Diversion equipment for water conservancy construction

Abstract

The present invention relates to the technical field of water conservancy construction, and specifically to a diversion device for water conservancy construction, comprising a sedimentation box, a water pumping pipe is fixedly arranged on the lower side of the sedimentation box, and a filter box is fixedly arranged on the upper side of the sedimentation box. In this diversion device for water conservancy construction, water from a discharge pipe flows into the irrigation pipes on both sides along the T-shaped passage of the column core. As the amount of water increases, the internal water pressure squeezes the airbag to inject air into the bottom of the vertical groove, and pushes the column core upward, so that the T-shaped passage is separated from the irrigation pipe and the discharge pipe, and is converted into a straight passage intervention, disconnecting the connection between the irrigation pipe and the discharge pipe. At this time, the water in the discharge pipe is directly discharged. When the stored water in the irrigation pipe flows out, the airbag loses pressure to move the column core downward, and water is stored again. Compared with the existing method of intercepting with a baffle, the column core can be automatically replenished according to the water storage situation in the irrigation pipe, and the irrigation pipe is closed when there is no water shortage, thereby effectively avoiding the evaporation of the stored water in the irrigation pipe and improving the stability of water storage.

[0009] A bracket is fixedly arranged at one end of the rotating shaft close to the irrigation pipe body, and an inner pipe for closing the irrigation hole is rotatably connected in the irrigation pipe. The inner pipe is fixedly connected to the bracket, and a connecting hole matching the irrigation hole is opened on the side surface of the inner pipe.

[0021] Preferably, a limiting strip is fixedly provided on the surface of the column core, and a limiting groove matching with the limiting strip is opened on the inner wall of the vertical groove.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In the present invention, water passing through the discharge pipe flows into the irrigation pipes on both sides along the T-shaped passage of the column core. As the amount of water increases, the internal water pressure squeezes the airbag to inject air into the bottom of the vertical groove, and pushes the column core upward, so that the T-shaped passage is separated from the irrigation pipe and the discharge pipe, and is converted into a straight passage intervention, disconnecting the connection between the irrigation pipe and the discharge pipe. At this time, the water in the discharge pipe is directly discharged. When the stored water in the irrigation pipe flows out, the airbag loses pressure and the column core moves downward, and water is stored again. Compared with the existing method of intercepting with a baffle, the above-mentioned column core can automatically replenish according to the water storage situation in the irrigation pipe, and close the irrigation pipe when there is no water shortage, thereby effectively preventing the stored water in the irrigation pipe from evaporating and improving the stability of water storage.

[0024] In the present invention, the water-absorbing pad is dampened and increased in weight by the water-drawing strip in contact with the ground, so that the weight of the auxiliary weight block is greater than the main weight block and falls on the bracket. At this time, the connecting hole and the irrigation hole are misaligned. After the soil dries, the water-absorbing pad loses weight. The main weight block presses the tilting rod to flip and rotates the rotating shaft and the inner tube. At this time, the connecting hole and the irrigation hole are aligned, and the water in the irrigation tube flows out for irrigation. After the soil is moistened, the inner tube can also be controlled to reset. Compared with the existing direct-connected water outlet structure, the above-mentioned water-drawing strip and the water-absorbing pad can control the weight ratio of the main weight block and the auxiliary weight block according to whether the soil is moist, and drive the inner tube to rotate to realize irrigation. On the one hand, reasonable irrigation can be carried out according to the soil conditions to avoid adverse effects caused by large amounts of water. On the other hand, the water stored in the tube can be accurately controlled to ensure the reasonable use of the stored water and avoid the inability to irrigate without water discharge.

[0025] In the present invention, the annular groove rotates synchronously along the top of the telescopic head, so that the inclined groove squeezes the telescopic head to move downward, so that it is inserted into the soil from the irrigation hole. At this time, the water in the pipe is poured into the soil. Compared with directly irrigating water on the soil surface, the telescopic head can guide water into the soil during irrigation, so that the irrigation water will not flood the surface, which can effectively prevent water flow from scouring the surface to cause soil and water loss or mud accumulation, which is beneficial to the subsequent irrigation effect.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical staff in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 11 The present invention provides a technical solution: a diversion device for water conservancy construction, comprising a sedimentation box 1, a pumping pipe 2 is fixedly arranged at the lower side of the sedimentation box 1, and a filter box 3 is fixedly arranged at the upper side of the sedimentation box 1, a discharge pipe 4 is arranged at the water outlet of the filter box 3, and the discharge pipe 4 and the filter box 3 are connected by a hose 5, the pumping pipe 2 draws the accumulated water in the construction area into the sedimentation box 1, and the larger sand and gravel therein are precipitated, and the overflowed sewage flows into the filter box for fine filtration, and the filtered water is discharged along the discharge pipe 4, and part of the water flows out along the irrigation pipe 6 for irrigation.

[0040] A plurality of irrigation pipes 6 are fixedly arranged on both sides of the discharge pipe 4, and irrigation holes 7 are opened on the bottom surface of the irrigation pipe 6. Part of the water in the discharge pipe 4 flows out along the irrigation pipe 6 for irrigation. Humidity controllers 8 matching the irrigation holes 7 are arranged on the irrigation pipe 6 and the discharge pipe 4.

[0041] The humidity controller 8 includes a sealing plate 81 fixedly installed along one end of the irrigation pipe 6 away from the discharge pipe 4, and a rotating shaft 82 is rotatably provided on the sealing plate 81, and a tilting rod 83 is fixedly provided at one end of the rotating shaft 82 close to the pipe mouth of the irrigation pipe 6, and one end of the tilting rod 83 is fixedly connected to a main weight block 84, and the other end of the tilting rod 83 is fixedly connected to a secondary weight block 85 matched with the main weight block 84, and a water-absorbing pad 86 is fixedly provided on the secondary weight block 85.

[0042] A bracket 87 supporting the water-absorbing pad 86 and the auxiliary weight block 85 is fixedly installed on the surface of the sealing plate 81, and a water diversion strip 88 is arranged on the auxiliary weight block 85. A through hole 89 cooperating with the water diversion strip 88 is opened on the lower side of the irrigation pipe 6, and the water diversion strip 88 extends from the through hole 89 to the outside. When the soil is dry, the water-absorbing pad 86 loses weight, and the main weight block 84 presses the tilting rod 83 to flip, and rotates the rotating shaft 82 and the inner tube 811. At this time, the connecting hole 812 is aligned with the irrigation hole 7, and the water in the irrigation pipe 6 flows out for irrigation. In order to prevent the tilting rod 83 from being placed vertically and unable to return to its original position after the main weight block 84 moves downward, a limit block can be set on the sealing plate 81. When the soil is wet, the water diversion strip 88 in contact with the ground makes the water-absorbing pad 86 damp and heavy, so that the weight of the auxiliary weight block 85 is greater than the main weight block 84 and falls on the bracket 87. At this time, the connecting hole 812 is misaligned with the irrigation hole 7.

[0043] A bracket 810 is fixedly provided at one end of the rotating shaft 82 near the pipe body of the irrigation pipe 6, and an inner pipe 811 that closes the irrigation hole 7 is rotatably connected inside the irrigation pipe 6. The inner pipe 811 is fixedly connected to the bracket 810, and a connecting hole 812 that matches the irrigation hole 7 is opened on the side surface of the inner pipe 811. Air holes can also be opened on the inner pipe 811 and the irrigation pipe 6 according to the symmetrical layout of the irrigation hole 7 and the connecting hole 812 to facilitate the internal water to flow out for irrigation.

[0044] An anti-loss component 813 is provided on the irrigation hole 7 and the inner tube 811 .

[0045] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the anti-loss component 813 includes a telescopic head 8131 slidably connected to the irrigation hole 7, and a spring 8132 is movably provided on the surface of the telescopic head 8131, the two ends of the spring 8132 are respectively connected to the telescopic head 8131 and the irrigation hole 7, and the spring 8132 pushes the telescopic head 8131 to slide into the irrigation pipe 6.

[0046] An annular groove 8133 matching with the telescopic head 8131 is provided on the surface of the inner tube 811, and an inclined groove 8134 of a semi-annular structure is provided in the annular groove 8133. The shallow end of the inclined groove 8134 corresponds to the connecting hole 812. When the inner tube 811 rotates to align the connecting hole 812 with the irrigation hole 7, the annular groove 8133 rotates synchronously along the top of the telescopic head 8131, so that the inclined groove 8134 squeezes the telescopic head 8131 to move downward, so that it is inserted into the soil from the irrigation hole 7.

[0047] The discharge pipe 4 is provided with a path switching component 8135 which cooperates with the irrigation pipe 6 .

[0048] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the path switching assembly 8135 includes a node seat 81351 arranged on the discharge pipe 4, and the position and number of the node seat 81351 correspond to the irrigation pipe 6.

[0049] The node seat 81351 is provided with a cross passage 81352 connecting the discharge pipe 4 and the irrigation pipe 6, and the node seat 81351 is provided with a vertical groove 81353 connected to the cross passage 81352, a column core 81354 is slidably connected in the vertical groove 81353, and a T-shaped passage 81355 is provided on the upper side of the column core 81354, and a straight passage 81356 with a straight-line structure is provided on the lower side of the column core 81354.

[0050] An air bag 81357 is provided in the irrigation pipe 6, and the air bag 81357 is connected with the interior of the vertical groove 81353 through a conduit 81358. When the water flowing into the discharge pipe 4 reaches the node seat 81351, it flows into the irrigation pipes 6 on both sides along the T-shaped passage 81355 of the column core 81354. As the amount of water increases, the internal water pressure squeezes the air bag 81357 to inject air into the bottom of the vertical groove 81353, and pushes the column core 81354 to move upward, so that the T-shaped passage 81355 is separated from the irrigation pipe 6 and the discharge pipe 4, and the straight passage 81356 is intervened to disconnect the irrigation pipe 6 and the discharge pipe 4. At this time, the water in the discharge pipe 4 is directly discharged.

[0051] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the filter box 3 is configured as a pull-out openable structure, and after opening the filter box 3, the sand and gravel filtered out from the inside can be cleaned.

[0052] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the irrigation pipe 6 is connected to the discharge pipe 4 via a flange structure, which allows the user to select irrigation pipes 6 of different lengths for assembly according to actual needs, thereby providing better flexibility of use.

[0053] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the inner wall of the irrigation hole 7 and the outer surface of the telescopic head 8131 are fixedly provided with mutually matching limiting rings, the two ends of the spring 8132 are installed on the limiting rings on both sides, and the limiting rings can limit the displacement of the telescopic head 8131 to ensure operational stability.

[0054] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown, the surface of the inner tube 811 is provided with balls that rotate to match the inner wall of the irrigation tube 6. When the inner tube 811 rotates, it contacts the irrigation tube 6 through the balls, which can reduce the friction between the two and reduce the wear of the components.

[0055] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11As shown, a limit strip is fixedly arranged on the surface of the column core 81354, and a limit groove matching with the limit strip is opened on the inner wall of the vertical groove 81353. The limit strip limits the column core 81354 along the limit groove so that it can only move up and down but not rotate, so as to avoid misalignment of the T-shaped passage 81355, the straight passage 81356 and the irrigation pipe 6 and the discharge pipe 4.

[0056] The use method and advantages of the present invention: When the diversion device for water conservancy construction is working and used, the working process is as follows:

[0057] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figures 5 to 11 As shown:

[0058] S1, the pumping pipe 2 pumps the accumulated water in the construction area into the sedimentation tank 1, and the larger sand and gravel therein are precipitated. The overflowing sewage flows into the filter box for fine filtration, and the filtered water is discharged along the discharge pipe 4, and part of the water flows out along the irrigation pipe 6 for irrigation.

[0059] S2. When the water flowing into the discharge pipe 4 reaches the node seat 81351, it flows into the irrigation pipes 6 on both sides along the T-shaped passage 81355 of the column core 81354. As the amount of water increases, the internal water pressure squeezes the airbag 81357 to inject air into the bottom of the vertical groove 81353, and pushes the column core 81354 to move upward, so that the T-shaped passage 81355 is separated from the irrigation pipe 6 and the discharge pipe 4, and the straight passage 81356 intervenes to disconnect the irrigation pipe 6 and the discharge pipe 4. At this time, the water in the discharge pipe 4 is directly discharged. When the stored water in the irrigation pipe 6 flows out, the airbag 81357 loses pressure and causes the column core 81354 to move downward, and water is stored again.

[0060] S3. When the external soil is moist, the water diversion strip 88 in contact with the ground makes the water-absorbing pad 86 damp and heavier, so that the weight of the auxiliary weight block 85 is greater than the main weight block 84 and falls on the bracket 87. At this time, the connecting hole 812 is misaligned with the irrigation hole 7. After the soil dries, the water-absorbing pad 86 loses weight, and the main weight block 84 presses the tilting rod 83 to flip, and rotates the rotating shaft 82 and the inner tube 811. At this time, the connecting hole 812 is aligned with the irrigation hole 7, and the water in the irrigation tube 6 flows out for irrigation. After the soil is moistened, the inner tube 811 can also be controlled to reset.

[0061] S4. When the inner tube 811 rotates to align the connecting hole 812 with the irrigation hole 7, the annular groove 8133 rotates synchronously along the top of the telescopic head 8131, so that the inclined groove 8134 squeezes the telescopic head 8131 to move downward, so that it is inserted into the soil from the irrigation hole 7. At this time, the water in the tube is poured into the soil.

[0062] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
