Description

[Technical field]

[0001] The present invention relates to a pump for a drainage pump vehicle. [Background technology]

[0002] Pumps for drainage pump vehicles (hereinafter referred to simply as "drainage pumps") mounted on drainage pump vehicles, etc. are used in emergencies such as disasters, so it is desirable for them to be configured so that they can be transported by human power to enable flexible and rapid response.

[0003] The drainage pump described in Patent Document 1 has a dolly connected to the bottom of the drainage pump, and the drainage pump can be transported by manually pushing the dolly. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2009-197669 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the drainage pump described in Patent Document 1 has poor workability because it is difficult to effectively lift it manually in situations where it is necessary to temporarily lift it by hand, such as when it is necessary to load and unload it from the bed of a drainage pump truck or transport the drainage pump up a steep slope to reach the disaster site. In other words, there was an issue with flexible portability according to the situation at the disaster site.

[0006] In addition, when arriving at the disaster site and actually carrying out drainage work in the flooded areas, it is necessary to throw a drainage pump into the flooded area, and considering the weight of a drainage pump (generally over 40 kg), the drainage pump needs to be lifted by multiple people and dropped into the flooded area.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a drainage pump that can be effectively lifted and carried by multiple people by applying force, i.e., improves portability for users. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the drainage pump according to the first invention comprises a casing and a plurality of handles provided on the casing and having gripping portions which are gripped when transporting the drainage pump, and at least one pair of the plurality of gripping portions extend in a direction intersecting the axial direction of the casing and are arranged in parallel.

[0009] According to this, when transporting the drainage pump, multiple users can lift and transport the pump by gripping different gripping parts on both sides of the drainage pump. At this time, the users can efficiently share and bear the weight of the drainage pump.

[0010] In particular, when lifting the drainage pump to go up or down a slope, the users on either side of the drainage pump can carry the pump in a state where they are in a horizontal line in the direction of travel and in a direction that intersects with the direction of the pump axis C. This allows the users on the left and right sides of the slope to lift and carry the drainage pump at approximately the same height. Therefore, the drainage pump can be lifted and carried by multiple people effectively applying force, improving portability for users.

[0011] In contrast, in the case of a drainage pump in which the pair of gripping parts is not configured as described above, for example, in the case of a drainage pump in which the pair of gripping parts extend along the axial direction of the casing and are arranged in series, multiple users will carry the drainage pump while lining up vertically in the longitudinal direction of the drainage pump. In this case, particularly when lifting the drainage pump and going up and down a slope, if users are lined up vertically in the direction of travel, the front and rear users will be at different heights on the slope, making it difficult to efficiently share the weight of the drainage pump.

[0012] The drainage pump according to the second invention comprises a casing and a handle provided on the casing and having a plurality of gripping portions which are gripped when transporting the drainage pump, and at least one pair of the plurality of gripping portions extend in a direction intersecting the axial direction of the casing and are arranged in parallel.

[0013] This provides a cost advantage since the drainage pump can be simplified in structure by reducing the number of parts in the handle while improving portability for the user.

[0014] In the drainage pump according to the third aspect of the present invention, the pair of grip portions extend in a direction perpendicular to the axial direction of the casing and are provided in parallel.

[0015] With this, when a user throws the drainage pump into a flooded area, the direction in which the drainage pump is thrown is perpendicular to the axial direction of the casing. Therefore, even if the force of throwing the drainage pump is weak, the drainage pump can be prevented from contacting the ground (such as a seawall). In addition, the direction in which the drainage pump is transported is perpendicular to the axial direction of the casing. Therefore, users on both sides of a slope can lift and transport the drainage pump at approximately the same height, preventing the drainage pump from contacting the slope.

[0016] The drainage pump according to the fourth invention further comprises an annular float having an opening formed therein, the float being connected to the casing via a string-like body, and the multiple gripping portions being provided on the casing at intervals that fit within the inside of the opening.

[0017] According to this, even when connected to the float, the drainage pump can be transported by multiple users by holding the handle, so there is no need to hold the float when placing it in a flooded area. Therefore, since excessive force is not applied to the connection part between the float and the string-like body, the drainage pump can prevent early damage to the connection part with the float.

[0018] The handle of the drainage pump according to the fifth invention has a connecting portion that connects the grip portion to the casing, and the pair of grip portions are provided on the upper part of the casing via the connecting portions, and the connecting portions are provided on both ends of each of the pair of grip portions and connected to the casing.

[0019] With this, since the grip portion is fixed to the casing via the connecting portion, the drainage pump can be transported stably by the user even when being transported, for example, on a steep slope.

[0020] The handle of the drainage pump according to the sixth aspect of the present invention has a connecting portion that connects the grip portion to the casing, and the connecting portion is a string-like body.

[0021] As a result, even if there are space constraints on the bed of the drainage pump truck, the drainage pump can be stored in a small space by slackening the string-like body and letting the handle hang down along the casing. Effect of the Invention

[0022] According to the present invention, when transporting the drainage pump, multiple users can lift and transport the pump by gripping separate gripping parts on both the left and right sides of the drainage pump. At this time, the users can efficiently share and bear the weight of the drainage pump. Therefore, the drainage pump can be lifted and transported by multiple people effectively applying force, which improves portability for users. [Brief description of the drawings]

[0024] First embodiment Hereinafter, a drainage pump 100 according to a first embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference symbols and will not be described repeatedly. In the following description, terms that indicate positions or directions, such as "upper", "lower", "horizontal" and "vertical", may be used. These terms are used for convenience to facilitate understanding of the embodiment, and are not limited to positions or directions when actually implemented.

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

[0026] As shown in FIG. 1, the drainage pump vehicle 1 includes a drainage pump 100, a generator 3 that generates 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 that supplies power from the generator 3 to the drainage pump 100, and a drainage hose 6 that transports the water discharged by the drainage pump 100 to a nearby river or the like for drainage.

[0027] The drainage pump vehicle 1 is dispatched to the disaster site when a water disaster such as flooding or submersion of an underpass occurs due to a typhoon, localized heavy rain, etc. The drainage pump vehicle 1 is equipped with a drainage pump 100, a generator 3, a drainage hose 6, etc. in one vehicle so that it can perform drainage work swiftly and efficiently. The drainage pump 100 is deployed in the flooded area, and the drainage pump 100 drains water from the flooded area through the drainage hose 6 into a nearby river or the like.

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

[0029] 2, the drainage pump 100 includes a casing 10, a number of handles 20 provided on the casing 10, and a connector 30 that connects to a power cable 5. Although not shown, the drainage pump 100 includes a motor that is driven by power supplied thereto, a screw that is rotationally driven by the motor, and a number of bearings that rotatably support the rotating shafts of the motor and the screw.

[0030] The casing 10 has a suction port 11 that draws in water by the suction pressure generated by the rotation of the screw, a discharge port 12 that expels the drawn in water, a support 14 that supports a handle 20, and legs 16 for stably placing the drainage pump 100 on a flat surface. The suction port 11 and the discharge port 12 are both located on the axis of the casing 10 (hereinafter referred to as the pump axis C). The axis of the rotation shaft 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 have gripping portions 22, 27 and connecting portions 23, 28, respectively.

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

[0033] The gripping portions 22, 27 are provided in parallel on the casing 10. In this case, it is preferable that the gripping portions 22, 27 are provided so that the heights of the gripping portions 22, 27 are equal. Furthermore, it is preferable that the gripping portions 22, 27 are provided at positions such that the intersections between the gripping portions 22, 27 and the pump axis C in a top view are located near the midpoints thereof, sandwiching the center of gravity G (not shown) of the pump.

[0034] The connecting portions 23, 28 connect the gripping portions 22, 27 to the support portion 14 of the casing 10. Specifically, the connecting portions 23, 28 have one end sides 23a, 28a provided on both ends of the respective gripping portions 22, 27, and the other end sides 23b, 28b connected to the support portion 14 of the casing 10.

[0035] In this embodiment, the gripping portions 22, 27 are arranged as a pair on the casing 10, but three or more gripping portions may be arranged on the casing 10. In this case, at least a pair of the gripping portions among the multiple gripping portions extend in a direction perpendicular to the direction of the pump axis C and are arranged in parallel.

[0036] 3, when transporting the drainage pump 100, multiple users U1, U2 can grasp the separate gripping parts 22, 27 from both the left and right sides of the drainage pump 100, lift the drainage pump 100, and transport it while maintaining a posture that is easy to hold. At this time, the multiple users U1, U2 can efficiently share and bear the weight of the drainage pump 100.

[0037] In particular, when lifting the drainage pump 100 and moving it up and down a slope, the users U1 and U2 on either side of the drainage pump 100 can transport the drainage pump 100 in a state where they are aligned horizontally in the direction of travel and in a direction perpendicular to the direction of the pump axis C. Therefore, the users U1 and U2 on the left and right sides of the slope can lift and transport the drainage pump 100 at approximately the same height, preventing the drainage pump 100 from contacting the ground.

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

[0039] In contrast, in the case of a drainage pump in which the pair of gripping parts are not configured as described above, for example, in the case of a drainage pump in which the pair of gripping parts extend along the direction of the pump axis C and are arranged in series (not shown), multiple users will transport the drainage pump while lining up vertically in the longitudinal direction of the drainage pump. In this case, particularly when lifting the drainage pump and going up and down a slope, if users are lined up vertically in the direction of travel, the front and rear users will be at different heights on the slope, making it difficult to efficiently share the weight of the drainage pump.

[0040] Now, when users U1 and U2 throw the drainage pump 100 into the flooded area in front from the state shown in Figure 3, users U1 and U2 lift the drainage pump 100 and swing it back and forth like a pendulum, using their shoulders as a fulcrum, to gain momentum and throw it in.

[0041] At this time, the drainage pump 100 is inserted into the flooded area with the pump axis C facing left and right, not front and rear, of the users U1 and U2. Therefore, the insertion direction of the drainage pump 100 is perpendicular to the pump axis C, and even if the force at the time of insertion is weak, the suction port 11 or discharge port 12 of the drainage pump 100 can be prevented from contacting the ground (such as a quay).

[0042] As described above, the drainage pump 100 can be lifted and carried effectively by multiple people using their strength, which improves portability for users.

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

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

[0045] As a result, when the drainage pump 200 is placed on the loading platform of the drainage pump vehicle 1 for transportation, even if there are restrictions on the vertical storage space of the loading platform, since each of the gripping parts 222, 227 is provided on the side of the casing 10, there is no vertical restriction on the loading platform, and the user can place the drainage pump 200 on the loading platform of the drainage pump vehicle 1.

[0046] Furthermore, as shown in Fig. 5, each of the gripping portions 322, 327 may be configured to be fixed to the casing 10 by a single connecting portion 323, 328. Fig. 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, thereby achieving cost benefits.

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

[0049] 6, the drainage pump 400 has a handle 420 provided on the casing 10. The handle 420 has a plurality of gripping portions 422, 427 and connecting portions 424, 425.

[0050] The multiple gripping portions 422, 427 are specifically a first gripping portion 422 and a second gripping portion 427. The connecting portions 424, 425 are specifically a first connecting portion 424 extending along the direction of the pump axis C and a second connecting portion 425 connecting the first connecting portion 424 to an upper portion 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 portion of the first connecting portion 424 and the upper portion of the casing 10 to connect them to each other.

[0051] That is, in this embodiment, the handle 420 is configured as a single piece by connecting the multiple gripping portions 422, 427 with the connecting portions 424, 425.

[0052] Similarly to the first embodiment, the gripping portions 422, 427 are provided so as to extend in a direction perpendicular to the direction of the pump axis C. Furthermore, the gripping portions 422, 427 are provided in parallel on the casing 10.

[0053] As a result, similarly to the first embodiment, when transporting the drainage pump 400, multiple users can grip the separate gripping portions 422, 427 from both the left and right sides of the drainage pump 400, and lift the pump while efficiently sharing the mass of the drainage pump 400. Therefore, the drainage pump 400 can be lifted and transported by multiple people effectively applying force. In other words, the drainage pump 400 can be made more portable for users.

[0054] Furthermore, in this embodiment, the number of parts of the handle 420 can be reduced and the configuration can be simplified compared to the first embodiment. Therefore, the drainage pump 400 can obtain a cost advantage 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 part thereof, and for example, as shown in Fig. 7, the first connecting portion 524 may be configured to be connected to one end 522a, 527a of each of the gripping portions 522, 527. Fig. 7 is a perspective view showing a drainage pump 500 according to a modified example of this embodiment. Also, as shown in Fig. 7, the second connecting portion 525 may be configured in a plurality of parts so that both ends of the first connecting portion 524 are respectively connected to the casing 10.

[0056] 7, first connecting portion 524 may be configured to connect to other ends 522b, 527b of gripping portions 522, 527. That is, first connecting portion 524 is connected to both ends of first gripping portion 522 and second gripping portion 527 to form a square-shaped handle.

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

[0058] 8, the drainage pump 600 includes a plurality of handles 620 arranged in parallel on the casing 10, similar to the drainage pump 100 according to the first embodiment. The plurality of handles 620 are specifically 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.

[0059] The gripping portions 622, 627 are provided so as to extend in a direction parallel to the direction of the pump axis C. In this case, the gripping portions 622, 627 are preferably provided so as to be line-symmetrical with respect to the pump axis C in a top view.

[0060] As a result, as in the first embodiment, as shown in Figure 9, when transporting the drainage pump 600, multiple users U1, U2 of the drainage pump 600 can lift and transport the pump by grasping separate gripping portions 622, 627 from both the left and right sides of the drainage pump 600.

[0061] Therefore, the drainage pump 600 can be carried by a plurality of people with the mass of the pump being efficiently shared among them. In other words, the drainage pump 600 can be made more portable for users.

[0062] In detail, compared to the first embodiment (see Figs. 3 and 9 for comparison), in the drainage pump 600 according to this embodiment, the distance between the users U1 and U2 is closer than in the case of the drainage pump 100 according to the first embodiment. Therefore, the users U1 and U2 can share the mass of the drainage pump 600 and transport the drainage pump 600 more efficiently than in the case of 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-rear direction of the users U1 and U2, in the drainage pump 600 according to this embodiment, when the users U1 and U2 throw the drainage pump 600 into the flooded area in front of them, the throwing direction of the drainage pump 600 is along the pump axis C, as compared with the drainage pump 100 according to the first embodiment. As a result, when the users U1 and U2 lift the drainage pump 600 and swing it like a pendulum in the front-rear direction of the users U1 and U2 with their shoulders as a fulcrum to throw the drainage pump 600 into the flooded area, if the momentum at the time of throwing is weak, there is an increased possibility that the suction port 11 or the discharge port 12 of the drainage pump 600 will come into contact with the ground (such as a seawall).

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

[0065] The extending direction of each of the gripping portions 622, 627 may not be strictly parallel to the direction of the pump axis C due to manufacturing variations in the handle 620 and variations in the assembly of the handle 620 to the casing 10.

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

[0067] 10, the drainage pump 700 further includes an annular float 40 having an opening formed therein that opens in the vertical direction in addition to the drainage pump 100 according to the first embodiment. The drainage pump 700 is provided in the casing 10 at intervals such that the multiple gripping portions 22, 27 fit inside the opening.

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

[0069] In many cases where the drainage pump 700 is used in a submerged area, the drainage pump 100 is used while being suspended by the float 40. In this case, the float 40 is floating on the water surface of the submerged area, and the drainage pump 100 is suspended in the water from the float 40. If the drainage pump 700 is used without the float 40, the drainage pump 700 will sink to the bottom of the submerged area and will suck in soil and sand at the bottom through the suction port 11, which may cause a breakdown or the like.

[0070] Conventionally, when a drainage pump connected to a float 40 is introduced into a flooded area, the float 40 is held while the drainage pump 100 is suspended. Since the drainage pump 100 is a heavy object, the entire weight of the drainage pump 100 is placed on the connecting member 42 between the float 40 and the chain member 41 that supports the drainage pump 100 in a suspended state. This causes a problem that the connecting portion between the connecting member 42 and the float 40 is damaged early.

[0071] In contrast, in the drainage pump 700, the float 40 can be placed on the top of the drainage pump 700 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 drainage pump 700 can be gripped from above by users U1, U2 through the opening, as shown in Fig. 12. Fig. 12 is a front view and partial cross-sectional view showing the drainage pump 700 in a transported state.

[0072] Therefore, even when the casing 10 and the float 40 are connected, the drainage pump 700 can be transported by multiple users U1, U2 holding the grips 22, 27, similar to the drainage pump 100 according to the first embodiment. Therefore, the drainage pump 700 can be easily transported by the users U1, U2, similar to the drainage pump 100.

[0073] 12, users U1 and U2 can insert the drainage pump 100 together with the float 40 into the submerged area while holding the gripping portions 22 and 27. Therefore, when inserting the drainage pump 700 into the submerged area, there is no need to hold the float 40. Therefore, since excessive force is not applied to the connecting member 42 between the float 40 and the chain-like member 41, the drainage pump 700 can prevent early damage to the connecting portion between the connecting member 42 and the float 40.

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

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

[0076] 13, the drainage pump 800 has connecting portions 823, 828 that connect the gripping portions 822, 827 to the upper portion of the casing 10. The connecting portions 823, 828 are string-like bodies, specifically, chain-like members.

[0077] Since the connecting parts 823, 828 are chain-shaped members, the drainage pump 800 can connect the gripping parts 822, 827 and the casing 10 with sufficient strength when the drainage pump 800 is transported.

[0078] On the other hand, in a situation where the drainage pump 800 is housed in the bed of the drainage pump vehicle 1, the drainage pump 800 has the connecting parts 823, 828 which are chain-like members, and the chain-like members can be slackened to allow the gripping parts 822, 827 to hang down along the casing 10. Therefore, even if there is a space restriction on the bed of the drainage pump vehicle 1, the drainage pump 800 can be housed in a small occupied space by allowing the gripping parts 822, 827 to hang down along the casing 10.

[0079] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the spirit of the present invention. The drawings are mainly schematic illustrations of each component for ease of understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings are different from the actual ones due to the convenience of drawing. In addition, the material, shape, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a range that does not substantially deviate from the configuration of the present invention.
