[0035] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 9 As shown, a self-propelled gate locking device is provided. When used, the present invention requires installation of one set on each side of the gate 1. Based on the structural characteristics of the gate 1 and the door slot, the present invention is arranged on the left and right sides of the gate 1. The present invention comprises a slide 3, a lock tongue 4, a connecting rod 5, a slide bar 6, an upper tapered locking block 7, a lower tapered locking block 8, and a spring 9.

[0037] The slide 3 is fixedly mounted on the gate groove on one side of the gate 1. It is made of multiple sets of steel plates of different specifications, with a sliding channel formed in the center. The bottom plate of the slide 3 is connected to the I-beam 2 embedded in the top of the gate groove by welding or bolting. A connecting plate 10 is also provided between the slide 3 and the I-beam 2. Obviously, the I-beam 2 can also be replaced by a locking beam. For the traditional method of fixing the gate with a locking beam, the slide 3 can be installed on the locking beam. A rear plate 3.1 is protruding from the rear of the slide 3 to form a reserved space, which is convenient for installing the spring 9 and reserving the shrinkage margin of the spring 9.

[0038] The lock tongue 4 is slidably mounted within the sliding channel of the slide 3, enabling linear horizontal movement. The lock tongue 4 is also made of steel plates of varying specifications, with a wedge-shaped structure 4.1 at its front end. The inclined surface of the wedge-shaped structure 4.1 is positioned below the horizontal plane, providing a sliding engagement with the lock block.

[0039] The connecting rod 5 is vertically arranged on the left and right sides of the gate 1. For the existing gate 1, both sides thereof are provided with support plates 1.2 for locking beam support, so the connecting rod 5 is directly vertically mounted on the support plates 1.2 to form a connection with the gate 1.

[0040] Sliding rod 6 is coaxially mounted on the top of connecting rod 5, allowing it to rise and fall with gate 1. The bottom of sliding rod 6 features a boss with a threaded hole for connection and positioning. Based on the specifications of gate 1, both connecting rod 5 and sliding rod 6 are made of steel, with a design diameter range of 40 to 80 mm.

[0041] The upper conical locking block 7 is fixedly arranged on the top of the slide rod 6 with the bottom surface facing downward. Specifically, a threaded hole is provided on the bottom surface of the upper conical locking block 7, and an external thread is provided on the top of the slide rod 6. The upper conical locking block 7 is fixed to the top of the slide rod 6 through a threaded connection.

[0042] Lower conical locking block 8 is slidably mounted on slide rod 6 below upper conical locking block, with its bottom surface facing upward. Specifically, a through hole is centrally located in lower conical locking block 8, which is slidably connected to the shaft of slide rod 6. Lower conical locking block 8 and upper conical locking block 7 have essentially the same appearance, differing only in that upper conical locking block 7 has a circular top surface, while lower conical locking block 8 has a flat top surface.

[0043] The spring 9 abuts against the lock tongue 4 and the slide 3 to drive the lock tongue 4 to move to the initial position.

[0044] To adjust the fixed height of gate 1 each time it is opened, a connecting rod 5 is preferably provided on gate 1 in an adjustable manner. Specifically, connecting rod 5 has multiple external threads and is connected to support plate 1.2 on gate 1 via two locking nuts 13 mounted on the external threads, thereby securing gate 1 and connecting rod 5 in different positions. When support plate 1.2 is connected to connecting rod 5 at a lower position, the gate 1's opening height is lowered, and the operating stroke of the gate hoist is correspondingly reduced.

[0045] In order to better form a sliding fit with the upper conical locking block 7 and the lower conical locking block 8 and realize the smooth movement of the moving parts, the front end of the lock tongue 4 is provided with an arcuate matching surface. The arcuate matching surface can match with the conical surface and the transition surface or connecting line between the conical surface and the bottom surface.

[0046] To prevent the lock tongue 4 from moving forward and out of the slide 3, a stopper 11 is provided at the rear end of the lock tongue 4. When the lock tongue 4 moves to its initial position, the stopper 11 contacts the slide 3 and forms a stopper. Specifically, the stopper 11 is a bolt with a size of M12-M20. A threaded hole is machined on the top surface of the lock tongue 4 near the rear end, and the stopper 11 is installed in the threaded hole. A stopper groove 3.2 is provided at the rear end of the slide 3 corresponding to the position of the stopper 11. When the stopper 11 enters the stopper groove 3.2, the lock tongue 4 is stopped, and the rear end of the lock tongue 4 is completely inserted into the slide 3.

[0047] In order to prevent the connecting rod 5 from bending due to unilateral force after locking the gate 1, a support 12 is provided on the gate 1. The top of the support 12 supports the inner part of the bottom surface of the upper conical locking block 7, so that both sides of the upper conical locking block 7 are supported.

[0048] The working principle and process of this utility model

[0049] In the closed state, the gate 1 is located at the lowest point of the gate slot and is in the initial position, and the gate 1 plays the role of blocking the water flow. When it is necessary to open the gate, the gate hoist is started, and the gate hoist lifts the gate 1 through the traction piece connected to the gate 1 lifting ear 1.1. When the gate 1 gradually rises from the initial position to the first position, the conical surface of the upper conical locking block 7 forms a sliding fit with the front end of the lock tongue 4, and as the upper conical locking block 7 rises, the lock tongue 4 is driven to retreat until the bottom surface of the upper conical locking block 7 exceeds the lock tongue 4. Since there is a gap between the upper conical locking block 7 and the lower conical locking block 8, the lock tongue 4 extends forward to the gap between the two and returns to the initial position of the lock tongue 4. Figure 2 and 3 As shown, at this time, the hoist is controlled to reverse, the bottom surface of the upper conical locking block 7 contacts the top surface of the lock tongue 4 and is supported by it and cannot fall, and then the hoist is controlled to pause, and the gate 1 is locked at the current height, that is, in the locked position.

[0050] When closing the gate, you need to unlock gate 1 first. Figures 4 to 7 As shown, when the gate hoist is started again to lift the gate 1 from the locked position to the second position, the edge of the lower conical locking block 8 drives the lock tongue 4 to retreat and after its bottom surface exceeds the lock tongue 4, the lock tongue 4 extends forward under the action of the spring 9. In this process, the front end of the lock tongue 4 drives the lower conical locking block 8 to rise until it contacts the bottom surface of the upper conical locking block 7.

[0051] like Figure 8 and 9As shown, the hoist is controlled to reverse, driving gate 1 downward. As gate 1 descends from the second position to the initial position, the edges of the upper and lower conical locking blocks 7 and 8 respectively drive the locking tongue 4 backward. After the bottom surface of the lower conical locking block 8 drops below the locking tongue 4, it falls back to its initial position under the action of gravity. After the bottom surface of the upper conical locking block 7 drops below the locking tongue 4, the locking tongue 4 extends forward to its initial position. After gate 1 reaches the initial position, the hoist is turned off, and gate closing is complete.

[0052] Obviously, during the process of opening and closing the gate, the locking operation of gate 1 cleverly utilizes the self-driving force of gate 1 when rising and falling to drive the lock tongue 4 to move, thereby realizing automatic locking and unlocking. This process does not rely on any external mechanical devices or equipment, and does not require major changes to the entire gate 1 facility. It is helpful to carry out renovations on the basis of existing gate 1 facilities and has high application value.
