Description

Technical Field

[0001] This utility model relates to the field of underground pipe dehumidification, and in particular to a condensate guiding structure for a dehumidification pipe. Background Technology

[0002] Drainage pipes are an important structural component of underground pipelines. Because moisture inevitably exists in the soil or insulation layer surrounding underground pipelines, the pipeline and insulation material undergo thermal expansion and contraction during operation and shutdown, causing changes in internal air pressure. The main function of the drainage pipe is to provide a safe and controllable outlet for this moisture that inevitably enters the insulation layer. However, moisture may condense into droplets at the outlet of the drainage pipe and flow back into the insulation layer. Current solutions involve installing check valves on the drainage pipes. While check valves prevent liquid water from flowing back into the insulation layer, the accumulated liquid water on the check valve requires regular cleaning, which is labor-intensive. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a condensate guiding structure for a desiccant pipe. A guide rod is set inside the desiccant pipe to guide the condensed droplets out of the desiccant pipe and reduce the backflow of droplets in the desiccant pipe.

[0004] Technical solution: To achieve the above objectives, this utility model provides a condensate guiding structure for a condensate drain pipe, comprising a condensate drain pipe with an elbow at the top and a downward-facing condensate drain outlet; a guide rod is installed inside the elbow, with a height difference between its two ends, the lower end of the guide rod extending towards the condensate drain outlet, and the higher end of the guide rod connected to several branches, which have several contact points with the inner wall of the elbow; condensate droplets formed on the inner wall of the elbow can flow along the branches to the guide rod, and then flow along the guide rod towards the condensate drain outlet.

[0005] Furthermore, the guide rod is installed inside the elbow via a movable frame. The branch is elastic, and the movable frame's displacement can cause the branch to elastically abut against the inner wall of the elbow.

[0006] Furthermore, the movable frame includes a slide and a connecting rod, and the guide rod is connected to the slide through the connecting rod; a sliding groove is provided on the inner wall of the elbow, and the slide can be movably inserted into the sliding groove; as the slide goes deeper into the sliding groove, the branches gradually approach and abut against the inner wall of the upper bend section.

[0007] Furthermore, the chute extends along the pipe body direction of the bend, and the chute is located near the vent. A pre-insertion port is provided at the end of the chute away from the vent. The slide block can be inserted into the pre-insertion port and slide into the chute from the pre-insertion port.

[0008] Furthermore, the elbow, the chute, and the guide rod are all arc-shaped; the distance between the chute and the center of the elbow gradually decreases as the slide seat moves deeper into the chute, and the branches gradually move away from the center of the elbow and elastically abut against the inner wall of the outer ring of the elbow.

[0009] Furthermore, a weight is connected to the lower end of the guide rod, and the gravity of the weight causes the slide to tend to move deeper into the groove.

[0010] Furthermore, a check valve is installed on the vent pipe.

[0011] Beneficial effects: The present invention provides a condensate guiding structure for a desiccant pipe, wherein a guide rod is provided inside the bend of the desiccant pipe. One end of the guide rod extends toward the desiccant outlet, and the other end of the guide rod is forked and connected to the inner wall of the bend. This allows the condensed droplets inside the bend to flow along the forks to the guide rod, and then along the guide rod toward the desiccant outlet, thereby reducing the backflow of droplets in the desiccant pipe.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] As attached Figures 1 to 3 The aforementioned condensate guiding structure for a condensate drain pipe includes a condensate drain pipe 1. The lower end of the condensate drain pipe 1 is inserted into the insulation layer 15 of the buried pipeline 14. The top of the condensate drain pipe 1 is connected to an elbow 2, which has a downward-facing condensate outlet 3. The elbow 2 at the upper end of the condensate drain pipe 1 prevents other foreign objects from entering the condensate drain pipe 1. The elbow 2 is divided into a lower bend section 5 near the condensate outlet 3 and an upper bend section 4 away from the condensate outlet 3. Moisture in the insulation layer 15 will be discharged upward along the condensate drain pipe 1. The moisture in the condensate drain pipe 1 will first enter the upper bend section 4, then enter the lower bend section 5, and finally be discharged from the condensate outlet 3.

[0015] Moisture near the drain outlet 3 may cool and condense into droplets. Due to the shape of the elbow 2, droplets condensed on the inner wall of the lower bend section 5 will still be discharged from the drain outlet 3, but droplets condensed on the inner wall of the upper bend section 4 will flow back into the drain pipe 1. Therefore, in the prior art, a check valve 13 is usually installed on the drain pipe 1 to prevent droplets from flowing back into the insulation layer 15. However, liquid water accumulation on the check valve 13 requires regular cleaning, which is labor-intensive. Therefore, it is necessary to reduce the backflow of droplets in the drain pipe 1, thereby reducing the frequency of cleaning the water accumulation on the check valve 13.

[0016] In this invention, a guide rod 6 is installed inside the elbow 2. The guide rod 6 has a height difference between its two ends. The lower end of the guide rod 6 extends towards the drain outlet 3, and the higher end of the guide rod 6 is connected to several branches 7. These branches 7 have several contact points with the inner wall of the upper bend section 4. Thus, droplets condensing on the inner wall of the upper bend section 4 can flow from the contact points to the branches 7, then along the branches 7 to the guide rod 6, and finally along the guide rod 6 to the drain outlet 3. With the help of the guide rod 6 and the branches 7, the droplets condensing on the inner wall of the upper bend section 4 can be diverted. A portion of the droplets flows towards the drain outlet 3, while the remaining droplets flow back into the drain pipe 1 and are blocked by the check valve 13. However, the amount of droplets flowing back into the drain pipe 1 is reduced, thus reducing the frequency of cleaning the water accumulated on the check valve 13 and lowering manpower consumption.

[0017] A movable frame 8 is provided inside the elbow 2, and the guide rod 6 is connected to the movable frame 8, thereby fixing the position of the guide rod 6 inside the drainage pipe 1. The branch 7 is elastic, and the movable displacement of the movable frame 8 can cause the other end of the branch 7 to elastically abut against the inner wall of the upper bend section 4, thereby keeping the branch 7 in contact with the inner wall of the upper bend section 4.

[0018] Specifically, the movable frame 8 includes a slide 11 and a connecting rod 12, and the guide rod 6 is connected to the slide 11 through the connecting rod 12. A groove 10 is provided on the inner wall of the elbow 2, and the slide 11 is movably inserted into the groove 10. As the slide 11 moves deeper into the groove 10, the branch 7 gradually approaches and abuts against the inner wall of the upper bend section 4, keeping the branch 7 in contact with the inner wall of the upper bend section 4.

[0019] As attached Figure 2 and 3 As shown, the chute 10 extends along the pipe body direction of the elbow 2. The chute 10 is located near the vent 3. A pre-insertion port 16 is provided at the end of the chute 10 away from the vent 3. The slide block 11 can be inserted into the pre-insertion port 16 and slide into the chute 10 from the pre-insertion port 16. The end of the chute 10 near the vent 3 is sealed so that the slide block 11 will not fall out of the chute 10 after it is slid into it.

[0020] The lower end of the guide rod 6 is connected to a weight block 9. The gravity of the weight block 9 causes the slide block 11 to tend to move deeper into the slide groove 10. The weight block 9 itself is streamlined, making it less likely to obstruct the discharge of moisture.

[0021] The elbow 2, the chute 10, and the guide rod 6 are all arc-shaped. The distance between the chute 10 and the center of the elbow 2 gradually decreases towards the drain outlet 3. The guide rod 6 is also arc-shaped, with branches 7 obliquely connected to its higher end. As the slide block 11 extends deeper along the chute 10, it gradually approaches the center of the elbow 2. Since the slide block 11 and branches 7 are located at opposite ends of the guide rod 6, the branches 7 gradually move away from the center of the elbow 2, thus elastically abutting against the inner wall of the outer ring of the elbow 2.

[0022] The shape of the branches 7 can be varied. In one embodiment, the branches 7 are divided into at least two fan-shaped arrays. The contact points formed by the branches 7 within the same fan-shaped array are distributed in a fan shape on the inner wall of the upper bend section 4, while the contact points formed by the branches 7 within different fan-shaped arrays are interlaced on the inner wall of the upper bend section 4. Thus, when a droplet leaks between two branches 7 of one fan-shaped array, the droplet is more likely to flow onto the branch 7 in the next fan-shaped array, thereby improving the droplet capture capability of the branches 7.

[0023] In this invention, because a guide rod 6 is installed inside the elbow 2, the condensed droplets inside the elbow 2 can be guided to the drain outlet 3, thereby reducing the backflow of droplets in the drain pipe 1 and reducing the frequency of cleaning the liquid water on the check valve 13, thus reducing manpower consumption. The guide rod 6 is slidably installed in the groove 10 of the elbow 2 through the movable frame 8. This ensures that the branch 7 and the inner wall of the upper bend pipe section 4 remain in contact with each other. Furthermore, when cleaning the water accumulated on the check valve 13, the guide rod 6 needs to be removed, and the sliding installation method simplifies the operation required to remove and install the guide rod 6.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
