Description

Technical Field

[0001] This invention belongs to the field of ambient lighting, and particularly relates to an energy-saving ambient lighting device for water features and fountains. Background Technology

[0002] A fountain is a device that creates water features by spraying and spouting water. Various effects can be created by changing the frequency of the water jets. However, ambient lighting is also used in conjunction with fountains. Fountain ambient lighting, also known as water droplet lights, illuminates the water jets with different lights, making the water jets of the fountain have different colors and creating different light and shadow changes in the fountain landscape.

[0003] One type of fountain ambient light is installed on the ground, mostly using expansion bolts to fix it to the ground, with the fountain water pipe placed in the middle of the ambient light.

[0004] The existing ambient lighting requires multiple bolts to be turned to secure it. Furthermore, during disassembly and maintenance, workers must remove all the bolts before they can take out and replace the ambient lighting, which is very inconvenient and wastes a lot of time, resulting in reduced maintenance efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving ambient light device for water features and fountains, aiming to solve the technical problem of low maintenance efficiency caused by fixing ambient lights with bolts in the prior art.

[0006] The present invention is implemented as follows: an energy-saving ambient light device for a water feature fountain includes a mounting base and an inner mounting core. The inner mounting core is installed inside the mounting base. Limiting strips are fixedly connected to both sides of the inner mounting core. The mounting base has a limiting groove adapted to the limiting strips inside. An outer rotating cylinder is rotatably mounted on the outside of the inner mounting core. The outer rotating cylinder has a notch for the limiting strips to move.

[0007] A fixing mechanism is installed between the limiting strip, the outer rotating cylinder and the mounting base. The fixing mechanism is used to fix the inner mounting core to the mounting base.

[0008] An ambient light assembly and a transparent sealing ring are mounted on the top of the inner mounting core. The ambient light assembly is embedded in the inner mounting core, and the transparent sealing ring is located above the ambient light assembly and seals the ambient light assembly. The ambient light assembly can generate light, which shines on the fountain through the transparent sealing ring.

[0009] Further technical solution: The fixing mechanism includes a movable cavity formed on the limiting strip, a fixed ball installed in the movable cavity, an extension hole formed on the side of the movable cavity, one end of the fixed ball can extend out from the extension hole, an extrusion strip is fixedly connected to the side of the notch, the extrusion strip is an arc-shaped strip, the axis of the extrusion strip coincides with the axis of the inner core, a through hole is formed on the limiting strip for the extrusion strip to pass through, an inclined surface adapted to the fixed ball is formed at the end of the extrusion strip, and a fixing groove adapted to the fixed ball is formed in the limiting groove.

[0010] A further technical solution: There are at least two fixing mechanisms, and the fixing mechanisms are evenly installed on the two limiting strips to make the inner mounting core more securely installed.

[0011] Further technical solution: The ambient light assembly includes a mounting shell, which is embedded in an inner mounting core. A ring-shaped circuit board is installed inside the mounting shell, and multiple LED beads are arranged on the ring-shaped circuit board.

[0012] Further technical solution: The mounting shell is rotatably mounted on the inner mounting core. To enable power supply, the ambient light assembly also includes two fixed electrode rings and two movable electrode rings. The two fixed electrode rings are mounted on the inner mounting core and are respectively connected to the positive and negative terminals of the external power supply. The two movable electrode rings are mounted on the mounting shell and are respectively electrically connected to the positive and negative terminals of the annular circuit board. The two fixed electrode rings are in contact with the two movable electrode rings respectively.

[0013] The inner mounting core is also equipped with a hydrodynamic mechanism. One end of the hydrodynamic mechanism is connected to the mounting shell for transmission, and the hydrodynamic mechanism is used to drive the mounting shell to rotate.

[0014] Further technical solution: The hydrodynamic mechanism includes a rotating cylinder rotatably installed inside the inner mounting core, a rotating ring is provided on the rotating cylinder, a rotating groove adapted to the rotating ring is opened on the inner mounting core, and a spiral auger is fixedly connected inside the rotating cylinder;

[0015] A transmission rod is rotatably mounted on the inner mounting core. A second gear is fixedly mounted on one end of the transmission rod. An external gear ring is mounted on the rotating ring. The second gear and the external gear ring are meshed and connected. A first gear is fixedly mounted on the other end of the transmission rod. An internal gear ring is fixedly mounted on the bottom of the mounting shell. The internal gear ring and the first gear are meshed and connected.

[0016] A further technical solution: the outer rotating cylinder is threaded with a limiting screw, and the side of the inner mounting core is provided with a limiting arc groove that matches the limiting screw.

[0017] A further technical solution: A limiting mechanism is also installed between the outer rotating cylinder and the inner mounting core. The limiting mechanism includes an installation groove formed on the inner mounting core, a limiting rod is slidably installed in the installation groove, and a compression spring is connected between the limiting rod and the inner mounting core.

[0018] The outer rotating cylinder is provided with a locking groove, and a limit slot is provided on the side of the locking groove near the mounting groove. One end of the limit slot passes through the outer rotating cylinder, and a top column is slidably installed inside the limit slot. A pressing end is fixedly connected to one end of the top column near the locking groove.

[0019] The energy-saving ambient lighting device for the water feature fountain also includes specialized tools used to remove the restriction on the external rotation of the limiting mechanism.

[0020] Further technical solution: The professional tool is a disassembly handle, which includes a handle, and a locking block is fixedly connected to the end of the handle via a connecting rod. The length of the locking block is not greater than the length of the locking groove, and the side of the locking block has a beveled surface.

[0021] Both sides of the lock groove are provided with side grooves that are adapted to the lock block, and the depth of the side grooves is less than the depth of the lock groove.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. This invention, by setting up a mounting base, an inner mounting core, and an outer rotating cylinder, allows for the following steps when installing a light fixture: first, the mounting base is fixedly installed on the ground; then, the assembled outer rotating cylinder, inner mounting core, ambient light assembly, and transparent sealing ring are inserted into the mounting base. Rotating the outer rotating cylinder causes it to fix the inner mounting core onto the mounting base via a fixing mechanism. During maintenance, simply reverse the rotation of the outer rotating cylinder to remove the inner mounting core from the mounting base and replace it with a new one. This makes disassembly and assembly more convenient and greatly improves maintenance efficiency.

[0024] 2. The present invention, by rotating the ambient light assembly on the inner mounting core and driving it through a water-powered mechanism, which uses sprayed water as power to drive the ambient light assembly to rotate, not only greatly improves the aesthetics of the ambient light, but also eliminates the need for an additional motor, thus saving energy.

[0025] 3. In this invention, by setting a limiting mechanism, after the extrusion strip is fully inserted into the through hole, the limiting rod is just inserted into the limiting slot, thereby fixing the outer rotating cylinder and preventing the outer rotating cylinder from rotating at will, thereby preventing the extrusion strip from coming out of the through hole and preventing the inner core from loosening.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0037] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0038] like Figures 1-9 As shown, an energy-saving ambient light device for a water feature fountain provided by the present invention includes a mounting base 1 and an inner mounting core 3. The inner mounting core 3 is installed inside the mounting base 1. Limiting strips 6 are fixedly connected to both sides of the inner mounting core 3. A limiting groove 13 adapted to the limiting strip 6 is opened inside the mounting base 1. An outer rotating cylinder 2 is rotatably mounted on the outside of the inner mounting core 3. A notch 14 for the limiting strip 6 to move is opened on the outer rotating cylinder 2.

[0039] A fixing mechanism 8 is installed between the limiting strip 6, the outer rotating cylinder 2 and the mounting base 1. The fixing mechanism 8 is used to fix the inner mounting core 3 to the mounting base 1.

[0040] An ambient light assembly 7 and a transparent sealing ring 4 are installed on the top of the inner mounting core 3. The ambient light assembly 7 is embedded in the inner mounting core 3, and the transparent sealing ring 4 is located above the ambient light assembly 7 and seals the ambient light assembly 7. The ambient light assembly 7 can generate light, and the light shines on the fountain through the transparent sealing ring 4.

[0041] Specifically, during installation, the mounting base 1 can be fixed to the ground using expansion bolts or other methods. Then, the limiting strip 6 is aligned with the limiting groove 13, and the assembled outer rotating cylinder 2, inner mounting core 3, ambient light assembly 7, and transparent sealing ring 4 are inserted into the mounting base 1. The outer rotating cylinder 2 is rotated, and the outer rotating cylinder 2 will fix the inner mounting core 3 to the mounting base 1 through the fixing mechanism 8. The water pipe of the fountain will be located inside the inner mounting core 3, and water will spray out from the middle of the inner mounting core 3. The light emitted by the ambient light assembly 7 will illuminate the water flow to provide lighting.

[0042] During maintenance, the inner mounting core 3 can be removed from the mounting base 1 by driving the outer rotating cylinder 2, and a new inner mounting core 3 can be replaced. Damaged inner mounting core 3 can be returned to the manufacturer for repair, which makes disassembly and assembly more convenient and greatly improves maintenance efficiency.

[0043] This invention provides an energy-saving ambient lighting device for a water feature fountain. In this embodiment, the fixing mechanism 8 includes a movable cavity 82 formed on a limiting strip 6. A fixed ball 81 is installed in the movable cavity 82. An extension hole is formed on the side of the movable cavity 82, and one end of the fixed ball 81 can extend out of the extension hole. An extrusion strip 83 is fixedly connected to the side of the notch 14. The extrusion strip 83 is an arc-shaped strip, and the axis of the extrusion strip 83 coincides with the axis of the core 3 installed inside. A through hole 84 is formed on the limiting strip 6 for the extrusion strip 83 to pass through. An inclined surface adapted to the fixed ball 81 is formed at the end of the extrusion strip 83. A fixing groove 85 adapted to the fixed ball 81 is formed in the limiting groove 13.

[0044] Specifically, after the inner mounting core 3 is inserted into the mounting base 1, the fixing groove 85 is located on the side of the fixing ball 81. At this time, the outer rotating cylinder 2 is rotated, and the outer rotating cylinder 2 drives the extrusion strip 83 to rotate. One end of the extrusion strip 83 passes into the through hole 84 and extrudes the fixing ball 81, thereby extruding one end of the fixing ball 81 into the fixing groove 85, and thus fixing the inner mounting core 3 into the mounting base 1.

[0045] During disassembly, simply reverse the outer rotating cylinder 2 so that the extrusion strip 83 no longer obstructs the fixing ball 81, then lift the inner mounting core 3. The edge of the fixing groove 85 will then press the fixing ball 81 into the movable cavity 82, and the inner mounting core 3 can then be easily removed from the mounting base 1 for replacement.

[0046] The present invention provides an energy-saving ambient light device for water feature fountains. In this embodiment, there are at least two fixing mechanisms 8, and multiple fixing mechanisms 8 are evenly installed on two limiting strips 6 to make the inner mounting core 3 more securely installed.

[0047] The present invention provides an energy-saving ambient light device for water feature fountains. In this embodiment, the ambient light component 7 includes a mounting shell 71, which is embedded in the inner mounting core 3. A ring circuit board 72 is installed inside the mounting shell 71, and a plurality of LED beads 73 are arranged on the ring circuit board 72.

[0048] Specifically, in this embodiment, there are 5 LED beads 73, and the 5 LED beads 73 emit different colors, thus making the ambient light more beautiful.

[0049] The present invention provides an energy-saving ambient light device for a water feature fountain. To further enhance the ambient light effect, in this embodiment, the mounting shell 71 is rotatably mounted on the inner mounting core 3. To achieve power supply, the ambient light assembly 7 further includes two fixed electrode rings 74 and two movable electrode rings 75. The two fixed electrode rings 74 are mounted on the inner mounting core 3 and are respectively connected to the positive and negative terminals of an external power supply. The two movable electrode rings 75 are mounted on the mounting shell 71 and are respectively electrically connected to the positive and negative terminals of the annular circuit board 72. The two fixed electrode rings 74 are in contact with the two movable electrode rings 75.

[0050] The inner mounting core 3 is also equipped with a hydrodynamic mechanism 5. One end of the hydrodynamic mechanism 5 is connected to the mounting shell 71 for transmission. The hydrodynamic mechanism 5 is used to drive the mounting shell 71 to rotate.

[0051] Specifically, when powered, the external power supply can be directly connected to the wires on the inner mounting core 3 via a wire. The wires on the inner mounting core 3 are electrically connected to the two fixed electrode rings 74. This method provides better sealing, but the connected wires need to be disconnected during maintenance.

[0052] Alternatively, the external power supply wire can be connected to the mounting base 1, and a contact electrode can be set between the mounting base 1 and the inner mounting core 3. After the inner mounting core 3 is installed in place, an electrical connection can be achieved between the mounting base 1 and the inner mounting core 3. However, the sealing performance is lower in this case. The advantage is that it is more convenient to repair and replace the inner mounting core 3, and there is no need to worry about the wire breaking.

[0053] The present invention provides an energy-saving ambient light device for water feature fountains. In this embodiment, the hydrodynamic mechanism 5 includes a rotating cylinder 57 rotatably installed inside the inner mounting core 3. A rotating ring 58 is provided on the rotating cylinder 57. A rotating groove adapted to the rotating ring 58 is opened on the inner mounting core 3. A spiral auger 56 is fixedly connected inside the rotating cylinder 57.

[0054] A transmission rod 52 is rotatably mounted on the inner mounting core 3. A second gear 53 is fixedly mounted on one end of the transmission rod 52. An external gear ring 55 is mounted on the rotating ring 58. The second gear 53 and the external gear ring 55 are meshed together. A first gear 51 is fixedly mounted on the other end of the transmission rod 52. An internal gear ring 54 is fixedly mounted on the bottom of the mounting shell 71. The internal gear ring 54 and the first gear 51 are meshed together.

[0055] Specifically, when installing the inner core 3, the fountain's water pipe is installed below the rotating cylinder 57. When spraying water, the water flow passes through the inside of the rotating cylinder 57 and drives the rotating cylinder 57 to rotate via the spiral auger 56. The rotating cylinder 57 drives the second gear 53 to rotate via the outer gear ring 55. The second gear 53 drives the first gear 51 to rotate via the transmission rod 52. The first gear 51 drives the inner gear ring 54 and the mounting shell 71 to rotate, thereby causing the mounting shell 71 to drive multiple LED beads 73 to rotate, making the lights of different colors rotate and increasing the visual effect of the ambient lighting. Moreover, this invention does not require an additional motor and uses water flow to provide power, making it more energy-efficient.

[0056] The present invention provides an energy-saving ambient light device for water feature fountains. In order to prevent the outer rotating cylinder 2 and the inner mounting core 3 from separating, in this embodiment, the outer rotating cylinder 2 is threaded with a limiting screw 10, and the side of the inner mounting core 3 is provided with a limiting arc groove 11 that is adapted to the limiting screw 10.

[0057] Specifically, during assembly, the inner mounting core 3 is inserted into the interior of the outer rotating cylinder 2, and the limiting arc groove 11 is located on the side of the limiting screw 10. Then, the limiting screw 10 is tightened so that one end of the limiting screw 10 extends into the limiting arc groove 11, which can fix the outer rotating cylinder 2 and the inner mounting core 3 in the vertical direction, preventing the inner mounting core 3 from coming out of the outer rotating cylinder 2. When the outer rotating cylinder 2 rotates, one end of the limiting screw 10 slides in the limiting arc groove 11, without affecting the movement of the outer rotating cylinder 2.

[0058] The present invention provides an energy-saving ambient light device for a water feature fountain. After the inner mounting core 3 is installed inside the mounting base 1, the outer rotating cylinder 2 may rotate automatically without being limited, thereby causing the extrusion strip 83 to exit from the through hole 84. This leads to loosening between the inner mounting core 3 and the mounting base 1, and the inner mounting core 3 will eventually be washed out by the water flow, resulting in damage to the inner mounting core 3. Therefore, in this embodiment, a limiting mechanism 9 is also installed between the outer rotating cylinder 2 and the inner mounting core 3. The limiting mechanism 9 includes an installation groove 98 opened on the inner mounting core 3, a limiting rod 96 is slidably installed in the installation groove 98, and a compression spring 97 is connected between the limiting rod 96 and the inner mounting core 3.

[0059] The outer rotating cylinder 2 is provided with a locking groove 92. A limiting slot 94 is provided on the side of the locking groove 92 near the mounting groove 98. One end of the limiting slot 94 passes through the outer rotating cylinder 2. A top post 95 is slidably installed inside the limiting slot 94. A pressing end 93 is fixedly connected to one end of the top post 95 near the locking groove 92.

[0060] The energy-saving ambient lighting device for the water feature fountain also includes a professional tool used to release the restriction of the limiting mechanism 9 on the external rotating cylinder 2.

[0061] Specifically, when the extrusion bar 83 is fully inserted into the through hole 84, the limiting rod 96 is just inserted into the limiting slot 94.

[0062] To prevent foreign objects from entering the lock groove 92, a blocking plate 12 is also installed at the top of the lock groove 92.

[0063] When installing the inner mounting core 3, after the inner mounting core 3 is inserted into the mounting base 1, the outer rotating cylinder 2 is rotated. The outer rotating cylinder 2 drives the extrusion strip 83 to rotate. The extrusion strip 83 passes into the through hole 84 and extrudes the fixing ball 81, so that the fixing ball 81 is extruded into the fixing groove 85. When the limiting slot 94 rotates to the side of the mounting groove 98 (the axis of the limiting slot 94 and the axis of the mounting groove 98 coincide), under the action of the compression spring 97, the limiting rod 96 is inserted into the limiting slot 94, thereby fixing the outer rotating cylinder 2 and preventing the outer rotating cylinder 2 from rotating arbitrarily, thereby preventing the extrusion strip 83 from coming out of the through hole 84 and preventing the inner mounting core 3 from loosening.

[0064] During disassembly, a professional tool is inserted into the lock groove 92 and the tool is used to press the extrusion end 93. The extrusion end 93 pushes the limit rod 96 out of the limit slot 94 through the top post 95. At this time, the outer rotating cylinder 2 is rotated, and the extrusion strip 83 can be easily removed from the through hole 84. Then the inner mounting core 3 can be removed from the mounting base 1.

[0065] After assembly, to prevent the outer rotating cylinder 2 from rotating arbitrarily and affecting subsequent installation, a set of limiting mechanisms 9 has two parts. The other limiting mechanism 9 is set in the initial position. After the inner mounting core 3 is inserted into the outer rotating cylinder 2, the limiting rod 96 can be inserted into the limiting slot 94. At this time, the extrusion strip 83 is not inserted into the through hole 84. During installation, a professional tool is inserted into the two locking slots 92 and the limiting rod 96 is pushed into the mounting slot 98. Then, the outer rotating cylinder 2 is rotated with the professional tool until the extrusion strip 83 is inserted into the through hole 84. Then, the professional tool is pulled out, and the limiting rod 96 will be inserted into the other limiting slot 94, thus fixing the outer rotating cylinder 2.

[0066] Additionally, a mark can be made between the outer rotating cylinder 2 and the inner mounting core 3 to indicate the positions of the limiting slot 94 and the limiting rod 96, so that when the outer rotating cylinder 2 is rotated, the limiting slot 94 stops accurately to the side of the limiting rod 96.

[0067] The present invention provides an energy-saving ambient light device for water feature fountains. In this embodiment, the professional tool is a disassembly handle 15. The disassembly handle 15 includes a handle 154. The end of the handle 154 is fixedly connected to a locking block 151 via a connecting rod 153. The length of the locking block 151 is not greater than the length of the locking groove 92. The side of the locking block 151 is provided with a beveled surface 152.

[0068] Both sides of the lock groove 92 are provided with side grooves 91 that are adapted to the lock block 151, and the depth of the side grooves 91 is less than the depth of the lock groove 92.

[0069] Specifically, the height of the locking block 151 is no greater than the depth of the side groove 91. The number of locking blocks 151 is increased appropriately according to the number and position of the limiting mechanism 9.

[0070] When in use, insert the locking block 151 into the locking groove 92. The locking block 151 will then press the end 93 through the beveled surface 152. Then, turn the handle 154. The handle 154 will move the locking block 151, so that one end of the locking block 151 is inserted into the side groove 91. Continue to turn the handle 154, and the locking block 151 will drive the outer rotating cylinder 2 to rotate together. During installation, after the outer rotating cylinder 2 has rotated to the correct position, the locking block 151 can be removed from the locking groove 92. During disassembly, the outer rotating cylinder 2 can be lifted by the locking block 151, and the outer rotating cylinder 2 will drive the inner mounting core 3 to rise together.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0072] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
