Description

Technical Field

[0001] This utility model relates to the field of oil tank leak detection technology, specifically a leak detection probe for a fully liquid-contact floating roof / floor box that can be installed quickly. Background Technology

[0002] In the fields of petrochemicals, energy storage, and environmental governance, large atmospheric pressure storage tanks undertake the task of storing critical media. Among them, the fully submerged floating roof, as a highly efficient tank sealing device, covers the liquid surface inside the tank through a floating box structure that is completely immersed in the stored liquid. This can significantly reduce the fugitive emissions of volatile organic compounds, lower the risk of fire and explosion, and avoid media contamination. It is the mainstream tank sealing technology under current environmental and safety standards.

[0003] Most storage tanks currently in use are equipped with online monitoring systems based on fiber optic gratings, pressure sensors, or capacitance detection. These systems detect changes in physical parameters caused by leakage by arranging sensor arrays on the floating roof or at the bottom of the tank. However, such systems have the following problems: sensors need to be pre-embedded during the manufacturing or modification of the floating roof, or drilled and welded to the existing floating roof, which may damage the structural integrity of the floating box and affect buoyancy performance. Utility Model Content

[0004] The purpose of this invention is to provide a leak detection probe for a fully liquid-contact floating roof or pontoon that can be installed quickly, in order to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak detection probe for a fully liquid-contact floating roof / float box that can be quickly installed, comprising a floating roof, an outer isolation cover, a base plate, and an insulating slider. An O-ring is provided on the outer side of the floating roof, and positioning grooves are distributed in a ring around its outer side. A clamping mechanism is provided directly above the floating roof. The clamping mechanism adjusts the distance between the outer isolation cover and the base plate by driving the outer isolation cover to move axially along the top edge of the base plate. This adjustable distance allows for simultaneous clamping and limiting of the bottom and top edges of sensing housings of different sizes. A displacement mechanism is provided below the base plate. This mechanism, through the displacement of the insulating slider at its bottom along the guide rail outside the positioning groove, can synchronously drive the sensor probe to move; or, through a linkage structure, the sensor probe and the insulating slider can be detached and separated integrally from the positioning groove.

[0006] As a preferred technical solution, the clamping mechanism includes a sealing ring, a docking groove, a support column, a sensing housing, an outer isolation cover, positioning holes, and a rectangular sleeve. The sealing ring is disposed through the top of the outer isolation cover. The docking groove is distributed in a "U" shape on the surface of the bottom support plate. The sensing housing is disposed directly above the bottom support plate. The outer isolation cover is disposed directly above the sensing housing. The positioning holes are evenly spaced on one side of the support column and are opened on one side of the rectangular sleeve.

[0007] As a preferred technical solution, an annular sealing groove is provided at the top of the outer isolation cover, and a sealing ring is embedded and installed inside it; after being compressed and deformed, the sealing ring forms a radial sealing contact with the outer wall of the sensing housing.

[0008] As a preferred technical solution, a rectangular sleeve is machined on the back of the outer isolation cover. The sleeve serves as a connection interface and has a through hole that matches the cross-section of the adjustable arm. The outer isolation cover forms a through-sliding connection with the adjustable arm through the through hole of the rectangular sleeve.

[0009] As a preferred technical solution, the switching mechanism includes a sensor probe, a positioning groove, a base plate, an adjusting arm, an insulating slider, and a limiting hole. The sensor probe is embedded and fixedly mounted in the center of the bottom end face of the sensing housing. An insulating slider is connected to the outside of the positioning groove. A limiting hole is opened through the outside of the insulating slider. The insulating slider is located at the inner end of the floating plate. An adjusting arm is welded directly above the base plate.

[0010] As a preferred technical solution, the upper surface of the base plate is machined with a U-shaped connecting groove along the transverse direction, and the bottom end of the outer isolation cover is embedded in the U-shaped groove to form a snap-fit ​​positioning connection.

[0011] As a preferred technical solution, a limiting hole is opened through one side wall of the insulating slider along the thickness direction, and a bolt inserted through the limiting hole is fastened to the mounting hole on the outside of the floating plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves adaptive fixing of the sensing housing through a clamping mechanism: the outer isolation cover is axially displaced along the top of the bottom support plate under the driving action of the adjusting arm, adjusting the distance between the outer isolation cover and the bottom support plate until the distance matches the height of the sensing housing, thereby forming a clamping limit when the bottom end of the sensing housing contacts the bottom support plate and the top end contacts the outer isolation cover. The clamping mechanism can be adapted to sensing housings of different sizes and specifications without customized adjustments, significantly improving installation efficiency.

[0013] 2. This utility model's probe achieves efficient detection and rapid maintenance of floating box leakage through adjustable limiting of the clamping mechanism, displacement transmission of the displacement drive, and guide detachment of the insulating slider. When maintaining or replacing the probe, the reverse drive moves the insulating slider along the guide rail to a specific position, and pushes the sensing housing upward through the linkage structure, causing its bottom end to detach from the support of the bottom plate. At the same time, the outer isolation cover moves upward due to the sliding cooperation between the rectangular sleeve block and the adjustable arm, finally completely detaching the sensor probe from the floating plate positioning groove, achieving rapid disassembly.

Detailed Implementation

[0016] 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.

[0017] Example: Figures 1 to 4 As shown, this utility model provides the following technical solution: a leak detection probe for a fully liquid-contact floating roof / float box that can be quickly installed, including a floating roof 1, an outer isolation cover 6, a bottom support plate 7, and an insulating slider 15. An O-ring 2 is provided on the outer side of the floating roof 1, and positioning grooves 3 are distributed in a ring on the outer side of the floating roof 1. A clamping mechanism 11 is provided directly above the floating roof 1. The clamping mechanism 11 adjusts the distance between the outer isolation cover 6 and the bottom support plate 7 by driving the outer isolation cover 6 to move axially along the top of the bottom support plate 7. The adjustable distance is used to simultaneously clamp and limit the bottom and top of the sensing housing 5 of different sizes and specifications. A displacement mechanism 16 is provided below the bottom support plate 7. This mechanism can synchronously drive the sensor probe 12 to move by moving the insulating slider 15 at its bottom along the guide rail outside the positioning groove 3; or the sensor probe 12 and the insulating slider 15 can be detached and separated from the positioning groove 3 in an integrated manner through a linkage structure.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the clamping mechanism 11 includes a sealing ring 13, a docking groove 14, a support column 4, a sensing housing 5, an outer isolation cover 6, positioning holes 9, and a rectangular sleeve block 10. The sealing ring 13 is disposed through the top of the outer isolation cover 6. The docking groove 14 is distributed in a "U" shape on the surface of the bottom support plate 7. The sensing housing 5 is disposed directly above the bottom support plate 7, and the outer isolation cover 6 is disposed directly above the sensing housing 5. The positioning holes 9 are evenly spaced on one side of the support column 4, and the positioning holes 9 are opened on one side of the rectangular sleeve block 10. The top of the outer isolation cover 6 has an annular sealing groove, in which the sealing ring 13 is embedded and installed. After being compressed and deformed, the sealing ring 13 forms a radial sealing contact with the outer wall of the sensing housing 5. The back of the outer isolation cover 6 is machined with a rectangular sleeve block 10, which serves as a connection interface and has a through hole adapted to the cross-section of the adjusting arm 8. The outer isolation cover 6 forms a through sliding connection with the adjusting arm 8 through the through hole of the rectangular sleeve block 10.

[0019] Among them: the sealing ring 13 in the annular sealing groove at the top of the outer isolation cover 6 is radially sealed and abutted against the outer wall of the sensing housing 5 after being clamped and squeezed, preventing oil, water vapor or impurities in the storage tank from entering the interior; the insulating slider 15 is made of engineering plastic or ceramic material to block the electromagnetic interference of the metal float 1 and avoid sensor signal distortion.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the switching mechanism 16 includes a sensor probe 12, a positioning groove 3, a base plate 7, an adjusting arm 8, an insulating slider 15, and a limiting hole 17. The sensor probe 12 is axially fixed and embedded in the center of the bottom end face of the sensing housing 5. The insulating slider 15 is connected to the outside of the positioning groove 3. The limiting hole 17 is opened through the outside of the insulating slider 15. The insulating slider 15 is set at the inner end of the floating plate 1. The adjusting arm 8 is welded directly above the base plate 7. The upper end face of the base plate 7 is machined with a U-shaped connecting groove 14 along the transverse direction. The bottom end of the outer isolation cover 6 is embedded in the U-shaped groove to form a snap-fit ​​positioning connection. The limiting hole 17 is opened through one side wall of the insulating slider 15 along the thickness direction. The limiting hole 17 is fastened to the mounting hole on the outside of the floating plate 1 by a bolt passing through the limiting hole 17.

[0021] Specifically, the rectangular sleeve 10 and the adjustable arm 8 can be engaged by snapping together or the fixing bolts of the insulating slider 15 can be loosened to quickly separate the sensor probe 12 and the outer isolation cover 6 from the floating plate 1 in one piece without damaging the sealing structure. A single person can complete the probe replacement or mechanism maintenance in a short time. The U-shaped locking groove 14 of the outer isolation cover 6 and the bottom support plate 7 is embedded in the U-shaped groove. Without disassembling the floating plate 1 or damaging the original structure of the storage tank, the probe can be assembled while the storage tank is in operation, avoiding production stoppage losses.

[0022] The working principle of this utility model is as follows: The insulating slider 15 slides along the guide rail of the positioning groove 3 on the outer side of the floating plate 1 and is fastened to the preset mounting hole of the floating plate 1 by the bolt of the limiting hole 17, fixing the bottom plate 7 and the clamping mechanism 11 below the floating plate 1. The sensor probe 12 built into the sensing housing 5 is placed above the bottom plate 7. The height of the outer isolation cover 6 is adjusted by the adjusting arm 8. The rectangular sleeve 10 on the back of the outer isolation cover 6 slides along the adjusting arm 8 until the bottom end of the outer isolation cover 6 is embedded in the U-shaped docking groove 14 of the bottom plate 7 to form a snap-on positioning. At this time, the distance between the outer isolation cover 6 and the bottom support plate 7 is adjusted to match the height of the sensing housing 5, so that the bottom end of the sensing housing 5, the bottom support plate 7 supports and presses against the top outer isolation cover 6 while clamping and limiting the position; the sealing ring 13 at the top of the outer isolation cover 6 is radially sealed and abutted against the outer side wall of the sensing housing 5 under compression. At the bottom center of the sensing housing 5, a sensor probe 12 is embedded in an axially fixed manner. Its detection end protrudes downward from the outside of the housing and is directly aligned with the floating box area below the floating plate 1. If the leaking medium is liquid, the sensor probe 12 senses a sudden change in conductivity or dielectric constant by contacting the medium, triggering a detection signal. If the leaking medium is gaseous, the sensor probe 12 generates an alarm signal by detecting abnormal gas concentration. After the detection signal is processed by the internal circuit, it is transmitted to the external monitoring system in real time to realize dynamic monitoring and early warning of floating box leakage. The insulating slider 15 slides along the guide rail outside the positioning groove 3, synchronously driving the sensor probe 12 connected to it to produce a vertical displacement. The adjusting arm 8 and the through hole of the rectangular sleeve block 10 on the back of the outer isolation cover 6 form a through sliding connection, allowing the outer isolation cover 6 to rotate a small range along the adjusting arm 8. With the elastic clamping force of the clamping mechanism 11, the angle of the sensing housing 5 can be finely adjusted to optimize the probe detection direction. If only the sensor probe 12 needs to be replaced, it can be directly disassembled from the bottom of the sensing housing 5. If the clamping mechanism 11 or the switching mechanism 16 needs to be repaired, the fixing bolts of the insulating slider 15 can be loosened to separate the bottom plate 7, the outer isolation cover 6 and other components, realizing modular maintenance.
