Description

Technical Field

[0001] The present application relates to the field of gate technology, and in particular to a large-span tide-blocking working gate. Background Art

[0002] Compared with traditional gates, tide-blocking working gates can take into account both tide-blocking and navigation functions, and are more important. For small-span tide-blocking working gates, flat lifting gates or horizontal sliding gates can be considered, but for large-span tide-blocking gates (usually defined as more than 26 meters in length), in order to meet the requirements of strength, rigidity and stability, the overall gate structure of the lifting gate structure will be very bulky, and the requirements for gate opening and closing equipment and hydraulic structures will be higher, which is not conducive to the safe operation of the gate; when the horizontal sliding gate is used in the estuary of a strong tidal surge, the sediment content of the river channel is high, and the lower walking trolley is prone to siltation, and dredging is often required, and the maintenance cost is high. Summary of the invention

[0003] The purpose of the present application is to provide a new safe and stable large-span tide-blocking working gate with low maintenance costs.

[0004] This application is achieved through the following technical solutions:

[0005] The present application provides a large-span tide-blocking working gate for use in strong tidal estuaries, comprising:

[0006] The gate body includes a lower gate body and an upper gate body which are separately arranged. The lower gate body is used to be arranged on the river bottom. The two ends of the lower gate body in the length direction are used to rotate with the gate piers on both sides of the river mouth. The lower gate body rotates with the river bottom. The upper gate body is configured to be arranged above the lower gate body. The upper gate body and the lower gate body slide and seal. The upper gate body can move relative to the lower gate body along the width direction of the river mouth.

[0007] A rotation drive device, used for driving the lower door body to rotate relative to the upper door body;

[0008] The sediment pressure sensing devices are respectively arranged on the lower door body and the upper door body, and the sediment pressure sensing devices are used to detect the sediment accumulation conditions of the lower door body and the upper door body;

[0009] A first silt cleaning device is provided at the bottom of the upper door body;

[0010] A second silt cleaning device is arranged inside the lower door body;

[0011] A controller, used to be electrically connected to the sediment pressure sensing device, the first sediment cleaning device and the second sediment cleaning device respectively;

[0012] The upper door body has an open state and a closed state. When the upper door body is in the open state, the upper door body is configured to be received in the gate storage of one of the gate piers on both sides of the estuary. At this time, the lower door body is separated from the upper door body, and the lower door body can rotate relative to the upper door body; when the upper door body is in the closed state, the two ends of the upper door body in the length direction are configured to be stuck in the gate grooves of the gate piers on both sides of the estuary. The upper door body is located above the lower door body and together they block the estuary.

[0013] According to the large-span tide-proof working gate of the embodiment of the present application, the upper door and the lower door are superimposed in structure, and the upper door is a horizontal pull-type opening or closing method, which is simple to operate and has low requirements for the upper door opening and closing equipment. In the absence of tidal surge, the upper door is opened and closed normally. When the sediment pressure sensing device senses that the sediment is seriously deposited, the controller controls the first sedimentation and sediment cleaning device and the second sedimentation and sediment cleaning device to first flush and loosen the sediment, and then the upper door operates normally. When the upper door is in an open state, the sedimentation and sediment of the lower door can be dumped by rotating the lower door, so that the upper door can be closed normally. In the case of tidal surge, the upper door is in a closed state, the valve is in a tide-proof state, and the upper door is stuck in the gate groove of the gate piers on both sides of the estuary, which has a good force on the upper door and effectively protects the buildings behind. The large-span tide-proof working gate is used for ship locks at estuaries with strong tidal surges, which can solve the problem of tidal surges at estuaries with strong tidal surges. At the same time, it overcomes the problem of serious sedimentation, and the maintenance cost is low.

[0014] According to some embodiments of the present application, the lower door body includes at least one working surface, each working surface is provided with a track for cooperating with the upper door body, the track extends along the length direction of the lower door body, and the upper door body is configured to slide with the track.

[0015] In the above scheme, the track arranged on the working surface cooperates with the upper door body to guide the movement of the upper door body and ensure that the upper door body moves flexibly and stably relative to the lower door body.

[0016] According to some embodiments of the present application, the lower door body includes two end faces and a side face, the side face is located between the two end faces, the side face is arranged around the outer peripheral wall of the end face, the side face is connected with the two end faces to form a hollow structure, the side face includes an arc surface and at least one working surface, the arc surface and all the working surfaces are arranged in sequence around the circumference of the lower door body, and the arc surface is configured to rotate with the river bottom.

[0017] In the above scheme, the arc surface rotates with the river bottom, so as to realize flexible rotation of the lower door body and the river bottom and reduce the rotation friction of the lower door body.

[0018] According to some embodiments of the present application, the side surface includes two working surfaces, and the two working surfaces are adjacently arranged along the circumference of the lower door body and have an angle therebetween.

[0019] In the above scheme, the two working surfaces are provided with spare tracks to increase the service life of the lower door body, and the two adjacent working surfaces cooperate with the upper door body in turn to save energy consumption and improve work efficiency.

[0020] According to some embodiments of the present application, the angle is 80°-100°.

[0021] In the above scheme, the selection of the angle makes it easy to dump the silt on the working surface when switching between the two working surfaces.

[0022] According to some embodiments of the present application, the angle is 90°.

[0023] In the above scheme, two adjacent working surfaces are vertically arranged so that when one of the planes is in a horizontal state, the other working surface is in a vertical state, which is convenient for dumping the accumulated silt on the working surface that is in a horizontal state before rotation. At the same time, the working surface that is in a vertical state before rotation is not conducive to silt accumulation. The accumulated silt on the working surface that is in a vertical state can be easily cleaned up through the second silt cleaning device, so as to cooperate with the upper door body after rotation.

[0024] According to some embodiments of the present application, the lower door body is a hollow structure, each working surface is provided with a sand flushing hole, the sand flushing hole connects the inside and outside of the lower door body, and the second silt cleaning device corresponds to the sand flushing hole.

[0025] In the above scheme, the sand flushing hole corresponds to the second siltation and sand cleaning device, so that the second siltation and sand cleaning device can flush out the siltation and sand on the working surface through the sand flushing hole.

[0026] According to some embodiments of the present application, a lower traveling trolley is provided at the bottom of the upper door body, and the lower traveling trolley is used to cooperate with the track to drive the upper door body to move along the track.

[0027] In the above scheme, the lower traveling trolley cooperates with the track so that the upper door body can move along the track, thereby improving the mobility of the upper door body.

[0028] According to some embodiments of the present application, a track cleaner is provided at the bottom of the upper door body, and the track cleaner is used to clean the silt deposited on the track when the upper door body is switched from an open state to a closed state.

[0029] In the above scheme, the track is cleaned by the track cleaner to facilitate the movement of the lower traveling trolley along the track and reduce the resistance of the movement of the lower traveling trolley.

[0031] In the above solution, the lower door body is supported by the support seat, thereby ensuring the overall rigidity and stability of the lower door body.

[0032] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The following describes a large-span tide-blocking working gate according to an embodiment of one aspect of the present application with reference to the drawings.

[0045] like Figure 1-Figure 4 As shown, the large-span tide-blocking working gate 100 according to the embodiment of the present application is used in estuaries with strong tidal surges. The large-span tide-blocking working gate 100 includes: a gate body, a rotation drive device 40, a silt pressure sensing device 50, a first silt cleaning device 61, a second silt cleaning device 62, and a controller.

[0046] Specifically, the gate body is used to be installed on the foundation of a strong tidal estuary, e.g. Figure 1 As shown, gate piers 20 are arranged on both sides of the estuary 90 , and a bottom foundation 30 is arranged at the bottom of the estuary 90 (referred to as the river bottom). The gate piers 20 and the bottom foundation 30 are usually concrete structures, and the bottom foundation 30 is connected to the gate piers 20 on both sides of the estuary 90 .

[0047] like Figure 1 and Figure 2 As shown, the gate body includes a lower door body 12 and an upper door body 11 which are separately arranged. The lower door body 12 is used to be arranged on the riverbed and to rotate with the riverbed (bottom foundation 30). The two ends of the lower door body 12 in the length direction are used to rotate with the gate piers 20 on both sides of the river mouth 90. For example, the two ends of the lower door body 12 are connected to the bearings buried in the gate piers 20 on both sides of the river mouth 90 through the rotating shaft 121; the upper door body 11 is configured to be arranged above the lower door body 12, and the upper door body 11 and the lower door body 12 slide and seal together. The upper door body 11 can move relative to the lower door body 12 along the width direction of the river mouth 90. It should be pointed out that the width direction of the river mouth 90 is consistent with the length direction of the lower door body 12. It can be understood that the length direction of the gate body is consistent with the width direction of the river mouth 90. In this application, Figure 1 The X in the figure represents the length direction of the lower door body 12. The rotation drive device 40 is used to drive the lower door body 12 to rotate relative to the lower door body 12, so as to provide drive for the rotation of the lower door body 12. The upper door body 11 has an open state and a closed state. When the upper door body 11 is in the open state, the upper door body 11 is configured to be received in the gate 21 of one of the gate piers 20 on both sides of the river mouth 90. At this time, the lower door body 12 is separated from the upper door body 11, and the lower door body 12 can rotate relative to the upper door body 11; when the upper door body 11 is in the closed state, the two ends of the upper door body 11 in the length direction are configured to be stuck in the gate grooves 22 of the gate piers 20 on both sides of the river mouth 90, and the upper door body 11 is located above the lower door body 12 and together blocks the river mouth 90. For example, the gate piers 20 on both sides of the estuary 90 are provided with gate slots 22 that cooperate with the upper door body 11. When the upper door body 11 is in a closed state, both ends of the upper door body 11 are in the gate slots 22, which can resist a large tidal force, so that the force (such as tidal force) on the upper door body 11 is shared by the gate piers 20 on both sides of the estuary 90, ensuring the safety of the gate body. One of the gate piers 20 on both sides of the estuary 90 is provided with a gate storage 21, and the opening of the gate storage 21 faces the other gate pier 20, so that the upper door body 11 can be stored in the gate storage 21 or driven out of the gate storage 21. On the gate pier 20 provided with the gate storage 21, the opening of the gate storage 21 is connected to the gate slot 22.

[0048] The sediment pressure sensing device 50 is respectively arranged on the lower door body 12 and the upper door body 11, and the sediment sensing device is used to detect the sediment accumulation of the lower door body 12 and the upper door body 11. The first sediment accumulation and sand cleaning device 61 is arranged at the bottom of the upper door body 11, and the second sediment accumulation and sand cleaning device 62 is arranged inside the lower door body 12, and is used to flush the sediment accumulated on the upper door body 11 and the lower door body 12. The controller is used to electrically connect the sediment pressure sensing device 50, the first sediment accumulation and sand cleaning device 61 and the second sediment accumulation and sand cleaning device 62, and is used to control the operation of the first sediment accumulation and sand cleaning device 61 and the second sediment accumulation and sand cleaning device 62 according to the sediment accumulation of the lower door body 12 and the upper door body 11 detected by the sediment pressure sensing device 50.

[0049] According to the large-span tide-blocking working gate 100 of the embodiment of the present application, an upper door body 11 and a lower door body 12 are superimposed in structure. The upper door body 11 is a horizontal pull-type opening or closing method, which is simple to operate and has low requirements for the opening and closing equipment of the upper door body 11. In the absence of tidal surge, the upper door body 11 is opened and closed normally. When the sediment pressure sensing device 50 senses that the sediment is seriously deposited, the controller controls the first sedimentation sediment cleaning device 61 and the second sedimentation sediment cleaning device 62 to first flush and loosen the sediment, and then the upper door body 11 operates normally. When the upper door body 11 is in an open state, the sedimentation sediment of the lower door body 12 can be dumped by rotating the lower door body 12, so that the upper door body 11 can be closed normally. In the case of tidal surge, the upper door body 11 is in a closed state, the valve is in a tide-blocking state, and the upper door body 11 is stuck in the gate groove of the gate piers 20 on both sides of the estuary. The force on the upper door body 11 is good, which effectively protects the buildings behind. The large-span tide-blocking working gate 100 is used for ship locks at estuaries with strong tidal surges and can solve the tide-blocking problem at estuaries with strong tidal surges. The gate can operate normally in an environment where silt is prone to serious sedimentation, can meet the requirements of ultra-high navigation clearance for seagoing vessels, and has low maintenance costs.

[0050] According to some embodiments of the present application, Figure 2As shown, the lower door body 12 includes at least one working surface 122, each working surface 122 is provided with a track 124 for cooperating with the upper door body 11, the track 124 extends along the length direction X of the lower door body 12, and the upper door body 11 is configured to slide with the track 124. The track 124 provided on the working surface 122 cooperates with the upper door body 11 to guide the movement of the upper door body 11, and ensure that the upper door body 11 moves flexibly and stably relative to the lower door body 12. It should be pointed out that in order to ensure the movement of the upper door body 11, a track is also provided at the bottom of the door storage 21 (in order to distinguish it from the track of the lower door body 12, the track at the bottom of the door storage 21 is defined as the second track), and the second track corresponds to the track 124 on the working surface 122. Similarly, a track is also provided at the bottom of the door slot 22 of the gate pier 20 where the door storage 21 is not provided (in order to distinguish it from the track of the lower door body 12, the track here is defined as the third track), and the third track corresponds to the track 124 on the working surface 122.

[0051] When ships need to pass through, the upper door 11 switches from a closed state to an open state. The upper door 11 first moves along the track 124 on the working surface 122 to the second track of the door garage 21. During the movement, the upper door 11 gradually disengages from the third track. As the upper door 11 moves, the upper door 11 completely disengages from the track 124 on the working surface 122. The upper door 11 is located inside the door garage 21. At this time, the upper door 11 is in an open state.

[0052] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the lower door body 12 includes two end faces 125 and a side face, the two end faces 125 are located at two opposite ends of the length direction X of the lower door body 12, the side face is located between the two end faces 125, the side face is arranged around the outer peripheral wall of the end face 125, and the side face is connected with the two end faces 125 to form a hollow structure; the side face includes an arc surface 123 and at least one working surface 122, the arc surface 123 and all the working surfaces 122 are arranged in sequence around the circumference of the lower door body 12, and the arc surface 123 is configured to rotate with the riverbed. It should be pointed out that when the side face includes one working surface 122, the arc surface 123 connects the two ends of the working surface 122 along the circumference of the lower door body 12; when the side face includes multiple working surfaces 122, the multiple working surfaces 122 are connected in sequence along the circumference of the lower door body 12, and the two ends of the arc surface 123 are respectively connected to the two working surfaces 122. The arc surface 123 rotates with the river bottom, so as to realize flexible rotation of the lower door body 12 and the river bottom, and reduce the rotation friction between the lower door body 12 and the bottom foundation 30.

[0053] It can be understood that the bottom foundation 30 of the riverbed is provided with an arc-shaped door groove, and the arc-shaped door groove matches the arc surface 123 of the lower door body 12.

[0054] According to some embodiments of the present application, Figure 2 As shown, the side surface includes two working surfaces 122, and the two working surfaces 122 are adjacently arranged along the circumference of the lower door body 12, and there is an angle between the two. The arrangement of the two working surfaces 122 enables the lower door body 12 to have a spare track to increase the service life of the lower door body 12, and the two adjacent working surfaces 122 are alternately matched with the upper door body 11 to avoid reciprocating rotation of the lower door body 12 when there is only one working surface 122, saving energy consumption and improving work efficiency. For example, after the lower door body 12 rotates relative to the upper door body 11, one working surface 122 is in an inclined state, which is convenient for dumping the silt and sand thereon, and the other working surface 122 rotates to a horizontal state to cooperate with the upper door body 11.

[0055] According to some embodiments of the present application, the angle is 80°-100°. The selection of the angle facilitates dumping the silt on the working surface 122 when switching between the two working surfaces 122 .

[0056] Optionally, the angle is 90°, that is, the two working surfaces 122 are arranged vertically. Figure 3 and Figure 4 As shown, when one of the working surfaces 122 is in a horizontal state, the other working surface 122 is in a vertical state. This angle selection facilitates dumping of the silt deposited on the working surface 122 that is in a horizontal state before the rotation. At the same time, the working surface 122 that is in a vertical state before the rotation is not conducive to silt depositing. The second silt deposit cleaning device 62 can easily clean the silt deposited on the working surface 122 in a vertical state, so as to facilitate cooperation with the upper door body 11 after the rotation.

[0057] According to some embodiments of the present application, the lower door body 12 is a hollow structure, and each working surface 122 is provided with a sand flushing hole, which connects the inside and outside of the lower door body 12, and the second siltation and sand cleaning device 62 is located in the lower door body 12 and corresponds to the sand flushing hole. The sand flushing hole corresponds to the second siltation and sand cleaning device 62, so that the second siltation and sand cleaning device 62 can flush the siltation and sand on the working surface 122 through the sand flushing hole.

[0058] For example, each silt cleaning device (collectively referred to as the first silt cleaning device 61 and the second silt cleaning device 62) includes a silt flushing and discharging pipeline and an air pump, and the air pump is electrically connected to the controller. When the air pump receives a working instruction from the controller, the air pump works, and the air outlet of the air pump discharges high-pressure gas through the silt flushing and discharging pipeline to disperse the silt located at the lower door body 12 and the upper door body 11.

[0059] In the second sediment cleaning device 62, one end of the sediment flushing pipe is connected to the air outlet of the air pump, and the other end of the sediment flushing pipe corresponds to the sand flushing hole. When the air pump receives the working instruction from the controller, the air pump works, and the air outlet of the air pump transports high-pressure gas through the sediment flushing pipe to the sand flushing hole to discharge the lower door body 12, thereby flushing away the sediment on the working surface 122. It should be pointed out that the sediment cleaning device can also use other driving devices, such as a high-pressure water pump.

[0060] In the first silt cleaning device 61, one end of the silt flushing pipe is connected to the air outlet of the air pump, and a nozzle is provided at the other end of the silt flushing pipe. The nozzle is arranged facing the working surface 122 of the upper door body 11 facing the lower door body 12, so as to disperse the silt on the working surface 122 when the air pump is working.

[0061] According to some embodiments of the present application, Figure 1 As shown, the rotation drive device 40 includes a rotation drive motor 41, a reducer 42, and a coupling 43. The rotation drive motor 41 is arranged in the internal installation cavity of the gate pier 20. One end of the reducer 42 is connected to the output end of the rotation drive motor 41, and the other end of the reducer 42 is connected to the coupling 43. The rotating shaft 121 located at the end of the length direction X of the lower door body 12 is connected to the coupling 43. The rotation drive motor 41 works to drive the lower door body 12 to rotate. It should be pointed out that there are two rotation drive devices 40, which are arranged at both ends of the length direction X of the lower door body 12 to ensure the stable rotation of the lower door body 12.

[0062] According to some embodiments of the present application, Figure 2 As shown, a lower walking trolley 111 is provided at the bottom of the upper door body 11, and the lower walking trolley 111 is used to cooperate with the track 124 to drive the upper door body 11 to move along the track 124. Please refer to the walking trolley in the prior art for the structure of the lower walking trolley 111, and this application will not provide a detailed introduction. The lower walking trolley 111 cooperates with the track 124 to facilitate the upper door body 11 to move along the track 124, thereby improving the mobility of the upper door body 11. When the upper door body 11 enters the gatehouse 21, the lower walking trolley 111 cooperates with the second track set in the gatehouse 21 and moves on the second track; similarly, when the upper door body 11 enters the gate slot 22 of the gate pier 20 where the gatehouse 21 is not set, the lower walking trolley 111 cooperates with the third track.

[0063] According to some embodiments of the present application, an upper traveling trolley is provided at the top of the upper door body 11. The upper traveling trolley is provided at one end of the upper door body 11 close to the door storage 21 along the length direction of the upper door body 11. The driving device of the upper door body 11 adopts a rack and pinion driving device 80. The rack and pinion driving device 80 is provided at the top of the door storage 21. The rack and pinion driving device 80 includes a driving motor, a gear and a rack. For example, the driving motor is installed at the top of the door storage 21, the gear is installed at the output end of the driving motor, the rack is installed at the top of the upper door body 11, the gear is meshed with the rack, the driving motor is electrically connected to the controller, and the controller can control the driving motor to work so that the driving motor drives the gear to rotate, thereby driving the upper door body 11 to move relative to the door storage. In order to ensure the stable movement of the upper door body 11, two rack and pinion driving devices 80 are provided, and the two rack and pinion driving devices 80 are distributed on both sides of the thickness direction Y of the upper door body 11.

[0064] According to some embodiments of the present application, Figure 1 As shown, the gate pier 20 without a door garage is provided with a limit switch 23, and the limit switch 23 is electrically connected to the controller. When the upper door body 11 moves into the door groove of the gate pier 20 without a door garage, when the upper door body 11 contacts the limit switch 23, the limit switch 23 sends a stop signal to the controller, and the controller controls the drive motor to stop working according to the stop signal of the limit switch 23, so that the upper door body 11 stops moving.

[0065] According to some embodiments of the present application, a track cleaner is provided at the bottom of the upper door body 11, and the track cleaner is used to clean the silt deposited on the track 124 when the upper door body 11 is switched from the open state to the closed state. The track 124 is cleaned by the track cleaner to facilitate the movement of the lower trolley 111 along the track 124, thereby reducing the resistance of the movement of the lower trolley 111.

[0066] For example, the track cleaner includes a cleaning brush, which is arranged at the end of the upper door body 11 in the length direction, and the cleaning brush corresponds to the track 124. When the upper door body 11 moves relative to the lower door body 12, the cleaning brush can remove the silt accumulated on the track 124.

[0067] According to some embodiments of the present application, the large-span tide-blocking working gate 100 further includes at least one support seat 70, each support seat 70 is used to be arranged on the river bottom (bottom foundation 30), the lower door body 12 is provided with a groove corresponding to the support seat 70, the support seat 70 is configured to be inserted into the corresponding groove, and the support seat 70 is rotatably sealed with the lower door body 12. A support shaft is provided in the groove, and the support seat 70 is supported by the support shaft and rotatably cooperates with the support shaft.

It should be noted that the control principle of the controller and other electrical components of the present application can refer to the control principle of electrical components in the prior art, and this application will not be described in detail.

[0071] According to some embodiments of the present application, the electrical components in the present application are all electrically connected to an external power source to ensure the normal operation of each electrical component. The external power source can be provided with a power interface at the gate pier 20 of the estuary 90 to facilitate power supply.

[0072] According to some embodiments of the present application, the span of the gate body of the present application is greater than 30m and greater than the span of the estuary, so as to be suitable for large-span estuaries.

[0073] The working principle of the large-span tide-blocking working gate 100 according to the embodiment of the present application is:

[0074] In the absence of tidal surge, the large-span tide-blocking working gate 100 is opened and closed normally. When the sediment pressure sensing device 50 senses that the sediment is seriously deposited, the lower door body 12 will first disperse the deposited sediment by opening the second sediment cleaning device 62, and then rotate the lower door body 12 to dump the deposited sediment on the working surface 122 to facilitate the normal operation of the upper door body 11; in the presence of tidal surge, the large-span tide-blocking working gate 100 is in a closed state, and the upper door body 11 is in a closed state, with both ends of the upper door body 11 stuck in the gate grooves of the gate piers 20 on both sides of the estuary.

[0075] The first silt cleaning device 61 and the second silt cleaning device 62 are used to flush the silt, and then the silt on the lower door body 12 is dumped by rotating the lower door body 12, so that the upper door body 11 can move normally relative to the lower door body 12, thereby reducing the movement resistance. The large-span tide-blocking working gate 100 is used to solve the tide-blocking problem of a large-span strong tidal estuary and overcome the problem of serious silt accumulation.

[0076] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
