Description

Technical Field

[0001] This utility model relates to the field of flower cultivation, and in particular to a temperature control device for a flower cultivation greenhouse. Background Technology

[0002] In the process of flower cultivation, the temperature stability of the greenhouse directly affects the growth cycle and quality of flowers. Especially for varieties with different temperature requirements, such as tropical flowers and temperate flowers, precise temperature control has become a core technical requirement.

[0003] Patent CN221264606U discloses an intelligent temperature control device for greenhouses, including a fan, a right pipe, a left pipe, a heating pipe, and a telescopic duct. The fan is equipped with a thermostat and a temperature sensor. The right pipe is fixedly connected to the right side of the fan via fasteners, and the left pipe is fixedly connected to the left side of the fan via fasteners. The left pipe has an insertion hole, and the heating pipe is inserted through the left side of the left pipe. Fastening rods are threaded to both the front and rear ends of the heating pipe. An electric heater is installed on the inner wall of the heating pipe. The telescopic duct is located to the left of the heating pipe. In this invention, the fastening rods can rotate outwards. When the fastening rods disengage from the insertion hole of the left pipe, the heating pipe can be directly moved away from the left pipe, achieving quick disassembly for maintenance and cleaning of the electric heater. Simultaneously, the telescopic duct is flexible and extendable to adjust the position and height of the air vents.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] The telescopic duct of this device can only change the air supply range by adjusting the direction of the air outlet, which cannot target the problem of local overheating of the planting rack. It requires air supply to the whole area, which can easily cause low temperature stress in non-overheated areas. There is no local spray structure, and adjusting some overheated areas requires the energy consumption of cooling the whole greenhouse. Watering the whole area can also easily cause gray mold. In addition, the patent does not integrate diseased leaf detection and pruning functions, which requires manual inspection and independent pruning equipment. It is difficult for manuals to capture diseased leaves and yellow leaves under high temperature in real time, and multi-layer planting racks are prone to missed detection. The independent equipment takes up space and cannot be linked with temperature control, which prolongs the disease transmission window and reduces the yield of flowers. Therefore, this utility model proposes a temperature control device for flower planting greenhouse. Utility Model Content

[0006] The main purpose of this invention is to provide a temperature control device for flower planting greenhouses, which can effectively solve the problems in the background technology.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This device: A first motor drives four planting racks to rotate synchronously, ensuring the flowers receive heat evenly from the electric heating elements and preventing uneven heating in certain areas. When some flowers become too hot, the annular outer shell can precisely move to the target area, using a combination of physical shielding of the electric heating elements and localized spray cooling.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1 - Figure 7 The device shown is a temperature control device for a flower cultivation greenhouse, including a base 1. Four planting racks 2 are rotatably connected to the upper end of the base 1. A first motor 3 is installed on the inner side of the base 1. The output shaft of the first motor 3 is fixedly connected to one of the four planting racks 2. Sprockets 4 are fixedly connected to the outer side of each planting rack 2. A chain 5 is meshed with the outer side of the sprockets 4. Four symmetrical electric heating elements 6 are fixedly connected to the outer side of the base 1. A cooling mechanism 7 for cooling the flowers is installed at the upper end of the base 1.

[0027] In this embodiment, the cooling mechanism 7 includes four second motors 71 installed inside the base 1. The output shafts of the second motors 71 are all fixedly connected to threaded rods 72. The outer side of the threaded rods 72 is threadedly connected to an L-shaped tube 73. One end of the L-shaped tube 73 is slidably connected to a slide rod 74 via a slider. The other end of the L-shaped tube 73 is fixedly connected to an annular outer shell 75 via a fixing sleeve.

[0028] Specifically, the second motor 71 provides the power source for the movement of the cooling mechanism 7, and its output shaft can drive the threaded rod 72 to rotate around its own axis; the threaded rod 72 converts its rotational motion into the linear motion of the L-shaped tube 73 through the threaded engagement with the L-shaped tube 73; the slide rod 74 guides and limits the movement of the L-shaped tube 73 through the slider, preventing the L-shaped tube 73 from rotating synchronously with the threaded rod 72, and ensuring that the L-shaped tube 73 slides smoothly along a fixed trajectory; the L-shaped tube 73 serves as a connecting carrier, with one end engaging with the threaded rod 72 and the slide rod 74 to achieve movement, and the other end driving the annular outer shell 75 to move synchronously through the fixed sleeve, so that the annular outer shell 75 can accurately reach the flower area that needs cooling.

[0029] In this embodiment, a sensor is provided at the lower end of the annular housing 75, a spray head is provided on the inner side of the annular housing 75, a water pipe 76 is fixedly connected to the upper end of the annular housing 75, a solenoid valve 77 is provided on the outer side of the water pipe 76, a water tank 78 is fixedly connected to the other end of the water pipe 76, a mounting plate 79 is fixedly connected to the lower end of the water tank 78, and the lower end of the mounting plate 79 is fixedly connected to the L-shaped pipe 73 through a fixing sleeve.

[0030] Specifically, the sensor at the lower end of the annular housing 75 is used to detect the temperature of the flower area below in real time. When the temperature is detected to be too high, it can trigger a cooling action. The spray head inside is the cooling execution component, which can spray water evenly onto the surface of the flowers. The water pipe 76 is a water supply channel to realize the water transfer between the water tank 78 and the annular housing 75. The solenoid valve 77 is used to control the opening and closing of the water pipe 76, and accurately starts and stops the water supply according to the temperature sensor signal. The water tank 78 serves as a water storage component to provide water for the spray cooling. The mounting plate 79 fixes the water tank 78 to the L-shaped pipe 73 through a fixing sleeve to ensure that the water tank 78 moves synchronously with the L-shaped pipe 73, and avoids damage to the water pipe 76 due to relative displacement.

[0031] In this embodiment, a fixing ring 710 is fixedly connected to the lower end of the annular outer shell 75, and an internal gear ring 711 is fixedly connected to the lower end of the fixing ring 710. A gear 712 is meshed with the inner side of the internal gear ring 711, and a sliding frame 713 is rotatably connected to the outer side of the gear 712. A sensor is provided on the inner side of the sliding frame 713, and the outer side of the sliding frame 713 is slidably connected to the fixing ring 710 through a slider.

[0032] Specifically, one end of the fixed ring 710 is fixed to the annular housing 75 and moves synchronously with the annular housing 75, while the other end provides installation and movement support for the internal gear ring 711 and the sliding frame 713. The internal gear ring 711 meshes with the gear 712, providing a transmission basis for the circular motion of the sliding frame 713. The gear 712 converts its rotational motion into the circular motion of the sliding frame 713 through meshing with the internal gear ring 711. The sliding frame 713 cooperates with the fixed ring 710 through the outer slider, and can slide smoothly along the annular trajectory of the fixed ring 710. The sensor on its inner side is used to detect the condition of the flower leaves and identify abnormal conditions such as diseased leaves and yellow leaves.

[0033] In this embodiment, a third motor 714 is installed at the lower end of the sliding frame 713. The output shaft of the third motor 714 is fixedly connected to the gear 712 via a rotating shaft. The lower end of the sliding frame 713 is fitted with the housing of the first electric telescopic rod 715 via a fixing plate. The output shaft of the first electric telescopic rod 715 is fixedly connected to the housing of the second electric telescopic rod 716 via a coupling. The output shaft of the second electric telescopic rod 716 is fixedly connected to a bracket 717. The inner side of the bracket 717 is rotatably connected to two symmetrical connecting rods 718 via a rotating shaft.

[0034] Specifically, the third motor 714 provides power for the rotation of the gear 712, and its output shaft drives the gear 712 to rotate around its own axis through a rotating shaft, thereby driving the sliding frame 713 to move; the first electric telescopic rod 715 is fixed to the fixed plate at the lower end of the sliding frame 713 through the outer shell, and its output shaft can drive the second electric telescopic rod 716 to move in the horizontal direction, adjusting the horizontal distance between the shearing component and the flower leaves; the output shaft of the second electric telescopic rod 716 drives the bracket 717 to move in the vertical direction, controlling the lifting and lowering of the shearing component; the bracket 717 is connected to the connecting rod 718 through a rotating shaft, which can convert the linear motion of the second electric telescopic rod 716 into the rotation of the connecting rod 718, providing power transmission for the action of the shearing blade 719.

[0035] In this embodiment, the two connecting rods 718 are rotatably connected to the shearing blades 719 on their adjacent sides via a pivot. The inner sides of the two shearing blades 719 are rotatably connected to a fixing rod 720. The upper and lower ends of the fixing rod 720 are fixedly connected to a mounting bracket 721. The inner side of the mounting bracket 721 is fixedly connected to the outer shell of the second electric telescopic rod 716.

[0036] Specifically, the connecting rod 718 rotates around the pivot under the drive of the bracket 717, and then drives the shearing blade 719 to open and close. The shearing blade 719 is the pruning execution component. By closing the two shearing blades 719, diseased leaves and yellow leaves can be cut off. The fixing rod 720 passes through the inside of the two shearing blades 719, providing a fulcrum for the rotation of the shearing blades 719 and ensuring the stability of the opening and closing trajectory of the shearing blades 719. The mounting bracket 721 is fixed to the housing of the second electric telescopic rod 716, positioning the fixing rod 720 so that the shearing blades 719 only perform opening and closing movements under the drive of the connecting rod 718, ensuring the accuracy of pruning.

[0037] Working principle: When the equipment is in use, the first motor 3 is started, and its output shaft drives a planting frame 2 to rotate. The planting frame 2 drives the corresponding sprocket 4 to rotate. The sprocket 4 drives the other three sprockets 4 and the corresponding planting frame 2 to rotate synchronously through the chain 5. At the same time, the electric heating element 6 is started to heat the flowers.

[0038] When some flowers are too hot, the sensor at the lower end of the annular housing 75 receives a signal, and the system will start the corresponding second motor 71. The output shaft of the second motor 71 drives the threaded rod 72 to rotate, and the threaded rod 72 drives the L-shaped tube 73 to slide along the outside of the slide rod 74, thereby moving the annular housing 75 to the outside of the flowers that need to be cooled. On the one hand, the annular housing 75 blocks the high temperature of the electric heating element 6 from the outside. On the other hand, the system activates the solenoid valve 77 to transport water from the water tank 78 to the inside of the annular housing 75 through the water pipe 76, and then sprays the water onto the surface of the flowers from the spray head inside the annular housing 75 to achieve cooling.

[0039] Simultaneously, as the annular outer shell 75 moves, it drives the fixed ring 710 to move synchronously. The system starts the third motor 714, whose output shaft drives the gear 712 to rotate through the rotating shaft. The gear 712 meshes with the internal gear ring 711, thereby driving the sliding frame 713 to rotate along the trajectory of the fixed ring 710. When some flowers develop diseased or yellow leaves, the sensor inside the sliding frame 713 receives the signal and first drives the first electric telescopic rod 715 to adjust the horizontal position of the second electric telescopic rod 716 so that the shearing blade 719 is aligned with the diseased leaf. Then, it drives the second electric telescopic rod 716, whose output shaft drives the bracket 717 to move vertically. The bracket 717 pushes the connecting rod 718 to rotate around the fixed rod 720 through the rotating shaft. Under the limiting action of the fixed rod 720 and the mounting frame 721, the connecting rod 718 drives the shearing blade 719 to close through the rotating shaft, pruning the diseased and yellow leaves.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
