Description

Technical Field

[0001] The utility model relates to the technical field of combined instrument detection, in particular to a combined instrument temperature auxiliary calibration device. Background Technique

[0002] The existing combined instrument for ton barrels generally combines multiple functions such as temperature, liquid level, and pressure. The combined instrument with a liquid level function generally has a metal electrode under the probe rod. The electrode is fixed on the probe rod by welding. There is an insulating layer between the electrode and the probe rod. The insulating layer physically isolates the electrode from the probe rod, which results in tiny gaps between the insulating layer and the electrode and between the insulating layer and the probe rod.

[0003] Generally, the combined instrument must be calibrated before leaving the factory. When calibrating the temperature of the combined instrument, the probe rod needs to be inserted into a constant temperature water-oil bath. Since negative temperatures need to be calibrated, the medium in the constant temperature water-oil bath is generally automotive antifreeze. The probe rod will hang liquid, and the gaps between the insulating layer and the electrode will also be immersed in the liquid. After each temperature calibration, the probe rod needs to be thoroughly rinsed, which wastes a large amount of man-hours and water resources. Moreover, it is not guaranteed whether the gaps of the electrode are washed clean. In the case of large-scale production, the probability of not being washed clean will increase. During the use of this instrument probe rod, the electrolyte will be contaminated, resulting in the scrapping of the electrolyte. Therefore, in view of the above problems, a combined instrument temperature auxiliary calibration device is designed to better meet the actual use requirements. Content of the Utility Model

[0004] The purpose of the utility model is to provide a combined instrument temperature auxiliary calibration device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A combined instrument temperature auxiliary calibration device, including a cylindrical barrel, graphene thermal conductive foam, and a combined instrument body. The cylindrical barrel is connected to the graphene thermal conductive foam. The combined instrument body is arranged above the graphene thermal conductive foam. A probe is fixed at the lower end of the combined instrument body. A connecting rod is fixed on the left side of the cylindrical barrel.

[0006] Preferably, the cylindrical barrel is made of stainless steel, and the cylindrical barrel and the graphene thermal conductive foam are connected in a nested manner, and are fixedly bonded by thermal conductive glue between the cylindrical barrel and the graphene thermal conductive foam. By defining the material of the cylindrical barrel, the corrosion resistance of the cylindrical barrel can be guaranteed. And through the fixation of the thermal conductive glue between the cylindrical barrel and the graphene thermal conductive foam, the stability of the connection between the cylindrical barrel and the graphene thermal conductive foam can be guaranteed, and the thermal conductive effect between the cylindrical barrel and the graphene thermal conductive foam can also be guaranteed.

[0007] Preferably, round holes are also provided on the graphene heat-conducting foam, and the round holes are nested with the probes. By nesting the round holes with the probes, the stability of the combination formed by the combination meter body and the graphene heat-conducting foam can be ensured.

[0008] Preferably, the other end of the connecting rod is fixed with a U-shaped frame, and a guide rod is fixed inside the U-shaped frame. By the action of the connecting rod and the U-shaped frame, a basic guarantee for the fixation of the cylindrical tube can be provided.

[0009] Preferably, the U-shaped frame is connected to the threaded rod by a thread, and the threaded rod is connected to the clamping plate by a bearing. By the threaded connection between the threaded rod and the U-shaped frame, a basic guarantee for the position adjustment of the clamping plate can be provided, thereby providing a basic guarantee for the fixation of the device.

[0010] Preferably, a slider is further fixed on the upper end of the clamping plate, and the slider is slidably connected to the U-shaped frame. When the clamping plate moves, the sliding guiding action between the slider and the U-shaped frame can ensure the stability of the movement of the clamping plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The temperature auxiliary calibration device for the combination meter adopts a clamping and limiting mechanism, which can fix the whole device on the constant temperature water-oil bath. With the rapid heat conduction of the cylindrical tube and the graphene heat-conducting foam, the temperature calibration of the combination meter body can be realized. During the calibration process, the probe rod never contacts the medium in the constant temperature bath. The heat conduction function of the calibration device ensures the rapid transfer of the constant temperature of the constant temperature bath to the combination meter, ensuring the test efficiency. After calibration, the probe rod of the meter does not need to be cleaned, thus saving working hours and water resources, eliminating the interference factors before the combination meter contacts the electrolyte, improving the product yield, and better meeting the requirements of meter detection and calibration.

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a combined instrument temperature auxiliary calibration device, including a cylindrical barrel 1, a graphene thermal conductive foam 2 and a combined instrument body 3. The cylindrical barrel 1 is connected to the graphene thermal conductive foam 2. The combined instrument body 3 is arranged above the graphene thermal conductive foam 2. A probe 301 is fixed at the lower end of the combined instrument body 3. A connecting rod 4 is fixed on the left side of the cylindrical barrel 1.

[0018] The cylindrical barrel 1 is made of stainless steel, and the cylindrical barrel 1 and the graphene thermal conductive foam 2 are nestedly connected, and the cylindrical barrel 1 and the graphene thermal conductive foam 2 are fixedly bonded by a thermal conductive adhesive; a circular hole 201 is also opened on the graphene thermal conductive foam 2, and the circular hole 201 and the probe 301 are nestedly connected; the other end of the connecting rod 4 is fixed with a U-shaped frame 5, and a guide rod 501 is fixed inside the U-shaped frame 5; the U-shaped frame 5 is connected to a threaded rod 6 through a thread, and the threaded rod 6 is connected to a clamping plate 7 through a bearing; a slider 701 is also fixed at the upper end of the clamping plate 7, and the slider 701 and the U-shaped frame 5 are slidably connected;

[0019] When using this combined instrument temperature auxiliary calibration device, as Figures 1 - 3As shown, first, the cylindrical barrel 1 and the graphene thermal conductive foam 2 are nested and installed, and the cylindrical barrel 1 and the graphene thermal conductive foam 2 are bonded and fixed with thermal conductive glue to ensure the stability of the connection between the cylindrical barrel 1 and the graphene thermal conductive foam 2. Then, the U-shaped frame 5 is fitted with the edge of the constant temperature water-oil bath, and the threaded rod 6 is rotated. Through the threaded connection between the threaded rod 6 and the U-shaped frame 5, the position adjustment of the clamping plate 7 can be realized until the entire device is fixed between the clamping plate 7 and the U-shaped frame 5. At this time, the lower end of the cylindrical barrel 1 is immersed in the liquid in the constant temperature water-oil bath. When calibrating and detecting the temperature of the combined instrument body 3, the installation of the combined instrument body 3 can be realized by nesting the probe 301 with the round hole 201. With the thermal conduction of the cylindrical barrel 1, the graphene thermal conductive foam 2 and the thermal conductive glue, the liquid temperature in the constant temperature water-oil bath can be quickly transferred to the probe 301, and the reading can be carried out through the combined instrument body 3 to determine whether the temperature displayed by the combined instrument body 3 conforms to the liquid temperature in the constant temperature water-oil bath. If not, manual calibration can be carried out, thus completing the detection and calibration function of the combined instrument body 3. Moreover, the probe 301 on the combined instrument body 3 does not contact the liquid in the constant temperature water-oil bath during the whole process, thus avoiding later cleaning and excluding the interference factors before the combined instrument body 3 contacts the electrolyte, improving the product yield. This is the working principle of the temperature auxiliary calibration device for the combined instrument.

[0020] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
