[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a dam pouring machine for water conservancy projects. Background Technique

[0002] Water conservancy projects are an important part of the country's infrastructure construction. As one of the important structures of water conservancy projects, the construction quality of dams is directly related to the benefits and safety of water conservancy projects. During the construction of dams, concrete pouring is a key link, which determines the firmness and durability of dams. Therefore, in order to meet the high standards and high-quality requirements of water conservancy projects for dam construction, advanced pouring technologies and equipment are needed. Among them, the dam pouring machine is an important piece of equipment;

[0003] At present, the water delivery pipe usually adopts a detachable design formed by a flange and a nozzle. For flange connection, the staff needs to hold the nozzle and the water delivery pipe by hand to align the threaded holes between the two, and then connect them through the flange. Holding the nozzle or the water delivery pipe for a long time is likely to cause pressure on the hand muscles of the staff, and then make their hands shake, resulting in the misalignment of the threaded holes in the nozzle and the water delivery pipe, and further causing the occurrence of installation errors. In view of the above defects, the present utility model is proposed. Content of the Utility Model

[0023] The following further elaborates the present utility model in combination with the accompanying drawings and embodiments regarding the above and other technical features and advantages of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Embodiment

[0024] As Figures 1-5 shown, the present utility model provides a dam irrigation machine for water conservancy projects, including a base 1. Two groups of water pumps 2 are provided on the top of the base 1. A water storage tank 3 is connected to the top of the water pumps 2 through pipes. Water delivery pipes 4 are provided on the front surfaces of the water pumps 2. Sprinkler heads 5 are connected to both sides of the water delivery pipes 4 through flanges. Positioning components 6 are provided between the sprinkler heads 5 and the water delivery pipes 4. A protection component 7 is provided outside the sprinkler heads 5;

[0025] The water delivery pipe 4 is connected to the sprinkler head 5 through the positioning component 6. The positioning component 6 is pre-fixed through the water delivery pipe 4. The protection component 7 is rotatably arranged on the sprinkler head 5 and is used to protect the sprinkler head 5;

[0026] The positioning component 6 includes a plurality of groups of positioning grooves 61 opened on the outer wall of the sprinkler head 5. Positioning posts 62 are provided on the surfaces of the water delivery pipes 4 in the positioning grooves 61. Fixed seats 63 are provided on the front surfaces of the water delivery pipes 4. First rotating rods 65 are rotatably arranged in the fixed seats 63. First torsion springs 64 are wound around the surfaces of the first rotating rods 65. Limiting plates 66 are provided on the outer end surfaces of the first rotating rods 65;

[0027] When the staff needs to connect the water delivery pipe 4 and the nozzle 5, first rotate the limit plate 66, so that the limit plate 66 drives the first rotating rod 65 to rotate in the fixed seat 63, and the first rotating rod 65 synchronously drives the first torsion spring 64 to twist. Then align the positioning column 62 with the positioning groove 61, so that the nozzle 5 drives the positioning groove 61 to slide on the positioning column 62 and align with the surface of the water delivery pipe 4. Then release the limit plate 66, so that the restoring force of the first torsion spring 64 drives the first rotating rod 65 to rotate back to its original position in the fixed seat 63, and the first rotating rod 65 drives the limit plate 66 to fit against the outer wall of the nozzle 5, so that the nozzle 5 is pre-fixed on the water delivery pipe 4, facilitating the staff to connect the water delivery pipe 4 and the nozzle 5.

[0028] The limit plate 66 is designed in a rectangular shape, and a soft pad is provided on the surface of the limit plate 66 facing the positioning groove 61. Through this design, when the limit plate 66 rotates on the surface of the nozzle 5, due to the design of the soft pad, it can effectively avoid the direct contact between the limit plate 66 and the surface of the nozzle 5, thus preventing the situation of surface damage to the limit plate 66 and the nozzle 5.

[0029] The first torsion spring 64 is wound around the middle position of the first rotating rod 65, and both ends of the first torsion spring 64 are welded to the inner wall of the fixed seat 63. Through this design, when the first torsion spring 64 forms a torsion driven by the rotation of the first rotating rod 65, the torsion is evenly transmitted to both ends of the first rotating rod 65, thereby improving the stability of the rotation of the first rotating rod 65 in the fixed seat 63 and preventing the situation that one side of the first rotating rod 65 is stressed too much and the first rotating rod 65 gets stuck in the fixed seat 63 and cannot rotate.

[0030] The protection component 7 includes fixing blocks 71 provided on the outer wall of the nozzle 5. Braking rods 72 are rotatably arranged in the fixing blocks 71. Anti-loosening washers are sleeved between the braking rods 72 and the fixing blocks 71. Protective covers 73 are provided on the bottom surfaces of the braking rods 72. Mounting blocks 74 are provided on the surface of the nozzle 5 facing the water delivery pipe 4. Second rotating rods 75 are rotatably arranged in the mounting blocks 74. Second torsion springs 76 are wound around both ends of the second rotating rods 75. Limit blocks 77 are provided on the bottom surfaces of the second rotating rods 75.

[0031] When the staff does not use the nozzle 5, first rotate the limit block 77 to make the limit block 77 drive the second rotating rod 75 to rotate within the mounting block 74, and continuously drive the second torsion spring 76 to twist. Then rotate the protective cover 73 to make the protective cover 73 drive the brake rod 72 to rotate within the fixed block 71, and make the brake rod 72 drive the protective cover 73 to block the nozzle 5. At this time, release the limit block 77, and use the restoring force of the second torsion spring 76 to drive the second rotating rod 75 to rotate back to its original position within the mounting block 74, and drive the limit block 77 through the second rotating rod 75 to make the limit block 77 squeeze the second torsion spring 76, so as to make the second rotating rod 75 protect the surface of the nozzle 5.

[0032] The protective cover 73 is designed to be transparent, and rubber layers are provided on the surface of the protective cover 73 facing the nozzle 5. Through this design, the staff can observe the situation on the surface of the nozzle 5 from the outside of the protective cover 73, so as to determine whether to clean the dust on the surface of the nozzle 5;

[0033] The surface of the limit block 77 facing the protective cover 73 is set to have a curvature matching the outer wall of the protective cover 73, and anti-slip lines are provided on the surface of the limit block 77 facing the protective cover 73. Through this design, the contact area between the limit block 77 and the protective cover 73 can be increased, thereby improving the stability of the limit of the limit block 77 on the protective cover 73.

[0034] The above is only the preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
