Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project drainage equipment, in particular to a drainage device used in water conservancy projects. Background Art

[0002] Water conservancy projects are a general term for various engineering projects constructed to control, utilize, and protect surface and underground water resources and the environment. These projects are built to eliminate water hazards and develop and utilize water resources. Based on the objectives they serve, they are categorized as flood control projects, agricultural water conservancy projects, hydropower generation projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple objectives, such as flood control, water supply, irrigation, and power generation, are called comprehensive water conservancy projects.

[0003] In water conservancy projects, water accumulation may occur due to various reasons. For example, condensation may occur due to temperature changes in the pipeline during operation, or a small amount of surface water may seep into certain parts. The drainage device can discharge the accumulated water in time to prevent the accumulated water from damaging the project structure. However, the existing drainage devices are difficult to use in construction sites and some cracks, and the accumulation of water in the water-logged part during use can easily block the water inlet, resulting in a decrease in the drainage effect. Based on this, a drainage device for water conservancy projects is proposed. Utility Model Content

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: a drainage device for water conservancy projects, including a curved pipe 1, a mounting frame 2 is fixedly installed on the outside of the curved pipe 1, a waterproof motor 3 is fixedly installed inside the other side of the mounting frame 2, the output end of the waterproof motor 3 is connected to a transmission rod 11, two sealed bearings 5 ​​are sleeved on the outside of the transmission rod 11, a protective sleeve 4 is movably passed through the outside of the transmission rod 11, a tapered thread transmission plate 12 is fixedly installed on the outside of the transmission rod 11, a plurality of turbine blades 13 are fixedly installed on the outside of the transmission rod 11, a cross bearing bracket 14 is movably sleeved on the outside of the end of the transmission rod 11 away from the protective sleeve 4, and a cone head 15 is fixedly installed on the end of the transmission rod 11 away from the waterproof motor 3. The outer side of one end of the bent pipe 1 is fixedly sleeved with a first flange 6, the end of the bent pipe 1 away from the first flange 6 is connected to a bellows 7, the other end of the bellows 7 is connected to a mounting pipe 16, the outer side of the mounting pipe 16 is fixedly sleeved with a second flange 8, the end of the mounting pipe 16 away from the bellows 7 is connected to a fixed pipe 17, the outer side of the fixed pipe 17 is fixedly sleeved with a third flange 21, the outer side of the fixed pipe 17 is fixedly sleeved with a second spherical mesh cover 18, the outer side of the second spherical mesh cover 18 is fixedly mounted with four inner arc plates 19, the outer sides of the four inner arc plates 19 are fixedly sleeved with a first spherical mesh cover 9, the outer side of the first spherical mesh cover 9 is fixedly mounted with four outer arc plates 10, and the inner wall of the fixed pipe 17 is fixedly mounted with an inner bracket 20.

[0021] The working principle of the above technical solution is as follows: when in use, the user puts the bellows 7 and the first spherical mesh cover 9 into a narrow position where water needs to be drained, and starts the waterproof motor 3 with an external power supply. The rotation of the waterproof motor 3 drives the transmission rod 11 to rotate. The transmission rod 11 rotates stably under the active support of the sealed bearing 5 and the cross bearing bracket 14, and drives the turbine blades 13 and the tapered thread transmission plate 12 to rotate. Suction is generated on the accumulated water through the bellows 7, the mounting pipe 16 and the fixed pipe 17, and the water flow is introduced into the interior of the bent pipe 1 through the fixed pipe 17, the mounting pipe 16 and the bellows 7, and is discharged through the pipe connected to the first flange 6 on the outside of the bent pipe 1. The overall use is easy and can be used in narrow and deeply water-logged locations. The overall slenderness makes it easy to carry and transfer.

[0022] In another embodiment, Figure 1-Figure 3As shown, the protective cover 4 is fixedly mounted on the outside of the elbow 1 , and the transmission rod 11 movably penetrates the inside of the elbow 1 and the protective cover 4 respectively through two sealed bearings 5 ​​.

[0023] The protective sleeve 4 provides protection for the connection between the transmission rod 11 and the bent pipe 1, and cooperates with the sealed bearing 5 to form a rotation support on the opposite sides of the bent pipe 1, the protective sleeve 4 and the transmission rod 11, and is assembled using a sealed structure to facilitate providing a rotation support for the transmission rod 11 parallel to one end of the bent pipe 1, thereby providing support for convenience of use.

[0024] In another embodiment, Figure 3 and Figure 4 As shown, the turbine blades 13 are evenly distributed on the outer side of the transmission rod 11 in a circumferential manner, and the end of the cross bearing bracket 14 away from the transmission rod 11 is fixedly installed on the inner wall of the elbow 1.

[0025] The turbine blades 13 and the tapered threaded transmission plate 12 extract the air flow and water flow inside the bent pipe 1 as the transmission rod 11 rotates, thereby improving the efficiency of water pumping and the efficiency of hydrophobicity. The cross bearing bracket 14 provides stable support for one end of the transmission rod 11 through the bearing and the bracket, thereby maintaining relative stability of rotation and torque.

[0026] In another embodiment, Figure 1-Figure 5 As shown, the third flange 21 and the second flange 8 are fixedly connected by bolts passing through.

[0027] The third flange 21 and the second flange 8 are connected by flange bolts, and a sealing gasket is provided at the connection, which facilitates the removal of the fixing pipe 17 and the installation pipe 16, increases the convenience of cleaning and maintenance, and facilitates the replacement of heads of different sizes.

[0028] In another embodiment, Figure 1-Figure 5 As shown, the outer arc plate 10 and the inner arc plate 19 are evenly distributed on the outside of the first spherical mesh cover 9 and the second spherical mesh cover 18 in a circumferential manner. The first spherical mesh cover 9 is fixedly sleeved on the outside of the fixed tube 17, and the fixed tube 17 extends to the inside of the second spherical mesh cover 18. The end of the inner bracket 20 away from the fixed tube 17 is fixedly installed on the inner wall of the second spherical mesh cover 18.

[0029] This solution forms a spherical mesh protection on the outside of the fixed pipe 17 through the first spherical mesh cover 9 and the outer arc plate 10. When drawing water, the mesh partitions separated on both sides can block impurities inside the water absorption range. As the outer arc plate 10 is raised, a certain gap of debris will not completely block the water inlet pipe position, so it will not be blocked during long-term use. The structural strength between the mesh structures is increased, and it can withstand the squeeze of falling rocks and debris on the construction site, indirectly increasing the service life.

[0030] In another embodiment, Figures 1-4 As shown, the elbow 1 is bent, and the bending angle of the elbow 1 is 45°.

[0031] The bent state of the curved pipe 1 facilitates support and does not rotate when placed on a flat surface, and can be placed in narrow grooves and crevices, making it easy to use in specific usage scenarios and increasing convenience.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
