Description

Technical Field

[0005]

[0001] The present invention relates to a mud collection container and a mud collection system, and particularly to a mud collection container and a mud collection system used when collecting mud accumulated under the floor of a building.

Background Art

[0002] Conventionally, floods have occurred due to typhoons, heavy rainstorms, etc., and floor flooding or upper floor flooding has occurred in buildings such as houses. The river water and rainwater that have invaded under the floor contain fine particles of neighboring mud, and it is necessary to remove the mud (muddy water) accumulated under the floor, but this work is extremely laborious. Therefore, a mud collection system for collecting mud accumulated under the floor of a building using a suction device such as a vacuum cleaner is known.

[0003] Specifically, as a mud collection system, it is installed in a state where a suction device (the main body of the suction device) and a large mud collection box are connected by a hose outside the building. Then, the hose is extended from outside the building to under the floor inside the building, and the mud collection head at the tip of the hose is operated to suck the mud accumulated under the floor. The sucked mud is collected in the mud collection box. For example, Patent Documents 1 and 2 propose a sludge collection device for collecting sludge staying in a predetermined area, although it is not used for collecting mud accumulated under the floor of a building.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, in mud recovery systems used to collect mud accumulated under the floors of buildings, it was difficult to install large suction devices and mud recovery containers near the building. Installing suction devices and mud recovery containers far from the building sometimes made handling the hoses cumbersome. Also, when sucking up and collecting mud accumulated under the floors of buildings, it was necessary to set the suction power of the suction device to a high level, making it difficult to use general-purpose suction devices. Therefore, there was a need for a technology that could collect mud accumulated under the floor with a simpler configuration than before. For example, even when using a relatively small suction device (vacuum cleaner), it was required to be able to suck up mud from under the floor and collect it in a mud collection container.

[0006] In addition, it is envisioned that small mud collection containers will be installed under or near the floor of the building to temporarily collect mud. In such cases, when connecting the mud collection head, the small mud collection container, and the suction device, it was necessary to devise a way to prevent the suction device from sucking up mud along with the air inside the mud collection container.

[0007] The object of the present invention is to provide a mud collection container and a mud collection system that can collect mud accumulated under the floor with a simple configuration. Another object of the present invention is to provide a mud collection container and a mud collection system that can suitably collect mud accumulated under the floor when a mud collection container is installed under the floor of a building. [Means for solving the problem]

[0008] The aforementioned problem is solved by the mud collection container of the present invention, which is used when collecting mud accumulated under the floor of a building and is used to collect the mud sucked up by a suction device, comprising: a container body for collecting the mud inside; a first connection part provided on the first side of the container body and connected to a first hose for transporting the mud, allowing the mud to pass from the first hose into the interior of the container body; and a second connection part provided on a second side of the container body different from the first side, and connected to a second hose for transporting air inside the container body, allowing the air to pass from the interior of the container body into the second hose, wherein a mud discharge port provided inside the container body of the first connection part and an air intake port provided inside the container body of the second connection part are arranged at diagonal positions in a top view or side view.

[0009] The above configuration makes it possible to create a mud collection container that can collect mud accumulated under the floor with a simple design. More specifically, the mud collection container can be placed under or near the floor of the building. This simplifies the routing of hoses compared to conventional systems (allowing for shorter hose lengths). Furthermore, when pumping mud from under the floor, the suction force of the suction device can be set to a lower level. For example, a smaller suction device can be used. This enables the realization of a mud collection system with a simple configuration. Furthermore, the above-mentioned mud collection container comprises a container body, a first connection part for passing mud, and a second connection part for passing air. The mud discharge port of the first connection part and the air intake port of the second connection part are positioned diagonally opposite each other in a top or side view. In other words, the mud discharge port and the air intake port are not facing each other inside the container body and are positioned at a distance from each other. This prevents (or minimizes) the suction device from sucking in mud along with the air inside the mud collection container. In other words, it is possible to realize a mud collection system that can suitably collect mud accumulated under the floor.

[0010] In this case, the mud collection container is installed under or near the floor of the building, and the mud is collected inside the container by the suction operation of the suction device, which discharges the air inside the container body through the second hose and sucks the mud through the first hose, and it is preferable that the mud discharge port and the air intake port are positioned diagonally opposite each other in a top view and a side view. As described above, by positioning the mud discharge port and air intake port diagonally opposite each other in top and side views, it is possible to further prevent the suction device from sucking up mud along with the air inside the mud collection container.

[0011] In this configuration, the first and second connecting portions are connected to the side of the container body along one of the longitudinal and width directions of the container body, and the mud discharge port and the air intake port are positioned diagonally opposite each other in a top view, and in a top view, they face opposite each other in a direction that intersects the connection direction of the first and second connecting portions. Furthermore, the mud discharge port is preferably oriented diagonally downward or sideways within the container body, and the air intake port is preferably oriented sideways or diagonally upward within the container body. With the above configuration, the mud discharge port and the air intake port can be positioned at different locations and orientations within the container body, and spaced apart from each other. This allows mud to be suitably accumulated in the mud collection container through the first connection part (mud discharge port). In addition, air can be suitably drawn in from inside the mud collection container through the second connection part (air intake port). For example, even if the suction force of the suction device is increased, it is possible to prevent unintentional sucking in of mud from inside the mud collection container.

[0012] In this case, the first connecting portion extends within the container body in a direction intersecting the connection direction of the first connecting portion, is provided at the extended end of the first connecting portion, is formed in continuity with the mud discharge port, and has a first notch portion arranged to face the first side portion, and the second connecting portion extends within the container body in a direction intersecting the connection direction of the second connecting portion, is provided at the extended end of the second connecting portion, is formed in continuity with the air intake port, and has a second notch portion arranged to face the second side portion. As described above, by forming the first and second notches, mud can be efficiently discharged from inside the container body, and air can be efficiently drawn in.

[0013] In this case, the container body is provided with a partition plate located on the upper or side of the container body and positioned between the mud discharge port and the air intake port inside the container body, and it is preferable that the partition plate be positioned at the same height as at least one of the first connection portion and the second connection portion. As described above, by placing a partition plate between the mud discharge port and the air intake port, it is possible to prevent the suction device from directly sucking up the mud discharged into the mud collection container. In addition, even if the mud discharged from the mud discharge port splashes back, the partition can be used to prevent the splashed mud from entering the air intake port.

[0014] Furthermore, the aforementioned problems are solved by the mud recovery system of the present invention, which comprises a mud recovery container, a mud recovery head connected to the mud recovery container via a first hose for recovering mud accumulated under the floor, a suction device connected to the mud recovery container via a second hose, a discharge pump provided in the mud recovery container for discharging the mud recovered in the mud recovery container, a mud detection unit provided in the mud recovery container for detecting when the amount of mud recovered in the mud recovery container reaches or exceeds a predetermined amount, and a mud recovery box connected to the discharge pump via a third hose, which is larger than the mud recovery container and stores the mud inside, wherein the suction device and the mud recovery box are located outside the building. With the above configuration, for example, based on the detection result of the mud detection unit, the ON / OFF operation of the suction device and the ON / OFF operation of the discharge pump can be performed. That is, mud can be efficiently recovered.

[0015] At this time, the discharge pump and the mud detection unit are arranged inside the mud recovery container, provided inside the mud recovery container, and provided with a pump cover arranged so as to surround the discharge pump and the mud detection unit. A mud passage port for passing the mud is formed in a side portion of the pump cover, and it is preferable that the mud passage port is arranged at a position lower than the mud detection unit. As described above, by providing the pump cover, the mud detection unit can accurately detect the recovery amount of the mud recovered in the mud recovery container, and the mud accumulated in the mud recovery container can be transferred to the mud recovery box. For example, when mud is discharged from the mud discharge port inside the container body, waves will occur on the surface of the mud accumulated in the container body (the water surface of the muddy water), and the mud detection unit may not be able to appropriately detect the water surface of the muddy water. Therefore, by covering the mud detection unit and the discharge pump with the pump cover, the water surface of the muddy water can be stabilized (the rippling of the water surface can be suppressed) inside the pump cover. Thereby, the mud detection unit can accurately detect the recovery amount of the mud. It is preferable that the mud passage port of the pump cover is arranged at a position lower than the mud detection unit.

Effect of the Invention

[0016] According to the mud recovery container and the mud recovery system of the present invention, it is possible to recover the mud accumulated under the floor with a simple configuration. In addition, when the mud recovery container is installed under the floor of a building, it is possible to preferably recover the mud accumulated under the floor.

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 11. This embodiment relates to a "mud recovery container" that is used when recovering mud accumulated under the floor of a building and can preferably recover the mud accumulated under the floor when a mud recovery container is installed under the floor. It also relates to a "mud recovery system" equipped with a mud recovery container.

[0019] <Mud Recovery System> As shown in FIG. 1, the mud recovery system S is used when a flood occurs due to a typhoon, heavy rain, etc., and when there is flooding under the floor or above the floor in a building B such as a house. More specifically, the mud recovery system S is used to efficiently recover mud M (which may also be muddy water) accumulated in the underfloor space B2 (underfloor space) located beneath the floor B1 of building B. "Flooding above floor level" refers to a situation where the area above the floor of a building (house) is flooded, with the water level exceeding 45 cm from the ground. "Flooding below floor level" refers to a situation where the foundation of the building is flooded, with the water level not exceeding 45 cm from the ground. For example, by law, the height of a building's floor must be at least 45 cm from the ground directly below it to the top of the floor.

[0020] Specifically, as shown in Figures 1 to 3, the mud recovery system S comprises a mud recovery head 1, a first hose 10, a mud recovery container 20, a discharge pump 30, a mud detection sensor 34, and a pump cover 35 installed under the floor B2 of building B; a second hose 40 and a third hose 50 extending from under the floor B2 of building B to the outside; a suction device 60, a mud recovery box 70, and a generator 80 installed outside building B; and an information processing device 100 operated indoors or outdoors of building B. It is equipped with. The discharge pump 30, mud detection sensor 34, and pump cover 35 are located inside the mud collection container 20.

[0021] As shown in Figure 1, the mud collection head 1 is connected to the tip of the first hose 10 and is a hollow head member that sucks up the mud M accumulated under the floor B2 as the suction device 60 operates. Specifically, the mud collection head 1 has a hollow head body 2, a head opening 3 provided at the tip of the head body, and a hose connection part 4 provided at the end of the head body and connected to the first hose.

[0022] The first hose 10, the second hose 40, and the third hose 50 are transfer hoses (transfer pipes) for transporting air and mud M (mud water), as shown in Figures 1 and 2. The first hose 10 is primarily for passing mud M accumulated under the floor B2, and connects the mud collection head 1 and the mud collection container 20. The second hose 40 is primarily used to discharge air from the mud collection container 20 and connects the mud collection container 20 to the suction device 60. The third hose 50 is primarily used to pass the mud M temporarily collected in the mud collection container 20 to the mud collection box 70, and connects the mud collection container 20 (discharge pump 30) and the mud collection box 70. As shown in Figure 1, the first hose 10 extends along the underfloor space B2 of building B. The second hose 40 and the third hose 50 extend from underfloor space B2 through the underfloor opening B3 and out from the inside of building B towards the outside.

[0023] The mud recovery system S (information processing device 100) uses a mud detection sensor 34 to control the suction operation of the suction device 60 and the discharge operation of the discharge pump 30. This control prevents negative pressure from forming inside the mud recovery container 20. In other words, the suction and discharge operations can be performed simultaneously. This eliminates the need to install check valves (non-return valves) on hoses 10, 40, and 50 to prevent backflow of mud M. In other words, check valves can be made unnecessary. However, check valves may be installed on hoses 10, 40, and 50 to more reliably prevent backflow of mud M.

[0024] <<Mud collection container>> As shown in Figures 1 to 3, the mud collection container 20 is a box-shaped container (sealed container) and is sized to be installed under the floor B2 of building B. For example, it is about 30 to 50 cm high so that it fits under the floor B2, and is about 40 to 60 cm long and wide so that it can pass through the underfloor opening B3. The mud collection container 20 can collect mud inside by the suction operation of the suction device 60, which expels air from inside the container body 21 through the second hose 40 and sucks in mud through the first hose 10. In other words, the mud collection container 20 temporarily collects mud inside the container body 21 while maintaining a vacuum (low vacuum) state within the container body 21.

[0025] The mud collection container 20 includes a container body 21 for collecting mud, a lid 22 that covers the container body 21 from above, a first connection part 23 connected to the first hose 10, a second connection part 24 connected to the second hose 40, a third connection part 25 connected to the third hose 50, and a partition plate 26 provided on the upper part of the container body 21. Inside the mud collection container 20 are a discharge pump 30 for discharging the mud collected in the container body 21, a mud detection sensor 34 for detecting when the amount of mud collected in the container body 21 reaches or exceeds a predetermined amount, and a pump cover 35 that covers the discharge pump 30 and the mud detection sensor 34.

[0026] As shown in Figures 2 to 4, the first connection section 23 is a hollow (pipe-shaped) connection section that connects the container body 21 and the first hose 10, and primarily allows mud to pass from the first hose 10 to the container body 21. The first connection section 23 may also be called a connecting section, joint section, or piping. The first connecting portion 23 is fixed through the first side portion 21a of the container body 21, and the portion of the first connecting portion 23 that connects the first hose 10 protrudes horizontally outward from the container body 21.

[0027] The first connecting portion 23 is fixed to the first side portion 21a of the container body 21 and includes a hollow connecting body 23a that protrudes to the outside of the container body 21, and a hollow first connecting nozzle 23b that is connected to the connecting body 23a and extends to the inside of the container body 21. The first connecting nozzle 23b has a first extension portion 23ba that extends from the first side portion 21a toward the center of the container body 21, and a second extension portion 23bb that bends from the extension end of the first extension portion 23ba and extends along the first side portion 21a. The outlet at the extended end of the second extension 23bb becomes the mud discharge outlet 23c.

[0028] As shown in Figures 2, 3, and 5, the second connection part 24 is a hollow (pipe-shaped) joint that connects the container body 21 and the second hose 40, and primarily discharges air from the inside of the container body 21 to the second hose 40. The second connecting portion 24 is fixed by passing through the second side portion 21b of the container body 21, which is located on the opposite side from the first side portion 21a. The portion of the second connection part 24 that connects to the second hose 40 protrudes horizontally outward from the container body 21.

[0029] The second connecting portion 24 is fixed to the second side portion 21b of the container body 21 and includes a hollow connecting body 24a that protrudes to the outside of the container body 21, and a hollow second connecting nozzle 24b that is connected to the connecting body 24a and extends inward into the container body 21. The second connecting nozzle 24b has a first extension portion 24ba extending from the second side portion 21b toward the center of the container body 21, and a second extension portion 24bb bending from the extension end of the first extension portion 24ba and extending along the second side portion 21b. The outlet at the extended end of the second extended portion 24bb becomes the air intake port 24c.

[0030] As shown in Figure 2, the third connection section 25 is a hollow (pipe-shaped) joint that connects the container body 21 and the third hose 50, and primarily discharges mud from the inside of the container body 21 to the third hose 50. The third connecting portion 25 is attached to the lower part of the second side portion 21b of the container body 21 in order to effectively discharge mud accumulated inside the container body 21.

[0031] In the plan view shown in Figure 3, the mud discharge port 23c of the first connection part 23 and the air intake port 24c of the second connection part 24 are located at diagonal positions. More specifically, the mud discharge port 23c and the air intake port 24c face opposite each other in a direction that intersects with the connection direction of the first connection part 23 (second connection part 24). Specifically, the mud discharge port 23c extends toward the third side portion 21c, which connects the first side portion 21a and the second side portion 21b. The air intake port 24c extends toward the fourth side portion 21d, which is located opposite the third side portion 21c. This allows the mud discharge port 23c and the air intake port 24c to be positioned at different locations and orientations within the container body 21, and to be spaced apart from each other. As a result, when the suction device 60 sucks in air from inside the mud collection container 20, it is possible to suppress the inadvertence of sucking in mud along with the air.

[0032] As shown in Figures 3 and 4, the mud discharge port 23c of the first connecting nozzle 23b is oriented diagonally downward inside the container body 21. Furthermore, a first notch 23d is formed at the extended end of the first connecting nozzle 23b, which is continuous with the mud discharge port 23c and positioned to face the first side portion 21a. In other words, the mud discharge port 23c and the opening portion of the first notch 23d serve as outlets for discharging mud. To put it another way, it can be said that the mud discharge port 23c is expanded by the first notch 23d. Furthermore, the opening portion of the mud discharge port 23c faces the third side portion 21c, and the opening portion of the first notch portion 23d faces the first side portion 21a. This allows for efficient discharge of mud into the mud collection container 20 through the first connection section 23 (first connection nozzle 23b). Furthermore, even if mud discharged from the mud discharge port 23c splashes back, measures can be taken to prevent the splashed mud from entering the air intake port 24c.

[0033] As shown in Figures 3 and 5, the air intake port 24c of the second connecting nozzle 24b is oriented laterally inside the container body 21. Furthermore, a second notch 24d is formed at the extended end of the second connecting nozzle 24b, which is continuous with the air intake port 24c and positioned to face the second side portion 21b. In other words, the openings of the air intake port 24c and the second notch 24d serve as entry points for air intake. Furthermore, the opening portion of the air intake port 24c faces the fourth side portion 21d, and the opening portion of the second notch portion 24d faces the second side portion 21b. This allows for efficient suction of air from inside the mud collection container 20 through the second connection part 24 (second connection nozzle 24b).

[0034] In the side view shown in Figure 2, the mud discharge port 23c of the first connection part 23 and the air intake port 24c of the second connection part 24 are positioned diagonally opposite each other. More specifically, the mud discharge port 23c is positioned towards the first side portion 21a of the container body 21 and is located in the lower (slightly lower) portion of the container body 21. The air intake port 24c is positioned towards the second side portion 21b of the container body 21 and is located in the upper portion of the container body 21. Specifically, the mud discharge port 23c is located in the lower part of the corner between the first side portion 21a and the third side portion 21c. The air intake port 24c is located diagonally opposite to the aforementioned corner, in the upper part of the corner between the second side portion 21b and the fourth side portion 21d. This further reduces the likelihood of the suction device 60 accidentally sucking up mud along with the air inside the mud collection container 20.

[0035] As shown in Figure 2, a plate-shaped partition plate 26 is attached to the bottom surface of the lid portion 22 inside the container body 21. The partition plate 26 is positioned between the mud discharge port 23c and the air intake port 24c, and is located at the same height as the first connection part 23 (connecting body 23a) and the second connection part 24 (connecting body 24a). The partition plate 26 is a long plate member in the width direction of the container body 21, extending downward from the lid portion 22. The discharge pump 30 and pump cover 35 are positioned directly below the partition plate 26. By installing the partition plate 26, it is possible to prevent the suction device 60 from directly sucking up the mud discharged into the mud collection container 20. In addition, if mud discharged from the mud discharge port 23c splashes back, the partition plate can be used to prevent the splashed mud from entering the air intake port 24c.

[0036] <<Discharge pump, pump cover>> As shown in Figures 2 and 3, the discharge pump 30 is a small pump installed at the bottom inside the mud collection container 20. The discharge pump 30 operates to discharge the mud collected in the mud collection container 20 into the mud collection box 70 through the third hose 50. The discharge pump 30 includes a pump body 31, a pump suction port 32 for sucking in mud, and a pump discharge port 33 for discharging mud, both of which are provided on the pump body 31. The discharge pump 30 operates (starts operation) under the control of the information processing device 100 and discharges the mud collected in the mud collection container 20. It also stops operating under the control of the information processing device 100. The discharge pump 30 may be started and stopped by manual operation by an operator. For example, an operator may operate the discharge pump 30 based on (and after confirming) the detection result of the mud detection sensor 34.

[0037] As shown in Figures 2 and 3, the mud detection sensor 34 is a mud detection unit that detects when the amount of mud M collected in the mud collection container 20 reaches or exceeds a predetermined amount, and is, for example, a float sensor (also called a float switch or level sensor). Note that the mud detection sensor 34 may be a detector (detection unit) other than a float sensor. The mud detection sensor 34 is connected to the information processing device 100 via communication and detects when the amount of mud M collected reaches a predetermined amount (or exceeds a predetermined amount), and transmits a detection signal to the information processing device 100.

[0038] The mud detection sensor 34 is mounted on the side of the central or lower part of the discharge pump 30 and is positioned above the pump suction port 32. The mud detection sensor 34 may be positioned at the same height as the pump suction port 32 of the discharge pump 30. Alternatively, it may be attached to the inner surface of the pump cover 35. While it is preferable for the mud detection sensor 34 to be positioned inside the pump cover 35 as described later, it is acceptable for it to be positioned inside the mud collection container 20.

[0039] As shown in Figures 2 and 3, the pump cover 35 is a box-shaped cover installed inside the container body 21, surrounding the discharge pump 30 and the mud detection sensor 34. The pump cover 35 has the function of improving the detection accuracy of the mud detection sensor 34 and the function of preventing foreign matter other than mud (such as garbage or large stones) from being sucked into the discharge pump 30. For example, when mud is discharged into the container body 21 from the mud discharge port 23c, waves may be generated on the surface of the mud accumulated inside the container body 21 (the surface of the muddy water), preventing the mud detection sensor 34 from properly detecting the surface of the muddy water. Alternatively, when air is drawn into the container body 21 from the air intake port 24c, waves may also be generated on the surface of the muddy water due to the suction force. Therefore, by covering the mud detection sensor 34 and the discharge pump 30 with the pump cover 35, the surface of the muddy water can be stabilized inside the pump cover 35. It is also possible to suppress the intrusion of foreign matter other than mud.

[0040] The pump cover 35 has a frame-shaped cover body 35a that covers the discharge pump 30 and the mud detection sensor 34 from the side, and a grid-shaped lid portion 35b that is attached to the top of the cover body 35a and covers the discharge pump 30 and the mud detection sensor 34 from above. A mud passage opening 35c is formed on the side of the cover body 35a, allowing mud accumulated in the container body 21 to pass into the inside of the pump cover 35. Furthermore, a pipe passage opening 35d is formed on the side of the cover body 35a for passing the pump piping (pump connection part) of the discharge pump 30.

[0041] The lid portion 35b has a grid-like structure, which allows for adjustment of the air pressure inside the pump cover 35. Furthermore, it prevents foreign matter other than mud from entering through the lid portion 35b. Furthermore, the lid portion 35b is not limited to a lattice-shaped lid, but may also be a lid with air holes formed therein.

[0042] The mud passage opening 35c is formed in the lower part of the cover body 35a and is positioned below the mud detection sensor 34. To prevent foreign matter other than mud from entering through the mud passage opening 35c, it is preferable to attach a grid-like mesh (intrusion suppression member) to the side of the cover body 35a to cover the mud passage opening 35c.

[0043] As described above, by installing the pump cover 35, the detection accuracy of the mud detection sensor 34 can be improved, and the mud accumulated in the mud collection container 20 can be properly discharged into the mud collection box 70.

[0044] <<Suction device, mud collection box, generator>> As shown in Figure 1, the suction device 60, also called a vacuum device, is a device that performs suction operations by receiving electricity from the generator 80. The suction device 60 performs a suction operation to collect the mud M accumulated under the floor B2 into the mud collection container 20 through the mud collection head 1 and the first hose 10. In the suction device 60, the operation is turned on and off manually or by control of the information processing device 100, and the set value of the suction pressure (vacuum pressure) is also controlled.

[0045] As shown in Figure 1, the mud collection box 70 is formed to be larger than the mud collection container 20 and is used to collect the mud M inside, and is a mud collection box such as a drum. The mud collection container 20 temporarily collects the mud M, and the mud collection box 70 collects the mud M after transferring it from the mud collection container 20. The mud collection box 70 has a box body 71, a lid 72, and a third connection part 73 that is connected to the third hose 50. The mud collection box 70 may also have a bag-shaped sandbag for collecting the mud M.

[0046] The generator 80 is a device that generates electricity, for example by electromagnetic induction, and supplies it to the suction device 60. The generator 80 is installed outdoors of building B together with the suction device 60.

[0047] In the above configuration, as shown in Figure 1, the mud collection system S has a small mud collection container 20 installed under the floor B2 of building B. Therefore, the length of the hose can be shortened compared to conventional systems (by using multiple hoses and shortening the length of each hose), and the handling of the hose can be made easier. In other words, it is possible to avoid the hose becoming heavy due to the added weight of mud that occurs when a single hose is long. Furthermore, by providing a mud collection container 20 and a mud collection box 70, the lifting height (suction lift) can be lowered when sucking the mud M accumulated under the floor B2 into the mud collection container 20 (mud collection box 70). Therefore, even when the suction power of the suction device 60 is set low, the mud M can be collected effectively. For example, it becomes possible to use a household suction device (100V specification) instead of a commercial suction device (200V specification).

[0048] The mud recovery system S allows for efficient recovery of mud accumulated under the floor through manual operation by a worker. Furthermore, by controlling the operation of the suction device 60 and discharge pump 30 using the mud detection sensor 34 and information processing device 100, the mud accumulated under the floor can be recovered even more efficiently. A detailed explanation follows below.

[0049] <Control by information processing equipment> As shown in Figures 1 and 6, the information processing device 100 is a computer having a CPU (processor), a storage device (ROM, RAM, HDD), and a communication interface (communication IF), and is communicated with the discharge pump 30, the mud detection sensor 34, and the suction device 60. The information processing device 100 controls the discharge operation of the discharge pump 30 and the suction operation of the suction device 60 based on the detection results from the mud detection sensor 34. The information processing device 100 may be operated by a worker inside building B, or it may be operated outside building B.

[0050] The information processing device 100, in terms of its functionality, mainly consists of a storage unit 101 for temporarily storing various programs and data, a communication unit 102, a decision unit 103, and an operation control unit 104 (control unit). These are composed of a CPU (processor), ROM, RAM, HDD, communication interface, and various programs.

[0051] As shown in Figures 7 and 8, the information processing device 100 (decision unit 103, operation control unit 104) controls the discharge pump 30 and suction device 60 based on the detection results of the mud detection sensor 34. Specifically, it is as follows:

[0052] As shown in Figure 7, the motion control unit 104 first controls the suction device 60 to perform suction. Initially, it is preferable for the motion control unit 104 to operate the suction device 60 after receiving an operation instruction from the operator. Alternatively, the operator may turn on the suction device. The left side of Figure 7 shows that the discharge pump 30 and suction device 60 are stopped (operation OFF). Also, the mud detection sensor 34 is not detecting any mud (detection OFF). In other words, no mud has yet been collected inside the mud collection container 20. The right side of Figure 7 shows the suction device 60 in operation (operation ON state). Also, a small amount of mud has been collected inside the mud collection container 20.

[0053] Then, as shown on the left side of Figure 8, when the determination unit 103 determines, based on the mud detection sensor 34, that a predetermined amount or more of mud has been collected in the mud collection container 20, the operation control unit 104 controls the operation of the discharge pump 30 and the suction device 60. The left side of Figure 8 shows the state in which the discharge pump 30 and suction device 60 are operating (operation ON state). It also shows the state in which the mud detection sensor 34 has detected mud (detection ON state). In other words, a predetermined amount of mud has been collected inside the mud collection container 20.

[0054] Then, as shown on the right side of Figure 8, when the determination unit 103 determines that the mud detection sensor 34 is not detecting mud (detection OFF state), the operation control unit 104 controls the operation of the discharge pump 30 to stop. Figure 8 shows the state in which the discharge pump 30 is not operating (operation OFF state). It also shows that the mud detection sensor 34 is not detecting mud (detection OFF state). In other words, there is almost no mud remaining inside the mud collection container 20. If mud accumulates again in the mud collection container 20 (when the mud detection sensor 34 turns ON), the discharge pump 30 restarts its discharge operation. In addition, although the worker turns off the suction device when the mud collection work is completed, the operation control unit 104 may also perform control to stop the operation of the suction device.

[0055] As shown in Figure 8, the above control allows for the operation of the suction device 60 and the discharge pump 30 to be stopped after detecting that there is almost no mud accumulated in the mud collection container 20. Furthermore, multiple mud detection sensors 34 may be placed at different heights inside the container body 21 to control the operation of the suction device 60 and the discharge pump 30. A more specific control method is shown in the processing flow in Figure 7.

[0056] <Sludge recovery control using information processing equipment (sludge recovery method)> Next, the processing of mud recovery control (mud recovery control program) by the mud recovery system S will be explained based on Figure 9. The above program is executed in response to operational instructions from the operator and will run repeatedly until it receives a stop command from the operator. In the above program, the operation of the suction device 60 is started (operation ON) and stopped (operation OFF) by the operator's instructions. First, the program starts with mud accumulated under the floor and the operation of the suction device 60 started by the operator.

[0057] In the processing flow shown in Figure 9, the process begins with step 1 (S1), in which the information processing device 100 (determination unit 103) determines whether or not the suction device 60 is operating (whether it is turned ON). If it is determined that the suction device 60 is ON (Step 1: Yes), proceed to Step 2. On the other hand, if it is determined that the suction device 60 is not OFF (Step 1: No), proceed to Step 5. At this point, you will naturally proceed to step 2.

[0058] In step 2, the determination unit 103 determines whether a predetermined amount of mud has been collected in the mud collection container 20 by turning the mud detection sensor 34 ON or OFF. If the mud detection sensor 34 is determined to be ON (Step 2: Yes), proceed to Step 3. In step 3, the operation control unit 104 controls the operation of the discharge pump 30 to ON. Then, the process proceeds to the END of the processing flow. (Strictly speaking, it returns to step 1.) This means that a considerable amount of mud has accumulated in the mud collection container 20, the suction device 60 continues its suction operation, and the discharge pump 30 has started its discharge operation.

[0059] On the other hand, if the mud detection sensor 34 is not determined to be ON (Step 2: No), proceed to Step 4. In step 4, the operation control unit 104 controls the operation of the discharge pump 30 to OFF. Then, the process proceeds to the END of the processing flow. (Strictly speaking, it returns to step 1.) This means that it was detected that there was not a significant amount of mud accumulated in the mud collection container 20, and the suction device 60 continued its suction operation, but the discharge pump 30 stopped its discharge operation. If mud accumulates again in the mud collection container 20 when the processing flow is repeated, the process proceeds to step 3, and the discharge pump 30 restarts its discharge operation.

[0060] As the above processing flow is repeated, the mud accumulated under the floor is collected. Once the collection of the mud under the floor is complete, the worker stops the operation of the suction device 60. Starting from this state, the process proceeds to step 5. In step 5, the determination unit 103 determines whether the discharge pump 30 is operating (operation ON). If the discharge pump is determined to be ON in step 5 (Yes), proceed to step 6.

[0061] In step 6, the determination unit 103 determines whether a predetermined amount of mud has been collected in the mud collection container 20 by turning the mud detection sensor 34 ON or OFF. If the mud detection sensor 34 is determined to be ON (Step 6: Yes), proceed to the END of the processing flow. (More precisely, return to Step 1.) This means that mud is still accumulated in the mud collection container 20, the suction device 60 has stopped operating, but the discharge pump 30 continues to discharge.

[0062] If the mud detection sensor 34 is not determined to be ON in step 6 (step 6: No), proceed to step 7. In step 7, the operation control unit 104 controls the discharge pump 30 to turn it OFF. Then, the process proceeds to the END of the process flow. This means that there was almost no mud accumulated in the mud collection container 20, and that the discharge pump 30, in addition to the suction device 60, had stopped working.

[0063] Also, if the discharge pump is determined to be OFF in step 5 (step 5: No), the process proceeds to END. This means that there is almost no mud accumulated in the mud collection container 20, and the suction device 60 and discharge pump 30 have stopped operating.

[0064] With the mud recovery method using the mud recovery system S described above, the suction operation of the suction device 60 and the discharge operation of the discharge pump 30 are performed based on the amount of mud recovered in the mud recovery container 20, allowing for efficient mud recovery.

[0065] <Sludge collection container of the second embodiment> Next, the mud collection container 120 of the second embodiment will be described with reference to Figures 10 and 11. Note that explanations that overlap with those for the mud collection container 20 mentioned above will be omitted.

[0066] The mud collection container 120 comprises a container body 121, a lid 122, a first connection part 123, a second connection part 124, a third connection part 125, a discharge pump 130, and a mud detection sensor 134.

[0067] The first connection section 123 comprises a connection body 123a fixed to the container body 121 (first side section 121a) and a first connection nozzle 123b. The outlet of the extended end of the first connection nozzle 123b becomes the mud discharge port 123c. The second connection section 124 comprises a connection body 124a fixed to the container body 121 (second side section 121b) and a second connection nozzle 124b. The outlet of the extended end of the second connection nozzle 124b becomes the air intake port 124c.

[0068] In the plan view shown in Figure 11, the first connecting portion 123 (first connecting nozzle 123b) is connected to the portion of the first side portion 121a that is positioned towards the third side portion 121c. The second connecting portion 124 (second connecting nozzle 124b) is connected to the portion of the second side portion 121b that is positioned towards the fourth side portion 121d. The mud discharge port 123c and the air intake port 124c face opposite each other in a direction that intersects with the connection direction of the first connection part 123 (second connection part 124).

[0069] As shown in Figure 11, the mud discharge port 123c and the air intake port 124c are positioned diagonally opposite each other in a top view. Specifically, as shown in Figure 11, the mud discharge port 123c of the first connecting nozzle 123b is oriented laterally (directly sideways) inside the container body 121. The air intake port 124c of the second connecting nozzle 124b is oriented diagonally upward inside the container body 121. More specifically, the mud discharge port 123c faces the fourth side portion 121d, and the air intake port faces the third side portion 121c, with the two facing opposite directions.

[0070] In addition, as shown in Figure 10, the first connection part 123 (connection body 123a) and the second connection part 124 (connection body 124a) are positioned at the same height, and the air intake port 124c is positioned above the mud discharge port 123c.

[0071] Even with the above configuration, the suction device can suppress the inadvertent sucking in of mud along with the air inside the mud collection container, allowing for efficient mud collection.

[0072] <Other> In the above embodiment, as shown in Figure 1, the mud collection container 20 is installed under the floor B2 of building B. However, it is not limited to being installed on the floor inside building B. In other words, the mud collection container 20 should be installed in a position closer to under the floor B2 than the mud collection box 70.

[0073] In the above embodiment, as shown in Figure 1, the mud recovery system S is equipped with an information processing device 100, but it is not particularly limited and does not need to be equipped with an information processing device 100. That is, the operator may manually operate the discharge operation of the discharge pump 30 and the suction operation of the suction device 60.

[0074] In the above embodiment, as shown in Figure 1, the mud recovery system S includes a discharge pump 30, a mud detection sensor 34, and a pump cover 35, but it is not particularly limited and does not necessarily have to include these components. For example, if the mud collection system S does not have a discharge pump 30, the worker may replace the mud collection container 20 as needed.

[0075] In the above embodiment, as shown in Figure 2, the first connecting portion 23 and the second connecting portion 24 are connected to the first side portion 21a and the second side portion 21b of the container body 21 along the longitudinal direction of the container body 21, but this is not particularly limited. For example, the first connecting portion 23 and the second connecting portion 24 may be connected along the width direction of the container body 21. Alternatively, the first connecting portion 23 may be connected to the first side portion 21a along the length direction of the container body 21, and the second connecting portion 24 may be connected to the third side portion 21c along the width direction of the container body 21. Alternatively, the first connecting portion 23 may be connected to the third side portion 21c, and the second connecting portion 24 may be connected to the first side portion 21a of the container body 21.

[0076] In the above embodiment, as shown in Figures 2 and 3, the first connecting portion 23 is attached to the first side portion 21a of the container body 21 and the second connecting portion 24 is attached to the second side portion 21b, but this is not particularly limited. For example, the first connecting portion 23 may be attached to the first side portion 21a, and the second connecting portion 24 may be attached to the third side portion 21c (the side portion connecting the first side portion 21a and the second side portion 21b). In this case, it is preferable that the mud discharge port 23c at the extended end of the first connecting portion 23 and the air intake port 24c at the extended end of the second connecting portion 24 are positioned diagonally opposite each other in a top view or side view of the mud collection container 20.

[0077] In the above embodiments, the mud recovery container and mud recovery system according to the present invention were mainly described. However, the embodiments described above are merely examples to facilitate understanding of the present invention and do not limit it. The present invention can be modified and improved without departing from its spirit, and of course, equivalents thereof are included. In particular, the embodiments described above are merely examples and do not limit the present invention. [Explanation of Symbols]
