Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the drainage pump described in Patent Document 1, in a situation where it is temporarily necessary to be lifted manually, such as loading and unloading from the loading platform of a drainage pump vehicle or climbing a steep slope to transport the drainage pump to the disaster site, it is difficult to effectively apply force manually to lift it, resulting in poor workability. That is, there is a problem with flexible portability according to the situation at the disaster site.

[0006] In addition, when arriving at the disaster site and actually performing drainage work at the flooded area, it is necessary to throw the drainage pump into the flooded area. Considering the weight of the drainage pump (generally 40 kg or more), the drainage pump needs to be lifted by multiple people and thrown into the flooded area.

[0007] This invention has been made in view of the above problems, and aims to provide a drainage pump that can be effectively lifted and transported by multiple people, that is, a pump that improves portability for the user. [Means for solving the problem]

[0008] To achieve the above objective, the drainage pump according to the first invention is: A pump for drainage pump trucks used in drainage pump trucks, A casing and a gripping portion provided on the casing, which is used to grip the pump for the drainage pump truck during transport. each It has multiple handles, An annular float with an opening formed therein Equipped with, The float is connected to the casing via a string-like body, and each of the multiple gripping portions of the multiple handles is provided in the casing at intervals that fit inside the opening. It is.

[0009] According to this, when transporting a drainage pump, multiple users can lift and transport the pump by gripping separate gripping points on either side of the pump. In this case, the users can efficiently share and bear the weight of the drainage pump.

[0010] In particular, when lifting the drainage pump and moving it up or down a slope, the users on both sides of the pump can be positioned in a single line in relation to the direction of travel and in a direction intersecting the pump's axis C, allowing them to transport the pump in this manner. Therefore, on a slope, the users on both sides can lift and transport the drainage pump at approximately the same height. Consequently, the drainage pump can be effectively lifted and transported by multiple people applying force, improving its portability for users.

[0011] Furthermore, even when connected to a float, the drainage pump can be carried by multiple users gripping the handle, eliminating the need to hold the float when it is deployed into a flooded area. Therefore, excessive force is not applied to the connection between the float and the string-like body, preventing premature damage to the connection between the drainage pump and the float.

[0012] The drainage pump according to this second invention is A pump for drainage pump trucks used in drainage pump trucks, A casing, and a handle provided on the casing, having multiple gripping parts for gripping when transporting the pump for the drainage pump truck, An annular float with an opening formed therein Equipped with, The float is connected to the casing via a string-like body, and each of the multiple gripping portions is provided in the casing at intervals that fit inside the opening. It is.

[0013] According to this, the drainage pump offers cost advantages because it simplifies the pump's configuration by reducing the number of handle parts while improving portability for the user.

[0014] The drainage pump according to this third invention is multiple of The aforementioned Gripping part Each of at least one pair of the gripping portions The axial direction of the casing and intersect It extends in that direction.

[0015] According to this, when a user throws a drainage pump into a flooded area, the direction in which the drainage pump is inserted is aligned with the axial direction of the casing. Crossing This ensures that the pump moves in the direction of the casing's axis. Therefore, even if the initial force of the pump is weak, it is possible to prevent the drainage pump from contacting the ground (such as a quay). Also, the direction of transport when the drainage pump is transported is in the direction of the casing's axis. Crossing This is the direction in which the pump will be lifted. Therefore, on a slope, users on both sides can lift and transport the drainage pump at approximately the same height, preventing the drainage pump from coming into contact with the slope.

[0018] This 4 The handle of the drain pump according to the invention has a connecting portion that connects the gripping portion to the casing, the pair of gripping portions are provided on the upper part of the casing via the connecting portion, and the connecting portion is provided at both ends of each of the pair of gripping portions and is connected to the casing.

[0019] According to this, because the gripping part is fixed to the casing via the connecting part, the drainage pump can be transported more stably by the user, even when transporting it on steep slopes, for example.

[0020] This 5 The handle of the drain pump according to the invention has a connecting portion that connects the gripping portion to the casing, and the connecting portion is a string-like body.

[0021] According to this, even when there are space restrictions on the loading platform of the drainage pump truck, the drainage pump can be accommodated with a reduced dedicated space by loosening the string-like body and allowing the gripping portion to hang along the casing.

Advantages of the Invention

[0022] According to the present invention, during the transportation of the drainage pump, a plurality of users can lift and transport the pump by gripping separate gripping portions from both the left and right sides where the drainage pump is sandwiched. At this time, the users can efficiently share and bear the mass of the drainage pump. Therefore, the drainage pump can be effectively lifted and transported by a plurality of people, that is, the portability by the users can be improved.

[0024] <First Embodiment> Hereinafter, a drain pump 100 according to the first embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts will be denoted by the same reference numerals to avoid repetition in the description. In the following description, terms such as "up," "down," "side," and "vertical" may be used to mean position or direction. These terms are used for convenience to facilitate understanding of the embodiment and are not limited to the position or direction in actual implementation.

[0025] [Drainage pump truck] First, the drainage pump truck 1 according to the present invention will be described with reference to Figure 1. Figure 1 is a schematic diagram showing the drainage pump truck 1 according to the present invention.

[0026] As shown in Figure 1, the drainage pump truck 1 comprises a drainage pump 100, a generator 3 for generating electricity to drive the drainage pump 100, an operation control panel 4 for operating the generator 3 and the drainage pump 100, a power cable 5 for supplying power from the generator 3 to the drainage pump 100, and a drainage hose 6 for transporting the water discharged by the drainage pump 100 to a nearby river or the like for drainage.

[0027] Drainage pump truck 1 is dispatched to disaster sites when water-related disasters such as floods and inundation of underpasses occur due to typhoons, localized heavy rains, etc. Drainage pump truck 1 is equipped with a generator 3, drainage hoses 6, and other components, including a drainage pump 100, on a single vehicle to enable mobile and efficient drainage work. At the flooded area, the drainage pump 100 is activated and drains the water from the flooded area through the drainage hoses 6 to nearby rivers, etc.

[0028] [Drainage pump] Next, with reference to Figure 2, a drainage pump 100 according to the first embodiment of the present invention will be described. Figure 2 is a perspective view showing the drainage pump 100 according to the first embodiment of the present invention.

[0029] As shown in Figure 2, the drain pump 100 comprises a casing 10, a plurality of handles 20 provided on the casing 10, and a connector 30 for connecting to a power cable 5. Although not shown, the drain pump 100 also includes a motor that is powered and driven internally, a screw that is rotationally driven by the motor, and a plurality of bearings that rotatably support the rotation shafts of the motor and the screw.

[0030] The casing 10 has a suction port 11 for drawing in water using the suction pressure generated by the rotation of the screw, a discharge port 12 for discharging the drawn-in water, a support portion 14 for supporting the handle 20, and legs 16 for stably placing the drain pump 100 on a flat surface. Both the suction port 11 and the discharge port 12 are located on the axis of the casing 10 (hereinafter referred to as the pump axis C). The axis of rotation of the screw is the same as the pump axis C.

[0031] The multiple handles 20 are specifically a first handle 21 and a second handle 26. The first handle 21 and the second handle 26 each have gripping portions 22 and 27 and connecting portions 23 and 28, respectively.

[0032] Each gripping portion 22, 27 is provided to extend in a direction perpendicular to the pump axis C. Each gripping portion 22, 27 is provided on the upper part of the casing 10 via connecting portions 23, 28. In other words, each gripping portion 22, 27 is provided so that its longitudinal direction in a top view is perpendicular to the pump axis C. Each gripping portion 22, 27 is gripped by the user when transporting the drain pump 100.

[0033] Furthermore, each gripping portion 22, 27 is provided in parallel on the casing 10. In this case, it is preferable that each gripping portion 22, 27 is provided so that its height is equal. Moreover, it is preferable that the intersection point of each gripping portion 22, 27 and the pump axis C in a top view is located approximately midway between the pump's center of gravity G (not shown).

[0034] The connecting parts 23 and 28 connect the gripping parts 22 and 27 to the support part 14 of the casing 10. Specifically, the connecting parts 23 and 28 have one end 23a and 28a provided at both ends of the respective gripping parts 22 and 27, while the other end 23b and 28b are connected to the support part 14 of the casing 10.

[0035] In this embodiment, the gripping portions 22 and 27 are arranged in pairs on the casing 10, but it is also possible to configure the device so that three or more gripping portions are arranged on the casing 10. In that case, at least one pair of the multiple gripping portions extends in a direction perpendicular to the pump axis C and is arranged in parallel.

[0036] With the above configuration, as shown in Figure 3, when transporting the drain pump 100, multiple users U1 and U2 can grasp the separate gripping parts 22 and 27 from both the left and right sides of the drain pump 100, lift the drain pump 100, and transport it while maintaining a comfortable carrying position. At this time, the multiple users U1 and U2 can efficiently share and bear the mass of the drain pump 100.

[0037] In particular, when lifting the drainage pump 100 and moving it up or down a slope, users U1 and U2 on either side of the drainage pump 100 can transport it in a line horizontally relative to the direction of travel and perpendicular to the direction of the pump axis C. Therefore, on a slope, users U1 and U2 on the left and right can lift and transport the drainage pump 100 at almost the same height, preventing the drainage pump 100 from coming into contact with the ground.

[0038] Furthermore, since the gripping parts 22 and 27 are connected and fixed to the casing 10 by the connecting parts 23 and 28, users U1 and U2 can stably transport the drainage pump 100 even on a slope by gripping the gripping parts 22 and 27.

[0039] In contrast, in the case of a drainage pump in which the pair of gripping parts do not have the above configuration, for example, a drainage pump in which the pair of gripping parts extend along the pump axis C direction and are arranged in series, multiple users will transport the drainage pump in a line along its longitudinal direction. In this case, especially when lifting the drainage pump and going up or down a slope, if the users are lined up in a line in the direction of travel, the users in front and behind will be at different heights on the slope, making it difficult to efficiently share the weight of the drainage pump.

[0040] In this case, from the state shown in Figure 3, when users U1 and U2 throw the drainage pump 100 into the flooded area in front of them, they lift the drainage pump 100 and swing it like a pendulum back and forth, using their shoulders as a pivot point, to gain momentum before throwing it in.

[0041] In this case, the drainage pump 100 is introduced into the flooded area with its axis C facing left and right, rather than in front of or behind the users U1 and U2. As a result, the direction in which the drainage pump 100 is introduced is perpendicular to the axis C, and even if the force of introduction is weak, it is possible to prevent the suction port 11 or discharge port 12 of the drainage pump 100 from coming into contact with the ground (such as a quay).

[0042] As described above, the drainage pump 100 can be effectively lifted and transported by multiple people applying force, thus improving its portability for users.

[0043] Of course, the direction in which each gripping portion 22, 27 extends may not be strictly perpendicular to the pump axis C direction due to manufacturing variations, assembly variations, etc., and may intersect the pump axis C direction at an angle other than 90°.

[0044] The gripping portions 22 and 27 may be configured to be provided on the side surface of the casing 10, as shown in Figure 4. Figure 4 is a perspective view showing a drainage pump 200 according to the first modified example of this embodiment.

[0045] As a result, when transporting the drainage pump 200 on the bed of the drainage pump truck 1, even if there are constraints on the vertical storage space on the bed, the gripping parts 222 and 227 are provided on the sides of the casing 10, so that they are not subject to vertical constraints on the bed, and the user can place the drainage pump 200 on the bed of the drainage pump truck 1.

[0046] Furthermore, as shown in Figure 5, each gripping portion 322, 327 may be configured to be fixed to the casing 10 by a single connecting portion 323, 328. Figure 5 is a perspective view showing a drainage pump 300 according to a second modified example of this embodiment.

[0047] This allows the drain pump 300 to reduce the number of parts that make up the handle 320, thus providing cost benefits.

[0048] <Second Embodiment> Next, with reference to Figure 6, a drainage pump 400 according to a second embodiment of the present invention will be described. Figure 6 is a perspective view showing a drainage pump 400 according to a second embodiment of the present invention.

[0049] As shown in Figure 6, the drain pump 400 has a handle 420 provided on the casing 10. The handle 420 has a plurality of gripping parts 422, 427 and connecting parts 424, 425.

[0050] The multiple gripping portions 422, 427 are specifically the first gripping portion 422 and the second gripping portion 427. The connecting portions 424, 425 are specifically the first connecting portion 424 extending along the pump axis C direction and the second connecting portion 425 connecting the first connecting portion 424 to the upper part of the casing 10. The first gripping portion 422 and the second gripping portion 427 are connected to the first connecting portion 424 near their respective longitudinal centers 422a, 427a. The second connecting portion 425 is interposed between the lower part of the first connecting portion 424 and the upper part of the casing 10, connecting them to each other.

[0051] In other words, in this embodiment, the handle 420 is configured as a single unit by connecting the multiple gripping parts 422 and 427 with the connecting parts 424 and 425.

[0052] Similar to the first embodiment, each gripping portion 422, 427 is provided to extend in a direction perpendicular to the pump axis C. Furthermore, each gripping portion 422, 427 is provided in parallel with the casing 10.

[0053] As a result, similar to the first embodiment, when transporting the drainage pump 400, multiple users can efficiently share the mass of the drainage pump 400 by gripping the separate gripping parts 422 and 427 from both the left and right sides of the pump, thereby lifting the pump. Therefore, the drainage pump 400 can be effectively lifted and transported by multiple people applying force. In other words, the portability of the drainage pump 400 by users can be improved.

[0054] Furthermore, in this embodiment, the number of parts in the handle 420 can be reduced compared to the first embodiment, and the configuration can be simplified. Therefore, the drain pump 400 can obtain cost advantages compared to the first embodiment.

[0055] The first connecting portion 424 may be connected to the first gripping portion 422 and the second gripping portion 427 at any point. For example, as shown in Figure 7, the first connecting portion 524 may be configured to be connected to one end 522a, 527a of the respective gripping portions 522, 527. Figure 7 is a perspective view showing a modified example of this embodiment of a drain pump 500. The second connecting portion 525 may also be composed of multiple portions, as shown in Figure 7, each connecting both ends of the first connecting portion 524 to the casing 10.

[0056] Furthermore, although not shown, the first connecting portion 524 may also be configured to connect to the other ends 522b and 527b of the gripping portions 522 and 527, in addition to the modified example shown in Figure 7. That is, the first connecting portion 524 is connected to both ends of the first gripping portion 522 and the second gripping portion 527, respectively, to form a square-shaped handle.

[0057] <Third Embodiment> Next, with reference to Figure 8, a drainage pump 600 according to a third embodiment of the present invention will be described. Figure 8 is a perspective view showing a drainage pump 600 according to a third embodiment of the present invention.

[0058] As shown in Figure 8, the drain pump 600, like the drain pump 100 according to the first embodiment, is equipped with a plurality of handles 620 arranged in parallel on the casing 10. Specifically, the plurality of handles 620 are a first handle 621 and a second handle 626. The first handle 621 and the second handle 626 each have gripping portions 622, 627 and connecting portions 623, 628, respectively.

[0059] Each gripping portion 622, 627 is provided to extend in a direction parallel to the pump axis C. In this case, it is preferable that each gripping portion 622, 627 is provided to be symmetrical with respect to the pump axis C when viewed from above.

[0060] As a result, similar to the first embodiment, as shown in Figure 9, when transporting the drain pump 600, multiple users U1, U2 of the drain pump 600 can each grasp the separate gripping parts 622, 627 on either side of the drain pump 600 and lift and transport the pump.

[0061] Therefore, the drainage pump 600 can be efficiently transported by multiple people sharing the weight of the pump. In other words, the portability of the drainage pump 600 can be improved by the user.

[0062] In detail, compared to the first embodiment (refer to Figures 3 and 9 for comparison), in the drainage pump 600 according to this embodiment, the distance between users U1 and U2 is shorter compared to the case of the drainage pump 100 according to the first embodiment. Therefore, users U1 and U2 can share the mass of the drainage pump 600 and transport it more efficiently than when transporting the drainage pump 100 according to the first embodiment.

[0063] On the other hand, since the pump axis C (not shown) is in the front-to-back direction of users U1 and U2, compared to the drainage pump 100 according to the first embodiment, when users U1 and U2 put the drainage pump 600 into the flooded area in front of them, the direction in which the drainage pump 600 is put in is in line with the pump axis C. As a result, when users U1 and U2 lift the drainage pump 600 and swing it like a pendulum in the front-to-back direction with their shoulders as the pivot point to throw the drainage pump 600 into the flooded area, if the momentum at the time of putting it in is weak, there is a higher possibility that the suction port 11 or discharge port 12 of the drainage pump 600 will come into contact with the ground (such as a quay).

[0064] In other words, the drainage pump 600 according to this embodiment has advantages and disadvantages compared to the drainage pump 100 according to the first embodiment, so it is desirable for users to consider the appropriate embodiment depending on the situation at the disaster site.

[0065] Furthermore, the direction in which each gripping portion 622, 627 extends may be configured not to be strictly parallel to the pump axis C direction due to manufacturing variations of the handle 620 or variations in the assembly of the handle 620 to the casing 10.

[0066] <Fourth Embodiment> Next, with reference to Figure 10, a drainage pump 700 according to a fourth embodiment of the present invention will be described. Figure 10 is a perspective view showing a drainage pump 700 according to a fourth embodiment of the present invention.

[0067] As shown in Figure 10, the drain pump 700 further comprises the drain pump 100 according to the first embodiment, with an annular float 40 having an opening that opens in the vertical direction. The drain pump 700 has a plurality of gripping parts 22, 27 provided in the casing 10 at intervals that fit inside the opening.

[0068] The drainage pump 700 has a chain-like member 41 as a string-like body that connects the float 40 and the casing 10. The string-like body may be made of wire, rope, or the like. The chain-like member 41 is connected to the float 40 by a connecting member 42. As shown in Figure 11, when used underwater, the float 40 suspends and supports the casing 10. Figure 11 is a perspective view showing the drainage pump 700 in use underwater.

[0069] In most cases when using the drainage pump 700 in a flooded area, the drainage pump 100 is used while suspended by a float 40. In this case, the float 40 floats on the surface of the water in the flooded area, and the drainage pump 100 is suspended from the float 40 into the water. If the drainage pump 700 is used without the float 40, the drainage pump 700 will sink to the bottom of the flooded area, and as a result of sucking in sediment and other debris from the bottom through the suction port 11, it may cause malfunctions or other problems.

[0070] Conventionally, when a drainage pump connected to a float 40 was lowered into a flooded area, the float 40, with the drainage pump 100 suspended from it, was lowered into the water. However, because the drainage pump 100 is heavy, the entire weight of the drainage pump 100 is placed on the connecting member 42 between the chain-like member 41 that suspends the drainage pump 100 and the float 40. As a result, there was a problem that the connection between the connecting member 42 and the float 40 would break prematurely.

[0071] In contrast, the drain pump 700 can be mounted on top of the float 40 with the multiple gripping parts 22, 27 housed inside the opening of the float 40. At this time, the multiple gripping parts 22, 27 of the drain pump 700 can be gripped from above by users U1, U2 through the opening, as shown in Figure 12. Figure 12 is a front view and a partial cross-sectional view showing the transport state of the drain pump 700.

[0072] Therefore, even when the casing 10 and the float 40 are connected, the drain pump 700 can be transported by multiple users U1, U2 by gripping the gripping parts 22, 27, similar to the drain pump 100 according to the first embodiment. Thus, the drain pump 700, like the drain pump 100, can be made more portable by users U1, U2.

[0073] As shown in Figure 12, users U1 and U2 can lower the drain pump 100 together with the float 40 into the flooded area while gripping the gripping parts 22 and 27. Therefore, when the drain pump 700 is lowered into the flooded area, it is not necessary to hold the float 40. Consequently, excessive force is not applied to the connecting member 42 between the float 40 and the chain-like member 41, and the drain pump 700 can prevent premature damage at the connection point between the connecting member 42 and the float 40.

[0074] Furthermore, the drainage pumps 300, 400, 500, and 600 according to the second and third embodiments described above may be configured to include a float 40.

[0075] <Fifth Embodiment> Next, with reference to Figure 13, a drainage pump 800 according to a fifth embodiment of the present invention will be described. Figure 13 is a perspective view showing a drainage pump 800 according to a fifth embodiment of the present invention.

[0076] As shown in Figure 13, the drain pump 800 has connecting parts 823 and 828 that connect the gripping parts 822 and 827 to the upper part of the casing 10. The connecting parts 823 and 828 are string-like bodies, specifically chain-like members.

[0077] Because the connecting parts 823 and 828 are chain-like members, the drain pump 800 can maintain sufficient strength when transporting the drain pump 800, connecting the gripping parts 822 and 827 to the casing 10.

[0078] On the other hand, when the drainage pump 800 is housed on the bed of the drainage pump truck 1, the connecting parts 823 and 828 of the drainage pump 800 are chain-like members, allowing the chain-like members to be slackened and the gripping parts 822 and 827 to hang down along the casing 10. Therefore, even if there are space constraints on the bed of the drainage pump truck 1, the drainage pump 800 can be housed in a way that reduces the space it occupies by allowing the gripping parts 822 and 827 to hang down along the casing 10.

[0079] Embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from the spirit of the invention. The drawings schematically show each component in order to facilitate understanding, and the thickness, length, number, spacing, etc. of each component shown may differ from the actual dimensions due to the convenience of drawing creation. Furthermore, the material, shape, dimensions, etc. of each component shown in the above embodiments are examples and are not particularly limited, and various modifications are possible without substantially departing from the configuration of the present invention.
