Description

Technical Field

[0001] The present invention belongs to the technical field of equipment related to reactive power compensation cabinets, and in particular relates to a reactive power compensation cabinet. Background Art

[0002] The reactive power compensation cabinet is a common cabinet. Its main function is to compensate for the reactive power in the power system in which it is located. To this end, it is equipped with a large number of capacitive and inductive components inside, which causes the compensation cabinet to dissipate a large amount of heat during operation. Heat dissipation vents are opened on the side wall of the cabinet to cooperate with the heat dissipation single eye to dissipate heat inside the cabinet.

[0003] Dust screens are usually installed at the heat dissipation vents to prevent external dust from entering the cabinet. However, dust accumulation on the dust screens affects the heat dissipation effect inside the cabinet. The heating and ventilation wind speeds easily bring in accumulated dust. Moreover, if the dust screens are cleaned directly from the outside, the accumulated dust can easily enter the cabinet and affect the normal operation of the internal components. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a reactive compensation cabinet, which performs double dust protection at the heat dissipation outlet to improve the dust protection effect, and the inner and outer dust protection components can be separated, and the outer layer can be automatically cleaned.

[0005] The technical solution adopted by the present invention is as follows: a reactive compensation cabinet, comprising a base and a cabinet body located on the base, heat dissipation ports being opened at the lower parts of both sides of the cabinet body, double dustproof components being arranged at the heat dissipation ports, and corresponding dustproof operations being performed at the heat dissipation ports, and a cleaning unit being assembled on the outer layer of the double dustproof component for performing corresponding cleaning operations on the outer layer of the double dustproof component.

[0006] Furthermore, the double dustproof assembly includes a fixed frame, an inner dustproof unit and an outer dustproof part; the fixed frame is assembled on the outside of the heat dissipation port and has corresponding supporting force; the inner dustproof unit is installed at the fixed frame and matches the heat dissipation port to perform corresponding dustproof operations at the heat dissipation port; the outer dustproof part includes a rotating frame and is hinged to the fixed frame; the outer dustproof unit is installed in the rotating frame.

[0007] Furthermore, the cleaning unit includes a driving portion provided on the rotating frame and a cleaning rod connected to the driving portion. The cleaning rod is moved along the surface of the outer protective unit by the driving portion to perform corresponding cleaning operations.

[0008] Furthermore, the outer dustproof unit includes a dustproof frame rotatably installed in the rotating frame through a rotating shaft and a dustproof net installed inside the dustproof frame.

[0009] Furthermore, the inner dustproof unit is a pull-out dustproof net with a pull-out handle provided on the top, and corresponding dustproof blocking operations are performed at the heat dissipation outlet.

[0010] Furthermore, an exhaust port is provided at the top of the cabinet, and an exhaust fan is provided in the exhaust port.

[0011] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0012] (1) The double dustproof components can improve the dustproof effect and adapt to more severe working environments. Secondly, the inner dustproof unit can be separated from the outer dustproof unit, and only a single layer is used for dustproofing, which is more flexible to use.

[0013] (2) The outer dustproof unit can be automatically cleaned by the provided cleaning unit. In addition, during cleaning, the inner dustproof unit is blocked at the heat dissipation outlet to prevent the dust raised during cleaning from entering the interior of the cabinet. The inner dustproof unit can be taken out and replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0022] like Figure 1-Figure 3 As shown, a reactive compensation cabinet is shown, which includes a base 1 and a cabinet body 2 located on the base 1, an exhaust port 12 is provided at the top of the cabinet body 2, an exhaust fan is provided in the exhaust port 12, and heat dissipation ports 3 are provided at the lower parts of both sides of the cabinet body 2, a double dustproof component is provided at the heat dissipation port 3, and corresponding dust prevention operations are performed at the heat dissipation port 3. The outer layer of the double dustproof component is equipped with a cleaning unit for performing corresponding cleaning operations on the outer layer of the double dustproof component. When heat is dissipated inside the cabinet body 2, the exhaust fan can be started (multiple groups of exhaust fans can be provided), and the external air flow enters the cabinet body 2 from the lower parts of both sides of the cabinet body 2, takes away the heat inside the cabinet body 2 and is discharged from the top exhaust port 12 to complete one-time heat dissipation. Before the external air flow enters the heat dissipation port 3, it passes through the double dustproof component to filter dust and other particles and then enters the cabinet body 2. Most of the dust is intercepted on the outside of the double dustproof component. The cleaning unit is used to automatically clean the outside of the double dustproof component to ensure the effect of dust prevention and heat dissipation. During cleaning, the dust is blocked by the inner layer outside the heat dissipation port 3 to avoid entering the inside of the cabinet body 2.

[0023] In some preferred embodiments, the double dustproof assembly includes three parts: a fixing frame 4, an inner dustproof unit 5, and an outer dustproof portion. Double dustproof is performed on the outside of the heat dissipation port 3, which is more adaptable to harsh working environments. The fixing frame 4 is assembled on the outside of the heat dissipation port 3 and has corresponding supporting force.

[0024] The inner dustproof unit 5 is installed at the fixed frame 4 and matches the heat dissipation port 3, and the corresponding dustproof operation is performed at the heat dissipation port 3. Here, preferably, the inner dustproof unit 5 is a pull-out dustproof net with a pull-out handle 11 provided on the top, and the corresponding dustproof barrier operation is performed at the heat dissipation port 3. Furthermore, the dustproof net can be pulled in and out of the fixed frame 4 from the top, and dust is prevented at the heat dissipation port 3, and can be easily replaced or removed, and only the outer dustproof part is used for dust prevention.

[0025] The outer dustproof part includes a rotating frame 6 and is hinged to the fixed frame 4; the outer dustproof unit 7 is installed in the frame of the rotating frame 6, and preferably, the outer dustproof unit 7 includes a dustproof frame 10 installed in the rotating frame 6 by rotating the rotating shaft and a dustproof net installed inside the dustproof frame 10. One side of the dustproof frame 10 is detachably connected to the rotating shaft and can be detached from the rotating shaft through a semi-open sleeve (a plug-in interface is provided on the side wall and has a certain deformation force, which is wrapped around the outside of the rotating shaft so that the dustproof frame 10 is detachably connected to the rotating shaft); the dustproof frame 10 can rotate; in addition, the rotating frame 6 can rotate so that the cleaning unit and the outer dustproof unit 7 rotate synchronously, forming a certain angle with the heat dissipation port 3, which can reduce the dust entering the cabinet 2 during cleaning, and when necessary, when the outer dustproof unit 7 rotates away from the heat dissipation port 3, dust is prevented by the inner dustproof unit 5, separating the inner and outer dustproof units 7, and reducing the barrier to external airflow.

[0026] In some preferred embodiments, the cleaning unit includes a driving portion provided on the rotating frame 6 and a cleaning rod 8 connected to the driving portion, wherein the cleaning rod 8 is moved along the surface of the outer protective unit by the driving portion to perform the corresponding cleaning operation. Preferably, the driving portion is provided in a shell formed at the top of the rotating frame 6, and a limit groove is provided at the bottom of the shell along the moving direction, and the top of the cleaning rod 8 is movable through the limit groove and can move along the limit groove; the driving portion includes a driving motor 9, which is provided at one end of the shell, and a support screw 13 is rotatably installed between the two ends of the shell. One end of the support screw 13 extends out of the shell and is fixedly connected to the output end of the driving motor 9. The driving motor 9 provides a rotational driving force to the support screw 13. The end of the cleaning rod 8 extending into the shell moves along the central axis direction of the support screw 13 through a moving block, and the moving block is threadedly connected to the support screw 13. After starting the driving motor 9, the output end of the driving motor 9 rotates to drive the support screw 13 to rotate. When the support screw 13 rotates, the moving block carries the cleaning rod 8 to move, thereby cleaning the dustproof net of the outer dustproof unit 7.

[0027] The specific usage is as follows: the cabinet 2 of the present application is installed and placed in a suitable working position; when cleaning the dustproof net at the heat dissipation port 3, the dustproof net of the outer dustproof unit 7 can be cleaned through the cleaning unit, and the dustproof net of the inner dustproof unit 5 blocks the flying dust from entering the interior of the cabinet 2 during cleaning; the inner dustproof unit 5 can be pulled out for replacement, so the dustproof net of the above-mentioned double dustproof assembly is easy to replace and clean.

[0028] In addition, when double protection is not required, the outer dustproof part can be rotated away from the heat dissipation port 3 by the rotating frame 6, or the inner dustproof unit 5 can be removed to perform single-layer dust protection according to specific needs.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
