Description

Technical Field

[0001] The utility model relates to the technical field of pipeline drainage detection, and more specifically, to a pipeline drainage effect detection device. Background Art

[0002] Nowadays, due to the electromagnetic interference of subway stray currents, high-voltage transmission lines and high-speed trains, there are a large number of stray currents on the pipelines. The anode area interfered by the stray currents will cause corrosion to the pipelines, posing a safety hazard. Therefore, drainage equipment will be installed at locations where pipeline corrosion is severe to divert the stray currents and reduce corrosion to the pipelines.

[0003] Although drainage equipment is installed on the pipeline, the detection of the anti-corrosion effect of the drainage equipment is usually completed at one time by professional equipment and professional companies. Traditional daily inspections generally use digital multimeters for detection. The most commonly used digital multimeter for measuring stray current interference pipelines is large in size, does not have the function of storing and analyzing data, and is not easy for staff to carry, which brings inconvenience to the staff. Once the detection device is placed on site for a long time, it is easy for moisture to enter the device, which can easily cause damage to the internal electrical components. Therefore, the use of ordinary digital multimeters can no longer meet the needs of the site. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art that a digital multimeter cannot record data, is inconvenient to carry and is easily damaged when placed on site when detecting the drainage effect of a drainage device on stray current in a pipeline, and provides a device for detecting the drainage effect of a pipeline.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A device for detecting the drainage effect of a pipeline comprises a shell, a test structure arranged on the shell, a control device arranged in the shell, a display screen arranged on the surface of the shell, a dehumidification structure arranged in the shell, and a protective structure arranged at the bottom of the shell, wherein the test structure, the display screen, and the dehumidification device are connected to the control device.

[0007] The utility model utilizes a test structure to test the stray current of the pipeline, and the control device records, stores, and analyzes the test results, and displays the results on the display screen through the display screen. If the shell is placed on site for a long time, it is easy for moisture to enter the shell, which can easily cause damage to the electronic devices inside the shell. Therefore, a dehumidification device is provided in the shell to keep the inside of the shell dry. At the same time, since the pipeline drainage effect detection device provided by the utility model is actually used in a poor working environment on site, and mud, sand and stones can easily damage the surface of the shell, a protective structure is provided at the bottom of the shell, so that when the drainage effect of the pipeline is detected, the protective structure protects the shell from scratches or soaking in muddy water on site, thereby protecting the detection device.

[0008] Furthermore, the protective structure includes a bottom plate located at the bottom of the shell, a plurality of vertical rods arranged between the shell and the bottom plate, and a sealing sleeve and a spring mounted on the vertical rods. The bottom of the shell is provided with a first through hole for the vertical rod to pass through, one end of the vertical rod is fixedly connected to the bottom plate, the other end of the vertical rod is inserted into the first through hole and enters the shell, and a baffle is provided at the other end of the vertical rod, the sealing sleeve is located between the shell and the baffle, one end of the spring abuts against the outer bottom surface of the shell, and the other end of the spring abuts against the bottom plate.

[0009] The bottom plate is mounted on the bottom of the shell through a vertical rod. When the detection device is performing detection operations in a location with a poor environment, the bottom plate is placed on the ground or in muddy water to support the shell to prevent the shell from being scratched or soaked in muddy water. A spring is arranged between the bottom plate and the shell to balance and buffer. When the bottom plate is placed on an inclined bottom surface, the shell can maintain a relatively horizontal position. At the same time, if the detection device accidentally falls, the spring can play a certain buffering role. The sealing sleeve is made of elastic materials such as silicone and rubber, so that when the spring is deformed, the sealing sleeve can also be deformed together to maintain sealing.

[0010] Furthermore, the dehumidification structure includes a hole box arranged in the shell for placing the dehumidifier.

[0011] A dehumidifier may be placed in the well box to keep the interior of the housing dry.

[0012] Furthermore, the heat dissipation structure includes a fan arranged on the hole box and a plurality of heat dissipation plates arranged on the shell wall of the outer shell.

[0013] The heat sink is inserted on the shell wall of the outer shell, with a portion of the heat sink located inside the outer shell and a portion of the heat sink located outside the outer shell, so that the heat sink can transfer the heat inside the outer shell to the outside of the outer shell. The fan is used to accelerate the airflow in the hole box, which can not only accelerate the heat transfer, but also accelerate the air flow so that the dehumidification speed of the dehumidifier is faster and the effect is better.

[0014] Furthermore, the housing includes a shell body with an opening at the top and a cover body disposed on the shell body.

[0015] The cover is detachably connected to the shell, and the cover can be opened to facilitate replacement of the dehumidifier.

[0016] Furthermore, the hole box is arranged on the inner wall of the cover body, the fan is arranged at the bottom of the hole box, a mounting plate is arranged in the shell, the mounting plate is provided with a vent at the fan, the mounting plate is also provided with a plurality of ventilation holes, and the heat dissipation plate is located between the mounting plate and the bottom of the shell.

[0017] The mounting plate is used to mount the control device, and the orifice box and the fan are both located above the plate, so as to avoid mounting the control device on the bottom of the housing. Even if the bottom of the housing is damaged, it is not easy to cause the control device, the fan, and the orifice box to be soaked by water. The vents and holes on the mounting plate allow airflow to flow on both sides of the mounting plate. The heat sink is arranged on the portion of the housing below the mounting plate, that is, the mounting plate is arranged on the bottom of the housing or on the side wall close to the bottom.

[0018] Furthermore, the cover body is provided with a handle, the display screen is provided on the cover body, and the cover body is provided with a protective shell for protecting the display screen.

[0019] The cover is located on the top of the shell, and the display screen is arranged on the top of the shell for easy viewing. At the same time, a protective shell is arranged at the display screen. When the test device is used, the protective shell is covered to protect the display screen from damage.

[0020] Furthermore, the test structure includes wiring terminals, which include pipeline test terminals, drainage bed test terminals, reference electrode test terminals and test piece test terminals, and the wiring terminals are connected to the control device.

[0021] The pipeline power-on potential and AC interference voltage are tested through the pipeline test terminal and the reference electrode test terminal. The anode bed discharge current, anode bed working potential and anode bed open circuit potential are tested through the drainage bed test terminal. The pipeline power-off potential, DC stray current density and AC stray current density are tested through the test piece.

[0022] Furthermore, a timer is provided between the control device and the connection terminal.

[0023] The test time of the test terminal can be set according to the test requirements through the timer. The control device includes a storage module and an analysis module. In the storage module, the test related data is tested and stored. Through the analysis module, the test data is analyzed, and the power-off potential, DC interference current density, AC current density and discharge current data are analyzed. According to the judgment criteria, the pipeline drainage effect is analyzed. The analyzed data is presented on the display screen to show the test effect intuitively to the on-site test personnel.

[0024] Furthermore, it also includes a signal transmission module connected to the control device.

[0025] The signal transmission module can be used to upload and back up the data stored and analyzed by the storage module and the analysis module.
