Especially for pressure gauges used in special occasions, the accuracy of the measured values ​​is very important, and they are generally tested by full inspection. For underwater pressure gauges, it is necessary to simulate the underwater environment during testing. The pressure gauge is installed in a closed container and water is injected into the closed container. The upper surface of the water is higher than the pressure gauge and lower than the top surface of the container.

At present, when installing the pressure gauge, this equipment directly places the pressure gauge in the corresponding metal placement groove. The size of the placement groove matches the outer size of the pressure gauge. The outer shell of the pressure gauge is prone to mechanical collision with the wall of the placement groove, resulting in scratches or pits, affecting the surface quality of the pressure gauge.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] It should be noted that, in the description of the technical solution of the present invention, some directional words used to clearly describe the technical features of the present invention, such as "front", "back", "up", "down", "top", "bottom", "inside", "outside", etc., are all in accordance with the orientation of the drawings of the present invention.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a detection device for an underwater pressure gauge in this embodiment includes a control device 1 and a receiving device 2. The control device 1 is connected to the receiving device 2 through a control system. The control device 1 is connected to the internal cavity of the receiving device 2 through a pressurized pipe and a water pipe. In this embodiment, the control device 1 adopts a structure in the prior art, and the specific structure is not described in detail here. The control device 1 can pressurize or depressurize the internal cavity of the receiving device 2 through the pressurized pipe, and the control device 1 can inject or pump water into the internal cavity of the receiving device 2 through the water pipe.

[0025] The accommodating device 2 is provided with a mounting assembly, and the mounting assembly includes a base plate 3, and the base plate 3 is provided with a plurality of mounting grooves 31 for accommodating a pressure gauge and arranged side by side. In order to prevent the pressure gauge from being directly placed in the mounting groove 31 and mechanically colliding with the groove wall, a buffer sheet 4 is provided in each mounting groove 31 in this embodiment, and the buffer sheet 4 is elastically connected in the mounting groove 31 through an elastic support assembly 6, and the buffer sheet 4 is located between the mounting groove 31 and the pressure gauge, and a clearance hole 42 for accommodating the threaded tube of the pressure gauge is provided at the bottom of the buffer sheet 4. The inner diameter of the clearance hole 42 is larger than the outer diameter of the threaded tube. In a stress-free state, the buffer sheet 4 is in a separated state from the mounting groove 31 under the elastic support of the elastic support assembly 6, and the buffer sheet 4 is located in the mounting groove 31. When the pressure gauge is placed, the pressure gauge first contacts the buffer sheet 4, and the threaded tube is located in the clearance hole 42. Since the buffer plate 4 is an elastic support, the mechanical impact force when the pressure gauge contacts the buffer plate 4 will be converted into the elastic deformation force of the elastic support component 6, thereby greatly weakening the mechanical impact. When placing the pressure gauge, there is no need to be cautious due to concerns about large mechanical impact, thereby improving the installation efficiency of the pressure gauge.

[0026] When the pressure gauge is completely placed on the buffer sheet 4, the gravity of the pressure gauge is greater than the elastic force of the elastic support assembly 6, so the buffer sheet 4 will drop to the lowest displacement, that is, the outer wall of the buffer sheet 4 will fit the inner wall of the installation groove 31. With this design, the buffer sheet 4 and the installation groove 31 can jointly support the pressure gauge, and the buffer sheet 4 will not be displaced when the water pressure increases, which will affect the accuracy of the pressure gauge detection value; the structural reliability is higher.

[0027] Specifically, in this embodiment, both ends of the buffer sheet 4 are bent to form a lap portion 41, and the lap portion 41 is overlapped on the outer top of the mounting groove 31. A support platform 32 is convexly provided below one side of the mounting groove 31 on the substrate 3, and the support platform 32 extends along the circumference of the mounting groove 31 to form an arc-shaped support platform, and both ends of the support platform 32 are respectively provided with a fixing portion 321. With this structural design, the thickness of the substrate 3 is small, which can save materials and reduce costs. At the same time, a higher structural strength is achieved through the support platform 32 to ensure stability when supporting the pressure gauge. In addition, a through hole 322 connected to the clearance hole 42 is provided through the bottom of the support platform 32.

[0028] Each buffer sheet 4 is provided with two elastic support components 6, each elastic support component 6 is respectively connected between the corresponding fixed portion 321 and the overlap portion 41. The elastic support component 6 includes an inner sleeve rod 61, an outer sleeve 62 and a spring 63. The inner sleeve rod 61 is fixedly connected to the fixed portion 321, the outer sleeve 62 is fixedly connected to the overlap portion 41 of the buffer sheet 4, the spring 63 is located inside the outer sleeve 62 and sleeved on the outside of the inner sleeve rod 61, and the top end of the spring 63 abuts against the outer sleeve 62, and the bottom end of the spring 63 is fixedly connected to the inner sleeve rod 61 or abuts against the fixed portion 321. The length of the outer sleeve 62 is not less than the length of the inner sleeve rod 61. When not under stress, the outer sleeve 62 is located above the inner sleeve rod 61 under the support of the elastic force of the spring 63, and there is a certain distance between the inner top surface of the outer sleeve 62 and the top surface of the inner sleeve rod 61. When the pressure gauge is placed on the buffer sheet 4, the outer sleeve 62 overcomes the elastic force of the spring 63 under the action of the gravity of the pressure gauge and moves downward until the bottom of the outer sleeve 62 abuts against the fixing portion 321. At this time, the buffer sheet 4 is in contact with the mounting groove 31.

[0029] In addition, in order to prevent the pressure gauge from tilting and falling from one side of the mounting groove 31, a baffle 33 is provided on one side of the mounting groove 31 in this embodiment. Specifically, the baffle 33 is fixedly connected to one end of the support platform 32 away from the substrate 3. When the pressure gauge is placed in the mounting groove 31 through the buffer sheet 4, the height of the baffle 33 is higher than half of the height of the pressure gauge to ensure a reliable and stable anti-falling effect. In this embodiment, the top end of the baffle 33 is bent outward to form a transition portion 331, so that the pressure gauge can be easily placed in to avoid mechanical collision.

[0030] An end plate 5 is detachably connected at one end of the opening of the accommodating device 2 by bolts, and the end plate 5 is used to seal the opening of the accommodating device 2. The end plate 5 is fixedly connected to the base plate 3, and a slideway (not shown in the figure) is provided at the bottom of the accommodating device 2 along the length direction of the base plate 3. The bottom of the base plate 3 is slidably connected to the above slideway. The slideway adopts the structure of the prior art, and the sliding cooperation between the base plate 3 and the slideway is also a common technical means in the prior art, which will not be described in detail here. With this structural design, when the end plate 5 is moved, the base plate 3 can be driven to slide synchronously along the slideway, so as to facilitate the placement or removal of the pressure gauge.

[0031] When in use, first place the pressure gauges one by one into the installation slot 31, then push the end plate 5 to drive the base plate 3 and the multiple pressure gauges to be tested thereon to move into the interior of the receiving device 2 until the end plate 5 covers the opening of the receiving device 2 and is fastened by bolts. Then, water is poured into the receiving device 2 through the control device 1 until the water level is higher than the top of the pressure gauge to be tested, and then the water pressure in the receiving device 2 is controlled by the control device 1 to observe whether the pointer indication value of the pressure gauge to be tested is accurate under different water pressures. After the test is completed, the defective products with inaccurate indication values ​​can be picked out.

[0032] The utility model discloses an underwater pressure gauge detection device, which detects the pressure gauge by simulating underwater environments with different water pressures, and the detection result is more accurate; at the same time, the design of the buffer sheet 4 greatly reduces the mechanical impact generated when the pressure gauge is placed, and can improve the efficiency of the pressure gauge placement; the overall structure is reasonably designed, the structural strength is high, the stability is good, and the operation is convenient.

[0033] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the utility model.
