Description

Technical Field

[0001] This application relates to the field of aerogel felt laying technology, and particularly to an automatic aerogel felt laying equipment. Background Technology

[0002] With the widespread application of hazardous chemicals in industrial transportation, chemical storage, and energy supply, emergency response to leaks in accident situations has become a key technological direction for public safety and disaster prevention. Liquid hazardous chemicals generally possess high volatility and flammability / explosiveness. Once leaked and spread to the ground, they rapidly evaporate, forming flammable vapor clouds that can easily reach their explosive limits in confined spaces or poorly ventilated environments, triggering secondary disasters such as fires and explosions, seriously threatening personnel safety and facility integrity. Currently, conventional leak control methods mainly include foam spraying, manual absorption, or covering with fireproof cloth. However, these traditional methods have significant limitations: long response times, reliance on close-range manual operation, poor coverage continuity, and limited material insulation performance. Especially in accident scenarios such as high temperatures, high wind speeds, uneven ground, or complex confined spaces, it is difficult to form a durable, uniform liquid surface covering with good thermal insulation and flame retardant effects, severely impacting emergency response efficiency and safety.

[0003] Flexible aerogel felt, as an emerging nanoporous thermal insulation material, is considered to have significant application potential in the field of covering hazardous chemical spills due to its extremely low thermal conductivity (typically below 0.02 W / m·K), excellent flexibility, and good chemical stability.

[0004] However, the application of aerogel felt at actual leak sites still faces a significant challenge: the lack of automated, rapid, and safe dedicated laying equipment that matches its physical properties. Existing laying methods mostly rely on manual handling, spreading, and fixing, which is not only slow to respond and high-risk, but also makes it difficult to achieve continuous, uniform, large-area coverage, limiting the material's actual effectiveness in emergencies. Furthermore, conventional laying devices for materials such as fabrics and films are generally not suitable for functional materials like aerogel felt, which are somewhat brittle, easily bent, and require structural integrity. This can easily lead to material damage or folding failure during transport and deployment, affecting the covering effect.

[0005] In view of this, there is an urgent need to provide an automated aerogel mat laying equipment that can improve user safety while enhancing the coverage of leaked hazardous chemicals. Summary of the Invention

[0006] This application is made in view of the aforementioned state of the prior art. The purpose of this application is to provide an automated aerogel mat laying device that can improve the covering effect of leaked hazardous chemicals.

[0007] An automated aerogel felt laying device is provided, comprising a frame, a drive wheel assembly, a roll-mounting shaft, aerogel felt, a vehicle drive unit, a roll-release mechanism, and a control component. The drive wheel assembly, vehicle drive unit, and roll-release mechanism are mounted to the frame. The drive wheel assembly is located at the bottom of the frame and is driven to rotate by the vehicle drive unit. The drive wheel assembly consists of Mecanum wheels to move the automated aerogel felt laying device in both the front-to-back and left-to-right directions. The aerogel felt is wound around the roll-mounting shaft, which is connected to the frame. The axis of the roll-mounting shaft is parallel to the left-to-right direction. The roll-release mechanism drives the roll-mounting shaft to rotate, releasing the aerogel felt as the shaft rotates. The vehicle drive unit and roll-release mechanism are connected to the control component, which controls the coordinated operation of the vehicle drive unit and the roll-release mechanism.

[0008] In at least one embodiment, the control unit controls the vehicle drive and the roll release mechanism such that the automatic aerogel felt laying equipment moves at the same speed in the front-rear direction as the aerogel felt is released.

[0009] In at least one embodiment, the automatic aerogel mat laying equipment includes a plurality of Mecanum wheels, and the vehicle drive includes a drive motor individually configured for each Mecanum wheel, so that each Mecanum wheel can move independently.

[0010] In at least one embodiment, a U-shaped mounting shaft bracket is provided on the top of the frame, and the roll mounting shaft is detachably connected to the U-shaped mounting shaft bracket.

[0011] In at least one embodiment, the opening of the U-shaped mounting shaft bracket is provided with a locking element, which is rotatable between a first position and a second position. When the locking element is in the first position, the opening of the U-shaped mounting shaft bracket is closed, and when the locking element is in the second position, the opening of the U-shaped mounting shaft bracket is open.

[0012] In at least one embodiment, the U-shaped mounting shaft bracket is provided with a groove, and the roll mounting shaft is provided with limiting protrusions at both ends in the left-right direction. When the roll mounting shaft is installed on the U-shaped mounting shaft bracket, the limiting protrusions are embedded in the groove to limit the roll mounting shaft in the left-right direction of the automatic gel felt laying equipment.

[0013] In at least one embodiment, the limiting protrusion is a rolling bearing to reduce the frictional force of the roll mounting shaft during rotation.

[0014] In at least one embodiment, the roll release mechanism includes a roll release motor, which drives the roll mounting shaft to rotate via a gear set.

[0015] In at least one embodiment, the automatic aerogel felt laying equipment further includes an explosion-proof box, and the electrical components of the automatic aerogel felt laying equipment are disposed in the explosion-proof box.

[0016] In at least one embodiment, the frame is a frame structure made of profiles, and the aerogel felt extends into the frame structure.

[0017] The automatic aerogel felt laying equipment provided above, through the solution of this application embodiment, by setting a vehicle drive device and the roll release mechanism connected to the control component, can control the vehicle drive device and the roll release mechanism to work together, which can avoid the aerogel felt being released too fast or too slow, causing accumulation, dragging and other phenomena. It can also avoid the problem of poor coverage caused by material wrinkles, tears or failure to adhere flatly to the ground during the release process, and can improve the coverage effect of leaked hazardous chemicals.

[0043] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0044] The embodiments of this application relate to an automatic aerogel felt laying equipment. The aforementioned aerogel felt can be a felt structure formed by combining aerogel with composite fiber felt (such as glass fiber or ceramic fiber), wherein the aerogel is the core heat insulation filler, and the composite fiber felt is the reinforcing support skeleton. It should be understood that aerogel felt has certain flexibility, brittleness, and easy curling.

[0045] like Figures 1 to 5 As shown, the automated aerogel felt laying equipment may include a frame 10, a drive wheel assembly, a roll mounting shaft 30, an aerogel felt 40, a vehicle drive unit, a roll release mechanism, and control components. The aforementioned drive wheel assembly, vehicle drive unit, and roll release mechanism are mounted to the frame 10.

[0046] like Figure 2a and Figure 4As shown, the frame 10 may include a first support rod 11, a second support rod 12, a third support rod 13, and a fourth support rod 14. The first support rod 11 and the second support rod 12 may be parallel to the left-right direction LR, and the third support rod 13 and the fourth support rod 14 may be parallel to the front-back direction FR.

[0047] like Figure 2a and Figure 4 As shown, an aerogel felt receiving space 101 can be formed between the first support rod 11, the second support rod 12, the third support rod 13, and the fourth support rod 14, and the aerogel felt 40 can be partially placed within this aerogel felt receiving space 101. This reduces the height of the aerogel felt 40, making it easier to lay.

[0048] Furthermore, such as Figure 2a As shown, the aforementioned first support rod 11 can be fixedly connected to the third support rod 13 and the fourth support rod 14 respectively, and the second support rod 12 can be fixedly connected to the third support rod 13 and the fourth support rod 14 respectively.

[0049] The drive wheel set is located at the bottom of the frame 10 and is driven to rotate by the vehicle drive unit. The drive wheel set is a Mecanum wheel 20, which drives the automatic aerogel felt laying equipment to move in the front-rear direction FR and the left-right direction LR of the automatic aerogel felt laying equipment.

[0050] Optionally, the automated aerogel mat laying equipment may include multiple Mecanum wheels 20. Furthermore, the vehicle drive may include a separate drive motor 51 for each Mecanum wheel 20, allowing each Mecanum wheel 20 to move independently.

[0051] It is understandable that, such as Figure 1 , Figure 2a and Figure 4 As shown, there can be four Mecanum wheels 20, symmetrically arranged at the four corners of the frame 10. Specifically, in the front-rear direction (FR), one Mecanum wheel 20 can be provided at each end (i.e., the front and rear ends) of the third support rod 13, and one Mecanum wheel 20 can be provided at each end (i.e., the front and rear ends) of the fourth support rod 14.

[0052] It should be understood that the positions and orientations of the Mecanum wheels 20 in this application (e.g., the roller orientation of each Mecanum wheel 20) are merely illustrative and not restrictive, and can be adjusted as needed (e.g., in the front-rear direction FR, the two Mecanum wheels 20 at both ends of the third support rod 13 can be symmetrically arranged, and the two Mecanum wheels 20 at both ends of the fourth support rod 14 can be symmetrically arranged. In the left-right direction LF, the two Mecanum wheels 20 located on both sides of the first support rod 11 can be symmetrically arranged, and the two Mecanum wheels 20 located on both sides of the second support rod 12 can be symmetrically arranged).

[0053] It is understandable that the drive motor 51 can be a servo motor. Furthermore, the drive motor 51 can be located at the bottom of the frame 10. For example... Figure 2a As shown, multiple drive motors 51 can be installed at the bottom of the third support rod 13 and the bottom of the fourth support rod 14.

[0054] Each drive motor 51 can drive one Mecanum wheel. It can be understood that by setting each motor to independently drive one Mecanum wheel (i.e., the speed and direction of rotation of the Mecanum wheel can be individually controlled by the drive motor 51), it is possible to achieve rotation in the forward / backward (FR) and left / right (LR) planes (see...). Figure 4 The device has functions such as forward, backward, lateral, diagonal, and in-situ rotation (as shown in the plane), which can improve the deployment flexibility of the automatic aerogel felt laying equipment in narrow, obstacle-filled, or irregular sites.

[0055] Aerogel felt 40 is wound around a roll mounting shaft 30, which is connected to the frame 10. The axis of the roll mounting shaft 30 is parallel to the left-right direction LR.

[0056] It is understandable that when the roll mounting shaft 30 rotates, the aerogel felt 40 can rotate with the roll mounting shaft, thereby enabling the release of the aerogel felt 40.

[0057] The roll release mechanism drives the roll mounting shaft 30 to rotate, and the aerogel felt 40 can be released as the roll mounting shaft 30 rotates.

[0058] Optionally, such as Figure 2a and Figure 4 As shown, the roll release mechanism may include a roll release motor 61, which drives the roll mounting shaft 30 to rotate via a gear set 62.

[0059] Specifically, such as Figure 2aAs shown, the gear set 62 may include a roll release gear 621 and a roll mounting shaft gear 622. The aforementioned roll release gear 621 can be connected to the output shaft of the roll release motor 61. The roll mounting shaft gear 622 is connected to the roll mounting shaft 30, and the roll release gear 621 and the roll mounting shaft gear 622 are meshed and connected for transmission. When the output shaft of the roll release motor 61 rotates, the roll mounting shaft 30 can be driven to rotate through the roll release gear 621 and the roll mounting shaft gear 622, thereby realizing the release of the aerogel felt 40.

[0060] Furthermore, the vehicle drive unit and the roll release mechanism are connected to the control unit, which controls the vehicle drive unit and the roll release mechanism to work together.

[0061] Optionally, when the roll material needs to be released, the control unit controls the vehicle drive and the roll material release mechanism so that the speed of the automatic aerogel felt laying equipment in the forward and backward direction FR is the same as the release speed of the aerogel felt 40 (i.e., the linear speed of the released aerogel felt sheet).

[0062] It is important to understand that within the plane formed by the forward / backward direction (FR) and the vertical direction (H) (see...) Figure 5 The cross-section of the aerogel felt 40 (as shown in the plane) can be circular, and the aerogel felt 40 has a first radial direction R1. The cross-section of the Mecanum wheel 20 is circular, and the Mecanum wheel 20 has a second radial direction R2.

[0063] When the automatic aerogel felt laying equipment is in operation, the linear velocity of the outermost part of the aerogel felt 40 in its first radial direction R1 can be the same as the linear velocity of the Mecanum wheel 20 at its outermost end in its second radial direction R2, so that the movement speed of the automatic aerogel felt laying equipment in the front-to-back direction FR is the same as the release speed of the aerogel felt 40.

[0064] It is important to understand that by setting the automatic aerogel felt laying equipment to move at the same speed as the aerogel felt 40 in the forward and backward direction FR, it is possible to avoid the aerogel felt being released too quickly or too slowly, which could cause accumulation or dragging. This can prevent problems such as material wrinkles, tears, or failure to adhere smoothly to the ground during the release process, resulting in poor coverage and improving the coverage of leaked hazardous chemicals.

[0065] It should be understood that the automatic aerogel mat laying equipment can be manually controlled to move, and the control components can control the release speed of the aerogel mat 40 according to the movement of the automatic aerogel mat laying equipment.

[0066] Furthermore, the aforementioned control components may include an on-board controller and a remote controller.

[0067] The aforementioned remote controller may include terminals such as mobile phones, computers, and tablets. The remote controller can be connected to the vehicle-mounted controller via a communication module. The aforementioned vehicle-mounted controller can be installed on the vehicle frame 10, and the vehicle-mounted controller can control the rotation of the drive motor 51 and the roll release motor 61.

[0068] By setting up control components, users can remotely operate the automatic aerogel felt laying equipment, avoiding close contact between personnel and high-risk leakage areas, effectively reducing personal safety risks during operations.

[0069] Optionally, such as Figure 2a and Figure 2b As shown, a U-shaped mounting shaft bracket 31 is provided on the top of the frame 10, and the roll mounting shaft 30 is detachably connected to the U-shaped mounting shaft bracket 31.

[0070] like Figure 5 As shown, the opening of the U-shaped mounting shaft bracket 31 can face upwards in the height direction H. The roll material mounting shaft 30 can extend into the U-shaped mounting shaft bracket 31 along the aforementioned opening to achieve the installation of the roll material mounting shaft 30 and the U-shaped mounting shaft bracket 31. It should be understood that the aforementioned roll material mounting shaft 30 and U-shaped mounting shaft bracket 31 are quick-release structures.

[0071] It is understandable that, such as Figure 2a and Figure 2b As shown, by setting the roll mounting shaft 30 and the U-shaped mounting shaft bracket 31 to be detachable, when the aerogel felt on the roll mounting shaft 30 is used up or needs to be replaced with aerogel felt of different sizes (different axial lengths / widths), the aerogel felt can be replaced during the working interval, which is convenient for replenishment and can adapt to the needs of different leakage areas.

[0072] like Figure 5 As shown, optionally, the opening of the U-shaped mounting shaft bracket 31 is provided with a locking member 311, which can rotate between a first position and a second position. When the locking member 311 is in the second position, the opening of the U-shaped mounting shaft bracket 31 is open, and when the locking member 311 is in the first position, the opening of the U-shaped mounting shaft bracket 31 is closed.

[0073] It is understood that the locking element 311 can be a knife gate, which is rotatably connected to the U-shaped mounting shaft bracket 31. Specifically, the locking element 311 can be rotatably connected to the U-shaped mounting shaft bracket 31 via a rotating shaft.

[0074] Optionally, such as Figure 2a and Figure 2b As shown, the U-shaped mounting shaft bracket 31 is provided with a groove 312, and the roll mounting shaft 30 is provided with limit protrusions 313 at both ends in the left-right direction LR.

[0075] When the roll mounting shaft 30 is installed on the U-shaped mounting shaft bracket 31, the limiting protrusion 313 is embedded in the groove 312, thereby limiting the roll mounting shaft 30 in the left-right direction LR of the automatic gel felt laying equipment.

[0076] Optionally, the limiting protrusion 313 is a rolling bearing to reduce the friction of the roll mounting shaft 30 during rotation.

[0077] It is understood that the aforementioned roll mounting shaft 30 can be connected to the inner ring of the rolling bearing. In the left-right direction LR, the outer ring of the rolling bearing can abut against the groove 312, thereby limiting the left-right direction LR of the roll mounting shaft 30. When the roll mounting shaft 30 rotates, the inner ring of the rolling bearing can rotate with the roll mounting shaft 30.

[0078] By using rolling bearings, the frictional force of the roll mounting shaft 30 when rotating relative to the U-shaped mounting shaft bracket 31 can be reduced.

[0079] Optionally, the automated aerogel mat laying equipment also includes an explosion-proof enclosure, in which the electrical components of the automated aerogel mat laying equipment are housed. The explosion-proof enclosure has an explosion-proof rating of IP65 or higher.

[0080] It should be understood that the electrical components in this application can be powered by a low-voltage (e.g., 24V or 48V) DC power supply system.

[0081] Optionally, the frame 10 is a frame structure made of profiles, with aerogel felt extending into the frame structure.

[0082] It should be understood that the automatic aerogel felt laying equipment may also include a compaction component (not shown in the figure), which may be a roller in the front-rear direction FR, and the roller may be located on one side of the release roll of the automatic aerogel felt laying equipment.

[0083] After the automatic aerogel mat deployment equipment releases the aerogel mat 40, the released aerogel mat 40 will (under the influence of gravity) fall onto or is about to fall onto the target area (the location where chemicals have been leaked). The aforementioned rollers can rotate and compress the aerogel mat 40 that has fallen onto or is about to fall onto the target area, so that the aerogel mat 40 can adhere to and cover the target area, thereby improving the effect of suppressing the volatilization of chemicals leaked on the target area and improving wind resistance.

[0084] It should be understood that at least some aspects or features of the above-described implementation methods, embodiments, or examples can be appropriately combined.

[0085] It is understood that, in this application, when the number of parts or components is not specifically limited, the number can be one or more, where multiple refers to two or more. For cases where the number of parts or components shown in the drawings and / or described in the specification is, for example, two, three, four, etc., this specific number is generally exemplary and not restrictive, and can be understood as multiple, i.e., two or more; however, this does not mean that this application excludes the case of one.
