[0003] Current water-utilizing grates have a fixed height after being installed in the water. Although they can effectively block impurities in the water, when the water level rises and becomes too high, the grates will be submerged, making them too short to block the impurities that have risen to the surface. This affects the grates' blocking effect and reduces their practicality. Therefore, a water-utilizing grates with better blocking performance are needed to solve the above problems.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] like Figures 1 to 4As shown, a hydraulic screen with good blocking effect includes a screen body 1. Several connecting slots 2 are evenly distributed on one side of the screen body 1. Connecting blocks 3 are engaged with the inner walls of each connecting slot 2. Connecting holes 4 are formed on the bottom sides of each connecting block 3. Several connecting bolts 5, matching the size of the connecting holes 4, are threaded onto one side of each screen body 1. Several guide holes 6 are formed on the top side of the screen body 1. Guide rods 7 are slidably connected to the inner walls of each guide hole 6. A float plate 8 is fixedly connected to the top of each guide rod 7. Several crossbars 9 are slidably connected to the outer surfaces of each guide rod 7. Flexible connecting ropes 10 are fixedly connected between the crossbars 9, between the uppermost crossbar 9 and the float plate 8, and between the lowermost crossbar 9 and the connecting blocks 3. When connecting the float plate 8 to the screen body 1, the guide rods 7 are first inserted into the guide holes 6, and then connected by a flexible connecting rope 10. The connecting block 3 can be rotated and smoothly inserted into the connecting slot 2. At this time, the connecting bolt 5 corresponds to the position of the connecting hole 4. Then, the connecting bolt 5 is rotated to connect with the connecting hole 4, thereby fixing the connecting block 3. The main body 1 of the grid is provided with a connecting structure 11. After the float 8 is installed, the guide rod 7 is retracted into the guide hole 6, and several crossbars 9 are stacked together. When the water level rises, the float 8 will move with the rise of the water level. As the float 8 moves, the guide rod 7 moves out from the inside of the guide hole 6, and at this time, the flexible connecting rope 10 at the top position drives a crossbar 9 to move upward. At this time, the impurities on the water surface are blocked by several guide rods 7, float 8 and crossbars 9. If the water level rises significantly, all the flexible connecting ropes 10 are in a stretched state, and several crossbars 9 are evenly distributed from top to bottom. The impurities on the water surface are blocked by several guide rods 7, float 8 and crossbars 9.

[0022] As an optional technical solution of this utility model, the connecting structure 11 includes a connecting shell 1101, a fixing spring 1102, a positioning block 1103, a movable block 1104, a fixing rod 1105, a positioning slot 1106, and a fixing hole 1107. A plurality of connecting shells 1101 and a plurality of fixing springs 1102 are fixedly connected to one side of the grille body 1. A positioning block 1103 is fixedly connected to one end of each of the connecting shells 1101. Vertical rods are fixedly connected to the top and bottom sides of each positioning block 1103, thereby enabling better blocking of impurities. A movable block 1104 is fixedly connected to one end of each of the fixing springs 1102. A fixed rod is fixedly connected to the side of each movable block 1104 away from the fixing spring 1102. The fixed insert rod 1105 is provided. Several positioning slots 1106 are provided on one side of the grille body 1. The inner wall of each positioning slot 1106 is provided with a fixed insertion hole 1107. After connecting two grille bodies 1, the fixed insert rod 1105 on one grille body 1 is first inserted into the positioning block 1103. At this time, the fixing spring 1102 is compressed. Then, the positioning block 1103 on one grille body 1 is inserted into the positioning slot 1106 on the other grille body 1. At this time, the fixed insert rod 1105 and the fixed insertion hole 1107 are aligned. Under the reaction force of the fixing spring 1102, the fixed insert rod 1105 is inserted into the fixed insertion hole 1107, thereby completing the operation of connecting the two grille bodies 1.

[0023] As an optional technical solution of this utility model, a fixed base 12 is fixedly connected to the bottom end of the grid body 1, and a number of fixing nails 13 are fixedly connected to the bottom side of the fixed base 12. The water conservancy grid can be fixed in a suitable position by the fixed base 12 and the fixing nails 13.

[0024] As an optional technical solution of this utility model, both the connecting block 3 and the connecting slot 2 are dovetail-shaped, and the sizes of the connecting block 3 and the connecting slot 2 are adapted to each other.

[0025] As an optional technical solution of this utility model, the positioning block 1103 and the positioning slot 1106 are both dovetail-shaped. The number of positioning blocks 1103 and the number of positioning slots 1106 are corresponding, the positions of positioning blocks 1103 and the positions of positioning slots 1106 are corresponding, and the sizes of positioning blocks 1103 and positioning slots 1106 are adapted to each other. The connection between the two grid bodies 1 is made more secure through the positioning blocks 1103 and the positioning slots 1106.

[0026] As an optional technical solution of this utility model, the fixed spring 1102 and the movable block 1104 are both located inside the connecting shell 1101. The movable block 1104 is slidably connected to the connecting shell 1101, so that the movable block 1104 can move smoothly along the direction of the connecting shell 1101. The fixed insertion rod 1105 passes through the connecting shell 1101 and is slidably connected to the connecting shell 1101. The fixed insertion rod 1105 passes through the positioning block 1103 and is slidably connected to the positioning block 1103. The size of the fixed insertion rod 1105 is adapted to the size of the fixed insertion hole 1107, so that the fixed insertion rod 1105 can be smoothly inserted into the interior of the fixed insertion hole 1107.

[0027] A hydraulic grating with good barrier effect works on the following principle:

[0028] When the water level rises, the float 8 will move with the rise in water level. As the float 8 moves, the guide rod 7 moves out from the inside of the guide hole 6, and at this time the flexible connecting rope 10 at the top position drives a crossbar 9 to move upward. If the water level rises significantly, an appropriate number of flexible connecting ropes 10 will be stretched, and impurities on the water surface will be blocked by several guide rods 7, float 8 and several crossbars 9.

[0029] In summary, this hydraulic grating with good blocking effect, through the coordinated arrangement of the grating body 1, connecting groove 2, connecting block 3, connecting hole 4, connecting bolt 5, guide hole 6, guide rod 7, float 8, crossbar 9, and flexible connecting rope 10, when the water level rises, the float 8 will drive the guide rod 7 to move upward, and at the same time, the flexible connecting rope 10 will drive the crossbar 9 to move. At this time, the flexible connecting rope 10, crossbar 9, and guide rod 7 form a blocking structure above the grating body 1, preventing impurities from falling from above the grating body 1. The arrangement of the connecting blocks 1101, 1102, 1103, 1104, 1105, 1106, and 1107 facilitates the connection of the two main bodies 1, improving the efficiency of connecting them. It also makes it easier to separate the two main bodies 1.
