Description

Technical Field

[0001] This utility model belongs to the technical field of chemical combination cabinets, and more specifically, it relates to a chemical combination cabinet with zoned fire extinguishing function. Background Technology

[0002] Laboratories and chemical plants often use chemical combination cabinets to store and organize chemical reagents to reduce safety hazards during storage and use.

[0003] For example, existing application number CN202323014791.7 discloses an intelligent monitoring chemical combination cabinet, which relates to the technical field of chemical combination cabinets. The cabinet includes a laboratory cabinet composed of multiple combination cabinets. One end of each combination cabinet has a limiting structure, which includes a disc and a fixing block. One end of the fixing block has a storage slot, and one end of the disc has a fixing rod fixedly installed. A rotating plate is rotatably installed on the outer wall of the fixing rod, and a blocking plate is fixedly installed on one end of the rotating plate. This utility model combines several sets of combination cabinets to form the required laboratory cabinet, effectively solving the problems of small or large laboratory spaces, as well as the issues of many types and small quantities of medicines. Furthermore, the combined laboratory cabinet can be used and managed by multiple people, and different specifications and sizes of dedicated storage laboratory cabinets can be freely combined according to site requirements, improving the practicality of the combination cabinet.

[0004] Based on the above, in the actual application of chemical combination cabinets, the cabinet depth is usually designed to be deep in order to increase storage capacity, and chemical reagents are usually densely arranged in order to save cabinet space. In the process of storing and retrieving chemical reagents inside the cabinet, the staff needs to reach their arms into the cabinet. Since the staff's shoulders and elbows are restricted by the edge of the cabinet, the range of hand movement is reduced, making it difficult to accurately control the grasping action. It is very easy for the staff to touch the surrounding reagents due to slight hand shaking, causing the reagents to be spilled and broken. After the chemical reagents are spilled and broken, they will not only easily cause environmental pollution, increase the maintenance cost and safety management difficulty of the laboratory, but also bring safety risks to the personal safety of the staff and the surrounding environment. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a chemical combination cabinet with zoned fire suppression function. This addresses the issue that in practical applications of chemical combination cabinets, the cabinet depth is typically designed to be deep to increase storage capacity, and chemical reagents are usually densely packed to save space. During the retrieval of chemical reagents inside the cabinet, staff need to extend their arms deep into the cabinet. Because the staff's shoulders and elbows are restricted by the cabinet edges, their hand range of motion is reduced, making it difficult to accurately control the grasping action. Slight hand movements can easily cause spillage and damage to surrounding reagents. Spillage and damage not only easily pollute the environment and increase laboratory maintenance costs and safety management difficulties, but also pose safety risks to staff and the surrounding environment.

[0006] The purpose and effectiveness of this utility model's chemical combination cabinet with zoned fire suppression function are achieved through the following specific technical means: A chemical combination cabinet with zoned fire suppression function includes a supporting cabinet body, cabinet doors, flame-retardant positioning plates, a storage and retrieval auxiliary mechanism, and a positioning auxiliary mechanism. A longitudinal flame-retardant plate is fixedly connected to the inner side of the supporting cabinet body. Multiple cabinet doors are evenly arranged and hinged to the outer side of the front end face of the supporting cabinet body. Multiple flame-retardant positioning plates are arranged vertically and fixedly connected to the left and right sides of the inner end of the supporting cabinet body. A load-bearing support plate is rotatably connected to the top end face of each flame-retardant positioning plate via a connecting shaft. The storage and retrieval auxiliary mechanism is located between the connecting shaft and the flame-retardant positioning plates. Multiple receiving slots are arranged circumferentially on the inner side of the load-bearing support plate. The positioning auxiliary mechanism is located inside the receiving slots. The positioning auxiliary mechanism includes multiple clamping auxiliary frames, which are circumferentially arranged and elastically positioned inside the receiving slots. The clamping auxiliary frames have an arc-shaped plate structure.

[0007] Furthermore, an anti-overflow bracket is fixedly connected to the outer side of the top end face of the flame-retardant positioning plate; a guide groove is opened at the outer end of the anti-overflow bracket; and a sealing plug is inserted into the inner side of the guide groove.

[0008] Furthermore, the access assistance mechanism includes: a transmission auxiliary shaft, a drive worm wheel, and a drive worm. The transmission auxiliary shaft is vertically rotatably disposed at the outer end of the connecting support shaft; the drive worm wheel is coaxially and fixedly connected to the outer side of the lower end of the connecting support shaft; the drive worm is coaxially and fixedly connected to the inner end face of the transmission auxiliary shaft, and the drive worm and the drive worm wheel mesh with each other.

[0009] Furthermore, the access assistance mechanism also includes a transmission bevel gear and a drive bevel gear. The transmission bevel gear is coaxially and fixedly connected to the outer end face of the transmission auxiliary shaft. The drive bevel gear is vertically rotatably disposed outside the transmission bevel gear and is rotatably connected to the flame-retardant positioning plate via an operating shaft. The drive bevel gear and the transmission bevel gear mesh with each other, and the number of teeth of the drive bevel gear is greater than the number of teeth of the transmission bevel gear.

[0010] Furthermore, the clamping auxiliary frame and the receiving groove are elastically connected by an elastic extrusion member; an auxiliary inclined plate is fixedly connected to the outer side of the top end face of the clamping auxiliary frame; the auxiliary inclined plate is an arc-shaped inclined plate structure.

[0011] Furthermore, a limiting guide is fixedly connected to the bottom end face of the clamping auxiliary frame; the limiting guide is a convex frame structure; a limiting guide groove is opened on the inner side of the bearing support plate at the position aligned with the limiting guide; the limiting guide and the limiting guide groove on the same side are slidably arranged.

[0012] Compared with the prior art, the present invention has the following beneficial effects: When using this invention, staff do not need to extend their arms deep into the cabinet. They can transfer the reagents from the inside to the front of the cabinet by rotating the device. This greatly reduces the restriction on the movement of the shoulders and elbows, significantly improving the accuracy of the grasping action. It also reduces the risk of spillage and damage caused by the hand shaking and touching the surrounding reagents, ensuring the personal safety of the operators and reducing the potential safety hazards caused by reagent leakage. In use, this utility model adopts a combination design of arc-shaped clamping auxiliary frame and elastic squeezing component in the positioning auxiliary mechanism to enhance reagent stability and reduce accidental tipping. At the same time, the arc-shaped inclined structure of the auxiliary inclined plate reduces the insertion resistance during storage and enhances the guiding and limiting effect on the bottle. In use, the longitudinal flame-retardant plate and flame-retardant positioning plate divide the cabinet into multiple independent storage units, each equipped with an independent cabinet door, to achieve physical isolation of different types of chemical reagents, preventing cross-contamination and reaction risks. The interlocking structure of the sealing flame-retardant strip and the sealing guide groove forms multiple flame-retardant sealing defenses when the cabinet door is closed, which not only prevents the cross-area diffusion of volatile gases, but also creates conditions for zoned fire extinguishing. When a fire occurs in a certain unit, the corresponding cabinet door can be closed individually to achieve local suffocation fire extinguishing, preventing the fire from spreading to the entire cabinet.
