[0002] The traditional method of locking the gate when opening by manually moving the locking beam has the following defects:

[0003] 1. It is easy to produce deviations, resulting in incomplete cooperation with the locking plate, posing a safety hazard.

[0004] 2. As the orifice increases and the weight of the gate increases, the weight of the locking beam will increase, and manual handling will be extremely laborious.

[0006] In order to solve the above problems, people invented a self-locking device to replace the traditional locking beam. The patent with publication number CN106368179A discloses a labor-saving manual locking beam for power station steel gate maintenance, which can save manpower and reduce risks.

When the driving device rises to a first height along with the gate, the locking beam is driven to move to a first position along a first direction by driving the transmission device.

[0010] When the driving device descends from the first height to the second height along with the gate, the locking beam maintains the first position and locks the gate;

[0038] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 10 As shown, the present invention provides a novel gate locking beam structure, including a locking beam 8, a transmission device 2 and a driving device.

[0040] The locking beam 8 is installed on the left and right sides of the gate groove pier 13 and can move back and forth along a straight line to achieve locking and unlocking of the gate 1. To this end, a pair of parallel tracks 3 are installed on the left and right sides of the gate groove pier 13, and rollers 11 are installed at both ends of the locking beam 8. The rollers 11 and the tracks 3 are used to roll together to achieve the movable installation of the locking beam 8.

[0041] The transmission device 2 is fixedly mounted on the left and right sides of the gate slot pier 13 and is connected to the locking beam 8 in a one-to-one correspondence. The driving device is fixedly mounted on the gate 1 and rises and falls with the gate 1. The driving device can form a transmission connection with the transmission device 2 during the process of the gate 1 rising and falling, thereby driving the locking beam 8 to move.

[0042] As a preferred example, the transmission device 2 includes a feed chain mechanism 4 , a feed gear 6 , a reverse chain mechanism 5 and a reverse gear 7 .

[0043] The driving device includes a feed rack 9 and a retract rack 10. The feed rack 9 can mesh with the inner part of the feed gear 6 to drive the feed chain mechanism 4 to drive the locking beam 8 to move in the first direction when rising. The retract rack 10 can mesh with the outer part of the retract gear 7 to drive the retract chain mechanism 5 to drive the locking beam 8 to move in the second direction when descending.

[0044] The feed chain mechanism 4 and the reverse chain mechanism 5 are both chain mechanisms with the same structure and transmission ratio, and their chains are both connected to the locking beam 8. Similarly, the feed gear 6 and the reverse gear 7 are gears with the same structure. The difference is that the feed gear 6 is installed on the rotating shaft of the feed chain mechanism 4 through a one-way bearing, and the reverse gear 7 is installed on the rotating shaft of the reverse chain mechanism 5 through a one-way bearing. Due to the one-way transmission effect of the one-way gear, the feed gear 6 drives the feed chain mechanism 4 to rotate forward only when rotating forward, thereby driving the locking beam 8 to move along the first direction. The reverse gear 7 drives the reverse chain mechanism 5 to reverse only when rotating reversely, thereby driving the locking beam 8 to move along the second direction. The first direction is the feed direction of the locking beam 8, that is, the direction of moving close to the gate 1, and the second direction is the reverse direction of the locking beam 8, that is, the direction of moving away from the gate 1. When setting the moving direction of the locking beam 8, it can be parallel to the water retaining surface of the gate 1.

[0045] It should be noted that the module and number of teeth of the rack and the gear are determined according to the actual moving distance of the locking beam 8. This is a conventional method and will not be described in detail.

[0046] As a preferred example, the gate 1 has locking plates 1.2 on both sides thereof, and below the locking plates 1.2 is an avoidance groove 1.1, which is convenient for the locking beam 8 to enter and support the locking plates 1.2.

[0047] like Figure 8 As shown, when the gate needs to be opened, the gate 1 is lifted by the hoist at the top. During the lifting process, the feed rack 9 first meshes with the feed gear 6, thereby driving the feed chain mechanism 4 to rotate forward. At this time, the locking beam 8 moves along the first direction driven by the chain. When the gate 1 rises to the first height, the locking beam 8 moves to the first position. At this time, the locking plate 1.2 on the gate 1 is just above the locking beam 8.

[0048] like Fig. 9 As shown, the gate 1 reaches the first height and then descends. During this process, the feed gear 6 does not drive the feed chain mechanism 4 to react, so the locking beam 8 does not move. When the gate 1 descends to the second height, the locking plate 1.2 just contacts the locking beam 8, and the gate 1 is locked at this position.

[0049] like Fig.10 As shown, when the gate needs to be closed, the gate 1 is lifted again by the hoist. During the lifting process, the feed rack 9 will be separated from the feed gear 6, and the retracting rack 10 will be engaged with the retracting gear 7, thereby driving the retracting chain mechanism 5 to rotate forward. At this time, the locking beam 8 moves along the second direction driven by the chain. When the gate 1 rises to the third height, the locking beam 8 moves to the second position, and the gate 1 is unlocked at this position. Then the gate 1 is lowered to the bottom of the groove. Due to the effect of the one-way bearing, the feed chain mechanism 4 and the retracting feed chain 5 will not be driven to rotate during the descent of the gate 1, so that the locking beam 8 remains stationary. It should be noted that if the second position is the initial position of the locking beam 8, the number of teeth of the retracting rack 10 should be large, so as to meet the requirement of driving the locking beam 8 to retreat. If the second position is not the initial position of the locking beam 8, the number of teeth of the retracting rack 10 should be small. The locking beam 8 can be moved from the second position to the initial position by gravity, that is, the track 3 is inclined, and the slope is 1:200-1:100, preferably 1:110. The height of the locking beam 8 in the first position is greater than its height in the second position. In this way, when the locking beam 8 retreats to the second position, although it is no longer driven by the retreat chain mechanism, it can return to the initial position under the action of gravity.

[0050] As a preferred example, in order to enable the gate 1 to be locked at different heights, thereby controlling the water flow, three locking plates 1.2 are provided in the vertical direction, and three feed racks 9 and three retracting racks 10 are also provided on each side of the gate 1. Obviously, the matching process of the feed racks 9 and retracting racks 10 at each height on the gate 1 and the feed gear 6 and the retracting gear 7 is the same, thereby realizing the locking of the gate 1 at different heights.

[0051] As a preferred example, the feed chain mechanism 4 and the feed rack 9 are both located on the front side of the gate 1 , and the retract chain mechanism 5 and the retract rack 10 are both located on the back side of the gate 1 .

[0052] As a preferred example, buffer devices 14 are provided on both sides of the gate channel pier 13. When the locking beam 8 moves to the initial position, the buffer device 14 provides buffering for the locking beam 8.

[0053] It should be noted that after the gate 1 is closed, the feed rack 9 and the retract rack 10 are immersed in water, so in order to improve corrosion resistance, the racks and gears can be made of stainless steel or aluminum alloy.

[0054] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0055] It should be noted that the above specific implementation methods are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified and replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
