[0031] 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.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a water conservancy pipeline that is convenient for docking, including a flange A1, the outer wall of the flange A1 is detachably mounted with a flange B2 through a positioning component 3, the outside of the flange A1 and the flange B2 are both provided with water conservancy pipelines, and the pipelines are made of water conservancy environmentally friendly materials, the inner wall of the flange B2 is provided with a guide groove 4, the initial end of the guide groove 4 is matched with the size of the guide block 34, and the inner wall of the flange A1 is provided with an annular groove, so that the guide block 34 can rotate on the inner wall of the guide groove 4 when entering the inner wall of the flange A1, the surface of the flange B2 is provided with a through hole 5, and the inner wall of the flange A1 is provided with a support component 6.

[0033] Reference Figure 2-Figure 3 The positioning assembly 3 includes a positioning block 32, which is elastically connected to the inner wall of the top end of the flange A1 through a limit spring 31. One end of the limit spring 31 is fixedly connected to the inner wall of the top end of the flange A1, and the other end of the limit spring 31 is fixedly connected to the outer wall of the positioning block 32. The function of the limit spring 31 is to automatically reset the position of the positioning block 32 after being squeezed and moved. The positioning block 32 is slidably connected to the inner wall of the top end of the flange A1. A cavity is provided on the inner wall of the flange A1, so that when the flange A1 contacts the flange B2, it will squeeze the positioning block 32 to move on the inner wall of the flange A1.

[0034] Reference Figure 2-Figure 3 The outer wall of the positioning block 32 is plugged into the inner wall of the through hole 5, and the plugging between the two allows the guide block 34 to be positioned and fixed by plugging the positioning block 32 and the through hole 5 when the inner wall of the guide groove 4 is moved to the end, so that it is convenient for the staff to rotate the bolts to connect and fix the two sets of flanges A1 and flange B2. The connecting rod 33 passes through and is slidably connected to the inner wall of the surface of the flange A1. The positioning block 32 can be moved on the inner wall of the flange A1 through the connecting rod 33, so that the flange A1 and the flange B2 can be easily rotated and separated. The outer wall of the positioning block 32 is fixedly connected with the connecting rod 33, the outer wall of the flange A1 contacts the outer wall of the flange B2, and the surface of the flange A1 is fixedly connected with the guide block 34, which is slidably connected to the inner wall of the guide groove 4, and is rotated on the inner wall of the guide groove 4 by the guide block 34, and when it moves to the end, the bolt holes of the flange A1 and the flange B2 can be aligned.

[0035] Reference Figure 2-Figure 4The support assembly 6 includes a support block 63, which is elastically connected to the inner wall of the flange A1 through a return spring 62. One end of the return spring 62 is fixedly connected to the bottom end of the outer wall of the support block 63, and the other end of the return spring 62 is fixedly connected to the surface of the flange A1. The function of the return spring 62 is that after the sealing ring is inserted into the outside of the support block 63, the support block 63 will be pulled to move, and the return spring 62 will be elastically compressed to apply elastic support to the support block 63, so that the support block 63 can support the sealing ring. The support block 63 penetrates and is slidably connected to the surface of the guide column 61. By setting the guide column 61, the position of the support block 63 moving up and down is guided so that it will not be offset. The support block 63 is slidably connected to the inner wall of the flange A1 surface, and the surface of the flange B2 is provided with an annular groove that fits the support block 63, so that when the flange A1 and the flange B2 rotate, the support block 63 will not be affected. The inner wall of the flange A1 is fixedly connected with multiple groups of guide columns 61.

[0036] Working principle: When flange A1 and flange B2 need to be docked, first align the guide block 34 on flange A1 with the initial end of the guide groove 4 on the inner wall of flange B2. Since the initial end of the guide groove 4 matches the size of the guide block 34, the guide block 34 can be smoothly inserted into the guide groove 4. As flange A1 and flange B2 gradually approach and contact, flange B2 will squeeze the positioning block 32 on the inner wall of the top end of flange A1. After being squeezed, the positioning block 32 will slide in the inner wall of the top end of flange A1, compressing the limit spring 31. At the same time, the guide block 34 slides in the guide groove 4, guiding the relative movement of flange A1 and flange B2. When the guide block 34 slides to the end along the guide groove 4, the bolt holes of flange A1 and flange B2 are automatically aligned. Due to the annular groove design on the inner wall of flange A1, the guide block 34 can rotate on the inner wall of the guide groove 4. When the guide block 34 moves to the end of the guide groove 4, the positioning block 32 will be inserted into the through hole 5 on the surface of flange B2 under the reset action of the limit spring 31 to achieve preliminary positioning and fixation. This design makes it convenient for the staff to rotate the bolts later to firmly connect the two sets of flanges A1 and flange B2. Accurate positioning can ensure the sealing of the connection, reduce the risk of medium leakage, and thus reduce energy loss and environmental pollution.

[0037] Inside the pipeline, in order to ensure the sealing effect, the support assembly 6 on the inner wall of flange A1 plays a role. When the sealing ring is inserted outside the support block 63, the reset spring 62 will pull the support block 63 to move, so that the reset spring 62 is elastically compressed, thereby applying elastic support to the support block 63, allowing the support block 63 to prop up the sealing ring to achieve a good sealing effect. Under the guidance of the guide column 61, the support block 63 moves up and down accurately without offset, ensuring the stability and reliability of the seal, thereby avoiding the incompatibility of the sealing ring and the waste of water resources.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
