DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figure 1-Figure 3The present invention provides a technical solution: a water-cooled heat dissipation LED plant lamp, the plant lamp comprising a shell 1, lamp beads 2, an aluminum substrate 3, an LED adapter 4, a cooling pipe 5 and a chiller 6, the lamp beads 2 are embedded in the shell 1 to form a lamp bead 2 matrix, the lamp bead 2 is used to convert electrical energy into light energy, the lamp bead 2 is electrically connected to the LED adapter 4, the LED adapter 4 provides a stable current for the lamp bead 2, the aluminum substrate 3 is connected to the lamp bead 2, the aluminum substrate 3 conducts the heat generated by the lamp bead 2 matrix, the cooling pipe 5 is arranged inside the shell 1, the chiller 6 is connected to the cooling pipe 5, the chiller 6 is used to transport coolant to the inside of the cooling pipe 5, and the cooling pipe 5 cools the lamp bead 2.

[0037] In a preferred embodiment, reference Figure 1 Several of the plant lights are connected by a delivery pipe 7, and a solenoid valve 8 is provided on the delivery pipe 7. The solenoid valve 8 is used to control the switch of the delivery pipe 7.

[0038] In a preferred embodiment, the cooling pipe 5 includes a U-shaped pipe 51 , one end of the U-shaped pipe 51 is connected to the chiller 6 via an input pipe, and the other end of the U-shaped pipe 51 is connected to an output pipe.

[0039] Specifically, the lamp beads 2 are used to emit light to illuminate the plants to promote plant growth. When the current temperature in the plant lamp is higher than the temperature threshold, the chiller 6 is turned on. The chiller 6 transports cold water to the cooling pipe 5. In this embodiment, the cooling pipe 5 adopts a U-shaped tube 51 to cool the plant lamp by water until the current temperature of the plant lamp is lower than the temperature threshold. The cold water pipe between two adjacent plant lamps is connected, and the solenoid valve 8 on the connecting pipe can be controlled to control the flow of cold water in adjacent plant lamps.

[0040] For example 2, please refer to Figure 4-Figure 7 , which is different from the first embodiment: the cooling pipe 5 includes a connecting pipe 1 52 and a connecting pipe 2 53, the connecting pipe 1 52 is connected to the chiller 6, the outer wall of the connecting pipe 2 53 is sleeved with a connecting ring, and the connecting ring is connected to the cylinder 54; the outer wall of the connecting pipe 1 52 is provided with a plurality of penetrating water cooling pipes 1 55, the outer wall of the connecting pipe 2 53 is provided with a plurality of penetrating water cooling pipes 2 56, the water cooling pipe 1 55 is plugged with the water cooling pipe 2 56, An inner tube 57 is provided on the inner wall of the water-cooling tube 1 55, a plurality of water outlet 1s 59 are provided on the side wall of the water-cooling tube 2 56, and a plurality of water outlet 2s 58 are provided on the side wall of the inner tube 57. When the water outlet 1 59 is aligned with the water outlet 2 58, cold water flows into the water-cooling tube 1 55 and the water-cooling tube 2 56. When the water outlet 1 59 is staggered with the water outlet 2 58, cold water flows into the water-cooling tube 1 55 or the water-cooling tube 2 56.

[0041] In a preferred embodiment, the inner wall of the water-cooling tube 1 55 is provided with a water outlet port 511, the outer wall of the water outlet port 511 is sleeved with an outer cylinder 512, the outer wall of the water outlet port 511 is provided with a guide block 513, the inner wall of the outer cylinder 512 is provided with an arc groove 514, the guide block 513 matches with the arc groove 514, when the guide block 513 is used with the arc groove 514, the outer cylinder 512 rotates, and the outer cylinder 512 is connected to the reset spring 515, the end of the water-cooling tube 2 56 is provided with a water inlet port 516, the water inlet port 516 is provided with a rotatably connected baffle 517, the baffle 517 is used to control the switch of the water inlet port 516, and the outer wall of the baffle 517 is provided with a connecting frame 518 matching with the outer cylinder 512.

[0042] In a preferred embodiment, water cooling tube one and water cooling tube two are respectively connected to discharge pipes, and water cooling tube one and water cooling tube two can be discharged from the discharge pipes when used separately, and the discharge pipe can be a hose to ensure that water cooling tube two can be moved.

[0043] Specifically, when water cooling is performed, cold water is transported to the connecting pipe 1 52, and the cold water in the connecting pipe 1 52 flows into the multiple water cooling pipes 1 55. At this time, the water outlet 1 59 on the water cooling pipe 1 55 is aligned with the water outlet 2 58, and the cold water can flow from the water cooling pipe 1 55 into the water cooling pipe 2 56. At this time, the entire cooling pipe 5 is filled with cold water, and the plant lamp is cooled at a high speed;

[0044] For example, when the cold water in the plant lamp one is transported to the plant lamp two, if one wants to ensure that the water flow speed in the plant lamp one remains unchanged and increase the water flow speed in the plant lamp two, the cylinder 54 can be used to drive the water cooling pipe two 56 in the plant lamp two to move, so that the water cooling pipe two 56 drives the water outlet two 58 on its outer wall to move, until the water outlet two 58 and the water outlet one 59 are completely misaligned. At this time, the water cooling pipe one 55 is isolated from the water cooling pipe two 56, and the water in the water cooling pipe one 55 cannot flow into the water cooling pipe two 56. After the flow area is reduced, the water flow speed in the plant lamp two becomes larger, and does not affect the flow speed in other adjacent plant lamps.

[0045] When the water-cooling pipe 55 is broken or cannot be used due to other unexpected circumstances, the cylinder 54 can be used to drive the water-cooling pipe 55 to move toward the water outlet port 511, and the water inlet port 516 can be fitted with the water outlet port 511. At this time, the connecting frame 518 on the baffle 517 fits with the outer cylinder 512, and the outer cylinder 512 can be driven to move on the water outlet port 511 by continuing to move. Since the arc groove 514 on the inner wall of the outer cylinder 512 fits with the guide block 513, the outer cylinder 512 can be used together to rotate when moving on the water outlet port 511, and the baffle 517 can be driven to rotate until the hole on the baffle 517 is aligned with the hole on the water inlet port 516. Then, the cold water flowing out of the water outlet port 511 can flow directly into the water inlet port 516, and finally into the water-cooling pipe 2 56, instead of flowing into the water-cooling pipe 1 55. Only the water-cooling pipe 2 56 is used to ensure that the cooling work is carried out smoothly.

[0049] In a preferred embodiment, the data acquisition module includes a lamp body temperature acquisition unit, a water temperature acquisition unit and a set temperature unit. The lamp body temperature acquisition unit is used to collect the temperature of the lamp body, the water temperature acquisition unit is used to collect the temperature of the water currently stored in the plant lamp, and the set temperature unit is used to set the temperature threshold of the plant lamp. When the current temperature of the plant lamp is higher than the temperature threshold, the plant lamp is water-cooled.

[0050] In a preferred embodiment, the flow path planning module comprises the following steps:

[0051] Step S1, obtaining the coordinate positions of several plant lamps, taking one plant lamp as a node, adding a connecting line between two connected plant lamps to form a connection topology diagram, marking the current temperature of each plant lamp, and marking the temperature threshold of each plant lamp;

[0052] Step S2, extract the plant lamps whose current temperature is higher than the temperature threshold, mark them as plant lamps to be cooled, mark the plant lamp with the lowest temperature among the plant lamps to be cooled, and use it as a first-level node. Take the first-level node as the starting point, and use the node directly connected to the first-level node as a second-level node, and mark all flow paths between the first-level node and the second-level node;

[0053] Step S3, extracting the current temperature of the plant lamp corresponding to the secondary node to form a secondary temperature set, extracting the secondary node corresponding to the lowest temperature in the secondary temperature set, and marking the flow path between the secondary node and the primary node as a primary flow path;

[0054] Step S4: transport the water in the plant lamp corresponding to the primary node to the plant lamp corresponding to the secondary node through the primary flow path, and calculate the temperature of the water flowing out of the plant lamp corresponding to the secondary node, and mark it as the predicted water temperature T out , the calculation formula is: T out =T in +μ(T source -T in ), where T out represents the outflowing water temperature, T in represents the temperature of the inflowing water, μ represents the exchange efficiency of the cooling tube 5, which can be obtained through historical data analysis, μ is 0.72, T sourceIndicates the temperature of the water flowing into the cooling tube 5 of the plant lamp; the calculated predicted water temperature is used as the current temperature of the plant lamp corresponding to the secondary node, the secondary node is used as the starting node, and steps S1 to S3 are repeated to output the secondary flow path until the preset water temperature in the plant lamp corresponding to the node is higher than the current temperature of the remaining plant lamps, then the node is used as the ending node, and all the output flow paths from the starting node to the ending node are obtained, and the flow path passing through the most nodes is output as the water-cooled flow path;
