Description

Technical Field

[0001] This utility model belongs to the technical field of dredging devices, and in particular relates to a dredging device for environmental engineering and environmental protection. Background Technology

[0002] In environmental engineering and environmental protection, ditches are core infrastructure for drainage, irrigation and sewage discharge. After long-term use, they are prone to accumulating silt, fallen leaves, domestic waste and other foreign objects. If they are not dredged in time, it will lead to a decline in the drainage capacity of the ditches, black and smelly water, and even cause environmental problems such as floods, soil and groundwater pollution.

[0003] For example, Chinese patent CN222685571U discloses a river dredging device, including a horizontal frame, a movable box slidably connected to the horizontal frame, and a drive mechanism for driving the movable box to slide along the length of the horizontal frame. A collection box is connected to the movable box, and a sludge pump is installed inside the movable box. The inlet of the sludge pump is connected to a downward-extending suction pipe, and the outlet of the sludge pump is connected to an upward-extending discharge pipe that discharges sludge into the collection box. This invention, when cleaning sludge, allows the sludge pump inside the movable box to slide along the length of the horizontal frame through the control of the drive mechanism, thereby achieving automatic cleaning of sludge in a specific area. The cleaned sludge can be collected in the collection box. The operation is simple and efficient, avoiding impact on the surrounding environment and preventing any obstruction to road width or vehicle passage.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use, such as: the suction pipe of existing dredging devices is mostly designed with a fixed height, which cannot be dynamically adjusted according to the accumulation height of silt and foreign objects in the ditch; when the silt accumulation height in the ditch is low, the suction end of the suction pipe is easily higher than the silt surface, resulting in "empty suction", which requires frequent manual stops to adjust the height of the suction pipe and interrupt the dredging process; when the silt or foreign objects accumulation height is high, the suction end of the suction pipe is easily blocked directly, which not only damages the water pump, but also requires manual diving into the ditch or disassembling the equipment to clear the blockage. The operation is difficult and unsafe, and a single blockage treatment takes 30 to 60 minutes, which seriously affects the dredging progress.

[0005] In view of this, we propose a dredging device for environmental engineering and environmental remediation. Utility Model Content

[0006] The purpose of this utility model is to provide a dredging device for environmental engineering and environmental protection, so as to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a dredging device for environmental engineering and environmental remediation, comprising: The outer shell has a screw rotatably connected inside, and a sliding plate is threadedly connected to the screw. A motor is mounted on one outer surface of the outer shell. One end of the screw is fixedly connected to the output shaft of the motor. Two limiting rods are slidably connected inside the sliding plate. The left and right sides of the two limiting rods are respectively installed on the left and right inner walls of the outer shell. A water tank is fixedly mounted on the upper surface of the sliding plate. A support plate is fixedly mounted on the front of the water tank. A water pump is detachably mounted on the upper surface of the support plate. A drain pipe is detachably mounted on the drain end of the water pump. A suction pipe is detachably mounted on the inlet end of the water pump. The drain end of the drain pipe is placed inside the water tank. An adjustment component is installed at the outer end of the suction pipe and is used to adjust the position of the suction end of the suction pipe at the lower end of the outer casing.

[0008] In this technical solution, by activating the adjustment component to pull the suction pipe downwards, the sludge removal end of the device can come into close contact with the silt accumulated at the bottom of the ditch, thereby shortening the time spent by the device in the sludge removal process and thus improving the practicality of the device.

[0009] In the above technical solution, further, the adjusting component includes a fixed plate, an electric telescopic rod is fixedly installed on the lower surface of the fixed plate, a push plate is fixedly installed on the output end of the electric telescopic rod, a positioning hole is opened inside the push plate, the suction end of the water suction pipe is fixedly installed inside the positioning hole of the push plate, a plurality of rotating blocks are rotatably connected to the lower surface of the push plate, a fixed frame is fixedly installed at the bottom end of each of the plurality of rotating blocks, a roller is rotatably connected inside each of the plurality of fixed frames, an annular groove is opened on the outer surface of each of the two rollers, and a contact switch is fixedly installed on the inner wall of each of the plurality of annular grooves, an annular airbag is snapped into the inner wall of each of the plurality of annular grooves, and the inner wall of each of the plurality of annular airbags is respectively attached to the outer surface of the plurality of contact switches, and the plurality of contact switches are respectively wired to the control ends of the plurality of electric telescopic rods.

[0010] In this technical solution, the motor drives the screw to move the slide plate, water tank, and suction pipe left and right. This movement of the suction pipe simultaneously pulls the push plate and multiple rollers. When the silt or debris accumulated at the bottom of the ditch is higher than the rollers, the internal annular airbags of the rollers are compressed during rotation. The inner walls of these annular airbags then press against the outer surfaces of multiple contact switches, triggering the electric telescopic rod. The output end of the electric telescopic rod pulls the push plate, causing the suction pipe to retract upwards. When the compression of the annular airbags disappears, the electric telescopic rod stops. This allows the height of the suction pipe's suction end to automatically adjust according to the ditch's internal environment, thereby expanding the device's dredging range and improving its practicality. Meanwhile, by engaging the bottom end of the suction pipe with the positioning hole of the push plate, the height of the suction pipe can be adjusted, allowing the sludge removal end of the device to come into close contact with the silt accumulated at the bottom of the ditch, thus shortening the time spent on sludge removal and improving the device's practicality. By activating the electric telescopic rod to pull the push plate upward, the position of the lower surface of the push plate is adjusted to be parallel to the lower surface of the device, allowing the device to be placed stably on the ground, thus improving the device's practicality.

[0011] In the above technical solution, a positioning block one is fixedly installed on the upper surface of the water tank, the positioning block one is fitted onto the outer surface of the drain pipe, and a positioning block two is fixedly installed on the outer surface of the drain pipe, the positioning block two being located at the rear end of the positioning block one.

[0012] In this technical solution, the drain pipe is slidably connected inside the positioning block one, while the positioning block two is fixedly installed on the outer surface of the drain pipe. The positioning block one is located on the moving path of the positioning block two, which restricts the sliding path of the drain pipe inside the positioning block one. This restricts the moving path of the drain pipe's drain end by both positioning blocks two and one, eliminating the need for workers to manually support the drain pipe's drain end and reducing the need for workers to have prolonged close contact with the water tank. This improves the comfort of workers when operating the device and enhances its practicality.

[0013] In the above technical solution, a connecting pipe is detachably installed on the front of the water tank, and a valve is detachably installed on the outer end of the connecting pipe.

[0014] In this technical solution, by opening the valve, the sludge and sewage accumulated inside the water tank are discharged into the water tank along the connecting pipe, allowing workers to quickly clean the sludge accumulated inside the water tank, thereby shortening the time spent by workers in collecting or cleaning the sewage inside the water tank, thus improving the practicality of the device.

[0015] In the above technical solution, further, two sliding grooves are formed on the upper surface of the outer shell, and electromagnetic rods are installed inside the two sliding grooves of the outer shell. Two magnetic blocks are slidably connected to the outer surfaces of the two electromagnetic rods. L-shaped fixing frames are installed on the lower surfaces of the multiple magnetic blocks. Slider blocks are installed on the top of the inner walls of the multiple L-shaped fixing frames. Fixed pulley one is fixedly installed on the side of the multiple sliders near the ditch, and fixed pulley two is fixedly installed on the top of the inner walls of the multiple L-shaped fixing frames.

[0016] In this technical solution, by moving the outer shell, the lower surfaces of multiple fixed pulleys are brought into contact with the upper surface of the ditch edge. At this time, the positions of multiple fixed pulleys are adjusted and moved to the opening of the ditch. Then, by activating two electromagnetic rods, two magnetic blocks are driven to move multiple L-shaped fixing frames, which then bring the internal rollers of the multiple fixed pulleys into contact with the inner wall of the ditch. The multiple L-shaped fixing frames restrict the position of the outer shell at the upper end of the ditch, preventing the outer shell from tilting and falling into the ditch during use, thus improving the stability of the device during use. By pushing the outer shell, the internal rollers of the multiple fixed pulleys rotate at the outer end of the ditch, causing the multiple fixed pulleys to accelerate and move the outer shell, thereby reducing the labor and time required for workers to adjust and move the device at the upper end of the ditch, thus improving the practicality of the device.

[0017] In the above technical solution, furthermore, springs and damping rods are fixedly installed between the sliders and L-shaped fixing frames that are close to each other, and multiple springs are respectively sleeved on the outer ends of multiple damping rods.

[0018] In this technical solution, multiple damping rods push multiple sliders to slide inside the L-shaped fixed frame, and one end of multiple fixed pulleys continuously abuts against the inner wall of the ditch. This allows the damping rods to continuously and automatically adjust the position of the fixed pulleys, preventing them from failing to contact the uneven inner wall of the ditch during use. This improves the stability of the device when moving at the upper end of the ditch. Multiple sets of springs are respectively sleeved on the outer ends of the multiple damping rods. The springs have the characteristics of extension and contraction, which increases the resistance of the damping rods during extension and contraction. This prevents the damping rods from rapidly pushing the sliders and fixed pulleys to move, thus avoiding rigid collisions to the fixed pulleys.

[0019] In the above technical solution, the screw is located outside the drainage path of the connecting pipe, and a pull rod is hinged to the upper end of the outer casing.

[0020] In this technical solution, by positioning the screw outside the drainage path of the connecting pipe drain outlet, the wastewater discharged from the filter inside the water tank is less likely to come into contact with the screw. This avoids the small amount of wastewater discharge particles adhering to the outer surface of the screw during use, which could cause blockage of the sliding plate during adjustment. By pushing the pull rod to move the outer shell, the operator does not need to bend over when pushing the outer shell, thus improving the operator's comfort when moving the outer shell and improving the practicality of the device.

[0021] The beneficial effects of this utility model are: 1. This dredging device for environmental engineering and environmental remediation uses a motor-driven screw to move a sliding plate, water tank, and suction pipe left and right. As the suction pipe moves left and right, it simultaneously pulls a push plate and multiple rollers. When the accumulated silt or debris at the bottom of the ditch is higher than the rollers, multiple annular airbags inside the rollers are compressed during rotation. The inner walls of these annular airbags then press against the outer surfaces of multiple contact switches, triggering the activation of an electric telescopic rod. The output end of the electric telescopic rod pulls the push plate, causing the suction pipe to retract upwards. When the compression of the annular airbags disappears, the electric telescopic rod stops. This allows the height of the suction end of the suction pipe to be automatically adjusted according to the ditch environment, thereby expanding the dredging range of the device and improving its practicality.

[0022] 2. This dredging device for environmental engineering and environmental remediation involves moving the outer shell so that the lower surfaces of multiple fixed pulleys (first type) are brought into contact with the upper surface of the ditch edge. At this time, the positions of multiple fixed pulleys (second type) are adjusted and moved to the ditch opening. Then, by activating two electromagnetic rods, two magnetic blocks are driven to move multiple L-shaped fixing frames, causing the internal rollers of the multiple fixed pulleys (second type) to adhere to the inner wall of the ditch. The multiple L-shaped fixing frames restrict the position of the outer shell at the upper end of the ditch, preventing the outer shell from tilting and falling into the ditch during use, thus improving the stability of the device during operation. By pushing the outer shell, the internal rollers of the multiple fixed pulleys (first and second type) rotate at the outer end of the ditch, causing the multiple fixed pulleys (first and second type) to accelerate and adjust the movement of the outer shell. This reduces the labor and time required for workers to adjust and move the device at the upper end of the ditch, thus improving the practicality of the device. Attached Figure Description

[0027] Example 1: This example provides a dredging device for environmental engineering and environmental remediation, comprising: The outer shell 1 has a screw 11 rotatably connected inside it, and a sliding plate 30 is threadedly connected to the outside of the screw 11. A motor 12 is installed on one side of the outer surface of the outer shell 1. One end of the screw 11 is fixedly connected to the output shaft of the motor 12. Two limit rods 15 are slidably connected inside the sliding plate 30. The left and right sides of the two limit rods 15 are respectively installed on the left and right inner walls of the outer shell 1. A water tank 2 is fixedly installed on the upper surface of the sliding plate 30. A support plate 4 is fixedly installed on the front of the water tank 2. A water pump 3 is detachably installed on the upper surface of the support plate 4. A drain pipe 19 is detachably installed on the drain end of the water pump 3. A suction pipe 5 is detachably installed on the inlet end of the water pump 3. The drain end of the drain pipe 19 is placed inside the water tank 2. An adjustment component is installed at the outer end of the suction pipe 5 and is used to adjust the position of the suction end of the suction pipe 5 at the lower end of the outer casing 1. By activating the adjustment component, the suction pipe 5 is pulled downward, so that the sludge removal end of the device can come into close contact with the sludge accumulated at the bottom of the ditch, thereby shortening the time spent by the device in the sludge removal process and thus improving the practicality of the device.

[0028] Example 2: This example provides a dredging device for environmental engineering and environmental protection, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0029] The adjustment assembly includes a fixed plate 6, an electric telescopic rod 8 fixedly mounted on the lower surface of the fixed plate 6, a push plate 26 fixedly mounted on the output end of the electric telescopic rod 8, a positioning hole opened inside the push plate 26, the suction end of the suction pipe 5 fixedly mounted inside the positioning hole of the push plate 26, a plurality of rotating blocks 21 rotatably connected to the lower surface of the push plate 26, a fixed frame 22 fixedly mounted on the bottom end of each of the plurality of rotating blocks 21, a roller 23 rotatably connected inside each of the plurality of fixed frames 22, an annular groove opened on the outer surface of each of the two rollers 23, and a contact switch 25 fixedly mounted on the inner wall of each of the plurality of annular grooves, an annular airbag 24 snapped into the inner wall of each of the plurality of annular grooves, and the inner wall of each of the plurality of annular airbags 24 respectively attached to the outer surface of the plurality of contact switches 25, and the plurality of contact switches 25 respectively connected to the control ends of the plurality of electric telescopic rods 8 by wires; The motor 12 drives the screw 11 to move the slide plate 30, water tank 2, and suction pipe 5 left and right. When the suction pipe 5 moves left and right, it simultaneously pulls the push plate 26 and multiple rollers 23. When the silt or foreign objects accumulated at the bottom of the ditch are higher than the multiple rollers 23, the multiple annular airbags 24 inside the multiple rollers 23 are squeezed during rotation. The inner walls of the multiple annular airbags 24 are respectively attached to the outer surface of multiple contact switches 25, so that the multiple annular airbags 24 squeeze the multiple contact switches 25 to trigger the opening of the electric telescopic rod 8. At this time, the output end of the electric telescopic rod 8 pulls the push plate 26 to drive the suction pipe 5 to retract upward. When the compression of the outer end of the annular airbags 24 disappears, the electric telescopic rod 8 stops. This allows the height of the suction end of the suction pipe 5 to be automatically adjusted according to the internal environment of the ditch, thereby expanding the dredging range of the device and improving its practicality. Meanwhile, by engaging the bottom end of the suction pipe 5 with the positioning hole of the push plate 26, the height of the suction pipe 5 can be adjusted, allowing the sludge removal end of the device to come into close contact with the silt accumulated at the bottom of the ditch, thus shortening the time spent on sludge removal and improving the applicability of the device. By activating the electric telescopic rod 8 to pull the push plate 26 upward, the position of the lower surface of the push plate 26 is adjusted to be parallel to the lower surface of the device, allowing the device to be placed stably on the ground, thus improving the practicality of the device.

[0030] Example 3: This example provides a dredging device for environmental engineering and environmental protection, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0031] The water tank 2 has a positioning block 17 fixedly installed on its upper surface. Positioning block 17 is fitted onto the outer surface of the drain pipe 19. Positioning block 20 is fixedly installed on the outer surface of the drain pipe 19, and its position is located at the rear end of positioning block 17. The drain pipe 19 is slidably connected to the inside of positioning block 17. At this time, positioning block 20 is fixedly installed on the outer surface of the drain pipe 19. The position of positioning block 17 is located on the moving path of positioning block 20. Positioning block 20 restricts the sliding path of the drain pipe 19 inside positioning block 17. This restricts the moving path of the drain end of the drain pipe 19 by positioning block 20 and positioning block 17. As a result, the operator does not need to manually support the drain end of the drain pipe 19 and does not need to have close contact with the water tank 2 for a long time. This improves the operator's comfort when operating the device and thus improves the practicality of the device.

[0032] Example 4: This example provides a dredging device for environmental engineering and environmental protection, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0033] The water tank 2 is equipped with a connecting pipe 31, which is detached from the front. A valve 7 is detached from the outer end of the connecting pipe 31. By opening the valve 7, the sludge and sewage accumulated inside the water tank 2 are discharged through the connecting pipe 31, allowing workers to quickly clean the sludge accumulated inside the water tank 2. This reduces the time spent by workers collecting or cleaning the sewage inside the water tank 2, thus improving the practicality of the device.

[0034] Example 5: This example provides a dredging device for environmental engineering and environmental protection, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0035] The upper surface of the outer shell 1 has two sliding grooves, and an electromagnetic rod 14 is installed inside each of the two sliding grooves. Two magnetic blocks 16 are slidably connected to the outer surfaces of the two electromagnetic rods 14. An L-shaped fixing frame 9 is installed on the lower surface of the multiple magnetic blocks 16. A slider 13 is installed on the top of the inner wall of the multiple L-shaped fixing frames 9. A fixed pulley 10 is fixedly installed on the side of the multiple sliders 13 near the ditch. A fixed pulley 29 is fixedly installed on the top of the inner wall of the multiple L-shaped fixing frames 9. By moving the outer casing 1, the lower surfaces of multiple fixed pulleys 10 are brought into contact with the upper surface of the ditch. At this time, the positions of multiple fixed pulleys 29 are adjusted and moved to the opening of the ditch. Then, by activating two electromagnetic rods 14, two magnetic blocks 16 are driven to move multiple L-shaped fixing frames 9, which in turn bring the internal rollers of multiple fixed pulleys 29 into contact with the inner wall of the ditch. At this time, the multiple L-shaped fixing frames 9 restrict the position of the outer casing 1 at the upper end of the ditch, preventing the outer casing 1 from tilting and falling into the ditch during use, thus improving the stability of the device during use. By pushing the outer casing 1, the internal rollers of multiple fixed pulleys 10 and fixed pulleys 29 rotate at the outer end of the ditch, causing multiple fixed pulleys 10 and fixed pulleys 29 to accelerate and move the outer casing 1, thereby reducing the amount of labor and time spent by the workers when adjusting and moving the device at the upper end of the ditch, thus improving the practicality of the device.

[0036] Example 6: This example provides a dredging device for environmental engineering and environmental protection, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0037] Among them, springs 27 and damping rods 18 are fixedly installed between the sliders 13 and L-shaped fixing brackets 9 that are close to each other, and multiple springs 27 are respectively sleeved on the outer ends of multiple damping rods 18. Multiple damping rods 18 push multiple sliders 13 to slide inside the L-shaped fixed frame 9, continuously pressing one end of multiple fixed pulleys 29 against the inner wall of the ditch. This allows the damping rods 18 to continuously and automatically adjust the position of the fixed pulleys 29, preventing them from failing to contact the uneven inner wall of the ditch during use, thus improving the stability of the device when moving at the upper end of the ditch. Multiple sets of springs 27 are respectively sleeved on the outer ends of the multiple damping rods 18. The springs 27 have the characteristics of extension and contraction, which increases the resistance of the damping rods 18 when they extend and retract, preventing the damping rods 18 from rapidly pushing the sliders 13 and fixed pulleys 29 to move, thus avoiding rigid collisions to the fixed pulleys 29.

[0038] Example 7: This example provides a dredging device for environmental engineering and environmental protection, which, in addition to the technical solutions of the above examples, also has the following technical features.

[0039] The screw 11 is positioned outside the drainage path of the connecting pipe 31, and a pull rod 28 is hinged to the upper end of the outer casing 1. By positioning the screw 11 outside the drainage path of the drain outlet of the connecting pipe 31, the wastewater discharged from the filter inside the water tank 2 is less likely to come into contact with the screw 11, thus preventing a small amount of wastewater discharge particles from adhering to the outer surface of the screw 11 during use and causing blockage of the sliding plate 30 during the sliding adjustment process. By pushing the pull rod 28 to move the outer casing 1, the operator does not need to bend over when moving the outer casing 1, thereby improving the operator's comfort when moving the outer casing 1 and thus improving the practicality of the device.

[0040] Working principle: The motor 12 drives the screw 11 to move the slide plate 30, water tank 2, and suction pipe 5 left and right. When the suction pipe 5 moves left and right, it simultaneously pulls the push plate 26 and multiple rollers 23. When the silt or foreign objects accumulated at the bottom of the ditch are higher than the multiple rollers 23, the multiple annular airbags 24 inside the multiple rollers 23 are squeezed during rotation. The inner walls of the multiple annular airbags 24 are respectively attached to the outer surface of multiple contact switches 25, so that the multiple annular airbags 24 squeeze the multiple contact switches 25 to trigger the opening of the electric telescopic rod 8. At this time, the output end of the electric telescopic rod 8 pulls the push plate 26 to drive the suction pipe 5 to retract upward. When the compression of the outer end of the annular airbags 24 disappears, the electric telescopic rod 8 stops. This allows the height of the suction end of the suction pipe 5 to be automatically adjusted according to the internal environment of the ditch, thereby expanding the dredging range of the device and improving its practicality. Meanwhile, by moving the outer shell 1, the lower surfaces of multiple fixed pulleys 10 are brought into contact with the upper surface of the ditch. At this time, the positions of multiple fixed pulleys 29 are adjusted and moved to the opening of the ditch. Then, by activating two electromagnetic rods 14, two magnetic blocks 16 are driven to move multiple L-shaped fixing frames 9, so that the internal rollers of multiple fixed pulleys 29 are respectively attached to the inner wall of the ditch. At this time, the multiple L-shaped fixing frames 9 restrict the position of the outer shell 1 at the upper end of the ditch, preventing the outer shell 1 from moving, tilting and falling into the ditch during use, thus improving the stability of the device during use.
