DETAILED DESCRIPTION

[0033] The utility model will be further described below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 3 As shown, the cooling device for a gas cylinder of the utility model comprises: a cooling box 1, wherein the cooling box 1 contains a coolant; a gas cylinder tray 3, wherein the gas cylinder tray 3 is arranged in the cooling box 1 and is used to place the gas cylinder; a telescopic mechanism, wherein the telescopic mechanism is arranged on the top of the cooling box 1, wherein the telescopic end of the telescopic mechanism is connected to the gas cylinder tray 3, and the telescopic mechanism can drive the gas cylinder tray 3 to rise and fall in the vertical direction.

[0035] Specifically, the cooling device drives the gas cylinder tray 3 to rise and fall in the vertical direction through the telescopic mechanism, and the gas cylinder placed on the gas cylinder tray 3 can be placed in the coolant for cooling, and it is convenient to take and put the gas cylinder. In this way, the gas cylinder is cooled by heat transfer through the coolant, which replaces natural cooling and can shorten the cooling time and improve efficiency, so as to ensure that the air respirator can be used normally.

[0036] Furthermore, the cooling box 1 may be a rectangular parallelepiped structure with an opening facing upward, and the coolant may be cooling water.

[0037] In an example, Figure 1 and Figure 2 As shown, the telescopic mechanism includes: a limit plate 11, which is arranged at the box opening on the top of the cooling box 1; a mounting stand 14, which is arranged on the limit plate 11; an electric telescopic rod 2, the fixed end of the electric telescopic rod 2 is fixedly connected to the mounting stand 14, and the telescopic end of the electric telescopic rod 2 passes through the limit plate 11 and is fixedly connected to the gas cylinder tray 3.

[0038] Specifically, the limit plate 11 is fixedly mounted across the top of two opposite walls of the cooling box 1, and the limit plate 11 is correspondingly arranged above the gas cylinder support plate. The limit plate 11 is used to fix the mounting stand 14 and can limit the rising height of the gas cylinder tray 3. The mounting stand 14 is a door-type frame structure, which is mounted across the middle of the limit plate 11. The fixed end of the electric telescopic rod 2 is fixed to the top frame of the mounting stand 14, and its telescopic end passes through the limit plate 11 and is fixedly connected to the gas cylinder tray 3, so that the electric telescopic rod 2 can drive the gas cylinder tray 3 to rise and fall in the vertical direction when it is electrically extended.

[0039] In an example, Figures 1 to 3 As shown, the limiting plate 11 is provided with a plurality of limiting through holes 12 , and the gas cylinder tray 3 is provided with a plurality of placement grooves 31 , and the limiting through holes 12 correspond to the placement grooves 31 one by one.

[0040] Furthermore, the limiting plate 11 and the gas cylinder tray 3 are both rectangular structures, and the limiting through holes 12 and the placement grooves 31 are generally evenly distributed with 1 to 3 in the width direction and 2 to 6 in the length direction. When the gas cylinder is placed, the bottle body passes through the limiting through hole 12 for limiting, and the bottom of the bottle is placed in the placement groove 31 for positioning, which can better limit the position of the gas cylinder and ensure that the gas cylinder can be raised and lowered with the gas cylinder tray 3, so that the gas cylinder can be taken in and placed in the cooling box 1.

[0041] In an example, Figure 1 and Figure 4 As shown, a sponge wiping sleeve 4 in a circular ring structure is inserted into the limiting through hole 12, and the sponge wiping sleeve 4 is used to wipe the coolant on the gas cylinder.

[0042] In an example, Figure 2 and Figure 4 As shown, a circular ring positioning block 41 is disposed on the outer side of the sponge wiping sleeve 4 , a positioning inner cavity 13 is formed on the hole wall of the limiting through hole 12 , and the circular ring positioning block 41 is inserted into the positioning inner cavity 13 .

[0043] In an example, Figure 3 As shown, a through leakage hole 32 is provided at the bottom of the placement groove 31. The leakage hole 32 can be set to be multiple and evenly distributed at the bottom of the placement groove 31.

[0044] In an example, Figure 1 and Figure 2 As shown, the mounting bracket 14 spans the middle of the limiting plate 11, and movable through holes 15 are provided on both sides of the mounting bracket 14 in the vertical direction; the electric telescopic rod 2 is provided with a movable plug plate 21 perpendicular to the rod body, and the two ends of the movable plug plate 21 are respectively plugged into the two movable through holes 15, and the movable plug plate 21 can move in the vertical direction in the movable through hole 15 following the extension and retraction of the electric telescopic rod 2.

[0045] Furthermore, the width of the movable plug plate 21 is equal to the width of the movable through hole 15, so as to prevent the telescopic end of the electric telescopic rod 2 from shaking when it is raised or lowered, so that the gas cylinder tray 3 can be raised or lowered more stably.

[0046] In an example, Figure 1 and Figure 2 As shown, the lower end of the electric telescopic rod 2 located at the movable plug plate 21 is divided into a drooping connecting rod 22, and the drooping connecting rod 22 passes through the matching through hole 111 in the middle of the limiting plate 11 and is fixedly connected to the gas cylinder tray 3.

[0047] Specifically, the size of the matching through hole 111 provided in the middle of the limiting plate 11 matches the size of the drooping connecting rod 22 , thereby further improving the stability of the gas cylinder tray 3 when it is lifted up and down.

[0048] In an example, Figure 1 and Figure 2 As shown, the cooling device also includes a circulation pump 6 and a condenser 7. The cooling box 1, the circulation pump 6 and the condenser 7 are connected in sequence to form a ring using a circulation pipeline 5 to realize circulating refrigeration of the coolant.

[0049] Specifically, the circulating pump 6 provides the power for the circulating flow of the coolant, and the condenser 7 provides the circulating cold capacity for the coolant. In this way, the circulating pump 6 can make the coolant in a circulating flow state, which can better take away the heat of the gas cylinder and make the cooling efficiency higher; the condenser 7 can cool down the coolant with a high temperature, so that the coolant is kept at a low temperature, so that the coolant can continuously cool the gas cylinder, and the coolant can be recycled. The circulation pipeline 5 mainly serves the function of connection and transmission.

[0050] In an example, Figure 1 As shown, a first bottom plate 101 and a second bottom plate 102 are respectively provided on both sides of the cooling box 1 . The first bottom plate 101 is used for installing the circulation pump 6 , and the second bottom plate 102 is used for installing the condenser 7 .

[0051] Specifically, the circulation pipe 5 is fixedly mounted on the cooling box 1, and one side of the circulation pipe 5 is fixedly connected to the circulation pump 6, which is fixedly mounted on the first bottom plate 101, and the other side of the circulation pipe 5 is fixedly connected to the condenser 7, which is fixedly mounted on the second bottom plate 102. In this way, the structure of the cooling device can be made more compact.

[0052] In order to better understand the above embodiments, the working process of the cooling device of the present invention is further described below in conjunction with the accompanying drawings.

[0053] When cooling the gas cylinder, the gas cylinder is passed through the limiting through hole 12 so that the bottom of its lower end is inserted into the placement groove 31, and the gas cylinder at this time is inserted into the sponge wiping sleeve 4. Then the electric telescopic rod 2 is started to drive the movable plugboard 21 to move downward, and then the gas cylinder tray 3 can be driven to move downward, so that the gas cylinder can be driven to be inserted into the coolant for cooling. At the same time, under the action of the circulating pump 6, the coolant is in a state of circulation, so that the heat of the gas cylinder can be better taken away, so that the air in the gas cylinder can be quickly cooled down, and the cooling efficiency is higher. The coolant that takes away the heat is cooled by the condenser 7 and then circulated to the cooling box 1 again to achieve recycling, and the gas cylinder is continuously cooled to ensure the cooling effect. After the gas cylinder is cooled, the electric telescopic rod 2 is started to drive the gas cylinder to move upward, so that the coolant on the surface of the gas cylinder can be wiped clean under the action of the sponge wiping sleeve 4, without manual cleaning, which is very convenient, and the sponge wiping sleeve 4 is also relatively convenient and quick to replace.

[0054] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
