[0024] The present scheme proposes a box-type substation sound insulation protection structure. In actual use, when the sealing rubber 2 becomes thinner due to deterioration of elasticity or wear, the spring 5 in a compressed state extends out of the spring groove 4 at one end close to the inner lining plate 3, and pushes the inner lining plate 3 toward the door frame of the box-type substation under the action of its own elasticity. As the inner lining plate 3 moves, the sealing rubber 2 also moves in the direction of extending out of the sealing rubber installation groove 11, so that the sealing rubber 2 can still be pressed against the door frame under the elasticity of the spring 5, thereby preventing the sound insulation protection effect from deteriorating due to the thinning of the sealing rubber 2.

[0025] Embodiment 2

[0026] On the basis of Example 1, in order to prevent the inner lining plate 3 and the sealing rubber 2 from being ejected out of the sealing rubber mounting groove 11 after the door is opened, a plug rod 7 is fixed on the surface of the inner lining plate 3 away from the sealing rubber 2, and the plug rod 7 has a round rod structure. The other end of the plug rod 7 is movably inserted in the plug hole 6, which has a round hole structure. One end of the plug hole 6 is opened on the inner wall of the groove body of the sealing rubber mounting groove 11, and the other end of the plug hole 6 is opened on the surface of the end of the door panel 1 away from the inner lining plate 3. The end of the plug rod 7 away from the inner lining plate 3 extends out of the surface of the door panel 1 from the plug hole 6, and a card slot 8 is opened on the rod body of the part of the plug rod 7 extending out of the surface of the door panel 1, and a card mounting plate 9 is arranged at the position where the plug hole 6 is opened on the surface of the door panel 1, and a card 10 is movably inserted in the card mounting plate 9, and the card 10 has a "U"-shaped plate structure, and the two side panels of the card 10 are movably inserted in the card slot 8.

[0027] After the door is opened, the inner lining plate 3 moves away from the card mounting plate 9 under the elastic force of the spring 5, which causes the plug-in rod 7 to move along with the inner lining plate 3. However, after the plug-in rod 7 moves a short distance, the side plate of the card 10 will be stuck on the inner wall of the card slot 8, making it impossible for the plug-in rod 7 to escape from the plug-in hole 6, and also preventing the inner lining plate 3 and the sealing rubber 2 from being completely ejected from the sealing rubber mounting slot 11.

[0028] Embodiment 3

[0029] On the basis of Example 2, in order to replace the sealing rubber 2, a plug-in rod 7 is fixed on the surface of the inner lining plate 3 away from the sealing rubber 2, and the plug-in rod 7 is a round rod structure. The other end of the plug-in rod 7 is movably inserted in the plug-in hole 6, and the plug-in hole 6 is a round hole structure. One end of the plug-in hole 6 is opened on the inner wall of the sealing rubber mounting groove 11, and the other end of the plug-in hole 6 is opened on the surface of the end of the door panel 1 away from the inner lining plate 3. The end of the plug-in rod 7 away from the inner lining plate 3 extends out of the surface of the door panel 1 from the plug-in hole 6, and a card slot 8 is opened on the rod body of the part of the plug-in rod 7 extending out of the surface of the door panel 1, and a card mounting plate 9 is arranged at the position where the plug-in hole 6 is opened on the surface of the door panel 1, and a card 10 is movably inserted in the card mounting plate 9, and the card 10 is a "U"-shaped plate structure, and the two side panels of the card 10 are movably inserted in the card slot 8.

[0030] After the sealing rubber 2 is worn out, the card 10 is pulled out from the card mounting plate 9, and the card 10 is also pushed out from the card slot 8. At this time, the door panel 1 is opened again, and the plug-in rod 7 is pushed out from the plug-in hole 6, so that the sealing rubber 2 and the inner lining plate 3 can be pushed out from the sealing rubber mounting groove 11, and then the inner lining plate 3 with the new sealing rubber 2 is installed back into the sealing rubber mounting groove 11, and the plug-in rod 7 on the new inner lining plate 3 is reinserted into the plug-in hole 6, and finally the card 10 is inserted back into the card mounting plate 9, and the card 10 is also reinserted into the card slot 8, and the limit of the plug-in rod 7 is restored, and the replacement of the sealing rubber 2 can be completed very conveniently.

[0031] In actual use, when the sealing rubber 2 becomes thinner due to poor elasticity or wear, the spring 5 in a compressed state extends out of the spring groove 4 at one end close to the inner lining plate 3, and pushes the inner lining plate 3 toward the door frame of the box-type substation under the action of its own elasticity. As the inner lining plate 3 moves, the sealing rubber 2 also moves in the direction of extending out of the sealing rubber mounting groove 11, so that the sealing rubber 2 can still be pressed against the door frame under the elasticity of the spring 5, preventing the sound insulation protection effect from becoming poor due to the thinning of the sealing rubber 2; after opening the door, the inner lining plate 3 moves in the direction away from the card mounting plate 9 under the elastic force of the spring 5, which makes the plug rod 7 move with the inner lining plate 3, but when the plug rod 7 moves a short distance, the side plate of the card 10 will be stuck in the inner of the card slot 8. After the sealing rubber 2 is worn out, the card 10 is pulled out from the card mounting plate 9, and the card 10 is also pushed out from the card slot 8. At this time, the door panel 1 is opened again, and the connecting rod 7 is pushed out from the connecting hole 6, so that the sealing rubber 2 and the inner lining plate 3 are pushed out from the sealing rubber mounting groove 11. Then, the inner lining plate 3 equipped with a new sealing rubber 2 is installed back into the sealing rubber mounting groove 11, and the connecting rod 7 on the new inner lining plate 3 is reinserted into the connecting hole 6. Finally, the card 10 is inserted back into the card mounting plate 9, and the card 10 is also reinserted into the card slot 8. The limit of the connecting rod 7 is restored, and the replacement of the sealing rubber 2 can be completed very conveniently.
