Technical Field

[0001] The utility model relates to the technical field of water quality sampling devices, and particularly relates to a water quality monitoring stratified sampling device. Background Art

[0002] The water quality monitoring stratified sampling device is a device used for environmental protection and water quality monitoring. It can automatically sample the water quality at different water depths without using sensors and solenoid valves. This device mainly solves some deficiencies in the existing water quality monitoring technology, such as cumbersome operation, low efficiency, inaccurate water quality monitoring data, etc. The stratified sampling device adopts sampling cavities arranged in an array, which can be automatically opened according to the water pressure at different water depths.

[0003] The structure of the existing water quality monitoring stratified sampling device is too complex. Especially, the opening and closing of the sampling cavity need to be controlled by components such as electric push rods, and each sampling cavity needs to be correspondingly installed with an electric push rod structure. However, the volume structure of the water quality monitoring stratified sampling device is limited, which leads to overcrowding of the internal components, and thus it is not convenient for later maintenance.

[0004] Therefore, it is necessary to invent a water quality monitoring stratified sampling device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water quality monitoring stratified sampling device to solve the above deficiencies in the technology.

Each guiding block corresponds to the top position of each water sampling tank. The other end of each connecting rod slides through the front end of the guiding block.

[0010] As a preferred solution of the present utility model, a support frame is fixedly installed above the interior of the water collection tank. A spring is fixedly installed above the support frame. The upper end of the spring is fixedly connected to the bottom of the sealing cover. The other end of the connecting rod is threadedly connected to the top of the sealing cover.

[0011] As a preferred solution of the present utility model, a base is fixedly installed at the bottom of the upper mounting plate above. The motor is installed inside the base. A protective cover is fixedly installed at the top of the upper mounting plate by bolts. A through hole is opened at the vertical center of the protective cover. The output end of the motor penetrates through the through hole at the center of the protective cover.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] The present utility model provides a water quality monitoring stratified sampling device as Figures 1-5 shown, which includes a mounting bracket 1. Mounting plates 9 are fixedly installed above and below the mounting bracket 1. A plurality of water collection tanks 2 are uniformly distributed in a circular array around the outer circumferences of the two mounting plates 9. A ring-shaped frame 5 is provided at the top of the upper mounting plate 9, and a wedge block 6 is fixedly installed on one side of the top of the ring-shaped frame 5;

[0026] A motor 3 is fixedly installed inside the upper mounting plate 9. A shaft rod is fixedly installed at the bottom of the ring-shaped frame 5. The output end of the motor 3 is fixedly connected to the shaft rod at the bottom of the ring-shaped frame 5;

[0027] A sealing cover 21 is covered on the top of each water collection tank 2. A connecting rod 8 is provided at the top of each water collection tank 2. The connecting rod 8 has a U-shaped structure. One end of the connecting rod 8 is located above the ring-shaped frame 5, and the other end of the connecting rod 8 corresponds to the center position of the sealing cover 21.

[0028] Further, in the above technical solution, a plurality of uniformly distributed guide blocks 7 are fixedly installed at the top of the mounting bracket 1. One end of the connecting rod 8 is limited by the guide block 7, so that the connecting rod 8 can move up and down along this direction. Each guide block 7 corresponds to the top position of each water collection tank 2, and the other end of each connecting rod 8 slidably penetrates through the front end of the guide block 7.

[0029] Furthermore, in the above technical solution, a support frame 22 is fixedly installed above the interior of the water collection tank 2. A spring 23 is fixedly installed above the support frame 22. The upper end of the spring 23 is fixedly connected to the bottom of the sealing cover 21. The other end of the connecting rod 8 is threadedly connected to the top of the sealing cover 21, thereby facilitating the connection and disassembly of the connecting rod 8 and the sealing cover 21. The spring 23 connects the sealing cover 21, enabling the sealing cover 21 to tightly cover the upper opening of the water collection tank 2.

[0030] Furthermore, in the above technical solution, a base 11 is fixedly installed at the bottom of the upper mounting plate 9. The motor 3 is installed inside the base 11. The top of the upper mounting plate 9 is fixedly installed with a protective cover 4 through bolts. The upper part of the motor 3 is covered by the protective cover 4, which plays a role in waterproofing and partitioning to protect the motor 3. A through hole is provided at the vertical center of the protective cover 4. The output end of the motor 3 passes through the through hole at the center of the protective cover 4. A sealing ring 41 is installed at the through hole position at the top of the protective cover 4. The sealing ring 41 is used to seal the through hole and the output end of the motor 3 to prevent water from entering the motor 3 through this through hole.

[0031] Furthermore, in the above technical solution, a number of evenly distributed arc-shaped notches are provided on the outer sides of the two mounting plates 9. The outer diameter of the water collection tank 2 is adapted to the arc-shaped notches on the outer sides of the mounting plates 9. A clamping ring 10 is fixedly installed at the position of the arc-shaped notch of each mounting plate 9. The clamping ring 10 is adapted to the outer diameter of the water collection tank 2. The water collection tank 2 is fixed by the clamping ring 10, improving the stability of the installation of the water collection tank 2. Compared with the existing structure using a hoop, its stability is better.

[0032] Furthermore, in the above technical solution, the notch position of the connecting rod 8 corresponds to the position of the wedge-shaped block 6. The wedge-shaped block 6 has a right trapezoidal structure, and the wedge-shaped block 6 with this structure can lift the connecting rod 8.

[0033] When the water quality monitoring stratified sampling device provided by the present utility model is in use, its working process is as follows:

[0034] A plurality of water collection tanks 2 are installed at the arc-shaped notch positions on the outer sides of the mounting plates 9 and fixed by the clamping rings 10. Then, the sealing covers 21 on the tops of each water collection tank 2 are installed properly. The front ends of each guide block 7 are inserted into the corresponding connecting rods 8, and one end below each connecting rod 8 is threadedly connected to the top end of the corresponding sealing cover 21. Then, the annular frame 5 is rotated to make the wedge-shaped block 6 rotate to the position between the two connecting rods 8. Then, the whole device is placed into the water area where sampling and detection are required.

[0035] When the device reaches a certain depth in the water area, the motor 3 is started. The motor 3 drives the annular frame 5, and the annular frame 5 drives the wedge block 6 to start rotating by a certain angle. When the wedge block 6 rotates below a connecting rod 8, the lowest point of the inclined surface of the wedge block 6 begins to contact the connecting rod 8. As the wedge block 6 continues to rotate by a certain angle under the control of the motor 3, when the connecting rod 8 immediately contacts the highest point of the inclined surface of the wedge block 6, since the position height of the wedge block 6 is certain, the connecting rod 8 is lifted. As the connecting rod 8 is lifted, the end of the connecting rod 8 equipped with the sealing cover 21 also rises, and then the bottom of the sealing cover 21 is separated from the upper opening of the water sampling tank 2. After that, the water source at this depth position enters the interior of the water sampling tank 2 through this opening. When a certain amount of water source is collected inside the water sampling tank 2, the motor 3 drives the annular frame 5 and the wedge block 6 to continue rotating, and the wedge block 6 is moved away from the connecting rod 8.

[0036] When the wedge block 6 leaves the position of the connecting rod 8, the connecting rod 8 loses the supporting force. Due to the influence of the buoyancy in the water on the connecting rod 8 and the sealing cover 21, they cannot fall naturally. Since the bottom of the sealing cover 21 is connected to the spring 23 inside the water sampling tank 2, under the action of the spring 23, the spring 23 restores its deformation and pulls the sealing cover 21 to cover the top opening of the water sampling tank 2 again, thus completing a water sample collection operation. After that, the device is controlled to descend to different depths in the water area, and the above operation process is repeated to complete the sampling work of water sources at different depths.

[0037] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
