Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a novel air conditioner for agricultural and engineering machinery based on photovoltaic panels. Background Technology

[0002] Agricultural machinery is mostly self-propelled power machines used to traction and drive other machinery to complete various mobile operations, and it plays an irreplaceable role in modern agricultural production.

[0003] Currently, temperature control in agricultural machinery (such as tractors and combine harvesters) typically relies on traditional air conditioning systems. However, due to the relatively small space in agricultural machinery cabs and the need to adjust the temperature according to different climatic conditions and working environments, the applicability of traditional air conditioning in such applications is limited. Furthermore, the diverse spatial layout and temperature control requirements within agricultural machinery cabs also make standard air conditioning systems inflexible in practical applications, making it difficult to meet precise temperature regulation needs.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a novel air conditioner for agricultural and engineering machinery based on photovoltaic panels.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a novel air conditioner for agricultural and engineering machinery based on photovoltaic panels, comprising a canopy adapted and installed on the machine's cab, the canopy being composed of an outer canopy and an inner canopy stacked together, with a plurality of air outlets on one side of the inner canopy for introducing hot or cold air into the machine's cab, and a novel air conditioner body correspondingly provided on the air outlets for raising or lowering the temperature inside the machine's cab, the novel air conditioner body comprising:

[0007] An air outlet panel is correspondingly located at the air outlet.

[0008] The thermoelectric module is located inside the air outlet panel and is composed of multiple thermoelectric materials. The outside of the thermoelectric module is provided with a heat insulation cavity to prevent heat from being conducted from the hot side to the cold side. Multiple small circuits are arranged in series or parallel through multiple thermoelectric materials. When current passes through the circuits formed by the arrangement, a thermoelectric effect is generated, with one end absorbing heat and the other end releasing heat.

[0009] Two mounting mechanisms are symmetrically arranged on both sides of the outside of the air outlet, used to install and remove the air outlet panel at the opening position of the air outlet.

[0010] Furthermore, the installation mechanism includes a fixed end block fixed with screws to the upper end of the air outlet, a bidirectional lead screw rotatably disposed inside the fixed end block, two symmetrical movable blocks that are threadedly adapted to the bidirectional lead screw and limit horizontal movement on the bottom surface of the fixed end block, a rhomboid frame composed of four-sided support rods rotatably disposed between the two movable blocks, and a limiting plate rotatably disposed between the two oppositely distributed support rods for moving along the axial direction perpendicular to the bidirectional lead screw.

[0011] Furthermore, the air outlet panel is provided with a groove corresponding to the position of the fixed end block, and both sides of the groove are provided with limiting side grooves that pass through the limiting plate.

[0012] Furthermore, one end of the bidirectional lead screw is provided with a drive unit that drives the bidirectional lead screw to rotate;

[0013] The drive unit includes a gear sleeved on one end of the bidirectional lead screw and a rack that meshes with the gear and moves through a slot on the end face of the air outlet panel.

[0014] Furthermore, the end face of the air outlet panel is provided with several ventilation grooves at equal intervals, and a guide plate for guiding air and adjusting the air volume is rotatably arranged in each ventilation groove;

The cavity layer is also provided with a heat dissipation device for rapidly dissipating heat from the heat-dissipating surface of the thermoelectric module during cooling.

[0017] Furthermore, an inspection cover is provided on the outside of the cavity layer, and photovoltaic panels for photovoltaic power generation and splicing are provided on the outer surface of the inspection cover.

[0018] Compared with existing technologies, this utility model has the following beneficial effects: This utility model uses a novel air conditioning unit composed of an air outlet panel and a thermoelectric module. By replacing the compressor in a traditional air conditioner with a thermoelectric module, it can achieve cooling or heating modes by changing the direction of current flow, reducing the energy consumption required by traditional air conditioners and avoiding the use of refrigerants, thus avoiding negative environmental impacts. Furthermore, through the designed installation mechanism, one or more novel air conditioning units can be flexibly selected and installed according to the size and requirements of the machine cab, corresponding to the position and number of air outlets in the inner ceiling, to adapt to different space and temperature control needs, providing appropriate heating or cooling effects.

Detailed Implementation

[0030] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figure 1-9 As shown, this utility model discloses a novel air conditioner based on photovoltaic panels and applied to agricultural and construction machinery. It includes a canopy adapted for installation on the machine's cab. The canopy is composed of an outer canopy 100 and an inner canopy 101 stacked together. One side of the inner canopy 101 has several air outlets 102 for introducing hot or cold air into the machine's cab. Each air outlet 102 is equipped with a novel air conditioner body 200 for raising or lowering the temperature inside the machine's cab. The novel air conditioner body 200 includes:

[0032] An air outlet panel 1 is correspondingly disposed at the air outlet 102;

[0033] Thermoelectric module 2 is disposed inside the air outlet panel 1 and is composed of multiple thermoelectric materials. The outside of the thermoelectric module 2 is provided with a heat insulation cavity to prevent heat from being conducted from the hot side to the cold side. Multiple small circuits are arranged in series or parallel through multiple thermoelectric materials. When current passes through the circuits formed by the arrangement, a thermoelectric effect is generated, with one end absorbing heat and the other end releasing heat.

[0034] Two mounting mechanisms 3 are symmetrically arranged on both sides of the outside of the air outlet 102, and are used to install and remove the air outlet panel 1 at the opening position of the air outlet 102.

[0035] In specific implementation, a number of air outlets 102 that are slotted on one side of the inner ceiling 101 are used to allow air to enter, and an air outlet panel 1 that can be detachably assembled at the end of the air outlet 102, and a thermoelectric module 2 installed on the inner side of the air outlet panel 1, are used. It is a device that works based on the thermoelectric effect and achieves heat transfer through the action of current. It can be used for both cooling and heating, and is generally achieved by controlling and changing the direction of current.

[0036] Furthermore, the mounting mechanisms 3, which are symmetrically fixed on both sides of the air outlet 102, can be installed according to the installation position and number of the air outlet 102, to meet the cooling and heating needs of the machine cab, provide appropriate heating or cooling effects, and have universal applicability.

[0037] It should be noted that in thermoelectric module 2, the cold and hot sides are separated by a heat-insulating cavity, and forced convection is used in both cavities to improve heat exchange efficiency. Independent fans are typically installed on the cold and hot sides to increase airflow and enhance heat exchange.

[0038] It should be noted that the air guide opening on the side of the area separated by the heat insulation cavity and close to the air outlet panel 1 can also be connected to the air inlet opening on the ceiling. This will generate hot or cold air from the air inlet on the ceiling, which passes through the air guide opening and exits from the air outlet panel 1 under the action of the thermoelectric module 2.

[0039] It should be noted that thermoelectric module 2 is typically composed of two different semiconductor materials (P-type and N-type):

[0040] P-type semiconductors have a large number of holes as current carriers;

[0041] N-type semiconductors have a higher proportion of electrons as current carriers;

[0042] These P-type and N-type semiconductors are arranged alternately to form multiple "thermocouples". When current passes through, the contact points between the P-type and N-type materials will absorb and release heat respectively, thus producing cooling and heating effects.

[0043] In one embodiment, the installation mechanism 3 includes a fixed end block 31 fixed with screws to the upper end of the air outlet 102, and a bidirectional lead screw 32 rotatably disposed inside the fixed end block 31. The bidirectional lead screw 32 is threadedly fitted with two symmetrical movable blocks 33 that are limited to horizontal movement on the bottom surface of the fixed end block 31. A rhomboid frame 34 composed of four-sided support rods is rotatably disposed between the two movable blocks 33. A limiting plate 35 for moving along the axial direction perpendicular to the bidirectional lead screw 32 is rotatably disposed between the two oppositely distributed support rods. With this design, the fixed end block 31, which is fixedly installed on both sides of the air outlet 102 with screws, and the bidirectional lead screw 32, which is rotatably installed with slots on the end face of the fixed end block 31, will cause the two movable blocks 33, which are threadedly fitted on the fixed end block 31, to move towards each other under the limit of the inner bottom surface of the fixed end block 31. This will cause the rhomboid frame 34, which is rotatably installed between the two movable blocks 33, to compress towards each other, so that the two relatively rotating limit plates 35 on the rhomboid frame 34 will move outward along the axial direction of the bidirectional lead screw 32.

[0044] It should be noted that the two sides of the fixed end block 31 have through slotted openings that can accommodate the limiting plate 35 so that the limiting plate 35 can pass through and move to the outside of the fixed end block 31.

[0045] It should be noted that the double-acting lead screw 32 has two sections with opposite thread directions.

[0046] In one embodiment, a groove 4 is adapted to the position of the fixed end block 31 on the air outlet panel 1, and a limiting side groove 41 for the limiting plate 35 is provided through both sides of the groove 4. With this design, the groove 4 is opened by turning the installation size of the fixed end block 31 on the air outlet panel 1, and the limiting side grooves 41 for the movement of the limiting plate 35 are machined through both sides of the groove 4. When the limiting plate 35 moves to the limiting side groove 41 under the action of external force, the limiting plate 35 will fit and overlap in the limiting side groove 41, so that the air outlet panel 1 is fixed to the air outlet 102 by the mounting mechanism 3.

[0047] In one embodiment, a drive unit is provided at one end of the bidirectional lead screw 32 to drive the bidirectional lead screw 32 to rotate;

[0048] The drive unit includes a gear 36 sleeved on one end of the bidirectional lead screw 32 and a rack 37 meshing with the gear 36 and moving through a slot on the end face of the air outlet panel 1. This design allows the gear 36 on one end of the bidirectional lead screw 32 and the rack 37, which moves through a slot on the end face of the air outlet panel 1 and meshes with the gear 36, to transmit force and drive the bidirectional lead screw 32 to rotate when the rack 37 moves. This facilitates the easy installation and removal of the air outlet panel 1.

[0049] In one embodiment, the end face of the air outlet panel 1 is provided with a plurality of ventilation grooves 5 at equal intervals, and a guide plate 6 for guiding air and adjusting the air volume is rotatably disposed in each ventilation groove 5;

[0050] The guide plate 6 consists of a straight plate rotatably disposed within the ventilation slots 5 and two arc plates symmetrically welded to the outer ends of the straight plate. This design, through the equidistant machining of several ventilation slots 5 on the end face of the air outlet panel 1, and the guide plate 6 rotatably installed in the center of each ventilation slot 5, allows the area within the correspondingly separated ventilation slots 5 to decrease and the area within the disjointed ventilation slots 5 to increase when the guide plate 6 is rotated in one direction. This increases the air volume and achieves air volume regulation. Simultaneously, the arc plate structure formed on the guide plate 6 facilitates airflow, improving cooling and heating performance.

[0051] It should be noted that, as Figure 4 As shown, the guide plate 6 is composed of a straight plate and two arc plates welded together.

[0052] In one embodiment, the outer ceiling 100 is provided with a cavity layer that communicates with the insulation cavity and provides heat insulation to the heat-absorbing surface of the thermoelectric module 2 during heating. The cavity layer is also provided with a heat dissipation device for rapidly dissipating heat from the heat-dissipating surface of the thermoelectric module 2 during cooling. This design, through the cavity layer within the outer ceiling 100 and the interlayer between the outer ceiling 100 and the inner ceiling 101, and the insulation cotton adhered to the inner wall of the cavity layer, ensures that the heat-absorbing surface of the thermoelectric module 2 prevents external heat from entering during heating, maintaining a lower temperature for the cold surface and avoiding the influence of external heat sources.

[0053] By installing heat dissipation equipment inside the cavity layer, when the thermoelectric module 2 is cooling, the outer area of ​​its heat-dissipating surface will help the hot surface dissipate heat under the action of the heat dissipation equipment, increasing air flow and promoting heat dissipation, thereby improving the cooling performance of the thermoelectric module 2.

[0054] It should be noted that the air inlets on the outer sides of the outer canopy 100, which are machined and connected to the cavity layer, are opened when dissipating heat from the hot surface and closed when insulating the cold surface.

[0055] It should be noted that the heat dissipation equipment adopts a structure including but not limited to a fan.

[0056] In one embodiment, an inspection cover 7 is provided on the outside of the cavity layer, and photovoltaic panels 8 for photovoltaic power generation and modular assembly are provided on the outer surface of the inspection cover 7. This design allows the inspection cover 7, which is hinged and installed on the outer roof 100, to be flipped open for periodic maintenance of the equipment structure assembled inside the cavity layer between the outer roof 100 and the inner roof 101.

[0057] The photovoltaic panels 8, which are assembled on the outer surface of the inspection cover 7, can be divided into multiple modules. Each module is fixed to the outside of the inspection cover 7 by an independent bracket, which makes it convenient to carry out independent inspection and maintenance of a certain part.

[0058] It should be noted that the photovoltaic panel 8 needs to be equipped with, but is not limited to, an inverter and a battery, and the equipped equipment structure is installed in the cavity layer.

[0059] It should be noted that auxiliary power can also be provided by the engines of agricultural and construction machinery.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0061] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0062] Furthermore, "several" and "a number" both refer to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
