Description

Technical Field

[0001] This utility model relates to the field of ecological water conservancy engineering technology, and in particular to a tower-type surface water intake device for a small reservoir. Background Technology

[0002] Currently, research on water resource application and environmental protection has found that reservoir water levels can be divided into surface water and deep water. Surface water, due to longer hours of sunshine and higher water temperatures, has more active microorganisms, which is beneficial for agricultural irrigation and the survival needs of fish and other organisms in downstream rivers. Therefore, surface water should be used as much as possible for crop growth and the survival of fish in downstream rivers to increase metabolism. Surface water is also more conducive to fish spawning, meeting actual irrigation and agricultural needs.

[0003] The existing stratified water intake systems in water conservancy projects mainly include: vertical shaft + multi-layer impounding gate system, vertical shaft + stacked beam gate system, and sloping vertical shaft + stratified impounding gate system. These stratified water intake systems are mostly applicable to large reservoirs in domestic water conservancy projects. Therefore, they generally have complex structures, are difficult to operate, have long construction periods, high investment costs, and are relatively difficult to maintain and repair. The existing structural types of these systems are also not yet fully developed.

[0004] Based on the above problems, this utility model proposes a tower-type surface water intake device for small reservoirs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tower-type surface water intake device for a small reservoir. When the water level is higher than the pontoon, the pontoon rises due to buoyancy, causing the water baffle plate connected to it to move upward and block the water inlet below, thereby allowing the water inlet located on the water surface to take water. The surface water has a higher temperature due to long hours of sunshine, and microorganisms are more active, which is beneficial to agricultural irrigation and the survival needs of fish and other organisms in the lower reaches of the river. It increases metabolism and is conducive to fish spawning, thus meeting the actual irrigation and agricultural needs.

[0006] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows:

[0007] This utility model discloses a tower-type surface water intake device for a small reservoir, including a square water tower, a float, a baffle plate, and an outlet pipe. The square water tower is a hollow, closed-end square tubular structure. The front wall of the square water tower has several water inlets at equal intervals along the vertical direction. First slide rails are provided on both sides of the water inlets, and baffle plates that slide with the first slide rails and can block the water inlets are provided. Several second slide rails for the float to slide are staggered on the two side walls of the square water tower. The baffle plate at the lower water inlet is rigidly connected to the float on the side of the adjacent upper water inlet. The outlet pipe is provided on the lower rear wall of the square water tower.

[0008] The square water tower includes a bottom water tower unit, a first water tower unit, and a second water tower unit. The bottom water tower unit is a hollow square structure with an open top, and its bottom is fixed to the bottom of the water. The water inlet is located above its front wall, and the water outlet is located below its rear wall. Several first water tower units and second water tower units are staggered above the bottom water tower unit. The first water tower unit and the second water tower unit are square tubular structures. The right side wall of the first water tower unit and the left side wall of the second water tower unit are provided with second slide rails for the sliding of the float. The water inlet is located above the front wall of the first water tower unit and the second water tower unit. The first slide rails for the sliding of the baffle plate are located on both sides of the water inlet. The float on the right side wall of the lowest first water tower unit is connected to the baffle plate of the bottom water tower unit, and the float on the left side wall of the lowest second water tower unit is connected to the baffle plate of the lowest first water tower unit. The bottom water tower unit, the first water tower unit, and the second water tower unit are connected by a connecting mechanism.

[0009] The connecting mechanism includes a flange, an insertion frame, a sealing gasket, and connecting bolts. The flange has a square frame structure, and its inner wall cross-section is equal to that of the inner wall of the square water tower. The outer wall of the flange is provided with a number of bolt holes at intervals for the connecting bolts to pass through. The inner wall of the flange is connected to the insertion frame for insertion into the inner wall of the square water tower. The connecting bolts pass through the bolt holes on both sides of the flange and are connected to the connecting nuts.

[0010] The first slide rail includes a left first slide rail and a right first slide rail. The left first slide rail and the right first slide rail are arranged in a square structure on both sides of the water inlet. The inner wall of the left first slide rail and the right first slide rail is provided with a first sliding groove for the water baffle to slide. When the water baffle is located at the bottom of the first sliding groove, the float connected to the water baffle is located at the bottom of the second slide rail, and the top of the water baffle is located below the water inlet.

[0011] The second slide rail includes a left second slide rail and a right second slide rail, and the inner walls of the left second slide rail and the right second slide rail are provided with second sliding grooves; the float box has a hollow square structure, and its inner walls are provided with sliders that can slide in conjunction with the second sliding grooves.

[0012] The bottom end of the pontoon is connected to the front wall of the baffle below by a connecting rod. The connecting rod includes a vertical rod, a horizontal rod, and a longitudinal rod. The top end of the vertical rod is connected to the middle of the bottom end of the pontoon, the bottom end of the vertical rod is perpendicularly connected to one end of the horizontal rod, the other end of the horizontal rod is perpendicularly connected to one end of the longitudinal rod, and the other end of the longitudinal rod is connected to the middle of the front wall of the baffle.

[0013] The top end of the first or second water tower unit is hinged to one end of the tower cover, and the other end of the top of the first or second water tower unit is connected to the tower cover by a snap fastener.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) When the water level is higher than the pontoon, the pontoon floats up due to buoyancy, causing the water baffle connected to it to move up and block the water inlet below, so that the water inlet located on the water surface can take water. The surface water has a long sunshine time, a high water temperature, and active microorganisms, which is conducive to agricultural irrigation and the survival needs of fish and organisms in the lower reaches of the river. It increases metabolism and is conducive to the spawning needs of fish, thus meeting the actual irrigation and agricultural needs. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below:

[0024] Please see Figure 1-6 ,

[0025] This utility model discloses a tower-type surface water intake device for a small reservoir, including a square water tower 1, a float 2, a baffle plate 3, and an outlet pipe 4. The square water tower 1 is a hollow, closed-end square tubular structure. The front wall of the square water tower 1 has several water inlets 5 evenly spaced along the vertical direction. First slide rails 6 are provided on both sides of each water inlet 5, and baffle plates 3 that slide with and cooperate with the first slide rails 6 to block the water inlets 5 are provided. Several second slide rails 7 are alternately arranged on the side walls of the square water tower 1 for the float 2 to slide. The baffle plate 3 at the lower water inlet 5 is rigidly connected to the float 2 on the side of the adjacent upper water inlet 5. The lower part of the rear wall of the square water tower 1 has... The water outlet pipe 4 is described in this invention. When the water level is higher than the float box 2, the float box 2 floats up due to buoyancy, causing the water baffle 3 connected to it to move upward and block the water inlet 5 below. This allows the water inlet 5, located on the water surface, to take water. The surface water has a higher water temperature due to longer sunshine hours, and microorganisms are more active, which is beneficial for agricultural irrigation and the survival needs of fish and other organisms in the lower reaches of the river. It increases metabolism and is conducive to fish spawning, thus meeting actual irrigation and agricultural needs. The water taken from the water inlet 5 on the water surface flows out through the water outlet pipe 4 through the inner cavity of the square water tower 1. The first slide rail 6 and the second slide rail 7 are provided to ensure that the water baffle 3 and the float box 2 can move stably in the vertical direction.

[0026] Furthermore, such as Figure 1 and Figure 2As shown, the square water tower 1 includes a bottom water tower unit 11, a first water tower unit 12, and a second water tower unit 13. The bottom water tower unit 11 is a hollow square structure with an open top, and its bottom is fixed to the bottom of the water. An inlet 5 is located above its front wall, and an outlet pipe 4 is located below its rear wall. Several first water tower units 12 and second water tower units 13 are alternately connected above the bottom water tower unit 11. The first water tower units 12 and second water tower units 13 are square tubular structures. The right side wall of the first water tower unit 12 and the left side wall of the second water tower unit 13 are both provided with second sliding rails 7 for the sliding of the float 2. The inlet 5 is located above the front wall of the first water tower unit 12 and the second water tower unit 13. First sliding rails 6 are provided on both sides of the inlet 5 for the sliding of the baffle plate 3. The float 2 on the right side wall of the lowest first water tower unit 12 is connected to the... The bottom water tower unit 11 is connected to the baffle plate 3, and the float box 2 on the left side wall of the bottommost second water tower unit 13 is connected to the baffle plate 3 of the bottommost first water tower unit 12. The bottom water tower unit 11, the first water tower unit 12 and the second water tower unit 13 are connected by a connecting mechanism 9. The square water tower 1 of this utility model is composed of a bottom water tower unit 11 fixed to the bottom of the water and several first water tower units 12 and second water tower units 13 that are staggered above the bottom water tower unit 11. It is easy to transport and can set different numbers of first water tower units 12 and second water tower units 13 according to different reservoir depths to meet the surface water intake needs. The right side wall of the first water tower unit 12 is provided with a float box 2, and the left side wall of the second water tower unit 13 is provided with a float box 2, so that when the float box 2 drives the baffle plate 3 to move in the vertical direction, there will be no interference.

[0027] Furthermore, such as Figure 3 As shown, the connecting mechanism 9 includes a flange 91, an insertion frame 92, a sealing gasket 93, and connecting bolts 94. The flange 91 has a square frame structure, and its inner wall cross-section is equal to that of the inner wall of the square water tower 1. The outer wall of the flange 91 is provided with a plurality of bolt holes for the connecting bolts 94 to pass through. The inner wall of the flange 91 is connected to the insertion frame 92 for insertion into the inner wall of the square water tower 1. The connecting bolts 94 pass through the bolt holes on the flanges 91 on both sides and are connected to the connecting nuts. During installation, the insertion frame 92 is inserted into the end of the bottom water tower unit 11, the first water tower unit 12, or the second water tower unit 13. The flanges 91 on both sides are joined together, and the sealing gasket 93 is placed between the flanges 91. Then, the connecting bolts 94 are passed through the bolt holes on the flanges 91 and the sealing gasket and connected to the connecting nuts, thereby achieving a sealed connection between the bottom water tower unit 11, the first water tower unit 12, and the second water tower unit 13. Installation and disassembly are very convenient.

[0028] Furthermore, the first slide rail 6 includes a left first slide rail 61 and a right first slide rail 62. The left first slide rail 61 and the right first slide rail 62 are arranged in a square structure on both sides of the water inlet 5. The inner wall of the left first slide rail 61 and the right first slide rail 62 is provided with a first sliding groove 63 for the water baffle 3 to slide. When the water baffle 3 is located at the bottom of the first sliding groove 63, the float box 2 connected to the water baffle 3 is located at the bottom of the second slide rail 6, and the top of the water baffle 3 is located below the water inlet 5. The thickness of the water baffle 3 is equal to the width of the first sliding groove 63. When the water baffle 3 moves to the top of the first sliding groove 63, it can completely block the water inlet 5. When the water baffle 3 moves to the bottom of the first sliding groove 63, it can completely open the water inlet 5.

[0029] Furthermore, the second slide rail 7 includes a left second slide rail 71 and a right second slide rail 72. The inner walls of the left second slide rail 71 and the right second slide rail 72 are provided with second slide grooves 73. The float box 2 has a hollow square structure, and its inner walls are provided with sliders that can slide in conjunction with the second slide grooves 73. When the float box 2 is below the water surface, it rises due to buoyancy, and the slider slides upward along the second slide groove 73 until the baffle plate 3 moves to the top of the first slide groove 63 and completely blocks the water inlet 5 to form a limit. The float box 2 no longer floats. When the float box 2 is above the water surface, due to gravity, the float box 2 moves downward and drives the slider to slide to the second slide groove 73. At the same time, it drives the baffle plate 3 to slide along the first slide groove 63 to the bottom of the first slide groove 63, and fully opens the water inlet 5.

[0030] Furthermore, the bottom end of the float box 2 is connected to the front wall of the lower baffle plate 3 via a connecting rod 8. The connecting rod 8 includes a vertical rod 81, a horizontal rod 82, and a longitudinal rod 83. The top end of the vertical rod 81 is connected to the middle of the bottom end of the float box 2, the bottom end of the vertical rod 81 is perpendicularly connected to one end of the horizontal rod 82, the other end of the horizontal rod 82 is perpendicularly connected to one end of the longitudinal rod 83, and the other end of the longitudinal rod 83 is connected to the middle of the front wall of the baffle plate 3. This ensures that the float box 2 can stably drive the baffle plate 3 to move up and down without affecting the surface water entering through the inlet 5.

[0031] Furthermore, one end of the top of the first water tower unit 12 or the second water tower unit 13 is hinged to one end of the tower cover 15, and the other end of the top of the first water tower unit 12 or the second water tower unit 13 is connected to the tower cover 15 by a buckle 14.

[0032] Example: The longitudinal rod 83 is 1.7m long, the vertical rod 81 is 4.7m long, and the transverse rod 82 is 1.5m long. The water-blocking plate 3 is made of 1500mm*1600mm stainless steel plate with a thickness of 20mm, a density of approximately 7.85g / cm³, and weighs approximately 454.73kg. The float box 2 is 1700mm*600mm*1000mm in size and can provide 10kN of buoyancy, which is sufficient to ensure the buoyancy of the water-blocking plate 3 and the float box 2.

[0033] The device has multiple vertically arranged water inlets. Taking the second inlet (denoted as "Inlet B") as an example, the first inlet is denoted as "Inlet A", and the third inlet is denoted as "Inlet C", to illustrate the working process under different water level conditions:

[0034] Example 1: The water level is lower than the intermediate elevation of inlet B.

[0035] like Figure 4 The diagram shows the workflow under the water level conditions in Example 1.

[0036] Float box status: The float box (float box B) corresponding to inlet B is not submerged in water, and its buoyancy is zero. The water level does not completely cover float box A, and float box A floats on the water surface due to buoyancy.

[0037] Water baffle action: Under the influence of gravity, water baffle B slides down to the bottom slot of the slide rail, and water inlet B is fully opened. Float A drives the connecting rod to move upward, water baffle A begins to rise slowly, and water inlet A gradually closes.

[0038] Water intake status: Water inlet B is open and water can enter; if there is a water inlet A below, water inlet A is partially open and water enters through water inlet A. Water inlet C above is not in use.

[0039] Example 2. The water level is at the middle elevation of inlet B (partially covering inlet B).

[0040] like Figure 5 The diagram shows the workflow under the water level conditions in Example 2.

[0041] Float box status: The float box (float box B) corresponding to inlet B is not submerged in water, and the buoyancy is zero (the distance between the cover plate and the float box can be considered a fixed distance, approximately 5000mm. When the water level is at the mid-elevation of inlet B, there is still a distance between the float box and the water level). When the water level rises above the bottom of inlet B and completely covers float box A, float box A is completely submerged, and the buoyancy reaches its maximum value (10KN), pushing float box A up the slide rail to the top slot.

[0042] Water baffle action: Under the influence of gravity, water baffle B slides down to the bottom slot of the slide rail, and water inlet B is fully opened. Float A moves the connecting rod upwards, and water inlet A is fully closed.

[0043] Water intake status: Inlet B is open and partially filled with water; Inlet A is completely closed. Inlet C above is not in use.

[0044] Example 3. The water level completely covers the pontoon B, at which point the water level is higher than the top elevation of the inlet B.

[0045] like Figure 6 The diagram shows the workflow under the water level conditions in Example 3.

[0046] Float status: Float B is fully submerged, and the buoyancy reaches its maximum value (10KN), pushing Float B up the slide rail to the top slot.

[0047] Water baffle action: The connecting rod raises the water baffle B to the highest point, and the water inlet B is completely closed.

[0048] Water intake status: Inlet B is completely closed, and all inlets below inlet B are completely closed.

[0049] The water intake task is taken over by the upper water inlet C, which is opened and partially filled with water.

[0050] Example of dynamic water level change: When the water level continues to rise, from inlet A to B and then to C, the device sequentially closes inlets A and B, achieving continuous stratified water intake. The distance between the cover plate and the float box ensures that water can always be drawn from the pipeline regardless of water level changes.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
