Description

Technical Field

[0001] The invention relates to the technical field of water environment detection, in particular to a real-time water pollution sampling device for environmental engineering detection. Background Art

[0002] Environmental testing is to track changes in environmental quality and determine the level of environmental quality by testing the content and emissions of various substances that have an impact on humans and the environment, so as to provide a basis and guarantee for environmental management, pollution control and other work; with the progress of society and the development of science and technology, the level of industrial production has greatly improved, and at the same time, water pollution is also constantly increasing. In order to reduce water pollution, it is often necessary to test the water quality in designated areas. Water pollution will poison aquatic organisms and affect drinking water sources and scenic spots. Therefore, all regions now implement real-time monitoring of water quality.

[0003] Based on the above, the inventors have discovered that the existing real-time sampling device for water pollution used for environmental engineering detection has the following main deficiencies. For example, the existing water environment sampling device needs to sample a specific water depth when sampling, and in the process of lifting upward after sampling, upper water will enter the sampling device, thereby affecting the results of sampling at a specific water depth of the water environment. In addition, the sampling device is prone to shaking when lifted above the water surface, causing leakage of the sampled water. Summary of the invention

[0004] In view of the above problems, the present invention provides a real-time water pollution sampling device for environmental engineering detection.

[0005] In order to achieve the above object, the present invention is implemented by the following technical scheme: a real-time water pollution sampling device for environmental engineering detection, the structure of which includes a sampling body, a fixing rod, and a rope, the top of the sampling body is fixedly connected to the fixing rod by bolts, and the top of the fixing rod is connected to the rope; The sampling body includes a supporting baffle, a series rod, a sampling device, and a sampling container. The supporting baffles are provided with three, and the supporting baffles are fixed and supported by four series rods and bolts. The sampling device is clamped and fixed by the two supporting baffles at the upper end, and the sampling container is clamped and fixed by the two supporting baffles at the lower end; The sampling device includes a mounting frame, a transmission structure, a servo motor, a battery, a control module, and a wireless network module. The inner bottom end of the mounting frame is provided with a transmission structure, and the transmission structure is meshed and connected with the servo motor. The control module is arranged on the left end surface of the mounting frame, the wireless network module is located on the right side of the mounting frame, and the wireless network module is arranged above the control module. The transmission structure includes a transmission gear seat, a threaded rod, a top block, a piston, and a concave groove. The transmission gear seat is fixedly installed at the inner bottom end of the installation frame, and the threaded rod is threadedly matched with the transmission gear seat, and the bottom end surface of the threaded rod is fixedly connected to the top block. The piston is arranged on the end surface of the top block, and the side end surface of the piston is provided with three concave grooves; The transmission gear seat includes a support seat and a threaded tube. The support seat is fixedly mounted on the bottom end surface of the mounting frame. The threaded tube is clamped and mounted inside the support seat. The threaded tube is provided with threads inside the threaded tube to match the threads of the threaded rod. The side end of the threaded tube is provided with a gear to mesh with the servo motor. The sampling body is placed in the water through a rope, so that the servo motor and the gear can drive the threaded tube to rotate, and the threaded tube and the threaded rod can drive it to move upward, so that the piston can move upward against the inside of the sampling container, thereby extracting and storing deep water in the water environment. The battery can provide power, so that when the sampling body enters the water, the detection personnel can send a signal to the control module through the wireless network module to let the servo motor work to sample the water.

[0006] Furthermore, the sampling container is provided with a container tank, a through groove, and a flow stop device, the container tank is clamped and fixed by two supporting partitions, the through groove is arranged on the top end surface of the container tank, and the flow stop device is arranged on the bottom end surface of the container tank; By cooperating with the piston in the sampling container, water can be drawn through the flow-stop device for sampling.

[0007] Furthermore, the flow-stopping device is provided with a leak-proof ring, a support frame, and a float. The leak-proof ring is fixedly installed at the inner bottom end of the flow-stopping device, the support frame is fixedly connected to the inner top end of the flow-stopping device, and the float is clamped and installed on the end face of the support frame.

[0008] The piston moves upward in the container to generate negative pressure to absorb the float, so that the float can be stuck on the end surface of the support frame to allow the water flow to move upward for sampling. When the piston stops moving, the float will slide downward due to gravity and seal the leak-proof ring.

[0009] Furthermore, it is characterized in that: the leak-proof ring includes a leak-proof body, a recessed slot, and a through slot. The side end of the leak-proof body is provided with a recessed slot, and the recessed slot can be clamped on the bottom of the flow-stopping device for fixation, while the through slot is located inside the leak-proof body.

[0011] Furthermore, the support frame is supported by two legs, and the end surface of the support frame is in a circular ring shape; The float is supported by the circular ring-shaped end surface of the support frame, so that water can flow through the gap of the support frame.

[0012] Furthermore, the top of the through groove is provided with a slope with an inclination of 30 degrees.

[0013] By arranging a 30-degree inclined surface at the top of the through groove, the contact area between the leak-proof body and the floating ball can be increased to improve the sealing performance. Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes a servo motor drive method to allow a piston to move upward against the inside of a sampling container to generate negative pressure, thereby extracting water from an aquatic environment and allowing the water to enter the interior of a container tank for storage. Storing water in the container tank can prevent external moisture from entering the container tank again, thereby reducing the detection error of deep water in the aquatic environment.

[0015] When the container tank is filled with sampled water, the piston stops moving and the negative pressure in the container tank decreases, so that the float slides downward under the influence of gravity and then seals the leak-proof ring to prevent the water collected in the container tank from leaking out.

The transmission structure 132 is provided at the bottom of the mounting frame 131, and the transmission structure 132 is meshed and connected with the servo motor 133. The control module 135 is provided on the left end surface of the mounting frame 131, and the wireless network module is located on the right side of the mounting frame 131. The wireless network module 136 is provided above the control module 135. The transmission structure 132 includes a transmission gear seat 1321, a threaded rod 1322, a top block 1323, a piston 1324, and a recessed groove 1325. The transmission gear seat 1321 is fixedly installed at the inner bottom end of the installation frame 131, and the threaded rod 1322 is threadedly matched with the transmission gear seat 1321, and the bottom end surface of the threaded rod 1322 is fixedly connected with the top block 1323. The piston 1324 is arranged on the end surface of the top block 1323, and the side end surface of the piston 1324 is provided with three recessed grooves 1325; The transmission gear seat 1321 includes a support seat 221 and a threaded tube 222. The support seat 221 is fixedly mounted on the bottom end surface of the mounting frame 131. The threaded tube 222 is mounted inside the support seat 221. The threaded tube 222 has threads inside that are threadedly matched with the threaded rod 1322. The side end of the threaded tube 222 is provided with a gear 223 that is meshed and connected with the servo motor 133. The sampling body 1 is placed into the water through the rope 3, so that the servo motor 133 and the gear 223 can cooperate to drive the threaded tube 222 to rotate, and the threaded tube 222 and the threaded rod 1322 can cooperate to move upward, so that the piston 1324 can move upward against the inside of the sampling container 14, thereby extracting and storing deep water in the water environment, and the battery 134 can supply power, so that when the sampling body 1 enters the water, the detection personnel can send a signal to the control module 135 through the wireless network module 136 to let the servo motor 133 work to sample the water.

[0026] Based on the above embodiment, the specific working principle is as follows: the battery 134 can be used for power supply, so that when the sampling body 1 enters the water, the detection personnel can send a signal to the control module 135 through the wireless network module 136, so that the servo motor 133 works to sample the water. During the sampling process, the sampling body 1 is placed in the water using the rope 3, so that the servo motor 133 cooperates with the gear 223 to drive the threaded tube 222 to rotate, and the threaded tube 222 cooperates with the threaded rod 1322 to move upward, so that the piston 1324 can move upward against the inside of the sampling container 14 to generate negative pressure, thereby extracting water from the water environment and allowing the water to enter the container tank 141 for internal storage.

[0027] Example 2: Please refer to Figure 6-Figure 7 , the specific embodiments of the present invention are as follows: The sampling container 14 is provided with a container tank 141, a through groove 142, and a flow stop device 143. The container tank 141 is clamped and fixed by two supporting partitions 11. The through groove 142 is arranged on the top end surface of the container tank 141, and the flow stop device 143 is arranged on the bottom end surface of the container tank 141. By cooperating with the piston 1324 in the sampling container 14 , water can be drawn through the flow stop device 143 for sampling.

[0028] The flow-stopping device 143 is provided with a leak-proof ring 144, a support frame 145, and a floating ball 156. The leak-proof ring 144 is fixedly mounted on the inner bottom end of the flow-stopping device 143, the support frame 145 is fixedly connected to the inner top end of the flow-stopping device 143, and the floating ball 156 is clamped and mounted on the end surface of the support frame 145; The piston 1324 moves upward in the container tank 141 to generate negative pressure to absorb the float 156, so that the float 156 can be stuck on the end surface of the support frame 145 to allow the water flow to move upward for sampling. When the piston 1324 stops moving, the float 156 will slide downward due to the influence of gravity and then block the leak-proof ring 144.

[0029] The leak-proof ring 144 includes a leak-proof body 1441, a recessed slot 1442, and a through slot 1443. The side end of the leak-proof body 1441 is provided with a recessed slot 1442, and the recessed slot 1442 can be stuck on the bottom of the flow-stopping device 143 for fixing, while the through slot 1443 is located inside the leak-proof body 1441. The leak-proof body 1441 allows water to flow in the through groove 1443 , and the circular shape of the through groove 1443 cooperates with the float 156 to block the flow of water.

[0030] The support frame 145 is supported by two legs, and the end surface of the support frame 145 is in a circular ring shape.

[0032] The top of the through slot 1443 is provided with a slope with an inclination of 30 degrees.

[0033] By setting a 30-degree inclined surface at the top of the through groove 1443, the contact area between the leak-proof body 1441 and the floating ball 156 can be increased to improve the sealing performance. Based on the above embodiment, the specific working principle is as follows: by cooperating with the piston 1324 through the interior of the sampling container 14, water can be extracted through the flow stop device 143 for sampling, and then the piston 1324 moves upward in the container tank 141 to generate negative pressure to absorb the float 156, so that the float 156 can be stuck on the end surface of the support frame 145 to allow the water flow to move upward for sampling, and when the piston 1324 stops moving, the float 156 will slide downward due to the influence of gravity and then block the leak-proof ring 144 to prevent the water collected in the container tank 141 from leaking out.
