Description

Technical Field

[0001] This utility model relates to the field of spark prevention devices, and more specifically, to a spark prevention device for an oil depot storage area. Background Technology

[0002] A utility model patent with patent number CN202021485220.5 describes "An anti-sparking device for electrostatic grounding", which includes a lower limiting cylinder inserted into the ground; a limiting ring is provided at the top of the lower limiting cylinder, and a threaded ring is provided in the ground section inside the lower limiting cylinder; by setting a metal conductive rod body, mounting main board, threaded ring, circular groove, fixing nail, vertical limiting cylinder, limiting ring and lower limiting cylinder, the lower limiting cylinder can be inserted into the ground and the metal conductive rod body is inserted into the lower limiting cylinder and then into the ground. At the same time, the mounting main board, fixing nail and vertical limiting cylinder fix and limit the metal conductive rod body, making it more firmly fixed to the ground. At the same time, the installation only requires inserting the lower limiting cylinder, metal conductive rod body, vertical limiting cylinder and fixing nail in sequence, and the overall installation process is also very simple.

[0003] However, in actual use, if the soil is relatively loose, the main body of the metal conductive rod will still be unstable and will easily sink, which further reduces the stability of the main body of the metal conductive rod. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a spark-proof device for oil depot storage areas. This device can prevent the main body of the metal conductive rod from sinking downwards during the installation of the spark-proof device, thereby improving the stability of the main body of the metal conductive rod.

[0006] Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A spark-proof device for an oil depot storage area includes a mounting main board. A metal conductive rod body is housed within the mounting main board. A vertical limiting cylinder is fixedly connected to the upper end of the mounting main board. The vertical limiting cylinder is located at the outer end of the metal conductive rod body and is threadedly connected to it. A threaded hole is drilled at the upper end of the metal conductive rod body, and a screw is threadedly connected to the threaded hole. A rubber pad is fixedly connected to the upper end of the screw. Two fixing screws symmetrical about the vertical limiting cylinder are threadedly connected to the upper end of the mounting main board. Multiple evenly distributed strip-shaped grooves are drilled at the outer end of the metal conductive rod body. A rotating shaft is fixedly connected between the two inner walls of each strip-shaped groove. A rotating bar is rotatably connected to the outer end of the rotating shaft. Two mutually symmetrical torsion springs are fixedly connected between the rotating bar and the inner wall of the strip-shaped groove. This design prevents the metal conductive rod body from sinking downwards during the installation of the spark-proof device, thereby improving the stability of the metal conductive rod body.

[0009] Furthermore, a first limiting ring is fixedly connected to the bottom end of the mounting motherboard. The first limiting ring is located on the outside of the metal conductive rod body. By setting the first limiting ring, the rotating bar on the metal conductive rod body can be restricted when the metal conductive rod body moves downward, thereby reducing the possibility that the rotating bar at the outer end of the metal conductive rod body will unfold and thus obstruct the downward movement of the metal conductive rod body.

[0010] Furthermore, a level tube is fixedly connected to the upper end of the mounting motherboard. The level tube is located outside the vertical limiting cylinder. By setting the level tube, technicians can easily check whether the metal conductive rod body is horizontal after the entire device is installed, thus facilitating subsequent adjustments by technicians.

[0011] Furthermore, multiple evenly distributed elastic strips are fixedly connected to the upper end of the mounting motherboard. The surface of each elastic strip is engraved with anti-slip textures. By setting the elastic strips and providing anti-slip textures, technicians are less likely to slip when installing the spark-proof device, thus improving their work efficiency. Furthermore, a second limiting ring is fixedly connected to the outer end of the metal conductive rod body. The second limiting ring is located on the upper side of the vertical limiting cylinder. By setting the second limiting ring, the metal conductive rod body is less likely to overextend into the vertical limiting cylinder. It also blocks the gap between the metal conductive rod body and the vertical limiting cylinder, thereby reducing the possibility of soil entering the gap and making it difficult for the metal conductive rod body to unscrew from the vertical limiting cylinder.

[0012] Furthermore, the outer end of the rotating bar is fixedly connected with multiple evenly distributed through holes. By setting through holes, the soil can be further screened when the rotating bar is unfolded, which facilitates the subsequent compaction of the soil. Beneficial effects

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) This solution can make the metal conductive rod body less likely to sink downwards when the spark extinguishing device is installed, thereby improving the stability of the metal conductive rod body.

[0015] (2) A first limiting ring is fixedly connected to the bottom of the mounting motherboard. The first limiting ring is located on the outside of the metal conductive rod body. By setting the first limiting ring, the rotating bar on the metal conductive rod body can be restricted when the metal conductive rod body moves downward, thereby reducing the possibility that the rotating bar at the outer end of the metal conductive rod body will unfold and thus the metal conductive rod body will be blocked from moving downward.

[0016] (3) A level tube is fixedly connected to the upper end of the main board. The level tube is located outside the vertical limiting cylinder. By setting the level tube, technicians can easily check whether the metal conductive rod body is horizontal after the entire device is installed, thus facilitating subsequent adjustments by technicians.

[0017] (4) Multiple evenly distributed elastic strips are fixedly connected to the upper end of the main board. The surface of the elastic strips is engraved with anti-slip texture. By setting elastic strips and setting anti-slip texture on their surface, technicians can avoid slipping when installing anti-sparking devices, thereby improving the work efficiency of technicians.

[0018] (5) A second limiting ring is fixedly connected to the outer end of the metal conductive rod body. The second limiting ring is located on the upper side of the vertical limiting cylinder. By setting the second limiting ring, the metal conductive rod body is less likely to enter the vertical limiting cylinder excessively. At the same time, it can also block the gap between the metal conductive rod body and the vertical limiting cylinder, thereby reducing the possibility of soil entering the gap between the metal conductive rod body and the vertical limiting cylinder, making it difficult for the metal conductive rod body to rotate out of the vertical limiting cylinder.

[0019] (6) Multiple evenly distributed through holes are fixedly connected to the outer end of the rotating bar. By setting through holes, the soil can be further screened when the rotating bar is unfolded, which makes the soil more compact when compacting it later. Attached Figure Description

[0029] Please refer to Figures 1-4. A spark-proof device for an oil depot storage area includes a mounting main board 1. A metal conductive rod body 2 is housed within the mounting main board 1. A vertical limiting cylinder 3 is fixedly connected to the upper end of the mounting main board 1. The vertical limiting cylinder 3 is located at the outer end of the metal conductive rod body 2 and is threadedly connected to it. A threaded hole 4 is drilled at the upper end of the metal conductive rod body 2. A screw 5 is threadedly connected to the threaded hole 4. A rubber pad 6 is fixedly connected to the upper end of the screw 5. Two symmetrical fixing screws 7 are threadedly connected to the upper end of the mounting main board 1 about the vertical limiting cylinder 3. Multiple evenly distributed strip grooves 8 are drilled at the outer end of the metal conductive rod body 2. A rotating shaft 9 is fixedly connected between the two inner walls of the strip grooves 8. A rotating strip 10 is rotatably connected to the outer end of the rotating shaft 9. Two symmetrical torsion springs 11 are fixedly connected between the rotating strip 10 and the inner wall of the strip grooves 8. This design prevents the metal conductive rod body from sinking downwards during the installation of the spark-proof device, thereby improving the stability of the metal conductive rod body.

[0030] Please refer to Figure 1-2. A first limiting ring 101 is fixedly connected to the bottom of the mounting main board 1. The first limiting ring 101 is located outside the metal conductive rod body 2. By setting the first limiting ring 101, the rotating bar 10 on the metal conductive rod body 2 can be restricted when it moves downwards, thereby reducing the possibility of the rotating bar 10 at the outer end of the metal conductive rod body 2 unfolding and obstructing its downward movement. A level tube 102 is fixedly connected to the upper end of the mounting main board 1. The level tube 102 is located outside the vertical limiting cylinder 3. By setting the level tube 102, technicians can easily check whether the metal conductive rod body 2 is horizontal after the entire device is installed, thus facilitating subsequent adjustments. Multiple evenly distributed elastic strips 103 are fixedly connected to the upper end of the mounting main board 1. The surface of the elastic strips 103 is engraved with anti-slip textures. By setting the elastic strips 103... Furthermore, the surface is textured with anti-slip patterns, which makes it less likely for technicians to slip when installing spark-proof devices, thereby improving their work efficiency.

[0031] Please refer to Figure 2-4. A second limiting ring 201 is fixedly connected to the outer end of the metal conductive rod body 2. The second limiting ring 201 is located on the upper side of the vertical limiting cylinder 3. By setting the second limiting ring 201, the metal conductive rod body 2 is less likely to excessively enter the vertical limiting cylinder 3. At the same time, it can also block the gap between the metal conductive rod body 2 and the vertical limiting cylinder 3, thereby reducing the possibility of soil entering the gap between the metal conductive rod body 2 and the vertical limiting cylinder 3, making it difficult for the metal conductive rod body 2 to rotate out of the vertical limiting cylinder 3. The outer end of the rotating bar 10 is fixedly connected with multiple evenly distributed through holes 1001. By setting the through holes 1001, when the rotating bar 10 is unfolded, the soil can continue to be screened, which facilitates the subsequent compaction of the soil.

[0032] When using this invention, technicians place the mounting motherboard 1 on the ground and bury the first limiting ring 101 below the ground. The technicians then screw the metal conductive rod body 2 into the vertical limiting cylinder 3, causing the metal conductive rod body 2 to gradually sink below the ground. When the rotating bar 10 completely passes through the first limiting ring 101, the rotating bar 10 is rotated away from the strip groove 8 by means of the torsion action of the rotating shaft 9, thus expanding outward and improving the stability of the metal conductive rod body 2. Compared with the prior art, this invention can prevent the metal conductive rod body from sinking downward when installing the spark extinguishing device, thereby improving the stability of the metal conductive rod body.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
