[0018] Example 1: Please refer to Figures 1 to 8 : The present invention proposes a rainproof wall-mounted power cabinet, comprising: a box body 1; the box body 1 adopts a rectangular groove structure, and a group of penetrating circular through-groove structures are opened on both sides of the top of the box body 1, and air vent structures are opened on the left and right sides of the box body 1. Four groups of penetrating circular through-groove structures are opened in a rectangular array around the inner wall of the box body 1; slide rails 102 are fixedly arranged on the front and rear sides of the inner wall of the box body 1, and the front and rear two groups of slide rails 102 are respectively arranged on both sides of the ventilation hole on one side of the box body 1; a baffle 103 with a rectangular plate structure is slidably arranged between the front and rear two groups of slide rails 102, and the outer wall of the baffle 103 is in contact with the inner wall of the box body 1.

[0019] Among them, a box door 101 with a rectangular plate structure is rotatably arranged on the front side of the box body 1; a group of sliding rods 104 with a cylindrical structure are slidably arranged in the circular through grooves on both sides of the top of the box body 1, and a spring is sleeved on the outer side of the sliding rod 104, and the bottom ends of the two groups of sliding rods 104 are respectively fixedly connected to the two groups of baffles 103; an inverted V-shaped top plate 105 is fixedly arranged on the top of the two groups of sliding rods 104; a group of water collecting troughs 106 are fixedly arranged on the front and rear sides of the top plate 105, and the water collecting troughs 106 adopt a U-shaped plate structure; a group of side rods 111 with a rectangular rod structure are fixedly arranged on the bottom of both sides of the top plate 105; a group of collecting troughs 2 are fixedly arranged on the bottom of the side rods 111.

[0020] Among them, a top rod 107 of an L-shaped rod structure is fixedly arranged on the front side of the two groups of sliding rods 104; a group of connecting rods 108 of a cylindrical structure are slidably arranged in the four groups of circular through grooves inside the box body 1, and a spring is sleeved on the outer side of the connecting rod 108; a sliding frame 109 is fixedly arranged on the front side of the four groups of connecting rods 108, and the sliding frame 109 adopts a rectangular frame structure, and the outer wall of the sliding frame 109 is in contact with the inner wall of the box body 1; a group of connecting blocks 110 of a wedge block structure are fixedly arranged on both sides of the rear wall of the sliding frame 109, and the bottom end of the top rod 107 is in contact with the connecting block 110.

[0021] Specific usage and function of this embodiment: In the present invention, after the box body 1 is installed in the use area, when it rains, rainwater falls on the top plate 105, and flows along the top plate 105 to the water collecting grooves 106 on the front and rear sides, and flows outward along the two sides of the two groups of water collecting grooves 106 respectively, and the rainwater flows into the two groups of collecting grooves 2 respectively. As the amount of rainwater increases, the gravity of the collecting grooves 2 increases, thereby driving the top plate 105 and the two groups of sliding rods 104 to slide downward along the circular through groove on the top of the box body 1. In the process of the two groups of sliding rods 104 sliding downward, the two groups of baffles 103 and the two groups of top rods 107 are synchronously driven to move downward. In the process of the two groups of baffles 103 moving downward along each group of slide rails 102, they can move to the inner side of the ventilation holes on both sides of the box body 1, so that the ventilation holes of the box body 1 are ventilated by the two groups of baffles 103. The two groups of top rods 107 are blocked so that rain cannot enter the interior of the box body 1. During the downward movement of the two groups of top rods 107, the two groups of top rods 107 can respectively contact the inclined structures of the two groups of connecting blocks 110, thereby pushing the two groups of connecting blocks 110 to move forward, and making each group of connecting rods 108 and the sliding frame 109 move forward along the circular through groove inside the box body 1, so that the sliding frame 109 moves to the inner side of the connection between the box door 101 and the box body 1, and the gap between the box door 101 and the box body 1 is blocked to prevent rainwater from entering the box body 1 through the gap between the box door 101 and the box body 1, so that the box body 1 is in a sealed state, which greatly improves the sealing performance of the box body 1, effectively prevents rainwater from entering the box body 1, improves the rainproof effect of the box body 1, and achieves the purpose of automatic protection according to weather conditions without manual intervention.

[0022] Example 2: Based on Example 1, please refer to Figures 1 to 8 : Among them, the collecting tank 2 adopts a rectangular groove structure; the outer side of the collecting tank 2 is connected to a circulating pipe 201, and part of the circulating pipe 201 is arranged on the inner side of the box body 1; the bottom of the collecting tank 2 is connected to a piston cylinder 202 with a cylindrical structure, and a one-way valve structure is arranged between the piston cylinder 202 and the collecting tank 2, the circulating pipe 201 is connected to the piston cylinder 202, and a one-way valve structure is arranged between the circulating pipe 201 and the piston cylinder 202, and a circular through groove structure is opened at the bottom of the piston cylinder 202.

[0023] Among them, a piston rod 203 with a cylindrical structure is slidably arranged in the circular through groove at the bottom of the piston cylinder 202, and a spring is sleeved on the outer side of the piston rod 203; a piston plate 204 with a circular plate structure is fixedly arranged on the top of the piston rod 203, and the outer wall of the piston plate 204 is in contact with the inner wall of the piston cylinder 202; a group of cylindrical transmission rods 205 are rotatably connected at the bottom of the two groups of collecting tanks 2; a fan blade 206 is fixedly arranged at the front end of the transmission rod 205; four groups of wedge-shaped block driven blocks 207 are fixedly arranged at the rear side end of the transmission rod 205 in a ring array, and the driven blocks 207 at the rear ends of the two groups of transmission rods 205 are oriented in opposite directions.

[0024] The specific usage and function of this embodiment: when the amount of rainwater in the collection tank 2 increases, water can accumulate in the collection tank 2. Under the action of wind, the two sets of fan blades 206 rotate. The fan blades 206 rotate while driving the transmission rod 205 to rotate, and synchronously drive the groups of driven blocks 207 at the rear end of the transmission rod 205 to rotate. During the rotation of the driven block 207, the inclined surface structure of the driven block 207 can contact the bottom end of the piston rod 203, thereby pushing the piston rod 203 along the circular through groove of the piston cylinder 202. The piston plate 204 slides upward and simultaneously drives the piston plate 204 to slide upward inside the piston cylinder 202. During the upward movement of the piston plate 204, the rainwater inside the piston cylinder 202 can be squeezed into the circulation pipe 201, so that the rainwater can enter the interior of the box body 1 along the circulation pipe 201 and absorb the heat generated inside the box body 1. When the follower block 207 is out of contact with the piston rod 203, the piston rod 203 drives the piston plate 204 to slide downward under the action of the spring, so that the water flow in the collection tank 2 can be sucked into In the piston cylinder 202, when the fan blades 206 drive the driven block 207 to rotate continuously, the collecting tank 2 can be continuously circulated along the circulation pipe 201. In this process, the water flow in the circulation pipe 201 can be used to dissipate heat to the inside of the box body 1, so as to avoid the box body 1 being closed and resulting in a reduced heat dissipation effect. The circulating water returns to the collecting tank 2 through the circulation pipe 201 for re-cooling, thereby completing the entire circulation process, ensuring that the inside of the box body 1 can be ventilated and heat-dissipated under any circumstances, ensuring the normal operation of the equipment inside the box body 1, and extending the service life of the equipment. Moreover, the device does not need to install any additional equipment, and can fully realize automatic operation, with extremely low use and maintenance costs. Since the inclined surfaces of the driven blocks 207 on the rear sides of the two sets of transmission rods 205 are in different directions, no matter the wind direction drives the two sets of fan blades 206 to rotate in any direction, each set of driven blocks 207 on one side can play a role in contacting the piston rod 203, so that the rainwater in the circulation pipe 201 on one side can keep circulating, and the heat dissipation effect of the device is maintained.
