Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment detection, in particular to a simulation tester for a smoke detector and a temperature detector. Background Art

[0002] In order to protect people's lives and property safety, the state has made relevant specifications and requirements for the supervision of relevant fire protection products and the long-term effectiveness of the continuous operation safety testing of related products. Among them, a special smoke detector and temperature detector simulation tester (hereinafter referred to as the tester) has also been used in the relevant testing market. However, the actual use of the existing tester has many inconveniences and does not meet the design principles of fast, simple, effective and low cost.

[0003] Specifically, the existing tester is powered by the control switch on the host, which starts the heating structure on the host and converts the special smoke oil into smoke or heat energy to achieve the result of the simulation test. Due to the high height of current factories, shopping malls, exhibition halls, office buildings, residences and other buildings, the host must first turn on the control switch, and then use the support rod to send it to the detector for testing. During the transportation process, the device will continue to be turned on, resulting in waste of smoke oil, loss of battery power, and load on the motor. After completing the test of a test area, the support rod must be recovered section by section according to the height of the splicing before the control switch can be turned off and the next test area can be carried out for the same test steps. More than two-thirds of the consumption in the entire test process is useless. Utility Model Content

[0004] The purpose of the utility model is to provide a reasonably designed simulation tester for smoke detectors and temperature detectors in view of the defects and shortcomings of the prior art, which can solve the above-mentioned defects.

[0006] Preferably, the blowing assembly includes a blowing installation shell connected to the top of the support rod, a fan is installed in the blowing installation shell, and the air outlet direction of the fan faces the ventilation duct, and a plurality of air inlets are opened on the blowing installation shell below the fan.

[0007] After adopting the above structure, the beneficial effects of the utility model are:

[0008] This device is designed with a gyro tester. Compared with ordinary testers, the working target has increased by more than three times, the oil loss has been reduced by more than two times, and the fan motor has been given sufficient cooling time, which greatly reduces the probability of overheating and burning. It uses a mercury switch and automatically switches on and off according to the tilt angle. There is no need to remove the support rod, turn off the control switch, etc. The test time is shortened by more than half, and the test efficiency is greatly improved.

[0018] The principle and use process of this utility model:

[0019] When testing is required, the support rod 1 is assembled first, and the angle of the gyro device, that is, the installation angle of the mercury switch 10, is set according to the use requirements. After the installation is completed, a sufficient amount of smoke oil is added to the smoke oil storage chamber 9, the items to be tested are prepared, and the switching switch 3 is adjusted to set the test mode, and then the control switch 2 is pressed. When the angle of the support rod 1 and the gyro device does not reach the set value, the mercury switch 10 is in the disconnected state, and the tester is not powered on. Then the user lifts the support rod 1 to reach the test position, and then adjusts the angle so that the angle of the gyro device reaches the set value, and then the mercury in the mercury switch 10 flows into place, the two electrodes are turned on, and the tester is powered on, and the heating mechanism 1 7 or the heating mechanism 2 11 is started. When the heating mechanism 1 7 is started, the smoke oil will be heated to generate smoke, and at the same time, the fan 6 below rotates, and the airflow rises from the ventilation duct 12, and then the mixed smoke is blown upward to test the smoke detector; when the heating mechanism 2 11 is heated, a local high temperature will be generated, so that the temperature detector can be tested;

[0020] After the test of a single position is completed, the support rod 1 is tilted. As the angle changes, the mercury in the mercury switch 10 automatically flows sideways, thereby detaching from one of the electrodes, and the electrical circuit is automatically disconnected, the circuit is closed, and the tester stops running. The user can directly move the tester to the next position for testing without disassembling and turning on and off the control switch 2.
