Description

Technical Field

[0001] This utility model relates to the field of thermal insulation drainage pipe devices, and in particular to a drainage pipe device for cold regions with thermal insulation function. Background Technology

[0002] In cold regions, the insulation of drainage pipes has always been a key challenge in engineering design and maintenance. Due to the low temperature, the water in the pipes is prone to freezing, which can lead to blockages or even ruptures. This not only affects the normal operation of the drainage system but may also trigger a series of chain problems, such as damage to building structures and equipment failures. Therefore, insulating drainage pipes in cold regions is not only a necessary technical measure but also an important means of ensuring the safety of life and production and protecting the environment. Utility Model Content

[0003] To overcome the drawback of water freezing in pipes, causing blockages or even ruptures and affecting the normal operation of drainage systems, this utility model provides a drainage pipe device with heat preservation function for cold regions.

[0004] The technical solution is as follows: A drainage pipe device for cold regions with heat preservation function, comprising a drainage pipe body, a rotating mechanism, a sealing baffle, a heating pipe, and an air outlet pipe; a heating pipe is fixedly connected to the drainage pipe body; several air outlet pipes are connected to the heating pipe; at least three air transmission channel structures are equidistantly opened on the drainage pipe body; the outlet end of the air outlet pipe is connected to the corresponding air transmission channel structure; a sealing baffle for blocking the outlet end of the air outlet pipe is slidably connected within each air transmission channel structure; a rotating mechanism is connected inside the drainage pipe body to drive the sealing baffle to rotate within the air transmission channel structure; the rotating mechanism connects all the sealing baffles.

[0005] Furthermore, the rotating mechanism includes a rotating ring, a motor, a drive bevel gear, and a bevel rack; at least two rotating rings are rotatably connected inside the drain pipe body; all sealing baffles are fixedly connected to the rotating rings; a motor is installed on the drain pipe body; the output shaft of the motor is fixedly connected to the drive bevel gear; a bevel rack is fixedly connected to any one of the rotating rings, and the bevel rack meshes with the drive bevel gear.

[0006] Furthermore, the sealing baffle and the corresponding area of ​​the air outlet pipe are provided with microporous structures.

[0007] Furthermore, an insulation sleeve to enhance the heat insulation effect is fixed to the outer surface of the drainage pipe.

[0008] Furthermore, a rotating frame is rotatably connected to the heating pipe; all sealing baffles are fixed to the rotating frame; a scraper is fixed to the rotating frame, and the scraper is in close contact with the surface of the heating pipe.

[0009] Furthermore, the scraper blade has a toothed structure on the side near the heating pipe.

[0010] Furthermore, a temperature sensor is installed inside the drain pipe to monitor the temperature of the discharged water flow.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a drainage pipe device with heat preservation function for cold regions. A heating pipe is installed inside the drainage pipe. The warm air flowing in the heating pipe, together with the insulation sleeve outside the drainage pipe, can directly heat and insulate the discharged water, preventing freezing. The drainage pipe also has multiple air-transmitting channels. When the temperature drops sharply to varying degrees, a rotating mechanism controls the sealing degree of the sealing baffles on the air-transmitting channels, thereby controlling the flow rate of warm air from the heating pipe to the air-transmitting channels. This achieves simultaneous heating of the water discharged from the drainage pipe from both the inside and outside, while minimizing heating consumption. Furthermore, the rotating mechanism can also drive a scraper to remove ice from the surface of the heating pipe, ensuring normal water flow.

[0012] By using a drainage pipe device with heat preservation function for cold regions, this invention overcomes the technical problem that water in the pipe is prone to freezing, leading to pipe blockage or even rupture, which affects the normal operation of the drainage system.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] This embodiment provides a drainage pipe device for cold regions with heat insulation function, such as... Figures 1-4As shown, it includes a drain pipe body 1, a rotating mechanism, a sealing baffle 15, a heating pipe 2, and an air outlet pipe 21; the heating pipe 2 is fixedly connected inside the drain pipe body 1, and the heating pipe 2 is connected to a heating transmission device; several air outlet pipes 21 are connected to the heating pipe 2; three air transmission channel structures 101 are equally spaced on the drain pipe body 1; the outlet end of each air outlet pipe 21 is connected to the corresponding air transmission channel structure 101; a sealing baffle 15 for blocking the outlet end of the air outlet pipe 21 is slidably connected inside each of the three air transmission channel structures 101; a rotating mechanism is connected inside the drain pipe body 1; the rotating mechanism is connected to all the sealing baffles 15.

[0021] like Figure 3 As shown, in this embodiment, the rotating mechanism includes a rotating ring 11, a motor 12, a drive bevel gear 13, and a bevel rack 14; two rotating rings 11 are rotatably connected inside the drain pipe body 1; all rotating rings 11 are fixedly connected to all sealing baffles 15; a motor 12 is installed on the drain pipe body 1; the output shaft of the motor 12 is fixedly connected to the drive bevel gear 13; a bevel rack 14 is fixedly connected to any rotating ring 11, and the bevel rack 14 meshes with the drive bevel gear 13; when the motor 12 drives the drive bevel gear 13 to rotate, the drive bevel gear 13 meshes with the bevel rack 14 to drive the rotating ring 11 to rotate, and at the same time the rotating ring 11 drives the sealing baffles 15 to rotate in the air supply channel structure 101; micropore structures 1501 are opened in the areas corresponding to the three sealing baffles 15 and the air outlet pipe 21, and the micropore structures 1501 are not initially aligned with the corresponding air outlet pipe 21.

[0022] like Figure 3 As shown, in this embodiment, a temperature sensor 5 is installed inside the drain pipe 1. When the temperature sensor 5 detects that the temperature of the discharged water flowing inside the drain pipe 1 is lower than the specified value, the temperature sensor 5 sends a working command to the motor 12, which is connected to the external heating equipment and the rotating mechanism, through the circuit system. The rotating mechanism drives the sealing baffle 15 to leave the air outlet pipe 21 to perform the corresponding heat preservation work.

[0023] In this embodiment, a drainage pipe device with heat preservation function for cold regions is installed on the drainage system. The discharged water flows inside the drainage pipe body 1. When the temperature sensor 5 detects that the temperature of the discharged water has dropped to near the freezing point, the temperature sensor 5 sends a first-level heat preservation command to the external heating supply equipment through the circuit system. The external heating supply equipment continuously supplies heat to the heating pipe 2. The heat in the heating pipe 2 directly heats the discharged water flowing inside the drainage pipe body 1. At the same time, the heat preservation sleeve 3 installed on the outside of the drainage pipe body 1 can reduce the heat loss from the heating. While minimizing the consumption of heating, it can efficiently preserve the discharged water.

[0024] Based on the first-level insulation work, when the temperature sensor 5 detects that the temperature of the discharged water flow has dropped to near freezing point, the temperature sensor 5 sends a second-level insulation work command to the external heating delivery equipment and motor 12 through the circuit system. The external heating delivery equipment increases the flow rate of heating air continuously delivered to the heating pipe 2. At the same time, the motor 12 drives the drive bevel gear 13 to drive the rotating ring 11 connected to the bevel rack 14 to rotate until the rotating ring 11 drives the sealing baffle 15 to rotate until the microporous structure 1501 is connected to the corresponding air outlet pipe 21. At this time, part of the heating air flowing through the heating pipe 2 will flow along the air outlet pipe 21 through the microporous structure 1501 to the corresponding air delivery channel structure 101. The heating air flowing through each air delivery channel structure 101 surrounds the outside of the discharged water flow flowing in the drain pipe body 1. Together with the heating air flowing in the heating pipe 2, it heats the outside and inside of the discharged water flow, enhancing the insulation effect of the discharged water flow.

[0025] Based on the secondary insulation work, when the temperature sensor 5 detects that the temperature of the discharged water flow has dropped to near freezing point, the temperature sensor 5 sends a tertiary insulation work command to the external heating delivery equipment and motor 12 through the circuit system. The external heating delivery equipment increases the flow rate of heating air continuously delivered to the heating pipe 2. At the same time, the motor 12 drives the bevel gear 13 to rotate the rotating ring 11 connected to the bevel rack 14 until the rotating ring 11 drives the sealing baffle 15 to completely leave the corresponding air outlet pipe 21. At this time, part of the heating air flowing through the heating pipe 2 will flow directly along the air outlet pipe 21 into the corresponding air delivery channel structure 101, allowing more heating air to flow in the air delivery channel structure 101, further enhancing the insulation effect of the discharged water flow.

[0026] like Figure 3 and Figure 4 As shown, in this embodiment, an insulation sleeve 3 for enhanced heat insulation is fixed to the outer surface of the drain pipe body 1; a rotating frame 41 is rotatably connected to the heating pipe 2; all sealing baffles 15 are fixed to the rotating frame 41; three scraper strips 42 are fixed to the rotating frame 41, and the scraper strips 42 are in close contact with the surface of the heating pipe 2; the three scraper strips 42 are provided with a toothed groove structure on the side near the heating pipe 2.

[0027] Based on the three-stage insulation work, the motor 12 periodically reciprocates to drive the bevel gear 13 to drive the rotating ring 11 connected to the bevel rack 14 to rotate, so that the rotating ring 11 drives the sealing baffle 15 to rotate back and forth. The reciprocating rotating sealing baffle 15 drives the scraper 42 on the rotating frame 41 to rotate back and forth synchronously in close contact with the surface of the heating pipe 2. This allows the scraper 42 to scrape off the ice slag that condenses on the surface of the heating pipe 2 in the cold environment. The scraped ice slag will be flushed away by the drain water in time, preventing more and more ice slag from condensing on the surface of the heating pipe 2 and affecting the normal flow of the drain water.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
