DETAILED DESCRIPTION

[0020] The utility model will be further described in connection with the drawings:

[0021] Figure 1 And Figure 2 The self-locking device of the water slag filter water bin slag gate shown in the figure mainly comprises a rotary lock catch 4, a locking pin 5, a push rod 6, a pulley 7, a high position unlocking arc-shaped boss 9, and a low position locking arc-shaped boss 11, wherein the low position locking arc-shaped boss 11 and the high position unlocking arc-shaped boss 9 are arranged on the trolley 8 below the gate 1 and can move linearly back and forth, and the trolley 8 moves back and forth along a straight line parallel to the opening and closing direction of the gate 1 through a guide mechanism. The rotary lock catch 4 is hingedly connected to the side of one side gate 1 through a pin shaft, the rotation axis of the rotary lock catch 4 is perpendicular to the opening and closing direction of the gate 1, the locking pin 5 that cooperates with the rotary lock catch 4 is fixedly installed on the other side gate 1, one end of the push rod 6 is fixedly connected to the locking end of the rotary lock catch 4, and the bottom end of the rotary lock catch 4 and the push rod 6 is provided with the pulley 7, and the two pulleys 7 are in sliding contact with the low position locking arc-shaped boss 11 and the high position unlocking arc-shaped boss 9 respectively and realize the locking and unlocking functions of the rotary lock catch 4 and the locking pin 5 on the top plane.

[0022] The rotary lock catch 4 is a double-arm lock catch structure, comprising a locking arm 4-1 and a driving arm 4-2, the locking arm 4-1 and the driving arm 4-2 are integrated, the included angle between the locking arm 4-1 and the driving arm 4-2 is obtuse, and the pin shaft is connected to the connection position of the locking arm 4-1 and the driving arm 4-2; the locking arm 4-1 cooperates with the locking pin 5, when the lock catch is in the locked state, the locking arm 4-1 can tightly cooperate with the locking pin 5, forming a firm locking effect; the free end of the driving arm 4-2 is connected with the pulley 7, which not only reduces the friction during operation, but also improves the smoothness and efficiency of operation. In some possible embodiments, an opening groove can be formed on the locking arm 4-1, which is matched with the locking pin 5, so that the locking arm 4-1 can tightly cooperate with the locking pin 5, when the lock catch is in the locked state, the locking arm 4-1 is tightly embedded with the locking pin through the opening groove, forming a firm locking effect, effectively preventing accidental unlocking or loosening. In other embodiments, the locking end of the locking arm 4-1 can be designed as a hook structure. The push rod 6 and the driving arm 4-2 form a splayed structure, which not only enhances the overall stability of the lock catch, but also optimizes the mechanical transmission efficiency of the push rod 6 during the driving of the lock catch, making the lock catch more smooth and labor-saving when opening and closing.

[0023] Preferably, a reset mechanism is arranged on the same side of the rotary lock 4 as the door 1, which is used to reset the rotary lock 4 to the locked position where the locking pin 5 is buckled. It can ensure that the door quickly returns to the locked state after the slagging or water filtering operation is completed, effectively preventing the problem of the door not being correctly locked due to negligence or error. The reset mechanism of the embodiment includes a spring 3 and a spring mounting seat 2. The spring mounting seat 2 is fixed to the door 1 on the same side of the rotary lock 4 and above the rotary lock 4. The two ends of the spring 3 are connected to the spring mounting seat 2 and the locking arm 4-1 of the rotary lock 4, respectively.

[0024] The trolley 2 is mainly composed of a supporting plate, side plates and running wheels. The supporting plate serves as the bearing base, and the side plates are fixedly installed on both sides of the supporting plate to enhance the structural strength and stability of the trolley 2. The running wheels arranged at the bottom of the supporting plate enable the trolley 2 to move on a designated track or ground. In order to realize the linear reciprocating motion of the trolley 2, a guide mechanism is connected to the trolley 2, and the core component of the guide mechanism is a power machine, which is responsible for providing the driving force required for the motion of the trolley 2. In the embodiment, the power machine adopts a hydraulic cylinder 12, which has the characteristics of high power density, easy control and smooth operation, and is very suitable for driving the linear motion of the trolley 2. The trolley 2 is particularly provided with a slag discharge hole 10, which is located in the slagging area of the door 1. When the door 1 is opened for slagging operation, the waste slag or waste water can be smoothly discharged through the slag discharge hole 10, thereby ensuring the normal operation and cleanliness of the trolley 2 and the system in which it is located.

[0025] The low-position locking arc-shaped boss 11 and the high-position unlocking arc-shaped boss 9 on the trolley 2 are arranged at intervals along the moving direction of the trolley 2, and the interval distance is the horizontal distance between the locked position and the unlocked position, and their positions correspond to the positions of the pulleys to ensure that the locking and unlocking actions can be triggered, respectively. When the pulley 7 at the bottom end of the rotary lock 4 contacts the low-position locking arc-shaped boss 11 and slides to the top end plane thereof, the rotary lock 4 is in the locked position where the locking pin is buckled. When the pulley 7 at the bottom end of the push rod 6 contacts the high-position locking arc-shaped boss 9 and slides to the top end plane thereof, the rotary lock 4 is in the unlocked position where it is completely separated from the locking pin 5.

[0026] When the door 1 needs to be opened for slagging, the hydraulic cylinder 12 is started, and the trolley 2 moves in the unlocking direction. The high-position unlocking arc-shaped boss 9 moves towards the direction close to the push rod 6. When the pulley 7 at the bottom end of the push rod 6 contacts the high-position unlocking arc-shaped boss 9 and slides to the top end plane thereof, the push rod 6 pushes the driving arm 4-2, so that the rotary lock 4 is separated from the locking pin 5, and the automatic unlocking of the door 1 is realized, as shown in Figure 2 The door 1 is opened, and the water slag falls from the opening of the door 1 and is discharged through the slag discharge hole 10 of the trolley 2.

[0027] After the slag is discharged, when the gate 1 needs to be closed and locked, the hydraulic cylinder 12 drives the trolley 2 to move in the locking direction. The low-position locking arc-shaped boss 11 moves towards the direction close to the rotating lock catch 4. When the pulley 7 at the bottom end of the rotating lock catch 4 contacts and slides to the top end plane of the low-position locking arc-shaped boss 11, the rotating lock catch 4 rotates under the action of the reset mechanism spring 3, the locking arm 4-1 is tightly buckled with the locking pin 5, and the automatic locking of the gate is realized. See Figure 1 After the gate 1 is closed, the water slag is filtered in the water slag filter bin, and the filtered water is discharged through the gap of the gate 1. After the gate 1 is closed, the spring 3 of the reset mechanism pulls the rotating lock catch 4 back to the locking position, ensuring that the gate 1 is always in the locked state in the closed state, preventing water slag leakage.

[0028] The self-locking device of the water slag filter bin slag gate has the advantages of simple structure, easy manufacturing, installation and maintenance, low cost, automatic locking and unlocking of the gate through mechanical locking, automatic rebound and mechanical limiting function, reducing labor input and improving work efficiency; the locking reliability is high, which can effectively prevent the gate from being accidentally opened due to water slag pressure, ensuring the stability of the equipment operation; at the same time, the device eliminates the safety hidden danger caused by manual operation, significantly improves the efficiency and reliability of the equipment operation, and reduces the labor cost and safety hidden danger.
