Description

Technical Field

[0001] This utility model relates to the field of nearshore engineering technology, and more specifically to a bidirectional movable water tank ventilation device. Background Technology

[0002] In near-shore engineering fields such as shipbuilding and ports, wind is an important environmental factor. More and more engineering tests need to take wind speed into account, so wind-generating systems are often used in ship models and hydraulic engineering tests. At present, most water tank wind-generating systems are fixed. When the test water level is low, the wind-passing area above the water surface is large, resulting in low wind-generating efficiency. When the test location is far from the wind-generating system, the wind speed is affected by friction loss, resulting in low wind-generating efficiency.

[0003] Therefore, there is an urgent need to develop a ventilation device that meets the needs of near-shore engineering projects such as ships and ports. This system should be able to adapt to the ventilation requirements of different water depths and locations in water tank tests and have a high-efficiency ventilation capability. Utility Model Content

[0004] To address the shortcomings of the aforementioned technical solutions, the purpose of this utility model is to provide a bidirectional movable water tank ventilation device.

[0005] The objective of this utility model is achieved through the following technical solution.

[0006] A bidirectional movable water tank ventilation device includes a traveling trolley, a telescopic component, a fan assembly, and a counterweight assembly. The traveling trolley is slidably mounted on the wall of the water tank to move along the length of the water tank. The telescopic component is bolted to one side of the traveling trolley, and the counterweight assembly is mounted on the other side of the traveling trolley to maintain the balance of the device. The fan assembly is mounted at the bottom of the telescopic component to move along the height of the water tank.

[0007] In the above technical solution, multiple telescopic components are provided according to the width of the water tank, and the telescopic components are linked together to move the fan assembly along the height direction of the water tank.

[0008] In the above technical solution, a track is laid on the top of each wall of the water tank, and the traveling trolley is slidably installed on the track, which is a hot-rolled steel rail.

[0009] In the above technical solution, the traveling trolley includes a first truss and two-sided driving wheels and one-sided driven wheels installed at the bottom of the first truss. The first truss is slidably installed on the track through the two-sided driving wheels and the one-sided driven wheels. The two-sided driving wheels are arranged opposite each other on opposite sides of the bottom of the first truss through shafts. The two-sided driven wheels are arranged opposite each other on opposite sides of the bottom of the first truss through shafts. The two-sided driving wheels are connected to a servo motor, which drives the traveling trolley to move.

[0010] In the above technical solution, a fan frame is installed at the bottom of the telescopic component, and a fan assembly is installed at the bottom of the fan frame.

[0011] In the above technical solution, the fan frame is a second truss made of stainless steel, and its width is equal to the width of the water tank. The top is connected to the expansion joint by bolts, and the fan assembly is installed upside down on the bottom of the fan frame by bolts.

[0012] In the above technical solution, the wind turbine assembly includes a wind generator and rubber shock absorbers. Each wind generator is installed at the bottom of the wind turbine frame via four mounting bases, and a rubber shock absorber is installed on each mounting base.

[0013] In the above technical solution, the counterweight assembly includes a counterweight box and a counterweight block. Each counterweight box is installed on the first truss, and the counterweight block is installed inside the counterweight box. The mass of the counterweight block is equal to the total mass of the telescopic component, the fan frame, and the fan assembly, so as to prevent the traveling trolley from tipping over during movement.

[0014] In the above technical solution, the telescopic component is a multi-stage telescopic cylinder.

[0015] The advantages and beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a multi-stage telescopic cylinder to move the fan along the height of the water tank, and can flexibly adjust along the height to ensure the air generation needs of different test water depths; in addition, the fan can be moved along the length of the water tank by a traveling trolley to ensure the air generation needs of different test positions.

[0017] 2. By using a mobile wind generator, this utility model can ensure that the power of the wind generator is reduced while maintaining the same wind generation performance, thus reducing the purchase cost of the wind generator. Secondly, the mobile wind generator adopts an automated approach, which reduces the workload of manually raising the wind generator and building temporary wind tunnels, saving labor costs and shortening the test cycle.

[0025] The traveling trolley 2 includes a first truss 2.1 and two double-sided drive wheels 2.2 and two edgeless driven wheels 2.3 installed at the bottom of the first truss 2.1. The first truss 2.1 is slidably mounted on the track 1 through the double-sided drive wheels 2.2 and the edgeless driven wheels 2.3 to ensure that the traveling trolley does not derail during movement and to avoid jamming during movement. The two double-sided drive wheels 2.2 are connected by axles and are arranged on opposite sides of the bottom of the first truss 2.1. The two edgeless driven wheels 2.3 are connected by axles and are arranged on opposite sides of the bottom of the first truss 2.1. The double-sided drive wheels 2.2 are connected to a servo motor, which drives the traveling trolley 2 to move.

[0026] The fan frame 4 is a second truss made of stainless steel, and its width is equal to the width of the water tank 7. The top is connected to the expansion joint 3 by bolts. The fan assembly 5 is bolted upside down to the bottom of the fan frame 4. The fan assembly 5 includes four air generators 5.1 and rubber shock absorbers. Each air generator 5.1 is mounted on the connecting plate at the bottom of the fan frame 4 through four mounting seats 5.2. Each mounting seat 5.2 is equipped with a rubber shock absorber to reduce the vibration caused by the air generator during operation.

[0027] The counterweight assembly 6 includes multiple counterweight boxes and counterweight blocks. Each counterweight box is installed on the first truss 2.1 of the traveling trolley 2.

[0028] Example 2

[0029] A method for simulating wind and waves in a nearshore engineering flume test, the method being implemented by the bidirectional movable flume wind generator and wave generator described in Example 1, wherein the flume wind generator and wave generator are placed at opposite ends of the flume along its length.

[0030] The methods for simulating wind and waves include the following steps:

[0031] Step 1: Fill the water tank with water until the required amount for the test is reached;

[0032] Step 2: Turn on the wave generator and fan assembly to simulate wind speed, air volume and waves in the tidal current, and collect various data such as wave height, flow velocity and water level in the water tank. At the same time, according to the needs of the experiment, move the traveling trolley to move the fan assembly along the length of the water tank, and drive the telescopic component to move the fan assembly along the height of the water tank, so as to simulate wind speed and air volume at different positions in the water tank.

[0033] In this embodiment, the water tank 7 has a length of 98m, a width of 4m, a height of 2m, a test water depth of 0.4m-1.2m, a maximum wave height of 0.5m, and a maximum wind speed of 25m / s.

[0034] Compared to traditional technologies, the wind speed at a distance of 20m from the fan outlet is approximately 22.7m / s, at 30m it is approximately 18.3m / s, and at 50m it is approximately 15.4m / s. The wind speed decreases with increasing distance from the fan outlet. In this embodiment, the device has an effective moving distance of 70m along the length of the water tank and a moving distance of 0.6m in the height direction. The air-generating range with a wind speed of 25m / s covers the entire steel structure section of the test water tank. Therefore, the device and method of this embodiment have significant advantages in efficient air generation.

[0035] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0036] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0037] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
