AI Technical Summary
Existing earth and rock dams are difficult to detect and discharge in time when seeping water, resulting in an increase in the risk of dam collapse. Especially when the seepage volume is insufficient to penetrate downstream, inspectors cannot detect it in time, especially in locations with a narrow width of the earth and rock dam, which increases the risk of earth loss.
A water seepage collection and discharge device for earth and rock dams is designed, including a water accumulation sensor, a collection mechanism, a control circuit and a solenoid valve. The water accumulation sensor is used to detect the water volume and automatically open the solenoid valve to discharge the water flow when it reaches a certain depth. Combined with the high-pressure flushing function, it ensures the stable and reliable operation of the equipment.
It effectively reduces the risk of earth loss and dam collapse caused by excessive water accumulation, ensures the safety of the earth and rock dam and the stability of equipment, and prevents blockage through automatic drainage and regular high-pressure flushing.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earth-rock dam drainage equipment, in particular to an earth-rock dam seepage water collection and discharge device. Background Art
[0002] In existing earth-rock dam safety management, professional inspection personnel are typically assigned to conduct safety inspections of earth-rock dams, either regularly or irregularly, to identify and address problems as early as possible, thereby preventing serious secondary disasters caused by dam failure. This inspection method is inconvenient for inspection personnel due to the high height and large size of earth-rock dams and the large number of inspection points. More importantly, when water seepage occurs internally in an earth-rock dam—that is, when the water on the upstream side of the dam is insufficient to penetrate the downstream side—inspectors are unable to detect the problem. Consequently, over time, as water seeps into the dam and the upper and lower dam bodies become connected, earth loss in the corresponding locations (especially in areas where the width of the dam is relatively narrow) increases the risk of dam failure. Utility Model Content
[0003] In order to overcome the disadvantage that the existing earth-rock dams do not have a device that can discharge internal seepage in time, which correspondingly increases the risk of dam collapse, the utility model provides an earth-rock dam seepage water collection and discharge device that is mainly used in areas where earth-rock dams are prone to water seepage (such as the relatively narrowest part of the earth-rock dam, etc.), which can uniformly collect water that seeps into the earth-rock dam from the water side upstream of the earth-rock dam, and automatically open the valve to discharge it when the water volume reaches a certain level, reducing the risk of dam collapse due to earth loss caused by excessive water accumulation. In addition, the staff can also perform high-pressure flushing on the sediment in the collection mechanism as needed, so that the entire equipment can work stably and reliably.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A device for collecting and discharging seepage water from an earth-rock dam includes a water accumulation sensor and is characterized in that it also has a collecting mechanism and a control circuit; the collecting mechanism includes a water accumulation bin, a flushing pipe, a drain pipe, a valve, a solenoid valve, and a water collecting cover, the water collecting cover is a conical structure, the surface of the water collecting cover is distributed with water-permeable holes, and the lower end of the water collecting cover and the upper end of the water accumulation bin are installed together; a filter cloth is installed on the surface of the water collecting cover, the lower end of the flushing pipe is installed on the upper end of the water collecting cover, and one side of the drain pipe is installed on the outside of the water accumulation bin; the upper end of the flushing pipe is a closed structure and a connecting pipe is installed on the side, one side of the connecting pipe is connected to one end of the valve, and the other end of the valve is installed with a branch pipe, the side end of the drain pipe is connected to one end of the solenoid valve, and the other end of the solenoid valve is installed with a drain pipe; the water accumulation sensor is installed in the water accumulation bin; the control circuit is installed in the component box, and the collecting mechanism is installed inside the earth-rock dam, the signal output end of the water accumulation sensor is electrically connected to the signal input end of the control circuit, and the power output end of the control circuit is electrically connected to the power input end of the solenoid valve.
[0006] Furthermore, the solenoid valve is a normally closed valve core solenoid valve, and a power switch is connected in series between the positive power input end of the solenoid valve and the positive power output end of the power module.
[0007] Furthermore, the valve is located outside the upper end of the earth-rock dam body, and the solenoid valve and the drain pipe are located at the outer end on the downstream backwater side of the earth-rock dam.
[0008] Furthermore, the control circuit includes an electrically connected resistor, a transistor, and a relay, the positive power input end of the relay is connected to the control power input end, one end of the resistor is connected to the base of the transistor, and the collector of the transistor is connected to the negative power input end of the relay.
[0009] Furthermore, the lower end and side ends of the water storage bin are closed structures.
[0010] Compared with the existing technology, the present invention has the following beneficial effects: (1) multiple sets of the present invention are used in coordination and are mainly installed in areas where leakage is prone to occur in earth-rock dams (such as the narrowest part of the earth-rock dam relative width). When water upstream of the earth-rock dam seeps into the vicinity of the water collection cover, it can be filtered by the geotextile (to prevent mud and other substances from entering the water collection cover) and then enter the water collection bin for collection. When the water volume reaches a certain depth and submerges the detection head of the water collection sensor, the water collection sensor will output a voltage signal to the control circuit, and then the solenoid valve will open to discharge the accumulated water, reducing the risk of earth loss and dam collapse due to excessive water accumulation; (2) After a certain period of time, the staff can also carry out high-pressure flushing of the sediment in the collection mechanism and the water collection bin and the water collection cover by using a high-pressure pump to pump water as needed, so that the entire equipment can work stably and reliably.

[0014] Figure 1 、 2 As shown in, the earth-rock dam seepage collection and discharge device includes a power module W1, a water accumulation sensor W2, and also has a collection mechanism and a control circuit 1; the collection mechanism includes a water accumulation bin 21, a flushing pipe 22, a drain pipe 23, a manual valve 24, an electromagnetic valve DC, and a water collection cover 25. The water collection cover 25 is a conical structure from bottom to top, and a plurality of water-permeable holes 251 are distributed on the surface of the water collection cover 25 at a certain distance. The outer side of the lower end of the water collection cover 25 and the outer side of the upper end of the water accumulation bin 21 are sealed and welded together; the surface of the water collection cover 25 (completely wrapped) is installed with a geotextile 26 as a filter material, and there is an opening in the middle of the upper end of the water collection cover 25 and the middle of the right side of the lower end of the water accumulation bin respectively. The lower end of the flushing pipe 22 is sealed and vertically welded to the outer side of the upper end opening of the water collection cover 25, and the left side of the drain pipe 23 is sealed and welded to the outer side of the right end opening of the water collection cover 25; the upper end of the flushing pipe 22 is a closed structure and the right end is welded A connecting pipe is connected to the interior of the water storage tank 21, and the right side of the connecting pipe is connected to one end of the manual valve 24 via a threaded connection. A branch pipe 27 is installed on the other end of the manual valve 24 via a threaded connection. The right end of the drain pipe 23 is connected to one end of the electromagnetic valve DC via a threaded connection, and a drain pipe 28 is installed on the other end of the electromagnetic valve DC via a threaded connection. The water accumulation sensor is installed in the middle of the front inner end of the water storage tank 21 (with the detection head downward), and the wire connected to the water accumulation sensor W2 is sealed in a hose. The hose 4 is led out through the drain pipe to the right end opening of the drain pipe 28 (the opening is sealed with sealant). The power module W1 and the control circuit 1 are installed in the component box 5. Multiple sets of the new collection mechanisms are pre-buried and installed at intervals in the middle of the front and rear ends of the lower part of the earth-rock dam (generally installed in a position where the width of the earth-rock dam is narrower. Specifically, the collection mechanism is installed in the middle of the front and rear ends of the lower part of the earth-rock dam during construction).
[0015] Figure 1 、 2As shown in the figure, the solenoid valve DC is a normally closed valve core solenoid valve. A power switch S1 is connected in series between the positive power input terminal of the solenoid valve DC and the positive power output terminal of the power module W1. The power switch handle is located outside the front opening of the component box. The manual valve 24 is located outside the upper end of the earth-rock dam body. The solenoid valve DC and the drain pipe 28 are located at the rear outer end on the downstream side of the earth-rock dam. The component box 5 is installed at a high point on the downstream side (for example, a support frame is provided, and the waterproof component box is installed at a high point on the support frame). The control circuit includes a resistor R1, a transistor T1, and a relay J1 connected via circuit board wiring. The positive power input terminal of relay J1 is connected to the control power input terminal. One end of resistor R1 is connected to the base of transistor T1, and the collector of transistor T1 is connected to the negative power input terminal of relay J1. The lower end and side ends of the water storage tank 21 are closed structures. Connect power input pins 1 and 2 of power module W1 to the two poles of the AC 220V power supply via wires. Connect power output pins 3 and 4 of power module W1 to power input pins 1 and 2 of water sensor W2, the positive power input of relay J1, the power input of the control circuit, and the emitter of transistor Q1 via wires. Connect signal output pin 3 of water sensor W2 to the other end of resistor R1, the signal input of the control circuit, via wires. Connect the normally open contact of relay J1 and pin 4 of power module W1 to the DC power input of the solenoid valve via wires.
[0016] Figure 1 、 2As shown in the figure, multiple sets of this novel device are used in conjunction with each other, primarily installed in areas prone to leakage in earth-rock dams (such as the narrowest part of the dam). Multiple sets of this novel collection mechanism are pre-installed at intervals between left and right (multiple sets can also be installed at intervals between front and back) in the middle of the lower front and rear ends of the dam. (This is typically installed in the narrowest part of the dam. Specifically, during construction, the collection mechanism is installed in the middle of the lower front and rear ends of the dam.) When power is supplied to power module W1, power output pins 3 and 4 output a stable 12V DC power supply to the control circuit and the power input of the water accumulation sensor. Normally, water from the upstream side of the dam seeps through the earth and rocks. When this water seeps into the vicinity of the water accumulation cover 25, it is filtered through the geotextile 26 (preventing soil and other materials from entering the water accumulation chamber) and then collected in the water accumulation chamber 21. (The water accumulation chamber has permeable holes 251 on its surface, allowing the filtered water to enter the water accumulation chamber 21.) When the amount of water entering the water storage tank 21 is low and does not submerge the detection head of the water sensor W2, pin 3 of the water sensor W2 does not output a high level, the solenoid valve DC is not energized, and the valve core does not open. When the amount of water entering the water storage tank 21 is large and submerges the detection head of the water sensor W2, pin 3 of the water sensor W2 outputs a high level. This high level is reduced and limited by resistor R1 and enters the base of transistor T1. Transistor T1 conducts and the collector outputs a low level, which enters the negative power input terminal of relay J1. Relay J1 is energized, closing the control power input terminal and the normally open contact terminal. This energizes the solenoid valve DC and opens the valve core. The water in the water storage tank 21 is discharged through the drain pipe and the drain pipe 28 to the downstream of the dam. When the water in the water storage tank 21 is discharged and no longer submerges the detection head of the water sensor W2, pin 3 of the water sensor W2 does not output a high level. Relay J1 is de-energized and no longer energized, and the solenoid valve DC closes, preventing external dust and other particles from entering the drain pipe. After the present application has been used for a period of time, the power switch S1 can be turned on. The power switch S1 short-circuits the positive power input terminal of the solenoid valve DC and pin 3 of the power module W1. In this way, the solenoid valve DC will be energized and the valve core will be opened. Then the staff will seal the outlet pipe of the high-pressure water pump and the branch pipe 27 through a hose. The water inlet pipe of the high-pressure water pump is located below the water surface upstream of the earth-rock dam. After turning on the power switch of the high-pressure water pump (and opening the valve 24), the high-pressure water pump will be energized to output pressurized water into the flushing pipe 22. The high-pressure water will perform high-pressure flushing on the water storage tank and the inside of the water storage cover. The mud and the like that have settled or adhered to the water storage tank will be flushed and discharged downstream from the drain pipe. After the water becomes clear, the power switch S1 and the valve 24 will be turned off to complete the cleaning operation, so that the entire equipment can work stably and reliably (to prevent the drainage pipe from being blocked and unable to drain the seepage water, and at the same time, it can also facilitate a certain flushing effect on the inner surface of the geotextile to maintain good filtration performance (after flushing, turn off the power switch S1, valve 24 and the power switch of the high-pressure water pump, and remove the hose connected to the branch pipe). Figure 2Among them, the power module W1 is a finished product of an AC 220V to DC 12V switching power supply module; the resistance value of resistor R1 is 1K; the model of transistor T1 is 9013 (NPN type); the model of relay J1 is DC12V; the solenoid valve DC is a normally closed valve core solenoid valve with a power of 5W; the water accumulation sensor W2 is a finished water accumulation sensor model HSM-WT202, which has two power input terminals and one signal output terminal. When the detection head detects water, the signal output terminal outputs power, otherwise it does not output. Figure 2 The components used in the present invention are all existing mature industrial products, and this application does not elaborate on their working principles.
