Description

Technical Field

[0001] This invention relates to the field of hydrostatic pressure test protection. More specifically, this invention relates to a modular, spliced ​​hydrostatic pressure test protection device and its construction method. Background Technology

[0002] Hydrostatic testing is a crucial step in verifying the strength and safety of pressure-bearing equipment. During the test, the equipment is filled with liquid and pressurized to several times its operating pressure, posing a risk of rupture, jetting, or even explosion due to material defects, fatigue, or other reasons, thus posing a significant threat to on-site personnel and equipment. Existing protective measures mostly involve constructing temporary retaining walls or fixed barriers, which suffer from insufficient protective strength, lengthy construction time, and inconvenient repair or the need for complete replacement after localized damage. Therefore, there is an urgent need for a standardized protective device that combines high-strength protection, modular design, and rapid localized replacement to improve the safety and efficiency of testing. Summary of the Invention

[0003] To achieve these objectives and other advantages according to the invention, a preferred embodiment of the invention provides a modular splicing hydrostatic test protection device, comprising multiple rectangular protective plates and multiple connecting components; The multiple protective plates are detachably connected to each other in the horizontal and vertical directions through the connecting components to form a grid-like protective structure; The connecting component is disposed at the corresponding edge of an adjacent protective plate and is configured to transmit and distribute the impact force to the adjacent protective plate connected to it when a single protective plate is impacted. Each of the aforementioned protective plates can be independently removed and replaced from the protective structure without removing the other protective plates.

[0004] Preferably, the connecting assembly includes a connecting portion disposed at the edge of the protective plate and a fastening unit for connecting adjacent protective plate connecting portions.

[0005] Preferably, the connecting part is a connecting hole opened on the protective plate frame, a connecting lug provided on the outside of the frame, or a slot formed on the inside of the frame.

[0006] Preferably, the protective plate is provided with a plurality of pressure-responsive pressure relief units, each pressure relief unit comprising: A pressure relief channel that extends through the thickness of the protective plate; A resilient sealing plug that can be movable to block the pressure relief channel; The elastic sealing plug is supported by a pre-compressed spring and is set with an opening threshold pressure; When the fluid pressure on the outside of the protective plate exceeds the threshold, the elastic sealing plug is pushed open, opening the pressure relief channel and releasing part of the impact medium; when the pressure drops back below the threshold, the elastic sealing plug automatically resets and reseals the pressure relief channel under the action of elastic restoring force.

[0007] Preferably, the pressure relief channel is a stepped through-hole structure, consisting of an outer liquid inlet section, a middle sealing section, and an inner liquid outlet section. The inner diameter of the outer liquid inlet section is larger than the inner diameter of the middle sealing section, and the inner diameter of the middle sealing section is smaller than the inner diameter of the inner liquid outlet section. The elastic sealing plug includes a sealing head and a guide rod. The sealing head is adapted to the middle sealing section, and the outer diameter of the sealing head is slightly larger than the inner diameter of the middle sealing section. An arc-shaped guide surface is provided at the end of the sealing head facing the outer liquid inlet section. The guide rod is coaxially fixed to the sealing head away from the arc. One end of the shaped guide surface has a guide rod that passes through the inner liquid outlet section and extends to the inner side of the protective plate. The end of the inner liquid outlet section away from the middle sealing section is provided with an annular limiting plate. The pre-compression spring is sleeved on the outside of the guide rod. One end of the spring abuts against the sealing head, and the other end abuts against the stepped surface of the inner liquid outlet section. The inner wall of the inner liquid outlet section is provided with a number of guide protrusions evenly spaced along the circumference. The outer wall of the guide rod is provided with guide grooves that are adapted to the guide protrusions one by one. The guide protrusions are embedded in the guide grooves and slide in cooperation with the inner wall of the grooves.

[0008] On the other hand, another technical solution of the present invention provides a method for constructing the modular splicing hydrostatic pressure test protection device, comprising the following steps: S1. Determine the required number of protective panels and the layout of the overall protective structure based on the size of the area to be protected; S2. Determine whether a pressure-responsive pressure relief unit needs to be integrated into the corresponding protective plate based on the risk level of each area. For high-risk areas, select a protective plate equipped with a pressure relief unit, and set its opening threshold pressure to be slightly higher than the maximum expected impact pressure of the area. S3. Connect multiple protective panels sequentially in the horizontal direction using connecting components to form the bottom protective surface; S4. Based on the bottom protective surface, continue to connect the protective plates layer by layer in the vertical or horizontal expansion direction through the connecting components until a three-dimensional protective structure with a predetermined height and coverage is formed. S5. Finally tighten all connecting components.

[0009] Preferably, in step S1, before determining the number of protective plates and the layout of the protective structure, a step of conducting a hydrostatic impact risk assessment of the area to be protected is also included. Specifically, based on the hydrostatic test pressure value of the component to be tested, the type of test medium, and the surrounding environment of the area to be protected, three impact risk levels are divided into high, medium, and low. Protective plates of different thicknesses are configured for different risk levels. Thickened protective plates are configured for high-risk areas, while standard and lightweight protective plates are configured for medium and low-risk areas, respectively.

[0010] The present invention has at least the following beneficial effects: the overall grid structure of the present invention can effectively disperse local impacts and significantly improve protective safety; at the same time, the modular design allows for rapid assembly and flexible expansion through standardized plates and connectors, greatly reducing maintenance costs and replacement time, and has comprehensive advantages of excellent protective performance, convenient installation, strong scalability and efficient maintenance.

[0011] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0016] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0017] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] like Figs. 1-3 As shown, a preferred embodiment of the present invention provides a modular splicing hydrostatic test protection device, including multiple rectangular protective plates 1 and multiple connecting components 2; The plurality of protective plates 1 are detachably connected to each other in the horizontal and vertical directions by the connecting assembly 2 to form a grid-like protective structure; The connecting component 2 is disposed at the corresponding edge of the adjacent protective plate 1 and is configured to transmit and disperse the impact force to the adjacent protective plate 1 connected to it when a single protective plate 1 is impacted. Each of the protective plates 1 can be independently removed and replaced from the protective structure without removing the other protective plates.

[0020] During operation, when the hydrostatic test component ruptures and the impact medium impacts the protective plate 1, the impacted individual protective plate 1 transmits the impact force to the connecting component 2 connected to it. The connecting component 2, connected to adjacent protective plates 1 by bolts, quickly disperses the impact force to multiple surrounding protective plates 1, significantly reducing the impact force borne by a single protective plate 1 and preventing damage due to excessive local stress. When a protective plate 1 needs replacement due to wear, deformation, or damage during impact, simply unscrew the bolts and nuts connecting the edge of that protective plate 1 to adjacent protective plates 1 to independently remove it from the overall protective structure without removing the remaining intact protective plates 1. After replacing with a new protective plate 1, tighten the bolts and nuts again to restore the integrity of the protective structure. This invention decomposes the overall protective structure into multiple independent protective plate 1 units through modular splicing, utilizes the rigid connection of the connecting component 2 to achieve the dispersion and transmission of impact force, and employs a detachable design to achieve individual maintenance and replacement of the protective plates 1.

[0021] The present invention also provides the following technical solution, wherein the connecting component 2 includes a connecting portion disposed on the edge of the protective plate and a fastening unit 22 for connecting adjacent protective plates through connecting holes. The connecting portion is a connecting hole 21 opened on the frame of the protective plate, a connecting lug disposed on the outer side of the frame, or a slot formed on the inner side of the frame. This embodiment utilizes the positioning function of the fastening unit 22 to stably connect adjacent protective plates 1 into a single unit. The rigidity of the fastening unit 22 enables the transmission and dispersion of impact force between adjacent protective plates 1. Simultaneously, the detachable bolt and nut structure allows for flexible assembly and disassembly of the protective plates 1.

[0022] The present invention also provides the following technical solution: the protective plate 1 is provided with a plurality of pressure-responsive pressure relief units 3, each pressure relief unit comprising: A pressure relief channel 31 that extends through the thickness of the protective plate; A resilient sealing plug that can be movable to block the pressure relief channel; The elastic sealing plug is supported by a pre-compressed spring 34 and is set with an opening threshold pressure; When the fluid pressure on the outside of the protective plate exceeds the threshold, the elastic sealing plug is pushed open, opening the pressure relief channel and releasing part of the impact medium; when the pressure drops back below the threshold, the elastic sealing plug automatically resets and reseals the pressure relief channel under the action of elastic restoring force.

[0023] During operation, when the hydrostatic test is conducted normally, the fluid pressure acting on the outside of the protective plate 1 is within the normal range and is less than the opening threshold pressure of the pressure relief unit 3. At this time, the pre-compressed spring 34 exerts a clamping force on the elastic sealing plug, causing the elastic sealing plug to tightly seal the pressure relief channel 31, preventing the test medium from leaking through the pressure relief channel 31 and ensuring the sealing and protection effect of the protective device. When the test component ruptures, and the pressure generated by the impact medium on the outside of the protective plate 1 exceeds the opening threshold pressure, the fluid pressure acts on the outer end of the elastic sealing plug, generating an outward thrust. When this thrust is greater than the pre-compression force of the spring 34, the elastic sealing plug is pushed open, the pressure relief channel 31 is opened, and the impact medium flows from the outside of the protective plate 1 to the inside through the pressure relief channel 31, thereby discharging from the protected area, releasing part of the impact medium, and reducing the pressure borne by the protective plate 1. When the impact medium is discharged, and the pressure acting on the outside of the protective plate 1 falls back below the opening threshold pressure, the elastic restoring force of the spring 34 pushes the elastic sealing plug to reset, re-sealing the pressure relief channel 31, restoring the protective device to a sealed state, and continuing to perform its protective function. In this embodiment, the pressure-responsive pressure relief unit 3 can automatically respond to pressure changes on the outside of the protective plate 1 and release pressure in a timely manner when the pressure is abnormal, effectively reducing the impact force on the protective plate 1, preventing the protective plate 1 from being damaged due to excessive pressure, and improving the impact resistance and safety of the protective device; moreover, the automatic reset function ensures that the protective device can quickly restore the sealing state after pressure relief; multiple pressure relief units 3 are evenly distributed, which can achieve uniform pressure relief, avoid local pressure concentration, further improve the reliability of the protective device, and adapt to impact scenarios of different intensities.

[0024] The present invention also provides the following technical solution: the pressure relief channel 31 is a stepped through-hole structure, consisting of an outer liquid inlet section 311, a middle sealing section 312, and an inner liquid outlet section 313. The inner diameter of the outer liquid inlet section 311 is larger than the inner diameter of the middle sealing section 312, and the inner diameter of the middle sealing section 312 is smaller than the inner diameter of the inner liquid outlet section 313. The elastic sealing plug includes a sealing head 32 and a guide rod 33. The sealing head 32 is adapted to the middle sealing section 311, and the outer diameter of the sealing head 32 is slightly larger than the inner diameter of the middle sealing section 311. An arc-shaped guide surface 3 is provided at the end of the sealing head 32 facing the outer liquid inlet section. 4; The guide rod 33 is coaxially fixed to the end of the sealing head 32 away from the arc-shaped guide surface. The guide rod 33 passes through the inner liquid outlet section and extends to the inner side of the protective plate 1. The end of the inner liquid outlet section away from the middle sealing section is provided with an annular limiting plate. The pre-compressed spring 34 is sleeved on the outside of the guide rod 33. One end of the spring 34 abuts against the sealing head 32, and the other end abuts against the stepped surface of the inner liquid outlet section. The inner wall of the inner liquid outlet section is provided with a number of guide protrusions evenly spaced along the circumference. The outer wall of the guide rod is provided with guide grooves that are adapted to the guide protrusions one by one. The guide protrusions are embedded in the guide grooves and slide in cooperation with the inner wall of the grooves.

[0025] During operation, when the hydrostatic test is being carried out normally, the fluid pressure outside the protective plate 1 is within the normal range and is less than the opening threshold pressure. The pre-compressed spring 34 generates a continuous clamping force on the sealing head 32. Since the diameter of the sealing head 32 is slightly larger than the inner diameter of the middle sealing section 312, the sealing head 32 fits tightly against the inner wall of the middle sealing section 312, thereby sealing the pressure relief channel 31 and preventing leakage of the test medium. When the test component ruptures and the pressure exerted by the impact medium on the outer side of the protective plate 1 exceeds the opening threshold pressure, the impact medium enters the pressure relief channel 31 through the outer inlet section 311. It then acts evenly on the end face of the sealing head 32 via the arc-shaped guide surface 34, generating an outward thrust. When this thrust exceeds the pre-compression force of the spring 34, the sealing head 32 is pushed open, causing the guide rod 33 to move axially inward. The spring 34 is further compressed, and the pressure relief channel 31 is opened. The impact medium then passes sequentially through the outer inlet section 311, the middle sealing section 312, and the inner outlet section 313, exiting the protected area, releasing some of the impact medium, and reducing the pressure on the protective plate 1. During this process, the sliding cooperation between the guide convex strip and the guide groove ensures that the guide rod 33 and the sealing head 32 move axially without rotation or displacement, guaranteeing accurate repositioning of the sealing head 32. When the pressure drops below the opening threshold pressure, the elastic restoring force of the spring 34 pushes the sealing head 32 to move axially outward until the sealing head 32 re-embeds into the middle sealing section 312 and fits tightly, thus resealing the pressure relief channel 31. The guide rod 33 resets under the guidance of the guide protrusion and guide groove. The annular limiting plate restricts the maximum range of motion of the guide rod 33, preventing the sealing head 32 from being completely pushed out of the pressure relief channel 31, ensuring that the pressure relief unit 3 can be reused. This invention provides reasonable installation space for the sealing head 32, guide rod 33, and spring 34 through the stepped pressure relief channel 31 structure design. The sealing is achieved by the interference fit between the sealing head 32 and the middle sealing section 312. The opening threshold pressure is set by the pre-compression force of the spring 34. The smooth movement of the elastic sealing plug is ensured by the guide structure, realizing the automatic opening, pressure relief, and reset of the pressure relief unit. Furthermore, the arc-shaped guide surface 34 ensures that the impact medium acts evenly on the sealing head 32, avoiding localized damage due to force; the guide structure ensures that the elastic sealing plug moves smoothly and will not shift or get stuck, thus improving the reliability of the pressure relief unit 3.

[0026] The present invention also provides the following technical solution, specifically, the construction method of the modular splicing hydrostatic pressure test protection device includes the following steps: S1. Determine the required number of protective panels and the layout of the overall protective structure based on the size of the area to be protected; S2. Determine whether a pressure-responsive pressure relief unit needs to be integrated into the corresponding protective plate based on the risk level of each area. For high-risk areas, select a protective plate equipped with a pressure relief unit, and set its opening threshold pressure to be slightly higher than the maximum expected impact pressure of the area. S3. Connect multiple protective panels sequentially in the horizontal direction using connecting components to form the bottom protective surface; S4. Based on the bottom protective surface, continue to connect the protective plates layer by layer in the vertical or horizontal expansion direction through the connecting components until a three-dimensional protective structure with a predetermined height and coverage is formed. S5. Finally tighten all connecting components.

[0027] The above technical solution uses a modular splicing method to assemble multiple independent protective panels 1 into a complete three-dimensional protective structure. The number and type of protective panels 1 are reasonably configured according to the size and risk level of the area to be protected, ensuring that the protective structure can fully cover the area to be protected and achieve targeted protection. The detachable connection method of the connecting component 2 facilitates the splicing and adjustment of the protective panels 1, ensuring the flexibility and stability of the protective structure.

[0028] The present invention also provides the following technical solution: in step S1, before determining the number of protective plates and the layout of the protective structure, a step of assessing the hydrostatic impact risk of the area to be protected is also included. Specifically, based on the hydrostatic test pressure value of the component to be tested, the type of test medium, and the surrounding environment of the area to be protected, three impact risk levels are divided into high, medium, and low. Protective plates of different thicknesses are configured for different risk levels. Thickened protective plates are configured for high-risk areas, and standard and lightweight protective plates are configured for medium and low-risk areas, respectively.

[0029] For example, a factory conducted a hydrostatic test on a high-pressure storage tank with a test pressure of 30 MPa. Based on the high test pressure, the medium being water, and the surrounding environment, the protected area was divided into three risk levels: high, medium, and low. The area immediately adjacent to the tank front, where personnel might approach, was designated a high-risk zone, equipped with thickened protective plates (e.g., 30 mm thick steel plates) and integrated with a pressure-responsive pressure relief unit. Its opening threshold was slightly higher than the test pressure (e.g., set at 35 MPa) to ensure automatic energy release in case of abnormal overpressure. The areas on both sides of the tank with instruments but fewer personnel were designated medium-risk zones, using standard protective plates (e.g., 20 mm thick). Open passageways more than 3 meters away were low-risk zones, requiring only lightweight protective plates (e.g., 10 mm thick) to block splashes. This tiered configuration ensured the safety of critical areas while avoiding an overly cumbersome overall structure, demonstrating the advantages of modular protective devices: customization, flexibility, and efficiency. During subsequent installation, protective plates of different specifications could be quickly assembled using connecting components, and damaged sections could be replaced individually without disassembling the entire structure.

[0030] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
