Description

Technical Field

[0001] This utility model relates to the field of gas leakage detection technology, and in particular to a drainage device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production.

[0003] In the prior art, such as the drainage device for water conservancy projects described in Chinese Patent CN 222140085 U, a base is provided. Each base has four casters at its four corners. A fixing plate is welded to the front of the top of the base. Two motors A are symmetrically fixed to the top of the rear of the base. The output of motor A is connected to a water pipe bracket. The other end of the outlet pipe is placed on the other side of the dam or riverbank, so that the height of the outlet end of the outlet pipe is lower than the height of the inlet end of the inlet pipe. Then, motor B drives impeller B to rotate, causing impeller B to draw air out of the inlet and outlet pipes. Under pressure, the air flows out of the outlet pipe. Motor B is then turned off. The pressure difference allows water to be continuously pumped out of the dam, achieving a drainage effect. This pressure difference drainage method avoids the resource waste and power outage problems associated with using water pumps. However, this patent still has the following problems.

[0004] Although the aforementioned patent includes wheels to facilitate device movement, when the device is performing drainage operations, especially when the water flow rate is high or the pressure inside the pipe is high, the device may shake or even tip over due to uneven force, affecting the normal progress of the drainage operation and thus affecting drainage.

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.

[0027] Example 1, such as Figures 1-5 As shown, this utility model provides a drainage device for water conservancy projects, including a base 1, a storage groove 19 inside the base 1, a second motor 10 fixedly installed on the top of the base 1, the output end of the second motor 10 entering the storage groove 19 and a worm gear 20 fixedly installed thereon, fixed grooves 22 on both sides of the outer side of the base 1, two worm wheels 21 rotatably installed inside the storage groove 19, both worm wheels 21 meshing with the worm gear 20, a second threaded rod 25 fixedly installed on the opposite side of the two worm wheels 21, one end of the second threaded rod 25 entering the fixed groove 22, an extension plate 23 slidably installed inside the fixed groove 22, a threaded groove 24 opened at one end of the extension plate 23, the second threaded rod 25 threadedly connected to the threaded groove 24, an operating plate 11 fixedly installed on the outer wall of the extension plate 23, two first threaded holes 12 penetrating through the top of the operating plate 11, a first threaded rod 13 threadedly connected inside the first threaded holes 12, a handle 14 fixedly installed on the top of the first threaded rod 13, and a pin 15 fixedly installed on the bottom of the first threaded rod 13.

[0028] The overall effect of Embodiment 1 is as follows: When in use, the operator starts the second motor 10, and the output end of the second motor 10 drives the worm gear 20 to rotate, causing the two worm wheels 21 to rotate and the two second threaded rods 25 to rotate. The extension plate 23 moves along the fixed groove 22, and the two operating plates 11 move away from each other. Finally, the operator rotates the four handles 14, and the handles 14 drive the first threaded rod 13 to rotate. The first threaded rod 13 descends along the first threaded hole 12, and the ejector pins 15 descend until all four ejector pins 15 are in contact with the ground. This increases the support area and improves the support stability.

[0029] Example 2, as Figures 1-5 As shown, further, two first motors 4 are fixedly installed on the top of the base 1, and rollers 5 are fixedly installed on the output end of the first motors 4. The outer walls of the two rollers 5 are respectively wound with a first water pipe 6 and a second water pipe 8.

[0030] Furthermore, a filter frame 18 is fixedly installed at one end of the second water pipe 8. Two slots 29 are opened at one end of the filter frame 18. A limiting groove 32 is opened on the inner wall of the slot 29. A second threaded hole 33 is opened through the inner wall of the limiting groove 32. A third threaded rod 34 is threadedly connected inside the second threaded hole 33. A handle 36 is fixedly installed at one end of the third threaded rod 34. A connecting block 35 is fixedly installed at the end of the third threaded rod 34 away from the handle 36.

[0031] Furthermore, insert plates 30 are slidably installed inside both slots 29, and slots 31 are provided on the outer wall of the insert plates 30. Filter screens 28 are fixedly installed at one end of the two insert plates 30.

[0032] Furthermore, a protective shell 17 is fixedly installed at one end of the first water pipe 6, a support plate 37 is fixedly installed on the inner wall of the protective shell 17, a protective box 38 is fixedly installed on the outer wall of the support plate 37, a third motor 39 is fixedly installed on the inner wall of the protective box 38, and an impeller 40 is fixedly installed at the output end of the third motor 39 through the protective box 38 and the support plate 37.

[0033] Furthermore, a connecting pipe 9 is fixedly connected to one end of the second water pipe 8, and a threaded pipe 7 is fixedly installed at one end of the first water pipe 6. The threaded pipe 7 is threadedly connected to the connecting pipe 9.

[0034] Furthermore, two placement plates 16 are fixedly installed on the top of the base 1, and one end of the first water pipe 6 and the second water pipe 8 respectively pass through the two placement plates 16 and are slidably connected to the placement plates 16.

[0035] Furthermore, each of the four corners of the top of the base 1 is equipped with a caster wheel 2.

[0036] Furthermore, a handrail 3 is fixedly installed on the top of the base 1 to facilitate the movement of the device by staff.

[0037] Furthermore, a sliding groove 26 is provided on the inner wall of the fixing groove 22, and a slider 27 is fixedly installed on the outer wall of the extension plate 23. The slider 27 is slidably connected to the sliding groove 26 to prevent the extension plate 23 from leaving the fixing groove 22.

[0038] The effect achieved by the entire embodiment 2 is that when cleaning the filter screen 28, the operator turns the handle 36, the third threaded rod 34 rotates, the third threaded rod 34 moves along the second threaded hole 33, so that the connecting block 35 leaves the slot 31. At this time, the operator can pull out the insert plate 30 to clean and replace the filter screen 28. Finally, the insert plate 30 is inserted into the slot 29, the handle 36 is turned in the opposite direction, and the connecting block 35 enters the slot 31. The installation is thus completed, which improves the cleaning and replacement efficiency.

[0039] Working principle: When in use, the operator starts the second motor 10. The output end of the second motor 10 drives the worm gear 20 to rotate, causing the two worm wheels 21 to rotate and the two second threaded rods 25 to rotate. The extension plate 23 moves along the fixed groove 22, and the two operating plates 11 move away from each other. Finally, the operator rotates the four handles 14, which drive the first threaded rod 13 to rotate. The first threaded rod 13 descends along the first threaded hole 12, and the ejector pins 15 descend until all four ejector pins 15 are in contact with the ground. This increases the support area and improves the support stability. Then, the workers connect the threaded pipe 7 to the connecting pipe 9, put one end of the second water pipe 8 into the water in the dam or riverbank, and then put the other end of the first water pipe 6 on the other side of the dam or riverbank, so that the height of the outlet end of the first water pipe 6 is lower than the height of the inlet end of the second water pipe 8. Then, the third motor 39 is started and the impeller 40 is rotated, so that the impeller 40 draws out the air in the first water pipe 6 and the second water pipe 8. Under the action of pressure, the water in the dam or riverbank will flow through the second water pipe 8 into the first water pipe 6. At this time, the third motor 39 is turned off. By using the pressure difference, the water in the dam is continuously pumped out, which plays a role in drainage. The drainage is carried out by using the pressure difference. When cleaning the filter screen 28, the operator turns the handle 36, the third threaded rod 34 rotates, and the third threaded rod 34 moves along the second threaded hole 33, causing the connecting block 35 to leave the slot 31. At this time, the operator can pull out the insert plate 30 to clean and replace the filter screen 28. Finally, insert the insert plate 30 into the slot 29, turn the handle 36 in the opposite direction, and the connecting block 35 enters the slot 31. This completes the installation and improves the efficiency of cleaning and replacement.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
