Description

Technical Field

[0001] This utility model belongs to the field of fruit tree pollination technology, specifically relating to an ultra-low temperature storage device for active pollen used in fruit tree pollination. Background Technology

[0002] The core objective of ultra-low temperature storage of fruit tree pollen is to maximally inhibit the physiological and biochemical activities of pollen at extremely low temperatures (usually -196℃ to -80℃), causing it to enter a "dormant" state, thereby maintaining its germination rate and pollination ability for a long period (years or even decades). Ultra-low temperature storage of pollen generally adopts liquid nitrogen immersion storage. Existing pollen storage tanks are generally designed with an integral top, which requires opening the entire tank opening during pollen storage and retrieval. This leads to continuous evaporation of liquid nitrogen and rapid loss of cold energy, requiring frequent replenishment of liquid nitrogen, which increases the operation and maintenance costs of the storage equipment. Therefore, an ultra-low temperature storage device for active pollen for fruit tree pollination is proposed. Utility Model Content

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Example 1

[0033] Reference Figures 1-3 This is the first embodiment of the present invention, which provides an ultra-low temperature storage device for active pollen used in fruit tree pollination, including a low temperature tank mechanism 100 and a storage mechanism 200.

[0034] Specifically, the cryogenic tank mechanism 100 includes a tank body 101 with a Dewar tank structure, and the outer wall of the tank body 101 is provided with a liquid nitrogen replenishment pipe 102 for replenishing liquid nitrogen and a pressure relief valve 103 from top to bottom.

[0035] The storage mechanism 200 includes a storage cylinder 201. The bottom of the storage cylinder 201 has a communication port 202 that communicates with the tank body 101. The storage cylinder 201 is equipped with a placement component 204. The placement component 204 includes a storage and retrieval cylinder 204a installed inside the storage cylinder 201. The storage and retrieval cylinder 204a is arranged in a horizontal array with multiple mesh horizontal plates 204b for placing pollen samples. Liquid nitrogen inside the tank body 101 can enter the storage cylinder 201 through the communication port 202 for use. At the same time, the mesh horizontal plates 204b can also facilitate the diffusion of liquid nitrogen to various parts inside the storage and retrieval cylinder 204a.

[0036] Preferably, multiple storage cylinders 201 are arranged in a circular array about the tank 101. The arrangement of multiple storage cylinders 201 divides the equipment into several independent storage units, so that when taking or taking samples from a single storage cylinder 201, it is not necessary to open the entire tank 101, but only the corresponding storage cylinder 201 needs to be opened, which greatly reduces the loss of cold energy.

[0037] In use, the user simply pulls out the corresponding storage cylinder 204a, stores or retrieves the sample, and then puts it back in. The array of multiple storage cylinders 201 reduces the contact between liquid nitrogen and the outside environment during sample retrieval and placement, thereby preventing the loss of cold energy and reducing the consumption of liquid nitrogen.

[0038] Example 2

[0039] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a storage mechanism 200.

[0040] Specifically, the storage mechanism 200 also includes a connecting member 203 installed at the bottom of the inner wall of the storage cylinder 201 for controlling the opening and closing of the connecting port 202, and a control member 205 installed around the placement member 204 and connected to the top of the tank body 101.

[0041] Furthermore, the connecting member 203 includes a rotating ring 203a rotatably disposed within the storage cylinder 201. Two drive grooves 203b are symmetrically formed at the center of the bottom surface of the rotating ring 203a. A drive head 203c is movably embedded inside each of the two drive grooves 203b. A sealing plate 203d is provided on the outer side of each of the two drive heads 203c. At the same time, a locking ridge 203f is fixed on the outer periphery of the surface of the rotating ring 203a. A positioning groove 203e for guiding the sealing plate 203d is symmetrically formed at the bottom of the inner wall of the storage cylinder 201. The two ends of the drive head 203c are located in the drive groove 203b and the positioning groove 203e, respectively.

[0042] The placement component 204 also includes a locking groove 204c formed on the inner wall of the storage cylinder 204a, a lifting groove 204d formed on the outer wall of the storage cylinder 204a, and a taking groove 204e.

[0043] The locking ridge 203f and the locking groove 204c are designed to fit together, so that when the storage cylinder 204a rotates, the rotating ring 203a can be driven to rotate synchronously through the cooperation of the two.

[0044] Preferably, the drive groove 203b is arc-shaped, and the two ends of the drive head 203c are located in the drive groove 203b and the positioning groove 203e respectively. When the storage cylinder 204a rotates counterclockwise, the two closing plates 203d can move inward towards each other under the combined action of the drive groove 203b and the positioning groove 203e on the drive head 203c, thus closing the communication port 202 and further reducing the loss of cold energy during the retrieval of the storage cylinder 204a.

[0045] The control component 205 includes a control seat 205a rotatably disposed on the top of the tank body 101, and a control head 205b is fixed on the inner wall of the control seat 205a.

[0046] Furthermore, the control head 205b is in sliding engagement with the lifting groove 204d and the extraction groove 204e. The lifting groove 204d is spirally inclined downwards in a counterclockwise direction. Therefore, if the storage cylinder 204a is to be extracted by the control seat 205a, the control seat 205a needs to rotate counterclockwise. At this time, the rotation direction of the control seat 205a is consistent with the rotation direction of the rotating ring 203a to close the connecting port 202. Thus, when the control seat 205a rotates counterclockwise and pushes out the storage cylinder 204a through the engagement of the lifting groove 204d and the control head 205b, the storage cylinder 204a is not restricted by rotation at this time, and thus, the extraction is achieved by the control head 205b. The transmission between the control head 205b and the locking ridge 203f drives the rotating ring 203a to rotate synchronously, causing the two closing plates 203d to contact and close the connecting port 202. Subsequently, the rotating ring 203a is difficult to rotate further, and the rotation of the storage cylinder 204a can be restricted by the locking ridge 203f. At this time, as the control base 205a rotates further, the control head 205b can push the storage cylinder 204a up for the user to pick up and use. The extraction slot 204e is vertically set. After the storage cylinder 204a is raised by the lifting slot 204d, the vertical extraction slot 204e can ensure that the storage cylinder 204a can be pulled out smoothly.

[0047] When in use, when the user needs to retrieve or place a sample, first rotate the control seat 205a counterclockwise. Under the power transmission of the storage cylinder 204a, the rotating ring 203a rotates to close the connecting port 202 with the help of the sealing plate 203d to prevent the continuous loss of cold energy during storage and retrieval. After the connecting port 202 is closed, continue to rotate the control seat 205a. At this time, the storage cylinder 204a can be raised with the cooperation of the control head 205b and the lifting groove 204d. Then, the user can use tools such as grippers or manually pull out the storage cylinder 204a for storage and retrieval.

[0048] In summary, by setting up the connecting component 203, the connecting port 202 can be temporarily closed during the pollen sample retrieval process to avoid continuous evaporation of liquid nitrogen and reduce cold loss. This eliminates the need for frequent replenishment of liquid nitrogen, reducing the operation and maintenance costs of the storage equipment. At the same time, with the cooperation of the control component 205 and the placement component 204, it is convenient to take out the storage tube 204a, making it easy for users to pick up and put in samples. Furthermore, by combining the rotation and lifting of the placement component 204 by the control component 205 with the rotation and closing of the connecting component 203, the two are linked together to achieve automatic closing and opening of the connecting port 202 when the storage tube 204a is taken out and put back, making the use of the equipment more convenient.
