Description

Technical Field

[0001] This utility model relates to the field of cleanroom equipment testing technology, specifically, to a testing device. Background Technology

[0002] In some cleanrooms or operating rooms, pass-through windows are often used as a medium for transferring items. The two sides of the pass-through window are usually of different cleanliness levels. Doors are installed on both sides of the pass-through window to isolate it from the outside space. High-efficiency filters, ultraviolet lamps, and other devices are installed on the upper or side of the interior of the pass-through window to disinfect the interior space.

[0003] In daily use, the wind speed and airflow pattern of the pass-through window need to be tested periodically. The pass-through window has an interlocking structure; the fan can only operate when both doors are closed by default, and testing can only be performed while the fan is running. During testing, the tester enters the pass-through window holding an anemometer, a water mist generator duct (or a dry ice container), etc., and must open one door of the pass-through window. To maintain the fan's operation, the tester must continuously press the door-closing sensor switch of the pass-through window; the fan will only operate normally when the pass-through window recognizes the door is closed, making the operation quite difficult for the tester. Furthermore, because one door of the pass-through window is open, the pressure on the open side is relatively low. When testing with a handheld anemometer, the airflow inside the pass-through window during testing differs from the actual operating airflow (when both doors are closed). At test points near the open side of the pass-through window, some air flows from the inside to the low-pressure side (the open side), resulting in inaccurate wind speed test results. When testing airflow patterns using a handheld water mist generator duct (or a handheld dry ice container), the air flows from the inside to the low-pressure side (the open side), causing a shift in the airflow pattern and failing to reflect the actual airflow state inside the transfer window during operation. Furthermore, when testing with a handheld anemometer, water mist generator duct (or handheld dry ice container), it is difficult to ensure consistent horizontal levels at all test points, resulting in significant testing errors. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a testing device is provided for testing the performance of a transfer window.

[0005] The testing device includes a base, a telescopic component, and a support component. The telescopic component is telescopically connected to the base, and the support component is provided at the end of the telescopic component away from the base. The support component includes a first mounting part and a second mounting part, one of which is used to mount the test element and the other is used to mount the distance measuring element.

[0006] The testing device provided in this application allows for direct movement of the testing device within a transfer window when testing wind speed or other performance at different locations at the same horizontal height. The telescopic components and base ensure consistent height of the test element at different positions, resulting in more accurate test results and a simpler, more convenient testing process. One of the first and second mounting sections houses the distance measuring device, while the other houses the test element, enabling precise acquisition of the test element's position information. Adjusting the telescopic components and base allows for more precise control of the distance between the test element and structural components such as HEPA filters, ensuring this distance remains within a suitable range. When testing transfer windows of different sizes, the telescopic components and base can be adjusted for adaptation. In use, compared to operators holding devices such as velocimeters, the testing device provided in this application can be entirely contained within the transfer window, and the doors on both sides of the transfer window can be completely closed, avoiding the impact of incomplete door closure on wind speed and airflow patterns, further improving the accuracy of the test results.

[0007] For example, a rotating assembly is provided between the support member and the telescopic member. The rotating assembly is connected to the support member and drives the support member to rotate relative to the telescopic member. In this way, when the HEPA filter is installed in different positions of the transfer window, it can be adapted by rotating the support member, which is a simple and convenient process.

[0008] For example, the rotation angle of the support member relative to the telescopic member is 0 to 90°.

[0009] For example, the rotating assembly includes a fixing member connected to the telescopic member, a rotating member rotatably connected to the fixing member, and a first fastener for fastening the rotating member. The support member is connected to the rotating member, and the rotating member has a connecting hole. The first fastener passes through the fixing member into the connecting hole to fix the rotating member.

[0010] For example, the first mounting portion includes a first mounting surface and first clamping members located at opposite ends of the first mounting surface; and / or the second mounting portion includes a second mounting surface and second clamping members located at opposite ends of the second mounting surface.

[0011] For example, the ranging element is installed in the first mounting part, and the support member is rotatable between the first station and the second station. When the support member is in the first station, the ranging end of the ranging element faces the top direction of the testing device, and when the support member is in the second station, the ranging end of the ranging element faces the side direction of the testing device.

[0012] For example, at least one of the first clamping members is connected to a first elastic member and is movable relative to a first mounting surface, the first elastic member applying a force toward the first clamping member towards the opposite side; and / or, at least one of the second clamping members is connected to a second elastic member and is movable relative to a second mounting surface, the second elastic member applying a force toward the second clamping member towards the opposite side.

[0013] For example, the base includes a seat and a sleeve connected to the seat, a telescopic member passes through the sleeve, and a second fastener passes through the side wall of the sleeve and abuts against the telescopic member to fix the telescopic member.

[0014] For example, the support includes a support rod, a first mounting portion and a second mounting portion are respectively connected to the support rod, and the first mounting portion and / or the second mounting portion are threadedly connected, plugged in or rotatably connected to the support rod.

[0015] For example, the support member is threadedly connected to the telescopic member, or...

[0016] The support and telescopic components are plugged in, or,

[0017] One of the support member and the telescopic member has a spherical structure at one end and the other has a limiting groove adapted to the spherical structure at one end. The spherical structure is rotatably installed in the limiting groove.

[0018] For example, the test element includes a velocity measuring element and / or a mist generating element.

[0019] For example, the first mounting part and the second mounting part are located on the same horizontal plane.

Detailed Implementation

[0031] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0032] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0033] This invention provides a testing device. This testing device can be used to test the performance of a pass-through window. Specifically, the testing device can be used to test parameters such as wind speed and airflow pattern of the pass-through window. (Refer to reference...) Figure 1 , Figure 2 , Figure 4 and Figure 5The testing device 10 may include a base 110, a telescopic member 120, and a support member 130. The telescopic member 120 is telescopically connected to the base 110. Specifically, the telescopic member 120 is vertically telescopic relative to the base 110. A support member 130 may be provided at the end of the telescopic member 120 away from the base 110. The support member 130 may include a first mounting portion 1310 and a second mounting portion 1320. One of the first mounting portion 1310 and the second mounting portion 1320 can be used to mount a test element, and the other can be used to mount a distance measuring element. The first mounting portion 1310 and the second mounting portion 1320 can be arbitrarily configured according to usage requirements. The first mounting portion 1310 and the second mounting portion 1320 may be located at opposite ends of the support member 130. The support member 130 can fix the relative position between the test element and the distance measuring element. The distance measuring element can obtain the position information of the test element. When the telescopic component 120 extends or retracts relative to the base 110, it causes the support component 130 and the test element and distance measuring component on the support component 130 to move together.

[0034] The testing device 10 can be used as follows: install the ranging component on the first mounting part 1310 and the testing element on the second mounting part 1320 (or install the testing element on the first mounting part 1310 and the ranging component on the second mounting part 1320), open the door of the transfer window, place the testing device 10 inside the transfer window, turn on the ranging component and the testing element (when the testing element is a speed measuring component, this operation is to turn on the speed measuring component; when the testing element is a mist generating component 150, this operation is to place dry ice or any other mist-generating substance inside the mist generating component 150 or turn on the switch of the water mist generator, etc.), adjust the telescopic component 120 to the predetermined position (for example, the distance displayed by the ranging component is 15cm to 30cm from the HEPA filter), close the door of the transfer window, turn on the air shower of the transfer window, and record the corresponding test results (when the testing element is a speed measuring component, this operation is to record the wind speed value; when the testing element is a mist generating component, this operation is to record the airflow pattern).

[0035] When testing wind speed or other performance at different locations at the same horizontal height, the testing device 10 can be moved directly to different positions within the transfer window. The telescopic component 120 and the base 110 ensure the consistency of the height of the test element at different positions, resulting in more accurate test results and a simpler and more convenient testing process. One of the first mounting part 1310 and the second mounting part 1320 is equipped with a distance measuring component, and the other with the test element, allowing for precise acquisition of the test element's position information. By adjusting the telescopic component 120 and the base 110, the distance between the test element and structural components such as the HEPA filter can be more precisely controlled and kept within a suitable range. When testing transfer windows of different sizes, the telescopic component 120 and the base 110 can be adjusted for adaptation. In use, compared to operators holding speed measuring devices, the testing device 10 provided in this application can be entirely placed within the transfer window, and the doors on both sides of the transfer window can be completely closed, avoiding the impact of incomplete door closure on wind speed and airflow pattern, further improving the accuracy of the test results.

[0036] For example, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A rotating assembly 140 can be provided between the telescopic member 120 and the support member 130. The rotating assembly 140 can be connected to the support member 130 and drive the support member 130 to rotate relative to the telescopic member 120. That is, the ranging element and the test element can rotate together. In this way, the ranging element can measure the distance between the test element and the device (e.g., HEPA filter) in the transfer window in different directions, which facilitates the measurement of data corresponding to different distances. The data measured by the test device 10 can be more comprehensive. The setting of the rotating assembly 140 makes the rotation process of the test element and the ranging element simpler and faster. When the HEPA filter is installed in different positions in the transfer window, the support member 130 can be rotated by the rotating assembly 140 for adaptation, which is simple and convenient.

[0037] For example, in conjunction with reference Figure 2 , Figure 3 , Figure 5 and Figure 6 The rotation angle of the support member 130 relative to the telescopic member 120 can be 0° to 90°. Figure 2 and Figure 3 The rotation angle of the middle support member 130 relative to the telescopic member 120 is 0. Figure 5 and Figure 6 The rotation angle of the middle support member 130 relative to the telescopic member 120 is 90°. The ranging member can rotate between 0° and 90°, and can measure the position data of the test element in different directions (e.g., vertical and horizontal directions) without changing the position of the test device 10 itself.

[0038] For example, in conjunction with reference Figure 1 , Figure 3 , Figure 4 and Figure 6 The rotating assembly 140 may include a fixing member 1410 connected to the telescopic member 120, a rotating member 1420 rotatably connected to the fixing member 1410, and a first fastener 1430 for securing the rotating member 1420. A support member 130 may be connected to the rotating member 1420. The rotating member 1420 has a connecting hole, and the first fastener 1430 can pass through the fixing member 1410 into the connecting hole to secure the rotating member 1420. An elastic pad may be provided on the side of the rotating member 1420 that contacts the fixing member 1410. The elastic pad provides anti-slip properties and improves the stability of the rotating member 1420. For example, the fixing member 1410 may have an opening. In use, the rotating component 1420 is rotated to a predetermined angle. After rotation, the first fastener 1430 passes through the opening of the fixing component 1410 and is inserted into the connecting hole. By tightening the first fastener 1430, the position of the rotating component 1420 relative to the fixing component 1410 is fixed, thus ensuring the stability of the position of the ranging component and the ranging element in different orientations and ensuring the stability of the testing process. For example, the rotating component 1420 may have a first limiting surface and a second limiting surface, and the fixing component 1410 may have a third limiting surface and a fourth limiting surface. When the rotation angle of the support component 130 relative to the telescopic component 120 is 0°, the first limiting surface and the third limiting surface abut against each other, and the second limiting surface and the fourth limiting surface are spaced apart. When the rotation angle of the support component 130 relative to the telescopic component 120 is 90°, the second limiting surface and the fourth limiting surface abut against each other, and the first limiting surface and the third limiting surface are spaced apart.

[0039] For example, in conjunction with reference Figure 1 and Figure 2 The first mounting portion 1310 may include a first mounting surface 1311 and first clamping members 1312 located at opposite ends of the first mounting surface 1311. The test element or ranging member mounted in the first mounting portion 1310 is abutted and fixed against the first mounting surface 1311 and clamped and fixed between the two first clamping members 1312, simplifying the clamping and installation process and improving stability. And / or, the second mounting portion 1320 includes a second mounting surface 1321 and second clamping members 1322 located at opposite ends of the second mounting surface 1321. The test element or ranging member mounted in the second mounting portion 1320 is abutted and fixed against the second mounting surface 1321 and clamped and fixed between the two second clamping members 1322, simplifying the clamping and installation process and improving stability.

[0040] For example, in conjunction with reference Figure 1 and Figure 2The ranging element is installed within the first mounting portion 1310. The support member 130 is rotatable between the first and second stations. When the support member 130 is in the first station, the ranging end of the ranging element faces the top of the testing device 10, i.e., towards the top surface of the transfer window. For example, when the support member 130 is in the first station, the first mounting surface 1311 can face the side of the testing device 10. Typically, the ranging end of a ranging element is located on its side. In this case, the ranging end of the ranging element installed in the first mounting portion can face the top, thus obtaining the vertical position information of the test element. When the HEPA filter is installed at the top of the transfer window, the distance between the test element and the top HEPA filter is obtained. This arrangement makes it easier to obtain the vertical position information of the test element, making the process convenient and efficient.

[0041] In use, rotate the support 130 to the first position, insert the first fastener 1430 into the connecting hole of the rotating part 1420, tighten the first fastener 1430 to fix the rotating part 1420 and the support 130, install the ranging part on the first mounting part 1310 and clamp it, and install the test element on the second mounting part 1320 and clamp it.

[0042] Taking an embodiment where the test element is a velocity measuring device as an example, the testing process can be as follows: Open the door of the transfer window, place the test device 10 inside the transfer window, turn on the distance measuring device and the velocity measuring device, adjust the telescopic component 120 to a predetermined position (for example, the velocity measuring device is 15cm to 30cm away from the top high-efficiency filter), tighten the second fastener 1130 to fix the telescopic component 120, close the door of the transfer window, turn on the air shower of the transfer window, and record the wind speed value. Taking an embodiment where the test element is a mist generating device 150 as an example, the testing process can be as follows: Open the door of the transfer window, place the test device 10 inside the transfer window, turn on the distance measuring device, adjust the telescopic component 120 to a predetermined position (for example, the mist generating device 150 is 15cm to 30cm away from the top high-efficiency filter), tighten the second fastener 1130 to fix the telescopic component 120, place dry ice (or any other mist-generating substance) inside the mist generating device 150, close the door of the transfer window, turn on the air shower of the transfer window, and record the airflow pattern.

[0043] For example, in conjunction with reference Figure 4 and Figure 5When the support member 130 is in the second position, the measuring end can face the side of the testing device, i.e., the side of the transfer window. At this time, the first mounting surface 1311 can face the bottom of the testing device 10, and the measuring end of the measuring member installed in the first mounting part 1310 faces sideways, thus obtaining the horizontal position information of the test element. When the high-efficiency filter is installed on the side of the transfer window, the distance between the test element and the side high-efficiency filter is obtained. This arrangement makes it easier to obtain the horizontal position information of the test element, making the process convenient and efficient.

[0044] In use, rotate the support 130 to the second position, insert the first fastener 1430 into the connecting hole of the rotating part 1420, tighten the first fastener 1430 to fix the rotating part 1420 and the support 130, install the ranging part on the first mounting part 1310 and clamp it, and install the test element on the second mounting part 1320 and clamp it.

[0045] Taking an embodiment where the test element is a velocity measuring device as an example, the testing process can be as follows: Open the door of the transfer window, place the test device 10 inside the transfer window, turn on the distance measuring device and the velocity measuring device, adjust the base 110 to a predetermined position (for example, the velocity measuring device is 15cm to 30cm away from the side HEPA filter), tighten the second fastener 1130 to fix the telescopic member 120, close the door of the transfer window, turn on the air shower of the transfer window, and record the wind speed value. Taking an embodiment where the test element is a mist generating device 150 as an example, the testing process can be as follows: Open the door of the transfer window, place the test device 10 inside the transfer window, turn on the distance measuring device, adjust the telescopic member 120 to a predetermined position (for example, the mist generating device 150 is 15cm to 30cm away from the side HEPA filter), tighten the second fastener 1130 to fix the telescopic member 120, place dry ice (or any other mist-generating substance) inside the mist generating device 150, close the door of the transfer window, turn on the air shower of the transfer window, and record the airflow pattern.

[0046] For example, in conjunction with reference Figure 1 and Figure 7At least one of the first clamping members 1312 may be connected to a first elastic member 1313 and movable relative to the first mounting surface 1311. The first elastic member 1313 can apply a force to the first clamping member 1312 toward the opposite side of the first clamping member 1312. This allows the rangefinder to be better clamped within the two first clamping members 1312, resulting in more stable clamping and ensuring the stability of the testing process. Exemplarily, at least one of the second clamping members 1322 may be connected to a second elastic member and movable relative to the second mounting surface 1321. The second elastic member can apply a force to the second clamping member 1322 toward the opposite side of the second clamping member 1322. This allows the test element to be better clamped within the two second clamping members 1322, resulting in more stable clamping and ensuring the stability of the testing process. Exemplarily, each first clamping member 1312 and its corresponding first clamping member 1312, as well as the first mounting surface 1311 between them, can be a group. The first mounting portion 1310 can be configured with multiple groups depending on the size of the rangefinder to be mounted. For example, the first mounting portion 1310 may include two sets. Similarly, each second clamping member 1322 and its corresponding second clamping member 1322 and the second mounting surface 1321 between them may be a set, and the second mounting portion 1320 may include three sets. The inner side of the first clamping member 1312 and / or the second clamping member 1322 may be provided with an anti-slip pad to ensure clamping stability.

[0047] For example, the test element may include a velocity measuring element and / or a mist generating element. The velocity measuring element can measure the wind speed at the test point. The mist generating element can generate mist to observe and measure the airflow pattern of the transfer window. Depending on the testing requirements of the transfer window, the test element may also be other testing instruments, which are not limited here.

[0048] For example, in conjunction with reference Figure 1 and Figure 8 The mist-generating component 150 may include a housing 1510 and a cover 1520 fastened to the housing 1510. A housing space for placing dry ice is formed between the housing 1510 and the cover 1520. The cover 1520 and / or the housing 1510 may be provided with a through hole 1530 communicating with the housing space. Dry ice is placed in the housing space. After the mist-generating component 150 is installed in the second mounting part 1320, the airflow pattern of the transfer window is tested using mist. The housing space better ensures the placement of the dry ice and allows the generated mist to flow out through the through hole 1530 to test the airflow pattern of the transfer window. Of course, those skilled in the art will understand that the mist-generating component can also be other devices capable of generating mist, such as a water mist generator, as long as it can generate mist; no limitation is made here.

[0049] For example, in conjunction with reference Figure 1 , Figure 2 , Figure 4 and Figure 5The base 110 may include a seat body 1110 and a sleeve 1120 connected to the seat body 1110. A telescopic member 120 may pass through the sleeve 1120. A second fastener 1130 passes through the side wall of the sleeve 1120 and abuts against the telescopic member 120 to fix it in place. After the telescopic member 120 is adjusted to a predetermined position, the position of the telescopic member 120 relative to the sleeve 1120 can be stabilized by tightening the second fastener 1130, thus ensuring the stability of the positions of the ranging element and the testing element.

[0050] For example, in conjunction with reference Figure 1 and Figure 4 The telescopic component 120 is a prism, and a limiting groove adapted to the prism is formed inside the sleeve 1120. This makes the horizontal position of the telescopic component 120 more fixed within the sleeve 1120, preventing wobbling and thus ensuring the stability of the position of the ranging component and the testing element. For example, the telescopic component 120 can be a quadrangular prism. For example, the dimensions of the telescopic component 120 can be 2cm in length, 1.5cm in width, and 20cm in height. The maximum height of the telescopic component 120 and the base 110 after adjustment can be 40cm.

[0051] For example, in conjunction with reference Figure 1 and Figure 2 The support member 130 may include a support rod 1330, with a first mounting portion 1310 and a second mounting portion 1320 connected to the support rod 1330. Exemplarily, the support rod 1330 may include a support crossbar and a first and a second support vertical bar respectively connected to opposite ends of the support crossbar. The first mounting portion 1310 may be disposed on the first support vertical bar, the second mounting portion 1320 may be disposed on the second support vertical bar, and the rotating assembly 140 may be connected to the middle of the support crossbar. The overall structure of the testing device 10 can be simpler, resulting in lower production costs.

[0052] For example, the first mounting portion 1310 and / or the second mounting portion 1320 can be threaded or plugged into the support rod 1330. This simplifies the connection between the first mounting portion 1310 and / or the second mounting portion 1320 and the support rod 1330, making the installation process of the testing device 10 simple and efficient. Alternatively, the first mounting portion 1310 and / or the second mounting portion 1320 can be rotatably connected to the support rod 1330, for example, via a ball joint. This allows the first mounting portion 1310 and / or the second mounting portion 1320 to rotate relative to the support rod 1330 in any direction to accommodate different testing requirements.

[0053] For example, the support member 130 can also be threadedly connected to the telescopic member. The connection between the support member 130 and the telescopic member is simpler, and the installation process of the testing device 10 is simple and efficient. Alternatively, the support member 130 can also be plugged into the telescopic member 120. The connection is simpler, and the installation process of the testing device 10 is simple and efficient. Alternatively, the support member 130 and the telescopic member 120 can also be rotatably connected in other ways. For example, one end of the support member 130 and the telescopic member 120 can be provided with a spherical structure, and the other end can be provided with a limiting groove adapted to the spherical structure, with the spherical structure rotatably installed in the limiting groove. In this way, the support member 130 can rotate relative to the telescopic member 120 in any direction to obtain the position information of the test element in the corresponding direction.

[0054] For example, the first mounting part 1310 and the second mounting part 1320 can be located on the same horizontal plane. In this way, the distance information measured by the rangefinder can be directly converted into the position information of the test element in that direction, making the process of obtaining the position information of the test element more direct and simpler. The same horizontal plane here does not need to be absolutely horizontal; it is basically at the same height. The relative distance between the test element and other equipment (e.g., a HEPA filter) is required to be within a range (15cm to 30cm). Some errors in the position information of the test element measured by the rangefinder do not affect the results of the transfer window performance test.

[0055] In the description of this utility model, it should be understood that the directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0056] For ease of description, relative terms such as "above," "over," "on the upper surface of," and "above" are used here to describe the regional positional relationship of one or more components or features shown in the figures to other components or features. It should be understood that relative terms include not only the orientation of the component as depicted in the figure but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0057] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0058] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.
