AI Technical Summary
When installing heliostat columns on gravel foundations, it is difficult for existing drilling devices to effectively remove gravel blocks, resulting in high cost of hole formation and a large number of manual hole cleaning. At the same time, the existing devices need to add water in real time to form a protective wall during the drilling process, which increases the construction difficulty.
A quick hole-forming drilling rod for gravel-based heliostat columns is designed. Water spraying technology is used to spray water into the hole during the drilling process, so that the gravel and soil are fully stirred to form adhesive slag, which is easy to remove through the threaded disk, and at the same time, a protective wall is formed during the drilling process to enhance the strength of the hole wall.
It effectively avoids gravel blocks from staying in the holes, reduces the hole cleaning work after hole formation, reduces the cost of hole formation, and forms a wall protection by spraying water, reducing the workload and water addition frequency of construction workers.

Technical Field
[0001] The utility model relates to the technical field of photothermal engineering, and in particular to a quick-hole drilling rod for a heliostat column on a gravel foundation. Background Art
[0002] Solar thermal projects are gradually showing their huge potential and value. As an important part of renewable energy, solar thermal power generation technology uses a concentrating solar collector system to collect and reflect sunlight, heat the molten salt to 565°C, store the heat energy through a molten salt energy storage system, and then use a steam power generation system to generate electricity. The concentrating solar collector system usually consists of tens of thousands of heliostats that reflect and concentrate sunlight to heat the heat storage medium in the collector. The heliostat field of a solar thermal project is composed of multiple heliostats, which need to be supported by heliostat columns. When installing the heliostat columns, you first need to drill holes in the ground and then install the heliostat columns.

[0003] The existing drilling device drives the drill rod to drill a hole through a motor, and a threaded disk is fixedly mounted on the outside of the drill rod. When drilling a hole, soil will be retained in the threaded disk. After the drilling is completed, the drill rod is lifted up, and the soil retained on the threaded disk is cleaned out of the formed drill hole along with the drill rod. The above-mentioned drilling device has a good effect when drilling holes in common soils, but there are still some problems when used in some specific areas. For example, when drilling holes in gravel ground, there are some broken stones mixed in the soil. If the above-mentioned drilling device is used for drilling, when the drill rod is taken out, the stones retained on the threaded disk will roll when the drill rod is lifted up because the stones are different from the soil, and the stones will roll out of the threaded disk. The sand and soil in the hole are mixed with the water to form a protective wall around the hole, which will further increase the workload of the construction workers.

At this time, the broken stones and excess soil generated during the drilling process will be retained on the threaded disk 9. When the drill rod 8 is lifted after the drilling work is completed, the provided stopper 10 blocks the broken stones retained on the threaded disk 9 to prevent the broken stones from falling into the borehole when the drill rod 8 is lifted, and there is no need to clean the hole again. In addition, the water pipe 6 directly conveys the water flow to the drill rod 8, and sprays the water flow through the water spray hole 11 on the drill rod 8. When drilling, the gravel, soil and water in the hole are fully mixed and have a certain cohesiveness. The slag in the hole can be smoothly taken out by reversing the threaded disk 9. At the same time, a layer of protective wall is formed around the borehole when the water flow and soil are mixed. There is no need for construction personnel to add water in real time, which saves a lot of labor and reduces the cost of drilling.
[0026] When drilling, water flows out from the drill rod 8, and water and soil form a protective wall around the borehole during the drilling process. The block 10 is set as an arc block.

The first gear 51 meshes with the second gear 52 to rotate, and drives the set third gear 53 to rotate under the action of the connecting rod 55. The third gear 53 meshes with the fourth gear 54, so that the fourth gear 54 drives the set installation rod 13 to rotate, and drives the set drill rod 8 to rotate under the action of the flange 4. There is a gap between the first gear 51 and the fourth gear 54.
