Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic ground piles, and in particular relates to a photovoltaic ground pile spiral drill rod device. Background Art

[0002] The photovoltaic industry, abbreviated as PV, is an industrial chain that converts sunlight directly 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 demonstrate rapid technological iteration capabilities, continuously improve conversion efficiency, continuously optimize cost-effectiveness, and continuously enhance market competitiveness. The photovoltaic industry mainly includes the production of high-purity polysilicon raw materials, solar cell production, solar cell module production, the manufacture of related production equipment, and the application of photovoltaic power generation. Among them, photovoltaic silicon materials, silicon wafers, battery cells, and modules are the four main links. The photovoltaic industry is a key component of global energy transformation and sustainable development, and is of great significance to reducing carbon emissions and promoting the development of green energy.

[0003] Photovoltaic ground piles are the basic structures used to fix and support photovoltaic panels or brackets in solar photovoltaic systems. They are designed to maximize the power generation efficiency of solar panels and ensure that the system remains stable under various environmental conditions. Photovoltaic ground piles are made of various materials, the most common of which are galvanized steel plates, stainless steel, aluminum alloys, etc. These materials each have their own advantages and disadvantages. For example, galvanized steel plates have good corrosion resistance, durability and machinability, but the zinc layer is thin and may not be suitable for long-term use in humid environments; stainless steel has stronger corrosion resistance and a longer service life, but the cost is higher; aluminum alloy has the advantages of light weight, high strength and corrosion resistance, but the cost is also relatively high. In recent years, new lightweight and high-strength materials such as glass fiber reinforced plastic (GFRP) and carbon fiber reinforced plastic (CFRP) have also been gradually used in the manufacture of photovoltaic ground piles. These materials not only have higher strength, but also are light weight, corrosion-resistant and weather-resistant.

[0004] The photovoltaic ground pile spiral drill rod device firmly fixes the photovoltaic panel to the ground through its sturdy support. This fixing method not only ensures the stable operation of the photovoltaic panel, prevents damage and displacement caused by natural factors such as wind and rain, but also helps to extend the service life of the photovoltaic panel. As the core component of photovoltaic power generation, the stability and reliability of the photovoltaic panel are directly related to 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 coaxially arranged motor, an auger rod, a drill bit, a positioning sleeve one and a positioning sleeve two. The upper end of the auger rod is connected to the output end of the motor, and the lower end is connected to the drill bit. The positioning sleeve is set on the outside of the auger rod, and the positioning sleeve two is set on the outside of the positioning sleeve one. The upper end of the positioning sleeve two is fixedly connected to the motor, and the lower end is slidably connected to the positioning sleeve one. A spring is provided between the positioning sleeve one and the positioning sleeve two. A positioning plate is provided at the end of the positioning sleeve one, and the positioning plate is perpendicular to the axis of the positioning sleeve one. Through the fixed connection between the positioning sleeve two and the motor, the direction of the positioning sleeve one is guaranteed by the positioning plate, and the guiding effect of the coaxial positioning sleeve one and the positioning sleeve two, it is ensured that the movement direction of the auger rod is always perpendicular to the drilled ground, effectively preventing the drilling direction from deviating, and having the advantages of simple structure, small size and easy use.

[0006] Compared with the above documents, in the above documents, although the fixed connection between the positioning sleeve 2 and the motor, the direction of the positioning sleeve 1 is guaranteed by the positioning plate, and the guiding effect of the coaxial positioning sleeve 1 on the positioning sleeve 2 is used to ensure that the movement direction of the spiral drill rod is always perpendicular to the drilled ground, effectively preventing the drilling direction from deviating, and having the advantages of simple structure, small size and easy use, the demand for spiral drill rods is increasing due to the development of the photovoltaic industry. During the drilling operation, dust is easily flying during the drilling process, which increases the dust concentration in the air and reduces the quality of the workers' working environment. In addition, during the drilling process, due to the friction and impact of the drill bit, a higher temperature will be generated, thereby reducing the service life of the drill bit. For this reason, a photovoltaic ground pile spiral drill rod device is proposed.

[0007] In order to solve the above problems, the appropriate drill rod structure was matched according to the geological conditions of the drilling hole, and the structure of the drill rod itself was targeted for research and development and improvement. Finally, a photovoltaic ground pile spiral drill rod device with excellent performance in various geological conditions and excavation efficiency was developed and improved. Utility Model Content

[0013] By utilizing the function of the atomizing screen, the sprayed water can be sprayed in an atomized state, thereby increasing the coverage of the water spray inside the drill rod shaft and improving the wetting effect of the soil on the outer wall of the drill rod shaft;

[0014] By fitting the baffle, the outer wall of the water outlet can be blocked, and only the water spraying position is leaked, which can reduce the soil from entering the interior of the water outlet and clogging it. In addition, the rotation of the drill rod shaft can rotate and detach the soil attached to the outer wall of the water outlet, further avoiding the blockage of the water outlet and improving the water outlet efficiency of the water outlet.

[0015] Preferably, the atomizing screen and the sliding rod are arranged to slide.

[0016] Preferably, the outer side wall of the fitting baffle and the inner side wall of the water outlet are arranged to be slidingly fitted.

[0017] Preferably, the outer wall diameter of the sliding rod is smaller than the inner wall diameter of the water outlet.

[0018] Preferably, a water inlet is provided at the top of one side of the outer wall of the drill rod shaft.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By rotating the water outlet mechanism, during drilling operations, the dust raised can be moistened and knocked down by spraying water on the outer wall of the drill rod shaft, reducing the dust concentration in the air and improving the quality of the workers' working environment. In addition, during the drilling process, water can be sprayed onto the outer walls of the drill bit and drill rod head to reduce the temperature generated there, thereby extending the service life of the drill bit and drill rod head.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-3 As shown, the photovoltaic ground pile spiral drill rod device includes: a connecting flange 1, a drill rod shaft 2, a spiral blade 3, a ground-breaking drill bit 4 and a drill rod head 5. The connecting flange 1 is fixedly mounted on one end of the drill rod shaft 2, the drill rod head 5 is fixedly connected to the other end of the drill rod shaft 2, the outer wall of the drill rod shaft 2 is connected to the spirally wound spiral blade 3, and the ground-breaking drill bit 4 is fixedly connected to the outer wall of the drill rod shaft 2;

[0030] like Figure 1-3 As shown, the interior of the drill rod shaft 2 is hollow, and a rotating water outlet mechanism is connected to the interior of the drill rod shaft 2 for spraying water on its outer wall when the drill rod shaft 2 is working. The rotating water outlet mechanism includes a plurality of water outlets 201 provided on the outside of the bottom of the drill rod shaft 2. Tension springs 202 are fixedly connected to the inner wall of the drill rod shaft 2 on both sides of the water outlet 201. A sliding rod 203 is fixedly connected between the two tension springs 202. A fitting baffle 204 is fixedly connected to one end of the sliding rod 203. An atomizing mesh plate 205 is fixedly connected to the interior of the water outlet 201.

[0031] The present invention is further specifically described in detail. The atomizing screen 205 and the sliding rod 203 are slidingly arranged. The outer wall of the fitting baffle 204 and the inner wall of the water outlet 201 are slidingly fitted. The outer wall diameter of the sliding rod 203 is smaller than the inner wall diameter of the water outlet 201. A water inlet is opened on the top of one side of the outer wall of the drill rod shaft 2. The material of the drill rod shaft 2 is a seamless steel pipe.

[0032] As can be seen from the above, when the drill rod shaft 2 is drilling, the water outlet 201 on its outer wall is driven to rotate. According to the action of the centrifugal force of the rotation, the fitting baffle 204 can slide outward according to the sliding action of the sliding rod 203 and separate from the water outlet 201. At this time, the water inside the drill rod shaft 2 can be rotated and sprayed out through the atomizing mesh plate 205 to moisten the soil around the drill rod shaft 2, thereby increasing the force of the spiral blades 3 on the outer wall of the drill rod shaft 2 to rotate and drill holes in the soil. Through the setting of this structure, during the drilling operation, according to the action of the water spraying on the outer wall of the drill rod shaft 2, the dust raised can be moistened and knocked down, thereby reducing the dust concentration in the air and improving the working environment quality of the workers. In addition, during the drilling process, water can be sprayed to the outer walls of the earth-breaking drill bit 4 and the drill rod head 5 to reduce the temperature generated therein, thereby improving the service life of the earth-breaking drill bit 4 and the drill rod head 5.

[0033] By utilizing the function of the atomizing screen 205, the sprayed water can be sprayed in an atomized state, thereby increasing the coverage of the water spray inside the drill rod shaft 2 and improving the wetting effect of the soil on the outer wall of the drill rod shaft 2;

[0034] By fitting the baffle 204, the outer wall of the water outlet 201 can be blocked, and only the water spraying position is exposed, which can reduce the soil from entering the interior of the water outlet 201 and clogging it. In addition, the rotation of the drill rod shaft 2 can rotate and detach the soil attached to the outer wall of the water outlet 201, further avoiding the blockage of the water outlet 201 and improving the water outlet efficiency of the water outlet 201.

[0035] Furthermore, this design application is applied to the field of photovoltaic ground pile spiral drill rods. During the drilling operation, the raised dust can be moistened and knocked down based on the effect of spraying water on the outer wall of the drill rod shaft 2, reducing the dust concentration in the air and improving the working environment quality of the workers. The outer walls of the earth-breaking drill bit 4 and the drill rod head 5 can be sprayed with water to cool them down, thereby improving the service life of the earth-breaking drill bit 4 and the drill rod head 5.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
