[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] See also Figures 1-4, the embodiment of the utility model provides a technical solution: a sample delivery device for environmental analysis, including a bracket plate 1, a bottle pushing motor support seat 2, a double-nut ball screw 3, a lifting well slider connector 4, an elastic coupling 5, a bottle pushing motor fixing seat 6, a driving motor 7, a sample toggle plate 8 and a sample moving bracket 9;

[0021] The problem is solved by providing a vertical groove 15 on the surface of the bracket plate 1, and the vertical groove 15 is in a Z-shaped structure. The bottle pushing motor support seat 2 is installed at the top of the front end of the bracket plate 1, and the bottle pushing motor fixing seat 6 is installed at the bottom of the front end of the bracket plate 1. The drive motor 7 is installed at the bottom of the bottle pushing motor fixing seat 6, and the double-nut ball screw 3 is installed at the top driving end of the drive motor 7, and the other end is installed at the bottom of the bottle pushing motor support seat 2 through a ball bearing. The elastic coupling 5 is installed between the double-nut ball screw 3 and the drive motor 7, and the lifting well slider connector 4 is provided with a group, and a group of the lifting well slider The connecting piece 4 is sleeved on the double-nut ball screw 3 in a row and equidistant manner. The sample toggle plate 8 and the sample moving bracket 9 are respectively installed at the rear end of a group of the lifting well slider connecting pieces 4. The middle sections of the sample toggle plate 8 and the sample moving bracket 9 are located in the vertical groove 15. When in use, the driving motor 7 (power device) drives the double-nut ball screw 3 to rotate, so that the sample toggle plate 8 and the sample moving bracket 9 installed on the lifting well slider connecting piece 4 move up and down synchronously along the vertical groove 15 of the bracket plate 1. Since the vertical groove 15 is irregular, its up and down movement route is a broken line, thereby driving the sample bottle 10 to deliver the sample.

[0022] Furthermore, a sample sleeve cup 11 is provided at the rear end of the sample moving bracket 9, a sample bottle 10 is installed in the sample sleeve cup 11, and a rotary joint 12 is installed at the bottom of the sample sleeve cup 11, and the rotary joint 12 is for facilitating pipe drainage.

[0023] Differently, a Hall sensor fixing sheet metal 14 is installed at the rear end of the top of the bottle pushing motor fixing base 6, and a Hall sensor 13 is installed on the top of the Hall sensor fixing sheet metal 14. When the Hall sensor 13 below senses the sample moving bracket 9 equipped with a magnet, the sample shifting plate 8 and the sample moving bracket 9 are separated at a large angle and no longer overlap up and down, which makes it convenient for the sample sleeve cup 1 installed on the sample moving bracket 9 to take and place the sample bottle 10.

[0024] Working principle: During operation, the driving motor 7 (power device) drives the double-nut ball screw 3 to rotate, so that the sample shifting plate 8 and the sample moving bracket 9 installed on the lifting well slider connector 4 move up and down synchronously along the vertical groove 15 of the bracket plate 1. Since the vertical groove 15 is irregular, its up and down movement route is a broken line. When the Hall sensor 13 below senses the sample moving bracket 9 equipped with a magnet, the sample shifting plate 8 and the sample moving bracket 9 are separated at a large angle and no longer overlap up and down, which is convenient for the sample sleeve cup 1 installed on the sample moving bracket 9 to take and place the sample bottle 10. When the sample shifting plate 8 and the sample moving bracket 9 move synchronously to the upper longer straight vertical groove 15, they overlap up and down. When they reach the appropriate distance, the sample bottle 10 is injected with a needle and the bottle is pushed to remove the needle. These injection operations are linked with other devices.

[0025] The utility model includes 1, a bracket plate; 2, a bottle pushing motor support seat; 3, a double-nut ball screw; 4, a lifting well slider connector; 5, an elastic coupling; 6, a bottle pushing motor fixing seat; 7, a driving motor; 8, a sample toggle plate; 9, a sample moving bracket; 10, a sample bottle; 11, a sample sleeve cup; 12, a rotary joint; 13, a Hall sensor; 14, a Hall sensor fixing sheet metal; 15, a vertical slot. All the components are universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. The utility model solves the problem that the existing environmental analysis equipment adjusts the height of the sample bottle manually, and the steps for adjusting the sample bottle are cumbersome, and the stability is insufficient and the adjustment efficiency is low. The utility model can automatically adjust and deliver the samples through the combination of the above components, which further improves the efficiency of sample delivery by the staff and can also improve the stability of sample delivery.

[0026] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0027] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
