Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a grounding pile structure for power engineering. Background Technology

[0002] The grounding pile structure in power engineering is an important component in power systems and electrical installations that connects the neutral point, the exposed conductive parts of electrical equipment, and the external conductive parts of the equipment to the earth via conductors. It is mainly divided into working grounding, lightning protection grounding, and protective grounding.

[0003] Most of the grounding pile structures used in current power engineering are fixed in the form of fishhooks. Although this structure can make the grounding pile more stable after installation, it has the problem that the extended part cannot be limited after insertion, resulting in insufficient stability when the grounding pile is subjected to a large upward lifting force. At the same time, it requires manual support during pile driving. Utility Model Content

[0013] This utility model provides a grounding pile structure for power engineering, which has the following beneficial effects:

[0014] 1. The grounding pile structure of this power engineering project, through the setting of the depth line, enables the grounding pile structure to accurately locate the required hammering depth. Through the cooperation of the outer shell and the support plate, the support plate can provide support after the fixed head is inserted into the ground during use. This allows the support plate to slide along the groove and support the grounding pile body during hammering insertion, preventing accidental displacement caused by manual hammering and thus improving the safety of the device.

[0015] 2. The grounding pile structure of this power engineering project, through the setting of the clamp rod, enables the clamp rod to pop out after the fixing plate is unfolded, thus limiting the fixing plate. Through the cooperation of the fixing plate and the baffle, during use, when the grounding pile body is hammered downward after the outer shell is pulled out, the resistance provided by the baffle causes the fixing plate to unfold slightly outward. Then, the resistance of the soil on the fixing plate causes the fixing plate to fully unfold until the clamp rod pops out. This increases the contact area between the fixing head and the soil, making the installation of the grounding pile body more stable. This achieves the purpose of improving the stability of the grounding pile body installation by increasing the contact area between the fixing end and the soil. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] Please see Figures 1 to 6 The present invention provides a technical solution: a grounding pile structure for power engineering, including a grounding pile body 1, a shell 2 slidably connected to the outer surface of the grounding pile body 1, a hammering surface 3 fixedly connected to the upper end of the shell 2, a fixing block 4 fixedly installed on the outer surface of the shell 2, a sliding groove 401 opened inside the fixing block 4, a support rod 5 slidably connected inside the sliding groove 401, a support plate 6 fixedly installed below the support rod 5, a fixing head 7 fixedly connected to the lower part of the grounding pile body 1, and a fixing plate 8 rotatably connected to the outer surface of the fixing head 7.

[0026] Specifically, the design of the support rod 5 and the sliding groove 401 allows the support plate 6 to contact the ground for support when the hammer shell 2 moves downward. It can also slide along the sliding groove 401 during the hammering process, thereby avoiding manual support and preventing the hammer from deviating and causing injury to the construction personnel. The design of the fixing plate 8 and the clamping rod 10 allows the fixing plate 8 to be limited by the clamping rod 10 after it unfolds in the soil after being hammered, thereby increasing the contact area between the device and the soil and the stability of the installation.

[0027] Please see Figures 1 to 4A connector 101 is fixedly connected to the side of the grounding stake body 1. A connector groove 201 matching the connector 101 is opened on the side of the outer shell 2. A depth line 102 is provided on the outer surface of the grounding stake body 1. The lower end of the fixing block 4 is designed with a chamfer. There are several fixing blocks 4. The several fixing blocks 4 are evenly distributed on the outer surface of the outer shell 2 in a circular array. The uppermost end of the fixing block 4 is located below the depth line 102 on the outer surface of the grounding stake body 1.

[0028] Specifically, by setting the depth line 102, the grounding pile structure of the power project can accurately locate the required hammering depth of the grounding pile. During the hammering process, the terminal 101 will also slide along the terminal slide groove 201, thereby avoiding damage to the terminal 101. Through the cooperation of the outer shell 2 and the support plate 6, the support plate 6 can provide support after the fixed head 7 is inserted into the ground during use. This allows the support plate 6 to slide along the slide groove 401 to provide support during the hammering and insertion of the grounding pile body 1, preventing accidental displacement caused by manual hammering and thus improving the safety of the device.

[0029] Please see Figures 2 to 6 The lower end of the fixing head 7 is tapered, and an installation groove is provided inside the fixing head 7. The cross-sectional shape of the installation groove is convex. There are several installation grooves, which are arranged in a circular array inside the fixing head 7. A spring 9 is installed inside the installation groove. One end of the spring 9 is fixedly connected to a clamping rod 10. The outer diameter of the fixing plate 8 is the same as the diameter of the grounding pile body 1, and the outer diameter of the fixing plate 8 is the same as the inner diameter of the outer shell 2. There are several fixing plates 8, which are evenly distributed in a circular array on the outer surface of the fixing head 7. A rotating shaft 801 is fixedly connected to the upper end of the fixing plate 8. The rotating shaft 801 is rotatably connected to the inside of the fixing head 7. A baffle 803 is fixedly connected to the front of the fixing plate 8. A fixing plate mating groove 802 is provided on the upper surface of the fixing plate 8. The fixing plate mating groove 802 matches the size and shape of the clamping rod 10.

[0030] Specifically, the setting of the clamp 10 enables the grounding pile structure of the power project to have the effect of allowing the clamp 10 to pop out after the fixing plate 8 is unfolded, thus limiting the fixing plate 8. Through the cooperation of the fixing plate 8 and the baffle 803, during use, when the grounding pile body 1 is hammered downward after the outer shell 2 is pulled out, the resistance provided by the baffle 803 causes the fixing plate 8 to unfold slightly outward. Then, the resistance of the soil on the fixing plate 8 causes the fixing plate 8 to fully unfold until the clamp 10 pops out, thereby increasing the contact area between the fixing head 7 and the soil, making the installation of the grounding pile body 1 more stable. This achieves the purpose of increasing the contact area between the fixing end and the soil, thus improving the stability of the installation of the grounding pile body 1.

[0031] In use, first insert the fixing head 7 into the ground. After insertion, the two support plates 6 will contact the ground and provide support. When hammering, only the hammering surface 3 needs to be hammered. The support plates 6 will remain in contact with the ground and provide support because the support rod 5 slides in the groove 401. During the hammering process, the connector 101 will also slide along the connector groove 201, thus avoiding damage to the connector 101. When the support rod 5 reaches the top of the groove 401 through hammering, the outer shell 2 can be pulled out through the hammering surface 3. At this time, since the grounding stake body 1 has been hammered into a relatively deep position, there is no need to continue hammering without assistance. After the hammer strikes, due to the lack of a limiting position on the fixing plate 8, the resistance from the soil to the fixing plate 8 and the baffle 803 on the front of the fixing plate 8 will cause the fixing plate 8 to expand outwards during the hammer strike. When the fixing plate mating groove 802 rotates to the locking rod 10, the spring 9 will push the locking rod 10 out and insert it into the fixing plate mating groove 802, thereby limiting the fixing plate 8 and keeping it perpendicular to the fixing head 7. This increases the contact area with the soil and improves the stability of the grounding pile body 1 during installation. After installation, the cables to be connected can be connected to the connector 101. If other grounding pile bodies 1 need to be installed, the outer shell 2 can be reused for installation.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
