[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 5 The utility model provides a side wall support device for a water conservancy project construction channel, comprising a bottom plate 1; a plurality of electric push rods 11 are fixedly connected to the side wall of the bottom plate 1; the electric push rods 11 are evenly distributed on the side wall of the bottom plate 1 and have the same structure; a mounting plate 12 is fixedly connected to the end of the electric push rod 11; the mounting plate 12 and the bottom plate 1 are in sliding fit; a support plate 13 is hingedly connected to the side wall of the mounting plate 12; a bracket 14 is fixedly connected to the side wall of the mounting plate 12; a first screw 15 is threadedly connected to the side wall of the bracket 14 ; The first screw rod 15 passes through the wall of the bracket 14 and is threadedly connected thereto; a pair of push rods 16 are symmetrically hinged at the ends of the first screw rod 15; a pair of guide rails 17 are fixedly connected to the side walls of the mounting plate 12; the guide rails 17 are symmetrically arranged on both sides of the mounting plate 12 and have the same structure; a slider 18 is slidably connected to the inner side wall of the guide rail 17; the push rod 16 and the slider 18 are in an articulated relationship; a connecting arm 19 is hinged to the side wall of the slider 18; the connecting arm 19 is in an articulated relationship with the support plate 13; When in use, the staff puts the bottom plate 1 into the channel, and then holds and rotates the first screw 15. By rotating the first screw 15, the top rod 16 can push the slider 18 to slide in the guide rail 17. At this time, the sliding of the slider 18 can drive the connecting arm 19 to move, and a certain force is applied to the support plate 13 through the connecting arm 19, so that its angle can be adjusted. When the adjustment is completed, by starting the electric push rod 11, the electric push rod 11 can push the mounting plate 12 to move, so that the support plates 13 on both sides approach and press on the channel side walls, thereby supporting the channel side walls. In this process, the existing support device is usually fixed, which makes it inconvenient to adjust the angle it supports, thereby making it difficult to support the channel side walls with different inclination angles. At this time, the angle of the support plate 13 is adjusted by rotating the first screw 15, so that the support plate 13 plays a supporting role on the channel side walls with different inclination angles, thereby improving the practicality of the support plate 13.

[0027] Further, such as Figure 1 , Figure 2As shown, a plurality of universal wheels 2 are evenly fixed to the bottom of the bottom plate 1; a pair of fixing plates 21 are provided on the side walls of the bottom plate 1; the fixing plates 21 are symmetrically arranged on both sides of the bottom plate 1 and have the same structure; a second screw 22 is threadedly connected to the side wall of the fixing plate 21; the second screw 22 penetrates the wall of the fixing plate 21 and is threadedly connected thereto; an extrusion plate 23 is rotatably connected to the end of the second screw 22; a plurality of barbs 24 are evenly fixed to the side wall of the extrusion plate 23; when in use, the bottom plate 1 is pushed by a staff member to make the universal wheel 2 roll in the channel to adjust the position of the bottom plate 1, and when the adjustment is completed, the staff member The operator holds and rotates the second screw 22, and the second screw 22 can push the extrusion plate 23 down to make it close to the ground. At this time, the extrusion plate 23 applies pressure to the barb 24, which can make the barb 24 insert into the soil and fix the bottom plate 1 to reduce the rolling of the universal wheel 2. In this process, the bottom plate 1 can be reduced. Due to the certain weight of the bottom plate 1, it is inconvenient to move it, which makes the process of adjusting the position of the bottom plate 1 more cumbersome for the operator. At this time, the universal wheel 2 is set, which makes it convenient to move and adjust the bottom plate 1. At the same time, the barb 24 can fix the bottom plate 1 after the movement is completed.

[0028] Further, such as Figure 2 As shown, the side wall of the bottom plate 1 is provided with a pair of slide grooves 3; the slide grooves 3 are symmetrically arranged on both sides of the bottom plate 1 and have the same structure; the side wall of the slide groove 3 is slidably connected with an insert block 31; the side wall of the insert block 31 is fixedly connected with a rubber pad 32; the insert block 31 is fixedly connected to the fixed plate 21; the side wall of the bottom plate 1 is rotatably connected with a pair of first spring rods 33; the first spring rods 33 are symmetrically arranged on both sides of the bottom plate 1 and have the same structure; the end of the first spring rod 33 is fixedly connected with an insert rod 34; the side wall of the insert block 31 is provided with a slot 35; when in use, the staff holds the fixed plate 21 and inserts the insert block 31 into the slide groove 3. At this time, a certain friction force will be generated due to the contact between the rubber pad 32 and the slide groove 3, so that the insert block 31 is pre-fixed, and then The staff will hold and rotate the insertion rod 34, and when the insertion rod 34 is rotated to the position corresponding to the slot 35, by loosening the insertion rod 34, a certain reaction force will be applied under the elastic force of the first spring rod 33, so that the insertion rod 34 is inserted into the slot 35, and the insertion block 31 is fixed, thereby completing the installation of the fixing plate 21. In this process, the second screw rod 22 can be reduced to be inconvenient to disassemble and replace when rusted after long-term use, thereby increasing a certain amount of workload. At this time, the insertion block 31 is inserted into the slide groove 3 to fix it, thereby facilitating the disassembly and maintenance of the second screw 22. At the same time, the rubber pad 32 can play a pre-fixing role when fixing the insertion block 31, reducing the possibility of the insertion block 31 sliding out of the side wall of the slide groove 3.

[0029] Further, such as Figure 4 , Figure 5 As shown, the side wall of the guide rail 17 is symmetrically provided with a pair of through holes 4; the side wall of the slider 18 is fixedly connected with a pair of second spring rods 41; the second spring rods 41 are symmetrically arranged on both sides of the slider 18 and have the same structure; the end of the second spring rod 41 is fixedly connected with a scraper 42; when in use, when the slider 18 slides in the guide rail 17, the dirt attached to the inner wall of the guide rail 17 can be scraped off by the contact between the scraper 42 and the inner wall of the guide rail 17, and then pushed out to the outside through the through hole 4, and at the same time, the contact between the scraper 42 and the guide rail 17 will cause a certain amount of wear on the scraper 42, so that the distance between the two is increased, and at this time, the scraper 42 is pushed out to the outside through the through hole 4. The elastic force of the second spring rod 41 will push the scraper 42 so that the scraper 42 is in full contact with the inner wall of the guide rail 17. In this process, the guide rail 17 can be reduced to be easily attached to the inner wall after long-term use, which makes it difficult to clean it, thereby causing a certain impact on the sliding effect between the guide rail 17 and the slider 18. At this time, the scraper 42 is used to scrape off the dirt, thereby playing a cleaning role on the dirt attached to the guide rail 17, improving the smoothness of the sliding between the guide rail 17 and the slider 18. At the same time, the second spring rod 41 can increase the full contact between the scraper 42 and the guide rail 17, thereby improving the cleaning effect.

[0030] Further, such as Figure 5 As shown, a plurality of cleaning brushes 5 are evenly fixedly connected to the side wall of the scraper 42; a connecting rod 51 is fixedly connected to the side wall of the cleaning brush 5; the connecting rod 51 passes through the wall of the cleaning brush 5 and is fixedly connected thereto; when in use, while the scraper 42 is used to scrape off the dirt, the cleaning brush 5 can be used to clean the position after the scraper 42 has scraped off the remaining dirt, and in the process of cleaning by the cleaning brush 5, a plurality of cleaning brushes 5 can be fixedly connected by the connecting rod 51 so that they are concentrated together during cleaning. In this process, the poor cleaning effect of the scraper 42 can be reduced, resulting in some dirt still remaining on the inner wall of the guide rail 17 after the scraper 42 has scraped, which will have a certain impact on the sliding effect of the guide rail 17 and the slider 18. At this time, the cleaning brush 5 is provided to further increase the cleaning effect of the dirt attached to the inner wall of the guide rail 17, and the cleaning effect of the cleaning brush 5 during cleaning can be improved by the connecting rod 51.

[0031] Further, such as Figure 2As shown, a pair of blocks 6 are hinged on the side wall of the fixing plate 21; the blocks 6 are symmetrically arranged on both sides of the fixing plate 21 and have the same structure; a plurality of slots 61 are evenly opened on the side wall of the bottom plate 1; the blocks 6 correspond to the positions of the slots 61; when in use, the block 6 is first held and pulled by the staff, and when the block 6 is pulled open, the insertion block 31 is then fixed, and finally the block 6 corresponds to the position of the slot 61. At this time, the block 6 is released, and it will automatically reset under the action of the internal torsion spring at the hinge of the block 6, so that it is stuck in the side wall of the slot 61. In this process, it can reduce the risk of foreign objects accidentally pulling the insertion rod 34, causing the insertion rod 34 to easily slide out of the side wall of the slot 35, thereby affecting the fixing effect of the insertion block 31 to a certain extent. At this time, the block 6 is stuck in the side wall of the slot 61, thereby further increasing the fixing effect of the insertion block 31 in the slide groove 3.

[0032] Further, such as Figure 2 As shown, the side wall of the card block 6 is fixedly connected with a buckle plate 7; the buckle plate 7 is arranged in an arc shape; when in use, the staff puts the finger on the side wall of the buckle plate 7, and the finger can be hooked under the arc effect of the buckle plate 7, and then a certain force is applied to the buckle plate 7 to pull the card block 6 open. In this process, it can reduce the inconvenience of the staff in holding the card block 6, which makes it easy for the staff to slip off the side wall when pulling. At this time, the buckle plate 7 is set, which makes it convenient to pull the card block 6 open.

[0033] Working principle: When in use, the staff puts the bottom plate 1 into the channel, and then holds and rotates the first screw 15. By rotating the first screw 15, the top rod 16 can push the slider 18 to slide in the guide rail 17. At this time, the sliding of the slider 18 can drive the connecting arm 19 to move, and a certain force is applied to the support plate 13 through the connecting arm 19, so that its angle can be adjusted. When the adjustment is completed, the electric push rod 11 is started, and the electric push rod 11 can push the mounting plate 12 to move, so that the support plates 13 on both sides approach and press on the side walls of the channel, so as to support the side walls of the channel. When in use, the staff pushes the bottom plate 1 to make the universal wheel 2 roll in the channel to push the bottom plate 1 is adjusted. When the adjustment is completed, the staff holds and rotates the second screw rod 22, and the second screw rod 22 can push the extrusion plate 23 down to make it close to the ground. At this time, the extrusion plate 23 applies pressure to the barb 24, which can be inserted into the soil to fix the bottom plate 1 to reduce the rolling of the universal wheel 2. When in use, the staff holds the fixing plate 21 and inserts the plug block 31 into the slide groove 3. At this time, a certain friction force will be generated due to the contact between the rubber pad 32 and the slide groove 3, so as to pre-fix the plug block 31. Then, the staff holds and rotates the insertion rod 34. When the insertion rod 34 is rotated to the position corresponding to the slot 35, the insertion rod 34 is released under the elastic force of the first spring rod 33. The scraper 42 is pressed against the guide rail 17 to remove dirt from the guide rail 17, and the dirt is then removed from the guide rail 17 through the cleaning brush 5. The position scraped by the scraper 42 is cleaned to sweep away the remaining dirt, and during the cleaning process of the cleaning brush 5, multiple cleaning brushes 5 can be fixedly connected by the connecting rod 51 so that they can be concentrated together during cleaning. When in use, the staff first holds and pulls the block 6, and when the block 6 is pulled open, the plug block 31 is then fixed, and finally the block 6 will correspond to the position of the slot 61. At this time, the block 6 is released, and it will automatically reset under the action of the internal torsion spring at the hinge of the block 6, so that it is stuck in the side wall of the slot 61. When in use, the staff places their fingers on the side wall of the buckle plate 7, and the fingers can be hooked under the arc action of the buckle plate 7, and then a certain force is applied to the buckle plate 7 to pull the block 6 open.

[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.
