Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-8, in an embodiment of the present invention, a high-efficiency heat dissipation low-voltage switch cabinet convenient for disassembling and assembling a filter screen includes a cabinet body 1, an upper base plate 2, an opening/closing door 3 and an installation base 4; the cabinet body is fixedly arranged on an upper bottom plate 2, an opening and closing door 3 is hinged to the front side of the cabinet body 1, the upper bottom plate 2 is fixedly arranged on the upper end surface of the cabinet body 1, and an installation base 4 is hollow; a vent 7 is formed in one side of the mounting base 4, an embedded groove 12 is formed in the rear side of the mounting base 4 corresponding to the vent 7, mounting sliding grooves 13 are formed in the embedded groove 12 at equal intervals, and the mounting sliding grooves 13 penetrate through a side plate of the mounting base 4 where the embedded grooves 12 are located and are stopped in a side plate coplanar with the opening and closing door 3; the installation chutes 13 are internally and slidably provided with filter screen groups 6 embedded in the screen frame 10, and the screen frame 10 is clamped with the installation base 4 through elastic sealing gaskets 14 arranged in the installation chutes 13 and clamping devices arranged at the upper end of the installation base 4; an air suction fan 17 is fixedly arranged on the lower bottom plate of the cabinet body 1, a first heat dissipation fan 18 and a second heat dissipation fan 19 are fixedly arranged on the inner sides of the upper bottom plate 2 and a side plate of the cabinet body respectively, and an exhaust fan 5 communicated with the outside is arranged on the other side of the cabinet body 1.
Wherein, latch device includes wedge 11, wedge 11 passes through spacing mounting groove 15 and installation base 4 sliding connection, 11 upper ends fixedly connected with reset spring 16 of wedge, the other end of reset spring 16 is fixed to be set up the up end at spacing mounting groove 15, the upper portion of wedge 11 is still fixed and is provided with dismounting rod 9, dismounting rod 9 passes switching groove 8, switching groove 8 is seted up on the installation base 4 outer wall that corresponds with spacing mounting groove 15 and is run through the part between spacing mounting groove 15 and the installation base 4. The length of the part of the wedge block 11 which protrudes out of the upper bottom surface of the embedding groove 12 in the working state is smaller than the actual moving height of the dismounting rod 9 in the opening and closing groove 8. The return spring 16 is a compression spring, and in the working state, the lowest end of the wedge block 11 is lower than the upper end surface of the net frame 10. The air suction fan 17 and the exhaust fan 5 are both one-way fan bodies; and the exhaust direction of the air suction fan 17 is upward and the exhaust direction of the exhaust fan 5 is outward. The air suction fan 17 sucks air into the cabinet body 1 through the ventilation opening 7, and the exhaust fan exhausts hot air in the cabinet body 1, so that the purpose of cooling is achieved. The depth of the caulking groove 12 is larger than the sum of the thickness of the net frame 10 and the thickness of the wedge block 11. Ensuring that the cabinet body 1 does not protrude in the installation state.
When in use: the whole heat dissipation principle of this device is that the fan 17 of breathing in inhales the cabinet body 1 after filtering the lower air of outside temperature through filter screen group 6 in, the higher gas of temperature in the cabinet body 1 is blown with second heat dissipation fan 19 to first heat dissipation fan 18, thereby make the gaseous exchange of the different parts of cabinet body 1, thereby prevent that the high temperature that some components and parts that are difficult to carry out gas exchange produced can't be discharged and the device that leads to damages, under the effect of first heat dissipation fan 18 and people's second heat dissipation fan 19, can ensure that the temperature in the cabinet body 1 is balanced, rethread exhaust fan 5 is outside the cabinet body 1 with the higher gas discharge of temperature, thereby reach the purpose of cooling in the cabinet body 1, it needs to be noted that, exhaust fan 5 sets up because the density is low under the high gas normal condition of temperature in the top of the fan 17 of breathing in, namely in the eminence. The exhaust fan 5 is provided on the side plate because the side is opposite to the upper bottom plate 2, and the probability of dust falling into the cabinet 1 is lower.
The filter screen group 6 dismounting process of the device is as follows: taking the disassembly process as an example, as shown in fig. 3-6: the dismounting rod 9 is shifted upwards along the opening and closing groove 8, so that the wedge block 11 is driven to move upwards along the mounting sliding groove 13, the clamping surface of the wedge block 11 is separated from the contact of the screen frame 10, the clamping is separated, the screen frame 10 is popped out for a short distance under the action of the elastic sealing gasket 14, and a worker can conveniently pull out the screen frame 10 and the corresponding filter screen group 6; it should be noted that when inserting the filter screen assembly 6, the screen frame 10 presses the wedge block 11 upwards along the inclined surface of the wedge block 11, and when the screen frame 10 is completely installed correctly, the wedge block 11 is separated from the contact of the wedge block 11, and the wedge block 11 moves downwards rapidly under the action of the return spring 16, completing the stable clamping with the screen frame 10. The elastic sealing gasket 14 is actually forced to deform during the installation of the frame 10, which ensures that the filter screen assembly 6 is pushed to a position suitable for drawing by the elastic force when the filter screen assembly 6 is disassembled, and also ensures the sealing performance during the installation.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
