Description

Technical Field

[0001] This utility model relates to the field of solar energy, and in particular to an energy storage assist device and photovoltaic equipment. Background Technology

[0002] In industries involving rotational transmission around an axis, such as photovoltaic tracking, radar, and robotic arms, traditional mechanical transmission systems generally suffer from high energy consumption and high drive costs. These systems typically rely on motors to provide driving force to overcome the load's gravity. Especially in heavy-load scenarios, high-power motors are required to meet torque demands, leading to a significant increase in energy consumption and higher system operating costs.

[0003] Taking photovoltaic (PV) tracking systems as an example, as the size of PV panels increases, their weight also increases. In existing technologies, the rotation of PV panels mainly relies on direct motor drive or power transmission through a reduction gear mechanism. However, when dealing with heavy PV panels, this driving method not only requires a more powerful motor but also consumes additional electrical energy to maintain the dynamic balance of the PV panels, severely impacting power generation efficiency and the overall economic viability of the system. Furthermore, in cloudy or rainy weather or under weak sunlight, the motor still needs to continuously supply power to maintain the tracking posture of the PV panels, further exacerbating energy waste.

[0004] Similar problems are also prevalent in applications such as radar antenna pitch adjustment and robotic arm end effector rotation. Traditional transmission structures lack an effective mechanism for balancing load gravity, causing the drive system to operate under high load for extended periods, affecting equipment lifespan and increasing maintenance frequency.

[0005] Therefore, there is an urgent need to design a device that can reduce drive energy consumption and decrease dependence on motor power in order to improve system energy efficiency and achieve energy saving and cost reduction. Utility Model Content

[0007] As a first aspect of this utility model, an energy storage and assist device is proposed, comprising:

[0008] The base consists of a main body and two first side plates. The main body is perpendicular to and fixedly connected to the first side plates. The main body is located between the two first side plates. The cross-section of the base is "I" shaped. The main body is provided with a first hinge position.

[0009] The energy storage unit includes a cam assembly, a first traction component, and a first elastic component;

[0010] The cam assembly is rotatably mounted on the base via the first hinge position;

[0011] The first elastic element is fixedly connected to the first side plate;

[0012] One end of the first traction member is fixedly connected to the cam assembly, and the other end is fixedly connected to the first elastic member;

[0013] It also includes two second side plates, which are parallel to the main body and fixedly connected to the first side plate.

[0014] Furthermore, the base and / or the second side plate are provided with reinforcing ribs.

[0015] Furthermore, the second side plate is provided with a second hinge position that cooperates with the first hinge position, and the reinforcing rib is provided at the first hinge position and / or the second hinge position.

[0016] Furthermore, the cam assembly includes an output wheel, and the energy storage unit also includes a third traction member, one end of which is fixedly connected to the output wheel, and the other end of which is fixedly connected to an external component.

[0017] Furthermore, the cam assembly also includes a first cam and a second cam, wherein the first cam, the second cam, and the output wheel are integrally formed;

[0018] The energy storage unit also includes a second traction component and a second elastic component;

[0019] One end of the first traction member is fixedly connected to the first cam, and the other end is fixedly connected to the first elastic member;

[0020] One end of the second traction member is fixedly connected to the second cam, and the other end is fixedly connected to the second elastic member;

[0021] The first elastic element and the second elastic element release their elastic potential energy in opposite directions;

[0022] Furthermore, the energy storage unit also includes a first guide wheel, which is disposed on the main body for guiding the first traction member and is located between the cam group and the first elastic member;

[0023] The energy storage unit also includes a second guide wheel, which is disposed on the main body for guiding the second traction member and is located between the cam group and the second elastic member.

[0024] Furthermore, the energy storage unit also includes a third guide wheel, which is disposed on the main body for guiding the third traction member and is located between the output wheel and the external component.

[0025] Furthermore, the energy storage unit is in two sets, and the two sets of energy storage units are symmetrically arranged.

[0026] Furthermore, the first elastic element is a helical spring, and the energy storage and assist device also includes a spring sleeve, which is used to accommodate the first elastic element and is fixedly connected to the first side plate.

[0027] As a second aspect of this utility model, a photovoltaic device is proposed, including the above-mentioned energy storage assist device, and also including a column, a drive shaft and a photovoltaic panel;

[0028] The fixed end of the drive shaft is fixedly connected to the column, and the output end is fixedly connected to the photovoltaic panel;

[0029] The energy storage assist device is connected to the drive shaft and is used to provide auxiliary torque to drive the photovoltaic panel to rotate around the drive shaft.

[0030] The beneficial effects of this utility model are as follows:

[0031] 1. The base adopts an "I"-shaped cross-section structure, consisting of a main body and first side plates vertically fixed to both sides. In this structure, the first elastic element is directly connected to the first side plate. When the energy storage assist device is in energy storage or release state, the elastic force generated by the elastic element is evenly transmitted to the entire base through the first side plate. The I-shaped cross-section structure can effectively resist the torque generated by the elastic element during compression or tension. This ensures the base maintains structural stability when subjected to energy storage-release cyclic loads, making it particularly suitable for scenarios requiring long-term operation, such as photovoltaic tracking systems, ensuring transmission accuracy and equipment lifespan.

[0032] 2. The main body and second side plate of the base are equipped with reinforcing ribs, which are concentrated near the first and second hinge positions. This targeted arrangement of the reinforcing ribs in the hinge area enhances the local load-bearing capacity of the connection area between the base and the cam assembly, effectively suppressing torsional deformation of the cam assembly under elastic force. This design improves the operational stability of the energy storage assist device under complex conditions such as wind load disturbances, while maintaining stable transmission efficiency during long-term use. It is particularly suitable for applications with high reliability requirements, such as outdoor photovoltaic tracking systems.

[0033] 2. The design of the first guide wheel reduces friction between the first traction component and other components in the energy storage and assist device during movement, thereby improving the smoothness of movement and reducing component wear.

[0034] 3. Two sets of symmetrically arranged energy storage units, with the first and second elastic elements releasing their elastic potential energy in opposite directions, form a symmetrical bidirectional assist structure. This design not only improves the load balancing capability of the energy storage assist device but also effectively counteracts the deflection torque caused by unilateral force, thereby enhancing the overall structural stability and reliability. Furthermore, the bidirectional assist structure with the additional second elastic element can significantly reduce the power demand of the drive motor and improve energy utilization efficiency in applications such as photovoltaic tracking systems.

[0035] 4. The one-piece molded first and second cams improve the integration of the energy storage and assist device, reduce the number of individual components, and optimize the overall structure of the energy storage and assist device.

[0036] 5. The first elastic element (second elastic element) is fixedly connected to the first side plate. The elastic element is installed near the base. The energy storage and assist device is an integral unit, making the overall structure of the energy storage and assist device more compact, integrated, and easy to install.

[0037] 6. The first elastic element is a helical spring, and a spring sleeve is installed on the outside of the helical spring to protect the critical spring part in the energy storage and assist device, preventing it from being damaged or interfered with, and improving system stability. Furthermore, the helical spring is installed in a compressed manner inside the spring sleeve, which reduces the movement space required by the spring compared to a tension spring, thereby improving the integration and space utilization of the energy storage and assist device.

[0056] The present invention will be further described in detail below with reference to the accompanying drawings.

[0057] As the first aspect of this specific embodiment, such as Figures 1 to 6 As shown, an energy storage assist device 1 is proposed, including a base 11, an energy storage unit, and second side plates 18. The base 11 consists of a main body 111 and two first side plates 112. The main body 111 is perpendicular to and fixedly connected to the first side plates 112, and the main body 111 is located between the two first side plates 112. The cross-section of the base 11 is "I"-shaped, and the main body 111 has a first hinge position. The energy storage unit includes a cam assembly 12, a first traction member 131, and a first elastic member 141. The cam assembly 12 is rotatably mounted on the base 11 through the first hinge position. The first elastic member 141 is fixedly connected to the first side plates 112. One end of the first traction member 131 is fixedly connected to the cam assembly 12, and the other end is fixedly connected to the first elastic member 141. It also includes two second side plates 18, which are parallel to the main body 111 and fixedly connected to the first side plates 112.

[0058] It should be noted that, in cases such as Figure 6In the schematic diagram shown, the base 11 is viewed from a perspective similar to its cross-section. The base 11 adopts an "I"-shaped cross-section design, consisting of a main body 111 and first side plates 112 vertically fixed to both sides. In this structure, the first elastic element 141 is directly connected to the first side plate 112. When the energy storage assist device 1 is in an energy storage or release state, the elastic force generated by the elastic element is evenly transmitted to the entire base 11 through the first side plate 112. The I-shaped cross-section structure has a high moment of inertia, effectively resisting the torque generated by the elastic element during compression or tension. The main body 111, as the central component, is supported by the first side plates 112, which bear tensile and compressive stresses respectively, forming a closed force flow path and significantly optimizing stress distribution. This design enables the base 11 to maintain structural stability when subjected to energy storage-release cyclic loads, making it particularly suitable for scenarios requiring long-term operation, such as photovoltaic tracking systems, ensuring transmission accuracy and equipment lifespan.

[0059] In such Figure 5 In some embodiments shown, the base 11 and / or the second side plate 18 are provided with reinforcing ribs. Further, the second side plate 18 is provided with a second hinge position 181 that mates with the first hinge position. The first and second hinge positions 181 are used to mount the cam assembly 12, allowing the cam assembly 12 to achieve a rotatable connection with the base 11. The reinforcing ribs are located at the first and / or second hinge positions 181. The targeted arrangement of the reinforcing ribs in the hinge position area enhances the local load-bearing capacity of the connection area between the base 11 and the cam assembly 12, effectively suppressing the torsional deformation of the cam assembly 12 under elastic force. This design improves the operational stability of the energy storage assist device 1 under complex conditions such as wind load disturbances, while maintaining stable transmission efficiency during long-term use. It is particularly suitable for applications with high reliability requirements, such as outdoor photovoltaic tracking systems.

[0060] In some embodiments, the cam assembly 12 includes an output wheel 123, and the energy storage unit also includes a third traction member, one end of which is fixedly connected to the output wheel 123 and the other end of which is fixedly connected to an external component.

[0061] In some embodiments, the cam assembly 12 further includes a first cam 121 and a second cam 122. The first cam 121, the second cam 122, and the output wheel 123 are integrally formed. The integrally formed first cam 121 and second cam 122 improve the integration of the energy storage assist device 1, reduce the number of individual components, and optimize the overall structure of the energy storage assist device 1. The energy storage unit also includes a second traction member 132 and a second elastic member 142; one end of the first traction member 131 is fixedly connected to the first cam 121, and the other end is fixedly connected to the first elastic member 141; one end of the second traction member 132 is fixedly connected to the second cam 122, and the other end is fixedly connected to the second elastic member 142; as shown... Figure 2In the embodiment shown, the first elastic element 141 and the second elastic element 142 are disposed on both sides of the base 11. The elastic potential energy of the first elastic element 141 and the second elastic element 142 are released in opposite directions. The elastic elements on both sides can keep the energy storage and release device 1 in a balanced and stable state during energy storage or release.

[0062] exist Figure 2 In some embodiments shown, the energy storage unit further includes a first guide wheel 151, disposed on the main body 111, for guiding the first traction member 131, and located between the cam group 12 and the first elastic member 141; the energy storage unit further includes a second guide wheel 152, disposed on the main body 111, for guiding the second traction member 132, and located between the cam group 12 and the second elastic member 142.

[0063] In some embodiments, the energy storage unit further includes a third guide wheel 153, which is disposed on the main body 111 for guiding the third traction member and is located between the output wheel 123 and the external component.

[0064] In some implementations, there are two sets of energy storage units, arranged symmetrically. For example... Figure 2 In the illustrated embodiment, the two sets of energy storage units are symmetrically arranged with the centerline of the main body 111 as the line of symmetry. This design not only improves the load balancing capability of the energy storage assist device 1, but also effectively counteracts the deflection torque caused by unilateral force, thereby enhancing the stability and reliability of the overall structure. Furthermore, the bidirectional assist structure with the addition of a second elastic element 142 can significantly reduce the power demand of the drive motor and improve energy utilization efficiency in applications such as photovoltaic tracking systems.

[0065] In some embodiments, the first elastic element 141 is a helical spring, and the energy storage and assist device 1 further includes a spring sleeve 16, which is used to accommodate the first elastic element 141 and is fixedly connected to the first side plate 112.

[0066] A pusher is provided at the end of the spring sleeve 16 away from the first cam 121, and the first traction member 131 is fixedly connected to the first elastic member 141 through the pusher. The first elastic member 141 is a helical spring, and the spring sleeve 16 is provided on the outside of the helical spring to protect the critical spring part in the energy storage assist device 1, prevent it from being damaged or interfered with, and improve the stability of the system.

[0067] In some embodiments, the first traction member 131, when subjected to force, drives the pusher member to move along the extension and retraction direction of the helical spring to compress the helical spring. The helical spring is arranged in a compressed manner within the spring sleeve 16, which, compared to a tension spring, reduces the required movement space of the spring and improves the integration and space utilization of the energy storage and assist device 1.

[0068] The energy storage and assist device 1 has an energy storage state and an energy release state. Taking the first cam 121 as an example: when the first cam 121 is rotated by an external force, it winds around the first traction member 131, causing the first elastic member 141 to deform until the energy storage and assist device 1 reaches a fully stored state. When the energy storage and assist device 1 is in the energy release state, the first cam 121 rotates in the opposite direction, and the first elastic member 141 releases its elastic potential energy.

[0069] In some embodiments, the first traction member 131 and / or the second traction member 132 is a plate chain. The plate chain is composed of metal plates hinged to pins, possessing high tensile strength and good bending resistance. Its plate structure can withstand large-angle deflections and is not prone to torsional fatigue fracture; it has good wear resistance, long service life, and low maintenance costs. In the energy storage assist device 1, the plate chain, as the first traction member 131 (second traction member 132), can effectively replace the wire rope. Its hinged structure adapts to non-collinear transmission paths, ensuring smooth force transmission even when the guide wheel is perpendicular to the axis of the cam assembly 12, avoiding torsional fracture. Compared to wire rope, the plate chain has higher transmission efficiency, stronger fatigue resistance, and stable operation in high-frequency energy storage-release cycles, significantly improving the reliability and service life of the device.

[0070] To improve transmission efficiency, the circumferential profiles of the first cam 121 and the second cam 122 that engage with the plate chain are designed as polygonal structures. These polygonal profiles form intermittent meshing transmissions with the links of the plate chain, effectively avoiding energy loss caused by sliding friction between the traditional circular cam and the chain. In other embodiments, the circumferential profiles of the first cam 121 and the second cam 122 that engage with the plate chain are designed as chain teeth, and the chains of the first traction member 131 and the second traction member 132 are roller chains, which also improves transmission stability.

[0071] In such Figure 1 In some embodiments shown, the energy storage assist device 1 is further provided with a protective housing 17, which includes an upper cover 171 and a lower cover 172. The housing 17 completely encloses the energy storage assist device 1 to prevent the external environment from affecting the internal components of the energy storage assist device 1.

[0072] As a second aspect of this embodiment, a photovoltaic device is proposed, including the aforementioned energy storage assist device 1, and further including a column 4, a drive shaft 2, and a photovoltaic panel 3. It should be noted that the external component connected to the third traction member is the drive shaft 2 in the photovoltaic device. The fixed end of the drive shaft 2 is fixedly connected to the column 4, and the output end is fixedly connected to the photovoltaic panel 3. The energy storage assist device 1 is driven by the drive shaft 2, providing auxiliary torque to drive the photovoltaic panel 3 to rotate around the drive shaft 2.

[0073] like Figure 7In the embodiment of the photovoltaic device shown, the energy storage assist device 1 is placed near the transmission shaft 2, which can reduce the distance of the transmission path, improve the transmission efficiency, and thus improve the overall effect of energy storage and release.
