Description

Technical Field

[0001] This invention relates to the field of fire protection testing technology, and more specifically, to a maintenance and testing system based on monitoring the working status of fire protection power supplies. Background Technology

[0002] As a critical emergency backup power source in a building's fire protection system, the stability of the fire protection power supply directly affects the normal operation of fire alarms, evacuation lighting, fireproof roller shutters, and other fire-fighting equipment. To ensure the reliability of the fire protection power supply, existing technologies typically integrate monitors into its operating circuits to collect parameters such as voltage and current in real time, and trigger buzzer alarms when abnormalities occur, alerting maintenance personnel to handle the situation promptly.

[0003] However, as a highly integrated circuit module, the monitor operates under high voltage and high current conditions for extended periods, making its internal components susceptible to aging, breakdown, or burnout. If the monitor fails, the fire protection power supply will lose its monitoring and protection, creating a safety hazard. Therefore, regular inspection and maintenance of the monitor are crucial.

[0004] To address the aforementioned issues, various monitoring device maintenance procedures have been disclosed in the prior art. For example, Chinese Patent No. CN216562071U proposes a maintenance and testing device for a fire power supply operating status monitor. By setting up a monitoring detection module to continuously monitor the integrated monitoring board, intelligent monitoring is achieved, reducing the frequency of manual inspections and lowering testing costs to some extent.

[0005] However, the device still has the following shortcomings in practical applications: The integrated monitor board is fixedly installed on the inner wall of the power supply box. When the circuit is overloaded and causes partial burnout or breakdown, the box still needs to be opened manually for disassembly and replacement. Due to the limited internal space of the box, it is difficult for operators to quickly disassemble and assemble in a confined environment, resulting in a cumbersome and inefficient maintenance process. Especially in emergency repair scenarios, this prolongs the equipment recovery time and affects the overall reliability of the fire protection system.

[0006] Therefore, how to provide a fire power supply status monitoring system that is easy to install and disassemble with integrated monitoring boards and convenient to maintain has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a maintenance and detection system based on monitoring the working status of fire-fighting power supplies. This system can distinguish between two situations: the detection unit popping out due to a malfunction and the door panel opening under normal conditions.

The structure is ingeniously designed and the operation is smooth.

[0019] 4. During the reset and sliding process of the detection unit, the present invention achieves graded deceleration and buffering of the detection unit through the sequential cooperation of the ball head and multiple buffer parts, avoiding violent collisions with the internal structure of the housing due to excessive sliding speed, effectively protecting the integrated detector board and other precision components, and extending the service life of the equipment.

[0020] 5. This invention can distinguish between two situations: the detection unit pops out due to a malfunction and the door panel is open under normal conditions. When no malfunction occurs, opening the door panel will not trigger the sliding of the detection unit, thus avoiding misoperation. Only in the malfunction state will the detection unit automatically pop out and be further pushed out as the door panel is opened, demonstrating the high level of intelligence and reliability of the system.

[0043] When an overload causes a certain area of ​​the integrated detector board 28 to burn out or break down, the alarm 25 will emit a loud bang. At the same time, the electromagnetic coil 22 will lose power and release the magnetic attraction to the detection unit 3. The rotating door panel 8 will drive the detection unit 3 to slide out from inside the arc-shaped protective shell 6, which will facilitate the quick maintenance and replacement of the integrated detector board 28 on the detection unit 3 and improve the assembly efficiency of the integrated detector board 28.

[0049] A first ear tube 50 is connected to the end of the piston cylinder 9; a second ear tube 51 is connected to the end of the arc-shaped elastic reset airbag; the first ear tube 50 and the second ear tube 51 are connected by a flexible tube; an avoidance groove 52 is provided on the outer wall of the arc-shaped tube 10; an ear seat 53 is fixed on the outer wall of the piston cylinder 9; a sliding opening 54 is provided on the side of the ear seat 53; a vertical plate 75 is fixed between the two rotating rings 29; a horizontal bar 76 that slides with the avoidance groove 52 is fixed on the side of the vertical plate 75; an arc-shaped block 77 that matches the arc-shaped tube 10 is fixed at the end of the horizontal bar 76; the sliding part 12 includes a piston plate 55 that slides with the piston cylinder 9; a connecting rod 56 is fixed on the side of the piston plate 55; a fixing block 57 is fixed at the end of the connecting rod 56; a sliding column 58 that slides with the sliding opening 54 is fixed on the bottom surface of the fixing block 57; a reset spring is connected between the piston plate 55 and the piston cylinder 9.

[0050] A sleeve 59 is fixed to the side of the fixing block 57; a stop rod 60 is slidably arranged inside the sleeve 59; a second spring connects the stop rod 60 and the sleeve 59; a support base 61 is fixed between the tops of the two L-shaped plates 17; an extension rod 62 is fixed to the side of the support base 61; a ball head 63 is fixed to the end of the extension rod 62; an extension plate 64 is fixed to the inner wall of the arc-shaped protective shell 6; several buffer portions 65 are evenly opened on the side of the extension plate 64; the buffer portion 65 includes a sliding strip 66; a triangular guide plate 67 adapted to the ball head 63 is fixed to one end of the sliding strip 66; the sliding strip 66... A stop 68 is fixed to the other end of the moving bar 66; a third spring 69 is sleeved on the sliding bar 66 and connected between the triangular guide plate 67 and the extension plate 64; a sliding groove 70 is opened on the surface of the support base 61; lifting grooves 71 are symmetrically opened on both sides of the inner wall of the sliding groove 70; the lifting part 11 includes a sliding plate 72 that slides with the sliding groove 70; a lifting plate 73 that slides with the two lifting grooves 71 is fixed on the bottom surface of the sliding plate 72; an inclined guide plate 74 that matches the stop bar 60 is fixed on the surface of the sliding plate 72; a support spring is connected between the lifting plate 73 and the lifting groove 71.

[0051] The working principle of this embodiment 2 is as follows: Under normal working conditions, the electromagnetic coil 22 is energized and attracts the armature column 23. The first spring 21 is in a compressed state. Under the elastic action of the supporting spring, the lifting plate 73 is pressed against the top of the lifting groove 71. The inclined guide plate 74 slides out of the groove 70. Under the elastic action of the second spring, the stop rod 60 extends out of the sleeve 59. The baffle 30 on the door panel 8 blocks the arc-shaped protective shell 6. The arc-shaped block 77 squeezes the arc-shaped elastic reset airbag. The arc-shaped elastic reset airbag is squeezed and deformed. The gas in it is forced into the piston cylinder 9, causing the piston plate 55 to move towards the stop block 20. The reset spring is stretched, and the stop rod 60 is placed on one side of the inclined guide plate 74.

[0052] The integrated monitor board 28 is an unencapsulated circuit board, rather than a monitor with an integrated protective casing. The memory 35 contains a sample of the integrated monitor board 28 pre-installed at the factory. The controller 31 periodically activates the camera 32 and flash 33 to photograph the integrated monitor board 28 while it is in operation. The memory 35 compares the photos taken by the camera 32 with the pre-installed samples. When the integrated monitor board 28 is in operation, if an overload causes a certain area of ​​the integrated monitor board 28 to burn out or break down, the photos taken by the camera 32 will not match the samples pre-stored in the memory 35. In this case, the controller 31 will activate the alarm 25 to sound an alarm, eliminating the need for operators to inspect the power supply box and improving the efficiency of the operator's inspection work.

[0053] When an overload causes a certain area of ​​the integrated monitoring board 28 to burn out or break down, the controller 31 controls the alarm 25 to sound an alarm while simultaneously de-energizing the electromagnetic coil 22, releasing the magnetic attraction to the armature post 23. Under the elastic reset action of the first spring 21, the detection unit 3 moves towards the stop bar 60. The inclined guide plate 74 slides down along the slide groove 70 under the blocking and pressing action of the stop bar 60, and the support spring is compressed. As the detection unit 3 continues to move, when the inclined guide plate 74 disengages from the stop bar 60, under the elastic reset action of the support spring, the inclined guide plate 74 slides up and resets. At this time, the stop bar 60 and the inclined guide plate 74 are no longer in contact. When the vertical surface of plate 74 is in contact, the operator rotates the door panel 8, causing the baffle 30 to rotate and disengage from the opening of the arc-shaped protective shell 6, thus opening the power supply box 1. During this process, the arc-shaped block 77 compresses the arc-shaped elastic reset airbag, which is deformed by the compression. The gas inside is forced into the piston cylinder 9, causing the piston plate 55 to slide, thereby moving the stop rod 60. During this process, the stop rod 60 compresses the vertical surface of the inclined guide plate 74, thereby causing the detection unit 3 to slide towards the opening of the power supply box 1. That is, during the rotation and opening of the door panel 8, the detection unit 3 slides out, facilitating the disassembly and assembly of the integrated monitor plate 28 on the detection unit 3.

[0054] When the door panel 8 is fully opened, the insertion rod 40 is coaxially aligned with the two sets of insertion holes 41. Rotating the insertion rod 40 causes it to rotate and descend, inserting into the two insertion holes 41, thus fixing the door panel 8 to the power supply box 1. The damaged integrated monitor board 28 is then removed, and a new integrated monitor board 28 is assembled between the two L-shaped plates 17. Pressing the stop rod 60 causes it to slide and retract into the frame sleeve 59. The second spring is compressed, causing the stop rod 60 to disengage from the vertical surface of the inclined guide plate 74. Under the elastic reset action of the first spring 21, the detection unit 3 moves away from the stop block 20. During this process, the ball head 63 slides and presses the triangular guide plate 67 in sequence. The triangular guide plate 67, pressed by the ball head 63, presses the corresponding third spring 69, thus slowing down the detection unit 3 and preventing it from sliding too fast and causing impact damage, thereby improving the service life of the detection unit 3.

[0055] When the circuit is overloaded and the integrated monitoring board 28 is not damaged, the electromagnetic coil 22 is always energized and attracts the armature post 23 on the detection unit 3. The stop bar 60 is always placed on one side of the inclined guide plate 74. Therefore, when the door panel 8 is rotated and opened, the stop bar 60 gradually moves away from the inclined guide plate 74 and will not drive the detection unit 3 to move.
