Description

Technical Field

[0001] This utility model relates to the field of salt field water level regulation technology, and more specifically, to a salt field water level regulation device. Background Technology

[0002] Water flow in salt pans is a core technological step in salt pan production, specifically referring to the process of brine flowing between different evaporation ponds. During water flow, the lost moisture within the salt pans needs to be replenished promptly to prevent soil compaction and reduced yield. Water level regulating devices are installed on the dams between adjacent evaporation ponds to adjust the flow direction or velocity of the brine. When the regulating device is open, brine from the evaporation pond with the higher water level flows through it to the evaporation pond with the lower water level. Furthermore, the opening of the regulating device can be adjusted according to the water level difference between the two evaporation ponds to control the brine flow rate.

[0003] In the prior art, Chinese patent CN218969923U discloses a drainage device for salt lakes and salt fields, which includes a gantry, a gate, and a chain hoist. The gantry consists of a top crossbeam and channel steel welded vertically downwards to both ends of the crossbeam, forming a gate. Each channel steel has a groove on its inner side, and the gate's two ends are respectively embedded in two of these grooves. The gate can move up and down relative to the gantry to adjust the flow rate at the gate. After the gate is in position, the chain hoist secures its position. However, with this drainage device, adjusting the flow rate at the gate requires manual adjustment by workers, resulting in high labor intensity. Utility Model Content

[0004] The main purpose of this utility model is to provide a salt field water level regulating device to solve the problem of high labor intensity caused by manually adjusting the position of the gate to regulate the flow of the gate in the existing technology.

[0006] Furthermore, an anti-detachment plate is provided at the ends of the two gates that are far apart from each other. The anti-detachment plate is movably installed in the corresponding receiving groove and cooperates with the upper and lower groove walls of the receiving groove.

[0007] Furthermore, a guide hole is provided on the side of the receiving groove and on one of the anti-detachment plates. The axial direction of the guide hole is the same as the moving direction of the anti-detachment plate. A guide rod is provided on the side of the receiving groove and on the other of the anti-detachment plates. The guide rod is movably inserted into the guide hole and guides the guide hole.

[0008] Further, the first driving component includes: a first driving member, disposed on a mounting base, the first driving member having a first output shaft; a driving rod, rotatably disposed on the mounting base, the driving rod extending along the distribution direction of the two gates, the driving rod including a first screw section and a second screw section, the thread direction of the first screw section being opposite to the thread direction of the second screw section, one gate being threadedly connected to the first screw section, the other gate being threadedly connected to the second screw section, the first screw section and the second screw section respectively forming two first output ends; and a transmission assembly, respectively connected to the first output shaft and the driving rod, the first driving member driving the driving rod to rotate through the transmission assembly.

[0009] Furthermore, the transmission assembly includes: a first transmission wheel, which is disposed on and coaxial with the first output shaft; a second transmission wheel, which is disposed on and coaxial with the drive rod; and a toothed belt, which is sleeved on the first transmission wheel and the second transmission wheel, and the toothed belt meshes with the first transmission wheel and the second transmission wheel respectively.

[0010] Furthermore, the salt field water level regulating device also includes: a first water level detection element, which is installed on the first side of the mounting base; a second water level detection element, which is installed on the second side of the mounting base, with the first and second sides of the mounting base arranged opposite to each other along the through direction of the gate; and a control system, which is installed on the mounting base. The first water level detection element, the second water level detection element, and the first driving component are electrically connected to the control system, and the first driving component controls the operation of the two gates according to the water level information detected by the first and second water level detection elements.

[0011] Furthermore, the salt field water level regulating device also includes an auxiliary water volume regulating component, which includes a water pipe and a bidirectional water pump. The bidirectional water pump is installed on the water pipe, and the water pipe is installed on the mounting base. The first opening of the water pipe is located on the first side of the mounting base, and the second opening of the water pipe is located on the second side of the mounting base. The first and second sides of the mounting base are arranged opposite to each other along the through direction of the gate.

[0012] Furthermore, the salt field water level regulating device also includes: a photovoltaic module, including a photovoltaic panel, which is pivotally mounted on the top of the mounting base; and a second drive member, which is mounted on the mounting base and has a second output end, which is driven to connect with the photovoltaic panel to adjust the tilt angle of the photovoltaic panel relative to the horizontal plane.

The ends of the two photovoltaic panels that are far apart from each other are respectively hinged to the top of the mounting base. The second driving component has two second output ends, which are respectively driven and connected to the two photovoltaic panels. Alternatively, the salt field water level regulating device also includes a reflector, which is set on the mounting base. The reflector is located on one side of the photovoltaic panel, and the reflector and the photovoltaic panel are sequentially distributed along the perpendicular direction of the pivot axis of the photovoltaic panel. The reflector is inclined and the reflective surface of the reflector faces the photovoltaic panel.

[0015] By applying the technical solution of this utility model, the first driving component can automatically drive the two gates to move, thereby realizing automatic regulation of the gate flow rate without manual operation, reducing the labor intensity of workers and improving work efficiency. Furthermore, in the prior art, the gantry forms the gate, and the gates typically move vertically relative to the gantry to regulate the gate flow rate. This configuration results in a relatively high overall height of the gantry, requiring a complex device to fix the gantry to the dam body of the salt field to ensure its stability. In contrast, the gates in this solution are laterally movable relative to the mounting base, eliminating the need for an excessively high mounting base. This reduces the installation cost and difficulty of fixing the mounting base to the salt field dam body and also improves the stability of the mounting base's fixation to the dam body.

[0031] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 3As shown, this utility model embodiment provides a salt field water level regulating device, which includes: a mounting base 10, which is provided with a gate 101 and a receiving groove 102 communicating with the gate 101. There are two receiving grooves 102, which are located on the left and right sides of the gate 101 respectively; two gates 20, which are arranged one-to-one with the two receiving grooves 102. The gates 20 are movably inserted into the corresponding receiving grooves 102 in the lateral direction relative to the mounting base 10 to close or open the gate 101. The two gates 20 move closer or further away from each other to regulate the flow rate of the gate 101; a first driving member 30, which is arranged on the mounting base 10. The first driving member 30 has two first output ends, which are arranged one-to-one with the two gates 20. The first output ends are drivenly connected to the gates 20 to drive the gates 20 to move.

[0033] By applying the technical solution of this utility model, the first driving component 30 can automatically drive the two gates 20 to move, thereby realizing automatic regulation of the flow rate at the gate 101 without manual operation, reducing the labor intensity of workers and improving work efficiency. Furthermore, in the prior art, the gantry forms the gate, and the gates typically move vertically relative to the gantry to regulate the flow rate at the gate. This configuration results in a relatively high overall height of the gantry, requiring a complex device to fix the gantry to the dam body of the salt field to ensure its stability. In this solution, the gates 20 are movably positioned laterally relative to the mounting base 10, eliminating the need for an excessively high mounting base 10. This reduces the installation cost and difficulty of fixing the mounting base 10 to the salt field dam body and also improves the stability of the mounting base 10 fixed to the salt field dam body.

[0034] It is understood that the salt field includes multiple evaporation ponds enclosed by multiple dams. A flow channel for brine is provided on the dam between two adjacent evaporation ponds. The mounting base 10 is set at the flow channel and fixed on the dam. The two ends of the gate 101 are connected to the two evaporation ponds respectively. The moving direction of the gate 20 is the same as the extension direction of the corresponding dam.

[0035] In this embodiment, both gates 20 are rectangular plate structures. A guide groove is provided at the bottom and top of the gate 101. The top of each gate 20 is movably inserted into the guide groove at the top, and the bottom of each gate 20 is movably disposed in the guide groove at the bottom.

[0036] Furthermore, each of the two gates 20 is provided with an anti-detachment plate 21 at its far end. The anti-detachment plate 21 is movably disposed within the corresponding receiving groove 102 and cooperates with the upper and lower groove walls of the receiving groove 102. This arrangement can prevent the possibility of the gate 20 detaching from the corresponding receiving groove 102 during the process of closing the gate 101, and prevent abnormal displacement of the gate 20 due to external factors (such as wind force and water flow pressure), thereby improving the reliability of the device operation.

[0037] Furthermore, a guide hole 211 is provided on the side of the receiving groove 102 and one of the anti-detachment plates 21. The axial direction of the guide hole 211 is the same as the moving direction of the anti-detachment plate 21. A guide rod 13 is provided on the side of the receiving groove 102 and the other of the anti-detachment plates 21. The guide rod 13 is movably inserted into the guide hole 211 and guides and cooperates with the guide hole 211.

[0038] In this embodiment, one end of the guide rod 13 is disposed on the groove wall of the receiving groove 102 at the end away from the gate 101, and the other end of the guide rod 13 extends in the direction of the gate 101. The guide hole 211 penetrates the anti-detachment plate 21 along the moving direction of the anti-detachment plate 21.

[0039] It is understandable that there are freshwater boats and freshwater pipes in the salt fields. In order to reduce the accumulation of salt scale on the guide rod 13, the staff can periodically flush the container tank 102 with freshwater pipes.

[0040] Specifically, the first driving component 30 includes: a first driving member 31, disposed on the mounting base 10, the first driving member 31 having a first output shaft; a driving rod 32, rotatably disposed on the mounting base 10, the driving rod 32 extending along the distribution direction of the two gates 20, the driving rod 32 including a first screw section 321 and a second screw section 322, the direction of the thread of the first screw section 321 being opposite to the direction of the thread of the second screw section 322, one gate 20 being threadedly connected to the first screw section 321, the other gate 20 being threadedly connected to the second screw section 322, the first screw section 321 and the second screw section 322 respectively forming two first output ends; and a transmission assembly 33, respectively connected to the first output shaft and the driving rod 32, the first driving member 31 driving the driving rod 32 to rotate through the transmission assembly 33.

[0041] In this design, the first driving component 31 is the power source for the first driving component 30, providing power for the rotation of the driving rod 32. After the first driving component 31 is activated, the first output shaft begins to rotate, transmitting power to the driving rod 32 via the transmission assembly 33. The driving rod 32 rotates along with the first output shaft. The gate 20 threadedly connected to the first screw section 321 and the other gate 20 threadedly connected to the second screw section 322 move synchronously towards each other or synchronously in opposite directions. When the two gates 20 move towards each other, the flow rate at the gate 101 decreases; when the two gates 20 move in opposite directions, the flow rate at the gate 101 increases.

[0042] Specifically, the transmission assembly 33 includes: a first transmission wheel 331, mounted on and coaxial with the first output shaft; a second transmission wheel 332, mounted on and coaxial with the drive rod 32; and a toothed belt 333, sleeved on the first transmission wheel 331 and the second transmission wheel 332, with the toothed belt 333 meshing with both the first transmission wheel 331 and the second transmission wheel 332. After the first drive component 31 is activated, the first transmission wheel 331 on the first output shaft begins to rotate, driving the toothed belt 333 to move synchronously through meshing with it. Since the other side of the toothed belt 333 meshes with the second transmission wheel 332, it drives the second transmission wheel 332 to rotate, and the rotation of the second transmission wheel 332 causes the drive rod 32 to rotate. The arrangement of the first transmission wheel 331, the second transmission wheel 332, and the toothed belt 333 improves the smoothness of the power transmission process, enhances the stability of the drive rod 32's rotation, and improves the stability of the gate 20's movement.

[0043] Specifically, to reduce the possibility of brine splashing onto the first drive member 30, the first drive member 30 is located entirely at the top of the mounting base 10. The first screw section 321 and the second screw section 322 of the drive rod 32 are respectively threaded to the top ends of the two anti-detachment plates 21. The first transmission wheel 331 is located above the drive rod 32.

[0044] Furthermore, the salt field water level regulating device also includes: a first water level detection element 41, which is disposed on the first side of the mounting base 10; a second water level detection element 42, which is disposed on the second side of the mounting base 10, with the first and second sides of the mounting base 10 being arranged opposite each other along the through direction of the gate 101; and a control system, which is disposed on the mounting base 10. The first water level detection element 41, the second water level detection element 42, and the first driving component 30 are electrically connected to the control system, and the first driving component 30 controls the operation of the two gates 20 according to the water level information detected by the first water level detection element 41 and the second water level detection element 42.

[0045] The first water level detection element 41 and the second water level detection element 42 can be ultrasonic water level sensors, radar water level sensors, pressure sensors, or float-type water level sensors, etc. They can monitor the water level of their respective evaporation tanks in real time and convert the water level information into electrical signals, which are then transmitted to the control system. This part is prior art and will not be described in detail here.

[0046] In this embodiment of the solution, the first driving component 31 is electrically connected to the control system.

[0047] Specifically, the control of the first driving component 31 can be achieved through a program setting. When the difference between the water level of the corresponding evaporation pool detected by the first water level detection component 41 and the water level of the corresponding evaporation pool detected by the second water level detection component 42 exceeds a first preset value, the control system transmits a signal to the first driving component 31, and the first driving component 30 drives the two gates 20 to move away from each other by a preset distance to increase the flow rate of the gate 101. When the difference between the water level of the corresponding evaporation pool detected by the first water level detection component 41 and the water level of the corresponding evaporation pool detected by the second water level detection component 42 is less than a second preset value, the control system recognizes that the water level is approaching equilibrium or near an ideal state. At this time, it is necessary to reduce the flow rate at the gate 101 to avoid increased energy consumption or reverse water level imbalance caused by over-adjustment. The control system transmits a signal to the first driving component 31, and the first driving component 30 drives the two gates 20 to move closer to each other by a preset distance to reduce the flow rate of the gate 101.

[0048] Furthermore, the top of the mounting base 10 in this solution is also provided with a control box 11, the first drive unit 31 and the control system are both located inside the control box 11, and a display screen 111 is provided on the outer wall of the control box 11, and the display screen 111 is electrically connected to the control system.

[0049] The control box 11 includes a box body and a door. The box body has a side opening, and the door is hinged to the box body to close or open the opening. This design facilitates the maintenance of the components inside the control box 11.

[0050] Furthermore, the salt field water level regulating device also includes an auxiliary water volume regulating component 50. The auxiliary water volume regulating component 50 includes a water pipe 51 and a bidirectional water pump 52. The bidirectional water pump 52 is mounted on the water pipe 51, which is mounted on the mounting base 10. The first opening 511 of the water pipe 51 is located on the first side of the mounting base 10, and the second opening 512 of the water pipe 51 is located on the second side of the mounting base 10. The first and second sides of the mounting base 10 are arranged opposite to each other along the through direction of the gate 101. In this embodiment, the bidirectional water pump 52 is electrically connected to the control system.

[0051] In this design, the first opening 511 and the second opening 512 of the water pipe 51 are aligned with the first and second evaporation pools, respectively. A bidirectional water pump 52 is installed on the water pipe 51, capable of pumping brine in both directions: from the first evaporation pool to the second evaporation pool, and vice versa. This design allows the salt field water level regulating device to not only control the natural flow of brine through the gate 20, but also to forcibly adjust the flow direction and flow rate of the brine when necessary through the bidirectional water pump 52, thus improving the flexibility and response speed of water level regulation.

[0052] In this embodiment of the solution, the bidirectional water pump 52 is electrically connected to the control system.

[0053] like Figure 4 As shown, this solution also includes interconnected sleeves 53 and filter screens 54, with the filter screen 54 located at one end of the sleeve 53 along its axial direction. A sleeve 53 is threadedly connected to both the first opening 511 and the second opening 512 of the water pipe 51. This arrangement allows a filter screen 54 to be installed at both the first opening 511 and the second opening 512. During the flow of brine through the water pipe 51, the filter screen 54 filters the brine, reducing or preventing impurities from clogging the water pipe 51 and improving drainage smoothness.

[0054] Specifically, the bidirectional water pump 52 can be controlled through a program. When the difference between the water level detected by the first water level detector 41 and the water level detected by the second water level detector 42 exceeds a third preset value (where the third preset value is greater than the first preset value), the control system determines that the current water level has exceeded the normal adjustment range. The control system will then start the bidirectional water pump 52 and determine its working direction based on the water level, i.e., pumping water from the side with the higher water level to the side with the lower water level to accelerate the restoration of water level balance.

[0055] like Figures 1 to 3 As shown, the salt field water level regulating device also includes: a photovoltaic module, including a photovoltaic panel 60, which is pivotally mounted on the top of the mounting base 10. Specifically, the photovoltaic panel 60 is pivotally mounted on the top of the control box 11; and a second drive member 70, mounted on the mounting base 10, having a second output end connected to the photovoltaic panel 60 to adjust the tilt angle of the photovoltaic panel 60 relative to the horizontal plane. The salt field receives ample sunlight. By installing the photovoltaic panel 60 on the top of the mounting base 10, the photovoltaic panel 60 can continuously receive high-intensity sunlight, thereby stably generating electricity. The pivotal mounting of the photovoltaic panel 60 on the top of the mounting base 10 allows the photovoltaic panel 60 to adjust its tilt angle according to the position and movement trajectory of the sun, specifically by driving the photovoltaic panel 60 to rotate.

[0056] In this embodiment of the scheme, the pivot axis of the photovoltaic panel 60 extends in the horizontal direction so that the angle between the photovoltaic panel 60 and the horizontal plane changes when the photovoltaic panel 60 rotates.

[0057] A light sensor can be installed inside the photovoltaic panel 60 to monitor the light intensity and direction in real time. The light sensor and the second driving component 70 are electrically connected to the control system. The control system analyzes the information detected by the light sensor to determine whether the photovoltaic panel 60 needs to be adjusted in order to maximize the efficiency of the photovoltaic panel 60 in receiving solar energy. If the control system determines that the photovoltaic panel 60 needs to be adjusted, it sends a control command to the second driving component 70, which drives the photovoltaic panel 60 to rotate. This part is prior art and will not be described in detail here.

[0058] The photovoltaic modules generate electrical energy which is stored in an energy storage device, which then supplies power to the first drive unit 31, the first water level detection unit 41, the second water level detection unit 42, the control system, and the bidirectional water pump 52.

[0059] Furthermore, the second driving component 70 includes a second driving member 71, a slider 72, and a transmission rod 73. The second driving member 71 is disposed at the top of the mounting base 10. The slider 72 is movably disposed along a pivot axis perpendicular to the photovoltaic panel 60. The second driving member 71 is drivenly connected to the slider 72. One end of the transmission rod 73 is hinged to the slider 72, and the other end is hinged to the photovoltaic panel 60. The transmission rod 73 forms a second output end. The control system is electrically connected to the second driving member 71.

[0060] Specifically, when the second drive unit 71 operates according to the instructions of the control system, it drives the slider 72 to move. During the movement of the slider 72, the end of the transmission rod 73 that is hinged to the slider 72 moves with the slider 72. The end of the transmission rod 73 that is away from the slider 72 rises or falls to adjust the angle between the photovoltaic panel 60 and the horizontal plane.

[0061] Furthermore, the salt field water level regulating device also includes a reflector 80, which is mounted on the mounting base 10. The reflector 80 is located on one side of the photovoltaic panel 60, and the reflector 80 and the photovoltaic panel 60 are distributed sequentially along the perpendicular direction of the pivot axis of the photovoltaic panel 60. The reflector 80 is inclined, with its reflective surface facing the photovoltaic panel 60. The arrangement of the reflector 80 enhances the light intensity received by the photovoltaic panel 60 and improves its energy conversion efficiency when the angle of sunlight hitting the photovoltaic panel 60 is unfavorable.

[0062] Understandably, the installation locations of the photovoltaic panel 60 and the reflector 80 can be optimized based on the geographical location and seasonal changes of the salt field, so that the reflector 80 can reflect sunlight onto the photovoltaic panel 60 as much as possible, thereby increasing the energy collection capacity of the photovoltaic panel 60.

[0063] In this embodiment, two photovoltaic panels 60 are provided, arranged sequentially along the horizontal direction. The ends of the two photovoltaic panels 60 that are far apart from each other are hinged to the top of the mounting base 10. The second driving member 70 has two second output ends, which are respectively drivenly connected to the two photovoltaic panels 60. Two reflectors 80 are provided, located on the far apart sides of the two photovoltaic panels 60, with the tops of the two reflectors 80 tilted in the far apart direction.

[0064] Specifically, in this scheme, the second driving component 70 includes two sliders 72 and two transmission rods 73, with each of the two transmission rods 73 corresponding to one of the two photovoltaic panels 60. The second driving component 71 is a motor with two output shafts. A first screw is fixedly connected to one of the output shafts of the second driving component 71, and a second screw is fixedly connected to the other output shaft. The threads on the first and second screws have opposite directions of rotation. The first and second screws are distributed along the distribution direction of the two photovoltaic panels 60, with the first screw located below one of the photovoltaic panels 60 and the second screw located below the other photovoltaic panel 60. The first screw is threadedly connected to one of the sliders 72, which is hinged to the end of the corresponding transmission rod 73 away from the photovoltaic panel 60. The second screw is threadedly connected to the other slider 72, which is hinged to the end of the corresponding transmission rod 73 away from the photovoltaic panel 60.

[0065] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0066] 1. The first driving component 30 can automatically drive the two gates 20 to move, thereby realizing automatic adjustment of the flow rate of the gate 101 without manual operation, reducing the labor intensity of the staff and improving work efficiency.

[0067] 2. In this scheme, the gate 20 is movably set in the lateral direction relative to the mounting base 10, so the height of the mounting base 10 does not need to be set too high. This can reduce the installation cost and difficulty of fixing the mounting base 10 to the salt field dam body, and also improve the stability of fixing the mounting base 10 to the salt field dam body.

[0068] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
