Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, and in particular to a leakage-proof storage tank. Background Art

[0002] A storage tank is a storage device used to store liquid and other refined chemicals.

[0003] There are two main factors that cause leakage in storage tanks. One is the quality problem of the storage tank itself. If it ruptures, the stored liquid raw materials will flow out from the ruptured part, causing leakage. The other is human factors. Non-staff dismantles the discharge end of the loose storage tank, which affects the sealing state of the discharge end and causes leakage. Leakage caused by human factors is an emergency and cannot be detected through daily inspections and observations. When a leakage occurs due to human factors, the responsible personnel cannot be notified in time, resulting in long-term leakage and pollution of the surrounding environment. The discharge end of the current storage tank mostly uses flange sealing to achieve fixed sealing, but its fixing method is simple and can be easily disassembled by humans, leading to leakage problems.

[0041] The working principle of this embodiment:

[0042] When storing liquid raw materials, the liquid raw materials are added into the storage chamber 108 through the feeding connecting hole 109, and then the flange 103 and the flange sealing plate 104 are locked and connected by the locking bolts 105, so that the flange sealing plate 104 can realize installation and sealing of the opening end of the feeding connecting hole 109; when it is necessary to discharge the liquid raw materials in the storage chamber 108, the bolt locking member 1013 is disassembled by rotating along the threaded blind hole 205 with an inner hexagonal wrench, so that the stud end of the bolt locking member 1013 is separated from the threaded blind hole 205, so that there is no threaded cooperation between the bolt locking member 1013 and the threaded blind hole 205, and the matching sealing block 2 can be separated from the matching plate 107, so that the sealing block 203 sealed and inserted in the sealing embedding groove 1011 is separated from the sealing embedding groove 1011, and the opening end of the discharge connecting hole 1010 is exposed, so as to facilitate the discharge operation of the liquid raw materials in the storage chamber 108;

[0043] In order to avoid leakage caused by non-staff disassembling or loosening the matching sealing block 2, the present invention adopts the threaded connection between the bolt locking member 1013 and the threaded blind hole 205 as a concealed fixed installation, and sets the simulation block 201 and the simulation column 202 with the appearance structure similar to the stud and nut as the fixed installation simulating the traditional stud nut installation method. Through this design, non-staff who are not familiar with the specific structure of the present invention will identify the simulation block 201 and the simulation column 202 as the locking fixtures for fixing the matching sealing block 2. When they intend to disassemble or loosen the matching sealing block 2, they will inevitably twist the simulation block 201 with tools.

[0044] Furthermore, the present invention closely adheres to the rotating block 209 by the bolt pressing member 206 in the threaded locking state along the threaded through hole 2017, so as to achieve limited fixation of the rotating block 209. Therefore, without the cooperation of tools, the simulation block 201 cannot be twisted by twisting the fingers alone. Therefore, in this way, the intention of twisting the simulation block 201 can be identified (if it is not intended to disassemble or loosen the matching sealing block 2, it only touches the simulation block 201 with the fingers, and the rotating block 209 is closely adhered to by the bolt pressing member 206, and it is impossible to twist the simulation block 201. If it is intended to disassemble or loosen the matching sealing block 2, it twists the simulation block 201 with a tool, and its subjective intention can be determined);

[0045] When a non-staff member intends to disassemble or loosen the mating sealing block 2, and twists the simulation block 201 with a tool, the simulation block 201 will be twisted under the twisting force of the mating tool, thereby synchronously driving the rotating block 209 to rotate along the rotating cavity 2018. When the rotating block 209 rotates along the rotating cavity 2018, the non-connected parts of the corresponding metal sensing part 2010 on the outer circumferential surface of the rotating block 209 will be staggered with the position of the sensing installation groove 216. At this time, the metal sensing part 2010 is within the sensing range of the sensing component 2014. When the sensing component 2014 senses the metal sensing part 2010, The sensing component 2014 gives a feedback signal to the microcontroller 2022, and the microcontroller 2022 controls the buzzer 2013 to start sounding. The buzzer warning is used to warn and deter current non-staff members to prevent them from continuing the disassembly operation. At the same time, the microcontroller 2022 controls the buzzer 2013 to start sounding, and also controls the 5G module 2020 to wirelessly transmit a message to the mobile device 21 of the mobile phone of the person in charge of the tank body 1, so that the person in charge of the tank body 1 can be informed at the first time and go there in time to check the installation status of the matching sealing block 2 to avoid leakage.
