Description

Technical Field

[0001] This utility model belongs to the technical field of performance testing of demolition tools, and specifically relates to a performance testing device for underwater demolition tools. Background Technology

[0002] In scenarios such as underwater rescue, underwater engineering maintenance, and underwater emergency response, underwater demolition tools (such as jacking devices) play a crucial role. Their performance stability, lifting force output accuracy, and displacement control accuracy are directly related to operational safety and mission success. Compared to the land environment, the underwater environment has unique characteristics such as high pressure, water flow interference, and limited visibility. The actual working performance of underwater demolition tools differs significantly from the land test results. Therefore, it is particularly necessary to conduct targeted underwater performance tests on them.

[0003] Currently, performance testing of existing demolition tools is mostly concentrated in terrestrial environments, lacking dedicated underwater performance testing equipment, making it difficult to realistically simulate underwater working conditions. Furthermore, some existing simple underwater testing devices have certain shortcomings: First, the tool fixing mechanism is poorly designed, often using rigid clamping methods, which cannot adapt to various specifications of support devices. This makes it easy for different support devices to shift under high-pressure underwater conditions, affecting test accuracy. Second, the placed heavy components are prone to slipping, and it is difficult to adjust to different load levels, making it impossible to comprehensively test the performance of the support device under different loads. Utility Model Content

[0004] The purpose of this invention is to provide a performance testing device for underwater demolition tools to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an underwater demolition tool performance testing device, comprising a test water tank, a fixing mechanism installed in the test water tank, the fixing mechanism being used to limit the support device, a pressure detection component installed in the test water tank, a pressure sensor in the pressure detection component being fixedly installed on the lifting end of the support device, the lifting end of the support device also supporting a bearing mechanism, different weight components being placed on the bearing mechanism, and a displacement detection component being fixedly installed on one side of the top of the test water tank.

[0006] In a preferred embodiment, the fixing mechanism includes a first clamping block, a second clamping block, and an electric telescopic push rod. The first clamping block is fixedly installed on the inner bottom wall of the test water tank. One end of the second clamping block is connected to the telescopic output end of the electric telescopic push rod. The electric telescopic push rod is arranged on the outer side wall of the test water tank, and its telescopic output end penetrates the side wall of the test water tank after being sealed.

[0007] In a preferred embodiment, the first clamping block and the second clamping block are specifically designed with a V-shaped structure.

[0008] In a preferred embodiment, the pressure detection component further includes a data acquisition module, which is connected to a waterproof wire, the other end of which is electrically connected to a pressure sensor.

[0009] In a preferred embodiment, the bearing mechanism includes a support frame with a rectangular cavity. A support plate is placed on the support frame, and an inner groove is formed on the support plate. A weight component is embedded in the inner groove. The weight component includes a first weight block, a second weight block, and a third weight block. Each of the three weight blocks has a corresponding slot, and the three weight blocks are placed in their slots in a stacked manner from top to bottom.

[0010] In one preferred embodiment, the support plate is fixedly connected to four downwardly extending guide posts at its four ends, and the guide posts pass through the perforations reserved at the four corners of the support frame.

[0011] In a preferred embodiment, the displacement detection assembly includes a laser displacement sensor, which is fixedly mounted on the top of the test water tank by a side bracket.

[0012] In a preferred embodiment, a scale is installed on the inner wall of the test water tank, and a water supply pipe is also connected to the side wall of the test water tank, with a drain valve installed on the water supply pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The underwater demolition tool performance testing device adopts a structure design of a first clamping block and a second clamping block in conjunction with an electric telescopic push rod through a fixing mechanism. Both clamping blocks are V-shaped structures. Compared with the rigid clamping method in the prior art, the V-shaped structure can expand the adaptability range by contacting and adhering to the side wall of various different specifications of support devices through surface contact, ensuring that the support device does not shift under the high pressure environment underwater. This underwater demolition tool performance testing device uses a support plate with recessed weights embedded in the support plate. It also features a stacked weight block design with slots and guide pillars at the four ends of the support plate. This design avoids the risk of weight slippage and allows for flexible adjustment of the load level by adding or removing different weight blocks. This enables comprehensive testing of the support device's performance under different loads, effectively overcoming the shortcomings of existing support mechanisms, such as simple structure, inconvenient load adjustment, and incomplete testing.

Detailed Implementation

[0016] The present invention will be further described below with reference to the embodiments.

[0017] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0018] Please see Figures 1 to 4 This utility model provides an underwater demolition tool performance testing device, including a test water tank 1, a fixing mechanism 2 installed in the test water tank 1, the fixing mechanism 2 being used to limit the support device 3, a pressure detection component 4 also installed in the test water tank 1, a pressure sensor 41 in the pressure detection component 4 being fixedly installed on the lifting end of the support device 3, the lifting end of the support device 3 also supporting a bearing mechanism 5, on which different weight components are placed, and a displacement detection component 7 is also fixedly installed on one side of the top of the test water tank 1.

[0019] In this embodiment, by combining the design of the fixing mechanism 2, it can be adapted to the stable clamping and limiting of various specifications of the support device 3. In addition, by combining the test water tank 1 to simulate the underwater environment and using the weight block to provide load, and with the use of the pressure detection component 4 and the displacement detection component 7, it is possible to obtain key performance parameters such as the lifting force and lifting displacement of the support device 3 underwater.

[0020] Please see Figure 2 and Figure 3The fixing mechanism 2 includes a first clamping block 21, a second clamping block 22, and an electric telescopic push rod 23. The first clamping block 21 is fixedly installed on the inner bottom wall of the test water tank 1. One end of the second clamping block 22 is connected to the telescopic output end of the electric telescopic push rod 23. The electric telescopic push rod 23 is arranged on the outer side wall of the test water tank 1. Its telescopic output end is sealed and penetrates through the side wall of the test water tank 1. In addition, the first clamping block 21 and the second clamping block 22 are specifically designed with a V-shaped structure.

[0021] In this embodiment, the V-shaped first clamping block 21 and second clamping block 22 are used to contact and fit the side wall of the support 3 of different specifications. This allows for the adaptation of multiple models without replacing the clamping blocks, thus solving the problem of the narrow adaptation range of existing rigid clamping.

[0022] Please see Figures 1 to 3 The pressure detection component 4 also includes a data acquisition module 43, which is connected to a waterproof wire 42. The other end of the waterproof wire 42 is electrically connected to the pressure sensor 41.

[0023] In this embodiment, the pressure sensor 41 and the data acquisition module 43 are electrically connected through the waterproof wire 42, which can transmit the pressure data of the lifting end of the support device 3 in real time, providing accurate data support for performance evaluation and making up for the defect of unreliable pressure data acquisition in existing underwater tests.

[0024] Please see Figures 2 to 4 The supporting mechanism 5 includes a support frame 51 with a rectangular cavity. A support plate 52 is placed on the support frame 51 with an inner groove 521. A weight component is embedded in the inner groove 521. The weight component includes a first weight block 6, a second weight block 61, and a third weight block 62. The corresponding positions of the three weight blocks are provided with slots, and the three weight blocks are placed in their slots in a stacked manner from top to bottom. The four ends of the support plate 52 are fixedly connected with downwardly extending guide posts 53, which pass through the pre-reserved holes at the four corners of the support frame 51.

[0025] In this embodiment, the inner groove 521 on the support plate 52 can initially limit the weight of the component. Combined with the slot design of the corresponding positions of the three sets of weight blocks, a nested stacking from top to bottom can be achieved, so that the weight blocks can form a mechanical interlock. Combined with the guiding constraint of the guide posts 53 at the four ends of the support plate 52 and the through holes of the support frame 51, the lateral displacement and longitudinal sway of the weight of the component during the underwater test can be limited, which solves the problem of the weight of the component easily slipping off in the traditional bearing mechanism 5.

[0026] Please see Figure 1 and Figure 3 The displacement detection component 7 includes a laser displacement sensor 71, which is fixedly mounted on the top of the test water tank 1 by a side bracket 72.

[0027] In this embodiment, the laser displacement sensor 71 enables real-time acquisition and transmission of displacement data, which can be synchronized with the data from the pressure detection component 4 to record the pressure-displacement changes of the support device 3 under different loads. This provides comprehensive data support for the underwater performance evaluation of the support device 3 and improves the scientific rigor and efficiency of the test analysis.

[0028] Please see Figure 1 and Figure 2 The inner wall of the test water tank 1 is equipped with a scale 8, and the side wall of the test water tank 1 is also connected to a water supply pipe 11, on which a drain valve 12 is installed.

[0029] In this embodiment, the scale 8 on the inner wall of the test water tank 1 can intuitively display the water level in the tank. With the water supply pipe 11 and the drain valve 12 connected to the side wall, water can be injected or discharged as needed to achieve different water depth environments.

[0030] Working principle and usage process of this utility model: During operation, the support device 3 is first placed in the test water tank 1, and the electric telescopic push rod 23 is activated to push the V-shaped second clamping block 22 to move, which cooperates with the fixed first clamping block 21 to achieve stable clamping of various different specifications of support devices 3. Water is then injected into the water tank through the water supply pipe 11, and the water depth is adjusted to the target value according to the scale 8 on the inner wall to simulate the corresponding underwater pressure environment. According to the test requirements, multiple sets of weight blocks with slots are nested from top to bottom in the inner groove 521 of the support plate 52. The guide post 53 passes through the perforation of the support frame 51 to ensure the stability of the weight components. Then, the jacking device 3 is started to lift. The pressure sensor 41 collects the lifting pressure data in real time and transmits it to the data acquisition module 43 via the waterproof wire 42. At the same time, the laser displacement sensor 71 at the top of the test water tank 1 synchronously detects the lifting displacement of the bearing mechanism 5. The pressure-displacement data of the support device 3 under different loads is obtained by stacking multiple weight blocks of different weights to complete the performance test. After the test, the drain valve 12 is opened to empty the water tank.

[0031] In the above scheme, it should be noted that: the electric telescopic push rod 23, the support device 3, the pressure sensor 41, the data acquisition module 43, and the laser displacement sensor 71 in this application are all existing products, and the specific structure, circuit layout, and working principle of the electric telescopic push rod 23, the support device 3, the pressure sensor 41, the data acquisition module 43, and the laser displacement sensor 71 are all existing publicly disclosed technical means, and will not be described in detail here. At the same time, the pressure detection principle and method of the pressure sensor 41, and the displacement detection principle and method of the laser displacement sensor 71 are also existing publicly disclosed technical means, and will not be described in detail here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
