Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly relates to a gate locking structure without power and a using method thereof. Background Art

[0002] At present, the common gate locking method is to use a manual locking beam and manually release the lock. However, with the development of digitalization and intelligentization, hydropower stations are gradually implementing remote control, reduced staffing or unmanned operation, and the manual unlocking method appears to be backward.

[0003] Currently, the improvement methods of the locking beam are mainly to add a power device to drive the locking beam. Only the driving method is different from the movement method of the locking beam. However, adding a power device requires setting new lines and reserving installation space, and the transformation cost is relatively high.

[0004] The patent application document with the publication number CN104133550A discloses a locking method and device for a large gate. Travel devices are installed at both ends of the gate locking beam, and tracks are installed on both sides of the gate slot. A reduction motor is used to drive the locking beam to reciprocate along the track, and combined with a spring and a support plate structure, automation and remote control are realized.

[0005] The patent application document with the publication number CN220013581U discloses a locking mechanism for an accident gate at the water inlet of a hydropower station power generation tunnel, which is an accident gate locking mechanism including symmetrically arranged driving devices and locking trolleys. The locking trolleys are driven by electric telescopic rods to lock and unlock below and on both sides of the gate, and combined with limit switches and power-off switches, automation and remote control are realized.

[0006] However, both of the above two patent application documents need to set up a power system to automatically lock the gate. Summary of the Invention

[0007] To solve the above technical problems, the invention provides a gate locking structure without power and a using method thereof.

[0008] The invention is achieved through the following technical solutions.

[0009] A gate locking structure without power provided by the invention includes a locking plate, an unlocking plate, a gate side beam and a locking mechanism. The locking plate and the unlocking plate are respectively connected to the gate side beam, and the locking mechanism is connected to the gate locking platform.

[0010] Preferably, a chute is arranged on the gate side beam, and the unlocking plate extends into the chute through a sliding rod and is slidably connected to the gate side beam.

[0011] Preferably, the locking mechanism includes a locking beam and a locking member, and the locking beam is connected to the gate locking platform through the locking member.

[0012] Preferably, an inclined surface is provided on one side of the locking beam, and the locking beam and the locking member are vertically arranged.

[0013] Preferably, the locking member includes a connecting rod, an elastic member and a fixing member. One end of the connecting rod is fixedly connected to the locking beam, the other end of the connecting rod extends into the fixing member and is slidably connected therein, and the connecting rod passes through the elastic member and is slidably connected.

[0014] Preferably, the diameter of the elastic member is smaller than the diameter of the fixing member.

[0015] Preferably, a first arc surface is provided on one side of the locking plate, and a first platform is provided on the other side of the locking plate.

[0016] Preferably, a second arc surface is provided on one side of the unlocking plate, and a second platform is provided on the other side of the unlocking plate.

[0017] A method for using a gate locking structure without power includes the following steps:

[0018] S1: When the gate needs to be locked, the hoist lifts the gate upward. The first arc surface on the outside of the locking plate contacts the inclined surface of the locking beam. The gate continues to be lifted, causing the locking beam to move away from the locking plate and compress the elastic member. When the bottom of the locking plate is higher than the top surface of the locking beam, the locking beam is pushed under the locking plate between the first platform and the second platform under the action of the elastic member. At this time, the hoist lowers the gate to complete the locking of the gate.

[0019] S2: When the gate needs to be unlocked, the hoist lifts the gate upward. The second arc surface on the outside of the unlocking plate contacts the inclined surface of the locking beam. The gate continues to be lifted, causing the locking beam to move away from the unlocking plate and compress the elastic member. Before the locking beam disengages from the unlocking plate, operate the hoist to lower the gate. The locking beam catches the unlocking plate and moves upward. When the unlocking plate contacts the locking plate, the first platform and the second platform fit together, and the first arc surface and the second arc surface combine into an arc surface. Under the action of the self-weight of the gate, the locking beam can smoothly move from the unlocking plate to the locking plate. Then continue to lower the gate, and the locking beam slides along the first arc surface of the locking plate to a balanced state to complete the unlocking operation of the gate.

[0020] The beneficial effects of the present invention are as follows:

[0021] The locking device of the present invention does not need to add an external power device such as electricity, hydraulics or diesel. The locking and unlocking operations can be completed by using the original gate hoist as the power source. There is no need for manual operation of the gate locking specifically, which can reduce the labor intensity of workers and improve the working efficiency of gate locking and unlocking.

[0022] The locking device of the present invention can be used at the gate far from the core power supply area or on the platform that will be flooded, avoiding the situation of increasing the power supply cost due to the long power supply distance and solving the problem that the powered equipment cannot be immersed in water.

Detailed Embodiment

[0035] The technical solution of the present invention will be further described below, but the scope of protection is not limited thereto.

[0036] Embodiment:

[0037] As Figures 1 to 3As shown in the figure, a power-free gate locking structure includes a locking plate 1, an unlocking plate 2, a gate side beam 3 and a locking mechanism. The locking plate 1 and the unlocking plate 2 are respectively connected to the gate side beam 3, and the locking mechanism is connected to the gate locking platform 5, and the gate locking platform 5 is a gate slot.

[0038] A vertical chute 31 is provided on the gate side beam 3. The unlocking plate 2 is slidably connected to the gate side beam 3 by a slide bar extending into the chute 31. In the natural state, the unlocking plate 2 is located about 500 mm below the locking plate 1 under the action of gravity, so as to provide a space for the locking beam 4 to extend between the locking plate 1 and the unlocking plate 2.

[0039] The locking mechanism includes a locking beam 4 and a locking member. The locking beam 4 is connected to the gate locking platform 5 by the locking member.

[0040] An inclined surface 41 is provided on the side of the locking beam 4 away from the gate locking platform 5, and the locking beam 4 and the locking member are vertically arranged. The inclined surface 41 is far from the gate side beam 3 below, close to the gate side beam 3 above, and the bottom surface of the inclined surface 41 is located outside the side of the second platform 22 away from the gate side beam 3 to avoid the second platform 22 interfering with the downward movement of the locking beam 4.

[0041] The locking member includes a connecting rod 6, an elastic member 7 and a fixing member 8. One end of the connecting rod 6 is fixedly connected to the locking beam 4, the other end of the connecting rod 6 extends into the fixing member 8 and is slidably connected, the connecting rod 6 passes through the elastic member 7 and is slidably connected, and one end of the fixing member 8 is connected to the top surface of the gate locking platform 5.

[0042] The diameter of the elastic member 7 is smaller than the diameter of the fixing member 8.

[0043] A first arc surface 11 is provided on one side of the locking plate 1, and a first platform 12 is provided on the other side of the locking plate 1.

[0044] A second arc surface 21 is provided on one side of the unlocking plate 2, and a second platform 22 is provided on the other side of the unlocking plate 2.

[0045] A method for using a power-free gate locking structure includes the following steps:

[0046] S1: As Figures 4 to 7 shown in the figure, when the gate needs to be locked, the hoist lifts the gate upward. The first arc surface 11 outside the locking plate 1 contacts the inclined surface 41 of the locking beam 4. The gate continues to be lifted to move the locking beam 4 away from the locking plate 1 and compress the elastic member 7. When the bottom of the locking plate 1 is higher than the top surface of the locking beam 4, the locking beam 4 is pushed under the locking plate 1 between the first platform 12 and the second platform 22 under the action of the elastic member 7. At this time, the hoist lowers the gate to complete the locking of the gate.

[0047] S2: AsFigures 8 to 12 As shown, when the gate needs to be unlocked, the hoist lifts the gate upward. The second arc surface 21 on the outer side of the unlocking plate 2 contacts the inclined surface 41 of the locking beam 4. The gate continues to be lifted, causing the locking beam 4 to move away from the unlocking plate 2 and compress the elastic member 7. Before the locking beam 4 disengages from the unlocking plate 2, if the hoist is operated to lower the gate, since the unlocking plate 2 is light and is under the compression of the elastic member 7 at this time, the locking beam 4 jams the unlocking plate 2 and moves upward. When the unlocking plate 2 contacts the locking plate 1, the first platform 12 and the second platform 22 are in contact, and the first arc surface 11 and the second arc surface 21 combine to form an arc surface. Under the action of the self-weight of the gate, the locking beam 4 can smoothly move from the unlocking plate 2 to the locking plate 1. Subsequently, the gate continues to be lowered, and the locking beam 4 slides along the first arc surface 11 of the locking plate 1 to the equilibrium state, completing the unlocking action of the gate.
