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.

[0022] like Figure 1-Figure 7As shown, a deep geothermal sensor installation waterproof device includes a buried pipe assembly 100 and a geothermal sensor assembly 400. The buried pipe assembly 100 is buried in the ground. A sleeve 200 is inserted at the top of the buried pipe assembly 100. A sealing cover 300 is sleeved at the top of the sleeve 200. The geothermal sensor assembly 400 is accommodated in the assembly of the buried pipe assembly 100, the sleeve 200 and the sealing cover 300. A joint seal 500 is arranged between the sleeve 200 and the buried pipe assembly 100. The joint seal 500 is used to prevent ground water from entering the joint between the buried pipe assembly 100 and the sleeve 200. A rubber ring assembly 600 is arranged between the sealing cover 300 and the sleeve 200. The rubber ring assembly 600 is used to prevent rainwater from entering the joint between the sleeve 200 and the sealing cover 300. A mounting assembly 700 is arranged on the surface of the buried pipe assembly 100. The mounting assembly 700 is used to fix the buried pipe assembly 100 on the ground.

[0023] When in use, the underground pipe assembly 100 includes an underground pipe body 101 buried in the ground, and a pre-buried hole can be set in the ground in advance, and the underground pipe body 101 is inserted into the pre-buried hole. A receiving pipe 102 is fixedly installed at the center of the bottom wall of the underground pipe body 101, and the axes of the underground pipe body 101 and the receiving pipe 102 coincide. A support ring 103 is fixedly installed on the inner wall of the upper half of the underground pipe body 101, and the sleeve 200 is inserted into the top of the underground pipe body 101 and sleeved on the outside of the receiving pipe 102. The outer diameter of the sleeve 200 is equal to the inner diameter of the underground pipe body 101, and the sleeve 200 abuts against the top of the support ring 103, and the sleeve 200 is limited by the support ring 103. A water retaining plate 104 is fixedly installed on the outer wall of the upper half of the underground pipe body 101, and the height of the water retaining plate 104 gradually decreases from the inside to the outside, and the edge of the water retaining plate 104 is integrally formed with an annular flange 105. The annular flange 105 is attached to the ground to block the gap between the buried pipe body 101 and the pre-buried hole, preventing rainwater from entering the gap between the pre-buried hole and the buried pipe body 101. The top of the buried pipe body 101 is located above the ground to prevent soil from falling and adhering to the inner wall of the top of the buried pipe body 101 during daily plugging and unplugging of the sleeve 200, thereby affecting the connection between the sleeve 200 and the buried pipe body 101. The ground temperature sensor assembly 400 includes a ground temperature sensor body 401, a data line 402 is fixedly installed on the top side of the ground temperature sensor body 401, a protective tube 403 is sleeved on the outside of the ground temperature sensor body 401, a through groove 404 is opened on the surface of the protective tube 403, a finger ring buckle 405 is hinged on the top of the ground temperature sensor body 401, and the protective tube 403 is plugged into the accommodating tube 102. The finger ring buckle 405 is provided to facilitate the insertion of fingers therein, thereby facilitating the removal of the ground temperature sensor assembly 400 from the housing tube 102 .

[0024] Specifically, the joint seal 500 includes two groups of clamping rings 501 fixedly mounted on the outer wall of the lower half of the casing 200, the two groups of clamping rings 501 are distributed up and down, a rotating cover 502 is rotatably connected between the two groups of clamping rings 501, and the rotating cover 502 is limited by the two groups of clamping rings 501. The inner wall of the rotating cover 502 and the outer wall of the top of the buried pipe body 101 are correspondingly provided with threads, the rotating cover 502 is threadedly connected to the buried pipe body 101, and the bottom end of the rotating cover 502 is attached to the surface of the water retaining plate 104. Therefore, when the sleeve 200 is inserted into the buried pipe body 101, the rotating cover 502 is rotated to connect the rotating cover 502 to the outer wall of the buried pipe body 101, thereby covering the joint between the buried pipe body 101 and the sleeve 200, preventing rainwater or accumulated water from entering the joint between the buried pipe body 101 and the sleeve 200, and ensuring the firmness of the connection between the buried pipe body 101 and the sleeve 200.

[0025] After the sleeve 200 is plugged into the top of the buried pipe body 101, the assembly of the ground temperature sensor body 401 and the protection tube 403 is inserted into the interior of the accommodating tube 102. The top of the sleeve 200 is provided with a threading groove 1 201, and the data line 402 is passed through the threading groove 1 201. The sealing cover 300 is then sleeved on the top of the sleeve 200, so that the data line 402 passes through the threading groove 1 201 and is clamped between the outer wall of the sleeve 200 and the inner wall of the sealing cover 300. The bottom of the sealing cover 300 is provided with a threading groove 2 301, and the data line 402 then passes through the threading groove 2 301. The sealing cover 300 is provided with a limiting groove array on the inner wall thereof. The second threading groove 301 is connected to one of the limiting grooves 302 . The data line 402 between the sleeve 200 and the sealing cover 300 is clamped and fixed by the limiting groove 302 . The second threading groove 301 and the corresponding limiting groove 302 are used to accommodate the data line 402 .

[0026] In reality, the rubber ring assembly 600 includes a rubber ring body 601 fixedly mounted on the outer wall of the upper half of the sleeve 200. The rubber ring body 601 is used to seal the annular gap between the inner wall of the sealing cover 300 and the outer wall of the sleeve 200 to prevent rainwater from entering. A plurality of rubber strips 602 are fixedly mounted on the top of the rubber ring body 601. Inclined sheets 603 are arranged in an array on both sides of the rubber strips 602. The assembly of the rubber strips 602 and the inclined sheets 603 is inserted into the limiting groove 302. The friction between the inclined sheets 603 and the side walls of the limiting groove 302 prevents the sealing cover 300 from being separated from the sleeve 200. A sealing block 604 is fixedly mounted on the top of the rubber strip 602. The sealing block 604 is inserted into the second threading groove 301. The sealing block 604 is attached to the lower surface of the data line 402, so that the second threading groove 301 is sealed by the cooperation of the sealing block 604 and the data line 402 to prevent rainwater from entering. The sealing blocks 604 and rubber strips 602 are evenly distributed on the top of the rubber ring body 601, and the sum of the number of rubber strips 602 and sealing blocks 604 is equal to the number of limiting grooves 302. The sealing block 604 is inserted into one of the limiting grooves 302, and the rubber strips 602 correspond to the remaining limiting grooves 302 one by one.

[0027] The installation assembly 700 includes a plurality of plug rods 701 that penetrate and slide through the annular flange 105. The upper surface of the plug rod 701 is provided with a thread. The upper surface of the plug rod 701 is threadedly connected with a nut 702, and the nut 702 fits on the top of the annular flange 105. The plug rod 701 is inserted into the ground, and the nut 702 is screwed so that the nut 702 is tightly attached to the top of the annular flange 105, thereby stabilizing the buried pipe assembly 100. Prevent the buried pipe body 101 from shaking and causing a large gap with the pre-buried hole diameter on the ground. When a large gap appears between the buried pipe body 101 and the pre-buried hole, water is easily accumulated, which in turn affects the temperature of the accumulated water when it is conducted to the ground temperature sensor assembly 400, which affects the accuracy of ground temperature monitoring.
