Description

Technical Field

[0001] This utility model relates to the field of wind resistance testing technology, specifically to a container house wind resistance static load test device. Background Technology

[0002] This equipment is used to simulate the impact of strong winds on container houses and evaluate their wind uplift resistance. It mainly consists of a loading system, a pressure simulation device, a data acquisition unit, and a house fixing mechanism. By adjusting the pressure difference to simulate static loads under different wind speeds, it precisely controls the loading force value and distribution, and simultaneously collects data on the displacement, stress, and force on the connection points of the house structure. The test process can simulate extreme wind environments such as typhoons, covering various working conditions, providing a scientific basis for container house structural optimization, material selection, and safety certification. It is suitable for building testing institutions and related manufacturing enterprises.

[0003] According to a published paper (Publication No.: CN220872036U), a pseudo-static load testing device for wind uplift resistance of container houses includes: a first specimen, a second specimen, a reinforcement device, and a testing device. The first specimen is a house panel without the reinforcement device. The second specimen is a house panel with the reinforcement device installed, which is placed at key joints of the second specimen to reinforce it. The testing device includes a displacement sensor and a strain gauge. The displacement sensor is used to detect the displacement of the first and second specimens, and the strain gauge is used to detect the strain of the first and second specimens. The purpose of this application is to quantify the degree of damage to the structural system and the reinforcement components, thereby enabling more accurate and reasonable verification of the reinforcement effect of the container house roof.

[0004] In the aforementioned application, the cooperation between components such as the first and second test pieces makes it difficult to address the multi-directional wind exposure function when testing container houses in wind, resulting in incomplete data obtained during the testing process. Therefore, we propose a quasi-static load testing device for the wind resistance of container houses. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a container house wind uplift pseudo-static load test device, which solves the technical problem of incomplete data obtained during the test process in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a container house wind-shearing pseudo-static load testing device, comprising: a base plate, a column fixedly connected to the top of the base plate, a stress sensing device fixedly connected to the top of the base plate, a container body fixedly connected to the top of the stress sensing device, a data collection cabinet fixedly connected to the top of the base plate, and a wind blowing mechanism provided on the side of the column.

[0007] The air blowing mechanism includes a motor, the side of which is fixedly connected to the side of the column. A threaded rod is fixedly connected to the end of the motor output shaft. A bevel gear is fixedly connected to one end of the threaded rod. A threaded rod is rotatably connected to the side of the column. A bevel gear is fixedly connected to one end of the threaded rod. The bevel gears mesh with each other. A baffle is engaged on the inner side of the column. Threaded sleeves are threadedly connected to the circumferential surfaces of both the threaded rod and the threaded rod. An air blower is fixedly connected to the circumferential surface of the threaded sleeve. The side of the air blower is slidably connected to the side of the baffle.

[0008] For example, in at least one embodiment of this utility model, a container house wind-resistant static load testing device is provided, which further includes: a number of columns that are symmetrically arranged along the vertical central axis of the base plate to provide balanced and stable support for the wind blowing mechanism and the cleaning mechanism, avoiding excessive force on one side that could cause the equipment to tilt or deform, ensuring the overall structural stability and the safety of the test process; and a number of stress sensing devices that are symmetrically arranged along the vertical central axis of the container body to accurately collect stress data of the container body under wind force from multiple symmetrical points, reducing single-point measurement errors, making the data more representative, and improving the accuracy and reliability of the test results.

[0009] The column has a slot on its side, and the baffle is fixedly connected to a block on its side. The width of the block is equal to the width of the slot, which enables a stable connection between the baffle and the column, ensuring the ease of baffle installation, facilitating disassembly and maintenance, and improving the stability of the test equipment and the reliability of the test data.

[0010] The side of the baffle is provided with a sliding groove, and the side of the blower is fixedly connected with a slider. The width of the slider is equal to the width of the sliding groove, which provides stable lateral support and guidance for the blower, ensuring that the blower moves stably along the preset path, thereby ensuring the accuracy of the simulated wind force application position.

[0011] The bevel gear 1 and bevel gear 2 have spoke holes on their sides. The number of spoke holes is set to a certain number and arranged in a circumferential array on the sides of bevel gear 1 and bevel gear 2. While ensuring the structural strength of the bevel gears, the weight of the gears is reduced, the rotational inertia is reduced, and the motor load is reduced. The number of teeth of bevel gear 1 is equal to the number of teeth of bevel gear 2, which can realize constant speed transmission, ensure that threaded rod 1 and threaded rod 2 rotate synchronously, make the movement speed of the blowers on both sides consistent, ensure symmetrical and balanced wind force, and improve the stability of the test.

[0012] According to another aspect, at least one embodiment of the present invention also provides a container house wind uplift pseudo-static load testing device, comprising: a cleaning mechanism provided on the side of the column, the cleaning mechanism including a top plate, the bottom of the top plate being fixedly connected to the top of the column, a rotating shaft being fixedly connected to the end of the threaded rod away from the bevel gear, the rotating shaft rotatably passing through the inner side of the column, a half gear being fixedly connected to one end of the rotating shaft, an L-shaped plate being slidably connected to the inner side of the top plate, a rack being fixedly connected to the side of the L-shaped plate, the half gear meshing with the rack, a spring being fixedly connected to the side of the rack, and a cleaning plate being fixedly connected to the side of the rack.

[0013] For example, in at least one embodiment of the present invention, a container house wind-shearing pseudo-static load testing device is provided, which further includes: a number of springs are arranged in a linear array on the side of the L-shaped plate, one end of the spring is located on the displacement trajectory of the L-shaped plate, which can provide uniform reset force, ensure that the cleaning plate and cleaning brush assembly are subjected to balanced force in reciprocating motion, avoid the cleaning mechanism from jamming or deviating due to uneven reset force, and ensure stable and efficient cleaning action.

[0014] A cleaning brush assembly is fixedly connected to the bottom of the cleaning plate. Several cleaning brush assemblies are arranged in a linear array at the bottom of the cleaning plate. The multiple cleaning brush assemblies are arranged in a linear array to fully cover the area to be cleaned on the top of the container, avoiding cleaning dead spots caused by the limited coverage of a single cleaning brush assembly.

[0015] The top of the container is located on the displacement trajectory of the cleaning brush group, which can effectively remove dust, debris, residual particles, etc. from the top, and avoid these substances from affecting the uniformity of wind force in subsequent wind resistance tests. The sides of the container are located on the displacement trajectory of the blower, which can ensure that the wind force range completely covers the test area on the side of the container and avoid test blind spots.

[0016] The bottom of the top plate is provided with a slide rail, and the number of slide rails is set to a certain number and arranged in a linear array at the bottom of the top plate. The top of the cleaning plate is fixedly connected with a slide bar, the width of which is equal to the width of the slide rail, forming a tightly fitted sliding structure. This strictly limits the movement trajectory of the cleaning plate and ensures that the cleaning brush group always acts on the top of the container body along a preset linear path, preventing cleaning dead corners due to path deviation and ensuring the comprehensiveness of the cleaning range.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] In this invention, the threaded rods, blower, and bevel gears within the air-blowing mechanism work together. Driven by a motor, the bevel gears cause the threaded rods one and two to rotate, moving the blower on the threaded sleeve. With the aid of a baffle guide, multi-angle, wide-range airflow is achieved. This can simulate different wind forces and their positions, comprehensively testing the wind resistance of containers. The symmetrical and stable structure ensures experimental accuracy and provides reliable data support for the wind-resistant design of container houses.

[0019] In this invention, the rotating shaft, half-gear, and cleaning plate within the cleaning mechanism work together. The rotation of the threaded rod drives the rotating shaft and half-gear to rotate. Under the meshing action of the half-gear and rack, and with the spring resetting, the cleaning plate and bottom cleaning brush assembly reciprocate. Combined with the guide rails and sliders, this efficiently cleans debris from the top of the container. This prevents debris from affecting the accuracy of wind resistance testing. Furthermore, the wind-blowing mechanism eliminates the need for an additional power source, saving energy and improving the overall practicality and testing accuracy of the equipment.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

They are used only for the convenience of description and simplification of operation, and are not intended to 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, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates a container house wind-shearing pseudo-static load testing device according to an embodiment of the present invention, including: a base plate 1, a column 2 fixedly connected to the top of the base plate 1, a stress sensing device 3 fixedly connected to the top of the base plate 1, a container body 4 fixedly connected to the top of the stress sensing device 3, a data collection cabinet 5 fixedly connected to the top of the base plate 1, and a wind blowing mechanism 6 provided on the side of the column 2.

[0034] The air blowing mechanism 6 includes a motor 61, the side of which is fixedly connected to the side of the column 2. The end of the output shaft of the motor 61 is fixedly connected to a threaded rod 62, one end of which is fixedly connected to a bevel gear 63. The side of the column 2 is rotatably connected to a threaded rod 64, one end of which is fixedly connected to a bevel gear 65. The bevel gear 63 and the bevel gear 65 mesh with each other. A baffle 66 is snapped onto the inner side of the column 2. Threaded sleeves 67 are threadedly connected to the circumferential surfaces of both the threaded rod 62 and the threaded rod 64. An air blower 68 is fixedly connected to the circumferential surface of the threaded sleeve 67. The side of the air blower 68 is slidably connected to the side of the baffle 66.

[0035] In some examples, the number of columns 2 is set to be several and symmetrical to each other along the vertical central axis of the base plate 1, providing balanced and stable support for the wind blowing mechanism 6 and the cleaning mechanism 7, avoiding excessive force on one side that could cause the equipment to tilt or deform, ensuring the overall structural stability and the safety of the test process. The number of stress sensing devices 3 is set to be several and symmetrical to each other along the vertical central axis of the container body 4, accurately collecting stress data of the container body 4 under wind force from multiple symmetrical points, reducing single-point measurement errors, making the data more representative, and improving the accuracy and reliability of the test results.

[0036] The side of the column 2 is provided with a slot, and the side of the baffle 66 is fixedly connected with a locking block 69. The width of the locking block 69 is equal to the width of the slot, so as to realize the stable connection between the baffle 66 and the column 2, ensuring the ease of installation of the baffle 66, facilitating disassembly and maintenance in the future, and improving the stability of the test equipment operation and the reliability of the test data.

[0037] The side of the baffle 66 is provided with a sliding groove, and the side of the blower 68 is fixedly connected with a slider 610. The width of the slider 610 is equal to the width of the sliding groove, which provides stable lateral support and guidance for the blower 68, ensuring that the blower 68 moves stably along the preset path, thereby ensuring the accuracy of the simulated wind force action position.

[0038] The sides of bevel gear 63 and bevel gear 65 are provided with spoke holes. The number of spoke holes is set to a certain extent and is arranged in a circumferential array on the sides of bevel gear 63 and bevel gear 65. While ensuring the structural strength of the bevel gears, the weight of the gears is reduced, the rotational inertia is reduced, and the load on the motor 61 is reduced. The number of teeth of bevel gear 63 is equal to the number of teeth of bevel gear 65, which can realize constant speed transmission, ensure that threaded rod 62 and threaded rod 64 rotate synchronously, and make the movement speed of the blowers 68 on both sides consistent, ensuring symmetrical and balanced wind force and improving the stability of the test.

[0039] For example, such as Figures 1-5 As shown, the operator starts motor 61, whose output shaft drives threaded rod 62 to rotate. Threaded rod 62, through bevel gears 63 and 65, drives threaded rod 64 to rotate synchronously. Since both threaded rods 62 and 64 are threadedly connected to threaded sleeves 67 on their circumferences, and the blower 68 on the side of the threaded sleeve 67 is slidably connected to the groove of baffle 66 via slider 610, the threaded sleeve 67, as it rotates with the threaded rod, drives the blower to move stably along baffle 66. During this process, the symmetrically distributed columns 2 provide stable support for the overall structure, allowing the blower 68 to blow airflow onto the side of the container body 4 at different heights and positions, simulating different wind force scenarios. The stress sensing device 3, in conjunction with the stress sensing device, transmits the test data to the data collection cabinet 5, completing the wind resistance performance test.

[0040] like Figures 1-5As shown, this invention illustrates a container house wind uplift pseudo-static load testing device according to another embodiment of the present invention, comprising: a cleaning mechanism 7 provided on the side of the column 2, the cleaning mechanism 7 including a top plate 71, the bottom of the top plate 71 being fixedly connected to the top of the column 2, a rotating shaft 72 being fixedly connected to one end of the threaded rod 64 away from the bevel gear 65, the rotating shaft 72 rotatably passing through the inner side of the column 2, a half gear 73 being fixedly connected to one end of the rotating shaft 72, an L-shaped plate 74 being slidably connected to the inner side of the top plate 71, a rack 75 being fixedly connected to the side of the L-shaped plate 74, the half gear 73 and the rack 75 meshing with each other, a spring 76 being fixedly connected to the side of the rack 75, and a cleaning plate 77 being fixedly connected to the side of the rack 75.

[0041] In some examples, the number of springs 76 is set to several, which are arranged in a linear array on the side of the L-shaped plate 74. One end of the spring 76 is located on the displacement trajectory of the L-shaped plate 74, which can provide uniform reset force to ensure that the cleaning plate 77 and the cleaning brush assembly 78 are subjected to balanced force in reciprocating motion, avoid the cleaning mechanism 7 from jamming or shifting due to uneven reset force, and ensure stable and efficient cleaning action.

[0042] A cleaning brush set 78 is fixedly connected to the bottom of the cleaning plate 77. The number of cleaning brush sets 78 is set to several and arranged in a linear array at the bottom of the cleaning plate 77. The multiple cleaning brush sets 78 are arranged in a linear array, which can fully cover the area to be cleaned on the top of the container body 4, avoiding cleaning dead corners due to the limited coverage of a single cleaning brush set 78.

[0043] The top of the container body 4 is located on the displacement trajectory of the cleaning brush group 78, which can effectively remove dust, debris, residual particles, etc. from the top, and avoid these substances from affecting the uniformity of wind force in subsequent wind resistance tests. The sides of the container body 4 are located on the displacement trajectory of the blower 68, which can ensure that the wind force range completely covers the test area on the side of the container body 4, and avoid test blind spots.

[0044] The bottom of the top plate 71 is provided with a slide rail. Several slide rails are arranged in a linear array at the bottom of the top plate 71. The top of the cleaning plate 77 is fixedly connected with a slide bar 79. The width of the slide bar 79 is equal to the width of the slide rail, forming a tightly fitted sliding structure. This strictly limits the movement trajectory of the cleaning plate 77, ensuring that the cleaning brush assembly 78 always acts on the top of the container body 4 along a preset linear path, preventing cleaning dead corners due to path deviation, and ensuring the comprehensiveness of the cleaning range.

[0045] For example, such as Figures 1-5As shown, the rotation of the threaded rod 64 drives the rotating shaft 72 and the half gear 73 to rotate. The half gear 73 meshes with the rack 75 on the L-shaped plate 74, pushing the L-shaped plate 74 to move. At the same time, the spring 76 is compressed. When the half gear 73 rotates to the toothless part, the spring 76 returns to its original position and pulls the L-shaped plate 74 back. This causes the cleaning plate 77 and the bottom cleaning brush assembly 78 to reciprocate along the slide rail at the bottom of the top plate 71 with the slide bar 79, thereby continuously cleaning the top of the container body 4 and removing debris to ensure the accuracy of the test.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
