Embodiments for Carrying Out the Invention

[0009] Some embodiments will be described with reference to the drawings. In each embodiment, the same or similar components as those described above are denoted by the same reference numerals, and redundant detailed descriptions may be omitted as appropriate.

[0010] The hose control device disclosed in each embodiment is attached to, for example, a hose for drainage or water supply. The liquid sent from the hose is not limited to water and may be a liquid other than water. The hose control device can be used in applications such as the fire protection field, disaster prevention field, agricultural field, and industrial field.

[0011] FIG. 1 is a diagram showing an example of a schematic configuration of a drainage device 100 according to an embodiment. The drainage device 100 includes a hose control device 1, a pump 2, and a hose H. The hose control device 1 is attached to one end of the hose H. The pump 2 is attached to the other end of the hose H. The pump 2 pumps water from a water source 3 and sends the pumped water into the hose H. The water sent into the hose H passes through the hose H and is sent to the hose control device 1. The water sent to the hose control device 1 is discharged from the drain outlet of the hose control device 1 to a drainage site 4. According to the drainage device 100 having such a configuration, the water from the water source 3 can be discharged to the drainage site 4.

[0012] FIG. 2 is a diagram showing another example of the schematic configuration of the drainage device 100 according to an embodiment. The drainage device 100 includes hose control devices 1A and 1B. The hose control device 1A is located at the tip of the drainage device 100. The hose control device 1B is located between the hose control device 1A and the pump 2. The hose H connects the hose control device 1A and the hose control device 1B and the hose control device 1B and the pump 2. The water pumped up from the water source 3 by the pump 2 is sent to the hose control device 1A via the hose H and the hose control device 1B and discharged to the drainage site 4. Thus, the hose control device 1B may be arranged between the hose control device 1A provided at the tip of the drainage device 100 and the pump 2. Note that one or a plurality of hose control devices 1B may be arranged between the hose control device 1A and the pump 2.

[0013] [First Embodiment] FIG. 3 is a diagram showing a configuration example of the hose control device 1 according to the first embodiment. The hose control device 1 includes a first member 10, a second member 20, and a ballast portion BA. The hose H is attached to the first member 10. As the hose H, hoses for fire fighting, industrial use, agricultural use, etc. can be used. The ballast portion BA connects the first member 10 and the second member 20.

[0014] The hose H has a hose portion HA, a coupling portion HB, and a hose band HC. Inside the hose portion HA, a flow path through which a liquid such as water flows is formed. The coupling portion HB is provided at an end of the hose portion HA. The coupling portion HB is connected to the first member 10. The hose band HC fastens, for example, the hose portion HA and the coupling portion HB.

[0015] The first member 10 has a branch portion 10A, a coupling portion 10B, and a plurality of pipes 10C. Inside the branch portion 10A, the coupling portion 10B, and the plurality of pipes 10C, flow paths through which a liquid such as water flows are respectively formed, and the flow paths communicate with each other. Note that the number of branches of the flow path in the first member 10 is not limited to the example shown in FIG. 3.

[0016] The branch section 10A has an opening 11A (first opening). Inside the branch section 10A, for example, a cross-shaped flow path is formed that penetrates the branch section 10A, and the opening 11A is in communication with this flow path.

[0017] The coupling portion 10B is located on the opposite side of the opening 11A, with the branch portion 10A in between. The coupling portion 10B has an inlet 11B. The inlet 11B communicates with the flow path of the branch portion 10A through the flow path of the coupling portion 10B. The coupling portion 10B and the coupling portion HB have a configuration that allows them to be coupled to each other. In one example, the coupling portion 10B has the same configuration as the coupling portion HB. By coupling the coupling portion 10B and the coupling portion HB, the flow path of the first member 10 and the flow path of the hose H are connected via the inlet 11B.

[0018] Multiple pipes 10C are connected to both sides of the branch section 10A, with the branch section 10A in between. In the example shown in Figure 3, two pipes 10C are connected to both sides of the branch section 10A. Also in the example shown in Figure 3, the multiple pipes 10C have a cylindrical shape and are curved at a 90° angle toward the opening 11A. One end of each of the multiple pipes 10C is connected to the branch section 10A, and the other end of each of the multiple pipes 10C is connected to the ballast section BA. An opening 11C (first opening) is provided on the other end of each of the multiple pipes 10C. The opening 11C communicates with the flow path of the branch section 10A through the flow path of the pipe 10C.

[0019] The second member 20 has a branch section 20A, a connecting section 20B, and a plurality of pipes 20C. Inside the branch section 20A, the connecting section 20B, and the plurality of pipes 20C, flow paths for liquids such as water are formed, and these flow paths are in communication with each other. Note that the number of branching flow paths in the second member 20 is not limited to the example shown in Figure 3.

[0020] The branch section 20A has an opening 21A (second opening). Inside the branch section 20A, for example, a cross-shaped flow path is formed that penetrates the branch section 20A, and the opening 21A is in communication with this flow path.

[0021] The connecting portion 20B is located on the opposite side of the opening 21A, with the branching portion 20A in between. In one example, the connecting portion 20B has the same configuration as the connecting portion 10B and the connecting portion HB. The connecting portion 20B is provided with an outlet 21B. The outlet 21B communicates with the flow path of the branching portion 20A through the flow path of the connecting portion 20B.

[0022] As shown in Figure 1, when the hose control device 1 is positioned at the end of the drainage device 100, nothing is connected to the coupling portion 20B, as shown in the example in Figure 3. On the other hand, as shown in Figure 2, when the hose control device 1 is positioned between the hoses H, the coupling portion HB of the hose H is connected to the coupling portion 20B. When the hose control device 1 is positioned at the end of the drainage device 100, the water supplied from the hose H is drained from the outlet 21B.

[0023] Multiple pipes 20C are connected to both sides of the branch section 20A, with the branch section 20A in between. In the example shown in Figure 3, two pipes 20C are connected to both sides of the branch section 20A. Also in the example shown in Figure 3, the multiple pipes 20C have a cylindrical shape and are curved at a 90° angle toward the opening 21A. One end of each of the multiple pipes 20C is connected to the branch section 20A, and the other end of each of the multiple pipes 20C is connected to the ballast section BA. An opening 21C (second opening) is provided on the other end of each of the multiple pipes 20C. The opening 21C communicates with the flow path of the branch section 20A through the flow path of the pipe 20C.

[0024] The ballast section BA has a containment member 60A and a plurality of containment members 60C. In the example shown in Figure 3, the ballast section BA has two containment members 60C, but the number of containment members 60C is not limited to two. Inside each of the containment members 60A and 60C, a flow path is formed for a liquid such as water to flow. Here, the direction of the water flowing through the flow paths of the containment members 60A and 60C is defined as the X direction, the direction perpendicular to the X direction is defined as the Y direction, and the vertical direction is defined as the Z direction. In the example shown in Figure 3, the containment member 60A and the plurality of containment members 60C are arranged in the Y direction.

[0025] One end of each of the housing members 60A and 60C is connected to the first member 10, and the other end of each of the housing members 60A and 60C is connected to the second member 20. Specifically, housing member 60A is connected to branch sections 10A and 20A, and housing member 60C is connected to piping 10C and 20C. As a result, the flow path of the first member 10 is connected to the flow path of the housing members 60A and 60C via openings 11A and 11C, and the flow path of the second member 20 is connected to the flow path of the housing members 60A and 60C via openings 21A and 21C. In other words, the flow path of the first member 10 is connected to the flow path of the second member 20 via the ballast section BA.

[0026] The containment members 60A and 60C contain the water supplied from the first member 10. In one example, the containment members 60A and 60C are configured to expand due to the internal pressure of the water flowing inside them. For the containment members 60A and 60C, hoses such as those used for firefighting, industrial purposes, and agricultural purposes, similar to hose H, can be used. The hose may be formed in a cylindrical shape with a uniform diameter, or it may be formed in a shape with a non-uniform cross-sectional shape and cross-sectional area.

[0027] Figure 4 is a schematic cross-sectional view of the hose control device 1 according to the first embodiment. As shown in the example in Figure 4, the housing member 60C includes a jacket 61 and a liner 62 lined inside the jacket 61. The jacket 61 is formed of, for example, a fabric woven with warp and weft threads. The liner 62 is formed of, for example, a water-resistant resin. The housing member 60A is also composed of a jacket 61 and a liner 62, similar to the housing member 60C.

[0028] Furthermore, the housing members 60A and 60C can be various materials depending on the intended use of the hose control device 1, such as aluminum cans, steel pipes, or hoses formed by braiding metal.

[0029] The total area of ​​openings 11A and 11C is greater than the area of ​​inlet 11B. Also, the total area of ​​openings 21A and 21C is greater than the area of ​​outlet 21B. In the example shown in Figure 4, the areas of inlet 11B, openings 11A, 11C, 21A, 21C, and outlet 21B are all equal, but they may be different from each other.

[0030] As described above, the containment member 60A is configured to expand due to the internal pressure of the water flowing inside it. Therefore, the flow path diameter 61a in the central part of the containment member 60A is larger than the flow path diameter 61b at the ends of the containment member 60A. Similarly, in the containment member 60C, the flow path diameter in the central part of the containment member 60C is larger than the flow path diameter at the ends of the containment member 60C.

[0031] The white arrows shown in Figure 4 indicate the direction of water flow through the channels of each component. Water supplied from hose H first flows into the first component 10 via inlet 11B. Subsequently, the water that has flowed into the first component 10 is sent to the ballast section BA via openings 11A and 11C and is contained in the containment members 60A and 60C of the ballast section BA. After that, the water contained in the containment members 60A and 60C is sent to the second component 20 via openings 21A and 21C and is drained from outlet 21B.

[0032] Figure 5 shows the hose control device 1 in a state where water is not contained in the ballast section BA. If the containment member 60 is flexibly deformable, such as a fire hose, then as shown in Figure 5, when there is no water contained in the containment members 60A and 60C, the containment members 60A and 60C will be flattened.

[0033] Figure 6 is a schematic partial cross-sectional view of a configuration that can be applied to the joint 10B. The joint 10B comprises a first cylindrical portion 51 and a second cylindrical portion 52 provided on the outer circumferential surface of the first cylindrical portion 51. In this embodiment, the direction parallel to the axis AX of the joint 10B (the axis of the first cylindrical portion 51 and the second cylindrical portion 52) is called the axial direction DX, the direction away from the axis AX is called the radial direction DR, and the circumferential direction centered on the axis AX is called the circumferential direction Dθ.

[0034] The inside of the first cylindrical portion 51 forms a water flow channel. An annular sealing material 53 is provided at the end 51a of the first cylindrical portion 51.

[0035] The second cylindrical portion 52 has a plurality of hooks 54 that protrude in the axial direction DX from the end portion 51a of the first cylindrical portion 51. These hooks 54 are arranged at regular intervals in the circumferential direction Dθ. Recesses 55 are formed between adjacent hooks 54. These recesses 55 are also arranged at regular intervals in the circumferential direction Dθ, similar to the hooks 54.

[0036] The hook 54 has a first side surface 541 and a second side surface 542 in the circumferential direction Dθ. The second side surface 542 is inclined with respect to the axial direction DX. As a result, the width of the hook 54 in the circumferential direction Dθ decreases towards the tip.

[0037] The first side surface 541 is provided with a claw portion 56 protruding in the circumferential direction Dθ and a recess 57 located closer to the base of the hook 54 than the claw portion 56. The second side surface 542 is provided with a ball plunger 58. For example, the ball plunger 58 includes a hole provided in the second side surface 542, a ball housed in this hole, and an elastic body that biases the ball toward the outside of the hole. A portion of the ball protrudes from the second side surface 542.

[0038] The configuration of the connecting part HB is the same as that of the connecting part 10B. That is, the connecting part HB has a plurality of hooks 54 having the same shape as the hook 54 of the connecting part 10B, and a plurality of recesses 55 having the same shape as the recesses 55 of the connecting part 10B.

[0039] Figure 7 is a side view showing a portion of the joint portion 10B of the first member 10 and the joint portion HB of the hose H, which are joined together. When joining the joint portion 10B and the joint portion HB, the joint portion HB is pressed against the joint portion 10B with their axes AX aligned. At this time, each hook 54 of the joint portion HB is inserted into the recess 55 of the joint portion 10B, and each hook 54 of the joint portion 10B is inserted into the recess 55 of the joint portion HB.

[0040] When the joint HB is pushed as far as it will go against the joint 10B, the ball plungers 58 of both parts come into contact and push against each other, causing the joint HB to rotate slightly in the circumferential direction Dθ. At this time, the claws 56 of both parts engage and prevent them from coming loose in the axial direction DX.

[0041] Once the coupling portion 10B and coupling portion HB are coupled, the coupling state is maintained by the biasing force of the ball plunger 58. To release the coupling portion 10B and coupling portion HB, the coupling portion HB is rotated in the circumferential direction Dθ relative to the coupling portion 10B against the biasing force of the ball plunger 58. This releases the engagement of each claw portion 56.

[0042] The structures of the above-described joints 10B and HB can also be applied to the joint 20B shown in Figure 3. Furthermore, they can be used for connecting the first member 10 to the ballast section BA, and for connecting the second member 20 to the ballast section BA. Note that the method of connecting each member is not limited to the above example. For example, the joint 10B, composed of a male fitting, and the joint HB, composed of a female fitting, may be connected by engagement.

[0043] For example, if water is drained from the end of hose H without the hose control device 1 attached to the end of hose H, the end of hose H may become unstable depending on factors such as the diameter of the end of hose H, the flow rate of water flowing through hose H, and the water pressure.

[0044] In this embodiment, a hose control device 1 is attached to the end of the hose H. The water supplied from the hose H is contained in the ballast section BA. As a result, the mass of the ballast section BA increases by the mass of the water contained in the ballast section BA. This increase in the mass of the ballast section BA allows it to function as a counterweight, thereby suppressing the swaying of the hose H.

[0045] Furthermore, the mass of the ballast section BA can also be increased by increasing the number of branches in the first member 10 and the second member 20, and by increasing the number of housing members 60A and 60C. In addition, the mass of the ballast section BA can also be increased by increasing the flow path diameters 61a and 61b and lengths of the housing members 60A and 60C.

[0046] Furthermore, in this embodiment, the storage members 60A and 60C are arranged along the Y direction, which is perpendicular to the X direction in which water flows. This allows the hose control device 1 to suppress twisting of the hose H during water supply or drainage, and the rolling of the hose H caused by twisting.

[0047] Furthermore, when the structures shown in Figures 6 and 7 are applied to the connection between the first member 10 and the ballast section BA, and between the second member 20 and the ballast section BA, the first member 10, the second member 20, and the ballast section BA can be connected and separated, respectively. This allows for the transportation and storage of each component, improving the convenience of the hose control device 1. In addition, since various combinations of components are possible, the hose control device 1 can be used by rearranging the components according to the intended application and environment.

[0048] [Second Embodiment] Figure 8 shows an example of the configuration of the hose control device 1 according to the second embodiment. In addition to the first member 10, second member 20, and ballast section BA described above, the hose control device 1 according to the second embodiment further comprises a third member 30. The third member 30 is attached to the outlet 21B of the second member 20. The third member 30 has a flow path inside which the diameter increases as it moves away from the outlet 21B.

[0049] The third member 30 is connected to the joint portion 20B of the second member 20. The second member 20 and the third member 30 are connected using the connection method described above, for example, as shown in Figures 6 and 7. By connecting the third member 30 to the joint portion 20B, the flow path of the second member 20 and the flow path of the third member 30 are connected via the outlet 21B.

[0050] The third member 30 has an opening 32 (third opening). The area of ​​the opening 32 is larger than the area of ​​the outlet 21B. Water flowing out from the second member 20 flows into the third member 30 through the outlet 21B. The water that flows into the third member 30 passes through the flow path inside the third member 30 and is discharged from the opening 32.

[0051] In the second embodiment, the same effects as in the first embodiment can be obtained. In the second embodiment, the third member 30 is attached to the outlet 21B of the second member 20. Since the opening 32 of the third member 30 has a larger area than the outlet 21B, the flow velocity of water passing through the opening 32 is lower than the flow velocity of water passing through the outlet 21B. This further suppresses the turbulence of the hose H.

[0052] [Third Embodiment] Figure 9 shows an example of the configuration of the hose control device 1 according to the third embodiment. In addition to the first member 10, second member 20, and ballast section BA described above, the hose control device 1 according to the third embodiment further comprises a fourth member 40. The fourth member 40 is attached to the outlet 21B of the second member 20. The fourth member 40 has internally branched flow paths.

[0053] The fourth member 40 is connected to the joint portion 20B of the second member 20. The second member 20 and the fourth member 40 are connected using the connection method described above, for example, as shown in Figures 6 and 7. By connecting the fourth member 40 to the joint portion 20B, the flow path of the second member 20 and the flow path of the fourth member 40 are connected via the outlet 21B.

[0054] The fourth member 40 has multiple openings 42 (fourth openings). In the example shown in Figure 9, the fourth member 40 has two openings 42. The total area of ​​the multiple openings 42 is larger than the area of ​​the outlet 21B. Water flowing out from the second member 20 flows into the fourth member 40 through the outlet 21B. The water that flows into the fourth member 40 passes through the flow path inside the fourth member 40 and is discharged from the multiple openings 42.

[0055] In the third embodiment, the same effects as in the first embodiment can be obtained. In the third embodiment, the fourth member 40 is attached to the outlet 21B of the second member 20. Since the total area of ​​the multiple openings 42 of the fourth member 40 is larger than the area of ​​the outlet 21B, the flow velocity of the water passing through the multiple openings 42 is smaller than the flow velocity of the water passing through the outlet 21B. This further suppresses the turbulence of the hose H.

[0056] [Fourth Embodiment] Figure 10 shows an example of the configuration of the hose control device 1 according to the fourth embodiment. In addition to the first member 10, second member 20, and ballast section BA described above, the hose control device 1 according to the fourth embodiment further comprises a first member 15 and a second member 25.

[0057] The first member 15 has a branch section 15A, connecting sections 15B and 15D, and a plurality of pipes 15C. Inside the branch section 15A, connecting sections 15B and 15D, and the plurality of pipes 15C, flow paths for liquids such as water are formed, and these flow paths are in communication with each other.

[0058] Inside the branch section 15A, for example, a cross-shaped flow path is formed that penetrates the branch section 15A. The connecting sections 15B and 15D are provided on both sides of the branch section 15A, flanking it. The connecting section 15B has an inlet 16B. The inlet 16B communicates with the flow path of the branch section 15A through the flow path of the connecting section 15B. The connecting section 15D has an opening 16D. The opening 16D communicates with the flow path of the branch section 15A through the flow path of the connecting section 15D.

[0059] Multiple pipes 15C are connected to both sides of the branch section 15A, with the branch section 15A in between. In the example shown in Figure 10, two pipes 15C are connected to both sides of the branch section 15A. Also, in the example shown in Figure 10, the multiple pipes 15C have a cylindrical shape and are curved at a 90° angle toward the opening 16A. Furthermore, the radius of curvature of the multiple pipes 15C is larger than the radius of curvature of the multiple pipes 10C. One end of each of the multiple pipes 15C is connected to the branch section 15A, and the other end of each of the multiple pipes 15C is connected to the ballast section BA. An opening 16C (first opening) is provided on the other end side of each of the multiple pipes 15C. The opening 16C communicates with the flow path of the branch section 15A through the flow path of the pipe 15C.

[0060] The coupling portion HB of the hose H is coupled to coupling portion 15B, and the coupling portion 10B of the first member 10 is coupled to coupling portion 15D. Coupling portion 15B and coupling portion HB, and coupling portion 15D and coupling portion 10B are coupled using the coupling method described above, for example, as shown in Figures 6 and 7. When coupling portion 15B and coupling portion HB are coupled, the flow path of the first member 15 and the flow path of the hose H are connected via the inlet 16B. Similarly, when coupling portion 10B and coupling portion 15D are coupled, the flow path of the first member 10 and the flow path of the first member 15 are connected via the inlet 11B and the opening 16D.

[0061] The second member 25 has a branching section 25A, connecting sections 25B and 25D, and a plurality of pipes 25C. Inside the branching section 25A, connecting sections 25B and 25D, and the plurality of pipes 25C, flow paths for liquids such as water are formed, and these flow paths are in communication with each other.

[0062] Inside the branch section 25A, for example, a cross-shaped flow path is formed that penetrates the branch section 25A. The connecting sections 25B and 25D are provided on both sides of the branch section 25A, flanking the branch section 25A. The connecting section 25B has an outlet 26B. The outlet 26B communicates with the flow path of the branch section 25A through the flow path of the connecting section 25B. The connecting section 25D has an opening 26D. The opening 26D communicates with the flow path of the branch section 25A through the flow path of the connecting section 25D.

[0063] Multiple pipes 25C are connected to both sides of the branch section 25A, with the branch section 25A in between. In the example shown in Figure 10, two pipes 25C are connected to both sides of the branch section 25A. Also, in the example shown in Figure 10, the multiple pipes 25C have a cylindrical shape and are curved at 90° toward the opening 26A. Furthermore, the radius of curvature of the multiple pipes 15C is larger than the radius of curvature of the multiple pipes 10C. One end of each of the multiple pipes 25C is connected to the branch section 20A, and the other end of each of the multiple pipes 25C is connected to the ballast section BA. An opening 26C (second opening) is provided on the other end side of each of the multiple pipes 25C. The opening 26C communicates with the flow path of the branch section 25A through the flow path of the pipe 25C.

[0064] The joint 20B of the second member 20 is connected to the joint 25D. The joint 25D and the joint 20B are connected, for example, using the connection method described above as shown in Figures 6 and 7. By connecting the joint 20B and the joint 25D, the flow path of the second member 20 and the flow path of the second member 25 are connected via the outlet 21B and the opening 26D.

[0065] The ballast section BA has multiple housing members 65C in addition to the housing member 60A and multiple housing members 60C described above. In the example shown in Figure 10, the ballast section BA has two housing members 65C, but the number of housing members 65C is not limited to two. Multiple housing members 65C are configured in the same way as housing members 60A and 60C, and a flow path for liquid such as water is formed inside the multiple housing members 65C.

[0066] One end of the housing member 65C is connected to the first member 15, and the other end of the housing member 65C is connected to the second member 25. Specifically, one end of the housing member 65C is connected to the piping 15C, and the other end of the housing member 65C is connected to the piping 25C. As a result, the flow path of the first member 15 and the flow path of the housing member 65C are connected via the opening 16C, and the flow path of the second member 25 and the flow path of the housing member 65C are connected via the opening 26C. In other words, the flow path of the first member 15 and the flow path of the second member 25 are connected via the ballast section BA.

[0067] The containment member 65C contains the water supplied from the first member 15. In one example, the containment member 65C is configured to expand due to the internal pressure of the water flowing inside. The containment member 65C can be a hose, such as a hose H, used for firefighting, industrial purposes, or agricultural purposes. The hose may be formed in a cylindrical shape with a uniform diameter, or it may be formed in a shape with a non-uniform cross-sectional shape and cross-sectional area.

[0068] The water supplied from hose H first flows into the first member 15 via the inlet 16B. The water that flows into the first member 15 is then supplied to the first member 10 and the multiple containment members 65C. The water supplied to the first member 10 is contained in the containment members 60A and 60C, as described above, and supplied to the second member 20. The water supplied to the second member 20 is supplied to the second member 25 via the outlet 21B and opening 26D. Meanwhile, the water supplied from the first member 15 to the containment member 65C is contained in the containment member 65C and supplied to the second member 25 via opening 26C. The water supplied to the second member 25 is drained from the outlet 26B.

[0069] In the fourth embodiment, the same effects as in the first embodiment can be obtained. Furthermore, in the fourth embodiment, the ballast section BA has a housing member 65C in addition to the housing members 60A and 60C. As a result, the ballast section BA can hold more water than in the first embodiment, and its function as a weight is enhanced. This makes it possible to further suppress the movement of the hose H.

[0070] [Fifth Embodiment] Figure 11 shows an example of the configuration of the hose control device 1 according to the fifth embodiment. The hose control device 1 according to the fifth embodiment comprises a first member 10, a second member 20, and a ballast section BA.

[0071] The first member 10 has a single opening 11A (first opening) and an inlet 11B. The area of ​​the opening 11A is larger than the area of ​​the inlet 11B. The coupling portion HB of the hose H is connected to the inlet 11B. The ballast portion BA is connected to the opening 11A. The hose H and the first member 10, and the first member 10 and the ballast portion BA are connected using the coupling method described above, for example, as shown in Figures 6 and 7. The first member 10 has a flow path inside which the diameter increases from the inlet 11B toward the opening 11A.

[0072] The second member 20 has a single opening 21A (second opening) and an outlet 21B. The area of ​​the opening 21A is larger than the area of ​​the outlet 21B. The ballast section BA is connected to the opening 11A. The second member 20 and the ballast section BA are connected using the connection method described above, for example, as shown in Figures 6 and 7. The second member 20 has a flow path inside which the diameter decreases as it moves from the opening 21A towards the outlet 21B.

[0073] The ballast section BA has a single housing member 60A. One end of the housing member 60A is connected to the first member 10 via an opening 11A, and the other end of the housing member 60A is connected to the second member 20 via an opening 21A. The housing member 60A is configured in the same way as the housing members 60A and 60C described with reference to Figures 3 and 4.

[0074] Water sent from hose H to the first member 10 via inlet 11B passes through the flow path of the first member 10 and is sent to the ballast section BA via opening 11A. The water sent to the ballast section BA is then contained in the containment member 60 and sent to the second member 20 via opening 21A. The water sent to the second member 20 then passes through the flow path of the second member 20 and is drained from outlet 21B.

[0075] In the fifth embodiment, the ballast section BA has a single housing member 60. Even in this configuration, the ballast section BA functions as a weight, making it possible to suppress the swaying of the hose H.

[0076] [Sixth Embodiment] Figure 12 shows an example of the configuration of the hose control device 1 according to the sixth embodiment. The hose control device 1 according to the sixth embodiment comprises a first member 10 and a ballast section BA. The hose H and the ballast section BA are connected to the first member 10.

[0077] The first member 10 has a branch section 10A, connecting sections 10B and 10D, and a plurality of pipes 10C. Inside the branch section 10A, connecting sections 10B and 10D, and the plurality of pipes 10C, flow channels for liquids such as water are formed, and these flow channels are in communication with each other.

[0078] The branch section 10A and the connecting section 10B have the same configuration as the branch section 10A and the connecting section 10B of the first embodiment shown in Figures 3 and 4. In the example shown in Figure 12, two pipes 10C are connected to the branch section 10A. Also in the example shown in Figure 12, the multiple pipes 10C have a cylindrical shape and are curved at 90° toward the inlet 11B side. One end of each of the multiple pipes 10C is connected to the branch section 10A, and the other end of each of the multiple pipes 10C is connected to the ballast section BA. An opening 11C (first opening) is provided on the other end side of each of the multiple pipes 10C. The connecting section 10D is provided on the opposite side of the connecting section 10B, with the branch section 10A in between, and has an outlet 11D.

[0079] The ballast section BA includes a plurality of housing members 60C, a plurality of joints EL, and a housing member 60E. In the example shown in Figure 12, the ballast section BA has two housing members 60C and two joints EL, but the number of housing members 60C and joints EL is not limited to two each. The housing members 60C and 60E are configured in the same way as the housing members 60A and 60C of the first embodiment shown in Figures 3 and 4. In the example shown in Figure 12, the housing member 60C has a longer flow path than the housing member 60E and can contain more water than the housing member 60E. The joints EL have a cylindrical shape and are curved at 90°. Note that the curvature angle of the joints EL is not limited to 90°.

[0080] Both ends of the ballast section BA are attached to each of the multiple openings 11C. Specifically, one end of each of the two housing members 60C is connected to an opening 11C. The other end of each of the two housing members 60C is connected to one end of each of the two joints EL. The housing member 60E is connected to the other end of each of the two joints EL.

[0081] Water supplied from hose H first flows into the first member 10 via inlet 11B. Subsequently, a portion of the water that flows into the first member 10 is sent to the ballast section BA, and the remainder is drained from outlet 11D. The water sent to the ballast section BA passes through multiple containment members 60C and multiple joints EL before being sent to containment member 60E. As a result, water is contained in multiple containment members 60C and containment members 60E.

[0082] When water is contained in the ballast section BA, the ballast section BA is in contact with the hose H in the Z direction. In the example shown in Figure 12, the containment member 60E is in contact with the hose H in the Z direction. Alternatively, the containment member 60C may be in contact with the hose H in the Z direction. Also, in the example shown in Figure 12, the hose H is located above the containment member 60E.

[0083] For example, when water is being transported using a hose H, the water pressure flowing through the hose H can cause it to stretch, resulting in it becoming meandering. As a result, the hose H may move unintentionally.

[0084] In the sixth embodiment, the containment member 60E expands when water is contained in the ballast section BA, and the hose H is lifted by the containment member 60E. As the hose H is lifted, its expansion is released in the Z direction, thus suppressing meandering of the hose H. This makes it possible to mitigate unintended movements of the hose H. In addition, the same effects as in the first embodiment can be obtained in the sixth embodiment.

[0085] Figure 13 shows another example of the configuration of the hose control device 1 according to the sixth embodiment. In the example shown in Figure 13, the hose H is located below the housing member 60E. Therefore, a load equal to the mass of the ballast section BA and the mass of the water contained in the ballast section BA is applied to the hose H. This makes it possible to further suppress the swaying of the hose H.

[0086] [Seventh Embodiment] Figure 14 shows an example of the configuration of the hose control device 1 according to the seventh embodiment. The ballast section BA of the hose control device 1 according to the seventh embodiment has a plurality of housing members 60C and a plurality of caps CP. In the example shown in Figure 14, the ballast section BA has two housing members 60C and two caps CP, but the number of housing members 60C and caps CP is not limited to two. One end of each of the plurality of housing members 60C is connected to the opening 11C. The other end of each of the plurality of housing members 60C is sealed by a cap CP.

[0087] In the seventh embodiment, water is contained in a plurality of containment members 60C whose ends are sealed by caps CP, and the ballast section BA functions as a weight. This suppresses the swaying of the hose H. The ends of the containment members 60C may be sealed by sewing, adhesive, or other means. In addition, the same effects as in the first embodiment can be obtained in the seventh embodiment.

[0088] Figure 15 shows another example of the configuration of the hose control device 1 according to the seventh embodiment. In the example shown in Figure 15, the ballast section BA is connected to the branch section 10A of the first member 10. Specifically, the housing member 60C is connected to the opening 11A (first opening) provided in the branch section 10A.

[0089] In the example shown in Figure 15, the axis passing through the center of the opening 11A is perpendicular to the axis passing through the center of the outlet 11D. Therefore, the containment member 60C extends in a direction (X direction) perpendicular to the direction (Y direction) in which water is discharged from the outlet 11D. This allows the hose control device 1 to suppress twisting of the hose H during water supply or drainage, and the rolling of the hose H caused by twisting.

[0090] Figure 16 shows yet another configuration example of the hose control device 1 according to the seventh embodiment. In the example shown in Figure 16, another first member 10 to which a ballast section BA is connected is connected to the outlet 11D side of the first member 10 shown in Figure 15. In this way, the number of housing members 60C can be increased by connecting multiple first members 10. This makes it possible for the hose control device 1 to further suppress twisting of the hose H during water supply or drainage, and the rolling of the hose H caused by twisting.

[0091] [Eighth Embodiment] Figure 17 shows an example of the configuration of the hose control device 1 according to the eighth embodiment. The hose control device 1 according to the eighth embodiment includes a first member 10, a ballast section BA, a plurality of pipes PP, and a plurality of fasteners CH.

[0092] The first member 10 has a joint portion 12 and connecting portions 10B and 10D. The joint portion 12 is formed in a cylindrical shape. The connecting portions 10B and 10D are provided on both sides of the joint portion 12, flanking it. The connecting portions 10B and 10D have a configuration similar to, for example, the connecting portions 10B and 10D of the sixth embodiment.

[0093] The ballast section BA has multiple housing members 60C, 60E and multiple joints EL. In the example shown in Figure 17, the ballast section BA has two housing members 60C, two housing members 60E, and four joints EL, but the number of housing members 60C, 60E and joints EL is not limited to this. One end of each of the multiple joints EL is connected to one end of each of the multiple housing members 60C, and the other end of each of the multiple joints EL is connected to the other end of each of the multiple housing members 60E. In the example in Figure 17, the first member 10 is in contact with the multiple housing members 60C.

[0094] Multiple pipes PP connect the first member 10 and the ballast section BA. In the example shown in Figure 17, multiple pipes PP connect the joint section 12 and the joint EL. Alternatively, multiple pipes PP may connect the joint section 12 to the housing members 60C and 60E. The joint section 12 and the joint EL are provided with openings that communicate with the flow paths within the multiple pipes PP.

[0095] In the example shown in Figure 17, there are four pipes made of polypropylene (PP). However, the number of pipes is not limited to this; for example, there may be one. The pipes made of polypropylene (PP) can be, for example, flexible hoses or pipes made of metal or resin.

[0096] Multiple fasteners CH connect the first member 10 to the ballast section BA. In the example shown in Figure 17, multiple fasteners CH connect the joint section 12 to the joint EL. Also, in the example shown in Figure 17, there are four fasteners CH. However, the number of fasteners CH is not limited to this. Fasteners CH can be made of metal chains, for example.

[0097] The water supplied from hose H first flows into the first member 10 via inlet 11B. Subsequently, a portion of the water that flows into the first member 10 is sent to the ballast section BA through piping PP, and the remainder is drained from outlet 11D. The water sent to the ballast section BA is then sent to the containment members 60C and 60E via joint EL. As a result, water is contained in the containment members 60C and 60E.

[0098] In the eighth embodiment, the first member 10 and the ballast section BA are connected by piping PP. Water sent from hose H to the first member 10 passes through piping PP and is contained in the ballast section BA. As a result, the ballast section BA functions as a weight, suppressing the movement of hose H. Thus, the first member 10 and the ballast section BA do not necessarily have to be directly connected.

[0099] Furthermore, the first member 10 is fixed to the ballast section BA by a fixing device CH. This increases the stability of the posture of the first member 10, making it possible to further suppress the movement of the hose H. In addition, the same effects as in the first embodiment can be obtained in the eighth embodiment as well.
