Description

TECHNICAL FIELD

In recent years, a large area of water bodies in China need to be comprehensively managed and regulated in terms of controlling pollution sources and restoring ecological systems. The water body restoration methods include aeration, filtration and sedimentation, etc. The above methods can effectively remove harmful substances such as particulate matter, suspended matter and dissolved matter in water bodies.

[0003] At present, the most commonly used method for water body restoration is aeration. Aeration refers to the process of forcibly transferring oxygen in the air to the water body to be restored. Oxygen in the air is combined with microorganisms and ions in the sewage to remove harmful substances in the sewage, so that the water body has enough dissolved oxygen. The traditional aeration equipment sprays the water body in the air, and a certain amount of oxygen is brought into the water body at this time. This aeration method is simple, and the aeration efficiency is generally low. When a large amount of water body to be restored needs to be treated, the water body needs to be repeatedly lifted and sprayed in the air to contact with the air. Although this can increase the contact area between the water body and the air, the water body in the upper half can dissolve more oxygen in the air, and the water body in the lower half contacts with the air less, so that the oxygen cannot be uniformly dissolved into the water body, resulting in inconsistent restoration degree of the water body.

The fixed shaft 2 is vertically arranged in the box 1, the two ends of the fixed shaft 2 are respectively connected with the top and the bottom inside the box 1, and the fixed shaft 2 is located at the center position of the box 1; the gas conveying structure 3 is used for conveying air into the box 1, mainly conveying oxygen into the box 1, so that the oxygen is dissolved in the water body in the box 1, and the water body is facilitated to be repaired, the gas conveying structure 3 comprises a gas conveying pipe 31 and a gas supply assembly, the gas conveying pipe 31 is in communication with the output end of the gas supply assembly, the gas supply assembly comprises a container containing gas and a gas pump arranged in the container, the output end of the gas pump is in communication with one end of the gas conveying pipe 31, the gas in the container can be conveyed into the gas conveying pipe 31, the gas conveying pipe 31 is sleeved on the fixed shaft 3, a plurality of through holes 32 are formed in the side wall of the gas conveying pipe 31, and the through holes 32 are in communication with the container containing the gas. Figure 1 As can be seen from the figure, the gas conveying pipe 31 is a section pipe, and the gas in the gas conveying pipe 31 can be conveyed into the box 1 through the plurality of through holes 32; the driving structure 4 has an output end, the output end of the driving structure 4 is connected with the gas conveying pipe 31, and the driving structure 4 is used for driving the gas conveying pipe 31 to slide on the fixed shaft 2. When the present application is used, the gas supply assembly is used for conveying gas (with a high oxygen content) into the gas conveying pipe 31, the gas in the gas conveying pipe 31 is conveyed into the box 1 through the plurality of through holes 32, and the water body in the box 1 can be repaired, and meanwhile, the device is further provided with the driving structure 4, which can drive the gas conveying pipe 31 to slide on the fixed shaft 2, that is, to slide up and down along the height direction of the fixed shaft 2, so that the gas in the gas conveying pipe 31 can be uniformly conveyed into the box 1 through the plurality of through holes 32 along with the sliding of the gas conveying pipe 31, and a certain amount of air can be conveyed into the water body in the box 1 from top to bottom, so that the repair degree of the water body is consistent.

[0040] Further, the gas conveying pipe 31 comprises: a pipe body 311, a cross rod 312, a through port 313, and a one-way valve 314. The cross section of the pipe body 311 is annular, the pipe body 311 is sleeved on the fixed shaft 3, the pipe body 311 corresponds to an annular sleeve, has an inner ring side wall and an outer ring side wall, and the gas is input into the cavity between the inner ring side wall and the outer ring side wall, and the plurality of through holes 32 are respectively formed in the outer circumferential direction of the pipe body 311, that is, in the outer ring side wall of the pipe body 311. Figure 3 As shown, the plurality of cross rods 312 are arranged in an annular array horizontally in the circumferential direction of the pipe body 311, and one end of each cross rod 312 is in communication with the plurality of through holes 32. Figure 1As can be seen, the horizontal rod 312 is horizontally arranged in the box body 1, a plurality of through holes 313 are arranged on the horizontal rod 312, and a one-way valve 314 is arranged at the through hole 313.

The one-way valve 314 is arranged at the through hole 313, so that the gas can only be discharged to the through hole 313.

[0041] Further, the fixed shaft 2 is rotationally connected with the box body 1. The embodiment provides an implementation manner of a specific driving structure 4. The driving structure 4 includes a driving member 41 arranged at the bottom of the box body 1. The output end of the driving member 41 is fixed with the bottom end of the fixed shaft 2. The driving member 41 is used for driving the fixed shaft 2 to rotate. The driving member 41 can be a motor, a rudder or other rotating driving structure. The fixed shaft 2 is a screw rod. The pipe body 311 is sleeved on the fixed shaft 2 and is threadedly connected with the fixed shaft 2. The working principle of the driving structure 4 is as follows: the driving member 41 works to drive the fixed shaft 2 to rotate. Since the fixed shaft 2 is a screw rod and the pipe body 311 is threadedly connected with the fixed shaft 2, when the fixed shaft 2 rotates, the pipe body 311 can be driven to move up and down on the fixed shaft 2, so that the driving structure 4 drives the gas conveying pipe 31 to move on the fixed shaft 2. The rotating direction of the fixed shaft 2 is changed to change whether the gas conveying pipe 31 moves upward or downward on the fixed shaft 2.

[0042] In order to avoid that the pipe body 311 rotates with the fixed shaft 2, further, a plurality of sliding grooves 11 are arranged on the inner wall of the box body 1. The plurality of sliding grooves 11 are arranged along the height direction of the box body 1. The one end of the plurality of horizontal rods 312 away from the pipe body 311 is respectively slidably connected with the plurality of sliding grooves 11. The plurality of sliding grooves 11 correspond to the plurality of horizontal rods 312 respectively. The plurality of sliding grooves 11 are also arranged in the box body 1 in a ring array. The box body 1 is a cylindrical cavity. When the driving member 41 drives the fixed shaft 2 to rotate, the horizontal rod 312 is limited by the sliding groove 11. Since the sliding groove 11 is arranged along the height direction of the box body 1, the pipe body 311 can be guided and the pipe body 311 can be prevented from rotating with the fixed shaft 2.

[0043] Embodiment 2

[0044] As a further improvement based on embodiment 1, in order to make the oxygen repair the water body more evenly, the sliding block 12 is slidably connected in the chute 11, the sliding block 12 is a cylinder, one end of the sliding block 12 away from the chute 11 is fixed with one end of the horizontal rod 312, the other end of the horizontal rod 312 is rotatably connected with the side wall of the pipe body 311, the horizontal rod 312 can rotate relative to the pipe body 311, as shown in Figure 2 The device further comprises a rack 13 and a gear 14. Two racks 13 are symmetrically arranged on both sides of the chute 11, and the rack 13 is arranged along the length direction of the chute 11; the gear 14 is fixedly sleeved on the circumference of the sliding block 12, and the gear 14 is engaged with the two racks 13 respectively. It has been proposed in embodiment 1 that the driving member 41 of the device can drive the pipe body 311 and the horizontal rod 312 to move up and down on the fixed shaft 2, which is equivalent to giving the horizontal rod 312 a force to move up and down in the chute 11. When the horizontal rod 312 moves up and down, it drives the sliding block 12 to move in the chute 11, and the gear 14 is sleeved on the sliding block 12 and engaged with the two racks 13. Therefore, when the horizontal rod 312 moves up and down, it can drive the gear 14 to rotate and move up and down on the two racks 13. The rotation of the gear 14 drives the sliding block 12 and the horizontal rod 312 to rotate, so that the gas is input into the box body 1 along with the rotation of the horizontal rod 312, and the gas can be more evenly delivered into the box body 1.

[0045] In order to enhance the repair effect, further, the circumference of the horizontal rod 312 is provided with a plurality of stirring rods 315. Because the rotation of the gear 14 can drive the sliding block 12 and the horizontal rod 312 to rotate, so that the stirring rods 315 on the horizontal rod 312 also rotate together, which can stir the water body in the process of introducing air into the box body 1, so that the oxygen can be more fully and evenly mixed into the water body, and the repair effect of the water body is enhanced.

[0046] Among them, the other structures of the embodiment are consistent with embodiment 1, only the optimization of embodiment 1 is made.
