Description

Technical Field

[0001] This utility model belongs to the field of switch protection technology, specifically relating to a relay safety protection device for switch cabinets. Background Technology

[0002] Relay safety protection for switchgear is a crucial measure to ensure the safe operation of switchgear and power equipment in a power system. This includes overcurrent protection devices, short-circuit protection devices, grounding protection devices, and overvoltage protection devices. Therefore, relay safety protection for switchgear is of great significance for ensuring the safe and stable operation of the power system.

[0003] Currently, the relay safety protection of switchgear is typically an automated measure and device that can promptly issue warning signals to operating personnel or directly issue trip commands to the controlled circuit breakers to terminate these events. However, such control and protection devices lack adequate protective functions, making the switches on the protection device prone to accidental activation or the display screen prone to wear, thereby reducing the service life of the device. Furthermore, they are prone to sending incorrect signals to personnel, causing unnecessary trouble for users.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a relay safety protection device for switchgear.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this utility model is to provide a relay safety protection device for switchgear, which can solve the problem of lack of protection in the safety controller of switchgear in the prior art.

[0007] To achieve the above objectives, a specific embodiment of this utility model provides a relay safety protection device for a switchgear, comprising: a relay control box and a protective mechanism;

[0008] Multiple support plates are fixedly installed on the relay control box;

[0009] The protective mechanism is installed on one side of the relay control box. The protective mechanism includes a protective cover with a transparent cover. A pair of connecting bolts are fixedly connected to one side of the protective cover. A rotating support shaft is fixedly installed on each of the connecting bolts. The two ends of the rotating support shaft are rotatably connected to a pair of support plates. One end of one of the rotating support shafts has a limit square hole. A pair of connecting rods are also inserted into the protective cover. At both ends of the pair of connecting rods are fixedly connected to an attraction block.

[0010] In one or more embodiments of this utility model, a pair of fixed insertion holes are drilled on the relay control box to provide space for inserting the attraction block. A magnetic block is fixedly installed in each of the pair of fixed insertion holes. The attraction block is attracted by the magnetic block, so that the protective cover is not easy to shake, thereby improving the protection of the relay control box.

[0011] In one or more embodiments of this utility model, the relay control box is provided with a display screen and multiple control buttons for convenient observation of equipment parameters and control of the equipment.

[0012] In one or more embodiments of this utility model, the protective cover is equipped with a handle for easy pulling and rotating of the protective cover, making it convenient to operate.

[0013] In one or more embodiments of this utility model, a limiting pin is inserted into the support bar plate to support the fixed rod and drive the fixed rod to move. A fixed rod matching the limiting square hole is fixedly installed at one end of the limiting pin near the rotating support shaft. By inserting the fixed rod into the limiting square hole, the protective cover cannot rotate, thereby achieving the effect of fixing.

[0014] In one or more embodiments of this utility model, a connecting block is fixedly connected to the end of the limiting pin away from the rotating support shaft for easy pulling. A connecting spring is fixedly connected between the connecting block and the support bar for pulling the connecting block, thereby pushing the limiting pin and driving the fixed plug rod to be inserted into the limiting square hole on the rotating support shaft, thus making the protective cover less likely to rotate.

[0015] In one or more embodiments of this utility model, the cross-section of the fixing rod is square, so that the protective cover is not easily rotated after the fixing rod is inserted into the limiting square hole.

[0016] In one or more embodiments of this utility model, the attraction block is made of iron sheet, which facilitates the attraction of the magnetic block.

[0017] Compared with the prior art, this utility model adds safety protection to the switch cabinet control device through the setting of corresponding mechanisms, making the buttons less likely to be accidentally touched and the display screen less likely to be worn, thereby increasing the service life of the device, and avoiding sending wrong signals to the staff, reducing unnecessary trouble for the user.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, 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, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1 to 6As shown, a relay safety protection device for a switchgear according to one embodiment of the present invention includes: a relay control box 1 and a protection mechanism 2.

[0029] like Figures 1 to 3 As shown, multiple support plates 101 are fixedly installed on the relay control box 1 to support the rotating support shaft 203, making it less likely to fall off while allowing it to rotate. A pair of fixing holes 102 are drilled on the relay control box 1 to provide space for inserting the attraction block 206. A magnet 103 is fixedly installed in each of the fixing holes 102, attracting the attraction block 206 and preventing the protective cover 201 from shaking, thus improving the protection of the relay control box 1.

[0030] The relay control box 1 is equipped with a display screen 104 and multiple control buttons 105 for convenient observation of equipment parameters and control of the equipment.

[0031] like Figures 1 to 6 As shown, the protective mechanism 2 is installed on one side of the relay control box 1. The protective mechanism 2 includes a protective cover 201, which is used to protect the relay control box 1, making it less susceptible to damage, reducing the probability of damage to the display screen 104, and preventing accidental activation of the multiple control buttons 105. A transparent cover 204 is installed on the protective cover 201 for easy observation by the staff. A pair of connecting bolts 202 are fixedly connected to one side of the protective cover 201. A rotating support shaft 203 is fixedly installed on each of the pair of connecting bolts 202. The two ends of the rotating support shaft 203 are rotatably connected to a pair of support plates 101 respectively.

[0032] Specifically, one end of one of the rotating support shafts 203 has a limiting square hole, and a pair of connecting rods 205 are inserted into the protective cover 201. Attracting blocks 206 are fixedly connected to both ends of the pair of connecting rods 205. The attracting blocks 206 are made of iron sheets to facilitate the attraction of the magnetic block 103.

[0033] like Figures 1 to 6 As shown, a handle 207 is installed on the protective cover 201 for easy rotation and operation. A limiting pin 208 is inserted into the support plate 101 to support and move the fixing rod 209. A fixing rod 209 matching the limiting square hole is fixedly installed at one end of the limiting pin 208 near the rotating support shaft 203. By inserting the fixing rod 209 into the limiting square hole, the protective cover 201 cannot rotate, thus achieving a fixed effect. The cross-section of the fixing rod 209 is square, making it difficult for the protective cover 201 to rotate after the fixing rod 209 is inserted into the limiting square hole.

[0034] like Figures 1 to 6As shown, a connecting block 210 is fixedly connected to the end of the limiting pin 208 away from the rotating support shaft 203 for easy pulling. A connecting spring 211 is fixedly connected between the connecting block 210 and the support strip 101 for pulling the connecting block 210, thereby pushing the limiting pin 208 and driving the fixed insert 209 to be inserted into the limiting square hole on the rotating support shaft 203, thus making the protective cover 201 less likely to rotate.

[0035] In practical use, when it is necessary to operate the relay control box 1, first pull the connecting block 210. The connecting block 210 drives the limit pin 208 and the fixed rod 209 to move, so that the fixed rod 209 is no longer stuck in the limit square hole on the rotating support shaft 203. At this time, pull the handle 207 to drive the protective cover 201 to rotate, thereby exposing the display screen 104 and multiple control buttons 105. Then, after rotating the protective cover 201 by 90 degrees, release the connecting block 210, so that the connecting spring 211 pulls the connecting block 210 back to its original position, thereby pushing the limit pin 208 to drive the fixed rod 209 to be inserted into the limit square hole on the rotating support shaft 203 again. At this time, the rotating support shaft 203 will not be able to rotate, thereby achieving the effect of fixing the protective cover 201, which makes it convenient for the staff to operate.

[0036] After use, first pull the connecting block 210 to remove the fixing rod 209 from the limiting square hole. Then rotate the protective cover 201 onto the relay control box 1. At this time, the magnetic block 103 attracts the attracting block 206, making the protective cover 201 less prone to shaking. Then release the connecting block 210 so that the fixing rod 209 can be inserted into the limiting square hole again, thus fixing the protective cover 201.

[0037] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
