[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] Please see Figures 1-6 This utility model provides a technical solution: a protective device for monitoring instruments in thermal power plants, comprising:

[0028] Example 1: As Figures 1-4 The present invention provides a technical solution: a protective device for a power plant testing instrument, comprising: a protective cover 1, on which an instrument body 2 is fixedly installed; heat dissipation holes 3, which are opened on the inside of the protective cover 1; a first protective component 4, which is disposed on the outside of the protective cover 1; and a second protective component 5, which is disposed on the upper end of the protective cover 1; wherein, the first protective component 4 is used to close the protective cover 1; and the second protective component 5 is used to block the upper end of the protective cover 1.

[0029] The first protective component 4 includes a concentric shaft 401, a protective cover 402, and an observation window 403. The protective cover 402 is rotatably connected to the outside of the protective cover 1 via the concentric shaft 401, and the observation window 403 is fixedly installed on the inside of the protective cover 402. The first protective component 4 also includes a connecting buckle 404, which is fixedly installed on the outside of the protective cover 402. The first protective component 4 also includes a locking plate 405, a fixing block 406, a first telescopic spring 407, and a locking rod 408. The locking plate 405 is fixedly installed on the outside of the protective cover 1, and the fixing block 406 is fixedly installed on the outside of the locking plate 405. The first telescopic spring 407 is fixedly connected to the outside of the fixing block 406, and the locking rod 408 is fixedly connected to the tail end of the first telescopic spring 407. The locking rod 408 passes through the inside of the fixing block 406, and the tail end of the locking rod 408 is engaged with the inside of the connecting buckle 404.

[0030] After the instrument body 2 is no longer in use, manually pull down the lever 408, then rotate the protective cover 402 via the concentric shaft 401 to make the protective cover 402 fit against the outside of the protective cover 1 until the buckle eye of the connecting buckle 404 aligns with the tail end of the lever 408. After fitting, release the lever 408, and the lever 408 will be reset by the elastic force of the first telescopic spring 407, so that the tail end of the lever 408 passes through the inside of the connecting buckle 404. The engagement of the tail end of the lever 408 with the connecting buckle 404 fixes the protective cover 402, sealing the protective cover 1 and preventing the instrument body 2 inside from being impacted. When the instrument body 2 needs to be used, pull down the lever 408 to separate the tail end of the lever 408 from the connecting buckle 404. After separation, rotate the protective cover 402 via the concentric shaft 401 to open the inside of the protective cover 1, at which point the instrument body 2 inside the protective cover 1 can be used.

[0031] Example 2: Figures 1-3 , Figures 5-6 The present invention provides a technical solution: a protective device for a thermal power plant testing instrument, which discloses that: the second protective component 5 includes a sliding groove 501, a second telescopic spring 502, and a sliding block 503. The sliding groove 501 is opened inside the protective cover 1, and the sliding block 503 is slidably connected to the inner side of the sliding groove 501. The second telescopic spring 502 is connected between the sliding block 503 and the inner wall of the sliding groove 501. The second protective component 5 also includes a support rod 504 and a rain shield 505. The support rod 504 is rotatably connected to the outer side of the sliding block 503, and the rain shield 505 is rotatably connected to the upper end of the support rod 504. The rain shield 505 and the protective cover 1 are distributed vertically and vertically, and the rain shield 505 has a conical structure when viewed from the front. There are two sets of support rods 504 symmetrically distributed about the midpoint of the rain shield 505.

[0032] This structure uses a rain shield 505 on the top of the protective cover 1 to isolate rainwater and prevent it from corroding the outer shell of the protective cover 1. When debris falls from the roof of the factory building, the rain shield 505 at the top of the protective cover 1 will rotate after being impacted, causing the support rod 504 to rotate. The rotation of the support rod 504 will push the sliding block 503 to slide along the inner side of the slide groove 501 and squeeze the second telescopic spring 502. The elastic force of the second telescopic spring 502 will buffer the impact force and prevent the impact force from being too large and causing a strong vibration, which could damage the instrument body 2 inside the protective cover 1.

[0033] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
