Description

Technical Field

[0001] This utility model relates to the field of control box technology, specifically to a waterproof and dustproof control box suitable for harsh environments. Background Technology

[0002] Waterproof and dustproof control boxes are enclosures specifically designed to protect electrical and electronic equipment from harsh environments. These control boxes are typically used in industrial environments such as manufacturing plants, outdoor facilities, ships, and other places where they may encounter high humidity, dust, corrosive substances, or extreme temperature changes.

[0003] However, the control box is not convenient to operate when installing electrical components, and the installation efficiency is low. This makes the disassembly and installation process cumbersome, increasing maintenance costs and time. At the same time, the filter components of the control box will accumulate dust and impurities after long-term use. If they are not cleaned in time, they will affect the filtration effect and heat dissipation efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a waterproof and dustproof control box suitable for harsh environments, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A waterproof and dustproof control box suitable for harsh environments includes a control box body. The inner wall of the control box body is provided with a mounting assembly. The mounting assembly includes a mounting bracket provided on one side of the inner wall of the control box body. One side of the mounting bracket is fixed with mounting seats distributed at equal intervals. The mounting seats are provided with mounting grooves above and below. Multiple mounting holes are provided on the mounting grooves. A spring-loaded telescopic rod is fixedly connected to the inner wall of the mounting hole. One end of the spring-loaded telescopic rod is fixed with a limit block. One end of the limit block is engaged with the inner wall of the mounting groove.

[0008] Furthermore, in order to better clean and collect the impurities attached to the filter screen, auxiliary components are provided at the top and bottom of the control box. The auxiliary components include auxiliary ports opened at the top and bottom of the control box. An auxiliary frame is fixed to the inner wall of the auxiliary port. The inner wall of the auxiliary frame is equipped with a filter screen and a molecular sieve screen. An electric telescopic rod is installed on the auxiliary frame. A cleaning brush is fixed to one end of the electric telescopic rod. Both ends of the cleaning brush contact the inner wall of the auxiliary frame. The cleaning end of the cleaning brush contacts one side of the filter screen. A collection groove is opened on one side of the auxiliary frame. A collection box is installed on the inner wall of the collection groove.

[0009] Furthermore, in order to better assist in heat dissipation of the control box, an exhaust fan is installed on the inner wall of one of the auxiliary frames, with the exhaust fan located above one of the molecular sieve plates.

[0010] Furthermore, in order to better assist in fixing the wires connected to the installed electrical components, equidistant wire fixing bases are fixedly installed below the mounting bracket, and equidistant wire fixing grooves are opened on one side of the wire fixing bases.

[0011] Furthermore, to better improve the waterproof and dustproof protection of the control box, an opening is provided on one side of the control box, and a sealing door is hinged to the opening. A sealing gasket is provided on one side of the sealing door, and one side of the sealing gasket contacts the opening.

[0012] Furthermore, to prevent the mounting base from sliding out of the mounting groove, a limiting plate is engaged with the inner wall of the mounting groove, and the limiting plate is adapted to the inner wall of the mounting groove.

[0013] Furthermore, in order to better secure the control box, multiple mounting brackets are fixed on one side of the control box, and multiple bolts are threaded onto the mounting brackets.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) The installation components installed in the control box can not only automatically position and fix the components, greatly simplifying the installation operation, but also eliminate the need to disassemble a large number of screws or other fasteners, saving maintenance time and labor costs. At the same time, the auxiliary components installed in the control box can not only effectively clean the dust and impurities attached to the filter screen, preventing excessive dust accumulation from clogging the mesh, which is beneficial to the heat dissipation of the internal electrical components, but also collect the cleaned impurities in a concentrated manner, avoiding the secondary flying and accumulation of impurities inside the control box, reducing the risk of equipment failure caused by dust and impurities, and improving the reliability and service life of the control box in harsh environments.

[0016] (2) The cable holders installed on the mounting bracket can make the wires neatly arranged and reasonably laid out, avoiding the messy tangling and accumulation of wires. This reduces the risk of wire damage, short circuit or poor contact caused by factors such as vibration during equipment operation or the weight of the wires themselves. It makes it convenient for technicians to quickly find the corresponding wires for operation without having to search through messy cables, saving maintenance and repair time. At the same time, the sealing door and sealing gasket installed on the control box can form a reliable protective barrier at the opening of the control box, effectively preventing external water, dust, dirt and other contaminants from entering the control box, ensuring the safe operation of electrical components in harsh environments and extending the service life of the control box.

[0027] Example 1:

[0028] like Figures 1-6 As shown, a waterproof and dustproof control box suitable for harsh environments according to an embodiment of the present utility model includes a control box body 1. The inner wall of the control box body 1 is provided with an installation component 2. The installation component 2 includes a mounting bracket 201 provided on one side of the inner wall of the control box body 1. The mounting bracket 201 has a U-shaped cross-section and is used to install and fix the mounting base 202. The mounting base 202 is fixed on one side of the mounting bracket 201 and is distributed at equal intervals for installing electrical components. The number of mounting bases 202 can be adjusted according to the actual situation, so the specific number is not detailed.

[0029] Mounting base 202 has mounting grooves 203 on the top and bottom. A limiting plate 9 is snapped into the inner wall of the mounting groove 203. The limiting plate 9 is adapted to the inner wall of the mounting groove 203. There are four mounting holes on the mounting groove 203, with two holes forming a group. A spring-loaded telescopic rod 204 is fixedly connected to the inner wall of the mounting hole.

One end of telescopic rod one is nested with the inner wall of telescopic rod two through a sealing block or sealing gasket. The spring is fitted outside telescopic rod one and telescopic rod two. A limiting block 205 is fixed to one end of the spring-loaded telescopic rod 204. One end of the limiting block 205 is snapped into the inner wall of the mounting groove 203.

[0030] The mounting bracket 201 is fixedly provided with equidistantly distributed wire fixing bases 5. The number of wire fixing bases 5 can be adjusted according to the actual situation, so the specific number is not detailed. One side of the wire fixing base 5 is provided with equidistantly distributed wire fixing grooves 6 for fixing the connecting wires of electrical components inside the control box. One side of the control box 1 is provided with an opening, and a sealing door 7 is hinged at the opening to block external dust and moisture. A sealing gasket 8 is provided on one side of the sealing door 7 to improve the sealing performance. One side of the sealing gasket 8 contacts the opening. Two fixing brackets 10 are fixed on one side of the control box 1, and two bolts 11 are threadedly connected to the fixing brackets 10.

[0031] Example 2:

[0032] like Figures 1-6 As shown, a waterproof and dustproof control box suitable for harsh environments according to an embodiment of the present utility model is provided with auxiliary components 3 above and below the control box body 1. The auxiliary components 3 include auxiliary openings opened above and below the control box body 1. An auxiliary frame 301 is fixed to the inner wall of the auxiliary opening. A filter screen plate 302 and a molecular sieve plate 303 are provided on the inner wall of the auxiliary frame 301. The filter screen plate 302 and the molecular sieve plate 303 are detachable and replaceable structures, and are conventional technologies, so they are not described in detail.

[0033] One of the auxiliary frames 301 has an exhaust fan 4 installed on its inner wall, with the exhaust fan 4 positioned near the molecular sieve plate 303. An electric telescopic rod 304 is installed on the auxiliary frame 301. During actual use, the electric telescopic rod 304 and the exhaust fan 4 are electrically connected to a temperature and humidity sensor (not shown in the figure). The temperature and humidity sensor, the electric telescopic rod 304, and the exhaust fan 4 are electrically connected to a controller and an external power supply during actual use; this is conventional technology and therefore not detailed. A cleaning brush 305 is fixed to one end of the electric telescopic rod 304. Both ends of the cleaning brush 305 contact the inner wall of the auxiliary frame 301, and the cleaning end of the cleaning brush 305 contacts one side of the filter plate 302. A collection groove is provided on one side of the auxiliary frame 301, and a collection box 306 is installed on the inner wall of the collection groove to collect impurities during cleaning. The collection boxes 306 installed on the two auxiliary frames 301 are of different sizes (see attached figure). Figure 5 , 6 ).

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, with the help of the above-mentioned technical solution of this utility model, during installation, the worker can quickly install the fixing bracket 10 on the side of the control box 1 with the bolts 11, and then open the sealing door 7. Then, the limiting plate 9 in the mounting groove 203 is taken out, which makes it easier to insert the component into the mounting groove 203. When the mounting base 202 is inserted into the mounting base 202, the limiting block 205 of the spring-loaded telescopic rod 204 is compressed and contracted by the component. Then, the spring rebounds and pushes the limiting block 205 to lock the component, realizing fast fixing without screws. After installation, the limiting plate 9 is engaged with the inner wall of the mounting groove 203 to prevent the mounting base 202 from accidentally slipping out and to ensure the stability of the component. Then, the sealing door 7 is closed, and the sealing gasket 8 of the sealing door 7 fits tightly with the opening of the control box 1 to block external moisture and dust.

[0036] During use, the exhaust fan 4 accelerates the airflow inside the box. Then, the external gas passes through the filter screen 302 set in the auxiliary frame 301 below the control box 1 to intercept large dust particles, and the molecular sieve screen 303 adsorbs fine particles and water vapor. This double protection prevents impurities from entering the control box 1. The gas then undergoes hot and cold gas exchange. The exchanged gas is transported by the exhaust fan 4 to the filter screen 302 set in the auxiliary frame 301 above the control box 1 to intercept large dust particles, and the molecular sieve screen 303 adsorbs fine particles and water vapor. This double protection prevents impurities from entering the control box 1. Finally, the gas is discharged from the control box 1.

[0037] When cleaning is required, the electric telescopic rod 304 periodically drives the cleaning brush 305 to move along the surface of the filter screen 302, sweeping off the attached dust and impurities. The dust or impurities fall into the collection box 306 set in the auxiliary frame 301 to prevent secondary flying. The cable fixing seat 5 and cable fixing groove 6 set in the mounting bracket 201 can classify and fix the wires to prevent tangling or vibration damage.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
