Description

Technical Field

[0001] This disclosure relates to the field of biochemical material storage and retrieval technology, and in particular to gate structure. Background Technology

[0002] Biological samples are a rapidly developing field in recent years, especially with the advancements in biopharmaceuticals and cell therapy, which have placed increasingly higher demands on their preservation. Hazardous chemicals may possess properties such as toxicity, corrosiveness, explosiveness, flammability, and oxidizing properties, including highly toxic chemicals and other chemicals that pose a threat to humans, facilities, and the environment. Therefore, hazardous chemicals also require adequate and reliable storage environments.

[0003] Existing biochemical items are stored or retrieved through windows. Most windows are constructed with latches, hinges, or linkages, which can easily obstruct or cause collisions when retrieving biochemical items, making storage and retrieval inconvenient. Furthermore, the large opening and closing motion of these windows can easily cause gas exchange between the inside and outside of the window, thus affecting the storage environment inside. Summary of the Invention

[0004] This disclosure provides a gate structure for separating a storage room from its exterior. The gate structure includes a protective cover, a fixing plate, and a baffle. The protective cover extends along a first direction and has a first end and a second end opposite to each other along the first direction. The protective cover has a cavity passing through the first end and the second end, with the first end communicating with the storage room. The fixing plate is fixed to the second end of the protective cover, perpendicular to the first direction, and covers a portion of the cavity. The baffle is located between the protective cover and the fixing plate, perpendicular to the first direction, and has a central axis extending along the first direction and a window passing through the baffle along the first direction. The baffle is rotatably connected to the second end about the central axis. The baffle has a first rotated position where the window is covered by the fixing plate and a second rotated position where the window is exposed to the fixing plate and communicating with the cavity.

[0005] The gate structure provided in this embodiment allows for the storage and retrieval of biochemical items when the baffle is rotated to a second rotation position where the window connects to the cavity. When the baffle is rotated to a first rotation position, it can again block the cavity, facilitating the retrieval of biochemical items. The rotation of the baffle minimizes the exchange of gases between the inside and outside of the window, reducing damage to the environment inside the cavity and storage room.

[0006] In some embodiments, the gate structure further includes a sealing assembly fixedly connected to the second end of the cover, the sealing assembly being located on the side of the baffle facing the cavity; when the baffle is in the first rotated position, the cavity is in a sealed state.

[0007] With this configuration, the sealing component can seal the cavity when the baffle is in the first rotation position, improving the sealing performance of the gate structure, reducing gas exchange between the cavity and the outside, and reducing damage to the environment inside the cavity and the storage room.

[0008] In some embodiments, the sealing assembly includes a sealing skeleton and a sealing element. The sealing skeleton is fixedly connected to the cover, and the sealing element is located between the sealing skeleton and the baffle. The sealing assembly has an opening that communicates with the cavity and is used to communicate with the window.

[0009] With this configuration, the sealing skeleton serves to support and mount the seals. When the baffle is in the second rotated position, it communicates with the cavity through the window and opening.

[0010] In some embodiments, the shield is cylindrical in shape, the projected profile of the baffle along the first direction is circular, the central axis of the shield coincides with the central axis of the baffle, and the projected profile of the seal along the first direction covers the projected profile of the opening along the first direction.

[0011] This design allows the circular baffle to rotate freely about its central axis perpendicular to the first direction. The projected profile of the seal along the first direction is larger than the opening, facilitating the access of biological materials when the baffle is in the second rotation position; and improving sealing performance when the baffle is in the first rotation position.

[0012] In some embodiments, the gate structure further includes a partition and a drive component. The partition is located within a cavity, which includes a conveying cavity and an equipment cavity separated by the partition. The conveying cavity is sealed and isolated from the equipment cavity. The drive component is located within the equipment cavity and includes a fixed end and a movable end. The fixed end is connected to a sealing element, and the movable end is drively connected to a baffle. The fixed end corresponds to the equipment cavity, and a window is provided to expose the conveying cavity.

[0013] This design seals and isolates the delivery chamber from the equipment chamber, preventing interference between the delivery of biochemical substances and the drive mechanism. It also prevents gas exchange between the delivery chamber and the equipment chamber. The drive mechanism facilitates the rotation of the baffle, thereby changing its position.

[0014] In some embodiments, the opening communicates with the equipment cavity, and the baffle, cover and partition in the first indexed position are sealed together by a sealing assembly to seal the conveying cavity.

[0015] This configuration ensures the sealing performance of the conveying chamber when the baffle is in the first indexed position.

[0016] In some embodiments, the gate structure further includes a transmission assembly, which includes a driving member and a driven member that are connected by transmission. The moving end is connected to the driving member, and the driven member is fixed to the side of the baffle facing the cavity.

[0017] With this configuration, the transmission components can easily drive the baffle to rotate, thereby allowing the baffle to switch between the first indexing position and the second indexing position.

[0018] In some embodiments, the driving element is an external gear, the driven element is an internal gear, and the driving element is a motor.

[0019] This configuration allows the motor to drive the baffle to rotate, thus changing its position. This makes both the opening speed and opening time of the gate adjustable and controllable. The internal and external gears work together to achieve high transmission precision, smooth transmission, no jamming, and low noise.

[0020] In some embodiments, the delivery chamber is filled with a cryogenic gas, reducing the temperature inside the chamber to below -20°C. Exemplarily, the delivery chamber is filled with an inert gas.

[0021] This configuration provides a sufficiently low-temperature environment for storing or retrieving biological samples. When the baffle is in its first rotated position, the fixed plate blocks the window and part of the cavity. The rotation of the baffle prevents gas exchange between the inside and outside of the window, thus minimizing temperature rise within the cavity and reducing the impact on the storage environment during biological sample storage and retrieval. The inert gas ensures the stability of the storage environment for hazardous chemicals.

[0022] In some embodiments, the projection profile of the window along the first direction is configured to be the same as the projection profile of the transported item along the first direction.

[0023] This design minimizes the window area when storing or retrieving biochemical items, thereby reducing heat exchange between the inside and outside of the cavity and minimizing damage to the environment inside the cavity and storage room. Attached Figure Description

[0031] To make the above-mentioned objects, features, and advantages of the embodiments of this disclosure more apparent and understandable, specific embodiments of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the embodiments of this disclosure. However, the embodiments of this disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the embodiments of this disclosure. Therefore, the embodiments of this disclosure are not limited to the specific embodiments disclosed below.

[0032] In the description of the embodiments of this disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing the embodiments of this disclosure and simplifying the description, 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, and therefore should not be construed as a limitation on the embodiments of this disclosure.

[0033] In this disclosure, unless otherwise explicitly stated and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Exemplarily, a first end may also be referred to as a second end, and a second end may also be referred to as a first end. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

The terms "installed," "set," and "fixed" can be broadly understood as "connected." Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0036] Existing biochemical items are stored or retrieved through windows. Most windows are constructed with latches, hinges, or linkages, which can easily obstruct or cause collisions when retrieving biochemical items, making storage and retrieval inconvenient. Furthermore, the large opening and closing motion of these windows can easily cause gas exchange between the inside and outside of the window, thus affecting the storage environment inside.

[0037] refer to Figure 1 , Figure 1 The overall structure of a gate structure 100 is shown. This disclosure relates to the field of biochemical material access technology.

[0038] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 This disclosure provides a gate structure 100. The gate structure 100 is used to separate a storage room (not shown) from the outside of the storage room. The gate structure 100 includes a protective cover 10, a fixing plate 50, and a baffle 20.

[0039] The shield 10 extends along a first direction. The shield 10 has a first end 11 and a second end 12 opposite to each other along the first direction. The shield 10 has a cavity 13. The cavity 13 extends through the first end 11 and the second end 12 along the first direction. The first end 11 is used to communicate with a storage chamber, that is, the cavity 13 is communicated with the storage chamber.

[0040] The fixing plate 50 is fixed to the second end 12 of the protective cover 10. The fixing plate 50 is perpendicular to the first direction. The fixing plate 50 covers a portion of the cavity 13. For example, the fixing plate 50 covers the lower half of the cavity 13.

[0041] A baffle 20 is located between the protective cover 10 and the fixing plate 50. The baffle 20 is connected to the second end 12. The baffle 20 is perpendicular to the first direction. The baffle 20 has a central axis. The central axis extends along the first direction. Exemplarily, along the first direction, the central axis may be located approximately at the centroid of the baffle 20, approximately at the center of its circumcircle, or at another predetermined position. Exemplarily, the baffle 20 can be counterweighted so that, without changing its design shape, the center of gravity of the baffle 20 is approximately located at the central axis.

[0042] The baffle 20 has a window 21. The window 21 passes through the baffle 20 along a first direction. The baffle 20 is rotatably connected to the second end 12 about a central axis. The baffle 20 has a first rotational position and a second rotational position. In the first rotational position, the window 21 of the baffle 20 is blocked by the fixing plate 50. In the second rotational position, the window 21 of the baffle 20 is not blocked by the fixing plate 50 and the window 21 communicates with the cavity 13.

[0043] The gate structure 100 provided in this embodiment comprises, in sequence along a first direction, a protective cover 10, a baffle 20, and a fixing plate 50. The fixing plate 50 fixes and blocks a portion of the cavity 13. When the baffle 20 is rotated to the first rotation position, the window 21 is blocked by the fixing plate 50, and the baffle 20 and the fixing plate 50 together block the cavity 13, preventing the retrieval of biological and chemical items. When the baffle 20 is rotated to the second rotation position, the window 21 is not blocked by the fixing plate 50 and the window 21 is connected to the cavity 13, facilitating the storage or retrieval of biological and chemical items by staff.

[0044] The gate structure 100 provided in this embodiment of the invention makes it difficult for the rotation of the baffle 20 to cause gas exchange between the inside and outside of the window 21, thereby reducing the damage to the environment inside the cavity 13 and the storage room.

[0045] For example, the projected profile of the baffle 20 along the first direction is the same as the projected profile of the shield 10 along the first direction. The projection of the fixing plate 50 along the first direction is greater than or equal to the projection of the window 21 along the first direction.

[0046] For example, the projection of the baffle 20 along the first direction is greater than the projection of the cavity 13 along the first direction. The fixing plate 50 is fixed to the lower half of the cover 10. The central axis of the baffle 20 is located below the central axis of the cavity 13. When the window 21 on the baffle 20 is rotated to below the central axis of the baffle 20, the baffle 20 is in a first rotated position, and the baffle 20 and the fixing plate 50 cover the cavity 13. When the window 21 on the baffle 20 is rotated to above the central axis of the baffle 20, the window 21 communicates with the cavity 13, and the baffle 20 is in a second rotated position. It can be understood that the central axis of the baffle 20 can also be located above the cavity 13.

[0047] For example, the projection of the fixing plate 50 along the first direction is semi-circular, and the fixing plate 50 is fixed to the lower half of the protective cover 10. In other embodiments, the fixing plate 50 may be fixed to the upper half, left half, or right half of the protective cover 10.

[0048] refer to Figure 3 and Figure 4 In some embodiments, the gate structure 100 further includes a sealing assembly 90. The sealing assembly 90 is fixedly connected to the second end 12 of the cover 10. The sealing assembly 90 is located on the side of the baffle 20 facing the cavity 13. When the baffle 20 is in the first rotated position, the cavity 13 is in a sealed state.

[0049] With this configuration, the sealing component 90 can seal the cavity 13 when the baffle 20 is in the first rotation position, thereby improving the sealing performance of the gate structure 100, reducing gas exchange between the cavity 13 and the outside, and reducing the damage to the environment inside the cavity 13 and the storage room.

[0050] refer to Figure 3 and Figure 4 In some embodiments, the sealing assembly 90 includes a sealing skeleton 92 and a sealing element 91. The sealing skeleton 92 is fixedly connected to the cover 10, and the sealing element 91 is located between the sealing skeleton 92 and the baffle 20. The sealing assembly 90 has an opening 93, which communicates with the cavity 13 and is used to communicate with the window 21.

[0051] With this configuration, the sealing frame 92 is used to support and mount the seal 91. When the baffle 20 is in the second rotated position, it communicates with the cavity 13 through the window 21 and the opening 93.

[0052] For example, the projected profile of the sealing frame 92 along the first direction is the same as the projected profile of the shield 10 along the first direction. The sealing frame 92 is fixedly connected to the inner wall of the shield 10.

[0053] For example, the projected profile of the seal 91 along the first direction is semi-circular. The projected profile of the opening 93 along the first direction is also semi-circular.

[0054] For example, the sealing skeleton 92 is in close contact with the side of the baffle 20 facing the cavity 13.

[0055] For example, the projection profile of the opening 93 along the first direction is the same as the projection profile of the window 21 along the first direction.

[0056] refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the shield 10 is cylindrical in shape. The projected profile of the baffle 20 along the first direction is circular. The central axis of the shield 10 coincides with the central axis of the baffle 20. The projected profile of the seal 91 along the first direction covers the projected profile of the opening 93 along the first direction.

[0057] With this configuration, the circular baffle 20 can be easily rotated about its central axis perpendicular to the first direction. The projected profile of the seal 91 along the first direction is larger than that of the opening 93, which facilitates the access of biological and chemical items when the baffle 20 is in the second rotation position and improves the sealing performance when the baffle 20 is in the first rotation position.

[0058] For example, the projected profile of the baffle 20 along the first direction is the same as the projected profile of the shield 10 along the first direction.

[0059] In other embodiments, the baffle 20 may be square or rectangular, the central axis of the shield 10 coincides with the central axis of the baffle 20, and the projected profile of the baffle 20 along the first direction can cover the projected profile of the shield 10 along the first direction.

[0060] It is understood that the shield 10 can also be a cuboid, or the projection shape of the shield 10 along the first direction can be a square, rectangle, polygon, etc. The central axis of the shield 10 coincides with the central axis of the baffle 20, and the projection outline of the baffle 20 along the first direction can cover the projection outline of the shield 10 along the first direction.

[0061] For example, the projected outline of the opening 93 along the first direction can be a polygon, a square, a rectangle, or any irregular shape. The projected outline of the seal 91 along the first direction can be a polygon, a square, or a rectangle, and the projected outline of the seal 91 along the first direction covers the projected outline of the opening 93 along the first direction.

[0062] refer to Figure 3In some embodiments, the gate structure 100 further includes a partition 60 and a drive member 30. The partition 60 is located within a cavity 13, which includes a conveying cavity 131 and an equipment cavity 132 separated by the partition 60. The conveying cavity 131 is sealed and isolated from the equipment cavity 132. The drive member 30 is located in the equipment cavity 132 and includes a fixed end 31 and a movable end 32. The fixed end 31 is connected to a seal 91, and the movable end 32 is drively connected to a baffle 20. The fixed plate 50 corresponds to the equipment cavity 132, and the window 21 is used to expose the conveying cavity 131.

[0063] This configuration seals and isolates the conveying chamber 131 from the equipment chamber 132, preventing interference between the conveying of biochemical substances and the drive unit 30. It also prevents gas exchange between the conveying chamber 131 and the equipment chamber 132. The drive unit 30 facilitates the rotation of the baffle 20, thereby changing its position.

[0064] For example, the partition 60 divides the cavity 13 into two equal parts, with the upper part of the cavity 13 being a conveying cavity 131 and the lower part being a device cavity 132. The fixing plate 50 is disposed corresponding to the device cavity 132 along a first direction. In other embodiments, the upper part of the cavity 13 is the device cavity 132 and the lower part is the conveying cavity 131.

[0065] For example, the projection of the delivery cavity 131 along the first direction is smaller than the projection of the device cavity 132 along the first direction.

[0066] In other embodiments, the device cavity 132 does not need to be sealed.

[0067] refer to Figure 2 In some embodiments, the opening 93 communicates with the device cavity 132, and the baffle 20, the cover 10 and the partition 60 in the first rotation position are sealed together by the sealing assembly 90 to seal the conveying cavity 131.

[0068] This configuration ensures the sealing performance of the conveying cavity 131 when the baffle 20 is in the first indexed position.

[0069] refer to Figure 3 and Figure 4 In some embodiments, the gate structure 100 further includes a transmission assembly 70. The transmission assembly 70 includes a driving member 71 and a driven member 72 that are connected in a transmission manner. The movable end 32 is connected to the driving member 71, and the driven member 72 is fixed to the side of the baffle 20 facing the cavity 13.

[0070] With this configuration, the transmission assembly 70 can easily drive the baffle 20 to rotate, thereby allowing the baffle 20 to switch between the first indexing position and the second indexing position.

[0071] For example, the drive member 30 is connected to the transmission member through the sealing frame 92, and the transmission member is located between the sealing frame 92 and the baffle 20.

[0072] refer to Figure 4 In some embodiments, the driving member 71 is an external gear, the driven member 72 is an internal gear, and the driving member 30 is a motor.

[0073] With this configuration, the motor drives the baffle 20 to rotate, thereby changing its position, making the opening speed and opening time of the gate structure 100 adjustable and controllable. The internal and external gears have high transmission precision, smooth transmission, no jamming, and low noise.

[0074] For example, the fixed end 31 of the motor is fixed to the cover 10, and the movable end 32 of the motor is connected to the external gear. The motor drives the external gear to rotate around the central axis in a direction perpendicular to the first direction. The external gear meshes with the internal gear and thus drives the internal gear to rotate. Since the internal gear is fixedly connected to the baffle 20, the baffle 20 is driven to rotate by the internal gear.

[0075] In some embodiments, the delivery chamber 131 is filled with cryogenic gas, so that the temperature inside the device chamber 132 is below -20°C.

[0076] This configuration provides a sufficiently low-temperature environment for storing or retrieving biological samples. When the baffle 20 is in the first rotated position, the fixed plate 50 blocks the window 21 and part of the cavity 13. After the baffle 20 rotates, it is difficult for gas to exchange between the inside and outside of the window 21, and the temperature inside the cavity 13 is not easily raised, reducing the impact on the storage environment when storing or retrieving biological samples. The low-temperature environment effectively stops the function of the biological sample and allows the biological sample to maintain its activity for a long time.

[0077] In some embodiments, the delivery chamber 131 is filled with an inert gas. The inert gas ensures the stability of the storage environment for hazardous chemicals. The inert gas is chemically very inert and can be used as a protective gas for storing hazardous chemicals. Exemplarily, the delivery chamber 131 is filled with a cryogenic inert gas.

[0078] refer to Figure 1 and Figure 5 In some embodiments, the projection profile of window 21 along the first direction is configured to be the same as the projection profile of the transported item along the first direction.

[0079] This design minimizes the area of ​​window 21 when storing or retrieving biochemical items, thereby reducing heat exchange inside and outside the cavity 13 and minimizing damage to the environment inside the cavity 13 and the storage room.

[0080] In other embodiments, the projected outline of window 21 along the first direction can also be a semicircle, an irregular shape, etc. The projected outline of fixing plate 50 along the first direction can be the same as or different from the projected outline of window 21 along the first direction, as long as the projected outline of fixing plate 50 along the first direction can cover the projected outline of window 21 along the first direction.

[0081] In other embodiments, the projected profile of window 21 along the first direction is different from the projected profile of the transported item along the first direction.

[0082] refer to Figure 1 and Figure 2 In some embodiments, the gate structure 100 further includes an identification device 40 located on the side of the baffle 20 facing away from the cavity 13. The identification device 40 is communicatively connected to the drive member 30. The identification device 40 is used to identify the user.

[0083] This setup allows for timely user identification through pre-entry of information, granting access to the device upon confirmation. After identifying the user, the identification device 40 transmits a signal to the drive unit 30, thereby controlling the position of the baffle 20. This helps prevent unauthorized personnel from accessing biochemical materials, reducing errors and confusion.

[0084] For example, the identification device 40 can be a face recognition or fingerprint recognition device.

[0085] refer to Figure 1 In some embodiments, the gate structure 100 also includes a sensing device 80. The sensing device 80 is located on the side of the partition 60 facing the conveying cavity 131. The sensing device 80 is relatively close to the second end 12.

[0086] With this setup, the sensor 80 can scan the information of the transported biochemical items, making the storage and retrieval of biochemical items fully controllable.

[0087] In other embodiments, the sensing device 80 may also be installed on the inner wall of the cover 10, the sensing device 80 is located in the conveying cavity 131, and the sensing device 80 faces the partition 60.

[0088] For example, the sensing device 80 is a radio frequency identification (RFID). When the biochemical item is transported into the radio frequency range in the conveying cavity 131, the QR code on the biochemical item is sensed, so that the sensing device 80 can obtain the detailed information of the biochemical item and transmit it to the item management department.

[0089] For example, the sensing device 80 is an optocoupler. When the biochemical item is transported in the conveying chamber 131 to the location of the optocoupler, a coupling signal is generated, so that the sensing device 80 can obtain detailed information about the biochemical item and transmit it to the item management department.

[0090] For example, the sample retrieval process is as follows: When storing biochemical items, the baffle 20 is in the first rotation position, the window 21 is blocked by the fixing plate 50, and the conveying cavity 131 is sealed by the sealing assembly 90. When biochemical items need to be retrieved, the staff comes to the identification device 40 for identification. After identification, the driving component 30 can be operated to drive the transmission assembly 70 to rotate, thereby rotating the baffle 20, so that the window 21 rotates out from behind the fixing plate 50 until the window 21 is fully connected to the conveying cavity 131, at which point the baffle 20 is in the second rotation position. Biochemical items are stored and retrieved through the window 21 via the conveying cavity 131. During the storage and retrieval process, the information of the biochemical items is recorded by the sensing device 80. After storage and retrieval are completed, the driving component 30 drives the baffle 20 back to the first rotation position.

[0091] The technical features of the above-disclosed embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] In the embodiments disclosed above, unless otherwise explicitly specified and limited, the execution order of each step is not restricted. For example, they can be executed in parallel or sequentially in different orders. The sub-steps of each step can also be executed alternately. Various forms of processes described above can be used, and steps can be reordered, added, or deleted, as long as the desired result of the technical solution provided by the embodiments of this disclosure can be achieved, and no limitations are imposed herein.

[0093] The embodiments disclosed above merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
