Description

Technical Field

[0001] This utility model relates to the field of tunnel ventilation technology, and specifically to a tunnel ventilation system. Background Technology

[0002] Tunnels are generally defined as underground chambers or caverns with a cross-sectional area greater than 2 square meters, built within a mountain or underground structure. Their core function is to provide passageways through obstacles (such as mountains or waterways) or utilize underground space. With the rapid development of infrastructure construction, tunnel engineering, as an important transportation infrastructure project, places particular emphasis on safety during its construction. During tunnel construction, the ventilation system is a key factor in ensuring the safety of construction personnel and improving construction efficiency.

[0003] The existing technology has the following problems:

[0004] During tunnel construction, a ventilation system is used to transport outside air into the tunnel. However, in existing tunnel ventilation systems, the air contains a certain amount of dust, and dust collection is inconvenient. In addition, existing tunnel ventilation systems typically use fans to transport air, and the connection between the fans and ducts is integrated. When the fans are damaged or malfunction, it is not convenient to replace or repair them, resulting in the inability to ventilate the tunnel in a timely manner.

[0005] Therefore, we need a tunnel ventilation system to solve the above problems. Utility Model Content

A collection box is slidably connected to the lower side of the inner wall of the collection box. The upper surface of the collection box overlaps with the lower surface of the filter screen. Four limiting components are arranged in a circular array on the outer surface of the outer shell.

[0010] A further improvement of this utility model is that a second filter screen is fixedly connected to the middle of the inner wall of the collection box, and the mesh of the second filter screen is larger than that of the first filter screen.

[0011] A further improvement of the present invention is that: a rotating shaft is movably connected to the center of the front of the collection box, and limiting rings are fixedly connected to the front and rear of the outer surface of the rotating shaft. A U-shaped handle is attached to the opposite face of the front and rear limiting rings, and the outer surface of the rotating shaft is movably connected to the interior of the U-shaped handle.

[0012] A further improvement of this utility model is that: the outer surface of the U-shaped handle in the horizontal direction is provided with grooves, and an L-shaped limiting block is magnetically fixedly connected inside the groove. The depth of the groove is greater than the vertical length of the L-shaped limiting block. The outer surface of the L-shaped limiting block in the horizontal direction is fixedly connected to the surface of the collection box. The grooves and L-shaped limiting blocks above and below are mirror images of each other.

[0013] A further improvement of this utility model is that: a protective net is fixedly connected to the left side of the inner wall of the outer shell, a fan is installed on the inner wall of the outer shell, the fan is composed of a motor and fan blades, and four grooves that are interconnected inside and outside are formed in a circular array on the right side of the outer surface of the outer shell.

[0014] A further improvement of the present invention is that: each of the four limiting components includes a fixing block and a mounting plate, the outer surface of the fixing block overlaps with the inside of the groove in the outer shell, the outer surface of the fixing block is fixedly connected to the surface of the ventilation pipe, and the outer surface of the mounting plate is fixedly connected to the surface of the outer shell.

[0015] A further improvement of the present invention is that: an elastic plate is fixed on the upper left side of the fixing block, a limiting groove is opened on the left side of the elastic plate, a slot is opened on the lower left side of the mounting plate, the inside of the slot is inserted into the outer surface of the elastic plate, a blocking block is fixedly connected to the left side of the upper surface of the elastic plate, and the right side of the blocking block overlaps with the surface of the mounting plate.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] This utility model provides a tunnel ventilation system. During use, a fan facilitates air delivery and ventilation. The clean air is discharged into the tunnel through ventilation pipes and a collection box, thus achieving tunnel ventilation. As air is delivered, it enters the collection box and is guided into the box by a guide plate. Dust in the air is filtered by two filters. Furthermore, the dust collected during filtration is temporarily stored in the collection box, achieving dust collection during tunnel ventilation.

[0019] This utility model provides a tunnel ventilation system. In use, the worker rotates the connecting block to separate the locking block from the limiting groove, and the worker presses the blocking block to deform the elastic plate, causing the blocking block to separate from the surface of the mounting plate. The worker then rotates the connecting block again to allow the lower locking block to enter the limiting groove. At this time, the elastic plate is in a bent positioning state. The worker then moves the outer shell to separate it from the ventilation pipe, which facilitates subsequent replacement and maintenance work. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1: As Figures 1 to 6 As shown, this utility model provides a tunnel ventilation system, including an outer shell 1, with a protective net 12 fixedly connected to the left side of its inner wall. The protective net 12 can prevent large foreign objects from entering the interior of the outer shell 1 and protect internal components such as the fan 11. The fan 11 is installed on the inner wall of the outer shell 1. The fan 11 consists of a motor and fan blades. In addition, the fan 11 is electrically connected to the power supply via wires. The motor drives the fan blades to rotate, generating airflow to achieve the ventilation function, so that the air is delivered to the interior of the ventilation pipe 2 and the collection box 3 for easy exhaust. Four grooves with internal and external communication are formed in a ring array on the right side of the outer surface of the outer shell 1 to provide a position for the installation of the limiting component 13 and prevent the outer shell 1 from rotating.

[0029] The outer surface of the ventilation duct 2 is fitted into the inside of the outer shell 1. Support seats 4 are fixedly connected to the left and right sides of the outer surface of the ventilation duct 2. The support seats 4 serve to support the ventilation duct 2.

[0030] Example 2: Figures 1 to 6As shown, the collection box 3 is located at the right end of the outer shell 1. Circular openings 31, communicating with each other, are provided on both the left and right sides of the inner wall of the collection box 3. The inner wall of the left circular opening 31 is fixedly connected to the outer surface of the ventilation pipe 2. A pipe can be installed in the right circular opening 31 to deliver clean air into the tunnel, allowing the airflow in the ventilation pipe 2 to enter the collection box 3. An inclined air guide plate 32 is fixedly connected to the left side of the inner wall of the collection box 3. The air guide plate 32 directs the airflow entering the collection box 3 in a specific direction, facilitating subsequent filtration operations. A filter screen 33 is fixedly connected to the lower right side of the air guide plate 32. The right side of the filter screen 33 is fixedly connected to the inner wall of the collection box 3. 3 can filter smaller impurities and dust in the airflow, and the filter screen 33 is installed horizontally, which also facilitates the entry of dust in the air into the collection box 34. The lower part of the inner wall of the collection box 3 is slidably connected to the collection box 34. The upper surface of the collection box 34 overlaps with the lower surface of the filter screen 33. The second filter screen 341 is fixedly connected to the middle of the inner wall of the collection box 34. The mesh of the second filter screen 341 is larger than that of the filter screen 33, which can provide a preliminary filtration effect for larger impurities and dust in the air. A rotating shaft is movably connected to the middle of the front of the collection box 34. Limiting rings are fixedly connected to the front and rear of the outer surface of the rotating shaft. The opposite surfaces of the front and rear limiting rings overlap with a U-shaped joint. The U-shaped handle 342 has a through-hole connection between its outer surface and the interior. Front and rear limiting rings restrict its position, preventing it from disengaging and ensuring rotation. Rotating the handle allows the collection box 34 to be easily pulled out or pushed into the collection container 3, facilitating subsequent dust cleaning. The outer surface of the U-shaped handle 342 has grooves 343 on each side, with L-shaped limiting blocks 344 magnetically attached inside. The L-shaped limiting blocks 344 are magnetic, while the U-shaped handle 342 is metal. The magnetic connection is achieved by using a groove 343 with a depth greater than the vertical length of the L-shaped limiting block 344. This allows the U-shaped handle 342 to rotate in an arc shape without causing the groove 343 to collide with or obstruct the surface of the L-shaped limiting block 344. The horizontal outer surface of the L-shaped limiting block 344 is fixedly connected to the surface of the collection box 3. The upper and lower grooves 343 and L-shaped limiting blocks 344 are mirror images of each other. When the collection box 34 is pushed into the collection box 3, the rotation of the U-shaped handle 342 by the worker causes the groove 343 to contact and magnetically fix with the L-shaped limiting block 344, thus restricting the position of the collection box 34 and preventing it from sliding freely.

[0031] Example 3: Figures 1 to 6As shown, four limiting components 13 are arranged in a circular array on the outer surface of the housing 1. Each limiting component 13 includes a fixing block 131 and a mounting plate 133. The outer surface of the fixing block 131 overlaps with the inside of the groove in the housing 1, and the outer surface of the fixing block 131 is fixedly connected to the surface of the ventilation pipe 2. The outer surface of the mounting plate 133 is fixedly connected to the surface of the housing 1. An elastic plate 132 is fixedly fixed on the upper left side of the fixing block 131. The elastic plate 132 has elastic deformation capability, which facilitates the subsequent installation and removal of the housing 1. A limiting groove 136 is opened on the left side of the elastic plate 132. The setting of the limiting groove 136 facilitates the insertion of the locking block 138, so that the elastic plate 132 remains horizontal after the housing 1 is installed and will not bend. A slot 135 is opened on the lower left side of the mounting plate 133. The inside of the slot 135 is inserted into the outer surface of the elastic plate 132. A blocking block 134 is fixedly connected to the left side of the upper surface of the elastic plate 132. The left side of the blocking block 134 is provided with a slope, which facilitates subsequent installation. The inclined plane is pressed, causing the elastic plate 132 to bend. The right side of the blocking block 134 overlaps with the surface of the mounting plate 133. The blocking block 134 facilitates position restriction. Through the insertion of the elastic plate 132 into the slot 135 and the blocking effect of the blocking block 134, the initial connection and positioning of the outer shell 1 and the ventilation pipe 2 can be achieved. The front and rear sides of the left side of the mounting plate 133 are movably connected to the connecting blocks 137. The surface of the mounting plate 133 and the surface of the connecting blocks 137 are magnetically fixed. The magnetic fixation between the two facilitates subsequent installation work. Two locking blocks 138 are fixedly connected to the opposite surfaces of the front and rear connecting blocks 137. The outer surface of the front and rear locking blocks 138 overlaps and presses against the inside of the limiting groove 136. The material of the front and rear locking blocks 138 is rubber. The rubber material of the locking blocks 138 can increase the friction with the limiting groove 136, so that the two are in a tight fit and are not easy to loosen. This ensures that the elastic plate 132 is always in a horizontal state and will not bend after the outer shell 1 and the ventilation pipe 2 are installed.

[0032] In addition, during installation, rotating the connecting block 137 causes the front and rear connecting blocks 137 to be in a figure-eight shape and magnetically fixed. Then, the worker moves the outer shell 1 and fits it onto the outer surface of the ventilation pipe 2. At the same time, the worker presses the inclined surface of the blocking block 134 to cause the elastic plate 132 to bend. When the outer shell 1 moves to the appropriate position, the elastic plate 132 resets and is limited by the blocking block 134. The worker then rotates the connecting block 137 to insert the upper locking block 138 into the limiting groove 136 for limiting, thereby completing the installation.

[0033] Working principle: In use, the fan 11 first transports air from outside the tunnel. After being transported, the air passes through the ventilation pipe 2 and the inside of the collection box 3, and then enters the pipe in the circular opening 31 on the right, facilitating the delivery of clean air into the tunnel. When the air enters the collection box 3, due to the inclined design of the air guide plate 32, the transported air enters the collection box 34 and is filtered by filter screen 2 341 and filter screen 1 33. The filter screen 2 341 initially filters larger dust impurities, while the filter screen 1 33 filters smaller dust impurities before the air enters the pipe for discharge. When the transported air enters the collection box 34, the filtered dust impurities also enter the collection box 34 for easy collection.

[0034] During tunnel construction, workers need to clean the dust in the collection box 34 regularly. By turning the U-shaped handle 342, the groove 343 is separated from the L-shaped limiting block 344, and then the collection box 34 is pulled out from the inside of the collection box 3, which facilitates the dust cleaning of the collection box 34.

[0035] The worker rotates the connecting block 137 to separate the upper locking block 138 from the interior of the limiting groove 136. Then, by pressing the blocking block 134, the blocking block 134 is separated from the surface of the mounting plate 133. At this time, the elastic plate 132 is in a deformed and bent state. Then, by rotating the connecting block 137, the worker rotates the lower locking block 138 into the interior of the limiting groove 136 to position the deformed and bent elastic plate 132. By repeating the above steps, the steps for the other limiting components 13 are completed. When all are completed, the worker moves the outer shell 1 to separate the outer shell 1 from the ventilation pipe 2, thereby completing the disassembly operation and facilitating subsequent replacement and maintenance work.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
