Description

Technical Field

[0001] This utility model relates to the technical field of underground fire prevention monitoring, and in particular to a subway electrical fire prevention monitoring device. Background Technology

[0002] Subway electrical equipment refers to the power distribution cabinets installed inside subway stations. To protect the internal fire safety of subway electrical equipment, fire monitoring devices are usually installed inside the equipment for real-time monitoring of internal short circuits or insulation faults to prevent electrical fires.

[0003] When existing fire monitoring devices are used to monitor subway electrical equipment, the ends of the wires are directly embedded into the installation end during installation. The rotating screw is directly pressed against the surface of the embedded wire for fixation. As a result, the small contact area during screw fixing and pressing leads to a small contact area of ​​the wire and loose installation. In some cases, excessive screw rotation force can deform or even break the wire end, causing inconvenience in installation, poor contact after installation, and difficulty in providing insulation protection for the end. This affects the convenience of installing wires at the installation end when using fire monitoring devices to monitor fire prevention of subway electrical equipment.

[0004] Therefore, in view of the above-mentioned defects, the designer of this utility model, through dedicated research and design, and by integrating years of experience and achievements in related industries, has researched and designed a subway electrical fire monitoring device to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this utility model is to provide a subway electrical fire monitoring device with a simple structure and convenient operation, so as to solve the problems of the prior art and avoid the defects of inconvenient installation, poor contact after installation and inconvenience in end insulation protection.

[0006] To achieve the above objectives, this utility model discloses a subway electrical fire prevention monitoring device, comprising a fire prevention monitoring device body, wherein the fire prevention monitoring device body is equipped with a fire prevention monitoring host, characterized in that:

[0007] Both sides of the fire monitoring host are provided with wiring terminals. Multiple mounting slots are formed equidistantly inside each wiring terminal. A conductive sheet is fixed to the bottom of each mounting slot by screws. The conductive sheet is electrically connected to the internal circuit board of the fire monitoring host through wires. Mounting holes are provided at the four corners of the fire monitoring host.

[0008] The fire monitoring device is equipped with an insulation protection installation mechanism, which includes an enlarged surface contact clamping component located at the top of the mounting groove. The end of the enlarged surface contact clamping component is equipped with a guide component. The end of the mounting groove is equipped with an insulation protection component on the surface of the wiring terminal, so that the insulation protection installation mechanism can easily increase the area of ​​the wire for reinforcement and provide insulation protection for the end after installation.

[0009] Wherein: the enlarged surface contact clamping assembly includes a screw threaded to the surface of the terminal, and the end of the screw thread extends into the interior of the mounting groove and is mounted with a mounting clamp via a rotating ring. The mounting clamp is correspondingly set to the upper surface of the conductive sheet so that when the screw thread is rotated, the mounting clamp moves downward to increase the area of ​​the wire for clamping and reinforcement, thereby making the installation less prone to squeezing damage.

[0010] Wherein: the guide assembly includes a guide rod fixed inside the mounting groove, and the guide rod passes through the tail end of the mounting clamp and is slidably connected to it.

[0011] Wherein: the mounting clamp is an arc structure so that it slides on the outer surface of the guide rod when the mounting clamp moves down, so as to stably move down and clamp for installation.

[0012] Wherein: the insulating protection component includes an internally threaded hole opened at the end of the mounting groove and located on the surface of the terminal. The internal thread of the internally threaded hole is connected to an insulating limiting externally threaded ring. The end of the insulating limiting externally threaded ring is elastically and tightly fitted with a flexible insulating sleeve. The insulating limiting externally threaded ring is connected to the inside of the mounting groove so that the insulating limiting externally threaded ring is limited and installed through the internally threaded hole, and after installation, the flexible insulating sleeve is tightly fitted and installed on the surface of the insulating limiting externally threaded ring.

[0013] The device also includes a deformation-resistant reinforcement mechanism, which includes a closed mounting component located at the corner of the fire monitoring host on one side of the mounting hole. The closed mounting component has a deformation-resistant reinforcement component inside, which is used to reinforce and protect the main body of the fire monitoring device by passing screws through the mounting hole.

[0014] Wherein: the closed mounting assembly includes an embedding groove located at the end and bottom of the fire monitoring host on one side of the mounting hole, and the embedding groove and the fire monitoring host are integrally injection molded.

[0015] Wherein: the anti-deformation reinforcement component includes a reinforcement base plate closed at the bottom of the embedded groove, and an integral reinforcement upper guard plate is provided at the end of the reinforcement base plate. The reinforcement upper guard plate is in contact with the upper surface of the fire monitoring host. Both the reinforcement upper guard plate and the reinforcement base plate have through holes inside, and the surfaces of the through holes and the mounting holes are correspondingly arranged to provide enhanced protection after the screws penetrate the interior of the through holes and the mounting holes.

[0016] As can be seen from the above, the subway electrical fire monitoring device of this utility model has the following effects:

[0017] 1. By designing an insulation protection installation mechanism, after the flexible insulation sleeve is installed through the insulation limiting external threaded ring, the wire passes through the flexible insulation sleeve and extends to the inside of the installation groove to contact the lower surface of the installation clamp. Rotating the screw in will move the installation clamp down and press the wire onto the surface of the conductive sheet, thereby increasing the contact area and reinforcing the installation during installation.

[0018] 2. When subjected to large installation forces, it is less likely to cause the ends of the conductors to be squeezed and shifted or to break due to compression. The increased contact area ensures stable installation. At the same time, the surfaces of the ends of two adjacent conductors at the connection terminals are insulated and protected by flexible insulating sleeves, ensuring safe use. This improves the tightness and insulation protection effect of the increased installation area of ​​the conductors in the fire monitoring device body when monitoring fire prevention of subway electrical equipment.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] See Figures 1 to 5 This invention demonstrates the subway electrical fire monitoring device.

[0028] The subway electrical fire prevention monitoring device includes a fire prevention monitoring device body 100. The fire prevention monitoring device body 100 is equipped with a fire prevention monitoring host 101. Both sides of the fire prevention monitoring host 101 are provided with wiring terminals 102. Multiple mounting slots 104 are formed equidistantly inside each wiring terminal 102. The bottom of each mounting slot 104 is fixed with a conductive sheet 105 by screws. The conductive sheet 105 is electrically connected to the internal circuit board of the fire prevention monitoring host 101 through wires. Mounting holes 103 are provided at the four corners of the fire prevention monitoring host 101.

[0029] The fire monitoring device body 100 is equipped with an insulation protection installation mechanism, which includes an enlarged surface contact clamping component located at the top of the mounting groove 104. The end of the enlarged surface contact clamping component is equipped with a guide component, and the end of the mounting groove 104 is equipped with an insulation protection component on the surface of the terminal 102. This allows the fire monitoring device body 100 to be used and installed by embedding the wire into the mounting groove 104 inside the terminal 102. The insulation protection installation mechanism facilitates the reinforcement of the wire by increasing its area, and provides insulation protection to the end after installation, ensuring safe use.

[0030] To facilitate the reinforcement and installation of the wire by increasing the area of ​​the clamping assembly, and to prevent deformation and breakage during installation, in this embodiment, preferably, the increased area clamping assembly includes a screw-in bolt 1021 threaded onto the surface of the terminal 102, and the end of the screw-in bolt 1021 extends into the interior of the mounting groove 104 and is mounted with a mounting clamp 1026 via a rotating ring. The mounting clamp 1026 is correspondingly arranged with the upper surface of the conductive sheet 105, so that rotating the screw-in bolt 1021 can drive the mounting clamp 1026 to move downward to increase the area of ​​the wire for clamping and reinforcement, effectively strengthening it and preventing damage from compression during installation.

[0031] In order to facilitate the stable downward movement and clamping of the mounting clamp 1026 by means of the guide assembly, in this embodiment, preferably, the guide assembly includes a guide rod 1025 fixed inside the mounting groove 104, and the guide rod 1025 passes through the tail end of the mounting clamp 1026 and is slidably connected to it. Preferably, the mounting clamp 1026 has an arc-shaped structure, which can guide and slide on the outer surface of the guide rod 1025 when the mounting clamp 1026 moves downward, so as to stably move downward and clamp for installation.

[0032] To facilitate insulation protection of the wires on the surface of terminal 102 using an insulation protection component, in this embodiment, preferably, the insulation protection component includes an internally threaded hole 1024 located at the end of the mounting groove 104 on the surface of terminal 102. An insulating limiting external threaded ring 1023 is threadedly connected inside the internally threaded hole 1024. A flexible insulating sleeve 1022 is elastically and tightly fitted at the end of the insulating limiting external threaded ring 1023. The insulating limiting external threaded ring 1023 is connected to the interior of the mounting groove 104. The insulating limiting external threaded ring 1023 can be limited and installed through the internally threaded hole 1024, and after installation, the flexible insulating sleeve 1022 is tightly fitted onto the surface of the insulating limiting external threaded ring 1023.

[0033] It is also equipped with an anti-deformation reinforcement mechanism, which includes a closed installation component located at the corner of the fire monitoring host 101 on one side of the mounting hole 103. The closed installation component is equipped with an anti-deformation reinforcement component inside. When the fire monitoring device body 100 is installed by screws passing through the mounting hole 103, the anti-deformation reinforcement mechanism can strengthen the protection of the edge of the mounting hole 103, making it less likely to cause deformation and breakage.

[0034] To facilitate the installation of the reinforcing base plate 1032 and the reinforcing upper guard plate 1033 through the closed installation assembly, and to facilitate the closure of excessively reinforced protection, in this embodiment, preferably, the closed installation assembly includes an embedding groove 1031 located at the end and bottom of the fire monitoring host 101 on one side of the mounting hole 103. The embedding groove 1031 and the fire monitoring host 101 are integrally injection molded. Preferably, the reinforcing base plate 1032 is closed on the lower surface of the embedding groove 1031, and the end of the reinforcing upper guard plate 1033 is closed at the end of the embedding groove 1031, facilitating closed installation and enhanced use.

[0035] Therefore, in order to facilitate the installation of the anti-deformation reinforcement component to protect against deformation when the screw penetrates the interior of the mounting hole 103, in this embodiment, preferably, the anti-deformation reinforcement component includes a reinforcing base plate 1032 closed at the bottom end of the embedded groove 1031. The end of the reinforcing base plate 1032 is integrally provided with a reinforcing upper guard plate 1033. The reinforcing upper guard plate 1033 contacts the upper surface of the fire monitoring host 101. Both the reinforcing upper guard plate 1033 and the reinforcing base plate 1032 have through holes 1034 formed inside, and the through holes 1034 are correspondingly arranged with the surface of the mounting hole 103. The reinforcing base plate 1032 can be closed at the bottom end of the embedded groove 1031, and the reinforcing upper guard plate 1033 contacts the upper surface of the fire monitoring host 101, so that the through holes 1034 are correspondingly arranged with the mounting hole 103. After the screw penetrates the interior of the through holes 1034 and the mounting hole 103, it is used for reinforcement protection and is not easily squeezed, broken or damaged when subjected to excessive force.

[0036] As can be seen from the above structure, the working principle and usage process of this utility model are as follows: When using this subway electrical fire monitoring device, the first step is installation. The ends of the reinforcing base plate 1032 and the reinforcing upper guard plate 1033 are closed inside the embedding groove 1031. After closing, the through holes 1034 and mounting holes 103 on the reinforcing base plate 1032 and the reinforcing upper guard plate 1033 correspond. Then, the main body 100 of the fire monitoring device is closed inside the subway electrical equipment installation location. Screws penetrate the through holes 1034 and mounting holes 103. The device is fixedly installed by rotating and embedding into the internal threaded groove of the external installation location. When the screw is rotated and fixed, it applies force to the surface of the reinforced upper guard plate 1033 and the reinforced base plate 1032 to strengthen them. This protects the corner installation location of the fire monitoring host 101. When the rotation installation is subjected to large forces, it is less likely to cause the fire monitoring host 101 and the installation hole 103 to be squeezed and damaged. This ensures a stable installation, extends the service life, and improves the deformation resistance and fixation of the installation hole 103 of the fire monitoring device body 100 during the installation of fire monitoring for subway electrical equipment.

[0037] Then, after the main body 100 of the fire monitoring device is fixedly installed, the insulating limiting external threaded ring 1023 is rotated and installed again inside the internal threaded hole 1024. After installation, the end of the insulating limiting external threaded ring 1023 deforms due to the flexibility of the flexible insulating sleeve 1022 and is tightly pressed against the end surface of the insulating limiting external threaded ring 1023. The installation wire is passed through the flexible insulating sleeve 1022 and the insulating limiting external threaded ring 1023 and extends to the inside of the mounting groove 104 to contact the lower surface of the mounting clamp 1026. The end of the screw-in bolt 1021 is rotated inside the mounting clamp 1026 and rotated in place through the connecting ring, so that the mounting clamp 1026... 1026 moves downward, and during the downward movement, the end slides stably on the outer surface of the guide rod 1025 until the mounting clamp 1026 drives the embedded wire to press tightly onto the surface of the conductive sheet 105. This facilitates increased contact area and reinforces the installation. When the installation force is large, it is less likely to cause the end of the wire to be squeezed and shifted or to break due to squeezing. Increasing the contact area stabilizes the installation, and at the same time, the ends of two adjacent wires on the surface of the terminal 102 are insulated and protected by flexible insulating sleeves 1022, ensuring safe use and improving the tightness and insulation protection effect of the increased area installation of the wires in the fire monitoring device body 100 during fire monitoring of subway electrical equipment.

Although embodiments have been described and illustrated in the accompanying drawings, this utility model does not limit the specific examples exemplified by the drawings and described in the embodiments as currently considered the best mode for implementing the teachings of this utility model.
