Description

Technical Field

[0001] This utility model relates to the field of wind power energy storage technology, specifically to a modularly assembled integrated wind power energy storage device. Background Technology

[0002] Against the backdrop of a global push for clean energy transition, wind power has become a crucial pillar of renewable energy generation due to its abundant resources and environmental friendliness. Wind power-storage integration technology organically combines energy storage systems with wind power generation systems. When wind power generation is excessive, the storage device stores the excess electricity; when wind power generation is insufficient or during peak electricity demand, the stored electricity is released, thereby smoothing the wind power output curve.

[0003] In existing technologies, wind power energy storage is integrated by installing energy storage modules at the bottom of the wind turbine tower. Smoke and temperature sensors are used to monitor and protect the energy storage modules in real time. However, when the energy storage modules overheat and produce smoke, only a signal can be transmitted to notify maintenance personnel. It is not possible to take timely measures to prevent accidents, resulting in poor safety performance. Utility Model Content

[0004] The purpose of this utility model is to provide a modularly assembled wind power energy storage integrated device. In the existing technology, when the energy storage module overheats and produces smoke, the integrated device can only transmit signals to notify maintenance personnel, and cannot take timely measures to prevent accidents, resulting in poor safety performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modularly assembled integrated wind power and energy storage device, comprising:

[0006] An installation chamber for installing lithium battery packs is set up at the bottom of a wind power tower. The chamber wall is hinged with a door, and the door is equipped with a lock cylinder. A latch that cooperates with the lock cylinder pin is slidably set on the wall of the installation chamber. An arc-shaped plate is fixedly connected to the latch.

[0007] It also includes a drive gear that meshes with the latch, which is driven by a motor to rotate and cause the latch to make a circular motion around the central axis of the wind power tower, so that the latch is disengaged from the lock cylinder; it also includes a push rod that is horizontally movable in the installation chamber, the arc plate continues to move following the disengaged latch and drives the push rod to move toward the hinge end of the chamber door through the gear set, so that the push rod pushes the unlocked chamber door to rotate and open.

[0008] Preferably, the gear set includes a first gear and a second gear that mesh with each other. The first gear meshes with the end of the arc-shaped plate away from the latch, and the second gear meshes with the push rod.

[0009] Preferably, the inner wall of the latch is provided with an array of first teeth that are adapted to the drive gear. The shape of the arc-shaped plate is adapted to the wall of the mounting chamber, and the inner wall of the arc-shaped plate away from the latch is provided with an array of second teeth that are adapted to the first gear.

[0010] Preferably, the first gear is connected to the first rotating shaft via a bearing, and the second gear is connected to the second rotating shaft via a bearing. Mounting plates are connected to the top and bottom of both the first and second rotating shafts, and one side of each mounting plate is fixedly connected to the wall of the mounting chamber.

[0011] Preferably, the end of the push rod away from the door is provided with a third tooth, which is adapted to the second gear.

[0012] Preferably, the push rod is provided with a limiting block, and the limiting block is provided with a through groove. The push rod passes through the groove of the limiting block and moves horizontally along the through direction of the groove. One side of the limiting block is fixedly connected to the wall of the installation chamber by a limiting rod.

[0013] Preferably, the output shaft of the motor is coaxially connected to the drive gear, and a fixing plate is fixedly connected to the bottom of the motor, with one side of the fixing plate fixedly connected to the wall of the installation chamber.

[0014] Preferably, when the latch moves in a circular motion around the central axis of the wind power tower until it disengages from the lock cylinder, the first gear and the second gear rotate synchronously under the action of the arc plate, and drive the end of the push rod near the door to move synchronously until it contacts the door.

[0015] Preferably, after the push rod moves to contact the door, the latch continues to move, and the first gear and the second gear continue to rotate under the action of the arc plate, driving the push rod to push the door to rotate and open.

[0016] Preferably, a limiting sleeve for limiting the arc-shaped plate is fixedly installed on the inner wall of the installation room.

[0017] Preferably, the mounting chamber is provided with a limiting groove at the position corresponding to the latch for the latch to move.

[0018] In the above technical solution, the modularly assembled wind power energy storage integrated device provided by this utility model has the following beneficial effects:

[0019] This invention utilizes a latch, a drive gear, an arc-shaped plate, and a push rod. A motor drives the drive gear to rotate, causing the latch to rotate around the central axis of the wind turbine tower, disengaging it from the lock cylinder. The arc-shaped plate follows the disengaged latch, moving and, through the gear set, driving the push rod towards the hinged end of the door. This push rod then opens the unlocked door, enabling rapid ventilation and heat dissipation both inside and outside the installation chamber, and effectively expelling smoke. This prevents major safety accidents caused by lithium battery explosions due to increased internal temperature and pressure. Furthermore, it allows maintenance personnel to observe the internal situation from a distance, eliminating hazards before approaching for repairs, thus preventing injury and improving equipment safety.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-5As shown, a modular, integrated wind power and energy storage device includes:

[0030] An installation chamber 1, located at the base of a wind turbine tower, is used to install lithium battery packs. A door 2 is hinged to the wall of the chamber, and a lock cylinder 3 is installed on the door 2. A latch 4, which engages with the pin of the lock cylinder 3, is slidably installed on the wall of the installation chamber 1. An arc-shaped plate 5 is fixedly connected to the latch 4.

[0031] It also includes a drive gear 9 that meshes with the latch 4, which is driven to rotate by a motor and causes the latch 4 to make a circular motion around the central axis of the wind power tower, so that the latch 4 is disengaged from the lock core 3.

[0032] It also includes a horizontally movable push rod 6 installed in the installation chamber 1. The arc plate 5 continues to move following the disengaged latch 4 and drives the push rod 6 toward the hinge end of the chamber door 2 through the gear set, so that the push rod 6 pushes the unlocked chamber door 2 to rotate and open.

[0033] Specifically, by installing lithium battery packs in the installation chamber 1 at the bottom of the wind power tower, wind power energy storage is integrated, thus organically combining the energy storage system with the wind power generation system. When wind power generation is excessive, the energy storage device stores the excess electrical energy, and when wind power generation is insufficient or during peak electricity demand, the stored electrical energy is released, thereby smoothing the wind power output curve.

[0034] Furthermore, when the lithium battery pack generates smoke due to excessive temperature, the smoke sensor installed on the inner wall of the top of the installation chamber 1 will detect it and transmit the signal to the control center. The control center will drive the motor to rotate the drive gear 9, thereby causing the latch 4, which meshes with the drive gear 9, to move along the wall of the installation chamber 1 and make a circular motion around the central axis of the wind power tower in a direction away from the lock cylinder 3. This will cause the latch 4 to disengage from the lock cylinder 3, thereby automatically unlocking the chamber door 2.

[0035] Furthermore, when the latch 4 disengages from the lock cylinder 3, the arc plate 5 moves synchronously with the latch 4 to one end, engaging with the gear set located between the arc plate 5 and the push rod 6. The drive gear 9 continues to rotate, causing the latch 4 to drive the arc plate 5 to continue moving, which in turn drives the push rod 6 to move towards the hinge end of the door 2, thereby pushing the door 2 to rotate and open. Under the limiting action of the push rod 6, the door remains open, thus achieving rapid ventilation and heat dissipation inside and outside the installation chamber 1 and expelling smoke. This effectively prevents a major safety accident caused by the explosion of the lithium battery pack due to increased internal temperature and pressure in the installation chamber 1. At the same time, it allows maintenance personnel to observe the internal situation from a distance, eliminate dangers, and then approach for maintenance, avoiding personnel injury and thus improving the safety performance of the equipment.

[0036] As a further embodiment of this utility model, the gear set includes a first gear 7 and a second gear 8 that mesh with each other. The first gear 7 meshes with the end of the arc-shaped plate 5 away from the latch 4, and the second gear 8 meshes with the push rod 6. Specifically, the inner wall of the latch 4 is provided with an array of first teeth that are adapted to the drive gear 9. The shape of the arc-shaped plate 5 is adapted to the wall of the mounting chamber 1, and the inner wall of the arc-shaped plate 5 away from the latch 4 is provided with an array of second teeth that are adapted to the first gear 7.

[0037] The first gear 7 is connected to the first rotating shaft via a bearing, and the second gear 8 is connected to the second rotating shaft via a bearing. Mounting plates are connected to the top and bottom of both the first and second rotating shafts, and one side of each mounting plate is fixedly connected to the wall of the mounting chamber 1.

[0038] The end of the push rod 6 furthest from the door 2 is provided with a third tooth, which is adapted to the second gear 8. The push rod 6 is provided with a limiting block 10, and a through groove is provided in the limiting block 10. The push rod 6 passes through the groove of the limiting block 10 and moves horizontally along the through direction of the groove. One side of the limiting block 10 is fixedly connected to the wall of the installation chamber 1 by a limiting rod 11, so that the push rod 6 moves horizontally along the groove of the limiting block 10 under the drive of the second gear 8.

[0039] The output shaft of the motor is coaxially connected to the drive gear 9, and a fixing plate 12 is fixedly connected to the bottom of the motor. One side of the fixing plate 12 is fixedly connected to the wall of the installation chamber 1.

[0040] Specifically, the drive motor drives the active gear 9 to rotate, thereby causing the latch 4, which meshes with the active gear 9, to move on the installation chamber 1 and make a circular motion around the central axis of the wind power tower in a direction away from the lock core 3. At the same time, the arc plate 5 follows the latch 4 and makes a circular motion synchronously. Thus, the second teeth arranged in an array on the end of the arc plate 5 near the hinge end of the chamber door 2 drive the first gear 7 to rotate, thereby driving the second gear 8 to rotate in the opposite direction, thereby driving the push rod 6 to move towards the hinge end near the chamber door 2.

[0041] As a further embodiment of this utility model, when the latch 4 moves in a circular motion around the central axis of the wind power tower until it disengages from the lock core 3, the first gear 7 and the second gear 8 rotate synchronously under the action of the arc plate 5, and drive the push rod 6 to move synchronously to the end near the door 2 until it contacts the door 2.

[0042] As a further embodiment of this utility model, after the push rod 6 moves to contact the door 2, the latch 4 continues to move, and the first gear 7 and the second gear 8 continue to rotate under the action of the arc plate 5, which drives the push rod 6 to push the door 2 to rotate and open.

[0043] As a further embodiment of this utility model, a limiting sleeve for limiting the arc-shaped plate 5 is fixedly provided on the inner wall of the installation chamber 1. The limiting sleeve passes through the arc-shaped plate 5 and is used to guide the movement of the arc-shaped plate 5 and prevent it from deviating from the preset movement trajectory.

[0044] As a further embodiment of this utility model, a limiting groove for the movement of the lock 4 is provided at the position corresponding to the mounting chamber 1 and the lock 4.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
