Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, and particularly relates to a protection device for a gravity prospecting instrument. Background Art

[0002] Gravity prospecting is one of the geophysical prospecting methods. It is a method of geological exploration using the gravity changes caused by the density differences of various rock and ore bodies composing the earth's crust. It is based on Newton's law of universal gravitation. As long as the exploration geological body has a certain residual mass, a relatively small burial depth, and a relatively small influence of terrain undulation, the gravity anomaly can be measured by a precision gravity instrument. Then, combined with the geological data of the working area, qualitative or quantitative interpretation of the gravity anomaly can be carried out, and the burial conditions of ore bodies and rock layers with different densities below the overburden can be inferred, so as to find the location of the rock and ore bodies and the geological structure; during the transportation process, the gravity prospecting instrument is usually loaded in a box and then transported. During the transportation process, it often collides with the inner wall of the box, resulting in damage to the appearance or internal damage of the gravity prospecting instrument, affecting people's use. Content of the Utility Model

[0003] The purpose of the utility model is to provide a protection device for a gravity prospecting instrument to solve the above deficiencies in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a protection device for a gravity prospecting instrument, comprising: a box body, a box cover is rotatably arranged at the top end of the box body, a bidirectional screw rod is rotatably arranged in the box body, two clamping plates moving towards each other are threadedly connected to the outside of the bidirectional screw rod, a push rod is fixedly connected to the outside of the clamping plate, a negative pressure groove is formed in the box body, a sliding sleeve communicating with the negative pressure groove is fixedly connected to the inner wall of the box body, the push rod is slidably arranged in the sliding sleeve through a piston head, a cylindrical silica gel plug is fixedly connected to the box cover, and when the box cover is closed, the cylindrical silica gel plug is inserted into the negative pressure groove.

[0005] Further, a snap spring is clamped in the negative pressure groove.

[0006] Further, a support plate is fixedly connected to the middle and lower position of the inner side of the clamping plate.

[0007] Further, a plurality of vertically arranged rubber strips are fixedly connected to the inner side of the clamping plate.

[0008] Further, a hexagonal groove is formed at one end of the bidirectional screw rod passing through the box body.

[0009] Further, a slider is fixedly connected to the inner side of the box cover through a spring, and a rubber gasket is fixedly connected to the lower end of the slider.

[0010] In the above technical solution, the beneficial effects of a protection device for a gravity prospecting instrument provided by the present utility model are as follows:

[0011] By rotating the bidirectional screw rod, the two clamping plates approach or move away from each other, and the gravity prospecting instrument can be clamped according to its size. When the two clamping plates approach each other to clamp the gravity prospecting instrument, the clamping plate drives the piston head to slide inward, so that a negative pressure is formed in the negative pressure groove, and the cylindrical silica gel plug is tightly adsorbed in the negative pressure groove, thereby strengthening the locking effect between the box body and the box cover, ensuring that the gravity prospecting instrument is firmly fixed in the box body, reducing the risk of damage to the gravity prospecting instrument caused by impact, increasing the service life, and being beneficial to use.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts fall within the scope of protection of the present disclosure.

[0021] Please refer to FIGS. 1-3. A protection device for a gravity prospecting instrument includes: a box body 1, a box cover 2 is rotatably provided at the top of the box body 1, a bidirectional screw 5 is rotatably provided inside the box body 1, two clamping plates 3 moving towards each other are threadedly connected to the outside of the bidirectional screw 5, the two clamping plates 3 are symmetric about the axis of the box body 1, and the thread directions of the two sections on the clamping plate 3 are opposite, so that when the bidirectional screw 5 rotates, the two clamping plates 3 approach or move away from each other. A push rod 8 is fixedly connected to the outside of the clamping plate 3, and the push rod 8 is located at a position slightly above the middle of the clamping plate 3. A negative pressure groove 12 is formed inside the box body 1, and a sliding sleeve 11 communicating with the negative pressure groove 12 is fixedly connected to the inner wall of the box body 1. The sliding sleeve 11 is welded to the inner wall of the box body 1. The push rod 8 is slidably provided in the sliding sleeve 11 through a piston head 81. A piston head 81 is fixedly connected to the end of the push rod 8. A cylindrical silicone plug 9 is fixedly connected to the box cover 2, and the cylindrical silicone plug 9 is located inside the box cover 2. When the box cover 2 is closed, the cylindrical silicone plug 9 is inserted into the negative pressure groove 12.

[0022] Specifically, referring to Figures 1 to 3 , first, according to the size of the gravity prospecting instrument, rotate the bidirectional screw 5 to adjust the distance between the two clamping plates 3, place the gravity prospecting instrument between the two clamping plates 3 inside the box body 1, and close the box cover 2 so that the cylindrical silicone plug 9 is inserted into the negative pressure groove 12. Subsequently, rotate the bidirectional screw 5 so that the two clamping plates 3 approach each other to clamp the gravity prospecting instrument. At the same time, referring to Figure 3 , the piston head 81 slides to the left inside the sliding sleeve 11, making the internal space of the negative pressure groove 12 and the sliding sleeve 11 larger, so that a negative pressure is formed between the sliding sleeve 11 and the negative pressure groove 12, adsorbing the cylindrical silicone plug 9 in the negative pressure groove 12 and enhancing the locking effect between the box body 1 and the box cover 2.

[0023] In the present utility model, by rotating the bidirectional screw 5, the two clamping plates 3 can approach or move away from each other, and can be clamped according to the size of the gravity prospecting instrument. When the two clamping plates 3 approach each other to clamp the gravity prospecting instrument, the clamping plate 3 drives the piston head 81 to slide inward, so that a negative pressure is formed in the negative pressure groove 12, and the cylindrical silicone plug 9 is tightly adsorbed in the negative pressure groove 12, thereby strengthening the locking effect between the box body 1 and the box cover 2, ensuring that the gravity prospecting instrument is firmly fixed in the box body 1, reducing the risk of damage to the gravity prospecting instrument due to impact, increasing the service life, and being beneficial to use.

[0024] Furthermore, a snap ring 10 is clamped inside the negative pressure groove 12.

[0025] Specifically, referring to Figure 3 , the snap ring 10 is clamped in a ring groove formed on the inner wall of the negative pressure groove 12, which is used to prevent the cylindrical silica gel plug 9 from being excessively deformed under negative pressure, ensuring that the negative pressure groove 12 maintains a certain adsorption strength on the cylindrical silica gel plug 9.

[0026] Furthermore, a support plate 4 is fixedly connected to the middle and lower position on the inner side of the clamping plate 3.

[0027] Specifically, referring to Figure 2 , the support plate 4 is welded to the inner side of the clamping plate 3 and is located above the bidirectional screw 5. The two support plates 4 serve as load-bearing plates of the gravity prospecting instrument.

[0028] Furthermore, a plurality of vertically arranged rubber strips 31 are fixedly connected to the inner side of the clamping plate 3.

[0029] Specifically, referring to Figure 2 , by fixedly connecting a plurality of rubber strips 31 to the inner side of the clamping plate 3, when the two clamping plates 3 clamp the gravity prospecting instrument, the rubber strips 31 are deformed, increasing the friction force between the clamping plate 3 and the gravity prospecting instrument, making the clamping stability better.

[0030] Furthermore, a hexagonal notch 51 is formed at one end of the bidirectional screw 5 passing through the box body 1.

[0031] Specifically, referring to Figure 1 , one end of the bidirectional screw 5 is rotatably arranged on the inner wall of the box body 1, and the other end of the bidirectional screw 5 passes through the box body 1 and a hexagonal notch 51 is formed thereon. By forming a hexagonal notch 51 at the end of the bidirectional screw 5, it is convenient for the staff to control the rotation of the bidirectional screw 5 using a handle.

[0032] Furthermore, a slider 6 is fixedly connected to the inner side of the box cover 2 through a spring 7, and a rubber gasket 61 is fixedly connected to the lower end of the slider 6.

[0033] Specifically, referring to Figure 1 , one end of the spring 7 is fixedly connected to the inner side of the box cover 2, and the other end of the spring 7 is fixedly connected to the top of the slider 6. When the box cover 2 is rotated so that the box cover 2 covers the box body 1, the rubber gasket 61 is in pressing contact with the top of the gravity prospecting instrument, causing the slider 6 to retract against the elastic force of the spring 7. Then, after the gravity prospecting instrument is placed in the box body 1, the gravity prospecting instrument is limited by the elastic force of the spring 7 between the box cover 2, preventing the gravity prospecting instrument from hitting the inner wall of the box during transportation.

[0034] In the present utility model, referring to Figures 1 to 3, first, according to the size of the gravity prospecting instrument, rotate the bidirectional screw 5 to adjust the distance between the two clamping plates 3, place the gravity prospecting instrument between the two clamping plates 3 in the box body 1, and close the box cover 2. The rubber gasket 61 is in extrusion contact with the top of the gravity prospecting instrument, so that the slider 6 retracts against the elastic force of the spring 7. Then, after the gravity prospecting instrument is placed in the box body 1, the gravity prospecting instrument is limited by the elastic force of the spring 7 between the box body 1 and the box cover 2. Then, the cylindrical silicone plug 9 will be inserted into the negative pressure groove 12. Immediately afterwards, rotate the bidirectional screw 5 to make the two clamping plates 3 approach each other to clamp the gravity prospecting instrument. At the same time, refer to Figure 3 , the piston head 81 slides to the left in the sliding sleeve 11, making the internal space of the negative pressure groove 12 and the sliding sleeve 11 larger, so that a negative pressure is formed between the sliding sleeve 11 and the negative pressure groove 12, adsorbing the cylindrical silicone plug 9 in the negative pressure groove 12 and enhancing the locking effect between the box body 1 and the box cover 2.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
