Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to a granular fire extinguishing material conveying device. Background Art

[0002] Existing fire extinguishing systems use conveyor belts to transport granular fire extinguishing materials. Conveyor belts are only suitable for transporting whole packages or bags of materials from one location to another, saving labor. However, conveyor belts are generally fixed in position, making them difficult to move and inflexible. Therefore, unless the fire is located directly at the end of the conveyor belt, it is impossible to transport fire extinguishing materials for extinguishing the fire.

[0003] For an existing technical solution of using a conveyor belt to deliver fire extinguishing materials, please refer to the Chinese utility model patent with publication number CN214074810U, entitled A Self-Taking Soil-Throwing Forest Soil-Throwing Fire Fighting Vehicle, which includes a vehicle body, a traveling assembly being provided at the bottom of the vehicle body, a rotary tillage device being provided at the front end of the vehicle body and a soil crushing mechanism and a soil-throwing conveying frame being provided at the rear end in sequence; wherein the soil-transferring conveyor belt is provided on the vehicle body, wherein one end thereof is close to the root-tillage device and the other end is close to the soil inlet of the soil crushing mechanism, wherein the feeding end of the soil-throwing conveying frame is located directly below the soil outlet of the soil crushing mechanism.

[0004] In this prior art, although the conveyor belt is installed on the vehicle body so that the conveyor belt can be moved, its fire extinguishing material, i.e., soil, needs to be taken on-site and in real time. Moreover, this type of fire extinguishing device is only suitable for outdoor use and is not suitable for places such as production workshops.

[0005] If a fire extinguisher that is easy to move is used, such as a dry powder fire extinguisher, this type of fire extinguishing equipment can be found in the Chinese utility model patent with publication number CN220989473U, entitled "A dry powder fire extinguishing device," which includes a cylinder, a connecting seat provided on the top of the cylinder, a connecting head provided on the top of the connecting seat, an observation component provided on the side of the connecting head, and a pressing component provided on the top of the connecting head. A connecting line is used to connect the alarm to the pressure gauge. When the pointer of the pressure gauge points to the red failure area, the information is transmitted to the alarm, and the alarm sounds a reminder that the dry powder fire extinguisher has failed, allowing the user to replace the fire extinguisher more promptly. The end of the movable rod is inserted into the groove of the required height on the fixing ring and fixed, so that the pressing hand is always in a downward pressing state, so that the dry powder fire extinguisher can automatically spray dry powder without manual pressure. In addition, the end of the movable rod is inserted into the grooves of different heights to adjust the downward pressure of the pressing hand, thereby adjusting the spray rate.

[0006] The tanks of these fire extinguishers are all high-pressure containers, meaning they release the fire extinguishing material stored within them through a high-pressure medium stored within the tank. High-pressure tanks are subject to high safety standards, both in manufacturing and routine maintenance. Furthermore, these fire extinguishers cannot add fire extinguishing material to the tank during the firefighting process. Once the fire extinguishing material and high-pressure medium within the tank are depleted, the fire extinguisher becomes ineffective. Furthermore, these fire extinguishers cannot transfer fire extinguishing material between different fire extinguishers, effectively preventing them from transporting fire extinguishing material. Utility Model Content

[0007] In order to solve the inconvenience caused by the high-pressure tank body of the existing fire extinguisher, and solve the problem that fire extinguishing material cannot be added to the tank body and the fire extinguishing material cannot be transported, the purpose of the utility model is to provide a granular fire extinguishing material transporting device.

When the high-pressure gas source is connected to the feeding mechanism, the high-pressure gas source is used to blow the granular fire extinguishing material into the feeding mechanism.

[0012] As an optional technical solution, the feeding mechanism includes a collecting hopper installed at the bottom of the storage barrel, the collecting hopper is connected to the discharge port of the storage barrel; the collecting hopper is also provided with a feeding port;

[0013] The feeding mechanism further includes a blowing assembly mounted on the collecting hopper, the blowing assembly corresponding to the feeding port, and the blowing assembly being detachably connected to a high-pressure gas source; when the blowing assembly is connected to the high-pressure gas source, the high-pressure gas source blows the granular fire extinguishing material falling into the collecting hopper into the feeding port;

[0014] The feeding mechanism also includes a pneumatic conveyor installed at the feeding port, which can be detachably connected to the high-pressure air source; when the pneumatic conveyor is connected to the high-pressure air source, the pneumatic conveyor is used to blow the granular fire extinguishing material.

[0015] Optionally, the feed port is equipped with a discharge pipe extending into the collecting hopper, and the angle between the axis of the discharge pipe and the discharge port is 70 to 90 degrees.

[0016] Optionally, the inlet end of the discharge pipe extends to below the discharge port, and the inlet end of the discharge pipe is provided with a cutout facing the discharge port.

[0041] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0042] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology. They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance. Any modification of the structure, change in the proportion relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present utility model without affecting the efficacy and purpose of the present invention. At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0043] In one embodiment, if Figure 1 As shown, the present invention proposes a granular fire extinguishing material conveying device, comprising a storage barrel 1 and a feeding mechanism, wherein the storage barrel 1 is provided with an internal space for storing granular fire extinguishing materials. It should be noted that in this embodiment, the internal space of the storage barrel 1 is at normal pressure. Normal pressure here generally refers to one atmosphere, but due to differences in geographical location, altitude, temperature, etc., the actual local atmospheric pressure is not equal to the standard atmospheric pressure in each place. Normal pressure here refers to the atmospheric pressure of the operating environment of this conveying device, that is, the air pressure of the internal space of the storage barrel 1 is the same as the air pressure of the operating environment outside the storage barrel 1. At this time, there is no high-pressure cavity for storing high-pressure medium in the storage barrel 1, and this storage barrel 1 is not a high-pressure container.

[0044] The feeding mechanism is installed at the bottom of the storage barrel 1. When the feeding mechanism is installed at the bottom of the storage barrel 1, the granular fire extinguishing material will automatically fall into the feeding mechanism, and then be transported to the fire source by the feeding mechanism to extinguish the fire, or be transported to other storage barrels 1 by the feeding mechanism, or be transported to other locations by the feeding mechanism.

[0045] Specifically, in this embodiment, the feeding mechanism is removably connected to a high-pressure gas source. This removable connection means that the feeding mechanism is only connected to the high-pressure gas source when the granular fire-extinguishing material in the storage barrel 1 is needed to extinguish a fire or to transport it elsewhere. The high-pressure gas source then blows the granular fire-extinguishing material into the feeding mechanism to the desired location. When the feeding mechanism is not needed, the feeding mechanism does not need to be connected to the high-pressure gas source. In other words, by being removably connected to an external high-pressure gas source, the storage barrel 1 of this conveying device is no longer a high-pressure container. Furthermore, since this conveying device is intended for use in places such as production workshops, obtaining a high-pressure gas source is relatively convenient.

[0046] Because the storage barrel 1 in this embodiment is not a high-pressure container, a loading port can be provided at the top of the barrel 1, allowing the interior of the barrel 1 to communicate directly with the surrounding environment. When this feeding mechanism delivers granular fire-extinguishing material to a fire source for extinguishing, or when delivering it to another location, the interior of the barrel can be replenished with fire-extinguishing material through the loading port. Furthermore, fire-extinguishing material in a barrel 1 can be transferred to the loading port of another barrel 1, enabling the transfer of fire-extinguishing material between different barrels 1.

[0047] In one embodiment, a cylinder cover can be installed at the loading port. The cylinder cover can be opened and closed, for example, by a hinge or threaded connection to the storage barrel 1. When it is necessary to add fire extinguishing material to the cylinder space, the cylinder cover can be opened. When it is not necessary to add fire extinguishing material to the cylinder space, the cylinder cover can be closed to prevent debris from falling into the cylinder space. It should be noted that even though the cylinder cover is installed, the cylinder space remains at normal pressure.

[0048] All granular fire extinguishing materials in the prior art are suitable for the present conveying device. It should be noted that such granular fire extinguishing materials need to be able to be stored under normal pressure.

[0049] In one embodiment, the feeding mechanism comprises a hopper 2 mounted at the bottom of the storage barrel 1. The hopper 2 is in communication with the discharge port 103 of the storage barrel 1. The granular fire extinguishing material stored in the barrel automatically falls into the hopper 2 through the discharge port 103 due to gravity.

[0050] The feeding mechanism also includes a blowing assembly mounted on the hopper 2. This blowing assembly corresponds to a feed port provided on the hopper 2. The blowing assembly is removably connected to a high-pressure air source. This removable connection means that the high-pressure air source is connected to the blowing assembly only when the blowing assembly is needed to blow the material. When the feeding mechanism is not in use, it does not need to be connected to the high-pressure air source. When the blowing assembly is connected to the high-pressure air source, the high-pressure air source blows the granular fire-extinguishing material that has fallen into the hopper 2 into the feed port.

[0051] The feeding mechanism also includes a pneumatic conveyor 4 installed at the feeding port. The pneumatic conveyor 4 is relatively mature in the prior art and will not be described in detail here. Its structure can be found in the Chinese utility model patent with publication number CN206939903U, entitled A Pneumatic Conveyor. Similarly, this pneumatic conveyor 4 can be detachably connected to a high-pressure air source. When it is necessary to blow granular fire extinguishing materials to the fire source to extinguish the fire, or blow them to other locations. Connect the high-pressure air source to the blowing assembly, and connect the pneumatic conveyor 4 to the high-pressure air source. The granular fire extinguishing materials that fall into the collecting hopper 2 are sucked into the feeding port and then enter the channel of the pneumatic conveyor 4. The pneumatic conveyor 4 then blows the granular fire extinguishing materials in the channel to the fire source or other locations.

[0052] In one embodiment, the feed port is equipped with a discharge pipe 3 extending into the aggregate hopper 2. In this embodiment, in order to allow the granular fire extinguishing material in the space inside the cylinder to fall directly into the aggregate hopper 2 due to gravity, the discharge port 103 is vertically downward. In this embodiment, the discharge port 103 is circular, and its axis is vertical. The angle between the axis of the discharge pipe 3 and the discharge port 103 is 70 to 90 degrees, that is, the angle between the axis of the discharge pipe 3 and the axis of the discharge port 103 is 70 to 90 degrees, such as 70 degrees, 73 degrees, 85 degrees, or 90 degrees. By installing the discharge pipe 3 extending into the aggregate hopper 2, the fire extinguishing material in the aggregate hopper 2 can be more easily entered into the feed port, and then blown by the pneumatic conveyor 4. The angle between the axis of the discharge pipe 3 and the discharge port 103 is 70 to 90 degrees, that is, the discharge pipe 3 is perpendicular to the discharge port 103, or the discharge pipe 3 is arranged slightly upward to prevent the fire extinguishing material from leaking out of the feed port when it is not needed. If the discharge pipe 3 is arranged downward, the fire extinguishing material may leak out of the feed port when it is not needed.

[0053] To facilitate the blowing of granular fire extinguishing material into the feed port by the blowing assembly when it is needed, the inlet end of the discharge pipe 3 is extended below the discharge port 103, and a notch 301 is provided at the inlet end of the discharge pipe 3 facing the discharge port 103. This allows the granular fire extinguishing material falling from the discharge port 103 to fall directly into the notch 301 of the discharge pipe 3, thereby being easily blown to the feed port by the blowing assembly.

[0054] The pneumatic conveyor 4 is mounted on the outlet end of the discharge pipe 3, and a hose is connected to the outlet of the pneumatic conveyor 4. By installing the hose (not shown in the figure), the hose can be dragged freely, with good flexibility. The hose can be dragged to the fire point for precise fire extinguishing, or it can be dragged to other places where fire extinguishing materials need to be transported, such as for refueling.

[0055] In one embodiment, the blowing assembly comprises a feed pipe 5, which is removably connected to a high-pressure gas source. To facilitate the blowing assembly in blowing granular fire-extinguishing material into the discharge pipe 3, the feed pipe 5 is positioned to meet the following requirements: On a plane perpendicular to the axis of the feed pipe 5, the projection of the feed pipe 5 on this plane lies within the projection of the inlet end of the discharge pipe 3 on this plane. This ensures that the high-pressure gas ejected from the orifice of the feed pipe 5 is directly aimed at the inlet end of the discharge pipe 3, thereby maximizing the amount of high-pressure gas blown into the discharge pipe 3. This facilitates the blowing of fire-extinguishing material into the discharge pipe 3 and, subsequently, into the passageway of the pneumatic conveyor 4.

[0056] In order to allow all the granular fire extinguishing materials in the storage barrel 1 to enter the collecting hopper 2, the bottom of the storage barrel 1 is made into a funnel 102, and the discharge port 103 is located at the end of the funnel 102. In this way, the granular fire extinguishing materials stored in the barrel 1 can be gathered in the funnel 102 and then all enter the collecting hopper 2 from the discharge port 103.

[0057] The collecting hopper 2 is provided with a clamping groove 201 , which is sealed and communicated with the discharge port 103 , thereby preventing the granular fire extinguishing material from leaking from the connection between the collecting hopper 2 and the discharge port 103 .

[0058] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
