Description

Technical Field

[0001] The present invention relates to the technical field of equipment monitoring, and in particular to an electrical equipment overheating monitoring device. Background Art

[0002] With the development of my country's economy, there are more and more electrical equipment, and the use of small enclosed places such as energy storage cabins, electrical cabinets, and computer room data cabinets is increasing, and the frequency is getting higher and higher. After long-term use, the batteries and materials in the equipment will continue to age, the safety performance of the system will decrease, and heat will occur, which will lead to thermal runaway accidents and even fires, posing a safety hazard.

[0003] The monitoring device monitors and analyzes various equipment and systems in real time during use, mainly including temperature monitoring, gas monitoring, particle monitoring, etc. Particle monitoring refers to the detection of tiny solid particles or smoke that may be generated when the system overheats or an overheating event occurs. These particles are usually caused by material combustion, thermal decomposition or other chemical reactions, and may be a precursor to fire. Particle monitoring plays an important role in fire hazard monitoring safety and thermal runaway and early warning.

[0004] Existing overheating monitoring devices are generally installed inside the equipment to monitor the electrical accessories inside the equipment. When monitoring the entire device, it is impossible to detect the specific location where the overheating occurs. After thermal runaway occurs, staff need to carefully find and determine the location before taking measures to eliminate it. The monitoring effect is poor and time-consuming.

[0005] Chinese patent CN216162194U discloses an electrical fire early warning monitoring device for a power distribution cabinet in a power plant, comprising a first shell, a monitoring mechanism and a mounting plate, wherein the monitoring mechanism is arranged at the bottom of the first shell, and the mounting plate is arranged at the right side of the first shell. The electrical fire early warning monitoring device for a power distribution cabinet in a power plant, by installing the monitoring device at the ventilation port of the distribution cabinet, starts the fan to suck air into the interior of the distribution cabinet, draws the air inside the distribution cabinet into the distribution cabinet and discharges the distribution cabinet through the second shell, and the air passes through the smoke sensor inside the second shell and is monitored by the smoke sensor in real time, and starts the fan to speed up the air flow rate inside the distribution cabinet, improves the heat dissipation of the distribution cabinet, and once a fire occurs, the smoke generated by it will be quickly sucked into the second shell and monitored by the smoke sensor, and an alarm will be sounded through the alarm, thereby improving the timeliness of the fire early warning.

[0006] The monitoring method of the above-mentioned patent detects smoke and flames in the area. When smoke or even flames are detected in the area, the fire has already developed to a more serious situation. Therefore, there is an urgent need for a device that can monitor and warn in the very early stage of a fire to improve the anticipation of electrical equipment overheating fault warning.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The monitoring device of the present invention is installed on a guide rail provided in the equipment. The rotation of the fan causes the gas in the equipment to be sucked in from the sampling air inlet of the installation cylinder, filtered through the filter plug plate, and finally enters the detection cavity from the sampling air outlet through the fan cavity. The laser is irradiated into the gas. If there are particles in the gas sample, the laser beam will be scattered by these particles. After the particle detector receives the scattered light signal, it is converted into an electrical signal by the PCB detection board, and data analysis is performed to determine the concentration and size of the particles, which are finally displayed on the display module. This detection helps to monitor possible pollutants or hazardous substances in the gas. The device is also provided with an air outlet channel. The gas in the detection cavity is always flowing, and can be monitored and analyzed in real time. According to the concentration and size of the particles, it can be judged whether there is overheating in the equipment. When overheating occurs, the buzzer sounds to remind the staff to deal with it in time and take corresponding monitoring and control measures, which helps to maintain the stability and safety of the equipment and realize the function of safety monitoring.

[0022] (2) The filter module connected to the air inlet of the fan cavity of the present invention filters the inhaled gas through the filter plate, which can prevent dust in the gas from entering the interior of the device and affecting its use. On the other hand, the filter plug-in plate is installed in a plug-in manner. When the filter plug-in plate is covered with dust and the filtering effect is poor, it can be taken out and replaced so that the device can maintain a good filtering effect.

[0023] (3) The bottom of the lower shell of the present invention can be installed on the guide rail of the equipment by setting a limiting slide groove and a card block. The installation is convenient and can be installed and removed at will, which is highly practical.

[0024] (4) The gas-stabilizing assembly of the present invention, through the arrangement of the motor and the bearing, realizes the detection of the monitoring device in all directions inside the equipment when it rotates clockwise, so as to determine the specific location where overheating occurs, and facilitate the adoption of cooling measures. At the same time, when it rotates clockwise, the motor output shaft is fixedly connected to the base plate, the inner ring of the bearing fixedly connected to the lower shell rotates, and the outer ring of the bearing fixedly connected to the base plate does not rotate. At this time, the shell and the components on the shell begin to rotate, and the movable swivel rotates clockwise along the outer wall of the cam stopper fixed to the outer ring of the bearing. When the movable swivel rotates to the highest point, the spring inside the swivel is compressed, and the T-bar swivel moves It circulates through the highest point of the cam limiter. When it rotates clockwise, the pull rod is not subjected to force, and the elastic arc-shaped shielding cover itself and the arc-shaped elastic rods on both sides open under the action of tension. The four elastic arc-shaped shielding covers form a circular shielding protection cover. While preventing the accessories in the equipment from electromagnetic interference to the detection module, it further prevents the airflow disturbance caused by the corners of the lower shell when the monitoring device rotates, resulting in inaccurate detection data in all directions. It realizes all-round detection and ensures that the detection is not disturbed by airflow. When overheating occurs, it can accurately locate the position where the overheating occurs, with accurate detection data and excellent detection effect.

[0025] (5) When the air stabilizer assembly of the present invention is not in use, it is only necessary to drive the motor to reverse, and the motor drives the shell and the components on the shell to rotate counterclockwise. At this time, when the movable swivel rotates to the highest position of the cam limiter, it is stuck, and the pull rod begins to tighten along the outer ring of the movable swivel. Because the semicircular connecting rods of the four elastic arc-shaped shielding covers are connected in series, after the zipper is tightened, the elastic arc-shaped shielding covers are tightened and all are close to the outer periphery of the shell, so that the operation of the device can be stopped, which is convenient for storage.

DETAILED DESCRIPTION

[0037] The preferred embodiments of the present invention are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0038] Example

[0039] like Figures 1 to 10As shown, an electrical equipment overheating monitoring device comprises a lower shell 100, wherein a detection module 200, a filter module 300 and a power module 400 are installed in the lower shell 100, wherein the detection module 200 is electrically connected to the power module 400; an inner partition 180 is buckled on the lower shell 100, wherein a mainboard PCB600 is mounted on the inner partition 180, wherein the mainboard PCB600 is electrically connected to the power module 400, wherein the mainboard PCB600 is also electrically connected to a display screen module 700, wherein the display screen module 700 is located above the mainboard PCB600; an upper shell 800 is buckled on the lower shell 100, wherein the top of the display screen module 700 is plugged into the upper shell 800; a guide rail mounting plate 900 is rotatably connected to the bottom of the lower shell 100, wherein an air stabilizing component 500 is also installed between the guide rail mounting plate 900 and the lower shell 100;

[0040] The detection module 200 is used to detect whether there is overheating in the device in real time, and performs signal processing through the mainboard PCB, converting the signal into data for display on the display module 700, and the power module 400 supplies power to the device; the cavity between the inner partition 180 and the lower shell 100 is used to install the detection module 200, the filter module 300 and the power module 400, and the cavity between the inner partition 180 and the upper shell 800 is used to install the mainboard PCB600 and the display module 700; the filter module 300 is used to filter the gas entering the detection module 200, and the display screen of the display screen module 700 is plugged into the upper shell 800, and the data on the display screen can be viewed from outside the device; the guide rail mounting plate 900 is used to install the device on the guide rail in the device, and the bottom of the lower shell 100 is rotatably connected to the guide rail mounting plate 900, so that the rotation detection of the monitoring device can be realized. When rotating, the device will generate airflow disturbance, and the air stabilization component 500 is used to control the airflow stability of the rotating monitoring device to reduce the detection error and improve the accuracy of the data.

[0041] The gas stabilizing assembly 500 includes a motor 510 fixed in the middle of the lower shell 100, the output end of the motor 510 passes through the lower shell 100 and is fixedly connected to a guide rail mounting plate 900, a bearing 520 is connected between the lower shell 100 and the guide rail mounting plate 900, the inner ring of the bearing 520 is fixedly connected to the lower shell 100, and the outer ring of the bearing 520 is fixedly connected to the guide rail mounting plate 900; a cam limiter 530 is also fixed on the outer ring of the bearing 520, a movable swivel 540 is sleeved on the cam limiter 530, and the movable swivel 540 is connected to a shielding component 550.

[0042] When in use, the guide rail mounting plate 900 needs to be installed on the guide rail set inside the equipment. Therefore, the guide rail mounting plate 900 is used as a fixed point. Through the setting of the motor 510, the lower shell 100 and the above components are rotated to realize the multi-directional detection function. The bearing 520 is installed between the lower shell 100 and the guide rail mounting plate 900 to increase the supporting force between the two and further make the rotation smoother. The setting of the cam limiter 530 and the movable swivel 540 realizes the opening or closing of the shielding component 550.

[0043] In this embodiment, the shielding component 550 includes four elastic arc-shaped shielding covers 551, one end of the elastic arc-shaped shielding covers 551 is fixed with a round rod 552, and the other end of the elastic arc-shaped shielding covers 551 is fixed with a semicircular connecting rod 553. The four corners of the lower shell 100 are provided with mounting grooves 554. One end of the four elastic arc-shaped shielding covers 551 is fixedly connected in the mounting grooves 554 through the round rods 552 in a one-to-one correspondence, and the other end of the four elastic arc-shaped shielding covers 551 passes through the gap between the adjacent mounting grooves 554 and the round rods 552, and is limited by the semicircular connecting rods 553; both ends of the semicircular connecting rods 553 Through holes are provided, and two pull strips 555 are connected between the four semicircular connecting rods 553. One of the pull strips 555 is connected in series through the through holes provided at the upper ends of the four semicircular connecting rods 553 in sequence, and the other pull strip 555 is connected in series through the through holes provided at the lower ends of the four semicircular connecting rods 553 in sequence. The tails of the two pull strips 555 are merged and passed through the limiting piece 556 provided on the lower shell 100 and then fixedly connected to the movable swivel 540. A limiting bead 557 is fixed on the pull strip 555 between the two adjacent elastic arc-shaped shielding covers 551, and the diameter of the limiting bead 557 is larger than the through hole provided on the semicircular connecting rod 553.

[0044] The elastic arc-shaped shielding cover 551 is used to prevent electromagnetic interference caused by other electrical accessories in the equipment and enhance the detection effect. In addition, on the basis of realizing multi-directional detection of the device through rotation, the rotation between the outer shells of the device will cause airflow disturbance, causing the gas in various directions to mix and unable to be accurately detected. Therefore, the elastic arc-shaped shielding cover 551 is set to be arc-shaped, and four pieces are set to surround the outside of the lower outer shell 100, so that the device as a whole is circular or elliptical, which can avoid the problem of poor detection effect caused by airflow disturbance.

[0045] The round rod 552 is used to install one end of the elastic arc-shaped shielding cover 551 in the installation groove 554, and the other end of the elastic arc-shaped shielding cover 551 passes through the gap between the next installation groove 554 and the round rod 552, and is limited by the semicircular connecting rod 553. The pull strip 555 connects the semicircular connecting rods 553 in series. When the motor drive device is retracted counterclockwise, the limiting bead 557 is used to abut against the semicircular connecting rod 553. When the movable ring 540 rotates to the highest position of the cam limiter 530, it is stuck, and the pull strip 555 begins to tighten along the outer ring of the movable ring 540. Because the four elastic arc-shaped shielding covers 551 are connected in series with each other, after the zipper is tightened, the elastic arc-shaped shielding covers 551 are tightened and are all close to the outer periphery of the shell, so that the operation of the device can be stopped, which is convenient for storage. Specifically, the position of the limiting bead 557 on the pull rod 555 is set according to actual needs to ensure that when the pull rod 555 is tightened, the elastic arc-shaped shielding cover 551 can be tightened and attached to the outer surface of the lower shell 100.

[0046] When rotating in the forward direction, the movable swivel 540 is not constrained by the cam limiter 530, and the pull strip 555 can be quickly loosened. The elastic arc-shaped shielding cover 551 can restore the arc shape due to its own arc shape, and a circular shielding cover can be formed on the outside of the lower shell 100, thereby achieving the effect of stabilizing the airflow during detection, ensuring the accuracy of detection, and realizing multi-directional detection at the same time.

[0047] In this embodiment, arc-shaped elastic rods 558 are fixed to both the upper and lower sides of the elastic arc-shaped shielding cover 551 . The arc-shaped elastic rods 558 are arc-shaped, and one end of the arc-shaped elastic rods 558 is fixed to the round rod 552 .

[0048] When the arc-shaped elastic rod 558 rotates clockwise, it can further enhance the effect of the elastic arc-shaped shielding cover 551 returning to the arc shape, and play a supporting role for the elastic arc-shaped shielding cover 551 .

[0049] In this embodiment, half of the outer arc of the cam limiter 530 is circular, and the other half is an arc with a gradually increasing radius; a groove 541 is provided on the movable swivel 540, and a spring 542 is installed in the groove 541. A T-shaped rod 543 is also installed in the groove 541. The head of the T-shaped rod 543 is limited in the groove 541, and the tail extends out of the groove 541. One end of the spring 542 abuts against the bottom of the groove 541, and the other end abuts against the head of the T-shaped rod 543.

[0050] The setting of the spring 542 and the T-shaped rod 543 ensures that the movable ring 540 is not affected by the cam limiter 530 when the device is detecting, thereby ensuring the shielding cover's effect of stabilizing the airflow. When detection is not needed, the shielding cover of the device can be folded up for easy storage.

[0051] In this embodiment, the detection module 200 includes a detection cavity 220 and a fan cavity 210 connected to the detection cavity 220, and a fan 211 is installed in the fan cavity 210; a light source emitter 230 is installed at one end of the detection cavity 220, a particle detector 240 is installed in the middle of the detection cavity 220, and a PCB detection board 250 is also installed in the detection cavity 220, and the PCB detection board 250 is located above the light source emitter 230 and the particle detector 240, and the detection cavity 220 is covered with a sealed cover 290; the particle detector 240 and the light source emitter are connected to each other.

[0052] The fan 211 rotates, and the gas sucked into the device is filtered by the filter module 300 and enters the fan cavity 210, and the gas is sent to the detection cavity 220 through the air inlet channel. The light source transmitter 230 emits a laser to irradiate the gas. If there are particles in the gas, the laser beam will be scattered by these particles. After the particle detector 240 receives the scattered light signal, it is converted into an electrical signal by the PCB detection board 250, and its intensity and pattern are analyzed. The detection effect is enhanced by the reflector to determine the concentration and size of the particles, and finally displayed on the display module 700. This detection helps to monitor possible pollutants or hazardous substances in the gas, and the device is also provided with an air outlet channel. The gas in the detection cavity is always flowing, and can be monitored and analyzed in real time. According to the concentration and size of the particles, it can be judged whether there is overheating in the equipment. When overheating occurs, the buzzer buzzes to remind the staff to deal with it in time and take corresponding monitoring and control measures, which helps to maintain the stability and safety of the equipment and realize the function of safety monitoring.

[0060] The reflector 260 reflects the scattered light back to the particle detector 240, which can enhance the intensity of the light signal and improve the sensitivity and accuracy of particle detection. The reflector 260 helps collect more scattered light, thereby more accurately measuring the particle concentration in the air.

[0061] In this embodiment, a buzzer is also installed on the mainboard PCB 600 , and the buzzer is electrically connected to the mainboard PCB 600 .

[0063] The working principle of an electrical equipment overheating monitoring device of the present invention is as follows:

[0064] During operation, the motor 510 is first driven to rotate clockwise. At this time, the movable swivel 540 is not limited by the cam limiter 530 and rotates rapidly, so that the pull rod 555 is loosened, and the elastic arc-shaped shielding cover 551 restores its arc shape under the action of its own elastic force and the arc-shaped elastic rod. The four elastic arc-shaped shielding covers 551 form a circular shielding cover on the outside of the lower shell 100 to prevent air flow disturbances; the driving device is turned on for detection, and the rotation of the fan 211 causes the gas in the equipment to be sucked into the mounting cylinder 310 through the air suction threaded joint 130, filtered through the filter plug plate 330, and finally enters the detection cavity 220 through the fan cavity 210 through the sampling outlet 320. The light source transmitter 230 emits a laser to irradiate the gas. If there are particles in the gas, the laser beam will be scattered by these particles, and the particle detector 240 receives the laser. After the scattered light signal is converted into an electrical signal by the PCB detection board 250, data analysis is performed to determine the concentration and size of the particles, and finally displayed on the display module 700; this detection helps to monitor possible pollutants or hazardous substances in the gas, and the device is also provided with an air outlet channel, and the gas in the detection chamber is always flowing, which can be monitored and analyzed in real time; during detection, the device is always rotating, and while rotating, it can detect the gas in various directions in the equipment. According to the concentration and size of the particles, it can be determined whether there is overheating in the equipment. When it rotates to a certain place and detects overheating, it can quickly locate the position, stop rotating, and the buzzer will sound to remind the staff to deal with it in time and take corresponding monitoring and control measures, which helps to maintain the stability and safety of the equipment and realize the function of safety monitoring.
