The outside of the piston rod of the hydraulic cylinder 7 is covered with a guide tube 6, and a discharge trough 701 is provided on the piston rod. The head of the piston rod corresponds to the feeding hole 403. The head of the piston rod can be inserted into the feeding hole 403 and then push open the flange cover 3. The discharge trough 701 is used to feed inside the high-pressure chamber 4.

[0037] A discharge groove 701 is provided at the head of the piston rod, and a No. 2 sealing groove 704 is provided on the piston rod behind the discharge groove 701. A No. 2 sealing ring 702 is installed in the No. 2 sealing groove 704. An upwardly protruding guide tenon 703 is provided at the tail of the piston rod; a guide groove 601 is provided on the guide cylinder 6, and the guide tenon 703 cooperates with the guide groove 601.

[0038] The guide groove 601 is formed by connecting a straight groove and a circular arc groove.

[0039] The guide tenon 703 moves in the guide groove 601 as the piston rod extends and contracts, thereby realizing the rotation of the piston rod.

[0040] Four guide rod mounting holes 401 are provided on the inner surface of the boss in the circumferential direction.

[0041] A nut is provided at the end of each guide rod 1 , and the nut abuts against the return spring 2 .

[0042] The outer diameter of the flange cover 3 is the same as the outer diameter of the boss.

[0043] Four fixing holes 404 are provided in the circumferential direction of the outer surface of the boss.

[0044] The hydraulic cylinder fixing rod 5 is connected to the flange of the guide cylinder 6 through a nut, and the hydraulic cylinder fixing rod 5 is connected to the cylinder body of the hydraulic cylinder 7 through a nut.

[0045] The axes of the hydraulic cylinder 7 and the guide cylinder 6 are on the same straight line.

[0046] The discharge trough 701 is a square notch, which is convenient for the release of deep-sea organisms.

[0047] The specific structure and function of the hyperbaric chamber feeding device of the present invention are as follows:

[0048] It mainly includes a high-pressure chamber 4, a hydraulic cylinder 7, a guide cylinder 6, a flange cover 3, a return spring 2, a guide rod 1 and a hydraulic cylinder fixing rod 5.

[0049] A boss is located at the feed point on the bulkhead of the high-pressure chamber 4. A feed hole 403 is located in the center of the boss, penetrating the high-pressure chamber wall. The inner surface of the boss is provided with multiple guide rod mounting holes 401, a No. 1 sealing groove, and a No. 1 sealing ring 402. The outer surface of the boss is provided with multiple fixing holes 404 for mounting the hydraulic cylinder fixing rod 5.

[0050] A discharge trough 701, a No. 2 sealing groove 704, a No. 2 sealing ring 702, and a guide tenon 703 are provided on the piston rod of the hydraulic cylinder 7. The discharge trough 701 is used to place the required delivery materials. The No. 2 sealing groove 704 and the No. 2 sealing ring 702 are used to ensure that the high-pressure water in the high-pressure chamber 4 will not leak through the feeding hole 403 during the feeding process.

[0051] A guide groove 601 is provided on the guide cylinder 6. The guide tenon 703 moves in the guide groove 601 as the piston rod extends and retracts, and realizes the rotation of the piston rod, thereby achieving the effect of turning over and feeding the discharge chute 701 in the high-pressure chamber 4.

[0052] The hydraulic cylinder 7 and the guide cylinder 6 are mounted on the outer surface of the high-pressure chamber 4 through a plurality of hydraulic cylinder fixing rods 5 , and the axis of the hydraulic cylinder 7 and the axis of the guide cylinder 6 are on the same straight line.

[0053] The flange cover 3 is fixed to the feeding hole 403 on the inner surface of the high-pressure chamber 4 through the guide rod 1. The reset spring 2 is installed on the guide rod 1. After the feeding is completed, the reset spring 2 pushes the flange cover 3 to fit tightly against the No. 1 sealing groove and the No. 1 sealing ring 402 to achieve the sealing of the feeding hole 403.

[0054] In the actual working process, the installation is completed through the following steps:

[0055] Step 1: Place the flange cover 3 close to the feeding hole 403 on the inner wall of the high-pressure chamber 4, and keep the opening of the flange cover 3 aligned with the guide rod installation hole 401.

[0056] Step 2: Put the return spring 2 on the guide rod 1, then install the guide rod 1 through the opening of the flange cover 3 to the guide rod installation hole 401, and install multiple return springs 2 and guide rods 1 in place in the same way.

[0057] Step 3: Put the guide cylinder 6 on the piston rod of the hydraulic cylinder 7, and make the guide tenon 703 located in the guide groove 601, and use multiple hydraulic cylinder fixing rods 5 to string the guide cylinder 6 and the hydraulic cylinder 7 together; install the nut on the hydraulic cylinder fixing rod 5, and rotate it close to the end flange of the guide cylinder 6. Do not tighten it at this time.

[0058] Step 4: Tighten each hydraulic cylinder fixing rod 5 into the fixing hole 404 in turn to ensure that the hydraulic cylinder fixing rod 5 is securely installed; then tighten the nut on the hydraulic cylinder fixing rod 5 to securely fix the guide tube 6 and the hydraulic cylinder 7.

[0059] In the actual working process, the operation is completed through the following steps:

[0060] Step 1: When feeding begins, the piston rod of the hydraulic cylinder 7 is retracted, so that the feeding trough 701 is located outside the feeding hole 403, and the bait to be fed is placed in the feeding trough 701.

[0061] Step 2: Extend the piston rod of the hydraulic cylinder 7, and the guide tenon 703 first moves in the straight section of the guide groove 601. The piston rod maintains linear translation, and the discharge trough 701, the No. 2 sealing groove 704, and the No. 2 sealing ring 702 successively enter the feeding hole 403. The piston rod continues to extend to push open the flange cover 3, and the pressure in the high-pressure chamber 4 enters the feeding hole 403. Due to the presence of the No. 2 sealing groove 704 and the No. 2 sealing ring 702, no leakage will occur.

[0062] Step 3: When the guide tenon 703 enters the arc segment of the guide groove 601, the piston rod begins to extend and rotate, causing the discharge trough 701 to flip downward, and the bait falls into the high-pressure chamber 4, completing the feeding.

[0063] Step 4: The piston rod of the hydraulic cylinder 7 contracts, and the flange cover 3 moves forward closely following the end of the piston rod under the push of the return spring 2 until it is in close contact with the No. 1 sealing groove and No. 1 sealing ring 402 on the inner wall of the boss of the high-pressure chamber 4, isolating the interior of the high-pressure chamber 4 from the feeding hole 403, ensuring that the internal pressure of the high-pressure chamber 4 does not leak out.

[0064] Step 5: Continue to retract the piston rod until the discharge trough 701, the second sealing groove 704 and the second sealing ring 702 are all out of the feeding hole 403, and the entire feeding operation is completed.
