Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, and in particular to a rainwater harvesting tank. Background Technology

[0002] When separating cement from wastewater in a cement kiln, a rainwater collection tank is used to separate cement from the discharged wastewater. However, the water level in existing rainwater collection tanks is not easy to control. Therefore, a new type of rainwater collection tank is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a rainwater collection tank, comprising a bottom slab, a top slab, side walls, and several columns. The top slab has an access hole. The collection tank is made of reinforced concrete and has one underground floor, with a seismic fortification intensity of 8 degrees. Inside the initial rainwater tank, there are rainwater monitoring wells and rainwater interception wells arranged in parallel. Between the rainwater monitoring wells and the rainwater interception wells, there is a gate opening 2 for installing a gate. The rainwater interception wells have a gate opening 3 that penetrates the interior of the initial rainwater tank for installing a gate. The outer wall of the rainwater monitoring wells has a gate opening 4 for installing a gate.

[0004] Furthermore, the interior of the collection pool is divided into an initial rainwater pool and an emergency water pool by a partition made of side walls. The partition is provided with gate openings for installing gates. The bottom plates at both ends of the gate openings are recessed, and there are two access holes located at the top of the initial rainwater pool and the emergency water pool, respectively.

[0005] Furthermore, an ultrasonic level gauge is installed on the top plate, and the ultrasonic level gauge is equipped with an alarm level line.

[0006] Furthermore, a valve well 2 is provided on the side of the initial rainwater tank away from the rainwater interception well. Two flexible waterproof sleeves 2 are provided between the valve well 2 and the initial rainwater tank. A flexible waterproof sleeve 1 is provided on the outer wall of one side of the valve well 2.

[0007] Furthermore, the rainwater monitoring well is equipped with a rainwater ditch.

[0008] Furthermore, a valve well is located on the top plate directly above the gate opening.

[0009] Furthermore, the outer wall of the rainwater interception well is provided with a reserved hole. Beneficial effects

[0010] Wastewater is discharged through the manhole and undergoes cement separation through a sludge treatment system consisting of a collection tank. The collection tank is made of reinforced concrete and has one underground floor. The building is 3.5 meters high and has a seismic fortification intensity of 8 degrees.

[0011] Gates 914.05 and 914.06 at gate tunnels 3 and 2 are normally closed. As rainwater is collected, when the water level in the rainwater interception well rises to -1.30 meters, gate 914.05 at gate tunnel 3 opens, allowing rainwater to flow into the initial rainwater pool. After collecting initial rainwater for 15 minutes, gate 914.05 at gate tunnel 3 closes, and gate 914.06 at gate tunnel 2 opens, allowing initial rainwater to flow from the rainwater interception well into the rainwater monitoring well. When the water level in the rainwater monitoring well rises to -1.00 meters, gate 914.08 at gate tunnel 4 opens, allowing the initial rainwater in the rainwater monitoring well to flow into the rainwater ditch. Gate 914.08 at gate tunnel 4 automatically resets (closes) after 24 hours. An alarm is triggered when the water level in the rainwater monitoring well rises to -0.60 meters.

[0012] Ultrasonic level gauges are used to monitor water levels.

[0013] The second section of the flexible waterproof sleeve is 1.8 meters below ground level. The sludge from the wastewater treatment system is discharged into the kiln for incineration from one section of the flexible waterproof sleeve.

[0014] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description
