Description

Technical Field

[0001] This utility model relates to the field of building fire protection technology, and in particular to a device for preventing insects and pests in the drainage pipes of a fire protection system. Background Technology

[0002] In the design of fire protection systems for new and renovated projects such as hotels, offices, factories, shopping malls, and hospitals, automatic sprinkler systems (hereinafter referred to as sprinkler systems) are frequently required. These systems consist of sprinkler heads, alarm valve assemblies, flow indicators, pressure switches, as well as piping, water supply facilities, and drainage facilities. They are fire extinguishing systems that automatically spray water in the event of a fire. The drainage facilities of a sprinkler system include: drain risers, drain branch pipes, test valves, end-of-line test devices, test connectors, and drain funnels. The end-of-line test device is used during sprinkler system testing to measure the water pressure and flow rate at the system's end, and is used twice a year.

[0003] Current technology typically requires the air gap height to be between 30-50mm, and the drain funnel remains open year-round. End-of-line testing devices are usually located in stairwells, bathrooms, or pipe shafts, easily leading to indoor environmental pollution and pest infestations. The drain funnel is 1.5 meters above the ground, making it susceptible to blockages from accidentally dropped objects. Therefore, a pest-proof and insect-proof device for fire protection system drain pipes is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology where the drainage funnel is always open, and unintentionally dropped items can easily cause blockage of the drainage pipe. Therefore, this invention proposes a pest and disease prevention device for the drainage pipe of a fire protection system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire protection system drainage pipe insect and pest prevention device, comprising a drainage funnel, a circular ring plate fixedly connected to the top of the drainage funnel, a fixing plate fixedly connected to the outer arc surface of the circular ring plate, pin blocks fixedly connected to the top and near both ends of the fixing plate, a protruding plate embedded between the pin blocks, a cover plate fixedly connected to the surface of the protruding plate, an annular groove formed on the top and near the inner edge of the circular ring plate, a sealing ring gasket embedded and fixedly connected inside the annular groove, a U-shaped plate fixedly connected to the outer arc surface of the circular ring plate, a locking block embedded inside the U-shaped plate, a fixing block fixedly connected to the top of the locking block, and a fixing block fixedly connected to the surface of the cover plate.

[0006] Preferably, a pin is connected through and fixedly connected to the protrusion of the convex plate, and both ends of the pin pass through the pin block and are rotatably connected to its bearing.

[0007] Preferably, a locking rod is slidably connected through the center of the locking block, one end of the locking rod passes through the U-shaped plate and is threadedly connected thereto, and the other end of the locking rod passes through the U-shaped plate and is slidably connected thereto.

[0008] Preferably, one end of the lever is fixedly connected to a rotating component, and the surface of the rotating component is symmetrically fixedly connected with protrusions.

[0009] Preferably, a circular groove is provided at one end of the fixing block.

[0010] Preferably, the bottom of the drainage funnel and near the center is fixed and connected to the drainage pipe body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, when the sprinkler system is in the ready state and the end test device is not working, the insect and pest prevention device of the fire protection system drain pipe body can be installed at the opening of the drain funnel. This can effectively block mosquitoes, rodents, and exhaust gases from entering the room, thereby preventing blockage of the drain pipe body.

[0013] 2. In this utility model, the sealing ring gasket inside the top annular groove of the circular plate can improve the sealing between the cover plate and the drainage funnel, thereby preventing gas from entering the drainage funnel from the gaps. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, as Figure 1-3 As shown, this utility model provides a fire protection system drainage pipe insect prevention and pest control device, including a drainage funnel 1. A circular ring plate 2 is fixedly connected to the top of the drainage funnel 1. A fixing plate 3 is fixedly connected to the outer arc surface of the circular ring plate 2. Pins 4 are fixedly connected to the top and near both ends of the fixing plate 3. A protruding plate 6 is embedded between the pins 4. A cover plate 5 is fixedly connected to the surface of the protruding plate 6, which can facilitate the opening of the cover plate 5. A ring groove 8 is formed on the top and near the inner edge of the circular ring plate 2. A sealing ring gasket 9 is embedded and fixedly connected inside the ring groove 8, which can seal the cover plate 5 and the circular ring plate 2. A U-shaped plate 10 is fixedly connected to the outer arc surface of the circular ring plate 2. A locking block 13 is embedded inside the U-shaped plate 10. A fixing block 11 is fixedly connected to the top of the locking block 13. The fixing block 11 is fixedly connected to the surface of the cover plate 5, which can fasten and fix the cover plate 5.

[0021] Example 2, as Figure 1-3 As shown, a pin 7 is connected and fixedly connected through the protrusion of the convex plate 6. Both ends of the pin 7 pass through the pin block 4 and are rotatably connected to its bearing, which can achieve the effect of pin-rotation connection at one end of the cover plate 5. A locking rod 14 is connected and slidably connected through the center of the locking block 13. One end of the locking rod 14 passes through the U-shaped plate 10 and is threaded to it. The other end of the locking rod 14 passes through the U-shaped plate 10 and is slidably connected to it, which can achieve the effect of fixing the locking block 13. A rotating part 15 is fixedly connected to one end of the locking rod 14.

A circular groove 12 is opened at one end of the fixing block 11, which can facilitate the pulling of the cover plate 5. A drain pipe body 16 is fixed and connected to the bottom of the drainage funnel 1 near the center, which can achieve the effect of drainage.

[0022] Working principle: The insect-proof and pest-preventing device of the drain pipe body 16 is installed at the open end of the test drain funnel 1 of the fire sprinkler system. Normally, the cover plate 5 can be covered. At the same time, the clamp rod 14 passes through the U-shaped plate 10 and the clamp block 13 to fix the cover plate 5, so that the insect-proof device is in a sealed working state, which can effectively prevent mosquitoes, insects and rodents and avoid blockage of the drain pipe body 16. Only before the sprinkler system is tested, the clamp is loosened and the insect-proof device is opened to make the drain funnel fully open. After the drainage test is completed, the insect-proof device is restored to a sealed working state.
