[0029] Embodiment 1:

[0030] A pipe protection device for a water conservancy project comprises a drain pipe 1 and a flange 2. The two drain pipes 1 are connected by the flange 2. A protection mechanism is arranged on the surface of the drain pipe 1 to protect the connection of the drain pipe 1.

[0031] The protection mechanism includes a first protection shell 3 and a second protection shell 4 sleeved on the surface of the drain pipe 1, the inner wall of the first protection shell 3 is fixedly connected with a sealing block 5, the inner wall of the second protection shell 4 is fixedly connected with a sealing shell 6 used in conjunction with the sealing block 5, the inner wall of the sealing shell 6 is fixedly connected with a sealing ring 7, and a fixing mechanism is provided on one side of the drain pipe 1, which can play a role in fixing the protection mechanism;

[0032] In this embodiment, by setting a protective mechanism, when the user needs to connect the drain pipe 1 during the implementation of a water conservancy project, the user can connect the drain pipe 1 by using the flange 2 and bolts, and then manually move the first protective shell 3 and the second protective shell 4 in the protective mechanism, so that the sealing block 5 can be driven by the first protective shell 3 to be inserted into the sealing shell 6 through the sealing plug, and the connection of the drain pipe 1 can be covered in the first protective shell 3 and the second protective shell 4, so as to protect the connection of the drain pipe 1. By setting the number of sealing rings 7 to be a plurality, the sealing performance in the sealing shell 6 is further increased, thereby improving the sealing performance of the connection between the first protective shell 3 and the second protective shell 4, and further improving the protection effect;

[0033] The problem that the bolts and flange 2 will inevitably rust or strip after long-term use and the influence of the external environment has been solved, and the existing drain pipe 1 does not have the function of protecting the connection of the drain pipe 1, which will cause damage to the connection of the drain pipe 1 during long-term use, seriously affecting its service life has been solved.

[0034] The number of sealing rings 7 is several and they are evenly distributed inside the sealing shell 6;

[0035] By setting a certain number of sealing rings 7 , the sealing performance inside the sealing shell 6 can be further increased, thereby improving the sealing performance of the connection between the first protective shell 3 and the second protective shell 4 , thereby further improving the protective effect.

[0036] Embodiment 2:

[0037] On the basis of the first embodiment, the protective mechanism in the first embodiment can play a role in protecting the connection of the drain pipe 1, but in this mechanism, the first protective shell 3 and the second protective shell 4 are fixed only by the way of clamping the sealing block 5 and the sealing shell 6, and the drain pipe 1 itself will vibrate when passing through the water flow, and when the water flow is large and the impact force is strong, the sealing block 5 will vibrate, and it may become loose during long-term use, thereby reducing the practicality of this device. The fixing mechanism in the present application includes a fixing block 8 fixedly connected to both sides of the second protective shell 4, a stabilizing block 9 is fixedly connected to one side of the fixing block 8, a connecting block 10 used in conjunction with the fixing block 8 is fixedly connected to the top of the first protective shell 3, two support frames 11 are arranged on the top of the stabilizing block 9, and two pull-out rods 12 are arranged on the top of the support frame 11, one end of the pull-out rod 12 passes through the bottom of the connecting block 10, and is fixedly connected with a plug-in block 13, and a spring 14 is fixedly connected to the top of the plug-in block 13, and the end of the spring 14 away from the plug-in block 13 is fixedly connected to the bottom of the support frame 11;

[0038] In this embodiment, by providing a fixing mechanism, when the user uses the protection mechanism, while the first protective shell 3 is moved, the fixing block 8 and the stabilizing block 9 in the fixing mechanism are driven to move closer to the position of the connecting block 10, and the pull-out plate 17 is manually pulled down, and the pull-out plate 17 is moved upward to drive the pull-out rod 12, the plug-in block 13 and the spring 14 to move upward. At this time, the spring 14 is in a stretched state. When the fixing block 8 drives the stabilizing block 9 to move into the square groove 15, the pull-out plate 17 is manually released, and the elastic force generated by the spring 14 can drive the pull-out rod 12 and the plug-in block 13 to be plugged into the plug-in hole 16, thereby playing a role in fixing the first protective shell 3 and the second protective shell 4;

[0039] When it is necessary to disassemble it, it is only necessary to perform the reverse operation as described above, which solves the problem that the first protective shell 3 and the second protective shell 4 are fixed only by the sealing block 5 and the sealing shell 6 in the mechanism, while the drain pipe 1 itself will vibrate when passing through the water flow, and when the water flow is large and the impact force is strong, the sealing block 5 will vibrate, which may cause loosening during long-term use.

[0040] A square groove 15 is provided on the top of the connecting block 10, and the square groove 15 is used in conjunction with the stabilizing block 9;

[0041] By providing the square groove 15, when the first protective shell 3 drives the second protective shell 4 to approach each other, the fixing block 8 and the stabilizing block 9 can be driven to be inserted into the square groove 15, thereby further improving the fixing effect.

[0042] The square slot 15 has two plug holes 16 formed inside, and the plug holes 16 are used in conjunction with the plug block 13;

[0043] By providing the insertion hole 16 , the elastic force generated by the spring 14 can drive the pull rod 12 and the insertion block 13 to be inserted into the insertion hole 16 , thereby playing a role in fixing the first protective shell 3 and the second protective shell 4 .

[0044] One end of the pull rod 12 is fixedly connected to a pull plate 17, and the pull plate 17 is made of silicone.

[0045] By setting the pull-out plate 17 and the material of the pull-out plate 17 to be silicone, the contact area between the palm of the user and the pull-out rod 12 can be increased, so that the user can pull the pull-out rod 12 better.

[0046] Working principle: When the user needs to connect the drain pipe 1 during the implementation of the water conservancy project, the user can connect the drain pipe 1 by using the flange 2 and bolts, and then manually move the first protective shell 3 and the second protective shell 4 in the protection mechanism, so that the sealing block 5 can be driven by the first protective shell 3 to be inserted into the sealing shell 6 through the sealing ring 7, so that the connection of the drain pipe 1 can be covered in the first protective shell 3 and the second protective shell 4, so as to protect the connection of the drain pipe 1. By setting the number of sealing rings 7 to be a certain number, the sealing performance in the sealing shell 6 is further increased, thereby improving the sealing performance of the connection between the first protective shell 3 and the second protective shell 4, and further improving the protection effect;

[0047] When the user uses the protective mechanism, the first protective shell 3 moves, which drives the fixed block 8 and the stabilizing block 9 in the fixing mechanism to approach the position of the connecting block 10. The pull-out plate 17 is manually pulled down, and the pull-out plate 17 moves upward, driving the pull-out rod 12, the plug-in block 13 and the spring 14 to move upward. At this time, the spring 14 is in a stretched state. When the fixed block 8 and the stabilizing block 9 move into the square groove 15, the pull-out plate 17 is manually released, and the elastic force generated by the spring 14 can drive the pull-out rod 12 and the plug-in block 13 to be plugged into the plug-in hole 16, thereby fixing the first protective shell 3 and the second protective shell 4.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
