Description

Technical Field

[0001] This utility model relates to the field of reservoir vertical detection equipment, and in particular to a reservoir stratified water intake device based on water level elevation. Background Technology

[0002] After a reservoir dam is built, the water temperature within the reservoir exhibits a distinct stratification along depth, especially at high-head power stations, where the temperature difference between the surface and bottom water can sometimes reach 20°C. The release of low-temperature bottom water from the reservoir alters the original river temperature distribution, impacting the ecological environment of downstream sections.

[0003] Due to the high water level of the dam, conventional water temperature detection equipment has limited detection depth and it is difficult to measure the temperature stratification areas. At the same time, the water is often mixed with silt and algae, which can easily affect water intake and detection. In order to address this technical problem, this application proposes a reservoir stratification water intake device based on water level elevation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stratified water intake device for reservoirs based on water level elevation. The horn-shaped shell can control the flow velocity of the water at its inlet, and in conjunction with the debris-blocking screen, it can prevent excessive flow velocity from bringing in large amounts of sludge and impurities, thus preventing obstruction. The outer end of the small tube is conical, which reduces drag and increases speed, allowing the water to flow quickly over its surface. This allows the water to enter the small tube from the inlet hole, while the sand and gravel mixed in the water are impacted and discharged from the sand discharge pipe, reducing the possibility of them entering the small tube and ensuring the quality of the water intake.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A reservoir stratified water intake device based on water level elevation includes a concrete main body. A water intake pipe is inserted through the front end of the concrete main body. A large pipe is fixedly connected to the outer wall of the water intake pipe. A horn shell is fixedly connected to the outer end of each large pipe. A debris-blocking net is fixedly connected to the inner wall of each horn shell. A small pipe is inserted through the outer wall of the water intake pipe corresponding to the inside of the large pipe. A traction rope is connected to the front end of the concrete main body through a control component. A shielding component is provided at the other end of the traction rope.

[0007] Furthermore, the bottom end of each of the large pipes is provided with multiple sand discharge pipes, and the front side of the outer wall of each of the small pipes is provided with multiple water inlet holes.

[0008] Furthermore, the control component includes multiple fixed rods fixedly connected to the front end of the concrete body, each fixed rod having a retainer fixedly connected to its top end, each retainer having a handle engaged on its inner wall, and one end of each traction rope fixedly connected to the front end of the handle.

[0009] Furthermore, each of the fixed rods has a pulley fixedly connected to its front end, and the outer wall of each traction rope is wrapped around the outer wall of the pulley.

[0010] Furthermore, the shielding assembly includes hooks fixedly connected to the other end of the traction rope, each hook having a retaining ring snapped into its inner wall, each retaining ring having a retaining plate fixedly connected to its bottom end, each retaining plate having a connecting block fixedly connected to its bottom end, and each connecting block having baffles fixedly connected to both its front and rear sides.

[0011] Furthermore, the rear end of the front baffle is tightly attached to the front end of the debris-blocking net cover, and the front end of the rear baffle is tightly attached to the rear end of the debris-blocking net cover.

[0012] Furthermore, multiple limiting plates are fixedly connected to the outer wall of the water inlet pipe, and the inner walls of the limiting plates are all set on the outer wall of the card plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the horn shell can control the flow rate of the water at its inlet. Combined with the debris screen, it can prevent a large amount of sludge and impurities from being brought close and blocked due to excessive flow rate. The small tube is tapered at one end, which can reduce drag and increase speed, allowing the water to flow quickly over its surface. This allows the water to enter the small tube from the inlet hole, while the sand and gravel mixed in the water are impacted and discharged from the sand discharge pipe, reducing the possibility of entering the small tube and ensuring the quality of the water intake.

[0015] 2. In this utility model, the handle can pull the traction rope to move on the pulley, thereby driving the baffle to move upward and expose the debris screen, controlling the water intake of the horn shell. When the baffle is reset, it will also scrape off the debris accumulated on the surface of the debris screen to prevent the debris from clogging the debris screen and affecting the next water intake test.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 An embodiment of this utility model is provided: a reservoir stratified water intake device based on water level elevation, comprising a concrete body 1, a water intake pipe 3 passing through the front end of the concrete body 1, a large pipe 12 fixedly connected to the outer wall of the water intake pipe 3, a horn shell 11 fixedly connected to the outer end of the large pipe 12, a debris screen 14 fixedly connected to the inner wall of the horn shell 11, a plurality of sand discharge pipes 13 passing through the bottom end of the large pipe 12, a small pipe 18 passing through the outer wall of the water intake pipe 3 corresponding to the inside of the large pipe 12, a plurality of water inlet holes 19 opening on the front side of the outer wall of the small pipe 18, a traction rope 2 connected to the front end of the concrete body 1 via a control component, the control component including a plurality of fixed rods 5 fixedly connected to the front end of the concrete body 1, a card seat 6 fixedly connected to the top of each fixed rod 5, a handle 15 clamped to the inner wall of each card seat 6, one end of the traction rope 2 fixedly connected to the front end of each handle 15, a pulley 7 fixedly connected to the front end of each fixed rod 5, and the outer wall of the traction rope 2 wrapped around the outer wall of the pulley 7;

[0024] Specifically, the flow rate of the water at the inlet of the horn shell 11 can be controlled to slow down the speed at which the water enters the interior of the horn shell 11, thus preventing a large amount of sludge and impurities from being carried close to the horn shell 11 due to excessive flow rate and affecting water intake. The debris screen 14 fixed on the inner wall of the horn shell 11 can block the impurities that are close to it. The outer end of the small tube 18 is tapered, which can reduce resistance and increase speed, allowing the water to flow quickly over its surface. This allows the water to enter the interior of the small tube 18 from the inlet hole 19. The sand and gravel mixed in the water are impacted and discharged from the sand discharge pipe 13, reducing the possibility of entering the interior of the small tube 18 and ensuring the quality of water intake. The handle 15 can pull the traction rope 2 to move on the pulley 7, thereby moving the baffle 10 upward to expose the debris screen 14 and control the water intake of the horn shell 11.

[0025] The other end of the traction rope 2 is equipped with a shielding component. The shielding component includes a hook 16 fixedly connected to the other end of the traction rope 2. The inner wall of the hook 16 is clamped with a retaining ring 17. The bottom end of the retaining ring 17 is fixedly connected with a retaining plate 8. The bottom end of the retaining plate 8 is fixedly connected with a connecting block 9. The front and rear sides of the bottom end of the connecting block 9 are fixedly connected with baffles 10. The rear end of the front baffle 10 is tightly attached to the front end of the debris-blocking net cover 14, and the front end of the rear baffle 10 is tightly attached to the rear end of the debris-blocking net cover 14. Multiple limiting plates 4 are fixedly connected to the outer wall of the water pipe 3. The inner wall of the limiting plate 4 is set on the outer wall of the retaining plate 8.

[0026] Specifically, by pulling the traction rope 2, the baffle 10 can be raised to collect water. The clamping plate 8, which is fixed on the upper side of the baffle 10 by the connecting block 9, slides on the inner wall of the limiting plate 4. This allows the baffle 10 to be limited by the limiting plate 4 after it is completely raised and detached from the inside of the horn shell 11. This prevents the baffle 10 from floating and shifting due to water flow impact, and thus prevents it from being unable to reset and block the debris screen 14. When the baffle 10 resets, it will also scrape off the debris accumulated on the surface of the debris screen 14 to prevent debris from clogging the debris screen 14 and affecting the next water collection test.

[0027] Working principle: In practical use, when it is necessary to test water intake from the reservoir, the corresponding handle 15 can be removed from the seat 6 according to the required water level. Then, pull the handle 15 to move the traction rope 2. With the help of the pulley 7, the hook 16 on the traction rope 2 can pull the plate 8 up, causing the baffle 10 to move upward and expose the debris screen 14. At this time, the water at this level can enter the inside of the horn shell 11 along the debris screen 14. After the flow rate is controlled by the horn shell 11, it enters the inside of the main pipe 12. At this time, the pump body connected to the water inlet pipe 3 can be started to generate suction in the small pipe 18, so that water is drawn through the multiple water inlet holes 1 on the small pipe 18. 9 enters the small pipe 18 and is then discharged through the water inlet pipe 3 for collection and testing. During this process, sludge and other impurities at this water level will be blocked by the debris screen 14, while fine sand mixed in the water will be blocked by the water inlet hole 19 and accumulate at the bottom of the large pipe 12. Finally, it will be discharged from the sand discharge pipe 13 to ensure the cleanliness of the water. After water collection is completed, the handle 15 can be released to reset the baffle 10 and re-cover the debris screen 14 to prevent water from entering the large pipe 12 and affecting the accuracy of water collection at other water levels. When the baffle 10 is reset, it will also scrape off the debris accumulated on the surface of the debris screen 14 to prevent debris from clogging the debris screen 14 and affecting the next water collection test.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
