Description

Technical Field

[0001] This invention relates to the field of fire emergency water supply equipment technology, specifically an emergency safety water supply device. Background Technology

[0002] With the rapid development of urban construction, building density is constantly increasing and building height is continuously rising. Complex scenarios such as industrial plants, chemical industrial parks, and narrow streets are becoming more common, placing higher demands on the timeliness, stability, and adaptability of fire emergency water supply. As an indispensable core equipment in fire rescue, the performance of fire emergency water supply devices directly affects rescue efficiency and the safety of personnel and property.

[0003] Traditional fire-fighting water supply equipment is bulky and heavy, relying on fire truck towing or fixed installation. In situations with blocked roads and complex terrain at fire scenes, it is difficult to transport and deploy quickly, hindering its timely arrival at the core of the fire to provide water supply. Some portable emergency fire-fighting water supply equipment lacks effective buoyancy, making it unable to stably draw water from the surface of flooded or waterlogged areas, thus failing to provide a continuous supply of water for firefighting. Furthermore, fire scenes often contain weeds, floating debris, and aquatic plants, easily clogging the water intakes of existing supply equipment and reducing water intake efficiency.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-10 An emergency safety water supply device includes a main support 1, and a water supply component 2 is installed on the top of the main support 1.

[0035] Water supply assembly 2 includes a micro-engine 201. An oil tank 202 and a filter element 203 are mounted on the outer wall of the micro-engine 201. A rotating shaft 204 is fixedly sleeved onto the power output shaft of the oil tank 202. An internal gear 220 is fixedly sleeved onto the outer edge of the rotating shaft 204. An external gear 221 meshes with the outer edge of the internal gear 220. A connecting rod 223 is mounted around the center of the external gear 221. A movable support arm 224 is movably sleeved onto the outer edge of the connecting rod 223. A telescopic arm 225 is movably connected to the end of the movable support arm 224 away from the connecting rod 223. A piston 226 is mounted on the end of the telescopic arm 225 away from the movable support arm 224. The outer edge of 26 is slidably connected to the outer shell 227. The outer edge of the micro engine 201 is provided with a gas storage pipe 230. The gas storage pipe 230 is connected to the outer shell 227 through an inflation pipe 228. An air intake pipe 231 is installed on the inner wall of the outer shell 227. Airbag 1 209 and airbag 210 are respectively installed on both sides of the main support 1. A flat plate 208 is installed on the inner wall of the main support 1. Airbag 1 209 and airbag 210 are installed on the flat plate 208. Airbag 1 209 and airbag 210 are connected to the air supply pipe 233 through a gas distribution pipe 235. The air supply pipe 233 is connected to the gas storage pipe 230.

[0036] In the above structure, the micro-engine 201 drives the rotating shaft 204 to rotate. The rotation of the rotating shaft 204 drives the internal gear 220 to rotate, which in turn drives the external gear 221 to rotate. The external gear 221, in turn, drives the connecting rod 223 to rotate. The connecting rod 223 can move closer to or further away from the outer shell 227. The rotation of the connecting rod 223 can drive the telescopic arm 225 and piston 226 to rotate within the outer shell 227 via the movable support arm 224. When the piston 226 moves towards the connecting rod 223, it can fill the outer shell 227 with air. When the piston 226 moves in the opposite direction to the connecting rod 223... When moving, the connecting rod 223 can compress the air in the outer shell 227, allowing the air in the outer shell 227 to enter the gas storage tube 230. The gas storage tube 230 stores a large amount of compressed air. When the equipment needs to be used, the compressed gas in the gas storage tube 230 inflates the first airbag 209 and the second airbag 210. The air in the gas storage tube 230 enters the first airbag 209 and the second airbag 210 through the air supply pipe 233 and the air distribution pipe 235, so that the first airbag 209 and the second airbag 210 can support the micro engine 201 and the water pumping shell 205. At this time, the entire device can float on the water surface to pump water in emergencies.

[0037] In a preferred embodiment: the bottom of the micro engine 201 is provided with a water pumping housing 205, the inner cavity of the water pumping housing 205 is provided with a water pumping impeller 2051, the water pumping impeller 2051 is fixedly connected to the rotating shaft 204, and the water pumping housing 205 is mounted on the micro engine 201 through a connecting bracket 222.

[0038] In the above structure, the rotating shaft 204 drives the water pumping impeller 2051 to rotate. The rotation of the water pumping impeller 2051 can draw water into the water pumping housing 205. The water in the water pumping housing 205 is discharged through the drain port of the water pumping housing 205, so that water can be obtained where it is needed. By installing the connecting bracket 222 on the micro engine 201 and then installing the water pumping housing 205 on the connecting bracket 222, there is a space between the water pumping housing 205 and the micro engine 201, so that the outer shell 227 can be set in this space. The outer shell 227 will not come into contact with water in this space, which improves the stability of the device operation.

[0039] In a preferred embodiment: the external gear 221 is movably connected to the connecting bracket 222, the outer shell 227 is mounted on the micro engine 201, and the outer wall of the gas storage tube 230 is fitted with a mounting bracket 240, which is mounted on the main support 1.

[0040] In the above structure, the connecting bracket 222 can limit the external gear 221, so that the external gear 221 can only rotate on the connecting bracket 222, and the external gear 221 can mesh with the internal gear 220. The gas storage tube 230 is mounted on the main support 1 through the mounting bracket 240, so that the mounting bracket 240 will not shake and will not move during inflation and deflation, thus improving the stability of the device on water.

[0041] In a preferred embodiment: airbag 1 209 and airbag 210 are connected by a split air pipe 235, an air supply pipe 233 is installed on the inner wall of the split air pipe 235, and an air supply valve 234 is installed on the outer wall of the air supply pipe 233.

[0042] In the above structure, the gas in the gas storage tube 230 first enters the gas supply tube 233, and then the gas in the gas supply tube 233 enters the gas distribution tube 235. The gas in the gas distribution tube 235 then enters the first airbag 209 and the second airbag 210, so that the first airbag 209 and the second airbag 210 can obtain gas. With the setting of the gas supply valve 234, the gas supply valve 234 mainly cuts off the gas path between the gas storage tube 230 and the gas distribution tube 235. When the middle of the first airbag 209 and the second airbag 210 needs gas, the gas supply valve 234 is in the closed state. When the first airbag 209 and the second airbag 210 need gas, the gas supply valve 234 is opened, so that the gas in the gas storage tube 230 enters the first airbag 209 and the second airbag 210 through the gas supply tube 233 and the gas distribution tube 235.

[0043] In a preferred embodiment: an inflation check valve 229 is installed on the outer wall of the inflation pipe 228, an inlet check valve 232 is installed on the outer wall of the inlet pipe 231, the connection ends of the inflation pipe 228 and the inlet pipe 231 to the outer shell 227 are both located at the end away from the movable support arm 224, and an exhaust check valve 239 is installed on the top of the gas storage pipe 230.

[0044] In the above structure, the inflation check valve 229 seals the gas in the gas storage tube 230, ensuring that the gas in the outer casing 227 can only enter the gas storage tube 230 through the inflation tube 228 and the inflation check valve 229. The gas in the gas storage tube 230 cannot enter the outer casing 227 through the inflation check valve 229 and the inflation tube 228. The inlet check valve 232 opens when the piston 226 moves towards the external gear 221, allowing gas to enter the outer casing 227 through the inlet pipe 231. At this point, the outer casing 227 is filled with gas. When the piston 22... When the external gear 221 moves in the opposite direction, the gas in the outer shell 227 can be compressed, causing the inflation check valve 229 to open and the inlet check valve 232 to close. The gas in the outer shell 227 enters the gas storage tube 230 through the inflation tube 228. With the setting of the exhaust check valve 239, when the first airbag 209 and the second airbag 210 are full of gas, the air supply valve 234 is closed, and the outer shell 227 will continuously fill the gas storage tube 230 with gas. When the gas in the gas storage tube 230 reaches the peak storage value, the gas in the gas storage tube 230 will open the exhaust check valve 239, so that the gas that cannot be stored in the gas storage tube 230 will be discharged.

[0045] In a preferred embodiment: compression rack 1 215 and compression rack 2 216 are respectively installed on the outer walls of airbag 1 209 and airbag 2 210. Compression gear 214 meshes between compression rack 1 215 and compression rack 2 216. Compression shaft 212 is fixedly sleeved on the inner wall of compression gear 214. Rotary handle 213 is installed on the outer edge of compression shaft 212.

[0046] In the above structure, by setting up compression rack 1 215 and compression rack 216, when compression rack 1 215 and compression rack 216 move towards the center, the force of compression rack 1 215 and compression rack 216 can compress the gas in airbag 1 209 and airbag 210, so that the gas in airbag 1 209 and airbag 210 enters the gas storage pipe 230 through the gas distribution pipe 235 and the gas supply pipe 233. At this time, airbag 1 209 and airbag 210 will not inflate, and compression rack 1 215 and compression rack 216 can compress airbag 1 209 and airbag 210, so that the width of the entire device will become smaller, making the device easier to store and transport.

[0047] In a preferred embodiment: both compression rack 1 215 and compression rack 216 have limit grooves 218 on their outer edges, and both compression rack 1 215 and compression rack 216 are slidably connected to limit plates 217. The limit plates 217 are mounted on the main support 1, and the inner wall of the limit plates 217 is fitted with limit strips 219, which are slidably connected to the limit grooves 218.

[0048] In the above structure, the limiting plate 217 on the compression rack 1 215 and compression rack 216 can play a limiting role, so that the compression rack 1 215 and compression rack 216 can only slide within the limiting plate 217 and cannot move outward. Furthermore, through the cooperation of the limiting groove 218 and the limiting strip 219, the limiting groove 218 and the limiting strip 219 can limit the upward movement of the compression rack 1 215 and compression rack 216, thereby improving the stability of the movement of the compression rack 1 215 and compression rack 216.

[0049] In a preferred embodiment, a protective plate 211 is movably connected to the outer edge of the compression shaft 212. The protective plate 211 is mounted on the main support 1, and the compression gear 214 is located in the inner cavity of the protective plate 211.

[0050] In the above structure, the protective plate 211 plays a protective role, preventing the operator's fingers from entering between the compression gear 214, the first compression rack 215 and the second compression rack 216, thus improving the safety of the device during operation.

[0051] In a preferred embodiment: a protective cover 206 is fixedly sleeved on the bottom of the pump housing 205, and a plurality of round holes 207 are opened on the bottom of the protective cover 206, through which the rotating shaft 204 passes.

[0052] In the above structure, the protective cover 206 can prevent aquatic plants from entering the pumping housing 205. If a large amount of aquatic plants enter the pumping housing 205, they will come into contact with the pumping impeller 2051. In severe cases, the aquatic plants will be pulled on the pumping impeller 2051, causing blockage in the pumping housing 205.

[0053] In a preferred embodiment: a rotating disk 236 is fixedly sleeved on the outer edge of the rotating shaft 204, a cleaning brush 237 is fixedly mounted on the outer edge of the rotating disk 236, and a cutter 238 is fixedly mounted on the bottom of the cleaning brush 237.

[0054] In the above structure, the rotation of the rotating shaft 204 drives the rotating disk 236 to rotate. When the rotating disk 236 rotates, it drives the cleaning brush 237 and the cutter 238 to rotate. The cutter 238 can cut the aquatic plants in the water. When there are aquatic plants attached to the round hole 207, the cleaning brush 237 can remove the aquatic plants from the round hole 207, so that the device can successfully collect water in various water areas and improve the stability of the device.

[0055] Working principle: In use, firstly, the compression shaft 212 is rotated, which drives the compression gear 214 to rotate. The rotation of the compression gear 214 causes the compression rack 1 215 and compression rack 216 to move outwards. At this time, there is space between compression rack 1 215 and compression rack 216 and the main support 1. Then, the air supply valve 234 is opened, allowing gas from the gas storage pipe 230 to enter the airbags 1 209 and 210 through the air supply pipe 233, air supply valve 234, and air distribution pipe 235, causing the airbags 1 209 and 210 to inflate. Then... The micro-engine 201 is started, allowing the device to be placed on the water surface, causing airbags 209 and 210 to float. Airbags 209 and 210 support the micro-engine 201 and the water-pumping housing 205. The operation of the micro-engine 201 drives the rotating shaft 204, which in turn drives the water-pumping impeller 2051. As the impeller rotates, it draws water into the water-pumping housing 205, which is then discharged through the drain outlet. The rotation of the shaft 204 also drives the rotating disk 2. 36. The cleaning brush 237 and the cutter 238 rotate, and the cutter 238 breaks up the aquatic plants in the water. When aquatic plant leaves are adsorbed on the round hole 207, the cleaning brush 237 can be rotated to clean them. When the rotating shaft 204 rotates, it also drives the internal gear 220 to rotate. The rotation of the internal gear 220 drives the external gear 221 to rotate. The rotation of the external gear 221 drives the telescopic arm 225 and the piston 226 to reciprocate in the outer shell 227 through the movable support arm 224. When the piston 226 moves towards the movable support arm 224, the one-way valve 232 is opened. Gas enters the outer casing 227 through the intake pipe 231. When the piston 226 moves in the opposite direction to the movable support arm 224, the inflation check valve 229 is opened and the inlet check valve 232 is closed. The gas in the outer casing 227 is compressed into the gas storage pipe 230. The repeated movement of the piston 226 causes compressed gas to be stored in the gas storage pipe 230. When the gas storage value in the gas storage pipe 230 reaches its peak, the gas in the gas storage pipe 230 will open the exhaust check valve 239, allowing the excess gas in the gas storage pipe 230 to be discharged from the exhaust check valve 239.
