Description

Technical Field

[0001] This invention relates to an underground utility tunnel ventilation system, and more particularly to a high-efficiency underground integrated utility tunnel ventilation device with air convection function. Background Technology

[0002] Underground utility tunnels refer to public tunnels located underground in cities used for the centralized laying of municipal pipelines such as electricity, communications, broadcasting and television, water supply, and heating. The construction of urban underground utility tunnels not only solves problems such as "road zipper" issues, "overhead spider web" ductwork, and frequent pipeline accidents, but also plays a vital role in ensuring urban safety, improving urban functions, enhancing the city's appearance, and promoting economic growth. Underground locations naturally require ventilation equipment to exchange air and reduce unpleasant phenomena such as mold, dampness, and odors. Currently, most utility tunnels use ordinary supply and exhaust ventilation systems.

[0003] Existing underground utility tunnel ventilation systems have the following drawbacks in use:

[0004] 1. Most ventilation devices can only exhaust air inside underground utility tunnels, but cannot introduce fresh air from the outside into the tunnels, resulting in poor actual ventilation efficiency.

[0005] 2. During the ventilation process, filters are installed in the ventilation device to avoid dust and other debris. After long-term use, the air pores of the filter are easily clogged, and the filter plate needs to be replaced regularly, which is inconvenient. Summary of the Invention

[0006] The purpose of this invention is to provide a high-efficiency ventilation and air exchange device for underground integrated pipe corridors with air convection function, which has a good air diversion and air guiding effect to achieve the purpose of ventilation and air exchange.

[0007] This invention is implemented as follows:

[0008] A high-efficiency underground utility tunnel ventilation and air exchange device with air convection function includes a main body, a coupling-driven exhaust mechanism, a prefabricated dust filter mechanism, a coupling-driven air guiding mechanism, and a multi-port ventilation mechanism. The prefabricated dust filter mechanism is installed inside the main body and includes an outer air inlet trough and an inner air outlet trough. The outer air inlet trough is located on one side of the inner part of the main body, and the inner air outlet trough has several corners forming a Z-shaped structure. One end of the inner air outlet trough is located in the upper part of the outer air inlet trough, and the other end of the inner air outlet trough penetrates the side wall of the outer air inlet trough and extends to the main body. The internal side of the device body; the coupling drive exhaust mechanism is located on the internal side of the device body, and the coupling drive exhaust mechanism includes several exhaust fans, which are correspondingly located at several corners in the exhaust inner trough frame; the coupling air guiding mechanism is located at the side end of the device body, and the coupling air guiding mechanism includes driven air guiding fans, which are located in the lower part of the air inlet outer trough frame; one end of the two multi-port ventilation mechanisms is respectively connected to the device body at intervals and communicates with the air inlet outer trough frame and the exhaust inner trough frame, and the other end of the two multi-port ventilation mechanisms is connected to multiple underground integrated pipe gallery rooms.

[0009] The exhaust duct is equipped with a flow guide, which is inclinedly positioned at the corner of the exhaust duct.

[0010] The aforementioned coupling-driven exhaust mechanism includes a coupling maintenance chamber, an assembly base plate, a directional drive shaft frame, a first drive belt, a driven drive shaft frame, a second drive belt, a first motor, a drive shaft, a first exhaust fan, and a second exhaust fan. The coupling maintenance chamber is located inside the main body of the device on the other side, between several corners of the exhaust duct frame. The assembly base plate is located at the bottom of the coupling maintenance chamber, and the directional drive shaft frame and the driven drive shaft frame are respectively and spaced apart on the assembly base plate. The first drive belt drives between the directional drive shaft frame and the driven drive shaft frame, and one end of the second drive belt drives between the directional drive shaft. On the frame, an insert rod is rotatably installed inside the exhaust inner trough. The other end of the second transmission belt is connected to the exhaust inner trough and is connected to the insert rod for transmission. The second row fan is connected to the lower end of the insert rod, so that the second row fan is located at one of the corners of the exhaust inner trough. The first motor is installed in the coupling maintenance room. The output shaft of the first motor is coaxially fixed to the transmission shaft of the split transmission shaft frame. The upper end of the transmission shaft rod is coaxially fixed to the transmission shaft of the split transmission shaft frame. The lower end of the transmission shaft rod extends into the exhaust inner trough. The first row fan is installed at the lower end of the transmission shaft rod and is located at another corner of the exhaust inner trough.

[0011] The first and second transmission belts are arranged in parallel, one above the other, and the plane containing the first and second transmission belts is perpendicular to the axis of the first and second exhaust fans.

[0012] The exhaust duct frame includes an upper assembly frame and a lower mounting frame. A groove is formed on the inner wall of the top of the exhaust duct frame, and a mounting block is formed at the top edge of the upper assembly frame. The mounting block can be fitted into the groove, so that the upper assembly frame is assembled on the top of the exhaust duct frame. The lower mounting frame is detachably installed at the bottom of the upper assembly frame. The upper end of the mounting rod is rotatably installed in the lower mounting frame, and the lower end of the mounting rod passes through the lower mounting frame and is coaxially fixed to the second exhaust fan. The other end of the second transmission belt is connected to the mounting rod and is located between the lower mounting frame and the second exhaust fan.

[0013] The mounting bracket is equipped with a first filter assembly, which includes a connecting baffle plate and a rotating filter plate. A pair of connecting baffle plates are symmetrically fixed to the top two sides of the mounting rod, and a pair of hollow parts are formed between the pair of connecting baffle plates. The rotating filter plate has a mounting groove in the middle and is rotatably connected to the top of the mounting rod through the mounting groove. The pair of rotating filter plates can be rotated to cover the pair of hollow parts, or the pair of rotating filter plates can be rotated to be offset from the pair of hollow parts to form an inspection arc groove.

[0014] The air inlet outer trough frame is provided with a second filter assembly, which includes a fixing block and an assembly filter. Several fixing blocks are arranged circumferentially along the inner wall of the air inlet outer trough frame, and the assembly filter is horizontally assembled on several fixing blocks. The assembly filter has a ring structure, so that the assembly filter is coaxially assembled between the air inlet outer trough frame and the air outlet inner trough frame.

[0015] The aforementioned coaxial airflow guiding mechanism includes an installation chamber, an assembly shaft frame, a second motor, a third transmission belt, and an assembly shaft sleeve. The installation chamber is located at the side end of the main body of the device, the assembly shaft frame is located at the bottom of the installation chamber, the output shaft of the second motor is coaxially and fixedly connected to the transmission shaft of the assembly shaft frame, one end of the third transmission belt is drivenly connected to the transmission shaft of the assembly shaft frame, the assembly shaft sleeve is rotatably installed at the bottom of the air inlet outer slot frame, the other end of the third transmission belt is drivenly connected to the assembly shaft sleeve, and the driven airflow guide fan is assembled on the assembly shaft sleeve.

[0016] The multi-port ventilation mechanism includes assembled air ducts and external air ducts; two assembled air ducts are connected to the bottom of the main body of the device and are respectively connected to the air inlet external trough frame and the air outlet internal trough frame. Multiple assembly ports are formed on the side wall of each assembled air duct. One end of multiple external air ducts is respectively assembled onto the two assembled air ducts through multiple assembly ports and locked and fixed. The other end of multiple external air ducts is respectively connected to the underground integrated pipe gallery room that requires ventilation and diversion.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The present invention is equipped with a coupling transmission exhaust mechanism and a guide frame, which can synchronously drive the first exhaust fan and the second exhaust fan through the first motor via the first transmission belt and the second transmission belt. Since the first exhaust fan and the second exhaust fan are both located at the corner of the exhaust trough frame, the exhaust range can be expanded, avoiding the phenomenon of insufficient exhaust air force. At the same time, the exhaust efficiency is further improved by the guide frame set at the corner.

[0019] 2. Because the present invention is equipped with a first filter component and a second filter component, it can filter the air flowing through the air inlet outer trough and the air outlet inner trough, thus preventing the introduction of dust and dirt into the underground integrated pipe gallery room. The first filter component can take into account both filtration and quick maintenance functions through a rotating installation structure. At the same time, the filter screen of the first filter component can be replaced and cleaned through quick disassembly and assembly between the upper and lower mounting frames.

[0020] 3. Because the present invention is equipped with a coupling air guiding and diversion mechanism, the driven air guiding fan can be driven by a motor to perform rotational air guiding operations, so that the main body of the device can perform relative air guiding and diversion operations while exhausting air, thereby achieving the beneficial effect of ventilation and air exchange.

[0021] 4. Because the present invention is equipped with a multi-port ventilation mechanism, it can be connected to the ventilation rooms of each individual underground utility tunnel through external air ducts, so as to achieve the purpose of ventilation and air exchange of the underground utility tunnel.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see the appendix Figure 1 and attached Figure 2 A high-efficiency underground integrated pipe gallery ventilation and air exchange device with air convection function includes a main body 1, a coupling-driven exhaust mechanism 2, a prefabricated dust filter mechanism 3, a coupling-driven air guiding and diversion mechanism 5, and a multi-port ventilation mechanism 6. The prefabricated dust filter mechanism 3 is installed inside the main body 1. The prefabricated dust filter mechanism 3 includes an air inlet outer trough frame 301 and an air outlet inner trough frame 302. The air inlet outer trough frame 301 is located inside one side of the main body 1. The air outlet inner trough frame 302 has several corners forming a Z-shaped structure. One end of the air outlet inner trough frame 302 is located in the upper part of the air inlet outer trough frame 301, and the other end of the air outlet inner trough frame 302 penetrates the side wall of the air inlet outer trough frame 301 and extends to the main body 1. The main body 1 is located on the other side of the interior; the coupling drive exhaust mechanism 2 is located on the other side of the interior of the main body 1, and the coupling drive exhaust mechanism 2 includes several exhaust fans, which are correspondingly located at several corners in the exhaust inner trough 302; the coupling air guiding mechanism 5 is located on the side end of the main body 1, and the coupling air guiding mechanism 5 includes a driven air guiding fan 506, which is located in the lower part of the air inlet outer trough 301; one end of the two multi-port ventilation mechanisms 6 is respectively connected to the main body 1 at intervals and communicates with the air inlet outer trough 301 and the exhaust inner trough 302, and the other end of the two multi-port ventilation mechanisms 6 is connected to multiple underground integrated pipe gallery rooms.

[0031] Several exhaust fans of the coupling-driven exhaust mechanism 2 assist in exhaust at the corners of the ductwork in the inner exhaust duct frame 302, expanding the exhaust range and preventing insufficient airflow at these corners. The driven guide fan 506 of the coupling-driven airflow guiding mechanism 5 rotates to guide airflow, allowing the main body 1 to perform relative airflow guidance while exhausting air, thus achieving ventilation for the underground utility tunnel rooms. The size and number of the multi-port ventilation mechanism 6 can be adjusted adaptively according to the size and number of the outer air inlet duct frame 301 and the inner exhaust duct frame 302. The number of corners in the inner exhaust duct frame 302 can be adjusted according to the actual installation situation, preferably two, and the number of exhaust fans should match the number of corners in the inner exhaust duct frame 302.

[0032] Please see the appendix Figure 1 The exhaust inner trough frame 302 is provided with a flow guide frame 4, which is inclinedly set at the corner of the exhaust inner trough frame 302 to improve the exhaust efficiency.

[0033] Please see the appendix Figure 1 The coupling-driven exhaust mechanism 2 includes a coupling maintenance chamber 201, an assembly base plate 202, a split-direction drive shaft frame 203, a first drive belt 204, a driven drive shaft frame 205, a second drive belt 206, a first motor 207, a drive shaft rod 208, a first exhaust fan 209, and a second exhaust fan 210. The coupling maintenance chamber 201 is located on the other side inside the main body 1, between several corners of the exhaust inner trough frame 302. The assembly base plate 202 is located at the bottom inside the coupling maintenance chamber 201. The split-direction drive shaft frame 203 and the driven drive shaft frame 205 are respectively installed on the assembly base plate 202 at intervals. The first drive belt 204 is drivingly connected between the split-direction drive shaft frame 203 and the driven drive shaft frame 205. One end of the second drive belt 206 is drivingly connected to the split-direction drive shaft frame 204. On the drive shaft bracket 203, an insert rod 309 is rotatably installed inside the exhaust inner slot bracket 302. The other end of the second transmission belt 206 is connected to the exhaust inner slot bracket 302 and is connected to the insert rod 309 for transmission. The second exhaust fan 210 is connected to the lower end of the insert rod 309, so that the second exhaust fan 210 is located at one corner of the exhaust inner slot bracket 302. The first motor 207 is installed in the coupling maintenance chamber 201. The output shaft of the first motor 207 is coaxially fixed to the transmission shaft of the split transmission shaft bracket 203. The upper end of the transmission shaft rod 208 is coaxially fixed to the transmission shaft of the split transmission shaft bracket 203. The lower end of the transmission shaft rod 208 extends into the exhaust inner slot bracket 302. The first exhaust fan 209 is installed at the lower end of the transmission shaft rod 208 and is located at another corner of the exhaust inner slot bracket 302.

[0034] The first row fan 209 forms an axial transmission structure with the first motor 207 via the drive shaft 208, the driven drive shaft bracket 205, the first drive belt 204, and the branch drive shaft bracket 203. The first drive belt 204 and the second drive belt 206 are distributed in parallel. The branch drive shaft bracket 203 is distributed in two layers, so that it can connect the first drive belt 204 and the second drive belt 206 at the same time. When the first motor 207 is started, it can drive the first row fan 209 and the second row fan 210, which are connected to the first drive belt 204 and the second drive belt 206, to perform the same speed coupling transmission operation, so as to expand the exhaust range.

[0035] Please see the appendix Figure 1 The first transmission belt 204 and the second transmission belt 206 are arranged in parallel, upper and lower layers, and the plane containing the first transmission belt 204 and the second transmission belt 206 is perpendicular to the axial direction of the first row fan 209 and the second row fan 210. The same first motor 207 can drive the first transmission belt 204 and the second transmission belt 206 synchronously, thereby enabling the first row fan 209 and the second row fan 210 to rotate at a continuous speed.

[0036] Please see the appendix Figure 2 The exhaust inner trough frame 302 is provided with an upper mounting frame 306 and a lower mounting frame 307. A groove 305 is formed on the inner wall of the top of the exhaust inner trough frame 302. An mounting block is formed at the top edge of the upper mounting frame 306. The mounting block can be fitted into the groove 305, so that the upper mounting frame 306 is mounted on the top of the exhaust inner trough frame 302. The lower mounting frame 307 is detachably mounted on the bottom of the upper mounting frame 306 through a first threaded assembly 308. The upper end of the insert rod 309 is rotatably mounted in the lower mounting frame 307 through a rotating bearing. The lower end of the insert rod 309 passes through the lower mounting frame 307 and is coaxially fixed to the second exhaust fan 210. The other end of the second transmission belt 206 is connected to the insert rod 309 and is located between the lower mounting frame 307 and the second exhaust fan 210.

[0037] The upper mounting frame 306 forms a fitting assembly structure with the inner exhaust duct frame 302 through the groove 305, and the upper mounting frame 306 forms a detachable structure with the lower mounting frame 307 through the first threaded assembly 308. The upper mounting frame 306 and the lower mounting frame 307 are integrated. The groove 305 provided inside the top of the inner exhaust duct frame 302 makes it easy for the user to insert it into the middle of the inner exhaust duct frame 302. At the same time, the upper mounting frame 306 and the lower mounting frame 307 are connected by the thread formed by the first threaded assembly 308 itself, which makes disassembly and reassembly convenient.

[0038] Please see the appendix Figure 2 To be continued Figure 4The mounting bracket 307 is equipped with a first filter assembly, which includes a connecting baffle plate 310 and a rotating filter plate 311. A pair of connecting baffle plates 310 are symmetrically fixed to the top two sides of the mounting rod 309, and a pair of hollow parts are formed between the pair of connecting baffle plates 310. The rotating filter plate 311 has a mounting groove 312 in the middle and is rotatably connected to the top of the mounting rod 309 through the mounting groove 312. The pair of rotating filter plates 311 can be rotated to cover the pair of hollow parts, or the pair of rotating filter plates 311 can be rotated to be offset from the pair of hollow parts, forming an inspection arc groove 313.

[0039] The rotating filter plate 311, through the embedded groove 312, the embedded rod 309, and the mounting frame 306, forms an embedded assembly structure, and the rotating filter plate 311 and the maintenance arc groove 313 are interconnected. A pair of connecting baffles 310 and a pair of rotating filter plates 311 can prevent dust and other contaminants from entering the exhaust inner frame 302 with the air. When it is necessary to clean or replace the conversion filter plate 311 carried in the middle of the mounting frame 307, the mounting frame 306 can be removed. At the same time, when the pair of rotating filter plates 311 can be rotated to be offset from the pair of embedded grooves 312, the inside of the mounting frame 307 can be inspected through the maintenance arc groove 313.

[0040] Please see the appendix Figure 2 The air inlet outer trough frame 301 is provided with a second filter assembly, which includes a fixing block 303 and an assembly filter 304. Several fixing blocks 303 are arranged circumferentially along the inner wall of the air inlet outer trough frame 301, and the assembly filter 304 is horizontally assembled on several fixing blocks 303. The assembly filter 304 has a ring structure, so that the assembly filter 304 is coaxially assembled between the air inlet outer trough frame 301 and the air outlet inner trough frame 302.

[0041] The fixed block 303 and the air inlet outer trough frame 301 are fixed as one unit. The assembled filter screen 304 is mounted on the top of the fixed block 303. When the main body 1 of the device is performing ventilation operation, the presence of the assembled filter screen 304 can prevent external dust and debris from falling into the middle of the air inlet outer trough frame 301, thereby preventing dust and dirt from being brought into the ventilation room of the underground integrated pipe gallery connected to the other end of the multi-port ventilation mechanism 6.

[0042] Please see the appendix Figure 5The coupling air guiding and diversion mechanism 5 includes an installation chamber 501, an assembly shaft frame 502, a second motor 503, a third transmission belt 504, and an assembly shaft sleeve 505. The installation chamber 501 is located at the side end of the main body 1 of the device. The assembly shaft frame 502 is located at the bottom of the installation chamber 501. The output shaft of the second motor 503 is coaxially and fixedly connected to the transmission shaft of the assembly shaft frame 502. One end of the third transmission belt 504 is connected to the transmission shaft of the assembly shaft frame 502. The assembly shaft sleeve 505 is rotatably installed at the bottom of the air inlet outer slot frame 301 through the mounting accessory 507. The other end of the third transmission belt 504 is connected to the assembly shaft sleeve 505. The driven guide fan 506 is mounted on the assembly shaft sleeve 505.

[0043] The driven guide fan 506 forms a coupling transmission structure with the second motor 503 through the assembly bushing 505, the third transmission belt 504, the assembly shaft bracket 502, and the assembly bushing 505 and the assembly part 507 are connected. When the second motor 503 is started, it transmits its own power to the assembly shaft bracket 502 and drives the driven guide fan 506 to rotate, so as to achieve the purpose of guiding airflow.

[0044] Please see the appendix Figure 6 The multi-port ventilation mechanism 6 includes an assembly duct 601 and an external duct 603. Two assembly ducts 601 are connected to the bottom of the main body 1 of the device and are respectively connected to the air inlet outer trough frame 301 and the air outlet inner trough frame 302. Multiple assembly ports 602 are formed on the side wall of each assembly duct 601. One end of multiple external ducts 603 is respectively assembled onto the two assembly ducts 601 through multiple assembly ports 602 and locked and fixed by the second threaded assembly 604. The other end of multiple external ducts 603 is respectively connected to the underground integrated pipe gallery room that needs ventilation and diversion.

[0045] Underground utility tunnels typically consist of large areas and numerous individual rooms. The assembly ports 602 distributed along the sides of the duct 601 and the external duct 603 are aligned and assembled, and the threaded structure of the second threaded assembly 604 is used to limit and fix them, thus achieving external connection to each room requiring ventilation and airflow distribution. Preferably, the second threaded assembly 604 can be a bolt and nut assembly.

[0046] Please see the appendix Figure 1 To be continued Figure 6 The working process and working principle of this invention are as follows:

[0047] The split drive shaft bracket 203 is distributed in two layers, so that it can connect the first drive belt 204 and the second drive belt 206 at the same time. When the first motor 207 is started, it can drive the first drive belt 204 and the second drive belt 206 at the same time, so that the first exhaust fan 209 and the second exhaust fan 210 can perform the same speed coupling drive operation.

[0048] By setting up the first exhaust fan 209 and the second exhaust fan 210 and arranging them at the corners of the exhaust duct frame 302, the exhaust range is expanded, reducing the phenomenon of insufficient exhaust force due to individual corners during the exhaust process. Furthermore, if necessary, guide frames 4 are installed at one or more corners to further improve the exhaust efficiency.

[0049] The filter screen 304 is mounted on top of the fixed block 303. When the main body 1 of the device is performing ventilation operation, the filter screen 304 can prevent external dust and debris from falling into the air inlet frame 301, thereby preventing dust and dirt from being brought into the ventilation room of the underground integrated pipe gallery connected to the other end of the external air duct 603 of the multi-port ventilation mechanism 6.

[0050] The upper frame 306 and the lower frame 307 are assembled as a single unit via the first threaded assembly 308. The recess 305 inside the top of the exhaust inner frame 302 facilitates easy insertion by the user. The rotating filter plate 311 and the connecting baffle plate 310 block and filter the air flowing through the exhaust inner frame 302, preventing dust and dirt from being introduced into the ventilation system of the connected underground utility tunnel. When the rotating filter plate 311 needs to be replaced or cleaned, the upper frame 306 can be quickly disassembled via the first threaded assembly 308. The first threaded assembly 308 can be a bolt and nut assembly.

[0051] When maintenance is required, the rotating collar can be rotated relative to the mounting rod 309. A pair of rotating filter screens 311 rotate synchronously with the rotating collar, so that the rotating filter screens 311 are misaligned with the hollow part, exposing the maintenance arc groove 313. Simple maintenance can then be carried out through the maintenance arc groove 313 without the need for complete disassembly, saving time and effort and improving maintenance efficiency.

[0052] Start the second motor 503, which drives the transmission shaft of the assembly shaft frame 502 to rotate synchronously. The assembly shaft frame 502 drives the third transmission belt 504 and the assembly shaft sleeve 505 and driven guide fan 506 connected to it to perform rotational air diversion operation, so that the main body of the device 1 can perform relative air diversion and air guiding operation while exhausting air, thereby achieving the effect of ventilation and air exchange.

[0053] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
