Description

Technical Field

[0001] This utility model relates to the field of waste gas collection technology, specifically to a device for collecting and discharging toxic and harmful gases. Background Technology

[0002] During underground construction, the risk of harmful gases escaping and injuring workers remains constant. Currently, common gas collection and emission devices in construction tunnels have fixed structures, making them difficult to move and accurately target areas prone to gas escape. Furthermore, these devices lack structural flexibility, often occupying significant space and causing congestion in the surrounding environment. Workers walking in these areas are not only more likely to bump into the devices, reducing the overall safety of the underground tunnel, but also increase the potential risk of damage to the devices. Utility Model Content

[0003] The purpose of this utility model is to provide a collection and emission device for toxic and harmful gases. The device is composed of a support assembly and a telescopic transfer box. The telescopic transfer box can be moved along the length of the support assembly by a moving assembly, which makes it easy to quickly adjust the telescopic transfer box to point towards the gas escape area, thereby improving the efficiency of the device in collecting escaped gases. At the same time, the silicone connecting sleeve makes the first installation box and the second installation box form a telescopic structure, which can not only expand the collection space and increase the collection volume when in use, but also reduce the space occupied by the device when not in use by shrinking it, thereby reducing the impact on underground engineering construction.

[0004] This utility model is achieved through the following technical solution:

[0005] A device for collecting and discharging toxic and harmful gases, comprising:

[0006] A support assembly is provided along the wall of the underground engineering passage;

[0007] A telescopic transfer box, wherein the telescopic transfer box is connected to the lower surface of the support component via a movable component and moves along the length direction of the support component;

[0008] The telescopic transfer box includes a first installation box, a silicone connecting sleeve, and a second installation box. The two ends of the silicone connecting sleeve are respectively connected to the first installation box and the second installation box, so that the first installation box and the second installation box can be far apart or close to each other. The interiors of the first installation box, the silicone connecting sleeve, and the second installation box together form a cavity for collecting toxic and harmful gases.

[0009] In this solution, the telescopic transfer box is connected to the lower surface of the support component via a movable component, allowing it to move along the length of the support component. This enables the device to flexibly adjust its position and precisely target the escaping point of toxic and harmful gases, thereby improving the efficiency of gas collection. The telescopic transfer box includes a first installation box, a silicone connecting sleeve, and a second installation box. The silicone connecting sleeve allows the first and second installation boxes to move away from or closer to each other. The cavity formed by the three boxes is used to collect toxic and harmful gases. This telescopic structure not only expands the collection space and increases the collection volume when in use, but also reduces the footprint of the device by retracting when not in use, thus reducing the impact on underground construction. Overall, it achieves the function of efficiently collecting toxic and harmful gases while also making good use of construction space.

[0010] As an optimized solution for the collection and emission device, the support assembly includes a long plate, the upper surface of which is fixed to the upper wall of the underground engineering passage, and the lower surface of which is fixed to a designated position by multiple support rods.

[0011] In this design, the upper surface of the long plate is fixed to the upper wall of the underground engineering passage. This avoids excessively occupying space within the passage, thus preventing disruption to the normal passage and operations of construction personnel, while also ensuring that the entire device is positioned at a relatively high level, facilitating the collection of toxic and harmful gases escaping from different locations. Simultaneously, the lower surface of the long plate is fixed to designated positions by multiple support rods. These support rods evenly distribute the weight of the long plate and the telescopic transfer box connected below it, enhancing the stability of the entire support assembly and preventing any impact on gas collection and emission efficiency due to shaking or displacement during operation.

[0012] As an optimized solution for the collection and emission device, the mobile component includes a mounting plate, the lower surface of which is provided with a groove that matches the mounting plate, and the lower end of the mounting plate is connected to the telescopic transfer box, so that the telescopic transfer box moves synchronously with the mounting plate.

[0013] In this design, the mounting plate in the moving component matches the groove on the lower surface of the long plate, providing a stable moving track for the telescopic transfer box. This allows the telescopic transfer box to move flexibly along the length of the long plate and quickly adjust to the optimal collection point based on the location of the toxic or harmful gas escape, greatly improving the accuracy and efficiency of the device in collecting gases.

[0014] As an optimized solution for the collection and emission device, the mounting plate is rotatably connected to the telescopic transfer box via a connecting shaft.

[0015] In this design, the connecting shaft allows the telescopic transfer box to rotate relative to the mounting plate. Once the telescopic transfer box has moved to the approximate gas escape area, its angle can be flexibly adjusted according to the actual gas flow direction and escape angle, allowing the collection port to more accurately align with the gas escape point, thus improving the efficiency and quality of gas collection. This rotating connection method also increases the adaptability of the device in complex construction environments. Even in narrow or complex underground engineering tunnels, the telescopic transfer box can be rotated to avoid obstacles and better approach the gas source for collection, effectively compensating for the shortcomings of fixed structure devices in dealing with different construction scenarios.

[0016] As an optimized solution for the collection and emission device, the lower surfaces of the No. 1 installation box and the No. 2 installation box are respectively fixedly connected to the No. 1 support frame and the No. 2 support frame, and the lower ends of the No. 1 support frame and the No. 2 support frame are in contact with the ground.

[0017] In this solution, the underground construction environment is complex, often with uneven ground and construction vibrations. These two support frames can distribute the weight of the transfer box, ensuring its stability and reliability during operation, preventing shaking or tipping, and guaranteeing the stability of the device operation.

[0018] As an optimized solution for the collection and discharge device, a socket rod is fixedly connected to the lower end of the second support frame, and a socket hole is opened at the lower end of the first support frame. The end of the socket rod away from the second support frame is engaged with the socket hole.

[0019] In this design, the socket rod at the lower end of support frame No. 2 interlocks with the socket hole at the lower end of support frame No. 1. When the device is not in use or is stored, it securely connects support frames No. 1 and No. 2, thereby enhancing the stability of the entire telescopic transfer box in its stored state. When the underground construction environment is subject to ground vibration or interference from personnel or equipment activity, this interlocking structure effectively prevents relative displacement of the two support frames, avoiding shaking or tipping of the telescopic transfer box, reducing the risk of device damage, and also minimizing the impact on the surrounding construction environment.

[0020] As an optimized solution for the collection and emission device, an air extraction mechanism is fixedly connected inside the No. 1 installation box, and the air inlet of the air extraction mechanism penetrates through the left surface of the No. 1 installation box. An activated carbon filter box is installed inside the No. 2 installation box, and an air outlet is fixedly connected to the right surface of the No. 2 installation box.

[0021] In this design, the fixed extraction mechanism inside the No. 1 installation box has its air inlet penetrating the box wall, which can actively extract toxic and harmful gases, providing power for gas collection and ensuring that the device can quickly and efficiently gather harmful gases that have escaped from the construction environment. The activated carbon filter box installed in the No. 2 installation box can purify the extracted gas, effectively adsorbing the toxic and harmful substances in it, greatly reducing the harm of the emitted gas to the environment and personnel. The air outlet connected to the right surface of the No. 2 installation box is the discharge channel for the treated gas, allowing the purified gas to be safely discharged to the designated area.

[0022] As an optimized solution for the collection and emission device, a limiting frame for isolation is provided between the air extraction mechanism and the activated carbon filter box.

[0023] In this design, the limiting frame creates a barrier between the air extraction mechanism and the activated carbon filter box, effectively preventing them from coming into contact with each other during device operation due to vibration, collision, or other reasons.

[0024] As an optimized solution for the collection and emission device, the silicone connecting sleeve has a folded structure.

[0025] In this design, when collecting toxic and harmful gases, the internal space for gas collection in the transfer box can be expanded by stretching the folding structure, thereby increasing the gas collection volume and meeting the collection needs of gases with different concentrations and ranges. When the device is not in use or needs to be stored, the folding structure can be quickly folded, greatly reducing the space occupied by the device, minimizing the impact on underground construction areas, and facilitating flexible arrangement and movement of the device within limited construction space. In addition, the silicone connecting sleeve of the folding structure has a certain degree of elasticity and cushioning performance, effectively absorbing impact force when the device is subjected to collisions or vibrations, protecting components such as the air extraction mechanism and activated carbon filter box inside the No. 1 and No. 2 installation boxes.

[0026] As an optimized solution for the collection and emission device, a flared connector is provided on the left surface of the No. 1 installation box, and the flared connector is fixedly connected to the air inlet end of the air extraction mechanism.

[0027] In this design, the flared connector increases the opening area of ​​the air intake end of the suction mechanism. When collecting toxic and harmful gases, this expands the suction range, allowing the device to collect gases escaping from different angles and greater distances more efficiently, thus improving the device's gas collection efficiency. Furthermore, the flared shape helps guide gas more smoothly into the suction mechanism, reducing resistance during the intake process and further enhancing the suction effect.

[0028] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0029] 1. The telescopic transfer box of this utility model moves along the length of the support component through the moving component, which allows the device to flexibly adjust its position and accurately target the escaping point of toxic and harmful gases, thereby improving the efficiency of gas collection. At the same time, the silicone connecting sleeve makes the No. 1 installation box and the No. 2 installation box form a telescopic structure, which can not only expand the collection space and increase the collection volume when in use, but also reduce the space occupied by the device when not in use, thereby reducing the impact on underground engineering construction. Compared with traditional devices, this utility model effectively solves the problem of space congestion, reduces the risk of workers colliding with the device, and avoids the gas treatment efficiency being affected by the small collection space.

[0030] 2. This utility model also has a connecting shaft connecting the mounting plate and the telescopic transfer box. This connecting shaft allows the telescopic transfer box to rotate relative to the mounting plate. Combined with the feature that the telescopic transfer box can move along the length of the support component through the movable component, after the telescopic transfer box moves to the approximate gas escape area, it can flexibly adjust its angle according to the actual gas flow direction and escape angle, so that the collection port is more accurately aligned with the gas escape point, thereby improving the efficiency and quality of gas collection.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0039] Example 1

[0040] This embodiment 1 provides a device for collecting and emitting toxic and harmful gases, such as... Figures 1-4 As shown, it includes a support assembly and a telescopic transfer box 17.

[0041] Among them, such as Figure 1 As shown, the support assembly includes a long plate 1 and multiple support rods 2. The upper surface of the long plate 1 is fixed to the upper wall of the underground engineering passage and arranged along the length of the passage. This installation method avoids occupying too much internal space of the passage and does not hinder the normal passage and construction operations of construction personnel. Of course, when the width of the underground engineering passage is relatively wide, it is also possible to arrange the long plate 1 along the length of the passage and arrange multiple sets of this device at intervals along the length of the passage, but this installation method is more expensive. The lower surface of the long plate 1 is fixed to a designated position by multiple support rods 2. The multiple support rods 2 are evenly distributed, which can effectively distribute the weight of the long plate 1 and other components connected to it below, enhance the stability of the entire support assembly, and ensure that the device will not shake or shift during operation, thus ensuring the smooth progress of gas collection and emission.

[0042] Among them, such as Figure 2 and Figure 3 As shown, the telescopic transfer box 17 is connected to the lower surface of the long plate 1 via a moving component and moves along the length of the long plate 1. Specifically, the moving component includes a mounting plate 11, and a groove 8 matching the mounting plate 11 is provided on the lower surface of the long plate 1. The mounting plate 11 is slidably connected inside the groove 8, and the lower end of the mounting plate is connected to the telescopic transfer box 17, so that the telescopic transfer box 17 can move synchronously along the groove with the mounting plate 11. Construction personnel can quickly move the telescopic transfer box 17 to the corresponding area according to the location of the toxic and harmful gas, thereby improving the accuracy and efficiency of gas collection. The movement can be driven by a motor or manually, causing the mounting plate 11 to reciprocate along the groove 8.

[0043] Meanwhile, the telescopic transfer box 17 includes a first installation box 5, a silicone connecting sleeve 6, and a second installation box 7. The left and right ends of the silicone connecting sleeve 6 are fixedly connected to the first installation box 5 and the second installation box 6, respectively. The interiors of the first installation box 5, the silicone connecting sleeve 6, and the second installation box 7 together form a cavity for collecting toxic and harmful gases. The silicone connecting sleeve 6 is a folding telescopic structure or an elastic telescopic structure. In this embodiment, the surface of the silicone connecting sleeve 6 is provided with creases, i.e., a folded structure, so that the first installation box and the second installation box can move away from or close to each other. When the device is not in use, the silicone connecting sleeve 6 is in a folded storage state, at which time the device occupies little space. When in use, pulling the second installation box 7 can extend the folded silicone connecting sleeve 6, increasing the volume of the telescopic transfer box 17 and expanding the gas collection space.

[0044] Meanwhile, to ensure the efficiency and effectiveness of the telescopic transfer box 17 in collecting the escaped gas, such as Figure 4 As shown, an air extraction mechanism 15 is fixedly connected inside the first installation box 5. The air inlet of the air extraction mechanism 15 penetrates the left surface of the first installation box 5 and is used to actively extract toxic and harmful gases. An air outlet 9 is fixedly connected to the right surface of the second installation box 7 and is used to discharge the treated gas. An activated carbon filter box 14 is connected inside the second installation box 7. The activated carbon filter box 14 and the air outlet 9 are distributed opposite each other on the left and right sides, which can filter and purify the collected gas, remove toxic and harmful substances, and ensure that the emitted gas meets safety standards.

[0045] Example 2

[0046] This embodiment 2 provides a device for collecting and emitting toxic and harmful gases, based on embodiment 1. Figures 1-4 As shown, to compensate for the shortcomings of fixed structure devices in dealing with different construction scenarios, the mounting plate 11 is rotatably connected to the upper surface of the first mounting box 5 via the connecting shaft 13. The connecting shaft 13 allows the telescopic transfer box 17 to rotate relative to the mounting plate 11. When the telescopic transfer box 17 moves to the approximate gas escape area, it can flexibly adjust its angle according to the actual gas flow direction and escape angle, so that the collection port is more accurately aligned with the gas escape point, improving the efficiency and quality of gas collection. Even in narrow or complex underground engineering channels, the telescopic transfer box 17 can be rotated to avoid obstacles and get closer to the gas source for collection.

[0047] In this embodiment, the connecting shaft 13 can directly pass through the mounting plate 11 and the corresponding mounting parts of the telescopic transfer box 17. The friction during rotation can be reduced by bearings between the two, so that the telescopic transfer box 17 can rotate smoothly around the connecting shaft 13. Of course, an electric drive device can also be equipped to realize the rotation of the telescopic transfer box 17. The electric drive device can be a small motor, and the output shaft of the motor is connected to the connecting shaft 13. By controlling the forward and reverse rotation and the rotation angle of the motor, the direction of the telescopic transfer box 17 can be precisely adjusted.

[0048] Example 3

[0049] This embodiment 3 provides a device for collecting and emitting toxic and harmful gases, based on embodiment 1 or embodiment 2. Figures 1-4 As shown, to ensure the stability of the device's operation, a first support frame 3 and a second support frame 4 are fixedly connected to the lower surfaces of the first mounting box 5 and the second mounting box 7, respectively. The lower ends of the first support frame 3 and the second support frame 4 are in contact with the ground. These two support frames can distribute the weight of the transfer box, ensuring that it is stable and reliable during operation and preventing shaking or tipping. At the same time, a socket rod 12 is fixedly connected to the lower end of the second support frame 4, and a socket hole 18 is opened at the lower end of the first support frame 3. The end of the socket rod 12 away from the second support frame 4 is engaged with the socket hole 18. When the device is not in use or stored, the first support frame 3 and the second support frame 4 can be firmly connected, thereby enhancing the stability of the entire telescopic transfer box 17 in the stored state.

[0050] In some embodiments, a limiting frame 16 for isolation is provided between the air extraction mechanism 15 and the activated carbon filter box 14. The limiting frame 16 is fixedly connected to the right end of the first mounting box 5. When the device is not in use, the right surface of the limiting frame 16 contacts the left end of the second mounting box 7. The limiting frame 16 is used to prevent the activated carbon filter box 14 from contacting the right end of the air extraction mechanism 15.

[0051] In some embodiments, a flared connector 10 is provided on the left surface of the first installation box 5. The flared connector 10 is fixedly connected to the air inlet end of the suction mechanism 15. The flared connector 10 is trumpet-shaped, which increases the opening area of ​​the air inlet end of the suction mechanism 15. When collecting toxic and harmful gases, it can expand the suction range, so that the device can collect gases that escape from different angles and farther distances more efficiently, thereby improving the gas collection efficiency of the device.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
