Description

Technical Field

[0001] This application relates to the field of rock drilling technology, and in particular to a rock drilling device for a ground source heat pump. Background Technology

[0002] Drilling holes for ground source heat pumps is a key step in the construction of ground source heat pump systems. Its main process includes surveying the terrain and determining the well location, digging trenches and setting up drilling rigs, drilling holes and wells, burying heat exchange pipes, and backfilling and restoring the wellhead.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: First, some existing drilling devices cause the drill rod to vibrate and deviate when drilling into rock layers of different hardness. This not only causes the hole to be skewed, but also causes the drill to be twisted, reducing the drilling efficiency.

[0004] Secondly, the drilling process generates a large amount of rock debris and dust. Existing dust removal methods use suction ports to absorb the dust, but when the drill rod vibrates, there will be gaps between the suction port and the drilling point, and the dust can easily spread to the surrounding environment, polluting not only the construction space but also endangering the respiratory health of the workers.

[0005] To address the aforementioned problems, the inventors have proposed a rock drilling device for ground source heat pumps, which solves these problems. Utility Model Content

[0006] In order to improve the problem that some existing devices are inconvenient to use, the purpose of this utility model is to provide a rock drilling device for ground source heat pumps.

[0007] To solve the above problems, this utility model provides the following solution: a rock drilling device for a ground source heat pump, including a support frame, a drilling device body is provided on the top surface of the support frame, a limiting mechanism and a collecting mechanism are provided inside the support frame, the limiting mechanism is located above the collecting mechanism, the limiting mechanism includes a support plate, the support plate is fixedly installed inside the support frame, a through groove is opened inside the support plate, limiting plates are rotatably installed on both sides of the inner wall of the through groove, a circular groove is opened on the opposite side of the two limiting plates, two limiting rods are movably inserted into one side of the support plate, the two limiting rods respectively movably pass through the two limiting plates and are rotatably installed with a locking rod.

[0008] Preferably, the collection mechanism includes a fixing plate, which is detachably installed inside the support frame. Two sliding rods are slidably inserted into the bottom surface of the fixing plate, and a collection shell is fixedly installed at the bottom ends of the two sliding rods. Two springs are fixedly installed between the support frame and the collection shell. A through groove is opened on the top surface of both the collection shell and the fixing plate. A collection pipe is connected to one side of the collection shell, and a collection box is connected to the end of the collection pipe away from the collection shell. The collection box is fixedly installed on one side of the top surface of the support frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a limiting mechanism, can limit the drill rod through two limiting plates, reducing the possibility of it deviating. At the same time, by opening and closing multiple limiting plates, the descent of the drill bit can be unaffected, thus improving practicality.

[0010] 2. This utility model has a collection mechanism that can collect the dust sprayed from the holes. At the same time, the spring can keep the collection shell covering the holes to prevent gaps from appearing due to vibration and causing the dust to escape. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3 As shown, this utility model provides a rock drilling device for a ground source heat pump, including a support frame 1. The support frame 1 is used as a support member to support the body 11 of the drilling device.

[0018] The top surface of the support frame 1 is provided with a drilling device body 11, which is used as prior art.

[0019] The support frame 1 is equipped with a limiting mechanism 2 and a collecting mechanism 3. The limiting mechanism 2 is located above the collecting mechanism 3. The limiting mechanism 2 can limit the drill rod, and the collecting mechanism 3 can collect the dust during drilling.

[0020] The limiting mechanism 2 includes a support plate 21, which is used as a support member. The support plate 21 is fixedly installed inside the support frame 1 to prevent the device from falling off.

[0021] The support plate 21 has a through groove 22 inside, which can support the limiting plate 24 and facilitate the lowering or disassembly of the drill rod.

[0022] Limiting plates 24 are rotatably installed on both sides of the inner wall of the through groove 22. The limiting plates 24 can be opened and closed by rotating the hinges.

[0023] Two limiting plates 24 have a circular groove 25 on their opposite sides. The circular groove 25 is used in conjunction with the drilling device body 11 so that after the drill rod passes through the through groove 22, the limiting plate 24 is closed, so that the drill rod does not work in the circular groove 25.

[0024] Two limiting rods 27 are movably inserted on one side of the support plate 21. The limiting rods 27 can fix the limiting plate 24 to prevent it from falling off.

[0025] Two limiting rods 27 are respectively movably inserted through two limiting plates 24 and are rotatably mounted with locking rods 26. The locking rods 26 are set perpendicular to the limiting rods 27, so that when the locking rods 26 are perpendicular due to gravity, they will lock the limiting rods 27 in place, thereby preventing them from falling off.

[0026] Two slots 23 are provided on both sides of the support plate 21 to cooperate with the limiting rod 27, so that the limiting rod 27 can be inserted into the slot 23 to fix the limiting plate 24.

[0027] The collecting mechanism 3 includes a fixing plate 31, which is used in the prior art and can prevent the mechanism from falling off.

[0028] The fixing plate 31 is detachably installed inside the support frame 1. The fixing plate 31 is fixed by bolts, and the device can be installed when needed.

[0029] Two sliding rods 34 are slidably inserted into the bottom surface of the fixing plate 31. The sliding rods 34 are used as prior art. The top surface of the fixing plate 31 has two sliding grooves 33 that cooperate with the sliding rods 34, and can slide inside the sliding grooves 33.

[0030] An anti-detachment plate is fixedly installed at the top of the slide bar 34 to prevent the slide bar 34 from falling off.

[0031] The bottom ends of the two sliding rods 34 are fixedly installed with a collection shell 36. Two springs 35 are fixedly installed between the support frame 1 and the collection shell 36. The springs 35 can reduce the gap between the collection shell 36 and the hole.

[0032] Both the top surfaces of the collecting shell 36 and the fixing plate 31 are provided with through grooves 32. A rubber ring is provided inside the groove 32. When the drill rod is inserted into the groove 32, it can be sealed by the rubber ring.

[0033] A collection pipe 37 is connected to one side of the collection shell 36, and a collection box 38 is connected to the end of the collection pipe 37 away from the collection shell 36. The collection box 38 is fixedly installed on one side of the top surface of the support frame 1. A fan is installed inside the collection box 38 to suck up dust.

[0034] Working principle: First, the support frame 1 can be used to fix the device.

[0035] When the limiting mechanism 2 is needed, the drill rod can be moved into the through groove 22 in the middle of the support plate 21, and then the two limiting plates 24 can be rotated to squeeze the drill rod so that the drill rod is located inside the circular groove 25, thereby limiting the drill rod.

[0036] Then, the two limiting rods 27 are inserted into the slot 23 and pass through the limiting plate 24. Then, by gravity, the locking rod 26 can be rotated to fix it.

[0037] Insert the drill rod into the groove 32 on the top surface of the fixing plate 31 and the collection shell 36 and drill a hole. This will cause the fan inside the collection box 38 to work and collect the dust inside the collection shell 36 through the collection pipe 37. At the same time, due to the vibration during the drilling process, the collection shell 36 will vibrate. However, the spring 35 above will move it, allowing the collection shell 36 to move through the slide rod 34 and the slide groove 33, which can reset the collection shell 36.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
