Traditional liquid level gauges, such as float or magnetic flap level gauges, have difficulty working normally under such high temperature conditions and may even be quickly damaged or fail due to the material's inability to withstand high temperatures. Therefore, radar level gauges have been widely used in the copper smelting industry due to their non-contact measurement characteristics. Radar level gauges transmit high-frequency electromagnetic waves (radar waves) and receive the signals reflected from the liquid surface, using the time difference to calculate the liquid level. They have the advantages of accurate measurement and are not affected by the physical properties of the medium.

The limiting guide column 44 is vertically slidably connected to the inner wall of the heat insulating seat 322, one end of the limiting guide column 44 passes through the interior of the heat dissipation tube 321 and is fixedly connected to the top of the guide tube 42, and the other end of the limiting guide column 44 passes through the top of the heat insulating seat 322. , and is fixedly connected to the bottom of the thermal insulation cover 33. The guide cylinder 42 and the limiting guide post 44 are both hollow structures. The interior of the heat dissipation cylinder 321, the interior of the guide cylinder 42, the interior of the limiting guide post 44 and the interior of the thermal insulation cover 33 are connected; the interior of the thermal insulation cover 33 is adapted to the external dimensions of the radar level gauge body 1, and the thermal insulation cover 33 has a built-in vacuum chamber 331. The inner cover wall of the thermal insulation cover 33 is made of copper, and the outer cover wall of the thermal insulation cover 33 is made of silver-plated aluminum alloy.

[0038] It should be noted that the first thermal insulation pad 311 described in this embodiment is an aluminum silicate cotton felt roll, and the thermal insulation seat 322 is made of ceramic fiber material. The high temperature resistance of ceramic fiber can reach above 1000°C. A multi-layer reflective film (not shown in the figure) is also provided on the outer surface of the silver-plated aluminum alloy. The multi-layer reflective film is composed of multiple layers of metal films and polymer films alternately stacked, which reduces heat conduction by reflecting and scattering thermal radiation.

[0039] It should also be noted that, in order to facilitate the entry of radar waves into the furnace body, the heat dissipation tube 321 , the partition seat 314 , the fixing flange 312 , the first thermal insulation pad 311 and the horn antenna 2 are internally connected.

[0040] It should also be noted that the spring memory alloy 43 described in this embodiment is a prior art. The spring memory alloy 43 is a two-way memory alloy. The high-temperature deformation temperature of the spring memory alloy 43 is 100° and the low-temperature deformation temperature is 60°.

[0041] Specifically, the structures and connection relationships of the heat insulation component 31, cooling component 32, lifting component 4 and thermal insulation cover 33 are further explained. When in use, the first thermal insulation pad 311, the partition seat 314, the thermal insulation card seat 322 and the vacuum chamber 331 of the thermal insulation cover 33 can effectively play a heat insulation effect. The heat dissipation tube 321 effectively dissipates heat with its excellent heat dissipation performance, significantly reducing the heat load on the thermal insulation cover 33 and the radar level gauge body 1.

When in use, the heat dissipation tube 321 21. The heat of the inner wall of the lower end is conducted to the guide tube 42 and the spring memory alloy 43 through the heat conducting block 41. When the temperature is higher than the high-temperature deformation temperature of the spring memory alloy 43 (i.e., 100°), the spring memory alloy 43 is deformed by the heat, and its height dimension changes, and the guide tube 42 is simultaneously driven to move upward along the inner wall of the heat conducting block 41. The movement of the guide tube 42 simultaneously drives the limiting guide post 44 to move vertically upward along the inner wall of the heat insulating seat 322. The movement of the limiting guide post 44 simultaneously drives the thermal insulation cover 33 and the radar level gauge body 1 to move upward synchronously, thereby staying away from the heat source, further reducing the impact of high temperature on the radar level gauge body 1, and having a good use effect. Among them, the vacuum chamber 331 also plays a certain heat insulation effect, and has a good use effect.

[0042] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the lifting assembly 4 further includes a displacement detection assembly 5, which is used to monitor the displacement data of the radar level gauge body 1 during the lifting process in real time to ensure that the measuring height can be adjusted quickly and accurately.

[0043] Specifically, the displacement detection component 5 is provided to ensure that the measurement data can be adjusted synchronously during the lifting and lowering process of the radar level gauge body 1, thereby ensuring the accuracy of the measurement and the use effect.

[0044] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the displacement detection assembly 5 includes a stand 51, an outer cylinder 52, a displacement sensor 53 and an inner rod 54, wherein the stand 51 is vertically fixedly connected to the top of the fixed flange 312, the inner rod 54 is fixedly connected to the top of the radar level gauge body 1, the outer cylinder 52 is fixedly connected to the surface of the stand 51 and is slidably connected to the outer surface of the inner rod 54, the displacement sensor 53 is fixedly connected to the surface of the outer cylinder 52, and the displacement sensor 53 determines the position of the inner rod 54 by measuring the relative displacement between the inner rod 54 and the outer cylinder 52. The displacement sensor 53 sends the detected data information to the external control system, and the external control system receives the displacement data measured in real time by the displacement sensor 53 and the height data provided by the radar level gauge body 1, obtains the new height difference through precise calculation, and dynamically adjusts the measurement data accordingly.

[0045] It should be noted that the displacement sensor 53 described in this embodiment is a prior art and will not be described in detail here.

[0046] Specifically, the structure and connection relationship of the displacement detection component 5 are further explained. When in use, the radar level gauge body 1 rises and synchronously drives the inner rod 54 to move upward along the inner wall of the outer tube 52. The displacement sensor 53 determines the position of the inner rod 54 by measuring the relative displacement between the inner rod 54 and the outer tube 52, and sends the detected data information to the external control system. The external control system receives the displacement data measured in real time by the displacement sensor 53 and the height data provided by the radar level gauge body 1, obtains the new height difference through precise calculation, and dynamically adjusts the measurement data accordingly to ensure accurate measurement.

[0047] In one embodiment of the present invention, Figure 3 As shown, the displacement detection assembly 5 also includes a ring signal enhancer 100, which is fixedly connected to the inner wall of the heat dissipation tube 321 and is located on one side of the bottom of the heat conduction block 41. The ring signal enhancer 100, the radar level meter body 1 and the horn antenna 2 are on the same axis.

[0048] It should be noted that the ring signal enhancer 100 described in this embodiment is prior art and will not be described in detail here.

[0049] It should also be noted that in order to more effectively reduce the thermal impact of the inner wall temperature of the heat dissipation tube 321 on the annular signal enhancer 100, an insulation ring (not shown in the figure) is provided at the connection between the inner wall of the heat dissipation tube 321 and the surface of the annular signal enhancer 100. The insulation ring is made of ceramic fiber.

[0050] Specifically, the provision of the ring signal enhancer 100 has the following advantages: the ring signal enhancer 100 can enhance the penetration of the radar wave signal, making it easier to penetrate obstacles or attenuation areas in the measured medium, ensuring that the signal can reach and accurately reflect back to the radar level meter body 1; during the signal transmission process, the radar wave signal will attenuate due to medium absorption, scattering, etc. The ring signal enhancer 100 can compensate for this attenuation, ensuring that the signal strength is still strong enough when it reaches the measured object, thereby improving the accuracy and reliability of the measurement; in the measurement environment, there may be noise interference from other equipment or natural phenomena, which may affect the measurement accuracy of the radar level meter body 1, and the ring signal enhancer 100 can effectively reduce the attenuation of the radar wave signal. By enhancing useful signals and suppressing noise interference, the signal-to-noise ratio can be improved, thereby reducing the impact of noise on measurement accuracy. The ring signal enhancer 100 can pre-process and optimize the received signal, such as filtering and amplification, to improve signal quality, enabling the radar level meter body 1 to more accurately analyze and process the reflected signal, thereby improving measurement accuracy. In certain high-temperature, high-pressure, or highly corrosive measurement environments, direct contact between the radar level meter body 1 and the object being measured may cause damage or performance degradation. By providing the ring signal enhancer 100 between the object being measured and the radar level meter body 1, the impact of these harsh environments on the radar level meter body 1 can be isolated, thereby protecting the device and extending its service life.

What is particularly clever is that the device has a built-in lifting component 4. When it detects that the temperature at the lower end of the heat dissipation tube 321 is approaching the preset high temperature threshold, the component can quickly start and automatically lift the thermal insulation cover 33 together with the radar level gauge body 1 to a safe position. Through a precise physical isolation strategy, the adverse effects of the high temperature environment are further weakened, showing excellent adaptability and flexibility, and greatly improving the use effect and equipment reliability.
