Description

Technical Field

[0001] The invention relates to a technology for breeding livestock in batches, in particular to a rainproof system for an open-air sewage pool and a control method thereof. Background Art

[0002] Reduction is the key to reducing the cost of sewage treatment. Some livestock farms set up large-scale sewage storage tanks with an area of ​​hundreds to tens of thousands of square meters in the open air to store sewage. When it rains heavily, a large amount of rainwater will be received in the open-air sewage storage tank, and a large amount of rainwater will be mixed into the sewage, which greatly increases the amount of sewage treatment and increases the cost of sewage treatment. Year after year, it is a huge expense. This is a great burden for enterprises. As long as the rainwater is separated and the "rainwater and sewage diversion" on the surface of the sewage pool is realized, the sewage treatment cost increased by the mixing of rainwater can be saved from the source. According to conventional ideas, can a rain shelter be built? However, the cost and difficulty of building a rain shelter over a large sewage pool are very high. Therefore, how to remove rainwater that falls into the open-air sewage pool when it rains is an urgent problem to be solved.

[0003] In order to solve the above problems, the patent document with announcement number CN106854896B proposes an inflatable film-type covering device, which can realize a technical solution of covering an open-air sewage pool and pumping out rainwater when necessary.

[0004] However, the above patent document has defects. For example, the film needs to be inflated in the system, and it takes time to inflate a large-area film system. In addition, the system maintenance is also very cumbersome. If there is a leak, the entire film system may fail. Summary of the invention

[0005] In order to prevent rainwater from entering the sewage in the open-air sewage pool on rainy days and to timely and effectively drain the rainwater from the water surface of the open-air sewage pool, the present invention proposes a rainproof system for the open-air sewage pool and a control method thereof.

[0006] The purpose of the present invention is achieved through the following technical solutions: A rainproof system for an open-air sewage pool, comprising an open-air sewage pool (1), and also comprising a pair of guide rails (2) symmetrically arranged on the banks of the sewage pool (1) on both sides; a walking trolley (3) arranged on the guide rails (2) on both sides and reciprocating along the guide rails (2); a waterproof membrane roll (4) is mounted on the walking trolley (3) on both sides, one end of the waterproof membrane roll (4) is fixed to the beginning of the guide rail (2), and the other end of the waterproof membrane roll (4) is gradually unfolded toward the end of the guide rail (2) as the walking trolley (3) moves.

[0007] In the rainproof system of the open-air sewage pool, the guide rail (2) is arranged to be inclined toward the ground with a slope of 1% to 10%. In this way, when the walking vehicle (3) travels to the end of the track and the waterproof membrane roll (4) is fully unfolded, the waterproof membrane roll (4) forms an inclined slope due to the inclination of the guide rail (2), and the inclined slope is used to guide the flow of rainwater.

[0008] The rain protection system of the open-air sewage pool is provided with a drainage ditch (5) at the end of the guide rail (2), and the drainage ditch (5) is located below the end of the walking trolley (3).

[0009] In the rainproof system of the open-air sewage pool, the waterproof membrane roll (4) is made of polyvinyl chloride or high-density polyethylene with a thickness of 0.25 mm.

[0010] The rainproof system for the open-air sewage pool has edge ropes on both sides of the waterproof membrane roll (4), specifically edge ropes arranged along the direction of the guide rail (2). The edges of the waterproof membrane roll (4) are rolled and bonded to each other, thereby wrapping the edge rope inside. The edge rope has the function of windproofing and tensioning, and is made of steel wire rope or steel strand rope.

[0011] The control method of the rain protection system of the open-air sewage pool comprises a rainfall sensor and a wind speed sensor, a controller, i.e., a PLC or a single-chip microcomputer, a power supply system and an actuator; and also comprises a user interface with a preset program; and specifically comprises the following steps: Step 1: Monitor rainfall and wind speed in real time by installing rain sensors or wind speed sensors around the sewage pool; Step 2: Transmit the monitored rainfall and wind speed data to the PLC or single chip microcomputer; Step 3, the PLC or single-chip computer determines whether it is necessary to start the extension and retraction action of the rainproof awning according to the preset threshold value: when the starting conditions are met, the PLC or single-chip computer sends a control instruction to the motor driver, driving the motor to drive the telescopic rod to extend and retract, thereby changing the covering area of ​​the rainproof awning; Step 4: The motor driver of the actuator receives the control instruction of the PLC or the single-chip microcomputer, drives the motor to rotate forward or reverse, and makes the walking trolley move along the guide rail, thereby realizing the expansion or contraction of the waterproof film roll; Step 5: The motor driver feeds back the status of the waterproof membrane roll, including the position and the unfolding speed, to the PLC or the single-chip microcomputer for real-time monitoring and adjustment.

[0012] The control method of the rain protection system of the open-air sewage pool also includes manual backup. In the event of power failure or failure of the automatic control system, a manual operating lever can be set to manually control the walking movement of the walking trolley.

[0013] As can be seen from the above, the present invention proposes a traveling trolley with a waterproof film roll that is guided by a guide rail and driven by a motor. In this way, when it rains, the covering work of the open-air sewage pool can be automatically realized through the control system. At the same time, through the anti-seepage membrane with a slope, rainwater can be conveniently guided into the drainage ditch for discharge.

[0014] It can be seen that compared with the waterproof membrane in the prior art that needs to be inflated, the present invention has a more compact structure, is easy to install and maintain; in this way, rainwater in the open-air sewage pool can be discharged outside the pool to achieve "rainwater and sewage separation", which will not significantly increase the capacity of the sewage pool and the processing time of the corresponding sewage treatment equipment, thereby greatly reducing the additional processing costs caused by rainwater entering the open-air sewage pool and reducing the burden on related enterprises and related farms.

Among them, the shape of the waterproof film roll 4 after being fully unfolded can vary according to the shape of the sewage pool 1. For example, if the sewage pool is a quadrilateral, the waterproof film roll 4 has a corresponding shape and can completely cover the sewage pool 1.

[0018] Furthermore, in the rain protection system of the open-air sewage pool, the guide rail 2 is inclined underground with a slope of 1% to 10%. In this way, when the walking trolley 3 travels to the end of the track and the waterproof membrane roll 4 is fully unfolded, the waterproof membrane roll 4 forms an inclined slope due to the inclination of the guide rail 2, and the inclined slope is used to guide the flow of rainwater.

[0019] A drainage ditch 5 is provided at the end of the guide rail 2, and the drainage ditch 5 is located below the end of the traveling trolley 3; thus, rainwater guided to the edge of the waterproof membrane will fall into the drainage ditch 5, so as to be subsequently collected into the municipal pipe network.

[0021] In the above-mentioned rainproof system for an open-air sewage pool, the walking trolley 3 can be driven by a servo motor, which is controlled by a PLC through a motor controller. At the same time, the waterproof membrane roll 4 is placed on the walking trolley 3 in the form of a reel, a roller and a roller seat. The control method of the rain protection system of the open-air sewage pool comprises a rainfall sensor and a wind speed sensor, a controller, i.e., a PLC or a single-chip microcomputer, a power supply system and an actuator; and also comprises a user interface with a preset program; and specifically comprises the following steps: Step 1: Monitor rainfall and wind speed in real time by installing rain sensors or wind speed sensors around the sewage pool; Step 2: Transmit the monitored rainfall and wind speed data to the PLC or single chip microcomputer; Step 3, the PLC or single-chip computer determines whether it is necessary to start the extension and retraction action of the rainproof awning according to the preset threshold value: when the starting conditions are met, the PLC or single-chip computer sends a control instruction to the motor driver, driving the motor to drive the telescopic rod to extend and retract, thereby changing the covering area of ​​the rainproof awning; Step 4: The motor driver of the actuator receives the control instruction of the PLC or the single-chip microcomputer, drives the motor to rotate forward or reverse, and makes the walking trolley move along the guide rail, thereby realizing the expansion or contraction of the waterproof film roll; Step 5: The motor driver feeds back the status of the waterproof membrane roll, including the position and the unfolding speed, to the PLC or the single-chip microcomputer for real-time monitoring and adjustment.

[0022] The control method of the rain protection system of the above-mentioned open-air sewage pool should also include manual backup. In the event of power failure or failure of the automatic control system, a manual operating lever can be set to manually control the walking movement of the walking trolley.

[0023] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
