Description

Technical Field

[0001] This utility model belongs to the field of electrical protection technology, and in particular relates to a protective device for industrial equipment. Background Technology

[0002] In modern industrial production, industrial control cabinets, as the core control units of electrical equipment, are widely used in various fields. With the continuous development of industrial technology, the protection level of control cabinets has become relatively mature under normal conditions. For example, the common IP protection level system can effectively prevent a certain degree of dust intrusion and water splashes.

[0003] However, in some special production environments, the existing electrical cabinet protection measures are clearly insufficient. Taking a carbon fiber production workshop as an example, a large number of fine carbon fiber filaments are generated during the production process. These carbon fiber filaments have good conductivity. In addition, in some environments where there is conductive dust or particulate matter in the air, when the door of the industrial control electrical cabinet is opened or air is introduced through the air inlet, these conductive foreign objects can easily enter the cabinet with the airflow. Once foreign objects such as carbon fiber filaments or conductive dust enter the cabinet, they are very likely to break down the power system, causing the cabinet to malfunction, which in turn affects the normal operation of the entire production line, resulting in serious consequences such as production stoppage, equipment damage, and economic losses.

[0004] Currently, although various types of industrial electrical cabinets exist on the market, there is a severe lack of protective devices specifically designed to prevent foreign objects from entering the power system when the cabinet is open or when the air conditioning intake is exposed. Traditional electrical cabinets only have a certain design for overall sealing and protection, and cannot effectively prevent foreign objects from entering when the cabinet is opened for maintenance, repair, or other operations, making it difficult to meet the needs of special production environments.

[0005] Therefore, there is an urgent need to design an industrial equipment protection device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an industrial equipment protection device that effectively blocks foreign objects in the air and solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model for an industrial equipment protection device is as follows: An industrial equipment protection device is disclosed. The industrial equipment includes a cabinet with an air inlet and an opening after the cabinet door is opened. The protection device includes a first protection component and a second protection component. The first protection component is installed on the air inlet and / or the opening and intercepts foreign objects in the air. A wire hole is provided on the first protection component for wires to pass through. The second protection component is located in the wire hole so that foreign objects can be intercepted during wire routing.

[0008] Furthermore, the first protective component includes a protective net and a support frame. The protective net is fixedly connected to the support frame, which intercepts foreign objects in the air. The support frame is connected to the air inlet and / or opening.

[0009] Furthermore, a slot is provided at the air inlet, and a bracket is inserted into the slot to cover the air inlet with a protective net.

[0010] Furthermore, the bracket is embedded in the opening, so that the protective net covers the opening, and the opening fits against the first protective component.

[0011] Furthermore, the protective netting is made of polyamide and has a 300-mesh specification.

[0012] Furthermore, the cable passage hole is located on the bracket at the opening, allowing the cable to pass through the cable passage hole from the outside of the cabinet to the inside of the cabinet.

[0013] Furthermore, the second protective component includes a first protective element and a second protective element. The first protective element is connected to the outside of the cable passage hole, and the second protective element is connected to the inside of the cable passage hole. When the cable passes through the cable passage hole, the double protection provided by the first and second protective elements helps to intercept foreign objects.

[0014] Furthermore, a first gap is provided between the first protective component and the second protective component to form a buffer layer.

[0015] Furthermore, the first protective component includes a grid physical barrier connected to the outside of the cable passage hole. During cable passage, the cable passes through the gaps in the grid physical barrier and extends to the buffer layer.

[0016] Furthermore, the second protective component includes a sealing ring, which is connected to the inside of the cable passage hole. When the cable passes through the buffer layer, it passes through the sealing ring and extends into the cabinet.

[0017] This utility model has the following advantages: by deploying the first protective component simultaneously at the cabinet opening and the air inlet, it fills the protection gap when opening and maintaining the traditional electrical cabinet. When it is necessary to maintain, repair or upgrade the equipment inside the electrical cabinet, the operator can directly operate the cable through the cable hole without opening the first protective component. At the same time, the second protective component protects the cable hole to prevent foreign objects from entering the cabinet. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0021] The following is a reference to the appendix. Figure 1 To be continued Figure 7 This utility model describes an industrial equipment protection device. The industrial equipment includes a cabinet 1. The cabinet 1 is provided with an air inlet 12 and an opening 13 after opening the cabinet door 11. Specifically, the air inlet 12 is an air conditioning inlet 12. When air flows, whether it enters through the air conditioning inlet 12 or through the opening 13 of the cabinet 1 after opening the cabinet door 11, foreign particles carried in the air will enter the interior of the cabinet 1.

[0022] Currently, although various types of industrial electrical cabinets exist on the market, there is a severe lack of protective devices specifically designed to prevent foreign objects from entering the power system when the cabinet is open and at the air conditioning inlet 12. Traditional electrical cabinets only have a certain design for overall sealing protection, and cannot effectively prevent foreign objects from entering when the cabinet is opened for maintenance, repair and other operations, making it difficult to meet the needs of special production environments.

[0023] Therefore, this industrial equipment protective device includes a first protective component 2 and a second protective component 4. The first protective component 2 is installed on the air inlet 12 and / or the opening 13. The first protective component 2 intercepts foreign objects in the air. The first protective component 2 has a wire hole 3 for wires to pass through. The second protective component 4 is located in the wire hole 3 so that foreign objects can be intercepted during wire routing. Specifically, the first protective component 2 can be installed on the air inlet 12 or the opening 13. The first protective component 2 can be installed on both the air inlet 12 and the opening 13.

[0024] By simultaneously deploying the first protective component 2 at the opening 13 and the air inlet 12 of the electrical cabinet, the protective gap during the traditional opening and maintenance of electrical cabinets is filled. When maintenance, repair or upgrade of the equipment inside the electrical cabinet is required, the operator can directly operate the cables through the cable hole 3 without opening the first protective component 2, which greatly improves the efficiency of maintenance and repair, reduces the risk of foreign object intrusion caused by frequent opening of the protective net 21, and provides a more reliable guarantee for the safe and stable operation of the electrical cabinet.

[0025] The first protective component 2 includes a protective net 21 and a bracket 22. The protective net 21 is fixedly connected to the bracket 22. The protective net 21 intercepts foreign objects in the air, and the bracket 22 is connected to the air inlet 12 and / or opening 13. By installing the protective net 21 on the bracket 22, a complete protective structure is formed. The robust structure of the bracket 22 can support the protective net 21, so that it will not be deformed or damaged by external forces during long-term use, thus ensuring the continuous effectiveness of the protective function.

[0026] Specifically, the protective net 21 is made of polyamide, which has high strength, wear resistance, and corrosion resistance. It can adapt to various harsh conditions in industrial production environments, ensuring that the protective net 21 will not be damaged by environmental factors during long-term use, thus continuously playing a protective role. The protective net 21 is 300 mesh, which means there are 300 mesh openings per square inch. The mesh size is precisely calculated to effectively intercept foreign particles of various sizes, including fine carbon fiber filaments and conductive dust. Since the mesh size of the protective net 21 is smaller than most foreign particles, the particles cannot pass through the mesh and are intercepted on the outside of the protective net 21, achieving the core protection requirement of 100% interception of foreign particles and preventing these foreign objects from entering the electrical cabinet and threatening the power system.

[0027] Specifically, the bracket 22 is made of 304 stainless steel. 304 stainless steel has good corrosion resistance, strength and toughness, can maintain the stability of the structure for a long time in industrial environment, and is not easy to rust, ensuring the durability of the protective frame. The first protective component 2 at the opening 13, the bracket 22, is precisely designed according to the size and shape of the cabinet door 11, so that it can fit tightly against the cabinet door 11.

[0028] When the first protective component 2 is installed with the air inlet 12, a slot 14 is provided at the air inlet 12. The bracket 22 is inserted into the slot 14 so that the protective net 21 covers the air inlet 12.

[0029] When the first protective component 2 is installed with the opening 13, the bracket 22 is embedded in the opening 13, so that the protective net 21 covers the opening 13, and the opening 13 fits snugly with the first protective component 2. The embedded installation method ensures that there is no gap between the protective net 21 and the electrical cabinet, eliminating the possibility of foreign objects entering the electrical cabinet from the installation location, and achieving a protection effect without dead angles or loopholes. Specifically, protective mounting brackets 22 are added all around the opening 13 of the cabinet 1. The brackets 22 of the first protective component 2 are embedded to ensure a seamless connection with the original electrical cabinet door 11 and the protective net 21.

[0030] The cable passage hole 3 is opened on the bracket 22 at the opening 13, so that the cable can pass through the cable passage hole 3 from the outside of the cabinet 1 to the inside of the cabinet 1. Preferably, the diameter of the cable passage hole 3 is 40mm to meet the needs of the internal equipment of the electrical cabinet and the external connection cable. In other embodiments of this utility model, the cable passage hole 3 can also be other sizes, as long as it can meet the needs of the cable to pass through.

[0031] The second protective component 4 includes a first protective element 41 and a second protective element 42. The first protective element 41 is connected to the outside of the cable passage hole 3, and the second protective element 42 is connected to the inside of the cable passage hole 3. When the cable passes through the cable passage hole 3, the double protection of the first protective element 41 and the second protective element 42 is used to intercept foreign objects. The second protective element 42 is tightly fitted to the cable to prevent foreign objects from entering through the gap between the cable and the second protective element 42. The first protective element 41 provides additional protection to further enhance the protective effect.

[0032] A first gap is provided between the first protective member 41 and the second protective member 42 to form a buffer layer 43. Through the buffer layer 43, foreign objects penetrating the first protective member 41 are slowed down in the buffer layer 43 and cannot cross the first gap to reach the second protective member 42. This can effectively block foreign objects from entering the electrical cabinet through the wire hole 3. Preferably, the first gap is 15mm so that foreign objects penetrating the first protective member 41 are slowed down in the 15mm gap. In other embodiments of this utility model, the first gap can also be other distances, as long as it can ensure that foreign objects are slowed down in the gap and cannot reach the second protective layer.

[0033] The first protective component 41 includes a grid physical barrier, which is connected to the outside of the wire passage hole 3. When the wire passes through, the cable passes through the gap in the grid physical barrier and extends to the buffer layer 43. By setting the grid physical barrier, 99% of the common conductive fiber clumps in the workshop can be directly blocked. Moreover, the sharp edge of the grid physical barrier cuts the airflow, disrupts the laminar flow state, and causes foreign objects to settle due to gravity.

[0034] The second protective component 42 includes a sealing ring, which is connected to the inside of the cable passage hole 3. When the cable passes through the buffer layer 43, it passes through the sealing ring and extends into the cabinet 1. Specifically, the sealing ring is made of fluororubber to accommodate cables with a diameter of 30-50mm.

[0035] The beneficial effects of this utility model are: (1) High protection performance: By setting the first protection component 2 at the air inlet 12 and the cabinet 1 inlet 13, it can intercept foreign particulate matter 100%, effectively prevent foreign objects such as carbon fiber filaments and conductive dust from entering the cabinet and breaking down the power system, greatly improving the protection capability of the industrial control cabinet in special production environments, ensuring the safe and stable operation of the cabinet and related equipment, reducing equipment failures and downtime caused by foreign object intrusion, and improving production efficiency.

[0036] (2) Structural stability and durability: The bracket 22, made of 304 stainless steel, has good corrosion resistance, strength and toughness, and can be used stably for a long time in industrial environment. It is not easy to deform or be damaged. The embedded installation method realizes the seamless connection between the protective net 21 and the electrical cabinet, ensuring that there are no dead angles or loopholes in the protection, extending the service life of the protective device and reducing maintenance costs.

[0037] (3) Convenience of maintenance: The design of the second protective component 4 and the wire hole 3 allows for maintenance, repair and upgrade of the equipment inside the electrical cabinet without opening the protective net, which improves the efficiency of maintenance work and reduces the risk of foreign objects entering due to opening the first protective component 2.

[0038] (4) Wide Applicability: The design concept and structure of this protective device are suitable for a variety of special production environments, such as workshops with conductive dust and particulate matter, as well as other industrial sites with high protection requirements. Whether it is a newly manufactured industrial control cabinet or an upgrade of an existing cabinet, it can be easily installed and used, and has a wide market application prospect.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
