Description

Technical Field

[0001] This invention relates to the field of power grid equipment technology, and specifically discloses an intelligent power grid monitoring and management device. Background Technology

[0002] A power grid is the entire system comprised of substations and transmission lines of various voltage levels within a power system. A smart grid, on the other hand, is an upgrade of the existing power grid, endowing it with automatic monitoring, automatic management, and autonomous decision-making capabilities. Smart grids involve numerous electrical devices, most of which, besides cables and some large transformers, need to be centrally installed inside electrical cabinets. Outdoor electrical cabinets, in particular, face harsh environments, requiring them to be dustproof, moisture-proof, flood-proof, and possess good heat dissipation capabilities in high-temperature environments.

[0003] Utility model patent application number 2020203197667 discloses a modular smart grid switchgear, including a rear end plate. A main heat dissipation mechanism is installed at the rear end of the rear end plate. Two sets of main heat dissipation mechanisms are provided. Each main heat dissipation mechanism includes triangular fasteners, connecting plates, heat dissipation sealing plates, and a switch door. The triangular fasteners are fixedly connected to the rear end plate. Each set of main heat dissipation mechanisms has four triangular fasteners. The connecting plate is located at the rear end between the four triangular fasteners and is fixed to the triangular fasteners. The heat dissipation sealing plate is located inside the four triangular fasteners. The switch door is located between the connecting plates and is fixed to the connecting plates via a pivot and a snap-fit ​​connection. Heat dissipation strips are provided on both the heat dissipation sealing plate and the switch door. Rear heat dissipation sections are provided at the upper and lower ends of the rear end face of the rear end plate. This smart grid switchgear, through its main heat dissipation mechanism, can achieve active heat dissipation for the electrical equipment inside the cabinet, ensuring the stable operation of smart grid equipment in high-temperature environments. However, the design of the ventilation holes in this smart grid switchgear makes it ineffective at preventing dust and moisture. Furthermore, during the rainy season, heavy rain can easily cause water to enter the cabinet, damaging the internal electrical equipment and potentially paralyzing the entire power grid. Therefore, to address the aforementioned shortcomings of existing modular smart grid switchgear, this application designs a smart grid monitoring and management device that combines dustproof, moisture-proof, flood-proof, and active heat dissipation and cooling capabilities. Summary of the Invention

[0004] The present invention aims to provide a smart grid monitoring and management device that combines dustproof, moisture-proof, flood-proof and active heat dissipation and cooling performance, so as to solve the shortcomings of existing modular smart grid switchgear in managing and protecting electrical equipment in smart grids.

[0005] This invention is achieved through the following technical solution:

[0006] A smart grid monitoring and management device includes a cabinet, a base, a top cover, and electrical equipment. The cabinet is equipped with a flood-proof floating block, and the flood-proof floating block is connected to a vertically upward toothed surface. The inner wall of the cabinet is equipped with a vertical guide rail, and the vertical guide rail has several key block storage slots spaced vertically. Each key block storage slot is connected to a limit key block by a spring. The vertical guide rail is equipped with a sliding seat, and the sliding seat has a slot adapted to the limit key block. The front side of the sliding seat is connected to a mounting plate, and the electrical equipment is mounted on the mounting plate.

[0007] A connecting seat is fixed on the inner wall of the cabinet. A gear and a winding reel are rotatably connected in the connecting seat via a pin. The gear and the toothed surface are meshed. A guide wheel is provided at the upper end of the cabinet. A traction line is provided on the winding reel. The traction line passes around the guide wheel and is connected to the mounting plate.

[0008] During operation, when the smart grid monitoring and management equipment provided by this invention encounters flooding due to heavy rain, the buoyancy of the flood-proof float block caused by the rainwater entering the cabinet causes the toothed surface to move vertically upward. Then, the meshing action between the toothed surface and the gear causes the winding wheel to start rotating and winding. Finally, the traction action of the traction line causes the mounting plate on which the electrical equipment is installed to move upward along the vertical guide rail.

[0009] As the mounting plate moves upward, its sliding seat moves upward and presses the limiting key block into the key block receiving slot. Then, when the slot on the sliding seat aligns with the limiting key block, the limiting key block pops out instantly and extends into the slot, preventing the sliding seat and mounting plate from moving downward. This effectively avoids the possibility of electrical equipment on the mounting plate coming into contact with rainwater during floods, improves the flood prevention effect of the entire smart grid monitoring and management equipment, and ensures the stable operation of the smart grid.

[0010] As a further feature of the above solution, the top cover and the base are connected to the upper and lower ends of the cabinet respectively, the front side of the cabinet is provided with a cabinet door, the lower end of the side wall of the cabinet is provided with an air inlet, and the upper end is provided with an exhaust outlet.

[0011] As a further feature of the above solution, a guide rail is fixed on the side wall of the cabinet, and the side of the flood-proof float has a notch aligned with the air inlet and a guide slide that matches the guide rail.

[0012] As a further feature of the above solution, the top cover extends with a side baffle that is set downwards and blocks the outside of the exhaust port.

[0013] As a further feature of the above scheme, the limiting key block is trapezoidal in shape, and the inclined surface on the trapezoid is located at the lower outer side of the limiting key block.

[0014] As a further feature of the above solution, the cabinet is equipped with an information acquisition unit and a control unit. The information acquisition unit is connected to the signal input terminal of the control unit, and the cabinet is also equipped with a cooling fan connected to the signal output terminal of the control unit.

[0015] As a further feature of the above scheme, the signal acquisition unit includes a temperature sensor and a humidity sensor, an air outlet is provided on the cabinet, a cooling fan is located on the outside of the air outlet, and a desiccant assembly is provided on the inside of the air outlet.

[0016] As a further provision of the above solution, the desiccant assembly includes a storage box disposed on the inner wall of the cabinet, a flat mesh frame disposed in the storage box, a solid desiccant being filled in the flat mesh frame, and an electric telescopic rod disposed on the inner wall of the cabinet to push the flat mesh frame out of the storage box and cover the air outlet.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The smart grid monitoring and management equipment disclosed in this invention integrates relevant power equipment inside the cabinet for protection. During the operation of the equipment, it not only has a heat dissipation and cooling effect, but also can automatically push and fix the mounting plate on which the electrical equipment is installed in the event of flooding, so as to avoid the electrical equipment from coming into contact with rainwater as much as possible. This effectively ensures that the smart grid can still operate stably in the environment of flood disasters. The internal structure design of the entire management equipment is novel and has a good flood prevention effect.

[0019] The smart grid monitoring and management equipment disclosed in this invention is further improved in design in combination with the surrounding environment. It uses an information acquisition unit to monitor the internal temperature and air humidity of the cabinet in real time. When the detection result exceeds the set value, the control unit can control the cooling fan to actively dissipate heat. At the same time, it can also send out the desiccant from the storage box as needed to dry the air inside the cabinet, effectively improving the operating environment of electrical equipment in the smart grid and having a good cooling and moisture-proof effect.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-8 This application will be described in detail with reference to the embodiments. Example 1

[0031] Example 1 discloses a smart grid monitoring and management device, which is used for the centralized installation of electrical equipment in a smart grid, as shown in the attached figure. Figure 1 and attached Figure 2The main body of the device includes a cabinet 1, a base 2, and a top cover 3. The lower end of the cabinet 1 is connected to the base 2, and the upper end is connected to the top cover 3. A cabinet door 4 is hinged to the front side of the cabinet 1, allowing operators to open the door 4 and enter the cabinet 1 for maintenance or installation. Air inlets 101 are located at the lower ends of the left and right sides of the cabinet 1, and exhaust vents 102 are located at the upper ends of the left and right sides. Cold air from outside enters the cabinet 1 through the air inlets 101, then flows upwards within the cabinet, carrying away internal heat before being exhausted through the exhaust vents 102, thus providing good heat dissipation. Furthermore, to prevent rainwater from entering the cabinet 1 through the exhaust vents 102, downward-extending side baffles 301 are connected to both ends of the top cover 3. These side baffles 301 effectively block the outside of the exhaust vents 102, preventing rainwater from entering during rainy weather.

[0032] Reference Appendix Figure 1 and attached Figure 5 A flood-proof float 5 is installed at the bottom of the cabinet 1. This flood-proof float 5 is a hollow shell formed by injection molding of plastic granules, and notches 501 are reserved on its left and right sides to align with the air inlet 101, so as to prevent the sides of the flood-proof float 5 from blocking the air inlet 101. A vertically upward toothed surface 6 is fixedly connected to the upper surface of the flood-proof float 5. In the specific design, the toothed surface 6 is arranged in a U-shape, and toothed surfaces 601 are provided on both the left and right sides of the toothed surface 6. At the same time, in order for the flood-proof float 5 to move vertically upward under the action of buoyancy, a guide slide 502 is also provided on the flood-proof float 5, and a guide slide rail 7 that matches the guide slide 502 is fixedly connected to the inner wall of the cabinet 1.

[0033] Reference Appendix Figure 3 Appendix Figure 4 and attached Figure 6 Two vertical guide rails 8 are fixedly installed on the inner rear wall of the cabinet 1, and several key block storage slots 801 are provided on the side of the vertical guide rails 8 at intervals. Each key block storage slot 801 is connected to a limiting key block 803 by a spring 802. The limiting key block 803 is trapezoidal in shape, and the inclined surface of the trapezoid is located at the lower outer side of the limiting key block 803.

[0034] Reference Appendix Figure 3 and attached Figure 7Each vertical guide rail 8 has a sliding seat 9 that slides vertically, and a slot 901 adapted to the limiting key block 803 is opened on the side of the sliding seat 9. When the sliding seat 9 moves up and down along the vertical guide rail 8, its side first contacts the inclined surface on the limiting key block 803, thereby pressing the limiting key block 803 back into the key block receiving groove 801. When the slot 901 on the sliding seat 9 moves to the position of the limiting key block 803, it can instantly extend outward under the action of the spring 802 and lock into the inside of the slot 901, thereby restricting the downward movement of the sliding seat 9.

[0035] A mounting plate 10 is connected to the front end of the two sliding seats 9. Various electrical devices 11 are installed on the front side of the mounting plate 10 according to actual power requirements. The specific electrical devices 11 are conventional transformers, reactors, capacitors, switchgear, circuit breakers, instrument transformers, etc. After the various electrical devices 11 are fixed on the mounting plate 10, their wires can be gathered together and led out from the upper part of the cabinet 1. At the same time, this embodiment 1 also provides heat dissipation fins 12 on the back of the mounting plate 10. The heat dissipation fins 12 improve the heat dissipation and cooling effect of the electrical devices 11 to a certain extent.

[0036] Reference Appendix Figure 2 Appendix Figure 4 and attached Figure 8 Two connecting seats 13 are fixedly connected to the inner wall of the cabinet 1. Each connecting seat 13 is rotatably connected to a gear 14 and a winding reel 15 via a pin. The gear 14 meshes with the upper end of the corresponding tooth surface 601 on the toothed surface 6. A traction line 16 is connected to the winding reel 15. At the same time, a guide wheel 17 is fixedly installed on the inner wall of the cabinet 1 above the connecting seat 13, so that the traction line 16 passes around the guide wheel 17 and connects to the upper end of the mounting plate 10.

[0037] When the smart grid monitoring and management equipment disclosed in Embodiment 1 is running in a normal environment, the air inlet 101 and the exhaust 102 allow external cold air to enter the cabinet and flow away the heat generated on the electrical equipment 11, thus giving it a certain heat dissipation effect.

[0038] When heavy rain enters the cabinet 1, the increasing water level causes the flood-proof float 5 to move vertically upwards under buoyancy. During this upward movement, the meshing between the toothed surface 6 and the gear 14 rotates the winding reel 15, which in turn winds up the traction line 16, causing the mounting plate 10 to move upwards along the vertical guide rail 8. As the mounting plate 10 moves upwards, the interaction between the latch 901 on the sliding seat 9 and the upper limit block 803 on the vertical guide rail prevents it from moving downwards. This effectively prevents the electrical equipment 11 installed on the mounting plate 10 from contacting the rainwater inside the cabinet 1, ensuring the stable operation of the electrical equipment 11 even during heavy rain and improving the overall flood-proof performance of the smart grid monitoring and management equipment. Example 2

[0039] Example 2 discloses a smart grid monitoring and management device that further optimizes the technical solution in Example 1. The similarities with Example 1 will not be repeated. The differences between Example 2 and Example 1 are detailed in the appendix. Figure 1 Appendix Figure 3 and attached Figure 4 .

[0040] In this embodiment 2, an internal environment information acquisition unit and a control unit are also provided on the upper inner wall of the cabinet 1. The specific information acquisition unit includes a temperature sensor 18 and a humidity sensor 19. The control unit has a microcontroller 20 mounted on the inner wall of the cabinet 1, and the temperature sensor 18 and humidity sensor 19 are connected to the signal input terminals of the microcontroller 20. During the operation of this smart grid monitoring and management equipment, the temperature of the internal environment is collected by the temperature sensor 18, and the humidity of the internal air is collected by the humidity sensor 19.

[0041] An air outlet 103 is provided on one side wall of the cabinet 1. A cooling fan 21 is installed outside the air outlet 103 and is connected to the signal output terminal of the microcontroller 20, so that the cooling fan 21 is controlled by the microcontroller 20 to start and stop. In addition, in order to prevent impurities from being mixed in with the cold air sent into the cabinet 1 by the cooling fan 21, a filter screen 25 is also installed at the outer end of the cooling fan 21. The filter screen effectively filters the incoming cold air and ensures the purity of the air entering the cabinet 1.

[0042] In addition, a storage box 22 is installed on the inner wall of the cabinet 1 at the air outlet 103. The storage box 22 is open at one end near the air outlet 103, and a flat mesh frame 23 is installed in the storage box 22. The flat mesh frame 23 is filled with a large amount of solid desiccant. Then, an electric telescopic rod 24 is fixedly installed on the inner wall of the cabinet 1. The electric telescopic rod is also connected to the signal output terminal of the microcontroller 20. Then, the movable end of the electric telescopic rod 24 is inserted into the storage box 22 and connected to the flat mesh frame 23.

[0043] When the humidity sensor 19 detects excessive humidity inside the cabinet 1, the electric telescopic rod 24 is activated to push the flat mesh frame 23 to the air outlet 103. Then, the cooling fan 21 is activated, supplying a large amount of dry air into the cabinet 1. This dry air expels the humid air inside and also actively cools the electrical equipment 11 installed inside, improving its heat dissipation performance. In hot and dry weather, only the cooling fan 21 needs to be activated for active cooling.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
