DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-3 In this embodiment, a guardrail suitable for protecting irregular holes in water operations includes a base plate 1, and a limiting mechanism is provided on the upper surface of the base plate 1. The limiting mechanism includes a first sleeve 2 fixedly installed on the upper surface of the base plate 1, and a slot 3 is provided in the first sleeve 2. A first connecting frame 4 is slidably connected in the slot 3, and a connecting mechanism 5 is provided on the outer peripheral wall of the first connecting frame 4.

[0026] The connecting mechanism 5 includes a second sleeve 51 fixedly mounted on the left surface of the first connecting frame 4 , a connecting ring 52 rotatably mounted on the right surface of the first connecting frame 4 , and a clamping mechanism 6 fixedly mounted on the outer peripheral wall of the first connecting frame 4 .

[0027] It should be noted that the second sleeve 51 and the connecting ring 52 are located in the same plane, so that the two first connecting frames 4 can be inserted into the second sleeve 51 through the connecting ring 52 for fixation.

[0028] The clamping mechanism 6 includes a spring 61 fixedly mounted on the outer peripheral wall of the first connecting frame 4, a first limiting frame 62 fixedly mounted on the outer peripheral wall of the spring 61, a rotating groove 63 opened in the first limiting frame 62, and a limiting rod 64 rotatably mounted on the outer peripheral wall of the first connecting frame 4.

[0029] In this embodiment, a first fixing rod 7 is fixedly connected inside the first connecting frame 4, a second fixing rod 8 is fixedly connected between the first fixing rod 7 and the first connecting frame 4, and a warning sign 9 is hinged on the front surface of the second fixing rod 8. By hingedly connecting the warning sign 9, it is convenient to replace the warning sign 9.

[0030] In this embodiment, the second sleeve 51 is matched with the connecting ring 52 , so that the connecting ring can be inserted into the second sleeve 51 , thereby achieving a limiting effect, thereby limiting the position between the two first connecting frames 4 .

[0031] In this embodiment, there are two first limiting frames 62 , which are respectively located at the front and rear ends of the first connecting frame 4 . By providing two first limiting frames 62 , the limiting effect can be increased.

[0032] In this embodiment, the diameter of the first sleeve 2 is fifty millimeters, and the inner diameter of the second fixing rod 8 is twenty-five millimeters.

[0033] In this embodiment, the inner diameter of the first fixing rod 7 is thirty millimeters, and the number of the second fixing rods 8 is three. By increasing the number of the second fixing rods 8, the fixing effect of the warning sign 9 during installation can be increased.

[0034] It should be noted that the outer wall of the first connecting frame 4 is painted with red and white paint, so as to enhance the warning effect of the first connecting frame 4 .

[0035] It should be noted that, in order to increase the stability during installation, the base plate 1 is made of a 250 mm square steel plate.

[0036] Embodiment 2:

[0037] See also Figure 1-3 On the basis of the first embodiment, the rotation direction of the limit rod 63 is lateral rotation, and the limit rod 64 is a rectangular rod. By setting the rotation direction of the limit rod 63 to lateral, it is convenient to adjust the angle between the two first connecting frames 4, thereby facilitating the adjustment of the angle between the two first connecting frames 4.

[0038] The working principle of the above embodiment is:

[0039] When the user needs to install, the user first inserts the first connecting frame 4 into the first sleeve 2, and then the user inserts the connecting ring 52 into the second sleeve 51, and then the user pulls the first limit frame 62 until the limit rod 64 can enter the rotating groove 63, rotates the limit rod 64 and inserts the limit rod 64 into the two first limit frames 62, thereby completing the entire operation process.

[0040] The above beneficial effects are:

[0041] By setting the first limiting frame 62, the rotating groove 63 and the limiting rod 64, the limiting effect can be increased. By setting the connecting mechanism 5, a connecting effect can be achieved. By setting the first fixing rod 7 and the second fixing rod 8, the strength of the first connecting frame 4 can be increased, and the installation of the warning sign 9 can be facilitated.

[0042] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
