Description

Technical Field

[0001] This utility model relates to the field of fire protection testing equipment technology, and specifically to a fire protection testing equipment. Background Technology

[0002] Smoke detectors automatically issue fire alarms by sensing smoke. Thermal smoke detection is a key fire protection testing device and method specifically designed to test the performance of smoke detectors. It involves using specialized equipment to artificially simulate the thermal smoke environment at the initial stage of a fire, releasing it near the detector to measure the sensitivity, response speed, and system linkage functions of the alarm under simulated fire conditions. Therefore, thermal smoke detection is an important verification method to ensure the reliable operation of fire protection systems such as smoke detectors in real fires, and is commonly used in fire protection acceptance and periodic inspections.

[0003] In the prior art, Chinese Patent CN217109000U discloses a fire detection smoke generator, which relates to the field of fire detection equipment technology. It includes a base with casters at the bottom and a push rod and a fixed cylinder at the top. A sliding groove is formed on the inner wall of the fixed cylinder, and a slider is installed within the groove. An adjusting rod is fixedly connected to one end of the slider, and the adjusting rod is slidably connected inside the fixed cylinder via the slider and the sliding groove. A smoke generator head is installed at the top of the adjusting rod. An adjusting mechanism and an auxiliary support mechanism are provided on the outer wall of the fixed cylinder. This invention simplifies and facilitates the height adjustment of the smoke generator head, improves the detection efficiency of smoke alarms, and enhances the stability of the smoke generator head during operation by providing auxiliary support to the fixed cylinder, effectively reducing the risk of tipping over and resulting in higher overall safety.

[0004] However, in actual use, the above solution still has some shortcomings. After the device is moved to the target position, there is a lack of effective positioning assistance. The operator has to rely entirely on visual inspection to align the hot smoke generator head directly below the high-altitude smoke alarm. The positioning process is cumbersome and prone to deviation, resulting in reduced detection efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a fire detection device to overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fire detection device includes a control console trolley. Two infrared laser positioning components are mounted on the top of the control console trolley. A height adjustment component, a battery, and a smoke generator are all located inside the control console trolley. Each of the two infrared laser positioning components includes an infrared laser indicator, with the emitting ends of both infrared laser indicators pointing vertically upwards. The height adjustment component includes a dual-axis synchronous lifter, a connecting rod, and a rigid tube. The tops of the two lifting rods of the dual-axis synchronous lifter are fixed to the bottoms of the connecting rod. The rigid tube is fixed inside the connecting rod and located between the two infrared laser indicators. The rigid tube is connected to the smoke generator via a telescopic tube.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the top of the control console trolley is provided with a first guide hole, and the top of the control console trolley is provided with two second guide holes. The rigid tube is located above the first guide hole, and the two lifting rods of the dual-axis synchronous lifter pass through the two second guide holes respectively.

[0010] Furthermore, both of the infrared laser positioning components also include a mounting block, and a movable block is slidably connected inside the mounting block, with the infrared laser indicator placed inside the movable block.

[0011] Furthermore, all the mounting blocks have several positioning holes on their right sides, and all the moving blocks have two springs fixedly installed on their right sides. The right sides of the two springs are fixed to the left side of the pull rod. A positioning rod is fixedly installed on the left side of the pull rod. The left side of the positioning rod passes through the moving block and extends into the interior of the positioning hole.

[0012] Furthermore, a support base is fixedly installed inside the console trolley, and the dual-axis synchronous lifter is fixedly installed on the top of the support base.

[0013] Furthermore, a guide plate is fixedly installed inside the console trolley, and the outer side of the telescopic tube is fitted with the outer side of the guide plate.

[0014] Furthermore, the bottom of the hot smoke generator is fixedly equipped with shock-absorbing pads.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] The device is moved below the smoke detector by a mobile control console trolley. The position of the control console trolley is finely adjusted by two infrared laser indicators, which in turn drives the connecting rod to rise under the action of the dual-axis synchronous lifter. This positions the rigid pipe directly below the smoke detector, and the smoke generator allows the smoke to reach directly below the smoke detector through the rigid pipe, improving detection efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4As shown, this utility model provides a fire detection device, including a control console trolley 1. Two infrared laser positioning components 2 are mounted on the top of the control console trolley 1. A height adjustment component 3 is installed inside the control console trolley 1. A battery 4 is installed inside the control console trolley 1. A smoke generator 5 is installed inside the control console trolley 1. Each of the two infrared laser positioning components 2 includes an infrared laser indicator 201, with the light-emitting ends of both infrared laser indicators 201 pointing vertically upwards. The height adjustment component 3 includes a dual-axis synchronous lifter 301, a connecting rod 302, and a rigid tube 303. The tops of the two lifting rods of the dual-axis synchronous lifter 301 are fixed to the bottom of the connecting rod 302. The rigid tube 303 is fixed inside the connecting rod 302 and is located between the two infrared laser indicators 201. The rigid tube 303 is connected to the smoke generator 5 via a telescopic tube 6.

[0025] Battery 4 powers the dual-axis synchronous lift 301 and the smoke generator 5. The infrared laser indicator 201 has a built-in removable battery for easy replacement and maintenance. The bottom of the control console trolley 1 is equipped with two brake casters and two fixed wheels to restrict its position after it reaches the detection point, preventing movement. The emitting ends of the two infrared laser indicators 201 are vertically upward. The operator can adjust the position of the control console trolley 1 by observing the position of the two red dots. The distance between the two red dots emitted by the two infrared laser indicators 201 corresponds exactly to the size of the smoke alarm above, making it easy for the operator to observe. By moving the control buttons on the control console trolley 1, the operator can control the start and stop of the dual-axis synchronous lift 301 and the raising and lowering of the connecting rod 302. This allows the telescopic pipe 6 to be raised and lowered via the rigid pipe 303, facilitating the operation of the smoke generator 5. The connection between the telescopic pipe 6, the rigid pipe 303, and the smoke generator 5 is fixed by hose clamps (not shown in the figure).

[0026] Preferably, the top of the control console trolley 1 is provided with a first guide hole 7, and the top of the control console trolley 1 is provided with two second guide holes 8. The rigid tube 303 is located above the first guide hole 7, and the two lifting rods of the dual-axis synchronous lifter 301 pass through the two second guide holes 8 respectively.

[0027] With this configuration, the two second guide holes 8 facilitate the installation of the two lifting rods of the dual-axis synchronous lifter 301, and the top of each lifting rod is fixed with a connecting block. The connecting block is fixed to the connecting rod 302 by fasteners, which facilitates later maintenance. When the rigid tube 303 rises vertically, it moves through the first guide hole 7 along with the telescopic tube 6.

[0028] Preferably, both infrared laser positioning components 2 further include a mounting block 202, and a movable block 203 is slidably connected inside the mounting block 202, with the infrared laser indicator 201 placed inside the movable block 203.

[0029] This setup allows the distance between the two infrared laser indicators 201 to be adjusted via the moving block 203 according to the size of the smoke detector, facilitating better positioning for subsequent detection.

[0030] Preferably, all mounting blocks 202 have several positioning holes 204 on their right sides, and all moving blocks 203 have two springs 205 fixedly installed on their right sides. The right sides of the two springs 205 are fixed to the left side of the pull rod 206. A positioning rod 207 is fixedly installed on the left side of the pull rod 206. The left side of the positioning rod 207 passes through the moving block 203 and extends into the interior of the positioning hole 204.

[0031] With this configuration, when adjusting the infrared laser indicator 201, the positioning rod 207 is moved out of the positioning hole 204 by pulling the lever 206, thereby adjusting the position of the moving block 203. After adjustment, the lever 206 is released, allowing the positioning rod 207 to re-enter the positioning hole 204, thus restricting the position of the moving block 203 and preventing the distance between the two infrared laser indicators 201 from changing due to a change in the position of the moving block 203 during subsequent movement of the control console trolley 1.

[0032] Preferably, a support base 9 is fixedly installed inside the console trolley 1, and a dual-axis synchronous lifter 301 is fixedly installed on the top of the support base 9.

[0033] This configuration provides an installation location for the dual-axis synchronous lifter 301 via the support base 9, facilitating future maintenance.

[0034] Preferably, a guide plate 10 is fixedly installed inside the console trolley 1, and the outer side of the telescopic tube 6 is attached to the outer side of the guide plate 10.

[0035] This design prevents the telescopic tube 6 from coming into contact with the dual-axis synchronous lifter 301 of the height adjustment component 3, which could cause problems during height adjustment.

[0036] Preferably, a shock-absorbing foot pad 11 is fixedly installed at the bottom of the hot smoke generator 5.

[0037] This configuration improves the stability of the smoke generator 5 during transportation when moving the control console trolley 1, preventing components inside the smoke generator 5 from loosening and causing damage during bumpy rides.
