[0048] Example 1

[0049] See also Figure 1The present invention discloses a detector testing device, which includes a simulation component 1, a first adjustment unit 2 and an extension component 3.

[0050] The simulation component 1 includes a temperature trigger unit 11 and a smoke trigger unit 12. The temperature trigger unit 11 is used to simulate the triggering condition of the temperature detector to test whether the temperature detector can issue a temperature alarm. Figure 4 a and Figure 4 As shown in FIG. 1 , the temperature-sensing trigger unit 11 is a magnetic ring. It should be noted that a test switch is usually provided in the temperature detector, which can be triggered by an external magnet. Therefore, when the temperature-sensing trigger unit 11 is close to the temperature detector, the test switch of the temperature detector can be triggered. If the temperature detector issues a temperature alarm, it indicates that the temperature detector can work normally. If the temperature detector does not issue a temperature alarm, it is necessary to repeat the test of the temperature detector. If the temperature alarm still cannot be issued in the repeated test, it indicates that the temperature detector needs to be repaired or replaced.

[0051] In addition, the smoke trigger unit 12 is used to simulate the triggering conditions of the smoke detector to test whether the smoke detector can send out a smoke alarm. Figure 4 b. Figure 5 d and Figure 5 As shown in Figure e, the smoke trigger unit 12 is an aerosol spray bottle. A nozzle 121 and a pressing portion 122 are provided at the upper end of the aerosol spray bottle, and the pressing portion 122 is connected to the nozzle 121. When the pressing portion 122 of the smoke trigger unit 12 is subjected to downward pressure, the aerosol spray bottle sprays aerosol through the nozzle 121. The aerosol is suspended in the air and can trigger the smoke detector. If the smoke detector sends out a smoke alarm, it indicates that the smoke detector can work normally; if the smoke detector does not send out a smoke alarm, it is necessary to repeat the test of the smoke detector. If the smoke alarm still cannot be sent out during the repeated test, it indicates that the smoke detector needs to be repaired or replaced.

[0052] Furthermore, since the installation positions of smoke detectors and heat detectors in the factory are relatively high, and even most of the smoke detectors and heat detectors are installed on the ceiling of the factory, in order to facilitate the staff to conduct simulation tests of the detectors, the simulation component 1 is connected to the extension component 3 through the first adjustment unit 2. The first adjustment unit 2 can adjust the angle between the simulation component 1 and the extension component 3, and the extension component 3 can be extended so that the simulation component 1 is close to the heat detector / smoke detector directly above or obliquely above.

[0053] Specifically, when conducting a simulation test of the temperature detector, the staff needs to extend the extension component 3 to a sufficient length so that the temperature trigger unit 11 in the simulation component 1 is close to the temperature detector, and the simulation test of the temperature detector can be completed. If there is an obstruction below the temperature detector, the staff needs to stand diagonally below the temperature detector and adjust the angle between the simulation component 1 and the extension component 3 so that the temperature detector can approach the temperature detector from the side, and then complete the simulation test of the temperature detector.

[0054] It should be noted that the existing temperature-sensing trigger unit is usually a heating wire, which triggers the temperature detector by heating the heating wire. However, during the test, the heating wire needs to be powered by a mobile power supply to continue to heat up. This results in the existing temperature-sensing trigger unit being heavy, which is inconvenient for staff to perform test operations. This test device uses a magnetic ring as a temperature-sensing trigger unit, which does not require power supply, and can trigger the test switch in the temperature detector through magnetism, making it more convenient for staff to perform test operations.

[0055] In addition, when conducting a simulation test of the smoke detector, the staff needs to extend the extension component 3 to a length sufficient to reach the ceiling, and make the nozzle 121 of the smoke trigger unit 12 face the smoke detector, then push the smoke trigger unit 12 upward to the ceiling of the factory building, press the pressing part 122 of the smoke trigger unit 12 through the ceiling, and then make the smoke trigger unit 12 spray aerosol toward the smoke detector to conduct a simulation test of the smoke detector.

[0056] It should be noted that, when conducting the simulation test of the smoke detector, in order to facilitate the application of pressure to the pressing part 122 through the ceiling of the factory building, the smoke trigger unit 12 needs to always remain in a vertically upward state. For example, when there is an obstruction below the smoke detector, the staff stands diagonally below the smoke detector, extends the extension component 3 so that the smoke trigger unit 12 can approach the smoke detector from the side, and then adjusts the angle between the simulation component 1 and the extension component 3 so that the smoke trigger unit 12 is vertically upward, and then moves the smoke trigger unit 12 upward until it abuts against the ceiling, and applies pressure to the pressing part 122 through the ceiling, so that aerosol is sprayed out of the smoke trigger unit 12, so as to complete the simulation test of the smoke detector.

[0057] It should also be noted that the existing smoke trigger unit is usually an atomizer, but the atomizer needs to be powered and needs to be charged before use, which is cumbersome. This test device uses a press-type aerosol spray bottle as the smoke trigger unit, which does not require power supply and is convenient for staff to perform test operations.

[0058] Therefore, this detector test device can perform simulation tests on smoke detectors and heat detectors that are located in high, remote, and difficult-to-reach locations in the factory.

[0059] See also Figure 4 a and Figure 4 b. In this embodiment, the simulation component 1 further includes a mounting shell 13 , which is mounted on the upper end of the first adjustment unit 2 . The temperature trigger unit 11 is mounted on the upper end of the mounting shell 13 , and the smoke trigger unit 12 is accommodated inside the mounting shell 13 .

[0060] Specifically, the mounting shell 13 includes a sleeve 131, a sliding ring 132 and a cover 133. The sleeve 131 is fixedly connected to the upper end of the first adjustment unit 2, the sleeve 131 has an upward opening, and the smoke trigger unit 12 is partially accommodated in the sleeve 131. The cover 133 is located directly above the smoke trigger unit 12, and the temperature trigger unit 11 is installed on the top of the cover 133. The cover 133 is connected to the sleeve 131 through the sliding ring 132. The sliding ring 132 is wound around the upper end of the sleeve 131 and is slidably connected to the upper end of the sleeve 131. The sliding ring 132 can move up and down relative to the sleeve 131. The cover 133 is threadedly connected to the sliding ring 132, so the cover 133 can move synchronously with the sliding ring 132. As shown in FIG. Figure 5 As shown in FIG. 1 , a first through hole 134 is formed on the side wall of the cover 133. The nozzle 121 of the smoke trigger unit 12 passes through the first through hole 134. When the cover 133 is pressed and moved downward, it can press the pressing portion 122 of the smoke trigger unit 12, thereby causing the nozzle 121 to spray out aerosol. When conducting a simulation test of a smoke detector, the staff only needs to keep the simulation component 1 in a vertically upward state, and then move the simulation component 1 upward to abut against the ceiling, so that the cover 133 is pressed and moved downward, so that the pressing portion 122 can be pressed, thereby causing the nozzle 121 to spray out aerosol.

[0061] More specifically, if Figure 5 a. Figure 5As shown in FIG. 3 , a second through hole 135 is provided at the upper end of the side wall of the sleeve 131. The second through hole 135 is in the shape of a long strip and extends along the axial direction of the sleeve 131. There are four second through holes 135, which are evenly arranged around the circumference of the sleeve 131. A third through hole 136 is provided on the side wall of the sliding ring 132. There are also four third through holes 136, which are evenly arranged around the circumference of the sliding ring 132, and the third through holes 136 are aligned one by one with the second through holes 135. In addition, the mounting housing 13 also includes four positioning bolts 14, which penetrate the second through hole 135 and the third through hole 136, and are used to guide the sliding ring 132 to move along the axial direction of the sleeve 131, and limit the sliding ring 132 from rotating relative to the sleeve 131, so that the sliding ring 132 can move up and down relative to the sleeve 131.

[0062] Furthermore, an elastic member 15 is also accommodated in the sleeve 131. The elastic member 15 is located between the smoke trigger unit 12 and the bottom of the sleeve 131. The smoke trigger unit 12 is elastically connected to the bottom of the sleeve 131 through the elastic member 15. Specifically, the elastic member 15 is a compression spring. When the cover 133 is under pressure, it will transfer the pressure to the smoke trigger unit 12 and the elastic member 15, so that the elastic member 15 is compressed and generates elastic potential energy. After the simulation test of the smoke detector is completed, the staff moves the simulation component downward. At this time, the cover 133 is no longer under pressure, and the elastic potential energy of the elastic member 15 is converted into an upward elastic force, so that the smoke trigger unit 12 and the cover 133 return to their original positions. By arranging the elastic member 15 between the smoke trigger unit 12 and the bottom of the sleeve 131, the cover 133 and the smoke trigger unit 12 can automatically return to their original positions after each pressing, which is convenient for the next pressing.

[0063] In addition, it is difficult for the staff to control the force when moving the simulation unit upward to make the cover 133 contact the ceiling. If too much force is used, the smoke trigger unit 12 may be damaged. Therefore, the elastic member 15 can remove the impact force generated when the cover 133 contacts the ceiling to avoid damage to the temperature trigger unit 11.

[0064] Furthermore, an adjusting screw is provided on the top of the cover 133, and the adjusting screw extends downward and passes through the top of the cover 133. The lower end of the adjusting screw abuts against the pressing portion 122 of the smoke trigger unit 12 to apply an initial pressure to the pressing portion 122 of the smoke trigger unit 12, so that the pressure is directly transmitted to the pressing portion 122 when the cover 133 is pressed. The staff can adjust the initial pressure of the pressing portion 122 by adjusting the depth of the adjusting screw.

[0065] See also Figure 6 a and Figure 6b. In this embodiment, the first adjustment unit 2 includes a first upper connecting section 21 and a first lower connecting section 22. The first lower connecting section 22 is tubular. The first upper connecting section 21 is fixedly connected to the simulation component 1, and the first lower connecting section 22 is connected to the extension component 3. The first upper connecting section 21 is rotatably connected to the first lower connecting section 22. Specifically, Figure 7 a. Figure 7 b. Figure 7 As shown in FIG. 3 , the lower end of the first upper connecting section 21 is elastically connected to two first ear plates 23, and the first ear plates 23 extend downward. Figure 8 a. Figure 8 b. Figure 8 As shown in FIG. 3 , the first lower connecting section 22 is provided with a first hinged portion 24 at the upper end thereof, and two first ear plates 23 are respectively located at the left and right sides of the first hinged portion 24. The first adjusting unit 2 also includes two first hinged shafts 25, which respectively penetrate through the two first ear plates 23 and are respectively connected to the left and right ends of the first hinged portion 24, so that the first upper connecting section 21 is hinged to the first lower connecting section 22. Figure 6 As shown in FIG. 2 , the first hinge shaft 25 is fixed to the first hinge part 24 by a set screw, which is coaxially arranged with the first hinge shaft 25, passes through the first hinge shaft 25, and is threadedly connected to the first hinge part 24. The outer sides of the two first hinge shafts 25 are each provided with a first fastening portion 26 extending in the vertical direction, and the two first fastening portions 26 are respectively used to press the two first ear plates 23 to the first hinge part 24.

[0066] When it is necessary to adjust the angle between the simulation component 1 and the extension component 3, the staff only needs to loosen the fixing screw, and the first upper connecting section 21 can rotate around the axis of the first hinge shaft 25. After adjusting to a suitable angle, tighten the fixing screw so that the first ear plate 23 is close to the first hinge part 24, and the first upper connecting section 21 and the first lower connecting section 22 can be fixed by friction.

[0067] See also Fig. 9 a. Fig. 9 b. In this embodiment, the extension assembly 3 includes an extension rod 31 and a V-shaped spring piece 32. The extension rod 31 extends in the vertical direction. The extension rod 31 is tubular, and its upper end is inserted into the first lower connecting section 22. Figure 8 b. Figure 8 As shown in FIG. 3 , the side wall of the lower end of the first lower connecting section 22 is provided with a first card interface 27. The side wall of the upper end of the extension rod 31 is correspondingly provided with a second card interface 331. The V-shaped spring piece 32 is inserted into the extension rod 31 and is located at the upper end of the extension rod 31. A positioning protrusion 321 is provided on the outer side thereof. The positioning protrusion 321 penetrates the first card interface 27 and the second card interface 331 to fix the extension rod 31 and the first lower connecting section 22 together.

[0068] Specifically, the number of the extension rods 31 in the extension assembly 3 is multiple sections, and the multiple sections of the extension rods 31 are connected in sequence along the vertical direction. The number of the extension rods 31 needs to be determined according to the height of the temperature detector / smoke detector. Specifically, the lower end side wall of the extension rod 31 is provided with a third card interface 341, and the portion of the extension rod 31 located below is inserted into the extension rod 31 located above, and the second card interface 331 of the lower extension rod 31 is aligned with the third card interface 341 of the upper extension rod 31. The number of V-shaped spring clips 32 in the extension assembly 3 is also multiple. A V-shaped spring clip 32 is inserted in each section of the extension rod 31, and the positioning protrusion 321 on the V-shaped spring clip 32 in the lower extension rod 31 passes through the second card interface 331 and the third card interface 341 to fix the two adjacent extension rods 31.

[0069] Furthermore, the extension rod 31 includes a round tube 34 and a connecting tube 33, both of which extend in the vertical direction, and the connecting tube 33 is fixedly connected to the upper end of the round tube 34. The second card interface 331 is located at the upper end of the connecting tube 33, and the V-shaped spring piece 32 is inserted into the connecting tube 33. The third card interface 341 is located at the lower end of the round tube 34.

[0070] It is easy to understand that the extension rod 31 can be connected to the first adjustment unit 2, and can also be connected to other extension rods 31. When the extension rod 31 is connected to the first adjustment unit 2, the upper end of its connecting tube 33 is inserted into the first lower connecting section 22, so that the positioning protrusion 321 of the V-shaped spring 32 passes through the first card interface 27 and the second card interface 331. When the extension rod 31 is connected to the extension rod 31 located above, its connecting tube 33 is inserted into the round tube 34 of the extension rod 31 located above, so that the positioning protrusion 321 passes through the second card interface 331 and the third card interface 341.

[0071] See also Fig.10 a and Fig.10 b, the extension assembly 3 further includes a second adjustment unit 35. The second adjustment unit 35 includes a second upper connecting section 351 and a second lower connecting section 353, and the second upper connecting section 351 is rotatably connected to the second lower connecting section 353. Fig.11 a. Fig.11 b and Fig.11As shown in FIG. 3 , the lower end of the second upper connecting section 351 is elastically connected with two second ear plates 352, and the second ear plates 352 extend downward.

[0072] like Figure 2 As shown, in some embodiments, the second adjustment unit 35 is located between the first lower connecting section 22 and the extension rod 31, and is used to adjust the angle between the first lower connecting section 22 and the extension rod 31.

[0073] Specifically, the second upper connecting section 351 is tubular, and a fourth card interface 357 is provided on the side wall of the second upper connecting section 351. The second upper connecting section 351 is inserted into the first lower connecting section 22 so that the fourth card interface 357 is aligned with the first card interface 27. A V-shaped spring piece is inserted into the second upper connecting section 351, and the positioning protrusion of the V-shaped spring piece passes through the first card interface 27 and the fourth card interface 357, so that the second upper connecting section 351 and the first lower connecting section 22 are fixed together.

It should be noted that Figure 3The connection form of the detector test device shown is particularly suitable for the case where the shielding object below the smoke detector / heat detector is large in size. The staff can adjust the angle between the two extension rods 31 through the second adjustment unit 35 to increase the horizontal offset distance between the staff's standing position and the simulation component 1, making it easier for the staff to perform simulation tests on the smoke detector / heat detector located above the shielding object.

[0075] Example 2

[0076] The present invention discloses a detector testing method, which is applied to the detector testing device in Example 1. The testing method comprises the following steps: adjusting the angle between the simulation component 1 and the extension rod 31 by the first adjustment unit 2. By extending the extension component 3, the simulation component 1 is brought close to the temperature detector / smoke detector directly above or obliquely above the simulation component 1. The temperature trigger unit 11 of the simulation component 1 triggers the test switch in the temperature detector by magnetic means to test whether the temperature detector can issue a temperature alarm. The smoke trigger unit 12 of the simulation component 1 triggers the smoke detector by spraying aerosol, thereby testing whether the smoke detector can issue a smoke alarm.

[0077] Specifically, when conducting a simulation test of the temperature detector, the staff needs to extend the extension component 3 to a sufficient length so that the temperature trigger unit 11 in the simulation component 1 is close to the temperature detector, and the simulation test of the temperature detector can be completed. If there is an obstruction below the temperature detector, the staff needs to stand diagonally below the temperature detector and adjust the angle between the simulation component 1 and the extension component 3 so that the temperature detector can approach the temperature detector from the side, and then complete the simulation test of the temperature detector.

[0078] When conducting a simulation test of a smoke detector, the staff needs to extend the extension component 3 to a length sufficient to reach the ceiling, and make the nozzle 121 of the smoke trigger unit 12 face the smoke detector, then push the smoke trigger unit 12 upward to the ceiling of the factory, press the pressing part 122 of the smoke trigger unit 12 through the ceiling, and then make the smoke trigger unit 12 spray aerosol toward the smoke detector to conduct a simulation test of the smoke detector. If there is an obstruction below the smoke detector, the staff stands diagonally below the smoke detector, extends the extension component 3 so that the smoke trigger unit 12 can approach the smoke detector from the side, then adjusts the angle between the simulation component 1 and the extension component 3 so that the smoke trigger unit 12 is vertically upward, and then moves the smoke trigger unit 12 upward to abut against the ceiling, and applies pressure to the pressing part 122 through the ceiling, so that the smoke trigger unit 12 sprays aerosol, so as to complete the simulation test of the smoke detector.

[0079] Therefore, this method can effectively simulate the test of smoke detectors and heat detectors.

[0080] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
