Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy and irrigation, and in particular relates to a water conservancy and irrigation channel. Background Art A water conservancy irrigation channel is a waterway that connects irrigation water sources and irrigated fields. When in use, the water drawn from the irrigation water source is transported and distributed to various parts of the irrigation area through the water conservancy irrigation channel, so that the irrigated fields can draw water from the water conservancy irrigation channel nearby for field irrigation.

[0002] When water is subsequently extracted for irrigation, it is usually necessary to place the extraction pipe directly inside the irrigation channel for extraction. However, since the irrigation channel is an open channel, there are certain inconveniences in use: 1. Leaves, mud and other debris on both sides of the irrigation channel will enter the irrigation channel under the influence of wind or rain, which may easily cause the extraction pipe to be blocked when the water in the irrigation channel is extracted, affecting the stability of the irrigation channel; 2. The mud and sand accumulated in the irrigation channel for a long time cannot be effectively cleaned, and will gradually accumulate and clog the bottom of the irrigation channel, limiting the supply of irrigation water and affecting the irrigation effect. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a water conservancy irrigation channel, wherein a spiral rod for removing silt in the channel is arranged in a collecting pool, and an interception frame for removing floating objects in the channel is arranged in the curved channel, which can fully separate silt and floating objects from the channel to avoid blockage of subsequent extraction pipes.

[0004] The technical solution adopted by the present invention is as follows: A water conservancy irrigation channel comprises a main channel, wherein a curved channel connected to the main channel is arranged at every other end of the main channel, a cushion block is laid in the curved channel, a sunken collection pool is arranged at a position corresponding to the curved channel in the main channel, and a cover plate is installed above the collection pool; the collection pool is divided into a sediment separation area and a debris storage area, a circular arc chamfer is arranged in the main channel and on both sides of the collection pool, and a through hole for achieving communication between the main channel and the sediment separation area is opened below the circular arc chamfer on one side of the sediment separation area; a spiral rod is installed at the bottom of the sediment separation area, one end of the spiral rod passes through the sediment separation area and is exposed in the debris storage area, and a first slave gear is installed on the exposed end; An interception frame is installed in the curved channel through a fixed plate, one end of the interception frame is located above the debris storage area in the collection tank, a transmission belt is provided above the interception frame, and a second slave gear for driving the transmission belt to rotate is installed on one side of the transmission belt.

[0005] Furthermore, one or two motors are provided above the cover plate. When one motor is provided, the motor drives the first slave gear and the second slave gear through a toothed belt at the same time; when two motors are provided, the two motors are separately connected to the first slave gear and the second slave gear through a toothed belt respectively; and an opening is provided above the cover plate for the toothed belt to pass through.

[0006] Furthermore, when using one motor, the number of teeth of the first slave gear is set to 5-10 times that of the main gear in the motor, and the number of teeth of the second slave gear is the same as the number of teeth of the main gear in the motor. This can slow down the rotation speed of the screw rod, so that the work of the screw rod and the transmission belt can be balanced, and avoid the screw rod rotating too fast when the motor is started, causing the water to enter the debris storage area after the sediment at the bottom of the sediment separation area is transported.

[0007] Furthermore, the sediment separation zone is located at one end of the collecting pool close to the water inlet direction of the main channel, and the sediment separation zone is in a contraction state from top to bottom, and the sediment can settle to the bottom of the sediment separation zone.

[0008] Furthermore, the pad is located at one end of the curved channel water inlet and is stepped with the inner bottom surface of the main channel. The pad is 10-20 cm higher than the inner bottom surface of the main channel as a whole, which can prevent the mud and sand under the water flow from entering the curved channel; the other end of the pad is inclined, so that the water flow can flow smoothly from the curved channel into the main channel.

[0009] Furthermore, the height of the through hole opened below the circular arc chamfer on one side of the sediment separation area is the same as the height of the cushion block, so that the sediment blocked by the cushion block can enter the sediment separation area.

[0010] Furthermore, a plurality of groups of pick teeth are installed on the surface of the transmission belt, each group of pick teeth is composed of a plurality of racks, and the length of each rack is different, so that the formed pick teeth are in a gradually shortened step shape.

[0011] Furthermore, a slot is provided at one end of the interception frame, through which the pick teeth can rotate.

[0012] Furthermore, an inclined platform is provided in the interception frame and below the transmission belt, and a plurality of interception teeth are provided on one side of the inclined platform. The lower ends of the interception teeth are in contact with the upper surface of the pad in the curved channel, so that the scraping teeth can fully remove the floating objects above the inclined platform.

[0013] Furthermore, the intercepting teeth are in the same plane as the upper surface of the ramp, and the overall inclination is set at an angle of 20-30 degrees to the surface of the pad below. This enables the floating objects intercepted by the intercepting teeth to move toward the top of the ramp under the impact of the water flow, and the movement of the transmission belt can pull the floating objects above the ramp into the debris storage area in the collection pool.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a spiral rod for removing sediment in the water channel in the collection pool. The sediment below the water flow of the irrigation channel is blocked by the pad and isolated in the main water channel. It will not enter the curved channel, but will enter the sediment separation area in the collection pool through the through hole below. The sediment can be subsequently precipitated in the sediment separation area. Through the rotation of the spiral rod, the precipitated sediment can be transferred to the debris storage area, so that the sediment in the main water channel can be continuously collected and processed. An interception frame for clearing floating objects in the canal is provided in the curved canal. Large floating objects will be blocked by the interception teeth under the interception frame and float above the inclined platform under the impact of the water flow. Finally, when the transmission belt rotates, the objects will be scraped into the debris storage area by the scraping teeth installed on the surface of the transmission belt. Through these structural arrangements, silt and floating objects can be fully separated from the canal to avoid blockage of subsequent extraction pipes.

[0015] The present invention arranges a curved channel and a collecting pool at intervals in the main water channel, which can disperse the sediment and floating objects in the main water channel, reduce the working pressure of a single collecting pool, and improve the treatment effect of sediment and floating objects in the main water channel.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only embodiments of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0019] As attached Figure 1-7 shown.

[0020] Embodiment 1: A water conservancy irrigation canal comprises a main canal 1, in which a curved canal 4 is arranged at intervals between the ends of the main canal 1, and the curved canal 4 is connected to the main canal 1. Figure 2 As shown, a sunken collecting pool 2 is provided at a position corresponding to the curved channel 4 in the main water channel 1, and the collecting pool 2 is divided into a sediment separation area 21 and a debris storage area 22, wherein the sediment separation area 21 is located at one end of the water inlet direction of the main water channel 1, and a circular chamfer is provided in the main water channel 1 and on both sides of the collecting pool 2, which can reduce the impact of the water flow on the main water channel 1, so that the water flow can flow smoothly among the main water channel 1, the curved channel 4, and the main water channel 1 in turn; and a through hole is opened below the circular chamfer on one side of the sediment separation area 21, which can realize the connection between the main water channel 1 and the sediment separation area 21.

[0021] As attached Figure 5 As shown, the sediment separation area 21 is in a contracted state from top to bottom, and a spiral rod 3 is installed at the bottom of the sediment separation area 21. One end of the spiral rod 3 passes through the sediment separation area 21 and is exposed in the debris storage area 22, and the exposed end is installed with a first slave gear 7; a cover plate 5 is installed above the collecting tank 2 by bolts, a motor 51 is provided above the cover plate 5, and a main gear is provided at one end of the motor 51. The motor 51 is connected to the first slave gear 7 through a toothed belt 52, and can drive the spiral rod 3 to rotate.

[0022] A cushion block 41 is laid in the curved channel 4. Figure 3 , 4 As shown, one end of the pad 41 located at the water inlet of the curved channel 4 is 10-20 cm higher than the inner bottom surface of the main channel 1, and is stepped with the inner bottom surface of the main channel 1, which can prevent the mud and sand under the water flow in the main channel 1 from entering the curved channel 4; the other end of the pad 41 is inclined, so that the water flow can flow smoothly from the curved channel 4 into the main channel 1.

[0023] An interception frame 6 is installed in the curved channel 4 through a fixing plate 65, and one end of the interception frame 6 is located above the debris storage area 22 in the collection tank 2. Figure 6As shown, a transmission belt 61 is provided above the intercepting frame 6, and the installation structure of the transmission belt 61 is the same as the structure used in the prior art assembly line, specifically: a transmission roller is installed at both ends above the intercepting frame 6 and located on the inner side of the transmission belt 61, and a second slave gear 8 is installed on one side of the transmission roller located above the collecting pool 2. The second slave gear 8 is connected to the main gear in the motor 51 through a toothed belt 52, and the rotation of the motor 51 can drive the transmission belt 61 to move.

[0024] On the basis of the above, a plurality of groups of teeth 64 are provided on the surface of the transmission belt 61, and the teeth 64 can be connected to the transmission belt 61 by bolts. Since the same motor 51 drives the screw rod 3 and the transmission belt 61 respectively, in order to avoid that when the motor 51 is started, the screw rod 3 rotates too fast, so that the sediment at the bottom of the sediment separation area 21 is transported and the water flow enters the debris storage area 22, the motor 51 adopts a low-speed motor, and the number of teeth of the first slave gear 7 can be set to 5 times, 6 times, 7 times, 8 times, 9 times or 10 times that of the main gear in the motor 51, so as to slow down the rotation speed of the screw rod 3; the number of teeth of the second slave gear 8 can be the same as the number of teeth of the main gear in the motor 51; thereby, the working balance of the screw rod 3 and the transmission belt 61 can be achieved.

[0025] An inclined platform 62 is provided in the interception frame 6 and below the transmission belt 61, and an interception tooth 63 is provided on one side of the inclined platform 62 and is arranged in the curved channel 4. The number of the interception teeth 63 is several, and the interval between adjacent interception teeth 63 is 5cm, 6cm, 7cm, 8cm, 9cm or 10cm, which can intercept larger floating objects in the water flow.

[0026] The lower end of the intercepting tooth 63 contacts the upper surface of the pad 41 in the curved channel 4, the intercepting tooth 63 and the upper surface of the inclined platform 62 are in the same plane, and the overall inclination angle is 20 degrees, 25 degrees or 30 degrees with the pad 41 below, so that the floating objects intercepted by the intercepting tooth 63 can move toward the top of the inclined platform 62 under the impact of the water flow, and the movement of the transmission belt 61 can pull the floating objects above the inclined platform 62 into the debris storage area 22 in the collection tank 2.

[0027] In order to enable the scraper teeth 64 to fully scrape away the floating objects above the inclined platform 62, the scraper teeth 64 are attached. Figure 6 , 7 As shown, it is composed of multiple racks, and the length of each rack is different. The formed pick teeth 64 are in a gradually shortened step shape, which can better contact with the upper surface of the inclined platform 62.

[0028] The use of this device is as follows: The irrigation canal is generally used intermittently. When the irrigation canal is used, the motor 51 is started intermittently, and the screw rod 3 and the transmission belt 61 are driven by the toothed belt 52 to move. The specific working time can be set to work for 1-5 minutes after every 3h, 5h, 8h or 10h.

[0029] During use, the silt in the canal is mostly below the water flow. When the water in the main canal 1 flows, when it passes through the curved canal 4, the silt below the water flow is blocked by the pad 41 and isolated in the main canal 1. It will not enter the curved canal 4, but will enter the silt separation area 21 in the collecting tank 2 through the through hole below. The subsequent silt can be precipitated in the silt separation area 21. Through the rotation of the spiral rod 3, the precipitated silt can be transferred to the debris storage area 22, so that the silt in the main canal 1 can be continuously collected and processed.

[0030] The water flow after filtering the silt is blocked by the pad 41 and enters the curved channel 4. Under the action of the intercepting teeth 63, larger floating objects will be blocked and float above the inclined platform 62 under the impact of the water flow. Finally, when the transmission belt 61 rotates, the scraping teeth 64 installed on the surface of the transmission belt 61 will scrape it into the debris storage area 22. Subsequently, the floating objects or silt stored in the debris storage area 22 can be cleaned regularly.

[0031] Embodiment 2: As attached Figure 8 As shown, the difference from Example 1 is that two motors 51 are provided above the cover plate 5, one end of each of the two motors 51 is provided with a main gear, and the two motors 51 are connected to the first slave gear 7 and the second slave gear 8 through a toothed belt 52 respectively.

[0032] By adding a motor in the cover plate 5, different motors can be used to drive the screw rod 3 and the transmission belt 61 to work respectively.

[0033] The common point with Example 1 is that the working cycle of the motor can be adjusted according to the amount of sand accumulation and floating objects in the current canal. In areas with more sand and floating objects, the working interval of the motor can be reduced so that it can fully clear the sand and floating objects to ensure normal use of subsequent irrigation.

[0034] Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
