DETAILED DESCRIPTION

[0016] 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.

[0017] Example

[0018] See also Figure 1-3 The present embodiment provides a sand screening device that is easy to separate for water conservancy construction, including a sand screening frame 1, an inlet pipe 2 and an outlet pipe 3. The upper end of the sand screening frame 1 is fixedly connected to the inlet pipe 2, and the lower end of the sand screening frame 1 is fixedly connected to the outlet pipe 3.

[0019] A sand screening net 8 is installed in the sand screening frame 1, and then a mounting ring 81 is fixedly connected to the side of the sand screening net 8, and the mounting ring 81 and the sand screening frame 1 are slidably connected. In order to prevent the screened sand from hindering the transportation of water, the sand screening net 8 is set to a cone shape, and one side of the sand screening frame 1 is fixedly connected to a collecting frame 11, so that the screened sand can be collected conveniently and timely, and the sand can be separated.

[0020] Specifically, in order to avoid the phenomenon of side accumulation, the gear ring 4 is fixedly connected to the lower end of the water inlet pipe 2 through a bearing, and the lower end of the gear ring 4 is fixedly connected to the mounting rod 5 near the side, the lower end of the mounting rod 5 is fixedly connected to the mounting frame 6, and the lower end of the mounting frame 6 is slidably connected to the scraper 7. The mounting rod 5 can be driven to move by the gear ring 4, so that the scraper 7 at the lower end of the mounting frame 6 can move in a circular shape, scrape off the sand accumulated on the mounting ring 81, and push it to the side of the collection frame 11.

[0021] At the same time, a gear 9 is also meshed on one side of the gear ring 4, and the upper end of the gear 9 is fixedly connected to the output end of the servo motor 10. The servo motor 10 is fixedly connected to the sand screening frame 1 through the motor box, so that the entire structure can drive the gear 9 to rotate through the servo motor 10, thereby causing the gear 9 to drive the gear ring 4 to rotate and drive the lower end scraper 7 to move.

[0022] Specifically, springs 83 are fixedly connected to both sides of the lower end of the mounting ring 81 , the lower end of the spring 83 is fixedly connected to the sand screening frame 1 , a telescopic tube 82 is sleeved outside the spring 83 , and the upper end of the telescopic tube 82 is fixedly connected to the mounting ring 81 .

[0023] When water impacts the sand screening net 8, the impact force will push the sand screening net 8 down and squeeze the spring 83, causing the spring 83 to contract, which can play a certain role in protecting the sand screening net 8, and due to the impact effect of water, when the impact weakens, the spring 83 will also drive the sand screening net 8 to recover, causing the sand screening net 8 to shake in the up and down directions, thereby bouncing off the stuck sand and stones to avoid clogging the sand screening net 8, playing a certain combing role.

[0024] The scraper 7 is still in contact with the mounting ring 81 , the upper end of the scraper 7 is fixedly connected to the elastic sheet 61 , and the upper end of the elastic sheet 61 is fixedly connected to the mounting frame 6 .

[0025] After the sand screening net 8 is lowered, if the scraper 7 cannot be adjusted, it will not be able to scrape cleanly. Therefore, an elastic sheet 61 is installed on the scraper 7, so that the elastic sheet 61 can drive the scraper 7 to descend, so that the scraper 7 can normally contact with the mounting ring 81.

[0026] When the utility model is used, when the water in the water conservancy project is transported, the water starts to be transported through the water inlet pipe 2, the water will enter the sand screening frame 1, and pass through the conical sand screening net 8 to filter out the sand and gravel in the water, and be guided by the conical sand screening net 8 to move to the side, and at the same time, the servo motor 10 is started to drive the gear 9 of the servo motor 10 to rotate, the gear 9 drives the gear ring 4 to rotate, the gear ring 4 drives the lower end mounting rod 5 to move, the mounting rod 5 drives the mounting frame 6 to move, the mounting frame 6 drives the lower end scraper 7 to move in a circular trajectory on the surface of the mounting ring 81, and pushes the sand and gravel that fall on the mounting ring 81 to move, so that it moves to the position of the collection frame 11 on one side, and enters the collection frame 11 for collection.

[0027] Although the 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.
