Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and more specifically, to a sampling device for water body inspection. Background Technology

[0002] Water quality testing, as a part of environmental monitoring, usually involves sampling equipment to sample deeper water to facilitate testing at different water levels and improve the accuracy of water quality testing.

[0003] Publication number CN219161711U discloses a water filtration and sampling device. The technical solution includes a box, with several water storage tanks evenly distributed inside the box. A water inlet pipe is provided on the upper side of the box. A water pumping component is provided between the water inlet pipe and the several water storage tanks. A filter component is provided in the water inlet pipe. The box has several drain holes that correspond one-to-one with the several water storage tanks. A drain head is threadedly connected to each of the drain holes. The filter component includes a threaded mounting seat, a filter element mounting shell, a water pumping pipe, and a filter element. The water inlet pipe has a through hole.

[0004] When sampling deep water, the above-mentioned technical solution can filter out sand and other impurities inside the water body through the setting of the filter core, so that the sampled water body is free of sand and other impurities, thereby improving the water quality, making it convenient for testing personnel to use the water body, and improving testing efficiency.

[0005] However, the above-mentioned technical solution involves storing water in a water tank when the water is collected into the sampling device. When staff need to test the water, they need to use multiple test tubes to remove the water from the water tank, which is time-consuming and labor-intensive, affecting the testing efficiency.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a sampling device for water body inspection, which solves the problem that when staff need to test water, they need to use multiple test tubes to take water out of the storage tank, which is time-consuming, labor-intensive, and affects the testing efficiency.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sampling device for water body inspection, comprising a device body and a plurality of test tubes, wherein the device body is provided with a plurality of placement slots for placing test tubes, a rotating block is rotatably connected in the placement slots, a cork is provided at the opening of the test tube, the cork and the rotating block are detachably connected, and the device body is provided with a driving component for driving the rotating block to rotate and a conveying component for conveying water into the test tube.

[0009] By employing the aforementioned technical solution, when sampling water, the opening of the test tube is connected to a cork. A drive assembly then rotates a rotating block. When the rotating block tilts upwards, it stops rotating. The cork and rotating block are then reassembled. The drive assembly then returns the rotating block to its original position, moving the test tube into the placement slot. Finally, a conveying assembly delivers water into the test tube, thus achieving water sampling. The conveying assembly, rotating block, and cork allow for direct delivery of sampled water into the test tube, eliminating the need for secondary sampling and reducing operational steps, thereby improving testing efficiency.

[0010] The present invention is further configured such that: the driving component includes a knob rotatably connected to the side wall of the device body; a connecting rod is fixedly connected between the rotating blocks; the connecting rod is rotatably connected to the device body; one of the connecting rods passes through the device body and is fixedly connected to the knob; and the knob and the device body are connected by a snap-fit ​​device to self-lock the knob.

[0011] By sampling the above technical solution, when the rotating block is driven to rotate, the knob is turned, which drives the connecting rod to rotate. The connecting rod then drives several rotating blocks to rotate, thereby achieving the effect of driving the rotating block to rotate. At the same time, the locking mechanism can self-lock the knob, making it easy to control the orientation of the rotating block.

[0012] The present invention is further configured such that: the snap-fit ​​component includes several grooves formed on the side wall of the device body, the grooves are arranged in a ring array along the knob, a ball is slidably connected in the groove, the ball and the groove are connected by a spring, and the knob is provided with a slot for snapping the ball.

[0013] By sampling the above technical solution, when the knob is rotated, the knob causes the locking block and the ball to separate from each other, and the ball enters the groove. At this time, the spring is deformed and compressed, and then continues to drive the knob to rotate, so that the other locking groove and the ball are aligned. At this time, the spring loses its restriction and deforms back to its original position, and drives the ball to lock with the locking groove. At this time, the knob is restricted and cannot rotate, thereby achieving the effect of driving the knob to self-lock.

[0014] The present invention is further configured such that: the conveying assembly includes a gear pump and a water delivery hose; a cavity for installing the gear pump is provided inside the device body; the water delivery hose is fixedly connected to the output end of the gear pump; the water delivery hose passes through the device body and the rotating block and is fixedly connected to the device body and the rotating block; an inlet for inserting the water delivery hose is provided on the cork; a plurality of thin films are fixedly connected to the inlet; when the thin films are in their natural state, one side wall of the thin films is in contact with each other; an inlet pipe is detachably connected to the input end of the gear pump; and an exhaust device is provided on the device body for discharging the cavity inside the test tube outward.

[0015] By employing the above-described sampling technique, when water is delivered to the test tube, the water delivery hose is inserted into the inlet, causing the membrane to deform. The inlet pipe is then placed in the water, and the gear pump is activated. This pump expels air from the water delivery hose and inlet pipe into the test tube, while simultaneously venting air from the test tube. The loss of air in the delivery pipe draws water into it, which is then pumped into the test tube by the gear pump. This process of delivering water to the test tube achieves the desired water delivery. When removing the test tube, simply pull the delivery pipe out of the cork. The membrane then deforms and returns to its original shape, causing one side wall of the membrane to adhere to the other side. The water inside the test tube, affected by the membrane, cannot flow out through the inlet, thus achieving the effect of water sampling.

[0016] The present invention is further configured such that: the exhaust component includes an exhaust hose and a vent valve, the vent valve is fixedly connected to the equipment body, the exhaust hose is fixedly connected to the input end of the vent valve, the exhaust hose passes through the equipment body and the rotating block and is fixedly connected to the equipment body and the rotating block, the cork has an exhaust port for inserting the exhaust hose, and a plurality of thin films are fixedly connected to the exhaust port. When the thin films are in their natural state, the sidewalls of the thin films are in contact with each other.

[0017] By sampling the above technical solution, when the air in the test tube is discharged outward, the exhaust hose is inserted into the air outlet, causing the membrane to deform. Then, the vent valve is activated, and the vent hose connects the vent valve and the test tube. The vent valve allows the air in the test tube to be discharged outward, thus achieving the effect of discharging the air in the test tube.

[0018] The present invention is further configured such that: a connecting pipe is fixedly connected to the input end of the gear pump, the connecting pipe passes through the equipment body to the outside and is fixedly connected to the equipment body, an installation ring is fixedly connected to one end of the connecting pipe located on the outside, and a nut is fixedly connected to one end of the water inlet pipe, and the nut is threadedly connected to the outer wall of the installation ring.

[0019] By sampling the above technical solutions, it is easy to install and disassemble the water inlet pipe and the input end of the gear pump, which facilitates operation by staff.

[0020] The present invention is further configured such that: a power source is fixedly connected inside the cavity, the gear pump and the vent valve are both electrically connected to the power source, and a switch is provided on the device body, the switch being electrically connected to the power source.

[0021] By using the above-mentioned technical solutions, the sampling equipment can be made to operate without distance limitations, thus improving its practicality.

[0022] In summary, this utility model has the following beneficial effects: When sampling water, the rotating block is driven by the driving component to rotate, and the test tube is put into the placement groove. Then, the water is transported into the test tube by the conveying component, thereby achieving the effect of water sampling. By setting up the conveying component, the rotating block and the cork, the sampled water can be directly transported into the test tube, eliminating the need for staff to use test tubes to perform secondary sampling of water, reducing the number of operation steps for staff and improving the detection efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] A water sampling device for water body inspection, such as Figures 1-6 As shown, the device includes a main body 1 and several test tubes 2. The main body 1 has several placement slots 3 for placing the test tubes 2. A rotating block 4 is rotatably connected within each placement slot 3. A cork stopper 5 is provided at the opening of each test tube 2. The cork stopper 5 and the rotating block 4 are detachably connected. The main body 1 has a drive assembly for driving the rotating block 4 to rotate and a delivery assembly for delivering water into the test tubes 2. When sampling water, the opening of the test tube 2 is connected to the cork stopper 5, and then the drive assembly drives the rotating block 4 to rotate. When block 4 tilts upward, it drives the rotating block 4 to stop rotating. Then, the cork stopper 5 and the rotating block 4 are installed together. Then, the rotating block 4 is driven back to its original position by the driving component, and the test tube 2 is driven into the placement groove 3. Finally, the water is transported into the test tube 2 by the conveying component, thereby achieving the effect of water sampling. Through the setting of the conveying component, the rotating block 4 and the cork stopper 5, the sampled water can be directly transported into the test tube 2, eliminating the need for the staff to use the test tube 2 to perform a second sampling of the water, reducing the number of steps for the staff and improving the detection efficiency.

[0034] like Figures 1-3As shown, the drive assembly includes a knob 6 rotatably connected to the side wall of the device body 1, a connecting rod 7 fixedly connected between the rotating blocks 4, the connecting rod 7 and the device body 1 being rotatably connected, wherein one connecting rod 7 passes through the device body 1 and is fixedly connected to the knob 6, the knob 6 and the device body 1 are connected by a snap-fit ​​device to self-lock the knob 6, the snap-fit ​​device includes several grooves 8 formed on the side wall of the device body 1, the grooves 8 are arranged in a ring along the knob 6, a ball 9 is slidably connected in the groove 8, the ball 9 and the groove 8 are connected by a spring 10, and the knob 6 is provided with a slot 11 for the ball 9 to snap into.

[0035] When the rotating block 4 is driven to rotate, the knob 6 is turned, which drives the connecting rod 7 to rotate. The connecting rod 7 drives several rotating blocks 4 to rotate, thus achieving the effect of driving the rotating block 4 to rotate. At the same time, as the knob 6 rotates, the knob 6 drives the locking block and the ball 9 to separate from each other, and the ball 9 enters the groove 8. At this time, the spring 10 is deformed and compressed. Then, the knob 6 is driven to rotate, so that the other locking groove 11 corresponds to the position of the ball 9. At this time, the spring 10 loses its restriction and deforms and returns to its original shape, and drives the ball 9 to lock with the locking groove 11. At this time, the knob 6 is restricted and cannot rotate, thus achieving the effect of driving the knob 6 to self-lock.

[0036] like Figures 4-6 As shown, the conveying assembly includes a gear pump 12 and a water delivery hose 13. A cavity for installing the gear pump 12 is provided inside the equipment body 1. The water delivery hose 13 is fixedly connected to the output end of the gear pump 12. The water delivery hose 13 passes through the equipment body 1 and the rotating block 4 and is fixedly connected to both. An inlet 14 for inserting the water delivery hose 13 is provided on the cork plug 5. Several membranes 15 are fixedly connected to the inlet 14. When the membranes 15 are in their natural state, their sidewalls are in contact with each other. A water inlet pipe 1 is detachably connected to the input end of the gear pump 12. 6. The device body 1 is provided with an exhaust device for discharging the cavity inside the test tube 2 outward. The exhaust device includes an exhaust hose 17 and a vent valve 18. The vent valve 18 is fixedly connected to the device body 1. The exhaust hose 17 is fixedly connected to the input end of the vent valve 18. The exhaust hose 17 passes through the device body 1 and the rotating block 4 and is fixedly connected to the device body 1 and the rotating block 4. The cork stopper 5 has an exhaust port 19 for the exhaust hose 17 to be inserted. Several thin films 20 are fixedly connected to the exhaust port 19. When the thin films 20 are in their natural state, the side walls of the thin films 20 are in contact with each other.

[0037] When water is delivered to test tube 2, the water delivery hose 13 and the vent hose 17 are inserted into the inlet 14 and vent 19 respectively, causing the membrane 15 and membrane 20 to deform. Then, the inlet pipe 16 is placed in the water, and the gear pump 12 is started to drive the gear pump 12 to expel the air in the water delivery hose 13 and the inlet pipe 16 into test tube 2. At the same time, the air release valve 18 vents the air out of test tube 2. At this time, the water delivery pipe will be sucked into the water delivery pipe due to the loss of air, and the water will be delivered into the water delivery pipe by the gear pump 12. The water is delivered into test tube 2 through the water delivery pipe, thus achieving the effect of delivering water into test tube 2. When test tube 2 is removed, the water delivery pipe is simply pulled out from the cork 5. At this time, membrane 15 deforms and recovers, causing the side walls of membrane 15 to stick together. The water in test tube 2 is unable to flow out through the inlet 14 due to the influence of membrane 15, thus achieving the effect of water sampling.

[0038] like Figure 4 As shown, the input end of the gear pump 12 is fixedly connected to a connecting pipe 21. The connecting pipe 21 passes through the equipment body 1 to the outside and is fixedly connected to the equipment body 1. The end of the connecting pipe 21 located on the outside is fixedly connected to an installation ring 22. One end of the water inlet pipe 16 is fixedly connected to a nut 23. The nut 23 and the outer wall of the installation ring 22 are threaded together, which facilitates the installation and disassembly of the water inlet pipe 16 and the input end of the gear pump 12, making it convenient for operators to operate.

[0039] like Figure 2 As shown, a power supply 24 is fixedly connected inside the cavity. The gear pump 12 and the vent valve 18 are both electrically connected to the power supply 24. A switch 25 is provided on the device body 1, and the switch 25 is electrically connected to the power supply 24. This allows the sampling device to be used without distance limitations during sampling, improving the practicality of the sampling device.

[0040] The working principle of this utility model is as follows: When sampling water, the opening of test tube 2 is connected to cork 5. Then, knob 6 is turned, which drives connecting rod 7 to rotate. Connecting rod 7 drives several rotating blocks 4 to rotate. Then, water delivery hose 13 and exhaust hose 17 are inserted into water inlet 14 and exhaust outlet 19 respectively, causing membrane 15 and membrane 20 to deform. Then, rotating blocks 4 are driven back to their original positions, and test tube 2 is driven into placement tank 3. Then, water inlet pipe 16 is placed into water, and then gear pump 12 is started, driving gear pump 12... The air in the water delivery hose 13 and the water inlet pipe 16 is expelled into the test tube 2. At the same time, the air release valve 18 expels the air out of the test tube 2. At this time, the water delivery hose, having lost air, will draw water into the water delivery hose and be transported into the water delivery hose by the gear pump 12. The water is then transported into the test tube 2 through the water delivery hose, thereby achieving the effect of water sampling. With the setting of the delivery component, the rotating block 4, and the cork 5, the sampled water can be directly delivered into the test tube 2, eliminating the need for staff to perform a second sampling of the water using the test tube 2, reducing the number of steps for staff and improving the testing efficiency.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
