[0022] As Figures 1 - 5 shown, the present utility model provides a technical solution: a loading and unloading device for hazardous chemicals in a storage area, including a tank connecting pipe 1, a hazardous chemical storage tank 4, and a loading and unloading pipe 5. A control part 3 for improving the loading and unloading efficiency is arranged on the right side of the tank connecting pipe 1.

[0023] One end of the main pipeline 31 close to the tank connection pipe 1 is fixedly connected to the tank connection pipe 1 by bolts. The other end of the main pipeline 31 away from the tank connection pipe 1 penetrates and is fixedly connected with a pump body 32. The surface of the pump body 32 penetrates and is fixedly connected with a loading pipeline 33. When loading dangerous chemicals, the loading and unloading pipeline 5 at the transportation location is docked with the loading pipeline 33, and then the first valve 37, the second valve 38, and the third valve 39 are opened and the pump body 32 is started, so that the pump body 32 can actively extract the dangerous chemicals in the dangerous chemical storage tank 4 and load them through the loading pipeline 33, improving the efficiency during loading. A secondary pipeline 34 penetrates and is fixedly connected between the main pipeline 31 and the loading pipeline 33. The surface of the main pipeline 31 penetrates and is fixedly connected with an unloading pipeline 35. The unloading pipeline 35 penetrates and is fixedly connected with a fourth valve 36. The surface of the main pipeline 31 penetrates and is fixedly connected with a first valve 37. The secondary pipeline 34 penetrates and is fixedly connected with a second valve 38. The loading pipeline 33 penetrates and is fixedly connected with a third valve 39. During unloading, the loading and unloading pipeline 5 is aligned with the unloading pipeline 35 and connected. The second valve 38 and the third valve 39 are closed, and the fourth valve 36 is opened, so that the dangerous chemicals on the transport vehicle can be loaded into the tank through the unloading pipeline 35. By using specific pipelines for loading and unloading, the unloading pipeline 35 can be connected to the transport vehicle during loading, and directly unloaded and loaded into the tank after loading is completed. Connection parts 2 are provided at both the end of the loading pipeline 33 away from the pump body 32 and the end of the unloading pipeline 35 away from the main pipeline 31 to facilitate the docking of the loading and unloading pipeline 5.

A first spring 22 is fixedly connected to the surface of the telescopic pipeline 21. One end of the first spring 22 away from the telescopic pipeline 21 is fixedly connected to the inner wall of the loading pipeline 33. When the loading and unloading pipeline 5 is connected to the loading pipeline 33 or the unloading pipeline 35, taking the loading pipeline 33 as an example, the loading and unloading pipeline 5 at the transportation location is aligned with the loading pipeline 33 and pushed in, so that the flange on the loading and unloading pipeline 5 abuts against the telescopic pipeline 21, causing the telescopic pipeline 21 to contract into the loading pipeline 33. An installation groove 219 is formed on one side of the telescopic pipeline 21 close to the loading and unloading pipeline 5. A fixing plate 23 is fixedly connected through the loading pipeline 33. A sliding groove 24 is formed on the surface of the fixing plate 23. An I-shaped slider 25 is slidably connected through the inner side of the sliding groove 24. The telescopic pipeline 21 contracts into the loading pipeline 33. At this time, the flanges of both the loading and unloading pipeline 5 and the telescopic pipeline 21 are located between the first installation piece 26 and the second installation piece 211. At this time, the rotating ring 213 can be toggled, so that the arc-shaped groove 214 formed on the surface of the rotating ring 213 abuts against the sliding rod 28, thereby forcing the sliding rod 28 to drive the I-shaped slider 25 to slide in the sliding groove 24. An installation piece 26 is fixedly connected to the surface of the I-shaped slider 25. A connecting column 27 is fixedly connected to the surface of the installation piece 26. A sliding rod 28 is fixedly connected to the surface of the I-shaped slider 25 away from the installation piece 26.
[0025] A pull rod 29 passes through and is slidably connected to the inner side of the connecting column 27.

An arc - shaped groove 214 is formed on the surface of the rotating ring 213, and a reset plate 215 is fixedly connected to the surface of the rotating ring 213. A fixing piece 216 is fixedly connected to the surface of the loading vehicle pipeline 33. A circular ring 217 passes through and is fixedly connected to the surface of the fixing piece 216. The circular ring 217 passes through the reset plate 215 and is slidably connected, and an arc - shaped spring 218 is fixedly connected between the reset plate 215 and the fixing piece 216.
[0026] Based on the above - mentioned embodiment, when loading dangerous chemicals, the loading and unloading vehicle pipeline 5 at the transportation location is docked with the loading vehicle pipeline 33. Then, the first valve 37, the second valve 38, and the third valve 39 are opened and the pump body 32 is started, so that the pump body 32 can actively extract the dangerous chemicals in the dangerous chemical storage tank 4 and load them through the loading vehicle pipeline 33, improving the efficiency during loading. When unloading, the loading and unloading vehicle pipeline 5 is aligned with the unloading pipeline 35 and connected. The second valve 38 and the third valve 39 are closed, and the fourth valve 36 is opened, so that the dangerous chemicals on the transport vehicle can be loaded into the tank through the unloading pipeline 35. By using specific pipelines for loading and unloading, the unloading pipeline 35 can be connected to the transport vehicle during loading, and directly unload and load the tank after loading is completed. It is possible to avoid removing the loading and unloading vehicle pipeline 5 for loading after loading is completed, and then connecting the loading and unloading vehicle pipeline 5 of the unloading vehicle for unloading, which can achieve dedicated pipeline use and improve the loading and unloading efficiency.
[0027] When connecting the loading and unloading pipeline 5 with the loading pipeline 33 or the unloading pipeline 35, taking the loading pipeline 33 as an example, align the loading and unloading pipeline 5 on the transportation site with the loading pipeline 33 and push it in, so that the flange on the loading and unloading pipeline 5 abuts against the telescopic pipeline 21, causing the telescopic pipeline 21 to contract into the loading pipeline 33. At this time, the flanges of the loading and unloading pipeline 5 and the telescopic pipeline 21 are both located between the first mounting plate 26 and the second mounting plate 211. At this time, the rotating ring 213 can be toggled, so that the arc-shaped groove 214 formed on the surface of the rotating ring 213 abuts against the sliding rod 28, thereby forcing the sliding rod 28 to drive the I-shaped slider 25 to slide in the chute 24, and the I-shaped slider 25 will drive the first mounting plate 26 and the second mounting plate 211 to clamp the flanges of the loading and unloading pipeline 5 and the telescopic pipeline 21. Subsequently, the telescopic pipeline 21 and the loading and unloading pipeline 5 are tightened and fixed by passing bolts through the first mounting plate 26 and the second mounting plate 211. Through the circumferentially arranged first mounting plate 26 and the second mounting plate 211 and their ability to freely contract and expand, the connection of loading and unloading pipelines 5 of different sizes can be achieved, which is convenient and fast.
[0028] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
