Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drainage technology, specifically relating to an air conditioning condensate drainage system. Background Technology
[0002] In cities, air conditioner condensate is typically discharged directly into the underground municipal sewer system via condensate pipes. However, in the Middle East, Africa, and underdeveloped rural areas, where underground condensate pipes and other drainage facilities are lacking, residents often carelessly extend the condensate pipes after installing air conditioners. The condensate flows directly onto the ground, causing unsightly damage, obstructing pedestrian traffic, and even leading to slips and falls. Furthermore, the condensate is often discharged into untreated raw soil layers rather than hardened layers like reinforced concrete or brick. Over time, this erosion can cause soil loss and leave deep pits, damaging the soil structure, leading to foundation settlement, and posing safety hazards to buildings. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an air conditioning condensate drainage system that improves the stability of soil structure and enhances the safety of buildings.
[0004] The technical solution adopted by this utility model to solve the technical problem is: an air conditioning condensate drainage system, including a foundation pit and a condensate pipe for draining air conditioning condensate. The bottom wall of the foundation pit is laid with a base platform, and a seepage pipe is vertically arranged above the base platform. The lower end face of the seepage pipe is in contact with the upper end face of the base platform, and the upper end face of the seepage pipe is above the ground surface.
[0005] The seepage pipes are arranged at intervals with the sidewalls of the foundation pit to form an annular space. The annular space is filled with seepage filler to form a seepage support strip, and the top surface of the seepage support strip is flush with the ground surface. The drain outlet at the lower end of the condensate pipe is located inside the seepage pipe, and the seepage pipe is filled with seepage filler to form a seepage buffer strip.
[0006] The seepage pipe has multiple seepage holes on its sidewall, and these multiple seepage holes are located below the ground surface; the annular space is connected to the cavity of the seepage pipe through the seepage holes.
[0007] Furthermore, the upper end of the seepage pipe protrudes upwards from the ground surface.
[0008] Furthermore, the drainage pipe is a PVC pipe.
[0009] Furthermore, the diameter of the seepage holes is less than 5 mm; and the plurality of seepage holes are evenly distributed along the circumference of the seepage pipe.
[0010] Furthermore, multiple seepage holes are distributed in the lower part of the seepage pipe.
[0011] Furthermore, geotextile is laid on the sidewall of the foundation pit outside the seepage support strip.
[0012] Furthermore, the drain outlets at the lower end of the condensate pipe are spaced above the seepage buffer zone.
[0013] Furthermore, the top surface of the seepage buffer strip is spaced below the upper end face of the seepage pipe.
[0014] Furthermore, the permeable filler in both the permeable support strip and the permeable buffer strip is crushed stone; the particle size of the crushed stone in the permeable support strip is smaller than that in the permeable buffer strip.
[0015] Furthermore, it also includes a dust cover, which includes a cover plate with a mounting through hole at the center and a downwardly protruding annular flange on the outer edge of the cover plate;
[0016] The lower end of the condensate pipe passes through the mounting hole of the cover plate and is inserted into the seepage pipe. The cover plate covers the upper end of the seepage pipe and seals the upper port of the seepage pipe. The annular flange is sleeved on the outside of the seepage pipe and fits against the outer wall of the seepage pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: It provides an air conditioning condensate drainage system. By setting a base platform and a seepage pipe with seepage holes in the foundation pit to form a drainage buffer space, the condensate first enters the drainage buffer space and then seeps out through the seepage holes on the seepage pipe. This avoids the condensate in the condensate pipe directly eroding the soil, causing soil erosion and damaging the soil structure, thus improving the stability of the soil structure and the safety of surrounding buildings. By setting a seepage buffer strip in the seepage pipe to buffer the condensate discharged from the condensate pipe, the potential energy of the water flow is reduced, allowing it to slowly seep out through the seepage holes. This also avoids the condensate directly impacting the seepage pipe and its bottom base platform, thus preventing damage. By setting a seepage support strip to support the side wall of the foundation pit and horizontally positioning the seepage pipe on the base platform, the stability of the soil on the side wall of the foundation pit is improved. At the same time, the water flowing out through the seepage holes is further buffered before seeping into the soil on the side of the foundation pit, further reducing the impact force of water flow on the soil around the foundation pit and improving the structural stability of the soil outside the foundation pit. In addition, the seepage support strip is also used to isolate the seepage pipe from the foundation pit, preventing soil from falling off the side wall of the foundation pit and blocking the seepage holes on the seepage pipe.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. 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.
[0023] As attached Figure 1-3 As shown, an air conditioning condensate drainage system includes a pit 1 and a condensate pipe 9 for draining air conditioning condensate. A base 2 is laid on the bottom wall of the pit 1, and a seepage pipe 3 is vertically installed above the base 2. The lower end face of the seepage pipe 3 is in contact with the upper end face of the base 2, and the upper end face of the seepage pipe 3 is above the ground surface. The seepage pipe 3 and the side wall of the pit 1 are arranged at intervals to form an annular space. A seepage support band 4 is formed within the annular space by a seepage filler, and the top surface of the seepage support band 4 is flush with the ground surface. The drain outlet at the lower end of the condensate pipe 9 is located inside the seepage pipe 3, which is filled with a seepage filler to form a seepage buffer band 5. Multiple seepage holes 31 are provided on the side wall of the seepage pipe 3, and these holes are located below the ground surface. The annular space and the cavity of the seepage pipe 3 are connected through the seepage holes 31.
[0024] Both the permeable support strip 4 and the permeable buffer strip 5, formed by permeable filler, have a loose structure and uniformly distributed pores. The condensate generated by the air conditioner flows into the cavity of the permeable pipe 3 through the condensate pipe 9. After the water flow impacts the permeable buffer strip 5, it seeps down through the pores of the permeable buffer strip 5 to the permeable hole 31 and then seeps out through the permeable hole 31 into the annular space. The water in the annular space slowly seeps outward through the pores of the permeable support strip 4 into the lower soil on the side of the foundation pit.
[0025] This invention creates a drainage buffer space by setting up a base platform 2 and a seepage pipe 3 with seepage holes 31 inside the foundation pit 1. This allows condensate to first enter the drainage buffer space and then seep out through the seepage holes 31 on the seepage pipe 3, preventing condensate in the condensate pipe 9 from directly eroding the soil and causing soil erosion and damage to the soil structure, thus improving the stability of the soil structure and the safety of surrounding buildings. By setting a seepage buffer strip 5 inside the seepage pipe 3 to buffer the condensate discharged from the condensate pipe 9, the potential energy of the water flow is reduced, allowing it to slowly seep out through the seepage holes 31, and also preventing condensate from directly impacting the seepage pipe 3 and its bottom base platform 2 and causing damage. By setting a seepage support strip 4 to support the side wall of the foundation pit 1 and horizontally positioning the seepage pipe 3 on the base platform 2, the stability of the soil on the side wall of the foundation pit 1 is improved, and the water flowing out through the seepage holes 31 is further buffered before seeping into the soil on the side of the foundation pit 1, further reducing the impact force of water flow on the soil around the foundation pit 1 and improving the structural stability of the soil on the outside of the foundation pit 1. In addition, the seepage support strip 4 is also used to isolate the seepage pipe 3 from the foundation pit 1, preventing soil from falling off the side wall of the foundation pit 1 and blocking the seepage holes 31 on the seepage pipe 3. Crops can be planted around the foundation pit 1, and the condensate can be used to irrigate the surrounding crops after seeping out through the drainage system of this utility model. This not only improves the stability of the soil structure, but also reuses the condensate, saving resources and being environmentally friendly.
[0026] The foundation pit 1 is used to bury and fix the base platform 2, the seepage pipe 3, the seepage support strip 4, and the seepage buffer strip 5. The cross-section of the foundation pit 1 can be of any shape, such as rectangular, circular, hexagonal, or any other structure. The base platform 2 is a reinforced concrete structure used to harden the bottom wall of the foundation pit 1, improve the stability of the bottom wall of the foundation pit 1, and prevent condensate from directly seeping into the bottom soil layer of the foundation pit 1, which would cause the seepage pipe 3, the seepage support strip 4, and the seepage buffer strip 5 to sink.
[0027] The seepage pipe 3 and the base 2 form a water storage space with an open top. Combined with the seepage buffer zone 5 inside, it buffers the condensate discharged from the condensate pipe 9, allowing the water to seep out through the seepage hole 31. The upper end of the seepage pipe 3 can be flush with the ground surface or protrude upwards. Preferably, the upper end of the seepage pipe 3 protrudes upwards to prevent surface soil from shifting into the seepage pipe 3 under external forces and blocking the gaps in the seepage buffer zone 5 and the seepage hole 31, thus affecting the smoothness of water infiltration.
[0028] The seepage pipe 3 can be a pipe structure with a circular, square, or other cross-sectional shape, and can be made of steel, concrete, plastic, or other materials. Preferably, the seepage pipe 3 is a PVC pipe, which is lightweight, easy to process, and convenient for construction. Generally, the diameter of the seepage pipe 3 is 150mm-200mm, and the length is 30cm-50cm, to prevent water seepage from affecting the hardness of the upper soil layer and to improve the stability of the surface soil structure.
[0029] The seepage hole 31 can be any shape, such as a round hole or a square hole. Generally, the seepage hole 31 is a round hole. To ensure a slow seepage effect, the diameter of the seepage hole 31 is generally less than 5 mm. Multiple seepage holes 31 can be evenly arranged on one side of the seepage pipe 3, or symmetrically arranged on both sides of the seepage pipe 3. Preferably, the multiple seepage holes 31 are evenly distributed along the circumference of the seepage pipe 3, and the water in the seepage pipe 3 seeps out evenly along the circumference of the seepage pipe 5.
[0030] The seepage holes 31 can be evenly distributed along the axial direction of the seepage pipe 3, or they can be set only in the upper, middle, or lower part of the seepage pipe 3. As a further preferred embodiment, multiple seepage holes 31 are distributed in the lower part of the seepage pipe 3. Generally, the uppermost seepage hole 31 is more than 10cm away from the ground surface to ensure that the water in the seepage pipe 3 seeps out from the lower part of the seepage pipe 3, avoiding the upper soil from being soaked by the seeping water, ensuring the stability of the surface soil structure, and ensuring safety and aesthetics.
[0031] The seepage support strip 4 is used to support the sidewall of the foundation pit 1 and fix the seepage pipe 3 inside the foundation pit 1. It isolates the sidewall of the foundation pit 1 from the seepage pipe 3, buffering the water flow from the seepage hole 31 and allowing the water to slowly seep into the surrounding soil of the foundation pit 1. It also prevents the water flowing from the seepage hole 31 from directly impacting the sidewall of the foundation pit 1, causing soil disturbance and falling to block the seepage hole 31, thus ensuring the stability of the sidewall of the foundation pit 1 and the unobstructed seepage channel. Preferably, geotextile 6 is laid on the sidewall of the foundation pit 1 outside the seepage support strip 4 to prevent sand, gravel, and soil clods from falling into the pores of the seepage support strip 4 and blocking the seepage channel, further ensuring the stability of the soil structure of the sidewall of the foundation pit 1.
[0032] The seepage buffer strip 5 is used to buffer the condensate discharged from the condensate pipe 9. The lower end of the condensate pipe 9 can extend into the seepage buffer strip 5 or be spaced above it. Preferably, the drain outlets at the lower end of the condensate pipe 9 are spaced above the seepage buffer strip 5 to prevent the filler in the seepage buffer strip 5 from blocking the drain outlets of the condensate pipe 9 and to ensure smooth drainage of the air conditioner. The lower end of the condensate pipe 9 is generally spaced 2-3 cm from the seepage buffer strip 5.
[0033] The upper surface of the seepage buffer strip 5 can be flush with the top surface of the seepage pipe 3, or it can be arranged at intervals below the upper surface of the seepage pipe 3. Considering that the condensate pipe 9 and the seepage buffer strip 5 are arranged at intervals, in order to prevent the water discharged from the condensate pipe 9 from splashing out of the seepage pipe 3 after being buffered by the seepage buffer strip 5, preferably, the top surface of the seepage buffer strip 5 is arranged at intervals below the upper surface of the seepage pipe 3.
[0034] The permeable filler in the permeable support strip 4 and the permeable buffer strip 5 can be crushed stone, gravel, sand, or mixtures thereof. Preferably, the permeable filler in the permeable support strip 4 and the permeable buffer strip 5 is crushed stone. Compared to gravel, sand, and other fillers, crushed stone is more robust and has a larger particle size, making it less likely to be washed away by water flow, and providing better buffering and permeability. The crushed stone in the permeable support strip 4 and the permeable buffer strip 5 can be the same type or different types. Because the water flow just discharged from the condensate pipe 9 has a large potential energy, the gaps in the permeable buffer strip 5 used to buffer the water flow from the condensate pipe 9 should be large enough and robust enough. Therefore, the permeable buffer strip 5 can use crushed stone with a larger particle size. The permeable pipe 3 is generally filled with crushed stone with a particle size of 20-30mm. As a further preferred option, the particle size of the crushed stone in the permeable support strip 4 is smaller than that in the permeable buffer strip 5. Using smaller particle size crushed stone in the permeable support strip 4 is more conducive to the uniform distribution of condensate into the soil around the perimeter of the foundation pit 1. To ensure that the seepage path is long enough, the single-sided gap between the side wall of the foundation pit 1 and the annular space of the seepage pipe 3 should be more than 10cm.
[0035] The condensate drain pipe 9 is used to drain the condensate from the air conditioner into the drain pipe 3. The condensate drain pipe 9 can be a rigid straight pipe arranged from top to bottom, or it can be a flexible bend. If the condensate drain pipe 9 is a flexible bend, the filler inside the drain pipe 3 can easily deform it, hindering drainage. Specifically, the condensate drain pipe 9 includes a horizontal pipe section 91 spaced above the drain pipe 3 and a vertical pipe section 92 extending downwards into the drain pipe 3. Both the horizontal pipe section 91 and the vertical pipe section 92 are rigid straight pipe structures, and they can be connected by a bend joint to ensure smooth drainage of the condensate into the drain pipe 3. The axis of the horizontal pipe section 91 is parallel to the horizontal plane, and the vertical pipe section 92 is located below the horizontal pipe section 91 and perpendicular to it.
[0036] In some areas with abundant sand and dust, sand and dust are easily carried into the seepage pipe 3 by the wind. Preferably, the system also includes a dust cover 7, which comprises a cover plate 71 with a central mounting hole and a downward-protruding annular flange 72 on its outer edge. The lower end of the condensate pipe 9 passes through the mounting hole of the cover plate 71 and is inserted into the seepage pipe 3. The cover plate 71 covers the upper end of the seepage pipe 3, sealing its upper port. The annular flange 72 is fitted onto the outside of the seepage pipe 3 and fits snugly against its outer wall. The outer wall of the condensate pipe 9 fits tightly against the wall of the mounting hole on the cover plate 71 without any gaps. The cover plate 71 ensures the condensate pipe 9 is inserted into the seepage pipe 3 while simultaneously sealing its upper port, preventing sand and dust from entering and blocking the seepage holes. The annular flange 72 is used to radially fix the entire dust cover 7 onto the seepage pipe 3.
[0037] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
