Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage switch cabinets, and in particular to a portable external intelligent high-voltage switch cabinet electric operation device and method. Background Art

[0002] In the power system, high-voltage switchgear is an important electrical equipment, and its operating device is usually fixed, requiring a lot of space and relatively complicated operation. Although the traditional high-voltage switchgear electric operating device can meet the operation requirements of the high-voltage switchgear, it has certain limitations, such as large equipment size, inconvenient installation and transportation, and inability to adapt to the use requirements of different sites. In practical applications, especially in field environments and compact spaces, traditional equipment is bulky and difficult to carry.

[0003] Chinese patent announcement number CN221428361U discloses: a portable outdoor switch cabinet, including a cabinet body, a switch cabinet bottom plate fixedly installed at the bottom of the cabinet body, an electric lifting rod arranged on the lower surface of the switch cabinet bottom plate, and one end of the electric lifting rod away from the switch cabinet bottom plate is connected to the upper surface of a movable plate, and a moving wheel is rotatably installed on the lower surface of the movable plate. By adopting the above technical solution, the moving wheel is arranged inside the cabinet body, and will not occupy additional space when it is not needed to be moved. The setting of the electric lifting rod can lift the cabinet body, revealing the moving wheel, thereby realizing the movement of the switch cabinet.

[0004] The above solution makes the switch cabinet easy to move, but when it is installed in the wild or in a compact space, the switch cabinet is still a whole and has a large volume. Some switch cabinets need to be installed at a high place, such as an external high-voltage switch cabinet. During the installation process, the switch cabinet needs to be hoisted. However, since the switch cabinet is an integrated design, the safety of the hoisting operation is poor. It is difficult to locate the specific installation position of the switch cabinet when performing hoisting operations in the wild or in a compact space. Summary of the invention

[0009] Preferably, a rack is provided on the lifting frame along its height direction and moves synchronously with the lifting frame, and the rack meshes with the gear when the lifting frame rises.

[0010] Preferably, the meshing teeth on the rack are all arranged to be inclined upward, and when the rack descends with the lifting frame, the rack and the gear are slidably matched, and when the rack rises with the lifting frame, the rack and the gear are meshed with each other.

[0011] Preferably, a sliding groove is horizontally opened on the lifting frame, and the rack is slidably arranged in the sliding groove along the extension direction of the sliding groove. A first spring is arranged between the rack and the bottom of the sliding groove along the moving direction of the rack, and the two ends of the first spring are respectively fixedly connected to the sliding groove and the rack.

[0012] Preferably, a screw rod is rotatably arranged in the rotating frame along the height direction of the rotating frame, the screw rod passes through the lifting frame and cooperates with the lifting frame thread, and a driving unit for driving the screw rod to rotate is arranged on the upper part of the screw rod.

[0014] Preferably, a liquid inlet pipe and a liquid outlet pipe are vertically arranged on the upper part of the rotating frame, a liquid inlet port and a liquid outlet are arranged on the switch cabinet body, the liquid inlet pipe and the liquid outlet pipe are connected to the liquid inlet port and the liquid outlet respectively, and two reversing valves are arranged on the driving circuit, the two reversing valves are respectively located on both sides of the water pump and are respectively connected to the liquid inlet pipe and the liquid outlet pipe.

[0015] The present invention also relates to a portable external intelligent high-voltage switch cabinet electric operation method, using a portable external intelligent high-voltage switch cabinet electric operation device, the specific steps are as follows: S1. The mounting frame is fixed at the designated position, and the rotating frame is self-corrected to a vertical state through its own low center of gravity; S2. The lifting frame descends from the rotating frame. When the lifting frame descends to the lowest position, the switch cabinet body is placed on the lifting frame, and the lifting frame drives the switch cabinet body to rise into the rotating frame; S3. When the lifting frame rises into the rotating frame, the rotating frame and the extension column arranged on the mounting frame no longer rotate relative to each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a mounting frame so that when installing, the mounting frame is first fixedly arranged at a designated position, an extension column is fixedly arranged on the mounting frame, and the rotating frame is hinged on the extension column, so that the center of gravity of the rotating frame is lower than the extension column, so that the rotating frame can realize self-correction through its own center of gravity, thereby improving the installation efficiency.

At the same time, after the switch cabinet body and the lifting frame are separated, when the mounting frame is installed, the total weight of the mounting frame provided with the rotating frame and the lifting frame is lower than the total weight of the entire high-voltage switch cabinet, so that it is more convenient to install the mounting frame at a high place. At the same time, the lifting frame provided on the rotating frame can automatically descend when the rotating frame is at a high place, so that the staff can move the switch cabinet body to the lifting frame without hoisting the switch cabinet body. 2. By setting the gear and the rack, and making the meshing teeth on the rack tilt upward, when the rack descends with the lifting frame, when the rack passes one side of the gear, the rack slides into the sliding groove under the action of the gear, and the first spring is squeezed. When the rack completely passes the gear, the first spring returns to its original position. When the switch cabinet body is placed in the lifting frame, the lifting frame drives the switch cabinet body to rise, and the rack rises synchronously with the lifting frame. The rising rack meshes with the gear and drives the gear to rotate, so that the gear presses the rubber ring, thereby increasing the friction coefficient between the mounting frame and the rotating frame, ensuring that after the lifting frame drives the switch cabinet body to rise completely into the rotating frame, the rotating frame will not swing around the extension column; 3. By setting the driving unit of the present invention, the lifting frame can be lifted and lowered, and the high-voltage switch cabinet can be cooled during normal operation, thereby preventing the lifting frame from being idle.

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1-Figure 4 and Figure 7 : A portable external intelligent high-voltage switch cabinet electric operating device, including a mounting frame 1, an extension column 11 is horizontally fixedly arranged on the mounting frame 1, a rotating frame 2 is arranged on one side of the mounting frame 1, the extension column 11 horizontally penetrates the rotating frame 2 and rotates with the rotating frame 2, the straight-line distance from the lower end of the rotating frame 2 to the extension column 11 is greater than the straight-line distance from the upper end of the rotating frame 2 to the extension column 11, and a lifting frame 21 for receiving the switch cabinet body 3 is arranged in the rotating frame 2 and moves along the height direction of the rotating frame 2.

[0021] Most of the existing high-voltage switchgears are of integral structure and large in size. When installing, the high-voltage switchgear is mostly set on the ground. However, with the expansion of the application field, some high-voltage switchgear needs to be set at high places, and in many cases, the high-voltage switchgear needs to be transported to mountainous areas, and the integral high-voltage switchgear is difficult to transport. The existing way to improve the transportation efficiency is to set moving wheels under the high-voltage switchgear. However, if the high-voltage switchgear needs to be installed on a hillside, the range of the high-voltage switchgear with moving wheels is not easy to transport. The high-voltage switchgear that needs to be set at a high place is mainly composed of a mounting structure and a switchgear body 3. In the existing transportation method, the mounting structure and the switchgear body 3 are usually transported separately, which reduces The pressure during transportation is reduced. At the same time, when installing the high-voltage switchgear, the mounting structure can be pre-installed first, and then the switchgear body 3 can be placed on the mounting structure. However, in order to ensure the stability of the switchgear body 3 when it is placed, the existing mounting structure needs to be positioned at the installation position of the mounting structure so that the upper end surface of the mounting structure that supports the switchgear body 3 is in a horizontal state. At the same time, the existing mounting structure itself does not have a lifting function. The weight of the switchgear body 3 is much greater than the weight of the mounting structure. When placing the switchgear body 3 on the mounting structure, lifting equipment is required. When lifting in mountainous areas, the erection of the lifting equipment is difficult and is greatly affected by the terrain, which has limitations.

[0022] In order to avoid the occurrence of the above situation, the structure of the existing portable external high-voltage switchgear is optimized so that the high-voltage switchgear is convenient for transportation and installation. The specific structure and working process of the high-voltage switchgear of the present invention are as follows: During use, the mounting frame 1 is first fixed at the specified position, and the rotating frame 2 is hinged on the extension column 11. Since the distance from the lower end of the rotating frame 2 to the extension column 11 is greater than the distance from the upper end of the rotating frame 2 to the extension column 11, the center of gravity of the rotating frame 2 rotatably set on the extension column 11 is located below the extension column 11. Therefore, when the mounting frame 1 is fixed to the specified position, there is no need to determine the horizontal state of the mounting frame 1, that is, when installing the mounting frame 1, there is no need to determine the horizontal state of the mounting frame 1 by a spirit level before installing it, even if the mounting frame 1 is tilted at a certain angle, the tilt at a certain angle means that the installer perceives the mounting frame 1 as being installed in a horizontal state through the naked eye, while the actual mounting frame 1 is tilted to a certain extent. After the mounting frame 1 is fixedly set at the designated position, the rotating frame 2 set on the extension column 11 rotates to a vertical state under the action of its own center of gravity. When the rotating frame 2 no longer rotates around the extension column 11, the lifting frame 21 set on the rotating frame 2 descends along the height direction of the rotating frame 2. When the lifting frame 21 descends to the lowest position, the switch cabinet body 3 is pushed into the lifting frame 21. After confirming that the switch cabinet has completely entered the lifting frame 21, the lifting frame 21 rises along the height direction of the rotating frame 2. When the lifting frame 21 completely enters the rotating frame 2, the rotating frame 2 and the extension column 11 no longer rotate relative to each other, and the installation of the high-voltage switch cabinet is completed. When the lifting frame 21 enters the rotating frame 2, the rotating frame 2 and the extension column 11 no longer rotate, which can prevent the external wind from shaking the rotating frame 2 left and right when it flows through the rotating frame 2, thereby ensuring that the switch cabinet body 3 set on the lifting frame 21 can work stably. The process of stopping the rotation between the rotating frame 2 and the extension column 11 due to the rise of the lifting frame 21 will be described later.

[0023] By setting the mounting frame 1, the mounting frame 1 is first fixedly set at the designated position during installation, the mounting frame 1 is fixedly set with an extension column 11, the rotating frame 2 is hinged on the extension column 11, and the center of gravity of the rotating frame 2 is lower than the extension column 11, so that the rotating frame 2 can realize self-correction through its own center of gravity, thereby improving the installation efficiency. At the same time, a lifting frame 21 is movable and arranged in the rotating frame 2 along the height direction of the rotating frame 2, and the switch cabinet body 3 and the lifting frame 21 are separately arranged, so that the traditional high-voltage switch cabinet is divided into two parts for transportation, which reduces the transportation difficulty. At the same time, after the switch cabinet body 3 is separated from the lifting frame 21, when the mounting frame 1 is installed, the total weight of the mounting frame 1 provided with the rotating frame 2 and the lifting frame 21 is lower than the total weight of the high-voltage switch cabinet as a whole, and it is more convenient to install the mounting frame 1 at a high place. At the same time, the lifting frame 21 arranged on the rotating frame 2 can automatically descend when the rotating frame 2 is at a high place, so that the staff can move the switch cabinet body 3 to the lifting frame 21 without hoisting the switch cabinet body 3.

[0024] Reference Figure 5 An arc groove 12 is provided on the mounting frame 1 around the extension column 11, and a rotating block 13 extending into the arc groove 12 is fixedly provided on the side wall of the rotating frame 2. The rotating block 13 slides with the arc groove 12 along the extension direction of the arc groove 12. A damper 14 is provided on one side of the arc groove 12. The rotating block 13 extends into the damper 14 along the extension direction of the arc groove 12 and slides with the damper 14.

[0025] After the installation of the mounting frame 1 is completed, the rotating frame 2 realizes automatic horizontal correction through its own center of gravity, that is, the rotating frame 2 is always in a vertical state, thereby ensuring that the upper end surface of the rotating frame 2 remains parallel to the horizontal plane, and the lower end surface of the lifting frame 21 arranged in the rotating frame 2 is also in a horizontal state. However, since the center of gravity of the rotating frame 2 will continuously correct the state of the rotating frame 2, if there is wind around the rotating frame 2, it will cause the rotating frame 2 to shake on the extension column 11. In order to reduce the external airflow pushing the rotating frame 2 to rotate when passing through the rotating frame 2, a damper 14 is provided on the mounting frame 1. At the same time, a rotating block 13 that can extend into the damper 14 and slidably cooperate with the damper 14 is provided on the rotating frame 2. The damper 14 has a bidirectional damping effect on the rotating block 13. Whether the rotating block 13 slides out of the damper 14 or slides into the damper 14, the damper 14 will have a damping effect on the rotating block 13, thereby reducing the shaking amplitude of the rotating frame 2 on the extension column 11.

[0026] Reference Figure 7: A thread is provided on the extension column 11, and a gear 22 which cooperates with the thread of the extension column 11 is provided on the outer peripheral rotating sleeve of the extension column 11. The gear 22 is located on the side of the rotating frame 2 away from the mounting frame 1, and a rubber ring 23 is provided between the gear 22 and the rotating frame 2. When the lifting frame 21 rises and enters the rotating frame 2, the gear 22 rotates on the extension column 11 and squeezes the rubber ring 23.

[0027] When the mounting frame 1 is just installed, the friction coefficient between the rotating frame 2 and the mounting frame 1 is small, and the rotating frame 2 can rotate normally. Then, the lifting frame 21 located in the rotating frame 2 begins to descend. When the upgrading frame descends, the gear 22 does not rotate. When the switch cabinet body 3 is placed on the lifting frame 21, the lifting frame 21 rises to the rotating frame 2. The rising lifting frame 21 drives the gear 22 to rotate. The gear 22 rotating on the extension column 11 gradually squeezes the rubber ring 23, so that the squeezing force between the mounting frame 1 and the rotating frame 2 gradually increases, thereby increasing the friction coefficient between the mounting frame 1 and the rotating frame 2 bracket, and avoiding the shaking of the rotating frame 2 when the lifting frame 21 drives the switch cabinet body 3 to rise to the rotating frame 2.

[0028] Reference Figure 7 A rack 211 is provided on the lifting frame 21 along its height direction and moves synchronously with the lifting frame 21. The rack 211 meshes with the gear 22 when the lifting frame 21 rises.

[0029] Reference Figure 7 The meshing teeth on the rack 211 are all arranged to face upwards at an angle. When the rack 211 descends with the lifting frame 21, the rack 211 and the gear 22 are slidably matched. When the rack 211 ascends with the lifting frame 21, the rack 211 and the gear 22 are meshed with each other.

[0030] Reference Figure 6 and Figure 7 A sliding groove 212 is horizontally opened on the lifting frame 21, and the rack 211 is slidably set in the sliding groove 212 along the extension direction of the sliding groove 212. A first spring 213 is set between the rack 211 and the bottom of the sliding groove 212 along the moving direction of the rack 211, and the two ends of the first spring 213 are fixedly connected to the sliding groove 212 and the rack 211 respectively.

[0031] By setting the gear 22 and the rack 211, and making the meshing teeth on the rack 211 tilted upward, when the rack 211 descends with the lifting frame 21, when the rack 211 passes one side of the gear 22, the rack 211 slides into the sliding groove 212 under the action of the gear 22, and the first spring 213 is squeezed. When the rack 211 completely passes the gear 22, the first spring 213 is restored. After the switch cabinet body 3 is placed in the lifting frame 21, when the lifting frame 21 drives the switch cabinet body 3 to rise, the rack 211 rises synchronously with the lifting frame 21, and the rising rack 211 and the gear 22 are meshed with each other and drive the gear 22 to rotate, so that the gear 22 presses the rubber ring 23, thereby increasing the friction coefficient of the mounting frame 1 and the rotating frame 2 during rotation, ensuring that after the lifting frame 21 drives the switch cabinet body 3 to completely rise to the rotating frame 2, the rotating frame 2 will not shake around the extension column 11.

[0032] Reference Figure 3 A screw rod 24 is rotatably arranged in the rotating frame 2 along the height direction of the rotating frame 2. The screw rod 24 passes through the lifting frame 21 and is threadedly matched with the lifting frame 21. A driving unit 25 for driving the screw rod 24 to rotate is arranged on the upper part of the screw rod 24.

[0033] Reference Figure 3 and Figure 4 The driving unit 25 includes a driving circuit 253 arranged above the rotating frame 2, in which a coolant is arranged. The driving circuit 253 is also provided with a vane pump 251 and a water pump 252 for driving the coolant to circulate in the driving circuit 253. The vane pump 251 is arranged on the upper part of the screw rod 24 and is used to drive the screw rod 24 to rotate.

[0034] Reference Figure 8-Figure 10 : A liquid inlet pipe 255 and a liquid outlet pipe 256 are vertically arranged on the upper part of the rotating frame 2, and a liquid inlet port and a liquid outlet port are arranged on the switch cabinet body 3. The liquid inlet pipe 255 and the liquid outlet pipe 256 are connected to the liquid inlet port and the liquid outlet respectively. Two reversing valves 254 are arranged on the driving circuit 253. The two reversing valves 254 are respectively located on both sides of the water pump 252 and are respectively connected to the liquid inlet pipe 255 and the liquid outlet pipe 256.

[0035] During the lifting process of the lifting frame, the liquid cooling pipeline and the drive unit in the high-voltage switch cabinet are in a non-connected state. Only after the lifting frame is fully raised, the drive unit can be connected to the liquid cooling pipeline, and the high-voltage switch cabinet is in a normal operating state at this time, thereby realizing the heat dissipation of the high-voltage switch cabinet during normal operation. The drive unit 25 set at the end of the screw rod 24 here can not only drive the screw rod to rotate, but also drive the hydraulic pipeline in the high-voltage switch cabinet after the high-voltage switch cabinet is installed. The switch valve adopts liquid cooling for heat dissipation. When it is necessary to drive the lifting frame 21 to descend, the water pump 252 is started, and the water pump 252 drives the coolant in the drive circuit 253 to flow. The flowing coolant drives the blades in the vane pump 251 to rotate, and then the vane pump 251 drives the screw rod 24 to rotate, so that the lifting frame 21 can descend smoothly. After the lifting frame 21 descends to the lowest position, the water pump 252 stops running. At this time, the switch cabinet body 3 is placed on the lifting frame 21, and the water pump 252 drives the coolant to flow in the reverse direction, so that the screw rod 24 rotates in the opposite direction, so that the lifting frame 21 can rise smoothly. When the lifting frame 21 is completely raised to the rotating frame 2, the liquid inlet and the liquid outlet on the upper part of the switch cabinet body 3 are connected to the liquid inlet pipe 255 and the liquid outlet pipe 256 respectively, and the two reversing valves 254 arranged on both sides of the water pump 252 are reversed synchronously. At this time, the water pump 252 is started again, and the water pump 252 pumps the coolant from the liquid inlet pipe 255 into the liquid inlet, and draws the coolant out from the liquid outlet pipe 256, so that the coolant in the switch cabinet body 3 circulates, thereby achieving cooling.

[0036] Reference Figure 1-Figure 10 The present invention also relates to a portable external intelligent high-voltage switch cabinet electric operation method, using a portable external intelligent high-voltage switch cabinet electric operation device, the specific steps are as follows: S1, the mounting frame 1 is fixedly set at the designated position, and the rotating frame 2 is self-corrected to a vertical state by its own low center of gravity; S2, the lifting frame 21 descends from the rotating frame 2. When the lifting frame 21 descends to the lowest position, the switch cabinet body 3 is placed on the lifting frame 21, and the lifting frame 21 drives the switch cabinet body 3 to rise into the rotating frame 2; S3. When the lifting frame 21 rises into the rotating frame 2, the rotating frame 2 and the extension column 11 disposed on the mounting frame 1 no longer rotate relative to each other.

[0037] Working principle: During use, the mounting frame 1 is first fixed at the specified position, and the rotating frame 2 is hinged on the extension column 11. Since the distance from the lower end of the rotating frame 2 to the extension column 11 is greater than the distance from the upper end of the rotating frame 2 to the extension column 11, the center of gravity of the rotating frame 2 rotatably set on the extension column 11 is located below the extension column 11. Therefore, when the mounting frame 1 is fixed to the specified position, there is no need to determine the horizontal state of the mounting frame 1, that is, when installing the mounting frame 1, there is no need to determine the horizontal state of the mounting frame 1 through a spirit level before installing it, even if the mounting frame 1 is tilted at a certain angle, the tilt at a certain angle means that the installer perceives the mounting frame 1 as being installed in a horizontal state through the naked eye, while the actual mounting frame 1 is tilted to a certain extent. After the mounting frame 1 is fixedly set at the designated position, the rotating frame 2 set on the extension column 11 rotates to a vertical state under the action of its own center of gravity. When the rotating frame 2 no longer rotates around the extension column 11, the lifting frame 21 set on the rotating frame 2 descends along the height direction of the rotating frame 2. When the lifting frame 21 descends to the lowest position, the switch cabinet body 3 is pushed into the lifting frame 21. After confirming that the switch cabinet has completely entered the lifting frame 21, the lifting frame 21 rises along the height direction of the rotating frame 2. When the lifting frame 21 completely enters the rotating frame 2, there is no relative rotation between the rotating frame 2 and the extension column 11. At this time, the installation of the high-voltage switch cabinet is completed. When the lifting frame 21 enters the rotating frame 2, the gear 22 rotates on the extension column 11 and squeezes the rubber ring 23, so that the friction coefficient between the rotating frame 2 and the mounting frame 1 continues to increase, and finally the rotating frame 2 and the extension column 11 no longer rotate, which can prevent the external wind from shaking the rotating frame 2 when it flows through the rotating frame 2, thereby ensuring that the switch cabinet body 3 set on the lifting frame 21 can work stably.

[0038] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
