Description

Technical Field

[0001] The invention mainly relates to the technical field of water quality detection equipment, and specifically to a water environment detection device. Background Art

[0002] At present, when environmental monitoring departments test water quality, they need to collect water samples at different depths in rivers and lakes. The existing sampling equipment is too simple. Generally, sampling is carried out by tying a sampling bottle to a rope and throwing it into the water. It is difficult to accurately control the sampling depth, and when sampling water layers at different depths, multiple operations are required, resulting in low work efficiency.

[0003] The existing Chinese patent application with publication number CN117517004B discloses a stratified sampling device for water quality detection, which includes a connecting assembly; a connecting frame, which is provided with multiple and connected to the connecting assembly; a sampling box, which is provided with multiple and respectively rotatably connected to the inner wall of a connecting frame, and the sampling box is arranged above the connecting frame in the vertical direction, the interior of the sampling box is hollow, and the bottom surface of the sampling box is arranged through; a sealing plate, the sealing plate closes the sampling box; a limiting member, which is provided with multiple and connected to the connecting assembly, and the multiple limiting members are respectively used to control the rotation of one of the sampling boxes, and the sampling box is located below the connecting frame and the sealing plate closes the sampling box after the rotation is completed; a control assembly, the control assembly rotates the sampling box by controlling the limiting member, wherein, after the rotation of one of the sampling boxes is completed, the control assembly controls the rotation of the sampling box of the upper level of the sampling box. The present invention can facilitate the determination of sediment content, facilitate sampling, and improve the accuracy of sampling of the device.

[0004] However, the stratified sampling device has the following defects when used specifically: 1. When the existing stratified sampling device is sampling, sampling at different depths is performed by setting sampling boxes at different heights. However, when the sampling device is sampling, the control component controls the sampling boxes to rotate in sequence for sampling by controlling the limiter. The control component can only control one sampling box for sampling at the same time, and it is impossible to achieve synchronous sampling of multiple sampling boxes. The sampling time is long and the efficiency is low. The samples collected at different times may have a certain impact on the data, affecting the accuracy of subsequent sample data analysis.

[0005] 2. The existing stratified sampling device uses a splicing method to install the sampling box. The sampling depth is related to the number of connection frames. Although the number of sampling boxes can be flexibly adjusted, it is not flexible enough for collecting samples in deep water areas. The user needs to install multiple connection frames to extend the overall length of the device. The operation is complicated and the flexibility is low. Summary of the invention

[0021] Embodiment: A water environment detection device like Figure 1-12 As shown, a water environment detection device, the specific structure of which includes: A base plate 10, a primary telescopic component 20, a transmission component 30, a secondary telescopic component 40, and a sampling bottle 50. The base plate 10 is provided with a primary telescopic component 20 in front, and a mounting plate 101 is fixedly installed on the upper part of the rear of the base plate 10. The front of the primary telescopic component 20 is equipped with a secondary telescopic component 40 through the transmission component 30. A plurality of sampling bottles 50 are detachably installed on the front of the secondary telescopic component 40. The primary telescopic component 20 includes: a primary moving plate 201, a primary moving plate 201 is slidably installed in front of the base plate 10, and the rear of the primary moving plate 201 is slidably matched with the front of the base plate 10; a first slider 202, a slide groove 102 is opened on one side of the front of the base plate 10, and the bottom of the slide groove 102 passes through the base plate 10. A positioning plate 201 is fixedly installed on the rear of the primary moving plate 201. The first slider 202 is in the slide groove 102 and slidably cooperates with it. Through the mutual cooperation between the first slider 202 and the slide groove 102, the primary movable plate 201 can be limited, thereby improving the stability of the primary movable plate 201 during the up and down movement; the electric push rod 203, the electric push rod 203 is a waterproof electric push rod, and the electric push rod 203 is fixedly installed on the other side of the front of the base plate 10, and the electric push rod 203 can drive the primary movable plate 201 to move vertically along the base plate 10; the connecting block 204, the movable end of the telescopic rod of the electric push rod 203 is fixedly installed with a connecting block 204, and one end of the connecting block 204 is fixedly connected to the bottom of the opposite side of the primary movable plate 201; a secondary telescopic assembly 40 is provided in front of the primary movable plate 201, and the secondary telescopic assembly 40 slides relative to the primary movable plate 201 under the drive of the transmission assembly 30. The above working principle: when sampling water source, the device can be fixed on the hull or buoy through the mounting plate 101, and the device can be vertically extended into the water for operation. Afterwards, the controller is used to extend the movable rod of the electric push rod 203, so that the electric push rod 203 drives the primary movable plate 201 to move to a deeper water level through the connecting block 204 connected thereto, thereby moving the sampling bottle 50 to a deeper level for sampling through the movement of the primary movable plate 201; while the primary movable plate 201 is moving, it can drive the secondary telescopic assembly 40 to move downward along the primary movable plate 201 through the transmission assembly 30, and the mutual cooperation between the primary movable plate 201 and the secondary telescopic assembly 40 can further increase the stroke of the device, so that the device can sample at a deeper depth and expand the sampling range of the device; the primary movable plate 201 and the secondary telescopic assembly 40 can limit the sampling bottle 50 underwater to prevent the sampling bottle 50 from moving under the impact of the water flow, thereby improving the stability of the sampling bottle 50, and keeping multiple sampling bottles 50 stably at a fixed water level for sampling during the sampling process, thereby improving the accuracy of stratified sampling of the device and realizing synchronous sampling of water levels at different depths.

[0022] Specific reference Figure 4 , Fig.10 The secondary telescopic component 40 includes: a secondary moving plate 401, which is slidably mounted on one side in front of the primary moving plate 201; a slide rail 402, on which the slide rail 402 is fixedly mounted on one side in front of the primary moving plate 201 close to the electric push rod 203, and both ends of the slide rail 402 are open; a second slider 403, in which a second slider 403 is slidably mounted, and the front of the second slider 403 is fixedly connected to the rear of the secondary moving plate 401; the secondary moving plate 401 moves under the drive of the transmission component 30.

[0023] When the device is taking water samples, while the primary movable plate 201 moves downward, the transmission assembly 30 can drive the secondary movable plate 401 to move, and the secondary movable plate 401 further moves downward and extends along the primary movable plate 201, which can greatly improve the sampling depth of the device. The second slider 403 and the slide rail 402 cooperate with each other to limit the secondary movable plate 401 accordingly, thereby improving the stability of the secondary movable plate 401 during movement.

[0024] Specific reference Figure 5 , Fig. 9 The transmission assembly 30 includes: a rotating shaft 301, the rotating shaft 301 is fixedly installed on the upper and lower parts of the front of the primary movable plate 201, and the two rotating shafts 301 are symmetrically arranged in front of the primary movable plate 201; a synchronous wheel 302, the upper part of the rotating shaft 301 is bearing-mounted with a synchronous wheel 302; a synchronous belt 303, the two synchronous wheels 302 are connected through the synchronous belt 303; a fixed frame 304, a fixed frame 304 is fixedly installed on the side of the front of the base plate 10 close to the primary movable 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; a fixed splint 305, a fixed splint 305 is fixedly installed on the upper part of the other side of the synchronous belt 303, and one side of the fixed splint 305 is fixedly connected to the side opposite to the secondary movable plate 401.

[0025] When the device is in use, when the primary movable plate 201 moves downward, the rotating shaft 301 located in front of the primary movable 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 movable plate 201 moves downward relative to the fixed frame 304. Conversely, the fixed frame 304 drives the left side of the synchronous belt 303 connected thereto upward relative to the primary movable plate 201 to move. At this time, the synchronous belt 303 can be regarded as rotating clockwise, and then the fixed clamping plate 305 installed on the right side of the synchronous belt 303 can drive the secondary movable plate 401 to move downward, thereby extending the secondary movable plate 401. Through this structural design, the stroke of the sampling bottle 50 installed in front of the secondary movable plate 401 can be doubled, thereby realizing the sampling operation of deeper water levels.

[0026] Specific reference Figure 2 , Fig.11 , a plurality of evenly distributed fixed blocks 60 are fixedly installed from top to bottom in front of the secondary moving plate 401, a T-shaped limiting groove 601 with a top surface opening is provided in front of the fixed block 60, and a T-shaped clamping block 602 matching with the T-shaped limiting groove 601 is fixedly installed in the upper part of the rear of the sampling bottle 50, the T-shaped clamping block 602 is vertically inserted into the T-shaped limiting groove 601 and slidably matched therewith, and the T-shaped clamping block 602 is clamped with the corresponding fixed block 60 through the limiting assembly 70. The fixed block 60 arranged in front of the secondary moving plate 401 can facilitate the installation and disassembly of the sampling bottle 50. When in use, the T-shaped clamping block 602 can be inserted from top to bottom into the corresponding T-shaped limiting groove 601 to realize the installation of the sampling bottle 50. The structure is simple and easy to operate. The limiting assembly 70 can prevent the T-shaped clamping block 602 from being separated from the T-shaped limiting groove 601, thereby further improving the stability of the device.

[0027] Specific reference Fig.12The limiting assembly 70 includes: a rectangular frame 701, a card slot 603 is provided on the upper part of the front of the T-shaped limiting slot 601, and a rectangular frame 701 arranged opposite to the card slot 603 is fixedly installed on the top surface of the sampling bottle 50; an insert block 702, an insert block 702 is slidably installed in the rectangular frame 701, and the rear end of the insert block 702 can be inserted into the card slot 603 and engaged with the card slot, and the bottom of the end of the insert block 702 facing the card slot 603 is a wedge-shaped structure, and a rectangular groove is provided on the top surface of the insert block 702 away from the card slot 603, and the rectangular groove is convenient for the user to pass the finger Pull the plug block 702; the limiting rod 704, the limiting holes 703 are respectively opened on both sides of the front of the rectangular frame 701, and the limiting rods 704 are slidably installed in the limiting holes 703; the limiting plates 705, two symmetrically arranged limiting plates 705 are respectively fixedly installed on both sides of the plug block 702, and the two ends of the limiting rod 704 are respectively fixedly connected to the inner sides of the corresponding limiting plates 705; the reset spring 706, the outer side of the limiting rod 704 is sleeved with a reset spring 706, and the reset spring 706 is located between the rectangular frame 701 and the limiting plate 705 at the rear.

[0028] When installing the sampling bottle 50, the T-shaped block 602 is inserted into the corresponding T-shaped limit groove 601 from top to bottom. When the inclined surface at the end of the plug block 702 contacts the top of the T-shaped limit groove 601, the plug block 702 is pushed forward. At this time, the return spring 706 is compressed. When the T-shaped block 602 is fully inserted into the corresponding T-shaped limit groove 601 and the plug block 702 is aligned with the corresponding slot 603, under the action of the elastic force of the return spring 706, the plug block 702 can be pushed backward through the limit plate 705 to be inserted into the slot 603, thereby limiting the sampling bottle 50 and preventing the sampling bottle 50 from loosening under the action of buoyancy after entering the water, thereby improving the reliability of the sampling bottle 50. When the sampling bottle 50 needs to be removed, the user can manually pull the plug block 702 to disengage it from the slot 603, thereby releasing the limit on the sampling bottle 50, facilitating the removal of the sampling bottle 50 and facilitating use.

In the initial state, the first piston 503 is located at the bottom of the sampling bottle 50 and can close the water inlet 504. When the piston rod 502 moves upward, it drives the first piston 503 to move synchronously, and the water inlet 504 is opened. At this time, negative pressure is generated inside the sampling bottle 50 to suck water into the sampling bottle 50.

The delayed start component 80 can realize simultaneous operation of multiple sampling bottles 50, thereby realizing synchronous stratified sampling of different depths of the water source.

[0031] Specific reference Figure 4The delayed start component 80 includes: a strip plate 801, a strip plate 801 is slidably mounted on the side of the front of the secondary movable plate 401 close to the electric push rod 203; an L-shaped connecting plate 802, an L-shaped connecting plate 802 is fixedly mounted on the upper part of the strip plate 801 close to the electric push rod 203; a fixed seat 803, a fixed seat 803 is fixedly mounted on the upper part of one side of the secondary movable plate 401, and the fixed seat 803 is located above the L-shaped connecting plate 802 and arranged opposite to it; a guide rod 804, a guide hole 805 is opened on the top surface of the fixed seat 803, and a guide rod 804 is slidably mounted in the guide hole 805, the lower end of the guide rod 804 is fixedly connected to the top surface of the L-shaped connecting plate 802, and the upper end of the guide rod 804 is fixedly mounted with an anti-slip plate 806 that abuts the top surface of the fixed seat 803, through The anti-slip plate 806 is provided to prevent the guide rod 804 from escaping from the guide hole 805, thereby preventing the guide rod 804 from falling; the spring 807, the outer part of the guide rod 804 is provided with a spring 807, and the spring 807 is located between the L-shaped connecting plate 802 and the fixed seat 803; the stopper 808, the lower part of the primary movable plate 201 close to the electric push rod 203 is fixedly installed with a stopper 808, and the stopper 808 is arranged opposite to the L-shaped connecting plate 802; the L-shaped push rod 809, the upper end of the piston rod 502 is fixedly installed with an L-shaped push rod 809, and the lower end of the L-shaped push rod 809 is fixedly installed with a push plate 810 in an integrated manner; the support plate 811, the side of the strip plate 801 close to the sampling bottle 50 is fixedly installed with a plurality of support plates 811 corresponding to the push plates 810, and the support plates 811 are all located below the corresponding push plates 810.

[0032] In this embodiment, the stopper 808 can be installed on the side of the primary movable plate 201 by bolts, and a first screw hole can be opened on one side of the stopper 808. At the same time, corresponding second screw holes are started at different positions on the side of the primary movable plate 201, so that the user can adjust the position of the stopper 808. The higher the stopper 808 is, the faster the L-shaped connecting plate 802 approaches the stopper 808 when moving, thereby realizing the adjustment of the triggering depth of the delayed start component 80, which is convenient for adjusting different sampling depths.

[0033] When extracting water samples through the sampling bottle 50, the strip plate 801 is installed on the front part of the secondary movable plate 401 through the mutual cooperation of the fixed seat 803, the guide rod 804, and the L-shaped connecting plate 802.
