Description

Technical Field

[0001] The utility model relates to the technical field of ground temperature sensors, in particular to a ground temperature sensor hub. Background Art

[0002] Ground temperature is an important observation element in the meteorological field. The change of ground temperature can reflect the trend of global warming, and at the same time, it can also provide a scientific basis for weather forecasting and coping with climate events such as global warming. The utility model can be compatible with a variety of different types of ground temperature sensors, making it adaptable to different application scenarios and user needs, whether it is a high-precision thermistor ground temperature sensor or a ground temperature sensor based on the thermocouple principle.

[0003] In modern agriculture, ground temperature plays a crucial role in the growth and development of crops. Farmers can accurately grasp the soil temperature conditions, so as to reasonably arrange the sowing time, irrigation plan and fertilization strategy. At the same time, for some temperature-sensitive crops, such as strawberries and flowers, the soil temperature needs to be strictly controlled during the planting process to improve the yield and quality of crops.

[0004] Currently, the ground temperature observation items in the meteorological observation field include surface temperature and shallow ground temperature. Each ground temperature observation level requires a sensor. These ground temperature sensors are all connected to the ground temperature collector through a long signal cable through pipes and trenches. When the ground temperature sensor needs to be repaired, replaced or calibrated, the ground temperature sensor and the entire signal cable need to be pulled out from the pipes and trenches. Due to the large number of ground temperature sensors, the cables in the trenches and pipes are entangled and knotted with each other, which brings great difficulties to the repair, replacement and calibration of the ground temperature sensors. In addition, since the ground temperature sensor needs to be pulled out from the pipes and trenches, it will also cause deformation and damage of the ground temperature sensor and damage to the signal cable, resulting in unnecessary equipment losses. Summary of the Utility Model

[0005] In the prior art, the cables in the trenches and pipes are entangled and knotted with each other, which brings great difficulties to the repair, replacement and calibration of the ground temperature sensors. In addition, since the ground temperature sensor needs to be pulled out from the pipes and trenches, it will also cause deformation and damage of the ground temperature sensor and damage to the signal cable. To improve and make up for the above problems and deficiencies, the utility model provides a ground temperature sensor hub.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A geothermal sensor hub, comprising a thin-walled circular tube, wherein a hole is provided inside the bottom of the thin-walled circular tube, a connecting block is clamped at the top inside the hole, guide rails are fixedly connected to the left and right sides of the bottom of the connecting block, a terminal block is fixedly connected to the top between the two adjacent guide rails, partition plates are slidably connected to the outer walls of the guide rails, a grooved end cover is clamped at the middle of the top of the thin-walled circular tube, and ventilation holes are provided at the top of the outer wall of the thin-walled circular tube.

[0007] As a further description of the above technical solution:

[0008] A second protective ring is fixedly connected to the middle upper part of the outer wall of the thin-walled circular tube.

[0010] A protective block is fixedly connected to the middle of the outer wall of the thin-walled circular tube.

[0011] As a further description of the above technical solution:

[0012] A first protective ring is fixedly connected to the middle lower part of the outer wall of the thin-walled circular tube.

[0013] As a further description of the above technical solution:

[0014] A sharp cone is fixedly connected to the bottom of the guide rail.

[0015] As a further description of the above technical solution:

[0016] C-shaped cable card slots are provided around the outer wall of the partition plate.

[0017] As a further description of the above technical solution:

[0018] The two guide rails are both arranged at the same horizontal height.

[0019] The utility model has the following beneficial effects:

[0020] 1. In the utility model, the geothermal sensor signal cable is first connected to the terminal block, and then connected to the geothermal collector through pipelines and trenches. During maintenance, replacement and calibration, only the sensor part needs to be pulled out, and the signal cables in the pipelines and trenches do not need to be pulled out. At the same time, the thin-walled circular tube can protect the geothermal sensor signal cable, avoiding sun exposure and rat bites, and having a good protection effect.

[0021] 2. In the present utility model, through the air vents at the connection end of the thin-walled circular tube and the grooved end cover, the water vapor evaporated from the soil into the thin-walled circular tube can be dissipated, preventing the water vapor from accumulating and corroding the circuit board on the terminal block. At the same time, the groove edge of the grooved end cover is lower than the air vents on the thin-walled circular tube, which can prevent rainwater from entering the interior of the thin-walled circular tube. The wiring sequence on the terminal block corresponds to the ground temperature observation levels, avoiding confusion during replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to the attached Figure 1 -attached Figure 3, an embodiment provided by the present utility model: a ground temperature sensor hub, including a thin-walled circular tube 1. A hole 12 is opened in the inner bottom of the thin-walled circular tube 1, and a connecting block 10 is clamped at the inner top of the hole 12. This connecting block 10 is not only a structural support point but also a key anchor point in the subsequent installation process. On the left and right sides of the bottom of the connecting block 10, guide rails 3 are fixedly connected. On the top between the two adjacent guide rails 3, a terminal block 9 is fixedly connected. The outer walls of the guide rails 3 are all slidably connected with partition plates 8. Two guide rails 3 are symmetrically fixed. These two guide rails 3 not only provide a stable sliding track for the internal components. These ventilation holes 11 are like miniature vents. This end cover not only plays a role in closing and protecting the internal components. Ventilation holes 11 are opened at the top of the outer wall of the thin-walled circular tube 1, and a protective block 6 is fixedly connected to the middle of the outer wall of the thin-walled circular tube 1;

[0031] Specifically, through this hole 12, it is not just a simple opening but a structure with specific functions, preventing them from interfering with each other and playing a role in heat dissipation to a certain extent. The sliding connection mode of the partition plate 8 enables them to be adjusted according to needs to adapt to electronic components of different sizes and shapes. This grooved end cover 2 not only plays a role in closing and protecting. The design of these ventilation holes 11 enables heat to be effectively discharged from the inside of the thin-walled circular tube 1, thereby reducing the internal temperature and ensuring the stable operation of the entire system.

[0032] Please refer to the appendix Figure 4 -appendix Figure 5 , a protective ring two 7 is fixedly connected to the middle and upper part of the outer wall of the thin-walled circular tube 1. A pointed cone 4 is specially designed at the bottom of the guide rail 3. The pointed cone 4 penetrates into the ground, providing stable support for the guide rail 3 and ensuring its stability under various working conditions. The bottom of the guide rail 3 is fixedly connected with a pointed cone 4. A protective ring one 5 is fixedly connected to the middle and lower part of the outer wall of the thin-walled circular tube 1. C-shaped cable slots 13 are opened around the outer wall of the partition plate 8. The design of the partition plate 8 reflects careful consideration for cable management. The evenly opened C-shaped cable slots 13 around its outer wall provide a convenient way for cable fixing and arrangement. The two guide rails 3 are both set at the same horizontal height;

[0033] Specifically, through this design, it aims to provide additional protection to prevent damage to the thin-walled circular tube 1 due to external forces during use. The setting of the protective ring two 7 not only enhances the structural stability of the thin-walled circular tube 1. The tip of the pointed cone 4 can penetrate into the ground, providing good grip, thus ensuring that the guide rail 3 will not easily move or tip over when bearing heavy objects or being affected by external forces. The opening design of the C-shaped cable slot 13 makes it very convenient to insert and remove cables, and at the same time can effectively fix the cables to prevent them from slipping or falling off. The setting at the same horizontal height is also convenient for equipment installation and maintenance, improving the overall use efficiency.

[0034] Working principle: It is composed of a thin-walled circular tube 1 and a grooved end cover 2. Subsequently, the outer diameter of the thin-walled circular tube 1 is slightly smaller than the inner diameter of the grooved end cover 2. At the same time, a circle of ventilation holes 11 are evenly drilled at the connection end of the thin-walled circular tube 1 and the grooved end cover 2. The groove edge of the grooved end cover 2 is lower than the ventilation holes 11. At this time, it is composed of two parallel guide rails 3 and partitions 8 and terminal blocks 9 installed on the guide rails 3. Subsequently, one end of the guide rail 3 is fixed to the sharp cone 4, and the other end is a plane. The two guide rails 3 are fixed by the connecting piece at the plane end. Then, the lower partition 8 is at a certain distance from the sharp cone 4 of the guide rail 3. Each partition 8 is provided with a C-shaped cable slot 13 along the edge. The partition 8 is fixed to the guide rail 3 by screws. Therefore, it is realized that the signal cable of the ground temperature sensor is first connected to the terminal block 9, and then connected to the ground temperature collector through the pipeline and the trench. During maintenance, replacement, and calibration, only the sensor part needs to be pulled out, and the signal cable in the pipeline and the trench does not need to be pulled out. At the same time, the thin-walled circular tube 1 can protect the signal cable of the ground temperature sensor, avoiding sun exposure and rodent bites, and has a good protection effect.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
