Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-4 A measurement and calibration device includes a water storage tank 1 and a connection panel 2 arranged below the water storage tank 1. The water storage tank 1 is fixed to the upper end of the connection panel 2 through a connection column 3. A water pump 4 is arranged at the lower end of the water storage tank 1. The water outlet end of the water pump 4 is connected to a water outlet pipe 5. A nozzle 6 is arranged at one end of the water outlet pipe 5. Storage shells 12 are arranged on both sides of the nozzle 6. A cleaning component 7 is arranged in the nozzle 6 for cleaning particulate matter in the water to prevent it from being blocked. A connecting chamber 9 is opened in the storage shell 12. A vibration component 8 is arranged on the nozzle 6 for allowing the nozzle 6 to vibrate.

[0023] The cleaning assembly 7 includes a connecting shaft 72 rotatably arranged on the nozzle 6 and a paddle 71 fixedly installed on the upper end of the connecting shaft 72. The paddle 71 is arranged just below the water outlet and can be easily rotated. An L-shaped rod 73 is installed on the axial side wall of the connecting shaft 72. The L-shaped rod 73 fits with the bottom wall of the nozzle 6. The connecting chamber 9 is connected to the inner cavity of the nozzle 6 through the notch 74. Through the setting of the notch 74, stones can easily enter the inner cavity of the connecting chamber 9 from the notch 74.

[0024] An inclined panel 11 is fixedly installed on the side wall of the intersection of the notch 74 and the connecting chamber 9. The setting of the inclined panel 11 can further prevent stones that enter the inner cavity of the connecting chamber 9 from entering the inner cavity of the nozzle 6 again.

[0025] The vibration assembly 8 includes a connecting ring 83 fixedly mounted on the axial side wall of the connecting shaft 72 and a spring 82 sleeved on the connecting shaft 72. The L-shaped rod 73 is slidably set on the connecting shaft 72. The two ends of the spring 82 are respectively fixedly connected to the bottom wall of the connecting ring 83 and the side wall of the L-shaped rod 73. A plurality of arc-shaped spheres 81 are fixedly mounted on the bottom wall of the nozzle 6.

[0026] In this embodiment: the water to be tested is drawn from the river into the water storage tank 1. The water in the inner cavity of the water storage tank 1 will contain more impurities. Then the water pump 4 is turned on. The water pump 4 discharges the water in the water storage tank 1 to a designated position through the water outlet pipe 5 and the nozzle 6. When the water enters the inner cavity of the nozzle 6, the flow of water will drive the paddle 71 to rotate. The paddle 71 will drive the connecting shaft 72 to rotate. The connecting shaft 72 will drive the L-shaped rod 73 at the lower end to rotate. The L-shaped rod 73 will slide along the bottom wall of the nozzle 6, and the stones or sand in the water can be swept into the corresponding connecting chamber 9 through the notch 74. Through the flow of water, the stones swept into the inner cavity of the connecting chamber 9 are not It will enter the inner cavity of the nozzle 6 again, which can ensure that the nozzle 6 will not be blocked by stones and affect its discharge. At the same time, when the L-shaped rod 73 moves along the side wall of the inner cavity of the nozzle 6, it will contact the corresponding arc-shaped sphere 81. Because the L-shaped rod 73 is slidably set on the connecting shaft 72, it will slide along the arc-shaped sphere 81, and the L-shaped rod 73 will be lifted up and the spring 82 will be squeezed at the same time. When the L-shaped rod 73 is separated from the arc-shaped sphere 81, the L-shaped rod 73 will be quickly restored to the initial position by the elastic force of the spring 82. In this process, it will hit the bottom wall of the nozzle 6 to make the nozzle 6 vibrate, which can further prevent its aperture from being blocked and ensure the discharge of water.

The bottom wall of the connecting chamber 9 is provided with a plurality of water dispersion holes 104. Through the setting of the water dispersion holes 104, water can be further discharged and backflow caused by sand or stones can be prevented.

[0030] Arc-shaped rubber blocks 102 are fixedly mounted on both side walls of the sealing column 101. The arrangement of the arc-shaped rubber blocks 102 can further ensure the sealing performance between the sealing column 101 and the connecting channel 103, and will not cause water loss.

[0031] In this embodiment: after the drainage is completed, the operator can pull the sealing column 101 outward, and the sealing column 101 will slide along the connecting channel 103 until the sealing column 101 drives the arc-shaped rubber block 102 to detach from the connecting channel 103. At this time, the connecting chamber 9 can be exposed to the outside world, and the operator can easily take out the stones or sand to facilitate the next use.
