Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and in particular to a reservoir stratified water intake device. Background Art

[0002] Stratified water intake is a method of extracting water from fixed water intake structures with multiple water inlets at different water depths, which can be used to extract surface water of different depths and good water quality. Stratified water intake structures can be categorized into vertical shaft type, inclined culvert horizontal pipe type, and walled or watertight gate type.

[0003] After searching, Chinese patent number CN108396817A discloses a tower-type stratified water intake for a reservoir, comprising multiple water inlet pipes distributed from top to bottom within a tower body, with an operating room provided on top of the multiple water inlet pipes. The invention is characterized in that the operating room comprises multiple operating devices corresponding to the multiple water inlet pipes, each of which is provided with a valve; the driving shafts of the multiple operating devices are connected to embedded brackets passing through the floor of the operating room, and the valve stems of the embedded brackets are connected to the corresponding valves; the multiple operating devices drive the corresponding valves to move up and down by rotating the valve stems, thereby opening or closing the corresponding water inlet pipes;

[0004] In order to eliminate the need for workers to go down to the bottom of the tower to open and close the valves for stratified water intake, the above-mentioned public documents install a corresponding valve stem and operating device on each water intake valve. The operating device is uniformly installed inside the operating room, and the valve stem serves as the transmission component. Although this method solves the problem of workers having to go down to the bottom of the tower to operate, it also has some other problems. For example, when the valve stem is in operation, the longer the valve stem, the greater the torque it bears, and the more likely it is to be damaged and broken. At the same time, each valve corresponds to a separate operating device, which greatly increases the equipment cost.

[0037] See also Figure 1-8 The technical solution provided by the present invention specifically includes the following embodiments:

[0038] A reservoir stratified water intake device includes a water intake tower 1, wherein an operation room 11 and an equipment room 12 are provided inside the water intake tower 1, and the operation room 11 is located above the equipment room 12;

[0039] A water intake pipe group 2 is installed inside the equipment room 12. The water intake pipe group 2 consists of a connecting pipe 21, a water intake pipe 22, a valve 23, and a drain pipe 24. The number of the water intake pipes 22 and the number of the valves 23 are both set to three. The valve 23 is installed on the water intake pipe 22. The three valves 23 are respectively equipped with a valve stem 1 3, a valve stem 2 4, and a valve stem 3 5;

[0040] An operating mechanism is installed inside the operating chamber 11, and the operating mechanism is used to cooperate with valve stem 1 3, valve stem 2 4 and valve stem 3 5 to control the opening and closing of the three valves 23.

[0041] The three water intake pipes 22 are fixedly connected to the connecting pipe 21 from top to bottom, and the three water intake pipes 22 are staggered. The drain pipe 24 is fixedly connected to the bottom of the connecting pipe 21. The valve 23 and the drain pipe 24 are located inside the equipment room 12 and extend to the outside of the water intake tower 1.

[0042] The valve stem 1 3 includes a segmented stem 1 31;

[0043] The valve stem 2 4 is composed of a plurality of segmented rods 2 41 and a plurality of joints 1 42 , wherein the joints 1 42 are located between two adjacent segmented rods 2 41 ;

[0044] The valve stem 3 5 is composed of a plurality of segmented rods 3 51 and a plurality of joints 2 52 , wherein the joints 2 52 are located between two adjacent segmented rods 3 51 ;

[0045] The joint 2 52 includes 521 , and two mutually meshed 522 are connected inside the 521 . The segmented rod 3 51 passes through 521 and extends into the inside of 521 , and the two 522 are respectively fixedly connected to the ends of the two segmented rods 3 51 extending into the inside of 521 .

[0046] The segmented rod 1 31, the segmented rod 2 41 and the segmented rod 3 51 are of the same size, so when a segmented rod is damaged, it can be quickly replaced with a spare rod of the same model. At the same time, it also avoids the problem of difficulty in quickly replacing the entire long valve stem when it is damaged, as well as the high maintenance cost. The structures of the joint 1 42 and the joint 2 52 are completely the same, so the specific structure of the joint 1 42 will not be excessively described here.

[0047] The outer ends of the joint 1 42 and the joint 2 52 are fixedly connected to the fixing bracket 6, and the ends of the fixing bracket 6 are fixedly connected to the inner wall of the water intake tower 1 by bolts. The joint 1 42 and the joint 2 52 are fixedly connected to the inside of the equipment room 12 through the fixing bracket 6;

[0048] The fixed bracket 6 includes two support plates 61, and a plurality of cross beams 62 are fixedly connected between the two support plates 61. One end of the support plate 61 is fixedly connected to the outer end of 521, and the other end of the support plate 61 is fixedly connected to a seat plate 63. The seat plate 63 is fixedly connected to the inner wall of the equipment room 12 by bolts.

[0049] The fixing bracket 6 can fix the positions of the joint 1 42 and the joint 2 52 in the equipment room 12, thereby preventing the valve stem 2 4 and the valve stem 3 5 from shaking at the joints during transmission.

[0050] The operating mechanism is composed of a transmission mechanism 7 and a drive mechanism 8. The transmission mechanism 7 includes a U-shaped platform 71, which is fixedly connected to the inside of the operating room 11. Three connecting rods 73 are connected through the bottom of the U-shaped platform 71. The connecting rods 73 and the U-shaped platform 71 are movably connected. The connecting rods 73 are located inside the operating room 11 and extend to the inside of the equipment room 12. The bottom of the connecting rod 73 is fixedly connected to the top of the valve stem 3, the valve stem 2 4 and the valve stem 3 5 through a coupling. The top of the connecting rod 73 is fixedly connected to a large gear 74. The top of the U-shaped platform 71 is movably connected to three transmission rods 76. The transmission rod 76 is connected to a small gear 75, and the small gear 75 is meshed and connected to the front side of the large gear 74.

[0051] When the transmission rod 1 76 in the transmission mechanism rotates for transmission, the small gear 75 engages to drive the large gear 74 to rotate, which is more labor-saving. Then the large gear 74 rotates with the connecting rod 73, thereby rotating the corresponding valve stem 1 3, valve stem 2 4 or valve stem 3 5 to realize the opening and closing operation of driving the corresponding valve 23.

[0052] The top of the U-shaped platform 1 71 is fixedly connected to the U-shaped platform 2 72 , the transmission rod 1 76 passes through the U-shaped platform 2 72 and is movably connected to the U-shaped platform 2 72 , the top of the transmission rod 1 76 is fixedly connected to the worm gear 77 , and the worm gear 77 is located above the U-shaped platform 2 72 .

[0053] The driving mechanism 8 includes a second transmission rod 81, which is movably connected to the top of the second U-shaped platform 72 through a bearing seat. A plurality of worms 82 are fixedly connected to the second transmission rod 81, and the worms 82 are meshed and connected to the rear side of the worm wheel 77. The two ends of the second transmission rod 81 are respectively connected to an electric drive mechanism and a manual drive mechanism;

[0054] The electric drive mechanism includes a motor 83, which is fixedly connected to one side of the U-shaped platform 72. The output shaft of the motor 83 is fixedly connected to a gear 1 84. The outer end of the transmission rod 81 near the motor 83 is connected to a gear 2 85. The gear 1 84 and the gear 2 85 are meshed with each other.

[0055] The manual drive mechanism includes a shaft 86, which is movably connected to the top of the U-shaped platform 2 72 through a bearing seat, and the front side of the shaft 86 is fixedly connected to a rotating wheel 87, and the rear side of the shaft 86 is fixedly connected to a bevel gear 1 88. The outer end of the transmission rod 2 81 is connected to a bevel gear 2 89 on the side close to the rotating wheel 87, and the bevel gear 1 88 and the bevel gear 2 89 are engaged with each other.

[0056] When electric drive is required, the position of bevel gear 2 89 can be adjusted by connecting seat 3 93 so that bevel gear 2 89 cannot mesh with bevel gear 1 88. At this time, the manual drive mechanism is in a disconnected state and cannot be operated. Then the motor 83 is started, and the output shaft of the motor 83 drives the transmission rod 2 81 to rotate through the meshing of gear 1 84 and gear 2 85. The gear 2 85 is fixed to the transmission rod 2 81 through the connecting seat 2 92 to mesh with gear 1 84. When the transmission rod 2 81 rotates, it can drive the transmission through the meshing of the worm 82 and the worm wheel 77. When the rod 1 76 rotates, since only one small gear 75 can mesh with the corresponding large gear 74, the meshing transmission of the gear 2 85 and the large gear 74 can make the connecting rod 73 drive the corresponding valve stem 1 3, valve stem 2 4 or valve stem 3 5 to operate the corresponding valve 23 to open and close. On the contrary, when manually driven, it is only necessary to adjust the position of the gear 2 85 through the connecting seat 2 92 so that the electric drive mechanism is disconnected and cannot be operated, and the connecting seat 3 93 adjusts the position of the bevel gear 2 89 to mesh with the bevel gear 1 88. At this time, the hand-cranked wheel 87 can be driven

[0057] A connecting seat 1 91 is installed at the outer end of the transmission rod 1 76, and a connecting seat 2 92 and a connecting seat 3 93 are installed on the transmission rod 2 81. The connecting seat 2 92 and the connecting seat 3 93 correspond to the electric drive mechanism and the manual drive mechanism respectively, and the connecting seat 1 91, the connecting seat 2 92 and the connecting seat 3 93 are respectively used to adjust the positions of the pinion 75, the gear 2 85 and the bevel gear 2 89. Two sockets 1 761 are provided on the transmission rod 1 76, and two sockets 2 811 and two sockets 3 812 are provided on the transmission rod 2 81. The sockets 1 761, the sockets 2 811 and the sockets 3 812 correspond to the connecting seat 1 91, the connecting seat 2 92 and the connecting seat 3 93 respectively.

[0058] The connecting seat three 93 includes a sleeve 931, which is sleeved on the outer end of the transmission rod two 81. A positioning bolt 932 is connected to the front side of the sleeve 931. The sleeve 931 and the positioning bolt 932 are threadedly connected, and the end of the positioning bolt 932 extends to the inside of one of the socket three 812.

[0059] When the bevel gear 2 89 is engaged with the bevel gear 1 88, the sleeve 931 is fixed to the transmission rod 2 81 by the positioning bolt 932. At this time, the positioning bolt 932 is inserted into one of the three sockets 812 to achieve a fixed connection between the bevel gear 2 89 and the transmission rod 2 81. Conversely, when the bevel gear 1 88 and the bevel gear 2 89 do not need to be engaged, it is only necessary to move the sleeve 931 with the bevel gear 2 89 for a distance, and then insert the end of the positioning bolt 932 into the other socket 3 812, and then the bevel gear 2 89 Even if it rotates following the transmission rod 2 81, it cannot achieve meshing transmission with the bevel gear 1 88. The structure and function of the connecting seat 1 91 and the connecting seat 2 92 are the same as those of the connecting seat 3 93. The difference is that the connecting seat 1 91 and the connecting seat 2 92 are used to adjust the position of the small gear 75 and the gear 2 85, so that the small gear 75 and the large gear 74 can be meshed or disconnected, and the gear 2 85 and the gear 1 84 can be meshed or disconnected. Therefore, the specific structure of the connecting seat 1 91 and the connecting seat 2 92 will not be excessively described here.

[0060] The outer end of the transmission rod 76 is fixedly connected to a positioning ring 762, and the positioning ring 762 is located below the connecting seat 91. When the small gear 75 needs to be moved down to engage with the large gear 74, the connecting seat 91 can be moved down. At this time, the positioning ring 762 can block the connecting seat 91 so that the positioning bolt on it can be inserted into the corresponding socket 761. At the same time, the small gear 75 is also located in front of the large gear 74 to achieve engagement, and the positioning ring 762 can play a positioning role.

[0061] Working principle:

[0062] When taking water in layers, only one valve 23 needs to be opened at a time. The three valves 23 are opened and closed by valve stem 1 3, valve stem 2 4 and valve stem 3 5 respectively. Therefore, only one of valve stem 1 3, valve stem 2 4 and valve stem 3 5 needs to be rotated. During the specific operation, the small gear 75 on the other two transmission rods 1 76 can be moved up and fixed through the connecting seat 1 91, so that when the transmission mechanism 7 and the drive mechanism 8 are running, only one large gear 74 and the corresponding connecting rod 73 can be driven to rotate, and then electric or manual drive can be selected. When electric drive is required, the position of bevel gear 2 89 can be adjusted through the connecting seat 3 93 so that bevel gear 2 89 cannot mesh with bevel gear 1 88. At this time, the manual drive mechanism is in a disconnected state and cannot be operated. Then the motor 83 is started, and the output shaft of the motor 83 is moved through the gear 1 84 and the gear The meshing of wheel 2 85 drives transmission rod 2 81 to rotate, and gear 2 85 is fixed on transmission rod 2 81 through connecting seat 2 92 to mesh with gear 1 84. When transmission rod 2 81 rotates, transmission rod 1 76 can be driven to rotate through the meshing of worm 82 and worm wheel 77. At this time, since only one small gear 75 can mesh with the corresponding large gear 74, the meshing transmission of gear 2 85 and large gear 74 can enable connecting rod 73 to drive the corresponding valve stem 1 3, valve stem 2 4 or valve stem 3 5 to operate the corresponding valve 23 to open and close. On the contrary, when manually driven, it is only necessary to adjust the position of gear 2 85 through connecting seat 2 92 so that the electric drive mechanism is disconnected and cannot be operated, and connecting seat 3 93 adjusts the position of bevel gear 2 89 to mesh with bevel gear 1 88. At this time, the hand-cranked wheel 87 can be driven;

[0063] Valve stem 1 3 corresponds to the valve 23 at the highest position, and can therefore be directly driven through segmented stem 1 31. Valve stem 2 4 and valve stem 3 5 correspond to the valves 23 at the middle and lowest positions, respectively. When the valve 23 is opened and closed through valve stem 3 5, the adjacent ends of multiple segmented stems 3 51 in valve stem 3 5 are all driven through joint 2 52. In this way, a single segmented stem 3 51 is shorter in length and can withstand greater torque when under force without being easily deformed or broken.
