Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] See also Figure 1 - Figure 5The utility model provides a blocking and protective structure for water conservancy project construction, including a support plate 1; the support plate 1 is arranged in a pair; a first support tube 11 is fixedly connected to the end of the outer wall of the support plate 1; a fixing ring 12 is provided on the side wall of the first support tube 11; a shaking handle 13 is rotatably connected to the side wall of the fixing ring 12; the shaking handle 13 passes through the fixing ring 12; an oblique ring gear 14 is fixedly connected to the outer wall of the shaking handle 13; a square fixing plate 19 is fixedly connected to the inner side of the first support tube 11; the oblique ring gear 14 is rotatably connected to the square fixing plate 19; a first fixing column 15 is fixedly connected to the inner side wall of the first support tube 11; a first gear 16 is rotatably connected to the outer wall of the first fixing column 15; an L-shaped gear 17 is provided on the inner side of the first support tube 11; the L-shaped gear 17 is in contact with the first gear 16; a support block 18 is fixedly connected to the end of the outer wall of the L-shaped gear 17. When the equipment is working, the shaking handle 13 is turned to rotate the beveled ring gear 14, thereby driving the first gear 16 to rotate. At this time, the L-shaped gear 17 will move upward or downward, driving the support block 18 to move. By setting the first gear 16 and the L-shaped gear 17, when the staff installs the equipment, the overall height of the equipment can be adjusted, which is convenient for the equipment to be used in various situations, increasing the practicality and convenience of the equipment, and facilitating the staff to use the equipment. By setting the beveled ring gear 14, when the equipment is adjusted, the weight above will not cause the first gear 16 to reverse, thereby increasing the stability of the equipment and reducing the probability of equipment failure.

[0027] Further, such as Figure 3 and Figure 4 As shown, the outer wall of the first fixing column 15 is fixedly connected to the ratchet 2; the inner wall of the first supporting tube 11 is fixedly connected to the second fixing column 21; the outer wall of the second fixing column 21 is fixedly connected to the spring 22; the inner wall of the first supporting tube 11 is fixedly connected to the third fixing column 23; the outer wall of the third fixing column 23 is rotatably connected to the pawl 24; the outer wall of the pawl 24 is fixedly connected to the spring 22; the outer wall of the pawl 24 is fixedly connected to the sliding rod 25; the outer wall of the sliding rod 25 is fixedly connected to the extension column 26; the bottom of the outer wall of the extension column 26 is fixedly connected to a circular ring handle 27. When the equipment is working, the first fixed column 15 will rotate, thereby driving the ratchet 2 to rotate. When the height of the equipment rises, the ratchet 2 can rotate normally. When it stops rising, the pawl 24 prevents the ratchet 2 from rotating in the opposite direction. At this time, the ring handle 27 is pulled to disengage the pawl 24 from the ratchet 2. At this time, the ratchet 2 can rotate in the opposite direction. Through the set spring 22 and the pawl 24, the height of the equipment will not change when the height adjustment is completed. When the height needs to be lowered, the operation is simple, which increases the stability and convenience of the equipment and facilitates the use and maintenance of the equipment by the staff.

[0028] Further, such as Figure 5As shown, the first support tube 11 is fixedly connected to the outer wall of the first support tube 11 with a first fixing plate 3; the bottom of the outer wall of the first fixing plate 3 is fixedly connected to a threaded column 31; the bottom of the outer wall of the threaded column 31 is provided with a fourth fixing column 32; the threaded column 31 is threadedly connected to the fourth fixing column 32; a pair of second fixing plates 33 are fixedly connected to the bottom of the outer wall of the fourth fixing column 32; the inner wall of the second fixing plate 33 is rotatably connected to a conical wheel 34. Rotating the fourth fixing column 32 can adjust the distance between the threaded column 31 and the fourth fixing column 32, so that the conical wheel 34 moves toward the ground. When the equipment is used or the position of the equipment needs to be adjusted, the friction between the equipment and the ground becomes rolling friction through the fourth fixing column 32 and the threaded column 31, which is convenient for the staff to move the equipment. Through the conical wheel 34, the equipment can still move normally on muddy ground, reducing the probability of the equipment slipping.

[0029] Further, such as Figure 1 and Figure 5 As shown, the outer wall of the support block 18 is fixedly connected with a fifth fixing column 4; the fifth fixing column 4 is arranged in a mirror-symmetrical manner; the outer wall of the fifth fixing column 4 is fixedly connected with a U-shaped fixing plate 41; the inner wall of the U-shaped fixing plate 41 is provided with a fixing bolt 42; the fixing bolt 42 penetrates part of the U-shaped fixing plate 41; the outer wall of the fixing bolt 42 is provided with a flexible cloth 43; the flexible cloth 43 is penetrated by the fixing bolt 42. The combination of the fixing bolt 42 and the U-shaped fixing plate 41 allows the flexible cloth 43 to move with the height of the support block 18. The setting of the fixing bolt 42 makes it convenient and quick to replace the flexible cloth 43. If necessary, the flexible cloth 43 can be replaced with a hard material to meet the needs of the staff for the equipment and facilitate the use of the equipment by the staff.

[0030] Further, such as Figure 1 As shown, the side wall of the support plate 1 is provided with a plurality of extended ground nails 5; the extended ground nails 5 penetrate the support plate 1; the extended ground nails 5 are arranged around the first support tube 11, and the extended ground nails 5 do not contact the first support tube 11. When installing equipment, most of the equipment is on a dirt road surface. By setting the extended ground nails 5, the extended ground nails 5 are nailed into the ground to enhance the overall stability of the equipment, reduce the possibility of the equipment tipping over in an emergency, and increase the practicality of the equipment.

[0031] Further, such as Figure 2As shown, a pair of limiting columns 6 are fixedly connected to the inner side of the first support tube 11; the limiting columns 6 are arranged on both sides of the L-shaped gear 17; the limiting columns 6 are in sliding contact with the L-shaped gear 17; the length of the limiting columns 6 is greater than the length of the L-shaped gear 17. When the staff adjusts the equipment, the L-shaped gear 17 will slide up and down, and the setting of the limiting columns 6 prevents the L-shaped gear 17 from moving to both sides, reducing the possibility of the L-shaped gear 17 tilting when the equipment encounters a collision, increasing the practicality of the equipment, and reducing the failure rate of the equipment.

[0032] Further, such as Figure 4 As shown, the side wall of the first support tube 11 is provided with a plurality of balls 7; the balls 7 are in contact with the slide bar 25. When the device is working, the slide bar 25 will slide and rub against the first support tube 11. The balls 7 are provided to convert the sliding friction between the two into rolling friction, which is convenient for the staff to use the device and reduces the difficulty for the staff to use the device.

[0033] Working principle: When the equipment is working, the shaking handle 13 is turned to rotate the oblique ring gear 14, thereby driving the first gear 16 to rotate. At this time, the L-shaped gear 17 will move upward or downward, driving the support block 18 to move. Through the first gear 16 and the L-shaped gear 17, when the staff installs the equipment, the overall height of the equipment can be adjusted, which is convenient for the equipment to be used in various situations, increasing the practicality and convenience of the equipment, and facilitating the use of the equipment by the staff. Through the oblique ring gear 14, when the equipment is adjusted, the weight above will not cause the first gear 16 to reverse, which increases the stability of the equipment and reduces the probability of equipment failure. When the height of the equipment is adjusted, the first fixed column 15 will rotate, thereby driving the ratchet 2 to rotate. When the height of the equipment rises, the ratchet 2 can rotate normally. When the height stops rising, the pawl 24 prevents the ratchet 2 from rotating in the opposite direction. At this time, the ring handle 27 is pulled to disengage the pawl 24 from the ratchet 2. At this time, the ratchet 2 can rotate in the opposite direction. The spring 22 and the pawl 24 are arranged so that the height of the equipment will not change when the height adjustment is completed. When the height needs to be lowered, the operation is simple, which increases the stability and convenience of the equipment and facilitates the use and maintenance of the equipment by the staff. The distance between the threaded column 31 and the fourth fixed column 32 can be adjusted by rotating the fourth fixed column 32. The conical wheel 34 moves toward the ground. When the equipment is used or needs to be adjusted, the friction between the equipment and the ground becomes rolling friction through the fourth fixing column 32 and the threaded column 31, which is convenient for the staff to move the equipment. The conical wheel 34 is set so that the equipment can still move normally on muddy ground, reducing the probability of the equipment slipping. The combination of the fixing bolt 42 and the U-shaped fixing plate 41 allows the flexible cloth 43 to move with the height of the support block 18. The fixing bolt 42 is set so that the flexible cloth 43 can be replaced quickly and conveniently. If necessary, the flexible cloth 43 can be replaced with a hard material to meet the needs of the workers. The equipment is convenient for the staff to use. When installing the equipment, most of the equipment is on a dirt road. The extended ground nail 5 is set to nail the extended ground nail 5 into the ground to enhance the overall stability of the equipment, reduce the possibility of the equipment tipping over in case of an emergency, and increase the practicality of the equipment. When the staff adjusts the equipment, the L-shaped gear 17 will slide up and down. The limit column 6 is set to prevent the L-shaped gear 17 from moving to both sides, reducing the possibility of the L-shaped gear 17 tilting when the equipment encounters a collision, increasing the practicality of the equipment and reducing the failure rate of the equipment. When the equipment is working, the slide bar 25 will cause sliding friction with the first support tube 11. The ball 7 is set to turn the sliding friction between the two into rolling friction, which is convenient for the staff to use the equipment and reduces the difficulty of the staff to use the equipment.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
