Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic engineering technology, specifically, it relates to an auxiliary device for photovoltaic pile foundation pouring. Background Technology

[0002] Photovoltaic pile foundation pouring refers to the process of constructing the foundation in the form of piles to support photovoltaic (PV) brackets and panels in PV power generation projects. Common auxiliary equipment used in PV pile foundation pouring includes pile drivers, mixers, vibrators, formwork, measuring instruments, and cover plates. When laying PV brackets, a foundation pit needs to be dug in the ground beforehand. Then, a pile driver is used to drive the piles to the predetermined depth. Subsequently, concrete is poured into the piles, and a vibrator is used to compact it. After the cement hardens, the pile foundation is formed. A stable and reliable pile foundation can then be used to fix the PV brackets, completing the PV installation.

[0003] The foundation pit is a crucial component of pile foundations. To ensure the stability of the pile foundation, it is necessary to protect the pit before pouring cement, preventing the entry of debris, soil, stones, or other objects that could impede the structural performance of the pile foundation. This protection is especially important during rainy weather, as rainwater seepage can cause soil loosening or affect the quality of the concrete. The simplest method is to cover the pit with slabs or waterproof fabric after excavation to stabilize the soil and prevent erosion. Simultaneously, it is essential to prevent rainwater from diluting the concrete, ensuring that the strength and stability of the poured concrete remain unaffected.

[0004] However, while protective measures such as covers and waterproof tarpaulins can prevent rainwater from directly entering the foundation pit to some extent, they also have some drawbacks. First, in the event of heavy rain or prolonged downpours, these measures may not completely prevent water penetration, leading to water accumulation in the foundation pit and affecting the stability of the pile foundation. Second, waterproof tarpaulins and covers have poor wind resistance and are easily damaged by strong winds, failing to effectively protect the foundation pit. Furthermore, these measures require frequent inspection and maintenance, increasing the difficulty and cost of construction management. In short, although these measures can provide temporary protection, they may be insufficient to ensure construction quality and safety under extreme weather conditions. Utility Model Content

[0005] To address the technical problem that existing foundation pit protection methods, such as cover plates and waterproof fabrics, cannot effectively protect foundation pits during rainy or windy weather, this utility model provides an auxiliary device for photovoltaic pile foundation pouring.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An auxiliary device for photovoltaic pile foundation pouring includes a protective sleeve with a corrugated structure; an annular block is connected to the bottom of the protective sleeve; a water-proof annular block is fixed to the bottom of the annular block; the cross-section of the water-proof annular block is conical; and a waterproof plate is provided at the upper end of the protective sleeve.

[0008] Furthermore, an annular groove is provided on the annular block, and the bottom end of the protective sleeve is connected to the bottom of the annular groove; the position of the annular block corresponding to the inner side of the annular groove is a sunken structure.

[0009] Furthermore, an annular protrusion is fixed to the bottom of the outer side of the annular block; multiple circular holes in a circumferential array are opened on the protrusion; and insert rods are detachably installed in the circular holes.

[0010] Furthermore, multiple circumferentially arranged cuts are made at the bottom of the outer surface of the annular block.

[0011] Furthermore, the lower end of the insertion rod has a tapered structure.

[0012] Furthermore, the inflection points on the protective cover are all fixed with ring-shaped reinforcing ribs.

[0013] Furthermore, the upper side of the protective sleeve is fixed with three circumferentially arranged limiting blocks, which are L-shaped and have a chamfer at one end. The protective sleeve has a limiting groove corresponding to the position of the limiting block, which is semi-circular. The protective sleeve is also fixed with a limiting block corresponding to the side of the limiting groove.

[0014] Furthermore, a fixing block is fixedly connected to the inner side of the waterproof membrane at the position corresponding to the limiting groove, and the fixing block and the limiting groove fit together.

[0015] The beneficial effects of this utility model are:

[0016] 1) This utility model places the annular block at the bottom of the protective sleeve at the top of the foundation pit, and then applies force to the annular block from above, so that the water-proof ring block is embedded in the soil layer around the top of the foundation pit to form a sealed structure to prevent rainwater from seeping into the foundation pit. After that, the waterproof board is placed on top of the protective sleeve, and the protective sleeve is secured to the top of the protective sleeve by the cooperation of the limiting block and the fixing block. This can prevent stones, soil and garbage from entering the foundation pit and affecting the structural performance of the subsequent pile foundation.

[0017] 2) This utility model uses a rod inserted deep into the soil through a round hole and a convex edge to fix the ring block, preventing it from shifting due to wind or external contact, thus preventing the protective sleeve from losing its protective function.

[0018] 3) This utility model allows for the construction of pile foundations by pouring cement into the foundation pit. The retractable protective sleeve can be pulled up and opened to form a cavity that can accommodate the cement. After the cement solidifies, it automatically forms a pile foundation structure that protrudes above the foundation pit. There is no need to use additional surrounding panels to construct a cement template structure, which is convenient and quick. The setting of reinforcing bars can improve the stability of the protective sleeve before the cement solidifies and further improve the firmness of the pile foundation after the cement solidifies.

[0019] 4) Since the shape of the cement can be fixed on the top of the protective sleeve, this utility model can play a role in sheltering from wind and rain before the cement solidifies and forms, thus avoiding damage to the pile foundation caused by rainwater erosion and wind erosion, and resulting in economic losses.

[0020] 5) Because the protective sleeve is retractable and the annular block is positioned inside the annular groove in a sunken structure, the protective sleeve and waterproof board can be stored inside the annular groove before use, making them easy to store and carry, thus improving the convenience of photovoltaic operations.

[0031] Please see Figures 1-3 and Figure 5 As shown, an auxiliary device for photovoltaic pile foundation pouring includes a protective sleeve 1, which has a corrugated structure; annular reinforcing ribs 3 are fixedly connected to the inflection points of the protective sleeve 1; annular block 4 is connected to the bottom of the protective sleeve 1, and annular groove 7 is opened on the annular block 4 for receiving the protective sleeve 1, and the bottom of the protective sleeve 1 is connected to the bottom of the annular groove 7; the annular block 4 has a sunken structure corresponding to the position inside the annular groove 7.

[0032] A water-proof ring block 12 is fixed to the bottom of the annular block 4. The cross-section of the water-proof ring block 12 is conical. The water-proof ring block 12 is used to insert into the soil to prevent rainwater from entering the foundation pit and improve the sealing performance. Multiple circumferential array cuts 6 are opened at the bottom position of the outer surface of the annular block 4. The cuts 6 are used to drain the rainwater in the annular groove 7.

[0033] An annular protruding edge 5 is fixed to the bottom of the outer side of the annular block 4; a plurality of circular holes 51 in a circumferential array are opened on the protruding edge 5; a detachable insertion rod 52 is installed in the circular hole 51, the lower end of the insertion rod 52 is tapered, and the insertion rod 52 is used to fix the protruding edge 5 together with the annular block 4 to the periphery of the foundation pit in conjunction with the circular hole 51.

[0034] Please see Figure 4 As shown, a waterproof plate 2 is provided at the upper end of the protective cover 1. The waterproof plate 2 has a round cover-shaped structure. Anti-slip texture is provided on the side of the waterproof plate 2. The anti-slip texture is used to assist the staff in rotating to open or close the waterproof plate 2.

[0035] Please see Figure 6As shown, three limiting blocks 8 in a circumferential array are fixedly attached to the upper side of the protective sleeve 1. The limiting blocks 8 have an L-shaped structure and a chamfer at one end of the horizontal direction. The protective sleeve 1 has a limiting groove 9 corresponding to the position of the limiting blocks 8. The limiting groove 9 has a semi-circular structure. The protective sleeve 1 also has a limiting block 10 fixedly attached to the side of the limiting groove 9. The inner side of the waterproof plate 2 has a fixing block 11 fixedly attached to the position of the limiting groove 9, and the fixing block 11 fits into the limiting groove 9.

[0036] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0037] Before pouring cement into the foundation pit to form the foundation piles, if it is not necessary to pour cement immediately or if it is not possible to pour cement due to external weather, power or other factors, the annular block 4 can be placed at the top of the foundation pit. Then, force is applied to the annular block 4 from above, so that the waterproof ring block 12 is embedded in the soil layer around the top of the foundation pit, forming a sealed structure to prevent rainwater from seeping into the foundation pit. Then, the insert rod 52 is inserted deep into the soil layer through the round hole 51, and the convex edge 5 is used to fix the annular block 4 to prevent it from shifting due to wind force and external contact, which would cause the protective sleeve 1 to lose its protective function. After that, the waterproof board 2 is placed on top of the protective sleeve 1. The cooperation of the limiting block 8 and the fixing block 11 is used to lock the protective sleeve 1 on top of the protective sleeve 1, which can prevent stones, soil and garbage from entering the foundation pit and affecting the structural performance of the subsequent pile foundation. The limiting groove 9 and the limiting block 10 are used to further restrict the fixing block 11, forming a damping effect to prevent the waterproof board 2 from easily falling off the protective sleeve 1.

[0038] When pouring cement into the foundation pit to form a pile foundation, the retractable protective sleeve 1 can be pulled up and opened to form a cavity that can accommodate the cement. After the cement solidifies, it will automatically form a pile foundation structure protruding above the foundation pit. There is no need to use additional surrounding panels to build a cement formwork structure, which is convenient and quick. The setting of the reinforcing rib 3 can improve the stability of the protective sleeve 1 before the cement solidifies and further improve the firmness of the pile foundation after the cement solidifies.

[0039] The protective sleeve 1, with its fixed shape to the cement, can, in conjunction with the waterproof membrane 2, provide shelter from wind and rain before the cement hardens, preventing damage to the pile foundation caused by rainwater erosion and wind erosion, thus avoiding economic losses. Furthermore, because the protective sleeve 1 is retractable, and the annular block 4, corresponding to the inner side of the annular groove 7, has a sunken structure, the protective sleeve 1 and waterproof membrane 2 can be stored inside the annular groove 7 before use, facilitating storage and transport and improving the convenience of photovoltaic operations.
