Description

Technical Field

[0001] This application relates to the field of sludge treatment, specifically to a device for collecting underwater sludge. Background Technology

[0002] Rivers serve as important water conservancy channels for functions such as flood control, drought relief, and irrigation. To achieve these functions, it is essential to keep the river channels unobstructed. If too much silt accumulates on the riverbed, it will raise the riverbed and affect the river's ability to resist drought and drain water. Therefore, it is usually necessary to use silt removal devices to clean the silt from the riverbed.

[0003] A utility model patent with publication number CN217537124U discloses a sludge treatment device for environmental protection in water conservancy projects. The device includes a mobile frame and a support frame inside the mobile frame. A sludge pumping unit is located on one side of the lower end of the support frame. The sludge pumping unit includes a protective cover and a power fan located at the lower end of the protective cover. A sludge pumping pipe is located at the upper end of the protective cover. A mud-blocking filter screen is also installed inside the protective cover, and a mud-sweeping component is installed on the outside of the mud-blocking filter screen. This utility model solves the technical problem of inconvenient sludge extraction from the riverbed and the easy blockage of the sludge pumping port during extraction. The stirring fan is driven by a motor to rotate, stirring up the silt at the bottom of the river. Then, the sludge pumping unit on one side operates to extract the silt. During the sludge pumping operation, the mud and water drive the power fan to rotate, and the mud-sweeping component rotates in contact with the mud-blocking filter screen, preventing sludge from clogging the filter screen and affecting the sludge extraction. It also removes solid impurities.

[0004] The structure includes a movable frame with a support frame inside. During sludge cleaning, the sludge is stirred by a mixing fan and then pumped out through a suction pipe by a power fan. However, the sludge at the bottom of the water is prone to contain stones and other debris. When the mixing fan and power fan come into direct contact with these debris, they are easily damaged, resulting in low safety. Utility Model Content

[0005] To address the issue of low safety in existing equipment, this utility model provides a device for collecting underwater sludge.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] It also includes a lateral movement mechanism, which is installed on the upright frame;

[0009] It also includes a lifting mechanism, which is mounted on the mounting base.

[0010] Preferably, the lateral movement mechanism includes a motor and a screw. The screw is positioned between two sets of fixed blocks, with each end of the screw rotatably connected to one set of fixed blocks. Each fixed block has a mounting cavity. The motor is fixedly positioned within one set of mounting cavities. The output shaft of the motor is drivenly connected to one end of the screw. The mounting seat is threaded onto the screw. When the mounting seat and the vertical cylinder need to be laterally moved, the operator starts the motor, causing the output shaft of the motor to drive the screw to rotate, thereby moving the mounting seat and the vertical cylinder along the axial direction of the connecting rod. The operation is convenient.

[0011] Preferably, the lifting mechanism includes a second motor, a gear, and a limiting strip. The limiting strip is fixedly mounted on the vertical cylinder. The mounting base has a limiting groove that matches the limiting strip. The second motor is fixedly mounted on the top of the mounting base. The side wall of the limiting groove has a countersunk hole. The gear is rotatably mounted in the countersunk hole. The output shaft of the second motor is connected to the gear for transmission. The limiting strip has a toothed groove that meshes with the gear. When it is necessary to lift the vertical cylinder and the fixed cover, the operator starts the second motor on the mounting base, so that the output shaft of the second motor drives the gear to rotate. Then, through the meshing of the gear with the toothed groove on the limiting strip, the vertical cylinder is driven to move vertically. The operation is convenient.

[0012] Preferably, a motor three is fixedly installed on the top of the fixed cover, and a rotating shaft is rotatably installed inside the collection chamber. The output shaft of the motor three is connected to one end of the rotating shaft. Multiple sets of stirring strips are fixedly installed at intervals along the circumference of the rotating shaft. When the sludge at the bottom of the water is highly viscous, the operator starts the motor three, which drives the rotating shaft to rotate, thereby causing the stirring strips on the rotating shaft to stir the sludge in the collection chamber, which facilitates the suction pump to suck up the sludge. In addition, the motor three is a waterproof motor, ensuring normal operation of the motor three in the water.

[0013] Preferably, the number of rotating shafts is multiple and they are spaced apart in the collection chamber. By setting multiple sets of rotating shafts, the sludge in the collection chamber can be stirred at multiple points, ensuring normal suction of the sludge.

[0014] Preferably, a barrier net is fixedly installed at the rear end of the collection chamber. The barrier net at the rear end of the collection chamber ensures that the suction pump can completely suck up the sludge in the collection chamber, preventing the sludge from re-entering the bottom of the water from the rear end of the collection chamber.

[0015] Preferably, a control terminal is fixedly installed on the support frame. Motor 1, Motor 2, Motor 3 and the suction pump are all electrically connected to the control terminal through wires.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1-3 As shown in the figure, this utility model embodiment discloses a bottom sludge collection device, including a frame 1, a horizontal movement mechanism, and a lifting mechanism. The number of frames 1 is two sets arranged at intervals. A fixing block 101 is fixedly installed on one side of the frame 1. Multiple sets of connecting rods 2 are arranged between the two sets of frames 1. The two ends of the connecting rods 2 are respectively fixedly connected to a set of fixing blocks 101. A mounting seat 3 is slidably sleeved on the connecting rod 2. A vertical cylinder 4 is arranged on one side of the mounting seat 3. A fixing cover 5 is fixedly installed at the bottom of the vertical cylinder 4. A collection chamber 501 is provided inside the fixing cover 5. The fixing cover 5 has inclined surfaces on both sides of the front end of the collection chamber 501. Multiple sets of partitions 502 are fixedly fixedly arranged at intervals along the length direction of the inclined surfaces of the fixing cover 5. A suction pipe 503 communicating with the collection chamber 501 is provided inside the vertical cylinder 4. A suction pump 6 is fixedly installed at the top of the vertical cylinder 4. One end of the suction pipe 503 is connected to the suction pump 6. The horizontal movement mechanism is arranged on the frame 1, and the lifting mechanism is arranged on the mounting seat 3.

[0025] In at least one embodiment, the lateral movement mechanism includes a motor and a screw 8. The screw 8 is disposed between two sets of fixed blocks 101, and each end of the screw 8 is rotatably connected to a set of fixed blocks 101. The fixed blocks 101 are provided with mounting cavities. The motor is fixedly disposed in one of the mounting cavities. The output shaft of the motor is drivenly connected to one end of the screw 8. The mounting seat 3 is threaded onto the screw 8. When it is necessary to move the mounting seat 3 and the vertical cylinder 4 laterally, the operator starts the motor, so that the output shaft of the motor drives the screw 8 to rotate, thereby driving the mounting seat 3 and the vertical cylinder 4 to move along the axial direction of the connecting rod 2. The operation is convenient.

[0026] In at least one embodiment, the lifting mechanism includes a second motor 9, a gear, and a limiting strip 401. The limiting strip 401 is fixedly mounted on the vertical cylinder 4. The mounting base 3 has a limiting groove that matches the limiting strip 401. The second motor 9 is fixedly mounted on the top of the mounting base 3. The side wall of the limiting groove has a countersunk hole. The gear is rotatably mounted in the countersunk hole. The output shaft of the second motor 9 is connected to the gear drive. The limiting strip 401 has a toothed groove 402 that meshes with the gear. When it is necessary to lift the vertical cylinder 4 and the fixed cover 5, the operator starts the second motor 9 on the mounting base 3, so that the output shaft of the second motor 9 drives the gear to rotate. Then, through the meshing of the gear with the toothed groove 402 on the limiting strip 401, the vertical cylinder 4 is driven to move vertically. The operation is convenient.

[0027] In at least one embodiment, a motor 7 is fixedly installed on the top of the fixed cover 5, and a rotating shaft 701 is rotatably installed inside the collection chamber 501. The output shaft of the motor 7 is connected to one end of the rotating shaft 701. Multiple sets of stirring strips are fixedly installed at intervals along the circumference of the rotating shaft 701. When the sludge at the bottom of the water is highly viscous, the operator starts the motor 7, which drives the rotating shaft 701 to rotate. This causes the stirring strips on the rotating shaft 701 to stir the sludge in the collection chamber 501, facilitating the suction pump 6 to suck up the sludge. Furthermore, the motor 7 is a waterproof motor, ensuring normal operation of the motor 7 in the water.

[0028] In at least one embodiment, the number of rotating shafts 701 is multiple and they are spaced apart in the collection chamber 501. By setting multiple sets of rotating shafts 701, the sludge in the collection chamber 501 can be stirred at multiple points to ensure normal suction of the sludge.

[0029] In at least one embodiment, a barrier net 504 is fixedly provided on the rear end of the collection chamber 501 of the fixed cover 5. By providing the barrier net 504 at the rear end of the collection chamber 501, it is ensured that the suction pump 6 can completely suck up the sludge in the collection chamber 501, and prevent the sludge from re-entering the bottom of the water from the rear end of the collection chamber 501.

[0030] In at least one embodiment, a control terminal is fixedly installed on the support frame 1. Motor 1, Motor 2 9, Motor 3 7 and the suction pump 6 are all electrically connected to the control terminal through wires. The operator can conveniently adjust the working status of each part through the control terminal, making the operation convenient.

[0031] When cleaning the sludge at the bottom of the water, workers place two sets of upright frames 1 on both sides of the water body, so that the mounting base 3 between the two sets of upright frames 1 is above the water body. The bottom of the upright frame 1 is equipped with pulleys to facilitate the movement of the upright frame 1. Then, workers use a lateral movement mechanism to move the mounting base 3 and the vertical cylinder 4 laterally along the connecting rod 2 to the area to be cleaned. During the movement, multiple sets of connecting rods 2 can limit the movement of the mounting base 3 to ensure the stability of the movement of the mounting base 3. Then, a lifting mechanism drives the vertical cylinder 4 and the bottom fixing cover 5 to descend, so that the fixing cover 5 descends into the sludge at the bottom of the water. Then, workers start the suction pump 6 at the top of the vertical cylinder 4, so that the suction pump 6 passes through the suction pipe 50 3. The sludge inside the fixed cover 5 is sucked out. The operator connects the outlet of the suction pump 6 to the sludge discharge pipe to discharge the sludge to the outside. By setting inclined surfaces on both sides of the front end of the fixed cover 5 and fixing multiple sets of baffles 502 along the length of the inclined surfaces, when the fixed cover 5 moves, it collides with the stones deposited in the sludge. The stones can move to the outside of the fixed cover 5 along the baffles 502 on both sides of the inclined surfaces, avoiding the stones from entering the collection chamber 501 and avoiding blockage of the suction pipe 503, thus ensuring the safety of the equipment. In addition, the baffles 502 at the front end of the fixed cover 5 can perform preliminary cutting of the sludge entering the collection chamber 501, ensuring that the suction pump 6 can smoothly suck out the sludge.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 application.
