[0029] By adopting the above technical solution, the arc-shaped plate 11 can save material and installation space when protecting the water pump 2, thus reducing manufacturing costs.
[0030] Please refer to Figure 1 and Figure 2 The mounting component 13 includes: a base plate 131, on which an arc-shaped plate 11 and a water pump 2 are disposed; at least two support members 132, each support member 132 being disposed at the bottom of the base plate 131, and the support members 132 being spaced apart along the width direction of the base plate 131, each support member 132 being used to connect to a bracket at the tail end of the machine; and at least two mounting plates 133, each mounting plate 133 being disposed at the bottom of the base plate 131, and the mounting plates 133 being spaced apart along the width direction of the base plate 131, wherein... Figure 2 The direction of the middle arrow A is the width direction of the base plate 131. Each mounting plate 133 is provided with mounting holes 134, which are connected to the bracket at the tail of the machine through each mounting hole 134. The mounting plates 133 and the support members 132 are spaced apart along the length direction of the base plate 131.
[0031] By adopting the above technical solution and through the design of the mounting plate 133, when it is necessary to install the protective component 1 on the coal mining machine body, it can be installed by passing the fixing component through the mounting hole, which is convenient to operate and easy to disassemble and assemble.
[0032] Please refer to Figure 1 and Figure 3 The protective mechanism of the water pump in the coal mining face also includes a tilting assembly 3, which includes: a first guide plate 31, which is connected to the arc plate 11 and is located outside the arc plate 11; a threaded hole is provided on the first guide plate 31; a first screw 32, which is threadedly connected to the threaded hole on the first guide plate 31, and is rotatably mounted on the base plate 131 along the height direction of the base plate 131, and protrudes from the bottom of the base plate 131; and a second screw 33, which is rotatably mounted on the first screw 32, and extends along the extension direction of the first screw 32, and the second screw 33 has the same diameter and pitch as the first screw 32.
[0033] By adopting the above technical solution, and through the design of the first screw 32 and the second screw 33, when the water pump 2 needs to be repaired, the arc plate 11 is moved from the first screw 32 to the second screw 33, and the second screw 33 is rotated to remove the entire arc plate 11 from the water pump 2, thereby allowing the water pump 2 to be repaired.
[0034] Please refer to Figure 2 The protective mechanism of the water pump in the coal mining face also includes a second guide plate 34 and a guide rod 35. The second guide plate 34 is installed on the arc plate 11. The second guide plate 34 and the first guide plate 31 are spaced apart along the edge of the arc plate 11. The second guide plate 34 is slidably sleeved on the guide rod 35 along the height direction of the bottom plate 131. The guide rod 35 extends along the height direction of the bottom plate 131 and is installed on the bottom plate 131.
[0035] By adopting the above technical solution and through the design of the guide rod 35, the stability of the arc plate 11 can be increased and the arc plate 11 can be limited by the cooperation of the second guide plate 34 and the guide rod 35 during the movement of the arc plate 11.
[0036] The guide rod 35 is slightly longer than the first screw 32, and most preferably, the guide rod 35 is 10 cm longer than the first screw 32.

[0038] By adopting the above technical solution and through the design of the drive component 4, during the movement of the arc plate 11, the active bevel gear 42 and the driven bevel gear 41 can be driven to rotate by the hand-held part 43, thereby driving the arc plate 11 to move up and down. There is no need for manual lifting of the arc plate 11 for maintenance, saving the workers' physical strength.
[0039] Please refer to Figure 3 The protective mechanism of the water pump in the coal mining face also includes a limiting component 5, which includes: a limiting rod 51, one end of which slidably passes through the second screw 33 and is inserted into the first screw 32; and a gripping part 52, which is arranged along the extension direction of the limiting rod 51 and is connected to the end of the limiting rod 51 away from the first screw 32.
[0040] By adopting the above technical solution and through the design of the limiting rod 51, when the arc plate 11 needs to be moved onto the second screw 33, the limiting rod 51 passes through the second screw 33 and is inserted into the first screw 32, so that the coaxial lines of the second screw 33 and the first screw 32 coincide, which facilitates the up and down movement of the arc plate 11.
[0041] Working principle:
[0042] First, when the water pump 2 needs to be repaired, the hand-held part 43 is rotated to drive the active bevel gear 42 and the driven bevel gear 41 to rotate, thereby driving the arc plate 11 to move upward. When the arc plate 11 moves onto the second screw 33, the arc plate 11 disengages from the guide rod 35. At this time, the limiting rod 51 is pulled to disengage from the first screw 32. Then the second screw 33 is rotated, and the second screw 33 drives the arc plate 11 to rotate. At this time, the arc plate 11 is no longer covered outside the water pump 2, and then the water pump 2 is repaired.
