Description

Technical Field

[0001] The utility model relates to the technical field of navigation tools, in particular to an air intake component for a fresh water generating device. Background Art

[0002] Ships need to carry fresh water when going out to sea. When there is insufficient fresh water, or some ships reduce the amount of fresh water they carry in order to carry more cargo, they need to use seawater desalination equipment on board. However, most existing seawater desalination equipment heats water to boil and then condenses it to produce fresh water. The equipment is heavy, large in size, and has high energy consumption.

[0003] The air above the sea surface generally has a high humidity and is fully fluid under the action of the sea breeze. Therefore, if fresh water can be obtained using the high-humidity air above the sea surface as a raw material, it is expected to reduce energy consumption and simplify the preparation process. Due to the low density of air and limited water content, a continuous and large air flow is required to ensure a certain production efficiency. The fan is an accessory that can drive the airflow to flow continuously through the device, but in the sea surface environment, it is also difficult to provide a continuous power supply for the fan. Even if the fan is powered by solar panels, it is also faced with problems such as difficulty in power supply on cloudy days and at night. Summary of the invention

[0004] The utility model aims to provide an air intake assembly for a fresh water generating device in view of the technical defects of the prior art, so as to solve the technical problems of the current device for producing fresh water using seawater as raw material, such as heavy weight, large volume and high energy consumption.

[0005] Another technical problem to be solved by the utility model is how to produce fresh water using the high-humidity air above the sea surface as a raw material.

[0006] Another technical problem to be solved by the utility model is how to ensure the air intake efficiency of the device in the absence of power supply.

[0007] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0008] An air intake assembly for a fresh water generating device comprises an outer tube body, an inner tube body, a distribution bin, a condenser, a water storage tank, a support plate, a shell, a tail and an air inlet, wherein a portion of the inner tube body is coaxially nested in the outer tube body, an annular channel between the inner tube body and the outer tube body is connected to the distribution bin, two ends of the condenser are respectively connected to the distribution bin and the water storage tank, the lower end of the inner tube body passes through the distribution bin and is connected to the water storage tank, a support plate is fixedly connected to the outside of the outer tube body, a shell is rotatably connected to the upper end of the outer tube body, a tail and an air inlet are respectively provided on the left and right sides of the shell, and the upper end of the inner tube body is maintained outside the outer tube body.

[0009] Preferably, an inner tube stopper is provided between the outer tube body and the inner tube body.

[0010] Preferably, the inner tube limiter is tubular, the outer wall of the inner tube limiter is in contact with the inner wall of the outer tube body, the inner wall of the inner tube limiter is in contact with the outer wall of the inner tube body, and a through hole is provided on the tube wall of the inner tube limiter which penetrates along its axial direction.

[0011] Preferably, the condenser tube comprises a plurality of fins, the plurality of fins intersect at the axis position of the condenser tube, and an arc panel is provided between the outer edges of every two adjacent fins.

[0012] Preferably, the angles between every two adjacent fins are equal.

[0013] Preferably, the number of fins is 5.

[0014] Preferably, the arc panels are of the same shape, and the cross section of the arc panels is an arc, and the radius of the arc is smaller than the width of the fin.

[0015] Preferably, a counterweight is fixedly connected to the bottom end of the water storage tank.

[0016] Preferably, the rotational connection of the shell at the upper port of the outer tube body is achieved by the following structure: a lower stabilizing rod is fixedly connected transversely to the inner wall of the outer tube body, a rotating needle is fixedly connected vertically to the lower stabilizing rod, an upper stabilizing rod is fixedly connected transversely to the inner wall of the shell, a bearing is installed on the top wall of the shell, and a hole is provided on the upper stabilizing rod, the rotating needle passes through the hole and is rotationally connected to the bearing (the rotating needle is inserted straight to the bottom to reach the bearing and rests against the bearing, and the steel needle head can be changed into a screw and inserted to fix it at the place where it rests against the bearing).

[0017] When actually selecting an arrow, the tail needs to have a relatively large area to ensure that the power generated by the wind at the tail is greater than the resistance at the air inlet. In other words, the tail size of the actual product is larger and is not limited to the tail size directly presented in the drawings of the specification. This is hereby explained.

[0018] In the above technical scheme, the water-containing air reaches the deep low-temperature condenser (i.e., the lower structure of the utility model) after passing through the coaxial sleeve interlayer (i.e., the channel between the outer tube body and the inner tube body), and is distributed into the plum blossom-shaped condenser tube after passing through the air intake distributor (distribution bin); the moisture in the air is condensed by the condenser tube and accumulated in the bottom water storage tank; the dry air leaves the water storage tank upward through the inner tube body and is then discharged.

[0019] In order to realize efficient natural wind air intake, the utility model rotates the connection shell at the upper port of the outer tube body, and uses the tail of the arrow to face the wind, thereby ensuring the air intake efficiency.

[0020] The structural features of the utility model are as follows:

[0021] 1. The design of the windward air intake tail steering device. When it is night or cloudy without sunshine, the auxiliary evaporation equipment and the air intake fan cannot work, so it is necessary to let the natural wind enter the air intake. The utility model innovatively designs a transfer unit that always takes in air against the wind. It covers the air intake pipe and is connected to a small bearing in the middle with a central axis, which plays a role of smooth deflection and always takes in air against the wind.

[0022] 2. The air intake is automatically filled with sea breeze, and the entire equipment has zero energy consumption. It does not require additional electricity or diesel to heat and evaporate seawater.

[0023] 3. The design of coaxial air inlet and outlet pipes sets the wet air inlet pipe and the dry air outlet pipe in the same pipe. The wet air enters through the gap between the inner and outer pipes, and the dry air goes out of the inner pipe. This design allows the low-temperature dry air to exchange heat with the higher-temperature intake air in the pipe to pre-cool the intake air. At the same time, it also prevents the outlet pipe from condensing due to the low temperature and blocking the upward outlet pipe.

[0024] 4. The design of the inner tube limiter ensures a fixed gap between the inner tube and the outer tube, ensuring smooth air intake.

[0025] 5. The plum blossom-shaped cross-section of the heat exchange tube increases the contact area between the heat exchange tube and seawater, and improves the cooling efficiency of the deep seawater on the heat exchange tube. The heat-conducting fins inside the heat exchange tube improve the cooling efficiency of the air inside the tube, which promotes the miniaturization of the equipment.

[0026] The utility model discloses an air intake assembly for a fresh water generating device. This technical solution utilizes the temperature difference between the sea surface and different water depths to condense the moisture in the air on the sea surface using the low temperature deep in the sea water. The device is light and compact, only the size of a thermos, does not require energy consumption, and the material is resistant to seawater corrosion and has a long service life. It is particularly suitable for small ships as an emergency fresh water source. Because of its small size, light weight and durability, it can also be used as fresh water generating equipment for special operations personnel when performing missions on islands. Moreover, the utility model adds a windward mechanism at the air intake end to ensure the natural air intake efficiency, so that the device can still maintain a high fresh water preparation capacity when power is unavailable.
