[0002] Nowadays, irrigation canals and farm irrigation ditches have been largely transformed from earthen canals to concrete canals.

[0007] According to one embodiment of the present invention, the concrete channel water lifting device includes a driving mechanism, which is used to drive the two sides of the water baffle to move closer to or away from the inner walls of the two sides of the concrete channel, respectively.

[0009] According to one embodiment of the present invention, a third fixed seat is installed at the middle position near the top of the water baffle. The driving mechanism includes two cylinders, which are respectively fixed on opposite sides of the third fixed seat. Both cylinders are perpendicular to the third fixed seat. One cylinder is connected to the first side of the water baffle at one end away from the third fixed seat, and the other cylinder is connected to the second side of the water baffle at one end away from the third fixed seat.

[0010] According to one embodiment of the present invention, the water-blocking plate is telescopic, the telescopic direction of the water-blocking plate is perpendicular to the length direction of the top rod, and the top of the water-blocking plate is fixed to the lower surface of the top rod.

The side of the plate should be close to the inner wall of the ditch, and the top rod should rest on the soil on both sides of the concrete irrigation ditch. Then, the insertion pins from the pin mechanism should be inserted into the soil on both sides of the concrete irrigation ditch, sealing the ditch with the water-blocking plate. This gradually raises the water level in the concrete irrigation ditch until it exceeds the bottom of the irrigation inlet. Then, the concrete irrigation ditch lifting device can be removed.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1: This embodiment provides a concrete channel water-lifting device, including a top rod 2, a water-blocking plate 1, and a pin mechanism; the water-blocking plate 1 is installed on the top rod 2, and there are two pin mechanisms, which are respectively installed on both ends of the top rod 2; the pin mechanism includes a soil-inserting pin 4, which is used to insert into the soil on both sides of the concrete channel, and the water-blocking plate 1 is used to seal the concrete channel to raise the water level of the concrete channel.

[0023] In this embodiment, when the water flow in the concrete ditch is insufficient for irrigation, farmers can place the water-blocking plate 1 from the concrete ditch water-lifting device into the ditch, ensuring that the bottom of the water-blocking plate 1 is inserted into the soil on the bottom wall of the ditch. The side of the water-blocking plate 1 should be close to the inner wall of the ditch, and the top rod 2 should rest on the soil on both sides of the concrete ditch. Then, the insertion pin 4 from the pin mechanism should be inserted into the soil on both sides of the concrete ditch, sealing the concrete ditch with the water-blocking plate 1. This gradually raises the water level in the concrete ditch until it exceeds the bottom of the irrigation inlet. Then, the concrete ditch water-lifting device can be removed. Since the water-blocking plate 1 no longer obstructs the water flow from the concrete ditch, the water in the ditch flows into the irrigation inlet and into the farmland.

[0024] This eliminates the need for manual labor to block irrigation ditches with shovels or sacks to raise the water level for irrigation, reducing the farmers' workload and saving time and effort.

[0025] It should be noted that in this embodiment, the water-blocking plate 1 is in the shape of a water-blocking plate, and its length and width are fixed. The length and width of the water-blocking plate 1 need to be customized in advance according to the depth and width of the concrete water channel to ensure that when the water-blocking plate 1 is placed in the water channel, the water-blocking plate 1 can just block the concrete water channel. Although there may be gaps between the side of the water-blocking plate 1 and the inner wall of the water channel, the water flow rate at the gap is much smaller than the water flow rate in the water channel. Therefore, the water-blocking plate 1 can play a significant role in blocking water.

[0026] Preferably, the pin mechanism includes an L-shaped connecting rod 3. Holes are provided on both sides of the top of the top rod 2 for the bottom end of the connecting rod 3 to pass through. The bottom end of the connecting rod 3 passes through the holes in the top rod 2. An anti-detachment plate 301 is installed at the bottom end of the connecting rod 3. The top end of the insertion pin 4 is connected to the top end of the connecting rod 3, and the insertion pin 4 is perpendicular to the top rod 2. It should be noted that the length of the top rod 2 is greater than the width of the concrete channel. When the water-blocking plate 1 is placed into the channel, both sides of the top rod 2 fall into the soil on both sides of the channel. At this time, a tool can be used to press the connecting rod 3 downwards, causing the connecting rod 3 to pull the insertion pin 4 into the soil on both sides of the concrete channel.

[0027] Example 2: This second embodiment provides a concrete water channel water lifting device, such as... Figure 1 and Figure 2 As shown, the difference between the concrete channel water-lifting device in Embodiment 2 and Embodiment 1 is that the water-blocking plate 1 in this embodiment is telescopic, and a driving mechanism for driving the extension and retraction of the water-blocking plate 1 is added. The driving mechanism can drive both sides of the water-blocking plate 1 to move closer to or away from the inner walls of the concrete channel. The purpose of this is to seal the gap between the side of the water-blocking plate 1 and the inner wall of the concrete channel, making it easier to adapt to channels with small width changes.

[0028] Specifically, such as Figure 1 As shown, the water-blocking plate 1 includes multiple water-blocking plates connected in sequence, and the multiple water-blocking plates are distributed in a wave-like pattern. The water-blocking plate 1 is arranged laterally, that is, the extension and retraction direction of the water-blocking plate 1 is the same as the length direction of the top rod 2, so that the water-blocking plate 1 can extend and retract along the width direction of the water channel.

[0029] Furthermore, multiple sliding seats are installed on the top of the water baffle 1, and a slide rail is installed on the lower surface of the top rod 2 along its length. The sliding seats are slidably installed on the slide rail, and the sliding seats are upside down on the slide rail and can slide along the slide rail.

[0030] As a preferred embodiment, such as Figure 1 and Figure 2As shown, the drive mechanism includes a rotating rod 5, a driving bevel gear 502, a bidirectional threaded rod 6, a limiting rod 12, and two moving blocks 8. The rotating rod 5 is rotatably mounted in the middle position of the top rod 2 and is perpendicular to the top rod 2. The top of the rotating rod 5 is higher than the top rod 2, and its bottom extends to a position close to the middle of the baffle plate 1. The driving bevel gear 502 is fixedly mounted on the bottom end of the rotating rod 5.

[0031] Furthermore, two first fixed seats 101 are installed in the middle of the baffle plate 1. The two first fixed seats 101 are symmetrically arranged about the driving bevel gear 502 and are located below the driving bevel gear 502. The bidirectional threaded rod 6 is rotatably connected to the two first fixed seats 101, and the threads at both ends of the bidirectional threaded rod 6 are opposite in direction. Two moving blocks 8 are screwed to both ends of the bidirectional threaded rod 6 respectively. The two moving blocks 8 are located on the outside of the two first fixed seats 101 respectively. A fixing plate 102 is installed in the middle of the baffle plate 1. The fixing plate 102 is located below the first fixed seats 101. A limiting rod 12 is fixedly installed on the fixing plate 102. The limiting rod 12 is parallel to the bidirectional threaded rod 6. The bottom of each of the two moving blocks 8 is provided with a circular hole for the limiting rod 12 to pass through, so that the two moving blocks 8 are simultaneously slidably connected to the limiting rod 12.

[0032] A driven bevel gear 7 is fixedly installed near the middle of the bidirectional threaded rod 6. The driven bevel gear 7 is located between the two first fixed seats 101, and the driving bevel gear 502 meshes with the driven bevel gear 7. A crossbar 801 is installed on the side of each moving block 8 away from the driven bevel gear 7. The crossbar 801 is perpendicular to the moving block 8. Second fixed seats 103 are fixedly installed on both sides of the water baffle 1, and the two crossbars 801 are connected to the two second fixed seats 103 respectively.

[0033] After the water-blocking plate 1 is placed into the concrete channel, rotating the rotating rod 5 drives the driving bevel gear 502 to rotate. Since the driving bevel gear 502 and the driven bevel gear 7 mesh, they drive the bidirectional threaded rod 6 to rotate. Because the threads on both sides of the bidirectional threaded rod 6 are in opposite directions, they drive the two moving blocks 8 to move outwards simultaneously. The crossbars 801 on the two moving blocks 8 push the two sides of the water-blocking plate 1 to stretch outwards simultaneously until the two sides of the water-blocking plate 1 are tightly against the inner wall of the channel. In this way, the water-blocking plate 1 can greatly reduce the gap between its side and the inner wall of the concrete channel, so as to adapt to channels with small width variations.

[0034] It should be noted that although the water-blocking plate 1 can extend and retract, its extension and retraction amount is relatively small due to material limitations. Therefore, the width of the water-blocking plate 1 should be determined according to the width of the concrete channel, and at least ensure that the width of the water-blocking plate 1 in its fully extended state is very close to the width of the concrete channel.

[0035] Preferably, a handle 501 is installed on the top of the rotating rod 5.

[0036] As an alternative embodiment, such as Figure 3 As shown, the drive mechanism includes two cylinders 9, a third fixing seat 104 is fixedly installed on the top of the baffle plate 1 near the middle, and a plate is fixedly installed on each side of the baffle plate 1. Figure 3 The two ends of the cylinder 9 on the left side are fixed to the left side of the baffle plate 1 and the left side of the third fixing seat 104, respectively. The two ends of the cylinder 9 on the right side are fixed to the right side of the third fixing seat 104 and the right side of the baffle plate 1, respectively.

[0037] By controlling the simultaneous extension of the two cylinders 9, the two sides of the water baffle 1 can be driven to expand outwards simultaneously until the two sides of the water baffle 1 are tightly attached to the inner wall of the water channel.

[0038] It should be noted that the cylinder 9 is installed at a height close to the top rod 2 to prevent the cylinder 9 from being submerged in the water channel.

[0039] Example 3: like Figure 4 As shown, this embodiment three provides a concrete water channel lifting device. The difference between this embodiment three and embodiment one is that the water baffle 1 is telescopic and a driving mechanism for driving the extension and retraction of the water baffle 1 is added.

[0040] Specifically, such as Figure 4 As shown, the water baffle 1 is vertically arranged, that is, the extension and retraction direction of the water baffle 1 is perpendicular to the length direction of the top rod 2, and the top of the water baffle 1 is fixed to the lower surface of the top rod 2 by bolts.

[0041] Preferably, in this embodiment, the drive mechanism includes a threaded rod 10 and two telescopic rods 11. A bottom rod 105 is installed near the bottom of the baffle plate 1. The threaded rod 10 is screwed to the top rod 2. The top of the threaded rod 10 is higher than the top rod 2. A handle 501 is installed on the top of the threaded rod 10. The top of the telescopic rod 11 is connected to the top rod 2, and its bottom is connected to the bottom rod 105.

[0042] When the water-blocking plate 1 is inserted into the ditch and the soil-inserting pin 4 is inserted into the soil on both sides of the ditch, the threaded rod 10 is rotated, causing it to move downwards and push the bottom rod 105 downwards until the bottom of the water-blocking plate 1 acts on the inner bottom wall of the ditch. At this time, the telescopic rod 11 is in a stretched state. This can seal the gap between the bottom of the water-blocking plate 1 and the inner wall of the concrete ditch.

[0043] It should be noted that the width of the water-retaining plate 1 needs to be manufactured according to the actual width of the concrete channel to ensure that the side of the water-retaining plate 1 is close to the inner wall of the channel. Since the length of the water-retaining plate 1 is adjustable, it can adapt to channels with small depth variations.

[0044] In the description of this utility model, it should be noted that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components.
