Description

Technical Field

[0001] This utility model relates to the field of cathodic protection equipment technology, specifically a cathodic protection potential data acquisition device. Background Technology

[0002] Cathodic protection technology is a type of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes the cathode, thereby inhibiting electron migration that causes metal corrosion and avoiding or reducing corrosion. Cathodic protection data acquisition and recording instruments can effectively record the pipe-to-ground potential and AC voltage of buried pipeline cathodic protection, and are widely used in pipeline non-destructive testing companies, CNPC and Sinopec pipelines, gas companies, etc. in China.

[0003] A search revealed, for example, a Chinese utility model patent with publication number CN217351540U, which discloses a cathodic protection data logger. First, the logger body is rotated upward by rotating the shaft. Then, the bottom of the logger body is fixed into different slots by rotating the locking plate. This allows for easy adjustment of the logger body's angle, making it convenient for operators to use. Furthermore, the increased bottom space after the logger body is rotated allows for better heat dissipation through the fan, thus extending the lifespan of the logger body.

[0004] However, when adjusting the device, the recorder needs to be manually flipped up and the card plate inserted into the slot. The space between the recorder body and the protection box is small, making it inconvenient to manually align the card slot. Furthermore, the device is not easy to remove the recorder. Therefore, a cathodic protection potential data acquisition device is proposed to solve the above problems. Utility Model Content

It solves the problems of the comparative device being inconvenient to operate when adjusting the recorder angle and being unable to dehumidify the internal space of the protection box.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cathodic protection potential data acquisition device, including a protection box, a recorder body is installed inside the protection box, an adjustment mechanism is provided between the protection box and the recorder body, a box cover is hinged to the top of the protection box, and a heat dissipation and dehumidification mechanism is provided on the box cover;

A rotating shaft is rotatably connected to the top wall of the adjustment housing. A support plate is fixedly installed on the outside of the rotating shaft.

[0010] Furthermore, the heat dissipation and dehumidification mechanism includes a dehumidification housing, which is fixedly installed on the back of the box cover. A desiccant layer is installed inside the dehumidification housing, and a cooling fan is installed on the inner wall of the box cover.

[0011] Furthermore, the bottom of the support plate is fixedly connected to the second hinge block, and the top wall of the adjusting housing has a limit sliding hole.

[0012] Furthermore, the top wall of the support plate is provided with an installation groove, and limit springs are fixedly installed on the inner walls of both the left and right sides of the installation groove.

[0013] Furthermore, a limiting plate is fixedly installed on the side end of the limiting spring, and a baffle is fixedly installed on the top wall of the support plate.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] This cathodic protection potential data acquisition device features an adjustment mechanism. When the angle of the recorder body needs adjustment, simply control the motor to drive the threaded rod to rotate. As the threaded sleeve moves on the threaded rod, it drives the support rod to adjust its angle. The support rod then pushes the support plate to rotate, thus adjusting the angle of the recorder body. Furthermore, the device includes a limit plate and a baffle to clamp and limit the recorder body, preventing it from falling. The recorder body can also be freely placed and removed from the support plate, making it highly practical. Finally, a heat dissipation and dehumidification mechanism dries the airflow before it enters, keeping the inside of the protective box dry and dissipating heat from the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The cathode protection potential data acquisition device in this embodiment includes a protection box 1, a recorder body 2 is installed inside the protection box 1, an adjustment mechanism 3 is provided between the protection box 1 and the recorder body 2, a box cover 4 is hinged to the top of the protection box 1, and a heat dissipation and dehumidification mechanism 5 is provided on the box cover 4.

[0026] Specifically, the recorder body 2 measures key parameters of the cathodic protection system through sensors, such as on-state potential, off-state potential, AC voltage, natural corrosion potential, AC current, and DC current. After internal signal conversion and processing, the data is displayed on the screen on the recorder body 2 for easy reading by the user. This is existing technology and has been disclosed in application with announcement number CN217351540U.

[0027] Specifically, the adjustment mechanism 3 includes an adjustment housing 301. The adjustment housing 301 is installed on the inner bottom wall of the protective box 1. A motor 302 is fixedly installed on the inner side wall of the adjustment housing 301. A threaded rod 303 is fixedly installed at the output shaft of the motor 302. A threaded sleeve 304 is threadedly connected to the outside of the threaded rod 303. A first hinge block 305 is installed on the top of the threaded sleeve 304. A support rod 306 is hinged to the top of the first hinge block 305. The end of the support rod 306 away from the first hinge block 305 is hinged to... The second hinge block 307 is rotatably connected to the top wall of the adjusting housing 301 via a rotating shaft 308. A support plate 309 is fixedly installed on the outside of the rotating shaft 308. By setting the adjustment mechanism 3, when it is necessary to adjust the angle of the recorder body 2, it is only necessary to control the motor 302 to drive the threaded rod 303 to rotate. When the threaded sleeve 304 moves on the threaded rod 303, it will drive the angle of the support rod 306 to be adjusted. The support rod 306 then pushes the support plate 309 to rotate, so as to realize the angle adjustment of the recorder body 2.

[0028] Specifically, the heat dissipation and dehumidification mechanism 5 includes a dehumidification housing 501, which is fixedly installed on the back of the cover 4. A desiccant layer 502 is installed inside the dehumidification housing 501, and a cooling fan 503 is installed on the inner wall of the cover 4. By setting up the heat dissipation and dehumidification mechanism 5, the airflow is dried before air enters, so that the inside of the protective box 1 is kept dry and the equipment is cooled.

[0029] Specifically, the top wall of the dehumidification housing 501 has an air inlet, and a filter screen 10 is installed inside the air inlet. Air outlets are opened on both the left and right side walls of the protective box 1, and several ventilation holes are opened on the outer wall of the box cover 4. The interior of the dehumidification housing 501 is connected to the interior of the protective box 1 through the ventilation holes. The airflow enters the dehumidification housing 501 after being filtered by the filter screen 10 through the air inlet for dehumidification, and is then blown into the interior of the protective box 1 for heat dissipation.

[0030] Specifically, the top wall of the support plate 309 is provided with an installation groove 6. Limiting springs 7 are fixedly installed on the inner walls of both sides of the installation groove 6. Limiting plates 8 are fixedly installed on the side ends of the limiting springs 7. A baffle 9 is fixedly installed on the top wall of the support plate 309. Under the push of the limiting springs 7, the two limiting plates 8 clamp and fix the two sides of the equipment. At the same time, the baffle 9 blocks the bottom of the equipment to prevent the equipment from slipping.

[0031] When implementing this procedure, please follow these steps:

[0032] 1) First, place the recorder body 2 on the support plate 309, and clamp and fix the two limiting plates 8 on both sides of the recorder.

[0033] 2) Then control the motor 302 to drive the threaded sleeve 304 to move, thereby adjusting the angle of the support rod 306. The support rod 306 then pushes the support plate 309 to rotate, so as to realize the angle adjustment of the recorder body 2.

[0034] 3) Finally, turning on the cooling fan 503 can keep the inside of the protective box 1 dry and dissipate heat from the equipment.

[0035] In summary, by setting the adjustment mechanism 3, when the angle of the recorder body 2 needs to be adjusted, it is only necessary to control the motor 302 to drive the threaded rod 303 to rotate. When the threaded sleeve 304 moves on the threaded rod 303, it will drive the support rod 306 to adjust the angle. The support rod 306 will then push the support plate 309 to rotate, thereby realizing the angle adjustment of the recorder body 2. Furthermore, by setting the limiting plate 8 and the baffle 9, the recorder body 2 can be clamped and limited to prevent it from falling. At the same time, the recorder body 2 can be freely placed and removed on the support plate 309, which is highly practical. By setting the heat dissipation and dehumidification mechanism 5, the airflow is dried before air intake, keeping the inside of the protective box 1 dry and dissipating heat from the equipment.
