Description

Technical Field

[0001] The present invention relates to the technical field of energy generation, and in particular to a precise control system for increasing and decreasing pressure of electromagnetic high-pressure water hammer and high-pressure jet in a hydropower station. Background Art

[0002] Hydropower generation is the study of engineering construction that converts water energy into electrical energy. The water energy used in hydropower generation is mainly the potential energy contained in the water body, which is used to convert water energy into electrical energy. Therefore, in some places where the water body has a drop in height, hydropower generation equipment will be added to generate hydropower.

[0003] Most of the existing hydroelectric power generation equipment relies on natural water bodies. The hydroelectric power generation equipment is built in a water section with a drop in the natural water body. Such hydroelectric power generation equipment cannot circulate the water potential energy for power generation. Therefore, some hydroelectric power generation equipment will use a water hammer pump mechanism to use the water hammer effect to pump the water to a high place to accumulate potential energy, so as to achieve sustainable circulation of water power generation. However, the existing water hammer structure also relies on the natural flow potential energy of the water body to pump the water. Such pumping water pressure cannot be controlled, so that the water pumping cannot be controlled, and thus this type of power generation equipment cannot obtain better water storage control. Therefore, this plan proposes a precise control system for electromagnetic high-pressure water hammer and high-pressure jet pressure increase and decrease in pressure in hydropower stations to solve the above problems.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides Figure 1-9 The electromagnetic high-pressure water hammer and high-pressure jet pressure increase and decrease precision control system of the hydropower station shown includes a main pipeline 1, a one-way drain valve 2 is arranged at one end of the main pipeline 1, an impact valve 3 is arranged in the middle of the main pipeline 1, and a water inlet pipeline 4 is arranged at the other end of the main pipeline 1.

[0032] It should be noted that in this solution, the main pipeline 1, the one-way drainage valve 2, the impact valve 3 and the water inlet pipeline 4 together form a water hammer pump structure, and the pump body can pump water to a high place through the water hammer effect;

[0033] The water hammer effect refers to the phenomenon that when a fluid passes through a pipeline, the pressure in the pipeline fluctuates violently and instantly due to a sudden change in flow rate (such as rapid closing of a valve or starting and stopping of a pump). This phenomenon will generate a shock wave, causing the pressure in the pipeline to increase instantly. By utilizing the change in water pressure and cooperating with the one-way drain valve 2 and the shock valve 3, the water can be pumped to a high place.

[0034] Specifically, the bottom of the main pipeline 1 is fixedly connected with a support seat 101, both sides of the support seat 101 are provided with fixing holes, and the top of the one-way drain valve 2 is provided with a drain pipe 201;

[0035] A pressure gauge 5 is provided in the middle of the pipe wall of the water inlet pipe 4 , and the pressure gauge 5 is used to monitor the pipe pressure of the water inlet pipe 4 .

[0036] It should be noted that, through the provision of the support seat 101, the water hammer pump structure consisting of the main pipeline 1, the one-way drain valve 2, the impact valve 3 and the water inlet pipeline 4 can be fixedly installed. At the same time, through the provision of the pressure gauge 5, the water inlet pressure can be monitored, thereby assisting in the control of the water pressure, thereby ensuring that the water flow pipeline is used within a safe and controllable range.

[0037] The outer wall of the water inlet pipe 4 is provided with an electromagnetic pressure increasing and decreasing mechanism;

[0038] The electromagnetic pressure increasing and decreasing mechanism includes a first encapsulating shell 6 and a second encapsulating shell 7. The bottoms of the first encapsulating shell 6 and the second encapsulating shell 7 are hinged, and a fixing member for locking the first encapsulating shell 6 and the second encapsulating shell 7 is arranged between the tops. An electromagnetic member is arranged in the middle of the first encapsulating shell 6 and the second encapsulating shell 7, and a control member is arranged on the side of the first encapsulating shell 6 away from the second encapsulating shell 7, and the control member is used to control the power output of the electromagnetic member.

[0039] Specifically, the inner walls of the first wrapping shell 6 and the second wrapping shell 7 on opposite sides are spirally wound and symmetrically provided with receiving grooves 702, and the receiving grooves 702 are used for arranging the electromagnetic components;

[0040] The electromagnetic component includes an electromagnetic induction coil 10, which is wound and sleeved on the outer wall of the water inlet pipe 4, and the first wrapping shell 6 and the second wrapping shell 7 are sleeved on the outer wall of the electromagnetic induction coil 10 through the containing groove 702. A control groove is opened on the side of the first wrapping shell 6 away from the second wrapping shell 7, and the control groove is used for the interlaced setting of the control component;

[0041] It should be noted that the opposite sides of the first wrapping shell 6 and the second wrapping shell 7 are both hollow structures, and the containing groove 702 symmetrically formed by the opposite sides of the first wrapping shell 6 and the second wrapping shell 7 is a spiral structure, which is the same as the winding path of the electromagnetic induction coil 10. After the electromagnetic induction coil 10 is wound and sleeved on the outer wall of the water inlet pipe 4, the first wrapping shell 6 and the second wrapping shell 7 are hingedly wrapped so that the containing groove 702 can clamp the electromagnetic induction coil 10. At the same time, when the first wrapping shell 6 and the second wrapping shell 7 are closed, the ends of the two will be tightly sleeved on the outer wall of the water inlet pipe 4, so that the first wrapping shell 6 and the second wrapping shell 7 can complete the sleeve at the water inlet pipe 4, and then the electromagnetic induction coil 10 can be sleeved at the water inlet pipe 4 to control the water pressure by electromagnetic energy.

[0042] By using an electromagnetic field to generate a driving force on the water flow, the effect of accelerating the water flow can be achieved. This method requires a powerful power supply and a conductor (i.e., the electromagnetic induction coil 10 in this solution). When power is turned on, a magnetic field will be generated around the conductor. The magnetic field will exert a force on the charged particles in the water flow, thereby promoting the water flow to accelerate.

[0043] The control component includes a control board 11, which is arranged in the control slot. The two ends of the electromagnetic induction coil 10 are electrically connected to the control circuit input and output ends of the control board 11 respectively. A controller 8 is arranged on the side of the control board 11 away from the second enclosing shell 7.

[0044] It should be noted that the controller 8 is electrically connected to the control end and the power supply end of the control board 11, and a power terminal is provided at the end of the controller 8, which can be connected to an external power supply to transmit power to the control board 11. At this time, the electromagnetic induction coil 10 electrically connected to the control board 11 can be turned on and energized, thereby generating electromagnetic energy.

[0045] Specifically, the fixings include:

[0046] A connecting block 601, which is fixedly connected to the top of the first wrapping shell 6. A connecting groove is provided at the top of the connecting block 601, and a pressing structure is provided between the bottom of the connecting groove and the top of the first wrapping shell 6;

[0047] The hinge seat 701 is fixedly connected to the top of the second wrapping shell 7, and the hinge seat 701 and the connecting block 601 are symmetrically arranged along the horizontal longitudinal center. A fixing rod 9 is hinged in the middle of the hinge seat 701, and the end of the fixing rod 9 away from the hinge seat 701 is interlaced and connected with the connecting groove.

[0048] Furthermore, an end of the fixing rod 9 away from the hinge seat 701 is provided with an external thread, and an extrusion nut is threadedly sleeved on the external thread of the fixing rod 9, and the extrusion nut is used to position the fixing rod 9 by extruding the connecting block 601.

[0049] It should be noted that the fixing rod 9 is hinged at the top of the second encapsulating shell 7 through the hinge seat 701, so that when the tops of the first encapsulating shell 6 and the second encapsulating shell 7 are closed and locked, the first encapsulating shell 6 and the second encapsulating shell 7 are closed first, and then the fixing rod 9 is rotated so that the fixing rod 9 drives one end of the thread to be clamped in the connecting groove of the connecting block 601, and then the nut is rotated so that the nut is close to the connecting block 601, and the nut is used to squeeze the side wall of the connecting block 601, so that the fixing rod 9 is constrained in the connecting groove by extrusion and friction, thereby locking the first encapsulating shell 6 and the second encapsulating shell 7.

[0050] Specifically, a sliding groove is opened in the vertical direction between the inner wall of the bottom end of the connecting groove and the top of the first wrapping shell 6, and the pressing structure includes a pressing rod 603, which is slidably inserted into the sliding groove, and an extrusion block 604 is arranged at the bottom of the pressing rod 603.

[0051] Furthermore, the inner walls on both sides of the sliding groove are provided with supporting grooves 602, and both sides of the pressing rod 603 are fixedly connected with supporting sliders 605. Multiple supporting sliders 605 are respectively slidably inserted and connected in multiple supporting grooves 602, and supporting springs 606 are provided on the inner walls of the supporting grooves 602 and at the bottom ends of the supporting sliders 605.

[0052] It should be noted that, in the initial state, the supporting spring 606 pushes the supporting slider 605 upward. At this time, driven by the supporting slider 605, the pressing rod 603 remains in the inserted state. At this time, the top of the pressing rod 603 will be inserted into the connecting groove. When the fixing rod 9 is pressed down and inserted into the connecting groove, the fixing rod 9 will squeeze the pressing rod 603 downward. At this time, the pressing rod 603 moves downward and drives the squeezing block 604 to be pressed down to the outer wall of the water inlet pipe 4. In the setting of this scheme, the squeezing block 604 is a sponge block, which is deformed after being squeezed and is tightly squeezed on the outer wall of the water inlet pipe 4, thereby squeezing the water inlet pipe 4, thereby ensuring the positioning of the first wrapping shell 6 and the second wrapping shell 7 after being wrapped on the outer wall of the water inlet pipe 4, and ensuring that the electromagnetic pressure increasing and reducing mechanism can be stably set up and used.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
