Description

Technical Field

[0001] This utility model relates to the field of mobile crushing plants, and in particular to an electrical control cabinet for mobile crushing plants. Background Technology

[0002] A mobile crushing plant is a mobile rock crushing equipment that integrates crushing and screening functions. It is mainly used in mining, construction, highway, railway and water conservancy projects. With a vehicle-mounted unit as its core, it integrates a crusher, vibrating screen, feeder and belt conveyor. The integrated design reduces on-site installation steps and improves operational efficiency.

[0003] The electrical control cabinet of a mobile crushing plant is mounted on the vehicle body and moves with it during operation. Mobile crushing plants generate a large amount of dust during production. If the electrical control cabinet is not properly sealed, external dust will enter, affecting the lifespan of electrical components. Conversely, if the cabinet is too tightly sealed, it will hinder the heat dissipation of high-power components inside. Therefore, existing electrical control cabinets cannot simultaneously meet the requirements of dust prevention and heat dissipation. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide an electrical control cabinet for a mobile crushing plant that overcomes or at least partially solves the above problems, so that the electrical control cabinet has good dustproof and heat dissipation effects.

[0005] Specifically, this utility model provides an electrical control cabinet for a mobile crushing plant, comprising: The cabinet contains electrical components, and an air inlet is provided on the side wall of the cabinet. A rainproof cover is installed on the top of the cabinet, and an air outlet is formed inside the rainproof cover; the air outlet communicates with the interior of the cabinet at its bottom; the front end of the rainproof cover extends beyond the cabinet, and an air outlet is provided at the bottom of the front end of the rainproof cover; An air intake fan is installed at the air inlet to supply air into the cabinet. An exhaust fan is installed at the connection between the cabinet and the rainproof cover to send the gas inside the cabinet into the air outlet so that the gas is discharged from the air outlet.

[0006] Optionally, the air inlet is located at the lower part of the side wall of the cabinet.

[0007] Optionally, the air outlet is a long strip extending in the front-to-back direction; There are multiple air outlets, which are evenly distributed along the horizontal direction of the electrical control cabinet.

[0008] Optionally, the bottom wall of the cabinet is provided with a cable inlet and outlet, and the cable inlet and outlet are provided with a waterproof connector.

[0009] Optionally, the cabinet includes a housing with a front opening and a door rotatably disposed at the front opening to open and close the front opening; The inner wall of the door is equipped with a sealing strip.

[0010] Optionally, the inner wall of the door is provided with reinforcing ribs, and the inner wall of the shell is provided with reinforcing rib plates.

[0011] Optionally, the cabinet has a mounting bracket located below the air inlet on the outer side wall for mounting the air intake fan.

[0012] Optionally, the cabinet has a baffle plate located above the air intake fan on the outer side wall.

[0013] Optionally, the intake fan is a centrifugal fan; the exhaust fan is an axial flow fan.

[0014] Optionally, mounting brackets are provided on the outer sides of both side walls of the cabinet; the mounting brackets include a vertical plate fixed to the cabinet, a horizontal plate perpendicular to the bottom end of the vertical plate, and a connecting rib plate connecting the vertical plate and the horizontal plate; the horizontal plate has mounting holes.

[0015] In the electrical control cabinet of this utility model for a mobile crushing plant, an intake fan supplies air into the cabinet, making the air pressure inside the cabinet higher than the external air pressure. Therefore, dust from outside the cabinet cannot enter, achieving the purpose of dust prevention. Moreover, through the cooperation of the intake and exhaust fans, the external airflow passes through the air inlet sequentially, exchanges heat with the electrical components, enters the air outlet, and finally exits from the air outlet. This heat exchange process dissipates the heat generated by the electrical components, thereby facilitating heat dissipation inside the electrical control cabinet.

[0022] Figure 1 This is a schematic structural diagram of the electrical control cabinet 10 for a mobile crushing plant according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figure 2 and Figure 3 This utility model provides an electrical control cabinet 10 for a mobile crushing plant, including a cabinet body 110, a rainproof cover 120, an air inlet fan, and an exhaust fan. The cabinet body 110 houses electrical components, and an air inlet 113 is provided on the side wall of the cabinet body 110. The rainproof cover 120 is located at the top of the cabinet body 110, and an air outlet cavity is formed within the rainproof cover 120. The air outlet cavity communicates with the interior of the cabinet body 110 at its bottom. The front end of the rainproof cover 120 extends beyond the cabinet body 110, and an air outlet 121 is provided at the bottom of the front end of the rainproof cover 120. The air inlet fan is located at the air inlet 113 and is used to supply air into the cabinet body 110. The exhaust fan is located at the connection between the cabinet body 110 and the rainproof cover 120 and is used to send the gas inside the cabinet body 110 into the air outlet cavity so that the gas is discharged from the air outlet 121.

[0023] In the electrical control cabinet 10 for a mobile crushing plant of this invention, external airflow enters the cabinet 110 under the suction of the intake fan. The airflow exchanges heat with the electrical components inside the cabinet 110, forming hot air. The exhaust fan draws the hot air from the cabinet 110 into the exhaust chamber and discharges it outward through the exhaust port 121. Because the intake fan supplies air into the cabinet 110, the air pressure inside the cabinet 110 is greater than the external air pressure, i.e., the inside of the cabinet 110 is under positive pressure. Therefore, dust from outside the electrical control cabinet 10 is less likely to enter the cabinet 110, achieving the purpose of dust prevention. Moreover, through the cooperation of the intake and exhaust fans, the external airflow passes sequentially through the air inlet 113, exchanges heat with the electrical components, enters the exhaust chamber, and finally exits from the exhaust port 121, dissipating the heat generated by the electrical components and thus facilitating heat dissipation inside the electrical control cabinet 10. Therefore, the electrical control cabinet 10 for a mobile crushing plant of this invention can simultaneously achieve good heat dissipation and dust prevention effects.

[0024] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the air inlet 113 is located on the lower part of the side wall of the cabinet 110.

[0025] In this embodiment, as Figure 1 In the airflow diagram, external airflow enters the bottom of cabinet 110 through air inlet 113, then flows upward and exchanges heat with electrical components. The hot air rises into the air outlet cavity and is finally discharged through air outlet 121. Because the airflow flows from bottom to top, it easily fills the interior of cabinet 110, providing not only good positive pressure dust prevention but also sufficient heat exchange for electrical components, facilitating heat removal and improving the heat dissipation of the electrical cabinet.

[0026] In some embodiments of this utility model, such as Figure 2 As shown, the air outlet 121 is a long strip extending in the front-to-back direction. There are multiple air outlets 121, evenly distributed laterally along the electrical control cabinet 10. In this embodiment, the lateral direction refers to the left-to-right direction. The presence of multiple evenly distributed air outlets 121 facilitates the rapid and uniform discharge of airflow from the air outlet cavity. Of course, the shape of the air outlet 121 can also be square or circular, etc.

[0027] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, a cable inlet / outlet 114 is provided on the bottom wall of the cabinet 110, and a waterproof connector is provided at the cable inlet / outlet 114.

[0028] In this embodiment, the use of waterproof connectors ensures a good seal at the cable inlet / outlet 114, providing both waterproofing and dustproofing. For example, a waterproof connector with an IP68 protection rating can be used. In this embodiment, since the cabinet 110 contains cables of different specifications, the cable inlet / outlet 114 has different diameters, thus requiring waterproof connectors with varying diameters to meet the requirements of different cable inlets / outlets 114.

[0029] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the cabinet 110 includes a housing 111 with a front opening and a door 112 rotatably disposed at the front opening to open and close the front opening. A sealing strip is provided on the inner wall of the door 112.

[0030] In this embodiment, the sealing strip can seal the opening and closing points of the door 112 and the housing 111, thereby achieving a good dustproof effect.

[0031] In some embodiments of this utility model, the sealing strip is formed by spraying molten hot melt adhesive onto the inner wall of the door body 112 using a spraying device. The sealing strip formed in this way has a stronger connection with the door body 112, a better sealing effect, and is also easier to control the shape of the sealing strip.

[0032] In some alternative embodiments, existing molded sealing strips can be directly adhered to the inner wall of the door 112, making installation simpler.

[0033] In some embodiments of this utility model, such as Figure 3 As shown, the inner wall of the door body 112 is provided with reinforcing ribs 115, and the inner wall of the shell 111 is provided with reinforcing rib plates 116.

[0034] In this embodiment, since the door 112 is provided with reinforcing ribs 115 and the shell 111 is provided with reinforcing ribs 116, the door 112 and the shell 111 are stronger, which in turn makes the cabinet 110 stronger, enhances the durability of the electrical control cabinet 10, and extends the service life of the electrical control cabinet 10.

[0035] In some embodiments of this utility model, the door 112 is also provided with a handle to facilitate opening and closing of the door 112. The door 112 is also provided with a door lock to facilitate locking the door 112 and the housing 111 together.

[0036] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a mounting support plate 117 is provided on the outer side wall of the cabinet 110, located below the air inlet 113, for installing the air intake fan. The exhaust port of the air intake fan is connected to the air inlet 113 on the side wall of the cabinet 110. The mounting support plate 117 includes a vertical connecting plate and a horizontal support plate perpendicular to the lower end of the vertical connecting plate. The horizontal support plate has mounting holes 1184 for installing the air intake fan. In this embodiment, the air intake fan is installed on the outer side wall of the cabinet 110 via the mounting support plate 117, which facilitates the installation and removal of the air intake fan and does not occupy the internal space of the cabinet 110.

[0037] In some embodiments of this utility model, a baffle plate is provided on the side wall of the cabinet 110 above the air intake fan. In this embodiment, the baffle plate can protect the air intake fan from rain and also has a certain dustproof function, thereby protecting the air intake fan and extending its service life.

[0038] In some embodiments of this invention, the intake fan is a centrifugal fan. A centrifugal fan is a device that uses a high-speed rotating impeller to generate centrifugal force to accelerate gas flow, thereby increasing pressure and delivering gas. Centrifugal fans have advantages such as low noise, stable operation, convenient maintenance, and durability.

[0039] Of course, the intake fan can also be an axial flow fan. The gas flow direction is parallel to the fan axis of the axial flow fan, hence the name axial flow fan. Axial flow fans have advantages such as large air volume, low noise, low maintenance costs, and high safety and reliability.

[0040] In some embodiments of this invention, the exhaust fan is an axial flow fan. Of course, the exhaust fan can also be a centrifugal fan. The working principles and advantages of axial flow fans and centrifugal fans are as described in the above embodiments and will not be repeated here.

[0041] In some embodiments of this utility model, such as Figures 1 to 3 As shown, mounting brackets 118 are provided on the outer sides of both side walls of the cabinet 110. Each mounting bracket 118 includes a vertical plate 1181 fixed to the cabinet 110, a horizontal plate 1182 perpendicular to the bottom of the vertical plate 1181, and a connecting rib 1183 connecting the vertical plate 1181 and the horizontal plate 1182. Mounting holes 1184 are provided on the horizontal plate 1182.

[0042] In this embodiment, the electrical control cabinet 10 is mounted on the mobile crushing station via a mounting bracket 118. Specifically, the electrical control cabinet 10 can be installed and fixed by bolts passing through the mounting holes 1184 on the mounting bracket 118 and the corresponding holes on the mobile crushing station. The mounting bracket 118 facilitates the installation and removal of the electrical control cabinet 10.

[0043] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
