[0031] The specific embodiments of the utility model will be described below in combination with the drawings:

[0032] As Figure 1 shown, the I type battery constant temperature cabin provided by the embodiment includes a battery constant temperature cabin body 1, and a wire inlet 2 for entering and exiting a cable is arranged on the battery constant temperature cabin body 1. Different from the existing direct plugging cable sealing mode, in the embodiment, a wire sealing device is arranged at the wire inlet 2 and used for sealing the entering and exiting cable. The arrangement direction of the wire sealing device can be selected according to the actual situation and is not limited to the direction shown in the figure.

[0033] As Figure 2 , Figure 3 shown, the cable sealing device includes a base 3, a wire inlet device 4 and a fastening device 5. The base 3 is in a cylindrical structure and is made of plastic or metal and is fixed at the wire inlet 2. In the embodiment, the base 3 is fixed by adhesion and can also be fixed by other ways.

[0034] The inside of the base 3 is provided with a through hole 32 for mounting the wire inlet device 4 penetrating the cable. Two slots 31 are symmetrically arranged on the inner side wall of the base 3 and used for mounting the fastening device 5. The top position of the base 3 corresponding to the slots 31 is also provided with bolt holes 33 matched with the fastening device 5.

[0035] As Figure 4 , Figure 5 shown, the wire inlet device 4 is in a cylindrical structure and is made of rubber. The inside of the wire inlet device 4 is provided with a cable passing hole 41 for penetrating the cable 45 and sealing treatment by fireproof sealing cement 46.

[0036] To achieve a better sealing effect, the inlet device 4 is divided into two parts: a thicker base 42 and a thinner plug-in end. The corresponding through hole 32 of the base 3 is also divided into a base through hole and a plug-in end through hole. The inner diameter of the base 3 and the outer diameter of the inlet device 4 are almost the same. After the two are fitted together, a part of the inlet device 4 is exposed at the end of the base 3, which makes it easy to remove the inlet device 4.

[0037] A sealing gasket 44 is also provided on the base 42 near the insertion end 43. It is made of synthetic resin or graphite. The sealing gasket 44 improves the sealing effect by pressing against the inner wall of the base 3.

[0038] like Figure 6 , Figure 7 As shown, two symmetrical fastening devices 5 are installed in the slot 31 of the base 3. The main components of the fastening device 5 include a fastening block 51 and a top block 52. The fastening block 51 moves laterally in the direction shown in the figure to tighten and fix the infeed device 4. The top block 52 and the fastening block 51 form an inclined contact surface in the fastening direction of the fastening block 51. The top block 52 moves longitudinally in the direction shown in the figure to push the fastening block 51 to move laterally.

[0039] The longitudinal movement of the top block 52 can be achieved in various ways. In this embodiment, it is achieved by a top block pushing device. The top block pushing device includes a bolt 55, a column 56, and a spring 57. The column 56 is mounted on the base 3 and inserted into the top block 52. The spring 57 is fitted on the column 56. The bolt 55 is provided above the top block 52 and passes through the bolt hole 33 on the base 3. Tightening the bolt 55 causes the top block 52 to move downward. Loosening the bolt 55 causes the top block 52 to move upward under the elastic force of the spring. In this way, the top block 52 moves up and down, thereby causing the fastening block 51 to be tightened and loosened laterally.

[0040] To fix the position of the fastening block 51, a fastening block limiting plate 53 is also provided in the slot 31 of the base 3. The fastening block limiting plate 53 is provided with a fastening block through hole 54, through which the fastening block 51 passes and moves laterally.

[0041] The process for installing and replacing cables in the Type I battery constant temperature chamber of this embodiment is as follows:

[0042] After the cable 45 to be installed is prepared, it is threaded through the cable through hole 41, and then through the through hole 32 into the inside of the battery constant temperature compartment 1 to complete the internal wiring of the cable and reserve a suitable length of cable.

[0043] Fireproof sealant 46 is used to seal the cable passage hole 41. Then, the cable entry device 4 is pushed into the through hole 32 of the base 3. The two bolts 55 are tightened in sequence. The tightening of the bolts 55 causes the top block 52 to move downward, which drives the fastening block 51 to move laterally and press against the cable entry device 4. The cable entry device 4 is fixed and the cable 45 is sealed.

[0044] When replacing cable 45, loosen bolt 55. Under the elastic force of spring 57, top block 52 moves upward, fastening block 51 is released, losing its fastening effect on cable inlet device 4. Cable inlet device 4 can then be removed from base 3. After removing the old cable, install the new cable according to the above steps.

[0045] like Figure 8 As shown, as an improved implementation, in actual use, there may be situations where the battery constant temperature compartment does not need external cables temporarily. In this embodiment, a backup cable inlet device 6 is used. The backup cable inlet device 6 has the same appearance as the cable inlet device 4, but the difference is that the backup cable inlet device 6 has a solid internal structure. When external cables are not needed, the backup cable inlet device 6 temporarily blocks the cable inlet 2. When cables are needed, the cable inlet device 4 is replaced.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
