positioning blocks are symmetrically fixed to the outer wall of one side of the ventilation pipe, a connecting column is fixed between the two positioning blocks, and the outside of the connecting column is movably connected with a cleaning plate for cleaning the dustproof net.

[0007] In a further embodiment, mounting holes are provided on both outer walls of the ventilation pipe, fixing sleeves are fixed in the mounting holes on both sides of the ventilation pipe, and fixing springs are provided in the fixing sleeves.

[0008] In a further embodiment, a limiting slider movably connected to the fixing sleeve is provided on one side of the fixing spring, a fixing pin is fixed to an outer wall of one side of the limiting slider, and a plurality of fixing grooves matching the fixing pin are provided in the protective shell.

[0009] In a further embodiment, two limiting holes are symmetrically opened on the surface of the pressing plate, and limiting columns fixedly connected to the support frame are movably connected in the limiting holes on the surface of the pressing plate.

[0010] In a further embodiment, a handle is fixed to the top of the adjusting screw, and grooves are formed on both side outer walls of the protective shell.

[0011] Technical effects and advantages of the present invention:

[0012] The forklift battery provided with a ventilation duct can quickly discharge the heat generated by the battery body from the protective shell through the two ventilation grooves provided on the protective shell and the ventilation duct, thereby reducing the temperature of the battery body. At the same time, the support frame supports the battery body, increases the distance between the support plate and the battery body, and enables air to pass through the bottom of the battery body, thereby further accelerating the heat dissipation speed of the battery body.

[0013] The dustproof net can prevent dust from entering the protective shell, thus preventing dust accumulation from affecting the heat dissipation of the battery body. At the same time, the detachable ventilation pipe, in conjunction with the movable cleaning plate, can clean the dustproof net by moving the cleaning plate, thus preventing dust from clogging the dustproof net and affecting the ventilation effect of the ventilation pipe.

[0014] By turning the adjusting screw, the pressure plate can be driven to move, and the height of the pressure plate can be adjusted according to the size of the battery body, so that battery bodies of different sizes can be fixed. The forklift battery with a ventilation duct can not only effectively dissipate the heat of the battery body, but also facilitate the cleaning of the dustproof net to ensure the ventilation effect of the ventilation duct.

[0031] Working principle:

[0032] When the forklift battery provided with the ventilation duct is in use, the two ventilation grooves provided on the protective shell 8 cooperate with the ventilation pipe 9 to perform the ventilation function, discharge the heat generated by the battery body 3 from the protective shell 8, and reduce the temperature of the battery body 3. At the same time, the support frame 2 supports the battery body 3, increases the distance between the support plate 1 and the battery body 3, and allows air to pass through the bottom of the battery body 3, further accelerating the heat dissipation speed of the battery body 3.

[0033] The dustproof net 10 blocks dust and prevents dust from entering the protective shell 8, thereby avoiding dust accumulation that affects the heat dissipation of the battery body 3. When the dustproof net 10 is blocked, the ventilation pipe 9 is taken out of the protective shell 8 by pulling the block, and the cleaning plate 16 is moved back and forth outside the connecting column 15 to clean the dustproof net 10 to avoid dust blocking the dustproof net 10 and affecting the ventilation effect of the ventilation pipe 9. After the dustproof net 10 is cleaned, the ventilation pipe 9 is placed in the protective shell 8, and the fixing spring 12 supports the limit slider and the fixing pin 13, so that the fixing pin 13 is inserted into the fixing groove of the protective shell 8 to fix the position of the ventilation pipe 9.
