[0003] The prior art discloses a water conservancy project pipe protective cover with the authorization announcement number CN216643500U. The patent discloses a water conservancy project pipe protective cover, which is composed of a base and a pipe body. An inner sleeve is arranged on the upper side of the base and is sleeved on the outer periphery of the pipe body. An outer partition is arranged on the outer periphery of the outer sleeve. A plurality of vibration-damping springs arranged at equal intervals are fixed between the outer end surface of the inner sleeve and the inner end surface of the outer partition. A bottom plate is arranged on the lower side of the base, and a threaded rod threadedly connected to the base is rotatably installed in the bottom plate. When an external object or water flow impacts the protective cover, the outer partition can resist the collision, and the vibration-damping spring can absorb the impact force, thereby protecting the pipe body. In addition, the design of the bottom plate and the threaded rod can make the protective cover more stably fixed on the pipe to prevent it from moving or falling off.

A rack 124 is rotatably installed inside the protection shell 11. The rotating gear 121 is meshed with the rack 124. Four circumferentially uniformly distributed outer circular pressing blocks 125 are fixedly connected to the inner wall of the rack 124. Four circumferentially uniformly distributed inner circular pressing blocks 13 are slidably connected inside the protection shell 11. One end of the inner circular pressing block 13 is fixedly connected to a clamping block 132, and one side of the clamping block 132 is slidably connected to a protection block 133. A threaded rod 14 is rotatably installed inside, and a follower sector gear 141 is fixedly sleeved on the outer circumference of the threaded rod 14, and the active sector gear 122 is meshed with the follower sector gear 141. A lower pressure block 15 is threadedly sleeved on the outer circumference of the threaded rod 14, and four symmetrically arranged connecting screws 151 are fixedly connected to the bottom of the lower pressure block 15. Two symmetrically arranged limiting rods 142 are fixedly connected inside the protective shell 11. Through the arrangement of the pipeline protection mechanism 1, the knob 123 and other structures, when the pipeline needs protection, the pipeline body 10 is placed in the equipment, and then the knob 123 is rotated. The knob 123 rotates to extend the clamping block 132 and the connecting screw 151. The clamping block 132 has a protective block 133 to fix the pipeline body 10, and the connecting screw 151 is extended to complete the fixation of the equipment, thereby increasing the use efficiency of the equipment.

[0021] See also Figure 1 The connecting mechanism 2 includes a base 21 and a hexagonal bolt 22. The base 21 and the hexagonal bolt 22 are both arranged at the bottom of the protective shell 11. The bottoms of the threaded rod 14 and the two limit rods 142 are fixedly connected to the limit positioning blocks 143. Four circumferentially evenly distributed connecting blocks 101 are fixedly connected to the outer circumferential surface of the pipeline body 10. Through the arrangement of the connecting mechanism 2, the limit positioning blocks 143 and other structures, when the equipment is placed on the base 21, the three limit positioning blocks 143 are first placed in the preset holes of the base 21 to complete the positioning of the equipment. Then, after the connecting bolts fall, two hexagonal bolts 22 are installed on each connecting bolt to make the fixing of the equipment faster and more convenient.

[0022] See also Figure 1-3The interior of the pipe body 10 is provided with four circumferentially evenly distributed slide grooves, and four inner circle pressure blocks 13 are respectively slidably connected to the inside of the four slide grooves. Two symmetrically arranged rebound springs 131 are commonly connected between the inner circle pressure block 13 and the inner wall of the slide groove. A semicircular groove is provided inside the clamping block 132, and a protection block 133 is slidably connected inside the semicircular groove.

[0023] The specific implementation process of the utility model is as follows: when the pipeline body 10 needs to be protected, the pipeline body 10 is placed inside the protection shell 11, and then the knob 123 is turned. The knob 123 rotates to drive the rotating shaft 12 to rotate. The rotating shaft 12 rotates to drive the rotating gear 121 and the active fan-shaped gear 122 to rotate. The rotating gear 121 rotates to drive the rack 124 to rotate. The rack 124 rotates to make the outer circle pressing block 125 squeeze the inner circle pressing block 13, so that the inner circle pressing block 13 extends out. When the inner circle pressing block 13 extends out, it drives the clamping block 132 to extend out. The clamping block 132 has a protection spring 134 and a protection block 133 inside. In order to effectively protect the pipeline when in contact with the pipeline body 10, prevent the pipeline body 10 from being crushed when in contact with the pipeline body 10, and complete the installation of pipeline bodies 10 of different sizes, at the same time, the active sector gear 122 rotates to drive the follower sector gear 141 to rotate, and the follower sector gear 141 rotates to drive the threaded rod 14 to rotate, and the threaded rod 14 rotates to press the lower pressing block 15 downward. Due to the limit rod 142, the downward pressing direction of the lower pressing block 15 is always fixed. The downward pressing of the lower pressing block 15 presses down the four connecting bolts at the bottom of the lower pressing block 15, and the connecting bolts are extended while the pipeline body 10 is installed, thereby improving its use efficiency;

[0024] Furthermore, before installing the equipment, three limit positioning blocks 143 can be placed in the preset holes of the base 21 to complete the positioning of the equipment and the base 21. Then, after the connecting bolts pass through the base 21, two hexagonal bolts 22 are installed on each connecting bolt, so that the installation of the equipment is stable and the installation process is simple and convenient.
