Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to a quick-connect fire extinguishing bomb. Background Technology

[0002] In situations requiring firefighting, such as forests, grasslands, high-rise buildings, and large chemical industrial parks, remote deployment of fire extinguishing bombs can reduce casualties in high-risk scenarios. However, traditional connection and installation methods involve precise operations such as mechanical alignment and circuit matching. These methods are prone to errors in a panic and are difficult for non-professionals to operate successfully in harsh environments such as high altitudes and high temperatures, hindering firefighting efficiency. Repeated adjustments delay the deployment time, causing the best opportunity to control the fire to be missed.

[0003] Moreover, during the long-distance deployment process, the bumps and vibrations can easily loosen the connection of the fire extinguishing bomb. If the fire extinguishing bomb falls off during deployment, it will directly affect the fire extinguishing plan. Although the existing simple quick-connect interface can shorten the installation time of the fire extinguishing bomb, the locking strength is insufficient and cannot withstand the impact of long-distance deployment.

[0004] Therefore, a new technical solution is needed to address the problems existing in the current technology. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 and Figure 3 As shown, a quick-connect fire extinguishing grenade includes a grenade body 1, a control valve assembly 2, and a quick-connect assembly. The control valve assembly 2 is detachably connected to the grenade body 1. Through the structure of quick assembly and disassembly, the quick-connect fire extinguishing grenade can flexibly replace the grenade body 1 with different capacities and different types of fire extinguishing agents according to the fire situation requirements, and is suitable for complex fire situations that require rapid response.

[0020] like Figure 3 As shown, the control valve assembly 2 includes a connecting part 21, a control device 22, and a switching valve 23 fixedly connected to the control device 22.

The communication part supports remotely receiving control signals to control the opening and closing of the switching valve 23, avoiding close contact between personnel and the fire and improving the safety of firefighting operations.

[0021] like Figures 2-4As shown, the quick-connect assembly is pre-installed on the vehicle. The quick-connect assembly is slidably connected to the connecting part 21. The control valve assembly 2 containing the projectile 1 is quickly aligned and connected to the quick-connect assembly through the slide groove 3113, which reduces the installation difficulty of the fire extinguishing projectile and improves the assembly efficiency. The quick-connect assembly includes a quick-connect housing 31 and a switch 32. The quick-connect housing 31 includes a clamping part 311, a connecting plate 312 and a wire harness connection end 313. The connecting plate 312 is detachably connected to the clamping part 311, and the wire harness connection end 313 is fixedly connected to the clamping part 311. The clamping part 311 has a slide groove 3113 at one end away from the connecting plate 312. The connecting part 21 is installed on the clamping part 311 through the slide groove 3113. The wire harness connection end 313 has at least one wire harness through port 3131. One end of the communication wire harness is connected to the wire harness connection port 25, and the other end passes through the wire harness through port 3131, thereby reducing the communication wire harness tangling and direct friction.

[0022] like Figures 5-7 As shown, the switch 32 includes a switch locking member 321 and a switch external control 322 fixed relative to the switch locking member 321. When the switch external control 322 is in the closed state, the switch locking member 321 is engaged with the connecting part 21. A locking member 3231 is fixedly connected to one end of the switch external control 322 located outside the quick-connect housing 31, near the outer side wall of the quick-connect housing 31. A switch slot 3112 is provided on the outer side wall of the clamping part 311. The locking member 3231 is embedded in the switch slot 3112 to restrict the rotation of the switch external control 322. The locking member 3231 can prevent the switch external control 322 from rotating accidentally due to vibration, thus ensuring the locking stability of the switch 32. When it is necessary to switch to the open state, the switch 32 is pulled out radially to a shorter length, and the locking member 3231 is disengaged from the slot, realizing quick unlocking, thereby balancing safety and ease of operation.

[0023] like Figures 3-9As shown, the switch locking member 321 includes a rotating section 3211 and a snap-fit ​​end 3212 that are fixedly connected to each other. The rotating section 3211 has a recessed section 3201 at one end near the snap-fit ​​end 3212. The end of the switch external control 322 near the rotating section 3211 and the end of the rotating section 3211 away from the snap-fit ​​end 3212 have a contact surface that abuts against each other. The connecting part 21 has a rotating groove 211. The snap-fit ​​end 3212, projected axially along the rotating section 3211, is at least partially located on the inner wall of the clamping part 311 outside the rotating groove 211. The rotating groove 211 further strengthens the connection between the connecting part 21 and the clamping part 311, preventing the control valve assembly 2 from separating from the quick-connect assembly. The switch locking member 321 restricts the control valve assembly 2 from displacing along the length of the slide groove 3113 during remote deployment, ensuring a stable connection. Qualitatively, the clamping part 311 has a switch mounting hole 3111, the rotating section 3211 and the connection between the rotating section 3211 and the external control 322 of the switch are located inside the switch mounting hole 3111. The diameter of the external control 322 of the switch is equal to the outer diameter of the switch mounting hole 3111, ensuring that the switch 32 can rotate stably without sliding out radially, avoiding the control valve assembly 2 from separating from the quick-connect assembly due to the loosening of the switch 32, and ensuring that the switch state can be switched stably. When the switch 32 is in the open state, the upper end of the concave section 3201 is lower than the lowest end of the rotating groove 211, and the control valve assembly 2 and the quick-connect assembly can slide relative to each other along the slide groove 3113. When the switch 32 is in the closed state, the concave section 3201 is located in the rotating groove 211, and the switch 32 connects and locks the control valve assembly 2 and the quick-connect assembly.

[0024] like Figures 1-9As shown, in at least one embodiment, the projectile 1 is a dry powder fire extinguishing projectile, the connecting part 21 is T-shaped, the quick-connect assembly is inverted U-shaped, the clamping parts 311 are located on both sides of the lower end of the connecting plate 312, the two clamping parts 311 are L-shaped with openings facing each other, the clamping parts 311 limit the connecting part 21 from both sides, the wire harness connecting end 313 is located at the lower end of the connecting plate 312, between the two clamping parts 311 near one edge, the wire harness connecting end 313 is provided with an internally hollow wire harness space, the internal back of the wire harness connecting end 313 is... The board has a wiring harness passage 3131, and the upper end of the wiring harness connection end 313 also has a wiring harness passage 3131. One end of the communication wiring harness connects to the wiring harness connection end 25, and the other end of the communication wiring harness extends out of the wiring harness connection end 313 in an L-shape. The wiring harness connection end 313 is equipped with an external back plate, which enhances the sealing performance of the wiring harness connection end 25, reduces the risk of rust or short circuit at the wiring harness connection end 25 in humid or corrosive environments, and prevents the fire extinguishing bomb from activating properly, thus ensuring the service life of the quick-connect fire extinguishing bomb. The mounting hole 3111 is circular, and the external control 322 is an L-shaped knob. The rotating section 3211 is located inside the switch mounting hole 3111. During installation, the external control 322 passes through the switch mounting hole 3111 from the outside of the clamping part 311. Due to the size limitation of the switch mounting hole 3111, the external control 322 cannot slide out radially. The external control 322 abuts against the rotating section 3211, allowing the rotating section 3211 to rotate with the external control 322. The part of the external control 322 that abuts against the rotating section 3211... The end is a semi-cylinder, the rotating section 3211 is a cylinder, the end of the rotating section 3211 that abuts against the external control 322 of the switch is a semi-cylinder, the concave section 3201 is a semi-cylinder, the external control 322 of the switch has a groove for accommodating the locking member 3231, the end of the locking member 3231 that protrudes from the groove is a hemisphere, the switch slot 3112 is a hemispherical slot, the locking member 3231 is embedded in the switch slot 3112 to restrict the rotation of the external control 322 of the switch, and the clamping part 311 has a locking groove for accommodating the locking end 3212.
