Description

A pre-embedded rod seat

technical field

The invention relates to the field of substation equipment, in particular to a pre-embedded inserting pole seat.

Background technique

At present, there are two types of fixing rods commonly used in domestic substations. One is to fix by the metal cone tip at the bottom, insert the cone tip into the soil, and insert the rod into the metal cone to fix it; pole. Due to the arrangement of safety measures in the substation, the insertion rod with a metal cone tip is only suitable for the grass and mud field, and cannot be used for the cement ground; and the insertion rod fixed by the metal chassis cannot be used in the substation in a mountainous area with a slope or the settlement is serious. site use. Generally speaking, due to the different surface conditions in each area of the substation, one standard cannot be used to meet all needs, resulting in inconsistent standards for the insertion rods for safety measures in the substation, inconvenient use, and a large and time-consuming workload for arranging safety measures. The actual effect is not good.

Contents of the invention

The object to be achieved by the present invention is to provide a pre-embedded inserting rod seat, which is applicable to various terrains.

In order to achieve the above object, the present invention adopts the following technical solutions: a pre-embedded rod holder, including a connecting part and a mounting part, the connecting part and the mounting part are fixed or integrated; the connecting part is provided with a vertical shaft for connecting the rod Straight connection hole; the installation part is arranged below the ground, and a vertical inner hole is arranged in the installation part, and the inner hole communicates with the connection hole, and a limit pin for limiting the insertion depth of the insertion rod is arranged in the inner hole.

Further, it also includes an anti-sinking sheet, the anti-sinking sheet is arranged around the side of the connecting part, and the lower surface of the anti-sinking sheet is against the ground, which can prevent the connecting part from sinking below the ground with the installation part.

Further, it also includes a cover, which is arranged on the connection part and can move relative to the connection part, and the cover can move to the connection hole and cover the connection hole to close the connection hole. Prevent rainwater, debris, etc. from entering the connection hole and blocking the connection hole when the rod seat is not in use.

Further, the cover is rotatably connected to the connecting part, and a torsion spring is provided at the junction between the cover and the connecting part to keep the cover in a tendency to cover the connecting hole. The cover can automatically close the connection hole to prevent personnel from forgetting.

Further, the installation part is provided with a drainage hole penetrating through the inner hole wall and the outer wall of the installation part, which can drain the water in the connection hole of the rod seat and the inner hole.

Further, the end of the installation part is pointed. Easy to install.

Further, the distance between the limit pin and the top of the connecting hole is 19-20cm. After inserting the insertion rod into the connecting hole, it further enters the inner hole and is positioned at the limit pin. The insertion depth is 19-20cm, which is wind-resistant. The performance is strong and there is no need to lengthen the original insertion rod.

After adopting the technical scheme, the present invention has the following advantages:

It can be applied to various terrains such as hard ground and sloping ground, reducing the demand for equipment types in substations. At the same time, it can realize the mutual use of equipment in various substations, reducing the cost of substations.

Description of drawings

The present invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is the schematic diagram of a kind of embodiment of the present invention;

Fig. 2 is the top view of the embodiment shown in Fig. 1;

Fig. 3 is a cross-sectional view of the embodiment shown in Fig. 1 .

Detailed ways

Figures 1-3 show an embodiment of the present invention.

A pre-embedded rod holder, comprising a connecting part 1 and a mounting part 2, the connecting part 1 and the mounting part 2 are integrally structured, the connecting part 1 has a vertical connecting hole 6, and the mounting part 2 has a vertical inner hole Hole 8, the connection hole 6 and the inner hole 8 are connected, and the inner hole 8 is equipped with a transverse limit pin 7. When the insertion rod is inserted into the connection hole 6 of the connection part 1, the part exceeding the connection hole 6 enters the inner hole 8 and finally limits it. Position pin 7 is positioned, and the distance between limit pin 7 and the top of connecting hole 6 is 19.5cm, which has strong wind resistance and does not need to lengthen the original insertion rod. The side of the connection part 1 is provided with an anti-sinking sheet 5, the anti-sinking sheet 5 surrounds the connection part 1, and the lower bottom surface is against the ground to prevent the connection part 1 from sinking below the ground with the installation part 2. A cover 3 is rotatably connected to the connecting part 1, and a torsion spring 4 is installed at the junction between the cover 3 and the connecting part 1. The torsion spring 4 generates elastic force to make the cover 3 turn to the connection hole 6, and the cover 3 can be turned to the connection hole 6 and cover the connection hole 6 to prevent rainwater, sundries, etc. from entering the connection hole 6 when the rod holder is not in use. The side of the mounting part 2 is provided with a drainage hole 9, and the drainage hole 9 communicates with the inner hole 8 so as to discharge the water and small debris in the connection hole 6 and the inner hole 8. The end of the installation part 2 is tapered, thereby reducing the installation difficulty of the plunger seat.

This pre-embedded rod holder can be applied to various terrains such as hard ground and sloping ground, which reduces the demand for equipment types in substations, and at the same time enables the mutual use of equipment in various substations, reducing the cost of substations.

Except above-mentioned preferred embodiment, the present invention also has other embodiments, and those skilled in the art can make various changes and deformations according to the present invention, as long as they do not depart from the spirit of the present invention, all should belong to the scope defined in the appended claims of the present invention scope.
