Description

Technical Field

[0001] The utility model relates to the technical field of water quality monitoring, in particular to a sampling box for monitoring points of drinking water quality. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, etc.; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides. Water quality monitoring first requires sampling of water bodies at multiple locations, and then transporting the samples to research institutions for research and analysis. During the transportation process, the samples are stored in sampling boxes.

[0003] In actual water quality monitoring, it is necessary to take samples from multiple locations in the water body, and the sample sizes required for testing different substances in the water are not the same, which leads to different specifications of sampling tubes. However, the existing sampling boxes have a small capacity and can only store a small number of samples, and can only store sampling tubes of one specification.

[0004] Based on the above situation, the utility model proposes a sampling box for drinking water quality monitoring points, which has a large capacity and can store sampling tubes of various specifications. Utility Model Content

[0005] In order to overcome the shortcomings of the existing sampling box with small capacity and single specification of sampling tubes, the utility model provides a sampling box for drinking water quality monitoring point with large capacity and capable of storing sampling tubes of various specifications.

[0006] The utility model provides a sampling box for monitoring points of drinking water quality, comprising a rounded corner frame, a rotating frame, a connecting ring, an insert rod, a large circular hole seat, a small circular hole seat and a fixing mechanism, wherein the rounded corner frame is rotatably connected to a pair of rotating frames, the rotating frame is fixedly connected to a pair of connecting rings vertically distributed up and down, the pair of connecting rings are slidably connected to the insert rod, the rounded corner frame is fixedly connected to the large circular hole seats vertically distributed, a fixing mechanism is arranged inside the large circular hole seat, and the rotating frame is fixedly connected to the small circular hole seats vertically distributed.

[0007] As an improvement of the above solution, the fixing mechanism includes a moving block and a reset spring, the large circular hole seat is slidably connected with a pair of axially distributed moving blocks, and a reset spring is fixed between the moving block and the large circular hole seat.

[0008] As an improvement of the above scheme, it also includes connecting pipes and fans. The rounded corner frame is fixedly connected with connecting pipes distributed vertically up and down. The rounded corner frame is fixedly connected with fans distributed vertically up and down. The fans are connected with adjacent connecting pipes.

[0009] As an improvement of the above scheme, it also includes a connecting frame, a wheel set and a long rod. The rounded frame is fixedly connected to the connecting frame, the connecting frame is fixedly connected to the long rod, and the connecting frame is rotatably connected to a pair of wheel sets distributed longitudinally front and back.

[0010] As an improvement to the above solution, a pair of handles are fixedly connected to the front sides of the paired rotating frames to facilitate user gripping.

[0011] As an improvement of the above solution, there are threads on the long rod to increase the friction between the hand and the long rod to prevent the long rod from slipping out of the hand.

[0012] The utility model has the following advantages: 1. The utility model increases the capacity of the sampling box through components such as the large round hole seat and the small round hole seat, and can store sampling tubes of various specifications, thereby increasing the versatility of the sampling box.

[0013] 2. The utility model uses components such as fans and connecting pipes to keep samples at a suitable temperature during long-term transportation, thereby preventing sample deterioration from affecting test results. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0021] Example 1

[0022] A sampling box for monitoring drinking water quality, such as Figure 1-Figure 3 As shown, it includes a rounded corner frame 1, a rotating frame 2, a connecting ring 201, an insert rod 3, a large circular hole seat 4, a small circular hole seat 5 and a fixing mechanism. The left and right parts of the front side of the rounded corner frame 1 are rotatably connected to the rotating frame 2. The front sides of the two rotating frames 2 that are close to each other are fixedly connected with three groups of connecting rings 201 distributed vertically up and down, wherein each group of connecting rings 201 includes two connecting rings 201, and the four connecting rings 201 on the same horizontal plane are slidably connected with the insert rod 3, and the insert rod 3 is used to limit the rotating frame 2. The inside of the rounded corner frame 1 is fixedly connected with a large circular hole seat 4 distributed vertically, and the inside of the large circular hole seat 4 is provided with a fixing mechanism for fixing the sampling tube, and the inside of the rotating frame 2 is fixedly connected with a small circular hole seat 5 distributed vertically, and the large circular hole seat 4 and the small circular hole seat 5 are used to store sampling tubes of different specifications.

[0023] like Figure 3 As shown, the fixing mechanism includes a moving block 6 and a reset spring 7. Five pairs of axially distributed moving blocks 6 are slidably connected inside the large circular hole seat 4. A reset spring 7 is fixed between the moving block 6 and the large circular hole seat 4. The moving block 6 has an arc surface for fitting and clamping the sampling tube.

[0024] like Figure 4 and Figure 5 As shown, it also includes a connecting frame 10, a wheel set 11 and a long rod 12. The connecting frame 10 is fixedly connected to the rear side of the rounded frame 1, and the long rod 12 is fixedly connected to the top of the connecting frame 10. There are threads on the surface of the long rod 12 for increasing the friction between the hand and the long rod 12. The front and rear sides of the bottom of the connecting frame 10 are rotatably connected with the wheel set 11 which is symmetrically distributed on the left and right.

[0025] like Figure 1 As shown, the front sides of the paired rotating frames 2 are fixedly connected with left-right symmetrical handles for users to grasp conveniently.

[0026] When the researcher wants to store the sampling tube after sampling, he first pulls the rod 3 to the left until the rod 3 is separated from the connecting ring 201 on the right, and then pulls the handle forward to drive the paired rotating frames 2 to rotate forward. Then, according to the specifications of the sampling tube, the sampling tube is placed in the small round hole seat 5 and the large round hole seat 4 respectively. When the sampling tube in the large round hole seat 4 is placed, the paired moving blocks 6 will be squeezed to both sides, so that the paired moving blocks 6 move backwards, and the reset spring 7 is compressed. After the sampling tube is placed, the paired moving blocks 6 are pressed against the reset spring 7. 7 will clamp and fix the sampling tube. If the researcher takes out the sampling tube, the paired moving blocks 6 will move toward each other and return to their original positions under the action of the reset spring 7. After the sampling tube is stored, the paired rotating frames 2 are rotated in the opposite direction to reset the rotating frames 2, and then the insertion rod 3 is pushed to the right to make the insertion rod 3 pass through the connecting ring 201 on the right side to lock the rotating frame 2. When the researcher wants to move the rounded corner frame 1 and the rotating frame 2, the long rod 12 can be pushed to drive the wheel group 11 to rotate through the connecting frame 10 to drive the rounded corner frame 1 and the rotating frame 2 to move.

[0027] Example 2

[0028] On the basis of Example 1, Figure 4 and Figure 5 As shown, it also includes a connecting pipe 8 and a fan 9. The rear side of the rounded corner frame 1 is fixedly connected to a connecting pipe 8 distributed vertically up and down. The rear side of the rounded corner frame 1 is fixedly connected to a fan 9 distributed vertically up and down. The fan 9 is connected to the adjacent connecting pipe 8. The fan 9 is used to adjust the temperature inside the rounded corner frame 1 and the rotating frame 2.

[0029] When the samples are transported for a long time, researchers can start the fan 9, and the air enters the connecting tube 8 through the fan 9 and then sprays out from the multiple small holes of the connecting tube 8 to adjust the temperature inside the rounded corner frame 1 and the rotating frame 2, so as to keep the samples at a suitable temperature and prevent the samples from deteriorating and affecting the test results.

[0030] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
