Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically to energy storage devices for wind-solar-storage microgrid systems. Background Technology

[0002] A microgrid is a small-scale power generation and distribution system consisting of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc.

[0003] A search revealed an existing patent (publication number: CN208299445U) that discloses a grid energy storage device. The energy storage box is connected to the power grid via a rectifier. The mounting frame inside the energy storage box is divided into multiple battery mounting chambers by partitions. Each battery box within a mounting chamber is equipped with a temperature control mechanism, a detection mechanism, and a heat dissipation mechanism. The connection mechanism includes connection terminals on the battery box and terminal connection holes in the battery mounting chambers. The mounting device includes a sliding mechanism, a positioning mechanism, and a locking mechanism. The sliding mechanism includes a groove on the partition, allowing the sliding member on the battery box to slide along the groove to embed the connection terminal into the terminal connection hole. The positioning mechanism has a positioning member on the inner side plate of the battery box, with a corresponding positioning part provided during battery installation. The locking mechanism has a locking member at the opening of the battery mounting chamber, with a corresponding locking part provided on the side plate of the battery box. The grid energy storage device provided by this utility model embodiment allows for convenient replacement and maintenance of the battery box.

[0004] Each battery mounting chamber is equipped with a heat dissipation mechanism to cool the battery. However, it has its drawbacks. Setting up multiple heat dissipation mechanisms increases the manufacturing cost, and each heat dissipation mechanism requires separate control to start, which is also cumbersome and inconvenient to use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an energy storage device for a wind-solar-storage microgrid system, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy storage device for a wind-solar-storage microgrid system, comprising a cabinet, inside which are installed multiple batteries, and at the rear of the cabinet, multiple heat-conducting blocks are fixed. A sealing frame is fixed to the rear surface of the cabinet, and multiple spacers are fixed inside the sealing frame. Multiple openings are provided at the top and bottom of the sealing frame, and multiple fixing pipes are fixed at the top and bottom of the sealing frame. A connecting pipe is fixed to the other end of the multiple fixing pipes, and a liquid guide pipe is fixed to the outer wall of the connecting pipe. A pump is fixed to the other end of the lower liquid guide pipe, and an inlet pipe is fixed to the other end of the pump.

[0007] Preferably, the bottom of the cabinet is fixed with multiple support legs.

[0008] Preferably, the rear surface of the heat-conducting block is integrally formed with multiple heat dissipation fins.

[0009] Preferably, the fixed tube below is provided with a sealing mechanism inside. The sealing mechanism includes a sealing plate, which is fixedly connected to the inner wall of the fixed tube. A leakage hole is opened at the top of the sealing plate. A round rod is slidably connected inside the fixed tube. A fixed cylinder is provided on the outer wall of the fixed tube. The outer wall of the round rod is slidably connected to the inner wall of the fixed cylinder. A sealing block is fixed at the bottom end of the round rod through the leakage hole.

[0010] Preferably, the cabinet has multiple movable slots at its lower interior, and movable plates are rotatably connected to the interior of each movable slot. The top end of the round rod passes through the bottom of the cabinet.

[0011] Preferably, a compression spring is fixed to the top of the fixed cylinder, and a ring is fixed to the other end of the compression spring. The inner wall of the ring and the outer wall of the rod are fixedly connected.

[0012] Beneficial effects This invention provides an energy storage device for a wind-solar-storage microgrid system. Compared with the prior art, it has the following advantages: 1. The energy storage device of this wind-solar-storage microgrid system is equipped with a pump, fixed pipe, connecting pipe, sealing frame, partition strip, connecting pipe and heat conduction block. The inlet pipe is connected to the external pipe and the external pipe is connected to the coolant storage tank. When the pump is started, the pump draws coolant. The coolant comes into contact with the heat conduction block to cool the heat conduction block. The heat conduction block cools the battery. This allows for simultaneous cooling of multiple batteries in a simple and convenient way.

[0013] 2. The energy storage device of this wind-solar-storage microgrid system has a sealing mechanism. After the battery is inserted into the cabinet, it will squeeze the movable plate. The movable plate will squeeze the round rod. The round rod will move downward with the sealing block, and the leakage hole will open. When there is no battery in some of the cabinet columns, the compression spring will push the ring to move. The ring will return to its original position with the round rod and the sealing block. In this way, the coolant will not flow to its column, reducing the loss of coolant. Attached Figure Description
