Description

Technical Field

[0001] This utility model relates to the field of substation equipment technology, specifically to a housing for a smart substation secondary safety measure verification instrument. Background Technology

[0002] Currently, with the continuous development of smart grids, smart substations, as a key component, undertake important tasks of power transmission, distribution, and control. The stable operation of substations is crucial to the reliability and safety of the power system. In the daily operation, maintenance, and equipment repair of substations, the formulation and implementation of secondary safety measures tickets is a critical link. Secondary safety measures tickets are mainly used to guide the safe operation of secondary equipment, including the implementation of a series of safety measures such as power outages, voltage testing, and grounding of relay protection devices, automatic control systems, and communication equipment. This ensures the safety and reliability of the operation of secondary equipment in substations, thereby better guaranteeing the stable operation of smart substations and improving the operation and maintenance management level of the entire power system.

[0003] Chinese utility model patent CN223123209U discloses a handheld one-button safety measure verification device for intelligent substations, which includes "a housing and a control board disposed within the housing, the housing comprising an upper shell and a bottom shell connected to the upper shell, the upper shell having a human-machine interface, the bottom shell having a lithium battery, the lithium battery being connected to the control board via a charging and discharging control board, the charging and discharging control board being electrically connected to a charging interface at the bottom of the housing; the control board also includes a processor for executing computer binary code and an alarm module electrically connected to the processor for sending sound or optical alarms, a storage unit for temporarily storing SCD configuration files, a data interface for collecting data, and a communication module for communicating with the station control layer monitoring system";

[0004] This device can monitor and verify safety measures online, detect abnormalities, and issue timely alarms to prevent unnecessary safety accidents.

[0005] Substations are often built in remote, rural areas, where the environment is complex and there are many electrical devices, resulting in concentrated heat, especially in hot weather. However, the casing of the device lacks ventilation holes and heat dissipation structures, and the connectors are easily pulled by external forces when the device's interface is plugged in, causing damage to the device interface and making it impractical. Utility Model Content

[0006] The purpose of this utility model is to provide a housing for a smart substation secondary safety measure verification instrument to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a housing for a smart substation secondary safety measure verification instrument, comprising an outer shell, wherein ventilation holes are provided on both sides of the outer shell;

[0008] A cooling fan is installed inside the bottom surface of the outer casing, and a dustproof baffle is provided on the bottom surface of the cooling fan;

[0009] Multiple sets of fixing components are fixedly connected inside the side wall of the outer shell.

[0010] The beneficial effects of this utility model are as follows: This device has a cooling fan installed on the bottom surface of the outer shell, and ventilation holes are opened on both sides of the outer wall of the outer shell. The cooling fan draws the air inside the outer shell out and discharges it through the heat dissipation port, while the cold air outside enters through the ventilation holes on both sides, so that the air inside the outer shell circulates and achieves the effect of ventilation and heat dissipation.

[0011] With the fixing components in place, the external plug is inserted through the through hole into the round hole between the first and second arc-shaped clamps, allowing the plug to pass through the fixing shell and connect to the device's connector. During this process, as the plug is inserted, it presses against the first and second arc-shaped clamps on the upper and lower sides respectively. When the first and second arc-shaped clamps move, they compress the telescopic spring, using the elastic potential energy of the telescopic spring to clamp and fix the plug, thus preventing damage to the device connector caused by pulling the plug.

[0012] To achieve air circulation inside the casing, thereby ventilating and dissipating heat:

[0013] The further configuration includes: a heat dissipation vent is provided on the bottom surface of the outer casing, and a cooling fan and a dustproof baffle are fixedly installed on the inner side wall of the heat dissipation vent, with the dustproof baffle located below the cooling fan.

[0014] By adopting the above technical solution, a cooling fan is provided at the bottom of the casing. The cooling fan, together with the ventilation holes on the side wall of the casing, creates an air circulation inside the casing, thereby achieving the effect of ventilation and heat dissipation.

[0015] To achieve the effect of clamping and fixing the external plug:

[0016] The fixing component is further configured such that: the fixing assembly includes a fixing shell, and through holes are provided on both sides of the fixing shell;

[0017] The inner wall of the fixed shell is slidably connected with an arc-shaped clamping plate one and an arc-shaped clamping plate two. The bottom surface of the arc-shaped clamping plate one and the top surface of the arc-shaped clamping plate two are both fixedly connected with a telescopic spring.

[0018] By adopting the above technical solution, the external plug is inserted into the fixed shell through the through hole, and the plug is clamped and fixed by the arc-shaped clamps on the upper and lower sides.

[0019] To achieve the effect of the arc-shaped clamp sliding within the fixed shell:

[0020] The design is further configured such that: an L-shaped connecting plate is fixedly connected to the side wall of the arc-shaped clamping plate, and sliding holes are provided on both sides of the arc-shaped clamping plate.

[0021] By adopting the above technical solution, the arc-shaped clamping plate can slide within the fixed shell via the L-shaped connecting plate.

[0022] To achieve the effect of the arc-shaped clamping plate sliding within the fixed shell:

[0023] The design is further configured such that: an L-shaped connecting plate is fixedly connected to the side wall of the arc-shaped clamping plate two, and sliding holes are provided on both sides of the arc-shaped clamping plate two.

[0024] By adopting the above technical solution, the arc-shaped clamping plate 2 can slide and move within the fixed shell through the L-shaped connecting plate 2.

[0025] To achieve the effect of clamping and fixing the plug by inserting it into the retaining housing:

[0026] The configuration is further defined as follows: the first and second arc-shaped clamps are symmetrically abutted together, and the first and second arc-shaped clamps are joined together to form a circular hole, and the circular hole inside the first and second arc-shaped clamps is connected to the through hole.

[0027] By adopting the above technical solution, the external plug is inserted into the fixed shell through the through hole and passes between the arc-shaped clamping plate one and the arc-shaped clamping plate two, thereby being clamped and fixed.

[0028] To achieve the clamping and limiting effect using curved clamp plate one and curved clamp plate two:

[0029] The L-shaped connecting plate is further configured such that the outer side wall of the L-shaped connecting plate is slidably connected to the inner side wall of the sliding holes on both sides, and the outer side wall of the L-shaped connecting plate is slidably connected to the inner side wall of the sliding holes on both sides.

[0030] By adopting the above technical solution, the first arc-shaped clamping plate and the second arc-shaped clamping plate are slidably connected to each other through the first sliding hole and the second sliding hole, thereby achieving the effect of clamping and limiting.

[0031] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0039] Please see Figures 1 to 5 A housing for a smart substation secondary safety measure verification instrument includes an outer shell 1, with ventilation holes 2 on both sides of the outer shell 1.

[0040] A cooling fan 3 is installed inside the bottom surface of the outer casing 1, and a dustproof baffle 4 is provided on the bottom surface of the cooling fan 3;

[0041] Multiple sets of fixing components 5 are fixedly connected inside the side wall of the outer casing 1.

[0042] In this embodiment, as Figure 1 and Figure 2 As shown, a heat dissipation vent 11 is provided on the bottom surface of the outer casing 1. A cooling fan 3 and a dust baffle 4 are fixedly installed on the inner side wall of the heat dissipation vent 11. The dust baffle 4 is located below the cooling fan 3.

[0043] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the fixing component 5 includes a fixing shell 51, and through holes 511 are provided on both sides of the fixing shell 51.

[0044] The inner wall of the fixed shell 51 is slidably connected with an arc-shaped clamp 52 and an arc-shaped clamp 53. The bottom surface of the arc-shaped clamp 52 and the top surface of the arc-shaped clamp 53 are both fixedly connected with a telescopic spring 54.

[0045] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an L-shaped connecting plate 521 is fixedly connected to the side wall of the arc-shaped clamp 52, and sliding holes 522 are provided on both sides of the arc-shaped clamp 52.

[0046] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an L-shaped connecting plate 531 is fixedly connected to the side wall of the arc-shaped clamping plate 53, and sliding holes 532 are provided on both sides of the arc-shaped clamping plate 53.

[0047] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first arc-shaped clamp 52 and the second arc-shaped clamp 53 are symmetrically abutted together, and the first arc-shaped clamp 52 and the second arc-shaped clamp 53 are joined together to form a circular hole. The circular hole inside the first arc-shaped clamp 52 and the second arc-shaped clamp 53 is connected to the through hole 511.

[0048] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the outer side wall of the L-shaped connecting plate 521 is slidably connected to the inner side wall of the sliding hole 532 on both sides, and the outer side wall of the L-shaped connecting plate 531 is slidably connected to the inner side wall of the sliding hole 522 on both sides.

[0049] The computer software involved in the hardware carriers such as cooling fans in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0050] Therefore, the "cooling fan" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the calibration instrument housing of this application, in order to solve the corresponding technical problems to be solved by this application.

[0051] The housing of the intelligent substation secondary safety measure verification instrument operates as follows:

[0052] Firstly, a cooling fan 3 is installed on the bottom surface of the outer casing 1, and ventilation holes 2 are opened on both sides of the outer wall of the outer casing 1. The cooling fan 3 draws the air inside the outer casing 1 out and discharges it through the heat dissipation port 11. The cold air outside enters through the ventilation holes 2 on both sides, so that the air inside the outer casing 1 circulates and achieves the effect of ventilation and heat dissipation.

[0053] When an external plug needs to be connected to the device, the plug passes through the through hole 511 and between the arc-shaped clamp 1 52 and the arc-shaped clamp 2 53. During this process, the plug simultaneously squeezes the arc-shaped clamp 1 52 and the arc-shaped clamp 2 53. The arc-shaped clamp 1 52 and the arc-shaped clamp 2 53 simultaneously squeeze the upper and lower telescopic springs 54. The elastic potential energy of the telescopic springs 54 clamps and limits the plug, thereby preventing the plug from being pulled and causing damage to the device interface.

[0054] When it is necessary to unplug the plug, by pressing the L-shaped connecting plate 521 and the L-shaped connecting plate 531 at the same time, the arc-shaped clamping plate 52 and the arc-shaped clamping plate 53 move towards each other, thereby releasing the limit on the plug and allowing the plug to be pulled out from the through hole 511.

[0055] The cooling fan 3 can be of the known TL-C12C type, but is not limited to the above-mentioned model, all of which are known existing technologies;

[0056] Furthermore, the internal structure of the outer shell 1 has been fully disclosed in the utility model patent (CN223123209U: Intelligent Substation Handheld One-Button Safety Verification Instrument), which is a mature technology in this field, so it will not be repeated in the specification.

[0057] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0058] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0059] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only for the purpose of helping to understand the method and core ideas of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that due to the limitations of textual expression, there are objectively infinite specific structures.
