In the environmental quality testing of construction projects, water quality sampling is an indispensable part. By sampling and testing the water quality in the construction area and surrounding waters, pollution sources can be discovered and controlled in a timely manner to prevent them from causing damage to surrounding water resources.

[0003] The patent with announcement number CN112595552B discloses a water quality sampling device for environmental engineering detection, which relates to the field of environmental engineering detection. In view of the problem that the existing water quality detection sampling device cannot sample water quality at different depths, and cannot block and clean impurities inside the water body during the sampling process, resulting in low sampling efficiency, the following scheme is proposed, which includes a suspension mechanism and a sampling mechanism, a traction rope is connected between the suspension mechanism and the sampling mechanism, and the suspension mechanism includes two symmetrically distributed mounting plates, a winding roller is rotatably installed between the two mounting plates, and the traction rope is wound around the circumferential side wall of the winding roller.

Moreover, these aquatic plants will also adhere to the surface of the sampling bucket, covering the sampling port of the sampling bucket, resulting in poor water flow during the sampling process, and even blocking the sampling port, affecting the sampling efficiency.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The mobile construction engineering environmental quality detection device described in the present invention utilizes a gathering and pushing mechanism. When there are many aquatic plants on the water surface and the water surface of the area to be sampled is covered, the push plate can be driven to move horizontally on the water surface to push the aquatic plants and move them away from the area below the sampling bucket. At the same time, the position of the push plate can be adjusted to more accurately push the aquatic plants away according to the position of the aquatic plants and actual needs, thereby providing a lowerable area for the sampling bucket, and there are no aquatic plants in this area, and then the push plate can be driven to move horizontally on the water surface to push the aquatic plants away from the area below the sampling bucket. The sampling bucket enters the water to perform sampling work, which can avoid the situation that aquatic plants adhere to the surface of the sampling bucket when the sampling bucket enters the water, thereby covering the sampling port of the sampling bucket, resulting in poor water flow during the sampling process, or even blocking the sampling port, affecting the sampling efficiency. In addition, when the push plate pushes the aquatic plants, the polymer plates on both sides can be driven to reciprocate in different directions at the same time. When the polymer plate rotates toward the inside of the push plate, the aquatic plants on the inside of the push plate will be squeezed to compress the volume of the aquatic plants and gather them in the middle of the push plate. The invention can avoid the overflow of aquatic plants from the edges of both sides of the push plate when the push plate pushes the aquatic plants, thereby ensuring the pushing effect and removing the aquatic plants on the water surface in the area below the sampling bucket more thoroughly. Moreover, after the push plate completes a pushing action, the scraper bar is driven to descend, and the scraper bar scrapes against the inner surface of the push plate, thereby removing the aquatic plants attached to the inner side of the push plate. At the same time, the angles of the two polymer plates can be adjusted so that the contact surfaces of the two polymer plates with the aquatic plants are flush with the edge of one side of the scraper bar, so that the scraper bar can remove the aquatic plants attached to the inner side of the push plate and the surface of the polymer plate at the same time. At the same time, the blade can be driven to descend so that it contacts the upper surface of the push plate to cut off the aquatic plants entangled on the push plate, thereby avoiding the situation that the scraper bar cannot scrape off the aquatic plants entangled on the surface of the push plate, thereby realizing the self-cleaning of the residual aquatic plants on the surface of the push plate and the polymer plate, thereby avoiding the situation that the aquatic plants attached to the surface of the push plate and the polymer plate fall to other positions on the water surface again during the subsequent pushing action, thereby eliminating the redundant pushing action and providing convenience for the subsequent pushing action.

[0021] 2. The mobile construction engineering environmental quality detection device described in the present invention can drive the threaded cylinder 1 to rotate through the motor 2 when the aquatic plants on the water surface below the sampling barrel are pushed away by the push plate, so that the threaded rod 2 drives the cover body to descend, and the telescopic rod 2 extends to make the cover body contact with the water surface. When the sampling barrel enters the water, the cover body can form a barrier around the sampling barrel, thereby preventing the aquatic plants from floating onto the sampling barrel again due to the flow of water. When the sampling barrel rises, the aquatic plants cover the surface of the sampling barrel again, which affects the subsequent use of the sampling barrel, further ensuring the subsequent use effect of the sampling barrel.

[0022] 3. The mobile construction engineering environmental quality detection device described in the present invention can be used by a staff member holding the handle and using the universal wheel to move the base. When the base moves to the specified position, the threaded rod is manually rotated to drive the fastening plate to descend, and the teeth at the bottom of the fastening plate are used to insert it into the soil, so that the base can be connected to the ground, ensuring the stable sampling work.

[0045] Specifically, a construction project refers to an engineering entity formed by constructing various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. These buildings and facilities are designed to meet people's needs for production, residence, study, public activities, etc. Construction projects may generate various types of pollution during the construction process, such as noise pollution, air pollution, water pollution, etc. By testing the environmental quality, these pollution sources can be discovered and controlled in a timely manner to prevent them from causing adverse effects on the surrounding environment, thereby ensuring the quality and safety of the project. In the environmental quality testing of construction projects, water quality sampling is an indispensable part. By sampling and testing the water quality in the construction area and surrounding waters, it can be discovered and controlled in a timely manner. Pollution sources are prevented from causing damage to surrounding water resources; when the existing water quality sampling device is used, the traction rope 46 is unwound to allow the sampling bucket 10 to enter the water. When the sampling bucket 10 descends to the water quality area to be tested, the cover of the sampling bucket 10 is driven to open, and water flows into the sampling bucket 10 through the sampling port to complete the sampling work. However, when there are many algae and floating aquatic plants on the water surface of the water quality area to be tested, the sampling bucket 10 will contact these aquatic plants when entering the water, and these aquatic plants will also adhere to the surface of the sampling bucket 10, covering the sampling port of the sampling bucket 10, resulting in poor water flow during the sampling process, and even blocking the sampling port, affecting the sampling efficiency;

[0046] Therefore, in order to solve the above problems, when the present embodiment is used, the universal wheel 3 is used to move the base 1 to the shore of the water area to be detected, and then according to the sampling position required, the motor 9 is started to drive the threaded rod 430 to rotate, so that the adjustment column 8 slides in the inner cavity of the frame 7, and the position of the sampling bucket 10 can be adjusted to be above the area to be sampled, and then the motor 8 48 is used to drive the rotating roller 17 to rotate, so that the traction rope 46 drives the sampling bucket 10 into the water, and when the sampling bucket 10 descends to the depth required for sampling, the solenoid valve on the water inlet 47 is opened, so that water flows into the sampling bucket 10 through the water inlet 47, and then the sampling bucket 10 is moved out of the water, and then the sample can be obtained by opening the drain port 45 at the bottom of the sampling bucket 10;

[0047] When there are more aquatic plants on the water surface and the water surface of the area to be sampled is covered, before the sampling barrel 10 is lowered, the motor 3 20 can be used to drive the threaded barrel 22 to rotate, so that the threaded rod 3 23 moves in the inner cavity of the threaded barrel 22, and the telescopic rod 1 21 is extended to make the push plate 28 contact with the water surface and gather the aquatic plants on the inner side of the push plate 28. Then, the motor 4 25 can be used to drive the connecting rod 1 26 and the connecting rod 27 to rotate, so that the push plate 28 can be moved horizontally to push the aquatic plants away from the bottom of the sampling barrel 10. At the same time, the motor 5 can be used to 31 drives the gear 32 to rotate, so that the gear ring 12 rotates, and the position of the push plate 28 is adjusted, so that the aquatic plants can be pushed away more accurately according to the position of the aquatic plants and actual needs, and an area is provided for the sampling bucket 10 to be lowered, and there are no aquatic plants in this area, and then the sampling bucket 10 is driven into the water to perform sampling work, which can avoid the aquatic plants adhering to the surface of the sampling bucket 10 when the sampling bucket 10 enters the water, thereby covering the sampling port of the sampling bucket 10, resulting in poor water flow during the sampling process, or even blocking the sampling port, affecting the sampling efficiency;

[0048] When the aquatic plants on the water surface below the sampling barrel 10 are pushed away, the motor 2 13 can drive the threaded cylinder 14 to rotate, so that the threaded rod 2 15 drives the cover 16 to descend, and the telescopic rod 2 29 is extended to make the cover 16 contact the water surface. When the sampling barrel 10 enters the water, the cover 16 can form a fence around the sampling barrel 10, avoiding the aquatic plants from floating onto the sampling barrel 10 again due to the flow of water. When the sampling barrel 10 rises, the aquatic plants cover the surface of the sampling barrel 10 again, which affects the subsequent use of the sampling barrel 10, further ensuring the subsequent use effect of the sampling barrel 10.

[0049] When the push plate 28 pushes the aquatic plants, the aquatic plants may overflow from the edges on both sides of the push plate 28. This may be due to the external force applied by the push plate 28 to the aquatic plants, causing the aquatic plants to flow, or because the push plate 28 pushes too many aquatic plants at a time, causing accumulation. When the above situation occurs, it will affect the pushing effect on the aquatic plants, and the removal of the aquatic plants will not be thorough. Therefore, when the push plate 28 pushes the aquatic plants, the motors 7 43 on both sides are started at the same time, and drive the aggregation plate 44 to rotate reciprocatingly. When the aggregation plate 44 rotates toward the inside of the push plate 28, the aquatic plants on the inside of the push plate 28 will be squeezed to compress the volume of the aquatic plants and gather them in the middle of the push plate 28; thereby avoiding the situation that the aquatic plants overflow from the edges on both sides of the push plate 28 when the push plate 28 pushes the aquatic plants, ensuring the pushing effect, and allowing the aquatic plants on the water surface in the area below the sampling bucket 10 to be more thoroughly removed;

[0050] When the push plate 28 completes a pushing action, its inner surface may be attached with aquatic plants, and even the aquatic plants may be entangled on the surface of the push plate 28. During the subsequent pushing action, these aquatic plants attached to the surface of the push plate 28 may fall to other positions on the water surface, and need to be pushed again, which is more troublesome. Therefore, when the push plate 28 completes a pushing action, the push plate 28 is away from the area below the sampling barrel 10, and the blade 36 is aligned with the upper surface of the push plate 28. The edge of the scraper 34 is flush with the inner surface of the push plate 28. The electric push rod 41 and the motor 38 can be started at the same time. The electric push rod 41 drives the scraper 34 to descend, and the scraper 34 scrapes against the inner surface of the push plate 28, so that the aquatic plants attached to the inner side of the push plate 28 can be removed. At the same time, the two focusing The angle of the closing plate 44 makes the contact surface of the two polymer plates 44 and the aquatic plants flush with the edge of one side of the scraper strip 34, so that the scraper strip 34 can remove the aquatic plants attached to the inner side of the push plate 28 and the surface of the polymer plate 44 at the same time. At the same time, the motor 6 38 drives the threaded cylinder 3 39 to rotate, so that the blade plate 35 descends, and the blade 36 contacts the upper surface of the push plate 28 to cut off the aquatic plants wrapped around the push plate 28, so as to avoid the situation that the scraper strip 34 cannot scrape off the aquatic plants wrapped around the surface of the push plate 28, thereby realizing the self-cleaning of the residual aquatic plants on the surface of the push plate 28 and the polymer plate 44, and avoiding the situation that the aquatic plants attached to the push plate 28 and the surface of the polymer plate 44 fall to other positions on the water surface again during the subsequent pushing action, which provides convenience for the subsequent pushing action;

[0051] Therefore, by utilizing the gathering and pushing away mechanism, when there are more aquatic plants on the water surface and the water surface of the area to be sampled is covered, the push plate 28 can be driven to move horizontally on the water surface to push the aquatic plants and move them away from the area below the sampling barrel 10. At the same time, the position of the push plate 28 can be adjusted to more accurately push away the aquatic plants according to the position of the aquatic plants and actual needs, thereby providing an area for the sampling barrel 10 to be lowered and free of aquatic plants. Then, the sampling barrel 10 can be driven into the water for sampling, thereby avoiding the sampling barrel 10 from being in the water. When entering the water, the aquatic plants adhere to the surface of the sampling barrel 10, thereby covering the sampling port of the sampling barrel 10, resulting in poor water flow during the sampling process, and even blocking the sampling port, affecting the sampling efficiency. In addition, when the push plate 28 pushes the aquatic plants, the polymer plates 44 on both sides can be driven to reciprocate in different directions at the same time. When the polymer plate 44 rotates toward the inside of the push plate 28, the aquatic plants on the inside of the push plate 28 will be squeezed to compress the volume of the aquatic plants and gather them in the middle of the push plate 28, thereby avoiding the aquatic plants from being pushed by the push plate 28. The situation that plants overflow from the edges of both sides of the push plate 28 ensures the pushing effect, so that the aquatic plants on the water surface in the area below the sampling bucket 10 can be removed more thoroughly. Moreover, when the push plate 28 completes a pushing action, the scraper bar 34 is driven to descend, and the scraper bar 34 scrapes against the inner surface of the push plate 28, so that the aquatic plants attached to the inner side of the push plate 28 can be removed. At the same time, the angles of the two polymer plates 44 can be adjusted so that the contact surfaces of the two polymer plates 44 and the aquatic plants are flush with the edge of one side of the scraper bar 34, so that the scraper bar 34 can simultaneously scrape the inner side of the push plate 28 and the surface of the polymer plate 44. The attached aquatic plants can be removed. At the same time, the blade 36 can be driven down to contact the upper surface of the push plate 28 to cut off the aquatic plants wrapped around the push plate 28, thereby avoiding the situation where the scraper 34 cannot scrape off the aquatic plants wrapped around the surface of the push plate 28, thereby achieving self-cleaning of the residual aquatic plants on the surfaces of the push plate 28 and the polymer plate 44, avoiding the situation where the aquatic plants attached to the surfaces of the push plate 28 and the polymer plate 44 fall again to other positions on the water surface during subsequent pushing actions, eliminating unnecessary pushing actions and providing convenience for subsequent pushing actions.

[0052] In this embodiment, Figure 1 As shown, a handle 2 is fixedly connected to the right side of the upper end surface of the base 1, and a threaded rod 4 is threadedly connected to both the front and rear sides of the base 1. A fastening plate 5 is rotatably provided at the lower end of the threaded rod 4, and a sliding rod 6 is fixedly connected to the right side of the upper end surface of the fastening plate 5, and the sliding rod 6 is slidably connected to the base 1.

[0053] Specifically, the staff holds the handle 2 and uses the universal wheel 3 to move the base 1. When the base 1 moves to the specified position, the threaded rod 4 is manually rotated to drive the fastening plate 5 to descend. The teeth at the bottom of the fastening plate 5 are used to insert it into the soil, so that the base 1 can be connected to the ground, ensuring the stable progress of the sampling work.

[0054] Working principle: the staff can move the base 1 by holding the handle 2 and using the universal wheel 3. When the base 1 moves to the specified position, the threaded rod 4 is manually rotated to drive the fastening plate 5 to descend, and the teeth at the bottom of the fastening plate 5 are used to insert it into the soil, so that the base 1 can be connected with the ground, ensuring the stable sampling work. According to the sampling position required, the motor 9 is started to drive the threaded rod 430 to rotate, so that the adjusting column 8 slides in the inner cavity of the frame 7, and the position of the sampling bucket 10 can be adjusted to be above the area to be sampled, and then the motor 8 48 is used to drive the rotating roller 17 to rotate, so that the traction rope 46 drives the sampling bucket 10 into the water. When After the sampling barrel 10 descends to the depth required for sampling, the solenoid valve on the water inlet 47 is opened to allow water to flow into the sampling barrel 10 through the water inlet 47, and then the sampling barrel 10 is removed from the water, and the sample can be obtained by opening the drain port 45 at the bottom of the sampling barrel 10; and when there are more aquatic plants on the water surface and the water surface of the area to be sampled is covered, before the sampling barrel 10 descends, the motor three 20 can be used to drive the threaded barrel two 22 to rotate, so that the threaded rod three 23 moves in the inner cavity of the threaded barrel two 22, and the telescopic rod one 21 is extended to make the push plate 28 contact with the water surface, and the aquatic plants are gathered on the inner side of the push plate 28, and then the motor four 25 is used to drive the connecting rod one 26 and The connecting rod 27 rotates to make the push plate 28 move laterally to push away the aquatic plants and remove them from the bottom of the sampling barrel 10. At the same time, the motor 31 can be used to drive the gear 32 to rotate, so that the ring gear 12 rotates and the position of the push plate 28 is adjusted. The aquatic plants can be pushed away more accurately according to the position of the aquatic plants and actual needs, providing a lowering area for the sampling barrel 10, and there are no aquatic plants in this area. Then, the sampling barrel 10 is driven into the water to perform sampling work, which can avoid the aquatic plants adhering to the surface of the sampling barrel 10 when the sampling barrel 10 enters the water, thereby covering the sampling port of the sampling barrel 10, resulting in sampling errors. The water flow is not smooth during the process, and the sampling port is even blocked, which affects the sampling efficiency; when the aquatic plants on the water surface below the sampling barrel 10 are pushed away, the motor 2 13 can drive the threaded cylinder 14 to rotate, so that the threaded rod 2 15 drives the cover 16 to descend, and the telescopic rod 29 is extended to make the cover 16 contact with the water surface. When the sampling barrel 10 enters the water, the cover 16 can form a barrier around the sampling barrel 10, avoiding the aquatic plants from floating onto the sampling barrel 10 again due to the flow of water. When the sampling barrel 10 rises, the aquatic plants cover the surface of the sampling barrel 10 again, which affects the subsequent use of the sampling barrel 10, further ensuring the subsequent use effect of the sampling barrel 10;When the push plate 28 pushes the aquatic plants, the aquatic plants may overflow from the edges of both sides of the push plate 28. This may be due to the external force exerted by the push plate 28 on the aquatic plants, causing the aquatic plants to flow, or because the push plate 28 pushes too many aquatic plants at a time, causing accumulation. When the above situation occurs, it will affect the pushing effect on the aquatic plants, and the removal of the aquatic plants is not complete. Therefore, when the push plate 28 pushes the aquatic plants, the motors 43 on both sides are started at the same time, and drive the polymer plate 44 to reciprocate. When the polymer plate 44 rotates toward the inside of the push plate 28, the aquatic plants on the inside of the push plate 28 will be pushed out. The plants are squeezed to compress the volume of the aquatic plants and gather them in the middle of the push plate 28; thereby avoiding the situation that the aquatic plants overflow from the edges of the two sides of the push plate 28 when the push plate 28 pushes the aquatic plants, ensuring the pushing effect, so that the aquatic plants on the water surface in the area below the sampling bucket 10 can be removed more thoroughly; and when the push plate 28 completes a pushing action, its inner surface may be attached with aquatic plants, and even the aquatic plants may be entangled on the surface of the push plate 28. In the subsequent pushing action, these aquatic plants attached to the surface of the push plate 28 may fall to other positions on the water surface, and need to be pushed again. Therefore, when the push plate 28 completes a pushing action, the push plate 28 is away from the area below the sampling barrel 10, and the blade 36 is aligned with the upper surface of the push plate 28. The edge of the scraper 34 is flush with the inner surface of the push plate 28. The electric push rod 41 and the motor 38 can be started at the same time, and the electric push rod 41 drives the scraper 34 to descend, and the scraper 34 and the inner surface of the push plate 28 form a scraping, so that the aquatic plants attached to the inner side of the push plate 28 can be removed. At the same time, the angles of the two polymer plates 44 can be adjusted so that the contact surface of the two polymer plates 44 with the aquatic plants is flush with the edge of one side of the scraper 34, so that the scraper 34 can simultaneously push the push plate 28. At the same time, the motor 6 38 drives the threaded cylinder 39 to rotate, so that the blade plate 35 descends, and the blade 36 contacts the upper surface of the push plate 28 to cut off the aquatic plants wrapped around the push plate 28, so as to avoid the situation that the scraper 34 cannot scrape off the aquatic plants wrapped around the push plate 28, thereby realizing the self-cleaning of the residual aquatic plants on the push plate 28 and the surface of the polymer plate 44, and avoiding the situation that the aquatic plants attached to the push plate 28 and the surface of the polymer plate 44 fall to other positions on the water surface again during the subsequent pushing action, which provides convenience for the subsequent pushing action. ;
