Description

Technical Field

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

[0002] A circuit breaker is a switching device that can connect and disconnect not only normal load current and overload current, but also short-circuit current. In addition to its control function, a circuit breaker also provides certain protective functions in a circuit. Therefore, in the CNC machine tool industry, circuit breakers are used as the main switch for machine tools. However, industrial environments often contain significant amounts of oil mist, water mist, and dust. These substances can easily cause circuit breaker malfunctions, leading to equipment or personnel safety accidents. Therefore, when using a circuit breaker as the main switch, it is typically used in conjunction with a circuit breaker protective cover.

[0003] In related technologies, due to the complex assembly and operation of circuit breaker protective covers, a series of problems such as aging of the operating mechanism and decreased spring tension will occur as the service time increases, thus losing the function of protecting the circuit breaker.

[0004] Therefore, there is a market need for a circuit breaker protection device that is simple in structure, easy to install, and can be used for a long time in industrial environments. Utility Model Content

[0005] This application provides a circuit breaker protection device that can solve the problems of complex assembly and short service life in the prior art. The technical solution is as follows:

[0006] This utility model provides a circuit breaker protection device, including a connection structure and a protection structure.

[0007] The connecting structure includes a fixed plate, a mounting plate, a positioning plate, and a base plate. The mounting plate is vertically mounted on one end of the fixed plate, and the positioning plate is vertically mounted on the other end. The mounting plate is used to connect the electrical control box. A through groove is opened on the base plate, and positioning plates are set at both ends of the base plate. The positioning plates are detachably connected to the base plate. The protective structure includes a first baffle, a connecting plate, and a cover plate. The first baffle is vertically mounted on one side of the base plate and is located on the opposite side of the positioning plate. Connecting plates are set at both ends of the first baffle, and the cover plate is rotatably mounted on the connecting plate.

[0008] Furthermore, the protective structure also includes a second baffle and a surrounding plate. The second baffle is provided with surrounding plates at both ends. The second baffle and the surrounding plates are located on opposite sides of the positioning plate, and the bottom of the second baffle and the surrounding plates are connected to the wall of the through groove.

[0009] Furthermore, the connecting structure also includes a sliding baffle. The positioning plate is fixed relative to the base plate, and a sliding baffle is provided between the positioning plate and the base plate. The sliding baffle can slide relative to the base plate to partially close the through groove.

[0010] Furthermore, the protective structure also includes a rubber magnet, which is connected to the base plate. The rubber magnet can attract the cover plate to close it.

[0011] Furthermore, the protective structure also includes a padlock hook, which is located on one side of the rubber magnet and connected to the base plate. The padlock hook has a padlock hole, and the cover plate has a through hole. The padlock hook can pass through the through hole, and the padlock hole is used to lock the cover plate and the base plate together.

[0012] Furthermore, the protective structure also includes screws, a first connecting hole is opened on the cover plate, and a second connecting hole is opened on the base plate. The screws can pass through the first connecting hole and be threaded to the wall of the second connecting hole so that the cover plate is fixed to the base plate.

[0013] Furthermore, a first mounting hole is provided on the connecting plate, and a second mounting hole is provided on the cover plate. The first mounting hole and the second mounting hole are aligned, and the first mounting hole and the second mounting hole are used to install a rotating shaft so that the cover plate can rotate relative to the connecting plate.

[0014] The beneficial effects of the technical solutions provided in this application include at least the following:

[0015] A through slot is cut into the base plate, through which the circuit breaker and its switch pass. The cover plate can rotate, allowing it to open and close. When the cover plate is open, the circuit breaker and its switch are exposed for easy operation. When the cover plate is in contact with the base plate, it covers the circuit breaker and its switch, thus isolating them from oil and providing protection. Furthermore, under the influence of gravity, the cover plate remains normally closed, preventing oil mist, water mist, and dust from causing circuit breaker malfunctions.

[0016] The sliding baffle can slide along the length of the base plate to partially close the through slot, allowing the effective length of the through slot to be changed to accommodate circuit breakers with different numbers of pins. This makes the circuit breaker protection device adaptable to different types of circuit breakers, increasing its applicability.

[0032] like Figures 1 to 6 As shown, this utility model embodiment provides a circuit breaker protection device, including a connection structure 100 and a protection structure 200.

[0033] The connecting structure 100 includes a fixing plate 110, a mounting plate 120, a positioning plate 130, and a base plate 140. The mounting plate 120 is vertically mounted at one end of the fixing plate 110, and the positioning plate 130 is vertically mounted at the other end. The mounting plate 120 is used to connect the electrical control box. A through groove 142 is opened on the base plate 140, and the positioning plates 130 are provided at both ends of the base plate 140. The positioning plates 130 are detachably connected to the base plate 140. The protective structure 200 includes a first baffle 210, a connecting plate 220, and a cover plate 230. The first baffle 210 is vertically mounted on one side of the base plate 140 and is located on the opposite side of the positioning plate 130. The connecting plates 220 are provided at both ends of the first baffle 210, and the cover plate 230 is rotatably mounted on the connecting plate 220.

[0034] refer to Figure 1 and Figure 6 It should be noted that in this embodiment, the fixing plate 110 is a quasi-isosceles triangle structure. The top of the fixing plate 110 is connected to a mounting plate 120, and two positioning plates 130 are symmetrically arranged at the bottom of the fixing plate 110. The mounting plate 120 is threaded to the wall of the electrical control box, and the positioning plate 130 is threaded to the base plate 140. A through groove 142 is opened on the base plate 140. The two fixing plates 110 are symmetrically arranged on both sides of the base plate 140, and the circuit breaker and its switch pass through the through groove 142. A baffle is vertically installed on the top of the base plate 140. The first baffle 210 serves as the first layer of protection, and connecting plates 220 are installed at both ends of the first baffle 210. The connecting plates 220 are connected to the base plate 140. A cover plate 230 is installed on the connecting plates 220 and can rotate relative to the connecting plates 220, thus achieving an opening and closing effect. When the cover plate 230 is open, the circuit breaker and its switch are exposed, facilitating operation by personnel. When the cover plate 230 is in contact with the base plate 140, it covers the circuit breaker and its switch, thus isolating oil contaminants and achieving a protective effect for the circuit breaker. Furthermore, under the influence of gravity, the cover plate 230 remains normally closed.

[0035] In a further embodiment of this utility model, the entire circuit breaker protection device is made using sheet metal processing, and its surface is coated with protective powder, which can improve the service life and oil resistance of the circuit breaker protection device.

[0036] According to the circuit breaker protection device provided in the embodiment of this utility model, the protective structure 200 further includes a second baffle 240 and a surrounding plate 250. The surrounding plate 250 is provided at both ends of the second baffle 240. The second baffle 240 and the surrounding plate 250 are located on opposite sides of the positioning plate 130, and the bottom of the second baffle 240 and the surrounding plate 250 are both connected to the wall of the through groove 142.

[0037] It should be understood that, reference Figure 1 and Figure 5 The through slot 142 is located in the middle of the base plate 140. The positions of the second baffle 240 and the surrounding plate 250 are matched with the through slot 142. After installation, the second baffle 240 is located directly above the circuit breaker, and the surrounding plate 250 is located on both sides of the circuit breaker. The second baffle 240 and the surrounding plate 250 can serve as a second layer of protection to prevent oil mist and water mist from entering the circuit breaker and causing circuit breaker failure.

[0038] According to the circuit breaker protection device provided in the embodiment of this utility model, the connection structure 100 further includes a sliding baffle 150, the positioning plate 130 is fixed relative to the base plate 140, the sliding baffle 150 is provided between the positioning plate 130 and the base plate 140, and the sliding baffle 150 can slide relative to the base plate 140 to partially close the through groove 142.

[0039] It should be noted that in this embodiment, a first positioning hole 131 is provided on the positioning plate 130, and a second positioning hole 143 is provided on the base plate 140. The first positioning hole 131 and the second positioning hole 143 are aligned to achieve a threaded connection between the positioning plate 130 and the base plate 140. A sliding baffle 150 is provided between the positioning plate 130 and the base plate 140. A sliding groove 151 is provided on the sliding baffle 150. After the positioning plate 130 and the base plate 140 are fixed in position with bolts, the sliding baffle 150 can still slide along the length direction of the base plate 140 to partially close the through groove 142 to accommodate circuit breakers of different numbers. At the same time, the length of the sliding groove 151 is the maximum distance that the sliding baffle 150 can slide, thereby limiting the extreme position of the sliding baffle 150.

[0040] According to the circuit breaker protection device provided in the embodiment of this utility model, the protective structure 200 further includes a rubber magnet 260, which is connected to the base plate 140. The rubber magnet 260 can attract the cover plate 230 so that the cover plate 230 is closed.

[0041] refer to Figure 5It should be understood that the rubber magnet 260 can attract the cover plate 230. When the cover plate 230 needs to cover the circuit breaker and its switch, the cover plate 230 and the rubber magnet 260 are in contact, which ensures good fit between the cover plate 230 and the base plate 140, reduces the gap between the cover plate 230 and the base plate 140, and avoids circuit breaker failure caused by oil mist, water mist and dust.

[0042] According to the circuit breaker protection device provided in this embodiment of the present invention, the protective structure 200 further includes a padlock hook 270, which is disposed on one side of the rubber magnet 260 and connected to the base plate 140.

Simply passing the padlock through the padlock hole 271 will lock the cover plate 230 to the base plate 140. During equipment maintenance, after disconnecting the circuit breaker, locking the padlock will prevent other personnel from opening the cover plate 230, closing the circuit breaker, and energizing the equipment, thus preventing a safety accident.

[0044] According to the circuit breaker protection device provided in the embodiment of this utility model, the protective structure 200 further includes screws 280, a first connecting hole 232 is provided on the cover plate 230, a second connecting hole 141 is provided on the base plate 140, the screws 280 can pass through the first connecting hole 232 and be threadedly connected to the wall of the second connecting hole 141 so that the cover plate 230 is fixed to the base plate 140.

[0045] It should be noted that after screw 280 is tightened, cover plate 230 is fixed to base plate 140, ensuring that the circuit breaker protection device will not make any abnormal noise after installation. Loosening screw 280 during use makes it easier to open cover plate 230 for power disconnection in case of emergency.

[0046] According to the circuit breaker protection device provided in the embodiment of this utility model, a first mounting hole 221 is provided on the connecting plate 220, and a second mounting hole 233 is provided on the cover plate 230. The first mounting hole 221 and the second mounting hole 233 are aligned, and the first mounting hole 221 and the second mounting hole 233 are used to install a rotating shaft so that the cover plate 230 can rotate relative to the connecting plate 220.

[0047] It should be noted that when the first mounting hole 221 and the second mounting hole 233 are aligned, the rotating shaft is inserted, allowing the cover plate 230 to rotate around the rotating shaft. When the cover plate 230 rotates upward, the through groove 142 is exposed, thereby exposing the circuit breaker and its switch. When the cover plate 230 rotates to fit against the rubber magnet 260, the cover plate 230 covers the circuit breaker and its switch to protect the circuit breaker.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
