[0001] The utility model relates to the technical field of monitoring and early warning, and in particular to a monitoring and early warning device based on confined space operations. Background Art
[0002] An explosion-proof gas monitoring system for confined space operations disclosed on a Chinese patent website (publication number: CN219320251U) solves the technical problem that when operating in confined spaces, the traditional explosion-proof gas monitoring system often cannot transmit the signal to the external supervisor for early warning due to the closed nature of the confined space, which poses a great safety hazard. As a result, accidents in confined space operations often occur. However, the following problems still exist:

Operating the monitoring equipment by hand may easily cause accidents such as the staff falling, which in turn may easily cause the staff to fall and damage the monitoring equipment. Therefore, it is not convenient to hold the monitoring equipment in hand all the time. At the same time, due to the diverse usage environments, the monitoring equipment is at risk of being squeezed, collided and damaged no matter where it is hung on the staff's body, making it inconvenient to use.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-Figure 3 A monitoring and early warning device based on confined space operations includes a monitoring device 1 with monitoring and early warning functions. A protective mechanism is installed on the outer surface of the monitoring device 1. The protective mechanism includes a protective sleeve 2. The inner wall of the protective sleeve 2 is provided with a thread. The inner wall of the protective sleeve 2 is threadedly connected with a threaded ring 21. The outer surface of one end of the threaded ring 21 is fixedly connected with a mounting plate 22. The mounting plate 22 is in an arc shape. The mounting plate 22 and the threaded ring 21 are both located in the protective sleeve 2. The inner wall surface of the mounting plate 22 is fixedly connected with a mounting box 23. The inner wall surface of the mounting box 23 is snap-fitted with the outer surface of the monitoring device 1.
[0024] In order to facilitate the carrying of the monitoring equipment 1, a fixing ring 24 is rotatably connected to the inner wall of the opening at one end of the protective sleeve 2 through a bearing, and a limiting rod 25 is fixedly connected to the side wall surface of one end of the fixing ring 24. The surface of the limiting rod 25 is slidably inserted into the side wall surface of the threaded ring 21, and the limiting rod 25 is used to limit the rotation of the threaded ring 21, so that the threaded ring 21 can be driven by the rotation of the protective sleeve 2. An arm guard strap 26 is fixedly connected to the inner wall surface of the fixing ring 24. The arm guard strap 26 is made of an elastic band. Only the upper and lower ends of the outer surface of the arm guard strap 26 are fixed to the inner wall of the fixing ring 24, so that the arm guard strap 26 can be extended and contracted during use.
[0025] In order to facilitate the wearing of the arm guard strap 26, a support ring 27 is fixedly connected to the outer wall surface of the arm guard strap 26, and the support ring 27 and the fixing ring 24 are respectively located at the two ends of the arm guard strap 26. The support ring 27 and the fixing ring 24 cooperate to stretch the arm guard strap 26, thereby facilitating the extension of the arm guard strap 26. The side wall surface of the support ring 27 is fixedly connected to the end surface of the limiting rod 25, and a groove 28 is provided on the upper end surface of the support ring 27. One end of the installation box 23 is located inside the groove 28. The groove 28 is provided on the upper end surface of the support ring 27, so that the installation box 23 can extend outward through the groove 28.
[0026] By installing a protective mechanism on the outer surface of the monitoring device 1, the protective sleeve 2 and the installation box 23 in the protective mechanism are used to wrap and protect the monitoring device 1, and the entire protective mechanism is installed on the forearm of the user through the arm guard strap 26, so that it is convenient to carry the monitoring device 1 and also convenient to protect the monitoring device 1 and the forearm of the human body through the protective mechanism, thereby facilitating use.
[0027] The outer surface of the support ring 27 is rotatably connected with a ball 3, and the surface of the ball 3 is slidably connected to the inner wall surface of the protective sleeve 2. The ball 3 is used to movably support the protective sleeve 2, thereby facilitating avoiding obstruction to the rotation of the protective sleeve 2.
[0028] Working principle:
[0029] When in use, the protective mechanism is sleeved on the forearm of the user through the arm sleeve 26, and the protective sleeve 2 is rotated. The threaded ring 21 is close to the surface of the fixed ring 24 under the joint action of the protective sleeve 2 and the limit rod 25, and the threaded ring 21 drives the monitoring device 1 to be retracted into the protective sleeve 2 through the mounting plate 22 and the mounting box 23;
[0030] When the monitoring device 1 needs to be used, the protective sleeve 2 is rotated anyway, and the threaded ring 21 is moved close to the surface of the support ring 27 under the joint action of the protective sleeve 2 and the limiting rod 25. The mounting plate 22 and the mounting box 23 drive the monitoring device 1 to extend outward through the groove 28, and then the monitoring device 1 is used.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
