[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a pipeline connection structure for municipal pipeline engineering, including a shell 1, a connecting shell 3 is fixedly connected to the right side of the inner wall of the shell 1, an inner cavity 4 is opened inside the shell 1, the outer wall of the connecting shell 3 is engaged with the inner cavity 4, a protective shell 5 is fixedly connected to the right end of the outer wall of the shell 1, a sealing ring 6 is fixedly connected to the middle part of the inner wall of the protective shell 5, the front and rear sides of the protective shell 5 are threaded with threaded knobs 7, the adjacent sides of the two threaded knobs 7 are respectively threadedly connected to the front and rear sides of the connecting shell 3, a plurality of locking components are equidistantly arranged on the right side of the inner wall of the protective shell 5, and an inspection mechanism 2 is arranged on the top wall of the shell 1; the locking components include a plurality of rotating columns 9, the two ends of the plurality of rotating columns 9 are respectively rotatably connected to the right side of the inner wall of the protective shell 5, the left sides of the plurality of rotating columns 9 are fixedly connected with locking plates 10, the outer wall of the shell 1 is opened with locking grooves 11 around the periphery, and the left sides of the plurality of locking plates 10 are respectively engaged with the corresponding locking grooves 11;

[0032] Specifically, the two pipe housings 1 are precisely aligned to ensure that their left and right ports are completely matched. Next, the connecting shell 3 on the left is tightly engaged with the inner cavity 4 to form a stable connection. On this basis, the two connecting columns 13 are precisely docked with the corresponding holes 14, thus completing the preliminary pipe connection. By turning the two threaded knobs 7 clockwise, the ends of the threaded knobs 7 are tightly connected to the two sides of the connecting shell 3. This step can not only enhance the stability of the right pipe housing 1 and the connecting shell 3, but also effectively prevent the connection from being directly exposed to the outside air, thereby reducing the possibility of rust at the pipe connection. In order to further improve the firmness of the connection, we can also flip multiple locking plates 10 so that the left ends of the multiple locking plates 10 are tightly engaged with the corresponding locking grooves 11. In this way, the connection between the protective shell 5 and the right pipe housing 1 will be more secure, further reducing the instability of the connection caused by rust at the pipe connection.

[0033] Reference Figure 1 and Figure 3 The right side of the inner wall of the protective shell 5 is provided with a plurality of grooves 12 at equal intervals, and the right sides of the plurality of locking plates 10 are respectively engaged with the corresponding grooves 12; the middle parts of the two threaded knobs 7 are fixedly connected with rubber pads 8;

[0034] Specifically, the plurality of grooves 12 are engaged with the right sides of the plurality of locking plates 10 , so that the restriction on the flipping of the locking plates 10 can be reduced, and the two rubber pads 8 can reduce the damage to the protective shell 5 caused by the threaded knob 7 .

[0035] Reference Figure 1 , Figure 2 and Figure 4The inspection mechanism 2 includes a rotary page 201, the left and right sides of the rotary page 201 are fixedly connected to the left side of the top wall of the shell 1, the front side of the rotary page 201 is fixedly connected to a flip cover 202, the front side of the flip cover 202 is fixedly connected to a bolt 203, the inner wall of the flip cover 202 is provided with a rotating groove 204, the middle part of the inner wall of the flip cover 202 is rotatably connected to a turntable 205, the bottom wall of the turntable 205 is fixedly connected to a force plate 206, and the top wall of the turntable 205 is fixedly connected to an indicator plate 207; the bottom wall of the flip cover 202 is fixedly connected to a sealing ring 208, and the outer wall of the sealing ring 208 is engaged with the top of the inner wall of the shell 1;

[0036] Specifically, when the fluid passes through the pipeline, it will exert a force on the force plate 206. This force will cause the force plate 206 to deflect to the right or left. This deflection process will trigger the turntable 205 and the indicator plate 207 to rotate in the rotating groove 204. By observing the degree of deflection of the indicator plate 207, we can judge the size of the water flow. When a blockage occurs somewhere in the pipeline system, the deflection angle of the indicator plate 207 of the next flow section will decrease. This phenomenon enables maintenance personnel to quickly find the location of the blockage. Once the blockage location is determined, the maintenance personnel can take appropriate measures to clear it. This not only improves the efficiency of maintenance work, but also greatly reduces the time required to find the blockage location, and the sealing ring 208 can improve the sealing of the flip cover 202.

[0037] Reference Figure 1 The upper and lower ends of the right side of the housing 1 are fixedly connected with connecting posts 13, and the upper and lower ends of the left side of the housing 1 are provided with holes 14, and the right ends of the two connecting posts 13 are respectively engaged with the corresponding holes 14;

[0038] Specifically, the right ends of the two connecting posts 13 are respectively engaged with the corresponding holes 14 , so that the connection effect of the housing 1 can be improved.

[0039] Working principle: When starting to install and connect, align the right end of the pipe housing 1 with the left end of another pipe housing 1, engage the left connecting housing 3 with the inner cavity 4, and engage the two connecting columns 13 with the corresponding holes 14 to complete the initial pipe connection. By turning the two threaded knobs 7 clockwise, the ends of the threaded knobs 7 are connected to the two sides of the connecting housing 3, thereby improving the fixing effect of the right pipe housing 1 and the connecting housing 3, and at the same time ensuring that the connection is not directly exposed to the outside air, reducing the possibility of rust. By flipping over multiple locking plates 10, the left ends of the multiple locking plates 10 are engaged with the corresponding locking grooves 11, thereby improving the locking effect of the protective shell 5 and the right pipe housing 1. The effect is further improved, and the connection effect of the pipeline shell 1 is further improved, and the connection instability caused by rust at the pipeline connection is greatly reduced. When the fluid passes through the pipeline, the fluid will exert force on the force-bearing plate 206, causing the force-bearing plate 206 to deflect to the right or left, thereby driving the turntable 205 and the indicator plate 207 to rotate in the rotating groove 204, so that the size of the water flow can be judged according to the deflection degree of the indicator plate 207. When a blockage occurs somewhere in the pipeline, the deflection angle of the indicator plate 207 of the next flow section is reduced, so that the maintenance personnel can quickly determine the blockage location and then complete the dredging work, so that the operator improves the maintenance efficiency and reduces the time to find the blockage location.
