Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power distribution construction protection, and in particular to a photovoltaic component power distribution protection device. Background Art

[0002] During the construction of photovoltaic module power distribution, in order to prevent the corrugated sheet (color steel tile) on the roof from collapsing, it is often necessary to install an operation and maintenance channel on the roof. In order to reduce weight, the existing operation and maintenance channels mostly adopt lightweight grid-type, which are laid to both ends of the roof through steel structures to prevent the distribution facilities from flattening the slope of the color steel tile during installation. The reserved operation and maintenance channel can facilitate the maintenance of the distribution facilities in the later stage and protect the building. In winter, ice will form on the top surface (walking surface) of the operation and maintenance channel, and the foot will feel serious slippery when stepping on it for maintenance, which poses a safety hazard.

[0004] As a further preference, the trigger plate is circular, the protrusion is arranged on the circumferential surface of the trigger plate, and two trigger plates installed on the control rod are arranged in the same grid.

[0005] As a further preferred embodiment, positioning holes are provided at both ends of the control rod, the positioning pins are inserted into the positioning holes, bushings are inlaid on the left and right sides of the operation and maintenance channel, and the two ends of the control rod are assembled and pass through the two bushings.

[0006] As a further preference, the outer end of the positioning pin is provided with a bent portion, one end of the suspension rod is connected to the undulating plate, and the other end of the suspension rod is vertically upward and provided with a hanging ring, and the hanging ring is hung on the bent portion.

[0007] As a further preference, the shape of the cleaning tube is consistent with the inner cavity shape of the grid in which it is located, the tube wall of the cleaning tube contacts each inner cavity wall of the grid in which it is located, chamfers are provided on both sides of the top of the grid, and when the protrusion rotates to leave the bottom end of the cleaning tube, the cleaning tube descends until its top end is flush with the top surface of the grid.

[0008] As a further preference, the bottom end of the cleaning tube is provided with an extension portion extending vertically downward and close to the bottom end of the grid inner cavity, the extension portions are in two locations and are symmetrically arranged on the front and rear sides of the control rod, and the outer wall surfaces of the two extension portions are in sliding contact with the inner wall surface of the grid.

[0009] As a further preferred embodiment, vertical sliding cavities are provided at the front and rear ends of the operation and maintenance channel, and the two counterweight seats can be slid up and down and fit in the sliding cavities respectively. A number of partitions are provided in each of the counterweight cavities, and the counterweight cavity is divided into a number of unit cavities by these partitions. A corresponding leakage hole is provided in each of the unit cavities, and a vertical downward leakage pipe is installed on each of the leakage holes. The leakage pipe is a conical tube that is thick at the top and thin at the bottom, and the tube cavity of the leakage pipe is also a conical cavity that is thick at the top and thin at the bottom. A layer of heating wire is sleeved on each of the leakage pipes. The heating wire is spiral and is wound around the leakage pipe from the bottom end of the leakage pipe upward, and the bottom ends of all the heating wires at the same end are connected to an electric wire together, and the electric wires at both ends are connected in series and connected to the photovoltaic circuit together.

[0010] As a further preference, the operation and maintenance channel is provided with a plurality of through grooves from one end to the other end in the length direction, the plurality of through grooves are equidistantly distributed along the width direction of the operation and maintenance channel, and each of the through grooves directly leads to the bottom of a row of the grids.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In rainy and snowy weather, the counterweight seat will increase in weight, and the rising and falling plates will descend along the guide rods and deflect downward with the control rods. The control rods will cause the trigger plates in each grid to rotate clockwise, causing the protrusions on the trigger plates to press against the cleaning tubes above them and rise along the grids where they are located, so that the top ends of the cleaning tubes protrude from the top surface of the grids where they are located, which is equivalent to the top ends of the cleaning tubes rising a distance relative to the top surface of the grids where they are located, causing the ice layer condensed on the top surface of the operation and maintenance channel to fall downwards.

[0013] When the temperature drops suddenly and the rain freezes on the top surface of the grid again, as the temperature warms up, the ice or snow in the counterweight cavity will melt, the counterweight seat will gradually become lighter, and the control lever will rotate counterclockwise with the trigger plate in each grid. The force of these protrusions on the bottom end of the cleaning pipe will decrease, and the cleaning pipe will descend along the grid where it is located, so that the top of the cleaning pipe will protrude from the top surface of the grid where it is located, and the top of the cleaning pipe will retreat into the grid. It can be seen that when the top of the cleaning pipe retreats into the grid, the oblique ice layer condensed on the top surface of the grid and the top of the cleaning pipe is pulled off, and the broken ice layer falls into the grid, falls from the grid to the color steel tile, and finally discharged outward from the through slot. The ice layer condensed on the top surface of the operation and maintenance channel is automatically cleaned, which can reduce slipping when walking on the operation and maintenance channel to maintain the power distribution facilities, and improve safety.

[0014] From the above, it can be seen that when the top surface of the operation and maintenance channel is initially frozen, a series of transmissions are used to automatically raise the cleaning pipe so that the ice layer is cleaned once. After freezing, as the counterweight seat becomes lighter, the cleaning pipe is automatically lowered through a series of transmissions, so that the ice layer is processed a second time. These two cleaning processes shorten the cleaning interval time. Whether the counterweight seat is raised or lowered is directly related to whether the accumulated snow or water is frozen in the counterweight cavity, that is, the lifting and lowering action of the cleaning pipe, and the power for cleaning the ice layer by using the lifting and lowering action comes from natural conditions. For the new energy field, this implementation method can reduce energy loss. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, if Figure 1-Figure 8 As shown: This embodiment provides a photovoltaic module power distribution protection device, including an operation and maintenance channel 1, the operation and maintenance channel 1 is a grid formed by splicing a plurality of channel plates 2, each grid 3 is provided with a set of cleaning components 4, and a plurality of control rods 5 are passed through along the width direction of the operation and maintenance channel 1, and each control rod 5 penetrates into each group of grids 3;

[0026] A undulating plate 6 is provided on each of the left and right sides of the operation and maintenance channel 1. Two guide rods 7 distributed front and back are welded on each of the two sides of the operation and maintenance channel 1. The front and rear ends of the undulating plate 6 penetrate the front and rear guide rods 7.

[0027] The cleaning assembly 4 includes a cleaning tube 8 inserted in each grid 3, and includes a plurality of trigger plates 9 mounted on the control rod 5, each trigger plate 9 is located in one grid 3, each trigger plate 9 is provided with a protrusion 10, each protrusion 10 is located at the bottom side of a cleaning tube 8, and the bottom end of the cleaning tube 8 contacts the trigger plate 9, and when the trigger plate 9 contacts the bottom end of the cleaning tube 8 through the protrusion 10, the cleaning tube 8 can be lifted upward from the grid 3;

[0028] The cleaning assembly 4 also includes positioning pins 11 installed at the left and right ends of each control rod 5, the positioning pins 11 are located outside the operation and maintenance channel 1, and the left and right undulating plates 6 are respectively located at the bottom sides of the left and right positioning pins 11. The cleaning assembly 4 also includes a suspension rod 12 connected between the positioning pins 11 and the undulating plates 6, and also includes a spring 13 sleeved on the guide rod 7, the top end of the spring 13 is against the bottom surface of the undulating plates 6, and the bottom end of the spring 13 is against the bottom end of the guide rod 7;

[0029] The cleaning component 4 also includes a counterweight seat 14 installed at the front and rear ends of the operation and maintenance channel 1, and the left and right ends of the counterweight seat 14 are respectively close to the left and right undulating plates 6. The cleaning component 4 also includes a connecting plate 15 connected to the left and right ends of the counterweight seat 14, and the other end of the connecting plate 15 is connected to the undulating plate 6. A counterweight cavity 16 is opened in the counterweight seat 14, and a drainage hole 17 connected to the counterweight cavity 16 up and down is opened at the bottom of the counterweight seat 14.

[0030] The bottom surface of the operation and maintenance channel 1 is fixed on the color steel tile by steel structures such as pull codes, so that a larger space is formed between the bottom surface of the operation and maintenance channel 1 and the color steel tile. When ice forms on the top surface (walking surface) of the operation and maintenance channel 1 in winter, the ice layer is mostly gathered on the top periphery of each grid 3, and the snow or rainwater falling in the grid 3 seeps into the bottom space and falls on the color steel tile. The ice layer gathered on the top periphery of each grid 3 (the ice layer in this area is collectively referred to as the ice layer below) will affect the stepping on the sole of the foot, and may even cause slipping during stepping. The present invention can make the ice layer fall off downward without human intervention. The principle is as follows: in rainy and snowy weather, both rainwater and snow will inevitably fall into the counterweight cavity 16, which will cause the two counterweight seats 14 to increase in weight. When the weight of the two counterweight seats 14 is greater than the supporting force of the spring 13 on the undulating plate 6, the spring 13 will compress The undulating plate 6 will be shortened. At this time, the undulating plate 6 will descend along the guide rod 7, and at the same time, all the positioning pins 11 will be deflected downward, and these positioning pins 11 will deflect downward with the control rods 5 where they are located. These control rods 5 will rotate the trigger plate 9 in each grid 3 clockwise, and these trigger plates 9 will rotate clockwise with the protrusions 10, so that these protrusions 10 will press against the cleaning tubes 8 above them and rise along the grid 3 where they are located, so that the top of the cleaning tube 8 will protrude from the top surface of the grid 3 (that is, the walking surface of the operation and maintenance channel 1). The rising amplitude of the cleaning tube 8 will continue until the spring 13 reaches the compression limit. When the top of the cleaning tube 8 rises to protrude from the top surface of the grid 3 where it is located, it is equivalent to the top of the cleaning tube 8 rising a distance relative to the top surface of the grid 3 where it is located, which is equivalent to causing the ice layer condensed on the top surface of the operation and maintenance channel 1 to fall downward, and the fallen ice layer will fall into the grid 3.When the temperature drops suddenly and the rain freezes on the top surface of the grid 3 again, the ice layer will not only condense on the top surface of the grid 3, but also condense on the top of the cleaning pipe 8. Since the top of the cleaning pipe 8 is higher than the top surface of the grid 3 at this time, the ice layer will condense in an inclined manner between the top of the cleaning pipe 8 and the top of the grid 3. As the temperature rises, the ice or snow in the counterweight cavity 16 will melt, and the melted water will be discharged from the drain hole 17. At this time, the counterweight seat 14 gradually becomes lighter. When its weight is lower than the pressure on the spring 13 through the undulating plate 6, the spring 13 will release its length and push the undulating plate 6 to rise. The undulating plate 6 drives all the suspension rods 12 to rise, and all the suspension rods 12 push all the positioning pins 11 Deflect counterclockwise, the positioning pin 11 drives all the control rods 5 to deflect counterclockwise, and these control rods 5 drive the trigger plates 9 in each grid 3 to rotate counterclockwise, and these trigger plates 9 drive the protrusions 10 to rotate counterclockwise, and the force of these protrusions 10 on the bottom end of the cleaning pipe 8 is reduced, and the cleaning pipe 8 will descend along the grid 3, so that the top of the cleaning pipe 8 protrudes from the top surface of the grid 3 (that is, the walking surface of the operation and maintenance channel 1), and the top of the cleaning pipe 8 retreats into the grid 3. It can be seen that when the top of the cleaning pipe 8 retreats into the grid 3, the oblique ice layer condensed on the top surface of the grid 3 and the top of the cleaning pipe 8 is broken, and the broken ice layer falls into the grid 3, falls from the grid 3 to the color steel tile, and finally is discharged outward from the through groove 28. In short, the ice layer condensed on the top surface (walking surface) of the operation and maintenance channel 1 is automatically cleaned, and when walking on the operation and maintenance channel 1 to perform maintenance operations on the power distribution facilities, it can reduce slipping and improve safety.

[0031] From the above, it can be seen that when the top surface of the operation and maintenance channel 1 is initially frozen during ice formation, the counterweight seat 14 loses weight and descends, and through a series of transmissions, the cleaning pipe 8 automatically rises, so that the ice layer is cleaned once. After freezing, as the counterweight seat 14 becomes lighter and the cleaning pipe 8 automatically descends through a series of transmissions, the ice layer is processed a second time. These two cleaning processes shorten the cleaning interval time. Whether the counterweight seat 14 is raised and lowered is directly related to whether the accumulated snow or water in the counterweight cavity 16 is frozen, that is, the lifting and lowering action of the cleaning pipe 8, and the power for cleaning the ice layer by the lifting and lowering action comes from natural conditions. For the new energy field, this implementation method can reduce power loss.

[0032] like Figure 1 , Figure 2 as well as Figure 5 As shown, the trigger plate 9 is circular, and the protrusion 10 is arranged on the circumferential surface of the trigger plate 9. Two trigger plates 9 installed on the control rod 5 are arranged in the same grid 3. When the two trigger plates 9 in the same grid 3 rotate clockwise, the two protrusions 10 push the two sides of the bottom end of the cleaning tube 8, so that the rising action of the cleaning tube 8 is more stable, avoiding the occurrence of dead points when the cleaning tube 8 rises along the grid 3.

[0033] like Figure 2 As shown, positioning holes 18 are provided at both ends of the control rod 5, and the positioning pins 11 are inserted into the positioning holes 18. Bushings 19 are inlaid on the left and right sides of the operation and maintenance channel 1. The two ends of the control rod 5 are assembled and pass through the two bushings 19. The bushings 19 can also be bearings to assist the rotation of the control rod 5. The positioning holes 18 are installed with the positioning pins 11, which not only set limit stops at both ends of the control rod 5, but also use the deflection of the positioning pins 11 to drive the control rod 5 to complete synchronous deflection movement.

[0034] like Figure 2 As shown, the outer end of the positioning pin 11 is provided with a bent portion 20, one end of the suspension rod 12 is connected to the undulating plate 6, and the other end of the suspension rod 12 is vertically upward and provided with a hanging ring 21, which is hung on the bent portion 20. The hanging ring 21 and the suspension rod 12 are movably connected. When the suspension rod 12 is raised and lowered and drives the positioning pin 11 to deflect through the hanging ring 21, a dead point is avoided to affect the normal deflection action of the control rod 5.

[0035] like Figure 2 , Figure 3 As shown, in another embodiment, the shape of the cleaning tube 8 is consistent with the inner cavity shape of the grid 3 where it is located, the tube wall of the cleaning tube 8 contacts each inner cavity wall of the grid 3 where it is located, and chamfers 22 are provided on both sides of the top of the grid 3, that is, the edge of the grid 3 is a chamfered structure from the top to the bottom, and when the protrusion 10 rotates to leave the bottom of the cleaning tube 8, the cleaning tube 8 is lowered until its top is flush with the top surface of the grid 3. When the ice layer between the top surface of the grid 3 and the top of the cleaning tube 8 is pulled off and falls off by the lifting action of the cleaning tube 8, the fallen ice layer falls into the grid 3 from the chamfer 22, avoiding the ice layer still being retained on the top surface of the grid 3 or the top surface of the cleaning tube 8.

[0036] like Figure 8 As shown, the bottom end of the cleaning tube 8 is provided with an extension part 29 which is vertically downward and close to the bottom end of the inner cavity of the grid 3. There are two extension parts 29, which are symmetrically located at the front and rear sides of the control rod 5. The outer wall surfaces of the two extension parts 29 are in sliding contact with the inner wall surface of the grid 3. The extension part 29 extends the installation depth of the cleaning tube 8 in the grid 3, and also increases the effective contact area between the cleaning tube 8 and the inner wall of the grid 3. Although the cleaning tube 8 is lifted upward by the protrusion 10 due to the rotation of the trigger plate 9, it is still restricted in the grid 3 by the large-area extension part 29 to prevent the cleaning tube 8 from completely falling off from the grid 3.

[0037] like Figure 4As shown, in another embodiment, a vertical sliding cavity 23 is provided at the front and rear ends of the operation and maintenance channel 1, and the two counterweight seats 14 can slide up and down and fit in the sliding cavity 23 respectively. A plurality of partitions 24 are provided in each counterweight cavity 16, and the counterweight cavity 16 is divided into a plurality of unit cavities 25 by these partitions 24. A corresponding drainage hole 17 opened at the bottom of the counterweight seat 14 is provided in each unit cavity 25, and a vertical downward drainage pipe 26 is installed on each drainage hole 17. The drainage pipe 26 is a conical tube with a thick top and a thin bottom, and the tube cavity of the drainage pipe 26 is also a conical cavity with a thick top and a thin bottom. When snow accumulates in the counterweight cavity 16, it will be distributed in each unit cavity 25. Since the accumulated snow is distributed in these unit cavities 25 by scraping and cutting, when the temperature rises, the melting rate of the accumulated snow in the counterweight cavity 16 can be increased. Even if the melting rate is slow, people can control the power supply of the heating wire 27 through the operating room on the ground to heat these discharge pipes 26, which greatly improves the lightening speed of the counterweight seat 14, speeds up the automatic descent of the cleaning pipe 8, and accelerates the efficiency of breaking the ice layer. This provides convenience for people who urgently step into the operation and maintenance channel 1 to maintain the power distribution facilities.

[0038] The spring 13 mentioned in the present invention can be replaced by an existing automatic reset mechanism or element such as a gas spring. That is, the spring 13 in the present invention is not limited to a spring as an automatic reset mechanism.

[0039] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0040] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
