[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] Embodiment 1:

[0028] See also Figure 1-4 A detachable guardrail protection device includes a guardrail body 10, the guardrail body 10 has at least two columns 11, and also includes a plug-in base 20, the plug-in base 20 includes a fixed column 22, and the fixed column 22 is provided with an annular groove 23, a connecting sleeve 12 is installed at the bottom of the column 11, the fixed column 22 is used to be inserted into the connecting sleeve 12, and a limiting device 40 is installed on the connecting sleeve 12, and when the limiting device 40 extends into the annular groove 23, the connecting sleeve 12 and the fixed column 22 are limited. When in use, the fixed column 22 of the plug-in base 20 is connected and fixed to the water operation equipment, and then the connecting sleeve 12 at the lower end of the guardrail body 10 is inserted from top to bottom into the fixed column 22, and then the limiting device 40 is extended into the annular groove 23, so that the guardrail body 10 is limited and fixed. When disassembly is required, the limiting device 40 is made to leave the annular groove 23, so that the guardrail body 10 can be extracted. Through the above-mentioned method, the guardrail body 10 can be conveniently disassembled and installed, thereby meeting the needs of different working environments.

[0029] Furthermore, the plug-in base 20 further includes a bottom plate 21, and the fixing column 22 is fixedly connected to the bottom plate 21. The bottom plate 21 provides a larger support area, and improves the installation stability of the fixing column 22. During installation, the bottom plate 21 is connected and fixed to the water operation equipment. The connection method can be bolt connection or welding.

[0030] In order to facilitate the insertion of the connecting sleeve 12 onto the fixing column 22, see Figure 4 The top of the fixing column 22 is provided with a chamfer 25. The chamfer 25 can be formed by a rounded corner or a right angle.

[0031] In this embodiment, the limiting device 40 is a bolt radially screwed on the connecting sleeve 12, and has a simple structure. When the guardrail body 10 needs to be fixed, the bolt is screwed so that the head of the bolt enters the annular groove 23, and the guardrail body 10 will not fall out; when the guardrail body 10 is disassembled, the bolt is loosened so that the head of the bolt exits the annular groove 23, and then the guardrail body 10 is lifted up, and the guardrail body 10 can be disassembled.

[0032] Embodiment 2:

[0033] The difference from the first embodiment is that, see Figure 3-7The limiting device 40 includes a wedge block 41, a connecting piece 42 and a spring 43. A mounting hole 13 is radially arranged on the connecting sleeve 12. The mounting hole 13 is a rectangular hole on the side close to the fixed column 22 and a round hole on the side away from the fixed column 22. The wedge block 41 and the spring 43 are installed in the rectangular hole. One end of the spring 43 abuts against the wedge block 41 and the other end abuts against the connecting sleeve 12. The connecting piece 42 penetrates into the rectangular hole from the round hole and is connected to the wedge block 41. A conical ring 24 is slidably installed on the annular groove 23; a retaining ring 30 is detachably installed on the fixed column 22.

[0034] For details, see Figure 3 The upper side of the wedge block 41 is a pointed portion near the end of the fixed column 22. When the wedge block 41 is extended or retracted, it will squeeze the spring 43. The conical ring 24 is a conical structure that is wide at the top and narrow at the bottom. A snap ring 30 is detachably mounted on the fixed column 22. When the snap ring 30 is removed, space is provided for the guardrail body 10 to move downward.

[0035] See also Figure 5 The snap ring 30 includes two half rings 31, and the two ends of the two half rings 31 are respectively provided with connecting holes 32, and the connecting holes 32 are installed with elastic members 33, and the two ends of the elastic members 33 are respectively connected with the latches 34 on the two half rings 31. The two half rings 31 are elastically connected, so that the snap ring 30 can be easily removed from the fixing column 22. The elastic member 33 can be a spring or a rubber, and the two ends of the spring or the rubber are hooked or tied on the latch 34.

[0036] In addition to the above structure, the clamp ring 30 may also adopt a clamp structure similar to that used for quick-release connectors.

[0037] Furthermore, handles 35 are fixedly connected to the two half rings 31 respectively, so as to facilitate applying force to the half rings 31 .

[0038] The working principle or action process of the utility model is as follows:

[0039] When installing the guardrail body 10, first insert the snap ring 30 onto the fixing column 22, then lift the guardrail body 10, and make the connecting sleeve 12 align with the fixing column 22 and insert it. At this time, the inclined surface of the wedge block 41 contacts the chamfer 25, the wedge block 41 retracts, and the connecting sleeve 12 is completely inserted into the fixing column 22. In this process, the wedge block 41 extends into the annular groove 23 under the action of the spring 43, and the guardrail body 10 will not fall out at this time. Figure 3 shown.

[0040] When the guardrail body 10 needs to be disassembled, the clamping ring 30 is first pulled open and clamped onto the connecting sleeve 12 or the column 11, and then the guardrail body 10 is moved downward. Figure 6Then the guardrail body 10 is lifted up again, and the tip of the wedge block 41 abuts against the outer wall of the conical ring 24 under the action of the spring, and the conical ring 24 moves up accordingly. When the conical ring 24 abuts against the upper end of the annular groove 23, Figure 7 The wedge block 41 contracts and transitions from the conical ring 24 to the fixing column 22, thereby removing the guardrail body 10.
