Its operating principles primarily include voltage detection, signal processing, energy compensation, and voltage output.

[0003] The utility model with announcement number CN212784379U discloses a single-phase grouped rural power grid low-voltage management device. The utility model fixes the management device through a fixing pile of a matcher. A first positioning bar and a second positioning bar are fixedly installed between the fixing pile and the box body. A positioning plate is fixedly provided on one side of the positioning pile under the box body, which improves the fixing effect. The baffle provided on the top of the box body can guide rainwater and snowwater in rainy and snowy weather, so that the box body can be prevented from being eroded by rainwater. In case of strong sun, the fan provided can be used to vent air to the inside of the box body to relieve the heat inside the box body, protect the box body from damage, and improve work efficiency.

[0004] When the above-mentioned voltage management device lacks auxiliary lighting measures during maintenance, when workers need to perform maintenance inside it at night, they often need to hold a flashlight in one hand and perform maintenance operations in the cabinet with the other hand, which is very inconvenient. In many cases, they even need the cooperation of their colleagues to complete the maintenance work at night, resulting in low maintenance efficiency. Therefore, a terminal low voltage management device is proposed to address the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a terminal low voltage management device, in which a lighting lamp is provided in the voltage regulating device, which is independently powered by a storage power supply module. During maintenance at night, when the maintenance personnel open the cabinet door, the sliding power supply mechanism will be driven to move, so that the power supply circuit of the lighting lamp is connected, and the lighting lamp can automatically work for lighting, making it convenient for workers to carry out maintenance work with both hands and ensuring maintenance efficiency. It solves the technical problem that the device in the prior art lacks auxiliary lighting measures, so that workers need to hold a flashlight or wear lighting equipment in one hand during maintenance at night, which brings inconvenience to the maintenance work and leads to low maintenance efficiency.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A terminal low voltage management device includes a voltage regulating cabinet body, the front end of which is rotatably connected to a cabinet door, and a photovoltaic mechanism installed on the top of the voltage regulating cabinet body. The lower end surface of the top plate of the voltage regulating cabinet body is equipped with a lighting lamp, a storage power supply module and a sliding power supply mechanism. The storage power supply module can store the electric energy generated by the photovoltaic mechanism to power the lighting lamp.

[0008] Among them, the sliding power supply mechanism includes a rectangular frame sleeve installed on the top plate of the voltage regulating cabinet body and two static contacts. A sliding rod is slidingly arranged in the rectangular frame sleeve, and a moving contact piece is fixedly connected to its end, and the moving contact piece can fit with the two static contacts during the sliding process. At the same time, a hinged seat is fixedly arranged on the cabinet door, and a connecting rod is rotatably connected to it. The connecting rod is rotatably connected to the front end of the sliding rod. When the cabinet door is rotated and opened, the sliding rod is pulled forward by the connecting rod, so that the moving contact piece connected to its end slides between the static contacts and fits together. At this time, the circuit is connected. When the maintenance is completed and the cabinet door is closed, the connecting rod pushes the sliding rod to slide backward, the moving contact piece is separated from the static contact piece, and the lighting lamp is powered off and stops working.

[0009] In one possible implementation, the width of the gap between the static contact pieces is consistent with the thickness of the moving contact piece. This structural form can ensure that the moving contact piece can fit tightly with the static contact piece after sliding in, and there will be no poor contact due to the existence of gaps. Both are made of copper sheets, and copper material can ensure the conductive effect.

[0010] In one possible implementation, the photovoltaic mechanism is electrically connected to the storage power supply module, the negative output interface of the storage power supply module is electrically connected to the negative interface of the lighting lamp through a wire, the positive output interface of the storage power supply module is electrically connected to one of the static contacts through a wire, and the positive interface of the lighting lamp is electrically connected to the other static contact through a wire. The above-mentioned structural form can constitute a complete power supply circuit for the lighting lamp, that is, the storage power supply module serves as a power source, and the static contact and the moving contact serve as switches. Only when the two contacts are in contact, the circuit is energized and the lighting lamp works.

[0011] In one possible implementation, a guide groove is provided on the side of the sliding rod, and a guide edge matching the guide groove is fixedly provided on the inner wall of the rectangular frame sleeve. The clamping effect between the guide groove and the guide edge can improve the stability of the sliding rod during the sliding process. In addition, the moving contact piece is fixedly connected to the end of the sliding rod through an insulating seat. The insulating seat can be used to isolate the sliding rod and the moving contact piece so that no electricity can be passed between the two.

[0012] In one possible implementation, four plug connectors are fixedly provided on the back of the voltage regulating cabinet body, and the plug connectors are plugged into a mounting bracket matching the voltage regulating cabinet body. The mounting bracket includes a card connector for the plug connector to be connected, and the card connectors are fixedly connected through a connecting bracket. During installation, it is only necessary to first install the connecting bracket in the specified position, and then insert the plug connector into the card connector, and hang the entire voltage regulating cabinet body on the connecting bracket. There is no need to move the entire device for positioning and installation, which can reduce the difficulty of installation and improve installation efficiency.

[0013] In one possible implementation, the plug connector includes a connecting plate, and a T-shaped card plate is fixedly provided on the front end surface of the connecting plate. The T-shaped card plate can produce a clamping effect with the card connector and cooperate with gravity to achieve fixed installation of the voltage regulating cabinet body. The bottom end of the T-shaped card plate is processed to form an oblique opening, which can facilitate the insertion of the plug connector into the card connector.

[0014] In one possible implementation, a T-shaped slot matching the size of the T-shaped card plate is provided on the card connector. The T-shaped slot can cooperate with the T-shaped card plate to play a role of clamping and fixing. The T-shaped slot is processed to form a bevel, and the bevel can facilitate the insertion of the plug connector, and a bottom baffle that can cover the T-shaped slot is fixed at the bottom end of the card connector.

[0015] In one possible implementation, a groove is provided on the top of the voltage regulating cabinet body, and the photovoltaic mechanism includes a photovoltaic panel, which is embedded in the groove on the top of the voltage regulating cabinet body. This installation method will not cause the installation site to bulge outward and affect the smoothness of drainage. The surface of the photovoltaic panel is covered with a high-transmittance glass cover, which can protect the photovoltaic panel and reduce maintenance costs.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] A lighting lamp is provided in the device, which is powered separately by the battery power supply module. During maintenance at night, when the maintenance personnel open the cabinet door, the sliding power supply mechanism will be driven to move, so that the power supply circuit of the lighting lamp is connected, and the lighting lamp can automatically work to illuminate, making it convenient for workers to carry out maintenance work with both hands and ensuring maintenance efficiency. Specifically, when the cabinet door rotates, the sliding rod is pulled forward by the connecting rod, so that the moving contact piece connected to its end slides between the static contacts and fits together. At this time, the circuit is connected. When the maintenance is completed and the cabinet door is closed, the connecting rod pushes the sliding rod to slide backward, the moving contact piece is separated from the static contact piece, and the lighting lamp is powered off and stops working.

[0026] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

The storage power supply module 4 can store the electric energy generated by the photovoltaic mechanism 2 to supply power for the lighting lamp 3.

[0028] like Figure 3 - Figure 4As shown, the sliding power supply mechanism 5 includes a rectangular frame sleeve 51 and two static contacts 53 installed on the top plate of the voltage regulating cabinet body 1. A sliding rod 52 is slidably arranged in the rectangular frame sleeve 51, and a moving contact piece 54 is fixedly connected to its end, and the moving contact piece 54 can fit with the two static contacts 53 during the sliding process. At the same time, a hinge seat 55 is fixedly arranged on the cabinet door 11, and a connecting rod 56 is rotatably connected to it. The connecting rod 56 is rotatably connected to the front end of the sliding rod 52. When the cabinet door 11 is rotated and opened, the sliding rod 52 is pulled forward by the connecting rod 56, so that the moving contact piece 54 connected to its end slides between the static contacts 53 and fits together. At this time, the circuit is connected. When the maintenance is completed and the cabinet door 11 is closed, the connecting rod 56 pushes the sliding rod 52 to slide backward, the moving contact piece 54 is separated from the static contact piece 53, and the lighting lamp 3 is powered off and stops working.

[0029] Among them, the gap width between the static contact pieces 53 is consistent with the thickness of the moving contact piece 54. This structural form can ensure that the moving contact piece 54 can fit tightly with the static contact piece 53 after sliding in, and there will be no poor contact due to the existence of gaps. Both are made of copper sheets, and copper material can ensure the conductive effect.

[0030] In addition, in order to form a complete power supply circuit for the lighting lamp 3, the photovoltaic mechanism 2 is electrically connected to the storage power supply module 4, the negative output interface of the storage power supply module 4 is electrically connected to the negative interface of the lighting lamp 3 through the wire belt 31, the positive output interface of the storage power supply module 4 is electrically connected to one of the static contact pieces 53 through the wire belt 31, and the positive interface of the lighting lamp 3 is electrically connected to the other static contact piece 53 through the wire belt 31. The above-mentioned structural form can form a complete power supply circuit for the lighting lamp 3, that is, the storage power supply module 4 serves as a power source, and the static contact piece 53 and the moving contact piece 54 serve as switches.

The clamping effect between the guide groove 521 and the guide ridge 511 can improve the stability of the sliding rod 52 during the sliding process. In addition, the moving contact piece 54 is fixedly connected to the end of the sliding rod 52 through the insulating seat 541. The insulating seat 541 can be used to isolate the sliding rod 52 and the moving contact piece 54, so that no electricity can be passed between the two.

[0032] like Figure 5 - Figure 6As shown, four plug connectors 6 are fixedly provided on the back of the voltage regulating cabinet body 1. The plug connectors 6 are plugged into the mounting frame matched with the voltage regulating cabinet body 1. The mounting frame includes a card connector 7 for plugging and connecting the plug connector 6. The card connectors 7 are fixedly connected through a connecting frame 8. During installation, it is only necessary to first install the connecting frame 8 in the specified position, and then insert the plug connector 6 into the card connector 7, and hang the entire voltage regulating cabinet body 1 on the connecting frame 8. There is no need to move the entire device for positioning and installation, which can reduce the difficulty of installation and improve the installation efficiency.

[0033] Among them, the plug connector 6 includes a connecting plate 61, and a T-shaped clamping plate 62 is fixedly provided on the front end surface of the connecting plate 61. The T-shaped clamping plate 62 can produce a clamping effect with the clamping connector 7, and cooperate with the action of gravity to realize the fixed installation of the voltage regulating cabinet body 1. The bottom end of the T-shaped clamping plate 62 is processed to form an oblique opening 63, which can facilitate the insertion of the plug connector 6 into the clamping connector 7.

[0034] In addition, a T-shaped slot 71 matching the size of the T-shaped card plate 62 is provided on the card connector 7. The T-shaped slot 71 can cooperate with the T-shaped card plate 62 to play a role of clamping and fixing. The notch of the T-shaped slot 71 is processed to form a bevel 72, and the bevel 72 can facilitate the insertion of the plug connector 6, and a bottom baffle 73 that can cover the T-shaped slot 71 is fixed at the bottom end of the card connector 7.

[0035] like Figure 5 As shown, a groove is provided on the top of the voltage regulating cabinet body 1, and the photovoltaic mechanism 2 includes a photovoltaic panel 21, which is embedded in the groove on the top of the voltage regulating cabinet body 1.

During maintenance at night, when the maintenance personnel open the cabinet door 11, the sliding power supply mechanism 5 will be driven to move, so that the power supply circuit of the lighting lamp 3 is connected, allowing the lighting lamp 3 to work automatically for lighting, making it convenient for workers to carry out maintenance work with both hands and ensuring maintenance efficiency.

[0038] In order to realize the above-mentioned automatic power supply, the photovoltaic mechanism 2 is electrically connected to the storage power supply module 4, the negative output interface of the storage power supply module 4 is electrically connected to the negative interface of the lighting lamp 3 through the wire belt 31, the positive output interface of the storage power supply module 4 is electrically connected to one of the static contact pieces 53 through the wire belt 31, and the positive interface of the lighting lamp 3 is electrically connected to the other static contact piece 53 through the wire belt 31. The above-mentioned structural form can constitute a complete power supply circuit for the lighting lamp 3, that is, the storage power supply module 4 serves as a power source, and the static contact piece 53 and the moving contact piece 54 serve as switches. Only when the two contacts are in contact, the circuit is energized and the lighting lamp 3 works.

[0039] The on-off principle of the sliding power supply mechanism 5 is specifically manifested as follows: when the cabinet door 11 rotates, the sliding rod 52 is pulled forward by the connecting rod 56, so that the moving contact piece 54 connected to its end slides between the static contact pieces 53 and fits together. At this time, the circuit is connected.
