Description

[0001] The innovation concerns a mobile irrigation device for irrigating a landscaped area.

[0002] Corresponding irrigation devices for irrigating a landscaped area are basically known from the prior art. For example, it is known to arrange a water reservoir on a vehicle and move it to a destination for irrigating a landscaped area using a vehicle-mounted drive motor. The disadvantage of this is that it requires a high level of equipment and technical complexity, and due to the mass of the vehicle, it usually results in undesirable damage to the surface of the landscaped area. In addition, the power supply for the drive motor and an irrigation pump for conveying the water from the water reservoir to the landscaped area is provided by an on-board energy storage device, e.g., the fuel tank or a traction battery of the vehicle, so that this alone does not allow irrigation of the landscaped area to be carried out independently by the vehicle.

[0003] The innovation is based on the task of specifying an irrigation device for irrigating a landscape area, which is self-sufficient and can be operated and relocated by a single person and without major technical and equipment expenditure.

[0004] The object is achieved by a mobile irrigation device for irrigating a landscape area according to claim 1. The dependent claims relate to possible embodiments of the irrigation device.

[0005] The invention relates to an irrigation device for irrigating a landscaped area, comprising a solar device comprising at least one solar module for solar-assisted generation of electrical energy. The solar module enables a self-sufficient energy supply to the irrigation device, so that, after installation, it can be operated without an energy storage device for supplying energy to a pumping device that delivers the water. The irrigation device described herein and installed at a site can also be operated without the presence of a person.

[0006] The mobile irrigation device further comprises a support device to which the at least one solar module is or can be releasably attached. In a preferred embodiment, the at least one solar module, in particular all solar modules, are mounted on the support device via holding means. Alternatively or additionally, the releasable attachment of the at least one solar module can comprise a clamping block, e.g., a T-clamping block with a handle, e.g., a wing nut or a screw or screw nut provided with a gripping portion, in particular a star-shaped one.

[0007] The support device serves, in particular, to position the at least one solar module securely and in a defined position and / or alignment with the landscaped area or installation area. The at least one solar module is typically a flat body that can be positioned on the installation area at a predefined angle to the horizontal by means of the support device. The support device can be releasably anchored or anchored to a landscaped area via at least one anchoring means. In other words, the anchoring means enables stable attachment of the support device and the at least one solar module releasably attached to the support device. In particular, the anchoring means is designed and dimensioned such that it can withstand any wind loads acting on the irrigation device.

[0008] The irrigation device further comprises a pump device which can be or is supplied with electrical energy by the solar device in order to pump water from an extraction point to a target location for irrigating the landscaped area. The water can be extracted, for example, from a flowing or standing body of water. It is also possible to pump groundwater with the pump device through a well or through a well bore. Preferably, the water can be extracted from a lake or a stream. The pump device can comprise a pump and hoses connected to the pump, wherein a first hose connects a suction connection of the pump to the body of water to be extracted and a second hose connects a pressure side or an outlet connection of the pump to a target location on the landscaped area to be irrigated. It is optionally possible for the suction connection of the pump to be located directly on the, e.g.into the body of water to be pumped. Alternatively, the water leaving the pump's outlet connection can be applied directly to the landscape area to be irrigated.

[0009] The solar device and / or the pump device can comprise at least one control and / or regulating unit. For example, the control and / or regulating unit comprises a controller for the at least one solar module. The control and / or regulating unit can, for example, be arranged in a housing, wherein the housing is arranged on, e.g. in or on, the support device. This housing is preferably arranged on the support device in such a way that, during normal operation of the mobile irrigation device, it is covered on top, in particular completely, by the at least one solar module, so that the solar module ensures protection of the housing of the control and / or regulating unit from direct sunlight and / or direct exposure to rain.

[0010] It is possible that at least two, preferably at least three, particularly preferably at least four, solar modules are attached or can be attached to the support device, wherein a solar module has a size of (a) a maximum of 62500 cm 2 , preferably 40000 cm 2 , particularly preferably 25500 cm 2 , more preferably 15000 cm 2 , most preferably 10000 cm 2 , and / or (b) at least 3600 cm 2 , preferably 5500 cm 2 , particularly preferably 10000 cm 2 , more preferably 14400 cm 2 In a preferred embodiment, the support device carries a solar module having an area of approximately (+ / -10%) 6000 cm 2For example, the at least one solar module has a length and width of a maximum of 250 x 250 cm, preferably 200 x 200 cm, particularly preferably 180 x 160 cm, further preferably 170 x 150 cm, most preferably 140 x 160 cm, furthermore preferably 65 x 90 cm, and / or a minimum of 60 x 60 cm, preferably 65 x 80 cm. The specified sizes of the individual solar modules have the advantage that they are easy to handle by a single person, i.e. can be easily gripped and moved by a person with, for example, two hands. The specified sizes of the individual solar modules also have the advantage that the weight of the solar modules is so low that they can be easily carried by one person. Since the at least one solar module is detachably attached to the carrying device, by loosening the attachment the at least one solar module can be individually gripped and comfortably moved or carried by a person.This supports the advantage that the present mobile irrigation device can be moved by a single person or relocated from a first area of a landscaped area to a second area of a landscaped area. The at least one solar module can, for example, have an output of 20 to 300 W, preferably 40 to 200 W, particularly preferably 60 to 150 W, most preferably 80 to 125 W.

[0011] The solar device can, for example, be detachably connected to the pump device via a power cable. This means that the pump device does not have to be located directly at the installation site of the solar device, but can be arranged at a distance from the solar device thanks to the power cable. The power cable can have a length of at least 1 m, preferably at least 2 m, particularly preferably at least 4 m, further preferably at least 8 m, and most preferably at least 12 m. Alternatively or additionally, the power cable has a properties that are suitable for long-term use in above-ground outdoor areas. For example, the power cable can have a sheath that offers UV radiation protection or exhibits low aging due to exposure to UV radiation. For example, an underground cable and / or a cable of category NYY or NYCWY can be used as the power cable.This allows the irrigation device to operate over extended periods, unaffected by weather conditions, particularly autonomously. The power cable, designed for long-term above-ground outdoor use, can also be generally robust, so that in the event of repeated disassembly and assembly of the mobile irrigation device, no limitations arise due to possible material fatigue of the power cable or other installation influences on the power cable.

[0012] The carrying device can, for example, have a maximum weight of 50 kg, preferably a maximum weight of 30 kg, particularly preferably a maximum weight of 20 kg, further preferably a maximum weight of 15 kg, and most preferably a maximum weight of 10 kg. Thus, the carrying device can be comfortably and safely carried and relocated by a single person, particularly after the at least one solar module carried or carried by the carrying device has been detached from the carrying device.

[0013] The support device can be designed, at least in part, preferably predominantly, and particularly preferably entirely, as a frame comprising struts. The frame-like or truss-like structure of the support device allows it to be constructed in a stable manner while remaining lightweight, thus enabling the support device to reliably secure the at least one solar module to the landscaped area.

[0014] At least two struts of the support device can, for example, be detachably connected to one another or connectable to one another. For example, at least one strut of the support device can be connected to the frame and / or to another strut without tools. This means that the at least one strut can be connected to another component of the frame and / or at least two struts can be connected to one another manually and without the use of a tool. Alternatively or additionally, at least two struts of the support device can be connected to one another or connectable to one another by means of screws. This makes it possible for a first group of connection interfaces of components of the support device to be connected and / or disconnected with the aid of tools, and for a second group of connection interfaces of components of the support device to be connected and / or disconnected without tools.

[0015] Optionally, at least two components, in particular struts, of the support device can be connected or connectable to one another by a connecting means such that, in a separated state or in a state in which the two struts are detached from one another, they are movably connected or connectable to one another via the connecting means. For example, the connecting means is designed to be flexible and / or elastic, so that, in the detached state, the two struts can be arranged parallel and next to one another. In particular, the connecting means can be arranged in an interior space of the at least two struts, each of which is designed as a tubular body. For example, the connecting means is not externally visible when the tubular bodies are plugged together.

[0016] The support device can be made of metal, for example, preferably steel or aluminum. The support device preferably consists of struts made of steel or aluminum.

[0017] The at least one solar module can, for example, be fastened to the support device without tools and / or detachably fastened from the support device without tools. For example, a fastening structure can be provided on the at least one solar module and on the support device, which enables, for example, a plug-in connection. Alternatively or additionally, a fastening mechanism can be provided that enables a latching connection (snap-lock connection) of the at least one solar module to the support device. The fastening mechanism can optionally have an actuating means, by the actuation of which a locking element is or can be transferred into a release position against a pretensioning force (of a pretensioning means) that pretensions it into a closed position.

[0018] In a preferred embodiment, the irrigation device has a clamping unit by means of which a clamping attachment of the at least one solar module to the support device can be carried out. The clamping unit can preferably be transferred tool-free and / or manually from a release position releasing the at least one solar module into a locking position holding or fastening the at least one solar module. For example, at least the transfer of the clamping unit from the release to the locking position and / or the transfer of the clamping unit from the locking to the release position can be carried out tool-free and / or manually. This allows for simple and convenient assembly and / or disassembly of the at least one solar module from the support device. A clamping or force-fitting attachment can be carried out by means of the clamping unit. The clamping unit can, for example, comprise a clamping profile.The clamping unit can have at least one clamping means with a handle or grip. Thus, the clamping means can be designed, for example, as a screw, i.e., as a screw or nut with a gripping area.

[0019] It is possible for the at least one anchoring means to form a component separate from the support device, which penetrates into the landscape area with a penetration section in order to anchor the support device to the landscape area and forms a positive and / or non-positive connection with the support device using a holding section. For example, the holding section on the anchoring means engages around a counter-holding section of the support device. The counter-holding section can preferably come into contact with a section of a component of the support device that faces away from the landscape area, e.g. a strut, or can at least partially engage around this remote section. The counter-holding section on the support device side can, for example, have a horizontal main axis of extension, in particular form a horizontally running strut of the support device. For example, the at least one anchoring means is designed as a peg orA tent peg is designed that penetrates the landscape through a rotating movement (e.g., screwing in) and / or a linear movement (e.g., through an impulse such as a hammer blow). It is possible for the at least one anchoring means to be captively attached to the support structure. For example, at least one anchoring means can be captively connected to the support structure by means of a flexible connecting means.

[0020] For example, the anchoring means comprises a penetration section that penetrates at least partially into the ground. In addition to the penetration section, a through-hole can be arranged or formed that is fastened or fastenable to the support device and rests against the ground or is spaced from the ground, wherein a fastening means is passed through the through-hole and inserted into the ground, in particular hammered or screwed in, so that the fixation of the support device comprises, on the one hand, the penetration sections, and, on the other hand, additionally an anchoring by the penetration of the fastening means (e.g., a peg) into the ground, wherein the fastening means provides further fastening via the positive connection with the through-hole.

[0021] The at least one anchoring means can, for example, form a component of the support device, wherein a penetration section of the anchoring means penetrates into the landscape area to anchor the support device to the landscape area. For example, at least one anchoring means is designed as a rigid component of the support device. This anchoring means can be detachably or permanently fastened to the support device. For example, a section, in particular a section (e.g. strut) of the support device which runs essentially vertically after the support device has been set up as intended, can have a penetration section of the anchoring means at its end facing the landscape area. For this purpose, this end can have a conical or tapered shape so that when the support device is pressed down, the penetration section penetrates into the landscape area. Optionally, a base structure (e.g.Anchoring means designed for the scaffolding of the support device must be attached or capable of being attached to a basic structure of the support device in a tool-assisted manner (e.g. screw connection using a hexagon screw) or detachable without tools (e.g. screw connection using a wing screw) or non-detachable (e.g. adhesive or welded connection).

[0022] The support device can, for example, have at least one footrest section configured to allow a person to place at least one foot on the footrest section, and the person's weight can be at least partially transmitted to the footrest section as a compressive force, so that a compressive force directed toward the landscaped area can be applied to the support device via the footrest section. This allows the support device or a penetration section of an anchoring means arranged or formed on the support device side to comfortably penetrate the landscaped area.In other words, a person can press the underside of the support device against a landscape surface by placing themselves on the footrest section using the person's own weight, in order to achieve a more stable position of the support device on landscape surfaces, in particular on swampy and / or uneven and soft landscape surfaces. If the support device has at least one anchoring means, in particular one rigidly connected to the support device, on its side facing the landscape surface, the anchoring means can penetrate into the landscape surface or the ground by means of the person's own weight, through the support device-supported transfer of the compressive force applied to the footrest section.

[0023] Optionally, the mobile irrigation device can have a radio module by means of which a radio connection to a mobile terminal can be established, wherein control information controlling an operating parameter of the pump device and / or operating state information describing an operating state of the pump device 6 and / or the solar device can be transmitted via the radio module. For example, control information transmitted by a mobile terminal as a radio signal can be received by the radio module and transmitted to the solar device and / or the pump module via a cable and / or wirelessly (e.g., via a radio connection) in order to change or control an operating state of the pump device, in particular its delivery rate. Accordingly, a person at a distance from the mobile irrigation device can receive information from or transmit information to the irrigation device via the radio module on the irrigation device side.The radio module can, for example, be configured to enable data transmission via Bluetooth. For example, the pumping device, in particular the pump of the pumping device, can be controlled via Bluetooth data connection.

[0024] The support device can, for example, be designed to be at least partially foldable and / or pluggable and / or foldable. In particular, at least one strut of the support device can be designed to be foldable and / or pluggable and / or foldable at a connection interface to a second strut to be connected to this strut. Alternatively or additionally, at least one strut of the support device can be arranged or designed to be foldable and / or pluggable and / or foldable on another component of the support device. The foldability and / or pluggability and / or foldability of the support device enables a compact support device when not in use. The pluggability can also enable at least partial separation of components of the support device, making them easier for a single person to handle and move.The collapsibility and / or pluggability and / or folding can preferably be carried out by a single person without the need for tools. A plug-in connection of at least two components of the support device, in particular at least two pluggable struts, can, for example, comprise a clamping fixture and / or a split pin, thus preventing accidental detachment of the two plugged-together components.

[0025] It is possible for the support device to be configured to support or align the at least one solar module at an angle in the range of 25° to 60°, preferably 30° to 50°, particularly preferably 34° to 46°, further preferably at an angle of 35° or 45°, to a mounting surface. For this purpose, the support device can have a solar module receptacle that is aligned with a ground anchor at the aforementioned angles. Preferably, the support device does not have any means for adjusting the angle of incidence of the at least one solar module to the mounting surface. Optionally, the support device has one of the aforementioned angles without this being adjustable to a significant extent (greater than + / - 10°). This allows the weight of the support device to be further reduced because a lockable adjustment mechanism on the support device side is dispensed with.

[0026] The carrying device with the at least one solar module attached thereto, in particular with all solar modules attached to the carrying device during normal operation of the mobile irrigation device, can, for example, have a maximum weight of 70 kg, preferably a maximum of 60 kg, particularly preferably a maximum of 50 kg, particularly preferably a maximum of 40 kg, most preferably a maximum of 35 kg. In other words, the carrying device, together with the at least one solar module mounted thereon, can be comfortably carried as an assembly by a single person after unplugging (disconnecting) the pump device and the cable connecting the pump device to the at least one solar module. This enables a comfortable relocation of the mobile irrigation device by a single person.

[0027] The pumping device can, for example, comprise a pump designed as an eccentric pump. The pump is preferably designed as an eccentric screw pump.

[0028] Alternatively or additionally, the support device and the components fastened thereto, with the exception of the at least one solar module and the anchoring means detachably attachable to the support device, can, for example, have a weight of at least 5 kg, preferably at least 10 kg, particularly preferably at least 13 kg, further preferably at least 15 kg, most preferably at least 17 kg. This means that a material with sufficient stability can be selected for the support device, e.g. metal, in particular aluminum. For example, the support device is formed at least predominantly (by weight) from a metal profile, in particular an aluminum profile. Preferably, the support device is formed, at least in sections, by a support frame or rack made from a metal profile, in particular an aluminum profile.

[0029] For example, the pumping device (a) can have a minimum flow rate of at least 0.5 m3 / h, 0.75 m 3 / h, 1.0 m 3 / h, 1.75 m 3 / h, 2.5 m 3 / h and / or (b) a maximum discharge rate of 10.0 m 3 / h, preferably 7.0 m 3 / h, particularly preferably 3.5 m 3 / h, more preferably 2.0 m 3 / h, most preferably 1.2 m 3 / h, and / or (c) a maximum delivery head of at least 5 m, preferably 15 m, particularly preferably 25 m, further preferably 35 m, and / or (d) a maximum delivery head of at most 70 m, preferably 50 m, particularly preferably 40 m, further preferably 30 m, most preferably 20 m. A pump device having such performance data has proven to be advantageous for the presently intended purpose. On the one hand, it has been found that due to the solar-powered water pumping, such low delivery rates are sufficient since this can occur over a correspondingly long period of time. Furthermore, the weight of pump devices having such performance data is low enough for the mobile irrigation device to be moved by a single person.

[0030] It has proven advantageous if the pumping device comprises a pump designed as an eccentric pump, preferably an eccentric screw pump. Alternatively or additionally, the pump of the pumping device can have a brushless drive motor. Optionally, the pumping device can be designed as a submersible pump, i.e., the drive motor of the pump or a pump housing enclosing the drive motor is arranged in the water to be extracted during normal operation.

[0031] The pump device can, for example, have a sieve on its suction side that is designed to prevent solids from being sucked into the pump. In other words, the sieve is arranged upstream of the pump. The sieve can prevent animals or other floating or suspended matter in the sucked-in water from being sucked in, so that the pump does not become clogged and no animals living in the area of the water intake are endangered. In particular, the sieve allows a pump with a simple design to be used for the pump device, since the pump itself does not need to be capable of pumping dirty water because protection from the sucked-in substances is ensured by the sieve. Alternatively, the pump device can comprise a protective water pump, with or without a sieve.The sieve means may, for example, comprise a grid with a mesh opening and / or mesh width of 2 mm to 4 mm, preferably 2.5 mm to 3.5 mm, particularly preferably 3.0 mm.

[0032] The support device can, for example, have (a) a maximum length of 3.5 m, preferably 3.0 m, particularly preferably 2.5 m, further preferably 2.0 m, most preferably 1.6 m, and / or (b) a length of at least 1.0 m, preferably 1.35 m, particularly preferably 1.4 m, further preferably 1.6 m, and / or (c) a maximum height of 2.0 m, preferably 1.75 m, particularly preferably 1.5 m, further preferably 1.2 m, and / or (d) a height of at least 0.3 m, preferably 0.6 m, particularly preferably 0.8 m, further preferably 1.0 m, further preferably 1.1 m, and / or (e) a maximum width of 2.0 m, preferably 1.5 m, particularly preferably 1.25 m, further preferably 1.1 m, and / or (f) a width of at least 0.5 m, preferably 0.75 m, particularly preferably 0.9 m, more preferably 1.0 m. A support device having the aforementioned dimensions has proven advantageous, since it is sufficiently large to stably accommodate and support the at least one solar module.Furthermore, a carrying device having the aforementioned dimensions can be comfortably grasped and carried by a single person.

[0033] Alternatively or additionally, the support device can have a volume in the range of 0.4 to 4.3 m 3 , preferably 0.85 to 2.0 m 3 , particularly preferably 1.0 to 1.6 m 3 , more preferably 1.20 to 1.4 m 3 , most preferably 1.25 to 1.35 m 3 include.

[0034] A carrying device in the above-mentioned volume range can enable good portability by a single person.

[0035] In a preferred embodiment, the mobile irrigation device, i.e. including the carrying device, solar device, anchoring means and pump device, can have a total weight of a maximum of 100 kg, preferably 80 kg, particularly preferably 75 kg, further preferably 70 kg, most preferably 65 kg. This total weight therefore also includes the at least one solar module, a converter or other control unit, optionally a radio module and cables such as power cables. The at least one solar module preferably has a weight in the range of 2.0 to 12 kg, preferably 4.0 to 10.0 kg, particularly preferably 6.0 to 9.0 kg, further preferably 7.0 to 8.0 kg. The pump of the pump device can, for example, have a weight of 4.0 to 13 kg, preferably 6.0 to 11.0 kg, particularly preferably 7.0 to 10.0 kg, further preferably 8.0 to 9.0 kg.

[0036] It is possible for the mobile irrigation device to comprise a positioning unit by means of which the position of the solar device and / or the support device and / or the pump device can be determined. For example, position information provided by the positioning unit can be used to document the operating location of the mobile irrigation device. In particular, its mobile use can be documented.

[0037] The innovation is explained in more detail using exemplary embodiments in the drawings. The drawings show: Fig. 1 shows a schematic diagram of a carrying device in side view according to a first embodiment; Fig. 2 a schematic diagram of a support device according to Fig. 1 in a front view; Fig. 3 a perspective schematic diagram of a support and solar device according to Fig. 1 in a rear view; Fig. 4 a schematic representation of a carrying device according to a second embodiment in front view; Fig. 5 a perspective schematic diagram of an irrigation device according to an embodiment; Fig. 6 a schematic representation of a frame component (fifth frame body) of the support device according to Fig. 3.

[0038] The figures show a mobile irrigation device 1 for irrigating a landscaped area 2. The irrigation device 1 comprises a solar device comprising at least one solar module 3, 3' for solar-assisted generation of electrical energy, as well as a support device 4 to which the at least one solar module 3, 3' is or can be releasably attached. The irrigation device 1 further comprises at least one anchoring means 5 by means of which the support device 4 can be releasably anchored to a landscaped area 2. Thus, first, the support device 4 can be attached to the landscaped area 2 and then the at least one solar module 3, 3' can be attached to the support device 4. Furthermore, the irrigation device 1 has a pump device 6, which can be or is supplied with electrical energy by the solar device in order to pump water from an extraction location 7 to a destination location 8 for irrigating the landscaped area 2.For this purpose, the pumping device 6 comprises a pump and a suction hose attached to the pump, which is arranged at a water source (e.g., a well and / or standing or flowing body of water) to suck in the water there. On the pressure side, the pump is connected either directly or via a pipe and / or hose to a target location on the landscaped area in order to irrigate it.

[0039] At least two, preferably at least three, particularly preferably at least four, solar modules 3, 3' are detachably attached or can be attached to the support device 4. A solar module 3, 3' has a size or a main area of (a) a maximum of 62500 cm 2 , preferably 40000 cm 2 , particularly preferably 25500 cm 2 , more preferably 15000 cm 2 , most preferably 10000 cm 2 , and / or (b) at least 5500 cm 2 , preferably 6400 cm 2 , particularly preferably 10000 cm 2 , more preferably 14400 cm2 , on.

[0040] The solar device is detachably connected to the pump device 6 via a power cable 9, wherein (a) the power cable 9 has a length of at least 1 m, preferably at least 2 m, particularly preferably at least 4 m, further preferably at least 8 m, most preferably at least 12 m, and / or (b) the power cable 9 has a properties suitable for use of the power cable 9 for long-term application in above-ground outdoor areas. For example, a first current-conducting connection can be present between the at least one solar module 3, 3' and a control and / or regulating unit 28 (e.g., a controller and / or a rectifier); this connection can be established, for example, via a cable 23. The control and / or regulating unit 28 can form a component of the solar device.The control and / or regulating unit 28 can be connected to the pump device 6, in particular to the pump 16 of the pump device 6, via the power cable 9 and supply it with electrical energy.

[0041] As exemplified in the first, in Fig. 1, the support device 4 can have a prismatic basic structure. The basic structure can be formed from a cuboid-shaped partial base section and a wedge-shaped partial base section. The cuboid-shaped partial base section preferably faces the installation surface 25. A lower end, or end facing an installation surface 25, of a receiving structure 26 of the support device 4 for receiving the at least one solar module 3, 3' can, for example, have a distance 27 of at least 10 cm, preferably 20 cm, particularly preferably 25 cm, further preferably 30 cm, from the installation surface 25. Alternatively or additionally, the lower end of the receiving structure 26 of the support device 4 facing the installation surface 25 for receiving the at least one solar module 3, 3' can have a maximum distance 27 from the installation surface 25 of 2.0 m, preferably 1.0 m, preferably 0.6 m, particularly preferably 0.4 m, further preferably 0.35 m.This distance 27 allows for a sufficient minimum spacing between the solar module 3, 3' carried by the support device 4 and the installation surface 25, which is particularly advantageous for minimizing any wind loads on the mobile irrigation device 1. It also provides a sufficient height relative to the vegetation on the landscaped area 2, so that there is no significant shading of the solar modules 3, 3' by neighboring vegetation.

[0042] The carrying device 4 can, for example, have a weight of maximum 50 kg, preferably maximum 30 kg, particularly preferably maximum 20 kg, further preferably maximum 15 kg, most preferably maximum 10 kg.

[0043] The support device 4 can, for example, be designed at least in sections, preferably predominantly, particularly preferably completely, as a frame having a strut 10, 10', cf. in particular Fig. 1 to 3. Adjacent struts 10, 10' can be connected to one another, for example, via welded joints, and together form a frame. At least two struts 10, 10' of the support device 4 can preferably be connected to one another or connectable in a detachable manner, in particular detachable without tools. A connection of at least one strut 10, 10' to another component of the support device 4, e.g., a node element, can also be detachable (e.g., screw connection) or non-detachable (e.g., welded connection), in particular detachable without tools. The support device 4 can, for example, be made of metal. The support device 4 can preferably consist of at least two struts 10, 10' made of steel or aluminum.

[0044] The at least one solar module 3, 3' can, for example, be attached to the support device 4 without tools and / or detachably attached from the support device 4 without tools. For example, the at least one solar module 3, 3' can be attached to the support device 4 via a snap-lock mechanism. Alternatively or additionally, the support device 4 can be released manually and without tools; for example, the connection between the at least one solar module 3, 3' and the support device 4 can be released by actuating a release mechanism using muscle power.

[0045] For example, the at least one solar module 3, 3' is accommodated in a plug-in device arranged (e.g., attached) or formed on the support device side. For example, the plug-in device can comprise at least one retaining element 29, e.g., formed as an L-shaped bracket, wherein the at least one solar module 3, 3' can be inserted and / or pushed into the receiving space formed by the retaining element 29.

[0046] In the Fig. 1 and Fig. In the embodiment shown in Figure 2, holding elements 29 are arranged on an upper and a lower, horizontally extending strut 10, 10' (cf. frame body 36) of a support device 4 designed as a frame, which holding elements define an insertion channel into which the at least one solar module 3, 3' can be inserted. Fig. In the embodiment shown in Figure 1, the support device 4 supports four solar modules 3, 3', 3", wherein each solar module 3, 3', 3" is held on an outward-facing side by a holding element 29. A clamping element of a clamping unit 22 is arranged or formed in a central separating gap between two adjacent solar modules 3, 3', 3". In general, for example, a clamping unit 22 can be provided, by means of which a clamping attachment of the at least one solar module 3, 3' to the support device 4 can be carried out. For example, the clamping unit 22 has an eccentric that can be actuated via a handle (e.g. similar to a manual quick adjuster of a bicycle seat post).

[0047] For example, the clamping unit 22 comprises at least one clamping element designed as a T-body, which has two receiving spaces, in each of which a solar module 3, 3', 3" of two adjacently arranged solar modules 3, 3', 3" can be received. The T-body can be releasably fastened to the frame, in particular to the frame body sections 37, 38 of the fifth frame body 36, for example by means of a screw or other fastening means. For example, the fastening means is designed such that it can be fixed to the support device 4, in particular to the frame, without tools and / or can be released from the support device 4, in particular from the frame, without tools. For example, a fastening means can be designed as a wing screw or knurled screw or in the manner of a quick-release fastener with a handle.

[0048] Preferably, the clamping elements of the clamping unit 22 are fastened to connecting struts or cross struts connecting horizontal struts 10, 10', or these connecting struts or cross struts have receiving openings for receiving components of the clamping elements.

[0049] The at least one anchoring means 5 can, for example, form a component separate from the support device 4, which penetrates into the landscape area 2 with a penetration section 11 for anchoring the support device 4 to the landscape area 2 and forms a positive and / or non-positive connection with a holding section 12 with the support device 4, in particular the anchoring means-side holding section 12 encompasses a counter-holding section 13 of the support device 4.

[0050] The at least one anchoring means 5 can, for example, form a component of the support device 4, wherein a penetration section 11 of the anchoring means 5 penetrates into the landscape area 2 to anchor the support device 4 to the landscape area 2. For example, the anchoring means 5 is designed as a tip that is permanently attached, i.e., not detachable without destruction, to a base structure of the support device 4. The penetration section can have a pyramidal or conical basic shape, wherein its tapered region serves to penetrate the landscape area 2.Preferably, the anchoring means 5 comprises at least two, preferably at least three, particularly preferably at least four, anchoring elements 24, 24', 24", which, when the mobile irrigation device 1 is set up as intended, are spaced apart from one another, each penetrate into the landscape area 2 and ensure stable anchoring of the support device 4 to the landscape area 2.

[0051] The support device 4 can, for example, have at least one footrest section 14, by means of which a person can place at least one foot, and in doing so, their weight can be or applies at least partially to the support device 4 via the at least one footrest section 14 as a compressive force directed in the direction of the landscape area 2. The at least one footrest section 14 is rigidly connected to the anchoring means 5 such that when a compressive force is applied to the at least one footrest section 14, this compressive force is transferred via the support device 4 to the anchoring means 5, in particular without causing any plastic and / or elastic deformation of the support device 4, so that the compressive force applied to the anchoring means 5 can be used to at least partially penetrate the anchoring means-side penetration section 11 into the landscape area 2.Preferably, at least one footrest section 14 can be designed as a corner stiffening element of at least two interconnected struts 10, 10' of the support device 4.

[0052] It is possible for the irrigation device 1 to have a radio module 15 by means of which a radio connection to a mobile terminal can be generated, wherein control information controlling at least one operating parameter of the pump device 6 and / or operating state information describing an operating state of the pump device 6 and / or the solar device can be transmitted via the radio module 15.

[0053] The support device 4 can, for example, be designed to be at least partially foldable and / or pluggable and / or foldable. For this purpose, at least one strut 10, 10' or at least two struts 10, 10' can be designed to be foldable and / or pluggable and / or foldable at their connection point. This increases the compactness of the support device 4 when not in use. The support device 4 can also be separated into several parts, thereby improving its transportability and handling, especially when handled by a single person.

[0054] For example, in Fig. 3, the support device 4 can be designed, in particular, like a frame and have at least two, preferably at least three, sections that can be detachably connected to one another, cf. connection interface 30. For example, the support device 4 can have a plurality of frame bodies 32, 33, 34, 35, 35 that can be detachably connected to one another, in particular pluggable and / or lockable. For example, a first frame body 32 forms a first side part and a second frame body 33 forms a second side part of the support device, wherein the two frame bodies 32, 33 or the two side parts are each connectable or connected to a third frame body 34, a fourth frame body 35 and a fifth frame body 36 via connection interfaces 30, which are in particular of identical design.The connection interfaces 30 for connecting the frame bodies 32, 33, 34, 35, 36 can preferably each be designed as a lockable plug connection. For example, two frame bodies 32, 33, 34, 35, 36 to be connected are plugged together and locked by means of a split. It is possible for at least one frame body (here: 36) to have at least two frame body sections 37, 38 that are connected to one another via a hinge 31. This makes it possible to fold the frame body (here: 36) into a non-use position via the hinge 31, thus achieving a compact packing volume.

[0055] The support device 4 can, for example, be configured such that the at least one solar module 3, 3', in particular all solar modules 3, 3' arranged on the support device 4, are carried or arranged at an angle α in the range of 25° to 60°, preferably 30° to 50°, particularly preferably 34° to 46°, further preferably at an angle α of 35° or 45°, to a mounting surface.

[0056] The support device 4 and the components attached thereto, with the exception of the solar modules 3, 3' and the anchoring means 5 detachably attachable to the support device 4, can, for example, have a maximum weight of 70 kg, preferably a maximum of 50 kg, particularly preferably a maximum of 35 kg, particularly preferably a maximum of 30 kg, most preferably a maximum of 25 kg. The pump device 6 can, for example, (a) have a minimum delivery rate of at least 0.5 m 3 / h, 0.75 m 3 / h, 1.0 m 3 / h, 1.75 m 3 / h, 2.5 m 3 / h and / or a maximum flow rate of 10.0 m 3 / h, preferably 7.0 m 3 / h, particularly preferably 3.5 m 3 / h, more preferably 2.0 m 3 / h, most preferably 1.2 m 3 / h, and / or (b) a maximum delivery head of at least 5 m, preferably 15 m, particularly preferably 25 m, further preferably 35 m, and / or a maximum delivery head of at most 70 m, preferably 50 m, particularly preferably 40 m, further preferably 30 m, most preferably 20 m.

[0057] The pump device 6 can have a pump 16, wherein a sieve 18 is arranged or configured upstream of the pump 16 and is configured to prevent solids from being sucked into the pump 16. For example, the sieve 18 is configured as a cuboid-shaped body and has passage openings on its surface (e.g., a grid structure) that are selected to be so small that foreign substances cannot penetrate these passage openings. Preferably, the sieve 18 has a grid with a mesh opening 45 and / or mesh width 46 of 2 mm to 4 mm, preferably 2.5 mm to 3.5 mm, particularly preferably 3.0 mm.

[0058] Alternatively or additionally, the pump device 6 can comprise a pump 16 and a collecting container 40 having through-openings 39, wherein the collecting container 40 is arranged downstream of the pump 16 and the water pumped by the pump 16 passes through or flows through the through-openings 39 of the collecting container 40 before exiting at or into the destination 8. In other words, a screening device can be arranged or configured downstream of the pump 16, which is configured to prevent any solids or other elements in the pumped water from freely escaping at the destination 8 downstream of the pump 16. For example, an outlet hose 17 is arranged at an outlet opening of the pump 16 in order to direct the water pumped by the pump 16 to the collecting container 40 placed at the destination 8 by means of the outlet hose 17. For this purpose, an outlet end of the outlet hose 17 can open into an interior of the collecting container 40.

[0059] The passage openings 39 of the collecting container 40 can, for example, have a smaller mesh size 41 and / or a smaller mesh opening 42 than the sieve 18. In other words, the collecting container 40 and the sieve 18 are designed such that coarser substances can be sucked into the pump 16 upstream of the pump 16 than can be discharged at the destination 8. For example, the size difference between the mesh size 41 and / or the mesh opening 42 of the collecting container 40 and the sieve 18 is at least a factor of 1.1, preferably 1.5, particularly preferably 2.0, further preferably 2.5, most preferably 3.0. Alternatively or additionally, the size difference between the maximum substances penetrating the collecting container and the sieve 18 is a maximum factor of 30, preferably 20, particularly preferably 10, further preferably 7, most preferably 4.

[0060] In a specific embodiment, the sieve 18 can have a mesh size 45 and / or mesh opening 46 in the range of 2.0 to 4.0 mm, and the passage openings 29 of the collecting container 40 can have a mesh opening 42 or mesh size 41 of 0.25 to 1.9 mm, preferably 0.5 to 1.5 mm. This configuration of the collecting container 40 and sieve 18 has the advantage that there is little or no significant pressure loss on the suction side of the pump 16 due to the larger mesh size 45 of the sieve 18. Although smaller animals and / or solids can be sucked in from the suction location 7, their discharge or escape at the destination 8 is prevented by the collecting container 40, since these animals and / or solids cannot penetrate the passage openings 39 of the collecting container 40 and thus do not reach the open landscape of the destination 8, but remain or are collected in the collecting container 40.This makes it possible to prevent macrozoobenthos from the extraction location 7 from being transferred to the target location 8 in a simple, convenient and energy-efficient manner.

[0061] The collecting tank 40 preferably has a buffer volume so that a larger amount of water can be accommodated, which can drain away, e.g., when the pump 16 is stopped. The buffer volume makes it possible for the pumped water to drain away through the through-openings 39 of the collecting tank 40 despite the collection or gravity-induced settling of filtrate 44 in the collecting tank 40, in a bottom region of the collecting tank 40. It can prove advantageous if a bottom region and a side wall region of the collecting tank 40 are provided with through-openings 39. For this purpose, the collecting tank 40 has a larger passage cross-section of the passage openings than the suction-side passage cross-section. In other words, the effective passage area downstream of the pump 16 is larger than upstream, but the clearance of the individual openings upstream is larger than downstream of the pump 16.

[0062] It is possible for the mobile irrigation device 1 to have a detection device 43 configured to generate a water level in the collecting container 40 and / or detection information describing the degree of blockage of the passage openings 39 or the degree of permeability of the passage openings 39 of the collecting container 40. For example, the pump 16 of the pump device 6 can be operated depending on the detection information. In this case, the detection information can, for example, be transmitted to the control and / or regulation unit 28 so that the pump 16 can be controlled and / or regulated depending on the detection information. The detection device 43 can, for example, detect the water level optically (e.g., camera-supported) and / or tactilely (e.g., by means of a float and / or by means of weight detection).If the collection container 40 no longer drains water, the pump 16 can be deactivated to prevent the collection container 40 from overflowing. Alternatively or additionally, the detection information can be output; in particular, the detection information can be transmitted wirelessly to a mobile device, so that an operator can be notified of a collection container 40 that needs to be cleaned and / or emptied. Optionally, the collection container 40 can have feet for placement on a support surface.

[0063] The support device 4 can, for example, have (a) a length 19 of at most 3.5 m, preferably 3.0 m, particularly preferably 2.5 m, further preferably 2.0 m, most preferably 1.6 m, and / or (b) a length 19 of at least 1.0 m, preferably 1.35 m, particularly preferably 1.4 m, further preferably 1.5 m, and / or (c) a height 20 of at most 2.0 m, preferably 1.75 m, particularly preferably 1.5 m, further preferably 1.2 m, and / or (d) a height 20 of at least 0.3 m, preferably 0.6 m, particularly preferably 0.8 m, further preferably 1.0 m, further preferably 1.1 m, and / or (e) a width 21 of at most 2.0 m, preferably 1.5 m, particularly preferably 1.25 m, further preferably 1.1 m, and / or (f) a width 21 of at least 0.5 m, preferably 0.75 m, particularly preferably 0.9 m, further preferably 1.0 m, cf. Fig. 1 and Fig. 2 . Preferably, the support device 4 can have a volume in the range of 0.4 to 4.3 m 3 , preferably 0.85 to 2.0 m 3 , particularly preferably 1.0 to 1.6 m3 , more preferably 1.20 to 1.4 m 3 , most preferably 1.25 to 1.35 m 3 The height 20 means a maximum height 20 of the support device 4 relative to a mounting surface 25, cf. Fig. 1.

[0064] For example, the mobile irrigation device 1 has a position-determining unit by means of which the position of the solar device and / or the support device 4 and / or the pump device 6 can be determined. Alternatively or additionally, the position-determining unit can be used to detect or determine the location of an intake opening of the pump device 6, i.e., for example, an intake opening of an intake hose of the pump device 6, and / or an outlet opening of the pump device 6, i.e., for example, an outlet opening of an outlet hose 17 of the pump device 6, and output this as position information. This makes it possible, for example, to determine the location of the water extraction, the extraction location 7, and / or the irrigation location, the target location 8, and to generate position information.This position information can be assigned, in particular linked, to time information and / or operating status information of the solar device and / or the pumping device for documentation purposes. This allows, for example, a statement to be made about the amount of water withdrawn from a suction location 7 and / or the extent or quantity of irrigation at the target location 8, and for example, to be archived. The position information can be transmitted, for example, via the radio module 15, to a mobile device.
