Description

Technical Field

[0001] This invention belongs to the field of photovoltaic equipment installation technology, specifically a bolt delivery device for the installation of offshore photovoltaic equipment. Background Technology

[0002] The installation of offshore photovoltaic (PV) equipment is a crucial link in the development of the new energy industry, and its background technology relies on a deep understanding of the marine environment and the application of innovative technologies. To overcome the complexity of the marine environment and ensure the stability and corrosion resistance of the equipment, operators need to use a large number of hexagonal bolts to tighten the connections between the various frames of the PV support system during installation. Because the offshore PV support platform is located at a considerable distance from the sea surface, sufficient bolts are needed to meet the needs of operators installing the PV equipment supports and avoid the time-consuming process of repeatedly climbing up and down the supports. However, the combined weight of these bolts can typically reach tens of kilograms, which increases the difficulty of movement for operators on the supports, reducing installation efficiency and increasing the risks involved. Therefore, to address these issues, a bolt delivery device for offshore PV equipment installation is proposed. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a bolt delivery device for the installation of offshore photovoltaic equipment, which solves the problem that carrying a large number of bolts to install photovoltaic brackets reduces installation efficiency and increases installation risks.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a bolt delivery device for the installation of offshore photovoltaic equipment, comprising a support and an air pump installed on one side thereof, the support comprising a connecting pipe installed inside therein and a constant pressure hole opened on the support, and further comprising: a feeding pipe fixedly installed on the top of the support for feeding bolts; a feeding tray movably installed inside the support for delivering individual bolts; a rotating assembly disposed inside the support and drivenly connected to the feeding tray; and a receiving assembly installed at one end of the connecting pipe for receiving bolts;

[0005] The feeding tray includes an annular array of arc-shaped openings on the feeding tray for storing a bolt. When the feeding tray rotates, there is always one arc-shaped opening with its two sides connected to the output end of the air pump and the connecting pipe, respectively.

[0006] The feeding pipe includes a feeding channel formed thereon, and the bottom end of the feeding channel is connected to the arc-shaped opening on the feeding tray that rotates to the top.

[0007] The receiving assembly includes a receiving box located on one side of the support. A flexible hose is fixedly connected between the receiving box and the connecting pipe. A directional channel opened on the receiving box is connected to the connecting pipe through the flexible hose. An elastic baffle is also elastically hinged to the top of the receiving box. A slot is opened at the bottom of the elastic baffle, and the top of the elastic baffle is above the directional channel. An elastic support block is elastically supported inside the receiving box. One end of the elastic support block extends into the directional channel and its end face is inclined.

[0008] When the bolt moves upward in the directional channel, it can squeeze the inclined end of the elastic support block and force the other end of the elastic support block into the slot.

[0009] Preferably, the top cross-section of the feeding channel is T-shaped, and the head of the T-shaped cross-section faces the receiving component.

[0010] Preferably, an elastic buckle is fixedly connected to one side of the receiving box, and a buffer airbag located directly above the directional channel is fixedly installed on the top of the elastic baffle, with a gap between the buffer airbag and the top of the directional channel that is smaller than the overall length of the bolt.

[0011] Preferably, the elastic support block has a notch at one end located in the directional channel. The width of the notch is smaller than the diameter of the bolt head and larger than the diameter of the bolt shank. The distance between the top of the notch and the bottom of the buffer airbag is greater than the height of the bolt head.

[0012] Preferably, the inner wall of the feeding tray is further provided with an elastic telescopic column, which includes a housing and an elastic convex shaft. The housing is fixed to the inner wall of the feeding tray, and the elastic convex shaft passes through the housing and extends into the channel at the center of the feeding tray.

[0013] Preferably, the rotating assembly includes a piston rod movably fitted inside the feeding disc and movable within the support; guide grooves arranged in a circular array on the piston rod; and a splined shaft elastically supported inside the piston rod and fixedly connected at one end to the support.

[0014] The connecting pipe is also connected to a bend. The gas pumped into the connecting pipe by the air pump enters the bend and can push the piston rod away from the bend, and compress the spring between the spline shaft and the piston rod.

[0015] Preferably, the portion of the piston rod facing the air pump and between it and the inner wall of the support is a cavity, and the support is also provided with a constant pressure hole, through which the cavity communicates with the outside.

[0016] Preferably, two adjacent guide grooves are connected, and the elastic convex shaft of the elastic telescopic column can slide within the guide groove;

[0017] The guide groove includes a horizontal groove, a first ramp, a ramp and a second ramp. The horizontal groove and the ramp are connected at the ends away from the spline shaft. The first ramp is disposed in the horizontal groove near the end of the ramp.

[0018] The elastic convex shaft of the elastic telescopic column is initially located in the transverse groove. When the piston column moves away from the bend, the elastic convex shaft of the elastic telescopic column moves unidirectionally and sequentially into the inclined groove along the transverse groove and the second slope.

[0019] Preferably, the end of the inclined groove near the spline shaft is connected to the end of the adjacent transverse groove near the spline shaft, and the second ramp is disposed in the inclined groove near the end of the adjacent transverse groove;

[0020] When the piston rod is reset, the elastic convex shaft of the elastic telescopic rod moves sequentially along the inclined groove and the second inclined slope and enters the adjacent transverse groove.

[0021] Preferably, the number of guide grooves is equal to the number of arc-shaped openings.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] The above solution, through the coordination of structures such as hoses, elastic baffles, air pumps, and arc-shaped openings, enables the device to reduce the number of bolts carried, thereby improving operator safety. By operating the air pump, gas pushes the bolt in the arc-shaped opening along the connecting pipe and hose into the directional channel, causing the bolt head to be squeezed and pass over the elastic support block until the bolt head hits the buffer airbag and stops moving. At the same time, the elastic support block will also be reset by its own elastic force and lift the bolt head. When the operator needs to use the bolt, he only needs to rotate the elastic baffle to remove the bolt from the directional channel, thus solving the problem of operators having to carry a large number of bolts, which increases the risk of work.

[0024] The above-described scheme utilizes the coordination of structures such as the elastic telescopic column, piston column, inclined groove, and splined shaft to ensure a continuous supply of bolts by rotating the feed pan. Gas pumped in by the air pump enters the bend, pushing the piston column towards the air pump and compressing the spring on the splined shaft. Simultaneously, the elastic convex shaft of the elastic telescopic column moves unidirectionally along the transverse groove and the second inclined groove, at which point the feed pan is stationary. When the air pressure in the bend returns to normal, the elastic convex shaft of the elastic telescopic column moves along the inclined groove and the second inclined groove, entering the adjacent transverse groove. At this point, the bottom arc-shaped opening on the feed pan is replaced by an adjacent arc-shaped opening containing a bolt, facilitating the delivery of the next bolt. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown, the present invention provides a bolt delivery device for the installation of offshore photovoltaic equipment, including a support 1 and an air pump 6 installed on one side thereon. The support 1 includes a connecting pipe 11 installed inside thereon and a constant pressure hole 12 opened on the support 1. It also includes: a feeding pipe 2, which is fixedly installed on the top of the support 1 for feeding bolts; a feeding tray 3, which is movably installed inside the support 1 for delivering single bolts; a rotating assembly 4, which is disposed inside the support 1 and drivenly connected to the feeding tray 3; and a receiving assembly 5, which is installed at one end of the connecting pipe 11 for receiving bolts.

[0036] The feeding tray 3 includes an arc-shaped opening 31 in a ring array on the feeding tray 3 for storing a bolt. When the feeding tray 3 rotates, there is always an arc-shaped opening 31 on both sides that is connected to the output end of the air pump 6 and the connecting pipe 11 respectively.

[0037] The feeding pipe 2 includes a feeding channel 21 opened thereon, and the bottom end of the feeding channel 21 is connected to the arc-shaped opening 31 on the feeding plate 3 that rotates to the top.

[0038] The receiving assembly 5 includes a receiving box 51 located on one side of the support 1. A flexible hose 52 is fixedly connected between the receiving box 51 and the connecting pipe 11. A directional channel 511 opened on the receiving box 51 is connected to the connecting pipe 11 through the flexible hose 52. An elastic baffle 54 is also elastically hinged to the top of the receiving box 51. A slot 541 is opened at the bottom of the elastic baffle 54, and the top of the elastic baffle 54 is above the directional channel 511. A buffer airbag 542 located directly above the directional channel 511 is also fixedly installed on the top of the elastic baffle 54. An elastic support block 53 is elastically supported inside the receiving box 51. One end of the elastic support block 53 extends into the directional channel 511 and its end face is inclined.

[0039] When the bolt moves upward in the directional channel 511, it can press the inclined end of the elastic support block 53 and force the other end of the elastic support block 53 into the slot 541.

[0040] Using the above scheme, by operating the air pump 6, the gas pushes the bolt in the arc-shaped port 31 into the directional channel 511 along the connecting pipe 11 and the hose 52, thereby causing the bolt head to be squeezed and pass over the elastic support block 53 until the bolt head hits the buffer airbag 542 and stops moving. At the same time, the elastic support block 53 will also be reset by its own elastic force and lift the bolt head. When the operator needs to use the bolt, he only needs to rotate the elastic baffle 54 to take the bolt out of the directional channel 511 for use.

[0041] like Figure 1-2 As shown, the top cross-section of the feeding channel 21 is "T" shaped, and the head of the "T" shaped cross-section faces the receiving component 5.

[0042] By adopting the above scheme, through the design of the "T"-shaped cross section at the top of the feeding channel 21, when the operator puts the bolt into the feeding channel 21, the head of the bolt can only face the receiving component 5, thereby ensuring that when the subsequent bolts are transported to the directional channel 511, the head of the bolt is always facing upward.

[0043] like Figure 1 , Figure 4 and Figure 6-7 As shown, an elastic buckle 512 is also fixed to one side of the receiver box 51, and a gap smaller than the overall length of the bolt is left between the buffer airbag 542 and the top of the directional channel 511.

[0044] The elastic support block 53 has a notch 531 at one end inside the directional channel 511. The width of the notch 531 is smaller than the diameter of the bolt head and larger than the diameter of the bolt shank. The distance between the top of the notch 531 and the bottom of the buffer airbag 542 is greater than the height of the bolt head.

[0045] By adopting the above solution, a gap smaller than the overall length of the bolt is left between the buffer airbag 542 and the top of the directional channel 511, thereby preventing the bolt from coming out of the directional channel 511 when it moves upward within the directional channel 511.

[0046] Since the width of the notch 531 is smaller than the diameter of the bolt head but larger than the diameter of the bolt shank, it ensures that the bolt head can compress the inclined part of the elastic support block 53 while moving upward, and also allows the bolt shank to move within the notch 531, thereby giving the elastic support block 53 a better lifting effect on the bolt head.

[0047] Such as 3-5 and Figure 8 As shown, the inner wall of the feeding tray 3 is also provided with an elastic telescopic column 32. The elastic telescopic column 32 includes two parts: a housing and an elastic convex shaft. The housing is fixed to the inner wall of the feeding tray 3, and the elastic convex shaft passes through the housing and extends into the channel at the center of the feeding tray 3. The rotating assembly 4 includes a piston column 41 that is movably sleeved inside the feeding tray 3 and can move within the support 1; guide grooves 42 arranged in a circular array and opened on the piston column 41; and a spline shaft 43 that is elastically supported inside the piston column 41 and fixedly connected to the support 1 at one end.

[0048] The connecting pipe 11 is also connected to a bend 111. The gas pumped into the connecting pipe 11 by the air pump 6 enters the bend 111 and can push the piston rod 41 away from the bend 111, and compress the spring between the spline shaft 43 and the piston rod 41.

[0049] Two adjacent guide grooves 42 are connected, and the elastic convex shaft of the elastic telescopic column 32 can slide in the guide groove 42; the guide groove 42 includes a transverse groove 421, a first ramp 422, a ramp 423 and a second ramp 424, the transverse groove 421 and the ramp 423 are connected at the ends away from the spline shaft 43, and the first ramp 422 is set in the transverse groove 421 near the end of the ramp 423;

[0050] Initially, the elastic convex shaft of the elastic telescopic column 32 is located in the transverse groove 421. When the piston column 41 moves away from the bend 111, the elastic convex shaft of the elastic telescopic column 32 moves unidirectionally and sequentially enters the inclined groove 423 along the transverse groove 421 and the second slope 424.

[0051] The portion of the piston rod 41 facing the air pump 6 and the inner wall of the support 1 is a cavity. A constant pressure hole 12 is also provided on the support 1, and the cavity is connected to the outside through the constant pressure hole 12.

[0052] Using the above scheme, when the piston rod 41 moves away from the bend 111, the elastic convex shaft of the elastic telescopic rod 32 enters the inclined groove 423 along the transverse groove 421 and the second inclined slope 424 in sequence. During this process, the sliding of the elastic telescopic rod 32 in the transverse groove 421 can play a circumferential limiting role on the feeding plate 3, avoiding the situation where the air pump 6 can cause the feeding plate 3 to rotate when pumping in gas, thereby ensuring the stability of the device during operation.

[0053] like Figure 3-5 and Figure 8 As shown, the inclined groove 423 is connected to the end of the adjacent transverse groove 421 near the spline shaft 43 at one end, and the second ramp 424 is provided in the inclined groove 423 near the end of the adjacent transverse groove 421.

[0054] When the piston rod 41 is reset, the elastic convex shaft of the elastic telescopic rod 32 moves sequentially along the inclined groove 423 and the second inclined slope 424 and enters the adjacent transverse groove 421.

[0055] The number of guide grooves 42 is equal to the number of arc-shaped openings 31;

[0056] Using the above scheme, when the piston rod 41 is reset, the elastic convex shaft on the feeding plate 3 can move along the inclined groove 423, thereby driving the feeding plate 3 to rotate as a whole through the elastic telescopic rod 32. At the same time, since the number of guide grooves 42 is equal to the number of arc-shaped openings 31, when the elastic convex shaft on the feeding plate 3 slides from the inclined groove 423 to the adjacent transverse groove 421, the arc-shaped opening 31 at the bottom of the feeding plate 3 will be replaced by the adjacent arc-shaped opening 31 that stores bolts inside, thereby ensuring that the device can continuously deliver bolts.

[0057] Working principle and usage process of this invention:

[0058] First, the air pump 6 is run, which pushes the bolt in the bottom arc-shaped opening 31 of the feeding plate 3 along the connecting pipe 11 and the hose 52 into the directional channel 511. The upward movement of the bolt head will squeeze the inclined surface of the elastic support block 53 and make the other end of the elastic support block 53 stuck in the slot 541. After the bolt head passes over the elastic support block 53 and hits the buffer airbag 542, it stops moving. At the same time, the elastic support block 53 will also be reset by its own elastic force and lift the bolt head. When the operator needs to use the bolt, he only needs to rotate the elastic baffle 54 to take the bolt out of the directional channel 511 for use.

[0059] When the air pump 6 pumps gas to move the bolt, the gas also enters the bend 111, pushing the piston 41 toward the air pump 6 and compressing the spring on the spline shaft 43. At the same time, the elastic convex shaft of the elastic telescopic column 32 moves unidirectionally and sequentially along the transverse groove 421 and the second ramp 424 into the inclined groove 423. At this time, the feed pan 3 is stationary. When the air pressure in the bend 111 returns to normal, the elastic convex shaft of the elastic telescopic column 32 moves sequentially along the inclined groove 423 and the second ramp 424 and enters the adjacent transverse groove 421. At this time, the bottom arc-shaped opening 31 on the feed pan 3 is replaced by the adjacent arc-shaped opening 31 that stores the bolt, so as to facilitate the delivery of the next bolt.
