Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring technology, and more specifically, to a multi-point settlement monitoring device for LNG storage tanks. Background Technology

[0002] The LNG storage tank multi-point settlement monitoring device directly displays settlement value changes through scale lines. Its excellent monitoring effect ensures safety and accuracy. The scale line design allows on-site personnel to directly read settlement values ​​without complicated instruments, avoiding reading errors that may be introduced by traditional leveling instruments or manual recording.

[0003] Among the existing publicly available documents, patent publication number CN218524151U discloses a semi-underground LNG storage tank settlement monitoring system. This technology differs from traditional above-ground LNG storage tank settlement monitoring methods, which rely on manual, periodic measurement of settlement data using a portable horizontal sliding inclinometer. Instead, it employs a fixed horizontal inclinometer, enabling automatic and uninterrupted data acquisition and avoiding frequent on-site operations. However, this technology still has the following problems.

[0004] When LNG storage tanks are in use, settlement points need to be monitored. However, there are multiple settlement points, and it is difficult to adjust and monitor multiple points laterally and longitudinally during settlement, resulting in poor adjustability of settlement monitoring. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a multi-point settlement monitoring device for LNG storage tanks, comprising a support frame, a guide rod fixed to the inner wall of the support frame, two adjusting sleeves slidably connected to the outer wall of the guide rod, and an adjusting assembly installed on the adjusting sleeves. The adjusting assembly is used to adjust the distance between the two adjusting sleeves, and the adjusting assembly includes: A sleeve plate is fixed to one side of the adjusting sleeve, and a support rod is fixed to one side of the inner wall of the sleeve plate; A sleeve plate is slidably connected to the outer wall of the support rod. The sleeve plate is used to guide the movement of the sleeve plate. A positioning sleeve is fixed at one end of the sleeve plate. A monitoring scale is slidably installed on the inner wall of both the positioning sleeve and the sleeve plate. The graduation lines are set on the outer wall of the monitoring ruler.

[0006] In a preferred embodiment, the support frame is used to guide the sliding of the adjusting sleeves, and the two adjusting sleeves are symmetrically arranged about the support frame.

[0007] In a preferred embodiment, one end of the support rod has a circular vertical cross-section, and the other end of the support rod has a polygonal vertical cross-section.

[0008] In a preferred embodiment, a gap is provided between the two monitoring rulers, and the plurality of scale lines are arranged in a rectangular distribution.

[0009] In a preferred embodiment, a locking bolt is threaded onto the other side of the adjusting sleeve, the locking bolt being used to press and lock the guide rod.

[0010] In a preferred embodiment, a threaded fixing bolt is embedded at the top of the sleeve plate, and the fixing bolt can be used to press and lock the support rod.

[0011] In a preferred embodiment, a contact block is fixed to the bottom end of the monitoring ruler, and the cross-sectional area of ​​the contact block is larger than the cross-sectional area of ​​the monitoring ruler. A mounting bracket is fixed to the lower surface of the support frame, near its central position.

[0012] In a preferred embodiment, a limit block is fixed at the top of each monitoring ruler, and a counterweight column and a counterweight sleeve are fixed on the upper surface of the limit block, with the counterweight sleeve sleeved on the outer wall of the counterweight column. A counterweight ring is fixedly connected to the outer wall of the counterweight column and at the top of the counterweight sleeve.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts an adjustment component. Two adjustment sleeves respectively drive the distance between the two sleeve plates to increase, two support rods respectively drive the distance between the two sleeve plates to increase, and two positioning sleeves respectively drive the distance between the two monitoring rulers to increase. After the lateral distance between the two adjustment sleeves is adjusted, the sleeve plates slide along the outer wall of the support rods. The sleeve plates drive the positioning sleeves to move, and the monitoring rulers drive the contact blocks to move. In this way, the distance between the positioning sleeves and the sleeve plates is adjusted longitudinally, which can realize lateral and longitudinal adjustment monitoring of multiple points, and the adjustable applicability of settlement monitoring is wider.

[0014] 2. This utility model uses a counterweight column to counterweight the limiting block, and a counterweight sleeve to counterweight the limiting block. The limiting block provides a large counterweight force to the monitoring ruler, and the monitoring ruler moves quickly downward along the inner wall of the positioning sleeve to achieve rapid counterweight settlement monitoring, making settlement monitoring faster.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 - Figure 5 The present invention relates to a multi-point settlement monitoring device for an LNG storage tank. The device is equipped with an adjustment component, which allows for longitudinal adjustment of the distance between the positioning sleeve 7 and the sleeve plate 4. This enables lateral and longitudinal adjustment monitoring of multiple points, thus broadening the applicability of settlement monitoring. The specific structural configuration of the adjustment component is as follows.

[0023] In this embodiment, as Figure 1 - Figure 3As shown, a guide rod 2 is fixed to the inner wall of the support frame 1. Two adjusting sleeves 3 are slidably connected to the outer wall of the guide rod 2. An adjusting assembly is installed on the adjusting sleeve 3. The adjusting assembly is used to adjust the distance between the two adjusting sleeves 3. The adjusting assembly includes: a sleeve plate 4, fixed to one side of the adjusting sleeve 3, with a support rod 5 fixed to one side of the inner wall of the sleeve plate 4; a connecting sleeve plate 6, slidably connected to the outer wall of the support rod 5, with the sleeve plate 4 used to guide the movement of the connecting sleeve plate 6; a positioning sleeve 7 fixed to one end of the connecting sleeve plate 6; and monitoring scales 8 slidably installed on the inner walls of both the positioning sleeve 7 and the sleeve plate 4; and scale lines 9, opened on the outer wall of the monitoring scales 8. The support frame 1 is used to guide the sliding of the adjusting sleeves 3. The two adjusting sleeves 3 are symmetrically arranged about the support frame 1. One end of the support rod 5 has a circular vertical cross-section, and the other end has a polygonal vertical cross-section. There is a gap between the two monitoring scales 8, and multiple scale lines 9 are arranged in a rectangular distribution.

[0024] In this embodiment, as Figure 2 As shown, a locking bolt 10 is threadedly connected to the other side of the adjusting sleeve 3. The locking bolt 10 is used to press and lock the guide rod 2. By rotating the locking bolt 10, the locking bolt 10 engages with the thread of the adjusting sleeve 3, thereby improving the locking operation of the contact block 12.

[0025] In this embodiment, as Figure 2 As shown, a threaded fixing bolt 11 is embedded at the top of the sleeve plate 6, and the fixing bolt 11 can be used to press and lock the support rod 5. By rotating the fixing bolt 11, the fixing bolt 11 is pressed against the outer wall of the support rod 5, providing a pressing and locking force.

[0026] In this embodiment, as Figure 2 - Figure 5 As shown, a contact block 12 is fixed to the bottom of the monitoring ruler 8. The cross-sectional area of ​​the contact block 12 is larger than that of the monitoring ruler 8. The monitoring ruler 8 drives the contact block 12 to move, and the contact block 12 fits against the monitoring point of the LNG storage tank. A mounting bracket 17 is fixed to the lower surface of the support frame 1 near its middle position. After installation, the mounting bracket 17 provides support to the support frame 1, improving the stability of the support frame 1.

[0027] When using this LNG storage tank multi-point settlement monitoring device, the mounting bracket 17 is fixed to the base by inserting mounting bolts into the holes in the mounting bracket 17. By pulling the distance between the two adjusting sleeves 3 laterally, the adjusting sleeves 3 move to the right along the outer wall of the guide rod 2, increasing the distance between the two adjusting sleeves 3. The two adjusting sleeves 3 then increase the distance between the two sleeve plates 4, which in turn increase the distance between the two support rods 5, which in turn increase the distance between the two connecting sleeve plates 6, which in turn increase the distance between the two positioning sleeves 7, and finally, the two positioning sleeves 7 increase the distance between the two monitoring scales 8. After adjusting the lateral distance between the two adjusting sleeves 3, the locking bolt 10 is rotated. The locking bolt 10 engages with the threaded adjusting sleeve 3, pressing against the guide rod 2 to fix the position of the adjusting sleeve 3.

[0028] By moving the sleeve plate 6, the sleeve plate 6 slides along the outer wall of the support rod 5 and is guided to slide along the inner wall of the sleeve plate 4. The sleeve plate 6 drives the positioning sleeve 7 to move, the positioning sleeve 7 drives the monitoring scale 8 to move, and the monitoring scale 8 drives the contact block 12 to move. In this way, the distance between the positioning sleeve 7 and the sleeve plate 4 is adjusted longitudinally. After adjustment, the fixing bolt 11 is rotated, and the fixing bolt 11 presses against the outer wall of the support rod 5 to fix the sleeve plate 6. In this way, the lateral and longitudinal spacing of multiple sleeve plates 4 can be adjusted. In this way, multiple contact blocks 12 are located at multiple points in the LNG storage tank. When the LNG storage tank settles, the contact block 12 drives the monitoring scale 8 to move downward. The monitoring scale 8 is guided downward along the inner wall of the positioning sleeve 7, and the scale line 9 on the monitoring scale 8 can be adjusted downward. When the position of the scale line 9 changes, it indicates that a settlement problem has occurred. This enables multi-point settlement monitoring.

[0029] In this embodiment, as Figure 4 As shown, a limit block 13 is fixed at the top of each monitoring ruler 8. A counterweight column 14 and a counterweight sleeve 16 are fixed on the upper surface of the limit block 13, and the counterweight sleeve 16 is sleeved on the outer wall of the counterweight column 14. A counterweight ring 15 is fixedly connected to the outer wall of the counterweight column 14 and at the top of the counterweight sleeve 16.

[0030] When this LNG storage tank multi-point settlement monitoring device is in use, the counterweight column 14 is used to counterweight the limiting block 13, and the counterweight ring 15 is used to counterweight the counterweight sleeve 16. The counterweight sleeve 16 is used to counterweight the limiting block 13. In this way, the limiting block 13 provides a large counterweight force to the monitoring ruler 8. When the LNG storage tank sinks, the monitoring ruler 8 moves rapidly downward along the inner wall of the positioning sleeve 7.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
