Description

Technical Field

[0001] The utility model relates to an experimental water tank, in particular to an experimental water tank which can simulate tidal processes and generate electricity. Background Art

[0002] The well-known tidal power generation experimental device is composed of a reservoir, a water tank, a water supply pump, and a hydro-turbine generator. The water supply pump is connected to the water tank with a water supply pipe, and a bidirectional water pump is controlled to pump water from one side of the water tank into the reservoir to make the water level rise to simulate high tide. The bidirectional water pump pumps water out of the reservoir on one side to simulate the low tide process, and the hydro-turbine generator set is used to complete power generation.

[0003] The disadvantages of the existing device are: 1. It uses a water tank and a water pump structure, which occupies a large area and is not portable. 2. It uses pumping and water storage to simulate the rise and fall of tides, which is complicated to operate and expensive. Utility Model Content

[0004] The utility model aims to provide an experimental water tank, which simulates the tide level fluctuation only by controlling the expansion and contraction of air bags on both sides, avoids the use of water tanks and water pumps, simplifies operation, reduces floor space, reduces construction costs and is portable.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the experimental water tank includes a partition, a left water reservoir, a right water reservoir, a central dam body, a valve, a hydro-generator, a power meter, a water level gauge, a detachable air pump, a left air guide channel, a left air bag, a left air pipe, a right air guide channel, a right air bag, and a right air pipe. The central dam body separates the water reservoir, and the partition separates the left and right water reservoirs into upper and lower chambers respectively. In the upper chamber, the valve, the hydro-generator, the power meter, and the water level gauge in the dam body are electrically connected; in the lower chamber, the left air bag, the left air pipe, and the left air guide channel are sequentially connected to the left air pump port on the upper surface of the dam body, and the right air bag, the right air pipe, and the right air guide channel are sequentially connected to the right air pump port; the detachable air pump is located on the upper cover of the experimental box, and after the air pump is connected to the left air pump port or the right air pump port on the upper surface of the dam body, it will be sequentially connected to the corresponding side air guide channel, air pipe, and air bag.

[0006] The left or right air bag is located in the lower chamber on the corresponding side, and is used in conjunction with the air pipe, air guide channel, and detachable air pump on that side. Taking the left side as an example, when simulating the high tide process, the air pump is installed to the air pump port on the left side, and the air bag on the left side is inflated to increase the volume of the air bag on the left side, thereby squeezing the water in the lower chamber on the left side into the upper chamber through the leakage hole of the partition, so that the water level of the left water reservoir rises and is higher than the water level of the right water reservoir, resulting in a water level difference; when simulating the low tide process, the left air pump is controlled to deflate, so that the volume of the left air bag shrinks, and the water in the upper chamber naturally falls to the lower chamber through the leakage hole, and the water level drops and is lower than the water level of the right water reservoir, resulting in a water level difference.

[0007] The gate is located in the upper chamber and is used in conjunction with a generator and a water level gauge. After the water level difference is measured by the water level gauge, the power generation process is completed by controlling the opening and closing of the valve.

[0008] The beneficial effects of the present invention are as follows: the problems that a water storage tank and a two-way water pump type experimental water tank simulating tidal fluctuation occupy a large area, are complicated to operate and cannot be carried, and the cost of the device can be reduced.

Implementation

[0014] like Figures 1 to 3As shown, the experimental water tank comprises a left water reservoir (22), a right water reservoir (23), a baffle (5), a central dam body (2), a turbine generator (3), a valve (4), a power meter (8), a water level gauge (9), a detachable two-way air pump (11), a left air guide channel (21), a left air pipe (6), a left air bag (7), a right air guide channel (18), a right air pipe (20), and a right air bag (19). The baffle (5) separates the two water reservoirs into two chambers. In the upper chamber (15), the left water reservoir (22) and the right water reservoir (23) are separated by the central dam body (2). The valve (4), the turbine generator (8), and the water level gauge (9) are in the dam body (2). The motor (3), the power meter (9), and the water level meter (10) are electrically connected; the left air bag (7), the left air pipe (6), and the left air guide channel (21) in the lower chamber (16) are sequentially connected to the left air pump port (14) on the surface of the central dam body (2); the right air bag (19), the right air pipe (20), and the right air guide channel (18) are sequentially connected to the right air pump port (10); the detachable two-way air pump (11) is located on the upper cover of the experimental box. Taking the left side as an example, the detachable two-way air pump (11) is connected to the left air pump port (14) on the upper surface of the central dam body (2) and then connected to the left air guide channel (21), the left air pipe (6), and the left air bag (7) in sequence.

[0015] like Figure 2~3 As shown, when simulating the high tide process, taking the left side as an example, the detachable two-way air pump (11) is connected to the left air pump port (14), and the inflation button (12) is pressed to start inflation so that the left air bag (7) expands, and the water in the lower chamber (16) rises to the upper chamber (15) through the leaking hole (17), so that the water level on the left side rises. Since the volume of the right air bag (19) remains unchanged, the water level of the right water reservoir (23) remains unchanged, and a water level difference appears on the left and right sides; when simulating the low tide process, the deflation button (13) is pressed to control the air pump (11) to deflate, and the volume of the left air bag (7) decreases, so that the water in the upper chamber (15) drops to the lower chamber (16) through the leaking hole (17), so that the water level in the left water reservoir (22) drops. Since the volume of the right air bag (19) remains unchanged, the water level of the right water reservoir (23) remains unchanged, and a water level difference appears on the left and right sides.

[0016] like Figure 1 As shown, according to the display of the water level meter (10), when the water level difference increases, the valve switch (1) is pressed to control the valve (4) to open, so that the turbine generator (3) works, and the potential energy of the water level difference is converted into electrical energy. The amount of electricity generated is measured and displayed by the power meter (9).
