Abstract
Description
Technical Field
[0001] This utility model relates to the field of flushing device technology, and in particular to a flushing device for building water supply and drainage ditches. Background Technology
[0002] Building water supply and drainage is an applied technology that studies the supply of water and the collection and treatment of wastewater in industrial and civil buildings. Ditches are a general term for waterways dug for irrigation or drainage. In order to ensure the smooth flow of ditches, they need to be cleaned regularly by flushing devices.
[0003] Existing flushing devices typically consist of a flushing head connected to a pipe. The flushing head is placed inside the sewer, and water sprayed from it washes the ditch. However, because the flushing head moves using the reaction force generated by the water spray, it cannot fully clean the ditch surface during movement, resulting in poor flushing performance. Furthermore, stubborn stains may adhere to the ditch surface during flushing, and simply spraying water from the flushing head is insufficient to completely remove these stains, leading to poor overall effectiveness. Therefore, we propose a ditch flushing device for building water supply and drainage systems. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a ditch flushing device for building water supply and drainage.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ditch flushing device for building water supply and drainage is designed, including an outer shell, a first receiving cavity inside the outer shell, a conveying pump installed inside the first receiving cavity, a water supply pipe connected to the inlet end of the conveying pump, one end of the water supply pipe extending to the outside of the outer shell and connected to an external water source, and a drain pipe connected to the outlet end of the conveying pump, a hollow shaft installed at one end of the outer shell, and one end of the drain pipe connected to the end of the hollow shaft;
[0006] A water collection head is rotatably connected to one end of the hollow shaft. Several second nozzles are installed on the edge of the water collection head away from the outer casing, and each second nozzle is inclined. At least one third nozzle is also installed on the side of the water collection head.
[0007] A threaded sleeve is fitted on the side of the hollow shaft, and the threaded sleeve is threadedly connected to the hollow shaft. A connecting ring is rotatably connected to one end of the threaded sleeve. Several second grooves are opened on the side edge of the connecting ring. A support rod is rotatably connected inside each of the second grooves. One end of the support rod is connected to a connecting rod through a hinge seat. Several first grooves are also opened on the side edge of the water collecting head. One end of each connecting rod extends into the corresponding first groove and is rotatably connected to the first groove. A wire brush is installed on the side of each connecting rod.
[0008] Preferably, the outer casing also has a second receiving cavity, on both sides of which a drive motor is installed, and track wheels are connected to both sides of the outer casing. The output shaft of each drive motor is connected to the corresponding track wheel.
[0009] Preferably, a plurality of first nozzles are installed on the side edge of the water collection head away from the second nozzle, and each first nozzle has its nozzle facing the outer casing and is inclined.
[0010] Preferably, the first nozzle and the connecting rod are staggered.
[0011] Preferably, there is a gap between the bottom of the outer shell and the bottom of the track wheel.
[0012] Preferably, the size of the water collection head is smaller than the inner diameter of the ditch.
[0013] Preferably, the housing has an internal mounting cavity, and a control main board is installed inside the mounting cavity. The control main board is connected to the delivery pump and the drive motor via wires.
[0014] The design scheme proposed in this utility model has the following beneficial effects in application:
[0015] 1. By tilting the second nozzle, when the pump delivers external water to the water collection head and sprays it out from the second, first, and third nozzles, the water collection head will rotate under the recoil force generated by the water sprayed from the second nozzle. This allows the first, second, and third nozzles to thoroughly wash the surface of the ditch, improving the effectiveness of the application.
[0016] 2. By rotating the threaded sleeve, the connecting ring can be moved along the hollow shaft. Then, under the action of the support rod and the connecting rod, the position of the wire brush can be adjusted. When the water collecting head rotates, the wire brush can contact the surface of the ditch under the action of centrifugal force, washing the surface of the ditch and cleaning away stubborn impurities adhering to the surface of the ditch, thus improving the use effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-4 A ditch flushing device for building water supply and drainage includes a housing 1, an installation cavity 18 is provided inside the housing 1, and a control motherboard 19 is installed inside the installation cavity 18. The control motherboard 19 is either a PCB circuit board or a microcontroller circuit board.
[0024] like Figure 3 and Figure 4 As shown, the interior of the outer casing 1 also has a second receiving cavity 16. Drive motors 17 are installed on both sides of the interior of the second receiving cavity 16, and track wheels 3 are connected to both sides of the outer casing 1. The output shaft of each drive motor 17 is connected to the corresponding track wheel 3. The drive motor 17 is connected to the control main board 19 through wires. In actual use, the operator places the outer casing 1 in the ditch, and then the drive motor 17 can drive the track wheels 3 to rotate, thereby controlling the outer casing 1 to move along the ditch.
[0025] like Figure 1 and Figure 3 As shown, the outer casing 1 has a first receiving cavity 14 inside, and a delivery pump 15 is installed inside the first receiving cavity 14. The water inlet end of the delivery pump 15 is connected to a water supply pipe 2. One end of the water supply pipe 2 extends to the outside of the outer casing 1 and is connected to an external water source. A drain pipe 22 is connected to the water outlet end of the delivery pump 15. A hollow shaft 20 is installed at one end of the outer casing 1, and one end of the drain pipe 22 is connected to the end of the hollow shaft 20. The delivery pump 15 is connected to the control main board 19 through a wire. In actual use, when the outer casing 1 moves in the ditch, the control main board 19 controls the delivery pump 15 to work. The delivery pump 15 delivers external water to the drain pipe 22 through the water supply pipe 2, and then delivers it to the hollow shaft 20 through the drain pipe 22.
[0026] like Figure 3As shown, a water collecting head 11 is rotatably connected to one end of the hollow shaft 20. Several second nozzles 10 are installed on the edge of the water collecting head 11 away from the outer casing 1. At least one third nozzle 12 is also installed on the side of the water collecting head 11. The water delivered into the hollow shaft 20 can flow to the water collecting head 11 and be sprayed out through the second nozzles 10 and the third nozzles 12 to wash the surface of the ditch and clean the impurities adhering to the surface of the ditch.
[0027] It should be noted that, as Figure 1 As shown, each second nozzle 10 is inclined, so the water sprayed from the second nozzle 10 will be subjected to a recoil force, which will cause the water collection head 11 to rotate. This allows the second nozzle 10 and the third nozzle 12 to thoroughly wash the surface of the ditch.
[0028] It should be noted that the size of the water collecting head 11 is smaller than the inner diameter of the ditch, so that when the outer shell 1 moves in the ditch, the water collecting head 11 will not rub against the ditch.
[0029] like Figure 1 and Figure 2 As shown, a threaded sleeve 4 is fitted on the side of the hollow shaft 20, and the threaded sleeve 4 is threadedly connected to the hollow shaft 20. One end of the threaded sleeve 4 is rotatably connected to a connecting ring 5. Several second grooves 21 are formed on the side edge of the connecting ring 5. Support rods 13 are rotatably connected inside each of the second grooves 21. One end of the support rod 13 is connected to a connecting rod 8 through a hinge seat. Several first grooves 9 are also formed on the side edge of the water collecting head 11. One end of each connecting rod 8 extends into the corresponding first groove 9 and is rotatably connected to the first groove 9. A wire brush 7 is installed on the side of each connecting rod 8. In actual use, the opening degree of the connecting rod 8 can be adjusted by rotating the threaded sleeve 4 under the action of the support rod 13, so that the position of the wire brush 7 is adapted to the size of the ditch. When the water collecting head 11 rotates, it will drive the wire brush 7 to rotate. Under the action of centrifugal force, the wire brush 7 will contact the surface of the ditch and wash the surface of the ditch, cleaning the residual impurities.
[0030] Specifically, in use, the operator places the outer casing 1 into the ditch to be flushed, then rotates the threaded sleeve 4. The threaded sleeve 4 drives the connecting ring 5 to move along the hollow shaft 20. The connecting ring 5 pushes the support rod 13, causing the support rod 13 to synchronously push the connecting rod 8 to rotate, thereby allowing the connecting rod 8 to open to a preset position. Then, the drive motor 17 is controlled to work, driving the track wheel 3 to rotate, causing the outer casing 1 to move along the ditch. While moving, the control board 19 controls the conveying pump 15 to work. The conveying pump 15 delivers external water through the water pipe 2 and then through the drain pipe 22 to the hollow shaft. Water flows along the hollow shaft 20 into the water collection head 11. Finally, the water is sprayed out through the first nozzle 6, the second nozzle 10, and the third nozzle 12 to wash the inner surface of the ditch. At the same time, the impact force generated by the second nozzle 10 will drive the water collection head 11 to rotate, which will drive the connecting rod 8 to rotate, thereby causing the wire brush 7 to rotate. Under the action of centrifugal force, the wire brush 7 will contact the inner surface of the ditch and scrub the inner surface of the ditch. At the same time, the water sprayed from the first nozzle 6 will rinse the area scrubbed by the wire brush 7 to remove impurities, thus completing the rinsing process.
[0031] Furthermore, such as Figure 1 and Figure 2 As shown, several first nozzles 6 are installed on the edge of the water collecting head 11 away from the second nozzle 10. Each first nozzle 6 has its nozzle facing the outer casing 1 and is set at an angle. The impurities cleaned by the wire brush 7 can be washed away through the first nozzles 6, improving the usage effect.
[0032] Furthermore, the first nozzle 6 and the connecting rod 8 are staggered, so that the water sprayed from the first nozzle 6 will not be blocked by the connecting rod 8, thus not hindering the washing effect.
[0033] Furthermore, such as Figure 1 As shown, there is a gap between the bottom of the outer shell 1 and the bottom of the track wheel 3, so that the bottom of the outer shell 1 will not be worn by the bottom of the ditch when the outer shell 1 moves in the ditch.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
