[0037] See also Figure 1-3 As shown;
[0038] A battery module maintenance vehicle with emergency processing function is invented, comprising: a water tank 1, a flap group 2, and a fire curtain 3;
[0039] The top of the water tank 1 is open, and two flap groups 2 are symmetrically mounted on the opening of the water tank 1. One end of the flap group 2 is hinged to the water tank 1 through an axis, and the other end can be locked on the water tank 1 through a male and female latch 202. The fire curtain 3 is slidably connected to the water tank 1 and can be placed on the side or top of the water tank 1.
[0040] Among them, the linkage system flexibly connects the male and female latches 202 and the fire curtain 3 of the two flap groups 2, thereby triggering the external handle of the linkage system, driving the linkage system to unlock the male and female latches 202, and the flap group 2 flips around the axis to open the opening of the water tank 1, and at the same time drives the fire curtain 3 to be linked and placed on the top of the water tank 1 to cover the opening of the water tank 1. The battery module placed on the flap group 2 can fall into the water tank 1 through the opening. When the flap group 2 closes the opening of the water tank 1, the fire curtain 3 is placed on the side of the water tank 1.
[0041] For details, see Figure 2 As shown, the water tank 1 is a sealed box body with an open top, which is composed of five panels, namely, front, rear, left, right and bottom. A sufficient amount of saturated salt water is arranged in the box body;
[0042] A pair of guide rails 102 (such as Figure 3 As shown in the figure, the guide rail 102 is constructed to change the path upward to the top along the bottom edge of the side walls on both sides of the box body and extend toward the rear side wall until it is connected to the rear side wall. The structure is an inverted L-shaped structure. A fire curtain 3 is slidably connected between the two guide rails 102. The fire curtain 3 can slide along the guide rail 102 to cover the top opening position of the water tank 1, or move to the front side (the use side) of the water tank 1 to open the opening of the water tank 1, so that the work surface A of the water tank 1 is exposed;
[0043] A handle 4 is installed at one end of the water tank 1, and casters 5 are installed at the four corners of the bottom;
[0044] The front panel and the rear panel at the top of the water tank 1 are provided with shaft holes z1, z2, z3, and z4, which are used to axially connect the two flap groups 2 to form the work surface A of the maintenance vehicle. Figure 3 As shown;
[0045] See also Figure 4 As shown, the flap assembly 2 includes a flap 201, male and female latches 202, a retaining spring 203, a baffle 204, a spring 205, a guide tube 206 and a switch traction rope 207;
[0046] Flanged edges are provided on both sides of the flap 201, and one end of the flap 201 is provided with axial holes z5 and z6 that match the axial holes z1 and z2 and the axial holes z3 and z4 on the water tank. The axis penetrates and connects the water tank 1 and the flap 201, so that the flange 201 can flip around the axis. Two pairs of flanges f1, f2, f3, and f4 with holes are provided on the inner side of the other end of the flap 201. A pair of pin holes x5 and x6 are provided on the flap 201. The pin holes of the flange are coaxial with the axial holes of the flanges. Two male and female plugs 202 are symmetrically installed on the flap 201 through the inner flanges f1 to f4. In the initial state, the plugs of the male and female plugs 202 extend to the outside of the flap 201 through the pin holes x5 and x6 on the flange, and are inserted into the pin holes x1 and x2 and the pin holes x3 and x4 provided on the water tank 1 that match them.
[0047] The male and female plugs 202 are provided with two spring grooves at the plug end, and a connection point q1 of a switch traction rope 207 is provided at the other end;
[0048] A retaining spring 203 is fitted on the retaining spring groove c1 near the plug end. The retaining spring 203 is initially located between the pin hole x1 on the outer side of the flap 201 and the flange f1.
[0049] The male and female plugs 202 between the flange f1 and the flange f2 are matched with a retaining spring 203, a blocking piece 204 and a spring 205 from the outside to the inside. The retaining spring 203 is installed on the retaining spring groove c2. In the initial state, the retaining spring 203 is pressed onto the flange f1 by the blocking piece 204 pushed by the elastic force of the spring 205, and the other end of the spring 205 is pressed onto the flange f2. The plugs of the male and female plugs 202 extend out of the flap 201 through the pin holes x5 and x6 on the flange, locking the flap 201 to keep it in a horizontal state.
[0050] Two male and female latches 202 are symmetrically arranged on the flap 201. The installation principle of the other male and female latches 202 and related structural components is the same as the above structure, and will not be described again one by one;
[0051] A handle is provided at one end of the switch traction rope 207, and the other end extends into the water tank 1 through the openings k1 and k2 on the side of the water tank 1. The traction rope in the water tank 1 is divided into two paths to form a primary linkage of the linkage system. The two traction rope branches are respectively connected to the connection point q1 at the end of the male and female plug pins 202 through the guide tube 206 provided on the flap 201. The two male and female plug pins 202 are pulled out of the pin holes x1, x2 and the pin holes x3, x4 through the switch traction rope 207;
[0052] See also Figure 5 As shown, the linkage system also includes a transmission mechanism, which includes a shift block 208 and a shift piece 209, wherein the two male and female latches 202 on one flap group 2 are fixedly connected with the shift block 208, and the other flap group 2 is fixedly connected with a lock tongue 209 at a position corresponding to the shift block 208, and the shift block 208 is provided with a slot for accommodating the lock tongue 209, so that the lock tongue 209 is inserted into the slot of the shift block 208, so that the two male and female latches 202 on the two flap groups 2 are linked, thereby forming a secondary linkage of the linkage system, that is, in the initial state, when the two flap groups 2 are on the upper plane of the water tank 1 at the same time, the switch traction rope 207 handle on one side of the water tank 1 is pulled, and the four male and female latches 202 installed on the two flap groups 2 move synchronously, and the two flap groups 2 are opened synchronously.
[0053] See also Figure 6 As shown, the linkage system also includes a fire curtain traction rope 302, one end of which is installed on the installation point m1 set on the fire curtain 3, and the other end enters the water tank through the circular hole y1 set at the upper end of the water tank 1, and is connected to the connection point t1 set at the front end of the flap 201 to form a three-level linkage of the linkage system. That is to say, when the flap 201 is opened, the fire curtain 3 is driven to close the opening of the water tank 1 to quickly isolate the danger.
[0054] A self-locking buckle male head 301 is arranged on the top of the fire curtain 3, which can be locked with the self-locking buckle female head 101 arranged on the top of the water tank 1.

[0064] The switch traction rope 207 pulls a pair of male and female latches 202 on the flap group 2 connected thereto, and the pair of male and female latches 202 in turn drives a pair of male and female latches 202 on another flap group 2, and the four male and female latches 202 move synchronously into the water tank 1;
[0065] When the four latches on the flap assembly 2 are simultaneously disengaged from the pin holes on the water tank 1, the flap assembly 2 will flip downward around the rotation axes on both sides under the action of its own gravity and the gravity of the battery module;
[0066] On the one hand, the battery module falls into the water tank 1 and is immersed in saturated salt water, the air is isolated, the temperature is lowered, and the spontaneous combustion problem is effectively dealt with;
[0067] On the other hand, the flap group 2 flips downward, driving the fire curtain traction rope 302 to descend through the connection point t1 on the flap 201, and the other end of the fire curtain traction rope 302 moves upward under the action of tension, and drives the fire curtain 3 to move upward quickly. Finally, the self-locking buckle male head 301 set on the top of the fire curtain 3 and the self-locking buckle female head set on the top of the water tank 1 are matched and locked to achieve the effect of isolating danger.
[0068] 4) The device is restored to its original state
[0069] a. Open the self-locking buckle on the fire curtain 3 to move the fire curtain 3 downward. If necessary, disconnect the connection between the fire curtain traction rope 301 and the flap group 2;
[0070] b. Take out the battery module inside the water tank 1;
[0071] c. Replace with new saturated salt water;
[0072] d. Pull the switch traction rope 207 to make the four male and female latches move synchronously toward the inside of the flap group 2;
[0073] e. Flip the flap assembly 2 to its initial horizontal state, loosen the switch traction rope 207, and insert the four male and female pins into the pin holes on the water tank 1.
[0074] The battery module maintenance vehicle with emergency treatment function can immediately immerse the battery module in saturated salt water to isolate the air and lower the temperature during the battery module inspection, maintenance and charging and discharging operations by maintenance personnel. If the battery spontaneously ignites and catches fire, the battery module can be treated urgently.
[0075] The battery module maintenance vehicle with emergency processing function has the following beneficial effects:
[0076] 1) No damage will be caused to other equipment when handling the self-igniting battery module;
[0077] 2) Fire curtains can protect on-site operators immediately when handling self-igniting battery modules;
[0078] 3) The whole is made of stainless steel, which is not easy to corrode, durable and can be used repeatedly;
[0079] 4) The self-igniting battery module is placed in saturated salt water and the fire is extinguished by the principle of asphyxiation, which is efficient and environmentally friendly;
[0080] 5) The structure is cleverly designed, easy to operate, safe and efficient;
