Description

Technical Field

[0001] This utility model relates to the field of electric gate valve control technology, and in particular to an automatic water supply and drainage control device for an electric gate valve. Background Technology

[0002] In mining operations, surface overflow ponds and storage tanks are installed. Water from the mine is pumped to these storage tanks, and the difference in elevation between the surface and the mine allows water to be drawn underground for production use. Both the surface overflow pond and the storage tank have drainage pipes leading from underground. The storage tank is approximately 15-20 meters higher than the overflow pond and requires gate valves to ensure smooth water flow. The flow of water in the overflow pond and the storage tank is controlled by four separate electric gate valves.

[0003] In the original electric valve design, each electric gate valve corresponds to a forward and a reverse button. When the switch button SB is pressed, the AC contactor's self-locking coil is energized, the normally open contact of the AC contactor changes to a normally closed position, and the corresponding electric gate valve actuates. After the valve is fully closed, it triggers a limit switch, de-energizing the AC contactor coil and stopping the motor. This design requires manual operation to control the valve opening and closing via manual buttons. However, since the overflow tank and water tank are buried underground, the specific water level inside the tank cannot be clearly seen. Manual control is costly and inefficient, and the inability to monitor the water level in real time can easily lead to uncontrolled water levels or resource waste. Furthermore, the height difference between the water tank and the overflow tank results in uneven water pressure, making it difficult to coordinate the operation of multiple valves manually, thus affecting production efficiency. In view of this, this utility model proposes an automatic water supply and drainage control device for electric gate valves that can automatically and accurately coordinate the operation of multiple valves according to the water level. Utility Model Content

[0004] The purpose of this invention is to address the problems in the background technology, such as the need for manual control of electric gate valves, the inability to monitor water levels in real time leading to high costs, and the difficulty in coordinating the actions of multiple valves. This invention proposes an automatic water supply and drainage control device for electric gate valves.

[0005] The technical solution of this utility model is as follows: an electric gate valve automatic water supply and drainage control device, including a drainage pipeline for conveying well water to a water storage tank and an overflow pool, wherein the drainage pipeline is a No. 1 water pipe and a No. 2 water pipe, and the control device includes a No. 1 gate valve and a No. 2 gate valve connected in series with the No. 1 water pipe, and a No. 3 gate valve and a No. 4 gate valve connected in series with the No. 2 water pipe. The control device also includes two sets of float switches, four intermediate relays, multiple sets of contacts, and control circuits for the four sets of gate valves mentioned above. The two sets of float switches are float #1 and float #2, and the four intermediate relays are KA1, KA2, KA3 and KA4. Each float switch has one normally closed contact and one normally open contact for monitoring the water level in the storage tank. The normally open contact of float switch #1 is connected to the coil of intermediate relay KA1, and the normally closed contact of float switch #1 is connected to the coil of intermediate relay KA2, which is used to control gate valve #1 and gate valve #2 corresponding to water pipe #1. The normally open contact of float switch #2 is connected to the coil of intermediate relay KA3, and the normally closed contact of float switch #2 is connected to the coil of intermediate relay KA4 to control gate valves #3 and #4 corresponding to water pipe #2.

[0006] Optionally, the intermediate relay is a 220V intermediate relay.

[0007] Optionally, the normally open contact of the intermediate relay KA1 is connected in series with the normally closed contacts of KA1-1 and KA2-2 respectively, and in parallel with the valve opening button SB1-1 of the #1 gate valve motor and the valve closing button SB2-2 of the #2 gate valve motor, for automatic control of opening the #1 gate valve and closing the #2 gate valve, so that the water in the #1 water pipe enters the water storage tank. The normally closed contact of intermediate relay KA2 is connected in series with the normally closed contacts of KA1-2 and KA2-1, and in parallel with the valve opening button SB2-1 of the #2 gate valve motor and the valve closing button SB1-2 of the #1 gate valve motor. This is used to automatically control the opening of the #2 gate valve and the closing of the #1 gate valve, so that the water in the #1 water pipe enters the overflow pool.

[0008] Optionally, the normally open contact of intermediate relay KA3 is connected in series with the normally closed contacts of KA3-1 and KA4-2 respectively, and then connected in parallel with the valve opening button SB3-1 of gate valve motor #3 and the valve closing button SB4-2 of gate valve motor #4, for automatic control of opening gate valve #3 and closing gate valve #4, so that water in water pipe #2 enters the water storage tank. The normally closed contact of intermediate relay KA4 is connected in series with the normally closed contacts of KA3-2 and KA4-1, and then connected in parallel with the valve opening button SB4-1 of the #4 gate valve motor and the valve closing button SB3-2 of the #3 gate valve motor. This is used to automatically control the opening of the #4 gate valve and the closing of the #3 gate valve, so that the water in the #2 water pipe can enter the overflow pool.

[0009] Optionally, a normally open contact is connected in parallel on the manual gate valve switch SB, and the normally open contact is an intermediate relay contact.

[0010] Optionally, the float switch controls the energization and de-energization of the intermediate relay coil based on the water level change in the water tank. The intermediate relay controls the forward and reverse rotation of the electric valve motor by controlling the AC contactor coil and contacts, thereby completing the opening and closing of the valve.

[0011] In summary, this application includes at least one of the following beneficial technical effects: This utility model improves the circuit by adding a float and an intermediate relay, thereby enabling automatic opening and closing of the valve, saving labor, reducing costs, and improving control accuracy. By changing the height difference between float #1 and float #2, gate valves #1 and #3, and gate valves #2 and #4 are made asynchronous, thus avoiding the situation where water can flow through water pipes #1 and #2 but cannot enter the water tank. Further improvements enable the float switch and relay to work together to achieve precise water level control, and parallel contacts ensure that automatic / manual modes do not interfere with each other, reducing labor costs and improving water resource utilization. The material is readily available, and the float switch is automatically controlled with real-time water level feedback, saving labor costs. It is highly practical and solves practical problems in on-site production. In summary, this utility model monitors the water level in real time through a float switch and automatically controls the forward and reverse rotation of the electric gate valve with an intermediate relay. It eliminates the need for manual operation, reduces control costs, improves efficiency, and can accurately coordinate the actions of multiple valves. At the same time, it prevents water level loss and resource waste, ensures a stable water supply to the storage tank, and meets the water demand for mining production. Attached Figure Description

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0015] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0017] like Figures 1 to 4 As shown, the present invention proposes an electric gate valve automatic water supply and drainage control device, which includes a drainage pipeline for supplying water from well water 1 to water storage tank 2 and overflow pool 3. The drainage pipelines are respectively 1# water pipe 4 and 2# water pipe 5. The control device includes 1# gate valve 6 and 2# gate valve 7 connected in series with 1# water pipe 4, and 3# gate valve 8 and 4# gate valve 9 connected in series with 2# water pipe 5. The control device also includes two sets of float switches, four intermediate relays, multiple sets of contacts, and the control circuits for the four sets of gate valves mentioned above; The two sets of float switches are float #1 and float #2, and the four intermediate relays are KA1, KA2, KA3 and KA4; the intermediate relays are 220V intermediate relays. Each float switch has one normally closed contact and one normally open contact for monitoring the water level in storage tank 2; The normally open contact of float switch #1 is connected to the coil of intermediate relay KA1, and the normally closed contact of float switch #1 is connected to the coil of intermediate relay KA2. This is used to control gate valve #1 6 and gate valve #2 7 corresponding to water pipe #1 4. The normally open contact of intermediate relay KA1 is connected in series with the normally closed contacts of KA1-1 and KA2-2 respectively, and in parallel with the valve opening button SB1-1 of the motor of gate valve #1 6 and the valve closing button SB2-2 of the motor of gate valve #2 7. This is used to automatically control the opening of gate valve #1 6 and the closing of gate valve #2 7, so that water in water pipe #1 4 enters water storage tank 2. The normally closed contact of intermediate relay KA2 is connected in series with the normally closed contacts of KA1-2 and KA2-1, and in parallel with the valve opening button SB2-1 of the motor of gate valve 7 and the valve closing button SB1-2 of the motor of gate valve 6, respectively, to automatically control the opening of gate valve 7 and the closing of gate valve 6, so that the water in water pipe 4 of 1 enters the overflow pool 3.

[0018] Specifically, taking the newly added intermediate relays KA1 and KA2 in water pipe 4 as an example: when the water level in overflow tank 3 is high, the normally open contact of the float switch controlling KA1 becomes normally closed, and the normally closed contact of the float switch controlling KA2 becomes normally open. The coil of intermediate relay KA1 is energized, and the coil of KA1 controls the forward rotation of the motor of gate valve 6 and the reverse rotation of the motor of gate valve 7. Therefore, gate valve 6 of 1 opens, gate valve 7 of 2 closes, and water in water pipe 4 enters through gate valve 6 of 1. The water enters the storage tank 2 but cannot enter the overflow pool 3. When the water level in the overflow pool 3 is low, the normally open contact of the float switch controlling KA2 becomes normally closed, and the normally closed contact of the float switch controlling KA1 becomes normally open. The intermediate relay coil of KA2 is energized, and the coil of KA2 controls the forward rotation of the motor of gate valve 7 and the reverse rotation of the motor of gate valve 6. Therefore, gate valve 6 is closed, gate valve 7 is opened, and the water in pipe 4 enters the overflow pool 3 through gate valve 6, but cannot enter the storage tank 2.

[0019] The normally open contact of float switch #2 is connected to the coil of intermediate relay KA3, and the normally closed contact of float switch #2 is connected to the coil of intermediate relay KA4 to control gate valves #3 (8) and #4 (9) corresponding to water pipe #2. The normally open contact of intermediate relay KA3 is connected in series with the normally closed contacts of KA3-1 and KA4-2, respectively, and then connected in parallel with the valve opening button SB3-1 of the motor of gate valve #3 (8) and the valve closing button SB4-2 of the motor of gate valve #4 (9), to automatically control the opening of gate valve #3 (8) and the closing of gate valve #4 (9), so that water in water pipe #2 (5) enters water storage tank 2. The normally closed contact of intermediate relay KA4 is connected in series with the normally closed contacts of KA3-2 and KA4-1, and then connected in parallel with the valve opening button SB4-1 of the motor of gate valve 9 and the valve closing button SB3-2 of the motor of gate valve 8, respectively. This is used to automatically control the opening of gate valve 9 and the closing of gate valve 8, so that the water in water pipe 5 of 2 can enter the overflow pool 3.

[0020] Specifically, taking the newly added intermediate relays KA3 and KA4 in water pipe 5 as an example: when the water level in storage tank 2 is high, the normally open contact of the float switch controlling KA3 becomes normally closed, and the normally closed contact of the float switch controlling KA4 becomes normally open; the coil of intermediate relay KA3 is energized, and the coil of KA3 controls the forward rotation of the motor of gate valve 8 and the reverse rotation of the motor of gate valve 9, so gate valve 8 opens and gate valve 9 closes, and the water in water pipe 5 enters through gate valve 8. Water enters storage tank 2 but cannot flow into overflow tank 3. When the water level in overflow tank 3 is low, the normally open contact of the float switch controlling KA4 changes to a normally closed contact, and the normally closed contact of the float switch controlling KA3 changes to a normally open contact. The coil of the intermediate relay in KA4 is energized, which controls the forward rotation of the motor of gate valve 9 (#4) and the reverse rotation of the motor of gate valve 8 (#3). Therefore, gate valve 8 (#3) closes, gate valve 9 (#4) opens, and water from pipe 5 (#2) enters overflow tank 3 through gate valve 6 (#1), but cannot enter storage tank 2. Through technical improvements, it can be ensured that both tanks can be fully filled with water.

[0021] In this embodiment, a normally open contact and a normally closed contact are connected in parallel on the manual switch SB of the gate valve. The normally open contact is an intermediate relay contact, and the normally closed contact is the normally closed contact of the corresponding intermediate relay. Furthermore, the float switch controls the energization and de-energization of the intermediate relay coil based on the water level changes in the overflow tank 3 and the storage tank 2. The intermediate relay controls the forward and reverse rotation of the electric valve motor by controlling the AC contactor coil and contacts, thereby completing the opening and closing of the valve.

[0022] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
