Description

Technical Field

[0001] The present invention relates to the technical field of power transmission base application, and in particular to an energy storage base based on solar photovoltaic components. Background Art

[0002] The power transmission base plays a role in supporting and fixing the solar panels on the one hand, and storing electric energy in the photovoltaic energy storage system on the other hand. The existing power transmission base for solar panel photovoltaic energy storage system still has many shortcomings. The existing power transmission base for solar panel photovoltaic energy storage system has high friction loss when working with the solar panel during use, and the cables used to transmit electric energy in the base are easily entangled with each other, and the stability of the cable power transmission is poor. When the solar panel encounters severe weather such as thunderstorms and strong winds, the base cannot provide shock-absorbing and buffering force for the solar panel, resulting in poor stability of the solar panel when working and a short service life of the solar energy and the base.

[0003] The currently disclosed Chinese patent CN201811040449.5 is a power transmission base for a solar panel photovoltaic energy storage system, including an upper pallet, a support seat, an inner pallet, a wire collection seat and a lower pallet, the support seat being vertically arranged in the middle of the bottom of the upper pallet, and the inner pallet being vertically installed at the bottom of the support seat, a lower pallet being arranged parallel to the lower inner pallet, and wire collection seats being installed at both ends between the inner pallet and the lower pallet, a wire reel being arranged in the wire collection seat, a first set of cylindrical sliding rods being arranged parallel to both ends of the support seat, and a buffer support frame being vertically arranged between the four corners of the bottom of the upper pallet and the inner pallet, a sleeve welding plate being welded to the bottom of the support seat, and a second set of cylindrical sliding rods being penetrated at both ends of the sleeve welding plate, the inner pallet and the lower pallet Shock-absorbing sleeve rods are provided through the four corners, a cylindrical bottom bolt is provided in the middle of the bottom of the sleeve welding plate, and a plug-in column is welded to the bottom of the bottom bolt, and a first spring sleeve is sleeved on the plug-in column, the four shock-absorbing sleeve rods are all cylindrical structures, and the shock-absorbing sleeve rods are sleeved with a second spring sleeve, several of the wire drums are provided with hollow cylindrical outer sleeves, and several inner sleeves are penetrated inside the outer sleeves, and several of the inner sleeves are sleeved with cables, four of the buffer support frames are provided with hollow cylindrical rings, and a cylindrical extension rod is penetrated above the inside of the ring, a third spring sleeve is provided at the bottom of the extension rod, an inner rubber ring is sleeved at the bottom of the extension rod, and an outer rubber ring matching the inner rubber ring is provided inside the ring.

[0004] According to the above patent, the patent prevents the cables from getting entangled with each other by enclosing the cables in several inner sleeves in the through-pipe grooves for power supply. However, this method cannot solve the problem of cable entanglement. For the cable parts connected to the solar panels, since the cables are generally long and in a loose state, they are easily entangled with adjacent cables under the influence of strong winds, resulting in unstable energy storage. Therefore, there is a need for an energy storage base that can position the loose cables. Summary of the invention

[0047] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] See also Figure 1-Figure 5As shown, an energy storage base based on a solar photovoltaic assembly includes a support base 1 and a solar panel 2 arranged thereon, an energy storage device 3 is arranged on the support base 1, a cable 4 is connected between the solar panel 2 and the energy storage device 3, and a cable collection drum 11 for collecting the cable 4 is also arranged on the support base 1, and the outer wall of the cable collection drum 11 has a pipe sleeve 111 for the cable 4 to pass through, and a line fixing mechanism 5 is arranged on the support base 1 to prevent the connected adjacent cables 4 from being entangled, and the line fixing mechanism 5 has a first tensioning wheel 51 and a second tensioning wheel 52. The tension wheel 52, the first tension wheel 51 is arranged on the support base 1, the second tension wheel 52 is arranged on the solar panel 2, the second tension wheel 52 is located above the first tension wheel 51, one end of the cable 4 is connected to the energy storage device 3, and the other end of the cable 4 bypasses the first tension wheel 51 from the outside to the inside and is bypassed from the bottom of the second tension wheel 52 to connect with the solar panel 2, the first tension wheel 51 can move along the surface of the support base 1, and the support base 1 is provided with a tensioning drive mechanism 53 for driving the first tension wheel 51 to move.

[0049] When the solar panel 2 is used for heat absorption, the support base 1 is installed at the specified position, and then the solar panel 2 is installed on the support base 1. An energy storage device 3 is provided on the support base 1. The energy storage device 3 and the solar panel 2 are connected by a cable 4 to facilitate energy storage. The cable 4 is connected to the energy storage device 3 by passing through the pipe sleeve 111 on the hub 11 to ensure that the connection between the cable 4 and the energy storage device 3 is in a stable state to avoid disconnection. Since the cable 4 is in a loose state after connection, it is easy to cause entanglement between adjacent cables 4 when encountering strong winds, resulting in poor stability in power transmission. At this time, When connecting the cable 4, one end of the cable 4 is connected to the energy storage device 3, and the other end of the cable 4 is connected to the solar panel 2 by passing through the first tensioning wheel 51 and the second tensioning wheel 52 in turn, and then the first tensioning wheel 51 is driven to move by the tensioning drive mechanism 53, so that the cable 4 is in a state of being tightened by the first tensioning wheel 51 on the second tensioning wheel 52. There are multiple groups of first tensioning wheels 51 and second tensioning wheels 52, and each cable 4 corresponds to the first tensioning wheel 51 and the second tensioning wheel 52 in one group, so as to avoid the entanglement between the cables 4 and the cables 4. Under the influence of strong wind, the cable 4 still maintains a stable connection, and effectively transmits electricity stably.

[0050] See also Figure 6 and Figure 7 As shown, a guide frame 54 for installing the first tensioning wheel 51 is provided on the support base 1, and a movable channel is provided on the guide frame 54. The first tensioning wheel 51 is slidably arranged in the movable channel. Two strip plates 541 extend outwardly in parallel on the guide frame 54, and the gap between the two strip plates 541 constitutes the movable channel.

[0051] When the first tensioning wheel 51 is driven to move by the tensioning driving mechanism 53, the first tensioning wheel 51 moves in the moving channel formed by the two strip plates 541 on the guide frame 54, and the first tensioning wheel 51 keeps moving along the surface of the supporting base 1. The first tensioning wheel 51 moves relative to the second tensioning wheel 52. Since the cable 4 passes around the first tensioning wheel 51 from the outside and then comes out from the bottom of the second tensioning wheel 52, the first tensioning wheel 51 gradually moves outward, prompting the cable 4 to be gradually tightened on the second tensioning wheel 52, thereby effectively ensuring the stability of the connection of the cable 4.

[0052] See also Figure 6 and Fig.10 As shown, a connecting frame 55 for installing a second tensioning wheel 52 is provided on the solar panel 2, and the second tensioning wheel 52 can move on the connecting frame 55. A sliding opening 551 for the second tensioning wheel 52 to move is provided on the connecting frame 55. The movement direction of the second tensioning wheel 52 is parallel to the movement direction of the first tensioning wheel 51, and a buffer spring 552 is also connected between the second tensioning wheel 52 and the connecting frame 55.

[0053] When the cable 4 is gradually tightened, the cable 4 is squeezed on the second tensioning wheel 52. Since the second tensioning wheel 52 is slidably set in the slide 551 on the connecting frame 55, and a buffer spring 552 is connected between the second tensioning wheel 52 and the connecting frame 55, the second tensioning wheel 52 will move outward in the slide 551 after being squeezed by the cable 4, and the buffer spring 552 is in a stretched state, which has a buffering effect on the cable 4 tightened on the second tensioning wheel 52, thereby preventing the cable 4 from being squeezed on the surface of the second tensioning wheel 52 and causing wear. When the first tensioning wheel 51 relaxes the cable 4, it only needs to move back, the buffer spring 552 returns to a normal state, and the cable 4 also changes from a tightened state to a loose state, so as to facilitate the replacement or maintenance of the cable 4.

[0054] See also Figure 6-Figure 8 As shown, the tensioning drive mechanism 53 is provided with a ring 531 and a slide 532. The ring 531 is rotatably sleeved on the wire hub 11. A bearing 5311 is connected between the ring 531 and the wire hub 11. The slide 532 is slidably set in the moving channel. The first tensioning wheel 51 is rotatably set on the slide 532. A pushing member 533 is connected between the slide 532 and the ring 531. A rotating driver 534 is provided on the support base 1 for driving the ring 531 to rotate. When the ring 531 rotates, the slide 532 is in a state of being pulled by the pushing member 533 to slide in the moving channel.

[0055] When the tensioning drive mechanism 53 drives the first tensioning wheel 51 to move, the rotation driver 534 drives the ring 531 to rotate. As the ring 531 rotates, the push-pull member moves with the ring 531 due to the connection between the slide 532 and the ring 531 through the push-pull member. According to the rotation of the ring 531 in different directions, the push-pull member pushes the slide 532 in different directions, thereby prompting the slide 532 to drive the first tensioning wheel 51 to move in the moving channel.

[0056] See also Figure 7 and Figure 8 As shown, the pushing member 533 is provided with a connecting rod 5331, and the two ends of the connecting rod 5331 are respectively hinged to the sliding seat 532 and the ring 531, and both ends of the connecting rod 5331 have hinge holes. The ring 531 has a first hinge part 5312 hinged to the end of the connecting rod 5331, and the sliding seat 532 has a second hinge part 5321 hinged to the end of the connecting rod 5331.

[0057] The circular ring 531 and the sliding seat 532 are connected by a pushing member 533. Since the pushing member 533 is provided with a connecting rod 5331, and both ends of the connecting rod 5331 are hinged to the circular ring 531 and the sliding seat 532, as the circular ring 531 rotates, the connecting rod 5331 pushes and pulls the sliding seat 532, thereby realizing the push-pull movement of the connecting rod 5331 on the sliding seat 532.

[0058] See also Figure 7 As shown, the rotary driver 534 is provided with a ring gear 5341 and a gear 5342 . The ring gear 5341 is coaxial with the ring 531 and fixedly connected. The gear 5342 is meshed with the ring gear 5341 . A rotary motor 5343 is provided on the support base 1 for driving the gear 5342 to rotate.

[0059] When the rotary driver 534 drives the ring 531 to rotate, the rotary motor 5343 drives the gear 5342 to rotate. Since the gear 5342 is meshed with the ring gear 5341 , the gear 5342 drives the ring gear 5341 to rotate, thereby driving the ring 531 to rotate.

[0060] See also Fig. 9 As shown, the inner wall of the sleeve 111 on the hub 11 has a lining pad 112 for protecting the surface of the cable 4 .

[0061] When the cable 4 passes through the sleeve 111 and is connected to the energy accumulator 3, the sleeve 111 has an inner lining cushion 112, so the connection between the cable 4 and the energy accumulator 3 is protected. When the cable 4 is gradually tightened, the surface of the cable 4 in the sleeve 111 is buffered under the protection of the inner lining cushion 112, avoiding the phenomenon of the cable 4 being squeezed and sunken by the contact with the edge of the sleeve 111, thereby effectively protecting the connection between the cable 4 and the energy accumulator 3.

[0062] See also Figure 5 As shown, a shock-absorbing connector 6 is provided between the solar panel 2 and the cable hub 11 .

[0063] When the solar panel 2 is connected to the supporting base 1, the shock-absorbing connector 6 is installed in the hub 11 to connect to the solar panel 2. In bad weather, the solar panel 2 can obtain a shock-absorbing effect. Compared with the fixed installation of the solar panel 2 and the supporting base 1, it is more effective in protecting the solar panel 2, which is beneficial to the stability of the solar panel 2 during operation and increases the service life of the solar panel 2.

[0064] See also Figure 5 and Fig. 9 As shown, the shock-absorbing connecting member 6 is provided with a support column 61, one end of the support column 61 is fixedly connected to the solar panel 2, and the other end of the support column 61 is coaxially inserted in the hub 11, and the lower end of the support column 61 is extended with an insertion rod 611 whose diameter is smaller than the inner diameter of the hub 11, and the lower end of the hub 11 is provided with a supporting end plate 62 for the end of the insertion rod 611 to abut against it, and a shock-absorbing spring 612 mounted on the insertion rod 611 is connected between the lower end of the support column 61 and the support end plate 62.

[0065] When the solar panel 2 is installed with the shock-absorbing connector 6, a support column 61 is installed on the solar panel 2. By inserting the support column 61 into the hub 11 and connecting it to the support end plate 62 through the shock-absorbing spring 612, under normal weather conditions, the insertion rod 611 on the support column 61 is in a state of being supported on the support end plate 62, and the solar panel 2 is in a fixed state relative to the support base 1. When the weather is bad, the solar panel 2 is affected by the environment, and the support column 61 is in an active state relative to the support base 1 in the hub 11. The shock-absorbing spring 612 has a shock-absorbing effect on the movement of the support column 61, thereby having a shock-absorbing effect on the solar panel 2. In addition, since the connecting frame 55 installed on the second tensioning wheel 52 is fixedly connected to the support column 61, when the support column 61 moves up and down, the connecting frame 55 will also drive the second tensioning wheel 52 to move. The tensioning wheel 52 moves up and down, the second tensioning wheel 52 is in a fixed state, and the cable 4 is in a taut state. When the solar panel 2 moves upward, the portion of the cable 4 connected to it also needs to move upward. At this time, the second tensioning wheel 52 is in a fixed state, which blocks the cable 4, thereby causing the connection between the cable 4 and the solar panel 2 to be disconnected. Therefore, the synchronous movement of the second tensioning wheel 52 and the support column 61, after the second tensioning wheel 52 moves upward, has a relaxing effect on the cable 4, prompting the cable 4 to be squeezed on the second tensioning wheel 52 while moving up with the solar panel 2, thereby keeping the cable 4 in a stable taut state under the shock absorption state, thereby achieving both shock absorption of the solar panel 2 and stable power transmission of the cable 4, thereby avoiding entanglement between adjacent cables 4 under the influence of bad weather.

[0066] See also Fig. 9 As shown, a guide sleeve 63 which is sleeved on the support column 61 is fixedly provided on the top of the cable hub 11 . When the solar panel 2 is affected by strong winds, the support column 61 is in a state of reciprocating sliding in the guide sleeve 63 .

[0067] The guide sleeve 63 guides the support column 61 to ensure that the support column 61 is always in a vertical state, so that the solar panel 2 remains stable in a shock-absorbing state.

[0068] In this embodiment, the cable 4 is connected to the solar panel 2 and the energy storage device 3 by bypassing the first tensioning wheel 51 and the second tensioning wheel 52. After the second tensioning wheel 52 is moved by the tensioning drive mechanism 53, the cable 4 is tightened on the second tensioning wheel 52 by the first tensioning wheel 51, thereby avoiding the situation where the cable 4 is in a loose state and the adjacent cables 4 are entangled in strong winds, thereby improving the stability of power transmission by the cable 4.

[0069] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
