TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic ground pile technical field, concretely relates to the vane wear -resisting structure of photovoltaic ground pile spiral drill rod. BACKGROUND

[0002] The photovoltaic industry, abbreviated as PV, is an industry chain that directly converts sunlight into electrical energy based on the application and development of silicon materials. As an important part of the new energy field, the photovoltaic industry has important characteristics such as innovation, flexibility, renewability, and cleanliness. Its continuous innovation enables the photovoltaic industry to exhibit rapid technical iteration capabilities, continuously improve conversion efficiency, continuously optimize cost-effectiveness, and continuously enhance market competitiveness. The photovoltaic industry mainly includes high-purity polycrystalline silicon raw material production, solar cell production, solar cell module production, related production equipment manufacturing, and photovoltaic power generation applications. Among them, photovoltaic silicon material, silicon wafer, cell piece, and module are the four main links. The photovoltaic industry is a key component of global energy transformation and sustainable development, and it is of great significance for reducing carbon emissions and promoting green energy development.

[0003] The photovoltaic ground pile is a foundation structure used to fix and support photovoltaic panels or brackets in a solar photovoltaic system. Its design aims to maximize the power generation efficiency of solar panels and ensure the stability of the system under various environmental conditions. The material of the photovoltaic ground pile is diverse, with common materials including galvanized steel sheet, stainless steel, aluminum alloy, etc. These materials have their own advantages and disadvantages. For example, galvanized steel sheet has good corrosion resistance, durability, and processability, but the zinc layer is relatively thin and may not be suitable for long-term use in humid environments. Stainless steel has stronger corrosion resistance and longer service life, but the cost is higher. Aluminum alloy has the advantages of light weight, high strength, corrosion resistance, etc., but the cost is also relatively high. In recent years, new lightweight high-strength materials such as glass fiber reinforced plastic (GFRP) and carbon fiber reinforced plastic (CFRP) have gradually been applied in the manufacturing of photovoltaic ground piles. These materials not only have higher strength, but also are light in weight, corrosion-resistant, and weather-resistant.

[0004] The photovoltaic ground pile spiral drill rod device firmly fixes the photovoltaic panel on the ground through its strong support, which not only ensures the stable operation of the photovoltaic panel and prevents damage and displacement caused by natural factors such as wind and rain, but also helps to prolong the service life of the photovoltaic panel. As the core component of photovoltaic power generation, the stability and reliability of the photovoltaic panel directly affect the power generation efficiency and service life of the entire photovoltaic system.

[0005] In the Chinese patent with publication number CN218716536U, a photovoltaic pile foundation construction positioning device is mentioned, which includes a motor, a spiral drill rod, a drill bit, a positioning sleeve one and a positioning sleeve two arranged coaxially. The upper end of the spiral drill rod is connected with the motor output end, the lower end is connected with the drill bit, the positioning sleeve one is sleeved outside the spiral drill rod, the positioning sleeve two is sleeved outside the positioning sleeve one, the upper end of the positioning sleeve two is fixedly connected with the motor, the lower end is slidingly connected with the positioning sleeve one, a spring is arranged between the positioning sleeve one and the positioning sleeve two, the end of the positioning sleeve one is provided with a positioning plate, and the positioning plate is perpendicular to the axis of the positioning sleeve one. Through the fixed connection of the positioning sleeve two and the motor, the direction guarantee of the positioning plate to the positioning sleeve one, and the guiding effect of the coaxial positioning sleeve one to the positioning sleeve two, the movement direction of the spiral drill rod is always perpendicular to the drilled ground, the drilling direction deviation is effectively prevented, and the device has the advantages of simple structure, small size and convenient use.

[0006] In the above-mentioned file, although the fixed connection of the positioning sleeve two and the motor, the direction guarantee of the positioning plate to the positioning sleeve one, and the guiding effect of the coaxial positioning sleeve one to the positioning sleeve two, the movement direction of the spiral drill rod is always perpendicular to the drilled ground, the drilling direction deviation is effectively prevented, and the device has the advantages of simple structure, small size and convenient use, due to the development of photovoltaic industry, the demand for spiral drill rods is increasing. However, a single spiral drill rod device cannot efficiently adapt to the geological characteristics of some regions, and problems such as rapid wear of the drill rod spiral blade occur, which is not conducive to the work personnel to break the soil and drill holes for the photovoltaic ground pile, and reduces the work efficiency of the work personnel to break the soil and drill holes for the photovoltaic ground pile. Therefore, a photovoltaic ground pile spiral drill rod blade wear-resistant structure is proposed.

[0007] To solve the above-mentioned problems, the drill rod structure is matched according to the drilling geological conditions, and the structure of the drill rod itself is developed and improved, and finally the photovoltaic ground pile spiral drill rod blade wear-resistant structure with excellent geological conditions and tunneling efficiency is developed and improved. The utility model discloses a photovoltaic ground pile spiral drill rod blade wear-resistant structure.

The connecting flange is fixedly installed at one end of the drill rod shaft. The drill rod head is fixedly connected to the other end of the drill rod shaft. The outer wall of the drill rod shaft is connected with a spiral blade wound spirally. The soil breaking drill bit is fixedly connected to the outer wall of the drill rod shaft. The outer wall of the spiral blade is welded with a wear-resistant welding rod.

[0013] By setting the thickness of the connecting flange to 25mm, the torque of the connecting flange is increased, and the stronger torque transmission capability means that the transmission system can more effectively transmit power from one place to another, reducing energy loss and improving overall transmission efficiency.

[0014] The wear-resistant drill rod shaft can better resist the friction and wear of the soil during soil drilling, thereby prolonging the service life of the drill rod shaft, which means that the frequency of replacing the drill rod shaft is reduced, the operation cost is reduced, and the operation efficiency is improved.

[0015] As the use time increases, the surface of the drill rod shaft will gradually thin due to wear, which may cause the strength and stiffness of the drill rod shaft to decrease, thereby affecting its drilling effect. Increasing the wear resistance of the drill rod shaft can slow down the wear rate of the drill rod shaft surface, maintain the performance stability of the drill rod shaft, and ensure the smooth progress of the drilling operation.

[0016] During soil drilling, the drill rod shaft may encounter various types of soil, including soil containing hard particles, high humidity or high viscosity. These soil conditions may cause significant wear to the drill rod shaft. Increasing the wear resistance of the drill rod shaft can make the drill rod shaft better adapt to these harsh operating environments, reducing downtime and downtime due to wear.

[0017] The wear-resistant drill rod shaft can maintain good shape and dimensional accuracy during drilling, thereby ensuring the efficiency and quality of the drilling operation, which helps to reduce hole diameter deviation, hole wall roughness and other problems caused by drill rod shaft wear, and improves the accuracy and stability of the drilling.

[0018] Preferably, the material of the wear-resistant welding rod is one of high-chromium alloy cast solid core welding wire, cobalt-based alloy, nickel-based alloy or tungsten carbide surfacing welding rod.

[0019] Preferably, the connecting flange is connected to the front end of the drill rod shaft and is the hand holding position of the worker, and the drill rod head is located at the rear end of the drill rod shaft and is the breaking soil position of the drill rod shaft.

[0020] Preferably, the spiral blade is located between the connecting flange and the drill rod head.
