Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0056] As Figures 1 to 7As shown, the embodiment of the present application provides a compact prepackaged transformer substation with monitoring function, comprising a transformer box body 1, a movable bearing seat 2, a transformer 3 and a monitoring assembly.

[0057] Specifically, the transformer box body 1 has an open end 4, and the open end 4 is used to load the movable bearing seat 2.

[0058] The movable bearing seat 2 is movably arranged on the inner bottom surface of the transformer box body 1, and is slidably arranged along the length direction of the transformer box body 1, and is fixedly connected with the inner wall of the transformer box body 1 after being moved into the transformer box body 1.

[0059] The transformer 3 is fixedly installed on the movable bearing seat 2, and is used to transform voltage, current and impedance.

[0060] The monitoring assembly is fixedly installed on the top of the transformer box body 1, has a circular motion track, and reciprocally swings along the vertical plane, and is used to comprehensively monitor the running state of the transformer 3.

[0061] In this embodiment, the circuit device such as the transformer 3 is installed on the movable bearing seat 2, and is fixedly connected with the inner wall of the transformer box body 1 after being pushed into the transformer box body 1, thereby ensuring the safety of the movable bearing seat 2.

[0062] When the circuit device such as the transformer 3 is working, the monitoring assembly is also working. The monitoring assembly moves in a circular manner around the circuit device such as the transformer 3, and simultaneously reciprocally swings in the vertical direction, thereby scanning and monitoring the circuit device such as the transformer 3, realizing comprehensive monitoring of the circuit device such as the transformer 3, and timely monitoring and early warning of the circuit device such as the transformer 3, thereby facilitating on-site personnel to make timely maintenance, and ensuring the safety of the prepackaged transformer substation.

[0063] In one specific embodiment, a moving guide rail 5 is fixedly arranged on the inner bottom surface of the transformer box body 1, a plurality of moving pulleys 6 are slidably arranged on the moving guide rail 5, and the plurality of moving pulleys 6 are fixedly installed on the bottom surface of the movable bearing seat 2. The movable bearing seat 2 can move along the moving guide rail 5, thereby facilitating maintenance and maintenance of the circuit device such as the transformer 3 on the movable bearing seat 2.

[0064] In addition, a lock core 7 is arranged outside the transformer box body 1 and penetrates the transformer box body 1, a lock rod 8 is arranged on the inner end of the lock core 7, a lock buckle 9 matched with the lock rod 8 is arranged on the movable bearing seat 2, and the lock rod 8 is connected with the lock buckle 9 through the rotation of the lock core 7.

[0065] Further, the monitoring assembly comprises a ring-shaped driving member, a vertical deflection member and a monitor 10.

[0066] Specifically, the ring-shaped driving member is arranged on the top of the transformer box body 1, and is used for driving the monitor 10 to make reciprocating ring-shaped movement around the transformer 3.

[0067] The vertical deflection member is fixedly arranged on the output end of the ring-shaped driving member, and is used for driving the monitor 10 to make reciprocating deflection movement in the vertical direction and scanning and monitoring the transformer 3 through the monitor 10.

[0068] The monitor 10 is fixedly arranged on the output end of the vertical deflection member, and is used for scanning and monitoring the transformer 3 through moving along the ring-shaped movement track and deflection in the vertical direction.

[0069] In the embodiment, the ring-shaped driving member surrounds the transformer 3 and other circuit devices, and drives the vertical deflection member to make ring-shaped movement above the transformer 3 and other circuit devices. In this process, the vertical deflection member drives the monitor 10 to make reciprocating deflection movement in the vertical direction, so that the monitor 10 can make real-time monitoring in the region inclined downward. Through mutual cooperation, the scanning and monitoring of the transformer 3 and other circuit devices are realized, local fault problems of the transformer 3 and other circuit devices can be monitored in time, and alarm can be given in time.

[0070] It should be noted that the monitor 10 can be, but is not limited to, an infrared sensor. The infrared sensor is used for making real-time monitoring on the local over-temperature condition of the transformer 3 and other circuit elements. When over-temperature fault in the transformer box body 1 is monitored, alarm can be given through the sound-light alarm and remote alarm, over-temperature fault in the transformer box body 1 can be obtained in time, and the fault in the transformer box body 1 can be processed in time.

[0071] Further, the ring-shaped driving member comprises a suspension rail 11, a suspension column 12, a disc-shaped telescopic rod 13 and a driving motor 14.

[0072] Specifically, the hanging rail 11 is fixedly installed on the top of the transformer box body 1, the hanging rail 11 has a ring-shaped moving track, and a movable groove 15 is formed through the bottom surface of the moving track.

[0073] The hanging column 12 is arranged on the moving track, and the hanging column 12 is in abutment and sliding contact along the inner wall of the moving track, and the bottom end of the hanging column 12 is arranged through the movable groove 15.

[0074] The disc-shaped telescopic rod 13 is rotationally installed on the top surface of the transformer box body 1, the disc-shaped telescopic rod 13 has a telescopic adjustable transmission radius, and the disc-shaped telescopic rod 13 is in transmission connection with the hanging column 12.

[0075] The driving motor 14 is fixedly installed on the top surface of the transformer box body 1, and the output shaft of the driving motor 14 penetrates the top surface of the transformer box body 1 and is in transmission connection with the disc-shaped telescopic rod 13, and the driving motor 14 is a servo motor.

[0076] In the embodiment, under the driving of the driving motor 14, the disc-shaped telescopic rod 13 rotates together with the rotating shaft of the driving motor 14. In the process of rotation, the disc-shaped telescopic rod 13 can drive the hanging column 12 to move in a ring shape along the moving track. In this process, the distance between the central axis of the hanging column 12 and the central axis of the driving motor 14 changes, the disc-shaped telescopic rod 13 can automatically adjust the transmission radius, and thus the stable operation of the ring-shaped driving member is ensured.

[0077] In a specific embodiment, as shown in Figure 7 The disc-shaped telescopic rod 13 includes a transmission disc 16, a positioning telescopic pipe 17 and a transmission connecting rod 18. The transmission disc 16 is rotationally installed on the top surface of the transformer box body 1, and the transmission disc 16 is in transmission connection with the driving motor 14. The positioning telescopic pipe 17 is fixedly installed on the side circumferential wall of the transmission disc 16, and a limiting sliding groove 20 is formed in the inner wall of the positioning telescopic pipe 17 along the length direction. The transmission connecting rod 18 is in abutment and sliding contact with the inner wall of the positioning telescopic pipe 17, a limiting protrusion 19 is arranged on the outer side wall of the transmission connecting rod 18, the limiting protrusion 19 is in sliding connection with the limiting sliding groove 20, a transmission groove 21 matched with the hanging column 12 is formed at the end of the transmission connecting rod 18, and the hanging column 12 is in transmission connection with the transmission groove 21.

[0078] In the movement of the disc-shaped telescopic rod 13, when the distance between the center axis of the hanging column 12 and the center axis of the driving motor 14 increases, the transmission connecting rod 18 is moved out of the positioning telescopic pipe 17 to stretch to match the movement of the hanging column 12. When the distance between the center axis of the hanging column 12 and the center axis of the driving motor 14 decreases, the transmission connecting rod 18 enters the inside of the positioning telescopic pipe 17 to contract to match the movement of the hanging column 12. Since the limiting sliding groove 20 and the limiting protrusion 19 are used for limiting between the positioning telescopic pipe 17 and the transmission connecting rod 18, the positioning telescopic pipe 17 and the transmission connecting rod 18 will not be separated, so that the stability of the disc-shaped telescopic rod 13 is ensured.

[0079] In addition, the hanging column 12 comprises a bearing disc 22, a hanging rod 24 and a moving ball 25. The bearing disc 22 is arranged in the moving track, and the bearing disc 22 is in close contact and sliding contact with the inner wall of the moving track. The hanging rod 24 is arranged through the bearing disc 22, the top of the hanging rod 24 is in transmission connection with the transmission groove 21, and the bottom end of the hanging rod 24 penetrates through the movable groove 15. The moving ball 25 is movably arranged on the bottom surface of the bearing disc 22, and the bottom surface of the bearing disc 22 is provided with a movable cavity matched with the moving ball 25.

[0080] It should be noted that the driving motor 14 is a servo motor, which can accurately control the rotating speed, so as to ensure that the detector can accurately monitor the circuit elements such as the transformer.

[0081] The hanging column 12 is supported by the bearing disc 22 and the hanging rail 11, and the moving ball 25 is arranged at the bottom of the bearing disc 22, so that the bearing disc 22 can move in the moving track. The bearing disc 22 and the moving ball 25 cooperate with each other and are driven by the disc-shaped telescopic rod 13, so that the vertical deflection member can move along the moving track in a ring shape, and the transformer 3 and other circuit devices can be comprehensively monitored.

[0082] Further, the vertical deflection member comprises a mounting table 26, a deflection frame 27, a transmission ball 28 and a driving member.

[0083] Specifically, the mounting table 26 is fixedly arranged at the bottom end of the hanging rod 24.

[0084] The deflection frame 27 is rotatably arranged on the bottom surface of the mounting table 26, and the monitor 10 is fixedly arranged at the end of the deflection frame 27 away from the mounting table 26.

[0085] The transmission ball 28 is fixedly arranged at the middle part of the deflection frame 27, and the transmission ball 28 is used to drive the deflection frame 27 to move in the vertical direction.

[0086] The driving member is arranged between the transformer box body 1 and the mounting table 26, and is used for driving the transmission ball 28 and the deflection frame 27 to perform deflection movement.

[0087] In the embodiment, as shown in Figure 4 and Figure 5 The driving member comprises a power rack 29, a driving shaft 30, a power gear 31 and a driving cam 32. The power rack 29 is fixedly arranged on the inner wall of the transformer box body 1. The driving shaft 30 is rotatably arranged on the bottom surface of the mounting table 26. The power gear 31 is fixedly arranged on the driving shaft 30, and is in meshing connection with the power rack 29. The driving cam 32 is fixedly arranged on the driving shaft 30, and is in sliding contact with the transmission ball 28.

[0088] In the embodiment, during the circular movement of the hanging column 12, the power gear 31 moves circularly along with the mounting table 26. Since the power rack 29 is in a fixed state, the power gear 31 drives the driving shaft 30 and the driving cam 32 to rotate during the movement of the power gear 31 along with the mounting table 26, so that double power output is realized under single motor driving.

[0089] During the rotation of the driving cam 32, since the driving cam 32 is in contact with the transmission ball 28, when the recessed area on the driving cam 32 is in contact with the transmission ball 28, the included angle between the deflection frame 27 and the vertical plane is minimum. When the protruding area on the driving cam 32 is in contact with the transmission ball 28, the included angle between the deflection frame 27 and the vertical plane is maximum. Under the reciprocating rotation of the driving cam 32, the deflection frame 27 drives the monitor 10 to perform reciprocating deflection movement between the minimum angle and the maximum angle, so that the scanning and monitoring of the circuit device such as the transformer 3 can be realized by cooperation with the circular driving member, and the accuracy of the monitoring result of the pre-installed transformer box is greatly improved.

[0090] In a specific embodiment, the driving cam 32 has a plurality of protrusions 33 and recesses 23, and the protrusions 33 and the recesses 23 are arranged at intervals and are uniformly distributed. When the protrusion 33 on the driving cam 32 is in contact with the transmission ball 28, the included angle between the deflection frame 27 and the vertical plane is maximum. When the recess 23 on the driving cam 32 is in contact with the transmission ball 28, the included angle between the deflection frame 27 and the vertical plane is minimum. During the rotation of the driving cam 32, the deflection frame 27 performs reciprocating deflection movement between the minimum angle and the maximum angle.

[0091] Compared with the prior art, the present application has at least the following beneficial effects:

[0092] The monitoring assembly of the present application has a circular motion track and can move circularly around the transformer, thereby monitoring the transformer in the circumferential direction. Meanwhile, the monitor can also perform reciprocating deflection motion in the vertical direction, and the combination of the two can realize circumferential scanning monitoring of the transformer, realize comprehensive real-time monitoring of the transformer, and can monitor and warn in the case of local abnormal temperature loss of the transformer, greatly improving the safety of the pre-installed transformer box, and having the characteristics of simple structure and convenient operation.

[0093] Further, the present application uses a single motor to drive the circular motion of the monitor, while also considering the reciprocating deflection motion in the vertical direction, saving hardware costs, and the single motor drive facilitates control of the motion state of the monitoring assembly.

[0094] The above is the preferred embodiment of the present application, and it should be noted that for ordinary skilled persons in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the scope of protection of the present application.
