Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a multi-channel nitrogen fire extinguishing device. Background Art

[0002] Gas fire extinguishing usually refers to a fire extinguishing system that uses a gaseous fire extinguishing agent to extinguish fires at room temperature and atmospheric pressure. Among them, the more common ones are inert gas fire extinguishing systems such as nitrogen. Nitrogen can absorb the heat of the flame and dilute the oxygen, and reduce the contact area between the flame and the combustible material to an extremely low level, thereby achieving the purpose of extinguishing the fire. The most important reason is that the site after nitrogen fire extinguishing is non-toxic and can be used in special environments.

[0003] A multi-channel nitrogen fire extinguishing device requires a sufficient nitrogen source when extinguishing a fire. Therefore, multiple gas cylinders are usually arranged at the end of the fire extinguishing device to meet the fire extinguishing needs. However, existing multi-channel nitrogen fire extinguishers usually place multiple gas cylinders side by side on a fixed frame, and in order to minimize the space occupied by the gas cylinders, the distance between the gas cylinders is usually set to be small, so that the used gas cylinders are prone to collision with adjacent gas cylinders when replaced, which is not conducive to the replacement of the gas cylinders; in addition, when the gas cylinders in the existing multi-channel nitrogen fire extinguishing device are about to run out, it is usually necessary to check the pressure gauge on the gas cylinder, and because the nitrogen fire extinguishing device can adjust the pressure of the nitrogen filling pipeline at any time, the pressure value displayed on the gas cylinder will change due to the change of the pipeline pressure, which is not conducive to the operator to promptly find the gas cylinder that is about to run out and replace it. Utility Model Content

[0011] Preferably, the top end of the spring is fixedly connected to the bottom end of the plate, the bottom end of the spring is fixedly connected to the bottom of the inner side of the vertical tube, and the plate is movably embedded in the vertical tube via the spring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The multi-channel nitrogen fire extinguishing device, through the rotating plate, vertical cylinder, vertical column, ring and horizontal tube, allows the gas cylinders at the end of the device to be placed around the vertical column with the vertical column as the center of the circle, and under the limit of the vertical cylinder, the gas cylinders can be separated by a sufficient distance, so that the gas cylinders can be placed at a large distance without occupying too much space, thereby reducing the probability of collision when replacing the gas cylinders, which is more conducive to the replacement of the gas cylinders.

[0014] 2. The multi-channel nitrogen fire extinguishing device uses a flat plate, a spring, a waistline and a clamping ring so that the weight difference of the gas cylinder on the fire extinguishing device before and after use can be reflected through the force exerted by the gravity of the gas cylinder on the flat plate, which causes the flat plate to squeeze the spring and causes the spring to deform, so that the used gas cylinder can be lifted up by the flat plate, and the change in the relative position between the waistline and the clamping ring can more intuitively reflect the gas cylinder that is about to be used up, so that the operator can find the gas cylinder that is about to be used up in time and replace it.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4As shown, the multi-channel nitrogen fire extinguishing device of this embodiment includes a base 14, a vertical column 8 is fixedly connected to the middle of the base 14, a block 9 is engaged with the top of the vertical column 8, a swivel joint 4 is installed on the top of the block 9, a gas pipe 5 is movably penetrated through the top of the swivel joint 4, four horizontal tubes 2 are penetrated through the outer wall of the swivel joint 4, a ring 1 is fixedly connected to one end of the horizontal tube 2, a vertical tube 3 is penetrated in the middle of the horizontal tube 2, a rotating plate 13 is provided on the top of the base 14, four vertical cylinders 12 are fixedly connected to the top of the rotating plate 13, a flat plate 15 is provided inside the vertical cylinder 12, a spring 16 is provided at the bottom of the flat plate 15, a gas cylinder 7 is movably connected to the inner side of the vertical cylinder 12, a waistline 11 is fixedly connected to the outer wall of the gas cylinder 7, and a clamping ring 10 is provided on the outer side of the gas cylinder 7.

[0024] Specifically, the interior of the base 14 is a hollow structure, so that the inner ratchet 18 and the ratchet 17 can have enough space to rotate in the base 14, thereby facilitating the rotation of the rotating plate 13 along the base 14. The function of the vertical column 8 is to support the top circular ring 1 and the horizontal tube 2 and other structures, thereby increasing the stability of the above structure. The block 9 can enable the rotating joint 4 of the pipeline to be mounted on the vertical column 8 and supported by the vertical column 8. The function of the rotating joint 4 is to enable the horizontal tube 2 to be connected to the gas pipe 5 in a movable manner, so that the horizontal tube 2 can rotate with the rotation of the gas cylinder 7, thereby reducing the interference caused by the rotation of the gas cylinder. The horizontal tube 2 enables the gas cylinder 7 to be connected to the pipeline for conveying nitrogen. The circular ring 1 can facilitate the operator to rotate the horizontal tube 2, so that the horizontal tube 2 can rotate accordingly with the rotation of the gas cylinder 7, so that the gas cylinder 7 can always maintain a connection with the corresponding horizontal tube 2. The inner diameter is adapted to the outer diameter of the bottom of the gas cylinder 7, so that the gas cylinder 7 can be smoothly placed in the vertical tube 12 and connected with the rotating plate 13. The flat plate 15 is a circular plate, and its outer diameter is adapted to the inner diameter of the vertical tube 12, so that the flat plate 15 can slide smoothly in the vertical tube 12, and the spring 16 can drive the flat plate 15 to slide up and down in the vertical tube 12 according to its own elastic deformation, thereby realizing the up and down sliding of the gas cylinder 7 in the vertical tube 12. The waistline 11 is a marking line on the outside of the gas cylinder 7, and its color is significantly different from the color of the bottle body, which is convenient for the user to quickly confirm the position of the waistline 11. The function of the clamping ring 10 is to stabilize the middle part of the gas cylinder 7, thereby increasing the stability of the gas cylinder 7 placed on the device, and at the same time, it can be used as a comparison reference after the position of the waistline 11 on the gas cylinder 7 is changed, so that it is convenient for the operator to promptly find the gas cylinder 7 that is about to run out, which is conducive to timely replacement of the new gas cylinder 7.

[0025] Furthermore, a connecting hose 6 is sleeved on the top end of the gas cylinder 7, and the connecting hose 6 is movably threadedly connected to the vertical pipe 3. The function of the connecting hose 6 is to enable the gas cylinder 7 to communicate with the vertical pipe 3 and the interior of the horizontal pipe 2, so that the nitrogen in the gas cylinder 7 can smoothly enter the interior of the horizontal pipe 2, thereby providing a nitrogen source for the fire extinguishing device.

[0026] Furthermore, the interior of the gas pipe 5 is communicated with the interior of the cross pipe 2 through the rotary joint 4, and the gas pipe 5 is communicated with the interior of the gas storage bottle 7 through the cross pipe 2, so that the nitrogen entering the cross pipe 2 can smoothly enter the gas pipe 5 of the fire extinguishing pipeline through the rotary joint 4, so that the nitrogen can reach the fire extinguishing area along the gas pipe 5, thereby realizing the nitrogen filling of the fire extinguishing area.

[0027] Furthermore, the clamping ring 10 is fixedly connected to the vertical column 8, and a notch is opened on one side wall of the clamping ring 10. The clamping ring 10 is movably connected to the gas cylinder 7 through the notch. The inner diameter of the clamping ring 10 is adapted to the outer diameter of the middle part of the gas cylinder 7, so that the gas cylinder 7 can be stably placed in the vertical cylinder 12 on the rotating plate 13.

[0028] Furthermore, an inner ratchet 18 is fixedly connected to the bottom end of the rotating plate 13, and a ratchet 17 is movably embedded in the inner side of the base 14. The rotating plate 13 is rotatably connected to the base 14 through the inner ratchet 18 and the ratchet 17. When the rotating plate 13 rotates at the top of the base 14, the ratchet 17 will engage with the inner ratchet 18. When the rotating plate 13 stops rotating, the rotating plate 13 will remain stationary due to the engagement of the ratchet 17 with the ratchet, thereby facilitating the removal of the gas cylinder 7 from the vertical cylinder 12.

[0029] Furthermore, the gas cylinder 7 is movably connected to the flat plate 15 via the vertical tube 12, and the weight of the gas cylinder 7 that is almost used up will become lighter, so that the force exerted by the gas cylinder 7 on the flat plate 15 becomes smaller, and the deformation of the spring 16 at the bottom of the flat plate 15 is reduced, so that the gas cylinder 7 can be lifted up by the spring 16 in the vertical tube 12, thereby realizing the relative change of the position of the waistline 11 on the gas cylinder 7 and the clamping ring 10 on the vertical column 8.

[0030] Furthermore, the top end of the spring 16 is fixedly connected to the bottom end of the plate 15, and the bottom end of the spring 16 is fixedly connected to the bottom of the inner side of the vertical tube 12. The plate 15 is movably embedded in the vertical tube 12 through the spring 16. The initial state of the spring 16 is the original length, so that the top of the plate 15 is close to the top of the vertical tube 12. After the fully-filled gas cylinder 7 is placed in it, it will be compressed to the limit state, so that the gas cylinder 7 can move up and down in the vertical tube 12 through the change of weight, so that the operator can find the gas cylinder 7 that is about to run out in time.

[0031] The method of using this embodiment is as follows: when using the multi-channel nitrogen fire extinguishing device, it is necessary to first place the full gas cylinder 7 in the vertical tube 12 of the rotating plate 13, so that the bottom of the gas cylinder 7 contacts the top of the flat plate 15, and then the flat plate 15 will be subjected to the force generated by the gravity of the gas cylinder 7, squeezing the spring 16 at the bottom of the flat plate 15, so that the spring 16 is compressed to the limit state, and then the connecting hose 6 at the top of the gas cylinder 7 can be connected to the vertical tube 3 in the middle of the horizontal tube 2, so that the nitrogen in the gas cylinder 7 can enter the vertical tube 3 and the horizontal tube 2 through the connecting hose 6. After completing the placement and connection of the gas cylinder 7, the fire extinguishing device can be used. After the device has been used for a period of time, as the nitrogen in the gas cylinder 7 decreases, the weight of the gas cylinder 7 will become lighter, so that the force on the flat plate 15 becomes smaller, so that the flat plate 15 exerts less pressure on the spring 16 The effect becomes smaller, so that the elastic deformation of the spring 16 becomes smaller, which causes the flat plate 15 to be pushed up, so that the flat plate 15 pushes the gas cylinder 7 to move up along the vertical tube 12, so that the waistline 11 on the gas cylinder 7 that originally coincides with the clamping ring 10 will move to above the clamping ring 10. At this time, the operator can find the gas cylinder 7 that is about to run out according to the change in the relative position of the waistline 11 and the clamping ring 10, so that the nitrogen can be replenished in time, and when a new gas cylinder 7 needs to be replaced, the rotating plate 13 and the top ring 1 can be rotated at the same time, so that the gas cylinder 7 rotates with the rotating plate 13 to a position convenient for the operator to operate, and then the rotating plate 13 is stopped. At this time, the rotating plate 13 will remain stationary under the action of the inner ratchet 18 and the ratchet 17, and then the empty gas cylinder 7 can be taken out from the top of the vertical tube 12, and finally replaced with a new gas cylinder 7 filled with nitrogen.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
