[0022] (III) Beneficial effects

[0023] The present invention provides an outdoor power distribution cabinet with flood prevention and early warning function. It has the following beneficial effects:

[0024] (1) The present invention collects rainwater through a rainwater collecting component and introduces it into a heat dissipation box for storage. With the cooperation of a cooling water pipe, a transfer box, a cooling box and a water circulation power component, the rainwater is driven in a circulation manner to dissipate heat and cool the power distribution cabinet body, thereby achieving effective utilization of rainwater. During the process, the power distribution cabinet body remains closed, which can effectively prevent the external humid environment from interfering with the internal environment of the power distribution cabinet body.

[0025] (2) The present invention collects rainwater by coordinating the inclined rain guide plate, the water retaining plate frame, the drain hole, the filter screen plate, the docking plate, the perforated floating plate and the guide rod. When light impurities such as leaves fall on the rain collecting assembly, the perforated floating plate floats up and the light impurities such as leaves can be cleaned up under the impact of rainwater, thereby ensuring efficient collection of rainwater.

[0026] (3) The present invention achieves blocking of the butt pipe when the warning float is not affected by the buoyancy of rainwater by setting the vertical pole, the warning float and the counterweight plate, thereby preventing all the rainwater in the heat dissipation box from flowing into the transfer box. With the setting of the through groove, the heat conductive block and the second heat dissipation fin, it provides a guarantee for the rapid heat dissipation inside the power distribution cabinet body.

[0027] (4) The present invention ensures that the water in the transfer box can be smoothly transported to the cooling box by the water pump through the arrangement of the water pump, the three-way pipe, the first water inlet pipe, the second water inlet pipe, the water outlet pipe and the electromagnetic control valve. The arrangement of the piston plate frame, the return spring and the first rebound trigger button can effectively avoid the idling of the water pump when there is a lack of water in the transfer box. The arrangement of the second rebound trigger button can ensure that the water in the heat dissipation box can be smoothly transported to the cooling box, thereby providing protection for the heat dissipation of the distribution cabinet body, realizing the interval water supply of the heat dissipation box and ensuring the long-term heat dissipation of the distribution cabinet body.

[0028] (5) The present invention realizes the start mark of rainwater flow in the water pipe collected by the electronic liquid flow meter through the arrangement of an alarm switch, a partition, a single-head threaded rod, a fastening nut, a trigger plate, a third rebound-type trigger button and an electronic liquid flow meter. With the cooperation of the early warning float plate and the fourth rebound-type trigger button, the electronic liquid flow meter realizes the end mark of rainwater flow in the water pipe. The rainwater flow is effectively collected between the start mark and the end mark. In combination with the arrangement of the drainage pipe, the collection time of the rainwater flow is further extended, thereby providing effective data support for flood control and early warning.

When the filter plate 11 is blocked, the perforated floating plate 13 floats up, pushing the leaves and other light impurities on the filter plate 11 to rise and make them separate from the filter plate 11. When the perforated floating plate 13 is blocked, after the perforated floating plate 13 floats up, the leaves and other light impurities on the perforated floating plate 13 are directly washed off by the scouring of rainwater, and a blocking floating plate 16 is slidably installed inside the collecting basin 8, and a docking hole 17 compatible with the guide rod 14 is opened on the top of the blocking floating plate 16.

[0045] As a preferred solution, in order to collect and utilize rainwater, the heat sink 4 is fixedly connected to the back of the distribution cabinet body 1, and the bottom of the collection basin 8 is connected to the heat sink 4 through a water pipe 31. The front of the heat sink 4 and the back of the distribution cabinet body 1 are both provided with a connecting groove 35, and the inside of the groove 35 is sealed and fixedly connected with a heat-conducting block 36.

[0046] As a preferred solution, in order to realize water circulation drive, the right side of the heat dissipation box 4 and the transfer box 3 are connected through a docking pipe 26, and the water circulation power component 7 includes a mounting plate 19, and a water pump 20 is fixedly connected to the bottom of the mounting plate 19. The input end of the water pump 20 is connected to a three-way pipe 21, and one end of the three-way pipe 21 is connected to a first water inlet pipe 22. The output end of the water pump 20 is connected to a water outlet pipe 25, and one end of the water outlet pipe 25 is connected to the cooling box 2, and one end of the first water inlet pipe 22 is connected to the interior of the transfer box 3.

A first rebound trigger button 29 is fixedly connected to the bottom of the inner cavity of the transfer box 3. When the first rebound trigger button 29 is squeezed by the piston plate frame 27, the water pump 20 is started, and when the first rebound trigger button 29 is not squeezed by the piston plate frame 27, the water pump 20 is turned off.

[0048] In this embodiment, while achieving efficient collection of rainwater, rainwater can be used to dissipate heat for the closed power distribution cabinet body 1, thereby avoiding the influence of the external humid environment on the internal environment of the power distribution cabinet body 1 and achieving effective utilization of rainwater.

[0049] Embodiment 2

[0050] As an improvement of the previous embodiment, this embodiment is an outdoor power distribution cabinet with flood prevention and early warning, and also includes an electronic liquid flow meter 46 arranged on the surface of the water pipe 31. An alarm switch 42 is fixedly connected to the bottom of the collection basin 8. The electronic liquid flow meter 46 is used to collect rainwater flow in the water pipe 31 and communicate with the alarm switch 42. The alarm switch 42 is used to time-mark the time point when the electronic liquid flow meter 46 collects data, and communicate with the computer end, so that the computer end can display the rainwater flow collection period of the electronic liquid flow meter 46.

[0051] As a preferred solution, in order to realize the start mark of rainwater flow collection by the electronic liquid flowmeter 46, a partition 37 is fixedly connected to the rear side of the top of the inner cavity of the transfer box 3, and the partition 37 is arranged behind a number of cooling water pipes 6. Two single-head threaded rods 38 are fixedly connected to the top of the inner cavity of the transfer box 3, and the two single-head threaded rods 38 are both arranged behind the partition 37, and a trigger plate 39 is sleeved and slidably installed on the outer periphery of the two single-head threaded rods 38. A fastening nut 40 is threadedly installed on the bottom of the outer periphery of the two single-head threaded rods 38, and the fastening nut 40 is arranged below the trigger plate 39. A third rebound trigger button 41 is fixedly connected to the right side of the inner cavity of the transfer box 3, and the third rebound trigger button 41 is arranged behind the partition 37. When the third rebound trigger button 41 is squeezed by the trigger plate 39, the alarm switch 42 is activated to mark the start of data collection by the electronic liquid flowmeter 46. When the third rebound trigger button 41 is not squeezed by the trigger plate 39, the alarm switch 42 is turned off to end data collection.

[0052] It is further explained that during the start mark and end mark time periods, combined with the rainwater flow collected by the electronic liquid flow meter 46, a preliminary judgment can be made on the rainfall, providing data support for flood control and early warning.

[0053] As a preferred solution, in order to extend the collection time of rainwater flow data in the water pipe 31 , the right side of the transfer box 3 is connected to a drain pipe 43 , and the drain pipe 43 is arranged above the third rebound trigger button 41 .

[0054] As a preferred solution, in order to realize the end mark of rainwater flow collection by the electronic liquid flow meter 46, a vertical pole 32 is fixedly connected between the top and bottom of the inner cavity of the rainwater heat sink 4, and a warning float plate 33 is sleeved and slidably installed on the outer periphery of the vertical pole 32. A fourth rebound trigger button 47 is fixedly connected to the top of the inner cavity of the heat sink 4. When the fourth rebound trigger button 47 is squeezed by the warning float plate 33, the alarm switch 42 is turned off. At this time, the electronic liquid flow meter 46 ends the collection of rainwater flowing in the water pipe 31. As an end mark, the fourth rebound trigger button 47 starts the alarm switch 42 when it is not squeezed by the warning float plate 33.

[0055] As a preferred solution, in order to realize the intermittent release of rainwater collected in the heat dissipation box 4, the other end of the three-way pipe 21 is connected to the second water inlet pipe 23, and the surface of the second water inlet pipe 23 is provided with an electromagnetic control valve 24, and the right side of the early warning float 33 is fixedly connected to a counterweight plate 34, and the right side of the counterweight plate 34 is in sliding contact with the right side of the inner cavity of the heat dissipation box 4. The interior of the transfer box 3 is also fixedly connected to a second rebound trigger button 30. When the second rebound trigger button 30 is squeezed by the piston plate frame 27, the water pump 20 is started and the electromagnetic control valve 24 is opened. When the second rebound trigger button 30 is not squeezed by the piston plate frame 27, the water pump 20 is turned off and the electromagnetic control valve 24 is turned off. The magnetic control valve 24, when the warning float plate 33 is not affected by the buoyancy, the counterweight plate 34 blocks the docking pipe 26, so that when there is a lack of water in the transfer box 3, the reset spring 28 resets and pushes the piston plate frame 27 to squeeze the second rebound trigger button 30, so that the electromagnetic control valve 24 opens, and the water pump 20 extracts water from the heat sink 4 and transports it to the cooling box 2. After the water enters the transfer box 3 through the cooling water pipe 6, it squeezes the piston plate frame 27, so that the piston plate frame 27 squeezes the first rebound trigger button 29, and the release of rainwater stored in the heat sink 4 can be stopped. Through this reciprocating process, the intermittent release of rainwater in the heat sink 4 is achieved.

[0056] The advantage of the second embodiment over the first embodiment is that when the rainfall is heavy, effective judgment of the rainfall can be achieved, and intermittent release of rainwater stored in the heat dissipation box 4 can be achieved, providing delayed protection for the continuous heat dissipation of the distribution cabinet body 1.

[0057] When it rains, part of the rainwater falls into the collection basin 8 through the drain hole 10, and part of the rainwater flows to the top of the perforated floating plate 13, and then flows into the collection basin 8 through the filter screen plate 11. When the filter screen plate 11 is blocked, the perforated floating plate 13 floats up, pushing the leaves and other light impurities on the filter screen plate 11 to rise and make them separate from the filter screen plate 11. When the perforated floating plate 13 is blocked, after the perforated floating plate 13 floats up, the leaves and other light impurities on the perforated floating plate 13 are directly washed off by the rainwater, and the rainwater accumulates in the collection basin 8, causing the blocking floating plate 16 to float up, and the accumulated rainwater enters the heat sink 4 through the water guide pipe 31;

[0058] Rainwater is continuously accumulated in the heat dissipation box 4. After the early warning floating plate 33 contacts the rainwater, the rainwater pushes the early warning floating plate 33 upward, and the early warning floating plate 33 drives the counterweight plate 34 to move upward, leaking out of the docking tube 26. The accumulated rainwater falls into the transfer box 3 through the docking tube 26.

[0059] The rainwater squeezes the piston plate frame 27, and the piston plate frame 27 compresses the return spring 28, squeezing the first rebound trigger button 29, and the first rebound trigger button 29 starts the water pump 20. The rainwater in the transfer box 3 passes through the first water inlet pipe 22 and the three-way pipe 21, and is transported to the water outlet pipe 25 by the water pump 20, and then flows into the cooling box 2. As the rainwater in the cooling box 2 is continuously stored, the rainwater flows into the transfer box 3 again through the cooling water pipe 6. During the process, part of the cooling water pipe 6 performs heat exchange and cooling in the power distribution cabinet body 1;

[0060] When the rainfall is large, the rainwater level in the transfer box 3 continues to rise, pushing the trigger plate 39 to rise along the single-head threaded rod 38 until the trigger plate 39 squeezes the third rebound trigger button 41. At this time, the electronic liquid flow meter 46 starts to collect the rainwater flow in the water pipe 31 and communicates with the alarm switch 42. The alarm switch 42 communicates with the computer end, and the start mark of the flow collection time period is displayed on the computer end. As the rainfall continues, the early warning float 33 continues to rise until the early warning float 33 squeezes the fourth rebound trigger button 47. At this time, the electronic liquid flow meter 46 ends collecting the rainwater flow in the water pipe 31 and communicates with the alarm switch 42. The alarm switch 42 communicates with the computer end, and the end mark of the flow collection time period is displayed on the computer end. The collected data of the electronic liquid flow meter 46 is analyzed within the time period of the start mark and the end mark, providing data support for flood prevention and early warning at the installation point of the distribution cabinet body 1.

[0061] When there is no rainfall for a long time, the rainwater level in the heat sink 4 continues to drop, and the counterweight plate 34 blocks the docking pipe 26. When there is no rainfall for a long time, the rainwater level in the transfer box 3 continues to drop until the reset spring 28 in the transfer box 3 resets and pushes the piston plate frame 27 to squeeze the second rebound trigger button 30, so that the electromagnetic control valve 24 opens, and the water pump 20 extracts water from the heat sink 4 and transports it to the cooling box 2. After the water enters the transfer box 3 through the cooling water pipe 6, it squeezes the piston plate frame 27, so that the piston plate frame 27 squeezes the first rebound trigger button 29, and the release of rainwater stored in the heat sink 4 can be stopped. Through this reciprocating process, the intermittent release of rainwater in the heat sink 4 is achieved.
