Technical Field
[0001] This invention relates to the field of fire protection device testing technology, and in particular to an integrated fire protection device testing equipment and method. Background Technology
[0002] In the field of fire protection equipment production and testing, fire control panels and their supporting detectors, alarms, control buttons and other devices must undergo linkage function testing before leaving the factory to verify the panel's ability to receive, process and control various alarm signals.
[0003] Traditional testing equipment often uses wire harness plug-in or bolt crimping to connect to the fire alarm control panel, requiring manual connection of each terminal, which is complex, time-consuming, and cannot achieve rapid connection and disconnection. Some testing devices using probe crimping structures have probe plates that can only move in one direction, resulting in poor adaptability and incompatibility with fire alarm control panels with different installation orientations and interface types.
[0004] Therefore, it is necessary to provide a testing device and method for integrated fire protection devices to solve the above-mentioned technical problems. Summary of the Invention
[0005] The purpose of this invention is to provide a testing device and method for integrated fire protection devices to solve the technical problems mentioned in the background art.
[0006] Based on the above ideas, the present invention provides the following technical solution: a testing device for integrated fire protection devices, comprising: A needle plate support component, wherein the needle plate support component is elastically fitted with the mounting carrier in the vertical direction, and a base is provided on the top of the needle plate support component; A raised rib, which can move in a vertical direction; The probe plate is hinged to the base, and a connecting rod is hinged between the probe plate and the protrusion. When the base and the needle plate support are locked, the downward movement of the protrusion can cause the probe needle plate to deflect to a horizontal state and maintain the horizontal state while moving vertically, so that the probe can be inserted into the terminal block of the fire alarm control panel.
[0007] As a further aspect of the present invention: when the probe plate is rotated to a vertical position, the base is unlocked from the plate support and locked to the probe plate, so that during the downward movement of the protrusion, the probe plate can be driven to slide horizontally through the connecting rod to insert the probe into the terminal block from a horizontal direction.
[0008] As a further aspect of the present invention: a locking pin is provided on the base, the locking pin is elastically engaged with the base in the vertical direction, and a slot is provided on the top of the needle plate support to engage with the locking pin. Both sides of the probe plate are fixed with pins. The pins pass through the base and rotate with the base. The outer surface of the pin has a pin hole that cooperates with a locking pin. Initially, the bottom end of the locking pin is inserted into the locking groove, so that the base is locked to the probe plate support. When the probe plate is in a vertical position, the locking pin is aligned with the pin hole and inserted into the pin hole to lock the probe plate to the base.
[0009] As a further embodiment of the present invention: a sliding rod is fixed at the bottom of the needle plate support, a protrusion is provided at the mounting carrier, and a clamping bolt is threadedly connected to the protrusion, with one end of the clamping bolt extending to the outer surface of the sliding rod.
[0010] As a further embodiment of the present invention: the top of the needle plate support is provided with a positioning groove, and a positioning block that slides with the positioning groove is fixedly connected to the base.
[0011] As a further aspect of the present invention, both the positioning groove and the positioning block have a T-shaped cross-section.
[0012] As a further aspect of the present invention, it also includes a platform, with the fire control panel and various fire-fighting devices all installed on the top of the platform.
[0013] As a further embodiment of the present invention: side plates are provided on both sides of the top of the platform, and a mounting plate is provided between the two side plates. A slider is fixed on the side of the protrusion near the mounting plate, and the slider slides in cooperation with the mounting plate.
[0014] As a further aspect of the present invention: a screw is provided at the mounting plate, the screw passes through the slider and is threadedly engaged with the slider.
[0015] A testing method based on the aforementioned integrated fire protection device testing equipment includes the following steps: installing the fire control panel and various fire protection devices in place and completing the electrical connection between the fire control panel and the fire protection devices; driving the convex strip to move downward, and through the connecting rod driving the probe pin plate from the initial deflection state to the horizontal state; continuing to drive the convex strip to move downward, so that the probe pin plate remains horizontal and moves downward in the vertical direction until the probe on the probe pin plate is inserted into the terminal block of the fire control panel and a stable electrical crimp is formed.
[0016] Compared with the prior art, the beneficial effects of the present invention are: By setting up a probe pin plate, multiple analog signals can be input to the fire control panel at one time, thus avoiding the need to connect the wiring harness separately and improving the overall testing efficiency. By switching between locking and sliding between the base and the pin plate support, the probe pin plate can flexibly choose between vertical downward pressing or horizontal horizontal insertion according to the interface layout and installation form of the fire control panel. This allows the probe to be reliably inserted into the terminal block of the fire control panel. A single mechanism can simultaneously achieve both vertical and horizontal pin insertion modes, making it compatible with fire control panels of different interface orientations and structural models. This significantly improves the equipment's versatility, adaptability, and ease of on-site operation. Attached Figure Description

[0020] like Figures 1-10 As shown, a testing device for integrated fire protection devices includes a platform 1 for fixing a fire control panel 6 and various fire protection devices 13 (smoke detectors, heat detectors, audible and visual alarms, and alarm bells, etc.). The platform 1 is provided with a bracket for mounting probe plates 14.
[0021] In actual operation, the input end of the probe pin plate 14 is connected to the signal simulation unit, main control unit and feedback acquisition unit of the test equipment through internal wiring. Each signal line preset on its back is connected to the various alarm signal output channels such as smoke, heat, combustible gas and emergency start / stop of the signal simulation unit, as well as the host status feedback and linkage output signal acquisition channels of the feedback acquisition unit. The multiple probes 2 at the output end correspond one-to-one with the power supply, signal input, status feedback, and linkage output terminals of the terminal block 3 of the fire control panel 6. The probe plate 14 can form a reliable electrical crimp with the terminal block 3. After the crimp is completed, the signal simulation unit of the test equipment can input various simulated alarm electrical signals to the fire control panel 6 through the probe plate 14. After receiving the simulated alarm signal, the fire control panel 6 drives various external fire-fighting devices 13 to perform corresponding linkage actions. At the same time, the feedback acquisition unit can acquire the operating status, alarm feedback, and linkage output signals of the fire control panel 6 through the same probe plate 14, realizing the bidirectional transmission of test signals to the host and host status signals to the test equipment, fully simulating the signal transmission and equipment linkage under real fire-fighting conditions, and completing the overall function test and performance verification.
[0022] The various fire-fighting devices 13, fire control panel 6, and electrical connections mentioned in the above scheme are all mature technologies. This scheme will not elaborate on their working principles and specific circuit connections.
[0023] Compared to traditional technical solutions, this solution, by setting up a probe pin plate 14, can input multiple analog signals to the fire alarm control panel 6 at once, thereby avoiding the need to connect the wiring harness separately and improving the overall testing efficiency.
[0024] The aforementioned bracket includes two side plates 4 and a mounting plate 5 fixed between the two side plates 4. The probe plate 14 is mounted between the two side plates 4 and has a state of rotating along a fixed axis and a state of moving linearly in the vertical direction. When the probe plate 14 is in state one, the probe plate 14 can rotate to the inside of the bracket, thereby providing sufficient space for the installation of the fire control panel 6 on the top of the platform 1; and when the probe plate 14 is in state two, the probes 2 on the probe plate 14 can be quickly inserted into the terminals of the terminal block 3 of the fire control panel 6 in the vertical direction, so that the fire control panel 6 can receive different analog signals.
[0025] like Figures 1-4 As shown, a needle plate support 19 for mounting the probe needle plate 14 is provided between the two side plates 4. The needle plate support 19 is elastically engaged with the mounting carrier in the vertical direction. The mounting carrier is either the side plate 4 or the platform 1. Bases 18 are provided on both sides of the top of the needle plate support 19. The bases 18 have a locked state and a sliding state with linear displacement in the horizontal direction relative to the needle plate support 19. The probe needle plate 14 is hinged to the bases 18. A slider 15 is provided on the back of the mounting plate 5. The slider 15 can slide relative to the mounting plate 5 in the vertical direction under the drive of the screw 9. A protrusion 1501 is fixedly connected to the side of the slider 15 away from the mounting plate 5. A connecting rod 17 is hinged between the protrusion 1501 and the probe needle plate 14. The two ends of the connecting rod 17 are respectively hinged to the probe needle plate 14 and the protrusion 1501.
[0026] In one embodiment, the states one and two of the probe plate 14 correspond to the locked states of the base 18 relative to the needle plate support 19. Specifically, in the initial state, the protrusion 1501 pulls the probe plate 14 into the inner side of the bracket through the connecting rod 17, reserving sufficient space for the installation of the fire control panel 6 on the top of the platform 1; as the slider 15 drives the protrusion 1501 to move downward, the connecting rod 17 pushes the probe plate 14 to deflect downward. When the probe plate 14 rotates to a horizontal state, its bottom abuts against the top of the needle plate support 19, and its rotational freedom is restricted; the slider 15 continues to drive the protrusion 1501 to move downward, and the connecting rod 17 pushes the probe plate 14 to remain horizontal and press down in the vertical direction, so that the probe 2 is inserted into the terminal of the terminal block 3 in the vertical direction, realizing the synchronous transmission of multiple simulated alarm signals from the test equipment to the fire control panel 6.
[0027] In another embodiment, when the probe plate 14 is in a vertical state, it has a third state of horizontal displacement, which corresponds to the sliding state of the base 18 relative to the probe plate support 19. Specifically, as shown in Figures 3, 8, and 10, when the protrusion 1501 moves upward and drives the probe plate 14 to deflect upward to a vertical state via the connecting rod 17, the base 18 is unlocked from the probe plate support 19, while simultaneously forming a locking engagement with the probe plate 14; at this time, the screw 9 drives the slider 15 and the protrusion 1501 to move downward, and the connecting rod 17 pushes the probe plate 14 to translate horizontally, so that the probe 2 is inserted into the terminal block 3 of the fire alarm control panel 6 from the horizontal direction, completing the electrical connection.
[0028] In summary, this solution, through the locking / sliding switching between the base 18 and the needle plate support 19, allows the probe needle plate 14 to flexibly choose between vertical downward pressing or horizontal horizontal insertion according to the interface layout and installation form of the fire control panel 6, so that the probe 2 can be reliably inserted into the terminal block 3 of the fire control panel 6. It simultaneously realizes both vertical and horizontal insertion modes on one set of mechanisms, which can be compatible with fire control panels 6 with different interface orientations and different structural models, significantly improving the equipment's versatility, adaptability, and on-site operation convenience.
[0029] Combination Figures 3-7 , Figure 7 The needle plate support 19 is provided with a positioning groove 1901 along the width direction of the platform 1. The bottom of the base 18 is fixed with a positioning block (not shown in the figure) that slides with the positioning groove 1901. It should be noted that the cross-section of the positioning groove 1901 and the positioning block are both T-shaped structures, so that the base 18 and the needle plate support 19 can be stably matched and not separated. Furthermore, the base 18 is provided with a locking pin 21, which is elastically slidingly engaged with the base 18 in the vertical direction; the top of the needle plate support 19 is provided with a slot 1902 that matches the locking pin 21. Pins 20 are fixedly connected to both sides of the probe needle plate 14, the pins 20 pass through the base 18 and rotate with the base 18, and the outer circular surface of the pins 20 is provided with pin holes 2001 that match the locking pin 21. In the initial state, the bottom end of the locking pin 21 is inserted into the slot 1902, keeping the base 18 and the needle plate support 19 locked. When the probe needle plate 14 rotates to the vertical state, the locking pin 21 springs upward under the elastic force, causing the bottom end of the locking pin 21 to disengage from the slot 1902, and the top end of the locking pin 21 to align with and engage with the pin hole 2001, thereby achieving relative locking between the probe needle plate 14 and the base 18. At this time, the protrusion 1501 moves downward in the vertical direction, which can push the probe needle plate 14 to translate in the horizontal direction through the connecting rod 17.
[0030] Combination Figure 3 , Figure 6 As shown, a sliding rod 12 is fixed to the bottom of the needle plate support 19, while a protrusion is fixed to the inner wall of the side plate 4. The sliding rod 12 passes through the protrusion and slides with it. A spring connects the needle plate support 19 and the protrusion, allowing the needle plate support 19 to elastically engage with the side plate 4 in the vertical direction. A clamping bolt 22 is threadedly connected to the protrusion, with one end of the clamping bolt 22 extending to the outer surface of the sliding rod 12.
[0031] According to the above structural configuration, when the base 18 and the needle plate support 19 are locked, the probe needle plate 14 can switch between state one and state two, thereby enabling the probe 2 to be inserted into the terminal block 3 of the fire control panel 6 in a vertical direction; when the base 18 and the needle plate support 19 are unlocked and locked together with the probe needle plate 14 in a vertical state, the vertical position of the needle plate support 19 can be adjusted first, and then the sliding rod 12 can be tightened by tightening the clamping bolt 22 to fix the needle plate support 19 in a vertical direction. After that, the probe needle plate 14 inserts the probe 2 into the terminal block 3 of the fire control panel 6 in a horizontal direction in the form of state three movement.
[0032] Combination Figures 1-3 , Figure 5 As shown, a mounting housing 10 is fixedly connected to the back of the mounting plate 5. The smooth portion of the screw 9 passes through the mounting housing 10 and rotatably engages with it. A rotating shaft 11 is provided on the side of the mounting housing 10 away from the mounting plate 5. The axis of the rotating shaft 11 is coplanar with the axis of the screw 9, and the rotating shaft 11 is perpendicular to the screw 9. Figure 5 As can be seen from the above, the smooth part of the screw 9 is fixedly fitted with a driven bevel gear, while one end of the rotating shaft 11 is provided with a driving bevel gear that meshes with the driven bevel gear; Furthermore, L-shaped plate-like limiting members 16 are provided on both sides of the slider 15. The limiting members 16 are fixedly connected to the mounting plate 5, and a T-shaped channel is formed between the two limiting members 16 to allow the slider 15 to slide, thereby preventing the slider 15 from disengaging from the limiting members 16. The aforementioned screw 9 passes through the slider 15 and is threadedly engaged with it.
[0033] As can be seen from the above structure, through the transmission cooperation between the driving bevel gear and the driven bevel gear, the rotating shaft 11 can drive the screw 9 to rotate, thereby driving the slider 15 to move in the vertical direction.
[0034] To avoid excessive compression between probe 2 and terminal block 3, a sleeve 25 is fixedly installed on the outer end face of the active bevel gear. One end of the aforementioned rotating shaft 11 extends into the sleeve 25 and is threaded into it. The sleeve 25 is elastically engaged with the rotating shaft 11 along its axial direction via an elastic element 24. Furthermore, multiple sets of limiting grooves 2501 are provided on the outer circumferential surface of the sleeve 25 along a direction parallel to its axial direction. These limiting grooves 2501 are distributed in a circumferential array on the outer circumferential surface of the sleeve 25, and both ends of each limiting groove 2501 are chamfered. An elastic telescopic rod 23 is arranged along the diameter of the sleeve 25, and the telescopic rod 23 is fixedly connected to the aforementioned mounting housing 10 via a bracket.
[0035] With this structural design, when probe 2 is inserted into terminal block 3 and in place, the vertical displacement of slider 15 and protrusion 1501 is restricted, and the driven bevel gear and screw 9 can no longer rotate. At this time, if the shaft 11 continues to rotate, the sleeve 25 overcomes the force of elastic element 24 under the threaded engagement of shaft 11 and sleeve 25, driving the driving bevel gear to move away from the driven bevel gear. When the bottom end of telescopic rod 23 is engaged in limiting groove 2501, sleeve 25 is limited and stopped from rotating; continued rotation of shaft 11 will only cause sleeve 25 to move axially. Simultaneously, the chamfered structure at both ends of limiting groove 2501 allows telescopic rod 23 to smoothly exit limiting groove 2501, ensuring the device can be reused.
[0036] In summary, this solution can precisely control the crimping force between probe 2 and terminal block 3 by adjusting the preload of elastic element 24, effectively avoiding damage to probe 2 and terminal block 3 due to excessive compression, and improving crimping reliability and service life.
[0037] A convex ring 1101 is sleeved on the outer side of the rotating shaft 11. The convex ring 1101 and the rotating shaft 11 are rotatably connected by a bearing. The convex ring 1101 and the mounting housing 10 are fixedly connected by a support rod. The elastic element 24 is a spring and is located between the convex ring 1101 and the sleeve 25.
[0038] like Figure 2 As shown, a fixing member 7 is installed on the top of the platform 1, and a limiting block 8 is provided on the inner side of the fixing member 7; a threaded rod passing through the fixing member 7 and threadedly engaged with it rotates with the limiting block 8. The limiting block 8 fits against the top of the platform 1 and is circumferentially limited. Rotating the threaded rod can drive the limiting block 8 to move horizontally, thereby pressing and positioning the fire control panel 6.
[0039] Combination Figure 3 As shown, both the probe plate 14 and the protrusion 1501 are fixed with hinge seats, and the end of the connecting rod 17 is hinged to the corresponding hinge seat through the connecting shaft.
[0040] Combination Figure 7 As shown, the slider 15 has a through hole for the pin 20 to pass through, and a vertical hole for mounting the locking pin 21. The outer surface of the locking pin 21 is integrally formed with a horizontally arranged connecting part 2101. The slider 15 has a slot adapted to the connecting part 2101, and the slot, vertical hole and through hole are interconnected. A spring is provided between the bottom surface of the slot and the connecting part 2101. When the probe plate 14 rotates to the vertical position and the locking pin 21 is aligned with the pin hole 2001, the elastic force of the spring can drive the connecting part 2101 and the locking pin 21 to move upward, so that the top of the locking pin 21 is inserted into the pin hole 2001, thereby locking the pin 20 and the base 18.
[0041] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
