[0033] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0034] The present disclosure provides an electric control cabinet, such as Figure 1 As shown, the electric control cabinet comprises a ceiling 1, a cabinet body 2 and a moisture-proof component 3. The ceiling 1 covers the top of the cabinet body 2 and is connected to the cabinet body 2.

[0035] Figure 2 for Figure 1 The cross-sectional view along the AA direction, combined with Figure 2 The top surface of the ceiling 1 has a water drop hole 10. The side wall of the cabinet 2 has a cavity 200 and a heat dissipation hole 201, and the cavity 200 is connected to the water drop hole 10 and the heat dissipation hole 201 respectively. The heat dissipation hole 201 penetrates the side wall.

[0036] The moisture-proof component 3 is located in the cavity 200 , and is used to close the heat dissipation holes 201 after rainwater enters the cavity 200 .

[0037] When the electric control cabinet provided by the embodiment of the present disclosure is used, since the side wall of the cabinet body 2 in the electric control cabinet has the heat dissipation holes 201 , the heat inside the cabinet body 2 can be dissipated through the heat dissipation holes 201 .

[0038] Since the side wall of the cabinet 2 in the electric control cabinet also has a cavity 200, and the electric control cabinet also includes a moisture-proof component 3, the moisture-proof component 3 is located in the cavity 200, and the moisture-proof component 3 is used to close the corresponding heat dissipation hole 201 after water enters the cavity 200. Therefore, when it rains, the water hole 10 can introduce rainwater into the cavity 200. When rainwater enters the cavity 200, the moisture-proof component 3 can block the heat dissipation hole 201 to prevent rainwater or water vapor from entering the cabinet 2 from the heat dissipation hole 201, reduce the impact of rainwater or water vapor on the electrical components in the cabinet 2, and thus extend the service life of the electrical components.

[0039] That is to say, when it rains, the electric control cabinet provided in the embodiment of the present disclosure can shield the heat dissipation holes 201 through the moisture-proof component 3 to reduce the invasion of water vapor and the like into the cabinet body 2 .

[0040] Optionally, the moisture-proof assembly 3 includes a baffle 31 and a counterweight 32, and the baffle 31 can move between a first position and a second position relative to the cabinet 2. When the baffle 31 is in the first position, the baffle 31 is misaligned with the heat dissipation hole 201, and when the baffle 31 is in the second position, the baffle 31 blocks the heat dissipation hole 201.

[0041] The counterweight 32 is located at the bottom of the baffle 31 and connected to the baffle 31 . The counterweight 32 can absorb moisture to increase its own weight, so as to drive the baffle 31 to move from the first position to the second position.

[0042] In the above implementation, the baffle 31 is used to move relative to the cabinet 2 so as to cover the heat dissipation holes 201 on rainy days. The counterweight 32 is used to absorb water and increase weight on rainy days so as to drag the baffle 31 from the first position to the second position.

[0043] Figure 3 for Figure 2 Schematic diagram of the structure of the moisture-proof component in the direction perpendicular to the paper surface, combined with Figure 3 Optionally, the moisture-proof component 3 further includes a slider 33, a slide bar 34 and an elastic reset member 35. The slider 33 is connected to the top of the baffle 31, and is sleeved outside the slide bar 34 and slidably connected to the slide bar 34. Both ends of the slide bar 34 are respectively connected to the cabinet 2, and the length direction of the slide bar 34 is the height direction of the cabinet 2 (the direction from the bottom to the top of the cabinet 2).

[0044] In the above implementation, the slider 33 is connected to the baffle 31 to move synchronously with the baffle 31. The slide bar 34 is used to guide the slider 33 so that the slider 33 can only move along the length direction of the slide bar 34, thereby preventing the baffle 31 from deflecting during movement.

[0045] The elastic reset member 35 is used to reset the slider 33 so that the baffle 31 can automatically return to the first position from the second position.

[0046] When it rains, rainwater flows into the cavity 200 along the drain hole 10 and falls onto the counterweight 32. The weight of the counterweight 32 absorbs rainwater and gradually increases. The counterweight 32 drives the baffle 31 to move downward toward the bottom of the cabinet 2, so that the baffle 31 switches from the first position to the second position. The baffle 31 closes the heat dissipation hole 201 to prevent external water vapor from entering the cabinet 2 and causing adverse effects on the electronic components inside the cabinet 2.

[0047] When the rain stops, the counterweight 32 gradually dries up, the weight of the counterweight 32 gradually decreases, and the slider 33 moves upward toward the top of the cabinet 2 under the elastic force of the elastic reset member 35. When the elastic force provided by the elastic reset member 35 is greater than the weight of the counterweight 32, the slider 33 drives the baffle 31 to move upward, and the baffle 31 switches from the second position to the first position, thereby opening the heat dissipation hole 201, facilitating air exchange between the inside and outside of the cabinet 2, and improving the heat dissipation efficiency in the cabinet 2.

[0048] In this embodiment, in order to further limit the movement of the baffle 31, there are two sliders 33 and two slide bars 34, and the two slide bars 34 are arranged one by one with the two sliders 33. The two sliders 33 are respectively located on opposite sides of the baffle 31 in a direction perpendicular to the movement direction of the baffle 31 (that is, the width direction of the baffle 31, and the movement direction of the baffle 31 is also the length direction of the baffle 31). The two slide bars 34 are respectively located on opposite sides of the baffle 31 in the width direction of the baffle 31. Each slider 33 is connected to the baffle 31, and each slide bar 34 is slidably sleeved outside the corresponding slide bar 34.

[0049] Correspondingly, there are two elastic reset members 35, and the two elastic reset members 35 correspond to the two sliders 33 and the two slide bars 34 one by one. Each elastic reset member 35 is sleeved outside the corresponding slide bar 34, and each elastic reset member 35 is clamped between the corresponding slider 33 and the cabinet 2.

[0050] Exemplarily, the elastic reset member 35 is a telescopic spring. In other examples, the elastic reset member 35 may also be other elastic members, such as a gas spring, a silicone rubber elastic member, etc.

[0051] Optionally, the moisture-proof component 3 also includes an installation frame 36, which is located on the side of the counterweight 32 facing the top of the cabinet 2, and is connected to the cabinet 2. The side of the installation frame 36 facing the bottom of the cabinet 2 has a connecting hole 360 ​​that is opposite to the heat dissipation hole 201.

[0052] The baffle 31 and the slider 33 are both movably located in the installation frame 36, and the slide rod 34 is connected to the installation frame 36. When the baffle 31 is in the second position, the baffle 31 blocks the connecting hole 360. When the baffle 31 is in the first position, the baffle 31 is located on the side of the connecting hole 360 ​​facing the top of the cabinet 2.

[0053] In the above implementation, the installation frame 36 is used to integrate the moisture-proof component 3 into a structure, which is easy to install in the cabinet 2.

[0054] Exemplarily, the mounting frame 36 is a rectangular frame. The mounting frame 36 is embedded in the side wall of the cabinet 2. The mounting frame 36 includes a first connecting plate 361, two side plates 362, a second connecting plate 363, a front plate 364 and a rear plate 365 (combined with Figure 4 ). The two side panels 362 are parallel to each other and are both connected between the first connecting plate 361 and the second connecting plate 363. The front panel 364 and the rear panel 365 are parallel to each other and are respectively connected to the same side of the first connecting plate 361, the two side panels 362, and the second connecting plate 363. The front panel 364 is flush with the outer surface of the side wall of the cabinet 2, and the rear panel 365 is flush with the inner wall surface of the side wall of the cabinet 2. Each of the two side panels 362 has a long strip-shaped mounting groove 3601 on one side facing the other side panel 362. The length direction of the mounting groove 3601 is the length direction of the sliding rod 34. One end of each mounting groove 3601 is in contact with the first connecting plate 361. The other end of each mounting groove 3601 is spaced from the second connecting plate 363. The mounting groove 3601 corresponds to the sliding rod 34 one by one. The sliding rod 34 and the slider 33 connected to the sliding rod 34 are both located in the corresponding mounting groove 3601. The two sliders 33 are both connected to the top of the baffle 31 .

[0055] The connecting hole 360 ​​is located in the orthographic projection of the area of ​​the two side plates 362 where the mounting groove 3601 is not provided on the front plate 364 and the rear plate 365. In this way, when the slider 33 is located in the middle and lower part of the mounting groove 3601, the baffle 31 can block the connecting hole 360 ​​that is directly opposite to the heat dissipation hole 201, thereby blocking the heat dissipation hole 201.

[0056] Figure 4 for Figure 2 The enlarged picture of C in the middle, combined with Figure 4In the disclosed embodiment, in order to facilitate drainage, the second connecting plate 363 has a slope 3602 disposed outwardly on one side facing the first connecting plate 361. The slope 3602 can prevent rainwater from penetrating into the cabinet 2 along the bottom of the mounting frame 36, further improving the waterproof effect.

[0057] Exemplarily, the moisture-proof component 3 also includes a connector 37 , one end of which is located in the mounting frame 36 along the moving direction of the baffle 31 and connected to the baffle 31 , and the other end of the connector 37 is located outside the mounting frame 36 and connected to the counterweight 32 .

[0058] The connecting member 37 is used to connect the baffle 31 and the counterweight 32 together.

[0059] The connecting member 37 is a connecting rope. The rope can be directly tied to the baffle 31 and the counterweight 32 through a lock, etc., for easy connection. Moreover, the rope is generally a fiber member with a light texture, which can reduce the weight of the moisture-proof component 3, and the baffle 31 will not always block the heat dissipation hole 201 due to the rope being too heavy.

[0060] The counterweight 32 is a sponge. The counterweight 32 is attached to the inner wall of the cavity 200. The sponge can quickly absorb water and increase weight, and then drive the baffle 31 to move and block the heat dissipation hole 201 on rainy days.

[0061] In other examples, the weight member 32 may also be other structures, such as cotton or other structural members with good water absorption performance.

[0062] A first filter 203 is fixedly installed outside the heat dissipation hole 201. The first filter 203 can prevent external dust and hair from entering the cabinet 2 through the heat dissipation hole 201 and adhering to the electrical components when the heat dissipation hole 201 is opened, thereby affecting the normal operation of the electrical components.

[0063] See again Figure 2 In the disclosed embodiment, a second filter screen 103 is installed at the water drop hole 10. The second filter screen 103 can prevent dead branches and leaves from entering the cavity 200.

[0064] Optionally, there are two cavities 200 and two heat dissipation holes 201. There are two moisture-proof components 3. The two cavities 200 are respectively located in the opposite side walls of the cabinet 2. For example, the two cavities 200 are respectively located in Figure 1 In the opposite side walls of the cabinet 2 in the left and right directions.

[0065] The two heat dissipation holes 201 are respectively located in the two opposite side walls of the cabinet 2. For example, the two heat dissipation holes 201 are respectively located Figure 1 In the opposite side walls of the cabinet 2 in the left and right directions.

[0066] The two moisture-proof components 3 are respectively located in the cavities 200 in the two opposite side walls of the cabinet 2. For example, the two moisture-proof components 3 are respectively located Figure 1 In the opposite side walls of the cabinet 2 in the left and right directions.

[0067] See also Figure 1 The cabinet 2 is provided with a side wall of the moisture-proof component 3 and a plurality of air holes 20 are also provided, and the inner diameter of the air holes 20 is 0.5-1 mm. The plurality of air holes 20 are connected to the cavity 200 of the side wall. The air holes 20 can accelerate the drying speed of the counterweight 32. In order to prevent the air holes 20 from affecting the installation of the moisture-proof component 3, in the embodiment of the present disclosure, the air holes 20 are arranged near the edge of the side wall. In other examples, the air holes 20 can be arranged at will.

[0068] Optionally, in order to further improve the heat dissipation efficiency inside the cabinet 2, a fan 202 is installed in each heat dissipation hole 201. The fan 202 is located in the heat dissipation hole 201 and is connected to the cabinet 2. The air intake of the fan 202 faces the inside of the cabinet 2, and the air outlet of the fan 202 faces the outside of the cabinet 2. The fan 202 can improve the air circulation efficiency, thereby improving the heat dissipation efficiency.

[0069] Figure 5 for Figure 1 The cross-sectional view along the BB direction, combined with Figure 5 Optionally, the top of the ceiling 1 has a water inlet 100 , and the bottom of the ceiling 1 has a water outlet 101 .

[0070] The electric control cabinet also includes a water storage component 4, which includes a water storage tank 41 and a heat dissipation channel 42. The water storage tank 41 is located outside the cabinet body 2 and is connected to the cabinet body 2. The interior of the water storage tank 41 is connected to the water outlet 101 for storing rainwater flowing into the water inlet 100.

[0071] The heat dissipation channel 42 is partially located in the side wall of the cabinet 2, and the heat dissipation channel 42 is connected to the water storage tank 41. The heat dissipation channel 42 is used to dissipate heat inside the cabinet 2 using water in the water storage tank 41.

[0072] In the above implementation, the water inlet 100 is used to introduce rainwater into the ceiling 1. The water outlet 101 is used to introduce rainwater in the ceiling 1 into the water storage tank 41. The water storage tank 41 is used to store rainwater. The heat dissipation channel 42 is used to introduce rainwater into different parts of the cabinet 2 so that the heat inside the cabinet 2 can be taken away by the rainwater.

[0073] During use, when it rains, the water inlet 100 collects rainwater, and the rainwater flows into the ceiling 1 through the water inlet 100, and flows into the water storage tank 41 through the water outlet 101. When the water storage tank 41 is filled with a certain amount of rainwater, the rainwater flows into the heat dissipation channel 42. Since the heat dissipation channel 42 is partially located in the cabinet 2, the rainwater in the heat dissipation channel 42 absorbs the heat generated by the electronic components inside the cabinet 2, thereby completing the cooling and preventing the internal temperature of the cabinet 2 from being too high, which affects the operation of the electronic components. The rainwater that has absorbed the heat flows into the water storage tank 41 along the heat dissipation channel 42.

[0074] Optionally, the water storage assembly 4 further includes a water pump 43 , which is located in the bottom of the water storage tank 41 and connected to the water storage tank 41 .

[0075] The heat dissipation channel 42 includes a water pipe 421 and a water channel 422. The water pipe 421 is located in the water storage tank 41, and one end of the water pipe 421 is connected to the water pump 43. The water channel 422 is located in the side wall of the cabinet 2, and the water channel 422 is connected to the other end of the water pipe 421 and the water storage tank 41 respectively.

[0076] In the above implementation, the water pump 43 is used to pump rainwater in the water storage tank 41 into the water delivery pipe 421. The water delivery pipe 421 is used to introduce rainwater pumped by the water pump 43 into the water delivery channel 422. The water delivery channel 422 is used to dissipate heat inside the cabinet 2.

[0077] During use, when it rains, the water inlet 100 collects rainwater, and the rainwater enters the ceiling 1 through the water inlet 100, and enters the water storage tank 41 through the water outlet 101. When the water storage tank 41 is filled with a certain amount of rainwater, the water pump 43 starts to work, and the water pump 43 transports the rainwater to the water delivery channel 422 through the water delivery pipe 421, and the rainwater enters the water delivery channel 422. The rainwater in the water delivery channel 422 absorbs the heat generated by the electronic components inside the cabinet 2, thereby completing the cooling and preventing the internal temperature of the cabinet 2 from being too high, affecting the operation of the electronic components. The rainwater that has absorbed the heat then enters the water storage tank 41 along the water delivery channel 422 and the water delivery pipe 421.

[0078] In other examples, the water pump 43 may also be omitted, and in this case, it is sufficient to ensure that the water storage tank 41 is located above the water delivery channel 422. Rainwater in the water storage tank 41 automatically flows into the water delivery channel 422 at a lower position, and the interior of the cabinet 2 can be cooled.

[0079] Figure 6 for Figure 5 The enlarged picture at D in the middle, combined with Figure 6Optionally, the water supply channel 422 includes a water inlet section 4221 and multiple water supply sections 4222, the water inlet section 4221 is located in the first side wall of the cabinet 2, and the water inlet section 4221 is connected to the other end of the water supply pipe 421, and the length direction of the water inlet section 4221 is perpendicular to the length direction of the cabinet 2.

[0080] Combination Figure 2 , multiple water delivery sections 4222 are arranged at intervals along the length direction of the water inlet section 4221, and each of the multiple water delivery sections 4222 is located in the first side wall, the second side wall and the third side wall which are connected in sequence, and the length direction of the water delivery section 4222 located in the second side wall or the third side wall is the same as the length direction of the cabinet 2, and the water delivery sections 4222 are respectively connected to the water inlet section 4221 and the water storage tank 41.

[0081] In this way, the water delivery channel 422 can occupy a larger area in the cabinet 2 through the water delivery section 4222 and the water inlet section 4221, so that the water delivery channel 422 can be distributed in various parts of the cabinet 2 as much as possible, thereby improving the heat dissipation efficiency.

[0082] In the above arrangement, the water inlet section 4221 is located at the top of the cabinet 2, and the water delivery section 4222 is located at two opposite side walls connected to the top. The water delivery section 4222 is distributed in the cabinet 2 in a U-shaped structure, so that all directions of the cabinet 2 can be cooled.

[0083] In other examples, the arrangement of the water delivery channel 422 may also be other structures, for example, a channel is provided in each side wall of the cabinet 2 .

[0084] Combination Figure 5 Optionally, the water storage component 4 also includes a heat sink 44 , which is located outside the water storage tank 41 and connected to the outer wall of the water storage tank 41 .

[0085] In the above implementation, a heat sink 44 is fixedly installed on the outer surface of the water tank 41 , and the heat sink 44 dissipates heat and cools the rainwater inside the water tank 41 , thereby reducing the temperature of the rainwater and improving the heat absorption efficiency when the rainwater flows in the water conveyance channel 422 .

[0086] In order to further confirm the water level in the water storage tank 41 , a liquid level sensor is connected to the inner wall of the water storage tank 41 .

[0087] Optionally, the ceiling 1 includes a pyramid top 11 and a bottom plate 12, the pyramid top 11 includes four triangular slanted side plates 111, and the top angles of the four slanted side plates 111 constitute the top of the pyramid top 11, the bottom plate 12 is located at the bottom of the four slanted side plates 111, and are all connected to the four slanted side plates 111, and the bottom plate 12 and the four slanted side plates 111 define a water inlet cavity 102 for storing water.

[0088] The water inlet 100 is located at the top of the pyramid top 11, and is located on the side wall of the bottom plate 12 facing the water storage tank 41. The water outlet 101 and the water drop hole 10 are both located at the bottom of the pyramid top 11, and the water inlet 100 and the water outlet 101 are both connected to the water inlet cavity 102. The water drop hole 10 is spaced from the water inlet cavity 102.

[0089] In the above implementation, the pyramid top 11 can accelerate the flow of rainwater through the triangular shaped inclined side plates 111 to prevent rainwater from accumulating on the pyramid top 11. The bottom plate 12 is used to form a sealed cavity with the pyramid top 11 so that rainwater can enter the pyramid top 11.

[0090] In this embodiment, the bottom plate 12 has a water collecting trough 120, and the opening of the water collecting trough 120 faces the pyramid top 11. The water collecting trough 120 is connected to the water inlet cavity 102. The water collecting trough 120 is used to accumulate water. The water outlet 101 is located on one side of the water collecting trough 120 and is connected to the water collecting trough 120.

[0091] A pyramid-shaped filter frame 13 is fixedly installed in the water inlet 100. The filter frame 13 is used to filter impurities in rainwater. In addition, when it rains, the filter frame 13 can also be washed by rainwater, and dead branches and leaves will fall to the ground along the inclined surface, preventing dead branches and leaves from covering the filter frame 13 and affecting the collection of rainwater in the water inlet 100.

[0092] Optionally, the electric control cabinet further comprises a cabinet door 5, and the cabinet door 5 and the water storage tank 41 are respectively located on opposite sides of the cabinet body 2. One side of the cabinet door 5 is rotatably connected to the cabinet body 2 through a hinge.

[0093] The electric control cabinet can be opened through the cabinet door 5 to facilitate inspection or maintenance of the internal electrical components.

[0094] The following briefly introduces the working process of the electric control cabinet provided by the embodiment of the present disclosure:

[0095] When it rains, rainwater flows into the cavity 200 along the drain hole 10 and falls onto the counterweight 32. After the counterweight 32 absorbs the rainwater, its weight gradually increases. The counterweight 32 drives the baffle 31 to move downward through the connecting member 37. The downward movement of the baffle 31 drives the slider 33 to move downward to squeeze the elastic reset member 35. The baffle 31 switches from the first position to the second position. The baffle 31 closes the heat dissipation hole 201 to prevent external water vapor from entering the cabinet 2 and causing adverse effects on the electronic components inside the cabinet 2.

[0096] At the same time, the water inlet 100 collects rainwater, and the rainwater enters the ceiling 1 through the water inlet 100, and enters the water storage tank 41 through the water outlet 101. When the water storage tank 41 is filled with a certain amount of rainwater, the water pump 43 starts to work, and the water pump 43 transports the rainwater to the water delivery channel 422 through the water delivery pipe 421, and the rainwater enters the water delivery channel 422. The rainwater in the water delivery channel 422 absorbs the heat generated by the electronic components inside the cabinet 2, thereby completing the cooling and preventing the internal temperature of the cabinet 2 from being too high, affecting the operation of the electronic components. The rainwater that has absorbed the heat then enters the water storage tank 41 along the water delivery channel 422 and the water delivery pipe 421.

[0097] When the rain stops, the counterweight 32 gradually dries up, the weight of the counterweight 32 gradually decreases, and the slider 33 moves upward under the elastic force of the elastic reset member 35. When the elastic force provided by the elastic reset member 35 is greater than the weight of the counterweight 32, the slider 33 drives the baffle 31 to move upward, and the baffle 31 switches from the second position to the first position, thereby opening the heat dissipation hole 201, facilitating air exchange between the inside and outside of the cabinet 2, and improving the heat dissipation efficiency in the cabinet 2.

[0098] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
