Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and irrigation technology, specifically a dredging device for water conservancy and irrigation projects. Background Technology

[0002] In water conservancy irrigation, ditches are often used. The main function of ditches is to divert water to the location where irrigation is needed, in order to facilitate water flow.

[0003] To ensure smooth water flow, the sides and bottom of ditches are often made of cement. However, in some areas, river water is used for irrigation, which produces silt in the ditches. Over time, this silt settles on the bottom and sides of the ditches, hindering water flow. The current method of dredging involves workers manually removing the silt with shovels, which not only easily damages the cement surface of the ditches but is also time-consuming and labor-intensive. Utility Model Content

[0004] This utility model provides a dredging device for water conservancy and irrigation projects to overcome the deficiencies in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A dredging device for irrigation engineering includes a horizontal plate and positioning devices set on both sides of the bottom surface of the horizontal plate and fixed to the ground. A rotary motor is fixedly installed on the horizontal plate, and a roller is coaxially connected to the shaft of the rotary motor. A pull line is wound on the roller. A limit wheel is fixedly installed below the horizontal plate. The other end of the pull line passes under the limit wheel and is connected to a moving rod. A roller is installed below the moving rod. A vertical pipe with closed ends is vertically connected to the moving rod. Several nozzles facing the side wall and bottom of the ditch are placed on the vertical pipe. One end of the vertical pipe is connected to a spring tube, and the other end of the spring tube is connected to a water inlet pipe set on the horizontal plate. The other end of the water inlet pipe is connected to a water pump.

[0007] In use, the horizontal plate is first set above the ditch, with positioning devices on both sides of the plate fixed to the ground to secure it. Then, a rotary motor unwinds the roll while simultaneously pulling the moving rod a certain distance. After pulling the rod a certain distance, it is lowered. The water pump and rotary motor are then activated. The rotary motor drives the winding roller to rewind, causing the moving rod to move towards the winding roller. This movement of the moving rod moves the vertical pipe, while the water pump draws water into the inlet pipe, which then enters the spring tube. The spring tube then enters the vertical pipe and sprays water, allowing the vertical pipe to move while simultaneously spraying water. This spraying effectively cleans the sludge from the bottom and side walls of the ditch. A limiting wheel ensures that the pull line pulls the moving rod laterally, thus guaranteeing the lateral movement of the vertical pipe.

[0008] Preferably, the positioning device includes a support column fixedly mounted downwards, a base plate fixedly connected to the bottom surface of the support column, and a through hole for inserting a pin. The support column supports the horizontal plate, while the pin inserted into the through hole fixes the base plate to the ground, thereby fixing the support column and thus fixing the horizontal plate.

[0009] Preferably, the cross plate has a rectangular groove along its length, extending through both ends. A rectangular rod is installed within the groove, and a bolt is fixedly connected to the top surface of the rod. A strip groove is formed on the top surface of the cross plate, through which the bolt passes and is threaded with a nut. The rectangular rod can move along the rectangular groove, thereby changing the distance between two rectangular rods and thus the spacing between the supports, adapting to ditches of different widths. Rotating the nut secures the bolt to the cross plate, thereby fixing the rectangular rod to the cross plate.

[0010] Preferably, the two ends of the movable rod are vertically connected to a crossbar, and each end of the crossbar is equipped with a rotating wheel, which contacts the sidewall of the ditch. The rotating wheel's contact with the sidewall allows the ditch to move more linearly under the control of the limiting wheel.

[0011] Preferably, the device also includes an outer tube, with one end of the moving rod fitted inside the outer tube. The outer tube has a threaded hole, and a compression bolt for pressing the moving rod is threaded into the threaded hole. The vertical tube is vertically connected to the outer tube. The cooperation between the moving rod and the outer tube can adapt to trenches of different widths, while the compression bolt can ensure the fixation between the moving rod and the outer tube.

[0012] Preferably, the horizontal plate is fixedly connected downwards to one end of a telescopic rod with a locking function, and the other end of the telescopic rod is vertically connected to a connecting rod, with a limiting wheel mounted on the connecting rod. The telescopic rod can adjust the height of the limiting wheel, thereby ensuring that the limiting wheel can adapt to ditches of different depths.

[0013] The beneficial effects of this utility model are as follows: The use of this application can drive the rotating motor to rotate the roller to realize the winding of the line. The winding of the line drives the vertical pipe to move, and the water sprayed on the vertical pipe can clean the bottom and side walls of the ditch. At the same time, the movement of the vertical pipe drives automatic cleaning, ensuring that the ditch is cleaned more thoroughly. This not only avoids damage to the side walls and bottom of the ditch by the shovel, but also saves workers' time and physical strength. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of this utility model.

[0019] A dredging device for water conservancy and irrigation projects, such as Figure 1 As shown. It includes a horizontal plate 1 and positioning devices set on both sides of the bottom surface of the horizontal plate 1 and fixed to the ground. A rotary motor 2 is fixedly installed on the horizontal plate 1. A roller 3 is coaxially connected to the shaft of the rotary motor 2. A pull line 4 is wound on the roller 3. A limit wheel 15 is fixedly installed below the horizontal plate 1. The other end of the pull line 4 passes under the limit wheel 15 and is connected to a moving rod 5. A roller 7 is installed below the moving rod 5. A vertical pipe 6 with closed ends is vertically connected to the moving rod 5. Several nozzles facing the side wall and bottom of the ditch are placed on the vertical pipe 6. One end of the vertical pipe 6 is connected to a spring tube. The other end of the spring tube is connected to a water inlet pipe set on the horizontal plate 1. The other end of the water inlet pipe is connected to a water pump.

[0020] This application is mainly applicable to the straight sections of ditches. In use, the horizontal plate 1 is first placed above the ditch, with positioning devices on both sides of the horizontal plate 1 fixed to the ground to secure it. Then, the rotary motor 2 unwinds the roll while simultaneously pulling the moving rod 5 a certain distance. After pulling a certain distance, the moving rod 5 is lowered, and then the water pump and rotary motor 2 are started. The rotary motor 2 drives the winding roller 3 to wind up, thereby moving the moving rod 5 towards the winding roller 3. The movement of the moving rod 5 drives the movement of the vertical pipe 6, while the water pump draws water into the inlet pipe, which then enters the spring tube, which in turn enters the vertical pipe 6 and sprays water out. This allows the vertical pipe 6 to move while spraying water, effectively cleaning the sludge from the bottom and side walls of the ditch. The limiting wheel 15 ensures that the pull line 4 pulls the moving rod 5 laterally, thus ensuring the lateral movement of the vertical pipe 6.

[0021] The positioning device includes a support column fixedly mounted downwards, with a base plate 8 fixedly connected to the bottom surface of the support column. The base plate 8 has a through hole through which a pin can be inserted. The support column supports the horizontal plate 1, while the pin inserted into the through hole fixes the base plate 8 to the ground, thereby fixing the support column and thus fixing the horizontal plate 1.

[0022] The horizontal plate 1 has a rectangular groove along its length, extending through both ends. A rectangular rod 9 is installed within the groove, and a bolt is fixedly connected to the top surface of the rod 9. A strip groove 10 is formed on the top surface of the horizontal plate 1, through which the bolt passes and is threaded with a nut. The rectangular rod 9 can move along the rectangular groove, thereby changing the distance between two rectangular rods 9, and thus changing the spacing between the supports, adapting to trenches of different widths. Rotating the nut secures the bolt to the horizontal plate 1, thereby fixing the rectangular rod 9 to the horizontal plate 1.

[0023] The movable rod 5 is vertically connected to two crossbars 11 at both ends. Rotating wheels 12 are installed at both ends of the crossbars 11, and the rotating wheels 12 contact the sidewall of the ditch. The system also includes an outer tube 13, with one end of the movable rod 5 fitted inside the outer tube 13. The outer tube 13 has threaded holes, and a compression bolt for pressing the movable rod 5 is threaded into these holes. A vertical tube 6 is vertically connected to the outer tube 13. The cooperation between the movable rod 5 and the outer tube 13 can adapt to ditches of different widths, while the compression bolt ensures the fixation between the movable rod 5 and the outer tube 13. The rotating wheels 12 can contact the sidewall of the ditch, thus enabling better linear movement of the ditch under the control of the limiting wheel 15.

[0024] The horizontal plate 1 is fixedly connected downward to one end of a telescopic rod 14 with a locking function. The other end of the telescopic rod 14 is vertically connected to a connecting rod, and a limiting wheel 15 is mounted on the connecting rod. The telescopic rod 14 can adjust the height of the limiting wheel 15, thereby ensuring that the limiting wheel 15 can adapt to ditches of different depths.

[0025] The use of this application can drive the rotating motor 2 to rotate the roller 3 to achieve wire winding. The wire winding drives the vertical pipe 6 to move, and water sprayed on the vertical pipe 6 can clean the bottom and side walls of the ditch. At the same time, the movement of the vertical pipe 6 drives automatic cleaning, ensuring that the ditch is cleaned more thoroughly. This not only avoids damage to the side walls and bottom of the ditch by shovels, but also saves workers' time and physical strength.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
