Description

[Technical Field]

[0001] This invention relates to a gate device that can remotely monitor and control the status of gates in sewerage facilities and fully automatically control operation based on the water level in the waterway. [Background technology]

[0002] Sewage and rainwater discharged from homes, factories, etc. are collectively called "sewerage," and there are two types of sewage disposal methods: combined and separate. Combined systems remove sewage and rainwater in the same pipes, while separate systems remove sewage and rainwater in separate pipes. With combined systems, it is necessary to discharge sewage during heavy rain. For this reason, in emergencies due to heavy rain, workers manually operate gates on-site to ensure a drainage route for rainwater. In recent years, with the increasing frequency of heavy rain, there have been more cases of workers manually operating gates on-site, and operating gates located inside manholes under roads is dangerous, especially at night or during heavy rain, and it is also difficult to respond immediately to water levels in the drainage channel.

[0003] Meanwhile, remote monitoring and control technology has traditionally been used in systems that undergo frequent state changes and require control, such as substations and factory equipment. However, its application to systems that do not normally change and require control only on a one-off basis, such as sewerage facilities, has been slow. In recent years, advances in communication technology and PLCs (Programmable Logic Controllers) have made it less cost-prohibitive to apply remote monitoring and control technology in such fields.

[0004] As an example of these remote monitoring and control technologies, Patent Document 1 discloses a system for remotely monitoring and controlling sewerage facilities using a mobile communication network and mobile devices, allowing managers to instantly identify abnormalities and operate controls from mobile devices without having to be present at the site. Patent Document 2 discloses a system for remotely monitoring and controlling water supply and sewerage systems and industrial facilities via public lines, reliably transmitting control results even when communication is interrupted or the supervisor is absent. A reporting device notifies the supervisor by telephone or email, allowing the supervisor to immediately perform control operations from a mobile device. Patent Document 3 discloses a technology for introducing a "remote control device to be retrofitted" into the control panels of water supply and sewerage systems, floodgates, factories, power plants, etc., enabling remote operation without major modifications to existing systems. By physically pressing buttons and switches, the system reduces costs and construction time while ensuring safety during disasters and ensuring the effectiveness of remote control.

[0006] However, these remote monitoring and control technologies only suggest that they can be applied to sewerage facilities and have not been implemented in actual sewerage facilities. This invention actually remotely monitors and controls the gate devices of existing sewerage facilities, enabling immediate response to gate opening and closing and preventing danger to workers. [Means for solving the problem]

[0007] This is a gate device for remote monitoring and control of sewerage facilities that is connected to a central remote monitoring and control device via a communication line. The gate device includes a control panel, a water stop plate that can be attached to an existing slide guide, and an electric gate valve. The water stop plate and the electric gate valve are connected with a roughly truncated cone gate valve connector, and can be monitored and controlled on-site using the control panel, and can also be monitored and controlled from a distance using the central remote monitoring and control device via a communication line.

[0008] The gate device further includes a water level sensor, and can also be automatically controlled based on the water level in the waterway.

[0009] In addition to the central remote monitoring and control device, remote monitoring and control can also be performed from a portable terminal device. [Effects of the Invention]

[0010] As described above, this device allows constant monitoring of the gate and waterway water level, and gate opening and closing operations can be performed remotely and immediately, preventing danger to workers and reducing their workload. By reusing the existing slide guide and installing gate valve connection hardware, civil engineering work is not required, significantly shortening construction time and reducing construction costs. In addition, the gate valve can be attached, detached, and raised and lowered, making inspection and maintenance easy. [Brief explanation of the drawings]

[Figure 2] 1 is a block diagram of a gate device 100 for remote monitoring and control of sewerage facilities according to the present invention. [Figure 3] 1 is a front view of a controlled device 110 according to the present invention. [Figure 4] 2 is a side view of the controlled device 110 of the present invention as seen from the direction AA'. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0013] As shown in Figure 1, the sewerage facility remote monitoring and control gate device 100 of this invention is configured to be connected to a central remote monitoring and control device 300 via a communication line 200. The central remote monitoring and control device 300 can be configured as a monitoring and control panel, a personal computer, a tablet, a mobile phone (smartphone), etc. as long as it is capable of input and output. The communication line 200 can be any of a dedicated line, an internet line, a mobile phone communication network, etc.

[0014] The sewerage facility remote monitoring and control gate device 100 is composed of a control target device 110 that actually controls the raising and lowering of a water stop plate 112 to open and close the water gate, and a control panel 120 for controlling the control target device 110. The control panel 120 includes a communication control device, and sends the status of the control target device 110 to a central remote monitoring and control device 300 via a communication line 200, receives control information from the central remote monitoring and control device 300, and issues operation commands to the control target device 110 to control it. [Example]

[0015] The following describes an embodiment of the sewerage facility remote monitoring and control gate device 100 of the present invention. Figure 2 is an overall configuration diagram of the sewerage facility remote monitoring and control gate device 100, in which a control panel 120 and a controlled device 110 are connected by power cables and signal cables.

[0016] 3 is a front view of the controlled device 110, and FIG. 4 is a side view seen from the direction AA′. The controlled device 110 is composed of an electric gate valve 111, a water stop plate 112, a slide guide 113, and a gate valve connector 114.

[0017] The electric gate valve 111 uses an electric actuator (motor + reducer) to rotate the stem and raise and lower the water stop plate 112. This causes the water stop plate 112 to slide up and down in a groove along slide guides 113 on both sides, opening and closing the drainage channel. A three-phase induction motor, stepping motor, DC motor, etc. can be used as the motor.

[0018] A gate valve connector 114 of an approximately truncated cone is provided between the water stop plate 112 and the electric gate valve 111 to connect the water stop plate 112 and the electric gate valve 111, and the water stop plate 112 is drilled and threaded to integrate the water stop plate 112 and the electric gate valve 111 with the gate valve connector 114. This allows the existing slide guide 113 to be used, eliminates the need for large-scale civil engineering work, and enables significant cost reductions.

[0019] The control panel 120 has a communication control device that communicates with the central monitoring and control device 300, which allows the central monitoring and control device 300 to remotely open and close the waterstop 112 while monitoring the water level and the state of the control target equipment 110. The control panel 120 also displays the state of the control target equipment 110 and has an input device for operating the control target equipment 110. Therefore, even if an on-site equipment inspection or a failure occurs in the communication control device or communication line 200, etc., an operator can easily open and close the waterstop 112.

[0020] The water stop plate 112 is provided with a seal around its periphery to ensure watertightness, and the electric actuator is equipped with a torque limiting mechanism or limit switch for overload detection to ensure safety. Furthermore, even if the power supply is lost, the water stop plate 112 can be opened and closed manually using a handle attached to the electric gate valve 111.

[0021] In addition, a water level sensor 115 is installed, which detects the water level and automatically controls the electric gate valve 111 using a PLC built into the control panel 120, without the need for an operator, to open and close the water stop plate 112, making it possible to automatically control the water level. [Industrial Applicability]

[0022] There are many sewerage facilities throughout the country, and each facility has a number of gates scattered throughout. During heavy rain, workers must go to the site to operate these gates urgently. Therefore, by applying this device, it is possible to secure workers, ensure safety, reduce the workload, and enable constant monitoring of the sewerage system and immediate response to opening and closing operations of the gates, which is expected to contribute greatly to the development of industry.
