Description

Technical Field

[0001] This utility model relates to the field of pumped storage control technology, and more specifically, to a cluster control device for multi-machine combined pumped storage. Background Technology

[0002] Multi-unit pumped storage refers to a pumped storage power station in which multiple pumped storage units work together to complete the cycle of "pumping and storing water" and "generating and releasing energy" to achieve peak shaving, valley filling, and frequency regulation functions for the power grid. Its core is to operate multiple units as a whole system, rather than individual units working independently, thereby improving the overall performance of the power station and its support capacity for the power grid. The cluster control device coordinates the working status of multiple units (such as pumping, generating, and shutting down) through unified algorithms and instructions to optimize the overall operating efficiency, stability, and response speed to better adapt to the needs of the power grid.

[0003] Existing cluster control devices can display the operating status and set parameters through touch screens and operation buttons. However, it is inconvenient to protect the touch screens and operation buttons. In the complex operating environment of power plants, they are susceptible to failure due to various factors. For example, although the control room of a pumped storage power station is relatively enclosed, dust and moisture still exist. Long-term adhesion to the touch screen surface can lead to blurred display, decreased touch sensitivity, and even accidental touches. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cluster control device for multi-machine joint pumped storage, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cluster control device for multi-unit combined pumped storage, comprising a support frame and a cluster controller body, wherein the bottom end of the cluster controller body is fixedly connected to the support frame, and upright plates are fixedly connected to both sides of the top edge of the support frame, and U-shaped plates are fixedly connected to the opposite sides of the two upright plates, and a protective assembly is provided between the two upright plates, the protective assembly comprising a self-locking motor, a rotating shaft, a protective cloth, a connecting plate, two sliding plates, two sliding rods and two limiting plates, the self-locking motor is fixedly installed on one side of one of the upright plates, and the output shaft end of the self-locking motor is fixedly connected to the rotating shaft, the two ends of the rotating shaft are movably connected to the two upright plates through bearings, one side of the protective cloth is fixedly connected to the rotating shaft, and the other side of the protective cloth is fixedly connected to the connecting plate.

[0006] Furthermore, the two opposing sides of the two slide plates are fixedly connected to the connecting plates, and the two connecting plates are movably sleeved on the two slide rods, and the front and rear ends of the two slide rods are fixedly connected to the two U-shaped plates respectively.

[0007] Furthermore, both limiting plates are fixedly sleeved on the rotating shaft, and the opposite sides of the two limiting plates are in contact with the protective cloth.

[0008] As can be seen, in the above technical solution, the protective cloth can be limited by two limiting plates to prevent the protective cloth from deviating from the rotating shaft.

[0009] Furthermore, springs are fitted onto both of the sliding rods, and the front and rear ends of the two springs are respectively fixedly connected to the two U-shaped plates and the two sliding plates.

[0010] As can be seen, in the above technical solution, the two springs rebound and drive the connecting plate and protective cloth to reset.

[0011] Furthermore, a guide rod is fixedly connected between the two upright plates, and the outer side of the guide rod is in contact with the protective cloth.

[0012] As can be seen, in the above technical solution, the protective cloth can be guided by the guide rod so that the protective cloth is located at the top of the support frame.

[0013] Furthermore, a partition component is provided on the front side of the main body of the cluster controller, the partition component including a partition frame, a locking block and a locking bolt.

[0014] Furthermore, the rear side of the partition frame is in contact with the main body of the cluster controller, the top of the card block is fixedly connected to the partition frame, and the card block is fixed to the support frame by locking bolts.

[0015] It can be seen that the above technical solution facilitates the physical separation of adjacent wiring terminals.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model protects the touch screen and operation buttons on the top of the cluster controller body with a protective cloth. The self-locking motor drives the rotating shaft to rotate, and the protective cloth is wrapped around the rotating shaft, thus exposing the touch screen and operation buttons. At the same time, the protective cloth drives two springs to stretch. When the self-locking motor reverses, the two springs rebound and drive the connecting plate and protective cloth to reset. The operation is simple and convenient for protecting the touch screen and operation buttons on the top of the support frame.

[0018] 2. This utility model allows for the physical separation of adjacent wires by sequentially inserting multiple connectors into the corresponding sockets on the front side of the cluster controller body. This prevents poor contact or short circuits caused by the connectors shaking or tangling. When it is necessary to replace the separator with a different specification, such as to accommodate the spacing of thicker connectors, simply rotate the locking bolt to unscrew it from the threaded hole of the support frame and release it from the clip. This releases the separator from the support frame and allows for easy disassembly. The structure is simple and easy to use. Attached Figure Description

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Refer to the instruction manual appendix Figure 1-5 This embodiment of a cluster control device for multi-unit combined pumped storage includes a support frame 1 and a cluster controller body 2. The bottom end of the cluster controller body 2 is fixedly connected to the support frame 1. Upright plates 7 are fixedly connected to the top two edges of the support frame 1. U-shaped plates 6 are fixedly connected to the opposite sides of the two upright plates 7. A protective component 3 is provided between the two upright plates 7. The protective component 3 includes a self-locking motor 301, a rotating shaft 302, a protective cloth 303, a connecting plate 304, two sliding plates 305, two sliding rods 306, and two limiting plates 307. The self-locking motor 301 is fixedly installed on one side of one of the upright plates 7, and the output shaft end of the self-locking motor 301 is fixedly connected to the rotating shaft 302. Both ends of the rotating shaft 302 are movably connected to the two upright plates 7 through bearings. One side of the protective cloth 303 is fixedly connected to the rotating shaft 302, and the other side of the protective cloth 303 is fixedly connected to the connecting plate 304.

[0028] Furthermore, the two sliding plates 305 are fixedly connected to the connecting plate 304 on opposite sides, and the two connecting plates 304 are movably sleeved on the two sliding rods 306 respectively. The front and rear ends of the two sliding rods 306 are fixedly connected to the two U-shaped plates 6 respectively. The two limiting plates 307 are fixedly sleeved on the rotating shaft 302, and the opposite sides of the two limiting plates 307 are in contact with the protective cloth 303. Springs 5 ​​are sleeved on the two sliding rods 306, and the front and rear ends of the two springs 5 ​​are fixedly connected to the two U-shaped plates 6 and the two sliding plates 305 respectively. A guide rod 4 is fixedly connected between the two upright plates 7, and the outer side of the guide rod 4 is in contact with the protective cloth 303.

[0029] Furthermore, a partition component 8 is provided on the front side of the cluster controller body 2. The partition component 8 includes a partition frame 801, a locking block 802, and a locking bolt 803. The rear side of the partition frame 801 is in contact with the cluster controller body 2. The top of the locking block 802 is fixedly connected to the partition frame 801, and the locking block 802 is fixed to the support frame 1 by the locking bolt 803.

[0030] After inserting multiple connectors sequentially into the corresponding sockets on the front side of the cluster controller body 2, adjacent connectors can be physically separated by the separator 801. This prevents poor contact or short circuits caused by connectors shaking or tangling. When it is necessary to replace the separator with a different specification, such as to accommodate a larger connector spacing, simply rotate the locking bolt 803 to unscrew it from the threaded hole of the support frame 1 and release it from the clip 802. This releases the separator 801 from the support frame 1, allowing for easy disassembly. During installation, align the clip 802 of the separator 801 with the slot of the support frame 1, then rotate the locking bolt 803 in the opposite direction to allow it to pass through the clip 802 and tighten it onto the support frame 1. This completes the fixing process. The structure is simple and easy to use.

[0031] The usage method of this embodiment is as follows:

[0032] In use, the protective cloth 303 protects the touch screen and operation buttons on the top of the cluster controller body 2. The self-locking motor 301 is activated, causing the rotating shaft 302 to rotate and the protective cloth 303 to wrap around it, thus exposing the touch screen and operation buttons. Simultaneously, the protective cloth 303 moves the connecting plate 304 horizontally, causing the two sliding plates 305 to slide on the two sliding rods 306 respectively, preventing the connecting plate 304 from deflecting during horizontal movement. This, in turn, stretches the two springs 5. When the self-locking motor 301 reverses, the two springs 5 ​​rebound, resetting the connecting plate 304 and the protective cloth 303. The operation is simple and convenient for protecting the touch screen and operation buttons on the top of the support frame 1. The guide rod 4 guides the protective cloth 303 to ensure it is positioned at the top of the support frame 1. Two limiting plates 307 limit the protective cloth 303 to prevent it from deviating from the rotating shaft 302.

[0033] It is worth noting that the working principle of the main body 2 of the cluster controller is as follows: the unit communication module on the main body 2 of the cluster controller is connected to the local controller of multiple pumped storage units to collect the operating data of each unit in real time; at the same time, the grid interface module receives grid dispatch instructions, and all data is aggregated to the central control unit in the main body 2 of the cluster controller. The central control unit sends the instructions after decision to the local controller of each unit through the unit communication module to control the unit to switch states, adjust power or guide vane opening. When the grid is in a low electricity demand period, and there is a surplus of new energy power generation such as wind power and photovoltaic power or redundant thermal power output, the grid dispatch system sends a "pumped storage" instruction to the main body 2 of the cluster controller.

[0034] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
