Description

Technical Field

[0001] This utility model relates to the field of testing instruments and equipment, specifically a channel temperature detection device. Background Technology

[0002] In numerous fields such as industrial production, building maintenance, and underground pipeline inspection, the monitoring of internal environmental parameters is crucial, with temperature monitoring being a common and critical aspect. Accurately obtaining temperature information within the pipeline helps in the timely detection of potential safety hazards, such as leaks and fires caused by overheating, thereby ensuring the safety of equipment and personnel and improving the operational stability of the system.

[0003] Currently, for channel temperature detection, the common methods are external channel temperature detection (such as using infrared technology) or using a flexible tube to carry a temperature sensor and insert it into the pipe. The former has a high detection cost, and when the channel is deep underground, it is difficult to obtain the temperature information inside the channel from the ground. The latter has a limited insertion distance into the channel, making it difficult to obtain accurate temperature information inside the channel. It can be seen that there are many inconveniences in current channel temperature detection. There is a lack of equipment on the market specifically for channel temperature detection. In view of this, this application proposes a channel temperature detection device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a channel temperature detection device to solve the technical problem of inconvenience in current channel temperature detection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a channel temperature detection device, comprising a platform, a temperature sensor mounted on the top of the platform, a pair of drive wheels rotatably mounted on the bottom of one end of the platform, and a pair of travel wheel sets mounted on the bottom of the other end of the platform. The drive wheels and the travel wheel sets are distributed on both sides of the platform. A dual-head motor is embedded in the end of the platform facing the drive wheels, and the two output shafts of the dual-head motor are respectively connected to the rotation shafts of the pair of drive wheels. The travel wheel sets include a wheel frame and rollers. The wheel frame is rotatably mounted on the platform, and the rollers are rotatably mounted on the wheel frame, with three rollers evenly arranged around the wheel frame.

[0006] The present invention is further provided that a foam board is adhered and fixed to the lower surface of the vehicle panel.

[0007] The present invention is further configured such that blades are provided on the surface of the power wheel, and a plurality of blades are evenly arranged around the power wheel.

[0008] The present invention is further configured such that the wheel surface of the power wheel and the surface of the blades are both covered with a first rubber sleeve.

[0009] The present invention is further provided that a second rubber sleeve is tightly fitted on the roller.

[0010] The present invention is further configured such that a control housing is provided on the upper surface of the vehicle panel, and a circuit board is provided inside the control housing. The circuit board integrates a microcontroller, a wireless communication module, and a power module. A cable is connected to the power module, and the cable passes through the top wall of the control housing towards the drive wheel and extends out of the control housing. The microcontroller is connected to the power module, temperature sensor, and wireless communication module through the circuit board.

[0011] The present invention is further configured such that the cable consists of a steel wire, a power cord, and a signal transmission line.

[0012] In summary, the present invention has the following main advantages: This invention utilizes a three-roller wheel assembly arranged around a wheel frame, enabling it to effectively overcome small obstacles within the passageway during forward movement and improving its traversal capabilities in various passage environments. Simultaneously, a foam board at the bottom of the vehicle allows the device to float on the liquid surface in passages containing liquid, and the blades of the drive wheel further propel the device across the liquid surface, expanding its applicability and adaptability to diverse passage environments.

[0013] This invention utilizes both a wireless communication module and a signal transmission line for data transmission. The microcontroller can choose between wireless or wired transmission based on the specific circumstances, facilitating wireless transmission in environments where wiring is not feasible, while allowing for wired transmission in situations requiring stable data transmission, thus improving the flexibility and reliability of data transmission.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] A channel temperature detection device, such as Figure 1-6 As shown, it includes a vehicle platform 1, a temperature sensor 3, a drive wheel 4, and a set of traveling wheels 6. The temperature sensor 3 is installed on the top of the vehicle platform 1. The temperature sensor 3 is a thermocouple sensor used to detect the temperature in the channel.

[0019] In this embodiment, a pair of drive wheels 4 are rotatably mounted on the bottom of one end of the vehicle plate 1, and a pair of travel wheel sets 6 are mounted on the bottom of the other end of the vehicle plate 1. The drive wheels 4 and the travel wheel sets 6 are respectively distributed on both sides of the vehicle plate 1. A dual-head motor 5 is embedded in the end of the vehicle plate 1 facing the drive wheels 4. The two output shafts of the dual-head motor 5 are respectively connected to the rotation shafts of the pair of drive wheels 4 through couplings, providing power for the rotation of the drive wheels 4.

[0020] Furthermore, in this embodiment, the traveling wheel assembly 6 includes a wheel frame 14 and rollers 15. The wheel frame 14 is rotatably mounted on the vehicle platform 1, and the rollers 15 are rotatably mounted on the wheel frame 14, with three rollers 15 evenly arranged around the wheel frame 14. This structural design enables the traveling wheel assembly 6 to have a certain obstacle-crossing ability during forward movement, adapting to different road conditions within the passage and improving the adaptability of the device.

[0021] Furthermore, in this embodiment, a plurality of blades 12 are evenly arranged on the surface of the power wheel 4, and both the surface of the power wheel 4 and the surface of the blades 12 are covered with a first rubber sleeve 13. The first rubber sleeve 13 not only serves a protective function and reduces component wear, but also increases the friction with the ground and improves the power transmission efficiency. A second rubber sleeve 16 is tightly fitted on the roller 15, which also serves to protect and increase friction. A foam board 21 is adhered and fixed to the lower surface of the vehicle plate 1. When the device is in a channel containing liquid, the foam board 21 can provide sufficient buoyancy to make the device float on the liquid surface. At this time, the plurality of blades 12 on the surface of the power wheel 4 act as paddles. During the rotation of the power wheel 4, the interaction between the blades 12 and the liquid drives the vehicle plate 1 to move on the liquid surface in the channel.

[0022] In a further embodiment, a control housing 2 is mounted on the top of the vehicle body 1. Inside the control housing 2 is a circuit board 8, which integrates a power module 9, a microcontroller 10, and a wireless communication module 11. A temperature sensor 3 is mounted on the control housing 2. A cable 7 is connected to the power module 9, passing through the top wall of the control housing 2 towards the drive wheel 4 and extending out of the control housing 2. The microcontroller 10 is connected to the power module 9, the temperature sensor 3, and the wireless communication module 11 via the circuit board 8.

[0023] In this embodiment, cable 7 consists of steel wire 17, power cord 18, and signal transmission line 19. Power cord 18 is connected to power module 9 to provide power to the entire device; signal transmission line 19 is connected to microcontroller 10 via circuit board 8 for wired signal transmission; steel wire 17 is fixed to vehicle platform 1, acting as a traction device to facilitate the retraction of the device from the passage. Power cord 18 and signal transmission line 19 are spirally distributed around steel wire 17, and a polyurethane outer sheath 20 is wrapped around the outside of steel wire 17, power cord 18, and signal transmission line 19. The outer sheath 20 protects the internal structure of cable 7 from damage by the external environment.

[0024] The working principle of this utility model: When the temperature detection device needs to be deployed in the channel for temperature detection, one end of the steel wire 17 in the cable 7 is fixed outside the channel to ensure that the steel wire 17 can provide sufficient traction. The power cord 18 is connected to an external power source, and then the device is started. The power module 9 supplies power to the entire device through the power cord 18. The microcontroller 10 issues a command to start the dual-head motor 5. The two output shafts of the dual-head motor 5 drive a pair of drive wheels 4 to rotate. In a channel with liquid, several blades 12 on the surface of the drive wheels 4 act as paddles, driving the vehicle plate 1 to move on the liquid surface in the channel through interaction with the liquid. In a dry channel, the blades 12 on the drive wheels 4 directly contact the channel floor, driving the vehicle plate 1 forward through friction. During the movement of the vehicle plate 1, the three evenly distributed rollers 15 on the traveling wheel set 6 can better adapt to obstacles that may exist in the channel. When encountering small obstacles, the three rollers 15 can rotate flexibly to overcome the obstacles, ensuring the smooth movement of the device. During the movement, the temperature sensor 3 detects the temperature information in the channel in real time and transmits the detected temperature signal to the microcontroller 10. After processing the temperature signal, the microcontroller 10 transmits the temperature data wirelessly via the wireless communication module 11 or via the signal transmission line 19, according to a preset communication method, to an external receiving device so that staff can obtain the temperature information within the channel. After the testing is completed, the device can be pulled back from the channel by pulling the steel wire 17 in the cable 7.
