All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Referring to Figures 1-4 , a building fire protection system water test detection device provided by the present invention includes a collection box 1. At the top of the inner wall of the collection box 1, two symmetrically distributed partition plates 1 are fixedly connected. On one side of one of the partition plates 1, a driving assembly is provided. At the top of the driving assembly, a convex brush plate 3 is provided. At the bottom of the partition plate 1, an installation groove 4 is opened. At the top of the inner wall of the installation groove 4, a telescopic assembly is provided. At the bottom of the collection box 1, two symmetrically distributed partition plates 5 are fixedly connected. On both sides of the collection box 1, collection cabinets 6 are inserted. At the top of the collection cabinet 6 and inside the collection box 1, a guide plate 7 is fixedly connected. On the front of the collection box 1, two symmetrically distributed fixing components are provided. On the front of the collection box 1, a connection component is provided. On one side of the connection component and inside the collection box 1, a filter screen 8 is provided. There is a certain distance between the bottom of the partition plate 1 and the top of the partition plate 5, and the height is the same as the height of the lower half of the convex brush plate 3. The driving assembly is used to drive the bottom of the convex brush plate 3 to move on the filter screen 8, and the guide plate 7 is used to guide the particulate impurities, facilitating the particulate impurities to enter the collection cabinet 6.

[0030] Between the opposite sides of the two partition plates 1, a U-shaped frame 9 is fixedly connected. The driving assembly includes a driving motor 10 fixedly connected to one side of one of the partition plates 1. The output end of the driving motor 10 is fixedly connected with a reciprocating lead screw 11. The outer surface of the reciprocating lead screw 11 is threadedly connected with a connecting strip 12. The top of the connecting strip 12 is slidably connected to the top of the inner wall of the U-shaped frame 9. The top of the convex brush plate 3 is fixedly connected to the bottom of the connecting strip 12. The output end of the driving motor 10 penetrates one of the partition plates 1.

[0031] The telescopic assembly includes an electric telescopic rod 13 installed at the top of the inner wall of the installation groove 4. One end of the electric telescopic rod 13 is fixedly connected with a baffle 14. The top of the baffle 14 abuts against the top of the partition plate 5.

[0032] The fixing component includes a damping rotating shaft 21 provided on the surface of the collection box 1. A fixing strip 22 is provided outside the damping rotating shaft 21.

[0033] The connection component includes a convex strip 15 inserted into the surface of the collection box 1. Two fixing grooves 16 are opened at the top of the convex strip 15. The fixing strip 22 is adapted to the fixing grooves 16. The filter screen 8 is fixedly connected to one side of the convex strip 15.

[0034] A connecting pipe 17 is fixedly connected to the top of the collection box 1. A water pressure sensor 18 is provided on the outside of the connecting pipe 17. The water pressure sensor 18 is used to detect the pressure of the water in the water pipe.

[0035] The outside of the collection box 1 is fixedly connected to a drainage pipe 19 , and the outsides of the drainage pipe 19 and the connecting pipe 17 are both provided with solenoid valves 20 .

[0036] Working principle: When water testing is required, the device is moved to the designated position, first connected to the fire hose through the connecting pipe 17, then the fire hose is opened, so that water flows into the connecting pipe 17 and then into the inner cavity of the collection box 1 and the water pressure of the connecting pipe 17 is detected by the water pressure sensor 18. The impurities in the water can be effectively filtered through the filter 8. At this time, the two electric telescopic rods 13 are in the extended state, so that the two baffles 14 respectively block the gap between the two partitions 1 2 and the two partitions 2 5.

[0037] When the filter 8 needs to be cleaned, the two electric telescopic rods 13 are first started to drive the two baffles 14 to retract respectively. After the two electric telescopic rods 13 are retracted, the two electric telescopic rods 13 are closed. At this time, the gap between the partition 1 2 and the partition 2 5 is not blocked. Then, the reciprocating screw rod 11 is driven to rotate by the driving motor 10, so that the connecting strip 12 drives the convex brush plate 3 to reciprocate along the U-shaped frame 9 on the filter 8. At this time, the convex brush plate 3 will pass through the gap between the partition 1 2 and the partition 2 5, thereby pushing the impurities on the filter 8 and dropping them into the two collection cabinets 6 under the action of the guide plate 7, so that the filter 8 can be cleaned.

[0038] When the filter 8 needs to be disassembled and replaced, the two fixing bars 22 are rotated to disengage the fixing bars 22, thereby releasing the fixation of the convex bar 15, making it convenient to pull out the convex bar 15 and the filter 8, and then the new convex bar 15 and the filter 8 are inserted into the collection box 1, and then the two fixing bars 22 are rotated to make the two fixing bars 22 enter the two fixing grooves 16 respectively, so that the convex bar 15 is fixed, completing the fixation of the convex bar 15.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
