[0011] In a preferred embodiment, a handle is installed on the top of the threaded rod, and a lifting ring is installed on one end of the positioning plate.

[0012] In a preferred embodiment, a water collecting trough is provided at the bottom of the support beam, and a water outlet pipe is provided at the bottom of the water collecting trough.

[0013] Beneficial effects of the utility model:

[0014] When the device is used, if the battery catches fire after the collision test, the cylinder is started to drive the transmission rod to move horizontally. Under the action of the connecting rod, the mobile frame can be moved from a vertical position to a horizontal position. Then, the water pump draws water from the outside into the water tank along the water inlet pipe, and the high-pressure nozzle sprays water into the fire to extinguish the fire. The staff does not need to approach the burning battery, which greatly improves the work safety of the staff.

[0015] When conducting a collision test, the positioning plate can be placed between the two gantries so that its bottom contacts the battery pack. Then the handle is turned, and the pressure plate moves downward under the action of the threaded rod to fix the positioning plate. By fixing the positioning plate, the battery pack can be prevented from being displaced too much when impacted. BRIEF DESCRIPTION OF THE DRAWINGS
