Description

Technical Field

[0001] This invention relates to the field of water environment monitoring equipment technology, and in particular to a combined water environment monitoring device. Background Technology

[0002] The water environment mainly consists of two parts: surface water environment and groundwater environment. The water environment is one of the basic elements constituting the environment. It is an important place for human society to survive and develop, and it is also the area most seriously affected by human interference and damage. Therefore, in order to further maintain the healthy development of the water environment, it is necessary to conduct regular monitoring of the water environment.

[0003] For example, Chinese utility model patent CN210402654 U discloses a combined portable water environment pollution disaster monitoring device, including a fixed ring, multiple floating support parts detachably connected to the circumference of the fixed ring, a monitoring part for water environment monitoring provided above the fixed ring, and multiple detachable support parts between the monitoring part and the fixed ring; the floating support part includes a first connecting end, a second connecting end, a connecting rod and a float, the first connecting end is fixed to the outer wall of the fixed ring, the second connecting end is fixed to the float, and the two ends of the connecting rod are detachably connected to the first connecting end and the second connecting end; the support part includes a support column, the bottom of the support column is detachably connected to the fixed ring, and the monitoring part is fixed to the support column.

[0004] However, the aforementioned patents cannot perform mobile testing in designated water areas during water environment monitoring, nor can they detect water quality at different depths, resulting in incomplete testing data. This invention addresses these shortcomings by designing a device that can detect water quality at different distances from the shore within a testing environment. Furthermore, this device can sample and test at any depth to determine water quality at different depths. By sampling water at different depths in real time and combining it with the detection mechanism on the base frame, the detection speed is faster, and the detection results are richer and more accurate.

Detailed Implementation

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention. Example

[0033] like Figure 1 As shown, a water environment monitoring combined device includes: an automatic sampling mechanism 1, an automatic detection and drainage mechanism 2, a device movement auxiliary mechanism 3, and a control device; the automatic sampling mechanism 1 is slidably mounted on the device movement auxiliary mechanism 3, and the water sample in the automatic sampling mechanism 1 is detected by the automatic detection and drainage mechanism 2, which is fixedly mounted on the device movement auxiliary mechanism 3; the control device controls the operation of the entire water environment monitoring combined device except for itself.

[0034] Specifically, the device's moving auxiliary mechanism 3 is equipped with a base frame support 301, a base frame 307, a diving rod 309, and a belt 308. The base frame support 301 is fixedly installed on the ground. The base frame 307 is slidably installed on the base frame support 301 and is driven by a motor 316 fixedly installed on the base frame 307. The diving rod 309 is rotatably installed on the base frame 307 and is driven by a hydraulic cylinder 302 rotatably installed on the base frame 307. The belt 308 passes over the driving wheel 311 rotatably installed on the base frame 307, the driven wheel 313 rotatably installed on the diving rod 309, and the belt tensioning mechanism 31 fixedly installed on the base frame 307, and is driven by a motor 315 fixedly installed on the base frame 307. The diving rod 309 has a toothed structure on the side corresponding to the belt 308.

[0035] As a specific implementation method of this embodiment, such as Figure 2-4 As shown in Figure 6, racks are provided on the front and rear sides of the base bracket 301. Two symmetrically mounted brackets 314 are fixedly installed on the base plate 307. A drive shaft 306 is rotatably mounted on the bracket 314 near the bottom. Gears 305 are fixedly mounted on both ends of the drive shaft 306. The two gears 305 mesh with the racks on the front and rear sides of the base bracket 301, respectively. A motor 316 is fixedly mounted on one side of the front bracket 314, and a gear 303 is rotatably mounted on the other side. The gear 303 is connected to the output end of the motor 316 that passes through the bracket 314. A gear 304 is also fixedly mounted on the drive shaft 306, and the gear 304 meshes with the gear 303.

[0036] As a specific implementation method of this embodiment, such as Figure 4 As shown, the base frame 307 has a clearance in the middle for the automatic sampling mechanism 1 to pass through, and a vertical plate corresponding to the belt 308 is provided; a connecting block 317 is rotatably installed at the lower end of the base plate 307 corresponding to the vertical plate on the base plate 307, and a diving rod 309 is fixedly installed at the lower end of the connecting block 317. The diving rod 309 is rotatably connected to the output end of the hydraulic cylinder 302. When the output end of the hydraulic cylinder 302 pushes the diving rod 309 to a vertical state, the upper end of the diving rod 309 corresponds to the lower end of the vertical plate on the base frame 307, which enables the automatic sampling mechanism 1 to slide smoothly.

[0037] A drive shaft 310 is rotatably mounted on the upper end of the fixed frame 314 and is connected to the output end of the motor 315 fixedly mounted on the fixed frame 314. A drive wheel 311 is fixedly mounted on the drive shaft 310.

[0038] After the base frame bracket 301 is fixed, start motor 4 316. The rotation of motor 4 316 will drive the transmission shaft 306 to rotate, thereby moving the base frame 307. It can be moved to a designated position at a distance from the shore according to actual needs. After reaching the designated position, start hydraulic cylinder 302 to push the diving rod 309 to a vertical position. Then start motor 315. Motor 315 will drive the transmission shaft 2 310 to rotate, thereby driving belt 308 to rotate.

[0039] Specifically, the belt tensioning mechanism 31 is provided with a limit rod 3104; the limit rod 3104 has sliders 3103 fixedly installed symmetrically at both ends, and a driven wheel 3102 rotatably installed in the middle; the two sliders 3103 are slidably installed on the base frame 307, and are elastically connected to the base frame 307 by a compression spring 3101; the belt 308 passes over the driving wheel 311, the driven wheel 313 and the driven wheel 3102 respectively, and is driven by the motor 315.

[0040] As a specific implementation method of this embodiment, such as Figure 5 As shown, the base frame 307 has two sliding holes at its front end, and two sliders 3103 are respectively slidably installed on the two sliding holes on the base frame 307; the belt 308 is kept taut by the elastic force of the compression spring 3101.

[0041] Specifically, the automatic sampling mechanism 1 is equipped with a sampling box 103, a lever 101, a sliding rod 105, a partition 106, and a backstop mechanism 11. The sampling box 103 is slidably mounted on the base frame 307 and the diving rod 309, and is fixedly mounted on the belt 308. The front end of the lever 101 engages with the toothed structure on the diving rod 309. The lever 101 rotates and is slidably mounted on the sampling box 103, and the rotation of the lever 101 is limited by a protrusion on the sampling box 103. The sliding rod 105 is slidably mounted on the lever 101, and one end of the sliding rod is slidably mounted on the lever 101. The compression spring 104 is elastically connected to the lever 101, and the other end abuts against one end of the sampling box 103 and slides and rotates along one end of the sampling box 103; the partition 106 is simultaneously slidably installed on the other end of the sampling box 103 and the lever 101, and is located on the side away from the diving rod 309; the partition 106 has an opening; the sampling box 103 has openings on the left and right sides and the bottom plate, and water inlets are opened corresponding to the openings on the partition 106; the anti-reverse mechanism 11 is fixedly installed on the sampling box 103 and corresponds to the openings on the sampling box 103.

[0042] As a specific implementation method of this embodiment, such as Figure 7 and 15As shown, the sampling box 103 is fixedly mounted on the belt 308. The lever 101 has a sliding hole on its head. A limiting post 102 is fixedly mounted on the sampling box 103. The limiting post 102 limits the lever 101, allowing it to slide and rotate on one side of the sampling box 103. The protrusion on the sampling box 103 is intermittently connected to the lever 101, which limits the maximum rotation angle of the lever 101. The partition 106 is slidably mounted on the sampling box 103, and a push rod 107 is fixedly mounted on it. The two ends of the push rod 107 are slidably mounted on the rear end of the lever 103. The distance from the limiting post 102 to the end face of the sampling box 103 corresponding to the partition 106 is constant. The lever 101 is long enough to allow the push rod 107 to slide continuously on the lever 101.

[0043] When in use, this device can sample at different depths to obtain more comprehensive data. Specifically, during sampling, belt 308 rotates under the drive of motor 315, causing sampling box 103 to slide downwards along the upright plate on base frame 307 and diving rod 309. During the sliding process, the tip of lever 101 engages with the toothed structure on diving rod 309, with the tip facing upwards. After sliding to the designated position, belt 308 rotates in the opposite direction a short distance under the drive of motor 315, causing sampling box 103 to move upwards a short distance, so that the tip of lever 101 engages with the toothed structure on diving rod. This causes lever 101 to rotate until it is exactly horizontal, at which point belt 308 stops, and lever 101 rotates, causing partition 106 to slide upwards. The opening on partition 106 coincides with the water inlet on sampling box 103, allowing water at this depth to enter sampling box 103. When the water is full, the belt 308 rotates upward, thereby moving the sampling box 103 upward. At this time, the lever 101 continues to rotate, causing the partition 106 to slide upward again, so that the partition 106 blocks the water inlet of the sampling box 103 again, thereby sealing the sampling box 103 and ensuring that the water sample is taken at this depth. As the lever 101 continues to rotate from the middle position, the sliding rod 105 extends under the action of the compression spring 104 and abuts against one end of the sampling box 103. Through the cooperation of the sliding rod 105 and the compression spring 104, the lever 101 is always in contact with the toothed structure of the diving rod. The lever 101 is inclined at the tooth angle to these toothed structures, and can slide smoothly on the teeth until the sampling box 103 is brought out to the designated position. At this time, under the action of the compression spring 104, the rod head of the lever 101 will always be in the facing state, and the water sample is preserved inside the sampling box 103.

[0044] Specifically, the check valve mechanism 11 is provided with a valve bracket 1101, a side plate check valve 1103, a second limiting post 1104, and a bottom plate check valve 1106. The valve bracket 1101 is fixedly installed on the sampling box 103 corresponding to the two openings on the left and right sides of the sampling box 103. The two side plate check valves 1103 are slidably installed on the valve bracket 1101, and the two side plate check valves 1103 are elastically connected by a compression spring 1102 provided on the valve bracket 1101. The second limiting post 1104 is fixedly installed on the sampling box 103 corresponding to the opening on the bottom plate of the sampling box 103. The bottom plate check valve 1106 is slidably installed on the second limiting post 1104, and is elastically connected to the second limiting post 1104 by a compression spring 1105 provided on the second limiting post 1104.

[0045] As a specific implementation method of this embodiment, such as Figure 8 As shown, there are two valve supports 1101, one above the other, which are fixed inside the sampling box 103. The side plate check valve 1103 is pressed tightly against the sampling box 103 by the action of the compression spring 1102. There are three limit posts 1104, which are fixedly installed at the bottom of the sampling box 103. The bottom plate check valve 1106 is pressed tightly against the bottom of the sampling box 103 by the action of the compression spring 1105. The check mechanism 11 prevents the water sample in the sampling box 103 from flowing out of the opening provided on the sampling box 103 without the action of external force.

[0046] Specifically, the automatic detection and drainage mechanism 2 is equipped with a sample storage box 202 and an automatic drainage mechanism 21; the two sample storage boxes 202 are slidably mounted on the base frame 307 corresponding to the openings on the left and right sides of the sampling box 103, and are driven by a motor 203 fixedly mounted on the base frame 307; water quality detector A201 and water quality detector B204 are fixedly mounted on the two sample storage boxes 202 respectively; the sample storage boxes 202 discharge the water sample inside through the automatic drainage mechanism 21.

[0047] As a specific implementation method of this embodiment, such as Figure 9-10 As shown in Figure 12, each of the two sample storage boxes 202 has a rack frame 205 fixedly installed at one end, and a rack is provided on the other end of each rack frame 205; the second motor 203 is located in the middle of the two rack frames 205; the output end of the second motor 203 is fixedly connected to a gear a (not shown in the figure), and the gear a meshes with the racks on the two rack frames 205.

[0048] When the sampling box 103 brings the water sample to the designated location, it is tested. The rack and pinion frame 205 on the top of the storage box 202 slides towards each other under the drive of the motor 203, so that the two storage boxes 202 slide towards the sampling box 103 until the storage box 202 hits the opening on the side of the sampling box 103 and opens the side plate check valve 1103, so that the water sample in the sampling box 103 flows into the storage box 202. Water quality detectors A201 and B204, which measure different data, are respectively installed on the sides of the two storage boxes 202, so as to perform real-time detection of the water sample and obtain specific data.

[0049] Specifically, the automatic drainage mechanism 21 is equipped with a baffle 2101, a lever mounting bracket 2104, a bidirectional lead screw 2105, an inclined slider 2107, and an arc-shaped rack 2109; baffles 2101 are rotatably mounted on the bottom of each of the two sample storage boxes 202, and the two baffles 2101 are respectively connected to the spring pieces 2102 fixedly mounted on the two sample storage boxes 202; the lever mounting bracket 2104 is fixedly mounted on the base frame 307, and two levers 2103 are rotatably mounted on it; the bidirectional lead screw 2105 rotates... The device is mounted on the base frame 307 and driven by a motor 2110 fixedly mounted on the base frame 307; two inclined sliders 2107 are slidably mounted on a two-way lead screw 2105; two levers 2103 are respectively engaged at one end with the inclined sliders 2107 and at the other end with the baffle 2101; an arc-shaped rack 2109 is slidably mounted on the base frame 307 and intermittently engages with the bottom plate check valve 1106; the arc-shaped rack 2109 meshes with a gear 2108 fixedly mounted on the two-way lead screw 2105.

[0050] As a specific implementation method of this embodiment, such as Figure 13 As shown, the spring 2102 is located at the bottom of one end of the baffle 2101, so that the other end of the baffle 2101 is in close contact with the bottom of the sample storage box 202. At this time, the water sample cannot flow out from the bottom of the sample storage box 202.

[0051] As a specific implementation method of this embodiment, such as Figure 9-12As shown, the base frame 307 is equipped with a bracket for mounting a bidirectional lead screw 2105, a sliding beam 2106, and a motor 2110. The bidirectional lead screw 2105 is rotatably mounted on the bracket on the base frame 307, and sliding beams 2106 are symmetrically fixedly mounted on both sides of the bidirectional lead screw 2105. One end of the bidirectional lead screw 2105 is fixedly connected to a gear 2112. The motor 2110 is fixedly mounted on the bracket on the base frame 307, and its output end is fixedly connected to a gear 2111. It meshes with gear 3 2112; the inclined plane slider 2107 is slidably mounted on the double-acting screw 2105 and the sliding beam 2106. With the support of the sliding beam 2106, the inclined plane slider 2107 can slide more smoothly; the end of the lever 2103 away from the baffle 2101 is provided with a counterweight (not shown in the figure), which can make the other end of the lever 103 separate from the baffle 2101 without the action of external force; the gear 2108 is located at the center of the double-acting screw 2105.

[0052] After the test is completed, the water in the sampling box 103 and the storage box 202 needs to be drained. Specifically, the bidirectional lead screw 2105 rotates under the drive of the motor 2110, which in turn drives the gear 2108 in the middle to rotate. The gear 2108 drives the arc rack 2109 to rotate. At the same time, the bidirectional lead screw 2109 drives the two inclined sliders 2107 to move to both sides. When the arc rack 2109 rotates to open the bottom plate check valve 1106, the synchronously moving inclined sliders 2107 also lift one end of the lever 2103. The other end of the lever 2103 just presses down the baffle 2101, so that the water in the sampling box 103 flows out from the bottom and the water in the storage box 202 flows out from the bottom openings at both ends, thus draining the water sample. Then the motor 2110 reverses and resets the automatic drainage mechanism 21.

[0053] After the inspection is completed, the hydraulic cylinder 302 is activated to retract the telescopic rod, which in turn drives the submersible rod 309 to rotate, bringing the submersible rod 309 to a horizontal position. When the submersible rod 309 rotates, the belt 308 has an adaptive function. Then, the motor 316 is activated to bring the base frame 307 back to the shore. This facilitates the maintenance of the equipment, reduces the time it spends in contact with water, and increases the service life of the equipment.

[0054] As a specific implementation of this embodiment, the control device controls the operation of the entire water environment monitoring assembly except for itself.

[0055] Working principle:

[0056] First, start motor 316 to move base frame 307 to the designated position, then start hydraulic cylinder 302 to push submersible rod 309 to the vertical position;

[0057] The second step is to start motor 315, move the automatic sampling mechanism 1 to the designated depth for sampling, and then bring the water sample back to the designated location.

[0058] The third step is to start motor 203 and test the water sample;

[0059] Fourth step: After the test is completed, start motor 2110 to drain the water sample, and then the automatic drainage mechanism 21 will reset.

[0060] Fifth, the hydraulic cylinder 302 retracts, bringing the diving rod 309 into a horizontal retracted state. Then, the motor 316 is started to bring the base frame 307 back to the shore.

[0061] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
