[0023] See also Figure 1-Figure 5 , an embodiment provided by the utility model: a waterproof device for a ground source heat pump greenhouse air conditioning system, comprising a bottom cover 1;

[0025] Specifically, Figure 1 , Figure 2 As shown, when in use, the butt joint between the positioning groove 14 and the positioning block 15 is utilized to ensure the correspondence between the upper and lower positions of the top cover 2 and the bottom cover 1, thereby ensuring the correspondence between the upper and lower positions of the connecting channel 803 and the movable groove 801, ensuring the normal operation of the top air mechanism 8, and under the action of the groove, the contact area between the bottom cover 1 and the top cover 2 is increased, and the tightness of the connection between the two is improved;

[0026] A top cover 2 is installed at the top of the bottom cover 1, and bolts 13 are evenly penetrated and connected between the top cover 2 and the bottom cover 1. Positioning grooves 14 are opened on both sides of the top of the bottom cover 1, and positioning blocks 15 are inserted inside the positioning grooves 14.

The inside of the air bag 6 is filled with inert gas. At the same time, the inner side of the air bag 6 is in contact with the outer wall of the vertical pipe 3. The bottom end of the fixing frame 4 and the top end of the bottom cover 1 are correspondingly connected with a top gas mechanism 8;

[0027] The air ejection mechanism 8 includes a movable groove 801 provided at the top of the bottom cover 1, and a ejection block 802 is slidably installed inside the movable groove 801, a spring 804 is installed at the bottom end of the inside of the ejection block 802, and the bottom end of the spring 804 extends to the outside of the ejection block 802 and is connected to the bottom end of the movable groove 801, a connecting channel 803 is correspondingly provided at the bottom end of the fixed frame 4 above the movable groove 801, and the top end of the ejection block 802 passes through the connecting channel 803 and abuts against the outer side of the bottom end of the upper airbag 6;

[0028] There are four top blocks 802, and the top blocks 802 are distributed in a ring shape with equal spacing on the bottom cover 1. The spring 804 is in a compressed state to push the top blocks 802 to move upward, thereby reducing the space occupied by the airbag 6 in the fixed frame 4;

[0029] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when in use, the elastic effect of the spring 804 is utilized to cause the top block 802 to squeeze the outer side of the airbag 6, so that the space of the inert gas inside the airbag 6 is compressed, and the airbag 6 is prevented from loosening when the inert gas in the airbag 6 is reduced, thereby ensuring the squeezing and sealing effect of the airbag 6 on the outer wall;

[0030] The air-pushing mechanism 8 is distributed in an annular shape with equal spacing at the bottom end of the fixed frame 4. The air-pushing mechanism 8 is used to realize automatic squeezing of the airbag 6 to ensure that the inert gas inside the airbag 6 is squeezed toward the vertical pipe 3. The inner wall of the bottom cover 1 is provided with an annular groove 10.

[0031] A transverse extrusion mechanism 9 is connected between the annular groove 10 and the top block 802, and the transverse extrusion mechanism 9 generates an inward radial driving force on the second sealing ring 12 to promote the sealing effect between the second sealing ring 12 and the outer wall of the vertical pipe 3;

[0032] The lateral extrusion mechanism 9 includes guide grooves 901 provided on both sides of the top block 802, and the guide grooves 901 are provided with lateral channels 903, the movable groove 801 and the annular groove 10 are connected with two guide sliders 902 distributed on the left and right, and a U-shaped extrusion block 904 is passed through between the two guide sliders 902, and the two ends of the U-shaped extrusion block 904 are respectively inserted into the movable groove 801, and the inner sides of the two ends of the U-shaped extrusion block 904 are respectively connected with the outer sides of the guide groove 901, and the outer side of the U-shaped extrusion block 904 is located inside the annular groove 10;

[0033] The movable groove 801 is arranged in an inclined shape, and the lower end of the movable groove 801 is closer to the vertical pipe 3 than the upper end;

[0034] A second sealing ring 12 is bonded to the inner wall of the bottom cover 1 outside the annular groove 10, and the inner wall of the second sealing ring 12 is in close contact with the outer wall of the vertical pipe 3. A first sealing ring 11 is bonded to the inner wall of the bottom cover 1 below the second sealing ring 12, and the inner wall of the first sealing ring 11 is in close contact with the outer wall of the vertical pipe 3.

[0035] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, when in use, the top block 802 is moved upward, so that the U-shaped extrusion block 904 produces radial movement under the action of 90903, so as to squeeze the second sealing ring 12, thereby promoting the close contact between the second sealing ring 12 and the outer wall of the vertical pipe 3.

[0036] Working principle: When the utility model is used, the top cover 2 and the bottom cover 1 are first connected up and down by the plugging action between the positioning groove 14 and the positioning block 15, and then the bottom cover 1 and the top cover 2 are assembled by the bolts 13, so that the vertical pipe 3 passes through the center of the bottom cover 1 and the top cover 2, the vertical pipe 3 is connected to the ground source heat pump, and the bottom cover 1, the top cover 2 and the basement floor are connected by pouring;

[0037] Secondly, the sealing sleeve 7 is screwed out of the top of the inflation tube 5, and the air is inflated into the airbag 6 through the inflation tube 5 by using an air pump, so that the inner side of the airbag 6 and the outer wall of the vertical pipe 3 are closely attached to each other, thereby cooperating with the second sealing ring 12 and the first sealing ring 11 to achieve the sealing effect of the connection gap of the vertical pipe 3 to prevent the infiltration of groundwater, and through the elastic effect of the spring 804, it drives the top block 802 to move upward, so that the top block 802 enters the interior of the fixed frame 4 to squeeze the airbag 6, so that the inert gas in the airbag 6 is squeezed and moved in the direction close to the vertical pipe 3, so as to promote the fitting effect of the airbag 6 on the vertical pipe 3 and further ensure its sealing performance;

[0038] Finally, during the upward movement of the top block 802, the guide groove 901 is synchronously driven to move upward. Since the U-shaped extrusion block 904 is limited and guided by the guide slider 902, and the transverse channel 903 is always located inside the guide groove 901, the U-shaped extrusion block 904 produces radial movement, causing the U-shaped extrusion block 904 to be extruded in the opposite direction of the vertical pipe 3, so that the U-shaped extrusion block 904 is against the second sealing ring 12, so as to promote the fit and seal between the second sealing ring 12 and the outer wall of the vertical pipe 3.
