Description

Technical Field

[0001] This utility model relates to the technical field of teaching demonstration tools, specifically to a teaching hydroelectric power generation demonstration device. Background Technology

[0002] Hydropower demonstrations are not only aesthetically pleasing models, but also important tools for effectively disseminating knowledge about hydropower and showcasing a company's technological strength and innovative achievements in the field. Therefore, they are often used in teaching to help students gain a clearer understanding of each stage of hydropower generation and appreciate the charm of the integration of technology and nature.

[0003] A search revealed an existing patent (publication number: CN222051132U) disclosing a teaching hydroelectric power generation demonstration device, including a main body, an ammeter, a voltmeter, and a light bulb. A fixing groove is formed around the perimeter of one side of the rear end of the upper surface of the main body. An ammeter is fixedly connected to one side of the rear end of the upper surface of the main body, and a voltmeter is fixedly connected to the middle of one side of the rear end of the upper surface of the main body. A light bulb is fixedly connected to one side of the rear end of the upper surface of the main body away from the center of the voltmeter. A water tank is fixedly connected to one side of the rear end of the upper surface of the main body away from the center of the main body. In this invention, a transparent cover is engaged with the fixing groove on the main body, preventing water from splashing onto the ammeter, voltmeter, and light bulb, thus enhancing safety during use. Water is released through a drain pipe; when the water flows through the turbine, the turbine rotates, driving a connected generator to produce electricity. The power generation effect can then be demonstrated through the connected light bulb.

[0004] However, the above scheme can only show the impact of water flow on the amount of electricity generated, without intuitively demonstrating the impact of potential energy generated by height difference on the amount of electricity generated. This is not conducive to better demonstrating the actual factors affecting hydropower generation and reduces the corresponding teaching demonstration effect.

[0005] In view of this, this utility model proposes a demonstration device for hydroelectric power generation in teaching. Utility Model Content

[0006] This invention proposes a demonstration device for hydroelectric power generation in teaching, which solves the problem in related technologies that it is inconvenient to demonstrate the impact of height difference and water flow on the generation of electricity.

[0007] The technical solution of this utility model is as follows: A teaching hydroelectric power generation demonstration device includes a fixed box; an indicator light, an ammeter, and a voltmeter fixedly connected to one side of the front of the fixed box; a cavity is opened inside the fixed box; a water turbine is rotatably connected to the upper end of the inner wall of the cavity; a drain pipe is fixedly connected to the lower end of one side of the fixed box; a generator is fixedly connected to the upper end of the other side of the fixed box; the output end of the water turbine is fixedly connected to the input end of the generator through a coupling; a water storage tank is set above the fixed box; a drain pipe is fixedly connected to one end of the bottom of the water storage tank; a filter assembly is assembled on the top of the water storage tank, which is used to filter the added water to prevent impurities from adhering too much to the surface of the water turbine and affecting its rotation and conversion effect; an adjustment assembly is assembled on the top of the fixed box, which is used to realize the up and down sliding of the water storage tank.

[0008] The adjustment assembly includes: a fixed seat fixedly connected to one side of the top of the fixed box, with a threaded rod rotatably connected to the inner wall of the fixed seat; a threaded block threadedly connected to the surface of the threaded rod, with one side of the threaded block fixedly connected to the lower end of one side of the water tank; and a rotating handle rotatably connected to the top of the fixed seat through friction pad damping, with the bottom end of the rotating handle fixedly connected to the top end of the threaded rod.

[0009] Preferably, a sliding rod is fixedly connected to the other side of the top of the fixed box, and a slider that slides in cooperation with the surface of the sliding rod is fixedly connected to the lower end of the other side of the water storage tank.

[0010] Preferably, a scale is fixedly connected to the front of the fixed base, and an indicator block is fixedly connected to the front of the threaded block.

[0011] Preferably, the filter assembly includes: symmetrical slots formed on the upper part of the inner wall of the water storage tank; a filter frame movably connected to the upper part of the inside of the water storage tank, with symmetrical locking blocks fixedly connected to both sides of the filter frame; and a locking seat fixedly connected to the top of the filter frame, with a handle fixedly connected to the top of the locking seat.

[0012] Preferably, the card block and the card slot form an engaging structure, and the card block and the card slot are convex in shape.

[0013] Preferably, the card holder is in the shape of an inverted U, and the inner wall of the card holder forms an engaging structure with both ends of the water storage tank.

[0014] Preferably, a viewing window is fixedly connected to the front of the fixed box, which allows the user to clearly observe the rotation of the water turbine.

[0015] Preferably, a water collection hopper is fixedly connected at the middle position of the top of the fixed box, and the inner wall of the water collection hopper is inclined.

[0016] Preferably, a guide plate is fixedly connected to the inner bottom wall of the cavity, and the top of the guide plate is inclined at an angle of 20 degrees to the horizontal direction.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, rotating the handle drives the threaded rod to rotate, causing the threaded block to slide and thus causing the water tank to slide up and down. The sliding of the threaded block also causes the indicator block to slide. With the help of a scale, the vertical sliding height of the water tank can be clearly known, thereby changing the distance between the bottom of the water pipe and the turbine. The scale can be used to achieve equal height adjustment, which allows for demonstration of the impact of water flow at different heights on power generation. At the same time, the valve on the water pipe can be used to change the water flow rate discharged from the water pipe, thereby demonstrating the impact of different water flow rates on power generation. This realizes the demonstration of height and water flow, improving its teaching demonstration effect.

[0019] 2. In this utility model, a filter frame is used to filter the water added into the water storage tank, thereby filtering out impurities in the water. This prevents excessive adhesion of impurities to the surface of the water turbine, which would affect the power generation of the generator. It also prevents impurities from affecting the smooth operation of the water turbine, extending its service life. Furthermore, the filter frame can be quickly installed and removed from the top of the water storage tank by using the locking block and the locking slot, as well as the locking seat and the top of the water storage tank. This makes it easy to remove the filter frame and centrally process the filtered impurities, improving its practicality. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0028] Example 1

[0029] A preferred embodiment of the teaching hydroelectric power generation demonstration device provided by this utility model is, for example... Figures 1 to 5 The diagram shows a demonstration device for hydroelectric power generation in teaching, comprising a fixed box 6; an indicator light 7, an ammeter 8, and a voltmeter 10 fixedly connected to one side of the front of the fixed box 6; a cavity 13 inside the fixed box 6, with a water turbine 14 rotatably connected to the upper end of the inner wall of the cavity 13; a drain pipe 11 fixedly connected to the lower end of one side of the fixed box 6; a generator 9 fixedly connected to the upper end of the other side of the fixed box 6; the output end of the water turbine 14 fixedly connected to the input end of the generator 9 via a coupling; a water storage tank 3 located above the fixed box 6, with a drain pipe 15 fixedly connected to one end of the bottom of the water storage tank 3; a filter assembly 2 mounted on the top of the water storage tank 3, used to filter the added water to prevent impurities from adhering excessively to the surface of the water turbine 14 and affecting its rotation and conversion efficiency; and an adjustment assembly 1 mounted on the top of the fixed box 6, used to allow the water storage tank 3 to slide up and down.

[0030] The adjustment assembly 1 includes: a fixed seat 101 fixedly connected to one side of the top of the fixed box 6, with a threaded rod 105 rotatably connected to the inner wall of the fixed seat 101; a threaded block 106 threadedly connected to the surface of the threaded rod 105, with one side of the threaded block 106 fixedly connected to the lower end of one side of the water tank 3; and a handle 108 rotatably connected to the top of the fixed seat 101 by friction pad damping, with the bottom end of the handle 108 fixedly connected to the top end of the threaded rod 105.

[0031] In this embodiment, rotating the handle 108 drives the threaded rod 105 to rotate, causing the threaded block 106 to slide and drive the water tank 3 to slide up and down. The sliding of the threaded block 106 will also drive the indicator block 107 to slide. With the help of the scale 102, the height of the water tank 3 sliding up and down can be clearly known. In this way, the distance between the bottom end of the water pipe 15 and the water turbine 14 can be changed, so that the impact of water flow impact at different heights on power generation can be demonstrated.

[0032] In a further preferred embodiment of the present invention, a sliding rod 103 is fixedly connected to the other side of the top of the fixed box 6, and a slider 104 that slides and engages with the surface of the sliding rod 103 is fixedly connected to the lower end of the other side of the water storage tank 3.

[0033] In this embodiment, the smoothness of the water tank 3 sliding up and down is further improved by utilizing the sliding of the slider 104 and the surface of the slider 103.

[0034] In a further preferred embodiment of the present invention, a scale 102 is fixedly connected to the front of the fixed base 101, and an indicator block 107 is fixedly connected to the front of the threaded block 106.

[0035] In this embodiment, the cooperation between the indicator block 107 and the scale 102 makes it easy for the user to clearly know the vertical sliding distance of the water tank 3.

[0036] Example 2

[0037] Based on Embodiment 1, a preferred embodiment of the teaching hydroelectric power generation demonstration device provided by this utility model is as follows: Figures 1 to 5 As shown: The filter assembly 2 includes: a slot 205 symmetrically opened on the upper part of the inner wall of the water storage tank 3; a filter frame 201 movably connected to the upper part of the inside of the water storage tank 3, with a locking block 202 symmetrically fixedly connected to both sides of the filter frame 201; and a locking seat 203 fixedly connected to the top of the filter frame 201, with a handle 204 fixedly connected to the top of the locking seat 203.

[0038] In this embodiment, the filter frame 201 is used to filter the water added to the water storage tank 3 to remove impurities from the water. This prevents excessive adhesion of impurities on the surface of the water turbine 14, which would affect the power generation of the generator 9. After the demonstration is completed, the filter frame 201 can be removed from the top of the water storage tank 3 to facilitate thorough cleaning and prevent clogging of the filter frame 201.

[0039] In a further preferred embodiment of the present invention, the card block 202 and the card slot 205 form an engaging structure, and the shapes of the card block 202 and the card slot 205 are convex.

[0040] In this embodiment, the engagement between the convex locking block 202 and the slot 205 is used to improve the firmness of the engagement between the filter frame 201 and the upper part of the water storage tank 3.

[0041] In a further preferred embodiment of this utility model, the card holder 203 is inverted U-shaped, and the inner wall of the card holder 203 forms an engaging structure with both ends of the water storage tank 3.

[0042] In this embodiment, the inverted U-shaped bracket 203 engages with the top of the water tank 3 to facilitate the support and positioning of the filter frame 201 after it is engaged and installed.

[0043] In a further preferred embodiment of this utility model, a viewing window 5 is fixedly connected to the front of the fixed box 6, and the viewing window 5 allows the user to clearly observe the rotation of the water turbine 14.

[0044] In a further preferred embodiment of this utility model, a water collecting hopper 4 is fixedly connected at the middle position of the top of the fixed box 6, and the inner wall of the water collecting hopper 4 is inclined.

[0045] In this embodiment, the use of the inclined water collection hopper 4 can prevent water from splashing out from the top opening of the cavity 13.

[0046] In a further preferred embodiment of the present invention, a guide plate 12 is fixedly connected to the inner bottom wall of the cavity 13, and the top of the guide plate 12 is inclined at an angle of twenty degrees to the horizontal direction.

[0047] In this embodiment, the inclined guide plate 12 is used to facilitate the guidance of water inside the cavity 13, so that it can be discharged from the drain pipe 11 more quickly and thoroughly.

[0048] The working principle of this utility model is as follows: First, water is added into the water storage tank 3. At this time, the water added into the water storage tank 3 is filtered by the filter frame 201 to filter out impurities in the water. This can prevent too many impurities from adhering to the surface of the water turbine 14, which would affect the power generation of the generator 9 and extend its service life. Then, the drain pipe 15 can be opened to drain water and change the drain flow rate, so that the water falls from the drain pipe 15 to the water turbine 14, thereby causing the water turbine 14 to rotate and generate electricity through the generator 9. This will cause the indicator light 7 to light up. The voltage and current of the power generation can be known by the ammeter 8 and the voltmeter 10. At the same time, the flow rate of the water discharged from the drain pipe 15 is changed by the valve. The relationship between the water flow rate and the power generation can be known by the indicator light 7, the ammeter 8 and the voltmeter 10.

[0049] The valve on the drain pipe 15 is kept open at a fixed angle. Then, the screw rod 105 is rotated by rotating the handle 108. The screw rod 105 and the screw block 106 are threaded together, causing the screw block 106 to slide and drive the water tank 3 to slide up and down. The sliding of the screw block 106 will also drive the indicator block 107 to slide. With the help of the scale 102, the height of the water tank 3 can be clearly known. In this way, the distance between the bottom of the drain pipe 15 and the turbine 14 can be changed, so that the impact of water flow impact at different heights on power generation can be demonstrated.

[0050] Simultaneously, the used water will flow into the cavity 13, and the valve on the drain pipe 11 will be opened. The guide plate 12 will then guide the water to be discharged in a concentrated manner, which will facilitate the recycling and reuse of the used water. After the demonstration, the filter frame 201 can be removed from the top of the water storage tank 3 by pulling the handle 204, which will facilitate the thorough cleaning and anti-clogging of the filter frame 201. During installation, the locking block 202 is locked into the slot 205, and the locking seat 203 is locked into the top of the water storage tank 3, so that the filter frame 201 is locked into the upper part of the water storage tank 3.

[0051] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
