TECHNICAL FIELD

[0001] The application belongs to the technical field of power transmission and transformation equipment, and particularly relates to an energy storage indicating structure of a spring operating mechanism. BACKGROUND

[0002] In order to enable users to conveniently and quickly know the energy storage state of a spring operating mechanism of a circuit breaker, and to avoid users from operating the mechanism in the energy storage state of the spring operating mechanism and causing personal injury, the existing spring operating mechanisms of the circuit breaker are generally provided with an energy storage indicating structure. At present, the energy storage indicating structure of the existing spring operating mechanism is generally connected with a main shaft in transmission and determines the energy storage state of the spring operating mechanism by means of rotation of the main shaft. For example, a high-voltage circuit breaker spring operating mechanism and a transmission device disclosed in a Chinese patent application for invention with the application publication number CN109786141A, wherein a closing spring cylinder is arranged below a mechanism support, an axis of the closing spring cylinder is arranged in a vertical direction, and an energy storage indicating structure is arranged at a side of the mechanism support.

[0003] However, when the circuit breaker is arranged in a three-phase side-by-side form, the spring operating mechanisms corresponding to the respective phases of the circuit breaker also need to be arranged side by side. At this time, the energy storage indicating plate of the above-mentioned energy storage indicating structure will be blocked by the adjacent spring operating mechanisms, resulting in that the energy storage state cannot be normally observed. In addition, some mechanisms also arrange the energy storage indicating structure at the side of the closing spring cylinder, such as a spring energy storage indicating device and a spring operating mechanism disclosed in a Chinese patent application for invention with the application publication number CN1097667932A and an electrical equipment and a spring operating mechanism thereof disclosed in a Chinese utility model patent with the authorization announcement number CN210467737U. In the above-mentioned CN1097667932A, the energy storage indicating structure includes a closing spring cylinder, a spring seat is arranged in the closing spring cylinder, a spring pull rod is connected to the spring seat, a guide seat is arranged on a cylinder wall of the closing spring cylinder, a sliding rod is guided and assembled on the guide seat in an axial direction of the closing spring cylinder, and a transmission member for driving the sliding rod to extend and retract is connected between the spring pull rod and the sliding rod to drive the sliding rod to act and point to different regions of an energy storage indicating plate.

[0004] However, since the energy storage indicating structures in the above-mentioned two mechanisms are arranged at the side of the closing spring cylinder, when the above-mentioned two mechanisms are arranged in a three-phase side-by-side form, the energy storage indicating plate will also be blocked by the adjacent spring operating mechanisms. SUMMARY

[0005] The application aims to provide an energy storage indicating structure of a spring operating mechanism to solve the problem that the energy storage indicating structure is easily blocked when the spring operating mechanisms are arranged side by side.

[0006] To achieve the above object, the spring operating mechanism energy storage indication structure in the application adopts the following technical scheme:

[0007] The spring operating mechanism energy storage indication structure comprises a closing spring cylinder, a spring seat arranged in the closing spring cylinder, and a spring pull rod connected to the spring seat; a guide seat is fixed to the wall of the closing spring cylinder, a slide rod is guided and assembled to the guide seat along the axial direction of the closing spring cylinder, and the slide rod is used to drive the energy storage pointer to point to different areas of the energy storage indication board; the energy storage indication structure further comprises a transmission member matched with the slide rod, and the transmission member is used to make the slide rod move along the axial direction of the closing spring cylinder together with the spring seat and the spring pull rod; the axis of the closing spring cylinder is arranged along the horizontal direction, the energy storage indication board is arranged at the rear end of the closing spring cylinder, and the surface of the energy storage indication board is parallel to the end surface of the rear end of the closing spring cylinder; a rotating shaft seat is arranged on the wall of the closing spring cylinder, a pointer rotating shaft for fixedly connecting the energy storage pointer is rotatably assembled to the rotating shaft seat; a swing rod is fixed to the pointer rotating shaft, a connecting rod is arranged between the swing rod and the slide rod, the two ends of the connecting rod are respectively hinged to the swing rod and the slide rod, and the connecting rod, the swing rod and the slide rod together constitute a crank slider mechanism, which is used to make the pointer swing to point to different areas of the energy storage indication board when the slide rod is guided to move.

[0008] The beneficial effects of the above technical scheme are as follows: when the spring operating mechanism starts to store energy, the movement of the slide rod along the axial direction of the closing spring cylinder can drive the connecting rod hinged to the slide rod to swing up and down, the other end of the connecting rod away from the slide rod is hinged to the swing rod, the swing rod is fixedly connected to the pointer rotating shaft rotatably assembled to the hinge shaft, and thus the up-and-down swinging of the connecting rod can drive the swing rod to swing up and down, the up-and-down swinging of the swing rod can drive the pointer rotating shaft to rotate, and the rotation of the pointer rotating shaft can drive the energy storage pointer connected to the pointer rotating shaft to swing up and down, so that the up-and-down swinging of the pointer can display the energy storage state of the spring operating mechanism on the energy storage indication board. Since the energy storage indication board in the application is arranged at the rear end of the closing spring cylinder with the axis arranged along the horizontal direction, and the surface of the energy storage indication board is parallel to the end surface of the rear end of the closing spring cylinder, the observation of the energy storage indication board is facilitated, and when the horizontally placed spring operating mechanism is arranged in a three-phase side-by-side form, the energy storage indication board will not be blocked by the adjacent spring operating mechanism, that is, the observation of the energy storage state of each spring operating mechanism is facilitated.

[0009] Further, the spring operating mechanism energy storage indication structure further comprises an indication board mounting seat for mounting the energy storage indication board, the indication board mounting seat and the rotating shaft seat are arranged in the horizontal direction perpendicular to the axis of the closing spring cylinder, and the energy storage indication board is located on the horizontal side of the slide rod; the energy storage pointer on the pointer rotating shaft and the swing rod are arranged in the axial direction of the pointer rotating shaft.

Meanwhile, the energy storage pointer and the swing rod are arranged in axial spacing along the pointer shaft, which can adapt to the position of the energy storage indicator, so that the energy storage pointer can be closer to the face of the energy storage indicator, which is beneficial to ensure the accurate indication position and facilitate the observation of the energy storage state.

[0011] Further, the two ends of the pointer shaft are rotatably connected with the shaft seat and the indicator mounting seat, respectively.

[0012] The beneficial effects of the above technical solutions are that the two ends of the pointer shaft are rotatably connected with the shaft seat and the indicator mounting seat, respectively. Thus, the stable rotation of the pointer shaft can be ensured through the joint action of the shaft seat and the indicator mounting seat, and the accuracy of the swing of the energy storage pointer can be ensured, that is, the accuracy of the display of the energy storage indication state is ensured.

[0013] Further, the energy storage pointer is arranged on the side of the indicator mounting seat away from the shaft seat.

[0014] The beneficial effects of the above technical solutions are that this is beneficial to shorten the length of the pointer shaft and reduce the space occupation in the horizontal direction.

[0015] Further, the indicator mounting seat comprises a vertical column fixed on the wall of the closing spring cylinder and a horizontal support rod fixed on the vertical column, the rear end of the horizontal support rod extends out of the rear end surface of the closing spring cylinder, and the energy storage indicator is fixedly connected with the rear end of the horizontal support rod.

[0016] The beneficial effects of the above technical solutions are that the energy storage indicator can be arranged behind the rear end surface of the spring cylinder through the horizontal support rod, so that the space at the rear end surface of the spring cylinder can be fully utilized, and the length of the slide rod can be shortened, which can avoid the bending deformation of the slide rod under stress and is beneficial to ensure the reliable operation of the crank and slide block mechanism.

[0017] Further, at least two horizontal support rods are arranged in the up-down direction, and the lowermost horizontal support rod has an up-down spacing with the lower edge of the energy storage indicator.

[0018] The beneficial effects of the above technical solutions are that the energy storage indicator is fixed by at least two transverse support rods, so that the energy storage indicator can be prevented from rotating with the transverse support rods, and the installation of the energy storage indicator is more stable. In addition, the lowermost transverse support rod is arranged close to the cylinder wall of the closing spring cylinder, and the lowermost transverse support rod and the lower edge of the energy storage indicator have an up-down interval, so that the energy storage indicator can be arranged relatively downward along the radial direction of the closing spring cylinder, that is, the space for arranging the energy storage indicator upward and downward is reduced, and the space occupation of the top of the closing spring cylinder is avoided.

[0019] Further, the energy storage indicator further comprises a reinforcing plate located at the back side of the energy storage indicator, each of the transverse support rods is fixedly connected with the energy storage indicator and the reinforcing plate, and the reinforcing plate has a downward extending part below the lowermost transverse support rod, and the downward extending part is fixedly connected with the energy storage indicator.

[0020] The beneficial effects of the above technical solutions are that the reinforcing plate fixed at the back side of the energy storage indicator can strengthen the strength of the connection between the energy storage indicator and the transverse support rods, and the downward extending part of the reinforcing plate can also strengthen the strength of the part of the energy storage indicator below the lowermost transverse support rod, that is, the strength of the energy storage indicator can be strengthened by the reinforcing plate, the bending deformation of the energy storage indicator caused by stress is reduced, and the stability of the installation of the energy storage indicator is increased.

[0022] The beneficial effects of the above technical solutions are that the position where the transverse support rod is fixedly connected with the energy storage indicator is arranged at the side of the indicating long hole close to the slide rod, so that the connection structure of the energy storage indicator and the transverse support rod can be prevented from interfering with the swing of the energy storage indicator, and the horizontal distance between the energy storage indicator and the slide rod is also reduced, the length of the pointer shaft is avoided from being too long, and the arrangement of the entire energy storage indicating structure is more compact.

[0023] Further, the energy storage indicator is of an L-shaped structure, and the energy storage indicator has a bent part bent to the energy storage indicator and away from the side of the slide rod.

[0024] The beneficial effects of the above technical solutions are that the bent part is corresponding to the indication of the energy storage indicator, so that the change of the energy storage state of the spring operating mechanism can be more conveniently observed, and the reading error of the energy storage state is reduced.

[0025] Further, the front end of the spring operating rod is a hinged end for the corresponding rod driving member to be hinged, one end of the transmission member is fixedly connected with the rear end of the spring operating rod, and the other end is provided with a slide rod penetrating hole or a slide rod penetrating slot for the slide rod to penetrate, the slide rod penetrating hole is a long hole, and the slide rod penetrating slot is a long slot, the length direction of the long hole or the long slot is perpendicular to the hinged axis of the hinged end to adapt to the swing of the spring operating rod; the slide rod is provided with two stop sheets respectively located on the front and rear sides of the transmission member and limiting matched with the front and rear sides of the transmission member, and the distance between the two stop sheets is greater than the size of the transmission member in the front and rear directions, so that the transmission member can drive the slide rod to move bidirectionally along the axial direction of the closing spring cylinder.

The long hole or the long slot arranged on the transmission member enables the connection between the transmission member and the slide rod to adapt to the swing of the closing spring operating rod, reduces the jamming of the connection between the transmission member and the slide rod caused by the swing of the closing spring operating rod, that is, the normal operation of the energy storage indicating structure is ensured. The stop sheets respectively located on the front and rear sides of the transmission member and limiting matched with the front and rear sides of the transmission member are arranged on the slide rod, so that the limiting match between the slide rod and the transmission member is ensured, and the slide rod is also facilitated to be driven by the transmission member to move bidirectionally along the axial direction of the closing spring cylinder.

[0039] The present invention is described in further detail below with reference to the examples.

[0040] Embodiment 1 of the energy storage indication structure of the spring operating mechanism of the present invention:

[0041] like Figure 5 and Figure 6 As shown in the figure, the spring operating mechanism is arranged in three phases in parallel. The energy storage indication structure of the spring operating mechanism of each phase is as follows: Figure 1 and Figure 2 As shown, the closing spring cylinder 10 is included, and the axis of the closing spring cylinder 10 is arranged in the horizontal direction.

[0042] like Figure 1 and Figure 2 As shown, a spring seat is provided in the closing spring cylinder 10, to which a spring pull rod 20 is connected. The front end of the spring pull rod 20 is a hinged end 21 for a pull rod driver (not shown in the figure). Through the hinged connection between the hinged end 21 and the corresponding pull rod driver, the pull rod driver can drive the spring pull rod 20 to operate. A rotating shaft seat 50 is fixed to the cylinder wall of the closing spring cylinder 10. A sliding rod 40 is mounted on the rotating shaft seat 50 along the axial direction of the closing spring cylinder 10. Figure 3 and Figure 4 As shown, the slide rod 40 includes a flat section 41 that cooperates with the rotating shaft seat 50 and is located at the front end of the slide rod 40, and a threaded section 42 that is located at the rear end of the slide rod 40. The flat section 41 and the rotating shaft seat 50 cooperate to prevent the slide rod 40 from rotating, and the rotating shaft seat 50 constitutes a guide seat for the slide rod 40.

[0043] like Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4As shown, the energy storage indicating structure of the spring operating mechanism further comprises a transmission member 30 matched with the slide rod 40, one end of the transmission member 30 is fixedly connected with the rear end of the spring pull rod 20, the other end is provided with a slide rod passing hole 31 through which the threaded section 42 of the slide rod 40 passes, and the threaded section 42 is threadedly fitted with two stop flaps 130 respectively located on the front and rear sides of the transmission member 30 and in limited cooperation with the front and rear sides of the transmission member 30 (as shown in Figure 3 and Figure 4 ). The distance between the two stop flaps 130 is greater than the size of the transmission member 30 in the front and rear directions. When the transmission member 30 moves back and forth along the axial direction of the closing spring cylinder 10 together with the spring pull rod 20, the transmission member 30 can drive the slide rod 40 to move back and forth along the axial direction of the closing spring cylinder 10 through the stop flaps 130, and the slide rod 40 moves together with the spring seat and the spring pull rod 20 along the axial direction of the closing spring cylinder 10. In addition, the slide rod passing hole 31 is a long hole, the length direction of the slide rod passing hole 31 is perpendicular to the hinge axis of the hinge end 21, and because the distance between the two stop flaps 130 is greater than the size of the transmission member 30 in the front and rear directions, the connection between the transmission member 30 and the slide rod 40 can be adapted to the swing of the spring pull rod 20 during the forward and backward movement through the slide rod passing hole 31, avoiding the connection between the transmission member 30 and the slide rod 40 being stuck, and ensuring the normal operation of the energy storage indicating structure.

[0044] As shown in Figure 1 and Figure 2 , the right part (the right part when looking from back to front in the direction parallel to the axial direction of the slide rod 40) of the rotating shaft seat 50 is rotatably fitted with a pointer rotating shaft 80 arranged perpendicularly to the slide rod 40, one end of the pointer rotating shaft 80 is fixedly connected with a swing rod 70 close to the rotating shaft seat 50, a connecting rod 60 is arranged between the swing rod 70 and the slide rod 40, both ends of the connecting rod 60 are hingedly connected with the swing rod 70 and the slide rod 40 respectively, and the slide rod 40, the connecting rod 60 and the swing rod 70 together constitute a crank slider mechanism, so that when the slide rod 40 moves back and forth along its own axial direction, the swing rod 70 can be driven to swing up and down through the connecting rod 60, and the pointer rotating shaft 80 can be driven to rotate through the up and down swing of the swing rod 70. In addition, as shown in Figure 2 , Figure 3 and Figure 4 , the hinge connection between the connecting rod 60 and the slide rod 40 is realized through a hinge shaft 160, a latch 140 perpendicular to the axial direction of the slide rod 40 is inserted into the slide rod 40 rearward of the position where the slide rod 40 is connected with the hinge shaft 160, and the latch 140 can limit the movement of the slide rod 40 along the axial direction of the closing spring cylinder 10, so as to avoid the slide rod 40 moving too much to cause interference between the rotating shaft seat 50 and the hinge shaft 160, causing damage to both, and further affecting the normal use of the energy storage indicating device.

[0045] As shown in Figure 1 and Figure 2As shown, the energy storage indicator structure of the spring operating mechanism also includes an indicator sign mounting seat, which is spaced apart from the shaft seat 50 in a horizontal direction perpendicular to the axis of the closing spring cylinder 10. The indicator sign mounting seat includes a column 90 fixed to the wall of the closing spring cylinder 10 and a transverse support rod 110 fixed to the column 90. The column 90 is spaced apart from the shaft seat 50. The other end of the pointer shaft 80, which rotates with the shaft seat 50, passes through the column 90 and rotates with the column 90. The pointer shaft 80 is provided with an energy storage pointer 100, which is spaced apart from the rocker arm 70 along the axis of the pointer shaft 80 and is located on the side of the column 90 away from the rocker arm 50. Furthermore, since the sliding rod 40 can rotate the pointer shaft 80 via the connecting rod 60 and the rocker arm 70 when it moves forward and backward along its own axis, the rotation of the pointer shaft 80 can cause the energy storage pointer 100 to swing in the up and down direction.

[0046] like Figure 1 and Figure 2 As shown, two transverse support rods 110 are fixed to the column 90 from top to bottom, and both transverse support rods 110 extend forward and backward. The energy storage indicator structure of the spring operating mechanism also includes an energy storage indicator sign 120. The energy storage indicator sign 120 is located on one side of the sliding rod 40 in the horizontal direction. The sign surface of the energy storage indicator sign 120 is parallel to the rear end face of the closing spring barrel 10. The energy storage indicator sign 120 is fixedly connected to the rear end of each transverse support rod 110. In this way, the energy storage indicator sign 120 can be installed on the cylinder wall of the closing spring barrel 10 through the transverse support rods 110 and the column 90. The rear ends of the two transverse support rods 110 extend beyond the end of the closing spring barrel 10, and there is a vertical gap between the lowest transverse support rod 110 and the lower edge of the energy storage indicator sign 120. This can reduce the vertical layout space of the energy storage indicator sign 120 and prevent the top space of the closing spring barrel 10 from being excessively occupied.

[0047] like Figure 1 and Figure 2As shown, the energy storage indicator 120 is provided with an indicating long hole 121 extending in the up-down direction, and the indicating long hole 121 is used for the energy storage indicator 100 to pass through, so that when the slide rod 40 is guided to move, the pointer can be swung to point to different areas of the energy storage indicator 120 through the above-mentioned crank slider mechanism. Since the energy storage indicator 100 is in an L-shaped structure, and the energy storage indicator 100 has a bent part bent to the energy storage indicator 120 and away from the slide rod 40, the energy storage indicator 120 is provided with an indicating scale 122, and the bent part is used for corresponding indication with the indicating scale 122 on the energy storage indicator 120, so that the energy storage state of the spring operating mechanism can be clearly displayed through the corresponding indication of the bent part and the indicating scale 122. And since the position where the transverse support rod 110 and the energy storage indicator 120 are fixedly connected is located on the side of the indicating long hole 121 close to the slide rod 40, so as to avoid the connection structure of the energy storage indicator 120 and the transverse support rod 110 from interfering with the swing of the energy storage indicator 100, and also helps to reduce the horizontal distance between the energy storage indicator 100 and the slide rod 40, avoid the length of the pointer shaft 80 being too long, so that the arrangement of the whole energy storage indication structure is more compact.

[0048] In addition, the energy storage indicator 120 also includes a reinforcing plate 150 located on the back side of the energy storage indicator 120, each transverse support rod 110 is fixedly connected with the energy storage indicator 120 and the reinforcing plate 150, and the reinforcing plate 150 has a lower extension part below the lowermost transverse support rod 110, and the lower extension part is fixedly connected with the energy storage indicator 120, so that through the reinforcing plate 150, the strength of the connection between the energy storage indicator 120 and the transverse support rod 110 can be strengthened, and the strength of the part of the energy storage indicator 120 below the lowermost transverse support rod 110 can also be strengthened, that is, the strength of the energy storage indicator 120 can be strengthened through the reinforcing plate 150, the bending deformation of the energy storage indicator 120 due to stress can be reduced, and the stability of the installation of the energy storage indicator 120 can be increased.

[0049] The working principle of the energy storage indication structure of the spring operating mechanism in the application is as follows:

[0050] When the spring operating mechanism is in the state of no energy storage, the spring pull rod 20 is located at the last end. When the spring operating mechanism starts to store energy, the spring pull rod 20 starts to move from back to front, and drives the transmission member 30 connected with the spring pull rod 20 to move, at the same time, the transmission member 30 drives the slide rod 40 to move from back to front along the axial direction of the slide rod 40, and then drives one end of the connecting rod 60 hinged with the slide rod 40 to move from back to front, so that the connecting rod 60 drives the hinged end of the swing rod 70 to move from up to down, and then the swing rod 70 drives the pointer shaft 80 to rotate clockwise (from right to left along the axial direction of the pointer shaft 80), and the clockwise rotation of the pointer shaft 80 drives the energy storage pointer 100 connected with the pointer shaft 80 to start to swing from down to up, so that the energy storage state of the spring operating mechanism can be clearly displayed on the energy storage indicator 120, thereby realizing the energy storage indication function of the spring operating mechanism.

[0051] The energy storage indicator of the energy storage indication structure in the application is arranged at the rear end of the closing spring cylinder arranged along the horizontal direction of the axis, and the surface of the energy storage indicator is parallel to the end surface of the rear end of the closing spring cylinder, so that the observation of the energy storage indicator is facilitated, and when the horizontally arranged spring operating mechanism is arranged in the form of three-phase parallel, the energy storage indicator will not be blocked by the adjacent spring operating mechanism, that is, the observation of the energy storage state of each spring operating mechanism is facilitated.
