[0002] In the current high-voltage distribution cabinet spontaneous combustion detection technology, smoke sensors are commonly used for air monitoring. However, this detection method has certain limitations. Specifically, due to the poor air flow inside the distribution cabinet, there are detection blind spots, which limits the detection range of the smoke sensor at the fixed position of the distribution cabinet. When the distribution cabinet spontaneously ignites, it is necessary to wait for the smoke to escape to the location of the sensor before the smoke and combustion conditions can be detected. This detection method is not satisfactory in terms of timeliness, accuracy and efficiency, and often results in the detection of spontaneous combustion conditions not being rapid and accurate enough.

The opposite surfaces of the two middle frames are fixedly connected with a movable support rod, and a guide sleeve is slidably connected to the outside of the movable support rod. The side of the guide sleeve is fixedly connected to the cross plate, and the side of the guide sleeve is fixedly connected to the support. The guide column is slidably connected in the guide groove, and the guide column is set to be cylindrical. An extension rod is fixedly connected to the outside of the middle frame on the upper side, and a squeezing ball is fixedly connected to the bottom end of the extension rod, and the moving path of the squeezing ball can contact the suction and exhaust mechanism.

The bottom end of the vertical pipe is connected to the horizontal pipe, and an air outlet valve is provided outside the vertical pipe.

[0023] A method for using a spontaneous combustion alarm device for a high and low voltage distribution cabinet, the method comprising the following steps:

[0024] First, use the mounting screws to assemble the mounting frame on the side wall inside the power distribution cabinet, and then control the operation of the driving component. The driving component controls the rotation of the reciprocating screw to adjust the movement of the threaded cap, the intermediate frame and the movable support rod. During the movement of the movable support rod, the guide sleeve and the guide column are driven to move. Since the guide column is restricted by the guide groove, the guide sleeve moves in the horizontal direction and moves in the vertical direction along the guide groove at the same time, so that the sensor component can move in the vertical and horizontal directions. While the mounting plate moves in the horizontal direction, it will continuously move closer to or away from the magnetic rod. Since the repulsive force between the magnetic block and the magnetic rod will control the rotation of the rotating rod, the first elastic component is stretched at this time, so that the sensor component moves away from the cross plate. The sensor component detects the inside of the power distribution cabinet along multiple positions, and continuously approaches and moves away from the components inside the power distribution cabinet at the same time, so as to detect the gaps and corners of the components and the power distribution cabinet at multiple angles.

[0025] The sensor component can quickly locate abnormal areas and improve alarm accuracy by detecting data changes at different positions. The movement of the intermediate frame will drive the squeezing ball to move, which will squeeze the contact frame. When the contact frame is pressed and moves downward, it drives the connecting rod and the squeezing plate to move downward. The movement of the squeezing plate squeezes the gas in the gas storage frame and discharges it through the outlet valve, vertical pipe and horizontal pipe. Finally, the gas is discharged through the outlet head and blown. During the separation of the contact frame and the squeezing ball, the second elastic component controls the squeezing plate to move upward, and the gas storage frame draws the gas in the distribution cabinet through the air inlet valve. The gas suction and discharge process realizes the smooth and full flow of gas in the distribution cabinet, and the horizontal plate moves The disturbance plate disturbs the gas flow, making the gas in the distribution cabinet more uniform and avoiding the formation of a detection blind spot due to stagnant air.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, a driving assembly, a reciprocating screw, a cross plate, a movable support rod, a guide sleeve, a guide column, and a guide groove are used. When the driving assembly activates the reciprocating screw rod, the threaded cap and the movable support rod move precisely in the horizontal direction. At the same time, the guide sleeve and the guide column move synchronously with the movable support rod, and under the restriction and guidance of the guide groove, the guide sleeve can move in the vertical direction, thereby realizing the horizontal and vertical composite movement of the sensor assembly; this design greatly improves the detection range, so that the sensor assembly can cover the inside of the distribution cabinet in an all-round way. By collecting data in layers, the device can more comprehensively monitor the fire hazards in the cabinet to ensure that there are no dead angles. The continuous inspection capability of the sensor assembly can form a dynamic distribution diagram of temperature, gas concentration or smoke concentration in real time, providing intuitive data support for fault analysis and early warning.

[0028] 2. In the present invention, a magnetic rod, a magnetic block, a first pin shaft, a second pin shaft and a cross plate are used, and the structural design of the magnetic rod, the magnetic block, the first pin shaft, the second pin shaft and the cross plate is utilized, so that the sensor assembly can move back and forth in the horizontal direction. Thanks to the arrangement of multiple magnetic rods, the magnetic block constantly approaches and moves away from the magnetic rod during the movement, generating a repulsive force; this repulsive force effectively controls the rotation of the rotating rod, thereby driving the sensor assembly to move left and right in the horizontal direction; when the sensor assembly adopts advanced sensor technology such as laser or infrared, its ability to move left and right enables the sensor to emit light at multiple angles, greatly enhancing the coverage and depth of detection. This design enables the sensor assembly to more thoroughly and fully detect the corner areas of the distribution cabinet and the gaps inside the components, ensuring the timely discovery and alarm of potential fire hazards.

[0029] 3. In the present invention, an extrusion plate, an extrusion ball, a contact frame, an extrusion plate, an air outlet valve, an air inlet valve, an air outlet head and a disturbance plate are used. The sensor assembly moves, and the force of the extrusion ball causes the contact frame and the extrusion plate to move downward. When the extrusion ball is separated from the contact frame, the second elastic component quickly resets the extrusion plate. This continuous up and down reciprocating action effectively sucks the gas in the distribution cabinet and introduces it into the gas storage frame; then, the gas in the gas storage frame is squeezed and discharged through the air outlet head, and the disturbance plate pushes and disturbs the gas in the distribution cabinet, ensuring sufficient flow and uniform distribution of the gas in the cabinet. This design effectively avoids the detection blind area formed due to the stillness of the air, thereby ensuring the rapidity and directness of the spontaneous combustion detection. By optimizing the gas flow, not only the detection speed is improved, but also the accuracy of the detection is ensured, greatly reducing the risk of spontaneous combustion accidents.

DETAILED DESCRIPTION

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Please refer to the attached Figure 1 -Attached Fig.10 The present invention provides a technical solution: a spontaneous combustion alarm device for a high and low voltage distribution cabinet, comprising a support 1, wherein sliding grooves 3 are provided on both upper and lower sides of the support 1, a movable support mechanism 4 is slidably connected in the sliding grooves 3, the movable support mechanism 4 is arranged on the support 1, a guide groove 5 is provided on the side of the support 1, the movable support mechanism 4 is slidably connected in the guide groove 5, a horizontal plate 6 is fixedly connected to the side of the movable support mechanism 4, two swing connection mechanisms 7 are fixedly connected to the side of the horizontal plate 6, a fixed rod 8 is fixedly connected to the middle position of the side of the horizontal plate 6, a vertical rod 9 is fixedly connected under the fixed rod 8, a disturbance plate 10 is fixedly connected outside the vertical rod 9, four suction and exhaust mechanisms 11 are fixedly connected outside the support 1, a horizontal pipe 12 is connected under the suction and exhaust mechanism 11, both ends of the horizontal pipe 12 are connected to air outlet heads 14, and a sensor assembly 15 is connected to the side of the swing connection mechanism 7.

[0044] A sensor assembly 15 is used, and the sensor can be a smoke sensor and an optical sensor to detect the gas and temperature in the power distribution cabinet;

[0045] Specifically, Figure 1-3As shown, the support 1 is fixedly connected to the mounting frame 2 on the outside, and the side of the support 1 is fixedly connected to the magnetic rod 16 , and the height of the magnetic rod 16 is greater than the vertical moving path of the sensor assembly 15 .

[0046] Specifically, Figure 1 and Figure 3-4 As shown, a fixing sleeve 13 is fixedly connected to the outside of the transverse tube 12, the fixing sleeve 13 is fixedly connected to the outside of the support 1, the sliding groove 3 is set to be T-shaped, and the guide groove 5 is set to be wavy.

[0047] Specifically, Figure 1-2 and Figure 8-9 As shown, the mobile support mechanism 4 includes a driving component 401 fixedly connected to the support 1 and two intermediate frames 405. The output shaft of the driving component 401 is fixedly connected to a reciprocating screw 402. The other end of the reciprocating screw 402 is sleeved with a bearing seat 403. The bearing seat 403 is fixedly connected to the support 1. The reciprocating screw 402 is externally threaded with a threaded cap 404.

[0048] The threaded cap 404 is connected through the middle frame 405 on the upper side, and the middle frame 405 is fixedly connected to the end close to the support 1 with a sliding block 411, and the sliding block 411 is slidably connected in the sliding groove 3. The opposite surfaces of the two middle frames 405 are fixedly connected with a movable support rod 406, and the movable support rod 406 is slidably connected with a guide sleeve 407 outside. The side of the guide sleeve 407 is fixedly connected to the cross plate 6, and the side of the guide sleeve 407 is fixedly connected to the support 1. The guide column 408 is slidably connected in the guide groove 5, and the guide column 408 is set to be cylindrical. The middle frame 405 on the upper side is fixedly connected to the outside with an extension rod 409, and the bottom end of the extension rod 409 is fixedly connected with a squeezing ball 410, and the moving path of the squeezing ball 410 can contact the suction and exhaust mechanism 11.

[0049] The driving assembly 401 used controls the rotation of the reciprocating screw rod 402, so that the threaded cap 404 and the intermediate frame 405 can be adjusted to move horizontally by utilizing the threaded action. At the same time, the sliding block 411 is guided by the sliding groove 3, so that the movable support rod 406 can move stably in a straight line, and the movable support rod 406 is set to be rectangular, which can ensure that the guide sleeve 407 will not rotate when being driven by the movable support rod 406. At the same time, the guide sleeve 407 can move vertically on the movable support rod 406. Since the guide column 408 is guided by the wavy guide groove 5, the guide sleeve 407 and the cross plate 6 can be controlled to move stably in the vertical direction, and the action of the squeezing ball 410 can be used to perform intermittent squeezing control of the suction and exhaust mechanism 11.

[0050] Specifically, Figure 4-7As shown, the swing connection mechanism 7 includes two rotating rods 71, and a first pin shaft 72 is hinged on the side of the rotating rod 71 near the end. The first pin shaft 72 is arranged on the side of the cross plate 6, and a second pin shaft 73 is hinged on the side of the rotating rod 71 near the other end. The two second pin shafts 73 are hinged to the same mounting plate 74.

[0051] A magnetic block 75 is fixedly connected to the side of the mounting plate 74. The side of the magnetic block 75 close to the magnetic rod 16 has the same magnetism. The sensor component 15 is arranged outside the mounting plate 74. A first elastic component 76 is provided outside the rotating rod 71 away from the fixed rod 8. The other end of the first elastic component 76 is fixedly connected to the side of the cross plate 6.

[0052] By using the magnetic force between the magnetic rod 16 and the magnetic block 75, when the cross plate 6 and the magnetic block 75 move forward and backward with the sensor assembly 15, the magnetic block 75 will continuously approach and then move away from the magnetic rod 16. The magnetic force between the two will control the magnetic block 75 and the sensor assembly 15 to move away from the cross plate 6. At the same time, the magnetic force cooperates with the elastic force of the first elastic component 76 to ensure that the mounting plate 74 moves stably. By using two parallel rotating rods 71 ​​and connecting the first pin shaft 72 and the second pin shaft 73, it is ensured that the sensor assembly 15 will not rotate.

[0053] Specifically, Figure 1-2 and Fig.10 As shown, the suction and exhaust mechanism 11 includes an air storage frame 111 fixedly connected to the side of the support 1, an extrusion plate 112 is slidably connected inside the air storage frame 111, a connecting rod 113 is fixedly connected to the extrusion plate 112, one end of the connecting rod 113 located outside the air storage frame 111 is fixedly connected to a contact frame 114 arranged in an inverted V shape, and a connecting sleeve 115 that penetrates the air storage frame 111 is slidably connected outside the connecting rod 113.

[0054] A second elastic component 116 is fixedly connected under the extrusion plate 112, and the other end of the second elastic component 116 is fixedly connected in the air storage frame 111. The side of the air storage frame 111 is connected to an air inlet valve 117, and the bottom of the air storage frame 111 is connected to a vertical pipe 118. The bottom end of the vertical pipe 118 is connected to the horizontal pipe 12, and an air outlet valve 119 is provided outside the vertical pipe 118.

[0055] The shape of the contact frame 114 can be smoothly squeezed and moved downward by the movable squeezing ball 410. The movement of the intermediate frame 405 drives the squeezing ball 410 to move, which squeezes the contact frame 114. When the contact frame 114 is pressed and moved downward, it drives the connecting rod 113 and the squeezing plate 112 to move downward. The squeezing plate 112 moves and squeezes the gas in the gas storage frame 111 to be discharged through the gas outlet valve 119, the vertical pipe 118 and the horizontal pipe 12. Finally, the gas is discharged and blown through the gas outlet head 14. When the contact frame 114 is separated from the squeezing ball 410, the second elastic component 116 controls the squeezing plate 112 to move upward, and the gas storage frame 111 sucks the gas in the power distribution cabinet through the air inlet valve 117, so that the gas in the power distribution cabinet can flow quickly and evenly.

[0056] A method for using a spontaneous combustion alarm device for a high and low voltage distribution cabinet, the method comprising the following steps:

[0057] First, use the mounting screws to assemble the mounting frame 2 on the side wall inside the power distribution cabinet, and then control the driving assembly 401 to operate. The driving assembly 401 controls the rotation of the reciprocating screw 402 to adjust the threaded cap 404, the intermediate frame 405 and the moving support rod 406. The moving support rod 406 drives the guide sleeve 407 and the guide column 408 to move during the movement. Since the guide column 408 is restricted by the guide groove 5, the guide sleeve 407 moves in the horizontal direction and moves in the vertical direction along the guide groove 5 to realize the sensor assembly. The sensor assembly 15 moves in the vertical and horizontal directions, and while the mounting plate 74 moves in the horizontal direction, it will continuously move closer to or farther away from the magnetic rod 16. Since the repulsive force between the magnetic block 75 and the magnetic rod 16 will control the rotation of the rotating rod 71, the first elastic component 76 is stretched at this time, so that the sensor assembly 15 moves away from the horizontal plate 6. The sensor assembly 15 detects the inside of the power distribution cabinet along multiple positions, and continuously approaches and moves away from the components inside the power distribution cabinet, so that the components and the gaps and corners inside the power distribution cabinet can be detected at multiple angles;

[0058] The sensor assembly 15 can quickly locate abnormal areas and improve alarm accuracy by detecting data changes at different positions. The movement of the intermediate frame 405 drives the squeezing ball 410 to move, which will squeeze the contact frame 114. When the contact frame 114 is pressed and moves downward, it drives the connecting rod 113 and the squeezing plate 112 to move downward. During the movement of the squeezing plate 112, the gas in the gas storage frame 111 is squeezed and discharged through the gas outlet valve 119, the vertical pipe 118 and the horizontal pipe 12. Finally, the gas is discharged and blown through the gas outlet head 14. During the separation of the contact frame 114 and the squeezing ball 410, the second elastic component 116 controls the squeezing plate 112 to move upward, and the gas storage frame 111 sucks the gas in the distribution cabinet through the air inlet valve 117. The gas suction and discharge process realizes the smooth and full flow of the gas in the distribution cabinet, and the movement of the horizontal plate 6 disturbs the gas flow through the disturbance plate 10, so that the gas in the distribution cabinet is more uniform, avoiding the formation of a detection blind spot due to air stagnation.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A spontaneous combustion alarm device for high and low voltage distribution cabinets according to claim 2, characterized in that: The swing connection mechanism (7) comprises two rotating rods (71), a first pin shaft (72) being hingedly connected to a position near one end of a side surface of the rotating rod (71), the first pin shaft (72) being arranged on a side surface of the transverse plate (6), a second pin shaft (73) being hingedly connected to a position near the other end of a side surface of the rotating rod (71), and the two second pin shafts (73) being hingedly connected to the same mounting plate (74) externally.

5. A spontaneous combustion alarm device for high and low voltage distribution cabinets according to claim 4, characterized in that: A magnetic block (75) is fixedly connected to the side of the mounting plate (74); the side of the magnetic block (75) close to the magnetic rod (16) has the same magnetic properties; the sensor component (15) is arranged outside the mounting plate (74); a first elastic component (76) is arranged outside the rotating rod (71) away from the fixed rod (8); an end of the first elastic component (76) away from the rotating rod (71) is fixedly connected to the side of the horizontal plate (6).

6. A method for using a spontaneous combustion alarm device for a high and low voltage power distribution cabinet, according to any one of claims 1 to 5, characterized in that: The method of use comprises the following steps: First, the mounting frame (2) is assembled on the side wall inside the power distribution cabinet using mounting screws, and then the driving assembly (401) is controlled to operate. The driving assembly (401) controls the rotation of the reciprocating screw (402) to achieve the movement of the adjustment threaded cap (404), the intermediate frame (405) and the movable support rod (406). The movable support rod (406) drives the guide sleeve (407) and the guide column (408) to move during the movement. Since the guide column (408) is restricted by the guide groove (5), the guide sleeve (407) moves in the horizontal direction and moves in the vertical direction along the guide groove (5) at the same time, thereby achieving The sensor assembly (15) moves in the vertical direction and the horizontal direction, and while the mounting plate (74) moves in the horizontal direction, it continuously moves closer to or farther from the magnetic rod (16). Due to the repulsive force between the magnetic block (75) and the magnetic rod (16), the rotating rod (71) is controlled to rotate. At this time, the first elastic assembly (76) is stretched, so that the sensor assembly (15) moves away from the horizontal plate (6). The sensor assembly (15) detects the interior of the power distribution cabinet along multiple positions, and continuously moves closer to and farther from the components inside the power distribution cabinet, so that the components and the gaps and corners inside the power distribution cabinet can be detected at multiple angles. The sensor assembly (15) can quickly locate abnormal areas and improve alarm accuracy by detecting data changes at different positions. The movement of the intermediate frame (405) drives the squeezing ball (410) to move, which squeezes the contact frame (114). When the contact frame (114) moves downward under pressure, it drives the connecting rod (113) and the squeezing plate (112) to move downward. The squeezing plate (112) moves to squeeze the gas in the gas storage frame (111) and discharge it through the gas outlet valve (119), the vertical pipe (118) and the horizontal pipe (12). Finally, the gas is discharged through the gas outlet head (14) and the extrusion ball (410) is separated. The second elastic component (116) controls the extrusion plate (112) to move upward, and the gas storage frame (111) sucks the gas in the distribution cabinet through the air inlet valve (117). The gas suction and discharge process enables the gas in the distribution cabinet to flow smoothly and fully. In the process of moving the horizontal plate (6), the gas is disturbed by the disturbance plate (10), so that the gas in the distribution cabinet is more uniform, and the detection blind area is avoided to form when the air is stagnant.
