Description

Technical Field

[0001] This utility model relates to the field of power system automation equipment technology, specifically to a source-grid-load system control terminal housing mechanism. Background Technology

[0002] The source-grid-load system control terminal is the core equipment for realizing the coordinated regulation of "power source-grid-load" in the power system. Through real-time monitoring, intelligent analysis and dynamic control, it optimizes the balance of power supply and demand. It integrates data from new energy power generation, traditional power grid and diversified loads, and uses algorithms to achieve frequency regulation, peak shaving and valley filling and rapid fault isolation, supporting the stable operation of the power grid under the high proportion of renewable energy connected to the grid.

[0003] Chinese Patent CN221531082U discloses a smart energy terminal, including a housing with slots and a service control unit inside. The slots are used to connect functional modules. A cover has a human-machine interface (HMI) unit embedded in it for localized HMI interaction. The service control unit receives instructions from the HMI unit, drives the corresponding functional modules to perform tasks, and feeds back the results to the HMI unit for display. This smart energy terminal integrates the functions of traditional concentrators and dedicated transformers. The unit adopts a modular design and can be equipped with multiple functional modules. Based on the collected data, it can effectively monitor and regulate the load resources connected to the power grid, greatly improving the grid's regulation capabilities.

[0004] The housing of the source-grid-load system control terminal in the above-mentioned scheme and existing technology is usually a bottom box with a cover hinged to it. The bottom of the bottom box has an opening design to allow multiple sets of wires to pass through and connect to the internal circuit board. Although the open design of the source-grid-load system control terminal housing has the advantage of convenient wiring installation, the source-grid-load system control terminal is usually exposed to the air, and a large amount of dust enters the interior through the opening, causing circuit board failure and reducing service life. There is a lack of corresponding source-grid-load system control terminal housing structure with dustproof function, which needs to be improved and optimized. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The source-grid-load system control terminal housing mechanism proposed in this utility model mainly involves setting multiple sets of limiting slots on one side of the bottom box.

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 5 This utility model provides the following two technical solutions:

[0022] Example 1: A source-grid-load system control terminal housing mechanism includes a base box 1, a cover 2 hinged to one side of the base box 1, a heat dissipation grille 3 provided on one side of the base box 1, an mounting plate 4 fixedly connected to one side of the base box 1, a limiting slot 5 provided on one side of the base box 1, a wire hole adjustment component installed in the limiting slot, and a wire 7 clamped in the wire hole adjustment component; a first limiting groove 8 provided on one side of the base box 1, a second limiting groove 9 provided on one side of the base box 1, and a fixing block 10 fixedly connected to one side of the first limiting groove 8.

[0023] In use, the bottom box 1 is fixed to the cabinet or the position to be installed by the mounting plate 4 on one side. By opening the box cover 2, all the wires 7 are connected and squeezed and fixed by the wire hole adjustment component. After passing through the box cover 2 and connecting the other end, the box cover 2 is closed. The power supply of the source-grid-load system control terminal can be turned on to start normal monitoring and control operations. The heat dissipation grille 3 on one side of the bottom box 1 is used for heat dissipation of the equipment to prevent high temperature.

[0024] Example 2: Based on Example 1, the wire hole adjustment assembly includes a first pressing plate 601, a second pressing plate 602, a first spring 603, a semi-circular hole 604, and a cover plate 605. The first pressing plate 601 is slidably inserted into the limiting slot 5. A first spring 603 is fixedly connected to one side of the first pressing plate 601, and another side of the first spring 603 is fixedly connected to the inner wall of the limiting slot 5. The other side of the first pressing plate 601 has a semi-circular hole 604 and is pressed against the second pressing plate 602. The second pressing plate 602 is slidably inserted into the limiting slot 5. Another first spring 603 is fixedly connected to one side of the second pressing plate 602. A semi-circular hole 604 is provided on one side and the other side of 602. An electric wire 7 is inserted and extruded into the semi-circular hole 604. A cover plate 605 is slidably inserted into the first limiting groove 8. The semi-circular hole 604 corresponds to the first extrusion plate 601 and the second extrusion plate 602. A second spring 606 is fixedly connected to one side of the cover plate 605 and is fixedly connected to the fixing block 10. A baffle 607 is fixedly connected to one side of the cover plate 605. Two sets of connecting sliders 608 are symmetrically fixedly connected to one side of the first extrusion plate 601. The connecting sliders 608 are slidably engaged in the second limiting groove 9. A lever 609 is fixedly connected to one side of the connecting sliders 608.

[0025] In use, after connecting the wire 7 into the wiring inside the base box 1, the wire 7 is led out of the base box 1 through the wire hole adjustment assembly. The toggle plate 609 drives the first pressing plate 601 to press the first spring 603 into the limiting slot 5. As the toggle plate 609 moves the connecting slider 608 within the second limiting groove 9, it presses the baffle 607 on one side of the cover plate 605 and inwardly presses the second spring 606, causing the cover plate 605 to disengage from the semi-circular hole 604 on the first pressing plate 601. The wire 7 passes through and is secured in the corresponding semi-circular hole 604 position on the first pressing plate 601. Then, the toggle plate 609 is released, and under the rebound pressing action of the first spring 603, the first spring 606... The first extrusion plate 601 presses against the second extrusion plate 602 again. Under the rebound and extrusion action of the second spring 606, the cover plate 605 moves towards the semi-circular hole 604. The semi-circular hole 604 without wire 7 is covered by the cover plate 605 to prevent dust. Since the size of the semi-circular hole 604 on each set of semi-circular hole 604 wire hole adjustment components is different, inserting the wire between two sets of semi-circular holes 604 of appropriate size further prevents dust. The cover plate 605 also has a slight pressing effect on the wire 7 to increase the fixing effect. The elasticity of the first spring 603 is greater than that of the second spring 606. The wire hole adjustment component is well adapted to wires of various sizes and has a good dust prevention effect.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
