This application provides a wearable device, a watchband mechanism, and a connecting component. The wearable device includes a watchband mechanism and a watch head mechanism. The watchband mechanism includes a watchband assembly and a connecting component connected to the watchband assembly. The connecting component is configured to be mounted on the watch head mechanism and detachably connected to it. The connecting component also has an air passage communicating with the watchband assembly. When the connecting component is mounted on the watchband assembly, the air passage is simultaneously connected to the watch head mechanism, and the watch head mechanism is configured to inflate and deflate the watchband assembly through the air passage. Through this configuration, the connecting component not only enables a detachable connection between the watchband assembly and the watch head mechanism but also secures the air passage to the watch head mechanism, eliminating the need for structures on the watch head mechanism required to secure the air passage. This increases the usable space of the watch head mechanism and reduces the limitations imposed on its design and layout due to space constraints.

This utility model relates to the field of cold storage technology and discloses a cold storage for categorized storage of meat products. The novel solution includes a cold storage unit with evenly spaced partitions inside. A storage frame is located at the top of each partition, and a water collection box is located at the bottom of the storage frame. A filter plate is located inside the storage frame. This utility model allows the filter plate to be moved upwards and removed from the storage frame using a pull rod. Pulling the handle forward moves the storage frame and water collection box forward, removing them from the cold storage unit. This ensures convenient use and cleaning of the device. Furthermore, by placing the pull rod within the clearance groove of the filter plate and the support column within the water collection box, the pull rod and water collection box avoid occupying storage space in the storage frame. By placing the water collection box and handle within the notches of the partitions, the water collection box and handle also avoid occupying space within the cold storage unit, thus increasing the usable space of the storage frame and the cold storage unit.

This utility model discloses a bottomless pet carrier, comprising: a top frame and a bottom frame, each with a U-shaped groove; side panels, installed at both ends within the U-shaped groove, with multiple side panels forming a through cavity open at both ends; a top plate, detachably mounted on the top frame, on which a cooling module is installed, one end of which penetrates the top plate and extends into the through cavity; a first water tray installed at the lower part of the top plate, with several air outlets on its edge; and a water pipe passing through the side panels and connected to the first water tray. A second water tray is installed on the side plate, one end of which is connected to the first water tray, and the other end to the water pipe. The bottomless design avoids the problem of difficult-to-clean bottom plates in traditional pet carriers, allowing users to directly rinse the inside of the carrier. The detachable top plate, combined with the first water tray, effectively expands the usable space inside the carrier, making it convenient for users to open the top plate for cleaning.

This invention belongs to the field of salt cavern gas storage engineering, specifically disclosing a method for brine treatment, gas storage, and cavity expansion in salt caverns. The method integrates brine absorption, gas storage, and expansion in two salt caverns, A and B. Through the formation of a hydraulic fracturing network and pressure drive by the brine, rapid in-situ absorption of large volumes of brine can be achieved on an engineering scale, significantly improving brine absorption efficiency. Furthermore, hydraulic fracturing modifies the cavity of salt cavern A, increasing the brine storage space in the reservoir, allowing for more efficient and larger-volume brine discharge from salt cavern B, expanding its usable space, and increasing the construction volume of salt cavern B as a compressed air storage facility. In addition, the method reduces or even eliminates the energy consumption and facility investment required for large-scale surface brine concentration and evaporation or long-distance transportation, significantly reducing processing costs.

The application provides a salt cave sediment breaking device and a brine discharging method suitable for multiple interlayers. The sediment breaking device comprises a production pipe, an intermediate pipe and a directional breaking device. The brine discharging method comprises the following steps: lowering the directional breaking device from the intermediate pipe into the salt cavity, starting from the sediment interface, breaking step by step in multiple directions from top to bottom, stopping breaking when the drill bit reaches the bottom of the salt cavity; taking out the directional breaking device from the intermediate pipe, lowering the intermediate pipe to the new sediment interface, discharging brine from the intermediate pipe through the gap as a gas injection channel, and injecting gas, at this time, the lower part of the salt cavity is dense sediment plus a small amount of brine, and the upper part is a gas storage clean space. The beneficial effects of the application are that the sediment is broken and stirred to reduce the sediment gap space as much as possible, so as to solve the problems of large sediment space proportion of the multiple interlayer salt cavity, difficult brine discharge and small available space of the salt cavity.

This utility model relates to the technical field of bacterial culture preparation devices, and in particular to a bacterial culture preparation device, comprising: a first filter having a first filter membrane, the first filter input end being connected to a first supply pump; a second filter having a second filter membrane, the second filter input end being connected to the first filter output end; and a third filter having a third filter membrane, the second filter input end being connected to the second filter output end; wherein the diameter of the pores on the first filter membrane is larger than the diameter of the pores on the second filter membrane, and the diameter of the pores on the second filter membrane is larger than the diameter of the pores on the third filter membrane. This utility model is beneficial for removing impurities from bacterial culture samples and enriching the bacterial culture.
