Description

Technical Field

[0001] The present invention relates to a hydraulic drilling spray gun for container fire extinguishing, and particularly to a hydraulic drilling spray gun for container fire extinguishing that can automatically drill holes in a container door by using water pressure to form fire extinguishing holes and then spray water to extinguish the fire when a fire occurs in the container, and can quickly extinguish the fire without being restricted by the height of multi-layer stacked containers through vertical height adjustment. Background Art

[0002] Recently, in order to meet the needs of maritime logistics transportation, container ships are developing towards super-large scale. Moreover, due to the characteristics that the goods loaded on the containers are put into the interior of the containers and sealed and non-disclosed, fires may occur in the containers themselves during maritime transportation independently of the hull part due to reasons such as impact, friction, static electricity, spontaneous combustion, mixed contact ignition of internal substances, and exothermic reactions of metallic substances with rainwater, moisture, and other moisture.

[0003] For fires occurring inside containers, according to the heat release rate (HRR) based on the material characteristics, the heat and smoke released during a fire will also vary. Furthermore, due to the structural characteristic of occurring inside the container, it is impossible to detect the fire, and crew members, fireboats, and fire aircraft cannot inject foam, seawater, and powder agents for fire extinguishing into the container. Therefore, once a fire occurs, it will last for a long time. For fires caused by high-heat-generating chemical substances and industrial products, etc., the heat released during the fire will be transmitted chain by chain to adjacent containers through conduction, convection, and radiation phenomena, thus becoming the main cause of expanding losses.

[0004] To extinguish the above-mentioned fires, currently, it is necessary for operators to drill holes in the container door with a hammer and then insert a spray gun for water spraying into the holes to extinguish the fire. However, during the process of drilling holes in the container door made of steel, it takes a lot of time and labor, and since the operator needs to perform manual operations beside the container where a large amount of heat and smoke are released during a fire, there is a problem that the operator is exposed to the risks of fire and explosion.

[0005] In addition, when a fire occurs in a container at a high position due to multi-layer stacking, it is necessary to install a ladder according to the height of the corresponding container and then have the operator directly climb up the ladder to drill holes in the container door, which also causes problems of being exposed to many risks.

[0006] In particular, even if an operator personally uses a hammer to complete drilling, when a large amount of hot air jets out through the drilled hole, it is very difficult and dangerous for the operator to personally insert a water spray gun. Therefore, a technology is needed that does not require the operator to personally perform the above-mentioned fire extinguishing operation but can safely extinguish the fire. Summary of the Invention

[0007] The present invention aims to solve the above-mentioned problems and provides a hydraulic drilling spray gun for extinguishing fires in containers. When a fire occurs in a container, it can drill holes in the container door by using water pressure to form fire extinguishing holes and then spray water to extinguish the fire. Moreover, it can quickly extinguish the fire without being restricted by the height of stacked containers through vertical height adjustment.

[0008] The hydraulic drilling spray gun for extinguishing fires in containers according to an embodiment of the present invention may include: a clamp body 110 that is attached to the container door; a lock hook assembly 120 that is provided on the clamp body 110 and can be fixed or unfixed to a locking rod of the container by rotation; a drill bit module 130 that is provided on the clamp body 110 and drills the container door with water injected from the outside and sprays water into the container through the drilled hole; and a lance support 140 that is connected to the clamp body 110 and is used to connect to an externally adjustable-height lifting rod.

[0009] In one embodiment, in the clamp body 110, a receiving groove 111 for receiving the locking rod in the longitudinal direction may be formed.

[0010] In one embodiment, the lock hook assembly 120 may include: a rotation guide 121 that is provided on the inner side of the clamp body 110; a lock hook 122 that is connected to the rotation guide 121 by a shaft and can be rotationally engaged or disengaged with the locking rod; a shaft rod 123 that is connected to the lock hook 122 and is used to pull or push the lock hook 122; and a trigger 124, one end of which is connected to the shaft rod 123 and the center of which is connected to the clamp body 110 by a shaft, and pulls or pushes the shaft rod 123 according to the direction of rotation of the end; when the trigger 124 rotates from the upper side to the lower side, the shaft rod 123 will push the lock hook 122, and the lock hook 122 will rotate around the rotation guide 121 and be engaged with the locking rod.

[0011] In one embodiment, a wire for pulling the trigger 124 downward may be connected to the end of the trigger 124.

[0012] In one embodiment, on one side of the spray gun bracket 140, a clamping component 141 may protrude in a manner that it is located below the trigger 124. When the spray gun bracket 140 is connected to the clamp body 110 and rotates by a certain angle from the clamp body 110, when the spray gun bracket 140 rotates, the clamping component 141 pushes the end part of the trigger 124 from the lower side to the upper side, and thereby the shaft rod 123 pulls the locking hook 122. The locking hook 122 is disengaged from the locking rod by rotating around the rotation guide 121.

[0013] In one embodiment, the drill bit module 130 may include: a housing 131 into which water can be injected; an impeller 132 disposed inside the housing 131, which rotates by the injected water and generates a rotational force; a center drill bit 133 connected to the impeller 132, which drills a center hole in the container door by the rotational force of the impeller 132 in a state of being in contact with the container door; a hole opener 134 connected to the impeller 132, which drills a fire extinguishing hole for injecting water into the container interior by the rotational force of the impeller 132; a bearing cover 135 covering the bearing disposed between the housing 131 and the impeller 132; and a drill bit guide shaft 136 connected to the center drill bit 133.

[0014] In one embodiment, on the outside of the clamp body 110, a pair of sliding guides 112 may protrude toward the housing 131. On the outside of the housing 131, a pair of sliding wings 131a are formed to engage with the pair of sliding guides 112. In a state where the pair of sliding wings 131a are engaged with the pair of sliding guides 112, the drill bit module 130 slides along the pair of sliding guides 112 in a manner of moving away from or approaching the clamp body 110.

[0015] In one embodiment, at the end parts of the pair of sliding guides 112, a guide channel 112a may be provided to prevent the housing 131 from separating from the pair of sliding guides 112.

[0016] In one embodiment, an elastomer may be provided between the guide channel 112a and the pair of sliding wings 131a, and by the elastic force of the elastomer, the housing 131 maintains a state of being in contact with the clamp body 110.

[0017] In one embodiment, when the clamp body 110 is pressed against the container door, the center drill bit 133 can cause the housing 131 to be separated from the clamp body 110 by contacting the container door. During the process of drilling the container door with the center drill bit 133 and the hole opener 134, the distance between the housing 131 and the clamp body 110 gradually narrows and presses close by virtue of the elastic force of the elastomer.

[0018] In one embodiment, on the lower side of the housing 131, a drain hole 131b can be provided for discharging the water injected into the interior to the outside when the impeller 132 rotates.

[0019] In one embodiment, on the outer side of the clamp body 110, a drain plate 113 can be provided which, during the process of drilling the container door with the center drill bit 133 and the hole opener 134, when the distance between the housing 131 and the clamp body 110 gradually narrows and presses close by virtue of the elastic force of the elastomer, blocks the drain hole 131b so that the water injected into the housing 131 does not drain through the drain hole 131b, but induces it to be injected into the container interior through the fire extinguishing hole.

[0020] According to the present invention, it is not necessary for an operator to drill holes in the container door manually with a hammer. Instead, after automatically drilling fire extinguishing holes in the container door using water pressure, the fire can be extinguished by spraying water.

[0021] Furthermore, according to the present invention, the fire can be extinguished quickly without being restricted by the height of the multi - stacked containers through vertical height adjustment.

[0022] In particular, according to the present invention, it is not necessary for an operator to perform operations such as drilling holes in the container door and spraying water to extinguish the fire, and the fire can be extinguished safely. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those with general knowledge in the technical field to which the present invention belongs can easily implement the present invention. The present invention can be implemented in various different forms and is not limited to the embodiments described herein.

[0064] In order to clearly describe the present invention, parts irrelevant to the description will be omitted, and throughout the specification, the same reference numerals will be assigned to the same or similar components.

[0065] In addition, in multiple embodiments, the same reference numerals will be used for components with the same composition and only described in the representative embodiments, and in other embodiments, only the components different from the representative embodiments will be described.

[0066] Throughout the specification, when it is described that a certain part is "connected" to another part, it includes not only the case of "direct connection" but also the case of "indirect connection" with other components intervening therebetween. In addition, when it is described that a certain part "includes" a certain component, unless there is a clear contrary description, it does not mean excluding other components, but means that other components can also be included.

[0067] Figure 1It is a schematic diagram showing the structure of the hydraulic drilling spray gun 100 for container fire extinguishing according to an embodiment of the present invention.

[0068] Refer to Figure 1 , the hydraulic drilling spray gun 100 for container fire extinguishing according to an embodiment of the present invention generally includes: a clamp body 110, which is attached to the container door; a locking hook assembly 120, which is arranged on the clamp body 110 and fixed to a locking rod; a drill bit module 130, which drills the container door and sprays water into the interior; and a lance support 140, which is arranged on the clamp body 110 and is connected to an external lifting rod with adjustable height.

[0069] First of all, the clamp body 110 is tightly attached to the container door and serves as a support for stably installing the drill bit module 130 described later to the container door.

[0070] Figure 2 It is a schematic diagram specifically showing the clamp body 110.

[0071] Refer to Figure 2 , a plurality of receiving grooves 111 for receiving the locking rods of the container in the length direction are respectively formed on the upper side and the lower side of the clamp body 110. The receiving grooves 111 are formed according to the number and position of the locking rods of the container, and are formed in a shape corresponding to the surrounding shape of the locking rod so that the locking rods are perfectly attached without gaps.

[0072] An open area is formed in the central part of the clamp body 110 for the central drill bit 133 and the hole opener 134 of the drill bit module 130 described later to enter inward. By attaching the clamp body 110 to the container door, the container door can be stably drilled by the central drill bit 133 and the hole opener 134.

[0073] In addition, a locking hook assembly 120 for firmly fixing the clamp body 110 attached to the container door to prevent it from separating is arranged inside the clamp body 110.

[0074] The locking hook assembly 120 is arranged inside the clamp body 110 and serves to be combined with the locking rod by rotation to firmly fix the clamp body 110 to prevent it from moving, or to separate the clamp body 110 from the locking rod by releasing the combination.

[0075] The locking hook assembly 120 as described above is composed of a rotation guide 121, a locking hook 122, a shaft rod 123 and a trigger 124.

[0076] The rotation guide 121 is located in the open area formed on the clamp body 110 and can act as an axis for the locking hook 122 to rotate about the rotation guide 121.

[0077] The locking hook 122 is formed in the shape of a hook and can be snap - coupled to the locking rod by rotating in one direction or separated from the locking rod by rotating in the opposite direction. When one side of the locking hook 122 is pushed by the shaft rod 123, it will rotate about the rotation guide 121 in the direction approaching the locking rod. On the contrary, when the shaft rod 123 is pulled, the locking hook 122 will rotate in the opposite direction about the rotation guide 121 in the direction away from the locking rod.

[0078] One side of the shaft rod 123 is connected to the locking hook 122, and the other side is connected to the trigger 124. The shaft rod 123 can linearly move in the direction of pushing the locking hook 122 or in the direction of pulling the locking hook 122 according to the rotation direction of the trigger 124.

[0079] The trigger 124 is a kind of switch for rotating the locking hook 122 and one end is connected to the shaft rod 123. When the end part of the trigger 124 is located on the upper side, it is equivalent to the state where the shaft rod 123 is pulled, which is also equivalent to the state where the locking hook 122 rotates in the direction away from the locking rod. This is further equivalent to the situation where the clamp body 110 is installed on the container door.

[0080] On the contrary, when the end part of the trigger 124 is pulled to the lower side, it is equivalent to the state where the shaft rod 123 is pushed, which is also equivalent to the state where the locking hook 122 rotates about the rotation guide rod 121 in the direction approaching the locking rod. Thereby, by making the locking hook 122 snap - coupled to the locking rod, the clamp body 110 can be firmly fixed to the container door. At this time, a wire for an operator to pull the trigger 124 downward can be connected to the end part of the trigger 124.

[0081] Next, the above - mentioned process will be described.

[0082] Figure 3 It is a schematic diagram showing the process of fixing or releasing the fixation between the locking hook assembly 120 and the locking rod.

[0083] Refer to Figure 3 , in the state where the clamp body 110 is not installed on the container door, the trigger 124 is in the upward - facing position, and since the shaft rod 123 pulls the locking hook 122, the locking rod will be engaged with the receiving groove 111. In the above - mentioned state, when the operator pulls the wire, the trigger 124 will move downward. At this time, the shaft rod 123 will push the locking hook 122, causing the locking hook 122 to rotate and engage with the locking rod.

[0084] In the case where the trigger 124 needs to be lifted back to the upper side, the engaging component 141 located below the trigger 124 will touch the trigger 124 upward to lift it. The engaging component 141 will be specifically introduced in the spray gun bracket 140 which will be described later.

[0085] The drill bit module 130 is provided on the outside of the clamp body 110 in the direction facing the container door, and can function to drill the container door with water injected from the outside, and to extinguish the fire inside the container by spraying water during drilling. Next, it will be described.

[0086] Figure 4 is a schematic diagram specifically showing the drill bit module 130, and Figure 5 is a schematic diagram showing the process of drilling the container door by the drill bit module 130.

[0087] Refer to Figure 4 and Figure 5 , the drill bit module 130 generally may include a housing 131, an impeller 132, a center drill bit 133, a hole opener 134, a bearing cover 135, and a drill bit guide shaft 136.

[0088] The housing 131 is provided on the outside of the clamp body 110, and houses the impeller 132, the center drill bit 133, and the hole opener 134 inside. In addition, a water injection port for injecting water into the interior is provided on one side of the housing 131, and the impeller 132 inside rotates by the water pressure of the water injected through the water injection port. The rotational force of the impeller 132 is directly transmitted to the center drill bit 133 and the hole opener 134. As a result, the center drill bit 133 and the hole opener 134 can drill the container door by the water pressure.

[0089] The water injected through the water injection port provided on the housing 131 will rotate along the inner wall of the housing 131, thereby driving the impeller 132 to rotate.

[0090] The impeller 132 will generate a rotational force by the water pressure and drive the center drill bit 133 and the hole opener 134 to rotate by the rotational force.

[0091] The center drill bit 133 is in a protruding shape that can first adhere to the container door, and drills a center hole in the container door while rotating by the rotational force of the impeller 132.

[0092] In the case where a center hole of a certain depth is drilled by the center drill bit 133, the hole opener 134 will continue to rotate by the rotational force of the impeller 132 and drill a fire extinguishing hole in the container door. Since the diameter of the fire extinguishing hole is larger than that of the center hole, a large amount of water can be injected into the container through the fire extinguishing hole and the fire can be extinguished more effectively thereby.

[0093] In addition, before drilling is completed on the container door by means of the center drill bit 133 and the hole opener 134, the water injected through the water injection port needs to be discharged to the outside, and for this purpose, a drain hole 131b can be formed on the lower side of the outer shell 131.

[0094] In addition, the outer shell 131 will gradually approach the clamp body 110 from the outside of the clamp body 110 based on the elastic force of the elastomer, so that the center drill bit 133 and the hole opener 134 can continuously drill the container door, and the following will be described.

[0095] On the outside of the clamp body 110, a pair of sliding guides 112 are formed to protrude toward the outer shell 131. On the outside of the outer shell 131, a pair of sliding wings 131a are formed for engaging with the pair of sliding guides 112 as described above.

[0096] The outer shell 131 moves away from or approaches the clamp body 110 by linearly moving along the sliding guides 112. In particular, at the end portions of the pair of sliding guides 112, a guide channel 112a is provided to prevent the outer shell 131 from separating from the sliding guides 112. Thus, even when the outer shell 113 moves away from the clamp body 110, it will be blocked by the guide channel 112a and will not separate outward.

[0097] In addition, an elastomer with an elastic force is provided between the guide channel 112a and the pair of sliding wings 131a. The elastomer uses the elastic force to push the pair of sliding wings 131a, so that the outer shell 131 always maintains a state of being tightly attached to the clamp body 110.

[0098] When the clamp body 110 is installed on the container door, the outer shell 131 will linearly move along the sliding guides 112 and move away from the clamp body 110 by means of the relatively more protruding center drill bit 133. This is because the elastomer is in a compressed state, that is, a state in which an elastic force is formed in the elastomer.

[0099] In the state as described above, the impeller 132 will rotate by means of the water pressure and drive the center drill bit 133 and the hole opener 134 to rotate together, so as to gradually drill the container door, and the center drill bit 133 and the hole opener 134 will drill into the container door. This is because the elastomer can always push the outer shell 131 toward the clamp body 110 through the elastic force.

[0100] In addition, on the lower side of the outer shell 131, a drain hole 131b is formed to discharge the injected water to the outside before drilling is completed by means of the center drill bit 133 and the hole opener 134.

[0101] The drain hole 131b can function as a drain opening for discharging the injected water to the outside before drilling is completed by means of the center drill 133 and the hole opener 134. At this time, after drilling is completed by means of the center drill 133 and the hole opener 134, in order to prevent the water injected through the water injection port from being discharged to the outside through the drain hole 131b, a drain plate 113 for covering the drain hole 131b is formed on the clamp body 110.

[0102] The drain plate 113 is formed to protrude outward from the clamp body 110 in the direction toward the drain hole 131b, so it will not block the drain hole 131b when the housing 131 is away from the clamp body 110. However, during the process of drilling the container door by means of the center drill 133 and the hole opener 134, when the housing 131 gradually approaches and adheres to the clamp body 110 by the elastic force of the elastic body, the drain plate 113 will gradually block the drain hole 131b and thereby induce the water to be injected into the container interior through the fire extinguishing hole instead of being discharged through the drain hole 131b.

[0103] That is, when drilling the container door by means of the center drill 133 and the hole opener 134 and causing the housing 131 to gradually approach the clamp body 110, the drain plate 113 will naturally cover the drain hole 131b. Thereby, the water injected into the housing 131 can be naturally injected into the container interior through the fire extinguishing hole.

[0104] The spray gun holder 140 is connected to one side of the clamp body 110 and connected to an externally adjustable-height lifting rod, so it can be used when it is necessary to install the clamp body 110 on the container door at a relatively high position.

[0105] Specifically, the spray gun holder 140 is not a connection structure that is completely fixed to the clamp body 110 and cannot move, but is connected by a connection part that can rotate at a certain angle in part. Thus, when the operator pulls the lifting rod downward, it rotates downward at a certain angle with the connection part to the clamp body 110 as the axis.

[0106] In the spray gun holder 140, a clamping component 141 can be formed to protrude toward the lower side of the trigger 124 as described above. At this time, after extinguishing the fire, the lifting handle of the lifting rod device can be rotated in the opposite direction to lower a part of the lifting rod and thereby release the fixed state of the gear. When a part of the lifting rod is lifted upward by rotating the lifting handle in the above state, the clamping component 141 of the spray gun holder 140 will lift the trigger 124 and release the locking state of the locking hook 122, so that the clamp body 110 can be easily separated from the container. The lifting rod connected to the spray gun holder 140 can be used when it is necessary to install the clamp body 110 on the container door at the upper layer of multiple stacked containers.

[0107] Next, the lifting rod connected to the spray gun bracket 140 will be described.

[0108] Figure 6 It is a schematic diagram showing the structure of the lifting rod device 200 for adjusting the height of the hydraulic drilling spray gun. Figure 7 It is a schematic diagram specifically showing the lifting rod 210 and the locking rod 211, while Figure 8 It is a schematic diagram showing the state where the locking rod 211 is fixed to the railing.

[0109] Refer to Figures 6 to 8 , the lifting rod device 200 for adjusting the height of the hydraulic drilling spray gun can generally include a multi-section lifting rod 210 connected to the spray gun bracket of the hydraulic drilling spray gun, a gear assembly 220, and a lifting handle 230.

[0110] First of all, the lifting rod 210 can be formed in multiple sections in a telescopic manner and can adjust the height thereby. Therefore, even in the case of multi-layer stacked containers, the hydraulic drilling spray gun 100 for container fire extinguishing can be installed without height restrictions.

[0111] As the above-mentioned lifting rod 210 of each section, square tubes with different pipe diameters can be applied, and it is in a form where the diameter gradually decreases upward from the lowermost lifting rod 210.

[0112] In particular, the spray gun bracket 140 is connected to the uppermost lifting rod 210, and the locking rod 211 for fixing to the railing installed on the front of the container door is provided on the lowermost lifting rod 210.

[0113] The locking rod 211 is fixed to the lowermost lifting rod 210 through a fixed bracket 211a. In particular, it is formed in such a way that the height can be adjusted along the lowermost lifting rod 210 when the fixed state of the fixed bracket 211a is released.

[0114] Refer to Figure 8 , the locking rod 211 can be firmly fixed to the railing by rotating downward through the clamping assembly in the state of being placed on the cross-bar-shaped railing installed on the front of the container door. In particular, the clamping assembly can always maintain the state of rotating downward by its own weight. Therefore, unless the operator rotates the clamping assembly upward personally, the locking rod 211 can maintain the state of being firmly fixed to the railing. Through the fixation of the locking rod 211 as described above, the lifting rod 210 can maintain a vertical state without tipping over.

[0115] In addition, a gear assembly 220 is provided on the upper side of each section of the lifting rod 210.

[0116] The gear assembly 220 is provided on the upper side of each section of the lifting rod 210 and can mesh with the gear groove 210a formed on the side of another lifting rod 210 (referring to the lifting rod with a smaller diameter) introduced into the inside through gears.

[0117] At this time, a rotation fixing component that fixes its rotation state after rotating only in one direction can be provided on the gear. Therefore, the lifting rod 210 introduced into the inside can maintain the state of being led out upward by means of the gear.

[0118] At this time, a lifting handle 230 for rotating the inner gear is provided on one side of the gear assembly 220.

[0119] Figure 9 It is a schematic diagram showing the process of adjusting the height of the lifting rod 210 using the lifting handle 230.

[0120] Refer to Figure 9 , because the lifting handle 230 is basically formed in a separable manner from the gear assembly 220, the lifting handle 230 is not provided for each gear assembly 220. Instead, after leading out the uppermost lifting rod 210, the corresponding lifting handle 230 can be separated from the corresponding gear assembly 220, and then combined with the gear assembly 220 located on another lifting rod 210 (referring to the lifting rod with a diameter one size larger), and then the process of leading out the lifting rod 210 is repeated.

[0121] On the contrary, in the case where it is necessary to introduce each section of the lifting rod 210, the lifting handle 230 can be rotated in the opposite direction with the lifting handle 230 combined with the lowermost lifting rod 210, so as to introduce the lifting rod 210 inside the lowermost lifting rod 210. By repeating the above process, all the lifting rods 210 can be restored to the original state again.

[0122] Next, the overall process of extinguishing a container fire using a hydraulic drilling spray gun for container fire extinguishing will be described in sequence.

[0123] Figure 10 It is a schematic diagram showing the overall process of extinguishing a container fire using a hydraulic drilling spray gun for container fire extinguishing in sequence.

[0124] Refer to Figure 10 , first, after arranging the lifting rod 210 on the railing installed on the front of the container door, the locking rod 211 is fixed to the corresponding railing.

[0125] In the state described above, after connecting the lifting handle 230 to the gear assembly 220 equipped on the lowermost lifting rod 210 and rotating it, the inner lifting rod 210 meshing with the gear inside the gear assembly 220 is drawn out, thereby increasing its height by a section. By repeating the process described above, the fire-fighting hydraulic drilling spray gun connected to the uppermost lifting rod 210 can be moved to the height of the container door where the fire occurs.

[0126] In the state where the fire-fighting hydraulic drilling spray gun 100 for containers is arranged in front of the container door where the fire occurs, the clamp body 110 is pressed against the container door. In the state described above, by pulling the wire connected to the trigger 124 of the hook assembly 120, the hook 122 can be engaged with the locking rod, and thereby the clamp body 110 can be firmly fixed.

[0127] In the state described above, when water is supplied through the water injection port of the housing 131, the impeller 132 will rotate, and the center drill bit 133 connected to the impeller 132 will also rotate and drill a center hole in the container door. At this time, the center drill bit 133 can be pressed against the container door by the elastic force of the elastic body. After drilling the center hole, the hole opener 134 will be pressed against the container door and continue to drill to form a fire-extinguishing hole.

[0128] When the drilling of the fire-extinguishing hole is completed, the drain plate 113 will block the drain hole 131b, so that the water injected into the water injection port will be injected and sprayed into the container through the fire-extinguishing hole instead of the drain hole 131b to extinguish the fire inside the container.

[0129] After the fire is extinguished, by rotating the lifting handle 230, the lifting rod 210 is lifted upward by 2 to 3 grids. By this means, the clamping component 141 equipped on the spray gun bracket 140 can push the trigger 124 upward and disengage the hook 122 from the locking rod, so that the clamp body 110 can be easily separated from the container door.

[0130] After separating the clamp body 110, the lifting handle 230 is connected to the gear assembly 220 equipped on the lowermost lifting rod 210 and rotated, thereby introducing the inner lifting rod 210 meshing with the gear inside the gear assembly 220 and reducing its height by a section. By repeating the process described above, the installation of the fire-fighting hydraulic drilling spray gun 100 for containers is removed.

[0131] In the above content, the preferred embodiments of the present invention are described for reference. However, those skilled in the relevant technical field should understand that the present invention can be modified and changed in various ways without departing from the idea and gist of the present invention recorded in the appended claims.
