Description

Technical Field

[0001] The present invention relates to the technical field of electric control cabinets, and in particular to an outdoor waterproof electric control cabinet. Background Art

[0002] The electric control cabinet is a control cabinet box that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. Its layout should meet the requirements of normal operation of the power system, facilitate maintenance, and not endanger the safety of people and surrounding equipment. The electric control cabinet is one of the most important equipment in production equipment, and the safe and normal operation of the equipment is a necessary guarantee for production. Electric control cabinets are also often used outdoors. However, most of the existing outdoor electric control cabinets do not have a waterproof function. When rainwater enters the electric control cabinet, it will not only corrode the electrical appliances inside the electric control cabinet and cause the internal circuit to short-circuit, but in severe cases, it will also cause a fire inside the electric control cabinet. In addition, some electric control cabinets will be equipped with protective covers, which will affect the heat dissipation of the entire cabinet, resulting in excessive internal temperature and accidents.

[0003] After searching, the existing patent (Announcement No.: CN115621854A) discloses an outdoor waterproof electric control cabinet, which includes a cabinet, a fixing column is provided on the top of the cabinet, rain shields are provided on both sides of the top of the fixing column, a temperature sensor is provided on the top of the cabinet, a duct is provided on one side of the cabinet, a cooling fan connected to the duct is provided on one side of the cabinet, a door is provided on one side of the cabinet, a sealing structure is provided between the door and the cabinet, a bottom plate is provided under the cabinet, and a shock absorbing structure is provided between the bottom plate and the cabinet. Compared with the prior art, the advantages of this invention are: it can not only effectively waterproof and prevent rainwater from entering the cabinet to corrode components, but also dissipate heat inside to avoid accidents caused by excessive internal temperature, and effectively reduce shock to the cabinet during transfer, transportation, and bumps to further protect internal components.

[0004] However, there are still some shortcomings in the above scheme. It has good sealing performance and can effectively prevent water, but it only dissipates heat inside the cabinet through the air duct 7 and a cooling fan 8, and the fluidity is poor, resulting in low ventilation and heat dissipation efficiency. In addition, in the hot summer, when the outside is at high temperature, the cooling fan 8 continuously circulates the hot air flow, and the heat dissipation performance that can be achieved is greatly reduced.

[0005] In addition, after searching, the existing patent (publication number: CN114079240A) discloses an outdoor waterproof electric control cabinet. The triangular waterproof cover of the invention can improve the smoothness of drainage on rainy days, and the waterproof sealing strip and waterproof gland improve the dustproof level and sealing inside the electric control cabinet, thereby improving the safety of the electric control cabinet.

[0006] However, the above solution has a similar problem to the existing patent (Announcement No.: CN115621854A), that is, while having good waterproof performance, it is difficult to provide good heat dissipation performance inside the cabinet.

[0024] The working principle and beneficial effects of the present invention are:

[0025] In the present invention, ventilation nets are arranged on the upper sides of the left and right ends of the electric control cabinet body, and a ventilation and dust removal mechanism is arranged inside the top of the electric control cabinet body, wherein the ventilation and dust removal mechanism includes two cleaning components symmetrically arranged inside the electric control cabinet body, and a blowing component is arranged between the two cleaning components. When working, only one motor can simultaneously drive multiple fans to operate at different positions on the top of the cabinet body, which saves costs and greatly improves the heat dissipation efficiency inside the cabinet body. Under the action of the airflow partition frame, the fan blows air downward from the top of the electric control cabinet body through the through slots provided on the airflow partition frame. When the wind reaches the bottom of the electric control cabinet body, it starts to flow upward and is discharged through the ventilation nets provided on the upper sides of the left and right ends of the electric control cabinet body, thereby realizing the circulation of air inside the cabinet body and further improving the heat dissipation efficiency.

[0026] In the present invention, a transmission component is arranged at the lower side of the blowing component, and the transmission component can synchronously drive the two cleaning components under the transmission cooperation with the blowing component, so that while ventilation and heat dissipation are being performed, the cleaning brush on the cleaning component can slowly reciprocate up and down to perform friction cleaning on the ventilation net, and in combination with the wind blown out from the ventilation net, the dust being cleaned can be blown away from the main body of the electric control cabinet;

[0027] In the present invention, a water containing mechanism is provided at the bottom of the main body of the electric control cabinet, and the water containing mechanism includes a water accumulation frame for collecting rainwater. An air collecting box is fixedly installed on the top of the main body of the electric control cabinet by bolts, and a plurality of connecting holes are evenly provided on the top of the main body of the electric control cabinet for connecting the air collecting box with the interior of the main body of the electric control cabinet. An air transmission mechanism is provided between the air collecting box and the water accumulation frame, and the double-layer serpentine coil on the air transmission mechanism is located inside the water accumulation frame, so that the rainwater collected inside the water accumulation frame can soak the double-layer serpentine coil, thereby cooling the air passing through the double-layer serpentine coil, and thus greatly improving the heat dissipation efficiency inside the main body of the electric control cabinet. In addition, when the rainwater inside the water accumulation frame evaporates at high temperature, it can also take away the local heat outside the main body of the electric control cabinet, and has good practical performance;

[0028] In the present invention, on rainy days, rainwater can flow well to the inside of the water accumulation frame through the rainproof mechanism and the guide of the drainage plate for collection, and when the water level inside the water accumulation frame rises to the water outlet, the rainwater will flow out to the outside of the water accumulation frame through the water outlet, that is, the water level of the rainwater inside the water accumulation frame does not exceed the water outlet, so as to avoid soaking the bottom of the cabinet. Among them, the water outlet can also be replaced by a strip groove during actual use, so that the debris floating on the water surface can flow out to the outside of the water accumulation frame through the strip groove. When rainwater gathers inside the water accumulation frame, the dust and debris in the water will gradually sink to the bottom of the water accumulation frame under the action of gravity, and because the bottom of the water accumulation frame is provided with a V-shaped bottom surface, as the debris continues to accumulate, it will gradually slide toward the inside of the dirt collection box. At this time, the dirt collection box can be manually pulled out from the inside of the water accumulation frame to clean the collected dirt, which is simple to operate and convenient to use.

DETAILED DESCRIPTION

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5A waterproof outdoor electric control cabinet comprises: an electric control cabinet body 2 for installing an electric component mounting frame 7, the electric component mounting frame 7 is used to install electric components for the electric control cabinet such as circuit breakers, conventional relays, and integrated relay protection devices, a water collecting mechanism 1 is arranged at the bottom of the electric control cabinet body 2, the water collecting mechanism 1 comprises a water accumulation frame 11 for collecting rainwater, an air collecting box 3 is fixedly installed on the top of the electric control cabinet body 2 by bolts, and a plurality of connecting holes 25 are evenly opened on the top of the electric control cabinet body 2 for connecting the air collecting box 3 with the inside of the electric control cabinet body 2.

[0042] Furthermore, a rainproof mechanism 5 is provided above the electric control cabinet body 2 , and the rainproof mechanism 5 includes a rainproof cover 52 . Two support plates 51 for supporting the rainproof cover 52 are fixedly connected between the rainproof cover 52 and the gas collecting box 3 .

[0043] Furthermore, the water storage mechanism 1 includes a water accumulation frame 11 with a water accumulation cavity formed inside, a foot 12 is symmetrically fixed at the bottom of the water accumulation frame 11, a drainage plate 16 is symmetrically fixed on both sides of the top of the water accumulation frame 11, a water outlet 15 is formed at the junction of the drainage plate 16 and the water accumulation frame 11, a V-shaped bottom surface 14 is formed at the bottom of the water accumulation cavity, a plug-in cavity 17 is formed at the bottom of the V-shaped bottom surface 14, a dirt collection box 13 is slidably sleeved inside the plug-in cavity 17, and one end of the dirt collection box 13 slides through the side wall of the water accumulation frame 11. A cabinet door 21 is connected to the front side of the electric control cabinet body 2, and column legs 23 are fixed at the bottom ends of the four corners of the electric control cabinet body 2, and the column legs 23 are fixed to the bottom of the water accumulation frame 11 by bolts.

[0044] Working principle of this embodiment: install the electrical component mounting frame 7 with electrical components such as circuit breakers, conventional relays, and integrated relay protection devices inside the electrical control cabinet body 2. When it rains, rainwater flows through the rain cover 52 and the guide plate 16 to the inside of the water accumulation frame 11 for collection. When the water level inside the water accumulation frame 11 rises to the water outlet 15, the rainwater will flow out through the water outlet 15 to the outside of the water accumulation frame 11, that is, the water level of the rainwater inside the water accumulation frame 11 does not exceed the water outlet 15. It should be noted that the water outlet 15 can also be replaced by a strip groove, so that debris floating on the water surface can flow out to the outside of the water accumulation frame 11 through the strip groove. When rainwater gathers inside the water collection frame 11, the dust and debris in the water will gradually sink to the bottom of the water collection frame 11 under the action of gravity. Since a V-shaped bottom surface 14 is provided at the bottom of the water collection frame 11, as the debris continues to accumulate, it will gradually slide toward the inside of the dirt collection box 13. At this time, the dirt collection box 13 can be manually pulled out from the water collection frame 11 to clean the collected dirt. Example

[0045] See also Figure 1 , Figure 2 , Figure 4 as well as Figure 5A gas delivery mechanism 4 is provided between the gas collecting box 3 and the water accumulation frame 11. Ventilation nets 24 are provided on the upper sides of both ends of the electric control cabinet body 2. A rainproof frame 22 with an opening facing downward is fixedly connected to the side wall of the electric control cabinet body 2 outside the ventilation net 24 to protect the ventilation net 24 from rain.

[0046] Furthermore, the gas transmission mechanism 4 includes a double-layer serpentine coil 41 installed on the inner side of the water accumulation frame 11, and the upper side wall of the double-layer serpentine coil 41 is fixedly connected to a plurality of U-shaped exhaust pipes 43, and the other end of the U-shaped exhaust pipe 43 is fixedly connected to the gas collecting box 3, and a thermal insulation sleeve 42 is sleeved on the outer wall of the U-shaped exhaust pipe 43. The gas transmission mechanism 4 also includes a plurality of right-angle air intake pipes 44 fixedly connected to the lower side wall of the double-layer serpentine coil 41, and the right-angle air intake pipes 44 penetrate the side wall of the water accumulation frame 11 and are fixedly connected thereto.

[0047] Working principle of this embodiment: Since the double-layer serpentine coil 41 is located inside the water accumulation frame 11, the rainwater collected inside the water accumulation frame 11 can soak the double-layer serpentine coil 41. In hot summer, the outside air has high heat. When the hot air is directly pumped into the electric control cabinet body 2, the heat dissipation efficiency inside the electric control cabinet body 2 will be greatly reduced. Since the double-layer serpentine coil 41 is soaked by the collected rainwater, and the electric control cabinet body 2 can shade the rainwater inside the water accumulation frame 11, so that the rainwater temperature is relatively low, therefore, the air passing through the double-layer serpentine coil 41 can absorb heat from the rainwater, thereby greatly improving the heat dissipation efficiency inside the electric control cabinet body 2. In addition, when the rainwater inside the water accumulation frame 11 evaporates at high temperature, it can also take away the heat outside the electric control cabinet body 2. Moreover, even if the inside of the water accumulation frame 11 is in a dry state, since the electric control cabinet body 2 can provide shade for the inside of the water accumulation frame 11, the air passing through the double-layer serpentine coil 41 can also be cooled to a certain extent. Example

[0048] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 as well as Fig. 9 A ventilation and dust removal mechanism 6 is provided inside the top of the electric control cabinet body 2. The ventilation and dust removal mechanism 6 includes two cleaning components 63 symmetrically provided inside the electric control cabinet body 2, which are used to clean the ventilation net 24. A blowing component 61 is provided between the two cleaning components 63. A motor 8 for driving the blowing component 61 is installed at the top of the air collecting box 3, so that the blowing component 61 can suck the inside of the air collecting box 3 through the connecting hole 25. A transmission component 62 is provided at the lower side of the blowing component 61. The transmission component 62 can synchronously drive the two cleaning components 63 in cooperation with the transmission of the blowing component 61.

[0049] Specifically, the blowing component 61 includes four first pulleys 611 rotatably connected to the four corners of the top of the electric control cabinet body 2, and a second pulley 613 and a third pulley 614 are rotatably connected to the middle position of the top of the electric control cabinet body 2. The output shaft of the motor 8 rotates through the top of the air collecting box 3 and the electric control cabinet body 2 and is fixedly connected to the third pulley 614. A transmission belt 615 is provided for a common transmission sleeve between the second pulley 613, the third pulley 614 and the four first pulleys 611, and a fan 612 is provided at the bottom of the third pulley 614 and the four first pulleys 611.

[0051] Among them, the second linkage assembly 622 includes a coupling 6224 fixedly connected to the bottom end of the second pulley 613 and a large gear 6226 rotatably connected to the bottom end of the suspension rod 623, a small gear 6225 is fixedly connected to the bottom end of the coupling 6224, the small gear 6225 is meshed with the large gear 6226, a fixed ring 6221 is fixedly connected to the end of the fixed rod 624 away from the inner wall of the electric control cabinet body 2, a gear ring 6223 is rotatably sleeved on the inner side of the fixed ring 6221, the gear ring 6223 is meshed with the large gear 6226, and a cross hanger 6222 is fixedly connected to the bottom end of the gear ring 6223.

[0052] Among them, the first linkage component 621 includes a second small pulley 6212 that is rotatably connected to the bottom end of the center of the cross hanger 6222 through an axis rod, a third small pulley 6213 is fixed to the bottom end of the second small pulley 6212, a first small pulley 6211 is arranged on one side of the second small pulley 6212, and a fourth small pulley 6214 is arranged on one side of the third small pulley 6213, a first linkage belt 6215 is connected for transmission between the second small pulley 6212 and the first small pulley 6211, and a second linkage belt 6216 is connected for transmission between the fourth small pulley 6214 and the third small pulley 6213.

[0053] Specifically, the cleaning component 63 includes a reciprocating screw 631 rotatably connected to the top of the electric control cabinet body 2, a limiting rod 632 fixedly connected to the top of the electric control cabinet body 2 is arranged on one side of the reciprocating screw 631, a slider 633 matching the reciprocating screw 631 is sleeved on the outer side of the reciprocating screw 631, the limiting rod 632 passes through the interior of the slider 633 and is slidably connected thereto, a cleaning brush 634 is connected to the outer wall of the slider 633, and the bottom ends of the two reciprocating screws 631 are fixedly sleeved inside the fourth small pulley 6214 and the first small pulley 6211, respectively. During the rotation of the second pulley 613, the coupling 6224 can be driven to rotate, the coupling 6224 drives the small gear 6225 to rotate, the small gear 6225 drives the large gear 6226 to rotate, and the rotation rate of the large gear 6226 is lower than that of the small gear 6225. When the large gear 6226 rotates, the gear ring 6223 can be driven to rotate inside the fixed ring 6221, and the rotation rate of the gear ring 6223 is much lower than that of the second pulley 613. When the gear ring 6223 rotates, the second small pulley 6212 and the third small pulley 6213 can be driven to rotate through the cross hanger 6222. Under the action of the second linkage belt 6216 and the first linkage belt 6215, the fourth small pulley 6214 can be driven It rotates with the first small pulley 6211, and can drive the two reciprocating screws 631 to rotate slowly through the fourth small pulley 6214 and the first small pulley 6211.

It is a form of three-dimensional cam pair, which is manifested by two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve. Through the rotation of the screw, the side of the spiral groove pushes the slider placed in the spiral groove to make axial reciprocating motion. This is a prior art and will not be elaborated here).

[0054] Furthermore, an airflow partition frame 9 is fixedly connected to the top of the electric control cabinet body 2, and a through groove 91 of different sizes is opened through the bottom of the airflow partition frame 9. The airflow partition frame 9 is located on the upper side of the second linkage belt 6216 and the first linkage belt 6215, and the blowing component 61 is located on the inner side of the airflow partition frame 9. The airflow partition frame 9 is located between the two cleaning components 63, and the shaft at the top of the second small pulley 6212 rotates and passes through the interior of the airflow partition frame 9.

[0055] Working principle of this embodiment: when it is necessary to ventilate and dissipate heat inside the electric control cabinet body 2 after a long period of work, start the motor 8, and the motor 8 drives the third pulley 614 to rotate through its output shaft. Under the action of the transmission belt 615, the second pulley 613 rotates synchronously with the four first pulleys 611. When the third pulley 614 and the four first pulleys 611 rotate, they can drive the fan 612 to rotate. The fan 612 blows air downward from the top of the electric control cabinet body 2 through the through groove 91 opened on the airflow partition frame 9. When the wind reaches the bottom of the electric control cabinet body 2, it starts to flow upward and is discharged through the ventilation net 24 opened on the upper sides of the left and right ends of the electric control cabinet body 2 to achieve ventilation and heat dissipation.

[0056] The working principle and use process of the present invention are as follows: an electrical component mounting frame 7 equipped with electrical components such as circuit breakers, conventional relays, and integrated relay protection devices is installed inside the electrical control cabinet body 2. When it rains, rainwater flows through the rainproof mechanism 5 and the guide plate 16 to the inside of the water accumulation frame 11 for collection. When the water level inside the water accumulation frame 11 rises to the water outlet 15, the rainwater will flow out through the water outlet 15 to the outside of the water accumulation frame 11, that is, the water level of the rainwater inside the water accumulation frame 11 does not exceed the water outlet 15, so as to avoid soaking the bottom of the cabinet. It should be noted that the water outlet 15 can also be replaced by a strip groove, so that debris floating on the water surface can flow out to the outside of the water accumulation frame 11 through the strip groove. When rainwater gathers inside the water collection frame 11, the dust and debris in the water will gradually sink to the bottom of the water collection frame 11 under the action of gravity. Since a V-shaped bottom surface 14 is provided at the bottom of the water collection frame 11, as the debris continues to accumulate, it will gradually slide toward the inside of the dirt collection box 13. At this time, the dirt collection box 13 can be manually pulled out from the water collection frame 11 to clean the collected dirt.

[0057] When it is necessary to ventilate and dissipate heat inside the electric control cabinet body 2 after a long period of work, start the motor 8, and the motor 8 drives the third pulley 614 to rotate through its output shaft. Under the action of the transmission belt 615, the second pulley 613 rotates synchronously with the four first pulleys 611. When the third pulley 614 and the four first pulleys 611 rotate, they can drive the fan 612 to rotate. The fan 612 blows air downward from the top of the electric control cabinet body 2 through the through groove 91 opened on the airflow partition frame 9. When the wind reaches the bottom of the electric control cabinet body 2, it starts to flow upward and is discharged through the ventilation net 24 opened on the upper sides of the left and right ends of the electric control cabinet body 2 to achieve ventilation and heat dissipation. During the rotation of the multiple fans 612, the inside of the air collecting box 3 can be sucked through the connecting hole 25, so that the internal pressure of the air collecting box 3 is reduced. The air collecting box 3 sucks the upper layer of the double-layer serpentine coil 41 through the U-shaped exhaust pipe 43, and the upper layer of the double-layer serpentine coil 41 sucks the lower layer of the double-layer serpentine coil 41, and the lower layer of the double-layer serpentine coil 41 sucks the right-angle suction pipe 44. The right-angle suction pipe 44 sucks the external air of the electric control cabinet body 2 into the electric control cabinet body 2. It should be noted that the port of the right-angle suction pipe 44 located outside the water accumulation frame 11 faces downward, and a filter net can be set at the port to filter the air entering the water accumulation frame 11. Since the double-layer serpentine coil 41 is located inside the water accumulation frame 11, the rainwater collected inside the water accumulation frame 11 can soak the double-layer serpentine coil 41. In the hot summer, the outside air has a large amount of heat. When the hot air is directly pumped into the electric control cabinet body 2, the heat dissipation efficiency inside the electric control cabinet body 2 will be greatly reduced. Since the double-layer serpentine coil 41 is soaked by the collected rainwater, and the electric control cabinet body 2 can shade the rainwater inside the water accumulation frame 11, so that the rainwater temperature is relatively low, the air passing through the double-layer serpentine coil 41 can absorb heat from the rainwater, thereby greatly improving the heat dissipation efficiency inside the electric control cabinet body 2. In addition, when the rainwater inside the water accumulation frame 11 evaporates at high temperature, it can also take away the heat outside the electric control cabinet body 2. Moreover, even if the inside of the water accumulation frame 11 is in a dry state, since the electric control cabinet body 2 can shade the inside of the water accumulation frame 11, the air passing through the double-layer serpentine coil 41 can also be cooled to a certain extent.

[0058] In addition, during the rotation of the second pulley 613, the coupling 6224 can be driven to rotate, the coupling 6224 drives the small gear 6225 to rotate, the small gear 6225 drives the large gear 6226 to rotate, and the rotation rate of the large gear 6226 is lower than that of the small gear 6225. When the large gear 6226 rotates, the gear ring 6223 can be driven to rotate inside the fixed loop 6221, and the rotation rate of the gear ring 6223 is much lower than that of the second pulley 613. When the gear ring 6223 rotates, the second small pulley 6212 and the third small pulley 6213 can be driven to rotate through the cross hanger 6222. Under the action of 215, the fourth small pulley 6214 and the first small pulley 6211 can be driven to rotate, and the four small pulleys 6214 and the first small pulley 6211 can drive the two reciprocating screws 631 to rotate slowly. When the reciprocating screw 631 rotates, it can drive the slider 633 to move back and forth along the outer wall of the reciprocating screw 631, thereby driving the cleaning brush 634 to move back and forth up and down to frictionally clean the ventilation net 24. The setting of the airflow partition frame 9 enables the air to start flowing upward when it reaches the bottom of the electric control cabinet body 2, and be discharged through the ventilation net 24 opened on the upper sides of the left and right ends of the electric control cabinet body 2, thereby being able to blow the cleaned dust away from the electric control cabinet body 2.

[0059] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
