[0024] For the embodiments, please refer to Figures 1-4 The present utility model provides a technical solution:
[0025] An auxiliary sampling device for a small river in environmental surface water monitoring, comprising a sampling water bucket 1. A chassis 2 is provided at the bottom of the sampling water bucket 1. Screws 3 are provided at the top of the chassis 2 and on the left and right sides of the sampling water bucket 1. Counterweight blocks 4 are symmetrically installed on the upper side of the chassis 2. Through holes 5 are provided on the counterweight blocks 4 corresponding to the screws 3. Nuts 6 are sleeved on the outer wall of the screws 3 and above the counterweight blocks 4. First hanging rings 7 are symmetrically provided at the top of the sampling water bucket 1. A connecting rope 8 is tied to the upper side of the first hanging rings 7. A top plate 9 is provided at the top of the connecting rope 8. A water inlet hole 10 is provided in the middle of the top of the sampling water bucket 1. A hole plug 11 is provided inside the water inlet hole 10. A connecting rod 12 is provided between the hole plug 11 and the top plate 9. A second hanging ring 13 is provided in the middle of the top of the top plate 9. A pulling rope 14 is tied to the upper side of the second hanging ring 13.
[0026] In this embodiment, the screw rod 3 passes through the through hole 5, and the connection mode between the screw rod 3 and the through hole 5 is a sliding connection. The outer shape structure of the counterweight 4 is designed as a semi-circular ring structure. The connection mode between the nut 6 and the screw rod 3 is a threaded connection. The outer shape structure of the vertical cross-section of the hole plug 11 is designed as an inverted T-shaped structure. The connection mode between the hole plug 11 and the through hole 5 is a sliding connection. By setting the chassis 2, the screw rod 3, the counterweight 4, the through hole 5, and the nut 6, the weight of the sampling water bucket 1 can be increased, so as to facilitate sinking the sampling water bucket 1 into the water. The first hanging ring 7, the connecting rope 8, the top plate 9, the hole plug 11, the connecting rod 12, the second hanging ring 13, and the pulling rope 4 can open the through hole 10 when the sampling water bucket 1 is not pulled up, and block the through hole 10 when the sampling water bucket 1 is pulled up. Through the above design, it is convenient to carry out water sampling operations in small rivers.
[0027] The working process of the present utility model is as follows: First, the counterweight 4 is sleeved on the screw rod 3 through the through hole 5, and then the nut 6 is screwed onto the screw rod 3. At this time, the counterweight 4 is installed on the chassis 2. Then, the sampling water bucket 1 is placed in a small river. At this time, the hole plug 11 is located below the through hole 5. Then, water will enter the sampling water bucket 1 through the through hole 5. After the water in the sampling water bucket 1 is full, the top plate 9 is pulled upward through the pulling rope 14. At this time, the connecting rod 12 will also pull the hole plug 11 upward. Then, the hole plug 11 will block the through hole 5 until the sampling water bucket 1 is pulled out of the water surface, thus completing the water sampling operation. By setting the chassis 2, the screw rod 3, the counterweight 4, the through hole 5, and the nut 6, the weight of the sampling water bucket 1 can be increased, so as to facilitate sinking the sampling water bucket 1 into the water. The first hanging ring 7, the connecting rope 8, the top plate 9, the hole plug 11, the connecting rod 12, the second hanging ring 13, and the pulling rope 4 can open the through hole 10 when the sampling water bucket 1 is not pulled up, and block the through hole 10 when the sampling water bucket 1 is pulled up. Through the above design, it is convenient to carry out water sampling operations in small rivers.
[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
