Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, and particularly relates to a low-voltage chamber panel and a switch cabinet. Background Technique

[0002] The switch cabinet is one of the key devices in the power system, mainly used for the control, protection, distribution and monitoring of the power system. It is a cabinet integrating various electrical devices, used to receive and distribute electric energy, and can perform necessary control and protection operations on the circuit. According to the voltage level, it can be divided into low-voltage switch cabinets, medium-voltage switch cabinets and high-voltage switch cabinets. Among them, the low-voltage switch cabinet mostly adopts a draw-out structure for easy maintenance, and the drawer panel of the draw-out structure is mostly installed inside the switch cabinet by means of hinges and connected to the inner side of the drawer door. In this installation method, when the drawer door is opened, the door panel and the cabinet side plate will collide, so that the door panel can only be opened to 90°, and the opening angle is small, which brings unnecessary trouble to the installation of electrical components.

[0003] In the prior art, there is research on the small opening angle of the drawer panel installed by hinges. For example, in the patent application CN204030403U - Drawer of Low-Voltage Draw-Out Switch Cabinet, the drawer panel is installed on the drawer body through an outer buckle cover and a mounting bracket, which solves the problem of the small opening angle of the current drawer panel installed by hinges. Although the existing drawer panel can increase the opening angle, it is very difficult to effectively control the stability after the panel is opened, thus seriously affecting the installation and maintenance efficiency of electrical components. Therefore, a new technical solution is needed to solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a low-voltage chamber panel and a switch cabinet to solve the problems that at the present stage, it is very difficult to effectively control the stability after the panel is opened, thus seriously affecting the installation and maintenance efficiency of electrical components and other problems mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A low-voltage chamber panel includes a panel body. At both ends of the rear side of the panel body, a bracket is fixed respectively. The two brackets move in the guiding grooves opened at both ends of the front side of the low-voltage chamber respectively. On the rear side walls of the two guiding grooves, a rivet pin A and a rivet pin B are abutted respectively. The rivet pin A and the rivet pin B penetrate and are fixed at the ends of the two brackets respectively. The panel body is limited and movable at the front side of the low-voltage chamber through the two brackets, the rivet pin A, the rivet pin B and the two guiding grooves.

[0006] Further, the two brackets are respectively set as bracket A moving in the guiding groove at one end of the front side of the low-voltage chamber and bracket B moving in the guiding groove at the other end of the front side of the low-voltage chamber. Bracket B is mirror-symmetrically arranged relative to the panel body with respect to bracket A.

[0007] Further, one end of the bracket A is fixed on the inner side wall at one end of the rear side of the panel body. An inclined surface A is provided at the upper part of the other end of the bracket A, and the lower part of this end is fixedly connected through the rivet pin A in a penetrating manner; one end of the bracket B is fixed on the inner side wall at the other end of the rear side of the panel body. An inclined surface B is provided at the upper part of the other end of the bracket B, and the lower part of this end is fixedly connected through the rivet pin B in a penetrating manner; the rivet pin B is arranged opposite to the rivet pin A with respect to the panel body. The rivet pin A and the rivet pin B are respectively limited and abutted against the rear side walls of the two guide grooves through the bracket A and the bracket B; the front side walls of the two guide grooves are respectively in a limiting contact connection with the panel body through the bracket A and the bracket B. One guide post lower than the inner side height of the guide groove is arranged in parallel on each outer side of the two guide grooves, and the two guide posts are respectively in a limiting movable connection with the bracket A and the bracket B; the bracket A is suspended between the inner side of one guide groove and the inner side of the guide post arranged in parallel with the outer side of this guide groove through the inclined surface A and the rivet pin A; the bracket B is suspended between the inner side of the other guide groove and the inner side of the guide post arranged in parallel with the outer side of this guide groove through the inclined surface B and the rivet pin B.

[0008] Further, the panel body is limited and suspended at the front side of the low-voltage chamber through the rivet pin A and the rivet pin B arranged opposite to each other, the bracket A and the bracket B arranged in a mirror image, and the two guide grooves.

[0009] In addition to the above technical solutions, there is also a switch cabinet with the panel of the low-voltage chamber.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The present utility model adopts the setting of the movable connection between the bracket and the guide groove, so that the panel body can be translated to open or close along with the movement of the bracket without considering the opening angle, effectively avoiding the problem that the installation or maintenance of electrical components is affected by the size of the opening angle. By using the limiting effect of the rivet pin A and the rivet pin B, the panel body can be stably and firmly suspended at the front side of the low-voltage chamber after being opened, effectively avoiding the problem that the connecting wires of electrical components are affected by the change of the opening angle, effectively reducing the workload of arranging the connecting wires of electrical components, so that the stability of the panel body after being opened is effectively controlled, ensuring the installation and maintenance efficiency of electrical components, and at the same time effectively avoiding the risk of the panel body slipping or falling after being opened, ensuring the safety of the panel body when it is opened.

[0025] The following embodiments are used to further illustrate the content of the present utility model and do not limit the application of the present utility model. Embodiment 1:

[0026] Please refer to Figures 1 - 9 , this embodiment provides a low-voltage chamber panel, including a panel body 1 for ensuring the safe operation of the low-voltage chamber. At both ends of the rear side of the panel body 1, a bracket for driving the movement of the panel body 1 is fixed respectively. The two brackets move in guide grooves 3 opened at both ends of the front side of the low-voltage chamber 2 and used for providing a moving track for the brackets. On the rear side walls of the two guide grooves 3, a rivet pin A 4 and a rivet pin B 5 for limiting the movement of the brackets are respectively abutted. The rivet pin B 5 is arranged opposite to the rivet pin A 4 with respect to the panel body 1. The rivet pin A 4 and the rivet pin B 5 respectively penetrate and are fixed at the ends of the two brackets. The panel body 1 is limited and movable on the front side of the low-voltage chamber 2 through the two brackets, the rivet pin A 4, the rivet pin B 5 and the two guide grooves 3.

[0027] Please refer to Figures 1 - 8 , the two brackets are respectively a bracket A 6 moving in the guide groove 3 at one end of the front side of the low-voltage chamber 2 and a bracket B 7 moving in the guide groove 3 at the other end of the front side of the low-voltage chamber 2. The bracket B 7 is arranged mirror-symmetrically with respect to the panel body 1 and the bracket A 6;

[0028] One end of the bracket A 6 is fixed on the inner side wall of one end of the rear side of the panel body 1. At the upper part of the other end of the bracket A 6, an inclined plane A 8 for changing the opening position of the panel body 1 is provided, and the lower part of this end is fixedly connected with the rivet pin A 4 through penetration;

[0029] One end of the bracket B 7 is fixed on the inner side wall of the other end of the rear side of the panel body 1. At the upper part of the other end of the bracket B 7, an inclined plane B 9 for changing the opening position of the panel body 1 is provided, and the lower part of this end is fixedly connected with the rivet pin B 5 through penetration;

[0030] The rivet pins A4 and B5 are respectively limited and abutted against the rear side walls of the two guide grooves 3 through the brackets A6 and B7. The front side walls of the two guide grooves 3 are respectively in limiting contact connection with the panel body 1 through the brackets A6 and B7. The panel body 1 is suspended in front of the low-voltage chamber 2 through the oppositely arranged rivet pins A4 and B5, the mirror-image arranged brackets A6 and B7, and the two guide grooves 3, so that the space of the low-voltage chamber 2 can be completely exposed when the panel body 1 is opened to the suspended state, and then the electrical components in the space of the low-voltage chamber 2 can be installed or repaired.

[0031] Please refer to Figures 1 - 4 , on the outer side of each of the two guide grooves 3, a guide post 10 which is lower than the inner side of the guide groove 3 and is used for guiding and limiting is arranged in parallel, and the brackets A6 and B7 are respectively in limiting movable connection with the two guide posts 10;

[0032] The bracket A6 is suspended between the inner side of one of the guide grooves 3 and the inner side of the guide post 10 arranged in parallel with the outer side of the guide groove 3 through the inclined plane A8 and the rivet pin A4;

[0033] The bracket B7 is suspended between the inner side of the other guide groove 3 and the inner side of the guide post 10 arranged in parallel with the outer side of the guide groove 3 through the inclined plane B9 and the rivet pin B5.

[0034] The working principle and use process of this embodiment: As Figures 1 - 9 shown, after the low-voltage chamber panel is completed, the operator can install the whole low-voltage chamber panel on the front side of the low-voltage chamber 2 of the switch cabinet 11, which can solve the problems of affecting the installation or repair of electrical components and the connecting wires of electrical components due to the opening angle, reduce the workload of arranging the connecting wires of electrical components, and effectively improve the safety of opening the panel body 1 at the same time, so that the stability of the panel body 1 after opening is effectively controlled, and the installation and repair efficiency of electrical components is guaranteed.

[0035] When electrical components need to be installed or repaired in the low-voltage chamber 2 of the switch cabinet 11, in order to facilitate the opening of the panel body 1, a handle will be installed at a suitable position of the panel body 1 (the functions and structures of conventional devices such as handles are well known in the art, and the connection settings are also common knowledge, so no more description will be given here and it is not shown in the drawings). The operator will use the handle to move the panel body 1 from the closed state (i.e., the position clamped on the front side of the low-voltage chamber 2, such as Figure 9It is changed to the open state (as shown in the figure), that is, the operator pulls out the panel body 1 through the handle. At this time, the bracket A6 and the bracket B7 will move from the rear side of the guide groove 3 to the front side of the guide groove 3 (i.e., move forward) respectively during the process of pulling out the panel body 1 until the rivet pin A4 on the bracket A6 and the rivet pin B5 on the bracket B7 abut against the rear side wall of the guide groove 3. Then, by using the slopes of the inclined plane A8 on the bracket A6 and the inclined plane B9 on the bracket B7, the bracket A6 and the bracket B7 move downward, so that the panel body 1 can be suspended on the front side of the low-voltage chamber 2 (such as Figure 1 shown). The space in the low-voltage chamber 2 will be completely exposed, and then the electrical components are installed in the low-voltage chamber 2 or the electrical components in the low-voltage chamber 2 are repaired;

[0036] After the installation or repair of the electrical components is completed, the operator changes the panel body 1 from the open state (i.e., the position suspended on the front side of the low-voltage chamber 2, such as Figure 1 shown) to the closed state. Before the panel body 1 is closed, it is necessary to change the panel body 1 from the suspended position to the horizontal position, that is, the operator uses the handle to lift the panel body 1 upward by using the slopes of the inclined plane A8 on the bracket A6 and the inclined plane B9 on the bracket B7, so that the bracket A6 and the bracket B7 move upward, so that the panel body 1 is in the horizontal position. Then, the panel body 1 is pushed backward. At this time, the bracket A6 and the bracket B7 move from the front side of the guide groove 3 to the rear side of the guide groove 3 (i.e., move backward), and the rivet pin A4 on the bracket A6 and the rivet pin B5 on the bracket B7 will move away from the rear side wall of the guide groove 3 until the panel body 1 is clamped at the position on the front side of the low-voltage chamber 2 (such as Figure 9 shown). Embodiment 2:

[0037] Please refer to Figures 1 - 9 . As another object of the present utility model, a switch cabinet is provided. The above low-voltage chamber panel is provided in the switch cabinet 11. Therefore, the switch cabinet 11 can obtain any beneficial effects possessed by the above-described low-voltage chamber panel, which will not be elaborated here.
