[0028] In artificial fountain devices, the water spraying devices are mostly unidirectional 360° rotating and spraying water. However, when the water spraying device rotates multiple times in one direction, the external cable will be entangled outside the water spraying device, which will not only cause the cable to break, but also cause damage to the water spraying device.
[0029] See also Figure 1-Figure 4 In order to solve the problem that the cable 400 is easily entangled in the existing artificial fountain device, the present application provides an anti-entanglement fountain device, which includes a first driving part, a second driving part, a nozzle head 300 and a cable 400, and the first driving part is electrically connected to the second driving part through the cable 400.
[0030] It should be noted that, in this embodiment, the first drive unit and the second drive unit are connected to the power supply and the controller via the cable 400. Of course, it is understandable that the controller may also be an independent structure respectively provided in the first drive unit and the second drive unit, in which case the cable 400 may only play the role of power transmission.
[0031] like Figure 1-Figure 4 As shown, the second driving unit is arranged at the output end of the first driving unit, and the nozzle head 300 is arranged at the output end of the second driving unit. The first driving unit can drive the second driving unit and the nozzle head 300 to rotate around the first axial direction, and the second driving unit can drive the nozzle head 300 to rotate around the second axial direction.
[0032] It can be understood that the spray head 300 can be driven by a two-stage driving mechanism of a first driving unit and a second driving unit.
[0033] It should be noted that, in order to increase the spraying angle of the spray head 300 in three-dimensional directions, in one embodiment, the first axial direction and the second axial direction are arranged at an angle.
[0034] Preferably, the first axial direction is perpendicular to the second axial direction. In this case, the first axle 140 is arranged perpendicular to the second axle 240 .
[0035] Specifically, in one embodiment, if Figure 1-Figure 4 As shown, the first driving part includes a first motor 110, a first worm 120, a first worm wheel 130 and a first axle 140. The first worm 120 is arranged at the output end of the first motor 110, and the first axle 140 is fixedly connected to the first worm wheel 130 and is coaxially arranged with the first worm wheel 130. The first motor 110 is connected to the second driving part through the first worm 120, the first worm wheel 130 and the first axle 140 in sequence to drive the second driving part and the nozzle head 300 to rotate around the first axial direction.
[0036] By providing the reduction structure of the first worm 120 and the first worm wheel 130 , the transmission ratio and the transmission stability of the first driving part can be improved.
[0037] However, the present invention is not limited thereto. In other embodiments, the first driving unit may also output torque via a reduction structure such as a gear reducer.
[0038] Furthermore, in one embodiment, the first axle 140 is fixedly disposed in the first worm gear 130 . Specifically, the first axle 140 can be welded to the first worm gear 130 , or can be clamped to the first worm gear 130 .
[0039] In order to prevent water from entering the first motor 110 , in one embodiment, a first sealing cover (not shown) is provided on the outer side of the first motor 110 , and the space between the first motor 110 and the first sealing cover is filled with epoxy resin.
[0040] In one embodiment, if Figure 1-Figure 4 As shown, the first driving part also includes a first shell 150, and the first worm 120, the first worm wheel 130 and the first axle 140 are all installed in the first shell 150. It should be noted that due to the large size of the first motor 110, the first motor 110 is fixedly installed on the outside of the first shell 150, but it is not limited to this. In other embodiments, the first motor 110 can also be set in the first shell 150.
[0041] It should be noted that, in order to facilitate the assembly of the first worm 120, the first worm wheel 130 and the first axle 140, in one embodiment, the first housing 150 can be formed by assembling multiple parts. Specifically, the first housing 150 is formed by welding multiple parts or screwing them together with fasteners.
[0042] Of course, in order to improve the sealing performance of the first shell 150, in another embodiment, the first shell 150 can also be integrally formed.
[0043] In one embodiment, if Figure 4 As shown, the first driving unit also includes a first bearing 160 , and one or more first bearings 160 are respectively sleeved on the outer peripheral side of the first axle 140 along the axial direction of the first axle 140 , so that the first axle 140 can be rotatably connected to the first shell 150 through the first bearing 160 .
[0044] In this way, the rotation stability of the first axle 140 can be increased, and the first axle 140 can be prevented from being eccentric.
[0045] In one embodiment, the anti-entanglement fountain device also includes a torque limiter (not shown), which is arranged at the output end of the first motor 110, and the first motor 110 is connected to the first worm 120 through the torque limiter. When the output torque of the first motor 110 applied to the torque limiter is greater than a first preset value, the torque limiter can slip to avoid overloading of the first motor 110.
[0046] In another embodiment, the first axle 140 is connected to the second driving unit via a torque limiter. That is, there are various situations for setting the torque limiter, all of which can prevent the first motor 110 from overloading.
[0047] In one embodiment, if Figure 1-Figure 4 As shown, the second driving part includes a second motor 210, a second worm (not shown), a second worm wheel 230 and a second axle 240. The second worm is arranged at the output end of the second motor 210, and the second axle 240 is fixedly connected to the second worm wheel 230 and is coaxially arranged with the second worm wheel 230. The second motor 210 is connected to the nozzle head 300 through the second worm, the second worm wheel 230 and the second axle 240 in sequence to drive the nozzle head 300 to rotate around the second axial direction.
[0048] By providing the speed reduction structure of the second worm and the second worm wheel 230 , the transmission ratio and the transmission stability of the second driving part can be improved.
[0049] However, the present invention is not limited thereto. In other embodiments, the second driving unit may also output torque via a reduction structure such as a gear reducer.
[0050] In order to prevent water from entering the second motor 210, in one embodiment, Figure 1-Figure 4 As shown, a second sealing cover 280 is sleeved on the outer side of the second motor 210 , and the space between the second motor 210 and the second sealing cover 280 is filled with epoxy resin.
[0051] Furthermore, in one embodiment, the second axle 240 is fixedly disposed through the second worm gear 230 . Specifically, the second axle 240 can be welded to the second worm gear 230 , or can be clamped to the second worm gear 230 .
[0052] Further, in one embodiment, if Figure 1-Figure 4 As shown, the second driving part also includes a second shell 220, and the second worm, the second worm wheel 230 and the second axle 240 are all installed in the second shell 220. It should be noted that due to the large size of the second motor 210, the second motor 210 is fixedly installed on the outside of the second shell 220, but not limited to this. In other embodiments, the second motor 210 can also be set in the second shell 220.
[0053] Furthermore, the second housing 220 is fixedly connected to one end of the first axle 140 away from the first worm gear 130 , so that the first axle 140 can drive the entire second driving unit and the spray head 300 to rotate through the second housing 220 .
[0054] It should be noted that, in order to facilitate the assembly of the second worm, the second worm wheel 230 and the second axle 240, in one embodiment, the second housing 220 can be formed by assembling multiple parts. Specifically, the second housing 220 is formed by welding multiple parts or screwing them together with fasteners.
[0055] Of course, in order to improve the sealing performance of the second shell 220, in another embodiment, the second shell 220 can also be integrally formed.
[0056] Further, in one embodiment, if Figure 1-Figure 3 As shown, the cable 400 connects the first motor 110 and the second motor 210, and the first driving unit further includes a first fixing plate 170, one end of the first fixing plate 170 is connected to the first housing 150, and the other end extends in a direction away from the first housing 150, and the second driving unit further includes a second fixing plate 270, one end of the second fixing plate 270 is connected to the second housing 220, and the other end extends in a direction away from the second housing 220. The cable 400 is disposed outside the first housing 150 and the second housing 220, and one end of the cable 400 is assembled to one end of the first fixing plate 170 away from the first housing 150, and the other end is assembled to one end of the second fixing plate 270 away from the second housing 220.
[0057] It should be noted that the cable 400 disposed between the first fixing plate 170 and the second fixing plate 270 needs to have a sufficient length and should not be in a tight state to prevent the cable 400 from affecting the rotation of the second driving unit.
[0058] In this configuration, the cable 400 is disposed outside the first shell 150 and the second shell 220 , and the distance between the cable 400 and the first shell 150 and the second shell 220 is increased, which facilitates the assembly and maintenance of the cable 400 .
[0059] Furthermore, in one embodiment, if Figure 1-Figure 3 As shown, the first driving unit further includes a blocking column 180 , which is disposed between the first housing 150 and the cable 400 , and is assembled on the first fixing plate 170 .
[0060] In this way, by providing the blocking column 180 , the cable 400 and other sensor wires provided outside the first housing 150 can be prevented from being entangled.
[0061] But not limited to this, in another embodiment, Figure 4As shown, the first axle 140 is provided with a through hole extending along its own axial direction, and the cable 400 is movably inserted into the through hole so that the first axle 140 can provide a certain limit and protection for the cable 400. At this time, the first axle 140 partially extends into the second shell 220, and the cable 400 is partially arranged in the first shell 150 and the second shell 220.
[0062] It should be noted that the cable 400 disposed in the first housing 150 needs to be of sufficient length and should not be in a tight state to prevent the cable 400 from affecting the rotation of the second driving unit.
[0063] In one embodiment, if Figure 4 As shown, the second driving unit also includes a second bearing 250, and one or more second bearings 250 are respectively sleeved on the outer peripheral side of the second axle 240 along the axial direction of the second axle 240, so that the second axle 240 can be rotatably connected to the second shell 220 through the second bearing 250.
[0064] In this way, the rotation stability of the second axle 240 can be increased, and the second axle 240 can be prevented from being eccentric.
[0065] Further, in one embodiment, if Figure 1-Figure 4 As shown, the water inlet 151 of the anti-winding fountain device is arranged on the first shell 150, and the water inlet 151 is connected to the water outlet 310 of the nozzle head 300 through the internal space of the first shell 150 and the second shell 220 in sequence. The second driving part also includes a third bearing 260, and the second shell 220 is rotatably connected to the first shell 150 through the third bearing 260. Specifically, the outer ring of the third bearing 260 is fixedly connected to one of the first shell 150 and the second shell 220, and the inner ring of the third bearing 260 is fixedly connected to the other of the first shell 150 and the second shell 220.
[0066] Such arrangement, on the one hand, improves the connection strength between the first shell 150 and the second shell 220 and increases the rotational stability of the second driving part, and on the other hand, can prevent water from leaking from between the first shell 150 and the second shell 220, that is, improves the connection sealing between the first shell 150 and the second shell 220.
[0067] Similarly, in one embodiment, if Figure 4 As shown, the spray head 300 also includes a fourth bearing 320, and the second shell 220 is rotatably connected to the spray head 300 through the fourth bearing 320. Specifically, the outer ring of the fourth bearing 320 is fixedly connected to one of the spray head 300 and the second shell 220, and the inner ring of the fourth bearing 320 is fixedly connected to the other of the spray head 300 and the second shell 220.
[0068] Furthermore, if Figure 1 and Figure 4 As shown, the first driving part is provided with a first stopper 190, and the second driving part is provided with a second stopper 290 corresponding to the first stopper 190. The first stopper 190 can block and cooperate with the second stopper 290 so that the relative rotation angle of the first driving part and the second driving part is less than 360 degrees.
[0069] Since the first stopper 190 and the second stopper 290 can act as stops on the rotation path of the second drive unit, the second drive unit cannot continuously rotate in one direction around the first drive unit, that is, the maximum rotation angle of the second drive unit is less than 360 degrees. At this time, it is only necessary to perform appropriate redundant design on the cable 400 to satisfy the rotation of the second drive unit relative to the first drive unit, and the cable 400 will not be entangled or twisted on a large scale, thereby effectively avoiding damage to the cable 400 and increasing the service life of the anti-entanglement fountain device.
[0070] Furthermore, in one embodiment, the first stopper 190 is disposed on the outer side of the first shell 150 , and the second stopper 290 is disposed on the outer side of the second shell 220 .
[0071] Specifically, a protrusion is welded or clamped on the outer side of the first shell 150 to form the first stopper 190 .
[0072] A bolt or a screw is installed on the outer side of the second housing 220 to form a second stopper 290 .
[0073] In one embodiment, the anti-entanglement fountain device also includes a controller (not shown), which is electrically connected to the first drive unit and the second drive unit, respectively. When the second stopper 290 stops at one end of the first stopper 190, the controller can control the second drive unit to rotate in the opposite direction (for example, when the second drive unit starts to rotate clockwise, the reverse rotation is counterclockwise) until the second stopper 290 stops at the other end of the first stopper 190, and when the second stopper 290 stops at the other end of the first stopper 190, the controller can control the second drive unit to rotate in the positive direction, and so on and so forth. The controller can cause the second drive unit to reciprocate relative to the first drive unit, and at this time, the cable 400 is more difficult to get entangled.
[0074] Furthermore, in one embodiment, the anti-entanglement fountain device also includes a sensor (not shown), which may be a pressure sensor, and the pressure sensor is disposed on one or both of the first stopper 190 and the second stopper 290 . The sensor may also be a laser ranging sensor, and the laser ranging sensor may be disposed outside the first stopper 190 and the second stopper 290 .
[0075] It should be noted that the spray head 300 can continuously rotate 360 degrees in one direction relative to the second driving part, but is not limited thereto. The spray head 300 can reciprocate relative to the second driving part.
[0076] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0077] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
