Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and specifically relates to an installation structure and an installation method for a power transmission and distribution busbar of a photovoltaic power generation device. Background Art

[0002] A busbar is an enclosed metal device composed of copper or aluminum busbars, used to distribute relatively large power to each component of a decentralized system. It has increasingly replaced wires and cables in indoor low-voltage power transmission main line engineering projects. Busbars are used for power transmission during the power transmission and distribution of photovoltaic power generation devices. At the same time, busbars are generally hoisted on the roof and do not occupy the ground area.

[0003] Since the busbar needs to be fixed by a hoisting bracket during installation and multiple busbars need to be connected, it is difficult to fix the connected busbars on the hoisting bracket after connection on the ground. After the position of the hoisting bracket is fixed, multiple busbars need to be installed on the hoisting bracket in sequence and adjacent busbars need to be connected.

[0004] When connecting adjacent busbars of a compact busbar, a connector needs to be tightly inserted between the two side busbars, and then the two side busbars are fixed using a sealing plate. When inserting the connector, the distance between the two side busbars needs to be adjusted more precisely. After placing the busbar on the hoisting bracket, generally, manual adjustment of the position of the busbar is required at a relatively high position. If the busbar is directly dragged on the hoisting bracket, on the one hand, the manual labor intensity is relatively large, and on the other hand, it may cause wear on the outer side of the busbar, and even cause deformation of the hoisting bracket, resulting in a change in the predetermined installation position, thereby affecting the installation of the busbar. Therefore, the present application proposes an installation structure and an installation method for a power transmission and distribution busbar of a photovoltaic power generation device.

[0044] Step 6: After the position of the busbar is fixed, adjacent busbars can be connected at this time, and then the auxiliary unit is removed.

[0045] The present invention discloses an installation structure of a power transmission and distribution busbar of a photovoltaic power generation device and its installation method, and the beneficial effects thereof are as follows:

[0046] 1. For the installation structure of the power transmission and distribution busbar of this photovoltaic power generation device, the driving component is used to make the side clamping blocks on both sides move towards the busbar until the side limiting balls on both sides squeeze the two sides of the busbar, achieving a more accurate centering and positioning of the busbar. The bottom limiting balls and side limiting balls enable the busbar to move along the axial direction, thereby facilitating the adjustment of the spacing between adjacent busbars. The driving component is continuously used to make the side clamping blocks on both sides move towards the busbar until the side clamping blocks on both sides abut against the outer side of the busbar, thereby clamping and positioning the busbar. At the same time, the driving component can drive multiple bottom support blocks to move upward until the multiple bottom support blocks fit against the bottom of the busbar, increasing the force-bearing area at the bottom of the busbar.

[0047] 2. For the installation structure of the power transmission and distribution busbar of this photovoltaic power generation device, when the driving component works, it can drive the side clamping blocks on both sides to move towards each other, so that the side limiting balls can move towards the busbar until the side limiting balls fit against the busbar. At the same time, under the action of the limiting spring, the limiting balls can tightly abut against the busbar. Since the bottom of the busbar is in contact with the bottom limiting balls and the rolling friction between the two is small, the side limiting balls can push the busbar to perform centering adjustment under the action of the limiting spring. At this time, the spacing between adjacent busbars can be adjusted. After the adjustment is completed, the driving component is used again to make the side clamping blocks continue to move towards the busbar, causing the limiting spring to be further compressed until the side limiting balls completely enter the movable groove. At this time, the side clamping blocks fit against the two sides of the busbar, thereby playing a stable clamping and fixing role for the busbar.

[0048] 3. For the installation structure of the power transmission and distribution busbar of this photovoltaic power generation device, when the bidirectional threaded rod is rotated, the two nut blocks symmetrically arranged on the outer side of the bidirectional threaded rod can move towards each other, thereby driving the side clamping blocks to move accordingly. At the same time, when the limiting spring is compressed and the side limiting balls enter the movable groove, the nut block contacts the end of the movable bar, thereby being able to push the movable bar to move horizontally in the guiding bar. Since the inclined downward end of the pressing bar abuts against the support frame, the support frame is driven to move upward accordingly, so that multiple bottom support blocks move towards the bottom of the busbar. When the side clamping blocks fit against the two sides of the busbar, the multiple bottom support blocks fit against the bottom of the busbar. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] By providing an installation structure and installation method for a power transmission and distribution busbar of a photovoltaic power generation device, the embodiments of the present application solve the problem that after the busbar is placed on the hoisting bracket, it generally requires manual adjustment of the position of the busbar at a relatively high position.

At the same time, the transmission assembly 14 can drive a plurality of bottom support blocks 122 to move upward until the plurality of bottom support blocks 122 are in contact with the bottom of the busbar, increasing the force-bearing area at the bottom of the busbar.

[0063] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0064] Embodiment 1

[0065] The embodiments of the present invention disclose an installation structure and installation method for a power transmission and distribution busbar of a photovoltaic power generation device.

[0066] As shown in the attached Figures 1-9 figures, it includes:

[0067] The installation unit 1, which includes:

[0068] The bearing assembly 11;

[0069] The bottom support assembly 12, which is arranged on the bearing assembly 11 and includes:

[0070] Bottom limiting ball 121, which supports the bottom of the bus duct and assists the bus duct in position adjustment;

[0071] A bottom support block 122, which provides bottom support for the bus duct after it is fixed;

[0072] The side limit assembly 13 is symmetrically arranged on the bearing assembly 11 and includes:

[0073] A side clamping block 131 is used to clamp and position the side of the bus duct;

[0074] Side limiting balls 132 are used to squeeze and position the two sides of the bus duct and assist the bus duct in position adjustment;

[0075] The transmission assembly 14 is disposed inside the bearing assembly 11, and the transmission assembly 14 is used to drive the bottom support assembly 12 and the side limit assembly 13 to transmit;

[0076] The auxiliary unit 2 is installed on the outside of the bearing assembly 11 , and the auxiliary unit 2 can cooperate with the bottom support assembly 12 and the side limit assembly 13 to dock the adjacent bus ducts.

[0077] First, place the bus duct on the bearing assembly 11, and make the bus duct fit with the bottom limiting ball 121, and use the bottom limiting ball 121 to manually push the bus duct to be placed in the center; at this time, use the transmission assembly 14 to move the side clamping blocks 131 on both sides toward the bus duct until the side limiting balls 132 on both sides squeeze the two sides of the bus duct, so as to more accurately center the bus duct; install the auxiliary unit 2 on the outside of the bearing assembly 11, and make the auxiliary unit 2 stably support the bus duct so that the bus duct cannot be flipped; use the bottom limiting ball 121 and the side limiting The ball 132 enables the bus duct to move along the axial direction, thereby facilitating the adjustment of the spacing between adjacent bus ducts; the transmission assembly 14 is continued to be used to move the side clamping blocks 131 on both sides toward the bus duct until the side clamping blocks 131 on both sides are against the outer side of the bus duct, thereby clamping and positioning the bus duct; at the same time, the transmission assembly 14 can drive multiple bottom support blocks 122 to move upward until the multiple bottom support blocks 122 are in contact with the bottom of the bus duct, thereby increasing the force-bearing area of ​​the bottom of the bus duct; after the position of the bus duct is fixed, the adjacent bus ducts can be connected at this time, and then the auxiliary unit 2 can be removed.

[0078] Particularly disclosed, the bearing assembly 11 comprises:

[0079] The load-bearing profile 111 is provided with cavities extending through the two ends of the axis;

[0080] The suspension rod 112 is symmetrically installed at both ends of the load-bearing profile 111, and the top of the suspension rod 112 is fixedly installed on the ceiling of the photovoltaic power generation plant through embedded bolts;

[0081] The positioning strip 113 is fixedly installed at the bottom of the load-bearing profile 111 and is used to assist in the installation of the unit 2.

[0082] Furthermore, a support frame 123 is arranged in the inner cavity of the load-bearing profile 111, and the top of the support frame 123 is fixedly connected to a plurality of bottom support blocks 122. A plurality of moving grooves 124 are formed on the outer side of the load-bearing profile 111, and a moving strip 125 is slidably arranged in the plurality of moving grooves 124, and the ends of the plurality of moving strips 125 are fixedly connected to the support frame 123.

[0083] The support frame 123 is used to form an integral body of the plurality of bottom support blocks 122. At the same time, the moving grooves 124 and the moving strips 125 are arranged to enable the support frame 123 to only move vertically, thereby limiting the moving direction and distance of the plurality of bottom support blocks 122.

[0084] Furthermore, a clamping groove 134 is formed above the load-bearing profile 111. The bottom of the side clamping block 131 is slidably arranged on the inner wall of the clamping groove 134, and a plurality of accommodating cylinders 133 are installed on the outer side of the side clamping block 131. An activity groove 135 is formed between the inside of the accommodating cylinder 133 and the inside of the side clamping block 131. The end of the side limiting ball 132 is slidably arranged in the activity groove 135, and a limiting spring 136 is fixedly installed between the end of the side limiting ball 132 and the inner wall of the activity groove 135. The end of the side limiting ball 132 is also fixedly connected to a guide rod 137, and the end of the guide rod 137 passes through the end of the accommodating cylinder 133 and extends outward.

[0085] Through the provided clamping groove 134, the side clamping block 131 can move stably. When the transmission component 14 operates, it can drive the side clamping blocks 131 on both sides to move towards each other, thereby enabling the side limit balls 132 to move towards the busbar groove until the side limit balls 132 are in contact with the busbar groove. At the same time, under the action of the limit spring 136, the side limit balls 132 can be tightly pressed against the busbar groove. Since the bottom of the busbar groove is in contact with the bottom limit ball 121 and the rolling friction between the two is small, under the action of the limit spring 136, the side limit balls 132 can push the busbar groove for centering adjustment. At this time, the spacing between adjacent busbar grooves can be adjusted. After the adjustment is completed, the transmission component 14 is used again to make the side clamping block 131 continue to move towards the busbar groove, causing the limit spring 136 to be further compressed until the side limit balls 132 completely enter the movable groove 135. At this time, the side clamping block 131 is in contact with both sides of the busbar groove, thereby playing a stable clamping and fixing role on the busbar groove.

[0086] Specifically disclosed, the transmission component 14 includes:

[0087] A bidirectional threaded rod 141, which is rotationally connected to the inner cavity of the bearing profile 111 through a bearing seat, and rotational grooves 1411 are provided at both ends of the bidirectional threaded rod 141;

[0088] Nut blocks 142, two nut blocks 142 are symmetrically arranged on the outside of the bidirectional threaded rod 141, and the two nut blocks 142 are threadedly connected to the bidirectional threaded rod 141. The top of the nut block 142 is fixedly connected to the side clamping block 131;

[0089] A guide bar 143, which is fixedly connected to the inner cavity of the bearing profile 111;

[0090] A movable bar 144, which is slidably connected to the inside of the guide bar 143, and the movable bar 144 is located on the side of the nut block 142;

[0091] An extrusion bar 145, which is fixedly connected to the other end of the movable bar 144. The extrusion bar 145 is inclined, and the inclined downward end of the extrusion bar 145 abuts against the support frame 123;

[0092] A bearing bar 146, which is fixedly connected to the inclined downward end of the extrusion bar 145 and is in contact with the bottom of the support frame 123.

[0093] When rotating the bidirectional threaded rod 141, the two nut blocks 142 symmetrically arranged on the outer side of the bidirectional threaded rod 141 can move towards each other, thereby driving the side clamping blocks 131 to move accordingly. At the same time, when the limiting spring 136 is compressed and the side limiting ball 132 enters the movable groove 135, the nut block 142 contacts the end of the movable bar 144, and then can push the movable bar 144 to move horizontally in the guiding bar 143. Since the inclined downward end of the pressing bar 145 abuts against the support frame 123, the support frame 123 is driven to move upward accordingly, and then a plurality of bottom support blocks 122 move towards the bottom of the busbar chute. While the side clamping blocks 131 are attached to both sides of the busbar chute, a plurality of bottom support blocks 122 are attached to the bottom of the busbar chute, increasing the force-bearing area at the bottom of the busbar chute, and thus can effectively protect the bottom of the busbar chute, avoiding damage to the bottom of the busbar chute due to too small a force-bearing area when vibration occurs.

[0094] Further, the joints of the pressing bar 145 and the bearing bar 146 and the bottom corners of the support frame 123 are all rounded. And an activity block is fixedly connected to the outer side of the movable bar 144, and the activity block is slidably connected inside the guiding bar 143. A positioning spring 147 is movably sleeved on the outer side of the movable bar 144, and both ends of the positioning spring 147 are fixedly connected to the inner wall of the movable bar 144 and the guiding bar 143 respectively.

[0095] Since the joints of the pressing bar 145 and the bearing bar 146 and the bottom corners of the support frame 123 are all rounded, it is further made easier for the pressing bar 145 to push the support frame 123 upward. By using the provided positioning spring 147 and the activity block, the position of the movable bar 144 is limited when the nut block 142 does not push the movable bar 144 to move.

[0096] It should be emphasized that both the bottom limiting ball 121 and the side limiting ball 132 are composed of a spherical seat and a ball rotatably arranged inside the spherical seat. The ball can roll 360 degrees relative to the spherical seat, and thus when the busbar chute contacts the ball, the friction force is greatly reduced, facilitating the movement of the position of the busbar chute.

[0097] An installation method for an installation structure of a power transmission and distribution busbar chute of a photovoltaic power generation device, the installation method includes the following steps:

[0098] Step 1: First, place the busbar chute on the bearing assembly 11, and make the busbar chute fit with the bottom limiting ball 121. By using the bottom limiting ball 121, an operator can push the busbar chute to be placed in the center.

[0099] Step 2: At this time, use the transmission assembly 14 to move the side clamping blocks 131 on both sides towards the busbar groove until the side limit balls 132 on both sides squeeze the two sides of the busbar groove, achieving more precise centering and positioning of the busbar groove.

[0100] Step 3: Install the auxiliary unit 2 on the outside of the bearing assembly 11, and make the auxiliary unit 2 stably support the busbar groove so that the busbar groove cannot flip.

[0101] Step 4: Use the bottom limit balls 121 and the side limit balls 132 to enable the busbar groove to move along the axial direction, thereby facilitating the adjustment of the distance between adjacent busbar grooves.

[0102] Step 5: Continue to use the transmission assembly 14 to move the side clamping blocks 131 on both sides towards the busbar groove until the side clamping blocks 131 on both sides abut against the outside of the busbar groove, thereby clamping and positioning the busbar groove. At the same time, the transmission assembly 14 can drive multiple bottom support blocks 122 to move upward until the multiple bottom support blocks 122 fit against the bottom of the busbar groove, increasing the force-bearing area at the bottom of the busbar groove.

[0103] Step 6: After the position of the busbar groove is fixed, the adjacent busbar grooves can be connected at this time, and then the auxiliary unit 2 is removed.
