Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to a hand-push type lithium battery-specific fire extinguishing device. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution. Lithium metal batteries generally use manganese dioxide as the positive electrode material and lithium metal or its alloy metals as the negative electrode material, and use a non-aqueous electrolyte solution. After the lithium batteries are manufactured, they need to be tested. Some lithium batteries are rechargeable. If overcharging occurs during charging tests and the external temperature is too high, the lithium battery may catch fire and explode. In this case, the factory needs to use a special fire extinguishing device to extinguish the fire. However, the existing lithium battery fire extinguishing devices often have certain shortcomings in use and need to be improved.

The opening of the slot 4 allows the pedal 5 to be hinged inside, enabling it to move at a certain angle. It should be noted that the pedal 5 is hinged by a movable clamp, and the setting of the rigid spring 6 allows the pedal 5 to return to its original position after being pressed down. The opening of the connecting slot 7 allows the connector 8 to be screwed into its interior. The setting of the screw 10 makes it easy to replace the wear-resistant block 9 after it has worn to a certain extent. When replacing the wear-resistant block 9, the worker unscrews the screw 10, then removes the wear-resistant block 9, replaces it with a new wear-resistant block 9, and then screws the screw 10 back on.

[0026] The support base 2 has a rotatable connecting rod 11 inside, and two handles 12 are fixedly connected inside the connecting rod 11. A connecting frame 13 is fixedly connected to the bottom end of the connecting rod 11, and a second roller 14 is connected inside the connecting frame 13 via a rotating shaft. The connecting rod 11 facilitates the installation and fixation of the handles 12, and the connecting frame 13, the first roller 26, and the second roller 14 make the overall movement of the base plate 1 easier to control.

[0027] Both the top and bottom of the tank body 3 are fixedly connected to a winding plate 27. A rubber hose 28 is wound around the surface of the winding plate 27. A nozzle 29 is fixedly connected to the bottom of the rubber hose 28, and a connector is fixedly connected to the top of the rubber hose 28. The winding plate 27 allows the rubber hose 28 to be easily wound around the surface of the tank body 3 when not in use. It should be noted that the winding plate 27 is symmetrically arranged, which facilitates better winding of the rubber hose 28. The nozzle 29 makes it easier for operators to use the tank body 3 to extinguish the fire of the lithium battery. It should be noted that the surface of the upper winding plate 27 is fitted with a rubber band to easily bind the nozzle 29, connector, and winding plate 27 together to prevent them from falling apart.

[0028] A connection port 30 is fixedly connected to the top of the tank body 3, and a connector is threaded into the inside of the connection port 30. The connection port 30 and the connector allow the rubber hose 28 to be connected to the tank body 3, facilitating subsequent firefighting operations.

[0029] Example 2:

[0030] Please see Figure 1 , Figure 3 and Figure 4 As shown, the support base 2 has a vertical groove 15 inside, and a connecting column 16 is arranged inside the vertical groove 15. A pulling frame 17 is fixedly connected to the top of the connecting column 16. A rotating ring is rotatably arranged on the surface of the pulling frame 17, and a handle 18 is fixedly connected to the surface of the rotating ring. Several insertion holes 19 are opened on both sides of the inner wall of the vertical groove 15, and a positioning block 20 is fixedly connected to the surface of the connecting column 16. The vertical groove 15 allows the connecting column 16 to slide inside it, and the pulling frame 17 fixes the rotating ring to its surface. It should be noted that a rotating rod is rotatably arranged inside the pulling frame 17, and the rotating ring is fixed to the surface of the rotating rod. The handle 18 makes it easy for the operator to pull or push the entire device.

[0031] A partition 21 is fixedly connected to the middle of the inner bottom wall of the positioning block 20. Compression springs 22 are fixedly connected to both sides of the partition 21. A plug-in block 23 is fixedly connected to the end of the compression spring 22 away from the partition 21. A limit plate 24 is fixedly connected to one side of the surface of the plug-in block 23. A pull strip 25 is fixedly connected to the top of the limit plate 24. The positioning block 20 allows the partition 21 to be installed and fixed. The partition 21 allows the two compression springs 22 to be installed and fixed. The plug-in block 23 and the compression springs 22 provide the plug-in block 23 with a certain compressive force. It should be noted that the plug-in block 23 penetrates the interior of the positioning block 20 until it contacts the inner sidewall of the plug-in hole 19. The limit plate 24 allows the pull strip 25 to be installed and fixed. The pull strip 25 allows the plug-in block 23 to move towards or away from each other.

[0032] The top of the positioning block 20 has a horizontal groove, and the pull bar 25 passes through the inside of the horizontal groove. The horizontal groove provides the pull bar 25 with a certain amount of space when it moves.

[0033] The working principle of this utility model is as follows: When the lithium battery catches fire, the worker stands on the base plate 1 with one foot and then continuously steps on the ground with the other foot, causing the base plate 1 to move forward. At the same time, the worker firmly grips the handle 12 with both hands and controls the movement direction of the base plate 1 through the second roller 14. At this time, the first roller 26 and the second roller 14 rotate simultaneously, causing the base plate 1 to move continuously until it reaches the position of the lithium battery fire. Then, the worker forcefully steps down on the pedal 5 with the other foot. At this time, the other end of the pedal 5 moves downward through the hinge point, and the steel spring 6 is stretched downward, causing the wear-resistant block 9 at the bottom of the pedal 5 to contact the ground, thus slowing down the base plate 1. Then, the worker screws the connector into the connector 30 and opens the valve on the top of the canister 3, allowing the dry powder inside the canister 3 to be sprayed out through the rubber hose 28 and the nozzle 29. The worker uses the nozzle 29 to adjust the dry powder... The direction of powder spraying and the connector can be pre-connected to the connector 30 for easy direct use at the fire scene. Generally, when the distance is relatively short, the staff can pull the handle 18 to move the entire device to the appropriate position before extinguishing the fire. When the height of the handle 18 needs to be adjusted, the staff can use the positioning block 20 to press the two pull strips 25 toward each other. At this time, the two limit plates 24 move toward each other, and then the compression spring 22 is compressed. Then the plug block 23 disengages from the inside of the plug hole 19. At this time, the staff can adjust the position of the positioning block 20 upward until it moves to the appropriate position. Then the staff can stop pressing the pull strips 25, and then the compression spring 22 returns to its original position, so that the plug block 23 is inserted into the corresponding position of the plug hole 19, thereby fixing the positioning block 20. At this time, the handle 18 is fixed, which makes it easy for the staff to pull the entire device to the appropriate position.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
