Abstract

The present invention relates to an automatic salvaging device for floating film on the surface of water in shrimp sheds. Floating film generally refers to the organic layer floating on the water surface during aquaculture, which will hinder the oxygen exchange between water and air, consume oxygen, produce harmful substances, and increase the risk of aquaculture. Due to the uncertainty and persistence of the appearance of floating film, as well as the hysteresis of its harmful effects, the industry generally ignores the treatment of floating film, and there is currently no cheap, environmentally friendly, and labor-saving floating film removal device in the industry. The present invention adopts physical salvage methods, air lift principles, and automatic steering technology to continuously and automatically salvage and separate floating film on the water surface. In conjunction with the use of barriers, the efficiency of floating film salvage can also be greatly improved, enhancing the practicability of the device. The device provides a new method for salvaging and separating floating film in aquaculture.

Description

Technical Field

[0001] The invention relates to an automatic floating film salvaging device, in particular to a device suitable for automatically salvaging floating films on the water surface of shrimp sheds. Background Art

[0002] Floating film refers to a thin film formed by the floating and aggregation of dead algae and organic matter in aquaculture. Under aeration conditions, the surface tension of bubbles can aggregate dead algae and various organic debris in the water, forming a thicker floating film on the water surface. The floating film will constantly float to the surface or sink into the water in various changes in the water body.

[0003] Floating film has two main hazards to aquaculture. On the one hand, a large amount of floating film covers the surface of the water, hindering the oxygen exchange between water and air; on the other hand, when dead algae and organic debris in the floating film decompose, a large amount of oxygen is consumed, producing a large amount of nitrogen and phosphorus. Moreover, the floating film that sinks to the bottom of the water will form an oxygen debt at the bottom of the water, greatly increasing the risk of aquaculture. As an aggregate of organic matter separated by the aquaculture water body, the timely removal of floating film can reduce the organic matter content of the pond to a certain extent and reduce the risk of aquaculture.

[0004] Before the invention was developed, due to the uncertainty and persistence of the appearance of floating films and the hysteresis of their harmful effects, most farmers ignored the treatment of floating films or only removed them by manual scooping, which was inefficient and ineffective. There is also no cheap, environmentally friendly, time-saving and labor-saving physical method for automatically removing floating films in the industry. Summary of the invention

[0005] In order to solve the above problems, the present invention adopts physical salvage method and air lift principle to separate and collect floating film on the water surface, and develops an automatic salvage device for floating film on the water surface of shrimp shed culture.

[0006] The technical solution of the present invention is:

[0007] The invention discloses an automatic salvaging device for floating film on the surface of a shrimp shed aquaculture water, which is composed of a salvaging propeller (1), a floating film collector (2), a floating film storage device (4), an air lift (8) and a barrier (17). The device is characterized in that the salvaging propeller (1) is connected to a motor (6) through a central shaft (5) and a transmission rod (7), and the floating film collector (2) is connected to the floating film storage device (4) through a rotating buckle (3).

[0008] The floating film collector (2) is provided with a floating film collecting tank (14) which is connected to the reverse air lift pore surface (9).

[0009] The front end of the floating film storage device (4) is provided with a power source (10), the rear end is a floating film storage compartment (12), the side is provided with a floating film storage water outlet (13), and the top is provided with a floating film collection tank top cover (19). A water flow guide groove (15) is provided in the middle of the bottom of the floating film storage device (4).

[0010] The motor (6) is located below the rotating buckle (3) and is connected to the floating film collector (2), and is provided with a propeller.

[0011] The reverse air lift (8) is located above the rotating buckle (3), and its structure from bottom to top includes a bubble generating device (16), a reverse air lift air hole surface (9) and a "U"-shaped pipe (18).

[0012] The U-shaped pipe (18) is provided with an air-lift outlet hole (9), the inlet of which is communicated with the floating film collection tank (14), and the outlet is located above the floating film storage cabin (12).

[0013] The barrier (17) is a long strip of cloth with metal tabs at both ends.

[0014] The advantages of the present invention are as follows:

[0015] 1. Simple operation, convenient and practical, low cost.

[0016] 2. The present invention can realize uninterrupted automatic salvage of the floating film.

[0017] 3. The structure of the salvage propeller can salvage part of the surface water while salvaging the floating film. This part of water is rich in organic matter. When the water body is stirred during the salvage process, the organic matter enriched in the floating film is broken and dispersed into the water body again. Through the air lift effect of reverse air lift, this part of organic matter can be separated again, and excess water can be removed, which improves the efficiency of floating film salvage.

[0018] 4. The design of flexible head and tail rotation allows the machine to automatically turn after hitting the wall, forming a random walking route in the pond. The head of the machine deflects after hitting the wall, the relative position of the water flow guide groove and the motor drainage direction changes, and the water flows out from the gap on the side of the machine, forming a lateral impact force and changing the direction of the machine. After the machine leaves the wall, due to the water flow resistance, the tail returns to the position with the least resistance (consistent with the direction of movement of the head). At this time, the relative position of the water flow guide groove and the motor drainage direction returns to its original state, and the machine continues to move straight.

[0019] 5. If the aquaculture water body is large, or the location of the floating film is relatively concentrated, the machine's activity space can be reduced by using barriers to improve the efficiency of floating film salvage.

[0020] 6. The flat design increases the stability of the floating film salvage device and also increases the salvage area and the volume of the floating film storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] 1. Before using the present invention, you should first check whether the power supply is sufficient, whether the machine body has any water leakage or seepage, and whether the rotating buckle (3) is stuck. When using, just turn on the power switch and put it in the pond. During use, make appropriate inspections to observe whether the salvage machine is working normally and whether there are any unexpected situations such as stranding. After use, remove the power supply and clean the machine in time, especially the salvage propeller (1), the floating film collector (2), the floating film storage (4) and the anti-air lift (8).

[0051] 2. When the pond area is too large or the floating film is relatively concentrated, the barrier (17) can be used to circle the working range of the salvage machine according to the location of the floating film. When in use, unfold the barrier and insert the metal sticks at both ends into the pond bank to circle the working range of the salvage machine, and control the depth of the cloth so that half of it is submerged in the water and the other half is on the water surface. Then put the floating film salvage machine in to improve the salvage efficiency.

[0052] 3. The rotating buckle (3) needs to be lubricated regularly to prevent rust or jamming.
