Description

Technical Field

[0001] This utility model belongs to the field of fire detector experimental technology, specifically relating to an experimental instrument for evaluating the function of a building fire protection maintenance detector. Background Technology

[0002] A fire detector functionality tester is a device specifically designed to test and verify the operational status of various types of fire detectors (such as smoke detectors and heat detectors). This instrument simulates real-world fire conditions, such as smoke or heat, to check whether the detectors can accurately respond to and trigger the alarm system. This helps ensure that the fire alarm system within a building is in good working order, enabling timely alerts in real emergencies to protect lives and minimize property damage.

[0003] Problems with existing technology:

[0004] Currently available experimental instruments can only test a single-function detector at a time, which greatly affects their working efficiency. In addition, the installation height of fire detectors in existing experimental instruments cannot be easily adjusted, which affects the accuracy of experimental data. Utility Model Content

[0005] The purpose of this invention is to provide an experimental instrument for evaluating the function of building fire protection maintenance detectors. Through the cooperation of the experimental mechanism and switching components, the instrument can be used without changing the evaluation structure, only the corresponding detector needs to be replaced. At the same time, due to the installation mechanism, various detectors can be easily disassembled and assembled, and the installation height of the detector can be easily adjusted under the action of the cylinder, thereby improving the accuracy of experimental data.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An experimental instrument for evaluating the function of a building fire protection maintenance detector includes a cabinet, wherein a cylinder and a partition are fixedly installed inside the cabinet.

[0008] The cylinder is used to drive the installation mechanism to move vertically, and an experimental mechanism is provided at the bottom of the partition.

[0009] The experimental mechanism includes a base fixedly installed inside the cabinet. A top plate is rotatably installed inside the base via a support rod. A motor is fixedly installed inside the base. The motor drives a transmission unit to rotate a shaft, which in turn drives a switching component to rotate circumferentially via the top plate. A boss is fixedly installed on the top of the base.

[0010] The cabinet has a hinged door on the front, a control box is fixedly installed on one side of the cabinet, and a transparent window is provided on the surface of the cabinet door.

[0011] Multiple support rods are provided and arranged around the top plate and the base. One end of the support rod is rotatably installed with the base, and the other end of the support rod is fixedly installed with the top plate.

[0012] The switching components are provided in three sets, and the switching components are slidably installed with the top plate, while the bottom of the switching components is slidably installed with the base and the boss.

[0013] The switching assembly includes a cylinder, with a guide wheel slidably mounted on the bottom of the cylinder via a connecting rod, a fixing plate fixedly mounted on the surface of the connecting rod, and the top of the fixing plate abutting against the cylinder via a spring.

[0014] A generator is slidably installed inside the cylinder. The bottom of the generator is fixedly installed to the top of the connecting rod. The generator is provided in three sets, namely a smoke generator, a portable hot air gun, and infrared and ultraviolet simulated light sources.

[0015] The installation mechanism includes a mounting base, and a mounting block is fixedly mounted on the bottom of the mounting base via a threaded post. A fire detector is fixedly mounted on the bottom of the mounting block.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes three sets of switching components installed between the top plate and the base. These components house a smoke generator, a portable hot air gun, and infrared and ultraviolet simulated light sources, respectively. The motor activates the transmission unit, which rotates the shaft. This shaft, via the top plate, drives the three sets of switching components to rotate and switch between the three generators, thus achieving automatic switching. Therefore, during use, only the corresponding fire detector needs to be replaced, thereby improving the working efficiency of the experimental instrument.

[0018] This invention utilizes a cylinder installed inside the cabinet. Activating the cylinder drives the installation mechanism to move vertically, thereby adjusting the distance between the installation mechanism and the experimental mechanism, thus improving the accuracy of experimental data. Furthermore, since the installation mechanism is installed at the bottom of the cylinder, and the fire detector is fixedly mounted to the mounting block via a threaded post, the detector can be easily disassembled and replaced under the action of the installation mechanism, further improving experimental efficiency.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, an experimental instrument for evaluating the function of a building fire protection maintenance detector includes a cabinet 1, and a cylinder 4 and a partition 6 are fixedly installed inside the cabinet 1.

[0028] Cylinder 4 is used to drive the installation mechanism 5 to move vertically, and experimental mechanism 7 is provided at the bottom of partition 6;

[0029] The experimental mechanism 7 includes a base 71 fixedly installed inside the cabinet 1. A top plate 73 is rotatably installed inside the base 71 via a support rod 72. A motor 77 is fixedly installed inside the base 71. The motor 77 drives the transmission part 76 to rotate the shaft 75, so that the shaft 75 drives the switching component 74 to rotate circumferentially via the top plate 73. A boss 78 is fixedly installed on the top of the base 71.

[0030] See attached document Figure 2 , Figure 3 and Figure 4 In this embodiment, a cabinet door 2 is hinged to the front of the cabinet 1, a control box 3 is fixedly installed on one side of the cabinet 1, and a transparent window is provided on the surface of the cabinet door 2.

[0031] In the above embodiment, the cabinet door 2 can seal the cabinet 1, thereby preventing smoke from escaping from the interior of the cabinet 1 during the experiment on the detector, while the experiment can also be viewed through the transparent window of the cabinet door 2.

[0032] Furthermore, the detectors correspond to experimental unit 7, and are respectively a smoke detector, a temperature detector, and a flame detector.

[0033] Specifically, the experimental mechanism 7 has multiple support rods 72, which are arranged around the top plate 73 and the base 71. One end of the support rod 72 is rotatably installed with the base 71, while the other end of the support rod 72 is fixedly installed with the top plate 73. Therefore, the support rod 72 can provide support for the top plate 73.

[0034] It should be noted that there are three sets of switching components 74, and the switching components 74 are slidably installed with the top plate 73, while the bottom of the switching components 74 is slidably installed with the base 71 and the boss 78. At the same time, the three sets of switching components 74 correspond to the smoke detector, the temperature detector and the flame detector respectively, so as to realize the evaluation experiment of multiple detector functions.

[0035] Please refer to the appendix for details. Figure 3 and Figure 4 The switching assembly 74 includes a cylinder 741 slidably mounted inside the top plate 73. A guide wheel 746 is slidably mounted on the bottom of the cylinder 741 via a connecting rod 743. When the guide wheel 746 moves along the base 71 and the boss 78, the connecting rod 743 can push the generator 742 to move vertically.

[0036] In addition, since a fixing plate 744 is fixedly installed on the surface of the connecting rod 743, and the top of the fixing plate 744 abuts against the cylinder 741 through a spring 745, when the guide wheel 746 leaves the surface of the boss 78, the guide wheel 746 can be pushed to abut against the base 71 by the reset of the spring 745.

[0037] It is worth noting that a generator 742 is slidably installed inside the cylinder 741. The generator 742 is provided with three sets, namely a smoke generator, a portable hot air gun, and infrared and ultraviolet simulated light sources. At the same time, the generator 742 corresponds to the smoke detector, temperature detector and flame detector installed at the bottom of the mounting mechanism 5, thereby realizing the detector function evaluation experiment.

[0038] See attached document Figure 1 , Figure 2 and Figure 5 In this embodiment, the installation mechanism 5 includes a mounting base 51, and a mounting block 52 is fixedly installed on the bottom of the mounting base 51 by a threaded post 54. A fire detector 53 is fixedly installed on the bottom of the mounting block 52.

[0039] In the above embodiment, the mounting block 52 is located between the fire detector 53 and the mounting base 51. At the same time, four sets of waist-shaped through holes are arranged around the surface of the mounting block 52, so that various detectors can be fixedly installed to the mounting block 52 by bolts.

[0040] Furthermore, the fire detector 53 can be installed at the bottom of the mounting base 51 by means of the threaded post 54 on the top of the mounting block 52, thereby realizing convenient installation and removal of various detectors. At the same time, since the top of the mounting mechanism 5 is equipped with a cylinder 4, the cylinder 4 can push the mounting mechanism 5 to adjust the distance between it and the experimental mechanism 7, thereby enriching the experimental data and improving the accuracy of the experimental data.

[0041] The working principle of this utility model is as follows: After the fire detector 53 is fixed to the mounting block 52 by using bolts, and the mounting block 52 is installed with the mounting base 51 by the threaded post 54, the fire detector 53 can be installed. Then, the cylinder 4 can be started to push the fire detector 53 to move vertically to the set height. The motor 77 drives the transmission part 76 to rotate the shaft 75, and the shaft 75 drives the top plate 73 and the switching assembly 74 to rotate circumferentially. When the switching assembly 74 moves along the top of the base 71 to the top of the boss 78, the generator 742 can be pushed upward by the action of the switching assembly 74. Then, by turning off the motor 77, the generator 742 is kept stationary. The generator 742 can be started by the control box 3 to conduct an evaluation experiment on the fire detector 53.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
