Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and in particular to a dry gate at a crossing. Background Technology

[0002] Wharves, ferry crossings, and traffic routes along flood control dikes adjacent to river and sea cities must be equipped with access points to facilitate the passage of pedestrians and vehicles both inside and outside the dike. During flood or high tide, these access points need to be protected against flooding and tides, requiring the construction of sluice gates to connect with the flood control dike and form a closed flood control system. These land-based traffic gates and flood control / tide-blocking gates are commonly referred to as dry gates.

[0003] In related technologies, Chinese utility model patent with announcement number CN211646286U discloses a flood control gate mechanism, including a left gate pier, a right gate pier, and a gate bottom plate. The gate bottom plate is integrated with the bottom ends of the left and right gate piers respectively. Vertical gate slots are opened on the opposite side walls of the left and right gate piers. Gate plates are installed between the gate slots. Bottom waterstops are provided at the bottom of the gate plates. Side waterstops are installed on the side walls of the gate slots near the back water surface of the gate plates. Pre-tightening devices are installed on the side walls of the gate slots near the front water surface of the gate plates. The pre-tightening devices are used to provide pre-tightening pressure for the gate plates.

[0004] Regarding the aforementioned technologies, the inventors believe that when floods occur, operators need to manually close the gates. Since the gates are located at the entrance of the channel, operators need to be on-site to close them. In the event of sudden natural disasters such as floods, operators cannot close the gates in time, which reduces the flood control efficiency of the gates. Summary of the Invention

[0005] In order to improve the flood control efficiency of the gate, this application provides a dry gate at the crossing.

[0006] The technical solution for a level crossing dry gate provided in this application is as follows:

[0007] A level crossing gate includes a gate and a mounting column installed on the side of the gate. A floating plate is mounted on the mounting column, and multiple floats are mounted on the floating plate. A movable block passes through the mounting column, and a movable plate is fixedly connected to the movable block. The movable plate is fixedly connected to the floating plate. A movable groove is formed on the mounting column for sliding cooperation with the movable plate. A positioning rod passes through the mounting column, and a positioning disc is fixedly sleeved on the positioning rod. A positioning groove is formed on the mounting column for sliding cooperation with the positioning disc. A positioning spring is fixedly connected to the positioning disc, and the end of the positioning spring away from the positioning disc is fixedly connected to the inner end face of the positioning groove. An activation groove is formed on the movable block for insertion cooperation with the positioning rod. A fixing rod is installed on the end of the positioning rod away from the movable block. A fixing slot is formed on the gate for insertion cooperation with the fixing rod.

[0008] By adopting the above technical solution, when a flood occurs, the rising water level causes the float to move, which in turn causes the floating plate to move, which in turn causes the moving plate to move, and the moving plate to move the moving block. At this time, the positioning rod slides on the side wall of the moving block, and the positioning spring is in a compressed state. When the positioning rod moves to the position of the starting slot, it is inserted into the starting slot under the action of the positioning spring. The movement of the positioning rod causes the fixed rod to move, and the fixed rod moves away from the fixed slot, thereby releasing the fixed state of the gate. The gate closes under the action of gravity, thus enabling the gate to close in time and connect with the flood control dike to form a closed flood control system, improving the flood control efficiency of the gate.

[0009] Preferably, a pressure rod is provided on the mounting column, the end of the pressure rod that enters the mounting column is fixedly connected to the moving block, a pressure disc is installed on the end of the pressure rod that exits the mounting column, an inclined surface is provided on the end of the positioning rod near the moving block, and a lifting assembly for lifting the gate is provided on the mounting column.

[0010] By adopting the above technical solution, the operator raises the gate using the lifting assembly. Then, the operator presses the pressure disc, which moves the pressure rod, which in turn moves the moving block. The moving block slides on the inclined surface of the positioning rod, and the positioning rod moves away from the starting slot under the action of the inclined surface. The movement of the positioning rod moves the positioning disc, which compresses the positioning spring. The positioning rod then moves the fixing rod, which inserts into the fixing slot, thereby fixing the gate and facilitating repeated use by the operator.

[0011] Preferably, the lifting assembly includes a lifting sprocket mounted on the gate and a drive chain mounted on the mounting column. The lifting sprocket meshes with the drive chain. A drive sprocket is rotatably mounted inside the mounting column. A driven sprocket is rotatably mounted at the end of the mounting column away from the drive sprocket. The drive chain is wound around the drive sprocket and the driven sprocket. A drive assembly for driving the drive sprocket to rotate is provided on the mounting column.

[0012] By adopting the above technical solution, the operator uses the drive assembly to drive the drive sprocket to rotate, the drive sprocket to rotate, the drive chain to move, the drive chain to move the lifting sprocket, and the lifting sprocket to move the gate, thus facilitating the operator to lift the gate.

[0013] Preferably, the drive assembly includes a worm gear mounted on the drive sprocket and a worm passing through the mounting post. The worm meshes with the worm gear, and a handwheel is fixedly connected to the end of the worm that extends out of the mounting post.

[0014] By adopting the above technical solution, the operator turns the handwheel, which drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the drive sprocket to rotate, thereby lifting the gate.

[0015] Preferably, a drive rod is fixedly threaded through the lifting sprocket, a stop gear is fixedly sleeved on the end of the drive rod away from the lifting sprocket, a stop rack is threaded through the gate, the stop rack meshes with the stop gear, a stop groove is formed on the inner wall of the fixed slot for sliding engagement with the stop rack, and a control component is provided on the gate for controlling the stop rack to abut against the stop gear.

[0016] By adopting the above technical solution, initially, the stop rack and stop gear are not tightly engaged. The float moves the fixed rod away from the fixed slot through the moving block, and the gate falls under the action of gravity. The falling gate causes the lifting sprocket to roll on the chain, thus facilitating the gate's descent. The operator uses the control components to engage the stop rack and stop gear, preventing the stop gear from rotating. This prevents the lifting sprocket from rotating. Then, the operator turns the handwheel, which drives the worm gear to rotate through the worm. The worm gear drives the drive chain through the drive sprocket, which in turn drives the lifting sprocket, which in turn moves the gate, thus facilitating the operator's lifting of the gate.

[0017] Preferably, the control component includes a control block slidably disposed on the inner wall of the fixed slot and a control plate passing through the gate. The control block can abut against the side of the stop rack away from the stop gear. The control plate passes through the gate and is fixedly connected to the control block. The gate has a control groove for sliding cooperation with the control plate. The control block has an inclined surface, and the stop rack has an inclined surface. The inclined surface on the control block matches the inclined surface on the stop rack.

[0018] By adopting the above technical solution, after the gate is lowered, the operator moves the control plate, which moves the control block. The inclined surface of the control block slides on the inclined surface of the stop rack. The operator continues to move the control plate, which moves the control block to slide on the side of the stop rack. The control block presses against the stop rack, so that the stop rack abuts and meshes with the stop gear, thereby fixing the lifting sprocket and making it convenient for the operator to lift the gate.

[0019] Preferably, the positioning rod has a fixed groove on its end face near the control block for sliding cooperation with the fixed rod. A fixed spring is fixedly connected to the fixed rod. The end of the fixed spring away from the fixed rod is fixedly connected to the inner end face of the fixed groove. The fixed rod can abut against the control block and abut against the side of the stop rack away from the stop gear.

[0020] By adopting the above technical solution, when the gate is lifted, the operator moves the positioning rod by using the pressure disc. The movement of the positioning rod compresses the fixing spring, and the fixing rod abuts against the side wall of the gate under the action of the fixing spring. The fixing rod slides on the side wall of the gate. When the fixing rod moves to the position of the fixing slot, the fixing rod inserts into the fixing slot under the action of the fixing spring. The fixing rod abuts against the control block, and the fixing rod drives the control block to move under the action of the positioning rod. The control block is then reset, which is convenient for the operator to use repeatedly.

[0021] Preferably, a locking rod is provided on the end of the mounting post away from the fixing rod, the locking rod can be inserted into the fixing slot, the end of the locking rod extending into the fixing slot can abut against the control block, and the mounting post is provided with a moving component for driving the locking rod to move.

[0022] By adopting the above technical solution, after the gate is lowered, the operator uses the moving component to move the locking rod, which is then inserted into the fixed slot to fix the gate and prevent it from loosening and affecting the flood control effect. When the operator needs to lift the gate, the operator moves the control panel, which moves the control block. The control block abuts against the locking rod, and the movement of the control block moves the locking rod, which is then pushed out of the fixed slot, thus unlocking the gate and facilitating the operator to lift it.

[0023] Preferably, the movable component includes a rotating column rotatably mounted inside the mounting column, a movable gear fixedly sleeved on the rotating column, a locking rod having teeth that mesh with the teeth on the movable gear, a plurality of baffles fixedly connected to the end of the rotating column away from the movable gear, a vortex groove for sliding cooperation with the baffles being provided on the mounting column, and a flow groove for water to flow through being provided on the mounting column, the flow groove being connected to the vortex groove.

[0024] By adopting the above technical solution, when the gate is lowered, the water flow is lifted by the gate's obstruction, causing some water to flow out through the flow channel. The water flow in the flow channel, under the action of water pressure, drives the baffle to move. The movement of the baffle drives the rotating column to rotate, which in turn drives the moving gear to rotate. The rotation of the moving gear causes the locking rod to insert into the fixed slot, thereby fixing the gate. The locking rod, inserted into the fixed slot, abuts against the control block, causing the moving gear to stop rotating. The stopping of the moving gear prevents the rotating column from rotating, and the inability of the rotating column to rotate prevents the baffle from moving. The vortex channel, blocked by the baffle, prevents water from flowing out from the other end, making it convenient for operators to use.

[0025] Preferably, a locking rod is provided on the mounting post, and a locking groove is provided on the mounting post for sliding cooperation with the locking rod. A locking spring is fixedly connected to the locking rod, and the end of the locking spring away from the locking rod is fixedly connected to the inner end face of the locking groove. A plurality of locking slots are provided on the rotating post for insertion cooperation with the locking rod. A locking gear is rotatably mounted on the mounting post, and the locking rod is provided with teeth that mesh with the locking gear. A transmission rack is provided on the mounting post and meshes with the locking gear. An inclined surface is provided on the end of the transmission rack that protrudes from the mounting post.

[0026] By adopting the above technical solution, when the gate falls, the transmission rack moves under the action of the inclined plane. The movement of the transmission rack drives the locking gear to rotate, and the rotation of the locking gear drives the locking rod to move away from the locking slot. At this time, the locking spring is in a compressed state, thereby releasing the locking state of the rotating column, making it convenient for the operator to fix the fallen gate. When the operator lifts the gate, the locking rod is inserted into the locking slot under the action of the locking spring, thereby fixing the rotating column and preventing the locking rod from extending due to the rotation of the rotating column, which would prevent the gate from falling. This makes it convenient for the operator to use.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When a flood occurs, the rising water level causes the float to move, which in turn causes the floating plate to move, which in turn causes the moving plate to move, which in turn causes the moving block to move. At this time, the positioning rod slides on the side wall of the moving block, and the positioning spring is in a compressed state. When the positioning rod moves to the position of the starting slot, it is inserted into the starting slot under the action of the positioning spring. The movement of the positioning rod causes the fixed rod to move, and the fixed rod moves away from the fixed slot, thereby releasing the fixed state of the gate. The gate closes under the action of gravity, which allows the gate to close in time and connect with the flood control dike to form a closed flood control system, improving the flood control efficiency of the gate.

[0029] 2. Initially, the stop rack and stop gear are not engaged. The float moves the fixed rod away from the fixed slot via the moving block, and the gate falls under gravity. The falling gate causes the lifting sprocket to roll on the chain, thus facilitating the gate's descent. The operator uses the control components to engage the stop rack and stop gear, preventing the stop gear from rotating. This prevents the lifting sprocket from rotating. Then, the operator turns the handwheel, which drives the worm gear to rotate via the worm. The worm gear drives the drive chain via the drive sprocket, which in turn drives the lifting sprocket, which in turn moves the gate, thus facilitating the operator's lifting of the gate.

[0030] 3. When the gate is lowered, the water flow is lifted by the gate's obstruction, causing some water to flow out through the flow channel. The water flow in the flow channel, under the action of water pressure, drives the baffle to move. The movement of the baffle drives the rotating column to rotate, which in turn drives the moving gear to rotate. The rotation of the moving gear causes the locking rod to insert into the fixed slot, thereby fixing the gate. The locking rod, inserted into the fixed slot, abuts against the control block, causing the moving gear to stop rotating. The moving gear's cessation of rotation prevents the rotating column from rotating, which in turn prevents the baffle from moving. The vortex channel, blocked by the baffle, prevents water from flowing out from the other end, making it convenient for operators to use. Attached Figure Description

The movable groove 141 is vertically formed, and the inner sidewall of the movable groove 141 slides in engagement with the outer sidewall of the movable plate 14.

[0043] Reference Figure 2 A pressure rod 152 is fixedly connected to the movable block 15. The pressure rod 152 is vertically arranged and passes through the mounting column 11. The end of the pressure rod 152 that passes through the mounting column 11 is fixedly connected to the movable block 15. A pressure disc 153 is fixedly connected to the end of the pressure rod 152 that exits the mounting column 11. An activation groove 151 is provided on the movable block 15. The activation groove 151 is vertically opened and is located on the side of the movable block 15 near the gate 1.

[0044] Reference Figure 3 A positioning rod 16 is installed on the mounting column 11. The positioning rod 16 is horizontally positioned, and the end of the positioning rod 16 away from the gate 1 can be inserted into the starting groove 151. The end of the positioning rod 16 that extends into the starting groove 151 is provided with an inclined surface. A positioning disc 161 is provided on the positioning rod 16. The positioning disc 161 is vertically positioned and is mounted on the positioning rod 16. The positioning disc 161 is sleeved on the positioning rod 16 and is fixedly connected to the positioning rod 16.

[0045] Reference Figure 3 The mounting column 11 is provided with a positioning groove 162, which is horizontally opened. The inner side wall of the positioning groove 162 slides and engages with the outer side wall of the positioning disc 161. A positioning spring 163 is provided on the positioning rod 16.

One end of the positioning spring 163 is fixedly connected to the positioning disc 161, and the other end of the positioning spring 163 is fixedly connected to the inner end face of the positioning groove 162.

[0046] When a flood occurs, the rising water level causes the float 13 to move. The float 13 then moves the moving plate 14 via the floating plate 12. The moving plate 14 then moves the moving block 15. At this time, the positioning spring 163 is in a compressed state. When the positioning rod 16 moves to the position of the starting slot 151, the positioning rod 16 is inserted into the starting slot 151 under the action of the positioning spring 163. The movement of the positioning rod 16 causes the fixed rod 17 to move away from the fixed slot 171, thereby releasing the fixed state of the gate 1. The gate 1 closes under the action of gravity, thus enabling the gate 1 to close in time and connect with the flood control dike to form a closed flood control system, improving the flood control efficiency of the gate 1.

[0047] Reference Figure 3 A fixing rod 17 is provided on the end of the positioning rod 16 near the gate 1. The fixing rod 17 is horizontally positioned and passes through the positioning rod 16. A fixing groove 172 is provided on the positioning rod 16, and the outer side wall of the fixing rod 17 slides in engagement with the inner side wall of the fixing groove 172.

One end of the fixing spring 173 is fixedly connected to the fixing rod 17, and the other end of the fixing spring 173 is fixedly connected to the inner end face of the fixing groove 172. A fixing slot 171 is provided on the gate 1, and the inner side wall of the fixing slot 171 slides in engagement with the outer side wall of the fixing rod 17.

[0048] The operator presses the pressure disc 153, which drives the moving block 15 to move via the pressure rod 152. The moving block 15 moves the positioning rod 16 via the inclined plane. The movement of the positioning rod 16 causes the fixed rod 17 to abut against the gate 1. The fixed spring 173 is in a compressed state. When the gate 1 is lifted, the fixed rod 17 moves to the position of the fixed slot 171. Under the action of the fixed spring 173, the fixed rod 17 is inserted into the fixed slot 171, thus facilitating the reset of the control block 31.

[0049] Reference Figure 4 , Figure 5 A drive sprocket 23 is mounted on the mounting column 11. The drive sprocket 23 is vertically positioned and rotatably mounted on the mounting column 11. A driven sprocket 24 is mounted at the bottom of the mounting column 11. The driven sprocket 24 is vertically positioned and rotatably mounted on the mounting column 11. A lifting assembly 2 for lifting the gate 1 is mounted on the mounting column 1. The lifting assembly 2 includes a lifting sprocket 21 and a drive chain 22. The lifting sprocket 21 is vertically positioned and passes through the gate 1. The lifting sprocket 21 is rotatably mounted inside the gate 1 and has a drive rod 211 mounted on it.

[0050] Reference Figure 3 , Figure 4 The drive rod 211 is horizontally positioned and passes through the lifting sprocket 21, being fixedly connected to it. The axis of the drive rod 211 coincides with the axis of the lifting sprocket 21. A stop gear 212 is mounted on the drive rod 211. The stop gear 212 is vertically positioned and sleeved on the drive rod 211, being fixedly connected to it. A stop rack 213 is mounted on the gate 1, horizontally positioned, and meshes with the stop gear 212. A stop groove 214 is formed on the inner wall of the fixing slot 171, and the inner side wall of the stop groove 214 slides and engages with the outer side wall of the stop rack 213.

[0051] Reference Figure 3 The gate 1 is equipped with a control assembly 3 for controlling the engagement of the stop rack 213 and the stop gear 212. The control assembly 3 includes a control block 31 and a control plate 32. The control block 31 is horizontally positioned, and its outer sidewall slides into the inner sidewall of the fixing slot 171. The end of the control block 31 near the mounting post 11 can abut against the fixing rod 17. The end of the control block 31 near the fixing rod 17 has a bevel, and the stop rack 213 also has a bevel, which matches the bevel on the control block 31.

[0052] Reference Figure 1 , Figure 3 The control plate 32 is rectangular and horizontally positioned. It passes through the gate 1 and is fixedly connected to the control block 31. A control groove 33 is provided on the inner wall of the fixing slot 171. The inner wall of the control groove 33 slides and engages with the outer wall of the control plate 32.

[0053] Reference Figure 4 , Figure 5 The drive chain 22 is vertically arranged and wound between the drive sprocket 23 and the driven sprocket 24. The drive chain 22 meshes with the lifting sprocket 21. A support plate 26 is provided on the side of the drive sprocket 23 away from the lifting sprocket 21. The support plate 26 is vertically arranged and fixedly connected to the mounting column 11. The support plate 26 abuts against the side of the drive chain 22 away from the lifting sprocket 21.

[0054] Reference Figure 5 A drive assembly 25 for driving the drive sprocket 23 to rotate is provided on the mounting post 11. The drive assembly 25 includes a worm gear 251 and a worm 252. The worm gear 251 is vertically arranged and mounted on the drive sprocket 23, with its axis coinciding with the axis of the drive sprocket 23. The worm 252 is vertically arranged and passes through the mounting post 11, meshing with the worm gear 251. A handwheel 253 is fixedly connected to the end of the worm 252 that protrudes from the mounting post 11.

[0055] When a flood occurs, the rising water level causes the float 13 to move. The movement of the float 13 causes the fixed rod 17 to move away from the fixed slot 171, and the stop rack 213 disengages from the fixed rod 17. The stop gear 212 rotates under the gravity of the gate 1. The rotation of the stop gear 212 causes the lifting sprocket 21 to rotate, thus allowing the gate 1 to fall without obstruction. After the flood recedes, the operator moves the control plate 32. The movement of the control plate 32 causes the control block 31 to move. The control block 31 abuts against the stop rack 213, thus making the stop rack 213 and the stop gear 212 abut together. The stop gear 212 cannot rotate, thus preventing the lifting sprocket 21 from rotating. Then the operator turns the handwheel 253. The handwheel 253 drives the worm gear 251 to rotate through the worm 252. The worm gear 251 drives the drive chain 22 to move through the drive sprocket 23. The drive chain 22 drives the gate 1 to lift through the lifting sprocket 21.

[0056] The operator presses the pressure disc 153, which drives the moving block 15 to move via the pressure rod 152. The moving block 15 moves the positioning rod 16 via the inclined plane. The movement of the positioning rod 16 causes the fixing rod 17 to abut against the gate 1. The fixing spring 173 is in a compressed state. When the gate 1 is lifted, the fixing rod 17 moves to the position of the fixing slot 171. Under the action of the fixing spring 173, the fixing rod 17 is inserted into the fixing slot 171, thereby fixing the gate 1 and resetting the control block 31, which is convenient for the operator to use repeatedly.

[0057] Reference Figure 2 , Figure 6 A locking rod 18 is provided on the mounting post 11. The locking rod 18 is horizontally positioned and located at the end of the mounting post 11 away from the fixing rod 17. The locking rod 18 passes through the inner wall of the mounting groove 111, and its side wall can slide and engage with the inner side wall of the fixing slot 171. The end of the locking rod 18 that enters the fixing slot 171 can abut against the control block 31, and its side wall can abut against the stop rack 213.

[0058] Reference Figure 2 , Figure 6 The mounting column 11 is equipped with a moving assembly 4 for driving the locking lever 18 to move. The moving assembly 4 includes a rotating column 41 and a moving gear 42. The rotating column 41 is a circular column, vertically arranged, and passes through the mounting column 11. The rotating column 41 is rotatably connected to the mounting column 11. A baffle 43 is provided on the rotating column 41. The baffle 43 is a rectangular plate, vertically arranged, and multiple baffles 43 are evenly arranged around the axis of the rotating column 41. The baffles 43 are fixedly connected to the rotating column 41.

The locking rod 19 is horizontally positioned, and a locking groove 191 is formed on the mounting post 11. The side wall of the locking rod 19 slides and engages with the inner side wall of the locking groove 191. A locking spring 192 is provided on the locking rod 19. The locking spring 192 is horizontally positioned and located within the locking groove 191. One end of the locking spring 192 is fixedly connected to the locking rod 19, and the other end is fixedly connected to the inner end face of the locking groove 191. A locking slot 193 is formed on the rotating post 41. Multiple locking slots 193 are evenly arranged around the outer circumference of the rotating post 41, and the inner wall of the locking slot 193 slides and engages with the outer side wall of the locking rod 19.

[0062] Reference Figure 2 , Figure 6 A locking gear 194 is provided on the mounting post 11. The locking gear 194 is vertically arranged and rotatably mounted on the mounting post 11. The locking rod 19 has teeth, and the locking gear 194 meshes with the locking rod 19. A transmission rack 195 is provided on the mounting post 11. The transmission rack 195 is horizontally arranged and meshes with the locking gear 194. The transmission rack 195 passes through the inner wall of the mounting groove 111, and the end of the transmission rack 195 that passes through the inner wall of the mounting groove 111 has an inclined surface.

[0063] When a flood occurs, gate 1 falls under the action of float 13. The fall of gate 1 causes the transmission rack 195 to move under the action of the inclined plane. The transmission rack 195 drives the locking rod 19 to move through the locking gear 194. The locking rod 19 moves away from the locking slot 193. At this time, the locking spring 192 is in a compressed state, thereby releasing the fixed state of the rotating column 41. The rotating column 41 rotates under the action of the water flow in the flow channel 45. The rotating column 41 drives the locking rod 18 to move through the moving gear 42, locking the gate. The lever 18 is inserted into the fixed slot 171, thereby locking the gate 1 and preventing the gate 1 from loosening. The operator moves the control panel 32, which drives the locking lever 18 away from the fixed slot 171 through the control block 31. Then, the operator drives the gate 1 to lift through the handwheel 253. When the transmission rack 195 moves away from the side wall of the gate 1, the locking lever 19 is inserted into the locking slot 193 under the action of the locking spring 192, thereby fixing the rotating column 41 and preventing the locking lever 18 from extending and obstructing the gate 1 from falling.

[0064] The implementation principle of a dry gate at a crossing according to an embodiment of this application is as follows: When a flood occurs, the water level rises, causing the float 13 to move. The float 13 releases the locking state of the gate 1 through the fixed rod 17, and the gate 1 falls. The water flows through the flow channel 45, causing the rotating column 41 to rotate. The rotating column 41 locks the gate 1 through the locking rod 18, so that the gate 1 can be closed in time and connected with the flood control dike to form a closed flood control system, thereby improving the flood control efficiency of the gate 1.

[0065] After the flood recedes, the operator presses down the pressure disc 153. The pressure disc 153 moves the positioning rod 16 via the moving block 15. The movement of the positioning rod 16 causes the fixing rod 17 to abut against the side wall of the gate 1. At this time, the fixing spring 173 is in a compressed state. Then, the operator moves the control block 31 via the control plate 32. The movement of the control block 31 causes the stop rack 213 to abut against the stop gear 212, and the lifting sprocket 21 is fixed. The movement of the control block 31 causes the locking rod 18 to move away from the fixing slot 171, thereby releasing the lock of the gate 1. Then, the operator turns the handwheel 253. The handwheel 253 drives the gate 1 to lift via the drive chain 22. When the fixing slot 171 moves to the position of the fixing rod 17, the fixing rod 17 is inserted into the fixing slot 171 under the action of the fixing spring 173. The control block 31 is reset, thus facilitating repeated use by the operator.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
