Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically to a water quality improvement treatment system for basin ecological governance. Background Technique

[0002] In basin ecological governance, the water quality condition is crucial for the stability and health of the entire ecosystem. Good water quality constructs a suitable habitat environment for various aquatic organisms. For example, fish, shellfish, plankton, and aquatic plants all rely on clean water bodies to intake oxygen, search for food, and build breeding places. By improving water quality, the toxic effects of pollutants on aquatic organisms can be effectively reduced, the biological mortality rate can be decreased, the reproduction and growth of aquatic organisms can be strongly promoted, thereby maintaining the biodiversity of aquatic organisms, enriching the species composition of the ecosystem, and ensuring the stable operation of the ecological hydrological system. At the same time, the increase in dissolved oxygen content in the water body due to water quality improvement creates favorable conditions for the growth and reproduction of aerobic microorganisms. These microorganisms can decompose and transform organic pollutants in the water into harmless substances such as carbon dioxide and water.

[0003] Currently, water quality improvement in the process of basin ecological governance is mainly achieved through three methods: physical, chemical, and biological. Among them, chemical improvement means include adding coagulants to the water, such as polyaluminum chloride, aluminum sulfate, etc., to cause colloidal particles and tiny suspended impurities in the water to aggregate into larger flocs for precipitation or filtration removal; it also includes adding specific chemical agents to form insoluble precipitates of certain dissolved pollutants in the water for removal.

[0004] Chemical improvement means usually rely on a water quality improvement treatment system installed below the river water layer to add chemical agents. However, traditional water quality improvement treatment systems have significant limitations and are difficult to meet the complex requirements of water quality improvement in basin ecological governance. These systems usually set multiple medicine boxes with different types of agents below the river water layer. Due to the different consumption rates of different agents, there is often a situation where the agent in one medicine box is completely consumed by the impact of the water flow, while the agents in other medicine boxes still have stocks. When secondary agent addition operations are required, due to the limitations of the design of traditional water quality improvement treatment systems, when removing the empty medicine box, the other medicine boxes with remaining stocks will also be taken out together. This operation method lacks the flexibility to separately remove the empty medicine box, resulting in the unconsumed agents in the other medicine boxes with remaining stocks being forced to be exposed to the air. The agents are exposed to the air for a long time, which is extremely likely to cause unnecessary volatilization and loss, greatly reducing the effective utilization rate of the agents, and thus reducing the water quality improvement efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a water quality improvement treatment system for basin ecological governance, so as to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: A water quality improvement treatment system for basin ecological governance, including a bracket, further including:

[0007] A main transmission shaft rotatably installed on the bracket and having a first turntable fixed thereon;

[0008] A secondary transmission shaft rotatably and slidably installed on the bracket and having a second turntable fixed thereon that engages with the first turntable. The rotation of the first turntable drives the rotation of the second turntable. A spline rod capable of key connection with a spline sleeve and a main end face gear capable of meshing with a driven end face gear are fixed on the second turntable. A spline sleeve connecting rod with a first gear fixed thereon is fixed on the spline sleeve, and a driven end face gear connecting rod with a second gear fixed thereon is fixed on the driven end face gear;

[0009] It further includes a third turntable rotatably installed on the bracket and capable of engaging with the second turntable, a third gear meshing with the first gear, and a fourth gear meshing with the second gear. When the second turntable rotates, it drives the rotation of the third turntable. Medicine boxes are fixed on the third turntable, the second gear, and the second gear, and when rotating, they drive the medicine boxes thereon to rotate upward;

[0010] When the secondary transmission shaft slides, it can successively disengage the second turntable from the third turntable, key-connect the spline rod with the spline sleeve, and mesh the main end face gear with the driven end face gear.

[0011] Preferably, a plurality of first push rods are fixedly arranged along the circumferential direction on one side surface of the first turntable. The first push rods can be in contact connection with a push plate fixed on the second turntable, and the push plate can be in contact with a second push rod fixed on the third turntable. The rotation of the first turntable makes the second turntable rotate through the first push rods, and the rotation of the second turntable drives the rotation of the third turntable through the transmission of the push plate.

[0012] Preferably, the third turntable is rotatably arranged on a first lifting plate. The first lifting plate is rotatably arranged on the main transmission shaft. The first lifting plate is axially relatively fixed to the main transmission shaft, and the first lifting plate is provided with a notch corresponding to the secondary transmission shaft.

[0013] Preferably, the spline sleeve connecting rod is rotatably installed on a first mounting plate and passes through the first mounting plate. The first mounting plate is rotatably arranged on the main transmission shaft. The first mounting plate is axially relatively fixed to the main transmission shaft. The spline sleeve connecting rod rotates on the first mounting plate under the driving action of the spline sleeve, and while rotating, the spline sleeve connecting rod drives the first gear to rotate.

[0014] Preferably, the second gear is rotatably installed on a second lifting plate. The second lifting plate is rotatably arranged on the main transmission shaft. The second lifting plate is axially relatively fixed to the main transmission shaft. The second gear rotates relative to the second lifting plate under the driving of the first gear.

[0015] Preferably, the driven end face gear connecting rod is rotatably mounted on the second mounting plate, the second mounting plate is rotatably mounted on the main transmission shaft, the second mounting plate is axially fixed relative to the main transmission shaft, and the main end face gear and the driven end face gear rotate to drive the driven end face gear connecting rod to rotate on the second mounting plate.

[0016] Preferably, the fourth gear is rotatably arranged on the third hoisting plate, the third hoisting plate is rotatably arranged on the main transmission shaft, the third hoisting plate is axially fixed relative to the main transmission shaft, and the fourth gear rotates relative to the third hoisting plate under the drive of the second gear.

[0017] Preferably, one end of the main transmission shaft is fixedly connected to the output end of the driving motor, the driving motor is fixedly arranged on the bracket, and the driving motor drives the main transmission shaft to rotate.

[0018] Preferably, the third turntable, the third gear and the fourth gear are axially fixedly connected to the central axis rod, both ends of the central axis rod are fixedly connected to one end of each of the medicine box connecting rods, the other ends of the medicine box connecting rods are fixedly connected to the chassis, at least one medicine box is fixedly arranged on the chassis, and the surface of the medicine box is provided with a water inlet, a water outlet and a medicine discharging port. While the third turntable, the third gear and the fourth gear are respectively rotating, the central axis rod will rotate accordingly. The rotation of the central axis rod drives the medicine box connecting rods and the chassis to make a circular rotation around the axes of the third turntable, the third gear and the fourth gear, and the chassis drives the medicine box to rotate upward while rotating.

[0019] Preferably, a hydraulic push rod is fixedly arranged on the bracket, the piston rod end of the hydraulic push rod is rotatably connected to one end of the auxiliary transmission shaft and is axially fixedly connected. When the piston rod end of the hydraulic push rod extends, it pushes the auxiliary transmission shaft to slide relative to the bracket. And because the hydraulic push rod is rotatably connected to the auxiliary transmission shaft, the auxiliary transmission shaft will not drive the hydraulic push rod to rotate when rotating.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: By sliding the auxiliary transmission shaft relative to the bracket by different distances, the second turntable can be disengaged from the third turntable, the spline rod can be key-connected to the spline sleeve, and the main end face gear can be engaged with the driven end face gear in sequence, so that the three groups of medicine boxes can respectively obtain separate kinetic energy inputs. The specific kinetic energy input process is as follows:

[0021] First of all, the first turntable of the main transmission shaft rotatably mounted on the bracket functions as the total kinetic energy input. The second turntable engaged with the first turntable is used as the kinetic energy input for the rotation of the first group of medicine boxes. The second turntable is engaged with the third turntable in the initial state, and the second turntable and the first turntable always remain engaged. The second turntable drives the third turntable to rotate under the drive of the first turntable, and the rotation of the third turntable can drive the first group of medicine boxes thereon to rotate upward separately to realize the separate removal of the first group of medicine boxes.

[0022] The spline sleeve and spline shaft assembly on the second turntable serve as the driving components for the second group of medicine boxes. After the auxiliary transmission shaft slides a certain distance, the second turntable fixed on the auxiliary transmission shaft disengages from the third turntable, and the first group of medicine boxes loses the kinetic energy input. The spline sleeve and spline shaft form a key connection, and the spline shaft drives the spline sleeve to rotate. The spline sleeve drives the first gear connected to it to rotate. The first gear meshes with the third gear fixed with the second group of medicine boxes. The rotation of the first gear drives the third gear to rotate, and the rotation of the third gear drives the second group of medicine boxes on it to rotate upward, thereby realizing the separate removal of the second group of medicine boxes.

[0023] The driven end face gear and the main end face gear on the second turntable serve as the driving components for the third group of medicine boxes. After the auxiliary transmission shaft continues to slide a certain distance, the spline sleeve and spline shaft lose the key connection, and the second group of medicine boxes also loses the kinetic energy input. The movement of the second turntable drives the main end face gear on it to move and thus mesh with the driven end face gear. The rotation of the second turntable drives the main end face gear to rotate, the rotation of the main end face gear drives the driven end face gear to rotate, the rotation of the driven end face gear drives the second gear fixed on it to rotate, the rotation of the second gear drives the fourth gear meshing with it to rotate, and the rotation of the fourth gear drives the third group of medicine boxes on it to rotate upward, thereby realizing the separate removal of the third group of medicine boxes.

[0024] Through the above mechanism, according to the usage conditions of the medicines in different medicine boxes, a certain group of medicine boxes can be separately rotated upward so as to be able to move from below the river water layer to above the river water layer, facilitating manual addition of medicines into the empty medicine boxes that have moved to above the river water layer, and avoiding the situation where other medicine boxes are also moved to above the river water layer when a group of medicine boxes needs to be added with medicines, greatly improving the flexibility of medicine addition and the efficiency of water quality improvement treatment.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-7 , the present invention provides a technical solution:

[0035] As Figure 1 shown, in order to realize the independent extraction and control of each medicine box, a water quality improvement treatment system for basin ecological governance is proposed, including a bracket 1. In this embodiment, there are two brackets 1 arranged oppositely, and the bracket 1 can be placed on the riverbed of the river. It also includes a control component for independently controlling the medicine box.

[0036] The control component includes a main transmission shaft 101 rotatably mounted on the bracket 1. One end of the main transmission shaft 101 is fixedly connected to the output end of the driving motor 102, and the driving motor 102 is fixedly mounted on the bracket 1. A first turntable 103 is coaxially and fixedly arranged on the main transmission shaft 101. A plurality of first shifting rods 104 are fixedly connected to the surface of the first turntable 103. The surface of the first shifting rod 104 can be in contact connection with the surface of the shifting plate 2021 on the second turntable 202. The second turntable 202 is rotatably mounted on the bracket 1 and its axis is parallel to the axis of the first turntable 103. The shifting plate 2021 is fixedly arranged on the second turntable 202. In this embodiment, a plurality of first shifting rods 104 are provided, and the plurality of first shifting rods 104 are fixedly arranged on the first turntable 103 in the circumferential direction. The axis of the first shifting rod 104 is parallel to the axis of the first turntable 103. In this embodiment, a plurality of shifting plates 2021 are provided, and the plurality of shifting plates 2021 are fixedly arranged on the second turntable 202. The shifting plate 2021 extends along the radial direction of the second turntable 202. When the first shifting rod 104 rotates, it can exert a thrust on the shifting plate 2021, thereby causing the second turntable 202 to rotate accordingly.

[0037] The second turntable 202 is coaxially and fixedly arranged on the surface of the auxiliary transmission shaft 201. One end of the auxiliary transmission shaft 201 is rotatably and slidably arranged on a bracket 1. The shifting plate 2021 on the second turntable 202 can also be in contact connection with the second shifting rod 204 fixedly arranged on the third turntable 203. The length of the second shifting rod 204 is less than the length of the first shifting rod 104. In this embodiment, a plurality of second shifting rods 204 are provided and the plurality of second shifting rods 204 are fixedly arranged on the third turntable 203 in the circumferential direction. The second shifting rod 204 is parallel to the first shifting rod 104. The third turntable 203 is rotatably arranged on the first lifting plate 205. The first lifting plate 205 is rotatably arranged on the main transmission shaft 101. The first lifting plate 205 is axially relatively fixed to the main transmission shaft 101. The first lifting plate 205 serves to connect and mount the third turntable 203. The first lifting plate 205 is provided with a notch corresponding to the auxiliary transmission shaft 201, and the auxiliary transmission shaft 201 passes through this notch. This notch can prevent the first lifting plate 205 from interfering with the position of the auxiliary transmission shaft 201.

[0038] In order to realize the sliding of the auxiliary transmission shaft 201, a hydraulic push rod 6 is fixedly arranged on the bracket 1. The piston rod end of the hydraulic push rod 6 is rotatably connected to one end of the auxiliary transmission shaft 201, and the piston rod end of the hydraulic push rod 6 is axially fixedly connected to one end of the auxiliary transmission shaft 201. The hydraulic push rod 6 is fixedly arranged on one side of the bracket 1. The telescopic movement of the piston rod of the hydraulic push rod 6 drives the auxiliary transmission shaft 201 to slide relative to the bracket 1.

[0039] As Figure 3As shown in the figure, a set of medicine box connection components are fixedly connected to the axis of the third turntable 203. The medicine box connection components include an axis rod 701 fixed at the axis of the third turntable 203. One end of each of the two medicine box connecting rods 702 is fixedly connected to both ends of the axis rod 701. The other ends of the two medicine box connecting rods 702 are fixedly connected to the bottom frame 703. A first group of medicine boxes 704 are fixedly arranged on the bottom frame 703. In this embodiment, the number of medicine boxes in each group is two. Of course, the number of individual medicine boxes in each group can be set according to needs. The medicine box 704 is a hollow cuboid. An inlet 7042, an outlet 7043 and a medicine dispensing port 7041 are arranged on the surface of the medicine box 704 (shown in Figure 7 ). Water flows into the medicine box 704 through the inlet 7042, is mixed with the medicine in the medicine box 704, and then flows out through the outlet 7043. The medicine in the medicine box 704 can be added through the medicine dispensing port 7041. The length of the medicine box connecting rod 702 can be selected according to the depth of the river water. The deeper the river water, the longer the length of the medicine box connecting rod 702.

[0040] When it is necessary to move the first group of medicine boxes 704 out of the water surface alone, the driving motor 102 provides energy for the rotation of the main transmission shaft 101. The main transmission shaft 101 rotates, and the first turntable 103 coaxially arranged with it rotates. The first lever 104 on the first turntable 103 exerts a thrust on the dial 2021 on the second turntable 202, thereby pushing the second turntable 202 to rotate. While the second turntable 202 rotates, the dials 2021 on the second turntable 202 that rotate to the side away from the first lever 104 come into contact with the second levers 204 on the third turntable 203 one by one and exert a thrust on them, so that the third turntable 203 rotates. An axis rod 701 is fixedly connected to the axis of the third turntable 203, so the axis rod 701 will rotate accordingly, and its rotation direction is the same as that of the third turntable 203. The axis rod 701 drives the medicine box connecting rod 702 and the bottom frame 703 to rotate. The medicine boxes 704 on the bottom frame 703 will gradually rotate around the third turntable 203 with the axis rod 701 as the center until the first group of medicine boxes 704 are moved out of the water surface. During this process, the position of the first lifting plate 205 does not move.

[0041] As Figures 2-5 shown, one side of the second turntable 202 is fixedly connected to one end of a spline rod connecting rod 301. The other end of the spline rod connecting rod 301 is fixedly connected to a spline rod 302. The inside of the spline rod 302 is hollow. The spline rod 302 can be key-connected to a spline sleeve 303. The spline sleeve 303 is fixedly connected to a spline sleeve connecting rod 304 (shown in Figure 1 、 4One end (in the figure), the spline sleeve connecting rod 304 passes through the first mounting plate 308 and is rotatably connected to the first mounting plate 308. The first mounting plate 308 is used to mount the spline sleeve connecting rod 304. The first mounting plate 308 is rotatably arranged on the main transmission shaft 101, and the first mounting plate 308 is axially fixed relative to the main transmission shaft 101. The other end of the spline sleeve connecting rod 304 is fixedly connected to the first gear 305 (shown in Figure 1 in the figure). The spline sleeve connecting rod 304 is a hollow tube. The spline sleeve connecting rod 304 is sleeved on the surface of the driven end face gear connecting rod 404 (shown in Figure 2 , 4 in the figure) and is rotatably connected to the driven end face gear connecting rod 404. The first gear 305 can be meshed and connected with the third gear 306 (shown in Figure 1 in the figure). The third gear 306 is rotatably mounted on the second lifting plate 307 (the second lifting plate 307 is shown in Figure 6 in the figure). The second lifting plate 307 functions to mount the third gear 306. The second lifting plate 307 is rotatably arranged on the main transmission shaft 101, and the second lifting plate 307 is axially fixed relative to the main transmission shaft 101. A second set of medicine box connection components is fixed at the center of the third gear 306. The central rod 701 of the medicine box connection component is fixedly connected to the center of the third gear 306. One end of each of the two medicine box connecting rods 702 is fixedly connected to both ends of the central rod 701. The other end of the medicine box connecting rod 702 is fixedly connected to the chassis 703. The second set of medicine boxes 704 is fixedly arranged on the chassis 703. The number of the second set of medicine boxes 704 is also two.

[0042] When it is necessary to separately move the second group of medicine boxes 704 out of the water surface, extend the piston rod end of the hydraulic push rod 6, and then push the secondary transmission shaft 201 to move towards the spline sleeve 303. The movement of the secondary transmission shaft 201 drives the second turntable 202 to move in the same direction. Since the length of the first lever 104 is longer than that of the second lever 204, at this time, the surface of the first lever 104 still maintains a contact connection with the surface of the dial plate 2021 on the second turntable 202. However, the dial plate 2021 on the second turntable 202 loses connection with the second lever 204 on the third turntable 203, and the third turntable 203 does not rotate. The secondary transmission shaft 201 drives the second turntable 202 to move, and then drives the spline rod connecting rod 301 and the spline rod 302 to move. Therefore, as the secondary transmission shaft 201 moves, the spline rod 302 is key-connected to the spline sleeve 303. The driving motor 102 supplies energy for the rotation of the main transmission shaft 101. The first lever 104 on the first turntable 103 exerts a thrust on the dial plate 2021 on the second turntable 202, and then drives the second turntable 202 to rotate. The second turntable 202 drives the spline rod connecting rod 301 and the spline rod 302 to rotate, and then drives the spline sleeve 303 to rotate. The kinetic energy on the spline sleeve 303 is transmitted to the first gear 305 through the spline sleeve connecting rod 304. The first gear 305 drives the third gear 306 to rotate. The third gear 306 is fixedly connected with an axle rod 701 at its center. Therefore, the axle rod 701 will rotate accordingly, and its rotation direction is the same as that of the third gear 306. The axle rod 701 drives the medicine box connecting rod 702 and the chassis 703 to rotate. The medicine box 704 on the chassis 703 will gradually rotate around the third gear 306 with the axle rod 701 as the center until the second group of medicine boxes 704 move out of the water surface. At this time, the first group and the third group of medicine boxes 704 do not move. During this process, the second lifting plate 307 does not move in position.

[0043] As Figures 2-5As shown, one side of the second turntable 202 is fixedly connected to one end of the first driven rod 401. The other end of the first driven rod 401 is fixedly connected to the main end face gear 402. The main end face gear 402 can be meshed and connected with the driven end face gear 403. The main end face gear 402 and the driven end face gear 403 are located in the inner cavity of the spline rod 302 and the spline sleeve 303. One end of the driven end face gear connecting rod 404 is fixedly connected to the driven end face gear 403. The driven end face gear connecting rod 404 is rotatably installed on the second mounting plate 410. The second mounting plate 410 is used to install the driven end face gear connecting rod 404. The driven end face gear connecting rod 404 passes through the second mounting plate 410. The second mounting plate 410 is rotatably installed on the main transmission shaft 101. The second mounting plate 410 is axially fixedly connected to the main transmission shaft 101. The other end of the driven end face gear connecting rod 404 is fixedly connected to the second gear 405. The second gear 405 is meshed and connected with the fourth gear 406. The fourth gear 406 is rotatably arranged on the third hoisting plate 408. The third hoisting plate 408 is rotatably arranged on the main transmission shaft 101. The third hoisting plate 408 is axially relatively fixed to the main transmission shaft 101. The third hoisting plate 408 is used to install the fourth gear 406. The central axis of the fourth gear 406 is fixedly connected to the third group of medicine box connection components. Both ends of the central axis rod 701 of the medicine box connection components are fixedly connected to one end of a medicine box connecting rod 702. The other end of the medicine box connecting rod 702 is fixedly connected to the chassis 703. The third group of medicine boxes 704 are fixedly arranged on the chassis 703. The number of the third group of medicine boxes 704 is also two.

[0044] When it is necessary to move the third group of medicine boxes 704 out of the water surface separately, extend the piston rod end of the hydraulic push rod 6 to push the secondary transmission shaft 201 to move towards the driven end face gear 403. During the movement, the spline rod 302 is in key connection with the spline sleeve 303 in the initial state. However, as the secondary transmission shaft 201 continues to move, the spline rod 302 gradually disengages from the key connection state with the spline sleeve 303 (the spline rod 302 is still located within the spline sleeve 303, but the spline rod 302 and the spline sleeve 303 are no longer in a key connection state, and the rotation of the spline rod 302 will not drive the spline sleeve 303 and the spline sleeve connecting rod 304 to rotate, and thus will not drive the spline sleeve connecting rod 304 and the first gear 305 to rotate). The movement of the secondary transmission shaft 201 drives the second turntable 202, the first driven rod 401 and the main end face gear 402 to move. When the main end face gear 402 moves to be meshed and connected with the driven end face gear 403, the spline rod connecting rod 301 extends into the spline sleeve 303, and the spline sleeve 303 cannot obtain kinetic energy input, so the spline sleeve 303 will not rotate. At this time, the first group of medicine boxes 704 and the second group of medicine boxes 704 have no kinetic energy input, and neither the first group of medicine boxes 704 nor the second group of medicine boxes 704 will move. However, the first dial rod 104 on the first turntable 103 can still be in contact connection with the dial plate 2021 on the second turntable 202, that is, the rotation of the first turntable 103 can drive the second turntable 202 to rotate. Therefore, under the drive of the drive motor 102, the rotation of the main transmission shaft 101 drives the secondary transmission shaft 201 to rotate through the first turntable 103 and the second turntable 202. The rotation of the secondary transmission shaft 201 drives the main end face gear 402 to rotate through the second turntable 202 and the first driven rod 401, and the driven end face gear 403 rotates accordingly. The driven end face gear 403 drives the driven end face gear connecting rod 404 and the second gear 405 to rotate. The second gear 405 is meshed and connected with the fourth gear 406, so the fourth gear 406 rotates. The axis of the fourth gear 406 is fixedly connected to the axis rod 701, so the axis rod 701 will rotate accordingly, and its rotation direction is the same as that of the fourth gear 406. The axis rod 701 drives the medicine box connecting rod 702 and the chassis 703 to rotate, and the medicine boxes 704 on the chassis 703 will gradually rotate around the fourth gear 406 with the axis rod 701 as the center until the third group of medicine boxes 704 move out of the water surface.

[0045] The medicine in the medicine box 704 adopts existing water purification chemical solid medicines, such as sodium hydroxide, lime, polyaluminum chloride, etc.

[0046] Working principle:

[0047] First, the three groups of medicine boxes 704 are in the water during operation. The secondary transmission shaft 201 is located above the water surface. Under the impact of water flow, water enters the medicine box 704 through the water inlet 7042 and flows out of the medicine box 704 through the water outlet 7043. The medicine in the medicine box 704 is impacted by the water, so consumption will occur. Due to external water flow and the nature of the medicine itself, the consumption rates of the medicine in the three groups of medicine boxes 704 are different. Therefore, it is necessary to manually refill the three groups of medicine boxes 704 with medicine.

[0048] When it is necessary to move the first group of medicine boxes 704 out of the water surface separately, the driving motor 102 supplies energy for the rotation of the main transmission shaft 101. The main transmission shaft 101 rotates, and the first turntable 103 coaxially arranged with it rotates. The first lever 104 on the first turntable 103 exerts a thrust on the dial 2021 on the second turntable 202, thereby pushing the second turntable 202 to rotate. While the second turntable 202 rotates, the dial 2021 on the second turntable 202 that rotates to the side away from the first lever 104 contacts the second lever 204 on the third turntable 203 one by one and exerts a thrust on it, so that the third turntable 203 rotates. The axis rod 701 is fixedly connected to the center of the third turntable 203, so the axis rod 701 will rotate accordingly, and its rotation direction is the same as that of the third turntable 203. The axis rod 701 drives the medicine box connecting rod 702 and the chassis 703 to rotate. The medicine box 704 on the chassis 703 will gradually rotate around the third turntable 203 with the axis rod 701 as the center until the first group of medicine boxes 704 is moved out of the water surface. During this process, the position of the first lifting plate 205 does not move. After the first group of medicine boxes 704 is moved out of the water surface, the operator puts new solid medicine into the medicine box 704 through the medicine loading port 7041.

[0049] When it is necessary to move the second group of medicine boxes 704 out of the water surface separately, extend the piston rod end of the hydraulic push rod 6, and then push the secondary transmission shaft 201 to move towards the spline sleeve 303. The movement of the secondary transmission shaft 201 drives the second turntable 202 to move in the same direction. Since the length of the first lever 104 is longer than that of the second lever 204, at this time, the surface of the first lever 104 still maintains a contact connection with the surface of the dial plate 2021 on the second turntable 202. However, the dial plate 2021 on the second turntable 202 loses connection with the second lever 204 on the third turntable 203, and the third turntable 203 does not rotate. The secondary transmission shaft 201 drives the second turntable 202 to move, and then drives the spline rod connecting rod 301 and the spline rod 302 to move. Therefore, as the secondary transmission shaft 201 moves, the spline rod 302 is key-connected to the spline sleeve 303. The drive motor 102 provides energy for the rotation of the main transmission shaft 101. The first lever 104 on the first turntable 103 exerts a thrust on the dial plate 2021 on the second turntable 202, and then pushes the second turntable 202 to rotate. The second turntable 202 drives the spline rod connecting rod 301 and the spline rod 302 to rotate, and then drives the spline sleeve 303 to rotate. The kinetic energy on the spline sleeve 303 is transmitted to the first gear 305 through the spline sleeve connecting rod 304. The first gear 305 drives the third gear 306 to rotate. The center of the third gear 306 is fixedly connected with a center rod 701. Therefore, the center rod 701 will rotate accordingly, and its rotation direction is the same as that of the third gear 306. The center rod 701 drives the medicine box connecting rod 702 and the chassis 703 to rotate. The medicine box 704 on the chassis 703 will gradually rotate around the third gear 306 with the center rod 701 as the center until the second group of medicine boxes 704 moves out of the water surface. At this time, the first group and the third group of medicine boxes 704 do not move. During this process, the second lifting plate 307 does not move in position. Workers put new solid medicines into the medicine box 704 through the medicine feeding port 7041.

[0050] When it is necessary to move the third group of medicine boxes 704 out of the water surface alone, extend the piston rod end of the hydraulic push rod 6 to push the secondary transmission shaft 201 to move towards the driven end face gear 403. During the movement, the spline rod 302 is in key connection with the spline sleeve 303 in the initial state. However, as the secondary transmission shaft 201 continues to move, the spline rod 302 gradually disengages from the key connection state with the spline sleeve 303 (the spline rod 302 is still located inside the spline sleeve 303, but the spline rod 302 and the spline sleeve 303 are no longer in the key connection state, and the rotation of the spline rod 302 will not drive the spline sleeve 303 and the spline sleeve connecting rod 304 to rotate, and thus will not drive the spline sleeve connecting rod 304 and the first gear 305 to rotate). The movement of the secondary transmission shaft 201 drives the second turntable 202, the first driven rod 401 and the main end face gear 402 to move. When the main end face gear 402 moves to be meshed and connected with the driven end face gear 403, the spline rod connecting rod 301 extends into the spline sleeve 303, and the spline sleeve 303 cannot obtain kinetic energy input, so the spline sleeve 303 will not rotate. At this time, the first group of medicine boxes 704 and the second group of medicine boxes 704 have no kinetic energy input, and neither the first group of medicine boxes 704 nor the second group of medicine boxes 704 will move. However, the first shift lever 104 on the first turntable 103 can still be in contact connection with the shift plate 2021 on the second turntable 202, that is, the rotation of the first turntable 103 can drive the second turntable 202 to rotate. Therefore, under the drive of the drive motor 102, the rotation of the main transmission shaft 101 drives the secondary transmission shaft 201 to rotate through the first turntable 103 and the second turntable 202. The rotation of the secondary transmission shaft 201 drives the main end face gear 402 to rotate through the second turntable 202 and the first driven rod 401, and the driven end face gear 403 rotates accordingly. The driven end face gear 403 drives the driven end face gear connecting rod 404 and the second gear 405 to rotate. The second gear 405 is meshed and connected with the fourth gear 406, so the fourth gear 406 rotates. The axis of the fourth gear 406 is fixedly connected to the axis rod 701, so the axis rod 701 will rotate accordingly, and its rotation direction is the same as that of the fourth gear 406. The axis rod 701 drives the medicine box connecting rod 702 and the chassis 703 to rotate, and the medicine box 704 on the chassis 703 will gradually rotate around the fourth gear 406 with the axis rod 701 as the center until the third group of medicine boxes 704 move out of the water surface.
