Description

Technical Field

[0001] The invention belongs to the technical field of waterworks of water plants and relates to a water tank cleaning device of a water plant. Background Art

[0002] A water plant's sedimentation tank is a structure that uses natural sedimentation or coagulation to remove suspended matter from the water, achieving the goal of water purification. Sedimentation is a crucial step in the production of tap water. It occurs in a large rectangular tank, where muddy water flows through one end, slowly flows through the tank, and then flows out of a clean water diversion channel at the other end. A large amount of sediment needs to settle in the sedimentation tank. If this sediment is not cleaned promptly, it will accumulate, affecting the normal operation of the sedimentation tank and even causing water quality deterioration. Furthermore, the area where the water surface contacts the side walls of the sedimentation tank provides an ideal environment for the attachment and growth of dirt and moss. If not cleaned promptly, this will also cause water quality deterioration.

[0003] The existing sludge removal vehicle that is often used to clean the bottom of the sedimentation tank can only simply remove the sludge, but cannot clean the dirt and moss on the bottom and side walls of the sedimentation tank, which will affect the water quality.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following is combined with Figures 1 to 7 The specific embodiments of the present invention are described in further detail.

[0030] Depend on Figures 1 to 7 As shown, the present invention includes a movable mobile frame 1. In order to facilitate the cleaning of the sedimentation tank of the sedimentation tank, a suction sleeve 2 is fixedly connected to the upper side of the mobile frame 1. The upper side of the suction sleeve 2 is connected to a suction pipe 3 for providing negative pressure to the interior of the mobile frame 1. A plurality of rotatable moving wheels 4 are provided on the lower side of the mobile frame 1. Two rotatable cleaning sleeves 5 for cleaning the side walls of the water tank are provided on the left and right sides of the mobile frame 1 respectively. A movable plate 6 that can move up and down is provided inside the suction sleeve 2. The angle of each cleaning sleeve 5 changes with the up and down movement of the movable plate 6.

[0031] It should be noted that the water tank of the water plant refers to the sedimentation tank of the horizontal flow sedimentation tank. The sedimentation tank is set in the middle of the horizontal flow sedimentation tank, perpendicular to the direction of water flow, and generally multiple sedimentation tanks are set; the end of the suction pipe 3 away from the mobile frame 1 is connected to the filter mechanism and the water pump, which provides negative pressure to the interior of the mobile frame 1 by pumping water, and filters and discharges the extracted liquid;

[0032] When in use, it is necessary to first drain part of the water inside the horizontal flow sedimentation tank so that the water depth at the sedimentation tank is not less than one meter, and continue to input water at the water inlet end of the horizontal flow sedimentation tank to ensure the liquid level. Then the mobile rack 1 can be directly placed in the sedimentation tank. At this time, under the action of the water pump at one end of the suction pipe 3, the liquid inside the mobile rack 1 can be sucked. At this time, the moving wheel 4 is in contact with the sedimentation tank. Under the support of the moving wheel 4, the liquid inside the sedimentation tank enters the interior of the mobile rack 1 through the gap between the mobile rack 1 and the sedimentation tank, and is then sucked out through the suction sleeve 2 and the suction pipe 3. Therefore, according to Bernoulli's principle, the movable frame 1 has a tendency to press the bottom wall of the sedimentation tank downward under the action of water flow, so that the contact between the movable wheel 4 and the bottom wall of the sedimentation tank can be closer. In addition, under the suction action of the water pump, the movable plate 6 has a tendency to move upward under the action of water flow, which will drive each cleaning sleeve 5 to have a tendency to rotate downward, so that the cleaning sleeve 5 can fit more closely to the side wall of the sedimentation tank or the bottom wall of the sedimentation tank. During the cleaning process, the rotation of the movable wheel 4 can drive the movable frame 1 to move, and then the sedimentation tank is cleaned by the rotating cleaning sleeve 5.

[0033] Further, by Figures 2 to 5 As shown, in order to facilitate cleaning of the side wall of the water tank, a fixed rod 7 is fixedly connected to each of the left and right sides of the mobile frame 1. A rotation groove is opened at the front and rear ends of each fixed rod 7. A rotating sleeve 9 is rotatably connected to the inside of each rotating groove. A positioning rod 10 is fixedly connected to the outside of each rotating sleeve 9. Each cleaning sleeve 5 is sleeved on the outside of the positioning rod 10.

[0034] Further, by Figures 2 to 5 As shown, in order to achieve a better cleaning effect, each cleaning sleeve 5 is fixedly connected to a first bevel gear 11 on one side close to the rotating sleeve 9, and an outer sleeve of the fixed rod 7 is provided with an adjusting sleeve 12. The front and rear ends of the adjusting sleeve 12 are respectively fixedly connected to the corresponding rotating sleeve 9, and the middle part of the adjusting sleeve 12 is fixedly connected to a first motor 13. The output shaft of the first motor 13 is fixedly connected to a power rod 14. Each first bevel gear 11 is meshed with a second bevel gear 15 on the side away from the rotating sleeve 9, and each second bevel gear 15 is fixedly connected to the power rod 14.

[0035] It should be noted that the first motor 13 is a double-output shaft motor, and the output shafts on both sides thereof are each connected to a power rod 14;

[0036] Further, by Figures 2 to 5 As shown, in order to be able to clean the blind corners of the sink, a conical brush 16 is fixedly connected to the outside of the cleaning sleeve 5; the conical brush 16 is designed to be narrow at the top and wide at the bottom. Under the action of the inclined positioning rod 10, the conical brush 16 can be made to fit the inner wall of the sink more closely;

[0037] During use, under the action of the adjusting sleeve 12, the two rotating sleeves 9 on the front and rear sides of the adjusting sleeve 12 can be driven to rotate together. Therefore, rotating the adjusting sleeve 12 can adjust the angle of the two positioning rods 10 on the same side, thereby adjusting the angle of the cleaning sleeve 5. After starting the first motor 13, the first motor 13 drives the two second bevel gears 15 to rotate through the two power rods 14, and then drives the first bevel gear 11 to rotate, thereby driving each cleaning sleeve 5 to rotate through the first bevel gear 11, and then cleaning is performed through each conical brush 16.

[0038] Further, by Figures 2 to 6 As shown, in order to automatically fit the side wall of the water tank for cleaning, the inner wall of the suction sleeve 2 is provided with a plurality of sliding grooves 17, and the outer side of the movable plate 6 is fixedly connected with sliding blocks 18 corresponding to the sliding grooves 17 one by one. Each sliding block 18 is slidably connected to the corresponding sliding groove 17, and a plurality of through holes 19 are provided in the middle of the movable plate 6;

[0039] Further, by Figures 2 to 6 As shown, in order to reduce the overall cost of the device, a pulley 20 is fixedly connected to the middle of each adjusting sleeve 12, and a steel wire rope 21 is fixedly connected to the outer side of each pulley 20. The end of each steel wire rope 21 away from the pulley 20 passes through the side wall of the movable frame 1 and is fixedly connected to the corresponding sliding block 18. The movable plate 6 moves up and down to form a structure in which the pulley 20 rotates;

[0040] It should be noted that the steel wire rope 21 is a flexible steel wire rope 21, which is a prior art and will not be described in detail here. Furthermore, guide wheels are provided at the positions inside the mobile frame 1 corresponding to the bending positions of the steel wire rope 21.

[0041] During use, under the action of the upward flowing water inside the suction sleeve 2, the movable plate 6 will be driven to move upward, and then the movable plate 6 will pull the upper end of the wire rope 21 to move upward, and then the lower end of the wire rope 21 will pull the pulley 20 to rotate, and the adjusting sleeve 12 will be driven to rotate through the pulley 20, so that the adjusting sleeve 12 drives the positioning rod 10 to move away from the movable frame 1.

[0042] Further, by Figures 2 to 6 As shown, in order to increase the function of pre-processing foreign matter, a fixed block 22 is fixedly connected to the upper side of the movable plate 6, a second motor 23 is fixedly connected to the interior of the fixed block 22, and a cutting frame 24 is rotatably connected to the lower side of the movable plate 6. The output shaft of the second motor 23 passes through the movable plate 6 and is fixedly connected to the cutting frame 24. A plurality of cutting blades 25 are fixedly connected to the outer side of the cutting frame 24;

[0043] During use, after starting the second motor 23, the second motor 23 will drive the cutting knife 25 to rotate through the cutting frame 24, thereby cutting off foreign matter blocking the lower side of the movable plate 6, thereby increasing the service life of the subsequent filtering system and the water pump.

[0044] Further, by Figure 2 and Figure 7 As shown, in order to increase the adsorption force of the device on the bottom of the sedimentation tank, a rotating shaft 26 is fixedly connected to the middle of each moving wheel 4, and a bearing seat 27 is rotatably connected to the left and right ends of each rotating shaft 26. A directional rod 28 is fixedly connected to the upper side of each bearing seat 27. An directional groove 29 is opened inside the movable frame 1 corresponding to the upper side of each directional rod 28. A return spring 30 is provided inside each directional groove 29, and the lower side of each return spring 30 abuts against the upper side of the corresponding directional rod 28.

[0045] During use, when the device is placed in the water tank, under the action of the return spring 30, each moving wheel 4 is in an extreme position away from the moving frame 1, so that it can contact the bottom of the sedimentation tank earlier as the moving frame 1 moves downward, reducing the risk of the device tipping over. When there is negative pressure inside the moving frame 1, the moving frame 1 will be subjected to continuous downward force, so the return spring 30 will be compressed at this time, and then the directional rod 28 will drive each bearing seat 27 to move upward relative to the moving frame 1, and the moving wheel 4 will move upward relative to the moving frame 1, reducing the gap between the bottom of the moving frame 1 and the bottom of the sedimentation tank, which can increase the downward force of the moving frame 1 under the action of negative pressure.

[0046] Further, by Figure 2 and Figure 7 As shown, in order to achieve better device movement efficiency, a third motor 31 is provided on the side of each moving wheel 4 and is fixedly connected to the corresponding bearing seat 27. The output shaft of each third motor 31 passes through the corresponding bearing seat 27 and is fixedly connected to the corresponding rotating shaft 26.

[0047] When in use, each third motor 31 drives the corresponding rotating shaft 26 to rotate, so that each moving wheel 4 can rotate independently, thereby facilitating the movement of the entire control device;

[0048] It should be further explained that the outer side of the rotating wheel is also provided with a crawler or pattern for walking in the mud, which can increase the friction between the rotating wheel and the bottom of the sedimentation tank, thereby facilitating the movement of the device at the bottom of the sedimentation tank;

[0049] Further, by Figures 4 and 5As shown, in order to increase the cleaning efficiency of the bottom of the sedimentation tank, a second cleaning mechanism for cleaning the front and rear sides of the mobile frame 1 is also included, and the second cleaning mechanism includes a vibrating block 32 slidably connected to the mobile frame 1, and a limiting groove 33 is respectively provided on the front and rear sides of the mobile frame 1, and each vibrating block 32 is slidably connected to the corresponding limiting groove 33, and a disassembly groove 34 is provided at the lower end of each vibrating block 32, and a second cleaning brush 35 is detachably connected to the side of each vibrating block 32 away from the limiting groove 33 through the disassembly groove 34, and two transmission blocks 36 are fixedly connected to the upper side of the vibrating block 32, and a cam 37 is provided between the transmission blocks 36, and a fourth motor 38 is fixedly connected to the front and rear sides of the interior of the mobile frame 1, and the output shaft of each fourth motor 38 is fixedly connected to the corresponding cam 37;

[0050] It should be noted that the limiting groove 33 is trapezoidal in shape, wide inside and narrow outside, which enables the vibration block 32 to slide left and right along the limiting groove 33 without falling off;

[0051] When in use, after starting the fourth motor 38, the output shaft of the fourth motor 38 drives the corresponding transmission block 36 to move through the cam 37, thereby driving the vibration block 32 to move. Under the action of the two transmission blocks 36 on both sides of the cam 37, the vibration block 32 can continue to reciprocate left and right, thereby causing the vibration block 32 to drive the second cleaning brush 35 to reciprocate left and right, and the bottom of the sedimentation tank is cleaned by the second cleaning brush 35.

[0052] It should be further explained that the outside of the suction pipe 3 is wrapped with a power supply cable for powering the entire device and a data cable for data transmission, as well as a recovery rope for recovering the entire device. The first motor 13 is a deep-water waterproof double-shaft permanent magnet motor with a model of SF120H48V-420. The second motor 23, the third motor 31 and the fourth motor 38 are all underwater motors, such as the underwater motor model SAM002 of Shanghai Jingwei Electronics Co., Ltd., which are all existing technologies and will not be described in detail here. The device is also provided with a motor controller (MCU) for controlling the rotation direction, rotation speed, and start and stop time of the first motor 13, the second motor 23, the third motor 31 and the fourth motor 38, such as a stepper motor controller with a model of RS PRO, or a PLC controller, which are all existing technologies and will not be described in detail here. The first motor 13, the second motor 23, the third motor 31 and the fourth motor 38 are all connected to the power supply cable and the data cable, and the other end of the data cable is connected to the motor controller.

[0053] When the present invention is used, it is necessary to first discharge part of the water inside the horizontal flow sedimentation tank so that the water depth at the sedimentation tank position is not less than one meter, and continuously input water at the water inlet end of the horizontal flow sedimentation tank to ensure the liquid level. After that, the mobile frame 1 can be directly placed in the sedimentation tank. At this time, under the action of the water pump at one end of the suction pipe 3, the liquid inside the mobile frame 1 can be sucked. At this time, the moving wheel 4 is in contact with the sedimentation tank. Under the support of the moving wheel 4, the liquid inside the sedimentation tank enters the interior of the mobile frame 1 through the gap between the mobile frame 1 and the sedimentation tank, and is then extracted through the suction sleeve 2 and the suction pipe 3. Therefore, according to Bernoulli's principle, the mobile frame 1 has a tendency to press the bottom wall of the sedimentation tank downward under the action of water flow, so that the contact between the moving wheel 4 and the bottom wall of the sedimentation tank can be made closer. In addition, under the pumping of the water pump, the liquid inside the sedimentation tank enters the interior of the mobile frame 1 through the gap between the mobile frame 1 and the sedimentation tank, and is then extracted through the suction sleeve 2 and the suction pipe 3. Under the action of suction, the movable plate 6 has a tendency to move upward under the action of water flow, which will drive each cleaning sleeve 5 to have a tendency to rotate downward, so that the cleaning sleeve 5 can be more closely fitted to the side wall of the sedimentation tank or the bottom wall of the sedimentation tank. During the cleaning process, the rotation of the movable wheel 4 can drive the movable frame 1 to move, and then the sedimentation tank is cleaned by the rotating cleaning sleeve 5; after starting the fourth motor 38, the output shaft of the fourth motor 38 drives the corresponding transmission block 36 to move through the cam 37, thereby driving the vibration block 32 to move. Under the action of the two transmission blocks 36 on both sides of the cam 37, the vibration block 32 can continue to reciprocate left and right, so that the vibration block 32 drives the second cleaning brush 35 to reciprocate left and right, and the bottom of the sedimentation tank is cleaned by the second cleaning brush 35.

[0054] The present invention has a novel structure, ingenious conception, and simple and convenient operation. Through this design, it is effectively facilitated to clean the sedimentation tank of the sedimentation tank, facilitates the cleaning of the side walls of the water tank, achieves a better cleaning effect, can clean the dead corners of the water tank, can automatically adhere to the side walls of the water tank for cleaning, reduces the overall use cost of the device, increases the function of pre-treating foreign matter, increases the adsorption force of the device on the bottom of the sedimentation tank, achieves better device movement efficiency, and increases the cleaning efficiency of the bottom of the sedimentation tank.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
