Description

Technical Field

[0001] This application relates to the technical field of electrical control cabinets, and more particularly to an intelligent electrical control cabinet for fire protection. Background Art

[0002] An electrical control cabinet is a device that assembles switches, protection appliances, etc. in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements of normal operation, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment.

[0003] Currently, when an electrical control cabinet for fire protection is in use, in order to reduce the temperature inside the electrical control cabinet and ensure normal operation, a cooling device usually needs to be installed inside the electrical control cabinet. A common cooling device for an electrical control cabinet is to open heat dissipation windows on the side walls of the electrical control cabinet and install heat dissipation fans to accelerate the air flow speed inside the electrical control cabinet, thereby reducing the temperature inside the electrical control cabinet and ensuring the normal operation of the electrical control cabinet for fire protection.

[0004] However, when the electrical control cabinet for fire protection is used outdoors, in rainy weather, rainwater is likely to enter the inside of the electrical control cabinet through the heat dissipation windows, which is likely to cause a short circuit in the internal circuit of the electrical control cabinet. Utility Model Content

[0005] In order to improve the safety of the electrical control cabinet for fire protection, this application provides an intelligent electrical control cabinet for fire protection.

[0006] An intelligent electrical control cabinet for fire protection provided by this application adopts the following technical solutions:

[0007] An intelligent electrical control cabinet for fire protection includes a cabinet body, two sets of heat dissipation windows opened on opposite side walls of the cabinet body for ventilation and heat dissipation of the cabinet body, and a rain shielding mechanism arranged on the cabinet body for blocking rainwater from entering the heat dissipation windows. The rain shielding mechanism includes:

[0008] A slide rail, which is arranged on the cabinet body;

[0009] A flexible steel sheet, which is slidably arranged on the slide rail. The flexible steel sheet can slide along with the slide rail and undergo elastic deformation to block rainwater from entering the heat dissipation windows;

[0010] A driving component, which is arranged on the cabinet body and used to drive the flexible steel sheet to slide along with the slide rail.

[0011] By adopting the above technical solution, the heat dissipation window is used to dissipate heat from the interior of the cabinet. When it rains, after the driving component detects raindrops, it drives the flexible steel sheet to slide within the slide rail, and finally blocks the rainwater from entering the heat dissipation window through the flexible steel sheet, reducing the probability of rainwater entering the cabinet. At the same time, after the rain stops, the driving component drives the flexible steel sheet to move back, ensuring the heat dissipation effect of the heat dissipation window and improving the safety of the electrical control cabinet for fire protection.

[0012] Further, the slide rail includes a vertical section and an arc section. The vertical section and the arc section are adjacent to each other. The flexible steel sheet slides within the vertical section and the arc section, and the flexible steel sheet undergoes elastic deformation along with the arc section when sliding within the arc section.

[0013] By adopting the above technical solution, after the front end of the flexible steel sheet slides from the vertical section into the arc section, an arc structure is formed to block rainwater from entering the heat dissipation window.

[0014] Further, the driving component includes:

[0015] A first driving member, which is arranged on the cabinet body and connected to the flexible steel sheet, and is used to drive the flexible steel sheet to slide within the slide rail;

[0016] A raindrop sensor, which is arranged on the cabinet body and used to detect whether there are raindrops, and is used to control the expansion and contraction of the first driving member.

[0017] By adopting the above technical solution, the raindrop sensor is used to sense whether it is raining. When it is raining, the raindrop sensor causes the first driving member to extend, thereby blocking rainwater from entering the heat dissipation window through the flexible steel sheet; when it is not raining, the first driving member is shortened, thereby enabling the heat dissipation window to have a good heat dissipation effect.

[0018] Further, multiple groups of rollers are arranged at intervals at both ends of the flexible steel sheet and slide within the slide rail.

[0019] By adopting the above technical solution, the flexible steel sheet slides within the slide rail through the rollers, improving the sliding effect of the flexible steel sheet.

[0020] Further, a ventilation mesh plate is arranged on the heat dissipation window, and the ventilation mesh plate is used to block dust or foreign objects entering the heat dissipation window.

[0021] By adopting the above technical solution, the ventilation mesh plate blocks dust or foreign objects from entering the cabinet through the heat dissipation window, reducing the content of dust and sundries in the cabinet.

[0022] Further, a fire prevention component for blocking flames or thick smoke from entering the cabinet through the heat dissipation window is arranged on the cabinet body. The fire prevention component includes:

[0023] An extension rail is provided on the cabinet body and communicates with one end of the arc section away from the vertical section. The flexible steel sheet slides within the extension rail and abuts against the side wall of the cabinet body to seal the heat dissipation window.

[0024] A sliding plate is slidably arranged on the cabinet body along the telescopic direction of the first driving member, and the first driving member is arranged on the sliding plate.

[0025] A second driving member is arranged on the cabinet body and is used to drive the sliding plate to slide.

[0026] A fire detector is arranged on the cabinet body and is used to detect the occurrence of a fire. The fire detector is used to control the telescoping of the second driving member and the first driving member.

[0027] By adopting the above technical solution, when the fire detector detects the occurrence of a fire, the first driving member and the second driving member are started to drive the flexible steel sheet to slide on the slide rail and the extension rail and abut against the cabinet body, so as to seal the heat dissipation window, thereby blocking the flame or thick smoke from entering the interior of the cabinet body and improving the safety of the electrical control cabinet for fire protection.

[0028] Furthermore, a protective cover for rain protection of the first driving member and the vertical section is arranged on the cabinet body, and fireproof layers are arranged on both the protective cover and the flexible steel sheet.

[0029] By adopting the above technical solution, the protective cover prevents rainwater from entering the first driving member and the vertical section, and at the same time, the fireproof layer improves the protection effect of the protective cover and the flexible steel sheet.

[0030] Furthermore, a fireproof sealing block is arranged at the connection of the cabinet body and the extension rail, and the flexible steel sheet abuts against the fireproof sealing block to seal the heat dissipation window.

[0031] By adopting the above technical solution, the flexible steel sheet improves the sealing effect with the cabinet body through the fireproof sealing block.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. The interior of the cabinet body is cooled through the heat dissipation window. When it rains, after the raindrop sensor detects raindrops, the first driving member is started. The first driving member drives the flexible steel sheet to slide within the slide rail, and finally the flexible steel sheet blocks rainwater from entering the heat dissipation window, reducing the probability of rainwater entering the cabinet body. At the same time, after the rain stops, the first driving member drives the flexible steel sheet to move back, ensuring the heat dissipation effect of the heat dissipation window and improving the safety of the electrical control cabinet for fire protection.

[0034] 2. When the fire detector detects a fire, the first driving member and the second driving member are activated to drive the flexible steel sheet to press tightly against the fireproof sealing block, thereby sealing the heat dissipation window, further blocking the entry of flames or thick smoke into the cabinet body, and improving the safety of the electrical control cabinet for fire protection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The following will Figures 1-4 further describe the present application in detail with reference to the attached drawings.

[0041] The embodiment of the present application discloses an intelligent electrical control cabinet for fire protection.

[0042] Embodiment 1

[0043] Referring to Figure 1 and Figure 2 , an intelligent electrical control cabinet for fire protection includes a cabinet body 1, two groups of heat dissipation windows 11 opened on opposite side walls of the cabinet body 1 for ventilation and heat dissipation of the cabinet body 1, and a rain shielding mechanism 2 provided on the cabinet body 1 for blocking rainwater from entering the heat dissipation windows 11.

[0044] Referring to Figure 1 and Figure 2 , the cabinet body 1 has a cuboid structure, the cabinet body 1 is made of a metal material, a fireproof material is coated on the outer surface of the cabinet body 1, a cabinet door for facilitating the opening of the cabinet body 1 is provided at one end of the cabinet body 1, and various switch devices, measuring instruments, protective electrical appliances, auxiliary equipment for fire protection and electrical pipelines connecting them are fixedly installed inside the cabinet body 1.

[0045] Refer to Figure 1 and Figure 2 On opposite side walls of the cabinet body 1, heat dissipation windows 11 for ventilating and dissipating heat from the cabinet body 1 are provided. In order to reduce the probability of external sundries entering the interior of the cabinet body 1 through the heat dissipation windows 11, a ventilation net plate 12 is fixedly installed on the heat dissipation windows 11. The ventilation net plate 12 ensures the ventilation of the heat dissipation windows 11 and also blocks dust or foreign objects entering the heat dissipation windows 11, thereby filtering the air entering the cabinet body 1.

[0046] Refer to Figure 1 and Figure 2 In order to improve the heat dissipation efficiency of the cabinet body 1, a heat dissipation fan 13 is fixedly installed inside the cabinet body 1. The heat dissipation fan 13 speeds up the gas flow rate inside the cabinet body 1, and then exchanges gas with the external gas through the two groups of heat dissipation windows 11, thereby facilitating the reduction of the temperature inside the cabinet body 1 and improving the service life and use safety of the internal components of the cabinet body 1.

[0047] Refer to Figure 2 and Figure 3 On both groups of heat dissipation windows 11, a set of rain shielding mechanisms 2 are provided. The rain shielding mechanism 2 includes slide rails 21, flexible steel sheets 22 and drive components 23. The slide rails 21 are fixedly installed on the outer surface of the cabinet body 1 and are parallel to the sides of the heat dissipation windows 11. There are two groups of slide rails 21, and the two groups of slide rails 21 are respectively located on opposite sides of the heat dissipation windows 11; the slide rails 21 include vertical sections 211 and arc sections 212, and the vertical sections 211 and the arc sections 212 are internally connected. The vertical sections 211 are fixedly installed on the cabinet body 1 and are parallel to the sides of the heat dissipation windows 11, and the vertical sections 211 are located above the heat dissipation windows 11; the arc sections 212 are fixedly installed on the cabinet body 1 and are parallel to the sides of the heat dissipation windows 11, and the gaps between the arc sections 212 and the cabinet body 1 are sealed with fireproof materials.

[0048] Refer to Figure 2 and Figure 3, The flexible steel sheet 22 is slidably installed on the slide rail 21. The two sides of the flexible steel sheet 22 slide within two groups of slide rails 21 respectively. When the flexible steel sheet 22 slides from the vertical section 211 into the arc section 212 and slides within the arc section 212, the flexible steel sheet 22 undergoes elastic deformation along with the arc section 212; when the flexible steel sheet 22 slides to the side of the arc section 212 away from the vertical section 211, the flexible steel sheet 22 shields the outside of the heat dissipation window 11 and blocks rainwater from entering the heat dissipation window 11. At the same time, in order to ensure that the heat dissipation window 11 can also dissipate heat on rainy days, there is a certain distance between the end of the arc section 212 away from the vertical section 211 and the outer surface of the cabinet body 1. When the flexible steel sheet 22 slides to the side of the arc section 212 away from the vertical section 211, the flexible steel sheet 22, the arc section 212, the cabinet body 1, the arc section 212 and the fireproof material between the cabinet body 1 together form a heat dissipation channel 24 for gas to enter or exit the heat dissipation window 11. The opening of the heat dissipation channel 24 is vertically downward, thereby preventing rainwater from flowing into the heat dissipation window 11 through the heat dissipation channel 24.

[0049] Refer to Figure 2 and Figure 3 , The driving assembly 23 is arranged on the cabinet body 1. The driving assembly 23 is used to drive the flexible steel sheet 22 to slide along with the tunnel. The driving assembly 23 includes a first driving member 231 and a rain drop sensor 232. The fixed end of the first driving member 231 is fixedly installed on the cabinet body 1, and the telescopic end of the first driving member 231 is fixedly connected to the flexible steel sheet 22. When the first driving member 231 extends, it pushes the flexible steel sheet 22 to slide from the vertical section 211 to the arc section 212; in this embodiment, the first driving member 231 is any one of an electric telescopic rod or a telescopic cylinder; when the first driving member 231 extends to the maximum value, the front end of the flexible steel sheet 22 slides to the bottom of the arc section 212 to shield the heat dissipation window 11 from rain; when the first driving member 231 contracts to the minimum value, the flexible steel sheet 22 completely enters the vertical section 211, thereby ensuring good heat dissipation performance of the heat dissipation window 11; the rain drop sensor 232 is fixedly installed on the top of the cabinet body 1. The rain drop sensor 232 is used to detect whether there are rain drops. A PLC controller is fixedly installed inside the cabinet body 1. The rain drop sensor 232 is connected to the first driving member 231 through the PLC controller. The rain drop sensor 232 is used to control the telescoping of the first driving member 231; when the rain drop sensor 232 senses rain drops, the rain drop sensor 232 transmits an electrical signal to the PLC controller, and the first driving member 231 is extended through the PLC controller, and the flexible steel sheet 22 is moved to block rainwater from entering the heat dissipation window 11. When the rain drop sensor 232 does not sense rain drops for a long time, the first driving member 231 is shortened through the PLC controller to ensure good heat dissipation effect of the heat dissipation window 11.

[0050] Refer to Figure 2 and Figure 3, To facilitate the sliding of the flexible steel sheet 22 within the sliding rail 21, a sliding groove 213 is provided inside the sliding rail 21. Multiple sets of rollers are installed at intervals on the opposite ends of the flexible steel sheet 22, and the multiple sets of rollers slide within the sliding groove 213, thereby facilitating the sliding of the flexible steel sheet 22 within the sliding rail 21.

[0051] Refer to Figure 1 and Figure 2 , To prevent rain from wetting the first driving member 231 and the vertical section 211, a protective cover 3 is fixedly installed on the cabinet body 1 by bolts. The protective cover 3 is used to block rainwater from entering the first driving member 231 and the vertical section 211, further reducing the probability of rainwater entering the heat dissipation window 11, and at the same time increasing the service life of the first driving member 231.

[0052] Refer to Figure 1 , Fireproof layers are provided on both the protective cover 3 and the flexible steel sheet 22, and the fireproof layers can effectively improve the fireproof effect of the protective cover 3 and the flexible steel sheet 22.

[0053] The working principle of Embodiment 1 of this application is as follows:

[0054] The interior of the cabinet body 1 is cooled through the heat dissipation window 11. When it rains, the rain drop sensor 232 detects raindrops and then activates the first driving member 231. The first driving member 231 drives the flexible steel sheet 22 to slide within the sliding rail 21. Finally, the flexible steel sheet 22 blocks rainwater from entering the heat dissipation window 11, reducing the probability of rainwater entering the cabinet body 1. At the same time, when the rain stops, the first driving member 231 drives the flexible steel sheet 22 to move back, ensuring the heat dissipation effect of the heat dissipation window 11 and improving the safety of the electrical control cabinet for fire protection.

[0055] Embodiment 2

[0056] Refer to Figure 4 , The difference between this embodiment and Embodiment 1 is that a fireproof component 4 for blocking flames or thick smoke from entering the cabinet body 1 through the heat dissipation window 11 is provided on the cabinet body 1. The fireproof component 4 includes an extension rail 41, a sliding plate 42, a second driving member 43, and a fire detector 44. The extension rail 41 is fixedly installed on the cabinet body 1. The extension rail 41 communicates with one end of the arc section 212 away from the vertical section 211. The flexible steel sheet 22 can slide from within the arc section 212 into the extension rail 41 and continue to slide within the extension rail 41. The flexible steel sheet 22 slides within the extension rail 41 and finally abuts against the side wall of the cabinet body 1 to seal the heat dissipation window 11.

[0057] Refer to Figure 4, the sliding plate 42 is slidably mounted on the cabinet body 1. The sliding direction of the sliding plate 42 is parallel to the telescopic direction of the first driving member 231. The first driving member 231 is fixedly mounted on the sliding plate 42 and moves with the sliding plate 42. The second driving member 43 is fixedly mounted on the cabinet body 1 and is used to drive the sliding plate 42 to slide. The second driving member 43 in this embodiment is any one of an electric telescopic rod or a telescopic cylinder. The fire detector 44 is fixedly mounted on the cabinet body 1 and is used to detect the occurrence of a fire. The fire detector 44 is connected to the plc controller, and then the start and stop of the first driving member 231 and the second driving member 43 are controlled through the plc controller. When the fire detector 44 detects the occurrence of a fire, the first driving member 231 is first started through the plc controller to drive the flexible steel sheet 22 to slide to a specified position, and then the second driving member 43 is started to drive the flexible steel sheet 22 to abut against the cabinet body 1, so as to seal the heat dissipation window 11 and thus prevent flames or thick smoke from entering the interior of the cabinet body 1.

[0058] Refer to Figure 4 , a fireproof sealing block 5 is fixedly mounted at the connection between the cabinet body 1 and the extension rail 41. The flexible steel sheet 22 abuts against the side wall of the cabinet body 1 through the fireproof sealing block 5, and seals the heat dissipation window 11 when the flexible steel sheet 22 abuts against the fireproof sealing block 5.

[0059] The working principle of Embodiment 2 of this application is as follows:

[0060] When the fire detector 44 detects the occurrence of a fire, the first driving member 231 and the second driving member 43 are started to drive the flexible steel sheet 22 to abut against the fireproof sealing block 5, so as to seal the heat dissipation window 11 and thus prevent flames or thick smoke from entering the interior of the cabinet body 1, improving the safety of the electrical control cabinet for fire protection.

[0061] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly.
