Description

Self-charging, low-power remote transmission equipment for thermal pipelines based on the Seebeck effect Technical Field

[0001] This utility model relates to the field of self-charging technology for thermal pipelines, specifically to a self-charging low-power remote transmission device for thermal pipelines based on the Seebeck effect. Background Technology

[0002] The Seebeck effect, also known as the first thermoelectric effect, refers to the thermoelectric phenomenon caused by the temperature difference between two different electrical conductors or semiconductors, resulting in a voltage difference between the two substances. Under a temperature gradient, charge carriers in the conductor move from the hot end to the cold end and accumulate at the cold end, thus forming a potential difference inside the material. At the same time, a reverse charge flow is generated under the action of this potential difference. When the thermally moving charge flow and the internal electric field reach dynamic equilibrium, a stable thermoelectric potential is formed at both ends of the conductor. By utilizing this effect, thermal pipelines directly convert the temperature difference between the inside and outside of the pipeline into electrical energy, achieving self-powered operation. This solves the power supply problem for remote transmission equipment on thermal pipelines, eliminating the need for separate circuit connections or battery power.

[0003] When using the Seebeck effect to charge remote transmission equipment in thermal pipelines, the hot end of the thermocouple module is usually placed against the outer wall of the pipeline, while the cold end is naturally cooled using some heat dissipation structure, creating a certain temperature difference between the two ends to generate electricity. Thermal pipelines are usually buried underground or in trenches. However, to ensure the transmission of communication signals and facilitate maintenance, this equipment is usually installed in some pipeline valve chambers. The heat dissipation method used is usually to remove heat through natural wind. However, the direction of natural wind is uncertain and does not always blow directly on the thermocouple module, resulting in poor heat dissipation effect of the cold end of the thermocouple module, especially when the air circulation is slow. The temperature difference between the hot and cold ends of the thermocouple module is small, resulting in low power generation efficiency. Therefore, we propose a self-charging low-power remote transmission device based on the Seebeck effect for use in thermal pipelines. Summary of the Invention

[0004] The purpose of this invention is to provide a self-charging, low-power remote transmission device based on the Seebeck effect for use in thermal pipelines, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-charging, low-power remote transmission device based on the Seebeck effect applied to a thermal pipeline, comprising a thermal pipeline, a fixed pipe and a charging base fixedly installed on the thermal pipeline, a communication device for remote transmission fixedly installed on the charging base, and a battery for powering the communication device, a DC-DC converter for ensuring stable power output fixedly installed on the battery, several thermocouple modules for power generation fixedly installed on the fixed pipe, a heat sink fixedly installed on the outside of the thermocouple modules, current collectors fixedly installed at both ends of the fixed pipe, each current collector being arranged in a funnel shape along the laying direction of the thermal pipeline, with the narrow end of the funnel facing the fixed pipe, and several air inlets arranged in a ring on each current collector.

[0006] Preferably, a plurality of heat sinks for heat dissipation are fixedly installed on the heat sink plate, and a guide plate for guiding airflow to the heat sink plate and heat sinks is fixedly installed on one side of each air inlet.

[0007] Preferably, a sliding rod is fixedly connected between each pair of corresponding air guide plates, and a cleaning brush for cleaning dust on the heat sink and heat fins is slidably installed on each sliding rod. The cleaning brush is pushed by the wind force to slide.

[0008] Preferably, a plurality of rotating shafts are rotatably mounted between the two air intake shrouds, and a plurality of blades for accelerating airflow are fixedly mounted on each rotating shaft, the blades being arranged in a ring.

[0009] Preferably, the fixing tube, heat sink, and heat fins are all made of aluminum alloy material with good thermal conductivity.

[0010] Preferably, a thermally conductive silicone grease coating is provided between the fixed pipe and the heat pipe to facilitate heat transfer.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a funnel-shaped shroud to collect airflow over a larger area, while the airflow can only be discharged through the inlet. Due to the limited area of ​​the inlet, the discharged airflow can be pressurized. The guide plate directs the pressurized airflow to the heat sink and fins, which accelerates the airflow on the surface of the heat sink and fins, allowing more heat to be carried away and improving heat dissipation efficiency. The thermocouple module also forms a large temperature difference between its hot and cold ends, improving power generation efficiency.

[0013] 2. This utility model utilizes the airflow to disperse after colliding with the back of the collector shroud to push the blades. During the rotation of the blades, the airflow between two adjacent collector shrouds can be accelerated, allowing the air that has absorbed heat from the heat sink and fins to be quickly discharged, thus improving heat dissipation efficiency. Furthermore, when the wind pushes the airflow directly between the two collector shrouds, the back of the two collector shrouds can concentrate the airflow. At the same time, the airflow pushes the blades to rotate, changing the direction of airflow and making it easier for the airflow to blow onto the surface of the heat sink and fins.

[0014] 3. This utility model utilizes wind power to propel the cleaning brush to slide on the slide bar, cleaning dust and impurities on the surface of the heat sink and heat fins, thereby improving the heat dissipation efficiency of the heat sink and heat fins. Moreover, the wind does not blow from one direction; when the wind direction changes, the cleaning brush can slide in the opposite direction to clean. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please refer to Figures 1-5. This utility model provides a technical solution: a self-charging, low-power remote transmission device based on the Seebeck effect applied to a heat pipe, including a heat pipe 1, a fixed pipe 3 and a charging base 7 fixedly installed on the heat pipe 1, a communication device 10 for remote transmission fixedly installed on the charging base 7, and a battery 8 for powering the communication device 10. A DC-DC converter 9 for ensuring stable power output is fixedly installed on the battery 8 (the DC-DC converter described in this utility model is a step-up / step-down type DC-DC converter). The converter (capable of boosting or bucking DC power) has a thermally conductive silicone grease coating 2 between the fixed pipe 3 and the heat pipe 1 to facilitate heat transfer. This coating isolates the air between the fixed pipe 3 and the heat pipe 1, allowing heat from the heat pipe 1 to be transferred to the fixed pipe 3 to the maximum extent. Several thermocouple modules 4 for power generation are fixedly installed on the fixed pipe 3. Each thermocouple module 4 has a heat sink 5 fixedly installed externally. The hot end of the thermocouple module 4 is connected to the fixed pipe 3, allowing heat from the heat pipe 1 to be transferred to the hot end of the thermocouple module 4. The cold end of the thermocouple module 4 is connected to the heat sink 5, so that the hot end and cold end of the thermocouple module 4 form a temperature difference and generate electricity using the temperature difference. The current is transmitted to the charging base 7 through the line and converted into a stable current by the DC-DC converter 9 to enter the storage battery 8. At the same time, the storage battery 8 releases electricity and converts it into a stable current again by the DC-DC converter 9 to power the communication device 10. The DC-DC converter 9 is equipped with two separate power conversion modules, which can regulate the voltage of the input current and the output current respectively, and reduce power consumption, so that the communication device 10 can stably carry out remote transmission.

[0023] Several heat sinks 6 are fixedly installed on the heat sink 5 for heat dissipation. The fixed pipe 3, heat sink 5, and heat sinks 6 are all made of aluminum alloy with good thermal conductivity, which makes the heat transfer of the heat pipe 1 better and improves the heat dissipation efficiency of the heat sink 5 and heat sinks 6. Both ends of the fixed pipe 3 are fixedly installed with flow collectors 11. Each flow collector 11 is arranged in a funnel shape along the laying direction of the heat pipe 1, and the narrow end of the funnel faces the fixed pipe 3. Several air inlets 12 are arranged in a ring on each flow collector 11. Each air inlet 12 is fixedly installed on one side with a guide plate 13 for guiding the air to the heat sink 5 and heat sinks 6. When the wind pushes the air along the flow collector 12, the flow collector 13 is fixedly installed on the side of the heat sink 5 and heat sink 6. When the airflow flows through the heat pipe 1, the funnel-shaped shroud 11 can collect a larger area of ​​airflow. The airflow in the shroud 11 can only be discharged through the air inlet 12. Because the air inlet 12 has a limited area, it can pressurize the discharged airflow. The guide plate 13 directs the pressurized airflow towards the heat sink 5 and heat fins 6, accelerating the airflow over their surfaces and allowing more heat to be carried away, thus improving heat dissipation efficiency. A large temperature difference is formed between the hot and cold ends of the thermocouple module 4, improving power generation efficiency. A sliding rod 16 is fixedly connected between every two corresponding guide plates 13, and each sliding rod 16 has a sliding... A cleaning brush 17 is installed to clean dust from the heat sink 5 and heat sink 6. The cleaning brush 17 slides under the force of the wind. When pressurized airflow rushes towards the heat sink 5 and heat sink 6, the cleaning brush 17 is pushed by the wind to slide on the slide bar 16, cleaning the dust and impurities on the surface of the heat sink 5 and heat sink 6, thus improving the heat dissipation efficiency of the heat sink 5 and heat sink 6. Moreover, the wind does not blow from one direction. When the wind direction changes, the cleaning brush 17 can slide in the opposite direction to clean. Several rotating shafts 14 are rotatably installed between the two air collectors 11. Several blades 15 for accelerating airflow are fixedly installed on each rotating shaft 14. The blades 15 are arranged in a ring. When the airflow enters between the two shrouds 11, it will collide with the back of the shroud 11 on the other side of the direction of entry. Then the airflow will spread out and push the blades 15. The blades 15 will drive the shaft 14 to rotate. During the rotation of the blades 15, the airflow between the two adjacent shrouds 11 can be accelerated, so that the air that has absorbed the heat of the heat sink 5 and the heat sink 6 can be quickly discharged, which further improves the heat dissipation efficiency. When the wind pushes the airflow directly between the two shrouds 11, the back of the two shrouds 11 can concentrate the airflow. At the same time, the airflow pushes the blades 15 to rotate, changing the direction of the airflow and making it easier for the airflow to blow onto the surface of the heat sink 5 and the heat sink 6.

[0024] Specifically, the heat from the heat pipe 1 is transferred to the fixed pipe 3 to the maximum extent via the thermally conductive silicone grease coating 2, and then transferred from the fixed pipe 3 to the hot end of the thermocouple module 4. The hot and cold ends of the thermocouple module 4 create a temperature difference to generate electricity. The current is transmitted through the circuit to the charging base 7, and then converted into a stable current by the DC-DC converter 9 to be stored in the battery 8. Simultaneously, the battery 8 releases electricity, which is again converted into a stable current by the DC-DC converter 9 to power the communication device 10 for transmission. When wind pushes air along the heat pipe 1, the funnel-shaped air collector 11 can collect a larger area of ​​airflow. The airflow in the air collector 11 is then discharged through the air inlet 12. The guide plate 13 directs the pressurized airflow to the heat sink 5 and the heat fins 6, accelerating the airflow on the surface of the heat sink 5 and the heat fins 6. More heat is carried away from the heat sink 5 and heat fin 6. At the same time, the cleaning brush 17 is pushed by the wind to slide on the slide bar 16 to clean the dust and impurities on the surface of the heat sink 5 and heat fin 6. After the airflow enters between the two collector shrouds 11, it will collide with the back of the collector shroud 11 on the other side of the flow direction. Then the airflow disperses and pushes the blade 15. The blade 15 will drive the rotating shaft 14 to rotate. During the rotation of the blade 15, it can accelerate the airflow between the two adjacent collector shrouds 11, so that the air that has absorbed the heat of the heat sink 5 and heat fin 6 can be quickly discharged. When the wind pushes the airflow directly between the two collector shrouds 11, the back of the two collector shrouds 11 can concentrate the airflow. At the same time, the airflow pushes the blade 15 to rotate, changing the direction of the airflow and making it easier for the airflow to blow onto the surface of the heat sink 5 and heat fin 6.
