Description

Technical Field

[0001] This utility model relates to the field of electrostatic release technology, specifically to an electrostatic release device for a thermal expansion agent. Background Technology

[0002] Thermal expansion agents are materials or chemical substances that expand at high temperatures. They are widely used in building materials, refractory materials, and sealing materials to compensate for the thermal expansion or contraction of materials at high temperatures, thereby preventing cracking, deformation, or other structural problems. While ensuring suitable temperature and humidity conditions, thermal expansion agents must be stored away from smoke, fire, and strong static electricity. Friction is unavoidable during transportation and handling of thermal expansion agents. Friction between different materials can easily generate static electricity. Therefore, during handling, personnel need to discharge static electricity, and the thermal expansion agent material itself needs to be de-staticated. Utility Model Content

[0003] The purpose of this invention is to provide a static electricity release device for thermal expansion agents, in order to solve the problem mentioned in the background art that friction is unavoidable during the transportation and handling of thermal expansion agents, and static electricity is easily generated by friction between different materials. During handling, it is necessary for workers to release static electricity while simultaneously releasing static electricity from the thermal expansion agent material.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a thermal expansion agent electrostatic release device, comprising a contact rod, a handle at the middle of one end of the contact rod, a sheath fitted onto the outer surface of the handle, the sheath being fixedly connected to the contact rod by bolts, a protective edge on the side of the sheath near the contact rod, the protective edge being fitted onto the contact rod, a core rod penetrating between the contact rod and the handle at the middle, the core rod extending beyond the handle to the outside of the handle, a first connecting end at the outer end of the core rod and outside the handle, a fixing bolt connecting the first connecting end to the core rod by threads, a second connecting end on the other side outside the first connecting end, and a grounding wire connecting the first connecting end and the second connecting end.

[0005] Preferably, the contact rod is a rod-shaped structure with a circular arc cross-section, and both the upper and lower ends of the contact rod have a cross-section at the middle position, and the end of the contact rod away from the handle has a circular arc end.

[0006] Preferably, the handle is a rod-shaped structure with a square cross-section, and the sheath is a hollow tubular structure made of rubber, with the hollow structure of the sheath corresponding to the handle.

[0007] Preferably, the contact rod and the handle are integrally machined from aluminum alloy, and the core rod is a solid copper round rod structure.

[0008] Preferably, the first connection terminal and the second connection terminal are clamped and fixed to the grounding wire by bending.

[0009] Compared with the prior art, the beneficial effects of this utility model are: friction is unavoidable during the transportation and handling of thermal expansion agents, and static electricity is easily generated by friction between different materials. During handling, while the staff needs to release static electricity, the staff can insert a static electricity release device into the bagged thermal expansion agent to release the static electricity generated inside the bagged thermal expansion agent, thus avoiding the risk caused by accidental release of static electricity.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a device for electrostatic release of thermal expansion agent, including a contact rod 1. A handle 2 is provided at the middle of one end of the contact rod 1. A protective sleeve 3 is sleeved on the outer surface of the handle 2. The protective sleeve 3 is fixedly connected to the contact rod 1 by bolts. A protective edge 4 is provided on the side of the protective sleeve 3 near the contact rod 1. The protective edge 4 is sleeved on the contact rod 1. A core rod 5 is provided through the middle of the contact rod 1 and the handle 2. The core rod 5 extends through the handle 2 and out to the outside of the handle 2. A first connecting end 6 is provided at the outer end of the core rod 5 and on the outside of the handle 2. A fixing bolt 7 is threadedly connected between the first connecting end 6 and the core rod 5. A second connecting end 8 is provided on the other side of the first connecting end 6. A grounding wire 9 is connected between the first connecting end 6 and the second connecting end 8.

[0018] During use, the staff first buries a grounding base at the location where the thermal expansion agent needs to be stored. The staff then connects the second connecting end 8 to the grounding base with bolts, thereby connecting one end of the grounding wire 9 to the grounding base and the other end of the grounding wire 9 to the first connecting end 6. The first connecting end 6 is connected to the core rod 5 by fixing bolts 7. The staff holds the protective sleeve 3, which is fitted onto the handle 2 on the contact rod 1. The protective sleeve 3 is provided with a protective edge 4, which is fitted onto the outer edge of the contact rod 1 to prevent the staff from directly contacting the contact rod 1. The staff holds the protective sleeve 3 and moves the contact rod 1 into the bag of thermal expansion agent. Static electricity that may exist between the thermal expansion agents is transferred to the grounding base through the contact rod 1, the core rod 5, and the grounding wire 9, thereby eliminating the static electricity.

[0019] The contact rod 1 is a rod-shaped structure with a circular arc cross-section. The middle of the upper and lower ends of the contact rod 1 is provided with a cross-section 10. The end of the contact rod 1 away from the handle 2 is provided with a circular arc end 11. The cross-section 10 at the upper and lower ends of the contact rod 1 increases the contact area between the contact rod 1 and the bagged thermal expansion agent. The circular arc end 11 at the other end of the contact rod 1 avoids damage to the thermal expansion agent packaging bag caused by the contact rod 1.

[0020] The handle 2 is a rod-shaped structure with a square cross-section, and the sheath 3 is a hollow tubular structure made of rubber. The hollow structure of the sheath 3 corresponds to the handle 2. The handle 2, designed with a square rod-shaped structure, ensures a firm connection between the sheath 3 and the handle 2.

[0021] The contact rod 1 and the handle 2 are integrally machined from aluminum alloy, and the core rod 5 is a solid copper round rod structure. The aluminum alloy contact rod 1 and handle 2 improve the wear resistance of the contact rod 1 and handle 2, and the copper core rod 5 improves the conductivity.

[0022] The first connecting end 6 and the second connecting end 8 clamp and fix the grounding wire 9 by bending, and the grounding wire 9 has a spiral structure, which increases the relative working area of ​​the grounding wire 9.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
