Description

Technical Field

[0001] The invention relates to a ventilation structure, in particular to an energy-saving ventilation structure applied to the field of building ventilation. Background Art

[0002] Ventilation is a building environment control technology that uses ventilation dilution or ventilation removal to control the spread and harm of air pollutants and ensure the quality of indoor and outdoor air environments. The ventilation system is a complete set of devices that realize the ventilation function, including air inlets, exhaust vents, air supply ducts, fans, cooling and heating, filters, control systems and other ancillary equipment. When the ventilation ducts connecting indoor and outdoor are installed through the wall, the subsequent blocking of the wall is involved. In the existing technology, flexible fireproof materials are generally used for blocking, but it is easy to have insufficient contact between the blocking materials and the pipes and the inner walls of the wall holes, resulting in poor blocking effect.

[0003] In order to solve the problem of poor sealing effect mentioned above, the specification of Chinese invention patent CN201922331046.2 discloses a "fireproof ventilation duct structure", which is provided with hemp filling at the connection between the ventilation duct and the wall, and the two ends of the hemp filling are sealed by a cement mortar layer. A cover plate is attached to the side of the cement mortar layer located outdoors, one end of the cover plate extends to the wall and the other end extends to the ventilation duct. The cover plate is fixed to the ventilation duct by screws, and silicone is provided on the top of the screws, so that the openings on both sides of the wall hole have a good sealing effect without leaving gaps.

[0004] However, the strength and density of hemp fiber are not great, and the diameter of ventilation ducts is usually large, so the inner diameter of the matching wall hole is larger, and the low-strength hemp fiber cannot meet the strength effect of sealing the wall hole.

[0005] Application Contents

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is the poor sealing effect between the ventilation duct and the wall hole.

[0007] To solve the above problems, the present invention provides an energy-saving ventilation structure, including multiple ventilation pipes and a through-hole pipe section connected between two adjacent ventilation pipes, wherein the end of one of the most edge ventilation pipes is fixedly connected to a steering pipe, the lower end of the steering pipe is fixedly connected to an air outlet plate, the air outlet plate is installed on the indoor ceiling, and the end of the other most edge ventilation pipe is communicated with the outside world, the through-hole pipe section includes a middle through-hole pipe, side pipes located on the left and right sides of the middle through-hole pipe, and a buffer layer fixedly connected between the left and right ends of an adaptive layer and the side pipes, the outer end of the middle through-hole pipe is wrapped with an adaptive layer, a guide ring is arranged on the outer sleeve of the buffer layer, the outer end of the guide ring is fixedly connected to an input pipe, a plurality of shunt pipes are fixedly connected between the left and right ends of the adaptive layer and the adjacent guide rings, and the input pipe, the guide ring, the shunt pipe and the adaptive layer are communicated in sequence.

[0008] In the above energy-saving ventilation structure, by setting the through-hole pipe joint, when sealing the gap between the ventilation duct and the wall hole, cement slurry can be directly passed into the adaptive layer to make it expand and gradually fit the inner wall of the wall hole, which can effectively ensure the strength after sealing and effectively ensure that the gap between the through-hole pipe joint and the inner wall of the wall hole is fully sealed, and it is not easy to have gaps, so that the sealing effect is better.

[0009] As a further improvement of the present application, the buffer layer is made of elastic sealing material, so that the entire ventilation structure has a certain elasticity and lateral scalability, so that it has a certain buffering effect during ventilation and protects the pipeline from being easily damaged. The cross-section of the buffer layer is a concave structure, so that the guide rings and diverter pipes on it do not protrude from the surface of the through-hole pipe section, and are not easily affected by its installation.

[0010] As a further improvement of the present application, a plurality of evenly distributed pull rings are fixedly connected to the outer end of the middle part of the buffer layer, and the end of the pull ring away from the axis of the buffer layer does not exceed the side pipe. When the ventilation pipe is installed or other situations where buffering is not required, the plurality of pull rings can be pulled outward in sequence, and a plurality of rods can be used to penetrate the pull rings respectively, so that the rods are installed between the side pipes and the middle through-hole pipe. The plurality of rods can limit the buffer layer and effectively maintain the stability of the through-hole pipe section structure.

[0011] As a further improvement of the present application, the adaptive layer includes two positioning layers respectively fixed to the left and right ends of the middle through-hole pipe and a self-adhesive layer fixedly connected between the two positioning layers. The self-adhesive layer is an elastic sealing structure, and the connection point between the diversion pipe and the adaptive layer is located on the positioning layer. When sealing the gap between the through-hole pipe section and the wall hole, the adaptive layer can be directly inflated through the input pipe for pre-expansion treatment, and then cement slurry is introduced into the interior thereof, which continuously squeezes the self-adhesive layer, causing it to swell toward the inner wall of the wall hole and gradually adhere to the inner wall of the wall hole, so that the cement slurry is filled more fully and the wall hole sealing effect is better.

[0012] As another improvement of the present application, a plurality of evenly distributed side bonding strips are fixedly connected to the outer end of the self-bonding layer, two conductive wires extend from one end of each side bonding strip, and the conductive wires on the plurality of side bonding strips are located on the same side.

[0013] As another improved supplement to the present application, the measuring bonding strip includes an outer protective flexible strip and a plurality of measuring bonding balls connected in series with each other inside the outer protective flexible strip. The ends of the two wires located inside the measuring bonding strip are electrically connected to the measuring bonding balls on the left and right edge positions respectively. Half of the measuring bonding strip is located on the inner side of the self-bonding layer, and the other half of the measuring bonding strip protrudes out of the self-bonding layer. Before filling the cement slurry, ventilation is first performed to make the measuring bonding strip squeeze and contact with the inner wall of the wall, thereby making the plurality of measuring bonding balls conductive to each other. At this time, the measuring bonding strip is connected to a circuit with a small light bulb or an ammeter or a voltmeter to ensure that there is no problem inside the measuring bonding strip and that the circuit can be conductive.

[0014] As another improved supplement to the present application, two T-shaped contact pieces are connected to the measuring bonding ball, and the two T-shaped contact pieces do not contact each other. The measuring bonding ball includes an inner fixed hemisphere and an outer variable hemisphere that are fixed to each other and assembled into a complete spherical shape, and the connection between the two corresponds to the connection between the measuring bonding strip and the self-bonding layer. The two T-shaped contact pieces are respectively connected to the inner walls of the inner fixed hemisphere and the outer variable hemisphere that are close to each other. Since the two T-shaped contact pieces do not contact each other, although multiple measuring bonding balls are connected in series, the circuit cannot be turned on. Only when the two T-shaped contact pieces are in contact with each other can the two adjacent measuring bonding balls be turned on. When power is turned on, the current can pass smoothly, so that the light bulb on the circuit is lit, or the pointer of the circuit meter or voltmeter rotates.

[0015] As another improvement supplement to the present application, the inner hemisphere is located in the self-bonding layer, and the inner hemisphere is a hard structure, so that when the outer bonding strip has not yet contacted the inner wall of the wall hole, the inner hemisphere is not easily affected by gas or cement slurry and deformed prematurely, so that the two T-shaped contacts are not easily turned on prematurely. The outer hemisphere is located outside the self-bonding layer, and the outer hemisphere is an elastic sealing material, and the outer bonding ball is filled with insulating gas.

[0016] An energy-saving ventilation structure, a method for installing the ventilation structure through a wall comprises the following steps:

[0017] S1. First, pass the through-hole pipe section through the hole pre-cut on the wall, so that the two ends of the through-hole pipe section are located on both sides of the wall respectively;

[0018] S2. Inflate the adaptive layer through the input tube to make the adaptive layer swell, then connect the measuring strip in series to a circuit with a small bulb or an ammeter through two wires, and release the air when the circuit is turned on. The circuit turning on indicates that the measuring strip is normal;

[0019] S3, then fill the inside with cement slurry. When the amount of cement slurry introduced is large, the test strip is again connected in series to a circuit with a small bulb or an ammeter. When the circuit is detected to be conductive, it means that the entire test strip is in close contact with the inner wall of the wall hole. Finally, the openings on both sides of the wall hole are repaired and leveled with concrete, and the same putty as the wall is applied to complete the sealing of the wall hole.

[0020] S4. Finally, fix the end of the ventilation pipe and the through-hole pipe section by bolts, and at the same time, fix the ventilation pipe and the steering pipe by bolts in turn to complete the installation.

[0021] In summary, through the setting of the through-hole pipe joint, when sealing the gap between the ventilation duct and the wall hole, cement slurry can be directly passed into the adaptive layer to make it expand and gradually fit the inner wall of the wall hole, which can effectively ensure the strength after sealing, and at the same time effectively ensure that the gap between the through-hole pipe joint and the inner wall of the wall hole is fully sealed, and it is not easy to have gaps, so that the sealing effect is better. In addition, with the setting of the measuring fitting strip, in the process of filling cement slurry, it can be judged whether the expanded adaptive layer is in full contact with the inner wall of the wall according to whether the measuring fitting strip can make the circuit conductive. Compared with the existing technology, it can effectively improve the density of the gap sealing between the inner wall of the wall hole and the ventilation duct, so that the sealing effect is further improved.

DETAILED DESCRIPTION

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1-2 An energy-saving ventilation structure is shown, comprising a plurality of ventilation pipes 2 and a through-hole pipe section 1 connected between two adjacent ventilation pipes 2, wherein the end of one of the outermost ventilation pipes 2 is fixedly connected to a steering pipe 31, the lower end of the steering pipe 31 is fixedly connected to an air outlet plate 32, the air outlet plate 32 is installed on the indoor ceiling, and the end of the other outermost ventilation pipe 2 is communicated with the outside.

[0037] like Figure 3-4 The through-hole pipe section 1 includes a middle through-hole pipe 12, side pipes 11 located on the left and right sides of the middle through-hole pipe 12, and a buffer layer 13 fixedly connected between the left and right ends of the adaptive layer 4 and the side pipes 11. The buffer layer 13 is made of elastic sealing material, so that the entire ventilation structure has a certain elasticity and lateral scalability, so that it has a certain buffering effect during ventilation and air exchange, and protects the pipeline from being easily damaged. The cross-section of the buffer layer 13 is a concave structure, so that the guide ring 5 and the shunt pipe 6 on it can not protrude from the surface of the through-hole pipe section 1, and it is not easy to affect its installation; the outer end of the middle through-hole pipe 12 is wrapped with the adaptive layer 4, and the guide ring 5 is arranged on the outer sleeve of the buffer layer 13. The outer end of the guide ring 5 is fixedly connected with an input pipe 501, and a plurality of shunt pipes 6 are fixedly connected between the left and right ends of the adaptive layer 4 and the adjacent guide rings 5. The input pipe 501, the guide ring 5, the shunt pipe 6 and the adaptive layer 4 are sequentially connected.

[0038] like Figure 5 A plurality of evenly distributed pull rings 8 are fixedly connected to the outer end of the middle part of the buffer layer 13, and the end of the pull ring 8 away from the axis of the buffer layer 13 does not exceed the side tube 11. When the ventilation pipe 2 is installed or other situations where buffering is not required, the plurality of pull rings 8 can be pulled outward in sequence, and a plurality of rods can be used to penetrate the pull rings 8 respectively, so that the rods are erected between the side tube 11 and the middle through-hole tube 12. The plurality of rods can limit the buffer layer 13 and effectively maintain the stability of the through-hole pipe section 1 structure.

[0039] The adaptive layer 4 includes two positioning layers 42 respectively fixed to the left and right ends of the middle hole tube 12 and a self-adhesive layer 41 fixedly connected between the two positioning layers 42. The self-adhesive layer 41 is an elastic sealing structure, and the connection point between the shunt tube 6 and the adaptive layer 4 is located on the positioning layer 42. Figure 6 When sealing the gap between the through-hole pipe section 1 and the wall hole, the adaptive layer 4 can be directly inflated through the input pipe 501 to perform a pre-expansion treatment, and then cement slurry is introduced into the adaptive layer 4, which continuously squeezes the self-adhesive layer 41, causing it to swell toward the inner wall of the wall hole and gradually adhere to the inner wall of the wall hole, so that the cement slurry is filled more fully and the wall hole sealing effect is better.

[0040] The second implementation method:

[0041] Figure 7 As shown, a plurality of evenly distributed side bonding strips 7 are fixedly connected to the outer end of the self-bonding layer 41, two wires 73 extend from one end of each side bonding strip 7, and the wires 73 on the plurality of side bonding strips 7 are all located on the same side.

[0042] like Figure 8 The measuring bonding strip 7 includes an outer protective flexible strip 71 and a plurality of measuring bonding balls 72 connected in series with each other in the outer protective flexible strip 71. The ends of the two wires 73 located in the measuring bonding strip 7 are electrically connected to the measuring bonding balls 72 at the left and right edge positions respectively. One half of the measuring bonding strip 7 is located on the inner side of the self-bonding layer 41, and the other half of the measuring bonding strip 7 protrudes out of the self-bonding layer 41. Before filling the cement slurry, ventilation is first performed to make the measuring bonding strip 7 squeeze and contact with the inner wall of the wall, thereby making the plurality of measuring bonding balls 72 conductive to each other. At this time, the measuring bonding strip 7 is connected to a circuit with a small light bulb or an ammeter or a voltmeter to ensure that there is no problem in the measuring bonding strip 7 and the circuit can be conductive.

[0043] See also Fig. 9 , two T-shaped contact pieces 723 are connected to the side fitting ball 72, and the two T-shaped contact pieces 723 do not contact each other. The side fitting ball 72 includes an inner fixed hemisphere 721 and an outer variable hemisphere 722 fixed to each other and assembled into a complete spherical shape, and the connection between the two corresponds to the connection between the side fitting strip 7 and the self-fitting layer 41. The two T-shaped contact pieces 723 are respectively connected to the inner walls of the inner fixed hemisphere 721 and the outer variable hemisphere 722 close to each other. Since the two T-shaped contact pieces 723 do not contact each other, as shown in FIG. Figure 9-10 Therefore, although multiple measuring balls 72 are connected in series, the circuit cannot be conducted. Only when two T-shaped contact pieces 723 are in contact with each other, can the two adjacent measuring balls 72 be conducted. When power is turned on, the current can pass smoothly, the bulb on the circuit can be lit, or the pointer of the circuit meter or voltmeter can rotate.

[0044] The inner hemisphere 721 is located in the self-bonding layer 41, and the inner hemisphere 721 is a hard structure, so that when the side bonding strip 7 has not yet contacted the inner wall of the wall hole, the inner hemisphere 721 is not easily affected by gas or cement slurry and deformed in advance, so that the two T-shaped contact pieces 723 are not easily turned on in advance. The outer hemisphere 722 is located outside the self-bonding layer 41, and the outer hemisphere 722 is an elastic sealing material, and the side bonding ball 72 is filled with insulating gas.

[0045] It is worth noting that the T-shaped contact piece 723 connected to the hard inner fixed hemisphere 721 is longer than the other T-shaped contact piece 723. When it is squeezed by gas or cement slurry, it expands outward from the bonding layer 41. Only after the bonding strip 7 contacts the inner wall of the wall hole, the outer variable hemisphere 722 will deform, causing the T-shaped contact piece 723 to move closer to the longer T-shaped contact piece 723 until contact and conduction are achieved.

[0046] An energy-saving ventilation structure, a method for installing the ventilation structure through a wall comprises the following steps:

[0047] S1, first pass the through-hole pipe section 1 through the hole pre-cut on the wall, so that the two ends of the through-hole pipe section 1 are respectively located on both sides of the wall;

[0048] S2, inflate the adaptive layer 4 through the input tube 501 to make the adaptive layer 4 swell, then connect the measuring sticking strip 7 in series to a circuit with a small bulb or an ammeter through two wires 73, and release the air when the circuit is turned on. The circuit turning on indicates that the measuring sticking strip 7 is normal;

[0049] S3, then fill the inside with cement slurry. When the amount of cement slurry introduced is large, the measuring strip 7 is again connected in series to the circuit with a small bulb or an ammeter. When the circuit is detected to be conductive, it means that the measuring strip 7 as a whole is in close contact with the inner wall of the wall hole. Finally, the openings on both sides of the wall hole are repaired and leveled with concrete, and the same putty as the wall is applied to complete the sealing of the wall hole.

[0050] S4. Finally, the ventilation pipe 2 is fixed to the end of the through-hole pipe section 1 by bolts, and the ventilation pipe 2 is fixedly connected to the steering pipe 31 by bolts in sequence, and the installation is completed.

[0051] In summary, through the setting of the adaptive layer 4, when sealing the gap between the ventilation duct and the wall hole, cement slurry can be directly passed into the adaptive layer 4 to make it expand and gradually fit the inner wall of the wall hole, which can effectively ensure the strength after sealing, and at the same time effectively ensure that the gap between the through-hole pipe section 1 and the inner wall of the wall hole is fully sealed, and it is not easy to have gaps, so that the sealing effect is better. In addition, with the setting of the measuring fitting strip 7, in the process of filling cement slurry, it can be judged whether the expanded adaptive layer 4 is in full contact with the inner wall of the wall according to whether the measuring fitting strip 7 can make the circuit conductive. Compared with the existing technology, the density of the gap sealing between the inner wall of the wall hole and the ventilation duct can be effectively improved, so that the sealing effect is further improved.

[0052] In addition, optionally, the self-adhesive layer 41 can be set to a porous elastic structure, and a hot-melt layer can be wrapped around the self-adhesive layer 41 to seal the holes on the self-adhesive layer 41. When the ventilation structure is installed through the wall, after step S3, a step of heating the centering hole pipe 12 can be added to melt the hot-melt layer and leak out the pores of the self-adhesive layer 41. At this time, the cement slurry inside overflows and directly contacts the inner wall of the wall hole, so that the connection stability between the cement slurry and the wall hole is higher after solidification, and the sealing effect is better. During specific implementation, it can be selected whether to set it according to actual needs.

[0053] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
