Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing blankets, in particular to a fire extinguishing blanket for an electric bicycle shed. Background Art

[0002] A fire blanket, also known as a fire blanket, fire extinguishing blanket, fireproof blanket, fire blanket, flame retardant blanket, or escape blanket, is a fabric woven from glass fiber and other materials that has been specially treated. It can isolate heat sources and flames and can be used to extinguish oil pan fires or be draped over the body to escape.

[0003] When an electric bicycle is parked or charging in a carport, the battery is prone to internal short circuit and external short circuit. When an electric bicycle battery spontaneously ignites, a fire blanket is needed to extinguish the burning battery. After the existing fire blanket covers the fire source, the flames will continue to burn after contacting the air from both sides of the fire blanket, making it impossible for the fire blanket to quickly extinguish the flames. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a fire extinguishing blanket for an electric bicycle shed to solve the technical problem that after the current fire extinguishing blanket covers the fire source, the flames will continue to burn after contacting the air from both sides of the fire extinguishing blanket, making it impossible for the fire extinguishing blanket to quickly extinguish the flames.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a fire blanket for an electric bicycle shed, including a fire blanket body, a groove is opened at the bottom of the fire blanket body, a plurality of connecting pipes are connected to the top of the inner cavity of the groove, the outer sides of the plurality of connecting pipes are fixedly connected with an inverted U-shaped frame, the bottoms of the plurality of inverted U-shaped frames are fixedly connected with a support plate, a sealing plug is inserted in the connecting pipe, the bottom of the sealing plug is fixedly connected with a connecting plate, a thermosensitive glass ball is installed between the connecting plate and the support plate, the inner cavity of the thermosensitive glass ball is filled with expansion liquid, and the inner cavity of the fire blanket body is installed with a plurality of dry powder tubes, and the plurality of dry powder tubes are connected with the plurality of connecting pipes.

[0006] Preferably, counterweight rods are installed on both sides of the inner cavity of the fire blanket body, and the two counterweight rods have the same size and mass.

[0007] Preferably, the expansion liquid is ether.

[0008] Preferably, the friction force between the sealing plug and the connecting tube is smaller than the air pressure in the dry powder tube.

[0009] Preferably, the connecting pipe is a high temperature resistant pipe.

[0010] Preferably, the connection length of the connecting pipe, the inverted U-shaped frame and the supporting plate is smaller than the depth of the groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model combines a fire blanket body, a heat-sensitive glass ball, an expansion liquid, a connecting pipe, a dry powder tube, an inverted U-shaped frame, a supporting plate, a sealing plug and a connecting plate. When the battery of an electric bicycle spontaneously ignites, the fire blanket body is unfolded and laid on the outside of the spontaneously ignited battery, thereby isolating the heat source and flame of the spontaneously ignited battery. When the expansion liquid expands after being exposed to high temperature and exceeds the set expansion temperature, the outer heat-sensitive glass ball will break, and then the high-pressure dry powder in the dry powder tube will impact the supporting plate and spray the dry powder 360°, thereby extinguishing the flame of the spontaneously ignited battery, and then the fire of the battery can be quickly extinguished, further reducing the economic losses caused by the fire.

[0013] 2. The utility model increases the gravity on both sides of the fire blanket body by setting the counterweight rod, thereby ensuring that both sides of the fire blanket body are in contact with the ground, thereby improving the effect of the fire blanket body on isolating heat sources and flames.

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example 1: A fire blanket for an electric bicycle shed, see Figures 1 to 4The fire blanket body 1 comprises a fire blanket body 1, a groove 11 is provided at the bottom of the fire blanket body 1, a plurality of connecting pipes 21 are connected to the top of the inner cavity of the groove 11, the outer sides of the plurality of connecting pipes 21 are fixedly connected to an inverted U-shaped frame 31, the bottoms of the plurality of inverted U-shaped frames 31 are fixedly connected to a support plate 3, a sealing plug 35 is inserted in the connecting pipe 21, a connecting plate 34 is fixedly connected to the bottom of the sealing plug 35, a thermosensitive glass ball 32 is installed between the connecting plate 34 and the support plate 3, an inner cavity of the thermosensitive glass ball 32 is filled with an expansion liquid 33, the expansion liquid 33 is ether, and a plurality of dry powders are installed in the inner cavity of the fire blanket body 1 Tube 2, multiple dry powder tubes 2 are connected with multiple connecting tubes 21. When the electric bicycle battery spontaneously ignites, the fire blanket body 1 is unfolded and laid on the outside of the spontaneously ignited battery, so as to isolate the heat source and flame of the spontaneously ignited battery. When the expansion liquid 33 expands after being exposed to high temperature, when the set expansion temperature is exceeded, the external thermosensitive glass ball 32 will break, and then the high-pressure dry powder in the dry powder tube 2 will impact the support plate 3 to spray the dry powder 360°, thereby extinguishing the spontaneously ignited battery flame, and then the battery fire can be quickly extinguished, further reducing the economic losses caused by the fire.

[0021] For details, see Figure 3 , counterweight rods 4 are installed on both sides of the inner cavity of the fire blanket body 1, and the two counterweight rods 4 have the same size and mass. Through the setting of the counterweight rods 4, the gravity on both sides of the fire blanket body 1 can be increased, thereby ensuring that both sides of the fire blanket body 1 are in contact with the ground, thereby improving the effect of the fire blanket body 1 on isolating heat sources and flames.

[0022] It is worth noting that see Figure 4 The friction between the sealing plug 35 and the connecting pipe 21 is smaller than the air pressure in the dry powder tube 2, so as to ensure that the pressure in the dry powder tube 2 can flush out the sealing plug 35 and ensure that the dry powder can be sprayed out to extinguish the fire.

[0023] It is worth noting that see Figure 2 The connecting pipe 21 is a high temperature resistant pipe, which is used to prevent the connecting pipe 21 from being melted or damaged by high temperature and affecting the spraying of dry powder.

[0024] It is worth noting that see Figure 3 The connection length of the connecting pipe 21, the inverted U-shaped frame 31 and the supporting plate 3 is less than the depth of the groove 11, so as to prevent the supporting plate 3 from being placed outside the groove 11 and affecting the effect of the fire blanket body 1 in isolating the heat source and the flame.
