Description

Technical Field

[0001] This invention relates to the field of automatic water-blocking devices for hydropower plant buildings, specifically an automatic water-blocking system and its operation method. Background Technology

[0002] A large hydropower station's powerhouse contains restrooms and emergency oil tank operating rooms. Due to heavy rain and poor drainage, these areas pose a risk of backflow. Currently, the main method used is manual drainage. When backflow is detected, waterproof sandbags and water-blocking boards are used for manual drainage. However, if backflow is not detected in time, the water flow will quickly spread to surrounding electrical equipment, causing short circuits and shutdowns, seriously affecting the safe and stable operation of the power station's generating units. Summary of the Invention

[0003] To address the existing technical problems, the main objective of this invention is to provide an automatic water-blocking system and its operation method. This system can automatically open when backflow occurs in the toilets or emergency oil tanks of a hydropower plant, thereby preventing backflow and effectively preventing the spread of backflow that could cause plant unit failures, thus ensuring the safety of equipment operation.

[0004] To achieve the above-mentioned technical features, the present invention aims to provide an automatic water-blocking system, comprising an installation foundation, a drainage ditch on the installation foundation, a first stepped groove on one side of the top of the drainage ditch, a top cover structure hingedly installed at the location of the first stepped groove via a cover plate rotation opening mechanism, an inner cover structure slidably installed at the bottom end of the top cover structure via a sliding power device, and a self-weight flip-top baffle structure installed on the side of the inner cover structure; a second stepped groove on the other side of the top of the drainage ditch, with the non-hinged side of the top cover structure supported on the top of the second stepped groove.

[0005] The top cover structure includes a top cover body, on which drainage holes are evenly distributed.

[0006] The cover plate rotation opening mechanism includes a rotation motor, which is fixed on the mounting base. The output shaft of the rotation motor is connected to the side of the top cover body through a rotation rod, and drives the cover plate body to rotate and open.

[0007] The inner cover structure includes a symmetrically arranged inner cover body, on which drainage holes are uniformly arranged.

[0008] The sliding power device includes slide rails symmetrically fixed at the bottom of the top cover body, and the inner cover body is slidably mounted on the slide rails via a sliding sleeve. A hydraulic cylinder for pushing the inner cover body is provided between the inner cover body and the top cover body, and an oil pipe is connected to the hydraulic cylinder.

[0009] The end portion of the inner cover body is provided with an inner cover end sealing plate for sealing against the wall.

[0010] The top cover body is provided with a top cover side sealing plate on the side where the cover plate rotation opening mechanism is located.

[0011] The self-weight flip-top baffle structure includes a hinge installed on the side wall of the inner cover body, and a flip-top baffle is connected to the hinge.

[0012] It also includes a control system, which includes a water flow indicator installed on the top of the installation foundation and located on the side of the cover plate rotation opening mechanism. The water flow indicator is connected to the signal input terminal of the controller via a signal line. The signal output terminal of the controller is connected to an SMS alarm device, a WIFI alarm device, and an audible and visual warning device, respectively.

[0013] The SMS alarm device sends an alarm SMS to notify the relevant personnel; the WIFI alarm device sends the alarm information to the central control room to initiate emergency response; the audible and visual alarm device issues an audible and visual alarm.

[0014] The signal output terminal of the controller is connected to both the cover plate rotation opening mechanism and the sliding power device, and controls the rotation motor and the hydraulic cylinder respectively to realize the rotation opening of the top cover plate structure and the sliding opening of the inner cover plate structure.

[0015] An operation method for an automatic water-blocking system includes the following steps:

[0016] Step 1, System Installation:

[0017] Based on the installation location of the installation foundation, assemble and install the system's cover plate rotation opening mechanism, top cover plate structure, sliding power device, inner cover plate structure, and self-weight flip cover baffle structure into place;

[0018] Step 2, normal system operation:

[0019] During normal use, when the water flows to the location of the top cover structure, the water will automatically flow from the top cover drain hole into the drain ditch at its bottom, and then achieve automatic drainage through the drain ditch;

[0020] Step 3, emergency water blocking of the system:

[0021] In the event of severe rainstorms or other special circumstances where the water flow is too large and the drainage ditch cannot drain the water in time, the water will flow over the top cover structure and pass through the water flow indicator at the rear. The water flow indicator will automatically detect the water flow signal and transmit the signal to the controller. At this time, the controller will automatically activate the SMS alarm device to send an alarm SMS to notify the relevant personnel; the WIFI alarm device will send the alarm information to the central control room to initiate emergency rescue; and the audible and visual warning device will issue an audible and visual alarm.

[0022] At the same time, the controller controls the cover plate rotation opening mechanism, drives the rotating rod to rotate through the rotating motor, and then drives the top cover body to rotate and open through the rotating rod; then, the controller controls the sliding power device, drives the two inner cover bodies to slide towards the two side walls through the oil cylinder, until the sealing plate at the end of the inner cover is tightly attached to the two side walls and sealed, thus forming a horizontal water baffle structure together with the top cover body.

[0023] Furthermore, during the rotation and opening process of the top cover body, the flip baffle of the self-weight flip cover baffle structure will adhere to the surface of the inner cover body under its own weight, thereby sealing the drainage hole of the inner cover.

[0024] Step 4, System Reset:

[0025] Once the emergency is over, the control system automatically controls the sliding power device to retract and reset the inner cover structure. Then, the cover rotation and opening mechanism is controlled to rotate and close the top cover structure again. Furthermore, the self-weight flip-top baffle structure will adhere to the inner wall of the drainage ditch under its own weight. Finally, the system will return to normal operation.

[0026] The present invention has the following beneficial effects:

[0027] 1. This invention solves the problem of inability to promptly block backflow in areas such as factory restrooms and emergency oil tank operating rooms, protecting surrounding equipment from backflow. It boasts advantages such as rapid response and high emergency efficiency, improving the automation level of emergency response to backflow in factory buildings and effectively enhancing the reliability of safe and stable operation of power plant buildings.

[0028] 2. The cover plate rotation opening mechanism described above can be used to control the automatic rotation and opening of the top cover body to deal with water blocking operations in emergency situations.

[0029] 3. The inner cover plate structure described above is mainly used to compensate for the insufficient length of the top cover plate structure.

[0030] 4. The aforementioned sliding power device can be used to provide sliding power for the inner cover plate structure.

[0031] 5. The inner cover end sealing plate described above can effectively seal the end.

[0032] 6. The aforementioned top cover side sealing plate can be used to form an effective seal between the top cover body and the mounting base.

[0033] 7. The self-weight flip-top baffle structure described above can automatically seal the inner cover body to ensure water blocking effect.

[0034] 8. The above-mentioned control system can realize the automatic control of the entire system. Attached Figure Description

[0046] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0047] Example 1:

[0048] See Figure 1-4An automatic water-blocking system includes an installation foundation 8, on which a drainage ditch 7 is provided. A first stepped groove 801 is provided on one side of the top of the drainage ditch 7. A top cover structure 1 is hinged to the first stepped groove 801 via a cover plate rotation opening mechanism 4. An inner cover structure 5 is slidably installed at the bottom end of the top cover structure 1 via a sliding power device 3. A self-weight flip-top baffle structure 6 is installed on the side of the inner cover structure 5. A second stepped groove 802 is provided on the other side of the top of the drainage ditch 7, and the non-hinged side of the top cover structure 1 is supported on the top of the second stepped groove 802. By employing the above-mentioned automatic water-blocking system, when backflow occurs in the toilets or emergency oil tanks of a hydropower station plant, it can automatically open to prevent backflow, effectively preventing the spread of backflow and the resulting plant unit malfunctions, thus ensuring the safety of equipment operation. In specific operation, in case of an emergency, through...

[0049] Furthermore, the top cover structure 1 includes a top cover body 101, on which top cover drainage holes 102 are evenly distributed. The top cover structure 1 enables automatic drainage during normal operation. During normal operation, water will automatically flow from the top cover drainage holes 102 into the drainage ditch, thereby achieving the purpose of drainage.

[0050] Furthermore, the cover plate rotation opening mechanism 4 includes a rotation motor 401, which is fixed on the mounting base 8. The output shaft of the rotation motor 401 is connected to the side of the top cover body 101 via a rotation rod 402, and drives the cover plate body 101 to rotate and open. The cover plate rotation opening mechanism 4 described above can be used to control the automatic rotation and opening of the top cover body 101 to handle water blocking operations in emergency situations. When water blocking is required, the rotation motor 401 is activated, driving the rotation rod 402, which in turn drives the top cover body 101 to rotate and open.

[0051] Furthermore, the inner cover structure 5 includes symmetrically arranged inner cover bodies 501, with inner cover drainage holes 502 evenly distributed on the inner cover bodies 501. The inner cover structure 5 is primarily used to compensate for the insufficient length of the top cover structure 1. Since the top cover structure 1 is some distance from the walls on both sides, it cannot completely block water if it cannot achieve the desired water-blocking effect. Therefore, the inner cover structure 5 is provided to ensure that after the top cover structure 1 is opened, the inner cover structure 5 extends out and fits against the wall to achieve the end-water-blocking effect.

[0052] Furthermore, the sliding power device 3 includes a slide rail 301 symmetrically fixed to the bottom end of the top cover body 101. The inner cover body 501 is slidably mounted on the slide rail 301 via a sliding sleeve. A hydraulic cylinder 303 for pushing the inner cover body 501 is provided between the inner cover body 501 and the top cover body 101. An oil pipe 302 is connected to the hydraulic cylinder 303. The aforementioned sliding power device 3 can provide sliding power for the inner cover structure 5. When it is necessary to drive the inner cover structure 5 to extend, by activating the hydraulic cylinder 303, the hydraulic cylinder 303 will push the inner cover body 501 to slide out along the slide rail, thus blocking the gap between the top cover structure 1 and the wall, achieving the purpose of completely blocking water.

[0053] Furthermore, the end portion of the inner cover body 501 is provided with an inner cover end sealing plate 503 for sealing against the wall. The inner cover end sealing plate 503 effectively seals the end.

[0054] Furthermore, the top cover body 101 is provided with a top cover side sealing plate 103 on the side where the cover plate rotation opening mechanism 4 is located. The top cover side sealing plate 103 can be used to form an effective seal between the top cover body 101 and the mounting base.

[0055] Furthermore, the self-weight flip-top baffle structure 6 includes a hinge 601 installed on the side wall of the inner cover body 501, and a flip-top baffle 602 is connected to the hinge 601. The self-weight flip-top baffle structure 6 enables the inner cover body 501 to automatically seal, ensuring a water-blocking effect.

[0056] Furthermore, the system also includes a control system. This control system comprises a water flow indicator 2 mounted on top of the mounting base 8 and located on the side of the cover plate rotation opening mechanism 4. The water flow indicator 2 is connected to the signal input terminal of the controller via a signal line. The signal output terminal of the controller is connected to an SMS alarm device, a WIFI alarm device, and an audible and visual warning device, respectively. This control system enables automatic control of the entire system.

[0057] Furthermore, the SMS alarm device sends an alarm SMS to notify relevant personnel; the WIFI alarm device sends the alarm information to the central control room to initiate emergency response; and the audible and visual alarm device issues an audible and visual alarm. These control methods enhance the flexibility and versatility of the system.

[0058] Furthermore, the signal output terminal of the controller is simultaneously connected to the cover plate rotation opening mechanism 4 and the sliding power device 3, and controls the actions of the rotary motor 401 and the hydraulic cylinder 303 respectively to realize the rotation opening of the top cover plate structure 1 and the sliding opening of the inner cover plate structure 5. Through the above control method, the automatic control of the cover plate rotation opening mechanism 4 and the sliding power device 3 can be realized to improve control efficiency.

[0059] Example 2:

[0060] An operation method for an automatic water-blocking system includes the following steps:

[0061] Step 1, System Installation:

[0063] Step 2, normal system operation:

[0064] During normal use, when the water flows to the location of the top cover structure 1, the water will automatically flow from the top cover drain hole 102 into the drain ditch 7 at its bottom, and then achieve automatic drainage through the drain ditch 7.

[0065] Step 3, emergency water blocking of the system:

[0066] In the event of a severe rainstorm or other special circumstances where the water flow is too large and the drainage ditch cannot drain the water in time, the water will flow over the top cover structure 1 and pass through the water flow indicator 2 at the rear. The water flow indicator 2 will automatically detect the water flow signal and transmit the signal to the controller. At this time, the controller will automatically control the SMS alarm device to send an alarm SMS to notify the relevant personnel; the WIFI alarm device will send the alarm information to the central control room to initiate emergency rescue; and the audible and visual warning device will issue an audible and visual alarm.

[0067] At the same time, the controller controls the cover plate rotation opening mechanism 4, and the rotating motor 401 drives the rotating rod 402 to rotate, which in turn drives the top cover body 101 to rotate and open; then, the controller controls the sliding power device 3, which drives the two inner cover bodies 501 to slide towards the side walls through the oil cylinder 303, until the inner cover end sealing plate 503 is tightly attached to the side walls and sealed, thus forming a horizontal water baffle structure together with the top cover body 101;

[0068] Furthermore, during the rotation and opening process of the top cover body 101, the flip baffle 602 of the self-weight flip cover baffle structure 6 will adhere to the surface of the inner cover body 501 under its own weight, thereby sealing the inner cover drainage hole 502.

[0069] Step 4, System Reset:

[0070] After the emergency is resolved, the sliding power device 3 is automatically controlled by the control system to retract and reset the inner cover structure 5. Then, the cover rotation opening mechanism 4 is controlled to rotate and close the top cover structure 1 again. Moreover, the flip baffle 602 of the self-weight flip cover baffle structure 6 will adhere to the inner wall of the drainage ditch 7 under its own weight. Finally, the system will return to normal operation.
