Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides: A deep - water sampler, as Figures 1 - 4As shown in the figure, it includes a plexiglass barrel 1 and an elastic plate 14. A bottom cover 12 is movably installed at the bottom of the plexiglass barrel 1. A number of groups of rubber membranes 13 are installed through the bottom cover 12 with equal arcs. A sealing ring sleeve 15 is installed at the bottom of the bottom cover 12. A magnet 16 is fixedly installed on one side of the outer arc surface of the bottom cover 12. The top of the plexiglass barrel 1 is movably covered with a plexiglass top cover 18. The plexiglass top cover 18 and the bottom cover 12 are connected by a steel wire 17. A deep water locator 27 is installed on the upper surface of the plexiglass top cover 18. A locking sleeve 22 is sleeved and installed on the upper part of the outer arc surface of the plexiglass barrel 1. A lifting frame 23 is fixedly installed on the outside of the locking sleeve 22. A group of return springs 26 are fixedly installed on one side inside the lifting frame 23. One end of the return spring 26 is connected to the plexiglass top cover 18. A positioning block 9 is installed on the inner wall of the plexiglass barrel 1. The top end of the elastic plate 14 is inserted and installed with the positioning block 9. When collecting water samples from deep water, because the chain 25 is not vertically downward, there will be an error in the water depth. Through the set deep water locator 27, water quality samples at the expected depth can be collected more accurately.

[0025] Preferably, a copper ring 2 is fixedly sleeved and installed on the lower part of the outer arc surface of the plexiglass barrel 1. A group of valve bodies 3 are fixedly installed on the outside of the copper ring 2. The output end of the valve body 3 is hermetically connected and installed with a rubber tube 4. A filter screen 6 is adhesively penetrated and installed on the inner wall of the plexiglass barrel 1 corresponding to the position of the valve body 3. The copper ring 2 sleeved on the outer arc surface of the plexiglass barrel 1 is used to increase the overall weight of the device, so that the device can dive to the specific sampling position more quickly. The valve body 3 and the rubber tube 4 installed on one side of the copper ring 2 can ensure that the water inside the device is smoothly sent out to the inside of the container after the device finishes taking water, reducing the influence of the external environment on the deep water collected. The filter screen 6 provided on the inner wall of the plexiglass barrel 1 corresponding to the valve body 3 can filter the taken deep water body to prevent sundries from entering the inside of the valve body 3 and the rubber tube 4, causing the device to be blocked.

[0026] Furthermore, a plastic sealing ring 5 is sleeved and installed on the outer arc surface of the plexiglass barrel 1 below the valve body 3. A magnet 7 is embedded and installed on the inner wall of the plexiglass barrel 1 corresponding to the position of the plastic sealing ring 5. The plastic sealing ring 5 and the magnet 7 installed at the bottom of the plexiglass barrel 1 can cooperate with the bottom cover 12, the sealing ring sleeve 15 and the magnet 16 to limit the bottom cover 12. When the device is put into the deep water area, due to the influence of water pressure, the magnet 16 is separated from the magnet 7, so as to better ensure that water enters the inside of the plexiglass barrel 1. And when collecting the device, through the water pressure inside the plexiglass barrel 1, the reset of the bottom cover 12 is completed. The set plastic sealing ring 5 is locked from the bottom of the plexiglass barrel 1, and the plastic sealing ring 5 limits the sealing ring sleeve 15 to prevent the sealing ring sleeve 15 from detaching from the inside of the plexiglass barrel 1.

[0027] Furthermore, several groups of reinforcing columns 8 are equiangularly embedded and installed inside the plexiglass barrel 1. A support seat 10 is installed above the positioning block 9 on the inner wall of the plexiglass barrel 1. A thermometer 11 is inserted inside the support seat 10. The reinforcing columns 8 arranged inside the plexiglass barrel 1 are used to enhance the service strength of the plexiglass barrel 1, avoiding the possibility of overall deformation of the plexiglass barrel 1 when the pressure is relatively strong. The support seat 10 installed inside the plexiglass barrel 1 positions the thermometer 11. The thermometer 11 is used to measure the water temperature inside the plexiglass barrel 1 in real time, making the sampling information clearer.

[0028] It should be noted that a steel wire 17 is fixedly installed at the center of the upper surface of the bottom cover 12. The outer arc surface of the sealing ring sleeve 15 is movably installed in contact with the inner wall of the plexiglass barrel 1. A magnet 16 is embedded in the outer arc surface of the sealing ring sleeve 15, and the magnet 16 is movably adsorbed with the magnet 7. The provided steel wire 17 is used to connect the bottom cover 12 and the steel wire 17, which can prevent the bottom cover 12 or the resin top cover 18 from detaching from the device alone and being unable to be reset. The rubber film 13 installed in the middle of the bottom cover 12 can change the usage state of the bottom cover 12, preventing water leakage and reducing the pressure on the bottom cover 12. The provided elastic plate 14 positions the bottom cover 12, enabling the bottom cover 12 to be lifted by the water pressure and ensuring the quick reset of the bottom cover 12 when collecting the device.

[0029] Specifically, a rubber sealing rubber tube 19 is installed at the bottom of the resin top cover 18. The outer arc surface of the rubber sealing rubber tube 19 is movably fitted and inserted into the inner wall of the plexiglass barrel 1. A locking head 20 is installed through the center of the resin top cover 18. The end of the steel wire 17 extends into the locking head 20 and is locked and installed. A positioning seat 21 is fixedly installed on one side of the upper surface of the resin top cover 18. The rubber sealing rubber tube 19 installed at the bottom of the resin top cover 18 can improve the sealing performance of the plexiglass barrel 1 during use, enabling the device to better withstand the water pressure, causing the bottom cover 12 and the resin top cover 18 to separate. The locking head 20 installed at the top of the resin top cover 18 locks the end of the steel wire 17, making the connection between the bottom cover 12 and the resin top cover 18 more stable.

[0030] In addition, a connection head 24 is fixedly installed in the middle of the outer arc surface of the lifting frame 23. A chain 25 is locked and installed inside the connection head 24. Another group of positioning seats 21 is fixedly installed on one side of the inner wall of the lifting frame 23. One end of the return spring 26 is inserted into the positioning seat 21 installed on the inner wall of the lifting frame 23, and the other end of the return spring 26 is inserted into the positioning seat 21 installed at the top of the resin top cover 18. The provided connection head 24 and chain 25 enable the device to be better put into use in water, preventing the device from being lost inside the water. The provided positioning seat 21 positions the return spring 26, enabling the resin top cover 18 to be pressured by the return spring 26 and quickly reset the resin top cover 18.

[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
