[0035] At present, the vehicle used for transferring new energy vehicles further expands the fire during the transfer process, and may also cause danger to the operator of the transfer vehicle.

[0036] The present application provides a forklift.

[0037] Please refer to Figure 1 In an embodiment of the present application, the forklift 100 comprises a vehicle body 1, a water tank 2, a pipeline assembly 3, a spray head 4 and a driving assembly 5; the vehicle body 1 comprises a fork 11; the water tank 2 is installed on the vehicle body 1 and is used for storing fire extinguishing agent; the pipeline assembly 3 has a water inlet and a water outlet, the water inlet is communicated with the water tank 2, and the water outlet is arranged below the fork 11; the spray head 4 is hinged to the pipeline assembly 3 and is communicated with the water outlet, and the spray head 4 and the fork 11 are arranged in a staggered manner in the left-right direction; the driving assembly 5 is drivingly connected with the spray head 4, so that the spray head 4 can rotate along the up-down direction axis.

[0038] The technical scheme of the present application stores the fire extinguishing agent in the water tank 2, and sprays the fire extinguishing agent from the nozzle 4 at the water inlet through the pipeline assembly 3. Since the fork plate is in abutment with the bottom of the vehicle, the pipeline assembly 3 is arranged below the fork plate and extends along the fork plate. On the one hand, the fork plate can block the fire for the pipeline assembly 3, and on the other hand, the farther the water outlet is from the fork plate in the up-down direction, the wider the range of the fire extinguishing agent sprayed by the nozzle 4. In order to prevent the fork plate from blocking the fire extinguishing agent from being sprayed to the bottom of the vehicle, the nozzle 4 is arranged in a staggered manner with the fork 11 in the left-right direction. When the fork 11 forks the vehicle on fire, the nozzle 4 arranged below the side of the fork 11 sprays the fire extinguishing agent towards the bottom of the vehicle. The opening position of the nozzle 4 is adjusted by the driving assembly 5, so that the fire extinguishing agent is sprayed to the fire source, thereby achieving the technical effect of suppressing the fire when the vehicle is transported.

[0039] In order to adjust the angle of the nozzle 4 and to realize the rotation of the nozzle 4 along the up-down direction axis, in an embodiment, the specific structure of the driving assembly 5 is that the driving assembly 5 further comprises a mounting plate 51, a motor 52, a first connecting piece 53 and a second connecting piece 54. The mounting plate 51 extends along the left-right direction and is fixedly arranged on one side of the pipeline assembly 3. The mounting plate 51 provides a mounting basis for the installation of the motor 52. The motor 52 is fixedly mounted on the mounting plate 51. One end of the first connecting piece 53 is fixedly connected with the end of the motor 52, and the rotation of the motor 52 drives the other end of the first connecting piece 53 to rotate around the up-down direction axis. One end of the second connecting piece 54 is fixedly arranged on the other end of the first connecting piece 53, and the other end is connected with the nozzle 4. Therefore, the rotation of the first connecting piece 53 drives the rotation of the second connecting piece 54 and the nozzle 4. If the nozzle 4 can only rotate along the up-down direction axis, the nozzle 4 is inclinedly mounted relative to the up-down direction, otherwise the rotation of the nozzle 4 cannot change the direction.

[0040] Since only the nozzle 4 is rotated along the up-down direction axis, the adjustment of the direction of the nozzle 4 has certain limitations. Therefore, in an embodiment, the second connecting piece 54 has an active stroke that can stretch and contract along the direction in which it extends. The second connecting piece 54 comprises an electric cylinder 541. By the stretching and contraction of the electric cylinder 541, the inclination angle of the nozzle 4 relative to the up-down direction can be adjusted, so that the nozzle 4 has a larger adjustment range.

[0041] Since the upper side of the mounting plate 51 is opposite to the bottom of the vehicle, in order to protect the motor 52 and the main body 5411 of the electric cylinder 541, the motor 52 and the main body 5411 of the electric cylinder 541 need to be installed below the mounting plate 51, so that the mounting plate 51 protects the motor 52 and the main body 5411 of the electric cylinder 541 from fire or debris. Specifically, the motor 52 is arranged below the first connecting piece 53, the connecting shaft of the motor 52 penetrates the mounting plate 51 and extends to the upper side of the mounting plate 51, and is connected with the first connecting piece 53. The mounting plate 51 is provided with an arc-shaped groove 511 corresponding to the movement path of the end of the first connecting piece 53 away from the motor 52. The electric cylinder 541 includes a main body 5411 and a telescopic rod 5412 mounted on the main body 5411. The first connecting piece 53 partially penetrates the arc-shaped groove 511 and is connected with the main body 5411. The telescopic rod 5412 penetrates the arc-shaped groove 511 and is rotatably connected with the spray head 4. Among them, the telescopic rod 5412 on the upper side of the mounting plate 51, the first connecting piece 53 and the mounting plate 51 are all metal parts that can withstand high temperature and are not easy to deform.

[0042] In order to effectively control the fire when the vehicle is transported, the maximum range of the sprayed fire extinguishing agent needs to be large enough to be sprayed to all parts of the bottom of the vehicle. The spray heads 4 are arranged in multiple in the front-rear direction, and the corresponding driving assemblies 5 are also arranged in multiple and are respectively drivingly connected with the multiple spray heads 4.

[0043] In order to make the fire extinguishing agent sprayed from the spray head 4 diffuse and obtain a larger fire extinguishing area, the spray head 4 has multiple water outlet pipes 41 and a center axis. The angle between the extension direction of the water outlet pipe 41 and the center axis is proportional to the distance from the extension direction of the water outlet pipe 41 to the center axis.

[0044] Since the best fire extinguishing effect can be obtained by treating the fire source, but the positions of the batteries of different vehicles are different, the position of the fire source needs to be known. In an embodiment, the forklift 100 further includes a sensor and a control device. The infrared sensor is mounted on the vehicle body 1 and is arranged towards the upper interval of the forks 11. The control device is electrically connected with the infrared sensor and the driving assembly 5 respectively. The infrared sensor finds the position of the fire source, and the control device drives the driving assembly 5 to deflect the spray head 4 towards the position of the fire source.

[0045] Since the pipeline assembly 3 is located in front of the gantry 12, the pipeline in front of the gantry 12 can be subjected to high temperature, so the pipeline in front of the gantry 12 is provided as a metal pipe 31, and since the lifting and lowering of the forks 11, the pipeline assembly 3 cannot be provided as a whole as a metal pipe 31, the pipeline assembly 3 comprises: a metal pipe 31 provided below the forks 11, and the water outlet is provided on the metal pipe 31; and a hose 32 connecting the metal pipe 31 and the water tank 2. Among them, the metal pipe 31 is in a position that can be subjected to high temperature, the hose 32 is arranged in a reasonable temperature interval, and the metal pipe 31 can be ensured to rise and fall with the forks 11.

[0046] Since the forks 11 need to be raised or lowered, the overall length of the hose 32 needs to be relatively long, and when the forks 11 are lowered to the lowest position, the excess length of the hose 32 needs to be stored to prevent the hose 32 from hanging down or interfering with other parts. In an embodiment, the forklift 100 further comprises: a rotating shaft 6, a torsional spring; the rotating shaft 6 is rotatably mounted on the vehicle body 1 along the axial direction; the torsional spring is arranged between the rotating shaft 6 and the vehicle body 1, and the torsional spring is arranged at two ends of the rotating shaft 6; the hose 32 is wound around the rotating shaft 6, one end of the hose 32 extends forward to communicate with the metal pipe 31, and the other end extends backward to communicate with the water tank 2. When the forks 11 are raised, the forks 11 move one end of the hose 32, overcome the elastic force of the torsional spring, make the rotating shaft 6 rotate, and make the hose 32 disengage from the rotating shaft 6; when the forks 11 are lowered, the rotating shaft 6 is rotated in the opposite direction under the elastic force of the torsional spring, and the hose 32 is wound on the rotating shaft 6 to be stored.

[0047] In order to ensure the safety of the operator of the forklift 100, the forklift 100 further comprises an explosion-proof glass 7, the vehicle body 1 comprises a gantry 12, the forks 11 are slidingly installed on one side of the gantry 12, and the explosion-proof glass 7 is fixedly installed on the other side of the gantry 12 opposite to the forks 11. The explosion-proof glass 7 separates the driver from the vehicle. The explosion-proof glass 7 not only blocks the fragments generated by explosion, but also blocks the flame relative to the protective net, and the explosion-proof glass 7 has a better observation field of view relative to the protective net.

[0048] The above description is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made under the technical concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
