Description

Technical Field

[0001] The utility model belongs to the technical field of discharge devices, and more specifically, relates to a rainwater isolation and discharge device for a salt pond. Background Art

[0002] During the seawater salting process, the seawater undergoes multiple stages of evaporation and concentration before entering the crystallization pond. The concentrated brine in the crystallization pond must be protected from dilution by rainwater. A common practice is to cover the pond with a single sheet of plastic sheeting before a rain event. The sheeting is then elevated around the edges to allow rainwater to fall onto the sheeting. After the rain, the water is drained away from the sheeting.

[0003] Based on the above, the inventors discovered the following problem: Typically, rainwater drainage is done by manually removing a small section of a plastic hook raised at the edge of the plastic sheet and lowering this section down to a drain hole, allowing the rainwater to drain through the hole. However, this method requires manual operation and is not easily automated.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a rainwater isolation and discharge device for salt ponds is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0030] Example:

[0031] As attached Figure 1 To the attached Figure 4 As shown:

[0032] The utility model provides a rainwater isolation and discharge device for a salt pond, comprising a first mounting frame 1, a mounting rod 2 being mounted on the surface of the first mounting frame 1, a controller 3 being mounted on the surface of the upper end of the mounting rod 2, the first mounting frame 1 being mounted with a second mounting frame 5 via a lifting mechanism 4, a water suction pipe 6 being mounted on the surface of the second mounting frame 5, a sleeve 7 being sleeved on the surface of the water suction pipe 6, the sleeve 7 being slidable on the water suction pipe 6, a water collecting tray 8 being mounted on the sleeve 7 via a fixing part, a limiting plate 9 being mounted on the surface of one end of the water suction pipe 6 below the sleeve 7, a drainage mechanism 10 being mounted on the end of the water suction pipe 6 away from the limiting plate 9, a sensor 11 being mounted on the bottom of the water collecting tray 8, and the sensor 11 being electrically connected to the controller 3.

[0033] Among them, the lifting mechanism 4 includes a four-link bracket 401 movably connected to the first mounting frame 1, a connecting rod 403 is installed on the surface of the four-link bracket 401, and also includes an electric push rod 402 movably connected to the mounting rod 2, the output end of the electric push rod 402 is movably connected to the connecting rod 403, and the bottom of the first mounting frame 1 is connected to the second mounting frame 5.

[0034] In which, the drainage mechanism 10 includes a connecting hose 1001 installed at one end of the suction pipe 6, and a drainage pipe 1002 is installed at one end of the connecting hose 1001. It also includes a water collecting bottle 1003 and an air pump 1004 installed on the mounting rod 2 through a fixing part. The surface of the commanding height of the drainage pipe 1002 is connected to one end of the first pipe 1005, and the other end of the first pipe 1005 is connected to the water collecting bottle 1003. The water collecting bottle 1003 is connected to one end of the second pipe 1006, and the other end of the second pipe 1006 is connected to the air pump 1004. It also includes a water level sensor 1007 installed at the bottom end of the surface of the second pipe 1006, and the water level sensor 1007 is electrically connected to the controller 3.

[0035] The second mounting frame 5 and the water suction pipe 6 are fixed via a clamp 12 .

[0036] Among them, placement frames 13 are installed on both sides of the water collecting tray 8. By using the placement frames 13, the counterweight can be increased.

[0037] Wherein, a rubber pad 14 is installed at the bottom of the limiting plate 9.

[0038] The rubber pad 14 can improve the sealing performance of the contact between the limiting plate 9 and the water collecting tray 8 .

[0039] When the limiting plate 9 contacts the sleeve 7 , the distance between the limiting plate 9 and the bottom end surface of the water collecting tray 8 is 5 cm.

[0040] The specific usage and function of this embodiment are as follows:

[0041] First, install the first mounting bracket 1 in the appropriate location. Then, install the connecting hose 1001 and drain pipe 1002, and place drain pipe 1002 into the drainage channel. Note that the drainage channel is equipped with a water puddle. Before it rains, after placing the plastic sheeting over the brine, the electric push rod 402, under the control of the controller 3, extends, driving the four-link bracket 401 downward, thereby driving the suction pipe 6 and the water collection pan 8 downward. When the bottom of the pan contacts the plastic sheeting, the sensor 11 generates a signal. After receiving the signal, the controller 3 controls the electric push rod 402 to continue moving downward a distance slightly greater than the height of the water collection pan 8 to ensure that the water collection pan 8 is completely pressed below the floating surface of the plastic sheeting on the brine. At this point, since there is no water in the water collection pan 8, it is subject to the buoyancy of the brine through the plastic sheeting. This buoyancy is greater than the gravity of the water collecting tray 8 plus the counterweight of the water collecting tray 8. Therefore, the buoyancy pushes the bottom of the water collecting tray 8 to the bottom of the water suction pipe 6, thereby blocking the bottom of the water suction pipe 6.

[0042] After a rainstorm, rainwater remaining on the plastic sheeting flows into the water collection pan 8. The added weight of water in the water collection pan 8, combined with the weight of the water collected on the plastic sheeting and its counterweight, overcomes the buoyancy of the water collection pan 8. At this point, the water collection pan 8 descends. After the bottom of the water collection pan 8 clears the bottom of the suction pipe 6 by approximately centimeters, it is restrained by the stop plate 9 and prevents it from descending any further. Because the bottom of the water puddle is lower than the drain pipe 1002, some water will always remain in the puddle and cannot be drained away. This allows the lower end of the drain pipe 1002 to be immersed in this water. Rainwater is present at the bottom of the suction pipe 6, while the bottom of the drain pipe 1002 is also immersed in the water in the puddle. Thus, both ends of the drain pipe 1002, consisting of the suction pipe 6, drain pipe 1002, and connecting hose 1001, are submerged in water, with only a section of air in the middle. At this point, the controller 3 activates the air pump 1004 to remove air from this section of the pipe. The volume occupied by air in the pipeline is filled by rainwater from the water collection tray 8 at the bottom of the suction pipe 6 and water from the puddle at the bottom of the drain pipe 1002. Once all the air is removed, the entire pipeline is completely filled with water. At this point, as the air pump 1004 continues to pump air, water also enters the first pipe 1005. At this point, the water level sensor 1007 installed at the bottom of the first pipe 1005 promptly senses the water and sends a signal to the controller 3, which then shuts off the air pump 1004 to stop pumping air. At this point, the entire pipeline consisting of the suction pipe 6, the connecting hose 1001, and the drain pipe 1002 is completely filled with water, forming a communicating vessel. Due to the siphon effect, rainwater begins to drain through the pipeline. This design eliminates the need for manual pressure on the edge of the plastic sheet; only the water collection tray 8 needs to be raised and lowered, facilitating automation. Furthermore, drainage does not require electrical power; the small air pump 1004 simply removes the air during initial startup to achieve siphon-type automatic drainage, saving energy.

[0043] After the rain stops or the intensity of the rain decreases, as the drainage proceeds, the rainwater layer on the plastic sheet gradually becomes thinner, and the speed at which the rainwater accumulates in the water collection pan 8 slows down. If the accumulation speed is slower than the drainage speed, the rainwater in the water collection pan 8 will gradually decrease. At this time, the gravity of the water collection pan 8 decreases. When the gravity of the water collection pan 8 is less than the buoyancy of the water collection pan 8, the water collection pan 8 will float upward. The outlet of the water suction pipe 6 will be blocked by the bottom of the water collection pan 8. Drainage will temporarily stop. The above design can prevent air from entering the drain pipe 1002 and causing the siphon to fail.

[0044] After drainage stops, the rainwater continues to accumulate in the water collection pan 8. When the accumulated water increases again and the gravity of the water collection pan 8 is greater than the sum of the buoyancy and the suction force of the pipe opening at the bottom of the pan, the water collection pan 8 will move downward again, reopening the water suction pipe 6 and continuing to drain. The above process is repeated until all the rainwater is drained and no more rainwater accumulates, and the drainage process ends.
