Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and in particular to an audible and visual alarm and a fire self-inspection alarm device. Background Technology

[0002] With economic development and the increasing trend of urbanization, the large-scale concentration of population, buildings, property, and commerce exacerbates the damage caused by fires. If fires can be detected and extinguished in their early stages, the losses can be greatly reduced. A fire alarm system with audible and visual alarms and a self-inspection alarm device can enable timely detection of fires in their early stages.

[0003] Currently, the core components of existing fire self-inspection alarm devices, such as smoke detectors and audible and visual alarms, are exposed to the elements for extended periods without effective protective structures. This makes them susceptible to decreased sensitivity or even failure due to dust accumulation, external impacts, or harsh environmental corrosion, severely impacting the reliable operation of the equipment. Furthermore, while existing fire self-inspection alarm devices have an inspection function, the inspected areas require regular spraying to maintain humidity and prevent excessive dryness that could lead to fire hazards. This necessitates manual, periodic spraying by staff, separate from the existing fire self-inspection alarm device operation, resulting in wasted manpower and time.

[0004] Therefore, this invention proposes an audible and visual alarm and a fire self-inspection alarm device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an audible and visual alarm and a fire self-inspection alarm device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an audible and visual alarm and a fire self-inspection alarm device, comprising an inspection vehicle and a guide rail, wherein the guide rail is fixedly installed around the inner wall of the inspection vehicle.

[0007] The inspection vehicle is equipped with a protective shell on the top, a control box is fixedly installed at the center of the front of the inspection vehicle, a servo motor is fixedly installed on the top of the control box, and casters are fixedly installed around the bottom of the inspection vehicle.

[0008] A lead screw is rotatably sleeved at the center of one surface of the guide rail. A slider is threaded onto the surface of the lead screw. A support plate is fixedly clamped to one side of the slider. A light alarm and a horn are fixedly installed on the top of the support plate. Clamping plates are fixedly clamped around the outer surface of the support plate. A plug rod is fixedly installed at the bottom of the clamping plates.

[0009] A water tank is fixedly installed on the bottom inside the inspection vehicle, and a sealing plate is fixedly installed on the top of the water tank. The sealing plate has insertion holes on its surface. An installation plate is fixedly installed on the bottom surface of the inspection vehicle, and a water outlet pipe is fixedly installed on the bottom of the installation plate. A nozzle is fixedly connected to the bottom surface of the water outlet pipe.

[0010] Preferably, smoke detectors are fixedly installed on both sides of the top surface of the support plate, guide rails are fixedly installed on both sides of the front surface of the smoke detectors, baffles are slidably installed on the surface of guide rails, and grilles are fixedly installed on both sides of the outer surface of the inspection vehicle.

[0011] Preferably, the slider moves up and down on the surface of the lead screw via a servo motor, and simultaneously drives the support plate to move up and down, so that the top of the smoke sensor contacts the bottom of the baffle, and the surface of the smoke sensor is parallel and correspondingly connected to the surface of the grille.

[0012] Preferably, the light alarm and horn are raised and lowered synchronously inside the inspection vehicle via a support plate, with the top of the light alarm and horn vertically aligned with the bottom of the protective shell, so that the light alarm and horn are locked in place inside the protective shell.

[0013] Preferably, a water inlet pipe is fixedly installed on one side of the surface of the inspection vehicle, and one side of the surface of the water inlet pipe is connected to the inside of the water tank.

[0014] Preferably, the support plate is raised and lowered inside the inspection vehicle, which drives the plug rod to rise and fall. The bottom of the plug rod is perpendicular to the plug hole and passes through the plug hole.

[0015] Preferably, a guide rail three is fixedly installed on the inner wall of the water tank, and a positioning plate is slidably installed on both sides of the surface of the guide rail three. A baffle two is fixedly connected to one side of the surface of the positioning plate, and a pressing block is fixedly installed at the bottom of the baffle two. A reset spring is fixedly installed at the bottom of the pressing block.

[0016] Preferably, one side of the extrusion block surface is connected to the inside of the water outlet pipe via a mounting plate. The insertion rod passes through the insertion hole and contacts the extrusion block surface, pressing it. The positioning plate drives the baffle two to slide and adjust on the surface of the guide rail three, so that the inside of the water tank and the inside of the water outlet pipe are connected. When the insertion rod passes through the insertion hole of the sealing plate and presses the extrusion block in the water tank, it can push the positioning plate and the baffle two to slide along the guide rail three, so that the water tank and the water outlet pipe are connected, and then emergency spraying operation can be realized through the nozzle. At the same time, the baffle one on the surface of the guide rail two can slide and adjust, which can protect the smoke sensor according to actual needs and prevent it from failing due to dust accumulation or external impact. The water inlet pipe ensures the continuous water supply capacity of the water tank, improves the efficiency of fire early warning and response, and reduces the risk of fire hazards remaining.

[0017] Preferably, a positioning rod is fixedly installed inside the return spring, and the plug-in rod presses against the pressing block and engages with the surface of the positioning rod.

[0018] An audible and visual alarm device, comprising any one of the above-mentioned fire self-inspection alarm devices.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The patrol vehicle utilizes casters at its bottom to enable mobile patrols across the entire area, adapting to various fire inspection needs. A servo motor drives a lead screw to rotate, raising and lowering the slider and support plate. This ensures the smoke detector aligns parallel to the grilles on both sides of the vehicle, improving smoke detection sensitivity and coverage. It also allows the light alarm and horn to be raised and secured within a protective housing, protecting them from external environmental damage during non-operational periods. Simultaneously, the support plate's raising and lowering motion moves the connecting rod. When the connecting rod penetrates the sealing plate's insertion hole and presses against the compression block inside the water tank, it pushes the positioning plate and baffle two along guide rail three, connecting the water tank to the outlet pipe. This enables emergency spraying via the nozzles. Meanwhile, baffle one on guide rail two is adjustable to protect the smoke detector from dust accumulation or external impact, preventing malfunction. The inlet pipe ensures a continuous water supply to the tank, improving the efficiency of fire warning and response, and reducing the risk of lingering fire hazards. Attached Figure Description

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 A sound and light alarm and a fire self-inspection alarm device, including an inspection vehicle 100 and a guide rail 200, wherein the guide rail 200 is fixedly installed around the inner wall of the inspection vehicle 100.

[0031] The inspection vehicle 100 is equipped with a protective shell 103 on its top, a control box 101 is fixedly installed at the center of the front end of the inspection vehicle 100, a servo motor 102 is fixedly installed on the top of the control box 101, and casters 104 are fixedly installed around the bottom of the inspection vehicle 100.

[0032] In use, the device uses the inspection vehicle 100 as a mobile carrier. With the help of the casters 104 around its bottom, it can move flexibly throughout the entire area to meet the fire inspection needs in different scenarios. The guide rails 200 fixedly installed on the inner wall of the inspection vehicle 100 provide structural support for the lifting and adjustment of subsequent components. The servo motor 102 on the top of the control box 101 provides the power source for the lifting and lowering of the components. The protective shell 103 on the top of the inspection vehicle 100 can protect the internal light alarm 204 and horn 205 from dust and collision when the device is not in operation.

[0033] Please see Figure 2 A lead screw 201 is rotatably sleeved at the center of the surface of the guide rail 200. A slider 202 is threaded onto the surface of the lead screw 201. A support plate 203 is fixedly clamped to one side of the surface of the slider 202. A light alarm 204 and a horn 205 are fixedly installed on the top of the support plate 203. A snap-fit ​​plate 206 is fixedly clamped around the outer surface of the support plate 203. A plug-in rod 215 is fixedly installed at the bottom of the snap-fit ​​plate 206.

[0034] The slider 202 moves up and down on the surface of the lead screw 201 via the servo motor 102, and simultaneously drives the support plate 203 to move up and down, so that the top of the smoke sensor 207 contacts the bottom of the baffle 209, and the surface of the smoke sensor 207 is parallel and correspondingly connected to the surface of the grille 210.

[0035] The light alarm 204 and the horn 205 are raised and lowered synchronously inside the inspection vehicle 100 via the support plate 203. The tops of the light alarm 204 and the horn 205 are vertically aligned with the bottom of the protective shell 103, so that the light alarm 204 and the horn 205 are locked inside the protective shell 103.

[0036] In use, after the servo motor 102 starts, it drives the lead screw 201 at the center of the surface of the guide rail 200 to rotate synchronously. The rotation of the lead screw 201 will drive the slider 202, which is threaded on its surface, to slide up and down along the direction of the guide rail 200. The slider 202 then pulls the support plate 203, which is fixedly engaged with it, to complete the lifting and lowering adjustment synchronously. During the rising process of the support plate 203, the smoke sensor 207 on its top will gradually approach and contact the bottom of the baffle 209 on the surface of the guide rail 208, so that the surface of the smoke sensor 207 is parallel, corresponding and connected to the grilles 210 on both sides of the outer surface of the inspection vehicle 100, thereby ensuring that the smoke sensor 207 can be activated. The smoke information in the external environment is collected by the grille 210. At the same time, the light alarm 204 and the horn 205 on the top of the support plate 203 move synchronously with the rise and fall of the support plate 203. When the device is not in operation, the support plate 203 drives the light alarm 204 and the horn 205 to descend into the inspection vehicle 100. When alarm operation is required, the support plate 203 drives the two to rise, so that their tops are vertically aligned with the bottom of the protective shell 103 on the top of the inspection vehicle 100 and locked inside the protective shell 103. This ensures the effective transmission of the sound and light alarm signal and also provides protection for the light alarm 204 and the horn 205 when not in operation.

[0037] Please see Figures 4-6 A water tank 218 is fixedly installed on the bottom inside the inspection vehicle 100. A sealing plate 216 is fixedly installed on the top of the water tank 218. An insertion hole 217 is opened on the surface of the sealing plate 216. An installation plate 212 is fixedly installed on the bottom surface of the inspection vehicle 100. A water outlet pipe 213 is fixedly installed on the bottom of the installation plate 212. A nozzle 214 is fixedly connected to the bottom surface of the water outlet pipe 213.

[0038] The support plate 203 is raised and lowered inside the inspection vehicle 100, which drives the plug rod 215 to rise and fall. The bottom of the plug rod 215 is vertically aligned with the plug hole 217 and passes through the inside of the plug hole 217.

[0039] A water inlet pipe 211 is fixedly installed on one side of the surface of the inspection vehicle 100. One side of the surface of the water inlet pipe 211 is connected to the interior of the water tank 218. A guide rail 219 is fixedly installed on the inner wall of the water tank 218. Positioning plates 221 are slidably installed on both sides of the surface of the guide rail 219. A baffle 220 is fixedly connected to one side of the surface of the positioning plate 221. A pressing block 222 is fixedly installed at the bottom of the baffle 220. A return spring 223 is fixedly installed at the bottom of the pressing block 222.

[0040] One side of the surface of the extrusion block 222 is connected to the interior of the water outlet pipe 213 via the mounting plate 212. The insertion rod 215 passes through the insertion hole 217 and contacts and presses against the surface of the extrusion block 222. The positioning plate 221 drives the baffle 220 to slide and adjust on the surface of the guide rail 219, so that the interior of the water tank 218 is connected to the interior of the water outlet pipe 213. The positioning rod is fixedly installed inside the return spring 223. The insertion rod 215 presses against the extrusion block 222 and contacts and engages with the surface of the positioning rod.

[0041] In use, when the device needs to cool and reduce dust on the ground, the support plate 203 is synchronously raised and lowered under the drive of the servo motor 102, causing the bottom plug rod 215 to descend accordingly. This allows the plug rod 215 to align with and pass through the plug hole 217 on the surface of the sealing plate 216, contacting the surface of the extrusion block 222 inside the water tank 218 and generating extrusion force. This extrusion force pushes the extrusion block 222 downward, simultaneously causing the positioning plate 221 connected to it to slide along the guide rail 219 on the inner wall of the water tank 218. This, in turn, pulls the baffle 220 to move, releasing the blockage between the water tank 218 and the outlet pipe 213, allowing the water tank 218 to move. Water inside the pipe can flow into the outlet pipe 213 through the mounting plate 212 and be sprayed out through the nozzle 214 at the bottom to cool and reduce dust on the ground. At the same time, the pressing block 222 will compress the bottom return spring 223 during the downward movement, and the plug rod 215 will contact and engage with the positioning rod inside the return spring 223 to ensure the stability of the spraying state. After the ground is cooled and dust is reduced, the support plate 203 rises and drives the plug rod 215 to move upward. The elastic rebound force of the return spring 223 will push the pressing block 222, the positioning plate 221 and the baffle 220 to reset, re-seal the connection between the water tank 218 and the outlet pipe 213, and stop the spraying operation.

[0042] Please see Figure 3 Smoke detectors 207 are fixedly installed on both sides of the top surface of the support plate 203. Guide rails 208 are fixedly installed on both sides of the front surface of the smoke detectors 207. Baffles 209 are slidably installed on the surface of guide rails 208. Grilles 210 are fixedly installed on both sides of the outer surface of the inspection vehicle 100.

[0043] When in use, the device can shield the surface of the smoke sensor 207 to prevent dust and debris from affecting the detection sensitivity when it is not in inspection mode. When the device starts inspection operation, as the support plate 203 is raised and lowered by the servo motor 102, the smoke sensor 207 will move synchronously until its top contacts the bottom of the baffle 209 and pushes the baffle 209 to slide open along the guide rail 208. Finally, the surface of the smoke sensor 207 is parallel and connected to the grilles 210 on both sides of the outer surface of the inspection vehicle 100. Smoke in the external environment can smoothly enter the detection range of the smoke sensor 207 through the grilles 210, ensuring that the smoke sensor 207 can effectively and quickly capture the smoke signal, providing a reliable basis for the subsequent alarm and spray function triggering.
