Description

Technical Field

[0001] This utility model relates to the field of fog cannons, and in particular to a range-extended fog cannon device. Background Technology

[0002] With increasing demands for energy conservation and emission reduction in ports, mines, and other locations, traditional stationary or diesel-powered fog cannons are gradually transitioning to new energy battery-powered systems. As the core power supply unit, the battery pack must provide continuous and safe power support to the fog cannon mechanism (such as a 37kW fan and water pump) under complex operating conditions including movement, vibration, and impact. However, existing battery pack designs in mobile devices suffer from the following key problems: mobile equipment is prone to collisions, tipping over, or severe vibrations during operation or transport. When the battery cells (such as lithium iron phosphate cells) are subjected to mechanical impact, it may lead to structural deformation, internal short circuits, or thermal runaway. Existing installation methods often use simple bolt fixation or rigid brackets, lacking targeted buffering and impact-resistant structures. For example, when the equipment is impacted or tipped over, the battery pack directly bears the impact, easily causing internal battery leakage, insulation damage, or even fire. Furthermore, traditional battery pack protection focuses on static scenarios and does not fully consider the multi-directional impact loads unique to mobile platforms. Utility Model Content

[0003] To address the lack of buffer protection in existing batteries, this invention proposes a range-extended fog cannon device, the technical solution of which is as follows: An extended-range fog cannon device is installed on a movable mounting surface, including a mounting base plate installed on the mounting surface. Above the mounting base plate, along the length of the mounting base plate, a fog cannon mechanism, a water tank, a battery pack, and a generator set are installed in sequence. Both the battery pack and the generator set can directly supply power to the fog cannon mechanism. The generator set can also charge the battery pack. The fog cannon mechanism can draw water from the water tank and spray water mist. The battery pack is fixed to the mounting base plate by a mounting mechanism; multiple anti-collision ribs are provided on the side of the battery pack, and the anti-collision ribs have cavities inside, and airbag components that can be triggered to expand are provided in the cavities.

[0004] Furthermore, the airbag assembly includes an airbag bag and a gas generator. The gas generator is provided with an air outlet and is electrically connected to a collision sensor. The airbag bag is connected to the air outlet of the gas generator. The collision sensor is used to activate the gas generator to inflate the airbag bag when a collision signal is detected.

[0005] Furthermore, the anti-collision rib is vertically fixed to the mounting base plate, and the cavity opened by the anti-collision rib opens to the side away from the battery pack. A cover plate is installed at the opening of the cavity, and the cover plate is used to close the cavity. After the airbag is inflated, the cover plate is pushed out of the cavity opening by the airbag.

[0006] Furthermore, a reinforcing rib is provided at the junction of the bottom end of the anti-collision rib and the mounting base plate.

[0007] Furthermore, the installation mechanism includes several rows of positioning holes opened along the width direction of the mounting base plate, which can install pre-fixing plates according to different battery pack specifications. The pre-fixing plate consists of a plate body and fixing ears provided on both sides of the plate body. The fixing ears are provided with a first through hole, the axis of the first through hole is parallel to the surface of the plate body, and the fixing ears can be fixed to the positioning holes by inserting bolts. After fixing, the pre-fixing plate is perpendicular to the mounting base plate and parallel to the side wall of the battery pack.

[0008] Furthermore, a plurality of triangular ribs are fixedly connected to the side of the pre-fixed plate away from the battery. The triangular ribs are perpendicular to the pre-fixed plate, and the two right-angled sides of the triangular ribs are respectively attached to the pre-fixed plate and the mounting base plate. A second through hole is opened on the triangular rib, the second through hole is perpendicular to the mounting base plate, and the first through hole on the pair of fixing ears and all the second through holes on the multiple triangular ribs can simultaneously correspond to multiple positioning holes.

[0009] The beneficial effects of this utility model are as follows: by detachably integrating the fog cannon mechanism, water tank, battery pack, and generator set onto the mounting base plate, and setting anti-collision ribs with built-in triggerable airbag components on the side of the battery pack, a safety protection system for the battery pack is constructed, reducing the risk of mechanical impact on the battery caused by accidents such as collisions and rollovers in complex working conditions; at the same time, this integrated design, combined with the range-extended power supply scheme, enables the equipment to achieve long-term continuous dust suppression operation through the battery pack when the generator set cannot provide power or there is no external power available.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments: like Figure 1 As shown, a range-extended fog cannon device is installed on a movable mounting surface, including a mounting base plate 1 installed on the mounting surface. Above the mounting base plate 1, along the length of the mounting base plate 1, a fog cannon mechanism 2, a water tank 3, a battery pack 4, and a generator set 5 are installed in sequence. Both the battery pack 4 and the generator set 5 can directly supply power to the fog cannon mechanism 2. The generator set 5 can also charge the battery pack 4. The fog cannon mechanism 2 can draw water from the water tank 3 and spray water mist. like Figure 1 , Figure 4 As shown, the battery pack 4 is fixed to the mounting base plate 1 by the mounting mechanism; the battery pack 4 is provided with a plurality of anti-collision ribs 6 on its side periphery, and the anti-collision ribs 6 are provided with cavities 61 inside, and airbag components that can be triggered to expand are provided in the cavities 61.

[0013] like Figure 2 , Figure 4 As shown, preferably, the airbag assembly includes an airbag bag 71 and a gas generator 72. The gas generator 72 is provided with an air outlet and is electrically connected to a collision sensor 73. The airbag bag 71 is connected to the air outlet of the gas generator 72. The collision sensor 73 is used to activate the gas generator 72 to inflate the airbag bag 71 when a collision signal is detected. This airbag assembly is monitored in real time by the collision sensor 73 to ensure an immediate response in the event of an accidental collision. After the airbag bag 71 is inflated, it forms a buffer layer, significantly reducing the impact force on the battery pack 4 and improving the safety and reliability of the overall device.

[0014] like Figure 3 , Figure 4 As shown, preferably, the anti-collision rib 6 is vertically fixed to the mounting base plate 1. The cavity 61 formed by the anti-collision rib 6 opens towards the side opposite to the battery pack 4. A cover plate 8 is installed at the opening of the cavity 61. The cover plate 8 is used to close the cavity 61, and after the airbag 71 is inflated, the cover plate 8 is pushed out of the opening of the cavity 61 by the airbag 71. The cover plate 8 is fixed to the edge of the opening of the cavity 61 by a breakable bolt. Under normal conditions, the bolt provides a strong connection. When the thrust generated by the inflation of the airbag 71 acts on the cover plate 8, the thrust is converted into a shearing force on the bolt. When the shearing force reaches a set threshold, the bolt will be neatly sheared at the preset weak groove, thereby releasing the cover plate 8. This method can precisely control the triggering force of the opening and has high reliability. However, since using a breakable bolt to achieve a similar function is a common operation in the prior art, it is not separately marked in the figure to keep the figure clear and concise. Only the principle is explained here.

[0015] It should be noted that the collision sensor 73 (usually an acceleration sensor or pressure sensor) continuously monitors the impact acceleration or pressure changes experienced by the range-extended fog cannon during movement or operation. When the impact force exceeds a preset safety threshold (e.g., equivalent to a collision or tipping at a specific angle), the collision sensor 73 immediately generates an electrical signal, which is transmitted in real time to the safety control unit (a microprocessor or dedicated control circuit). The control unit has a preset algorithm that quickly analyzes and judges the signal strength and duration to distinguish between everyday vibrations (such as equipment movement or road bumps) and real dangerous collisions, effectively preventing false triggering. Once the control unit determines a valid collision signal, it immediately sends a high-level trigger current to the gas generator 72 (the gas generator 72 is a commercially available gas generator containing solid propellant). Upon receiving the trigger current, its electric ignition head is ignited, rapidly initiating a chemical reaction and producing a large amount of harmless inert gas (such as nitrogen) in a very short time (milliseconds). The generated gas is rapidly filled into the airbag 71 through the air outlet, causing it to expand and push open the cover plate 8 of the cavity 61 of the anti-collision rib 6, forming an elastic buffer barrier around the battery pack 4. The above content is only a simple explanation of the working principle of the linkage between the collision sensor 73 and the gas generator 72.

[0016] As shown in Figure 3, preferably, a reinforcing rib 9 is provided at the junction of the bottom end of the anti-collision rib 6 and the mounting base plate 1. The reinforcing rib 9 effectively disperses the collision stress by increasing the connection area and structural rigidity, preventing the root of the anti-collision rib 6 from breaking, ensuring the stability of the protection system, maintaining reliable performance especially under harsh working conditions, and reducing fatigue damage caused by vibration.

[0017] like Figure 3 , Figure 4 As shown, preferably, the mounting mechanism includes several rows of positioning holes 101 on the mounting base plate 1 along the width direction of the mounting base plate 1. Pre-fixing plates can be installed according to different battery pack 4 specifications. The pre-fixing plate consists of a plate body 12 and fixing ears 13 provided on both sides of the plate body 12. Each fixing ear 13 has a first through hole 14, the axis of which is parallel to the surface of the plate body 12. Bolts can be inserted to fix the fixing ears 13 to the positioning holes 101. After fixing, the pre-fixing plate is perpendicular to the mounting base plate 1 and parallel to the side wall of the battery pack 4. The design of the positioning holes 101 and the pre-fixing plate allows for adjustable installation position of the battery pack 4, adapting to various battery specifications, simplifying replacement and maintenance processes. The fixing ears 13 and bolt connections ensure a secure fixation, reducing the risk of loosening due to vibration, and improving the versatility and installation efficiency of the device.

[0018] like Figure 3 , Figure 4As shown, preferably, a plurality of triangular ribs 15 are fixedly connected to the side of the pre-fixing plate opposite to the battery. The triangular ribs 15 are perpendicular to the pre-fixing plate, and the two right-angled sides of the triangular ribs 15 are respectively attached to the pre-fixing plate and the mounting base plate 1. A second through hole 16 is provided on the triangular rib 15. The second through hole 16 is perpendicular to the mounting base plate 1, and the first through hole 14 on the pair of fixing ears 13 and all the second through holes 16 on the plurality of triangular ribs 15 can simultaneously correspond to a plurality of positioning holes 101. The triangular ribs 15 significantly improve the bending and torsional resistance of the pre-fixing plate through the triangular stabilizing structure. The correspondence between the second through holes 16 and the positioning holes 101 allows for multi-point fixing, further distributing the load, ensuring that the battery pack 4 remains stable in a dynamic environment, reducing fatigue damage during long-term use, and enhancing the durability of the overall structure.

[0019] The premise of this technical solution is based on the overall structure of the range-extended fog cannon device: the generator set 5 usually includes an internal combustion engine (such as a diesel engine or a gasoline engine) and a generator, which is used to generate electrical energy to directly power the fog cannon mechanism 2 or to charge the battery pack 4; the battery pack 4 refers to a rechargeable lithium-ion battery pack 4 or other types of battery packs, which are used to store electrical energy and provide backup power for the fog cannon mechanism 2; the water tank 3 is connected to the fog cannon mechanism 2 through a water pump and pipes, and the water pump draws water from the water tank 3 and delivers it to the fog cannon; the fog cannon mechanism 2 has a spraying function, which can atomize water and spray it at high speed, and is mainly used for dust suppression, humidification, environmental cooling or fire dust suppression and other application scenarios. In order to make the attached drawings clear, the wires and water pipes between the components are not shown in the attached drawings, and the positions of the gas generator 72 and the collision sensor 73 are only shown.

[0020] The method of using this range-extended fog cannon device is as follows: start the generator set 5 or use the battery pack 4 to power the fog cannon mechanism 2, and the fog cannon mechanism 2 can draw water from the water tank 3 and spray water mist for operation; when a collision is detected, the anti-collision ribs 6 on the sides of the battery pack 4 will automatically trigger the airbag to expand and open the cover plate 8 to form a buffer layer to ensure battery safety.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
