Description

Technical Field

[0001] This utility model relates to the field of power distribution devices, and in particular to an openable protective power distribution device. Background Technology

[0002] A power distribution unit, also known as a distribution box, is a device used to receive and distribute electrical energy normally during operation. In case of a fault, it can quickly disconnect the faulty part and restore normal operation through automatic or manual operation. It mainly uses an outer shell to form a cabinet or box structure, and installs power distribution components inside.

[0003] As a key device for power distribution and control, power distribution equipment is widely used in industrial, commercial and residential fields. In traditional technology, power distribution equipment uses a simple latch to lock the door panel and the outer casing. The locking function is limited. During maintenance, maintenance personnel need to open the door panel to operate. After completing the maintenance work, maintenance personnel often forget to close the door panel, which poses a risk of abnormal operation. The power distribution protection effect is poor, the reliability of power distribution is low and the safety is poor. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes an opening-protection type power distribution device that can ensure the effective closure of the door panel, has good power distribution protection effect, and ensures safe and reliable power distribution.

[0005] An opening-protection type power distribution device according to an embodiment of the present utility model includes:

[0006] The outer casing has a door frame;

[0007] The door panel is connected to the outer shell. The door panel is rotatably connected to the first rotating shaft. A positioning block and a buckle for locking the door frame are provided on one side of the first rotating shaft. Two limiting blocks are provided on the side of the door panel near the outer shell. The two limiting blocks are located at the two ends of the movement path of the positioning block, so that the central angle of the rotation path of the buckle is an acute angle pointing horizontally upward. An iron core is provided on the side of the door panel near the outer shell.

[0008] The monitoring component includes a sleeve, a positioning element, a trigger switch, a second rotating shaft, and an elastic element. The sleeve, positioning element, and trigger switch are all connected to the outer casing. An electromagnetic coil is wound around the outside of the sleeve, which is used to insert an iron core. The second rotating shaft is rotatably connected to the outer casing and is connected to a magnetic linkage plate and a trigger plate. The magnetic linkage plate is located on the side of the sleeve away from the door panel. The elastic element connects the magnetic linkage plate and the positioning element so that the magnetic linkage plate tends to move away from the sleeve. The trigger plate is located on one side of the trigger switch, and the trigger switch is connected to an opening prompt module.

[0009] In this embodiment, both the second rotating shaft and the trigger plate are non-magnetic structures.

[0010] In this embodiment, the trigger switch is also connected to a lighting module.

[0011] In this embodiment, the end face of the first rotating shaft away from the outer casing is located on the surface of the door panel away from the outer casing, and a lock hole is provided on the end face of the first rotating shaft away from the outer casing.

[0012] In this embodiment, a counterweight is provided at the bottom of the buckle.

[0013] In this embodiment, the side of the door panel closest to the door frame is provided with a positioning groove that matches the door frame.

[0014] In this embodiment, the side of the outer casing is provided with heat dissipation holes, and a protective plate connected to the outer casing is provided on the outside of the heat dissipation holes.

[0015] In this embodiment, a filter connected to the outer casing is provided on the inner side of the heat dissipation hole.

[0016] The embodiments of this utility model have at least the following beneficial effects:

[0017] Through the coordinated action of the latch and positioning block connected to the first rotating shaft, gravity keeps the latch horizontal. When the door panel is closed and pushed, the latch automatically engages with the door frame, thus locking the door. The locking effect is stable and reliable, preventing accidental opening. Furthermore, the two limiting blocks effectively restrict the latch's rotation path upwards from the horizontal plane. Setting the central angle of the corresponding rotation path to an acute angle effectively improves the reliability of the latch's automatic rotation and falling action, further enhancing the locking effect. When the door panel closes, the electromagnetic coil and iron core form an electromagnet, creating a magnetic attraction to the magnetic linkage plate. This causes the magnetic linkage plate to overcome the elastic force of the elastic element and rotate along with the first rotating shaft and the trigger plate. The trigger plate activates the opening prompt module, generating audible or visual prompts. This not only ensures effective door closure but also alerts surrounding personnel, reducing the probability of abnormal operation. Real-time monitoring ensures the overall structure's power distribution protection performance, guaranteeing safe and reliable power distribution. The linkage design between the trigger plate and the trigger switch is compatible with various communication or alarm modules, offering strong scalability and wide application. Furthermore, the electromagnetic coil loses its magnetic attraction when separated from the iron core, preventing the iron core from attracting other magnetic materials that could affect the opening and closing action. This reduces mechanical wear, ensuring high reliability of the door's opening and closing action and a long service life for the overall structure. Attached Figure Description

[0035] A power distribution unit, also known as a distribution box, is a device used to receive and distribute electrical energy normally during operation. In case of a fault, it can quickly disconnect the faulty part and restore normal operation through automatic or manual operation. It mainly uses an outer shell to form a cabinet or box structure, and installs power distribution components inside.

[0036] As a key device for power distribution and control, power distribution equipment is widely used in industrial, commercial and residential fields. In traditional technology, power distribution equipment uses a simple latch to lock the door panel and the outer casing. The locking function is limited. During maintenance, maintenance personnel need to open the door panel to operate. After completing long-term or high-intensity maintenance work, maintenance personnel often forget to close the door panel, which poses a risk of abnormal operation. The power distribution protection effect is poor, the reliability of power distribution is low, and the safety is poor.

[0037] The following is for reference only. Figure 1 To be continued Figure 8 This invention describes an opening-protection type power distribution device that can ensure effective closure of the door panel, provides good power distribution protection, and ensures safe and reliable power distribution.

[0038] Reference Figures 1 to 8 An embodiment of the present invention provides an openable protective power distribution device, comprising:

[0039] The housing 100 has a door frame 110 surrounding the opening of the housing 100, and the housing 100 is used to install power distribution components;

[0040] A door panel 200 is movably connected to the outer casing 100. One side of the door panel 200 is hinged to an opening in the outer casing 100. The door panel 200 is used to close the opening in the outer casing 100. The door panel 200 is rotatably connected to a first rotating shaft 210 parallel to the horizontal plane. One side of the first rotating shaft 210 is provided with a positioning block 211 and a latch 212 for locking and connecting to the door frame 110. The latch 212 and the positioning block 211 are connected to the circumferential surface of the outer casing 100, and the latch 212 and the positioning block... Both 211 are located on the side of the door panel 200 near the outer shell 100. When locked and closed, the latch 212 engages with the door frame 110 to lock the position between the door panel 200 and the outer shell 100. Two limiting blocks 220 are provided on the side of the door panel 200 near the outer shell 100. The two limiting blocks 220 are located at opposite ends of the movement path of the positioning block 211, so that the central angle corresponding to the rotation path of the latch 212 is an acute angle swinging upwards horizontally, i.e., the central angle... One side is located in the horizontal plane, and the other side of the central angle is located above the horizontal plane. When the buckle 212 is at the lowest point, the line connecting the center of the buckle 212 and the first rotating shaft 210 is parallel to the horizontal plane. When the buckle 212 moves to the highest point, the angle between the line connecting the center of the buckle 212 and the first rotating shaft 210 and the horizontal plane is an acute angle. This can effectively control the buckle 212 to be in a horizontal position under gravity alone, thereby ensuring the stability of the structure when the buckle 212 is locked and connected to the door frame 110. The guide slope of the buckle 212 is set away from the first rotating shaft 210, and the side of the buckle 212 near the first rotating shaft 210 is provided with a deformation relief groove. This can ensure that the buckle 212 can deform and make relief when the guide slope contacts the door frame 110, so that the buckle 212 can be locked and fastened to one side of the door frame 110. The self-locking performance is reliable. The side of the door panel 200 near the outer shell 100 is provided with an iron core 230.

[0041] The monitoring component 300 is activated, comprising a sleeve 310, a positioning element 320, a trigger switch 330, a second rotating shaft 340, and an elastic element 350. The sleeve 310, positioning element 320, and trigger switch 330 are all connected to the housing 100. An electromagnetic coil 311 is wound around the outside of the sleeve 310. The sleeve 310 is used to insert an iron core 230. When the iron core 230 is inserted into the sleeve 310, under the action of the electromagnetic coil 311, the iron core 230 and the electromagnetic coil 311 form a running electromagnet. It generates a strong magnetic force. The second rotating shaft 340 is rotatably connected to the outer casing 100. The second rotating shaft 340 is perpendicular to the horizontal plane. Magnetic linkage plate 341 and trigger plate 342 are respectively connected to opposite sides of the second rotating shaft 340. Magnetic linkage plate 341 and trigger plate 342 can rotate with the second rotating shaft 340 around an axis perpendicular to the horizontal plane. Magnetic linkage plate 341 is located on the side of sleeve 310 away from door panel 200. The two ends of elastic element 350 are respectively connected to magnetic linkage plate 341 and positioning element 342. Preferably, the elastic element 350 is a tension spring, which causes the magnetic linkage plate 341 to move away from the sleeve 310. The elastic force of the elastic element 350 is greater than the magnetic attraction force of the electromagnetic coil 311. Before the iron core 230 is inserted into the sleeve 310, the positioning effect of the elastic element 350 on the magnetic linkage plate 341 can be effectively ensured. The magnetic linkage plate 341 can be one of iron plate, cobalt plate or nickel plate. When the iron core 230 is inserted into the running electromagnetic coil 311, the electromagnet formed by the iron core 230 and the electromagnetic coil 311 generates a magnetic attraction force greater than the elastic force. The magnetic linkage plate 341 is attracted and moves by the electromagnet. The first rotating shaft 210 rotates and drives the trigger plate 342 to rotate synchronously. The trigger plate 342 is located on one side of the trigger switch 330. The trigger plate 342 is used to control the trigger switch 330. The trigger switch 330 is electrically connected to the opening prompt module 331. The opening prompt module 331 is used to generate opening prompt information, such as alarm sound effect, alarm light effect, etc.

[0042] State reference when closed Figures 1 to 3 As shown, the state reference when it is turned on. Figures 4 to 8 As shown.

[0043] Through the coordinated action of the latch 212 connected to the first rotating shaft 210 and the positioning block 211, gravity keeps the latch 212 horizontal. When the door panel 200 is closed and pushed, the latch 212 automatically engages with the door frame 110, thus locking. The locking effect is stable and reliable, preventing accidental opening. Furthermore, in conjunction with the two limiting blocks 220, the rotation path of the latch 212 is effectively restricted from rotating upwards from the horizontal plane. The central angle of the corresponding rotation path is set to an acute angle, which effectively improves the reliability of the automatic rotation and falling action of the latch 212. After automatically falling, the horizontally positioned latch 212... This provides a basis for automatic locking and positioning, and can further improve the reliability of the locking effect. When the door panel 200 is closed, the electromagnetic coil 311 and the iron core 230 form an electromagnet that can magnetically attract the magnetic linkage plate 341. This causes the magnetic linkage plate 341 to overcome the elastic force of the elastic element 350 and rotate together with the first rotating shaft 210 and the trigger plate 342. The trigger plate 342 triggers the opening prompt module 331 to generate opening prompt information such as sound or light effects that can be recognized by humans. This not only continuously reminds maintenance personnel that the door panel 200 is in the open state, but also reduces the risk of accidents. The system minimizes the probability of door panel 200 failing to close due to negligence after maintenance, ensuring its effective closure. The generated opening alert also alerts nearby personnel, effectively reducing the likelihood of abnormal operations such as unreported or unauthorized opening. Real-time monitoring ensures the overall structure's power distribution protection performance, guaranteeing safe and reliable power distribution. The linkage design between trigger board 342 and trigger switch 330 is compatible with various communication or alarm modules, offering strong scalability and wide applicability. Furthermore, the magnetic attraction of the magnetic linkage plate 341 is achieved through the combination of the electromagnetic coil 311 and the iron core 230. When the electromagnetic coil 311 separates from the iron core 230, the iron core 230 loses its magnetic attraction as it follows the door panel 200 to the outside of the outer shell 100. This prevents the iron core 230 from attracting other magnetic materials and affecting the opening and closing action. Especially in industrial environments with a lot of dust, the iron core 230, detached from the electromagnetic coil 311, is less likely to attract iron filings or metal particles, which can reduce mechanical wear. The opening and closing action of the door panel 200 is highly reliable, and the overall structure has a long service life.

[0044] It is understandable that both the second rotating shaft 340 and the trigger plate 342 are non-magnetic structures. Non-magnetic materials can be such as aluminum alloy, engineering plastics or stainless steel. The non-magnetic structure ensures that the second rotating shaft 340 has no additional magnetic resistance during rotation, thereby improving the sensitivity and smoothness of the opening monitoring component 300.

[0045] Non-magnetic materials do not easily attract iron filings or metal particles, reducing mechanical wear and making them particularly suitable for dusty industrial environments, thus extending service life. The separate design of the trigger plate 342 and the magnetic linkage plate 341 satisfies the electromagnetic triggering function requirements while avoiding the lag problem caused by overall magnetization. Preferably, the elastic element 350 is a non-magnetic tension spring.

[0046] It is understandable that the trigger switch 330 is also electrically connected to the lighting module 332, which can be an LED light. When the door panel 200 is opened, the trigger switch 330 controls the lighting module 332 to be activated, thereby creating a supplementary lighting effect for the interior of the outer casing 100. This facilitates maintenance operations and avoids misoperation or safety hazards caused by insufficient light.

[0047] It should be noted that the opening prompt module 331 includes a control circuit and an alarm. The controlled end of the control circuit is electrically connected to the trigger switch 330, and the control end of the control circuit is electrically connected to the alarm. The control circuit can employ any existing delay circuit or other control circuit. Depending on different control requirements, the control circuit can be configured with different circuit structures to meet different functional needs. When the control circuit is a delay circuit, when the door panel 200 is opened, the trigger switch 330 sends a trigger signal to the delay circuit. After receiving the trigger signal, the delay circuit starts timing. After a preset time, the delay circuit sends an alarm signal to the alarm. Upon receiving the alarm signal, the alarm generates an opening prompt message that can be recognized by humans, usually an audible and visual message. When the door panel 200 is closed, the trigger signal sends a stop signal and controls the alarm to stop working through the delay circuit, thereby dispelling the opening abnormality alarm. The alarm can be a buzzer, an indicator light, or a speaker with a storage unit.

[0048] It is understood that the end face of the first rotating shaft 210 away from the outer casing 100 is located on the surface of the door panel 200 away from the outer casing 100, and the end face of the first rotating shaft 210 away from the outer casing 100 is provided with a lock hole 213. The lock hole 213 can be a special shape such as a six-star or a plum blossom shape. The lock hole 213 is used to adapt to the shape of a special key. After the special key is inserted into the lock hole 213, rotation can drive the first rotating shaft 210 to rotate, thereby driving the latch 212 to rotate along the rotation path. When the latch 212 rotates to the highest point, it disengages from the door frame 110 to unlock. Due to the unilateral guiding deformation characteristic of the latch 212, the locking action does not require the use of a special key.

[0049] It is understandable that a counterweight 214 is provided at the bottom of the latch 212. When the first rotating shaft 210 rotates to the point where the line connecting the positioning block 211 and the first rotating shaft 210 is horizontal, the counterweight 214 is located at the bottom of the latch 212, enhancing the gravity self-locking effect and preventing the latch 212 from accidentally disengaging due to vibration or wind, thereby improving the reliability of the locked state. When the first rotating shaft 210 rotates to the point where the line connecting the positioning block 211 and the first rotating shaft 210 forms an angle with the horizontal plane, the counterweight 214 is located on the side of the latch 212 closest to the edge of the door panel 200, which is the bottom surface. This effectively improves the reliability of the latch 212's rotation and falling action, thereby effectively ensuring the automatic locking function.

[0050] Understandably, the door panel 200 has a positioning groove 240 on the side near the door frame 110 that matches the door frame 110. The positioning groove 240 is used to accommodate the door frame 110, which can effectively improve the stability of the relative position between the door panel 200 and the outer shell 100 when locked. In addition, the buckle 212 is hidden inside the door panel 200, avoiding direct exposure at the edge of the door panel 200, which can effectively improve the anti-pry security performance.

[0051] Specifically, the positioning groove 240 is equipped with an anti-collision strip, which can be a silicone strip or a rubber strip. The anti-collision strip can effectively reduce the impact force between the door frame 110 and the door panel 200 during a collision, which can not only effectively reduce the noise generated when closing, but also effectively reduce collision wear, thereby effectively extending the service life.

[0052] It is understood that the outer casing 100 has multiple sets of heat dissipation holes 120 on its side, and a protective plate 130 connected to the outer casing 100 is provided on the outside of the heat dissipation holes 120. The protective plate 130 is located on the outside of the outer casing 100 and covers the top of the heat dissipation holes 120. Preferably, the protective plate 130 is inclined to prevent rainwater from directly hitting it, ensuring heat dissipation efficiency while meeting the requirements for moisture protection.

[0053] It is understandable that a filter 140 connected to the housing 100 is provided on the inner side of the heat dissipation hole 120. The filter 140 is located inside the housing 100 and can be a filter structure such as a metal filter screen. It can achieve the effects of dust prevention and insect prevention, and can be disassembled for cleaning and maintenance.

[0054] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
