Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of fire detection, and in particular relates to a building fire protection facility detection device. Background Art
[0002] Smoke alarms are a type of building fire protection equipment and are crucial for preventing home fires. Their primary function is to trigger an alarm when they detect significant amounts of smoke, alerting people to take measures to prevent the occurrence or spread of a fire. The sensitivity of a smoke alarm is typically adjusted based on the location and application environment to ensure effective early warning of a fire.
[0003] Since smoke alarms are generally installed at high places, inspectors need to climb to a certain height using climbing frames when conducting inspections, and then deliver smoke to the vicinity of the smoke alarm to test whether the smoke alarm can be triggered normally. This process includes preparation, climbing, and testing. Testing at one point usually takes 3 to 5 minutes. When conducting tests at different locations, inspectors need to carry the climbing frames, especially when conducting tests between different floors. Inspectors also need to carry them up and down, which increases the burden on inspectors. Secondly, there are certain safety risks when inspectors perform height operations. Finally, smoke is generally generated by burning smoke sticks. This process involves open flames and residual particulate matter, which poses a test risk.
[0004] Therefore, a building fire protection facility detection device is provided to deal with the above situation. Summary of the Invention
[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a building fire protection facility detection device.
[0006] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows: A building fire protection facility detection device includes a power supply, a controller, a housing, a storage tank, a peristaltic pump, an ultrasonic atomizer, a micro-duct exhaust fan, a telescopic tube, and a spray nozzle; The storage tank stores the atomized liquid, and the discharge end of the storage tank is connected to the input end of the peristaltic pump; The output end of the peristaltic pump is connected to the input end of the ultrasonic atomizer; The output end of the ultrasonic atomizer is connected to the input end of the micro-duct exhaust fan; The output end of the micro-duct exhaust fan is connected to the input port of the telescopic tube; The spray nozzle is rotatably connected to the output port of the telescopic tube.
[0007] In the present invention, the atomized liquid is stored in a storage tank. A peristaltic pump is used as a power source to drive the atomized liquid into the ultrasonic atomizer at a set flow rate. The ultrasonic atomizer atomizes the atomized liquid to form smoke. A micro-duct exhaust fan generates suction to extract the smoke from the ultrasonic atomizer and transport it to a telescopic tube. The length of the telescopic tube can be adjusted by telescoping. The smoke is discharged from the spray nozzle at the output port of the telescopic tube to the vicinity of the smoke alarm. The smoke raw material is provided by the atomizing liquid. No open flame occurs during the atomization process, which further improves the safety of the test. Specifically, the atomizing liquid can be a propylene glycol-based test liquid, and a portion of glycerin can be added. The propylene glycol-based test liquid is non-toxic and harmless, and glycerin can increase the atomization stability. The amount of atomization can be controlled by the peristaltic pump, which further improves the controllability of the smoke demand. When more smoke is needed, the peristaltic pump can pump more atomized liquid. The telescopic tube can be adjusted to change its length by telescoping. The inspector can move the spray nozzle to the vicinity of the smoke alarm while standing on the ground, without having to climb up the climbing frame, which improves the safety of the inspection. When the inspection is not needed, the telescopic tube is retracted to reduce the overall size and make it easier for the inspector to carry. During the entire test process, the tester only needs to adjust the telescopic tube to the appropriate length, and no other preliminary preparation is required. The smoke generation action is implemented by the ultrasonic atomizer, which can improve the smoke generation efficiency. The time from startup to stable smoke output generally does not exceed five seconds. In addition, the amount of smoke and the smoke delivery speed can be adjusted according to actual needs, which can better adapt to different testing tasks.

Specifically, the atomizing liquid can be a propylene glycol-based test liquid and a portion of glycerin.

[0010] The technical solutions of the present invention are described in detail below in conjunction with specific embodiments and their accompanying drawings. The embodiments described herein are specific embodiments of the present invention and are used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary and should not be understood as limiting the embodiments of the present invention and the scope of protection of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims of this application and its specification, including technical solutions that adopt any obvious replacements and modifications to the embodiments described herein. Example 1
[0011] like Figure 1 、 2As shown in Figure 6, this embodiment provides a building fire protection facility detection device, including a power supply 51, a controller 52, a housing, a storage tank 3, a peristaltic pump 4, an ultrasonic atomizer 5, a micro-duct exhaust fan 6, a telescopic tube 7, and a spray nozzle 8; The storage tank 3 stores the atomized liquid, and the discharge end of the storage tank 3 is connected to the input end of the peristaltic pump 4; The output end of the peristaltic pump 4 is connected to the input end of the ultrasonic atomizer 5; The output end of the ultrasonic atomizer 5 is connected to the input end of the micro-duct exhaust fan 6; The output end of the micro-duct exhaust fan 6 is connected to the input port of the telescopic tube 7; The spray nozzle 8 is rotatably connected to the output port of the telescopic tube 7 .
[0012] In this embodiment, the atomized liquid is stored in a storage tank 3. A peristaltic pump 4 is used as a power source to drive the atomized liquid to move to an ultrasonic atomizer 5 at a set flow rate. The ultrasonic atomizer 5 atomizes the atomized liquid to form smoke. A micro-duct exhaust fan 6 generates suction to extract the smoke from the ultrasonic atomizer 5 and transport it to a telescopic tube 7. The length of the telescopic tube 7 can be adjusted by telescoping. The smoke is discharged from a spray nozzle 8 at the output port of the telescopic tube 7 to the vicinity of the smoke alarm. The smoke raw material is provided by the atomizing liquid. No open flame occurs during the atomization process, which further improves the safety of the test. Specifically, the atomizing liquid can be a propylene glycol-based test liquid, and a portion of glycerin can be added. The propylene glycol-based test liquid is non-toxic and harmless, and glycerin can increase the atomization stability. The amount of atomization can be controlled by the peristaltic pump 4, which further improves the controllability of the smoke demand. When more smoke is needed, the peristaltic pump 4 can pump more atomized liquid. The telescopic tube 7 can change its own length by telescopic adjustment. The inspector can stand on the ground and move the spray nozzle 8 to the vicinity of the smoke alarm without climbing through the climbing frame, which improves the safety of the inspection. When the inspection is not needed, the telescopic tube 7 is retracted to reduce the overall size, which is convenient for the inspector to carry. In some optional instances, the shape of the spray nozzle 8 can be selected to be L-shaped according to actual needs. The L-shaped shape changes the spray direction and the length direction of the telescopic tube 7 to a 90-degree angle. This change is very beneficial to actual operation. For example, some smoke alarms are installed on the wall. If there is no L-shaped spray nozzle 8, the inspector can also deliver the output port of the telescopic tube 7 to the vicinity of the smoke alarm, but the flow of smoke will be affected. The direction of movement will not be directly towards the smoke alarm, because the inspector is standing on the ground. If the output port of the telescopic tube 7 is to be aligned with the smoke alarm, the telescopic tube 7 needs to be horizontal. At this time, the inspector needs to maintain a more difficult posture to perform the inspection. If there is an L-shaped spray nozzle 8, it can change the direction of smoke flow. If the staff is directly below the smoke alarm, they only need to keep the telescopic tube 7 in a vertical posture. This holding posture is very comfortable. In short, the L-shaped spray nozzle 8 changes the direction of smoke outflow, making it easier for the inspector to send smoke to the smoke alarm, improving the utilization rate of smoke and reducing the difficulty of smoke delivery. The rotatable connection of the spray nozzle 8 facilitates adjustment of the circumferential direction to meet the needs of smoke delivery at different angles. In some optional embodiments, in order to facilitate operation, the housing may also be equipped with a touch screen 9 to facilitate the inspection personnel to input various control signals for opening, closing and power level adjustment; During the entire test process, the tester only needs to adjust the telescopic tube 7 to the appropriate length, and no other preliminary preparations are required. The smoke generation action is implemented by the ultrasonic atomizer 5, which can improve the smoke generation efficiency. The time from startup to stable smoke output generally does not exceed five seconds. In addition, the amount of smoke and the smoke delivery speed can be adjusted according to actual needs, which can better adapt to different detection tasks. Example 2
[0013] like Figure 3 As shown, this embodiment provides a building fire protection facility detection device. The difference from Example 1 is that the shell includes a lower shell 1 and a matching shell cover 2. The lower shell 1 is provided with a first cavity 13, a second cavity 14, and a third cavity 15. The first cavity 13 is used to install a peristaltic pump 4, the second cavity 14 is used to install an ultrasonic atomizer 5, and the third cavity 15 is used to install a micro duct exhaust fan 6.
[0014] In this embodiment, the lower shell 1 and the shell cover 2 cooperate with each other to form a relatively closed space, which continues to protect the peristaltic pump 4, ultrasonic atomizer 5, and micro-duct exhaust fan 6 therein and provides installation space. The lower shell 1 and the shell cover 2 can be separated and assembled from each other to facilitate the installation of the peristaltic pump 4, ultrasonic atomizer 5, and micro-duct exhaust fan 6, thereby improving operational convenience. The lower shell 1 and the shell cover 2 can be connected by a snap connection or by other connection methods such as bolt connection. Example 3
[0015] like Figure 3 As shown, this embodiment provides a building fire protection facility detection device, which differs from Example 2 in that a handle 11 is provided on the outer side of the lower shell 1, and the handle 11 is provided with a recess 12 adapted to the finger holding posture.
[0016] In this embodiment, the handle 11 is convenient for the inspector to grasp, and the recess 12 is adapted to the human hand, thereby improving the stability of the grasp and preventing the device from slipping out of the hand when being held. At the same time, the presence of the recess 12 is also conducive to exerting force. Example 4
[0017] like Figure 4 As shown, this embodiment provides a building fire protection facility detection device, which differs from Example 1 in that the shell cover 2 is provided with an internally threaded pipe mouth, and the storage tank 3 is provided with an externally threaded pipe mouth 32, the externally threaded pipe mouth 32 and the internally threaded pipe mouth are adapted to each other, and the storage tank 3 is installed on the shell cover 2 by a threaded connection; one end of the storage tank 3 having the externally threaded pipe mouth 32 is a discharge end, and the storage tank 3 is provided with a liquid infusion port 33 and a sealing plug 34 is inserted at the liquid infusion port 33; the outer surface of the storage tank 3 is provided with a scale ruler 31.
[0018] In this embodiment, the storage tank 3 is installed on the shell cover 2 through a threaded connection. The threaded connection is convenient for disassembly and assembly. The presence of the liquid replenishing port 33 can help the inspector to replenish the atomized liquid without removing the storage tank 3. This can avoid the residual atomized liquid from spilling when the storage tank 3 is disassembled, thereby improving the utilization rate and simplifying the liquid replenishing operation. The inspector only needs to remove the sealing plug 34 to open the liquid replenishing port 33. The scale 31 on the surface of the storage tank 3 is set to measure the volume of the internal atomized liquid, so that the inspector can clearly know how many times the atomized liquid can support the test. Example 5
[0019] like Figure 5As shown, this embodiment provides a building fire protection facility detection device, which is different from Example 1 in that the ultrasonic atomizer 5 includes an atomizing shell, an atomizing sheet 54, a heating sheet 55, a guide tube 56, and a fixing frame 53. The atomizing shell is provided with a power supply chamber, a control chamber and an atomizing chamber. The power supply 51 is located in the power supply chamber, the controller 52 is located in the control chamber, the atomizing sheet 54, the heating sheet 55, the guide tube 56, and the fixing frame 53 are located in the atomizing chamber, and the fixing frame 53 fixes the positions of the atomizing sheet 54 and the heating sheet 55. The guide tube 56 is connected to the input end of the ultrasonic atomizer 5 and guides the atomized liquid to the surface of the atomizing sheet 54 in a direction. The power supply 51 supplies power to the peristaltic pump 4, the micro-duct exhaust fan 6, the controller 52 and the atomizing sheet 54.
[0020] In this embodiment, the atomizing shell serves as a container, which not only provides a place for atomization, but also provides an installation place for the power supply 51 and the controller 52. Since the atomizing shell is in the shell and the power supply 51 is in the power supply chamber of the atomizing shell, the power supply 51 has double protection. When the inspection personnel accidentally drop the device, causing the building fire protection facility inspection device of the present invention to fall, the damage to the battery will be greatly reduced, and safety accidents such as short circuit and fire will not occur due to collision. Similarly, the controller 52 also has double protection, which improves its protection performance. In terms of atomization, the guide tube 56 transfers the atomized liquid pumped by the peristaltic pump 4 to the guide tube 56, and the guide tube 56 sends the atomized liquid to the center of the atomizing plate 54. The atomized liquid slowly spreads out and evenly covers the surface of the atomizing plate 54. After the atomizing plate 54 is started, it performs high-frequency vibration of 1.7MHz ultrasonic frequency to break the atomized liquid into droplets. The heating of the heating plate 55 can further promote the evaporation of the atomized liquid and enhance the smoke effect. Example 6
[0021] like Figure 3 As shown, this embodiment provides a building fire protection facility detection device, which differs from the first embodiment in that a magnetic attraction plate 16 with magnetic force is fixedly connected to the outer side of the shell.
[0022] In this embodiment, the function of the magnetic plate 16 is that the inspector can adsorb the building fire protection facility detection device of the present invention on a nearby metal object to free his hands. Because when inspecting in a building, there will be no special tables and chairs for inspectors to place items. Sometimes when the inspector needs to perform other operations, the detection device in his hand becomes a burden. At this time, the staff can adsorb the detection device on a nearby metal object to free his hands, so as to conveniently perform other operations.
[0023] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be covered by the claims of the present invention.
