Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning equipment, and more specifically to an integrated machine for cleaning floating rust and collecting sand and dust on the inner wall of heating pipelines. Background Technology

[0002] Heating pipelines are pipes used in heating networks to transport heating media such as steam or hot water. Heating pipelines require welding during installation, and after installation, the rust and impurities inside the pipes need to be cleaned. Currently, there are various types of pipe cleaning equipment on the market, but their performance is relatively limited; most can only peel off dirt but cannot remove it from the pipes, and their application conditions are very limited.

[0003] Most existing pipe cleaning equipment on the market is not suitable for the complex construction conditions of heating pipe networks, such as high temperature environment, pressure fluctuation, pipe material characteristics and pipe diameter changes, resulting in poor cleaning effect on the inner wall of the pipe, which may seriously affect the stable operation of the entire heating system.

[0004] Strictly controlling the cleaning of the inner wall of the pipeline during construction solves the problem of cleaning the inner wall of the heating pipeline network. This can not only reduce the energy consumption of the system, extend the service life of equipment, and reduce maintenance costs, but also improve energy utilization efficiency, which is in line with the national energy conservation and emission reduction policy and has significant social and economic benefits.

[0005] Therefore, there is a need for an integrated machine that can clean the inner wall of heating pipes and collect sand and dust, suitable for cleaning urban heating pipes. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned shortcomings and provide an integrated machine for cleaning and collecting floating rust and sand dust from the inner wall of heating pipes.

[0007] Therefore, this utility model provides an integrated machine for cleaning floating rust and collecting sand and dust on the inner wall of heating pipes, including a walking frame. A walking component is installed at the bottom of the walking frame. The walking component is used to drive the walking frame to move back and forth. A cleaning component for cleaning the inner wall of the heating pipe is installed at the top of the walking frame. A dust collection component is provided on one side of the cleaning component to collect the impurities after cleaning by the cleaning component.

[0008] The cleaning assembly includes a drive motor, a transmission shaft mounted on the conveyor shaft of the drive motor, a snap-fit ​​block fixedly mounted on the outer surface of the transmission shaft, a bushing sleeve fitted onto the outer surface of the transmission shaft, a snap-fit ​​groove formed on the inner wall of the bushing, the snap-fit ​​groove snapping into the outer surface of the snap-fit ​​block, a connecting rod mounted on the outer surface of the bushing, a connecting assembly mounted on the top of the connecting rod, a cleaning brush mounted on the top of the connecting assembly, and the connecting assembly capable of driving the cleaning brush to extend and retract within the connecting rod for adjustment.

[0009] The dust collection assembly includes a collection sleeve, a conical filter screen is installed at one end of the inner wall of the collection sleeve, a planetary gear set is installed at the other end of the inner wall of the collection sleeve, a connecting shaft is installed on one side of the planetary gear set, and a fan blade is installed on the side of the connecting shaft away from the planetary gear set. The rotation of the fan blade can draw impurities into the collection sleeve.

[0010] As a further improvement to this technical solution, the connecting assembly includes a sliding groove formed at the top of the connecting rod, a telescopic rod slidably installed inside the sliding groove, a brush disc fixedly installed at the top of the telescopic rod, a compression spring sleeved on the outer surface of the telescopic rod, the top of the compression spring installed at the bottom of the brush disc, the bottom of the compression spring installed at the top of the connecting rod, and the brush disc fixedly installed at the bottom of the sweeping brush; the sweeping brush can be adjusted for extension and retraction by compressing the compression spring.

[0011] As a further improvement to this technical solution, four connecting rods and cleaning brushes are provided, and the four connecting rods and cleaning brushes are arranged in a circumferential array on the outer surface of the bushing, for cleaning the inner wall of the heating pipe.

[0012] As a further improvement to this technical solution, the end of the drive shaft away from the drive motor passes through the collection sleeve and extends into the interior of the planetary gear set, so that the rotation of the drive shaft can drive the cleaning brush and the planetary gear set to rotate together.

[0013] As a further improvement to this technical solution, two planetary gear sets are provided, and the two planetary gear sets are connected by a coupling, which can achieve two-stage acceleration of the connecting shaft.

[0014] As a further improvement to this technical solution, a camera module is installed on the top of the vehicle frame, which is used to monitor the environment inside the heating pipeline and the vehicle body.

[0015] As a further improvement to this technical solution, two walking frames are provided, and the two walking frames are respectively installed at the bottom of the cleaning component and the dust collection component.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] 1. In this integrated machine for cleaning floating rust and dust collection on the inner wall of heating pipes, the cleaning component and the dust collection component are integrated to clean the dirt out of the heating pipes in one go: the cleaning component scrapes off the impurities on the inner wall of the heating pipes, peeling the dirt inside the heating pipes from the inner wall of the pipes, and then the dust collection component sucks up the floating dust, particles and other dirt swept off by the cleaning brush and removes them from the inner wall of the pipes.

[0032] Most existing pipe cleaning equipment on the market is not suitable for the complex construction conditions of heating pipe networks, such as high temperature environment, pressure fluctuation, pipe material characteristics and pipe diameter changes, resulting in poor cleaning effect on the inner wall of the pipe, which may seriously affect the stable operation of the entire heating system.

[0033] like Figures 1-6 As shown, the device includes a traveling frame 1, a traveling component 2 is installed at the bottom of the traveling frame 1, the traveling component 2 is used to drive the traveling frame 1 to move back and forth, a cleaning component 3 for cleaning the inner wall of the heating pipe is installed at the top of the traveling frame 1, and a dust collection component 4 is provided on one side of the cleaning component 3 to collect the impurities after cleaning by the cleaning component 3.

[0034] The cleaning assembly 3 includes a drive motor 31, a transmission shaft 32 is mounted on the conveying shaft of the drive motor 31, a snap-fit ​​block 33 is fixedly mounted on the outer surface of the transmission shaft 32, a bushing 34 is sleeved on the outer surface of the transmission shaft 32, a snap-fit ​​groove 35 is opened on the inner wall of the bushing 34, the snap-fit ​​groove 35 snaps into the outer surface of the snap-fit ​​block 33, a connecting rod 36 is mounted on the outer surface of the bushing 34, a connecting assembly 37 is mounted on the top of the connecting rod 36, a cleaning brush 38 is mounted on the top of the connecting assembly 37, and the connecting assembly 37 can drive the cleaning brush 38 to extend and retract within the connecting rod 36 for adjustment;

[0035] The dust collection assembly 4 includes a collection sleeve 41. A conical filter screen 42 is installed on one end of the inner wall of the collection sleeve 41, and a planetary gear set 43 is installed on the inner wall of the other end of the collection sleeve 41. A connecting shaft 44 is installed on one side of the planetary gear set 43, and a fan blade 45 is installed on the side of the connecting shaft 44 away from the planetary gear set 43. The rotation of the fan blade 45 can draw impurities into the collection sleeve 41.

[0036] Furthermore, the traveling frame 1 is driven by the traveling assembly 2, enabling the traveling frame 1 to move forward and backward inside the heating pipe. The drive motor 31 mounted on the top of the traveling frame 1 can be connected to the bushing 34 through the transmission shaft 32. The bushing 34 is slidably fitted onto the transmission shaft 32, allowing the snap-fit ​​groove 35 on the inner wall of the bushing 34 to snap onto the outer surface of the snap-fit ​​block 33, limiting the bushing 34. A connecting rod 36 and a cleaning brush 38 (the cleaning brush 38 is a wire brush, which has a good cleaning effect, wear resistance, and will not damage the inner wall of the pipe during cleaning) are fixedly installed on the outer surface of the bushing 34. The drive motor 31 drives the transmission shaft 32 and the bushing 34 to rotate, causing the cleaning brush 38 to clean and scrape off the rust and impurities on the inner wall of the heating pipe. The dust collection assembly 4 located behind the cleaning assembly 3 can be rotated by the fan blades to suck the scraped impurities into the collection sleeve 41 for collection, achieving the effect of cleaning and collecting impurities on the inner wall of the heating pipe.

[0037] It should be noted that the walking assembly 2 consists of a walking motor, a drive shaft, a driving drive wheel, and a driven drive wheel. The walking motor drives the drive wheel to rotate via the drive shaft, thereby generating driving force. The forward and reverse rotation function of the walking motor enables the machine to move forward and backward. The drive wheel and driven wheel are made of steel core with rubber coating to ensure that they can withstand sufficient rotational force and friction, while the polyurethane adhesive layer has a certain shock absorption effect. This effectively addresses the potential obstruction to the normal movement of the machine caused by the weld seam inside the spiral welded pipe. The internal structural connections of the walking assembly 2 are existing technology, and its working principle is common knowledge to those skilled in the art, and will not be elaborated here.

[0038] First, considering the question of how the cleaning brush 38 can be pressed against the inner wall of the heating pipe for cleaning, the following is provided: Figure 1 and Figure 4 The specific structure of the connecting component 37 is disclosed. The connecting component 37 includes a sliding groove 301 formed on the top of the connecting rod 36. A telescopic rod 302 is slidably installed inside the sliding groove 301. A brush disc 303 is fixedly installed on the top of the telescopic rod 302. A compression spring 304 is sleeved on the outer surface of the telescopic rod 302. The top of the compression spring 304 is installed on the bottom of the brush disc 303. The bottom of the compression spring 304 is installed on the top of the connecting rod 36. The brush disc 303 is fixedly installed on the bottom of the sweeping brush 38. The sweeping brush 38 can adjust its extension and retraction by compressing the compression spring 304.

[0039] There are four connecting rods 36 and cleaning brushes 38. The four connecting rods 36 and cleaning brushes 38 are arranged in a circumferential array on the outer surface of the bushing 34 for cleaning the inner wall of the heating pipe.

[0040] Furthermore, by creating a sliding groove 301 at the top of the connecting rod 36, the telescopic rod 302 can be limited and installed inside the sliding groove 301 for sliding. A brush plate 303 is installed on the top of the telescopic rod 302 to install the cleaning brush 38. A compression spring 304 is sleeved on the outer surface of the telescopic rod 302. When the integrated machine enters the heating pipe, the operator presses the cleaning brush 38, which presses the compression spring 304 downward. The telescopic rod 302 drives the cleaning brush 38 to retract into the connecting rod 36, making the circumferential diameter of the cleaning brush 38 smaller than that of the heating pipe. After the cleaning brush 38 can enter the heating pipe, the operator releases the cleaning brush 38, and the compression spring 304 returns to its original position, so that the cleaning brush 38 presses against the inner wall of the heating pipe to clean the impurities on the inner wall of the heating pipe.

[0041] Secondly, considering how the dust collection component 4 collects the swept-down impurities, [the following is presented] Figure 3 The end of the drive shaft 32 away from the drive motor 31 passes through the collection sleeve 41 and extends into the interior of the planetary gear set 43, so that the rotation of the drive shaft 32 can drive the cleaning brush 38 to rotate together with the planetary gear set 43.

[0042] There are two planetary gear sets 43, which are connected by a coupling to achieve two-stage acceleration of the connecting shaft 44.

[0043] Furthermore, the first planetary gear set 43 is connected to the drive shaft 32, which drives the sun gear on the inner wall of the planetary gear set 43 to rotate at an accelerated speed. The first planetary gear set 43 is connected to the second planetary gear set 43 through a coupling, which again drives the sun gear in the second planetary gear set 43 to rotate at an accelerated speed. This allows the connecting shaft 44 connected to the second planetary gear set 43 to drive the fan blades 45 to rotate at an accelerated speed, causing the airflow to accelerate and creating a pressure difference. This allows the impurities scraped off by the cleaning brush 38 to be sucked into the collection sleeve 41 for collection. The impurities are intercepted and collected by the conical filter screen 42 inside the collection sleeve 41, while the air flows out normally, achieving the effect of collecting the scraped impurities.

[0044] Secondly, considering the question of how the integrated unit works inside the heating pipes, [the following is provided]: Figures 1-6 A camera module 5 is installed on the top of the walking frame 1. The camera module 5 is used to monitor the environment inside the heating pipeline and the vehicle body.

[0045] Furthermore, camera module 5 can monitor the all-in-one machine, monitoring the cleanliness of the inner wall, observing welding defects on the inner wall of the pipe, and monitoring the machine's own balance. It mainly consists of a PTZ camera, a Cat5e network cable, a small monitoring camera, a field fiber optic cable, a photoelectric converter transmitter, a photoelectric converter receiver, a monitoring hard disk recorder, a portable hard drive, and a monitor. Camera module 5 is divided into two parts: one part is the PTZ camera at the front of the machine, connected via a Cat5e network cable, transmitting the signal through the conductive slip ring on the brush plate 303 shaft to the rear of the machine. The photoelectric converter then converts the electrical signal into an optical signal, which is transmitted to the monitor via the field fiber optic cable, and the hard disk recorder automatically records the video. The other part is a small camera mounted on the machine's support frame, which observes the level on the frame in real time and converts the electrical signal into an optical signal via the photoelectric converter, transmitting it to the monitor via the field fiber optic cable. When operating the machine outside the pipe, it is necessary to observe the machine's balance in real time and make adjustments as needed. The use of field optical cables effectively avoids the problem of electrical signals being shielded by the inner wall of steel pipes. The internal structure and wiring connections of the above-mentioned device are existing technologies, and their working principle is common knowledge to those skilled in the art, so they will not be described in detail here.

[0046] Finally, considering the issue of how the walking frame 1 moves while the cleaning brush 38 rotates and contacts the inner wall of the heating pipe, the following is presented: Figure 6 There are two walking frames 1, which are respectively installed at the bottom of the cleaning assembly 3 and the dust collection assembly 4.

[0047] Furthermore, the walking frame 1 is divided into two parts, which are respectively installed at the bottom of the cleaning brush assembly 3 and the dust collection assembly 4. The walking motor installed on the top of the walking frame 1 at the bottom of the cleaning brush assembly 3 can drive the wheels at the bottom of the walking frame 1 to rotate through gears. The drive motor 31 is connected to the planetary gear set 43 through the transmission shaft 32, so that the walking frame 1 under the cleaning brush assembly 3 can move and drive the walking frame 1 at the bottom of the dust collection assembly 4 to move together, so that the rotation of the cleaning brush 38 is not affected when the device is moved and pushed.

[0048] It should be noted that during operation, the traveling frame 1 moves while cleaning the inner wall of the pipe, and the resulting friction can cause the traveling frame 1 to tilt. Therefore, a level and a monitoring camera are installed on the frame to monitor the degree of tilt and prevent the machine from tipping over inside the pipe. Furthermore, to adjust the machine's balance, a crank is installed at the driven wheel axle, with a small-power motor connected to one end of the crank. The forward and reverse rotation of the motor controls the trajectory of the driven wheel to adjust the machine's balance. The internal structure and wiring connections of the above device are existing technology, and their working principle is common knowledge to those skilled in the art, and will not be elaborated upon here.

[0049] In summary, the working principle of this solution is as follows:

[0050] The camera module 5, together with the walking component 2 and the walking frame 1, enables the all-in-one machine to move smoothly inside the heating pipe, allowing the drive motor 31 to drive the bushing 34 on the transmission shaft 32 to rotate, thereby enabling the four cleaning brushes 38 installed on the outer surface of the bushing 34 to clean the inner wall of the heating pipe, achieving the effect of cleaning the inner wall of the heating pipe.

[0051] A collection sleeve 41 is installed on one side of the cleaning component 3, so that the drive shaft 32 can be connected to the planetary gear set 43 inside the collection sleeve 41. The two sets of planetary gear sets 43 accelerate the rotation of the fan blades 45 on the connecting shaft 44, which can suck the cleaned impurities into the inside of the collection sleeve 41. The conical filter screen 42 inside the collection sleeve 41 can intercept and gather the impurities for unified treatment.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
