Description

Technical Field

[0001] This utility model relates to the field of automatic fire extinguishing technology, and in particular to a fire extinguishing device for electric bicycle shed fires. Background Technology

[0002] The increasing demand for centralized parking and charging of electric bicycles in residential areas and public places has led to a significant increase in the risk of fires in bicycle sheds. Due to battery failure, aging electrical wiring, or overloaded charging equipment, electric bicycles are prone to fires during charging, which spread rapidly and often produce toxic fumes. Traditional fire extinguishing devices also have the following shortcomings in use: Firstly, traditional fire extinguishing devices rely on a single method of fire detection, which is often limited to manual inspections or single-point sensors. This makes them susceptible to environmental interference and difficult to identify initial fires in a timely and accurate manner. Secondly, currently, many carports are equipped with fixed sprinkler systems, whose nozzle positions and spray directions cannot be changed; when the fire source is located at the edge of the nozzle coverage area or is blocked by the carport structure, the fire extinguishing effect will be greatly reduced.

[0003] To address the aforementioned problems, this utility model document proposes a fire extinguishing device for electric bicycle shed fires. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as the limited detection methods of traditional fire extinguishing devices, which make it difficult to identify fires in a timely manner, and the inconvenience of adjusting the nozzles of fixed sprinkler systems in carports, resulting in insufficient fire extinguishing effect. Therefore, this utility model proposes a fire extinguishing device for electric bicycle carport fires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fire extinguishing device for electric bicycle shed fires, comprising: The main body of the carport consists of a support frame and multiple roof covers, with the multiple roof covers fixedly installed on the inclined surface at the top of the support frame; The fire extinguishing assembly includes a control box and two water supply pipes. The control box is equipped with a controller and a pump set. Multiple spray heads are fixedly installed on the outer walls of the two water supply pipes. The multiple spray heads are used to spray fire extinguishing spray towards the fire source below. And two sets of adjustment components, which are used to adjust the horizontal position and rotation state of the two water supply pipes to adjust the position and angle of multiple spray heads; When the flame detector detects a fire, the controller activates the adjustment component to direct the spray head towards the fire source, while the pump unit delivers extinguishing agent through the water pipe to the spray head for fire suppression.

[0006] In one possible design, the adjustment assembly includes multiple first fixed brackets fixedly installed at the bottom of the support frame beam. All first fixed brackets are located on the same side inside the support frame. Each of the multiple first fixed brackets has a first slider slidably connected inside it. One end of an adjacent water pipe rotatably passes through the multiple first sliders located on the same side. A protrusion is fixedly connected to the bottom of each of the multiple first sliders. A screw is rotatably installed on the bottom of each of the multiple first fixed brackets. A first servo motor is fixedly installed on one side of each of the multiple first fixed brackets. The output shafts of the multiple first servo motors are respectively fixedly connected to one end of an adjacent screw. The multiple screws located on the same side are used to drive the horizontal movement of the corresponding water pipe.

[0007] In one possible design, the adjustment assembly further includes a third fixing bracket disposed at one end of the water supply pipe. The third fixing bracket is fixedly installed at the bottom of the corresponding crossbeam of the support frame, and the third fixing bracket is located at the end of the support frame away from the control box. A third slider is slidably connected inside the third fixing bracket. The other end of the water supply pipe rotatably passes through the corresponding third slider. A second servo motor is fixedly installed on one side of the third slider. The output shaft of the second servo motor is fixedly connected to one end of the adjacent water supply pipe to drive the water supply pipe to rotate.

[0008] In one possible design, the fire extinguishing assembly further includes a fixed pipe fixedly installed on one side of the support frame. A connecting pipe is fixedly connected to the outer wall of the fixed pipe, and the other end of the connecting pipe is fixedly connected to the outlet of the pump unit inside the control box. Two second fixed frames are provided at the end of the support frame near the control box. Both second fixed frames are fixedly connected to the bottom of the corresponding crossbeam of the support frame. A second slider is slidably connected inside each of the two second fixed frames. A rotating water connector is fixedly passed through the inside of each of the two second sliders. The rotating part of the two rotating water connectors is fixedly connected to one end of an adjacent water supply pipe. Two flexible hoses are fixedly connected to the outer wall of the fixed pipe. The other ends of the two flexible hoses are respectively fixedly connected to the fixed part of the corresponding rotating water connector to deliver the fire extinguishing agent.

[0009] In one possible design, a water-based fire extinguishing agent tank is fixedly mounted on one side of the control box via a bracket. The interior of the water-based fire extinguishing agent tank is filled with water-based fire extinguishing agent, and the water-based fire extinguishing agent tank is connected to the water inlet of the pump unit inside the control box. The outer wall of the water-based fire extinguishing agent tank is provided with an interface for connecting to an outdoor fire hydrant.

[0010] In one possible design, multiple fixing rods are fixedly installed at the bottom of the support frame, the multiple fixing rods are spaced apart, and mounting brackets are fixedly installed on the outer walls of the multiple fixing rods. Flame detectors are fixedly installed at both ends of the multiple mounting brackets, and the flame detectors are used to detect fire inside the main body of the carport.

[0011] In one possible design, a display screen is fixedly installed on one side of the control box, and an audible and visual alarm device and a camera are fixedly installed on the top of the control box. The camera is used to observe the fire situation inside the main body of the carport, and the audible and visual alarm device is used to issue an alarm.

[0012] In one possible design, a solenoid valve is provided at the connection interface of multiple spray heads, and the controller controls the corresponding solenoid valve to open according to the location of the fire, so that the spray head sprays out the extinguishing agent.

[0013] In this application, when a fire occurs in the electric bicycle shed, the flame detector and the corresponding heat-sensing cable installed at the bottom of the support frame will monitor the fire and ambient temperature in the shed in real time. If an abnormal temperature rise is detected, reaching the preset fire alarm threshold, or abnormal light radiation is detected, it will immediately transmit the signal to the controller in the control box. At the same time, the camera on the top of the control box will continuously monitor the shed with video. When the camera detects fire signs such as flames or smoke, it will also transmit the signal to the controller. Upon receiving a fire signal, the controller first activates the audible and visual alarm device on top of the control box to alert personnel inside and around the shed to the fire. Simultaneously, the controller activates the first and second servo motors to adjust the position and angle of the water supply pipe. At this time, the output shafts of multiple first servo motors rotate synchronously, driving the corresponding screws to rotate. The rotation of the screws causes the first slider to slide within the first fixed frame, thereby pushing the water supply pipe to move horizontally to adjust the horizontal position of the spray head. At the same time, the output shaft of the second servo motor rotates, which can drive the water supply pipe to rotate around its axis as needed, thereby adjusting the spray angle of the spray head so that the spray head can accurately aim at the fire source. While adjusting the position and angle of the water supply pipe, the controller starts the pump unit in the control box. The pump unit draws water-based fire extinguishing agent from the water-based fire extinguishing agent tank, which is connected to an outdoor fire hydrant. When the fire extinguishing agent in the tank is insufficient, water can be replenished through the outdoor fire hydrant. After pressurizing the fire extinguishing agent, the pump unit delivers it to the fixed pipe through the connecting pipe, and then transmits it to the rotary water connector through the hose. The rotating part of the rotary water connector is fixedly connected to the water supply pipe and can rotate flexibly with the movement and rotation of the water supply pipe to ensure that the fire extinguishing agent is delivered smoothly to the water supply pipe. At the same time, solenoid valves are installed at the connection interfaces of multiple spray heads. When the fire location is detected according to the temperature, the controller can control the solenoid valve at the corresponding position to open, so that the spray head at the corresponding position can complete the spraying of the fire extinguishing agent, so that the fire extinguishing agent can be evenly sprayed to the fire source below to complete the spray extinguishing of the fire source. During firefighting, the controller continuously receives signals from flame detectors and cameras to monitor the fire situation in real time. If the fire is large, the position and angle of the spray heads can be further adjusted by adjusting the components. At the same time, the solenoid valve can be controlled to open the remaining spray heads to ensure that the extinguishing agent can fully cover the fire source. When the fire is extinguished, the controller controls the pump group to stop working, the spray heads to stop spraying, and the audible and visual alarm devices to stop alarming. Meanwhile, staff can view the real-time situation inside the carport through the display screen of the control box, and inspect and maintain the fire extinguishing equipment to ensure that it can work normally in the event of the next fire.

[0014] Beneficial effects: In this utility model, the fire extinguishing device for electric bicycle sheds uses flame detectors spaced at the bottom of the support frame to collect temperature data inside the shed in real time. Combined with video monitoring from the top camera, a dual monitoring mechanism of temperature signal and image recognition is formed. When the flame detector detects an abnormal temperature rise to a preset threshold, or the camera identifies fire signs such as flames or smoke, it can simultaneously transmit a signal to the controller in the control box to ensure accurate early judgment of the fire. The controller immediately activates the audible and visual alarm device to buy time for personnel evacuation and external rescue, avoiding response delays caused by misjudgment or missed judgment due to a single detection method. In this utility model, the fire extinguishing device for an electric bicycle shed fire has two sets of adjustment components working in tandem. The first servo motor drives the screw to rotate, causing the first slider to slide within the fixed frame, thus achieving precise adjustment of the horizontal position of the water supply pipe. The second servo motor directly drives the water supply pipe to rotate around the axis, flexibly changing the spray angle of the spray head. The combination of the two components allows the spray head to quickly aim at the fire source, solving the problem of blind spots in the coverage of traditional fixed sprinkler devices. At the same time, the water supply pipe is connected to the hose through a rotating water connector, ensuring the continuity of the extinguishing agent delivery during the adjustment process, avoiding the impact of pipe twisting or pulling on the water supply, and improving the mobility and accuracy of fire extinguishing operations. In this utility model, the fire extinguishing device for electric bicycle shed fires has a control box with a built-in pump unit connected to a water-based fire extinguishing agent tank. The tank stores a fixed amount of fire extinguishing agent and can also be connected to an outdoor fire hydrant through an external interface, forming a dual water source guarantee of built-in reserve and external replenishment. When the tank is low on water, the fire hydrant water source can be directly pumped out to avoid the fire reigniting due to water interruption during fire extinguishing. The delivery pipeline, consisting of connecting pipes, fixed pipes, and flexible hoses, is reasonably laid out. Combined with the flexible rotation characteristics of the rotary water connector, it ensures that the fire extinguishing agent is stably delivered to each spray head under the action of the high-pressure pump unit, meeting the needs of long-term, high-intensity fire extinguishing. In this invention, the device achieves early and accurate judgment of fire conditions through dual monitoring of temperature and image. By using a servo motor to drive the water pipe to move and rotate accordingly, the spray head can be quickly and accurately aimed at the fire source. At the same time, the fire extinguishing agent supply system has dual protection of built-in storage and connection to external fire hydrants. Combined with the setting of the rotating water connector, it can ensure the continuous and stable delivery of fire extinguishing agent, which can effectively improve fire extinguishing efficiency and system reliability.

[0022] This application can be used in the field of automatic fire extinguishing technology, or in other fields applicable to this application.

[0023] In another embodiment: Reference Figure 1 , 4 6. A fire extinguishing device for electric bicycle shed fires, which is applied to the field of automatic fire extinguishing technology; In this embodiment, the water-based fire extinguishing agent tank 5 is fixedly installed on one side of the control box 4 by a bracket. It is filled with water-based fire extinguishing agent and is connected to the water inlet of the pump group inside the control box 4 to provide a source of fire extinguishing agent. The outer wall of the water-based fire extinguishing agent tank 5 is provided with an interface for connecting to an outdoor fire hydrant. When needed, the connection to the outdoor fire hydrant can be completed through this interface to replenish the fire extinguishing agent.

[0024] In this embodiment, a plurality of spaced-apart fixed rods 23 are fixedly installed at the bottom of the support frame 2. Mounting brackets 24 are fixedly installed on the outer wall of the fixed rods 23. Flame detectors 25 are fixedly installed at both ends of the mounting brackets 24. The flame detectors 25 are of the Zhong'an Tan S600 type and are used to detect the temperature of the fire inside the carport body 1. At the same time, in this application, a heat-sensing cable can also be selected for auxiliary fire monitoring. The heat-sensing cable can be of the JTW-LD-WT303C type. When the heat-sensing cable and the flame detectors 25 detect an abnormal increase in temperature or the appearance of flames, they can transmit signals to the control box 4.

[0025] In this embodiment, a display screen is fixedly installed on one side of the control box 4, which can display the working status of the device, temperature information, etc.; an audible and visual alarm device and a camera 6 are fixedly installed on the top of the control box 4. The camera 6 is used to observe the fire situation inside the main body 1 of the carport. When a fire is detected, the audible and visual alarm device will sound an alarm to remind the surrounding personnel to pay attention.

[0026] Meanwhile, each of the multiple spray heads 8 is equipped with a solenoid valve at its connection interface. When the fire location is detected based on the temperature, the controller can control the solenoid valve at the corresponding location to open, thereby enabling the spray head 8 at the corresponding location to spray the extinguishing agent, so that the extinguishing agent can be evenly sprayed to the fire source below, thus completing the spray extinguishing of the fire source. However, as is well known to those skilled in the art, the working principles and wiring methods of the control box 4, camera 6, first servo motor 13, second servo motor 22, flame detector 25, and corresponding solenoid valves and temperature sensing cables are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0027] The working principle and usage process of this technical solution are as follows: When a fire occurs in the electric bicycle shed, the flame detector 25 and the corresponding temperature sensing cable installed at the bottom of the support frame 2 will detect the fire and ambient temperature in the shed in real time. If an abnormal temperature rise is detected, reaching the preset fire alarm threshold or abnormal light radiation is detected, it will immediately transmit the signal to the controller in the control box 4. At the same time, the camera 6 on the top of the control box 4 will continuously monitor the shed with video. When the camera 6 detects fire signs such as flames or smoke, it will also transmit the signal to the controller. Upon receiving a fire signal, the controller first activates the audible and visual alarm device on top of the control box 4 to alert personnel inside and around the shed to the fire. Simultaneously, the controller activates the first servo motor 13 and the second servo motor 22 to adjust the position and angle of the water supply pipe 7. At this time, the output shafts of multiple first servo motors 13 rotate synchronously, driving the corresponding screws 12 to rotate. The rotation of the screws 12 causes the first slider 10 to slide within the first fixed frame 9, thereby pushing the water supply pipe 7 to move horizontally to adjust the horizontal position of the spray head 8. At the same time, the output shaft of the second servo motor 22 rotates, which can drive the water supply pipe 7 to rotate around its axis as needed, thereby adjusting the spray angle of the spray head 8 so that the spray head 8 can accurately aim at the fire source. While adjusting the position and angle of the water supply pipe 7, the controller starts the pump unit in the control box 4. The pump unit draws water-based fire extinguishing agent from the water-based fire extinguishing agent tank 5, which is connected to an outdoor fire hydrant. When the fire extinguishing agent in the tank is insufficient, water can be replenished through the outdoor fire hydrant. After pressurizing the fire extinguishing agent, the pump unit delivers it to the fixed pipe 15 through the connecting pipe 14, and then to the rotating water connector 19 through the hose 16. The rotating part of the rotating water connector 19 is fixedly connected to the water supply pipe 7 and can rotate flexibly with the movement and rotation of the water supply pipe 7 to ensure that the fire extinguishing agent is delivered smoothly to the water supply pipe 7. At the same time, solenoid valves are installed at the connection interfaces of multiple spray heads 8. When the fire location is detected according to the temperature, the controller can control the solenoid valve at the corresponding position to open, so that the spray head 8 at the corresponding position can complete the spraying of the fire extinguishing agent, so that the fire extinguishing agent can be evenly sprayed to the fire source below to complete the spray fire extinguishing. During the firefighting process, the controller continuously receives signals from the flame detector 25 and the camera 6 to monitor the fire situation in real time. If the fire is large, the position and angle of the spray head 8 can be further adjusted by adjusting the components. At the same time, the solenoid valve can be controlled to open the remaining spray heads 8 to ensure that the extinguishing agent can fully cover the fire source. When the fire is extinguished, the controller controls the pump group to stop working, the spray head 8 stops spraying, and the audible and visual alarm device stops alarming. At the same time, the staff can view the real-time situation in the carport through the display screen of the control box 4 according to the on-site situation, and check and maintain the fire extinguishing device to ensure that it can work normally in the event of the next fire.

[0028] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
