Description

Technical Field

[0001] This utility model relates to the technical field of spring energy storage devices, specifically an energy storage indicator device for a three-phase linkage spring mechanism. Background Technology

[0002] The three-phase linkage circuit breaker spring operating mechanism is a new generation product developed and designed by our company in response to the requirements of the State Grid and market demands. The structure has been completely optimized, forming a new design concept with a symmetrical arrangement, offering advantages such as low transmission loss and high output power. It utilizes the energy stored in the opening and closing springs for opening and closing operations. When the closing spring is compressed and stores energy, the stored energy cannot be directly seen because the closing spring is internal; therefore, an energy storage indicator is needed to indicate the energy stored in the closing spring. Existing spring energy storage devices are used in double closing spring mechanisms for indication and transmission, typically connected to a spring rod or opening spring, thus reflecting the spring's stored energy. For single closing spring mechanisms, connections to these two devices can easily affect the normal operation of the closing device, and installation with them is more complex and difficult. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides an energy storage indicator device for a three-phase linkage spring mechanism.

[0004] The technical solution of this utility model is as follows:

[0005] An energy storage indicator device for a three-phase linkage spring mechanism is disclosed. The linkage spring mechanism includes a trip cylinder, a spring mechanism and a trip lever are disposed inside the trip cylinder, a support is provided at the upper end of the trip cylinder, and a gear is mounted on the support. A sleeve is mounted at the upper end of the trip lever, and the sleeve is eccentrically connected to the gear.

[0006] The indicating device includes a fixed plate mounted on a support, an indicating plate mounted on the side of the fixed plate, and an indicating sticker affixed to the front face of the indicating plate. An indicating arrow is connected to the back of the fixed plate via a sliding mechanism, and the indicating arrow extends to the front face of the indicating plate.

[0007] A connecting plate assembly is rotatably connected to the support via a pin, and the upper end of the connecting plate assembly is connected to the sliding mechanism via a steel wire rope, while the lower end extends to the gear end face.

[0008] The sliding mechanism is specifically designed as follows: the sliding mechanism includes two fixed seats that are vertically spaced apart and installed on the rear end face of the fixed plate, and a guide shaft is installed between the fixed seats, and a guide block is slidably installed on the guide shaft;

[0009] The indicator arrow is fixedly connected to the guide block, and the guide block is connected to the wire rope.

[0010] To facilitate the reset of the guide block, the guide shaft is fitted with a reset spring, which is located between any fixed seat and the guide block, with its two ends connected to the guide block and the fixed seat respectively.

[0011] To facilitate the guidance of the wire rope and improve the accuracy of energy storage testing, a guide pulley is installed on the top of the back of the fixing plate, and the wire rope passes around the guide pulley and connects to the guide block.

[0012] To facilitate the installation of the indicator arrow, a strip groove is provided on the fixing plate along the scale direction of the indicator sticker, and the indicator arrow passes through the strip groove and bends to extend to the indicator sticker.

[0013] The specific design of the indicator arrow is that the indicator arrow includes a fixing part fixed to the guide block, and the fixing part is connected to an indicator part perpendicular to it through the strip groove.

[0014] The connecting plate assembly is specifically designed as follows: the connecting plate assembly includes a first connecting plate and a second connecting plate, and the two are connected by a mounting cylinder, which is rotatably connected to a pin shaft.

[0015] The first connecting plate extends upward and is fixed to the wire rope, while the second connecting plate is arranged parallel to the gear and extends toward the end face of the gear.

[0016] To facilitate the movement of the connecting plate assembly, which in turn drives the wire rope, and ultimately the indicator plate indicates energy storage, the first and second connecting plates are arranged at an obtuse angle, with the end of the second connecting plate extending beyond the outermost end of the sleeve along the trajectory of the gear rotation. An integrally formed L-shaped bending plate is connected to the top of the first connecting plate, extending towards the fixing plate and used to fix the wire rope.

[0017] The beneficial effects of this utility model are as follows: This utility model is an energy storage indicator device for a three-phase linkage spring mechanism. This solution, by setting a sliding mechanism and a connecting plate assembly, allows the linkage mechanism to displace the connecting plate assembly through its own opening pull rod and sleeve when the circuit is opened. This displacement is then transmitted to the sliding mechanism via a wire rope, ultimately driving the indicator arrow to indicate energy storage. This facilitates the observation of energy storage in a single closing spring mechanism. The use of a sliding mechanism and connecting plate assembly in this solution facilitates the installation with the linkage mechanism. Moreover, the connecting plate assembly reacts quickly and does not generate excessive resistance to the movement of the linkage mechanism itself, ensuring the normal use of the linkage mechanism. Furthermore, the cooperation between the sliding mechanism and the wire rope makes the movement of the indicator arrow fast and accurate, more effectively utilizing the mechanism's transmission components to achieve energy storage indication of closing spring compression.

[0026] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0027] Example

[0028] This embodiment provides an energy storage indicator device for a three-phase linkage spring mechanism. See [link / reference] Figure 1 The linkage spring mechanism includes a gate cylinder 1, a spring mechanism 2 and a gate lever 3 inside the gate cylinder 1. A support 4 is provided at the upper end of the gate cylinder 1, and a gear 5 is installed on the support 4. A sleeve 6 is installed at the upper end of the gate lever 3. The sleeve 6 is eccentrically connected to the gear 5. After the spring mechanism 2 is energized, the spring first stores energy and drives the gate lever 3 to move. Under the drive of the gear 5, the gear 5 makes a clockwise circular motion, which in turn drives the eccentric sleeve 6 to rotate. The above is part of the structure of the linkage spring mechanism, which is the prior art. Other structural components can adopt the prior art and will not be described in detail. The indicating device of this solution has a connection and linkage relationship with the above-mentioned components. Therefore, only the components related to the indicating device in this solution are mentioned.

[0029] In this embodiment, the indicating device includes a fixing plate 7 mounted on the support 4. The fixing plate 7 is mounted on the top of the support 4, and the support 4 has two parts, one of which has a notch. The fixing plate 7 is mounted at the notch, and an indicating plate 8 is mounted on the side of the fixing plate 7. This side refers to... Figure 1 As shown on the left side, the front face of the indicator plate 8 is covered with an indicator sticker 9, which is the left side of the indicator plate 8. The back side of the fixed plate 7 is connected to an indicator arrow 11 through a sliding mechanism 10. The indicator arrow 11 extends to the front face of the indicator plate 8 and can extend to point to the indicator sticker 9. The sliding mechanism 10 can drive the indicator arrow 11 to move along the scale direction of the indicator sticker 9, thereby reflecting the energy storage status.

[0030] In this scheme, combined with Figure 4 The sliding mechanism 10 can drive the indicator arrow 11 to move. The sliding mechanism 10 includes two fixed seats 101 vertically spaced on the rear end face of the fixed plate 7, and a guide shaft 102 is installed between the fixed seats 101. That is, the guide shaft 102 is arranged in the vertical direction. A guide block 103 is slidably installed on the guide shaft 102. The sliding of the guide block 103 can drive the indicator arrow 11 to move. In order to facilitate the reset of the guide block 103, a reset spring 104 is sleeved on the guide shaft 102. The reset spring 104 is located between any fixed seat 101 and the guide block 103, and its two ends are connected to the guide block 103 and the fixed seat 101 respectively. The reset spring 104 can be installed on either side of the direction of movement of the guide block 103. When the guide block 103 moves, it squeezes or stretches the reset spring 104. After the external force is removed, the elastic force of the reset spring 104 drives the guide block 103 to reset.

[0031] Based on the above structure, the movement of the sliding mechanism 10 is mainly driven by the steel wire rope 14. The steel wire rope 14 is connected to the side of the guide block 103, and the steel wire rope 14 is connected to the tripping mechanism through the connecting plate assembly 13. The connecting plate assembly 13 is rotatably connected to the support 4 through the pin 12. The upper end of the connecting plate assembly 13 is connected to the steel wire rope 14, and the lower end extends to the end face of the gear 5. When the eccentrically mounted sleeve 6 rotates with the gear 5, it can push the connecting plate assembly 13 to rotate around the pin 12. Then, the upper end of the connecting plate assembly 13 generates a pulling force on the steel wire rope 14, thereby driving the guide block 103 to move.

[0032] Specifically, in combination Figure 2The connecting plate assembly 13 includes a first connecting plate 131 and a second connecting plate 132, which are connected by a mounting cylinder 133. The mounting cylinder 133 is rotatably connected to the pin 12. The first connecting plate 131 extends upward and is fixed to the wire rope 14. The second connecting plate 132 is arranged parallel to the gear 5 and extends towards the end face of the gear 5. It should be noted that the centers of the pin 12 and the gear 5 are staggered in the horizontal direction. The first connecting plate 131 and the second connecting plate 132 are arranged at an obtuse angle, that is, the first connecting plate 131 is inclined upward and away from the center of the gear 5. The inclined arrangement of the first connecting plate 131 can prevent it from rotating too fast or at too large an angle with the second connecting plate 132, which would cause the wire rope 14 to tilt too much and affect the test results. The end of the second connecting plate 132 extends beyond the outermost end of the sleeve 6 and follows the trajectory of the gear 5 as it rotates. The second connecting plate 132 is inclined towards the center of the gear 5. This allows the sleeve 6 to abut against the second connecting plate 132 during rotation. Because the second connecting plate 132 is arranged at an angle, the sleeve 6 can contact the end face of the second connecting plate 132 and apply a thrust. The rotation of the sleeve 6 causes the upper end of the first connecting plate 131 to move away from the indicator plate 8, thus moving the wire rope 14. Furthermore, to reduce the distance between the first connecting plate 131 and the indicator plate 8 and to facilitate applying a near-horizontal tension to the wire rope 14, an integrally formed L-shaped bending plate 134 is connected to the top of the first connecting plate 131. The L-shaped bending plate 134 extends towards the fixing plate 7 and is used to fix the wire rope 14. By setting the L-shaped bending plate 134, the distance between the first connecting plate 131 and the indicator plate 8 is shortened while the first connecting plate 131 is arranged at an angle, thereby reducing the length of the wire rope 14 and ensuring timely and rapid movement of the guide block 103, thus improving the accuracy of the test.

[0033] Based on the above structure, a guide pulley 105 is installed on the top of the back of the fixing plate 7, and the steel wire rope 14 passes around the guide pulley 105 and is connected to the guide block 103. By setting the guide pulley 105, the steel wire rope 14 can be guided to change direction, ensuring that the tension of the guide block 103 is in the vertical direction, and improving the stability and accuracy of the movement of the indicator arrow 11.

[0034] In addition, combined Figure 3The fixing plate 7 has a strip groove 15 along the scale direction of the indicator sticker 9, and the indicator arrow 11 passes through the strip groove 15 and bends to extend to the indicator sticker 9. Specifically, the indicator arrow 11 includes a fixing part 111 fixed to the guide block 103. By setting the fixing part 111, the entire indicator arrow 11 can move with the guide block 103. The fixing part 111 passes through the strip groove 15 and is connected to an indicator part 112 perpendicular to it. The indicator part 112 and the fixing part 111 are integrally formed by bending process. The indicator part 112 is in the form of an arrow and is located in the space covered by the indicator sticker 9. When moving with the guide block 103, the indicator part 112 can move along the scale direction of the indicator sticker 9. After the tension is fixed, the indicator part 112 stops moving to reflect the energy storage status of the spring mechanism 2.

[0035] Specifically, after the spring mechanism 2 is energized, the spring first stores energy. The spring drives the trip lever 3 to move. The sleeve 6, along with the trip lever 3, makes a clockwise circular motion under the action of the gear 5. After the sleeve 6 reaches a certain position, it contacts the second connecting plate 132 and continues to move. The sleeve 6 pushes the second connecting plate 132 to rotate upward around the pin 12, which in turn drives the first connecting plate 131 to rotate counterclockwise. This drives the steel wire rope 14 connected to the L-shaped bending plate 134. The steel wire rope 14 pulls the guide block 103 to move in a straight line, which in turn drives the indicator part 112 of the indicator arrow 11 to move in the direction of stored energy. At this time, the linkage mechanism is in the state of stored energy.

[0036] After receiving the closing signal, during the closing process, the spring mechanism 2 releases its spring force, causing the tripping lever 3 to move in the opposite direction to the tripping direction. At this time, the sleeve 6, along with the tripping lever 3, disconnects from the second connecting plate 132. The second connecting plate 132 has no supporting force, and the wire rope 14 has no traction force. Under the action of the return spring 104 on the guide shaft 102, the indicator part 112 of the indicator arrow 11 moves in the direction of no energy storage. At this time, the linkage mechanism is in the state of no energy storage.
