Detailed Implementation

[0030] 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.

[0031] like Figure 1 As shown:

[0032] A water intake structure for water conservancy and hydropower projects includes a water pump 101, a pumping pipe 102 fixed at the input end of the water pump 101, and a water intake pipe 103 fixed at the output end of the water pump 101.

[0033] In this implementation plan: To solve the technical problems existing in the prior art, such as the background art disclosed above, "In order to ensure that the water inlet pipe can smoothly draw in water, a counterweight and a filter screen are set at the end of the water inlet pipe, so that the end of the water pipe can sink to the bottom of the water for easy water intake. However, due to the presence of silt in some ponds, if the end of the water pipe sinks into the silt, the silt may block the pipe during the water intake process, resulting in a small water volume, increased pressure on the water pump 101, and even damage to the water pump 101." In combination with the actual use, this problem is obviously a real and difficult problem to solve.

[0034] Furthermore:

[0035] like Figures 1-3 As shown:

[0036] Based on the above: multiple sets of support rods 111 are installed on one side of the water pump pipe 102;

[0037] Multiple sets of support rods 111 slide on the same movable plate 105, and a bent pipe 104 is installed on the movable plate 105, with one end of the bent pipe 104 fixedly connected to the water pumping pipe 102.

[0038] A connecting plate 106 and a floating plate 108 are respectively provided above and below the movable plate 105;

[0039] Two sets of slide rods 107 that can slide on the movable plate 105 are fixed between the connecting plate 106 and the floating plate 108. The movable plate 105 is provided with vertical guide holes that slide and fit with the slide rods 107.

[0040] A top plate 112 is provided between the tops of multiple sets of support rods 111;

[0041] Distance sensor 109 and distance sensor 210 are fixedly installed on the lower surface of the top plate 112, respectively.

[0042] A lifting mechanism 2 is installed on the top plate 112 to drive the moving plate 105 up and down;

[0043] The lifting mechanism 2 includes a stepper motor 201 fixed on the upper surface of the top plate 112, a take-up reel 202 fixedly installed at the output end of the stepper motor 201, and a rope 203 wound on the surface of the take-up reel 202.

[0044] A U-shaped frame 204 is fixedly installed on the upper surface of the movable plate 105. One end of the rope 203 passes through the top plate 112 and is fixed to the upper surface of the U-shaped frame 204. The other end of the rope 203 is fixed to the surface of the winding reel 202.

[0045] A square hole is provided on the surface of the top plate 112 at the position of the rope 203. A support plate is fixed on the upper surface of the top plate 112. One side of the winding reel 202 is rotatably connected to the support plate through a rotating shaft.

[0046] There are four sets of support rods 111, which are distributed at the four corners of the movable plate 105. The four corners of the movable plate 105 move on the support rods 111 through the through holes. A sliding sleeve is fixedly installed on the movable plate 105 at the through hole position to reduce the sliding friction between the sliding rod 107 and the movable plate 105.

[0047] Distance sensor 109 corresponds to connecting plate 106, and distance sensor 210 corresponds to the upper surface of moving plate 105.

[0048] In this implementation plan: When using the water diversion structure for water conservancy and hydropower projects, the support rod 111 is first inserted into the riverbank. At this time, the stepper motor 201 is started, which drives the winding reel 202 to rotate. The winding reel 202 releases the rope 203, which in turn drives the moving plate 105 to be released and moved downward, so that the moving plate 105 slides on multiple sets of support rods 111.

[0049] Until the movable plate 105 is located at the surface of the river, at which point the bottom end of the bent pipe 104 is submerged in the water;

[0050] Then the water pipe 103 is laid to the water diversion area, and then the water pump 101 is started to pump water through the bend pipe 104 into the pumping pipe 102, and then the water is transported through the water pipe 103.

[0051] As water is continuously pumped out, the water level in the pumping area continues to drop. Since the floating plate 108 can float on the water level, it remains floating on the water level as the water level drops. At this time, the floating plate 108 will drive the connecting plate 106 to move downward through the sliding rod 107.

[0052] The movable plate 105 is located at the position of the slide rod 107 and is equipped with a sliding sleeve, which reduces the friction between the slide rod 107 and the movable plate 105 and improves the smoothness of the slide rod 107's movement.

[0053] As the connecting plate 106 moves downward, the distance projected by the first distance sensor 109 onto the connecting plate 106 continuously increases. The first distance sensor 109 continuously monitors the distance change. When the control unit receives the signal of the increased distance, it sends a start signal to the stepper motor 201 to start driving the winding reel 202 to rotate and release the rope 203. At this time, the moving plate 105 slides downward on the surface of the support rod 111 due to its own weight. During the downward movement of the moving plate 105, the second distance sensor 110 monitors the distance change between the moving plate 105 and the fixed point in real time. The control unit adjusts the speed and direction of the stepper motor 201 according to the signal from the second distance sensor 110 to ensure that the moving plate 105... The downward movement distance of the moving plate 105 is the same as the distance change detected by the distance measuring sensor 109. When the distance measuring sensor 110 detects that the downward movement distance of the moving plate 105 is consistent with the distance change detected by the distance measuring sensor 109, the control unit will send a signal to the stepper motor 201 to stop it. During this process, as the water level continues to drop, the bottom end of the bend 104 is always in the water, which can maintain the pumping state. Thus, the bend 104 will not sink directly to the bottom of the water, thereby not being affected by silt, improving the pumping effect, avoiding blockage of the pumping pipe 102, the water inlet pipe 103 and the bend 104, reducing the pressure on the winding reel 202, improving the use effect of the device, and meeting the actual use requirements.

[0054] It should be noted that the stepper motor 201, the second distance sensor 110, and the first distance sensor 109 are powered by an external portable battery.

[0055] Furthermore;

[0056] In an optional embodiment, a weighted ring 205 is wound around the outer surface of the bend 104, and the weighted ring 205 is fixedly connected to the movable plate 105.

[0057] In this embodiment: a weight ring 205 is provided at the bottom of the movable plate 105, which increases the overall weight of the movable plate 105, thereby enabling the movable plate 105 to move better during the release process.

[0058] Furthermore;

[0059] In an optional embodiment, the support rod 111 may be provided with multiple sets of different length models and sizes;

[0060] A convenient locking mechanism 3 is installed on the top plate 112 to facilitate the connection and locking of the support rod 111;

[0061] The convenient locking mechanism 3 includes a mounting plate 301 fixed to the upper surface of the top plate 112 and arranged symmetrically, two sets of locking rods 302 sliding inside the mounting plate 301, and a spring 305 fixed between the two sets of locking rods 302;

[0062] The surface of the support rod 111 is provided with a locking groove 303 that is adapted to the locking rod 302. The locking rod 302 is inserted into the locking groove 303 of the support rod 111 for connecting and locking the top plate 112 and the support rod 111.

[0063] A circular hole is provided on the mounting plate 301. The locking rod 302 is slidably connected to the circular hole provided on the mounting plate 301. A square block 304 is fixed on the surface of the locking rod 302. A strip groove adapted to the square block 304 is provided on the upper surface of the mounting plate 301, and the strip groove is connected to the circular hole. The square block 304 and the mounting plate 301 are slidably connected through this strip groove. Insertion holes are provided at the four corners of the top plate 112, and the top end of the support rod 111 can be inserted into the insertion hole provided on the top plate 112.

[0064] In this embodiment: the support rod 111 can be provided with multiple sets of different length models and sizes, so that the support rod 111 of appropriate length can be set according to the depth of the riverbank;

[0065] During this process, when disassembling and replacing the support rod 111, the two sets of square blocks 304 slide towards each other, thereby compressing the spring 305 and moving the locking rod 302. This causes the locking rod 302 to disengage from the locking groove 303 of the support rod 111, thus releasing the connection between the top plate 112 and the support rod 111. This facilitates the replacement of the support rod 111 with a suitable length. When the suitable support rod 111 is inserted into each corner of the top plate 112, and the locking rod 302 corresponds to the locking groove 303 of the support rod 111, the square blocks 304 are released. At this time, the spring 305 rebounds and drives the locking rod 302 to be inserted into the locking groove 303, thereby realizing the installation of the support rod 111.

[0066] While the support rod 111 is being installed, it first passes through the four corner holes of the movable plate 105, then through the top plate 112, and is locked in place by the convenient locking mechanism 3.

[0067] It should be noted that the length of the support rod 111 can be from 1 meter to 5 meters.

[0068] The working principle and usage process of this utility model are as follows: When using this water diversion structure for water conservancy and hydropower projects, firstly, the support rods 111 are inserted into the riverbank. Then, the stepper motor 201 is started, which drives the winding reel 202 to rotate. The winding reel 202 releases the rope 203, causing the moving plate 105 to move downwards and slide on multiple sets of support rods 111 until it reaches the river surface. At this point, the bottom end of the bend pipe 104 is submerged in the water. Then, the water diversion pipe 103 is laid to the water diversion area, and subsequently, the water pump 101 is started, drawing water through the bend pipe 104 into the pumping station. Water is drawn into the water pipe 102 and transported through the water inlet pipe 103. As water is continuously pumped, the water level in the pumping area continuously decreases. Since the float plate 108 can float on the water level, it remains floating on the water level during the descent. At this time, the float plate 108 will drive the connecting plate 106 to move downward via the slide rod 107. The moving plate 105 is located at the position of the slide rod 107 and is equipped with a sliding sleeve, thereby reducing the friction between the slide rod 107 and the moving plate 105 and improving the smoothness of the slide rod 107's movement. At the same time as the connecting plate 106 moves downward, the distance sensor 109 projects onto the connecting plate 106. As the distance between the points increases, distance sensor 109 continuously monitors the distance change. When the control unit receives a signal indicating an increased distance, it sends a start signal to stepper motor 201 to drive the winding reel 202 to rotate and release the rope 203. At this time, the moving plate 105 slides downwards on the surface of support rod 111 due to its own weight. During the downward movement of the moving plate 105, distance sensor 110 monitors the distance change between the moving plate 105 and the fixed point in real time. The control unit adjusts the speed and direction of stepper motor 201 according to the signal from distance sensor 110 to ensure that the downward distance of the moving plate 105 is within the range detected by distance sensor 109. When the distance changes detected by the second distance sensor 110 are the same as the distance change detected by the first distance sensor 109, the control unit will send a signal to the stepper motor 201 to stop it. During this process, as the water level continues to drop, the bottom of the bend 104 is always in the water, which can maintain the pumping state. Thus, the bend 104 will not sink directly to the bottom of the water, and is not affected by silt, thereby improving the pumping effect, avoiding blockage of the pumping pipe 102, the water inlet pipe 103 and the bend 104, reducing the pressure on the winding reel 202, improving the use effect of the device, and meeting the actual use requirements.

[0069] During this process, when disassembling and replacing the support rod 111, the two sets of square blocks 304 slide towards each other, thereby compressing the spring 305 and moving the locking rod 302. This causes the locking rod 302 to disengage from the locking groove 303 of the support rod 111, thus releasing the connection between the top plate 112 and the support rod 111. This facilitates the replacement of the support rod 111 with a suitable length. When the suitable support rod 111 is inserted into each corner of the top plate 112, and the locking rod 302 corresponds to the locking groove 303 of the support rod 111, the square blocks 304 are then released. At this time, the spring 305 rebounds and causes the locking rod 302 to be inserted into the locking groove 303, thereby realizing the installation of the support rod 111.

[0070] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
