Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the conventional drain pipe cleaning system described in Patent Document 1 mentioned above also had the following problems to be solved.

[0006] First, in the case of high-rise apartment buildings such as tower mansions, as shown in FIG. 1, in order to perform cleaning by inserting the water supply hose portion 2 from the side of the cleaning nozzle N into the inside of the drain pipe Pe through the maintenance opening Peu provided on the rooftop Bu, the length (height) of the water supply hose portion 2 inserted into the drain pipe Pe often reaches several tens of meters or more. In this case, usually, the work is carried out by a plurality of workers. However, since the weight of the water supply hose portion 2 reaches about several tens to one hundred [kg], it imposes a great deal of labor and the working time tends to be long.

[0007] Second, during cleaning, the cleaning nozzle N provided at the tip of the water supply hose portion 2 is lowered to a predetermined height inside the drain pipe Pe, and cleaning is performed while pulling up the cleaning nozzle N from this lowered position. In this case, usually, it is carried out depending on the experience and intuition of the worker, so the pulling-up speed is unstable and varies, resulting in variations in the cleaning ability and a concern of insufficient cleaning. Moreover, since the cleaning state cannot be confirmed in real time, there is also a risk of overlooking the cleaning quality and insufficient cleaning. From the viewpoint of ensuring the cleaning quality and further enhancing the reliability and stability, there was room for further improvement.

[0008] An object of the present invention is to provide a high-pressure hose supply machine for a drain pipe cleaning system that solves the problems existing in such a background art.

Embodiments for Carrying Out the Invention

[0022] Next, preferred embodiments according to the present invention will be given and described in detail with reference to the drawings.

[0023] First, with reference to FIG. 1, the overall schematic configuration of the drain pipe cleaning system M including the high-pressure hose supply machine 1 according to the present embodiment will be described.

[0024] The drain pipe cleaning system M has a function of cleaning drain pipes provided in high-rise apartment buildings (buildings) such as tower mansions. FIG. 1 shows a case where a drain pipe Pe installed in a tower mansion B with a height exceeding several tens of meters is cleaned by the drain pipe cleaning system M.

[0025] Reference numeral 80 indicates a vehicle (automobile) equipped with a cleaning machine 80m. The exemplified vehicle 80 is a one-box car, and the cleaning machine 80m is installed inside the one-box car. The cleaning machine 80m includes a water storage tank for storing cleaning water Ws and a delivery pump (high-pressure pump) for delivering the cleaning water Ws. Further, a high-pressure hose supply machine 1 according to the present embodiment is installed on the rooftop Bu of the tower mansion B, and the high-pressure hose supply machine 1 and the cleaning machine 80m are connected by a water supply hose 81. Therefore, the water supply hose 81 and the cleaning machine 80m constitute a water supply device Mp.

[0026] Next, with reference to FIGS. 1-10, the configuration of the high-pressure hose supply machine 1 according to the present embodiment will be specifically described.

[0027] As shown in FIGS. 1-4, the high-pressure hose supply machine 1 is basically configured to include five main units: a frame unit Uf, a hose supply unit Us, a rotation drive unit Ud, a control unit Uc, and a hose guide unit Ug.

[0028] As shown in FIG. 4, the frame unit Uf includes a support frame portion 3s and a base frame portion 3b. The support frame portion 3s and the base frame portion 3b can be configured by combining frame members A made of a hard material such as metal having an L-shaped, U-shaped, or rectangular cross-section.

[0029] The support frame part 3s is configured in a rectangular parallelepiped shape close to a cube by combining a plurality of frame members 3sp..., and if necessary, reinforcing frame members 3sm... are installed between the respective frame members 3sp.... The support frame part 3s has a support function for the hose supply unit Us, the rotation drive unit Ud, the control unit Uc, and the hose guide unit Ug.

[0030] Also, the base frame part 3b is configured in a flat shape by two vertical frame members 3bs, 3bs arranged in parallel and long in the front-rear direction and a plurality of horizontal frame members 3bh, 3bh... installed between the vertical frame members 3bs and 3bs. Note that the horizontal frame members 3bh... arranged at both ends of the vertical frame members 3bs... are used as handles during movement. The upper surface 3bu of the base frame part 3b has a function of supporting the lower end part 3bs of the support frame part 3s, and the length in the front-rear direction Fs, which is the longitudinal direction of the vertical frame members 3bs..., is selected to be approximately twice the length of the support frame part 3s. Since the base frame part 3b has a moving function, a plurality of moving casters 11... are provided at the bottom of the base frame part 3b, and a plurality of stopping stoppers 12... for preventing movement when stopped are provided.

[0031] Furthermore, the base frame part 3b and the support frame part 3s are configured to be detachable. The detaching structure Xc in this case is configured as shown in FIG. 5. That is, the detaching structure Xc includes a pair of bolt parts 14, 14 protruding in a direction perpendicular to the upper surface (fixed surface) 3bu by fixing them at different positions on the upper surface 3bu of the vertical frame member 3bs of the base frame part 3b by welding or the like, insertion hole parts 15, 15 formed at the lower end part 3bs of the support frame part 3s corresponding to the positions of the bolt parts 14, 14, and nut parts 16, 16 that are screwed and fixed to the bolt parts 14 after inserting the bolt parts 14, 14 into the insertion hole parts 15... during assembly. Note that when disassembling (detaching), the nut parts 16, 16 may be loosened and removed. With this detaching structure Xc, it is possible to easily attach and detach while ensuring the positioning function and fixing strength.

[0032] Thus, when constructing the frame unit Uf, if a detachable base frame portion 3b that supports the lower end portion 3bs of the support frame portion 3s on the upper surface 3bu is provided, the frame unit Uf can be separated into two frame portions with different functions and sizes, namely, a support frame portion 3s having a support function and a base frame portion 3b having a moving function, so that it is excellent in multifunctionality and convenience.

[0033] As shown in FIGS. 2 and 3, the hose supply unit Us includes a winding reel portion 4r rotatably supported by a pair of left and right bearing portions 3r, 3r, and a water supply hose portion 2 wound around the winding reel portion 4r. In this case, one of the bearing portions 3r integrally includes a bracket portion 21 that can be placed on the upper end surface of the support frame portion 3s, and a detachable structure similar to the detachable structure Xc of FIG. 5 described above can be provided with respect to the support frame portion 3s. That is, bolt portions 14, 14 may be provided on the support frame portion 3s side, and insertion hole portions 15, 15 may be provided in the bracket portion 21.

[0034] The water supply hose portion 2 is wound around the winding reel portion 4r as it is. The water supply hose portion 2 uses a hose body 2m made of a hose member having excellent pressure resistance and flexibility. This hose body 2m has a washing water intake port to which high-pressure washing water Ws is supplied at one end. This washing water intake port is connected and fixed to a pipe-shaped shaft portion 22 provided at the center of the winding reel portion 4r, and the inside of the washing water intake port and the shaft portion 22 is connected in communication. This shaft portion 22 is rotatably supported by a pair of left and right bearing portions 3r, 3r, and at the outer end of this shaft portion 22, as shown in FIGS. 1 and 3, it also serves as a connection port for connecting the outlet of the water supply hose 81 in the water supply device Mp described above.

[0035] Also, the other end (tip) of the hose body 2m serves as a washing water discharge port 2o, and as shown in FIG. 9, a washing nozzle N for jetting washing water Ws is connected. The exemplary washing nozzle N has a plurality of injection ports Ns... along the circumferential direction, and each injection port Ns... can jet the washing water Ws in an oblique direction with respect to the radial direction of the washing nozzle N. Thereby, the washing nozzle 5n can wash the inner wall Pew of the drain pipe Pe with the high-pressure washing water Ws jetted from the injection ports Ns... while rotating. At the tip of the washing nozzle N, a weight 23 is provided in which a plurality of weight members 23p... are connected in a string-like manner, facilitating entry into the drain pipe Pe.

[0036] The rotation drive unit Ud includes an electric motor 5 that rotationally drives the winding reel portion 4r. A three-phase AC motor 5m is used for the electric motor 5. The high-pressure hose feeder 1 according to the present embodiment uses a general commercial AC power supply of AC100V, but uses a control unit Uc described later to convert it to 200V three-phase AC via an AC / DC converter, an inverter unit, etc. In this way, if a three-phase AC motor 5m is used for the electric motor 5, the advantages of the three-phase AC motor 5m, that is, the torque shortage when rotating the winding reel portion 4r can be eliminated, and the rotational speed control by stepless speed change can also be easily performed.

[0037] As shown in FIG. 4, the rotation drive unit Ud includes a flange portion 24 that supports the electric motor 5. This flange portion 24 is detachably provided with respect to the upper surface of a frame member 3sp located at the lower end of the lower end of the support frame portion 3s. In this case, a detachable structure similar to the detachable structure Xc of FIG. 5 described above can be provided. That is, bolt portions 14, 14 may be provided on the support frame portion 3s side, and insertion hole portions 15, 15 may be provided on the flange portion 24.

[0038] The control unit Uc has a function of controlling the overall operation such as turning on / off the high-pressure hose feeder 1 according to the present embodiment, and also has a function of performing at least drive control for the electric motor 5.

[0039] FIG. 6 shows a front view of the control unit Uc, and FIG. 7 shows a block circuit of the control unit Uc. As shown in FIG. 6, the control unit Uc includes a rectangular parallelepiped casing 26, and a control circuit 27 shown in FIG. 7 is built therein. An operation panel 26p is disposed on the front surface of the casing 26. Rubber feet 26s are provided on the bottom surface of the casing 26, and a handle portion 26h is attached to the top surface. Thus, as shown in FIG. 2, the control unit Uc is supported by the support frame portion 3s by hanging the handle portion 26h on the hook portions 28, 28 provided on the support frame portion 3s.

[0040] As shown in FIG. 6, the operation panel 26p includes a hose length counter 31, a counter reset switch 31s, a rotation speed adjustment dial 32, a reel rotation direction / stop changeover switch 33, and a main switch 34. Further, the rear panel 26r includes a power input portion 35 shown in FIG. 7, a foot switch 36 for the motor, and a sensor connection portion 37 for hose counting.

[0041] Furthermore, as shown in FIG. 7, the control circuit 27 includes a main control circuit 41 using a microcomputer. The reel rotation direction / stop changeover switch 33 and the main switch 34 described above are connected to the main control circuit 41. On the other hand, the AC 100V applied to the power input portion 35 described above is converted to DC 12V by an AC / DC converter 42 and applied to the main control circuit 41. An inverter unit 43 is also provided. AC 100V is applied to the input side of the inverter unit 43, three-phase 200V is output, and is applied to the three-phase AC motor 5m via a switch circuit 44. Further, the rotation speed adjustment dial 32 described above is connected to the inverter unit 43 via an adjustment circuit 45, and the hose length counter 31 is connected to the inverter unit 43 via the adjustment circuit 45.

[0042] Thus, when configuring the control unit Uc, by detecting the rotation of the take-up reel unit 4r or the rotation of the guide roller unit 6m..., a display function unit 7 that displays the length of the water supply hose unit 2 during feeding or winding based on at least the detected amount of rotation is provided. Since the operator can numerically visually recognize the length during feeding or winding by the display function unit 7, the feeding state or winding state of the water supply hose unit 2 can be easily and accurately grasped. Further, if a rotational speed adjustment unit 8 that varies the rotational speed by controlling the rotational drive unit Ud is provided, the operator can accurately grasp the moving speed of the water supply hose unit 2 that relied on the operator's experience and intuition, particularly the setting and grasping of the speed of the pulling-up speed. Therefore, variations in cleaning ability can be prevented and the stabilization of cleaning quality can be achieved.

[0043] The hose guide unit Ug is configured using one or two or more (exemplified as three) guide roller units 6m, 6a, 6b that guide the water supply hose unit 2 fed out from the take-up reel unit 4r or the water supply hose unit 2 wound around the take-up reel unit 4r. As shown in FIGS. 3 and 1, it is detachably provided on the front of the support frame unit 3s via a pair of left and right mounting frames 51p, 51q. In this case, a detachment structure similar to the detachment structure Xc of FIG. 5 described above can be provided. That is, bolt portions 14, 14 may be provided on the support frame unit 3s side and insertion hole portions 15, 15 may be provided on the mounting frame 51 side.

[0044] As shown in Fig. 2, the hose guide unit Ug includes a pair of support plates 52p and 52q facing each other left and right, and three rotatable guide roller portions 6m, 6a, and 6b are arranged between the support plates 52p and 52q. In this case, the relatively large-diameter intermediate guide roller portion 6m is directly supported by the support plates 52p and 52q. Also, at the front side of the guide roller portion 6m, one ends of a pair of left and right pivot levers 53p and 53q rotatably supported by the support plates 52p and 52q are respectively provided, and a small-diameter front guide roller portion 6a is rotatably provided between the other ends of the pair of pivot levers 53p and 53q. Further, at the rear side of the guide roller portion 6m, one ends of a pair of left and right pivot levers 54p... rotatably supported by the support plates 52p and 52q are respectively provided, and a small-diameter rear guide roller portion 6b is rotatably provided between the other ends of the pair of pivot levers 54p.... Then, springs 55p... are installed on the pivot levers 53p... to bias the front guide roller portion 6a to press against the water supply hose portion 2, and springs 56p... are installed on the pivot levers 54p... to bias the rear guide roller portion 6b to press against the water supply hose portion 2. Note that 57... indicates a plurality of reinforcing frames installed between the support plates 52p and 52q.

[0045] In this way, if a hose guide unit Ug is provided that is configured to be detachable from the frame unit Uf and uses one or more guide roller portions 6m, 6a, and 6b to guide the water supply hose portion 2 fed out from the take-up reel portion 4r or the water supply hose portion 2 wound around the take-up reel portion 4r, the feeding or winding of the water supply hose portion 2 can be guided by the guide roller portions 6m, 6a, and 6b. Therefore, the stability and further the safety when moving the water supply hose portion 2 during use can be ensured.

[0046] On the other hand, the water supply hose section 2 can be provided with a camera unit Uv that photographs the inside of the drain pipe Pe and is detachable from the cleaning nozzle N. This camera unit Uv is not connected to the control unit Uc and functions independently as a single device. FIG. 8 shows the external configuration of this camera unit Uv. The camera unit Uv includes a housing section 61 that covers the whole, and on the front panel 61f of this housing section 61, from the upper side to the lower side, there are provided a waterproof opening / closing cover 62a for the battery case, a power switch 62b, and an antenna plate 62c. On the lower surface of the housing section 61, there are provided a camera section 63a facing downward and LED light sections 63b and 63c arranged on both sides of this camera section 63a.

[0047] Also, the attachment / detachment structure Xn between the camera unit Uv and the cleaning nozzle N is shown in FIG. 9. Since the tip of the cleaning nozzle N is provided with a weight 23 in which a plurality of weight members 23p... are connected in a string-of-beads manner, a weight storage chamber 64 is provided at the upper end of the housing section 61 in the camera unit Uv, and the weight member 23p located at the lower end can be stored and attached inside this weight storage chamber 64.

[0048] Furthermore, inside the housing section 61 of the camera unit Uv, a control system circuit 65 shown in FIG. 10 is incorporated. The control system circuit 65 includes a control section 65m using a microcomputer. The camera section 63a and the LED light sections 63b and 63c arranged on the left and right, which were described above, are connected to this control section 65m, and a communication section 9 capable of short-distance communication wirelessly is also connected. In this embodiment, since a short-distance communication method that does not use the Internet is used as the communication method, reliable transmission and reception are possible. The antenna plate 62c described above is connected to this communication section 9. 65b is a battery and is connected to the control section 65m and the communication section 9. Therefore, by providing such a camera unit Uv, problems such as insufficient cleaning can be surely avoided, and thus the cleaning quality and the reliability during cleaning can be further improved.

[0049] In addition, since the camera unit Uv includes the communication unit 9, as shown in FIG. 10, data transmission and reception processing can be performed with an external communication device, for example, a smartphone 71 carried by an operator. In this case, an internal image of the drain pipe Pe can be displayed on the display 71d of the smartphone 71 based on the captured image data sent from the camera unit Uv, and various operations on the camera unit Uv can be performed by the operation unit 71h including various operation keys displayed thereon. In this way, if the camera unit Uv is provided with the communication unit 9 capable of transmitting the captured image data by a wireless communication method, the operator can check the cleaning state in real time, so that necessary measures can be taken promptly and necessary analysis and the like can be performed by recording or the like.

[0050] As described above, as shown in FIG. 4, the high-pressure hose feeder 1 includes five units, namely, a frame unit Uf, a hose supply unit Us, a rotation drive unit Ud, a control unit Uc, and a hose guide unit Ug. The hose supply unit Us, the rotation drive unit Ud, the control unit Uc, and the hose guide unit Ug can be assembled or disassembled with respect to the frame unit Uf. Further, the frame unit Uf can be assembled or disassembled with a support frame portion 3s and a base frame portion 3b. Therefore, even in a high-rise building or the like having a narrow passage or an entrance / exit, the high-pressure hose feeder 1 can be carried in disassembled form and assembled and used on a rooftop or the like, so that it can be easily carried and the usable places can be dramatically expanded, enhancing the versatility.

[0051] Next, the overall usage method of the drain pipe cleaning system M including the usage method of the high-pressure hose feeder 1 according to the present embodiment will be described with reference to each drawing according to the flowchart shown in FIG. 11.

[0052] Now, assume a case where a drain pipe Pe having a length (height) exceeding several tens of meters installed in the tower mansion B shown in FIG. 1 is cleaned by the drain pipe cleaning system M.

[0053] First, necessary equipment including each necessary unit part Us... is carried to the rooftop Bu of the tower mansion B (step S1). That is, the disassembled support frame part 3s, base frame part 3b, hose supply unit Us, rotation drive unit Ud, control unit Uc, and hose guide unit Ug, and further, a water supply hose 81, etc. are carried in.

[0054] And if the carrying-in of the equipment is completed, assembly is performed (step S2). First, the support frame part 3s is installed on the base frame part 3b and fixed by the detachable structure Xc. Note that the reference numeral 76... shown in FIG. 3 indicates a reinforcing column obliquely installed between the base frame part 3b and the support frame part 3s.

[0055] Also, the hose supply unit Us, rotation drive unit Ud, control unit Uc, and hose guide unit Ug are assembled to the support frame part 3s. In this case, when assembling the rotation drive unit Ud, as shown in FIG. 3, an endless transmission chain 74b is bridged between the sprocket 74r of the hose supply unit Us and the sprocket 74d of the rotation drive unit Ud to complete the rotation transmission mechanism. After completion, as shown in FIG. 2, the entire rotation transmission mechanism is covered by attaching a safety cover 75. Note that the sprocket 74r and the sprocket 74d may be in a pre-attached state or may be attached on-site (rooftop Bu).

[0056] As a result, the basic structure shown in FIG. 3 is completed. Once the basic structure is completed, electrical connections are made between the rotary drive unit Ud, the control unit Uc, and the hose guide unit Ug using cables or the like. Through the above assembly operations, the high-pressure hose feeder 1 shown in FIGS. 1 and 2 that can be used in a tower mansion B or the like can be obtained. Thus, in the high-pressure hose feeder 1 according to the present embodiment, the hose supply unit Us, the rotary drive unit Ud, and the control unit Uc are configured to be attachable or detachable to / from the frame unit Uf. Therefore, even in a high-rise building having narrow passageways, entrances and exits, etc., it can be carried in disassembled form and assembled and used on a rooftop or the like. As a result, it can be easily carried, and the places where it can be used are dramatically expanded, enhancing its versatility.

[0057] Next, as shown in FIG. 1, the water outlet of the water supply hose 81 in the water supply device Mp is connected to the connection port at the outer end of the shaft portion 22 of the hose supply unit Us, and the water supply hose 81 is lowered outside the tower mansion B, and the water inlet is connected to the washer 80m mounted on the vehicle 80.

[0058] After that, the water supply hose portion 2 is set (step S3). In this case, for the setting of the water supply hose portion 2, as shown in FIG. 3, the side of the water supply hose portion 2 provided with the cleaning nozzle N is passed below (or above) the rear guide roller portion 6b, above (or below) the intermediate guide roller portion 6m, and below (or above) the front guide roller portion 6a, and the tip side of the water supply hose portion 2 may be set near the inner upper end of the maintenance opening Peu of the drain pipe Pe installed on the rooftop Bu.

[0059] Since the preparation is completed as described above, after switching the reel rotation direction / stop changeover switch 33 of the control unit Uc to the pay-out side, the main switch 34 (or the foot switch 36) is switched to the ON side (step S4).

[0060] As a result, the electric motor 4 operates, and the take-up reel section 4r rotates in the payout direction at the set rotational speed. Corresponding to this rotational operation, the water supply hose section 2 is displaced downward inside the drain pipe Pe (step S5). At this time, since the hose length counter 31 of the control unit Uc displays the length of the hose paid out, the operator checks the hose length counter 31. If the target length is reached, the operator switches the main switch 34 to the OFF side to stop the electric motor 4 (steps S6, S7). FIG. 1 shows this state.

[0061] Next, the water supply is started by operating the cleaning machine 80m or by switching an on-off valve (not shown) to the open side (step S8). As a result, the cleaning water Ws is supplied to the cleaning nozzle N through the cleaning machine 80m, the water supply hose 81, and the hose body 2m of the water supply hose section 2. Then, as shown in FIG. 9, the cleaning water Ws is jetted from each jet port Ns... and the cleaning process inside the drain pipe Pe is performed (step S9). At this time, when the camera unit Uv is attached, the photographing process of the inside of the drain pipe Pe by the camera unit Uv is performed (step S10). The photographed image data is transmitted to a smartphone 71 or the like carried by the operator. As a result, the operator can surely avoid problems such as insufficient cleaning, so that the cleaning quality and the reliability during cleaning can be further improved. In addition, since the camera unit Uv is provided with a communication unit 9 capable of transmitting the photographed image data by a wireless communication method, the operator can check the cleaning state in real time, can promptly take necessary measures, and can perform necessary analysis or the like by recording or the like.

[0062] Also, together with the start of the water supply, the reel rotation direction / stop changeover switch 33 is switched to the take-up side. As a result, the take-up reel section 4r rotates in the take-up direction at the optimum rotational speed set, and corresponding to this rotation, the water supply hose section 2 ascends in the drain pipe Pe at a constant speed (step S11). At this time, the operator checks the hose length counter 31, and the target height, that is, If it has risen up to near the maintenance opening Peu, stop the electric motor 4 by switching the main switch 34 to the OFF side (Steps S12, S13).

[0063] When the operator can determine that the cleaning is being performed well through real-time monitoring of the cleaning state, the cleaning process is terminated (Step S14). On the other hand, if there are parts that seem to have poor cleaning, the same cleaning process can be repeated again (Steps S14, S4…). Note that the cleaning state can also be confirmed by lowering or raising only the water supply hose part 2 on the cleaning nozzle N side equipped with the camera unit Uv with the water supply stopped after the cleaning process.

[0064] Upon completion of the cleaning process, switch the main switch 34 to the ON side again to operate the electric motor 4, rotate the take-up reel part 4r in the take-up direction, and separate the water supply hose part 2 from the drain pipe Pe to recover the water supply hose part 2 (Step S15). After that, if there are other drain pipes Pe to be cleaned, the cleaning work may be performed according to the same processing procedure.

[0065] On the other hand, if all the cleaning work is completed, disassemble the high-pressure hose supply machine 1 (Step S16). The disassembly is performed in the reverse procedure of the assembly. As shown in FIG. 4, disassemble it into each unit Us…, and disassemble the frame unit Uf into the base frame part 3b and the support frame part 3s. Then, carry out the equipment including the disassembled units Us… from the rooftop Bu (Step S17).

[0066] Therefore, such a high-pressure hose feeder 1 according to this embodiment basically includes a frame unit Uf having a support frame portion 3s, a winding reel portion 4r rotatably supported by a bearing portion 3r fixed in position with respect to the support frame portion 3s, and a hose supply unit Us having a water supply hose portion 2 wound around the winding reel portion 4r, a rotation drive unit Ud using an electric motor 5 for rotationally driving the winding reel portion 4r, and a control unit Uc for performing drive control at least on the electric motor 5. Thus, even when the weight of the water supply hose portion 2 reaches about several tens to one hundred [kg], since the feeding or winding can basically be performed by power, an operator can work alone, etc., the working labor can be dramatically reduced, and it can contribute to shortening and improving the efficiency of the working time.

[0067] As described above in detail with respect to the preferred embodiment, the present invention is not limited to such an embodiment, and can be arbitrarily changed, added, or deleted in terms of the detailed configuration, shape, method, quantity, numerical value, etc., without departing from the gist of the present invention.

[0068] For example, in the case where the frame unit Uf is provided with a detachable base frame portion 3b that supports the lower end portion 3sd of the support frame portion 3s on the upper surface 3bu, the length of the base frame portion 3b may be configured to be short, or the moving casters 11... etc. may be directly attached to the lower end portion 3sd of the support frame portion 3s, so that the base frame portion 3b may not be used. Also, the hose guide unit Ug that guides the water supply hose portion 2 fed out from the winding reel portion 4r or the water supply hose portion 2 wound around the winding reel portion 4r using one or two or more guide roller portions 6m, 6a, 6b is not an essential component and does not necessarily need to be provided, and can be replaced by components having other similar functions. Further, although it is desirable to use a three-phase AC motor 5m for the electric motor 5, an AC100V drive electric motor may be used if the necessary characteristics can be ensured when the electric motor 5 is an AC100V drive motor. In the case where the control unit Uc is provided with a display function unit 7 that displays the length of the water supply hose portion 2 during feeding or winding based on at least the detected rotation amount by detecting the rotation of the winding reel portion 4r or the rotation of the guide roller portion 6m..., it is not an essential component, such as converting the rotation amount of the electric motor 5 or using a separate detection sensor. On the other hand, although the cleaning machine 81m in the drain pipe cleaning system M is shown when mounted on the automobile 80, various types of cleaning machines can be used, such as a self-propelled cleaning machine, and although the smartphone 71 is exemplified, it can be replaced by various similar devices such as a notebook computer.
