Common monitoring methods include using sensors such as high-frequency radar level gauges and ultrasonic level gauges. However, these common sensors cannot function properly in harsh environments such as high humidity, high smoke and dust, and high viscosity. Therefore, how to achieve material level monitoring in harsh environments is a technical problem that urgently needs to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic level gauge that can monitor materials in harsh environments.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows: This application provides a magnetic level gauge, including a base, a passive rotating part, an active rotating part, and a resistance component.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] See Figure 1 and Figure 2 This application provides a magnetic level gauge, including a base 3, a passive rotating part 2, an active rotating part 1, and a resistance component. The passive rotating part 2 is rotatably connected to the base 3 and is provided with a first magnetic unit. The active rotating part 1 is spaced apart from the passive rotating part 2 and is provided with a second magnetic unit; the first magnetic unit and the second magnetic unit cooperate to cause the active rotating part 1 to drive the passive rotating part 2 to rotate, and the resistance component is connected to the passive rotating part 2.

[0023] The base 3 is used to fix the passive rotating part 2. For example, when the level gauge of the present application embodiment is applied to the silo, the passive rotating part 2 can be rotatably connected to the silo by connecting the base 3 to the silo.

[0024] The active rotating part 1 is an active rotating component, and the passive rotating part 2 is a driven rotating component.

[0025] The rotation axes 6 of the active rotating part 1 and the passive rotating part 2 can be parallel or perpendicular.

[0026] The first and second magnetic units are magnetic structures.

[0027] The arrangement of the first magnetic unit on the active rotating part 1 and the arrangement of the second magnetic unit on the passive rotating part 2 can be selected from existing arrangements. For example, a conventional magnetic coupler can be used, which includes an active part and a driven part. The first magnetic unit can be set according to the magnet of the driven part, and the second magnetic unit can be set according to the magnet of the active part.

[0028] The resistance component is connected to the passive rotating part 2, so that the resistance component can rotate together with the passive rotating part 2.

[0029] Under the action of the first and second magnetic units, the active rotating part 1 and the passive rotating part 2 can be connected by air-to-ground transmission. On the one hand, this increases the adaptability of the magnetic level gauge of this embodiment to harsh environments. For example, when used in harsh environments, the active rotating part 1 and its drive structure can be placed in a closed chamber to prevent the external environment from affecting the normal operation of the active rotating part 1 and its drive structure. On the other hand, it allows the passive rotating part 2 to stop rotating while the active rotating part 1 continues to rotate, thereby enabling the resistance component to monitor the material.

[0030] The rotation of the resistance component determines the material level. For example, when the material level reaches the resistance component, it is blocked from rotating by the material. Conversely, when the material level drops, the material is no longer in contact with the resistance component, allowing it to rotate normally. Compared to traditional sensors, the resistance component has the advantages of simple and reliable structure, making it suitable for harsh environments.

[0031] It may also include a detection component for detecting the rotation of the passive rotating part 2, thereby indicating the material level status. For example, the detection component may include a sensor and a processor. The sensor can be selected from existing products. The sensor and processor are electrically connected so that the rotation status of the passive rotating part 2 can be detected by the sensor. The specific circuit of the electrical connection between the sensor and the processor, the working principle of the sensor, and the code of the processor controlling the operation of the sensor are well known to those skilled in the art and will not be described in detail here.

[0032] In some embodiments, a driving component 5 is further included, the output end of which is connected to the active rotating part 1 via a transmission connection.

[0033] The drive component 5 may include a motor, the output of which is connected to the active rotating part 1. Alternatively, it may include a motor and a reducer, the output of which is connected to the input of the reducer, and the output of which is connected to the active rotating part 1.

[0034] The drive component 5 can drive the active rotating part 1 to rotate.

[0035] In this embodiment, the active rotating part 1 can be sleeved on the output end of the driving component 5. Along the axial direction of the output end of the driving component 5, the output end can be provided with a threaded hole. When the active rotating part 1 is sleeved on the output end, a bolt is used to thread it into the threaded hole of the output end. The bolt can increase the radial dimension of the output end, thereby enabling the active rotating part 1 to be fixed on the output end of the driving component 5.

[0036] In some embodiments, the base 3 is connected to the drive component 5.

[0037] The base 3 is connected to the drive component 5, which increases the integration of the device and makes it easier to fix the relative positions of the active rotating part 1 and the passive rotating part 2.

[0038] In some embodiments, the system further includes a cover 4, which covers the base 3, and the passive rotating part 2 and the active rotating part 1 are disposed within the space enclosed by the cover 4 and the base 3.

[0039] The space enclosed by the cover 4 and the base 3 can protect the active rotating part 1 and the driven rotating part, thereby improving the adaptability of the magnetic level gauge of this application embodiment to harsh environments.

[0040] A sealing part may be provided between the cover 4 and the seat 3.

[0041] The cover 4 can be connected to the base 3 by bolts.

[0042] In some embodiments, a drive component 5 is also included, the cover 4 is provided with a transmission hole, the output end of the drive component 5 is connected to the active rotating part 1 via the transmission hole, and the cover 4 is connected to the drive component 5.

[0043] The transmission hole allows the output end of the drive component 5 to penetrate into the space enclosed by the seat 3 and the cover 4 and connect with the active rotating part 1.

[0044] The cover 4 can be connected to the housing of the drive component 5.

[0045] The cover 4 is connected to the drive component 5. On the one hand, this increases the integration of the device. On the other hand, the drive component 5 can be used to close the transmission hole, thereby increasing the sealing performance of the cover 4.

[0046] In some embodiments, the cover 4 is provided with an inspection hole.

[0047] The inspection hole is used for inspection of the inside of the cover 4. For example, the active rotating part 1 and the passive rotating part 2 can be inspected through the inspection hole without disassembly.

[0048] The access hole can be detachably equipped with a plug.

[0049] In some embodiments, a rotating shaft 6 is further included, which is rotatably connected to the base 3. Along the axial direction of the rotating shaft 6, a resistance member is connected to one side of the rotating shaft 6, and a passive rotating part 2 is connected to the other side of the rotating shaft 6.

[0050] The passive rotating part 2 is connected to the rotating shaft 6, so that the passive rotating part 2 can rotate relative to the base 3.

[0051] The passive rotating part 2 and the resistance part are respectively located on different sides of the rotating shaft 6, so that the passive rotating part 2 can be as far away from the resistance part as possible, reducing the impact of the harsh environment in which the resistance part is located on the passive rotating part 2 and the active rotating part 1, and improving the adaptability of the device to harsh environments.

[0052] In this embodiment, the base 3 is provided with a shaft hole, and a bearing 7 is provided in the shaft hole. The rotating shaft 6 can pass through the inner ring of the bearing 7.

[0053] Multiple bearings 7 can be arranged side by side along the axial direction of the rotating shaft 6.

[0054] In some embodiments, the passive rotating part 2 is provided with a connecting hole 11, the rotating shaft 6 passes through the connecting hole 11, the rotating shaft 6 is provided with a shoulder, the shoulder forms a first surface 12, the first surface 12 abuts against one side of the passive rotating part 2, and the rotating shaft 6 is connected to abutting part 10, the abutting part 10 abuts against the other side of the passive rotating part 2.

[0055] Connection hole 11 is used for connecting the rotating shaft 6.

[0056] The shoulder can be formed by reducing the diameter of one end of the shaft 6 that is inserted into the connecting hole 11.

[0057] The first surface 12 abuts against the passive rotating part 2 and is used to limit the axial position of the passive rotating part 2 on the rotating shaft 6.

[0058] The abutment 10 can be a bolt, and correspondingly, the rotating shaft 6 can be provided with a shaft hole. The abutment 10 and the first surface 12 cooperate to fix the passive rotating part 2 in the axial position of the rotating shaft 6.

[0059] In some embodiments, the resistance component includes a resistance blade 8 and a rod 9, with the rod 9 connected to the passive rotating part 2 and the resistance blade 8 connected to the rod 9.

[0060] The resistance vane 8 is used for material level detection; that is, when material comes into contact with the resistance vane 8, the resistance vane 8 cannot rotate.

[0061] The lever 9 can be used to adjust the position of the resistance blade 8 relative to the base 3.

[0062] In some embodiments, the rod 9 is hollow inside.

[0063] The rod 9 is hollow inside, which can reduce the weight of the rod 9. On the other hand, the rod 9 can be used to install the resistance blade 8. For example, the shaft 6 can be inserted into the rod 9 so that the rod 9 can be connected to the shaft 6.

[0064] In this embodiment, the resistance blade 8 can be sleeved on the outer periphery of the rod 9. The resistance blade 8 and the rod 9 can each be provided with mounting holes. A limiting member is inserted through the mounting holes of both, so that the resistance blade 8 can be fixed to the rod 9.
