Referring to fig. 6, the mounting frame 1a has an inverted L shape with a first vertical mounting position 1a1 and a second horizontal mounting position 1a2. The first installation position 1a1 is fixedly connected to the inner side surface of the cabinet door 3a, and a first through groove 3a1 for the second installation position 1a2 to penetrate is formed in the upper position of the cabinet door 3 a.

Referring to fig. 2, the mounting portion 1b is slidably connected to the first mounting position 1a1 up and down, specifically, a set of first linear guide rails 1a3 are fixedly connected to the first mounting position 1a1, and the mounting portion 1b is fixedly connected to a first mounting slider of the set of first linear guide rails 1a 3.

Referring to fig. 3, the mounting portion 1b is further provided with a temperature probe 1b1, a humidity probe 1b2, and a smoke probe 1b3. That is, the space in the control cabinet 3 is divided into a plurality of areas from top to bottom, and the mounting portion 1b intermittently moves so that the temperature probe 1b1, the humidity probe 1b2, and the smoke probe 1b3 cyclically measure these areas. And after the monitoring module 1 is mounted on the cabinet door 3a, a drag chain can be arranged between the mounting part 1b and the cabinet door 3a for the temperature measuring head 1b1, the humidity measuring head 1b2 and the smoke measuring head 1b3 to run.

The temperature probe 1b1, the humidity probe 1b2 and the smoke probe 1b3 are also connected to the terminal 2, and the measured data are displayed on the terminal 2.

Referring to fig. 2 and fig. 4, a rotating shaft 1c is rotatably connected to a first installation position 1a1 around a vertical axis, specifically, an upper bearing seat 1a4 and a lower bearing seat 1a4 may be fixedly connected to the first installation position 1a1, and two shaft ends of the rotating shaft 1c are respectively connected to inner rings of bearings in the two bearing seats 1a4 in a stepped manner.

The outer wall of the rotating shaft 1c is provided with a first spiral guide portion 1c1, and the pitches of the spiral lines are equal, and specifically, the first guide portion 1c1 may be a spiral guide groove.

The mounting portion 1b is fitted to the first guide portion 1c1, and is coupled to the first guide portion 1c1 as a guide groove, and the mounting portion 1b is provided with a first protruding portion that enters the guide groove. Thus, the rotation of the rotation shaft 1c drives the mounting portion 1b to slide. Specifically, the uppermost pause position of the mounting portion 1b corresponds to the upper end of the first guide portion 1c1, and each time the mounting portion 1b intermittently moves into the next pause position, the rotation shaft 1c rotates by 180 degrees. That is, the pitch of each intermittent movement of the mounting portion 1b is the pitch of the spiral line.

Referring to fig. 3 and 5, the rack and pinion mechanism 1d includes: a first gear 1d1, a rack 1d2, and a stepping motor 1d3. The first gear 1d1 is fixedly connected to the top end of the rotating shaft 1 c. The rack 1d2 is horizontally and slidably connected to the second installation position 1a2 along the first direction, specifically, an installation plate 1a5 is fixedly connected in the second installation position 1a2, a group of second linear guide rails 1a6 are fixedly connected on the surface, close to the first installation position 1a1, of the installation plate 1a5, and the rack 1d2 is fixedly connected to second installation sliding blocks of the group of second linear guide rails 1a 6. The stepping motor 1d3 drives the rack 1d2 to slide, and specifically, the rack 1d2 includes: a first tooth segment 1d2a in a lower position and a second tooth segment 1d2b in an upper position; the first tooth segment 1d2a is meshed with a first gear 1d1 on the rotating shaft 1 c; a second through groove 1a5a for the second tooth to pass through and slide is arranged at the upper position of the mounting plate 1a 5; the stepper motor 1d3 is fixedly connected to the surface of the mounting plate 1a5 away from the first mounting position 1a1, and the output shaft is fixedly connected with a second gear 1d3a meshed with the second tooth segment 1d2 b.

The parameters of the first gear 1d1 and the second gear 1d3a may be the same, so that each time the stepper motor 1d3 rotates 180 degrees, the mounting portion 1b completes one movement accordingly.

The camera 1e is rotatably connected to the second mounting position 1a2 around an axis parallel to the second direction, specifically, the camera 1e may be provided with a mounting seat 1e1, that is, the camera 1e is rotatably connected to the mounting seat 1e1, and the mounting seat 1e1 is fixedly connected to the second mounting position 1a2. The camera 1e is also connected to the terminal 2, and displays the photographed image on the terminal 2.

The linkage piece 1f is arranged between the camera 1e and the rack 1d2, and drives the camera 1e to swing up and down by the back and forth sliding of the rack 1d 2. The mounting part 1b moves downwards, and the camera 1e correspondingly swings downwards; the mounting portion 1b moves upward, and the camera 1e swings upward correspondingly. When the rack 1d2 is suspended, the mounting portion 1b is at one of the suspended positions, and the imaging is also at one of the suspended positions, and when both are at the suspended positions, the camera 1e, the temperature probe 1b1, the humidity probe 1b2, and the smoke probe 1b3 correspond to the same area. When abnormal data occurs in the temperature probe 1b1, the humidity probe 1b2, and the smoke probe 1b3, the photographed picture of the corresponding area can be intuitively seen from the terminal 2.

It can be seen that the size of the pitch for each movement is the same for the mounting portion 1 b; for the camera 1e, the angle of each rotation is different in magnitude, specifically, the angle of each rotation gradually decreases from the uppermost pause position to the lowermost pause position.

Referring to fig. 3, 7 and 8, optionally, a second guiding portion 1d2c for the linkage member 1f to cooperate is provided on the rack 1d2, and the specific second guiding portion 1d2c may be a guiding groove formed by connecting multiple guiding segments with different slopes.

The camera 1e is fixedly provided with a swing arm 1e2, the other end of the swing arm 1e2 horizontally slides in a linkage piece 1f along a second direction perpendicular to the first direction, specifically, the linkage piece 1f can be concave, the inner walls of two sides of the notch are provided with sliding grooves 1f2, the swing arm 1e2 is fixedly connected with a cylindrical rod, and two ends of the cylindrical rod enter into the two sliding grooves 1f2 respectively. In this way, the rack 1d2 slides, and drives the linkage piece 1f to slide up and down through the second guide part 1d2c, and then drives the camera 1e to rotate through the swing arm 1e 2. The joints between two adjacent guide sections at both ends of the second guide portion 1d2c correspond to several pause positions of the camera head 1 e.

Referring to fig. 7, further, the linkage member 1f is slidably connected to a mounting base 1e1 of the camera 1 e. In this way, the camera 1e and the link 1f can be detached together from the mount 1a, leaving the connection of the swing arm 1e2 and the link 1 f. Compared with the linkage piece 1f which is directly connected with the mounting frame 1a in a vertical sliding way, the assembly is more convenient.

Referring to fig. 1 and 9, optionally, each group of monitoring modules 1 further includes: and an outer screen 1g. The outer screen 1g is disposed on a side of the second mounting position 1a2 away from the first mounting position 1a1, and displays at least one of the following: data of the temperature probe 1b1, data of the humidity probe 1b2, data of the smoke probe 1b3, and a screen of the camera 1 e.
