Description

Technical Field

[0001] This utility model relates to the field of multi-purpose integrated testing equipment, specifically to an environmental simulation chamber for multi-purpose integrated testing. Background Technology

[0002] In deep-sea oil and gas exploration and development, directional drilling equipment is a key piece of equipment, and its performance and reliability directly affect the safety and efficiency of exploration operations. However, the deep-sea environment is extremely complex and harsh, and the equipment must withstand the combined effects of various extreme factors such as high temperature, high pressure, high-intensity vibration, and corrosive media for extended periods during actual operations. High temperatures may originate from geothermal gradients or heat generated during equipment operation, while vibrations are often caused by mechanical motion, hydrodynamic impacts, and geological instability. These complex environmental factors can easily lead to material fatigue, structural deformation, seal failure, performance drift of electronic components, and even system malfunctions, severely impacting the working accuracy and service life of the directional drilling equipment.

[0003] Therefore, conducting high-temperature vibration tests to simulate extreme working conditions in actual deep-sea operations is of great significance for ensuring the reliable operation of directional drilling equipment. Through these tests, researchers can systematically study the dynamic response characteristics, performance evolution patterns, and failure mechanisms of equipment under combined high-temperature and vibration environments, identify design weaknesses and manufacturing defects, and clarify its adaptability boundaries in practical applications. The data obtained from these tests can not only provide a basis for optimizing and improving existing products but also provide direction and technical support for the development of next-generation high-performance directional drilling equipment, thereby promoting technological progress and innovation throughout the industry.

[0004] It is worth noting that due to significant differences in the structural dimensions of drilling rigs in practical applications, their lengths can range from several meters to tens of meters. Specimens of different lengths exhibit considerably different dynamic response characteristics under vibration excitation. Therefore, when conducting high-temperature vibration tests, it is essential to select an appropriate test method based on the specific structural form and dimensional characteristics of the specimen. For example, for shorter drilling rig components, a conventional single vibration table combined with a high-temperature environmental chamber can be used for testing; however, for ultra-long drilling rig systems, a dual-table parallel vibration test system is required. By coordinating the phase and amplitude of the two vibration tables, uniform excitation of the long specimen can be achieved, avoiding vibration transmission distortion and inconsistent response problems caused by excessive specimen length. This places higher demands on the coordinated operation and rapid switching between environmental simulation equipment and vibration tables.

[0005] However, current environmental simulation testing equipment on the market is mainly composed of standard and general-purpose environmental test chambers, with relatively simple structural forms and functional configurations. Most products are fixed structures, rigidly connected to the vibration table, resulting in inflexible functional modes. When testing requirements switch between "single environmental test," "single vibration test," and "environment-vibration composite test," it often requires cumbersome disassembly and reconfiguration of the equipment or lengthy waiting times, leading to a sequential process and low efficiency. This not only severely limits the ability to conduct different types of tests in parallel, resulting in a huge waste of time and space resources, but also introduces additional operational errors and sample damage risks due to multiple clamping operations. Furthermore, existing equipment still has limitations in terms of compatibility with multi-vibration table systems, making it difficult to efficiently and flexibly support various types of high-temperature vibration test scenarios. This technical bottleneck restricts the standardization and accuracy improvement of drilling equipment testing methods, further affecting the improvement of the independent research and development and quality assurance system for deep-sea high-end equipment.

[0006] In conclusion, developing an environmental simulation device that can flexibly adapt to various test modes and support efficient collaboration with vibration systems has become an urgent need for the development of testing technology for deep-sea oil and gas exploration equipment. Utility Model Content The purpose of this invention is to provide a multi-purpose integrated testing environment simulation chamber.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-purpose integrated testing environment simulation chamber is installed above at least one vibration test bench; the environment simulation chamber includes an insulated chamber for conducting environmental tests or vibration and environmental composite tests. During the combined vibration and environmental test, the insulated box is sealed on the surface of the vibration test bench to form a closed environmental simulation chamber. During the multi-vibration test and simultaneous vibration test, the table surfaces of each vibration test rig are aligned in a straight line along an X-axis; the length of the environmental simulation cavity is greater than the length of the specimen simultaneously positioned on the table surfaces of each vibration test rig. The environmental simulation chamber is movable along a Y-axis direction; during vibration testing and / or environmental testing only, the environmental simulation chamber is driven to move to one side of the Y-axis direction of each vibration test bench.

[0008] A further technical solution is that at least one partition is vertically installed in the environmental simulation chamber, which divides the environmental simulation chamber into multiple isolated sub-chambers.

[0009] A further technical solution is that the top of the environmental simulation chamber is provided with a specimen loading and unloading port, the length of which corresponds to the length of the specimen, and the specimen loading and unloading port is sealed by a sealing door panel.

[0010] A further technical solution also includes a specimen hoisting frame, which is suspended above the environmental simulation box; the specimen hoisting frame has multiple hoisting points arranged at intervals along the X-axis, which are used to hoist the specimen into the environmental simulation box through the specimen pick-up and drop-off port.

[0011] A further technical solution is that the bottom plate of the environmental simulation chamber has a circular clearance hole corresponding to the vibration test bench, or a detachable movable plate with a circular clearance hole is provided; the upper end of the vibration test bench is sealed and thermally insulated from the circular clearance hole of the environmental simulation chamber.

[0012] A further technical solution is that the bottom of the environmental simulation chamber is provided with a rectangular clearance hole, which is configured to have a length and the length direction corresponds to the length direction of the chamber body, so as to adapt to the combination requirements of different sub-chamber bottoms and different vibration test benches.

[0013] A further technical solution includes at least one sealing plate, which is spliced ​​and combined with the movable plate to jointly seal the rectangular clearance hole, thereby achieving the sealing of the environmental simulation box.

[0014] A further technical solution is that an equipment placement room is provided on one side of the insulated box, which is equipped with a refrigeration unit that provides low-temperature simulation for the environmental simulation chamber and a humidity device that provides humidity simulation.

[0015] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0016] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0017] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0018] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0019] The working principle and advantages of this utility model are as follows: This invention's environmental simulation chamber is designed to move along the Y-axis, enabling high system flexibility and efficiency. During combined vertical vibration and environmental tests, the chamber can be moved to the working position, sealing the vibration test bench surface to form a large, enclosed environmental simulation chamber. When only a single vertical vibration test or an independent environmental test is required, the chamber can be moved to one side. This design allows different types of tests to be performed in parallel or quickly switched, avoiding the waiting time and repeated disassembly and reassembly of equipment in traditional serial testing processes, thus significantly shortening the overall testing cycle and improving the utilization of time and space resources.

[0020] This invention provides a basis for simultaneously applying environmental simulation and multiple units coordinating vibration, which can realistically reproduce extreme working conditions such as the coupling of high temperature and vibration in the deep sea. It can discover potential failure modes that cannot be revealed by single stress testing, such as fatigue failure of materials under the combined action of thermal expansion and contraction and mechanical vibration.

[0021] The portable environmental simulation chamber allows for parallel environmental simulation and vibration testing, significantly saving time and space. It shortens the testing cycle, reduces labor and equipment costs, and minimizes errors and risks introduced by repeated clamping.

[0022] Through further technical solutions, this utility model can also bring about the following superior technical effects: 1) This utility model allows for the installation of partitions within the environmental simulation chamber, dividing the chamber into independent sub-chambers. This design enables: It can significantly improve testing efficiency, enabling the parallel execution of various environmental-vibration combination tests and greatly shortening the test cycle; it can optimize resources and energy consumption, sharing core environmental simulation systems (such as cooling / heating units) to reduce equipment costs and operating energy consumption; it can enhance space utilization, achieving "one box for multiple uses"; it can ensure the independence and precision of the test chamber, with independent control of environmental parameters in each sub-chamber to avoid mutual interference and ensure the purity of test conditions and the accuracy of results; it can improve system flexibility and scalability, with modular partition design that allows for easy adjustment of the number and layout of chambers according to needs, adapting to future changes in testing requirements.

[0023] 2) This utility model allows for the creation of a specimen loading / unloading port at the top of the environmental simulation chamber. A specimen lifting rack is then used to directly lower long specimens into the chamber from the top, ensuring a high level of airtightness when the loading / unloading port is closed. This design achieves the following: By utilizing vertical space, specimens are directly hoisted in from above, with a direct trajectory, simplifying the positioning and alignment process, making the operation faster and safer; the clamping process is modularized, allowing specimens to be positioned on the hoisting frame outside the chamber before being quickly hoisted into the environmental simulation chamber, shortening the test preparation cycle; the use of specialized hoisting equipment enables controllable and stable transfer and placement, significantly reducing the risk of specimen damage; The flexible design of the hoisting frame can easily accommodate specimens of different lengths. Precise vertical positioning helps ensure the consistency of the connection between the specimen and the vibration test bench, improving the accuracy of test results and the repeatability of the test.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0027] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0028] See appendix Figures 1-3 As shown, this embodiment discloses a multi-purpose integrated test environment simulation chamber 2, which is applied to an integrated test system. The system includes a horizontal base 1, the environment simulation chamber 2 set on the horizontal base 1, and two vibration test benches 3.

[0029] The operating modes of this test system include vibration test mode (vibration only), environmental test mode (environment only), and combined vibration and environmental test mode. Among them, the vibration test in the vibration test mode and the combined vibration and environmental test mode includes single-unit (vibration test bench 3) excitation vibration test and multi-unit (vibration test bench 3) parallel excitation vibration test (in this embodiment, it is a dual-unit test bench).

[0030] In the parallel vibration test, each vibration test bench 3 is set in a straight line along an X-axis.

[0031] In the combined vibration and environmental test mode, the environmental simulation chamber 2 is sealed on the table surface of the vibration test bench 3 to form a closed environmental simulation cavity 21; in the parallel vibration test of multiple benches, the length of the environmental simulation cavity 21 is greater than the length of the specimen 4 simultaneously positioned on the table surface of each vibration test bench 3.

[0032] The environmental simulation box 2 is movable along a Y-axis direction via guide rail 11 (or a ceiling rail). Figure 4 As shown, in the vibration test mode, the environmental simulation chamber 2 is moved to one side of the Y-axis direction of each of the vibration test benches 3. Figure 5 As shown, the environmental simulation chamber 2 can also be moved to one side of the Y-axis direction of each of the vibration test benches 3 in the environmental test mode, and the specimen 4 is positioned by the specimen hoisting frame 5. In the environmental test mode (environment only), the environmental simulation chamber 2 can also remain combined with the vibration test bench 3, using the vibration test bench as the platform for the specimen 4.

[0033] Preferred, such as Figures 6-8 As shown, the top of the environmental simulation chamber 2 has a specimen loading / unloading port 23, the length of which corresponds to the length of the specimen 4, and the specimen loading / unloading port 23 is sealed by a sealing door plate 24. The sealing door plates 24 are arranged in pairs, and a sealing element 25 (such as silicone rubber) is provided at the joint to ensure that the sealing door plate 24 effectively seals the specimen loading / unloading port 23 when closed, thereby ensuring the airtightness of the environmental simulation chamber 21.

[0034] Preferred, such as Figure 2 As shown, it also includes a specimen hoisting frame 5, which is suspended from the top of the environmental simulation chamber 2 and / or the vibration test bench 3. The specimen hoisting frame 5 has multiple hoisting points 51 arranged at intervals along the X-axis, which are used to hoist the specimen 4 into the environmental simulation chamber 2 via the specimen loading and unloading port 23 through the hoisting rope 52.

[0035] In test mode, the suspension rope 52 passes through the joint between the sealing door panels 24, such as... Figure 9 As shown, a seal is achieved by sealing element 25, thereby keeping the top of the environmental simulation chamber 2 sealed.

[0036] Preferred, such as Figure 10 , Figure 11 , Figure 15 As shown, a partition 22 is vertically installed in the environmental simulation chamber 2. By setting the horizontal position of the partition 22 within the environmental simulation chamber 2, the environmental simulation cavity 21 is divided into two isolated sub-chambers 211. Each sub-chamber 211 can be used for environmental simulation tests independently, or each sub-chamber 211 can be used for combined vibration and environmental tests independently. This "compartmental" design improves the utilization rate of the environmental simulation cavity 21 per unit time.

[0037] The bottom plate 26 of the environmental simulation chamber 2 has a circular clearance hole 27a corresponding to the vibration test bench 3, or it has a detachable movable plate 29 with a circular clearance hole 27a. The upper end of the vibration test bench 3 is sealed and thermally insulated with the circular clearance hole 27a of the environmental simulation chamber 2.

[0038] The movable plate 29 is made of a pressure-bearing plate with an insulation layer, possessing heat insulation, pressure resistance, and load-bearing capacity. The diameter of the circular clearance hole 27a can be flexibly configured according to requirements. Figure 12 The diagram shown is a schematic of the movable plate 29.

[0039] The bottom of the environmental simulation chamber 2 is provided with a rectangular clearance hole 27b. The rectangular clearance hole 27b is configured to have a length, and the length direction corresponds to the length direction of the chamber body, so as to adapt to the combination requirements of the bottom of different sub-chambers 211 and different vibration test benches 3. More importantly, the rectangular clearance hole 27b can realize the specimen clamping and positioning requirements after the vibration test bench 3 is moved horizontally on one side.

[0040] like Figure 13 As shown, it also includes at least one sealing plate 28, which is spliced ​​and combined with the movable plate 29 to jointly seal the rectangular clearance hole 27b, so as to achieve the sealing of the environmental simulation box 2.

[0041] Preferred, such as Figure 18 As shown, at least one of the vibration test benches 3 is driven and its position is adjustable along the X-axis. This design is intended to accommodate the requirements of parallel vibration tests on specimens 4 of different lengths.

[0042] In implementation, the movable vibration test bench 3 is positioned corresponding to the rectangular clearance hole 27b. After each adjustment of the horizontal position of the vibration test bench in the X-axis direction, the movable plate 29 is moved within the rectangular clearance hole 27b, allowing the thermal insulation support assembly 6 on the vibration test bench 3 to align vertically with the circular clearance hole 27a of the movable plate 29. Simultaneously, one or more sealing plates 28 seal the rectangular clearance hole 27b. This design enables the test chamber to have flexible compatibility when clamping specimens of different lengths for parallel vibration testing, thereby effectively improving the system's versatility.

[0043] Preferably, a heating device (such as a heating wire) can be directly installed inside the environmental simulation chamber 2 of the present invention. Since the heating device is relatively conventional and its placement is not particularly important, it is not shown in the diagram of the chamber. Furthermore, in addition to high-temperature testing, the environmental tests of this invention can also simulate low-temperature, humidity, and other environmental tests by setting up other corresponding equipment; therefore, this invention is not limited to the type of environmental test. Figure 16 , Figure 17 As shown, in this embodiment, an equipment placement room 7 is provided on one side of the insulated box 20. The equipment placement room 7 is equipped with a refrigeration unit 71 and a humidity device 72, thereby providing low temperature simulation or humidity simulation for the environmental simulation chamber 21 inside the insulated box 20.

[0044] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
