Description

Technical Field

[0001] The invention relates to the technical field of solar collector tube cleaning, and in particular to a solar collector tube scale cleaning machine and a use method thereof. Background Art

[0002] As the energy crisis intensifies and people's awareness of environmental protection and energy conservation increases, solar water heaters have been widely used as a device that utilizes renewable energy. It absorbs solar radiation energy through solar collector tubes, converts light energy into heat energy, heats the water in the tubes, and provides hot water for families. However, water contains various minerals, such as calcium and magnesium ions. During the heating process, these minerals will precipitate and form scale on the inner wall of the solar collector tube.

[0003] Existing patent (publication number: CN 109945524 B) A solar collector tube scale cleaning machine is disclosed, comprising a fixing device, a collector tube clamping device, a sewage recovery device and a cleaning device, wherein the fixing device comprises a fixing rod, a first clamping plate rotatably connected to the fixing rod, a clamping plate symmetrically arranged with the first clamping plate, a first elastic member sleeved on the fixing rod and a plurality of elastic protrusions uniformly arranged on the first clamping plate, one end of the first elastic member is fixed on the first clamping plate, and the other end is fixed on the second clamping plate, and the first clamping plate and the second clamping plate are both curved in an arc shape, and the sewage recovery device comprises a collecting mechanism, a filtering mechanism and a transport mechanism. The above-mentioned solar collector tube scale cleaning machine can collect sewage flowing out of the collector tube through the collecting mechanism, and then filter and remove the scale in the sewage through the filtering mechanism, thereby completing the water purification, facilitating subsequent reuse, and greatly saving water resources. However, cleaning by continuously inserting the cleaning tube is not only inefficient but also difficult to clean out all the internal scale. The scale cleaned remains in the interior of the collector tube, which will also result in the consequence of incomplete cleaning. Therefore, a solar collector tube scale cleaning machine is needed.

[0008] Preferably, the screw is meshed with the large gear, and the screw is rotatably connected to the surface of the workbench at the same time. The other end of the connecting rod is rotatably connected to the side of the Y-shaped clamping rod, and the upper end of the Y-shaped clamping rod is slidably connected to the inner upper end of the cleaning seat.

[0009] Preferably, the rotating rod is fixedly connected to the side of the threaded rod, and the two sides of the arc-shaped brush are slidably connected inside the circulation chute through a limiting groove.

[0010] Preferably, the piston rod is slidably connected inside the piston storage barrel, and the pinion gear is meshed with the half gear.

[0011] A method for using a solar collector tube scale cleaning machine comprises the following steps: S1. First, fix the heat collecting tube to be cleaned at the front end of the hollow rod, and then start the driving motor. After the driving motor is started, it drives the screw to rotate, and when the screw rotates, it drives the connecting rod to rotate. When the connecting rod rotates, it drives the half gear fixed at the front end to rotate. When the half gear rotates, it first meshes with the pinion gear, driving the pinion gear to rotate forward. When the half gear separates from the pinion gear, it meshes with the teeth on the hollow roller, which will drive the pinion gear to rotate reversely. S2. When the pinion rotates forward, it drives the threaded rod to rotate. The threaded rod rotates inside the hollow rod, and the threaded groove inside the hollow rod drives the hollow rod to move forward through the transverse slide grooves opened on both sides, so that the hollow rod is limited between the limit slide rails, so that the hollow rod moves forward horizontally and moves toward the inside of the heat collecting tube, and at the same time drives the arc brush on the surface to enter the inside of the heat collecting tube to clean the inside of the heat collecting tube. The staggered arrangement of the arc brushes can clean the inside of the heat collecting tube in all directions; S3. When the threaded rod rotates, the spline rod at the front end is driven to rotate at the same time. When the spline rod rotates, the rotating rod at the front end of the hollow rod is driven to rotate at the same time. When the hollow rod moves forward, it drives the rotating rod connected to the internal rotation to move forward at the same time. The rotating rod moves forward on the surface of the spline rod. When the rotating rod rotates, the circulating chute opened on the surface is driven to rotate at the same time. When the circulating chute rotates, the arc brush connected to it is driven to swing left and right along the routes of different angles on both sides of the circulating chute. Different from the state in which the hollow rod drives the arc brush to extend horizontally for cleaning, the diameter of the arc brush is changed during the swinging to better fit the inner wall of the heat collecting tube. S4. When the pinion gear reverses, it drives the threaded rod to rotate in the opposite direction, and at the same time drives the hollow rod to move backward horizontally and move outward from the inside of the heat collecting tube, and at the same time drives the arc-shaped brush on the surface to pull out the scale and other debris cleaned inside the heat collecting tube. At the same time, when the hollow rod moves backward, it drives the rotating rod connected to the internal rotation to move backward at the same time. The rotating rod will move backward on the surface of the spline rod, and when the rotating rod rotates, it drives the circulation chute opened on the surface to rotate in the opposite direction at the same time. When the circulation chute rotates, it drives the arc-shaped brush connected to it to swing left and right in the opposite direction along the routes of different angles on both sides of the circulation chute, so as to better bring out the scale and other debris from the inside of the heat collecting tube. At the same time, when the pinion gear rotates forward and reversely, it drives the hollow rod to form a back and forth reciprocating motion, so that continuous cleaning can be performed; S5. At the same time, when the screw rotates, it drives the meshing large gear to rotate, and when the large gear rotates, it drives the eccentric wheels on both sides to rotate. The rotation of the eccentric wheels drives the side rotations to connect the connecting rods to push or pull the Y-shaped clamp rod to move back and forth on the upper end of the cleaning seat. When the Y-shaped clamp rod moves back and forth, it drives the annular groove to move back and forth. When the annular groove moves back and forth, it drives the sleeve rod to move back and forth on the surface of the connecting rod. When the sleeve rod moves, it drives the fixedly connected piston rod to reciprocate back and forth inside the piston storage barrel, and injects the acidic liquid inside the piston storage barrel into the telescopic hose, and decomposes and removes the scale inside the heat collecting pipe through the liquid outlet. After the acidic liquid in the piston storage barrel is used up, it is added through the liquid filling port, and the movement of the hollow rod drives the liquid outlet to move back and forth through the telescopic hose.

[0012] In the present invention, the threaded groove inside the hollow rod drives the hollow rod to move forward through the horizontal sliding grooves opened on both sides, so that the hollow rod is limited between the limiting slide rails, so that the hollow rod moves forward horizontally and moves toward the inside of the heat collecting tube, and at the same time drives the arc-shaped brush on the surface to enter the inside of the heat collecting tube to clean the inside of the heat collecting tube. The staggered arrangement of the arc-shaped brushes can clean the inside of the heat collecting tube in all directions, and at the same time reserve space for the discharge of debris such as scale.

[0013] In the present invention, the circulation chute opened on the surface is driven to rotate simultaneously by the rotation of the rotating rod. When the circulation chute rotates, the arc brush slidably connected thereto is driven to swing left and right along the routes of different angles on both sides of the circulation chute. This is different from the cleaning state in which the hollow rod drives the arc brush to extend horizontally. At the same time, the diameter of the arc brush is changed during the swinging, so that it better fits the inner wall of the heat collecting tube and increases the friction with the inner wall of the heat collecting tube, thereby further improving the cleaning ability and increasing the cleaning efficiency.

[0014] In the present invention, when the Y-shaped clamping rod moves forward and backward, the annular groove is driven to move forward and backward. When the annular groove moves forward and backward, the sleeve rod is driven to move forward and backward on the surface of the connecting rod. When the sleeve rod moves, the fixedly connected piston rod is driven to reciprocate forward and backward inside the piston storage barrel. The acidic liquid inside the piston storage barrel is injected into the telescopic hose, and the scale is decomposed and removed inside the heat collecting pipe through the liquid outlet, thereby further improving the cleaning efficiency.

First, fix the heat collecting tube to be cleaned at the front end of the hollow rod 51, and then start the driving motor 32. After the driving motor 32 is started, it drives the screw 33 to rotate. When the screw 33 rotates, it drives the connecting rod 310 to rotate. When the connecting rod 310 rotates, it drives the half gear 44 fixed at the front end to rotate. When the half gear 44 rotates, it first meshes with the pinion 48, driving the pinion 48 to rotate forward.

The staggered arrangement of the arc brushes 55 can clean the inside of the heat collecting tube in an all-round manner, and at the same time reserve space for the discharge of debris such as scale; S3. When the threaded rod 52 rotates, the spline rod 56 at the front end is driven to rotate at the same time.

The rotating rod 57 will move backward on the surface of the spline rod 56, and when the rotating rod 57 rotates, it drives the circulation chute 58 opened on the surface to rotate in the opposite direction at the same time. When the circulation chute 58 rotates, it drives the arc-shaped brush 55 slidably connected thereto to swing left and right in the opposite direction along the routes of different angles on both sides of the circulation chute 58, so as to better bring out the scale and other debris from the inside of the heat collecting tube, which not only increases the cleaning efficiency but also increases the efficiency of discharging the scale, and prevents the scale from remaining inside the heat collecting tube. At the same time, when the pinion 48 rotates forward and reversely, it will drive the hollow rod 51 to form a reciprocating motion back and forth, so that the cleaning can be continuously performed; S5. At the same time, when the screw 33 rotates, it drives the meshing large gear 34 to rotate. When the large gear 34 rotates, it drives the eccentric wheels 35 on both sides to rotate. The rotation of the eccentric wheels 35 drives the connecting rod 36 connected to the side rotation to push or pull the Y-shaped clamping rod 39 to move back and forth on the upper end of the cleaning seat 1. When the Y-shaped clamping rod 39 moves back and forth, it drives the annular groove 38 to move back and forth. When the annular groove 38 moves back and forth, it drives the sleeve rod 37 to move back and forth on the surface of the connecting rod 310. When the sleeve rod 37 moves, it drives the fixedly connected piston rod 45 to reciprocate back and forth inside the piston storage barrel 46, and injects the acidic liquid inside the piston storage barrel 46 into the telescopic hose 49. Through the liquid outlet 410 inside the heat collecting pipe, the scale is decomposed and removed, and the cleaning efficiency is further improved. After the acidic liquid in the piston storage barrel 46 is used up, it is added through the liquid injection port 47, and the movement of the hollow rod 51 drives the liquid outlet 410 to move back and forth through the telescopic hose 49.

When the pinion (48) rotates forward, it drives the threaded rod (52) to rotate. The threaded rod (52) rotates inside the hollow rod (51). The threaded groove (59) inside the hollow rod (51) drives the hollow rod (51) to move forward through the transverse slide grooves (53) provided on both sides, so that the hollow rod (51) is limited between the limit slide rails (2). The hollow rod (51) moves forward horizontally and moves toward the inside of the heat collecting tube. At the same time, the arc-shaped brush (55) on the surface is driven to enter the inside of the heat collecting tube to clean the inside of the heat collecting tube. The staggered arrangement of the arc-shaped brushes (55) can clean the inside of the heat collecting tube in all directions. S3, when the threaded rod (52) rotates, the spline rod (56) at the front end is driven to rotate at the same time, and when the spline rod (56) rotates, the rotating rod (57) at the front end of the hollow rod (51) is driven to rotate at the same time, and when the hollow rod (51) moves forward, it drives the rotating rod (57) connected to the inside to move forward at the same time, and the rotating rod (57) moves forward on the surface of the spline rod (56), and when the rotating rod (57) rotates, it drives the circulation chute (58) opened on the surface to rotate at the same time, and when the circulation chute (58) rotates, it drives the arc brush (55) slidably connected thereto to swing left and right along the routes of different angles on both sides of the circulation chute (58), which is different from the state in which the hollow rod (51) drives the arc brush (55) to extend horizontally for cleaning, and at the same time, the diameter of the arc brush (55) changes during the swinging, so as to better fit the inner wall of the heat collecting tube; S4, when the pinion (48) rotates in the reverse direction, the threaded rod (52) is driven to rotate in the reverse direction, and at the same time, the hollow rod (51) is driven to move backward horizontally and move outward from the inside of the heat collecting tube, and at the same time, the arc-shaped brush (55) on the surface is driven to pull out the scale and other debris cleaned from the inside of the heat collecting tube. At the same time, when the hollow rod (51) moves backward, it drives the rotating rod (57) connected to the inside to move backward at the same time. The rotating rod (57) moves backward on the surface of the spline rod (56). When the rotating rod (57) rotates, it drives the circulation chute (58) provided on the surface to rotate in the reverse direction at the same time. When the circulation chute (58) rotates, it drives the arc-shaped brush (55) slidably connected thereto to swing left and right in the reverse direction along the routes of different angles on both sides of the circulation chute (58), so as to better remove the scale and other debris from the inside of the heat collecting tube. At the same time, when the pinion (48) rotates forward and reverse, it drives the hollow rod (51) to form a back-and-forth reciprocating motion, so that continuous cleaning can be performed; S5. At the same time, when the screw (33) rotates, the meshing large gear (34) is driven to rotate. When the large gear (34) rotates, the eccentric wheels (35) on both sides are driven to rotate. The rotation of the eccentric wheels (35) drives the connecting rod (36) connected to the side to push or pull the Y-shaped clamping rod (39) to move forward and backward on the upper end of the cleaning seat (1). When the Y-shaped clamping rod (39) moves forward and backward, the annular groove (38) moves forward and backward. When the annular groove (38) moves forward and backward, the sleeve rod (37) moves forward and backward on the surface of the connecting rod (310). When the sleeve rod (37) moves, it drives the fixedly connected piston rod (45) to reciprocate forward and backward inside the piston storage barrel (46), injecting the acidic liquid inside the piston storage barrel (46) into the telescopic hose (49), and then passing through the liquid outlet (410) inside the heat collecting tube to decompose and remove the scale. After the acidic liquid in the piston storage barrel (46) is used up, it is added through the liquid injection port (47), and when the hollow rod (51) moves, the liquid outlet (410) is driven to move forward and backward through the telescopic hose (49).
