Due to the increase in the capacity of a single machine, the capacitance of the generator set winding to the ground is bound to increase. In order to meet the needs of large-capacity electrical equipment testing, the resonance principle is adopted to match the capacitance of the tested equipment to the ground with an adjustable reactor or an adjustable excitation reactance to form resonance; and the power tuner is a device used to adjust and stabilize the voltage and frequency in the power system. It is usually used in the power system, especially when connected to different power grids or power sources, to ensure the stable operation of the power system.

[0003] In actual use, the power system will face constantly changing load demands and power network conditions, and traditional tuner bodies are mostly installed on equipment through brackets. After installation, they cannot be quickly changed in position for a second time, and the bracket can only be disassembled and assembled as a whole to change the position. This method is overall cumbersome. At the same time, the needs of the power system will also face the need for tuners of different types or specifications. If the installed tuner cannot change its position, it cannot meet new needs and the tuner needs to be reinstalled or replaced. Therefore, a tuning device is proposed to solve the above problems.

[0023] Example

[0024] Depend on Figure 1-4 Provided is a tuning device, comprising a position adjustment component 1, a clamping component 2 and a tuner body 3;

[0025] The clamping assembly 2 is assembled on the position adjustment assembly 1, and the tuner body 3 is detachably assembled on the clamping assembly 2;

[0026] The position adjustment assembly 1 includes a screw seat 11, which is U-shaped as a whole and has a screw rod 13 rotatably arranged therein, and a slider seat 14 is engaged with the outside of the screw rod 13, and the clamping assembly 2 is carried on the slider seat 14;

[0027] The clamping assembly 2 includes a main seat 21 arranged on the slider seat 14, and two positive and negative thread shafts 22 are rotatably provided on the main seat 21. Two bearing seats 23 are meshed on the two positive and negative thread shafts 22, and the two bearing seats 23 are respectively meshed with one of the dental floss of the positive and negative thread shafts 22; ear plates 24 are protruding from the two bearing seats 23, and the two ear plates 24 are arranged opposite to each other.

[0028] In this embodiment, through two oppositely movable ear plates 24, the provided clamping assembly 2 can quickly and conveniently install tuner bodies 3 of different sizes without the need for tedious adjustment and disassembly processes; thereby saving the time required for replacing the tuner body 3 and improving work efficiency, and at the same time can provide stable opposite clamping to ensure stable installation of the tuner body 3.

[0029] Furthermore, by means of the mutual movement and coordination of the multiple components within the position adjustment assembly 1, the slider seat 14 can be moved linearly within the travel range of the screw seat 11, and then the position adjustment of the slider seat 14 can be used to realize the rapid installation position adjustment of the tuner body 3. By cooperating with the disassembly and assembly of the tuner body 3 by the clamping assembly 2, the position of tuner bodies 3 of different sizes can be quickly adjusted. At the same time, by controlling the rotation of the screw 13, the position adjustment assembly 1 can accurately position the tuner body 3 to meet specific installation position requirements.

[0030] Specifically, refer to Figure 3-4The sides of the ear plates 24 are provided with anti-skid patterns, and the tuner body 3 is clamped between the two ear plates 24 and supported on the supporting seat 23 .

[0031] In this embodiment, in actual use, when the tuner body 3 is installed and carried on the two supporting seats 23, the user controls the rotation of the two positive and negative thread shafts 22, and makes the two supporting seats 23 engaged with the outside of the positive and negative thread shafts 22 move in opposite directions until the two ear plates 24 clamp and install the tuner body 3. In a preferred embodiment, the anti-slip grooves arranged on the side of the ear plate 24 can increase the friction between the ear plate 24 and the tuner body 3, thereby providing a firmer clamping force to prevent the tuner body 3 from sliding or shifting. At the same time, in a more preferred use, after the tuner body 3 is clamped between the two ear plates 24, the user can also use positioning bolts to further install and fix the tuner body 3 and the supporting seat 23.

[0032] Specifically, refer to Figure 3-4 A gear shaft 26 and two gear shafts 27 are rotatably mounted on one side of the main seat 21. The gear shaft 26 and the two gear shafts 27 are arranged in a triangular shape and a connecting toothed belt 28 is tensioned on the outside.

[0033] In this embodiment, in actual use, when the user drives the gear shaft 26 to rotate, the gear shaft 26 and the two gear shafts 27 are tensioned by connecting the toothed belt 28, so that the two gear shafts 27 distributed in a triangular shape can rotate synchronously with the gear shaft 26.

[0034] Specifically, refer to Figure 3-4 A reciprocating motor 25 is mounted on one side outer wall of the main seat 21 , and an output end of the reciprocating motor 25 passes through the main seat 21 and extends into the gear shaft 26 and is rotationally connected to the gear shaft 26 .

[0035] In this embodiment, the user connects the reciprocating motor 25 to a power source. When the output end of the reciprocating motor 25 rotates, the gear shaft 26 connected to the output end thereof can rotate accordingly.

[0036] Furthermore, when the gear shaft 26 is rotating, the two gear shafts 27 can rotate accordingly through the tension connection of the toothed belt 28. In a preferred embodiment, the two gear shafts 27 are respectively connected to one of the positive and negative thread shafts 22. At this time, the connection between the gear shaft 27 and the two positive and negative thread shafts 22 allows the positive and negative thread shafts 22 to keep rotating and be limited by the meshing of the same thread on the two positive and negative thread shafts 22. When the two gear shafts 27 are in forward rotation, the two positive and negative thread shafts 22 keep rotating clockwise, thereby causing the two bearing seats 23 meshed on the two positive and negative thread shafts 22 to perform opposite clamping movements and the distance between them is reduced. Similarly, when the two gear shafts 27 are in reverse rotation, the two positive and negative thread shafts 22 keep rotating counterclockwise. At this time, the two bearing seats 23 will keep moving in reverse and the distance between them will increase. The user can control the distance between the two bearing seats 23 to achieve clamping of tuner bodies 3 of different sizes.

[0037] Specifically, refer to Figure 1-2 The position adjustment assembly 1 further includes two bearing sleeves 12 disposed on the screw seat 11 , and both ends of the screw rod 13 are rotatably connected to the bearing sleeves 12 respectively.

[0038] In this embodiment, in actual use, after the tuner body 3 is assembled on the clamping assembly 2, the weight of the tuner body 3 will cause downward pressure on the clamping assembly 2, and the two screw rods 13 will be affected by the pressure and difficult to rotate. At this time, through the rotation cooperation between the bearing sleeve 12 and the screw rod 13, the rotation of the set bearing sleeve 12 can be more stable. The bearing sleeve 12 can share the load on the screw rod 13, reduce the direct contact of the screw rod 13 with force, help reduce the wear and fatigue of the screw rod 13, extend the service life of the screw rod 13, and ensure stable rotation.

[0039] Specifically, refer to Figure 1-2 Two side rods 15 are arranged between the screw seats 11. The two side rods 15 are respectively arranged on one side of the slider seat 14 and both penetrate the slider seat 14. A forward and reverse motor 16 is assembled on one side of the screw seat 11. The output end of the forward and reverse motor 16 penetrates the screw seat 11 and is connected to the screw 13.

[0040] In this embodiment, in actual use, when the user connects the power supply to the forward and reverse motor 16, the rotation of the output end of the forward and reverse motor 16 is controlled, so that the set screw rod 13 can rotate accordingly, and at the same time is limited by the two side rods 15. At this time, the slider seat 14 engaged with the outside of the screw rod 13 can move in a straight line along the travel range of the screw rod 13. The user can realize the left and right lateral movement of the slider seat 14 by controlling the steering of the screw rod 13.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
