Description

Technical Field

[0001] This utility model relates to the field of soil resistance reduction technology, and in particular to a grounding soil resistance reduction device for photovoltaic booster stations. Background Technology

[0002] In the grounding system of photovoltaic booster stations, there are sometimes situations where the soil resistance is high, which may affect the grounding effect and the safety performance of the equipment. Therefore, resistance reduction operations are usually performed on the grounding soil.

[0003] Existing soil resistance reduction methods mainly involve increasing the length of the grounding electrode and adding resistance-reducing agents. Increasing the length of the grounding electrode increases the contact area with the soil, thereby reducing the resistance of the grounding system. Adding resistance-reducing agents involves adding chemical substances to the soil to improve its conductivity, thus reducing the resistance of the grounding system. However, these existing methods require manual mixing of the resistance-reducing agent, pouring it into the designated location, and manually driving the grounding electrode head into the soil. This involves a large amount of work and a long construction time. Therefore, it is necessary to design a soil resistance reduction device for photovoltaic booster stations to solve the above problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0031] The conductive concrete column 1 is buried in the soil of the photovoltaic booster station. The conductive concrete column 1 is equipped with a construction mechanism. It should be noted that the construction mechanism can automatically stir the resistance-reducing agent without manual stirring, and can also automatically drive the grounding electrode head 4 into the soil of the photovoltaic booster station, which can effectively reduce the labor intensity of the staff.

[0032] The construction mechanism includes a lead screw 2, a moving plate 3, a grounding electrode head 4, a resistance reducing agent mixing tank 5, a power motor 6, a rotating shaft 7, a mixing blade 8, and a square insert 9;

The lead screw 2 is threadedly connected to the movable plate 3. The power motor 6 is fixedly mounted on the top of the drag-reducing agent mixing tank 5. The output end of the power motor 6 is fixedly connected to the rotating shaft 7. The bottom end of the rotating shaft 7 is fixedly connected to the square plug 9. The stirring blade 8 is fixedly mounted on the outside of the rotating shaft 7.

[0034] Using the aforementioned construction mechanism, the square plug 9 is inserted into the square slot 10, the power motor 6 is started, and the stirring blade 8 automatically stirs the resistance reducing agent without manual stirring. The rotating shaft 7 drives the lead screw 2 to rotate through the square plug 9. When the lead screw 2 rotates, the moving plate 3 can move the grounding electrode head 4 downward, thus automatically driving the grounding electrode head 4 into the soil of the photovoltaic booster station, which can effectively reduce the labor intensity of the workers.

[0035] Specifically, the construction mechanism also includes a protective cylinder 11, a stabilizing nail 12, and a threaded cylinder 13. The stabilizing nail 12 is fixedly installed at the bottom of the drag-reducing agent mixing tank 5, and the threaded cylinder 13 is fixedly installed on the bottom inner wall of the protective cylinder 11. The rotating shaft 7 has an external thread on its outer side.

[0036] The external thread is threaded to the threaded cylinder 13, and the top of the protective cylinder 11 is in contact with the drag-reducing agent mixing tank 5.

[0037] When the square plug 9 is inserted into the square slot 10 using the above-mentioned construction mechanism, the stable ground nail 12 can be inserted into the soil, improving the stability of the drag-reducing agent mixing tank 5. After mixing, the threaded cylinder 13 on the protective cylinder 11 can be screwed into the external thread on the rotating shaft 7. The protective cylinder 11 can shield the stable ground nail 12, thus improving the safety when pouring or carrying the drag-reducing agent mixing tank 5.

[0038] Specifically, the top of the lead screw 2 has a square slot 10, and the square plug 9 is adapted to the square slot 10. It should be noted that the square plug 9 can be inserted into the square slot 10.

[0039] Specifically, the movable plate 3 is vertically slidably installed inside the conductive concrete column 1. Two through holes are opened at the bottom of the conductive concrete column 1, and the grounding electrode head 4 contacts the inner wall of the through holes.

It should be noted that by holding the handle 14 with one hand and lifting the hand handle 15 with the other, the height of the hand handle 15 can be adjusted to facilitate pouring the mixed drag-reducing agent out through the material hole 16.

[0041] Working principle:

[0042] S1: First, the conductive concrete column 1 is pre-buried inside the grounding soil of the photovoltaic booster station.

The resistance reducing agent mixing box 5 is slowly placed downward so that the square plug 9 is inserted into the square slot 10 and the stable ground nail 12 can be inserted into the soil to improve the stability of the resistance reducing agent mixing box 5.

[0043] S2: Start the power motor 6, which drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the stirring blade 8 to rotate. The stirring blade 8 automatically stirs the drag-reducing agent without manual stirring. The rotating shaft 7 drives the lead screw 2 to rotate through the square plug 9. When the lead screw 2 rotates, it can cause the moving plate 3 to move the grounding electrode head 4 downward. In this way, the grounding electrode head 4 can be automatically driven into the soil of the photovoltaic booster station, which can effectively reduce the labor intensity of the staff.

[0044] S3: After the grounding electrode head 4 is driven into the soil of the photovoltaic booster station to a certain depth, the resistance reducing agent is also stirred. Then the resistance reducing agent mixing box 5 is removed and assembled with the protective cylinder 11. The protective cylinder 11 can shield the stable ground nail 12, which can improve the safety when pouring or carrying the resistance reducing agent mixing box 5.

[0045] S4: Hold the handle 14 in one hand and the handle 15 in the other. By adjusting the height of the handle 15, it is convenient to pour the mixed drag-reducing agent through the material hole 16 to the designated position. It is convenient to use and effectively reduces the workload.
