Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and particularly relates to a sleeve for the construction of a photovoltaic bracket foundation on a pit surface. Background Technique

[0002] In order to efficiently utilize limited land resources, photovoltaic power generation panels are selected to be installed in some pit areas. When installing the photovoltaic power generation panels, the feet of the brackets are generally installed by pre-burying a plurality of sleeves.

[0003] In the prior art, a photovoltaic bracket pre-burial disclosed in the patent with the publication number of CN220173134U makes the pre-buried pile laid more stably through a bracket, a first fixing plate, fixing holes, a second fixing plate, locking bolts, threaded rods, threaded sleeves, pre-buried sleeves, limiting ports, movable sleeves, limiting rings, and compression springs. However, the depth of the pre-buried sleeve is fixed. When the heights of the four pre-buried cylinders are different, if the feet are directly placed in, it is easy to tilt, posing a safety hazard. There are also cases where the feet of the bracket are cut and are in a horizontal state during installation. However, measuring and cutting back and forth increases the working intensity of the staff and is not convenient to use. In view of the deficiencies of the prior art, the utility model discloses a sleeve for the construction of a photovoltaic bracket foundation on a pit surface to solve the above problems. Content of the Utility Model

[0004] The purpose of this application is to provide a sleeve for the construction of a photovoltaic bracket foundation on a pit surface to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, this application provides the following technical solution: A sleeve for the construction of a photovoltaic bracket foundation on a pit surface includes a pre-buried sleeve and a threaded sleeve. A lifting groove is opened on the inner wall of the side part of the pre-buried sleeve. A threaded rod is rotatably installed on the opposite inner walls of the lifting groove. A knob is installed at the top of the threaded rod. A threaded block is threadedly sleeved on the threaded rod. A lifting plate is installed at the top of the threaded block. The threaded sleeve is installed at the top of the lifting plate. Two lifting blocks are arranged in the pre-buried sleeve. Two damping telescopic rods are installed at the top of each of the two lifting blocks. Support plates are installed at the ends of the four damping telescopic rods. Buffer springs are installed at the bottom of the four support plates. The other ends of the four buffer springs are respectively installed at the top of the two lifting blocks. A driven mechanism for moving the two lifting blocks is arranged on the pre-buried sleeve, and the driven mechanism is cooperatively installed with the threaded rod.

[0006] Preferably, the driven mechanism includes two grooves formed in the inner wall of the side portion of the embedded sleeve. Anti-threaded lead screws are rotatably installed on the inner walls of the side portions of the two grooves and the inner wall of the side portion of the embedded sleeve respectively. Two movable blocks are threadedly sleeved on each of the two anti-threaded lead screws. Oblique plates are rotatably installed on the tops of the four movable blocks. The other ends of the two oblique plates on the same side are rotatably installed at the bottom of one of the lifting blocks. The two anti-threaded lead screws are cooperatively installed with the threaded rod through a transmission unit.

[0007] Preferably, a guide groove is formed in the inner wall of the side portion of the embedded sleeve. Guide rods are installed on the opposite inner walls of the guide groove. A guide hole is formed in the top of the threaded block. The guide rod penetrates through the guide hole. Two limit rods are installed on the opposite inner walls of the embedded sleeve. Limit holes are formed in the side portions of the four movable blocks. The two limit rods sequentially penetrate through the two limit holes on the same side respectively.

[0008] Preferably, the transmission unit includes a first bevel gear sleeved on the threaded rod. Second bevel gears are sleeved on each of the two anti-threaded lead screws. Transmission holes communicating with the lifting grooves are formed in the inner walls of the side portions of the two grooves. Transmission rods are rotatably installed on the two transmission holes. Third bevel gears are installed at both ends of the two transmission rods. The two third bevel gears close to each other are meshed with the first bevel gear. The two third bevel gears away from each other are respectively meshed with the two second bevel gears.

[0009] Preferably, the diameter of the first bevel gear is smaller than the diameter of the second bevel gear.

[0010] Preferably, a threaded hole is formed in the side portion of the embedded sleeve. A fixing bolt is threadedly installed in the threaded hole. The end of the fixing bolt abuts against the threaded rod.

[0011] Preferably, a limit block is installed on the inner wall of the bottom of the embedded sleeve.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

[0013] 1. In the present utility model, during use, first rotate the knob. The rotation of the knob causes the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to move up and down through the threaded block and the lifting plate, thereby adjusting the height of the threaded sleeve. As a result, the bracket can be made horizontal without cutting the support feet, which is convenient for use. At the same time, the rotation of the threaded rod drives the lifting block to move up and down through the first bevel gear, the second bevel gear, the transmission rod, the third bevel gear, the left - right - hand threaded rod, the movable block and the inclined plate. The up - and - down movement of the lifting block drives the support plate to move up and down through the damping telescopic rod, so that the support plate always supports the lifting plate, providing auxiliary support for the lifting plate and making the lifting plate more stable. Also, when the threaded block is damaged and the lifting plate drops, the damping telescopic rod and the buffer spring can buffer the lifting plate, reducing the vibration generated during the drop, which is convenient for use.

[0014] 2. In the present utility model, the provision of the fixing bolt facilitates the fixing of the threaded rod, preventing the situation where the threaded rod rotates by itself and causes the threaded block to move up and down. The provision of the limiting block plays a certain limiting role, preventing the threaded block from contacting the first bevel gear and affecting the first bevel gear.

Detailed implementation manners

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Refer to Figures 1-4 A sleeve for the construction of a photovoltaic support foundation on a pit surface, which includes an embedded sleeve 1 and a threaded sleeve 7. A lifting groove is formed in the inner wall of the side of the embedded sleeve 1. A threaded rod 2 is rotatably installed on the opposite inner walls of the lifting groove. A knob 3 is installed at the top of the threaded rod 2. A threaded block 4 is threadedly sleeved on the threaded rod 2. A lifting plate 6 is installed at the top of the threaded block 4. The threaded sleeve 7 is installed on the top of the lifting plate 6. Two lifting blocks 16 are arranged in the embedded sleeve 1. Two damping telescopic rods 17 are installed at the top of each of the two lifting blocks 16. The ends of the four damping telescopic rods 17 are all installed with support plates 18. Buffer springs 19 are installed at the bottom of the four support plates 18. The other ends of the four buffer springs 19 are respectively installed on the top of the two lifting blocks 16. A driven mechanism for moving the two lifting blocks 16 is arranged on the embedded sleeve 1, and the driven mechanism is cooperatively installed with the threaded rod 2.

[0023] With the above structure, when in use, first rotate the knob 3. The rotation of the knob 3 will cause the threaded rod 2 to rotate. The rotation of the threaded rod 2 will cause the threaded block 4 to move up and down. The up and down movement of the threaded block 4 will cause the lifting plate 6 to move up and down. The up and down movement of the lifting plate 6 will cause the threaded sleeve 7 to move up and down, thereby adjusting the height of the threaded sleeve 7, so that the bracket can be in a horizontal state without cutting the support feet, which is convenient for use. At the same time, the rotation of the threaded rod 2 will cause the lifting block 16 to move up and down through the driven mechanism. The up and down movement of the lifting block 16 will cause the support plate 18 to move up and down through the damping telescopic rod 17, so that the support plate 18 always supports the lifting plate 6, thereby assisting in supporting the lifting plate 6 and making the lifting plate 6 more stable. At the same time, when the threaded block 4 is damaged and the lifting plate 6 drops, the damping telescopic rod 77 and the buffer spring 198 can buffer the lifting plate 6 and reduce the vibration generated during the drop, which is convenient for use.

[0024] As Figure 2As shown, the driven mechanism includes two grooves formed in the inner wall of the side of the embedded sleeve 1. The inner walls of the sides of the two grooves are respectively rotatably installed with left - hand and right - hand lead screws 9 on the inner wall of the side of the embedded sleeve 1. Two movable blocks 13 are threadedly sleeved on the two left - hand and right - hand lead screws 9. The tops of the four movable blocks 13 are respectively rotatably installed with inclined plates 15. The other ends of the two inclined plates 15 on the same side are rotatably installed at the bottom of one of the lifting blocks 16. The two left - hand and right - hand lead screws 9 are cooperatively installed with the threaded rod 2 through a transmission unit. The advantage of this setting is that through the setting of the left - hand and right - hand lead screws 9, movable blocks 13 and inclined plates 15, it is convenient to lift the lifting block 16.

[0025] Specifically, when the left - hand and right - hand lead screw 9 rotates, the two movable blocks 13 will approach or move away from each other. When the two movable blocks 13 approach or move away from each other, they will give an upward or downward force to the lifting block 16 through the inclined plate 15, thereby causing the lifting block 16 to rise and fall, so that the support plate 18 always contacts the bottom of the lifting plate 6 to assist in supporting it.

[0026] As Figure 2 shown, a guiding groove is formed in the inner wall of the side of the embedded sleeve 1. Guide rods 5 are installed on the opposite inner walls of the guiding groove. A guiding hole is formed in the top of the threaded block 4. The guide rod 5 penetrates through the guiding hole. Two limiting rods 14 are installed on the opposite inner walls of the embedded sleeve 1. Limiting holes are formed in the sides of the four movable blocks 13. The two limiting rods 14 respectively penetrate through the two limiting holes on the same side in sequence. The advantage of this setting is that through the setting of the guide rod 5 and the limiting rod 14, a certain guiding effect is achieved, enabling the threaded block 4 and the movable blocks 13 to move along the horizontal direction.

[0027] As Figure 3 shown, the transmission unit includes a first bevel gear 8 sleeved on the threaded rod 2. Second bevel gears 10 are sleeved on the two left - hand and right - hand lead screws 9. Transmission holes communicating with the lifting grooves are formed in the inner walls of the sides of the two grooves. Transmission rods 11 are rotatably installed on the two transmission holes. Third bevel gears 12 are installed at both ends of the two transmission rods 11. The two mutually approaching third bevel gears 12 are both meshed with the first bevel gear 8. The two mutually separating third bevel gears 12 are respectively meshed with the two second bevel gears 10. The advantage of this setting is that through the setting of the first bevel gear 8, second bevel gears 10, transmission rods 11 and third bevel gears 12, the threaded rod 2 and the two left - hand and right - hand lead screws 9 rotate simultaneously.

[0028] Specifically, when the threaded rod 2 rotates, the first bevel gear 8 will rotate. When the first bevel gear 8 rotates, two of the third bevel gears 12 will rotate. When two of the third bevel gears 12 rotate, the two transmission rods 11 will rotate respectively. When the two transmission rods 11 rotate, the other two third bevel gears 12 will rotate. When the other two third bevel gears 12 rotate, the two second bevel gears 10 will rotate. When the two second bevel gears 10 rotate, the two left - right hand threaded rods 9 will rotate, so that the threaded rod 2 and the two left - right hand threaded rods 9 rotate simultaneously.

[0029] As Figure 3 shown, the diameter of the first bevel gear 8 is smaller than the diameter of the second bevel gear 10. The advantage of this setting is that the rotation speeds of the threaded rod 2 and the left - right hand threaded rod 9 are different, avoiding the lifting block 16 from lifting too fast.

[0030] As Figure 1 shown, a threaded hole is provided on the side of the embedded sleeve 1. A fixing bolt 20 is threadedly installed in the threaded hole, and the end of the fixing bolt 20 abuts against the threaded rod 2. The advantage of this setting is that through the setting of the fixing bolt 20, it is convenient to fix the threaded rod 2 and avoid the situation where the threaded block 4 is lifted or lowered due to the self - rotation of the threaded rod 2.

[0031] As Figure 2 shown, a limiting block is installed on the bottom inner wall of the embedded sleeve 1. The advantage of this setting is that through the setting of the limiting block, a certain limiting effect is achieved, avoiding the threaded block 4 from contacting the first bevel gear 8 and affecting the first bevel gear 8.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
