A gate control system for a drain pipe according to the present application will be described in detail with reference to the accompanying drawings.
Fig. 1 to 3 are schematic views showing a shutter control system for a drain pipe according to an embodiment of the present application. As shown in fig. 1 to 3, the present application provides a floodgate control system for a drain pipe, comprising a drain pipe 1, a floodgate 3, a power mechanism and a controller. Wherein the drain pipe 1 penetrates from one side of the inspection well 2, and the penetrating end of the drain pipe 1 on the inspection well 2 is disconnected, so that the inspection well 2 and the drain pipe 1 can be in through connection. The power mechanism is fixedly connected with the gate 3 and is used for driving the gate 3 to open and close, namely driving the gate 3 to reciprocate along the vertical direction so as to block the drain pipe 1 or open the drain pipe 1. When the power mechanism driving gate 3 is positioned at the through position of the drain pipe 1 and the inspection well 2, the drain pipe 1 is closed; when the power mechanism drives the gate 3 to be far away from the through position, the drain pipe 1 is opened to drain water. The controller may receive a remote control signal connected to the power mechanism for sending a command to the power mechanism to cause the power mechanism to perform the action of opening or closing the shutter 3. The gate control system for the drain pipe can realize the remote control of opening and closing of the gate 3, effectively reduces the difficulty of manually operating the gate by operation and maintenance personnel when the drain pipe 1 is in the field and avoids potential safety hazards.
In some embodiments, the aforementioned power mechanism may be a linear reciprocating mechanism, which may include, for example, a hoist 5 mounted on an upper portion of a ceiling of the manhole 2. The screw rod 4 in the hoist 5 is connected with the gate 3, so that the screw rod 4 is positioned in the inspection well 2 and extends downwards along the vertical direction, and the central axis of the screw rod 4 is parallel to the central axis of the inspection well 2. The lower extreme of lead screw 4 is provided with the hanging lug hole with the junction of gate 3, and the upper portion of gate 3 corresponds to be provided with the couple, can assemble gate 3 on lead screw 4 through the mode of hook. In the path of the up-and-down reciprocating motion of the gate 3, a guide ring can be arranged at the corresponding position of the inner wall of the inspection well 2, and the screw rod 4 drives the gate 3 to move up and down through the guide ring, so that the shaking of the screw rod 4 in the up-and-down moving process of the gate 3 can be effectively avoided. When the water draining device is specifically used, the motor of the headstock gear 5 drives the screw rod 4 to ascend so as to further enable the gate 3 to ascend to a set height, and the two ends of the water draining pipe 1 are communicated for draining. After the water is drained, the hoist 5 drives the screw rod 4 to descend, so that the gate 3 descends until the through position of the drain pipe 3 and the inspection well 2 is closed, and the gate 3 is closed. The power mechanism described above is exemplary only and not limiting. For example, the power mechanism may be a slider mechanism, a rocker mechanism, or the like.
In some embodiments, the gate 3 of the present application may comprise only the gate 3 body, and may also be a gate system including a limiting mechanism for limiting the gate 3 body. In a specific embodiment, the bottom of the drain pipe 1 may be configured to form a certain gap with the bottom of the manhole 2, or the bottom of the drain pipe 1 may be fitted to the bottom of the manhole 2. Two sliding grooves can be arranged on the inner wall of the inspection well 2, and the plane where the two sliding grooves are positioned is vertical to the extending direction of the drain pipe 1. Two sides of the gate 3 body can be arranged in the two sliding grooves, and under the drive of the hoist 5, the screw rod 4 drives the gate 3 body to slide up and down along the two sliding grooves. When the gate 3 body descends to the set position, the gate 3 body is attached to the section of the drain pipe 1 at the through position, and the blocking work of the drain pipe 1 is completed. The setting position can be set by referring to the descending distance of the screw rod 4 when the bottom of the gate 3 body is contacted with the bottom of the inspection well 2; the descending distance of the screw rod 4 after the drain pipe 1 is completely blocked by the gate 3 body can also be set. Further, in order to increase the tightness of the section fit between the gate 3 body and the drain pipe 1 at the through position, the end of the drain pipe 1 may be sleeved with a rubber gasket, and a sealing groove is provided corresponding to the gate 3 body and the rubber gasket. When the gate is moved to a closed state, the sealing groove is combined with the rubber gasket to increase sealability. It will be appreciated that the rubber pad fitted over the end of the drain pipe 1 is preferably soft rubber.
In another specific embodiment, the chute described above may be replaced with a U-shaped mount that includes a vertical portion extending along the side wall of the manhole 2 and a middle horizontal portion extending along the bottom of the manhole 2. The vertical portion may be provided as a chute to define the position of the body of the shutter 3 in the vertical and horizontal directions, and the intermediate horizontal portion may be provided as a groove to increase the structural stability of the body of the shutter 3 in the closed state. Because the drain pipe 1 has certain intensity and thickness, can set up the drain pipe 1 and have the extension of certain distance in inspection shaft 2, cut out a groove along the direction of perpendicular drain pipe 1 pipe wall, the bottom of this drain pipe 1 is the bottom of recess promptly, has arranged the rubber circle in the circumference of this recess. Correspondingly, the bottom of the gate 3 body needs to be set to be matched with the inner wall of the drain pipe 1, for example, the bottom of the gate 3 body can be in an arc shape matched with the bottom of the drain pipe 1, so that when the gate 3 body is positioned in the U-shaped groove, a preset sealing and blocking effect on the drain pipe 1 can be achieved.
In some embodiments, the gate control system for a drain pipe of the present application may further comprise an energy storage device coupled to the power mechanism for powering the power mechanism. In a specific embodiment, the energy storage device of the present application may be a lead acid battery or a lithium ion battery or the like. Based on the inconvenience of field power supply and the consideration of clean energy, the energy storage device may further include a solar photovoltaic panel 7, which can convert solar energy into electric energy and store the electric energy in a storage battery, so as to supply power to a power mechanism such as the hoist 5 in real time.
In some embodiments, a hollow supporting frame with a certain height can be arranged above the inspection well 2, and a steel platform 6 is paved on the supporting frame. A certain space is formed between the steel platform 6 and the top plate of the inspection well 2, and can be used for placing the hoist 5. In order to facilitate maintenance, a certain margin is required to be left in the space after the hoist 5 is placed. In other embodiments, as shown in fig. 1 to 3, in order to facilitate the maintenance and repair of the hoist 5 by the operation and maintenance personnel, the hoist 5 may be arranged in parallel with the support frame, that is, the hoist 5 is disposed outside the steel platform 6. An energy storage device 8 such as a storage battery can be placed on the steel platform 6, and a solar photovoltaic panel 7 can be placed on the upper portion of the energy storage device 8. The arrangement mode can reduce the occupied space of the control system on one hand, so that the mechanism is more compact; on the other hand, the solar photovoltaic panel 7 is ensured to be in an unshielded space, and is favorable for converting light energy into electric energy.
In some embodiments, a grid plate is further arranged at the upper part of the inspection well 2, and a falling prevention net is arranged below the grid plate. The grid plate and the top plate can be rotatably connected by adopting pin joint, hinge joint and the like, so that the grid plate can rotate around the joint between the grid plate and the top plate, and maintenance personnel can conveniently enter the inspection well to perform routine inspection, maintenance and other works when the inspection well is opened. After the grid plate is closed, the danger caused by the fact that people or animals step on the grid plate to fall into the inspection well 2 can be prevented. In order to prevent rainwater from flooding into the manhole 2, the manhole 2 of the present application is disposed to be exposed to the ground at a certain height.
In the gate control system for a drain pipe according to the present application, the controller may be, for example, a PLC (Programmable Logic Controller) controller 9 or a programmable automation controller, an edge programmable industrial controller, or the like. Taking a controller as a PLC control box 9 as an example, the controller receives signals and then controls the portable energy storage device 8 to supply power to a motor matched with the hoist 5, and the motor drives the screw rod 4 to move up and down to execute the opening or closing action of the gate 3. The PLC control box 9 feeds back the status of the field device to the control center through a wireless signal, and the feedback information includes the open or close state of the gate 3, the normal or fault state of the hoist 5, the electric quantity of the energy storage device 8, and the like. When the energy storage device 8 is in low electric quantity and the solar photovoltaic panel 7 cannot be charged in time, the control center can give an alarm prompt, and an operation and maintenance person can disassemble the energy storage device 8 to the site and bring the energy storage device 8 back to the control center for charging, so that the energy storage device 8 can be guaranteed to stably provide electric energy. The application utilizes the solar photovoltaic panel 7 to generate electricity to charge the energy storage device 8, and provides a power supply for the operation of the hoist 5. According to the gate control system for the drain pipe, the hoist 5 only needs to operate the gate 3, so that the power required by operation is low, and the energy storage device 8 can meet the electricity requirement of the hoist 5. The PLC control box 9 is used for transmitting wireless signals, so that the gate 3 is remotely controlled in a control center, and the running condition of the field equipment is fed back. The gate control system for the drain pipe solves the problems of power supply and control of the drain pipe gate which is far away from towns and difficult to access by municipal power supply, and has important significance for intelligent operation of the drain pipe network.
In some embodiments, the gate control system for a drain pipe of the present application further comprises a liquid level measuring mechanism connected to the PLC control box 9, for feeding back to the PLC control box 9 whether the water level in the inspection well 2 reaches a set value, so as to facilitate the control center in judging whether to open or close the gate 3. In a specific embodiment, the liquid level measuring mechanism can be a static pressure liquid level meter or an ultrasonic liquid level meter, and the installation position of the liquid level measuring mechanism can be set according to the working principle of the liquid level measuring mechanism. For example, when the liquid level measuring mechanism is a static pressure liquid level meter, the static pressure liquid level meter can be installed at the bottom of the inspection well 2, and a pressure sensor in the static pressure liquid level meter receives the pressure of water in the inspection well 2, and finally, the height or water level value of the water is displayed through a series of calculation and conversion. The control center judges whether the water level in the inspection well 2 reaches the water level threshold value for opening the gate 3 according to the water level or the water level value obtained by the static pressure liquid level meter, namely, when the water level in the inspection well 2 is higher than the threshold value, the control center sends an instruction for opening the gate 3 to the PLC control box 9 after feedback, and the PLC control box 9 receives signals and then controls the energy storage device 8 to supply power to the matched motor of the hoist 5, and the motor drives the screw rod 4 to move upwards to open the gate 3. When the water level in the inspection well 2 is lower than the threshold value, the control center sends an instruction for closing the gate 3 to the PLC control box 9, and the PLC control box 9 receives the signal and then controls the hoist 5 to drive the screw rod 4 to move downwards to the gate limiting position to close the gate 3.
The foregoing is merely a preferred embodiment of the present application, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present application, and these modifications and substitutions should also be considered as being within the scope of the present application.
