Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , an embodiment provided by the present utility model: A safety cover for chemical pipeline connection, including a transportation pipeline 1, a first protective cover 2, and a second protective cover 3. One end of the transportation pipeline 1 is fixedly connected with a flange joint 4. Two transportation pipelines 1 are connected through the flange joint 4. A medium detection sensor 6 is fixedly installed on one side of the first protective cover 2. The sensing end of the medium detection sensor 6 is located inside the first protective cover 2. An acoustic-optic alarm 5 is fixedly installed on one side of the first protective cover 2 close to the medium detection sensor 6. A controller 7 is fixedly installed on one side of the first protective cover 2 close to the medium detection sensor 6. Two first fixing ears 8 are symmetrically and fixedly connected to the bottom ends on both sides of the first protective cover 2 respectively. Two first arc-shaped sealing gaskets 9 are symmetrically and movably inserted into the inner side of the bottom end of the first protective cover 2. Connection pieces 10 are fixedly connected to the two ends of the first arc-shaped sealing gasket 9 away from the first protective cover 2 respectively.

[0022] The controller 7 is respectively connected in a wired electrical manner to the acoustic-optic alarm 5, the medium detection sensor 6, and the control room terminal. It selects and detects the sensor corresponding to the medium transmitted by the transportation pipeline 1. The medium detection sensor 6 monitors the medium content inside the first protective cover 2 and the second protective cover 3 in real time. When there is a medium leak at the joint of the transportation pipeline 1, the medium detection sensor 6 detects an increase in the medium content. When the medium content reaches a predetermined threshold, the controller 7 activates the alarm to control the acoustic-optic alarm 5 to start an acoustic-optic alarm and transmits the leak information to the control room terminal to notify the staff to perform maintenance in a timely manner, thereby preventing the leak in the first time.

[0023] Two second fixing ears 11 are symmetrically and fixedly connected to the two top ends on both sides of the second protective cover 3 respectively. Two connecting sealing gaskets 12 are symmetrically and movably inserted into the top end of the second protective cover 3. Sealing insertion grooves 13 are formed at the top and bottom ends of the connecting sealing gasket 12. Two second arc-shaped sealing gaskets 15 are symmetrically and fixedly connected between the two connecting sealing gaskets 12. A connecting notch 14 is provided at one end of the connecting sealing gasket 12 close to the second arc-shaped sealing gasket 15.

[0024] A groove is formed on one side of the first arc-shaped sealing gasket 9 close to the first protective cover 2. The inner side of the top end of the first protective cover 2 is movably inserted into the groove of the first arc-shaped sealing gasket 9. A groove is formed on one side of the second arc-shaped sealing gasket 15 close to the second protective cover 3. The inner side of the top end of the second protective cover 3 is movably inserted into the groove of the second arc-shaped sealing gasket 15. The bottom end of the first protective cover 2 is movably inserted into the inner side of the sealing insertion groove 13 located at the top end of the connecting sealing gasket 12. The top end of the second protective cover 3 is movably inserted into the inner side of the sealing insertion groove 13 located at the bottom end of the connecting sealing gasket 12. The connecting sealing gasket 12 seals the connection between the first protective cover 2 and the second protective cover 3 to prevent the spread of leakage and cause safety accidents. Both sides of the connecting piece 10 are respectively close to the transportation pipeline 1 and the connecting notch 14. The connection of the connecting piece 10 can increase the sealing performance of the connection. Moreover, the first protective cover 2 and the second protective cover 3 are connected and fixed by bolts passing through the first fixing ear 8 and the second fixing ear 11. The sides of the first arc-shaped sealing gasket 9 away from the first protective cover 2 and the sides of the second arc-shaped sealing gasket 15 away from the second protective cover 3 are respectively close to the outer side of the transportation pipeline 1, and the flange joint 4 is located inside the first protective cover 2 and the second protective cover 3.

[0025] Working principle: During use, first select and detect the sensor corresponding to the medium transported by the transport pipeline 1 according to the medium, and set the leakage threshold through the controller 7. Then, install the first protective cover 2 and the second protective cover 3 at the joint of the transport pipeline 1, and adjust the positions of the first protective cover 2 and the second protective cover 3 according to the density of the medium transported by the transport pipeline 1. When the medium density is greater than the air density, the first protective cover 2 is located below the second protective cover 3, so that the medium detection sensor 6 is located directly below the transport pipeline 1. When the medium density is less than the air density, the first protective cover 2 is located above the second protective cover 3, so that the medium detection sensor 6 is located directly above the transport pipeline 1. Insert the connecting gasket 12 and the second arc-shaped gasket 15 at one end of the second protective cover 3 close to the first protective cover 2, then insert the two first arc-shaped gaskets 9 at one end of the first protective cover 2 close to the second protective cover 3 respectively, and insert the first protective cover 2 inside the sealing insertion groove 13, and fix the first protective cover 2 and the second protective cover 3 by bolts passing through the first fixing ear 8 and the second fixing ear 11 to achieve the sealing of the joint of the transport pipeline 1. The medium detection sensor 6 monitors the medium content inside the first protective cover 2 and the second protective cover 3 in real time and transmits it to the controller 7 in real time. The controller 7 transmits the detection data to the control room terminal. When there is a medium leakage at the joint of the transport pipeline 1, the medium content inside the first protective cover 2 and the second protective cover 3 increases. At this time, the medium detection sensor 6 detects the increase in the medium content. When the medium content reaches the predetermined threshold, the controller 7 activates the alarm to control the sound and light alarm 5 to start the sound and light alarm, and transmits the leakage information to the control room terminal to notify the staff to maintain in time, so as to prevent the leakage in the first time. At the same time, the first protective cover 2 and the second protective cover 3 seal the joint of the transport pipeline 1 through the first arc-shaped gasket 9, the connecting gasket 12 and the second arc-shaped gasket 15 to prevent the leakage from spreading.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
