Description

Technical Field

[0001] This utility model relates to the field of foundation engineering technology, specifically to a device for detecting sediment thickness in foundation engineering. Background Technology

[0002] The sediment thickness detection device for foundation engineering is a special equipment used to measure the thickness of sediment at the bottom of the borehole of foundation structures such as bored piles. If the sediment is too thick, it will seriously affect the bearing capacity of the pile foundation. This type of device can accurately detect the sediment thickness through various principles, providing data support for the control of project quality.

[0003] A device for detecting the thickness of sediment in foundation engineering construction is disclosed in CN221976066U. This device can be hydraulically driven to move the detection equipment, thereby enabling the pendant to move left and right. This allows the pendant to detect multiple boreholes, achieving multi-point detection, reducing the number of times the detection equipment needs to be fixed, and improving detection efficiency.

[0004] However, the sediment thickness detection device for this foundation engineering project has the following drawbacks: 1. The sediment thickness detection device for this foundation project uses a pendulum to place it into the detection area for detection. It can only detect whether sediment exists in the area, but cannot detect the thickness of the sediment, which may result in poor detection results.

[0005] 2. The sediment thickness detection device for this foundation project may have sediment adhering to it when it is inserted into the detection area. The adhering sediment may affect the subsequent detection by the detection device, resulting in differences in the detection effect of the device. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a sediment thickness detection device for foundation engineering, thereby solving the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a sediment thickness detection device for foundation engineering, comprising a detection component and a cleaning component. The detection component consists of a fixed cylinder, an adjusting shaft, a gear, a meshing block, a limiting ball, a spring, a threaded rod, an adjusting cylinder, and a detection head. The top of the fixed cylinder is rotatably connected to the adjusting shaft, and the bottom of the adjusting shaft is fixedly connected to the gear. A meshing block is engaged with the outer surface of the gear, and a limiting ball is provided on the side of the meshing block. A spring is fixedly connected to the back edge of the limiting ball. A threaded rod is fixedly connected to the bottom of the gear, and the lower surface of the threaded rod is threadedly connected to the adjusting cylinder. The bottom of the adjusting cylinder is fixedly connected to the detection head. The cleaning assembly consists of a base fixed to the lower surface of a fixed cylinder, a connecting ring, a silicone ring, and a cleaning brush. The bottom of the inner wall of the base is threaded with the connecting ring, the top of the inner wall of the connecting ring is fixedly connected with the silicone ring, and the bottom of the inner wall of the connecting ring is fixedly connected with the cleaning brush.

[0008] Preferably, the top of the inner wall of the fixed cylinder is provided with a rotating groove, and the inner wall of the rotating groove is rotatably connected to the other end of the biting block. The other end of the biting block rotates in the rotating groove on the inner wall of the fixed cylinder and then resets.

[0009] Preferably, the other end of the spring is fixedly connected to a positioning plate, one end of which is fixedly connected to the other side of the inner wall of the fixed cylinder, and the spring is mounted on the inner wall of the fixed cylinder through the positioning plate.

[0010] Preferably, a damper is fixedly connected to the center of the other end of the positioning plate, and one end of the damper is fixedly connected to the center of the back of the limiting ball. The damper is installed between the positioning plate and the limiting ball to prevent the spring from being deformed and damaged by tilting and compressing forces.

[0011] Preferably, an auxiliary plate is fixedly connected to the outer surface of the adjusting cylinder, and the outer surface of the auxiliary plate is slidably connected to the bottom of the inner wall of the fixed cylinder. The auxiliary plate on the adjusting cylinder slides in the corresponding auxiliary groove on the inner wall of the fixed cylinder to ensure that the adjusting cylinder slides horizontally downward.

[0012] Preferably, a reinforcing ring is fixedly connected to the top edge of the base, and the inner wall of the reinforcing ring is fixedly connected to one end of the lower surface of the fixed cylinder near the base. The reinforcing ring on the base can improve the connection between the base and the fixed cylinder.

[0013] (III) Beneficial Effects This utility model provides a device for detecting the thickness of sediment in foundation engineering, which has the following beneficial effects: 1. The sediment thickness detection device for this foundation engineering project, through the setup of a fixed cylinder, adjusting shaft, gear, meshing block, limiting ball, spring, threaded rod, and detection head, allows the operator to place the device in the area to be detected. The operator then rotates the adjusting shaft at the top of the fixed cylinder, causing the gear to rotate. As the gear rotates, it continuously engages with the meshing block on the side. The meshing block compresses the limiting ball on one side, which in turn compresses the spring, causing deformation. The engagement between the meshing block and the gear controls the gear's rotation frequency and improves its stability. The gear then drives the threaded rod to rotate, which in turn pushes the adjusting cylinder at the bottom out of the fixed cylinder. This allows the adjusting cylinder to insert the detection head into the sediment within the detection area to assess the sediment condition. This setup improves the detection effectiveness and ensures the stability of the device's detection process.

[0014] 2. The sediment thickness detection device for this foundation engineering project, through the setting of a fixed cylinder, base, connecting ring, silicone ring, and cleaning brush, ensures that when the detection head is pushed out of the device or needs to be retracted into the device, it will pass through the silicone ring and cleaning brush inside the connecting ring. The cleaning brush and silicone ring will clean the sediment attached to the detection head, ensuring that no sediment adheres to the detection head after it returns to the device. The staff only needs to periodically rotate the connecting ring inside the base to remove the connecting ring and clean the silicone ring and cleaning brush inside. This setting can prevent the detection head from carrying sediment and affecting the detection effect of the device. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-4 As shown, this utility model provides a technical solution: a sediment thickness detection device for foundation engineering, including a detection component 1 and a cleaning component 2. The detection component 1 consists of a fixed cylinder 101, an adjusting shaft 102, a gear 103, a meshing block 104, a limiting ball 105, a spring 106, a threaded rod 107, an adjusting cylinder 108, and a detection head 109. The top of the fixed cylinder 101 is rotatably connected to the adjusting shaft 102, and the bottom of the adjusting shaft 102 is fixedly connected to the gear 103. The outer surface of the gear 103 is engaged with the meshing block 104, and the side of the meshing block 104 is provided with a limiting ball 105. A spring 106 is fixedly connected to the back edge, and a threaded rod 107 is fixedly connected to the bottom of the gear 103. An adjusting cylinder 108 is threadedly connected to the lower surface of the threaded rod 107, and a detection head 109 is fixedly connected to the bottom of the adjusting cylinder 108. Through the arrangement of the fixed cylinder 101, adjusting shaft 102, gear 103, meshing block 104, limit ball 105, spring 106, threaded rod 107, adjusting cylinder 108, and detection head 109, during use, the operator places the device in the area to be detected and rotates the adjusting shaft 102 at the top of the fixed cylinder 101, causing it to drive the gear 103 to rotate. During rotation, gear 103 continuously engages with the side meshing block 104. The meshing block 104 compresses the side limiting ball 105, which in turn compresses the spring 106, causing it to deform. The engagement between the meshing block 104 and gear 103 controls the rotation frequency of gear 103 and improves its rotational stability. Gear 103 drives the threaded rod 107 to rotate, which in turn drives the bottom adjusting cylinder 108 to push out of the fixed cylinder 101. This allows the adjusting cylinder 108 to drive the bottom detection head 109 to insert into the sediment within the detection area for sediment detection. This setup improves the device's detection efficiency. To ensure the effectiveness and stability of the detection device, the fixed cylinder 101 is made of 304 stainless steel, the adjusting shaft 102 is made of 45 high-quality carbon structural steel, the gear 103 is made of 20CrMnTi alloy structural steel, the meshing block 104 is made of polyoxymethylene (POM) engineering plastic, the limit ball 105 is made of GCr15 bearing steel, the spring 106 is made of 60Si2Mn spring steel, the threaded rod 107 is made of 304 stainless steel, the adjusting cylinder 108 is made of 6061 aluminum alloy, and the detection head 109 has a built-in pressure sensor (model: PT124G-111) and a displacement sensor (model: KTC-100). Cleaning component 2 consists of a base 201 fixed to the lower surface of the fixed cylinder 101, a connecting ring 202, a silicone ring 203, and a cleaning brush 204. The connecting ring 202 is threaded to the bottom of the inner wall of the base 201. The silicone ring 203 is fixedly connected to the top of the inner wall of the connecting ring 202, and the cleaning brush 204 is fixedly connected to the bottom of the inner wall of the connecting ring 202. Through the arrangement of the fixed cylinder 101, base 201, connecting ring 202, silicone ring 203, and cleaning brush 204, when the detection head 109 is pushed out of the device or needs to be retracted into the device, the silicone ring 203 will pass through the silicone ring 202. The silicone ring 203 and cleaning brush 204 clean the sediment attached to the detection head 109, ensuring that the detection head 109 is free of sediment after returning to the device. The operator only needs to periodically rotate the connecting ring 202 inside the base 201 to remove the connecting ring 202 and clean the silicone ring 203 and cleaning brush 204 inside. This design can prevent the detection head 109 from carrying sediment and affecting the detection effect of the device. The base 201 is made of 304 stainless steel, the connecting ring 202 is made of ABS engineering plastic, the silicone ring 203 is made of food-grade silicone rubber, and the cleaning brush 204 is made of nylon filament. A rotating groove is provided on the top of the inner side wall of the fixed cylinder 101. The inner wall of the rotating groove is rotatably connected to the other end of the meshing block 104. Through the setting of the fixed cylinder 101 and the meshing block 104, when in use, the other end of the meshing block 104 rotates in the rotating groove on the inner wall of the fixed cylinder 101 and then resets. The other end of the spring 106 is fixedly connected to the positioning plate 3. One end of the positioning plate 3 is fixedly connected to the other side of the inner wall of the fixed cylinder 101. Through the arrangement of the spring 106, the positioning plate 3 and the fixed cylinder 101, the spring 106 is installed on the inner wall of the fixed cylinder 101 through the positioning plate 3 during use. A damper 4 is fixedly connected to the center of the other end of the positioning plate 3. One end of the damper 4 is fixedly connected to the center of the back of the limiting ball 105. With the arrangement of the positioning plate 3, the damper 4 and the limiting ball 105, the damper 4 is installed between the positioning plate 3 and the limiting ball 105 during use to prevent the spring 106 from being deformed and damaged by tilting and squeezing force. An auxiliary plate 5 is fixedly connected to the outer surface of the adjusting cylinder 108. The outer surface of the auxiliary plate 5 is slidably connected to the bottom of the inner wall of the fixed cylinder 101. With the setting of the adjusting cylinder 108, the auxiliary plate 5 and the fixed cylinder 101, when in use, the auxiliary plate 5 on the adjusting cylinder 108 slides in the corresponding auxiliary groove on the inner wall of the fixed cylinder 101 to ensure that the adjusting cylinder 108 slides horizontally downward. A reinforcing ring 6 is fixedly connected to the top edge of the base 201. The inner wall of the reinforcing ring 6 is fixedly connected to the lower surface of the fixing cylinder 101 near the end of the base 201. Through the arrangement of the base 201, the reinforcing ring 6 and the fixing cylinder 101, the reinforcing ring 6 on the base 201 can improve the connection between the base 201 and the fixing cylinder 101 during use.

[0019] First step: The staff places the device in the area to be tested, rotates the adjusting shaft 102 at the top of the fixed cylinder 101, and drives the gear 103 to rotate. When the gear 103 rotates, it will continuously engage with the meshing block 104 on the side. The meshing block 104 will compress the limiting ball 105 on one side. The limiting ball 105 will compress the spring 106 and deform. The engagement between the meshing block 104 and the gear 103 will control the rotation frequency of the gear 103 and improve the stability of the gear 103's rotation. The gear 103 will drive the threaded rod 107 to rotate. The threaded rod 107 will drive the adjusting cylinder 108 at the bottom to push out of the fixed cylinder 101, so that the adjusting cylinder 108 drives the detection head 109 at the bottom to be inserted into the sediment in the testing area to detect the condition of the sediment. The second step: When the detection head 109 is pushed out of the device or needs to be put back into the device, it will pass through the silicone ring 203 and cleaning brush 204 inside the connecting ring 202. The cleaning brush 204 and the silicone ring 203 will clean the sediment attached to the detection head 109, ensuring that no sediment is attached after the detection head 109 returns to the device. The staff only needs to rotate the connecting ring 202 inside the base 201 periodically to remove the connecting ring 202 and clean the silicone ring 203 and cleaning brush 204 inside it.
