Description

Technical Field

[0001] The utility model relates to the technical field of canal maintenance, and particularly relates to an electric turbulence generation system. Background Technique

[0002] Canals are widely used as hydraulic structures for water diversion and conveyance. However, canals in cold regions in the northern part of China often freeze partially or even completely due to extremely low winter temperatures, which greatly affects the water diversion and conveyance efficiency, and may even cause water to overflow and lead to engineering accidents.

[0003] CN202220630605.9 has disclosed a solar-powered boat for canal anti-freezing, which relates to the technical field of canal anti-freezing. Its structure includes a base, a sliding rod fixedly connected to the upper surface of the base, a hull movably connected to the circumferential surface of the sliding rod, an integrated box fixedly connected to the upper end of the hull, an anti-freezing control module is arranged inside the integrated box, and a mechanical anti-freezing mechanism is arranged on the inner wall of the hull. The mechanical anti-freezing mechanism includes a motor, a helical gear II fixedly connected to the surface of the output shaft of the motor, a helical gear I meshed with the surface of the helical gear II, a rotating shaft fixedly connected to the surface of the helical gear I, the circumferential surface of the rotating shaft penetrates and is rotatably connected to the side wall surface of the hull, a rotating gear disk is fixedly connected to the surface of the rotating shaft, a fixed block is fixedly connected to the inner wall of the hull, and the circumferential surface of the rotating shaft penetrates and is rotatably connected to the surface of the fixed block. The mechanical anti-freezing mechanism is symmetrically structured with the helical gear II as the center. This device can increase the fluidity of water in the canal, reduce the possibility of canal freezing, and thus ensure the normal operation of the canal.

[0004] However, the above-mentioned solar-powered boat for canal anti-freezing is fixedly installed and used in the canal, so it is only suitable for smaller canals. In some larger canals, such as the diversion open channel built on the side of the project during the construction of a canal water conservancy project, due to the need to convey the original designed water volume of the canal, it is usually wider. In such larger and wider canals, or canals with a longer freezing area, if the above-mentioned solar-powered boat for canal anti-freezing with a fixed structure is used, it is difficult to achieve a good anti-freezing effect. If the number of devices is increased to ensure the anti-freezing effect, the implementation cost will increase sharply. Once local freezing occurs in the diversion open channel, it is easy to cause water to overflow and form a canal engineering accident.

[0005] Therefore, how to design a canal anti-freezing system suitable for wide water surfaces and with low implementation costs has become a problem to be considered and solved by those skilled in the art. Summary of the Utility Model

[0006] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide an electric turbulence generation system that can effectively prevent canals from freezing and is suitable for wide canals.

[0007] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] An electric turbulence generating system, including a turbulence generating boat, is characterized in that it includes a horizontal guide rod erected above the water surface of the water channel along a set path. A slider is slidably sleeved on the horizontal guide rod. A connecting frame is fixedly arranged on the slider. A lifting rod device is installed on the connecting frame. The lifting rod device has a vertically arranged and vertically liftable lifting slide rod. The lower end of the lifting slide rod is installed with the turbulence generating boat arranged along the direction of the horizontal guide rod. A self-driven turbulence generating device is installed on the turbulence generating boat.

[0009] In this way, when the system equipment is not in use, the turbulence generating boat is retracted upward by the lifting rod device and lifted out of the water so as not to interfere with the flow of the water channel. When the water temperature in the water channel is too low and approaches zero degree, the lifting rod device can be controlled to lower the lifting slide rod so that the turbulence generating boat floats on the water surface in the water channel. Then, the self-driven turbulence generating device is started to control the turbulence generating boat to travel back and forth along the horizontal guide rod on the water surface of the water channel to generate turbulence. The generated turbulence can well prevent the water channel from freezing and ensure the smooth flow of the water channel in low-temperature weather or at night. Therefore, the above system equipment is particularly suitable for anti-freezing use of water channels with a wide water surface or a long freezing area, and its overall implementation cost is relatively low.

[0010] Further, rollers are arranged on the inner side surface of the slider and are in rolling fit with the horizontal guide rod.

[0011] In this way, the smoothness of the movement of the slider on the horizontal guide rail is better improved.

[0012] Further, both ends of the horizontal guide rod are fixedly and suspendedly supported above the water surface of the water channel by fixed supports. In this way, it is better to ensure sufficient overhead clearance.

[0013] Further, the connecting frame is integrally U-shaped. One end of its upper part is fixed on the slider. The lifting rod device includes a vertically arranged sleeve fixed on the lower part of the connecting frame and a lifting motor fixed on the other end of the upper part of the connecting frame. The lifting motor is horizontally arranged and a winch is installed at the front end of the main shaft and is disposed right above the sleeve. A cable is wound on the winch. The lifting slide rod is slidably installed in the sleeve and its upper end is fixedly connected with the cable.

[0014] In this way, by driving the winch to rotate forward or backward by the lifting motor, the turbulence generating boat can be stably lifted out of the water and lowered into the water through the cable and the lifting slide rod.

[0015] Further, the lifting motor is a self-locking motor. In this way, it is convenient to realize self-locking after the turbulence generating boat is lifted in place.

[0016] Furthermore, the self-driven turbulence generating device includes a rotating shaft disposed on the turbulence generating ship along the width direction of the ship. Both ends of the rotating shaft penetrate through the ship and a ring of impellers are installed outside the ship on each side. The impellers at the lower part of the rotating shaft are submerged below the water surface, and the rotating shaft is connected to a driving motor installed on the ship through a transmission belt.

[0017] In this way, by driving the impellers to rotate through the driving motor, while generating waves to create turbulence, the turbulence generating ship is driven to move forward. It has the advantages of simple structure, good wave generation and turbulence generation while being self-driven. Additionally, during implementation, storage batteries can be respectively provided on the turbulence generating ship and the connecting frame to supply power to their respective motors, or power can be supplied by connecting to an external power source through wires, which will not be elaborated here.

[0018] Furthermore, rectangular openings are further provided on the blades of the impellers, and multiple elastic bandages are arranged in parallel within the openings. Each elastic bandage shields the opening as a whole and has different elastic forces.

[0019] In this way, when the impellers rotate to push the water flow, due to the different elastic forces of the elastic bandages, different gap distances can be pressed out between the bandages by the water pressure for the water flow to pass through. Therefore, a more chaotic turbulent flow effect can be created, greatly improving its turbulence generation and anti-freezing effects. During implementation, the elastic bandages can be made of rubber skins with different elastic forces.

[0020] Furthermore, it further includes a control center. On each side of the lower end of the slider, a distance sensor is provided. The distance sensor is connected to the control center, and the control center is connected to the driving motor.

[0021] In this way, when the distance sensor detects that the turbulence generating ship is approaching the shore during movement, it gives a signal, and the control center controls the driving motor to switch between forward and reverse rotations, realizing the automatic control of the turbulence generating ship to travel back and forth along the set path.

[0022] Furthermore, a temperature control detection module is also provided in the water channel. The temperature control detection module is connected to the control center, and the control center is connected to the lifting motor.

[0023] In this way, when the temperature control detection module automatically detects that the water temperature in the water channel has dropped to the required level, it automatically controls the lifting motor to start through the control center, realizing the automatic detection and opening / closing control of the system equipment.

[0024] As an option, the temperature control detection module includes a detection float. The detection float is vertically slidably installed through a detection vertical rod standing in the water channel, and a temperature sensor is provided at a position below the water surface on the detection float and is connected to the control center.

[0025] In this way, the temperature sensor is not affected by water flow and water level fluctuations and can automatically detect the water temperature to achieve automatic sensing control.

[0026] As an alternative, the temperature control detection module includes a detection float floating on the water surface of the water channel. The detection float has an upward mounting groove, and an elastic airbag is arranged in the mounting groove. The upper surface of the elastic airbag has a horizontally arranged piston. A piston rod is fixedly arranged upward at the upper end of the piston. A power brush head is fixedly arranged horizontally at the upper end of the piston rod. The outer end of the power brush head can be slid up and down and is fitted on a vertically arranged conductive strip. One end of the conductive strip and the power brush head form a variable resistor and are connected to a temperature detection circuit. The temperature detection circuit is connected to the control center; a phase change gas is arranged in the elastic airbag.

[0027] In this way, when the water flow temperature in the water channel is lower than the preset temperature, the phase change gas changes from a gaseous state to a liquid state, the volume shrinks and drives the power brush head to slide down, changing the resistance of the variable resistor, and then relying on the temperature detection circuit to realize the detection of the temperature; and then relying on the control center to realize the corresponding control operation. Therefore, the temperature detection module with this structure can realize real-time temperature monitoring and feedback, with sensitive and reliable response, simple structure, and convenient implementation. When specifically implemented, the temperature detection circuit is a prior art, that is, it can convert the resistance change of the variable resistor into an electrical signal, and will not be elaborated here specifically.

[0028] Further, a first phase change gas and a second phase change gas are mixed and arranged in the elastic airbag. The phase change temperature of the first phase change gas is 0 - 5 °C, and the phase change temperature of the second phase change gas is -10 - 0 °C.

[0029] In this way, by controlling and adjusting the ratio of the two phase change gases, the control temperature of the flow disturbance prevention device can be adjusted within a temperature range, and the temperature value can be adjusted according to needs.

[0030] Further, a vertical sliding hole is vertically penetrated through the detection float and is slidably sleeved on a positioning pile vertically arranged in the water channel. In this way, the positioning of the temperature control detection module can be better realized.

[0031] In summary, the present invention is suitable for implementation and application in a relatively wide water channel, can well prevent the water channel from freezing in winter or on colder nights, has a good anti-freezing effect and a low overall implementation cost; when implemented and applied in a diversion open channel, it can well prevent the diversion open channel from affecting the water conveyance efficiency due to local freezing, and even cause the water flow to overflow and trigger engineering accidents.

[0035] The following further elaborates on the present utility model in conjunction with the detailed implementation manners.

[0036] Embodiment: An electric turbulence generation system, refer to Figure 1-2 , which includes a horizontal guide rod 1 erected above the water surface of the water channel along a set path. A slider 2 is slidably sleeved on the horizontal guide rod 1. A connecting frame 3 is fixedly arranged on the slider 2. An elevating rod device is installed on the connecting frame 3. The elevating rod device has a vertically arranged and vertically movable elevating slide rod 4. A turbulence generation boat 5 arranged along the direction of the horizontal guide rod is installed at the lower end of the elevating slide rod 4. A self-driven turbulence generation device is installed on the turbulence generation boat 5.

[0037] In this way, when the system equipment is not in use, the turbulence generation boat is retracted upward by the elevating rod device and separated from the water surface so as not to interfere with the flow of the water channel. When the water temperature in the water channel is too low and approaches zero degree, the elevating rod device can be controlled to lower the elevating slide rod, so that the turbulence generation boat floats on the water surface in the water channel. Then, the self-driven turbulence generation device is started to control the turbulence generation boat to travel back and forth on the water surface of the water channel along the horizontal guide rod to generate turbulence. The generated turbulence can well prevent the water channel from freezing and ensure the smooth flow of the water channel in low-temperature weather or at night. Therefore, the above system equipment is particularly suitable for anti-freezing use of water channels with a wide water surface.

[0038] Wherein, rollers are arranged on the inner side surface of the slider 2 and are in rolling cooperation with the horizontal guide rod 1. In this way, the smoothness of the movement of the slider on the horizontal guide rail is better improved.

[0039] Wherein, both ends of the horizontal guide rod 1 are fixedly and suspendingly supported above the water surface of the water channel by fixed supports 6. In this way, it is better to ensure sufficient overhead clearance.

The elevating rod device includes a vertically arranged sleeve 7 fixed to the lower part of the connecting frame and an elevating motor 8 fixedly installed at the other end of the upper part of the connecting frame 3. The elevating motor 8 is horizontally arranged and a winch 9 facing the sleeve 7 is installed at the front end of the main shaft. A cable 10 is wound around the winch 9. The elevating slide rod is slidably installed in the sleeve and the upper end is fixedly connected to the cable.

[0041] In this way, by driving the winch to rotate forward or backward by the elevating motor, the turbulence generation boat can be stably lifted out of the water surface and lowered into the water surface through the cable and the elevating slide rod.

[0042] Wherein, the elevating motor 8 is a self-locking motor. In this way, it is convenient to achieve self-locking after the turbulence generation boat is lifted in place.

[0043] Among them, the self-driven turbulence generating device includes a rotating shaft 11 arranged on the turbulence generating ship along the width direction of the turbulence generating ship. Both ends of the rotating shaft 11 penetrate out of the turbulence generating ship 5, and a circle of impellers 12 are installed outside the turbulence generating ship respectively. The impellers at the lower part of the rotating shaft are immersed below the water surface, and the rotating shaft 11 is connected to a driving motor 14 installed on the turbulence generating ship through a transmission belt 13.

[0044] In this way, by driving the impellers to rotate through the driving motor, while generating waves and creating turbulence, it also drives the turbulence generating ship to move forward. It has the advantages of simple structure, good wave generation and turbulence creation while being self-driven. Additionally, during implementation, storage batteries can be respectively set on the turbulence generating ship and the connecting frame to provide power for their respective motors, or power can be supplied by connecting to an external power source through wires, which will not be elaborated here. Additionally, during implementation, several openings can be further distributed on the blades of the impeller, and the edges of the openings are serrated. In this way, when the impeller rotates to push the water flow, a better turbulence creation effect can be produced.

[0045] Additionally, during implementation, referring to Figure 2 , a rectangular opening 26 is further provided on the blade 25 of the impeller 12, and multiple elastic bandages 27 are arranged in parallel within the opening. Each elastic bandage 27 shields the opening as a whole and has different elastic forces. In this way, when the impeller rotates to push the water flow, due to the different elastic forces of each elastic strip, different gap distances can be pressed out between the strips by the water pressure for the water flow to pass through, so a more chaotic turbulent flow effect can be created, greatly improving its turbulence creation and anti-freezing effects. During implementation, the elastic bandages can be obtained from rubber skins with different elastic forces.

[0046] Among them, it further includes a control center (not shown). A distance sensor 15 is provided on each side of the lower end of the slider 2. The distance sensor 15 is connected to the control center, and the control center is connected to the driving motor 14.

[0047] In this way, when the distance sensor detects that the turbulence generating ship is approaching the shore, it gives a signal, and the control center controls the driving motor to switch between forward and reverse rotations, realizing the automatic control of the turbulence generating ship to travel back and forth along the set path.

[0048] Among them, a temperature control detection module is further provided in the water channel. The temperature control detection module is connected to the control center, and the control center is connected to the lifting motor.

[0049] In this way, when the temperature control detection module automatically detects that the water flow temperature in the water channel has decreased to the required level, it automatically controls the lifting motor to start through the control center, realizing the automatic detection and opening / closing control of the system equipment.

[0050] In this embodiment, the temperature control detection module includes a detection float 16. The detection float 16 is vertically slidably installed through a detection vertical rod 17 standing in the water channel. A temperature sensor 18 is provided at a position below the water surface on the detection float 16 and is connected to the control center.

[0051] In this way, the temperature sensor is not affected by water flow and water level fluctuations, and can automatically detect the water flow temperature to achieve automatic induction control.

[0052] As another implementable option, the temperature control detection module includes a detection float 19 floating on the water surface of the water channel. The detection float 19 has an upward installation groove, and an elastic airbag 20 is arranged in the installation groove. The upper surface of the elastic airbag 20 has a horizontally arranged piston. A piston rod 21 is fixedly arranged upward at the upper end of the piston. A power brush head 22 is fixedly arranged horizontally at the upper end of the piston rod 21. The outer end of the power brush head 22 can be slid up and down in cooperation with a vertically arranged conductive bar 23. One end of the conductive bar 23 and the power brush head form a variable resistor and are connected to a temperature detection circuit (not shown). The temperature detection circuit is connected to the control center; a phase change gas is arranged in the elastic airbag 20.

[0053] In this way, when the water flow temperature in the water channel is lower than the preset temperature, the phase change gas changes from a gaseous state to a liquid state, the volume shrinks and drives the power brush head to slide down, changing the resistance of the variable resistor, and then relying on the temperature detection circuit to detect the temperature; then relying on the control center to perform corresponding control operations. Therefore, the temperature detection module with this structure can achieve real-time temperature monitoring and feedback, is sensitive and reliable in response, has a simple structure, and is convenient to implement. When specifically implemented, the temperature detection circuit is a prior art, that is, it can convert the resistance change of the variable resistor into an electrical signal, and will not be elaborated here specifically.

[0054] Among them, a first phase change gas and a second phase change gas are mixed and arranged in the elastic airbag 20. The phase change temperature of the first phase change gas is 0 - 5 °C, and the phase change temperature of the second phase change gas is -10 - 0 °C.

[0055] In this way, by controlling and adjusting the ratio of the two phase change gases, the control temperature of the flow turbulence control device can be adjusted within a temperature range, and the temperature value can be adjusted according to needs.
