  The present invention relates mainly to a vehicle deposit removing device for removing vehicle deposits.

  2. Description of the Related Art Conventionally, workers sometimes manually remove vehicle deposits (such as mud and snow) using a tool or a device. Also known are devices for automatically removing vehicle deposits.

  Patent Document 1 discloses an apparatus for automatically removing snow attached to a railway vehicle. This device is arranged on the outside of the rail of a rail car and comprises a spray unit. The spray unit removes snow deposition by injecting compressed air to a running railway vehicle.

JP 2004-51020 A

  The configuration for injecting compressed air as in Patent Document 1 may not be able to remove the deposits firmly attached to the vehicle because the amount of energy is limited. Here, when high pressure water is jetted instead of compressed air to remove deposits, if the high pressure water hits an electronic device, for example, the electronic device may be damaged.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is the removal of vehicle deposits that can sufficiently remove the deposits on the vehicle and suppress the water from being applied to electronic devices and the like. It is in providing an apparatus.

  The problem to be solved by the present invention is as described above, and next, means for solving the problem and its effect will be described.

  According to an aspect of the present invention, there is provided a vehicle attached matter removing device having the following configuration. That is, the vehicle attached matter removing apparatus includes a high pressure pump, a water injection unit, a shutter, a rotational drive unit, and a control device. The direction of the injection port is fixed, and the water injection unit injects the water delivered by the high-pressure pump from the injection port toward the lower part of the traveling vehicle. The shutter covers an injection port of the water injection unit and an opening is formed. The rotational drive unit rotationally drives the shutter. The control device controls the rotation drive unit to block the water jetted by the water jet unit from being blocked by the shutter, and the water jetted by the water jet unit flows through the opening to the vehicle It is possible to switch between the injection state to be injected.

  Thereby, the presence or absence of water injection can be switched at high speed by rotationally driving the shutter and switching between the blocking state and the injection state. Therefore, while preventing the water from being jetted to the unnecessary part of the lower part of the traveling vehicle, it is possible to jet the water to the necessary part to remove the deposit.

  According to the present invention, it is possible to realize a vehicle attached matter removing device capable of sufficiently removing the attached matter of a vehicle and capable of suppressing the application of water to an electronic device or the like.

  Next, embodiments of the present invention will be described with reference to the drawings. First, the outline of the snow removal device 10 according to the first embodiment will be described with reference to FIG. FIG. 1 is a schematic view showing how the snow removal device 10 of the first embodiment is used.

  The snow removal device (vehicle attached matter removing device) 10 is a device for removing snow (adhered matter) attached to the lower part of the railway vehicle 100. As shown in FIG. 1, the railcar 100 includes a car body 101, a truck 102, and wheels 103. In the railcar 100, when traveling in an area where snow is piled, the snow bounces up by the wheels 103, and the snow adheres to the rear or upper side of the wheels 103 (that is, the lower part of the railcar 100) of the vehicle body 101. The lower part of the railcar 100 is a concept including not only the lower surface and the lower end of the railcar 100 but also the periphery thereof. Since the wheels 103 are rotating at high speed, snow is jumped up in a very energetic state, and snow adhering to the lower part of the railcar 100 (hereinafter, snowfall) becomes hard. Therefore, if snowfall falls temporarily while the railcar 100 is traveling, the snowfall may collide with the ballast etc. and the ballast may be bounced up to collide with the surroundings or the railcar 100 may be damaged. .

  The snow removal device 10 according to the present embodiment removes the snow deposition on the lower part of the railway vehicle 100 by injecting water using a water jet to hit the snow deposition. In the present embodiment, in order to perform snow removal in a short time, the snow removal is performed by injecting water to the running railway vehicle 100. Here, at the lower part of the railcar 100, a large number of electric devices such as an electric motor and a transformer for driving the wheels 103 are arranged. Although these electrical devices are waterproof, it is not desirable to apply high pressure water. Therefore, in the case of removing snow by putting the water on the traveling railway vehicle 100, it is necessary to switch the presence or absence of the injection at a high speed and at a proper timing. Here, in the configuration in which the presence or absence of the injection is switched by the valve provided to the water jet device, it is difficult to switch the valve at high speed, so it is difficult to apply water only to the snow covered portion without applying water to the electric device Alternatively, the traveling speed of the railway vehicle 100 needs to be very low).

  In consideration of this point, in the present embodiment, the water jet is switched by passing or blocking the water by a separate member (a shutter 14 described later), thereby switching the presence or absence of the water jet. Hereinafter, the details will be described with reference to FIGS. 1 to 6. Moreover, while showing the snow removal apparatus 10 typically in FIGS. 2-4, description of the support structure of each part, an attachment structure, etc. is abbreviate | omitted so that a structure may become intelligible.

  As shown in FIG. 2 (a), the snow removal device 10 has a high pressure pump 11, a water injection unit 12, a shutter 14, and a shutter drive motor (rotation drive unit) as a configuration for injecting water to the railway vehicle 100. And 17.).

  The high pressure pump 11 delivers the supplied (sucked) water at a high pressure (for example, 5 MPa to 20 MPa). The water delivered by the high pressure pump 11 may be cold water or hot water. Also, it may be fresh water or water containing an agent related to snow removal. The water delivered by the high-pressure pump 11 is supplied to the water injection unit 12 via a water supply pipe schematically shown in FIG. 2 (a).

  In the water injection part 12, as shown in FIG. 2 (b), FIG. 3 (b), and FIG. 4 (b), the injection port 13 is formed. The water injection unit 12 performs snow removal of the railcar 100 by injecting high-pressure water supplied from the high-pressure pump 11 from the injection port 13 toward the lower part of the railcar 100. The snow removal device 10 includes a plurality of water injection units 12 whose positions are fixed. As shown in FIGS. 2 (a) and 4 (a) etc., the plurality of water injection units 12 are arranged side by side in the vehicle left-right direction.

  Further, the water injection unit 12 is a water injection unit 12 (12a) in which the injection port 13 is directed upward in the vertical direction, and the water injection unit 12 (12b) in which the injection port 13 is inclined in the vehicle longitudinal direction with respect to the vertical direction The water injection part 12 (12c) which the injection opening 13 inclines in the vehicle left-right direction with respect to the perpendicular direction upper side is included. In the following description, when the reference numerals 12a to 12c are given and described, it is assumed that the water injection portion 12 in which the injection port 13 faces in each of the above directions. Here, the direction of the injection port 13 is the direction of the axial direction of the opening constituting the injection port 13 (that is, the direction of the central axis direction when the injection port 13 is circular). Therefore, the direction of the injection port 13 and the direction in which the water is injected are the same.

  The water injection unit 12a injects water upward in the vertical direction. Thereby, it is possible to remove the snow on the lower surface of the railway vehicle 100 (for example, the snow-covered surface 100 a of FIG. 3A). The water jetted by the water jet unit 12a is not limited to the horizontal plane, but also hits an inclined plane (except for the vertical plane) inclined with respect to the horizontal plane, so snow removal can be performed also on the inclined plane. In the water injection unit 12a, it is difficult to apply water sufficiently to a surface perpendicular to the vehicle longitudinal direction or the vehicle lateral direction (and a surface at an angle close thereto).

  The water injection unit 12b injects water by inclining in the longitudinal direction of the vehicle with respect to the upper side in the vertical direction (that is, approaching the front or rear of the vehicle as the injected water approaches the railway vehicle 100). It is possible to efficiently remove snow on a surface perpendicular to the longitudinal direction of the vehicle and a surface at an angle close to that (for example, the snow-covered surface 100b in FIG. 3A). Further, since the railcar 100 travels in front of the vehicle, snow removal can be performed over a wide range of the snow-covered surface 100b even if the inclination angle of the water injection unit 12b is fixed.

  The water injection unit 12c is inclined in the left-right direction of the vehicle with respect to the upper side in the vertical direction to inject water, whereby a surface perpendicular to the left-right direction of the vehicle and a surface having an angle close thereto (for example Snow removal on the surface 100c) can be performed efficiently. In addition, since the water injection part 12 is arranged side by side in the vehicle left-right direction, when making the injection port 13 incline in the vehicle left-right direction, it may interfere with the water which another water injection part 12 injected. In this respect, in the present embodiment, as shown in FIG. 2A and FIG. 3, the water injection unit 12 c is different in position in the vehicle front-rear direction from the adjacent water injection unit 12 a. Thereby, even when the water injection unit 12c and the adjacent water injection unit 12a simultaneously inject water, interference between the injected water can be prevented.

  The shutter 14 is a semi-cylindrical member (that is, an arc-shaped cross section cut in a plane perpendicular to the left-right direction of the vehicle) as shown in FIG. 5A. The shutter 14 is disposed so that the cylinder axis direction coincides with the left-right direction of the vehicle, and collectively covers the injection ports 13 of the plurality of water injection units 12 as shown in FIG. 4A and FIG. There is. The shutter 14 is formed with an opening 15 as shown in FIGS. 4 to 6 and the like. The opening 15 is formed to apply the water jetted by the water jet unit 12 to the railcar 100 at a predetermined timing. The shutter 14 is attached to a member (not shown) so as to be able to rotate around a cylindrical axis direction (vehicle left-right direction) as a rotation axis.

  Further, as shown in FIG. 4, a partition portion 16 is formed between the water injection portions 12 adjacent to each other in the shutter 14. The partition portion 16 is a plate-like member formed to extend downward from the upper inner wall of the shutter 14. The partition unit 16 prevents the water jetted by the water jet unit 12 and blocked by the shutter 14 from being applied to another (for example, adjacent) water jet unit 12.

  The water injection portion 12 and the shutter 14 are disposed not only between the pair of left and right rails 51 for the railway vehicle 100 to travel but also outside the rails 51. In addition, the water injection unit 12 and the shutter 14 are disposed at positions that do not interfere with the traveling railway vehicle 100 because the water injection unit 12 injects water from below onto the traveling railway vehicle 100. Specifically, as shown in FIG. 3A and the like, the water jet unit 12 and the shutter 14 are between the sleepers 52, and the height at which the sleepers 52 are disposed, or the ballast 53 below the same. Is placed at the height at which it is placed. In addition, the position of the water injection part 12 of this embodiment and the shutter 14 is an example, and may be arrange | positioned in the position different from this embodiment. For example, the water injection unit 12 and the shutter 14 may be disposed outside in the left-right direction of the railcar 100. In this case, the water injection unit 12 injects water by inclining in the left-right direction of the vehicle as the water injection unit 12c described above.

  The shutter drive motor 17 shown in FIG. 4A is an electric motor (for example, a servomotor) that rotationally drives the shutter 14. The shutter drive motor 17 is controlled by a controller 18 shown in FIG. Specifically, the shutter drive motor 17 rotates the drive shaft by the rotation angle instructed by the control device 18 at the rotation speed instructed by the control device 18. The shutter drive motor 17 is disposed outside the shutter 14 in the left-right direction of the vehicle. The drive shaft of the shutter drive motor 17 is fixed so as to be relatively non-rotatable relative to the lateral end (specifically, the cylindrical center position) of the shutter 14 directly or through another member. With this configuration, by driving the shutter drive motor 17, the shutter 14 can be rotated about the cylindrical axial direction (vehicle left-right direction). In the following description, a value (angle) indicating how much the shutter 14 has been rotated may be referred to as a rotational phase.

  When the shutter drive motor 17 rotates the shutter 14, as shown in FIG. 6, the shutter 14 is in a blocking state in which the water jetted by the water jet unit 12 is blocked, and the water jetted by the water jet unit 12 is an opening It is possible to switch between the injection states injected through 15. Moreover, as shown to Fig.5 (a), in this embodiment, several opening part 15 is formed in the vehicle left-right direction. Each opening 15 corresponds to the water injection unit 12 arranged side by side in the vehicle left-right direction. That is, the interval in the vehicle left-right direction of the water injection unit 12 (injection port 13) and the interval in the vehicle left-right direction of the opening 15 of the shutter 14 coincide with each other. Further, in the present embodiment, in the vehicle left-right direction of the shutter 14, at least one of the number of openings 15 formed and the length of the opening 15 in the vehicle front-rear direction is different. According to this configuration, it is possible to differ the timing at which the plurality of water injection units 12 inject water to the railway vehicle 100.

  In FIG. 5 (b), when the shutter 14 having the opening 15 shown in FIG. 5 (a) is rotated as it is, a region where water is jetted to the railway vehicle 100 (a water jet region, ie snow removal) (Area in which the Since the railway vehicle 100 is traveling, a water injection area having a shape extending in the longitudinal direction of the vehicle is displayed in FIG. 5B. As shown in FIG. 5A, the number of openings 15 formed and the length of the openings 15 in the vehicle front-rear direction are different in the vehicle left-right direction of the shutter 14, as shown in FIG. 5B. Thus, the position where snow removal of the railway vehicle 100 can be made different in the vehicle left-right direction. Therefore, by forming the opening 15 in consideration of the expected snow deposition location and the electrical device disposition location, water is sprayed to the portion where the possibility of snow deposition is likely to occur, and the water is delivered to the portion where the electrical devices etc. are disposed. Can be prevented from being injected.

  Further, as shown in FIG. 5A, the shutter 14 has a portion in which a plurality of openings 15 are formed in the longitudinal direction of the vehicle. As shown in FIG. 5 (b) and FIG. 6, the water injection unit 12 disposed in this portion rotates the shutter 14 in a single direction, so that the water injection unit 12 makes the railway vehicle 100 twice (the first injection Timing and second injection timing) water is injected. In the present embodiment, it is assumed that the same railcar 100 is removed at both the first injection timing and the second injection timing. Therefore, it is necessary to reverse the shutter 14 in order to inject water to the second rail vehicle 100 after the first rail vehicle 100 is injected with water twice. Instead of this configuration, water may be injected to the first rail car 100 at the first injection timing, and water may be injected to the second rail car 100 at the second injection timing.

  Further, as shown in FIGS. 2 to 4, the snow removal device 10 includes a water receiving unit 19 and a water storage unit 20 as a configuration for collecting the water injected to the railway vehicle 100.

  The water receiving unit 19 is a member that receives the water injected by the water injection unit 12 and sends the water to the water storage unit 20. The water receiver 19 is disposed below the railway vehicle 100 traveling in the vertical direction of the vehicle. Further, the water receiving portion 19 is disposed in an area (area wider than the arrangement interval of the sleepers 52) wider than the shutter 14 in the vehicle longitudinal direction. With this configuration, it is possible to receive the water injected by the water injection unit 12b in which the injection port 13 is inclined in the front-rear direction of the vehicle with respect to the upper side in the vertical direction, or the water ejected by the water injection unit 12 and scattered. Moreover, the water receiving part 19 is a container-like member, and the water discharge hole is formed in the lower part. The first water storage unit 21 of the water storage unit 20 is disposed below the water discharge hole.

  The first water storage unit 21 temporarily stores the water jetted by the water injection unit 12 and collected directly or via the water receiving unit 19 and sends it to the second water storage unit 22. The first water storage portion 21 is formed in a portion including the lower side of the sleeper 52 in the vehicle vertical direction. In addition, the first water storage unit 21 is disposed between the adjacent sleepers 52 in the vehicle longitudinal direction. With this configuration, if the ballast 53 between the sleepers 52 is removed, the first water storage unit 21 can be installed. Therefore, the first water storage unit 21 can be installed without changing the arrangement of the sleepers 52. Therefore, the snow removal device 10 can be installed at low cost. A second water storage unit 22 is disposed on the outer side of the first water storage unit 21 in the left-right direction of the vehicle.

  The second water storage unit 22 stores the water sent from the first water storage unit 21. The second water storage unit 22 is disposed outside the running railway vehicle 100 in the left-right direction of the vehicle. With this configuration, when there is a space on the outside in the vehicle left-right direction of the sleepers 52, the second water storage portion 22 can be installed without touching the sleepers 52 or the like. Further, the water stored in the second water storage unit 22 is sucked by the low pressure pump 24 through the filter 23 and is delivered to the water injection unit 12 by the high pressure pump 11. With the above configuration, the water jetted by the water jet unit 12 can be reused, so the amount of water consumption can be reduced.

  Next, control performed by the control device 18 will be described with reference to FIGS. 1, 7 and 8. As shown in FIG. 1, a first vehicle detection sensor (approach sensor) 31, a second vehicle detection sensor 32, and a third vehicle detection sensor 33 are sequentially arranged from the upstream side in the traveling direction on the traveling route of the railway vehicle 100. It is arranged. The first vehicle detection sensor 31, the second vehicle detection sensor 32, and the third vehicle detection sensor 33 are position sensors (for example, optical sensors), and an object (specifically, the railway vehicle 100) exists on the detection area The detection result is transmitted to the control device 18.

  Hereinafter, the flow of the process performed by the control device 18 (in particular, the process until the start of snow removal) will be described along the flowchart of FIG. 8. The control device 18 receives the detection of the railway vehicle 100 from the first vehicle detection sensor 31 (S101). Here, the first vehicle detection sensor 31 is disposed significantly upstream of the water injection unit 12. For example, the first vehicle detection sensor 31 is disposed at a position at least one or two or more away from the water injection unit 12 in the longitudinal direction of the railcar 100. The control device 18 starts the high pressure pump 11 (increases the output from 0 to a target value) at the timing when the first vehicle detection sensor 31 detects the railway vehicle 100 (S102).

  With this configuration, the output of the high-pressure pump 11 can be increased to a target value before the railway vehicle 100 passes above the water injection unit 12. In addition, it is not necessary to keep the output of the high pressure pump 11 constantly high. Instead of this configuration, the high pressure pump 11 may be driven with a low output, and the output of the high pressure pump 11 may be increased to a target value at the timing when the first vehicle detection sensor 31 detects the railway vehicle 100.

  Next, the control device 18 receives the detection results of the second vehicle detection sensor 32 and the third vehicle detection sensor 33 (the detection time of the railway vehicle 100), and calculates the vehicle speed of the railway vehicle 100 (S103). Here, the arrangement interval of the second vehicle detection sensor 32 and the third vehicle detection sensor 33 is predetermined. Therefore, the control device 18 takes time from the detection of the railway vehicle 100 (for example, the wheel 103) by the second vehicle detection sensor 32 to the detection of the railway vehicle 100 (for example, the wheel 103) by the third vehicle detection sensor 33. The speed of the railway vehicle 100 can be detected by using the above-mentioned arrangement intervals. The second vehicle detection sensor 32 and the third vehicle detection sensor 33 may be disposed in the vicinity (for example, 3 m or more and 20 m or less) of the water injection unit 12 because the vehicle speed of the rail vehicle 100 may constantly change. preferable.

  Next, the control device 18 calculates and sets a target rotational speed of the shutter 14 (shutter drive motor 17) according to the calculated vehicle speed (S104). That is, as described above, since the opening 15 is formed in consideration of the expected snow deposition location and the electrical device disposition location, the faster the vehicle speed of the railway vehicle 100 is, the more quickly the presence or absence of water injection is switched (ie, , The target rotational speed of the shutter 14 needs to be increased).

  The third vehicle detection sensor 33 also functions as a sensor that detects the position of the railcar 100. That is, as described above, since the opening 15 is formed in consideration of the snowfall expected location and the electrical device arrangement location, it is necessary to start the rotation of the shutter 14 at an appropriate timing. Therefore, the control device 18 calculates and sets the rotation start timing of the shutter 14 based on the detection result of the third vehicle detection sensor 33 (S105).

  Next, when the rotation start timing calculated in step S105 comes (S106), the control device 18 activates the shutter drive motor 17 (S107), and rotates the shutter 14 at the target rotational speed obtained in step S104. Let Further, the control device 18 opens the valve of the water injection unit 12 to inject water before the start of the rotation of the shutter 14. Thereby, snow removal of the railcar 100 by the water injection part 12 can be started. The control device 18 may calculate the vehicle speed again even after the start of snow removal, and change the rotational speed of the shutter 14 according to the calculated vehicle speed. In addition, the control device 18 ends the snow removal at a predetermined time after the start of the snow removal, or at a predetermined time after the third vehicle detection sensor 33 does not detect the railway vehicle 100 (that is, The driving of the high pressure pump 11 and the shutter drive motor 17 is stopped).

  Further, in the present embodiment, snow removal is performed for all of the rail vehicles 100 constituting one formation, but snow removal may be performed only for one or a plurality of rail vehicles 100 on the leading side with many snow deposits. good.

  Next, a second embodiment will be described with reference to FIG. FIG. 9 is an explanatory view showing the configuration and the operation of the blocking member 61 provided in the snow removal device 10 of the second embodiment. In the description of the second embodiment and the subsequent embodiments, the same or similar members as or to those of the first embodiment may be denoted by the same reference numerals in the drawings, and the description thereof may be omitted.

  The snow removal device 10 according to the second embodiment differs from the first embodiment in that a blocking member 61 is further provided in addition to the shutter 14. Here, in the first embodiment, as described above, snow removal is performed when rotating the shutter 14 in a predetermined direction (hereinafter, forward rotation), and thereafter, the shutter 14 is rotated in the opposite direction (hereinafter, reverse rotation) You need to At the time of reverse rotation, the water jetted by the water jet unit 12 is jetted to the railcar 100 through the opening 15. The blocking member 61 is provided in consideration of the possibility that the water jetted at the time of reverse rotation may be applied to the electric device or the like.

  The blocking member 61 is a semi-cylindrical member similar to the shutter 14, and is disposed inside the shutter 14. In addition, openings 62 are formed in the blocking member 61 at the same intervals as the arrangement intervals of the water injection units 12. Further, the blocking member 61 is configured to be slidable in the rotational axis direction (the vehicle left-right direction) by an actuator (not shown). The blocking member 61 performs the slide to position the opening 62 above the water injection unit 12 to enable water injection to the railway vehicle 100 (upper side in FIG. 9), and the water injection A state in which water can not be jetted to the railway vehicle 100 without positioning the opening 62 above the portion 12 (the lower side in FIG. 9) can be realized.

  Therefore, at the time of normal rotation of the shutter 14 (that is, a period during which snow removal is performed), the blocking member 61 can remove the snow by positioning the opening 62 above the water jet unit 12. On the other hand, at the time of reverse rotation of the shutter 14 (that is, a period for preparing for the next snow removal), the blocking member 61 does not position the opening 62 above the water jet unit 12 to inject water to the railway vehicle 100 I will not. The blocking member 61 may be disposed outside the shutter 14.

  Next, a third embodiment will be described with reference to FIG. FIG. 10 is an explanatory view showing a state in which the shutoff state and the injection state are switched by the rotation of the shutter included in the snow removal device 10 of the third embodiment.

  In the first and second embodiments, snow removal is performed at the time of forward rotation, and preparation for snow removal is performed at the time of reverse rotation. On the other hand, in the third embodiment, snow removal can be continued only by rotating the shutter 14 in the same direction. That is, in the shutter 14 of the third embodiment, the water jet unit 12 is covered by the shutter 14 in a cross section cut by a plane perpendicular to the rotation axis direction. Specifically, the shutter 14 of the third embodiment is not a half cylinder but a cylinder. With this configuration, the state transitions as in the first injection timing, the shutoff state, the second injection timing, the shutoff state, the first injection timing,... Simply by rotating the shutter 14 in one direction. Therefore, snow removal of a plurality of railway cars 100 can be performed, for example, without reversing.

  Next, a fourth embodiment will be described with reference to FIG. FIG. 11 is an explanatory view showing a flow of snow removal using the snow removal device 10 of the fourth embodiment.

  The first to third embodiments are configured to dispose the water injection unit 12 at only one place in the vehicle longitudinal direction. Therefore, the railway vehicle 100 is de-snowed once. Instead of this, in the fourth embodiment, the water injection units 12 are arranged at two places in the vehicle longitudinal direction. In the snow removal device 10, the upstream valve 71 switches whether the high pressure pump 11 supplies water to the upstream water injection unit 12 (“open” or “closed”), and the high pressure pump 11 on the downstream side. And a downstream valve 72 for switching whether to supply water. In the present embodiment, only one of the upstream valve 71 and the downstream valve 72 is opened.

  Further, in the fourth embodiment, snow removal is performed only on the first two rail cars 100 among the rail cars 100 in one formation. Specifically, the controller 18 first “opens” the upstream valve 71 and “closes” the downstream valve 72. Thereby, the high pressure pump 11 supplies water only to the water injection unit 12 on the upstream side. Thereby, the snow removal device 10 removes snow from the first rail car 100 by the water injection unit 12 on the upstream side (upper side in FIG. 11). Next, snow removal of the second railway car 100 is performed by the water injection unit 12 on the upstream side (center in FIG. 11).

  The control device 18 "closes" the upstream valve 71 and "opens" the downstream valve 72 after snow removal of the second railway car 100 is completed. Thereby, the high pressure pump 11 supplies water only to the water injection unit 12 on the downstream side. Thereby, the snow removal device 10 removes snow from the first rail car 100 by the water injection unit 12 on the downstream side (the lower side in FIG. 11). Finally, the water jet unit 12 on the downstream side removes snow from the second railway car 100.

  Since snow removal can be performed twice for each of the first and second rail vehicles 100 by one high-pressure pump 11 by performing the snow removal by the above method, snow deposition can be more reliably removed. Also, the expensive high pressure pump 11 can be used efficiently. In addition, in the structure of 4th Embodiment, it is not assumed that snow removal is simultaneously performed by the water injection part 12 of the upstream and downstream based on the relationship of the output of a high pressure pump. Therefore, after snow removal of the second car is finished, the output destination of the high pressure pump 11 is switched from the water injection unit 12 on the upstream side to the water injection unit 12 on the downstream side. Therefore, it is necessary to arrange the upstream side water injection part 12 and the downstream side water injection part 12 apart by at least the length of two of the railway vehicle 100. Assuming that the snow removal is performed twice only for the first car of the rail vehicle 100 (no snow removal is performed for the other rail vehicles 100), the upstream side water injection unit 12 and the downstream side water injection unit 12 It is sufficient if at least the length of the railway vehicle 100 is spaced apart.

  In the fourth embodiment, two water injection units 12 are disposed in the vehicle front-rear direction, but three or more water injection units 12 may be disposed.

  As described above, the snow removal device 10 of the above-described embodiment includes the high pressure pump 11, the water injection unit 12, the shutter 14, the shutter drive motor 17, and the control device 18. The direction of the injection port 13 is fixed, and the water injection unit 12 injects the water delivered by the high-pressure pump 11 from the injection port 13 toward the lower part of the traveling railway vehicle 100. The shutter 14 covers the injection port 13 of the water injection unit 12 and an opening 15 is formed. The shutter drive motor 17 rotationally drives the shutter 14. The controller 18 controls the shutter drive motor 17 so that the water jetted by the water jet unit 12 is blocked by the shutter 14, and the water jetted by the water jet unit 12 flows through the opening 15 to the railway vehicle It is possible to switch between the injection state to be injected to 100.

  Thereby, the presence or absence of water injection can be switched at high speed by rotationally driving the shutter 14 and switching between the blocking state and the jetting state. Therefore, while preventing the water from being jetted to the unnecessary part of the lower part of the railway vehicle 100 while traveling, it is possible to jet the water to the necessary part to remove the adhered matter (snowfall).

  Moreover, in the snow removal apparatus 10 of the said embodiment, the cross section which cut the shutter 14 in the plane perpendicular | vertical to a rotating shaft direction is circular (3rd Embodiment) or circular arc shape (1st and 2nd embodiment).

  As a result, the rotational path of the shutter 14 is unlikely to widen with the rotation, so the space for arranging the shutter 14 can be reduced. Further, in at least the third embodiment, the water jet unit 12 (12a) jets water so as to pass through the rotation axis of the shutter 14, so that the water jet unit 12 to the shutter 14 can be operated regardless of the rotation phase of the shutter 14. The distance can be made constant.

  Further, in the snow removal device 10 of the above-described embodiment, the shutter 14 is provided with a plurality of openings 15 for one water injection unit 12.

  As a result, since water can be jetted a plurality of times only by rotating the shutter 14 in one direction, deposits on various portions of the vehicle can be removed.

  Further, in the water injection unit 12 of the snow removal device 10 of the above embodiment, the water injection unit 12 (12a) whose injection port 13 is directed upward in the vertical direction and the injection port 13 are inclined in the vehicle longitudinal direction At least any one (in detail, all) of the water injection part 12 (12b) and the water injection part 12 (12c) in which the injection port 13 is inclined in the lateral direction of the vehicle with respect to the upper side in the vertical direction included.

  In this way, water can be jetted in various directions in consideration of the shape of the railcar 100, the predicted snowfall location, and the electrical device arrangement location.

  Moreover, in the snow removal apparatus 10 of the said embodiment, the water injection part 12 is adjacently arranged in multiple numbers. The water injection unit 12 is provided with a partition unit 16 disposed between the water injection units 12 so as to prevent water blocked by the shutter 14 from being applied to another water injection unit 12.

  As a result, the water jetted by one of the water jet units 12 is not applied to the other water jet unit 12 via the shutter 14, so water can be jetted from the other water jet unit 12 in an appropriate direction and output.

  Further, in the snow removal device 10 of the above embodiment, the water jetted by the water jet unit 12 is not jetted to the outside, at least in a state where the jet opening 13 of the water jet unit 12 and the opening 15 of the shutter 14 are aligned. And a blocking member 61 for blocking. In a state where the shutter 14 is rotating (forward rotation) in one direction, the blocking member 61 jets the water jetted by the jetting unit without blocking the water. When the shutter 14 is rotating in the other direction (reverse rotation), the blocking member 61 blocks the water jetted by the jetting unit.

  As a result, it is possible to remove snow on the railway vehicle 100 while the shutter 14 is rotating in one direction, and to return the rotational phase of the shutter 14 when the shutter 14 is rotating in the other direction.

  Further, in the snow removal device 10 of the third embodiment, the shutter 14 is cylindrical. As the shutter 14 continues to rotate in one direction, snow deposition on the plurality of railway vehicles 100 is continuously removed.

  Thereby, it is possible to continuously remove the snowfall of the plurality of railcars 100 without reversing the shutter 14.

  Further, in the snow removal device 10 of the above embodiment, the control device 18 changes the rotational speed of the shutter 14 in accordance with the speed of the railcar 100.

  Thus, it is possible to more reliably prevent water from being jetted to unnecessary portions of the lower portion of the railway vehicle 100 in operation.

  In the snow removal device 10 of the above embodiment, the control device 18 starts driving the high-pressure pump 11 or the high-pressure pump according to the detection result of the first vehicle detection sensor 31 that detects that the railcar 100 approaches. The output of the pump 11 is increased.

  Thus, the output of the high-pressure pump 11 can reach the target value before the vehicle passes through the water injection unit 12.

  Moreover, the snow removal apparatus 10 of the said embodiment is provided with the water storage part 20 which collect | recovers and stores the water which the water injection part 12 injected. The water stored in the water storage unit 20 is injected again from the water injection unit 12.

  This can significantly reduce the amount of water used.

  Further, in the snow removal device 10 according to the fourth embodiment, at least two water injection units 12 which are disposed apart from each other in the traveling direction of the rail vehicle 100 are connected to the high pressure pump 11. After the snowfall of the railcar 100 is removed by the water injection unit 12 on the upstream side, the snowfall is removed by the water injection unit 12 on the downstream side in the traveling direction of the railcar 100 with respect to the same railcar 100.

  Thereby, it is possible to remove snow deposition at a plurality of positions with respect to the same railway vehicle 100 while suppressing the number and output of the high pressure pumps 11.

  The preferred embodiment of the present invention has been described above, but the above-described configuration can be modified, for example, as follows.

  In the said embodiment, although the water injection part 12 is arranged side by side in a vehicle left-right direction, it may be arranged side by side in a vehicle front-back direction. In the fourth embodiment, the same high-pressure pump 11 is connected to the water injection unit 12 on the upstream side and the water injection unit 12 on the downstream side in the traveling direction, but individual high-pressure pumps 11 may be connected. In this case, although the apparatus cost is increased, snow removal can be performed on the railcar 100 a plurality of times without separating the positions of the water injection units 12 from each other.

  In the embodiment described above, the water injection units 12 arranged side by side are collectively covered by one shutter 14, but the water injection units 12 arranged side by side may be covered by a plurality of shutters 14. In this case, the plurality of shutters 14 may be configured to rotate integrally or may be configured to rotate individually. The shutter 14 is not limited to a cylinder or a semi-cylinder, but may have a rectangular or polygonal cross section cut by a plane perpendicular to the rotation axis direction.

  In the said embodiment, although it is the structure which collect | recovers the water injected to the water injection part 12, and uses it again, the structure for reusing the injected water can also be abbreviate | omitted.

  The vehicle speed of the railcar 100 may be detected by transmitting an electromagnetic wave or a laser wave toward the railcar 100 and analyzing its reflected wave. Further, it may communicate with the railway vehicle 100 and receive the vehicle speed from the railway vehicle 100.

  In the above embodiment, the snow removal device 10 is disposed on the outer side or the lower side of the rail 51 in the left-right direction of the rail, but at least a part of the snow removal device 10 is elevated You may arrange below.

  The features described in the above embodiments can be combined as appropriate. For example, the blocking member 61 described in the second embodiment can also be used in the fourth embodiment.

  In the above-described embodiment, snow deposition has been described as an example of the deposit, but the present invention can also be applied to an apparatus for removing another deposit (for example, mud). Moreover, in the said embodiment, although the rail vehicle 100 was mentioned and demonstrated as an example of a vehicle, this invention is applicable also to the apparatus which removes the deposit | attachment of another vehicle (for example, a large sized track).
