[0001] This utility model belongs to the technical field of fire extinguishing devices, and particularly relates to a suspended automatic liquid fire extinguishing device. Background Technology

[0002] Suspended automatic liquid fire extinguishing devices are fire-fighting equipment that can be suspended and are mainly used to extinguish initial fires involving solids, liquids, and electrical equipment. When a fire occurs, the device automatically activates after the temperature sensing element is activated or a fire alarm signal is received, and the extinguishing agent is automatically sprayed down to extinguish the electrical fire. When suspended, the installation height should be appropriate to ensure that the extinguishing agent can effectively cover and protect the equipment.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing suspended automatic liquid fire extinguishing devices:

[0004] 1. The suspension ring of the device is installed on the fire extinguisher via threads, which is prone to loosening due to external forces. It is inconvenient to install anti-rotation measures on the device to prevent the suspension ring from loosening.

[0005] 2. The spray nozzles are easily bumped and knocked during the handling of the device, which may cause them to malfunction. It is inconvenient to install protective measures on the device to cover and protect the spray nozzles. Utility Model Content

This solves the problems of existing devices where the suspension ring is threaded onto the fire extinguishing tank, making it prone to loosening due to external forces, and making it inconvenient to install anti-rotation measures on the device to prevent loosening; and the device is also prone to damage to the spray nozzles during transport, causing them to malfunction, and making it inconvenient to install protective measures to cover and protect the spray nozzles.

[0007] The purpose and effectiveness of this utility model's suspended liquid automatic fire extinguishing device are achieved through the following specific technical means:

[0008] A suspended liquid automatic fire extinguishing device includes a device body; the device body is equipped with a suspended fire extinguishing tank, a suspended internal threaded cylinder is provided at the center of the top of the suspended fire extinguishing tank, six anti-rotation grooves are arranged in a ring array on the outer circumference of the upper end of the suspended internal threaded cylinder, an assembly internal threaded cylinder is provided at the center of the bottom of the suspended fire extinguishing tank, a through hole is provided at the center of the bottom wall of the suspended fire extinguishing tank, a bearing suspension ring is installed on the suspended internal threaded cylinder of the suspended fire extinguishing tank, a regular hexagonal prism is provided in the middle of the bearing suspension ring, a threaded post is provided on the bottom end face of the regular hexagonal prism of the bearing suspension ring, a hanging ring is provided on the top end face of the regular hexagonal prism of the bearing suspension ring, an anti-rotation and anti-loosening cylinder is inserted between the anti-rotation grooves of the suspended fire extinguishing tank, a bearing ring is provided in the middle of the anti-rotation and anti-loosening cylinder, six anti-rotation plates in the vertical direction are arranged in a ring array on the bearing ring of the anti-rotation and anti-loosening cylinder, and the top of the anti-rotation plates of the anti-rotation and anti-loosening cylinder is bent inward.

[0009] Furthermore, a nozzle guard is threadedly installed between the external threaded half-cylinders of the flip-opening frame. The nozzle guard has threads on its inner circumference at the top and anti-slip grooves in an annular array on its outer circumference.

[0010] Furthermore, a flip-opening frame is installed inside the limiting groove of the carrying support frame via a fixed shaft. The flip-opening frame is a C-shaped plate structure with the opening facing inward. The upper end of the flip-opening frame is provided with a semi-circular head with front and rear through holes, and the lower end of the flip-opening frame is provided with an externally threaded semi-cylinder with the opening facing inward in the up and down direction.

[0011] Furthermore, the outer circumference of the sleeve of the carrying support frame is provided with arc-shaped strips on both the left and right sides, and an L-shaped handle is provided at the top between the arc-shaped strips of the carrying support frame and the sleeve. The outer end of the arc-shaped strips of the carrying support frame is provided with a fixing hole that runs through the front and back, and the middle of the outer end face of the arc-shaped strips of the carrying support frame is provided with a limiting groove that runs through the top and bottom.

[0012] Furthermore, the suspended fire extinguisher is fitted with a carrying support frame on its internal threaded cylinder. The carrying support frame has a sleeve in the vertical direction at its center, and the sleeve of the carrying support frame has semi-circular grooves in the vertical direction on both the left and right sides of its inner circumference.

The suspension ring 3 is installed via threads. A through-hole hanging ring is provided on the top end face of the hexagonal prism supporting the suspension ring 3, facilitating the insertion of the hanging hook. An anti-rotation and anti-loosening cylinder 4 is inserted between the anti-rotation grooves of the fire extinguisher 2, facilitating anti-rotation of the anti-rotation and anti-loosening cylinder 4. A bearing ring is provided in the middle of the anti-rotation and anti-loosening cylinder 4, facilitating the support of the anti-rotation plates to form a whole. Six anti-rotation plates are arranged in a circular array in the vertical direction on the bearing ring of the anti-rotation and anti-loosening cylinder 4, facilitating deformation to support the suspension ring 3. The anti-rotation and anti-loosening cylinder 4 has an inward bend at the top of the anti-rotation plate, which facilitates the limiting of the hexagonal prism end face of the bearing suspension ring 3. The internal threaded cylinder of the suspended fire extinguisher 2 is equipped with an automatic fire extinguishing nozzle 5, which facilitates the automatic fire extinguishing of the device body 1 through the heat-sensing glass tube. The upper outer circumference of the automatic fire extinguishing nozzle 5 is provided with a regular hexagonal ring plate, which facilitates the automatic fire extinguishing nozzle 5 to be disassembled and assembled with tools. The upper outer circumference of the automatic fire extinguishing nozzle 5 is threaded, which facilitates the automatic fire extinguishing nozzle 5 to be installed by thread.

[0028] The automatic fire extinguisher nozzle 5 has a sealing rubber ring 6 on its top, which facilitates the sealing by deformation under force. The upper and lower surfaces of the sealing rubber ring 6 have spherical grooves to facilitate deformation under force. The outer circumference of the sealing rubber ring 6 also has rounded corners at both ends to facilitate deformation under force. A carrying support frame 7 is fitted onto the internal threaded cylinder of the suspended fire extinguisher 2 to facilitate the support of the tilting and opening frame 8. The carrying support frame 7 has a sleeve in the center facing up and down for easy lifting. The carrier frame 7 is assembled. The inner circumference of the sleeve of the carrying carrier frame 7 has semi-circular grooves on both sides, facilitating the insertion of the suspension ring 3. The outer circumference of the sleeve of the carrying carrier frame 7 has arc-shaped plates on both sides at the bottom, allowing for proper fit with the surface of the suspended fire extinguisher 2. An L-shaped handle is located at the top between the arc-shaped plates and the sleeve of the carrying carrier frame 7 for easy gripping and carrying. The outer end of the arc-shaped plates of the carrying carrier frame 7 has a through-hole for easy opening and closing. The frame 8 is rotated by mounting on a fixed shaft. The outer end face of the arc-shaped strip of the carrying support frame 7 has a vertically penetrating limiting groove, which facilitates the insertion of the rotating opening and closing frame 8 into the limiting groove. The rotating opening and closing frame 8 is installed inside the limiting groove of the carrying support frame 7 by a fixed shaft, which facilitates the rotation and opening of the rotating opening and closing frame 8. The rotating opening and closing frame 8 is a C-shaped plate structure with the opening facing inward, which facilitates the fitting with the surface of the suspended fire extinguisher 2. The upper end of the rotating opening and closing frame 8 is provided with a semi-circular head with front and rear through holes, which facilitates the rotation of the rotating opening and closing frame 8 by mounting on the fixed shaft. The lower end of the rotating opening and closing frame 8 is provided with an externally threaded semi-cylinder with the opening facing inward and vertically, which facilitates the installation of the nozzle protective cover 9 by thread. The nozzle protective cover 9 is installed on the outside of the externally threaded semi-cylinder of the rotating opening and closing frame 8 by thread, which facilitates the protection of the automatic fire extinguishing nozzle 5. The top inner circumference of the nozzle protective cover 9 is threaded, which facilitates the installation and removal of the nozzle protective cover 9 by thread. The outer circumference of the nozzle protective cover 9 is provided with an anti-slip groove array, which facilitates the rotation and anti-slip of the nozzle protective cover 9.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this invention, when assembling the various components of the device body 1, the anti-rotation plate of the anti-rotation and anti-loosening cylinder 4 is inserted into the anti-rotation groove of the suspended fire extinguisher 2, preventing the anti-rotation and anti-loosening cylinder 4 from rotating. The bearing suspension ring 3 is then screwed into the internal threaded cylinder of the suspended fire extinguisher 2 using a tool, locking and fixing the bearing suspension ring 3. The top of the anti-rotation and anti-loosening cylinder 4 is bent inward and deformed using a tool. The bending of the anti-rotation and anti-loosening cylinder 4 limits the six end faces of the regular hexagonal prism of the bearing suspension ring 3, thereby achieving anti-rotation and anti-loosening of the bearing suspension ring 3 and preventing it from rotating and loosening under vibration. The sealing rubber ring 6 is placed on top of the automatic fire extinguisher nozzle 5, and then the automatic fire extinguisher nozzle 5 is screwed into the internal threaded cylinder of the suspended fire extinguisher 2 using a tool. The automatic fire extinguisher nozzle 5 and the suspended fire extinguisher 2 compress the sealing rubber ring 6, causing it to elastically deform. This deformation of the sealing rubber ring 6 achieves a seal, as shown in the diagram. Figure 3 As shown, the device is currently in a suspended state. Then, the carrying support frame 7 with the flip-opening bracket 8 is fitted over the external threaded cylinder of the suspended fire extinguisher 2, so that the hanging ring of the bearing suspension ring 3 is positioned inside the semi-circular groove of the carrying support frame 7. This prevents the carrying support frame 7 from rotating through the bearing suspension ring 3, as shown in the diagram. Figure 6 As shown, the flip-opening and closing frame 8 is then flipped downwards and closed, so that the two external threaded half-cylinders of the flip-opening and closing frame 8 form a cylinder. The nozzle protective cover 9 is then threadedly installed on the outside of the cylinder formed by the external threaded half-cylinders of the flip-opening and closing frame 8, as shown in the figure. Figure 1 As shown, this is the transport protection state. The automatic fire extinguishing nozzle 5 is covered by the nozzle protective cover 9 to prevent bumps and collisions, and is carried and moved by the carrying support frame 7.

[0031] Example 2: The difference from Example 1 is that the regular hexagonal prism of the bearing suspension ring 3 can also be set as a regular heptagonal prism, so that the bearing suspension ring 3 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the bearing suspension ring 3.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal ring plate of the automatic fire extinguishing nozzle 5 can also be set as a regular heptagonal ring plate. This makes the automatic fire extinguishing nozzle 5 require a special tool that works with the regular heptagonal ring plate to rotate, thus preventing non-staff members from rotating or disassembling the automatic fire extinguishing nozzle 5.
