Description

Technical Field

[0001] The utility model relates to the technical field of refrigerant gas tank detection, and in particular to a detection device for a refrigerant gas tank. Background Art

[0002] Refrigerant gas tank inspection is an important process that ensures the integrity and safety of refrigerant gas tanks and prevents accidents such as leakage or explosion during storage, transportation and use. Refrigerant gas tanks are usually used to store and transport various refrigerants, such as Freon and other types of refrigerants. Therefore, in order to ensure the safety and reliability of refrigerant gas tanks, regular sealing performance tests are required.

[0003] Among them, the immersion method is a commonly used detection method, which is suitable for detecting the air tightness of the gas tank as a whole or any part. First, the gas tank is filled with compressed gas of a specified pressure, and then the inflated gas tank is immersed in a water tank to carefully observe whether there are bubbles on the surface of the gas tank. If bubbles are emitted, it means that the gas tank is leaking; however, in the prior art, when the water immersion method is used to detect the sealing performance of the refrigerant gas tank, the gas tank is usually directly placed in water. When the gas tank is taken out of the water, a large amount of water will adhere to its surface, and this water may drip onto the ground in the working area, causing slippery conditions and increasing safety hazards.

[0004] Therefore, in view of the above problems, it is urgent to propose a detection device for a refrigerant gas tank that can prevent the attached water from falling off when taking it out. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the technical problem of the utility model is to provide a detection device for a refrigerant gas tank which can prevent attached water from falling off when taking out.

[0006] A detection device for a refrigerant gas cylinder comprises a bracket, a water storage frame, a mounting block, an electric push rod, a mounting plate, a placement ring, an air pipe, a fixing plate, a diversion chamber, a fan and a connecting pipe. A water storage frame is arranged on the top of the bracket, at least two mounting blocks are arranged at intervals on the rear side of the water storage frame, electric push rods with telescopic ends facing upward are mounted on the mounting blocks, a mounting plate is arranged on the telescopic end of the electric push rod, at least two placement rings for placing the gas cylinder are arranged at intervals on the bottom of the mounting plate, an air pipe coaxial with the placement ring is arranged on the mounting plate, one end of the air pipe close to the placement ring is used to connect to the gas cylinder, and the other end is used to connect to a filling device; a fixing plate is arranged on the top of the mounting plate, a diversion chamber is arranged on the top of the fixing plate, a fan located on the rear side of the diversion chamber is arranged on the top of the mounting plate, and a connecting pipe is connected between the fan and the diversion chamber.

[0007] Further description, it also includes a correction rod, an elastic part, a limit frame and a clamping rod. The inner walls on both sides of the placement ring are slidably provided with a correction rod, an elastic part is provided between the correction rod and the adjacent side wall of the placement ring, and a limit frame is slidably provided between the lower side of the placement ring, and a clamping rod is inserted between the limit frame and the plate part of the placement ring.

[0008] Further description, it also includes a telescopic load-bearing rod, and the mounting block is provided with a telescopic load-bearing rod whose telescopic end is connected to the mounting plate on the same side.

[0009] Further description, it also includes a partition plate, and the internal interval of the water storage frame is provided with a partition plate whose number is one less than the number of the electric push rods.

[0010] Further explanation, it also includes a pulley, and the end of the correction rod facing each other and the top end of the limit frame that penetrates the plate body are both rotatably provided with pulleys.

[0011] It is further explained that the two sides of the diversion chamber are in a close-to-close and inclined state.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model drives the mounting plate to move up and down through an electric push rod, so that the water immersion detection of the gas cylinder can be automatically operated. Moreover, when the gas cylinder is taken out after the inspection, the gas cylinder with moisture attached can be parked above the water storage frame and blown dry with the wind of the fan and the diversion chamber, so that the gas cylinder can have suitable space and suitable conditions for draining, so as to avoid the situation that water is scattered when it is taken out, which provides a guarantee for the safety of the inspection work.

[0013] 2. The utility model makes the placement of the gas tank more flexible and stable through the setting of the correction rod and the limit frame, which can not only assist the movement of the gas tank, but also assist in the positioning of the gas tank, ensuring that the gas tank remains in a stable state during the detection process, and further improving the accuracy and reliability of the detection.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0020] Embodiment: A detection device for a refrigerant gas tank, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a water storage frame 2, a mounting block 3, an electric push rod 4, a mounting plate 5, a placement ring 6, an air pipe 7, a fixing plate 12, a diversion chamber 13, a fan 14 and a connecting pipe 15. The bracket 1 serves as the basic supporting structure of the entire detection device. A water storage frame 2 is arranged on the top of the bracket 1. The water storage frame 2 is used to temporarily store water for detection and can collect water dripping from the gas tank during the detection process. Three mounting blocks 3 are arranged at intervals on the rear side of the water storage frame 2. Electric push rods 4 with telescopic ends facing upwards are installed on the mounting blocks 3. A mounting plate 5 is arranged on the telescopic end of the electric push rod 4. The mounting plate 5 is in a state of extending forward to facilitate the installation of subsequent parts. Three placement rings 6 for placing gas tanks are arranged at intervals on the bottom of the mounting plate 5. The arrangement of the placement ring 6 makes it more convenient to place the gas tank during detection, further simplifies the operation steps, and the mounting plate 5 is provided with a placement ring 6. An air supply pipe 7 is arranged cocentrically with the placement ring 6, and one end of the air supply pipe 7 close to the placement ring 6 is used to connect to the gas tank, and the rear end is used to connect to the filling equipment. It is an important connector to ensure the normal operation of the detection operation. The front and rear ends respectively present different connection end faces, which are adapted to the different connection methods in the above two situations; a fixed plate 12 is arranged on the top of the mounting plate 5, and a diversion chamber 13 is arranged on the top of the fixed plate 12. The left and right sides of the diversion chamber 13 are in a close-to-closed inclined state, which can guide the wind flow, thereby evenly distributing the wind force to ensure that the moisture can be dried faster. A fan 14 is arranged on the top of the mounting plate 5 and is located on the rear side of the diversion chamber 13. A connecting pipe 15 is connected between the fan 14 and the diversion chamber 13. The fan 14 can infuse air flow into the diversion chamber 13 through the connecting pipe 15, thereby transporting the wind force to the surface of the gas tank and drying the moisture on its surface.

[0021] like Figure 3As shown, it also includes a correction rod 8, an elastic member 9, a limit frame 10 and a clamping rod 11. The inner walls on both sides of the placement ring 6 are both slidably provided with a correction rod 8, and an elastic member 9 is provided between the correction rod 8 and the adjacent side wall of the placement ring 6. In this embodiment, the elastic member 9 is a spring, which is used to provide a rebound force for the movement of the correction rod 8, and a limit frame 10 is slidably provided between the lower sides of the placement ring 6. The lower part of the limit frame 10 is an elongated plate body along the front and rear directions, and the limit frame 10 passes through the plate body part of the placement ring 6, presenting a spaced small plate body with the same number as the placement ring 6, and a clamping rod 11 is inserted between the spaced small plate bodies. In addition, holes that are compatible with the clamping rod 11 are spaced apart on the spaced small plate bodies, so that the limit frame 10 can be moved to different positions as needed, and fixed by inserting the clamping rod 11 into the holes at the corresponding positions, so as to adapt to gas tanks of different sizes.

[0022] like Figure 2 As shown, a telescopic load-bearing rod 16 is also included. The mounting block 3 is provided with a telescopic load-bearing rod 16 whose telescopic end is connected to the mounting plate 5 on the same side, which can bear part of the load for the electric push rod 4 to increase the stability of the device.

[0023] like Figure 1 As shown, a partition plate 17 is also included. The internal interval of the water storage frame 2 is provided with one less partition plate 17 than the number of the electric push rods 4, which is used to separate the space of the water storage frame 2, thereby separating the positions of different detection gas tanks to avoid affecting the detection accuracy.

[0024] like Figure 3 As shown, a pulley 18 is also included. The end of the correction rod 8 facing each other and the top of the limit frame 10 that penetrates the plate body are both rotatably provided with a pulley 18 for reducing the friction between the gas tank and the correction rod 8 or the limit frame 10, and assisting the movement of the gas tank.

[0025] When the device needs to be used, first ensure that the bracket 1 is placed on a stable working surface, then fill the water storage frame 2 with test water, and then, according to the size of the test gas tank, push the limit frame 10 to slide up and down on the placement ring 6, so as to adjust it to the required placement position for the gas tank. After the adjustment is completed, the insertion rod is inserted into the lowermost hole of the limit frame 10 located in the inner part of the placement ring 6 to fix the position of the limit frame 10, and then the gas tank to be tested is passed through the placement ring 6, so that the left and right sides and the lower side of the gas tank are respectively in contact with the pulleys 18 on the correction rod 8 and the limit frame 10, and the pulley 18 assists the gas tank to cross the placement ring 6. In this process, the correction rod 8 is squeezed by the gas tank, and the correction rod 8 is pushed by force to slide in the direction away from the side of the placement ring 6, and the connected elastic member 9 is deformed accordingly, so that the correction rod 8 can maintain contact with the surface of the gas tank, thereby forming an auxiliary clamping effect. When the gas tank moves to the position of the gas supply pipe 7, The gas outlet of the gas tank is connected to the gas supply pipe 7, and the other end of the gas supply pipe 7 is connected to the filling device. Then the electric push rod 4 is started, and the mounting plate 5 and its upper parts are driven to move downward by the electric push rod 4. The telescopic end of the telescopic load-bearing rod 16 operates synchronously, thereby driving the gas tank to move downward and enter the water storage frame 2. At the same time, the partition plate 17 separates the positions of each gas tank. When the gas tank is immersed in water, the filling device is started to fill the gas tank with gas to detect the air tightness of the gas tank. After the detection is completed, the electric push rod 4 is started to move up and reset, so that the gas tank is suspended above the water storage frame 2, and then it is left to stand for treatment. The moisture attached to the gas tank will fall into the water storage frame 2. In this process, the fan 14 is started, and the air flow is poured into the connecting pipe 15 through the fan 14. The air flow then flows into the diversion chamber 13 and is discharged downward from both sides to dry the surface moisture of the gas tank, thereby achieving the effect of assisting in removing moisture, so as to avoid the situation where too much moisture attached to the gas tank falls and affects the working environment when taking out the gas tank.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
