Hydraulic rainwater automatic recovery device

This creation is about a hydraulic rainwater automatic recovery device.

Although there is a lot of rainfall in Taiwan, the area is narrow and long, and there are central mountains in the territory. The area with an elevation of more than 1,000 meters accounts for one-third of the island. Therefore, the terrain changes greatly, the rivers are short and rapid, the slope is steep, and the water flow is urgent. It is not easy to use the rainfall for storage. Most of the rainwater flows into the rivers and oceans after the rain, resulting in a shortage of water resources available to Taiwan. Therefore, the development of rainwater recovery technology can not only effectively reduce urban flooding runoff during heavy rains, but also solve some problems such as lack of water resources. The most convenient way to collect rainwater is to collect rainwater directly from the roof of the building. How to make full use of the rainwater collected on the roof of the building to make up for part of the water resources instead of simply flowing into the drainage ditch has become a very important issue in recent years. .

Due to the fact that dust, leaves or eggs are usually dropped in the catchment area before the rain, the rainwater at the beginning of the rain will be contaminated to a greater extent. According to the literature, the water quality of rainwater SS (suspended solids) and turbidity during the rainfall period will decrease with the increase of the time after the start of rainfall; in addition, the initial rainwater pH value is also higher, and it is charged due to the atmosphere. The particles are also more than usual, resulting in a relatively high conductivity of the initial rainwater. For all of the above reasons, the rainwater at the beginning of the rain is less useful. Therefore, before the rainwater collected is to be reused, the initial rainwater with a large degree of pollution should be removed first, and only the rainwater in the later stage of the rainfall is more practical. value.

The common rainwater recovery device has a relatively simple structure. Generally, only the water pipes are used to collect all the rainwater during the rainy period (for example, the roof of the building), and all the rainwaters are directly collected into the container for storage and use. Exclude the initial rainwater with a high degree of pollution, resulting in receipt The collected rainwater mixes the initial rainwater to reduce its application value and lose the goal of rainwater recycling. Therefore, it was only later that a better rainwater recovery device was developed. It was considered that the initial rainwater with a high degree of pollution was excluded. There was even a better rainwater recovery device, and the rainwater was further purified to include The pollutants are even lower. However, the conventional rainwater recovery devices generally have some shortcomings to be improved, as shown in Table 1.

The above-mentioned shortcomings of the conventional rainwater recovery device can be summarized as the following five major disadvantages: (1) there is no function of intercepting the initial rainwater, and (2) the tank body for storing the initial rainwater has no adjusted elastic space and cannot be automatically operated. . (Note: Because the catchment area and the tank volume of the initial rainwater storage are fixed, that is, only the initial rainwater after a certain cumulative rainfall after rain), (3) the function of further purifying the rainwater quality, ( 4) Use a rainwater purification method that requires frequent removal by the user (for example, a filter that is easy to block or a sedimentation tank that does not have a sludge discharge facility), and (5) requires electricity.

This creation is based on the above five major shortcomings of the conventional rainwater recovery unit. The following are the following: Improvement measures for the shortcomings of “no initial rainwater interception function”: This creation has an initial rainwater interceptor to automatically control the initial rainwater interception mechanism. . After the rain began, the rainwater interceptor intercepted all the dirty initial rainwater and discharged it into the drainage ditch. After the accumulated rainfall reaches the preset value after the rain, the rainwater interceptor starts to operate, and the later clean rainwater is introduced into the subsequent rainwater purification facility for further processing.

Improvement measures for the shortcomings of "the tank with initial rainwater storage does not adjust the elastic space and cannot be operated automatically": The creation of the rainwater interceptor is provided with a rainfall metering tank. The user can flexibly adjust the cumulative interception and rain accumulation according to the actual operation result. The initial rainfall within the rainfall, the cumulative rainfall can be adjusted from 0mm to 19mm. The rainfall metering tank and the floating bulb are open-air type, and the land is utilized. The two important natural phenomena such as rainfall and evaporation in the water cycle of the ball climate system can achieve the automatic operation mechanism even without manual control. According to the literature, the average annual reference evapotranspiration in Taiwan from 1990 to 2004 is about 1.89~4.21mm/d, the north is between 2.04~3.21mm/d, and the south is between 2.00~4.17mm/d. According to the above evapotranspiration and the depth of the float tube part of the artificial rainfall measuring tank, it may take only 10~15 days after the rain to stop, the created rainwater interceptor can be automatically returned to the initial state, which is a humanized design. If it is supplemented by the floating ball tube part, the float cylinder drain valve can be slightly opened, so that it will remain in the drip state normally. The time required for the rainwater interceptor to automatically return to the initial state after rain stop can be shortened to 1~ Within 2 days.

Improvement measures for the shortcomings of "no further purification and treatment of rainwater quality": In addition to the initial rainwater interceptor, this creation has a sedimentation tank to further purify the introduced rainwater.

Improvement measures for the shortcomings of "Using the rainwater purification method that the user needs to remove frequently": The rainwater purification method of the present invention adopts a sedimentation tank, and the sedimentation tank is a inclined pipe (or inclined plate) which has better treatment effect and less head loss. In order to reduce the concentration of suspended solids in the rainwater; and there is a large volume of sludge bucket and mud discharge valve below the sedimentation tank, the user can carry out the mud discharge operation after a long time.

Improvement measures for the shortcomings of "need to use electricity": This creation system uses the height difference between the roof and the ground, the hydraulic operation device, and the principle of natural downward flow by water, without using electricity at all.

This creation is about a hydraulic rainwater automatic recovery device. The main structure includes four parts: rainwater interceptor, flow controller, sedimentation tank and water storage tank. Its rainwater interceptor automatically removes the dirty initial rainwater and intercepts the cleaner rainwater to the subsequent sedimentation tank. The flow controller controls the flow of rainwater flowing into the sedimentation tank to ensure the treatment effect, and the excess rainwater is automatically discharged to the drainage. ditch. The sedimentation tank is made by tilting the pipe (or inclined plate) to reduce the concentration of suspended solids in the rainwater, and the effluent flows into the storage tank for storage. The creation system utilizes the height difference between the roof and the ground, and the hydraulic operation device does not need to use electricity; and the interaction between natural rainfall and evaporation is used to control the upper and lower sides of the float group to achieve automatic interception of rainwater.

Referring to Figure 1, the rain first falls on the roof of the house (50) when it rains, and falls through the eaves (51) along the slope of the roof (50) of the house and falls into the rain gutter (52). The rainwater then flows through the roof downpipe (16) into the created rainwater interceptor (1). The initial rainwater intercepted by the initial rainwater discharge pipe (17) is discharged to the rain drain (53); as for the cleaner rainwater, the rainwater is drained. The shunt tube (18) flows into the flow controller (2), the sedimentation tank (3) and the water storage tank (4) of the present invention in sequence for processing and storage.

Referring to Figure 2, the creation includes a rainwater interceptor (1), a flow controller (2), a sedimentation tank (3), and a water storage tank (4), among which a flow controller (2) and a sedimentation tank (3) And the water storage tank (4) can be combined and disposed in the same tank.

Please also refer to FIG. 3 and FIG. 4, which are part of the creation rainwater interceptor (1). The structure of the rainwater interceptor (1) includes a rain metering tank (11), a float cylinder (12), a float group (13), and a interceptor body (15). The rain metering tank (11) is a flat-shaped box body for collecting the collected rainwater into the floating float cylinder (12), thereby controlling the float ball (131) of the float ball group (13) and the discharge pipe plug head. The up and down movement of (133) achieves the purpose of automatically intercepting the initial rainwater. An adjustable raft (111) is provided at the joint of the rain metering tank (11) and the float cylinder (12), and the adjustable raft (111) is a flat-top raft structure connected to the upper rotating handle by a connecting rod. . The user can adjust the height of the adjustable raft (111) by adjusting the initial rainwater within the accumulated rainfall after the rain is to be adjusted according to the actual operation result. A measuring ruler (112) is provided beside the adjustable seesaw (111), To directly measure the actual height of the flat top slab. The rain metering tank (11) and the float cylinder (12) are both uncapped boxes above and are open-air type, and the rainwater can fall directly into the rain metering tank (11) and the float cylinder (12). There must be no obstructions above. When there is no rain for many days, the water level in the float cylinder (12) will decrease due to natural evaporation. At this time, the float (131) will fall with the water level, and is driven by the float connecting rod (132). The discharge pipe plug (133) in the interceptor body (15) will move upward, and a natural passage is formed between the interceptor body (15) and the initial rainwater discharge pipe (17). If it starts to rain, the dirty initial rainwater flows into the interceptor body (15) from the roof downpipe (16) and is discharged directly from the initial rain drain pipe (17) to the rain drain (53). When it continues to rain for a while After that, the rainwater collected by the rainfall metering tank (11) flows into the float cylinder (12), and the water level in the float cylinder (12) gradually rises, and the float (131) also rises with the water level, by the float The connecting rod (132) drives the discharge pipe plug (133) located in the interceptor body (15) to move downward, and finally the discharge pipe plug (133) will completely cover the initial rainwater discharge pipe (17). The rainwater flowing into the interceptor body (15) will be sequentially processed and stored by the rainwater flow pipe (18) into the flow controller (2), the sedimentation tank (3) and the water storage tank (4). A float tube drain valve (14) is provided below the float tube (12) for draining the rain metering tank (11) and the float tube (12); the float tube drain valve (14) has another The application can be opened normally or slightly, so that the float tube (12) is always in a drip state, which can shorten the time required for the water level of the float tube (12) to drop to the bottom after the rain stop, and make up for the slower evaporation time of the rainwater. The troubles encountered.

Please refer to FIG. 5 and FIG. 6. The two figures are part of the flow controller (2), the sedimentation tank (3) and the water storage tank (4). The flow controller (2) adopts an orifice water inlet mode to control the flow rate into the subsequent sedimentation tank (3) and the water storage tank (4). The flow controller (2) is connected to the sedimentation tank (3) by a plurality of inlet orifices (21), and at least one spare inlet orifice (22) is provided with a detachable spare inlet orifice plug ( 23), can be easily removed, and can immediately expand the flow of recycled rainwater. When heavy rain occurs, if the rainwater flow into the flow controller (2) through the rainwater flow pipe (18) is too large, and the water level in the flow controller (2) exceeds the overflow weir (24), the excess rain will The overflow weir (24) overflows and is discharged to the rain drain (53) via the bypass discharge pipe (25); the flow overflow weir (24) adopts a flat-top raft structure to reduce the possibility of rising when overflowing. Water level. Since the inflow flow controller (2) adopts the design of the orifice plus the weir, it is assumed that the flow rate of the rainwater discharged from the overflow weir (24) is 0 when the flow controller (2) is full of water. All the rainwater flows into the sedimentation tank (3) and its flow rate is Q ₀ . When heavy rain occurs, even if the flow of rainwater discharged from the overflow weir (24) increases from 0 to 10 times Q ₀ , the flow of rainwater flowing into the sedimentation tank (3) will only increase from the original Q ₀ to With a Q _{0 of} about 1.05 times, the design of the orifice and the weir can be used to control the flow of rainwater flowing into the sedimentation tank (3) to a small variation range to ensure the effect of the rainwater purification treatment.

Please refer to FIG. 5 and FIG. 6 again, wherein the sedimentation tank (3) is provided with an inclined pipe (or inclined plate) (31) with better sedimentation effect, and the removed suspended solids will settle and temporarily store in a large volume. In the sedimentation tank sludge bucket (33); the cleaned rainwater is discharged from the sedimentation tank effluent (32) to the storage tank (4) for storage. A sedimentation tank sludge discharge valve (34) is arranged below the sedimentation tank sludge bucket (33), and the user can periodically discharge the sludge in the sedimentation tank to the rainwater drainage channel (53) to maintain the sedimentation tank (3). Processing effect. There is also a water storage tank drain valve (41) below the water storage tank (4), which can be used for drainage when the user regularly cleans the water storage tank (4); if the user intends to additionally expand the additional water storage tank body, the water storage tank The drain valve (41) can also be used as a coupling line to connect the additional water reservoir body. The tank cover (35) is provided in the opening part above the tank such as the flow controller (2), the sedimentation tank (3) and the water storage tank (4), which can be used for normal inspection and maintenance by the user, or Ensure the recovery of rainwater The quality is not contaminated.
