Description

Technical Field

[0001] The invention relates to the technical field of sampling devices, in particular to a water source sampling device for environmental engineering. Background Art

[0002] With the development of society, industrial technology is constantly improving, but industrial pollution also comes with it. The environment in which humans live is also deteriorating. Environmental problems cannot be ignored. Water is the source of human life. The problem of water pollution is particularly serious. Therefore, we urgently need a device to detect the quality of water.

[0003] The prior art generally adopts a water source sampling device with a storage function for environmental engineering detection, such as the one disclosed in Patent No. CN109596394B, which includes a horizontal top support plate, an intermediate support plate, a tightening rod, a sliding frame and a T-shaped positioning rod; a hanger is welded and suspended at the bottom of the head end position of the support mounting plate, the end of the hanger is sleeved with a circular top support plate, and the bottom support of the circular top support plate is supported and suspended with a cover plate; the sliding support rod is supported and welded at the top end of the cover plate, and its middle section extends upward and penetrates through the outer eaves position welded to the circular top support plate, and its head end continues to support upward and penetrate through the support mounting plate; the top end of the sliding support rod is welded with a connecting plate, and this top connecting plate is placed on the top end surface of the support mounting plate, and the sliding support rod is located between the circular top support plate and the cover plate. A connecting plate is also welded on the rod section. The rotating positioning rod of the present invention can be rotatably matched with the two long grooves for easy removal and placement of the filter cover.

[0004] The water sampling method of the above scheme and most of the schemes in the prior art is as follows: water is sampled by the cooperation of a boom and a sampling cup, but this water sampling method is not suitable for sampling water in larger lakes, oceans, etc., so a floating water sampling device is usually used. For example, Patent No. CN107843456A discloses a floating water source sampling device for environmental testing, which includes a protective cover, a support frame, and a water storage tank. A fixing buckle is fixed to the outer side of the protective cover, and a floating disc is connected to the lower side of the protective cover, and a turbine is fixed to the lower side of the floating disc. An electric telescopic rod is provided on the lower side of the floating disc, and a water intake pipe is installed on the outer side of the electric telescopic rod. The upper end of the support frame is connected to the floating disc, and a signal receiver and a single-chip microcomputer are installed on the upper side of the floating disc. A fixing ring is connected between the electric telescopic rod and the water intake pipe. This floating water source sampling device for environmental testing is equipped with a turbine, which facilitates sampling at different locations in the water area, reducing the limitations of the sampling device. It is also equipped with an electric telescopic rod of different lengths, which can sample at different depths underwater, thereby improving the accuracy of water quality testing and facilitating the rapid sampling work.

[0005] However, the above-mentioned water sampling devices need to be driven by limited energy such as electricity, and do not make good use of natural wind power for sampling, so they are in urgent need of change. Summary of the Invention

[0006] The purpose of the present invention is to solve the above problems and to propose a water source sampling device for environmental engineering.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A water source sampling device for environmental engineering, comprising a hull and a support plate arranged thereon, wherein a rod body is vertically slidably connected to the support plate, and a camera is arranged on the top of the rod body;

[0009] The bottom end of the rod body is fixedly connected to a connecting block, the connecting block shaft is connected to a driving gear, and the support plate is provided with a driven liquid-absorbing member used in conjunction with the driving gear at positions on both sides of the driving gear. When the driving gear slides to a certain side, it engages with the driven liquid-absorbing member on that side and transmits the power;

[0010] The bottom end of the hull is provided with a liquid suction microhole and a liquid outlet pipe for sucking liquid.

[0011] Optionally, the driven liquid-absorbing member includes a driven gear, a rotating disk, an elastic locking member, a first connecting rod, a second connecting rod and a flexible plate;

[0012] The driven gear shaft is connected to the support plate, the turntable is welded to the driven gear, the turntable is fixedly connected to the first connecting rod, the first connecting rod is connected to the second connecting rod shaft, and the second connecting rod is connected to the flexible plate shaft;

[0013] The side of the flexible plate is fixed to the hull, and the flexible plate is in contact with the hull when not under tension;

[0014] The elastic locking member is arranged on the rotating disk, and is used to lock the driven gear after rotation.

[0015] Optionally, the elastic locking member is composed of a spindle, a telescopic rod, a spring and a pin;

[0016] The spindle is fixed to the support plate, the driven gear is rotatably connected to the spindle through a bearing, a receiving groove is provided on the turntable, the telescopic rod is arranged in the receiving groove, the spring is sleeved on the telescopic rod, the telescopic rod is fixed to the ball, and a slot for use with the ball is provided on the spindle.

[0017] Optionally, a side of the pin close to the slot adopts an arc-shaped structure, and the slot adopts an arc-shaped structure.

[0018] Optionally, the bottom end of the connecting block is provided with an elastic reset member for resetting the rod body after movement.

[0019] Optionally, the elastic return member is composed of an extension block, a stop block and a return spring;

[0020] The extension block is fixed to the connection block. There are two stoppers, which are symmetrically arranged on the partition. A return spring is welded on the inner side of the partition. The return spring is fixed to the extension block.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The present invention is driven by external wind power and does not require consumption of limited energy such as electricity. The present invention provides a rod body, a driving gear and a driven liquid-absorbing member. When the rod body swings under the action of wind power, it drives the connecting block and the driving gear to slide and rotate until the sliding engages with the driven gear on one side, thereby realizing the separation movement of the flexible plate in the driven liquid-absorbing member and the hull, thereby achieving water intake through the negative pressure between the two. Similarly, when the wind disappears, the rod body and the driving gear are reset, while the driven gear remains fixed under the action of the elastic locking member.

[0023] The present invention provides a sliding groove so that the rod body can drive the driving gear to slide. When the rod body is displaced, the driving gear and the driven gear can be meshed after sliding, and the driven liquid suction piece can be triggered to suck liquid under the action of wind force. The driving gear can also be meshed with only one driven gear at a time, thereby avoiding the false triggering of the driven liquid suction piece on the other side. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-5 A water source sampling device for environmental engineering includes a hull 9 and a support plate 8 arranged thereon, and a rod body 1 is vertically slidably connected to the support plate 8. The support plate 8 should have a horizontal slide groove for the horizontal sliding of the rod body 1. The slide groove is designed to allow the driving gear 5 and the driven gear 61 to engage after sliding when the rod body 1 is displaced, and it can also allow the driving gear 5 to only engage with a certain driven gear 61 at the same time to avoid driving the driven gear 61 on the other side to rotate in the opposite direction.

[0032] A camera 2 is provided at the top of the rod body 1 , and a power supply and a wireless signal transceiver should also be provided on the rod body 1 so that the images captured by the camera 2 can be transmitted.

[0033] The bottom end of the rod body 1 is fixedly connected to a connecting block 3, and the connecting block 3 is axially connected to a driving gear 5. A driven liquid-absorbing part 6 for use with the driving gear 5 is provided on both sides of the supporting plate 8. When the driving gear 5 slides to one side, it engages with the driven liquid-absorbing part 6 on that side and transmits the power.

[0034] The bottom end of the hull 9 is provided with a liquid suction micropore 10 and a liquid outlet pipe 11 for liquid suction. The liquid outlet pipe 11 is used for discharging liquid. A valve should be provided on the liquid outlet pipe 11, and the valve is in a closed state under normal circumstances. When water needs to be discharged, the valve is opened and the water is collected through a container.

[0035] The driven liquid-absorbing member 6 includes a driven gear 61, a rotating disk 62, an elastic locking member 63, a first connecting rod 64, a second connecting rod 65 and a flexible plate 66, as shown in detail below:

[0036] It is worth mentioning that, in this embodiment, the shapes of the flexible plate 66 and the inner wall of the hull 9 are as follows: Figure 1As shown, when it is deformed, a space can be "vacated" between the hull 9 to easily accommodate liquid. The inner wall of the hull 9 can also be made into a shape similar to a tilted piston cylinder, and the flexible plate 66 can be a piston, so that the piston movement of the flexible plate 66 can also be used to suck liquid into the hull 9.

[0037] The driven gear 61 is axially connected to the support plate 8 , the turntable 62 is welded to the driven gear 61 , the turntable 62 is fixedly connected to the first connecting rod 64 , the first connecting rod 64 is axially connected to the second connecting rod 65 , and the second connecting rod 65 is axially connected to the flexible plate 66 .

[0038] The driven gear 61 can drive the turntable 62 to rotate synchronously, and then drive the first connecting rod 64 to flip, and finally pull the second connecting rod 65 to move.

[0039] The side of the flexible plate 66 is fixed to the hull 9, and the flexible plate 66 is attached to the hull 9 when not under tension. Figure 1 As shown, when they are attached to each other, there is no gap between them, thereby preventing liquid from entering. Similarly, when the flexible plate 66 is separated from the hull 9, negative pressure appears between them, thereby allowing liquid to be absorbed.

[0040] The elastic locking member 63 is provided on the rotating disk 62 and is used to lock the driven gear 61 after rotation. The elastic locking member 63 is composed of a spindle 631, a telescopic rod 634, a spring 635 and a pin 636, as shown in the following figure:

[0041] The spindle 631 is fixed to the support plate 8, and the driven gear 61 is rotatably connected to the spindle 631 through a bearing. A receiving groove 633 is provided on the turntable 62, and the telescopic rod 634 is arranged in the receiving groove 633. The spring 635 is sleeved on the telescopic rod 634, and the telescopic rod 634 is fixed to the pin 636. A card slot 632 is provided on the spindle 631 for use with the pin 636.

[0042] The function of the elastic locking member 63 is that when the driven gear 61 drives the turntable 62 to rotate synchronously, the turntable 62 can be locked and fixed by cooperating with the elastic locking member 63 every time it moves to a certain angle (that is, the gap opened between the flexible plate 66 and the hull 9), thereby preventing the turntable 62 from resetting after rotation and causing the flexible plate 66 to push the liquid out again.

[0043] In the elastic locking member 63, the pin 636 has an arc-shaped structure on the side close to the slot 632, and the slot 632 has an arc-shaped structure. This structure can prevent the two from getting stuck, while allowing for easy sliding in and out for fixation.

[0044] In this embodiment, the bottom end of the connecting block 3 is provided with an elastic reset member 4 for resetting the rod body 1 after movement. The elastic reset member 4 is composed of an extension block 41, a stop block 42 and a reset spring 43, as follows:

[0045] The extension block 41 is fixed to the connection block 3 , there are two stop blocks 42 and they are symmetrically arranged on the partition 7 , and a return spring 43 is welded on the inner side of the partition 7 , and the return spring 43 is fixed to the extension block 41 .

[0046] Reference Figure 2 The function of the elastic return member 4 is to make the stopper 42 in the middle position under the elastic force of the return springs 43 on both sides. Since the stopper 42 is fixed to the connecting block 3, and the connecting block 3 is fixedly connected to the rod body 1, the rod body 1, the connecting block 3 and the driving gear 5 are finally in a vertical state without being affected by external wind force. The setting of the spring 43 also provides an initial load to prevent the rod body 1 from shaking at will, and it can only swing under the action of wind force.

[0047] When the rod body 1 swings under the action of wind, it drives the connecting block 3 and the driving gear 5 to slide and rotate until they slide and engage with the driven gear 61 on one side. Then the rod body 1 continues to rotate, and the driving gear 5 drives the driven gear 61 to continue to rotate. The driven gear 61 drives the turntable 62 to rotate, and the turntable 62 drives the first connecting rod 64 to rotate. The first connecting rod 64 drives the second connecting rod 65 to pull the flexible plate 66 to move, thereby finally realizing the separation movement of the flexible plate 66 and the hull 9, thereby achieving water intake through the negative pressure between the two. Similarly, when the wind disappears, the rod body 1 and the driving gear 5 are reset, and the driven gear 61 remains fixed under the action of the elastic locking member 63.

[0048] The above description is only a preferred specific embodiment of the present invention. It is impossible to list all the embodiments here, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
