Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to an electric appliance cabinet device. Background Art

[0002] Power system dispatching automation refers to the use of control systems and telecontrol technologies with electronic computers as the core to achieve automation of power system dispatching. With the continuous development of power technology and the in-depth promotion of smart grid construction, power system dispatching automation devices generally include electrical cabinets and multiple electrical equipment. Each electrical equipment is installed in the electrical cabinet, and each electrical equipment is usually protected by an independent outer cover. The external wires are also usually independently fixed in the electrical cabinet. When disassembling and maintaining, it is necessary to dismantle each outer cover and its external wires separately, which is time-consuming and labor-intensive.

[0003] In addition, traditional power system dispatching automation devices are generally not equipped with fire extinguishing mechanisms or the fire extinguishing mechanisms are set up unreasonably during use. If some equipment lines age or some equipment heats up abnormally and high temperatures or fires occur, it is easy to cause other internal power equipment to be affected, and it is easy to cause the entire power system dispatching automation device to lose control, and it is impossible to cool down, extinguish the fire, and alarm in time to eliminate the danger, causing great economic losses. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an electrical cabinet device which is convenient for disassembly, replacement and maintenance of internal electrical equipment and saves time and effort.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: An electrical cabinet device comprises an electrical cabinet, a plurality of electrical equipment, two protective covers with openings facing each other, and a wire clamping mechanism for clamping electric wires. The two protective covers are arranged relatively in the electrical cabinet and can be relatively close to or far away from each other to achieve opening and closing. Each of the electrical equipment is installed in the electrical cabinet and is located between the two protective covers. The wire clamping mechanism is arranged on the electrical cabinet. A driving mechanism and a linkage mechanism are also arranged in the electrical cabinet. The driving mechanism is used to drive the opening and closing movements of the two protective covers. The linkage mechanism connects the wire clamping mechanism and the driving mechanism and is used to make the wire clamping mechanism clamp when the two protective covers are combined and release when the two protective covers are opened.

[0006] As a further improvement of the above technical solution: The driving mechanism includes a driving component and a double-headed screw with opposite spiral directions at both ends. The double-headed screw is rotatably set on the electrical cabinet. The two protective covers are threadedly connected to the two ends of the double-headed screw respectively. The driving component is set on the electrical cabinet and connected to the double-headed screw. The linkage mechanism connects the wire clamping mechanism and the double-headed screw.

[0007] The wire clamping mechanism comprises a first wire clamping seat and a second wire clamping seat. The first wire clamping seat and the second wire clamping seat can be arranged on the electrical cabinet relatively close to or far away from each other and are connected to the linkage mechanism for clamping the discharge wire.

[0008] The first wire clamping seat is fixedly arranged on the electrical cabinet, and the second wire clamping seat is movably arranged on the electrical cabinet. The linkage mechanism includes a rack, a gear, a transmission shaft and a linkage assembly. The rack is fixed on the second wire clamping seat, and the transmission shaft is rotatably arranged on the electrical cabinet. The gear is arranged on the transmission shaft and meshes with the rack. The linkage assembly connects the transmission shaft and the stud screw.

[0009] A first clamping block is slidably provided on the first clamping seat, a second clamping block is provided on the second clamping seat, a row of clamping grooves are provided on the first clamping block and the second clamping block, the clamping grooves on the first clamping block are arranged in one-to-one correspondence with the clamping grooves on the second clamping block, and an elastic component is provided between the second clamping block and the second clamping seat.

[0010] The linkage assembly is a pulley assembly.

[0011] An exhaust port is provided on the outer wall of the protective cover, an exhaust component is provided outside the exhaust port of the protective cover, a removable filter is provided between the exhaust component and the exhaust port, and a locking assembly is provided on the protective cover, the locking assembly is used to lock the filter and abut against the inner wall of the electrical cabinet when the two protective covers are opened to unlock the filter.

[0012] The locking assembly includes a locking rod and an elastic member. The middle part of the locking rod is rotatably arranged on the protective cover. The elastic member is arranged between the locking rod and the protective cover, so that one end of the locking rod is tilted outward and the other end is clamped in the bayonet on the filter screen.

[0013] The electrical cabinet is provided with a plurality of support platforms spaced apart from each other in an upper and lower manner between two protective covers, each of the electrical equipment is respectively arranged on each support platform, and each of the electrical equipment is covered with a cover body.

[0014] A temperature sensor is provided under each of the cover bodies, and a plurality of electric-controlled fire extinguishers are provided in the electrical cabinet. Each of the electric-controlled fire extinguishers is arranged in a one-to-one correspondence with each electrical device. The electrical cabinet device also includes a control module, and the drive mechanism, temperature sensor and electric-controlled fire extinguisher are all electrically connected to the control module.

[0015] Compared with the prior art, the advantages of the present invention are: In the electrical cabinet device of the present invention, when it is disassembled and maintained, the driving mechanism drives the two protective covers to open, so that each electrical device is exposed, which is convenient for disassembly and maintenance. At the same time, when the two protective covers are opened, the driving mechanism drives the wire clamping mechanism to loosen the external wires of each electrical device through the linkage mechanism. In this way, on the one hand, the two protective covers can be opened to expose each electrical device, which saves time and effort compared to disassembling them individually; on the other hand, when the two protective covers are opened, the wire clamping mechanism is loosened at the same time, avoiding the fixed action of removing the external wires, and opening and loosening are performed simultaneously, which further saves time and effort. Conversely, the driving mechanism drives the two protective covers to close and cover the outside of each electrical device; at the same time, the driving mechanism drives the wire clamping mechanism to clamp the external wires of each electrical device through the linkage mechanism. The electrical cabinet device is convenient for the disassembly and maintenance of internal electrical equipment, and saves time and effort.

[0016] In the electric cabinet device of the present invention, when the two protective covers are opened, the end of the locking rod that tilts outwards abuts against the inner wall of the electric cabinet, so that the other end moves out of the bayonet on the filter, thereby releasing the locking and limiting effect on the filter, and the filter can be pulled out. Conversely, when the two protective covers are closed, the end of the locking rod that tilts outwards is separated from the inner wall of the electric cabinet, and the locking rod is restored to tilt outwards at one end and is clamped in the bayonet on the filter under the elastic force recovery effect of the elastic member. In this way, the locking and unlocking process of the filter is automatically performed without manual operation, and is easy to use.

[0017] In the electrical cabinet device of the present invention, when the two protective covers are opened, the locking assembly abuts against the inner wall of the electrical cabinet to release the lock on the filter, and the filter can be pulled out. Conversely, when the two protective covers are closed, the locking assembly is separated from the inner wall of the electrical cabinet, and the locking assembly resumes the locking function on the filter. In this way, the locking and unlocking process of the filter is automatically performed without manual operation, and it is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Figures 1 to 8 An embodiment of an electrical cabinet device of the present invention is shown. The electrical cabinet device of this embodiment includes an electrical cabinet 1, a plurality of electrical devices 2, two protective covers 3 with openings facing each other, and a clamping mechanism 4 for clamping the discharge wire. The two protective covers 3 are relatively arranged in the electrical cabinet 1 and can be relatively close to or away from each other to achieve opening and closing. Each electrical device 2 is respectively installed in the electrical cabinet 1 and is located between the two protective covers 3. The clamping mechanism 4 is arranged on the electrical cabinet 1. A driving mechanism 5 and a linkage mechanism 6 are also arranged in the electrical cabinet 1. The driving mechanism 5 is used to drive the opening and closing of the two protective covers 3. The linkage mechanism 6 connects the clamping mechanism 4 and the driving mechanism 5, and is used to make the clamping mechanism 4 clamp when the two protective covers 3 are combined and loose when they are opened. The two protective covers 3 are closed and cover the outside of each electrical device 2 to play a protective role.

[0032] During replacement and maintenance, the driving mechanism 5 drives the two protective covers 3 to open, so that each electrical device 2 is exposed, which is convenient for replacement and maintenance. At the same time, when the two protective covers 3 are opened, the driving mechanism 5 drives the clamping mechanism 4 to loosen the external wires of each electrical device 2 through the linkage mechanism 6. In this way, on the one hand, the two protective covers 3 can be opened to expose each electrical device 2, which saves time and effort compared to disassembling them individually; on the other hand, when the two protective covers 3 are opened, the clamping mechanism 4 is loosened at the same time, avoiding the fixed action of removing the external wires, and opening and loosening are carried out simultaneously, further saving time and effort. On the contrary, the driving mechanism 5 drives the two protective covers 3 to close and cover the outside of each electrical device 2; at the same time, the driving mechanism 5 drives the clamping mechanism 4 to clamp the external wires of each electrical device 2 through the linkage mechanism 6. This electrical cabinet device is convenient for the replacement and maintenance of the internal electrical equipment 2, and saves time and effort.

[0033] Furthermore, if Figure 1 and Figure 7As shown, in this embodiment, the driving mechanism 5 includes a driving component 51 and a stud screw 52 with opposite spiral directions at both ends. The stud screw 52 is rotatably arranged on the electrical cabinet 1. The two protective covers 3 are respectively threadedly connected to the two ends of the stud screw 52. The driving component 51 is arranged on the electrical cabinet 1 and connected to the stud screw 52. The linkage mechanism 6 connects the clamping mechanism 4 and the stud screw 52. The driving component 51 is used to drive the stud screw 52 to rotate forward and reverse. When the driving component 51 drives the stud screw 52 to reverse, it drives the stud screw 52 to reverse. The stud screw 52 drives the two protective covers 3 to move relatively away from each other through the pushing effect of the threaded connection to open. At the same time, the stud screw 52 drives the clamping mechanism 4 to loosen through the linkage mechanism 6 to release the clamping effect on the external wires of each electrical device 2. When the driving component 51 drives the stud screw 52 to rotate forward, the stud screw 52 is driven to rotate forward. The stud screw 52 drives the two protective covers 3 to move relatively close to each other to close through the pushing action of the threaded connection, so as to cover the outside of each electrical device 2. At the same time, the stud screw 52 drives the wire clamping mechanism 4 to clamp through the linkage mechanism 6 to clamp the external wires of each electrical device 2.

[0034] Furthermore, if Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the clamping mechanism 4 includes a first clamping seat 41 and a second clamping seat 42, which can be arranged on the electrical cabinet 1 relatively close to and far from each other, and connected to the linkage mechanism 6, for clamping the discharge wire. Specifically, the first clamping seat 41 and the second clamping seat 42 are arranged horizontally and move vertically relative to each other. Preferably, the first clamping seat 41 and the second clamping seat 42 are arranged above the two protective covers 3.

[0035] Furthermore, if Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the first wire clamping seat 41 is fixedly arranged on the electrical cabinet 1, the second wire clamping seat 42 is movably arranged on the electrical cabinet 1, and the linkage mechanism 6 includes a rack 61, a gear 62, a transmission shaft 63 and a linkage assembly 64. The rack 61 is fixed on the second wire clamping seat 42, the transmission shaft 63 is rotatably arranged on the electrical cabinet 1, the gear 62 is arranged on the transmission shaft 63 and meshes with the rack 61, and the linkage assembly 64 connects the transmission shaft 63 and the stud screw 52.

[0036] When the driving component 51 drives the stud screw 52 to reverse, it also drives the stud screw 52 to reverse, and the stud screw 52 drives the two protective covers 3 to move relatively apart to open through the pushing action of the threaded connection. At the same time, the stud screw 52 drives the transmission shaft 63 to rotate through the linkage assembly 64, and the gear 62 rotates synchronously with the transmission shaft 63, and drives the rack 61 and the second wire clamping seat 42 to move relatively away from the first wire clamping seat 41, so as to release the clamping effect of the first wire clamping seat 41 and the second wire clamping seat 42 on the external wires of each electrical device 2. When the driving component 51 drives the stud screw 52 to rotate forward, the stud screw 52 is driven to rotate forward, and the stud screw 52 drives the two protective covers 3 to be relatively close to each other through the pushing effect of the threaded connection, so as to cover the outside of each electrical device 2. At the same time, the stud screw 52 drives the transmission shaft 63 to rotate through the linkage component 64, and the gear 62 rotates synchronously with the transmission shaft 63, and drives the rack 61 and the second clamping seat 42 to be relatively close to the first clamping seat 41, so that the first clamping seat 41 and the second clamping seat 42 clamp the external wires of each electrical device 2. Preferably, the second clamping seat 42 is arranged above the first clamping seat 41. The linkage mechanism 6 allows the wires of each electrical device 2 to be automatically released from the limit when the two protective covers 3 are opened during the subsequent maintenance of the electrical device 2, so that the maintenance is convenient.

[0037] Furthermore, if Figure 8 As shown, in this embodiment, a first clamping block 411 is slidably provided on the first clamping seat 41, and a second clamping block 421 is provided on the second clamping seat 42. A row of clamping grooves 44 are provided on the first clamping block 411 and the second clamping block 421. The clamping grooves 44 on the first clamping block 411 and the clamping grooves 44 on the second clamping block 421 are arranged one by one, and an elastic component 43 is provided between the second clamping block 421 and the second clamping seat 42.

[0038] An elastic component 43 is provided between the second clamping block 421 and the second clamping seat 42, which can not only ensure the clamping effect of the first clamping block 411 and the second clamping block 421 on the wire, but also help prevent the wire from being damaged. The wire is clamped by the relative clamping groove 44, the contact is tight, and it is not easy to loosen. When the first clamping block 411 and the second clamping block 421 clamp the wire, the elastic component 43 (with elastic restoring force) will be squeezed synchronously, and the elastic component 43 will be deformed after being squeezed. At this time, the elastic component 43 is compressed, and its own elastic potential energy increases. The elastic force of the elastic component 43 is applied to the second clamping block 421 and the second clamping seat 42, ensuring that there is pressure between the second clamping block 421 and the second clamping seat 42, and it maintains positive pressure after clamping the wire, thereby improving the clamping effect of the wire. Preferably, the elastic component 43 is an arc-shaped steel plate. More preferably, a vertical guide rail is provided on the electrical cabinet 1, and the second clamping seat 42 is slidably arranged on the vertical guide rail.

[0039] Furthermore, if Figure 7As shown, in this embodiment, the linkage assembly 64 is a pulley assembly. Specifically, a threaded sleeve is provided at the bottom of the protective cover 3, which is threadedly connected to the stud screw 52 through the threaded sleeve. In this way, the stud screw 52 is far away from the transmission shaft 63, and the pulley assembly is used to facilitate long-distance transmission. In order to facilitate the location arrangement, the pulley assembly may include a plurality of belt combination transmissions.

[0040] Furthermore, if Figure 4 As shown, in this embodiment, an exhaust port is provided on the outer wall of the protective cover 3, and an exhaust component 31 is provided outside the exhaust port of the protective cover 3. A removable filter 32 is provided between the exhaust component 31 and the exhaust port. A locking assembly 33 is provided on the protective cover 3. The locking assembly 33 is used to lock the filter 32 and abut against the inner wall of the electrical cabinet 1 when the two protective covers 3 are opened to release the lock of the filter 32. The exhaust component 31 is used to accelerate the exhaust of air inside the protective cover 3 to facilitate heat dissipation, such as a heat dissipation fan. The filter 32 filters dust and impurities in the air during the heat dissipation process. The filter 32 is designed to be removable and locked by the locking assembly 33, which is convenient for disassembly and assembly, and easy to replace and maintain.

[0041] When the two protective covers 3 are opened, the locking assembly 33 abuts against the inner wall of the electrical cabinet 1 to release the lock on the filter 32, and the filter 32 can be pulled out. Conversely, when the two protective covers 3 are closed, the locking assembly 33 is separated from the inner wall of the electrical cabinet 1, and the locking assembly 33 resumes the locking function on the filter 32. In this way, the locking and unlocking process of the filter 32 is automatically performed without manual operation, which is convenient to use.

[0042] Furthermore, if Figure 4 As shown, in this embodiment, the locking assembly 33 includes a locking rod 331 and an elastic member 332. The middle part of the locking rod 331 is rotatably set on the protective cover 3, and the elastic member 332 is set between the locking rod 331 and the protective cover 3, so that one end of the locking rod 331 is tilted outward and the other end is clamped in the bayonet 321 on the filter net 32.

[0043] When the two protective covers 3 are opened, the end of the locking rod 331 that tilts outwards abuts against the inner wall of the electrical cabinet 1, so that the other end moves out of the bayonet 321 on the filter 32, thereby releasing the locking and limiting effect on the filter 32, and the filter 32 can be pulled out. Conversely, when the two protective covers 3 are closed, the end of the locking rod 331 that tilts outwards is separated from the inner wall of the electrical cabinet 1, and the locking rod 331 is restored to tilt outwards at one end and stuck in the bayonet 321 on the filter 32 at the other end under the elastic force of the elastic member 332.

[0044] Furthermore, in this embodiment, the electrical cabinet 1 is provided with a plurality of support platforms 11 spaced apart from each other in the upper and lower directions between the two protective covers 3, and each electrical device 2 is respectively provided on each support platform 11, and each electrical device 2 is covered with a cover body 21. Each electrical device 2 is independently installed on the corresponding support platform 11, forming a modular installation, and the two protective covers 3 are convenient to open and close, and each electrical device 2 is easy to inspect, maintain and upgrade, thereby ensuring the stability of the device, and convenient for updating and upgrading, and subsequent inspection and maintenance.

[0045] Furthermore, if Figure 6 As shown, in this embodiment, a temperature sensor 8 is provided under each cover 21, and a plurality of electric-controlled fire extinguishers 9 are provided in the electrical cabinet 1. Each electric-controlled fire extinguisher 9 is arranged one-to-one with each electrical device 2. The electrical cabinet device also includes a control module, and the drive mechanism 5, the temperature sensor 8 and the electric-controlled fire extinguisher 9 are all electrically connected to the control module. Each temperature sensor 8 respectively monitors the temperature of the space under the cover 21 where each electrical device 2 is located in real time. When the temperature of the space under the cover 21 where a certain electrical device 2 is located exceeds a set threshold, a signal is transmitted to the control module, and the control module starts the drive mechanism 5, drives the two protective covers 3 to open relatively far away, and starts the electric-controlled fire extinguisher 9 corresponding to the electrical device 2, and uses the corresponding electric-controlled fire extinguisher 9 to quickly cool down and extinguish the fire, so as to prevent the high temperature and the fire source from spreading to other electrical devices 2 and reduce losses.

[0046] Furthermore, in this embodiment, an alarm can be provided on the electrical cabinet 1, and the alarm is electrically connected to the control module. Each temperature sensor 8 monitors the temperature of the space below the cover 21 where each electrical device 2 is located in real time. When the temperature of the space below the cover 21 where a certain electrical device 2 is located exceeds a set threshold, a signal is transmitted to the control module, and the control module causes the alarm to sound an alarm in time.

[0047] Furthermore, in this embodiment, the electrical cabinet 1 is provided with a horizontal guide rail, and the two protective covers 3 are slidably arranged on the horizontal guide rail to achieve horizontal opening and closing. An avoidance groove is provided at the place where the protective cover 3 interferes with the movement inside the electrical cabinet 1.
