Description

Technical Field

[0001] This utility model belongs to the field of switch cabinet technology, specifically relating to a warning device for frequency converter power switch cabinet. Background Technology

[0002] Switchgear is an important component of power systems, containing circuit breakers, disconnectors, load switches, operating mechanisms, instrument transformers, and various protection devices. The main function of switchgear is to open, close, control, and protect electricity during the power generation, transmission, distribution, and energy conversion processes of the power system.

[0003] When switchgear is de-energized, energized, or under maintenance, workers typically hang warning signs. However, existing switchgear warning signs often require the use of operating handles or other components for hanging. This not only makes it easy for the signs to become unstable and fall off, but also, because the signs are hung on the operating handles, they can obstruct the switchgear status display, thus affecting workers' ability to observe the switchgear's status.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a warning device for frequency converter power switch cabinets. Utility Model Content

[0005] The purpose of this utility model is to provide a warning device for frequency converter power switch cabinets to solve the problem that the switch cabinet signs are not easy to place.

[0006] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows: A warning device for a variable frequency power supply switchgear includes a switchgear body and a warning mechanism; The warning mechanism is attached to the main body of the switch cabinet. The warning mechanism includes a mounting frame with a magnet embedded in it. The magnet is attracted to the main body of the switch cabinet. The mounting frame has a warning groove with a sign inside. The side of the mounting frame away from the main body of the switch cabinet has a transparent plate corresponding to the sign. A pair of auxiliary adsorption mechanisms are also installed on the mounting frame.

[0007] Furthermore, the mounting frame is provided with a U-shaped groove, which is connected to the warning groove, making it convenient for staff to remove the sign from the warning groove for replacement, thereby improving the overall utilization rate of the warning mechanism.

[0008] Furthermore, the auxiliary adsorption mechanism includes a suction cup, which can be used to adhere to the main body of the switch cabinet, thereby further fixing the warning mechanism and making it less likely to detach from the main body of the switch cabinet, so that the warning sign in the warning slot can be used for warning. The suction cup is threaded onto the mounting frame, making it convenient for staff to replace the suction cup. The suction cup has a connecting cavity and a receiving cavity, which are connected to each other. When the suction cup is adsorbed onto the side wall of the switch cabinet body, the gas inside the suction cup is discharged through the connecting cavity and the receiving cavity to improve the adsorption effect between the suction cup and the side wall of the switch cabinet body.

[0009] Furthermore, the mounting frame is provided with a vent hole, which is connected to the receiving cavity, and the receiving cavity is connected to the outside through the vent hole.

[0010] Furthermore, the receiving cavity is provided with a sealing ball and a mesh frame. The sealing ball is engaged at the minimum diameter of the receiving cavity and is used to seal the connecting cavity. When the suction cup is adsorbed on the switch cabinet body, external gas is not easily allowed to enter the inside of the suction cup through the connecting cavity, thus ensuring the adsorption force between the suction cup and the switch cabinet body. The mesh frame is used to support the spring, so that the spring can apply force to the sealing ball.

[0011] Furthermore, a pull rope is connected to the blocking ball, one end of which passes through the mesh frame and the mounting frame. A linkage rope is connected between the pair of pull ropes. When the warning mechanism needs to be removed, the operator can pull the linkage rope to pull the pair of pull ropes, thereby causing both blocking balls to disengage from the connecting cavity. External gas enters the inside of the suction cup through the vent hole, the receiving cavity, and the connecting cavity, thereby reducing the suction force between the suction cup and the switch cabinet body, making it easier for the operator to remove the warning mechanism.

[0012] Furthermore, a spring is provided inside the receiving cavity. The spring is located outside the pull rope and between the blocking ball and the net frame. The spring is used to apply force to the blocking ball so that the blocking ball can block the connecting cavity in its natural state.

[0013] Compared with the prior art, the present invention has the following advantages: This utility model, through the design of a corresponding mechanism, facilitates the stable placement of switch cabinet labels by staff, preventing the labels from falling off. At the same time, it also prevents the labels from obstructing the switch cabinet status display, thus making it easier for staff to observe the status of the switch cabinet.

[0017] The utility model will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the utility model, and any transformations in structure, method or function made by those of ordinary skill in the art based on these embodiments are all included within the protection scope of the utility model.

[0018] The utility model discloses a warning device for a variable-frequency power switch cabinet, as shown in ref Figures 1-4 , comprising a switch cabinet main body 1 and a warning mechanism 2.

[0019] Wherein, the warning mechanism 2 is adsorbed on the switch cabinet main body 1. Compared with the manner that the warning mechanism 2 is suspended on components such as an operating handle, the warning mechanism 2 is less prone to falling off, and at the same time, the warning mechanism 2 is less likely to block the status display of the switch cabinet main body, so that the staff can observe the status of the switch cabinet main body conveniently.

[0020] As shown in ref Figures 1-4 , the warning mechanism 2 comprises a mounting frame 201, a magnet 202 is embedded on the mounting frame 201, the magnet 202 is adsorbed to the switch cabinet main body 1, and the mounting frame 201 can be adsorbed on the switch cabinet main body 1 by using the magnet 202, so as to realize the fixation of the warning sign and play a warning role.

[0021] Wherein, a warning slot 203 is arranged on the mounting frame 201, and a warning sign is arranged in the warning slot 203. The warning sign can be set as required, such as a "No Closing, People Are Working" warning sign, a "Work Here" warning sign, and the like.

[0022] In addition, a transparent plate 204 is disposed on the side of the mounting frame 201 facing away from the switch cabinet main body 1, and the transparent plate 204 corresponds to the sign, so that the content of the sign can be observed conveniently.

[0023] Specifically, the mounting frame 201 is provided with a U-shaped groove 205, which communicates with the warning groove 203, so that the staff can take out the sign from the warning groove 203 to replace the sign, and the overall utilization rate of the warning mechanism 2 is improved.

[0024] Ref Figures 1-4 As shown, a pair of auxiliary adsorption mechanisms are further mounted on the mounting frame 201. The auxiliary adsorption mechanism is used for auxiliary fixing of the warning mechanism 2, so that the warning mechanism 2 is not easy to fall off from the switch cabinet main body 1, and the stability of the sign during use is ensured.

[0025] Wherein, the auxiliary adsorption mechanism comprises a suction cup 206, which can be adsorbed on the switch cabinet main body 1, so as to realize further fixing of the warning mechanism 2, make the warning mechanism 2 not easy to separate from the switch cabinet main body 1, so that the sign in the warning groove 203 can be used for warning.

[0026] Preferably, the suction cup 206 is screwed to the mounting frame 201, which is convenient for the staff to replace the suction cup 206.

[0027] In addition, the suction cup 206 is internally provided with a communication cavity 207 and a containing cavity 208, and the communication cavity 207 communicates with the containing cavity 208. When the suction cup 206 is adsorbed on the side wall of the switch cabinet main body 1, the gas inside the suction cup 206 is discharged through the communication cavity 207 and the containing cavity 208, so as to improve the adsorption effect between the suction cup 206 and the side wall of the switch cabinet main body 1.

[0028] Specifically, the mounting frame 201 is provided with a vent hole, which communicates with the containing cavity 208, and the containing cavity 208 communicates with the outside through the vent hole.

[0029] Ref Figures 1-4 As shown, a blocking ball 209 and a grid frame 210 are disposed in the containing cavity 208, and the blocking ball 209 is engaged at the minimum diameter of the containing cavity 208. The blocking ball 209 is used for blocking the communication cavity 207. When the suction cup 206 is adsorbed on the switch cabinet main body 1, external gas is not easy to enter the inner side of the suction cup 206 through the communication cavity 207, so as to ensure the adsorption force between the suction cup 206 and the switch cabinet main body 1. The grid frame 210 is used for supporting the spring 212, so that the spring 212 can apply a acting force to the blocking ball 209.

[0030] Preferably, the blocking ball 209 is made of rubber material, so as to ensure the blocking effect of the blocking ball 209 on the communication cavity 207.

[0031] The blocking ball 209 is connected to a pull rope 211, one end of which passes through the mesh frame 210 and the mounting frame 201. A linkage rope 213 connects the two pull ropes 211. When the warning mechanism 2 needs to be removed, the operator can pull the pair of pull ropes 211 by pulling the linkage rope 213, which will cause both blocking balls 209 to disengage from the connecting cavity 207. External gas enters the inside of the suction cup 206 through the vent hole, the receiving cavity 208, and the connecting cavity 207, thereby reducing the suction force between the suction cup 206 and the switch cabinet body 1, making it easier for the operator to remove the warning mechanism 2.

[0032] Preferably, a pair of steering wheels are rotatably provided inside the mounting frame 201, and the pair of steering wheels correspond to a pair of pull ropes 211 respectively, so that the pull ropes 211 are not easy to rub against the side wall of the mounting frame 201 when being pulled, thus ensuring the service life of the pull ropes 211.

[0033] Additionally, a spring 212 is provided inside the receiving cavity 208. The spring 212 is located outside the pull rope 211 and between the sealing ball 209 and the mesh frame 210. The spring 212 is used to apply force to the sealing ball 209, so that the sealing ball 209 can seal the connecting cavity 207 in its natural state.

[0034] In practical use, when the sign is needed, first place the sign into the warning slot 203, then attach the magnet 202 to the switch cabinet body 1, thus achieving initial fixation of the mounting frame 201. When the magnet 202 attaches to the switch cabinet body 1, the suction cup 206 also comes into contact with the switch cabinet body 1. Pulling the linkage rope 213 causes the linkage rope 213 to pull the blocking ball 209 through the pull rope 211, causing the blocking ball 209 to disengage from the connecting cavity 207. Pressing the mounting frame 201 will compress the suction cup 206. At this time, the gas inside the suction cup 206 is discharged through the connecting cavity 207, the receiving cavity 208, and the vent hole, thereby improving the adhesion effect between the suction cup 206 and the switch cabinet body 1, making it less likely for the warning mechanism 2 to detach from the switch cabinet body 1.

[0035] If the sign needs to be replaced, simply remove the sign from the warning slot 203 and replace it with a new sign.

[0036] When the warning mechanism 2 needs to be removed, pull the linkage rope 213. The linkage rope 213, through the pull rope 211, pulls the blocking ball 209, causing the blocking ball 209 to disengage from the connecting cavity 207. At this time, external gas enters the inside of the suction cup 206 through the vent hole, the receiving cavity 208, and the connecting cavity 207, thereby reducing the attraction between the suction cup 206 and the switch cabinet body 1. Pull the mounting frame 201 to disengage the magnet 202 from the switch cabinet body 1.

[0037] As can be seen from the above technical solutions, this utility model has the following beneficial effects: This utility model, through the design of a corresponding mechanism, facilitates the stable placement of switch cabinet labels by staff, preventing the labels from falling off. At the same time, it also prevents the labels from obstructing the switch cabinet status display, thus making it easier for staff to observe the status of the switch cabinet.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
