Description

Technical Field

[0001] This utility model relates to the technical field of soil temperature regulation equipment, specifically to a soil warming device that uses a warming pipe installed at a 45-degree angle. Background Technology

[0002] In the field of soil temperature regulation equipment technology, in order to study ecological processes such as plant community photosynthesis, community respiration, or ground-level greenhouse gas emission fluxes, it is often necessary to change the soil temperature of sample plots to observe the ecological responses under different temperature conditions. Changes in soil temperature have a significant impact on plant root growth, the activity of bacteria and microorganisms in the soil, and these impacts can lead to changes in plant community respiration, photosynthesis, or ground-level greenhouse gas emission fluxes.

[0003] Currently, similar instruments and equipment used to increase soil temperature mainly employ the following three methods:

[0004] Infrared electric heater heating: High-power infrared electric heaters are used above the sample plot to provide energy to the ground through infrared radiation to increase the surface soil temperature. However, this method is inefficient, most of the heat is absorbed by the ground plants, which can easily burn the plant leaves, and the heating effect is uneven.

[0005] Soil heating cables: Soil heating cables can be used to heat the soil, specifically the surface layer. However, when the cables are manually buried deep in the soil, it causes significant disturbance, damages the soil structure, and affects the accuracy of the experiment.

[0006] Vertically buried heating pipes: These pipes are used to heat the soil. The traditional method involves vertically driving the heating pipes into the soil to a certain depth around the sample plot. This method has a significant drawback: the temperature distribution is uneven between the periphery and the center of the sample plot, affecting the overall experimental results and potentially leading to erroneous conclusions.

[0007] In summary, existing soil warming equipment has shortcomings in terms of heating efficiency, damage to soil structure, and uniformity of temperature distribution. Therefore, there is an urgent need for a soil warming device that can efficiently and uniformly heat the soil while avoiding damage to its structure. Utility Model Content

[0008] The purpose of this invention is to provide a soil heating device that uses a heating tube installed at a 45-degree angle to solve the problems of existing soil heating equipment mentioned in the background art in terms of heating efficiency, damage to soil structure, and uniformity of temperature field distribution.

[0009] To achieve the above objectives, this utility model provides a soil heating device with heating tubes installed at a 45-degree angle, including a soil container. Several heating tubes are installed inside the soil container at a 45-degree angle. The bottom of the heating tubes is supported and fixed by a support component, and the top of the heating tubes is connected to a temperature controller via wiring. The wiring at the top of the heating tubes is organized and positioned by a wiring tube.

[0010] Preferably, the heating tubes are arranged in a ring at equal intervals inside the soil container.

[0011] Preferably, a positioning sleeve is provided in the middle of the heating tube, and a positioning bolt is installed on the outside of the positioning sleeve. The heating tube slides with the positioning sleeve and is locked in place by the positioning bolt.

[0012] Preferably, the bottom end of the heating tube is provided with a pointed tip.

[0013] Preferably, the support assembly includes a fixing sleeve, a lifting rod is inserted into the top of the fixing sleeve, the top end of the lifting rod is connected and fixed to the positioning sleeve, and the bottom end of the fixing sleeve is connected and fixed to the bottom inner wall of the soil container.

[0014] Preferably, a height adjustment bolt is installed on the upper side of the fixed sleeve, and the lifting rod slides with the fixed sleeve and is locked and positioned by the height adjustment bolt.

[0015] Preferably, the cable management tube has a ring structure with several side openings on its outer wall, and several radial tubes are connected to the inner side of the cable management tube, with a central opening at the end of each radial tube.

[0016] Preferably, the side openings are arranged in a ring with equal spacing.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In this soil heating device that uses a 45-degree angle to install the heating pipe, the heating pipe is installed at a 45-degree angle in the soil container. This installation method allows the heat from the heating pipe to diffuse more effectively from the bottom of the soil upwards, improving heating efficiency. Compared to the traditional vertical burial method, the 45-degree angle installation can heat the soil more evenly and avoid localized heat accumulation in the soil.

[0019] The heating tubes are arranged in a ring at equal intervals inside the soil container, a layout that further ensures the uniformity of the soil temperature field. By adjusting the insertion depth and density of the heating tubes, the distribution of soil temperature can be precisely controlled to meet the temperature uniformity requirements of different experiments.

[0020] The heating device of this invention adopts a non-invasive installation method, that is, the heating tube is fixed in the soil container by a support assembly, without the need to bury the heating element directly into the deep soil layer, thus avoiding damage to the soil structure. This helps to maintain the original state of the soil and improves the accuracy of the experiment.

[0021] A positioning sleeve is fitted in the middle of the heating tube and locked in place by positioning bolts. This design makes the position and angle of the heating tube easy to adjust. Meanwhile, the lifting rod and height adjustment bolts in the support assembly allow the height of the heating tube to be adjusted as needed. Furthermore, the cable management conduit design ensures that the heating tube wiring is organized and positioned in an orderly manner, facilitating the maintenance and repair of the device.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a soil warming device that uses a heating pipe installed at a 45-degree angle, such as... Figures 1-5As shown, the apparatus includes a soil container 1, inside which are installed several heating tubes 2 at a 45-degree angle. The bottom of the heating tubes 2 is supported and fixed by a support component 3, and the top of the heating tubes 2 is connected to a temperature controller 5 via wiring. The wiring at the top of the heating tubes 2 is organized and positioned using a wiring tube 4. By cleverly placing the heating tubes 2 at a 45-degree angle inside the soil container 1 and using the support component 3 for stable support, a stable and effective arrangement of the heating tubes 2 in the soil is achieved. The connection of the top of the heating tubes 2 to the temperature controller 5 via wiring allows for precise control of the soil temperature, meeting the specific soil temperature requirements of different experiments. At the same time, the wiring at the top of the heating tubes 2, organized and positioned using the wiring tube 4, not only makes the internal wiring neat and orderly, improving the overall aesthetics of the apparatus, but also facilitates the maintenance and repair of the wiring. This design ensures both the efficiency and uniformity of soil heating, and improves the practicality and operability of the apparatus.

[0031] In this embodiment, the heating tubes 2 are arranged in a ring with equal spacing inside the soil container 1. This arrangement ensures the uniformity of temperature distribution within the soil container. The equal spacing between the heating tubes 2 avoids localized overheating or insufficient temperature, providing a stable and uniform heating environment for the soil, which is beneficial to the accuracy and repeatability of scientific experiments.

[0032] Specifically, a positioning sleeve 21 is fitted around the middle of the heating tube 2, and a positioning bolt 22 is installed on the outside of the positioning sleeve 21. The heating tube 2 slides with the positioning sleeve 21 and is locked in place by the positioning bolt 22. This design allows the position of the heating tube 2 to be flexibly adjusted and securely locked by the positioning bolt 22. The combination of sliding fit and locking mechanism ensures the stability of the heating tube in the soil container 1 and facilitates position adjustment during installation and maintenance.

[0033] Furthermore, the bottom end of the heating tube 2 is provided with a pointed tip 23. The design of the pointed tip 23 helps the heating tube to be inserted into the soil more easily, reducing resistance during installation. At the same time, the shape of the pointed tip also helps to stabilize the heating tube in the soil and prevent it from shifting during use.

[0034] Furthermore, the support assembly 3 includes a fixing sleeve 31, with a lifting rod 32 inserted into the top of the fixing sleeve 31. The top end of the lifting rod 32 is connected and fixed to the positioning sleeve 21, and the bottom end of the fixing sleeve 31 is connected and fixed to the bottom inner wall of the soil container 1. The support assembly 3 provides a stable support structure for the heating tube 2. Through the insertion connection between the lifting rod 32 and the fixing sleeve 31, the height of the heating tube 2 can be easily adjusted to adapt to different soil depths and experimental requirements. The connection between the fixing sleeve 31 and the bottom of the soil container 1 ensures the stability of the entire support structure.

[0035] Furthermore, a height adjusting bolt 33 is installed on the upper side of the fixed sleeve 31. The lifting rod 32 slides in conjunction with the fixed sleeve 31 and is locked in place by the height adjusting bolt 33. The design of the height adjusting bolt 33 allows the height of the lifting rod 32 to be precisely adjusted and maintained stable by the locking mechanism. This height adjustability enhances the flexibility and adaptability of the device, meeting the height adjustment requirements under different experimental conditions.

[0036] Furthermore, the cable management tube 4 has a ring-shaped structure with several side openings 41 on its outer wall. Several radial tubes 42 are connected to the inner side of the cable management tube 4, and a central opening 43 is provided at the end of each radial tube 42. The design of the cable management tube 4 effectively organizes the top wiring of the heating tube 2, making the wiring clear and orderly. The ring-shaped structure and the side openings 41 facilitate the insertion and exit of the wiring, while the radial tubes 42 and the central opening 43 provide points for wiring convergence and fixation, improving the overall aesthetics of the device and the safety of the wiring.

[0037] Furthermore, the side openings 41 are arranged in a ring with equal spacing. This equal spacing ensures a uniform distribution of cables on the cable management tube 4, preventing cable accumulation and crossing. This design makes cable management simpler and more efficient, improving the reliability and ease of use of the device.

[0038] In use, the soil heating device of this invention, which employs a 45-degree angle installation of heating tubes, firstly places several heating tubes 2 at a 45-degree angle inside the soil container 1. The bottom of the heating tubes 2 is supported and fixed by a support assembly 3, which includes a fixing sleeve 31, a lifting rod 32, and a height adjusting bolt 33. The fixing sleeve 31 is connected and fixed to the bottom inner wall of the soil container 1, and the lifting rod 32 is inserted into the top of the fixing sleeve 31 and locked in place by the height adjusting bolt 33, thereby achieving precise adjustment of the height of the heating tubes 2.

[0039] A positioning sleeve 21 is fitted in the middle of the heating tube 2, and a positioning bolt 22 is installed on the outside of the positioning sleeve 21. The heating tube 2 and the positioning sleeve 21 are slidably engaged, and the positioning is locked in place by the positioning bolt 22 to ensure the stability of the heating tube 2 in the soil container 1, while also facilitating position adjustment during installation and maintenance.

[0040] The bottom end of the heating tube 2 is provided with a pointed tip 23, which helps the heating tube to be inserted into the soil more easily and to be stably fixed in the soil, preventing it from shifting during use.

[0041] The top of the heating tube 2 is connected to the temperature controller 5 via wiring, allowing for precise control of the soil temperature. The temperature controller 5 controls the heating power of the heating tube 2 according to preset temperature parameters, thus achieving precise soil temperature control. The wiring at the top of the heating tube 2 is organized and positioned using a wiring guide tube 4. The wiring guide tube 4 has a ring structure with several equally spaced side openings 41 on its outer wall for easy insertion and exit of the wiring. Several radial tubes 42 are connected to the inner side of the wiring guide tube 4, and each radial tube 42 has a central opening 43 at its end, providing a point for wiring convergence and fixation.

[0042] When soil temperature needs to be increased, the temperature controller 5 receives preset temperature parameters and controls the heating tube 2 to start heating. The heating tube 2 converts electrical energy into heat energy and, through a 45-degree angled setting, evenly transfers the heat to the soil, with the heat diffusing upwards from the entire bottom of the soil container 1. Because the heating tubes 2 are arranged in a ring with equal spacing inside the soil container 1, the temperature distribution inside the soil container 1 is uniform, avoiding local overheating or insufficient temperature. The support assembly 3 ensures the stable arrangement of the heating tubes 2 in the soil; even if the soil moisture or temperature changes, the heating tubes 2 can maintain a fixed position without affecting the heating effect.

[0043] Finally, it should be noted that the electronic components in the temperature controller 5 and other components in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between each electrical component in the above working principle to complete the electrical connection. All of these are technologies known in the art.
