Description

Technical Field

[0001] This invention relates to the field of poultry farming equipment technology, and more specifically, to a temperature control device for chicken houses. Background Technology

[0002] Maintaining a suitable temperature is crucial in poultry farming, especially during the winter when temperatures are low. Sealed chicken coops can lead to dampness, requiring ventilation by opening windows. However, this can cause the temperature inside the coop to drop further, making the chickens susceptible to illness. Therefore, it is necessary to use a temperature control device to raise the temperature of the chicken coop.

[0003] In existing technologies, chicken houses can be heated using heating devices such as heaters and radiators. However, heaters require high-powered fans to drive the hot air, which not only generates a lot of noise but also easily causes debris to fly around in the chicken house, affecting the environment. While hot water can be circulated in radiators for natural heat exchange, chicken houses are generally large and require multiple radiators. Consequently, the radiators near the water inlet have higher temperatures, while those further away have lower temperatures, leading to uneven temperatures and poor heating efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of poor heating effect of heat sinks in chicken coops, and to design a temperature control device for chicken coops.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a temperature control device for chicken coops, comprising multiple heat sinks connected by heat pipes, an insulating shell installed on the outside of the multiple heat sinks, multiple partitions installed inside the insulating shell, the partitions dividing the insulating shell into multiple insulating spaces, each insulating space containing a heat sink, a square opening at the top of the insulating space, an insulating shell installed inside the insulating space, the insulating shell enclosing the heat sink, an air outlet at the top of the insulating shell, an insulating curtain outside the air outlet, multiple sets of ventilation openings on the insulating curtain, each set of ventilation openings having a different length, a drive frame installed inside the insulating space, the drive frame driving the insulating curtain to move and causing different sets of ventilation openings to move above the air outlet.

[0006] Furthermore, the drive frame includes a first lifting block located on one side of the heat insulation shell, and a second lifting block located on the other side of the heat insulation shell. A counterweight is installed at the lower end of the second lifting block. One end of the heat insulation curtain is fixedly connected to the upper end of the first lifting block, and the other end of the heat insulation curtain is fixedly connected to the upper end of the second lifting block. Multiple guide holes are opened on the first and second lifting blocks, and guide rods are installed in the guide holes. The lower ends of the guide rods are installed inside the heat insulation shell. A counterweight box is installed at one end of the first lifting block, and a water pump is connected to the outside of the counterweight box. By changing the weight of the counterweight box, the second lifting block can move up and down. A limit frame is installed at one end of the second lifting block, and the limit frame can restrict the second lifting block to multiple different positions.

[0007] Furthermore, an air exchange valve is installed at the upper end of the counterweight box, a liquid level sensor is installed inside the counterweight box, and an infrared rangefinder is installed at the lower end of the counterweight box.

[0008] Furthermore, the water pump includes a water tank installed on the ground on one side of the insulation shell, a water pump installed on the lower side of the water tank, the inlet of the water pump being connected to the lower end of the water tank via a connecting pipe, a drain pipe installed at the outlet of the water pump, multiple solenoid valves installed on the drain pipe, a flexible pipe installed at the outlet of the solenoid valves, and one side of the flexible pipe passing through the insulation shell and extending into the lower side of the counterweight box.

[0009] Furthermore, the limiting frame includes multiple U-shaped fixing blocks installed on one side of the second lifting block. The inner side of the U-shaped fixing block is provided with a triangular prism, and the upper end of the triangular prism has a round hole. A rotating rod is provided in the round hole, and guide blocks are installed at both ends of the rotating rod. Guide grooves are opened on both sides of the U-shaped fixing block. One end of the guide block is located in the guide groove. One side surface of the guide block and one side surface of the guide groove are connected by a telescopic spring. Limiting plates are provided on both sides below the triangular prism and installed on the inner surface of the U-shaped fixing block. The right angle side of the triangular prism rests on the limiting plate. Multiple sets of limiting wheels are provided on one side of the second lifting block and installed on the inner surface of the insulation shell. The limiting wheels can contact the inclined surface of the triangular prism.

[0010] Furthermore, a support block is installed on the inner side of the U-shaped fixing block.

[0011] Furthermore, multiple sets of the limiting wheels are longitudinally distributed on the inner surface of the heat insulation shell, with each set having a different number of limiting wheels, and the upper limiting wheels having more than the lower limiting wheels.

[0012] Furthermore, multiple weight-adding blocks are provided on both sides of the second lifting block, and the multiple weight-adding blocks are longitudinally distributed. Limiting holes are opened on both sides of the weight-adding blocks, and limiting rods are provided in the limiting holes. The two ends of the limiting rods are connected to the inner surface of the insulation shell. Interception plates are installed on both sides of the weight-adding blocks. Multiple interception rods installed on the inner surface of the insulation shell are provided above both sides of the second lifting block. The interception rods correspond one-to-one with the weight-adding blocks, and the interception rods can intercept the interception plates.

[0013] Furthermore, the lengths of the multiple intercepting bars are different, with the intercepting bars at higher positions being longer, and the intercepting plate on the lower weight-adding block being closer to the second lifting block than the intercepting plate on the upper weight-adding block.

[0014] Furthermore, rotating rollers are installed on both sides of the upper end of the heat insulation shell, which can support the heat insulation curtain.

[0015] The beneficial effects of this invention are as follows: By wrapping the heat sink with an insulating shell and a heat insulation shell, direct heat leakage can be prevented. By placing a heat insulation curtain at the air outlet, the heat in the heat-insulating space can be discharged through the vent, thereby raising the temperature of the chicken house. By changing the size of the vent above the heat insulation curtain at different positions, the vent above the heat sink near the water inlet is smaller, and the vent above the heat sink away from the water inlet is larger. This results in less heat leakage from the heat sink with higher temperature and more heat leakage from the heat sink with lower temperature, making the overall temperature in the chicken house more balanced and improving the heating effect. Furthermore, it eliminates the need for a fan to drive air circulation, reducing noise and ensuring a good environment inside the chicken house. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This invention provides, for example Figure 1-11The temperature control device for chicken coop shown includes multiple heat sinks 1 connected by heat pipes 2. An insulating shell 3 is installed on the outside of each heat sink 1. Multiple partitions 4 are installed inside the insulating shell 3, dividing the insulating shell 3 into multiple insulating spaces 5. Each insulating space 5 contains one heat sink 1. A square opening 6 is provided at the top of each insulating space 5. An insulating shell 7 is installed inside each insulating space 5, enclosing the heat sink 1. An air outlet 8 is provided at the top of the insulating shell 7. An insulating curtain 9 is provided outside the air outlet 8. Multiple sets of ventilation openings 10 are provided on the insulating curtain 9, each set of ventilation openings 10 having a different length. A drive frame 11 is installed inside each insulating space 5, which can move the insulating curtain 9 and cause the different sets of ventilation openings 10 to move above the air outlet 8.

[0020] The process of heating the chicken coop using this device is as follows: The heat-conducting liquid flows in from the inlet of the first heat sink 1, and through the heat-conducting pipe 2, it flows sequentially to the subsequent heat sinks 1 and exits from the last heat sink 1. After reheating the heat-conducting liquid, it flows back in from the inlet of the first heat sink 1, allowing for its recycling. Under normal conditions, the insulation shell 3 and the heat-insulating shell 7 prevent a large amount of heat from dissipating to the outside of the heat sinks 1, allowing hot air to flow upwards. The hot air in the insulation space 5 flows outwards through the vent 10, the outlet 8, and the square opening 6, allowing outside air to flow into the insulation space 5, thus achieving heat exchange and heating the chicken coop. This is achieved through the drive frame 11. The moving heat insulation curtain 9 causes the air vents 10 on the heat insulation curtain 9 to move, and the opening of the air vent 10 above the first heat sink 1 is smaller. At this time, less heat is emitted to the outside of the heat insulation shell 3. The opening of the air vent 10 above the heat sink 1 further back is larger, which allows more heat to be emitted to the outside of the heat insulation shell 3. Since the temperature of the heat sink 1 at the front is higher, the temperature of its heat is also higher, but it emits less heat. The temperature of the heat sink 1 at the rear is relatively lower, and the temperature of its heat is also lower, but it emits more heat. This achieves a balance, so that the overall heat emitted to the outside of the heat insulation shell 3 by all the heat sinks 1 is roughly the same, which facilitates the even heating of the chicken house and ensures the heating effect.

[0021] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2The drive frame 11 includes a first lifting block 12 located on one side of the heat insulation shell 7, and a second lifting block 13 located on the other side of the heat insulation shell 7. A counterweight 14 is installed at the lower end of the second lifting block 13. One end of the heat insulation curtain 9 is fixedly connected to the upper end of the first lifting block 12, and the other end of the heat insulation curtain 9 is fixedly connected to the upper end of the second lifting block 13. Multiple guide holes 15 are opened on the first lifting block 12 and the second lifting block 13. A guide rod 16 is provided in the guide hole 15. The lower end of the guide rod 16 is installed inside the heat insulation shell 3. A counterweight box 17 is installed at one end of the first lifting block 12. A water pump 18 is connected to the outside of the counterweight box 17. By changing the weight of the counterweight box 17, the second lifting block 13 can move up and down. A limit frame 19 is installed at one end of the second lifting block 13. The limit frame 19 can limit the second lifting block 13 to multiple different positions.

[0022] The process of the drive frame 11 moving the heat insulation curtain 9 is as follows: Under normal conditions, the second lifting block 13 can be limited by the limiting frame 19, allowing the second lifting block 13 to stop moving at a certain height. When it is necessary to move the heat insulation curtain 9, heat-conducting liquid is added to the counterweight box 17 by the pump 18, which increases the weight of the counterweight box 17. Under the action of gravity, the counterweight box 17 can overcome the resistance of the limiting frame 19 on the second lifting block 13, causing the first lifting block 12 to move downward and the second lifting block 13 to move upward, thereby changing the position of the heat insulation curtain 9. At this time, the second position of the second lifting block 13 is limited by the limiting frame 19, and then the heat insulation curtain 9 can be limited. When it is necessary to move the heat insulation curtain 9 again... When the heat insulation curtain 9 moves, heat-conducting liquid can be added to the counterweight box 17 again to overcome the resistance of the limiting frame 19 to the second lifting block 13 in the second position, thereby allowing the second lifting block 13 and the heat insulation curtain 9 to move. When it is necessary to move the heat insulation curtain 9 in the opposite direction, the water in the counterweight box 17 can be pumped out by the water pump 18, thereby reducing the weight of the counterweight box 17. Then, under the gravity of the counterweight block 14, the second lifting block 13 can be pulled downward, causing the first lifting block 12 to move upward. Then, the limiting frame 19 limits the second lifting block 13, thereby facilitating the adjustment of the position of the heat insulation curtain 9. The guide hole 15 and the guide rod 16 can ensure the moving direction of the first lifting block 12 and the second lifting block 13.

[0023] Refer to the instruction manual appendix Figure 1 A ventilation valve 20 is installed at the upper end of the counterweight box 17, a liquid level sensor 21 is installed inside the counterweight box 17, and an infrared rangefinder 22 is installed at the lower end of the counterweight box 17. The ventilation valve 20 allows air to circulate inside the counterweight box 17, which facilitates the addition and removal of heat-conducting liquid. The liquid level sensor 21 can detect the liquid level height inside the counterweight box 17, which can facilitate the sending of signals to control the operation of the water pump 18. The infrared rangefinder 22 can detect the height of the counterweight box 17, which can facilitate ensuring the positional accuracy of the heat insulation curtain 9.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Included with instruction manual Figure 7 The water pump 18 includes a water tank 23 installed on the ground on one side of the insulation shell 3. A water pump 24 is installed on the lower side of the water tank 23. The inlet of the water pump 24 is connected to the lower end of the water tank 23 through a connecting pipe 25. A drain pipe 26 is installed at the outlet of the water pump 24. Multiple solenoid valves 27 are installed on the drain pipe 26. A flexible pipe 28 is installed at the outlet of the solenoid valves 27. One side of the flexible pipe 28 passes through the insulation shell 3 and extends into the lower side of the counterweight box 17.

[0025] The process of pumping heat-conducting liquid by the pump 18 is as follows: When it is necessary to increase the weight of a certain counterweight box 17, the corresponding solenoid valve 27 is opened and the pump 24 is started, which can then pump the heat-conducting liquid in the water tank 23 into the counterweight box 17, and then the counterweight box 17 can move downward. When it is necessary to decrease the weight of a certain counterweight box 17, the corresponding solenoid valve 27 is opened and the pump 24 is started, which can then pump the heat-conducting liquid in the counterweight box 17 into the water tank 23, and then the counterweight box 17 can move upward.

[0026] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 8 The limiting frame 19 includes multiple U-shaped fixing blocks 29 installed on one side of the second lifting block 13. A triangular prism 30 is provided on the inner side of the U-shaped fixing block 29. A round hole 31 is opened at the upper end of the triangular prism 30. A rotating rod 32 is provided in the round hole 31. Guide blocks 33 are installed at both ends of the rotating rod 32. Guide grooves 34 are opened on both sides of the U-shaped fixing block 29. One end of the guide block 33 is located in the guide groove 34. One side surface of the guide block 33 and one side surface of the guide groove 34 are connected by a telescopic spring 35. Limiting plates 36 are provided on both sides below the triangular prism 30 and installed on the inner surface of the U-shaped fixing block 29. The right angle side of the triangular prism 30 falls on the limiting plate 36. Multiple sets of limiting wheels 37 are provided on one side of the second lifting block 13 and installed on the inner surface of the heat insulation shell 3. The limiting wheels 37 can contact the inclined surface of the triangular prism 30.

[0027] The limiting mechanism 19 limits the second lifting block 13 as follows: Under normal conditions, when the weight of the first lifting block 12 is greater than the weight of the second lifting block 13, the first lifting block 12 moves downward, causing the second lifting block 13 to move upward. When the U-shaped fixing block 29 on the second lifting block 13 moves to one side of the limiting wheel 37, the limiting wheel 37 contacts the inclined surface of the triangular prism 30, thereby generating resistance and stopping the second lifting block 13 from moving. The limiting plate 36 can support the lower end of the triangular prism 30 to prevent it from rotating. When it is necessary to change the position of the heat insulation curtain 9, the weight on one side of the first lifting block 12 increases, causing the second lifting block 13 to move upward. The limiting wheel 37 can push the triangular prism 30 to one side. The guide block 33 and the guide groove 34 can keep the weight of the first lifting block 12 increased, causing the second lifting block 13 to move upward. The limiting wheel 37 can push the triangular prism 30 to one side. The direction of movement of the triangular prism 30 is determined, and the telescopic spring 35 is compressed, which allows the triangular prism 30 to avoid the limiting wheel 37 and the second lifting block 13 to move to the limiting wheel 37 on the next layer. Then, under the elastic force of the telescopic spring 35, the triangular prism 30 returns to its original position. When the weight on one side of the first lifting block 12 decreases, the second lifting block 13 can move downward. When the straight surface of the lower end of the triangular prism 30 falls on the limiting wheel 37, the triangular prism 30 can rotate around the rotating rod 32 under the action of gravity, thus avoiding the limiting wheel 37. After the triangular prism 30 moves below the limiting wheel 37, since the center of gravity is at the upper end and the straight surface of the triangular prism 30 is heavier, the triangular prism 30 can rotate back to its original position under the action of gravity and be supported by the limiting plate 36.

[0028] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A support block 38 is installed on the inner side of the U-shaped fixing block 29. The support block 38 can support the triangular prism 30 and prevent the triangular prism 30 from rotating too much and failing to return to its original position.

[0029] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 Multiple sets of limiting wheels 37 are longitudinally distributed on the inner surface of the heat insulation shell 3. The number of limiting wheels 37 in each set is different, with the number of upper limiting wheels 37 being greater than the number of lower limiting wheels 37. By increasing the number of limiting wheels 37, the resistance encountered by the second lifting block 13 when it moves up one layer is greater, preventing the second lifting block 13 from going directly to the top.

[0030] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 10 Included with instruction manual Figure 11The second lifting block 13 has multiple weight-adding blocks 39 on both sides, which are longitudinally distributed. Limiting holes 40 are opened on both sides of each weight-adding block 39, and limiting rods 41 are installed within the limiting holes 40. The two ends of the limiting rods 41 are connected to the inner surface of the insulation shell 3. Interception plates 42 are installed on both sides of the weight-adding blocks 39. Multiple intercepting rods 43 are installed on the inner surface of the insulation shell 3 above both sides of the second lifting block 13. Each intercepting rod 43 corresponds to a weight-adding block 39, and can intercept the intercepting plates 42. As the second lifting block 13 moves upwards, the weight-adding blocks above it can be increased. Adding a weight-increasing block 39 increases the weight on one side of the second lifting block 13. When the second lifting block 13 needs to be moved downward, it is not necessary to completely drain the heat-conducting liquid in the counterweight box 17. This allows the weight on one side of the second lifting block 13 to exceed the weight on one side of the first lifting block 12, thus facilitating the downward movement of the second lifting block 13. The limiting hole 40 and the limiting rod 41 can be positioned in the direction of movement of the weight-increasing block 39. The intercepting rod 43 can intercept the intercepting plate 42, thereby stopping the weight-increasing block 39 at a specified position. This facilitates changing the weight on one side of the second lifting block 13.

[0031] Refer to the instruction manual appendix Figure 10 The multiple intercepting bars 43 have different lengths, with the higher the position of the intercepting bar 43, the longer it is. The intercepting plate 42 on the lower weight-adding block 39 is closer to the second lifting block 13 than the intercepting plate 42 on the upper weight-adding block 39, which makes it easier to intercept the corresponding weight-adding block 39 through the designated intercepting bar 43, thus ensuring the position of the weight-adding block 39.

[0032] Refer to the instruction manual appendix Figure 1 Rotating rollers 44 are installed on both sides of the upper end of the heat insulation shell 7. The rotating rollers 44 can support the heat insulation curtain 9 and reduce the friction when the heat insulation curtain 9 moves.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
