Description

Technical Field

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

[0002] The sediment thickness detection device for foundation engineering is an important technology for assessing the thickness of sediment layers in foundations. This method uses specialized measuring tools at the foundation construction site to systematically acquire sediment thickness data, providing a scientific basis for subsequent engineering decisions. This method typically involves vertically inserting a probe into the bottom of the foundation and determining the actual thickness of the sediment through physical touch or instrumental measurement. Sediment thickness is a crucial parameter for assessing the bearing capacity and stability of the foundation; excessively thick sediment layers can lead to foundation settlement, deformation, and other problems, affecting the safety of the structure. Using the sediment thickness probe and slab measurement method, engineers can effectively identify the distribution of sediment and analyze potential geological problems. This not only helps optimize foundation design schemes but also reduces risks during construction, ensuring the smooth progress of the project.

[0003] In some existing foundation engineering sediment thickness detection devices, the probe and the measuring cake are set up separately. Since the measuring cake needs to be placed on the sediment surface, it may be necessary to enter the foundation when retrieving it, resulting in a poor user experience. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sediment thickness detection device for foundation engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sediment thickness detection device for foundation engineering includes a support cylinder. A measuring cake is fixedly connected to the bottom of the support cylinder. Two symmetrically arranged receiving slots are formed inside the measuring cake. Locking plates are slidably connected inside each of the two receiving slots. The surface of each locking plate away from the support cylinder is provided with an adjustment mechanism for adjusting the locking plates. A measuring needle is slidably connected to the top of the support cylinder. Multiple locking grooves are formed on the surface of the measuring needle near the two locking plates, and the multiple locking grooves are configured to cooperate with the locking plates. A gravity block is fixedly connected to the top of the measuring needle. Two symmetrically arranged sliding grooves are formed on the surface of the measuring needle. The sliding grooves are provided with a constraint mechanism for restraining the measuring needle. A rotating shaft is rotatably connected inside the measuring needle. The surface of the rotating shaft is provided with a striking mechanism for striking the measuring needle. The locking plates prevent the user from entering the foundation when retrieving the measuring cake.

[0007] As a further embodiment of this utility model, the adjustment mechanism includes a support rod, which is fixedly connected to one side of the locking plate and slidably connected to one side of the storage groove. A first spring is sleeved on the surface of the support rod, with one end of the first spring fixedly connected to one side of the locking plate and the other end of the first spring fixedly connected to one side of the storage groove. A pull plate is fixedly connected to the other end of the support rod and slidably connected to the top of the measuring disc. An adjustment ring is rotatably connected to the surface of the support cylinder near the pull plate. Two limiting cones are symmetrically fixedly connected to the surface of the adjustment ring. A limiting groove is formed on the surface of the pull plate near the adjustment ring. The limiting groove and the limiting cones are configured to cooperate with each other. The locking plate can be adjusted by the pull plate.

[0008] As a further embodiment of this utility model, the constraint mechanism includes a limiting rod, which is fixedly connected to one side inside the slide groove. A pressure plate is sleeved on the surface of the limiting rod, and a second spring is sleeved on the surface of the limiting rod near the slide groove. One end of the second spring is fixedly connected to one side of the pressure plate, and the other end of the second spring is fixedly connected to one side inside the slide groove. By setting the pressure plate, the probe can be constrained.

[0009] As a further embodiment of this utility model, the striking mechanism includes multiple turntables, each turntable being fitted onto the surface of a rotating shaft. Three striking elements are rotatably connected to the surfaces of each turntable. The three striking elements are evenly arranged in a ring and are configured to cooperate with the probe. A worm gear is fitted onto the surface of the rotating shaft near the pressure plate, and a worm is fitted onto the surface of the worm gear. The worm is rotatably connected to one side of the probe. A gear is fitted onto the surface of the worm away from the worm gear, and a rack is fitted onto the surface of the gear. The rack is fixedly connected to one side of the support cylinder. The striking elements allow the probe to be struck.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a technical solution of restraining the probe with locking plates, thus avoiding the need for users to enter the foundation when retrieving the test cake. This effectively solves the problem of poor user experience caused by the need to enter the foundation to retrieve the test cake, which is placed on the sediment surface. Two locking plates are installed inside the test cake, and both locking plates cooperate with the locking grooves on the surface of the probe. Due to the design of the locking grooves, the probe can be moved downward normally. However, when the probe moves upward, the locking plates restrict the probe through the locking grooves, preventing it from moving upward. Since the probe cannot move upward independently, it can be moved upward along with the test cake when retrieved, avoiding the need for users to enter the foundation to remove the test cake.

A measuring cake 101 is fixedly connected to the bottom of the support cylinder 1. Two symmetrically arranged storage slots 102 are opened inside the measuring cake 101. Locking plates 304 are slidably connected inside the two storage slots 102. The surface of the two locking plates 304 away from the support cylinder 1 is provided with an adjustment mechanism for adjusting the locking plates 304. A measuring needle 2 is slidably connected to the top of the support cylinder 1. Multiple locking grooves 203 are opened on the surface of the measuring needle 2 near the two locking plates 304, and the multiple locking grooves 203 are all configured to cooperate with the locking plates 304. A gravity block 201 is fixedly connected to the top of the measuring needle 2. Two symmetrically arranged sliding grooves 204 are opened on the surface of the measuring needle 2. The two sliding grooves 204 are provided with a constraint mechanism for constraining the measuring needle 2. A rotating shaft 5 is rotatably connected inside the measuring needle 2. The surface of the rotating shaft 5 is provided with a striking mechanism for striking the measuring needle 2. The setting of the locking plates 304 can avoid the user from having to enter the foundation when taking the measuring cake 101.

[0021] Preferably, the adjustment mechanism includes a support rod 302, which is fixedly connected to one side of the locking plate 304 and slidably connected to one side of the storage groove 102. A first spring 303 is sleeved on the surface of the support rod 302. One end of the first spring 303 is fixedly connected to one side of the locking plate 304, and the other end of the first spring 303 is fixedly connected to one side of the storage groove 102. The locking plate 304 can be reset by the setting of the first spring 303. A pull plate 3 is fixedly connected to the other end of the support rod 302. The pull plate 3 is slidably connected to the top of the measuring disc 101. An adjustment ring 305 is rotatably connected to the surface of the support cylinder 1 near the pull plate 3. Two limiting cones 306 are symmetrically fixedly connected to the surface of the adjustment ring 305. A limiting groove 301 is opened on the surface of the pull plate 3 near the adjustment ring 305. The limiting groove 301 and the limiting cone 306 are configured to cooperate with each other. The locking plate 304 can be adjusted by the setting of the pull plate 3.

[0022] Furthermore, the constraint mechanism includes a limiting rod 401, which is fixedly connected to one side of the slide groove 204. A pressure plate 4 is sleeved on the surface of the limiting rod 401, and a second spring 402 is sleeved on the surface of the limiting rod 401 near the slide groove 204. The pressure plate 4 can be reset by the setting of the second spring 402. One end of the second spring 402 is fixedly connected to one side of the pressure plate 4, and the other end of the second spring 402 is fixedly connected to one side of the slide groove 204. The probe 2 can be constrained by the setting of the pressure plate 4.

[0023] Preferably, the striking mechanism includes multiple turntables 501, each of which is sleeved on the surface of the rotating shaft 5. Three striking elements 502 are rotatably connected to the surface of each turntable 501. The three striking elements 502 are evenly arranged in a ring and cooperate with the probe 2. A worm gear 503 is sleeved on the surface of the rotating shaft 5 near the pressure plate 4. The worm gear 503 allows the striking elements 502 to rotate. A worm 504 is fitted onto the surface of the worm gear 503 and rotatably connected to one side of the probe 2. A gear 505 is sleeved on the surface of the worm 504 away from the worm gear 503. A rack 506 is fitted onto the surface of the gear 505 and fixedly connected to one side of the support cylinder 1. The striking elements 502 can strike the probe 2.

[0024] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the probe 2 is first inserted into the support cylinder 1. A measuring cake 101 is installed at the bottom of the support cylinder 1. The measuring cake 101 allows the support cylinder 1 and the probe 2 to be stably placed on top of the sediment. After placement, the pressure plates 4 on both sides of the probe 2 are pressed to allow it to enter the probe 2. A gravity block 201 is installed at the top of the probe 2. After the pressure plate 4 enters the probe 2, the probe 2 will move downward under the action of the gravity block 201 to complete the detection work. A striking element 502 is installed inside the probe 2. A worm gear 503 is installed on the top of the multiple striking elements 502. A worm 504 is fitted on the surface of the worm gear 503. A gear 505 is installed at one end of the worm 504, and the gear 505 engages with a rack 506 on one side inside the support cylinder 1. The mechanism is designed so that when the probe 2 drives the gear 505 to move downward, the striking element 502 can rotate. Since the striking element 502 is in contact with the probe 2, it can strike the probe 2 when it rotates, thereby generating vibration. This vibration can make the sediment accumulate more evenly, reducing the occurrence of detection errors. Two locking plates 304 are installed inside the test cake 101, and both locking plates 304 cooperate with the locking groove 203 on the surface of the probe 2. Because of the design of the locking groove 203, the probe 2 can be moved downward normally. However, when the probe 2 moves upward, the locking plate 304 will restrict the probe 2 through the locking groove 203, so that it cannot move upward. Since the probe 2 cannot move upward alone, when it is picked up, it can be moved upward together with the test cake 101, so as to avoid the user having to enter the foundation to remove the test cake 101.
