Description

Technical Field

[0001] This utility model belongs to the technical field of mining electrical equipment, and specifically refers to a mining switch cabinet with lighting function. Background Technology

[0002] Mining switchgear is an important electrical equipment in mine production. It is mainly used for power distribution, circuit control and equipment protection in underground power supply systems. It provides stable power support for various underground operating equipment such as tunneling machines and conveyors, while ensuring the safe operation of circuits. Its performance is directly related to the continuity and safety of mine production.

[0003] However, traditional mine switchgear generally lacks dedicated lighting functions. During underground maintenance or operation, workers need to use handheld flashlights or other lighting tools, which not only occupies their hands and affects work efficiency but also increases the risk of misoperation due to insufficient light. The few mine switchgear units that do have lighting functions either only turn off the power when the cabinet door is closed and turn on when it is open, making it impossible to manually turn off the lights when the cabinet door is open, easily leading to energy waste; or they rely on complex electronic sensing devices, which are difficult to adapt to the harsh, humid, and dusty environment of mines and lack the convenience of automatically turning on the lights when the door is opened, failing to meet actual operational needs. Utility Model Content

[0004] This utility model uses an internal cabinet light, a switch base with a reset button, and a mechanical trigger mechanism for the cabinet door to enable the light to turn on when the door is opened and to be manually turned off when the door is open, thereby alleviating the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a mine switch cabinet with lighting function includes a cabinet body, a cabinet door hinged to the cabinet body, and further includes: The lighting assembly includes a lighting body installed on the top surface of the cabinet and a lighting switch holder with a reset button, the reset button being electrically connected to the lighting body; The mechanical triggering mechanism includes a mounting base fixed to the inside of the cabinet door, a flexible strip with its fixed end on the mounting base, and a trigger plate on the free end of the flexible strip. The trigger plate can be separated from the lighting switch base by a magnetic connector and presses against the reset button to cut off the power to the lighting body. When the cabinet door is opened, the trigger plate is pulled away from the reset button by the flexible strip, which powers the lighting body.

[0006] The present invention is further configured such that the flexible strip is a metal braided flexible hose.

[0007] The present invention is further configured such that the magnetic connector includes a permanent magnet disposed on the trigger plate and a magnetic conductor disposed on the lighting switch base.

[0008] The present invention is further provided with a magnetic suction plate on the inner side of the cabinet door that attracts the permanent magnet, and the magnetic suction plate is used to fix the trigger plate in the lighting state.

[0009] The present invention is further configured such that the reset button is a normally open self-reset switch, and the circuit is automatically connected when the trigger plate is disengaged.

[0010] The present invention is further configured such that when the trigger plate is reattached to the lighting switch socket, it presses the reset button to cut off the power to the lighting body.

[0011] The present invention is further configured such that the lighting body is an explosion-proof flat panel lamp.

[0012] By adopting the above technical solution, the beneficial effects that this utility model can achieve are: 1. By cooperating with the lighting switch base through the mechanical trigger mechanism on the inside of the cabinet door, when the cabinet door is opened, the flexible strip pulls the trigger plate away from the reset button, so that the lighting body is automatically lit. This solves the problem that existing mining switch cabinets have no lighting function and require hand-held lighting tools, thus improving the convenience of operation.

[0013] 2. The trigger plate can be reattached to the lighting switch socket and press the reset button to manually turn off the light when the cabinet door is open. This solves the problem that some switch cabinets with lighting functions cannot be manually turned off when the door is open, thus reducing energy waste.

[0014] 3. The trigger plate in the lighting state is fixed by the magnetic plate on the inside of the cabinet door, which prevents the trigger plate from shaking or the permanent magnet from being damaged. This solves the problem of insufficient stability of the trigger mechanism and enhances the durability of the equipment. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 : Example 1: This embodiment provides a mine switchgear with lighting function, including a cabinet body 1, a cabinet door 2 hinged to the cabinet body 1, and further including: The lighting assembly 3 includes a lighting body 30 installed on the top surface inside the cabinet 1, and a lighting switch base 31 with a reset button 32, wherein the reset button 32 is electrically connected to the lighting body 30. The mechanical triggering mechanism 4 includes a mounting base 40 fixed to the inside of the cabinet door 2, a flexible strip 41 with a fixed end 6 on the mounting base 40, and a trigger plate 42 on the free end 7 of the flexible strip 41. The trigger plate 42 can be separated and attracted to the lighting switch base 31 through a magnetic connector 43, and presses the reset button 32 to cut off the power to the lighting body 30. When the cabinet door 2 is opened, the trigger plate 42 is pulled away from the reset button 32 by the flexible strip 41, which powers the lighting body 30.

[0018] Cabinet 1, as the main structure of the mining switchgear, is used to house the internal electrical components, provide space for their installation, and protect them from the harsh environment of the mine, such as dust and humid air. Cabinet 1 is typically a rectangular, enclosed structure installed in a specific location within the mine. The various parts of cabinet 1 can be assembled together using welding, bolting, or other methods to ensure the overall structural robustness.

[0019] Cabinet door 2 is used to enclose cabinet 1, protecting the internal electrical components from external environmental influences, while also facilitating operation, inspection, and maintenance by operators. Cabinet door 2 is a flat structure adapted to the opening of cabinet 1, hinged to one side of cabinet 1, and can rotate around the hinge axis to open and close. When closed, it can be secured by a door lock or other device to ensure that cabinet door 2 is tightly closed.

[0020] Lighting component 3 provides illumination inside the mine switch cabinet, enabling operators to clearly see and operate the electrical components inside the cabinet in the dimly lit mine environment.

[0021] The lighting body 30, as the light-emitting component of the lighting assembly 3, converts electrical energy into light energy to provide sufficient light inside the switch cabinet. The lighting body 30 is usually a long strip or square lamp structure, which can be installed at the top center or both sides of the cabinet 1 space by means of screws or clips to achieve the best lighting effect, and can be connected to the lighting switch socket 31 and the power supply by wires to realize power-on light emission.

[0022] The lighting switch holder 31 is used to install the reset button 32 and serves as a connection node to realize circuit control of the lighting body 30. The lighting switch holder 31 is generally a block structure with internal wiring space for electrical connection lines and openings on the surface for installing the reset button 32. The lighting switch holder 31 can be installed in a suitable position inside the cabinet 1 by screws, usually near the trigger mechanism, so that the trigger plate 42 can act with it, and it is electrically connected to the lighting body 30 by wires. The reset button 32 is installed in the opening on its surface and is connected to the internal circuit.

[0023] The reset button 32 is used to control the circuit on / off of the lighting body 30. When the trigger plate 42 is pressed against it, it is in the open state, de-energizing the lighting body 30. When the trigger plate 42 is released, it automatically closes to connect the circuit, energizing the lighting body 30. The reset button 32 is soldered to the internal circuit of the lighting switch base 31 or connected by a plug-in. It protrudes from the lighting switch base 31, facilitating the pressing and releasing of the trigger plate 42, and realizing the control connection with the circuit of the lighting body 30.

[0024] The mechanical triggering mechanism 4 achieves automatic control of the lighting body 30 when the cabinet door 2 is opened and closed through mechanical action, without relying on electronic sensing elements, and is suitable for the harsh environment of the mine.

[0025] Mounting base 40 provides a fixed support point for flexible strip 41, enabling flexible strip 41 to be stably installed on the inside of cabinet door 2. Mounting base 40 is typically a block or plate structure with mounting holes or slots for fixing flexible strip 41. Mounting base 40 can be fixed to the inside of cabinet door 2 near lighting switch base 31 by screws or welding.

[0026] During the opening and closing of the cabinet door 2, the flexible strip 41 transmits the movement of the cabinet door 2, pulling the trigger plate 42 to separate from or adhere to the lighting switch base 31, thereby controlling the lighting body 30. The flexible strip 41 is typically long and flexible, able to bend but also withstand a certain amount of tension. Both ends of the flexible strip 41 are connected to the mounting base 40 and the trigger plate 42 respectively by welding, riveting, or screws to ensure reliable connection.

[0027] The trigger plate 42 can be detached and attracted to the lighting switch base 31 via the magnetic connector 43. Pressing the reset button 32 de-energizes the lighting body 30. When the cabinet door 2 is opened, it is pulled away from the reset button 32 by the flexible strip 41, energizing the lighting body 30. Simultaneously, in the lighting state, it can be attracted and fixed by the magnetic plate 5 on the inside of the cabinet door 2. The trigger plate 42 is typically a plate-shaped structure, with a flat surface on the side that contacts the lighting switch base 31 and the magnetic plate 5. The trigger plate 42 is fixed to the free end 7 of the flexible strip 41 by welding or gluing, and its attraction and detachment from the lighting switch base 31 are achieved through the magnetic connector 43.

[0028] The magnetic connector 43 is used to achieve the separable adsorption of the trigger plate 42 and the lighting switch base 31, so that the trigger plate 42 can stably press against the reset button 32 when the cabinet door 2 is closed, and can smoothly detach when the cabinet door 2 is opened. This design uses a magnetic connector 43, which has significant advantages over other separable structures such as buckles and pins in the mining environment: there is a lot of dust, high humidity and vibration in the mine. Buckles are prone to jamming due to dust accumulation, and pins are prone to corrosion and rust, resulting in poor separation. However, the magnetic connector 43 has no mechanical contact wear. It is connected by magnetic force without contact and can be adsorbed without precise alignment. It can withstand dust adhesion and slight vibration. Moreover, the metal magnetic connector 43 has stronger rust resistance, which can avoid failure caused by environmental factors, ensure that the trigger plate 42 is stably attracted and separated when the cabinet door 2 is opened and closed, and ensure the long-term reliable operation of the lighting switching mechanism.

[0029] In this embodiment, when the cabinet door 2 is closed, the trigger plate 42 is attached to the lighting switch base 31 via the magnetic connector 43. The trigger plate 42 presses against the reset button 32, causing the reset button 32 to be in the open state, and the lighting body 30 is de-energized. When the cabinet door 2 needs to be opened, the operator opens the cabinet door 2. The rotation of the cabinet door 2 causes the mounting base 40 installed on the inside of the cabinet door 2 to move. The mounting base 40 pulls the trigger plate 42 via the flexible strip 41. Because the flexible strip 41 is flexible, it can extend as the cabinet door 2 is opened, allowing the trigger plate 42 to overcome the attraction of the magnetic connector 43 and detach from the lighting switch base 31. The reset button 32 loses the pressure of the trigger plate 42 and automatically pops up and closes, connecting the circuit of the lighting body 30. The lighting body 30 is powered on and illuminates, providing lighting for the inside of the switch cabinet. When it is necessary to turn off the lighting while the cabinet door 2 is open, the operator holds the trigger plate 42 and pushes it toward the lighting switch base 31 until the magnetic connector 43 is attracted and fixed. The plane of the trigger plate 42 completely presses against the reset button 32, causing the reset button 32 to disconnect and the lighting body 30 to be de-energized.

[0030] Example 2: This embodiment provides a mine switchgear with lighting function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] The flexible strip 41 is a metal braided hose.

[0032] In this embodiment, a metal braided flexible hose is used as the flexible strip 41. Utilizing its combination of flexibility and rigidity, it satisfies the need for flexible deformation when the cabinet door 2 is opened, allowing the trigger plate 42 to detach from the lighting switch base 31. Simultaneously, it provides stable support when the cabinet door 2 is closed, ensuring that the trigger plate 42 accurately adheres to the lighting switch base 31 and reliably presses against the reset button 32. The metal braided structure also possesses wear resistance and resistance to corrosion in mining environments, avoiding the problems of easy breakage and deformation of ordinary flexible materials, thus ensuring the long-term stable operation of the triggering mechanism.

[0033] Example 3: This embodiment provides a mine switchgear with lighting function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0034] The magnetic connector 43 includes a permanent magnet 430 disposed on the trigger plate 42 and a magnetic conductor 431 disposed on the lighting switch base 31.

[0035] In this embodiment, the permanent magnet 430 and the magnetic conductor 431 work together to achieve reliable attraction and separation between the trigger plate 42 and the lighting switch holder 31. The permanent magnet 430 is a block or sheet structure, made of strong magnetic materials such as neodymium iron boron, and is fixed to the side of the trigger plate 42 near the lighting switch holder 31 by adhesive bonding or embedding. The magnetic conductor 431 is a metal sheet adapted to the permanent magnet 430, with a corresponding shape, and can also be fixed to the corresponding position of the lighting switch holder 31 by adhesive bonding or embedding. The two are attracted by magnetic force so that the trigger plate 42 stably presses against the reset button 32, ensuring that the lighting is turned off when the cabinet door 2 is closed. At the same time, the magnetic strength is moderate, which not only ensures the stability of the attraction, but also allows it to be smoothly separated by the flexible strip 41 when the cabinet door 2 is opened, providing a reliable magnetic foundation for automatic lighting switching.

[0036] Example 4: This embodiment provides a mine switchgear with lighting function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0037] The cabinet door 2 is provided with a magnetic suction plate 5 that attracts the permanent magnet 430. The magnetic suction plate 5 is used to fix the trigger plate 42 in the lighting state.

[0038] In this embodiment, the magnetic plate 5 provides auxiliary fixation for the trigger plate 42, preventing the trigger plate 42 from shaking or the permanent magnet 430 from being damaged under lighting conditions. The magnetic plate 5 is a rectangular metal plate adapted to the permanent magnet 430 on the trigger plate 42. It is fixed to the corresponding position on the inside of the cabinet door 2 by welding or bolting. When the cabinet door 2 is opened and the trigger plate 42 is removed from the lighting switch holder 31, the magnetic plate 5 and the permanent magnet 430 on the trigger plate 42 are magnetically attracted, firmly fixing the trigger plate 42 and preventing it from shaking with the cabinet door 2 or colliding with the cabinet body 1. This protects the structural integrity of the permanent magnet 430 and the trigger plate 42, and also prevents the shaking of the trigger plate 42 from affecting the subsequent accurate docking with the lighting switch holder 31, ensuring the long-term stable operation of the triggering mechanism.

[0039] Example 5: This embodiment provides a mine switchgear with lighting function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The reset button 32 is a normally open self-reset switch, which automatically connects the circuit when the trigger plate 42 is disconnected.

[0041] In this embodiment, a normally open self-resetting switch is used as the reset button 32. Combined with the disengagement action of the trigger plate 42, the lighting automatically responds when the cabinet door 2 is opened. The normally open type, rather than a normally closed type, ensures that the circuit automatically connects when the trigger plate 42 is disengaged, preventing lighting failure due to switch malfunction and meeting the high reliability requirements of mines. The normally open self-resetting switch remains open when pressed by the trigger plate 42. When the trigger plate 42 disengages, the internal spring structure drives the contacts to automatically close and connect the circuit. In mine operation scenarios, this design ensures that the trigger plate 42 disengages from the reset button 32 along with the flexible strip 41 the instant the cabinet door 2 is opened, and the switch automatically resets and connects without additional operation, instantly illuminating the lighting body 30 and completely solving the inconvenience of traditional switches requiring manual operation. Simultaneously, the self-resetting characteristic ensures that the circuit is reliably disconnected when the trigger plate 42 is pressed again, meeting the immediate lighting requirement of "lights up immediately upon opening the door" in the mine environment. Furthermore, the mechanical reset structure avoids the risk of electronic component failure in humid and dusty environments, improving the stability and safety of lighting control.

[0042] Example 6: This embodiment provides a mine switchgear with lighting function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] When the trigger plate 42 is reattached to the lighting switch base 31, it presses the reset button 32 to cut off the power to the lighting body 30.

[0044] In this embodiment, the trigger plate 42 is re-attached to the lighting switch base 31, pressing against the reset button 32 to achieve flexible light-off control when the cabinet door 2 is open. When the trigger plate 42 is manually re-attached to the magnetic body 431 of the lighting switch base 31, its flat surface will naturally press against the reset button 32 of the normally open self-resetting switch, forcing the switch contacts to open and cutting off the circuit of the lighting body 30. This mechanism is particularly practical in mine operations. For example, when continuous lighting is not required during maintenance, the light can be manually turned off without closing the cabinet door 2, avoiding the tediousness of repeatedly opening and closing the cabinet door 2 and reducing ineffective energy consumption. At the same time, with the stable attraction of the magnetic connector 43, it can be ensured that the trigger plate 42 continuously and reliably presses against the reset button 32, preventing accidental power outages or false lighting due to vibration or other factors. It takes into account both operational flexibility and control stability, adapting to the diverse needs of complex mine operation scenarios.

[0045] Example 7: This embodiment provides a mine switchgear with lighting function, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] The lighting body 30 is an explosion-proof flat panel lamp.

[0047] In this embodiment, an explosion-proof flat panel light is used as the lighting body 30, which is suitable for the special environment of mines where there are flammable and explosive substances such as gas and dust. The explosion-proof flat panel light adopts a sealed shell structure with a flat explosion-proof glass panel. The light body is fixed to the cabinet 1 by explosion-proof bolts and other explosion-proof connectors. Its internal circuit has undergone explosion-proof treatment such as flameproof and increased safety design to prevent electric sparks or high temperatures generated during the operation of the light from igniting the surrounding flammable and explosive gases. Compared with ordinary lamps, the flat structure of the explosion-proof flat panel light reduces the space occupied inside the cabinet 1, and the flat surface is not easy to accumulate dust, making it easy to clean and maintain. At the same time, its explosion-proof performance fundamentally avoids the risk of the lighting equipment becoming a safety hazard, ensuring that while meeting the lighting needs inside the cabinet, it also meets the stringent standards for safe operation in mines, protecting the safety of personnel and equipment underground.

[0048] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
