However, when the motor runs out of control and continues to rotate due to various reasons (such as circuit failures or software errors), the lack of a corresponding protection mechanism means that the continuous driving force can cause the motor to burn out due to overload. It can also damage the mechanical structures connected to the motor, such as gear wear and shaft breakage, severely affecting the normal use and lifespan of the horizon indicator, and increasing maintenance costs and downtime.

[0036] The following is combined with Figures 1-7 This invention describes the pitch mechanism and horizon gauge.

[0037] The pitch mechanism provided in this embodiment of the utility model includes: a fixed base 10, a dial 20, a slip component 30, and a drive component 40. The dial 20 is rotatably connected to the fixed base 10; the dial 20 is provided with a sliding groove 221; the slip component 30 includes a fixed member 31, a rotating member 32, and a lever 33. One end of the fixed member 31 is rotatably connected to the fixed base 10, the rotating member 32 is rotatably connected to the fixed member 31, and the lever 33 is disposed on the fixed member 31 and inserted into the sliding groove 221; the fixed end of the drive component 40 is connected to the fixed base 10, and the driving end of the drive component 40 is connected to the rotating member 32 to drive the rotating member 32 to rotate the dial 20, or to drive the rotating member 32 to rotate on its own.

[0038] like Figure 1 As shown, the fixed base 10 is the basic structural component of the pitch mechanism, providing support and stability for other components. The fixed base 10 has multiple mounting holes for easy connection with other components. The dial 20 is mounted on the fixed base 10 and connected to it via a rotatable connection, allowing the dial 20 to rotate around the fixed base 10. In one embodiment, the dial 20 includes a body 21 and a connector. One end of the connector is connected to the body 21, and the other end of the connector has a through hole. The fixed base 10 has mounting holes, and a pin passes through both the through hole and the mounting hole, achieving a rotatable connection between the dial 20 and the fixed base 10, allowing the dial 20 to rotate around the pin. A groove 221 can be provided on the connector, with the groove 221 extending in the same direction as the connector.

[0039] The slip-off assembly 30 includes a fixed member 31, a rotating member 32, and a lever 33. One end of the fixed member 31 is rotatably connected to the fixed base 10, and the fixed member 31 can rotate around the fixed base 10 under the action of an external force. The rotating member 32 is rotatably connected to the fixed member 31, and the rotating member 32 can rotate around the fixed member 31 under the action of an external force. The lever 33 is located on the fixed member 31 and inserted into the groove 221 on the dial 20, and can move along the extension direction of the groove 221 to drive the dial 20 to rotate.

[0040] The drive assembly 40 includes a fixed end and a drive end. The fixed end of the drive assembly 40 is connected to the fixed base 10 to ensure the stability of the drive assembly 40 during operation. The drive end of the drive assembly 40 is connected to the rotating member 32. With the power provided by the drive assembly 40, the rotating member 32 is driven to rotate around the fixed member 31, or the rotating member 32 drives the fixed member 31 and the dial 20 to rotate. Specifically, when the driving force of the drive assembly 40 is less than the frictional force between the rotating part 32 and the fixed part 31, the drive assembly 40 drives the rotating part 32 to rotate the fixed part 31. During the rotation, the lever 33 moves within the slide groove 221, causing the dial 20 to rotate by a certain angle. When the driving force of the drive assembly 40 is greater than the frictional force between the rotating part 32 and the fixed part 31, the drive assembly 40 drives the rotating part 32 to rotate around the fixed part 31. At this time, the fixed part 31 and the dial 20 do not rotate. In the event of a loss of control of the drive assembly 40, the drive assembly 40 and the structures connected to it, such as the fixed part 31 and the dial 20, are protected, thereby extending the life of the level gauge. The rotating part 32 can be a gear or other rotatable components under external force.

[0041] The pitch mechanism provided in this embodiment of the utility model has a slip component 30 between the drive component 40 and the dial 20. The drive end of the drive component 40 is connected to the rotating component 32. When the driving force of the drive component 40 is less than the friction between the rotating component 32 and the fixed component 31, the slip component 30 rotates, and the lever 33 drives the dial 20 to rotate, thereby adjusting the rotation angle of the dial 20. When the driving force of the drive component 40 is greater than the friction between the rotating component 32 and the fixed component 31, the rotating component 32 rotates on its own, preventing damage to the fixed component 31 and the dial 20 due to the loss of control of the drive component 40, reducing the maintenance of the level gauge, and extending the service life of the level gauge.

[0042] The drive assembly 40 includes a motor 41 and a first gear 42. The fixed end of the motor 41 is connected to the fixed base 10, and the driving end of the motor 41 is connected to the first gear 42. Starting the motor 41 drives the first gear 42 to rotate. The motor 41 may include an electric motor, a hydraulic device, etc. In one embodiment, the rotating member 32 includes a second gear 321, and the fixing member 31 includes an abutment portion 311 and a insertion portion 312, such as... Figure 5As shown, the abutment portion 311 and the insertion portion 312 are connected. The insertion portion 312 extends away from the abutment portion 311. The second gear 321 is sleeved on the insertion portion 312 and abuts against the abutment portion 311. There is friction between the second gear 321 and the abutment portion 311. When the external force is less than the friction between them, the second gear 321 and the fixing member 31 rotate simultaneously. When the external force is greater than the friction between them, the second gear 321 rotates around the insertion portion 312. Figure 2 and Figure 3 As shown, the first gear 42 and the second gear 321 are externally meshed. When the motor 41 starts, it drives the first gear 42 to rotate the second gear 321. When the driving force of the motor 41 is less than the frictional force between the second gear 321 and the fixing member 31, the angle of the dial 20 is adjusted. When the motor 41 malfunctions and the driving force is greater than the frictional force between the second gear 321 and the fixing member 31, the second gear 321 rotates on its own, protecting the fixing member 31 and the dial 20. It should be noted that when the external force is less than the frictional force between the fixing member 31 and the second gear 321, their relative positions remain unchanged. The position between them can be limited by fasteners, such as limit pins.

[0043] like Figure 4 and Figure 5 As shown, the slippage assembly 30 also includes a lever seat 37. The two end faces of the second gear 321 are respectively in contact with the fixing member 31 and the lever seat 37. There is friction between the second gear 321 and the fixing member 31, and there is friction between the second gear 321 and the lever seat 37. In one embodiment, the fixing member 31 includes an abutment portion 311 and an insertion portion 312, which are connected. The second gear 321 and the lever seat 37 are both provided with insertion holes. The second gear 321 and the lever seat 37 are sequentially inserted into the insertion portion 312. The two end faces of the second gear 321 are in contact with the end faces of the abutment portion 311 and the lever seat 37, respectively. When the external force is greater than the frictional force, the second gear 321 rotates; when the external force is less than the frictional force, the second gear 321, the fixing member 31, and the lever seat 37 rotate simultaneously. In one embodiment, the lever 33 is disposed on the lever seat 37. When the second gear 321, the fixing member 31 and the lever seat 37 rotate, the lever 33 can move along the extension direction of the slide groove 221, thereby driving the dial 20 to rotate.

[0044] To further limit the friction between the second gear 321 and the fixing member 31, and the friction between the second gear 321 and the lever seat 37, the slippage assembly 30 in this embodiment of the invention also includes a limiting member 34. The limiting member 34 is connected to the fixing member 31 and is located on the side of the lever seat 37 away from the second gear 321, used to limit the position of the lever seat 37, thereby limiting the position of the second gear 321. In one embodiment, the insertion part 312 is provided with a limiting hole, and the limiting member 34 is inserted into the limiting hole, thereby limiting the position of the lever seat 37.

[0045] like Figure 4 , Figure 6 and Figure 7 As shown, the slippage assembly 30 also includes a compression spring 35 and a locking member 36. The compression spring 35 is pressed onto the side of the lever seat 37 away from the second gear 321, and the locking member 36 is located on the side of the compression spring 35 away from the lever seat 37. The locking member 36 is connected to the fixing member 31 to adjust the pressure of the compression spring 35. In one embodiment, the compression spring 35 is sleeved on the insertion part 312, and the locking member 36 can be threadedly connected to the fixing member 31. By rotating the locking member 36, the compression spring 35 is pressed onto the end face of the lever seat 37 away from the second gear 321, and the pressure of the compression spring 35 is adjusted, thereby adjusting the pressure of the second gear 321. According to mechanical relationships, the greater the pressure on the second gear 321, the greater the friction between the second gear 321 and the fixing member 31, and between the second gear 321 and the lever seat 37, and the less likely the second gear 321 is to slip. It should be noted that before installation, the pressure applied to the compression spring 35 is calculated in advance so that the second gear 321 can drive the dial 20 to rotate. At the same time, when the dial 20 rotates to its limit, the motor 41 continues to rotate, and the second gear 321 begins to slip.

[0046] The pitch mechanism provided in this embodiment of the utility model also includes an encoder 50. The fixed end of the encoder 50 is connected to the fixed base 10, and the driving end of the encoder 50 is connected to the fixing member 31. During the rotation of the slip component 30, the output shaft of the encoder 50 will be driven to rotate. The encoder 50 can record the rotation angle and calculate the pitch angle of the scale 20.

[0047] In actual operation, when motor 41 drives the first gear 42 to rotate, the first gear 42 drives the second gear 321 to rotate. The second gear 321 drives the fixed part 31 and the lever seat 37 to rotate through friction. During the rotation, the lever 33 moves within the slide groove 221, thereby driving the scale 20 to rotate. Under normal conditions, when encoder 50 detects that the scale 20 has rotated to its limit position (e.g., ...), ... Figure 2 and Figure 3In the case shown, the control system stops the motor 41 from rotating. In the case of control system failure, the dial 20 is at its limit position. Since the driving force of the motor 41 is greater than the friction force on both ends of the second gear 321, the second gear 321 begins to slip (rotate). At this time, the motor 41 can continue to rotate to avoid the motor 41 burning out due to overload. At the same time, until the lever 33 is at its limit, the friction force on both ends of the second gear 321 is insufficient to drive the entire slipping assembly 30 to rotate, thus avoiding structural damage.

[0048] In one embodiment, the mounting base 10 includes a first mounting member 11 and a second mounting member 12, the first mounting member being connected to the second mounting member 12, the dial 20 being rotatably connected to the first mounting member 11, and a drive assembly 40 being connected to the second mounting member 12, the rotation axis of the drive assembly 40 being parallel to the rotation axis of the dial 20. Figure 1 As shown, the first mounting component 11 and the second mounting component 12 are vertically connected.

[0049] The dial 20 includes a body 21 and a first connector 22. One end of the first connector 22 is connected to a first side of the body 21, and the other end of the first connector 22 is rotatably connected to a first side of the first mounting member 11. A slide groove 221 is provided on the first connector 22 and extends along the extending direction of the first connector 22.

[0050] Furthermore, the dial 20 may also include a second connector 23, one end of which is connected to the second side of the body 21, and the other end of which is rotatably connected to the second side of the second mounting member 12. The first connector 22 and the second connector 23 are arranged in parallel. In one embodiment, the first side and the second side of the body 21 are symmetrically arranged.

[0051] This utility model embodiment also provides a horizon meter, including the pitch mechanism as described in any of the above embodiments.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
