Description

Technical Field

[0001] This utility model relates to the field of hydrological survey and sampling technology, and in particular to a water quality sampling rack for hydrological survey. Background Technology

[0002] In hydrological surveys, water quality sampling is a crucial step in obtaining water environment data. The water quality sampling rack, as the core sampling equipment, directly impacts sampling efficiency and data accuracy. Currently, existing sampling racks have a fixed number of sampling mechanisms, which cannot be flexibly increased or decreased according to actual survey needs. This results in limited coverage for a single sampling operation, requiring multiple trips to adjust the equipment, significantly increasing the labor intensity and time cost of fieldwork. Furthermore, field surveys often require simultaneous water sampling at different locations and depths within the same cross-section to comprehensively reflect the water quality distribution. However, existing sampling racks mostly have fixed installation designs. Adjusting the sampling position or depth requires staff to repeatedly disassemble and reassemble the sampling components on the shore or a temporary platform. This is not only cumbersome but also susceptible to environmental factors such as muddy shorelines and water flow impacts, leading to low adjustment efficiency. Therefore, we have introduced a new water quality sampling rack for hydrological surveys. Utility Model Content

[0003] The main purpose of this utility model is to provide a water quality sampling rack for hydrological surveys, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A water quality sampling frame for hydrological surveys includes a housing. A support plate is provided at the lower right end of the housing, and a mounting frame is provided at the upper end of the support plate. A motor is fixedly installed at the middle upper end of the mounting frame, and a lead screw is fixedly installed at the output end of the motor. A mounting crossbar is movably installed on the upper outer surface of the lead screw via a movable block. The interior of the mounting crossbar is a hollow structure, and a sampling component is fixedly installed on the inner left wall of the mounting crossbar. A door is movably installed at the front end of the housing via a hinge. A battery box is provided at the upper left end of the housing, and a controller is provided at the upper end of the battery box.

[0006] Preferably, the sampling assembly includes an electric telescopic rod, the output end of which is fixedly mounted with an extension frame. The upper right side of the extension frame is provided with a T-shaped groove, which extends to the lower interior of the extension frame. The left front end of the extension frame is provided with several scale lines, and the right front end of the extension frame is provided with several threaded holes. Four sampling installation mechanisms are movably installed inside the T-shaped groove, and bolts are provided at the front ends of the four sampling installation mechanisms.

[0007] Preferably, the front ends of the four sampling mechanisms are threadedly mounted inside the corresponding threaded holes by bolts.

[0008] By adopting the above technical solution, the sampling mechanism can be moved and fixed on the extension frame.

[0009] Preferably, the integer lines among the plurality of scale lines are respectively set to correspond one-to-one with a plurality of threaded holes.

[0010] By adopting the above technical solution, it is easier to accurately control the distance between sampling points.

[0011] Preferably, the sampling installation mechanism includes a T-shaped slider, a screw hole at the center of the front end of the T-shaped slider, a mounting frame fixedly mounted on the right end of the T-shaped slider, a sampling bottle movably mounted on the center of the inner surface of the mounting frame through a mounting port, a water inlet at the center of the lower end of the sampling bottle, a control valve at the lower part of the outer surface of the water inlet, a screw threadedly mounted on the center of the right end of the mounting frame, a fixing clamp movably mounted on the left end of the screw through a movable sleeve, and a handle at the right end of the screw.

[0012] By adopting the above technical solution: the slider and the T-shaped groove cooperate to achieve stable sliding; the mounting frame and the fixing clamp cooperate to firmly hold the sampling bottle; and the control valve can flexibly control whether water enters.

[0013] Preferably, the inner surface of the fixing clip is tightly fitted to the right side of the outer surface of the sampling bottle, and the left side of the inner surface of the mounting frame is tightly fitted to the left side of the outer surface of the sampling bottle.

[0014] By adopting the above technical solution, the sampling bottle is firmly clamped from both sides, effectively preventing the sampling bottle from shaking or falling off during the sampling process.

[0015] Preferably, the clamping surface of the fixing clamp is adapted to the curvature of the outer surface of the sampling bottle.

[0016] By adopting the above technical solution, the contact area between the fixing clamp and the sampling bottle is increased, making the clamping more secure and reliable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The installation position can be flexibly adjusted by the T-shaped slider and the T-shaped groove of the extension frame. The position of each mechanism can be accurately determined by the scale line. The number can be increased or decreased according to the sampling needs. The motor drives the installation cross frame to move up and down through the lead screw, and the electric telescopic rod drives the extension frame and the installation sampling mechanism to move horizontally. The two work together to achieve precise adjustment of the water inlet in vertical height and horizontal position, and can quickly send it to the appropriate sampling depth and position in the water.

[0019] 2. The screw and hand-operated clamp, which is adapted to the curvature of the outer surface of the sampling bottle, can firmly hold the sampling bottle and prevent it from shaking and falling off during sampling. This not only meets the needs of simultaneous sampling at multiple depths and positions, but also ensures the stability of the sampling bottle during the sampling process, thereby improving the flexibility and reliability of the sampling operation.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A water quality sampling frame for hydrological survey includes a housing 1. A support plate 2 is provided at the lower right end of the housing 1. A mounting frame 3 is provided at the upper end of the support plate 2. A motor 4 is fixedly installed at the middle upper end of the mounting frame 3. A lead screw 5 is fixedly installed at the output end of the motor 4. A mounting crossbar 6 is movably installed on the upper outer surface of the lead screw 5 via a movable block. The interior of the mounting crossbar 6 is a hollow structure. A sampling component 7 is fixedly installed on the inner left wall of the mounting crossbar 6. A door 8 is movably installed at the front end of the housing 1 via a hinge. A battery box 9 is provided at the upper left end of the housing 1. A controller 10 is provided at the upper end of the battery box 9.

[0030] In this embodiment, the sampling component 7 includes an electric telescopic rod 71. An extension frame 72 is fixedly installed at the output end of the electric telescopic rod 71. A T-shaped groove 73 is provided on the upper right side of the extension frame 72. The T-shaped groove 73 extends to the lower interior of the extension frame 72. Several scale lines 74 are provided on the left front end of the extension frame 72. Several threaded holes 75 are provided on the right front end of the extension frame 72. Four sampling installation mechanisms 77 are movably installed inside the T-shaped groove 73. Bolts 76 are provided at the front ends of the four sampling installation mechanisms 77. The front ends of the sampling installation mechanisms 77 are threaded into the corresponding threaded holes 75 by bolts 76. The integer lines of the several scale lines 74 correspond one-to-one with the several threaded holes 75.

[0031] The above scheme is as follows: First, according to the sampling requirements, the four installation sampling mechanisms 77 are slid to the appropriate position in the T-shaped slide groove 73 of the extension frame 72 by means of T-shaped sliders 770. The position of each installation sampling mechanism 77 is accurately determined by the scale line 74 on the left side of the front end of the extension frame 72. Then, the bolts 76 are passed through the front end of the installation sampling mechanism 77 and threaded into the corresponding threaded hole 75 to fix the installation sampling mechanism 77.

[0032] In this embodiment, the sampling mechanism 77 includes a T-shaped slider 770. A screw hole 771 is provided at the center of the front end of the T-shaped slider 770. A mounting frame 772 is fixedly mounted on the right end of the T-shaped slider 770. A sampling bottle 773 is movably mounted on the center of the inner surface of the mounting frame 772 through a mounting port. A water inlet 774 is provided at the center of the lower end of the sampling bottle 773. A control valve 775 is provided on the lower part of the outer surface of the water inlet 774. The right end of the mounting frame 772... A screw 776 is threaded through the middle of the end. A fixing clip 777 is movably installed on the left end of the screw 776 via a movable sleeve. A handle 778 is provided on the right end of the screw 776. The inner surface of the fixing clip 777 is tightly fitted to the right side of the outer surface of the sampling bottle 773. The left side of the inner surface of the mounting frame 772 is tightly fitted to the left side of the outer surface of the sampling bottle 773. The clamping surface of the fixing clip 777 is adapted to the curvature of the outer surface of the sampling bottle 773.

[0033] With the above solution: In use, the sampling bottle 773 is placed into the mounting frame 772 through the mounting port. The handle 778 is turned to drive the screw 776 to rotate, causing the fixing clamp 777 at the left end of the screw 776 to move to the left. Since the clamping surface of the fixing clamp 777 is adapted to the curvature of the outer surface of the sampling bottle 773, and the left part of the inner surface of the mounting frame 772 is in close contact with the left part of the outer surface of the sampling bottle 773, and the inner surface of the fixing clamp 777 is in close contact with the right part of the outer surface of the sampling bottle 773, the sampling bottle 773 is securely clamped. During sampling, the electric telescopic rod 71 extends and retracts, driving the extension frame 72 and the sampling mechanism 77 to move to the sampling position. The control valve 775 on the lower part of the outer surface of the water inlet 774 is opened, and the water sample enters the sampling bottle 773 through the water inlet 774. After sampling is completed, the control valve 775 is closed.

[0034] It should be noted that this utility model is a water quality sampling frame for hydrological surveys. During use, the sampling bottle 773 is first placed into the mounting frame 772 through the mounting port. Turning the handle 778 rotates the screw 776, causing the fixing clamp 777 at the left end of the screw 776 to move to the left. Because the clamping surface of the fixing clamp 777 matches the curvature of the outer surface of the sampling bottle 773, and the left side of the inner surface of the mounting frame 772 is tightly fitted with the left side of the outer surface of the sampling bottle 773, the inner surface of the fixing clamp 777... The surface of the sampling mechanism 77 is tightly fitted to the right side of the outer surface of the sampling bottle 773, thus firmly clamping the sampling bottle 773 and preventing it from shaking or falling off during sampling. Next, according to the sampling requirements, the four sampling mechanisms 77 are slid into appropriate positions within the T-shaped grooves 73 of the extension frame 72 via T-shaped sliders 770. The position of each sampling mechanism 77 is precisely determined using the scale line 74 on the left side of the front end of the extension frame 72. Finally, bolts 76 are passed through the front end of the sampling mechanism 77 and threaded onto the corresponding... The sampling mechanism 77 is fixed in the threaded hole 75. If it is necessary to collect water at multiple different depths at the same time, the number of sampling mechanisms 77 can be increased. Then, the controller 10 controls the motor 4 to work. The output end of the motor 4 drives the lead screw 5 to rotate, so that the movable block drives the mounting frame 6 to move up and down to adjust to a suitable height. At the same time, the electric telescopic rod 71 in the sampling assembly 7 is controlled to extend and retract, so that the extension frame 72 and the sampling mechanism 77 are moved horizontally above the sampling water area. The height is then adjusted by the motor 4 so that the water inlet 774 is submerged in the water to a suitable depth. The controller 10 opens the control valve 775 on the lower part of the outer surface of the water inlet 774. The water sample enters the sampling bottle 773 through the water inlet 774. After the sampling is completed, the control valve 775 is closed. The sampling mechanism 77 is reset by the motor 4 and the electric telescopic rod 71. The sampling bottle 773 is taken out by rotating the handle 778 in the opposite direction. Then, the water in the sampling bottle 773 is poured into the storage bottle and placed inside the box 1 for storage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
