Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of water quality detection equipment, and particularly relates to a water environment detection device. BACKGROUND

[0002] At present, when the environmental detection department detects water quality, water samples at different depths need to be collected in rivers and lakes. The existing sampling equipment is too simple, generally being a sampling bottle tied on a line and thrown into the water for sampling. It is difficult to accurately control the sampling depth, and when sampling different depth water layers, multiple operations are required, which is low in work efficiency.

[0003] The existing Chinese patent application with the publication number CN117517004B discloses a water quality detection layered sampling device, which comprises a connecting assembly, a connecting frame provided with a plurality of connecting assemblies, a sampling box provided with a plurality of connecting assemblies, and a sealing plate. The sampling box is hollow inside and the bottom surface is through. The sealing plate seals the sampling box. A plurality of limiting pieces are connected to the connecting assembly, and the plurality of limiting pieces are used to control the rotation of one of the sampling boxes. After the rotation of the sampling box is completed, the sampling box is located below the connecting frame and the sealing plate seals the sampling box. The control assembly controls the rotation of the sampling box by controlling the limiting piece. The present application can facilitate the determination of the content of silt, facilitate sampling, and improve the accuracy of the device sampling.

[0004] However, the layered sampling device has the following defects in specific use:

[0005] 1. The existing layered sampling device samples different depths by setting sampling boxes at different heights. However, the sampling device controls the sampling box to rotate in sequence for sampling by the control assembly controlling the limiting piece. The control assembly can only control one sampling box for sampling at the same time, and cannot realize the synchronous sampling of multiple sampling boxes. The sampling time is long and the efficiency is low. The samples collected at different times may affect the data and the accuracy of subsequent sample data analysis.

[0006] 2. The existing layered sampling device uses a splicing method to install the sampling box. The sampling depth is related to the number of connecting frames. Although the number of sampling boxes can be flexibly adjusted, the collection of deep water samples is not flexible enough. The user needs to install multiple connecting frames to extend the overall length of the device, which is complex to operate and low in flexibility. SUMMARY

DETAILED DESCRIPTION

[0063] ​​The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0064] Example: A water environment monitoring device

[0065] like Figures 1-12 As shown, a water environment monitoring device has the following specific structure:

[0066] The system comprises a base plate 10, a primary telescopic assembly 20, a transmission assembly 30, a secondary telescopic assembly 40, and sampling bottles 50. The primary telescopic assembly 20 is located at the front of the base plate 10. A mounting plate 101 is fixedly installed on the upper rear of the base plate 10. The secondary telescopic assembly 40 is mounted in transmission cooperation with the primary telescopic assembly 20 via the transmission assembly 30. Several sampling bottles 50 are detachably mounted on the front of the secondary telescopic assembly 40. The primary telescopic assembly 20 includes: a primary moving plate 201, which is slidably mounted on the front of the base plate 10, and whose rear end is slidably engaged with the front end of the base plate 10; and a first slider 202, which has a groove 102 on one side of the front of the base plate 10, the bottom of which penetrates the base plate 10. A mounting plate 101 is fixedly installed on the rear of the primary moving plate 201. A first slider 202, which is slidably engaged with the slide groove 102, can limit the movement of the primary moving plate 201 by cooperating with the slide groove 102, thereby improving the stability of the primary moving plate 201 during its vertical movement. An electric actuator 203, which is waterproof, is fixedly installed on the other side of the front of the base plate 10. The electric actuator 203 can drive the primary moving plate 201 to move vertically along the base plate 10. A connecting block 204 is fixedly installed on the movable end of the telescopic rod of the electric actuator 203. One end of the connecting block 204 is fixedly connected to the bottom of the opposite side of the primary moving plate 201. A secondary telescopic assembly 40 is provided in front of the primary moving plate 201. The secondary telescopic assembly 40 slides relative to the primary moving plate 201 under the drive of the transmission assembly 30.

[0067] The working principle is as follows: when water sampling is performed, the device can be fixed on a ship body or a buoy through the mounting plate 101, and the device is vertically extended into water for operation. Then the movable rod of the electric push rod 203 is extended through the controller, the electric push rod 203 drives the primary moving plate 201 to move to a deeper water level through the connecting block 204 connected with the electric push rod 203, so that the sampling bottle 50 is moved to a deeper place for sampling through the movement of the primary moving plate 201; the primary moving plate 201 can drive the secondary telescopic assembly 40 to move downward along the primary moving plate 201 through the transmission assembly 30 while moving, and the primary moving plate 201 and the secondary telescopic assembly 40 can further increase the stroke of the device through mutual cooperation, so that the device can sample at a deeper place and expand the sampling range of the device; the primary moving plate 201 and the secondary telescopic assembly 40 can limit the sampling bottle 50 underwater, prevent the sampling bottle 50 from moving under the impact of water flow, improve the stability of the sampling bottle 50, keep a plurality of sampling bottles 50 stably at a fixed water level during sampling, improve the accuracy of layered sampling of the device, and realize synchronous sampling of different water levels.

[0068] With reference to Figure 4 , Figure 10 The secondary telescopic assembly 40 comprises: a secondary moving plate 401, which is slidingly and fitly installed on one side of the front of the primary moving plate 201; a slide rail 402, which is fixedly installed on one side of the front of the primary moving plate 201 close to the electric push rod 203, and both ends of the slide rail 402 are open; and a second sliding block 403, which is slidingly and fitly installed in the slide rail 402, and the front of the second sliding block 403 is fixedly connected with the rear of the secondary moving plate 401. The secondary moving plate 401 moves under the driving of the transmission assembly 30.

[0069] During water sampling, the primary moving plate 201 moves downward, and the transmission assembly 30 drives the secondary moving plate 401 to move, the secondary moving plate 401 further moves downward along the primary moving plate 201, which greatly improves the sampling depth of the device, and the second sliding block 403 and the slide rail 402 cooperate to limit the secondary moving plate 401, thereby improving the stability of the secondary moving plate 401 during movement.

[0070] With reference to Figure 5 , Figure 9The transmission assembly 30 includes: a rotating shaft 301, which is fixedly installed on the upper and lower parts of the front of the primary moving plate 201, and the two rotating shafts 301 are symmetrically arranged in front of the primary moving plate 201; a synchronous pulley 302, which is bearing-mounted on the upper part of the rotating shaft 301; a synchronous belt 303, which drives the two synchronous pulleys 302; a fixed frame 304, which is fixedly installed on the front of the base plate 10 near the primary moving plate 201, and the lower part of one side of the synchronous belt 303 is fixedly connected to the side opposite to the fixed frame 304; and a fixed clamping plate 305, which is fixedly installed on the upper part of the other side of the synchronous belt 303, and one side of the fixed clamping plate 305 is fixedly connected to the side opposite to the secondary moving plate 401.

[0071] When the device is in use, as the primary moving plate 201 moves downward, the rotating shaft 301 in front of the primary moving plate 201 drives the synchronous wheel 302 to move synchronously. At this time, due to the limiting effect of the fixed frame 304 and the fixed clamping plate 305 on the synchronous belt 303, the primary moving plate 201 moves downward relative to the fixed frame 304. Conversely, the fixed frame 304 moves upward relative to the primary moving plate 201, driving the left side of the synchronous belt 303 connected to it to move. At this time, the synchronous belt 303 can be regarded as rotating clockwise. Then, the fixed clamping plate 305 installed on the right side of the synchronous belt 303 can drive the secondary moving plate 401 to move downward, realizing the extension of the secondary moving plate 401. Through this structural design, the stroke of the sampling bottle 50 installed in front of the secondary moving plate 401 can be doubled, realizing the sampling operation of deeper water levels.

[0072] For details, please refer to the following: Figure 2 , Figure 11 The front of the secondary moving plate 401 is fixedly equipped with several evenly distributed fixing blocks 60 from top to bottom. Each fixing block 60 has a T-shaped limiting groove 601 with an open top surface. A T-shaped locking block 602, which mates with the T-shaped limiting groove 601, is fixedly installed on the upper rear part of the sampling bottle 50. The T-shaped locking block 602 is vertically inserted into the T-shaped limiting groove 601 and slides within it. The T-shaped locking block 602 is engaged with the corresponding fixing block 60 via a limiting component 70. The fixing blocks 60 on the front of the secondary moving plate 401 facilitate the installation and removal of the sampling bottle 50. In use, the sampling bottle 50 is installed by inserting the T-shaped locking block 602 from top to bottom into the corresponding T-shaped limiting groove 601. The structure is simple and easy to operate. The limiting component 70 prevents the T-shaped locking block 602 from detaching from the T-shaped limiting groove 601, further improving the stability of the device.
