Description

Technical Field

[0001] The utility model belongs to the technical field of water environment pollution control, and in particular relates to an automatic lifting underwater slow-release medicine positioning and releasing device. Background Art

[0002] The main pollutants that cause eutrophication of water bodies are nitrogen and phosphorus. Usually, phosphorus is removed by adding agents, and nitrogen is removed by denitrification using external carbon sources. Both methods require the input of external agents. With the continuous deepening of research on water denitrification and phosphorus removal agents, a variety of water slow-release agents have appeared on the market, which can be directly added to water bodies for purification. However, the existing slow-release agents are mainly in the form of direct spraying. After the agent is added to the water body, it sinks to the bottom of the water body and is covered by the bottom mud, plants and animals in the water body, affecting the efficiency of the agent. Since the slow-release agent has been added to the water body, the consumption of the slow-release agent cannot be observed from outside the water body. Although the pollutant indicators corresponding to the slow-release agent can appropriately reflect the consumption of the slow-release agent, the pollutant indicators are affected by exogenous pollution, and the slow-release agent has non-target pollutant consumption, so it is impossible to judge the timing of slow-release agent replenishment.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figure 1 As shown, an automatic lifting underwater slow-release agent positioning and releasing device disclosed by the utility model is used for observing and quickly replacing slow-release agents in water bodies, including a positioning frame, a frame structure 6 and a limiting frame.

[0024] The positioning frame includes four vertical positioning rods 1, which vertically form a rectangular positioning frame and are vertically fixed in the water body. The bottom of each positioning rod 1 in the positioning frame is deeply set below the mud surface of the bottom of the water, which is used to position in the water body and provide a stable frame structure.

[0025] The limiting frame is arranged on the positioning frame, and is used to limit the vertical displacement of the frame structure 6. The limiting frame includes an intercepting member 2 and a supporting member 5, which are respectively arranged on the upper and lower sections of each positioning rod 1, and the frame structure 6 is located on the positioning rod 1 between the intercepting member 2 and the supporting member 5, and is used to limit and support the frame structure 6, respectively.

[0026] Furthermore, in the present embodiment, both the intercepting member 2 and the supporting member 5 adopt cross bars. The intercepting member 2 adopts a detachable cross bar to be movably connected to the positioning rod 1, and the supporting member 5 adopts a fixed cross bar to be fixedly connected to the positioning rod 1. The length of the intercepting member 2 and the supporting member 5 is greater than the diameter of the pipe 3, and is used to limit the position of the frame structure 6 connected to the pipe 3 on the positioning frame during the vertical displacement process.

[0027] The outer structure of the frame structure 6 matches the structure of the positioning frame and also adopts a rectangular frame structure. The frame structure 6 adopts a hollow structure. The frame structure 6 is filled with a sustained-release agent, and water can freely enter and exit the frame structure 6, so that the sustained-release agent filled in the frame structure 6 sinks to the bottom of the water body.

[0028] One-piece pipes 3 are welded on the four corners of the frame structure 6. The pipes 3 are hollow in structure, and the number of the pipes 3 is consistent with the number of the positioning rods 1. The frame structure 6 is movably inserted into the positioning rods 1 through the hollow pipes 3. The positioning rods 1 become guide rods for the pipes 3, thereby driving the frame structure 6 to achieve vertical displacement on the positioning rods 1 through the pipes 3.

[0029] Furthermore, in this embodiment, the bottom of the frame structure 6 is connected to an underwater floating body 4 , and the underwater floating body 4 provides buoyancy to the frame structure 6 .

[0030] Furthermore, in this embodiment, the distance H1 from the intercepting member 2 to the highest water level of the water body is 20-50 cm; the distance H2 from the top of the frame structure 6 to the lowest water level of the water body is greater than 30 cm.

[0031] Furthermore, in this embodiment, the bottom of the positioning frame is fixed with a heavy object to the mud surface of the bottom of the water by drilling holes, and the bottom of the positioning frame can also be fixed to the bottom of the water by a heavy object.

[0032] The working principle of the utility model is as follows:

[0033] The positioning frame is fixed to the bottom of the water or to the mud surface of the bottom of the water by heavy objects, the intercepting member 2 is removed, the sustained-release agent is put into the hollow frame structure 6, and sunk into the water body. When the gravity is greater than the buoyancy, the frame structure 6 sinks to the support member 5 of the positioning frame by its own weight, and the support member 5 supports the frame structure 6.

[0034] At this time, the distance H1 between the intercepting member 2 and the highest water level of the water body is 20-50 cm, and the distance H2 between the top of the frame structure 6 and the lowest water level is more than 30 cm.

[0035] Water can freely flow in and out of the frame structure 6, so that the sustained-release medicine filled in the frame structure 6 sinks to the bottom of the water body.

[0036] When 70-90% of the sustained-release agent in the frame structure 6 is consumed, due to the gradual disappearance of its own gravity and the underwater floating block 4 at the bottom of the frame structure 6, the frame structure 6 is guided to slide upward on the positioning rod 1 through the pipe 3, so that the top of the pipe 3 floats to the position of the intercepting member 2 on the upper section of the positioning rod 1 of the positioning frame, and is thereby limited by the intercepting member 2.

[0037] Then the operator can remove the intercepting member 2 from the positioning rod 1 , take out the frame structure 6 from the water body, and refill the sustained-release agent in the frame structure 6 .

[0038] To sum up, when the consumption of the sustained-release agent of the device does not reach the set requirements, the gravity is greater than the buoyancy, and the entire device is supported underwater on the support 5; when the consumption of the sustained-release agent of the device reaches the set requirements, the gravity is less than the buoyancy, and the entire device floats to the intercepting member 2. After the intercepting member 2 is disassembled, the sustained-release agent in the device replenishment frame structure 6 is taken out from the water.

[0039] The utility model is positioned to the plane of the water body by a positioning rod, and utilizes an underwater float arranged at the bottom of the device. When the slow-release agent in the device is consumed, the device is lifted to the water surface by buoyancy, and the slow-release material in the device is replaced in time. The utility model uses a simple structure to achieve the fixed-point release of the slow-release agent and the timely replenishment of the agent. The utility model can replace the consumed slow-release agent in time, and more effectively treat water pollution. The utility model can place the slow-release agent at a specific position at the bottom, which is suitable for treating bottom pollution of water bodies.
