[0038] Example

[0039] Please refer to Figure 1 and Figure 2As shown, the present embodiment provides a tailwater collection and discharge system, including a water collecting tank 10, a water inlet pipe 20, a water pump 30, a water outlet pipe 40 and a control device 50. The water collecting tank 10 is cast and pre-buried in the ground, and the top surface opening of the water collecting tank is located outside the ground; the water inlet pipe 20 is connected to the top of the water collecting tank; at least one water pump 30 is provided, and the water pump 30 is arranged on the bottom surface of the water collecting tank; one end of the water outlet pipe 40 is arranged at the water outlet of the water pump 30, and the other end of the water outlet pipe 40 is led out from the top of the water collecting tank and arranged outside the ground; the control device 50 is independently arranged, and the water pump 30 is electrically connected to the control device 50.

[0040] In this embodiment, the control device 50 may be a sealed box or a cabinet structure, and a device with a power supply and a chip installed inside, and the chip may be a 51 series single chip microcomputer, or a PLC of Siemens' S7-200, S7-300 or S7-1200, etc. Therefore, the water pump 30 can be turned on or off for operation by the control device 50.

[0041] Specifically, the water collecting tank 10 is buried underground by pre-embedding, so that the height of the internal horizontal surface of the water collecting tank 10 is lower than the water collection area, so that the water inlet pipe 20 can transport water into the water collecting tank 10 for storage. At the same time, the pre-embedding can be formed on the water collecting tank 10 by pouring reinforced concrete to provide a stable water collecting tank 10 structure and improve the service life of the water collecting tank 10.

[0042] The water entering the water collection tank 10 can be pumped out of the water collection tank 10 through the water outlet pipe 40 by the water pump 30 (the water pump 30 can be a submersible pump 30), and then can be used to directly irrigate green plants, or can be led out through a water pipe for flushing toilets or washing cars. The opening and closing of the water pump 30 can be controlled by the control device 50, that is, the water pump 30 is powered on or off by a switch to control the start and stop of the water pump 30. In addition, the control device 50 can be independently installed on the bottom surface for operation, which provides convenience for use.

[0043] Specifically, multiple water pumps 30 can be set, and at least one water pump 30 can be set as a backup water pump 30 to ensure that the tail water collection and discharge system can operate normally through the backup water pump 30 in response to sudden damage to the water pump 30, and can be repaired afterwards, thereby improving practicality.

[0044] Furthermore, if Figure 2As shown, in this embodiment, a plurality of branch pipes 201 are arranged on the water inlet pipe 20 for diversion, and a valve 202 is arranged on the branch pipe 201. Each branch pipe 201 can be connected to a water collecting tank 10, so that a plurality of water collecting tanks 10 are formed to store water, so that a corresponding number of water collecting tanks 10 can be installed according to the actual water volume in the catchment area, or a corresponding number of water collecting tanks 10 can be installed according to the needs, and at the same time, the efficient use of water resources in the area can be improved.

[0045] like Figure 1 and Figure 2 As shown, the water collecting tank 10 in this embodiment includes a tank body 101, a cushion layer 102 cast and located on the ground outside the tank body 101, and a hardened layer 103 cast and located on the top surface of the tank body 101, and a well gate 1031 connected to the top surface opening of the tank body 101 is arranged on the hardened layer 103; a water inlet interface 1011 connected to the water inlet pipe 20 is arranged on the top of the tank body 101; and a channel 1032 for leading out the water outlet pipe 40 is pre-buried on the hardened layer 103.

[0046] Specifically, the hardening layer 103 and the cushion layer 102 are both structures cast with reinforced cement, forming the effect of clamping and installing the upper and lower ends of the tank body 101, so as to ensure the structural stability of the pre-buried installation of the water collecting tank 10. Furthermore, a well gate 1031 and a channel 1032 for pipelines and power lines to the ground will be reserved on the hardening layer 103 to facilitate the connection of pipelines. The water inlet pipe 20 can be directly connected to the water inlet interface 1011 to transport water to the tank body 101. In order to set the outlet position of the water outlet pipe 40, it can be designed by reserving a pipeline in the hardening layer 103, so that the water outlet pipe 40 extends through the channel 1032 of the hardening layer 103, and the water source is output at the artificially set position. Similarly, the lead-out position of the power line can also be set by the hardening layer 103, so that the power line and pipeline can be arranged more conveniently on the bottom surface, thereby improving the convenience of use.

[0047] Furthermore, if Figure 2 and Figure 3 As shown, in this embodiment, a manhole cover 1033 is arranged on the top opening of the manhole gate 1031, and the horizontal plane where the top surface of the manhole gate 1031 is located is higher than the ground. The setting of the manhole gate 1031 is convenient for setting the height of the manhole gate 1031 and the opening size of the tank body 101, and then the manhole cover 1033 is used to cover the opening of the manhole gate 1031, thereby improving the safety of the pre-embedded setting.

[0048] Specifically, the well gate 1031 is arranged higher than the bottom surface, so that the position of the well gate 1031 is known, and it is convenient for the operators on the ground to find the tank body 101. At the same time, by installing the well cover 1033, the relatively heavy well cover 1033 is not easy to be opened, thereby improving safety.

[0049] Furthermore, in this embodiment, the tank body 101 is a fiberglass tank or a reinforced cement casting tank, which has good acid and alkali resistance, is environmentally friendly and has a long service life, has the advantages of no leakage and low cost.

[0050] like Figure 2 and Figure 3 As shown, in this embodiment, a rope 301 for arranging a power line is provided between the water pump 30 and the well gate 1031, and a power line channel 1032 penetrating to the ground is provided on the well gate 1031. The rope 301 may be a steel rope, which is convenient for winding the power line around the rope 301, and the rope 301 has a certain protective effect on the power line, and is not easy to be pulled and broken; at the same time, the water pump 30 can also be placed in or taken out of the water collection tank 10 through the rope 301, which improves the convenience of use.

[0051] like Figure 2 As shown, in this embodiment, a first high water level alarm 60 is provided at the top of the tank body 101, and a second low water level alarm 61 is provided at the bottom of the tank body 101. The first alarm 60 and the second alarm 61 are electrically connected in parallel to the control device 50. The first alarm 60 and the second alarm 61 are water level alarms, which are water level alarms that alarm the water level mechanically or by magnetic induction. They can use sound and light alarms or magnetic alarms to simultaneously control the start or stop of equipment such as the water pump 30. For example, the model of the water level alarm can be a ZSB127 water level alarm.

[0052] Specifically, the first alarm 60 and the second alarm 61 can be used to know whether the water level in the tank 101 is too high or too low, thereby forming a monitoring effect on the water level of the tank 101, preventing the water in the tank 101 from overflowing, or the water level in the tank 101 is low, resulting in the idling of the water pump 30. The tailwater collection and discharge system is operated safely during operation, and the safe operation of the water pump 30 is ensured.

[0053] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
