[0002] Taking the water system as a whole, according to the geographical distribution of towns and industrial and mining enterprises along the water system, as well as the self-purification ability, pollution carrying capacity and pollution status of the water system, comprehensive prevention and control measures are taken to prevent water pollution. It includes various engineering and technical means and management measures, and specifically has the characteristics of integrity, comprehensiveness and regionality. During the prevention and control process, it is necessary to sample the water flow, and at this time, a sampling device is needed, and a water quality sampling device for water environmental pollution prevention and control is required.

[0003] In the prior art, a water quality sampling device for water environmental pollution prevention and control generally includes a pull rope. One end of the pull rope is fixedly connected with a sampling cylinder. The staff holds the pull rope, then places the sampling cylinder in the water. After the water enters the sampling cylinder, the pull rope is pulled to take out the sampling cylinder.

[0004] However, when the above device is used, when the sampling cylinder is in the water, impurities and pollutants in the water will enter the sampling cylinder, and the staff still needs to clean the impurities in the sampling cylinder, which increases the labor intensity of the staff. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a water quality sampling device for water environmental pollution prevention and control. Its advantages are: it can avoid large impurities from entering the sampling cylinder, and achieve the effect of reducing the labor intensity of the staff.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A water quality sampling device for water environmental pollution prevention and control includes a grip rod. One side of the grip rod is fixedly connected with a connecting rod. The connecting rod is in an L-shaped structure. One side bottom of the connecting rod is fixedly connected with a sampling cylinder. The bottom outer wall of the sampling cylinder is provided with a water inlet. The inner wall of the water inlet is covered with a sealing plate. One side of the sealing plate is provided with a connecting mechanism. The bottom of the inner wall of the water inlet is fixedly connected with a filter screen plate. The filter screen plate is located below the sealing plate. A cleaning mechanism is arranged at the bottom of the sampling cylinder.

[0008] Through the above technical solutions: When in use, holding the grip rod can press the sampling cylinder fixedly connected to the connecting rod into the water, so that water will not enter from the top of the sampling cylinder. When the sampling cylinder is at the position where sampling is required, rotate the rotating block. The rotation of the rotating block can cause the threaded rod to rotate. The rotation of the threaded rod can apply a force to the adjusting block. The adjusting block can slide on the inner wall of the adjusting groove under the force. The movement of the adjusting block can separate the sealing plate from the water inlet. The impurities in the water can enter the sampling cylinder through the water inlet after being filtered by the filter screen plate. After enough water is obtained, reverse the above operations. When cleaning the filter screen plate, hold the grip rod and make the connecting block close to the ground, and shake it up and down reciprocally. The contact between the connecting block and the ground and the elastic force of the connecting spring can prevent the device from generating rigid vibrations, and at the same time, the impurities at the bottom of the filter screen plate can be removed. In addition, the linear movement of the connecting block in the connecting groove can make the sealing plate tightly clamped and not deformed. The sealing plate is affected by its own gravity, and a light material can be used to achieve force balance, which can make the water filtered by the filter screen plate enter the bucket. And after sampling, shaking the sampling cylinder can clean the filter screen plate, which is also convenient for the user to use. Compared with directly adding rod members on the sealing plate, the sealing plate can be closely attached to the sampling cylinder, the sampling cylinder can be stably sealed, and thus it is convenient for the user to use. In actual use, a sampling cylinder with a certain wall thickness can be made to facilitate the movement of the connecting block. Therefore, larger impurities can be prevented from entering the sampling cylinder, achieving the effect of reducing the labor intensity of the staff.

[0009] The present utility model is further configured such that the cleaning mechanism includes a plurality of connecting blocks evenly distributed. The connecting blocks are arranged around the filter screen plate. The bottom of the sampling cylinder is provided with connecting grooves corresponding to the connecting blocks one by one.

[0015] The utility model is further arranged such that the bottom inner wall of the adjustment groove is rotatably connected with a threaded rod through a bearing, and the threaded rod is threadedly connected with the adjustment block.

[0016] Through the above technical solution: The arrangement of the threaded rod enables the adjustment block to slide on the inner wall of the adjustment groove when rotating.

[0017] The utility model is further arranged such that the top of the threaded rod is fixedly connected with a rotating block.

[0018] Through the above technical solution: The arrangement of the rotating block enables the threaded rod to rotate when rotating.

[0019] The utility model is further arranged such that a sealing gasket surrounding the sealing plate is fixedly connected to the circumference of the sealing plate. The sealing gasket is made of rubber and is in contact with the water inlet.

For this water quality sampling equipment for water environmental pollution prevention and control, when in use, holding the grip rod can press the sampling cylinder fixedly connected to the connecting rod into the water, preventing water from entering through the top of the sampling cylinder. When the sampling cylinder is at the position where sampling is required, rotate the rotating block. The rotation of the rotating block can cause the threaded rod to rotate. The rotation of the threaded rod can apply a force to the adjustment block, and the adjustment block can slide on the inner wall of the adjustment groove under the force. The movement of the adjustment block can separate the sealing plate from the water inlet. The impurities in the water can enter the sampling cylinder through the water inlet after being filtered by the filter screen plate. After obtaining enough water, reverse the above operations.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0031] The embodiments of this patent will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation of this patent.

[0032] Referring to Figures 1-3 , a water quality sampling equipment for preventing and controlling water environment pollution includes a grip rod 1. One side of the grip rod 1 is fixedly connected with a connecting rod 2. The connecting rod 2 is in an L-shaped structure. The bottom of one side of the connecting rod 2 is fixedly connected with a sampling cylinder 3. The outer wall of the bottom of the sampling cylinder 3 is provided with a water inlet 4. The inner wall of the water inlet 4 is covered with a sealing plate 9. A connecting mechanism is arranged on one side of the sealing plate 9. The bottom of the inner wall of the water inlet 4 is fixedly connected with a filter screen plate 5. The filter screen plate 5 is located below the sealing plate 9. A cleaning mechanism is arranged at the bottom of the sampling cylinder 3.

[0033] It should be noted that in this embodiment, the cleaning mechanism includes a number of evenly distributed connecting blocks 8. The connecting blocks 8 are arranged around the filter screen plate 5. A connecting groove 6 corresponding to each connecting block 8 is opened at the bottom of the sampling cylinder 3. A connecting spring 7 is fixedly connected to the inner wall of the top of the connecting groove 6. The connecting spring 7 is fixedly connected to the connecting block 8. The sampling cylinder 3 can be moved up and down through the sliding of the connecting block 8 on the inner wall of the connecting groove 6, and the bottom of the filter screen plate 5 can be cleaned.

[0034] Furthermore, in this embodiment, the inner wall cross-section of the water inlet 4 is in a T-shaped structure, and the sealing plate 9 is also in a T-shaped structure. The inner wall cross-section of the T-shaped water inlet 4 can increase the flow rate of the water, enabling the water to enter the sampling cylinder 3 more quickly. The sealing plate 9 can increase the contact area with the sampling cylinder 3, preventing water leakage.

[0035] The connecting mechanism includes an adjusting block 11 fixedly connected to one side of the sealing plate 9. An adjusting groove 10 is opened on the inner wall of one side of the sampling cylinder 3. A sliding fit is formed between the inner wall of the adjusting groove 10 and the adjusting block 11. The adjusting block 11 can slide on the inner wall of the adjusting groove 10, facilitating the movement of the sealing plate 9.

[0036] The inner wall of the bottom of the adjusting groove 10 is rotatably connected to a threaded rod 12 through a bearing. The threaded rod 12 is threadedly connected to the adjusting block 11. The adjusting block 11 can slide on the inner wall of the adjusting groove 10 when the threaded rod 12 rotates.

[0037] The top of the threaded rod 12 is fixedly connected to a rotating block 13. The threaded rod 12 can be rotated by rotating the rotating block 13.

[0038] A sealing gasket 14 surrounding the sealing plate 9 is fixedly connected to the circumference of the sealing plate 9. The sealing gasket 14 is made of rubber and is in contact with the water inlet 4. The sealing gasket 14 can reduce the gap between the sealing plate 9 and the water inlet 4, preventing water leakage.

[0039] A cavity 15 is opened in the sealing gasket 14. The cavity 15 facilitates the deformation of the sealing gasket 14, further preventing water leakage.

[0040] Working principle: When in use, holding the grip rod 1 can press the sampling cylinder 3 fixedly connected to the connecting rod 2 into the water, so that water will not enter from the top of the sampling cylinder 3. When the sampling cylinder 3 is at the position where sampling is required, rotate the rotating block 13. The rotation of the rotating block 13 can cause the threaded rod 12 to rotate. The rotation of the threaded rod 12 can exert a force on the adjusting block 11. The adjusting block 11 can slide on the inner wall of the adjusting groove 10 under the force. The movement of the adjusting block 11 can separate the sealing plate 9 from the water inlet 4. The impurities in the water can enter the sampling cylinder 3 through the water inlet 4 after being filtered by the filter screen plate 5. After enough water is obtained, reverse the above operations. When cleaning the filter screen plate 5, hold the grip rod 1 and make the connecting block 8 approach the ground, and shake it up and down reciprocally. The contact between the connecting block 8 and the ground and the elastic force of the connecting spring 7 can prevent the equipment from generating rigid vibrations, and at the same time, the impurities at the bottom of the filter screen plate 5 can be removed. In addition, the linear movement of the connecting block 8 in the connecting groove 6 can make the sealing plate 9 tightly clamped and not deformed. The sealing plate 9 is affected by its own gravity. Using a lightweight material can achieve force balance, allowing the water filtered by the filter screen plate 5 to enter the bucket. And after sampling is completed, shaking the sampling cylinder 3 can clean the filter screen plate 5, which is also convenient for the user to use. Compared with directly adding rod members to the sealing plate 9, the sealing plate 9 can be closely attached to the sampling cylinder 3, making the sampling cylinder 3 sealed stably, and thus facilitating the user to use. In actual use, a sampling cylinder 3 with a certain wall thickness can be made to facilitate the movement of the connecting block 8. Therefore, larger impurities can be prevented from entering the sampling cylinder 3, achieving the effect of reducing the labor intensity of the staff.
