[0002] With the continuous growth of my country's economy, the demand for clean electricity and energy continues to increase. In recent years, the number of power projects under construction in my country has been increasing. Ultra-high voltage direct current (UHVDC) transmission lines, due to their large-scale, long-distance, and high-efficiency power transmission requirements, are widely used in strategic power deployments such as the West-to-East Power Transmission Program. Monitoring and research on environmental factors such as the combined electric field strength of HVDC transmission lines is also increasing. Currently, DC combined electric field strength detection systems primarily rely on brushless motor probes with spherical shafts. These probes typically have poor rainproofing and are easily damaged by sudden rain events. Long-term combined electric field strength studies are typically conducted in sparsely populated suburban areas, requiring 7-10 consecutive days of testing. Sudden weather changes during monitoring can make it difficult to quickly rescue equipment, resulting in a high rate of probe returns for repair. Furthermore, their high price significantly increases testing costs.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 , a rainproof protection device for a DC synthetic field strength test probe includes a transparent cover 100 and a test platform 200, the transparent cover 100 is installed on the top of the test platform 200, and a control component 300 is installed at the bottom of the test platform 200, and a moisture-proof component 310 is installed in the control component 300 box, the moisture-proof component 310 includes a drying fan 301, a motor 302 and a heating plate 303, the motor 302 is installed on the bottom inner wall of the control component 300, the drying fan 301 is installed on the top of the motor 302, and the heating plate 303 is installed on the top of the drying fan 301, which can heat and discharge the humid air in the cover, and a cover expansion joint 202 is provided around the top of the test platform 200, and the transparent cover 100 is movably installed in the cover expansion joint 202, a lifter 304 is installed on the inner wall of the control component 300, and the output end of the lifter 304 is connected to one side of the transparent cover 100.

[0023] In the present invention, a leveling device 201 is installed on the test platform 200 . The leveling device 201 is a leveling plate. Leveling screws 204 are installed on the leveling plate. The leveling screws 204 extend outside the test platform 200 .

[0024] In the present invention, a high-power fan 203 is installed on the moisture-proof component 310, and a heat dissipation circular hole is provided at the top center position of the test platform 200, and the heat dissipation circular hole is adapted to the high-power fan 203, and is used to discharge humid air from the circular hole in the top iron plate, and at the same time discharge air upward to prevent rainwater from entering the cover from the top circular hole.

[0025] In the present invention, the control component 300 is electrically connected to the rain detection component 400, and the rain detection component 400 is located outside the control component 300. After the rain detection component senses rain, the moisture-proof component starts the heating device to heat the humid air in the cover.

[0026] In the present invention, a tester probe is installed at the top center of the test platform 200 .

[0027] In the present invention, the transparent cover 100 is a square cover made of transparent acrylic or glass material, which is convenient for observing the internal probe situation.

[0028] In the present invention, the rain detection component 400 includes an optical rain sensor.

[0029] In the present invention, a lifting component 500 is provided at the bottom of the control component 300, and the lifting component 500 is an electric lifter. A laser alarm is installed on the control component 300. The lifting component can automatically lift the test platform when there is water on the ground to prevent flooding. Through the setting of the laser alarm, the test time can be unattended for a long time. If someone approaches or damages it, an "electrical hazard" alarm can be issued.

[0030] The present invention further includes an energy supply component, which is connected to the control component 300, the moisture-proof component 310, the rainfall detection component 400 and the motor 302 respectively.

[0031] The present invention: when in use, the test platform and the part above it remain above the ground, and the part below is inserted into the ground. After using the leveling device 201 and the leveling screws 204 to keep the platform relatively level, the test probe is placed in the central part of the test platform 200. When it rains, the rain detection component 400 detects rain outside the platform. The transparent cover 100, the control component 300, the moisture-proof component 310 and the rain detection component 400 are communicated and connected. The control component 300 is configured to start the transparent cover 100 and the moisture-proof component 310 according to the detection result of the rain detection component 400. After receiving the instruction, the transparent cover 100 is lifted to the top of the test platform 200 through the lifting device 304 on the four side walls of the control component through the cover expansion joint 202, and lifts the test plate a certain distance.

[0032] The transparent cover in this embodiment can prevent most rainwater and dust from entering the test probe. On this basis, the rainfall detection component 400 detects the ambient rainfall outside the cover in real time, and transmits the detection result to the control component 300. The control component 300 processes the detection result, converts the detection result into an instruction and transmits it to the moisture-proof component to control its startup or shutdown, and adjusts the temperature and air volume of the moisture-proof component 310, thereby automatically preventing external humid air and rainwater from entering the cover through the circular hole in the upper iron plate, thereby realizing the rainproof function.

[0033] In order to further prevent damage to the test probe in a humid environment, the synthetic field strength test probe rain protection device in this embodiment also includes a moisture-proof component 310, which is arranged in the control component and is used to heat the humid gas entering the cover to ensure that the gas in contact with the main variable temperature meter is dry gas, thereby reducing the impact of humid gas and rain.

[0034] Specifically, in this embodiment, the moisture-proof component 310 includes multiple heat-conducting parts, a high-power fan and an electric motor. The heat-conducting parts are arranged above the drying fan 301. The drying fan 301 is used to blow hot air from the bottom upward into the cover body, so that the humid gas is converted into dry gas, and discharged out of the cover through the circular hole in the middle of the top test plate, thereby reducing the impact of the humid gas on the main transformer temperature gauge.

[0035] The rotation speed and air volume of the drying fan 301 can be dynamically adjusted according to the detection result of the rain detection device, so that the air volume discharged from the top circular hole can just blow away the falling rainwater and prevent the rainwater from entering the inside of the cover.

[0036] To power the DC synthetic field strength test probe rain protection device, this embodiment also includes an energy supply assembly. Specifically, the energy supply assembly is connected to the control assembly 300, the moisture-proof assembly 310, the rainfall detection assembly 400, and the motor, providing energy. Specifically, the energy supply assembly can be connected to the test probe's power supply circuit or a battery-powered assembly. Preferably, the energy supply assembly can be a solar energy supply assembly, which stores energy when there is sufficient sunlight and converts it into electrical energy to power the main variable temperature meter rain protection device, ensuring the environmental friendliness of the energy supply to the synthetic field strength test probe rain protection device.

[0037] In this embodiment, in order to accurately detect the amount of rainfall, the rainfall detection component 400 includes an optical rainfall sensor, which can detect the amount of external rainfall through changes in light.

[0038] As a preferred solution, the weather station of the test system can also be directly connected to obtain real-time data. Multiple rainfall detection components 400 can also be provided to detect rainfall conditions at multiple locations to improve the accuracy of the detection results.

[0039] In order to increase the service life of the cover and prevent the cover from being eroded by rainwater, the cover 100 in this embodiment can also be made of stainless steel to ensure that the cover is not easily eroded by rainwater. The shape of the cover can also be other shapes such as a cylinder.

[0040] Example 2:

[0041] The basic structure of the DC synthetic field strength test probe rainproof protection device provided in this embodiment is the same as that in Example 1, with only some structures different. This embodiment only describes the structure that is different from the DC synthetic field strength test probe rainproof protection device provided in Example 1.

[0042] In this embodiment, the circular hole of the upper test plate is protected from rain by a mechanical method. When the rainfall detection component 400 detects heavy rain, the rainproof umbrella outside the cover is automatically popped up to cover the circular hole.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
