Description

Technical Field

[0001] This utility model relates to the technical field of potentiostats, and in particular to an intelligent anti-interference potentiostat. Background Technology

[0002] A potentiostat is a core device in electrochemical protection systems. Its main function is to maintain the potential of the protected metal structure (such as buried pipelines, storage tanks, and offshore platforms) at a set constant value by adjusting the output current, thereby inhibiting metal corrosion. It is a key device in impressed current cathodic protection technology and achieves automatic control through a closed-loop feedback system.

[0003] In current potentiostat installations, if power lines and signal lines are installed parallel to each other, electromagnetic coupling interference from the power lines to the signal lines can easily occur. Because the power lines contain alternating current, they generate an alternating magnetic field. Since the signal lines are within this magnetic field, an interfering electromotive force will be induced in the signal lines according to the principle of electromagnetic induction. This interference will be superimposed on the original effective signal transmitted by the signal lines, causing signal distortion. As a result, the signal quality received and processed by the potentiostat is significantly reduced, negatively impacting its key performance indicators such as potential control accuracy and stability, thus diminishing the potentiostat's effectiveness. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent anti-interference potentiostat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An intelligent anti-interference potentiostat includes a base with two grooves machined on its surface. The inner walls of the two grooves are fixedly connected to one end of two springs, and the other ends of the two springs are fixedly connected to corresponding abutment blocks. The outer walls of the two abutment blocks are slidably connected to the corresponding grooves. The upper ends of the two abutment blocks are fixedly connected to two handles, and the outer walls of the two abutment blocks are fixedly connected to two protrusions. The two abutment blocks abut against corresponding turntables, and the upper ends of the two turntables are fixedly connected to two cable organizers. The outer walls of both turntables are rotatably connected to the base.

[0007] Preferably, a metal shell is installed on the upper end of the base, a through hole is opened at the rear end of the metal shell, and the potentiostat body is placed inside the metal shell.

[0008] Preferably, the lower ends of the two turntables are fixedly connected to the corresponding discs, and the outer walls of the two discs are fixedly connected to the two stop bars.

[0009] Preferably, the lower end of the base is fixedly connected to four supports, and the four supports are respectively arranged at the four corners of the base.

[0010] Preferably, a display screen is mounted on the surface of the potentiostat body, and the outer wall of the potentiostat body is fixedly connected to the wire connection end.

[0011] Preferably, the metal casing is made of aluminum alloy.

[0012] Preferably, a circular groove is installed in the middle of the turntable, the size of which matches the size of the protrusion, and the circular groove is in contact with the protrusion.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. With the base, slide, spring, clamping block, handle, protrusion, turntable, and cable organizer, when the operator places the power cord and signal line on the two cable organizers respectively, the operator pulls one handle. The handle moves the clamping block, which in turn moves the spring to press it down. After the clamping block is no longer pressing against the turntable, the operator rotates the turntable, which causes the signal line above to rotate, preventing the signal line from being placed parallel to the power cord. Then, the operator releases the handle, and the spring returns to its original position, causing the clamping block to press against the turntable, thus avoiding electromagnetic coupling interference. This improves the working effect of the potentiostat.

[0015] 2. The metal casing isolates the internal circuitry of the instrument from the external electromagnetic environment, preventing interference with the operation of the potentiostat and thus improving its performance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An intelligent anti-interference potentiostat includes a base 4. Two grooves 6 are machined on the surface of the base 4. The inner walls of the two grooves 6 are fixedly connected to one end of two springs 7, which enable a retaining block 8 to always press against a turntable 11. The other ends of the two springs 7 are fixedly connected to corresponding retaining blocks 8. The outer walls of the two retaining blocks 8 are slidably connected to the corresponding grooves 6, allowing the retaining blocks 8 to move on the grooves 6. The upper ends of the two retaining blocks 8 are fixedly connected to two handles 9, which facilitate the operator's movement of the retaining blocks 8. The outer walls of the two retaining blocks 8 are fixedly connected to two protrusions 10, which cause the retaining blocks 8 to move. The two retaining blocks 8 press against corresponding turntables 11. The upper ends of the two turntables 11 are fixedly connected to two cable organizers 13, which can adjust the angle of the wires. The outer walls of both turntables 11 are rotatably connected to the base 4, allowing the turntables 11 to rotate on the base 4. When the operator places the power cord and signal line on the two cable organizers 13 respectively, the operator pulls a handle 9, which moves the clamping block 8. The clamping block 8 then presses the spring 7. After the clamping block 8 is no longer pressing against the turntable 11, the operator rotates the turntable 11. The turntable 11 rotates the signal line above it, preventing the signal line from being placed parallel to the power cord. Then, the operator releases the handle 9, and the spring 7 returns to its original position, causing the clamping block 8 to press against the turntable 11, thus avoiding electromagnetic coupling interference. This improves the working effect of the potentiostat.

[0024] In this embodiment, a metal casing 16 is installed on the upper end of the base 4. The metal casing 16 can isolate the internal circuitry of the instrument from the electromagnetic environment, preventing interference with the operation of the potentiostat body 1. A through hole 17 is provided at the rear end of the metal casing 16 to facilitate the entry of the power cord into the metal casing 16. The potentiostat body 1 is placed inside the metal casing 16. The lower ends of the two turntables 11 are fixedly connected to the corresponding discs 14. The turntables 11 drive the discs 14 to rotate. The outer walls of the two discs 14 are fixedly connected to two stop rods 15. The discs 14 drive the stop rods 15 to rotate. The stop rods 15 prevent the angles of the two discs 14 from being the same, preventing the cable organizer 13 from causing the power cord and signal line to be placed parallel. The lower end of the base 4... The end is fixedly connected to four brackets 5, which are respectively set at the four corners of the base 4. A display screen 2 is installed on the surface of the potentiostat body 1. The display screen 2 allows the operator to know the working status of the potentiostat body 1. The outer wall of the potentiostat body 1 is fixedly connected to the wire connection end 3. The metal shell 16 is made of aluminum alloy. The aluminum alloy material can isolate the internal circuit of the potentiostat body 1 from the external electromagnetic environment, thereby avoiding interference to the operation of the potentiostat body 1. A circular groove 12 is installed in the middle of the turntable 11. The size of the circular groove 12 matches the size of the protrusion 10. The circular groove 12 contacts the protrusion 10, and the protrusion 10 can be inserted into the circular groove 12 to fix the angle of the turntable 11.

[0025] The working principle of this embodiment is as follows: In use, the operator first places the power cord and signal line on two cable organizers 13 respectively, connecting both to the wire connection terminals 3 on the surface of the potentiostat body 1. Then, the operator pulls a handle 9, which moves a retaining block 8. The retaining block 8 then presses against a spring 7. After the retaining block 8 is no longer pressing against the turntable 11, the operator rotates the turntable 11, causing the signal line above it to rotate, preventing the signal line from being parallel to the power cord. After releasing the handle 9, the spring 7 returns to its original position, causing the retaining block 8 to press against the turntable 11, ensuring the angles of the two cable organizers 13 are not identical. Furthermore, the stop lever 15 ensures that the angles of the two turntables 11 will never be identical, thus avoiding electromagnetic coupling interference. Since the potentiostat body 1 is housed within an aluminum alloy metal casing 16, the casing isolates the internal circuitry of the potentiostat body 1 from the electromagnetic environment, preventing interference with its operation.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
