Description

Technical Field

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

[0002] Gas detectors are devices used to detect the concentration of flammable or toxic gases in the air. They are widely used in the fields of petrochemicals, coal mines, and city gas. In order to ensure the accuracy and reliability of the detectors, it is necessary to carry standard gas cylinders with the same gas as the detector to calibrate and calibrate the detectors regularly.

[0003] A standard gas cylinder is a pressure-bearing device. The medium it contains is generally flammable, explosive, toxic, and highly corrosive. The operating environment is relatively complex and harsh, and it is inconvenient to transport and carry. At present, backpacks and suitcases are generally used to transport and carry gas cylinders. During transportation, the gas cylinders are prone to bumps, collisions, and vibrations in the vehicle, which will cause damage to the cylinder body and loose and malfunctioning cylinder valves, leading to gas leakage or cylinder explosion. During the carrying process, the gas cylinders are also prone to tipping, bumping, and shaking, and the gas is also prone to leakage, which is also dangerous.

[0004] In order to reduce bumps and collisions, using hard boxes to transport and carry gas cylinders can reduce certain risks. However, it is impossible to monitor in real time whether the gas cylinders are in a safe and controllable state during transportation and carrying. The leakage of high-concentration gas after shock cannot be discovered in time, which will cause personal poisoning and environmental pollution. Utility Model Content

[0005] The utility model aims to provide a portable gas cylinder storage box to solve the problem that gas leakage of standard gas cylinders used for petrochemical industry, coal mine and gas calibration cannot be found in time during transportation and carrying.

[0006] In order to achieve the above-mentioned purpose, the portable gas cylinder storage box of the utility model adopts the following technical solutions:

[0008] Beneficial effects: The portable gas cylinder storage box of the utility model is an improved invention. Since the density of standard gas in standard gas cylinders used for petrochemical, coal mining and gas calibration is generally greater than that of air, when the gas in the gas cylinder leaks, the gas will be deposited in the lower part of the box. The utility model places the gas cylinder at the bottom of the box, and arranges a gas sensing device on the box cover. The gas sensing device includes an alarm and a gas sensor connected to the alarm, and the gas sensor is arranged to protrude from the box cover to a set height, so that the distance between the gas sensor and the box bottom satisfies that when the gas leaks, the gas sensor can detect the leaking gas in the lower part of the box in time. When the gas in the gas cylinder leaks, the gas sensor will quickly sense it, and the alarm will sound an alarm, thereby achieving the effect of real-time monitoring, thereby solving the problem that the gas leakage of standard gas cylinders used for petrochemical, coal mining and gas calibration cannot be detected in time during transportation and carrying.

[0009] Furthermore, a handle is provided on the front side of the box body, and the gas sensor is arranged on the box cover close to the rear side of the box body.

[0010] Furthermore, the box body has a bottle mouth corresponding end corresponding to the bottle mouth of the gas cylinder and a bottle bottom corresponding end corresponding to the bottle bottom of the gas cylinder in the left and right directions, and the gas sensor is arranged close to the bottle mouth corresponding end.

DETAILED DESCRIPTION

[0022] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0023] In the prior art, a hard box is used to transport and carry gas cylinders, which can reduce bumps and collisions. However, it is impossible to monitor in real time whether the gas cylinders are in a safe and controllable state during transportation and carrying. The leakage of high-concentration gas after shock cannot be discovered in time, which will cause personnel poisoning and environmental pollution. In view of the above problems, the utility model designs a portable gas cylinder storage box. When the gas in the gas cylinder leaks, if the density of the standard gas is greater than that of air, the leaked gas will accumulate at the bottom of the box. If the density of the standard gas is less than that of air, the leaked gas will float above the air in the upper part of the box. The density of the standard gas in the standard gas cylinder used for petrochemical, coal mining and gas calibration is generally greater than that of air. The core concept of the utility model is to use this feature to place the gas cylinder at the bottom of the box, set a gas sensing device on the box cover, and set the sensing part of the gas sensing device to protrude inward from the box cover and have a set height, so that it can detect the gas leaking from the lower part of the box in time.

[0024] Based on the above invention concept, Figure 2 As shown, a portable gas cylinder storage box of the utility model comprises a box body 7 and a box cover 8. The bottom of the box body 7 is used to place the gas cylinder. The box cover 8 is provided with a gas sensing device 3. The gas sensing device 3 comprises an alarm and a gas sensor 302 connected to the alarm. The gas sensor 302 protrudes toward the bottom of the box from the box cover 8 to set a height so that the distance between the gas sensor 302 and the bottom of the box satisfies that when gas leaks, the gas sensor 302 can detect the leaked gas at the lower part of the box in time.

[0025] Among the above components, Figure 1In the embodiment shown, the storage box is set to a rectangular parallelepiped shape in consideration of portability. In some other embodiments, the storage box can also be set to a cube or an ellipse. The storage box includes a box body 7 and a box cover 8. The box body 7 and the box cover 8 are connected by hinge bearings and can be opened and closed at 180°. In order to prevent the box cover 8 from opening during transportation and carrying of the gas cylinder, the box body 7 and the box cover 8 are opened and closed by a lock 9. The lock 9 is a snap lock for easy opening and closing. In some other embodiments, the lock 5 can also be set to an electronic lock, a key lock, etc. A seal is provided at the connection between the box body 7 and the box cover 8 to prevent the leakage of toxic gases from endangering the staff. In consideration of convenient carrying, a handle 10 is provided on the front side of the box body 7. The handle 10 is a crescent-shaped handle. In some other embodiments, it can also be set to a straight-line handle.

[0026] In such Figure 2 In the illustrated embodiment, a partition 4 is provided in the box body 7, the partition extends in the left-right direction and separates two gas cylinder placement positions 5 in the box body 7, the box body 7 has a bottle mouth corresponding end 701 corresponding to the bottle mouth of the gas cylinder and a bottle bottom corresponding end 702 corresponding to the bottle bottom of the gas cylinder in the left-right direction, the partition 4 can provide additional support and fixation for the gas cylinder, limit the relative displacement of the gas cylinder during transportation and storage, reduce collision and shaking, the size of the gas cylinder placement position 5 is adapted to the size of the gas cylinder, the partition 4 is provided in the middle position of the box body 7, the gas cylinder placement position 5 can store gas cylinders of the same specifications and sizes, in some other embodiments, the partition 4 may not be provided in the middle position of the bottom of the box body 7, and its position may be determined specifically according to the size of the gas cylinder, and more than two gas cylinder placement positions 5 may also be provided. Considering the particularity of the gas cylinder, the gas cylinder placement position 5 is made of foam material, which has good shock absorption performance, can reduce the impact and vibration of the gas cylinder during transportation and storage to a certain extent, and protect the gas cylinder from damage. In some other embodiments, the material of the gas cylinder placement position 5 can also be made of plastic, stainless steel, fiberglass and other materials with good shock absorption. The partition 4 is arranged at intervals with the corresponding end of the bottle mouth. The partition 4 is provided at one end close to the corresponding end of the bottle mouth with a connecting port 6 connecting the gas cylinder installation positions on both sides thereof. The connecting port 6 is formed by the interval between the two, and the connecting port 6 allows the gas to pass smoothly and reach the detection point in time.

[0027] In such Figure 2 In the illustrated embodiment, a gas cylinder fixing assembly 2 is provided in the gas cylinder placement position 5 for fixing the gas cylinder placed therein. The gas cylinder fixing assembly 2 comprises a gas cylinder strap fixedly connected to the box body 7. The gas cylinder strap is preferably a fixed elastic band. The fixed elastic band has strong anti-slip properties and stability, can effectively clamp the gas cylinder to prevent slipping, and the length of the elastic band can be adjusted automatically to adapt to gas cylinders of different sizes. In some other embodiments, the gas cylinder strap can also be set to a clamp-type locking ring, a fixed locking rope, etc.

[0028] In such Figure 1 , Figure 2 and Figure 3 In the embodiment shown, considering that the leaked gas can be detected in time and the concentration of the leaked gas can be conveniently read, the gas sensing device 3 is arranged on the box cover 8, close to the rear side of the box body 7, and close to the connecting port 6 at the corresponding end of the bottle mouth. The gas sensing device 3 is an integrated type, which can quickly and accurately detect the leakage of gas, and is easy to install, reducing the failure caused by poor connection and mismatch of components, and is easy to maintain. In some other embodiments, the gas sensing device 3 can also be set as a non-integrated type. The gas sensing device 3 includes a display 301, an alarm and a gas sensor 302. The gas sensor 302 is connected to the alarm and is embedded in the inner side of the box cover 8. The bottom is a connected space, which protrudes from the box cover 8 to the bottom of the box to set a height. For example, the height of its end from the bottom of the box is 5-10 cm. The distance between the gas sensor 302 and the bottom of the box satisfies that when the density of the leaked gas is greater than the density of air and the gas is deposited at the bottom of the box body 7, the gas sensor 302 can also detect the leaked gas in time. The alarm is preferably an audible and visual alarm, which enables the staff to find the alarm signal in time and deal with it, reducing safety hazards. In some other embodiments, the alarm can also be a sound alarm. The alarm and the display 301 are located outside the box cover 8, which is convenient for timely finding the gas leakage alarm and reading the concentration of the gas in the box. The display 301 is connected to the gas sensor. When the gas cylinder in the box 7 leaks, the gas sensor 302 reacts electrochemically with the leaked gas, converts the electrical signal into an analog signal, and displays the gas concentration on the display 301. The audible and visual alarm also sends out an audible and visual alarm. Considering the overall beauty of the box 1 and protecting the display from damage during transportation and carrying, the display 301 is flush with the outer surface of the box cover 9. In some other embodiments, the display 301 can also be set to protrude from the box cover 8.

[0029] When using the portable gas cylinder storage box, the gas cylinder to be transported or carried is placed in the gas cylinder placement position 5, and the gas cylinder fixing component 2 is adjusted according to the size of the gas cylinder to completely fix the gas cylinder, and then the box body 1 is locked. If the gas in the gas cylinder leaks during the transportation and carrying of the gas cylinder, the gas sensor 302 will quickly sense the leaked gas and display the gas concentration on the display 301, and the sound and light alarm will send out a sound and light alarm to remind the operator to take timely measures.
