Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder storage, in particular to a gas cylinder safety cabinet. Background Art

[0002] Most gas cylinders contain flammable or toxic gases. Since the gas in the cylinders is under high pressure, many issues need to be paid attention to when placing the cylinders. Nowadays, many application fields use cylinder cabinets to place cylinders. The cylinder cabinets can protect the cylinders from fires outside the cabinets and protect surrounding objects from internal fires.

[0003] For example, a gas cylinder cabinet (Announcement No.: CN209677842U) includes a cabinet body, a cabinet door, and a fixing device arranged in the cabinet body for fixing the gas cylinder, and the cabinet body and the cabinet door are connected by a hinge; the fixing device includes a limit plate and a buckle part for buckling the limit plate to the inner wall of the cabinet body, and the inner wall of the cabinet body is provided with a buckle groove for buckling the buckle part; the limit plate is provided with an arc-shaped groove for the gas supply bottle to be inserted and fixed, and locking rings are provided on both sides of the arc-shaped groove; the top of the cabinet body is provided with an exhaust port, and the top of the cabinet body is provided with an exhaust fan for discharging the gas inside the cabinet body out of the cabinet body at the exhaust port. The utility model has two groups of buckle grooves with different distances from the bottom of the cabinet body on the inner wall of the cabinet body along the height direction of the cabinet body. When installing the limit plate, the limit plate can be installed on the buckle groove of the corresponding height according to the height of the gas cylinder, which is convenient for fixing gas cylinders of different heights, fixing the gas cylinders more firmly, and improving the safety factor.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, the gas cylinder is fixed by the arc-shaped groove on the limit plate in cooperation with the locking ring and the gas cylinder fixing belt. When the gas cylinder fixing belt cooperates with the locking ring to fix the gas cylinder, a gap is easily left between the gas cylinder fixing belt and the gas cylinder. When the cabinet is collided or moved, the gas cylinder may still shake, and when the gas cylinder fixing belt is fixed with the locking ring, there may be a risk of loose fixation. Therefore, we need to propose a gas cylinder safety cabinet. Utility Model Content

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] A gas cylinder safety cabinet comprises a cabinet body 1, one side of the cabinet body 1 is symmetrically hinged with two sets of cabinet doors 2, and the inner wall of the cabinet body 1 is provided with a clamping mechanism 3 for clamping and fixing the gas cylinder;

[0028] The clamping mechanism 3 includes a fixing plate 31, which is fixedly mounted on the side walls of the cabinet 1. A double-axis motor 32 is fixedly mounted on one side of the fixing plate 31. One end of the two output shafts of the double-axis motor 32 is fixedly connected with a double-axis threaded rod 33. The opposite ends of the two groups of double-axis threaded rods 33 are rotatably connected to the inner walls of the cabinet 1 on both sides. The outer walls of both ends of the double-axis threaded rods 33 are threadedly connected with sliding plates 34. The opposite sides of one end of the two groups of sliding plates 34 are fixedly connected with arc-shaped clamping plates 35 used in conjunction with them. Four groups of arc-shaped clamping plates 35 form a fixed structure for clamping and fixing two groups of gas cylinders.

[0029] An exhaust box 4 is fixedly installed on the top of the cabinet 1, and a gas concentration sensor 6 for monitoring whether the gas cylinder is leaking is fixedly installed on the bottom of the exhaust box 4. An exhaust component for exhausting and filtering the gas inside the cabinet 1 is arranged inside the exhaust box 4.

[0030] The exhaust assembly includes a mounting frame 9, which is fixedly embedded in the bottom of the exhaust box 4. Two sets of exhaust fans 10 are fixedly installed inside the mounting frame 9 through brackets to facilitate the exhaust fans 10 to start, extract the internal gas of the cabinet 1 and transport it to the exhaust box 4.

[0031] The top of the exhaust box 4 is symmetrically provided with two groups of stepped grooves 11 connected to the inside of the exhaust box 4. The inside of the two groups of stepped grooves 11 can be detachably installed with activated carbon filters 12, so that the gas can be filtered by the two groups of activated carbon filters 12 installed by plugging.

[0032] The two groups of activated carbon filters 12 are respectively located on both sides of the installation frame 9 , and the side walls of the exhaust box 4 on the opposite side of the two groups of activated carbon filters 12 are provided with air outlet mesh holes 13 to facilitate the discharge of filtered gas from the air outlet mesh holes 13 .

[0033] The fixed plate 31 is located on one side of the two groups of bidirectional threaded rods 33 and is provided with an avoidance groove 37 for avoiding the sliding plate 34. The outer wall of the sliding plate 34 is slidably connected to the inner wall of the avoidance groove 37, so that the two groups of sliding plates 34 threadedly connected on the corresponding bidirectional threaded rods 33 can be guided and avoided through the avoidance groove 37.

[0034] Two groups of limit slide grooves 5 are provided on the inner wall of one side of the cabinet body 1, and two groups of limit sliders 36 are slidably connected inside the two groups of limit slide grooves 5.

[0037] Working principle: When the utility model is used, the dual-axis motor 32 in the clamping mechanism 3 drives the two sets of bidirectional threaded rods 33 to rotate, so that the sliding plates 34 threadedly connected on the outer walls of the two sets of bidirectional threaded rods 33 move, and the limiting slide groove 5 cooperates with the limiting slider 36 to limit the sliding plate 34 when it moves, so that the relatively arranged arc-shaped clamping plates 35 move relatively, and the gas cylinders are clamped and fixed. Two sets of gas cylinders can be clamped and fixed at the same time, which can prevent the cabinet from being hit or the gas cylinders from shaking when moving to a certain extent, and improve the stability of the gas cylinder fixation;

[0038] Through the cooperation of the gas concentration sensor 6 and the control panel 7, when gas leakage occurs in the gas cylinder, the signal can be effectively transmitted to the control panel 7, and then the exhaust fan 10 in the exhaust assembly is controlled by the control panel 7 to start, and the gas inside the cabinet 1 is extracted and transported to the exhaust box 4. The gas is filtered by two groups of activated carbon filters 12 inserted in the exhaust box 4, and the filtered gas is discharged through the air outlet holes 13 on both sides of the exhaust box 4, which can effectively prevent the gas from affecting the surrounding environment. At the same time, the control panel 7 controls the buzzer 8 to alarm, thereby increasing the safety of the device.
