[0035] Please refer to Figures 1-5 As shown, a technical solution of a foam spray fire extinguishing device for a shed provided by the present utility model:

[0036] A foam spray fire extinguishing device for a shed includes a plurality of partition boards 2 located in the shed 1. The plurality of partition boards 2 are evenly distributed along the length direction of the shed 1. The plurality of partition boards 2 divide the shed 1 into a plurality of partition areas. The bottom of each vertically arranged partition board 2 is fixedly connected to the bottom wall of the shed 1. The height of each partition board 2 exceeds the height of the vehicle, so that the fire source is not easily transmitted from a certain partition area to an adjacent partition area. Fire retardant layers 21 are installed on both side walls of each partition board 2. The fire retardant layers 21 are made of fire retardant materials. Specifically, the fire retardant layers 21 are made of fire retardant polyvinyl chloride. The side walls of the fire retardant layers 21 are bonded to the side walls of the partition boards 2, so that the fire source is not easily burned randomly in the shed 1, thereby reducing the damaged range of the shed 1, reducing the damage caused by the fire, and protecting property.

[0037] Inside the shed 1, a detection and fire extinguishing mechanism 4, a fire extinguishing agent storage mechanism 3 and a control box 11 are installed. The detection and fire extinguishing mechanism 4 includes a connecting pipe 41, a spray pipe 42 and a temperature sensor 44. The fire extinguishing agent storage mechanism 3 includes a water storage tank 31, a mixing tank 32, a water pump 33 and a mixing member 5. The water storage tank 31 is located on one side of the shed 1, and the bottom of the water storage tank 31 is fixedly connected to the bottom of the shed 1. Water is placed in the water storage tank 31, so that when the water supply is cut off, the water in the water storage tank 31 can still flow out, and then extinguish the fire source. The vertically arranged mixing tank 32 is located on one side of the water storage tank 31, and the bottom of the mixing tank 32 is fixedly connected to the bottom of the shed 1. The mixing member 5 includes a medicine storage tank 51, a valve 52 and a collection tank 53. The medicine storage tank 51 is located on the top wall of the mixing tank 32, and the side wall of the medicine storage tank 51 is fixedly connected to the inner side wall of the mixing tank 32. A set medicine is placed in the medicine storage tank 51. An outlet 6 is opened at the bottom of the medicine storage tank 51. The valve 52 is located at the bottom of the medicine storage tank 51. The top of the valve 52 is communicated with the medicine storage tank 51 through the outlet 6. The bottom of the valve 52 faces the collection tank 53. The collection tank 53 is located at the bottom of the valve 52, and one side of the collection tank 53 is communicated with the water storage tank 31. The other side of the collection tank 53 is communicated with the water pump 33. A foam solution formed by mixing a set medicine and water is placed in the collection tank 53. The bottom of the water pump 33 is fixedly connected to the bottom wall of the mixing tank 32, and the other end of the water pump 33 is communicated with the connecting pipe 41. One end of the connecting pipe 41 away from the mixing tank 32 is communicated with a plurality of spray pipes 42. The plurality of spray pipes 42 are evenly distributed along the length direction of the shed 1. The plurality of spray pipes 42 correspond to a plurality of partition plates 2 one by one. The nozzle of one end of each spray pipe 42 away from the connecting pipe 41 faces the bottom wall of the shed 1. There are a plurality of nozzles 43, and the plurality of nozzles 43 correspond to the plurality of spray pipes 42 one by one. Each nozzle 43 faces the bottom wall of the shed 1. The temperature sensor 44 is selected to adopt an 85°C linear temperature detection line. The temperature sensor 44 is located on the top wall of the shed 1. The temperature sensor 44 is connected to the top wall of the shed 1. The temperature sensor 44 is connected to the control box 11. The control box 11 is located on one side of the water storage tank 31, and the control box 11 is fixedly connected to the shed 1.

[0038] The temperature sensor 44 detects the temperature inside the shed 1. When a fire breaks out at a certain place inside the shed 1, the temperature above that place exceeds the set temperature of the temperature sensor 44. The corresponding control box 11 controls the water pump 33 to start. At this time, the valve 52 is opened, and the water in the water storage tank 31 and the set medicine in the medicine storage tank 51 are transmitted into the collection tank 53. After passing through the water pump 33, and then through the connecting pipe 41, a plurality of spray pipes 42 and a plurality of nozzles 43, the foam solution sprayed by the nozzle 43 above the corresponding place contacts the fire source, thus extinguishing the fire.

[0039] Inside the shed 1, a thermal imaging camera 71, a smoke sensor 72 and a buzzer 73 are installed. The thermal imaging camera 71 is fixedly connected to the top wall of the shed 1. The thermal imaging camera 71 detects the shed 1. When the thermal imaging camera 71 detects an open fire, the thermal imaging camera 71 triggers an alarm signal and transmits the alarm signal to a set position, such as a cloud server management platform and a mobile phone WeChat mini-program, so as to remind the staff to start the water pump 33 to extinguish the fire. There are multiple smoke sensors 72, and the multiple smoke sensors 72 are evenly distributed along the length direction of the shed 1. Each smoke sensor 72 corresponds to each partition board 2 one by one. Each smoke sensor 72 is a wireless smoke sensor 72. When the smoke sensor 72 detects that the smoke in the shed 1 reaches a certain concentration, the smoke sensor 72 controls the buzzer 73 to alarm, and makes the cloud server management platform and the mobile phone WeChat mini-program send out alarm signals, and is convenient to start the water pump 33 to extinguish the fire.

[0040] The working principle of the present utility model is as follows:

[0041] When the foam spray fire extinguishing device for a shed in this embodiment is in use, the multiple partition boards 2 and the flame retardant layer 21 divide the shed 1 into multiple partition areas, so that when a fire occurs, the fire source is not easy to continue burning, thereby reducing the loss caused by the fire source to the shed 1 and protecting property. When a fire occurs in the shed 1, the thermal imaging camera 71 is started and the picture is transmitted to a set position. At the same time, the smoke sensor 72 contacts the smoke, so that the buzzer 73 gives an alarm. In addition, the temperature sensor 44 detects that the temperature in the shed 1 exceeds the set temperature, and the control box 11 issues a control signal. At this time, the valve 52 is opened, and the set medicine in the medicine storage tank 51 contacts and mixes with the water in the water storage tank 31 to form a foam solution. Through the water pump 33, the foam solution passes through the connecting pipe 41, the spray pipe 42 and the nozzle 43, and the nozzle 43 sprays out the foam solution to contact the fire source and extinguish the fire.

[0042] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
