Description

Technical Field

[0001] This utility model relates to the field of communication relay device technology, specifically a communication relay device for confined space operations in thermal power plants. Background Technology

[0002] Communication relay devices for confined space operations in thermal power plants are technical equipment used to ensure smooth communication between workers in confined spaces and external command personnel. Confined spaces are usually characterized by complex structures, enclosed environments, and signal shielding, which can easily lead to communication interruptions or signal attenuation. Therefore, specialized relay devices are needed to enhance and forward communication signals.

[0003] Currently, most existing devices typically require maintenance personnel to hold them by hand or place them temporarily. In confined spaces with narrow and complex environments, these devices not only occupy both hands and affect other operations, but their placement is also unstable, posing a risk of falling. Furthermore, the disassembly and installation process is cumbersome and time-consuming, making it difficult to meet the needs of rapid operation and equipment adjustment. In view of this, we propose a communication relay device for confined space operations in thermal power plants. Utility Model Content

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-8This utility model proposes a communication relay device for confined space operations in thermal power plants, including a communication repeater 1, model number 712TR-R800, which is prior art and will not be described in detail in the specification. The communication repeater 1 has a power port 10 at its bottom and a snap-fit ​​slot 13 at the lower end of its housing, into which a battery 4 is inserted. This battery 4 insertion design reduces the size of the communication repeater 1 compared to traditional methods, making it easier to carry. A sliding groove 11 is provided on one outer wall of the communication repeater 1's housing, and a housing 14 is fixedly connected to the other outer wall of the housing. The sliding groove 11 allows for sliding... A sealing plate 12 is connected to the communication repeater 1. The design of the sealing plate 12 can prevent dust from entering the interface of the communication repeater 1 during maintenance. The housing 14 has a sliding groove 15. When installing the battery 4, it is easy to pull the limiting plate 16 so that the limiting plate 16 can be fully inserted into the housing 14. The limiting plate 16 is slidably connected to the inner wall of the housing 14. The design of the limiting plate 16 can limit the battery 4 and prevent the battery 4 from detaching from the communication repeater 1 during maintenance. The limiting plate 16 is elastically connected to the inner wall of the housing 14 by a spring. The communication repeater 1 has an antenna 2 at the top and a snap-fit ​​mechanism.

[0031] In the embodiments of this utility model, in order to facilitate operation in confined spaces, the snap-fit ​​mechanism specifically includes a fixing plate 31, which is fixedly connected to the outer shell of the communication repeater 1 by screws. The fixing plate 31 is slidably connected to a snap-fit ​​block 312, which has a slot 313. The fixing plate 31 has a through slot 311, and the inner wall of the base 32 has a snap-fit ​​slot 321 and a horizontal slot 322. Both sides of the base 32 are provided with straps 33, and both sets of straps 33 are provided with Velcro.

[0032] Furthermore, the base 32 is rotatably connected to a turntable 325, the turntable 325 has an arc-shaped groove 326, the horizontal groove 322 is slidably connected to a sliding rod 323, the sliding rod 323 is penetrated by a telescopic rod 324 and is slidably connected to the telescopic rod 324, the arc-shaped groove 326 is slidably connected to the sliding rod 323, and the outer wall of the telescopic rod 324 is elastically connected to the inner wall of the sliding rod 323 by a spring.

[0033] In this invention, during use, the strap 33 is first tied to the arm, then the fixing plate 31 is aligned with the base 32, and then the communication repeater 1 is pressed. At this time, the base 32 will squeeze the locking block 312, causing the locking block 312 to fully enter the fixing plate 31. During this process, the telescopic rod 324 will penetrate the through groove 311 and contact the outer wall of the locking block 312. At this time, the outer wall of the locking block 312 will apply a force to the telescopic rod 324, causing the telescopic rod 324 to move into the sliding rod 323. When the outer wall of the fixing plate 31 coincides with the outer wall of the base 32, the end of the locking block 312 will engage with the locking groove 323. When the two sides overlap, the locking block 312 will spring into the slot 321 under the elastic force of the spring, thereby fixing the communication repeater 1 to the arm. Through the design of the fixing plate 31, the base 32, and the strap 33, the communication repeater 1 can be bound to the arm, which effectively improves the convenience of the communication repeater 1, so that maintenance personnel can communicate with the outside world while working in a confined space. It should be noted that when the locking block 312 springs into the slot 321, the slot 313 opened on the locking block 312 will overlap with the telescopic rod 324. At this time, the telescopic rod 324 will spring into the slot 313 under the elastic force of the spring.

[0034] When disassembly is required, first rotate the turntable 325. During this process, the arc groove 326 will apply a force to the sliding rod 323, causing the sliding rod 323 to drive the telescopic rod 324 to slide on the transverse groove 322. During this process, the telescopic rod 324 will apply a force to the end of the slot 313, causing the locking block 312 and the telescopic rod 324 to move synchronously until the locking block 312 disengages from the slot 321, thereby allowing the communication repeater 1 to be disassembled.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
