Description

Technical Field

[0001] This utility model relates to the field of heating pipe cleaning technology, specifically a heating pipe cleaning device. Background Technology

[0002] Heating is one of the earliest building environment control technologies developed by humankind. It refers to supplying heat to buildings by heating water, which then flows and transports the heat to each household. Radiators then raise the indoor temperature, achieving the purpose of heating and maintaining a certain indoor temperature. It is a social service that addresses the basic heating needs of residents in northern my country during winter.

[0003] A search of the patent document CN 220772029 U on the China Patent Network reveals a heat pipe cleaning device that uses a high-pressure spray nozzle assembly to clean the inside of the heat pipe, avoiding direct friction between the cleaning mechanism and the inner wall of the heat pipe, reducing wear on the device and lowering maintenance costs.

[0004] However, the above technical solution has certain shortcomings. It only uses high-pressure nozzles to tilt the inner wall of the pipe. As hot water flows in the pipe for a long time, impurities and scale in the water settle and adhere to the inner wall of the pipe in the radiator. The high-pressure nozzles cannot thoroughly clean the scale adhering to the inner wall, which may even affect the subsequent heating effect. Therefore, a heating pipe cleaning device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a heating pipe cleaning device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a heating pipe cleaning device, including a water tray frame, wherein the curved outer wall of the water tray frame is equipped with multiple sets of positioning components that slide on the inner wall of the pipe, and the rear end of the water tray frame is connected to a cleaning component for rinsing the inner wall of the pipe.

[0007] The cleaning component includes a diversion plate connected to the rear end of the water tray frame. The curved outer wall of the diversion plate is connected to four sets of drain pipes in a ring array. The outer wall of the four sets of drain pipes is fixedly fitted with positioning rings. The outer wall of each set of drain pipes is connected to an arc-shaped nozzle. The arc-shaped nozzle is located at the end of the drain pipe away from the diversion plate. The curved outer wall of the positioning ring is fixed with two sets of dividing blades. One side of each set of dividing blades is fixed with a scraper on the outer wall of the positioning ring.

[0008] As a preferred technical solution, the front end of the diversion plate is provided with a receiving pipe that is connected to the water tray frame, and the receiving pipe is rotatably configured with the diversion plate.

[0009] As a preferred technical solution, a water supply pipe is connected to the front end of the water tray frame. The water supply pipe is connected to an external water pipe via a flange. Multiple pull rings are provided on the outer side of the water supply pipe at the front end of the water tray frame.

[0010] As a preferred technical solution, the positioning component includes an outer cylinder fixed to the outer wall of the curved surface of the water tray frame, an inner rod extending to the outer side of the outer cylinder end face is slidably provided inside the outer cylinder, a return spring fixed to the end face of the inner rod is provided inside the outer cylinder, and a constraint wheel set that contacts the inner wall of the pipe is assembled at the end of the inner rod.

[0011] As a preferred technical solution, the dividing blade is arc-shaped and is fixed to the outer wall of the positioning ring in an inclined state.

[0012] As a preferred technical solution, the end section of the shovel bar is trapezoidal, and multiple sets of notches are equally spaced on the inclined surface of the shovel bar.

[0013] As a preferred technical solution, the inner diameter of the arc-shaped nozzle is smaller than that of the drain pipe, and the drain pipe and the diverter plate are concentric.

[0014] In summary, the present invention has the following main advantages:

[0015] This invention uses water pressure to make the cleaning component rotate inside the pipe, allowing the water source to fully contact the curved inner wall of the pipe, thus improving the cleaning quality of the heating pipe. At the same time, the rotation of the cleaning component causes the cutting blade to cut the scale on the inner wall of the pipe, thereby weakening the connection between the fruit and the inner wall of the pipe. The scale can then be cleaned by the action of the scraper, making the cleaning of the scale attached to the inner wall of the pipe more efficient and convenient. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A heating pipe cleaning device, such as Figures 1 to 5 As shown, it includes a water tray frame 100, the curved outer wall of the water tray frame 100 is equipped with multiple sets of positioning components 110 that slide on the inner wall of the pipe, and the rear end of the water tray frame 100 is connected to a cleaning component for rinsing the inner wall of the pipe.

[0026] The cleaning assembly includes a diversion plate 150 connected to the rear end of the water tray frame 100. The curved outer wall of the diversion plate 150 is connected to four sets of drain pipes 160 in a ring array. The outer wall of the four sets of drain pipes 160 is fixedly sleeved with a positioning ring 130. The outer wall of each set of drain pipes 160 is connected to an arc-shaped nozzle 170. The arc-shaped nozzle 170 is located at the end of the drain pipe 160 away from the diversion plate 150. The curved outer wall of the positioning ring 130 is fixed with two sets of dividing blades 190. On one side of each set of dividing blades 190, a scraper 180 is fixed on the outer wall of the positioning ring 130.

[0027] The front end of the diversion plate 150 is provided with a receiving pipe 151 that is connected to the water tray frame 100. The receiving pipe 151 and the diversion plate 150 are rotatably configured.

[0028] The end section of the shovel 180 is trapezoidal, and multiple sets of notches 181 are equally spaced on the inclined surface of the shovel 180.

[0029] The device needs to be inserted from one end of the heating pipe, and the external high-pressure water pipe is connected to the water tray frame 100. A pull rope is used to connect the device to the pull ring 140. Pulling the pull rope can make the device move inside the pipe. The water source enters the diversion plate 150 through the water tray frame 100 and flows into the four sets of drain pipes 160. Finally, it is discharged from the arc-shaped nozzle 170. The discharged water contacts the inner wall of the pipe and generates a reverse thrust on the drain pipe 160. This can cause the diversion plate 150 and the drain pipe 160 on the outer wall to rotate around the axis of the receiving pipe 151, so that the drained water source fully contacts the inner wall of the pipe and achieves a better cleaning purpose.

[0030] As the diverter plate 150 rotates, its positioning ring 130 also rotates synchronously. The dividing blade 190 will contact and cut the hard objects (scale) on the inner wall of the pipe, reducing the connection force between the divided hard objects and the inner wall of the pipe. Then, the scraper 180 will contact the divided hard objects, making it easier to scrape them off the inner wall of the pipe. As the device moves inside the pipe, it will finally clean the pipe.

[0031] Please refer to this carefully. Figure 1 , Figure 2 and Figure 5 The front end of the water tray frame 100 is connected to a water supply pipe 101, which is connected to an external water pipe via a flange. Multiple pull rings 140 are provided on the outer side of the water supply pipe 101 at the front end of the water tray frame 100.

[0032] The positioning component 110 includes an outer cylinder 112 fixed to the curved outer wall of the water tray frame 100, an inner rod 111 extending to the outer side of the end face of the outer cylinder 112 is slidably provided inside the outer cylinder 112, a return spring 113 fixed to the end face of the inner rod 111 is provided inside the outer cylinder 112, and a constraint wheel set 120 that contacts the inner wall of the pipe is assembled at the end of the inner rod 111.

[0033] The external pull rope can be tied to the pull ring 140, and a pulling force can be applied to make the device move inside the pipe. When the positioning part 110 comes into contact with the scale on the inner wall of the pipe, the inner rod 111 can retract into the outer cylinder 112 to compress the return spring 113, so that the device can pass over the surface of the scale, making it move smoothly inside the pipe and achieve a high degree of scale cleaning effect.

[0034] The external water pipe is bolted to the end face of the water supply pipe 101. It can deliver water through the water tray frame 100 and the distribution plate 150, and finally spray it onto the inner wall of the pipe to complete the cleaning purpose.

[0035] Please refer to this carefully. Figure 3 The dividing blade 190 is arc-shaped and is fixed to the outer wall of the positioning ring 130 in an inclined state.

[0036] As the positioning ring 130 rotates, the curved surface (cutting surface) of the dividing blade 190 gradually comes into contact with the scale on the inner wall of the pipe until the purpose of dividing is completed.

[0037] Please refer to this carefully. Figure 3 The inner diameter of the arc-shaped nozzle 170 is smaller than that of the drain pipe 160, and the drain pipe 160 and the diverter plate 150 are concentric.

[0038] This makes the water pressure inside the drain pipe 160 greater than the water pressure inside the arc-shaped nozzle 170, which can make the water discharged from the arc-shaped nozzle 170 have sufficient pressure, thereby generating a reverse thrust on the drain pipe 160 and the arc-shaped nozzle 170, causing the diverter plate 150 to rotate.

[0039] When in use, the device needs to be inserted into one end of the heating pipe, and the external high-pressure water pipe is connected to the water tray frame 100. A pull rope is used to connect the device to the pull ring 140. Pulling the pull rope can make the device move inside the pipe. The water source enters the diversion plate 150 through the water tray frame 100 and flows into the four sets of drain pipes 160. Finally, it is discharged from the arc-shaped nozzle 170. The discharged water contacts the inner wall of the pipe and generates a reverse thrust on the drain pipe 160, which can make the diversion plate 150 and the drain pipe 160 on the outer wall rotate around the axis of the receiving pipe 151, so that the drained water source fully contacts the inner wall of the pipe and achieves a better cleaning purpose.

[0040] As the diverter plate 150 rotates, its positioning ring 130 also rotates synchronously. The dividing blade 190 contacts and cuts the hard material (scale) on the inner wall of the pipe, reducing the connection force between the divided hard material and the inner wall of the pipe. Then, the scraper 180 contacts the divided hard material, making it easier to scrape it out from the inner wall of the pipe. As the device moves inside the pipe, it finally cleans the pipe. The parts of the device not mentioned are the same as or can be implemented using existing technology.

[0041] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.

After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
