Description

Technical Field

[0001] The utility model belongs to the technical field of bridge drainage cleaning, in particular to a bridge drainage cleaning device. Background Art

[0002] When a bridge is built, in order to prevent water accumulation on the bridge, drains are usually set up on both sides of the bridge. The drains are connected to drainage pipes, and the water on the bridge surface is discharged into the municipal sewage network through the drainage pipes. When the drains are discharged, the accumulated water carries the mud on the bridge surface into the drains, and the mud will adhere to the drains or the walls of the drainage pipes, so the drains and drainage pipes need to be cleaned regularly.

[0003] Most bridge drainage is cleaned by cleaners using handheld water guns. However, the water flow from the existing water gun nozzles is too concentrated and can only clean the area where the water gun is facing. It has a good effect on cleaning the drain outlet, but as the water gun nozzle goes deep into the drainage pipe to clean the pipe wall, the water gun nozzle has a very small range of movement, so the efficiency of cleaning the mud on the pipe wall is extremely low and difficult to clean. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a bridge drainage cleaning device, which effectively solves the problem that the bridge drainage cleaning devices currently on the market are difficult to clean the drainage pipes.

[0006] Furthermore, a direct spray outlet is provided at the bottom of the direct spray head, a fixing frame is provided inside the direct spray head, the fixing frame is provided above the direct spray outlet, the water supply pipe is provided with a positioning ring, the positioning ring is provided above the bottom oblique opening, and the positioning ring slides inside the straight spray head.

[0007] Furthermore, a rotating seal is provided at the center of the fixing frame, and the rotating seal is located directly below the bottom bevel. A return spring is also provided inside the straight nozzle, and one end of the return spring is connected to the fixing frame, and the other end of the return spring is connected to the outer wall of the bottom bevel. The rotating seal is arranged at the center position of the return spring.

[0008] Furthermore, the water supply pipe is also provided with a side wall hole. When the bottom bevel of the water supply pipe slides to the position of the rotating seal, the side wall hole is located in the side spray chamber. When the positioning ring of the water supply pipe slides to the top position of the straight spray head, the side wall hole is located at the positioning bevel.

[0009] Furthermore, the water supply pipe is also provided with a support ring retaining ring and a locking baffle, the support ring retaining ring is arranged above the positioning ramp, the locking baffle is arranged at the top of the water supply pipe, and a locking spring sheet is arranged below the locking baffle, and three circular arrays of the locking spring sheets are arranged around the locking baffle.

[0010] Furthermore, the connecting rod assembly includes a large support ring, the large support ring is arranged in the positioning groove, the large support ring is provided with a long rod support, and three circular arrays of the long rod supports are arranged outside the large support ring.

[0011] Furthermore, the connecting rod assembly includes a small support ring, which slides on the water supply pipe. The small support ring is arranged between the support ring retaining ring and the engaging baffle. The small support ring is provided with a short rod support, and three short rod supports are arranged in a circular array on the outside of the small support ring.

[0012] Furthermore, the connecting rod assembly also includes a long rod and a telescopic rod. A central support is provided at the center of the long rod, and the bottom of the long rod is hinged on the long rod support.

[0013] Furthermore, one end of the telescopic rod is hinged to the short rod support, and the other end of the telescopic rod is hinged to the central support.

[0014] Furthermore, when the small support ring slides to the position of the engaging baffle, it is engaged and connected with the engaging spring piece.

[0015] The beneficial effects achieved by the utility model are as follows:

[0016] 1. The direct spray outlet is contracted from the inside to the outside, increasing the water pressure so that the water can be sprayed out quickly to clean up the mud and sand. At the same time, a side spray chamber is provided on the water spray sleeve, which can spray water in all directions to flush the inner wall of the pipe.

[0017] 2. When the side wall hole of the water supply pipe is located in the side spray chamber, water flows out from the side wall hole into the side spray chamber, and when water flows out of the side wall hole, the rotating seal closes the bottom oblique mouth of the water supply pipe to ensure the water outlet pressure of the side wall hole. The rotating seal has a sealing effect and can rotate itself.

[0018] 3. When the side spray outlet of the side spray chamber ejects water, it will drive the water spray sleeve to rotate, effectively cleaning the inner wall of the pipe. The large support ring rotates inside the positioning groove, and the inner wall of the large support ring is designed to be arc-shaped, which reduces the contact surface with the positioning groove, thereby reducing the friction between the two, and further reducing the impact on the rotation of the water spray sleeve.

[0019] 4. When the cleaning staff is actually operating, the device is very likely to collide with the bridge facilities. The telescopic rod provides a certain buffering effect to prevent damage to the device, and the elastic coefficient of the telescopic rod itself is higher than the elastic coefficient of the return spring.

[0020] 5. The connecting rod assembly provides two working states for the water spray sleeve. When only the water spray sleeve is needed to provide direct water flow to clean the blockage, just fix the small support ring in the locking spring piece of the locking baffle, and the long rod and the telescopic rod will shrink and fit on both sides of the water supply pipe; when the inner wall of the pipe needs to be cleaned, the small support ring is removed from the locking spring piece, slid to the support ring retaining ring, and the long rod is unfolded. As the device enters the pipeline, the long rod is squeezed by the inner wall of the pipeline, and then the telescopic rod connected to the long rod moves the water spray sleeve upward, and at the same time the side wall hole moves to the side spray chamber, and the side spray outlet of the side spray chamber ejects water, and the rotating seal of the straight spray head closes the bottom oblique mouth of the water supply pipe, and the straight spray head will not produce direct water flow. When an external water pipe is required according to actual working conditions, an external hose or hard pipe can be selected. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The direct spray outlet 114 is contracted from the inside to the outside, increasing the water pressure so that the water can be sprayed out quickly to clean up the mud and sand. At the same time, a side spray chamber 12 is provided on the water spray sleeve 1, which can spray water to the surroundings to flush the inner wall of the pipeline.

[0032] A direct spray outlet 114 is provided at the bottom of the direct spray head 11, a fixing frame 111 is provided inside the direct spray head 11, the fixing frame 111 is provided above the direct spray outlet 114, and a positioning ring 22 is provided on the water supply pipe 2, the positioning ring 22 is provided above the bottom oblique opening 21, and the positioning ring 22 slides inside the direct spray head 11.

[0033] A rotating seal 112 is provided at the center of the fixed frame 111, and the rotating seal 112 is located directly below the bottom bevel 21. A return spring 113 is also provided inside the straight nozzle 11, and one end of the return spring 113 is connected to the fixed frame 111, and the other end of the return spring 113 is connected to the outer wall of the bottom bevel 21.

[0035] Among them, when the side wall hole 23 of the water supply pipe 2 is located in the side spray chamber 12, water flows into the side spray chamber from the side wall hole 23, and when water flows out of the side wall hole 23, the rotating seal 112 closes the bottom bevel 21 of the water supply pipe 2 to ensure the water outlet pressure of the side wall hole 23. The rotating seal 112 has a sealing effect and can rotate itself.

[0036] The water supply pipe 2 is also provided with a support ring retaining ring 24 and a locking baffle 25. The support ring retaining ring 24 is arranged above the positioning ramp 13, and the locking baffle 25 is arranged at the top of the water supply pipe 2. A locking spring piece 251 is provided below the locking baffle 25, and three locking spring pieces 251 are arranged in a circular array around the locking baffle 25.

[0038] Among them, when the side spray outlet 121 of the side spray chamber 12 ejects water, it will drive the water spray sleeve 1 to rotate, effectively cleaning the inner wall of the pipe, and the large support ring 31 rotates inside the positioning groove 131, and the inner wall of the large support ring 31 is designed to be arc-shaped, reducing the contact area with the positioning groove 131, thereby reducing the friction between the two, and further reducing the impact on the rotation of the water spray sleeve 1.

[0039] The connecting rod assembly 3 includes a small support ring 32, which slides on the water supply pipe 2. The small support ring 32 is arranged between the support ring retaining ring 24 and the engaging baffle 25. The small support ring 32 is provided with a short rod support 321, and three short rod supports 321 are arranged in a circular array on the outside of the small support ring 32.

[0040] The connecting rod assembly 3 further comprises a long rod 33 and a telescopic rod 34 . A central support 331 is provided at the center of the long rod 33 , and the bottom of the long rod 33 is hinged on the long rod support 311 .

[0041] When the cleaning staff is actually operating, the device is very likely to collide with the bridge facilities. The telescopic rod 34 provides a certain buffering effect to prevent the device from being damaged, and the elastic coefficient of the telescopic rod 34 itself is higher than the elastic coefficient of the return spring 113.

[0042] One end of the telescopic rod 34 is hinged to the short rod support 321 , and the other end of the telescopic rod 34 is hinged to the central support 331 .

[0043] When the small support ring 32 slides to the position of engaging the baffle plate 25 , it engages with the engaging spring piece 251 .

[0044] Among them, the connecting rod assembly 3 provides two working states for the water spray sleeve 1. When only the water spray sleeve 1 is needed to provide direct water flow to clean the blockage, it is only necessary to fix the small support ring 32 in the locking spring piece 251 of the locking baffle 25, and the long rod 33 and the telescopic rod 34 are contracted and fitted on both sides of the water supply pipe 2; when the inner wall of the pipeline needs to be cleaned, the small support ring 32 is removed from the locking spring piece 251, slid to the support ring retaining ring 24, and the long rod 33 is unfolded. As the device enters the pipeline, the long rod 33 is squeezed by the inner wall of the pipeline, and then the telescopic rod connected to the long rod 33 moves the water spray sleeve 1 upward, and at the same time the side wall hole 23 moves to the side spray chamber 12, and the side spray outlet 121 of the side spray chamber 12 ejects water, and the rotating seal 112 of the direct spray head 11 closes the bottom oblique mouth 21 of the water supply pipe 2, and the direct spray head 11 does not generate direct water flow.

[0045] When in use, the top of the water supply pipe 2 is installed on the water supply hose. When cleaning the outside and the drain outlet of the bridge drain pipe, only the water spray sleeve 1 is needed to provide a direct water flow. The small support ring 32 is slid to the engaging baffle 25. The engaging spring piece 251 on the engaging baffle 25 fixes the small support ring 32. At this time, the hinge position of the small support ring 32 and the telescopic rod 34 is higher than the hinge position of the telescopic rod 34 and the central support 331. The side wall hole 23 of the water supply pipe 2 is located at the position of the positioning ramp 13 at the upper end of the side spray chamber 12. The positioning ramp 13 closes the side wall hole 23. Water flows out from the bottom ramp 21 at the bottom of the water supply pipe 2 and enters the straight spray head 11. The water flows out from the straight spray outlet 114 of the straight spray head 11.

[0046] When the inner wall of the bridge drainage pipe needs to be cleaned, the small support ring 32 is moved downward to disengage the fixing of the engaging spring piece 251. When the engaging baffle plate 25 is moved downward, the telescopic rod 34 pushes the long rod 33 to unfold. At this time, the hinged position of the telescopic rod 34 and the central support 331 is higher than the hinged position of the small support ring 32 and the telescopic rod 34. As the device enters the bridge drainage pipe, the inner wall of the pipe squeezes the long rod 33 to shrink inward, and the long rod 33 pushes the telescopic rod 34 to move inward. The telescopic rod 34 is fixed on the support ring retaining ring 24, so that the telescopic rod 34 supports the long rod 33 to move upward , the large support ring 31 connected by the long rod 33 drives the water spray sleeve 1 to move upward. When the water spray sleeve 1 moves upward, the fixing frame 111 of the straight spray head 11 moves upward, and the fixing frame 111 compresses the reset spring 113. At the same time, the rotating seal 112 closes the bottom oblique mouth 21, and the straight spray head 11 no longer ejects water. After the side spray chamber 12 moves upward, the side wall hole 23 is connected to the side spray chamber 12, and the water flows into the side spray chamber 12 and is ejected from the side spray outlet 121. At the same time, the water ejected from the side spray outlet 121 drives the water spray sleeve 1 to rotate, thereby cleaning the inner wall of the bridge drainage pipe.
