[0014] This invention also discloses a method for rain testing of field equipment, specifically including the following steps: Step 1: Place the equipment body on the base using hoisting equipment or a robotic arm.

[0015] Beneficial effects This invention provides a rain testing device and method for field equipment. Compared with the prior art, it has the following advantages: (1) By setting up a test mechanism, the rain system is used to simulate the rain environment and the blower system is used to simulate the wind environment, thereby improving the simulation accuracy. At the same time, the base and the block are used to support the equipment body, and the movement of the block is used to achieve a complete rain test on one side surface, thereby avoiding the problem of being blocked and unable to conduct the rain test.

[0016] (2) By setting up a steering component, the steering motor drives the carrier plate to rotate, thereby realizing the rotation of the equipment body surface around the perimeter and at both ends, thus enabling the equipment body surface to undergo a full rain test. Furthermore, the support of the casters facilitates the improvement of the carrier plate's load-bearing capacity and rotation smoothness. At the same time, the holes on the carrier plate facilitate the dripping of liquid water, which is conducive to the verification of the test results.

[0017] (3) By setting up a drive unit, the combination of the fixed rail and the upper and lower sets of rollers can facilitate the base to drive the equipment body to move closer to the blower system. On the other hand, it can support the bracket and reduce the wear of movement through the rolling of the rollers. At the same time, it can reduce the force on the teeth between the gear and the rack, thereby avoiding the problem of tooth breakage.

[0018] (4) By setting up adjustment components, the extension and retraction of the telescopic rods are used to clamp the two ends of the equipment body. Through the drive of the rotary cylinder and the support of the rotating sleeve, the four sides of the equipment body surface are turned towards the blower system in turn, so as to conduct a smooth rain test on the surface.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-6 This invention provides a technical solution: a rain testing device for field equipment. Example 1: The test chamber 1 includes a water tank and a pump on its exterior. Inside the chamber 1 is a testing mechanism, including a blower system 2 mounted on one side of the inner wall. The blower system 2 includes a heated blower and an airflow regulator (similar to an automotive air conditioning vent regulator). The airflow regulator consists of a frame and two sets of mutually perpendicular louvers located inside the frame. The louvers are driven by a waterproof motor to adjust the airflow direction. Above the blower system 2 is a rain system 3, consisting of a water tower connected to the pump and a drip plate. The drip plate is positioned on the test chamber via a lifting hoist. For details regarding the interior of test chamber 1 and the specific structure and implementation of the drip plate in the rain system 3, please refer to the lifting structure and drip plate disclosed in utility model publication CN205426429U. The water tower simulates a rainy environment through water storage and gravitational potential energy. As a preferred method, a pressurization device can also be installed inside the water tower to enhance the kinetic energy of the water droplets. The rain system 3 is located above the interior of test chamber 1, and a base 4 is located below the rain system 3. The outer surface of the base 4 is movably connected to the interior of test chamber 1. The top of the base 4 is movably connected to the equipment body 5. The equipment body 5 and the blower system 2 are located on opposite sides below the rain system 3. Both sides of the outer surface of the equipment body 5 are movably connected to stacked blocks 8. One side of the block 8 is in contact with the surface of the equipment body 5. A connecting block 9 is fixedly connected to the outer surface of the block 8. A groove 10 is provided at the bottom of the connecting block 9. The groove 10 is set with its opening facing downward to prevent liquid water from entering during rain testing and to facilitate the dripping of any liquid water that enters. A slider 11 is slidably connected inside the groove 10. The outer surface of the slider 11 is fixedly connected to the top of the adjacent connecting block 9. A lead screw 12 is threaded through the body of the slider 11. One end of the lead screw 12 is fixedly connected to a reciprocating motor 13 through a coupling. The reciprocating motor 13 is made of servo motor and is externally set. It has a waterproof shell and is electrically connected to an external control circuit. The outer surface of the reciprocating motor 13 is fixedly connected to the inside of the slide groove 10. The outer surface of the base 4 is provided with two sets of slide rails 14 that are perpendicular to each other. One end of the slide rail 14 perpendicular to the base 4 is fixedly connected to the outer surface of the base 4. Linear motors 15 are slidably connected to the outer surfaces of both sets of slide rails 14. The linear motors 15 have a self-locking function, are provided with a waterproof shell, and are electrically connected to an external control circuit. The top of the lower linear motor 15 is fixedly connected to the bottom of the upper slide rail 14 through a connecting rod 16. The outer surface of the upper linear motor 15 is fixedly connected to the outer surface of the bottom connecting block 9.

[0023] In this embodiment, the equipment body 5 is placed on the base 4. Then, the lower linear motor 15 moves, causing the connecting block 9 to drive the abutment block 8 to adhere to the surface of the equipment body 5. Then, driven by the base 4, it moves closer to the blower system 2. Next, the rain system 3 provides falling water droplets into the test chamber 1. Then, the blower system 2 blows the water droplets onto the surface of the equipment body 5. At the same time, during the rain process, the reciprocating motor 13 drives the lead screw 12 to rotate. Through the threaded connection between the lead screw 12 and the slider 11, the slider 11 is fixed by the lower connecting block 9 or the linear motor 15, thereby changing the relative position of the slider 11 in the upper slide groove 10. That is, the lead screw 12 drives the corresponding upper connecting block 9 to slide left and right along the axial direction, thereby causing the upper connecting block 9 to drive the corresponding abutment block 8 to slide along the surface of the equipment body 5. This abuts the equipment body 5 in a figure-eight or inverted figure-eight shape, avoiding constant shading of some areas of the surface of the equipment body 5, which would lead to insufficient rain test results.

[0024] Example 2: A steering assembly 6 is provided on the exterior of the equipment body 5. The steering assembly 6 includes a bracket 61, the outer surface of which is movably connected to the interior of the test chamber 1. A steering motor 63 is fixedly connected to the outer surface of the bracket 61. The steering motor 63 is made of a servo motor and is electrically connected to an external control circuit. A carrier plate 64 is fixedly connected to the output end of the steering motor 63. The steering motor 63 is fixedly connected to the carrier plate 64 through a reducer to drive the carrier plate 64 to rotate at a low speed and stably. It is also fixedly connected to the bracket 61 through a waterproof shell. The carrier plate 64 has a through hole to facilitate the dripping of liquid water. The top of the carrier plate 64 is fixedly connected to the bottom of the base 4. Universal wheels 65 are fixedly connected to all four sides of the top of the bracket 61. The universal wheels 65 can improve the load-bearing capacity and steering smoothness of the carrier plate 64. The outer surface of the caster wheel 65 is movably connected to the outer surface of the carrier plate 64. Two abutment plates 66 are provided on the outside of the bracket 61. The abutment plates 66 abut against both ends of the equipment body 5 to prevent the equipment body 5 from being misaligned due to centrifugal force during rotation. The outer surfaces of the two abutment plates 66 are movably connected to both sides of the outer surface of the base 4 and both ends of the equipment body 5, respectively. Folding strips 67 are slidably connected to the outer surfaces of the two abutment plates 66. The folding strips 67 limit the abutment plates 66 and improve their load-bearing capacity. The outer surfaces of the two folding strips 67 are fixedly connected to both sides of the outer surface of the base 4, respectively. Lifting rods 68 are fixedly connected to the outer surfaces of the two abutment plates 66. The lifting rods 68 are made of electric push rods and are electrically connected to the external control circuit. One end of each lifting rod 68 is fixedly connected to both sides of the outer surface of the base 4.

[0025] In this embodiment, after a rain test is conducted on all four sides of the equipment body 5, the steering motor 63 drives the carrier plate 64 to rotate via the reducer. The caster wheel 65 bears the load on the carrier plate 64 and assists in its rotation, causing the base 4 to drive the equipment body 5 to move synchronously. This allows both ends of the equipment body 5 to face the blower system 2 in sequence for the rain test. Before rotation, the output end of the lifting rod 68 extends to raise the abutment plate 66, which then abuts against both ends of the equipment body 5 to prevent axial misalignment of the equipment body 5 due to centrifugal force during rotation.

[0026] Example 3: A drive unit 62 is provided on the outside of the bracket 61. The drive unit 62 includes two fixed rails 621. One side of the fixed rails 621 is fixed to the inside of the test chamber 1 by angle iron. The outer surfaces of the two fixed rails 621 are fixedly connected to the inside of the test chamber 1. A slide 622 is fitted on the outside of each of the two fixed rails 621. The outer surface of the slide 622 is fixedly connected to the bottom of the bracket 61. Two sets of rollers 623 are rotatably connected to the outer surface of the slide 622. The lower roller 623 is shaped like a train wheel to avoid the angle iron from abutting and restricting the contact. The outer surfaces of the two sets of rollers 623 are respectively connected to the top of the fixed rail 621. The main body and bottom are movable connections. The external of the fixed rail 621 is equipped with a drive motor 624. The drive motor 624 is made of servo motor and is electrically connected to the external control circuit. The outer surface of the drive motor 624 is fixedly connected to the outer surface of the bracket 61. The output end of the drive motor 624 is fixedly connected to the gear 625. The drive motor 624 is fixedly connected to the gear 625 through a reducer so as to smoothly drive the equipment body 5 close to the blower system 2. It is also fixedly connected to the bracket 61 through a waterproof shell. The outer surface of the gear 625 meshes with a rack 626. The outer surface of the rack 626 is fixedly connected to the inside of the test chamber 1.

[0027] In this embodiment, when the equipment body 5 needs to be driven close to the blower system 2, the drive motor 624 drives the gear 625 to rotate. Through the meshing of the gear 625 and the rack 626, the bracket 61 moves with the equipment body 5 through the base 4. During the movement, the upper and lower sets of rollers 623 cooperate with the fixed rail 621 to bear the weight of the bracket 61 and guide the movement of the bracket 61, thereby avoiding the problem of the gear 625 and the rack 626 breaking due to excessive force.

[0028] Example 4: An adjustment assembly 7 is provided on the outside of the equipment body 5. The adjustment assembly 7 includes two telescopic rods 71, which are made of hydraulic rods and connected to an external control circuit. The two telescopic rods 71 ​​are respectively located on the outer sides of both ends of the equipment body 5. A rotating sleeve 72 is fixedly connected to the output end of each of the two telescopic rods 71. A clamping plate 73 is rotatably connected to one end of each of the two rotating sleeves 72. One side of the clamping plate 73 is in contact with the end of the equipment body 5, and the contact friction is increased by a rubber material to improve the stability of clamping. At the same time, it is connected to the rotating sleeve 72 by axial limiting measures such as bearings. The outer surfaces of 73 are movably connected to both ends of the equipment body 5. Rotary cylinders 74 are fixedly connected inside the two rotating sleeves 72. The rotary cylinders 74 are connected to the external control circuit. The output end of the rotary cylinders 74 is fixedly connected to the outer surface of the clamping plate 73. Columns 75 are fixedly connected to the outer surfaces of the two telescopic rods 71. The bottom ends of the two columns 75 are fixedly connected to the inside of the test chamber 1. Tripods 76 are fixedly connected to three sides of the outer surfaces of the two columns 75. The tripods 76 improve the stability of the support of the columns 75 for the telescopic rods 71. The bottoms of the tripods 76 on both sides are fixedly connected to the inside of the test chamber 1.

[0029] In this embodiment, when it is necessary to adjust the position around the surface of the equipment body 5, the output end of the telescopic rod 71 extends, causing the rotating sleeve 72 to drive the clamping plate 73 to move and clamp the end of the equipment body 5. Subsequently, the output end of the rotating cylinder 74 drives the equipment body 5 to rotate through the clamping plate 73, so that different areas of the surface of the equipment body 5 face the blower system 2 in sequence, thereby conducting a thorough rain test. During the rotation, the tripod 76 improves the force and balance of the telescopic rod 71 through the column 75.

[0030] This invention also discloses a method for rain testing of field equipment, specifically including the following steps: Step 1: Place the equipment body 5 on the base 4 using hoisting equipment or a robotic arm. Then, the linear motor 15 slides down, causing the connecting block 9 to drive the abutment block 8 to abut against the surface of the equipment body 5. Then, the drive motor 624 drives the bracket 61 to move the equipment body 5 closer to the blower system 2 through the meshing of the gear 625 and the rack 626. Step 2: The rain system 3 drips water into the interior of the test chamber 1 and blows it onto the surface of the equipment body 5 through the blower system 2 for a rain test. At the same time, the reciprocating motor 13 drives the lead screw 12 to rotate and drive the slider 11 to slide the connecting block 9, so that the connecting block 9 drives the abutment block 8 to move synchronously, so that the abutment block 8 forms an V-shape to abut against the equipment body 5. After a period of testing, the top connecting block 9 remains stationary while the other connecting blocks 9 move, so that the abutment block 8 forms an inverted V-shape to abut against the equipment body 5. After a period of testing, the linear motor 15 above drives all the connecting blocks 9 to slide, and then the rain test is carried out. Step 3: After conducting a rain test on one side of the equipment body 5, the output end of the telescopic rod 71 extends, so that the clamping plate 73 clamps both ends of the equipment body 5. Then, the rotating cylinder 74 drives the equipment body 5 to rotate, so as to conduct a rain test on all four sides of the surface of the equipment body 5. Subsequently, the steering motor 63 drives the carrier plate 64 to rotate, so that both ends of the equipment body 5 face the blower system 2 respectively, thereby conducting a rain test on both ends.

A rotary cylinder (74) is fixedly connected inside the two rotating sleeves (72). The output end of the rotary cylinder (74) is fixedly connected to the outer surface of the clamping plate (73).

8. The rain testing device for field equipment according to claim 7, characterized in that: The outer surfaces of the two telescopic rods (71) are fixedly connected with columns (75), the bottom ends of the two columns (75) are fixedly connected to the interior of the test chamber (1), and tripods (76) are fixedly connected to the three sides of the outer surfaces of the two columns (75). The bottom of the tripods (76) on both sides are fixedly connected to the interior of the test chamber (1).

9. A method for rain testing of field equipment, using the rain testing device for field equipment as described in any one of claims 8, characterized in that: Specifically, the following steps are included: Step 1: Place the equipment body (5) on the base (4) using hoisting equipment or robotic arm. Then, the linear motor (15) slides down, causing the connecting block (9) to drive the abutment block (8) to abut against the surface of the equipment body (5). Then, the drive motor (624) drives the bracket (61) to move the equipment body (5) closer to the blower system (2) through the meshing of gears (625) and racks (626). Step 2: The rain system (3) drips water into the interior of the test chamber (1) and blows it onto the surface of the equipment body (5) through the blower system (2) to conduct a rain test. At the same time, the reciprocating motor (13) drives the lead screw (12) to rotate and drive the slider (11) to drive the connecting block (9) to slide, so that the connecting block (9) drives the abutment block (8) to move synchronously, so that the abutment block (8) forms an V-shape to abut against the equipment body (5). After a period of testing, the uppermost connecting block (9) remains stationary while the other connecting blocks (9) move, so that the abutment block (8) forms an inverted V-shape to abut against the equipment body (5). After a period of testing, the upper linear motor (15) drives all the connecting blocks (9) to slide, and then the rain test is carried out. Step 3: After conducting a rain test on one side of the equipment body (5), the output end of the telescopic rod (71) extends, so that the clamping plate (73) clamps both ends of the equipment body (5). Then, the equipment body (5) is rotated by the rotary cylinder (74) to conduct a rain test on all four sides of the surface of the equipment body (5). Subsequently, the steering motor (63) drives the carrier plate (64) to rotate, so that both ends of the equipment body (5) face the blower system (2) respectively, thereby conducting a rain test on both ends.
