Description

Technical Field

[0001] The present invention relates to a method, apparatus, and system including the device for automatically connecting a device to a water supply unit. Background Technology

[0002] According to existing technology, connection systems for irrigation units are known. For example, there is a so-called Gardena insert connection system in which fluid transmission line connection can be achieved by inserting two connectors. One of the two connectors forming the line connection includes a connector joint pointing away from the base in the flow direction, which surrounds the outlet channel and is closed by a connector sleeve of the second connector. WO 2010 / 127815 A1 discloses a connector having a body and a connector joint oriented away from the body in a predetermined flow direction. The connector joint surrounds an outlet pipe having a longitudinal axis and has a sealing body disposed upstream of the connector joint within the body. The sealing body prevents water from flowing into the outlet pipe in a blocked position by a blocking seal, and when the connector sleeve is inserted into the connector joint in the insertion direction via the connection structure, the sealing body can be displaced from the blocked position to a through position against the flow direction. Upstream of the coupling, the body widens radially in the form of an annular surface extending transversely to the insertion direction, and the coupling structure includes at least one coupling element that passes through an orifice oriented in the insertion direction in a sealing manner in the annular surface, and is displaceable in the insertion direction and associated with the displacement of the sealing body. In the blocked position of the sealing body, the coupling element protrudes beyond the annular surface. When the coupling sleeve is inserted, the coupling element can be further inserted into the body through the coupling sleeve. Therefore, the coupling of WO 2010 / 127815 A1 includes a valve that opens when the coupling is engaged with the complementary coupling sleeve.

[0003] EP 3 479 682 A1 discloses a self-propelled irrigation device for irrigating an area, comprising: a plurality of wheels; a drive unit for driving at least one of the wheels; an accumulator for driving the drive unit; a water tank; a pump in fluid communication with the water tank; at least one nozzle connected to the pump for discharging water into the environment; and a control system for controlling the movement of the irrigation device and / or the delivery of water, wherein a light sensor for detecting light intensity, particularly intensity of solar radiation, is provided. A docking station for filling the water tank is also disclosed. If the self-propelled irrigation device is properly docked and the nozzle is correctly positioned above the filling port, a filling step is initiated, wherein the nozzle of the water supply unit opens and water is filled into the opening of the water tank in a free-jet manner from the nozzle. This free-jet filling always carries the risk of water overflow when the self-propelled irrigation device is tilted in its operating position, and the required open water tank also presents a risk of water overflow.

[0004] WO 2016 / 202290 A1 discloses an intelligent lawn care system. This intelligent lawn care system includes a robot and a docking base. The docking base is provided with a charging pin for charging the robot and a water supply unit, which includes a short water supply pipe for insertion into the robot's water inlet pipe. When the robot is correctly positioned and a contact switch is activated, a valve opens and water can fill the robot's water tank.

[0005] CN 109 566 065 A discloses another intelligent lawn care system, which includes a robot and a base station. The base station is equipped with an outlet for supplying water to a water tank in the robot. The system also includes a valve that opens when the control module confirms that the robot is in the filling position. Water connection can be achieved by inserting into either the inlet or outlet portion.

[0006] CN 108 720744 A discloses a cleaning robot with a base station. The base station is equipped with an inlet and an outlet for injecting water into a washing tank within the docked robot body and pumping wastewater from a wastewater tank within the robot body. The system features sophisticated feedback, which is necessary to initiate the filling process. Summary of the Invention

[0093] The invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments are illustrated. However, the invention should not be construed as limited to the embodiments set forth herein. Throughout the following description, similar reference numerals have been used to denote similar elements, portions, items, or features, where applicable.

[0094] Figure 1 and Figure 2An irrigation robot 300 is shown. The irrigation robot is a self-propelled device having a body 301 and wheels 302. Specifically, the irrigation robot 300 is provided with two larger drive wheels 302 and two smaller auxiliary wheels for driving on the ground 310. However, different wheel configurations are also possible. The irrigation robot 300 is configured as a device 2, which has a first connecting device 100 for connection with a water supply unit 3. The first connecting device 100 is located at the rear of the irrigation robot 300; however, the first connecting device 100 can also be placed on the opposite side of the irrigation robot. The device 2 is provided with a sleeve having a vertical longitudinal axis. The water supply unit is provided with a ground slot S having a body 401 and a water inlet 400. The water inlet 400 is placed underground (i.e., below the ground 310) for connection via an underground water pipeline.

[0095] Figure 3 to Figure 14 The first implementation of the system is described. (Figures 3 to...) Figure 14 The connection and disconnection of device 2 and water supply unit 3 are shown. Device 2 is provided with a first connection device 100 having a central pipe, and water supply unit 3 is provided with a second connection device 200 having a central pipe and a valve for opening and closing the pipe.

[0096] As shown in Figure 3 to Figure 5a , 5b The first position shown illustrates a first connecting device 100 and a second connecting device 200 that are a certain distance apart from each other. Therefore, the first position is either the start or end position of the method.

[0097] like Figures 6 to 8 The second position shown illustrates the first coupling device 100 and the second coupling device 200 in an engaged position; however, a fluid connection is not yet provided. Figures 9 to 11 The third position shown illustrates the first coupling device 100 and the second coupling device 200 in an engaged and fluidly connected state.

[0098] like Figures 12 to 14 The fourth position shown illustrates the first coupling device 100 and the second coupling device 200 after the fluid connection has been closed and the coupling device has been disengaged.

[0099] According to step S1.1, by automatically bringing device 2 closer to the position of the second connecting device 200, the first connecting device 100 approaches the second connecting device 200, thereby reaching the first position. In Figure 3, the first connecting device 100 and the second connecting device 200 of system 1 are aligned. The first connecting device 100 is provided with a fixed sleeve 110 and a gear shaft 150 for moving the fixed sleeve 110. Specifically, the central pipes 105 and 205 are aligned with each other.

[0100] The first connecting device 100 of device 2 is provided with a fixed sleeve 110 and a release sleeve 152. The fixed sleeve 110 and the release sleeve 152 are arranged concentrically around the central pipe 105. The fixed sleeve 110 and the release sleeve 152 are located on the first side of the attachment member 154, forming a covering member of the irrigation device. On the other side of the attachment member 154, there is a motor 160 to drive a pinion 162. The pinion 162 engages a gear 164 connected to the main shaft 166 of the gear shaft 150. The main shaft 166 engages with the fixed sleeve 110 and the release sleeve 152 for advancing and retracting the sleeves. In the embodiment of FIG3, an optional clamping sleeve 130 is also shown, which is arranged around the main shaft above the fixed sleeve and the release sleeve 152.

[0101] The water supply unit 3 is equipped with a second connecting device 200 having a connector 202 and a central pipe 205. As shown in the figure, the water supply unit can be configured as a groundwater slot S with an underground water inlet. However, the water supply unit 3 can be arranged in different designs and can be placed above ground.

[0102] The connector 202 is provided with a mating surface 204 and may be provided with a sealing element 203 as a sealing ring. Furthermore, the second connecting device 200 is provided with a valve opening member 244 for opening or closing a valve inside the second connecting device 200. The valve 240 is provided with a sealing cone for opening and closing the central conduit 205. The valve opening member may be arranged on a flange surface 206 extending around the connector 202. In the illustrated example, the valve opening member 244 is configured to mechanically open the pin of the valve 240.

[0103] At the end of the first connecting device 100 facing the water supply section 3, a connecting claw 118 is also provided for engaging with the engaging surface 204 of the connector 202, such as... Figure 5a As shown in the diagram, the engaging claw 118 is connected to the release sleeve 152. In this embodiment, a second engaging claw 119 is provided. The second engaging claw 119 is connected to the retaining sleeve 110 and can engage with the release sleeve 152. Both the engaging claw 118 and the second engaging claw 119 are spring-loaded, so that they remain in or return to the non-engaged position when not secured. The front side of the release sleeve 152 is provided with an annular valve opening element 146. Figure 5a A gasket 132 is provided around the central conduit 105. The gasket 132 can terminate directly with the central conduit 105 or can be... Figure 5b The protrusion shown extends beyond the central pipe.

[0104] According to step S1.2, in order to connect the first connecting device to the second connecting device, the connector 202 of the second connecting device 200 is inserted into the sleeve of another first connecting device. In this embodiment, the connector 202 does not move, but the fixed sleeve 110 and the release sleeve 152 are driven by the gear shaft 150 (particularly by the spindle 166 driven by the motor 160). The spindle 166 functionally engages with the release sleeve 152, which in turn connects to the fixed sleeve 110 via the second engaging claw 119.

[0105] When the retaining sleeve 110 and the releasing sleeve 152 are driven on the connector, the engaging claw 118 moves along the outer surface of the connector 202 and engages with the engaging surface 204 around the connector 202. Therefore, according to step S1.3, the engaging device 112 of the first connecting device 100, including the engaging claw 118, engages with the engaging surface 204 of the other second connecting device 200. The state after engagement is as follows... Figures 6 to 8 As shown in the diagram, the sealing cone 242 of valve 240 is in the closed state, which closes the central pipe 205 of the second connecting device 200.

[0106] Next, open the valve according to step S1.4. The open state is as follows: Figures 9 to 12 As shown in the image.

[0107] The release sleeve 152 moves further toward the second coupling device 200. A valve opening element 146 is formed on the front side of the release sleeve 152, which presses against the valve opening member 244 located at the second coupling device 200. As shown in the cross-sectional view, the sealing cone 242 of the valve 240 is pushed downward to open the valve and establish a fluid connection between the first coupling device 100 and the second coupling device 200. Furthermore, the retaining sleeve 110 no longer engages with the release sleeve 152, and the second engagement claw 119 disengages.

[0108] Figures 12 to 14 The separation begins. The release sleeve 152 moves backward so that it no longer pushes against the valve opening member 244, and the valve 240 closes again through the sealing cone. The second engagement claw 119 engages with the retaining sleeve 110 again.

[0109] To return to Figure 3 Figure 5a , 5b In the state shown, the retaining sleeve 110 retracts a distance by contracting the releasing sleeve 152, causing the engaging claw 118 to disengage from the engaging surface 204. Therefore, by moving the retaining sleeve 110, the releasing sleeve 152, and the spindle 166 upward together, the retaining sleeve 110 and the releasing sleeve 152 can now retract from the joint 202, and the first connecting device 100 and the second connecting device 200 can be brought to a position away from each other.

[0110] Figure 15 An irrigation robot 300 according to a second embodiment is shown. This irrigation robot is a self-propelled device having a body 301 and wheels 302. Specifically, the irrigation robot 300 is provided with two larger drive wheels and two smaller auxiliary wheels. However, different wheel configurations are also possible. The irrigation robot 300 is provided with a device 2 having a first connecting device 100 for connecting to a water supply unit 3 having a second connecting device 200. The device 2 is located at the front of the irrigation robot 300. However, this device can also be located on the opposite side. The device 2 is provided with a sleeve having a horizontal longitudinal axis. The water supply unit 3 is provided with a body 401 that fixes the position and orientation of the second connecting device 200. Specifically, the first connecting device 100 and the second connecting device 200 have the same height h above the ground. The body 401 is specifically designed as an independent device on the ground. A water inlet 400 is provided on the side opposite to the second connecting device 200. The height of the water inlet 400 is not limited to the configuration shown.

[0113] Figure 18 and Figure 19 System 1 is shown, in which the connector has been inserted and the coupling devices are engaged with each other.

[0114] Figure 20 and Figure 21 System 1, shown with the valve open, allows the inlet to be fluidly connected to the device.

[0115] Figure 22 and Figure 23 The system 1 is shown when the first connecting device 100 is disconnected from the second connecting device 200. The valve is closed.

[0116] By bringing the device 2 close to the position of the second connecting device 200, the first connecting device 100 approaches the second connecting device 200. Figure 16 As shown Figure 17The system shown is a cross-sectional view. The first connecting device 100 is provided with a central conduit 105, which is surrounded by a fixed sleeve 110. In this embodiment, no separate release sleeve is provided, so the fixed sleeve is a single sleeve 170. An unengaged engagement claw 118 is shown. The engagement claw 118 is spring-loaded, so that the engagement claw remains in or returns to the unengaged position when not secured. The engagement claw 118 is connected to the fixed sleeve 110. The device 2 is also provided with a gear shaft 150 and a motor 160 for controlling the position of the fixed sleeve 110. The gear shaft 150 is dedicated to moving the fixed sleeve 110 toward or away from the attachment member 154 along the longitudinal axis L. The second connecting device 200 is provided with: a connector having a central conduit 205; and a valve 240 having a sealing cone 242 for closing the central conduit 205 of the second connecting device 200. In the end region, the connector 202 is provided with a sealing element 203. The connector 202 is also provided with an engagement surface 204.

[0117] Figure 18 and Figure 19 The next step of the connection is shown. Connector 202 is inserted into the sleeve of another first connecting device 100 (particularly the gasket 132, coaxially arranged with the central conduit inside the fixed sleeve 110) and the fixed sleeve 110. The engaging device 112 of the first connecting device 100, including the engaging claw 118, engages with the engaging surface 204 of the second connecting device 200. Valve 240 remains closed. Specifically, device 2 is approached as a complete device, but alternatively, the gear shaft can drive the fixed sleeve toward the second connecting device 200. Therefore, Figure 18 and Figure 19 The position after steps S1.2 and S1.3 are completed is shown.

[0118] In the next step S1.4), the valve 240 located inside the second connecting device 200 is opened by the front portion of the fixed sleeve 110, which is arranged together with the first connecting device 100 on an annular surface, and the valve opening element 146 presses against the valve opening member 244 of the second connecting device 200. The valve opening member may be a pin located at the flange surface 206. Therefore, by bringing the valve opening element 246 (here, the front surface of the fixed sleeve) into contact with the flange surface 206, the valve opening member 244 is actuated. Figure 20 and Figure 21 The fluid connection described in the text.

[0119] The following figures Figure 22 and Figure 23Separation is now shown. In the next step, the valve 240, located inside the second coupling device 200, is closed by releasing the valve opening element, which is arranged together with the first coupling device, from the valve opening member 244 of the second coupling device 200. The retaining sleeve 110 is retracted via the gear shaft 150 and thus no longer presses against the valve opening member 246.

[0120] The engaging device 112 (here, the engaging claw 118) of the first connecting device 100 disengages from the engaging surface 204 of the second connecting device 200. The retaining sleeve 110, in its retracted state, no longer holds the engaging claw 118 to (particularly presses against) the engaging surface 204. The retaining sleeve can now be fully retracted from the joint of the second connecting device, and the distance between the first and second connecting devices can now be increased by removing the device 2.

[0121] Figures 24 to 31 A third embodiment of system 1 is shown. In contrast to the embodiments described above, it can be designed to be... Figure 15 In this embodiment, the similar irrigation robot device 2 is configured as a convex connector and is provided with a joint 102.

[0122] Figure 24 and Figure 25 The system 1 is shown in a first unconnected state, wherein the first connecting device and the second connecting device are aligned using their respective pipes.

[0123] Figure 26 and Figure 27 System 1 is shown, in which the connector has been inserted and the coupling devices are engaged with each other.

[0124] Figure 28 and Figure 29 System 1, shown with the valve open, allows the inlet to be fluidly connected to the device.

[0125] Figure 30 and Figure 31 System 1, with the valve open, is shown, allowing the inlet to be fluidly connected to the device, but with an alternative release element instead of a sleeve.

[0126] Figure 24 and Figure 25 The device 2, which is close to the water supply unit 3, is shown.

[0127] The water supply unit 3 is provided with a body 401, which fixes the position and orientation of the second connecting device 200. Specifically, the first connecting device 100 and the second connecting device 200 have the same height h above the ground. The body 401 is specifically designed as a stand-alone device on the ground. The water inlet 400 is located on the side opposite to the second connecting device 200. The height of the water inlet 400 is not limited to the configuration shown.

[0128] Device 2 is equipped with a release sleeve 152. Water supply unit 3 is equipped with a fixing sleeve 210. Figure 26 and Figure 27 The diagram shows the connector 102 of the first connecting device 100 inserted into the retaining sleeve 210 of the second connecting device 200. This insertion is actuated by bringing the device 2 closer to the water supply section 3. The valve 240 of the second connecting device 200 is similar to the valve shown in the previous figures. However, in this embodiment, the valve opening element 146 is the end of the valve cone that pushes the connector 102 open. Therefore, the valve 240 opens once the connector 102 is fully inserted. In this embodiment, the engagement claw 218 is provided together with the second connecting device 200 at the water supply section 3. When the connector 102 is fully inserted, the engagement claw 218 engages with the engagement surface 104. The connector 102 is also provided with a sealing element 103.

[0129] Figure 28 and Figure 29 The separation of the first connecting device 100 and the second connecting device 200 is shown. The release sleeve 152 is driven toward the second connecting device 200 via the gear shaft 150, that is, driven out from the outer sleeve 134 surrounding the release sleeve 152 and connected to the attachment member 154. A cross-sectional view of the device shows the central pipe 105 surrounded by the release sleeve 152. The connector 102 is provided with an engagement surface 104. The second connecting device 200 is provided with the central pipe 205, a retaining sleeve 210, and an engagement claw 218. The engagement claw 218 is spring-loaded, allowing it to remain in or return to a non-engaged position when not secured. The release sleeve 152 can push the retaining sleeve 210 toward the water supply section 3. When the retaining sleeve 210 is pushed back from the fixed position to the release position, the engagement claw 218 disengages, and by moving the device away from the water supply section, the connector can retract and the device 2 and the water supply section can be separated.

[0130] Figure 30 and Figure 31 As shown Figure 28 and Figure 29 An alternative embodiment of the illustrated embodiment is provided. The first coupling device 100 is provided with a release element 153, which is not a sleeve and replaces the release sleeve 152. The release element 153 is arranged outside the outer sleeve 134 and extends along the outer sleeve 134. However, the function of the release element 153 remains unchanged.
