Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting and extinguishing, and in particular to a fire handling device and a fire extinguishing method for an electric bicycle parking area. Background Art

[0002] Due to high temperatures or the effects of charging and discharging, the power batteries of electric bicycles may experience thermal runaway when parked, causing the bicycles to spontaneously combust and subsequently cause fires. Electric bicycles are often parked in rows and close together. If a fire occurs in one electric bicycle, it can easily cause fires in surrounding electric bicycles, causing the fire to spread and resulting in more serious fire accidents and losses.

[0003] Regarding fire handling of parked electric vehicles, the existing technology has the following defects:

[0004] 1. Fire extinguishing equipment is installed around the parking area. Electric vehicle fires are not easy to detect immediately, which can easily lead to serious fire accidents. At the same time, fire extinguishing equipment needs to be manually operated, which is time-consuming and labor-intensive, and very dangerous.

[0005] 2. Some places also use automatic fire extinguishing devices, but existing automatic fire extinguishing devices require a large number of sensors and control systems, and require electricity to operate the entire device, which is relatively expensive. At the same time, this type of automatic fire extinguishing device involves many devices and components, is prone to failure, has high maintenance costs, and has limited practical application scenarios;

[0006] 3. When extinguishing an electric bicycle fire, failure to take blocking measures for nearby electric bicycles can easily lead to more serious fire accidents involving electric vehicles.

[0007] Therefore, there is an urgent need for a fire disposal device and fire extinguishing method for an electric bicycle parking area to solve the above technical problems. Summary of the Invention

[0008] The purpose of the present invention is to provide a fire handling device and fire extinguishing method for electric bicycle parking areas. The device can not only effectively extinguish fires, but also isolate and protect adjacent electric bicycles to prevent the fire from further spreading. The startup and operation of the device do not require additional power supply to provide energy.

[0009] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present invention is specifically as follows: a fire handling device for an electric bicycle parking area, comprising a parking platform for electric bicycles, a fire extinguishing system and a fire spread barrier system;

[0010] The parking platform is used for parking electric bicycles, and a plurality of parking spaces are arranged on the parking platform;

[0011] The fire extinguishing system includes a gas cylinder and a fire detection tube. Fire extinguishing gas is set in the gas cylinder, and the fire extinguishing system is used to extinguish fires; the high-pressure fire extinguishing agent storage cylinder stores inert gas, such as nitrogen, carbon dioxide, and perfluorohexanone. The high-pressure fire extinguishing agent storage cylinder is equipped with a pressure gauge, which is used to monitor the pressure in the cylinder. When the pressure is lower than the working threshold, the high-pressure cylinder is replaced.

[0012] The fire spread barrier system includes a bottom body, a fire baffle and a driving device. The parking platform is arranged on the upper side of the bottom body, and the fire baffle is arranged inside the bottom body. The material of the fire baffle is a non-combustible material, such as gypsum and asbestos. When a fire occurs, the driving device is used to drive the fire baffle to move upward to isolate adjacent parking spaces and further assist in fire extinguishing.

[0013] Furthermore, a parking bracket is provided on the parking space, and the parking bracket is used to limit the parking position of the electric bicycle. The front wheel of the electric bicycle is driven into the parking bracket for parking, and its parking standards are standardized, so that the electric bicycles can be parked more neatly on the parking platform; it is convenient for the fire detection tube arranged in the middle of the parking platform to monitor and extinguish the electric bicycle that has caught fire.

[0014] The parking platform is provided with a groove that runs through all parking spaces. The groove is used to arrange the fire detection tube. The groove is set in the middle position of each parking space. The groove allows the fire detection tube to be placed on the surface of the parking platform without protruding from the surface of the parking platform, thereby avoiding wear and damage to the electric vehicle due to friction and rolling when parking.

[0015] Furthermore, the opening of the gas cylinder is connected to one end of the tee, and the other two ends of the tee are respectively connected to the fire detection pipe and the driving device. The three pipelines are interconnected and the air pressure is the same. The high-pressure fire extinguishing agent storage cylinder can be placed on the parking platform or buried underground, depending on the actual situation. A manual valve is provided at the opening of the high-pressure fire extinguishing agent storage cylinder, and each channel of the tee is provided with a manual valve. The valve can be closed to replace the high-pressure fire extinguishing agent storage cylinder.

[0016] Furthermore, a horizontal connecting rod cavity is provided in the bottom body, a limiting sliding hole connected to the connecting rod cavity is provided on the side wall of the bottom body, a plurality of spring grooves are provided on the bottom wall of the connecting rod cavity, a plurality of limiting channels corresponding to the spring grooves are provided on the top wall of the connecting rod cavity, and the upper end of the limiting channel passes through the parking platform.

[0017] Furthermore, each of the limited passages is located between two adjacent parking spaces;

[0018] The fire baffle is slidably arranged in the limiting channel.

[0019] Furthermore, the side wall of the fire baffle is provided with a placement groove, and a redundant pipeline is provided in the placement groove. The redundant pipeline is connected to the fire detection pipe. The fire baffle is installed under the parking platform and can be raised and lowered to the top of the parking platform under the action of the driving device. The fire baffle is arranged on both sides of the parked electric vehicle. When a fire occurs in the electric vehicle, it is used to block the spread of flames. The placement groove provided in the middle part of the side wall of the fire baffle corresponds to the groove on the parking platform.

[0020] Furthermore, the driving device includes a high-pressure air pipe connected to a three-way pipe at one end, a pressure switch is provided on the high-pressure air pipe, the other end of the high-pressure air pipe is connected to one end of an air cylinder, a piston is provided in the air cylinder, the side of the piston away from the high-pressure air pipe is connected to one end of a sliding rod, the other end of the sliding rod slides through the inner wall of the air cylinder and is connected to a connecting rod, the other end of the connecting rod slides through the limiting sliding hole and extends into the connecting rod cavity, and a plurality of paddles are provided on the connecting rod located in the connecting rod cavity.

[0021] Furthermore, the driving device also includes a driving spring arranged in the spring slot, and a baffle is connected to the upper end of the driving spring. The paddle is located above the spring slot, and its bottom wall abuts against the baffle, causing the driving spring to be in a compressed state. The fire baffle is placed on the upper surface of the paddle and is in sliding contact with the upper surface of the paddle. The driving spring is installed under each fire baffle, and the paddle is installed above each driving spring. The baffle installed at the upper end of the driving spring is used to increase the contact area with the fire baffle and push the fire baffle up.

[0022] Furthermore, the connecting rod located in the connecting rod cavity is perpendicular to the movement direction of the piston, which can ensure that the paddle and the connecting rod are away from the upper side of the drive spring;

[0023] The gas pressures in the fire detection tube, gas storage bottle, high-pressure gas pipe and gas cylinder are consistent and interconnected, while the pressures on both sides of the piston are the same but not connected;

[0024] The fire detection tube adopts a flexible hose with good flexibility, which is convenient for on-site arrangement of the fire detection tube according to actual terrain and needs.

[0025] The present invention also provides a method for extinguishing a fire at an electric bicycle parking area, comprising the following steps:

[0026] S1: When a fire occurs on an electric bicycle on the parking platform, the ambient temperature rises, and the fire detection tube arranged in the groove on the parking platform surface ruptures due to heat. The high-pressure fire extinguishing gas inside it sprays out from the rupture point and begins to extinguish the fire;

[0027] S2: The ejection of high-pressure gas causes the pressure inside the high-pressure gas pipe connected to the fire detection pipe to decrease. When the pressure drops to the set value, the pressure switch opens;

[0028] S3: After the pressure switch is turned on, the pressure in the cylinder close to the high-pressure gas pipe decreases, the pressure on both sides of the piston becomes unbalanced, and the piston moves toward the high-pressure gas pipe;

[0029] S4: The piston drives the sliding rod, connecting rod and paddle to move to one side at the same time. When the paddle moves to one side and leaves the top of the spring slot, the driving spring releases its elastic potential energy upward due to the loss of restraint.

[0030] S5: The driving spring releases the elastic potential energy to push the upper fire baffle upward, causing it to rise from under the parking platform. After rising, it can block both sides of the electric bicycle, forming a barrier to prevent the flame from spreading to both sides.

[0031] S6: After the fire baffle is raised, the redundant pipes arranged on both sides of the fire baffle will also rupture due to heat. At this time, the fire detection pipes will surround the electric bicycle from the bottom and both sides, and extinguish the fire on the electric bicycle from three sides at the same time.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. This device handles fires in electric vehicles by isolating the fire source and extinguishing the fire. It not only extinguishes the fire in the electric vehicle, but also provides fire protection for surrounding electric vehicles, thus improving the firefighting capability and safety in response to electric vehicle fires.

[0034] 2. The operation and startup of the device do not require the installation of an additional power supply to provide energy. It relies on the pre-stored pressure inside the device to control the activation of the fire baffle and fire extinguishing, thereby realizing the monitoring, fire isolation and fire extinguishing of non-powered electric vehicle fires. The device has sensitive monitoring and fast startup.

[0035] 3. The fire detection tube used in this device is a soft tube, which is easy to arrange and is less affected by the terrain. It can be arranged according to the actual situation of the electric vehicle parking lot. In addition, the device can be arranged not only underground but also on the inside of the wall, with a wide range of applications.

[0036] 4. This device can continue to maintain its original fire-fighting function after fire-fighting by replacing the high-pressure fire-extinguishing agent storage cylinder, fire detection tube, fire baffle and driving device. BRIEF DESCRIPTION OF THE DRAWINGS

After the pressure switch 11 is turned on, the pressure on the side of the cylinder 10 near the high-pressure gas pipe 12 decreases, and the pressure on both sides of the piston 20 is unbalanced. The piston 20 moves toward the high-pressure gas pipe 12, and the piston 20 simultaneously drives the sliding rod 21 and the connecting rod 9 At the same time as the paddle 13 moves to one side, since the paddle 13 restricts the driving spring 14, it is always in a compressed state. When the paddle 13 moves to one side, the driving spring 14 loses its restriction and releases its elastic potential energy; the driving spring 14 releases its elastic potential energy and pushes the upper fire baffle 8 to move upward, so that the fire baffle 8 rises from under the parking platform 6, which can block the two sides of the electric bicycle to prevent the flame from spreading to both sides. After the fire baffle 8 rises, the redundant pipes 7 arranged on both sides of the fire baffle 8 will also rupture due to heat. At this time, the fire detection pipes 4 surround the electric bicycle from the bottom and both sides, and extinguish the fire of the electric bicycle at the same time.

[0053] When the fire disposal device finishes working, that is, the fire extinguishing agent is sprayed, the pipeline pressure drops to normal pressure, and the fire baffle 8 rises. The high-pressure fire extinguishing agent storage cylinder 1 and the fire detection tube 4 can be replaced, and the drive spring 14 and the return paddle 13 can be re-compressed so that the drive spring 14 is in a compressed state again, and finally the fire extinguishing device can continue to be used normally.
