[0023] Embodiment

[0024] See Figure 1-2 as shown in

[0025] The present utility model provides a pump pool water intake and silt flushing device, including: a water inlet pipe 10, a front pool 20, a water intake channel 30, a water intake pump 40, a collecting pipe 50, and a silt flushing assembly.

[0026] The water inlet pipe 10 introduces water into the front pool 20. One end of the water intake channel 30 is communicated with the top of the front pool 20, and the other end is communicated with the water intake pump 40; the water intake pump 40 transports the water in the water intake channel 30 into the collecting pipe 50. The collecting pipe 50 transports water to the place where water is used for the vaporizer, and the silt flushing assembly is communicated with the collecting pipe 50 and is installed in the front pool 20 for agitating the water flow at the bottom of the front pool 20.

[0027] By introducing the pressurized water in the collecting pipe 50 into the bottom of the front pool 20 to form an impact water flow, the water flow in the front pool 20 is agitated, preventing impurities and silt from settling and accumulating at the bottom of the front pool 20, thereby completing the automatic silt flushing work of the front pool 20 without affecting the operation of the front pool 20.

[0028] The silt flushing assembly includes a diversion pipe 60 and a flushing adjustment part. One end of the diversion pipe 60 is communicated with the collecting pipe 50, and the other end is communicated with the front pool 20. The flushing adjustment part is arranged on the diversion pipe 60 for flushing and agitating the bottom of the front pool 20.

[0029] The flushing adjustment part includes a nozzle 67 and a flushing adjustment member.

[0030] The nozzle 67 is installed at the bottom of the forebay 20 and is communicated with the draft tube 60. The flushing adjustment member is installed on the draft tube 60 and is connected to the nozzle 67 for adjusting the pressure and direction of the water flow ejected from the nozzle 67. The water outlet of the nozzle 67 is flat, and the nozzle 67 is inclined downward by 2°.

[0031] By setting the nozzle 67, when the water flow ejects from the nozzle 67, a greater impact force can be generated, and the flushing effect on the bottom of the forebay 20 is better.

[0032] The flushing adjustment member mainly consists of a first valve 61, a first pressure gauge 62, a pressure regulating valve 63, a second pressure gauge 64, a turning pipe 65 and a flushing branch pipe 66.

[0033] The first valve 61 is used to control the start and stop of the water supply in the draft tube 60, and the first pressure gauge 62 is used to monitor the water flow pressure in the draft tube 60; the pressure regulating valve 63 is used to adjust the pressure conveyed by the draft tube 60; the second pressure gauge 64 is used to monitor the pressure of the water flow regulated by the pressure regulating valve 63 in the draft tube 60 to ensure that the operator can always know whether the water flow pressure for flushing the bottom of the forebay 20 meets the flushing requirements.

[0034] The first valve 61, the first pressure gauge 62, the pressure regulating valve 63, and the second pressure gauge 64 are all installed on the draft tube 60 and are arranged in sequence along the direction of the water flow conveyed by the draft tube 60. One end of the turning pipe 65 is communicated with the draft tube 60, and the other end is communicated with the flushing branch pipe 66. The direction of the water flow is changed through the turning pipe 65. Especially when one draft tube 60 needs to flush multiple forebays 20, multiple turning pipes 65 are required to complete the diversion of the water flow. The flushing branch pipe 66 is installed on the side wall at the bottom end of the forebay 20. The nozzle 67 is communicated with the flushing branch pipe 66.

[0035] There are at least two flushing branch pipes 66, and they are located on both sides of the connection between the water inlet pipe 10 and the forebay 20. There are at least 3 nozzles 67 on the flushing branch pipe 66, and the spraying directions of the nozzles 67 in the forebay 20 jointly form a clockwise or counterclockwise direction. The flushing branch pipe 66 is made of a glass steel pipe with a diameter of DN100. The flushing branch pipe 66 is distributed in a ring shape along the bottom end of the forebay 20.

[0036] During actual use, according to the shape, depth and water storage capacity of the forebay 20, the flushing branch pipes 66 and nozzles 67 are correspondingly arranged to ensure that the water flow ejected by the nozzles 67 at the bottom end of the forebay 20 can form a circumferential agitation, turning the impurities at the bottom of the forebay 20 to the upper part of the forebay through the agitated circulating flow, and flowing into the water intake channel 30 together with the water flow overflowing from the forebay 20, thereby preventing impurities or silt deposition from occurring at the bottom of the forebay 20.

[0037] A first horizontal rod 71 and a second inclined rod 72 are provided at the connection between the flushing branch pipe 66 and the side wall at the bottom end of the forebay 20. One end of the first horizontal rod 71 is hinged to the side wall at the bottom end of the forebay 20, and a first fastening bolt 711 is provided at the hinge, and a long hole 713 is provided along the length direction of the first horizontal rod 71. One end of the second inclined rod 72 is hinged to the side wall at the bottom end of the forebay 20, and a second fastening bolt 721 is provided at the hinge, and the other end of the second inclined rod 72 is slidably connected to the long hole 713 through a third fastening bolt 712. The flushing branch pipe 66 is fixed on the first horizontal rod 71, and a hose is provided at the connection between the flushing branch pipe 66 and the steering pipe 65.

[0038] By adjusting the first fastening bolt 711, the second fastening bolt 721 and the third fastening bolt 712, the angle and height of the support frame formed by the first horizontal rod 71 and the second inclined rod 72 are changed, and further, the height of the flushing branch pipe 66 from the bottom end of the forebay 20 and the spraying angle of the nozzles 67 on the flushing branch pipe 66 with respect to the bottom end of the forebay 20 can be adjusted, so that it is convenient for the operator to make timely adjustments according to the flushing effect of the impurities or silt at the bottom of the forebay 20, ensuring the maximum flushing effect. At the same time, the flexibility of the entire device during use is also improved.

[0039] It should be noted that if there are directional indications involved in the embodiments of the present utility model, such as up, down, left, right, front, back..., the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the attached drawings. If the specific posture changes, the directional indications will also change accordingly. In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, "a plurality of" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
