Description

Technical Field

[0001] This utility model relates to the field of gas storage tank technology, and specifically to a segmented tank body connection structure for a gas storage tank. Background Technology

[0002] As a core device for storing gases and stabilizing system pressure, gas storage tanks have adopted a segmented tank design to address the inconvenience of overall transportation. This design, by dividing the tank into multiple units, significantly reduces transportation difficulties and meets the logistical needs of practical applications. Currently, the assembly process of segmented tanks generally adopts the connection method of flanges, threaded rods, nuts and sealing rings. Although it can achieve preliminary sealing assembly, it has obvious functional defects: after assembly, there is a lack of long-term effective monitoring methods to check whether the connection parts are loose or leaking, making it difficult to grasp the sealing status in real time, which brings safety hazards and maintenance blind spots to subsequent use. To address the aforementioned issues, this application proposes a segmented tank connection structure for gas storage tanks. Summary of the Invention

[0003] This utility model addresses the technical problems existing in the prior art by providing a segmented tank connection structure for gas storage tanks.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a segmented tank body connection structure for a gas storage tank, including an upper tank, a middle tank, and a lower tank, wherein the upper tank, the middle tank, and the lower tank are detachably assembled and connected. Both the upper tank and the middle tank are welded with upper flanges; Both the middle section tank and the lower section tank are welded with lower flanges. Two sets of monitoring structures are installed on each of the upper tank, middle tank, and lower tank; Each monitoring structure includes a mounting shell and a mounting block. An alarm is mounted on the mounting shell, a power supply is installed inside the mounting shell, a contact switch is installed at the bottom of the mounting shell, a threaded rod is threaded through the mounting block, and a touch plate is installed at the top of the threaded rod. The power supply, alarm, and contact switch are electrically connected. The mounting housing is equipped with an anti-accidental touch component.

[0005] A rotating block is installed at the bottom end of the threaded rod. By setting the rotating block, it is possible to rotate the threaded rod.

[0006] The mounting housing is fitted with the top of the upper flange, and the mounting block is fitted with the bottom of the lower flange to fix the positions of the mounting housing and the mounting block.

[0007] The anti-accidental activation component includes a protective cover that is slidably connected to the mounting housing. By setting the protective cover, the rotating block, threaded rod, touch plate, and contact switch are covered to minimize accidental contact that could cause the alarm to mis-alarm.

[0008] The mounting shell has a sliding groove, and the inner side of the protective cover is equipped with a sliding strip. The sliding strip is slidably connected to the mounting shell through the sliding groove. By setting the sliding groove and the sliding strip, the sliding trajectory of the protective cover is limited.

[0009] The protective cover is equipped with a stop bar located above the mounting shell. The stop bar is designed to ensure that the protective cover can be hung on the mounting shell and will not fall off.

[0010] The protective cover has a groove, and the alarm is located inside the groove. The groove is designed to minimize the impact of the protective cover on the propagation of the alarm sound.

[0011] The beneficial effects of this utility model are: By setting up a monitoring structure, if the nuts at the connection points of the segmented tank become loose, it will cause a slight relative separation between the upper and middle tanks, and between the middle and lower tanks. This will cause the lower flange, mounting block, threaded rod, and contact plate to move down synchronously, causing the contact plate to disengage from the contact switch. After the contact switch resets, the circuit is turned on, powering the alarm and triggering it to sound, promptly reminding staff to inspect the loose parts and prevent the risk of gas leakage from escalating. By setting up an anti-accidental triggering component, after the monitoring structure is debugged, align the slider on the inside of the protective cover with the slide groove on the mounting shell, and slide the protective cover down along the slide groove until the protective cover completely covers the rotating block, threaded rod, contact plate, and contact switch area. This structure minimizes the risk of accidental alarm triggering caused by personnel accidentally touching the rotating block, threaded rod, or contact switch. Attached Figure Description

Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0017] Reference Figure 1-5 A segmented tank connection structure for a gas storage tank includes an upper tank 1, a middle tank 2, and a lower tank 3, which are detachably assembled and connected; an upper flange 4 is welded to both the upper tank 1 and the middle tank 2; and a lower flange 5 is welded to both the middle tank 2 and the lower tank 3. Two sets of monitoring structures 6 are installed on the upper tank 1, the middle tank 2, and the lower tank 3. Each set of monitoring structures 6 includes a mounting shell 601 and a mounting block 605. The top of the upper flange 4 is installed on the mounting shell 601, and the mounting block 605 is installed on the bottom of the lower flange 5 for fixing the position of the mounting shell 601 and the mounting block 605. An alarm 602 is installed on the mounting shell 601. A power supply 604 is installed on the inside of the mounting shell 601. A contact switch 603 is installed at the bottom of the mounting shell 601. A threaded rod 606 is threaded through the mounting block 605. A touch plate 607 is installed at the top of the threaded rod 606. The power supply 604, the alarm 602, and the contact switch 603 are electrically connected. According to the above technical solution, specifically, after the segmented tank body is assembled, by rotating the threaded rod 606, the threaded engagement between it and the mounting block 605 is used to drive the top touch plate 607 to move upward until the touch plate 607 forms a stable pressing contact with the contact switch 603 at the bottom of the mounting shell 601; at this time, the circuit consisting of the power supply 604, the alarm 602, and the contact switch 603 is in the open state, the alarm 602 remains silent, indicating that the monitoring structure 6 has entered the normal monitoring state. During long-term use, if the nuts at the connection points of the segmented tank become loose, it will cause a slight relative separation between the upper tank 1 and the middle tank 2, and between the middle tank 2 and the lower tank 3. This will cause the lower flange 5, mounting block 605, threaded rod 606, and touch plate 607 to move down synchronously, causing the touch plate 607 to disengage from the squeezing contact of the contact switch 603. After the contact switch 603 resets, the circuit is turned on, and the power supply 604 supplies power to the alarm 602. The alarm 602 will then sound, promptly reminding staff to inspect the loose parts and prevent the risk of gas leakage from escalating. Among them, the contact switch 603 adopts the J402-S164B intelligent pressure control switch produced by Xi'an Lantian Hengyuan Hydropower Equipment Co., Ltd., the alarm 602 adopts the TankAlarm918 series product from Morrison Brothers, and the MO918SB01282B lithium battery produced by Morrison Brothers. The circuit connection method of the three can be reasonably set according to the actual situation, and the signal transmission method of the three is the existing technology.

[0018] Reference Figure 3 A rotating block 608 is installed at the bottom of the threaded rod 606. By rotating the rotating block 608, the threaded rod 606 can be rotated, which helps to facilitate the rotation of the threaded rod 606.

[0019] Reference Figure 3-5The mounting housing 601 is equipped with an anti-accidental activation component 7, which includes a protective cover 702 slidably connected to the mounting housing 601. The protective cover 702 covers the rotating block 608, threaded rod 606, touch plate 607, and contact switch 603 to minimize accidental contact and prevent false alarms from the alarm 602. The mounting housing 601 has a sliding groove 701, and a sliding strip 703 is installed on the inner side of the protective cover 702. The sliding strip 703 is slidably connected to the mounting housing 601 through the sliding groove 701. A stop bar 704 is installed on the protective cover 702. The stop bar 704 is located above the mounting housing 601 and can push the protective cover 702 upward to expose the rotating block 608, threaded rod 606, touch plate 607, and contact switch 603 and other related components for easy maintenance. According to the above technical solution, specifically, after the monitoring structure 6 is debugged, the slide bar 703 on the inner side of the protective cover 702 is aligned with the slide groove 701 on the mounting shell 601, and the protective cover 702 is slid downward along the slide groove 701 until the protective cover 702 completely covers the area of ​​the rotating block 608, the threaded rod 606, the touch plate 607, and the contact switch 603. At this time, the stop bar 704 at the top of the protective cover 702 contacts the upper edge of the mounting shell 601, forming a limiting support to prevent the protective cover 702 from slipping due to gravity. This structure minimizes the risk of accidental alarm triggering caused by personnel accidentally touching the rotating block 608, the threaded rod 606, or the contact switch 603. When it is necessary to repair the monitoring structure 6, the protective cover 702 is pushed upward, and the slide bar 703 moves upward along the slide groove 701 to expose the internal components. The operation is convenient and does not affect the structural integrity.

[0020] Reference Figure 4 The protective cover 702 has a groove 705, and the alarm 602 is located inside the groove 705. The presence of the groove 705 is to minimize the impact of the protective cover 702 on the propagation of the alarm 602.

[0021] Working principle: The segmented tank connection structure of the gas storage tank, after the segmented tank is assembled, rotates the threaded rod 606, and uses its threaded engagement with the mounting block 605 to drive the top touch plate 607 to move upward until the touch plate 607 forms a stable pressing contact with the contact switch 603 at the bottom of the mounting shell 601; at this time, the circuit consisting of the power supply 604, the alarm 602, and the contact switch 603 is in the open state, the alarm 602 remains silent, indicating that the monitoring structure 6 has entered the normal monitoring state. During long-term use, if the nuts at the connecting parts of the segmented tank become loose, it will cause a slight relative separation between the upper tank 1 and the middle tank 2, and between the middle tank 2 and the lower tank 3. This will cause the lower flange 5, mounting block 605, threaded rod 606, and touch plate 607 to move down synchronously, causing the touch plate 607 to disengage from the squeezing contact of the contact switch 603. After the contact switch 603 resets, the circuit is turned on, and the power supply 604 supplies power to the alarm 602. The alarm 602 will then sound, promptly reminding staff to inspect the loose parts and prevent the risk of gas leakage from escalating.

[0022] The segmented tank connection structure of the gas storage tank allows for easy operation after the monitoring structure 6 is debugged. The sliding strip 703 inside the protective cover 702 is aligned with the sliding groove 701 on the mounting shell 601. The protective cover 702 is then slid downwards along the sliding groove 701 until it completely covers the rotating block 608, threaded rod 606, touch plate 607, and contact switch 603. At this point, the stop bar 704 at the top of the protective cover 702 contacts the upper edge of the mounting shell 601, forming a limiting support to prevent the protective cover 702 from slipping due to gravity. This structure minimizes the risk of accidental alarm triggering caused by personnel accidentally touching the rotating block 608, threaded rod 606, or contact switch 603. When maintenance of the monitoring structure 6 is required, the protective cover 702 is pushed upwards, and the sliding strip 703 moves upwards along the sliding groove 701, exposing the internal components. This convenient operation does not affect the structural integrity.
