Description

Technical Field

[0001] The present invention relates to the technical field of suspense mass samplers, and in particular to a warehouse explosion protection device. Background Art

[0002] Using a pressure-regulated suspension sampler is currently the most accurate method for sampling. The design and componentry of these units are largely similar, consisting of a pressure-regulating chamber, a sampling chamber, a control chamber, and a control valve. Both the sampling and control chambers utilize a pressure-regulating system composed of the pressure-regulating chamber and the control valve for pressure regulation. During use, moisture and splashing from the pressure-regulating chamber can easily accumulate within the control chamber, potentially damaging the electrical components of the control valve. Therefore, improvements have been made to the structure, employing an airbag to regulate the pressure in the control chamber. This allows the control and sampling chambers to utilize separate pressure-regulating systems to minimize damage to the electrical components of the control valve. However, over time, the airbag can become easily damaged, potentially damaging the electrical components of the control valve within the control chamber. Summary of the Invention

[0003] In view of the above-mentioned shortcomings, the object of the present invention is to provide a chamber explosion protection device to prevent river water from entering the control chamber after the airbag is damaged.

[0004] To achieve the above purpose, the technical solution provided by the present invention is:

[0005] A bursting protection device includes a accommodating portion, the top of which is connected to a control chamber arranged inside a sampler through a connecting pipe, a linkage shut-off valve is installed on the connecting pipe above the accommodating portion, and a trigger component is provided in the accommodating portion. The trigger component triggers the linkage shut-off valve to open and close, and the linkage shut-off valve is connected to an alarm switch arranged on the accommodating portion.

[0006] Preferably, the trigger component includes a float and a trigger rod fixedly arranged on the top of the float, and the upper end of the trigger rod extends into the connecting pipe and is connected to the linkage shut-off valve.

[0007] Preferably, one side of the accommodating portion is connected to the air bag provided at the tail of the sampler through an air inlet pipe.

[0008] Preferably, a drain valve is provided at the bottom of the accommodating portion, and the air inlet pipe is spaced a certain distance from the drain valve in the vertical direction.

[0009] Preferably, the drain valve is manually operated.

[0010] Preferably, a shell is provided outside the accommodating portion, the linkage shut-off valve, the alarm switch and the drain valve to accommodate these components, and openings for the passage thereof are provided at the top of the shell corresponding to the connecting pipe and at the side wall corresponding to the air inlet pipe.

[0011] The connecting pipe and the drain valve are both made of stainless steel.

[0012] The beneficial effects of the present invention are as follows: since the float arranged in the accommodating part falls due to gravity under normal working conditions, the trigger rod triggers the linkage cut-off valve to open, so that the airbag is connected to the control chamber. When the airbag is damaged and water enters the accommodating part, the float floats up due to the buoyancy of the water, and the trigger rod triggers the linkage cut-off valve to close, so that the water in the accommodating part will not enter the control chamber through the connecting pipe, and the alarm switch connected to the linkage cut-off valve is used to alarm to prompt technicians to perform maintenance.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] See also Figure 1 and Figure 2 A bursting protection device includes a accommodating portion 1, the top of which is connected to a control chamber arranged inside a sampler through a connecting pipe 2, a linkage shut-off valve 3 is installed on the connecting pipe 2 above the accommodating portion 1, and a touch component 4 is provided in the accommodating portion 1. The touch component 4 triggers the linkage shut-off valve 3 to open and close, and the linkage shut-off valve 3 is connected to an alarm switch 5 arranged on the accommodating portion 1.

[0022] In this embodiment, the touch component 4 includes a float 41 and a trigger rod 42 fixedly arranged on the top of the float 41. The upper end of the trigger rod 42 extends into the connecting pipe 2 and is connected to the linkage cut-off valve 3. The float 41 floats up and down to drive the trigger rod 42 to move up and down, thereby controlling the opening and closing of the linkage cut-off valve 3, so that the accommodating part 1 is connected or disconnected with the control chamber set inside the sampler.

[0023] One side of the accommodating portion 1 is connected to the air bag provided at the tail of the sampler through the air inlet pipe 6, and the air is drawn into the control chamber through the air inlet pipe 6, the accommodating portion 1 and the connecting pipe 2 for pressure regulation.

[0024] A drain valve 7 is provided at the bottom of the accommodating portion 1 for draining water from the accommodating portion 1. The air inlet pipe 6 is vertically spaced a certain distance from the drain valve 7. The drain valve 7 is manually operated so that a certain amount of water is always maintained in the accommodating portion 1 to ensure that the float 41 always floats up when there is no manual drainage, so that the linked shut-off valve 3 is always in a closed state to prevent water from overflowing from the air outlet.

[0025] A shell 8 is provided outside the accommodating portion 1, the linkage shut-off valve 3, the alarm switch 5 and the drain valve 7 for accommodating these components. The top of the shell 8 is provided with an opening corresponding to the connecting pipe 2 and the side wall is provided with an opening corresponding to the air inlet pipe 6 for the passage thereof.

[0026] The connecting pipe (2) and the drain valve (7) are both made of stainless steel, which prolongs their service life.

[0027] Example 1:

[0028] See also Figure 1 During normal operation, the float 41 falls due to its own gravity, the trigger rod 42 triggers the linkage shut-off valve 3 to open, the connecting pipe 2 between the accommodating part 1 and the control chamber is connected, and the gas in the airbag installed at the tail of the sampler enters the accommodating part 1 through the air inlet pipe 6, and then enters the control chamber set inside the sampler through the connecting pipe 2, completing the pressure regulation of the control chamber.

[0029] Example 2:

[0030] See also Figure 2When the airbag ruptures and leaks, or the connection between the airbag and the air intake pipe 6 leaks, river water enters the accommodating part 1 from the rupture, and the float 41 placed in the accommodating part 1 floats up due to the buoyancy of the water. The trigger rod 42 triggers the linkage shut-off valve 3 to close, thereby cutting off the connection channel between the accommodating part 1 and the control chamber, so that the river water in the accommodating part 1 will not enter the control chamber through the connecting pipe 2. At the same time, the alarm switch 5 connected to the linkage shut-off valve 3 starts to alarm, reminding technicians to carry out maintenance.

[0031] There is a certain distance between the air inlet pipe 6 and the bottom of the accommodating portion 1 in the vertical direction, and the drainage of the accommodating portion 1 is done manually, so that the accommodating portion 1 always maintains a certain amount of water to ensure that the float 41 always floats up in the absence of manual drainage, that is, the linkage shut-off valve 3 is always closed, thereby blocking water from entering the control chamber through the connecting pipe 2.

[0032] The entire explosion protection device is arranged in the housing 7, which is convenient for installation and movement of the equipment.

[0033] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention. Other devices that are the same or similar to the above devices are also within the scope of protection of the present invention.
