Description

Technical Field

[0001] The utility model relates to the technical field of laboratory fire protection, in particular to a patrol type smoke detection device and a patrol type smoke detection fire protection device. Background Art

[0002] During the development of lithium batteries, lithium batteries need to be placed in a special laboratory for charging and discharging experiments to test the relevant performance indicators of lithium batteries. During the charging and discharging experiments of lithium batteries, overheating and spontaneous combustion may occur. In order to avoid fires caused by spontaneous combustion of lithium batteries, smoke sensors are often installed on the top of the lithium battery laboratory. At the same time, corresponding fire extinguishing equipment is also equipped inside the laboratory. When the smoke sensor detects smoke in the laboratory, it will immediately feed back the information to the controller, and then the controller will operate the fire extinguishing equipment to extinguish the fire.

[0003] In order to detect and alarm smoke and automatically start fire-fighting equipment, existing lithium battery testing laboratories often install smoke sensors directly at the center of the laboratory ceiling, and then connect the smoke sensors to the controller wires in the laboratory. Since the smoke sensors are fixed in position, and there are generally multiple lithium batteries in the lithium battery laboratory for charge and discharge experiments, when a lithium battery far away from the smoke sensor spontaneously ignites, the smoke sensor cannot detect the presence of smoke in the first place, resulting in a lag in the operation of the fire-fighting equipment, and it is impossible to extinguish the fire in the first place when the lithium battery spontaneously ignites.

[0004] In addition, existing smoke sensors often have a filter on the inner side of the smoke inlet of their outer cover to prevent impurities in the air from entering the interior and interfering with the sensor's detection. However, due to the presence of the filter, dust in the air will adhere to the filter over a long period of time. As the amount of attached dust increases, smoke cannot quickly and effectively enter the interior of the sensor, causing the sensitivity of the smoke sensor to decrease. In order to ensure the smoke sensor's sensitivity to smoke detection, operators are often required to regularly use a lifting frame to lift themselves to the upper end of the laboratory, and then manually clean them. The entire manual cleaning process of the smoke sensor is not only time-consuming and labor-intensive, but also poses certain safety hazards.

[0005] Therefore, in order to address the shortcomings of existing lithium battery laboratories that use fixedly installed smoke sensors to monitor the spontaneous combustion of lithium batteries in real time and require manual dust removal and cleaning of the smoke sensors on a regular basis, the present application proposes a smoke detection fire-fighting equipment based on a lithium battery testing laboratory that can effectively solve the above technical problems.

[0038] Example 1

[0039] Figure 1 The invention relates to a patrol type smoke detection device used in a lithium battery testing laboratory, which is composed of a track seat 4, a patrol component 6, a smoke sensor 100 and a controller 300.

[0040] The track stand is mounted and fixed on the ceiling of the lithium battery testing laboratory.

[0041] The track seat is in the shape of a disc, and a closed circular track 5 is arranged around the bottom edge of the track seat. Figure 2 ).

[0042] Roller grooves recessed inwards are arranged on both inner and outer sides of the annular track.

[0043] Figure 4 In the embodiment, the patrol assembly is composed of a carrier plate 601, a travel motor 603 and a pair of travel wheels 602, wherein the travel wheels are composed of a driving wheel and a driven wheel. The pair of travel wheels are arranged on the upper end surface of the carrier plate, wherein the driving wheel is connected to the travel motor, and the smoke sensor is fixedly mounted on the lower end surface of the carrier plate ( Figure 3 ).

[0044] During assembly, the driving wheel and the driven wheel are respectively embedded in the roller grooves on the inner and outer sides of the circular track. During operation, the travel motor drives the driving wheel to drive the carrier to patrol along the circular track, and the controller controls the patrol assembly to patrol along the circular track.

[0045] The upper end of the circumferential surface of the track seat is provided with a circle of mounting plate 401 which is turned outwards, and a plurality of mounting holes are opened on the mounting plate and evenly distributed on a circle of the mounting plate. During installation, the entire track seat is mounted on the ceiling of the lithium battery laboratory through connectors such as expansion bolts.

[0046] A camera 8 is also mounted on the carrier board 601, and the lens of the camera 8 is arranged downward ( Figure 4 ). The camera moves in a circular motion along with the patrol component on the circular track, and the internal images of the lithium battery laboratory can be captured through the camera during the inspection process.

[0047] In this embodiment, there are two installation methods for the controller 300. The first installation method is to directly install it in the inner cavity of the track seat. The second installation method is to add a control display cabinet in other suitable places and directly set the controller 300 in the control display cabinet. The controller can be connected to the smoke sensor through remote control technology.

[0048] exist Figure 5 In the present invention, the storage module and the controller are both arranged inside the control display cabinet. The storage module is connected to the camera through remote control technology, and the controller is also connected to the smoke sensor and the walking motor through remote control technology, and the controller controls the operation of the entire patrol type smoke detection device.

[0049] The control display cabinet can also be equipped with a display screen and an operation panel. The operation panel can control the speed and frequency of the patrol component moving on the circular track according to the inspection requirements. The inspection data can be transmitted back to the control display cabinet, and then the display screen can be used to view the values ​​of each area in real time. At the same time, the display screen can also facilitate subsequent operators to retrieve the images captured by the camera in the lithium battery test laboratory.

[0050] exist Figure 1 In the embodiment, the patrol type smoke detection device is also equipped with a high-pressure purge system for cleaning the dust on the surface of the smoke sensor. The high-pressure purge system is composed of a compressed gas tank 7, an air pipe 701, an electromagnetic valve 702 and a nozzle 703. The compressed gas tank is arranged in the inner cavity of the track seat, one end of the air pipe is connected to the compressed gas tank, and the other end of the air pipe extends outward from the inner cavity of the track seat and is connected to the nozzle. The nozzle is arranged toward the smoke sensor moving along the circular track, and the nozzle is controlled by the electromagnetic valve to start or stop the jet.

[0051] exist Figure 2 In the embodiment, the inner cavity of the track seat is provided with a disassembly opening 403, which is sealed by a sealing plate 404. The compressed gas tank is fixedly arranged on the sealing plate, and the area of ​​the disassembly opening is adapted to the size of the compressed gas tank. When the compressed gas tank is used up, the sealing plate can be removed from the disassembly opening to complete the replacement of the old compressed gas tank with the new one.

[0052] In order to spray high-pressure gas onto the smoke sensor surface only when it moves to the position of the nozzle, a proximity switch 704 is provided in the inner cavity of the track seat in this embodiment. The proximity switch and the nozzle are respectively located on the inner and outer sides of the same radial line of the circular track, and the proximity switch and the solenoid valve are both electrically connected to the controller ( Figure 6 ), and a sensing block 604 for triggering a proximity switch is also provided at the inner end of the carrier board.

[0053] The high-pressure purge system of this embodiment effectively ensures the detection sensitivity of the smoke sensor, and does not require operators to climb high to perform manual cleaning.

[0054] Working principle:

[0055] The carrier board driven by the travel motor drives the smoke sensor along the circular track to perform periodic inspections within the installation range of the circular track in the lithium battery testing laboratory. Once the lithium battery spontaneous combustion or other combustion phenomena are found, a signal is sent out to control the corresponding alarm device through the controller to alarm, or control the fire-fighting equipment to extinguish the fire.

[0056] If necessary, the diameter of the circular track can be designed according to the area of ​​the lithium battery testing laboratory. If the area of ​​the lithium battery laboratory is large, several sets of circular tracks and smoke sensors can be installed at the same time. Multiple smoke sensors can be connected to the same controller, and the same controller can control the operation of multiple sets of patrol smoke detection devices.

[0057] During the actual operation of the entire device, the surface of the smoke sensor should be cleaned of dust every few days. When the surface of the smoke sensor needs to be cleaned, the proximity switch is first turned on by the controller, and then when the patrol component moves to the radial line between the proximity switch and the nozzle, the induction block installed on the patrol component triggers the proximity switch, and the proximity switch immediately controls the travel motor to stop running through the controller, and at the same time opens the solenoid valve to allow the high-pressure gas stored in the compressed gas tank to spray from the nozzle to the smoke sensor, thereby automatically cleaning the dust accumulated on the surface of the smoke sensor.

[0058] This embodiment also has a camera on the patrol component, which is used to capture the images inside the lithium battery laboratory in real time during the inspection process. The display control cabinet can not only collect inspection data in real time, but also allow staff to retrieve image data inside the laboratory, etc. It has various functions and excellent use effects.

The fire fighting equipment is connected to the smoke sensor through a controller, and the signal sent by the smoke sensor starts the fire fighting equipment through the controller to extinguish the fire.

[0061] Fire fighting equipment can be dry powder fire extinguisher, carbon dioxide fire extinguisher or water sprinkler equipment. Dry powder fire extinguisher, carbon dioxide fire extinguisher or water sprinkler equipment can be used alone or in combination.
