Description

Technical Field

[0001] This utility model relates to the field of fog cannon tower technology, specifically to an anti-collision device for fog cannon towers. Background Technology

[0002] A collision avoidance device for fog cannon turrets is a mechanical protective component installed on the outside of the fog cannon turret (a rotatable or liftable column / frame structure supporting the fog cannon's launching body). Its core function is to buffer and disperse collision forces through structural design, preventing damage to the turret and core components due to collisions. It is typically arranged circumferentially around the turret and consists of an outer buffer structure that contacts the colliding object, an intermediate energy absorption component, and a fixing structure connected to the turret. In existing technologies, the rubber pads, single springs, and other structures of existing devices only form point or line contact with the colliding object. The impact force can only be transmitted unidirectionally along the normal direction of the contact point. There is a lack of guiding and diverting components to change the transmission path of the force, and it cannot diffuse in the circumferential or lateral direction. The single buffer structure can only absorb the impact force point-to-point and cannot transmit and disperse the force in all directions, which can easily lead to local stress concentration and deformation at the tower connection. If the compression of the rubber pad or ordinary spring is small, the buffering effect drops sharply when facing a large impact force, and it cannot effectively weaken the collision energy. Moreover, the exposed structure occupies a lot of transportation and storage space, which limits the flexibility of operation in narrow spaces. In addition, the components are prone to rust and entanglement, making maintenance inconvenient and also causing the risk of secondary collisions. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-collision device for fog cannon towers, so as to solve the problem that the single buffer structure proposed in the background art can only absorb the impact force point by point and cannot transmit and disperse the force to the surroundings, which easily leads to local stress concentration and causes deformation at the tower connection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-collision device for a fog cannon tower, comprising a tower base, protective rubber rods installed at both ends of the tower base, an adjustment component installed on the tower base, a multi-stage buffer component installed inside the tower base, a linkage component installed on the adjustment component, a flip-top component installed on the tower base, a rotating connecting seat installed on the adjustment component, an adjustment connecting frame fixedly connected to the rotating connecting seat, a fog cannon body installed on the adjustment connecting frame, a storage cover installed on the flip-top component, a guide connecting seat installed on the multi-stage buffer component, a buffer plate fixedly connected to the guide connecting seat, a rubber sleeve fixedly connected to the buffer plate, a rubber pad installed on the buffer plate, a sliding limit rod installed on the buffer plate, a first spring fixedly connected to one end of the sliding limit rod, and a first spring fixedly connected between the anti-collision plate and the buffer plate. The first spring is slidably connected inside the buffer plate. The first spring pushes the anti-collision plate to move in a preset direction, the multi-stage buffer component pushes the guide connecting seat to move in a preset direction, and the adjustment component drives the rotating connecting seat to move along the sliding groove direction inside the tower base.

[0005] Based on the preferred embodiment of this technical solution, a plurality of sliding limit rods are provided, and the plurality of sliding limit rods are arranged in an array on the rubber sheath.

[0006] Based on the preferred embodiment of this technical solution, both the buffer plate and the anti-collision plate are arc-shaped, and there are several anti-collision plates, which are arranged in an array on the front of the buffer plate.

[0007] According to the preferred embodiment of this technical solution, the multi-stage buffer assembly includes a sliding limiting sleeve slidably connected inside the tower base, a second spring fixedly connected between the guide connecting seat and the tower base, a sliding limiting ring fixedly connected to one end of the sliding limiting sleeve, a fixed limiting block fixedly connected to the sliding limiting ring, a fixed limiting rod fixedly connected to the tower base, and a third spring fixedly connected between the sliding limiting ring and the tower base. The sliding limiting sleeve is slidably connected to the fixed limiting rod, and the third spring pushes the sliding limiting ring to move along a preset direction.

[0008] In the preferred embodiment of this technical solution, two fixed limiting blocks are provided, and the two fixed limiting blocks are symmetrically fixedly connected to the sliding limiting ring.

[0009] According to the preferred embodiment of this technical solution, the adjustment component includes a drive motor mounted on the tower base, a rotating threaded rod fixedly connected to the output end of the drive motor, a sliding support seat threadedly connected to the rotating threaded rod, a fixed mounting rod fixedly connected inside the tower base, a limiting connecting block fixedly connected to the sliding support seat, and a storage groove opened inside the rotating support seat. The sliding support seat is slidably connected to the fixed mounting rod, and the drive motor drives the rotating threaded rod to rotate in a clockwise or counterclockwise direction.

[0010] Based on the preferred embodiment of this technical solution, the tower base has a limiting groove at the corresponding position of the limiting connecting block, and the limiting connecting block is slidably connected inside the limiting groove.

[0011] According to the preferred embodiment of this technical solution, the linkage component includes a first gear fixedly connected to the rotating threaded rod, a bevel gear rod rotatably connected inside the tower base, a first rotating rod rotatably connected inside the tower base, a fourth bevel gear fixedly connected to the first rotating rod, and a second bevel gear fixedly connected to the first rotating rod. The bevel gear rod is meshed with the first gear, and the bevel gear rod is meshed with the fourth bevel gear.

[0012] Based on the preferred embodiment of this technical solution, the flip cover assembly includes a fixed adjustment block installed on the tower base, a second rotating rod rotatably connected inside the fixed adjustment block, and a third bevel gear fixedly connected to the second rotating rod. The third bevel gear is meshed with the second bevel gear, and the actuation component drives the storage cover on the second rotating rod to rotate in a preset direction.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The combination of a rubber sleeve, rubber pad, and a first spring replaces the existing single rubber pad or spring, achieving both flexible contact and elastic energy absorption, avoiding unidirectional transmission of impact force. Secondly, several arrayed sliding limit rods form multi-path force transmission channels, evenly distributing the force borne by the anti-collision plate to the buffer plate, preventing overload of a single component. Finally, the arc-shaped design of the buffer plate and the arrayed anti-collision plates significantly increase the contact area, transforming point or line contact into multi-point surface contact. Combined with the guiding and diverting effect of the sliding limit rods, this allows the impact force to diffuse circumferentially and laterally. These three elements work synergistically, optimizing the contact form, force transmission path, and dispersion method from all angles, completely resolving the stress concentration problem of existing devices, significantly reducing the risk of deformation at the tower base connection, and improving protection reliability and service life.

[0014] 2. The second and third springs form a progressive energy absorption mechanism, breaking through the compression limitations of a single spring and extending the overall buffer stroke. This allows for continuous energy absorption even under significant impact, preventing sudden loss of buffering effectiveness. Secondly, the cooperation between the sliding limit sleeve and the fixed limit rod provides precise guidance for the buffering movement, ensuring that the spring deformation always follows a preset direction and preventing a decrease in energy absorption efficiency due to force deviation. Furthermore, two symmetrically distributed fixed limit blocks ensure the smooth movement of the sliding limit ring, preventing component jamming and improving structural reliability. This component, through the synergistic design of "elastic energy absorption + guiding limit," solves the problem of insufficient energy absorption in a single buffer structure and ensures stable and controllable buffering through mechanical constraints. It effectively weakens impact forces of varying intensities, significantly reducing the risk of damage to the tower base due to overload impacts, and is suitable for the protection needs of complex operation scenarios for fog cannons.

[0015] 3. The adjustment component, through the cooperation of a drive motor and a rotating threaded rod, smoothly moves the rotating connecting seat, allowing the fog cannon body and buffer component to be stored inside the tower base, significantly reducing the space occupied during transportation and storage and improving space utilization. Secondly, the linkage component, through gear meshing, enables the adjustment component and the flip-top component to move synchronously, achieving precise synchronization of buffer component unfolding and storage cover opening, and buffer component retraction and storage cover closing without an additional power source, simplifying the operation process. Furthermore, the closed storage cover effectively protects the internal components, preventing corrosion and damage from snagging during transportation and storage, while the unfolded state does not affect the protective function, adapting to the needs of operating in confined spaces. These three aspects work together to solve the storage problems of existing devices, improve operational convenience and component protection, balance practicality and adaptability, and significantly broaden the application scenarios of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model provides an embodiment of an anti-collision device for a fog cannon tower: It includes a tower base 1, protective rubber rods 2 installed at both ends of the tower base 1, an adjustment assembly installed on the tower base 1, a multi-stage buffer assembly installed inside the tower base 1, a linkage assembly installed on the adjustment assembly, a flip-top assembly installed on the tower base 1, a rotating connecting seat 3 installed on the adjustment assembly, an adjustment connecting frame 4 fixedly connected to the rotating connecting seat 3, a fog cannon body 5 installed on the adjustment connecting frame 4, a storage cover 6 installed on the flip-top assembly, a guide connecting seat 701 installed on the multi-stage buffer assembly, and a component fixedly connected to the guide connecting seat 701. The buffer plate 702, the rubber sleeve 703 fixedly connected to the buffer plate 702, the rubber pad 704 installed on the buffer plate 702, the sliding limit rod 705 installed on the buffer plate 702, the first spring 706 fixedly connected to one end of the sliding limit rod 705 and the first spring 706 fixedly connected between the anti-collision plate 707 and the buffer plate 702, the first spring 706 slidably connected inside the buffer plate 702, the first spring 706 pushes the anti-collision plate 707 to move in a preset direction, the multi-stage buffer assembly pushes the guide connecting seat 701 to move in a preset direction, and the adjusting assembly drives the rotating connecting seat 3 to move in the direction of the internal sliding groove of the tower base 1. By combining the rubber sleeve 703, the rubber pad 704 and the first spring 706, the initial impact force of the collision is weakened by flexible contact, and the elastic deformation of the first spring 706 is used to further absorb energy. At the same time, the sliding limit rod 705 precisely constrains the movement direction of the anti-collision plate 707, so as to avoid the anti-collision plate 707 from deviating during the collision and causing the protection to fail. This effectively disperses the local stress of the tower base 1 and reduces the risk of deformation at the connection of the tower base 1.

[0020] Please see Figure 2-3A further solution based on this embodiment is as follows: A plurality of sliding limit rods 705 are provided, and these sliding limit rods 705 are arranged in an array on the rubber sleeve 703. By arranging the plurality of sliding limit rods 705 in an array on the rubber sleeve 703, the impact force received by the anti-collision plate 707 can be evenly transmitted to each sliding limit rod 705, and then distributed to the entire buffer plate 702 through the sliding limit rods 705. This avoids the breakage of a single sliding limit rod 705 due to overload. At the same time, the array distribution structure ensures that the anti-collision plate 707 remains stable during movement, improving the force balance and service life of the buffer structure composed of the buffer plate 702 and the anti-collision plate 707.

[0021] Please see Figure 2-3 A further solution based on this embodiment is as follows: both the buffer plate 702 and the anti-collision plate 707 are arc-shaped, and several anti-collision plates 707 are provided, with the several anti-collision plates 707 arranged in an array on the front of the buffer plate 702. By designing the buffer plate 702 and the anti-collision plate 707 as arc-shaped, the contact area with the colliding object is increased, avoiding point-to-point stress concentration. At the same time, the several arrayed anti-collision plates 707 can achieve multi-contact synchronous buffering, allowing the collision force to be transmitted to the buffer plate 702 from multiple contact points, further improving the force dispersion effect, adapting to collision scenarios at different angles, and expanding the protective coverage of the device.

[0022] Please see Figure 4 A further solution based on this embodiment is as follows: the multi-level buffer assembly includes a sliding limiting sleeve 801 slidably connected inside the tower base 1, a second spring 802 fixedly connected between the guide connecting seat 701 and the tower base 1, a sliding limiting ring 803 fixedly connected to one end of the sliding limiting sleeve 801, a fixed limiting block 804 fixedly connected to the sliding limiting ring 803, a fixed limiting rod 805 fixedly connected to the tower base 1, and a third spring 806 fixedly connected between the sliding limiting ring 803 and the tower base 1. The sliding limiting sleeve 801 is slidably connected to the fixed limiting rod 805, and the third spring 806 pushes the sliding limiting ring 803 to move along a preset direction. Through the linkage design of the second spring 802, the third spring 806, the sliding limit sleeve 801, and the fixed limit rod 805, a multi-stage buffer stroke is formed. When the outer buffer plate 702, the anti-collision plate 707 and other buffer structures are compressed to their limit, the second spring 802 first absorbs energy, and then the sliding limit sleeve 801 slides along the fixed limit rod 805, driving the third spring 806 to continuously deform and absorb energy, effectively extending the overall buffer stroke, solving the problem of a sudden drop in buffer effect caused by insufficient compression of a single spring, and greatly reducing the impact of large impact forces on the tower base 1.

[0023] Please see Figure 4A further solution based on this embodiment is as follows: two fixed limiting blocks 804 are provided, and the two fixed limiting blocks 804 are symmetrically fixedly connected to the sliding limiting ring 803. Through the two symmetrically distributed fixed limiting blocks 804, the movement trajectory of the sliding limiting ring 803 is bidirectionally constrained, preventing the sliding limiting ring 803 from deviating or tilting during sliding, ensuring that the third spring 806 can deform stably along the preset direction. At the same time, the symmetrical structure can make the forces at both ends of the sliding limiting ring 803 balanced, preventing the sliding limiting sleeve 801 from jamming with the fixed limiting rod 805 due to excessive force on one side, thereby improving the stability and reliability of the multi-stage buffer assembly.

[0024] Please see Figure 5-6 A further solution based on this embodiment is as follows: the adjustment component includes a drive motor 902 mounted on the tower base 1, a rotating threaded rod 903 fixedly connected to the output end of the drive motor 902, a sliding support 904 threadedly connected to the rotating threaded rod 903, a fixed mounting rod 905 fixedly connected inside the tower base 1, a limiting connecting block 906 fixedly connected to the sliding support 904, and a storage groove 901 opened inside the rotating connection 3. The sliding support 904 is slidably connected to the fixed mounting rod 905, and the drive motor 902 drives the rotating threaded rod 903 to rotate in a clockwise or counterclockwise direction. The drive motor 902 drives the rotating threaded rod 903 to rotate, which in turn drives the sliding support 904 to move smoothly along the fixed mounting rod 905, thereby realizing the position adjustment of the rotating connecting seat 3. With the storage groove 901 inside the rotating connecting seat 3, the fog cannon body 5 or buffer components such as the buffer plate 702 and the anti-collision plate 707 can be stored inside the tower base 1, reducing the space occupied during transportation and storage. At the same time, the limiting connecting block 906 cooperates with the limiting groove of the tower base 1 to ensure the precise movement of the sliding support 904 and avoid structural displacement during the adjustment process.

[0025] Please see Figure 5-6 A further solution based on this embodiment is as follows: a limiting groove is formed at the corresponding position of the limiting connecting block 906 on the tower base 1, and the limiting connecting block 906 is slidably connected inside the limiting groove. Through the sliding engagement between the limiting connecting block 906 and the limiting groove on the tower base 1, the movement range of the sliding support 904 is precisely limited, preventing the sliding support 904 from exceeding the preset stroke due to over-driving by the drive motor 902, and avoiding collision damage between the sliding support 904 and the tower base 1 or the rotating connecting seat 3. At the same time, the limiting groove can guide the limiting connecting block 906 to move along a fixed trajectory, further improving the stability of the adjustment component operation and ensuring smooth and reliable storage and unfolding processes.

[0026] Please see Figure 5-6A further solution based on this embodiment is as follows: The linkage component includes a first gear 907 fixedly connected to the rotating threaded rod 903, a bevel gear rod 908 rotatably connected inside the tower base 1, a first rotating rod 909 rotatably connected inside the tower base 1, a fourth bevel gear 914 fixedly connected to the first rotating rod 909, and a second bevel gear 910 fixedly connected to the first rotating rod 909. The bevel gear rod 908 is meshed with the first gear 907, and the bevel gear rod 908 is meshed with the fourth bevel gear 914. Through the meshing transmission of the first gear 907, the bevel gear rod 908, the fourth bevel gear 914, and the second bevel gear 910, the linkage control of the adjustment component and the flip-top component is realized. The buffer components such as the buffer plate 702 can be synchronously stored or unfolded and the storage cover 6 can be opened and closed without an additional power source, simplifying the operation process. At the same time, the gear meshing transmission method has high transmission efficiency and strong stability, ensuring precise and synchronous switching between storage and protection states, and improving the ease of use of the device.

[0027] Please see Figure 5-6 A further solution based on this embodiment is as follows: The flip-top assembly includes a fixed adjustment block 911 mounted on the tower base 1, a second rotating rod 912 rotatably connected inside the fixed adjustment block 911, and a third bevel gear 913 fixedly connected to the second rotating rod 912. The third bevel gear 913 is meshed with the second bevel gear 910. The actuating component drives the storage cover 6 on the second rotating rod 912 to rotate in a preset direction. Through the meshing of the third bevel gear 913 and the second bevel gear 910, the rotational motion of the first rotating rod 909 is converted into the rotation of the second rotating rod 912, thereby driving the storage cover 6 to open and close in a preset direction. When the device is in the storage state, the closed storage cover 6 can protect the internal buffer plate 702, anti-collision plate 707 and other buffer components and the fog cannon body 5, preventing parts from rusting or being snagged by foreign objects during transportation and storage. When the device is deployed for operation, the open storage cover 6 does not affect the protective function, taking into account both protection and adaptability.

[0028] The drive motor 902 in the adjustment assembly can also be replaced by a manual crank mechanism or a cylinder drive mechanism, both existing technologies. The manual crank mechanism engages with a rotating threaded rod 903 via gears, while the cylinder drive mechanism is fixedly connected to a sliding support 904 via a piston rod. The advantages are: the manual crank mechanism requires no external power supply, making it suitable for scenarios without power, thus reducing operating costs; the cylinder drive mechanism offers faster response, enabling rapid storage and deployment of the buffer assembly, meeting the needs of high-frequency switching operations. Both replacement structures are simple in structure and easy to operate, meeting the needs of university students in writing and implementing these solutions.

[0029] The first spring 706, the second spring 802, and the third spring 806 in the multi-stage buffer assembly can also be replaced by disc springs and elastic rubber pillars from existing technologies. The disc springs are stacked and installed on the outside of the sliding limit rod 705, and the elastic rubber pillars are embedded and fixed between the guide connecting seat 701 and the tower base 1. The advantages are: the disc springs have a stronger load-bearing capacity and excellent fatigue resistance, making them suitable for long-term high-frequency collision scenarios; the elastic rubber pillars have a silent buffering effect, reducing mechanical noise during collisions, and are easier to install and disassemble. Neither of the two replacement structures requires changing the original installation layout, and they have strong compatibility.

[0030] Working principle: The drive motor 902 drives the rotating threaded rod 903 to rotate, causing the sliding support 904 to move along the fixed mounting rod 905, pushing the fog cannon body 5 on the rotating connecting seat 3 and the adjusting connecting frame 4 to extend out of the tower base 1; at the same time, the linkage component, through the first gear 907 meshing with the bevel gear rod 908, drives the first rotating rod 909 to rotate via the fourth bevel gear 914, and the second bevel gear 910 meshing with the third bevel gear 913 to rotate the second rotating rod 912, opening the storage cover 6 and exposing the multi-stage buffer assembly. When a collision occurs, the rubber sleeve 703 and the rubber pad 704 first contact the colliding object, weakening the initial impact force through flexible deformation; after being subjected to force, the anti-collision plate 707 compresses the first spring 70. 6. The sliding limit rod 705 guides the anti-collision plate 707 to move smoothly, dispersing the force to the buffer plate 702; the impact force is transmitted to the guide connecting seat 701, compressing the second spring 802 to further absorb energy; if the impact force is large, the sliding limit sleeve 801 slides along the fixed limit rod 805, driving the sliding limit ring 803 to compress the third spring 806, forming a multi-stage buffer. The fixed limit block 804 ensures the stability of the buffer direction and avoids stress concentration. When storing, the sliding support seat 904 drives the rotating connecting seat 3 to retract, and the fog cannon body 5 and the buffer assembly enter the storage slot 901; the linkage component synchronously drives the storage cover 6 to close, and the protective rubber rod 2 assists in protecting both ends of the tower base 1, achieving space saving and component protection. The entire process is linked by a mechanical structure, requiring no complex control and adaptable to various operating scenarios.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
