Description

Electric vehicle fire suppression tank with retractable walls

[0001] The present invention relates to an electric vehicle fire suppression tank equipped with a retractable wall, which, when a fire occurs in an electric vehicle, surrounds the electric vehicle using a main wall and a retractable wall, forms a water tank, and fills the tank with fire water to quickly extinguish the fire.

[0002] In the case of a fire in an electric vehicle, thermal runaway of the lithium-ion battery occurs, and in this case, the fire spreads from the thermal runaway cell to the adjacent battery cell, so in order to extinguish the fire, the entire battery section must be submerged in a large amount of water.

[0003] In this regard, the Ilsan Fire Department conducted an electric vehicle fire suppression experiment using a portable water tank in April 2021. The electric vehicle on fire was extinguished by submerging it in the tank. However, the actual installation, filling, and moving of the tank took approximately 40 minutes, raising concerns about the need for additional time.

[0004] Currently, the most effective method for extinguishing an electric vehicle fire is to cool it with a large amount of water. However, as seen in the thermal runaway mechanism, heat is needed for the next stage of continuous reaction runaway to occur, and if controlled through cooling, the chain reaction runaway can be stopped.

[0005] Therefore, the present invention aims to quickly install a fire barrier and, in particular, to simultaneously confine a large amount of fire extinguishing water to the fire barrier so that the battery compartment of an electric vehicle can be completely submerged.

[0006] The present invention has been devised to solve the above-mentioned problems,

[0007] In the event of an electric vehicle fire, the purpose is to surround the electric vehicle using the main wall and the retractable wall, form a water tank, and fill the tank with firefighters to quickly extinguish the fire.

[0008] The present invention has a lower support structure of a tube structure composed of two stages, a support tube filled with water, and a wall-forming tube placed on top of the support tube and filled with air, so that not only can the deployment of the main wall and the retractable wall be realized by only filling the support tube and the wall-forming tube with water and air, but also another object is to ensure that even if one tube is damaged by configuring the support tube in two stages, there is no problem in forming the wall.

[0009] Another object of the present invention is to improve economic efficiency by not only allowing the support tube of the tube structure to be filled with water and come into close contact with the ground, but also preventing the water filling the tank from escaping to the outside, thereby eliminating the need for a separate watertight structure.

[0010] An electric vehicle fire suppression tank equipped with a retractable wall according to the present invention comprises: a main wall formed by interconnecting a plurality of walls and having an opening formed on one side; a retractable wall configured to open and close the opening of the main wall; a coupling means for enabling coupling and separation between the opening end of the main wall and the retractable wall; a tube structure configured to form each wall of the main wall and the retractable wall in a plurality of stages and filled with different fluids; and a hose inlet provided in the main wall, the retractable wall, or both, for enabling water injection and drainage.

[0011] The coupling means according to the present invention is characterized by including a waterproof zipper formed at the opening end of the main wall and at both ends of the openable wall.

[0012] The waterproof zipper of the above-described coupling means according to the present invention is characterized in that a safety handle is further provided on the zipper slider to ensure convenience in coupling and disassembling operations.

[0013] The tube structure according to the present invention is characterized in that it comprises at least one tube to form a lower support structure, a support tube filled with water, and a wall forming tube arranged on the upper portion of the support tube to form an upper wall structure and filled with air.

[0014] According to the present invention, a hose is connected to the hose inlet, and the hose inlet is characterized in that it is provided on each surface when a multi-faceted structure is formed by the main wall and the openable wall.

[0015] Each of the above walls according to the present invention is further characterized by having a detachable portion for mounting a hose connected to the hose inlet.

[0016] The upper height of the hose mounted on the detachable portion according to the present invention is characterized in that it is formed higher than the surface height of the water filled in the tank.

[0017] The main wall according to the present invention is characterized in that a plurality of first walls are connected to both ends of the first wall to form a 'ㄷ' shaped wall when deployed, and the connecting means are formed at each end of the second wall and both ends of the openable wall.

[0018] The length of the first wall according to the present invention is longer than the length of the second wall and is characterized by being the same as that of the openable wall.

[0019] The main wall according to the present invention is characterized in that the first and second walls are formed in a right-angled shape when deployed by connecting the respective ends of the first and second walls, the retractable wall is characterized in that the third and fourth walls are formed in a right-angled shape when deployed by connecting the respective ends of the third and fourth walls, and the connecting means is formed in the respective ends of the first and second walls of the main wall and the respective ends of the third and fourth walls of the retractable wall.

[0020] According to the present invention, the lengths of the first and third walls are longer than the lengths of the second and fourth walls, and the length between the first and third walls and the length between the second and fourth walls are equal to each other.

[0021] The electric vehicle fire suppression tank equipped with a retractable wall according to the present invention can, when a fire occurs in an electric vehicle, surround the electric vehicle using the main wall and the retractable wall, form a tank, and then fill the tank with firefighting water to quickly extinguish the fire.

[0022] In addition, the present invention comprises a two-stage lower support structure of a tube structure, which comprises a support tube filled with water and a wall-forming tube placed on the upper part of the support tube and filled with air, so that the deployment of the main wall and the openable wall can be realized by simply filling the support tube and the wall-forming tube with water and air.

[0023] In addition, the reliability of the device can be ensured in that the present invention comprises two support tubes, so that even if one tube is damaged, there is no problem in forming the wall.

[0024] In addition, the present invention can prevent the water filling the tank from leaking out by not only making the support tube of the tube structure close to the ground while being filled with water, but also by doing so.

[0025] In addition, the present invention can improve economic efficiency in that it is possible to avoid employing a separate watertight structure to prevent water leakage from the tank.

[0043] In order to explain the operational advantages of the present invention and the purpose achieved by the implementation of the present invention, preferred embodiments of the present invention are exemplified and examined with reference thereto below.

[0044] First, the terms used in this application are only used to describe specific embodiments and are not intended to limit the present invention, and the singular expression may include plural expressions unless the context clearly indicates otherwise. In addition, it should be understood that the terms "comprise" or "have" in this application are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, and do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0045] In describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

[0046]

[0047] As shown in FIGS. 1 to 3, the electric vehicle fire suppression tank equipped with a retractable wall (20) according to the present invention is configured to include a main wall (10), a retractable wall (20), a coupling means (30), a tube structure (40), and a hose inlet.

[0048]

[0049] First, as shown in FIGS. 1 to 3, the main wall (10) according to the present invention is formed by connecting a plurality of walls to each other and forming an opening on one side.

[0050] The main wall (10) may be formed of a first wall (11) and a second wall (13), and in this case, the length of the first wall (11) may be formed longer than the length of the second wall (13). This is because the fire suppression tank according to the present invention must form a tank surrounding the electric vehicle (C) with the main wall (10) and the later-described openable wall (20) to suppress a fire in the electric vehicle (C), and therefore, the length of the first wall (11) is formed longer than the length of the second wall (13).

[0051] In this case, when the main wall (10) is composed of one first wall (11) and two second walls (13) as shown in the drawing 1, when the main wall (10) is deployed, the long first wall (11) forms one side, and the second walls (13) are respectively connected to both ends of the first wall (11) to form the front and the back, thereby forming a structure having an approximate 'ㄷ' shape. In this case, the movable wall (20) is connected to each end of the second wall (13) by a connecting means (30) to form the other side. At this time, each end of the second wall (13) of the main wall (10) may be spaced apart, and an opening may be formed in the spaced apart space.

[0052] Here, the front, rear, and one side where the main wall (10) is formed are set based on the side wall surface adjacent to the electric vehicle (C) placed inside the tank.

[0053] Accordingly, the first wall (11) and the movable wall (20) can be arranged to face the side of the electric vehicle (C), and each second wall (13) can be arranged to face the front and water surface of the electric vehicle (C), respectively.

[0054] Meanwhile, when the main wall (10) is formed as shown in the drawing of Fig. 2, the first wall (11) and the second wall (13) are each arranged singly and connected to each other, and when deployed, the first wall (11) and the second wall (13) can form a structure in a roughly 'ㄱ' shape at right angles. Accordingly, the first wall (11) can form one side, and the second wall (13) can form the front or the back. In this case, the movable wall (20) is connected to the end of the second wall (13) by the connecting means (30) through the third wall (21), and the fourth wall (23) is connected to the end of the first wall (11), so that the third wall (21) forms the other side, and the fourth wall (23) can form the back or the front. At this time, an opening can be formed in the space between the ends spaced apart from each other in the first and second walls (13) of the main wall (10).

[0055] In this case, the lengths of the first wall (11) and the third wall (21) are the same, the lengths of the second wall (13) and the fourth wall (23) are the same, and the lengths of the first and third walls (11)(21) are formed to be longer than the lengths of the second and fourth walls (13)(23), so that the first and third walls (11)(21) can be arranged to face the side of the electric vehicle (C) placed inside the tank, and the second and fourth walls (13)(23) can be arranged to face the front and rear of the electric vehicle (C).

[0056]

[0057] As shown in FIGS. 1 to 4, the openable wall (20) according to the present invention is configured to be able to close the opening of the main wall (10) by means of a connecting means (30) to be described later.

[0058] The opening / closing wall (20) can be formed as a single wall having the same length as the first wall (11) when the main wall (10) is formed in a 'ㄷ' shape by the first and second walls (13) as shown in Fig. 1. In this case, the opening / closing wall can be connected at both ends to the opening ends of the main wall (10), i.e., to each end of the second wall (13), by means of a connecting means (30) to form a square-shaped water tank.

[0059] When the main wall (10) is formed in an 'ㄱ' shape by the first and second walls (11) (13) as shown in the illustration of Fig. 2, the movable wall (20) may be composed of a third wall (21) connected to the end of the second wall (13) of the main wall (10) and a fourth wall (23) connected to the end of the first wall (11) of the main wall (10). Accordingly, the movable wall (20) may be formed in an 'ㄴ' shape corresponding to the 'ㄱ' shaped main wall (10).

[0060] In this case, the opening / closing wall (20) can form a square-shaped water tank by connecting the opening end of the main wall (10), the end of the first wall (11) of the main wall (10), the end of the fourth wall (23) to the end of the second wall (13) of the main wall (10) by means of a connecting means (30).

[0061]

[0062] As shown in FIGS. 1 to 4, the coupling means (30) according to the present invention is configured to enable coupling and separation between the opening end of the main wall (10) and the openable wall (20).

[0063] Such a connecting means (30) may be composed of waterproof zippers (31) arranged at the opening end of the main wall (10) and both ends of the openable wall (20). That is, the connecting means (30) needs to prevent water leakage at each connecting point when connecting the main wall (10) and the openable wall (20). That is, if water leakage occurs in the water tank, the amount of firefighting water injected into the water tank may decrease, which may cause a problem in that smooth fire suppression becomes difficult.

[0064] Therefore, it is desirable to introduce a waterproof zipper (31) that can prevent water leakage at each connecting point of the main wall check and the openable wall (20) as a connecting means (30).

[0065] For this purpose, it is preferable to use a waterproof fastener as the connecting means (30), even when applying a fastener such as a Velcro in addition to a waterproof zipper (31).

[0066] In addition, it is preferable to connect a safety handle (33) to the zipper slider (31a) of the waterproof zipper (31) of the connecting means (30) to make connecting and separating operations more convenient. This can improve workability by allowing the worker to perform the operation more easily and conveniently by holding the safety handle (33) when connecting and separating the main wall (10) and the openable wall (20) using the connecting means (30).

[0067] In this way, when a fire occurs, the connecting means (30) can quickly form a water tank by simply having the worker hold the safety handle (33) and close the waterproof zipper (31) connected to the main wall (10) and the movable wall (20) while connecting the waterproof zipper (31), thereby meeting the speed of fire suppression.

[0068]

[0069] As illustrated in FIGS. 1 to 4, the tube structure (40) according to the present invention is configured to have multiple stages of each wall of the main wall (10) and an openable wall (20), and is configured so that different fluids can be filled to form the wall structure.

[0070] The tube structure (40) may be configured to include at least one tube to form a lower support structure, a support tube (41) filled with water, and a wall forming tube (43) placed on top of the support tube (41) to form an upper wall structure and filled with air.

[0071] The support tube (41) of the tube structure (40) has a first tube (41a) arranged at the top and a second tube (41b) arranged at the bottom of the first tube (41a), and water can be filled into each tube. That is, the support tube (41) fills the first and second tubes (41b) with water, thereby increasing the adhesion to the ground by the weight of the water filled in each tube, and thereby preventing the water contained inside the water tank from escaping.

[0072] In addition, forming the support tube (41) with the first tube (41a) and the second tube (41b) makes it impossible to fill the tank with water or erect a wall structure that leaks if the support tube (41) is formed as a single tube. Therefore, it is preferable to form multiple support tubes (41) so that the tank wall structure can be erected even if a problem occurs in one tube.

[0073] In this case, as illustrated in Fig. 7, each tube (41a) (41b) is provided with an injection port (45) for introducing water, so that water can be injected into each tube. In another embodiment, when the injection port (45) is provided singly in the first tube (41a) or the second tube (41b), a connecting passage can be formed inside each tube so that the tubes are in communication with each other. Accordingly, when water is filled in one tube, water can be filled in another tube through the connecting passage.

[0074] Additionally, the wall-forming tube (43) of the tube structure (40) may be formed on the upper portion of the first tube (41a) of the support tube (41) disposed at the upper portion. In this case, the wall-forming tube (43) may be filled with air to form a wall structure of a certain height. For this purpose, an injection port for injecting a gas such as air may be formed in the wall-forming tube (43).

[0075]

[0076] As shown in FIGS. 1 to 4, the hose inlet (50) according to the present invention is formed in the main wall (10) or the openable wall (20), or both, to enable the injection and drainage of water.

[0077] That is, a tank surrounding an electric vehicle (C) in which a fire has occurred, i.e., an electric vehicle (C), is constructed by a main wall (10), a retractable wall (20), a connecting means (30), and a tube support. When the tank is constructed in this manner, firefighting water is supplied to the inside of the tank through a hose inlet (50), and when the fire is extinguished, the firefighting water can be drained through the hose inlet (50).

[0078] A hose inlet (50) like this can be formed at the bottom of each wall and a hose (51) can be connected. In this case, the hose inlet (50) can be arranged on each surface when a multi-faceted structure is formed by the main wall ((10) and the openable wall (20). That is, it is preferable that the hose inlet (50) be arranged on each wall in a square-shaped tank.

[0079] Once the tank is erected, the hose (51) is connected to the hose inlet (50) and the hose (51) is connected to a fire hydrant or a water source to inject fire water into the tank. In this case, it is preferable to leave the hose (51) in place instead of removing it after the water injection is complete. This is because, after the water injection, when the hose (51) is separated, the fire water is discharged from the hose inlet (50), so there is an inconvenience in that a separate part, such as a plug, must be inserted into the hose inlet (50) to block the discharge of the fire water.

[0080] Therefore, in the present invention, a detachable portion (53) is formed on the outer surface of each wall so that a hose (51) can be placed thereon, thereby eliminating the need for a separate plug. Furthermore, after pouring water, the hose (51) can be easily placed on the detachable portion (53), thereby enhancing the convenience of operation. Furthermore, when draining fire water, if the hose (51) is detached from the detachable portion (53), the fire water inside the tank can be naturally and quickly discharged through the hose inlet (50) and the hose (51).

[0081] In this case, it is desirable that the upper height of the hose (51) mounted on the detachable portion (60) be formed higher than the surface height of the water filled in the tank.

[0082] Since the height of the top of the lake (51) is formed higher than the surface height of the fire water contained inside the tank, the height of the fire water filled in the lake (51) becomes the same as the height of the fire water contained in the tank due to pressure equilibrium, so that the fire water can be prevented from flowing back through the hose (51).

[0083] The fire water can be prevented from flowing back through a hose whose top height is formed higher than the height of the fire water in the tank.

[0084] As described above, by connecting the hose inlet (50) and the hose (51) to the hose inlet (50), and by allowing the hose (51) to be mounted on the detachable portion (53) formed on the outside of the wall, the inconvenience in operation, such as having to prevent the discharge of fire water by inserting a separate stopper into the inlet after previously injecting water into the tank through the inlet, can be completely eliminated.

[0085] In addition, it is also possible to use a fire hose (51a) connected to a hose (51) fitted into a hose inlet (50) by a quick connector (55) as shown in FIG. 5, or to directly connect a fire hose (51a) to the hose inlet (50) by a quick connector (55). In this case, when a fire hose (51a) is directly used, the diameter of the hose inlet (50) to which the fire hose (51a) is connected is increased, so not only is the speed of the fire water injection faster, but also, when the fire suppression is finished, the fire water inside the water column can be quickly discharged simply by pulling out the fire hose (51a) from the hose inlet (50), which is advantageous.

[0086] However, when using a separate hose (51) as described above, it is preferable that the separate hose (51) also be a hose corresponding to the diameter of the fire hose (51a).

[0087] The method of filling the water tank with fire water according to the present invention can also be done by filling the water tank with fire water from the outside to the inside using a hose (51) or a fire hose (51a), as shown in FIG. 6.

[0088] Also, when extinguishing a fire in an electric vehicle (C) as shown in the city of Fig. 5, it is desirable to cover the tank with a protective cloth (60) to prevent dust or gas generated during a fire from spreading to the surroundings.

[0089]

[0090] Meanwhile, the city of FIG. 8 shows a state in which the main wall (10) or the retractable wall (20) is rolled up and stored in a storage bag (70) after the fire has been extinguished. That is, after using the main wall (10) or the retractable wall (20), the volume is minimized, the zipper (71) of the storage bag (70) is opened, the rolled main wall or the retractable wall is placed in the storage bag (70), and the zipper (71) is closed for storage. When the main wall (10) or the retractable wall (20) is rolled up and stored in the storage bag (70) in this manner, the volume is minimized, making storage easy, and convenience can also be ensured when moving and transporting.

[0091]

[0092] The tube structure according to the present invention may further include a support tube (80) to increase the supporting force when the tank is deployed.

[0093] The support tube (80) is formed on the support tube (41) and the wall forming tube (43) as shown in FIG. 9. More specifically, it may include a first support body (81) that is connected to the wall forming tube (43) and is formed to be inclined in an outward direction, and a second support body (83) that is connected to the end of the first support body (81) and is connected to the support tube (41) and is in contact with the ground.

[0094] In this case, the first support (81) can be connected to the upper part of the wall-forming tube (43). If the wall-forming tube (43) has a multi-layer structure as illustrated in FIG. 9, that is, if it is composed of the first, second, and third wall-forming tubes (43a), (43b), and (43c) from the upper part, the first support (81) can be connected to the first wall-forming tube (43a) located at the upper part. In addition, it is preferable that the first support (81) is formed so as to be horizontally arranged by a certain length from the connection point of the first wall-forming tube (43) and then bent downward to form a certain angle. This is because when water is injected into the tank, the tank receives pressure in the outward direction in proportion to the amount of water, so in order to increase the supporting force by the first support (81), it is preferable that the first support (81) is formed so as to be inclined downward in the outward direction.

[0095] The second support (83) of the support tube can be arranged in a vertical direction so as to be connected to the lower end of the first support (81) and to the support tube (41). In this case, the second support (83) can be in contact with the ground so that the pressure applied to the first support (81) can be supported through the ground, thereby increasing the bearing capacity of the support tube (80). In this case, when the support tube (41) is formed in multiple layers with the first and second tubes (41a) (41b) as illustrated in FIG. 3, it is preferable that the second support (83) be connected to the second tube (41b) arranged at the bottom.

[0096] Furthermore, a plurality of support tubes (80) according to the present invention may be provided on each wall (11) (13) of the main wall and the opening / closing wall (20). In this case, the support tube (80) may further be provided with a third support (85) that connects the connection between the first support (81) and the second support (83) provided on each wall and is arranged in a horizontal direction.

[0097] The third support member (85) of the support tube is horizontally arranged at the point where the first support member (81) and the second support member (83) are connected and bent, as illustrated in FIG. 9, so as to support the adjacent support tube (80). At the same time, the pressure applied to the first support member (81) and the second support member (83) is dispersed, thereby evenly distributing the support force by the support tube (80), thereby enabling the implementation of a stable support structure.

[0098] Furthermore, when the wall-forming tube according to the present invention has a multi-layer structure, that is, the first to third wall-forming tubes may each be provided with an air injection valve. Accordingly, an air injection device may be connected through the air injection valve to supply air into the tube. In this case, the first support of the support tube connected to the first wall-forming tube is in communication with the first wall-forming tube, so that air can be injected. In addition, the second support is connected so as to be in communication with the first support, and at the same time, the third support is also in communication with the first support, so that when air is injected into the first wall-forming tube, air can be simultaneously injected into the support tube.

[0099]

[0100] Meanwhile, the main wall (10) and the openable wall (20) according to the present invention are configured to be connected and separated by means of a connecting means (30). In this case, a reinforcing part may be further provided to reinforce the connecting portion by the connecting means (30).

[0101] These reinforcing members may be positioned on the inner or outer side of the connection between the main wall (10) and the movable wall (20), or on both the inner and outer sides. The reinforcing member illustrated in Fig. 10 represents an inner reinforcing member (90) positioned on the inner side, and the reinforcing member illustrated in Fig. 11 represents an outer reinforcing member (100) positioned on the outer side.

[0102] First, the inner reinforcement (90) illustrated in FIG. 10 can be placed on the inside of the connection between the main wall (10) and the movable wall (20) to reinforce the airtightness performance. That is, the inner reinforcement (90) is added to the connection between the main wall (10) and the movable wall (20) so that when the water tank is filled with water, it can be pressed against the connection between the main wall (10) and the movable wall (20) by the water pressure. Airtightness can be maintained by the adhesion between the inner reinforcement (90) and the inside of the connection between the main wall (10) and the movable wall (20).

[0103] In this case, an extension (91) extending inward may be provided at the bottom of the inner reinforcement (90), and a weight (93) having a predetermined weight may be placed on this extension (91). Such a weight (93) can prevent the inner extension (91) from floating on the water when the inside of the water tank is initially filled with water by supporting the extension (91) of the inner reinforcement (90) by applying pressure with a predetermined weight. Therefore, the weight (93) can prevent the inner reinforcement (90) from floating on the water, and at the same time, can improve the reliability of the product by allowing the inner reinforcement (90) to be stably attached to the connection between the main wall (10) and the openable wall (20).

[0104] In this case, it is also desirable to allow the upper part of the inner reinforcement (90) to extend outward beyond the tank, and to fix the portion extending outward to the outer surface of the tank so as to prevent the inner reinforcement (90) from flowing into the tank.

[0105] Next, the outer reinforcement member (100) illustrated in FIG. 11 may be arranged on the outside of the connection between the main wall (10) and the openable wall (20) to increase the bonding strength between the main wall (10) and the openable wall (20). That is, the outer reinforcement member (100) may be provided with a first detachable member (101) in the vertical direction at an adjacent end of the connection between the main wall (10) and the openable wall (20). In this case, the outer reinforcement member (100) may be provided with a first detachable member (101) and a detachable second detachable member (103) on both sides. Accordingly, by attaching the second detachable member (103) provided in the reinforcing member to the first detachable member (101) arranged around the connection between the main wall (10) and the openable wall (20), the bonding strength at the connection by the connection means (30) can be reinforced. In this case, the first and second detachable members (101) (103) can use a member such as Velcro, or a connecting member such as a hook and a hook that can be hung on the hook.

[0106] In this way, the connection between the main wall (10) and the openable wall (20) by the connecting means (30) is primarily reinforced by the external reinforcement (100), but it is also desirable to apply an additional reinforcement structure to further increase the reinforcement force.

[0107] That is, the additional reinforcing structure may be arranged in close proximity to the connection between the main wall (10) and the openable wall (20), and reinforcing rings (105) may be provided in corresponding positions. By connecting reinforcing ropes (107) to the reinforcing rings (105) arranged in corresponding positions and tightening them tightly, the reinforcing force can be increased. In this case, it is preferable to arrange a plurality of reinforcing rings (105) in the vertical direction and to tightly tighten multiple points vertically with reinforcing ropes (107) so that a stable reinforcing structure can be implemented.

[0108] In this case, the reinforcing ring (105) is preferably positioned adjacent to the first detachable member (101), but is preferably positioned in the outer direction so as not to interfere with the detachable movement by the outer reinforcing member (100).

[0109] Meanwhile, to reinforce the inner portion of the tank according to the present invention, a lower reinforcement member (98) may be further provided, connected to the support tube and positioned on the inner portion of the tank, as illustrated in FIG. 10. That is, when the tank is filled with water, the lower reinforcement member (98) can improve sealing performance by coming into close contact with the ground due to water pressure. Accordingly, water inside the tank can be prevented from leaking outward, thereby enhancing product reliability.

[0110]

[0111] Referring to FIGS. 12 to 15, a smart blower (100) according to one embodiment of the present invention may include a main body (100a), a power switch (102), a handle (103), a stand (104), an air inlet (105), an air outlet (106), and a pressure measuring terminal (116).

[0114] The power switch (102) is a power switch that supplies power to the smart blower (100), and may be provided with a button, an operation bar, a rotating unit, etc. that connects or disconnects the power switch at the bottom of the main body (100a).

[0115] A handle (103) may be provided on the upper portion of the main body (100a) so that a user can hold the smart blower (100). For example, the handle (103) may be formed in a loop shape including a grip portion that a user can hold with his or her hand and an insertion portion that is inserted into the space between the grip portion and the main body (100a). In this case, the handle (103) may be formed in various shapes, including a loop shape that allows a user to carry the smart blower while holding it.

[0116] A support (104) may be provided at the bottom of the smart blower (100). For example, the support (104) may be provided at both ends of the length of the main body (100a) to support the main body (100a) upright even in a poor space where water or mud accumulates on the floor. In this case, the support (104) may be formed in a box shape having a space therein.

[0117] Accordingly, the smart blower (100) is provided with a handle (103) on the upper part of the main body so that the user can easily carry it while holding the air pump, and the stand (104) provided on the lower part of the main body is designed to support the air pump while standing, so that it can be used even in poor spaces where water is accumulated on the floor or mud is accumulated, thereby maximizing the user's convenience.

[0118]

[0119] The air inlet (105) is provided on one side of the main body (100a) of the smart blower (100) and can inject air into the interior of the wall-forming tube (43) while being connected to the air hose. For example, the air inlet (105) can be connected by being inserted into an air hose connection part (124) provided on one end of an air hose (122), and when connected to the air hose connection part (124) of the air hose (122), the driving motor can be driven to inject air into the interior of the wall-forming tube (43) through the air inlet (105) and the air hose (122).

[0120] The air outlet (106) is provided on the other side of the main body (100 a) of the smart blower (100) and can discharge air from the inside of the wall-forming tube (43) while being connected to the air hose (122). At this time, the air outlet (106) has the same configuration as the air inlet (105), so a detailed description thereof is omitted.

[0121] Here, the air hose (122) may be connected to the smart blower (100) on one side and connected to the wall-forming tube (43) on the other side. For example, the air hose (122) may have air hose connecting portions (124) on both sides, may be connected to the air inlet (105) and the air outlet (106) of the smart blower on one side, and may be connected to the air injection valve (46) of the wall-forming tube (43) on the other side. This air hose (122) may induce air to be injected into the interior of the wall-forming tube (43) or discharged from the interior of the wall-forming tube (43) when connected to the smart blower (100) and the wall-forming tube (43).

[0122] The air hose connecting portion (124) can connect the air hose (122) and the main body (100a) of the smart blower (100). For example, the air hose connecting portion (124) is formed in a tubular shape including a hole for inserting the air inlet (105) of the smart blower (100) therein, and the air inlet (105) of the smart blower (100) can be inserted into the air hose connecting portion (124) and fixedly connected.

[0123] The pressure measuring terminal (116) can connect the pressure measuring line (114) and the main body (100a). For example, the pressure measuring terminal (116) is formed in a screw shaft shape that protrudes horizontally from one surface of the main body (100a), and can be fastened and fixed by being inserted into the open end of the pressure measuring line (114).

[0124] Here, the pressure measuring line (114) may have one end connected to the pressure measuring terminal (116) of the smart blower (100), and the other end connected to the pressure measuring hole (47) of the wall-forming tube (43). For example, the pressure measuring line (114) may be connected by having one end of an open shape inserted into the pressure measuring terminal (116). In addition, the pressure measuring line (114) may have the other end equipped with the pressure measuring sensor (112) connected to the pressure measuring hole (47) of the wall-forming tube (43), thereby detecting the internal pressure of the wall-forming tube (43).

[0125] Figure 16 is a block diagram of a smart blower according to one embodiment of the present invention.

[0126] Referring to FIG. 16, a smart blower (100) may include a pressure measurement sensor (112), a driving pump (120), a communication unit (130), an input unit (142), a display unit (144), and a control unit (150).

[0127] A pressure measuring sensor (112) can measure the pressure of a wall-forming tube (43). This pressure measuring sensor (112) is provided at one end of a pressure measuring line (114) and can be inserted into a pressure measuring hole (47) of the wall-forming tube (43).

[0128] The driving pump (120) can inject air into the wall-forming tube (43) or discharge air from the wall-forming tube (43). The driving pump (120) can be connected to the air injection valve (46) of the wall-forming tube (43) through an air hose (122). For example, the driving pump (120) can be connected to the air injection valve (46) of the wall-forming tube (43) by an air hose (122) having an air hose connection portion (124) to inject or discharge air into the wall-forming tube (43). At this time, the driving pump (120) is composed of a rotary motor and a rotary shaft, and can cause air to flow to the air inlet (105) and the air outlet (106) by rotating the impeller.

[0129] The communication unit (130) can perform external communication. For example, the communication unit (130) can perform short-range wireless communication such as Bluetooth or Wi-Fi. Optionally, the communication unit (130) can perform long-range wireless communication via a public wireless network. In this case, the communication unit (130) can communicate with the user's smartphone (160). That is, the smart blower (100) can operate the settings and control of operations by linking with the user's smartphone (160).

[0130] The input unit (142) and the display unit (144) are user interfaces of the smart blower (100), and are described in more detail with reference to FIG. 17.

[0131] The control unit (150) can be communicatively connected to the pressure measurement sensor (112), the driving pump (120), the communication unit (130), the input unit (142), and the display unit (144). The control unit (150) can control the overall operation of the smart blower (100). For example, the control unit (150) can control the operation of the driving pump (120) according to the settings of the input unit (142). Here, the operation settings can include the minimum pressure, maximum pressure, and exhaust pressure of the wall-forming tube (43). In this case, the exhaust pressure can be greater than the maximum pressure.

[0132] The control unit (150) can control the exhaust of the wall-forming tube (43) by driving the driving pump (120) when the pressure of the wall-forming tube (43) reaches the exhaust pressure. That is, the control unit (150) can control the exhaust of the wall-forming tube (43) so as to maintain a constant pressure without bursting due to internal expansion of the wall-forming tube (43).

[0133] In addition, the control unit (150) can control the transmission of the status of the wall-forming tube (43) to the user's smartphone (160). By this, the smartphone (160) can remotely control the operation of the driving pump (120).

[0134] FIG. 17 is a perspective view of an interface of a smart blower according to one embodiment of the present invention.

[0135] Referring to FIG. 17, the interface (140) may include an input unit (142) and a display unit (144).

[0136] The input unit (142) can input the driving settings of the drive pump (120) as described below. In addition, the input unit (142) has a function of allowing the user to input information selected from the information displayed on the display unit (144) and transmit the information to the control unit (150) to be described below. The input unit (142) can be configured as a general button type, but it is also possible to integrate the input unit with the display unit (144) by implementing it as a touch panel. For example, the input unit (142) can include a mode selection button (M), an increase button (+), a decrease button (-), and a decision button (OK). The mode selection button (M) can select a mode for setting. At this time, the mode can include a description of the minimum pressure, the maximum pressure, and the exhaust pressure. Here, the minimum pressure can be the minimum pressure at which the wall-forming tube (43) can maintain its shape. The maximum pressure can be the maximum set value of the air pressure to be injected into the wall-forming tube (43). The exhaust pressure is a set value that the wall forming tube (43) can maintain without bursting due to internal expansion.

[0137] The display unit (144) can display the pressure measured by the pressure measurement sensor (112) and the driving settings by the input unit (142). At this time, the display unit (144) can be configured as an LCD panel. The display unit (144) can display the mode selected on the left. For example, the display unit (144) can sequentially display the modes by individual LEDs. The display unit (144) can display pressure values ​​according to various settings or measurement values ​​in a numerical format in the central portion.

[0138] FIG. 18 is a drawing showing a state in which a smart blower according to one embodiment of the present invention is coupled to a wall-forming tube.

[0139] As shown in Fig. 18, the smart blower (100) is connected to one end of the air hose (122) and the air inlet (105) provided on one side of the main body (100a) of the smart blower (100) by means of air hose connecting parts (124) provided on both ends of the air hose (122), and the air hole (12) of the wall-forming tube (43) and one end of the air hose (122) are connected, and the driving pump is driven to inject air into the wall-forming tube (43). In addition, the smart blower (100) is connected to one end of the air hose (122) and the air outlet (106) provided on one side of the main body (100a) of the smart blower (100) by means of air hose connecting parts (124) provided on both ends of the air hose (122), and the air hole (12) of the wall-forming tube (43) and one end of the air hose (122) are connected, and the driving pump is driven to discharge air from the wall-forming tube (43).

[0140] In addition, the smart blower (100) is connected by having one side of the pressure measuring line (114) open and one end of the pressure measuring line (114) inserted into the pressure measuring terminal (116) provided on one side of the main body (100a) of the smart blower (100), and the other end of the pressure measuring line (114) provided with the pressure measuring sensor (112) is connected by being inserted into the pressure measuring hole (14) of the wall forming tube (43), so that the internal pressure of the wall forming tube (43) can be detected by the pressure measuring sensor (112).

[0141] The smart blower (100) can be connected to the user's smartphone (160). That is, the smart blower (100) can perform short-range wireless communication with the user's smartphone (160). Optionally, the smart blower (100) can perform long-range communication with the user's smartphone (160). In this case, the smart blower (100) can communicate with the user's smartphone (160) via a public network.

[0142] Hereinafter, the operation of a smart blower (100) according to one embodiment of the present invention will be described.

[0143]

[0144] First, one side of the air hose (122) is connected to the air injection valve (46) of the wall-forming tube (43), and the other side is connected to the air inlet (105) and the air outlet (106) of the main body (100a), thereby connecting the wall-forming tube (43) and the smart blower (100) via the air hose (122).

[0145] Next, one side of the pressure measuring line (114) is connected to the pressure measuring hole (47) of the wall forming tube (43), and the other side is connected to the pressure measuring terminal (116) of the main body (100a), thereby connecting the wall forming tube (43) and the smart blower (100) via the pressure measuring line (114).

[0146] Next, the driving settings of the driving pump (120), including the minimum pressure, maximum pressure, and exhaust pressure of the wall-forming tube (43), are input by the input unit (142). Here, the exhaust pressure may be greater than the maximum pressure.

[0147] Next, in a state where the smart blower (100) and the wall-forming tube (43) are connected by the air hose (122), the driving pump (120) is driven according to the driving setting of the driving pump (120) input to the input unit (142) to inject air into the interior of the wall-forming tube (43) through the air inlet (105) provided on one side of the main body (100a). At this time, the driving pump (120) can rotate forward to inject air into the interior of the wall-forming tube (43).

[0148] Next, the drive pump (120) is driven to inject air into the internal space of the wall-forming tube (43) to pressurize the wall-forming tube (43). At this time, while the smart blower (100) and the wall-forming tube (43) are connected by the pressure measuring line (114), the pressure measuring sensor (112) detects the internal pressure of the wall-forming tube (43) and transmits it to the control unit (150). Here, the control unit (150) can control the drive pump (120) to be driven until the internal pressure of the wall-forming tube (43) reaches the set maximum pressure.

[0149] At this time, the internal pressure of the wall-forming tube (43) measured by the pressure measuring sensor (112) is displayed on the display unit (144).

[0150] Meanwhile, the control unit (150) controls the driving pump (120) to drive exhaust of the wall-forming tube (43) when the pressure of the wall-forming tube (43) reaches the exhaust pressure. That is, when the internal pressure of the wall-forming tube (43) is greater than the exhaust pressure, the driving pump (120) is driven to discharge air from the inside of the wall-forming tube (43) through the air discharge port (106) provided on the other side of the main body (100a). At this time, the driving pump (120) may rotate in reverse to discharge the internal air of the wall-forming tube (43).

[0151] Accordingly, the smart blower (100) is equipped with a pressure measuring sensor (112) at the end of the pressure measuring line (114) so ​​that the user can measure the internal pressure of a large-scale wall-forming tube (43) while injecting air therein, thereby controlling the amount of air injected and discharged according to the internal pressure of the wall-forming tube (43), and preventing the injected air from leaking back out due to a backflow phenomenon caused by an increase in the internal pressure of the wall-forming tube (43), thereby enabling easy injection and discharge of air.

[0152] In addition, the smart blower (100) can operate the drive pump (120) according to the pressure value measured by the pressure measurement sensor (112), thereby preventing the air mattress from being abnormally inflated and damaged due to excessive air pressure injected through the air hose (122), and always maintaining a constant air pressure inside the wall-forming tube (43), so that users can safely use the wall-forming tube (43).

[0153] Meanwhile, the control unit (150) generates a control signal for controlling the transmission of the status of the wall-forming tube (43) to the user's smartphone (160), and can transmit the control signal to the smartphone (160) via the communication unit (130). At this time, the smartphone (160) remotely controls the driving pump (120) by transmitting or receiving the control signal so that the driving pump (120) can be remotely operated.

[0154] In this way, the smart blower according to one embodiment of the present invention measures the internal pressure of the wall-forming tube through a pressure measuring sensor, thereby controlling the amount of air injected and discharged according to the internal pressure state of the wall-forming tube, and when the internal pressure of the wall-forming tube reaches the exhaust pressure, the driving pump is driven to control the exhaust of the wall-forming tube, thereby always maintaining a constant air pressure inside the wall-forming tube, so that users can use the wall-forming tube safely.
