Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A composite structure for HVAC energy storage and regulation in buildings includes a housing 1, with a solar photovoltaic panel 3 mounted on the top of the housing 1. A fire-resistant mechanism 2 is located on the right side of the housing 1 to prevent fires from occurring in the energy storage battery. The fire-resistant mechanism 2 includes:

[0025] Fire extinguishing unit 21 is located on the right side of housing 1. It includes a fixed bracket 211 fixedly installed on the right side of housing 1. A dry powder tank 212 is fixedly installed inside the fixed bracket 211. An output pipe 218 is fixedly installed at the top of the dry powder tank 212. One end of the output pipe 218 penetrates into the interior of housing 1. A fixed plate 215 is fixedly installed on the right side of housing 1. An air pump 216 is fixedly installed at the top of the fixed plate 215. A connecting pipe 217 is fixedly installed at the output end of the air pump 216. One end of the connecting pipe 217 is connected to the dry powder tank 212 to pressurize the inside of the dry powder tank 212. The dry powder inside the dry powder tank 212 is sprayed out through the nozzle at one end of the output pipe 218 to prevent fire from occurring in the energy storage battery.

[0026] The reciprocating unit 22 is located on the rear side of the housing 1 and is used to realize the arc-shaped left and right rotation of the nozzle of the output pipe 218.

[0027] In this embodiment, an exhaust valve 2111 is fixedly installed on the top of the dry powder hopper 212 for venting the dry powder hopper 212. A feed knob 214 is rotatably installed inside the feed pipe on one side of the dry powder hopper 212 for adding dry powder into the dry powder hopper 212. A discharge knob 213 is rotatably installed on the discharge pipe at the bottom of the dry powder hopper 212 for discharging the dry powder inside the dry powder hopper 212.

[0028] The air pump 216, model RB-1010, is electrically connected to an external power source and is operated by a human-controlled control panel. The solenoid valve 219, model S101005170N, pressurizes the inside of the dry powder tank 212. The smoke sensor 2110 detects smoke inside the housing 1, and the solenoid valve 219 opens. The dry powder inside the dry powder tank 212 is sprayed out through the nozzle of the output pipe 218, thereby extinguishing the fire in the energy storage battery. This prevents the energy storage battery from thermal runaway due to overcharging, over-discharging, short circuit, or high temperature, which could lead to a rapid increase in battery temperature and cause a fire or explosion.

[0029] In this embodiment, a smoke sensor 2110 is fixedly installed on the top of the inner cavity of the housing 1, and a solenoid valve 219 is fixedly installed on the surface of the output pipe 218. The solenoid valve 219 is opened and closed by the smoke sensor 2110 identifying smoke.

[0030] The smoke sensor 2110 is model JTY-HS-LW1501. The smoke sensor 2110 detects smoke inside the housing 1. When smoke is detected, the solenoid valve 219 opens, and the dry powder inside the dry powder tank 212 is sprayed out through the output pipe 218 and the nozzle of the output pipe 218 to extinguish the fire in the energy storage battery.

[0031] In this embodiment, the reciprocating unit 22 includes a rotating shaft 221 rotatably mounted on the rear side of the housing 1. A fixing ring 222 is fixedly mounted on one end of the rotating shaft 221, and the nozzle end of the output pipe 218 is fixedly mounted inside the fixing ring 222. A gear 223 is fixedly mounted on the other end of the rotating shaft 221. A mounting base 224 is fixedly mounted on the rear side of the housing 1. An electric push rod 225 is fixedly mounted on one side of the mounting base 224, and a rack 226 is fixedly mounted on one end of the electric push rod 225. The rack 226 meshes with the gear 223. A protective shell 229 is fixedly mounted on the rear side of the housing 1.

[0032] The electric actuator 225, model SLEL205, is electrically connected to an external power source and is operated via a manual control panel. The actuator 225 drives the rack 226 to reciprocate, which in turn drives the gear 223 to rotate reciprocally. The gear 223, through a rotating shaft 221, drives a fixed ring 222 to rotate synchronously. The fixed ring 222 then causes the nozzle at one end of the output pipe 218 to oscillate, thereby achieving uniform fire suppression inside the housing 1.

[0033] A protective shell 229 is fixedly installed on the rear side of the housing 1, thereby protecting the electric push rod 225, rack 226 and gear 223.

[0034] In this embodiment, a T-groove 228 is provided at the bottom of the rack 226, and a limiting block 227 is fixedly installed on the rear side of the housing 1, with one end of the limiting block 227 sliding inside the T-groove 228.

[0035] One end of the limiting block 227 slides inside the T-slot 228, thereby limiting the movement of the rack 226.

[0036] In this embodiment, a heat dissipation groove 4 is provided on the front side of the housing 1, and a baffle 5 is fixedly installed on the front side of the housing 1. A heating, ventilation and air conditioning system and an energy storage battery are fixedly installed inside the housing 1.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, firstly, the air pump 216 pressurizes the inside of the dry powder tank 212. The smoke sensor 2110 detects smoke inside the housing 1. When smoke is detected, the solenoid valve 219 opens, and the dry powder inside the dry powder tank 212 is sprayed out through the nozzle of the output pipe 218 to extinguish the fire in the energy storage battery. Simultaneously, the electric push rod 225 drives the rack 226 to reciprocate, and the rack 226 drives the gear 223 to rotate reciprocally. The gear 223 drives the fixed ring 222 to rotate synchronously via the rotating shaft 221. The fixed ring 222 causes the nozzle at one end of the output pipe 218 to swing, evenly extinguishing the fire inside the housing 1.

[0039] Then, when the dry powder inside the dry powder hopper 212 expires, the user opens the exhaust valve 2111 to release the pressure inside the dry powder hopper 212, turns the discharge knob 213 to open the discharge port, and discharges the dry powder inside the dry powder hopper 212. When adding material, the discharge knob 213 is turned and installed into the discharge pipe at the bottom of the dry powder hopper 212, and the feed knob 214 is turned to open the feed port to put new dry powder into the dry powder hopper 212.
