Description

Technical Field

[0001] This application relates to the technical field of engineering testing, and in particular to a drilling and limiting tool for detecting soil radon concentration. Background Technology

[0002] Radon is currently the second leading cause of lung cancer in humans. Excessive release of radon from soil can cause serious harm to the human body, and soil radon is also a major source of indoor radon.

[0003] When drilling holes for soil radon concentration testing, using electric or diesel-assisted drilling, while labor-saving, causes significant vibration to the surrounding soil, leading to gas movement within the soil. This is unacceptable in the suction method for measuring radon concentration, so this drilling method is only suitable for the cup-buried method. Therefore, in related technologies, large-diameter threaded steel or large-diameter round steel is generally used for direct drilling, thus avoiding excessive vibration to the surrounding soil and preventing gas movement within the soil.

[0004] Regarding the aforementioned technologies, the inventors believe that by directly drilling holes using large-diameter threaded steel or large-diameter round steel, it is difficult to pull out the entire threaded steel or round steel after drilling, and it is difficult to control the hole depth within the specified requirements, which easily leads to low testing efficiency and drilling depth that does not meet the standard requirements. Utility Model Content

[0005] The purpose of this application is to provide a drilling and limiting tool for soil radon concentration detection, in order to solve the problems of low detection efficiency and non-compliance with standard requirements caused by directly drilling with large-diameter threaded steel or round steel.

[0006] The soil radon concentration detection drilling and limiting tool provided in this application adopts the following technical solution:

[0007] A soil radon concentration detection drilling and limiting tool includes a steel rod body. The outer side wall of the steel rod body is provided with multiple height marking lines. The top of the steel rod body is provided with a gripping member through a fastening device. The fastening device includes a fastening threaded rod provided on the gripping member. The top of the steel rod body is provided with a threaded hole that is threadedly connected to the fastening threaded rod. A locking component is also provided between the outer side of the fastening threaded rod and the wall of the threaded hole.

[0008] Furthermore, the two ends of the steel rod body are respectively shaped like a pointed top and a rounded bottom.

[0009] Furthermore, the main body of the steel rod is integrally formed from multiple steel rods, and the diameter of the multiple steel rods gradually decreases from the direction away from the gripper.

[0010] Furthermore, an arc-shaped chamfer structure is provided between two adjacent steel rods.

[0011] Furthermore, a sliding hole is provided on the outer side of one end of the fastening threaded rod, and the locking assembly includes sliding blocks symmetrically slidably disposed in the sliding hole. A telescopic spring is connected between the two sliding blocks, and a locking head is provided at the opposite ends of the two sliding blocks. Locking grooves that cooperate with the locking heads are symmetrically provided in the wall of the threaded hole.

[0012] Furthermore, the locking head has an arc-shaped structure.

[0013] Furthermore, the steel rod body has an internal cavity that communicates with the threaded hole.

[0014] Furthermore, the grip is fitted with an anti-slip sleeve.

[0015] Compared with the prior art, the beneficial effect of this application is that by setting multiple height marking lines on the main body of the steel rod, the drilling depth can be easily controlled when drilling with the main body of the steel rod, so that the drilling depth meets the standard requirements.

[0016] Meanwhile, by using a fastening device to securely install the gripper onto the steel rod body, not only can the steel rod body be easily inserted into the soil to achieve the drilling effect, but also, after drilling to the required depth, the steel rod body can be pulled out by holding the gripper and rotating it upwards. This makes drilling and pulling out easier and faster, and the detection data more reliable and accurate. In this way, the problems of difficulty in inserting and pulling out holes and difficulty in determining the drilling depth for soil radon concentration detection, which affect the detection efficiency and accuracy, are solved.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a soil radon concentration detection drilling and positioning tool, referring to... Figure 1 In this embodiment, the steel rod body 1, height marking line 11, gripping member, and fastening device are included. The steel rod body 1 has an overall conical structure; specifically, both ends of the steel rod body 1 are tapered at the top and rounded at the bottom. This design facilitates drilling by utilizing the tapered top and rounded bottom characteristics. More specifically, the overall length of the steel rod body 1 is 1000mm, and its bottom diameter is 25mm.

[0024] Better, refer to Figure 1 and Figure 2 In this embodiment, the main body 1 of the steel rod is integrally formed from multiple steel rods. The diameter of the multiple steel rods gradually decreases from the direction away from the handle 2, and an arc-shaped chamfer structure 13 is provided between two adjacent steel rods. Through the above design, the resistance between the main body 1 of the steel rod and the soil can be reduced, so that the main body 1 of the steel rod can be inserted into the soil more easily, or the main body 1 of the steel rod can be easily pulled out of the soil.

[0025] At the same time, refer to Figure 1 In this embodiment, multiple height marking lines 11 are provided, and these height marking lines 11 are respectively fixedly installed on the outer wall of the steel rod body 1. Specifically, these height marking lines 11 are located at positions 400mm, 500mm, and 600mm away from the tip of the steel rod body 1. It should be noted here that the drilling depth is required to be between 400mm and 600mm.

[0026] By setting these height marking lines 11, the drilling depth can be easily controlled when drilling with the steel drill body 1, thus ensuring that the drilling depth meets the standard requirements. More specifically, these height marking lines 11 are color-coded, which not only allows for better control of the drilling depth but also provides a more effective visual observation effect.

[0027] Additionally, refer to Figure 3 and Figure 4In this embodiment, the grip is detachably mounted on the top of the round end of the steel rod body 1 by means of a fastening device, and the grip is a handle 2. The handle 2 is a cylindrical structure with a length of 300mm and a diameter of 30mm. At the same time, an anti-slip sleeve 21 is also provided on the handle 2, which can effectively prevent slipping when gripping the handle 2.

[0028] Specifically, the fastening device includes a fastening threaded rod 3 and a locking assembly. One end of the fastening threaded rod 3 is fixedly installed on the outer side of the middle part of the handle 2, so that the handle 2 and the fastening threaded rod 3 are combined into a T-shaped structure.

[0029] Furthermore, a threaded hole 12 is provided at the middle of the top of the round end of the steel rod body 1, and the fastening threaded rod 3 is threadedly connected to the threaded hole 12; in this way, the handle 2 is screwed into the threaded hole 12 of the steel rod body 1 through the fastening threaded rod 3, thereby fixing the handle 2 onto the steel rod body 1, and then the steel rod body 1 can be easily inserted into the soil using the handle 2 to achieve the drilling effect.

[0030] Meanwhile, by twisting the threaded rod 3 in the reverse direction within the threaded hole 12, the steel rod body 1 and the handle 2 can be easily separated, thus facilitating storage or replacement.

[0031] Preferably, in this embodiment, a cavity 14 is provided inside the steel rod body 1, which is connected to the threaded hole 12. This can reduce the overall weight of the steel rod body 1 and make it easier for the drilling personnel to use.

[0032] In addition, refer to Figure 3 and Figure 4 In this embodiment, the locking assembly is disposed between the outer side of the fastening threaded rod 3 and the wall of the threaded hole 12. Specifically, the locking assembly includes a sliding block 4, a telescopic spring 5, and a locking head 41. A sliding hole 31 is provided on the outer side of the end of the fastening threaded rod 3 away from the handle 2, and two sliding blocks 4 are provided, symmetrically slidingly installed inside the sliding hole 31. The two ends of the telescopic spring 5 are respectively fixedly connected to corresponding sides of the two sliding blocks 4. Two locking heads 41 are provided, respectively installed on opposite sides of the two sliding blocks 4.

[0033] When the telescopic spring 5 is in its normal state, the locking heads 41 on both sliding blocks 4 extend out of the fastening threaded rod 3 along the sliding hole 31; when pressure is applied to the two locking heads 41, the two sliding blocks 4 slide closer to each other to compress the telescopic spring 5, at which time the telescopic spring 5 is in a compressed state.

[0034] When the pressure on the two locking heads 41 is released, the elastic reset action of the telescopic spring 5 will push the two sliding blocks 4 simultaneously, causing the two sliding blocks 4 to slide away from each other, thereby driving the two locking heads 41 to extend out of the fastening threaded rod 3. At this time, the telescopic spring 5 returns to its normal state.

[0035] Meanwhile, locking grooves 15 are symmetrically provided in the wall of the threaded hole 12, and the locking grooves 15 cooperate with the locking head 41. When the fastening threaded rod 3 is turned into the threaded hole 12, the groove wall of the locking groove 15 applies pressure to the locking head 41, so that the locking head 41 slides into the interior of the fastening threaded rod 3 along the sliding hole 31 under the action of the sliding block 4 and the telescopic spring 5. When the locking groove 15 corresponds to the sliding hole 31, the pressure of the locking head 41 is released. Under the elastic reset action of the telescopic spring 5, the locking head 41 is locked in the locking groove 15, thereby further effectively locking the fastening threaded rod 3.

[0036] Preferably, in this embodiment, the two locking heads 41 are both arc-shaped on the side away from the telescopic spring 5. By setting the locking heads 41 with arc-shaped structures, when the threaded rod 3 is turned out of the threaded hole 12, the locking groove 15 can more effectively apply pressure to the locking heads 41, causing the locking heads 41 to retract and slide into the sliding hole 31. This makes it easier to unlock the threaded rod 3 and turn it out of the threaded hole 12.

[0037] After drilling to the required depth, the steel rod body 1 is pulled out by holding the handle 2 and rotating it upwards under the action of locking head 41 locking the locking groove 15. This makes drilling and pulling out easier and faster, and the test data more reliable and accurate. This solves the problem that drilling holes for soil radon concentration detection is difficult to insert and pull out, and the drilling depth is difficult to determine, which affects the detection efficiency and accuracy.

[0038] The implementation principle of the soil radon concentration detection drilling and limiting tool in this application embodiment is as follows: During operation, the steel rod body 1 is used to drill a hole to the standard specified depth range. Then, by holding the handle 2 and rotating it upward, the steel rod body 1 is pulled out. Subsequently, the air extraction rod of the soil radon concentration detector is immediately inserted and the hole is sealed, thereby enabling the measurement of soil radon concentration.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
