[0031] Example 1:

[0032] Please see Figure 1-4 A seedling protection device for drainage in a seedling nursery, comprising:

[0033] The guide tube 1 has a blocking tube 2 fixedly connected to its bottom. The blocking tube 2 has a blocking component 3 inside, which is used to block the seedlings in the seedling pond.

[0034] Multiple extension seats 4 are evenly and fixedly connected to the outside of the blocking cylinder 2. Each extension seat 4 has a support rod 5 slidably connected to the middle part. Each support rod 5 has a linkage plate 6 fixedly connected to the top of the top of the multiple linkage plates 6. A linkage ring 7 is fixedly connected between the multiple linkage plates 6.

[0035] The locking plate 8 is fixedly connected to the outside of the guide tube 1. The locking component 9 is installed on the outside of the linkage ring 7. The locking component 9 is used to cooperate with the locking plate 8 to form the positioning of the support rod 5 after adjustment.

[0036] In this embodiment, a flange is fixedly connected to the top of the outer side of the guide tube 1. The flange enables the guide tube 1 to be effectively assembled with the pipe of the external drainage device.

[0037] In this embodiment, a counterweight is fixedly connected to the bottom end of each support rod 5, and the bottom end of the counterweight is provided with anti-slip texture.

[0038] Furthermore, by setting up counterweights, the contact area between the support rod 5 and the bottom of the seedling pond can be increased to a greater extent, and the overall weight can be increased to prevent the guide tube 1 and the blocking tube 2 from tipping over in the seedling pond.

[0039] In this embodiment, a scale is provided on the outer side of one of the support rods 5 to provide feedback on the distance between the extension seat 4 and the counterweight.

[0040] In this embodiment, the blocking component 3 includes:

[0041] Positioning frame 10 is fixedly connected inside the blocking cylinder 2. The middle part of the positioning frame 10 is fixedly connected to the assembly cylinder 11, and the outer side of the assembly cylinder 11 is fitted with a baffle 12.

[0042] Positioning plate 13 and baffle 12 are located between positioning frame 10 and positioning plate 13. A quick-release screw 14 is fixedly connected to the middle of positioning plate 13, and the quick-release screw 14 is also threadedly connected to the inside of assembly cylinder 11.

[0043] In this embodiment, a stabilizing strip is fixedly connected to the outer side of the positioning piece 13, and there are no fewer than three stabilizing strips;

[0044] More specifically, by setting the stabilizing strip, after the positioning piece 13 is positioned, the stabilizing strip can provide greater support for the barrier net 12, greatly ensuring the stability of the barrier net 12 application;

[0045] In this embodiment, a threaded groove is provided in the middle of the assembly cylinder 11, and the quick-release screw 14 is connected inside the threaded groove;

[0046] More specifically, by setting the threaded groove, before assembling the positioning piece 13, the quick-release screw 14 is aligned with the bottom end of the threaded groove, and the positioning piece 13 is rotated to cause the quick-release screw 14 to be screwed into the threaded groove until the positioning piece 13 contacts the baffle 12, and finally the baffle 12 is positioned between the assembly cylinder 11 and the positioning frame 10.

[0047] Furthermore, a sealing gasket is provided in the middle of the top of the positioning piece 13. With the setting of the sealing gasket, after the positioning piece 13 comes into contact with the baffle 12, the baffle 12 can pre-compress the sealing gasket, so that the sealing gasket seals the connection between the quick-release screw 14 and the threaded groove.

[0048] Example 2:

[0049] Please see Figure 2-4 This embodiment provides a technical solution based on Embodiment 1: the locking component 9 includes:

[0050] The transmission box 15 is fixedly connected to the outside of the linkage ring 7. The center shaft 16 is vertically rotatably connected to the middle of the transmission box 15. The top and bottom of the center shaft 16 are fixedly connected to the extension plate 17. The end of the extension plate 17 away from the center shaft 16 is fixedly connected to the locking plate 18, and the locking plate 18 is snapped into the locking plate 8.

[0051] The transmission shaft 19 is rotatably connected to one end of the transmission box 15. The end of the transmission shaft 19 located inside the transmission box 15 is fixedly connected to the transmission worm 20. The center shaft 16 is fixedly connected to the middle of the transmission worm wheel 21, and the transmission worm wheel 21 is meshed with the transmission worm 20.

[0052] In this embodiment, lip seals are provided at the connection between the central shaft 16 and the transmission box 15, and at the connection between the transmission box 15 and the transmission shaft 19. The lip of the lip seal faces the direction of the water in the seedling pond, so as to seal the connection between the central shaft 16 and the transmission box 15 and the transmission box 15 and the transmission shaft 19 through the lip seal, and prevent water from entering the transmission box 15.

[0053] In this embodiment, the locking plate 18 is arc-shaped, and the locking plate 8 has multiple arc-shaped locking holes, and the locking plate 18 is snapped into the corresponding arc-shaped locking holes.

[0054] More specifically, through the structural design of the locking plate 18, during the rotation of the central shaft 16, the locking plate 18 can be driven to move closer to the locking plate 8 until the locking plate 18 is engaged in the arc-shaped locking hole at the corresponding height, thereby forming a rapid positioning of the linkage ring 7.

[0055] In this embodiment, a force-bearing knob is fixedly connected to one end of the transmission shaft 19 located outside the transmission box 15. The force-bearing knob allows personnel to easily rotate the transmission shaft 19 by holding it, thereby ensuring the transmission efficiency of the transmission shaft 19.

[0056] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0057] Working principle: First, connect the top of the guide tube 1 to the water suction pipe of the drainage device. Then, rotate the drive shaft 19 to cause the drive worm 20 to move the matching worm wheel 21, which in turn drives the central shaft 16 to rotate. With the connection between the central shaft 16 and the extension plate 17, the extension plate 17 can drive the locking plate 18 to rotate. When the locking plate 18 moves out from the matching locking plate 8, the linkage ring 7 can be unlocked. Then, pull the linkage ring 7 down or up to drive the support rod 5 to slide vertically under the support of the extension seat 4 with the help of the linkage plate 6. Then measure the distance between the bottom of the support rod 5 and the bottom of the blocking tube 2. When the distance between the bottom of the support rod 5 and the bottom of the blocking tube 2 is adapted to the actual drainage depth, rotate the drive shaft 19 in the opposite direction to cause the locking plate 18 to rotate towards the matching locking plate 8 until the locking plate 18 is inserted into the arc-shaped locking hole at the corresponding height of the matching locking plate 8, thereby locking the position of the support rod 5.

[0058] Place the guide tube 1 into the seedling pond and make the support rod 5 reach the bottom of the seedling pond so that the support rod 5 can support the blocking tube 2 and the guide tube 1. Then, start the drainage device to draw the water in the seedling pond out through the blocking tube 2 and the guide tube 1 and discharge it to the designated position through the drainage device. When the water level in the seedling pond drops to the bottom of the blocking tube 2, the drainage device cannot pump out the water due to the support of the support rod 5, thus leaving a certain depth of liquid at the bottom of the pond, which can keep the bottom temperature of the pond stable and provide a relatively stable living environment for the seedlings.

[0059] The presence of the baffle net 12 inside the baffle cylinder 2 can prevent aquatic seedlings from entering the baffle cylinder 2 with the water flow during drainage, thus protecting the seedlings. The positioning plate 13 can be rotated to cause the quick-release screw 14 to disengage from the assembly cylinder 11, thereby unlocking the baffle net 12. Then, the baffle net 12 can be removed from the assembly cylinder 11 and replaced to adapt to seedlings at different stages.
