[0018] The following will further describe the present invention in conjunction with the drawings in the specification.

[0019] The present utility model provides the following technical solutions:

[0020] As shown in the attached Figures 1-3 figure, the present utility model discloses a highly sealed storage tank, which includes a tank body 1 and a manhole cover 2. A cover connection end 3 is provided on the tank body 1, and the manhole cover 2 is detachably arranged on the cover connection end 3. A sealing component is arranged between the manhole cover 2 and the cover connection end 3. The sealing component includes a cover sealing member 4 and a tank body sealing member 5. A cover sealing groove 6 is recessed on the edge of one side end face of the manhole cover 2 close to the cover connection end 3. The cover sealing member 4 is arranged in the cover sealing groove 6 in an annular structure. A connection gap 7 is formed between the cover sealing groove 6 and the end face of the cover sealing member 4 away from the center of the manhole cover 2. The tank body sealing member 5 is arranged on the cover connection end 3, and one end of the tank body sealing member 5 extends into the connection gap 7 and is hermetically connected to the groove wall of the cover sealing groove 6 and the cover sealing member 4 respectively. Specifically, in this design, by arranging a sealing component composed of a cover sealing member 4 and a tank body sealing member 5 between the manhole cover 2 and the cover connection end 3 of the tank body 1, a double sealing effect is achieved, ensuring the high sealing performance inside the storage tank. One end of the tank body sealing member 5 extends into the connection gap 7, which can increase the sealing contact area, thereby improving the sealing effect.

[0021] Furthermore, the upper part of the cover sealing member 4 is fixedly adhered to the cover sealing groove 6. A tank body sealing ring groove 8 is opened on the cover connection end 3. The tank body sealing ring groove 8 has an inner sealing part 9 and an outer sealing part 10. The lower part of the cover sealing member 4 extends into the inner sealing part 9 and is hermetically connected to the cover connection end 3. The tank body sealing member 5 is arranged in the outer sealing part 10 in an annular structure. Specifically, in this embodiment, by opening a tank body sealing ring groove 8 on the cover connection end 3 and arranging the tank body sealing member 5 in the outer sealing part 10, the sealing effect is further enhanced. The design of the inner and outer sealing parts 10 of the tank body sealing ring groove 8 enables the tank body sealing member 5 to form a double seal with the cover connection end 3, thereby ensuring the high sealing performance inside the storage tank.

[0022] Furthermore, a plurality of annular grooves 11 are equidistantly opened at the lower part of the cover sealing member 4. Annular ends 12 are correspondingly arranged on the groove wall of the inner sealing part 9 for the annular grooves 11. The annular ends 12 extend into the corresponding annular grooves 11 and are hermetically connected to the cover sealing member 4. Specifically, in this embodiment, by equidistantly opening a plurality of annular grooves 11 at the lower part of the cover sealing member 4 and correspondingly arranging annular ends 12 on the groove wall of the inner sealing part 9, the annular ends 12 can extend into the corresponding annular grooves 11 and closely cooperate with the cover sealing member 4, thereby further improving the sealing performance of the sealing component. This design not only increases the sealing contact area, but also through the mutual cooperation of the annular grooves 11 and the annular ends 12, enables the sealing component to still maintain a good sealing effect when the pressure changes.

[0023] Furthermore, the cross-section of the tank body seal 5 is arranged in an L-shaped structure. The tank body seal 5 has a tank body sealing portion 13 and a cover body sealing portion 14. The tank body sealing portion 13 is arranged in the outer sealing portion 10 of the tank body sealing ring groove 8 and is in sealing contact with the cover body connection end 3. The cover body sealing portion 14 protrudes from the outer side of the top end of the tank body sealing portion 13, and the cover body sealing portion 14 extends into the cover body sealing groove 6 and is in sealing contact with the groove wall of the cover body sealing groove 6. Specifically, in this embodiment, by designing the cross-section of the tank body seal 5 to be in an L-shaped structure, the tank body sealing portion 13 can form good sealing contact with the cover body connection end 3. At the same time, the protruding part of the cover body sealing portion 14 extends into the cover body sealing groove 6 and closely cooperates with the groove wall of the cover body sealing groove 6. This design not only ensures the sealing effect between the tank body sealing portion 13 and the cover body connection end 3, but also the protruding design of the cover body sealing portion 14 increases the contact area with the cover body sealing groove 6, further improving the overall sealing performance of the sealing assembly. And in this design, the part of the tank body seal 5 extending into the connection gap 7 is the cover body sealing portion 14 of the tank body seal 5. The width of the cover body sealing portion 14 is greater than the width of the connection gap 7. And since the cover body seal 4 is made of rubber and the tank body seal 5 is made of ceramic, the cover body sealing portion 14 extrudes the cover body seal 4 and deforms it after extending into the connection gap 7, thereby achieving a more tight sealing effect.

[0024] Furthermore, the manhole cover 2 is rotatably connected to the cover body connection end 3. The manhole cover 2 has a hole cover rotating portion 15, and the cover body connection end 3 has a rotating connection portion 16. Corresponding rotating holes 17 are provided on both the hole cover rotating portion 15 and the rotating connection portion 16, and the rotating holes are rotatably connected through a rotating shaft 18. Specifically, in this embodiment, by providing a rotating connection structure between the manhole cover 2 and the cover body connection end 3, the manhole cover 2 can be conveniently opened and closed, improving the operation convenience. The rotating holes 17 provided on the hole cover rotating portion 15 and the rotating connection portion 16, in cooperation with the rotating shaft 18, ensure the stability and reliability of the rotating connection. In addition, the setting of the rotating shaft 18 enables the manhole cover 2 to remain stable during the opening and closing process, avoiding damage to the sealing assembly caused by improper operation, thereby further ensuring the high sealing performance inside the storage tank.

[0025] Furthermore, a locking screw 19 is also provided between the manhole cover 2 and the cover body connection end 3. Corresponding screw holes 20 are provided on the manhole cover 2 and the cover body connection end 3. The locking screw 19 passes through the screw hole 20 on the manhole cover 2 and extends into the screw hole 20 on the cover body connection end 3 to lock and connect the manhole cover 2 and the cover body connection end 3. Specifically, in this embodiment, by providing the locking screw 19, the tight connection between the manhole cover 2 and the cover body connection end 3 can be ensured, thereby further enhancing the sealing effect. The locking screw 19 passes through the screw hole 20 on the manhole cover 2 and extends into the screw hole 20 on the cover body connection end 3. By tightening the locking screw 19, a stable locking force is formed between the manhole cover 2 and the cover body connection end 3 to prevent the loosening of the sealing assembly caused by vibration or pressure change. In addition, the setting of the locking screw 19 also facilitates the disassembly and maintenance of the manhole cover 2 when needed, improving the flexibility and safety of the storage tank in use.

[0026] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
