[0024] The following is a detailed description of a high-precision cement density automatic measuring device provided by the present invention in conjunction with the accompanying drawings and specific embodiments; at the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art may also adopt other alternative methods.
[0025] like Figures 1 to 4 As shown, the embodiment of the present invention provides a high-precision cement density automatic measuring device, including a main body 1, a sliding cover 2 is slidably connected to the top of the main body 1, and a sliding groove 3 is opened on both sides of the sliding cover 2. Both sides of the top of the inner cavity of the main body 1 are fixedly connected with a clamping strip 7 adapted to the sliding groove 3. The interior of the main body 1 is fixedly connected with a heating tube 12, whose threads are distributed inside the main body 1. The ends of the two clamping strips 7 close to each other are rollingly connected with a plurality of balls 8. The inner side of the sliding groove 3 is provided with a rolling groove 4 adapted to the balls 8. The top of the sliding cover 2 is fixedly connected with a push handle. The main body 1 A water tank 9 is fixedly connected to one side of the body 1, a water pump 10 is fixedly connected to the top of the water tank 9, a heater is fixedly connected to the inside of the water tank 9, the input end of the water pump 10 is fixedly connected to a water pipe, the other end of the water pipe extends to the bottom of the inner cavity of the water tank 9, the output end of the water pump 10 is fixedly connected to an input pipe 11, the other end of the input pipe 11 extends to the inside of the main body 1, and is fixedly connected to one end of the heating pipe 12 at the top, the end of the heating pipe 12 at the bottom is fixedly connected to an output pipe 13, the other end of the output pipe 13 passes through the main body 1 and extends to the inside of the water tank 9.
[0026] Add kerosene to the density bottle and place it inside the main body 1. Slide the slide cover 2 along the slide groove 3 through the push handle, close the slide cover 2, heat the water inside the water tank 9 to a suitable temperature through the heater, and then start the water pump 10. Transport the water to the heating pipe 12 through the water pipe and the input pipe 11, and heat the inner cavity of the main body 1 through the heating pipe 12 to form a constant temperature environment inside. Then the water flows back to the water tank 9 from the output pipe 13 to realize water circulation.
[0027] The sliding cover 2 cooperates closely with the card strip 7 on the main body 1 through the sliding grooves 3 on both sides thereof, achieving smooth and stable sliding. The heating tube 12 is cleverly arranged inside the main body 1. Through the evenly distributed design, it can achieve precise temperature control of the environment around the cement sample, effectively simulate or achieve the required test temperature conditions, and construct a constant temperature, closed and stable test space, which provides a solid hardware foundation for the accurate determination of cement density, not only improving the accuracy and reliability of the test results, but also reducing energy consumption and costs during the test process.
[0028] like Figures 1 to 5 As shown, the bottom of the sliding cover 2 is fixedly connected with a fixing block 5 and a fixing component 6. The fixing component 6 is used to fix the sliding cover 2. The fixing component 6 is connected to the fixing block 5. The fixing component 6 includes a mounting plate 601 fixedly connected to the fixing block 5. The outer side of the mounting plate 601 is fixedly connected with several fixing spring pieces 602. The inner side of the fixing spring piece 602 is fixedly connected with a reinforcing spring piece 603. The end of the fixing spring piece 602 away from the mounting plate 601 is fixedly connected with a connecting ring 604. There are five fixing spring pieces 602, and they protrude outward. The middle part of the fixing spring piece 602 is a semicircular shape protruding outward. The reinforcing spring piece 603 is a shape protruding inward. The five fixing spring pieces 602 are fixedly connected to the outside of the same connecting ring 604. The inner wall of the main body 1 is provided with an annular groove whose position is adapted to the bottom end of the fixing block 5, and the inner side of the annular groove is provided with a fixing groove adapted to the fixing spring piece 602.
[0029] After a period of time, the sliding cover 2 is pushed open by the push handle, so that the fixed groove squeezes the fixed spring piece 602, causing it to deform inward until it is out of the fixed groove, completing the unlocking of the sliding cover 2. Then, the sliding cover 2 is slid open, the kerosene scale is observed, and a certain amount of cement is added to the density bottle. Then, the sliding cover 2 is closed and the appropriate time is waited. Since the internal temperature is higher than the external temperature, the air brought into the density bottle when the cement is added can be urged to move upward and then out of the density bottle, avoiding affecting the detection accuracy. Then, the sliding cover 2 is opened and the kerosene scale is observed again. The density data of the cement is obtained based on the difference between the two scales.
[0030] The fixing spring piece 602 is designed with a semicircular protrusion in the middle, which can naturally coincide with the fixing groove on the inner wall of the main body 1 during the closing process, forming a double locking mechanism, which not only ensures the stability of the sliding cover 2 in the vertical direction, but also increases the contact area through the semicircular curved contact, improves the sealing performance, and effectively prevents the leakage of air or heat. The reinforcing spring piece 603 adopts an inwardly protruding shape and is combined with the fixing spring piece 602 to form a double support structure, which not only enhances the overall strength and rigidity of the fixing spring piece 602, but also enables the fixing spring piece 602 to disperse the force more evenly when subjected to force, avoiding damage or deformation caused by excessive force on a single point, extending the service life of the fixing component 6, reducing maintenance costs, and improving the overall economy and reliability of the equipment. It also enables the fixing spring piece 602 to fit the fixing groove more closely, further improving the stability of the sliding cover 2, and ensuring that the sliding cover 2 can remain stable and motionless even in complex or harsh test environments.
[0031] The working principle of the utility model is as follows: add kerosene to the density bottle, put it into the main body 1, slide the slide cover 2 along the slide groove 3 by pushing the handle, close the slide cover 2, heat the water inside the water tank 9 to a suitable temperature by the heater, and then start the water pump 10, transport the water to the heating pipe 12 through the water pipe and the input pipe 11, and heat the inner cavity of the main body 1 through the heating pipe 12 to form a constant temperature environment inside the main body 1, and then the water flows back to the water tank 9 from the output pipe 13 to realize water circulation. After a period of time, the slide cover is pushed open by pushing the handle. 2, so that the fixed groove squeezes the fixed spring piece 602, causing it to deform inward until it is released from the fixed groove, completing the unlocking of the sliding cover 2. Then, slide the sliding cover 2 open, observe the kerosene scale, add a certain amount of cement into the density bottle, and then close the sliding cover 2. Wait for a suitable time. Because the internal temperature is higher than the external temperature, the air brought into the density bottle when the cement is added can be urged to move upward and then release from the density bottle, avoiding affecting the detection accuracy. Then, open the sliding cover 2, observe the kerosene scale again, and obtain the density data of the cement based on the difference between the two scales.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
