[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following is for reference. Figure 1 Description of an auxiliary device 100 for measuring the acid value of oleic acid in power plants according to an embodiment of the present invention.

[0020] like Figure 1 As shown, the auxiliary device 100 for measuring the oleic acid value of electricity according to an embodiment of the present invention includes: a conical flask 50, a reflux pipe 60, and a telescopic mechanism 10. The reflux pipe 60 is connected to and communicates with the conical flask 50. The telescopic mechanism 10 is configured to drive the conical flask 50 to reciprocate in the horizontal direction to shake the conical flask 50.

[0021] In this embodiment, a conical flask 50 and a reflux tube 60 are provided. The reflux tube 60 is connected to and communicates with the conical flask 50 to meet the experimental requirements for acid value determination. For example, during acid value determination, oil sample and alcohol can be quantitatively injected into the conical flask 50. The reflux tube 60 is sealed to the mouth of the conical flask 50. During water bath heating, the evaporated liquid can flow back into the conical flask 50 through the reflux tube 60, thereby keeping the solution volume consistent and meeting the requirements for acid value determination.

[0022] For example, in the acid value determination experiment, after the conical flask 50 and the reflux tube 60 are assembled and installed on the telescopic end of the telescopic mechanism 10, the operator can open the telescopic mechanism 10 through the control panel or other structures, so that the telescopic mechanism 10 drives the conical flask 50 and the reflux tube 60 to move back and forth in the horizontal direction, thereby shaking the conical flask 50. After shaking for five minutes, the telescopic mechanism 10 can stop moving, and the conical flask 50 can be removed from the telescopic mechanism 10 for the next operation.

[0023] In this embodiment, a telescopic mechanism 10 is provided to drive the conical flask 50 to move back and forth in the horizontal direction, thereby replacing manual shaking of the conical flask 50. During the water bath heating process, the telescopic mechanism 10 can stably shake the conical flask 50, making the shaking more stable. In multiple acid value determination experiments, the consistency and repeatability of shaking can be maintained, thus effectively avoiding human error caused by manual operation or intervention, and greatly improving the accuracy and repeatability of acid value determination.

[0024] In this embodiment, the telescopic mechanism 10 is set to simulate manual shaking of the conical flask 50, which can effectively realize the standardization and automation of acid value determination, reduce the labor intensity of acid value determination experiments, and keep the operator away from the water bath heating position, avoiding injury to the operator due to hot water splashing or solution splashing, thus making the acid value determination experiment operation simpler and safer.

[0025] According to the embodiment of the present invention, the auxiliary device 100 for determining the acid value of oil for power applications drives the conical flask 50 to move back and forth in the horizontal direction by setting a telescopic mechanism 10 to shake the conical flask 50. The structure is simple and can simulate manual shaking of the conical flask 50, replacing manual shaking, thereby effectively avoiding human error caused by manual operation and reducing labor intensity. It makes the shaking of the conical flask 50 more stable and can maintain the consistency of shaking in multiple tests, making the accuracy and repeatability of the acid value determination experiment better. It enables the acid value determination experiment to be standardized and automated, thus making the acid value determination experiment simpler and safer.

[0026] In some embodiments of this utility model, such as Figure 1 As shown, the telescopic mechanism 10 may include: a first driving member and a first telescopic rod 11. The telescopic end of the first telescopic rod 11 is connected to the conical bottle 50, and the first driving member is connected to the first telescopic rod 11 in a transmission connection.

[0027] In this embodiment, the telescopic mechanism 10 includes a first driving member and a first telescopic rod 11. The telescopic end of the first telescopic rod 11 is connected to the conical flask 50. The first driving member and the first telescopic rod 11 are connected by a transmission connection. The structure is simple and can well meet the usage requirements. During the acid value determination experiment, when the conical flask 50 needs to be shaken, the first driving member can drive the first telescopic rod 11 to rotate, so that the telescopic end of the first telescopic rod 11 can drive the conical flask 50 to move back and forth, thereby shaking the solution in the conical flask 50. For example, the first driving member and the first telescopic rod 11 as a whole can be an electric push rod structure, where the first driving member is the motor of the electric push rod and the first telescopic rod 11 is the push rod of the electric push rod. The first driving member and the first telescopic rod 11 as a whole can also be set as a hydraulic rod structure or a cylinder structure, etc., as long as the usage requirements are met.

[0028] In one embodiment of this utility model, such as Figure 1As shown, the first telescopic rod 11 is along the first direction (e.g.) Figure 1 Extending in the left and right directions shown, the auxiliary device 100 for measuring oleic acid value for electric power applications may also include a first clamping member 20, which is connected to the telescopic end of the first telescopic rod 11, and the conical bottle 50 is clamped in the first clamping member 20.

[0029] In this embodiment, the first telescopic rod 11 extends along the first direction, so the first telescopic rod 11 can drive the conical flask 50 to move back and forth along the first direction to achieve shaking. The electric oleic acid value measuring auxiliary device 100 is provided with a first clamping member 20. The first clamping member 20 is connected to the telescopic end of the first telescopic rod 11 and clamps the conical flask 50. The structure is simple and facilitates the assembly and fixation of the conical flask 50 and the first telescopic rod 11, so that the conical flask 50 can be easily picked up and put down. For example, when assembling the device, the first clamping member 20 can clamp and fix the conical flask 50 on the first telescopic rod 11 by clamping. After shaking is completed, the first clamping member 20 releases the conical flask 50, and the conical flask 50 can be removed from the first telescopic rod 11.

[0030] In some examples of this utility model, such as Figure 1 As shown, the auxiliary device 100 for measuring oleic acid value in electrical applications may further include a second clamping member 30, with the return pipe 60 clamped in the second clamping member 30. The second clamping member 30 and the first clamping member 20 are aligned vertically (e.g., in the vertical direction). Figure 1 The components are arranged at intervals in the vertical direction shown. The second clamping member 30 is connected to the telescopic end of the first telescopic rod 11. Alternatively, the telescopic mechanism 10 may also include a second driving member and a second telescopic rod 12, with the second clamping member 30 connected to the telescopic end of the second telescopic rod 12.

[0031] In this embodiment, a second clamping member 30 is provided to clamp the reflux pipe 60, which can make the reflux pipe 60 more stable during the overall movement with the conical bottle 50, and avoid tilting or other issues that could lead to connection failure or sealing failure with the conical bottle 50. This makes the overall movement of the conical bottle 50 and the reflux pipe 60 more stable and reliable, and also facilitates the picking and putting-away operation of the reflux pipe 60.

[0032] In this embodiment, the second clamping member 30 and the first clamping member 20 are arranged at intervals in the vertical direction. The arrangement is reasonable and can be well matched with the arrangement and assembly position of the conical bottle 50 and the reflux pipe 60 for clamping and fixing.

[0033] In this embodiment, the second clamping member 30 is connected to the telescopic end of the first telescopic rod 11. That is, the telescopic end of the first telescopic rod 11 is connected to the first clamping member 20 and the second clamping member 30. The first telescopic rod 11 can simultaneously drive the conical flask 50 and the reflux pipe 60 to reciprocate along the first direction via the first clamping member 20 and the second clamping member 30. This reasonable arrangement allows the first clamping member 20 and the second clamping member 30 to move synchronously while the first telescopic rod 11 drives the conical flask 50 to reciprocate, thus providing stable and reliable clamping and fixing. This allows the conical flask 50 and the reflux pipe 60 to move synchronously and stably as a whole via the first telescopic rod 11. For example, the first clamping member 20 and the second clamping member 30 can be installed and fixed to the telescopic end of the first telescopic rod 11 via a connecting frame or other structure.

[0034] In this embodiment, the telescopic mechanism 10 is further provided with a second driving member and a second telescopic rod 12. The second clamping member 30 is connected to the telescopic end of the second telescopic rod 12. The first clamping member 20 and the second clamping member 30 are driven by the first telescopic rod 11 and the second telescopic rod 12 respectively to move back and forth as a whole in the first direction. The structure is simple and easy to arrange. The first telescopic rod 11 and the second telescopic rod 12 can be synchronously moved back and forth by the synchronous control of the first driving member and the second driving member, so that the conical bottle 50 and the reflux pipe 60 can move back and forth stably as a whole. For example, the first telescopic rod 11 and the second telescopic rod 12 can be arranged at intervals in the vertical direction.

[0035] In some examples of this utility model, the height of the first clamping member 20 is adjustable, and / or the reciprocating movement distance of the first telescopic rod 11 is adjustable.

[0036] In this embodiment, the height of the first clamping member 20 is adjustable, which can meet the clamping and fixing needs of conical bottles 50 of different specifications and sizes. For example, when both the first clamping member 20 and the second clamping member 30 are connected to the telescopic end of the first telescopic rod 11, the first clamping member 20 and the second clamping member 30 can be installed on the telescopic end through a connecting frame structure. The first clamping member 20 and the connecting frame structure can slide together through a slide rail and slide groove structure and be positioned and locked by locking members, etc., so that the position of the first clamping member 20 in the vertical direction is adjustable, thereby adjusting its height. The second clamping member 30 can also be configured with a slide groove and slide rail structure, etc., as needed. Alternatively, the first clamping member 20 and the second clamping member 30 can be fixedly connected to the telescopic end of the first telescopic rod 11 through a connecting frame structure. The height of the first clamping member 20 and the second clamping member 30 can be adjusted as a whole by moving the first telescopic rod 11 in the vertical direction, etc., as long as the height adjustment needs of the first clamping member 20 are met.

[0037] In this embodiment, the reciprocating distance of the first telescopic rod 11 is adjustable. The distance of reciprocating movement can be adjusted according to the shaking requirements to change the shaking amplitude, thus meeting the shaking needs of acid value determination experiments with different capacities. For example, the telescopic mechanism 10 can be an adjustable electric push rod to meet the need for adjustable reciprocating distance.

[0038] In this embodiment, the height of the first clamping member 20 is adjustable, and the reciprocating movement distance of the first telescopic rod 11 is adjustable, so that the auxiliary device 100 for measuring the oleic acid value of electricity can be flexibly adjusted according to the specific size and specifications of the conical flask 50 and the shaking requirements, thus improving its adaptability.

[0039] In some embodiments of this utility model, such as Figure 1 As shown, the auxiliary device 100 for measuring oleic acid value for power applications may also include a fixed bracket 40, and the telescopic mechanism 10 is detachably connected to the fixed bracket 40.

[0040] In this embodiment, a fixed bracket 40 is provided, and the telescopic mechanism 10 is detachably connected to the fixed bracket 40. The structure is simple, which facilitates the installation, fixing and position adjustment of the telescopic mechanism 10. It can facilitate the height adjustment of the first telescopic rod 11. The fixed bracket 40 can provide stable support for the telescopic mechanism 10, so that the conical bottle 50 and the return pipe 60 can be shaken stably.

[0041] In some embodiments of this utility model, such as Figure 1 As shown, the auxiliary device 100 for measuring oleic acid value for power applications also includes a control module 80, which is electrically connected to the telescopic mechanism 10.

[0042] In this embodiment, the control module 80 is electrically connected to the telescopic mechanism 10 to meet the control requirements of the telescopic mechanism 10. For example, the control module 80 can accurately control parameters such as the running time, reciprocating frequency and stroke of the telescopic mechanism 10, thereby achieving automation and standardization in the shaking process and further improving the ease of operation of the acid value determination experiment as well as the accuracy and repeatability of the acid value determination.

[0043] In one embodiment of this utility model, the control module 80 may include: a start switch, a timing unit, and an adjustment unit. The start switch is used to control the opening of the telescopic mechanism 10, the timing unit is used to control the shaking time of the conical flask 50, and the adjustment unit is used to adjust the shaking speed and shaking time of the telescopic mechanism 10 on the conical flask 50.

[0044] In this embodiment, the control module 80 includes a start switch, a timing unit, and a control unit. During the acid value determination experiment, the operator can conveniently start the telescopic mechanism 10 through the start switch, control the shaking time through the timing unit according to the shaking needs, and control the shaking speed and time through the control unit, thereby effectively and flexibly controlling the shaking, thus improving the convenience of operation, ensuring that the auxiliary device for determining the acid value of electricity can maintain consistency in multiple tests, and making the determination results more reliable.

[0045] In some examples of this utility model, such as Figure 1 As shown, the auxiliary device 100 for determining the oleic acid value of an electric power source may further include a water bath heating tank 70, which is used for water bath heating of the conical flask 50. The water bath heating tank 70 is equipped with a heating element, which is electrically connected to a control unit to adjust the water bath temperature of the water bath heating tank 70. The heating element is also electrically connected to a timing unit to control the heating time of the heating element.

[0046] In this embodiment, a water bath heating tank 70 is set to heat the conical flask 50 in a water bath to meet the experimental requirements for acid value determination. The water bath heating tank 70 is equipped with a heating element, which is electrically connected to a control unit. This allows the control unit to control the heating element to regulate the water bath temperature during water bath heating. For example, the water bath heating tank 70 can be equipped with a temperature sensor electrically connected to the control unit to provide feedback on the water bath temperature. The heating element is electrically connected to a timing unit, allowing the timing unit to control the heating of the heating element at a set time. This allows the shaking operation of the conical flask 50 and the water bath heating of the conical flask 50 by the water bath heating tank 70 to be coordinated and controlled by the control module 80, further improving the automation level and stability of the experimental conditions in the acid value determination process. This, in turn, can improve the accuracy and repeatability of the acid value determination results to a certain extent.

[0047] In one example of this utility model, the control module 80 may further include a status display unit, which is used to display the heating temperature of the water bath and the shaking time of the conical flask 50.

[0048] In this embodiment, the control module 80 is equipped with a status display unit to display the heating temperature and shaking time. The structure is simple and makes it easy for operators to intuitively monitor the experimental process and status, and to understand the operation of heating and shaking so as to facilitate subsequent operations for acid value determination.

[0049] The following will refer to Figure 1 This invention describes an auxiliary device 100 for measuring the acid value of oleic acid in electrical applications, according to a specific embodiment of the present invention.

[0050] like Figure 1As shown, the auxiliary device 100 for determining the oleic acid value of electrical components includes a fixed bracket 40, a telescopic mechanism 10, a conical flask 50, a water bath heating tank 70, a reflux pipe 60, a first clamping member 20, a second clamping member 30, and a control module 80. The telescopic mechanism 10 is detachably mounted on the fixed bracket 40 and includes a first driving member, a first telescopic rod 11, a second driving member, and a second telescopic rod 12. The first driving member is drivenly connected to the first telescopic rod 11, and the second driving member is drivenly connected to the second telescopic rod 12. Both the first telescopic rod 11 and the second telescopic rod 12 extend along a first direction and are spaced apart in the vertical direction. Below the first telescopic rod 11... A water bath heating tank 70 is provided, which is equipped with a heating element. A control module 80 is located on the side wall of the water bath heating tank 70. The telescopic end of the first telescopic rod 11 is provided with a first clamping member 20, which is a claw, and clamps the mouth of the conical flask 50. The reflux pipe 60 is installed at the mouth of the conical flask 50. The telescopic end of the second telescopic rod 12 is provided with a second clamping member 30, which is a claw and clamps the reflux pipe 60. The control module 80 is electrically connected to the telescopic mechanism 10. The control module 80 includes a start switch, a timing unit, a control unit, and a status display unit, which is a display screen.

[0051] During the acid value determination experiment, after the conical flask 50 is filled with solvent and sample, it is fixed to the first clamp 20, and the reflux tube 60 is fixed to the second clamp 30. The control module 80 sets the shaking time to 5 minutes and the water bath temperature to 85℃. When the start switch is turned on, the telescopic mechanism 10 drives the conical flask 50 and the reflux tube 60 to reciprocate as a whole, simulating manual shaking. After the end, the telescopic mechanism 10 automatically stops, and the heating element stops heating synchronously. The operator takes out the sample for subsequent titration. The whole process can achieve standardized and automated operation, effectively reduce human error, and significantly improve the accuracy and repeatability of acid value determination results.

[0052] The auxiliary device 100 for determining the acid value of oil for power applications in this embodiment uses a telescopic mechanism 10 to drive the conical flask 50 to move back and forth in the horizontal direction to shake the conical flask 50. The structure is simple and can simulate manual shaking of the conical flask 50, replacing manual shaking. This effectively avoids human error caused by manual operation and reduces labor intensity. It makes the shaking of the conical flask 50 more stable and can maintain the consistency of shaking in multiple tests, thus improving the accuracy and repeatability of the acid value determination experiment. It also enables the acid value determination experiment to be standardized and automated, making the acid value determination experiment simpler and safer.
