[0042] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the drawings and embodiments. [[ID=J45]]

[0043] Please refer to Figure 1 and Figure 2 In a specific embodiment, the protection installation device provided by the specific embodiment of the present utility model includes an installation frame 9, a pressing component and a clamping component. Among them, the protection installation device provided in this application can be installed in an intelligent control cabinet, for example, installed on an inverter cabinet body. The protection installation device can be specifically installed at the air inlet and / or air outlet position of the control cabinet.

[0044] The edge of the installation frame 9 in the ventilation direction can be provided with a sealing strip 12, and the installation and sealing between the installation frame 9 and other structures are realized through the sealing strip 12.

[0045] As Figure 1 and Figure 4 shown, the pressing assembly includes a first pressing member 1 and a second pressing member 2. The first pressing member 1 is hinged to the second pressing member 2 through a hinge member 4. Specifically, the first ends of the first pressing member 1 and the second pressing member 2 are hinged through one or at least two hinge members 4.

[0046] An installation space for accommodating the protective member 3 is formed between the first pressing member 1 and the second pressing member 2, and the pressing assembly is inserted into the installation frame 9. The installation space is opened and closed by rotating the first pressing member 1 and the second pressing member 2. Among them, the protective member 3 can be a filter cotton, a filter net, or a protective structure formed by stacking the filter cotton and the filter net. Of course, in specific settings, the protective member 3 is not limited to the above situation.

[0047] Specifically, during installation, the protective member 3 can be installed in the installation space, or the end of the protective member 3 is fixedly pressed by the edges of the first pressing member 1 and the second pressing member 2.

[0048] As Figure 3 shown, in order to facilitate the opening of the first pressing member 1 and the second pressing member 2, preferably, the ends of the first pressing member 1 and the second pressing member 2 away from the hinge member 4 are not flush, that is, a step 14 for opening the first pressing member 1 and the second pressing member 2 is formed.

[0049] As Figure 4 shown, in a specific embodiment, the first pressing member 1 and the second pressing member 2 are hollow frame structures, and at least one of the inner cavities of the hollow frames of the first pressing member 1 and the second pressing member 2 is provided with a filter net 13 that cooperates with the protective member 3. At this time, the protective member 3 can be a filter cotton. Preferably, filter nets 13 are provided at positions of the first pressing member 1 and the second pressing member 2 facing the installation space. In order to extend the service life of the filter net 13, preferably, the filter net 13 is a metal net. Of course, when specifically used, it is also possible that the filter net 13 is made of a plastic structure or other wires (cotton threads) woven.

[0050] The clamping assembly is installed on the installation frame 9. Specifically, the installation frame 9 is installed on the cabinet body of the control cabinet and is installed at the ventilation opening position of the cabinet body as required. The installation frame 9 is specifically a hollow frame structure.

[0051] The clamping component is provided with a limiting groove for the clamping and pressing component. After the pressing component is inserted into the mounting frame 9, the pressing component is clamped in the limiting groove. In a specific embodiment, the clamping component can be a U-shaped plate member with an opening in the middle, and the opening in the middle forms the limiting groove. Specifically, one end of the pressing component away from the limiting groove is limited by the shape of the opening position of the mounting frame 9, or the same as the conventional fixing method can be selected.

[0052] As Figure 1 and Figure 4 shown, the pressing component further includes a push-pull handle 5, and the push-pull handle 5 is installed on the first pressing member 1 or the second pressing member 2. Alternatively, push-pull handles 5 can be provided on both the first pressing member 1 and the second pressing member 2. By providing the push-pull handle 5, it is convenient to operate the push-pull of the pressing component, and further convenient to replace the protective member 3.

[0053] In a specific embodiment, the push-pull handle 5 can be a handle structure protruding outward from the first pressing member 1 or the second pressing member 2. At this time, it is convenient for the operator to operate the push-pull handle 5. Or the push-pull handle 5 is a groove structure recessed in the first pressing member 1 or the second pressing member 2, and the push-pull handle 5 is set as a hidden structure of the groove to avoid interference between the push-pull handle 5 and other structures.

[0054] As Figure 4 shown, the push-pull handle 5 and the hinge member 4 are located on the same side of the pressing component. After specific assembly is completed, the push-pull handle 5 and the hinge member 4 are located at the opening position of the mounting frame 9. The free ends of the first pressing member 1 and the second pressing member 2 are fixed through the limiting groove. Such a setting makes the overall structure simple, the protective member 3 easy to replace, and reduces the replacement time of the staff. At the same time, by pushing and pulling the protective member 3 with the push-pull handle 5, the structure is stable, the damage to the pressing component is reduced, and the overall structure is stable and reliable.

[0055] Of course, in order to improve the installation stability of the protective member 3, the pressing component further includes an elastic buckle, and the elastic buckle is installed at one end of the first pressing member 1 away from the hinge member 4. One or at least two elastic buckles can be provided on the pressing component. When the first pressing member 1 and the second pressing member 2 are buckled, the elastic buckle is buckled on the second pressing member 2. Specifically, the elastic buckle can be an elastic plastic part or an elastic steel sheet on the first pressing member 1, and the operator opens the free ends of the first pressing member 1 and the second pressing member 2 by pressing the elastic buckle.

[0056] Specifically, the width of the limiting groove is determined according to the width of the pressing component, so that the pressing component can be inserted into the limiting groove and the pressing component can be fixed.

[0057] When the protective part 3 needs to be installed, place the protective part 3 between the first pressing part 1 and the second pressing part 2. Rotate the first pressing part 1 and the second pressing part 2 to install the protective part 3 in the installation space, and then insert the pressing component into the installation frame 9. The pressing component is inserted into the limiting groove. When the protective part 3 needs to be replaced, after pulling out the pressing component from the installation frame 9, rotate the first pressing part 1 and the second pressing part 2, take out the old protective part 3, and repeat the above steps for installation after replacing the new protective part 3.

[0058] As can be seen from the above description, in the protective installation device provided in the specific embodiment of the present application, the first pressing part 1 and the second pressing part 2 are hinged, and the protective part 3 is installed on the pressing component by rotating the first pressing part 1 and the second pressing part 2. That is, during maintenance, only the pressing cover plate needs to be pulled out to realize the opening and closing of the over-pressing component, and the replacement of the over-protective part 3 can be realized. The pressing component is installed in the limiting groove by plugging, and the pressing component can be directly taken and placed by pushing and pulling, which is simple in operation and effectively improves the replacement efficiency of the protective part 3.

[0059] In a specific embodiment, the clamping component can include two parts. Specifically, the clamping component includes a first limiting part 11 and a second limiting part 10. Both the first limiting part 11 and the second limiting part 10 are installed on the installation frame 9. Specifically, preferably, both the first limiting part 11 and the second limiting part 10 are detachably installed on the installation frame 9. The first limiting part 11 is provided with a first limiting portion for abutting against the outer surface of the first pressing part 1. The second limiting part 10 is provided with a second limiting portion for abutting against the outer surface of the second pressing part 2. A limiting groove is formed between the first limiting portion and the second limiting portion. By forming the limiting groove between the first limiting portion and the second limiting portion, during assembly, according to the size of the pressing component, the width of the limiting groove is designed, and then the relative positions of the first limiting part 11 and the second limiting part 10 are determined. That is, the first limiting part 11 and the second limiting part 10 can adapt to the installation requirements of pressing components of different sizes, thereby improving the versatility of the protective installation device.

[0060] In an assembly method, as Figure 1 shown, the first limiting part 11 and the second limiting part 10 are located at the bottom end of the installation frame 9. After assembly, the position of the push-pull handle 5 is at the top end of the installation frame 9, and the user vertically pushes and pulls the pressing component to realize the replacement of the protective part 3.

[0061] As Figure 3As shown, in a specific embodiment, the first limiting member 11 is used to install the shutter 8. Specifically, one end of the shutter 8 away from the first limiting member 11 is installed on the installation frame 9 through the third limiting member 6. The second limiting member 10 is provided with a guiding surface 1001 connected to the second limiting portion. Specifically, the inclination angle of the guiding surface 1001 is determined according to needs. One end of the guiding surface 1001 away from the second limiting portion extends obliquely away from the pressing assembly. To facilitate the smooth installation of the pressing shell assembly, specifically, the guiding surface 1001 extends along the end of the clamping assembly to the opposite ends of the clamping assembly. During specific use, during the forward movement of the pressing assembly with the protective member 3 installed, the guiding surface 1001 provided on the second limiting member 10 enables the pressing assembly to smoothly enter the limiting groove. During the forward movement, as the pressing assembly continuously enters the limiting groove, the limiting of the pressing assembly is realized, with simple operation and reduced operation time for the staff.

[0062] The limiting of the pressing assembly in this application is achieved through the first limiting member 11 for installing the shutter 8 in the existing structure, without the need to separately set a limiting structure, further simplifying the structure, reducing the number of additional parts, and lowering the manufacturing cost.

[0063] Specifically, the first limiting member 11 and the second limiting member 10 can specifically be plastic parts or metal parts. Preferably, the first limiting member 11 and the second limiting member 10 are processed from steel plates. When the pressing assembly is inserted into the limiting groove, the first limiting member 11 and the second limiting member 10 are slightly deformed away from the first limiting member 11 and the second limiting member 10 to clamp the pressing assembly and improve the installation stability of the pressing assembly.

[0064] As Figure 4 shown, rows of first pressing protrusions 101 for pressing the protective member 3 are provided at both opposite ends of the first pressing member 1, and a first pressing groove is provided between adjacent two first pressing protrusions 101. Rows of second pressing protrusions 201 for pressing the protective member 3 are provided at both opposite ends of the second pressing member 2, and a second pressing groove is provided between adjacent two second pressing protrusions 201. Specifically, the first pressing protrusions 101 and the second pressing protrusions 201 can be rectangular tooth structures. Alternatively, the surfaces of the first pressing protrusions 101 and the second pressing protrusions 201 that are in contact with the protective member 3 are arc surfaces, and specifically, the surfaces of the first pressing protrusions 101 and the second pressing protrusions 201 that are in contact with the protective member 3 are circular arc structures.

[0065] During processing, preferably, the first pressing protrusions 101 and the first pressing member 1 are an integrally formed structure, and the second pressing protrusions 201 and the second pressing member 2 are an integrally formed structure.

[0066] The first pressing protrusions 101 are located in the second pressing groove, and the second pressing protrusions 201 are located in the first pressing groove to press the protective member 3 when the first pressing member 1 and the second pressing member 2 are buckled. After such a setting, asFigure 5 As shown, after the protective member 3 is installed between the first pressing member 1 and the second pressing member 2, it is a curved surface structure. Specifically, the protective member 3 is arranged in an S-shaped corrugated shape. After the protective member 3 is installed, a folded structure with gaps is formed. During use, the air resistance of the protective member 3 is reduced, which is beneficial to the entry of air and increases the heat dissipation efficiency of the inlet and outlet air. The filter forms a folded structure with gaps, which can achieve a larger contact area, increase the dust capacity of the protective member 3, and improve the filtration efficiency. At the same time, due to the dust capacity of the filter cotton, the service life of the single-time protective member 3 is extended, and thus the time interval for replacing the protective member 3 is extended.

[0067] In a specific embodiment, along the arrangement direction of the first pressing protrusions 101, the first pressing protrusions 101 on the opposite sides of the first pressing member 1 correspond one by one and are coplanar, that is, the extension surfaces of the first pressing protrusions 101 on the opposite sides of the first pressing member 1 form the same surface. For example, when the first pressing protrusion 101 is a semi-cylindrical structure, the extension lines of the central axes of the semi-cylindrical planes of the first pressing protrusions 101 on the opposite sides coincide. Such a setting facilitates the folded installation of the protective member 3.

[0068] The protective installation device provided by the present application further includes a slide rail, and the slide rail is installed on the installation frame 9. Specifically, the slide rail can be detachably installed on the installation frame 9 through fasteners, and a chute for cooperating with the pressing assembly is formed on the slide rail. One slide rail can be provided. In order to improve the sliding stability of the pressing assembly, preferably, two slide rails are provided. The two slide rails are installed on the opposite sides of the clamping assembly and are slidably matched with the pressing assembly. At this time, the chutes of the two slide rails are arranged oppositely.

[0069] The protective installation device provided by the present application further includes a protective cover plate 7, and the protective cover plate 7 is detachably installed on the installation frame 9. Specifically, the protective cover plate 7 can be installed on the installation frame 9 through threaded fasteners, or one end of the protective cover plate 7 is hinged to the installation frame 9, and the other end is connected to the installation frame 9 through threaded fasteners or buckles. The protective cover plate 7 is used to block the opening position on the installation frame 9 where the pressing assembly is installed. By providing the protective cover plate 7, the installation stability of the protective member 3 and the pressing assembly is improved. At the same time, by providing the protective cover plate 7, the situation that impurities enter through the opening position on the installation frame 9 where the pressing assembly is installed and contaminate the protective member 3 is avoided, and the service time of the protective member 3 is extended.

[0070] When replacing the protective member 3, the protective cover plate 7 is removed, and the pressing assembly is pulled out through the push-pull handle 5. The first pressing member 1 and the second pressing member 2 are directly opened, the protective member 3 is placed according to a preset path, and then the first pressing member 1 and the second pressing member 2 are pressed together. By pushing forward through the push-pull handle 5, during the pushing process, the preset oblique angle of the guiding surface 1001 enables the pressing assembly to move along the preset path, and finally the end of the pressing assembly is locked through the limiting groove.

[0071] The protective installation device provided by the present application enables the rapid disassembly and assembly of the protective member 3 by means of an existing structure. The overall structure is simple, safe and reliable, and is convenient for wide promotion and use.

[0072] A cabinet provided by the present application includes a protective installation device and a protective member 3 installed on the protective installation device, wherein the protective installation device is any one of the above-mentioned protective installation devices.

[0073] Among them, the protective member 3 can be a filter cotton, a filter net, or a protective structure formed by stacking a filter cotton and a filter net. Of course, in specific settings, the protective member 3 is not limited to the above situation.
