[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] According to the coal mine underground blocking device of the embodiment of the present invention, the coal mine underground blocking device includes a frame 1, a mesh grate 3, a partition baffle 2 and a traction mechanism, the frame 1 is arranged at the open channel, the mesh grate 3 is located at the bottom of the frame 1 and can move up and down relative to the frame 1, the partition baffle 2 is located on the frame 1 and the partition baffle 2 is located above the mesh grate 3, the partition baffle 2 can move up and down relative to the frame 1, the traction mechanism includes a winch 6, a wire rope 4 and a pulley, the pulley is arranged at the top of the frame 1, the first end of the wire rope 4 passes around the pulley and is detachably connected to the partition baffle 2 and the mesh grate 3 to drive the partition baffle 2 and the mesh grate 3 to rise, the second end of the wire rope 4 is connected to the winch 6, and the wire rope 4 is wound around the winch 6 as the winch 6 rotates. The frame 1 and the traction mechanism can drive the mesh grate 3 and the partition baffle 2 to move up and down relative to the open channel, avoiding the dilemma of the fixed mesh grate 3 being entangled with debris and difficult to clean. When there are too many debris on the mesh grate 3 to reduce the flow rate, the traction mechanism lowers the partition baffle 2, and the partition baffle 2 separates the open channel, and then the traction mechanism pulls the mesh grate 3 up, cleans and replaces the mesh grate 3, and then puts the mesh grate 3 back into the open channel. The traction mechanism pulls the partition baffle 2 up. At this time, the partition baffle 2 can achieve full shielding of the part above the water flow surface, reducing the wind loss, and continue the blocking operation. The cooperation of the winch 6 and the wire rope 4 realizes the remote control of the lifting and lowering of the mesh grate 3 and the partition baffle 2, reducing the labor intensity of the workers. The setting of the pulley makes the wire rope 4 evenly stressed during the traction process, extending the service life of the equipment. The mesh grate 3 and the partition baffle 2 should be selected according to the open channel section at the water tank entrance, and the mesh grate 3 and the partition baffle 2 with a processing width slightly smaller than the open channel width and a height slightly larger than the open channel depth. The winch 6 can be a small two-way locking manual winch 6.

[0020] The underground coal mine barrier device according to the embodiment of the present invention has the advantages of convenient cleaning and replacement of the grid grates and smooth water flow.

[0021] In some embodiments, the underground coal mine barrier device also includes a box, which is located at the bottom of the frame 1 and connected to the frame 1, the mesh grate 3 is slidably connected to the first side of the box, and the partition baffle 2 is slidably connected to the second side of the box.

[0022] Specifically, the box is arranged at the bottom of the frame 1 to improve the structural strength of the frame 1, and the box provides an installation position for the grid grate 3 and the partition baffle 2, which can better fix the grid grate 3 and the partition baffle 2, making cleaning and maintenance more convenient and improving work efficiency. The height of the box can be the same as that of the grid grate 3 and the partition baffle 2.

[0023] In some embodiments, a crossbeam is disposed on the top of the frame 1, and the pulley is arranged in the middle of the crossbeam.

[0024] Specifically, the arrangement of the crossbeam increases the load-bearing capacity of the frame 1 and ensures the stability of the equipment in complex environments. The pulley is located in the middle of the crossbeam, which makes the wire rope 4 more stable during the traction process and reduces the failure rate. The arrangement of the pulley makes it easier to pull the grid grate 3 or the partition baffle 2. Optionally, a pulley block is arranged in the middle of the crossbeam, and the wire rope 4 is wound around the pulley block to save more effort.

[0025] In some embodiments, the underground coal mine barrier device further includes a lifting ring 5, which is respectively arranged on the top of the mesh grate 3 and the partition baffle 2, and a lifting hook is provided at the first end of the wire rope 4, which is used to cooperate with the lifting ring 5.

[0026] Specifically, the operator can quickly hang the hook on the lifting ring 5, or remove the hook from the lifting ring 5, which improves the convenience and efficiency of the operation. It is convenient for the steel wire rope 4 to quickly connect and separate with the mesh grate 3 and the partition baffle 2, which improves the convenience of operation. The design of the lifting ring 5 allows the device to adapt to mesh grates 3 and partition baffles 2 of different sizes and shapes, improving the versatility and flexibility of the device.

[0027] In some embodiments, a locking member is also included, and the locking member is located on the hook to close the hook to prevent the hook from being separated from the lifting ring 5 during the lifting process.

[0028] Specifically, the use of the locking member ensures that the hook and the lifting ring 5 will not separate during the lifting process, thereby improving safety and preventing the hook from separating from the lifting ring 5 during the lifting process, thereby preventing the mesh grate 3 and the partition baffle 2 from impacting the open channel and causing damage.

[0029] In some embodiments, the locking member includes a spring and a blocking piece, wherein the blocking piece is pivotally connected to the hook, one end of the spring is connected to the hook, and the other end of the spring is connected to the blocking piece, and the spring pushes the blocking piece to close the opening of the hook.

[0030] Specifically, in order to ensure that the baffle can reliably close the opening of the hook, the baffle can be designed with a certain curvature to match the opening shape of the hook, increase the contact area, and improve the closing effect. At the same time, the elastic force of the spring should be adjusted according to the actual use situation to ensure that the baffle can be effectively pushed to close the opening under normal working conditions, but when it is necessary to hang or take the hanging object, the operator can easily overcome the elastic force to operate. The baffle should be made of high-strength, corrosion-resistant materials, such as stainless steel or alloy steel, to ensure its service life and stability in the harsh environment of coal mines. The spring should also be made of high-quality spring steel to ensure that its elastic force is long-lasting and stable.

[0031] Optionally, an automatic unlocking mechanism is also included. When the hook is connected to the lifting ring 5, the automatic unlocking mechanism can automatically release the blocking piece to facilitate the hanging operation; when the hook is separated from the lifting ring 5, the blocking piece is automatically locked to prevent the hook from accidentally opening. For example, an electric push rod can be set on the hook. When the lifting ring 5 enters the hook, the electric push rod retracts and unlocks the blocking piece to facilitate the lifting ring 5 to enter the hook. After the lifting ring 5 enters the hook, the electric push rod extends and pushes the blocking piece to close the hook. When the lifting ring 5 leaves the hook, the electric push rod retracts and unlocks the blocking piece to facilitate the lifting ring 5 to leave the hook.

[0032] In some embodiments, a guide is also included, and the guide is arranged on the box body to guide the grid grate 3 and the partition baffle 2 to move relative to the box body in the up and down directions.

[0033] Specifically, the setting of the guide makes the mesh grate 3 and the partition baffle 2 move more smoothly in the process of up and down, reduces the jamming phenomenon, and avoids the mesh grate 3 and the partition baffle 2 deviating from the correct position when falling and failing to completely achieve the partition and blocking effect on the open channel.

[0034] In some embodiments, the guide member has a guide groove, the width of which is adapted to the thickness of the mesh grate 3 and the partition baffle 2, and at least part of the edges of the mesh grate 3 and the partition baffle 2 enter the guide groove.

[0035] Specifically, the width of the guide groove should be greater than the thickness of the mesh grate 3 and the partition baffle 2 to ensure that both can move up and down smoothly in the guide groove. The guide groove can be designed in a "T" shape or a "U" shape to increase the stability and reliability of the guide. For example, some protrusions or grooves can be set at the bottom of the guide groove to match the edges of the mesh grate 3 and the partition baffle 2 to reduce shaking and deviation. The guide can be made of high-strength, corrosion-resistant materials, such as stainless steel or alloy steel, to ensure its service life and stability in the harsh environment of coal mines.

[0036] Optionally, in order to improve the stability of the guide member, support points can be set at multiple positions of the guide member, such as pulleys at both ends and the middle position of the guide groove, to ensure that the grid grate 3 and the partition baffle 2 move smoothly in the guide groove, reduce the difficulty of operation, and improve work efficiency.

[0037] Optionally, a lubricant, such as lubricating oil or grease, is provided in the guide groove to reduce friction between the grid grate 3 and the partition baffle 2 during movement and extend the life of the equipment. Lubricants can be added to the guide groove regularly to ensure that the guide groove is always in a good lubricated state.

[0038] In some embodiments, a cleaning mechanism is provided on the box body, and the cleaning mechanism includes a rotating shaft and a cleaning brush. A plurality of cleaning brushes are distributed on the rotating shaft. The cleaning brushes periodically abut against the mesh grate 3 as the rotating shaft rotates to clean the mesh grate 3. The rotating shaft is pivotally connected to the box body, and the motor is transmission-connected to the rotating shaft.

[0039] Specifically, the length of the rotating shaft is adapted to the width of the mesh grate 3, the length of the cleaning brush is sufficient to contact the mesh grate 3, and the cleaning mechanism can automatically clean the mesh grate 3 regularly to ensure that its surface is clean and improve the blocking effect. After the mesh grate 3 rises, the motor is started to drive the cleaning brush to clean the surface of the mesh grate 3, which can improve the surface quality of the mesh grate 3 and facilitate the blocking of debris.

[0040] In some embodiments, a position sensor is further included. The position sensor is arranged on the first side of the box body to detect the position of the grid grate 3, and the position sensor is electrically connected to the motor.

[0041] Specifically, the position sensor can be a photoelectric sensor or a proximity switch, which is installed on the first side of the box body to detect the position of the grid grate 3. The sensor should be installed in an appropriate position to ensure that the up and down movement position of the grid grate 3 can be accurately detected. The electrical connection between the position sensor and the motor realizes the automatic control of the cleaning mechanism, reduces manual intervention, and improves the convenience and efficiency of operation.

[0042] The position sensor is electrically connected to the motor to achieve automatic control. When the position sensor detects that the grid grate 3 rises to a certain position, the motor is automatically started to drive the cleaning mechanism to clean; when the grid grate 3 falls, the motor is automatically stopped. This automatic control function can reduce manual intervention and improve the convenience and efficiency of operation.

[0043] It can also include an alarm, which is electrically connected to the position sensor. When the position sensor detects an abnormal situation, such as a position sensor failure or an abnormal position of the grid grate 3, the alarm can send out an audible and visual alarm signal to remind the operator to handle it in time.
