[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an explosion-proof safety protection device for oil well sites. (Refer to...) Figure 1 and Figure 5 An explosion-proof safety protection device for oil well sites includes an oil drum body 1, a sealing mechanism 2 is provided on the top of the oil drum body 1, and a fixing mechanism 3 is provided on the surface of the sealing mechanism 2.

[0026] The sealing mechanism 2 includes an oil inlet pipe 201. The bottom of the oil inlet pipe 201 is fixedly connected to the inner cavity of the oil drum body 1. The inner cavity of the oil inlet pipe 201 is movably connected to a sealing gasket 203. The inner cavity of the oil inlet pipe 201 is movably connected to an oil drum cover 206. An arc-shaped groove 209 is opened on the surface of the oil drum cover 206. The inner cavity of the oil inlet pipe 201 is fixedly connected to a support shaft 204. There are two support shafts 204. The surface of each support shaft 204 is movably connected to a pressing rod 205. The surface of the pressing rod 205 is movably connected to the inner cavity of the arc-shaped groove 209.

[0027] Reference Figure 2 and Figure 3A limiting groove 202 is provided in the inner cavity of the oil inlet pipe 201. The inner cavity of the limiting groove 202 is engaged with the surface of the sealing gasket 203. The position of the sealing gasket 203 is limited by the limiting groove 202. When the sealing gasket 203 is pressed by the oil drum cover 206, the sealing gasket 203 will deform and seal the connection between the oil drum cover 206 and the oil inlet pipe 201.

[0028] Reference Figure 4 The surface of the oil drum lid 206 is provided with a sliding groove 208. There are two sliding grooves 208. The inner cavity of each sliding groove 208 is movably connected to the surface of a pressing rod 205. The sliding groove 208 provides a guide for the pressing rod 205 to slide into the arc groove 209 in the oil drum lid 206, and avoids the pressing rod 205 from being stuck when it comes into contact with the surface of the oil drum lid 206, which would make it difficult to slide into the inner cavity of the arc groove 209 in the oil drum lid 206.

[0029] Reference Figure 3 The fixing mechanism 3 includes a movable ring 301, which is sleeved on the outside of the oil inlet pipe 201. A mounting bracket 302 is fixedly connected to the surface of the movable ring 301. There are two mounting brackets 302. A snap-fit ​​rod 303 is movably connected to the inner cavity of the mounting bracket 302. One end of the snap-fit ​​rod 303 passes through the movable ring 301 and is movably connected to the inner cavity of the oil inlet pipe 201. By setting the movable ring 301, the mounting bracket 302 and the snap-fit ​​rod 303 to work together, when the movable ring 301 is pulled so that its inner cavity contacts the surface of the pressing rod 205, and then the snap-fit ​​rod 303 is snapped into the inner cavity of the oil inlet pipe 201, the position of the pressing rod 205 is limited, so as to prevent the pressing rod 205 from rotating under the influence of external force.

[0030] Reference Figure 3 A retaining ring 308 is fixedly connected to the surface of the snap-fit ​​rod 303, and a spring 305 is fixedly connected to the surface of the retaining ring 308. One end of the spring 305 is fixedly connected to the inner cavity of the mounting bracket 302. By setting the spring 305 and the retaining ring 308 to work together, due to the elasticity of the spring 305, the retaining ring 308 is always driven to have an inward force, so that the snap-fit ​​rod 303 is always in contact with the surface of the guide block 304 when it slides to the surface of the guide block 304, and when the snap-fit ​​rod 303 slides out of the surface of the guide block 304, it snaps into the inner cavity of the snap-fit ​​hole 207 in the oil inlet pipe 201.

[0031] Reference Figure 5The surface of the oil inlet pipe 201 is provided with guide grooves 307. There are two guide grooves 307. The inner cavity of each guide groove 307 is movably connected with a sliding block 306. The surface of the sliding block 306 is fixedly connected to the inner side of the movable ring 301. Through the setting of the sliding block 306 and the guide groove 307, the movable ring 301 slides on the outside of the oil inlet pipe 201, which limits and guides the movement of the movable ring 301. This prevents the movable ring 301 from rotating and causing the locking rod 303 indirectly driven by the movable ring 301 to fail to lock smoothly into the inner cavity of the locking hole 207.

[0032] Reference Figure 3 and Figure 4 The surface of the oil inlet pipe 201 is provided with two snap-fit ​​holes 207. The inner cavity of each snap-fit ​​hole 207 is movably connected to the surface of a snap-fit ​​rod 303. The snap-fit ​​holes 207 provide a position for the snap-fit ​​rod 303 to snap into the inner cavity of the oil inlet pipe 201. When one end of the snap-fit ​​rod 303 snaps into the inner cavity of the snap-fit ​​hole 207, the position of the movable ring 301 is fixed. The movable ring 301 limits and fixes the position of the pressing rod 205.

[0033] Reference Figure 3 Two guide blocks 304 are fixedly connected to the surface of the oil inlet pipe 201. The guide blocks 304 are inclined and each guide block 304 is movably connected to the surface of a locking rod 303. The guide blocks 304 limit and guide the locking rod 303. When the surface of the locking rod 303 contacts the surface of the guide block 304, the elasticity of the spring 305 indirectly drives the locking rod 303 to move inward. The guide block 304 is inclined, so the locking rod 303 is not able to disengage from the guide block 304 without external force, so the movable ring 301 will not move upward. When it is necessary to limit and fix the pressing rod 205, the movable ring 301 is pulled to indirectly drive the locking rod 303 to move upward on the inclined surface of the guide block 304. When the locking rod 303 disengages from the highest point of the inclined surface of the guide block 304, it can be locked into the inner cavity of the locking hole 207 in the oil inlet pipe 201.

[0034] Working principle: After crude oil is extracted from the oil well site, it is injected into the inner cavity of the oil drum body 1 through the inlet pipe 201. To prevent the crude oil from leaking flammable and explosive gases to the outside, the sliding groove 208 of the oil drum cover 206 is first aligned with the position of the pressing rod 205 and pushed into the inner cavity of the inlet pipe 201. Then, the pressing rod 205 is rotated until it fits against the inner cavity of the arc-shaped groove 209. Next, the oil drum cover 206 is rotated, at which point the arc-shaped groove 209 slides on the surface of the pressing rod 205. Then, it moves downwards... Rotating the pressing rod 205, since the pressing rod 205 is located eccentrically around the rotating support shaft 204, when the pressing rod 205 rotates downwards, its thick surface contacts the inner cavity of the arc-shaped groove 209 in the oil drum cover 206, thereby generating a downward force on the oil drum cover 206. This causes the oil drum cover 206 to press against the sealing gasket 203. Since the sealing gasket 203 is made of rubber, it will deform when pressed, thereby sealing the connection between the pressing rod 205 and the oil inlet pipe 201. To prevent the leakage of flammable and explosive gases from inside the oil drum body 1, the movable ring 301 is then lifted upwards. The movable ring 301 moves the mounting bracket 302, which in turn moves the locking rod 303. When one end of the locking rod 303 contacts the inclined surface of the guide block 304, an outward force is generated on the locking rod 303, thereby moving the fixed ring 308. The fixed ring 308 then causes the spring 305 to deform. When the locking rod 303 slides out at the highest point of the inclined surface of the guide block 304... At this time, due to the elastic force of the spring 305, the fixed ring 308 moves inward, and the fixed ring 308 drives the locking rod 303 to slide inward and lock into the inner cavity of the locking hole 207 in the oil inlet pipe 201. At the same time, the movable ring 301 will drive the sliding block 306 to slide in the inner cavity of the guide groove 307 in the oil inlet pipe 201. At this time, the inner cavity of the movable ring 301 contacts the surface of the pressing rod 205, preventing the pressing rod 205 from being rotated by external force and losing the downward pressing force on the oil drum cover 206.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
