In order to solve the above problems, the present utility model provides a novel apparatus and device for storing batteries, the detailed structure and operation principle of which are further described below.

First embodiment

Referring to fig. 1 to 6, the present utility model provides a device 100 for storing batteries, which can extinguish fire in emergency situations, so that the batteries stored therein are more reliable and safer, and the device does not need to be additionally provided with a pipeline and a water pump, has a simple structure, occupies a small volume, and is more beneficial to transportation and storage.

The device 100 provided in this embodiment includes a body 110, a fire-fighting nozzle 130 and a tubular member 150, wherein the body 110 has a partition wall 115, the partition wall 115 divides the body 110 into a first chamber 111 and a second chamber 113, the first chamber 111 stores fire-extinguishing liquid therein, and the second chamber 113 is located at the lower side of the first chamber 111 and is used for accommodating at least one battery 200. The fire sprinkler 130 includes a cover 173 and a temperature sensing member 171. The fire fighting nozzle 130 is installed in an opening 116 formed in the partition wall 115 and has a through hole 131 for communicating the first chamber 111 and the second chamber 113. The cover 173 is disposed at the lower side of the through-hole 131 and covers and seals the through-hole 131. The temperature sensing element 171 abuts against the bottom side of the cover 173, the tubular element 150 abuts against the top side of the cover 173, a portion of the tubular element 150 is disposed in the first chamber 111, and the tubular element 150 is configured to: in case that the temperature of the second chamber 113 exceeds the safety threshold, the temperature sensing member 171 is separated from the cover 173, and the cylindrical member 150 pushes the cover 173 downward by the gravity of the cylindrical member 150, thereby allowing the fire extinguishing liquid to flow from the first chamber 111 to the second chamber 113 through the through hole 131.

In actual use, the battery 200 may be placed in the second chamber 113 for storage. Normally, the cover 173 abuts around the through hole 131 of the fire nozzle 130, thereby sealing the through hole 131, and the temperature sensing member 171 abuts on the bottom side of the cover 173. At this time, the first chamber 111 and the second chamber 113 are separated from each other, and the fire extinguishing liquid does not flow into the second chamber 113 through the through hole 131, so that the second chamber 113 remains relatively independent, and storage and transportation of the battery 200 are realized. When the battery 200 catches fire due to external force or internal cause, the temperature sensing member 171 is able to sense the fire and to disengage from the cover 173 when the temperature of the second chamber 113 exceeds the safety threshold, so that the support is lost below the cover 173, and at this time, the cover 173 remains fixed to the through-hole 131 by means of adhesion or internal stress only. After the temperature sensing member 171 is separated from the cover 173, the cylindrical member 150 abutting on the top side of the cover 173 can push the cover 173 downward by gravity so that the cover 173 is separated from the through-hole 131, thereby allowing the fire extinguishing liquid to flow from the first chamber 111 into the second chamber 113 through the through-hole 131 to extinguish the fire. In this embodiment, by providing the cylindrical member 150, the cover 173 can be smoothly pushed out of the through-hole 131, thereby punching the through-hole 131. This configuration enables, on the one hand, the extinguishing of the device 100 in case of emergency, making the battery stored in the device 100 more reliable and safer, and, on the other hand, the elimination of the need for additional piping and water pumps, thus resulting in a device 100 with a simple structure, a smaller volume, and more advantageous for the transportation and storage of the battery.

It is noted that the fire-extinguishing liquid in this embodiment may be a water-based fire-extinguishing liquid, which is inexpensive. In this embodiment, a certain volume of water may be stored in the first chamber 111, thereby extinguishing the fire in the battery 200 of the second chamber 113.

In the present embodiment, the volume of the first chamber 111 is half the volume of the second chamber 113. The first chamber 111 may be filled with the fire-extinguishing liquid, so that when all the fire-extinguishing liquid flows into the second chamber 113 through the through holes 131, at least half of the second chamber 113 may be filled, and the continuous fire-extinguishing and cooling effects on the battery 200 are ensured.

Specifically, in this embodiment, the cover 173 has a circular plate structure, and the size of the cover 173 is larger than the size of the through hole 131, so that the through hole 131 can be completely covered, and the through hole 131 can be sealed. The temperature sensing element 171 has a heat sensitive structure and is capable of sensing the temperature in the second chamber 113. After the battery 200 fires, the temperature within the second chamber 113 can rapidly rise and exceed a safety threshold. In this case, the temperature sensing member 171 can be rapidly separated from the cover 173, so that the cover 173 loses support, facilitating the cylindrical member 150 to smoothly push the cover 173 downward and separate the cover from the through hole 131.

In this embodiment, the cylindrical member 150 is a metal cylindrical member, and a supporting frame 151 is further disposed in the first chamber 111, where the supporting frame 151 is disposed at the through hole 131 and surrounds the through hole 131. The metal cylinder is received in the support bracket 151 for extending into the through hole 131 and abutting against the top end of the cover 173. In particular, the bowl may be an iron rod and have a density greater than the fire suppression liquid. The cylinder has a certain mass, for example, more than 50g, and is configured to push the cover 173 downward, so that the cover 173 is smoothly separated from the through hole 131. In addition, the length of the metal cylinder needs to be lower than the height of the first chamber 111 in order to facilitate loading of the metal cylinder. Alternatively, the material of the cartridge herein may be other denser metals, such as lead or other alloy materials.

It should be noted that, the support frame 151 in this embodiment is configured to support the metal cylinder to avoid the metal cylinder from toppling, and simultaneously enable the metal cylinder to always maintain a downward force to apply pressure to the top end of the cover 173. In addition, the bottom of the supporting frame 151 is lapped on the bottom wall of the first chamber 111 through the supporting legs, so that a hollow structure is formed at the bottom, and water flow can conveniently and smoothly enter the through hole 131.

It should be noted that, in order to avoid the blocking of the through hole 131 by the metal cylinder, the outer diameter of the metal cylinder in the present embodiment needs to be smaller than the inner diameter of the through hole 131. Alternatively, the metal cylinder may have a partially hollowed-out structure, so as to ensure that the fire extinguishing liquid can smoothly enter the second chamber 113 through the through hole 131.

In the present embodiment, the center of the cover 173 is provided with a protrusion 175, the protrusion 175 extends into the through hole 131, and the cylindrical member 150 abuts against the tip of the protrusion 175. Specifically, the protrusion 175 is integrally provided at the central position of the cover 173. When the cover 173 is covered at the through-hole 131, the protrusion 175 can extend into the through-hole 131 from just the underside of the through-hole, facilitating an alignment abutment between the barrel 150 and the protrusion 175. In addition, by providing the protrusion 175, the rapid positioning of the cover 173 is facilitated, ensuring that the cover 173 remains relatively fixed to the fire nozzle 130 in the horizontal direction. The quick installation of the cover 173 can be achieved by aligning the projection 175 with the through hole 131 in the actual installation, and the blocking effect of the cover 173 is also ensured.

In the present embodiment, the cover 173 is provided with a seal ring 177, and the seal ring 177 surrounds the through hole 131 such that the cover 173 seals the through hole 131. Specifically, a seal ring 177 is provided on an upper side surface of the cover 173. After the cover 173 is mounted in place, the seal ring 177 can be pressed against the periphery of the through hole 131, thereby further ensuring the sealing effect of the cover 173. In addition, the sealing ring 177 may also cause adhesion between the cover 173 and the through hole 131 due to compression of the sealing ring. Accordingly, the barrel 150 in this embodiment is configured to push the cover 173 downward.

In the present embodiment, the temperature sensing member 171 includes a glass bottle filled with liquid, and in the case where the temperature of the second chamber 113 exceeds a safety threshold, the glass bottle is ruptured by thermal expansion of the liquid. In particular, the liquid may be a material extremely sensitive to heat, such as kerosene or mercury. During the rise in temperature inside the second chamber 113, the liquid continues to expand by being heated, resulting in a continuous rise in pressure inside the carafe. After the temperature exceeds the safety threshold, the pressure of the glass bottle also exceeds the limit and then breaks, at this time, the lower part of the cover 173 loses support and can move downward under the gravity of the barrel 150, thereby disengaging from the through hole 131.

Alternatively, in other preferred embodiments of the utility model, the temperature sensing element 171 may also comprise a holding rod made of a heat sensitive material, for example a silicone rod, which is also able to melt in case the temperature of the second chamber 113 exceeds a safety threshold, which is also able to disengage from the cover 173, so that the cover 173 loses support.

The fire-fighting nozzle 130 includes a nozzle body 133, a connection arm 135, and an expansion portion 137, the nozzle body 133 being disposed in the partition wall 115, the connection arm 135 extending downward from the bottom of the nozzle body, the expansion portion 137 being disposed at the bottom end of the connection arm 135. One end of the temperature sensing element 171 abuts against the expansion portion 137, and the other end abuts against the cover 173. Specifically, the head main body 133 has a cylindrical shape and is disposed in the opening 116 in the partition wall 115, and the head main body 133 is joined to the partition wall 115. The two connecting arms 135 may be provided, and the two connecting arms 135 are respectively provided at two opposite sides of the bottom of the head main body 133 in the radial direction, the expansion portion 137 has a expander, and one end of the glass bottle is abutted against the center of the expansion portion 137, and the other end is abutted against the bottom center of the cover 173, thereby supporting the cover 173.

Referring to fig. 1, 2, 7 and 8, optionally, in the present embodiment, the second chamber 113 is provided with an exhaust hole 117 communicating to the outside at a sidewall 114 thereof, an exhaust baffle 119 is provided at an inner side of the sidewall 114, and the exhaust baffle 119 is located between the fire nozzle 130 and the exhaust hole 117. Specifically, vent 117 may be a plurality of through holes arranged in an array with side wall 114 adjacent to fire nozzle 130. In this way, on the one hand, heat dissipation inside the second chamber 113 can be realized, and on the other hand, a pressure relief effect can be realized, so that burst caused by sudden change of air pressure inside the second chamber 113 is prevented. The exhaust baffle 119 is bent and extended in the lower direction of the exhaust hole 117 on the sidewall, thereby separating the exhaust hole 117 from the fire-fighting nozzle 130, and avoiding the waste of fire-extinguishing liquid caused by the fire-extinguishing liquid sprayed from the fire-fighting nozzle 130 being sprayed to the outside through the exhaust hole 117.

In this embodiment, the body 110 is further provided with a loading and unloading cover 190, a loading and unloading opening is further provided on a side of the second chamber 113 away from the exhaust hole 117, a sealing rubber strip 191 is provided on a surface of the loading and unloading cover 190, the loading and unloading opening is selectively covered, and the loading and unloading cover 190 is detachably connected with the body 110. Specifically, through setting up dress and getting lid 190, can make things convenient for the loading and unloading of battery 200 to adopt joint strip 191 shutoff dress to get the mouth, can guarantee the sealed assembly effect of battery 200, and can avoid putting out a fire in-process fire extinguishing liquid to leak from the dress and getting the mouth.

In this embodiment, one edge of the loading lid 190 is connected to the body 110 by a hinge 193, and the other side is connected to the body 110 by a latch 195. Specifically, one edge of the loading lid is provided with at least two hinge parts 193, and the other edge is provided with at least two latches 195 by the hinge parts 193 being hinged with the body 110. The body 110 is provided with a projection provided corresponding to the latch 195, and the attachment cover 190 and the body 110 are fixed by the engagement of the latch 195 with the projection.

In this embodiment, the top side of the body 110 is also provided with a handle 197. Specifically, the handle 197 is a rotatable structure that allows, on the one hand, the handle 197 to be rotated to an upright position for easy gripping by a hand when the body 110 is lifted, and, on the other hand, the handle 197 to be rotated to a position to fit against the top surface of the body 110 when stacked for storage, thereby avoiding the handle 197 from being raised and taking up a large amount of space.

The working principle of the battery storage box 100 provided in this embodiment is as follows: when the battery 200 in the second chamber 113 is ignited, the temperature of the second chamber 113 is rapidly increased in a short time, the liquid in the glass bottle is continuously heated to expand, after the temperature of the second chamber 113 exceeds a safety threshold, the glass bottle is broken due to the heated expansion of the liquid, the cover 173 is no longer supported by the glass bottle, the cover 173 is pushed downwards under the gravity action of the metal cylinder, and is separated from the through hole 131, so that the fire extinguishing liquid in the first chamber 111 can smoothly flow into the second chamber 113 through the through hole 131 and be dispersed to the ignition point of the battery 200 under the action of the expander, and the fire is extinguished on the battery 200.

In summary, the present embodiment provides a device 100 for storing batteries, where the device 100 includes a body 110 and a fire nozzle 130. The body 110 is partitioned into a first chamber 111 in which the fire extinguishing liquid is stored and a second chamber 113 by a partition wall 115, and the second chamber 113 is located at a lower side of the first chamber 111 to accommodate the battery 200. The fire-fighting nozzle 130 further includes a cover 173 and a temperature sensing member 171, the fire-fighting nozzle 130 being installed in the opening 116 formed in the partition wall 115 and having a through hole 131 for communicating the first chamber 111 and the second chamber 113, the cover 173 being disposed at a lower side of the through hole 131 and covering and sealing the through hole 131, the temperature sensing member 171 being abutted against a bottom side of the cover 173, the apparatus further including a cylindrical member 150 abutted against a top side of the cover 173, a portion of the cylindrical member 150 being disposed in the first chamber 111; the barrel 150 is configured to: in case that the temperature of the second chamber 113 exceeds the safety threshold, the temperature sensing member 171 is separated from the cover 173, and the cylindrical member 150 pushes the cover 173 downward by the gravity of the cylindrical member 150, thereby allowing the fire extinguishing liquid to flow from the first chamber 111 into the second chamber 113 through the through hole 131.

Compared with the prior art, the battery storage box 100 provided in this embodiment can smoothly push the cover 173 to separate from the through hole 131 by arranging the cylindrical member 150, thereby punching the through hole 131, and preventing the blocking of the cover 173 and the through hole 131 from blocking the flow of the fire extinguishing liquid.
