Description

Technical Field

[0001] The utility model relates to the technical field of embedded component waterproof structures, in particular to a waterproof structure of a pre-embedded steel casing for a thermal pipeline passing through an outer wall. Background Art

[0002] Thermal pipes are pipeline structures used to transport heat sources. Therefore, they need to be laid through walls so that the pipes can be laid indoors to provide heat sources for the room and also to discharge the indoor heat sources. To ensure the stability of the wall, pre-buried pipes need to be buried in the wall, and then the pipes need to be passed through the pre-buried pipes, which can reduce damage to the wall.

[0003] Today's embedded pipes are basically simple steel pipe structures. When water seepage occurs, water will flow between the pipes and the embedded pipes and finally flow onto the wall. There is no good guiding and protective structure. For this reason, a waterproof structure of thermal pipes passing through embedded steel casings in the exterior wall is proposed. Utility Model Content

[0004] The technical solution adopted by the utility model to solve the technical problem is: a waterproof structure of a pre-buried steel casing for a thermal pipeline passing through an outer wall, comprising a pre-buried pipe, an inner ring is arranged in the middle of the pre-buried pipe, a through hole is opened through the middle of the inner ring, a collecting groove is opened inside the inner ring, and the collecting groove is a semicircular structure, an outer ring is opened in the pre-buried pipe and close to the inner ring, an outer layer connecting port is opened through between the outer ring and the collecting groove and close to the top, and an inner layer connecting port is evenly opened through the side wall between the collecting groove and the through hole.

[0005] As a preferred technical solution of the utility model, the outer layer connecting port and the inner layer connecting port are both conical structures and face oppositely. The outer ring is filled with absorbent cotton. The opening edge of the outer layer connecting port near one end of the collecting tank is rotatably connected to an anti-backflow plate through a torsion spring, and the torsion spring is a unidirectional rotating structure.

[0006] As a preferred technical solution of the utility model, a water outlet is opened in the bottom of the embedded pipe near one end, and a drainage net is embedded in the opening of the bottom of the water outlet, and the collecting tank and one end of the outer ring are connected to the water outlet.

[0007] As a preferred technical solution of the utility model, a water collecting box is set at one end of the embedded pipe and below the drainage net. The water collecting box is an arc-shaped structure corresponding to the outer circle wall of the embedded pipe. The top opening of the water collecting box corresponds to the drainage net. A guide pipe is fixedly connected in the middle of the bottom side wall of the water collecting box.

[0008] As a preferred technical solution of the utility model, the bottom end of the water collecting tank is a conical structure, and the water collecting tank is detachably connected to the bottom side wall of the embedded pipe by screws. The guide pipe is fixedly connected to the side wall opposite to the embedded pipe by two connecting pipes, and the connecting pipe is an inclined structure. The end of the connecting pipe away from the water collecting tank is inserted into the embedded pipe and connected to the outer circle.

[0009] The utility model has the following advantages: the pipeline is inserted into the insertion hole, and when water seepage occurs, the water will flow into the collecting tank through the inner connecting port, and will not flow to the wall along the gap between the pipeline and the insertion hole, thereby improving the waterproof performance and reducing the risk of water seeping into the wall. As the water in the collecting tank increases, it will flow along the inner wall of the collecting tank and finally be discharged into the water collecting box through the water outlet and finally be discharged from the guide pipe without contacting the wall during the whole process. Because there is water in the collecting tank, water seeping into the outer circle during the alternation of cold and hot will be absorbed and locked by the absorbent cotton. As the water volume increases, the overflowing water will also flow into the water collecting box from the water outlet and finally be discharged by the guide pipe. The above can effectively increase the waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1-4The utility model discloses a waterproof structure of a pre-buried steel casing for a thermal pipeline passing through an outer wall, comprising a pre-buried pipe 1, an inner ring 7 is arranged in the middle of the pre-buried pipe 1, an insertion hole 10 is opened through the middle of the inner ring 7, a collecting groove 8 is opened inside the inner ring 7, and the collecting groove 8 is a semicircular structure. An outer ring 5 is opened in the pre-buried pipe 1 and close to the inner ring 7, an outer layer connecting port 9 is opened through between the outer ring 5 and the collecting groove 8 and close to the top, and an inner layer connecting port 11 is opened evenly through the side wall between the collecting groove 8 and the insertion hole 10.

[0017] The technical effect of this solution is as follows: the embedded pipe 1 is placed at a designated position, and then embedded in the wall by pouring, and the thermal pipe is inserted into the insertion hole 10. When water seepage occurs, it will flow into the collecting tank 8 from the inner connecting port 11, and will not flow from the gap between the pipeline and the insertion hole 10 to the wall to cause damage to the wall. The water entering the collecting tank 8 will flow through the water outlet into the water collecting tank 3 as it flows, and finally be discharged through the guide pipe 4, thereby avoiding the accumulation of water in the embedded pipe 1 and causing negative impact on the embedded pipe 1 itself.

[0018] The outer layer connecting port 9 and the inner layer connecting port 11 are both of conical structure and face in opposite directions. The outer ring 5 is filled with absorbent cotton 6. The edge of the opening of the outer layer connecting port 9 near one end of the collecting tank 8 is connected to the anti-backflow plate 13 through a torsion spring, and the torsion spring is a one-way rotating structure. A water outlet is opened in the bottom of the embedded pipe 1 near one end, and a drainage net 2 is embedded in the opening of the bottom of the water outlet. The collecting tank 8 and one end of the outer ring 5 are connected to the water outlet. A water collecting tank 3 is set at one end of the embedded pipe 1 and below the drainage net 2. The water collecting box 3 is an arc-shaped structure corresponding to the wall of the outer circle 5 of the embedded pipe 1. The top opening of the water collecting box 3 corresponds to the drainage net 2. A guide pipe 4 is fixedly connected to the middle of the bottom side wall of the water collecting box 3. The bottom end of the water collecting box 3 is a conical structure. The water collecting box 3 is detachably connected to the bottom side wall of the embedded pipe 1 by screws. The guide pipe 4 is fixedly connected to the side wall opposite to the embedded pipe 1 with two connecting pipes 12. The connecting pipe 12 is an inclined structure. The end of the connecting pipe 12 away from the water collecting box 3 is inserted into the embedded pipe 1 and is connected to the outer circle 5.

[0019] The technical effect of this solution is as follows: the absorbent cotton 6 can absorb and lock the water that seeps out through the alternating cold and hot conditions to prevent it from spreading outward. When the water is excessively absorbed, the overflowed water will flow back into the collection tank 8 through the outer layer connecting port 9, or enter the water outlet and be discharged through the water collecting box 3 and the guide pipe 4. Because the absorbent cotton 6 is absorbent, the transfer of water inside it is also relatively slow. For this reason, a connecting pipe 12 is set to connect the guide pipe 4 with a section of the outer ring 5 to achieve the function of guiding the discharge in advance and improve the overall efficiency.

[0020] Specifically, when the utility model is used, the embedded pipe 1 is embedded in the wall, and then the pipeline is inserted into the insertion hole 10. The seeped water passes through the inner layer connecting port 11 into the collecting tank 8 and flows in the collecting tank 8, and finally enters the water collecting box 3 and is discharged by the guide pipe 4, avoiding the traditional water flowing into the wall along the insertion hole 10 to damage the wall. The absorbent cotton 6 filled in the early outer ring 5 can absorb and lock the water that penetrates into the outer ring 5 due to the alternation of hot and cold. Continuous absorption of water will exceed the capacity of the absorbent cotton 6, and the space in the outer ring 5 is limited and the absorbent cotton 6 cannot expand, so pressure will be generated. Under pressure, the water is squeezed out and the water at a high place will return to the collecting tank 8 through the outer layer connecting port 9, while the water below will flow and finally be discharged through the water collecting box 3 and the guide pipe 4 like the water in the collecting tank 8, thereby improving the waterproof performance, reducing the probability of water seeping into the wall, and improving the safety of the wall.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0022] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
