Description

Technical Field

[0001] The present application relates to the technical field of protection of power conversion systems, and in particular to a protection device for a power conversion system. Background Art

[0002] In order to adapt to lighting lamps of different powers, a power conversion system is used to convert an input power supply into a power supply output of different powers. After the circuit design of the power conversion system is completed, the electrical connection components required in the circuit are generally all installed on a carrier that can protect the electrical connection components. For example, the carrier can specifically be a box structure. All electrical connection components are supported and accommodated by the box. Only the socket jacks are located outside the box for the power cord of the lighting lamp to be plugged in. Other electrical connection components are installed inside the box, and the box is also equipped with a box cover for covering. Using the box as the carrier, the cooperation of the box and the box cover can not only protect the electrical connection components, but also facilitate people to carry the entire power conversion system to different environments for use.

[0003] However, during the actual operation process, when it is necessary to open the box cover to observe the internal electronic components, due to environmental factors, sundries may fall into the box, causing damage to the electronic components. Summary of the Utility Model

[0004] In order to further protect the electrical connection components of the power conversion system, the present application provides a protection device for a power conversion system.

[0005] The present application provides a protection device for a power conversion system, adopting the following technical solutions:

[0006] A protection device for a power conversion system includes a box body, a box cover installed on the box body, and a protection plate detachably installed inside the box body. An installation space for accommodating electrical connection components is formed between the box body and the protection plate, and the protection plate is made of an insulating and transparent material.

[0007] By adopting the above technical solutions, when the electrical connection components of the power conversion system are all installed on the box body, first install the protection plate. An installation space for accommodating electrical connection components is formed between the box body and the protection plate. The protection plate plays a first-layer covering role for the electrical connection components. Then install the box cover to play a second-layer covering role. The box cover not only plays a covering and protecting role for the electrical connection components, but also plays a covering and protecting role for the protection plate. When the box cover is opened, the working state of the internal components can be directly observed through the transparent protection plate, which is convenient for monitoring and maintenance. At the same time, the protection plate can block foreign sundries from entering the box body, so that the protection plate plays a protective role for the electrical connection components, thereby further realizing the protection effect of the electrical connection components of the power conversion system. Moreover, when a non-professional person opens the box cover, due to the setting of the protection plate, the risk of personnel accidentally touching the internal components and getting injured can also be avoided.

[0008] Optionally, support columns are installed inside the box body, and the protection plate abuts against the upper end surfaces of the support columns. There are multiple support columns distributed along the box body.

[0009] By adopting the above technical solution, the design of the support columns provides a stable support platform for the protection plate, ensuring the stable position of the protection plate within the installation space, preventing displacement caused by vibration or external forces, and thus protecting the safety of the internal electrical components.

[0010] Optionally, a first fixing member is installed between the support column and the protection plate.

[0011] By adopting the above technical solution, the addition of the first fixing member further enhances the connection strength between the protection plate and the support column, making the protection plate not easily fall off or loosen when subjected to external forces, and improving the stability and reliability of the entire protection device.

[0012] Optionally, a support plate is installed on the support column, and a second fixing member is installed between the support plate and the protection plate.

[0013] By adopting the above technical solution, the support plate provides an additional support point for the protection plate. Combined with the use of the second fixing member, a more stable fixing structure is formed. This design enhances the stability of the protection plate in multiple directions and better protects the internal electrical components.

[0014] Optionally, a third fixing member is installed between the support plate and the support column.

[0015] By adopting the above technical solution, the third fixing member ensures the tight connection between the support plate and the support column, preventing the support plate from loosening or shifting during use, thus ensuring the structural integrity and stability of the entire protection device. And when overhauling the electrical connection components inside the box body, the support plate can be disassembled to increase the operating space inside the box body.

[0016] Optionally, both the second fixing member and the third fixing member are fixing bolts. The support column is provided with threaded holes for threaded connection of the third fixing member, the support plate is embedded with nuts, and the second fixing member is threadedly connected to the nuts.

[0017] By adopting the above technical solution, using fixing bolts as fixing members and combining with the threaded hole design on the support column, a fast and simple installation and disassembly process is achieved. At the same time, the threaded connection has high strength and stability, can withstand large external forces, and ensures the durability of the fixing effect.

[0018] Optionally, ribs extend on the surface of the support plate, the ribs contact the protection plate, and a spacing for accommodating the nut of the third fixing member is left between the protection plate and the support plate.

[0019] By adopting the above technical solution, the reserved spacing provides sufficient accommodation space for the nut of the third fixing member, avoiding direct extrusion of the nut on the protection plate.

[0020] Optionally, a spacing is left between the support column and the inner wall of the box body, side plates are installed on the circumferential side of the support column, and the side plates are fixedly connected to the inner wall of the box body.

[0021] By adopting the above technical solution, leaving a spacing between the support column and the inner wall of the box body can better support the protection plate, and the installation of the side plates enhances the overall connection strength between the support column and the box body, improving the overall stability of the protection device.

[0022] Optionally, a clamping block is installed on the support plate, a clamping groove is formed in the clamping block, and the clamping block is inserted into the side plate through the clamping groove.

[0023] By adopting the above technical solution, the design of the clamping block and the clamping groove provides a fast and convenient fixing method, making the connection between the support plate and the side plate more flexible and convenient. At the same time, this connection method also has a certain self-locking property, which can prevent the support plate from loosening or falling off during vibration to a certain extent.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. The design of the insulating transparent protection plate allows operators to directly observe the working state of the internal electrical connection components. The selection of the insulating material also ensures the safety of the operators, and can prevent sundries from falling into the box body during observation, enabling the protection plate to play a protective role for the electrical connection components;

[0026] 2. When non-professionals open the box cover, the protection plate can also avoid the risk of personnel accidentally touching the internal components and getting injured.

[0027] 3. The double covering and protection of the box cover and the protection plate can also better protect the electrical connection components during carrying or transportation. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] The following further describes the present application in detail Figure 1-6 with reference to the accompanying drawings.

[0036] Embodiment 1

[0037] Referring to Figure 1 , this embodiment discloses a protection device for a power conversion system, including a box body 1, a box cover 2 installed on the box body 1, and a protection plate 3 detachably installed in the box body 1. One end of the box cover 2 is hinged to the box body 1, and the other end of the box cover 2 is fixedly connected to the box body 1 through a buckle. The protection plate 3 is located between the box body 1 and the box cover 2, and there is a gap between the upper surface of the protection plate 3 and the inner wall of the box cover 2. An installation space for accommodating electrical connection components is formed between the box body 1 and the protection plate 3, and the protection plate 3 is made of an insulating and transparent material, specifically, a polycarbonate (PC) material with enhanced light transmission performance can be used to ensure the safety of operators and facilitate the observation of internal components. Warning signs such as "Pay attention to safety. Do not touch by non-professionals" are engraved or pasted on the protection plate 3. When a non-professional person opens the box cover 2, the setting of the protection plate 3 can also avoid the risk of personnel accidentally touching internal components and getting injured.

[0038] Referring to Figure 2 , support columns 4 are installed at the four corners of the bottom of the box body 1, and these support columns 4 are fixedly connected to the bottom of the box body 1 by welding to achieve stable support for the protection plate 3. The protection plate 3 abuts against the upper end surfaces of the support columns 4, thereby forming a stable support structure.

[0039] Referring to Figure 1 and Figure 2, To further enhance the stability of the protective plate 3, a first fixing member 7 is installed between the support column 4 and the protective plate 3, and the first fixing member 7 uses screws. Threaded holes for the threaded installation of screws are provided on the support column 4, and the support column 4 and the protective plate 3 are connected by screws to achieve a stable installation.

[0040] The implementation principle of Embodiment 1 is as follows: In this embodiment, the insulating and transparent protective plate 3 effectively protects the electrical connection components inside the box body 1 and facilitates observing their working states. When the box cover 2 is opened, it can also prevent foreign objects from falling into the box body 1, further ensuring the safety of the electrical connection components. In addition, by using the support columns 4 distributed at the four corners and the connection of screws, the stable support and detachable property of the protective plate 3 are realized, thus simplifying the maintenance operation and improving the stability of the overall structure.

[0041] Embodiment 2

[0042] Referring to Figure 3 , on the basis of Embodiment 1, a support plate 5 is added in this embodiment to increase the support area of the protective plate 3 and improve the stability of the protective plate 3. Specifically, the support plate 5 is installed on the support column 4, and the support plate 5 is located between the support column 4 and the protective plate 3. By adding the support plate 5, the supported area of the protective plate 3 can be significantly increased. When the box cover 2 is opened and the protective plate 3 is impacted by foreign objects such as falling rocks with impact force, the pressure borne by the protective plate 3 can be effectively dispersed, improving the stability and load-bearing capacity of the protective plate 3.

[0043] In addition, a second fixing member 8 is also installed between the support plate 5 and the protective plate 3, further enhancing the structural stability. At the same time, a third fixing member 9 is also installed between the support plate 5 and the support column 4 to ensure the stability and rigidity of the entire support structure. These fixing members can all use standard fasteners to achieve rapid installation and disassembly.

[0044] Referring to Figure 4 , further, both the second fixing member 8 and the third fixing member 9 select fixing bolts in this embodiment to achieve a more stable connection. Threaded holes are provided on the support column 4 for the threaded connection of the third fixing member 9. Nuts 10 are embedded on the support plate 5 for threaded connection with the second fixing member 8.

[0045] Ribs 51 extend from the surface of the support plate 5, and the ribs 51 are in contact with the protective plate 3 to enhance the support effect. At the same time, a spacing is reserved between the protective plate 3 and the support plate 5, and this spacing is used to accommodate the nuts of the third fixing member 9. The nuts are located below the protective plate 3, so as to ensure that the nuts will not contact the protective plate 3 and keep the flatness of the protective plate 3.

[0046] The implementation principle of Embodiment 2 is as follows: In this embodiment, by adding a support plate 5 and using fixing bolts as connectors, not only is the supported area of the protection plate 3 increased, but also a stable connection between the support plate 5, the protection plate 3, and the support column 4 is achieved. When electrical connection components need to be repaired and professionals remove the protection plate 3, although the area of the support plate 5 is not large, if the support plate 5 is also removed, the operable space inside the box body 1 can be increased.

[0047] Embodiment 3

[0048] Referring to Figure 5 , on the basis of Embodiment 2, this embodiment further improves the connection structure between the support column 4 and the inner wall of the box body 1. Specifically, there is a gap between the support column 4 itself and the inner wall of the box body 1, and each support column 4 is provided with two side plates 6, and a 90-degree angle is formed between these two side plates 6. The support column 4 is stably installed between these two side plates 6, thereby enhancing its stability. The arrangement of the support column 4 and the side plates 6 enables the support plate 5 to better support the protection plate 3.

[0049] Referring to Figure 6 , a clamping block 52 is installed on the side of the support plate 5 close to the side plate 6. The clamping block 52 includes a connecting portion 521 and a clamping portion 522, and the connecting portion 521 and the clamping portion 522 are integrally formed. The connecting portion 521 is fixedly connected to the support plate 5, and a clamping groove 53 is formed in the clamping portion 522. The clamping block 52 is inserted into the side plate 6 through the clamping groove 53.

[0050] In addition, the clamping grooves of the clamping blocks 52 on the support plate 5 correspond to the side plates 6 one by one. This design makes the position of the support plate 5 fixed in the horizontal direction and unable to move after being connected to the side plate 6 through the clamping block 52. This greatly enhances the stability of the support plate 5.

[0051] Combined with the third fixing member 9 in Embodiment 2, the installation stability between the support plate 5 and the support column 4 is significantly improved. This stable connection structure not only ensures the overall stability of the protection device.

[0052] The implementation principle of Embodiment 3 is as follows: By improving the connection structure between the support column 4 and the inner wall of the box body 1 and enhancing the connection stability between the support plate 5 and the side plate 6, this embodiment significantly improves the overall stability and load-bearing capacity of the protection device. This design not only protects the internal electrical connection components but also makes the device safer, more reliable, and easier to operate and maintain.

[0053] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
