The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1, reference Figures 1 to 9 , which is the first embodiment of the present invention, provides a heating device for an insulating oil micro-water meter, the device comprising a basic component 100, including a basic component 101, a supporting component 102 arranged on the basic component 101, and a heating component 103 arranged on the supporting component 102.

[0032] Among them, the basic component 101 is used to detect the insulating oil to obtain the moisture content inside the insulating oil, the supporting component 102 is used to support the insulating oil container 101c so that the instrument can operate normally, and the heating component 103 is set to heat the internal insulating oil so that the insulating oil is at a suitable temperature during detection.

[0033] Preferably, the insulating oil is heated by the heating component 103 so that the temperature of the insulating oil body is always around 30°, and then detected by the basic component 101 to ensure the accuracy of the data.

[0034] Furthermore, the limiting component 200 includes a moving component 201 disposed on the base component 101 , a sliding component 202 disposed on the moving component 201 , and a control component 203 disposed on the base component 101 .

[0035] Among them, the setting of the moving component 201 is used to facilitate the movement of the supporting component 102, the control component 203 is used to control the expansion and contraction of the long rod 202b, and the setting of the sliding component 202 is used to control the long rod 202b so that it can achieve expansion and contraction.

[0036] Preferably, the supporting component 102 is driven to move by the moving component 201, and the control component 203 is driven to operate at the same time, so that the control component 203 restricts the insulating oil container 101c with the cooperation of the sliding component 202 to prevent it from moving, causing the solution inside to shake.

[0037] Furthermore, the power transmission component 300 includes a rotating component 301 disposed on the base component 101 , a power transmission component 302 disposed inside the rotating component 301 , and a contraction component 303 disposed on the power transmission component 302 .

[0038] Among them, the rotating component 301 is used to control the rotation of the power transmission component 302, so as to complete the connection and separation of the electrode 302b and the conductor 302d. The power transmission component 302 is set to provide electrical energy to the heating component 103, and the contraction component 303 is set to facilitate the recovery of the conductor 302d in the power transmission component 302 to the inside.

[0039] Preferably, when the support assembly 102 moves downward, the rotating assembly 301 is driven to move downward, so that the rotating assembly 301 controls the connection between the electrode 302b and the conductor 302d inside the power transmission assembly 302, thereby realizing the transmission of the electrode 302b of the heating module. After taking out the container of insulating oil, the support plate 102b rises, and the rotating assembly 301 controls the power transmission assembly 302 to connect and disconnect, thereby completing power off.

[0040] In summary: by moving the support component 102 downward, the moving component 201 drives the control component 203 to operate, and the control component 203 operates in cooperation with the sliding component 202, so that the heating component 103 clamps the insulating oil container 101c body to prevent it from moving. At the same time, when the support component 102 moves downward, it will drive the rotating component 301 to move, so that the rotating component 301 operates, so that the electrode 302b and the conductor 302d inside the power transmission component 302 are connected, and the electrode 302b of the heating module is transported. After taking out the container of insulating oil, the support plate 102b rises, and the rotating component 301 controls the power transmission component 302 to connect and disconnect, and complete the power off.

[0041] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention, comprising: a basic component 101 comprising a micro-water meter body 101a, an electrode 302b connecting wire 101b arranged on the micro-water meter body 101a, and an insulating oil container 101c arranged on the micro-water meter body 101a.

[0043] Furthermore, the support assembly 102 includes a placement groove 102a disposed on the micro-water meter body 101a, and a support plate 102b disposed inside the placement groove 102a.

[0046] The movable groove 201a is used to limit the moving track of the movable block 201c, and the connecting groove 201b is used to facilitate the movement of the L-shaped rod 201d inside.

[0047] Preferably, when the container filled with insulating oil is placed on the support plate 102b, the weight of its body will press the support plate 102b downward, and then move downward through the L-shaped plate, so that the movable plate moves with it, and the control component 203 is driven to operate by controlling the movement of the movable plate.

[0048] Furthermore, the sliding assembly 202 includes a through hole 202a disposed on the moving block 201c, a long rod 202b disposed inside the through hole 202a, a sliding groove 202c disposed on the long rod 202b, and a sliding block 202d disposed inside the through hole 202a.

[0049] The through hole 202a is provided to facilitate the movement of the long rod 202b inside the moving block 201c, and the sliding groove 202c is provided to cooperate with the slider 202d, thereby limiting the long rod 202b so that it can only expand and contract.

[0050] Furthermore, the control assembly 203 includes a cavity 203a disposed outside the moving groove 201a, an inclined groove 203b disposed inside the cavity 203a, and a control rod 203c disposed inside the inclined groove 203b.

[0051] The cavity 203a is provided to facilitate the movement of the long rod 202b, and the inclined groove 203b is provided to limit the movement trajectory of the control rod 203c, so that when the long rod 202b moves downward, the control rod 203c will cooperate with the inclined groove 203b to drive the long rod 202b to expand and contract.

[0052] Preferably, when the support plate 102b moves downward, the L-shaped rod 201d drives the moving block 201c to move downward. During the downward movement of the moving block 201c, the control rod 203c moves downward with it, so that the inclined groove 203b drives the control rod 203c to move toward the middle, thereby allowing the long rod 202b to expand and contract.

[0053] In summary: by placing the insulating oil container 101c filled with the solution on the support plate 102b inside the placement groove 102a, the insulating oil container 101c will press the support plate 102b downward, so that the support plate 102b drives the moving block 201c to move downward through the L-shaped rod 201d, so that the long rod 202b moves with it, and when the long rod 202b moves downward, the control rod 203c will move inside the inclined groove 203b, so that the arc plate 103a is controlled by the long rod 202b to move toward the middle to clamp the insulating oil container 101c, thereby preventing the insulating oil container 101c body from moving.

[0054] Example 3, reference Figure 2 to Figure 9 , which is the third embodiment of the present invention, comprises: the heating assembly 103 comprises an arc plate 103a arranged inside the accommodating groove 102a, a heating ring 103b arranged on the arc plate 103a, and a temperature sensor 103c arranged on the arc plate 103a.

[0055] Among them, the arc plate 103a is used to clamp the insulating oil container 101c, so that the heating ring 103b is close to the insulating oil container 101c, and the insulating oil inside is heated so that the insulating oil is at about 30 degrees before detection, which is convenient for instrument detection. The temperature sensor 103c is used to detect the temperature to prevent the temperature from being too high or too low.

[0056] Preferably, by cooperating with the inclined groove 203b and the control rod 203c in the control assembly 203, the arc plate 103a is closely attached to the outer wall of the insulating oil container, so that the heating coil 103b can control the temperature of the insulating oil inside.

[0057] Furthermore, the rotating assembly 301 includes a rotating ring 301a disposed at the bottom end of the supporting plate 102b, a limiting point 301b disposed outside the rotating ring 301a, and an arc groove 301c disposed inside the accommodating groove 102a.

[0058] The rotating ring 301a is used to place the electrode 302b, so as to facilitate the connection between the conductor 302d in the power transmission component 302 and the electrode 302b to supply power to the heating component 103, and the limiting point 301b is used to cooperate with the arc groove 301c to control the rotation of the rotating ring 301a.

[0059] Preferably, when the support plate 102 b moves downward, the rotating ring 301 a will rotate along with it, so that the power transmission component 302 on the rotating ring 301 a is connected to provide electrical energy for the heating component 103 .

[0060] Furthermore, the power transmission component 302 includes a long groove 302a disposed inside the rotating ring 301a, an electrode 302b disposed inside the long groove 302a, a connection plate 302c disposed at the bottom end of the support plate 102b, and a conductor 302d disposed on the connection plate 302c.

[0061] The long groove 302a is used to place the electrode 302b, so that the rotating ring 301a can drive the electrode 302b to rotate together when rotating, and the connecting plate 302c is used to facilitate the rotating ring 301a to rotate thereon.

[0062] Preferably, the limiting point 301b on the rotating ring 301a moves inside the arc groove 301c by moving the support plate 102b downward, so that the rotating ring 301a rotates while the support plate 102b moves downward, thereby connecting the conductor 302d on the connecting disk 302c and the electrode 302b on the rotating ring 301a to form a passage, thereby providing electrical energy to the heating module.

[0063] Furthermore, the contraction assembly 303 includes a sliding groove 303a disposed on the connecting disk 302c, a moving disk 303b disposed inside the sliding groove 303a, and a contraction spring 303c disposed on the moving disk 303b.

[0065] In summary, by placing the insulating oil container 101c filled with the solution on the support plate 102b inside the placement groove 102a, the insulating oil container 101c will press the support plate 102b downward, so that the support plate 102b drives the moving block 201c to move downward through the L-shaped rod 201d, so that the long rod 202b moves with it, and when the long rod 202b moves downward, the control rod 203c will move inside the inclined groove 203b, so that the arc plate 103a is controlled by the long rod 202b to move toward the middle to clamp the insulating oil container 101c. Insulating oil container 101c is prevented from moving; in addition, when supporting plate 102b moves downward, arc groove 301c cooperates with limiting point 301b to drive rotating ring 301a to rotate, so that conductor 302d inside connecting disk 302c is connected with electrode 302b on arc plate 103a, so that heating plate on arc plate 103a heats insulating oil inside insulating oil container 101c, thereby ensuring that insulating oil is at suitable temperature during detection, and ensuring accuracy of detected data.
