[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Embodiment: A robot arm for quickly replacing battery packs includes a robot arm 1 and a cross slide 2. The robot arm 1 includes a moving arm 101 and a telescopic plate 110. The moving arm 101 is fixedly connected to the moving seat of the cross slide 2; the telescopic arm 102 is slidably inserted in the moving arm 101, and a receiving cavity 103 is opened in the telescopic arm 102 for accommodating the replaced battery pack. The receiving cavity 103 has a single-sided inclined surface. The telescopic arm 102 is fixedly connected to one side of the inclined surface of the receiving cavity 103 with two contact plates 104. The two contact plates 104 are rotatably connected to each other through a rotating shaft. The driving belt 105 and the side plate of the telescopic arm 102 are fixedly connected to the driving motor 106, the output end of the driving motor 106 is fixedly connected to the rotating shaft of the transmission belt 105, the telescopic plate 110 is slidably inserted in the top plate of the telescopic arm 102, and the end of the telescopic plate 110 is rotatably connected to the iron baffle 111 through a torsion spring. After the iron baffle 111 moves to the top of the inclined surface of the accommodating chamber 103, it and the telescopic plate 110 jointly seal the accommodating chamber 103. An electric push rod 116 is fixedly connected to the inner vertical wall of the mobile arm 101, and the output end of the electric push rod 116 is fixedly connected to the side plate of the telescopic arm 102.

[0023] The cross slide 2 serves as a driving mechanism, driving the movable arm 101 to move on the X-axis and the Z-axis, that is, driving the movable arm 101 to move in the horizontal and vertical directions. When the battery pack has abnormal temperature, unstable current or voltage, the cross slide 2 quickly drives the movable arm 101 to move to the position of the faulty battery pack. Driven by the electric push rod 116, the telescopic arm 102 is pushed toward the position of the faulty battery pack. Driven by the drive motor 106, the transmission belt 105 rotates through the rotating shaft to quickly transport the faulty battery pack to the accommodating cavity 103 of the telescopic arm 102. In this process, the inclined state of the iron baffle 111 will hinder the faulty battery pack from continuing to move toward the top plate of the telescopic arm 102, forcing the faulty battery pack to slide along the inclined surface of the accommodating cavity 103 until the faulty battery pack completely slides into the telescopic arm 102. In this way, the faulty battery pack can be taken and stored.

[0024] The top plate of the telescopic arm 102 extends backward to form a support plate 117, one side of the support plate 117 is fixedly connected to the support frame 115, and the side wall of the support frame 115 is fixedly connected to the battery push rod 107. The support plate 117 is fixedly connected to the battery push rod 107 through the support frame, and the output end of the battery push rod 107 is fixedly connected to the battery push plate 108.

[0025] The iron baffle 111 is distributed obliquely upward relative to the telescopic plate 110 , and an electromagnet 112 is embedded and fixedly installed in the top of the inclined surface of the accommodating cavity 103 . The electromagnet 112 generates a magnetic attraction on the iron baffle 111 .

[0026] After the faulty battery pack completely slides into the telescopic arm 102, the battery push rod 107 starts to push the intact battery pack on the top of the telescopic arm 102 to the original position of the faulty battery pack, and pushes it back to the installation position of the battery pack through the thrust, thereby completing the replacement of the battery pack.

[0027] When the battery push rod 107 pushes the intact battery pack, the intact battery pack will contact the tilted iron baffle 111. The iron baffle 111 contacts the side of the battery pack under the elastic force of the torsion spring. Under the extrusion, the telescopic plate 110 will slide out from the top plate of the telescopic arm 102 until the iron baffle 111 moves above the electromagnet 112. At the same time, the telescopic plate 110 moves to the limit and cannot move further. As the battery pack continues to move, the iron baffle 111 gradually tends to a horizontal state and is attracted by the magnetic force of the electromagnet 112. Under the magnetic adsorption of the electromagnet 112, the iron baffle 111 gradually tends to a horizontal state. When the iron baffle 111 is used, it is completely absorbed. At this time, the iron baffle 111 and the telescopic plate 110 completely cover the gap above the accommodating chamber 103, so that the accommodating chamber 103 forms a closed space. The sealing strips at the bottom of the telescopic plate 110 and the iron baffle 111 are used to form a simple sealed space in the accommodating chamber 103, so that the faulty battery pack loses the gas conditions for explosion, so that even if overheating and combustion occur, the oxygen in the closed space of the accommodating chamber 103 will be quickly exhausted, shortening the intensity and duration of combustion, reducing the scope of combustion, and avoiding affecting other components within the range of the energy storage power station.

[0028] A revolving door is hinged on one side of the telescopic arm 102. The hinge of the revolving door is at the bottom and is locked to the side panel of the telescopic arm 102 with a lock. The lock can be opened when necessary to take out the faulty battery pack in the telescopic arm 102.

[0029] A rotating plate 109 is rotatably connected to the top plate of the telescopic arm 102, and the bottom of the rotating plate 109 extends downward and contacts the side plates of the telescopic arm 102. The side plates of the telescopic arm 102 limit the rotation direction of the telescopic arm 102, and the top plate of the telescopic arm 102 is provided with a slot for the rotating plate 109 to rotate.

[0030] A storage box 4 is placed on one side of the telescopic arm 102, and a battery pack is contained in the storage box 4. The outer side of the storage box 4 is fixedly connected to a push rod 5 through a connecting frame, and the output end of the push rod 5 is fixedly connected to a push plate 6. A lifting plate 7 is slidably connected inside the storage box 4, and a spring is fixedly connected between the storage box 4 and the lifting plate 7. A slot is provided on one side panel of the storage box 4 for the battery pack to pass through.

[0031] After the battery pack is replaced, the ejector rod 5 is activated to push the battery pack in the storage box 4 to the top of the telescopic arm 102. During this process, the new battery pack will contact the rotating plate 109 and, under the action of the thrust, force the top of the rotating plate 109 to rotate toward the top plate of the telescopic arm 102. The battery pack will slide on the rotating plate 109 and at the same time have an inclined angle with the telescopic arm 102. After the battery pack is about to completely fall into the top of the telescopic arm 102, the rotating plate 109 is reset under the elastic support of the torsion spring, and the battery pack will be at the top of the telescopic arm 102 waiting for the next replacement.

[0032] The energy storage power station using the above-mentioned robotic arm includes an energy storage cabinet 3, which includes a cabinet body 301 and a limit frame 304. The rear side of the cabinet body 301 is fixedly connected to a hollow back plate 302, and a plurality of battery placement plates 303 are fixedly connected to the cabinet body 301 through a bracket. The battery placement plates 303 are embedded and fixedly installed with a first piston cylinder 308, a second piston cylinder 309 and a guide tube 310. The two ends of the second piston cylinder 309 are respectively passed through and fixedly connected to the side plates of the first piston cylinder 308 and the guide tube 310. A pressure piston plate 311 is slidably inserted in the first piston cylinder 308, and a movable piston 313 is slidably inserted in the second piston cylinder 309. The end of the movable piston 313 is fixedly connected to a friction block 314. When the telescopic arm 102 slides out of the movable arm 101, the contact plate 104 contacts the pressure piston plate 311.

[0033] As the telescopic arm 102 slides outward, the contact plate 104 and the transmission belt 105 will gradually approach the battery placement plate 303. When the contact plate 104 contacts the pressure piston plate 311, the contact plate 104 squeezes the pressure piston plate 311, and the oil in the first piston cylinder 308 is squeezed into the second piston cylinder 309 through the guide tube 310. The hydraulic pressure in the second piston cylinder 309 will be transmitted to the moving piston 313, causing the friction block 314 in contact with the bottom of the faulty battery pack to slide outward, forcing the faulty battery pack to separate from the wires connected to it. As the telescopic arm 102 continues to penetrate deeper, the faulty battery pack will contact the rotating transmission belt 105 and be brought into the accommodating chamber 103. In this way, the faulty battery pack can be effectively helped to quickly disconnect from the wires, reducing the difficulty of removing the faulty battery pack.

[0034] A hook groove 312 is provided at the end of the pressure piston plate 311, and the bottom of the contact plate 104 is fixedly connected to a fixing frame 113, and a rotating hook 114 is rotatably connected to the fixing frame 113 through a torsion spring. After the contact plate 104 contacts the pressure piston plate 311, the contact plate 104 slides into the hook groove 312.

[0035] When the contact plate 104 produces an extrusion movement on the compressed piston plate 311, the rotating hook 114 will also contact the compressed piston plate 311 and rotate under the extrusion until the rotating hook 114 moves below the hook groove 312. Under the action of the torsion spring, the rotating hook 114 is reset and extends into the electromagnet 112. After the new battery pack is pushed onto the battery placement plate 303, the telescopic arm 102 needs to be reset. Under the traction of the electric push rod 116, the telescopic arm 102 is gradually reset. Since the contact plate 104 is hooked in the hook groove 312, the contact plate 104 will hook the compressed piston plate 311 and slide outward. Through the pressure conduction of the oil, the movable piston 313 is gradually retracted into the second piston cylinder 309, and the friction block 314 is used to rub the bottom of the battery pack to help the battery pack be completely connected to the wire to prevent the wire connection from being unstable.

[0036] A limiting frame 304 is fixedly connected to the battery placement plate 303, and a back fixing plate 305 is fixedly connected to the top end of the battery placement plate 303. A slot for placing the battery pack wires is opened on the back fixing plate 305, and an elastic wire clamping block 306 is fixedly connected to the side of the back fixing plate 305. The side of the back fixing plate 305 corresponding to the position of the wire slot is fixedly connected to the limiting shell 307 by bolts.

[0037] When the energy storage cabinet 3 is assembled as a whole, the battery placement plate 303 is installed on the internal bracket of the cabinet body 301, and the limit frame 304 helps to fix the position of the battery pack. At the same time, the cable part of the battery pack's wire needs to be clipped onto the elastic clamping block 306, and then the connector of the wire is placed in the slot of the back fixing plate 305, and then the limit shell 307 is fixed with bolts, so that the limit shell 307 limits the connector part of the wire, so that when the battery pack slides outward from the battery placement plate 303, the wire can stay on the back side of the back fixing plate 305, which is convenient for the battery pack to disconnect from it. When the battery pack is pushed onto the battery placement plate 303, the position of the wire remains relatively unchanged, which is also convenient for the battery pack to be connected to it.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
