Description

Technical Field

[0001] This utility model relates to the field of geothermal monitoring, and more specifically, to a waterproof device for installing a deep geothermal sensor. Background Technology

[0002] Geological exploration, geothermal monitoring, meteorological observation and other fields require the use of ground temperature sensors. Ground temperature sensors usually require first burying pipes in the ground, and then inserting the ground temperature sensor into the buried pipes to monitor the ground temperature at different depths.

[0003] A search revealed that Chinese Patent Publication No. CN222258495U discloses "a waterproof device for installing a deep geothermal sensor, comprising a buried pipe assembly and a geothermal sensor assembly. The buried pipe assembly is embedded in the ground, and a sleeve is inserted into the top of the buried pipe assembly. A sealing cover is fitted onto the top of the sleeve. The geothermal sensor assembly is housed within the buried pipe assembly, sleeve, and sealing cover assembly. A joint seal is provided between the sleeve and the buried pipe assembly to prevent surface water from entering the joint between the buried pipe assembly and the sleeve. A rubber ring assembly is provided between the sealing cover and the sleeve to prevent rainwater from entering the joint between the sleeve and the sealing cover. An installation component is provided on the surface of the buried pipe assembly to fix the buried pipe assembly to the ground. This utility model has the advantages of good waterproofing and more accurate geothermal monitoring." However, it still has the following drawbacks:

[0004] When in use, the device cannot absorb or block moisture in the soil. Since the humidity varies in different soils, when the ground temperature sensor is used in the soil for a long time, a large amount of moisture will invade the electronic components inside the ground temperature sensor, leading to water damage.

[0005] Therefore, a waterproof installation device for deep geothermal sensors is proposed. Utility Model Content

[0006] The purpose of this invention is to address the current problem that soil temperature sensors cannot effectively absorb and block moisture. Due to the varying humidity levels in different soil types, when soil temperature sensors are used for extended periods, a large amount of moisture can damage the electronic components inside the sensors, leading to water ingress and damage.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a waterproof device for installing a deep geothermal sensor, including an installation tube, wherein the installation tube is provided with an installation mechanism for protecting and fixing the sensor, and an adjustment component for guiding the sensor cable is provided on one side of the installation mechanism.

[0009] The installation mechanism includes an installation plate that is slidably connected to the inner wall of the installation tube. A ground temperature sensor is installed on the top of the installation plate, and a placement frame is threaded to the bottom of the installation plate. Multiple drainage holes are opened through the bottom of the placement frame, and multiple silicone blocks are installed inside the placement frame. A support ring is fixedly connected to the inner wall of the installation tube and fits against the bottom of the placement frame. A rotating cap is threaded to the bottom of the installation tube. The probe of the ground temperature sensor passes vertically through the placement frame, the support ring, and the rotating cap and extends to the outside of the installation tube. An extension plate is fixedly connected to the outer wall of the installation tube, and a shielding cap is bolted to the top of the extension plate.

[0010] As a preferred technical solution of this utility model, the adjustment component includes a threaded column fixedly connected to the top of the mounting plate, an internal threaded sleeve threadedly connected to the outer wall of the threaded column, a support plate rotatably connected to the top of the internal threaded sleeve, a fixing rod fixedly connected to the top of the mounting plate through the support plate and symmetrically arranged with the threaded column, the support plate sliding along the length direction of the fixing rod, and a conduit fixedly connected to the top of the support plate.

[0011] As a preferred technical solution of this utility model, a protective plate is fixedly connected to the outer wall of the installation tube, and multiple insertion rods are slidably connected inside the protective plate. Each of the multiple insertion rods has a limiting plate fixedly connected to its outer wall, and the bottom of the limiting plate is in contact with the top of the protective plate.

[0012] As a preferred technical solution of this utility model, two pull rods are fixedly connected to the top of the mounting plate, and the top of the pull rods is in contact with the bottom of the shielding cap at the mounting tube.

[0013] As a preferred technical solution of this utility model, the inner wall of the rotating cap is provided with a funnel-shaped sealing tube, and the inner wall of the funnel-shaped sealing tube is tightly fitted with the outer wall of the probe of the ground temperature sensor.

[0014] As a preferred technical solution of this utility model, a retaining ring is fixedly connected to the top of the shielding cap, and a sealing block is provided inside the retaining ring.

[0015] As a preferred technical solution of this utility model, a sealing gasket is provided at the bottom of the rotating cap at the mounting tube, and the bottom of the sealing gasket is in close contact with the top of the mounting tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The installation mechanism effectively absorbs and blocks moisture from the soil. The installation tube provides protection for the ground temperature sensor. When the sensor is used in the soil, the silicone block in the placement frame absorbs soil moisture that enters the installation tube through the perforations. Meanwhile, the extension plate and shielding cap shield the top of the installation tube, preventing external rainwater from entering. Since the placement frame is threaded to the bottom of the installation plate, it is convenient for users to replace the silicone block regularly, thus improving the waterproof effect of the ground temperature sensor.

[0018] 2. The adjustable components provide guidance and protection for the ground temperature sensor cable. By rotating the internal threaded sleeve, the support plate can slide up and down along the length of the fixed rod, and the ground temperature sensor cable can be extended to the outside of the mounting pipe through the conduit, thus improving the protection of the cable.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figure 1 and Figure 2 As shown, this embodiment proposes a waterproof installation device for a deep geothermal sensor, including an installation pipe 1. The installation pipe 1 is provided with an installation mechanism 2 for protecting and fixing the sensor. An adjustment component 3 for guiding the sensor cable is provided on one side of the installation mechanism 2.

[0030] like Figure 2 and Figure 3As shown, the installation mechanism 2 includes an installation plate 201 that is slidably connected to the inner wall of the installation pipe 1. A ground temperature sensor 202 is installed on the top of the installation plate 201, allowing the ground temperature sensor 202 to be installed. A placement frame 203 is threadedly connected to the bottom of the installation plate 201. Multiple drainage holes 204 are provided through the bottom of the placement frame 203. Multiple silicone blocks 205 are placed inside the placement frame 203, which can absorb moisture from the soil. A support ring 206 is fixedly connected to the inner wall of the installation pipe 1 and is connected to the bottom of the placement frame 203. The support ring 206 can improve the support effect on the placement frame 203. The bottom of the installation tube 1 is threaded with a rotating cap 207. The probe of the ground temperature sensor 202 passes vertically through the placement frame 203, the support ring 206 and the rotating cap 207 and extends to the outside of the installation tube 1. The rotating cap 207 can reduce the contact area between the bottom of the installation tube 1 and the soil. An extension plate 208 is fixedly connected to the outer wall of the installation tube 1. A shielding cap 209 is bolted to the top of the extension plate 208. The extension plate 208 and the shielding cap 209 can provide shielding protection for the top of the installation tube 1. In use, the installation tube 1 is placed into the pre-dug hole. The probe of the ground temperature sensor 202 can monitor the soil temperature in real time. When the soil moisture is high, it will enter the installation tube 1 through the gap between the rotating cap 207 and the probe. At this time, the moisture will be absorbed by the silicone block 205 through the leakage hole 204 at the placement frame 203, preventing the electronic components in the ground temperature sensor 202 from being damaged by moisture. After fixing the shielding cap 209 to the extension plate 208, the top of the installation tube 1 can be shielded and protected to prevent external rainwater from entering the installation tube 1. At the same time, since the placement frame 203 is threaded to the bottom of the installation plate 201, it is convenient for the user to replace the silicone block 205, which improves the waterproof effect of the ground temperature sensor 202.

[0031] like Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the adjusting component 3 further includes a threaded post 301 fixedly connected to the top of the mounting plate 201. An internally threaded sleeve 302 is threadedly connected to the outer wall of the threaded post 301. A support plate 303 is rotatably connected to the top of the internally threaded sleeve 302. A fixing rod 304, penetrating the support plate 303, is fixedly connected to the top of the mounting plate 201 and is symmetrically arranged with the threaded post 301. The support plate 303 slides along the length of the fixing rod 304, and a conduit 305 is fixedly connected to the top of the support plate 303. The cable carried on the ground temperature sensor 202 can be placed in the conduit 305 and extended to the top of the mounting tube 1, facilitating connection to an external display device. By rotating the internally threaded sleeve 302, the support plate 303 can move up and down along the length of the fixing rod 304, facilitating adaptation to ground temperature sensors 202 of different sizes on the mounting plate 201.

[0032] like Figure 4 As shown, in a preferred embodiment, based on the above method, a protective plate 4 is further fixedly connected to the outer wall of the mounting pipe 1. Multiple insertion rods 5 are slidably connected inside the protective plate 4. Limiting plates 6 are fixedly connected to the outer walls of each insertion rod 5, with the bottom of the limiting plate 6 abutting against the top of the protective plate 4. The protective plate 4 provides shielding protection for the gap between the pre-embedded hole and the outer wall of the mounting pipe 1, preventing external rainwater from entering the pre-embedded hole. The insertion rods 5 improve the stability of the mounting pipe 1 within the pre-embedded hole.

[0033] like Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, two pull rods 7 are further fixedly connected to the top of the mounting plate 201, and the top of the pull rods 7 is in contact with the bottom of the shield cap 209 at the mounting tube 1. By pulling the rods 7, the mounting plate 201 can be easily pulled out of the mounting tube 1; at the same time, after the shield cap 209 is fixed, the top of the pull rods 7 can be squeezed to improve the stability of the mounting plate 201 in the mounting tube 1.

[0034] like Figure 2 As shown, in a preferred embodiment, based on the above method, the inner wall of the rotating cap 207 is further provided with a funnel-shaped sealing tube 8, and the inner wall of the funnel-shaped sealing tube 8 is tightly fitted with the outer wall of the probe of the ground temperature sensor 202. The funnel-shaped sealing tube 8 can improve the sealing performance of the rotating cap 207 and prevent the part of the ground temperature sensor 202 extending outside the rotating cap 207 from shaking.

[0035] like Figure 4 As shown, in a preferred embodiment, based on the above method, a retaining ring 9 is fixedly connected to the top of the shielding cap 209, and a sealing block 10 is provided inside the retaining ring 9. After the sealing block 10 is placed in the retaining ring 9, it can seal and shield the gap between the conduit 305 and the rotating cap 207.

[0036] like Figure 4 As shown, in a preferred embodiment, based on the above method, a sealing gasket 11 is further provided at the bottom of the rotating cap 207 at the mounting tube 1, and the bottom of the sealing gasket 11 is in close contact with the top of the mounting tube 1. The sealing gasket 11 can improve the sealing performance between the rotating cap 207 and the mounting tube 1.

[0037] Specifically, when using this deep geothermal sensor waterproof installation device: pull out the installation tube 1 from the mounting plate 201 using the pull rod 7, fix the geothermal sensor 202 to the top of the mounting plate 201, then place the silicone block 205 in the placement frame 203, and fix the placement frame 203 to the bottom of the mounting plate 201 (e.g., Figure 2 , Figure 3 and Figure 4 (As shown); by rotating the internal threaded sleeve 302, the support plate 303 slides along the length of the fixed rod 304, allowing the cable carried on the ground temperature sensor 202 to be placed into the conduit 305 and extended to the outside of the mounting pipe 1 for connection to an external display device (e.g. Figure 2 and Figure 5 (As shown); Finally, place the mounting plate 201 into the mounting tube 1, so that the probe of the ground temperature sensor 202 extends out of the bottom of the mounting tube 1. Screw the rotating cap 207 into the bottom of the mounting tube 1, and make the inner wall of the funnel-shaped sealing tube 8 fit tightly against the outer wall of the probe of the ground temperature sensor 202. Place the prepared mounting tube 1 into the pre-dug hole. The probe of the ground temperature sensor 202 can monitor the soil temperature in real time. The soil moisture entering the mounting tube 1 will be absorbed by the silicone block 205 in the placement frame 203, while the shielding cap 209 can shield and protect the top of the mounting tube 1 to prevent external rainwater from entering the mounting tube 1 (e.g., Figure 2 (As shown).

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
