Description

[Technical field]

[0001] The present invention relates to a mud recovery container, and more particularly to a mud recovery container used when recovering mud that has accumulated under the floor of a building. [Background technology]

[0002] In the past, flooding occurred due to typhoons and torrential rains, and buildings such as houses experienced flooding under or above the floor. River water or rainwater that entered under the floor contains fine particles of mud from the surrounding area, and it became necessary to remove the mud (muddy water) that had accumulated under the floor, but this work was very hard work. For this reason, a mud recovery system is known that uses a suction device such as a vacuum cleaner to recover mud that has accumulated under the floor of a building.

[0003] Specifically, the mud recovery system is installed outdoors, with a suction device (the main body of the suction device) and a large mud recovery container connected by a hose. The hose is then extended from the outdoors of the building to underneath the floor inside the building, and the mud recovery head at the end of the hose is operated to suck up the mud that has accumulated underneath the floor. The sucked up mud is then collected in the mud recovery container. For example, Patent Document 1 proposes a sludge recovery device for efficiently recovering sludge that has accumulated in a specified area, although it is not intended to be used for recovering mud that has accumulated under the floors of a building.

[0004] [Patent Document 1] JP 2014-125754 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in a mud recovery system used to recover mud accumulated under the floors of buildings, it is difficult to install a large suction device or a mud recovery container near the building. In particular, during a disaster, there are many damaged objects, so it is even more difficult to install a large suction device or a mud recovery container near the building. If the suction device or the mud recovery container is installed away from the building, the hose becomes long and handling of the hose can become complicated. In addition, when sucking up and recovering mud accumulated under the floors of buildings, the suction force (suction pressure) of the suction device needs to be set high, making it difficult to use a general suction device. For this reason, there has been a demand for technology that can collect mud accumulated under the floor with a simpler configuration than before.For example, there has been a demand for technology that can suck up mud from under the floor and collect it in a mud collection container even when using a relatively small suction device (vacuum cleaner).

[0006] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a mud collection container that is capable of collecting mud that has accumulated under the floor with a simpler configuration than conventional containers. Another object of the present invention is to provide a mud recovery container that is used in a mud recovery system and contributes to making the suction device smaller and facilitating the handling of the hose. [Means for solving the problem]

[0007] The above problem is solved by the mud recovery container of the present invention, which is used when recovering mud accumulated under the floor of a building and recovers the mud sucked up by a suction device, the mud recovery container being installed under the floor of the building and collecting the mud inside, a first joint part attached to the container body and connected to a first hose that transports the mud and passes the mud from the first hose to the inside of the container body, and a second joint part attached to the container body and connected to a second hose that transports air in the container body and passes the air from the inside of the container body to the second hose, the mud recovery container recovers the mud inside by discharging the air in the container body through the second hose by the suction action of the suction device, and sucking up the mud through the first hose, the first joint part is attached to the side or upper part of the container body, and of the first joint part, a hose connection part that connects the first hose protrudes horizontally outward from the container body.

[0008] With the above configuration, it is possible to realize a mud recovery container that is capable of recovering mud accumulated under the floor with a simpler configuration than conventional ones. More specifically, the mud recovery container is installed under the floor of the building, which shortens the length of the hose compared to when the mud recovery container is installed outdoors, thereby contributing to the realization of a mud recovery system with a simple configuration. In addition, since the mud recovery container is installed under the floor, there is no need to pump up mud from under the floor, and the suction force of the suction device can be set to be small. For example, a general suction device can be used. In addition, the first joint part of the mud recovery container is attached to the side or upper part of the container body, and the hose connection part of the first joint part for connecting the first hose protrudes horizontally outward from the container body. This makes it possible to lower the lifting height (suction lifting height) when sucking mud accumulated under the floor into the mud recovery container, so that even if the suction force of the suction device is set relatively low, the mud can be suitably collected in the mud recovery container.

[0009] In this case, it is preferable that the first fitting portion is attached by penetrating through the side portion of the container body, the hose connection portion of the first fitting portion protrudes horizontally outward from the side portion of the container body, and a fitting outlet of the first fitting portion provided inside the container body faces horizontally inward or downward inside the container body. As described above, the first joint part is attached by penetrating into the side part of the container body, and the hose connection part of the first joint part protrudes horizontally outward from the side part of the container body, so that the lift height (suction lift height) can be set lower when sucking mud accumulated under the floor into the mud collection container, thereby making it possible to more efficiently collect mud in the mud collection container. In addition, since the height of the mud collection container can be reduced, it becomes easier to install the mud collection container under the floor of a building.

[0010] In this case, the second joint part is attached by penetrating through a side part of the container body other than the side part to which the first joint part is attached, the second joint part has a curved shape, and a joint inlet of the second joint part provided inside the container body faces upward inside the container body. With the above configuration, the air inside the container body can be suitably discharged when sucked by the suction device. For example, if the joint inlet of the second joint part faces horizontally or downward, there is a risk that the mud collected in the container body may be sucked in, or the mud collection bag in which the mud is collected may be unintentionally sucked in.

[0011] In this case, a bag-shaped mud recovery bag is provided inside the container body to recover the mud that has been sucked into the container body, and the mud recovery bag is connected to a joint outlet of the first joint part that is provided inside the container body, and is arranged so as to extend along the horizontal direction of the container body. With the above-mentioned configuration, the mud sucked into the inside of the container body can be efficiently collected in the mud collection bag. Furthermore, after a certain amount of mud has been collected, the mud collection bag can be removed and carried. Furthermore, by arranging the first joint portion and the mud collection bag as described above, the height of the mud collection container can be reduced.

[0012] In this case, a third joint portion is provided inside the container body, connected to the mud collection bag, and discharging air inside the mud collection bag inside the container body to the outside of the mud collection bag, and it is preferable that the joint outlet of the third joint portion, which is provided on the outside of the mud collection bag, faces upward inside the container body. By providing the third joint portion as described above, the air in the mud collection bag can be suitably discharged inside the container body, and the suction operation of the suction device can be smoothly performed to suck up the mud. Furthermore, as described above, since the joint outlet of the third joint portion faces upward inside the container body, it is possible to prevent mud collected in the mud collection bag from flowing out to the outside through the third joint portion (the mud can be suitably trapped in the mud collection bag).

[0013] In this case, it is preferable that the first joint portion and the third joint portion are arranged side by side, the joint outlet of the first joint portion and the joint inlet of the third joint portion are connected to a bag opening of the mud recovery bag, and the joint outlet of the first joint portion is connected so as to penetrate deeper into the mud recovery bag than the joint inlet of the third joint portion within the mud recovery bag. By arranging the first joint portion and the second joint portion as described above, the mud recovery container can be made smaller. As described above, the joint outlet of the first joint is connected to be deeper into the mud collection bag than the joint inlet of the third joint, which further prevents the mud collected in the mud collection bag from flowing out through the third joint.

[0014] In this case, the mud recovery container is provided with a lid portion that covers the container body from above, and the mud recovery container recovers the mud inside while creating a vacuum inside the container body by the suction action of the suction device, and the first joint portion and the second joint portion are preferably positioned below the lid portion and do not protrude above the lid portion. As described above, by creating a vacuum inside the mud recovery container, the suction device can smoothly suck up the mud, and the mud can be suitably collected in the mud recovery container. Furthermore, with the above-described configuration, the height of the mud recovery container can be reduced, making it easier to install it under the floor. Effect of the Invention

[0015] According to the mud recovery container of the present invention, it is possible to recover mud that has accumulated under the floor with a structure simpler than that of the conventional device. Furthermore, the mud recovery container of the present invention contributes to the miniaturization of the suction device in the mud recovery system and makes it easier to handle the hose.

[Diagram 5] FIG. 11 is a side cross-sectional view of a mud recovery container according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described with reference to FIGS. This embodiment relates to a "mud recovery container" that is used to recover mud that has accumulated under the floor of a building, and that collects the mud sucked up by a suction device, making it possible to recover mud that has accumulated under the floor with a simpler configuration than conventional containers.

[0018] <Mud recovery system> As shown in Figure 1, the mud recovery system S is used when flooding occurs due to a typhoon, heavy rain, etc., and water reaches under or above the floor of a building B, such as a house. More specifically, the mud recovery system S is used to efficiently recover mud M (which may be muddy water) that has accumulated in the underfloor B2 (underfloor space) located under the floor B1 of the building B. "Flooding above the floor" refers to a state in which the water is above the floor of a building (home) and exceeds 45cm above ground level. "Flooding below the floor" refers to a state in which the water is below the foundation of a building and not more than 45cm above ground level. For example, by law, the height of a building floor must be at least 45cm from the ground directly below it to the top of the floor.

[0019] Specifically, the mud recovery system S is mainly composed of a mud recovery container 1 installed under the floor B2 of building B, and a generator 100 and a suction device 200 (device main body 210) each installed outdoors of building B. The mud recovery container 1 is connected to a mud recovery head 240 via a first hose 220 , and is also connected to a suction device 200 (device body 210 ) via a second hose 230 . The suction device 200 is connected to the generator 100 through a power cord 110 . First, the generator 100 and the suction device 200 will be described.

[0020] The generator 100 is a device that generates electricity by, for example, electromagnetic induction and supplies the electricity to the suction device 200. The generator 100 is installed outside the building B. The suction device 200 is also called a vacuum device, and is a device that receives electricity from the generator 100 to perform a suction operation. The suction device 200 comprises an apparatus main body 210 installed outdoors of building B, a first hose 220 connecting the apparatus main body 210 and the mud recovery container 1, and a second hose 230 connecting the mud recovery container 1 and the mud recovery head 240.

[0021] The first hose 220 and the second hose 230 are transfer hoses (transfer pipes) for transferring air and mud M (muddy water). The first hose 220 is a hose for mainly passing mud accumulated under the floor B2. The second hose 230 is a hose for mainly discharging air from the mud recovery container 1. 1, the first hose 220 is disposed under the floor B2 of the building B and extends along the under floor B2. The second hose 230 passes from the under floor B2 of the building B through an under floor opening B3 and extends from the inside of the building B to the outside. The mud recovery head 240 is connected to the tip of the first hose 220, and is a hollow head member that sucks up the mud M that has accumulated under the floor B2 as the device main body 210 performs a suction operation.

[0022] In the above configuration, as shown in Fig. 1, in the mud recovery system S, a small mud recovery container 1 is installed under the floor B2 of a building B. Therefore, compared to the conventional case where a large mud recovery container (a drum-type mud recovery container) is installed outside the building B, the hose routing can be shortened, and a simple configuration can be realized. In addition, by installing the mud recovery container 1 under the floor, there is no need to pump up the mud M from under the floor B2 as in the past, and the suction power of the suction device 200 can be set to a small value. For example, it is possible to use a home suction device (voltage 100V specification) instead of a commercial suction device (voltage 200V specification).

[0023] As shown in Figures 1 to 3, the mud recovery container 1 is a container (sealed container) with a rectangular cross section, and has a size that allows it to be installed under the floor B2 of the building B. For example, it has a height of about 30 to 40 cm so that it can fit under the floor B2, and a length of about 40 to 50 cm in both length and width so that it can pass through the underfloor opening B3. The mud recovery container 1 can recover mud M inside by exhausting air from within the container body 10 through the second hose 230 through the suction action of the suction device 200 and sucking in mud M through the first hose 220.

[0024] The mud collection container 1 comprises a container body 10 for collecting mud M inside, a lid portion 20 for covering the container body 10 from above, a first joint portion 30 attached to the side portion of the container body 10 and connected to a first hose 220, a second joint portion 40 connected to a second hose 230, and a third joint portion 50 and a mud collection bag 60 attached inside the container body 10. The mud recovery container 1 has a lid 20 attached to the upper end of the container body 10 via a packing 11, thereby forming an enclosed space for collecting the mud M. The mud recovery container 1 recovers the mud M inside while creating a vacuum state (low vacuum state) inside the container body 10 by the suction operation of the suction device 200.

[0025] The materials of the container body 10 and the lid 20 are not particularly limited, but may be made of a resin material to reduce weight. The first joint 30, the second joint 40, and the third joint 50 may also be made of a resin material or a metal material such as aluminum to reduce weight.

[0026] 2 and 3, the first joint part 30 is a joint that connects the container body 10 and the first hose 220 and mainly passes mud M from the first hose 220 to the container body 10. The first joint part 30 may also be called a connecting part, a connection part, or a pipe. The first joint part 30 is attached to the side part 10a of the container body 10 by penetrating therethrough, and of the first joint part 30, a hose connection part 32 to which the first hose 220 is connected protrudes horizontally outward from the container body 10.

[0027] The first fitting part 30 has a fitting body 31 attached to the side part 10a of the container body 10, a hose connection part 32 protruding horizontally outward from the fitting body 31, and a bag connection part 33 protruding from the fitting body 31 into the inside of the container body 10 and connected to the mud collection bag 60. A joint inlet 32 ​​a at the tip of the hose connection part 32 faces horizontally outward when viewed from the container body 10 . The bag connection part 33 extends horizontally inward inside the container body 10, and a joint outlet 33a at the tip of the bag connection part 33 faces horizontally inward inside the container body 10.

[0028] 2, the second joint part 40 is a joint that connects the container body 10 and the second hose 230 and mainly discharges air from inside the container body 10 to the second hose 230. The second joint part 40 is made of an L-shaped body and is also called an elbow joint or elbow piping. The second joint part 40 is attached to, penetrating, a side part 10b of the container body 10 opposite to the side part 10a to which the first joint part 30 is attached. Of the second joint part 40, a hose connection part 43 for connecting the second hose 230 protrudes horizontally outward from the container body 10.

[0029] The second joint part 40 has a joint body 41 attached to the side part 10b of the container body 10, a container connection part 42 protruding from the joint body 41 into the inside of the container body 10, and a hose connection part 43 protruding horizontally outward from the joint body 41. The container connection part 42 has a bent shape, and a joint inlet 42a at the tip of the container connection part 42 faces upward inside the container body 10. A joint outlet 43a at the tip of the hose connection part 43 faces horizontally outward when viewed from the container body 10.

[0030] 2 and 3, the third joint part 50 is a joint part that connects the container body 10 and the mud recovery bag 60 and mainly discharges air inside the mud recovery bag 60 in the internal space of the container body 10 to the outside of the mud recovery bag 60. The third joint part 50, like the second joint part 40, is made of an L-shaped body. The third joint part 50 is disposed so as to be vertically aligned with the first joint part 30 within the container body 10. The third joint part 50 may be disposed so as to be horizontally aligned with the first joint part 30 within the container body 10.

[0031] The third joint part 50 has a joint body 51 having an L-shape (bent shape), a bag connection part 52 extending from the joint body 51 along the first joint part 30, and a container connection part 53 extending upward from the joint body 51 inside the container body 10. A joint inlet 52a at the tip of the bag connecting part 52 extends into the inside of the mud recovery bag 60. A joint outlet 53a at the tip of the container connecting part 53 faces upward inside the container body 10.

[0032] 2 and 3, the mud collection bag 60 is a sandbag for collecting the mud M sucked into the inside of the container body 10. The mud collection bag 60 may be a bag made of hemp material or a bag made of a resin material such as polyethylene. The mud recovery bag 60 is detachably provided inside the container body 10, and after a certain amount of mud M is collected in the mud recovery bag 60, it is replaced with another mud recovery bag. The bag opening 61 of the mud recovery bag 60 is connected to the joint outlet 33a of the first joint part 30 and the joint inlet 52a of the third joint part 50. In addition, the bag body 62 of the mud recovery bag 60 is arranged to extend along the horizontal direction of the container body 10.

[0033] In the above configuration, as shown in Figure 2, the joint outlet 33a of the first joint part 30 is connected so as to enter the mud recovery bag 60 deeper inside the mud recovery bag 60 than the joint inlet 52a of the third joint part 50. This makes it possible to prevent the mud M collected in the mud collection bag 60 from flowing out to the outside through the third joint portion 50.

[0034] In the above configuration, as shown in FIG. 2, the first joint part 30 is attached to the side part of the container body 10, and the hose connection part 32 of the first joint part 30 protrudes horizontally outward from the container body 10. By doing so, the lift height (suction lift height) can be lowered when sucking the mud M accumulated under the floor into the mud recovery container 1. Therefore, even if the suction force of the suction device 200 is set relatively low, the mud M can be suitably collected in the mud recovery container 1.

[0035] In the above configuration, the first joint part 30 and the second joint part 40 are disposed below the lid part 20 and are disposed so as not to protrude above the lid part 20, as shown in FIG. By doing so, the height of the mud recovery container 1 can be lowered, making it easier to install it under the floor B2 of the building B.

[0036] The above-described mud recovery system S (mud recovery container 1) can recover the mud M accumulated under the floor B2 with a simple configuration. In particular, the suction device 200 can be made compact, and the hoses 220, 230 can be easily handled. In addition, the mud recovery container 1 can be made compact and installed under the floor B2. In addition, since the mud M that accumulates under the floor B2 contains many fine particles and a mud recovery container 1 is installed under the floor B2, by using the above-mentioned mud recovery system S, a household suction device 200 (100V specification) with a relatively low suction pressure can be used. By using a small suction device 200 and a small mud recovery container 1, it can be easily transported by a light truck. Cleaning work can be performed efficiently, and the labor cost of manufacturing work can be set low.

[0037] <Mud recovery container of second embodiment> Next, a mud recovery container 1A according to a second embodiment will be described with reference to FIG. It should be noted that the description overlapping with that of the mud recovery container 1 described above will be omitted.

[0038] The mud recovery container 1A includes a container body 10A having a generally rectangular cross section, a lid portion 20A, a first joint portion 30A, a second joint portion 40A, a third joint portion 50A, and a mud recovery bag 60A. The mud recovery container 1A recovers the mud M therein while creating a vacuum state inside the container body 10A by the suction action of the suction device. A recess 11A is formed in an upper portion 10Ab (corner portion) of one end portion in the longitudinal direction of the container body 10A.

[0039] The first joint part 30A is attached to the upper part 10Ab of the container body 10A by penetrating therethrough, and a hose connection part 32A of the first joint part 30A protrudes outward from the container body 10A. Specifically, the first joint portion 30A has a bent shape and is attached to the upper surface of the recessed portion 11A in the upper portion of the container body 10A by penetrating therethrough.

[0040] The first joint part 30A has a joint body 31A that is attached to the upper part 10Ab of the container body 10A, a hose connection part 32A that protrudes outward from the joint body 31A, and an L-shaped bag connection part 33A that protrudes from the joint body 31A into the inside of the container body 10A and connects to the mud collection bag 60A. The hose connection part 32A may have an L-shape and protrude horizontally outward. In this case, the joint inlet 32Aa at the tip of the hose connection part 32A faces horizontally outward when viewed from the container body 10A. The bag connecting part 33A extends horizontally inward inside the container body 10A. A joint outlet 33Aa at the tip of the bag connecting part 33A faces horizontally inward inside the container body 10A.

[0041] The third joint part 50A has an L-shape, and is disposed in a state supported by the first joint part 30A (hose connection part 32A) and the container body 10A (recessed part 11A). Specifically, the third joint part 50A is placed on the upper surface of the first joint part 30A (hose connection part 32A) and is disposed in a state of abutting against the inner wall surface of the container body 10A (recessed part 11A).

[0042] Even in the above-mentioned mud collection container 1A, as shown in FIG. 4, the first joint part 30A and the second joint part 40A are positioned below the lid part 20A and are positioned so as not to protrude above the lid part 20A. By doing so, the height of the mud recovery container 1A can be lowered, making it easier to install it under the floor B2 of the building B. In addition, the lift height can be made relatively low when sucking the mud M accumulated under the floor into the mud recovery container 1A.

[0043] <Mud recovery container of the third embodiment> Next, a mud recovery container 1B according to a third embodiment will be described with reference to FIG. It should be noted that explanations of the contents overlapping with those of the mud recovery containers 1 and 1A described above will be omitted.

[0044] The mud collection container 1B includes a container body 10B having a rectangular cross section, a lid portion 20B, a first joint portion 30B, a second joint portion 40B, and a mud collection tray 60B. The mud recovery container 1B recovers the mud M therein while creating a vacuum state inside the container body 10B by the suction action of the suction device.

[0045] The first joint portion 30B has a joint body 31B, a hose connecting portion 32B, and an L-shaped tray connecting portion 33B. A joint outlet 33Ba at the tip of the tray connecting portion 33B faces downward inside the container body 10B.

[0046] The mud collection tray 60B is installed at the bottom of the container body 10B, and is disposed at a lower position than the first joint part 30B and the second joint part 40B. The mud collection tray 60B is detachably provided within the container body 10B, and after a certain amount of mud M has been collected in the mud collection tray 60B, it is replaced with another mud collection tray.

[0047] Even in the above-mentioned mud collection container 1B, as shown in FIG. 5, the first joint part 30B and the second joint part 40B are positioned below the lid part 20B and are positioned so as not to protrude above the lid part 20B. This allows the height of the mud recovery container 1B to be lowered, making it easier to install it under the floor B2 of the building B. In addition, the lift height can be made relatively low when sucking the mud M accumulated under the floor into the mud recovery container 1B.

[0048] <Other embodiments> In the above embodiment, as shown in Fig. 2, the mud recovery container 1 is provided with the mud recovery bag 60, but this is not particularly limited and can be modified. For example, the mud recovery bag 60 may be omitted. In that case, the mud M may be collected at the bottom of the mud recovery container 1. Similarly, as shown in Fig. 5, the mud recovery container 1B is provided with a mud recovery tray 60B, but the mud recovery tray 60B may be omitted. In that case, the mud M may be stored at the bottom of the mud recovery container 1B.

[0049] In the above embodiment, as shown in FIG. 2, the mud recovery container 1 has a first joint portion 30, a second joint portion 40, and a third joint portion 50, but the shapes of these joint portions are not particularly limited and can be changed. Preferably, for the first joint part 30, the hose connection part 32 faces sideways or downwards in order to suitably transfer the mud M into the mud recovery container 1. For the second joint part 40, the container connection part 42 faces upwards in order to suitably exhaust the air inside the mud recovery container 1 to the outside. For the third joint part 50, the container connection part 53 faces upwards in order to improve air circulation inside the mud recovery container 1.

[0050] In the above embodiment, the mud recovery container according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof. In particular, the above-described embodiment is merely an example and does not limit the present invention. [Explanation of symbols]
